Accounting Policies [Abstract]
Summary of Significant Accounting Policies and Practices	1) Summary of Significant Accounting Policies and Practices a) Description of Business NN, Inc. is 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 Asia. As used in this Annual Report on Form 10-K, the terms “NN,” “the Company,” “we,” “our,” or “us” mean NN, Inc. and its subsidiaries. b) Cash We consider all highly liquid investments with an original maturity of three months or less as cash equivalents. c) Inventories Inventories are stated at the lower of cost or market. Cost is determined using the average cost method which approximates the first in first out method. Our policy is to expense abnormal amounts of idle facility expense, freight, handling cost, and waste included in cost of products sold. In addition, we allocate fixed production overheads based on the normal production capacity of our facilities. Inventory valuations were developed using normalized production capacities for each of our manufacturing locations and the costs from excess capacity or under-utilization of fixed production overheads were expensed in the period incurred and are not included as a component of inventory valuation. Inventories also include tools, molds and dies in progress that we are producing and will ultimately sell to our customers. This activity is principally related to our Autocam Precision Components and Precision Engineered Products Groups. These inventories are carried at the lower of cost or market. d) Property, Plant and Equipment Property, plant and equipment are stated at cost less accumulated depreciation. Assets to be disposed of are stated at lower of depreciated cost or fair market value less estimated selling costs. Expenditures for maintenance and repairs are charged to expense as incurred. Major renewals and betterments are capitalized. When a property item is retired, its cost and related accumulated depreciation are removed from the property accounts and any gain or loss is recorded in the consolidated Statements of Operations and comprehensive income. We review the carrying values of long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Property, plant and equipment includes tools, molds and dies principally used in our Autocam Precision Components and Precision Engineered Products Groups that are our property. Depreciation is provided on the straight-line method over the estimated useful lives of the depreciable assets for financial reporting purposes. For leasehold improvements and buildings under capital lease, we depreciate these over the shorter of useful lives or the lease term. In the event we abandon and cease to use certain property, plant, and equipment, depreciation estimates are revised and, in most cases, depreciation expense will be accelerated to reflect the shortened useful life of the asset. e) Revenue Recognition We recognize revenues based on the stated shipping terms with customers when these terms are satisfied and the risks of ownership are transferred to the customers. We have an inventory management program for certain Precision Bearing Components Group customers whereby revenue is recognized when products are used by customers from consigned stock, rather than at the time of shipment. Under both circumstances, revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred, the sellers’ price is fixed and determinable and collectability is reasonably assured. f) Accounts Receivable Accounts receivable are recorded upon recognition of a sale of goods and ownership and risk of loss is assumed by the customer. Substantially all of our accounts receivable are due primarily from the core served markets. In establishing allowances for doubtful accounts, we perform credit evaluations of our customers, considering numerous inputs when available including the customers’ financial position, past payment history, relevant industry trends, cash flows, management capability, historical loss experience and economic conditions and prospects. Accounts receivable are written off or allowances established when considered to be uncollectible or at risk of being uncollectible, respectively. g) Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. Provision has not been made for income taxes on unremitted earnings of foreign subsidiaries as these earnings are deemed to be permanently reinvested. We recognize income tax positions that meet the more likely than not threshold and accrue interest and potential penalties related to unrecognized income tax positions which are recorded as a component of the provision (benefit) for income taxes. h) Net Income Per Common Share Basic income per share reflects reported earnings divided by the weighted average number of common shares outstanding. Diluted income per share include the effect of dilutive stock options and the respective tax benefits, unless inclusion would not be dilutive. i) Share Based Compensation The cost of stock options, stock awards and performance based stock units are expensed as compensation expense over the vesting periods based on the fair value at the grant date. (See Note 9 of the Notes to the Consolidated Financial Statements) We use the Black Scholes financial pricing model for our stock options, and a Monte Carlo simulation for the performance based stock units to determine the fair value as these awards as they are not traded in open markets. We account for stock awards by recognizing compensation expense ratably over the vesting period as specified in the award. Compensation expense to be recognized is based on the stock price at date of grant. j) Principles of Consolidation Our consolidated financial statements include the accounts of NN, Inc. and its subsidiaries. All of our subsidiaries are 100% owned (except for RFK which we own 99.7% and our Chinese joint venture noted below) and all are included in the consolidated financial statements for the years end December 31, 2015, 2014 and 2013. All significant inter-company profits, transactions, and balances have been eliminated in consolidation. With the acquisition of Autocam Corporation (see Note 2), we acquired a 49% interest in a Chinese joint venture. This joint venture is not consolidated within the financial statements of NN, Inc. and is accounted for under the equity method (see Note 16). k) Foreign Currency Translation Assets and liabilities of our foreign subsidiaries are translated at current exchange rates, while revenue, costs and expenses are translated at average rates prevailing during each reporting period. Translation adjustments arising from the translation of foreign subsidiary financial statements are reported as a component of other comprehensive income and accumulated other comprehensive income within stockholders’ equity. In addition, transactions denominated in foreign currencies, including intercompany transactions, are initially recorded at the current exchange rate at the date of the transaction. The balances are adjusted to the current exchange rate as of each balance sheet date and as of the date when the transaction is consummated. Transaction gains or losses, excluding intercompany loan transactions, are expensed in either cost of products sold or selling, general and administrative lines in the Consolidated Statements of Operations and Comprehensive Income (Loss) as incurred and were immaterial to the years ended December 31, 2015, 2014 and 2013. Transaction gains or losses on intercompany loan transactions are recognized in the other income, net line in the Consolidated Statements of Operations and Comprehensive Income (Loss) as incurred. l) Goodwill and Other Indefinite Lived Intangible Assets We recognize the excess of the purchase price of an acquired entity over the fair value of the net identifiable assets as goodwill. Goodwill is tested for impairment on an annual basis as of October 1 and between annual tests if a triggering event occurs. The impairment procedures are performed at the reporting unit level for the reporting units that have goodwill. In September 2011, the FASB issued a revised accounting standard, intended to reduce the cost and complexity of the annual goodwill impairment test by providing entities an option to perform a “qualitative” assessment to determine whether further impairment testing is necessary. Specifically, an entity has the option to first assess qualitative factors to determine whether it is necessary to perform the current two-step test. If an entity believes, as a result of its qualitative assessment, that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, the quantitative impairment test is required. Otherwise, no further testing is required. For the years ended, December 31, 2015 and 2014, we determined it was more appropriate to perform a full step 1 goodwill test. The decision to perform a qualitative assessment or a complete step 1 analysis is an annual decision made by management. Based on the results of the step 1 analysis fair value of the reporting units exceeded the carrying value of the reporting units at December 31, 2015 and 2014. If the qualitative assessment indicates it is more likely than not that the fair value is less than the carrying value, GAAP prescribes a two-step process for testing for goodwill impairments. The first step is to determine if the carrying value of the reporting unit with goodwill is less than the related fair value of the reporting unit. We consider three main approaches to value (cost, market and income) the fair value of the reporting unit and market based multiples of earning and sales methods obtained from a grouping of comparable publicly trading companies. We believe this methodology of valuation is consistent with how market participants would value reporting units. The discount rate and market based multiples used are specifically developed for the unit tested regarding the level of risk and end markets served. Even though we do use other observable inputs (Level 2 inputs) the calculation of fair value for goodwill would be most consistent with Level 3 inputs. If the carrying value of the reporting unit including goodwill is less than fair value of the reporting unit, the goodwill is not considered impaired. If the carrying value is greater than fair value then the potential for impairment of goodwill exists. The potential impairment is determined by allocating the fair value of the reporting unit among the assets and liabilities based on a purchase price allocation methodology as if the reporting unit was acquired in a business combination. The fair value of the goodwill is implied from this allocation and compared to the carrying value with an impairment loss recognized if the carrying value is greater than the implied fair value. We base our fair value estimates, in large part, on management business plans and projected financial information which are subject to a high degree of management judgment and complexity. Actual results may differ from projections and the differences may be material. m) Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed Of Long-lived tangible and intangible assets subject to amortization are tested for recoverability when changes in circumstances indicate the carrying value of these assets may not be recoverable. A test for recoverability is also performed when management has committed to a plan to dispose of a reporting unit or asset group. Assets to be held and used are tested for recoverability when indications of impairment are evident. Recoverability of a long-lived tangible and intangible asset is evaluated by comparing its carrying value to the future estimated undiscounted cash flows expected to be generated by the asset or asset group. If the asset is not recoverable the asset is considered impaired and adjusted to fair value which is then depreciated/amortized over its remaining useful life. Assets to be disposed of are carried at the lesser of carrying value or fair value less costs of disposal. n) Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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. Actual results could differ from those estimates. o) Fair Value Measurements Fair value principles prioritize valuation inputs across three broad levels. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based on the assumptions used to measure assets and liabilities at fair value. An asset or liability’s classification within the various levels is determined based on the lowest level input that is significant to the fair value measurement. p) Recently Issued Accounting Standards In May 2014, the Financial Accounting Standards Board (“FASB”) and International Accounting Standards Board jointly issued new principles-based accounting guidance for revenue recognition that will supersede virtually all existing revenue guidance, Revenue from Contracts with Customers (Topic 606). The core principle of this guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. To achieve the core principle, the guidance establishes the following five steps: 1) identify the contract(s) with a customer, 2) identify the performance obligation in the contract, 3) determine the transaction price, 4) allocate the transaction price to the performance obligations in the contract, and 5) recognize revenue when (or as) the entity satisfies a performance obligation. The guidance also details the accounting treatment for costs to obtain or fulfill a contract. Lastly, disclosure requirements have been enhanced to provide sufficient information to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. This guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early application is not permitted. We are currently evaluating the impact this new guidance is expected to have on our financial position or results of operations and related disclosures. In August 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40), which provides guidance about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. The amendments require management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles that are currently in U.S. auditing standards. Specifically, the amendments (1) provide a definition of the term “substantial doubt”, (2) require an evaluation every reporting period including interim periods, (3) provide principles for considering the mitigating effect of management’s plans, (4) require certain disclosures when substantial doubt is alleviated as a result of consideration of management’s plans, (5) require an express statement and other disclosures when substantial doubt is not alleviated, and (6) require an assessment for a period of one year after the date that the financial statements are issued (or available to be issued). ASU 2014-15 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period and early adoption is permitted. We are currently evaluating the impact this new guidance is expected to have on our financial position or results of operations and related disclosures. In April 2015, the FASB issued 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 No. 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. ASU 2015-03 is effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period and early adoption is permitted for financial statements that have not yet been previously issued. In accordance with ASU No. 2015-03, companies should apply the new guidance on a retrospective basis, wherein the balance sheet of each individual period presented should be adjusted to reflect the period-specific effects of applying the new guidance. Upon transition, an entity is required to comply with the applicable disclosures for a change in an accounting principle. Adoption is not expected to have a material effect on our consolidated financial statements, but will affect balance sheet classification. We are currently evaluating the impact this new guidance is expected to have on our financial position or results of operations and related disclosures. In July 2015, the FASB issued 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 guidance applies only to inventories for which cost is determined by methods other than last-in first-out (“LIFO”) and the retail inventory method. The guidance in ASU No. 2015-11 is effective for periods beginning after December 15, 2016 and early adoption is permitted. We are currently evaluating the impact, if any, adoption will have on its financial position and results of operations. In July 2015, the FASB issued ASR No AUS 2015-12, Plan Accounting: Defined Benefit Pension Plans (Topic 960), Defined Contribution Pension Plans (Topic 962), Health and Welfare Benefit Plans (Topic 965), (Part I) Fully Benefit-Responsive Investment Contracts, (Part II) Plan Investment Disclosures, (Part III) Measurement Date Practical Expedient (consensuses of the FASB Emerging Issue Task Force) (ASU 2015-12). The standard eliminates requirements that employment benefit plans measure the fair value of fully benefit-responsive investment contracts (FBRICs) and provide the related fair value disclosures. As a result. FBRICs are measured, presented and disclosed only at contract value. Also, plans will be required to disaggregate their investments measured using fair value by general type, either on the face of the financial statements or in the notes, and self-directed brokerage fair value of investments by general type or individual investments equal to or greater than 5% of net assets available for benefits. In addition, a plan with a fiscal year end that doesn’t coincide with the end of a calendar month is allowed to measure its investments and investment-related accounting using month end closest to its fiscal year end. The new guidance for FBRICs and plan investment disclosures should be applied retrospectively, the measurement date practical expedient should be applied prospectively. The guidance is effective for fiscal years beginning after December 15, 2015. Earlier application is permitted. We are currently evaluating the impact this new guidance is expected to have on our financial position or results of operations and related disclosures. In September 2015, the FASB issued 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, an acquirer will recognize a measurement-period adjustment during the period in which it determines 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. The guidance is effective for fiscal years, including interim periods within fiscal years beginning after December 15, 2015. Early adoption is permitted. In November 2015, The FAS issues ASU No. 2015-17, Income Taxes (Topic 740) - Balance Sheet Classification of Deferred Taxes (“ASU 2017-17”). Companies are required to classify all deferred tax assets and liabilities as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. Also, companies will no longer allocation valuation allowances between current and noncurrent deferred tax assets because those allowances also will be classified as noncurrent. Since early adoption of the guidance is permitted, companies can start applying it in interim and annual financial statements that have not yet been issued. The guidance is effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. We are currently evaluating the impact this new guidance is expected to have on our financial position or results of operations and related disclosures. In February 2016, the FASB issued a new lease accounting standard. The key objective of the new standard is to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Lessees will need to recognize a right-of-use asset and a lease liability for virtually all of their leases (other than leases that meet the definition of a short-term lease). For income statement purposes, a dual model has been retained, with leases to be designated as operating leases or finance leases. Expenses will be recognized on a straight-line basis for operating leases, and a front-loaded basis for finance leases. For public entities, the new standard is effective for periods beginning after December 15, 2018, with early adoption permitted. The new standard must be adopted using a modified retrospective transition, and provides for certain practical expedients. The Company is currently evaluating the impact of the new standard on its financial position, results of operations and cash flows. q) Business Combinations We allocate the total purchase price of the acquired tangible and intangible assets acquired and liabilities assumed based on their estimated fair values as of the business combination date, with the excess purchase price recorded as goodwill. The purchase price allocation process required us to use significant estimates and assumptions, including fair value estimates, as of the business combination date. Although we believe the assumptions and estimates we have made are reasonable and appropriate, they are based in part on historical experience and information obtained from management of the acquired company, in part based on valuation models that incorporate projections of expected future cash flows and operating plans and are inherently uncertain. Valuations are performed by management or third party valuation specialists under management’s supervision. In determining the fair value of assets acquired and liabilities assumed in business combinations, as appropriate, we may use one of the following recognized valuation methods: the income approach (including discounted cash flows from relief from royalty and excess earnings model), the market approach and/or the replacement cost approach. Examples of significant estimates used to value certain intangible assets acquired include but are not limited to: • sales volume, pricing and future cash flows of the business overall; • future expected cash flows from customer relationships, and other identifiable intangible assets, including future price levels, rates of increase in revenue and appropriate attrition rate; • the acquired company’s brand and competitive position, royalty rate quantum, as well as assumptions about the period of time the acquired brand will continue to benefit to the combined company’s product portfolio; and • cost of capital, risk-adjusted discount rates and income tax rates. However, different assumptions regarding projected performance and other factors associated with the acquired assets may affect the amount recorded under each type of assets and liabilities, mainly between property plant and equipment, intangibles assets, goodwill and deferred income tax liabilities and subsequent assessment could result in future impairment charges. The purchase price allocation process also entails us to refine these estimates over a measurement period not to exceed one year to reflect new information obtained surrounding facts and circumstances existing at acquisition date.

PEP [Member]
Acquisitions	2) Acquisitions PEP On August 17, 2015, we entered into a stock purchase agreement with Precision Engineered Products Holding, Inc. (“PEP”), pursuant to which we agreed to acquire all the outstanding capital stock of PEP for $621.2 million. On October 19, 2015, we completed the acquisition of PEP (the “PEP Acquisition”). As a result of the PEP Acquisition, PEP became our wholly owned subsidiary. Concurrent with the acquisition, we: (i) entered into a new senior secured term loan facility in the amount of up to $525.0 million with a seven year maturity (the “New Term Loan Credit Facility”); (ii) entered into a new senior secured revolving credit facility in the amount of up to $100.0 million with a five year maturity (together with the New Term Loan Credit Facility, the “New Senior Credit Facilities”); and (iii) issued of $300.0 million of 10.25% senior notes due 2020 (the “Senior Notes”). Proceeds from the New Term Loan Credit Facility and the Senior Notes, together with cash on hand, were used to finance the purchase price of the PEP Acquisition and pay down debt. (See Note 7 of the Notes to Consolidated Financial Statements). With the completion of the PEP Acquisition, we added a global manufacturer of highly engineered precision customized solutions serving the medical, electrical, automotive and aerospace end markets. We are in the process of finalizing fair market valuation relate to customary working capital adjustments and incomes taxes. The following table summarizes the preliminary purchase price allocation for the PEP Acquisition: Fair value of assets acquired and liabilities assumed October 19, Current assets $ 69,331 Property, plant, and equipment 56,163 Intangible assets subject to amortization 240,490 Other non-current assets 1,500 Goodwill 364,450 Total assets acquired $ 731,934 Current liabilities $ 21,131 Non-current deferred tax liabilities 87,578 Other non-current liabilities 2,029 Total liabilities assumed $ 110,738 Net asset acquired $ 621,196 A combination of income, market, and cost approaches were used for the valuation where appropriate, depending on the asset or liability being valued. Valuation inputs in these models and analyses gave consideration to market participant assumptions. Acquired intangible assets are primarily customer relationships and trade names. We continue our analysis of the PEP opening balance sheet and the purchase price allocation. In connection with the PEP Acquisition, we recorded goodwill, which represents the excess of the purchase price over the estimated fair value of tangible and intangible assets acquired, net of liabilities assumed. The goodwill is attributed primarily to PEP as a going concern and the fair value of expected cost synergies and revenues growth from PEP businesses. The going concern element represents the ability to earn a higher return on the combined assembled collection of assets and businesses of PEP than if those assets and businesses were to be acquired and managed separately. Other relevant elements of goodwill are the benefits of access to certain markets and the assembled work force. None of the goodwill is expected to be deducted for tax purposes. Property, plant and equipment acquired primarily included machinery and equipment for use in manufacturing operations. Additionally, a number of manufacturing sites and related facilities including leasehold improvements were acquired. Property, plant and equipment has been valued using the cost approach supported where available by observable market data which includes consideration of obsolescence. Intangible assets have been valued using the relief from royalty and multi-period excess earnings methods, both forms of the income approach supported by observable market data. Related to the PEP Acquisition during 2015 we recognized $8.7 million in transaction costs. During 2015, we expensed $18.7 million of deferred financing costs related to the acquisition. Transaction costs were expensed as incurred and are included in the “Acquisition related costs excluded from selling, general and administrative expenses” line item and deferred financing costs are included in the “Write-off of unamortized debt issuance costs” line items in the Consolidated Statements of Operations and Comprehensive Income (Loss). As required by purchase accounting, the acquired inventories were recorded at their estimated fair value. These inventories were sold in the fourth quarter 2015 resulting in a one-time $4.3 million increase in cost of sales. Beginning October 20, 2015, our consolidated results of operations include the results of the acquired PEP businesses. Since the date of the acquisition, sales revenue of $40.7 million and net loss of $(2.6) million (including the $4.3 million for the one-time increase in cost of goods sold, and $5.2 million for the amortization of backlog intangibles) has been included in our financial statements. The unaudited pro forma financial results for the years ended December 31, 2015 and 2014 combine the consolidated results of NN and PEP giving effect to the PEP Acquisition as if it had been completed on January 1, 2014, the beginning of the comparable prior annual reporting period presented. Additionally, the pro forma statement of income for the year ended December 31, 2014 gives effect to the Autocam acquisition, which was completed on August 29, 2014; the results of operations of Autocam have been consolidated in our results from that date. The unaudited pro forma financial results presented below do not include any anticipated synergies or other expected benefits of the acquisition. This unaudited pro forma financial information is presented for informational purposes only and is not indicative of future operations or results had the acquisition been completed as of January 1, 2014. The unaudited pro forma financial results include certain adjustments for additional depreciation and amortization expense based upon the fair value step-up and estimated useful lives of PEP depreciable fixed assets and definite-life amortizable assets acquired in the transaction. The provision for income taxes has also been adjusted for all periods, based upon the foregoing adjustments to historical results. Year ended December 31, 2015 2014 Pro forma sales $ 851,583 $ 863,619 Pro forma net (loss) income $ 14,010 $ (7,560 ) Basic income (loss) per share $ 0.66 $ (0.41 ) Diluted income (loss) per share $ 0.65 $ (0.40 ) The pro forma net income for the year ended December 31, 2014 includes certain items, such as financing, integration, and transaction costs historically recorded by NN and PEP directly attributable to the acquisition, which will not have an ongoing impact. These items include transaction, integration, and financing related costs incurred by NN and PEP of $8.7 million and $12.3 million, net of tax, respectively during 2015 and reported in the year ended December 31, 2014 pro forma net income above. Autocam On August 29, 2014, we completed our merger with Autocam Corporation (“Autocam”), for $256.8 million in cash and $31.7 million in shares of our common stock. Additionally, we assumed $29.8 million in Autocam debt and capital lease obligations. Autocam is a global leader in the engineering, manufacture and assembly of highly complex, system critical components for fuel systems, engines and transmission, power steering and electric motors. With the completion of the transaction, we became one of the top global manufacturers in the precision metal components space. The funding of the cash portion of the purchase price and acquisition costs was provided primarily from borrowings, including a $350.0 million term loan entered into concurrent with the acquisition. (See Note 7 of the Notes to Consolidated Financial Statements). During the fourth quarter of 2014, we finalized our valuation related to the assets acquired and liabilities assumed of Autocam. The facts and circumstances existed at the date of acquisition and, if known, would have affected the measurement of the amounts recognized at the date. As a result, we adjusted the preliminary allocation of the purchase price initially recorded at the Autocam acquisition date to reflect these measurement period adjustments. The following table summarizes the purchase price allocation for the Autocam merger: Fair value of assets acquired and liabilities assumed on August 29, 2014 September 30, 2014 December 31, Current assets $ 88,529 $ (1,182 ) $ 87,347 Property, plant, and equipment 146,120 7,065 153,185 Intangible assets subject to amortization 51,098 562 51,660 Investment in joint venture 35,595 — 35,595 Other non-current assets 2,170 3,898 6,068 Goodwill 77,548 (3,556 ) 73,992 Total assets acquired $ 401,060 $ 6,787 407,847 Current liabilities $ 34,320 $ 6,963 $ 41,283 Current maturities of long-term debt 6,547 — 6,547 Non-current deferred tax liabilities 46,998 (486 ) 46,512 Obligations under capital lease 18,350 — 18,350 Long-term debt, net of current portion 4,263 — 4,263 Other non-current liabilities 2,028 310 2,338 Total liabilities assumed $ 112,506 $ 6,787 $ 119,293 Net asset acquired $ 288,554 $ — $ 288,554 A combination of income, market, and cost approaches were used for the valuation where appropriate, depending on the asset or liability being valued. Valuation inputs in these models and analyses gave consideration to market participant assumptions. Acquired intangible assets are primarily customer relationships and trade names. We have finished our analysis of the Autocam opening balance sheet and consider the purchase price allocation final. In connection with the acquisition of Autocam, we recorded goodwill, which represents the excess of the purchase price over the estimated fair value of tangible and intangible assets acquired, net of liabilities assumed. The goodwill is attributed primarily to Autocam as a going concern and the fair value of expected cost synergies and revenues growth from combining our and the Autocam businesses. The going concern element represents the ability to earn a higher return on the combined assembled collection of assets and businesses of Autocam than if those assets and businesses were to be acquired and managed separately. Other relevant elements of goodwill are the benefits of access to certain markets and the assembled work force. None of the goodwill is expected to be deducted for tax purposes. Property, plant and equipment acquired primarily included machinery and equipment for use in manufacturing operations. Additionally, a number of manufacturing sites and related facilities including leasehold improvements were acquired. Property, plant and equipment has been valued using the cost approach supported where available by observable market data which includes consideration of obsolescence. Intangible assets have been valued using the relief from royalty and multi-period excess earnings methods, both forms of the income approach supported by observable market data. Related to the acquisition of Autocam, during 2014 we recognized $6.9 million in transaction costs. During 2014, we expensed $3.0 million of deferred financing costs and make whole interest payments related to the acquisition. Transaction costs were expensed as incurred and are included in the “Acquisition related costs excluded from selling, general and administrative expenses” line item and deferred financing costs are included in the “interest expense” line items in the Consolidated Statements of Operations and Comprehensive Income (Loss). As required by purchase accounting, the acquired inventories were recorded at their estimated fair value. These inventories were sold in the third quarter 2014 resulting in a one-time $1.2 million increase in cost of sales. Beginning September 1, 2014, our consolidated results of operations include the results of the acquired Autocam businesses. Since the date of the acquisition, sales revenue of $80.8 million and net income of $3.7 million (including the $1.2 million for the one-time increase in cost of goods sold) have been included in our financial statements. The unaudited pro forma financial results for the years ended December 31, 2014 and 2013 combine the consolidated results of NN and Autocam giving effect to the acquisition of Autocam as if it had been completed on January 1, 2013, the beginning of the comparable prior annual reporting period presented. The unaudited pro forma financial results presented below do not include any anticipated synergies or other expected benefits of the acquisition. This unaudited pro forma financial information is presented for informational purposes only and is not indicative of future operations or results had the acquisition been completed as of January 1, 2013. The unaudited pro forma financial results include certain adjustments for additional depreciation and amortization expense based upon the fair value step-up and estimated useful lives of Autocam depreciable fixed assets and definite-life amortizable assets acquired in the transaction. The provision for income taxes has also been adjusted for all periods, based upon the foregoing adjustments to historical results. Year ended December 31, 2014 2013 Pro forma sales $ 659,652 $ 606,690 Pro forma net income $ 19,573 $ 3,307 The pro forma net income for the year ended December 31, 2013 includes certain items, such as financing, integration, and transaction costs historically recorded by NN and Autocam directly attributable to the acquisition, which will not have an ongoing impact. These items include transaction, integration, and financing related costs incurred by NN and Autocam of $9.4 million and $3.8 million, net of tax, respectively during 2014 and reported in the year ended December 31, 2013 pro forma net income above. Other Acquisitions 2015 Caprock On May 29, 2015, we completed the acquisition of Caprock Manufacturing, Inc. and Caprock Enclosures, LLC (collectively referred to as “Caprock”) for approximately $9.1 million in cash. Caprock was a privately held plastic components supplier located in Lubbock, Texas. Caprock serves multiple end markets including aerospace, medical and general industrial. The results of Caprock have been consolidated since the date of acquisition as part of our Precision Engineered Products Group (formerly known as the Plastic and Rubber Components Group). We have finalized the fair value market valuations of all the net assets acquired. The preliminary purchase price allocation includes $1.3 million in net working capital, $3.0 million in property plant and equipment, $2.5 million in intangible assets, and $2.3 million in goodwill, which we expect to be fully deductible for tax purposes. The goodwill is attributable to expected cost synergies and revenue growth plus the assembled work force. 2014 We made three other acquisitions during 2014 that aggregated to $21.0 million in net assets acquired. Related to the acquisitions, we incurred transactions costs of $1.2 million from third parties during 2014, which were expensed as incurred in acquisition related costs excluded from selling, general and administrative within the Consolidated Statements of Operations and Comprehensive Income (Loss). Chelsea Grinding On July 15, 2014, we purchased Chelsea Grinding Company (“Chelsea”) for $3.1 million in cash. Chelsea is a hydraulic component manufacturer. We acquired Chelsea to achieve access to the adjacent hydraulic component market. Chelsea, which has been completely integrated into our Erwin Plant of the Metal Bearing Components Group, contributed revenues of approximately $1.1 million from the acquisition date to December 31, 2014. RFK Valjcici d. d. Konjic On June 20, 2014, we acquired 79.2% of the outstanding shares of RFK Valjcici d. d. Konjic (“RFK”) for $9.8 million in cash. RFK is a manufacturer of tapered rollers with operations in Konjic, Bosnia & Herzegovina. Its products, while complementary to our existing roller bearing components, will broaden our product offering and allow penetration into adjacent markets. We acquired up to 99.7% of the outstanding shares of RFK during the third quarter of 2014 for an additional $2.5 million in cash. RFK contributed revenues and net income of approximately $5.1 million and $0.2 million, respectively, from the date of acquisition to December 31, 2014. RFK currently exports all of its products, predominately to customers serving the European truck, industrial vehicle and railway markets. We will continue operations at the existing facilities in Bosnia & Herzegovina and rolled up the operations of RFK under our Metal Bearing Components Group. In addition, we have reported non-controlling interest of $32 thousand for RFK representing the fair value of the 0.30% of the shares outstanding we do not own as of December 31, 2014. V-S On January 30, 2014, we purchased the majority of the operating assets of V-S Industries, V-S Precision, LLC and V-S Precision SA de DV (collectively referred to as “V-S”) from the secured creditors of V-S Industries for $5.6 million in cash and assumed certain liabilities totaling $3.0 million. This was accounted for as business combination. V-S contributed revenues and net loss of approximately $14.7 million and $(1.0) million, including integration costs of $0.5 million net of tax, respectively, from the date of acquisition to December 31, 2014. V-S is a precision metal components manufacturer that supplies customers in a variety of industries including electric motors, HVAC, power tools, automotive and medical. The acquisition of V-S provides a complementary and broader product offering and allows penetration into adjacent markets. V-S has two locations in Wheeling, Illinois and Juarez, Mexico and we rolled up V-S’s operations under our Autocam Precision Components Group (formerly known as the Precision Metal Components Group). The cash paid to acquire all four businesses acquired in 2014 totaled $277.8 million ($256.8 million for Autocam and $21.0 million for the others) less cash acquired of $17.6 million for a net amount of $260.2 million. A portion of this amount ($2.5 million) was reported in cash flows from financing activities as that amount related to acquiring a non-controlling interest in RFK. The following table summarizes the final fair values of assets acquired and liabilities assumed at the date of acquisition with any adjustments to fair value since September 30, 2014. Assets acquired and liabilities assumed September 30, 2014 December 31, Current assets $ 5,688 $ (123 ) $ 5,565 Property, plant, and equipment 15,367 (31 ) 15,336 Intangible assets subject to amortization 2,705 — 2,705 Goodwill 2,038 456 2,494 Total assets acquired $ 25,798 $ 302 $ 26,100 Current liabilities $ 4,803 $ 302 $ 5,105 Total liabilities assumed $ 4,803 $ 302 $ 5,105 Net asset acquired $ 20,995 $ — $ 20,995 The intangible assets subject to amortization are for customer contracts and trade names totaling $2.7 million and have weighted average useful lives of approximately 11 years. Goodwill of $2.5 million arising from the acquisitions is attributable primarily to the assembled workforce of RFK and strategic market opportunities that are expected to arise from the acquisition of RFK and Chelsea.

Restructuring and Impairment Charges, excluding Goodwill Impairments, and Divestitures	3) Restructuring and Impairment Charges, excluding Goodwill Impairments, and Divestitures Below is a summary of all the impairment and restructuring charges in the Consolidated Statements of Operations and Comprehensive Income (Loss) during the year ended December 31, 2015 and 2014: (In Thousands of Dollars) 2015 2014 Impairment of intangible assets $ — $ 875 Impairment of tangible assets 887 — Restructuring charges 672 — Restructuring and impairment charges, excluding goodwill impairment $ 1,559 $ 875 The above charges are discussed below in detail. Impairments of Intangible Assets For the year ended December 31, 2014, an indefinite lived intangible asset within the Autocam Precision Components Group was impaired as management is in the process of phasing out the use of the trade name as a result of the Autocam acquisition. As such, an impairment charge of $0.9 million was included in the restructuring and impairment charges line of the Consolidated Statements of Operations and Comprehensive Income (Loss). Impairments of Tangible Assets and Restructuring Activity On November 5, 2015, we announced the closure of our Wheeling plant, which is included in the Autocam Precision Components Group. This closure directly relates to the integration plan developed with the Autocam acquisition in 2014. The majority of the sales and productive assets will be relocated to existing plants with the Autocam Precision Components Group. During the fourth quarter of 2015, we accrued a restructuring charge of approximately $0.7 million related to severance and employees, and $0.9 million in impairments related to assets at the Wheeling Plant. The closure is expected to be finalized during the first half of 2016. Divestiture On November 30, 2015, we announced the divestiture of Delta Rubber Company (“Delta Rubber”). Delta Rubber was part of our then-named Plastic and Rubber Components Group. Proceeds of approximately $2.5 million in cash were received and $0.5 million is in escrow. A $0.7 million gain on sale was recognized in the fourth quarter.

Debt	7) Debt Long-term debt and short-term debt at December 31, 2015 and December 31, 2014 consisted of the following: December 31, 2015 December 31, Borrowings under our $575.0 million Senior Secured Term Loan B bearing interest the greater of 1% or 3 month LIBOR (0.61270% at December 31, 2015) plus an applicable margin of 4.75% at December 31, 2015, expiring October 19, 2022, net of discount of $11.0 million. $ 562,580 $ — Borrowings under our $100.0 million Senior Secured Revolver bearing interest at LIBOR (0.4239% at December 31, 2015) plus an applicable margin of 3.50% at December 31, 2015, expiring October 19, 2020. 6,462 — Borrowings under our $250.0 million Senior Notes bearing interest at 10.25%, maturing on November 1, 2020, net of discount of $5.5 million. 244,509 — Borrowings under our $350.0 Term Loan B bearing interest at the greater of 1% or 3 month LIBOR (0.2560% at December 31, 2014) plus an applicable margin of 5.00% at December 31, 2014, expiring August 29, 2019 net of discount of $5.0 million. — 340,005 Borrowings under our $100.0 million ABL Revolver bearing interest at a floating rate equal to LIBOR (0.17125% at December 31, 2014) plus an applicable margin of 1.75% at December 31, 2014, expiring August 29, 2019. — — French Safeguard Obligations (Autocam) 2,000 2,560 Brazilian lines of credit and equipment notes (Autocam) 826 5,304 Chinese line of credit (Autocam) 3,696 2,317 Total debt 820,073 350,186 Less current maturities of long-term debt 11,714 22,160 Long-term debt, excluding current maturities of long-term debt $ 808,359 $ 328,026 On October 19, 2015, concurrent with the PEP Acquisition, we: (i) entered into the New Term Loan Credit Facility; (ii) entered into the New Senior Secured Revolving Credit Facility; and (iii) issued the Senior Notes. Proceeds from the New Term Loan Credit Facility and the Senior Notes were used to finance the purchase price of the PEP Acquisition and pay down debt. The New Senior Credit Facilities replaced our existing credit facilities. On November 9, 2015, an incremental term loan of $50.0 million was drawn on the New Term Loan Credit Facility and the proceeds were used to repurchase approximately $50.0 million of the Senior Notes. As of December 31, 2015, $13.0 million of net capitalized deferred financing costs related to the New Senior Credit Facilities were recorded on the consolidated balance sheet within other non-current assets. The interest applicable to borrowings under the New Senior Credit Facilities are based upon a fluctuating rate of interest measured by reference to either, at our option, (i) a base rate, plus an applicable margin, or (ii) the greater of the London Interbank Offered Rate (“LIBOR”) or 1.0%, plus an applicable margin. The initial applicable margin for all borrowings under the New Term Loan Credit Facility is 3.75% per annum with respect to base rate borrowings and 4.75% per annum with respect to LIBOR borrowings. The initial applicable margin for New Senior Secured Revolving Credit Facility borrowings is 2.5% per annum with respect to base rate borrowings and 3.5% per annum with respect to LIBOR borrowings, which shall be in effect until we provide a compliance certificate, as required by the credit agreement. Thereafter, the applicable margin shall be determined by reference to a ratio of our consolidated leverage ratio. Our obligations under the New Senior Credit Facilities are guaranteed by certain of our direct and indirect, existing and future domestic subsidiaries, subject to customary exceptions and limitations. The New Senior Credit Facilities are secured by a first priority lien over substantially all of NN’s and each guarantor’s assets, subject to certain customary exceptions. The New Senior Credit Facilities are subject to negative covenants that, among other things subject to certain exceptions, limit our ability and the ability of its restricted subsidiaries to: (i) incur liens; (ii) incur indebtedness; (iii) make investments and acquisitions, (iv) merge, liquidate or dissolve, (v) sell assets, including capital stock of subsidiaries; (vi) pay dividends on capital stock or redeem, repurchase or retire capital stock; (viii) alter our business; (viii) engage in transactions with our affiliates; and (ix) enter into agreements limiting subsidiary dividends and distributions. In the event borrowings under the New Senior Secured Revolving Credit Facility exceed 30.0% of the aggregate commitments under the revolver, we will become subject to a financial covenant that requires us to maintain a specified consolidated net leverage ratio. The credit agreement provides that we have the right to request one or more increases in the revolving loan commitments or term loan commitment up to $100.0 million in the aggregate. In total, including the additional $50.0 million incremental term loan, we have paid original issue discount fees of $11.3 million, which are being amortized into interest expense over the life of the New Senior Credit Facilities. $12.5 million in net capitalized loan origination costs related to our $350.0 million credit facility were written off as of October 19, 2015. $0.4 million in net capitalized loan origination costs related to the $100.0 million asset backed revolver were also written off as of October 19, 2015. The Senior Notes will mature on November 1, 2020. Interest will be payable semi-annually in arrears on May 1 and November 1 of each year, commencing May 2016. Under the Senior Notes, we received funds of $293.3 million, net of a discount of $6.8 million, which is being amortized into interest expense over the life of the Senior Notes. The Senior Notes will be guaranteed by each existing direct and indirect domestic restricted subsidiaries (excluding immaterial subsidiaries). The Senior Notes and guarantees will be senior unsecured obligations of the issuer and the guarantors, respectively, and will rank pari passu in right of payments with all existing and future senior debt and senior to all existing and future subordinated debt of the issuer and guarantors. The Senior Notes and guarantees will be effectively subordinated to all existing and future secured debt of the issuer and guarantors to the extent of the assets securing such debt. In addition, the Senior Notes and the guarantees will be structurally subordinated to all indebtedness and other liabilities and preferred stock of our subsidiaries that do not guarantee the Senior Notes. The Senior Notes have not been registered under the Securities Act of 1933, as amended, or any state securities law and may not be offered or sold within the United States or to, or for the benefit of, a U.S. person (as defined by Regulation S under the Securities Act) except in transactions exempt from, or not subject to, the registration requirements of the Securities Act. The Senior Notes were offered and sold only to persons reasonably believed to be “qualified institutional buyers” (as defined in Rule 144A under the Securities Act) and to persons outside the United States under Regulations S. We will use our commercially reasonable efforts to register notes having substantially identical terms (other than restrictions on transfer and additional interest) as the Senior Notes with the Commission as part of an offer to exchange freely tradable exchange notes for the Senior Notes. We will use our commercially reasonable effort to file a registration statement for the exchange notes with the Commission and cause that registration statement to be declared effective 300 days of the issue date of the Senior Notes. If we fail to register the Senior Notes, than annual interest rate on the Senior Notes will increase by 0.25%. The annual interest rate on the Senior Notes will increase by an additional 0.25% for each subsequent 90-day period during which a registration default continues, up to a maximum additional interest rate of 1.0% per year. Concurrent with the Autocam acquisition, on August 29, 2014 we entered into two new credit facilities consisting of a $350.0 million term loan facility (“Term Loan”) and a $100.0 million asset backed revolver (“ABL”). Borrowings under our New Senior Credit Facilities were used to satisfy all of our obligations under the Term Loan and the ABL. Under the Term Loan, we received funds of $344.8 million, net of a discount of $5.3 million, which is being amortized into interest expense over the life of the Term Loan. These new facilities were utilized to fund the Autocam acquisition and to provide for short-term Our Term Loan had a seven year maturity with a 5% per annum repayment. The agreement relating to the Term Loan was a covenant lite agreement with no financial covenants and contained customary restrictions on, among other things, additional indebtedness, liens on our assets, sales or transfers of assets, investments, issuance of equity securities, and merger, acquisition and other fundamental changes in our business including a “material adverse change” clause, which if triggered would have given the lenders the right to accelerate the maturity of the debt. Costs associated with entering into the credit facility were capitalized and will be amortized into interest expense over the life of the facility. As of December 31, 2014, $8.0 million of net capitalized loan origination costs related to the Term Loan were recorded on the consolidated balance sheet within other non-current assets. Our ABL had a five year maturity and has one springing financial covenant in the event our availability on the ABL fell below $8.0 million. The ABL contained customary restrictions on, among other things, additional indebtedness, liens on our assets, sales or transfers of assets, investments, issuance of equity securities, and mergers, acquisitions and other fundamental changes in our business including a “material adverse change” clause, which if triggered would have given the lenders the right to accelerate the maturity of the debt. The facility had a swing line feature to meet short term cash flow needs. Borrowings under this swing line were considered short term. We incurred costs as a result of issuing the ABL which have been recorded on the consolidated balance sheet within other non-current assets and are being amortized over the term of the notes. The unamortized balance at December 31, 2014 was $1.0 million. We believe the book values of the credit facilities described above approximate their fair values given the interest rates are variable and we entered into these facilities very close to the year ended December 31 2015 and 2014, at the then market rates for a company with our credit profile. Regarding the Senior Notes, since they are not syndicated and are currently not tradable, the present value is the face value of the outstanding Senior Notes. As part of the merger with Autocam, we assumed certain foreign credit facilities. These facilities relate to local borrowings in France, Brazil and China. These facilities are with financial institutions in the countries in which foreign plants operate and are meant to fund working capital and equipment purchases in those countries. Below is a description of the credit facilities. In 2008, Autocam filed “Procedure de Sauvegarde” (“Safeguard”) on behalf of each of their French subsidiaries, Autocam France, SARL and Bouverat Industries, SAS (“Bouverat”). They reached agreement with their creditors with claims subject to Safeguard protection in 2009. Provisions of the agreements allowed, at each creditor’s option, for the payment of a portion of the obligation in January 2010, or the entire obligation over a ten-year period. The liabilities carry a zero percent interest rate and are being paid annually until 2019. Amounts due as of December 31, 2015, to those creditors opting to be paid over a ten-year period totaled $2.0 million and are included in Current Maturities of Long-Term debt $0.4 million and long-term debt excluding current maturities of long-term debt $1.6 million. The Brazilian lines of credit include facilities with certain Brazilian banks used to fund working capital needs, while the equipment notes represent borrowings from certain Brazilian banks to fund equipment purchases for Autocam’s Brazilian plants. The lines of credit have interest rates of 2.5% to 9.1%. The Chinese line of credit is a working capital line of credit with a Chinese bank bearing an interest rate of 4.95%. The aggregate maturities of long-term debt including current portion for each of the five years subsequent to December 31, 2015 are as follows: Year ending December 31, 2016 $ 11,714 2017 6,426 2018 6,426 2019 6,418 2020 255,259 Thereafter 533,830 Total $ 820,073 On June 1, 2004, our wholly owned subsidiary, NN Asia, entered into a twenty year lease agreement with Kunshan Tian Li Steel Structure Co. LTD for the lease of land and building (approximately 110,000 square feet) in the Kunshan Economic and Technology Development Zone, Jiangsu, The People’s Republic of China. The fair value of the land and building were estimated to be approximately $0.5 million and $1.9 million (at current exchange rates), respectively and undiscounted annual lease payments are approximately $0.3 million (approximately $5.6 million aggregate non-discounted lease payments over the twenty year term). The lease is cancelable after the fifth, ninth, and fourteenth years without payment or penalty by us. In addition, after the end of year five and each succeeding year we can buy the land for a preset price per square meter value and the building for actual cost less depreciation. On October 1, 2011, our wholly owned subsidiary, NN Asia, entered into a twenty year lease agreement with Kunshan Tian Li Steel Structure Co. LTD for the lease of land and building adjacent to the current leased facility (approximately 75,000 square feet) in the Kunshan Economic and Technology Development Zone, Jiangsu, The People’s Republic of China. This lease was entered into to expand the production capacity of our current leased facility. The fair value of the land and building were estimated to be approximately $0.8 million and $1.1 million (at current exchange rates), respectively and undiscounted annual lease payments are approximately $0.2 million (approximately $3.6 million aggregate non-discounted lease payments over the twenty year term). The lease is cancelable after the fifth, ninth, and fourteenth years without payment or penalty by us. In addition, after the end of year five and each succeeding year we can buy the land for a preset price per square meter value and the building for actual cost less depreciation. Below are the aggregate minimum future lease payments under both capital leases together with the present value of the net minimum lease payments as of December 31, 2015: Year ending December 31, 2016 $ 460 2017 460 2018 460 2019 460 2020 460 Thereafter 2,893 Total minimum lease payments 5,193 Less interest included in payments above (1,935 ) Present value of minimum lease payments $ 3,258 With the Autocam acquisition, we assumed capital leases on certain buildings and equipment.

Employee Benefit Plans	8) Employee Benefit Plans We have defined contribution 401(k) profit sharing plans covering substantially all U.S. employees. All eligible employees may enroll in the plans on the first day of the month following their employment date. A participant may elect to contribute between 1% and 60% of their compensation to the plans, subject to Internal Revenue Service (“IRS”) dollar limitations. Participants age 50 and older may defer an additional amount up to the applicable IRS Catch Up Provision Limit. We provide a matching contribution, which is determined on an individual, participating company basis. All participant contributions are immediately vested at 100%. Contributions for all U.S. employees were $0.2 million, $0.8 million and $0.3 million in 2015, 2014, and 2013, respectively. Post-Employment Benefit Liabilities We provide certain post-employment benefits to employees at our Pinerolo and Veenendaal plants that are either required by law or are local labor practice. There is a plan at our Pinerolo plant and at our Veenendaal plant which are described below. In accordance with Italian law, we have an unfunded severance plan under which all Italian employees are entitled to receive severance indemnities (Trattamento di Fine Rapporto or “TFR”) upon termination of their employment. Effective January 1, 2007, the amount payable, based on salary paid, is remitted to a pension fund managed by a third party. The severance indemnities paid to the pension fund accrue approximately at the rate of 1/13.5 of the gross salaries paid during the year. The amounts accrued become payable upon termination of the individual employee, for any reason, e.g., retirement, dismissal or reduction in work force. Employees are fully vested in TFR benefits after their first year of service. We have a plan that covers our Veenendaal plant employees that provides an award for employees who achieve 25 or 40 years of service and an award for employees upon retirement. The plan is unfunded and the benefits are based on years of service and rate of compensation at the time the award is paid. The amounts shown in the table below represent the actual liabilities at December 31, 2015 and 2014 reported under accrued post-employment benefits in the Consolidated Balance Sheets for both plans combined. 2015 2014 Beginning balance $ 6,024 $ 6,920 Amounts accrued 53 1,111 Payments to employees/government managed plan (266 ) (1,186 ) Foreign currency impacts (622 ) (821 ) Ending balance $ 5,189 $ 6,024 Defined Benefit Plan Effective with the Autocam acquisition on August 29, 2014, we sponsor a defined benefit pension plan (the “Pension Plan”) for substantially all employees of the Bouverat, France plant. These benefits are calculated based on each employee’s years of credited service and most recent monthly compensation and service category. Employees become vested in accordance with governmental regulations in place at the time of retirement. For the purpose of calculating the actuarial present value of the benefit obligation under the Pension Plan, the discount rates assumed were 2.15% for 2015. The compensation growth rate was assumed was 3.0% for 2015. The measurement date was December 31, 2015. Set forth below is projected benefit obligation information for the Pension Plan and the plan activity for the years ended December 31, 2015 and 2014: 2015 2014 Accumulated benefit obligation at measurement date $ 950 $ 1,011 Effect of salary increases 494 526 Projected benefit obligation at measurement date $ 1,444 $ 1,537 Projected benefit obligation at date of acquisition $ 1,537 $ 1,549 Service and interest costs 103 35 Actuarial gains (losses) (15 ) 94 Benefits paid (22 ) — Effect of foreign currency translation gains and other (159 ) (141 ) Projected benefit obligation at measurement date $ 1,444 $ 1,537 Set forth below is net periodic benefit cost information for the Pension Plan for the years ended December 31, 2015 and 2014: 2015 2014 Service and interest costs $ 103 $ 35 Expected return on plan assets (11 ) (4 ) Amortization of prior service costs 28 6 Net periodic benefit cost $ 120 $ 37 We expect benefit payments under the Pension Plan to be: Year ending December 31, 2016 $ — 2017 15 2018 7 2019 71 2020 26 2021-2025 324 Total benefit payments 443 Set forth below is plan asset information for the Pension Plan: 2015 2014 Plan assets at fair value at measurement date $ 515 $ 589 Projected benefit obligations at measurement date (1,444 ) (1,537 ) Funded status $ (929 ) $ (948 ) Plan assets at fair value at date of acquisition $ 589 $ 655 Actual return on plan assets 9 3 Benefits paid (22 ) (12 ) Effect of foreign currency translation gains (61 ) (57 ) Plan assets at fair value at measurement date $ 515 $ 589 The assumed rate of return on assets of the Pension Plan was 2.0% for all periods presented. We have a targeted goal of allocating plan assets one-third to equity and two-thirds to fixed income securities. Actual allocations of Pension Plan assets between equity and fixed income securities were 23% and 77%, respectively, as of December 31, 2015. Our expected funding obligations under the Pension Plan in 2016 is $0.1 million.

Stock Based Compensation

Stock Based Compensation	12 Months Ended

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock Based Compensation	9) Stock Based Compensation We recognize compensation expense of all employee and non-employee director share-based compensation awards in the financial statements based upon the fair value of the awards over the requisite service or vesting period, less anticipated forfeitures. We account for stock awards by recognizing the fair value of the awarded stock at the grant date as compensation expense over the vesting period, less anticipated forfeitures. In the years ended December 31, 2015, 2014, and 2013, approximately $3.7 million, $2.6 million, and $2.2 million, respectively of compensation expense was recognized in selling, general and administrative expense for all share-based awards. The compensation expense recognized in the years ended December 31, 2015, 2014 and 2013 related to stock options was $0.9 million, $1.3 million and $1.4 million, respectively. The compensation expense related to stock awards in the years ended December 31, 2015, 2014 and 2013 was $2.4 million, $1.3 million and $0.8 million, respectively. The compensation expense related to performance based awards in the year ended December 31, 2015, was $0.4 million. As of December 31, 2015, we have approximately 827,476 maximum shares that can be issued as options, stock appreciation rights, and/or other stock based awards. Stock Option Awards Option awards are typically granted to non-employee directors and key employees on an annual basis. A single option grant is typically awarded to eligible employees and non-employee directors each year if and when granted by the Compensation Committee of the Board of Directors and occasionally individual grants are awarded to eligible employees. All employee and non-employee directors are awarded options at an exercise price equal to the closing price of our stock on the date of grant. The term life of options is ten years with vesting periods of generally three years for key employees and one year for non-employee directors. The fair value of our options cannot be determined by market value as they are not traded in an open market. Accordingly, the Black Scholes financial pricing model is utilized to determine fair value based on certain assumptions discussed below. During 2015, 2014 and 2013, we granted options to purchase 54,600, 108,620, and 353,600 shares, respectively, to certain key employees and non-employee directors. The weighted average grant date fair value of the options granted during the years ended December 31, 2015, 2014 and 2013 was $12.61, $9.48 and $5.17, respectively. Upon exercise of stock options, new shares of our stock are issued. The weighted average assumptions relevant to determining the fair value at the dates of grant are below: 2015 2014 2013 Term 6 years 6 years 6 years Risk free interest rate 1.43 % 1.75 % 0.87 % Dividend yield 1.11 % 1.43 % 0.00 % Expected volatility 59.22 % 56.75 % 57.00 % Expected forfeiture rate 3.00 % 3.00 % 3.00 % The expected volatility rate is derived from our actual common stock historical volatility over the same time period as the expected term. The volatility rate is derived by mathematical formula utilizing daily closing price data. The expected dividend yield is derived by a mathematical formula which uses the expected annual dividends over the expected term divided by the fair market value of our common stock at the grant date. The average risk-free interest rate is derived from United States Department of Treasury published interest rates of daily yield curves for the same time period as the expected term. The forfeiture rate is determined from examining the historical pre-vesting forfeiture patterns of past option issuances to key employees. While the forfeiture rate is not an input of the Black Scholes model for determining the fair value of the options, it is an important determinant of stock option compensation expense to be recorded. The term is derived from using the “Simplified Method” of determining stock option terms as described under the Securities and Exchange Commission’s Staff Accounting Bulletin 107. The following table provides a reconciliation of option activity for the year ended December 31, 2015: Options Shares Weighted- Weighted- Aggregate Outstanding at January 1, 2015 1,175 $ 11.40 Granted 55 $ 25.16 Exercised 179 $ 11.42 Forfeited or expired (17 ) $ 13.44 Outstanding at December 31, 2015 1,034 $ 12.09 5.8 $ 4,867 (1) Exercisable at December 31, 2015 832 $ 10.94 5.2 $ 556 (1) (1) The intrinsic value is the amount by which the market price of our stock was greater than the exercise price of any individual option grant at December 31, 2015. As of December 31, 2015, there was approximately $0.6 million and $1.1 million of unrecognized compensation costs for stock options and restricted stock, respectively, to be recognized over approximately two years. Cash proceeds from the exercise of options in the years ended December 31, 2015, 2014, and 2013 totaled approximately $2.0 million, $1.7 million, and $4.0 million, respectively. For the years ended December 31, 2015, 2014 and 2013, proceeds from stock options were presented exclusive of tax benefits in the Financing Activities section of the Consolidated Statements of Cash Flows. The total intrinsic value of options exercised during the years ended December 31, 2015, 2014 and 2013 was $2.6 million, $2.0 million and $1.4 million, respectively. Stock Awards During the year ended December 31, 2015, 2014 and 2013, we issued 114,475, 114,300 and 94,800 shares, respectively, of our common stock as awards to key employees and non-executive directors. The fair value of the 2015 shares issued was determined by using the grant date price of our common stock with a weighted average grant date value of $23.72. The recognized compensation expense for stock awards in the years ended December 31, 2015, 2014, and 2013 was approximately $2.4 million, $1.3 million, and $0.8 million, respectively. The shares issued in 2015, 2014 and 2013 vest over three years. Performance Based Awards On April 30, 2015, we awarded performance share units (the “PSUs”) to our executive officers. The PSUs are a form of long-term incentive compensation designed to directly align the interests of employees to the interests of our stockholders, and to create long-term stockholder value. The awards were made pursuant to the NN, Inc. 2011 Stock Incentive Plan and a Performance Share Unit Agreement. There were two tranches of PSUs awarded, PSUs based on total shareholder return (“TSR Awards”) and PSUs based on return on invested capital (“ROIC Awards”). The TSR Awards vest, if at all, upon our achieving a specified relative total shareholder return, which will be measured against the total shareholder return of the S&P SmallCap 600 Index during the period beginning on February 1, 2015 and ending December 31, 2017 (the “Performance Period”). The ROIC Awards will vest, if at all, upon our achieving a specified average return on invested capital during the Performance Period. If the PSUs do not vest at the end of the Performance Period, the PSUs will expire automatically. Upon vesting, the PSUs will be settled by the issuance of shares of our common stock, subject to the executive officer’s continued employment. The actual number of shares of common stock will be issued to each award recipient at the end of the Performance Period will be interpolated between a threshold and maximum payout amount based on actual performance results. No dividends will be paid on outstanding PSUs during the Performance Period; however, dividend equivalents will be paid based on the number of shares of common stock that are ultimately earned at the end of the Performance Period. With respect to the TSR Awards, a participant will earn 50% of the target number of PSUs for “Threshold Performance,” 100% of the target number of PSUs for “Target Performance,” and 150% of the target number of PSUs for “Maximum Performance.” With respect to the ROIC Awards, a participant will earn 35% of the target number of PSUs for “Threshold Performance,” 100% of the target number of PSUs for “Target Performance,” and 150% of the target number of PSUs for “Maximum Performance. For performance levels falling between the values show below, the percentages will be determined by interpolation. The following table establish the goals with respect to TSR and ROIC: TSR: Threshold Performance (50% of Shares) Target Performance (100% of Shares) Maximum Performance (150% of Shares) 35th Percentile 50th Percentile 75th Percentile ROIC: Threshold Performance (35% of Shares) Target Performance (100% of Shares) Maximum Performance (150% of Shares) 11 % 12.5 % 14 % During 2015, we awarded 35,775 TSR Awards and 35,775 ROIC Awards with a grant date fair value of $28.61 and $25.16 per unit, respectively. We estimate the grant date fair value of TSR Awards using the Monte Carlo simulation model, as the total shareholder return metric is considered a market condition under ASC 718. The grant date fair value of ROIC Awards is based on the closing price of a share of our common stock on the date of grant. The recognized compensation expense for the year ended December 31, 2015 was $0.4 million for all PSUs. Unrecognized compensation expense at December 31, 2015 was $1.5 million to be recognized over approximately two years.

Goodwill, Net	10) Goodwill, Net We completed our annual goodwill impairment review during the fourth quarters of 2015 and 2014. For the years ended December 31, 2015, 2014 and 2013, we concluded that there were no indicators of impairment at the reporting units with goodwill. The changes in the carrying amount of goodwill for the years ended December 31, 2015, 2014 and 2013 are as follows: (In thousands) Precision Autocam Precision Total Balance as of December 31, 2013 $ 8,624 $ — $ — $ 8,624 Currency impacts (1,169 ) — — (1,169 ) Goodwill acquired in acquisition 2,494 73,992 — 76,486 Balance as of December 31, 2014 $ 9,949 $ 73,992 $ — $ 83,941 Currency impacts (838 ) — — (838 ) Goodwill acquired in acquisition — — 366,795 366,795 Balance as of December 31, 2015 $ 9,111 $ 73,992 $ 366,795 $ 449,898 The cumulative accumulated impairment charges included in the reported goodwill balances at December 31, 2015, 2014 and 2013 were $40.0 million all of which were recorded during the years ended December 31, 2008 and 2007. The goodwill acquired in the 2015 acquisitions within the Precision Engineered Products Group was primarily related to the PEP Acquisition. (See Note 2 of the Notes to Consolidated Financial Statements). The goodwill balance related to the PEP Acquisition is derived from the value of the PEP reporting unit. This fair value was based in large part on management business plans and projected financial information which are subject to a high degree of management judgment and complexity. Actual results may differ from these projections and the differences may be material leading to a potential impairment of this goodwill if this reporting unit’s future results are not as forecasted. The goodwill acquired in acquisitions during 2014 within the Autocam Precision Components Group was acquired with the acquisition of Autocam (see Note 2 of the Notes to Consolidated Financial Statements). The goodwill balance related to the Autocam acquisition is derived from the value of the Autocam reporting unit. This fair value was based in large part on management business plans and projected financial information which are subject to a high degree of management judgment and complexity. Actual results may differ from these projections and the differences may be material leading to a potential impairment of this goodwill if this reporting unit’s future results are not as forecasted.

Goodwill and Intangible Assets Disclosure [Abstract]
Intangible Assets, Net	11) Intangible Assets, Net With the PEP Acquisition the Precision Engineered Products Group acquired a customer relationship intangible asset of $226.5 million, a trade name intangible asset of $6.3 million, a backlog and unfavorable leasehold intangible of $7.7 million. The intangible assets have preliminary estimated useful lives of 12 years for customer relationships, 8 years for trade name, the backlog and unfavorable leases will be amortized over the fourth quarter of 2015 and first quarter of 2016. After the estimated useful lives of the backlog and inventory, the estimated amortization of intangibles will be approximately $19.7 million a year. (See Note 2 of the Notes to Consolidated Financial Statements). With the Caprock acquisition, the Precision Engineered Products Group acquired $2.5 million of intangibles, approximately $0.1 in trade names and $2.4 million in customer relationships. The intangibles have preliminary useful lives of one year for trade names and 12 years for customer relationships. The estimated amortization of the intangibles for the first year will be approximately $0.3 million and $0.2 million for the years thereafter. (See Note 2 of the Notes to Consolidated Financial Statements). The Autocam Precision Components Group has an intangible asset not subject to amortization of $0.9 million related to the value of the trade names of Whirlaway. This indefinite lived intangible asset was impaired during the year ended December 31, 2014 as management is in the process of phasing out the use of the trade name as a result of the Autocam acquisition. As such, an impairment charge of $0.9 million was included in the restructuring and impairment charges line of the Consolidated Statements of Operations and Comprehensive Income (Loss). With the Autocam acquisition the Autocam Precision Components Group acquired a customer contract intangible asset of $46.2 million, a trade name intangible asset of $4.1 million, a developed technology intangible asset of $0.9 million, and net favorable leasehold intangible of $0.4 million. The trade names and customer relationship intangible assets have preliminary estimated useful lives of 15 years, the remaining intangibles have a five year useful life. The estimated amortization for the first five year will be approximately $3.6 million a year and $3.4 million thereafter. (See Note 2 of the Notes to Consolidated Financial Statements). The Precision Bearing Components Group acquired two customer contract intangible assets related to the acquisition of RKF and Chelsea and a trade name intangible asset related to the acquisition of RFK with an aggregate estimated fair value of $2.7 million. These intangible assets have weighted average useful lives of 10 years and are subject to amortization of approximately $0.3 million per year.

Segment Reporting [Abstract]
Segment Information	12) Segment Information We determined our reportable segments under the provisions of GAAP related to disclosures about segments of an enterprise. Our three reportable segments are based on differences in product lines. All of the facilities in the Precision Bearing Components Group are engaged in the production of precision steel balls, steel rollers, and metal retainers and automotive specialty products used primarily in the bearing industry. The Precision Engineered Products Group includes the Plastic and Rubber Components Group as presented in previous filings. The name of this segment was changed during 2015 after the PEP Acquisition and disposal of Delta Rubber. With the completion of the PEP Acquisition, we added a global manufacturer of highly engineered precision customized solutions serving the medical, electrical, automotive and aerospace end markets. The Autocam Precision Components Group is engaged in the design and manufacture of close-tolerance, specialty metal alloy components for mechanical and electromechanical systems using turning, grinding and milling processes. Currently, we manufacture components for use in fuel delivery, electromechanical motor, steering and braking systems for the automotive industry and highly engineered shafts, mechanical components, complex precision assembled and tested parts and fluid system components for the HVAC and fluid power industries. This segment was renamed with the acquisition of Autocam.

These costs impacted income from operations at Corporate by $10.9 million and $9.8 million for the years ended December 31, 2015 and 2014, respectively. Beginning October 20, 2015 and September 1, 2014, the Precision Engineered Products Group and Autocam Precision Components Group, respectively, include the results of the acquired PEP and Autocam businesses. Since the date of the PEP Acquisition, 2015 sales revenue of $40.7 million and net loss of $(2.6) million (including the $4.3 million for the one-time increase in cost of goods sold for inventory step-up, and $5.2 for the amortization of backlog intangible) has been included in this segment. During 2014 and since the date of the Autocam acquisitions, sales revenue of $80.8 million and net income of $3.7 million (including the $1.2 million for the one-time increase in cost of goods sold for inventory step-up) has been included in this segment.

Income Tax Disclosure [Abstract]
Income Taxes	13) Income Taxes Income (loss) before provision (benefit) for income taxes for the years ended December 31, 2015, 2014 and 2013 was as follows: Year ended December 31, 2015 2014 2013 Income (loss) before provision (benefit) for income taxes: United States $ (42,450 ) $ (9,341 ) $ 8,259 Foreign 19,500 22,513 16,919 Total $ (22,950 ) $ 13,172 $ 25,178 The loss of $42.5 million from domestic operations during 2015, was primarily driven from acquisition related charges (included in selling, general and administrative of $11.7 million, cost of products sold $7.5 million and write-off of debt issuance costs of $18.7 million) of which approximately $3.8 million was non-deductible as these costs were directly facilitative to the acquisitions. The loss of $9.3 million from domestic operations during 2014, was primarily driven from acquisition related charges of $14.8 million (included in selling, general and administrative, cost of products sold, and interest expense) of which approximately $6.0 million were non-deductible as these cost were directly facilitative to the acquisitions. Total income tax expense (benefit) for the years ended December 31, 2015, 2014, and 2013 was as follows: Year ended December 31, 2015 2014 2013 Current: U.S. Federal $ — $ — $ — State 420 37 179 Foreign 5,940 7,082 4,490 Total current expense $ 6,360 $ 7,119 $ 4,669 Deferred: U.S. Federal $ (13,391 ) $ 1,625 $ 3,594 State (1,869 ) (382 ) 145 U.S. deferred tax valuation allowance — (1,434 ) (818 ) Foreign (1,618 ) (1,142 ) 410 Total deferred expense (benefit) (16,878 ) (1,333 ) 3,331 Total expense (benefit) $ (10,518 ) $ 5,786 $ 8,000 A reconciliation of income taxes based on the U.S. federal statutory rate of 34% for each of the years ended December 31, 2015, 2014 and 2013 is summarized as follows: Year ended December 31, 2015 2014 2013 Income taxes at the federal statutory rate $ (7,803 ) $ 4,478 $ 8,561 Impact of incentive stock options — (145 ) 261 Decrease in U.S. valuation allowance — (1,434 ) (818 ) Foreign tax credit (additions) expiration (1,343 ) 2,736 818 Capital gain on return of basis — — — State taxes, net of federal taxes (1,592 ) (362 ) 198 Non-U.S. earnings taxed at different rates (2,308 ) (1,714 ) (834 ) Non-deductible mergers and acquisition costs 1,299 1,971 — R&D Tax credit (623 ) (529 ) — Joint Venture dividend 1,147 737 — Change in uncertain tax positions — — 32 Other permanent differences, net 705 48 (218 ) $ (10,518 ) $ 5,786 $ 8,000 The 2015 effective tax rate of 46% primarily reflects the impact of foreign earnings being taxed at lower rates. The 2014 effective tax rate of 44% reflects the impact of two items related to the merger and acquisition activity in 2014, including: (1) $2.0 million for non-deductible third party merger and acquisition as these costs were directly facilitative to the acquisitions; and (2) $1.3 million for the expiration of foreign tax credits that could not be utilized during 2014 because of the merger related acquisition costs as discussed below. In addition, the rate reflects an offset to the items above for the impact of foreign earnings taxed at lower rates of $1.7 million. The 2013 effective tax rate of 32% reflects the impact of foreign earnings being taxed at lower rates of $0.8 million. The tax effects of the temporary differences as of December 31, 2015, 2014 and 2014 are as follows: December 31, 2015 2014 2013 Deferred income tax liabilities: Tax in excess of book depreciation $ 42,345 $ 35,411 $ 6,673 Goodwill 1,554 1,949 2,213 Intangible assets 91,947 15,944 — Other deferred tax liabilities 897 1,924 63 Gross deferred income tax liabilities 136,743 55,228 8,949 Deferred income tax assets: Goodwill 1,666 2,411 3,215 Inventories 4,490 2,035 836 Pension/Personnel accruals 2,778 3,029 856 Net operating loss carry forwards 8,313 1,196 1,351 Foreign tax credits 3,242 290 3,026 Guarantee claim deduction 1,141 1,141 1,141 Credit carry forwards 2,582 1,853 — Accruals and reserves — — 114 Other deferred tax assets 2,510 1,926 832 Gross deferred income tax assets 26,722 13,881 11,371 Valuation allowance on deferred tax assets — — (1,434 ) Net deferred income tax assets 26,722 13,881 9,937 Net deferred income tax assets (liabilities) $ (110,021 ) $ (41,347 ) $ 988 With the PEP Acquisition, we assumed $87.6 million in net deferred tax liabilities primarily related to book and tax basis difference in fixed assets and intangibles (excluding goodwill). With the Autocam acquisition, we assumed $43.8 million in net deferred tax liabilities primarily related to book and tax basis differences in fixed assets and intangibles (excluding goodwill). As realization of certain deferred tax assets is not assured, management believes it is more likely than not that those net deferred tax assets will be realized. However, the amount of the deferred tax assets considered realizable could be reduced based on changing conditions. Below is a summary of the activity in the total valuation allowances during the years ended December 31, 2015, 2014 and 2013: Balance at Beginning of Year Additions Recoveries Balance at End of Year 2015 $ — $ — $ — $ — 2014 $ 1,434 $ — $ (1,434 ) $ — 2013 $ 2,252 $ — $ (818 ) $ 1,434 During 2014, the valuation allowance of $1.4 million on our previously recognized foreign tax credits was reduced by the full $1.4 million for credits which expired as of December 31, 2014. In addition to the foreign tax credits with the full valuation allowance, $1.3 million in foreign tax credits expired unused as of December 31, 2014. These foreign tax credits were not utilized during 2014, as management expected, due to the large amount of non-deductible mergers and acquisition costs incurred related to the four acquisitions completed in 2014. The remaining foreign tax credits, net operating loss and credit carry forwards are expected to be utilized before expiration. We record a valuation allowance when it is “more likely than not” that some portion or all of the deferred income tax assets will not be realized. In reaching this determination, we consider the future reversals of taxable temporary differences, future taxable income, exclusive of taxable temporary differences and carry forwards, taxable income in prior carryback years and tax planning strategies. Unremitted earnings of subsidiaries outside the United States are considered to be reinvested indefinitely at December 31, 2015. It is not practicable to determine the deferred tax liability for temporary differences related to those unremitted earnings. There has been no change in our long term international expansion plans as of December 31, 2015 and our intent and ability is to indefinitely reinvest our foreign earnings. We base this assertion on two factors. The first factor is our intention to invest in foreign countries that are strategically important to our Precision Bearing Components Group, Precision Engineered Products Group and our Autocam Precision Components Group businesses. With the acquisitions completed in 2015 and 2014, we have significantly expanded our international base of operations adding subsidiaries in Mexico, Bosnia and Herzegovina, Brazil, Poland, France and China which will require more foreign investment. Second, we have sufficient access to funds in the U.S. through projected free cash flows and the availability of our US credit facilities to fund currently anticipated domestic operational and investment needs. A reconciliation of the beginning and ending amounts of unrecognized tax benefits, excluding interest and penalties for the years ended December 31, 2015, 2014 and 2013 is as follows: 2015 2014 2013 Beginning balance $ 3,834 $ 873 $ 873 Additions for tax positions of prior years 2,516 3,589 — Reductions for tax positions of prior years (626 ) (628 ) — Ending balance $ 5,724 $ 3,834 $ 873 As of December 31, 2015, the $5.7 million of unrecognized tax benefits would, if recognized, impact our effective tax rate. The addition for tax positions of prior years was added as part of the purchase price allocation of PEP in 2015 of $2.2 million and Autocam in 2014 of $2.8 million and was included in the fair value of assets acquired and liabilities assumed. (See Note 2 of Notes to Consolidated Financial Statements.) Interest and penalties related to federal, state, and foreign income tax matters are recorded as a component of the provision for income taxes in our Statements of Operations. During 2015, we accrued $30 thousand in foreign interest and $0.3 million in US interest. During 2014, we accrued $31 thousand in foreign interest and $17 thousand in US interest. During 2013, we accrued $32 thousand in foreign interest and penalties. As of December 31, 2015, the total amount accrued for interest and penalties was $1.4 million. We or our subsidiaries file income tax returns in the U.S. federal jurisdiction, and in various states and foreign jurisdictions. With few exceptions, we are no longer subject to federal, state and local income tax examinations by tax authorities for years before 2012. We are no longer subject to non-U.S. income tax examinations within various European Union countries for years before 2010. We do not foresee any significant changes to our unrecognized tax benefits within the next twelve months.

Rent expense for 2015, 2014 and 2013 was $5.8 million, $4.5 million and $2.3 million, respectively. The following is a schedule by year of future minimum lease payments as of December 31, 2015 under operating leases that have initial or remaining non-cancelable lease terms in excess of one year.

The state tax authority notification disallowed state ICMS credits claimed on intermediary materials based on the argument that these items are not intrinsically related to the manufacturing processes. Autocam Brazil filed an administrative defense with the São Paulo state tax authority arguing, among other matters, that it should qualify for ICMS tax credit, contending that the intermediary materials are directly related to the manufacturing process. We believe we have substantial legal and factual defenses and plan to defend our interests vigorously. While we believe a loss is not probable we estimate the range of possible loss related to this assessment is from $0 to $6.0 million. No amount has been accrued at December 31, 2015 for this matter. We are entitled to indemnification from the former shareholders of Autocam, subject to the limitations and procedures set forth in the agreement and plan of merger. Management believes the indemnification would include amounts owed for the tax, interest and penalties related to the Brazil ICMS matter. All other legal matters All other legal proceedings are of an ordinary and routine nature and are incidental to our operations. Management believes that such proceedings should not, individually or in the aggregate, have a material adverse effect on our business, financial condition, results of operations, or cash flows. In making that determination, we analyze the facts and circumstances of each case at least quarterly in consultation with our attorneys and determine a range of reasonably possible outcomes. The procedures performed include reviewing attorney and plaintiff correspondence, reviewing any filings made and discussing the facts of the case with local management and legal counsel. We have not recognized any loss contingencies as December 31, 2015 and 2014.

Additionally, the fourth quarter was negatively impacted by $18.7 million in pre-tax costs and $12.0 million in after-tax costs incurred related to writing-off debt issuance costs to our former lenders related to the new debt entered into for the PEP Acquisition. The third and fourth quarters of 2014 were impacted by merger and acquisition related costs of $8.4 million and $1.5 million, respectively, pre-tax and $7.3 million and $3.2 million, respectively, after-tax related to the four acquisitions closed during 2014. Additionally, the third quarter was negatively impacted by $3.0 million in pre-tax costs and $1.9 million in after-tax costs incurred related to writing-off debt issuance costs and make whole interest payments to our former lenders related to the new debt entered into for the Autocam acquisition.

Accumulated Other Comprehensive Income	18) Accumulated Other Comprehensive Income The majority of our Accumulated Other Comprehensive Income balance relates to foreign currency translation of our foreign subsidiary balances. During the year ended December 31, 2015, we had other comprehensive loss of $21.9 million due to foreign currency translations and a $2.6 million loss due to change in fair value of interest rate hedge. During the year ended December 31, 2014, we had other comprehensive loss of $17.7 million due to foreign currency translations and a $0.4 million loss due to change in fair value of interest rate hedge. During the year ended December 31, 2013, we had other comprehensive income $3.9 million due to foreign currency translations. Income taxes on the foreign currency translation adjustments in other comprehensive income were not recognized because the earnings are intended to be indefinitely reinvested in those operations.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Interest Rate Hedging	19) Interest Rate Hedging Our policy is to manage interest expense using a mix of fixed and variable rate debt. To manage this mix effectively, we may enter into an interest rate swap in which we agree to exchange the difference between fixed and variable interest amounts calculated by reference to an agreed upon notional principal amount. Effective December 16, 2014, we entered into a $150 million swap that went into effect on December 29, 2015 (one year delayed start), at which time our rate was locked at 6.966% until December 31, 2018. Prior to December 16, 2014, we did not have any existing interest rate hedges. The hedge instrument will be 100% effective and as such the mark to market gains or losses on this hedge will be included in accumulated other comprehensive income (loss) to the extent effective, and reclassified into interest expense over the term of the related debt instruments.

Level 2 fair value is based on estimates using standard pricing models. These standard pricing models use inputs which are derived from or corroborated by observable market data such as interest rate yield curves, index forward curves, discount curves, and volatility surfaces. The counterparty to this derivative contract is a highly rated financial institutions which we believe carries only a minimal risk of nonperformance. We have elected to present the derivative contract on a gross basis in the Consolidated Statements of Financial Position within other current and other non-current assets and liabilities. Had we chosen to present the derivative contract on a net basis, we would have a derivative in a net liability position of $3.0 million and $0.4 million as of December 31, 2015 and 2014. We do not have any cash collateral due under such agreements.

Equity Offering	20) Equity Offering On July 1, 2015, we closed an underwritten registered public offering of common stock offered pursuant to a shelf registration statement on Form S-3 that was previously filed with, and declared effective by, the Securities Exchange Commission (the “SEC” or “Commission”). The total number of shares of common stock sold was 7,590,000 at a public offering price of $24.00 per share. All of the shares in the offering were sold by us. Our net proceeds from the offering, after deducting underwriting discounts and commissions and offering expenses, were approximately $173.1 million. Of these proceeds, $148.7 million was used for repayment of principal and interest on our debt.

Summary of Significant Accoun28

Summary of Significant Accounting Policies and Practices (Policies)	12 Months Ended
	Dec. 31, 2015
Accounting Policies [Abstract]
Description of Business	a) Description of Business NN, Inc. is 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 Asia. As used in this Annual Report on Form 10-K, the terms “NN,” “the Company,” “we,” “our,” or “us” mean NN, Inc. and its subsidiaries.
Cash	b) Cash We consider all highly liquid investments with an original maturity of three months or less as cash equivalents.
Inventories	c) Inventories Inventories are stated at the lower of cost or market. Cost is determined using the average cost method which approximates the first in first out method. Our policy is to expense abnormal amounts of idle facility expense, freight, handling cost, and waste included in cost of products sold. In addition, we allocate fixed production overheads based on the normal production capacity of our facilities. Inventory valuations were developed using normalized production capacities for each of our manufacturing locations and the costs from excess capacity or under-utilization of fixed production overheads were expensed in the period incurred and are not included as a component of inventory valuation. Inventories also include tools, molds and dies in progress that we are producing and will ultimately sell to our customers. This activity is principally related to our Autocam Precision Components and Precision Engineered Products Groups. These inventories are carried at the lower of cost or market.
Property, Plant and Equipment	d) Property, Plant and Equipment Property, plant and equipment are stated at cost less accumulated depreciation. Assets to be disposed of are stated at lower of depreciated cost or fair market value less estimated selling costs. Expenditures for maintenance and repairs are charged to expense as incurred. Major renewals and betterments are capitalized. When a property item is retired, its cost and related accumulated depreciation are removed from the property accounts and any gain or loss is recorded in the consolidated Statements of Operations and comprehensive income. We review the carrying values of long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Property, plant and equipment includes tools, molds and dies principally used in our Autocam Precision Components and Precision Engineered Products Groups that are our property. Depreciation is provided on the straight-line method over the estimated useful lives of the depreciable assets for financial reporting purposes. For leasehold improvements and buildings under capital lease, we depreciate these over the shorter of useful lives or the lease term. In the event we abandon and cease to use certain property, plant, and equipment, depreciation estimates are revised and, in most cases, depreciation expense will be accelerated to reflect the shortened useful life of the asset.
Revenue Recognition	e) Revenue Recognition We recognize revenues based on the stated shipping terms with customers when these terms are satisfied and the risks of ownership are transferred to the customers. We have an inventory management program for certain Precision Bearing Components Group customers whereby revenue is recognized when products are used by customers from consigned stock, rather than at the time of shipment. Under both circumstances, revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred, the sellers’ price is fixed and determinable and collectability is reasonably assured.
Accounts Receivable	f) Accounts Receivable Accounts receivable are recorded upon recognition of a sale of goods and ownership and risk of loss is assumed by the customer. Substantially all of our accounts receivable are due primarily from the core served markets. In establishing allowances for doubtful accounts, we perform credit evaluations of our customers, considering numerous inputs when available including the customers’ financial position, past payment history, relevant industry trends, cash flows, management capability, historical loss experience and economic conditions and prospects. Accounts receivable are written off or allowances established when considered to be uncollectible or at risk of being uncollectible, respectively.
Income Taxes	g) Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. Provision has not been made for income taxes on unremitted earnings of foreign subsidiaries as these earnings are deemed to be permanently reinvested. We recognize income tax positions that meet the more likely than not threshold and accrue interest and potential penalties related to unrecognized income tax positions which are recorded as a component of the provision (benefit) for income taxes.
Net Income Per Common Share	h) Net Income Per Common Share Basic income per share reflects reported earnings divided by the weighted average number of common shares outstanding. Diluted income per share include the effect of dilutive stock options and the respective tax benefits, unless inclusion would not be dilutive.
Share Based Compensation	i) Share Based Compensation The cost of stock options, stock awards and performance based stock units are expensed as compensation expense over the vesting periods based on the fair value at the grant date. (See Note 9 of the Notes to the Consolidated Financial Statements) We use the Black Scholes financial pricing model for our stock options, and a Monte Carlo simulation for the performance based stock units to determine the fair value as these awards as they are not traded in open markets. We account for stock awards by recognizing compensation expense ratably over the vesting period as specified in the award. Compensation expense to be recognized is based on the stock price at date of grant.
Principles of Consolidation	j) Principles of Consolidation Our consolidated financial statements include the accounts of NN, Inc. and its subsidiaries. All of our subsidiaries are 100% owned (except for RFK which we own 99.7% and our Chinese joint venture noted below) and all are included in the consolidated financial statements for the years end December 31, 2015, 2014 and 2013. All significant inter-company profits, transactions, and balances have been eliminated in consolidation. With the acquisition of Autocam Corporation (see Note 2), we acquired a 49% interest in a Chinese joint venture. This joint venture is not consolidated within the financial statements of NN, Inc. and is accounted for under the equity method (see Note 16).
Foreign Currency Translation	k) Foreign Currency Translation Assets and liabilities of our foreign subsidiaries are translated at current exchange rates, while revenue, costs and expenses are translated at average rates prevailing during each reporting period. Translation adjustments arising from the translation of foreign subsidiary financial statements are reported as a component of other comprehensive income and accumulated other comprehensive income within stockholders’ equity. In addition, transactions denominated in foreign currencies, including intercompany transactions, are initially recorded at the current exchange rate at the date of the transaction. The balances are adjusted to the current exchange rate as of each balance sheet date and as of the date when the transaction is consummated. Transaction gains or losses, excluding intercompany loan transactions, are expensed in either cost of products sold or selling, general and administrative lines in the Consolidated Statements of Operations and Comprehensive Income (Loss) as incurred and were immaterial to the years ended December 31, 2015, 2014 and 2013. Transaction gains or losses on intercompany loan transactions are recognized in the other income, net line in the Consolidated Statements of Operations and Comprehensive Income (Loss) as incurred.
Goodwill and Other Indefinite Lived Intangible Assets	l) Goodwill and Other Indefinite Lived Intangible Assets We recognize the excess of the purchase price of an acquired entity over the fair value of the net identifiable assets as goodwill. Goodwill is tested for impairment on an annual basis as of October 1 and between annual tests if a triggering event occurs. The impairment procedures are performed at the reporting unit level for the reporting units that have goodwill. In September 2011, the FASB issued a revised accounting standard, intended to reduce the cost and complexity of the annual goodwill impairment test by providing entities an option to perform a “qualitative” assessment to determine whether further impairment testing is necessary. Specifically, an entity has the option to first assess qualitative factors to determine whether it is necessary to perform the current two-step test. If an entity believes, as a result of its qualitative assessment, that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, the quantitative impairment test is required. Otherwise, no further testing is required. For the years ended, December 31, 2015 and 2014, we determined it was more appropriate to perform a full step 1 goodwill test. The decision to perform a qualitative assessment or a complete step 1 analysis is an annual decision made by management. Based on the results of the step 1 analysis fair value of the reporting units exceeded the carrying value of the reporting units at December 31, 2015 and 2014. If the qualitative assessment indicates it is more likely than not that the fair value is less than the carrying value, GAAP prescribes a two-step process for testing for goodwill impairments. The first step is to determine if the carrying value of the reporting unit with goodwill is less than the related fair value of the reporting unit. We consider three main approaches to value (cost, market and income) the fair value of the reporting unit and market based multiples of earning and sales methods obtained from a grouping of comparable publicly trading companies. We believe this methodology of valuation is consistent with how market participants would value reporting units. The discount rate and market based multiples used are specifically developed for the unit tested regarding the level of risk and end markets served. Even though we do use other observable inputs (Level 2 inputs) the calculation of fair value for goodwill would be most consistent with Level 3 inputs. If the carrying value of the reporting unit including goodwill is less than fair value of the reporting unit, the goodwill is not considered impaired. If the carrying value is greater than fair value then the potential for impairment of goodwill exists. The potential impairment is determined by allocating the fair value of the reporting unit among the assets and liabilities based on a purchase price allocation methodology as if the reporting unit was acquired in a business combination. The fair value of the goodwill is implied from this allocation and compared to the carrying value with an impairment loss recognized if the carrying value is greater than the implied fair value. We base our fair value estimates, in large part, on management business plans and projected financial information which are subject to a high degree of management judgment and complexity. Actual results may differ from projections and the differences may be material.
Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed Of	m) Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed Of Long-lived tangible and intangible assets subject to amortization are tested for recoverability when changes in circumstances indicate the carrying value of these assets may not be recoverable. A test for recoverability is also performed when management has committed to a plan to dispose of a reporting unit or asset group. Assets to be held and used are tested for recoverability when indications of impairment are evident. Recoverability of a long-lived tangible and intangible asset is evaluated by comparing its carrying value to the future estimated undiscounted cash flows expected to be generated by the asset or asset group. If the asset is not recoverable the asset is considered impaired and adjusted to fair value which is then depreciated/amortized over its remaining useful life. Assets to be disposed of are carried at the lesser of carrying value or fair value less costs of disposal.
Use of Estimates in the Preparation of Financial Statements	n) Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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. Actual results could differ from those estimates.
Fair Value Measurements	o) Fair Value Measurements Fair value principles prioritize valuation inputs across three broad levels. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based on the assumptions used to measure assets and liabilities at fair value. An asset or liability’s classification within the various levels is determined based on the lowest level input that is significant to the fair value measurement.
Recently Issued Accounting Standards	p) Recently Issued Accounting Standards In May 2014, the Financial Accounting Standards Board (“FASB”) and International Accounting Standards Board jointly issued new principles-based accounting guidance for revenue recognition that will supersede virtually all existing revenue guidance, Revenue from Contracts with Customers (Topic 606). The core principle of this guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. To achieve the core principle, the guidance establishes the following five steps: 1) identify the contract(s) with a customer, 2) identify the performance obligation in the contract, 3) determine the transaction price, 4) allocate the transaction price to the performance obligations in the contract, and 5) recognize revenue when (or as) the entity satisfies a performance obligation. The guidance also details the accounting treatment for costs to obtain or fulfill a contract. Lastly, disclosure requirements have been enhanced to provide sufficient information to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. This guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early application is not permitted. We are currently evaluating the impact this new guidance is expected to have on our financial position or results of operations and related disclosures. In August 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40), which provides guidance about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. The amendments require management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles that are currently in U.S. auditing standards. Specifically, the amendments (1) provide a definition of the term “substantial doubt”, (2) require an evaluation every reporting period including interim periods, (3) provide principles for considering the mitigating effect of management’s plans, (4) require certain disclosures when substantial doubt is alleviated as a result of consideration of management’s plans, (5) require an express statement and other disclosures when substantial doubt is not alleviated, and (6) require an assessment for a period of one year after the date that the financial statements are issued (or available to be issued). ASU 2014-15 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period and early adoption is permitted. We are currently evaluating the impact this new guidance is expected to have on our financial position or results of operations and related disclosures. In April 2015, the FASB issued 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 No. 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. ASU 2015-03 is effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period and early adoption is permitted for financial statements that have not yet been previously issued. In accordance with ASU No. 2015-03, companies should apply the new guidance on a retrospective basis, wherein the balance sheet of each individual period presented should be adjusted to reflect the period-specific effects of applying the new guidance. Upon transition, an entity is required to comply with the applicable disclosures for a change in an accounting principle. Adoption is not expected to have a material effect on our consolidated financial statements, but will affect balance sheet classification. We are currently evaluating the impact this new guidance is expected to have on our financial position or results of operations and related disclosures. In July 2015, the FASB issued 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 guidance applies only to inventories for which cost is determined by methods other than last-in first-out (“LIFO”) and the retail inventory method. The guidance in ASU No. 2015-11 is effective for periods beginning after December 15, 2016 and early adoption is permitted. We are currently evaluating the impact, if any, adoption will have on its financial position and results of operations. In July 2015, the FASB issued ASR No AUS 2015-12, Plan Accounting: Defined Benefit Pension Plans (Topic 960), Defined Contribution Pension Plans (Topic 962), Health and Welfare Benefit Plans (Topic 965), (Part I) Fully Benefit-Responsive Investment Contracts, (Part II) Plan Investment Disclosures, (Part III) Measurement Date Practical Expedient (consensuses of the FASB Emerging Issue Task Force) (ASU 2015-12). The standard eliminates requirements that employment benefit plans measure the fair value of fully benefit-responsive investment contracts (FBRICs) and provide the related fair value disclosures. As a result. FBRICs are measured, presented and disclosed only at contract value. Also, plans will be required to disaggregate their investments measured using fair value by general type, either on the face of the financial statements or in the notes, and self-directed brokerage fair value of investments by general type or individual investments equal to or greater than 5% of net assets available for benefits. In addition, a plan with a fiscal year end that doesn’t coincide with the end of a calendar month is allowed to measure its investments and investment-related accounting using month end closest to its fiscal year end. The new guidance for FBRICs and plan investment disclosures should be applied retrospectively, the measurement date practical expedient should be applied prospectively. The guidance is effective for fiscal years beginning after December 15, 2015. Earlier application is permitted. We are currently evaluating the impact this new guidance is expected to have on our financial position or results of operations and related disclosures. In September 2015, the FASB issued 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, an acquirer will recognize a measurement-period adjustment during the period in which it determines 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. The guidance is effective for fiscal years, including interim periods within fiscal years beginning after December 15, 2015. Early adoption is permitted. In November 2015, The FAS issues ASU No. 2015-17, Income Taxes (Topic 740) - Balance Sheet Classification of Deferred Taxes (“ASU 2017-17”). Companies are required to classify all deferred tax assets and liabilities as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. Also, companies will no longer allocation valuation allowances between current and noncurrent deferred tax assets because those allowances also will be classified as noncurrent. Since early adoption of the guidance is permitted, companies can start applying it in interim and annual financial statements that have not yet been issued. The guidance is effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. We are currently evaluating the impact this new guidance is expected to have on our financial position or results of operations and related disclosures. In February 2016, the FASB issued a new lease accounting standard. The key objective of the new standard is to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Lessees will need to recognize a right-of-use asset and a lease liability for virtually all of their leases (other than leases that meet the definition of a short-term lease). For income statement purposes, a dual model has been retained, with leases to be designated as operating leases or finance leases. Expenses will be recognized on a straight-line basis for operating leases, and a front-loaded basis for finance leases. For public entities, the new standard is effective for periods beginning after December 15, 2018, with early adoption permitted. The new standard must be adopted using a modified retrospective transition, and provides for certain practical expedients. The Company is currently evaluating the impact of the new standard on its financial position, results of operations and cash flows.
Business Combinations	q) Business Combinations We allocate the total purchase price of the acquired tangible and intangible assets acquired and liabilities assumed based on their estimated fair values as of the business combination date, with the excess purchase price recorded as goodwill. The purchase price allocation process required us to use significant estimates and assumptions, including fair value estimates, as of the business combination date. Although we believe the assumptions and estimates we have made are reasonable and appropriate, they are based in part on historical experience and information obtained from management of the acquired company, in part based on valuation models that incorporate projections of expected future cash flows and operating plans and are inherently uncertain. Valuations are performed by management or third party valuation specialists under management’s supervision. In determining the fair value of assets acquired and liabilities assumed in business combinations, as appropriate, we may use one of the following recognized valuation methods: the income approach (including discounted cash flows from relief from royalty and excess earnings model), the market approach and/or the replacement cost approach. Examples of significant estimates used to value certain intangible assets acquired include but are not limited to: • sales volume, pricing and future cash flows of the business overall; • future expected cash flows from customer relationships, and other identifiable intangible assets, including future price levels, rates of increase in revenue and appropriate attrition rate; • the acquired company’s brand and competitive position, royalty rate quantum, as well as assumptions about the period of time the acquired brand will continue to benefit to the combined company’s product portfolio; and • cost of capital, risk-adjusted discount rates and income tax rates. However, different assumptions regarding projected performance and other factors associated with the acquired assets may affect the amount recorded under each type of assets and liabilities, mainly between property plant and equipment, intangibles assets, goodwill and deferred income tax liabilities and subsequent assessment could result in future impairment charges. The purchase price allocation process also entails us to refine these estimates over a measurement period not to exceed one year to reflect new information obtained surrounding facts and circumstances existing at acquisition date.
