Fair Value Disclosures [Abstract]
Fair Value Transfer, Policy	Under U.S. GAAP, fair value is defined as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date under current market conditions. A fair value framework is established whereby assets and liabilities measured at fair value are grouped into three levels of a fair value hierarchy, based on the transparency of inputs and the reliability of assumptions used to estimate fair value.

Disclosure of accounting policy for determining when transfers between levels are recognized.
