6. Fair Value Measurements

The Company records its financial assets and liabilities at fair value. The carrying amounts of certain of the Company’s financial instruments, including cash, trade receivables, net and accounts payable, approximate their fair value due to their short maturities. Fair value is defined as the exchange price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The accounting guidance for fair value establishes a framework for measuring fair value and a fair value hierarchy that prioritizes the inputs used in valuation techniques. The accounting standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value which are the following:

Level 1 – Observable inputs, such as unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2 – Observable inputs, either directly or indirectly, other than quoted prices in active markets for identical assets or liabilities, such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities; therefore, requiring an entity to develop its own valuation techniques and assumptions.

The following tables set forth the Company’s fair value hierarchy for its financial assets and liabilities measured at fair value on a recurring basis as follows (in thousands):

Equity Securities

The equity securities consisted of an investment in Rezolute’s common stock and are classified on the condensed consolidated balance sheets as current assets as of March 31, 2023 and December 31, 2022. The equity securities are revalued each reporting period with changes in fair value recorded in the other income (expense), net line item of the condensed consolidated statements of operations and comprehensive loss. As of March 31, 2023 and December 31, 2022, the Company valued the equity securities using the closing price for Rezolute’s common stock traded on the Nasdaq Stock Market of $1.92 and $2.07, respectively. The inputs that were used to calculate the fair value of the equity securities were observable prices in active markets and therefore were classified as a Level 1 fair value measurement.

Contingent Consideration

The estimated fair value of the Bioasis Contingent Consideration liability at the inception of the Bioasis RPA represents the future consideration that is contingent upon the achievement of specified development milestones for a product candidate. The fair value measurement is based on significant Level 3 inputs such as anticipated timelines and probability of achieving development milestones of each licensed product candidate.

Changes in the fair value of the liability for contingent consideration will be recorded in the other income (expense), net line item of the condensed consolidated statements of operations and comprehensive loss until settlement. During the three months ended March 31, 2023, there were no changes in the estimated fair value of the contingent consideration recorded pursuant to the Bioasis RPA from the initial value of $0.1 million.
