●	Level 1 —includes instruments with quoted prices in active markets for identical assets.

●

Level

— includes instruments for which the valuations are based upon quoted market prices in active markets involving similar

assets or inputs other than quoted prices that are observable for the assets.

The market inputs used to value these instruments

general

ly consist of market yields, recently executed transactions, broker/dealer quotes or alternative pricing sources with

reasonable levels of price transparency. Pricing sources

may

include industry standard data providers, security master files

from

large

financial institutions, and other

third

party sources used to determine a daily market value.

●	Level 3 —includes instruments for which the valuations are based on inputs that are unobservable and significant to the overall fair value measurement.
