NOTE

8:

FAIR VALUE OF FINANCIAL INSTRUMENTS

Pursuant to the accounting guidance for fair value measurement and its subsequent updates, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., the “exit price”) in an orderly transaction between market participants at the measurement date. The accounting guidance establishes a hierarchy for inputs used in measuring fair value that minimizes the use of unobservable inputs by requiring the use of observable market data when available. Observable inputs are inputs that market participants would use in pricing the asset or liability based on active market data. Unobservable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability based on the best information available in the circumstances.

The fair value hierarchy is broken down into the

three

input levels summarized below:

●

Level

1

—Valuations are based on quoted prices in active markets for identical assets or liabilities and readily accessible by us at the reporting date. Examples of assets and liabilities utilizing Level

1

inputs are certain money market funds, U.S. Treasuries and trading securities with quoted prices on active markets.

●

Level

2

—Valuations based on inputs other than the quoted prices in active markets that are observable either directly or indirectly in active markets. Examples of assets and liabilities utilizing Level

2

inputs are U.S. government agency bonds, corporate bonds, commercial paper, certificates of deposit and over-the- counter derivatives.

●

Level

3

—Valuations based on unobservable inputs in which there are little or

no

market data, which require the Company to develop its own assumptions.

Warrants issued in the

overallotment closing, which are discussed further in Note

9,

contained provisions that

may 

require the Company to settle the warrants in cash in an event outside the Company's control and are therefore accounted for as liabilities, with changes in the fair values included in net loss for the respective periods. Because some of the inputs to the valuation model were either

not

observable or were

not

derived principally from or corroborated by observable market data by correlation or other means, the warrant liability was classified as Level

3

in the fair value hierarchy as of

December 31, 2020.
