NOTE: INVESTMENT IN SECURITIES (unaudited)

At April 30, 2026, the net unrealized appreciation/(depreciation) based on the cost of investments for federal income tax purposes was as follows:

Oklahoma Municipal Fund

Investments at cost

Unrealized depreciation

(134,441)

Net unrealized appreciation/(depreciation)*

$

551,971

*Differences between financial reporting-basis and tax-basis unrealized appreciation/(depreciation) are due to differing treatment of wash sales and market discount.

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 April 30, 2026:

Oklahoma Municipal Fund

Level 1

Level 2

Level 3
