See Note 14, "Segment Information," for further information on each of the Company's reportable segments. 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.

Restructuring and Related Activities [Abstract]
Restructuring and Related Activities Disclosure [Text Block]	Facility Closure and Sale of Business Facility Closure In November 2012, the Company announced plans to close its manufacturing facility in Goshen, Indiana, moving production currently in Goshen to lower-cost manufacturing facilities during 2013, and recorded a charge, primarily for severance benefits, of approximately $1.2 million related to the termination of approximately 70 salaried employees that were involuntarily terminated. In the first quarter of 2013, upon completion of negotiations pursuant to a collective bargaining agreement, the Company recorded a charge, primarily for severance benefits of approximately $3.8 million, which is included in cost of sales in the accompanying consolidated statement of income, for its approximately 350 union hourly workers to be involuntarily terminated. As of September 30, 2013, the Company had paid approximately $1.0 million of the total hourly and salaried severance benefits, with the remainder to be paid by mid 2014. In addition, the Company expects to record approximately $1.6 million of accelerated depreciation expense between the facility closure announcement date and the closure date as a result of shortening the expected useful lives on certain machinery, equipment and leasehold improvement assets that the Company no longer will utilize following the facility closure. The Company recorded approximately $0.5 million and $1.2 million of such accelerated depreciation expense for the three and nine months ended September 30, 2013, respectively. The Company's manufacturing facility in Goshen is subject to a lease agreement expiring in 2022. Upon the cease-use date of the facility, the Company expects to record a pre-tax charge within its Cequent Americas reportable segment in the range of $4.0 million to $5.0 million for its estimate of future lease obligations. Sale of Business On August 5, 2013, the Company announced the sale of its business in Italy within the Packaging reportable segment for cash of approximately $10.3 million, with the final sale price remaining subject to a working capital adjustment, if any, which is expected to be completed by the end of the first quarter of 2014. As a result, the Company recorded a pre-tax gain of approximately $10.5 million, of which $7.9 million related to the release of historical currency translation adjustments into income, as proscribed under ASU 2013-5. See Note 2, "New Accounting Pronouncements," for further details.

Business Combinations [Abstract]

Acquisitions

During the first nine months of 2013, the Company completed acquisitions for an aggregate amount of approximately $56 million, net of cash acquired. Of these acquisitions, the most significant included Martinic Engineering, Inc. ("Martinic") within the Company's Aerospace & Defense reportable segment, Wulfrun Specialised Fasteners Limited ("Wulfrun") within the Company's Energy reportable segment and C.P. Witter Limited ("Witter") and the towing technology and business assets of AL-KO GmbH("AL-KO"), both within the Company's Cequent APEA reportable segment. Martinic is a manufacturer of highly-engineered, precision machined, complex parts for commercial and military aerospace applications, including auxiliary power units, as well as electrical, hydraulic and pneumatic systems located in the United States and generated approximately $13 million in revenue for the twelve months ended December 31, 2012. Wulfrun is a manufacturer and distributor of specialty bolting and CNC machined components for use in critical oil and gas, pipeline and power generation applications located in the United Kingdom and generated approximately $10 million in revenue for the twelve months ended December 31, 2012. Also located in the United Kingdom, Witter is a manufacturer of highly-engineered towbars and accessories which are distributed through a wide network of commercial dealers, and generated approximately $20 million in revenue for the twelve months ended March 31, 2013. The Company also completed the acquisition of the towing technology and business assets of AL-KO, located in both Germany and Finland. The acquired assets generated approximately $16 million of revenue for the twelve months ended June 30, 2013. The fair value of the AL-KO net assets acquired exceeded the purchase price, resulting in a bargain purchase gain of approximately $2.9 million, which is included in other income (expense), net in the accompanying consolidated statement of income for the three and nine months ended September 30, 2013. While the Company has recorded preliminary purchase accounting adjustments for these acquisitions, the Company may refine such amounts as it finalizes these estimates during the requisite one-year measurement periods.

The results of operations of the aforementioned acquisitions are not significant compared to the overall results of operations of the Company.

Arminak & Associates

During the first quarter of 2012, the Company acquired 70% of the membership interests of Arminak & Associates, LLC ("Arminak") for the purchase price of approximately $67.7 million. Arminak is included in the Company's Packaging reportable segment.

The purchase agreement provides the Company an option to purchase, and Arminak's previous owners an option to sell, the remaining 30% noncontrolling interest at specified dates in the future based on a multiple of future earnings, as defined in the purchase agreement. The put and call options become exercisable during the first quarters of 2014, 2015 and 2016.

The combination of a noncontrolling interest and a redemption feature resulted in a redeemable noncontrolling interest, which is classified outside of permanent equity on the accompanying consolidated balance sheet. In order to estimate the fair value of the redeemable noncontrolling interest in Arminak, the Company utilized the Monte Carlo valuation method, using variations of estimated future discounted cash flows given certain significant assumptions including expected revenue growth, minimum and maximum estimated levels of gross profit margin, future expected cash flows, amounts transferred during each put and call exercise period and appropriate discount rates. As these assumptions are not observable in the market, the calculation represents a Level 3 fair value measurement in the fair value hierarchy, as defined. The Company recorded the redeemable noncontrolling interest at fair value at the date of acquisition.

At September 30, 2013, the estimated fair value of the redeemable noncontrolling interest exceeded the redemption value. Changes in the carrying amount of redeemable noncontrolling interest are summarized as follows:



	Nine months ended September 30, 2013
	(dollars in thousands)
Beginning balance, December 31, 2012	$	26,780
Distributions to noncontrolling interests	(1,910		)
Net income attributable to noncontrolling interests	$	3,090
Ending balance, September 30, 2013	$	27,960

The Company previously presented pro forma net sales and net income attributable to TriMas Corporation as if the business combination occurred as of January 1, 2011. Certain nonrecurring adjustments for acquisition costs incurred and purchase accounting adjustments related to step-up in value and subsequent amortization of inventory were included in the first quarter 2011 pro forma results thereof. Pro forma net sales and net income attributable to TriMas Corporation for the three and nine months ended September 30, 2012 were $335.9 million and $18.7 million, respectively, and $979.9 million and $49.8 million, respectively. The supplemental pro forma information is presented for informational purposes only and is not necessarily indicative of the results of operations that might have been achieved.

Total acquisition costs incurred by the Company in connection with its purchase of Arminak, primarily related to third-party legal, accounting and tax diligence fees, were approximately $1.3 million, of which approximately $1.0 million was incurred during the first quarter of 2012. These costs are recorded in selling, general and administrative expenses in the accompanying consolidated statement of income.

Credit Agreement

The Company is a party to a credit agreement consisting of a $250.0 million senior secured revolving credit facility, which matures in October 2017 and is subject to interest at London Interbank Offered Rates ("LIBOR") plus 2.00%, a $200.0 million senior secured term loan A facility, which matures in October 2017 and is subject to interest at LIBOR plus 2.00% and a $200.0 million senior secured term loan B facility, which matures in October 2019 and is subject to interest at LIBOR plus 2.75% (subject to a 1.00% LIBOR floor) (collectively, the "Credit Agreement").

During the second quarter of 2013, the Company amended the portion of its Credit Agreement related to the $250.0 million senior secured revolving credit facility to permit revolving borrowing denominated in specified foreign currencies ("Foreign Currency Loans"), subject to a $75.0 million sub limit. Under this amendment, Foreign Currency Loans are available at rates equivalent to those previously established under the Credit Agreement, for the applicable interest period.

The Credit Agreement provides incremental term loan and/or revolving credit facility commitments in an amount not to exceed the greater of $300 million and an amount such that, after giving effect to the making of such 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, as defined. 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.

Under the Credit Agreement, if, on or prior to October 11, 2013, the Company prepays all or any portion of the term loan B facility using a new term loan facility with lower interest rate margins, then the Company will be required to pay a premium equal to 1% of the aggregate principal amount prepaid. In addition, beginning with the fiscal year ended December 31, 2013 (payable in 2014), the Company may be required to prepay a portion of its term loan A and term loan B facilities in an amount equal to a percentage of the Company's excess cash flow, as defined, which such percentage will be based on the Company's leverage ratio, as defined. For 2012, the Company prepaid $5.0 million of its former term loan B facility under the excess cash flow provision of the previous credit agreement.

The Company is also able to issue letters of credit, not to exceed $75.0 million in aggregate, against its revolving credit facility commitments. At September 30, 2013 and December 31, 2012, the Company had letters of credit of approximately $23.7 million and $23.3 million, respectively, issued and outstanding.

At September 30, 2013, the Company had $20.7 million outstanding under its revolving credit facility and had $205.6 million potentially available after giving effect to approximately $23.7 million of letters of credit issued and outstanding. At December 31, 2012, the Company had no amounts outstanding under its revolving credit facility and had $226.7 million, potentially available after giving effect to approximately $23.3 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 $206.6 million and $230.5 million at September 30, 2013 and December 31, 2012, respectively, of borrowing capacity available to it for general corporate purposes.

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 $250.0 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 terms of the Credit Agreement contain certain limitations on the distribution of funds from TriMas Company LLC, the Company's principal subsidiary. The terms of the Credit Agreement require the Company and its subsidiaries to meet certain restrictive financial covenants and ratios computed quarterly, including a leverage ratio (total consolidated indebtedness plus outstanding amounts under the accounts receivable securitization facility over consolidated EBITDA, as defined) and an interest expense coverage ratio (consolidated EBITDA, as defined, over cash interest expense, as defined). The Company was in compliance with its covenants at September 30, 2013.

As of September 30, 2013 and December 31, 2012, the Company's term loan A facility traded at approximately 98.5% and 99.3% of par value, respectively, and the Company's term loan B facility traded at approximately 100.0% and 99.9% of par value, respectively. The valuations of the term loans 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. Under this facility, TSPC, from time to time, may sell an undivided fractional ownership interest in the pool of receivables up to approximately $105.0 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 1.20% and 1.50% as of September 30, 2013 and 2012, respectively, and a fee on the unused portion of the facility of 0.40% and 0.45% as of September 30, 2013 and 2012, respectively.

The Company had $55.0 million and $18.0 million outstanding under the facility as of September 30, 2013 and December 31, 2012, respectively, and $36.0 million and $51.9 million, respectively, available but not utilized. Aggregate costs incurred under the facility were $0.4 million and $0.3 million for the three months ended September 30, 2013 and 2012, respectively, and $1.1 million and $0.8 million for the nine months ended September 30, 2013 and 2012, respectively, and are included in interest expense in the accompanying consolidated statement of income. The facility expires on October 12, 2017.

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 securitization agreement. As of September 30, 2013, the cost of funds under the facility was based on an average liquidation period of the portfolio of approximately 1.6 months and an average discount rate of 1.8%.

Other Bank Debt

The Company's Australian subsidiary is party to a debt agreement which matures on December 31, 2013 and is secured by substantially all the assets of the subsidiary. At September 30, 2013 and December 31, 2012, the balance outstanding under this agreement was approximately $8.4 million and $4.8 million, respectively, at an average interest rate of 2.6% and 3.2%, respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments

In December 2012, the Company entered into interest rate swap agreements to fix the LIBOR-based variable portion of the interest rates on its term loan facilities. The term loan A swap agreement fixes the LIBOR-based variable portion of the interest rate, beginning February 2013, on a total of $175.0 million notional amount at 0.74% and expires on October 11, 2017. The term loan B swap agreement fixes the LIBOR-based variable portion of the interest rate, beginning February 2015, on a total of $150.0 million notional amount at 2.05% and expires on October 11, 2019. The Company has designated both swap agreements as cash flow hedges.

In March 2012, the Company entered into an interest rate swap agreement to fix the LIBOR-based variable portion of the interest rate on a total of $100.0 million notional amount of its previous term loan B facility. The swap agreement fixed the LIBOR-based variable portion of the interest rate at 1.80% through June 2016. At inception, the Company formally designated this swap agreement as a cash flow hedge. However, upon the Company's amendment and restatement of its credit agreement during the fourth quarter of 2012, the Company determined that the interest rate swap was no longer expected to be an effective economic hedge and terminated the interest rate swap and repaid the obligation.

As of September 30, 2013 and December 31, 2012, the fair value carrying amount of the Company's interest rate swaps are recorded as follows:

Commitments and Contingencies

Asbestos

As of September 30, 2013, the Company was a party to 1,078 pending cases involving an aggregate of 7,950 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, 2012	8,048	367	519	16	$	14,513	$	2,650,000
Nine Months Ended September 30, 2013	7,880	283	179	34	$	2,001	$	1,981,000

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 7,950 claims pending at September 30, 2013, 133 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

$0.6 to $5.0

$5.0+

$0.0 to $2.5

$2.5 to $5.0

$5.0+

Number of claims

106

115

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 $6.4 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.

Ordinary Course Claims

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.

The Company maintains the following long-term equity incentive plans: 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.

Stock Options

The Company did not grant any stock options during the nine months ended September 30, 2013. Information related to stock options at September 30, 2013 is as follows:



	Number of Options		Weighted Average Option Price		Average Remaining Contractual Life (Years)	Aggregate Intrinsic Value

Outstanding at September 30, 2013	354,725		$	10.33	4.2	$	9,569,015

As of September 30, 2013, 351,703 stock options were exercisable under the Plans. In addition, during the nine months ended September 30, 2013, 11,698 stock options vested for which the associated fair value was less than $0.1 million. The fair value of options which vested during the nine months ended September 30, 2012 was $0.4 million.

The Company did not incur significant stock-based compensation expense related to stock options during the nine months ended September 30, 2013 and 2012.

Restricted Shares

During the nine months ended September 30, 2013, the Company issued 4,013 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.

The Company also awarded multiple restricted stock grants during the first quarter of 2013. First, the Company granted 29,498 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.

The Company awarded 41,480 restricted shares of common stock to certain employees during the first quarter of 2013. These shares 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 each year following the previous plan year.

The Company awarded 238,808 restricted shares of common stock to certain Company key employees during the first quarter of 2013. Half of the restricted shares granted are service-based restricted stock units. These awards vest ratably over three years. The other half of the shares are subject to a performance condition and are earned based upon the achievement of two performance metrics over a period of three calendar years, beginning on January 1, 2013 and ending on December 31, 2015. Of this award, 75% of the awards are earned based upon the Company's earnings per share ("EPS") cumulative average growth rate ("EPS CAGR") over the performance period. The remaining 25% of the grants are earned based upon the Company's cash generation results. Cash generation is defined as the Company's cumulative three year cash flow from operating activities less capital expenditures, as publicly reported by the Company, plus or minus special items that may occur from time-to-time, divided by the Company's three-year income from continuing operations as publicly reported by the Company, plus or minus special items that may occur from time-to-time. Depending on the performance achieved for these two metrics, the amount of shares earned can vary from 30% of the target award to a maximum amount of 200% of the target award for the cash flow metric and 250% of the target award for the EPS CAGR metric. However, if these performance metrics are not achieved, no award will be earned. The performance awards vest on a "cliff" basis at the end of the three-year performance period.

In addition, the Company granted 17,240 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 his services prior to the vesting date.

During 2012, the Company awarded restricted shares of common stock to certain Company key employees which are performance-based grants. Of this award, 60% are earned based on 2012 EPS growth, and the remaining 40% are earned based on the EPS CAGR for 2012 and 2013. For the 60% of shares subject to the 2012 earnings per share growth metric only, the performance conditions were satisfied, resulting in an attainment level of 175% of target. This resulted in an additional 72,576 share grants during the first quarter of 2013.

Information related to restricted shares at September 30, 2013 is as follows:



	Number of Unvested Restricted Shares		Weighted Average Grant Date Fair Value		Average Remaining Contractual Life (Years)	Aggregate Intrinsic Value
Outstanding at January 1, 2013	636,037		$	22.02

In October 2013, the Company entered into new senior secured credit facilities, pursuant to which the Company was able to reduce interest rates, extend maturities and increase its available liquidity compared to the existing Credit Agreement. Below is a summary of the key terms of the new facilities:



Instrument	Amount ($ in millions)		Maturity Date	Initial Interest Rate
Senior Secured Revolving Credit facility	$	575.0	10/16/2018	LIBOR plus 1.625%
Senior Secured Term Loan A facility	$	175.0	10/16/2018	LIBOR plus 1.625%

The Company used the proceeds from borrowings under the new facilities to repay all outstanding amounts under the existing Credit Agreement.

In October 2013, the Company acquired the stock of Mac Fasteners, Inc. ("Mac Fasteners") for the cash purchase price of approximately $34 million, plus the potential for up to approximately $6 million of contingent consideration, payable based on attainment of certain future operating results. The purchase price remains subject to the finalization of a net working capital adjustment, if any, which is expected to be completed by the end of the first quarter of 2014.
