FAIR VALUE MEASUREMENTS

6 Months Ended

Jun. 30, 2020

The three levels of the fair value hierarchy established are as follows:

Level 1 Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2 Pricing inputs other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.

Level 3 Unobservable inputs that reflect the Company’s assumptions about the assumptions that market participants would use in pricing the asset or liability. Unobservable inputs shall be used to measure fair value to the extent that observable inputs are not available.

The following table presents the Company’s fair value measurements as of June 30, 2020 along with the level within the fair value hierarchy in which the fair value measurements in their entirety fall.

The following table presents the Company’s fair value measurements as of December 31, 2019 along with the level within the fair value hierarchy in which the fair value measurements in their entirety fall.

There have been no changes in valuation techniques or transfers between fair value measurement levels during the periods ended June 30, 2020 and December 31, 2019. The fair value of Level 2 instruments classified as cash equivalents and marketable debt securities are valued using a third-party pricing agency where the valuation is based on observable inputs including pricing for similar assets and other observable market factors. The Company’s marketable equity security investment in Biocartis is classified as a Level 1 instrument. See Note 7 for additional information on Biocartis.

Contingent Consideration

In connection with the Biomatrica Acquisition, a contingent earn-out liability was created to account for an additional $20.0 million in contingent consideration that could be earned based upon certain revenue milestones being met. The following table provides a roll-forward of the fair values of the contingent consideration, which includes Level 3 measurements:


(In thousands)	Contingent consideration
Balance, January 1, 2020	$	(2,879)
Changes in fair value	—
Gains (losses) recognized in earnings	—
Payments	328
Balance, June 30, 2020	$	(2,551)

As of June 30, 2020, the fair value of the contingent earn-out liability is classified as a component of other long-term liabilities in the Company’s condensed consolidated balance sheet.

This fair value measurement of contingent consideration related to the Biomatrica acquisition was categorized as a Level 3 liability, as the measurement amount is based primarily on significant inputs not observable in the market. The Company evaluates the fair value of expected contingent consideration and the corresponding liability each annual reporting period using the Monte Carlo Method, which is consistent with the initial measurement of the expected Biomatrica Acquisition earn-out liability. The Company estimates projections during the earn-out period utilizing various potential pay-out scenarios. Probabilities were applied to each potential scenario and the resulting values were discounted using a rate that considers weighted average cost of capital as well as a specific risk premium associated with the riskiness of the earn-out itself, the related projections, and the overall business.

Non-Marketable Equity Investment

The Company has non-marketable equity investments which are initially recorded at the estimated fair value based on observable transactions. The Company remeasures the fair value only when an observable transaction occurs during the period that would suggest a change in the carrying value of the investment. As of June 30, 2020 and December 31, 2019, the Company had non-marketable equity investments of $11.8 million, which are classified as a component of other long-term assets in the Company’s condensed consolidated balance sheets. The Company’s preferred stock investment in Epic Sciences represents $10.8 million of the total non-marketable equity investments. There have been no observable transactions during the three and six months ended June 30, 2020 and 2019. See Note 7 for additional information regarding the terms of the investment in Epic Sciences.

Fair Value of Long-Term Debt and Convertible Notes

The Company measures the fair value of its convertible notes and long-term debt for disclosure purposes. The following table summarizes the Company’s outstanding convertible notes and long-term debt:


	June 30, 2020						December 31, 2019
(In thousands)	Carrying Amount (1)		Fair Value		Carrying Amount (1)		Fair Value
2028 Convertible notes (2)	$	786,711	$	1,101,413	$	—	$	—
2027 Convertible notes (2)	498,707		774,328		483,909		843,741
2025 Convertible notes (2)	248,965		419,015		319,696		592,482
Construction loan (3)	24,263		24,263		24,866		24,866

______________

(1)The carrying amounts presented are net of debt discounts and debt issuance costs (see Note 12 and Note 15 of the condensed consolidated financial statements for further information).

(2)The fair values are based on observable market prices for this debt, which is traded in active markets and therefore is classified as a Level 2 fair value measurement. A portion of the 2025 convertible notes were settled in 2020 resulting in a decrease in the liability.

(3)The carrying amount of the construction loan approximates fair value due to the short-term nature of this instrument. The construction loan is privately held with no public market for this debt and therefore is classified as a Level 3 fair value measurement. The change in the fair value was due to payments made on the loan resulting in a decrease in the liability.
