SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract] |
Available-for-Sale Debt Securities | Available-for-sale debt investments are reported at fair value, with unrealized gains or losses (net of tax) reported in Accumulated other comprehensive (loss) income. The fair values of our available-for-sale securities are Level 1 measurements, based on quoted prices from active markets for identical assets. In the event of a sale of an available-for-sale debt investment, we would determine the cost of the investment sold at the specific individual security level, and would include any gain or loss in Interest income and other income, net, where we also report periodic interest earned and the amortization (accretion) of discounts (premiums) related to these investments. The table below provides information on our available-for-sale debt securities.
