Fair Value of Financial Instruments Fair Value of Financial Instruments
Our financial instruments consist of cash and cash equivalents, restricted cash, accounts receivable, accounts payable, note receivable-affiliate and long-term debt (excluding finance leases and other obligations) and certain indemnification obligations. Due to their short-term nature, the carrying amounts of our cash and cash equivalents, restricted cash, accounts receivable, note receivable-affiliate and accounts payable approximate their fair values.

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between independent and knowledgeable parties who are willing and able to transact for an asset or liability at the measurement date. We use valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs when determining fair value and then we rank the estimated values based on the reliability of the inputs used following the fair value hierarchy.

We determined the fair values of our long-term debt, including the current portion, based primarily on inputs other than quoted market prices in active markets that are either directly or indirectly observable such as discounted future cash flows using current market interest rates.

The three input levels in the hierarchy of fair value measurements are defined by the FASB are generally as follows:
Input LevelDescription of Input
Level 1Observable inputs such as quoted market prices in active markets.
Level 2Inputs other than quoted prices in active markets that are either directly or indirectly observable.
Level 3Unobservable inputs in which little or no market data exists.
The following table presents the carrying amounts and estimated fair values of our financial liabilities as of September 30, 2022 and December 31, 2021, as well as the input level used to determine the fair values indicated below:
