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)
