Basis of Presentation and Principles of Consolidation | Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated balance sheets as of September 30, 2017 , and December 31, 2016 , the unaudited condensed consolidated statements of operations and comprehensive income for the three and nine months ended September 30, 2017 and 2016 , and the unaudited condensed consolidated statements of cash flows for the nine months ended September 30, 2017 and 2016 , have been prepared in accordance with the requirements of the U.S. Securities and Exchange Commission (“SEC”) for interim reporting. Accordingly, certain footnotes and other financial information that are normally required by generally accepted accounting principles in the U.S. (“GAAP”) have been condensed or omitted. The unaudited condensed consolidated balance sheet as of December 31, 2016 has been derived from the Company’s audited financial statements, which are included in its 2016 Annual Report on Form 10-K, filed with the SEC on March 1, 2017 . The unaudited condensed consolidated interim financial statements should be read in conjunction with the Company’s audited consolidated financial statements in its Annual Report on Form 10-K, for the year ended December 31, 2016 . The unaudited condensed consolidated interim financial statements include all adjustments necessary for the fair presentation of the Company's consolidated results of operations, financial position, comprehensive income and cash flows. Results for the interim periods are not necessarily indicative of results to be expected for the full year or any other future periods. All intercompany balances and transactions have been eliminated in the unaudited condensed consolidated interim financial statements. Certain prior period amounts included in the consolidated financial statements have been reclassified to conform to the current period presentation. Adoption of Accounting Pronouncements On March 30, 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-09, Compensation - Stock Compensation: Topic 718: Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”). The Company adopted this pronouncement on a prospective basis effective January 1, 2017. The new guidance simplifies several aspects of how companies account for share-based compensation, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statements of cash flows. ASU 2016-09 was effective for annual periods beginning after December 15, 2016. As a result of the adoption, the Company recognized excess tax benefits in net income of approximately $1.5 million for the nine months ended September 30, 2017 . Also as a result of the adoption, excess tax benefits are included in operating activities rather than classified as a financing activity on the statement of cash flows on a prospective basis. The Company will maintain the current policy of estimating forfeitures expected to occur to determine stock-based compensation expense. On November 20, 2015, the FASB issued ASU No. 2015-17, Income Taxes: Balance Sheet Classification of Deferred Taxes: Topic 740 . ASU 2015-17 was effective for annual periods beginning after December 15, 2016. The Company adopted this pronouncement on a retrospective basis effective January 1, 2017, and reclassified its consolidated balance sheet to present all deferred income tax assets and liabilities as non-current. As a result of this adoption, amounts previously presented as current deferred income tax assets of $4.7 million as of December 31, 2016, were reclassified to net non-current deferred income tax liabilities. Similarly, amounts previously presented as current deferred income tax liabilities of $0.1 million were reclassified to net non-current deferred income tax assets. Recent Accounting Standards or Updates Not Yet Effective On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers: (Topic 606) , to supersede 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 that is expected to be received for those goods or services. This standard is effective for the Company in the first quarter of 2018. The Company will adopt this standard using the modified retrospective method. As a result of its assessment, the Company has identified the following areas that are expected to be relevant to the financial statements: (i) presentation of certain items, including excise taxes on a gross or net basis; (ii) deferral and amortization of contract fulfillment costs; (iii) recognition of contract assets and liabilities for certain contracts that are performed but not completed; and (iv) the timing of recognition of variable consideration received from vendors and paid to customers. Based on work undertaken to date, the new revenue standard is not expected to have a material impact on the amount and timing of revenue recognized in the Company's consolidated financial statements. Once adopted, the Company will provide expanded disclosures regarding the characteristics of its revenue. On February 25, 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , which supersedes existing lease guidance. The new guidance increases transparency by requiring lessees to recognize right-of-use assets and corresponding lease liabilities on the balance sheet. This standard is effective for annual periods beginning after December 15, 2018, although early adoption is permitted. The Company believes the new standard will have a material impact on its consolidated balance sheets. The Company is currently quantifying the impact and evaluating its approach to adopting ASU 2016-02 on its consolidated financial statements. On November 17, 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash . The new guidance requires the statements of cash flows to reconcile the changes in the total of cash, cash equivalents, and restricted cash. As a result, transfers between cash and cash equivalents, and restricted cash and restricted cash equivalents will no longer be presented in the statement of cash flows. ASU 2016-18 is effective for annual periods beginning after December 15, 2017, although early adoption is permitted. As a result of this pronouncement, the Company expects that it will combine its historical movements of restricted cash, with those of non-restricted cash and cash equivalents, as reflected in the Company’s Consolidated Statements of Cash Flows. On January 26, 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment . The new guidance simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. ASU 2017-04 requires goodwill impairment to be measured as the amount by which a reporting unit’s carrying amount exceeds its fair value, not to exceed the carrying amount of its goodwill. ASU 2017-04 requires prospective application and is effective for annual periods beginning after December 15, 2019. The Company believes ASU 2017-04 will amend its methodology for determining any goodwill impairment calculations beginning in 2020. On March 10, 2017, the FASB issued ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Benefit Cost . The new guidance requires employers that sponsor defined benefit pension and other post-retirement plans to present the service cost component of net benefit cost in the same income statement line item as other employee compensation costs arising from services rendered and further requires that only the service cost component will be eligible for capitalization. The other components of the net periodic benefit cost must be presented separately from the line item that includes the service cost component and outside of the income from operations subtotal. ASU 2017-07 is effective for annual periods beginning after December 15, 2017, although early adoption is permitted. The update may result in retrospective re-classification of costs. There will be no impact on consolidated net income. On September 14, 2016, the Board of Directors approved the termination of the Company’s qualified defined-benefit pension plan. The Company expects its pension liabilities will be settled through either lump sum payments or purchased annuities by December 31, 2017. Concentration of Credit Risks Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash investments, accounts receivable and other receivables. The Company places its cash and cash equivalents in short-term instruments with high-quality financial institutions and limits the amount of credit exposure in any one financial instrument. The Company pursues amounts and incentives due from vendors in the normal course of business and is often allowed to deduct these amounts and incentives from payments made to vendors. A credit review is completed for new customers and ongoing credit evaluations of each customer’s financial condition are performed periodically, with reserves maintained for potential credit losses. Credit limits given to customers are based on a risk assessment of their ability to pay and other factors. Accounts receivable are typically not collateralized, but the Company may require prepayments or other guarantees whenever deemed necessary. Murphy U.S.A., the Company's largest customer, accounted for approximately 11.4% , and 12.3% o f the Company’s net sales for the three and nine months ended September 30, 2017 , respectively. No other customers individually accounted for more than 10% of sales for these periods. The Company had two customers during the same periods in 2016 that each accounted for more than 10% of sales. These customers, Murphy U.S.A., and Alimentation Couche-Tard, Inc., together represented approximately 23% of the Company's sales for the three and nine months ended September 30, 2016 . No single customer accounted for 10% or more of the Company’s accounts receivables as of September 30, 2017 or December 31, 2016 . |
