Short-Term and Long-Term Investments	NOTE 6. Short-Term and Long-Term Investments Our short-term investments consist of highly-rated interest-bearing municipal bonds that have maturities that are less than one year and are accounted for as available for sale. As of the end of the first quarter of fiscal 2012 and as of the end of fiscal 2011, short-term investments consisted of municipal bonds of $14.5 million and $16.5 million, respectively. Refer to “NOTE 8 – Fair Value Measurements” for further discussion on how we determined the fair value of our short-term investments. The associated unrealized net losses in both the first quarter of fiscal 2012 and in the full year of fiscal 2011, respectively, were immaterial and have been recorded in the consolidated statements of comprehensive income (loss). As of the end of the first quarter of fiscal 2012, our long-term investments were comprised of auction rate securities and highly-rated interest-bearing municipal bonds that have maturities that are more than one year and are accounted for as available for sale. As of the end of the first quarter of fiscal 2012, the fair value of our long-term municipal bonds was $1.3 million and the associated unrealized losses were immaterial and recorded in the consolidated statements of comprehensive income (loss). As of the end of fiscal 2011, our long-term investments comprised of auction rate securities. Our auction rate securities are AAA/A3-rated debt instruments with maturities of 25 years. They are accounted for as available for sale and backed by pools of student loans guaranteed by the U.S. Department of Education. Their interest rates are reset through an auction process, most commonly at intervals of approximately 4 weeks. This same auction process is designed to provide a means by which these securities can be sold and prior to 2008 had provided a liquid market for them. There continues to be uncertainty in the global credit and capital markets, which has resulted in the failure of auctions representing the auction rate securities we hold as the amount of securities submitted for sale in those auctions exceed the amount of bids. While we have continued to earn and receive interest on our auction rate securities through the date of this report, we concluded that their estimated fair value no longer approximates par value. Due to the lack of availability of observable market quotes on our auction rate securities, the fair market value of these securities has been based on a valuation model using current assumptions. Refer to “NOTE 8 – Fair Value Measurements” for further discussion on how we determined the fair value of our investment in auction rate securities. As of the end of the first quarter of fiscal 2012 and as of the end of fiscal 2011, the fair value of our auction rate securities remained the same at $1.7 million. The fair value of our remaining auction rate securities as of the end of the first quarter of fiscal 2012 reflects a cumulative decline of $0.4 million from the par value. This cumulative $0.4 million decline ($0.2 million net of tax) is deemed temporary as we have the ability to hold these securities and we do not have the intent to sell them below par value. Furthermore, it is not likely that we will be required to sell the securities before the recovery of their amortized cost basis. If uncertainties in the credit and capital markets continue, we may incur additional losses, some of which may be other-than-temporary, which could negatively affect our financial condition or results of operations. In addition, in the event that we decide to sell these securities and it becomes likely that we will be required to sell the securities before the recovery of their amortized cost basis, we may be required to recognize impairment charges against income. We have classified all auction rate securities as non-current assets on our consolidated balance sheet, as we do not expect them to successfully auction and recover their full or par value within the next 12 months. As of the end of the first quarter of fiscal 2012 and 2011, we recorded immaterial unrealized gains and losses, respectively, for our auction rate securities in the consolidated statements of comprehensive income (loss).
