Fair Value Disclosures [Abstract]
Fair Value Measurements	For disclosure purposes, we utilize a fair value hierarchy to categorize qualifying assets and liabilities into three broad levels based on the priority of the inputs used to determine their fair values. The hierarchy, which gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities and the lowest priority to unobservable inputs, is comprised of the following three levels: Level 1 – Unadjusted quoted prices in active markets for identical assets and liabilities. Level 2 – Observable inputs, other than Level 1 inputs, that are directly or indirectly observable for the asset or liability, including quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable. Level 3 – Significant unobservable inputs that reflect the reporting entity’s own assumptions.
