Overview
OVERVIEW
OVERVIEW
SemGroup Corporation is a Delaware corporation headquartered in Tulsa, Oklahoma. SemGroup Corporation is the successor entity of SemGroup, L.P., which was an Oklahoma limited partnership. The terms “we,” “our,” “us,” “SemGroup,” “the Company” and similar language used in these notes to the unaudited condensed consolidated financial statements refer to SemGroup Corporation, SemGroup, L.P., and their subsidiaries.
Basis of presentation
The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States and the rules and regulations of the Securities and Exchange Commission. These financial statements include all normal and recurring adjustments that, in the opinion of management, are necessary to present fairly the financial position of the Company and the results of its operations and its cash flows.
The accompanying condensed consolidated financial statements are unaudited. The condensed consolidated balance sheet at December 31, 2012 is derived from audited financial statements.
Our condensed consolidated financial statements include the accounts of our controlled subsidiaries. All significant transactions between our consolidated subsidiaries have been eliminated.
The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts and disclosures in the financial statements. Although management believes these estimates are reasonable, actual results could differ materially from these estimates. The results of operations for the three months ended March 31, 2013, are not necessarily indicative of the results to be expected for the full year ending December 31, 2013.
Pursuant to the rules and regulations of the Securities and Exchange Commission, the accompanying condensed consolidated financial statements do not include all of the information and notes normally included with financial statements prepared in accordance with accounting principles generally accepted in the United States. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 31, 2012, which are included in our Annual Report on Form 10-K for the year ended December 31, 2012, filed with the Securities and Exchange Commission.
Certain reclassifications have been made to conform previously reported balances to the current presentation, including the reclassification of prior periods to reflect the SemStream segment's Arizona operations as discontinued operations.
Our significant accounting policies are consistent with those described in our Annual Report on Form 10-K for the year ended December 31, 2012.
Recent accounting pronouncements
On January 31, 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") 2013-01, "Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities," which clarifies the scope of the offsetting disclosure requirements in ASU 2011-11, "Disclosures About Offsetting Assets and Liabilities." Under ASU 2013-01, the disclosure requirements apply to derivative instruments accounted for in accordance with Accounting Standards Codification ("ASC") 815, "Derivatives and Hedging," including bifurcated embedded derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending arrangements that are either offset on the balance sheet or subject to an enforceable master netting arrangement or similar agreement. ASU 2013-01 is effective for fiscal years beginning on or after January 1, 2013, and interim periods within those years. Retrospective application is required for all comparative periods presented. We adopted this guidance in the first quarter of 2013. The impact of adoption was not material.
On February 5, 2013, the FASB issued ASU 2013-02, "Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income." This ASU adds new disclosure requirements for items reclassified out of accumulated other comprehensive income ("AOCI"). The ASU is intended to help entities improve the transparency of changes in other comprehensive income ("OCI") and items reclassified out of AOCI in their financial statements. It does not amend any existing requirements for reporting net income or OCI in the financial statements. We adopted this guidance in the first quarter of 2013. The impact of adoption was not material.
On February 28, 2013, the FASB issued ASU 2013-04, "Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date (a consensus of the FASB Emerging Issues Task Force)." The ASU requires entities to “measure obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date, as the sum of the following:
The amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors; and
Any additional amount the reporting entity expects to pay on behalf of its co-obligors.”
Required disclosures include a description of the joint-and-several arrangement and the total outstanding amount of the obligation for all joint parties. The ASU permits entities to aggregate disclosures (as opposed to providing separate disclosures for each joint-and-several obligation). These disclosure requirements are incremental to the existing related-party disclosure requirements in ASC 850, "Related Party Disclosures." The ASU is effective for public entities for all prior periods in fiscal years beginning on or after December 15, 2013, and interim reporting periods within those years. The Company will adopt this guidance in the first quarter of 2014. The impact is not expected to be material.
On March 4, 2013, the FASB issued ASU 2013-05, "Parent's Accounting for the Cumulative Translation Adjustment Upon Derecognition of Certain Subsidiaries or Groups of Assets Within a Foreign Entity or of an Investment in a Foreign Entity - a consensus of the FASB Emerging Issues Task Force”, which indicates that the entire amount of a cumulative translation adjustment ("CTA") related to an entity's investment in a foreign entity should be released when there has been a:
Sale of a subsidiary or group of net assets within a foreign entity and the sale represents the substantially complete liquidation of the investment in the foreign entity;
Loss of a controlling financial interest in an investment in a foreign entity (i.e., the foreign entity is deconsolidated); or
Step acquisition for a foreign entity (i.e., when an entity has changed from applying the equity method for an investment in a foreign entity to consolidating the foreign entity).
The ASU does not change the requirement to release a pro rata portion of the CTA of the foreign entity into earnings for a partial sale of an equity method investment in a foreign entity. For public entities, this ASU is effective for fiscal years beginning on or after December 15, 2013, and interim periods within those years. The Company will adopt this guidance in the first quarter of 2014. The impact is not expected to be material.
Rose Rock Midstream, L.P.
ROSE ROCK MIDSTREAM, L.P.
ROSE ROCK MIDSTREAM, L.P.
We control the operations of our consolidated subsidiary, Rose Rock Midstream, L.P. ("Rose Rock") through our ownership of the general partner interest. As of March 31, 2013, we own the 2% general partner interest and 58.2% of the limited partner interest made up of 2.9 million common units, 8.4 million subordinated units and 1.25 million Class A units.
On January 11, 2013, we contributed a 33% interest in SemCrude Pipeline, L.L.C. to Rose Rock in exchange for (i) cash of approximately $189.5 million, (ii) the issuance of 1.5 million common units, (iii) the issuance of 1.25 million Class A units and (iv) an increase of the capital account of the general partner of Rose Rock and a related issuance of general partner interest, to allow the general partner of Rose Rock to maintain its two percent general partner interest. SemCrude Pipeline, L.L.C. owns a 51% membership interest in White Cliffs Pipeline, L.L.C. ("White Cliffs"), which owns a 527-mile pipeline that transports crude oil from Platteville, Colorado to Cushing, Oklahoma (the "White Cliffs Pipeline"), giving Rose Rock an indirect 17% interest in White Cliffs.
The Class A units are not entitled to receive any distribution of available cash (other than upon liquidation) prior to the first day of the month immediately following the first month for which the average daily throughput volumes on the White Cliffs Pipeline for such month are 125,000 barrels per day or greater. Upon such date, the Class A units will automatically convert into common units.
As this transaction was between parties under common control, Rose Rock recorded its interest in SemCrude Pipeline, L.L.C. at SemGroup's historical value and as such no gain on the sale was recognized by SemGroup. Proceeds in excess of the historical value were accounted for as an equity transaction between Rose Rock and SemGroup and resulted in a $90.5 million reduction to noncontrolling interests in consolidated subsidiaries and an offsetting increase to additional paid-in capital of $56.8 million (net of tax impact of $33.7 million). This non-cash entry represents the portion of the proceeds in excess of historical cost which were attributed to Rose Rock's third-party unitholders.
In connection with this transaction, Rose Rock issued and sold 2.0 million common units to third-party purchasers in a private placement for aggregate consideration of $59.3 million. In addition, Rose Rock exercised the accordion feature of its revolving credit facility and increased the total borrowing capacity under the credit facility from $150 million to $385 million and made a borrowing of $133.5 million under the credit facility. The proceeds from the private placement and the borrowing were used by Rose Rock to fund the cash consideration in the transaction with us and to pay certain related transaction costs and expenses. Subsequent to the transaction, SemGroup owns 58.2% of the limited partner interest and the 2% general partner interest in Rose Rock.
SemGroup incurred $1.4 million of expense associated with the transaction including amounts expensed by Rose Rock. Rose Rock incurred $3.5 million of expense, of which $1.4 million of equity issuance costs were offset against proceeds, $1.6 million were related to the borrowing and were deferred, and $0.5 million were expensed.
Outside ownership interests in Rose Rock are reflected in “noncontrolling interests in consolidated subsidiaries” on our condensed consolidated balance sheets at March 31, 2013 and December 31, 2012. The portion of Rose Rock’s net income attributable to outside owners is reflected within “net income attributable to noncontrolling interests” in our condensed consolidated statements of operations and comprehensive income for the three months ended March 31, 2013.
We receive distributions from Rose Rock on our common and subordinated units and our 2% general partner interest, which includes our incentive distribution rights. Rose Rock intends to pay a minimum quarterly distribution of $0.3625 per unit, to the extent it has sufficient available cash, as defined in Rose Rock’s partnership agreement. Rose Rock’s partnership agreement requires Rose Rock to distribute all of its available cash each quarter in the following manner:

White Cliffs
We account for our 51% ownership of White Cliffs under the equity method, as the other owners have substantive rights to participate in its management. Under the equity method, we do not report the individual assets and liabilities of White Cliffs on our condensed consolidated balance sheets. Instead, our ownership interest is reflected in one line as a noncurrent asset on our condensed consolidated balance sheets.
In August 2012, the owners of White Cliffs approved an expansion project to construct a 12" pipeline from Platteville, Colorado to Cushing, Oklahoma. The project is expected to cost approximately $300 million which will be funded by capital calls to owners. Our funding requirement will be 51% of the total cost. We have contributed approximately $25.1 million for project funding up through March 31, 2013, including $22.7 million for the three months ended March 31, 2013, and estimate our expected remaining contributions to be $96.6 million and $29.5 million for 2013 and 2014, respectively.

The equity in earnings of White Cliffs for the three months ended March 31, 2013 and March 31, 2012 reported in our condensed consolidated statement of operations and comprehensive income is less than 51% of the net income of White Cliffs for the same period. This is due to certain general and administrative expenses we incur in managing the operations of White Cliffs that the other owners are not obligated to share. Such expenses are recorded by White Cliffs, and are allocated to our ownership interest. White Cliffs recorded $0.3 million and $0.9 million of such general and administrative expense for the three months ended March 31, 2013 and March 31, 2012, respectively.
NGL Energy
We own 9,133,409 common units representing limited partner interests in NGL Energy Partners LP (NYSE: NGL) (“NGL Energy”), which represents approximately 17.2% of the total 53,121,177 limited partner units of NGL Energy outstanding at December 31, 2012, and a 6.42% interest in the general partner of NGL Energy.
At March 31, 2013, the fair market value of our 9,133,409 common unit investment in NGL Energy was $245.7 million, based on a March 28, 2013 closing price of $26.90 per common unit. This does not reflect our interest in the general partner of NGL Energy. The excess of the recorded amount of our investment over the book value of our share of the underlying net assets primarily represents equity method goodwill. The fair value of our limited partner investment in NGL Energy is categorized as a Level 1 measurement as it is based on quoted market prices.
Our policy is to record our equity in earnings of NGL Energy on a one-quarter lag, as we do not expect information on the earnings of NGL Energy to always be available in time to consistently record the earnings in the quarter in which they are generated. Accordingly, we have recorded equity in earnings of NGL Energy of $6.9 million and $0.9 million in our condensed consolidated statements of operations and comprehensive income for the three months ended March 31, 2013 and 2012, respectively, which relate to the earnings of NGL Energy for the three months ended December 31, 2012 and 2011, prorated for the period of time we held our ownership interest in NGL Energy. We received cash distributions of $4.3 million and $1.2 million for the three months ended March 31, 2013 and 2012, respectively, related to these earnings from NGL Energy.

Glass Mountain Pipeline LLC
In May 2012, we formed a joint venture, Glass Mountain Pipeline, LLC (“Glass Mountain” or "GMP"), to construct, maintain and operate a 210-mile crude oil pipeline system originating in Alva and Arnett, Oklahoma and terminating at Cushing, Oklahoma. Construction of the pipeline is expected to be completed by the end of 2013. Once the pipeline is in service, it will be operated by a subsidiary of Rose Rock. Our original ownership interest in GMP was 25%. In September 2012, we acquired an additional 25% ownership interest in GMP bringing our total ownership interest to 50% . We account for our investment in GMP using the equity method. As of March 31, 2013, we have invested $87.8 million in GMP including our capital contributions, amounts paid to acquire the additional ownership percentage, and capitalized interest. We invested $13.4 million in GMP for the three months ended March 31, 2013. We expect to make additional contributions of approximately $38.6 million for the remainder of 2013.

SEGMENTS
Our businesses are organized based on the nature and location of the services they provide. Certain summarized information related to our reportable segments is shown in the tables below. None of the operating segments have been aggregated, other than White Cliffs, which has been included within the Crude segment. Our investment in NGL Energy is included within the SemStream segment. Although “Corporate and Other” does not represent an operating segment, it is included in the tables below to reconcile segment information to that of the consolidated Company. Eliminations of transactions between segments are also included within “Corporate and Other” in the tables below.
The accounting policies of each segment are the same as the accounting policies of the consolidated Company. Transactions between segments are generally recorded based on prices negotiated between the segments. Certain general and administrative and interest expenses incurred at the corporate level are allocated to the segments, based on our allocation policies in effect at the time.

*Relates primarily to exchange traded futures. Gain and loss positions on multiple contracts are settled net on a daily basis with the exchange.
“Level 1” measurements use as inputs unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. These include commodity futures contracts that are traded on an exchange. These also include common stock warrants (Note 10) which are traded on the New York Stock Exchange.
“Level 2” measurements use as inputs market observable and corroborated prices for similar commodity derivative contracts. Assets and liabilities classified as Level 2 include over-the-counter (“OTC”) traded forward contracts and swaps.
“Level 3” measurements use as inputs information from a pricing service and internal valuation models incorporating observable and unobservable market data. These include commodity derivatives, such as forwards and swaps for which there is not a highly liquid market, and therefore are not included in Level 2.
Financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the measurement requires judgment, and may affect the valuation of assets and liabilities and their placement within the fair value levels. At March 31, 2013, all of our physical fixed price forward purchases and sales contracts were being accounted for as normal purchases and normal sales.
There were no financial assets or liabilities classified as Level 2 or Level 3 during the three months ended March 31, 2013 and March 31, 2012, as such no rollforward of activity has been presented.
Commodity derivative contracts
Our consolidated results of operations and cash flows are impacted by changes in market prices for petroleum products. This exposure to commodity price risk is managed, in part, by entering into various commodity derivatives.
We seek to manage the price risk associated with our marketing operations by limiting our net open positions through (i) the concurrent purchase and sale of like quantities of petroleum products to create back-to-back transactions that are intended to lock in positive margins based on the timing, location or quality of the petroleum products purchased and delivered or (ii) derivative contracts. Our storage and transportation assets can also be used to mitigate location and time basis risk. All marketing activities are subject to our Comprehensive Risk Management Policy, which establishes limits in order to manage risk and mitigate financial exposure.
Our commodity derivatives can be comprised of swaps, future contracts and forward contracts of crude oil and natural gas liquids. These are defined as follows:
Swaps – OTC transactions where a floating price, basis or index is exchanged for a fixed (or a different floating) price, basis or index at a preset schedule in the future, according to an agreed-upon formula.
Futures contracts – Exchange traded contracts to buy or sell a commodity. These contracts are standardized by the exchange in terms of quality, quantity, delivery period and location for each commodity.
Forward contracts – OTC contracts to buy or sell a commodity at an agreed upon future date. The buyer and seller agree on specific terms (price, quantity, delivery period and location) and conditions at the inception of the contract.
The following table sets forth the unaudited notional quantities for commodity derivative instruments entered into (in thousands of barrels):

We have posted margin deposits as collateral with brokers who have the right of set off associated with these funds. Margin deposits outstanding for the periods ended March 31, 2013 and December 31, 2012 were $1.1 million and $1.9 million, respectively. These margin deposits have not been offset against our net commodity derivative instrument (contract) positions. Had these margin deposits been netted against our net commodity derivative instrument (contract) positions for the periods ended March 31, 2013 and December 31, 2012, we would have had net asset positions of $0.5 million and $0.8 million, respectively.

Warrants
As described in Note 10, upon emergence from bankruptcy, we issued certain common stock warrants. These warrants are recorded at fair value in other noncurrent liabilities on the condensed consolidated balance sheets, with changes in the fair value recorded to other expense (income).
Income Taxes
INCOME TAXES
INCOME TAXES
Due to our emergence from bankruptcy and overall restructuring, we recorded a full valuation allowance on all U.S. federal and state deferred tax assets in all prior periods. Deferred tax assets are reduced by a valuation allowance when a determination is made that it is more likely than not that some, or all, of the deferred tax assets will not be realized based on the weight of all available evidence. Evidence which is objectively verifiable carries a higher weight in the analysis. The ultimate realization of deferred tax assets is dependent upon the existence of sufficient taxable income of the appropriate character within the carryback and carryforward period available under the tax law. Sources of taxable income include future reversals of existing taxable temporary differences, future earnings and available tax planning strategies.

For the three months ended March 31, 2013, we have recorded a discrete tax benefit of $50.9 million for the partial release of our valuation allowance. Gain recognition, for tax purposes, on the contribution of a 33% interest in SemCrude Pipeline, L.L.C. to Rose Rock, as disclosed in Note 2, had a material impact to the available positive and objectively verifiable evidence for the current quarter and, combined with other factors, results in the change in our assessment of recoverability of the deferred tax assets. Under ASC 740, "Income Taxes", such evidence was not considered in the valuation allowance at December 31, 2012, due to fundamentals of the transaction which remained subject to market influence until closed. We did not release the valuation allowance attributable to a small portion of our state net operating loss carryovers which have shorter carryover periods. We have not released the valuation allowance on the foreign tax credits due to the foreign tax credit limitation and the relative subjectivity of forecasts of the relational magnitude of U.S. and foreign taxable income in future periods as well as the shorter carryover period available for the credits.

We have determined that no accruals related to uncertainty in tax positions are required. All income tax years of the Company ending after the emergence from bankruptcy remain open for examination in all jurisdictions. In foreign jurisdictions, all tax years within the relevant statute of limitations for periods prior to the emergence from bankruptcy remain open for examination. Currently, there are no examinations in progress for our federal or state jurisdictions. Canada Revenue Agency has initiated an income tax audit of SemCAMS ULC for the tax year 2009, which remains in progress. We do not anticipate the SemCAMS ULC audit will have a significant impact on the results of operations or financial position. No other foreign jurisdictions are currently under audit.

The effective tax rate was 987% for the three months ended March 31, 2013, and (120)% for the three months ended March 31, 2012. Significant items that impacted the effective tax rate for each period, as compared to the U.S. federal statutory rate of 35%, include earnings in foreign jurisdictions taxed at lower rates, a noncontrolling interest in Rose Rock for which taxes are not provided, warrant expense which is not deductible for tax purposes, and the impact of the valuation allowance or release recorded against our deferred tax assets. Further, the foreign earnings are taxed in foreign jurisdictions as well as in the U.S., since they are disregarded entities for U.S. federal income tax purposes. Deferred tax liabilities, with the exception of those related to certain long-lived assets, have been considered as a source of future taxable income in establishing the amount of the valuation allowance. These combined factors, and the magnitude of permanent items impacting the tax rate relative to income from continuing operations before income taxes, result in rates that are not comparable between the periods.

SemGroup corporate credit agreement
Our revolving credit facility had a capacity of $300 million at March 31, 2013. This capacity may be used either for cash borrowings or letters of credit, although the maximum letter of credit capacity is $250 million. At March 31, 2013, we had outstanding cash borrowings of $23.5 million on this facility and outstanding letters of credit of $5.1 million
At March 31, 2013, $23.5 million of our outstanding cash borrowings incurred interest at the alternate base rate (“ABR”) of 4.75%, calculated as the prime rate of 3.25% plus a margin of 1.5%.
At March 31, 2013, the commitment rate in effect on letters of credit was 2.5%. In addition, a fronting fee of 0.25% is charged on outstanding letters of credit. A commitment fee of 0.5% is charged on any unused capacity on the revolving credit facility.
At March 31, 2013, $3.2 million in capitalized loan fees, net of accumulated amortization, was recorded in other noncurrent assets, which is being amortized over the life of the facility.
We recorded interest expense related to the SemGroup revolving credit facility of $1.2 million and $1.5 million for the three months ended March 31, 2013 and 2012, respectively, including amortization of debt issuance costs.
At March 31, 2013, we were in compliance with the terms of the credit agreement.
On April 22, 2013, the credit agreement was amended to (i) permit the increase of the facility by up to an additional $300 million subject to satisfaction of certain conditions, (ii) remove the restriction limiting unsecured senior or subordinated indebtedness to $200 million, while establishing certain requirements for obtaining unsecured senior or subordinated indebtedness of $200 million or more and (iii) establish less restrictive leverage covenants.
On May 3, 2013, we elected to increase the credit facility capacity by $200 million, for a total capacity of $500 million. The facility can be increased by an additional $100 million. In connection with the increase, we recorded $2.2 million of capitalized loan fees which will be amortized over the remaining life of the facility.
The credit agreement is guaranteed by all of our material domestic subsidiaries (except for SemCrude Pipeline. L.L.C. and Rose Rock Midstream. L.P. and its subsidiaries) and secured by a lien on substantially all of our property and assets, subject to customary exceptions.
Rose Rock credit facility
At March 31, 2013, there were $152.5 million revolving cash borrowings outstanding on this facility, of which $52.5 million incurred interest at the ABR plus an applicable margin, and $100 million incurred interest at the Eurodollar rate plus an applicable margin. The interest rate in effect at March 31, 2013 on $52.5 million of ABR borrowings was 5.0%. The interest rate in effect at March 31, 2013 on $100 million of Eurodollar rate borrowings was 3.04%.
We had $48.9 million in outstanding letters of credit, and the rate in effect was 2.75%. In addition, a fronting fee of 0.25% is charged on outstanding letters of credit. A commitment fee that ranges from 0.375% to 0.50%, depending on a leverage ratio specified in the credit agreement, is charged on any unused capacity of the revolving credit facility.
On January, 11, 2013, the credit facility capacity was increased to $385 million and Rose Rock borrowed $133.5 million in connection with the purchase of a 33% interest in SemCrude Pipeline, L.L.C. from SemGroup and to pay transaction related expenses. The facility can be increased by an additional $165 million. Approximately $1.6 million of related costs have been capitalized and will be amortized over the remaining life of the facility.
We had $6.1 million of Secured Bilateral Letters of Credit outstanding at March 31, 2013. The interest rate in effect was 1.75% on $1.1 million and 2.0% on $5.0 million. Secured Bilateral Letters of Credit are external to the facility and do not reduce revolver availability.
We recorded $2.0 million and $0.5 million of interest expense related to this facility during the three months ended March 31, 2013 and 2012, respectively, including amortization of debt issuance costs.
At March 31, 2013, $2.9 million in capitalized loan fees, net of accumulated amortization, was recorded in other noncurrent assets, which is being amortized over the life of the facility.
At March 31, 2013, we were in compliance with the terms of the credit agreement.
SemMexico facilities
On July 13, 2012, SemMexico entered into a credit agreement that allows SemMexico to borrow up to 56 million Mexican pesos (U.S. $4.5 million at the March 31, 2013 exchange rate) at any time during the term of the facility, which matures in July 2013. Borrowings are unsecured and bear interest at the bank prime rate in Mexico plus 1.7%. At March 31, 2013, there were borrowings of 56 million Mexican pesos (U.S. $4.5 million at the March 31, 2013 exchange rate) outstanding on this facility and the interest rate in effect was 6.03%.
On June 13, 2012, SemMexico entered into a credit agreement that allows SemMexico to borrow up to 44 million Mexican pesos (U.S. $3.6 million at the March 31, 2013 exchange rate) at any time during the term of the facility, which matures in June 2015. Borrowings are unsecured and bear interest at the bank prime rate in Mexico plus 2.0%. At March 31, 2013, there were no outstanding borrowings on this facility.
SemMexico also has outstanding letters of credit of 292.8 million Mexican pesos at March 31, 2013 (U.S. $23.7 million at the March 31, 2013 exchange rate). Fees are generally charged on outstanding letters of credit at a rate of 0.5%.
SemMexico recorded interest expense of $7.0 thousand and $0.1 million during the three months ended March 31, 2013 and 2012, respectively, related to these facilities.
At March 31, 2013, we were in compliance with the terms of these facilities.
Capitalized interest
During the three months ended March 31, 2013 and 2012, we capitalized interest from our credit facilities of $0.9 million and $0.1 million, respectively.
Fair value
We estimate that the fair value of our long-term debt was not materially different than the recorded values at March 31, 2013, and is categorized as a Level 3 measurement. It is our belief that neither the market interest rates nor our credit profile have changed significantly enough to have had a material impact on the fair value of our debt outstanding at March 31, 2013.

Bankruptcy matters
On July 22, 2008 (the “Petition Date”), SemGroup, L.P., SemCrude, and Eaglwing filed petitions for reorganization under Chapter 11 of the U.S. Bankruptcy Code. While in bankruptcy, SemGroup, L.P. filed a plan of reorganization with the court, which was confirmed on October 28, 2009 (the “Plan of Reorganization”). The Plan of Reorganization determined, among other things, how pre-Petition Date obligations would be settled, the equity structure of the reorganized company upon emergence, and the financing arrangements upon emergence. SemGroup Corporation, SemCrude, and Eaglwing emerged from bankruptcy protection on November 30, 2009 (the “Emergence Date”).
(a)
Confirmation order appeal
Luke Oil appeal. On October 21, 2009, Luke Oil Company, C&S Oil/Cross Properties, Inc., Wayne Thomas Oil and Gas and William R. Earnhardt Company (collectively, “Luke Oil”) filed an objection to the Plan of Reorganization “to the extent that the Plan of Reorganization may alter, impair, or otherwise adversely affect Luke Oil’s legal rights or other interests.” On October 28, 2009, the bankruptcy court overruled the Luke Oil objection and entered the confirmation order. On November 6, 2009, Luke Oil filed a Notice of Appeal. On December 23, 2009, Luke Oil’s appeal was docketed in the United States District Court for the District of Delaware. We filed a motion to dismiss the appeal as equitably moot. On May 21, 2012, the District Court entered an order granting our motion to dismiss Luke Oil's appeal of the confirmation order. On June 18, 2012, Luke Oil filed its Notice of Appeal, notifying the District Court and the parties to the lawsuit that it was appealing the decision of the District Court to the United States Court of Appeals for the Third Circuit. The appeal has been fully briefed. The Court of Appeals heard oral argument on January 22, 2013, and has not yet ruled. While we believe that this action is without merit and are vigorously defending this matter on appeal, an adverse ruling on this action could have a material adverse impact on us.
(b)
Investigations
Around the time of our predecessor's bankruptcy filings, several governmental agencies launched investigations regarding the circumstances of the filings. The mandate and scope of these investigations were very broad and the investigations are ongoing.
Bankruptcy examiner. On October 14, 2008, the bankruptcy court appointed an examiner to (i) investigate the circumstances surrounding our predecessor's trading strategy prior to bankruptcy filings; (ii) investigate the circumstances surrounding certain insider transactions and the formation of SemGroup Energy Partners L.P. (a former subsidiary); (iii) investigate the circumstances surrounding the potential improper use of borrowed funds and funds generated from operations and the liquidation of assets to satisfy margin calls related to our predecessor's trading strategy and that of certain entities owned or controlled by former officers and directors of the general partner of SemGroup, L.P.; (iv) determine whether any directors, officers or employees of the general partner of SemGroup, L.P. participated in fraud, dishonesty, incompetence, misconduct, mismanagement, or irregularity in the management of our affairs; and (v) determine whether the SemGroup debtor estates have causes of action against current or former officers, directors, or employees of the general partner of SemGroup, L.P. arising from such participation. The examiner’s report was filed with the bankruptcy court on April 15, 2009.
Certain current and prior employees of the general partner of SemGroup, L.P. are referenced in the examiner’s report and the report’s conclusions may suggest possible civil or criminal liability on their part. To the extent such claims exist, they are property of a litigation trust that was established for the benefit of pre-petition creditors pursuant to the Plan of Reorganization, and are not property of the reorganized SemGroup Corporation. This litigation trust is pursuing claims against certain former officers, at its own expense. We may incur expenses, which are not expected to be material, related to information and document requests of the litigation trust related to such claims. Any indemnification obligations to such officers by SemGroup, L.P. were discharged under the Plan of Reorganization.
CFTC. On June 19, 2008, we received a request for voluntary production from the Commodity Futures Trading Commission (“CFTC”). Subsequent to the bankruptcy filings, the CFTC sent other requests for voluntary production. The CFTC has also served subpoenas upon us requiring us to produce various documents and for the depositions of our representatives. We continue to comply with the CFTC’s requests. We are unaware of any currently pending formal charges against us by the CFTC.
DOJ. On July 15, 2008, we received a subpoena from the Department of Justice (“DOJ”) directing us to produce documents responsive to the subpoena. We contacted the DOJ regarding the subpoena and the DOJ verbally voluntarily stayed compliance with the subpoena. We have not produced any documents to the DOJ and, to our knowledge, the DOJ is not currently pursuing any such production. We are unaware of any currently pending formal charges against us by the DOJ.
(c)
Claims reconciliation process
A large number of parties have made claims against us for obligations alleged to have been incurred prior to our predecessor's bankruptcy filing. On September 15, 2010, the bankruptcy court entered an order estimating the contingent, unliquidated and disputed claims and authorizing distributions to holders of allowed claims. Pursuant to that order we have begun making distributions to the claimants. We continue to attempt to settle unresolved claims.
Pursuant to the Plan of Reorganization, we committed to settle authorized and allowed bankruptcy claims by paying a specified amount of cash, issuing a specified number of warrants, and issuing a specified number of shares of SemGroup Corporation common stock. We do not believe the resolution of the remaining outstanding claims will exceed the total amount of consideration established under the Plan of Reorganization for all claimants; instead, the resolution of the remaining claims in some cases will impact the relative share of the established pool of common stock and warrants that certain claimants receive.
However, under certain circumstances we could be required to pay additional funds to settle the specified group of claims to be settled with cash. Pursuant to the Plan of Reorganization, a specified amount of restricted cash was set aside at the Emergence Date, which we expect to be sufficient to settle this group of claims. Since the Emergence Date, we have made significant progress in resolving these claims, and we continue to believe that the cash set aside at the Emergence Date will be sufficient to settle these claims. However, we have not yet reached a resolution of all of these claims, and if the total settlement amount of all of these claims exceeds the specified amount, we will be required to pay additional funds to satisfy the total settlement amount for this specified group of claims. If this were to become probable of occurring, we would be required to record a liability and a corresponding expense.
Blueknight claim
Blueknight Energy Partners, L.P. (“Blueknight”), which was formerly a subsidiary of SemGroup, together with other entities related to Blueknight, entered into a Shared Services Agreement on April 7, 2009, with SemCrude, L.P. and SemManagement, L.L.C. (which are currently subsidiaries of SemGroup). The services provided by SemCrude to Blueknight under this agreement included the coordination of movement of crude oil belonging to Blueknight’s customers and the operation of Blueknight’s Oklahoma pipeline system and its Cushing, Oklahoma terminal. Under the subsequent amendments to the agreements beginning in May 2010, certain of these services were phased out, and Blueknight began to manage the movement of its crude oil and the operation of its Cushing terminal.
In a letter dated August 18, 2011, Blueknight claimed that SemCrude owes Blueknight approximately 141,000 barrels of crude oil. We responded to Blueknight’s letter denying their charges and requesting documentation from Blueknight of its claim. On February 14, 2012, after months of interaction between the parties through which we requested Blueknight to substantiate its claim, Blueknight filed suit against us in the District Court of Oklahoma County, Oklahoma. On May 1, 2012, the court approved our motion to transfer this case to Tulsa County, Oklahoma. On July 2, 2012, the Tulsa County District Court appointed a Special Master to conduct a review of whether Blueknight is missing 141,000 barrels of crude oil from operations occurring during the months of April through June, 2010. The Special Master will prepare an advisory report to the Court of her findings and conclusions. We believe this matter is without merit and will vigorously defend our position; however, we cannot predict the outcome.
Environmental
We may from time to time experience leaks of petroleum products from our facilities and, as a result of which, we may incur remediation obligations or property damage claims. In addition, we are subject to numerous environmental regulations. Failure to comply with these regulations could result in the assessment of fines or penalties by regulatory authorities.
The Kansas Department of Health and Environment (“the KDHE”) initiated discussions during our bankruptcy proceeding regarding six of our sites in Kansas (five owned by Crude and one owned by SemGas) that KDHE believes, based on their historical use, may have soil or groundwater contamination in excess of state standards. KDHE sought our agreement to undertake assessments of these sites to determine whether they are contaminated. We reached an agreement with KDHE on this matter and entered into a Consent Agreement and Final Order with KDHE to conduct environmental assessments on the sites and to pay KDHE’s costs associated with their oversight of this matter. We have conducted Phase II investigations at all sites and results indicate that four of the sites have limited amounts of soil contamination that will require remediation and ground water contamination that may require further delineation and/or ongoing monitoring. Work plans have been submitted to, and approved by, the KDHE. We do not anticipate any penalties or fines for these historical sites.
A water pipeline break occurred at a SemCAMS facility during August 2010. This resulted in a spill of material that was predominantly salt water containing a small amount of hydrocarbons. The incident was investigated by Environment Canada and Alberta Environment. On February 14, 2012, charges were filed against SemCAMS by the Federal Government of Canada (Department of Fisheries) and the Province of Alberta (Alberta Environment) in connection with this incident. We have reviewed disclosure received from the agencies and engaged our expert to assist us in formulating our response. Our expert's report has been completed and was delivered to the crown in April 2013. Although it is not possible to predict the outcome of these proceedings, we accrued a liability for estimated fines and environmental contributions of $0.4 million in December 2010, which we still carry on our books at March 31, 2013.
Other matters
We are party to various other claims, legal actions, and complaints arising in the ordinary course of business. In the opinion of our management, the ultimate resolution of these claims, legal actions and complaints, after consideration of amounts accrued, insurance coverage and other arrangements, will not have a material adverse effect on our consolidated financial position, results of operations or cash flows. However, the outcome of such matters is inherently uncertain, and estimates of our consolidated liabilities may change materially as circumstances develop.
Asset retirement obligations
We will be required to incur significant removal and restoration costs when we retire our natural gas gathering and processing facilities in Canada. We have recorded an asset retirement obligation liability of $40.5 million at March 31, 2013, which is included within other noncurrent liabilities on our condensed consolidated balance sheets. This amount was calculated using the $105.5 million cost we estimate we would incur to retire these facilities, discounted based on our risk-adjusted cost of borrowing and the estimated timing of remediation.
The calculation of the liability for an asset retirement obligation requires the use of significant estimates, including those related to the length of time before the assets will be retired, cost inflation over the assumed life of the assets, actual remediation activities to be required, and the rate at which such obligations should be discounted. Future changes in these estimates could result in material changes in the value of the recorded liability. In addition, future changes in laws or regulations could require us to record additional asset retirement obligations.
Our other segments may also be subject to removal and restoration costs upon retirement of their facilities. However, we are unable to predict when, or if, our pipelines, storage tanks and other facilities would become completely obsolete and require decommissioning. Accordingly, we have not recorded a liability or corresponding asset, as both the amount and timing of such potential future costs are indeterminable.
Purchase and sale commitments
We routinely enter into agreements to purchase and sell petroleum products at specified future dates. We account for derivatives at fair value with the exception of commitments which have been designated as normal purchases and sales for which we do not record assets or liabilities related to these agreements until the product is purchased or sold. At March 31, 2013, such commitments included the following (in thousands):

Certain of the commitments shown in the table above relate to agreements to purchase product from a counterparty and to sell a similar amount of product (in a different location) to the same counterparty. Many of the commitments shown in the table above are cancellable by either party, as long as notice is given within the time frame specified in the agreement (generally 30 to 120 days).
Our SemGas segment has a take or pay contractual obligation related to the fractionation of natural gas liquids. This obligation began in July 2011 and continues through June 2015. At March 31, 2013, approximately $26 thousand was due under the contract and the amount of future obligation is approximately $2.5 million. SemGas also enters into contracts under which we are responsible for marketing the majority of the gas and natural gas liquids produced by the counterparties to the agreements. The majority of SemGas’ revenues were generated from such contracts.
During the first quarter 2012, SemGas committed to purchasing equipment related to a 125 mmcf per day processing facility. At March 31, 2013, the future obligation associated with this purchase is $1.7 million.

* On January 13, 2013, we contributed a 33% interest in SemCrude Pipeline, L.L.C. to our consolidated subsidiary, Rose Rock. As this transaction was between entities under common control, the interest in SemCrude Pipeline, L.L.C. was recorded by Rose Rock based on SemGroup's book value. This amount represents the purchase price in excess of book value which was attributed to the noncontrolling interest owners of Rose Rock. The entry to additional paid-in capital has been recorded net of tax.

There were no significant items reclassified out of accumulated other comprehensive loss to net income for the three months ended March 31, 2013.
Common stock
Upon emergence from bankruptcy, we issued 40,882,496 shares of common stock. The Plan of Reorganization specified that we were to issue an additional 517,500 shares of common stock in settlement of pre-petition claims. As of March 31, 2013, we have issued 225,393 shares of this stock and will issue the remainder as the process of resolving the claims progresses. The owners’ equity balances on the condensed consolidated balance sheets include the shares that are required to be issued in settlement of pre-petition claims. The shares of common stock reflected on the condensed consolidated balance sheet at March 31, 2013 are summarized below:

(*) These shares include 84,348 shares which vested during the three months ended March 31, 2013. Of these vested shares, recipients sold back to the Company 8,591 shares to satisfy tax withholding obligations which are being recognized at cost as treasury stock on the condensed consolidated balance sheet.
In addition to the shares in the table above, there are shares of unvested restricted stock outstanding at March 31, 2013. The par value of these shares has not yet been reflected in common stock on the condensed consolidated balance sheet, as these shares have not yet vested. There are also shares of restricted stock that were returned to treasury upon forfeiture. The par value of these shares is not reflected in the condensed consolidated balance sheet, as no accounting recognition is given to forfeited shares.
The common stock includes Class A and Class B stock. Class A stock is eligible to be listed on an exchange, whereas Class B stock is not. Any share of Class B stock may be converted to Class A at the election of the holder. Both classes of stock have full voting rights. Both classes of stock have a par value of $0.01 per share. The total number of shares authorized for issuance is 90,000,000 shares of Class A stock and 10,000,000 shares of Class B stock.
Equity-based compensation
We have reserved common stock for issuance pursuant to director and employee compensation programs. At March 31, 2013, there were approximately 550,000 unvested shares that have been granted under these programs. The par value of these shares is not reflected in common stock on the condensed consolidated balance sheet, as these shares have not yet vested. Shares of restricted stock awards that were forfeited were returned to treasury. The par value of these shares is not reflected in the condensed consolidated balance sheet, as no accounting recognition is given to forfeited shares. For certain of the awards, the number of shares that will vest is contingent upon our achievement of certain specified targets. If we meet the specified maximum targets, approximately 141,000 additional shares could vest.
Warrants
Upon emergence from bankruptcy, we issued 1,634,210 warrants. The Plan of Reorganization specified that we were to issue an additional 544,737 warrants in settlement of the pre-petition claims. As of March 31, 2013, we have issued 237,242 of the warrants and will issue the remainder as the process of resolving the claims progresses. The warrants are traded on the New York Stock Exchange under the ticker symbol SEMGWS. We classify the warrant fair value as a Level 1 measurement. The warrants reflected on the condensed consolidated balance sheet at March 31, 2013 are summarized below:
Warrants issued on Emergence Date

(*) During the three months ended March 31, 2013, certain warrant holders exercised a total of 41 warrants resulting in the issuance of 35 Class A shares.
Each warrant entitles the holder to purchase one share of common stock for $25 at any time before the November 30, 2014 expiration date. Upon exercise, a holder may elect a cashless exercise, whereby the number of shares to be issued to the holder is reduced, in lieu of a cash payment. The closing price of our common stock was $51.72 per share on March 28, 2013. In the event of a change in control of the Company, the holders of the warrants would have the right to sell the warrants to us, and we would have the right to purchase the warrants from the holders. In either case, the price to be paid for the warrants would be calculated using a standard pricing model with inputs specified in the warrant agreement.
Dividend
On May 8, 2013, we declared a dividend of $0.19 per share payable on May 30, 2013 to shareholders of record on May 20, 2013.

During the three months ended March 31, 2013 and March 31, 2012, we recorded expenses of $25.8 million and $4.0 million, respectively, related to the change in fair value of the warrants. Because of this, the warrants would have been antidilutive and, therefore, were not included in the computation of diluted earnings per share.

Other supplemental disclosures
We recorded a $90.5 million reduction to noncontrolling interests in consolidated subsidiaries and an offsetting increase to additional paid-in capital of $56.8 million (net of tax impact of $33.7 million). This non-cash entry represents the portion of the proceeds in excess of historical cost which were attributed to Rose Rock's third-party unitholders related to Rose Rock's purchase of a 33% interest in SemCrude Pipeline, L.L.C. (Note 2).

We paid cash interest of $0.6 million and $1.7 million for the three months ended March 31, 2013 and 2012, respectively.

We paid cash for income taxes (net of refunds received) of $1.3 million and $5.4 million for the three months ended March 31, 2013 and 2012, respectively.

We incurred liabilities for construction work in process that had not been paid of $5.8 million and $2.9 million as of March 31, 2013 and 2012, respectively. Such amounts are not included in capital expenditures on the consolidated statements of cash flows.

200 miles of gathering pipeline;
Rose Valley I plant - A 200 mmcfd (million cubic feet per day) cryogenic processing plant, expected to be in operation in in the first quarter of 2014;
Rose Valley II plant - A 200 mmcfd cryogenic processing plant, expected to be in operation in in the first quarter of 2016;
Approximately 540,000 net acre dedication in the core of the Mississippi Lime play, supported by a recently announced joint venture between Chesapeake and Sinopec International Petroleum Exploration and Production Corporation; and
A 20-year, 100% fee based, gas gathering and processing agreement by Chesapeake.

Overview [Abstract]
 
Basis of presentation
Basis of presentationThe accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States and the rules and regulations of the Securities and Exchange Commission. These financial statements include all normal and recurring adjustments that, in the opinion of management, are necessary to present fairly the financial position of the Company and the results of its operations and its cash flows. The accompanying condensed consolidated financial statements are unaudited. The condensed consolidated balance sheet at December 31, 2012 is derived from audited financial statements.Our condensed consolidated financial statements include the accounts of our controlled subsidiaries. All significant transactions between our consolidated subsidiaries have been eliminated.The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts and disclosures in the financial statements. Although management believes these estimates are reasonable, actual results could differ materially from these estimates. The results of operations for the three months ended March 31, 2013, are not necessarily indicative of the results to be expected for the full year ending December 31, 2013.Pursuant to the rules and regulations of the Securities and Exchange Commission, the accompanying condensed consolidated financial statements do not include all of the information and notes normally included with financial statements prepared in accordance with accounting principles generally accepted in the United States. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 31, 2012, which are included in our Annual Report on Form 10-K for the year ended December 31, 2012, filed with the Securities and Exchange Commission.Certain reclassifications have been made to conform previously reported balances to the current presentation, including the reclassification of prior periods to reflect the SemStream segment's Arizona operations as discontinued operations. Our significant accounting policies are consistent with those described in our Annual Report on Form 10-K for the year ended December 31, 2012. 
Recent accounting pronouncements
Recent accounting pronouncements
On January 31, 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") 2013-01, "Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities," which clarifies the scope of the offsetting disclosure requirements in ASU 2011-11, "Disclosures About Offsetting Assets and Liabilities." Under ASU 2013-01, the disclosure requirements apply to derivative instruments accounted for in accordance with Accounting Standards Codification ("ASC") 815, "Derivatives and Hedging," including bifurcated embedded derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending arrangements that are either offset on the balance sheet or subject to an enforceable master netting arrangement or similar agreement. ASU 2013-01 is effective for fiscal years beginning on or after January 1, 2013, and interim periods within those years. Retrospective application is required for all comparative periods presented. We adopted this guidance in the first quarter of 2013. The impact of adoption was not material.
On February 5, 2013, the FASB issued ASU 2013-02, "Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income." This ASU adds new disclosure requirements for items reclassified out of accumulated other comprehensive income ("AOCI"). The ASU is intended to help entities improve the transparency of changes in other comprehensive income ("OCI") and items reclassified out of AOCI in their financial statements. It does not amend any existing requirements for reporting net income or OCI in the financial statements. We adopted this guidance in the first quarter of 2013. The impact of adoption was not material.
On February 28, 2013, the FASB issued ASU 2013-04, "Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date (a consensus of the FASB Emerging Issues Task Force)." The ASU requires entities to “measure obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date, as the sum of the following:
The amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors; and
Any additional amount the reporting entity expects to pay on behalf of its co-obligors.”
Required disclosures include a description of the joint-and-several arrangement and the total outstanding amount of the obligation for all joint parties. The ASU permits entities to aggregate disclosures (as opposed to providing separate disclosures for each joint-and-several obligation). These disclosure requirements are incremental to the existing related-party disclosure requirements in ASC 850, "Related Party Disclosures." The ASU is effective for public entities for all prior periods in fiscal years beginning on or after December 15, 2013, and interim reporting periods within those years. The Company will adopt this guidance in the first quarter of 2014. The impact is not expected to be material.
On March 4, 2013, the FASB issued ASU 2013-05, "Parent's Accounting for the Cumulative Translation Adjustment Upon Derecognition of Certain Subsidiaries or Groups of Assets Within a Foreign Entity or of an Investment in a Foreign Entity - a consensus of the FASB Emerging Issues Task Force”, which indicates that the entire amount of a cumulative translation adjustment ("CTA") related to an entity's investment in a foreign entity should be released when there has been a:
Sale of a subsidiary or group of net assets within a foreign entity and the sale represents the substantially complete liquidation of the investment in the foreign entity;
Loss of a controlling financial interest in an investment in a foreign entity (i.e., the foreign entity is deconsolidated); or
Step acquisition for a foreign entity (i.e., when an entity has changed from applying the equity method for an investment in a foreign entity to consolidating the foreign entity).
The ASU does not change the requirement to release a pro rata portion of the CTA of the foreign entity into earnings for a partial sale of an equity method investment in a foreign entity. For public entities, this ASU is effective for fiscal years beginning on or after December 15, 2013, and interim periods within those years. The Company will adopt this guidance in the first quarter of 2014. The impact is not expected to be material.
Financial Instruments Financial Instruments (Policies)
Fair Value of Financial Instruments, Policy [Policy Text Block]
“Level 1” measurements use as inputs unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. These include commodity futures contracts that are traded on an exchange. These also include common stock warrants (Note 10) which are traded on the New York Stock Exchange.
“Level 2” measurements use as inputs market observable and corroborated prices for similar commodity derivative contracts. Assets and liabilities classified as Level 2 include over-the-counter (“OTC”) traded forward contracts and swaps.
“Level 3” measurements use as inputs information from a pricing service and internal valuation models incorporating observable and unobservable market data. These include commodity derivatives, such as forwards and swaps for which there is not a highly liquid market, and therefore are not included in Level 2.
Financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the measurement requires judgment, and may affect the valuation of assets and liabilities and their placement within the fair value levels.

* On January 13, 2013, we contributed a 33% interest in SemCrude Pipeline, L.L.C. to our consolidated subsidiary, Rose Rock. As this transaction was between entities under common control, the interest in SemCrude Pipeline, L.L.C. was recorded by Rose Rock based on SemGroup's book value. This amount represents the purchase price in excess of book value which was attributed to the noncontrolling interest owners of Rose Rock.
