Investment Accounting Policy
Cash and Cash Equivalents and Short-Term Investments
Short-term, highly liquid investments with maturities of three months or less when purchased are classified as cash and cash equivalents. Investments with maturities of greater than three months, but not in excess of one year, when purchased are classified as short-term investments. Investments with maturities beyond one year when purchased may be classified as short-term investments if they are expected to be available to support Delta’s short-term liquidity needs. All short-term investments are classified as either available-for-sale or held-to-maturity, and realized gains and losses are recorded using the specific identification method.
