We classify our highly liquid money market funds and publicly held equity securities within Level 1 of the fair value hierarchy because they are valued based on quoted market prices in active markets. We classify our commercial paper, agency bonds, corporate and other debt securities, U.S. government agency securities, treasury bills, and certificates of deposit within Level 2 because they are valued using inputs other than quoted prices that are directly or indirectly observable in the market, including readily available pricing sources for the identical underlying security, which may not be actively traded. We classify our privately held debt securities as Level 3 due to the lack of relevant observable market data over fair value inputs, such as the probability weighting of the various scenarios that can impact settlement of the arrangement.
