Basis of Presentation	'
	1	Basis of Presentation
	As used herein, unless the context otherwise requires, “Dorman”, the “Company”, “we”, “us”, or “our” refers to Dorman Products, Inc. and its subsidiaries. Our ticker symbol on the NASDAQ Global Select Stock Market is “DORM”.
	The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the U.S. for interim financial information and in accordance with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). However, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the thirty-nine weeks ended September 28, 2013 are not necessarily indicative of the results that may be expected for the fiscal year ending December 28, 2013. We may experience significant fluctuations from quarter to quarter in our results of operations due to the timing of orders placed by our customers. Generally, the second and third quarters have the highest level of customer orders. The introduction of new products and product lines to customers may cause significant fluctuations from quarter to quarter. These financial statements should be read in conjunction with the consolidated financial statements and footnotes thereto included in our Annual Report on Form 10-K for the fiscal year ended December 29, 2012.
	The previously reported Consolidated Financial Statements include an adjustment to present accrued customer rebates which may be settled in cash as an accrued liability. The effect of this reclassification adjustment was a $6.4 million increase to accounts receivable and other accrued liabilities as of December 29, 2012. We believe the adjustment is inconsequential to any previous annual or interim Consolidated Financial Statements.

Acquisition	'
	2	Acquisition
	On May 17, 2013, we acquired certain assets and assumed certain liabilities of Re-Involt Technologies, LLC, a remanufacturer of hybrid battery systems, primarily to expand our product portfolio. The purchase price was approximately $3.7 million, comprised of $1.9 million in cash and $1.8 million of estimated contingent payments to the former owner. The contingent payment arrangement is based upon future earnings levels of the acquired business. In connection with this acquisition, we preliminarily recorded $3.6 million in goodwill and other intangible assets pending a final valuation of the assets and liabilities. All of the intangible assets resulting from the asset purchase are expected to be deductible for tax purposes. The financial results of the acquisition have been included in the Consolidated Financial Statements since the acquisition date.

	On September 21, 2011, we announced our plan to exit the international portion of our ScanTech business due to continued operating losses and to focus on growing our North American business. ScanTech was headquartered outside Stockholm, Sweden and distributed a line of Volvo and Saab replacement parts throughout the world.

	4	Sales of Accounts Receivable
	We have entered into several customer sponsored programs administered by unrelated financial institutions that permit us to sell certain accounts receivable at discounted rates to the financial institutions. Transactions under these agreements were accounted for as sales of accounts receivable and were removed from our Consolidated Balance Sheet at the time of the sales transactions. We do not service the receivables after the sales transactions. Pursuant to these agreements, we sold $296.5 million and $235.2 million of accounts receivable during the thirty-nine weeks ended September 28, 2013 and September 29, 2012, respectively. If receivables had not been sold, $226.1 million and $180.5 million of additional accounts receivable would have been outstanding at September 28, 2013 and December 29, 2012, respectively, based on standard payment terms. Selling, general and administrative expenses for the thirty-nine weeks ended September 28, 2013 and September 29, 2012 included $3.6 million and $3.3 million, respectively, in financing costs associated with these accounts receivable sales programs.

	6	Stock-Based Compensation
	Our 2008 Stock Option and Stock Incentive Plan (the “Plan”) was approved by our shareholders on May 20, 2009. Under the terms of the Plan, our Board of Directors may grant up to 2,000,000 shares of common stock in the form of incentive stock options, non-qualified stock options and shares of restricted stock or combinations thereof to officers, directors, employees, consultants and advisors. Grants under the Plan must be made within ten years of the date the Plan was approved. Stock options are exercisable upon the vesting date set forth in each stock option agreement but in no event more than ten years from the date of grant. Restricted stock vest in accordance with the terms set forth in each restricted stock agreement. At September 28, 2013, 1,703,326 shares were available for grant under the Plan.
	We expense the grant-date fair value of employee stock options. Compensation cost is recognized on a straight-line basis over the vesting period during which employees perform related services. The compensation cost charged against income for stock options for the thirty-nine weeks ended September 28, 2013 and September 29, 2012 was $119,000 and $151,000, respectively, before taxes. The compensation cost recognized is classified as selling, general and administrative expense in our Consolidated Statements of Operations. No compensation cost was capitalized during fiscal 2013 or fiscal 2012. We have included a forfeiture assumption of 5.4% for fiscal 2013 and fiscal 2012 in the calculation of compensation cost.
	We use the Black-Scholes option valuation model to estimate the fair value of stock options granted. Expected volatility and expected dividend yield are based on the actual historical experience of our common stock. The expected life represents the period of time that options granted are expected to be outstanding and was calculated using historical option exercise data. The risk-free rate was based on a U.S. Treasury security with terms equal to the expected time of exercise as of the grant date.
	The following table summarizes our stock option activity for the thirty-nine weeks ended September 28, 2013:
			Shares			Weighted		Weighted Average		Aggregate
						Average		Remaining Term		Intrinsic Value
						Price		(In years)
	Balance at December 29, 2012			274,000		$	8.62
	Exercised			(89,000	)	$	7.29
	Cancelled			(20,000	)	$	12.39
	Balance at September 28, 2013			165,000		$	8.6		4.4	$	6,778,000
	Options exercisable at September 28, 2013			115,000		$	6.57		3.4	$	4,957,000
	The total intrinsic value of stock options exercised in the thirty-nine weeks ended September 28, 2013 was $2.9 million. As of September 28, 2013, there was approximately $0.3 million of unrecognized compensation cost related to non-vested stock options, which is expected to be recognized over a weighted-average period of approximately 2.6 years.
	Cash received from option exercises and cash flows resulting from tax deductions in excess of compensation cost recognized in the financial statements are classified as cash flows from financing activities. Cash received from option exercises were approximately $0.5 million and $1.4 million in the thirty-nine weeks ended September 28, 2013 and September 29, 2012, respectively. The excess tax benefit generated from options which were exercised in the thirty-nine weeks ended September 28, 2013 and September 29, 2012 was $0.8 million and $2.4 million, respectively, and was credited to additional paid in capital.
	We grant restricted stock to certain employees and members of our Board of Directors. The value of restricted stock issued is based on the fair value of our common stock on the grant date. Vesting of restricted stock is conditional based on continued employment or service for a specified period. Compensation cost related to restricted stock is recognized on a straight-line basis over the vesting period. We retain the restricted stock, and any dividends paid thereto, until the vesting provisions have been met. Compensation cost related to restricted stock was $650,000 and $599,000 for the thirty-nine weeks ended September 28, 2013 and September 29, 2012, respectively.
	The following table summarizes our restricted stock activity for the thirty-nine weeks ended September 28, 2013:
			Shares			Weighted
						Average
						Price
	Balance at December 29, 2012			174,154		$	18.02

	Cancelled			(35,126	)	$	17.27
	Balance at September 28, 2013			125,278		$	23.55
	As of September 28, 2013, there was approximately $2.4 million of unrecognized compensation cost related to nonvested restricted stock, which is expected to be recognized over a weighted-average period of approximately 2.9 years. The excess tax benefit generated from restricted shares which were vested in the thirty-nine weeks ended September 28, 2013 was $0.3 million and was credited to additional paid in capital.

Earnings Per Share	'
	7	Earnings Per Share
	Basic earnings per share is calculated by dividing our net income by the weighted average number of common shares outstanding during the period, excluding nonvested restricted stock which is considered to be contingently issuable. To calculate diluted earnings per share, common share equivalents are added to the weighted average number of common shares outstanding. Common share equivalents are computed based on the number of outstanding stock options and nonvested restricted stock as calculated using the treasury stock method. However, in periods when the exercise price of our stock options, by grant, is greater than our average stock price during the period, those common share equivalents are considered anti-dilutive and are excluded from the calculation of diluted earnings per share. Options to purchase 50,000 shares of common stock were outstanding at September 29, 2012, but were excluded from the calculation of dilutive earnings per share as their effect would have been anti-dilutive.
	The following table sets forth the computation of basic earnings per share and diluted earnings per share:

	We periodically repurchase, at the then current market price, and cancel common stock issued to the Dorman Products, Inc. 401(k) Retirement Plan and Trust (the “401(k) Plan”). Shares are generally purchased from the 401(k) Plan when participants sell units as permitted by the 401(k) Plan or elect to leave the 401(k) Plan upon retirement, termination or other reasons. For the thirty-nine weeks ended September 28, 2013, we repurchased and cancelled 62,170 shares of common stock at an average price of $42.84 per share. During the fifty-two weeks ended December 29, 2012, we repurchased and cancelled 70,208 shares of common stock at an average price of $27.68 per share.

Based upon the terms of the lease, payments in fiscal 2013 will be $1.5 million. Total rental payments to the partnership under the lease arrangement were $1.5 million in fiscal 2012. The lease with the partnership expires December 31, 2017. Our Audit Committee is responsible for reviewing and approving all related party transactions. In the opinion of our Audit Committee, the terms and rates of this lease are no less favorable than those which could have been obtained from an unaffiliated party.

	At September 28, 2013, we had $1.6 million of net unrecognized tax benefits, $1.1 million of which would affect our effective tax rate if recognized. We recognize interest and penalties related to uncertain tax positions in income tax expense. As of September 28, 2013, we had approximately $0.2 million of accrued interest related to uncertain tax positions.
	We file income tax returns in the United States. All years before 2010 are closed for federal tax purposes. In regards to state tax, we are currently under examination by one state tax authority for the years 2008-2010. Tax years before 2009 are closed for the remaining states in which we file. We filed tax returns in Sweden through 2012 and all years prior to 2008 are closed. It is reasonably possible that audit settlements, the conclusion of current examinations or the expiration of the statute of limitations could impact the Company’s unrecognized tax benefits.

	12	New and Recently Adopted Accounting Pronouncements
	In June 2011, the Financial Accounting Standards Board (“FASB”) issued an update to its authoritative guidance which allows only two options for presenting the components of net income and other comprehensive income: (1) in a single continuous financial statement or (2) in two separate but consecutive financial statements. The guidance is effective in two stages. The requirement to present a single continuous statement or two separate but consecutive statements was effective for us beginning January 1, 2012. The second stage requires us to disclose the effects of reclassification adjustments from other comprehensive income to net income and was effective for us on December 30, 2012. For items reclassified in their entirety, we are required to disclose the effect of the reclassification on each line of net income that is affected by the reclassification adjustment. For items not reclassified in their entirety, we are required to add a cross reference to the financial statement disclosure that includes additional information about the effect of the reclassification. The adoption of these updates affect presentation only and therefore did not impact our results of operations, financial condition or cash flows.
	Other comprehensive loss of $2.8 million for the thirty-nine weeks ended September 29, 2012 is related to currency translation adjustments of our discontinued operation which is discussed in Note 3.
