Cautionary Note Regarding Forward-Looking Statements

Certain matters contained in this Quarterly Report on Form 10-Q include "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). We make these forward-looking statements in reliance on the safe harbor protections provided under the Private Securities Litigation Reform Act of 1995.

All statements, other than statements of historical fact, included in this Form 10-Q regarding the prospects of our industry, our anticipated financial performance, the anticipated performance of NGL Energy Partners LP, management’s plans and objectives for future operations, business prospects, outcome of regulatory proceedings, market conditions and other matters, may constitute forward-looking statements. In addition, forward-looking statements generally can be identified by the use of forward-looking words such as "may," "will," "expect," "intend," "estimate," "foresee," "project," "anticipate," "believe," "plans," "forecasts," "continue" or "could" or the negative of these terms or variations of them or similar terms. Although we believe that the expectations reflected in these forward-looking statements are reasonable, we cannot assure you that these expectations will prove to be correct. These forward-looking statements are subject to certain known and unknown risks, and uncertainties, as well as assumptions that could cause actual results to differ materially from those reflected in these forward-looking statements. Factors that might cause actual results to differ include, but are not limited to, those discussed in Item 1A of our most recent Annual Report on Form 10-K, entitled "Risk Factors," risk factors discussed in other reports that we file with the Securities and Exchange Commission (the "SEC") and the following:


•	Our ability to generate sufficient cash flow from operations to enable us to pay our debt obligations and our dividends or to fund our other liquidity needs;


•	Our ability to comply with the covenants contained in our credit agreements and the indentures governing our senior notes, including requirements under our credit agreements to maintain certain financial ratios;


•	The effect of our debt level on our future financial and operating flexibility, including our ability to obtain additional capital on terms that are favorable to us;


•	The ability of our subsidiary, Rose Rock Midstream, L.P., to make minimum quarterly distributions to its unitholders, including us;


•	The operations of NGL Energy Partners LP, which we do not control;


•	Any sustained reduction in demand for, or supply of, the petroleum products we gather, transport, process and store;


•	Our ability to obtain new sources of supply of petroleum products;


•	Our failure to comply with new or existing environmental laws or regulations or cross border laws or regulations;


•	The possibility that the construction or acquisition of new assets may not result in the corresponding anticipated revenue increases;


•	Changes in currency exchange rates;


•	A cyber attack involving our information systems and related infrastructure, or that of our business associates;


•	The risks and uncertainties of doing business outside of the U.S., including political and economic instability and changes in local governmental laws, regulations and policies; and


•	The possibility that our hedging activities may result in losses or may have a negative impact on our financial results.

New factors that could cause actual results to differ materially from those described in forward-looking statements emerge from time to time, and it is not possible for us to predict all such factors, or the extent to which any such factor or combination of factors may cause actual results to differ from those contained in any forward-looking statement.

Readers are cautioned not to place undue reliance on any forward-looking statements contained in this Form 10-Q, which reflect management’s opinions only as of the date hereof. Except as required by law, we undertake no obligation to revise or publicly release the results of any revision to any forward-looking statements.

SEMGROUP CORPORATION

Notes to Unaudited Condensed Consolidated Financial Statements


1.	OVERVIEW

SemGroup Corporation is a Delaware corporation headquartered in Tulsa, Oklahoma. 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 and its subsidiaries.

Basis of presentation

The accompanying condensed consolidated balance sheet at December 31, 2014, which is derived from audited financial statements, and the unaudited condensed consolidated interim 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 ("SEC"). 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.

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 and six months ended June 30, 2015, are not necessarily indicative of the results to be expected for the full year ending December 31, 2015.

Pursuant to the rules and regulations of the SEC, 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. Certain reclassifications have been made to conform previously reported balances to the current presentation. 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, 2014, which are included in our Annual Report on Form 10-K for the year ended December 31, 2014, filed with the SEC.

Our significant accounting policies are consistent with those described in our Annual Report on Form 10-K for the year ended December 31, 2014.

Recent accounting pronouncements

In July 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2015-11, "Inventory (Topic 330): Simplifying the Measurement of Inventory," which requires that inventory within the scope of the guidance be measured at the lower of cost and net realizable value rather than the lower of cost or market. The standard will be effective for public business entities for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The new guidance shall be applied prospectively and early adoption is permitted. The Company will adopt this guidance in the first quarter of 2017. The impact is not expected to be material.

In April 2015, the FASB issued ASU 2015-03, “Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs,” which is designed to simplify presentation of debt issuance costs. The standard requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The standard will be effective for U.S. public companies for annual reporting periods beginning after December 15, 2015. Early adoption is permitted. The new guidance shall be applied on a retrospective basis for all periods presented. The Company will adopt this guidance in the first quarter of 2016. The impact is not expected to be material.

In February 2015, the FASB issued ASU 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis,” which adds requirements that limited partnerships must meet to qualify as voting interest entities and modifies the evaluation of whether limited partnerships are variable interest entities or voting interest entities. It also eliminates the presumption that a general partner should consolidate a limited partnership. This guidance is effective for public companies for fiscal years beginning after December 15, 2015. The Company will adopt this guidance in the first quarter of 2016. The impact is not expected to be material.

In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers," which supersedes nearly all existing revenue recognition guidance under accounting principles generally accepted in the United States ("U.S. GAAP"). The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred

SEMGROUP CORPORATION

Notes to Unaudited Condensed Consolidated Financial Statements


1.	OVERVIEW, Continued

to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP.

The standard permits using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). On July 9, 0215, the FASB approved a one-year deferral and the standard is now effective for annual periods beginning after December 15, 2017, and interim periods therein. We are currently evaluating the impact of our pending adoption of ASU 2014-09 on our consolidated financial statements and have not yet determined the method by which we will adopt the standard. We will adopt this guidance in the first quarter of 2018.

In April 2014, the FASB issued ASU 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity," which raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. For public entities, this ASU is effective for fiscal years beginning on or after December 15, 2014, and interim periods within those years. The Company adopted this guidance in the first quarter of 2015. The impact was not material.


2.	ROSE ROCK MIDSTREAM, L.P.

We control the operations of our consolidated subsidiary, Rose Rock Midstream, L.P. (NYSE: RRMS) ("Rose Rock"), through our ownership of the general partner interest. As of June 30, 2015, we own the 2% general partner interest and a 55.2% limited partner interest.

On January 1, 2015, certain operational targets were achieved by White Cliffs Pipeline, L.L.C. ("White Cliffs") and all 3,750,000 Class A units held by the Company were converted to common units on a one-for-one basis. The conversion did not impact the total number of Rose Rock's outstanding units representing limited partner interests.

On February 13, 2015, we contributed the Wattenberg Oil Trunkline ("WOT") and our 50% ownership interest in Glass Mountain Pipeline LLC ("Glass Mountain") to Rose Rock for (i) cash of approximately $251.2 million, (ii) the issuance of 1.75 million common units, and (iii) an increase of the capital account of the general partner and a related issuance of general partner interest, to allow the general partner to maintain its 2% general partner interest.

As the transaction was between entities under common control, Rose Rock recorded the acquired assets and liabilities based on SemGroup's historical cost. The purchase price in excess of historical cost was treated as an equity transaction with SemGroup, which reduced the partners' capital accounts of Rose Rock's general and limited partners on a pro-rata basis.

Additionally, the acquisition of WOT created a change in reporting entity which required Rose Rock's historical results to be recast as if WOT had been part of Rose Rock in prior periods. The historical summarized financial information of Rose Rock has been recast to reflect this change. The impact to prior periods was not significant. Prior period earnings of WOT have been allocated to the general partner. The acquisition of the equity method investment in Glass Mountain did not create a change in reporting entity. As such, prior periods have not been recast to include the historical results of Glass Mountain. There was no impact to SemGroup as these entities are all reported within the Crude segment.

On February 17, 2015, certain targets specified in Rose Rock’s partnership agreement were achieved and all 8,389,709 subordinated units held by the Company were converted to common units. The conversion did not impact the total number of Rose Rock’s outstanding units representing limited partner interests.

Cash distributions

We receive distributions from Rose Rock on our common units, our 2% general partner interest and 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.

The following table shows the cash distributions paid or declared during 2015 and 2014 (in thousands, except for per unit amounts):

White Cliffs

Certain unaudited summarized income statement information of White Cliffs for the three months and six months ended June 30, 2015 and 2014 is shown below (in thousands):



	Three Months Ended June 30,				Six Months Ended June 30,
	2015		2014		2015		2014
Revenue	$	48,509	$	34,533	$	103,123	$	67,807
Operating, general and administrative expenses	$	9,045	$	5,539	$	17,398	$	12,307
Depreciation and amortization expense	$	8,587	$	4,537	$	17,125	$	8,930
Net income	$	30,870	$	24,457	$	68,593	$	46,570

The equity in earnings of White Cliffs for the three months and six months ended June 30, 2015 and 2014 is less than 51% of the net income of White Cliffs for the same periods. 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 $0.4 million and $0.4 million of such general and administrative expense for the three months ended June 30, 2015 and 2014, respectively. White Cliffs recorded $0.7 million and $0.8 million of such general and administrative expense for the six months ended June 30, 2015 and 2014, respectively.

The members of White Cliffs are required to contribute capital to White Cliffs to fund various projects. For the six months ended June 30, 2015, we contributed $21.4 million to these projects, including $13.1 million of contributions for an expansion project adding approximately 65,000 barrels per day of capacity. Remaining contributions related to the expansion project will be paid in 2015 and are expected to total $23.6 million. The project is expected to be completed in late 2015.

NGL Energy Partners LP

At June 30, 2015, we owned 4,652,568 common units representing limited partner interests in NGL Energy Partners LP (NYSE: NGL) ("NGL Energy"), which represents approximately 4.5% of the total 103,794,870 limited partner units of NGL Energy outstanding at March 31, 2015, and an 11.78% interest in the general partner of NGL Energy.

At June 30, 2015, the fair market value of our 4,652,568 common unit investment in NGL Energy was $141.1 million, based on a June 30, 2015 closing price of $30.33 per common unit. This does not reflect our 11.78% interest in the general partner of NGL Energy. 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, the equity in earnings from NGL Energy, which is reflected in our condensed consolidated statements of operations and comprehensive income for the three months and six months ended June 30, 2015 and 2014, relates to the earnings of NGL Energy for the three months and six months ended March 31, 2015 and 2014, respectively.

In the first quarter of 2015, NGL announced several transactions in which they issued common units publicly and privately which diluted our limited partnership interest. As we record activity on a one-quarter lag, we recognized a non-cash gain of $5.9 million associated with these issuances in the second quarter of 2015.

During the six months ended June 30, 2015, we sold 1,999,533 of our NGL Energy common units for $56.3 million, net of related costs of $0.5 million. We recorded net gains related to these sales of $6.6 million and $14.5 million in "other expense (income)" in our condensed consolidated statement of operations and comprehensive income for the three months and six months ended June 30, 2015, respectively.

Certain unaudited summarized income statement information of NGL Energy for the three months and six months ended March 31, 2015 and 2014 is shown below (in thousands):

*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 are based on inputs consisting of 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.

"Level 2" measurements are based on inputs consisting of market observable and corroborated prices for similar derivative contracts. Assets and liabilities classified as Level 2 include over the counter ("OTC") traded physical fixed priced purchases and sales forward contracts.

"Level 3" measurements are based on inputs from a pricing service and/or 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 above.

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 June 30, 2015, 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 recorded at fair value which were classified as Level 2 or Level 3 during the three months and six months ended June 30, 2015 and 2014. As such, no rollforward of Level 3 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, futures contracts and forward contracts of crude oil, natural gas 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.

6.	FINANCIAL INSTRUMENTS, Continued

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 notional quantities for commodity derivative instruments entered into (in thousands of barrels):



	Three Months Ended June 30,		Six Months Ended June 30,
	2015	2014	2015	2014
Sales	7,721	1,135	13,452	1,950
Purchases	7,508	1,005	13,413	1,815

We have not designated any of our commodity derivative instruments as accounting hedges. We have recorded the fair value of our commodity derivative instruments on our condensed consolidated balance sheets in other current assets and other current liabilities in the following amounts (in thousands):



	June 30, 2015				December 31, 2014
	Assets		Liabilities		Assets		Liabilities
Commodity contracts	$	445	$	—	$	1,674	$	—

We have posted margin deposits as collateral with brokers who have the right of set off associated with these funds. Our margin deposit balances were $1.1 million and $0.8 million at June 30, 2015 and December 31, 2014, respectively. These margin account balances 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 as of June 30, 2015 and December 31, 2014, we would have had net asset positions of $1.5 million and $2.5 million, respectively.

Realized and unrealized gains (losses) from our commodity derivatives were recorded to product revenue in the following amounts (in thousands):



	Three Months Ended June 30,						Six Months Ended June 30,
	2015			2014			2015			2014
Commodity contracts	$	(2,202	)	$	(1,942	)	$	(2,268	)	$	(2,749	)

Concentrations of risk

During the three months ended June 30, 2015, two customers of our Crude segment accounted for more than 10% of our consolidated revenues at approximately 35%. No suppliers accounted for more than 10% of our costs of products sold.

During the six months ended June 30, 2015, two customers of our Crude segment accounted for more than 10% of our consolidated revenues at approximately 35%. We purchased approximately $98.5 million of product from two third-party suppliers of our Crude segment, which represented approximately 23% of our costs of products sold.

At June 30, 2015, one third-party customer of our Crude segment accounted for approximately 39% of our consolidated accounts receivable.


7.	INCOME TAXES

The effective tax rate was 34% and 35% for the three months ended June 30, 2015 and 2014, respectively and 36% and 58% for the six months ended June 30, 2015 and 2014, respectively. The rate for the six months ended June 30, 2014 is impacted by $3.1 million Canadian withholding tax paid on remittances to the U.S. 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 and a non-controlling interest in Rose Rock for which taxes are not provided. 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.

7.	INCOME TAXES, Continued

We have a valuation allowance on a small portion of our state net operating loss carryovers with shorter carryover periods and our foreign tax credit carryover. 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. 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.

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. No foreign jurisdictions are currently under audit.

SemGroup senior unsecured notes

For the three months ended June 30, 2015 and 2014, we incurred $5.8 million and $5.8 million, respectively, of interest expense related to $300 million of 7.50% senior unsecured notes due 2021 (the "Notes") including the amortization of debt issuance costs. For the six months ended June 30, 2015 and 2014, we incurred $11.7 million and $11.7 million, respectively of interest expense related to the Notes including amortization of debt issuance costs.

SemGroup corporate revolving credit facility

At June 30, 2015, we had no outstanding cash borrowings on our $500 million revolving credit facility.

At June 30, 2015, we had outstanding letters of credit under the facility of $4.5 million, for which the rate in effect was 2.0%.

Rose Rock senior unsecured notes due 2022

At June 30, 2015, Rose Rock had outstanding $400 million of 5.625% senior unsecured notes due 2022 (the "Rose Rock 2022 Notes"). For the three months and six months ended June 30, 2015, we incurred $5.9 million and $11.7 million, respectively, of interest expense related to the Rose Rock 2022 Notes including amortization of debt issuance costs.

Rose Rock senior unsecured notes due 2023

On May 14, 2015, Rose Rock and its wholly-owned subsidiary, Rose Rock Finance Corporation ("Finance Corp."), as co-issuer, sold $350 million of 5.625% senior unsecured notes due 2023 (the “Rose Rock 2023 Notes”) to certain initial purchasers for resale to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and to non-U.S. persons outside the United States pursuant to Regulation S of the Securities Act. The Rose Rock 2023 Notes are guaranteed by all of Rose Rock's existing subsidiaries other than Finance Corp. Such guarantees of the Rose Rock 2023 Notes are full and unconditional and constitute the joint and several obligations of the subsidiary guarantors.

The Rose Rock 2023 notes were sold at 98.345% of par, a discount of $5.8 million. The discount is reported as a reduction to the face value of the Rose Rock 2023 Notes on our condensed consolidated balance sheets and is being amortized over the life of the Rose Rock 2023 Notes using the interest method. At June 30, 2015, the unamortized discount was $5.7 million.

The net proceeds from the offering of $337.7 million, after the discount and $6.5 million of underwriters' fees and offering expenses, were used to repay amounts borrowed under Rose Rock's revolving credit facility and for general partnership purposes.

The Rose Rock 2023 Notes are governed by an indenture among Rose Rock, its subsidiary guarantors, Finance Corp. and Wilmington Trust, National Association, as trustee (the “Indenture”). The Indenture includes customary covenants, including limitations on Rose Rock's ability to incur additional indebtedness or issue certain preferred shares; pay dividends and make certain distributions, investments and other restricted payments; create certain liens; sell assets; enter into transactions with affiliates; merge, consolidate, sell or otherwise dispose of all or substantially all of its assets; and designate its subsidiaries as unrestricted subsidiaries under the Indenture.

The Indenture includes customary events of default. A default would permit the trustee or holders of at least 25% in aggregate principal amount of the Rose Rock 2023 Notes then outstanding to declare all amounts owing under the Rose Rock 2023 Notes to be due and payable.

The Rose Rock 2023 Notes are effectively subordinated in right of payment to any of Rose Rock's, and the subsidiary guarantors', existing and future secured indebtedness to the extent of the value of the collateral securing such indebtedness.

Rose Rock may issue additional notes under the Indenture from time to time, subject to the terms of the Indenture.

Except as described below, the Rose Rock 2023 Notes are not redeemable at Rose Rock's option prior to May 15, 2019. From and after May 15, 2019, Rose Rock may redeem the Rose Rock 2023 Notes, in whole or in part, at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest, if redeemed during the twelve-month period beginning on May 15 of each of the years indicated below:



Year		Percentage
2019		102.813%
2020		101.406%
2021 and thereafter		100.000%

Prior to May 15, 2018, Rose Rock may, at its option, on one or more occasions, redeem up to 35% of the sum of the original aggregate principal amount of the Rose Rock 2023 Notes at a redemption price equal to 105.625% of the aggregate principal amount thereof, plus accrued and unpaid interest, with the net cash proceeds of one or more equity offerings of Rose Rock, or the parent of Rose Rock to the extent such net proceeds are contributed to Rose Rock, subject to certain conditions.

8.	LONG-TERM DEBT, Continued

Prior to May 15, 2019, Rose Rock may also redeem all or part of the Rose Rock 2023 Notes at a price equal to the principal plus a premium equal to the greater of 1% of the principal or the excess of the present value of the May 15, 2019 redemption price from the table above plus all required interest payments due through May 15, 2019, computed using a discount rate based on a published United States Treasury Rate plus 50 basis points, over the principal value of such Rose Rock 2023 Note.

In the event of a change of control, Rose Rock is required to offer to repurchase the Rose Rock 2023 Notes at an amount equal to 101% of the principal plus accrued and unpaid interest.

The Rose Rock 2023 Notes are also subject to a Registration Rights Agreement which requires Rose Rock to file a registration statement with the SEC and to use commercially reasonable efforts to consummate such exchange offer within one year of the settlement date of the Rose Rock 2023 Notes so that holders of the Rose Rock 2023 Notes can exchange the Rose Rock 2023 Notes and related guarantees for registered notes (the "Exchange Notes") and guarantees that have substantially identical terms as the Rose Rock 2023 Notes and related guarantees. The guarantees of the Exchange Notes will be full and unconditional and will constitute the joint and several obligations of the subsidiary guarantors. Failure to meet the terms of the Registration Rights Agreement will require Rose Rock to pay incremental interest of 0.25% per annum, increased by an additional 0.25% per annum for each 90-day period for which registration default continues (up to a maximum of 1.0% per annum).

Interest on the Notes is payable in arrears on May 15th and November 15th to holders of record on May 1st and November 1st each year until maturity.

For the three months and six months ended June 30, 2015, we incurred $2.7 million of interest expense related to the Rose Rock 2023 Notes including amortization of debt issuance costs.

Rose Rock revolving credit facility

At June 30, 2015, Rose Rock had no outstanding cash borrowings under the $585 million Rose Rock revolving credit facility.

At June 30, 2015, Rose Rock had $24.6 million in outstanding letters of credit, and the rate in effect was 2.75%.

Rose Rock had $36.0 million of Secured Bilateral Letters of Credit outstanding at June 30, 2015. The interest rate in effect was 1.75%. Secured Bilateral Letters of Credit are external to the facility and do not reduce availability for borrowing on the revolving credit facility.

We incurred $2.0 million and $2.6 million of interest expense related to this facility during the three months ended June 30, 2015 and 2014, respectively, including letters of credit and amortization of debt issuance costs. We incurred $4.2 million and $4.9 million of interest expense related to this facility during the six months ended June 30, 2015 and 2014, respectively, including letters of credit and amortization of debt issuance costs.

SemMexico revolving credit facility

SemMexico had a 44 million Mexican pesos (U.S. $2.8 million at the June 30, 2015 exchange rate) revolving credit facility, which matured in May 2015. At the time of the maturity, there were no outstanding borrowings.

At June 30, 2015, SemMexico had no outstanding borrowings on its 56 million Mexican pesos (U.S. $3.6 million at the June 30, 2015 exchange rate) revolving credit facility, which matured in July 2015. Borrowings are unsecured and bear interest at the bank prime rate in Mexico plus 1.50%.

On May 22, 2015, SemMexico entered into a 100 million Mexican pesos (U.S. $6.4 million at the June 30, 2015 exchange rate) revolving credit facility, which matures in May 2018. There were no outstanding borrowings on the facility at June 30, 2015. Borrowings are unsecured and bear interest at the bank prime rate in Mexico plus 1.50%.

At June 30, 2015, SemMexico had an outstanding letter of credit of 292.8 million Mexican pesos (U.S. $18.7 million at the June 30, 2015 exchange rate). The interest rate in effect was 0.40%.

Capitalized interest

During the six months ended June 30, 2015 and 2014, we capitalized interest from our credit facilities of $0.9 million and $0.8 million, respectively.

Fair value

We estimate the fair value of the Notes, the Rose Rock 2022 Notes and the Rose Rock 2023 Notes to be $319 million, $392 million and $340 million, respectively, at June 30, 2015, based on unadjusted, transacted market prices, which are categorized as Level 1 measurements.


9.	COMMITMENTS AND CONTINGENCIES

Bankruptcy matters

On July 22, 2008 (the "Petition Date"), SemGroup, L.P. and certain subsidiaries filed petitions for reorganization under Chapter 11 of the U.S. Bankruptcy Code. Also on July 22, 2008, SemGroup, L.P.'s Canadian subsidiaries filed for creditor protection in Canada. Later during 2008, certain other U.S. subsidiaries filed petitions for reorganization. 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 emerged from bankruptcy protection on November 30, 2009 (the "Emergence Date").

Claims reconciliation process

A large number of parties made claims against us for obligations alleged to have been incurred prior to our predecessor's bankruptcy filing. We have resolved or settled all of these outstanding claims and have made all required distributions. The Plan of Reorganization has therefore been fully administered. On November 7, 2014, SemGroup Corporation and the other reorganized debtors moved for a final decree from the bankruptcy court closing the debtors’ bankruptcy cases. The United States Bankruptcy Court for the District of Delaware granted the request and entered its Order Granting Motion of Remaining Debtors for Entry of Final Decree on December 18, 2014. Accordingly, the bankruptcy cases for SemCrude, L.P., Eaglwing, L.P., SemCanada II, L.P., SemCanada L.P., SemGas, L.P., SemGroup, L.P., SemMaterials, L.P., and SemStream, L.P. have been closed. As part of its decree, the Court retained jurisdiction over certain on-going adversary proceedings, but the debtors have estimated and paid the claims associated with these remaining adversaries, leaving the non-debtor parties to the adversaries to resolve their remaining claims amongst themselves. On January 2, 2015, Bettina M. Whyte, the duly appointed Trustee of the SemGroup Litigation Trust (the “Litigation Trustee”), filed a notice of appeal of the Bankruptcy Court’s December 18, 2014 order closing the aforementioned bankruptcy cases. However, the Bankruptcy Court’s order of final decree was effective upon entry, and the appeal does not stay the effect of the order. The Litigation Trustee’s appeal to the United States District Court for the District of Delaware is currently pending and will be opposed by SemGroup Corporation and the other remaining reorganized debtors.

Dimmit County, TX claims

An employee of Rose Rock Midstream Field Services, LLC was involved in a tractor trailer accident on January 15, 2015 in Dimmit County, Texas. A second accident followed resulting in six fatalities and multiple injuries. At this time, the following lawsuits have been filed in either the District Court of Zavala County, Texas or the District Court of Dimmit County, Texas: Olga D. Rubio and Carlos Rubio, Individually and on Behalf of All Statutory Wrongful Death Beneficiaries of Carlos Rubio, Jr., Deceased vs. Rose Rock Midstream Field Services, LLC and Jesus T.

Midstream Field Services, LLC; Elizabeth Rolon vs. Rose Rock Midstream Field Services, LLC; Juan Francisco Medellin, III vs. Rose Rock Midstream Field Services, LLC and David Rodriguez and Maribel Rodriguez vs. Rose Rock Midstream Field Services, LLC and Jesus T. Riojas. We are currently working with counsel for the interested parties to investigate the accident, and no determination of liability has been made. We will continue to defend our position and believe that any liability that may arise from this incident will be covered by our insurance; however, we cannot predict the outcome.

Blueknight claim

Blueknight Energy Partners, L.P. ("Blueknight"), which was formerly a subsidiary of SemGroup, LP, together with other entities related to Blueknight, entered into a Shared Services Agreement on April 7, 2009, with SemCrude, L.P., now known as Rose Rock Midstream Crude, L.P. ("SemCrude") and SemManagement, L.L.C. (which are currently subsidiaries of SemGroup). The services provided by SemCrude to Blueknight under this agreement included from time to time certain operational tasks as requested by Blueknight in order that Blueknight could operate its Oklahoma pipeline system and its Cushing, Oklahoma terminal. Under the subsequent amendments to the agreement certain of these services were phased out, and Blueknight began to perform all services necessary for operation of its Cushing terminal without SemCrude’s assistance.

In a letter dated August 18, 2011, Blueknight claimed that SemCrude owes Blueknight approximately 141,000 barrels of crude oil, and that SemCrude came to possess this oil as a result of a breach of the agreement and other tortious conduct. We responded to Blueknight’s letter denying their charges and requesting documentation from Blueknight of its claim for missing barrels. On February 14, 2012, after months of interaction between the parties through which Blueknight was requested to substantiate its claim, Blueknight filed suit against SemCrude and other related companies in the District Court of Oklahoma County, Oklahoma. On May 1, 2012, the case was transferred to Tulsa County, Oklahoma. On July 2, 2012, the Tulsa County District Court appointed a Special Master to review terminal operations accounting records and determine whether 141,000 barrels of crude oil owned by Blueknight is missing after three months of operations in April through June, 2010. On June 11, 2013, the Special Master’s Report was filed with the District Court finding a shortage in Blueknight’s Cushing terminal and Oklahoma pipeline system of 148,000 barrels. However, after a review of all records created during that three month time period, the Special Master was unable to determine how the shortage might have occurred and was unable to determine the ownership of the potential shortage.

The parties completed discovery in the District Court, where substantial documentation was exchanged and deposition testimony was taken. All parties are seeking complete or partial summary adjudication on the various pending claims and counterclaims. These requests for summary adjudication are currently being briefed by the parties and have yet to be ruled upon by the Court. SemGroup will continue to defend its 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. Four of the sites have limited amounts of soil contamination that will be excavated and/or remediated on site. Four of the sites appeared to have ground water contamination requiring further delineation and/or ongoing monitoring. Work plans have been submitted to, and approved by, the KDHE. One site was closed and we anticipate closure in 2015 for one of the remaining five sites. Groundwater beneath two sites is being monitored until contaminants achieve regulatory threshold for closure and will not require active remediation. Two sites are in the process of completing assessment and characterization and will be remediated if necessary. We do not anticipate any penalties or fines for these historical sites.

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. During the second quarter of 2015, we completed a reevaluation of our asset retirement obligations and recorded reductions to the liability and offsetting asset of $26.0 million. The reduction was largely due to a change in the estimated timing of the retirement of the facilities. At June 30, 2015, we have an asset retirement obligation liability of $15.3 million, which is included within other noncurrent liabilities on our condensed consolidated balance sheets. This amount was calculated using the $116.2 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 June 30, 2015, such commitments included the following (in thousands):



	Volume (Barrels)	Value
Fixed price purchases	1,935	$	114,568
Fixed price sales	2,660	$	159,148
Floating price purchases	15,960	$	930,753
Floating price sales	22,129	$	1,129,425

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 through June 2023. At June 30, 2015, no amounts were due under the contract. The approximate amount of future obligation is as follows (in thousands):

There were no significant items reclassified out of accumulated other comprehensive loss to net income for the three months and six months ended June 30, 2015.

Common stock

During the six months ended June 30, 2015, we issued 9,145 shares under the Employee Stock Purchase Plan and 181,517 shares related to our equity based compensation awards. Of these vested shares related to compensation awards, recipients sold back to the Company 62,142 shares to satisfy tax withholding obligations which are being recognized at cost as treasury stock on the condensed consolidated balance sheet.

Equity-based compensation

At June 30, 2015, there were approximately 413,000 unvested shares that have been granted under our director and employee compensation 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. 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 171,000 additional shares could vest.

The holders of certain restricted stock awards granted in 2012 are entitled to equivalent dividends (“UDs”) to be received upon vesting of the related restricted stock awards. The dividends will be settled in common stock, based on the market price as of the close of business on the vesting date. In January 2015, 1,793 shares of common stock were issued upon the vesting of the 2012 restricted stock awards. Dividends related to the restricted stock awards granted subsequent to 2012 will be settled in cash upon vesting. At June 30, 2015, the value of the UDs related to cash settled unvested restricted stock awards was approximately $307 thousand.

During the six months ended June 30, 2015, we granted 151,588 restricted stock awards with a weighted average grant date fair value of $88.23 per award.

Dividends

The following table sets forth the quarterly dividends per share declared and/or paid to shareholders for the periods indicated:

11.	EARNINGS PER SHARE

Earnings per share is calculated based on income from continuing and discontinued operations less any income attributable to noncontrolling interests. Income attributable to noncontrolling interests represents third-party limited partner unitholders' interests in the earnings of our consolidated subsidiary, Rose Rock. Rose Rock allocates net income to its limited partners based on the distributions pertaining to the current period's available cash as defined by Rose Rock's partnership agreement. After adjusting for the appropriate period's distributions, the remaining undistributed earnings or excess distributions over earnings, if any, are allocated to Rose Rock's general partner, limited partners and participating securities in accordance with the contractual terms of Rose Rock's partnership agreement and as further prescribed under the two-class method. Incentive distribution rights do not participate in undistributed earnings.

Basic earnings per share is calculated based on the weighted average shares outstanding during the period. Diluted earnings per share includes the dilutive effect of warrants and unvested equity compensation awards.

The following summarizes the calculation of basic earnings per share for the three months and six months ended June 30, 2015 and 2014 (in thousands, except per share amounts):



	Three Months Ended June 30, 2015							Three Months Ended June 30, 2014

All outstanding warrants expired on November 30, 2014 and therefore have no dilutive effect for the three months and six months ended June 30, 2015. During the three months and six months ended June 30, 2014, we recorded expenses of $18.9 million and $17.9 million, respectively, related to the change in fair value of the warrants. Because the mark to market valuation of the warrants resulted in losses, the warrants would have been antidilutive and, therefore, were not included in the computation of diluted earnings per share.

Other supplemental disclosures

In the first quarter of 2015, we recorded a $51.5 million reduction to noncontrolling interests in consolidated subsidiaries and an offsetting increase to additional paid-in capital of $32.2 million (net of tax impact of $19.3 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 WOT and a 50% interest in Glass Mountain from SemGroup (Note 2).

In the second quarter of 2015, our SemCAMS segment completed the reevaluation of its asset retirement liability which resulted in reductions of $26.0 million to both the liability and offsetting asset. This non-cash adjustment is not reflected in our cash flows for the six months ended June 30, 2015.

In the second quarter of 2014, we recorded a $85.2 million reduction to noncontrolling interests in consolidated subsidiaries and an offsetting increase to additional paid-in capital of $53.4 million (net of tax impact of $31.8 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 the remaining 33% interest in SemCrude Pipeline, L.L.C. from SemGroup.

On June 27, 2014, Rose Rock agreed to sell $400 million of 5.625% senior unsecured notes due 2022. The net proceeds from the offering of $391.9 million, after underwriters' fees and offering expenses, were received on July 2, 2014 and were used to pay down Rose Rock's revolving credit facility balance. At June 30, 2014, we recorded a receivable for the proceeds and $8.7 million of debt issuance costs. These non-cash transactions have not been reflected in the cash flow statement for the six months ended June 30, 2014.

We paid cash interest of $28.2 million and $20.2 million for the six months ended June 30, 2015 and 2014, respectively.

We paid cash for income taxes (net of refunds received) of $5.7 million and $15.9 million for the six months ended June 30, 2015 and 2014, respectively.

We incurred liabilities for construction work in process that had not been paid of $16.8 million and $3.1 million as of June 30, 2015 and 2014, respectively. Such amounts are not included in capital expenditures on the consolidated statements of cash flows.

We received $0.2 million and $0.2 million in fees from Glass Mountain for the three months ended June 30, 2015 and 2014, respectively, related to support and administrative services associated with pipeline operations. We received $0.4 million and $0.4 million in fees from Glass Mountain for the six months ended June 30, 2015 and 2014, respectively, related to support and administrative services associated with pipeline operations. We made purchases of crude oil of $1.5 million from Glass Mountain during the six months ended June 30, 2015.

Legal services

The law firm of Conner & Winters, LLP, of which Mark D. Berman is a partner, performs legal services for us. Mr. Berman is the spouse of Candice L. Cheeseman, General Counsel and Secretary.

(collectively, the "Guarantors").

Each of the Guarantors is 100% owned by SemGroup Corporation (the "Parent"). Such guarantees of the Notes are full and unconditional and constitute the joint and several obligations of the Guarantors. There are no significant restrictions upon the ability of the Parent or any of the Guarantors to obtain funds from its respective subsidiaries by dividend or loan. None of the assets of the Guarantors represent restricted net assets pursuant to Rule 4-08(e)(3) of Regulation S-X under the Securities Act.

In February 2015, we contributed our interests in Wattenberg Holding, LLC and Glass Mountain Holding, LLC to Rose Rock (Note 2). As a result of this transaction, Wattenberg Holding, LLC and Glass Mountain Holding, LLC no longer guarantee our Notes. In June 2015, SemCanada, L.P. and SemCanada II, L.P. were released as Guarantors and no longer guarantee our Notes. Prior period comparative information has been recast to reflect Wattenberg Holding, LLC, Glass Mountain Holding, LLC, SemCanada, L.P. and SemCanada II, L.P. as non-guarantors.

Unaudited condensed consolidating financial statements for the Parent, the Guarantors and non-guarantors as of June 30, 2015 and December 31, 2014 and for the three months and six months ended June 30, 2015 and 2014 are presented on an equity method basis in the tables below (in thousands).

Intercompany receivable and payable balances, including notes receivable and payable, are capital transactions primarily to facilitate the capital needs of our subsidiaries. As such, subsidiary intercompany balances have been reported as a reduction to equity on the condensed consolidating Guarantor balance sheets. The Parent's net intercompany balance, including note receivable, and investments in subsidiaries have been reported in equity method investments on the condensed consolidating Guarantor balance sheets. Intercompany transactions, such as daily cash management activities, have been reported as financing activities within the condensed consolidating Guarantor statements of cash flows. The Parent's investing activities with subsidiaries, such as the drop down of WOT and Glass Mountain to Rose Rock in the first quarter of 2015, have been reflected as cash flows from investing activities. Quarterly cash distributions from Rose Rock representing a return on capital have been included in the Parent's cash flows from operations. These balances are eliminated through consolidating adjustments below.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the unaudited condensed consolidated interim financial statements and the notes thereto included in Part I, Item 1 of this Quarterly Report on Form 10-Q, and our Annual Report on Form 10-K for the year ended December 31, 2014, filed with the SEC.

Overview of Business

Our business is to provide gathering, transportation, storage, distribution, marketing and other midstream services primarily to independent producers, refiners of petroleum products and other market participants located in the Midwest and Rocky Mountain regions of the United States of America (the "U.S.") and Canada. We, or our significant equity method investees, have an asset base consisting of pipelines, gathering systems, storage facilities, terminals, processing plants and other distribution assets located between North American production and supply areas, including the Gulf Coast, Midwest, Rocky Mountain and Western Canadian regions. We also maintain and operate storage, terminal and marine facilities at Milford Haven in the United Kingdom (the "U.K.") that enable customers to supply petroleum products to markets in the Atlantic Basin. We also operate a network of liquid asphalt cement terminals throughout Mexico. Our operations are conducted directly and indirectly through our six primary business segments – Crude, SemStream^®, SemCAMS, SemLogistics, SemMexico and SemGas^®.

Our Assets

Our assets at June 30, 2015 included:

Non-GAAP Financial Measure

We define Adjusted gross margin as total revenues minus cost of products sold and unrealized gain (loss) on derivatives. Adjusted gross margin is not a financial measure presented in accordance with GAAP. We believe that the presentation of this non-GAAP financial measure provides useful information to investors in assessing our financial condition and results of operations. Operating income is the GAAP measure most directly comparable to Adjusted gross margin. Our non-GAAP financial measure should not be considered as an alternative to the most directly comparable GAAP financial measure. This non-GAAP financial measure has important limitations as an analytical tool because it excludes some, but not all, items that affect the most directly comparable GAAP financial measure. You should not consider Adjusted gross margin as a substitute for analysis of our results as reported under GAAP. Because Adjusted gross margin may be defined differently by other companies in our industry, our definition of this non-GAAP financial measure may not be comparable to similarly titled measures of other companies, thereby diminishing its utility.

Management compensates for the limitation of Adjusted gross margin as an analytical tool by reviewing the comparable GAAP measure, understanding the difference between Adjusted gross margin on the one hand, and operating income on the other hand, and incorporating this knowledge into its decision-making processes. We believe that investors benefit from having access to the same financial measure that our management uses in evaluating our operating results.

Revenue and Expenses

Revenue and expenses are analyzed by operating segment below.

General and administrative expense

General and administrative expenses of each corporate department are allocated to the segments based on criteria such as actual usage, headcount and estimates of effort or benefit. The method for allocating cost is based on the type of service being provided. For example, internal audit costs are based on an estimate of effort attributable to a segment. In contrast, accounting department costs are allocated based on the number of transactions processed for a given segment compared to the total number processed.

Interest expense

Interest expense increased in the three months ended June 30, 2015 to $16.8 million from $10.4 million in the three months ended June 30, 2014. Interest expense increased in the six months ended June 30, 2015 to $31.4 million from $19.6 million in the six months ended June 30, 2014. In both cases, the increase is primarily the result of $400 million of 5.625% senior unsecured notes issued on July 2, 2014 and the issuance of $350 million of 5.625% senior unsecured notes on May 14, 2015 by Rose Rock.

Table of Contents

Other expense (income), net

Other income was $6.7 million for the three months ended June 30, 2015, compared to other expense of $19.0 million for the same period in 2014. Other income was $14.7 million for the six months ended June 30, 2015, compared to other expense of $17.9 million for the same period in 2014. The increases are primarily due to net gains of $6.6 million and $14.5 million, respectively, on the sale of NGL Energy common units and the fact that losses related to outstanding warrants in 2014 did not reoccur in 2015 because the warrants expired on November 30, 2014.

Adjusted gross margin

We view Adjusted gross margin as an important performance measure of the core profitability of our operations, as well as our operating performance as compared to that of other companies in our industry, without regard to financing methods, historical costs basis, capital structure or the impact of fluctuating commodity prices. We define Adjusted gross margin as total revenues minus cost of products sold and unrealized gain (loss) on derivatives. Adjusted gross margin allows us to make a meaningful comparison of the operating results between our fee-based activities, which do not involve the purchase or sale of petroleum products, and our fixed-margin and marketing operations, which do. In addition, Adjusted gross margin allows us to make a meaningful comparison of the results of our fixed-margin and marketing operations across different commodity price environments because it measures the spread between the product sales price and costs of products sold.

Because Adjusted gross margin may be defined differently by other companies in our industry, our definition may not be comparable to similarly titled measures of other companies.

The following table presents a reconciliation of operating income to Adjusted gross margin, the most directly comparable GAAP financial measure for each of the periods indicated.

Adjusted gross margin increased in the three months ended June 30, 2015, to $48.8 million from $35.6 million in the three months ended June 30, 2014, due to:

•

an increase in marketing volume of approximately 5.5 million barrels in the three months ended June 30, 2015, over the same period in 2014, partially offset by a lower spread between the acquisition and sale price for volumes of crude oil sold, as the excess of our average sales price per barrel over our average acquisition cost per barrel decreased to approximately $1.65 for the three months ended June 30, 2015, from approximately $2.00 for the three months ended June 30, 2014. This resulted in a $7.8 million increase in Adjusted gross margin during the three months ended June 30, 2015, compared to the same period in 2014. The increase in volume was primarily due to crude oil blending and transactions related to contango market conditions;

Page 45

Table of Contents


•	additional truck transportation volumes of 3.3 million barrels generating an additional $2.6 million in Adjusted gross margin, reflecting the acquisition of trucking operations in June 2014. Related trucking costs are included in operating expense described below;


•	an increase in pipeline transportation and buy/sell volumes of approximately 2.3 million barrels, resulting in a $2.0 million increase in Adjusted gross margin during the three months ended June 30, 2015, compared to the same period in 2014;


•	an increase in pumpover activity at Cushing, resulting in a $0.6 million increase in Adjusted gross margin during the three months ended June 30, 2015, compared to the same period in 2014;


•	an increase in unloading volumes from our Platteville operations contributed an additional $0.2 million Adjusted gross margin, during the three months ended June 30, 2015, compared to the same period in 2014;


•	the additional 0.1 million barrels of storage capacity located at our Platteville, Colorado truck unloading facility contributed an additional $0.2 million Adjusted gross margin during the three months ended June 30, 2015 compared to the same period in 2014; and


•	although total Cushing storage capacity remained constant compared to the same period of the prior year, we reduced our leased storage capacity by 0.6 million barrels as we redeployed three tanks for our marketing activities. The reduction in leased storage resulted in a $0.2 million decrease to Adjusted gross margin during the three months ended June 30, 2015 compared to the same period in 2014.

Operating expense

Operating expense increased to $24.0 million in the three months ended June 30, 2015, from $17.7 million for the three months ended June 30, 2014. Approximately $6.1 million of the increase ($17.2 million compared to $11.1 million) is attributable to the crude oil trucking fleet. In addition, there were increases in field expense, employee expense, outside services and other expense of $0.3 million, $0.1 million, $0.1 million and $0.1 million, respectively. These increases were partially offset by a reduction in maintenance and repair expense of $0.4 million.

General and administrative

General and administrative expense remained relatively constant at $6.3 million in the three months ended June 30, 2015, compared to $6.4 million in the three months ended June 30, 2014.

Depreciation and amortization expense

Depreciation and amortization expense increased to $10.6 million in the three months ended June 30, 2015, from $7.3 million in the three months ended June 30, 2014. Approximately $1.9 million of the increase in depreciation expense is due to the 2014 revision of the estimated useful life relating to a section of the Kansas and Oklahoma pipeline system. An additional $2.0 million in depreciation expense is due to project completions and the acquisition of trucking operations in June 2014. Amortization expense related to contracts acquired as part of the crude oil trucking fleet acquisitions in 2013 and 2014 decreased by $0.6 million.

Earnings from equity method investments

Crude’s earnings from equity method investments increased in the three months ended June 30, 2015, to $17.7 million from $14.2 million in the three months ended June 30, 2014. This increase is primarily due to increased earnings from White Cliffs of approximately $3.3 million due to the commissioning of White Cliff's second line in August 2014. In addition, earnings from Glass Mountain increased by approximately $0.2 million.

Adjusted gross margin increased in the six months ended June 30, 2015, to $87.9 million from $74.1 million in the six months ended June 30, 2014, due to:

•

an increase in marketing volume of approximately 8.0 million barrels in the six months ended June 30, 2015, over the same period in 2014, partially offset by a lower spread between the acquisition and sale price for volumes of crude oil sold, as the excess of our average sales price per barrel over our average acquisition cost per barrel decreased to approximately $1.40 for the six months ended June 30, 2015, from approximately $1.95 for the six months ended June 30, 2014. This resulted in a $6.7 million increase in Adjusted gross margin during the six months ended June 30, 2015, compared to the same period in 2014. The increase in volume was primarily due to crude oil blending and transactions related to contango market conditions;

•	additional truck transportation volumes of 5.6 million barrels generating an additional $3.7 million in Adjusted gross margin, reflecting the acquisition of trucking operations in June 2014. Related trucking costs are included in operating expense described below;


•	an increase in pipeline transportation and buy/sell volumes of approximately 3.9 million barrels, resulting in a $3.0 million increase in Adjusted gross margin during the six months ended June 30, 2015, compared to the same period in 2014;


•	an increase in pumpover activity at Cushing, resulting in a $0.9 million increase in Adjusted gross margin during the six months ended June 30, 2015, compared to the same period in 2014;


•	an increase in unloading volumes from our Platteville operations contributed an additional $0.5 million Adjusted gross margin, during the three months ended June 30, 2015, compared to the same period in 2014;


•	the additional 0.1 million barrels of storage capacity located at our Platteville, Colorado truck unloading facility contributed an additional $0.2 million Adjusted gross margin during the six months ended June 30, 2015 compared to the same period in 2014; and

•

although total Cushing storage capacity remained constant compared to the same period of the prior year, we reduced our leased storage capacity by 0.6 million barrels as we redeployed three tanks for our marketing activities. The reduction in leased storage combined with a $0.01 decrease in the average lease rate per barrel, resulted in a $1.1 million decrease to Adjusted gross margin during the six months ended June 30, 2015 compared to the same period in 2014.

Operating expense

Operating expense increased to $45.1 million in the six months ended June 30, 2015, from $32.8 million for the six months ended June 30, 2014. Approximately $10.6 million of the increase ($32.1 million compared to $21.5 million) is attributable to the crude oil trucking fleet. In addition, there were increases in employee expense, outside services, office expense and other expense of $1.2 million, $0.5 million, $0.4 million and $0.1 million, respectively. These increases were partially offset by reductions in maintenance and repair and overhead expense allocation of $0.3 million and $0.2 million, respectively.

General and administrative

General and administrative expense increased to $12.0 million in the six months ended June 30, 2015, from $10.4 million in the six months ended June 30, 2014. This increase is due to additional overhead allocation, outside services and insurance and taxes of $1.0 million, $0.8 million and $0.5 million, respectively. These increases were partially offset by reductions in employee expense and other expense of $0.6 million and $0.1 million, respectively.

Depreciation and amortization expense

Depreciation and amortization expense increased to $20.8 million in the six months ended June 30, 2015, from $18.8 million in the six months ended June 30, 2014. A $0.5 million decrease in depreciation expense is due to the 2014 revisions of the estimated useful life relating to a section of the Kansas and Oklahoma pipeline system, offset by an additional $3.7 million in depreciation expense due to project completions and the acquisition of the crude oil trucking fleet. Amortization expense relating to contracts acquired as part of the crude oil trucking fleet acquisitions in 2013 and 2014 decreased by $1.2 million.

Earnings from equity method investments

Crude’s earnings from equity method investments increased in the six months ended June 30, 2015, to $38.5 million from $25.6 million in the six months ended June 30, 2014. This increase is primarily due to increased earnings of approximately $11.3 million from White Cliffs due to the commissioning of White Cliff's second line in August 2014. In addition, earnings from Glass Mountain increased by approximately $1.7 million.

SemStream

On November 1, 2011, we contributed the primary operating assets of our SemStream segment to NGL Energy in exchange for a limited partnership interest and a general partnership interest in NGL Energy and cash. The results of operations shown below reflect corporate overhead allocations, minor adjustments and the earnings from our equity method investment in NGL Energy. We include our share of NGL Energy's earnings on a one quarter lag because we do not receive their financial statements in sufficient time to apply the equity method to the current period. Our limited partnership interest can be diluted as a result of NGL Energy's public equity offerings. Accordingly, we recorded a non-cash gain of $5.9 million in the three months and six months ended June 30, 2015 and $8.1 million in the three months ended June 30, 2014.

For additional information about NGL Energy's results, see the NGL Energy periodic reports filed with the SEC.

Three months ended June 30, 2015 versus three months ended June 30, 2014

Crude oil prices fell sharply in the second half of 2014 and while prices have since increased, there is still some contango in the market (i.e., prices for future deliveries are higher than current prices), which has stimulated demand for storage. To meet this demand, we are refurbishing a number of tanks which are out of service and expect to have 1.2 million barrels of additional storage available by the fourth quarter of 2015. In addition, we believe that geographical imbalances between the production and consumption of crude oil and related refined products will require physical transportation and, as a result, bulk liquid storage will play a key role in the supply chain. This creates a demand for storage which is independent of current crude oil prices, forward price curves and the entire speculative trading environment.

Revenue

Revenue in the three months ended June 30, 2015 increased to $6.3 million from $4.0 million for the three months ended June 30, 2014. This increase is due primarily to increased storage volume, storage rates and throughput volume which contributed $1.5 million, $1.0 million and $0.7 million, respectively. These increases were offset, in part, by $0.7 million due to changes in foreign currency exchange rates.

Gain on disposal of long-lived assets, net

Gain on disposal of long-lived assets decreased $3.6 million in the three months ended June 30, 2015 compared to the three months ended June 30, 2014. In the three months ended June 30, 2014, a gain of $3.6 million was recorded as a result of the write off of intercompany indebtedness eliminated in consolidation. No similar write-off was recorded in the three months ended June 30, 2015.

General

In every other category of expense, the amounts for the second quarter of 2015 are roughly equivalent to those of the second quarter of 2014.

Six months ended June 30, 2015 versus six months ended June 30, 2014

Revenue

Revenue in the six months ended June 30, 2015 increased to $11.4 million from $8.8 million for the six months ended June 30, 2014. This increase is due to increased storage volume, storage rates and throughput volume which contributed incremental revenue of $2.1 million, $1.4 million and $0.9 million, respectively. These increases were offset, in part, by $1.2 million due to changes in foreign currency exchange rates. In addition, product sales of $0.7 million in 2014 did not reoccur in 2015.

General and administrative

General and administrative expense increased in the six months ended June 30, 2015 to $3.9 million from $3.0 million in the six months ended June 30, 2014. This increase is due primarily to an increase in employer compensation expense.

Depreciation and amortization

Depreciation and amortization expense decreased in the six months ended June 30, 2015 to $4.2 million from $5.1 million in the six months ended June 30, 2014. This decrease is due primarily to certain assets reaching the end of their depreciable lives in December 2014.

Gain on disposal of long-lived assets, net

Gain on disposal of long-lived assets decreased $3.6 million in the six months ended June 30, 2015 compared to the six months ended June 30, 2014. In the six months ended June 30, 2014, a gain of $3.6 million was recorded as a result of the write off of intercompany indebtedness eliminated in consolidation.

Three months ended June 30, 2015 versus three months ended June 30, 2014

Revenue

Revenue in the three months ended June 30, 2015 decreased to $35.9 million from $40.0 million for the three months ended June 30, 2014. This decrease is primarily due to lower operating costs recoveries and lower overhead recoveries of $1.4 million and $0.9 million, respectively. This decrease was offset, in part, by higher maintenance capital recovery of $1.8 million and $1.3 million from higher volumes processed. Foreign exchange changes reduced revenue by $4.6 million.

Operating Expense

Operating expense decreased in the three months ended June 30, 2015 to $23.7 million from $28.8 million for the three months ended June 30, 2014. This decrease is primarily due to foreign exchange gains of $3.0 million and lower costs for contract labor of $2.1 million.

Revenue

Revenue in the six months ended June 30, 2015 decreased to $65.6 million from $79.2 million for the six months ended June 30, 2014. This decrease is primarily due to lower operating cost recoveries and lower overhead recoveries of $6.0 million and $1.2 million, respectively. This decrease was offset, in part, by higher maintenance capital recovery of $1.4 million and $0.8 in higher fees. Foreign exchange changes reduced revenue by $8.2 million.

Operating Expense

Operating expense decreased in the six months ended June 30, 2015 to $42.0 million from $52.5 million for the six months ended June 30, 2014. This decrease is primarily due to lower costs for contract labor, materials and power of $2.7 million, $1.6 million and $1.2 million, respectively. Foreign exchange changes additionally reduced operating expense by $5.3 million.

Three months ended June 30, 2015 versus three months ended June 30, 2014

Revenue

Revenue decreased in the three months ended June 30, 2015 to $51.5 million from $63.0 million in the three months ended June 30, 2014. This decrease is primarily due to a decrease in the average sales price to $596 per metric ton in the three months ended June 30, 2015, from $717 per metric ton for the same period in 2014. This decrease is due to the change in the foreign currency exchange rates between periods. The average sales price in Mexican pesos did not change significantly between periods. In addition, the sales volume decreased to 85,037 metric tons in the three months ended June 30, 2015 from 86,515 metric tons in the same period in 2014.

Costs of products sold

Costs of products sold decreased in the three months ended June 30, 2015 to $41.2 million from $54.0 million in the three months ended June 30, 2014. In addition to the decrease in volumes sold, the costs of products sold on a per unit basis also decreased to $485 per metric ton in the three months ended June 30, 2015, from $624 per metric ton for the same period in 2014. This decrease results from the change in the foreign currency exchange rates between periods, as well as an 8% decrease in the cost of asphalt imported into Mexico from the U.S. (measured in Mexican pesos).

In every other category of expense, the amounts for the three months ended June 30, 2015 are roughly equivalent to those of the three months ended June 30, 2014.

Six months ended June 30, 2015 versus six months ended June 30, 2014

Revenue

Revenue decreased in the six months ended June 30, 2015 to $112.9 million from $134.6 million in the six months ended June 30, 2014. This decrease is primarily due to a decrease in the average sales price to $632 per metric ton for the six months ended June 30, 2015, from $702 per metric ton for the same period in 2014. This decrease is due primarily to the change in foreign currency exchange rates between periods. The average sales price increased 4% between periods in Mexican pesos. In addition, the sales volume decreased to 176,383 metric tons in the six months ended June 30, 2015 from 189,601 metric tons in the same period in 2014.

Costs of products sold

Costs of products sold decreased in the six months ended June 30, 2015 to $92.7 million from $115.5 million in the six months ended June 30, 2014. The decrease is due primarily to the change in foreign currency exchange rates between periods.

General and administrative

General and administrative expense decreased in the six months ended June 30, 2015 to $4.8 million from $5.9 million in the six months ended June 30, 2014. The decrease is primarily due to lower employee compensation expense and lower foreign currency exchange expense in the six months ended June 30, 2015 compared to the prior period.

Three months ended June 30, 2015 versus three months ended June 30, 2014

Revenue

Revenue decreased in the three months ended June 30, 2015 to $66.7 million from $93.0 million for the three months ended June 30, 2014. This decrease is the result of lower prices, offset by higher volume (37,305 MMcf versus 26,139 MMcf) and increased gathering and processing fees ($15.7 million versus $9.6 million). The decrease in revenue was affected by a lower average natural gas NYMEX price of $2.64/mmbtu versus $4.66/mmbtu and a lower average NGL basket price of $0.55/gallon versus $0.93/gallon for the same period in 2014. The increase in volume is primarily a result of increased drilling and production in the area served by our gas plants in Northern Oklahoma.

Costs of products sold

Costs of products sold decreased in the three months ended June 30, 2015 to $36.2 million from $68.2 million in the three months ended June 30, 2014. This decrease is primarily related to lower prices, offset by increased volumes as described above.

Operating expense

Operating expense increased in the three months ended June 30, 2015 to $8.8 million from $8.0 million for the three months ended June 30, 2014. This increase is due primarily to higher insurance, property and equipment, outside services and employment expenses of approximately $0.4 million, $0.3 million, $0.3 million and $0.1 million, respectively. These increases were offset by a decrease in field expenses and maintenance and repairs of $0.2 million and $0.1 million, respectively.

Depreciation and amortization

Depreciation and amortization expense increased in the three months ended June 30, 2015 to $7.4 million from $7.3 million in the three months ended June 30, 2014. The increase is primarily due to expansion in northern Oklahoma.

Loss on disposal of long-lived assets, net

Loss on disposal of long-lived assets, net decreased to $1.5 million in the three months ended June 30, 2015 from $20.1 million in the three months ended June 30, 2014. In June 2015, we wrote down certain gas gathering and compression assets in Kansas to their estimated net realizable value. On June 1, 2014, we sold certain natural gas gathering assets in Eastern Oklahoma for approximately $2.4 million, resulting in a loss of approximately $20.1 million. These assets were subject to contract renewal risk at the end of 2014 and were viewed as non-core due to their limited growth potential.

Six months ended June 30, 2015 versus six months ended June 30, 2014

Revenue

Revenue decreased in the six months ended June 30, 2015 to $133.0 million from $193.5 million for the six months ended June 30, 2014. This decrease is the result of lower prices, offset by higher volume (72,824 MMcf versus 44,034 MMcf) and increased gathering and processing fees ($30.2 million versus $10.8 million). The decrease in revenue was affected by a lower average natural gas NYMEX price of $2.81/mmbtu versus $4.80/mmbtu and a lower average NGL basket price of $0.56/gallon versus $0.98/gallon for the same period in 2014. The increase in volume is primarily a result of increased drilling and production in the area served by our gas plants in Northern Oklahoma, the start-up of the Rose Valley I processing plant in March 2014 and increased service contracts received in the Chesapeake acquisition.

General and administrative

General and administrative expense increased in the six months ended June 30, 2015 to $22.3 million from $9.6 million in the six months ended June 30, 2014. This increase is due primarily to business development expenses incurred during the first quarter of 2015.

Liquidity and Capital Resources

Sources and Uses of Cash

Our principal sources of short-term liquidity are cash generated from our operations and borrowings under our revolving credit facilities. The consolidated cash balance on June 30, 2015 (including restricted cash) was $228.8 million. Of this amount, $22.9 million was held in Canada and may be subject to tax if transferred to the U.S. Potential sources of long-term liquidity include issuances of debt securities and equity securities and the sale of assets. Our primary cash requirements currently are operating expenses, capital expenditures, our quarterly dividends and quarterly distributions to unitholders of our subsidiary, Rose Rock. In general, we expect to fund:


•	operating expenses, maintenance capital expenditures and cash dividends and distributions through existing cash and cash from operating activities;


•	expansion capital expenditures and any working capital deficits through cash on hand, borrowings under our credit facilities and the issuance of debt securities and equity securities;

Page 56

Table of Contents


•	acquisitions through cash on hand, borrowings under our credit facilities and the issuance of debt securities and equity securities; and


•	debt principal payments through cash from operating activities and refinancings when the credit facilities become due.

Our ability to meet our financing requirements and fund our planned capital expenditures will depend on our future operating performance and distributions from our equity investments, which will be affected by prevailing economic conditions in our industry. In addition, we are subject to conditions in the debt and equity markets for any issuances of debt securities and equity securities including common units in Rose Rock. There can be no assurance we will be able or willing to access the public or private markets in the future. If we would be unable or unwilling to access those markets, we could be required to restrict future expansion capital expenditures and potential future acquisitions.

We believe our cash from operations and our remaining borrowing capacity allow us to manage our day-to-day cash requirements, distribute our quarterly dividends, distribute the minimum quarterly distribution on Rose Rock's outstanding common units and meet our capital expenditures commitments for the coming year.

•	$17.9 million due to the prior year loss on the change in the fair value of warrants which expired in the fourth quarter of 2014;


•	$16.8 million due to lower losses on disposal or impairment of long-lived assets, net due to the write down of leaseholds related to unproved oil and gas properties in the prior year;


•	$14.5 million gain on the sale of a portion of our investment in an equity method investee, net of related costs;


•	$10.3 million increase in earnings from equity method investments which is primarily due to White Cliffs;

•	$11.4 million additional distributions from equity investments which is primarily due to White Cliffs;


•	$4.8 million increase in deferred tax expense;


•	$2.7 million additional depreciation and amortization expense;


•	$2.4 million increase in non-cash equity compensation;


•	$2.2 million increase due to a smaller current year gain, as compared to the prior year, related to issuances of common units by one of our equity method investees;


•	$1.7 million in excess tax benefits received from equity-based awards in the first quarter of 2014 that did not occur in 2015;


•	$1.5 million due to increased net unrealized losses related to our derivative instruments;


•	$1.2 million increase in inventory valuation adjustments due to write-downs of crude oil inventory as a result of lower market prices; and


•	All other adjustments to net income for non-cash expenses, net for the six months ended June 30, 2015 remained relatively comparable to the six months ended June 30, 2014.

Changes in operating assets and liabilities for the six months ended June 30, 2015 generated a net decrease to operating cash flows of $17.9 million. The decrease to operating cash flow due to the change in operating assets and liabilities was primarily a result of increases of $36.1 million in inventories, $3.1 million in other current assets, $2.1 million in other assets, $2.2 million in accounts receivable, $1.4 million in receivables from affiliates and a decrease of $3.8 million in payables to prepetition creditors. These were partially offset by increases of $18.7 million in accounts payable and accrued liabilities, $5.6 million in payables to affiliates and a decrease of $6.8 million in restricted cash. Changes in receivables, inventory, payables and accrued liabilities are primarily due to our Crude segment's operating activities and are subject to the timing of purchases and sales and fluctuations in commodity pricing. Additionally, the increase in inventory is due, in part, to approximately 700 thousand additional barrels in storage compared to the beginning of the period at our Crude segment. This is partially due to a strategic build to capture margins due to forward market crude oil prices being higher than spot market prices. Accounts receivable was also impacted by a $9.0 million decrease due to the collection of an accrued receivable at year-end which related to proceeds from the sale of a portion of our common limited partner units of NGL Energy.

Changes in operating assets and liabilities for the six months ended June 30, 2014 generated a net decrease in operating cash flows of $39.9 million, consisting primarily of a decrease of $39.6 million in payables to affiliates, a decrease of $14.2 million in accounts payable and accrued liabilities, an increase of $13.7 million in accounts receivable, an increase of $6.0 million in inventories, an increase of $2.6 million in other current assets and an increase of $2.2 million in restricted cash. These were offset by a decrease of $37.5 million in receivables from affiliates and an increase of $1.3 million in other noncurrent liabilities. These changes were primarily a result of our Crude and SemGas segments' operating activities.

Investing Activities

For the six months ended June 30, 2015, we had net cash outflows of $190.8 million from investing activities, due primarily to $237.0 million of capital expenditures, $23.5 million of contributions to equity method investments offset by investing cash inflows of $56.3 million of net proceeds from the sale of a portion of an equity method investment and $13.1 million of distributions in excess of equity in earnings of affiliates. Capital expenditures primarily related to Rose Rock's pipeline projects, SemGas' Northern Oklahoma expansion projects, the Maurepas Pipelines and SemCAMS' Wapiti expansion. Contributions to equity method investments primarily represent investments to fund the White Cliffs pipeline expansion project. Proceeds from the sale of equity method investment are due to the disposition of a portion of our common limited partner units of NGL Energy. Distributions in excess of equity in earnings of affiliates represent cash distributions from White Cliffs and Glass Mountain in excess of our cumulative equity in earnings and are accounted for as a return of investment.

For the six months ended June 30, 2014, we had net cash outflows of $230.7 million from investing activities, due primarily to $127.7 million of capital expenditures, $68.0 million of contributions to equity method investments and $44.5 million of payments to acquire businesses, partially offset by investing cash inflows of $5.4 million of distributions in excess of equity in earnings of affiliates and $4.0 million of proceeds from sale of long-lived assets. Year to date capital expenditures primarily relate to SemGas' North Oklahoma expansion projects, Rose Rock transportation projects and SemCAMS pipeline related projects. Investments in non-consolidated subsidiaries represents investments in Glass Mountain Pipeline and the White Cliffs pipeline expansion project. Payments to acquire businesses primarily relates to the $44 million acquisition of crude oil

trucking assets. Distributions in excess of equity earnings represent returns of investment from White Cliffs and Glass Mountain. Proceeds from sale of long-lived assets include $2.4 million from the sale of natural gas gathering assets in Eastern Oklahoma by SemGas.

Financing Activities

For the six months ended June 30, 2015, we had net cash inflows of $305.6 million from financing activities, which related to borrowings on long-term debt of $802.2 million, partially offset by principal payments of $525.0 million, $89.1 million in proceeds from the issuance of Rose Rock limited partner units, dividends paid of $31.5 million, distributions to non-controlling interests of $19.3 million, $6.3 million in debt issuance costs and $4.3 million to repurchase common stock for payment of statutory taxes due on equity-based compensation. Net borrowings were used primarily for capital expenditures and contributions to equity method investments.

For the six months ended June 30, 2014, we had net cash inflows of $170.3 million from financing activities, which related to borrowings on long-term debt of $533.8 million, partially offset by principal payments of $331.5 million, dividends paid of $19.6 million and distributions to non-controlling interests of $13.2 million. Net borrowings were used primarily for capital expenditures, contributions to equity method investments and acquisitions.

Shelf Registration Statements

We have access to a universal shelf registration statement which provides us with the ability to offer and sell an unlimited amount of debt and equity securities, subject to market conditions and our capital needs. This shelf registration statement expires in December 2015.

Rose Rock has an effective shelf registration statement with the SEC that, subject to market conditions and effectiveness at the time of use, allows Rose Rock to issue up to an aggregate of $500 million of debt or equity securities. In August 2013,

Page 59

Table of Contents

Rose Rock used this shelf registration statement to sell 4.75 million common units representing limited partner interests for proceeds of $152.5 million, net of underwriting discounts and commissions of $6.4 million. On February 13, 2015, Rose Rock issued and sold 2.3 million common units representing limited partner interests for net proceeds of $89.1 million under this shelf registration statement. Proceeds were used in connection with Rose Rock's acquisition of the Wattenberg Oil Trunkline and a 50% interest in Glass Mountain from SemGroup. This shelf registration statement expires in May 2016.

Rose Rock also has an effective shelf registration statement for the offer and sale, from time to time, of common units representing limited partner interests in Rose Rock having an aggregate offering price of up to $150 million. On May 12, 2015, Rose Rock entered into an Equity distribution Agreement under which Rose Rock is able to make such sales over a period of time and, from time to time, in transactions at prices which are market prices prevailing at the time of sale, prices related to market price or at negotiated prices. The counterparties to the Equity Distribution Agreement may act as sales agents for the common units or may purchase common units for their own accounts as principals. To date, no such sales have been made.

Capital Requirements

The midstream energy business can be capital intensive, requiring significant investment for the maintenance of existing assets or acquisition or development of new systems and facilities. We categorize our capital expenditures as either:


•	expansion capital expenditures, which are cash expenditures incurred for acquisitions or capital improvements that we expect will increase our operating income or operating capacity over the long-term; or


•	maintenance capital expenditures, which are cash expenditures (including expenditures for the addition or improvement to, or the replacement of, our capital assets or for the acquisition of existing, or the construction or development of new, capital assets) made to maintain our long-term operating income or operating capacity.

Projected capital expenditures for 2015 are estimated at $720 million in expansion projects, including capital contributions to affiliates for funding growth projects and acquisitions, and $55 million in maintenance projects. These estimates may change as future events unfold. See "Cautionary Note Regarding Forward-Looking Statements." During the six months ended June 30, 2015, we spent $237.0 million (cash basis) on capital projects and $23.5 million in capital contributions to affiliates for funding growth projects.

In addition to our budgeted capital program, we anticipate that we will continue to make significant expansion capital expenditures in the future. Consequently, our ability to develop and maintain sources of funds to meet our capital requirements is critical to our ability to meet our growth objectives. We expect that our future expansion capital expenditures will be funded by cash from operations, borrowings under our credit facilities and the issuance of debt and equity securities.

Credit Risk

We are subject to risks of loss resulting from nonpayment or nonperformance by our customers. We examine the creditworthiness of third-party customers to whom we extend credit and manage our exposure to credit risk through credit analysis, credit approval, credit limits and monitoring procedures, and for certain transactions, we may request letters of credit, prepayments or guarantees.

Customer Concentration

Shell Trading (US) Company and BP Oil Supply Co, customers of our Crude segment, accounted for more than 10% of our consolidated revenue for the three months ended June 30, 2015 at approximately 25% and 10%, respectively. Shell Trading (US) Company and BP Oil Supply Co, customers of our Crude segment, accounted for more than 10% of our consolidated revenue for the six months ended June 30, 2015 at approximately 24% and 11%, respectively. Although we have contracts with customers of varying durations, if one or more of our major customers were to default on their contract, or if we were unable to renew our contract with one or more of these customers on favorable terms, we might not be able to replace any of these customers in a timely fashion, on favorable terms or at all. In any of these situations, our revenues and our ability to pay cash dividends to our stockholders may be adversely affected. We expect our exposure to risk of non-payment or non-performance to continue as long as we remain substantially dependent on a relatively small number of customers for a substantial portion of our Adjusted gross margin.

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements as defined by Item 303 of Regulation S-K.

Commitments

There have been no material changes to our contractual obligations outside the ordinary course of our business from those previously disclosed in Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2014, although the value of product purchase commitments is less at June 30, 2015 than it was at December 31, 2014.

We routinely enter into agreements to purchase and sell petroleum products at specified future dates. We establish a margin for these purchases by entering into various types of physical and financial sale and exchange transactions through which we seek to maintain a position that is substantially balanced between purchases on the one hand and sales and future delivery obligations on the other. 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 June 30, 2015, such commitments included the following (volumes and dollars in thousands):



	Volume (Barrels)	Value
Fixed price purchases	1,935	$	114,568
Fixed price sales	2,660	$	159,148
Floating price purchases	15,960	$	930,753
Floating price sales	22,129	$	1,129,425

Our SemGas segment has a take or pay contractual obligation related to the fractionation of natural gas liquids. This obligation continues through June 2023. At June 30, 2015, no amounts were due under the contract and the amount of future obligation is approximately $72.7 million. SemGas further has a take or pay contractual obligation related to pipeline transportation. This obligation continues through October 2015. The amount of future obligation is approximately $1.5 million. In addition, our SemGas segment 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. During the three months and six months ended June 30, 2015, the majority of SemGas’ revenues were generated from such contracts.

In addition, we are committed to contributing $23.6 million to our equity method investee, White Cliffs, in 2015 for a capital expansion project.

Item 3.	Quantitative and Qualitative Disclosures about Market Risk

This discussion on market risks represents an estimate of possible changes in future earnings that would occur assuming hypothetical future movements in commodity prices, interest rates and currency exchange rates. Our views on market risk are not necessarily indicative of actual results that may occur, and do not represent the maximum possible gains and losses that may occur since actual gains and losses will differ from those estimated based on actual fluctuations in commodity prices, interest rates, currency exchange rates and the timing of transactions.

We are exposed to various market risks, including changes in (i) petroleum prices, particularly crude oil, natural gas and natural gas liquids, (ii) interest rates and (iii) currency exchange rates. We may use from time-to-time various derivative instruments to manage such exposure. Our risk management policies and procedures are designed to monitor physical and financial commodity positions and the resulting outright commodity price risk as well as basis risk resulting from differences in commodity grades, purchase and sales locations and purchase and sale timing. We have a risk management function that has responsibility and authority for our Comprehensive Risk Management Policy, which governs our enterprise-wide risks, including the market risks discussed in this item. Subject to our Comprehensive Risk Management Policy, our finance and treasury function has responsibility and authority for managing exposure to interest rates and currency exchange rates. To manage the risks discussed above, we engage in price risk management activities.

Revenue from our asset-based activities is dependent on throughput volume, tariff rates, the level of fees generated from our pipeline systems, capacity leased to third parties, capacity that we use for our own operational or marketing activities and

Page 63

Table of Contents

the level of other fees generated at our terminalling and storage facilities. Profit from our marketing activities is dependent on our ability to sell petroleum products at prices in excess of our aggregate cost. Margins may be affected during transitional periods between a backwardated market (when the prices for future deliveries are lower than the current prices) and a contango market (when the prices for future deliveries are higher than the current prices). Our petroleum product marketing activities within each of our segments are generally not directly affected by the absolute level of petroleum product prices, but are affected by overall levels of supply and demand for petroleum products and relative fluctuations in market-related indices at various locations.

However, the SemGas segment has exposure to commodity price risk because of the nature of certain contracts for which our fee is based on a percentage of proceeds or index related to the prices of natural gas, natural gas liquids and condensate. Given current volumes, liquid recoveries and contract terms, we estimate the following sensitivities over the next twelve months:


•	A 10% increase in the price of natural gas and natural gas liquids results in approximately a $4.2 million increase to Adjusted gross margin.


•	A 10% decrease in those prices would have the opposite effect.

This sensitivity may be impacted by changes in contract mix, change in production or other factors which are outside of our control.

Additionally, based on our open derivative contracts at June 30, 2015, an increase in the applicable market price or prices for each derivative contract would result in a decrease in the contribution from these derivatives to our crude oil sales revenues. A decrease in the applicable market price or prices for each derivative contract would result in an increase in the contribution from these derivatives to our crude oil sales revenues. However, the increases or decreases in crude oil sales revenues we recognize from our open derivative contracts are substantially offset by higher or lower crude oil sales revenues when the physical sale of the product occurs. These contracts may be for the purchase or sale of crude oil or in markets different from the physical markets in which we are attempting to hedge our exposure, or may have timing differences relative to the physical markets. As a result of these factors, our hedges may not eliminate all price risks.

The notional volumes and fair value of our commodity derivatives open positions as well as the change in fair value that would be expected from a 10% market price increase or decrease is shown in the table below (in thousands):



	Notional Volume (Barrels)	Fair Value	Effect of 10% Price Increase			Effect of 10% Price Decrease		Settlement Date
Crude oil:
Futures contracts	555	445	$	(3,301	)	$	3,301	June 2015

Margin deposits or other credit support, including letters of credit, are generally required on derivative instruments used to manage our price exposure. As commodity prices increase or decrease, the fair value of our derivative instruments changes, thereby increasing or decreasing our margin deposit or other credit support requirements. Although a component of our risk-management strategy is intended to manage the margin and other credit support requirements on our derivative instruments, volatile spot and forward commodity prices, or an expectation of increased commodity price volatility, could increase the cash needed to manage our commodity price exposure and thereby increase our liquidity requirements. This may limit amounts available to us through borrowing, decrease the volume of petroleum products we purchase and sell or limit our commodity price management activities.

Interest Rate Risk

We use variable rate debt and are exposed to market risk due to the floating interest rates on our credit facilities. Therefore, from time-to-time we may use interest rate derivatives to manage interest obligations on specific debt issuances. Our variable rate debt bears interest at LIBOR or prime, subject to certain floors, plus the applicable margin. At June 30, 2015, an increase in these base rates of 1%, above the base rate floors, would increase our interest expense by $0.4 million and $0.8 million for the three months and six months ended June 30, 2015, respectively.

The average interest rates presented below are based upon rates in effect at June 30, 2015 and December 31, 2014. The carrying value of the variable rate instruments in our credit facilities approximate fair value primarily because our rates fluctuate with prevailing market rates.

Page 64

Table of Contents

The following table summarizes our debt obligations:



Liabilities	June 30, 2015	December 31, 2014
Short-term debt - variable rate	$0.0 million	$0.0 million
Average interest rate	0.00%	0.00%
Long-term debt - variable rate	$0.0 million	$67.0 million
Average interest rate	0.00%	3.29%
Long-term debt - fixed rate	$300.0 million	$300.0 million
Fixed interest rate	7.50%	7.50%
Long-term debt - fixed rate	$750.0 million	$400.0 million
Fixed interest rate	5.625%	5.625%

Currency Exchange Risk

The cash flows relating to our U.K., Canada and Mexico operations are based on the U.S. dollar equivalent of such amounts measured in British pounds, Canadian dollars and Mexican pesos. Assets and liabilities of our U.K., Canadian and Mexican subsidiaries are translated to U.S. dollars using the applicable exchange rate as of the end of a reporting period. Revenue, expenses and cash flows are translated using the average exchange rate during the reporting period.

A 10% change in the average exchange rate during the three months and six months ended June 30, 2015 would change operating income by $1.7 million and $3.5 million, respectively.
