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 2023 and 2022 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. There were no transfers between Level 1, Level 2 and Level 3 assets or liabilities in 2023 or 2022.
