We intend to adopt the standard utilizing the modified retrospective transition method. Under this transition method, we will recognize the cumulative effect of initially applying the new standard as an adjustment to the opening balance of retained earnings as of January 1, 2018, and will apply the new standard beginning with the most current period presented to contracts that are not completed at the date of initial application. We continue to evaluate the adoption method throughout each phase of implementation. While our ability to adopt the standard using the modified retrospective method depends on system readiness and completing our analysis of information necessary to present required footnote disclosures in the consolidated financial statements, the implementation project remains on schedule. We have completed a diagnostic accounting assessment, including an analysis of a representative sample of contracts, to identify areas that will be most significantly impacted by implementation of the new standard. We have also completed initial training to educate contract managers of the technical aspects of the new standard. We are in the process of concluding on and documenting our assessments related to the standard as well as potential system and procedural changes. We are evaluating the impact the new standard will have on our financial condition, results of operations and cash flows. We expect to complete our final evaluation of the impact of adopting the new standard during 2017.

We continue to utilize the Senior Secured Revolver for daily working capital needs. We assumed certain foreign credit facilities as part of the Autocam acquisition. 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 used to fund working capital and equipment purchases in those countries. Our 2016 Annual Report includes descriptions of these foreign credit facilities.

Shared-Based Compensation	Note 9. Shared-Based Compensation The following table lists the components of share-based compensation expense for the three-month and nine-month periods ended September 30, 2017 and 2016, by type of award. Three Months Ended Nine Months Ended September 30, September 30, 2017 2016 2017 2016 Stock options $ 527 $ 185 $ 1,102 $ 679 Restricted stock 773 425 1,628 2,120 Performance share units 467 294 1,255 760 Share-based compensation $ 1,767 $ 904 $ 3,985 $ 3,559 Prior to the sale of the PBC business, our board of directors approved the acceleration of vesting of share-based awards to 19 members of PBC executive management in recognition of their service to the Company. The vesting date was accelerated to August 17, 2017, and the term was changed to two years for 58,094 option awards. The vesting date for 25,564 restricted stock awards was accelerated to August 17, 2017. We accounted for the acceleration of vesting as a modification of share-based awards. Accordingly, we recognized in discontinued operations approximately $0.8 million of incremental share-based compensation expense. Stock Options During the nine months ended September 30, 2017, we granted 125,700 option awards to officers and certain other key employees. The weighted average grant date fair value of options granted during the nine months ended September 30, 2017, was $11.84 per share. The fair value of these options cannot be determined by market value because the options are not traded in an open market. Accordingly, we utilized the Black Scholes financial pricing model to estimate the fair value. The following table shows the weighted average assumptions relevant to determining the fair value of the 2017 stock option grants. 2017 Expected term 6 years Risk free interest rate 2.03 % Dividend yield 1.16 % Expected volatility 56.56 % Expected forfeiture rate 3.00 % The following table provides a reconciliation of option activity for the nine months ended September 30, 2017. Weighted- Weighted- Average Average Exercise Remaining Aggregate Price Contractual Intrinsic Options Shares (000) (per share) Term (years) Value Outstanding at January 1, 2017 897 $ 12.22 Granted 126 24.20 Exercised (250 ) 11.79 Forfeited or expired (6 ) 7.72 Outstanding at September 30, 2017 767 $ 14.32 6.5 $ 11,246 (1) Exercisable at September 30, 2017 583 $ 12.71 5.7 $ 9,500 (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 September 30, 2017. Restricted Stock During the nine months ended September 30, 2017, we granted 85,393 restricted stock awards to non-executive pro-rata non-executive Performance Share Units During the nine months ended September 30, 2017, we granted 98,618 performance share units to officers and certain other key employees. The performance share units granted will be satisfied in the form of shares of common stock during 2020 if certain performance and/or market conditions are met. We recognize the compensation expense over the three-year period in which the performance and market conditions are measured. We determined the fair value per share of the performance share units issued by using the grant date closing price of our common stock for the units with a performance condition, or $24.20, and a Monte Carlo valuation model for the units that have a market condition, or $29.84.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Note 10. Income Taxes Our effective tax rate from continuing operations was 26% and 31% for the three-month and nine-month periods ended September 30, 2017, respectively, and 93% and 51% for the three-month and nine-month periods ended September 30, 2016, respectively. The loss on extinguishment of Senior Notes impacted the 2017 tax rate and was treated as a discrete item during the second quarter of 2017. The 2016 effective rate was impacted by changes in forecasted income and loss and driven by the application of the three- and nine-month results against the permanent book to tax differences. The effective tax rates for 2017 and 2016 differ from the U.S. federal statutory tax rate of 35% due primarily to earnings outside the United States that are indefinitely reinvested and taxed at rates lower than the U.S. federal statutory rate. Management believes that it is reasonably possible that the amount of unrecognized income tax benefits and interest may decrease during the next 12 months by approximately $0.6 million related to the expiration of the statutes of limitations, of which $0.5 million would reduce income tax expense. During the third quarter of 2017, the Internal Revenue Service commenced an examination of the federal tax return for the pre-acquisition

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 11. Commitments and Contingencies Brazil ICMS Tax Matter Prior to the Autocam acquisition, Autocam’s Brazilian subsidiary received notification from the Brazilian tax authorities regarding ICMS (state value added tax or VAT) tax credits claimed on intermediary materials (tooling and perishable items) used in the manufacturing process. The Brazilian 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 Brazilian tax authority arguing, among other matters, that it should qualify for an ICMS tax credit, contending that the intermediary materials are directly related to the manufacturing process. We believe that we have substantial legal and factual defenses, and we plan to defend our interests in this matter vigorously. While we believe a loss is not probable, we estimate the range of possible losses related to this assessment is from $0 to $6.0 million. No amount was accrued at September 30, 2017, for this matter. There was no material change in the status of this matter from December 31, 2016 to September 30, 2017. 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 relating to the Autocam acquisition. Management believes the indemnification would include amounts owed for the tax, interest and penalties related to this 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.

Equity Method Investments and Joint Ventures [Abstract]
Investment in Joint Venture	Note 12. Investment in Joint Venture We own a 49% investment in a joint venture located in Wuxi, China, with an unrelated entity called Wuxi Weifu Autocam Precision Machinery Company, Ltd. (the “JV”). The JV is jointly controlled and managed, and we account for it under the equity method. The following table summarizes activity related to our investment in the JV for the nine months ended September 30, 2017. Balance as of December 31, 2016 $ 36,008 Our share of cumulative earnings 4,481 Dividends declared and paid by joint venture (4,156 ) Accretion of basis difference from purchase accounting (342 ) Foreign currency translation gain 1,748 Balance as of September 30, 2017 $ 37,739 The following table summarizes balance sheet information of the JV itself.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 13. Fair Value Measurements Fair value is an exit price representing the expected amount that an entity would receive to sell an asset or pay to transfer a liability in an orderly transaction with market participants at the measurement date. We followed consistent methods and assumptions to estimate fair values as more fully described in the 2016 Annual Report. Our financial instruments that are subject to fair value disclosure consist of cash and cash equivalents, accounts receivable, accounts payable, derivatives and long-term debt. As of September 30, 2017, the carrying values of these financial instruments approximated fair value. The fair value of floating-rate debt approximates the carrying amount because the interest rates paid are based on short-term maturities. As of September 30, 2017, we had no fixed-rate debt outstanding. 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. The following table summarizes assets and liabilities measured at fair value on a recurring basis for the interest rate swap derivative financial instrument: Fair Value Measurements at September 30, 2017 Description September 30, Quoted Prices in Significant Other Significant Derivative asset - current $ 10 — $ 10 — Derivative asset - noncurrent — — — — Derivative liability - current (1,479 ) — (1,479 ) — Derivative liability - noncurrent — — — — $ (1,469 ) — $ (1,469 ) — Fair Value Measurements at December 31, 2016 Description December 31, Quoted Prices in Significant Other Significant Derivative asset - current $ 69 $ — $ 69 $ — Derivative asset - noncurrent 6 — 6 — Derivative liability - current (1,903 ) — (1,903 ) — Derivative liability - noncurrent (1,028 ) — (1,028 ) — $ (2,856 ) $ — $ (2,856 ) $ — 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 interest rate swaps to exchange the difference between fixed and variable interest amounts. The inputs for determining fair value of the interest rate swap are classified as Level 2 inputs. 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. Counterparties to these derivative contracts are highly rated financial institutions which management believes carry only a minimal risk of nonperformance. We have elected to present the derivative contracts on a gross basis in the Condensed Consolidated Balance Sheets included within other current assets, other non-current non-current As of September 30, 2017, we had no gains or losses in accumulated other comprehensive income related to the interest rate swap. Additionally, during the nine months ended September 30, 2016, when the interest rate swap was accounted for in accordance with hedge accounting, the periodic settlements and related reclassification of other comprehensive income was $1.4 million of net hedging losses on the interest rate swap in the interest expense line on the Condensed Consolidated Statements of Operations and Comprehensive Income. The “Derivative loss (gain) on change in interest rate swap fair value” line on the Condensed Consolidated Statements of Operations and Comprehensive Income includes interest rate swap settlements of $0.3 million and $1.3 million for the three-month and nine-month periods ended September 30, 2017, and $0.6 million for the three-month and nine-month periods ended September 30, 2016. Effective October 27, 2017, we terminated our interest rate swap with a cash payment of $1.3 million. Therefore, we classified all amounts related to the interest rate swap as current assets and current liabilities on our balance sheet as of September 30, 2017.

Restructuring and Integration	Note 14. Restructuring and Integration We recognized restructuring and integration costs totaling $0.3 million and $0.4 million in the three-month and nine-month periods ended September 30, 2017. We recognized restructuring and integration costs totaling $0.6 million and $4.9 million in the three-month and nine-month periods ended September 30, 2016. Within APC, certain restructuring programs that included the closure of one facility, the Wheeling Plant, resulted in a charge of $0.3 million and $0.4 million for the three-month and nine-month periods ended September 30, 2017, and $0.3 million and $3.9 million for the three-month and nine-month periods ended September 30, 2016. Within PEP, initiatives resulted in integration, site closure and employee costs of $0.3 million and $1.0 million for the three-month and nine-month periods ended September 30, 2016. There were no charges in the three-month and nine-month periods ended September 30, 2017. The following table summarizes restructuring and integration activity related to actions incurred for the three-month and nine-month periods ended September 30, 2017 and 2016.

Future filings will include updates to these activities along with a reconciliation of beginning and ending liabilities. We expect to pay $1.0 million of the reserve balance remaining at September 30, 2017, within the next twelve months. The remaining reserve of $0.2 million is expected to be paid in 2018 and 2019.

Recently Issued Accounting Standards	Issuance of New Accounting Standards Revenue Recognition. pre-and The standard will be effective for us beginning January 1, 2018. We intend to adopt the standard utilizing the modified retrospective transition method. Under this transition method, we will recognize the cumulative effect of initially applying the new standard as an adjustment to the opening balance of retained earnings as of January 1, 2018, and will apply the new standard beginning with the most current period presented to contracts that are not completed at the date of initial application. We continue to evaluate the adoption method throughout each phase of implementation. While our ability to adopt the standard using the modified retrospective method depends on system readiness and completing our analysis of information necessary to present required footnote disclosures in the consolidated financial statements, the implementation project remains on schedule. We have completed a diagnostic accounting assessment, including an analysis of a representative sample of contracts, to identify areas that will be most significantly impacted by implementation of the new standard. We have also completed initial training to educate contract managers of the technical aspects of the new standard. We are in the process of concluding on and documenting our assessments related to the standard as well as potential system and procedural changes. We are evaluating the impact the new standard will have on our financial condition, results of operations and cash flows.
