Fair Value Measurements
As of September 30, 2021, the carrying value of cash and cash equivalents, trade accounts receivables, accounts payable, accrued expenses and accrued interest approximates fair value due to the short-term nature of such instruments. The carrying amount of the Notes at September 30, 2021 was $213.5 million compared to the estimated fair value of $213.3 million, based on the prevailing interest rates and trading activity of our Notes.
We have certain assets that are measured at fair value on a
basis that are adjusted to fair value only when the carrying values exceed the fair values. The categorization of the framework used to price the assets is considered Level 3 due to the subjective nature of the unobservable inputs used when estimating the fair value.
The following table summarizes the fair value of our financial assets and liabilities that are measured at fair value:
