Restricted Cash Equivalents Our restricted cash equivalents include money market mutual funds and commercial paper. The carrying value of cash equivalents approximate their fair values due to the short-term maturities and are classified as Level 1 in the fair value hierarchy because we use quoted market prices that are readily available in an active market to determine the fair value. Restricted Investments Our restricted investments include U.S. Treasuries, an exchange traded fund and a certificate of deposit. The U.S. Treasuries and exchange traded fund are classified as Level 1 securities in the fair value hierarchy as we use active quoted market prices that are readily available in an active market to determine fair value. The certificate of deposit is classified as Level 2 in the fair value hierarchy as we use a market approach that compares the fair values on certificates with similar maturities. We did not have any Level 3 financial instruments as of March 31, 2018 and December 31, 2017. There were no transfers between levels as of March 31, 2018 and December 31, 2017. Fair Value of Financial Instruments Disclosures Notes Payable The carrying value of our notes payable at March 31, 2018 and December 31, 2017 was $415 million and $425 million, respectively. The estimated fair values of our notes payable at March 31, 2018 and December 31, 2017 were $418 million and $428 million, respectively. These valuations are considered Level 2 in the hierarchy for fair value measurement and are based on quoted market prices.
