Subsequent Events [Abstract]
Subsequent Events	16. Subsequent Events The Company evaluated its financial statements for subsequent events through the date the financial statements were available to be issued. The Company is not aware of any subsequent events which require recognition or disclosure in the financial statements, except as disclosed below. Acquisition of Gen-Tran Corporation - On February 1, 2012, a subsidiary of the Company acquired substantially all of the assets and assumed certain liabilities of Gen-Tran Corporation, a leading transfer switch and portable generator accessory manufacturer located in Alpharetta, GA. The acquisition is not material to the Company's consolidated financial statements. Refinancing of Revolving Credit Facility and Credit Agreement - On February 9, 2012, a subsidiary of the Company (the “Borrower”) entered into a new credit agreement with certain commercial banks and other lenders. The new credit agreement provides for borrowings under a new $150.0 million revolving credit facility, a $325.0 million tranche A term loan facility and a $250.0 million tranche B term loan facility. The new revolving credit facility and tranche A term loan facility mature February 9, 2017, and the tranche B term loan facility matures February 9, 2019. Proceeds received by the Company from loans made under the new credit agreement were used to repay in full all outstanding borrowings under the former credit agreement, dated as of November 10, 2006, as amended from time to time, and for general corporate purposes. The Company's former credit facility is comprised of a revolving credit facility and a first-lien term loan, which were scheduled to mature in November 2012 and November 2013, respectively. The new borrowings are secured by associated collateral agreements which pledge virtually all assets of the Borrower. The new credit agreement requires the Borrower, among other things, to meet certain financial and nonfinancial covenants and maintain a consolidated net leverage ratio not exceeding certain agreed levels and an interest coverage ratio not to decline below certain agreed levels. The new revolving credit facility and tranche A term loan facility initially bear interest at rates based upon either a base rate plus an applicable margin of 1.25% or adjusted LIBOR rate plus an applicable margin of 2.25%. The tranche B term loan facility bears interest at rates based upon either a base rate (which, with respect to such tranche B term loan facility, will not be less than 2.00%) plus an applicable margin of 1.75% or adjusted LIBOR rate (which, with respect to such tranche B term loan facility, will not be less than 1.00%) plus an applicable margin of 2.75%. In subsequent periods, the new revolving credit facility and the Tranche A term loan facility will bear interest at rates based upon either a base rate plus an applicable margin ranging from 0.75% to 1.50% or adjusted LIBOR rate plus an applicable margin ranging from 1.75% to 2.50%, each determined based on a leverage ratio. The new credit agreement restricts the circumstances in which distributions and dividends can be paid by the Borrower. Payments can be made by the Borrower to the Company for certain expenses such as operating expenses in the ordinary course and dividends can be used to repurchase equity interests, subject to limitation in certain circumstances. Additionally, the new credit agreement restricts the aggregate amount of dividends and distributions that can be paid and, in certain circumstances, requires the maintenance of certain leverage ratios in order to pay certain dividends or distributions. The new credit agreement contains customary events of default, including, among others, nonpayment of principal, interest or other amounts, failure to perform covenants, inaccuracy of representations or warranties in any material respect, cross-defaults with other material indebtedness, certain undischarged judgments, the occurrence of certain ERISA or bankruptcy or insolvency events or the occurrence of a change in control (as defined in the new credit agreement). Upon an event of default under the new credit agreement, the lenders may declare the loans and all other obligations under the new credit agreement immediately due and payable and require the Borrower to cash collateralize the outstanding letter of credit obligations. A bankruptcy or insolvency event causes such obligations to automatically become immediately due and payable.
