The Company classifies its U.S. treasury securities and money market funds within Level 1 of the fair value hierarchy, as their fair value is determined by quoted prices in active markets for identical assets. The Company classifies its corporate debt securities within Level 2 of the fair value hierarchy as the fair value of these securities is determined using inputs other than quoted prices that are directly or indirectly observable in the market, including readily available pricing sources for underlying securities that may not be actively traded.
The following table presents the level within the fair value hierarchy at which the Company’s held-to-maturity investments are measured (in thousands):
