6.	Common Stock Repurchases

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 26, 2016, we repurchased and cancelled 7,460 shares of common stock for $0.4 million at an average price of $48.23 per share. During the fifty-two weeks ended December 26, 2015, we repurchased and cancelled 33,430 shares of common stock for $1.6 million at an average price of $48.14 per share.

Our Board of Directors has authorized a share repurchase program up to $150 million through December 31, 2016. Under this program, share repurchases may be made from time to time depending on market conditions, share price, share availability and other factors at our discretion. The share repurchase program does not obligate us to acquire any specific number of shares. For the thirteen weeks ended March 26, 2016, we repurchased and cancelled 207,166 shares of common stock for $9.6 million at an average price of $46.46 per share under this program. For the fifty-two weeks ended December 26, 2015, we repurchased and cancelled 747,700 shares of common stock for $35.7 million at an average price of $47.77 per share under this program.
