[1] | Amounts due after one year include CDs with maturities between one and two years and are recorded in Other assets on the Consolidated Balance Sheets.
[2] | Cash equivalents and restricted cash equivalents consist of money market funds, deposits, and investments with original maturities of three months or less.
[3] | Marketable securities include CDs, VRDNs, and commercial paper, which are classified as available-for-sale. Our CDs include $6.0 million with maturities greater than one year and 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.
[4] | Primarily consists of restricted cash in money market accounts and deferred compensation plan accounts, which are comprised of mutual funds.
[5] | Restricted investments classified as held-to-maturity consist of highly rated investment grade securities, primarily in municipal-debt securities, corporate-debt securities, asset-backed securities, and U.S. agency debentures.
