Cash equivalents and restricted cash equivalents and investments. Cash equivalents generally consist of money market funds. Restricted cash equivalents and investments primarily support letters of credit that relate to certain projected self-insurance obligations and airport commitments and generally consist of money market funds and time deposits. These investments are recorded at cost, which approximates fair value. Fair value is based on a market approach using prices and other relevant information generated by market transactions involving identical or comparable assets.

Short-term investments. Short-term investments generally consist of U.S. Treasury securities, U.S. government agency securities, asset and mortgage-backed securities, corporate obligations and other fixed income securities. The Treasury securities designated as held-to-maturity are recorded at cost, which approximates fair value, while those that are designated as available-for-sale are valued based on quoted market prices. The fair values of our U.S. government agency securities, asset- and mortgage-backed securities, corporate obligations, and other fixed term securities are based on a market approach using industry standard valuation techniques that incorporate observable inputs such as quoted interest rates, benchmark curves, credit ratings of the security and other observable information.

Long-term investments. Our long-term investments that are measured at fair value primarily consist of equity investments in Grupo Aeroméxico, S.A.B. de C.V., the parent company of Aeroméxico, and GOL Linhas Aéreas Inteligentes, S.A, the parent company of GOL. Shares of the parent companies of Aeroméxico and GOL are traded on public exchanges and we have valued our investments based on quoted market prices. The investments are classified in other noncurrent assets.

Hedge derivatives. Our derivative contracts are generally negotiated with counterparties without going through a public exchange. Accordingly, our fair value assessments give consideration to the risk of counterparty default (as well as our own credit risk).

Fuel contracts. Our fuel hedge portfolio consists of call options, put options, swaps and futures. The products underlying the hedge contracts include crude oil, diesel fuel and jet fuel as these commodities are highly correlated with the price of jet fuel that we consume. Option contracts are valued under an income approach using option pricing models based on data either readily observable in public markets, derived from public markets or provided by counterparties who regularly trade in public markets. Volatilities used in these valuations ranged from 11% to 24% depending on the maturity dates, underlying commodities and strike prices of the option contracts. Swap contracts are valued under an income approach using a discounted cash flow model based on data either readily observable or derived from public markets. Discount rates used in these valuations vary with the maturity dates of the respective contracts and are based on LIBOR. Futures contracts and options on futures contracts are traded on a public exchange and valued based on quoted market prices.

Interest rate contracts. Our interest rate derivatives consist of swap contracts and are valued primarily based on data readily observable in public markets.

Foreign currency exchange contracts. Our foreign currency derivatives consist of Japanese yen and Canadian dollar forward contracts and are valued based on data readily observable in public markets.
