2. Basis of Presentation and Significant Accounting Policies

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In management's opinion, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and six months ended June 30, 2017, are not necessarily indicative of the results that may be expected for the year ending December 31, 2017, or for any other period. We have not reported comprehensive income due to the absence of items of other comprehensive income or loss during the periods presented. The accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2016. The condensed consolidated financial statements do not reflect the push-down accounting of the purchase price adjustments resulting from the Andeavor Acquisition.

Restricted Cash

Restricted cash reported in our Condensed Consolidated Balance Sheet at June 30, 2017 relates to net proceeds from the sale of our lubricant operations located in Arizona and Nevada during the second quarter of 2017. This cash is restricted through June 30, 2018 and must be used to reinvest in assets used in our business or as a prepayment of debt.

Financial Instruments and Fair Value

Financial instruments that potentially subject us to concentrations of credit risk consist of accounts receivable. We believe that our credit risk is minimized as a result of the credit quality of our customer base. The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities, which we consider Level 1 assets, approximated their fair values at June 30, 2017 and December 31, 2016, due to their short-term maturities. The carrying amount of our debt is the amount reflected in the Condensed Consolidated Balance Sheets, including the current portion. The fair value of the debt was determined based on prices from recent trade activity and is categorized in Level 2 of the fair value hierarchy. See Note 10, Debt, for additional information.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Recent Accounting Pronouncements

Effective January 1, 2017, we adopted the accounting and reporting requirements included in the Accounting Standards Codification ("ASC") for employee share-based payment accounting. We have applied the new standard prospectively, except for the cash flow considerations, which we applied retrospectively. The adoption of these revised standards was not material to our financial position or results of operations. The presentation of our Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2016, has been retrospectively adjusted to include payments of $0.5 million for tax withholdings for stock-based compensation in net cash used in financing activities that was previously reported in net cash provided by operating activities as a change in accounts payable and accrued liabilities.

Accounting Standards Update 2017-03 addresses the disclosure requirements in regards to the impact that recently issued accounting standards will have on the financial statements of a registrant when such standards are adopted in a future period. The specific impact of this guidance will be determined by the respective changes in GAAP.

From time to time, new accounting pronouncements are issued by various standard setting bodies that may have an impact on our accounting and reporting. We are currently evaluating the effect that certain of these new accounting requirements may have on our accounting and related reporting and disclosures in our condensed consolidated financial statements.

•

Recognition and reporting of revenues - the requirements were amended to remove inconsistencies in revenue requirements and to provide a more complete framework for addressing revenue issues across a broad range of industries and transaction types. The revised standard’s core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The revised standard also addresses principal versus agent considerations and indicators related to transfer of control over specified goods. These provisions are effective January 1, 2018, and can be adopted using either a full retrospective approach or a modified approach, with early adoption permitted for periods beginning after December 15, 2016, and interim periods thereafter.

We have been evaluating and continue to evaluate the provisions of this standard and its impact on our business processes, business and accounting systems, and financial statements and related disclosures. A multi-disciplined implementation team has gained an understanding of the standard’s revenue recognition model, is reviewing and documenting our contracts, and is analyzing whether enhancements are needed to our business and accounting systems. Thus far in our review and analysis, we have not identified any material differences in our existing revenue recognition methods that would require modification under the new standard. We expect to complete this phase of our implementation plan within the next several months after which we will implement any changes to existing business processes and systems to accommodate the new standard. We will adopt this standard as of January 1, 2018. We preliminarily expect to transition to the new standard under the modified retrospective transition method, whereby a cumulative effect adjustment is recognized upon adoption and the guidance is applied prospectively.

•

Lease accounting - the requirements were amended with regard to recognizing lease assets and lease liabilities on the balance sheet and disclosing information about leasing arrangements. The core principle is that a lessee should recognize the assets and liabilities that arise from leases. These provisions are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. We have been evaluating and continue to evaluate the provisions of this standard and its impact on our business processes, business and accounting systems, and financial statements and related disclosures.


•	Cash flow statement - the requirements address certain classification issues related to the statement of cash flows. These provisions are effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Early adoption is permitted in any interim or annual period.

•

Business combinations - the requirements clarify the definition of a business and provide a framework that gives entities a basis for making reasonable judgments about whether a transaction involves an asset or a business. This guidance is effective in annual periods beginning after December 15, 2017, including interim periods therein. It must be applied prospectively on or after the effective date with early adoption permitted subject to certain requirements, and no disclosures for a change in accounting principle are required at transition.
