[1] The fair values of impaired assets were generally estimated based on the present values of the associated cash flows and market values with respect to land. The impaired assets consist of land and buildings, are classified as held-for-sale and included in “Prepaid expenses and other current assets.”

[2] The carrying value of the aircraft, which reflects current market conditions, approximated its fair value.
