Summary of Significant Accounting Policies [Text Block] | Summary of Significant Accounting Policies General The Company is a leading global supplier of lightweighting and NVH solutions to the automotive, commercial vehicle and industrial markets. The Company offers one of the broadest portfolio of lightweighting solutions to the automotive, commercial vehicle and industrial markets, capable of delivering solutions in aluminum, magnesium, steel and steel alloys. Shiloh delivers these solutions through the design and manufacturing of its BlankLight, ™ CastLight ™ and StampLight ™ brands. Shiloh delivers solutions in body, chassis and powertrain systems to original equipment manufacturers ("OEMs") and several "Tier 1" suppliers to the OEM's. The Company has twenty-eight wholly-owned subsidiaries at locations in Asia, Europe and North America as well as a 55% ownership of a joint venture in China with no operating activity for the fiscal year ended October 31, 2015 . MTD Holdings Inc. (the parent of MTD Products Inc.) and the MTD Products Inc. Master Employee Benefit Trust, a trust fund established and sponsored by MTD Products Inc. owned approximately 48.5% of the Company's outstanding shares of Common Stock as of October 31, 2015 , making MTD Holdings Inc. and MTD Products Inc. related parties of the Company. Principles of Consolidation The consolidated financial statements include the accounts of Shiloh Industries, Inc., all wholly-owned subsidiaries and the joint venture in China. All significant intercompany transactions have been eliminated. Revenue Recognition The Company recognizes revenue from the sales of products when there is evidence of a sales agreement, the delivery of goods has occurred, the sales price is fixed or determinable and collectability of revenue is reasonably assured. The Company records revenues upon shipment of product to customers and transfer of title under standard commercial terms. Price adjustments, including those arising from resolution of quality issues, price and quantity discrepancies, surcharges for fuel and/or steel and other commercial issues, are recognized in the period when management believes that such amounts become probable, based on management’s estimates. The Company enters into tooling contracts with customers in the development of molds, dies and tools (collectively, "tooling")to be sold to such customers. Revenue is recognized when the tooling is delivered and accepted by the customer. The Company also may progress bill for certain tooling being constructed for its customers. These billings are recorded as progress billings (a reduction of the associated tooling costs) until the appropriate revenue recognition criteria have been met. The tooling contracts are separate arrangements between the Company and customer and are recorded on a gross or net basis in accordance with current applicable revenue recognition accounting literature. Allowance for Doubtful Accounts The Company evaluates the collectability of accounts receivable based on several factors. In circumstances when the Company is aware of a specific customer’s inability to meet its financial obligations, a specific allowance for doubtful accounts is recorded against amounts due to reduce the net recognized receivable to the amount the Company reasonably believes will be collected. Additionally, a general allowance for doubtful accounts is estimated based on historical write-offs and the current financial condition of customers. The financial condition of the Company’s customers is dependent on, among other things, the general economic environment, which may substantially change. This variability may affect the recoverability of amounts due to the Company from its customers. The Company carefully assesses its risk with each of its customers and considers compliance with terms and conditions, aging of the customer accounts, intelligence learned through contact with customer representatives and its right of offset of net account receivable / account payable position with customers, if applicable, in establishing the allowance. Shipping and Handling Costs The Company classifies all amounts billed to a customer in a sales transaction related to shipping and handling as revenue and the costs incurred by the Company for shipping and handling are classified as costs of sales. Inventories Inventories are valued at the lower of cost or market, using the first-in first-out ("FIFO") method. Pre-production and development costs The Company enters into contractual agreements with certain customers to develop molds, dies and tools (collectively, "tooling"). All such tooling contracts relate to parts that the Company will supply to customers under supply agreements. Tooling costs are capitalized in prepaid expenses and other assets determined by the fact that tooling contracts are separate from standard production contracts. The classification in prepaid or other assets is based upon the period of reimbursement from customer as either short-term or long-term. Property, Plant and Equipment Property, plant and equipment are stated at cost or at fair market value for plant, property and equipment acquired through acquisitions. Expenditures for maintenance, repairs and renewals are charged to expense as incurred, while major improvements are capitalized. The cost of these improvements is depreciated over their estimated useful lives. Useful lives range from three to twelve years for furniture and fixtures and machinery and equipment, or if the assets are dedicated to a customer program, over the estimated life of that program, ten to twenty years for land improvements and twenty to forty years for buildings and their related improvements. Depreciation is computed using the straight-line method for financial reporting purposes and accelerated methods for income tax purposes. When assets are retired or otherwise disposed, the related cost and accumulated depreciation are removed from the accounts, and any gain or loss on the disposition is included in the earnings for the current period. Employee Benefit Plans The Company accrues the cost of U.S. defined benefit pension plans, which are frozen in accordance with Statement of Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 715 "Compensation - Retirement Benefits." The plans are funded based on the requirements and limitations of the Employee Retirement Income Security Act of 1974. As of October 31, 2015 , approximately 95% of employees of the Company participated in discretionary profit sharing plans administered by the Company. The Company also provides postretirement benefits to 16 former employees. Stock-Based Compensation The Company records compensation expense for the fair value of nonvested stock option awards and restricted stock awards over the remaining vesting period. The Company has elected to use the simplified method to calculate the expected term of the stock options outstanding at five to six years and has utilized historical weighted average volatility. The Company determines the volatility and risk-free rate assumptions used in computing the fair value using the Black-Scholes option-pricing model, in consultation with an outside third party. The expected term for the restricted stock award is between three months to four years. Income Taxes The Company utilizes the asset and liability method in accounting for income taxes. Income tax expense includes U.S. and foreign income taxes minus tax credits and other incentives that will reduce tax expense in the year they are claimed. Deferred taxes are recognized at currently enacted tax rates for temporary differences between the financial accounting and income tax basis of assets and liabilities and operating losses and tax credit carryforwards. Valuation allowances are recorded to reduce net deferred tax assets to the amount that is more likely than not to be realized. The Company assesses both positive and negative evidence when measuring the need for a valuation allowance. Evidence typically assessed includes the operating results for the most recent three-year period and, to a lesser extent because of inherent uncertainty, the expectations of future profitability, available tax planning strategies, the time period over which the temporary differences will reverse and taxable income in prior carryback years if carryback is permitted under the tax law. The calculation of the Company's tax liabilities also involves dealing with uncertainties in the application of complex tax laws and regulations in a multitude of jurisdictions across our global operations. The Company recognizes liabilities for uncertain income tax positions based on the Company's estimate of whether, and the extent to which, additional taxes will be required. The Company reports interest and penalties related to uncertain income tax positions as income taxes. U.S. income taxes and foreign withholding taxes are not provided on undistributed earnings of foreign subsidiaries because it is expected such earnings will be permanently reinvested in the operations of such subsidiaries or to pay down third party European debt. As of October 31, 2015 , there was approximately $3,384 of undistributed foreign subsidiary earnings. The income tax liability that would result had such earnings been repatriated is estimated at $1,184 . Impairment of Long-Lived and Intangible Assets The Company evaluates the recoverability of long-lived assets and the related estimated remaining lives whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Events or changes in circumstances that could cause an impairment include significant underperformance relative to the historical or projected future operating results, significant changes in the manner of the use of the assets or the strategy for the overall business or significant negative industry or economic trends. The Company records an impairment or change in useful life whenever events or changes in circumstances indicate that the carrying amount of long-lived assets may not be recoverable or the useful life has changed. Goodwill. Goodwill, which represents the excess cost over the fair value of the net assets of businesses acquired, was $28,843 as of October 31, 2015 , or 4.3% of its total assets, and $30,887 as of October 31, 2014 , or 4.9% of its total assets. In accordance with Accounting Standards Codification ("ASC") 350, Intangibles-Goodwill and Other, the Company assesses goodwill for impairment on an annual basis. Such assessment can be done on a qualitative or quantitative basis. To qualitatively assess the likelihood of goodwill being impaired, the Company considers the following factors at the reporting unit level: the excess of fair value over carrying value as of the last impairment test, the length of time since the last fair value measurement, the carrying value, market and industry metrics, actual performance compared to forecasted performance, and its current outlook on the business. If the qualitative assessment indicated it is more likely than not that goodwill is impaired, the Company will perform quantitative impairment testing at the reporting unit level. To quantitatively test goodwill for impairment, the Company estimates the fair value and compares the fair value to the carrying value. If the carrying value exceeds the fair value, then a possible impairment of goodwill may exist and further evaluation is required. Fair values are based on the cash flow projected in the strategic plans and long-range planning forecasts, discounted at a risk-adjusted rate of return. Revenue growth rates included in the plans are generally based on industry specific data and known awarded business. The projected profit margin assumptions included in the plans are based on current cost structure and anticipated productivity improvements. If different assumptions were used in the plans, the related cash flows used in measuring fair value could be different and impairment of goodwill might be required to be recorded. Comprehensive Income (Loss) Comprehensive income (loss) is defined as net income (loss) less changes in stockholders' equity from non-owner sources which, for the Company in the periods presented, consists of foreign currency translations, interest rate swaps, marketable securities and pension related liability adjustments. Statement of Cash Flows Information Cash and cash equivalents include checking accounts and all highly liquid investments with an original maturity of three months or less. A substantial majority of the Company’s cash and cash equivalent bank balances exceeded federally insured limits at October 31, 2015 . Cash in foreign subsidiaries totaled $13,907 and $11,921 at October 31, 2015 and October 31, 2014 , respectively. Concentration of Risk The Company sells products to customers primarily in the automotive, commercial vehicle and industrial markets. Financial instruments, which potentially subject the Company to concentration of credit risk, are primarily accounts receivable. The Company performs on-going credit evaluations of its customers' financial condition. The allowance for non-collection of accounts receivable is based on the expected collectability of all accounts receivable. Losses have historically been within management's expectations. The Company does not have financial instruments with off-balance sheet risk. Refer to Note 19-Business Segment Information for discussion of concentration of revenues. The Company believes that the concentration of credit risk in its trade receivables is substantially mitigated by the Company's ongoing credit evaluation process and relatively short collection terms. The Company does not generally require collateral from customers. The Company establishes an allowance for doubtful accounts based upon factors surrounding the credit risk of specific customers, historical trends and other information. Fair Value of Financial Instruments The carrying amounts of cash and cash equivalents, trade receivables and payables approximate fair value because of the short maturity of those instruments. The carrying value of the Company's debt and derivative instruments are considered to approximate the fair value of these instruments based on the borrowing rates currently available to the Company for loans with similar terms and maturities. Derivative Financial Instruments The Company uses interest rate swaps to manage volatility of underlying exposures. The Company recognizes all of its derivative instruments as either assets or liabilities at fair value. The accounting for changes in the fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated, and is effective, as a hedge and further, on the type of hedging relationship. For those derivative instruments that are designated and qualify as hedging instruments, a company must designate the instrument, based upon the exposure being hedged, as a fair value hedge, cash flow hedge or a hedge of a net investment in a foreign operation. Gains and losses related to a hedge are either recognized in income immediately to offset the gain or loss on the hedged item or are deferred and reported as a component of Comprehensive Income (Loss) and subsequently recognized in earnings when the hedged item affects earnings. The change in fair value of the ineffective portion of a hedging instrument, determined using the hypothetical derivative method, is recognized in earnings immediately. The gain or loss related to financial instruments that are not designated as hedges are recognized immediately in earnings. Cash flows related to hedging activities are included in the operating section of the consolidated statements of cash flows. The Company does not hold or issue derivative financial instruments for trading or speculative purposes. The Company’s objective for holding derivatives is to minimize risk using the most effective and cost-efficient methods available. Foreign Currency Translation Two of the Company's Mexican subsidiaries (Shiloh De Mexico S.A. DE C.V. and Shiloh International, S.A. DE C.V.), the Company's Netherlands and Swedish holding companies, and all the Company's U.S. subsidiaries have the U.S. dollar as their functional currency. For all other entities, the functional currency is their respective local currency. The translation from the applicable foreign currencies to U.S. dollars is performed for balance sheet accounts using exchange rates in effect at the balance sheet date and for revenue and expense accounts using a weighted average exchange rate for the period. The resulting translation adjustments are recorded as a component of Other Comprehensive Income ("OCI"). The Company engages in foreign currency denominated transactions with customers and suppliers, as well as between subsidiaries with different functional currencies. Gains and losses resulting from foreign currency transactions are recognized in net income (loss) in the consolidated statements of income. Guarantees The Company has certain indemnification clauses within its Credit Agreement (as defined below) and certain lease agreements that are considered to be guarantees within the scope of FASB ASC Topic 460, "Guarantees." The Company does not consider these guarantees to be probable, and the Company cannot estimate their maximum exposure. Additionally, the Company's exposure to warranty-related obligations is not material. Accounting Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America 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. On an ongoing basis, management reviews its estimates based upon current available information. Actual results could differ from those estimates. Prior Year Reclassification Certain prior year amounts have been reclassified to conform with current year presentation. In the current year, the Company reclassified certain prior year amounts related to tooling from inventory to prepaid expenses to conform with the current year presentation. Such reclassification is reflected in the consolidated financial statements and the related notes thereto, and resulted in a reclassification of $29,460 from inventory to prepaid expenses as of October 31, 2014 . Other New Accounting Standards In January 2016, Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-01, "Recognition and Measurement of Financial Assets and Financial Liabilities." ASU 2016-01 requires equity investments to be measured at fair value with changes in fair value recognized in net income; simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment;Eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet; requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments; requires separate presentation of financial assets and financial liabilities by measurement category and form of financial assets on the balance sheet or the accompanying notes to the financial statements and clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. ASU 2016-01 is effective for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company is currently evaluating the impact that ASU 2016-01 will have on its statement of financial position or financial statement disclosures. In November 2015, FASB issued ASU 2015-17, "Balance Sheet Classification of Deferred Taxes." ASU 2015-17 requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. ASU 2015-17 is effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The Company is currently evaluating the impact that ASU 2015-17 will have on its statement of financial position or financial statement disclosures. In September 2015, FASB issued Accounting Standards Update ("ASU") 2015-16, "Business Combinations." ASU 2015-16 simplifies the accounting for measurement-period adjustments by requiring adjustments to provisional amounts in a business combination to be recognized in the reporting period in which the adjustment amounts are determined and eliminates the requirement to retrospectively account for those adjustments. ASU 2015-16 requires an entity to present separately on the face of the income statement or disclose in the notes the amount recorded in current-period earnings that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU 2015-16 is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The Company does not expect ASU 2015-16 will have a material impact on its statement of financial position or financial statement disclosures. In July 2015, the FASB issued ASU 2015-11, "Inventory." ASU 2015-11 simplifies the measurement of inventory by requiring inventory to be measured at the lower of cost and net realizable value. ASU 2015-11 is effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The Company does not expect ASU 2015-11 will have a material impact on its statement of financial position or financial statement disclosures. In June 2015, the FASB issued ASU 2015-10, "Technical Corrections and Improvements." ASU 2015-10 amends a wide range of topics in the existing codification. ASU 2015-10 is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years, although early adoption is permitted, including adoption in an interim period. The Company does not expect ASU 2015-10 will have a material impact on its statement of financial position or financial statement disclosures. In April 2015, the FASB issued ASU 2015-03, "Interest - Imputation of Interest." ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in the ASU. ASU 2015-03 was amended in June 2015 to note that there are no requirements in the presentation or subsequent measurement of the debt issuance costs associated with line-of-credit arrangements. ASU 2015-03 is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The Company does not expect ASU 2015-03 will have a material impact on its statement of financial position or financial statement disclosures. In August 2014, the FASB issued ASU No 2014-15, "Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern," which the intent is to define the Company's responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. This ASU will be effective for the Company November 1, 2017. The Company will prospectively apply the guidance as applicable and does not expect ASU 2014-15 to have a material impact on its statement of financial position or financial statement disclosures. In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers," which clarifies existing accounting literature relating to how and when a company recognizes revenue. Under ASU 2014-09, a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods and services. ASU 2014-09 will be effective for the Company November 1, 2017. The Company is in the process of determining what impact, if any, the adoption of this ASU will have on its financial position, results of operations and cash flows. In April 2014, the FASB issued ASU 2014-08, "Presentation of Financial Statements and Property, Plant, and Equipment — Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity,'' which revises what qualifies as a discontinued operation, changes the criteria for determining which disposals can be presented as discontinued operations and modifies related disclosure requirements. This ASU will be effective for the Company for applicable transactions occurring after October 1, 2015. The Company will prospectively apply the guidance to applicable transactions and does not expect ASU 2014-08 to have a material impact on its statement of financial position or financial statement disclosures. |
