Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Principles of Consolidation The consolidated financial statements include the accounts of the Company, our wholly-owned subsidiaries and our majority-owned subsidiaries, in which we hold a controlling interest. All intercompany accounts and transactions are eliminated in consolidation. We use the equity method to account for investments in affiliated companies that are 20% to 50% owned, and in cases where we do not hold a controlling voting interest and do not direct the matters that most significantly impact the investee’s operations. We own an 80% interest in Olin Luotong (GZ) Corporation (“Olin Luotong Metals” or “OLM”), based in China, and Olin Luotong Metals’ financial information is consolidated herein, with the net results attributable to the 20% noncontrolling interest reflected in the accompanying consolidated financial statements. Use of Estimates and Assumptions The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“US 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. In addition, it requires management to make estimates and assumptions that affect the reported amount of net sales and expenses during the reporting period. Actual amounts could differ from those estimates. Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable primarily consists of trade receivables for amounts billed to customers for products sold and other receivables. The determination of collectibility of our accounts receivable requires management to make frequent judgments and estimates in order to determine the appropriate allowance needed for doubtful accounts. In circumstances where we are aware of a customer’s inability to meet its financial obligations (e.g., bankruptcy filings or substantial down-grading of credit ratings), we record an allowance for bad debts equal to the amount we believe is not collectible. For all other customers, we recognize allowances for bad debts based on historical collection experience. If circumstances change (e.g., greater than expected defaults or an unexpected material change in a major customer’s ability to meet its financial obligations), the estimate of the allowance could change by a material amount. Accounts are written off once deemed to be uncollectible. Inventories Inventories include costs attributable to direct labor and manufacturing overhead but are primarily comprised of metal costs. The metals component of inventories that is valued on a last-in, first-out (“LIFO”) basis comprised approximately 70% of total inventory at both December 31, 2016 and 2015 . Other manufactured inventories, including the direct labor and manufacturing overhead components and certain non-U.S. inventories, are valued on a first-in, first-out (“FIFO”) basis. In addition to the cost of material, finished goods inventory includes costs for depreciation, utilities, consumable production supplies, maintenance, production wages and transportation. Inventories are stated at the lower of cost or market. The market price of metals used in production and related scrap is subject to volatility. We evaluate the need to record adjustments for inventory on a regular basis. During periods when open market prices decline below carrying value, we record a provision to reduce the carrying value of inventory. Additionally, we record an estimate for slow moving and obsolete inventory based upon product knowledge, physical inventory observation, future demand, market conditions and an aging analysis of the inventory on hand. Our policy is to evaluate all inventories including raw material, work-in-process, finished goods, and spare parts. Inventory in excess of estimated usage requirements is written down to its estimated net realizable value. Property, Plant and Equipment Property, plant and equipment are recorded at cost. Depreciation of property, plant and equipment, which includes the depreciation of assets under capital leases, is computed using the straight-line method based on the estimated useful lives of the assets as they are placed into service. Property, plant and equipment are generally depreciated over the useful lives, which are detailed in the notes to the accompanying consolidated financial statements. Depreciation expense is recorded in cost of sales or selling, general and administrative costs depending on the nature and use of the underlying asset. Expenditures for repairs and maintenance are expensed as incurred. Expenditures which improve an asset or extend its estimated useful life are capitalized. Interest costs related to the construction of qualifying assets are capitalized as part of the construction costs. When assets are retired or otherwise disposed of, the related cost and accumulated depreciation are removed from the accounts and any gain or loss is included in the accompanying consolidated statements of operations. We review property, plant and equipment for impairment when a change in events or circumstances indicates that the carrying value of the assets may not be recoverable. We determine the fair value of our asset group through various valuation techniques, including discounted cash flow models, quoted market values and third-party independent appraisals, as considered necessary. Acquisitions and Goodwill All acquisitions are accounted for using the acquisition method as prescribed by ASC 805, Business Combinations . The purchase price paid is allocated to the assets acquired and liabilities assumed based on their estimated fair values. Any excess purchase price over the fair value of the net assets acquired is recorded as goodwill. Goodwill is not amortized but is tested for impairment annually and whenever events or changes in circumstances indicate that impairment may have occurred. Management performs its annual goodwill impairment test as of October 31 and monitors for interim triggering events on an ongoing basis. We utilized the qualitative goodwill evaluation model for our annual goodwill impairment test conducted as of October 31, 2016 . Based on the results of that qualitative assessment, we believe it was more likely than not that the fair value of the reporting units exceeded their carrying values as of October 31, 2016 , indicating no impairment of goodwill. Intangible Assets Definite-lived intangible assets are recorded at fair value under the purchase method of accounting as of the respective acquisition dates and are amortized using the straight-line method over the estimated useful lives of the assets. Amortization expense related to intangible assets is reflected in selling, general and administrative expenses. Identifiable definite-lived intangible assets are reviewed for impairment whenever events or circumstances indicate that the carrying value may not be recoverable. We do not have any indefinite-lived intangible assets as of December 31, 2016 and 2015 . Accumulated amortization was $1.3 million and $1.2 million as of December 31, 2016 and 2015 , respectively. Annual amortization expense is expected to be $0.1 million for each of the next four years. Deferred Financing Fees Deferred financing fees incurred in connection with the issuance of debt are amortized as non-cash interest expense over the terms of the debt agreements. The unamortized balances of deferred financing fees incurred in connection with the issuance of our long-term debt facilities are presented in noncurrent portion of debt in the consolidated balance sheets and are amortized using the effective interest method over the term of the debt facility. The unamortized balances of deferred financing fees incurred in connection with the issuance of our asset based loan facility are presented in other noncurrent assets in the consolidated balance sheets and are amortized on a straight-line basis over the term of the facility. Derivative Contracts Our operating activities expose us to a variety of market risks, including risks related to the effects of commodity prices and interest rates. We monitor and manage these financial exposures as an integral part of our overall risk-management program. We do not enter into derivative contracts for speculation purposes where the objective is to generate profits. We have not applied hedge accounting to our derivative contracts in 2016 , 2015 or 2014 . We include the fair value of the derivative contracts as assets or liabilities in our consolidated balance sheet and recognize all amounts paid and received and changes in fair value of derivative contracts, including unrealized gains and losses, as adjustments to income in the accompanying consolidated statements of operations. Treasury Stock Our Board of Directors has not enacted a program to purchase our common stock in the open market. However, management periodically purchases shares of our common stock from employees as part of equity-based compensation programs. These repurchases are reflected at cost within treasury stock in the consolidated balance sheets. Share-Based Compensation We have one share-based compensation plan, which is described in Note 17 , “ Share-based Compensation .” Pursuant to this plan, we have granted non-qualified options, restricted stock and performance-based shares to certain employees and members of our management and our Board of Directors. See Note 17 , “ Share-based Compensation ” for further detail. Revenue Recognition We recognize revenue when title and risk of loss are transferred to customers, which is generally the date products are shipped. Estimates for future rebates on certain product lines and product returns are recognized in the period in which the revenue is recorded. Such rebates were not material for 2016 , 2015 or 2014 . Billings to customers for shipping costs are included in net sales and the cost of shipping product to those customers is reflected in cost of sales in the accompanying consolidated statements of operations. In connection with sales of unprocessed metal to toll customers, we record deferred expense and deferred revenue in prepaid expenses and other current assets and in accrued liabilities, respectively, in the consolidated balance sheets. The unprocessed metal is held for the account of the toll customers at our premises, together with our other inventory. Deferred expense represents the deferral of cost of sales and deferred revenue represents the deferral of sales revenue, in each case, associated with such sales of unprocessed metal to toll customers. We defer the expense for such unprocessed metal sales (and the corresponding revenue from sales of unprocessed metal) to toll customers until the finished product has been manufactured and shipped, at which time risk of loss and title passes to the customer. Provision for Income Taxes The provision for income taxes is determined using the asset and liability approach. The current and deferred tax consequences are measured by applying the provisions of enacted tax laws to determine the amount of taxes payable currently or in future years. Deferred income taxes are provided for temporary differences between the income tax basis of assets and liabilities and their carrying amounts for financial reporting purposes. A valuation allowance is recorded to reduce deferred tax assets when management determines it is “more likely than not” that some portion or all of the deferred tax assets will not be realized. Foreign Currency Translation The financial statements of foreign subsidiaries are translated into United States dollars in accordance with ASC 830, Foreign Currency Matters . The functional currency of our foreign subsidiaries is the local currency. The consolidated statements of foreign operations are translated at weighted-average exchange rates for the periods. Assets and liabilities are translated at period-end exchange rates and equity transactions are translated at historical rates. Gains and losses resulting from the translation adjustment are reported as a component of other comprehensive income (loss). The income tax effect of currency translation adjustments related to foreign subsidiaries and joint ventures that are not considered indefinitely reinvested are recorded as a component of deferred taxes with an offset to other comprehensive income (loss). Concentrations of Credit Risk and Certain Other Exposures We sell and distribute our products to a wide range of companies primarily in the building and housing, munitions, automotive, transportation, coinage, electronics / electrical components and industrial machinery and equipment markets. We perform ongoing credit evaluations of our customers and generally do not require collateral. In 2015 , sales to one major customer amounted to 12% of net sales. In 2016 and 2014 , no customer represented 10% or more of consolidated net sales. We use various strategies to minimize the impact of changes in the base metal prices between the date of order from a customer and the date of sale to a customer. Generally, we price a forward replacement purchase of an equivalent amount of copper and other metals under flexible pricing arrangements with our suppliers, at the same time we determine the forward selling price of finished products to our customers. We have various sources of raw materials and are not materially dependent on any one supplier. As of December 31, 2016 , approximately 61% of our employees at various sites were members of unions. Generally, our various agreements with unions in the United States have contractual terms which range from 1 to 5 years. Since our establishment in November 2007, we have not experienced any work stoppages at any of our facilities. We are required to make contributions to the IAM National Pension Plan (“IAM Plan”), a multi-employer pension plan that covers certain of our union employees. Our obligations may be impacted by the funded status of the plan, the plan’s investment performance, changes in the participant demographics, financial stability of contributing employers and changes in actuarial assumptions. In addition, if a participating employer becomes insolvent and ceases to contribute to a multiemployer plan, the unfunded obligation of the plan will be borne by the remaining participating employers. Under current law, an employer that withdraws or partially withdraws from a multi-employer pension plan may incur withdrawal liability to the plan. Given that the IAM Plan is over funded, many other participating employers are much larger than us and there are a large number of participating employers in the plan, we do not view this to be a significant risk. Self-Insurance Programs We are self-insured up to a retention amount for workers’ compensation claims and benefits paid under employee health care programs. Accruals for employee health care are primarily based on estimated undiscounted cost of claims, which includes incurred but not reported claims. Accruals for workers’ compensation benefits and related expenses for claims are estimated, in part, by considering historical claims experience and undiscounted claims estimates provided by insurance carriers, third-party administrators and actuaries. Self-insurance accruals are deemed to be sufficient to cover outstanding claims, including those incurred but not reported as of the estimation date. Environmental Reserves and Environmental Expenses We recognize an environmental liability when it is probable the liability exists and the amount is reasonably estimable. We estimate the duration and extent of our remediation obligations based upon internal analyses of clean-up costs, ongoing monitoring costs and estimated legal fees, communications with regulatory agencies and changes in environmental law. If we were to determine that our estimates of the duration or extent of environmental obligations were no longer accurate, we would adjust our environmental liabilities accordingly in the period that such determination is made. Estimated future expenditures for environmental remediation are not discounted to their present value. Accrued environmental liabilities are not reduced by potential insurance reimbursements. Environmental expenses that relate to ongoing operations are included as a component of cost of sales in the accompanying consolidated statement of operations. Recently Issued and Recently Adopted Accounting Pronouncements In August 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). The amendments in ASU 2016-15 address the presentation and classification for eight specific issues in the statement of cash flows, with the objective of reducing diversity in practice. The new standard provides specific guidance for: • Debt prepayment or debt extinguishment costs; • Settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; • Contingent consideration payments made after a business combination; • Proceeds from the settlement of insurance claims; • Proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; • Distributions received from equity method investees; • Beneficial interests in securitization transactions; and • Separately identifiable cash flows and application of the predominance principle. The required transition method will use a full retrospective approach for all periods presented with limited exceptions. The standard update is effective for fiscal years beginning after December 15, 2017 and interim periods within those years. Early adoption is permitted in any interim or annual period. The new standard addresses the classification of debt extinguishment costs, which we have reported in both the current and prior years. The new guidance is consistent with our presentation in the statement of cash flows. Thus, our early adoption of this standard during 2016 did not have an impact on our consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-9, Compensation-Stock Compensation (Topic 718) (“ASU 2016-9”). ASU 2016-9 simplifies various aspects of the accounting for share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities, classification on the statement of cash flows and forfeiture rate calculations. The provisions of ASU 2016-9 are effective for fiscal years, and interim reporting periods within those fiscal years, beginning after December 15, 2016, with early adoption permitted. We do not believe that the adoption of this standard will have a material impact on our consolidated financial statements, however, the impact is affected by future transactions and changes in our stock price. In February 2016, the FASB issued ASU No. 2016-2, Leases (Topic 842) (“ASU 2016-2”). ASU 2016-2 sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease effectively finances a purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method (finance lease) or on a straight line basis over the term of the lease (operating lease). A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. ASU 2016-2 supersedes the existing guidance on accounting for leases in “ Leases (Topic 840).” The provisions of ASU 2016-2 are effective for fiscal years, and interim reporting periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted and the provisions are to be applied using a modified retrospective approach. We are in the process of evaluating the impact of adoption on our consolidated financial statements. In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments (“ASU 2015-16”). ASU 2015-16 requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. ASU 2015-16 is effective for fiscal years, and interim reporting periods within those fiscal years, beginning after December 15, 2015. The adoption of this standard did not have a material impact on our consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-9, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-9”). The guidance provides companies with a single model for use in accounting for revenue arising from contracts with customers and supersedes current revenue recognition guidance, including industry-specific revenue guidance. The FASB subsequently issued ASU No. 2015-14, Revenue From Contracts With Customers (Topic 606): Deferral of the Effective Date (“ASU 2015-14”), ASU No. 2016-8, Revenue from Contracts with Customers - Principal versus Agent Considerations (Reporting Revenue Gross versus Net) (Topic 606) (“ASU 2016-8”), ASU No. 2016-10, Identifying Performance Obligations and Licensing (Topic 606), ASU No. 2016-12, Narrow-Scope Improvements and Practical Expedients (Topic 606) and ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers , which further clarify aspects of the initial ASU. The guidance is effective for fiscal years, and interim reporting periods within those fiscal years, beginning after December 15, 2017. The revenue recognition guidance permits companies to either apply the requirements retrospectively to all prior periods presented, or apply the requirements in the year of adoption, through a cumulative adjustment. We are in the process of evaluating the impact of adoption on our consolidated financial statements. |
