| Fair Value Disclosures [Text Block] |
FAIR VALUE MEASURES
Certain assets and liabilities are reported at fair value on either a recurring or nonrecurring basis. Fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants, under a three-tier fair value hierarchy that prioritizes the inputs used in measuring fair value as follows:
|
|
|
Level 1 – |
observable inputs such as quoted prices for identical assets or liabilities in active liquid markets; |
Level 2 – |
inputs, other than the quoted market prices in active markets, that are observable, either directly or indirectly; or observable market prices in markets with insufficient volume and/or infrequent transactions; and |
Level 3 – |
unobservable inputs for which there is little or no market data available, that require the reporting entity to
develop its own assumptions.
