Fair Value Disclosures [Text Block] | 10. FAIR VALUE MEASUREMENTS Fair Value Hierarchy The Company has estimated the fair value of its financial assets by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:
● | Level 1—includes instruments with quoted prices in active markets for identical assets.
● | Level 2—includes instruments for which the valuations are based upon quoted market prices in active markets involving similar assets or inputs other than quoted prices that are observable for the assets. The market inputs used to value these instruments generally consist of market yields, recently executed transactions, broker/dealer quotes or alternative pricing sources with reasonable levels of price transparency. Pricing sources may include industry standard data providers, security master files from large financial institutions, and other third-party sources used to determine a daily market value.
● | Level 3—includes instruments for which the valuations are based on inputs that are unobservable and significant to the overall fair value measurement.
Financial Assets Measured at Fair Value on a Recurring Basis The following tables detail the fair value of the Company’s financial assets measured on a recurring basis (in thousands):
