The Company holds an investment in a debt mutual fund for which the Company elected the fair value option. The investment would have otherwise been recorded using the equity method. The debt mutual fund has no single maturity date. At June 26, 2011, the Company had an effective ownership interest in the debt mutual fund of 19.0%. Changes in fair value associated with this investment are recognized in net investment income. The Company believes that recording the investment at fair value and reporting the investment as a marketable security is preferable to applying the equity method because the Company is able to redeem its shares at net asset value, which is determined daily. At September 26, 2010, marketable securities also included $400 million of time deposits that matured in December 2010.
At June 26, 2011, the contractual maturities of available-for-sale debt securities were as follows (in millions):

At June 26, 2011, the Company concluded that the unrealized losses were temporary. Further, for common and preferred stock with unrealized losses, the Company has the ability and the intent to hold such securities until they recover, which is expected to be within a reasonable period of time. For debt securities with unrealized losses, the Company does not have the intent to sell, nor is it more likely than not that the Company will be required to sell, such securities before recovery or maturity.
