12.  Fair Value of Financial Instruments

ASC 820, Fair Value Measurement (ASC 820) defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820 also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

The levels of the fair value hierarchy established by ASC 820 are:

Level 1: inputs are quoted prices, unadjusted, in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Level 2: inputs are other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. A Level 2 input must be observable for substantially the full term of the asset or liability.

Level 3: inputs are unobservable and reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the asset or liability.

As of December 31, 2021 and 2020, we considered the recorded value of certain of our financial assets and liabilities, which consist primarily of cash and cash equivalents, contract receivable and accounts payable, to approximate fair value based upon their short-term nature.

During the years ended December 31, 2021 and 2020, we did not have any transfers into or out of Level 3. The following table presents assets measured at fair value at December 31, 2021:
