Quarterly Financial Information Disclosure [Abstract]
Interim Financial Statements	Note 1. Interim Financial Statements We are a diversified industrial company and a leading global manufacturer of high precision bearing components, industrial plastic products and precision metal components to a variety of markets on a global basis. We have 41 manufacturing plants in North America, Western Europe, Eastern Europe, South America and China. Our business is aggregated into three reportable segments, the Precision Bearing Components Group (formerly known as our Metal Bearing Components Group), the Precision Engineered Products Group (formerly known as our Plastics and Rubber Components Group) and the Autocam Precision Components Group. As used in this Quarterly Report on Form 10-Q, the terms “NN”, “the Company”, “we”, “our”, or “us” mean NN, Inc. and its subsidiaries. The accompanying Condensed Consolidated Financial Statements of NN, Inc. have not been audited, except that the Condensed Consolidated Balance Sheet at December 31, 2015 was derived from our audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2015 (the “2015 Annual Report”), which was filed with the U.S. Securities and Exchange Commission, or the SEC, on March 15, 2016. In our opinion, these Condensed Consolidated Financial Statements reflect all adjustments necessary to fairly state the results of operations for the three and six month periods ended June 30, 2016 and 2015, our financial position at June 30, 2016 and December 31, 2015, and the cash flows for the three and six month periods ended June 30, 2016 and 2015 on a basis consistent with our audited consolidated financial statements. These adjustments are of a normal recurring nature and are, in the opinion of management, necessary to present fairly our financial position and operating results for the interim periods. Included in Selling, general and administrative expense line item within the Condensed Consolidated Statement of Net Income during the three months ended June 30, 2016 is an out of period adjustment in the amount of $0.4 million, to correct compensation expense recorded with respect to share – based awards previously granted to executives who, either at the time of such grant or during the applicable vesting period, were eligible to retire from the Company, upon which the vesting of all or a portion of these awards would be accelerated. Certain information and footnote disclosures normally included in the consolidated financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted from the interim financial statements presented in this Quarterly Report on Form 10-Q. These unaudited, Condensed Consolidated Financial Statements should be read in conjunction with our audited consolidated financial statements and the notes thereto included in our 2015 Annual Report. The results for the six months ended June 30, 2016 are not necessarily indicative of results for the year ending December 31, 2016 or any other future periods. Newly Adopted Accounting Standards During the first quarter of 2016, we adopted the following Accounting Standard Updates (“ASU”), and as necessary, certain reclassifications have been made to conform to the current year presentation: We adopted ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”), which provides guidance on simplifying the presentation of debt issuance costs on the balance sheet. To simplify presentation of debt issuance costs, the amendments in ASU 2015-03 require 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, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this update. In accordance with ASU 2015-03, we are applying the new guidance on a retrospective basis, wherein the balance sheet of each individual period presented was adjusted to reflect the period-specific effects of applying the new guidance. We adopted ASU No. 2015-11, Inventory (Topic 330) - Simplifying the Measurement of Inventory (“ASU 2015-11”), which simplifies the subsequent measurement of inventories by replacing the lower of cost or market test with a lower of cost and net realizable value test. The subsequent measurement of inventory test, historically three measurements under lower of cost or market, is replaced by lower of cost and net realizable value test. Thus, we will compare the cost of inventory to only one measure, its net realizable value. When evidence exists that the net realizable value of inventory is less than its cost (due to damage, physical deterioration, obsolescence, changes in price levels or other causes), we will recognize the difference as a loss in earnings in the period in which it occurs. In accordance with ASU 2015-11, we are applying the new guidance on a prospective basis. We adopted ASU No. 2015-16, Business Combinations (Topic 805) - Simplifying the Accounting for Measurement-Period Adjustments (“ASU 2015-16”), which eliminates the requirement that an acquirer in a business combination account for measurement-period adjustments retrospectively. Instead, we will recognize a measurement-period adjustment during the period in which we determine the amount of the adjustment, including the effect on earnings of any amounts it would have recorded in previous periods if the accounting had been completed at the acquisition date. In accordance with ASU 2015-16, we are applying the new guidance on a prospective basis to adjustments to provisional amounts that occur after December 31, 2015. That is, ASU 2015-16 applies to open measurement periods, regardless of the acquisition date. We adopted ASU No. 2015-17, Income Taxes (Topic 740), Balance Sheet Classification of Deferred Taxes (“ASU 2015-17”). We will classify all deferred tax assets and liabilities as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. In addition, we will no longer allocate valuation allowances between current and noncurrent deferred tax assets because those allowances also will be classified as noncurrent. We have elected to apply ASU 2015-17 on a prospective basis. Therefore, the prior periods were not retroactively adjusted. Issuance of New Accounting Standards In 2014, the Financial Accounting Standards Board (FASB) and International Accounting Standards Board (IASB) issued the joint revenue recognition standard. Since its release, there have been multiple proposed and finalized amendments made to the revenue recognition standard. In 2016, the FASB and IASB also issued separate lease accounting standards. The revenue recognition standard is effective for public companies beginning January 1, 2018 with full retrospective or modified retrospective adoption permitted. Both standards will significantly change current revenue and lease accounting practices, processes, systems, controls, and disclosures and take time and resources to adopt. On February 25, 2016, the FASB issued ASU 2016-02, Leases (“ASU 2016-02”). ASU 2016-02 creates Topic 842, Leases, in the FASB Accounting Standards Codification (FASB ASC) and supersedes FASB ASC 840, Leases. Entities that hold numerous equipment and real estate leases, in particular those with numerous operating leases, will be most affected by the new guidance. The leasing accounting standard is effective for public companies beginning January 1, 2019 with modified retrospective adoption required and early adoption permitted. The amendments in ASU 2016-02 are expected to impact balance sheets at many companies by adding lease-related assets and liabilities. This may affect compliance with contractual agreements and loan covenants. We are currently evaluating the impacts of the revenue recognition and lease accounting standards on our financial position or results of operations and related disclosures. Except for per share data or as otherwise indicated, all dollar amounts presented in the tables in these Notes to the Condensed Consolidated Financial Statements are in thousands.
