3. Cash, Cash Equivalents and Investments

The Company’s cash equivalents and short-term investments as of June 30, 2012 consisted of corporate bonds, money market funds, municipal bonds, U.S. Treasury bills, U.S. government bonds, asset-backed securities, variable-rate demand notes, international government bonds and U.S. government agency discount notes. The Company’s long-term investments consist of auction-rate securities. Early in fiscal 2008, auctions for many of the Company’s auction-rate securities failed because sell orders exceeded buy orders. As of June 30, 2012, the Company held $12.5 million par value auction-rate securities, all of which have experienced failed auctions. The underlying assets of the securities consisted of student loans and municipal bonds, of which $10.5 million were guaranteed by the U.S. government and the remaining $2.0 million were privately insured. As of June 30, 2012, $4.5 million of the auction-rate securities had credit ratings of AAA, $6.0 million of the auction-rate securities had credit ratings of AA and $2.0 million had a credit rating of A. These securities have contractual maturity dates ranging from 2033 to 2046 and with current yields of 0.26% to 0.57% per year at June 30, 2012. The Company is receiving the underlying cash flows on all of its auction-rate securities. The principal amounts associated with failed auctions are not expected to be accessible until a successful auction occurs, the issuer redeems the securities, a buyer is found outside of the auction process or the underlying securities mature. The Company is unable to predict if these funds will become available before their maturity dates.

The Company does not expect to need access to the capital represented by any of its auction-rate securities prior to their maturities. The Company does not intend to sell, and believes it is not more likely than not that it will be required to sell, its auction-rate securities before their anticipated recovery in market value or final settlement at the underlying par value. The Company believes that the credit ratings and credit support of the security issuers indicate that they have the ability to settle the securities at par value. As such, the Company has determined that no other-than-temporary impairment losses existed as of June 30, 2012.

The Company’s cash, cash equivalents and investments consist of the following (in thousands):

The gross unrealized losses as of June 30, 2012 and December 31, 2011 were due primarily to the illiquidity of the Company’s auction-rate securities and, to a lesser extent, to changes in market interest rates.
