[3] Short-term investments primarily consist of corporate debt securities and are classified as available-for-sale securities recognized at amortized cost which is the same as fair value at December 30, 2011. These securities are valued using quoted prices in active markets for identical assets. If quoted prices in active markets for identical assets are not available, we use quoted prices for similar assets that are observable either directly or indirectly.
