Fair Value Measurements |
3. Fair Value Measurements The following table sets forth the fair value of the Company’s financial assets measured on a recurring basis by level within the fair value hierarchy:
Where applicable, the Company uses quoted market prices in active markets for identical assets to determine fair value. This pricing methodology applies to Level 1 investments, which are comprised of money market funds, U.S. government securities and the shares of Vaxcyte common stock held by the Company. If quoted prices in active markets for identical assets are not available, then the Company uses quoted prices for similar assets or inputs other than quoted prices that are observable, either directly or indirectly. These investments are included in Level 2 and consist of commercial paper, corporate debt securities, asset-backed securities, U.S. agency securities and supranational debt securities. These assets are valued using market prices when available, adjusting for accretion of the purchase price to face value at maturity. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires management to make judgments and consider factors specific to the asset or liability. In certain cases where there is limited activity or less transparency around inputs to valuation, securities are classified as Level 3 within the valuation hierarchy. As of June 30, 2023, the deferred royalty obligation related to the sale of future Vaxcyte royalties was classified as Level 3 within the valuation hierarchy. As of December 31, 2022, the Company did not hold any securities that were classified as Level 3 within the valuation hierarchy. Investments in Equity Securities As of June 30, 2023 and December 31, 2022, the Company held 667,780 shares of Vaxcyte common stock with an estimated fair value of $33.3 million and $32.0 million, respectively. The Company recognized an unrealized gain of $8.3 million and an unrealized loss of ($3.7) million for the three months ended June 30, 2023 and 2022, respectively, and an unrealized gain of $1.3 million and an unrealized loss of ($3.2) million for the six months ended June 30, 2023 and 2022, respectively. |
