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, management’s plans and objectives for future operations, planned capital expenditures, 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 and documents 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 current and expected dividends or to fund our other liquidity needs;


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


•	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;


•	Our ability to access the debt and equity markets, which will depend on general market conditions and the credit ratings for our debt obligations and equity;


•	The failure to realize the anticipated benefits of our acquisition of 100% of the equity interests in Buffalo Parent Gulf Coast Terminals LLC ("Buffalo Parent"), the parent company of Buffalo Gulf Coast Terminals LLC ("BGCT") and HFOTCO LLC, doing business as Houston Fuel Oil Terminal Company LLC (“HFOTCO”);


•	The loss of, or a material nonpayment or nonperformance by, any of our key customers;


•	The amount of cash distributions, capital requirements and performance of our investments and joint ventures;


•	The consequences of any divestitures of non-strategic operating assets or divestitures of interests in some of our operating assets through partnerships and/or joint ventures;


•	The amount of collateral required to be posted from time to time in our purchase, sale or derivative transactions;


•	The impact of operational and developmental hazards and unforeseen interruptions;


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


•	Competition from other midstream energy companies;


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


•	Our ability to renew or replace expiring storage, transportation and related contracts;


•	The overall forward markets for crude oil, natural gas and natural gas liquids;


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


•	Any future impairment of goodwill resulting from the loss of customers or business;


•	Changes in currency exchange rates;


•	Weather and other natural phenomena, including climate conditions;


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

Page 3

Table of Contents


•	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;


•	Costs of, or changes in, laws and regulations and our failure to comply with new or existing laws or regulations, particularly with regard to taxes, safety and protection of the environment;


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


•	General economic, market and business conditions.

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.

_________________________________________________________________________________________________

Investors and others should note that we announce material company information using our investor relations website (www.semgroupcorp.com), SEC filings, press releases, public conference calls and webcasts. We use these channels, as well as social media, to communicate with our investors and the public about our company, our businesses and our results of operations. The information we post on social media could be deemed to be material information. Therefore, we encourage investors, the media and others interested in our company to review the information we post on the social media channels listed on our investor relations website.

As used in this Form 10-Q, and unless the context indicates otherwise, the terms “the Company,” “SemGroup,” “we,” “us,” “our,” “ours,” and similar terms refer to SemGroup Corporation, its consolidated subsidiaries, and its predecessors. We sometimes refer to crude oil, natural gas, natural gas liquids (natural gas liquids, or “NGLs,” include ethane, propane, normal butane, iso-butane, and natural gasoline), refined petroleum products, residual fuel oil and liquid asphalt cement, collectively, as “petroleum products” or “products.”

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, 2017, 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 (“U.S. GAAP”) 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 U.S. GAAP 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 nine months ended September 30, 2018, are not necessarily indicative of the results to be expected for the full year ending December 31, 2018.

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 U.S. GAAP. 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, 2017, which are included in our Annual Report on Form 10-K for the year ended December 31, 2017, 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, 2017.

Recently adopted accounting pronouncements

In May 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-09, “Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting”, to provide clarity and reduce diversity in practice in determining which changes to terms or conditions of a share-based payment award require an entity to apply modification accounting under Accounting Standards Codification Topic 718. We adopted this guidance in the first quarter of 2018. The impact was not material.

In March 2017, the FASB issued ASU 2017-07, “Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Post-retirement Benefit Cost”, which requires that an employer disaggregate the service cost component from other components of net benefit cost. This ASU also provides explicit guidance on how to present the service cost component and the other components of net benefit cost in the income statement and allows only the service cost component of net benefit cost to be eligible for capitalization. We adopted this guidance retrospectively in the first quarter of 2018. For the three months and nine months ended September 30, 2017, we reclassified $3.2 million and $3.3 million, respectively, of non-service pension costs from “general and administrative expense” to “other expense (income)”.

In October 2016, the FASB issued ASU 2016-16, “Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory”, which requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. We adopted this guidance in the first quarter of 2018. The impact was not material.

In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force)”, to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. The update addresses eight different transaction types and clarifies how to classify each in the statement of cash flows, where previously there was unclear or no specific guidance. We adopted this guidance in the first quarter of 2018. The impact was not material.

1.	OVERVIEW, Continued

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers”, as amended, which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred 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 were required under previous U.S. GAAP.

On January 1, 2018, we adopted the guidance of ASU 2014-09, codified as Accounting Standards Codification 606 - Revenue from Contracts with Customers (“ASC 606”), using a modified retrospective approach. Upon adoption, a reduction to accumulated deficit of $11.5 million was recorded to reflect the impact of adoption related to uncompleted contracts at the date of adoption. The impacts of adoption to the current period results are as follows (in thousands):

1.	OVERVIEW, Continued

•

Changes to revenue primarily relate to the timing of recognition of deficiencies on take-or-pay agreements for which there is a contractual make-up period and a change to reporting certain gas gathering and processing fees as revenue rather than a reduction of cost of sales. Under ASC 605 - Revenue (“ASC 605”), revenue related to deficiencies with a make-up period was deferred until the contractual right to make-up a deficiency expired. Under ASC 606, we recognize all or a portion of revenue related to deficiencies before the make-up period expires if we determine that it is probable that the customer will not make-up all or some of its deficient volumes, for example if there is insufficient capacity to make up the deficient volumes. This may lead to earlier recognition of deficiency revenues under ASC 606 as compared with ASC 605.


•	Changes to cost of sales are due to how certain gathering and processing fees related to percentage of proceeds contracts are treated as revenues rather than reductions to purchase price of commodities (cost of sales).

•

Changes to accounts receivable, net and noncurrent receivables (included in other noncurrent assets on the condensed consolidated balance sheets) primarily relate to the timing of recognizing take-or-pay deficiencies with make-up rights as discussed above. Noncurrent receivables related to contracts for which we do not have the right to bill the customer for deficiencies until the contract expiration date.


•	Changes to other noncurrent assets include success fee payments to third parties for certain contracts which were expensed as incurred under ASC 605, but which have been recognized as assets under ASC 606 and are amortized to general and administrative expense in the consolidated statement of operations and comprehensive income (loss).


•	Changes to deferred income taxes primarily relate to the deferred tax impact of adoption entries.


•	Changes to retained earnings are due to the impact of adoption at January 1, 2018, as described above, and cumulative differences in net income through September 30, 2018.

See Note 11 for additional information.

Recent accounting pronouncements not yet adopted

On August 27, 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement”, which modifies the disclosure requirements in Topic 820 by removing, adding or modifying certain fair value measurement disclosures. For public entities, this ASU is effective for annual periods beginning after December 15, 2019, and interim periods therein. Early adoption is permitted. We will adopt this guidance in the first quarter of 2020. The impact is not expected to be material.

In February 2018, the FASB issued ASU 2018-02, “Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income”, which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. For public entities, this ASU is effective for annual periods beginning after December 15, 2018, and interim periods within those years and early adoption is permitted in the year prior to the effective date. We will adopt this guidance in the first quarter of 2019. The amendments in this update should be applied either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recognized. The impact is not expected to be material.

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”, which introduces new guidance for estimating credit losses on certain types of financial instruments based on expected losses and the timing of the recognition of such losses. For public entities, this ASU is effective for annual periods beginning after December 15, 2019, and interim periods within those years and early adoption is permitted in the year prior to the effective date. We will adopt this guidance in the first quarter of 2020. The impact is not expected to be material.

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”, as amended, which amends the existing lease guidance to require lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by operating and finance leases and to disclose additional quantitative and qualitative information about leasing arrangements. This ASU, as amended, also provides clarifications surrounding the presentation of the effects of leases in the income statement and statement of cash flows. For public entities, this ASU will be effective for annual periods beginning after December 15, 2018, and interim periods within those years. We are currently evaluating the impact of the adoption of ASU 2016-02 on our consolidated financial statements, but are not yet able to quantify the impact. We

continue to monitor FASB activity related to this ASU and have engaged with various peer groups to assess certain interpretive issues related to this ASU. We expect to elect the package of practical expedients such that we will not reassess whether any expired or existing contracts contain leases, we will not reassess the lease classification for any expired or existing leases and we will not reassess initial direct costs for any leases. We will adopt the standard at January 1, 2019, and recognize a cumulative-effect adjustment to the opening balance of retained earnings as allowed by ASU 2018-11, “Leases (Topic 842): Targeted Improvements”.


2.	DISPOSALS OR IMPAIRMENTS OF LONG-LIVED ASSETS

On March 15, 2018, we completed the sale of our Mexican asphalt business for $70.7 million. We recorded a pre-tax gain on disposal of $1.6 million for the nine months ended September 30, 2018. The Mexican asphalt business was held for sale and carried at net realizable value at December 31, 2017. The Mexican asphalt business contributed $2.3 million of pre-tax income for the nine months ended September 30, 2018, excluding the gain on disposal.

On April 12, 2018, we completed the sale of our U.K. operations, SemLogistics, for $73.1 million in cash. We recorded a pre-tax gain on disposal of $0.4 million for the nine months ended September 30, 2018. The U.K. business was held for sale and carried at net realizable value at December 31, 2017. The U.K. business contributed pre-tax income of $5.4 million for the nine months ended September 30, 2018, excluding the gain on disposal.

For the nine months ended September 30, 2018, we recorded an incremental gain of $1.4 million related to customary post-closing adjustments related to the prior year sale of our equity interest in Glass Mountain Pipeline, LLC.

White Cliffs Pipeline, L.L.C.

We own a 51% interest in White Cliffs Pipeline, L.L.C. (“White Cliffs”), which we account for under the equity method. Certain unaudited summarized income statement information of White Cliffs for the three months and nine months ended September 30, 2018 and 2017, is shown below (in thousands):



	Three Months Ended September 30,						Nine Months Ended September 30,
	2018			2017			2018			2017
Revenue	$	43,855		$	45,445		$	128,455		$	145,288
Cost of products sold, exclusive of depreciation and amortization	$	(107	)	$	(360	)	$	(138	)	$	8,091
Operating, general and administrative expenses	$	5,514		$	5,723		$	17,511		$	17,849
Depreciation and amortization expense	$	9,624		$	9,154		$	28,821		$	27,619
Net income	$	28,825		$	30,928		$	82,262		$	91,688

Our equity in earnings of White Cliffs for the three months and nine months ended September 30, 2018 and 2017, 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.

The members of White Cliffs are required to contribute capital to White Cliffs to fund various projects. For the nine months ended September 30, 2018, we contributed $6.5 million for a project to convert one of White Cliff’s 12-inch pipelines from crude to natural gas liquids service. Remaining contributions related to the conversion project will be paid in 2018 and 2019 and are expected to total $27.2 million. The project is expected to be completed during the fourth quarter of 2019.

Glass Mountain Pipeline, LLC

On December 22, 2017, we completed the sale of our equity method investment in Glass Mountain Pipeline LLC (“Glass Mountain”) for $300 million, subject to working capital and other adjustments. Proceeds from the sale were used to repay borrowings on SemGroup’s revolving credit facility.

NGL Energy Partners LP

We own an 11.78% interest in the general partner of NGL Energy Partners LP (NYSE: NGL) (“NGL Energy”) which is being accounted for under the equity method in accordance with ASC 323-30-S99-1, as our ownership is in excess of the 3 to 5 percent interest which is generally considered to be more than minor. The general partner of NGL Energy is not a publicly traded company.

(1) Relates primarily to exchange traded futures. Gain and loss positions on multiple contracts are settled net on a daily basis with the exchange.

(2) Commodity derivatives are subject to netting arrangements.

“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 could 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 and interest rate swaps for which certain unobservable inputs are used in the valuation.

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 September 30, 2018, all of our physical fixed price forward purchases and sales commodity contracts were being accounted for as normal purchases and normal sales.

The following table summarizes changes in the fair value of our net financial liabilities classified as Level 3 in the fair value hierarchy (in thousands):

See Note 6 for fair value of debt instruments. The approximate fair value of cash and cash equivalents, accounts receivable and accounts payable is equal to book value due to the short-term nature of these items.

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 time and location basis risks, respectively. All marketing activities are subject to our Comprehensive Risk Management Policy, Delegation of Authority policy and their supporting policies and procedures, which establish 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.

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 derivative instruments entered into (in thousands of barrels):



	Three Months Ended September 30,		Nine Months Ended September 30,
	2018	2017	2018	2017
Sales	2,704	3,386	10,467	9,980
Purchases	2,701	2,820	9,892	9,772

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):



	September 30, 2018				December 31, 2017
	Assets		Liabilities		Assets		Liabilities
Commodity contracts	$	—	$	3,143	$	—	$	1,368

We have posted margin deposits as collateral with brokers who have the right of set off associated with these funds. At September 30, 2018 and December 31, 2017, our margin deposit balances were in net asset positions of $4.8 million and $1.9 million, 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 September 30, 2018 and December 31, 2017, we would have had asset positions of $1.7 million and $0.5 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 September 30,						Nine Months Ended September 30,
	2018			2017			2018			2017

Interest rate swaps

We have interest rate swaps which allow us to limit exposure to interest rate fluctuations. The swaps only apply to a portion of our outstanding debt and provide only partial mitigation of interest rate fluctuations. We have not designated the swaps as hedges, as such, changes in the fair value of the swaps are recorded through current period earnings as a component of interest expense. At September 30, 2018 and December 31, 2017, we had interest rate swaps with notional values of $524.3 million and $491.1 million, respectively. At September 30, 2018, the fair value of our interest rate swaps was $0.2 million which was reported within “other current assets” in our condensed consolidated balance sheet. At December 31, 2017, the fair value of our interest rate swaps was $1.2 million which was reported within “other current liabilities” in our condensed consolidated balance sheet. For the three months ended September 30, 2018 and 2017, we recognized realized and unrealized losses of $0.3 million and $0.6 million related to interest rate swaps, respectively. For the nine months ended September 30, 2018 and 2017, we recognized realized and unrealized gains of $1.5 million and $0.6 million related to interest rate swaps, respectively.

Foreign currency forwards

We have foreign currency forwards primarily to purchase Canadian dollars to limit exposure to foreign currency rate fluctuations for capital contributions to our SemCAMS segment primarily to fund capital projects. We have not designated the forwards as hedges; therefore, changes in the fair value of the forwards are recorded through current period earnings as a component of foreign currency transaction gains and losses. At September 30, 2018 and December 31, 2017, we had foreign currency forwards with notional values of $73.9 million and $197.7 million, respectively. At September 30, 2018, the fair value of our foreign currency forwards was $1.0 million, which is reported within "other current liabilities" in our condensed consolidated balance sheet. At December 31, 2017, the fair value of our foreign currency forwards was $2.6 million, which is reported within "other current assets" and “other noncurrent assets” in our condensed consolidated balance sheet. For the three months ended September 30, 2018, we recognized realized and unrealized gains of $1.0 million related to foreign currency forwards. For the nine months ended September 30, 2018, we recognized realized and unrealized losses of $5.5 million related to foreign currency forwards. For the three months and nine months ended September 30, 2017, there were no foreign currency forwards outstanding.

Concentrations of risk

During the three months ended September 30, 2018, two customers, primarily of our Crude Supply and Logistics segment, accounted for more than 10% of our consolidated revenue with revenues of $147.1 million. One third-party supplier primarily of our Crude Supply and Logistics segment accounted for more than 10% of our consolidated costs of products sold with purchases of $64.1 million.

During the nine months ended September 30, 2018, one customer, primarily of our Crude Supply and Logistics segment, accounted for more than 10% of our consolidated revenue with revenues of $492.5 million. One third-party supplier of our Crude Supply and Logistics segment accounted for more than 10% of our consolidated costs of products sold with purchases of $158.1 million.

At September 30, 2018, two third-party customers, primarily of our Crude Supply and Logistics segment, accounted for approximately 25% of our consolidated accounts receivable.

5. INCOME TAXES, Continued


5.	INCOME TAXES

The effective tax rate was (47)% and 66% for the three months ended September 30, 2018 and 2017, respectively. The effective tax rate was (159)% and 63% for the nine months ended September 30, 2018 and 2017, respectively. The rate for the nine months ended September 30, 2018 is impacted by a discrete tax expense related to the vesting of restricted stock in the amount of $1.7 million, a discrete tax expense of $10.0 million in Mexico on the sale of the 100% equity interest in our Mexican asphalt business, and a discrete tax expense of $2.7 million on the foreign tax deduction offset to branch deferreds on the sale of our U.K. operations. The rate is also affected by the U.S. deduction for foreign taxes. The rate for the nine months ended September 30, 2017, is impacted by a discrete tax expense related to the vesting of restricted stock in the amount of $1.4 million. Significant items that impacted the effective tax rate for each period, as compared to the U.S. federal statutory rate of 21%, include earnings in foreign jurisdictions taxed at different rates and foreign earnings taxed in foreign jurisdictions as well as in the U.S., since they are disregarded entities for U.S. federal income tax purposes. These combined factors, and the magnitude of the permanent items impacting the tax rate relative to income from continuing operations before income taxes, result in rates that are not comparable between the periods.

We have a valuation allowance on a small portion of our state net operating loss carryovers with shorter carryover periods and a foreign tax credit carryover generated in tax years prior to 2014. 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 analyzed filing positions in all of the federal, state and foreign jurisdictions where we are required to file income tax returns and 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 U.S. jurisdictions under general operation of the statute of limitations, including special provisions with regard to net operating loss carryovers. In foreign jurisdictions, all tax periods prior to the emergence from bankruptcy are closed. The statute of limitations has not been waived with respect to any foreign jurisdictions post emergence and tax periods are open for examination in accordance with the general statutes of each foreign jurisdiction. Currently, there are no examinations in progress for our federal and state jurisdictions. Canada Revenue Agency has completed an income tax audit of SemCAMS ULC for the tax years 2013 through 2015 with no material adjustments. No other foreign jurisdictions are currently under audit.

(2)	HFOTCO term loan B is due in quarterly installments of $1.5 million with a final payment due on June 26, 2025.

HFOTCO credit agreement

On June 26, 2018, HFOTCO and Buffalo Gulf Coast Terminals LLC ("BGCT") entered into an Amendment and Restatement Agreement (the “Amendment and Restatement Agreement”). Pursuant to the Amendment and Restatement Agreement, the HFOTCO credit agreement was amended and restated in its entirety (as so amended and restated, the “Restated HFOTCO Credit Agreement”).

The Restated HFOTCO Credit Agreement increases the aggregate term loans incurred thereunder to $600 million, terminates the HFOTCO $75.0 million revolving credit facility, and extends the maturity date of the term loans to June 26, 2025 (the “Maturity Date”). In addition, HFOTCO may incur additional term loans in an aggregate amount not to exceed the greater of $120 million and a measure of HFOTCO’s EBITDA, defined in the credit agreement, at the time of determination, plus additional amounts subject to satisfaction of certain leverage-based criteria, subject to receiving commitments for such additional term loans from either new lenders or increased commitments from existing lenders. The term loan B was issued at a discount of $1.5 million.

At HFOTCO’s option, the term loans will bear interest at the Eurodollar rate or an alternate base rate (“ABR”), plus, in each case, an applicable margin of 2.75% relating to any term loans accruing interest at the Eurodollar rate and 1.75% relating to term loans accruing interest at ABR.

The Restated HFOTCO Credit Agreement includes customary representations and warranties and affirmative and negative covenants, which were made only for the purposes of the Restated HFOTCO Credit Agreement and as of the specific date (or dates) set forth therein, and may be subject to certain limitations as agreed upon by the contracting parties, and apply only to BGCT, HFOTCO and any subsidiaries of HFOTCO party to the Restated HFOTCO Credit Agreement. Such limitations include the creation of new liens, indebtedness, making of certain restricted payments and payments on indebtedness, making certain dispositions, making material changes in business activities, making fundamental changes including liquidations, mergers or consolidations, making certain investments, entering into certain transactions with affiliates, making amendments to material agreements, modifying the fiscal year, dealing with hazardous materials in certain ways, entering into certain hedging arrangements, entering into certain restrictive agreements, and funding or engaging in sanctioned activities.

The Restated HFOTCO Credit Agreement includes customary events of default, including events of default relating to inaccuracy of representations and warranties in any material respect when made or when deemed made, non-payment of principal and other amounts owing under the Restated HFOTCO Credit Agreement, including, in respect of, violation of covenants, cross acceleration to any material indebtedness of BGCT, HFOTCO and its subsidiaries, bankruptcy and insolvency events, certain unsatisfied judgments, certain ERISA events, certain invalidities of loan documents and the occurrence of a change of control. A default under the Restated HFOTCO Credit Agreement would permit the participating banks to require immediate repayment of any outstanding loans with interest and any unpaid accrued fees, and subject to intercreditor arrangements with the holders of the HFOTCO tax exempt notes payable, exercise other rights and remedies.

HFOTCO acquisition final payment

On April 17, 2018, we made the final payment related to the HFOTCO acquisition in the amount of $579.6 million. The payment was funded through revolving credit facility borrowings and cash on hand.

Pledges and guarantees

Our senior unsecured notes are guaranteed by certain subsidiaries. See Note 16 for additional information.

Our $1.0 billion corporate revolving credit facility is guaranteed by all of SemGroup’s material wholly-owned domestic subsidiaries, with the exception of Maurepas Pipeline LLC and HFOTCO, and secured by a lien on substantially all of the property and assets of SemGroup Corporation and the other loan parties, subject to customary exceptions.

The HFOTCO term loan B and HFOTCO tax exempt notes payable are secured by substantially all of the assets of HFOTCO and its immediate parent, BGCT. The HFOTCO tax exempt notes payable have a priority position over the HFOTCO term loan B.

Letters of credit

We had the following outstanding letters of credit at September 30, 2018 (dollars in thousands):



SemGroup $1.0 billion revolving credit facility	2.75%	$	28,335
Secured bi-lateral⁽¹⁾	1.75%	$	47,501

(1) Secured bi-lateral letters of credit are external to the SemGroup $1.0 billion revolving credit facility and do not reduce availability for borrowing on the credit facility.

Capitalized interest

During the nine months ended September 30, 2018 and 2017, we capitalized interest of $9.6 million and $15.4 million, respectively.

Fair value

We estimate the fair value of our senior unsecured notes based on unadjusted, transacted market prices near the measurement date. Our other long-term debts are estimated to be carried at fair value as a result of the recent timing of borrowings or rate resets. We estimate the fair value of our consolidated long-term debt, including current maturities, to be approximately $2.6 billion at September 30, 2018, which is categorized as a Level 2 measurement.


7.	COMMITMENTS AND CONTINGENCIES

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 Transportation and one owned by SemGas) that KDHE believed, based on their historical use, may have had 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 sites are in various stages of follow-up investigation, remediation, monitoring, or closure under KDHE oversight. The environmental work at these sites is being completed under consent orders between Rose Rock Midstream Crude, L.P. and the KDHE. Two of the remaining sites have limited impacts to shallow soil and groundwater and the groundwater is currently being monitored on a semi-annual basis until such time that closure can be granted by the KDHE. No active remediation is anticipated for these two sites. The final two sites have required additional investigation and soil and groundwater remediation may be necessary to achieve KDHE closure. 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. At September 30, 2018, we have an asset retirement obligation liability of $21.2 million, which is included within other noncurrent liabilities on our condensed consolidated balance sheets. This amount was calculated using the $128.9 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 that 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 September 30, 2018, such commitments included the following (in thousands):



	Volume (Barrels)	Value
Fixed price purchases	1,469	$	102,956
Fixed price sales	1,469	$	102,801
Floating price purchases	8,506	$	632,046
Floating price sales	12,225	$	728,646

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. The approximate amount of future obligation is as follows (in thousands):

December 31, 2021	7,337
December 31, 2022	6,905
Thereafter	2,854
Total expected future payments	$	38,662

SemGas also enters into contracts under which we are responsible for marketing the majority of the gas and natural gas liquids produced by the counterparties to the agreements. The majority of SemGas’ revenues were generated from such contracts.

Our Crude Supply and Logistics segment has minimum volume commitments for pipeline transportation of crude oil. The approximate amount of future obligations is as follows (in thousands):



For year ending:
December 31, 2018	$	5,449
December 31, 2019	21,865

Thereafter	20,312
Total expected future payments	$	93,584


8.	EQUITY

Equity issuances

During the nine months ended September 30, 2018, 53,757 shares under the Employee Stock Purchase Plan were issued and 199,064 shares related to our equity-based compensation awards vested.

On October 22, 2018, Maurepas Pipeline, LLC, a subsidiary of SemGroup, sold Class B shares representing a 49% ownership interest to Alinda Capital Partners (“Alinda”) for $350 million, subject to customary post-closing adjustments. The Class B shares provide Alinda with a $2.2 million monthly preference on distributions. The Class B shares are convertible to Class A shares of Maurepas Pipeline, LLC at Alinda’s option anytime after the second anniversary of closing. SemGroup has a call option to repurchase Alinda’s shares prior to the fifth anniversary of closing for a fixed amount of $350 million plus 1% per annum, subject to a 24 month non-call period. The Class B shares provide Alinda with two out of five seats on the Board of Managers of Maurepas Pipeline, LLC and certain protective rights. The Class B shares will be reported as a noncontrolling interest in our consolidated financial statements.

Equity-based compensation

At September 30, 2018, there were 1,414,780 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 sheets, 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 570,000 additional shares could vest.

The holders of certain restricted stock awards are entitled to equivalent dividends (“UDs”) to be received upon vesting of the related restricted stock awards and will be settled in cash. At September 30, 2018, the value of the UDs to be settled in cash related to unvested restricted stock awards was approximately $2.4 million.

During the nine months ended September 30, 2018, we granted 687,470 restricted stock awards with a weighted average grant date fair value of $22.61 per award.

9.	REDEEMABLE PREFERRED STOCK

On January 19, 2018 (the “Issue Date”), we issued and sold to WP SemGroup Holdings L.P. (“Warburg”) and certain other investors an aggregate of 350,000 shares of Series A Cumulative Perpetual Convertible Preferred Stock, par value $0.01 per share, of the Company (the “Preferred Stock”), convertible into 10,606,061 shares (subject to adjustment) of the Company’s Class A Common Stock, par value $0.01 per share (the “Common Stock”), for a cash purchase price of $1,000 per share of Preferred Stock and aggregate gross proceeds to the Company of $350,000,000, which proceeds were utilized (i) to repay amounts borrowed under the Company’s revolving credit facility, (ii) to fund growth capital expenditures and (iii) for general corporate purposes. The Preferred Stock was recorded on our condensed consolidated balance sheets net of $7.7 million of issuance costs.

The Preferred Stock is a new class of equity security that ranks senior to the Common Stock with respect to distribution rights and rights upon liquidation. Subject to certain exceptions, so long as any Preferred Stock remains outstanding, no dividend or distribution will be declared or paid on, and no redemption or repurchase will be agreed to or consummated of, stock on a parity with the Preferred Stock (“Parity Stock”), Common Stock or any other shares of stock junior to the Preferred Stock, unless all accumulated and unpaid dividends for all preceding full fiscal quarters have been declared and paid with respect to the Preferred Stock. In addition, no dividend or distribution or redemption or repurchase shall be paid on Parity Stock, Common Stock or any other shares of stock junior to the Preferred Stock for any period unless the Preferred Stock has been paid full cash dividends in respect of the same period; provided, however, that the Company may pay dividends on Common Stock in respect of any fiscal quarter ending on or prior to June 30, 2020 (the “PIK Period”).

The holders of Preferred Stock (the “Holders”) will receive quarterly distributions equal to an annual rate of 7.0% ($70.00 per share annualized) of $1,000 per share of Preferred Stock, subject to certain adjustments (the “Liquidation Preference”). With respect to any quarter ending on or prior to the PIK Period, the Company may elect, in lieu of paying a distribution in cash, to have the amount that would have been payable if such dividend had been paid in cash added to the Liquidation Preference.

On or after the eighteen month anniversary of the Issue Date, the Holders may convert their Preferred Stock into a number of shares of Common Stock equal to, per share of Preferred Stock, the quotient of the Liquidation Preference divided by $33.00 (the “Conversion Price”), subject to certain adjustments including customary anti-dilution adjustments (such quotient, the “Conversion Rate”). Holders may elect to convert the Preferred Stock, in whole or in part, so long as the aggregate value of Common Stock to be issued pursuant to such partial conversion is not for less than $50,000,000 or a lesser amount if such conversion relates to all of a Holder’s remaining Preferred Stock.

On or after the three year anniversary of the Issue Date, if the Holders have not elected to convert all of their shares of Preferred Stock, the Company may cause the outstanding Preferred Stock to be converted into a number of shares of Common Stock equal to, per share of Preferred Stock, the quotient of the Liquidation Preference divided by the

Page 23

Notes to Unaudited Condensed Consolidated Financial Statements


9.	REDEEMABLE PREFERRED STOCK, Continued

Conversion Price, subject to certain adjustments including customary anti-dilution adjustments; provided, that in order for the Company to exercise such conversion right, the closing sale price of the Common Stock during a designated period be greater than or equal to $47.85, the resale of the shares of Common Stock issuable upon conversion shall be registered and available for resale by the Holders pursuant to a registration statement declared effective by the SEC covering such resales, the Common Stock is listed on a national securities exchange, and certain average daily trading volume minimum requirements are met. The Company may elect to convert the Preferred Stock, in whole or in part, so long as the aggregate value of Common Stock to be issued pursuant to such partial conversion is not for less than $50,000,000 or such lesser amount if such conversion relates to the aggregate amount of all remaining Preferred Stock.

Upon a change of control that involves consideration that is at least 90% cash, Holders are required to convert their shares of Preferred Stock into Common Stock at a rate equal to the greater of (i) the product of the Conversion Rate and the quotient of (a) the product of the Conversion Price and the Cash Change of Control Conversion Premium (as defined below), divided by (b) the average volume weighted average price of the Common Stock during a designated period and (ii) the Conversion Rate otherwise in effect at such time. The “Cash Change of Control Conversion Premium” equals (i) on or prior to the first anniversary of the Issue Date, 130%, (ii) after the first anniversary of the Issue Date, but on or prior to the second anniversary of the Issue Date, 120%, (iii) after the second anniversary of the Issue Date, but on or prior to the third anniversary of the Issue Date, 105%, and (iv) thereafter, 101%.

Upon a change of control that involves consideration that is less than 90% cash, Holders may elect to: (i) convert all, but not less than all, outstanding shares of Preferred Stock into Common Stock at the then-applicable Conversion Rate; (ii) except as described below, if the Company will not be the surviving person upon the consummation of such change of control, require the Company to use its commercially reasonable efforts to deliver to the Holders a security in the surviving person or the parent of the surviving person that has rights, preferences and privileges substantially similar to the Preferred Stock; provided, however, that, if the Company is unable to do so, such Holders shall be entitled to: (A) instead elect to convert shares of Preferred Stock pursuant to the mechanics described in clause (i) above or (B) require the Company to redeem all (but not less than all) of such Holder’s Preferred Stock at a price per share equal to 101% of the Liquidation Preference, with the redemption price being paid (at the Company’s option): (1) in cash or (2) in Common Stock; (iii) if the Company is the surviving person upon the consummation of such change of control, continue to hold such Holders’ shares of Preferred Stock; or (iv) require the Company to redeem all (but not less than all) of such Holder’s Preferred Stock at a cash price per share equal to the Liquidation Preference. At September 30, 2018, a change in control is not considered probable.

Holders shall be entitled to vote on all matters on which the holders of shares of Common Stock are entitled to vote and, except as otherwise provided in the Certificate of Incorporation, or by law, the Holders shall vote together with the holders of shares of Common Stock as a single class. Each Holder is entitled to a number of votes equal to the number of votes such Holder would have had if all shares of Preferred Stock held by such Holder had been converted into shares of Common Stock.

So long as any Preferred Stock is outstanding, the affirmative vote or consent of the Holders of at least 66 2/3% of the outstanding Preferred Stock, voting together as a separate class, will be necessary for effecting or validating: (i) any issuance of stock senior to the Preferred Stock, (ii) any issuance by the Company of Parity Stock, subject to certain exceptions described below, (iii) any repurchase by the Company of any Preferred Stock, other than on a pro rata basis among all Holders of Preferred Stock, (iv) any special, one-time dividend or distribution with respect to any class of junior stock and (v) any spinoff or other distribution of any equity securities or assets of any of the Company’s subsidiaries to its stockholders in which the consideration received by the Company in such transaction is less than fair market value, subject to certain exceptions. However, the foregoing rights of the Holders will not restrict any of the following actions, subject to certain terms: (i) the Company and any of its controlled affiliates entering into joint ventures with third parties, (ii) the issuance of securities, capital contributions or incurrence of intercompany indebtedness among the Company or any of its subsidiaries, or (iii) the issuance of securities, capital contributions or incurrence of intercompany indebtedness among the Company and any joint ventures, partnerships or other minority owned entities in which the Company or its subsidiaries have an equity or other interest, in each case, which exist as of the Issue Date.

Notwithstanding the vote or consent of the Holders described above, after the Issue Date, the Company may issue certain amounts of Parity Stock without the approval of the Holders if: (A) the aggregate amount of such issuances is less than or equal to $250,000,000 (excluding the aggregate amount of any additional shares of Preferred Stock issued to Warburg); or (B) the aggregate initial purchase price of the then outstanding Preferred Stock is less than $100,000,000.

9.	REDEEMABLE PREFERRED STOCK, Continued

Prior to the first anniversary of the Issue Date, no Holder may transfer any Preferred Stock without the prior written consent of the Company. Prior to the second anniversary of the Issue Date, Holders and their affiliates are prohibited from directly or indirectly engaging in any short sales or other hedging transactions involving the Preferred Stock and Common Stock underlying such Holder’s Preferred Stock.

For so long as Warburg and its affiliates collectively own 75% or more of the outstanding Preferred Stock acquired by Warburg and its affiliates on the Issue Date, the Company, prior to any issuance of Parity Stock, is required to provide Warburg with a reasonable opportunity to purchase all or any portion of such shares of Parity Stock to be issued by the Company on substantially the same terms offered to the other purchasers of such securities.

The terms of the Preferred Stock purchase agreement (the “Purchase Agreement”) contains customary representations, warranties and covenants of the Company and the Purchasers made as of the date of the Purchase Agreement and as of the Issue Date, and the parties have agreed to indemnify each other against certain losses resulting from breaches of their respective representations, warranties and covenants.

Pursuant to the Purchase Agreement, the Company has granted to Warburg, until Warburg no longer owns at least 50% of the Preferred Stock issued to Warburg and its affiliates on the Issue Date, certain rights to designate an observer (the “Board Observer”) to the board of directors of the Company (the “Board”), who shall have the right to attend full meetings of the Board (including any executive session and certain committees thereof) and receive such materials as other members of the Board receive.

In addition, pursuant to the Purchase Agreement, the Company also granted Warburg and its affiliates rights to require the Company to file and maintain, subject to the penalties described in the Purchase Agreement, registration statements with respect to the resale of the Common Stock issuable upon conversion of the Preferred Stock. The Company is required to file or cause to be filed a registration statement (the “Preferred Registration Statement”) for the resale of registrable securities and is required to cause the Preferred Registration Statement to become effective no later than the eighteen month anniversary of the Issue Date. In certain circumstances, Warburg and its affiliates will have piggyback registration rights on offerings initiated by the Company or other persons who have been granted registration rights, and Warburg has the right to request two underwritten offerings upon certain terms and conditions set forth in the Purchase Agreement. Holders of registrable securities will cease to have registration rights under the Purchase Agreement on the earlier of (i) the second anniversary of the date on which shares Preferred Stock are first converted into shares of Common Stock and (ii) the date on which no registrable securities remain outstanding; provided, that the Company shall use reasonable best efforts to maintain the effectiveness of the Preferred Registration Statement during all periods in which Warburg (A) is deemed to be an affiliate of the Company pursuant to Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”), or (B) together with its affiliates, owns more than 5% of the Company’s Common Stock (including Common Stock it would own on an as-converted basis).

On May 25, 2018, we paid-in-kind a preferred stock dividend of $4.8 million, which was prorated for the period from January 19, 2018 to March 31, 2018. On August 29, 2018, we paid-in-kind a preferred stock dividend of $6.2 million. These dividends paid-in-kind increased the Liquidation Preference such that as of September 30, 2018, the Preferred Stock was convertible into 10,940,681 shares. On October 31, 2018, we declared a preferred stock dividend to be paid-in-kind of $6.3 million, which will be paid on November 26, 2018.

11.	REVENUE FROM CONTRACTS WITH CUSTOMERS

We provide gathering, transportation, storage, distribution, marketing and other midstream services primarily to producers, refiners of petroleum products and other market participants located in the Gulf Coast, Midwest and Rocky Mountain regions of the United States of America (the “U.S.”) and Western Canada. In general, we recognize service revenue as the service is performed (“over time”) and product sales revenues are recognized when control of the product transfers to the customer (“point in time”). Our revenue from contracts with customers are disaggregated by segment as follows:

11.	REVENUE FROM CONTRACTS WITH CUSTOMERS, Continued

Crude Transportation


•	Crude Transportation generates revenue by providing crude oil pipeline and truck transportation services to customers under fee-based contractual arrangements generally based on units of volume transported. In some instances fees are fixed and not dependent on usage, such as take-or-pay arrangements.

Crude Facilities


•	Crude Facilities generates revenue by providing crude oil storage and terminalling services primarily to customers at the Cushing Hub under fee-based contractual arrangements that, in some instances are fixed and not dependent on usage. Pump-over and unloading fees are based on per volume fees for units delivered or withdrawn.

Crude Supply and Logistics

•

Crude Supply and Logistics performs marketing activities including purchasing crude oil for its own account from producers and aggregators and selling to traders and refiners under contracts generally with initial terms of less than one year. Revenue is recognized based on market prices at the time the commodities are sold. In certain transactions, we purchase inventory from, and sell inventory to, the same counterparty. Such transactions that are entered into in contemplation of one another are recorded on a net basis.

HFOTCO


•	HFOTCO generates revenue by providing storage and terminalling services to customers in the Houston Ship Channel. These contractual arrangements typically include fixed take-or-pay fees related to provision of storage and throughput capacity and usage based charges for pump-over, heating, berthing and excess throughput volumes.


•	HFOTCO also generates revenue from leases of certain land, tanks and a barge dock, which are accounted for as a direct financing lease and are outside of the scope of ASC 606.

SemGas

•

SemGas generates revenue by providing natural gas and natural gas liquids gathering and processing services to customers based on agreements that are a combination of percent of proceeds and fee-based contracts. Initial contract terms can range from monthly and interruptible to the life of the reserves and, upon expiration, continue to renew on a month-to-month or year-to-year evergreen basis. SemGas’ customers include producers, operators, marketers and traders. Gathering and processing fees are generally based on per volume fees. Product sales revenue is generated from the sale of NGLs and residue gas arising from processing at prevailing market prices.

SemCAMS

•

SemCAMS generates revenue from its processing plants through volumetric fees for services under contractual arrangements with working interest owners and third-party customers and the pass through of certain operating costs. Pass-through cost recoveries are reported as "Other revenue" in the consolidated statements of operations and comprehensive income (loss). SemCAMS also derives revenue as the owner and operator of pipeline gathering systems that gather gas from multiple wells located in the same production unit and as the owner and operator of pipeline transportation systems that deliver the gathered gas to its processing plant. SemCAMS’ customers include producers of varying sizes. To support operations at our plants, several producers have committed to process all of their current and future natural gas production.

Corporate and Other


•	Corporate and Other is not an operating segment, but contains the results of operations for our former Mexican asphalt business and U.K. storage business, which are not significant components of our business.

Key areas of judgment

Take or pay

Contracts with take-or-pay provisions are recognized over time as the customer simultaneously receives and consumes the benefit of available capacity. Payments made for unused take-or-pay capacity, which allow the customer to carryforward a portion of the unused capacity to future periods, are deferred until it becomes unlikely that the capacity will be used prior to contract expiration. Determining when, or if, the capacity will be used requires judgment.

Percentage of proceeds

Contracts with percentage of proceeds terms typically involve the receipt of natural gas at the wellhead and include gathering, processing and marketing of the resulting NGLs and residue gas with SemGroup retaining a portion of the proceeds from the ultimate sale to a third-party. The terms of these agreements include various gathering and processing fees. The determination of whether the transaction is a purchase at the wellhead by SemGroup with gathering and processing performed on our own account or whether the transaction represents gathering and processing as a service provided to the producer by SemGroup with a purchase and sale of processed gas at the completion of the service, requires judgment and is impacted by when control of the underlying commodity has been deemed to move from the producer to the processor. This determination impacts whether gathering and processing fees are recorded as reductions to cost of sales or recorded as service revenue.

Principal vs. agent

We engage in various types of transactions where we perform marketing activities for producers, such as our percentage of proceeds contracts, or transactions where costs are incurred and reimbursed by customers or other owners in facilities, such as SemCAMS' pass-through costs. These types of transactions require judgment to determine whether we are the principal or an agent in the transaction and as a result whether revenues are recorded gross or net.

Non-cash consideration

SemGroup receives commodities from its customers in the form of plant and field fuel, pipeline loss allowance and retention of drip liquids. The purpose of the receipt of these commodities is to keep the Company whole in the case of minor operational usage or loss of product and is not intended as a consideration for services performed. Therefore, the receipt of these commodities does not represent consideration and is not recorded as revenue. Any net retention of commodities in excess of actual losses is recorded in inventory and recognized as revenue when sold.

Tiered pricing and material rights

We have certain contracts that provide customers with rates that reduce incrementally as volumes increase beyond certain thresholds. These types of agreements require judgment to determine if the option for the customer to acquire additional services constitutes a material right that the customer would not receive without entering into the contract, e.g. the discount exceeds the range of discounts typically given. If it is determined that a material right exists, a portion of the revenue is allocated to that right at contract inception and recognized as revenue as the option for additional services is exercised or when the option expires. In contrast, if it is concluded that the option to acquire additional services reflects standalone selling price, this would constitute a marketing offer and not a material right.

Remaining performance obligations

Most of our service contracts are such that we have the right to consideration from a customer in an amount that corresponds directly with the value to the customer of our performance completed to date. Therefore, we are utilizing the practical expedient in ASC 606-10-55-18 under which we recognize revenue in the amount to which we have the right to invoice. Applying this practical expedient, we are not required to disclose the transaction price allocated to remaining performance obligations under these agreements. However, certain of our agreements, such as "take-or-pay" agreements, do not qualify for the practical expedient. The amount and timing of revenue recognition for such contracts is presented below (in thousands):



	2018		2019		2020		2021		2022		Thereafter
Expected timing of revenue recognized for remaining performance obligations	$	80,242	$	256,782	$	217,510	$	173,283	$	161,903	$	1,387,769

For our product sales contracts, we have elected the practical expedient set out in ASC 606-10-50-14A that states that we are not required to disclose the transaction price allocated to remaining performance obligations if the variable consideration is allocated entirely to a wholly unsatisfied performance obligation. Under these agreements, each unit of

Page 29

11.	REVENUE FROM CONTRACTS WITH CUSTOMERS, Continued

product represents a separate performance obligation and therefore future volumes are wholly unsatisfied and disclosure of transaction price allocated to remaining performance obligations is not required. Under product sales contracts, the variability arises as both volume and pricing (typically index based) are not known until the product is delivered.

Receivables from contracts with customers

Accounts receivable, net on the condensed consolidated balance sheets represents current receivables from contracts with customers. Certain noncurrent receivables from contracts with customers are included in “other noncurrent assets” on the condensed consolidated balance sheets. These amounts are accruals to recognize revenue for performance to date related to customer deficiencies on minimum volume commitments with make-up rights for which the use of the make-up rights are not probable due to capacity constraints or other factors. Therefore, we have accrued the amount for which no future performance by SemGroup will be required, but for which we do not have a present right to bill the customer until the end of the contract. The balance of noncurrent receivables from customer contracts was (in thousands):



	September 30, 2018		December 31, 2017
Noncurrent receivables	$	10,368	$	—

Noncurrent receivables for the transactions described above were not recorded prior to the adoption of ASC 606 as our policy was to defer recognition of deficiencies with make-up rights until the contractual make-up rights expired.

Deferred revenue

We record deferred revenue when we have received a payment in advance of delivering a product or performing a service. For the three months and nine months ended September 30, 2018, we recognized $0.4 million and $3.6 million, respectively, of revenue which was included in deferred revenue at the beginning of the period.

Costs to obtain or fulfill a contract

Unless material, we expense costs to obtain or fulfill a contract in the period incurred. At September 30, 2018, we had contract assets of $9.5 million related to costs incurred to obtain contracts which had been expensed as incurred under previous guidance. These costs are reported within “other noncurrent assets” on the condensed consolidated balance sheets and are being amortized straight-line over the 25-year life of the related contracts.


12.	SEGMENTS

Our businesses are organized based on the nature and location of the services they provide. Certain summarized information related to our reportable segments is shown in the tables below. None of the operating segments have been aggregated. Although Corporate and Other does not represent an operating segment, it is included in the tables below to reconcile segment information to that of the consolidated Company. Prior period segment disclosures have been recast to include the former SemMexico and SemLogistics segments within Corporate and Other, as these businesses are no longer significant and are not expected to be significant in the future. These businesses were sold during the nine months ended September 30, 2018. Eliminations of transactions between segments are also included within Corporate and Other in the tables below.

During the fourth quarter of 2017, we changed our definition of segment profit to focus on the results of each segment exclusive of general and administrative costs and related overhead allocations. Segment Profit is defined as revenue, less cost of products sold (exclusive of depreciation and amortization) and operating expenses, plus equity earnings and is adjusted to remove unrealized gains and losses on commodity derivatives and to reflect equity earnings on an earnings before interest, taxes and depreciation and amortization (“EBITDA”) basis. Reflecting equity earnings on an EBITDA basis is achieved by adjusting equity earnings to exclude our percentage of interest, taxes, depreciation and amortization from equity earnings for operated equity method investees. For our investment in NGL Energy, we exclude equity earnings and include cash distributions received. Prior period segment profit has been recast to be consistent with the revised definition.

13.	EARNINGS PER SHARE

Basic earnings per share is based on net income (loss) attributable to common shareholders, which is calculated as net income (loss) less cumulative preferred stock dividends. Diluted earnings per share includes the dilutive effect of unvested equity compensation awards and the potential conversion of preferred stock, if dilutive.

The following summarizes the calculation of basic earnings per share for the three months and nine months ended September 30, 2018 and 2017 (in thousands, except per share amounts):

15.	RELATED PARTY TRANSACTIONS

Transactions with NGL Energy and its subsidiaries primarily relate to crude oil marketing, leased storage and transportation services, including buy/sell transactions. Transactions with White Cliffs primarily relate to leased storage, purchases and sales of crude oil, transportation fees for shipments on the White Cliffs Pipeline, and management fees.

In accordance with ASC 845-10-15, the buy/sell transactions with NGL Energy and White Cliffs were reported as revenue on a net basis in our condensed consolidated statements of operations and comprehensive income (loss) because the purchases of inventory and subsequent sales of the inventory were with the same counterparty and entered into in contemplation of one another.

During the three months and nine months ended September 30, 2018 and 2017, we generated the following transactions with related parties (in thousands):

16.	CONDENSED CONSOLIDATING GUARANTOR FINANCIAL STATEMENTS

Our senior unsecured notes are guaranteed by certain of our subsidiaries as follows: Rose Rock Finance Corporation, Rose Rock Midstream Operating, LLC, Rose Rock Midstream Energy GP, LLC, Rose Rock Midstream Crude, L.P., Rose Rock Midstream Field Services, LLC, SemGas, L.P., SemMaterials, L.P., SemGroup Europe Holding, L.L.C., SemOperating G.P., L.L.C., SemMexico, L.L.C., SemDevelopment, L.L.C., Mid-America Midstream Gas Services, L.L.C., SemCrude Pipeline, L.L.C., and Wattenberg Holding, LLC (collectively, the “Guarantors”).

As of June 30, 2018, Beachhead Holdings LCC, Beachhead I LLC and Beachhead II LLC were added to the Guarantors and Glass Mountain Holding, LLC had been removed as a guarantor. Accordingly, prior period financial information below has been recast to reflect these changes.

Each of the Guarantors is 100% owned by SemGroup Corporation (the “Parent”). Such guarantees of our senior unsecured 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. Distributions of cash flows from HFOTCO, a non-guarantor, are restricted by the existing indebtedness of HFOTCO. 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.

Unaudited condensed consolidating financial statements for the Parent, the Guarantors and non-guarantors as of September 30, 2018 and December 31, 2017, and for the three months and nine months ended September 30, 2018 and 2017, 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 notes 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. These balances are eliminated through consolidating adjustments below.

Revenue and Expenses

Revenue and expenses are analyzed by operating segment below.

Operating expense

Operating expense increased in the three months ended September 30, 2018, to $64.8 million from $62.7 million in the three months ended September 30, 2017, primarily due to a partial quarter of HFOTCO operations in the prior year partially offset due to lower current year costs due to the disposal of our Mexican asphalt and UK operations. Operating expense increased in the nine months ended September 30, 2018, to $224.9 million from $188.1 million in the nine months ended September 30, 2017, primarily due to the prior year acquisition of HFOTCO partially offset due to lower current year costs due to the disposal of our Mexican asphalt and UK operations.

Table of Contents

General and administrative expense

General and administrative expense decreased in the three months ended September 30, 2018, to $21.9 million from $38.4 million in the three months ended September 30, 2017. General and administrative expense decreased in the nine months ended September 30, 2018, to $71.3 million from $86.9 million in the nine months ended September 30, 2017. The decreases were primarily due to the disposal of our Mexican asphalt and U.K. storage businesses and non-recurring prior year costs related to the acquisition of HFOTCO. These decreases were partially offset by on-going general and administrative costs related to HFOTCO subsequent to acquisition.

Depreciation and amortization expense

Depreciation and amortization expense increased in the three months ended September 30, 2018, to $53.6 million from $50.1 million in the three months ended September 30, 2017. Depreciation and amortization expense increased in the nine months ended September 30, 2018, to $155.9 million from $100.3 million in the nine months ended September 30, 2017. The increases in both periods were primarily as a result of the acquisition of HFOTCO and completion of the Maurepas Pipeline.

Loss (gain) on disposal or impairment, net

We incurred a net gain on disposal or impairment for the three months ended September 30, 2018, of $0.4 million compared to a net loss of $41.6 million on disposal or impairment for the three months ended September 30, 2017. We incurred a net gain on disposal or impairment for the nine months ended September 30, 2018, of $2.1 million compared to a net loss of $43.8 million on disposal or impairment for the nine months ended September 30, 2017. The losses in both periods in 2017 were due to goodwill and intangible asset impairments related to our crude oil trucking operations.

Interest expense

Interest expense increased in the three months ended September 30, 2018, to $35.3 million from $32.7 million in the three months ended September 30, 2017. Interest expense increased in the nine months ended September 30, 2018, to $113.7 million from $60.1 million in the nine months ended September 30, 2017. In the three months, the increase in interest expense is primarily due to incremental debt outstanding as a result of the HFOTCO acquisition. In the nine months, the increase in interest expense is primarily due to incremental debt outstanding as a result of the HFOTCO acquisition and interest on our senior unsecured notes.

Loss on early extinguishment of debt

During the nine months ended September 30, 2017, we recognized a loss of $19.9 million on the early extinguishment of our senior unsecured noted due 2021, which included premiums of $15.9 million and the write off of $3.6 million of associated unamortized debt issuance costs.

Foreign currency transaction loss

Foreign currency transaction loss for the nine months ended September 30, 2018, is primarily due to foreign currency forwards to purchase Canadian dollars to limit exposure to foreign currency rate fluctuations for capital contributions to our Canadian operations.

Income tax expense (benefit)

We reported an income tax expense of $16.8 million for the nine months ended September 30, 2018, compared to a benefit of $33.5 million for the nine months ended September 30, 2017. The effective tax rate was (159)% and 63% for the nine months ended September 30, 2018 and 2017, respectively. The rate for the nine months ended September 30, 2018, is impacted by a discrete tax expense related to the vesting of restricted stock in the amount of $1.7 million, a discrete tax expense of $10.0 million in Mexico on the sale of the 100% equity interest in our Mexican asphalt business, and a discrete tax expense of $2.7 million on the foreign tax deduction offset to branch deferreds on the sale of our U.K. operations. The rate is also affected by the U.S. deduction for foreign taxes. The rate for the nine months ended September 30, 2017, is impacted by a discrete tax expense related to the vesting of restricted stock in the amount of $1.4 million. Significant items that impacted the effective tax rate for each period, as compared to the U.S. federal statutory rate of 21%, include earnings in foreign jurisdictions taxed at different rates and foreign earnings taxed in foreign jurisdictions as well as in the U.S., since they are disregarded entities for U.S. federal income tax purposes. These combined factors, and the magnitude of the permanent items impacting the tax rate relative to income from continuing operations before income taxes, result in rates that are not comparable between the periods.

Three months ended September 30, 2018 versus three months ended September 30, 2017

Revenue

Pipeline transportation revenue increased to $22.4 million in the three months ended September 30, 2018, from $12.5 million in the three months ended September 30, 2017. The increase was primarily the result of $9.1 million related to the Maurepas Pipeline which started operations in the third quarter of 2017 and a $0.7 million increase on the WOT.

Truck transportation revenue decreased to $12.5 million in the three months ended September 30, 2018, from $15.3 million for the same period in 2017 as a result of lower volumes.

Operating expense

Operating expense decreased slightly to $16.3 million in the three months ended September 30, 2018, compared to $17.3 million for the three months ended September 30, 2017. The decrease was primarily the result of lower outside service costs.

Earnings from equity method investments

Crude Transportation’s earnings from equity method investments decreased in the three months ended September 30, 2018, to $14.5 million from $17.4 million in the three months ended September 30, 2017, primarily due to the sale of Glass Mountain Pipeline in December 2017, as well as rate reductions on White Cliffs Pipeline, partially offset by higher volumes.

Adjustments to reflect equity earnings on an EBITDA basis

Segment profit adjusts earnings from our equity method investments to exclude our proportional share of our equity investee’s depreciation and amortization expense. The decrease as compared to the prior period is primarily due to the sale of Glass Mountain Pipeline in December 2017.

Nine months ended September 30, 2018 versus nine months ended September 30, 2017

Revenue

Pipeline transportation revenue increased to $66.2 million in the nine months ended September 30, 2018, from $25.1 million in the nine months ended September 30, 2017. The increase was primarily the result of $38.1 million related to the Maurepas Pipeline, which started operations in the third quarter of 2017, and a $3.2 million increase on the WOT and a $0.1 million reduction to intersegment transportation attributed to our Crude Supply and Logistics segment, offset by a $0.2 million reduction in volumes.

Truck transportation revenue decreased to $38.5 million in the nine months ended September 30, 2018, from $44.1 million for the same period in 2017 as a result of lower volumes.

Operating expense

Operating expense slightly increased to $50.6 million in the nine months ended September 30, 2018, compared to $49.7 million for the nine months ended September 30, 2017. The increase was primarily the result of increases on our Maurepas Pipeline, partially offset by lower outside service costs.

Earnings from equity method investments

Crude Transportation’s earnings from equity method investments decreased in the nine months ended September 30, 2018, to $41.5 million from $52.2 million in the nine months ended September 30, 2017, primarily due to the sale of Glass Mountain Pipeline in December 2017, as well as rate reductions on White Cliffs Pipeline, partially offset by higher volumes.

Gross product revenue increased in the three months ended September 30, 2018, to $1.5 billion from $1.1 billion in the three months ended September 30, 2017. The increase was primarily due to a higher average sales price of $70 per barrel on lower volume sold of 22.1 million barrels in the three months ended September 30, 2018, compared to an average sales price of $47 per barrel on volume sold of 22.2 million barrels in the three months ended September 30, 2017.

Gross product revenue was reduced by $1.1 billion and $0.7 billion during the three months ended September 30, 2018 and 2017, respectively, in accordance with Accounting Standards Codification (“ASC”) 845-10-15, “Nonmonetary Transactions”. ASC 845-10-15 requires that certain transactions -- those where inventory is purchased from a customer then resold to the same customer -- to be presented in the income statement on a net basis, resulting in a reduction of revenue and costs of products sold by the same amount.

Costs of products sold

Costs of products sold increased in the three months ended September 30, 2018, to $435.7 million (including $10.5 million of intersegment transportation and facility expense) from $342.3 million in the three months ended September 30, 2017 (including $11.6 million of intersegment transportation and facility expense).

HFOTCO generates revenue by providing storage and terminalling services to customers in the Houston Ship Channel. These contractual arrangements typically include fixed take-or-pay fees related to provision of storage and throughput capacity and usage based charges for pump-over, heating, berthing and excess throughput volumes. HFOTCO also generates revenue from leases of certain land, tanks and a barge dock which are accounted for as a direct financing lease.

HFOTCO was acquired in July 2017; therefore no comparisons are given below for the nine months ended September 30, 2018 versus the same period in 2017.

Three months ended September 30, 2018 versus three months ended September 30, 2017

Revenue

Revenue increased to $49.7 million in the three months ended September 30, 2018, from $34.7 million for the three months ended September 30, 2017. The increase was primarily due to $7.4 million due to 2018 being a full quarter versus 2.5 months only in 2017 (numbers above reflect purchase date in mid-July 2017 to September 30, 2017), $4.6 million from new crude tanks going into service in the third quarter of 2018 and other revenue of $3.0 million.

Operating expense

Operating expense increased to $13.6 million in the three months ended September 30, 2018, from $6.2 million for the three months ended September 30, 2017, as a result of increases of $2.8 million in other expenses, $2.7 in maintenance and other expense and $1.9 as a result of a full third quarter in 2018 versus a partial quarter of operational results in 2017.

Three months ended September 30, 2018 versus three months ended September 30, 2017

Revenue

Product sales revenue increased in the three months ended September 30, 2018, to $57.8 million from $43.5 million in the three months ended September 30, 2017. The increase is primarily due to higher volumes (37,006 MMcf in the three months ended September 30, 2018, compared to 25,120 MMcf for the same period in 2017) and higher average NGL basket price of $0.91/gallon in the three months ended September 30, 2018, versus $0.88/gallon for the same period in 2017. The increase was offset by lower average natural gas NYMEX price of $2.90/MMbtu in the three months ended September 30, 2018, versus $2.99/MMbtu for the same period in 2017. Volume increases are primarily due to Stack production, offset by reduced Mississippi Lime drilling, coupled with natural well production declines.

Gathering and processing fee revenue increased in the three months ended September 30, 2018, to $18.7 million from $12.7 million in the three months ended September 30, 2017. In the current year, certain fees are reported as gathering and processing fee revenue under ASU 2016-15 - “Revenue from Contracts with Customers” (“ASC 606”), whereas in the prior year these amounts were reported as reductions to cost of sales under ASC 605. The current year includes $4.7 million of fee revenue which would have been included as a reduction to cost of sales under the prior year methodology. Exclusive of the impact of ASC 606, gathering and processing fee revenues are down although volumes are up, due to contract mix.

Costs of products sold

Costs of products sold increased to $48.3 million in the three months ended September 30, 2018, from $33.1 million in the three months ended September 30, 2017. The increase was primarily due to higher NGL prices, the impact of ASC 606 discussed above, offset by lower Mississippi Lime volumes and lower natural gas prices.

Table of Contents

Operating expense

Operating expense increased slightly to $8.4 million in the three months ended September 30, 2018, from $7.6 million in the three months ended September 30, 2017. This increase was primarily due to compressor maintenance and employee costs.

Nine months ended September 30, 2018 versus nine months ended September 30, 2017

Revenue

Product sales revenue increased in the nine months ended September 30, 2018, to $142.3 million from $135.4 million in the nine months ended September 30, 2017. The increase is primarily due to higher average NGL basket price of $0.90 gallon in the nine months ended September 30, 2018, versus $0.83/gallon for the same period in 2017 and higher volumes (99,269 MMcf in the nine months ended September 30, 2018, compared to 77,773 MMcf for the same period in 2017). Volume increases are primarily due to Stack production, offset by reduced Mississippi Lime drilling, coupled with natural well production declines. The increase was offset by lower average natural gas NYMEX price of $2.90/MMbtu in the nine months ended September 30, 2018, versus $3.17/MMbtu for the same period in 2017

Gathering and processing fee revenue increased in the nine months ended September 30, 2018, to $52.5 million from $40.9 million in the nine months ended September 30, 2017. In the current year, certain fees are reported as gathering and processing fee revenue under ASC 606, whereas in the prior year these amounts were reported as reductions to cost of sales under ASC 605. The current year includes $12.5 million of fee revenue which would have been included as a reduction to cost of sales under the prior year methodology. Exclusive of the impact of ASC 606, gathering and processing fee revenues are down although volumes are up, due to contract mix.

Costs of products sold

Costs of products sold increased to $120.2 million in the nine months ended September 30, 2018, from $100.7 million in the nine months ended September 30, 2017. The increase was primarily due to the impact of ASC 606 discussed above and higher NGL prices, offset by lower natural gas prices and lower Mississippi Lime volumes.

Operating expense

Operating expense increased to $25.0 million in the nine months ended September 30, 2018, from $22.3 million in the nine months ended September 30, 2017. This increase was primarily due to compressor and turbine maintenance.

Three months ended September 30, 2018 versus three months ended September 30, 2017

Revenue

Revenue increased to $41.9 million in the three months ended September 30, 2018, from $39.5 million in the three months ended September 30, 2017. This increase is primarily due to higher gathering and processing revenue of $3.7 million. This was offset by changes in foreign currency exchange rates between periods and other revenues of $1.7 million and $0.7 million, respectively.

Page 51

Table of Contents

Additionally, subsequent to the adoption of ASC 606, we recognized $1.1 million of revenue in the three months ended September 30, 2018, to recognize certain deficiencies on take-or-pay agreements for which there is a contractual make-up period. Under ASC 605, revenue related to deficiencies with a make-up period was deferred until the contractual right to make up a deficiency expired. Under ASC 606, we can recognize all or a portion of revenue related to deficiencies before the make-up period expires if we determine that it is probable that the customer will not make-up all or some of its deficient volumes, for example if there is insufficient capacity to make up the deficient volumes in future periods.

Operating expense

Operating expense decreased in the three months ended September 30, 2018, to $21.4 million from $22.8 million in the three months ended September 30, 2017. This decrease is primarily due to turnaround costs and changes in foreign currency exchange rates between periods of $5.3 million and $0.9 million, respectively. These decreases were offset, in part, by higher greenhouse gas credit purchases, higher power costs and higher contractor costs of $1.5 million, $1.5 million and $1.5 million, respectively.

Nine months ended September 30, 2018 versus nine months ended September 30, 2017

Revenue

Revenue increased in the nine months ended September 30, 2018, to $156.7 million from $136.4 million in the nine months ended September 30, 2017. This increase is primarily due to higher operating costs recoveries, higher gathering and processing revenue and changes in foreign currency exchange rates between periods of $10.2 million, $8.2 million and $3.0 million, respectively. These increases were offset, in part, by a 2017 true-up of take-or-pay minimum volumes commitments of $3.9 million. Further a 31-day planned outage at the KA plant in 2018 decreased gathering and processing revenue by $2.2 million. This was offset by the 2017 planned outage at the K3 plant which decreased gathering and processing revenue by $2.5 million.

Additionally, subsequent to the adoption of ASC 606, we recognized $3.4 million of revenue in the three months ended September 30, 2018, to recognize certain deficiencies on take-or-pay agreements for which there is a contractual make-up period. Under ASC 605, revenue related to deficiencies with a make-up period was deferred until the contractual right to make up a deficiency expired. Under ASC 606, we can recognize all or a portion of revenue related to deficiencies before the make-up period expires if we determine that it is probable that the customer will not make-up all or some of its deficient volumes, for example if there is insufficient capacity to make up the deficient volumes in future periods.

Operating expense

Operating expense increased in the nine months ended September 30, 2018, to $92.4 million from $83.7 million in the nine months ended September 30, 2017. This increase is primarily due to turnaround costs related to the KA plant, higher greenhouse gas credit purchases, higher power costs, changes in foreign currency exchange rates between periods and higher contractor costs of $25.6 million, $4.6 million, $3.5 million, $2.1 million and $0.9 million, respectively. These increases were offset, in part, by turnaround costs in 2017 for the K3 plant of $28.2 million.

Earnings from equity method investments relate to our general partner interest in NGL Energy.

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 facility. The consolidated cash balance on September 30, 2018, was $70.0 million. Of this amount, $16.8 million was held in Canada and portions 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, debt payments and our quarterly dividends. In general, we expect to fund:


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


•	expansion capital expenditures and any working capital deficits through cash on hand, borrowings under our revolving credit facility and the issuance of debt securities and equity securities and proceeds from the divestiture of assets or interests in assets;


•	acquisitions through cash on hand, borrowings under our revolving credit facility, the issuance of debt securities and equity securities and proceeds from the divestiture of assets or interests in assets; and


•	debt principal payments through cash from operating activities and refinancing when our revolving and term loan B 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. 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 cash outlays, such as expansion capital expenditures and potential future acquisitions.

We believe our cash from operations, our remaining borrowing capacity and other capital markets activity allow us to manage our day-to-day cash requirements, distribute our quarterly dividends and meet our capital expenditures commitments for the coming year.

Adjustments to net loss for non-cash expenses, net increased $39.0 million to $174.0 million for the nine months ended September 30, 2018, from $135.1 million for the nine months ended September 30, 2017. This change is primarily a result of:


•	$55.6 million in depreciation and amortization expense, primarily as a result of the acquisition of HFOTCO and completion of the Maurepas Pipeline;


•	$39.6 million change in deferred income tax expense (benefit);


•	$10.7 million reduction in earnings from equity method investments due to the sale of Glass Mountain Pipeline in December 2017, as well as rate reductions on White Cliffs Pipeline partially offset by higher volumes;


•	$6.4 million higher currency exchange losses in the current year primarily due to foreign currency forwards to purchase Canadian dollars to limit exposure to foreign currency rate fluctuations for capital contributions to our Canadian operations; and


•	$3.0 million due to a non-recurring prior year gain on the curtailment of the HFOTCO pension plan subsequent to acquisition.

These increases to the adjustments to net income for non-cash expenses, net were offset by decreases due to:


•	$45.9 million increase in gains on disposal or impairments, net, primarily due to a current year gain of $1.6 million from the sale of our Mexican asphalt business and the $1.4 million post-closing adjustment related to our prior year Glass Mountain Pipeline disposal and compared to prior year goodwill and intangible asset losses related to our crude oil trucking operations;


•	$19.9 million decrease related to a prior year loss on early extinguishment of $300 million of senior unsecured notes; and


•	$10.1 million decrease in distributions from equity investments due to our prior year disposal of our investment in Glass Mountain Pipeline.

Page 54

Table of Contents

All other adjustments to net income for non-cash expenses, net for the nine months ended September 30, 2018, remained relatively comparable to the nine months ended September 30, 2017.

Changes in operating assets and liabilities for the nine months ended September 30, 2018, generated a net decrease in operating cash flows of $10.3 million. The decrease to operating cash flow due to the change in operating assets and liabilities was primarily a result of a decrease in inventories of $57.5 million, respectively, offset by increases in accounts receivable, other current assets and other assets of $14.8 million, $4.0 million and $3.1 million, respectively. Liabilities decreased $37.5 million in accounts payable and accrued liabilities and $5.6 million in payables to affiliates. Changes in receivables, inventory, payables and accrued liabilities are primarily due to our segments’ operating activities and are subject to the timing of purchases and sales and fluctuations in commodity pricing.

Changes in operating assets and liabilities for the nine months ended September 30, 2017, generated a net decrease in operating cash flows of $22.9 million. The decrease to operating cash flow due to the change in operating assets and liabilities was primarily a result of an increase in assets related to accounts receivable, inventories, other assets and other current assets of $36.2 million, $28.3 million, $17.7 million and $3.4 million, respectively, offset by a decrease in receivables from affiliates of $19.9 million. Liabilities increased $57.1 million in accounts payable and accrued liabilities and $7.4 million in other noncurrent liabilities, offset by a decrease in payables to affiliates of $21.6 million. The increase in other noncurrent liabilities is primarily due to the accretion of the final payment related to the HFOTCO acquisition. Changes in receivables, inventory, payables and accrued liabilities are primarily due to our segments’ operating activities and are subject to the timing of purchases and sales and fluctuations in commodity pricing.

Investing Activities

For the nine months ended September 30, 2018, we had net cash outflows of $148.1 million from investing activities, due primarily to $303.4 million in capital expenditures and $7.5 million of contributions to equity method investments. These cash outflows were offset by investing cash inflows of $146.7 million in proceeds primarily from the sale of our Mexican asphalt and U.K. storage businesses and $15.7 million of distributions in excess of equity in earnings of affiliates. Capital expenditures primarily related to expansion projects at our SemCAMS and HFOTCO segments. Distributions in excess of equity in earnings of affiliates represent cash distributions from White Cliffs in excess of our cumulative equity in earnings and are accounted for as a return of investment.

For the nine months ended September 30, 2017, we had net cash outflows of $622.1 million from investing activities, due primarily to $346.2 million of capital expenditures, $293.0 million in payments to acquire HFOTCO, net of cash received and $18.8 million of contributions to equity method investments. These cash outflows were offset by investing cash inflows of $19.3 million of distributions in excess of equity in earnings of affiliates and $16.6 million in proceeds from the sale of long-lived assets. Capital expenditures primarily related to the Maurepas Pipeline. Contributions to equity method investments primarily related to Glass Mountain growth projects. Proceeds from the sale of long-lived assets related to the sale of non-core assets. 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.

Financing Activities

For the nine months ended September 30, 2018, we had net cash outflows of $11.5 million from financing activities, which related to principal payments on credit facilities and other obligations of $1,376.6 million, dividends paid of $111.4 million and debt issuance costs of $4.7 million, offset by borrowings on credit facilities of $1,139.5 million and proceeds from the issuance of preferred stock, net of offering costs, of $342.3 million. Principal payments on credit facilities and other obligations include the final payment related to the HFOTCO acquisition of $579.6 million and activity related to the amendment and restatement of HFOTCO’s credit agreement.

For the nine months ended September 30, 2017, we had net cash inflows of $519.0 million from financing activities, which related to borrowings on credit facilities and the issuance of senior unsecured notes, net of discount, of $1.4 billion, offset by principal payments on credit facilities and other obligations of $711.9 million, dividends paid of $94.7 million, debt extinguishment costs of $16.3 million, debt issuance costs of $10.8 million and $1.4 million to repurchase common stock for payment of statutory taxes due on equity-based compensation. Net borrowings were used primarily to extinguish senior unsecured notes, acquire HFOTCO and for capital expenditures. Debt issuance costs related to the issuance of senior unsecured notes.

Long-term Debt

Senior Unsecured Notes

Page 55

Table of Contents

At September 30, 2018, we had outstanding $400 million of 5.625% senior unsecured notes due 2022, $350 million of 5.625% senior unsecured notes due 2023, $325 million of 6.375% senior unsecured notes due 2025 and $300 million of 7.25% senior unsecured notes due 2026.

SemGroup Revolving Credit Facility

At September 30, 2018, we had $460 million of cash borrowings outstanding under our $1.0 billion revolving credit facility. We had $28.3 million in outstanding letters of credit on that date. The maximum letter of credit capacity under this facility is $250 million. The facility can be increased up to $300 million. The credit agreement expires on March 15, 2021.

At September 30, 2018, we had available borrowing capacity of $511.7 million under this facility.

At September 30, 2018, our net leverage ratio was 4.8:1. Our net leverage ratio, net debt to EBITDA, is calculated per the senior secured credit facility definitions, which includes a pro-rata portion of projected future annual EBITDA from material projects. Our maximum net leverage ratio under the senior secured credit facility is 5.5:1.

HFOTCO long-term debt

On June 26, 2018, we restated and amended the HFOTCO credit agreement. The aggregate term loans incurred thereunder was increased to $600 million and the revolving credit facility was terminated. The term loan is due in quarterly installments of $1.5 million with a final payment due on June 26, 2025. In addition, HFOTCO may incur additional term loans in an aggregate amount not to exceed the greater of $120 million and a measure of HFOTCO’s EBITDA, defined in the credit agreement, at the time of determination, plus additional amounts subject to satisfaction of certain leverage-based criteria, subject to receiving commitments for such additional term loans from either new lenders or increased commitments from existing lenders.

At September 30, 2018, HFOTCO had $598.5 million outstanding under its Term Loan B and $225 million outstanding of tax exempt notes payable due 2050.

HFOTCO acquisition final payment

On April 17, 2018, we made the final payment related to the HFOTCO acquisition in the amount of $579.6 million. The payment was funded through revolving credit facility borrowings and cash on hand.

Series A Convertible Preferred Stock

On January 19, 2018, we sold, to certain institutional investors in a private placement, an aggregate of 350,000 shares of our Series A Cumulative Perpetual Convertible Preferred Stock, par value $0.01 per share (the “Preferred Stock”), convertible into 10,606,061 shares (subject to adjustment) of our Class A common stock, for a cash purchase price of $1,000 per share of Preferred Stock and aggregate gross proceeds to us of $350 million. These proceeds were used to repay amounts borrowed under our credit agreement, to fund growth capital expenditures and for general corporate purposes. Holders of the Preferred Stock (the “Holders”) will receive quarterly distributions equal to an annual rate of 7.0% ($70.00 per share annualized) of $1,000 per share of Preferred Stock, subject to certain adjustments (the “Liquidation Preference”). With respect to any quarter ending on or prior to June 30, 2020, we may elect, in lieu of paying a distribution in cash, to have the amount that would have been payable if such dividend had been paid in cash added to the Liquidation Preference. On or after the eighteen month anniversary of January 19, 2018, the Holders may convert their shares of Preferred Stock into a number of shares of our Class A common stock equal to, per preferred share, the quotient of the Liquidation Preference divided by $33.00, subject to certain adjustments including customary anti-dilution adjustments. On or after January 19, 2021, if the Holders have not elected to convert all of their shares of Preferred Stock, we may cause, under certain circumstances, the outstanding shares of Preferred Stock to be converted into shares of our Class A common stock. Holders are entitled to vote on all matters on which the holders of shares of our Class A common stock are entitled to vote and will, in general, vote together with the holders of shares of our Class A common stock as a single class. Each Holder is entitled to a number of votes equal to the number of votes such Holder would have had if all shares of Preferred Stock held by such Holder had been converted into shares of our Class A common stock.

Shelf Registration Statement

We have access to a universal shelf registration statement which provides us 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 March 2019.

Page 56

Table of Contents

We have also established an “at the market” offering program under this shelf registration statement, which provides for the offer and sale, from time to time, of common shares having an aggregate offering price of up to $300 million. We are able to make sales over a period of time and from time to time in transactions at prices which are prevailing market prices at the time of sale, prices related to market prices or at negotiated prices. Such sales may be made pursuant to an Equity Distribution Agreement between us and certain agents who may act as sales agents or purchase for their own accounts as principals. To date, there have been no such sales.

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 2018 are estimated at $320 million in expansion projects, including capital contributions to affiliates for funding growth projects and acquisitions, and $40 million in maintenance projects. These estimates may change as future events unfold. See “Cautionary Note Regarding Forward-Looking Statements.” During the nine months ended September 30, 2018, we spent $303.4 million (cash basis) on capital projects and $7.5 million in capital contributions to equity method investees.

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 revolving credit facility, the issuance of debt and equity securities and proceeds from the divestiture of assets or interests in assets.

Preferred Stock Dividends

On May 25, 2018, we paid-in-kind a preferred stock dividend of $4.8 million, which was prorated for the period from January 19, 2018 to March 31, 2018. On August 29, 2018, we paid-in-kind a preferred stock dividend of $6.2 million. On October 31, 2018, we declared a preferred stock dividend to be paid-in-kind of $6.3 million, which will be paid on November 26, 2018. Paid-in-kind dividends increase the Liquidation Preference.

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 Mercuria Energy Trading, Inc., two customers of our Crude Supply and Logistics segment, accounted for more than 10% of our consolidated revenue for the three months ended September 30, 2018, at approximately 23%. Shell Trading (US) Company, a customer of our Crude Supply and Logistics segment, accounted for more than 10% of our consolidated revenue for the nine months ended September 30, 2018, at approximately 26%. The contracts from which our revenues are derived from this customer relate to our crude marketing operations and are for crude oil purchases and sales at market prices. We are not substantially dependent on such contracts and believe that if we were to lose any or all of these contracts, they could be readily replaced under substantially similar terms.

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 revenues.

Off-Balance Sheet Arrangements

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

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 sale locations and purchase and sale timing. We have a risk management function that has responsibility and authority for our Risk Governance Policies, which govern our enterprise-wide risks, including the market risks discussed in this item. Subject to our Risk Governance Policies, 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.

Commodity Price Risk

	Light Sweet Crude Oil Futures (Barrel)	Mont Belvieu (Non-LDH) Spot Propane (Gallon)	Henry Hub Natural Gas Futures (MMBtu)

Low	$42.53	$0.57	$2.56
High/Low Differential	$17.89	$0.44	$0.86

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 the level of other fees generated at our terminalling and storage facilities. Profit from our marketing activities is dependent on

Page 59

Table of Contents

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 $3.7 million increase to gross margin.


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

The above sensitivities 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 September 30, 2018, an increase in the applicable market price or prices for each derivative contract would result in a decrease in our crude oil sales revenues. Likewise, a decrease in the applicable market price or prices for each derivative contract would result in an increase in 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	840 (short)	$	(3,143	)	$	(6,153	)	$	6,153	October 2018

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 September 30, 2018, an increase in these base rates of 1%, above the base rate floors, would increase our interest expense by $3.1 million and $8.0 million for the three months and nine months ended September 30, 2018, respectively. Increases in interest expense due to an increase in interest rates as presented above, would have been partially offset by a reduction of $1.1 million and $3.6 million in interest expense from interest rate swaps, discussed below, for the three months and nine months ended September 30, 2018, respectively.

The average interest rates presented below are based upon rates in effect at September 30, 2018 and December 31, 2017. 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 60

Table of Contents

The following table summarizes our debt obligations:



Liabilities	September 30, 2018	December 31, 2017
Long-term debt - variable rate	$1.3 billion	$948.1 million
Average interest rate	4.84%	4.32%
Long-term debt - fixed rate	$1.4 billion	$1.4 billion
Fixed interest rate	6.16%	6.16%

Debt obligations above include the final payment related to the HFOTCO acquisition, which was made on April 17, 2018.

In conjunction with the HFOTCO acquisition, we acquired HFOTCO’s interest rate swaps. The swaps allow us to limit exposure to interest rate fluctuations. The swaps only apply to a portion of our outstanding debt and provide only partial mitigation of interest rate fluctuations. We have not designated the swaps as hedges, as such changes in the fair value of the swaps are recorded through current period earnings as a component of interest expense. At September 30, 2018, we had interest rate swaps with notional values of $524.3 million. At September 30, 2018, the fair value of our interest rate swaps was $0.2 million which was reported within “other current assets” in our condensed consolidated balance sheet. For the three months ended September 30, 2018 and 2017, we recognized realized and unrealized losses of $0.3 million and $0.6 million related to interest rate swaps, respectively. For the nine months ended September 30, 2018 and 2017, we recognized realized and unrealized gains of $1.5 million and $0.6 million related to interest rate swaps, respectively.

Currency Exchange Risk

The cash flows related to our Canadian operations, and our former U.K. and Mexican 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 foreign 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 nine months ended September 30, 2018, would change operating income by $1.7 million and $11.6 million, respectively.

We enter into foreign currency forwards to purchase Canadian dollars to limit exposure to foreign currency rate fluctuations for capital contributions to our Canadian operations. We have not designated the forwards as hedges, as such changes in the fair value of the forwards are recorded through current period earnings as a component of foreign currency translation gain/loss. At September 30, 2018 and December 31, 2017, we had foreign currency forwards with notional values of $73.9 million and $197.7 million, respectively. At September 30, 2018, the fair value of our foreign currency swaps was $1.0 million, which is reported within “other current liabilities” in our consolidated balance sheet. At December 31, 2017, the fair value of our foreign currency forwards was $2.6 million, which is reported within "other current assets" and “other noncurrent assets” in our condensed consolidated balance sheet. For the three months ended September 30, 2018, we recognized realized and unrealized losses of $1.0 million related to foreign currency forwards. For the nine months ended September 30, 2018, we recognized realized and unrealized losses of $5.5 million related to foreign currency forwards. For the three months and nine months ended September 30, 2017, there were no foreign currency forwards outstanding.

A 1% increase in the USD/CAD foreign exchange rate would lead to a $0.2 million gain and in the event of a 1% decrease in the USD/CAD foreign exchange rate a $2.4 million loss based on the exchange rates at September 30, 2018.
