(1)
Level 1 instruments use observable market prices for the identical item in active markets and have the most reliable valuations.
(2)
Level 2 instruments are valued through broker/dealer quotation or through market-observable inputs for similar items in active markets. Equity securities categorized as Level 2 assets are primarily non-exchange-traded commingled or collective funds where the underlying securities have observable prices available from active markets. Valuation is based on the net asset value of fund units held as derived from the fair value of the underlying assets.
