Level 1	–	unadjusted quoted prices in active markets for identical securities.
Level 2	–	other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).
Level 3	–	significant unobservable inputs (including the Adviser's own assumptions in determining fair value of investments).

The following is a summary of the inputs used as of January 31, 2023, in valuing the Fund's investments:

Balance as of 1/31/23	$ 256,669	$ 11,847,095	$ 12,103,764

*	Transfers are calculated on the beginning of period values. During the period ended January 31, 2023 investments having aggregate value of $33 were transferred out of Level 3 to Level 2, as there  were significant observable inputs available to determine their value. Investments having aggregate value of $395,000 were transferred from Level 1 to Level 3, due to valuing the security using unobservable inputs, resulting from a decrease in market activity for the securities. There were no other transfers into or out of Level 3 during the period.
Net change in unrealized appreciation (depreciation) of Level 3 investments still held and considered Level 3 at January 31, 2023:		$ (500,986)
