(2)	Marketable Securities

Fair value accounting standards define fair value 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. The following fair value hierarchy prioritizes the inputs used to measure fair value into three levels, with Level 1 being of the highest priority. The three levels of inputs used to measure fair value are as follows:


Level 1 –		Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2 –		Include other inputs that are directly or indirectly observable in the marketplace.

Level 3 –		Unobservable inputs which are supported by little or no market activity.

The level in the fair value hierarchy within which a fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety.

The following table presents the placement in the fair value hierarchy of assets that are measured at fair value on a recurring basis at period end:


			Level 1		Level 2		Level 3
