Fair Value Measurements

Apart from the equity investments described in Note 7, the Company did not measure any of its assets or liabilities at fair value on a recurring or nonrecurring basis as of September 30, 2021 and 2020.

The carrying values of cash and cash equivalents, restricted cash, accounts receivable, and accounts payable included on the consolidated balance sheets approximated fair value at September 30, 2021 and 2020 because of the immediate or short-term maturity of these financial instruments.

The Company's debt agreements are not traded on an active market. The Company has determined the estimated fair value of its debt to be Level 3, as certain inputs used to determine the fair value of these agreements are unobservable and, therefore, could be sensitive to changes in inputs. The Company utilizes the discounted cash flow method to estimate the fair value of Level 3 debt.

The carrying value and estimated fair value of the Company's long-term debt, including current maturities, were as follows (in millions):
