NOTE: FAIR VALUE MEASUREMENTS (unaudited)
Various inputs are used in determining the value of the Funds' investments. These inputs are summarized in three broad levels: Level 1 inputs are based on quoted prices in active markets for identical securities. Level 2 inputs are based on significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.) Level 3 inputs are based on significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments.) The following is a summary of the inputs used to value the Funds’ investments as of October 29, 2021:
