4. Fair Value Measurements

The Company held U.S. treasury bills of $20.1 million and certificates of deposit of $7.5 million at June 30, 2020. The Company held U.S. treasury bills of $27.5 million at December 31, 2019. Unrealized losses and the associated tax impact on the Company’s available-for-sale securities were insignificant as of June 30, 2020 and December 31, 2019, respectively.

The Company’s investments are all classified within Levels 1 and 2 of the fair value hierarchy. The Company’s investments classified within Level 1 of the fair value hierarchy are valued based on quoted prices in active markets. Level 2 investments are based on matrix pricing compiled by third party pricing vendors, using observable market inputs such as interest rates, yield curves, and credit risk. For cash, current receivables, accounts payable, long-term debt and interest accrual, the carrying amounts approximate fair value, because of the short maturity of these instruments, and therefore fair value information is not included in the table below. Contingent consideration related to the previously described business combinations are classified within Level 3 of the fair value hierarchy as the determination of fair value uses considerable judgement and represents the Company’s best estimate of an amount that could be realized in a market exchange for the asset or liability.

The fair value hierarchy of the Company's cash equivalents, investments and liabilities at fair value was as follows:

Contingent Consideration

The following table provides a rollforward of the contingent consideration related to business acquisitions discussed in Note 3.

Under the Parcus Medical and Arthrosurface merger agreements, there are earn-out milestones totaling $100 million payable from 2020 to 2022. Parcus Medical and Arthrosurface each have net sales earn-out milestones annually from 2020 to 2022, while Arthrosurface has regulatory earn-out milestones in 2020 and 2021. Projected contingent payment amounts are discounted back to the current period using a discounted cash flow model or a Monte Carlo simulation approach. The unobservable inputs used in the fair value measurement of the Company’s contingent consideration are the probabilities of successful achievement, the weighted average cost of capital used for the Monte Carlo simulation, discount rate and the periods in which the milestones are expected to be achieved. The discount rates used for the net sales and regulatory earn-out milestones ranged from 3.3% - 3.8%. The probability of successful achievement of the regulatory earn-out milestones range from 60%-90% for Arthrosurface, which remained unchanged from the acquisition date to June 30, 2020. The key variables that led to a decrease in contingent consideration versus the acquisition date are the decrease in near term revenues due to the COVID-19 pandemic and an increase in the weighted average cost of capital from 11.5% to 14.0% for Arthrosurface and 14.5% to 16.0% for Parcus Medical. Increases or decreases in any of the probabilities of success in which milestones are expected to be achieved would result in a higher or lower fair value measurement, respectively. Increases or decreases in the discount rate would result in a lower or higher fair value measurement, respectively.

The fair value of contingent consideration is assessed on a quarterly basis. The $4.2 million increase in fair value of the contingent consideration for the three-month period ended June 30, 2020 was primarily due to an increase in revenue assumptions based on second quarter results and future projections, and other assumption changes as a result of events that occurred in the quarter. The $20.3 million decrease in fair value of the contingent consideration for six-month period ended June 30, 2020 was due to a decrease in the near term projections of revenue due to the COVID-19 pandemic.
