8.            Income Taxes

The provision for income taxes for the three months ended August 26, 2012 was $1.5 million.  The effective tax rate for the three months ended August 26, 2012 was 37 percent, compared to 38 percent for the first quarter of fiscal year 2012. The effective tax rate for the three months ended August 26, 2012 differs from the statutory federal income tax rate of 35 percent as a result of several factors, including state taxes, domestic manufacturing deductions, non-deductible stock-based compensation expense and the benefit of state research and development credits.  

As of May 27, 2012, the Company had unrecognized tax benefits of approximately $766,000.  Included in the balance of unrecognized tax benefits as of May 27, 2012 is approximately $593,000 of tax benefits that, if recognized, would result in an adjustment to the Company’s effective tax rate. The Company expects its unrecognized tax benefits to change by $8,000 within the next twelve months related to the expiration of tax attributes.

In accordance with accounting guidance, the Company has decided to classify interest and penalties related to uncertain tax positions as a component of its provision for income taxes.  The Company has accrued an insignificant amount of interest and penalties relating to the income tax on the unrecognized tax benefits as of August 26, 2012 and May 27, 2012.

Due to tax attribute carry forwards, the Company is subject to examination for tax years 1996 and later for U.S. tax purposes.  The Company was also subject to examination in various state jurisdictions for tax years 1998 and later, none of which were individually significant.
