Fair Value Measurements |
Fair Value Measurements | 3. Fair Value Measurements The fair values of financial instruments are classified into one of the following categories:
| ● | Level 1 — Quoted prices in active markets for identical assets or liabilities.
| ● | Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
| ● | Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
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. Where quoted prices are available in an active market, securities are classified as Level 1. Level 1 assets consist of highly liquid money market funds that are included in cash and cash equivalents, and restricted cash. There were no transfers between Level 1, Level 2 and Level 3 during the periods presented. Financial assets and liabilities subject to fair value measurements on a recurring basis and the level of inputs used in such measurements were as follows:
