In order to increase consistency and comparability in fair value measurements, the FASB has established a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels, which are described below: </div> <div align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities.
