Fair Value Disclosures [Abstract]
Fair value measurements description	Assets and liabilities measured at fair value are classified using the fair value hierarchy based upon the transparency of inputs as of the measurement date. The classification of fair value measurements within the hierarchy is based upon the lowest level of input that is significant to the measurement. The three levels are defined as follows: • Level 1 - Valuation is based upon quoted prices (unadjusted) in active markets for identical assets or liabilities. • Level 2 - Valuation is based upon quoted prices for similar assets and liabilities in active markets, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. • Level 3 - Valuation is based upon unobservable inputs that are significant to the fair value measurement.

For each line item in the statement of financial position that includes an item or items for which the fair value option has been elected, this element represents information to enable users of the financial statements to understand how each line item in the statement of financial position relates to major categories of assets and liabilities in terms of the fair value measurement hierarchy. The fair value measurement hierarchy consists of three levels including: using quoted prices in active markets for identical assets (Level 1), significant other observable inputs (Level 2), and significant unobservable inputs (Level 3). Where the quoted price in an active market for the identical liability is not available, the Level 1 input is the quoted price of an identical liability when traded as an asset.
