KLA-Tencor的投资组合包含的corporate and government securities that have a maximum maturity of three years. The longer the duration of these securities, the more susceptible they are to changes in market interest rates and bond yields. As yields increase, those securities with a lower yield-at-cost show a mark-to-market unrealized loss. All unrealized losses are due to changes in interest rates and bond yields. The Company has the ability to realize the full value of all of these investments upon maturity. The following table summarizes the fair value and gross unrealized losses of the Company's investments that were in an unrealized loss position as of June 30, 2011 :

Actual maturities may differ from contractual maturities, because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Net realized gains for the fiscal years ended June 30, 2011 and June 30, 2010 were $2.5 million and $4.0 million , respectively. Net realized losses for the fiscal year ended June 30, 2009 were $0.6 million .
During the fiscal years ended June 30, 2008, 2009 and 2010, the Company’s investment portfolio included auction rate securities, which were investments with contractual maturities generally between 20 to 30 years. They are usually found in the form of municipal securities, preferred stock, a pool of student loans, or collateralized debt obligations whose interest rates are reset. The reset typically occurs every seven to forty-nine days , through an auction process. At the end of each reset period, investors can sell or continue to hold the securities at par. The auction rate securities that were held by the Company were backed by student loans and were collateralized, insured and guaranteed by the United States Federal Department of Education. In addition, all auction rate securities that were held by the Company were rated by the major independent rating agencies as either AAA or Aaa. In February 2008, because sell orders exceeded buy orders, auctions failed for approximately $48.2 million in par value of municipal auction rate securities that were then held by the Company. These failures were not believed to be a credit issue, but rather caused by a lack of liquidity. The funds associated with these failed auctions might not have been accessible until the issuer called the security, a successful auction occurred, a buyer was found outside of the auction process, or the security matured. By letter dated August 8, 2008, the Company received notification from UBS AG (“UBS”), in connection with a settlement entered into between UBS and certain regulatory agencies, offering to repurchase all of the Company’s auction rate security holdings at par value. The Company formally accepted the settlement offer and entered into a repurchase agreement (“Agreement”) with UBS on November 11, 2008 (“Acceptance Date”). By accepting the Agreement, the Company (1) received the right (“Put Option”) to sell its auction rate securities at par value to UBS between June 30, 2010 and June 30, 2012 and (2) gave UBS the right to purchase the auction rate securities from the Company any time after the Acceptance Date as long as the Company received the par value. The Company accounted for the Put Option as a freestanding financial instrument, and during the three months ended December 31, 2008, it made an election to transfer these auction rate securities from available for sale to trading securities. During the fiscal year ended June 30, 2010, $23.9 million of the auction rate securities were called at par by the issuers. The Put Option was exercised on June 30, 2010 to sell all $16.8 million of the Company's remaining auction rate securities at par value and was subsequently settled in
