Fair Value of Financial Instruments, Policy [Policy Text Block]
Fair value adjustments related to financial instruments where the fair value option has been elected are recorded through earnings for the years ended December 31, 2019 and 2018. Certain unobservable inputs may (in isolation) have either a directionally consistent or opposite impact on the fair value of the financial instrument for a given change in that input. When multiple inputs are used within the valuation techniques for loans, a change in one input in a certain direction may be offset by an opposite change from another input.
