| Fair Value Measurement |
Fair value measurements are based on a three-tier hierarchy that prioritizes the inputs used to measure fair value. These tiers include: Level 1, defined as observable inputs such as quoted market prices in active markets; Level 2, defined as inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly; and Level 3, defined as unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own assumptions.
The fair value of cash and cash equivalents of $24.3 million and $27.6 million as of September 30, 2023, and December 31, 2022, respectively, is derived using Level 1 inputs. The cash equivalents are comprised of short-term bank deposits, money market funds, and U.S. Government debt securities with original maturities of three months or less, and the carrying value is a reasonable estimate of fair value.
The Company had $9.9 million of short-term investments on December 31, 2022, consisting of twelve-month U.S. Government debt securities, which were classified as held to maturity and carried at amortized cost, adjusted for the accretion of discounts using the effective interest method. The carrying value of the debt securities approximates fair value based on Level 1 inputs. The Company held the investments to maturity, which occurred in the second quarter of 2023.
