in markets that are active, quoted prices for identical or similar assets or liabilities 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 circumstances, to the
extent observable inputs are not available (including the Fund's own assumptions used in
determining the fair value of investments)
