Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation TriMas Corporation ("TriMas" or the "Company"), and its consolidated subsidiaries, is a global manufacturer and distributor of products for commercial, industrial and consumer markets. The Company is principally engaged in the following reportable segments with diverse products and market channels: Packaging, Aerospace, Energy and Engineered Components. See Note 11 , " Segment Information ," for further information on each of the Company's reportable segments. On June 30, 2015, the Company completed the previously announced spin-off of its Cequent businesses, creating a new independent publicly traded company, Horizon Global Corporation ("Horizon"). In addition, on June 30, 2015, immediately prior to the effective time of the spin-off, Horizon paid a cash distribution to the Company of $214.5 million using the proceeds of its new debt financing arrangement and cash on hand. Consistent with previous estimates, the Company incurred approximately $30 million of one-time, pre-tax costs associated with the spin-off, of which approximately $29 million was incurred during 2015. These costs primarily related to financing, legal, tax and accounting services rendered by third parties. Of the $30 million in costs, approximately $18 million was included in income (loss) from discontinued operations, $9 million was capitalized as deferred financing fees associated with Horizon's debt issuance coincident with the spin-off and was included in the balance sheet of the discontinued operations and approximately $3 million relates to fees associated with the Company's refinancing of long-term debt, of which approximately $2 million was included in income from continuing operations as debt financing and extinguishment costs and approximately $1 million was capitalized as deferred financing fees in the accompanying consolidated balance sheet. The financial position, results of operations and cash flows of the Cequent businesses are reflected as discontinued operations for all periods presented through the date of the spin-off. See Note 3 , " Discontinued Operations ," for further details regarding the spin-off. The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries and, in the opinion of management, contain all adjustments, including adjustments of a normal and recurring nature, necessary for a fair presentation of financial position and results of operations. Results of operations for interim periods are not necessarily indicative of results for the full year. The accompanying consolidated financial statements and notes thereto should be read in conjunction with the Company's 2014 Annual Report on Form 10-K.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements In September 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2015-16, "Business Combinations (Topic 805): Simplifying the Accounting for Measurement - Period Adjustments" ("ASU 2015-16"). ASU 2015-16 requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The effect on earnings of changes in depreciation, amortization or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date must be recorded in the reporting period in which the adjustment amounts are determined rather than retrospectively. Additionally, an entity is required to present separately on the face of the income statement or disclose in the notes to the financial statements the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU 2015-16 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015, with early adoption permitted. The Company is in the process of assessing the impact of the adoption of ASU 2015-16 on its consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, "Inventory (Topic 330): Simplifying the Measurement of Inventory" ("ASU 2015-11"). ASU 2015-11 requires an entity to measure inventory at the lower of cost and net realizable value, thereby simplifying the current guidance under which an entity must measure inventory at the lower of cost or market. The ASU defines net realizable value as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. ASU 2015-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016 and is to be applied prospectively with early adoption permitted. The Company is in the process of assessing the impact of adoption of ASU 2015-11 on its consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, "Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs" ("ASU 2015-03"). ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. Given the absence of authoritative guidance within ASU 2015-03 for debt issuance costs related to line-of-credit arrangements, in August 2015, the FASB issued ASU 2015-15, "Interest - Imputation of Interest (Subtopic 835-30) - Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements," which clarifies ASU 2015-03 by stating that the staff of the Securities and Exchange Commission ("SEC") would not object to an entity deferring and presenting debt issuance costs associated with line-of-credit arrangements as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. ASU 2015-03 is currently effective for fiscal years, and interim periods within those years, beginning after December 15, 2015, with early adoption permitted. The Company is in the process of assessing the impact of the adoption of ASU 2015-03 on its consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)" ("ASU 2014-09"). ASU 2014-09 requires that an entity recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. ASU 2014-09 was originally effective for fiscal years, and interim periods within those years, beginning on or after December 15, 2016. In August 2015, the FASB issued ASU 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date" ("ASU 2015-14"), which defers ASU 2014-09 by one year, making it effective for annual reporting periods beginning on or after December 15, 2017 while also providing for early adoption, but not before the original effective date. The Company is in the process of assessing the impact of the adoption of ASU 2014-09 on its consolidated financial statements.

Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]	. Discontinued Operations Spin-off of the Cequent businesses On June 30, 2015, the Company completed the previously announced spin-off of its Cequent businesses (comprised of the former Cequent Americas and Cequent Asia Pacific Europe Africa ("Cequent APEA") reportable segments), creating a new independent publicly traded company, Horizon, through the distribution of 100% of the Company's interest in Horizon to holders of the Company's common stock. On June 30, 2015, each of the Company's shareholders of record as of the close of business on the record date of June 25, 2015 received two shares of Horizon common stock for every five shares of TriMas common stock held. In addition, on June 30, 2015, immediately prior to the effective time of the spin-off, Horizon entered into a new debt financing arrangement and used the proceeds to make a cash distribution of $214.5 million to the Company. The Cequent businesses are presented as discontinued operations in the Company's consolidated balance sheet, the consolidated statements of income and cash flows for all periods presented.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets In connection with the Company’s reporting, forecasting and analysis of the results of operations during the third quarter of 2015, the Company determined that there were indicators of a decline in fair value of the Company’s Energy and engine products reporting units due to a significant decline in profitability levels, which also may indicate a potential impairment of the recorded goodwill and/or indefinite-lived intangible assets. In addition, the Company’s stock price and resulting market capitalization declined approximately 30% during the third quarter of 2015, which management believes is partially due to the decline in profitability of the aforementioned two reporting units. The Company considers the reduction in total Company market capitalization, which is a significant input to estimated total Company fair value, as an indicator that the fair value of the Energy and engine products reporting units, and/or other reporting units, may be less than the carrying value. In September 2015, the Company announced a broadly-focused financial improvement plan, to be implemented over the next few quarters and expected to result in improved operational efficiencies, profitability, and cash flow. The plan includes significant cost savings actions within the Energy and engine products reporting units, the impact of which the Company is evaluating in connection with an estimate of fair value. Given this fact pattern and indicators of potential impairment, the Company determined it would perform an impairment analysis of each of the Company’s reporting units and indefinite-lived trademarks/tradenames, along with a comparison of the estimated aggregate fair value of all reporting units to the Company’s market capitalization. As the financial improvement plan was not announced until mid-September and is an important input to the estimation of the fair value of Company’s reporting units, and the market capitalization continued to be volatile throughout August and September, there was inadequate time within the third quarter to complete the impairment analysis. The Company expects to complete the testing during the fourth quarter of 2015.

Debt Disclosure [Abstract]
Long-term debt	Long-term Debt The Company's long-term debt consists of the following: September 30, December 31, (dollars in thousands) Credit Agreement $ 390,120 $ 559,530 Receivables facility and other 69,300 79,040 459,420 638,570 Less: Current maturities, long-term debt 13,860 23,400 Long-term debt $ 445,560 $ 615,170 Credit Agreement During the second quarter of 2015, the Company amended its credit agreement (the "Credit Agreement"), pursuant to which the Company was able to extend maturities and resize its credit facilities following the spin-off of the Cequent businesses. The cash distribution to the Company from Horizon was used to reduce the outstanding borrowings under the previous credit agreement. The Credit Agreement consists of a $500.0 million senior secured revolving credit facility, which permits borrowings denominated in specific foreign currencies ("Foreign Currency Loans"), subject to a $75.0 million sub limit, which matures on June 30, 2020 and is subject to interest at London Interbank Offered Rates ("LIBOR") plus 1.75%, and a $275.0 million senior secured term loan A facility ("Term Loan A Facility"), which matures on June 30, 2020 and is subject to interest at LIBOR plus 1.75%. The interest rate spread is based upon the leverage ratio, as defined, as of the most recent determination date. The Credit Agreement also provides incremental term loan and/or revolving credit facility commitments in an amount not to exceed the greater of $300.0 million and an amount such that, after giving effect to such incremental commitments and the incurrence of any other indebtedness substantially simultaneously with the making of such commitments, the senior secured net leverage ratio, as defined, is no greater than 2.50 to 1.00. The terms and conditions of any incremental term loan and/or revolving credit facility commitments must be no more favorable than the existing credit facility. The Company may be required to prepay a portion of its Term Loan A Facility in an amount equal to a percentage of the Company's excess cash flow, as defined, with such percentage based on the Company's leverage ratio, as defined. As of September 30, 2015 , no amounts are due under this provision. The Company is also able to issue letters of credit, not to exceed $40.0 million in aggregate, against its revolving credit facility commitments. At September 30, 2015 and December 31, 2014 , the Company had letters of credit of approximately $22.4 million and $21.9 million , respectively, issued and outstanding. At September 30, 2015 , the Company had approximately $115.1 million outstanding under its revolving credit facility and had $362.5 million potentially available after giving effect to approximately $22.4 million of letters of credit issued and outstanding. At December 31, 2014 , the Company had approximately $118.1 million outstanding under its revolving credit facility and had $435.0 million potentially available after giving effect to approximately $21.9 million of letters of credit issued and outstanding. However, including availability under its accounts receivable facility and after consideration of leverage restrictions contained in the Credit Agreement, the Company had $107.3 million and $192.0 million at September 30, 2015 and December 31, 2014 , respectively, of borrowing capacity available for general corporate purposes. Principal payments required under the Credit Agreement for the Term Loan A Facility are approximately $3.4 million due each fiscal quarter from December 2015 through September 2018 and approximately $5.2 million due each fiscal quarter from December 2018 through March 2020, with final payment of $202.8 million due on June 30, 2020. The debt under the Credit Agreement is an obligation of the Company and certain of its domestic subsidiaries and is secured by substantially all of the assets of such parties. Borrowings under the $75.0 million foreign currency sub limit of the $500.0 million senior secured revolving credit facility are secured by a pledge of the assets of the foreign subsidiary borrowers that are a party to the agreement. The Credit Agreement also contains various negative and affirmative covenants and other requirements affecting the Company and its subsidiaries, including restrictions on the incurrence of debt, liens, mergers, investments, loans, advances, guarantee obligations, acquisitions, assets dispositions, sale-leaseback transactions, hedging agreements, dividends and other restricted payments, transactions with affiliates, restrictive agreements and amendments to charters, bylaws, and other material documents. The terms of the Credit Agreement also require the Company and its subsidiaries to meet certain restrictive financial covenants and ratios computed quarterly, including a maximum leverage ratio (total consolidated indebtedness plus outstanding amounts under the accounts receivable securitization facility over consolidated EBITDA, as defined) and a minimum interest expense coverage ratio (consolidated EBITDA, as defined, over cash interest expense, as defined). At September 30, 2015 , the Company was in compliance with its financial covenants contained in the Credit Agreement. The Company incurred approximately $1.8 million in fees to complete the amendment of the Credit Agreement, of which approximately $1.4 million was capitalized as deferred financing fees and $0.4 million was recorded as debt financing fees in the accompanying consolidated statement of income during the nine months ended September 30, 2015. The Company also recorded non-cash debt extinguishment costs of $1.5 million related to the write-off of deferred financing fees associated with the previous credit facilities. As of September 30, 2015 and December 31, 2014 , the Company's Term Loan A Facility traded at approximately 95.5% and 99.5% of par value and the Company's revolving credit facility traded at approximately 94.2% and 99.2% of par value, respectively. The valuations of the Credit Agreement were determined based on Level 2 inputs under the fair value hierarchy, as defined. Receivables Facility The Company is a party to an accounts receivable facility through TSPC, Inc. ("TSPC"), a wholly-owned subsidiary, to sell trade accounts receivable of substantially all of the Company's domestic business operations. During the second quarter of 2015, the Company amended the facility to remove the Cequent businesses and to reduce the committed funding from $105.0 million to $75.0 million , with no other significant changes to the facility. Under this facility, TSPC, from time to time, may sell an undivided fractional ownership interest in the pool of receivables up to approximately $75.0 million to a third party multi-seller receivables funding company. The net amount financed under the facility is less than the face amount of accounts receivable by an amount that approximates the purchaser's financing costs. The cost of funds under this facility consisted of a 3-month LIBOR-based rate plus a usage fee of 1.00% and 1.15% as of September 30, 2015 and 2014 , respectively, and a fee on the unused portion of the facility of 0.35% as of September 30, 2015 and 2014 . The Company had approximately $69.0 million and $78.7 million outstanding under the facility as of September 30, 2015 and December 31, 2014 , respectively. No amounts were available but not utilized as of September 30, 2015 . As of December 31, 2014 , approximately $1.6 million was available but not utilized. Aggregate costs incurred under the facility were approximately $0.2 million and $0.3 million for the three months ended September 30, 2015 and 2014 , respectively, and $0.7 million and $1.0 million for the nine months ended September 30, 2015 and 2014 , respectively, and are included in interest expense in the accompanying consolidated statement of income. The facility expires on October 16, 2018 . The cost of funds fees incurred are determined by calculating the estimated present value of the receivables sold compared to their carrying amount. The estimated present value factor is based on historical collection experience and a discount rate based on a 3-month LIBOR-based rate plus the usage fee discussed above and is computed in accordance with the terms of the agreement. As of September 30, 2015 , the cost of funds under the facility was based on an average liquidation period of the portfolio of approximately 1.7 months and an average discount rate of 1.8% .

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments The Company utilizes interest rate swap agreements to fix the LIBOR-based variable portion of the interest rate on its long term debt. Terms of the interest rate swap agreements require the Company to receive a variable interest rate and pay a fixed interest rate. As of September 30, 2015 , the Company had interest rate swap agreements in place that hedge a notional value of debt ranging from approximately $251.5 million to approximately $192.7 million and amortize consistent with future debt principal payments. The interest rate swap agreements establish fixed interest rates in a range of 0.74% to 2.68% with various expiration terms extending to June 30, 2020. At inception, the interest rate swaps were and continue to be designated as cash flow hedges. As of September 30, 2015 and December 31, 2014 , the fair value carrying amount of the Company's derivative instruments are recorded as follows: Asset / (Liability) Derivatives Balance Sheet Caption September 30, December 31, (dollars in thousands) Derivatives designated as hedging instruments Interest rate swaps Other assets $ 90 $ 1,270 Interest rate swaps Accrued liabilities (510 ) (180 ) Interest rate swaps Other long-term liabilities (4,470 ) — Total derivatives designated as hedging instruments $ (4,890 ) $ 1,090 The following table summarizes the income (loss) recognized in accumulated other comprehensive income ("AOCI"), the amounts reclassified from AOCI into earnings and the amounts recognized directly into earnings as of September 30, 2015 and December 31, 2014 , and for the three and nine months ended September 30, 2015 and 2014 : Amount of Income (Loss) Recognized Amount of Loss Reclassified Three months ended Nine months ended As of September 30, 2015 As of December 31, 2014 Location of Loss Reclassified from AOCI into Earnings (Effective Portion) 2015 2014 2015 2014 (dollars in thousands) (dollars in thousands) Derivatives designated as hedging instruments Interest rate swaps $ (3,030 ) $ 680 Interest expense $ (210 ) $ — $ (210 ) $ — Income (loss) from discontinued operations $ — $ (240 ) $ (440 ) $ (730 ) Over the next 12 months , the Company expects to reclassify approximately $0.5 million of pre-tax deferred losses from AOCI to interest expense as the related interest payments for the designated interest rate swaps are funded. The fair value of the Company's derivatives are estimated using an income approach based on valuation techniques to convert future amounts to a single, discounted amount. Estimates of the fair value of the Company's interest rate swaps use observable inputs such as interest rate yield curves.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Asbestos As of September 30, 2015 , the Company was a party to 1,056 pending cases involving an aggregate of 6,297 claimants alleging personal injury from exposure to asbestos containing materials formerly used in gaskets (both encapsulated and otherwise) manufactured or distributed by certain of the Company's subsidiaries for use primarily in the petrochemical refining and exploration industries. The following chart summarizes the number of claimants, number of claims filed, number of claims dismissed, number of claims settled, the average settlement amount per claim and the total defense costs, exclusive of amounts reimbursed under the Company's primary insurance, at the applicable date and for the applicable periods: Claims pending at beginning of period Claims filed during period Claims dismissed during period Claims settled during period Average settlement amount per claim during period Total defense costs during period Fiscal Year Ended December 31, 2014 7,975 210 155 38 $ 18,734 $ 2,800,000 Nine Months Ended September 30, 2015 7,992 221 1,897 19 $ 10,318 $ 2,326,180 In addition, the Company acquired various companies to distribute its products that had distributed gaskets of other manufacturers prior to acquisition. The Company believes that many of its pending cases relate to locations at which none of its gaskets were distributed or used. The Company may be subjected to significant additional asbestos-related claims in the future, the cost of settling cases in which product identification can be made may increase, and the Company may be subjected to further claims in respect of the former activities of its acquired gasket distributors. The Company is unable to make a meaningful statement concerning the monetary claims made in the asbestos cases given that, among other things, claims may be initially made in some jurisdictions without specifying the amount sought or by simply stating the requisite or maximum permissible monetary relief, and may be amended to alter the amount sought. The large majority of claims do not specify the amount sought. Of the 6,297 claims pending at September 30, 2015 , 139 set forth specific amounts of damages (other than those stating the statutory minimum or maximum). Below is a breakdown of the amount sought for those claims seeking specific amounts: Compensatory & Punitive Compensatory Only Punitive Only Range of damages sought (in millions) $0.0 to $5.0 $5.0 to $10.0 $10.0+ $0.0 to $0.6 $0.6 to $5.0 $5.0+ $0.0 to $2.5 $2.5 to $5.0 $5.0+ Number of claims 67 43 29 17 52 70 136 2 1 In addition, relatively few of the claims have reached the discovery stage and even fewer claims have gone past the discovery stage. Total settlement costs (exclusive of defense costs) for all asbestos-related cases, some of which were filed over 20 years ago, have been approximately $7.5 million . All relief sought in the asbestos cases is monetary in nature. To date, approximately 40% of the Company's costs related to settlement and defense of asbestos litigation have been covered by its primary insurance. Effective February 14, 2006, the Company entered into a coverage-in-place agreement with its first level excess carriers regarding the coverage to be provided to the Company for asbestos-related claims when the primary insurance is exhausted. The coverage-in-place agreement makes asbestos defense costs and indemnity coverage available to the Company that might otherwise be disputed by the carriers and provides a methodology for the administration of such expenses. Nonetheless, the Company believes it is likely there will be a period within the next one or two years, prior to the commencement of coverage under this agreement and following exhaustion of the Company's primary insurance coverage, during which the Company will be solely responsible for defense costs and indemnity payments, the duration of which would be subject to the scope of damage awards and settlements paid. Based on the settlements made to date and the number of claims dismissed or withdrawn for lack of product identification, the Company believes that the relief sought (when specified) does not bear a reasonable relationship to its potential liability. Based upon the Company's experience to date, including the trend in annual defense and settlement costs incurred to date, and other available information (including the availability of excess insurance), the Company does not believe these cases will have a material adverse effect on its financial position and results of operations or cash flows. Claims and Litigation The Company is subject to other claims and litigation in the ordinary course of business, but does not believe that any such claim or litigation will have a material adverse effect on its financial position and results of operations or cash flows.

Equity Awards	Equity Awards The Company maintains the following long-term equity incentive plans: the TriMas Corporation Director Retainer Share Election Program, the 2011 TriMas Corporation Omnibus Incentive Compensation Plan, the TriMas Corporation 2006 Long Term Equity Incentive Plan and the TriMas Corporation 2002 Long Term Equity Incentive Plan (collectively, the "Plans"). The 2002 Long Term Equity Incentive Plan expired in 2012, such that, while existing grants will remain outstanding until exercised, vested or cancelled, no new shares may be issued under the plan. See below for details of awards under the Plans by type. Spin-off of the Cequent businesses On June 30, 2015, due to the spin-off of the Cequent businesses, stock options and restricted shares previously granted to Cequent participants were cancelled and transferred to Horizon. On July 1, 2015, the Company adjusted the number of shares outstanding, and the exercise price of stock options, as required by the anti-dilution provisions of the Plans, to maintain the intrinsic value of the outstanding equity awards immediately post spin-off. Stock Options The Company did not grant any stock option awards during the nine months ended September 30, 2015 . Information related to stock options at September 30, 2015 is as follows: Number of Weighted Average Option Price Average Remaining Contractual Life (Years) Aggregate Intrinsic Value Outstanding at January 1, 2015 (a) 298,095 $ 5.40 Exercised (40,158 ) 10.83 Cancelled (5,769 ) 5.95 Expired (2,961 ) 19.42 Outstanding at September 30, 2015 249,207 $ 4.35 2.9 $ 3,131,237 __________________________ (a) Beginning balance and weighted average option price have been retrospectively adjusted to give effect to the distribution ratio as required per the anti-dilution provisions of the Plans, resulting in 46,428 additional shares. As of September 30, 2015 , 249,207 stock options were exercisable under the Plans. The Company did not incur any stock-based compensation expense related to stock options during the nine months ended September 30, 2015 and 2014 . Restricted Shares The Company awarded the following restricted shares during the first nine months of 2015 : • granted 1,760 restricted shares of common stock to certain employees that are subject only to a service condition and vest on the first anniversary date of the award so long as the employee remains with the Company; • granted 209,825 restricted shares of common stock to certain employees which are subject only to a service condition and vest ratably over three years so long as the employee remains with the Company; • granted 42,937 restr icted shares of co mmon stock to certain employees which are subject only to a service condition and vest on the first anniversary date of the award. The awards were made to participants in the Company's short-term incentive compensation plan ("STI"), where all STI participants whose target annual award exceeds $20 thousand receive 80% of the value in earned cash and 20% in the form of a restricted stock award upon finalization of the award amount in the first quarter e ach year following the previous plan year; and • granted 32,040 restricted shares of common stock to its non-employee independent directors, which vest one year from date of grant so long as the director and/or Company does not terminate their service prior to the vesting date. In addition, the Company issued 6,275 shares related to director fee deferrals. The Company allows for its non-employee independent directors to make an annual election to defer all or a portion of their directors fees and to receive the deferred amount in cash or equity. Certain of the Company's directors have elected to defer all or a portion of their directors fees and to receive the amount in Company common stock at a future date. During the third quarter of 2015 , the Company awarded 192,348 performance-based shares of common stock to certain Company key employees which vest on March 1, 2018, so long as the employee remains with the Company. The performance criteria for these awards is based on the Company's total shareholder return ("TSR") relative to the TSR of the common stock of a pre-defined industry peer-group, measured over a period beginning September 10, 2015 and ending December 31, 2017. TSR is calculated as the Company's average closing stock price for the 20-trading days at the end of the performance period plus Company dividends, divided by the Company's average closing stock price for the 20-trading days prior to the start of the performance period. Depending on the performance achieved, the amount of shares earned can vary from 0% of the target award to a maximum of 200% of the target award. The Company estimated the grant-date fair value and term of the awards subject to a market condition using a Monte Carlo simulation model, using the following weighted-average assumptions: risk-free interest rate of 0.85% and annualized volatility of 35.8% . During 2014, the Company awarded performance-based shares of common stock to certain Company key employees which were earned based upon the achievement of the Company's pre-spin earnings per share ("EPS") cumulative average growth rate ("EPS CAGR") and average return on invested capital performance metrics over a period of three calendar years, beginning January 1, 2014 and ending on December 31, 2016. In the third quarter of 2015 , this award was modified due to the Company's spin-off of the Cequent businesses. At the time of the spin-off, the performance period was 50% complete, thus the Company decided to measure attainment for the half completed, and cancel the remaining performance shares. The Company determined that the original performance metrics resulted in a 30% attainment of the target on a weighted average basis, resulting in a reduction of 35,096 shares during the third quarter of 2015 . The Company awarded new performance-based grants of 86,924 restricted shares to these key employees, with the performance criteria based upon the Company's total TSR relative to the TSR of the common stock of a pre-defined industry peer-group and measured over the period beginning September 10, 2015 and ending December 31, 2016. Depending on the performance achieved, the amount of shares earned can vary from 0% of the target award to a maximum of 200% of the target award. These awards vest on March 5, 2017, so long as the employee remains with the Company. The Company estimated the grant-date fair value and term of the awards subject to a market condition using a Monte Carlo simulation model, using the following weighted-average assumptions: risk-free interest rate of 0.50% and annualized volatility of 38.8% . During 2013, the Company also awarded performance-based shares of common stock to certain Company key employees which were earned based upon the achievement of EPS CAGR and cash generation performance metrics over a period of three calendar years, beginning January 1, 2013 and ending on December 31, 2015. In the third quarter of 2015, this award was modified due to the spin-off of the Cequent businesses. Due to the timing of the spin-off, the Company considered the performance measurement period complete for certain employees, resulting in an attainment of 50% of the target on a weighted average basis, resulting in a reduction of 14,331 shares during the third quarter of 2015 . During 2012 , the Company awarded performance-based shares of common stock to certain Company key employees which were earned based upon the achievement of EPS CAGR and cash generation performance metrics over a period of three calendar years, beginning January 1, 2012 and ending on December 31, 2014.
