Fair Value Disclosures [Abstract]

Fair Value Measurements on a Recurring Basis

The following tables present assets and liabilities measured at fair value on a recurring basis as of year-end 2021 and 2020 in the consolidated balance sheet by fair value hierarchy level, as described below. 

Level 1 measurements consist of unadjusted quoted prices in active markets for identical assets or liabilities.  Level 2 measurements include quoted prices in markets that are not active or model inputs that are observable either directly or indirectly for substantially the full term of the asset or liability. Level 3 measurements include significant unobservable inputs.
