Unaudited Condensed Consolidated Financial Statements
 
We prepared the accompanying condensed consolidated financial statements of Ensco plc and subsidiaries (the "Company," "Ensco," "our," "we" or "us") in accordance with accounting principles generally accepted in the United States of America ("GAAP"), pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC") included in the instructions to Form 10-Q and Article 10 of Regulation S-X. The financial information included in this report is unaudited but, in our opinion, includes all adjustments (consisting of normal recurring adjustments) that are necessary for a fair presentation of our financial position, results of operations and cash flows for the interim periods presented. The December 31, 2015 condensed consolidated balance sheet data were derived from our 2015 audited consolidated financial statements, but do not include all disclosures required by GAAP. Certain previously reported amounts have been reclassified to conform to the current year presentation. The preparation of our condensed consolidated financial statements requires us to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, the related revenues and expenses and disclosures of gain and loss contingencies as of the date of the financial statements. Actual results could differ from those estimates.
 
The financial data for the quarters ended March 31, 2016 and 2015 included herein have been subjected to a limited review by KPMG LLP, our independent registered public accounting firm. The accompanying independent registered public accounting firm's review report is not a report within the meaning of Sections 7 and 11 of the Securities Act of 1933, and the independent registered public accounting firm's liability under Section 11 does not extend to it.
 
Results of operations for the quarter ended March 31, 2016 are not necessarily indicative of the results of operations that will be realized for the year ending December 31, 2016. We recommend these condensed consolidated financial statements be read in conjunction with our annual report on Form 10-K for the year ended December 31, 2015 filed with the SEC on February 24, 2016.

New Accounting Pronouncements

In March 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-09, Compensation — Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting ("Update 2016-09"), which simplifies several aspects of accounting for share-based payment transactions including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This update is effective for annual and interim periods beginning after December 15, 2016, with early adoption permitted. Transition methods vary for the related amendments being adopted. We are currently evaluating the effect that Update 2016-09 will have on our condensed consolidated financial statements and related disclosures.

In February 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-02, Leases (Topic 842): Amendments to the FASB Accounting Standards Codification ("Update 2016-02"), which requires an entity to recognize lease assets and lease liabilities on the balance sheet and to disclose key qualitative and quantitative information about the entity's leasing arrangements. This update is effective for annual and interim periods beginning after December 15, 2018, with early adoption permitted. A modified retrospective approach is required. We are currently evaluating the effect that Update 2016-02 will have on our condensed consolidated financial statements and related disclosures.

During 2015, the Financial Accounting Standards Board issued Accounting Standards Update 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs ("Update 2015-03"), as updated by Update 2015-15, Interest - Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements - Amendments to SEC Paragraphs Pursuant to Staff Announcements at June 18, 2015 EITF Meeting ("Update 2015-05"), which require that debt issuance costs related to a recognized debt liability be presented on the balance sheet as a direct deduction from the carrying amount of the related debt liability, consistent with debt discounts. Debt issuance costs related to line-of-credit arrangements may be presented as an asset regardless of whether there are any outstanding borrowings on the arrangement. We adopted Update 2015-03 and Update 2015-15 on a retrospective basis effective January 1, 2016. Accordingly, all debt issuance costs, except for the balance related to our line-of-credit arrangement, were presented as a deduction from the carrying amount of the related debt liability on our condensed consolidated balance sheet for all periods presented. As a result of retrospective application, we reclassified debt issuance costs of $26.5 million on our condensed consolidated balance sheet as of December 31, 2015. There is no impact to the manner in which debt issuance costs are amortized in our consolidated financial statements.

During 2014, the Financial Accounting Standards Board issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers (Topic 606) ("Update 2014-09"), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. In 2015, the Financial Accounting Standards Board voted to delay the effective date one year. Update 2014-09 is now effective for annual and interim periods for fiscal years beginning after December 15, 2017, though companies have an option of adopting the standard for fiscal years beginning after December 15, 2016. During 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations ("Update 2016-08") and Accounting Standards Update 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing ("Update 2016-10"). The amendments in Update 2016-08 and Update 2016-10 do not change the core principle of Update 2014-09 but instead clarify the implementation guidance on principle versus agent considerations and identify performance obligations and the licensing implementation guidance, respectively. Update 2014-09 will replace most existing revenue recognition guidance in U.S. GAAP and may be adopted using a retrospective, modified retrospective or prospective with a cumulative catch-up approach. We are currently evaluating the effect that Update 2014-09 will have on our condensed consolidated financial statements and related disclosures.

Supplemental Executive Retirement Plan Assets
 
Our supplemental executive retirement plans (the "SERP") are non-qualified plans that provide eligible employees an opportunity to defer a portion of their compensation for use after retirement. Assets held in the SERP were marketable securities measured at fair value on a recurring basis using Level 1 inputs and were included in other assets, net, on our condensed consolidated balance sheets. The fair value measurement of assets held in the SERP was based on quoted market prices.
 
Derivatives
 
Our derivatives were measured at fair value on a recurring basis using Level 2 inputs. See "Note 3 - Derivative Instruments" for additional information on our derivatives, including a description of our foreign currency hedging activities and related methodologies used to manage foreign currency exchange rate risk. The fair value measurement of our derivatives was based on market prices that are generally observable for similar assets or liabilities at commonly-quoted intervals.

Our functional currency is the U.S. dollar. As is customary in the oil and gas industry, a majority of our revenues are denominated in U.S. dollars; however, a portion of the revenues earned and expenses incurred by certain of our subsidiaries are denominated in currencies other than the U.S. dollar ("foreign currencies"). These transactions are remeasured in U.S. dollars based on a combination of both current and historical exchange rates. We use foreign currency forward contracts to reduce our exposure to various market risks, primarily foreign currency exchange rate risk.
 
All of our derivatives were recorded on our condensed consolidated balance sheets at fair value. Derivatives subject to legally enforceable master netting agreements were not offset in our condensed consolidated balance sheets. Accounting for the gains and losses resulting from changes in the fair value of derivatives depends on the use of the derivative and whether it qualifies for hedge accounting.  Net assets of $100,000 and net liabilities of $19.7 million associated with our derivatives were included on our condensed consolidated balance sheets as of March 31, 2016 and December 31, 2015, respectively.  All of our derivatives mature during the next 18 months.  See "Note 2 - Fair Value Measurements" for additional information on the fair value measurement of our derivatives.

We utilize cash flow hedges to hedge forecasted foreign currency denominated transactions, primarily to reduce our exposure to foreign currency exchange rate risk associated with contract drilling expenses and capital expenditures denominated in various currencies. As of March 31, 2016, we had cash flow hedges outstanding to exchange an aggregate $264.2 million for various foreign currencies, including $130.6 million for British pounds, $40.6 million for Brazilian reals, $38.5 million for Australian dollars, $31.7 million for euros, $10.0 million for Singapore dollars, and $12.8 million for other currencies.

Gains and losses, net of tax, on derivatives designated as cash flow hedges included in our condensed consolidated statements of income and comprehensive income for the quarters ended March 31, 2016 and 2015 were as follows (in millions):

 
Gain (Loss) Recognized in Other Comprehensive Income ("OCI") (Effective Portion)

Changes in the fair value of cash flow hedges are recorded in AOCI.  Amounts recorded in AOCI associated with cash flow hedges are subsequently reclassified into contract drilling, depreciation or interest expense as earnings are affected by the underlying hedged forecasted transaction.

(2)
Gains and losses recognized in income for ineffectiveness and amounts excluded from effectiveness testing were included in other, net, in our condensed consolidated statements of income.

(3)
Losses on interest rate lock derivatives reclassified from AOCI into income (effective portion) were included in interest expense, net, in our condensed consolidated statements of income.

(4) 
During 2016, $6.0 million of losses were reclassified from AOCI into contract drilling expense and $200,000 of gains were reclassified from AOCI into depreciation expense in our condensed consolidated statement of income. During the prior year quarter, $5.1 million of losses were reclassified from AOCI into contract drilling expense and $200,000 of gains were reclassified from AOCI into depreciation expense in our condensed consolidated statement of income.

We have net assets and liabilities denominated in numerous foreign currencies and use various methods to manage our exposure to foreign currency exchange rate risk. We predominantly structure our drilling contracts in U.S. dollars, which significantly reduces the portion of our cash flows and assets denominated in foreign currencies. We occasionally enter into derivatives that hedge the fair value of recognized foreign currency denominated assets or liabilities but do not designate such derivatives as hedging instruments. In these situations, a natural hedging relationship generally exists whereby changes in the fair value of the derivatives offset changes in the fair value of the underlying hedged items. As of March 31, 2016, we held derivatives not designated as hedging instruments to exchange an aggregate $135.4 million for various foreign currencies, including $76.7 million for euros, $12.1 million for Swiss francs, $10.9 million for British pounds, $8.8 million for Indonesian rupiah, $8.4 million for Brazilian reals, $8.0 million for Mexican pesos, $6.2 million for Australian dollars and $4.3 million for other currencies.
     
Net gains of $4.4 million and net losses of $13.5 million associated with our derivatives not designated as hedging instruments were included in other, net, in our condensed consolidated statements of income for the quarters ended March 31, 2016 and 2015, respectively.

As of March 31, 2016, the estimated amount of net losses associated with derivative instruments, net of tax, that would be reclassified into earnings during the next twelve months totaled $3.6 million.

We compute basic and diluted earnings per share ("EPS") in accordance with the two-class method. Net income attributable to Ensco used in our computations of basic and diluted EPS is adjusted to exclude net income allocated to non-vested shares granted to our employees and non-employee directors. Weighted-average shares outstanding used in our computation of diluted EPS is calculated using the treasury stock method and excludes non-vested shares.

Shareholders' Equity

We filed an automatically effective shelf registration statement on Form S-3 with the U.S. Securities and Exchange Commission on January 15, 2015, which provides us the ability to issue debt securities, equity securities, guarantees and/or units of securities in one or more offerings. The registration statement, as amended, expires in January 2018.

On April 20, 2016, we closed an underwritten public offering of 65,550,000 Class A ordinary shares at $9.25 per share, inclusive of shares purchased under an underwriters' option. We received net proceeds from the offering of approximately $585.5 million.

During the second quarter, we expect to recognize a pre-tax gain from debt extinguishment of approximately $245.0 million related to the Tender Offers, net of discounts, premiums, debt issuance costs and transaction costs.

After giving effect to the Tender Offers, our next debt maturity is $454.3 million during 2019, followed by $759.9 million, $857.5 million, $623.3 million and $669.3 million during 2020, 2021, 2024 and 2025, respectively.

Revolving Credit

We have a $2.25 billion senior unsecured revolving credit facility with a syndicate of banks to be used for general corporate purposes with a term expiring on September 30, 2019 (the "Credit Facility"). Advances under the Credit Facility bear interest at Base Rate or LIBOR plus an applicable margin rate, depending on our credit ratings. We are required to pay a quarterly commitment fee on the undrawn portion of the $2.25 billion commitment, which is also based on our credit ratings.

In February 2016, Moody’s announced a downgrade of our credit rating to B1, which is below investment grade. This downgrade has resulted in an increase in our applicable margin rate by 0.25% per annum and our quarterly commitment fee by 0.075% per annum under our Credit Facility.  Following the February 2016 downgrade, the applicable margin rates are 0.50% per annum for Base Rate advances and 1.50% per annum for LIBOR advances. Also, our quarterly commitment fee is 0.225% per annum on the undrawn portion of the $2.25 billion commitment.  Any further downgrades will not impact our applicable margin rate on borrowings or our quarterly commitment fee. We have limited or no access to the commercial paper market as a result of our recent downgrade.

Our access to credit and capital markets depends on the credit ratings assigned to our debt by independent credit rating agencies. There can be no assurance that we will be able to maintain our credit ratings, and any additional actual or anticipated downgrades in our credit ratings, including any announcement that our ratings are under review for a downgrade, could limit our available options when accessing credit and capital markets, or when restructuring or refinancing our debt. In addition, future financings or refinancings may result in higher borrowing costs and require more restrictive terms and covenants.


The Credit Facility requires us to maintain a total debt to total capitalization ratio that is less than or equal to 60%. The Credit Facility also contains customary restrictive covenants, including, among others, prohibitions on creating, incurring or assuming certain debt and liens; entering into certain merger arrangements; selling, leasing, transferring or otherwise disposing of all or substantially all of our assets; making a material change in the nature of the business; and entering into certain transactions with affiliates. We have the right, subject to receipt of commitments from new or existing lenders, to increase the commitments under the Credit Facility to an aggregate amount of up to $2.75 billion and to extend the term of the Credit Facility by one year on up to two occasions.

As of March 31, 2016, we were in compliance in all material respects with our covenants under the Credit Facility. We had no amounts outstanding under the Credit Facility as of March 31, 2016 and December 31, 2015.
Discontinued Operations (Notes)
Discontinued Operations
Discontinued Operations
    
During 2014, ENSCO 5001, ENSCO 5002, ENSCO 6000, ENSCO 7500, ENSCO DS-2, ENSCO 58 and ENSCO 90 were removed from our portfolio of marketed rigs and reclassified as discontinued operations. The operating results from these rigs were included in loss from discontinued operations, net, in our condensed consolidated statements of income for the quarters ended March 31, 2016 and 2015.

In April 2016, we sold ENSCO 6000 for net proceeds of $600,000. We will recognize the proceeds from the sale and pre-tax loss of $150,000 in connection with the disposal during the second quarter.
    
In December 2015, we sold ENSCO 5001 for net proceeds of $2.4 million. In June 2015, we sold ENSCO 5002 for net proceeds of $1.6 million. The remaining rigs are being actively marketed and were classified as held-for-sale on our March 31, 2016 condensed consolidated balance sheet.

In September 2014, we sold ENSCO 93, a jackup contracted to Pemex. In connection with the sale, we executed a charter agreement with the purchaser to continue operating the rig for the remainder of the Pemex contract, which ended in July 2015, less than one year from the date of sale. Our management services following the sale did not constitute significant ongoing involvement and therefore, ENSCO 93 operating results were included in loss from discontinued operations, net, in our condensed consolidated statement of income for the quarter ended March 31, 2015.

Income Taxes
Income Taxes
Income Taxes
 
Our consolidated effective income tax rate for the quarter ended March 31, 2016 was 28.7% as compared to 19.1% in the prior year quarter. Excluding the impact of discrete tax items, our consolidated effective income tax rate for the quarters ended March 31, 2016 and 2015 was 27.3% and 17.5%, respectively. The increase is primarily attributable to an increase in the relative components of our estimated 2016 earnings, excluding discrete items, generated in tax jurisdictions with higher tax rates.

Discrete tax expenses for the quarters ended March 31, 2016 and 2015 were primarily attributable to the recognition of liabilities for unrecognized tax benefits associated with tax positions taken in prior years.

Brazil Internal Investigation

Pride International, Inc. (“Pride”), a company we acquired in 2011, commenced drilling operations in Brazil in 2001. In 2008, Pride entered into a drilling services agreement with Petrobras (the "DSA") for ENSCO DS-5, a drillship ordered from Samsung Heavy Industries, a shipyard in South Korea ("SHI"). Beginning in 2006, Pride conducted periodic compliance reviews of its business with Petrobras, and, after the acquisition of Pride, Ensco conducted similar compliance reviews, the most recent of which commenced in early 2015 after media reports were released regarding ongoing investigations of various kickback and bribery schemes in Brazil involving Petrobras.

While conducting our compliance review, we became aware of an internal audit report by Petrobras alleging irregularities in relation to the DSA. Upon learning of the Petrobras internal audit report, our Audit Committee appointed independent counsel to lead an investigation into the alleged irregularities. Further, in June and July 2015, we voluntarily contacted the SEC and the DOJ, respectively, to advise them of this matter and our Audit Committee’s investigation. Independent counsel, under the direction of our Audit Committee, has substantially completed its investigation by reviewing and analyzing available documents and correspondence and interviewing current and former employees involved in the DSA negotiations and the negotiation of the ENSCO DS-5 construction contract with SHI (the "DS-5 Construction Contract").

To date, our Audit Committee has found no evidence that Pride or Ensco or any of their current or former employees were aware of or involved in any wrongdoing, and our Audit Committee has found no evidence linking Ensco or Pride to any illegal acts committed by our former marketing consultant, who provided services to Pride and Ensco in connection with the DSA. Independent counsel has continued to provide the SEC and DOJ with updates throughout the investigation, including detailed briefings regarding its investigation and findings. On December 21, 2015, we entered into a one-year tolling agreement with the DOJ. On March 7, 2016, we entered into a one-year tolling agreement with the SEC.

Subsequent to initiating our Audit Committee investigation, Brazilian court documents connected to the prosecution of former Petrobras directors and employees as well as certain other third parties, including our former marketing consultant, referenced the alleged irregularities cited in the Petrobras internal audit report. Our former marketing consultant has entered into a plea agreement with the Brazilian authorities. On January 10, 2016, Brazilian authorities filed an indictment against a former Petrobras director. This indictment states that the former Petrobras director received bribes paid out of proceeds from a brokerage agreement entered into for purposes of intermediating a drillship construction contract between SHI and Pride, which we believe to be the DS-5 Construction Contract. The parties to the brokerage agreement were a company affiliated with a person acting on behalf of the former Petrobras director, a company affiliated with our former marketing consultant, and SHI. The indictment alleges that amounts paid by SHI under the brokerage agreement ultimately were used to pay bribes to the former Petrobras director. The indictment does not state that Pride or Ensco or any of their current or former employees were involved in the bribery scheme or had any knowledge of the bribery scheme.

On January 4, 2016, we received a notice from Petrobras declaring the DSA void effective immediately. Petrobras’ notice alleges that our former marketing consultant both received and procured the payment to employees of Petrobras of improper payments from SHI and that Pride had knowledge of this activity and assisted in the procurement of and/or facilitated these improper payments. We disagree with Petrobras’ allegations. See "—DSA Dispute" below for additional information.

Outside of Petrobras’ allegations, we have not been contacted by any Brazil governmental authority regarding alleged wrongdoing by Pride or Ensco or any of their current or former employees related to this matter. We cannot predict whether any U.S., Brazilian or other governmental authority will seek to investigate Pride's involvement in this matter, or if a proceeding were opened, the scope or ultimate outcome of any such investigation. If the SEC or DOJ determines that violations of the FCPA have occurred, or if any governmental authority determines that we have violated applicable anti-bribery laws, they could seek civil and criminal sanctions, including monetary penalties, against us, as well as changes to our business practices and compliance programs, any of which could have a material adverse effect on our business and financial condition. Our customers, business partners and other stakeholders could seek to take actions adverse to our interests. Further, investigating and resolving such allegations is expensive and could consume significant management time and attention. Although our internal investigation is substantially complete, we cannot predict whether any additional allegations will be made or whether any additional facts relevant to the investigation will be uncovered during the course of the investigation and what impact those allegations and additional facts will have on the timing or conclusions of the investigation. Our Audit Committee will examine any such additional allegations and additional facts and the circumstances surrounding them.

DSA Dispute

As described above, on January 4, 2016, Petrobras sent a notice to us declaring the DSA void effective immediately, reserving its rights and stating its intention to seek any restitution to which it may be entitled. We disagree with Petrobras’ declaration that the DSA is void. We believe that Petrobras has repudiated the DSA and have therefore accepted the DSA as terminated on April 8, 2016 (the "Termination Date"). At this time, we cannot reasonably determine the validity of Petrobras' claim or the range of our potential exposure, if any. As a result, there can be no assurance as to how this dispute will ultimately be resolved.

We did not recognize revenue for amounts owed to us under the DSA from the beginning of the fourth quarter of 2015 through the Termination Date as we concluded that collectability of these amounts was not reasonably assured. Additionally, our receivables from Petrobras related to the DSA from prior to the fourth quarter of 2015 are fully reserved on our condensed consolidated balance sheet as of March 31, 2016. We have initiated arbitration proceedings in the U.K. against Petrobras seeking payment of all amounts owed to us under the DSA, in addition to any other amounts to which we are entitled, and intend to vigorously pursue our claims. We have also initiated separate arbitration proceedings in the U.K. against SHI for any losses we have incurred in connection with the foregoing. There can be no assurance as to how these arbitration proceedings will ultimately be resolved.

Asbestos Litigation
    
We and certain subsidiaries have been named as defendants, along with numerous third-party companies as co-defendants, in multi-party lawsuits filed in Mississippi and Louisiana by approximately 47 plaintiffs. The lawsuits seek an unspecified amount of monetary damages on behalf of individuals alleging personal injury or death, primarily under the Jones Act, purportedly resulting from exposure to asbestos on drilling rigs and associated facilities during the 1960s through the 1980s.

During 2013, we reached an agreement in principle with 58 plaintiffs to settle lawsuits filed in Mississippi for a nominal amount. A special master reviewed all 58 cases and made an allocation of settlement funds among the parties. The District Court Judge reviewed the allocations and accepted the special master’s recommendations and approved the settlements. The settlement documents for most of the individual plaintiffs have been processed, and the cases have been dismissed. The settlement documents for approximately 13 individual plaintiffs are continuing to be processed.

We intend to vigorously defend against the remaining claims and have filed responsive pleadings preserving all defenses and challenges to jurisdiction and venue. However, discovery is still ongoing and, therefore, available information regarding the nature of all pending claims is limited. At present, we cannot reasonably determine how many of the claimants may have valid claims under the Jones Act or estimate a range of potential liability exposure, if any.

In addition to the pending cases in Mississippi and Louisiana, we have other asbestos or lung injury claims pending against us in litigation from time to time in other jurisdictions. Although we do not expect final disposition of these asbestos or lung injury lawsuits to have a material adverse effect upon our financial position, operating results or cash flows, there can be no assurances as to the ultimate outcome of the lawsuits.

   Other Matters

In addition to the foregoing, we are named defendants or parties in certain other lawsuits, claims or proceedings incidental to our business and are involved from time to time as parties to governmental investigations or proceedings, including matters related to taxation, arising in the ordinary course of business. Although the outcome of such lawsuits or other proceedings cannot be predicted with certainty and the amount of any liability that could arise with respect to such lawsuits or other proceedings cannot be predicted accurately, we do not expect these matters to have a material adverse effect on our financial position, operating results or cash flows.

In the ordinary course of business with customers and others, we have entered into letters of credit and surety bonds to guarantee our performance as it relates to our drilling contracts, contract bidding, customs duties, tax appeals and other obligations in various jurisdictions. Letters of credit and surety bonds outstanding as of March 31, 2016 totaled $62.5 million and were issued under facilities provided by various banks and other financial institutions. Obligations under these letters of credit and surety bonds are not normally called as we typically comply with the underlying performance requirement. As of March 31, 2016, we had not been required to make collateral deposits with respect to these agreements.

Concentration of Risk

We are exposed to credit risk related to our receivables from customers, our cash and cash equivalents, our short-term investments and our use of derivatives in connection with the management of foreign currency exchange rate risk. We mitigate our credit risk relating to receivables from customers, which consist primarily of major international, government-owned and independent oil and gas companies, by performing ongoing credit evaluations. We also maintain reserves for potential credit losses, which generally have been within management's expectations. We mitigate our credit risk relating to cash and cash equivalents by focusing on diversification and quality of instruments. Cash equivalents consist of a portfolio of high-grade instruments. Custody of cash and cash equivalents is maintained at several well-capitalized financial institutions, and we monitor the financial condition of those financial institutions.  

We mitigate our credit risk relating to derivative counterparties through a variety of techniques, including transacting with multiple, high-quality financial institutions, thereby limiting our exposure to individual counterparties and by entering into International Swaps and Derivatives Association, Inc. (“ISDA”) Master Agreements, which include provisions for a legally enforceable master netting agreement, with almost all of our derivative counterparties. The terms of the ISDA agreements may also include credit support requirements, cross default provisions, termination events or set-off provisions.  Legally enforceable master netting agreements reduce credit risk by providing protection in bankruptcy in certain circumstances and generally permitting the closeout and netting of transactions with the same counterparty upon the occurrence of certain events.  See "Note 3 - Derivative Instruments" for additional information on our derivatives.
