These guidelines also limit the amount of credit exposure to any one issue, issuer or type of instrument. As of January 25, 2009, we were in compliance with our investment policy.  As of January 25, 2009, our investments in government agencies and government sponsored enterprises represented approximately 71% of our total investment portfolio, while the financial sector, which has been negatively impacted by recent market liquidity conditions, accounted for approximately 17% of our total investment portfolio. Substantially all of our investments are with A/A2 or better rated securities with the substantial majority of the securities rated AA-/Aa3 or better.  



    We performed an impairment review of our investment portfolio as of January 25, 2009. Currently, we have the intent and ability to hold our investments with impairment indicators until maturity. Based on our quarterly impairment review and having considered the guidance in Statement of Financial Accounting Standards Staff Position No. 115-1, or FSP No. 115-1, A Guide to the Implementation of Statement 115 on Accounting for Certain Investments in Debt and Equity Securities, we recorded other than temporary impairment charges of $9.9 million during fiscal year 2009. These charges include $5.6 million related to what we believe is an other than temporary impairment of our investment in the money market funds held by the Reserve International Liquidity Fund, Ltd., or International Reserve Fund; $2.5 million related to a decline in the value of publicly traded equity securities and $1.8 million related to debt securities held by us that were issued by companies that have filed for bankruptcy as of January 25, 2009.   Please refer to Note 17 of the Notes to the Consolidated Financial Statements in Part IV, Item 15 of this Form 10-K for further details.

As of January 27, 2008, we had a net unrealized gain of $10.7 million, which was comprised of gross unrealized gains of $11.1 million, offset by $0.4 million of gross unrealized losses.
