Marketable securities—The estimated fair values of our marketable securities are determined on an individual asset basis based upon quoted prices of identical assets available in active markets (Level 1), quoted prices of identical assets in inactive markets, or quoted prices for similar assets in active and inactive markets (Level 2), and represent the amounts we would expect to receive if we sold these marketable securities.

Restricted cash and investments—The estimated fair values of our restricted cash and investments are based upon quoted prices available in active markets (Level 1), or quoted prices for similar assets in active and inactive markets (Level 2), and represent the amounts we would expect to receive if we sold our restricted cash and investments.

The fair value of our long-term debt or other long-term obligations is estimated based on the quoted market price of the underlying debt issue (Level 1) or, when a quoted market price is not available, the discounted cash flow of future payments utilizing current rates available to us for debt of similar remaining maturities (Level 3). Debt obligations with a short remaining maturity have a carrying amount that approximates fair value.
