[1] | Cash equivalents and restricted cash equivalents consist of money market funds, deposits, and investments with original maturities of three months or less.
[2] | Marketable securities include CDs, VRDNs, and commercial paper, which are classified as available-for-sale. At June 27, 2014 and December 27, 2013, we had $4.5 million and $6.0 million of CDs with maturities greater than one year, which are classified as Other assets on our Consolidated Balance Sheets. VRDNs with contractual maturities beyond one year are classified as short-term based on their highly liquid nature and because they represent the investment of cash that is available for current operations. Despite the long-term nature of their stated contractual maturities, we routinely buy and sell these securities and believe we have the ability to quickly sell them to the re-marketing agent at par value plus accrued interest in the event we decide to liquidate our investment in a particular VRDN.
[3] | Other restricted assets primarily consists of deferred compensation plan accounts, which are comprised of mutual funds.
