	Description of Business
	Generac Holdings Inc. (the Company) owns all of the common stock of Generac Acquisition Corp. (GAC), which in turn, owns all of the common stock of Generac Power Systems, Inc. (the Subsidiary and the Borrower). The Company is a leading designer and manufacturer of a wide range of generators and other engine powered products for the residential, light commercial, industrial and construction markets.
	The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany amounts and transactions have been eliminated in consolidation.
	The condensed consolidated balance sheet as of September 30, 2013, the condensed consolidated statements of comprehensive income for the three and nine months ended September 30, 2013 and 2012, and the condensed consolidated statements of cash flows for the nine months ended September 30, 2013 and 2012 have been prepared by the Company and have not been audited. In the opinion of management, all adjustments, consisting of only normal recurring adjustments necessary for the fair presentation of the financial position, results of operation and cash flows, have been made. The results of operations for any interim period are not necessarily indicative of the results to be expected for the full year.
	Expenses are charged to operations in the year incurred. However, for interim reporting purposes certain expenses are charged to operations based on a proportionate share of annual amounts rather than as they are actually incurred.
	The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles 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 condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
	Certain information and footnote disclosure normally included in consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2012.
	Accumulated Other Comprehensive Loss
	The components of accumulated other comprehensive loss, net of tax, at September 30, 2013 and December 31, 2012 are as follows:
		September 30,			December 31,
		2013			2012
	Foreign currency translation adjustments	$	852		$	(34	)

Derivative Instruments and Hedging Activities [Abstract]	'
Derivative Instruments and Hedging Activities	'
	2. Derivative Instruments and Hedging Activities
	The Company records all derivatives in accordance with ASC 815, Derivatives and Hedging (ASC 815), which requires all derivative instruments be reported on the consolidated balance sheets at fair value and establishes criteria for designation and effectiveness of hedging relationships. The Company is exposed to market risk such as changes in commodity prices, foreign currencies, and interest rates. The Company does not hold or issue derivative financial instruments for trading purposes.
	Commodities
	The primary objectives of the commodity risk management activities are to understand and mitigate the impact of potential price fluctuations on the Company’s financial results and its economic well-being. While the Company’s risk management objectives and strategies will be driven from an economic perspective, it attempts, where possible and practical, to ensure that the hedging strategies it engages in can be treated as “hedges” from an accounting perspective or otherwise result in accounting treatment where the earnings effect of the hedging instrument provides substantial offset (in the same period) to the earnings effect of the hedged item. Generally, these risk management transactions will involve the use of commodity derivatives to protect against exposure resulting from significant price fluctuations.
	The Company primarily utilizes commodity contracts with maturities of less than 12 months. The impact of such contracts is intended to offset the effect of price fluctuations on actual inventory purchases. Outstanding commodity forward contracts in place to hedge the Company’s projected commodity purchases were as follows.
	As of September 30, 2013:
	Commodity	Trade Date	Effective Date	Notional Amount	Termination Date
	Copper	2/26/13	3/1/13	$2,677	12/31/13
	Copper	3/1/13	3/1/13	2,636	12/31/13
	Copper	4/15/13	5/1/13	4,033	12/31/13
	Copper	6/21/13	10/1/13	2,169	6/30/14
	As of December 31, 2012:
	Commodity	Trade Date	Effective Date	Notional Amount	Termination Date
	Copper	10/29/12	1/1/13	$3,472	9/30/13
	As of  September 30, 2012:
	Commodity	Trade Date	Effective Date	Notional Amount	Termination Date
	Copper	5/18/12	7/1/12	$1,898	12/31/12
	Because these contracts do not qualify for hedge accounting, gains and losses are recorded in cost of goods sold in the Company’s consolidated statements of comprehensive income. Total gains (losses) recognized for the three and nine months ended September 30, 2013 were $578 and $(540), respectively. Total gains recognized for the three and nine months ended September 30, 2012 were $68 and $322, respectively.
	Foreign Currencies
	The Company is exposed to foreign currency exchange risk as a result of transactions denominated in other currencies. The Company periodically utilizes foreign currency forward purchase and sales contracts to manage the volatility associated with foreign currency purchases in the normal course of business. Contracts typically have maturities of 12 months or less. There were no foreign currency hedge contracts outstanding as of September 30, 2013, December 31, 2012 or September 30, 2012.
	Interest Rate Swaps
	The Company has one interest rate swap agreement outstanding as of September 30, 2013. The interest rate swap agreement was entered into on April 1, 2011. The effective date of the swap was October 1, 2012 with a notional amount of $100,000, a fixed LIBOR rate of 2.22% and an expiration date of October 1, 2013.
	The Company had formally documented all relationships between interest rate hedging instruments and hedged items, as well as its risk-management objectives and strategies for undertaking various hedge transactions.  As discussed in Note 8 – Credit Agreements, on February 9, 2012, a subsidiary of the Company entered into a new credit agreement with certain commercial banks and other lenders.  From inception through February 9, 2012, the Company’s interest rate swap agreements qualified as cash flow hedges. For derivatives that are designated and qualify as a cash flow hedge, the effective portion of the gain or loss on the derivative’s change in fair value is reported as a component of accumulated other comprehensive income (loss). The cash flows of the swaps are recognized as adjustments to interest expense each period. The ineffective portion of the derivatives’ change in fair value, if any, is immediately recognized in earnings. The Company assessed on an ongoing basis whether derivatives used in hedging transactions are highly effective in offsetting changes in cash flows of hedged items.  The impact of hedge ineffectiveness on earnings was not material for the periods prior to February 9, 2012.
	As noted above and in Note 8 – Credit Agreements, on February 9, 2012, a subsidiary of the Company entered into a new credit agreement (“Credit Agreement”) with certain commercial banks and other lenders.  The future cash flows associated with the Credit Agreement were materially consistent with that of the former credit agreement, resulting in the continued designation of the interest rate swap agreements as cash flow hedges. However, as a result of a change in certain critical terms between the Credit Agreement and former credit agreement, the interest rate swap agreements in place on the date of refinancing were required to be measured for hedge effectiveness. The ineffective portion of the change in fair value of the cash flow hedges was not material for the period from February 9, 2012 to May 30, 2012.
	Also as discussed in Note 8 – Credit Agreements, on May 30, 2012, a subsidiary of the Company amended and restated its existing Credit Agreement by entering into a new credit agreement (“Term Loan Credit Agreement”) with certain commercial banks and other lenders. Due to the incorporation of a new interest rate floor provision in the Term Loan Credit Agreement, which constitutes a change in critical terms, the Company concluded that as of May 30, 2012, the outstanding swaps would no longer be highly effective in achieving offsetting changes in cash flows during the periods the hedges are designated.  As a result, the Company was required to de-designate the hedges as of May 30, 2012.  For the period between May 31, 2012 and September 30, 2013, the effective portion of the swaps prior to the change (i.e. amounts previously recorded in Accumulated Other Comprehensive Loss) were amortized into interest expense over the period of the hedged interest payments which had various dates through October 1, 2013.
	The following table presents the fair value of the Company’s derivatives not designated as hedging instruments:
			September 30,				December 31,
			2013				2012
	Commodity contracts		$	(28	)		$	111
	Interest rate swaps			-				(2,973	)
	Net derivatives liability		$	(28	)		$	(2,862	)
	The fair value of the interest rate swaps is included in other current liabilities in the condensed consolidated balance sheets as of December 31, 2012. The fair value of the commodity contracts is included in other current liabilities and other assets in the condensed consolidated balance sheets as of September 30, 2013 and December 31, 2012, respectively. The fair value of the derivative contracts considers the Company’s credit risk.  Excluding the impact of credit risk, the fair value of the derivative contracts as of September 30, 2013 and December 31, 2012 is a liability of $(28) and $(2,936), respectively, which represents the amount the Company would need to pay to exit the agreements on those dates.
	The following presents the impact of interest rate swaps and commodity contracts on the condensed consolidated statements of comprehensive income for the three and nine months ended September 30, 2013 and 2012:
		Amount of gain recognized in Accumulated Other Comprehensive Loss for the three months ended			Location of gain (loss) recognized in net income on ineffective portion of hedges

Fair Value Measurements	'
	3. Fair Value Measurements
	ASC 820-10, Fair Value Measurements and Disclosures, among other things, defines fair value, establishes a consistent framework for measuring fair value, and expands disclosure for each major asset and liability category measured at fair value on either a recurring basis or nonrecurring basis. ASC 820-10 clarifies that fair value is an exit price, representing the amount that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the pronouncement establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: (Level 1) observable inputs such as quoted prices in active markets; (Level 2) inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and (Level 3) unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.
	Assets and liabilities measured at fair value are based on the market approach, which uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities.
	The Company believes the carrying amount of its financial instruments (cash and cash equivalents, restricted cash, accounts receivable, accounts payable, accrued liabilities and short-term borrowings), excluding long-term borrowings, approximates the fair value of these instruments based upon their short-term nature. The fair value of long-term borrowings, including amounts classified as current, which have an aggregate carrying value of $1,200,000, was approximately $1,191,000 (Level 2) at September 30, 2013, as calculated based on independent valuations whose inputs and significant value drivers are observable.
	Assets (liabilities) measured at fair value on a recurring basis are as follows:
					Fair Value Measurement Using
					Quoted Prices in Active Markets for Identical Contracts (Level 1)		Significant
		Total					Other Observable Inputs
		30-Sep-13					(Level 2)
	Commodity contracts	$	(28	)	$	–	$	(28	)
					Fair Value Measurement Using
					Quoted Prices in Active Markets for Identical Contracts (Level 1)		Significant
		Total					Other Observable Inputs
		31-Dec-12					(Level 2)
	Interest rate swaps	$	(2,973	)	$	–	$	(2,973	)
	Commodity contracts	$	111		$	–	$	111
	The valuation techniques used to measure the fair value of derivative contracts classified as level 2, all of which have counterparties with high credit ratings, were valued based on quoted market prices or model driven valuations using significant inputs derived from or corroborated by observable market data. The fair value of derivative contracts above considers the Company’s credit risk in accordance with ASC 820-10.

	Acquisition of Ottomotores
	On December 8, 2012, a subsidiary of the Company acquired all of the shares of Ottomotores UK Limited and its affiliates, including the operations of Ottomotores Mexico and Ottomotores Brazil (collectively, “Ottomotores”).  Ottomotores was founded in 1950 and is located in Mexico City, Mexico and Curitiba, Brazil.  Ottomotores is a leading manufacturer in the Mexican market for industrial diesel gensets ranging in size from 15kW to 2,500kW and is a significant market participant throughout all of Latin America.
	The cash paid at closing of $44,769, net of cash acquired, included an estimate of acquired working capital. This estimate was finalized during the second quarter of 2013 to reflect actual working capital acquired as well as cash acquired and debt assumed, resulting in a $6,278 decrease to the purchase price.
	The Company recorded a preliminary purchase price allocation during the fourth quarter of 2012 based upon a fair value appraisal by a third party valuation firm. As a result, the Company recorded approximately $16,100 of intangible assets, including approximately $5,050 of goodwill, as of the acquisition date.  The purchase price allocation was finalized during the second quarter of 2013, resulting in an additional $2,590 of intangible assets and a $439 decrease to goodwill.

	On August 1, 2013, a subsidiary of the Company acquired all of the shares of Tower Light SRL and its wholly-owned subsidiaries (collectively, “Tower Light”) for a purchase price, net of cash acquired and inclusive of estimated earn-out payments, of $76,484.  Headquartered outside Milan, Italy, Tower Light is a leading developer and supplier of mobile light towers throughout Europe, the Middle East and Africa.  Tower Light has built a leading market position in the equipment rental markets by leveraging its broad product offering and strong global distribution network in over 50 countries worldwide.
	The net cash paid at closing of $80,239 included a cash deposit of $6,645 into an escrow account to fund future earn-out payments required by the purchase agreement, which is recorded as restricted cash on the condensed consolidated balance sheet. The difference between the total escrow deposit and the Company’s estimated future earn-out payments is reflected as a reduction in the purchase price.  Additionally, the cash paid at closing included an estimate of acquired working capital. This estimate was finalized during third quarter of 2013, resulting in an additional $300 decrease to the purchase price. This acquisition was funded solely by existing cash.
	The Company recorded a preliminary purchase price allocation during the third quarter of 2013 based upon a fair value appraisal by a third party valuation firm.  As a result, the Company recorded approximately $67,900 of intangible assets, including approximately $38,400 of goodwill, as of the acquisition date.  The accompanying condensed consolidated financial statements include the results of Tower Light from August 1, 2013 through September 30, 2013.

	On February 9, 2012, a subsidiary of the Company (“Borrower”) entered into a credit agreement (“Credit Agreement”) with certain commercial banks and other lenders.  The Credit Agreement provided for borrowings under a $150,000 revolving credit facility, a $325,000 tranche A term loan facility and a $250,000 tranche B term loan facility. The revolving credit facility and tranche A term loan facility were scheduled to mature in February 2017 and the tranche B term loan facility was scheduled to mature in February 2019.  Proceeds received by the Company from loans made under the 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 agreement was comprised of a revolving credit facility and a first-lien term loan which were scheduled to mature in November 2012 and November 2013, respectively.
	On May 30, 2012, the Borrower amended and restated its then existing Credit Agreement by entering into a new credit agreement (“Term Loan Credit Agreement”) and a new revolving credit agreement (“ABL Credit Agreement”) with certain commercial banks and other lenders.  The Term Loan Credit Agreement provided for a $900,000 term loan B credit facility and a $125,000 uncommitted incremental term loan facility (“Term Loan”).  The ABL Credit Agreement provided for borrowings under a $150,000 senior secured ABL revolving credit facility. The size of the ABL revolving credit facility could have increased by $50,000 pursuant to an uncommitted incremental credit facility. The Term Loan Credit Agreement was scheduled to mature in May 2018 and the ABL Credit Agreement was scheduled to mature in May 2017.  Proceeds received by the Company from loans made under the Term Loan Credit Agreement, together with cash on hand, were used to repay amounts outstanding under the Company’s previous Credit Agreement and pay a special cash dividend of $6.00 per share on the Company’s common stock.
	The Term Loan Credit Agreement amortized in equal installments of 0.25% of the original principal amount on the first day of April, July, October and January commencing on October 1, 2012 until the maturity date of the Term Loan.  The interest rate on the Term Loan was based upon either a base rate plus an applicable margin of 4.00% or adjusted LIBOR rate plus an applicable margin of 5.00%, subject to a LIBOR floor of 1.25%.
	On May 31, 2013, the Borrower amended and restated its then existing “Term Loan Credit Agreement” by entering into a new term loan credit agreement (“New Term Loan Credit Agreement”) with certain commercial banks and other lenders.  The New Term Loan Credit Agreement provides for a $1,200,000 term loan B credit facility (the “New Term Loan”) and includes a $300,000 uncommitted incremental term loan facility. The New Term Loan Credit Agreement matures on May 31, 2020.  Proceeds from the New Term Loan were used to repay amounts outstanding under the Company’s previous Term Loan Credit Agreement and to fund a special cash dividend of $5.00 per share on the Company’s common stock (refer to Note 14 – Special Cash Dividend for additional details). Remaining funds from the New Term Loans were used for general corporate purposes and to pay related financing fees and expenses.
	The New Term Loan is guaranteed by all of the Borrower’s wholly-owned domestic restricted subsidiaries, GAC and the Company, and is secured by associated collateral agreements which pledge a first priority lien on virtually all of the Borrower’s assets, including fixed assets and intangibles, and the assets of the guarantors (other than the Company), other than all cash, trade accounts receivable, inventory, and other current assets and proceeds thereof, which will be secured by a second priority lien.
	The New Term Loan amortizes in equal installments of 0.25% of the original principal amount of the New Term Loan payable on the first day of April, July, October and January commencing on October 1, 2013 until the final maturity date of the New Term Loan on May 31, 2020.  The New Term Loan initially bears interest at rates based upon either a base rate plus an applicable margin of 1.75% or adjusted LIBOR rate plus an applicable margin of 2.75%, subject to a LIBOR floor of 0.75%. Beginning in the second quarter of 2014, the applicable margin related to base rate loans can be reduced to 1.50% and the applicable margin related to LIBOR rate loans can be reduced to 2.50%, in each case, if the Borrower’s net debt leverage ratio falls below 3.00 to 1.00.
	The New Term Loan Credit Agreement contains restrictions on the Borrower’s ability to pay distributions and dividends (but which permitted the payment of the special cash dividend described in Note 14 – Special Cash Dividend below.). Payments can be made by the Borrower to the Company or other parent companies for certain expenses such as operating expenses in the ordinary course, fees and expenses related to any debt or equity offering and to pay franchise or similar taxes. Dividends can be used to repurchase equity interests, subject to limitations in certain circumstances. Additionally, the New Term Loan Credit Agreement restricts the aggregate amount of dividends and distributions that can be paid and, in certain circumstances, requires pro forma compliance with certain fixed charge coverage ratios or gross leverage ratios, as applicable in order to pay certain dividends and distributions. The New Term Loan Credit Agreement also contains other affirmative and negative covenants that, among other things, limit the incurrence of additional indebtedness, liens on property, sale and leaseback transactions, investments, loans and advances, mergers or consolidations, asset sales, acquisitions, transactions with affiliates, prepayments of certain other indebtedness and modifications of our organizational documents. The New Term Loan Credit Agreement does not contain any financial maintenance covenants.
	The New Term Loan 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 (defined in the New Term Loan Credit Agreement). A bankruptcy or insolvency event of default will cause the obligations under the New Term Loan Credit Agreement to automatically become immediately due and payable.
	Concurrent with the closing of the New Term Loan Credit Agreement, on May 31, 2013, the Borrower amended its existing ABL Credit Agreement (the “New ABL Credit Agreement”). The amendment provides for a one year extension of the maturity date in respect of the $150,000 senior secured ABL revolving credit facility provided under the ABL Credit Agreement (the “ABL Facility”). The extended maturity date of the ABL Facility is May 31, 2018.
	Borrowings under the ABL Facility are guaranteed by all of the Borrower’s wholly-owned domestic restricted subsidiaries and GAC, and are secured by associated collateral agreements which pledge a first priority lien on all cash, trade accounts receivable, inventory, and other current assets and proceeds thereof, and a second priority lien on all other assets, including fixed assets and intangibles of the Borrower, certain domestic subsidiaries of the Borrower and the guarantors (other than the Company).
	Borrowings under the ABL Facility continue to bear interest at rates based upon either a base rate plus an applicable margin of 1.00% or adjusted LIBOR rate plus an applicable margin of 2.00%, in each case, subject to adjustments based upon average availability under the ABL Facility. The New ABL Credit Agreement requires the Borrower to maintain a minimum consolidated fixed charge coverage ratio of 1.0x, tested on a quarterly basis, when Availability plus the amount of Qualified Cash (up to $5,000) (as defined in the New ABL Credit Agreement) under the ABL Facility is less than the greater of (i) 10.0% of the Line Cap (as defined in the New ABL Credit Agreement) and (ii) $10,000. The New ABL Credit Agreement also contains covenants and events of default substantially similar to those in the New Term Loan Credit Agreement, as described above.  As of September 30, 2013, no amounts were outstanding under the ABL Facility.  As of September 30, 2013, the Company had $116,521 of unrestricted cash and cash equivalents and $147,138 of availability under the ABL Facility, net of outstanding letters of credit.
	On February 11, 2013, the Company made an $80,000 voluntary prepayment of debt with available cash on hand that was applied to future principal amortizations on the Term Loan Credit Agreement.  As a result, the Company wrote off $1,839 of original issue discount and capitalized debt issuance costs during the first quarter of 2013.  On May 2, 2013, the Company made an additional $30,000 voluntary prepayment of existing debt with available cash on hand.  As a result, the Company wrote off $924 of original issue discount and capitalized debt issuance costs during the second quarter of 2013.
	In connection with the May 31, 2013 refinancing and in accordance with ASC 470-50, Debt Modifications and Extinguishments, the Company capitalized $21,824 of new debt issuance costs, recorded $13,797 of fees paid to creditors as a debt discount, and expensed $7,100 of transaction fees. The Company evaluated on a lender by lender basis if the debt related to returning lenders was significantly modified or not, resulting in the write-off of $5,473 in unamortized debt issuance costs and original issue discount relating to the previous Term Loan Credit Agreement and ABL Credit Agreement. Amounts expensed are recorded as a loss on extinguishment of debt in the condensed consolidated statement of comprehensive income for the nine months ended September 30, 2013. The Company amortizes both the capitalized debt issuance costs and the original issue discount on its loans under the effective interest method.
	As of September 30, 2013 and December 31, 2012, short-term borrowings consisted primarily of borrowings by our foreign subsidiaries on local lines of credit, which totaled $18,013 and $12,550, respectively.

	9. Earnings Per Share
	Basic earnings per share is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Except where the result would be anti-dilutive, dilutive earnings per share is calculated by assuming the vesting of unvested restricted stock and the exercise of stock options, as well as their related income tax benefits.  The following table reconciles the numerator and the denominator used to calculate basic and diluted earnings per share:

	During the nine months ended September 30, 2013, approximately 442,000 restricted stock awards vested. As permitted by the Company’s equity incentive plan, these restricted stock awards were net-share settled such that the Company withheld shares with a value equivalent to the employees’ minimum statutory obligation for the applicable income and other employment taxes.  In effect, the Company repurchased, and classified as treasury stock, 163,099 of the issued shares at fair value (total cost of $6,552), and used the cash on behalf of the employees to satisfy the tax withholding requirements.  This tax amount, together with an additional $5,916 of taxes paid related to the net share settlement of stock option exercises during the nine months ended September 30, 2013, is reflected as a cash outflow in the financing section of the condensed consolidated statement of cash flows.
	Excess tax benefits of $9,491 were recorded during the first three quarters of 2013 as a result of the stock activity discussed above. This amount is reflected as a cash inflow in the financing section of the condensed consolidated statement of cash flows.

The Company receives payment from the finance company after shipment of product to the dealer. The Company participates in the cost of dealer financing up to certain limits and has agreed to repurchase products repossessed by the finance company, but does not indemnify the finance company for any credit losses they incur. The amount financed by dealers which remained outstanding under this arrangement at September 30, 2013 and December 31, 2012 was approximately $25,132 and $16,600 respectively.
	In the normal course of business, the Company is named as a defendant in various lawsuits in which claims are asserted against the Company.

	On June 21, 2013, the Company used a portion of the proceeds from the May 31, 2013 debt refinancing (see Note 8 – Credit Agreements) to pay a special cash dividend of $5.00 per share on its common stock, resulting in payments totaling $340,772 to shareholders. The Company also recorded a liability of $1,322, included in other accrued liabilities in the condensed consolidated balance sheet, for dividends declared on unvested restricted stock awards. Payment of these dividends will be made when the underlying restricted stock awards vest.
	In connection with the special dividend, and pursuant to the terms of the Company’s stock option plan, certain adjustments are required to be made to stock options outstanding under the plan in order to avoid dilution of the intended benefits which would otherwise result as a consequence of the special dividend. As such, the strike price for all outstanding stock option awards outstanding prior to the special dividend date was adjusted by the $5.00 special dividend amount. There was no change to compensation expense as a result of this adjustment.
	The balance of retained earnings as of the dividend declaration date was $4,934. The dividends paid were first charged to retained earnings and dividends in excess of retained earnings were recorded as a reduction to additional paid-in capital.

	Acquisition of Baldor
	On October 7, 2013, a subsidiary of the Company announced the signing of a purchase agreement with Baldor Electric Company (“Baldor”), a wholly-owned subsidiary of ABB Group, to acquire substantially all of the assets of Baldor’s generator products division (“Baldor Generators”). Located in Oshkosh, Wisconsin, Baldor Generators offers a complete line of portable, mobile, standby and prime power generators ranging from 3kW to 2.5MW throughout North America.  The transaction closed on November 1, 2013.
	Since the acquisition did not close prior to September 30, 2013, the accompanying condensed consolidated financial statements do not reflect any adjustments related to the acquisition, although certain transactions costs relating to the acquisition are included in other expense in the condensed consolidated statement of operations for the three and nine months ended September 30, 2013.

Earnings Per Share [Abstract]	'
Computation of basic and diluted net income per share	'
	Basic earnings per share is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Except where the result would be anti-dilutive, dilutive earnings per share is calculated by assuming the vesting of unvested restricted stock and the exercise of stock options, as well as their related income tax benefits.  The following table reconciles the numerator and the denominator used to calculate basic and diluted earnings per share:
		Three months ended September 30,				Six months ended September 30,
		2013		2012		2013		2012

	(1) Excludes approximately 8,000 and 18,000 stock options for the three and nine month periods ended September 30, 2013, respectively, as the impact of such awards was anti-dilutive. Excludes approximately 2,000 and 259,000 stock options for the three and nine month periods ended September 30, 2012, respectively, as the impact of such awards was anti-dilutive.

Covenant description

'

'

'

'

'

'

'The New ABL Credit Agreement requires the Borrower to maintain a minimum consolidated fixed charge coverage ratio of 1.0x, tested on a quarterly basis, when Availability plus the amount of Qualified Cash (up to $5,000) (as defined in the New ABL Credit Agreement) under the ABL Facility is less than the greater of (i) 10.0% of the Line Cap (as defined in the New ABL Credit Agreement) and (ii) $10,000. The New ABL Credit Agreement also contains covenants and events of default substantially similar to those in the New Term Loan Credit Agreement, as described above. As of September 30, 2013, no amounts were outstanding under the ABL Facility.
