FAIR VALUE OF FINANCIAL INSTRUMENTS FAIR VALUE OF FINANCIAL INSTRUMENTS
The Company measures certain financial assets and liabilities at fair value. The accounting standards related to fair value measurements define fair value and provide a consistent framework for measuring fair value under the authoritative literature. A fair value hierarchy was established, which prioritizes the inputs used in measuring fair value into three broad levels.

Level 1 – Quoted prices in active markets for identical assets or liabilities;

Level 2 – Observable market-based inputs or unobservable inputs that are corroborated by market data; and

Level 3 – Significant unobservable inputs that are not corroborated by market data.  Generally, these fair value measures are model-based valuation techniques such as discounted cash flows, and are based on the best information available, including our own data.

The following table summarize the assets and liabilities measured at fair value on a recurring basis as of March 31, 2022 and December 31, 2021.

The Company's level 1 assets consist of cash equivalents which are generally comprised of short-term, liquid investments with original maturity of three months or less at inception and other short term investments which are comprised of exchange traded mutual funds and marketable securities with a maturity date greater than 3 months.

The fair value of the contingent consideration payment is considered a Level 3 fair value measurement and was determined with the assistance of an independent valuation specialist at the original issuance date using an option pricing model and a Monte Carlo simulation based on forecasted annual revenue, expected volatility and discount rates. The fair value of contingent consideration liabilities assumed in business combinations is recorded as part of the purchase price consideration of the acquisition and is determined using a discounted cash flow model or probability simulation model. The significant inputs of such models are not always observable in the market, such as certain financial metric growth rates, volatility rates, projections associated with the applicable milestone, the interest rate, and the related probabilities and payment structure in the contingent consideration arrangement. The adjustments in the fair value of the contingent consideration payments included expense adjustment of $2,570 and $4,150 for the three month periods ended March 31, 2022 and March 31, 2021, respectively, in other expenses on the condensed consolidated statements of operations.

The following table summarizes the change in fair value of Level 3 instruments in 2022:

The recurring Level 3 fair value measurements of contingent consideration liabilities associated with commercial sales milestones include the following significant unobservable inputs as of March 31, 2022 and December 31, 2021:

(1) The present value discount rate includes estimated risk premium.
The estimated fair value reflects assumptions made by management as of March 31, 2022; however, the actual amount ultimately paid could be higher or lower than the fair value of the remaining contingent consideration.
