Investments   Our investment portfolio is comprised of short-term and long-term investments. Investments classified as short-term available-for-sale consist primarily of municipal bonds, corporate bonds and variable demand notes. Investments classified as long-term available-for-sale consist of auction rate securities, whose underlying assets are student loans.   Our investments in available-for-sale securities are recorded at estimated fair value on our financial statements, and the temporary differences between cost and estimated fair value are presented as a separate component of accumulated other comprehensive loss.   As of April 2, 2011, we had gross unrealized gains before tax from our investment in municipal bonds, corporate bonds and variable demand notes of $0.4 million offset by gross unrealized losses of $0.1 million and gross unrealized losses on our auction rate securities of $2.9 million.  As of January 1, 2011, we had gross unrealized gains before tax from our investment in municipal bonds, corporate bonds and variable demand notes of $0.6 million offset by gross unrealized losses of $0.1 million and gross unrealized losses on our auction rate securities of $3.3 million.   The aggregate market value, cost basis and net unrealized gains and losses of available-for-sale investments as of April 2, 2011 and as of January 1, 2011 by major security type are as follows:   <table style="WIDTH: 100%;

The assets underlying these investments are student loans backed by the U.S. government under the Federal Family Education Loan Program or by private insurers and are rated between BBB and AAA. Historically, these securities have provided liquidity through a Dutch auction process that resets the applicable interest rate periodically every seven to thirty-five days. Beginning in February of 2008, these auctions began to fail. The principal amount of these auction rate securities will not be accessible until future auctions for these securities are successful, a secondary market is established, these securities are called for redemption, or they are paid at maturity.   As of April 2, 2011, we had recorded an estimated cumulative unrealized loss of $2.9 million ($1.7 million, net of tax) related to the temporary impairment of the auction rate securities, which was included in accumulated other comprehensive income (loss) within shareholders equity. In addition, our management reviews impairments and credit loss associated with its investments, including auction rate securities, to determine the classification of the impairment as temporary or other-than-temporary and to bifurcate the credit and non-credit component of an other-than-temporary impairment event. We (i) do not intend to sell any of the auction rate securities prior to maturity at an amount below the original purchase value; (ii) intend to hold the investment to recovery and, based on a more-likely-than-not probability assessment, will not be required to sell the security before recovery; and (iii) deem that it is not probable that we will receive less than 100% of the principal and accrued interest from the issuer. Therefore, 100% of the impairment was charged to other comprehensive income (loss). Our auction rate securities are classified as long-term and are valued at $19.7 million using significant unobservable inputs. Further, we continue to liquidate investments in auction rate securities as opportunities arise. During the three months ended April 2, 2011, we liquidated $2.1 million of our auction rate securities as they were called at par.   If the issuers of the auction rate securities are unable to successfully complete future auctions and their credit ratings deteriorate, we may in the future be required to record an impairment charge to earnings on these investments. It could conceivably take until the final maturity of the underlying notes (up to 30 years) to realize the investments carrying value.   Our deferred compensation plan includes our corporate owned life insurance policies and mutual fund investments.  The aggregate value of our deferred compensation plan as of April 2, 2011 and January 1, 2011 were as follows:   <table style="WIDTH: 73.34%;
