TRIBUTARY BALANCED FUND

(the "Fund")

Supplement dated April 1, 2026 to the Statement of Additional Information ("SAI") dated August 1, 2025, as supplemented

Mr. Kurt Spieler has retired and is no longer a portfolio manager of the Fund. Accordingly, all references in the Prospectus to Mr. Spieler are hereby deleted and the SAI is hereby supplemented as follows:

Portfolio Managers

Ron Horner and Travis Nordstrom of FNA share responsibility for managing the Short-Intermediate Bond Fund, the Income Fund and the Nebraska Tax-Free Fund; Ron Horner and Travis Nordstrom of FNA and Nick Nevole of Tributary are responsible for managing the Balanced Fund; Mark Wynegar and Donald Radtke of Tributary have responsibility of managing the Small/Mid-Cap Fund; and Mark Wynegar and Michael Johnson of Tributary are responsible for managing the Small Company Fund.

Other Accounts Managed. Each portfolio manager also has responsibility for the day-to-day management of accounts other than the Fund(s) for which he or she serves as portfolio manager. The following table provides certain information, as of December 31, 2025, regarding these other accounts.

Conflicts of Interests. When a portfolio manager is responsible for the management of more than one account, the potential arises for the portfolio manager to favor one account over another. Generally, the risks of such conflicts of interests are increased to the extent that the portfolio manager has a financial incentive to favor one account over another. The Company does not believe that any material conflicts are likely to arise out of these portfolio managers' oversight of the other accounts. Those accounts are generally managed relative to different benchmarks and different investment policies which can result in performance variations, but none reported a conflict of interest in investment strategy, asset allocation, or in any other manner. In addition, the Advisers have policies and procedures, enforced by the Advisers' respective compliance departments, designed to address potential conflicts of interest relating to the allocation of investment opportunities by its managers. Further, the Advisers' Code of Ethics address potential conflicts of interest and prohibit certain securities transactions or requires "access persons" to obtain pre-clearance before acquiring beneficial ownership of Fund portfolio securities.

Compensation-Tributary. Each Tributary portfolio manager receives a fixed salary from Tributary based upon experience and prevailing compensation levels in the market. Participation in Tributary's defined contribution (401(k)) plan is voluntary, however, portfolio managers receive an annual contribution by Tributary. Each Tributary portfolio manager is eligible to receive a bonus from Tributary. Performance bonuses are paid yearly and are calculated as a percentage of base salary and are dependent upon performance of the strategy relative to the Fund's benchmark and institutional peer group over 1, 3, and 5 year time periods. In addition, to create an ownership mentality, portfolio managers and all investment professionals at Tributary participate in revenue sharing, whereas a portion of revenue is paid to team members annually.

Compensation-FNA. Each FNA portfolio manager receives a fixed salary from FNA based upon experience and prevailing compensation levels in the market. Participation in FNA's defined contribution (401(k)) plan is voluntary. Each FNA portfolio manager is eligible to receive a bonus from FNA. Bonuses are paid yearly and are calculated as a percentage of base salary and are dependent upon Fund quarterly composite performance relative to that Fund's benchmark and peer group.

The table below shows, as of December 31, 2025, the dollar range of Shares beneficially owned by each portfolio manager in each Fund(s) for which he or she serves as portfolio manager, in one of the following ranges: None; $1-$10,000; $10,001-$50,000; $50,001- $100,000; $100,001-$500,000; $500,001-$1,000,000; or over $1,000,000.
