Fair Value Measurement Fair Value Measurement
The Company's financial instruments consist primarily of cash and cash equivalents, investments, accounts receivable, accounts payable and accrued liabilities. The carrying value of accounts receivable, accounts payable and accrued liabilities approximate their fair values because of their short-term nature. Estimated fair values of held to maturity and available-for-sale debt securities are generally based on prices obtained from commercial pricing services.
In connection with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of observable inputs (market data obtained from sources independent from the Company) and to minimize the use of unobservable inputs (the Company’s assumptions about how market participants would price assets and liabilities). As a basis for considering such assumptions, a three-tier fair value hierarchy has been established, which prioritizes the inputs used in measuring fair value as follows:

Level 1 - Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities.
Level 2 - Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. 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 reporting entity’s own assumptions.

The Company's Level 1 instruments include deposits held with banks and short-term investments that are valued using quoted market prices. Level 2 instruments include the Company's short and long-term investments that are valued through third-party pricing services that use verifiable observable market data. The Company had no Level 3 instruments as of December 31, 2021 and December 31, 2020.
