NOTE:  INVESTMENT IN SECURITIES (unaudited)
At April 29, 2022, the net unrealized appreciation (depreciation) based on the cost of investments for federal income tax purposes was as follows:
	Kansas Municipal Fund	Maine Municipal Fund	Nebraska Municipal Fund	Oklahoma Municipal Fund	Viking Tax-Free Fund for Montana	Viking Tax-Free Fund for North Dakota
Investments at cost	$70,836,123	$11,810,324	$53,856,950	$65,188,954	$82,849,103	$30,201,041

*Differences between financial reporting-basis and tax-basis unrealized appreciation/(depreciation) are due to differing treatment of 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 29, 2022:
