	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 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 thirteen weeks ended March 29, 2014 are not necessarily indicative of the results that may be expected for the fiscal year ending December 27, 2014. 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 28, 2013.

	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 recorded $3.6 million in goodwill and other intangible assets, all of which are expected to be deductible for tax purposes. The financial results of the acquired business have been included in the Consolidated Financial Statements since the acquisition date.

	3	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. Pursuant to these agreements, we sold $124.1 million and $89.0 million of accounts receivable during the thirteen weeks ended March 29, 2014 and March 30, 2013, respectively. If receivables had not been sold, $287.1 million and $267.8 million of additional accounts receivable would have been outstanding at March 29, 2014 and December 28, 2013, respectively, based on standard payment terms. Selling, general and administrative expenses for the thirteen weeks ended March 29, 2014 and March 30, 2013 included $1.5 million and $1.0 million, respectively, in financing costs associated with these accounts receivable sales programs.

	5	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 shares of restricted stock, incentive stock options and non-qualified stock options 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 and stock options are exercisable upon the terms set forth in the grant agreement approved by the Board of Directors, 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 March 29, 2014, 1,703,636 shares were available for grant under the Plan.
	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 and in certain circumstances, the attainment of financial goals. We retain the restricted stock, and any dividends paid thereto, until the vesting conditions have been met. For awards with a service condition only, compensation cost related to restricted stock is recognized on a straight-line basis over the vesting period. For awards that have a service condition and require the attainment of financial goals, compensation cost related to restricted stock is recognized over the vesting period if it is probable that the financial goals will be attained. Compensation cost related to restricted stock was $0.5 million and $0.2 million for the thirteen weeks ended March 29, 2014 and March 30, 2013, respectively.
	The following table summarizes our restricted stock activity for the thirteen weeks ended March 29, 2014:
			Shares			Weighted
						Average
						Price
	Balance at December 28, 2013			109,459		$	24.47
	Granted			21,190		$	52.37
	Vested			(9,000	)	$	10.94
	Balance at March 29, 2014			121,649		$	30.32
	As of March 29, 2014, there was approximately $2.8 million of unrecognized compensation cost related to nonvested restricted stock, which is expected to be recognized over a weighted-average period of approximately 2 years.
	Cash flows resulting from tax deductions in excess of the tax effect of compensation cost recognized in the financial statements are classified as financing cash flows. The excess tax benefit generated from restricted shares which vested in the thirteen weeks ended March 29, 2014 was $0.1 million and was credited to additional paid-in capital.
	We grant stock options to certain employees and members of the Board of Directors. We expense the grant-date fair value of employee stock options. Compensation cost is recognized on a straight-line basis over the vesting period for which related services are performed. The compensation cost charged against income for the thirteen weeks ended March 29, 2014 and March 30, 2013 was less than $0.1 million in each period. The compensation costs were classified as selling, general and administrative expense in the Consolidated Statements of Income. No cost was capitalized during fiscal 2014 or fiscal 2013.
	No stock options were granted in fiscal 2014 or fiscal 2013. Historically, we have used the Black-Scholes option valuation model to estimate the fair value of stock options granted. Expected volatility and expected dividend yield were 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. We included a forfeiture assumption of 5.4% for fiscal 2014 and fiscal 2013 in the calculation of compensation cost.
	The following table summarizes our stock option activity for the thirteen weeks ended March 29, 2014:
			Shares			Weighted		Weighted Average		Aggregate
						Average		Remaining Term		Intrinsic Value
						Price		(In years)
	Balance at December 28, 2013			141,500		$	7.13

	Balance at March 29, 2014			107,500		$	6.96		3.2	$	5,488,000
	Options exercisable at March 29, 2014			97,500		$	6.41		2.9	$	5,031,000
	The total intrinsic value of stock options exercised in the thirteen weeks ended March 29, 2014 was $1.6 million. As of March 29, 2014, there was approximately $0.1 million of unrecognized compensation cost related to non-vested stock options, which is expected to be recognized over a weighted-average period of approximately 1.4 years.
	Cash received from option exercises was approximately $0.3 million and $0.1 million in the thirteen weeks ended March 29, 2014 and March 30, 2013, respectively. The excess tax benefit generated from options which were exercised in the thirteen ended March 29, 2014 and March 30, 2013 was $0.1 million and $0.5 million, respectively, and was credited to additional paid-in capital.

Earnings Per Share	'
	6	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 calculated using the treasury stock method and are computed based on outstanding stock-based awards. However, in periods when the price of our stock-based awards, 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. No stock-based awards were considered anti-dilutive as of March 29, 2014 or March 30, 2013.
	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 thirteen weeks ended March 29, 2014, we repurchased and cancelled 17,210 shares of common stock at an average price of $57.30 per share. During the fifty-two weeks ended December 28, 2013, we repurchased and cancelled 78,580 shares of common stock at an average price of $44.39 per share.
	On December 12, 2013, we announced that our Board of Directors authorized the repurchase of up to $10 million of our outstanding common stock. Through March 29, 2014, we have repurchased and retired 3,600 shares at an average price of $50.60 per share.

	We have a non-cancelable operating lease for our primary operating facility with a partnership in which Steven L. Berman, our Chief Executive Officer, and his family members, are partners. Based upon the terms of the lease, payments will be approximately $1.5 million in fiscal 2014 and were $1.5 million in fiscal 2013. The lease with the partnership expires December 31, 2017. 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 March 29, 2014, we had $1.0 million of net unrecognized tax benefits, $0.8 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 March 29, 2014, 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 2009-2010. 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.
