Fair Value Measurements Fair Value Measurements
The Company's financial instruments consist primarily of cash, cash equivalents, restricted cash, investments, accounts receivable, accounts payable, and accrued liabilities. The carrying value of accounts receivable, accounts payable, and accrued liabilities approximate their fair value because of their short-term nature. Estimated fair value of 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 following table summarizes the financial assets (cash, cash equivalents, restricted cash, and investments) measured at fair value on a recurring basis:

The Company's Level 1 instruments include cash, cash equivalents, and restricted cash that are valued using quoted market prices. Aurinia estimates the fair values of investments in corporate debt securities, government and government related securities and certificates of deposits by taking into consideration valuations obtained from third-party pricing services. The fair value of the Company's investments classified within Level 2 is based upon observable inputs that may include benchmark yield curves, reported trades, issuer spreads, benchmark securities and reference data including market research publications. At September 30, 2024 and December 31, 2023, the weighted average remaining contractual maturities of Aurinia's Level 2 investments were approximately 7 months for both periods. The Company's policy is for these investments to have an overall rating of A-1, or higher, by Standard & Poor's, or an equivalent rating by Moody’s or Fitch.
No credit loss allowance was recorded as of September 30, 2024 and December 31, 2023, as the Company does not believe the unrealized loss is a result of a credit loss due to the nature of the investments. Aurinia also considered the current and expected future economic and market conditions and determined that the estimate of credit losses was not significantly impacted.
Refer to Note 4, Cash, Cash Equivalents, Restricted Cash, and Investments, for the carrying amount and related unrealized gains (losses) by type of investment.
