Schedule of the fair value hierarchy

The fair value hierarchy is as follows:

Level 1	Valuations for assets and liabilities traded in active exchange markets, or interest in open-end mutual funds that allow a company to sell its ownership interest back at net asset value on a daily basis. Valuations are obtained from readily available pricing sources for market transactions involving identical assets, liabilities or funds.
Level 2	Valuations for assets and liabilities traded in less active dealer, or broker markets, such as quoted prices for similar assets or liabilities or quoted prices in markets that are not active. Level 2 instruments typically include U.S. government and agency debt securities, and corporate obligations. Valuations are usually obtained through market data of the investment itself as well as market transactions involving comparable assets, liabilities or funds.
Level 3	Valuations for assets and liabilities that are derived from other valuation methodologies, such as option pricing models, discounted cash flow models and similar techniques, and not based on market exchange, dealer, or broker-traded transactions. Level 3 valuations incorporate certain assumptions and projections in determining the fair value assigned to such assets or liabilities.
