Fair Value Measurements

FAIR VALUE MEASUREMENTS

Our financial instruments include cash and cash equivalents, short-term investments, accounts receivable, customer deposits, accounts payable and accrued liabilities. The carrying amounts of such financial instruments approximate their fair value due to the short-term nature of these instruments.

Liabilities measured at fair value on a recurring basis are categorized in the tables below based upon the lowest level of significant input to the valuations:

	As of March 31, 2021
	Level 1		Level 2		Level 3
Liabilities:
Contingent consideration (1)	$	—	$	—	$	976
Total	$	—	$	—	$	976
	As of December 31, 2020
	Level 1		Level 2		Level 3
Liabilities:
Contingent consideration (1)	$	—	$	—	$	1,056
Total	$	—	$	—	$	1,056

(1)Contingent consideration liability represents arrangements to pay the former owners of certain companies we acquired based on the attainment of future product release milestones and is reported in current accrued liabilities. We use a probability-weighted discounted cash flow model to estimate the fair value of contingent consideration liabilities. These probability weightings are developed internally and assessed on a quarterly basis. The remaining undiscounted maximum payment under these arrangements was $1.2 million as of March 31, 2021.
