The fair values of the Company’s cash and cash equivalents, and restricted cash approximates the carrying values of these assets at March 31, 2019 and December 31, 2018. Restricted cash consists of money market funds, bank deposits, commercial paper and time deposits used for asset replacement funds and other funds contractually required to be maintained at the Company's Australian subsidiary. The fair value of the money market funds and bank deposits 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 5.875% senior unsecured notes due 2022 ("5.875% Senior Notes due 2022"), 5.875% senior unsecured notes due 2024 ("5.875% Senior Notes due 2024"), 6.00% senior unsecured notes due 2026 (“6.00% Senior Notes”), and the 5.125% senior unsecured notes due 2023 ("5.125% Senior Notes"), although not actively traded, are based on published financial data for these instruments. The fair values of the Company's non-recourse debt related to the Washington Economic Development Finance Authority ("WEDFA") and the Company’s Australian subsidiary are estimated based on market prices of 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.
