Income Taxes

Note 14.  Income Taxes

Our effective tax rate for the thirteen and thirty-nine weeks ended January 25, 2013 was 35.2% and 36.6%, respectively, which was primarily due to our federal income tax rate of 35% plus state and foreign income taxes, the impact of the retroactive enactment of the Research and Development Tax Credit covering the period January 1, 2012 to January 25, 2013, which includes four months from the prior fiscal year 2012, and other permanent differences. Our effective tax rate for the thirteen and thirty-nine weeks ended January 27, 2012 was 40.2% and 40.2%, respectively, which was primarily due to our federal income tax rate of 35% plus state and foreign income taxes and the impact of shortfalls resulting from stock option exercises or cancellations and restricted stock vesting.
