Accounting standards define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value. An asset’s or liability’s level is based on the lowest level of input that is significant to the fair value measurement. Assets and liabilities carried at fair value are valued and disclosed in one of the following three levels of the valuation hierarchy:

Level 1: Quoted market prices in active markets for identical assets or liabilities.

Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data.

Level 3: Unobservable inputs reflecting the reporting entity’s own assumptions.

At March 31, 2021 and 2020, the carrying value of cash and cash equivalents, accounts receivable, prepaid expense and other current assets, accounts payable and other current liabilities approximate fair value due to the short-term nature of such instruments.

The carrying value of the Company's debt approximates fair value based on current market rates (Level 2).

Nonrecurring fair value measurements

The Company uses fair value measures when determining assets and liabilities acquired in an acquisition as described above in the Notes To Condensed Consolidated Financial Statements, which are considered a Level 3 measurement.
