Various inputs are used in determining the fair value of investments, which are as follows:

	•	Level 1 - price quotations in active markets/exchanges for identical securities

	•	Level 2 - other observable inputs (including, but not limited to: quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs)

	•	Level 3 - unobservable inputs based on the best information available in the circumstance, to the extent observable inputs are not available (including the Trust’s own assumption used in determining the fair value of investments)
