Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Cash and Cash Equivalents Cash and Cash Equivalents consist of all highly liquid investments with maturities of three months or less at the date of purchase. Fair Value of Financial Instruments The carrying amounts of cash and cash equivalents, receivables and payables approximated fair value because of the relatively short maturity of these instruments. See Note 13 “Derivative Financial Instruments” for the fair value of derivative financial instruments. Inventories Inventories consist of oilfield and industrial finished goods. Inventories are stated at the lower of cost or market and using average cost methods. Allowances for excess and obsolete inventories are determined based on the Company’s historical usage of inventory on hand as well as its future expectations. Property, Plant and Equipment Property, plant and equipment are stated at cost. Expenditures for major improvements that extend the lives of property and equipment are capitalized while minor replacements, maintenance and repairs are charged to expense as incurred. Disposals are removed at cost less accumulated depreciation with any resulting gain or loss reflected in the results of operations for the respective period. Depreciation is provided using the straight-line method over the estimated useful lives of individual items. Long-Lived Assets, Including Goodwill and Other Acquired Intangible Assets The Company evaluates the recoverability of property, plant and equipment and amortizable intangible assets for possible impairment whenever events or circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of these assets is measured by a comparison of the carrying amounts to the future undiscounted cash flows the assets are expected to generate. If such review indicates that the carrying amount of property and equipment and intangible assets is not recoverable, the carrying amount of such assets is reduced to fair value. The Company has not recorded any such impairment charge during the years presented. The Company conducts impairment testing for goodwill annually in the fourth quarter of its fiscal year and more frequently, on an interim basis, when an event occurs or circumstances change that indicate that the fair value of a reporting unit may have declined below its carrying value. Events or circumstances which could indicate a probable impairment include, but are not limited to, a significant reduction in worldwide oil and gas prices or drilling; a significant reduction in profitability or cash flow of oil and gas companies or drilling contractors; a significant reduction in worldwide well remediation activity; a significant reduction in capital investment by other oilfield service companies; or a significant increase in worldwide inventories of oil or gas. The Company tests goodwill at the reporting unit level, which is defined as an operating segment or one level below an operating segment that constitutes a business for which financial information is available and is regularly reviewed by management. The Company determined that it has four reporting units for this purpose—United States Energy branches, United States Supply Chain locations, Canada and International. Before testing goodwill, the Company considers whether or not to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount and whether the two-step impairment test is required. The goodwill impairment test is a two-step process. The first step is to identify if a potential impairment exists by comparing the fair value of the reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not considered to have a potential impairment and the second step of the impairment test is not necessary. However if the carrying amount of a reporting unit exceeds its fair value, the second step is performed to determine if goodwill is impaired and to measure the amount of impairment loss to recognize, if any. The second step compares the implied fair value of goodwill with the carrying amount of goodwill. If the implied fair value of goodwill exceeds the carrying amount, then goodwill is not considered impaired. However, if the carrying amount of goodwill exceeds the implied fair value, an impairment loss is recognized in an amount equal to that excess. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination (i.e., the fair value of the reporting unit is allocated to all the assets and liabilities, including any unrecognized intangible assets, as if the reporting unit were acquired in a business combination). When performing goodwill impairment testing, the fair values of reporting units are determined based on valuation techniques using the best available information, including discounted cash flow projections. The Company makes significant assumptions and estimates about the extent and timing of future cash flows, growth rates, and discount rates all of which represent unobservable inputs into valuation methodologies and are classified as level 3 inputs under the fair value hierarchy. In evaluating the reasonableness of the Company’s fair value estimates, the Company considers, among other factors, the relationship between the market capitalization of the Company and the estimated fair value of its reporting units In addition to the recoverability assessment, the Company routinely reviews the remaining estimated useful lives of property, plant and equipment and amortizable intangible assets. If the Company reduces the estimated useful life assumption for any asset, the remaining unamortized balance is amortized or depreciated over the revised estimated useful life. Foreign Currency The functional currency for most of the Company’s foreign operations is the local currency. Certain foreign operations use the U.S. dollar as the functional currency. The cumulative effects of translating the balance sheet accounts from the functional currency into the U.S. dollar at current exchange rates are included in accumulated other comprehensive income (loss). Revenues and expenses are translated at average exchange rates in effect during the period. Accordingly, financial statements of these foreign subsidiaries are remeasured to U.S. dollars for consolidation purposes using current rates of exchange for monetary assets and liabilities and historical rates of exchange for nonmonetary assets and related elements of expense. Revenue and expense elements are remeasured at rates that approximate the rates in effect on the transaction dates. For all operations, gains or losses from remeasuring foreign currency transactions into the reporting currency are included in other income. Net foreign currency transaction losses were $3 million, $2 million and $2 million for the years ending December 31, 2015, 2014 and 2013, respectively, and are included in other income (expense) in the accompanying consolidated statements of operations. Revenue Recognition The Company sells products through store fronts, on-site and eCommerce. The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable, and collectability is reasonably assured. Generally, across every channel, these conditions are met when the product is shipped or picked up by the customer. Revenues are presented net of return allowances and include freight charges billed to customers. Sales tax collected from customers is excluded from revenue in the accompanying consolidated statements of income. Cost of Products Cost of products includes the cost of inventory sold and related items, such as vendor consideration, inventory allowances, amortization of intangibles and inbound and outbound freight. Warehousing, Selling and Administrative Expenses Warehousing, selling and administrative costs include branch location, distribution center and regional expenses (including costs such as compensation, benefits and rent) as well as corporate general selling and administrative expenses. Vendor Consideration The Company receives funds from vendors in the normal course of business, principally as a result of purchase volumes. Generally, these vendor funds do not represent the reimbursement of specific, incremental and identifiable costs incurred by the Company to sell the vendor’s product. Therefore, the Company treats these funds as a reduction of inventory when purchased and once these goods are sold to third parties the associated amount is credited to cost of sales. The Company develops accrual rates for vendor consideration based on the provisions of the arrangements in place, historical trends, purchases and future expectations. Due to the complexity and diversity of the individual vendor agreements, the Company performs analyses and reviews historical trends throughout the year and confirms actual amounts with select vendors to ensure the amounts earned are appropriately recorded. Amounts accrued throughout the year could be impacted if actual purchase volumes differ from projected annual purchase volumes, especially in the case of programs that provide for increased funding when graduated purchase volumes are met. Income Taxes The liability method is used to account for income taxes. Deferred tax assets and liabilities are determined based on differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates that will be in effect when the differences are expected to reverse. Valuation allowances are established when necessary to reduce deferred tax assets to amounts which are more-likely-than-not to be realized. Concentration of Credit Risk The Company grants credit to its customers, which operate primarily in the energy industry. Concentrations of credit risk are limited because the Company has a large number of geographically diverse customers, thus spreading trade credit risk. The Company controls credit risk through credit evaluations, credit limits and monitoring procedures. The Company performs periodic credit evaluations of its customers’ financial condition and generally does not require collateral, but may require letters of credit for certain international sales. Credit losses are provided for in the financial statements. Allowances for doubtful accounts are determined based on a continuous process of assessing the Company’s portfolio on an individual customer basis taking into account current market conditions and trends. This process consists of a thorough review of historical collection experience, current aging status of the customer accounts, and financial condition of the Company’s customers. Based on a review of these factors, the Company will establish or adjust allowances for specific customers. Balances that remain outstanding after the Company has used reasonable collection efforts are written off through a charge to the valuation allowance and a credit to receivables. No single customer represents more than 10% of the Company’s revenue. The Company’s top 20 customers in aggregate represent approximately one-third of the Company’s revenue. Stock-Based Compensation Compensation expense for the Company’s stock-based compensation plans is measured using the fair value method required by ASC Topic 718 “Compensation—Stock Compensation” (“ASC Topic 718”). Under this guidance the fair value of stock option grants and restricted stock is amortized to expense using the straight-line method over the shorter of the vesting period or the remaining employee service period. The Company provides compensation benefits to employees and non-employee directors under share-based payment arrangements. The Company settles stock option exercises with newly issued shares of stock. Environmental Liabilities When environmental assessments or remediations are probable and the costs can be reasonably estimated, remediation liabilities are recorded on an undiscounted basis and are adjusted as further information develops or circumstances change. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect reported and contingent amounts of assets and liabilities as of the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Contingencies The Company accrues for costs relating to litigation claims and other contingent matters, when such liabilities become probable and reasonably estimable. Such estimates may be based on advice from third parties or on management’s judgment, as appropriate. Revisions to contingent liabilities are reflected in income in the period in which different facts or information become known or circumstances change that affect the Company’s previous judgments with respect to the likelihood or amount of loss. Amounts paid upon the ultimate resolution of contingent liabilities may be materially different from previous estimates and could require adjustments to the estimated reserves to be recognized in the period such new information becomes known. In circumstances where the most likely outcome of a contingency can be reasonably estimated, the Company accrues a liability for that amount. Where the most likely outcome cannot be estimated, a range of potential losses is established and if no one amount in that range is more likely than others, the low end of the range is accrued.
