The fair values of the Company’s cash and cash equivalents, and restricted cash approximates the carrying values of these assets at December 31, 2015 and 2014. Restricted cash consists of money market funds, commercial paper and time deposits used for payments on the Company’s non-recourse debt and asset replacement funds contractually required to be maintained at the Company's Australian subsidiary. The fair value of the money market funds is based on quoted market prices (level 1) and the fair value of commercial paper and time deposits is based on market prices for similar instruments (level 2). The fair values of the Company’s 6.625% senior unsecured notes due 2021 (the “6.625% Senior Notes”), 5.125% Senior Notes due 2023 (the “5.125% Senior Notes”), 57/8% Senior Notes due 2022 (the "5.874% Senior Notes due 2022”) and the 5.875% Senior Notes due 2024 (the "5.875% Senior Notes"), although not actively traded, are based on published financial data for these instruments. The fair value of the Company’s non-recourse debt related to Washington Economic Development Finance Authority (“WEDFA”) is based on market prices for similar instruments. The fair value of the non-recourse debt related to the Company’s Australian subsidiary is estimated using a discounted cash flow model based on current Australian borrowing rates for similar instruments. The fair value of borrowings under the Senior Credit Facility is based on an estimate of trading value considering the Company’s borrowing rate, the undrawn spread and similar instruments.
