Significant Accounting Policies

2. Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany amounts and transactions have been eliminated in consolidation.

Cash Equivalents

The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.

Concentration of Credit Risk

The Company maintains the majority of its cash in one commercial bank in multiple operating and investment accounts. Balances on deposit are insured by the Federal Deposit Insurance Corporation (FDIC) up to specified limits. Balances in excess of FDIC limits are uninsured.

One customer accounted for approximately 9% and 12% of accounts receivable at December 31, 2012 and December 31, 2011, respectively. No one customer accounted for greater than 7%, 10% and 10%, respectively, of net sales during the years ended December 31, 2012, 2011, or 2010.

Accounts Receivable

Receivables are recorded at their face value amount less an allowance for doubtful accounts. The Company estimates and records an allowance for doubtful accounts based on specific identification and historical experience. The Company writes off uncollectible accounts against the allowance for doubtful accounts after all collection efforts have been exhausted. Sales are generally made on an unsecured basis.

Inventories

Inventories are stated at the lower of cost or market, with cost determined using the first-in, first-out method.

Property and Equipment

Property and equipment are recorded at cost and are being depreciated using the straight-line method over the estimated useful lives of the assets, which are summarized below (in years). Costs of leasehold improvements are amortized over the lesser of the term of the lease (including renewal option periods) or the estimated useful lives of the improvements.

Land improvements			15
Buildings and improvements			20 – 40
Leasehold improvements			10 – 20
Machinery and equipment			5 – 10
Dies and tools			3 – 5
Vehicles			3 – 5
Office equipment			3 – 10

Customer Lists, Patents, and Other Intangible Assets

The following table summarizes intangible assets by major category as of December 31, 2012 and 2011:

Amortization of intangible assets was $45,867, $48,020 and $51,808 in 2012, 2011 and 2010, respectively. During the fourth quarter of 2011, the Company wrote down its trade name indefinite-lived intangible asset. See the Goodwill and Other Indefinite-Lived Intangible Assets section for further discussion. Estimated amortization expense each year for the five years subsequent to December 31, 2012 is as follows: 2013, $24,084; 2014, $16,686; 2015, $15,480; 2016, $13,668; 2017, $10,328.

Debt Issuance Costs

Direct and incremental costs incurred in connection with the issuance of long-term debt are capitalized and amortized to interest expense over the terms of the related credit agreements. Debt discounts incurred in connection with the issuance of long-term debt are deferred and recorded as a reduction of outstanding debt and amortized to interest expense using the effective interest method over the terms of the related credit agreements. Approximately $3,759, $1,986, and $2,439 of deferred financing costs and original issue discounts were amortized to interest expense during fiscal years 2012, 2011 and 2010, respectively. Estimated amortization expense each year for the five years subsequent to December 31, 2012 is as follows: 2013, $5,105; 2014, $5,360; 2015, $5,634; 2016, $5,944; 2017, $5,960.

Long-Lived Assets

The Company periodically evaluates the carrying value of long-lived assets (excluding goodwill and trade names). Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the sum of the expected future undiscounted cash flows is less than the carrying amount of an asset, a loss is recognized for the difference between the fair value and carrying value of the asset. Such analyses necessarily involve significant judgments.

Goodwill and Other Indefinite-Lived Intangible Assets

Goodwill represents the excess of the purchase price over fair value of identifiable net assets acquired from business acquisitions. Goodwill is not amortized, but is reviewed for impairment on an annual basis and between annual tests if indicators of impairment are present. The Company conducts its annual impairment test for goodwill on October 31st of each year. Conditions that would trigger an impairment assessment include, but are not limited to, a significant adverse change in legal factors or business climate that could affect the value of an asset.

The Company uses a two-step process to test for goodwill impairment. First, the reporting unit's fair value is compared to its carrying value. Fair value is estimated using a combination of qualitative analyses, a discounted cash flow approach and a market approach. If a reporting unit's carrying amount exceeds its fair value, an indication exists that the reporting unit's goodwill may be impaired, and the second step of the impairment test would be performed. The second step of the goodwill impairment test is used to measure the amount of the potential impairment loss. In the second step, the implied fair value of the reporting unit's goodwill is determined by allocating the reporting unit's fair value to all of its assets and liabilities other than goodwill in a manner similar to a purchase price allocation. The implied fair value of the goodwill that results from the application of this second step is then compared to the carrying amount of the goodwill and an impairment charge would be recorded for the difference if the carrying value exceeds the implied fair value of the goodwill.

The Company performed the required annual impairment tests for fiscal years 2012, 2011 and 2010 and found no impairment of goodwill. There can be no assurance that future goodwill impairment tests will not result in a charge to earnings.

The changes in the carrying amount of goodwill for the years ended December 31, 2012 and 2011 are as follows:

	Year ended December 31, 2012										Year ended December 31, 2011
	Gross			Accumulated Impairment				Net Goodwill			Gross			Accumulated Impairment				Net Goodwill
Balance at beginning of year		$	1,050,666		$	(503,193	)		$	547,473		$	1,030,341		$	(503,193	)		$	527,148
Acquisition of a business, net			5,470			—				5,470			20,325			—				20,325
Balance at end of year		$	1,056,136		$	(503,193	)		$	552,943		$	1,050,666		$	(503,193	)		$	547,473

The Company acquired two businesses during fiscal 2012 for a combined purchase price of $47,044, net of cash acquired, which resulted in additional goodwill of $5,545. Separately, the Magnum purchase price allocation was finalized during the third quarter of 2012, which resulted in an adjustment to goodwill of $(75). The Company acquired one business during fiscal 2011 for $85,490, net of cash acquired and inclusive of estimated earn-out payments. This resulted in additional goodwill of $20,337. Offsetting this increase in goodwill was a $(12) adjustment to goodwill recorded during the second quarter of 2011 due to finalization of the purchase price allocation from a 2010 acquisition. A majority of goodwill amounts are deductible for tax purposes.

Other indefinite-lived intangible assets consist of trade names. The Company tests the carrying value these trade names by comparing the assets fair value to its carrying value. Fair value was measured using a relief-from-royalty approach, which assumes the fair value of the trade name is the discounted cash flows of the amount that would be paid had the Company not owned the trade name and instead licensed the trade name from another company. The Company conducts its annual impairment test for indefinite-lived intangible assets on October 31st of each year.

The Company performed the required annual impairment tests for fiscal years 2012 and 2010 and found no impairment of indefinite-lived trade names. During the fourth quarter of 2011, the Company decided to strategically transition certain products to their more widely known Generac brand. Based on this decision, the Company recorded a $9,389 non-cash trade name impairment charge as of October 31, 2011 which primarily related to the write down of the impacted trade name to net realizable value. There can be no assurance that future impairment tests will not result in a charge to earnings.

Income Taxes

The Company is a C Corporation and, therefore, accounts for income taxes pursuant to the liability method. Accordingly, the current or deferred tax consequences of a transaction are measured by applying the provision of enacted tax laws to determine the amount of taxes payable currently or in future years. Deferred income taxes are provided for temporary differences between the income tax bases of assets and liabilities and their carrying amounts for financial reporting purposes. In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the years in which those temporary differences become deductible. The Company considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies, as appropriate, in making this assessment.

Revenue Recognition

Sales, net of estimated returns and allowances, are recognized upon shipment of product to the customer, which is when title passes, the Company has no further obligations, and the customer is required to pay. The Company, at the request of certain customers, will warehouse inventory billed to the customer but not delivered. Unless all revenue recognition criteria have been met, the Company does not recognize revenue on these transactions until the customers take possession of the product. The funds collected on product warehoused for these customers are recorded as a customer advance until the customer takes possession of the product and the Company's obligation to deliver the goods is completed. Customer advances are included in accrued liabilities in the accompanying consolidated balance sheets.

The Company provides for certain estimated sales promotion and incentive expenses which are recognized as a reduction of sales.

Historically, product returns, whether in the normal course of business or resulting from repurchases made under a floor plan financing program, have not been material.

Shipping and Handling Costs

Shipping and handling costs billed to customers are included in net sales, and the related costs are included in cost of goods sold in the consolidated statements of comprehensive income.

Advertising and Co-Op Advertising

Expenditures for advertising, included in selling and service expenses in the accompanying consolidated statements of comprehensive income, are expensed as incurred. Total expenditures for advertising were $13,360, $11,742, and $11,985 for the years ended December 31, 2012, 2011, and 2010, respectively.

Research and Development

The Company expenses research and development costs as incurred. Total expenditures incurred for research and development were $23,499, $16,476, and $14,700 for the years ended December 31, 2012, 2011 and 2010, respectively.

Foreign Currency Translation and Transactions

Foreign currency balance sheet accounts are translated into dollars at the rates of exchange in effect at fiscal year-end. Income and expenses incurred in a foreign currency are translated at the average rates of exchange in effect during the year. The related translation adjustments are made directly to a separate component of Stockholders' Equity.

Realized and unrealized gains and losses on transactions denominated in foreign currency are generally recorded in earnings as a component of cost of goods sold.

Accumulated Other Comprehensive Loss

Accumulated other comprehensive loss includes foreign currency translation adjustments, pension liability adjustments and unrealized losses on certain cash flow hedges. The components of accumulated other comprehensive loss at December 31, 2012 and 2011 were:

	December 31,
	2012			2011
Foreign currency translation adjustments	$	(34	)	$	-
Pension liability, net of tax of $(4,174) and $(3,173)		(12,081	)		(10,529	)
Unrealized losses on cash flow hedges, net of tax of $(109) and $(440)		(2,381	)		(4,828	)
Accumulated other comprehensive loss	$	(14,496	)	$	(15,357	)

Fair Value of Financial Instruments

The Company believes the carrying amount of its financial instruments (cash and cash equivalents, 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, was approximately $913,191 (level 2) at December 31, 2012, as calculated based on independent valuations whose inputs and significant value drivers are observable.

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 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 are prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities.

Assets and liabilities measured at fair value on a recurring basis are as follows:

	Fair Value Measurement Using
	Total December 31, 2012			Quoted Prices in Active Markets for Identical Contracts (Level 1)		Significant Other Observable Inputs (Level 2)
Interest rate swaps	$	(2,973	)	$	–	$	(2,973	)
Commodity contracts	$	111		$	–	$	111

	Fair Value Measurement Using
	Total December 31, 2011			Quoted Prices in Active Markets for Identical Contracts (Level 1)		Significant Other Observable Inputs (Level 2)
Interest rate swaps	$	(5,268	)	$	–	$	(5,268	)
Commodity Contracts	$	(373	)	$	–	$	(373	)

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. Excluding the impact of credit risk, the fair value of derivatives at December 31, 2012 and 2011 was $2,936 (liability) and $5,780 (liability), respectively, and this represents the amount the Company would need to pay to exit the agreements on this date.

Use of Estimates

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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Derivative Instruments and Hedging Activities

The Company records all derivatives in accordance with ASC 815, Derivatives and Hedging, 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, the Company 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. These are intended to offset the effect of price fluctuations on actual inventory purchases. There were one, two, and one outstanding commodity contracts in place to hedge its projected commodity purchases at December 31, 2012, 2011, and 2010, respectively. In October 2009, the Company entered into commodity swaps to purchase $1,432 of copper. The swaps were effective from October 5, 2009, and terminated on March 31, 2010. In November 2010, the Company entered into a commodity swap to purchase $2,296 of copper. The swap was effective from January 1, 2011, and terminated on April 30, 2011. In February 2011, the Company entered into a commodity forward contract to purchase a notional amount of $2,378 of copper. The contract was effective from March 1, 2011, and terminated on December 31, 2011. In March 2011, the Company entered into a commodity forward contract to purchase a notional amount of $2,100 of copper. The contract was effective from April 1, 2011, and terminated on December 31, 2011. In May 2011, the Company entered into a commodity forward contract to purchase a notional amount of $1,808 of copper. The contract was effective from May 5, 2011, and terminated on December 31, 2011. In September 2011, the Company entered into two new commodity forward contracts to purchase notional amounts of $4,533 and $1,935 of copper. The contracts are effective from October 1, 2011, and terminate on June 30, 2012. In May 2012, the Company entered into a commodity forward contract to purchase a notional amount of $1,898 of copper. The contract was effective from July 1, 2012, and terminated on December 31, 2012. In October 2012, the Company entered into a commodity forward contract to purchase a notional amount of $3,472 of copper. The contract was effective from January 1, 2013, and terminates on September 30, 2013.

Total losses or gains recognized in the consolidated statements of operations on commodity contracts were a gain of $386, a loss of $861, and a gain of $1,056 for the years ended December 31, 2012, 2011, and 2010, respectively.

Foreign Currencies

The Company is exposed to foreign currency exchange risk as a result of transactions 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 one year or less. There were no foreign currency hedge contracts outstanding as of December 31, 2012, 2011 or 2010. There was one Euro currency contract outstanding during 2010 that expired on December 31, 2010. A loss of $100 was recognized in the consolidated statements of operations for the year ended December 31, 2010 related to this Euro contract.

Interest Rates

The Company has two interest rate swap agreements outstanding as of December 31, 2012 with a notional amount of $300,000. The Company had four interest rate swap agreements outstanding as of December 31, 2011 with a notional amount of $300,000. In 2010, the Company entered into two interest rate swap agreements and 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. The first was entered into on January 21, 2010. The effective date of this swap was July 1, 2010 with a notional amount of $200,000, a fixed LIBOR rate of 1.73% and an expiration date of July 1, 2012. The second was entered into on June 29, 2010. The effective date of that swap was October 1, 2010 with a notional amount of $100,000, a fixed LIBOR rate of 1.025% and an expiration date of October 1, 2012. The Company entered into two interest rate swap agreements on April 1, 2011. The effective date of the first swap is July 1, 2012 with a notional amount of $200,000, a fixed LIBOR rate of 1.905% and an expiration date of July 1, 2013. The effective date of the second swap is 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. 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. Beginning May 31 2012, the effective portion of the swaps prior to the change (i.e. amounts previously recorded in Accumulated Other Comprehensive Loss) have been and will continue to be amortized as interest expense over the period of the originally designated hedged transactions which have various dates through October 2013. Future changes in fair value of these swaps have been and will continue to be immediately recognized in the consolidated statements of comprehensive income as interest expense.

The following table presents the fair value of the Company's derivatives:

	December 31, 2012			December 31, 2011
Derivatives designated as hedging instruments:
Interest rate swaps	$	-		$	(5,268	)
		-			(5,268	)
Derivatives not designated as hedging instruments:
Commodity contracts		111			(373	)
Interest rate swaps		(2,973	)		-
Total derivatives	$	(2,862	)	$	(5,641	)

The fair value of all derivatives not designated as hedging instruments is included in other current liabilities and other assets in the consolidated balance sheets as of December 31, 2012 and 2011, respectively.

The fair value of derivatives designated as hedging instruments included in other current liabilities and other long-term liabilities is $1,546 and $3,722, respectively, as of December 31, 2011.

The fair value of the derivative contracts considers the Company's credit risk as of December 31, 2012 and 2011. The impact of credit risk on the fair value of derivative contracts at December 31, 2012 and 2011 was $74 and $139, respectively. Excluding the impact of credit risk, the fair value of the derivatives at December 31, 2012 and 2011 was $2,936 (liability) and $5,780 (liability), respectively, and this 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 consolidated statement of comprehensive income for the year ended December 31, 2012, 2011 and 2010:

	Amount of gain (loss) recognized in AOCI for the twelve months ended December 31,								Location of gain (loss) recognized in net income (loss) on ineffective portion of hedges	Amount of loss reclassified from AOCI into net income (loss) for the twelve months ended December 31,							Amount of gain (loss) recognized in net income (loss) on hedges (ineffective portion) for twelve months ended December 31,

Stock-Based Compensation

Stock-based compensation expense, including stock options and restricted stock awards, is generally recognized on a straight-line basis over the vesting period based on the fair value of awards which are expected to vest. The fair value of all share-based awards is estimated on the date of grant.

Segment Reporting

The Company operates in and reports as a single operating segment, which is the design and manufacture of a wide range of power products. Net sales are predominantly generated through the sale of generators and other engine powered products through various distribution channels. The Company manages and evaluates its operations as one segment primarily due to similarities in the nature of the products, production processes and methods of distribution. The Company's sales in the United States represent approximately 93%, 95%, and 95% of total sales for the years ended December 31, 2012, 2011 and 2010, respectively. Approximately 98%, 100% and 100% of the Company's identifiable long-lived assets are located in the United States as of December 31, 2012, 2011 and 2010, respectively.

The Company's product offerings consist primarily of power products with a range of power output geared for varying end customer uses. Residential power products and commercial & industrial power products are each a similar class of products based on similar power output and end customer usage. The breakout of net sales between residential, commercial & industrial, and other products is as follows:

	Year ended December 31,
	2012		2011		2010
Residential power products	$	705,444	$	491,016	$	372,782
Commercial & industrial power products		410,341		250,270		183,555
Other		60,521		50,690		36,543
Total	$	1,176,306	$	791,976	$	592,880

New Accounting Pronouncements

In December 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2011-12, "Comprehensive Income (Topic 220): Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05". In June 2011, the FASB issued ASU 2011-05, "Comprehensive Income (Topic 220): Presentation of Comprehensive Income". Both ASU's are effective for annual reporting periods beginning after December 15, 2011, and both were adopted by the Company as of January 1, 2012. ASU 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders' equity. In addition, items of other comprehensive income that are reclassified to profit or loss are required to be presented separately on the face of the financial statements. This guidance is intended to increase the prominence of other comprehensive income in financial statements by requiring that such amounts be presented either in a single continuous statement of income and comprehensive income or separately in consecutive statements of income and comprehensive income. ASU 2011-12 defers the changes in ASU 2011-05 that pertain to how, when and where reclassification adjustments are presented. The Company's adoption of these standards did not have a material impact on the consolidated financial statements.

In July 2012, the FASB issued ASU 2012-02, "Intangibles- Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment". This standard is effective for annual and interim indefinite-lived intangible asset impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted. This standard provides for an optional qualitative assessment for the testing of indefinite-lived intangible asset impairment to determine whether it is more likely than not that such asset is impaired. If it is concluded that this is the case, it is necessary to perform the currently prescribed quantitative impairment test by comparing the fair value of the indefinite-lived intangible asset with its carrying value. Otherwise, the quantitative impairment test is not required. The Company's adoption of this standard is not expected to have a material impact on the consolidated financial statements.

There are several other new accounting pronouncements issued by the FASB. Each of these pronouncements, as applicable, has been or will be adopted by the Company. Management does not believe any of these accounting pronouncements has had or will have a material impact on the Company's consolidated financial statements.

Acquisitions [Abstract]

Acquisitions

3. Acquisitions

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 a preliminary estimate of acquired working capital. This estimate will be finalized in 2013 to reflect actual working capital acquired, which will result in a change in the total purchase price. This acquisition was funded solely by existing cash.

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 2012 consolidated financial statements include the results of Ottomotores from December 8, 2012 through December 31, 2012. In addition, transaction costs of approximately $1,062 are included in other expense in the consolidated statement of comprehensive income for the year ended December 31, 2012.

Acquisition of GenTran

On February 1, 2012, a subsidiary of the Company acquired substantially all of the assets and assumed certain liabilities of a leading transfer switch and portable generator accessory manufacturer ("GenTran") for a purchase price, net of cash acquired of $2,275. The purchase price allocation was finalized during the second quarter of 2012, and the Company recorded $1,200 of intangible assets, including approximately $495 of goodwill, as of the acquisition date. The goodwill ascribed to this acquisition is deductible for tax purposes. The acquisition is not material to the Company's consolidated financial statements.

Acquisition of Magnum

On October 3, 2011, a subsidiary of the Company acquired substantially all of the assets and assumed certain liabilities of Magnum Products, LLC and certain of its affiliates (collectively, Magnum) for a purchase price, net of cash acquired and inclusive of estimated earn-out payments, of approximately $85,490. The acquisition was funded solely by existing cash.

Magnum is a supplier of generator powered light towers, mobile generators and combination power units for a variety of industries and specialties including construction, energy, mining, government, military, and special events. Its products are distributed through international, national and regional equipment rental companies, equipment dealers and construction companies. The Magnum business is a strategic fit for the Company as it provides diversification within the existing business, with the introduction of new engine powered products and distribution channels, while also providing opportunities for future revenue and cost synergies.

The purchase price of $85,490 consisted of $83,907 paid in cash at closing and $1,583 recorded as an estimated liability to the sellers for contingent consideration based upon future performance of a particular product line currently in development, as described below. The cash paid at closing included an estimate of acquired working capital. This estimate was finalized in 2012 to reflect actual working capital acquired, resulting in a $75 negative adjustment to the $20,337 of goodwill recorded for this transaction during the fourth quarter of 2011. The goodwill ascribed to this acquisition is deductible for tax purposes.

The Company recorded a purchase price allocation during the fourth quarter of 2011 based on a fair value appraisal by a third party valuation firm. A summary of the fair values assigned to the acquired assets is as follows:

Accounts receivable	$	24,309
Inventory		23,763
Prepaid expenses and other current assets		280
Property and equipment		5,164
Goodwill		20,337
Trade name		17,740
Customer relationships		14,740
Patents		1,070
Other intangible assets		2,220
Trade accounts payable		(20,727	)
Accrued expenses		(2,746	)
Other long term liabilities		(2,243	)
Total cash paid, net of $30 cash acquired	$	83,907

Under the acquisition agreement, the purchase price may be increased based upon the performance of a particular product line for the years 2012 through the second quarter of 2017. Based on performance projections available at the date of the acquisition, the Company recorded estimated contingent consideration of $1,583 which is the net present value of the estimated earn-out. The contingent consideration is payable periodically during 2012 through 2017, based upon actual future performance. As of December 31, 2011, there had been no changes to our original estimates. Due primarily to the accretion from the passage of time, the contingent consideration liability balance increased to $1,656 as of December 31, 2012.

The 2011 consolidated financial statements include the results of Magnum from October 3, 2011 through December 31, 2011. The acquisition contributed $38,817 and $3,353 of net sales and net income, respectively, for the period from October 3, 2011 to December 31, 2011. The 2012 consolidated financial statements include the results of Magnum for the full year. Transaction costs of approximately $876 are included in other expense in the consolidated statement of comprehensive income for the year ended December 31, 2011.

The following unaudited pro forma information has been prepared as if the Magnum acquisition had been consummated at January 1, 2010. This information is presented for informational purposes only, and is not necessarily indicative of the operating results that would have occurred if the acquisitions had been consummated as of that date. This information should not be used as a predictive measure of our future financial position, results of operations, or liquidity.

On February 11, 2013, the Company made an $80,000 voluntary prepayment of debt with available cash on hand that was applied to both the required excess cash flow payment and all required future principal amortizations. The Company classified this portion of debt as a current liability in the consolidated balance sheet at December 31, 2012.

For all years presented, the Company had credit agreements which provided for borrowings under a revolving credit facility (the Revolving Credit Facility), and term loans (collectively, the Credit Agreements), which are described further below. The Credit Agreements of the Company were secured by the associated collateral agreements which pledged virtually all assets of the Subsidiary.

On February 9, 2012, a subsidiary of the Company (the "Borrower" or "Generac Power Systems") entered into a new 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 outstanding in 2011 and 2010 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") with certain commercial banks and other lenders. The Term Loan Credit Agreement provides for a $900,000 term loan B credit facility ("Term Loan") and a $125,000 uncommitted incremental term loan facility. The Term Loan Credit Agreement matures on May 30, 2018. Proceeds from the Term Loan were used to repay the Company's previous Credit Agreement. The remaining proceeds from the Term Loan were used, along with cash on hand, to pay a special cash dividend of $6.00 per share on the Company's common stock (see Note #13 – Special Cash Dividend).

Concurrent with the closing of the Term Loan Credit Agreement, on May 30, 2012, the Borrower also entered into a new revolving credit agreement (the "ABL Credit Agreement") with certain commercial banks and other lenders. The ABL Credit Agreement provides for borrowings under a $150,000 senior secured ABL revolving credit facility (the "ABL Facility"). The size of the ABL Facility could increase by $50,000 pursuant to an uncommitted incremental credit facility. The ABL Credit Agreement matures May 30, 2017.

Borrowings under the ABL Facility are guaranteed by all of the Borrower's wholly-owned domestic restricted subsidiaries and the Parent, 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 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 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 ABL Credit Agreement) under the ABL Facility is less than the greater of (i) 10.0% of the lesser of the aggregate commitments and the applicable borrowing base under the ABL Facility or (ii) $10,000. The ABL Credit Agreement also contains covenants and events of default substantially similar to those in the Term Loan Credit Agreement, as described below. The Company is required to pay an ABL Facility commitment fee of 0.50% on the average available unused commitment. As of December 31, 2012, the Company had $147,036 of availability under the ABL facility, net of outstanding letters of credit. As of December 31, 2012, the Company's interest rate on the ABL Facility was 1.96%. There were no borrowings outstanding under the ABL Facility as of December 31, 2012.

The ABL Credit Agreement provides the Company the ability to issue letters of credit. Outstanding undrawn letters of credit reduced availability under the Company's ABL Facility. The letters of credit accrued interest at a rate of 1.88%, paid quarterly on the undrawn daily aggregate exposure of the preceding quarter. This rate is subject to meeting certain financial ratios. At December 31, 2012 and 2011, letters of credit outstanding were $2,964 and $5,809, and interest rates were 1.88% and 2.13% respectively.

As of December 31, 2012, short-term borrowings primarily consisted of borrowings by our foreign subsidiaries on local lines of credit, which totaled $12.5 million at a weighted average interest rate of approximately 2.20%.

The Term Loan is guaranteed by all of the Borrower's wholly-owned domestic restricted subsidiaries and the Parent, 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 are secured by a second priority lien.

The Term Loan amortizes in equal installments of 0.25% of the original principal amount of the Term Loan payable on the first day of April, July, October and January commencing on October 1, 2012 until the maturity date of the Term Loan. The final principal repayment installment of the Term Loan is required to be repaid on the maturity date in an amount equal to the aggregate principal amount of the Term Loan outstanding on such date. In February 2013, the Borrower made an $80.0 million debt prepayment that was applied to all required future principal amortizations. The Term Loan initially bears interest at rates 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%. At December 31, 2012 and 2011 the Company's interest rate was 6.25% and 2.80%, respectively.

The Term Loan Credit Agreement restricts the circumstances in which the Borrower can pay distributions and dividends, which are in addition to those to be paid in connection with the Transactions (as defined in the Term Loan Credit Agreement). 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 Term Loan Credit Agreement restricts the aggregate amount of dividends and distributions that can be paid and, in certain circumstances, requires Pro Forma (as defined in the Term Loan Credit Agreement) compliance with certain fixed charge coverage ratios in order to pay certain dividends or distributions. The Term Loan Credit Agreement also contains certain other affirmative and negative covenants that, among other things, provide limitations on 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 the Company's organizational documents. The Term Loan Credit Agreement does not contain any financial maintenance covenants. The Company was in compliance with all requirements of the Credit Agreements as of December 31, 2012, 2011 and 2010.

The 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 (as defined in the Term Loan Credit Agreement). A bankruptcy or insolvency event of default causes such obligations to automatically become immediately due and payable.

Prior to entering into the new credit agreement on February 9, 2012, and the subsequent amendment and restatement on May 30, 2012 the Company had (i) a first lien credit facility with Goldman Sachs Credit Partners L.P., as administrative agent, composed of (x) a $950,000 term loan, which was scheduled to mature in November 2013 and (y) a $150,000 revolving credit facility, which was scheduled to mature in November 2012, and (ii) a second lien credit facility with JP Morgan Chase Bank, N.A., as administrative agent, composed of a $430,000 term loan, which was scheduled to mature in May 2014.

The principal amount of and the outstanding balance under the Term Loan was $881,268 and $597,874, net of loans held in treasury by the Company, at December 31, 2012 and 2011, respectively. In addition to scheduled principal payments, the Term Loan requires an excess cash flow payment each year. The required excess cash flow payment is the amount by which 50% of the excess cash flow (as defined in the credit agreement) generated by the Company in any given year exceeds the principal payments made during that year, subject to certain leverage ratio requirements. The excess cash flow payment is scheduled to be due 125 days after year-end. For the year ending December 31, 2012, based on the calculation, including voluntary prepayments made prior to the excess cash flow payment date, the Company was not required to make an excess cash flow payment. For the year ending December 31, 2011, as a result of refinancing the Credit Agreement on February 9, 2012, the Company was not required to make an excess cash flow payment. For the year ending December 31, 2010, based on the calculation, the Company was not required to make an excess cash flow payment.

In 2010, the Company used net proceeds from its initial public offering and a substantial portion of its cash and cash equivalents to pay down debt. In February 2010, the Company used $221,622 in net proceeds from the initial public offering to pay down the second lien term loan in full and to pay down a portion of the first lien term loan. In addition, in March 2010, December 2010, April 2011, December 2011 and February 2012 the Company used $138,495, $74,194, $24,731, $34,624 and $22,874 respectively, of cash and cash equivalents on hand to further pay down principal.

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 interest rate 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. Beginning May 31 2012, the effective portion of the swaps prior to the change (i.e. amounts previously recorded in Accumulated Other Comprehensive Loss) have been and will continue to be amortized as interest expense over the period of the originally designated hedged transactions which have various dates through October 2013. Future changes in fair value of the swaps have been and will continue to be immediately recognized in the condensed consolidated statements of comprehensive income as interest expense.

Redeemable Stock and Stockholders' Equity (Deficit)

Redeemable Stock and Stockholders' Equity (Deficit) [Abstract]

Redeemable Stock and Stockholders' Equity (Deficit)

7. Redeemable Stock and Stockholders' Equity (Deficit)

Between November 2006 and February 2010, certain of the current equity investors (affiliates of CCMP Capital Advisors, LLC and related entities, certain other investors, certain members of management of the Subsidiary and board of directors of the Company) had previously acquired a combination of Class A and Class B Common stock and Series A Preferred stock of the Company. General terms of these securities are:

Preferred stock

Series A Convertible Preferred stock: Each Series A Preferred share was entitled to a priority return preference equal to the sum of $10,000 per share base amount plus an amount sufficient to generate a 14% annual return on that base amount compounded quarterly from the date of issuance until the accreted priority return preference was paid in full. Each Series A Preferred share also participated in any equity appreciation beyond the Series A Preferred priority return (the Series A Equity Participation).

Voting: Series A Preferred shares did not have voting rights, subject to certain limited approval rights.

Distributions: Dividends and other distributions to stockholders in respect of shares, whether as part of an ordinary distribution of earnings, as a leveraged recapitalization or in the event of an ultimate liquidation and distribution of available corporate assets were to be paid to Series A Preferred stockholders as follows: Series A Preferred shares were entitled to receive an amount equal to the Series A Preferred base amount of $10,000 per share plus an amount sufficient to generate a 14% annual return on that base amount, compounded quarterly from the date in which the Series A Preferred shares were originally issued. Series A Preferred shares were then entitled to receive an equity participation on all remaining proceeds after payment of this priority return to all Series A Preferred stockholders equal to 24.3% of remaining proceeds (Series A Equity Participation). No distribution would be made to any holder of common stock until the Series A Preferred stockholders had received all distributions to which they were entitled as previously described. After such distributions were made to the Series A Preferred stockholders, the holders of common stock were entitled to receive any remaining payments or distributions in accordance with their respective priorities.

Liquidations: Distributions in connection with any liquidation or change of control transaction would be made in accordance with the distributions described above. No distribution would be made to any holder of common stock until the Series A Preferred stockholders had received all distributions to which they were entitled as described above. After such distributions were made to the Series A Preferred stockholders, the holders of common stock would be entitled to receive any remaining payments or distributions in accordance with their respective priorities.

Conversion: Series A Preferred shares automatically converted into Class A common shares at the time of the initial public offering (IPO). Any unpaid Series A preferred return (base $10,000 per share plus 14% accretion) was converted into additional Class A common shares valued at the IPO price net of underwriter's discount. That is, each Series A Preferred share was converted into a number of Class A common shares equal to (i) a fraction, the numerator of which is the unpaid priority return on such Series A Preferred share and the denominator of which is the value of a Class A common share at the time of conversion plus (ii) the number of Class A common shares required to be issued to satisfy the Series A Equity Participation. The number of shares of Class A common stock which were issued upon conversion of the Series A Preferred was dependent upon the initial public offering price of the Class A common stock on the date of conversion as well as the unpaid priority return of the Series A Preferred stock.

The Series A Preferred were redeemable in a deemed liquidation in the event of a change of control. The redemption features were considered to be outside the control of the Company and therefore, all shares of Series A Preferred stock were recorded outside of permanent equity in accordance with guidance originally issued under EITF Topic D-98, Classification and Measurement of Redeemable Securities (codified under Accounting Standards Codification 480, Distinguishing Liabilities from Equity). Until the time of the IPO, no adjustment to the carrying value of the Series A Preferred stock securities had been recorded, and the priority returns had not been accreted as a change of control was not probable.

Common stock

Class B Convertible common stock: Class B shares participated in the equity appreciation after the Series A Preferred priority return was satisfied. Each Class B share was entitled to a priority return preference equal to the sum of $10,000 per share base amount plus an amount sufficient to generate a 10% annual return on that base amount compounded quarterly from the date of issue until the Class B priority return preference is paid in full. Each Class B share also participated in any equity appreciation beyond the Class B priority return.

Voting: Each Class B share was entitled to one vote per share on all matters on which stockholders voted.

Class A common stock: Class A shares participated in the equity appreciation after the Class B priority return was satisfied.

Class A shares did not have voting rights, priority preference or any accretion rights.

Distributions: After payment of the priority return to Series A Preferred stockholders previously described above under Preferred Stock, dividends and other distributions that remain available to stockholders in respect of shares, whether as part of an ordinary distribution of earnings, as a leveraged recapitalization or in the event of an ultimate liquidation and distribution of available corporate assets, were to be paid to the common stockholders as follows: Class B shares were entitled to receive an amount equal to the Class B base amount of $10,000 per share plus an amount sufficient to generate a 10% annual return on that base amount, compounded quarterly from the date in which the Class B shares were originally issued. After payment of this priority return to Class B holders, the holders of Class A shares and Class B shares participated together equally and ratably in any and all distributions by the Company.

Liquidations: Distributions made in connection with any liquidation or change of control transaction would be made in accordance with the distributions previously described above in the preceding paragraph. In addition, any remaining assets after the Class B preferential distribution would be allocated to the Class A and Class B shares as follows: the Class B shares would receive a percentage of the remaining assets equal to the sum of (i) 88% plus (ii) the product of (A) 12% multiplied by (B) one minus a fraction, the numerator of which is the number of issued and outstanding vested shares of Class A shares and the denominator is 9,350.0098. The remainder would be allocated to the Class A shares.

Conversion: Class B shares automatically converted into Class A shares immediately prior to the IPO. Any unpaid Class B Common priority return (base $10,000 per share plus 10% accretion) was "paid" in additional Class A common shares valued at the IPO price net of underwriter's discount. That is, each Class B share converted into a number of Class A shares required to be issued to satisfy the Class B Common priority return. Each Class B share converted into a number of Class A shares equal to (i) one plus (ii) a fraction, the numerator of which was the unpaid priority return on such Class B share and the denominator of which was the value of a Class A share at the time of conversion, in all cases subject to the priority rights and preferences of the Series A Preferred Shares. The number of shares of Class A common stock which were issued upon conversion of the Class B common stock was dependent upon the initial public offering price of the Class A common stock on the date of conversion as well as the unpaid priority return of the Class B common stock.

The Class B common were redeemable in a deemed liquidation in the event of a change of control. The redemption features were considered to be outside the control of the Company and therefore, all shares of Class B common stock were recorded outside of permanent equity in accordance with guidance originally issued under EITF Topic D-98, Classification and Measurement of Redeemable Securities (codified under Accounting Standards Codification 480, Distinguishing Liabilities from Equity). Until the time of the IPO, no adjustment to the carrying value of Class B Common stock securities had been recorded, and the priority returns had not been accreted as a change of control was not probable.

Accretion: Cumulative accretion on Series A preferred stock and Class B common stock at the time of the IPO on February 17, 2010, was as follows:

	Series A Preferred		Class B Common
Carrying value	$	113,109	$	765,096
Cumulative accretion		17,006		286,299
	$	130,115	$	1,051,395

The amounts above do not include the additional base amount of $25,790 on Class B common stock or the impact of Series A Equity Participation of $114,900 on Series A Preferred stock, both of which were recognized as a beneficial conversion at the time of the initial public offering.

The Company determined that the conversion feature in the Class B Common stock was in-the-money at the date of issuance and therefore represented a beneficial conversion feature. Since the Class B Common stock was convertible upon an initial public offering, the beneficial conversion was contingent upon a future event and had not been recorded in the consolidated financial statements prior to the IPO. The beneficial conversion feature, which was valued at $25,790 at its commitment date, was recorded at the completion of the IPO on February 10, 2010 as a return to Class B Common stockholders analogous to a dividend. Since no retained earnings were available to pay this dividend at resolution of the contingency, the dividend was charged against additional paid in capital resulting in no net impact.

Management Equity Incentive Plan: On November 10, 2006, the Company adopted the 2006 Management Equity Incentive Plan (2006 Equity Incentive Plan). The 2006 Equity Incentive Plan provided for awards with respect to a maximum of 9,350.0098 Class A Common shares and 5,000 Class B Common shares, subject to certain adjustments. On November 10, 2006, and from time to time thereafter, certain members of management purchased restricted shares of Class A Common stock under the 2006 Equity Incentive Plan for $341 per share and pursuant to restricted stock agreements. One half of the restricted shares vested over time (Time Vesting Shares), with 25% vesting on November 10, 2007 and on the next three anniversaries thereafter, so long as the participant was still employed by the Company or one of its subsidiaries on the applicable vesting date. Upon the occurrence of a change of control of the Company, any unvested Time Vesting Shares immediately vested in full, so long as the participant was still employed by the Company or one of its subsidiaries. The other half of the restricted shares immediately vested (performance-based vesting) in full, provided the participant was still then employed by the Company or one of its subsidiaries, upon the occurrence of either: (i) a change of control of the Company that provides CCMP with a certain rate of return with respect to net proceeds received by CCMP from their investment in the Company; or (ii) from and after the date of an IPO, the achievement with respect to shares of the Class A Common stock of an average closing trading price exceeding, in any 60 consecutive trading day period starting prior to the later of (a) the fifth year anniversary of the date of grant of the restricted shares, and (b) one year after the IPO, a certain threshold with respect to net proceeds received by CCMP from their investment in the Company. As a condition to the purchase of restricted shares, members of management executed confidentiality, non-competition and intellectual property agreements.

The fair value of the Class A common stock on the date of issuance was estimated to be $390 per share. The Company recorded $6, and $38, and $40 of stock-based compensation expense related to the Time Vesting Shares in 2010, 2009, and 2008, respectively, related to amortization of the excess of fair value over purchase price of these restricted shares. This excess was being amortized over the vesting provisions of the restricted shares. As a result of the IPO, the remaining unvested performance-based Restricted Shares became fully vested. As a result, the Company has recorded $159 of stock-based compensation expense related to the accelerated vesting in 2010.

Issuance and repurchases of securities

Series A Preferred Stock: In September 2009, the Company issued 2,000 shares of the Series A Preferred stock to CCMP and certain members of management and the board of directors, for an aggregate purchase price of $20,000. In December 2009, the Company issued an aggregate of 1,476 shares of Series A Preferred stock to CCMP in exchange for certain term loans under the first and second lien credit facilities that CCMP had purchased. The exchange ratio in connection with the exchange was one share of Series A Preferred stock per $10 of the amount paid by CCMP for the loans that were so exchanged. Such purchased term loans had a cumulative outstanding principal amount equal to $154,815. As the equity consideration was less than the outstanding principal amount, a gain on debt extinguishment was recorded.

The Company determined that the conversion feature in the Series A Preferred stock had a contingent beneficial conversion feature at the date of issuance. The Series A Preferred stock was convertible upon an initial public offering and the number of additional Class A Common shares which may be issued was unknown prior to the IPO. Since the beneficial conversion was contingent upon a future event, it had not been recorded in the consolidated financial statements prior to the IPO. The $114,900 beneficial conversion feature, which is the result of the additional Class A shares issued to satisfy the Series A Equity Participation, was recorded at the completion of the initial public offering on February 10, 2010, as a return to Series A Preferred stockholders analogous to a dividend. Since no retained earnings were available to pay this dividend at resolution of the contingency, the dividend was charged against additional paid in capital resulting in no net impact.

Earnings Per Share

Earnings Per Share [Abstract]

Earnings Per Share

8. Earnings Per Share

In fiscal years 2012, 2011 and 2010, basic earnings per share is calculated by dividing net income by the weighted average number of shares outstanding. Except where the result would be anti-dilutive, diluted 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:

	Year ended December 31 ,
	2012		2011		2010
Net income	$	93,223	$	324,643	$	56,913
Less: accretion of Series A Preferred stock		-		-		(2,042	)
Less: accretion of Class B Common stock		-		-		(12,133	)
Less: beneficial conversion		-		-		(140,690	)
Net income (loss) attributable to Common stock (formerly Class A Common stock)		93,223		324,643		(97,952	)
Income attributable to Class B Common stock		-		-		12,133

Net income (loss) per common share - basic:
Common stock (formerly Class A Common stock)	$	1.38	$	4.84	$	(1.65	)
Class B Common stock		n/a		n/a	$	505

Net income (loss) per common share - diluted:
Common stock (formerly Class A Common stock)	$	1.35	$	4.79	$	(1.65	)
Class B Common stock		n/a		n/a	$	505

Weighted average number of shares outstanding – Common Stock (formerly Class A Common stock):
Basic		67,360,632		67,130,356		59,364,958
Dilutive effect of equity awards (1)		1,832,506		667,015		-
Diluted		69,193,138		67,797,371		59,364,958

Weighted average number of shares outstanding – Class B Common stock – basic and diluted:		n/a		n/a		24,018

(1) Excludes approximately 363,000 stock options and restricted stock awards for the twelve month period ended December 31, 2012, as the impact of such awards was anti-dilutive. There were no anti-dilutive awards for the twelve month period ended December 31, 2011. For the year ended December 31, 2010, diluted earnings per share are identical to basic earnings per share because the impact of common stock equivalents on earnings per share is anti-dilutive. Had the impact not been anti-dilutive, the effect of stock compensation awards on weighted average diluted shares outstanding would have been 257,038.

In fiscal year 2010, the Company's Class B Common stock was considered a participating stock security requiring use of the "two-class" method for the computation of basic net income (loss) per share in accordance with provisions of ASC 260-10 Earnings per share. Losses were not allocated to the Class B Common stock in the computation of basic earnings per share as the Class B Common stock was not obligated to share in losses. Basic earnings per share excludes the effect of common stock equivalents and was computed using the "two-class" computation method, which subtracts earnings attributable to the Class B preference from total earnings. In addition, earnings attributable to the Series A Preferred preference and the Class B and Series A Preferred beneficial conversion were subtracted from total earnings. Any remaining loss was attributed to the Class A Common shares.

Income Taxes

9. Income Taxes

The Company's provision for income taxes consists of the following:

	Year ended December 31,
	2012			2011			2010
Current:
Federal	$	34,170		$	14,312		$	–
State		3,854			1,885			307
Foreign		81			–			–
		38,105			16,197			307
Deferred:
Federal		21,972			15,632			19,127
State		3,048			1,887			2,831
Foreign		25			–			–
		25,045			17,519			21,958
Change in valuation allowance		(21	)		(271,393	)		(21,958	)
Provision for income taxes	$	63,129		$	(237,677	)	$	307

The Company is the taxpaying entity and files a consolidated federal income tax return. Currently, the Company is not under examination by any major taxing jurisdiction to which the Company is subject. The statute of limitation for tax years 2012, 2011, 2010, and 2009 is open, for federal and state income taxes. Additionally, tax years 2007 and 2008 remain open for examination by certain state and foreign taxing authorities.

Significant components of deferred tax assets and liabilities are as follows:

	December 31,
	2012			2011
Deferred tax assets:
Goodwill and intangible assets	$	125,457		$	160,311
Accrued expenses		26,606			16,572
Deferred revenue		3,503			1,370
Inventories		2,544			2,720
Pension obligations		9,064			8,641
Stock-based compensation		6,408			5,302
Operating loss and credit carryforwards		24,915			50,429
Interest rate swap, copper derivative		1,119			2,065
Other		36			719
Valuation allowance		(806	)		–
Total deferred tax assets		198,846			248,129

Deferred tax liabilities:
Depreciation		12,274			5,994
Prepaid expenses		1,131			377
Total deferred tax liabilities		13,405			6,371
Net deferred tax asset	$	185,441		$	241,758

The net current and noncurrent components of deferred taxes included in the consolidated balance sheets are as follows:

	December 31,
	2012			2011
Net current deferred tax assets	$	48,687		$	14,395
Net long-term deferred tax assets		137,560			227,363
Valuation allowance		(806	)		–
Net deferred tax assets	$	185,441		$	241,758

The Company was in a three year cumulative net loss position, due primarily to a 2008 goodwill and tradename impairment write-off, and therefore had not considered expected future taxable income in analyzing the realizability of the deferred tax assets as of December 31, 2010, resulting in a full valuation allowance against these net deferred tax assets. In the fourth quarter of 2011, the Company was no longer in a three-year cumulative loss position and, as part of the normal assessment of the future realization of the net deferred tax assets, determined that a valuation allowance was no longer required. As a result, the valuation allowance was reversed in the fourth quarter of 2011 and the Company recorded as a tax benefit of $271,393.

Acquired as part of the Ottomotores acquisition, Ottomotores Brazil generated net operating losses for multiple years. The realizability of the deferred tax assets associated with these net operating losses is uncertain so a valuation allowance has been recorded in the opening balance sheet as of December 8, 2012.

At December 31, 2012, the Company has federal net operating loss carryforwards of approximately $54,079, which expire between 2028 and 2030, and various state net operating loss carryforwards, which expire between 2017 and 2030.

As a result of ownership changes, Section 382 of the Internal Revenue Code of 1986 as amended and similar state provisions can limit the annual deductions of net operating loss and tax credit carry forwards. Such annual limitations could result in the expiration of net operating loss and tax credit carry forwards before utilization. The Company has no such limitation as of December 31, 2011 and expects no limitation was triggered in 2012. Future ownership changes may result in such a limitation. However, the Company believes any limitation would not be significant.

At December 31, 2012 and 2011, the Company has no reserves recorded for uncertain tax positions.

A reconciliation of the statutory tax rates and the effective tax rates for the years ended December 31, 2012, 2011 and 2010 are as follows:

	Year ended December 31,
	2012			2011			2010
U.S. statutory rate		35.0	%		35.0	%		35.0	%
State taxes		4.1			4.0			4.0
Valuation allowance		-			(312.3	)		(38.0	)
Other		1.3			-			-
Effective tax rate		40.4	%		(273.3	)%		1.0	%

The American Taxpayer Relief Act of 2012 (the "Act") was signed into law on January 2, 2013. The Act retroactively restored several expired business tax provisions, including the research and experimentation credit. Because a change in tax law is accounted for in the period of enactment, the retroactive benefit of the Act on the Company's U.S. federal taxes for 2012 will be recognized in 2013. The Company expects the Act's extension of this provision through the end of 2013 will reduce our estimated annual effective tax rate for 2013, however we do not believe the effect will be material.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Benefit Plans [Abstract]

Benefit Plans

10. Benefit Plans

Medical and Dental Plan

The Company maintains medical and dental benefit plans covering full-time employees of the Company and their dependents. Certain plans are partially or fully self-funded plans under which participant claims are obligations of the plan. These plans are funded through employer and employee contributions at a level sufficient to pay for the benefits provided by the plan. The Company's contributions to the plan were $8,741, $6,700, and $7,300 for the years ended December 31, 2012, 2011, and 2010, respectively. The plan covering a majority of full-time employees maintains individual stop loss insurance policies on the medical portion with a limit of stop loss of $235 to mitigate losses. Balances for the incurred but not yet reported claims, including reported but unpaid claims at December 31, 2012, and 2011, were $1,185 and $800, respectively. The Company estimates claims incurred but not yet reported based on its historical experience. During 2012, the Company paid premiums of $2,446 for other standard medical benefits covering certain full-time employees.

Savings Plan

The Company maintains a defined-contribution 401(k) savings plan for virtually all domestic employees who meet certain eligibility requirements. Under the plan, employees may defer receipt of a portion of their eligible compensation.

The Company amended the 401(k) savings plans effective January 1, 2009, to add Company matching and non-elective contributions. The Company may contribute a matching contribution of 50% of the first 6% of eligible compensation of employees. No matching contribution shall be made with respect to employee catch-up contributions. The Company may contribute a non-elective contribution for each plan year after 2008. The contribution will apply to eligible employees employed on December 31, 2008. The rate of the non-elective contribution is determined based upon years of service as of December 31, 2008, and is fixed. Both Company matching contributions and non-elective contributions are subject to vesting. Forfeitures may be applied against plan expenses.

The Company recognized $3,000, $2,400 and $2,300 of expense related to this plan in 2012, 2011 and 2010, respectively.

Pension Plans

The Company has noncontributory salaried and hourly pension plans (collectively, "Pension Plans") covering certain domestic employees. The benefits under the salaried plan are based upon years of service and the participants' defined final average monthly compensation. The benefits under the hourly plan are based on a unit amount at the date of termination multiplied by the participant's years of credited service. The Company's funding policy for the Pension Plans is to contribute amounts at least equal to the minimum annual amount required by applicable regulations. The Company elected to freeze the Pension Plans effective December 31, 2008. This resulted in a cessation of all future benefit accruals for both hourly and salary pension plans.

The Company uses a December 31 measurement date for the Pension Plans. Information related to the Pension Plans is as follows:

	Year Ended December 31,
	2012			2011
Accumulated benefit obligation at end of period	$	59,744		$	53,467

Amounts recognized in accumulated other comprehensive income
Net actuarial loss	$	(12,081	)	$	(10,529	)

The actuarial loss for the Pension Plans that was amortized from OCI into net periodic benefit cost during 2012 is $909. The amount in OCI as of December 31, 2012 that is expected to be recognized as a component of net periodic pension expense during the next fiscal year is $1,108.

Additional information related to the Pension Plans is as follows:

	Year ended December 31,
	2012			2011			2010
Components of net periodic pension expense:
Interest cost	$	2,453		$	2,369		$	2,359
Expected return on plan assets		(2,398	)		(2,342	)		(2,004	)
Amortization of net loss		909			273			247
Net periodic pension expense	$	964		$	300		$	602

Weighted-average assumptions used to determine benefit obligation are as follows:

	December 31,
	2012			2011
Discount rate – salaried pension plan		4.10	%		4.65	%
Discount rate – hourly pension plan		4.14	%		4.65	%
Rate of compensation increase (1)		n/a			n/a

(1)	No compensation increase was assumed as the plans were frozen effective December 31, 2008.

Weighted-average assumptions used to determine net periodic pension expense are as follows:

	Year ended December 31,
	2012			2011			2010
Discount rate		4.65	%		5.23	%		5.76	%
Expected long-term rate of return on plan assets		7.57			7.62			7.30
Rate of compensation increase (1)		n/a			n/a			n/a

(1)	No compensation increase was assumed as the plans were frozen effective December 31, 2008.

To determine the long-term rate of return assumption for plan assets, the Company studies historical markets and preserves the long-term historical relationships between equities and fixed-income securities consistent with the widely accepted capital market principle that assets with higher volatility generate a greater return over the long run. The Company evaluates current market factors such as inflation and interest rates before it determines long-term capital market assumptions and reviews peer data and historical returns to check for reasonableness and appropriateness.

The Pension Plan's weighted-average asset allocation at December 31, 2012 and 2011, by asset category, is as follows:

				December 31, 2012					December 31, 2011
Asset Category	Target			Dollars		%			Dollars		%
Fixed Income		24	%		8,736		24	%		7,349		23	%
Domestic equity		49	%		17,926		49	%		15,879		51	%
International equity		17	%		6,257		17	%		4,766		15	%
Real estate		10	%		3,651		10	%		3,429		11	%
Total		100	%	$	36,570		100	%	$	31,423		100	%

The fair values of the Pension Plan's assets at December 31, 2012 are as follows:

	Total		Quoted prices in active markets for identical asset (level 1)		Significant observable inputs (level 2)		Significant unobservable inputs (level 3)
Mutual fund	$	33,683	$	33,683	$	–	$	–
Collective trust		2,887		–		2,887		–
Total	$	36,570	$	33,683	$	2,887	$	–

The fair values of the Pension Plan's assets at December 31, 2011 are as follows:

	Total		Quoted prices in active markets for identical asset (level 1)		Significant observable inputs (level 2)		Significant unobservable inputs (level 3)
Mutual fund	$	28,530	$	28,530	$	–	$	–
Collective trust		2,893		–		2,893		–
Total	$	31,423	$	28,530	$	2,893	$	–

Mutual Funds – This category includes investments in mutual funds that encompass both equity and fixed income securities that are designed to provide a diverse portfolio. The plan's mutual funds are designed to track exchange indices, and invest in diverse industries. Some mutual funds are classified as regulated investment companies. Investment managers have the ability to shift investments from value to growth strategies, from small to large capitalization funds, and from U.S. to international investments. These investments are valued at the closing price reported on the active market on which the individual securities are traded. These investments are classified within Level 1 of the fair value hierarchy.

Collective Trusts – This category includes public investment vehicles valued using the Net Asset Value (NAV) provided by the administrator of the trust. The NAV is based on the value of the underlying assets owned by the trust, minus its liabilities, and then divided by the number of shares outstanding. The NAV of the trust is classified within Level 2 of the fair value hierarchy.

The Company's target allocation for equity securities and real estate is generally between 65% – 85%, with the remainder allocated primarily to bonds. The Company regularly reviews its actual asset allocation and periodically rebalances its investments to the targeted allocation when considered appropriate.

The Company expects to make estimated contributions of $1,052 to the Pension Plans in 2013.

The following benefit payments are expected to be paid from the Pension Plans:

Year
2013	$	1,656
2014		1,768
2015		1,863
2016		1,994
2017		2,191
Years 2018 – 2022	$	12,715

Share Plans [Abstract]

Share Plans

11. Share Plans

On November 10, 2006, the Company adopted the 2006 Management Equity Incentive Plan (2006 Equity Incentive Plan). The 2006 Equity Incentive Plan provided for awards with respect to a maximum of 9,350.0098 shares of Common stock (formerly Class A Common stock) and 5,000 Class B Common shares, subject to certain adjustments. On November 10, 2006, and from time to time thereafter, certain members of management purchased restricted shares of Class A Common stock under the 2006 Equity Incentive Plan for $341 per share and pursuant to restricted stock agreements. One half of the restricted shares vested over time (Time Vesting Shares), with 25% vesting on November 10, 2007 and on the next three anniversaries thereafter, so long as the participant was still employed by the Company or one of its subsidiaries on the applicable vesting date. Upon the occurrence of a change of control of the Company, any unvested Time Vesting Shares immediately vested in full, so long as the participant was still employed by the Company or one of its subsidiaries. The remaining restricted shares immediately vested (performance-based vesting) in full, provided the participant was still then employed by the Company or one of its subsidiaries, upon the occurrence of either: (i) a change of control of the Company that provides CCMP with a certain rate of return with respect to net proceeds received by CCMP from their investment in the Company; or (ii) from and after the date of an IPO, the achievement with respect to shares of the Common stock (formerly Class A Common stock) of an average closing trading price exceeding, in any 60 consecutive trading day period starting prior to the later of (a) the fifth year anniversary of the date of grant of the restricted shares, and (b) one year after the IPO, a certain threshold with respect to net proceeds received by CCMP from their investment in the Company. As a condition to the purchase of restricted shares, members of management executed confidentiality, non-competition and intellectual property agreements.

The fair value of the Class A common stock on the date of issuance was estimated to be $390 per share. The Company recorded $6 of stock-based compensation expense related to the Time Vesting Shares in 2010 related to amortization of the excess of fair value over purchase price of these restricted shares. This excess was being amortized over the vesting provisions of the restricted shares. As a result of the IPO, the remaining unvested performance-based Restricted Shares became fully vested. As a result, the Company recorded $159 of stock-based compensation expense related to the accelerated vesting in 2010.

The Company adopted an equity incentive plan on February 10, 2010 in connection with the IPO. At the time of the IPO, 4,341,504 stock options and 456,249 shares of restricted stock and other stock awards were granted to employees and Board members of the Company pursuant to the equity incentive plan. The Company has subsequently granted an additional 470,372 stock options and 287,618 shares of restricted stock and other stock awards to employees and Board members of the Company. Total share-based compensation cost related to the equity incentive plan recognized in the consolidated statements of comprehensive income was $10,780, $8,646 and $6,198 in 2012, 2011 and 2010, respectively, net of actual forfeitures, which is recorded in operating expenses in the consolidated statements of comprehensive income.

Stock Options - Stock options granted in 2012 have an exercise price of between $18.82 per share and $37.05 per share, stock options granted in 2011 have an exercise price of between $11.15 per share and $18.73 per share, and the stock options granted in 2010 have an exercise price of between $7.00 per share and $10.18 per share. On June 29, 2012, the Company used a portion of the proceeds from the May 30, 2012 debt refinancing (see footnote #6 – Credit Agreement) together with cash on its balance sheet to pay a special cash dividend of $6.00 per share on its common stock. 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 options as of the special dividend date was adjusted by the $6.00 special dividend amount. There was no change to compensation expense as a result of this adjustment. On July 2, 2012, the strike price of all stock option awards outstanding prior to the special dividend date was restated to reflect these adjustments. The exercise prices noted above reflect this adjustment. Stock options issued in 2012 vest in equal installments over four years, subject to the grantee's continued employment or service and expire 10 years after the date of grant. Stock options issued in 2011 and 2010 vest in equal installments over five years, subject to the grantee's continued employment or service and expire 10 years after the date of grant.

Beginning in 2011, stock option exercises are net-share settled such that the Company withholds shares with value equivalent to the exercise price of the awards plus the employees' minimum statutory obligation for the applicable income and other employment taxes. Total shares withheld were approximately 667,041 and 55,202 in 2012 and 2011, respectively, and were based on the value of the stock on the exercise date as determined based upon an average of the Company's high and low stock sales price. Total payments for the employees' tax obligations to the taxing authorities were $6,425, $371 and $0 in 2012, 2011 and 2010, respectively, and are reflected as a financing activity within the Consolidated Statement of Cash Flows. The net-share settlements had the effect of share repurchases by the Company as they reduced the number of shares that would have otherwise been issued as a result of the vesting and did not represent an expense to the Company.

The Company has agreed to pay these taxes on behalf of the employees in return for the employee exchanging an equivalent value of options to the Company. This transaction resulted in a decrease of approximately $6,425 and $371 in 2012 and 2011, respectively, to equity on the consolidated balance sheet as the cash payment of the taxes effectively acted as a repurchase of the stock options previously granted.

The grant-date fair value of each option grant is estimated using the Black-Scholes-Merton option pricing model. The fair value is then amortized on a straight-line basis over the requisite service period of the awards, which is generally the vesting period. Use of a valuation model requires management to make certain assumptions with respect to selected model inputs. Since there is limited history for the Company's stock, expected volatility is calculated based on an analysis of historic and implied volatility measures for a set of peer companies. The average expected life is based on the contractual term of the option using the simplified method. The risk-free interest rate is based on U.S. Treasury zero-coupon issues with a remaining term equal to the expected life assumed at the date of grant. The compensation expense recognized is net of estimated forfeitures. Forfeitures are estimated based on termination history, as there is not sufficient history of actual share option forfeitures at this time. The weighted-average assumptions used in the Black-Scholes-Merton option pricing model for 2012 and 2011 are as follows:

	2012			2011
Weighted average grant date fair value	$	12.13		$	11.10

Assumptions:
Expected stock price volatility		45	%		50	%
Risk free interest rate		1.22	%		2.69	%
Expected annual dividend per share	$	0.00		$	0.00
Expected life of options (years)		6.25			6.5

The Company periodically evaluates its forfeiture rates and updates the rates it uses in the determination of its stock-based compensation expense. The impact of the change to the forfeiture rates on non-cash compensation expense was immaterial for the years ended December 31, 2012, 2011 and 2010. A summary of the Company's stock option activity and related information for the three years ended December 31, 2012 is as follows:

	Number of Options	Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (in years)		Aggregate Intrinsic Value ($ in thousands)
Outstanding as of December 31, 2009	-	$	-
Granted	4,366,504		13.02

Exercisable as of December 31, 2012	509,054	$	13.19	7.3	$	10,750

Of the 1,113,827 stock options exercised during the fiscal year 2012, 667,041 shares underlying such exercised options were retained by the Company in a net-share settlement to cover the aggregate exercise price and the required amount of employee withholding taxes.

As of December 31, 2012, there was $16,356 of total unrecognized compensation cost, net of expected forfeitures, related to unvested options. The cost is expected to be recognized over the remaining service period, having a weighted-average period of 2.4 years. Total share-based compensation cost related to the stock options for 2012, 2011 and 2010 was $6,835, $6,475 and $4,470, respectively, which is recorded in operating expenses in the consolidated statements of comprehensive income.

Restricted Stock – For awards issued prior to 2012, restricted stock awards vest in full on the third anniversary of the date of grant, subject to the grantee's continued employment. Restricted stock awards issued in 2012 vest in equal installments over three years, subject to the grantee's continued employment or service. The fair market value of the award at the time of the grant is amortized to expense over the period of vesting. The fair value of restricted share awards is determined based on the market value of the Company's shares on the grant date. The compensation expense recognized for restricted share awards is net of estimated forfeitures.

A summary of the Company's restricted share awards activity for the three years ended December 31, 2012 is as follows:

Non-vested Stock Awards	Shares	Weighted-Average Grant-Date Fair Value
Non-vested as of December 31, 2009	-	$	-
Granted	439,999		13.02
Vested	-		-
Forfeited	(9,844)		(13.00)
Non-vested as of December 31, 2010	430,155	$	13.02
Granted	59,147		20.59
Vested	-		-
Forfeited	-		-
Non-vested as of December 31, 2011	489,302	$	13.93
Granted	195,771		26.94
Vested	-		-
Forfeited	(20,002)		-
Non-vested as of December 31, 2012	665,071	$	17.75

As of December 31, 2012, there was $4,431 of total unrecognized compensation cost, net of expected forfeitures, related to non-vested stock awards. That cost is expected to be recognized over the remaining service period, having a weighted-average period of 2.0 years. Total share-based compensation cost related to the restricted stock for 2012, 2011 and 2010 was $3,645, $1,871 and 1,447, respectively, which is recorded in operating expenses in the consolidated statements of comprehensive income.

Special Cash Dividend	12 Months Ended
Special Cash Dividend	Dec. 31, 2012
Special Cash Dividend [Abstract]
Special Cash Dividend	13. Special Cash Dividend On June 29, 2012, the Company used a portion of the proceeds from the May 30, 2012 debt refinancing (see Note #6 – Credit Agreements) together with cash on its balance sheet to pay a special cash dividend of $6.00 per share on its common stock, resulting in payments totaling $404,332 to stockholders. Dividends declared but unpaid as of December 31, 2012 of $3,957, which relate to dividends earned on unvested restricted stock awards, are included in other accrued liabilities in the consolidated balance sheet. In connection with the special dividend, and pursuant to the terms of the Company's stock option plan, certain adjustments were 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, on July 2, 2012, the strike price for all outstanding stock options at that time was modified by the $6.00 special dividend amount. There was no change to compensation expense as a result of this adjustment. Dividends have been recorded as a reduction to additional paid-in capital as the Company has an accumulated deficit balance.

Covenant description		The ABL Facility 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 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 ABL Credit Agreement) under the ABL Facility is less than the greater of (i) 10.0% of the lesser of the aggregate commitments and the applicable borrowing base under the ABL Facility or (ii) $10,000. The ABL Credit Agreement also contains covenants and events of default substantially similar to those in the Term Loan Credit Agreement, as described below. The Company was required to pay an ABL Facility commitment fee of 0.50% on the average available unused commitment. As of December 31, 2012, the Company had $147,036 of availability under the ABL facility, net of outstanding letters of credit.As of December 31, 2012, the Company's interest rate on the ABL Facility was 1.96%. There were no borrowings outstanding under the ABL Facility as of December 31, 2012.

Excludes approximately 363,000 stock options and restricted stock awards for the twelve month period ended December 31, 2012, as the impact of such awards was anti-dilutive. There were no anti-dilutive awards for the twelve month period ended December 31, 2011. For the year ended December 31, 2010, diluted earnings per share are identical to basic earnings per share because the impact of common stock equivalents on earnings per share is anti-dilutive. Had the impact not been anti-dilutive, the effect of stock compensation awards on weighted average diluted shares outstanding would have been 257,038.
