Treasury Stock [Text Block]	NOTE 12. COMMON STOCK REPURCHASES From time to time, we acquire outstanding common stock in the open market to partially offset dilution from our equity award programs and to bring our cash to a more appropriate level for our company. On August 28, 2007, we announced the approval of a share repurchase plan (“2007 SRP”), which authorized the repurchase of up to $100 million of our common stock. As of March 27, 2011, we had purchased shares valued at $88.2 million under the 2007 SRP. During fiscal years 2013, 2012 and 2011, we did not repurchase any shares under the 2007 SRP. As of March 31, 2013, the remaining authorized amount for the stock repurchase under the 2007 SRP was $11.8 million. The 2007 SRP does not have a termination date. We may continue to utilize our 2007 SRP, which would reduce our cash, cash equivalents and/or short-term marketable securities available to fund future operations and to meet other liquidity requirements.
