Our money market funds, treasury bills and U.S. government securities, and agency bonds are classified within Level 1 of the fair value hierarchy because they are valued based on quoted market prices in active markets. We classify commercial paper, corporate bonds, and municipal bonds as Level 2 because they are valued using inputs other than quoted prices which are directly or indirectly observable in the market, including readily-available pricing sources for the identical underlying security which may not be actively traded. None of our financial instruments were classified in the Level 3 category as of October 31, 2023 or January 31, 2023.
