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 42 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, which was filed with the U.S. Securities and Exchange Commission, or SEC, on March 15, 2016. In our opinion, these financial statements reflect all adjustments necessary to fairly state the results of operations for the three month periods ended March 31, 2016 and 2015, our financial position at March 31, 2016 and December 31, 2015, and the cash flows for the three month periods ended March 31, 2016 and 2015 on a basis consistent with our audited 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. 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 most recent Annual Report on Form 10-K for the year ended December 31, 2015, which we filed with the SEC on March 15, 2016. The results for the three month periods ended March 31, 2016 are not necessarily indicative of results for the year ending December 31, 2016 or any other future periods. 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 earning 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, the ASU 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 chosen to apply ASU 2015-17 on a prospective basis. Therefore, the prior periods were not retroactively adjusted. Except for per share data or as otherwise indicated, all dollar amounts presented in the tables are in thousands.
