Principles of Consolidation and Basis of Presentation
The consolidated financial statements have been prepared in accordance with U.S. GAAP and include the accounts of the Company and its subsidiaries after elimination of significant intercompany accounts and transactions. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, which are necessary for a fair presentation of the results of operations in these financial statements, have been made.
The Company holds VIs, which are contractual, ownership or other interests that change with changes in the fair value of a VIE's net assets. The Company consolidates a VIE if it is the primary beneficiary, which is the party that has both the power to direct the activities that most significantly impact the financial performance of the VIE and the obligation to absorb losses or rights to receive benefits through its VIs that could potentially be significant to the VIE. To determine whether or not a VI held by the Company could potentially be significant to the VIE, both qualitative and quantitative factors regarding the nature, size, and form of the Company's involvement with the VIE are considered. The assessment of whether or not the Company is the primary beneficiary of a VIE is performed on an ongoing basis. The Company consolidates VOEs, which are entities that are not VIEs and are controlled through the Company's equity interests or by other means.
Investments in companies which are not VIEs, or where the Company is not the primary beneficiary of a VIE, that the Company has the ability to exercise significant influence over operating and financing decisions, are accounted for using the equity method of accounting. These investments are included in other assets in the Consolidated Balance Sheets at cost, adjusted to reflect the Company's portion of income, loss, or dividends of the investee. Equity investments that do not meet the criteria to be accounted for under the equity method and that do not result in consolidation of the investee are accounted for under the cost method. Cost method investments are included in other assets in the Consolidated Balance Sheets and dividends received or receivable from these investments are included as a component of other noninterest income in the Consolidated Statements of Income.
Results of operations of acquired entities are included from the date of acquisition. Results of operations associated with entities or net assets sold are included through the date of disposition. The Company reports any noncontrolling interests in its subsidiaries in the equity section of the Consolidated Balance Sheets and separately presents the income or loss attributable to the noncontrolling interest of a consolidated subsidiary in its Consolidated Statements of Income. Assets and liabilities of an acquired entity are initially recorded at their estimated fair values at the date of acquisition.
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could vary from these estimates. Certain reclassifications have been made to prior period amounts to conform to the current period presentation.
The Company evaluated subsequent events through the date its financial statements were issued.

Cash and Cash Equivalents
Cash and cash equivalents include cash and due from banks, interest-bearing deposits at other banks, Fed funds sold, and securities borrowed and purchased under agreements to resell. Cash and cash equivalents have maturities of three months or less, and accordingly, the carrying amount of these instruments is deemed to be a reasonable estimate of fair value.

Trading Activities and Securities AFS
Debt securities and marketable equity securities are classified at trade date as trading or securities AFS. Trading assets and liabilities are measured at fair value with changes in fair value recognized within noninterest income. Securities AFS are used as part of the overall asset and liability management process to optimize income and market performance over an entire interest rate cycle. Interest income and dividends on securities are recognized in interest income on an accrual basis. Premiums and discounts on debt securities are amortized or accreted as an adjustment to yield over the estimated life of the security. Securities AFS are measured at fair value with unrealized gains and losses, net of any tax effect, included in AOCI as a component of shareholders’ equity. Realized gains and losses, including OTTI, are determined using the specific identification method and are recognized as a component of noninterest income in the Consolidated Statements of Income.
Securities AFS are reviewed for OTTI on a quarterly basis. In determining whether OTTI exists for securities in an unrealized loss position, the Company assesses whether it has the intent to sell the security or, for debt securities, the Company assesses the likelihood of selling the security prior to the recovery of its amortized cost basis. If the Company intends to sell the debt security or it is more-likely-than-not that the Company will be required to sell the debt security prior to the recovery of its amortized cost basis, the debt security is written down to fair value, and the full amount of any impairment charge is recognized as a component of noninterest income in the Consolidated Statements of Income. If the Company does not intend to sell the debt security and it is more-likely-than-not that the Company will not be required to sell the debt security prior to recovery of its amortized cost basis, only the credit component of any impairment of a debt security is recognized as a component of noninterest income in the Consolidated Statements of Income, with the remaining impairment balance recorded in OCI.
The OTTI review for marketable equity securities includes an analysis of the facts and circumstances of each individual investment and focuses on the severity of loss, the length of time the fair value has been below cost, the expectation for that security's performance, the financial condition and near-term prospects of the issuer, and management's intent and ability to hold the security to recovery. A decline in value of an equity security that is considered to be other-than-temporary is recognized as a component of noninterest income in the Consolidated Statements of Income.
Nonmarketable equity securities are accounted for under the cost or equity method and are included in other assets in the Consolidated Balance Sheets. The Company reviews nonmarketable securities accounted for under the cost method on a quarterly basis, and reduces the asset value when declines in value are considered to be other-than-temporary. Equity method investments are recorded at cost, adjusted to reflect the Company’s portion of income, loss, or dividends of the investee. Realized income, realized losses, and estimated other-than-temporary unrealized losses on cost and equity method investments are recognized in noninterest income in the Consolidated Statements of Income.
For additional information on the Company’s securities activities, see Note 4, “Trading Assets and Liabilities and Derivatives,” and Note 5, “Securities Available for Sale.”

Loans Held for Sale
The Company’s LHFS generally includes certain residential mortgage loans, commercial loans, consumer indirect loans, and student loans. Loans are initially classified as LHFS when they are individually identified as being available for immediate sale and a formal plan exists to sell them. LHFS are recorded at either fair value, if elected, or the lower of cost or fair value. Origination fees and costs for LHFS recorded at LOCOM are capitalized in the basis of the loan and are included in the calculation of realized gains and losses upon sale. Origination fees and costs are recognized in earnings at the time of origination for LHFS that are elected to be measured at fair value. Fair value is derived from observable current market prices, when available, and includes loan servicing value. When observable market prices are not available, the Company uses judgment and estimates fair value using internal models, in which the Company uses its best estimates of assumptions it believes would be used by market participants in estimating fair value. Adjustments to reflect unrealized gains and losses resulting from changes in fair value and realized gains and losses upon ultimate sale of the loans are classified as noninterest income in the Consolidated Statements of Income.
The Company may transfer certain loans to LHFS measured at LOCOM. At the time of transfer, any credit losses subject to charge-off in accordance with the Company's policy are recorded as a reduction in the ALLL. Any subsequent losses, including those related to interest rate or liquidity related valuation adjustments, are recorded as a component of noninterest income in the Consolidated Statements of Income. The Company may also transfer loans from LHFS to LHFI measured at LOCOM, unless the loan was elected upon origination to be accounted for at fair value. If a LHFS for which fair value accounting was elected is transferred to held for investment, it will continue to be accounted for at fair value in the LHFI portfolio. For additional information on the Company’s LHFS activities, see Note 6, “Loans.”

Loans
Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are considered LHFI. The Company’s loan balance is comprised of loans held in portfolio, including commercial loans, consumer loans, and residential loans. Interest income on loans, except those classified as nonaccrual, is accrued based upon the outstanding principal amounts using the effective yield method.
Commercial loans (C&I, CRE, and commercial construction) are considered to be past due when payment is not received from the borrower by the contractually specified due date. The Company typically classifies commercial loans as nonaccrual when one of the following events occurs: (i) interest or principal has been past due 90 days or more, unless the loan is both well secured and in the process of collection; (ii) collection of contractual interest or principal is not anticipated; or (iii) income for the loan is recognized on a cash basis due to the deterioration in the financial condition of the debtor. When a loan is placed on nonaccrual, accrued interest is reversed against interest income. Interest income on commercial nonaccrual loans, if recognized, is recognized after the principal has been reduced to zero. If and when commercial borrowers demonstrate the ability to repay a loan classified as nonaccrual in accordance with its contractual terms, the loan may be returned to accrual status upon meeting all regulatory, accounting, and internal policy requirements.
Consumer loans (guaranteed and private student loans, other direct, indirect, and credit card) are considered to be past due when payment is not received from the borrower by the contractually specified due date. Guaranteed student loans continue to accrue interest regardless of delinquency status because collection of principal and interest is reasonably assured. Other direct and indirect loans are typically placed on nonaccrual when payments have been past due for 90 days or more except when the borrower has declared bankruptcy, in which case, they are moved to nonaccrual status once they become 60 days past due. When a loan is placed on nonaccrual, accrued interest is reversed against interest income. Interest income on nonaccrual loans, if recognized, is recognized on a cash basis. Nonaccrual consumer loans are typically returned to accrual status once they are no longer past due.
Residential loans (guaranteed and nonguaranteed residential mortgages, residential home equity products, and residential construction) are considered to be past due when a monthly payment is due and unpaid for one month. Guaranteed residential mortgages continue to accrue interest regardless of delinquency status because collection of principal and interest is reasonably assured by the government. Nonguaranteed residential mortgages and residential construction loans are generally placed on nonaccrual when three payments are past due. Residential home equity products are generally placed on nonaccrual when payments are 90 days past due. The exceptions for nonguaranteed residential mortgages, residential construction loans, and residential home equity products are: (i) when the borrower has declared bankruptcy, in which case, they are moved to nonaccrual status once they become 60 days past due, (ii) loans discharged in Chapter 7 bankruptcy that have not been reaffirmed by the borrower, in which case, they are reclassified as TDRs and moved to nonaccrual status, and (iii) second lien loans, which are classified as nonaccrual when the first lien loan is classified as nonaccrual, even if the second lien loan is performing. When a loan is placed on nonaccrual, accrued interest is reversed against interest income. Interest income on nonaccrual loans is recognized on a cash basis. Nonaccrual residential loans are typically returned to accrual status once they no longer meet the delinquency threshold that resulted in them initially being moved to nonaccrual status, with the exception of the aforementioned Chapter 7 bankruptcy loans, which remain on nonaccrual until there is six months of payment performance following discharge by the bankruptcy court.
TDRs are loans in which the borrower is experiencing financial difficulty at the time of restructure and the borrower received an economic concession either from the Company or as the product of a bankruptcy court order. To date, the Company’s TDRs have been predominantly first and second lien residential mortgages and home equity lines of credit. Prior to granting a modification of a borrower’s loan terms, the Company performs an evaluation of the borrower’s financial condition and ability to service under the potential modified loan terms. The types of concessions generally granted are extensions of the loan maturity date and/or reductions in the original contractual interest rate. Typically, if a loan is accruing interest at the time of modification, the loan remains on accrual status and is subject to the Company’s charge-off and nonaccrual policies. See the “Allowance for Credit Losses” section below for further information regarding these policies. If a loan is on nonaccrual before it is determined to be a TDR then the loan remains on nonaccrual. Typically, TDRs may be returned to accrual status if there has been at least a six month sustained period of repayment performance by the borrower. Generally, once a loan becomes a TDR, the Company expects that the loan will continue to be reported as a TDR for its remaining life, even after returning to accruing status, unless the modified rates and terms at the time of modification were available to the borrower in the market or the loan is subsequently restructured with no concession to the borrower and the borrower is no longer in financial difficulty. Interest income recognition on impaired loans is dependent upon accrual status, TDR designation, and loan type as discussed above.
For loans accounted for at amortized cost, fees and incremental direct costs associated with the loan origination and pricing process, as well as premiums and discounts, are deferred and amortized as level yield adjustments over the respective loan terms. Fees received for providing loan commitments that result in funded loans are recognized over the term of the loan as an adjustment of the yield. If a loan is never funded, the commitment fee is recognized in noninterest income at the expiration of the commitment period. Origination fees and costs are recognized in noninterest income and expense at the time of origination for newly-originated loans that are accounted for at fair value. For additional information on the Company's loans activities, see Note 6, “Loans.”

Allowance for Credit Losses
The allowance for credit losses is composed of the ALLL and the reserve for unfunded commitments. The Company’s ALLL is the amount considered appropriate to absorb probable current inherent losses in the LHFI portfolio based on management’s evaluation of the size and current risk characteristics of the loan portfolio. In addition to the review of credit quality through ongoing credit review processes, the Company employs a variety of modeling and estimation techniques to measure credit risk and construct an appropriate and adequate ALLL. Quantitative and qualitative asset quality measures are considered in estimating the ALLL. Such evaluation considers a number of factors for each of the loan portfolio segments, including, but not limited to, net charge-off trends, internal risk ratings, changes in internal risk ratings, loss forecasts, collateral values, geographic location, delinquency rates, nonperforming and restructured loan status, origination channel, product mix, underwriting practices, industry conditions, and economic trends. Additionally, refreshed FICO scores are considered for consumer and residential loans and single name borrower concentration is considered for commercial loans. These credit quality factors are incorporated into various loss estimation models and analytical tools utilized in the ALLL process and/or are qualitatively considered in evaluating the overall reasonableness of the ALLL.
Large commercial (all loan classes) nonaccrual loans and certain consumer (other direct, indirect, and credit card), residential (nonguaranteed residential mortgages, residential home equity products, and residential construction), and certain commercial (all classes) loans whose terms have been modified in a TDR are reviewed to determine the amount of specific allowance required in accordance with applicable accounting guidance. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due, including principal and interest, according to the contractual terms of the agreement. If necessary, an allowance is established for these specifically evaluated impaired loans. The specific allowance established for these loans is based on a thorough analysis of the most probable source of repayment, including the present value of the loan’s expected future cash flows, the loan’s estimated market value, or the estimated fair value of the underlying collateral. Any change in the present value attributable to the passage of time is recognized through the provision for credit losses.
General allowances are established for loans and leases grouped into pools based on similar characteristics. In this process, general allowance factors are based on an analysis of historical charge-off experience, expected loss factors derived from the Company's internal risk rating process, portfolio trends, and regional and national economic conditions. Other adjustments may be made to the ALLL after an assessment of internal and external influences on credit quality that may not be fully reflected in the historical loss or risk rating data. These influences may include elements such as changes in credit underwriting, concentration risk, macroeconomic conditions, and/or recent observable asset quality trends.
The Company’s charge-off policy meets regulatory minimums. Commercial loans are charged off when they are considered uncollectible. Losses on unsecured consumer loans are generally recognized at 120 days past due, except for losses on guaranteed student loans which are recognized at 270 days past due. However, if the borrower is in bankruptcy, the loan is charged-off in the month the loan becomes 60 days past due. Losses, as appropriate, on secured consumer loans, including residential real estate, are typically recognized at 120 or 180 days past due, depending on the loan and collateral type, in compliance with the FFIEC guidelines. However, if the borrower is in bankruptcy, the secured asset is evaluated once the loan becomes 60 days past due. The loan value in excess of the secured asset value is written down or charged-off after the valuation occurs. Additionally, if a residential loan is discharged in Chapter 7 bankruptcy and not reaffirmed by the borrower, the Company's policy is to immediately charge-off the excess of the carrying amount over the fair value of the collateral.
The Company uses numerous sources of information when evaluating a property’s value. Estimated collateral valuations are based on appraisals, broker price opinions, recent sales of foreclosed properties, automated valuation models, other property-specific information, and relevant market information, supplemented by the Company’s internal property valuation analysis. The value estimate is based on an orderly disposition of the property, inclusive of marketing costs. In limited instances, the Company adjusts externally provided appraisals for justifiable and well-supported reasons, such as an appraiser not being aware of certain property-specific factors or recent sales information. Appraisals generally represent the “as is” value of the property but may be adjusted based on the intended disposition strategy of the property.
For commercial and CRE loans secured by property, an acceptable third party appraisal or other form of evaluation, as permitted by regulation, is obtained prior to the origination of the loan and upon a subsequent transaction involving a material change in terms. In addition, updated valuations may be obtained during the life of a loan, as appropriate, such as when a loan's performance materially deteriorates. In situations where an updated appraisal has not been received or a formal evaluation performed, the Company monitors factors that can positively or negatively impact property value, such as the date of the last valuation, the volatility of property values in specific markets, changes in the value of similar properties, and changes in the characteristics of individual properties. Changes in collateral value affect the ALLL through the risk rating or impaired loan evaluation process. Charge-offs are recognized when the amount of the loss is quantifiable and timing is known. The charge-off is measured based on the difference between the loan’s carrying value, including deferred fees, and the estimated realizable value of the property, net of estimated selling costs. When valuing a property for the purpose of determining a charge-off, a third party appraisal or an independently derived internal evaluation is generally employed.
For nonguaranteed mortgage loans secured by residential property where the Company is proceeding with a foreclosure action, a new valuation is obtained prior to the loan becoming 180 days past due and, if required, the loan is written down to its realizable value, net of estimated selling costs. In the event the Company decides not to proceed with a foreclosure action, the full balance of the loan is charged-off. If a loan remains in the foreclosure process for 12 months past the original charge-off, the Company obtains a new valuation annually. Any additional loss based on the new valuation is charged-off. At foreclosure, a new valuation is obtained and the loan is transferred to OREO at the new valuation less estimated selling costs; any loan balance in excess of the transfer value is charged-off. Estimated declines in value of the residential collateral between these formal evaluation events are captured in the ALLL based on changes in the house price index in the applicable MSA or other market information.
In addition to the ALLL, the Company also estimates probable losses related to unfunded lending commitments, such as letters of credit and binding unfunded loan commitments. Unfunded lending commitments are analyzed and segregated by risk based on the Company’s internal risk rating scale. These risk classifications, in combination with probability of commitment usage, existing economic conditions, and any other pertinent information, result in the estimation of the reserve for unfunded lending commitments. The reserve for unfunded lending commitments is reported on the Consolidated Balance Sheets in other liabilities and the provision associated with changes in the unfunded lending commitment reserve is reported in the Consolidated Statements of Income in provision for credit losses. For additional information on the Company's allowance for credit loss activities, see Note 7, “Allowance for Credit Losses.”

Premises and Equipment
Premises and equipment are carried at cost less accumulated depreciation and amortization. Depreciation is calculated predominantly using the straight-line method over the assets’ estimated useful lives. Leasehold improvements are amortized using the straight-line method over the shorter of the improvements' estimated useful lives or the lease term. Construction and software in process includes costs related to in-process branch expansion, branch renovation, and software development projects. Upon completion, branch and office related projects are maintained in premises and equipment while completed software projects are reclassified to other assets in the Consolidated Balance Sheets. Maintenance and repairs are charged to expense, and improvements that extend the useful life of an asset are capitalized and depreciated over the remaining useful life. Premises and equipment are evaluated for impairment whenever events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. For additional information on the Company’s premises and equipment activities, see Note 8, “Premises and Equipment.”

Goodwill and Other Intangible Assets
Goodwill represents the excess purchase price over the fair value of identifiable net assets of acquired companies. Goodwill is assigned to reporting units, which are operating segments or one level below an operating segment, as of the acquisition date; more specifically, it is assigned to units that are expected to benefit from the synergies of the business combination.
Goodwill is tested at the reporting unit level for impairment, at least annually, or as events and circumstances change that would more-likely-than-not reduce the fair value of a reporting unit below its carrying amount. In the third quarter of 2015, the Company elected to prospectively change the date of its annual goodwill impairment test from September 30 to October 1 to better align the timing of the test with the availability of key inputs.
If, after considering all relevant events and circumstances, the Company determines it is not more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, then performing an impairment test is not necessary. If the Company elects to bypass the qualitative analysis, or concludes via qualitative analysis that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying value, a two-step goodwill impairment test is performed. In the first step, the fair value of each reporting unit is compared with its carrying value. If the fair value is greater than the carrying value, then the reporting unit's goodwill is deemed not to be impaired. If the fair value is less than the carrying value, then the second step is performed, which measures the amount of impairment by comparing the carrying amount of goodwill to its implied fair value. If the implied fair value of the goodwill exceeds the carrying amount, there is no impairment. If the carrying amount exceeds the implied fair value of the goodwill, an impairment charge is recorded for the excess.
Identified intangible assets that have a finite life are amortized over their useful lives and are evaluated for impairment whenever events or changes in circumstances indicate the carrying amount of the assets may not be recoverable. For additional information on the Company’s activities related to goodwill and other intangibles, see Note 9, “Goodwill and Other Intangible Assets.”

MSRs
The Company recognizes as assets the rights to service mortgage loans, either when the loans are sold and the associated servicing rights are retained or when servicing rights are purchased from a third party. The Company has elected to measure all MSRs at fair value. Fair value is determined by projecting net servicing cash flows, which are then discounted to estimate fair value. The Company actively hedges the change in fair value of its MSRs. The fair value of MSRs is impacted by a variety of factors, including prepayment assumptions, discount rates, delinquency rates, contractually specified servicing fees, servicing costs, and underlying portfolio characteristics. The underlying assumptions and estimated values are corroborated by values received from independent third parties and comparisons to market transactions. MSRs are reported on the Consolidated Balance Sheets in other intangible assets. Both servicing fees, which are recognized when they are received, and changes in the fair value of MSRs are reported in mortgage servicing related income in the Consolidated Statements of Income. For additional information on the Company’s servicing rights, see Note 9, “Goodwill and Other Intangible Assets.”

Other Real Estate Owned
Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at the lower of the loan’s cost basis or the asset’s fair value at the date of foreclosure, less estimated selling costs. To the extent fair value, less cost to sell, is less than the loan’s cost basis, the difference is charged to the ALLL at the date of transfer into OREO. The Company estimates market values based primarily on appraisals and other market information. Any subsequent changes in value as well as gains or losses from the disposition on these assets are reported in noninterest expense in the Consolidated Statements of Income. For additional information on the Company's activities related to OREO, see Note 18, “Fair Value Election and Measurement.”

Loan Sales and Securitizations
The Company sells and at times may securitize loans and other financial assets. When the Company securitizes assets, it may hold a portion of the securities issued, including senior interests, subordinated and other residual interests, interest-only strips, and principal-only strips, all of which are considered retained interests in the transferred assets. Retained securitized interests are recognized and initially measured at fair value. The interests in securitized assets held by the Company are typically classified as either securities AFS or trading assets and measured at fair value, which is based on independent, third party market prices, market prices for similar assets, or discounted cash flow analyses. If market prices are not available, fair value is calculated using management’s best estimates of key assumptions, including credit losses, loan repayment speeds, and discount rates commensurate with the risks involved.
The Company transfers first lien residential mortgage loans in conjunction with GSE securitization transactions, whereby the loans are exchanged for cash or securities that are readily redeemable for cash and servicing rights are retained. Net gains on the sale of residential mortgage loans are recorded at inception of the associated IRLCs within mortgage production related income in the Consolidated Statements of Income. The net gains reflect the change in value of the loans resulting from changes in interest rates from the time the Company enters into IRLCs with borrowers and when the loan is closed, adjusted for pull through rates and excluding hedge transactions initiated to mitigate this market risk. For additional information on the Company’s securitization activities, see Note 10, “Certain Transfers of Financial Assets and Variable Interest Entities.”

Income Taxes
The provision for income taxes is based on income and expense reported for financial statement purposes after adjustment for permanent differences such as interest income from lending to tax-exempt entities and tax credits from community reinvestment activities. The deferral method of accounting is used on investments that generate investment tax credits, such that the investment tax credits are recognized as a reduction to the related asset. Deferred income tax assets and liabilities result from differences between the timing of the recognition of assets and liabilities for financial reporting purposes and for income tax purposes. These assets and liabilities are measured using the enacted tax rates and laws that are expected to apply in the periods in which the deferred tax assets or liabilities are expected to be realized. Subsequent changes in the tax laws require adjustment to these assets and liabilities with the cumulative effect included in the provision for income taxes for the period in which the change is enacted. A valuation allowance is recognized for a DTA if, based on the weight of available evidence, it is more-likely-than-not that some portion or all of the DTA will not be realized. In computing the income tax provision, the Company evaluates the technical merits of its income tax positions based on current legislative, judicial, and regulatory guidance. Interest and penalties related to the Company’s tax positions are recognized as a component of the income tax provision. For additional information on the Company’s activities related to income taxes, see Note 14, “Income Taxes.”

Earnings Per Share
Basic EPS is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during each period. Diluted EPS is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during each period, plus common share equivalents calculated for stock options, warrants, and restricted stock outstanding using the treasury stock method.
The Company has issued certain restricted stock awards, which are unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents. These restricted shares are considered participating securities. Accordingly, the Company calculated net income available to common shareholders pursuant to the two-class method, whereby net income is allocated between common shareholders and participating securities.
Net income available to common shareholders represents net income after preferred stock dividends, gains or losses from any repurchases of preferred stock, and dividends and allocation of undistributed earnings to the participating securities. For additional information on the Company’s EPS, see Note 12, “Net Income Per Common Share.”

Securities Sold Under Agreements to Repurchase and Securities Borrowed or Purchased Under Agreements to Resell
Securities sold under agreements to repurchase and securities borrowed or purchased under agreements to resell are accounted for as collateralized financing transactions and are recorded at the amounts at which the securities were sold or acquired, plus accrued interest. The fair value of collateral pledged or received is continually monitored and additional collateral is obtained or requested to be returned to the Company as deemed appropriate. For additional information on the collateral pledged to secure repurchase agreements, see Note 3, "Federal Funds Sold and Securities Financing Activities," Note 4, "Trading Assets and Liabilities and Derivatives," and Note 5, "Securities Available for Sale."

Guarantees
The Company recognizes a liability at the inception of a guarantee at an amount equal to the estimated fair value of the obligation. A guarantee is defined as a contract that contingently requires a company to make payment to a guaranteed party based upon changes in an underlying asset, liability, or equity security of the guaranteed party, or upon failure of a third party to perform under a specified agreement. The Company considers the following arrangements to be guarantees: certain asset purchase/sale agreements, standby letters of credit and financial guarantees, certain indemnification agreements included within third party contractual arrangements, and certain derivative contracts. For additional information on the Company’s guarantor obligations, see Note 16, “Guarantees.”
Derivative Instruments and Hedging Activities
The Company records derivative contracts at fair value in the Consolidated Balance Sheets. Accounting for changes in the fair value of a derivative is dependent upon whether or not it has been designated in a formal, qualifying hedging relationship. 
Changes in the fair value of derivatives not designated in a hedging relationship are recorded in noninterest income. This includes derivatives that the Company enters into in a dealer capacity to facilitate client transactions and as a risk management tool to economically hedge certain identified market risks, along with certain IRLCs on residential mortgage loans that are a normal part of the Company’s operations. The Company also evaluates contracts, such as brokered deposits and short-term debt, to determine whether any embedded derivatives are required to be bifurcated and separately accounted for as freestanding derivatives.
Certain derivatives used as risk management tools are also designated as accounting hedges of the Company’s exposure to changes in interest rates or other identified market risks. The Company prepares written hedge documentation for all derivatives which are designated as hedges of (1) changes in the fair value of a recognized asset or liability (fair value hedge) attributable to a specified risk or (2) a forecasted transaction, such as the variability of cash flows to be received or paid related to a recognized asset or liability (cash flow hedge). The written hedge documentation includes identification of, among other items, the risk management objective, hedging instrument, hedged item and methodologies for assessing and measuring hedge effectiveness and ineffectiveness, along with support for management’s assertion that the hedge will be highly effective. Methodologies related to hedge effectiveness and ineffectiveness are consistent between similar types of hedge transactions and include (i) statistical regression analysis of changes in the cash flows of the actual derivative and a perfectly effective hypothetical derivative, or (ii) statistical regression analysis of changes in the fair values of the actual derivative and the hedged item.
For designated hedging relationships, the Company performs retrospective and prospective effectiveness testing using quantitative methods and does not assume perfect effectiveness through the matching of critical terms. Assessments of hedge effectiveness and measurements of hedge ineffectiveness are performed at least quarterly. Changes in the fair value of a derivative that is highly effective and that has been designated and qualifies as a fair value hedge are recorded in current period earnings, along with the changes in the fair value of the hedged item that are attributable to the hedged risk. The effective portion of the changes in the fair value of a derivative that is highly effective and that has been designated and qualifies as a cash flow hedge are initially recorded in AOCI and reclassified to earnings in the same period that the hedged item impacts earnings; any ineffective portion is recorded in current period earnings.
Hedge accounting ceases on transactions that are no longer deemed effective, or for which the derivative has been terminated or de-designated. For discontinued fair value hedges where the hedged item remains outstanding, the hedged item would cease to be remeasured at fair value attributable to changes in the hedged risk and any existing basis adjustment would be recognized as an adjustment to earnings over the remaining life of the hedged item. For discontinued cash flow hedges, the unrealized gains and losses recorded in AOCI would be reclassified to earnings in the period when the previously designated hedged cash flows occur unless it was determined that transaction was probable to not occur, whereby any unrealized gains and losses in AOCI would be immediately reclassified to earnings.
It is the Company's policy to offset derivative transactions with a single counterparty as well as any cash collateral paid to and received from that counterparty for derivative contracts that are subject to ISDA or other legally enforceable netting arrangements and meet accounting guidance for offsetting treatment. For additional information on the Company’s derivative activities, see Note 17, “Derivative Financial Instruments,” and Note 18, “Fair Value Election and Measurement.”

Stock-Based Compensation
The Company sponsors various stock-based compensation plans under which RSUs, restricted stock, and performance stock units may be granted to certain employees. The Company measures the grant date fair value of stock-based compensation awards, which is expensed over the award's vesting period. Additionally, the Company estimates the number of awards for which it is probable that service will be rendered and adjusts compensation cost accordingly. Estimated forfeitures are subsequently adjusted to reflect actual forfeitures. For additional information on the Company’s stock-based compensation plans, see Note 15, “Employee Benefit Plans.”

Employee Benefits
Employee benefits expense includes expenses related to (i) net periodic benefit costs or credits associated with the pension and other postretirement benefit plans, (ii) contributions under the defined contribution plans, (iii) the amortization of restricted stock, (iv) the issuance of performance stock units, (v) historical stock option issuances, and (vi) other employee benefits costs. For additional information on the Company's employee benefit plans, see Note 15, “Employee Benefit Plans.”

Foreign Currency Transactions
Foreign denominated assets and liabilities resulting from foreign currency transactions are valued using period end foreign exchange rates and the associated interest income or expense is determined using weighted average exchange rates for the period. The Company may enter into foreign currency derivatives to mitigate its exposure to changes in foreign exchange rates. The derivative contracts are accounted for at fair value on a recurring basis with any resulting gains and losses recorded in noninterest income in the Consolidated Statements of Income.
Fair Value Measurement
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Depending on the nature of the asset or liability, the Company uses various valuation techniques and assumptions when estimating fair value. The Company prioritizes inputs used in valuation techniques based on the following fair value hierarchy:
•
Level 1 – Assets or liabilities valued using unadjusted quoted prices in active markets for identical assets or liabilities that the Company can access at the measurement date, such as publicly-traded instruments or futures contracts
•
Level 2 – Assets and liabilities valued based on observable market data for similar instruments
•
Level 3 – Assets or liabilities for which significant valuation assumptions are not readily observable in the market; instruments valued based on the best available data, some of which may be internally developed, and considers risk premiums that a market participant would require
When measuring assets and liabilities at fair value, the Company considers the principal or most advantageous market in which it would transact and considers assumptions that market participants would use when pricing the asset or liability. Assets and liabilities that are required to be measured at fair value on a recurring basis include trading securities, securities AFS, and derivative instruments. Assets and liabilities that the Company has elected to measure at fair value on a recurring basis include MSRs and certain LHFS, LHFI, trading loans, brokered time deposits, and issuances of fixed rate debt. Other assets and liabilities are measured at fair value on a non-recurring basis, such as when assets are evaluated for impairment, the basis of accounting is LOCOM, or for disclosure purposes. Examples of these non-recurring fair value measurements include certain LHFS and LHFI, OREO, certain cost or equity method investments, and long-lived assets. For additional information on the Company’s valuation of its assets and liabilities held at fair value, see Note 18, “Fair Value Election and Measurement.”

Accounting Standards Not Yet Adopted
The following table provides a brief description of accounting standards that have been issued, but are not yet adopted, that could have a material effect on the Company's financial statements:
Standard
Description
Date of Adoption
Effect on the Financial Statements or Other Significant Matters
ASU 2014-09, Revenue from Contracts with Customers
The ASU supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition, and most industry-specific guidance throughout the Industry Topics of the Codification. The core principle of the ASU is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU may be adopted either retrospectively or on a modified retrospective basis to new contracts and existing contracts with remaining performance obligations as of the effective date.
January 1, 2018
(early adoption permitted beginning January 1, 2017)
The Company is continuing to evaluate the alternative methods of adoption and the anticipated effects on the financial statements and related disclosures.

ASU 2016-01, Recognition and Measurement of Financial Assets and Liabilities
The ASU addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The main provisions require investments in equity securities to be measured at fair value through net income, unless they qualify for a practicability exception, and require fair value changes arising from changes in instrument-specific credit risk for financial liabilities that are measured under the fair value option to be recognized in other comprehensive income. With the exception of disclosure requirements that would be adopted prospectively, the ASU must be adopted on a modified retrospective basis.
January 1, 2018
(early adoption permitted beginning January 1, 2016 or 2017 for the provision related to changes in instrument-specific credit risk for financial liabilities under the fair value option)
The Company is early adopting the provision related to changes in instrument-specific credit risk beginning January 1, 2016, which will result in an immaterial reclassification from retained earnings to OCI. The prospective impact of this provision on the financial statements is a function of the principal amount of financial liabilities under the fair value option and changes in the Company's credit spreads. The Company is evaluating the impact of the remaining provisions of this ASU on the financial statements and related disclosures; however, the impact is not expected to be material.


NOTE 1 – SIGNIFICANT ACCOUNTING POLICIES
Principles of Consolidation and Basis of Presentation
The unaudited consolidated financial statements have been prepared in accordance with U.S. GAAP for interim financial information. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete consolidated financial statements. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, which are necessary for a fair presentation of the results of operations in these financial statements, have been made.
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could vary from these estimates. Certain reclassifications have been made to prior period amounts to conform to the current period presentation.
The Company evaluated subsequent events through the date its financial statements were issued.
These financial statements should be read in conjunction with the Company’s 2014 Annual Report on Form 10-K. In the third quarter of 2015, the Company elected to prospectively change the date of its annual goodwill impairment test from September 30 to October 1 to better align the timing of the test with the availability of key inputs. There have been no other significant changes to the Company’s accounting policies as disclosed in the 2014 Annual Report on Form 10-K.

ASU 2015-02, Amendments to the Consolidation Analysis
The ASU rescinds the indefinite deferral of previous amendments to ASC Topic 810 for certain entities and amends components of the consolidation analysis under ASC Topic 810, including evaluating limited partnerships and similar legal entities, evaluating fees paid to a decision maker or service provider as a variable interest, the effects of fee arrangements and/or related parties on the primary beneficiary determination and investment fund specific matters. The ASU may be adopted either retrospectively or on a modified retrospective basis.
January 1, 2016
The Company will adopt this ASU on a modified retrospective basis. The Company is continuing to evaluate the impact of this ASU on the financial statements and related disclosures; however, adoption is not expected to materially impact the Company's financial position, results of operations, or EPS.

Securities purchased under agreements to resell are primarily collateralized by U.S. government or agency securities and are carried at the amounts at which the securities will be subsequently resold. Securities borrowed are primarily collateralized by corporate securities. The Company borrows securities and purchases securities under agreements to resell as part of its securities financing activities. On the acquisition date of these securities, the Company and the related counterparty agree on the amount of collateral required to secure the principal amount loaned under these arrangements. The Company monitors collateral values daily and calls for additional collateral to be provided as warranted under the agreement. At December 31, 2015 and 2014, the total market value of collateral held was $1.2 billion and $1.1 billion, respectively, of which $73 million and $222 million was repledged, respectively.
Securities Sold Under Agreements to Repurchase

For these securities sold under agreements to repurchase, the Company would be obligated to provide additional collateral in the event of a significant decline in fair value of the collateral pledged. This risk is managed by monitoring the liquidity and credit quality of the collateral, as well as the maturity profile of the transactions.
Netting of Securities - Repurchase and Resell Agreements
The Company has various financial assets and financial liabilities that are subject to enforceable master netting agreements or similar agreements. The Company's derivatives that are subject to enforceable master netting agreements or similar agreements are discussed in Note 17, "Derivative Financial Instruments." The following table presents the Company's securities borrowed or purchased under agreements to resell and securities sold under agreements to repurchase that are subject to MRAs. Under the terms of the MRA, all transactions between the Company and a counterparty constitute a single business relationship such that in the event of default, the nondefaulting party is entitled to set off claims and apply property held against obligations owed. Any payments, deliveries, or other transfers may be applied against each other and presented net on the Company's Consolidated Balance Sheets, provided criteria are met that permit balance sheet netting. At December 31, 2015 and 2014, there were no such transactions subject to legally enforceable MRAs that were eligible for balance sheet netting.
Financial instrument collateral received or pledged related to exposures subject to legally enforceable MRAs are not netted on the Consolidated Balance Sheets, but are presented in the following table as a reduction to the net amount presented in the Consolidated Balance Sheets to derive the held/pledged financial instruments by counterparty. The collateral amounts held/pledged are limited for presentation purposes to the related recognized asset/liability balance for each counterparty, and accordingly, do not include excess collateral received/pledged.

Various trading and derivative instruments are used as part of the Company’s overall balance sheet management strategies and to support client requirements executed through the Bank and/or the Company's broker/dealer subsidiary. The Company manages the potential market volatility associated with trading instruments with appropriate risk management strategies. The size, volume, and nature of the trading products and derivative instruments can vary based on economic conditions as well as client-specific and Company-specific asset or liability positions. Product offerings to clients include debt securities, loans traded in the secondary market, equity securities, derivative contracts, and other similar financial instruments. Other trading-related activities include acting as a market maker for certain debt and equity security transactions, derivative instrument transactions, and foreign exchange transactions. The Company also uses derivatives to manage its interest rate and market risk from non-trading activities. The Company has policies and procedures to manage market risk associated with client trading and non-trading activities, and assumes a limited degree of market risk by managing the size and nature of its exposure. For valuation assumptions related to the Company's trading products, as well as additional information on our derivative instruments, see Note 17, “Derivative Financial Instruments,” and the “Trading Assets and Derivative Instruments and Securities Available for Sale” section of Note 18, “Fair Value Election and Measurement.”
The Company pledged $986 million and $1.1 billion of trading securities to secure $950 million and $1.1 billion of repurchase agreements at December 31, 2015 and December 31, 2014, respectively. Additionally, the Company pledged $393 million and $202 million of trading securities to secure certain derivative agreements at December 31, 2015 and December 31, 2014, respectively, and pledged $40 million of trading securities under other arrangements at both December 31, 2015 and December 31, 2014.

Securities AFS in an Unrealized Loss Position
The Company held certain investment securities AFS where amortized cost exceeded fair value, resulting in unrealized loss positions. Market changes in interest rates and credit spreads may result in temporary unrealized losses as the market prices of securities fluctuate. At December 31, 2015, the Company did not intend to sell these securities nor was it more-likely-than-not that the Company would be required to sell these securities before their anticipated recovery or maturity. The Company reviewed its portfolio for OTTI in accordance with the accounting policies described in Note 1, "Significant Accounting Policies."

1 OTTI securities for which credit losses have been recorded in earnings in current and/or prior periods.
2 Unrealized losses less than $0.5 million are presented as zero within the table.

At December 31, 2015, temporarily impaired securities AFS that have been in an unrealized loss position for twelve months or longer included agency MBS, federal agency securities, and one ABS collateralized by 2004 vintage home equity loans. Unrealized losses on these temporarily impaired agency MBS and federal agency securities were due to market interest rates being higher than the securities' stated coupon rates. The temporarily impaired ABS continues to receive timely principal and interest payments, and is evaluated quarterly for credit impairment. Unrealized losses on securities AFS that relate to factors other than credit are recorded in AOCI, net of tax.

Securities AFS in an unrealized loss position are evaluated quarterly for other-than-temporary credit impairment, which is determined using cash flow analyses that take into account security specific collateral and transaction structure. Future expected credit losses are determined using various assumptions, the most significant of which include default rates, prepayment rates, and loss severities. If, based on this analysis, a security is in an unrealized loss position and the Company does not expect to recover the entire amortized cost basis of the security, the expected cash flows are then discounted at the security’s initial effective interest rate to arrive at a present value amount. Credit losses on the OTTI security are recognized in earnings and reflect the difference between the present value of cash flows expected to be collected and the amortized cost basis of the security. See Note 1, "Significant Accounting Policies," for additional information regarding the Company's policy on securities AFS and related impairments.
The Company continues to reduce existing exposure on OTTI securities primarily through paydowns. In certain instances, the amount of credit losses recognized in earnings on a debt security exceeds the total unrealized losses on the security, which may result in unrealized gains relating to factors other than credit recorded in AOCI, net of tax.
During the years ended December 31, 2015, 2014, and 2013, credit impairment losses recognized on securities AFS held at the end of each period were immaterial. The accumulated balance of OTTI credit losses recognized in earnings on securities AFS held at period end was $25 million for each of the years ended December 31, 2015, 2014, and 2013. Subsequent credit losses may be recorded on securities without a corresponding further decline in fair value when there has been a decline in expected cash flows.
The following table presents a summary of the significant inputs used in determining the measurement of OTTI credit losses recognized in earnings for private MBS and ABS for the year ended December 31:

1 During the year ended December 31, 2015, all OTTI credit losses recognized in earnings related to one private MBS security with a fair value of $20 million at December 31, 2015. During the year ended December 31, 2014, OTTI credit losses recognized in earnings related to one private MBS security with a fair value of $16 million at December 31, 2014.

Assumption ranges represent the lowest and highest lifetime average estimates of each security for which credit losses were recognized in earnings. Ranges may vary from period to period as the securities for which credit losses are recognized vary. Additionally, severity may vary widely when losses are few and large.

2 Includes $1.5 billion and $1.9 billion of LHFS measured at fair value at December 31, 2015 and 2014, respectively.
During the years ended December 31, 2015 and 2014, the Company transferred $1.8 billion and $3.3 billion in LHFI to LHFS, and $741 million and $44 million in LHFS to LHFI, respectively. In addition to sales of mortgage LHFS in the normal course of business, the Company sold $2.1 billion and $4.0 billion in loans and leases for gains of $22 million and $83 million, during the years ended December 31, 2015 and 2014, respectively.
At December 31, 2015 and 2014, the Company had $23.6 billion and $26.5 billion of net eligible loan collateral pledged to the Federal Reserve discount window to support $17.2 billion and $18.4 billion of available, unused borrowing capacity, respectively.
At December 31, 2015 and 2014, the Company had $33.7 billion and $31.2 billion of net eligible loan collateral pledged to the FHLB of Atlanta to support $28.5 billion and $24.3 billion of available borrowing capacity, respectively. The available FHLB borrowing capacity at December 31, 2015 was used to support $408 million of long-term debt and $6.7 billion of letters of credit issued on the Company's behalf. At December 31, 2014, the available FHLB borrowing capacity was used to support $4.0 billion of long-term debt, $4.0 billion of short-term debt, and $7.9 billion of letters of credit issued on the Company's behalf.
Credit Quality Evaluation
The Company evaluates the credit quality of its loan portfolio by employing a dual internal risk rating system, which assigns both PD and LGD ratings to derive expected losses. Assignment of PD and LGD ratings are predicated upon numerous factors, including consumer credit risk scores, rating agency information, borrower/guarantor financial capacity, LTV ratios, collateral type, debt service coverage ratios, collection experience, other internal metrics/analyses, and/or qualitative assessments.
For the commercial portfolio, the Company believes that the most appropriate credit quality indicator is an individual loan’s risk assessment expressed according to the broad regulatory agency classifications of Pass or Criticized. The Company conforms to the following regulatory classifications for Criticized assets: Other Assets Especially Mentioned (or Special Mention), Adversely Classified, Doubtful, and Loss. However, for the purposes of disclosure, management believes the most meaningful distinction within the Criticized categories is between Accruing Criticized (which includes Special Mention and a portion of Adversely Classified) and Nonaccruing Criticized (which includes a portion of Adversely Classified and Doubtful and Loss). This distinction identifies those relatively higher risk loans for which there is a basis to believe that the Company will not collect all amounts due under those loan agreements. The Company's risk rating system is granular, with multiple risk ratings in both the Pass and Criticized categories. Pass ratings reflect relatively low PDs, whereas, Criticized assets have higher PDs. The granularity in Pass ratings assists in the establishment of pricing, loan structures, approval requirements, reserves, and ongoing credit management requirements. Commercial risk ratings are refreshed at least annually, or more frequently as appropriate, based upon considerations such as market conditions, borrower characteristics, and portfolio trends. Additionally, management routinely reviews portfolio risk ratings, trends, and concentrations to support risk identification and mitigation activities. The increase in criticized accruing and nonaccruing C&I loans at December 31, 2015 compared to December 31, 2014, as presented in the following risk rating table, was primarily driven by downgrades of loans in the energy industry vertical.
For consumer and residential loans, the Company monitors credit risk based on indicators such as delinquencies and FICO scores. The Company believes that consumer credit risk, as assessed by the industry-wide FICO scoring method, is a relevant credit quality indicator. Borrower-specific FICO scores are obtained at origination as part of the Company’s formal underwriting process, and refreshed FICO scores are obtained by the Company at least quarterly.
For government-guaranteed loans, the Company monitors the credit quality based primarily on delinquency status, as it is a more relevant indicator of credit quality due to the government guarantee. At December 31, 2015 and 2014, 31% and 28%, respectively, of the guaranteed residential loan portfolio was current with respect to payments. At December 31, 2015 and 2014, 78% and 79%, respectively, of the guaranteed student loan portfolio was current with respect to payments. The Company's loss exposure on guaranteed residential and student loans is mitigated by the government guarantee.

Impaired Loans
A loan is considered impaired when it is probable that the Company will be unable to collect all amounts due, including principal and interest, according to the contractual terms of the agreement. Commercial nonaccrual loans greater than $3 million and certain commercial, residential, and consumer loans whose terms have been modified in a TDR are individually evaluated for impairment. Smaller-balance homogeneous loans that are collectively evaluated for impairment are not included in the following tables. Additionally, the tables below exclude guaranteed consumer student loans and guaranteed residential mortgages for which there was nominal risk of principal loss.

1 Nonaccruing restructured loans are included in total nonaccrual/NPLs.
2 Does not include foreclosed real estate related to loans insured by the FHA or the VA. Proceeds due from the FHA and the VA are recorded as a receivable in other assets in the Consolidated Balance Sheets until the property is conveyed and the funds are received. The receivable related to proceeds due from the FHA or the VA totaled $52 million and $57 million at December 31, 2015 and 2014, respectively.



The Company's recorded investment of nonaccruing loans secured by residential real estate properties for which formal foreclosure proceedings are in process at December 31, 2015 and 2014 was $112 million and $152 million, respectively. The Company's recorded investment of accruing loans secured by residential real estate properties for which formal foreclosure proceedings are in process at December 31, 2015 and 2014 was $152 million and $194 million, of which $141 million and $179 million were insured by the FHA or the VA, respectively.
At December 31, 2015 and 2014, OREO was comprised of $39 million and $75 million of foreclosed residential real estate properties and $11 million and $16 million of foreclosed commercial real estate properties, respectively, with the remainder related to land and other properties.


Restructured Loans
A TDR is a loan for which the Company has granted an economic concession to the borrower, in response to certain instances of financial difficulty experienced by the borrower that the Company would not have otherwise considered. When a loan is modified under the terms of a TDR, the Company typically offers the borrower an extension of the loan maturity date and/or a reduction in the original contractual interest rate. In certain situations, the Company may offer to restructure a loan in a manner that ultimately results in the forgiveness of a contractually specified principal balance.
At December 31, 2015 and 2014, the Company had $4 million and $1 million, respectively, of commitments to lend additional funds to debtors whose terms have been modified in a TDR. The number and amortized cost of loans modified under the terms of a TDR by type of modification are shown in the following tables.

Concentrations of Credit Risk
The Company does not have a significant concentration of risk to any individual client except for the U.S. government and its agencies. However, a geographic concentration arises because the Company operates primarily within Florida, Georgia, Maryland, North Carolina, South Carolina, Tennessee, Virginia, and the District of Columbia. The Company engages in limited international banking activities. The Company’s total cross-border outstanding loans were $1.6 billion and $1.3 billion at December 31, 2015 and 2014, respectively.
With respect to collateral concentration, at December 31, 2015, the Company owned $38.9 billion in loans secured by residential real estate, representing 29% of total LHFI. Additionally, the Company had $10.5 billion in commitments to extend credit on home equity lines and $3.2 billion in mortgage loan commitments at December 31, 2015. At December 31, 2014, the Company owned $38.8 billion in loans secured by residential real estate, representing 29% of total LHFI, and had $10.9 billion in commitments to extend credit on home equity lines and $3.3 billion in mortgage loan commitments. At both December 31, 2015 and December 31, 2014, 2% of residential loans owned were guaranteed by a federal agency or a GSE.
The following table presents loans in the residential mortgage portfolio that included a high original LTV ratio (in excess of 80%), an interest only feature, and/or a second lien position that may increase the Company’s exposure to credit risk and result in a concentration of credit risk. At December 31, 2015 and December 31, 2014, borrowers' current weighted average FICO score on these loans was 745 and 738, respectively.

As discussed in Note 1, “Significant Accounting Policies,” the ALLL is composed of both specific allowances for certain nonaccrual loans and TDRs and general allowances grouped into loan pools based on similar characteristics. No allowance is required for loans measured at fair value. Additionally, the Company records an immaterial allowance for loan products that are guaranteed by government agencies, as there is nominal risk of principal loss. The Company’s LHFI portfolio and related ALLL is presented in the following tables.

None of the Company's premises and equipment was subject to mortgage indebtedness (included in long-term debt) at December 31, 2015. At December 31, 2014, premises and equipment subject to mortgage indebtedness was immaterial. Net premises and equipment included $3 million and $4 million related to net capital leases at December 31, 2015 and 2014, respectively. Aggregate rent expense (principally for offices), including contingent rent expense and sublease income, totaled $200 million, $206 million, and $220 million for the years ended December 31, 2015, 2014, and 2013, respectively. Depreciation and amortization expense for the years ended December 31, 2015, 2014, and 2013 totaled $175 million, $176 million, and $185 million, respectively.
The Company previously completed sale leaseback transactions consisting of branch properties and various individual office buildings. Upon completion of these transactions, the Company recognized a portion of the resulting gains and deferred the remainder to be recognized ratably over the expected term of the lease, predominantly 10 years, as an offset to net occupancy expense. To the extent that terms on these leases are extended, the remaining deferred gain would be amortized over the new lease term. Amortization of deferred gains on sale leaseback transactions was $54 million, $53 million, and $58 million for the years ended December 31, 2015, 2014, and 2013, respectively. At December 31, 2015 and 2014, the remaining deferred gain associated with sale leaseback transactions was $108 million and $162 million, respectively.
The Company has various obligations under capital leases and noncancelable operating leases for premises and equipment. The leases predominantly expire over the next 10 years, with the longest expiring in 2081. Many of these leases provide for periodic adjustment of rentals based on changes in various economic indicators, while others also include a renewal option.
The following table presents future minimum payments under noncancelable operating leases, net of sublease rentals, with initial terms in excess of one year at December 31, 2015. Capital leases were immaterial at December 31, 2015.

Goodwill and Other Intangible Assets
Goodwill and Other Intangible Assets
NOTE 9 – GOODWILL AND OTHER INTANGIBLE ASSETS
Goodwill
The Company conducts a goodwill impairment test at the reporting unit level at least annually, or more frequently as events occur or circumstances change that would more-likely-than-not reduce the fair value of a reporting unit below its carrying amount. In the third quarter of 2015, the Company elected to prospectively change the date of its annual goodwill impairment test from September 30 to October 1 to better align the timing of the test with the availability of key inputs.
The Company performed goodwill impairment analyses for its Wholesale Banking reporting unit as of October 1, 2015, September 30, 2015, December 31, 2014, and September 30, 2014, as well as for its Consumer Banking and Private Wealth Management reporting unit as of October 1, 2015, September 30, 2015, and September 30, 2014. Based on the results of the impairment analyses, the Company concluded that the fair values of the reporting units exceeded their respective carrying values; therefore, there was no goodwill impairment. The Company monitored events and circumstances during the fourth quarter of 2015 and did not observe any factors that would more-likely-than-not reduce the fair value of a reporting unit below its respective carrying value. See Note 1, "Significant Accounting Policies," for additional information regarding the Company's goodwill accounting policy.
There were no changes in the carrying amount of goodwill by reportable segment for the year ended December 31, 2015. Changes in the carrying amount of goodwill by reportable segment for the year ended December 31, 2014 are presented in the following table.

The Company's estimated future amortization of intangible assets subject to amortization was immaterial at December 31, 2015.

Servicing Rights
The Company retains servicing rights for certain of its sales or securitizations of residential mortgage and consumer indirect loans. MSRs on residential mortgage loans and servicing rights on consumer indirect loans are the only servicing assets capitalized by the Company and are classified within other intangible assets on the Company's Consolidated Balance Sheets.

Mortgage Servicing Rights
Income earned by the Company on its MSRs is derived primarily from contractually specified mortgage servicing fees and late fees, net of curtailment costs. Such income earned for the year ended December 31, 2015, 2014, and 2013 was $347 million, $329 million, and $317 million, respectively. These amounts are reported in mortgage servicing related income in the Consolidated Statements of Income.
At December 31, 2015 and 2014, the total UPB of mortgage loans serviced was $148.2 billion and $142.1 billion, respectively. Included in these amounts were $121.0 billion and $115.5 billion at December 31, 2015 and 2014, respectively, of loans serviced for third parties. The Company purchased MSRs on residential loans with a UPB of $10.3 billion during the year ended December 31, 2015, all of which are reflected in the UPB amounts above. The Company purchased MSRs on residential loans with a UPB of $10.9 billion during the year ended December 31, 2014. During the years ended December 31, 2015 and 2014, the Company sold MSRs on residential loans, at a price approximating their fair value, with a UPB of $803 million and $878 million, respectively.
The Company calculates the fair value of MSRs using a valuation model that calculates the present value of estimated future net servicing income using prepayment projections, spreads, and other assumptions. Senior management and the STM Valuation Committee review all significant assumptions at least quarterly, comparing these inputs to various sources of market data. Changes to valuation model inputs are reflected in the periods' results. See Note 18, “Fair Value Election and Measurement,” for further information regarding the Company's MSR valuation methodology.
A summary of the key inputs used to estimate the fair value of the Company’s MSRs at December 31, 2015 and 2014, and the sensitivity of the fair values to immediate 10% and 20% adverse changes in those inputs, are presented in the following table.

These MSR sensitivities are hypothetical and should be used with caution. Changes in fair value based on variations in assumptions generally cannot be extrapolated because (i) the relationship of the change in an assumption to the change in fair value may not be linear and (ii) changes in one assumption may result in changes in another, which might magnify or counteract the sensitivities. The sensitivities do not reflect the effect of hedging activity undertaken by the Company to offset changes in the fair value of MSRs. See Note 17, “Derivative Financial Instruments,” for further information regarding these hedging activities.

Consumer Loan Servicing Rights
In June 2015, the Company completed the securitization of $1.0 billion of indirect auto loans, with servicing rights retained, and recognized a $13 million servicing asset at the time of sale. See Note 10, “Certain Transfers of Financial Assets and Variable Interest Entities,” for additional information on the Company's securitization transactions.
Income earned by the Company on its consumer loan servicing rights is derived primarily from contractually specified servicing fees and other ancillary fees. Such income earned for the year ended December 31, 2015 was $5 million, and is reported in other noninterest income in the Consolidated Statements of Income. There was no income earned on consumer loan servicing rights for the years ended December 31, 2014 and 2013.
At December 31, 2015, the total UPB of consumer indirect loans serviced was $807 million, all of which were serviced for third parties. No consumer loan servicing rights were purchased or sold during the years ended December 31, 2015 and 2014.
Consumer loan servicing rights are accounted for at amortized cost and are monitored for impairment on an ongoing basis. The Company calculates the fair value of consumer servicing rights using a valuation model that calculates the present value of estimated future net servicing income using prepayment projections and other assumptions. Impairment, if any, is recognized when changes in valuation model inputs reflect a fair value for the servicing asset that is below its respective carrying value. At December 31, 2015, both the amortized cost and the fair value of the Company's consumer loan servicing rights were $9 million.
Certain Transfers of Financial Assets and Variable Interest Entities
Transfers and Servicing of Financial Assets [Text Block]
NOTE 10 - CERTAIN TRANSFERS OF FINANCIAL ASSETS AND VARIABLE INTEREST ENTITIES
The Company has transferred loans and securities in sale or securitization transactions in which the Company retains certain beneficial interests or retains servicing rights. Cash receipts on beneficial interests held related to these transfers were $19 million, $21 million, and $36 million for the years ended December 31, 2015, 2014, and 2013, respectively. The servicing fees related to these asset transfers (excluding servicing fees for residential mortgage loan transfers to GSEs, which are discussed in Note 9, “Goodwill and Other Intangible Assets”) were immaterial for each of the years ended December 31, 2015, 2014, and 2013.
When a transfer or other transaction occurs with a VIE, the Company first determines whether it has a VI in the VIE. A VI is typically in the form of securities representing retained interests in transferred assets and, at times, servicing rights and collateral management fees. When determining whether to consolidate the VIE, the Company evaluates whether it has both (i) the power to direct the activities that most significantly impact the economic performance of the VIE, and (ii) the obligation to absorb losses, or the right to receive benefits, that could potentially be significant to the VIE.
To determine whether a transfer should be accounted for as a sale or a secured borrowing, the Company evaluates whether: (i) the transferred assets are legally isolated, (ii) the transferee has the right to pledge or exchange the transferred assets, and (iii) the Company has relinquished effective control of the transferred assets. If all three conditions are met, then the transfer is accounted for as a sale.
Except as specifically noted herein, the Company is not required to provide additional financial support to any of the entities to which the Company has transferred financial assets, nor has the Company provided any support it was not otherwise obligated to provide. No events occurred during the year ended December 31, 2015 that changed the Company’s previous conclusions regarding whether it is the primary beneficiary of the VIEs described herein. Furthermore, no events occurred during the year ended December 31, 2015 that changed the Company’s sale conclusion with regards to previously transferred residential mortgage loans, indirect auto loans, student loans, or commercial and corporate loans.
Transfers of Financial Assets
The following discussion summarizes transfers of financial assets to VIEs for which the Company has retained some level of continuing involvement.
Residential Mortgage Loans
The Company typically transfers first lien residential mortgage loans in conjunction with Ginnie Mae, Fannie Mae, and Freddie Mac securitization transactions, whereby the loans are exchanged for cash or securities that are readily redeemable for cash, and servicing rights are retained.
The Company sold residential mortgage loans to the aforementioned GSEs, which resulted in pre-tax net gains of $232 million, $224 million, and $186 million for the years ended December 31, 2015, 2014, and 2013, respectively. The Company has made certain representations and warranties with respect to the transfer of these loans. See Note 16, “Guarantees,” for additional information regarding representations and warranties.
In a limited number of securitizations, the Company has received securities in addition to cash in exchange for the transferred loans, while also retaining servicing rights. The securities received are measured at fair value and classified as securities AFS. At December 31, 2015 and 2014, the fair value of securities received totaled $38 million and $55 million, respectively.
The Company evaluated its VI securitization entities for potential consolidation under the VIE consolidation model. Notwithstanding the Company's role as servicer, the Company typically does not have power over the securitization entities as a result of rights held by the master servicer. However, in certain transactions, the Company does have power as the servicer, but does not have an obligation to absorb losses, or the right to receive benefits, that could potentially be significant. In all such cases, the Company does not consolidate the securitization entity. Total assets at December 31, 2015 and 2014, of the unconsolidated entities in which the Company has a VI were $241 million and $288 million, respectively.
The Company’s maximum exposure to loss related to these unconsolidated residential mortgage loan securitizations is comprised of the loss of value of any interests it retains, which are immaterial, and any repurchase obligations or other losses it incurs as a result of any guarantees related to these securitizations, discussed further in Note 16, “Guarantees.”
Commercial and Corporate Loans
The Company holds securities issued by CLO entities that own commercial leveraged loans and bonds, certain of which were transferred to the entities by the Company. The Company has determined that the CLO entities are VIEs and that it is not the primary beneficiary of these entities because it does not possess the power to direct the activities that most significantly impact the economic performance of the entities. The Company previously acted as collateral manager for one of these CLO entities that it consolidated; however, upon the sale of RidgeWorth in May 2014, the Company was no longer the collateral manager or primary beneficiary of this CLO and the CLO was deconsolidated. At December 31, 2015 and 2014, the Company's unconsolidated VIEs had estimated assets of $525 million and $704 million and estimated liabilities of $482 million and $654 million, respectively. At December 31, 2015 and 2014, the Company's holdings included a preference share exposure valued at $2 million and $3 million, and a senior debt exposure valued at $8 million and $18 million, respectively.

Consumer Loans
Guaranteed Student Loans
The Company has securitized government-guaranteed student loans through a transfer of loans to a securitization entity and retained the residual interest in the entity. The Company concluded that this entity should be consolidated because the Company has (i) the power to direct the activities that most significantly impact the economic performance of the VIE and (ii) the obligation to absorb losses, and the right to receive benefits, that could potentially be significant. At December 31, 2015 and 2014, the Company’s Consolidated Balance Sheets reflected $262 million and $306 million of assets held by the securitization entity and $259 million and $302 million of debt issued by the entity, respectively.
To the extent that the securitization entity incurs losses on its assets, the securitization entity has recourse to the guarantor of the underlying loan, which is backed by the Department of Education up to a maximum guarantee of 100%. When the maximum government guarantee is not realized, losses reduce the amount of available cash payable to the Company as the owner of the residual interest. To the extent that losses result from a breach of servicing responsibilities, the securitization entity has recourse to the Company, which functions as the master servicer, whereby the Company may be required to repurchase the defaulting loan(s) at par value. If the breach was caused by the subservicer, the Company would seek reimbursement from the subservicer up to the guaranteed amount. The Company’s maximum exposure to loss related to the securitization entity would arise from a breach of its servicing responsibilities. To date, loss claims filed with the guarantor that have been denied due to servicing errors have either been, or are in the process of, being cured, or reimbursement has been provided to the Company by the subservicer, or in limited cases, absorbed by the Company.
Indirect Auto Loans
In June 2015, the Company transferred indirect auto loans to a securitization entity, which was determined to be a VIE, and accounted for the transfer as a sale. The Company retained servicing rights for the transferred loans, but did not retain any debt or equity interest in the securitization entity. While the Company has the power to direct the activities that most significantly impact the economic performance of the VIE through its servicing rights, it was determined that this entity should not be consolidated since the Company does not have the obligation to absorb losses, or the right to receive benefits, that could potentially be significant to the VIE.
At the time of the transfer, the UPB of the transferred loans was $1.0 billion and the consideration received was $1.0 billion, resulting in an immaterial pre-tax loss for the year ended December 31, 2015, which was recorded in other noninterest income in the Consolidated Statements of Income. See Note 9, "Goodwill and Other Intangible Assets," for additional information regarding the servicing asset recognized in this transaction.
To the extent that losses on the transferred loans are the result of a breach of representations and warranties related to either the initial transfer or the Company's ongoing servicing responsibilities, the securitization entity has recourse to the Company whereby the Company may be obligated to either cure the breach or repurchase the affected loans. The Company’s maximum exposure to loss related to the loans transferred to the securitization entity would arise from a breach of representations and warranties and/or a breach of the Company's servicing obligations. Potential losses suffered by the securitization entity that the Company may be liable for are limited to approximately $1.0 billion, which is the total of the initial UPB of transferred loans and the carrying value of the servicing asset.
The Company's total managed loans, including the LHFI portfolio and other securitized and unsecuritized loans, are presented in the following table by portfolio balance and delinquency (accruing loans 90 days or more past due and all nonaccrual loans) at December 31, 2015 and 2014, as well as the related net charge-offs for the years ended December 31, 2015 and 2014.

Other Variable Interest Entities
In addition to exposure to VIEs arising from transfers of financial assets, the Company also has involvement with VIEs from other business activities.
Total Return Swaps
The Company facilitates matched book TRS transactions on behalf of clients, whereby a VIE purchases reference assets identified by a client and the Company enters into a TRS with the VIE, with a mirror-image TRS facing the client. The TRS contract between the VIE and the Company hedges the Company’s exposure to the TRS contract with its third party client. The Company provides senior financing to the VIE, in the form of demand notes to fund the purchase of the reference assets. The TRS contracts pass through interest and other cash flows on the reference assets to the third party clients, along with exposing those clients to decreases in value on the assets and providing them with the rights to appreciation on the assets. The terms of the TRS contracts require the third parties to post initial margin collateral, in addition to ongoing margin as the fair values of the underlying assets change.
The Company evaluated the related VIEs for consolidation, noting that the Company and its third party clients are VI holders. The Company evaluated the nature of all VIs and other interests and involvement with the VIEs, in addition to the purpose and design of the VIEs, relative to the risks they were designed to create. The VIEs were designed for the benefit of the third parties and would not exist if the Company did not enter into the TRS contracts on their behalf. The activities of the VIEs are restricted to buying and selling the reference assets and the risks/benefits of any such assets owned by the VIEs are passed to the third party clients via the TRS contracts. The Company determined that it is not the primary beneficiary of the VIEs, as the design of its matched book TRS business results in the Company having no substantive power to direct the significant activities of the VIEs, and therefore, the VIEs are not consolidated.
The outstanding notional amounts of the VIE-facing TRS contracts and the Company's related senior financing outstanding to VIEs were $2.2 billion and $2.3 billion at December 31, 2015 and 2014, respectively. These financings were classified within trading assets and derivative instruments on the Consolidated Balance Sheets and were measured at fair value. The Company entered into client-facing TRS contracts of the same outstanding notional amounts. The notional amounts of the TRS contracts with VIEs represent the Company’s maximum exposure to loss, although this exposure has been mitigated via the TRS contracts with third parties. For additional information on the Company’s TRS contracts and its involvement with these VIEs, see Note 17, “Derivative Financial Instruments.”
Community Development Investments
As part of its community reinvestment initiatives, the Company invests in multi-family affordable housing developments and other community development entities as a limited and/or general partner and/or a debt provider. The Company receives tax credits for its limited partner investments. The Company has determined that the vast majority of the related partnerships are VIEs.
In limited circumstances, the Company owns both the limited partner and general partner interests, in which case the related partnerships are not considered VIEs and are consolidated by the Company. The Company sold properties with a carrying value of $72 million for gains of $19 million during the year ended December 31, 2015, and the remaining properties held for sale at December 31, 2015 were immaterial. One property was sold during the year ended December 31, 2014 for an immaterial gain. During 2013, the Company sold properties resulting in an aggregate gain of $17 million.
The Company has concluded that it is not the primary beneficiary of affordable housing partnerships when it invests as a limited partner and there is a third party general partner. The investments are accounted for in accordance with the accounting guidance for investments in affordable housing projects. The general partner, or an affiliate of the general partner, often provides guarantees to the limited partner, which protects the Company from construction and operating losses and tax credit allocation deficits. Assets of $1.6 billion and $1.4 billion in these and other community development partnerships were not included in the Consolidated Balance Sheets at December 31, 2015 and 2014, respectively. The Company's limited partner interests had carrying values of $672 million and $363 million at December 31, 2015 and 2014, respectively, and are recorded in other assets on the Company’s Consolidated Balance Sheets. The Company’s maximum exposure to loss for these investments totaled $1.1 billion and $776 million at December 31, 2015 and 2014, respectively. The Company’s maximum exposure to loss would result from the loss of its limited partner investments along with $268 million and $278 million of loans, interest-rate swap fair value exposures, or letters of credit issued by the Company to the entities at December 31, 2015 and 2014, respectively. The remaining exposure to loss is primarily attributable to unfunded equity commitments that the Company is required to fund if certain conditions are met.
The Company also owns noncontrolling interests in funds whose purpose is to invest in community developments. At December 31, 2015 and 2014, the Company's investment in these funds totaled $132 million and $113 million, respectively, and the Company's maximum exposure to loss on its equity investments, which is comprised of its investments in the funds plus any additional unfunded equity commitments, was $321 million and $236 million, respectively.
During the year ended December 31, 2015, 2014, and 2013, the Company recognized $68 million, $66 million, and $64 million of tax credits for qualified affordable housing projects, and $66 million, $61 million, and $49 million of amortization on qualified affordable housing projects in the provision for income taxes, respectively.
During the year ended December 31, 2015, the Company recorded $35 million of expense related to community development investments not within the scope of the accounting guidance for investments in qualified affordable housing projects. During the year ended December 31, 2014, the Company recorded $19 million of amortization related to these non-qualified investments ($5 million of which was recorded within other noninterest expense and $14 million was recorded within amortization expense in the Company's Consolidated Statements of Income). No amortization was recorded for these non-qualified investments during the year ended December 31, 2013.

During 2015, the Bank terminated $3.8 billion of FHLB advances. These early terminations were related to a repositioning of the balance sheet and resulted in the recognition of $24 million in debt extinguishment costs, net of related hedges, recorded in other noninterest expense in the Consolidated Statement of Income. Additionally during 2015, $1.0 billion of the Bank's long-term FHLB advances matured and another $1.2 billion were added. Furthermore, the Bank had variable rate and fixed rate subordinated debt of $500 million and $269 million, respectively, that matured during 2015. The Company had no additional material issuances, advances, repurchases, terminations, or extinguishments of long-term debt during the year.
Restrictive provisions of several long-term debt agreements prevent the Company from creating liens on, disposing of, or issuing (except to related parties) voting stock of subsidiaries. Furthermore, there are restrictions on mergers, consolidations, certain leases, sales or transfers of assets, minimum shareholders’ equity, and maximum borrowings by the Company. At December 31, 2015, the Company was in compliance with all covenants and provisions of long-term debt agreements.
As currently defined by federal bank regulators, long-term debt of $157 million and $627 million qualified as Tier 1 capital at December 31, 2015 and 2014, and long-term debt of $1.0 billion and $792 million qualified as Tier 2 capital at December 31, 2015 and 2014, respectively. Beginning January 1, 2016, the long-term debt that qualified as Tier 1 capital at December 31, 2015 will be completely phased-out of Tier 1 capital and will be classified as Tier 2 capital, using the methodology specified under Basel III. See Note 13, "Capital," for additional information regarding regulatory capital adequacy requirements for the Company and the Bank.
The Company does not consolidate certain wholly-owned trusts which were formed for the sole purpose of issuing trust preferred securities. The proceeds from the trust preferred securities issuances were invested in junior subordinated debentures of the Parent Company. The obligations of these debentures constitute a full and unconditional guarantee by the Parent Company of the trust preferred securities.

Contractual Commitments
In the normal course of business, the Company enters into certain contractual commitments. These commitments include obligations to make future payments on lease agreements, contractual commitments for capital expenditures, and service contracts.
The following table presents the Company's significant contractual commitments at December 31, 2015, except for long-term debt, operating leases, and pension and other postretirement benefit plans. Information on those obligations is included above, in Note 8, "Premises and Equipment," and in Note 15, "Employee Benefit Plans." Capital lease obligations and foreign time deposits were immaterial at December 31, 2015 and are not presented in the table.

Capital
Regulatory Capital Requirements under Banking Regulations [Text Block]
NOTE 13 – CAPITAL
During 2015, pursuant to the Federal Reserve's non-objection to the Company's capital plan in conjunction with the 2015 CCAR, the Company increased its quarterly common stock dividend from $0.20 to $0.24 per share beginning in the second quarter of 2015, maintained dividend payments on its preferred stock, and repurchased $525 million of its outstanding common stock at market value (approximately 12.7 million shares) under the 2015 plan. During the first quarter of 2015, the Company also repurchased $115 million of its outstanding common stock at market value, which completed the repurchase of shares pursuant to its 2014 CCAR capital plan, which effectively expired on March 31, 2015. At December 31, 2015, the Company had capacity under its 2015 capital plan to purchase an additional $350 million of its outstanding common stock through June 30, 2016. In December 2015, the Company repurchased an additional $39 million of its outstanding common stock at market value, which was incremental to and separate from the existing availability under the 2015 CCAR capital plan.
During the years ended December 31, 2015, 2014, and 2013, the Company declared and paid common dividends of $475 million, or $0.92 per common share, $371 million, or $0.70 per common share, and $188 million, or $0.35 per common share, respectively. The Company also recognized dividends on perpetual preferred stock of $64 million, $42 million, and $37 million during the years ended December 31, 2015, 2014, and 2013, respectively. During 2015, both the Series A and Series B Perpetual Preferred Stock dividend was $4,056 per share, the Series E Perpetual Preferred Stock dividend was $5,875 per share, and the Series F Perpetual Preferred Stock dividend was $6,219 per share.
The Company remains subject to certain restrictions on its ability to increase the dividend on common shares as a result of participating in the U.S. Treasury’s CPP. If the Company increases its dividend above $0.54 per share per quarter prior to the tenth anniversary of its participation in the CPP, then the anti-dilution provision within the warrants issued in connection with the Company’s participation in the CPP will require the exercise price and number of shares to be issued upon exercise to be proportionately adjusted. The amount of such adjustment is determined by a formula and depends in part on the extent to which the Company raises its dividend. The formulas are contained in the warrant agreements which were filed as exhibits to Form 8-K filed on September 23, 2011.
Substantially all of the Company’s retained earnings are undistributed earnings of the Bank, which are restricted by various regulations administered by federal and state bank regulatory authorities. At December 31, 2015 and 2014, retained earnings of the Bank available for payment of cash dividends to the Parent Company under these regulations totaled approximately $2.7 billion and $2.9 billion, respectively. Additionally, the Federal Reserve requires the Company to maintain cash reserves. At December 31, 2015 and 2014, these reserve requirements totaled $1.0 billion and $1.5 billion, respectively, and were fulfilled with a combination of cash on hand and deposits at the Federal Reserve.

1 Basel III Final Rules became effective on January 1, 2015; thus, CET1 is not applicable ("N/A") in periods ending prior to January 1, 2015 and Basel I Tier 1 common equity is N/A in periods ending after January 1, 2015. Tier 1 capital, Total capital, and Leverage ratio for periods ended prior to January 1, 2015 were calculated under Basel I.

On October 11, 2013, the Federal Reserve published final rules in the Federal Register implementing Basel III. These rules, which became effective for the Company and the Bank on January 1, 2015, include the following minimum capital requirements: CET1 ratio of 4.5%; Tier 1 capital ratio of 6%; Total capital ratio of 8%; Leverage ratio of 4%; and a capital conservation buffer of 2.5% of RWA. The capital conservation buffer is applicable beginning on January 1, 2016 and will be phased-in through December 31, 2018.
At December 31, 2015, the Company had $627 million in principal amount of trust preferred securities outstanding. The Basel III rules require the phase-out of non-qualifying Tier 1 capital instruments such as trust preferred securities. Accordingly, on January 1, 2015, the Company began phasing-out of Tier 1 capital its trust preferred and other hybrid capital securities, and instead began treating them as qualifying Tier 2 capital. Beginning January 1, 2016, these securities will be completely phased-out of Tier 1 capital and will be classified as Tier 2 capital, using the methodology specified under Basel III.

In September 2006, the Company authorized and issued depositary shares representing ownership interests in 5,000 shares of Perpetual Preferred Stock, Series A, no par value and $100,000 liquidation preference per share (the Series A Preferred Stock). The Series A Preferred Stock has no stated maturity and will not be subject to any sinking fund or other obligation of the Company. Dividends on the Series A Preferred Stock, if declared, will accrue and be payable quarterly at a rate per annum equal to the greater of three-month LIBOR plus 0.53%, or 4.00%. Dividends on the shares are noncumulative. Shares of the Series A Preferred Stock have priority over the Company’s common stock with regard to the payment of dividends and, as such, the Company may not pay dividends on or repurchase, redeem, or otherwise acquire for consideration shares of its common stock unless dividends for the Series A Preferred Stock have been declared for that period and sufficient funds have been set aside to make payment. During 2009, the Company repurchased 3,275 shares of the Series A Preferred Stock. In September 2011, the Series A Preferred Stock became redeemable at the Company’s option at a redemption price equal to $100,000 per share, plus any declared and unpaid dividends. Except in certain limited circumstances, the Series A Preferred Stock does not have any voting rights.
In December 2011, the Company authorized 5,010 shares and issued 1,025 shares of Perpetual Preferred Stock, Series B, no par value and $100,000 liquidation preference per share (the Series B Preferred Stock). The Series B Preferred Stock has no stated maturity and will not be subject to any sinking fund or other obligation of the Company. Dividends on the shares are noncumulative and, if declared, will accrue and be payable quarterly at a rate per annum equal to the greater of three-month LIBOR plus 0.65%, or 4.00%. Shares of the Series B Preferred Stock have priority over the Company's common stock with regard to the payment of dividends and, as such, the Company may not pay dividends on or repurchase, redeem, or otherwise acquire for consideration shares of its common stock unless dividends for the Series B Preferred Stock have been declared for that period and sufficient funds have been set aside to make payment. The Series B Preferred Stock was immediately redeemable upon issuance at the Company's option at a redemption price equal to $100,000 per share, plus any declared and unpaid dividends. Except in certain limited circumstances, the Series B Preferred Stock does not have any voting rights.
In December 2012, the Company authorized 5,000 shares and issued 4,500 shares of Perpetual Preferred Stock, Series E, no par value and $100,000 liquidation preference per share (the Series E Preferred Stock). The Series E Preferred Stock has no stated maturity and will not be subject to any sinking fund or other obligation of the Company to redeem, repurchase, or retire the shares. Dividends on the shares are noncumulative and, if declared, will accrue and be payable quarterly at a rate per annum of 5.875%. Shares of the Series E Preferred Stock have priority over the Company's common stock with regard to the payment of dividends and rank equally with the Company's outstanding Perpetual Preferred Stock, Series A and Series B and, as such, the Company may not pay dividends on or repurchase, redeem, or otherwise acquire for consideration shares of its common stock unless dividends for the Series E Preferred Stock have been declared for that period and sufficient funds have been set aside to make payment. The Series E Preferred Stock is redeemable, at the option of the Company, on any dividend payment date occurring on or after March 15, 2018, at a redemption price equal to $100,000 per share, plus any declared and unpaid dividends, without regard to any undeclared dividends. Except in certain limited circumstances, the Series E Preferred Stock does not have any voting rights.
In November 2014, the Company issued depositary shares representing ownership interest in 5,000 shares of Perpetual Preferred Stock, Series F, with no par value and $100,000 liquidation preference per share (the "Series F Preferred Stock"). As a result of this issuance, the Company received net proceeds of $496 million after the underwriting discount, but before expenses, and used the net proceeds for general corporate purposes. The Series F Preferred Stock has no stated maturity and will not be subject to any sinking fund or other obligation of the Company to redeem, repurchase, or retire the shares. Dividends for the shares are noncumulative and, if declared, will be payable semi-annually beginning on June 15, 2015 through December 15, 2019 at a rate per annum of 5.625%, and payable quarterly beginning on March 15, 2020 at a rate per annum equal to the three-month LIBOR plus 3.86%. By its terms, the Company may redeem the Series F Preferred Stock on any dividend payment date occurring on or after December 15, 2019 or at any time within 90 days following a regulatory capital event, at a redemption price of $100,000 per share plus any declared and unpaid dividends. Except in certain limited circumstances, the Series F Preferred Stock does not have any voting rights.
In 2008, the Company issued to the U.S. Treasury as part of the CPP, Series C and D Fixed Rate Cumulative Perpetual Preferred Stock and Series A and B warrants to purchase a total of 17.9 million shares of the Company's common stock. The Series A warrants entitle the holder to purchase 6 million shares of the Company's common stock at an exercise price of $33.70 per share, while the Series B warrants entitle the holder to purchase 11.9 million shares of the Company's common stock at an exercise price of $44.15 per share. The Series A and B warrants have expiration dates of December 2018 and November 2018, respectively.
In March 2011, the Company repurchased its Series C and D Preferred Stock from the U.S. Treasury. In September 2011, the U.S. Treasury held a public auction to sell the warrants to purchase the 17.9 million shares of the Company's common stock. In conjunction with the U.S. Treasury's auction, the Company acquired 4 million of the stock purchase warrants, Series A, for $11 million, which were then retired.
At December 31, 2015, 13.9 million warrants remained outstanding and the Company had authority from its Board to repurchase all of these outstanding stock purchase warrants; however, any such repurchase would be subject to the non-objection of the Federal Reserve through the capital planning and stress testing process.

The DTAs include state NOLs and other state carryforwards that will expire, if not utilized, in varying amounts from 2016 to 2035. At December 31, 2015 and 2014, the Company had a valuation allowance recorded against its state carryforwards and certain state DTAs of $79 million and $98 million, respectively. The decrease in the valuation allowance was primarily due to a decrease in the valuation allowance recorded against STM's state NOLs. A valuation allowance is not required for the federal and the remaining state DTAs because the Company believes it is more-likely-than-not that these assets will be realized.

The amount of UTBs that would favorably affect the Company's effective tax rate, if recognized, was $67 million at December 31, 2015.
Interest related to UTBs is recorded in the provision for income taxes. The Company had a gross liability of $8 million and $20 million for interest related to its UTBs at December 31, 2015 and 2014, respectively. During the years ended December 31, 2015 and 2014, the Company recognized a gross benefit of $4 million and expense of $3 million, respectively, for interest on the UTBs.
The Company files U.S. federal, state, and local income tax returns. The Company's federal income tax returns are no longer subject to examination by the IRS for taxable years prior to 2010. With limited exceptions, the Company is no longer subject to examination by state and local taxing authorities for taxable years prior to 2006. It is reasonably possible that the liability for UTBs could decrease by as much as $17 million during the next 12 months due to completion of tax authority examinations and the expiration of statutes of limitations. It is uncertain how much, if any, of this potential decrease will impact the Company’s effective tax rate.
Employee Benefit Plans
Employee Benefit Plans
NOTE 15 - EMPLOYEE BENEFIT PLANS
The Company sponsors various short-term incentive and LTI plans for eligible employees, which may be delivered through various programs, such as RSUs, restricted stock, performance stock units, and AIP and LTI cash. All incentive awards are subject to clawback provisions. Awards for performance stock units vest over a period of three years and are paid in cash. AIP is the Company's short-term cash incentive plan for key employees that provides for potential annual cash awards based on the Company's performance and/or the achievement of business unit and individual performance objectives. Awards under the LTI cash plan generally cliff vest after three years from the date of the award and are paid in cash. Compensation expense for incentive plans with cash payouts was $245 million, $203 million, and $150 million for the years ended December 31, 2015, 2014, and 2013, respectively.
Stock-Based Compensation
The Company provides stock-based awards through the 2009 Stock Plan under which the Compensation Committee of the Board of Directors has the authority to grant stock options, stock appreciation rights, restricted stock, performance stock units, and RSUs to key employees of the Company. Award vesting may be conditional based upon individual, business unit, Company, and/or performance relative to peer group metrics.
As amended and restated effective January 1, 2014, following approval by the Compensation Committee of the Board, shareholders approved an amendment to the 2009 Stock Plan to remove the sub-limit on shares available for grant that may be issued as restricted stock or RSUs. Accordingly, all 17 million remaining authorized shares previously under the Plan became available for grant as stock options, stock appreciation rights, restricted stock, or RSUs. Prior to the amendment, only a portion of such shares were available to be granted as either restricted stock or RSUs. At December 31, 2015, approximately 16 million shares were available for grant.
Shares or units of restricted stock may be granted to employees and directors. Generally, grants to employees either cliff vest after three years or vest pro-rata annually over three years. Restricted stock grants may be subject to one or more criteria, including employment, performance, or other conditions as established by the Compensation Committee at the time of grant. Any shares of restricted stock that are forfeited will again become available for issuance under the Stock Plan. An employee or director has the right to vote the shares of restricted stock after grant until they are forfeited. Compensation cost for restricted stock and RSUs is generally equal to the fair market value of the shares on the grant date of the award and is amortized to compensation expense over the vesting period. Dividends are paid on awarded, unvested restricted stock.
The Company accrues and reinvests dividends in equivalent shares of SunTrust common stock for unvested RSU awards, which are paid out when the underlying RSU award vests. Generally, RSU awards are classified as equity. However, during 2012 there were 574,257 RSUs granted that were classified as a liability because the grant date had not been achieved as defined under U.S. GAAP. These awards were granted with a fair value of $21.67 per unit on the grant date. The balance of RSUs classified as a liability at December 31, 2015 and 2014 was $23 million and $21 million, respectively.
Consistent with the Company's 2014 decision to discontinue the issuance of stock options, no stock options were granted during the years ended December 31, 2015 and 2014. For options issued in 2013 the fair value of option grants was estimated on the date of grant using the Black-Scholes option pricing model based on the assumptions presented in the following table.

1 Assumptions are not applicable ("N/A") as the Company discontinued the issuance of stock options and no stock options were granted for the years ended December 31, 2015 and 2014.
The Company used the projected dividend to be paid as the dividend yield assumption. The expected stock price volatility represented the implied volatility of SunTrust stock. The risk-free interest rate was derived from the U.S. Treasury yield curve in effect at the time of grant based on the expected life of the option. The expected life of options represented the period of time that the stock options were expected to be outstanding and was derived from historical data that was used to evaluate patterns such as stock option exercise and employee termination.
Stock options were granted at an exercise price that was no less than the fair market value of a share of SunTrust common stock on the grant date and were either tax-qualified incentive stock options or non-qualified stock options. Stock options typically vest pro-rata over three years and generally have a maximum contractual life of ten years. Upon exercise, shares are generally issued from treasury stock. The weighted average fair value of options granted during year ended December 31, 2013 was $7.37 per share.

Retirement Plans
Noncontributory Pension Plans
The Company maintains a funded, noncontributory qualified retirement plan ("Retirement Plan") covering employees meeting certain service requirements. The plan provides benefits based on salary and years of service, and based on either a traditional pension benefit formula, a cash balance formula for the PPAs, or a combination of both. Participants are 100% vested after three years of service. The interest crediting rate applied to each PPA was 3.00% for 2015. The Company monitors the funding status of the plan closely and due to the current funded status, the Company did not make a contribution to its noncontributory qualified retirement plan for the 2015 plan year.
The Company also maintains unfunded, noncontributory nonqualified supplemental defined benefit pension plans that cover key executives of the Company (the "SERP", the "ERISA Excess Plan", and the "Restoration Plan"). The plans provide defined benefits based on years of service and salary.
The SunTrust Banks, Inc. Restoration Plan (“Restoration Plan”), effective January 1, 2011, is a nonqualified defined benefit cash balance plan designed to restore benefits to certain employees who are limited under provisions of the Internal Revenue Code and are not otherwise provided for under the ERISA Excess Plan. The benefit formula under the Restoration Plan is the same as what is used for PPAs under the Retirement Plan.
On October 1, 2004, the Company acquired NCF. Prior to the acquisition, NCF sponsored a funded qualified retirement plan ("NCF Retirement Plan") and an unfunded nonqualified retirement plan, and certain other postretirement health benefits plans for its employees ("NCF Retirement Plan"). Due to the current funding status of the NCF qualified Retirement Plan, the Company did not make a contribution for the 2015 plan year.
The Retirement Plan, the SERP, the ERISA Excess Plan, and the Restoration Plan were each amended on November 14, 2011 to cease all future benefit accruals. Additionally, the NCF Retirement Plan was amended to cease any adjustments for pay increases after December 31, 2011.

Other Postretirement Benefits
The Company provides certain health care and life insurance benefits (“Other Postretirement Benefits”) to retired employees. At the option of the Company, retirees may continue certain health and life insurance benefits if they meet specific age and service requirements at the time of retirement. The health care plans are contributory with participant contributions adjusted annually, and the life insurance plans are noncontributory. Certain retiree health benefits are funded in a Retiree Health Trust. Additionally, certain retiree life insurance benefits are funded in a VEBA. Effective April 1, 2014, the Company amended the plan which now requires retirees age 65 and older to enroll in individual Medicare supplemental plans. In addition, the Company will fund a tax-advantaged HRA to assist some retirees with medical expenses.

Plan Assumptions
Each year, the SBFC, which includes several members of senior management, reviews and approves the assumptions used in the year-end measurement calculations for each plan. The discount rate for each plan, used to determine the present value of future benefit obligations, is determined by matching the expected cash flows of each plan to a yield curve based on long-term, high quality fixed income debt instruments available as of the measurement date. A series of benefit payments projected to be paid by the plan is developed based on the most recent census data, plan provisions, and assumptions. The benefit payments at each future maturity date are discounted by the year-appropriate spot interest rates. The model then solves for the discount rate that produces the same present value of the projected benefit payments as generated by discounting each year’s payments by the spot interest rate.
On December 31, 2015, the Company refined the calculation of the service and interest cost components of net periodic benefit expense for pension and other postretirement benefit plans. Previously the Company estimated service and interest cost components utilizing a single weighted-average discount rate derived from the yield curve used to measure the benefit obligation at the beginning of the period. Under the refined method, the Company utilized a full yield curve approach to estimate these components by applying specific spot rates along the yield curve used in the determination of the benefit obligation to the relevant projected cash flows. The Company made this change to more closely match the projected benefit cash flows and the corresponding yield curve spot rates, and to provide a more precise measurement of service and interest costs. This change had no impact on the measurement of the Company’s total benefit obligations recorded at December 31, 2015 or any other prior period. The Company accounted for this service and interest cost methodology refinement as a change in estimate that is inseparable from a change in accounting principle, and, accordingly, will recognize its effect prospectively beginning in 2016.
Actuarial gains and losses are created when actual experience deviates from assumptions. The actuarial losses on plan assets generated within the pension plans during 2015 resulted primarily from asset experience. The actuarial losses on obligations generated within the pension plans during 2014 resulted primarily from lower interest rates.
The SBFC establishes investment policies and strategies and formally monitors the performance of the investments throughout the year. The Company’s investment strategy with respect to pension assets is to invest the assets in accordance with ERISA and related fiduciary standards. The long-term primary investment objectives for the pension plans are to provide a commensurate amount of long-term growth of principal and income in order to satisfy the pension plan obligations without undue exposure to risk in any single asset class or investment category. The objectives are accomplished through investments in equities, fixed income, and cash equivalents using a mix that is conducive to participation in a rising market while allowing for protection in a declining market. The portfolio is viewed as long-term in its entirety, avoiding decisions regarding short-term concerns and any single investment. Asset allocation, as a percent of the total market value of the total portfolio, is set with the target percentages and ranges presented in the investment policy statement. Rebalancing occurs on a periodic basis to maintain the target allocation, but normal market activity may result in deviations.
The basis for determining the overall expected long-term rate of return on plan assets considers past experience, current market conditions, and expectations on future trends. A building block approach is used that considers long-term inflation, real returns, equity risk premiums, target asset allocations, market corrections, and expenses. Capital market simulations from internal and external sources, survey data, economic forecasts, and actuarial judgment are all used in this process. The expected long-term rate of return for pension obligations is 6.68% for 2016.
The investment strategy for the other postretirement benefit plans is maintained separately from the strategy for the pension plans. The Company’s investment strategy is to create a series of investment returns sufficient to provide a commensurate amount of long-term principal and income growth in order to satisfy the other postretirement benefit plan's obligations. Assets are diversified among equity funds and fixed income investments according to the mix approved by the SBFC. Due to other postretirement benefits having a shorter time horizon, a lower equity profile is appropriate. The expected long-term rate of return for other postretirement benefits is 3.13% for 2016.

The Company sets pension asset values equal to their market value, reflecting gains and losses immediately rather than deferring over a period of years, which provides a more realistic economic measure of the plan’s funded status and cost. Assumed healthcare cost trend rates have a significant effect on the amounts reported for the other postretirement benefit plans. At December 31, 2015, the Company assumed that pre-65 retiree healthcare costs will increase at an initial rate of 7.25% per year. The Company expects this annual cost increase to decrease over a 9-year period to 5.00% per year. The effect of a 1% increase/decrease in the healthcare cost trend rate for other postretirement benefit obligations, service cost, and interest cost are less than $1 million, respectively. Assumed discount rates and expected returns on plan assets affect the amounts of net periodic benefit. A 25 basis point increase/decrease in the expected long-term return on plan assets would increase/decrease the net periodic benefit by $8 million for pension and other postretirement benefits plans. A 25 basis point increase/decrease in the discount rate would change the net periodic benefit by less than $1 million for pension and other postretirement benefits plans.

Defined Contribution Plans
SunTrust's employee benefit program includes a qualified defined contribution plan. For years ended December 31, 2015, 2014, and 2013, the 401(k) plan provided a dollar-for-dollar match on the first 6% of eligible pay that a participant, including executive participants, elected to defer. The related 401(k) Company expense was $102 million, $98 million, and $96 million for the years ended December 31, 2015, 2014, and 2013, respectively.
SunTrust also maintains the SunTrust Banks, Inc. Deferred Compensation Plan in which key executives of the Company are eligible. Matching contributions for the deferred compensation plan are the same percentage as provided in the 401(k) plan, subject to limitations imposed by the plans' provisions and applicable laws and regulations.
Matching contributions for both the Company's 401(k) plan and the deferred compensation plan fully vest upon two years of completed service. Furthermore, both plans permit an additional discretionary Company contribution equal to a fixed percentage of eligible pay. Discretionary contributions to the 401(k) plan and the deferred compensation plan are shown in the following table.

Guarantees
Guarantees
NOTE 16 – GUARANTEES
The Company has undertaken certain guarantee obligations in the ordinary course of business. The issuance of a guarantee imposes an obligation for the Company to stand ready to perform and make future payments should certain triggering events occur. Payments may be in the form of cash, financial instruments, other assets, shares of stock, or provision of the Company’s services. The following is a discussion of the guarantees that the Company has issued at December 31, 2015. The Company has also entered into certain contracts that are similar to guarantees, but that are accounted for as derivatives as discussed in Note 17, “Derivative Financial Instruments.”

Letters of Credit
Letters of credit are conditional commitments issued by the Company, generally to guarantee the performance of a client to a third party in borrowing arrangements, such as CP, bond financing, and similar transactions. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to clients and may be reduced by selling participations to third parties. The Company issues letters of credit that are classified as financial standby, performance standby, or commercial letters of credit.
At December 31, 2015 and 2014, the maximum potential amount of the Company’s obligation for issued financial and performance standby letters of credit was $2.9 billion and $3.0 billion, respectively. The Company’s outstanding letters of credit generally have a term of less than one year but may extend longer. Some standby letters of credit are designed to be drawn upon in the normal course of business and others are drawn upon only in circumstances of dispute or default in the underlying transaction to which the Company is not a party. In all cases, the Company is entitled to reimbursement from the client. If a letter of credit is drawn upon and reimbursement is not provided by the client, the Company may take possession of the collateral securing the letter of credit, where applicable.
The Company monitors its credit exposure under standby letters of credit in the same manner as it monitors other extensions of credit in accordance with its credit policies. An internal assessment of the PD and loss severity in the event of default is performed, consistent with the methodologies used for all commercial borrowers. The management of credit risk for letters of credit leverages the risk rating process to focus greater visibility on higher risk and/or higher dollar letters of credit. The allowance for credit losses associated with letters of credit is a component of the unfunded commitments reserve recorded in other liabilities in the Consolidated Balance Sheets and is included in the allowance for credit losses as disclosed in Note 7, “Allowance for Credit Losses.” Additionally, unearned fees relating to letters of credit are recorded in other liabilities. The net carrying amount of unearned fees was immaterial at December 31, 2015 and 2014.

Loan Sales and Servicing
STM, a consolidated subsidiary of the Company, originates and purchases residential mortgage loans, a portion of which are sold to outside investors in the normal course of business, through a combination of whole loan sales to GSEs, Ginnie Mae, and non-agency investors. Prior to 2008, the Company also sold mortgage loans through a limited number of Company-sponsored securitizations. When mortgage loans are sold, representations and warranties regarding certain attributes of the loans are made to third party purchasers. Subsequent to the sale, if a material underwriting deficiency or documentation defect is discovered, STM may be obligated to repurchase the mortgage loan or to reimburse an investor for losses incurred (make whole requests), if such deficiency or defect cannot be cured by STM within the specified period following discovery. Additionally, breaches of underwriting and servicing representations and warranties can result in loan repurchases, as well as adversely affect the valuation of MSRs, servicing advances, or other mortgage loan-related exposures, such as OREO. These representations and warranties may extend through the life of the mortgage loan. STM’s risk of loss under its representations and warranties is partially driven by borrower payment performance since investors will perform extensive reviews of delinquent loans as a means of mitigating losses.
Non-agency loan sales include whole loan sales and loans sold in private securitization transactions. While representations and warranties have been made related to these sales, they differ from those made in connection with loans sold to the GSEs in that non-agency loans may not be required to meet the same underwriting standards and non-agency investors may be required to demonstrate that an alleged breach is material and caused the investors' loss.
Loans sold to Ginnie Mae are insured by the FHA and guaranteed by the VA. As servicer, the Company may elect to repurchase delinquent loans in accordance with Ginnie Mae guidelines, however, the loans continue to be insured. The Company indemnifies the FHA and VA for losses related to loans not originated in accordance with their guidelines.
See Note 19, "Contingencies," for additional information on current legal matters related to loan sales.
The Company previously reached agreements in principle with Freddie Mac and Fannie Mae that relieve the Company of certain existing and future repurchase obligations related to loans sold from 2000-2008 to Freddie Mac and loans sold from 2000-2012 to Fannie Mae. Repurchase requests have declined significantly as a result of the settlements. Repurchase requests from GSEs, Ginnie Mae, and non-agency investors, for all vintages, are illustrated in the following table that summarizes demand activity for the years ended December 31.

The repurchase and make whole requests received have been primarily due to alleged material breaches of representations related to compliance with the applicable underwriting standards, including borrower misrepresentation and appraisal issues. STM performs a loan-by-loan review of all requests and contests demands to the extent they are not considered valid.

A significant degree of judgment is used to estimate the mortgage repurchase liability as the estimation process is inherently uncertain and subject to imprecision. The Company believes that its reserve appropriately estimates incurred losses based on its current analysis and assumptions, inclusive of the Freddie Mac and Fannie Mae settlement agreements, GSE owned loans serviced by third party servicers, loans sold to private investors, and other indemnifications.
Notwithstanding the aforementioned agreements with Freddie Mac and Fannie Mae settling certain aspects of the Company's repurchase obligations, those institutions preserve their right to require repurchases arising from certain types of events, and that preservation of rights can impact future losses of the Company. While the repurchase reserve includes the estimated cost of settling claims related to required repurchases, the Company's estimate of losses depends on its assumptions regarding GSE and other counterparty behavior, loan performance, home prices, and other factors. The related liability is recorded in other liabilities in the Consolidated Balance Sheets, and the related repurchase (benefit)/provision is recognized in mortgage production related income in the Consolidated Statements of Income.

In addition to representations and warranties related to loan sales, the Company makes representations and warranties that it will service the loans in accordance with investor servicing guidelines and standards, which may include (i) collection and remittance of principal and interest, (ii) administration of escrow for taxes and insurance, (iii) advancing principal, interest, taxes, insurance, and collection expenses on delinquent accounts, (iv) loss mitigation strategies including loan modifications, and (v) foreclosures.
The Company normally retains servicing rights when loans are transferred, however, servicing rights are occasionally sold to third parties. When MSRs are sold, the Company makes representations and warranties related to servicing standards and obligations, and recognizes a liability for contingent losses recorded in other liabilities in the Consolidated Balance Sheets. This liability, which is separate from the reserve for mortgage loan repurchases, totaled $14 million and $25 million at December 31, 2015 and 2014, respectively.

Contingent Consideration
The Company has contingent payment obligations related to certain business combination transactions. Payments are calculated using certain post-acquisition performance criteria. The potential obligation is recorded as an other liability, measured at the fair value of the contingent payments, which totaled $23 million and $27 million at December 31, 2015 and 2014, respectively.

Visa
The Company executes credit and debit transactions through Visa and MasterCard. The Company is a defendant, along with Visa and MasterCard (the “Card Associations”), as well as several other banks, in one of several antitrust lawsuits challenging the practices of the Card Associations (the “Litigation”). The Company entered into judgment and loss sharing agreements with Visa and certain other banks in order to apportion financial responsibilities arising from any potential adverse judgment or negotiated settlements related to the Litigation. Additionally, in connection with Visa's restructuring in 2007, shares of Visa common stock were issued to its financial institution members and the Company received its proportionate number of shares of Visa Inc. common stock, which were subsequently converted to Class B shares of Visa Inc. upon completion of Visa’s IPO in 2008. A provision of the original Visa By-Laws, which was restated in Visa's certificate of incorporation, contains a general indemnification provision between a Visa member and Visa that explicitly provides that each member's indemnification obligation is limited to losses arising from its own conduct and the specifically defined Litigation.
Agreements associated with Visa's IPO have provisions that Visa will fund a litigation escrow account, established for the purpose of funding judgments in, or settlements of, the Litigation. If the escrow account is insufficient to cover the Litigation losses, then Visa will issue additional Class A shares (“loss shares”). The proceeds from the sale of the loss shares would then be deposited in the escrow account. The issuance of the loss shares will cause a dilution of Visa's Class B shares as a result of an adjustment to lower the conversion factor of the Class B shares to Class A shares. Visa U.S.A.'s members are responsible for any portion of the settlement or loss on the Litigation after the escrow account is depleted and the value of the Class B shares is fully diluted.
In May 2009, the Company sold its 3.2 million Class B shares to the Visa Counterparty and entered into a derivative with the Visa Counterparty. Under the derivative, the Visa Counterparty is compensated by the Company for any decline in the conversion factor as a result of the outcome of the Litigation. Conversely, the Company is compensated by the Visa Counterparty for any increase in the conversion factor. The amount of payments made or received under the derivative is a function of the 3.2 million shares sold to the Visa Counterparty, the change in conversion rate, and Visa’s share price. The Visa Counterparty, as a result of its ownership of the Class B shares, is impacted by dilutive adjustments to the conversion factor of the Class B shares caused by the Litigation losses. The fair value of the derivative liability was immaterial at both December 31, 2015 and 2014; however, the ultimate impact to the Company could be significantly different based on the outcome of the Litigation.

Tax Credit Investments Sold
STCC, one of the Company's subsidiaries, previously obtained state and federal tax credits through the construction and development of affordable housing properties and continues to obtain state and federal tax credits through investments in affordable housing developments. STCC or its subsidiaries are limited and/or general partners in various partnerships established for the properties. Some of the investments that generate state tax credits may be sold to outside investors.
At December 31, 2015, there were four transactions outstanding that contain guarantee provisions stating that STCC will make payment to the outside investors if the tax credits become ineligible. STCC also guarantees that the general partner will perform on the delivery of the credits. The guarantees are expected to expire within a 15 year period from inception and have remaining years to expiry ranging from three to seven years. At December 31, 2015, the maximum potential amount that STCC could be obligated to pay under these guarantees is $19 million; however, STCC can seek recourse against the general partner. Additionally, STCC can seek reimbursement from the cash flow and residual values of the underlying affordable housing properties. At December 31, 2015 and 2014, an immaterial amount was accrued related to the obligation to deliver tax credits, and was recorded in other liabilities in the Consolidated Balance Sheets.
Public Deposits
The Company holds public deposits from various states in which it does business. Individual state laws require banks to collateralize public deposits, typically as a percentage of their public deposit balance in excess of FDIC insurance and may also require a cross-guarantee among all banks holding public deposits of the individual state. The amount of collateral required varies by state and may also vary by institution within each state, depending on the individual state's risk assessment of depository institutions. Certain of the states in which the Company holds public deposits use a pooled collateral method, whereby in the event of default of a bank holding public deposits, the collateral of the defaulting bank is liquidated to the extent necessary to recover the loss of public deposits of the defaulting bank. To the extent the collateral is insufficient, the remaining public deposit balances of the defaulting bank are recovered through an assessment of the other banks holding public deposits in that state. The maximum potential amount of future payments the Company could be required to make is dependent on a variety of factors, including the amount of public funds held by banks in the states in which the Company also holds public deposits and the amount of collateral coverage associated with any defaulting bank. Individual states appear to be monitoring this risk and evaluating collateral requirements; therefore, the likelihood that the Company would have to perform under this guarantee is dependent on whether any banks holding public funds default as well as the adequacy of collateral coverage.
Other
In the normal course of business, the Company enters into indemnification agreements and provides standard representations and warranties in connection with numerous transactions. These transactions include those arising from securitization activities, underwriting agreements, merger and acquisition agreements, swap clearing agreements, loan sales, contractual commitments, payment processing, sponsorship agreements, and various other business transactions or arrangements. The extent of the Company's obligations under these indemnification agreements depends upon the occurrence of future events; therefore, the Company's potential future liability under these arrangements is not determinable. STIS and STRH, broker-dealer affiliates of the Company, use a common third party clearing broker to clear and execute their customers' securities transactions and to hold customer accounts. Under their respective agreements, STIS and STRH agree to indemnify the clearing broker for losses that result from a customer's failure to fulfill its contractual obligations. As the clearing broker's rights to charge STIS and STRH have no maximum amount, the Company believes that the maximum potential obligation cannot be estimated. However, to mitigate exposure, the affiliate may seek recourse from the customer through cash or securities held in the defaulting customers' account. For the years ended December 31, 2015, 2014, and 2013, STIS and STRH experienced minimal net losses as a result of the indemnity. The clearing agreements expire in May 2020 for both STIS and STRH.
Derivative Financial Instruments
Derivative Financial Instruments
NOTE 17 - DERIVATIVE FINANCIAL INSTRUMENTS
The Company enters into various derivative financial instruments, both in a dealer capacity to facilitate client transactions and as an end user as a risk management tool. The ALCO monitors all derivative activities. When derivatives have been entered into with clients, the Company generally manages the risk associated with these derivatives within the framework of its VAR methodology that monitors total daily exposure and seeks to manage the exposure on an overall basis. Derivatives are also used as a risk management tool to hedge the Company’s balance sheet exposure to changes in identified cash flow and fair value risks, either economically or in accordance with hedge accounting provisions. The Company’s Corporate Treasury function is responsible for employing the various hedge accounting strategies to manage these objectives. Additionally, as a normal part of its operations, the Company enters into IRLCs on mortgage loans that are accounted for as freestanding derivatives and has certain contracts containing embedded derivatives that are measured, in their entirety, at fair value. All freestanding derivatives and any embedded derivatives that the Company bifurcates from the host contracts are measured at fair value in the Consolidated Balance Sheets in trading assets and derivative instruments and trading liabilities and derivative instruments. The associated gains and losses are either recognized in AOCI, net of tax, or within the Consolidated Statements of Income, depending upon the use and designation of the derivatives.
Credit and Market Risk Associated with Derivative Instruments
Derivatives expose the Company to counterparty credit risk if the counterparty to the derivative contract does not perform as expected. The Company minimizes the credit risk of derivatives by entering into transactions with counterparties with defined exposure limits based on their credit quality and in accordance with established policies and procedures. All counterparties are regularly reviewed by the Company’s Credit Risk Management division and appropriate action is taken to adjust the exposure to certain counterparties as necessary. The Company’s derivative transactions may also be governed by ISDA documentation or other legally enforceable industry standard master netting agreements. In certain cases and depending on the nature of the underlying derivative transactions, bilateral collateral agreements are also utilized. Furthermore, the Company and its subsidiaries are subject to OTC derivative clearing requirements, which require certain derivatives to be cleared through central clearinghouses with which the Company and other counterparties are required to post initial margin. To mitigate the risk of non-payment, variation margin is received or paid daily based on the net asset or liability position of the contracts.
When the Company has more than one outstanding derivative transaction with a single counterparty, and there exists a legal right of offset with that counterparty, the Company considers its exposure to the counterparty to be the net fair value of its derivative positions with that counterparty. If the net fair value is positive, then the counterparty asset value also reflects cash collateral held. At December 31, 2015, these net asset positions were $896 million, reflecting $1.4 billion of net derivative gains adjusted for cash and other collateral of $463 million that the Company held in relation to these positions. At December 31, 2014, reported net derivative assets were $1.1 billion, reflecting $1.5 billion of net derivative gains, adjusted for cash and other collateral of $386 million that the Company held in relation to these gain positions.
Derivatives also expose the Company to market risk. Market risk is the adverse effect that a change in market factors, such as interest rates, currency rates, equity prices, commodity prices, or implied volatility, has on the value of a derivative. Under an established risk governance framework, the Company comprehensively manages the market risk associated with its derivatives by establishing and monitoring limits on the types and degree of risk that may be undertaken. The Company continually measures this risk associated with its derivatives designated as trading instruments using a VAR methodology. Other tools and risk measures are also used to actively manage derivatives risk including scenario analysis and stress testing.
Derivative instruments are priced using observable market inputs at a mid-market valuation point and take into consideration appropriate valuation adjustments for collateral, market liquidity, and counterparty credit risk. For purposes of determining fair value adjustments to its OTC derivative positions, the Company takes into consideration the credit profile and likelihood of default by counterparties and itself, as well as its net exposure, which considers legally enforceable master netting agreements and collateral along with remaining maturities. Generally, the expected loss of each counterparty is estimated using the Company’s internal risk rating system. The risk rating system utilizes counterparty-specific PD and LGD estimates to derive the expected loss. The Company enhances its approach for determining fair value adjustments of derivatives by leveraging publicly available counterparty information. In particular, for purposes of determining the CVA, the Company incorporates market-based views of counterparty default probabilities derived from observed credit spreads in the CDS market when data of acceptable quality is available.
For purposes of estimating the Company’s own credit risk on derivative liability positions, the DVA, the Company uses probabilities of default from observable, market-based credit spreads. The Company adjusted the net fair value of its derivative contracts for estimates of net counterparty credit risk by approximately $4 million and $7 million at December 31, 2015 and 2014, respectively. The Company's approach toward determining fair value adjustments of derivative instruments is subject to ongoing internal review and enhancement. This review includes consideration of whether to include a funding valuation adjustment in the fair value measurement of derivatives, which relates to the funding cost or benefit associated with collateralized derivative positions. For additional information on the Company's fair value measurements, see Note 18, "Fair Value Election and Measurement."
Currently, the majority of the Company’s derivatives contain contingencies that relate to the creditworthiness of the Bank. These contingencies, which are contained in industry standard master netting agreements, may be considered events of default. Should the Bank be in default under any of these provisions, the Bank’s counterparties would be permitted to close out transactions with the Bank on a net basis, at amounts that would approximate the fair values of the derivatives, resulting in a single sum due by one party to the other. The counterparties would have the right to apply any collateral posted by the Bank against any net amount owed by the Bank. Additionally, certain of the Company’s derivative liability positions, totaling $1.1 billion in fair value at both December 31, 2015 and 2014, contain provisions conditioned on downgrades of the Bank’s credit rating. These provisions, if triggered, would either give rise to an ATE that permits the counterparties to close-out net and apply collateral or, where a CSA is present, require the Bank to post additional collateral. At December 31, 2015, the Bank carried senior long-term debt credit ratings of Baal/A-/A- from Moody’s, S&P, and Fitch, respectively. At December 31, 2015, ATEs have been triggered for less than $1 million in fair value liabilities. The maximum additional liability that could be triggered from ATEs was approximately $13 million at December 31, 2015. At December 31, 2015, $1.1 billion in fair value of derivative liabilities were subject to CSAs, against which the Bank has posted $1.0 billion in collateral, primarily in the form of cash. At December 31, 2015, if requested by the counterparty pursuant to the terms of the CSA, the Bank would be required to post additional collateral of approximately $7 million against these contracts if the Bank were downgraded to Baa3/BBB-. Further downgrades to Ba1/BB+ or below do not contain predetermined collateral posting levels.

Notional and Fair Value of Derivative Positions
The following tables present the Company’s derivative positions at December 31, 2015 and 2014. The notional amounts in the tables are presented on a gross basis and have been classified within derivative assets or derivative liabilities based on the estimated fair value of the individual contract at December 31, 2015 and 2014. Gross positive and gross negative fair value amounts associated with respective notional amounts are presented without consideration of any netting agreements, including collateral arrangements. Net fair value derivative amounts are adjusted on an aggregate basis, where applicable, to take into consideration the effects of legally enforceable master netting agreements, including any cash collateral received or paid, and are recognized in trading assets and derivative instruments or trading liabilities and derivative instruments on the Consolidated Balance Sheets. For contracts constituting a combination of options that contain a written option and a purchased option (such as a collar), the notional amount of each option is presented separately, with the purchased notional amount generally being presented as a derivative asset and the written notional amount being presented as a derivative liability. For contracts that contain a combination of options, the fair value is generally presented as a single value with the purchased notional amount if the combined fair value is positive, and with the written notional amount if the combined fair value is negative.

Netting of Derivative Instruments
The Company has various financial assets and financial liabilities that are subject to enforceable master netting agreements or similar agreements. The Company's securities borrowed or purchased under agreements to resell, and securities sold under agreements to repurchase, that are subject to enforceable master netting agreements or similar agreements, are discussed in Note 3, "Federal Funds Sold and Securities Financing Activities." The Company enters into ISDA or other legally enforceable industry standard master netting agreements with derivative counterparties. Under the terms of the master netting agreements, all transactions between the Company and the counterparty constitute a single business relationship such that in the event of default, the nondefaulting party is entitled to set off claims and apply property held by that party in respect of any transaction against obligations owed. Any payments, deliveries, or other transfers may be applied against each other and netted.
The following tables present total gross derivative instrument assets and liabilities at December 31, 2015 and 2014, which are adjusted to reflect the effects of legally enforceable master netting agreements and cash collateral received or paid on the net amount reported in the Consolidated Balance Sheets. Also included in the tables are financial instrument collateral related to legally enforceable master netting agreements that represents securities collateral received or pledged and customer cash collateral held at third party custodians. These amounts are not offset on the Consolidated Balance Sheets but are shown as a reduction to total derivative instrument assets and liabilities to derive net derivative assets and liabilities. These amounts are limited to the derivative asset/liability balance, and accordingly, do not include excess collateral received/pledged.

Credit Derivative Instruments
As part of SunTrust's trading businesses, the Company enters into contracts that are, in form or substance, written guarantees: specifically, CDS, risk participations, and TRS. The Company accounts for these contracts as derivatives and, accordingly, records these contracts at fair value, with changes in fair value recognized in trading income in the Consolidated Statements of Income.
The Company writes CDS, which are agreements under which the Company receives premium payments from its counterparty for protection against an event of default of a reference asset. In the event of default under the CDS, the Company would either settle its obligation net in cash or make a cash payment to its counterparty and take delivery of the defaulted reference asset, from which the Company may recover all, a portion, or none of the credit loss, depending on the performance of the reference asset. Events of default, as defined in the CDS agreements, are generally triggered upon the failure to pay and similar events related to the issuer(s) of the reference asset. When the Company has written CDS, all written CDS contracts reference single name corporate credits or corporate credit indices. The Company generally enters into offsetting CDS for the underlying reference asset, under which the Company pays a premium to its counterparty for protection against an event of default on the reference asset. The counterparties to these purchased CDS are generally of high creditworthiness and typically have ISDA master netting agreements in place that subject the CDS to master netting provisions, thereby mitigating the risk of non-payment to the Company. As such, at December 31, 2015, the Company did not have any material risk of making a non-recoverable payment on any written CDS. During 2015 and 2014, the only instances of default on written CDS were driven by credit indices with constituent credit default. In all cases where the Company made resulting cash payments to settle, the Company collected like amounts from the counterparties to the offsetting purchased CDS.
There were no written CDS at December 31, 2015. At December 31, 2014, written CDS had remaining terms of four years. The fair value of written CDS was $1 million at December 31, 2014. The maximum guarantees outstanding at December 31, 2014, as measured by the gross notional amount of written CDS, was $20 million. At December 31, 2015 and 2014, the gross notional amounts of purchased CDS contracts, which protect the Company against default of a reference asset, were $150 million and $190 million, respectively. The fair values of purchased CDS were $1 million and $5 million at December 31, 2015 and 2014, respectively.
The Company has also entered into TRS contracts on loans. The Company’s TRS business consists of matched trades, such that when the Company pays depreciation on one TRS, it receives the same amount on the matched TRS. To mitigate its credit risk, the Company typically receives initial cash collateral from the counterparty upon entering into the TRS and is entitled to additional collateral if the fair value of the underlying reference assets deteriorates. There were $2.2 billion and $2.3 billion of outstanding TRS notional balances at December 31, 2015 and 2014, respectively. The fair values of these TRS assets and liabilities at December 31, 2015 were $57 million and $52 million, respectively, and related collateral held at December 31, 2015 was $492 million. The fair values of the TRS assets and liabilities at December 31, 2014 were $19 million and $14 million, respectively, and related collateral held at December 31, 2014 was $373 million. For additional information on the Company's TRS contracts, see Note 10, "Certain Transfers of Financial Assets and Variable Interest Entities," as well as Note 18, "Fair Value Election and Measurement."
The Company writes risk participations, which are credit derivatives, whereby the Company has guaranteed payment to a dealer counterparty in the event the counterparty experiences a loss on a derivative, such as an interest rate swap, due to a failure to pay by the counterparty’s customer (the “obligor”) on that derivative. The Company monitors its payment risk on its risk participations by monitoring the creditworthiness of the obligors, which is based on the normal credit review process the Company would have performed had it entered into a derivative directly with the obligors. The obligors are all corporations or partnerships. The Company continues to monitor the creditworthiness of the obligors and the likelihood of payment could change at any time due to unforeseen circumstances. To date, no material losses have been incurred related to the Company’s written risk participations. At December 31, 2015 and 2014, the remaining terms on these risk participations generally ranged from less than one year to eight years and from one to nine years, respectively, with a weighted average on the maximum estimated exposure of 5.6 and 5.2 years, respectively. The Company’s maximum estimated exposure to written risk participations, as measured by projecting a maximum value of the guaranteed derivative instruments based on interest rate curve simulations and assuming 100% default by all obligors on the maximum values, was approximately $55 million and $31 million at December 31, 2015 and 2014, respectively. The fair values of the written risk participations were immaterial at both December 31, 2015 and 2014. As part of its trading activities, the Company may enter into purchased risk participations to mitigate credit exposure to a derivative counterparty.

Cash Flow Hedging Instruments
The Company utilizes a comprehensive risk management strategy to monitor sensitivity of earnings to movements in interest rates. Specific types of funding and principal amounts hedged are determined based on prevailing market conditions and the shape of the yield curve. In conjunction with this strategy, the Company may employ various interest rate derivatives as risk management tools to hedge interest rate risk from recognized assets and liabilities or from forecasted transactions. The terms and notional amounts of derivatives are determined based on management’s assessment of future interest rates, as well as other factors.
Interest rate swaps have been designated as hedging the exposure to the benchmark interest rate risk associated with floating rate loans. At December 31, 2015 and 2014, the maturities for hedges of floating rate loans ranged from less than one year to seven years and from less than one year to four years, respectively, with the weighted average being 3.3 and 1.9 years, respectively. These hedges have been highly effective in offsetting the designated risks, yielding an immaterial amount of ineffectiveness for the year ended December 31, 2015 and 2014. At December 31, 2015, $229 million of deferred net pre-tax gains on derivative instruments designated as cash flow hedges on floating rate loans recognized in AOCI are expected to be reclassified into net interest income during the next twelve months. The amount to be reclassified into income incorporates the impact from both active and terminated or de-designated cash flow hedges, including the net interest income earned on the active hedges, assuming no changes in LIBOR. The Company may choose to terminate or de-designate a hedging relationship due to a change in the risk management objective for that specific hedge item, which may arise in conjunction with an overall balance sheet management strategy.
Fair Value Hedging Instruments
The Company enters into interest rate swap agreements as part of the Company’s risk management objectives for hedging its exposure to changes in fair value due to changes in interest rates. These hedging arrangements convert fixed rate, long-term debt to floating rates. Consistent with this objective, the Company reflects the accrued contractual interest on the hedged item and the related swaps as part of current period interest expense. There were no components of derivative gains or losses excluded in the Company’s assessment of hedge effectiveness related to the fair value hedges.
Economic Hedging Instruments and Trading Activities
In addition to designated hedge accounting relationships, the Company also enters into derivatives as an end user to economically hedge risks associated with certain non-derivative and derivative instruments, along with entering into derivatives in a trading capacity with its clients.
The primary risks that the Company economically hedges are interest rate risk, foreign exchange risk, and credit risk. The Company mitigates these risks by entering into offsetting derivatives either on an individual basis or collectively on a macro basis.
The Company utilizes interest rate derivatives related to:
•
MSRs. The Company hedges these instruments with a combination of interest rate derivatives, including forward and option contracts, futures, and forward rate agreements.
•
IRLCs and mortgage LHFS. The Company hedges these instruments using forward and option contracts, futures, and forward rate agreements.
The Company is exposed to volatility and changes in foreign exchange rates associated with certain commercial loans. To hedge against this foreign exchange rate risk, the Company enters into foreign exchange rate contracts that provide for the future receipt and delivery of foreign currency at previously agreed-upon terms.
The Company enters into CDS to hedge credit risk associated with certain loans held within its Wholesale Banking segment. The Company accounts for these contracts as derivatives and, accordingly, recognizes these contracts at fair value, with changes in fair value recognized in other noninterest income in the Consolidated Statements of Income.
Trading activity primarily includes interest rate swaps, equity derivatives, CDS, futures, options, foreign currency contracts, and commodities. These derivatives are entered into in a dealer capacity to facilitate client transactions, or are utilized as a risk management tool by the Company as an end user (predominantly in certain macro-hedging strategies). The macro-hedging strategies are focused on managing the Company’s overall interest rate risk exposure that is not otherwise hedged by derivatives or in connection with specific hedges and, therefore, the Company does not specifically associate individual derivatives with specific assets or liabilities.
Fair Value Election and Measurement
Fair Value Election and Measurement
NOTE 18 - FAIR VALUE ELECTION AND MEASUREMENT
The Company measures certain assets and liabilities at fair value, which are classified as level 1, 2, or 3 within the fair value hierarchy, as shown below, on the basis of whether the measurement employs observable or unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s own assumptions taking into account information about market participant assumptions that is readily available.
•
Level 1: Quoted prices for identical instruments in active markets
•
Level 2: Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets
•
Level 3: Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable
Fair value is defined as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. The Company’s recurring fair value measurements are based on either a requirement to measure such assets and liabilities at fair value or on the Company’s election to measure certain financial assets and liabilities at fair value. Assets and liabilities that are required to be measured at fair value on a recurring basis include trading securities, securities AFS, and derivative financial instruments. Assets and liabilities that the Company has elected to measure at fair value on a recurring basis include MSRs and certain LHFS, LHFI, trading loans, and issuances of fixed rate debt.
The Company elects to measure certain assets and liabilities at fair value to better align its financial performance with the economic value of actively traded or hedged assets or liabilities. The use of fair value also enables the Company to mitigate non-economic earnings volatility caused from financial assets and liabilities being carried at different bases of accounting, as well as to more accurately portray the active and dynamic management of the Company’s balance sheet.
The Company uses various valuation techniques and assumptions in estimating fair value. The assumptions used to estimate the value of an instrument have varying degrees of impact to the overall fair value of an asset or liability. This process involves the gathering of multiple sources of information, including broker quotes, values provided by pricing services, trading activity in other identical or similar securities, market indices, and pricing matrices. When observable market prices for the asset or liability are not available, the Company employs various modeling techniques, such as discounted cash flow analyses, to estimate fair value. Models used to produce material financial reporting information are validated prior to use and following any material change in methodology. Their performance is monitored quarterly, and any material deterioration in model performance is addressed. This review is performed by an internal group that reports to the Corporate Risk Function.
The Company has formal processes and controls in place to support the appropriateness of its fair value estimates. For fair values obtained from a third party, or those that include certain trader estimates of fair value, there is an independent price validation function that provides oversight for these estimates. For level 2 instruments and certain level 3 instruments, the validation generally involves evaluating pricing received from two or more third party pricing sources that are widely used by market participants. The Company evaluates this pricing information from both a qualitative and quantitative perspective and determines whether any pricing differences exceed acceptable thresholds. If thresholds are exceeded, the Company assesses differences in valuation approaches used, which may include contacting a pricing service to gain further insight into the valuation of a particular security or class of securities to resolve the pricing variance, which could include an adjustment to the price used for financial reporting purposes.
The Company classifies instruments within level 2 in the fair value hierarchy when it determines that external pricing sources estimated fair value using prices for similar instruments trading in active markets. A wide range of quoted values from pricing sources may imply a reduced level of market activity and indicate that significant adjustments to price indications have been made. In such cases, the Company evaluates whether the asset or liability should be classified as level 3.
Determining whether to classify an instrument as level 3 involves judgment and is based on a variety of subjective factors, including whether a market is inactive. A market is considered inactive if significant decreases in the volume and level of activity for the asset or liability have been observed. In making this determination the Company evaluates the number of recent transactions in either the primary or secondary market, whether or not price quotations are current, the nature of market participants, the variability of price quotations, the breadth of bid/ask spreads, declines in, or the absence of, new issuances, and the availability of public information. When a market is determined to be inactive, significant adjustments may be made to price indications when estimating fair value. In making these adjustments the Company seeks to employ assumptions a market participant would use to value the asset or liability, including consideration of illiquidity in the referenced market.

The following tables present the change in fair value during the years ended December 31, 2015, 2014, and 2013 of financial instruments for which the FVO has been elected, as well as for MSRs. The tables do not reflect the change in fair value attributable to related economic hedges the Company uses to mitigate the market-related risks associated with the financial instruments. Generally, changes in the fair value of economic hedges are recognized in trading income, mortgage production related income, mortgage servicing related income, or other noninterest income as appropriate, and are designed to partially offset the change in fair value of the financial instruments referenced in the tables below. The Company’s economic hedging activities are deployed at both the instrument and portfolio level.

The following is a discussion of the valuation techniques and inputs used in estimating fair value measurements for assets and liabilities measured at fair value on a recurring basis and classified as level 2 or 3.
Trading Assets and Derivative Instruments and Securities Available for Sale
Unless otherwise indicated, trading assets are priced by the trading desk and securities AFS are valued by an independent third party pricing service.

Federal agency securities
The Company includes in this classification securities issued by federal agencies and GSEs. Agency securities consist of debt obligations issued by HUD, FHLB, and other agencies or collateralized by loans that are guaranteed by the SBA and are, therefore, backed by the full faith and credit of the U.S. government. For SBA instruments, the Company estimated fair value based on pricing from observable trading activity for similar securities or obtained fair values from a third party pricing service. Accordingly, the Company classified these instruments as level 2.
U.S. states and political subdivisions
The Company’s investments in U.S. states and political subdivisions (collectively “municipals”) include obligations of county and municipal authorities and agency bonds, which are general obligations of the municipality or are supported by a specified revenue source. Holdings were geographically dispersed, with no significant concentrations in any one state or municipality. Additionally, all AFS municipal obligations classified as level 2 are highly rated or are otherwise collateralized by securities backed by the full faith and credit of the federal government.
Level 3 AFS municipal securities at December 31, 2015 and 2014 includes an immaterial amount of bonds that are redeemable with the issuer at par and cannot be traded in the market. As such, no significant observable market data for these instruments is available; therefore, these securities are priced at par.

MBS – agency
Agency MBS includes pass-through securities and collateralized mortgage obligations issued by GSEs and U.S. government agencies, such as Fannie Mae, Freddie Mac, and Ginnie Mae. Each security contains a guarantee by the issuing GSE or agency. For agency MBS, the Company estimated fair value based on pricing from observable trading activity for similar securities or obtained fair values from a third party pricing service; accordingly, the Company has classified these instruments as level 2.
MBS – private
Private MBS includes purchased interests in third party securitizations, as well as retained interests in Company-sponsored securitizations of 2006 and 2007 vintage residential mortgages (including both prime jumbo fixed rate collateral and floating rate collateral). At the time of purchase or origination, these securities had high investment grade ratings; however, through the credit crisis, they experienced deterioration in credit quality leading to downgrades to non-investment grade levels. The Company obtains pricing for these securities from an independent pricing service. The Company evaluates third party pricing to determine the reasonableness of the information relative to changes in market data, such as any recent trades, information received from market participants and analysts, and/or changes in the underlying collateral performance. The Company continued to classify private MBS as level 3, as the Company believes that available third party pricing relies on significant unobservable assumptions, as evidenced by a persistently wide bid-ask price range and variability in pricing from the pricing services, particularly for the vintage and exposures held by the Company.
CLO Securities
CLO preference share exposure is estimated at fair value based on pricing from observable trading activity for similar securities. Accordingly, the Company has classified these instruments as level 2.
Asset-Backed Securities
ABS classified as securities AFS includes purchased interests in third party securitizations collateralized by home equity loans and are valued based on third party pricing with significant unobservable assumptions; as such, they are classified as level 3.
Corporate and other debt securities
Corporate debt securities are predominantly comprised of senior and subordinate debt obligations of domestic corporations and are classified as level 2. Other debt securities in level 3 primarily include bonds that are not actively traded in the market. As such, valuation judgments are highly subjective. The Company estimates the fair value of these bonds using market comparable bond index yields as limited observable market data exists.
Commercial Paper
From time to time, the Company acquires third party CP that is generally short-term in nature (less than 30 days) and highly rated. The Company estimates the fair value of this CP based on observable pricing from executed trades of similar instruments; as such, CP is classified as level 2.
Equity securities
Equity securities classified as securities AFS primarily include FHLB of Atlanta stock and Federal Reserve Bank of Atlanta stock, which are redeemable with the issuer at cost and cannot be traded in the market. As such, observable market data for these instruments is not available and they are classified as level 3. The Company accounts for the stock based on industry guidance that requires these investments be carried at cost and evaluated for impairment based on the ultimate recovery of cost.

Derivative instruments
The Company holds derivative instruments for both trading and risk management purposes. Level 1 derivative instruments generally include exchange-traded futures or option contracts for which pricing is readily available. The Company’s level 2 instruments are predominantly OTC swaps, options, and forwards, measured using observable market assumptions for interest rates, foreign exchange, equity, and credit. Because fair values for OTC contracts are not readily available, the Company estimates fair values using internal, but standard, valuation models. The selection of valuation models is driven by the type of contract: for option-based products, the Company uses an appropriate option pricing model such as Black-Scholes. For forward-based products, the Company’s valuation methodology is generally a discounted cash flow approach.
The Company's derivative instruments classified as level 2 are primarily transacted in the institutional dealer market and priced with observable market assumptions at a mid-market valuation point, with appropriate valuation adjustments for liquidity and credit risk. To this end, the Company has evaluated liquidity premiums required by market participants, as well as the credit risk of its counterparties and its own credit. The Company has considered factors such as the likelihood of default by itself and its counterparties, its net exposures, and remaining maturities in determining the appropriate fair value adjustments to record. See Note 17, “Derivative Financial Instruments,” for additional information on the Company's derivative instruments.
The Company's derivative instruments classified as level 3 include IRLCs that satisfy the criteria to be treated as derivative financial instruments. The fair value of IRLCs on residential LHFS, while based on interest rates observable in the market, is highly dependent on the ultimate closing of the loans. These “pull-through” rates are based on the Company’s historical data and reflect the Company’s best estimate of the likelihood that a commitment will result in a closed loan. As pull-through rates increase, the fair value of IRLCs also increases. Servicing value is included in the fair value of IRLCs, and the fair value of servicing is determined by projecting cash flows, which are then discounted to estimate an expected fair value. The fair value of servicing is impacted by a variety of factors, including prepayment assumptions, discount rates, delinquency rates, contractually specified servicing fees, servicing costs, and underlying portfolio characteristics. Because these inputs are not transparent in market trades, IRLCs are considered to be level 3 assets. During the years ended December 31, 2015 and 2014, the Company transferred $161 million and $245 million, respectively, of net IRLCs out of level 3 as the associated loans were closed.
    
Trading loans
The Company engages in certain businesses whereby the election to measure loans at fair value for financial reporting aligns with the underlying business purpose. Specifically, the loans that are included within this classification are: (i) loans made, or acquired, in connection with the Company’s TRS business, (ii) loans backed by the SBA, and (iii) the loan sales and trading business within the Company’s Wholesale Banking segment. See Note 10, "Certain Transfers of Financial Assets and Variable Interest Entities," and Note 17, “Derivative Financial Instruments,” for further discussion of this business. All of these loans are classified as level 2, due to the market data that the Company uses in the estimate of fair value.
The loans made in connection with the Company’s TRS business are short-term, senior demand loans that are collateralized by cash. While these loans do not trade in the market, the Company believes that the par amount of the loans approximates fair value and no unobservable assumptions are used by the Company to value these loans. At December 31, 2015 and 2014, the Company had outstanding $2.2 billion and $2.3 billion, respectively, of these short-term loans measured at fair value.
SBA loans are similar to SBA securities discussed herein under “Federal agency securities,” except for their legal form. In both cases, the Company trades instruments that are fully guaranteed by the U.S. government as to contractual principal and interest and there is sufficient observable trading activity upon which to base the estimate of fair value. As these SBA loans are fully guaranteed, the changes in fair value are attributable to factors other than instrument-specific credit risk.
The loans from the Company’s sales and trading business are commercial and corporate leveraged loans that are either traded in the market or for which similar loans trade. The Company elected to measure these loans at fair value since they are actively traded. For the years ended December 31, 2015, 2014, and 2013, the Company recognized an immaterial amount of gains/(losses) in the Consolidated Statements of Income due to changes in fair value attributable to instrument-specific credit risk. The Company is able to obtain fair value estimates for substantially all of these loans through a third party valuation service that is broadly used by market participants. While most of the loans are traded in the market, the Company does not believe that trading activity qualifies the loans as level 1 instruments, as the volume and level of trading activity is subject to variability and the loans are not exchange-traded. At December 31, 2015 and 2014, $356 million and $284 million, respectively, of loans related to the Company’s trading business were held in inventory.

Loans Held for Sale and Loans Held for Investment
Residential LHFS
The Company values certain newly-originated mortgage LHFS predominantly at fair value based upon defined product criteria. The Company chooses to fair value these mortgage LHFS to eliminate the complexities and inherent difficulties of achieving hedge accounting and to better align reported results with the underlying economic changes in value of the loans and related hedge instruments. Origination fees are recognized within mortgage production related income in the Consolidated Statements of Income when earned at the time of closing. The servicing value is included in the fair value of the loan and initially recognized at the time the Company enters into IRLCs with borrowers. The Company uses derivative instruments to economically hedge changes in interest rates and the related impact on servicing value in the fair value of the loan. The mark-to-market adjustments related to LHFS and the associated economic hedges are captured in mortgage production related income.
LHFS classified as level 2 are primarily agency loans which trade in active secondary markets and are priced using current market pricing for similar securities, adjusted for servicing, interest rate risk, and credit risk. Non-agency residential mortgages are also included in level 2 LHFS. Transfers of certain mortgage LHFS into level 3 during the years ended December 31, 2015 and 2014 were largely due to borrower defaults or the identification of other loan defects impacting the marketability of the loans.
For residential loans that the Company has elected to measure at fair value, the Company considers the component of the fair value changes due to instrument-specific credit risk, which is intended to be an approximation of the fair value change attributable to changes in borrower-specific credit risk. For the years ended December 31, 2015, 2014, and 2013, the Company recognized an immaterial amount of gains/(losses) in the Consolidated Statements of Income due to changes in fair value attributable to borrower-specific credit risk. In addition to borrower-specific credit risk, there are other, more significant, variables that drive changes in the fair values of the loans, including interest rates and general conditions in the markets for the loans.
LHFI
LHFI classified as level 3 includes predominantly mortgage loans that are not marketable, largely due to the identification of loan defects. The Company chooses to measure these mortgage LHFI at fair value to better align reported results with the underlying economic changes in value of the loans and any related hedging instruments. The Company values these loans using a discounted cash flow approach based on assumptions that are generally not observable in current markets, such as prepayment speeds, default rates, loss severity rates, and discount rates. These assumptions have an inverse relationship to the overall fair value. Level 3 LHFI also includes mortgage loans that are valued using collateral based pricing. Changes in the applicable housing price index since the time of the loan origination are considered and applied to the loan's collateral value. An additional discount representing the return that a buyer would require is also considered in the overall fair value.
Mortgage Servicing Rights
The Company records MSR assets at fair value using a discounted cash flow approach. The fair values of MSRs are impacted by a variety of factors, including prepayment assumptions, spreads, delinquency rates, contractually specified servicing fees, servicing costs, and underlying portfolio characteristics. The underlying assumptions and estimated values are corroborated by values received from independent third parties based on their review of the servicing portfolio, and comparisons to market transactions. Because these inputs are not transparent in market trades, MSRs are classified as level 3 assets. For additional information see Note 9, "Goodwill and Other Intangible Assets."

Liabilities
Trading liabilities and derivative instruments
Trading liabilities are primarily comprised of derivative contracts, but also include various contracts (primarily U.S. Treasury securities, corporate and other debt securities) that the Company uses in certain of its trading businesses. The Company's valuation methodologies for these derivative contracts and securities are consistent with those discussed within the corresponding sections herein under “Trading Assets and Derivative Instruments and Securities Available for Sale.”
During the second quarter of 2009, in connection with its sale of Visa Class B shares, the Company entered into a derivative contract whereby the ultimate cash payments received or paid, if any, under the contract are based on the ultimate resolution of litigation involving Visa. The value of the derivative was estimated based on the Company’s expectations regarding the ultimate resolution of that litigation, which involved a high degree of judgment and subjectivity. Accordingly, the value of the related derivative liability is classified as a level 3 instrument. See Note 16, "Guarantees," for a discussion of the valuation assumptions.
Long-term debt
The Company has elected to measure at fair value certain fixed rate debt issuances of public debt which are valued by obtaining price indications from a third party pricing service and utilizing broker quotes to corroborate the reasonableness of those marks. Additionally, information from market data of recent observable trades and indications from buy side investors, if available, are taken into consideration as additional support for the value. Due to the availability of this information, the Company determined that the appropriate classification for these debt issuances is level 2. The election to fair value certain fixed rate debt issuances was made to align the accounting for the debt with the accounting for offsetting derivative positions, without having to apply hedge accounting, thus avoiding the complex and time consuming fair value hedge accounting requirements.
The Company’s public debt measured at fair value impacts earnings predominantly through changes in the Company’s credit spreads as the Company has entered into derivative financial instruments that economically convert the interest rate on the debt from a fixed to a floating rate. The estimated earnings impact from changes in credit spreads above U.S. Treasury rates resulted in an immaterial amount of losses for the year ended December 31, 2015, and losses of $19 million and gains of $40 million for the years ended December 31, 2014 and 2013, respectively.

Other liabilities
The Company’s other liabilities that are measured at fair value on a recurring basis include contingent consideration obligations related to acquisitions. Contingent consideration associated with acquisitions is adjusted to fair value until settled. As the assumptions used to measure fair value are based on internal metrics that are not market observable, the earn-out liability is considered level 3.

The valuation technique and range, including weighted average, of the unobservable inputs associated with the Company's level 3 assets and liabilities are as follows:

The following tables present a reconciliation of the beginning and ending balances for assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (other than servicing rights which are disclosed in Note 9, “Goodwill and Other Intangible Assets”). Transfers into and out of the fair value hierarchy levels are assumed to occur at the end of the period in which the transfer occurred. None of the transfers into or out of level 3 have been the result of using alternative valuation approaches to estimate fair values. There were no transfers between level 1 and 2 during the years ended December 31, 2015 and 2014.

6 Amounts are generally included in mortgage production related income; however, the mark on certain fair value loans is included in trading income.
7 Amounts included in earnings are recognized in other noninterest expense.


Non-recurring Fair Value Measurements
The following tables present losses recognized on assets still held at period end, and measured at fair value on a non-recurring basis, for the years ended December 31, 2015 and 2014. Adjustments to fair value generally result from the application of LOCOM or through write-downs of individual assets. The tables do not reflect changes in fair value attributable to economic hedges the Company may have used to mitigate interest rate risk associated with LHFS and MSRs.

Discussed below are the valuation techniques and inputs used in developing fair value measurements for assets measured at fair value on a non-recurring basis and classified as level 1, 2, and/or 3.
Loans Held for Sale
At December 31, 2015, LHFS consisted of commercial loans that were valued using significant unobservable assumptions from comparably rated loans. As such, limited observable market data exists as these loans are not actively traded, and, accordingly, are classified as level 3.
At December 31, 2014, LHFS classified as level 1 consisted of commercial and industrial loans for which pricing is readily available, and level 2 assets consisted primarily of agency and non-agency residential mortgages, which were measured using observable collateral valuations, and corporate loans, all of which are accounted for at LOCOM. Level 3 assets at December 31, 2014 consisted primarily of indirect auto loans and tax-exempt municipal leases that incurred fair value adjustments upon being transferred to LHFS, as the Company elected to actively market these loans for sale. These loans were valued consistent with the methodology discussed in the Recurring Fair Value Measurements section of this footnote.
During 2014, the Company transferred $470 million of C&I loans to LHFS, as the Company elected to actively market these loans for sale; $340 million of these loans were tax-exempt municipal leases included in level 3 and the remainder were included in level 1. Also during 2014, the Company transferred $38 million of residential mortgage NPLs to LHFS, which are included in level 2, as the Company elected to actively market these loans for sale. These loans were predominantly reported at amortized cost prior to transferring to LHFS, however, a portion of the NPLs were carried at fair value. Additionally, during 2014, the Company transferred approximately $600 million of indirect auto loans to LHFS, included in level 3, which the Company elected to actively market for sale.
Loans Held for Investment
At December 31, 2015 and 2014, LHFI consisted primarily of consumer and residential real estate loans discharged in Chapter 7 bankruptcy that had not been reaffirmed by the borrower, as well as nonperforming CRE loans for which specific reserves had been recognized. As these loans have been classified as nonperforming, cash proceeds from the sale of the underlying collateral is the expected source of repayment for a majority of these loans. Accordingly, the fair value of these loans is derived from the estimated fair value of the underlying collateral, incorporating market data if available. There were no gains or losses during the years ended December 31, 2015 and 2014, as the charge-offs related to these loans are a component of the ALLL. Due to the lack of market data for similar assets, all of these loans are considered level 3.

OREO
OREO is measured at the lower of cost, or fair value less costs to sell. OREO classified as level 2 consists primarily of residential homes, commercial properties, and vacant lots and land for which binding purchase agreements exist. OREO classified as level 3 consists primarily of residential homes, commercial properties, and vacant lots and land for which initial valuations are based on property-specific appraisals, broker pricing opinions, or other limited, highly subjective market information. Updated value estimates are received regularly on level 3 OREO.

Affordable Housing
The Company evaluates its consolidated affordable housing properties for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Impairment is recognized if the carrying amount of the property exceeds its fair value. During the year ended December 31, 2015, the Company did not recognize impairment or increased estimated net realizable values on any of its affordable housing properties.
During the first quarter of 2014, the Company decided to actively market for sale certain consolidated affordable housing properties, and accordingly, recognized an initial impairment charge of $36 million to adjust the carrying values of these properties to their estimated net realizable values, which were obtained from a third party broker opinion and were considered level 3. Subsequently during 2014, the Company recognized recoveries of $15 million on these affordable housing properties as a result of increased estimated net realizable values. Additionally, the Company recognized gains of $19 million during the year ended December 31, 2015 on the sale of these affordable housing investments.

Other Assets
Other assets consists of other repossessed assets, assets under operating leases where the Company is the lessor, land held for sale, and equity method investments.
Other repossessed assets comprises repossessed personal property that is measured at fair value less cost to sell. These assets are considered level 3 as their fair value is determined based on a variety of subjective, unobservable factors. There were no losses recognized by the Company on other repossessed assets during the years ended December 31, 2015 and 2014, as the impairment charges on repossessed personal property were a component of the ALLL.
The Company monitors the fair value of assets under operating leases where the Company is the lessor and recognizes impairment on the leased asset to the extent the carrying value is not recoverable and the fair value is less than its carrying value. Fair value is determined using collateral specific pricing digests, external appraisals, broker opinions, recent sales data from industry equipment dealers, and the discounted cash flows derived from the underlying lease agreement. As market data for similar assets and lease arrangements is available and used in the valuation, these assets are considered level 2. During the years ended December 31, 2015 and 2014, the Company recognized impairment charges of $6 million and $59 million, respectively, attributable to the fair value of various personal property under operating leases.
Land held for sale is recorded at the lesser of carrying value or fair value less cost to sell. Land held for sale is considered level 2 as its fair value is determined based on market comparables and broker opinions. Impairment charges the Company recognized on land held for sale was immaterial and $5 million during the years ended December 31, 2015 and 2014, respectively.

(b) 

The following methods and assumptions were used by the Company in estimating the fair value of financial instruments:
(a)
Cash and cash equivalents are valued at their carrying amounts, which are reasonable estimates of fair value due to the relatively short period to maturity of the instruments.
(b)
Trading assets and derivative instruments, securities AFS, and trading liabilities and derivative instruments that are classified as level 1 are valued based on quoted market prices. For those instruments classified as level 2 or 3, refer to the respective valuation discussions within this footnote.
(c)
LHFS are generally valued based on observable current market prices or, if quoted market prices are not available, quoted market prices of similar instruments. Refer to the LHFS section within this footnote for further discussion. When valuation assumptions are not readily observable in the market, instruments are valued based on the best available data to approximate fair value. This data may be internally developed and considers risk premiums that a market participant would require under then-current market conditions.
(d)
LHFI fair values are based on a hypothetical exit price, which does not represent the estimated intrinsic value of the loan if held for investment. The assumptions used are expected to approximate those that a market participant purchasing the loans would use to value the loans, including a market risk premium and liquidity discount. Estimating the fair value of the loan portfolio when loan sales and trading markets are illiquid or nonexistent requires significant judgment.
Generally, the Company measures fair value for LHFI based on estimated future discounted cash flows using current origination rates for loans with similar terms and credit quality, which derived an estimated value of 101% and 100% on the loan portfolio’s net carrying value at December 31, 2015 and 2014, respectively. The value derived from origination rates likely does not represent an exit price; therefore, an incremental market risk and liquidity discount was applied when estimating the fair value of these loans. The discounted value is a function of a market participant’s required yield in the current environment and is not a reflection of the expected cumulative losses on the loans.
(e)
Deposit liabilities with no defined maturity such as DDAs, NOW/money market accounts, and savings accounts have a fair value equal to the amount payable on demand at the reporting date (i.e., their carrying amounts). Fair values for CDs are estimated using a discounted cash flow approach that applies current interest rates to a schedule of aggregated expected maturities. The assumptions used in the discounted cash flow analysis are expected to approximate those that market participants would use in valuing deposits. The value of long-term relationships with depositors is not taken into account in estimating fair values.
(f)
Fair values for short-term borrowings and certain long-term debt are based on quoted market prices for similar instruments or estimated discounted cash flows utilizing the Company’s current incremental borrowing rate for similar types of instruments. For long-term debt that the Company measures at fair value, refer to the respective valuation section within this footnote. For level 3 debt, the terms are unique in nature or there are no similar instruments that can be used to value the instrument without using significant unobservable assumptions. In these situations, the Company reviews current borrowing rates along with the collateral levels that secure the debt in determining an appropriate fair value adjustment.
Unfunded loan commitments and letters of credit are not included in the table above. At December 31, 2015 and 2014, the Company had $66.2 billion and $56.5 billion, respectively, of unfunded commercial loan commitments and letters of credit. A reasonable estimate of the fair value of these instruments is the carrying value of deferred fees plus the related unfunded commitments reserve, which was a combined $66 million and $59 million at December 31, 2015 and 2014, respectively. No active trading market exists for these instruments, and the estimated fair value does not include value associated with the borrower relationship. The Company does not estimate the fair values of consumer unfunded lending commitments which can generally be canceled by providing notice to the borrower.

NOTE 19 – CONTINGENCIES
Litigation and Regulatory Matters
In the ordinary course of business, the Company and its subsidiaries are parties to numerous civil claims and lawsuits and subject to regulatory examinations, investigations, and requests for information. Some of these matters involve claims for substantial amounts. The Company’s experience has shown that the damages alleged by plaintiffs or claimants are often overstated, based on unsubstantiated legal theories, unsupported by facts, and/or bear no relation to the ultimate award that a court might grant. Additionally, the outcome of litigation and regulatory matters and the timing of ultimate resolution are inherently difficult to predict. These factors make it difficult for the Company to provide a meaningful estimate of the range of reasonably possible outcomes of claims in the aggregate or by individual claim. However, on a case-by-case basis, reserves are established for those legal claims in which it is probable that a loss will be incurred and the amount of such loss can be reasonably estimated. The Company's financial statements at December 31, 2015 reflect the Company's current best estimate of probable losses associated with these matters, including costs to comply with various settlement agreements, where applicable. The actual costs of resolving these claims may be substantially higher or lower than the amounts reserved.
For a limited number of legal matters in which the Company is involved, the Company is able to estimate a range of reasonably possible losses in excess of related reserves, if any. Management currently estimates these losses to range from $0 to approximately $170 million. This estimated range of reasonably possible losses represents the estimated possible losses over the life of such legal matters, which may span a currently indeterminable number of years, and is based on information available at December 31, 2015. The matters underlying the estimated range will change from time to time, and actual results may vary significantly from this estimate. Those matters for which an estimate is not possible are not included within this estimated range; therefore, this estimated range does not represent the Company’s maximum loss exposure. Based on current knowledge, it is the opinion of management that liabilities arising from legal claims in excess of the amounts currently reserved, if any, will not have a material impact on the Company’s financial condition, results of operations, or cash flows. However, in light of the significant uncertainties involved in these matters and the large or indeterminate damages sought in some of these matters, an adverse outcome in one or more of these matters could be material to the Company’s financial condition, results of operations, or cash flows for any given reporting period.
The following is a description of certain litigation and regulatory matters:
Card Association Antitrust Litigation
The Company is a defendant, along with Visa and MasterCard, as well as several other banks, in several antitrust lawsuits challenging their practices. For a discussion regarding the Company’s involvement in this litigation matter, see Note 16, “Guarantees.”

Lehman Brothers Holdings, Inc. Litigation
Beginning in October 2008, STRH, along with other underwriters and individuals, were named as defendants in several individual and putative class action complaints filed in the U.S. District Court for the Southern District of New York and state and federal courts in Arkansas, California, Texas, and Washington. Plaintiffs alleged violations of Sections 11 and 12 of the Securities Act of 1933 and/or state law for allegedly false and misleading disclosures in connection with various debt and preferred stock offerings of Lehman Brothers Holdings, Inc. ("Lehman Brothers") and sought unspecified damages. All cases were transferred for coordination to the multi-district litigation captioned In re Lehman Brothers Equity/Debt Securities Litigation pending in the U.S. District Court for the Southern District of New York. Defendants filed a motion to dismiss all claims asserted in the class action. On July 27, 2011, the District Court granted in part and denied in part the motion to dismiss the claims against STRH and the other underwriter defendants in the class action. A settlement with the class plaintiffs was approved by the Court and the class settlement approval process was completed. A number of individual lawsuits and smaller putative class actions remained following the class settlement. STRH settled two such individual actions. The other individual lawsuits were dismissed. In two of such dismissed individual actions, the plaintiffs were unable to appeal the dismissals of their claims until their claims against a third party were resolved. In one of these individual actions, the plaintiffs have filed a notice of appeal to the Second Circuit Court of Appeals. Oral argument in that appeal is expected to occur in 2016. In the other individual action, no appeal has been filed.

Bickerstaff v. SunTrust Bank
This case was filed in the Fulton County State Court on July 12, 2010, and an amended complaint was filed on August 9, 2010. Plaintiff asserts that all overdraft fees charged to his account which related to debit card and ATM transactions are actually interest charges and therefore subject to the usury laws of Georgia. Plaintiff has brought claims for violations of civil and criminal usury laws, conversion, and money had and received, and purports to bring the action on behalf of all Georgia citizens who incurred such overdraft fees within the four years before the complaint was filed where the overdraft fee resulted in an interest rate being charged in excess of the usury rate. The Bank filed a motion to compel arbitration and on March 16, 2012, the Court entered an order holding that the Bank's arbitration provision is enforceable but that the named plaintiff in the case had opted out of that provision pursuant to its terms. The Court explicitly stated that it was not ruling at that time on the question of whether the named plaintiff could have opted out for the putative class members. The Bank filed an appeal of this decision, but this appeal was dismissed based on a finding that the appeal was prematurely granted. On April 8, 2013, the plaintiff filed a motion for class certification and that motion was denied on February 19, 2014. Plaintiff appealed the denial of class certification and on September 8, 2015, the Georgia Supreme Court agreed to hear the appeal.
Putative ERISA Class Actions
Company Stock Class Action
Beginning in July 2008, the Company and certain officers, directors, and employees of the Company were named in a putative class action alleging that they breached their fiduciary duties under ERISA by offering the Company's common stock as an investment option in the SunTrust Banks, Inc. 401(k) Plan (the “Plan”). The plaintiffs purport to represent all current and former Plan participants who held the Company stock in their Plan accounts from May 2007 to the present and seek to recover alleged losses these participants supposedly incurred as a result of their investment in Company stock.
This case was originally filed in the U.S. District Court for the Southern District of Florida but was transferred to the U.S. District Court for the Northern District of Georgia, Atlanta Division, (the “District Court”) in November 2008. On October 26, 2009, an amended complaint was filed. On December 9, 2009, defendants filed a motion to dismiss the amended complaint. On October 25, 2010, the District Court granted in part and denied in part defendants' motion to dismiss the amended complaint.
On April 14, 2011, the U.S. Court of Appeals for the Eleventh Circuit (“the Circuit Court”) granted defendants and plaintiffs permission to pursue interlocutory review in separate appeals. The Circuit Court subsequently stayed these appeals pending decision of a separate appeal involving The Home Depot in which substantially similar issues are presented. On May 8, 2012, the Circuit Court decided this appeal in favor of The Home Depot. On March 5, 2013, the Circuit Court issued an order remanding the case to the District Court for further proceedings in light of its decision in The Home Depot case. On September 26, 2013, the District Court granted the defendants' motion to dismiss plaintiffs' claims. Plaintiffs filed an appeal of this decision in the Circuit Court. Subsequent to the filing of this appeal, the U.S. Supreme Court decided Fifth Third Bancorp v. Dudenhoeffer, which held that employee stock ownership plan fiduciaries receive no presumption of prudence with respect to employer stock plans. The Circuit Court remanded the case back to the District Court for further proceedings in light of Dudenhoeffer. On June 18, 2015, the Court entered an order granting in part and denying in part the Company’s motion to dismiss. The discovery process has begun.

Mutual Funds Class Actions
On March 11, 2011, the Company and certain officers, directors, and employees of the Company were named in a putative class action alleging that they breached their fiduciary duties under ERISA by offering certain STI Classic Mutual Funds as investment options in the Plan. The plaintiffs purport to represent all current and former Plan participants who held the STI Classic Mutual Funds in their Plan accounts from April 2002 through December 2010 and seek to recover alleged losses these Plan participants supposedly incurred as a result of their investment in the STI Classic Mutual Funds. This action is pending in the U.S. District Court for the Northern District of Georgia, Atlanta Division (the “District Court”). On June 6, 2011, plaintiffs filed an amended complaint, and, on June 20, 2011, defendants filed a motion to dismiss the amended complaint. On March 12, 2012, the Court granted in part and denied in part the motion to dismiss. The Company filed a subsequent motion to dismiss the remainder of the case on the ground that the Court lacked subject matter jurisdiction over the remaining claims. On October 30, 2012, the Court dismissed all claims in this action. Immediately thereafter, plaintiffs' counsel initiated a substantially similar lawsuit against the Company naming two new plaintiffs and also filed an appeal of the dismissal with the U.S. Court of Appeals for the Eleventh Circuit. The Company filed a motion to dismiss in the new action and this motion was granted. On February 26, 2014, the U.S. Court of Appeals for the Eleventh Circuit upheld the District Court's dismissal. On March 18, 2014, the plaintiffs' counsel filed a motion for reconsideration with the Eleventh Circuit. On August 26, 2014, plaintiffs in the original action filed a Motion for Consolidation of Appeals requesting that the Court consider this appeal jointly with the appeal in the second action. This motion was granted on October 9, 2014 and plaintiffs filed their consolidated appeal on December 16, 2014.
On June 27, 2014, the Company and certain current and former officers, directors, and employees of the Company were named in another putative class action alleging breach of fiduciary duties associated with the inclusion of STI Classic Mutual Funds as investment options in the Plan. This case, Brown, et al. v. SunTrust Banks, Inc., et al., was filed in the U.S. District Court for the District of Columbia. On September 3, 2014, the U.S. District Court for the District of Columbia issued an order transferring the case to the U.S. District Court for the Northern District of Georgia. On November 12, 2014, the Court granted plaintiffs’ motion to stay this case until the U.S. Supreme Court issues a decision in Tibble v. Eidson International. On May 18, 2015, the U.S. Supreme Court decided Tibble and held that plan fiduciaries have a duty, separate and apart from investment selection, to monitor and remove imprudent investments.
After Tibble, the cases pending on appeal were remanded to the District Court.

Intellectual Ventures II v. SunTrust Banks, Inc. and SunTrust Bank
This action was filed in the U.S. District Court for the Northern District of Georgia on July 24, 2013. Plaintiff alleges that SunTrust violates one or more of several patents held by plaintiff in connection with SunTrust’s provision of online banking services and other systems and services. Plaintiff seeks damages for alleged patent infringement of an unspecified amount, as well as attorney’s fees and expenses. The matter was stayed on October 7, 2014 pending inter partes review of a number of the claims asserted against SunTrust.

Consent Order with the Federal Reserve
On April 13, 2011, SunTrust, SunTrust Bank, and STM entered into a Consent Order with the FRB in which SunTrust, SunTrust Bank, and STM agreed to strengthen oversight of, and improve risk management, internal audit, and compliance programs concerning the residential mortgage loan servicing, loss mitigation, and foreclosure activities of STM.
On July 25, 2014, the FRB imposed a $160 million civil money penalty as a result of the FRB’s review of the Company’s residential mortgage loan servicing and foreclosure processing practices that preceded the Consent Order. The Company expects to satisfy the entirety of this assessed penalty by providing consumer relief and certain cash payments as contemplated by the settlement with the U.S. and the States Attorneys' General regarding certain mortgage servicing claims, discussed below at “United States Mortgage Servicing Settlement.” SunTrust continues its engagement with the FRB to demonstrate compliance with its commitments under the Consent Order.
United States Mortgage Servicing Settlement
In the second quarter of 2014, STM and the U.S., through the DOJ, HUD, and Attorneys General for several states, reached a final settlement agreement related to the National Mortgage Servicing Settlement. The settlement agreement became effective on September 30, 2014 when the court entered the Consent Judgment. Pursuant to the settlements, STM made $50 million in cash payments and committed to provide $500 million of consumer relief by the fourth quarter of 2017 and to implement certain mortgage servicing standards. While subject to confirmation by the independent Office of Mortgage Settlement Oversight (“OMSO”) appointed to review and certify compliance with the provisions of the settlement, the Company believes it has fulfilled its consumer relief commitments. STM also implemented all of the prescribed servicing standards within the required timeframes. Compliance with the servicing standards continues to be monitored, tested, and reported quarterly by an internal review group and semi-annually by the OMSO. As a result, the Company does not expect to incur additional costs in satisfying its consumer relief obligations or implementation of the servicing standards associated with the settlement.

DOJ Investigation of GSE Loan Origination Practices
In January 2014, STM received notice from the DOJ of an investigation regarding the origination and underwriting of single family residential mortgage loans sold by STM to Fannie Mae and Freddie Mac. The DOJ and STM have not yet engaged in any material dialogue about how this matter may proceed and no allegations have been raised against STM. STM continues to cooperate with the investigation.

Mortgage Modification Investigation
In the third quarter of 2014, STM resolved claims by the United States Attorney’s Office for the Western District of Virginia and the Office of the Special Inspector General for the Troubled Asset Relief Program relating to STM's administration of HAMP. Pursuant to the settlement, the Company paid $46 million, including $20 million to fund housing counseling for homeowners, $10 million in restitution to Fannie Mae and Freddie Mac, and $16 million to the U.S. Treasury, and transferred its minimum consumer remediation obligation of $179 million (which may increase to a maximum of $274 million) to the required deposit account to be controlled by a third party claims administrator. The Company incurred a $204 million pre-tax charge in the second quarter of 2014 in connection with this matter, which included its estimate of the consumer remediation obligation. STM continues to cooperate with the government and the claims administrator regarding administration of the consumer remediation payment process, which currently is expected to resolve in early 2016. The Company does not currently anticipate it will exceed the $179 million minimum consumer remediation obligation.
Residential Funding Company, LLC v. SunTrust Mortgage, Inc.
STM has been named as a defendant in a complaint filed December 17, 2013 in the Southern District of New York by Residential Funding Company, LLC ("RFC"), a Chapter 11 debtor-affiliate of GMAC Mortgage, LLC, alleging breaches of representations and warranties made in connection with loan sales and seeking indemnification against losses allegedly suffered by RFC as a result of such alleged breaches. The case was transferred to the United States Bankruptcy Court for the Southern District of New York. The litigation remains active in the Bankruptcy Court and discovery has commenced.

SunTrust Mortgage Reinsurance Class Actions
STM and Twin Rivers Insurance Company ("Twin Rivers") have been named as defendants in two putative class actions alleging that the companies entered into illegal “captive reinsurance” arrangements with private mortgage insurers. More specifically, plaintiffs allege that SunTrust’s selection of private mortgage insurers who agree to reinsure with Twin Rivers certain loans referred to them by SunTrust results in illegal “kickbacks” in the form of the insurance premiums paid to Twin Rivers. Plaintiffs contend that this arrangement violates the Real Estate Settlement Procedures Act (“RESPA”) and results in unjust enrichment to the detriment of borrowers. The first of these cases, Thurmond, Christopher, et al. v. SunTrust Banks, Inc. et al., was filed in February 2011 in the U.S. District Court for the Eastern District of Pennsylvania. This case was stayed by the Court pending the outcome of Edwards v. First American Financial Corporation, a captive reinsurance case that was pending before the U.S. Supreme Court at the time. The second of these cases, Acosta, Lemuel & Maria Ventrella et al. v. SunTrust Bank, SunTrust Mortgage, Inc., et al., was filed in the U.S. District Court for the Central District of California in December 2011. This case was stayed pending a decision in the Edwards case also. In June 2012, the U.S. Supreme Court withdrew its grant of certiorari in Edwards and, as a result, the stays in these cases were lifted. SunTrust has filed a motion to dismiss the Thurmond case which was granted in part and denied in part, allowing limited discovery surrounding the argument that the statute of limitations for certain claims should be equitably tolled. Thurmond has been stayed pending a ruling in a similar case currently before the Third Circuit. The Acosta plaintiffs have voluntarily dismissed their case.

United States Attorney’s Office for the Southern District of New York Foreclosure Expense Investigation
STM has been cooperating with the United States Attorney's Office for the Southern District of New York (the "Southern District") in a broad-based industry investigation regarding claims for foreclosure-related expenses charged by law firms in connection with the foreclosure of loans guaranteed or insured by Fannie Mae, Freddie Mac, or FHA. The investigation relates to a private litigant qui tam lawsuit filed under seal and remains in early stages. The Southern District has not yet advised STM how it will proceed in this matter. The Southern District and STM engaged in dialogue regarding potential resolution of this matter as part of the National Mortgage Servicing Settlement, but were unable to reach agreement.
Business Segment Reporting
Business Segment Reporting
NOTE 20 - BUSINESS SEGMENT REPORTING
The Company measures business activity across three segments: Consumer Banking and Private Wealth Management, Wholesale Banking, and Mortgage Banking, with functional activities included in Corporate Other. The business segments are determined based on the products and services provided or the type of client served, and they reflect the manner in which financial information is evaluated by management. The following is a description of the segments and their composition.
The Consumer Banking and Private Wealth Management segment is made up of two primary businesses: Consumer Banking and Private Wealth Management.
•
Consumer Banking provides services to consumers and branch-managed small business clients through an extensive network of traditional and in-store branches, ATMs, the internet (www.suntrust.com), mobile banking, and telephone (1-800-SUNTRUST). Financial products and services offered to consumers and small business clients include deposits, home equity lines and loans, credit lines, indirect auto, student lending, bank card, other lending products, and various fee-based services. Consumer Banking also serves as an entry point for clients and provides services for other lines of business.
•
PWM provides a full array of wealth management products and professional services to both individual and institutional clients including loans, deposits, brokerage, professional investment management, and trust services to clients seeking active management of their financial resources. Institutional clients are served by the Institutional Investment Solutions business. Discount/online and full-service brokerage products are offered to individual clients through STIS. PWM also includes GenSpring, which provides family office solutions to ultra-high net worth individuals and their families. Utilizing teams of multi-disciplinary specialists with expertise in investments, tax, accounting, estate planning, and other wealth management disciplines, GenSpring helps families manage and sustain wealth across multiple generations.

The Wholesale Banking segment includes the following four businesses:
•
CIB delivers comprehensive capital markets solutions, including advisory, capital raising, and financial risk management, with the goal of serving the needs of both public and private companies in the Wholesale Banking segment and PWM business. Investment Banking and Corporate Banking teams within CIB serve clients across the nation, offering a full suite of traditional banking and investment banking products and services to companies with annual revenues typically greater than $150 million. Investment Banking serves select industry segments including consumer and retail, energy, financial services, healthcare, industrials, and technology, media and communications. Corporate Banking serves clients across diversified industry sectors based on size, complexity, and frequency of capital markets issuance. Also managed within CIB is the Equipment Finance Group, which provides lease financing solutions (through SunTrust Equipment Finance & Leasing).
•
Commercial & Business Banking offers an array of traditional banking products, including lending, cash management and investment banking solutions via STRH to commercial clients (generally those with revenues $1 million to $150 million), not-for-profit organizations, and governmental entities, as well as auto dealer financing (floor plan inventory financing). Also managed within Commercial & Business Banking is the Premium Assignment Corporation, which provides corporate insurance premium financing solutions.
•
Commercial Real Estate provides a full range of financial solutions for commercial real estate developers, owners, and investors, including construction, mini-perm, and permanent real estate financing, as well as tailored financing and equity investment solutions via STRH. The Institutional Real Estate team targets relationships with institutional advisors, private funds, and insurance companies and the Regional team focuses on real estate owners and developers through a regional delivery structure. Commercial Real Estate also offers tailored financing and equity investment solutions for community development and affordable housing projects through STCC, with particular expertise in Low Income Housing Tax Credits and New Market Tax Credits.
•
Treasury & Payment Solutions provides all SunTrust business clients with services required to manage their payments and receipts, combined with the ability to manage and optimize their deposits across all aspects of their business. Treasury & Payment Solutions operates all electronic and paper payment types, including card, wire transfer, ACH, check, and cash. It also provides clients the means to manage their accounts electronically online, both domestically and internationally.
Mortgage Banking offers residential mortgage products nationally through its retail and correspondent channels, as well as via the internet (www.suntrust.com) and by telephone (1-800-SUNTRUST). These products are either sold in the secondary market, primarily with servicing rights retained, or held in the Company’s loan portfolio. Mortgage Banking also services loans for itself and for other investors.
Corporate Other includes management of the Company’s investment securities portfolio, long-term debt, end user derivative instruments, short-term liquidity and funding activities, balance sheet risk management, and most real estate assets. Additionally, it includes Enterprise Information Services, which is the primary information technology and operations group; Corporate Real Estate, Marketing, SunTrust Online, Human Resources, Finance, Corporate Risk Management, Legal and Compliance, Communications, Procurement, and Executive Management. The financial results of RidgeWorth, including the gain on sale, are reflected in the Corporate Other segment for the years ended December 31, 2014 and 2013. Prior to the sale of RidgeWorth in the second quarter of 2014, RidgeWorth's financial performance was reported in the Wholesale Banking segment. See Note 2, "Acquisitions/Dispositions," for additional information related to the sale of RidgeWorth.
Because the business segment results are presented based on management accounting practices, the transition to the consolidated results, which are prepared under U.S. GAAP, creates certain differences which are reflected in Reconciling Items. Business segment reporting conventions are described below.
•
Net interest income – Net interest income is presented on an FTE basis to make income from tax-exempt assets comparable to other taxable products. The segment results reflect matched maturity funds transfer pricing, which ascribes credits or charges based on the economic value or cost created by the assets and liabilities of each segment. The mismatch between funds credits and funds charges at the segment level resides in Reconciling Items. The change in this mismatch is generally attributable to corporate balance sheet management strategies.
•
Provision/(benefit) for credit losses – Represents net charge-offs by segment combined with an allocation to the segments of the provision/(benefit) attributable to each segment's quarterly change in the ALLL and unfunded commitments reserve balances.
•
Provision/(benefit) for income taxes – Calculated using a blended income tax rate for each segment. This calculation includes the impact of various adjustments, such as the reversal of the FTE gross up on tax-exempt assets, tax adjustments, and credits that are unique to each segment. The difference between the calculated provision/(benefit) for income taxes at the segment level and the consolidated provision/(benefit) for income taxes is reported in Reconciling Items.
The segment’s financial performance is comprised of direct financial results, as well as various allocations that for internal management reporting purposes provide an enhanced view of the segment’s financial performance. The internal allocations include the following:
•
Operational costs – Expenses are charged to the segments based on various statistical volumes multiplied by activity based cost rates. As a result of the activity based costing process, residual expenses are also allocated to the segments. The recoveries for the majority of these costs are reported in Corporate Other.
•
Support and overhead costs – Expenses not directly attributable to a specific segment are allocated based on various drivers (e.g., number of equivalent employees, number of PCs/Laptops, and net revenue). The recoveries for these allocations are reported in Corporate Other.
•
Sales and referral credits – Segments may compensate another segment for referring or selling certain products. The majority of the revenue resides in the segment where the product is ultimately managed.
The application and development of management reporting methodologies is a dynamic process and is subject to periodic enhancements. The implementation of these enhancements to the internal management reporting methodology may materially affect the results disclosed for each segment, with no impact on consolidated results. Whenever significant changes to management reporting methodologies take place, the impact of these changes is quantified and prior period information is reclassified wherever practicable.

Significant Accounting Policies (Policies)
Accounting Policies Recently Adopted and Pending Accounting Pronouncements
Accounting Standards Not Yet Adopted
The following table provides a brief description of accounting standards that have been issued, but are not yet adopted, that could have a material effect on the Company's financial statements:
Standard
Description
Date of Adoption
Effect on the Financial Statements or Other Significant Matters
ASU 2014-09, Revenue from Contracts with Customers
The ASU supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition, and most industry-specific guidance throughout the Industry Topics of the Codification. The core principle of the ASU is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU may be adopted either retrospectively or on a modified retrospective basis to new contracts and existing contracts with remaining performance obligations as of the effective date.
January 1, 2018
(early adoption permitted beginning January 1, 2017)
The Company is continuing to evaluate the alternative methods of adoption and the anticipated effects on the financial statements and related disclosures.

ASU 2016-01, Recognition and Measurement of Financial Assets and Liabilities
The ASU addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The main provisions require investments in equity securities to be measured at fair value through net income, unless they qualify for a practicability exception, and require fair value changes arising from changes in instrument-specific credit risk for financial liabilities that are measured under the fair value option to be recognized in other comprehensive income. With the exception of disclosure requirements that would be adopted prospectively, the ASU must be adopted on a modified retrospective basis.
January 1, 2018
(early adoption permitted beginning January 1, 2016 or 2017 for the provision related to changes in instrument-specific credit risk for financial liabilities under the fair value option)
The Company is early adopting the provision related to changes in instrument-specific credit risk beginning January 1, 2016, which will result in an immaterial reclassification from retained earnings to OCI. The prospective impact of this provision on the financial statements is a function of the principal amount of financial liabilities under the fair value option and changes in the Company's credit spreads. The Company is evaluating the impact of the remaining provisions of this ASU on the financial statements and related disclosures; however, the impact is not expected to be material.
Pending Accounting Pronouncements

ASU 2015-02, Amendments to the Consolidation Analysis
The ASU rescinds the indefinite deferral of previous amendments to ASC Topic 810 for certain entities and amends components of the consolidation analysis under ASC Topic 810, including evaluating limited partnerships and similar legal entities, evaluating fees paid to a decision maker or service provider as a variable interest, the effects of fee arrangements and/or related parties on the primary beneficiary determination and investment fund specific matters. The ASU may be adopted either retrospectively or on a modified retrospective basis.
January 1, 2016
The Company will adopt this ASU on a modified retrospective basis. The Company is continuing to evaluate the impact of this ASU on the financial statements and related disclosures; however, adoption is not expected to materially impact the Company's financial position, results of operations, or EPS.
Employee Benefit Plans Employee Benefits - Policies (Policies)
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]
The Company sponsors various short-term incentive and LTI plans for eligible employees, which may be delivered through various programs, such as RSUs, restricted stock, performance stock units, and AIP and LTI cash. All incentive awards are subject to clawback provisions. Awards for performance stock units vest over a period of three years and are paid in cash. AIP is the Company's short-term cash incentive plan for key employees that provides for potential annual cash awards based on the Company's performance and/or the achievement of business unit and individual performance objectives. Awards under the LTI cash plan generally cliff vest after three years from the date of the award and are paid in cash. Compensation expense for incentive plans with cash payouts was $245 million, $203 million, and $150 million for the years ended December 31, 2015, 2014, and 2013, respectively.
Stock-Based Compensation
The Company provides stock-based awards through the 2009 Stock Plan under which the Compensation Committee of the Board of Directors has the authority to grant stock options, stock appreciation rights, restricted stock, performance stock units, and RSUs to key employees of the Company. Award vesting may be conditional based upon individual, business unit, Company, and/or performance relative to peer group metrics.
As amended and restated effective January 1, 2014, following approval by the Compensation Committee of the Board, shareholders approved an amendment to the 2009 Stock Plan to remove the sub-limit on shares available for grant that may be issued as restricted stock or RSUs. Accordingly, all 17 million remaining authorized shares previously under the Plan became available for grant as stock options, stock appreciation rights, restricted stock, or RSUs. Prior to the amendment, only a portion of such shares were available to be granted as either restricted stock or RSUs. At December 31, 2015, approximately 16 million shares were available for grant.
Shares or units of restricted stock may be granted to employees and directors. Generally, grants to employees either cliff vest after three years or vest pro-rata annually over three years. Restricted stock grants may be subject to one or more criteria, including employment, performance, or other conditions as established by the Compensation Committee at the time of grant. Any shares of restricted stock that are forfeited will again become available for issuance under the Stock Plan. An employee or director has the right to vote the shares of restricted stock after grant until they are forfeited. Compensation cost for restricted stock and RSUs is generally equal to the fair market value of the shares on the grant date of the award and is amortized to compensation expense over the vesting period. Dividends are paid on awarded, unvested restricted stock.
The Company accrues and reinvests dividends in equivalent shares of SunTrust common stock for unvested RSU awards, which are paid out when the underlying RSU award vests. Generally, RSU awards are classified as equity. However, during 2012 there were 574,257 RSUs granted that were classified as a liability because the grant date had not been achieved as defined under U.S. GAAP. These awards were granted with a fair value of $21.67 per unit on the grant date. The balance of RSUs classified as a liability at December 31, 2015 and 2014 was $23 million and $21 million, respectively.
Consistent with the Company's 2014 decision to discontinue the issuance of stock options, no stock options were granted during the years ended December 31, 2015 and 2014. For options issued in 2013 the fair value of option grants was estimated on the date of grant using the Black-Scholes option pricing model based on the assumptions presented in the following table.

1 Assumptions are not applicable ("N/A") as the Company discontinued the issuance of stock options and no stock options were granted for the years ended December 31, 2015 and 2014.
The Company used the projected dividend to be paid as the dividend yield assumption. The expected stock price volatility represented the implied volatility of SunTrust stock. The risk-free interest rate was derived from the U.S. Treasury yield curve in effect at the time of grant based on the expected life of the option. The expected life of options represented the period of time that the stock options were expected to be outstanding and was derived from historical data that was used to evaluate patterns such as stock option exercise and employee termination.
Stock options were granted at an exercise price that was no less than the fair market value of a share of SunTrust common stock on the grant date and were either tax-qualified incentive stock options or non-qualified stock options. Stock options typically vest pro-rata over three years and generally have a maximum contractual life of ten years. Upon exercise, shares are generally issued from treasury stock. The weighted average fair value of options granted during year ended December 31, 2013 was $7.37 per share.

(b) 

The following methods and assumptions were used by the Company in estimating the fair value of financial instruments:
(a)
Cash and cash equivalents are valued at their carrying amounts, which are reasonable estimates of fair value due to the relatively short period to maturity of the instruments.
(b)
Trading assets and derivative instruments, securities AFS, and trading liabilities and derivative instruments that are classified as level 1 are valued based on quoted market prices. For those instruments classified as level 2 or 3, refer to the respective valuation discussions within this footnote.
(c)
LHFS are generally valued based on observable current market prices or, if quoted market prices are not available, quoted market prices of similar instruments. Refer to the LHFS section within this footnote for further discussion. When valuation assumptions are not readily observable in the market, instruments are valued based on the best available data to approximate fair value. This data may be internally developed and considers risk premiums that a market participant would require under then-current market conditions.
(d)
LHFI fair values are based on a hypothetical exit price, which does not represent the estimated intrinsic value of the loan if held for investment. The assumptions used are expected to approximate those that a market participant purchasing the loans would use to value the loans, including a market risk premium and liquidity discount. Estimating the fair value of the loan portfolio when loan sales and trading markets are illiquid or nonexistent requires significant judgment.
Generally, the Company measures fair value for LHFI based on estimated future discounted cash flows using current origination rates for loans with similar terms and credit quality, which derived an estimated value of 101% and 100% on the loan portfolio’s net carrying value at December 31, 2015 and 2014, respectively. The value derived from origination rates likely does not represent an exit price; therefore, an incremental market risk and liquidity discount was applied when estimating the fair value of these loans. The discounted value is a function of a market participant’s required yield in the current environment and is not a reflection of the expected cumulative losses on the loans.
(e)
Deposit liabilities with no defined maturity such as DDAs, NOW/money market accounts, and savings accounts have a fair value equal to the amount payable on demand at the reporting date (i.e., their carrying amounts). Fair values for CDs are estimated using a discounted cash flow approach that applies current interest rates to a schedule of aggregated expected maturities. The assumptions used in the discounted cash flow analysis are expected to approximate those that market participants would use in valuing deposits. The value of long-term relationships with depositors is not taken into account in estimating fair values.
(f)
Fair values for short-term borrowings and certain long-term debt are based on quoted market prices for similar instruments or estimated discounted cash flows utilizing the Company’s current incremental borrowing rate for similar types of instruments. For long-term debt that the Company measures at fair value, refer to the respective valuation section within this footnote. For level 3 debt, the terms are unique in nature or there are no similar instruments that can be used to value the instrument without using significant unobservable assumptions. In these situations, the Company reviews current borrowing rates along with the collateral levels that secure the debt in determining an appropriate fair value adjustment.
