Various inputs are used in determining the value of the Fund’s investments. These inputs are summarized in the three broad levels below.

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 June 30, 2024 in valuing the Fund’s investments:

	Level 1	Level 2	Level 3	Total
Municipal Bonds	$—	$267,988,552	$1	$267,988,553
Total Investments in Securities	$—	$267,988,552	$1	$267,988,553

Net unrealized appreciation on futures contracts	$193,355	$—	$—	$193,355
Total Other Financial Instruments	$193,355	$—	$—	$193,355

Transfers are calculated on the beginning of period values. During the period ended June 30, 2024, a security valued at $696 was transferred from Level 2 to Level 3, due to valuing the security using observable inputs. There were no other transfers in or out of Level 3 during the period.
