SHORT-TERM INVESTMENTS

We have short-term investments, with original maturities of longer than 3 months, in U.S. Treasury securities and commercial paper as of September 23, 2012, and in U.S. Treasury securities as of December 25, 2011. Since we have the intention and ability to hold these investments to maturity, they are classified as held-to-maturity and are reported at amortized cost.

The carrying value of the short-term investments was $279.7 million as of September 23, 2012, which included approximately $250 million in U.S. Treasury securities and approximately $30 million in commercial paper, and $104.8 million in U.S. Treasury securities as of December 25, 2011. The short-term investments have remaining maturities of about 1 month to 10 months as of September 23, 2012.

See Note 8 for information regarding the fair value of our short-term investments.
