5. Fair Value Measurements

 

The Company records its financial assets and liabilities at fair value. The carrying amounts of certain financial instruments of the Company, including cash and cash equivalents, prepaid expenses and other current assets, accounts payable and accrued liabilities, approximate fair value due to their relatively short maturities. The accounting guidance for fair value provides a framework for measuring fair value, clarifies the definition of fair value, and expands disclosures regarding fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The accounting guidance establishes a three-tiered hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value as follows:

 

 

Level I: Inputs which include quoted prices in active markets for identical assets and liabilities;

 

 

Level II: Inputs other than Level I that are observable, either directly or indirectly, such as quoted prices 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; and

 

 

Level III: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

 

The fair value of the Company’s financial assets includes money market funds, overnight reverse repurchase agreements and a deposit for the lease of the Company's South San Francisco facility. Money market funds, included in cash and cash equivalents in the accompanying condensed consolidated balance sheets, were $343.4 million and $57.6 million as of September 30, 2020 and December 31, 2019, respectively, and are Level I assets as described above. Overnight reverse repurchase agreements, included in cash and cash equivalents in the accompanying condensed consolidated balance sheets, were zero and $100.0 million as of September 30, 2020 and December 31, 2019, respectively, and are Level II assets as described above. There were no unrealized gains or losses from overnight reverse repurchase agreements at September 30, 2020 and December 31, 2019. The deposit for the lease, included in restricted cash in the accompanying condensed consolidated balance sheets, was $603,000 as of September 30, 2020 and December 31, 2019, and is a Level I asset as described above.

 

The fair value of the contingent consideration in Note 4, Business Combination, associated with the agreement with NanoString on December 3, 2019, includes inputs that are not observable in the market and thus represent a Level III financial liability. The estimation of the fair value of the contingent consideration is based on the present value of the expected payments calculated by assessing the likelihood of when the related milestones would be achieved, discounted using the Company's estimated borrowing rate. These estimates form the basis for making judgments about the carrying value of the contingent consideration that are not readily apparent from other sources. Changes to the forecasts for the achievement of the milestones and the estimates of the borrowing rate can significantly affect the estimated fair value of the contingent consideration.  As of September 30, 2020, the achievement of the milestones is not forecasted to occur within the next 12 months.  As a result, the contingent consideration is included in long term liabilities in the condensed consolidated balance sheets. As of September 30, 2020, the Company calculated the estimated fair value of the milestones using the following significant unobservable inputs:
