The waiver does not include front end or contingent deferred loads, taxes, interest, dividend expenses, brokerage commissions, acquired fund fees and expenses, or expenses incurred in connection with any merger, reorganization, or extraordinary expenses such as litigation. Any amounts waived or reimbursed by the Adviser are subject to reimbursement by the Fund within the following three years, provided the Fund is able to make such reimbursement and remain in compliance with the expense limitations stated above. The Operating Expenses Agreement may be terminated at any time, by the Board of Directors, on behalf of the Fund, upon sixty days written notice to the Adviser.

Example:

This Example is intended to help you compare the cost of investing in the Income Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Income Fund for the time periods indicated and that you sell your shares at the end of those periods. The example also assumes that each year your investment has a 5% return, Fund operating expenses remain the same and the expense waiver/reimbursement remains in place for only the first year. Although your actual costs and returns might be different, your approximate costs of investing $10,000 in the Income Fund would be:

1 Year 3 Years 5 Years 10 Years
Class A Shares $586 $861 $1,156 $1,994
Class C Shares - no redemption $192 $636 $1,105 $2,405
Class C Shares - with redemption $292 $636 $1,105 $2,405
Institutional Shares $92 $328 $582 $1,312

Portfolio Turnover:

The Income Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Income Fund Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Income Fund's performance. During the most recent fiscal year ended December 31, 2025, the Income Fund's portfolio turnover rate was 0% of the average value of its portfolio.

Principal Investment Strategies:

The Income Fund seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its assets in a portfolio of taxable municipal bonds, income producing convertible securities, preferred stocks, high yield U.S. corporate bonds (i.e., "junk bonds"), and collateralized mortgage obligations ("CMOs"). A CMO is a mortgage-backed bond that separates mortgage pools into different maturity classes. Payments of principal and interest are passed through to each bond issue at varying schedules resulting in bonds with different coupons, effective maturities and sensitivities to interest rates. CMOs issued by U.S. government agencies are backed by agency mortgages, while privately issued CMOs may be backed by either government agency mortgages or private mortgages. The Income Fund may also invest in U.S. government agency securities issued or guaranteed by U.S. government-sponsored enterprises and federal agencies, including securities issued by the Federal National Mortgage Association ("FNMA"), the Federal Home Loan Mortgage Corporation ("FHLMC"), and the Government National Mortgage Association ("GNMA"). Some of these securities are supported by the full faith and credit of the U.S. Treasury; the remainder are supported only by the credit of the instrumentality, which may or may not include the right of the issuer to borrow from the U.S. Treasury. These also include securities issued by eligible private depository institutions and guaranteed by the Federal Deposit Insurance Corporation ("FDIC").

Income Fund | www.soafunds.com

High yield bonds are rated below investment grade (BB and lower). The Portfolio Manager seeks out high yield bonds with the potential to offer high current income, generally focusing on high yield bonds that can provide consistently attractive current yields. High yield bonds offer high income in an effort to compensate investors for the higher risk of default (failure to make required interest or principal payments). The Income Fund may also invest in higher rated (above BB) bonds. Although the Income Fund expects to maintain a long-weighted average maturity, there are no maturity restrictions on the Income Fund or on individual securities. Typically, the investments in the Income Fund will be subject to federal income taxation.

The Income Fund may also invest in master limited partnerships ("MLPs"), equity securities of dividend paying companies and private placements.

Principal Risks of Investing in the Income Fund:

An investment in the Income Fund could lose money over short or long periods of time. You should expect and be able to bear the risk that the Income Fund's share price will fluctuate within a wide range. There is no assurance that the Income Fund will achieve its investment objective. The Income Fund's performance could be adversely affected by the following principal risks. Each risk summarized below is a principal risk of investing in the Income Fund and different risks may be more significant at different times depending upon market conditions or other factors.

Interest Rate Risk - Interest rate risk is the possibility that overall bond prices will decline because of rising interest rates. Even GNMAs and other agency securities (whose principal and interest payments are guaranteed) can decline in price if rates rise. Interest rate risk is expected to be high for the Income Fund because it invests, without limitation, in long-term bonds, whose prices are much more sensitive to interest fluctuations than are the prices of short-term bonds.
Credit Risk - Credit risk is the possibility that the issuer of a bond will fail to pay interest and principal in a timely manner, or that negative perceptions of the issuer's ability to make such payments will cause the price of that bond to decline. Credit risk is significant for the Income Fund because it seeks to invest a portion of the Income Fund's assets in low-quality bonds. Even if there is no actual default, it is probable that a bond will decline in price if its credit quality declines and its bond rating is downgraded to a lower category. The Income Fund attempts to reduce portfolio credit risk by diversifying its holdings and carefully researching issuer credit quality.
Call Risk - Call risk is the possibility that during periods of falling interest rates, issuers of callable bonds may call (redeem) higher coupon rate bonds before their maturity dates. The Income Fund would then lose potential price appreciation and would be forced to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the Income Fund's income. Call risk is typically higher for long-term bonds.
Dividend Payment Risk - The risk that a portfolio holding is unable to maintain dividend payments at historical levels.
Market Risk - The market value of the Income Fund's investments will fluctuate as the respective markets fluctuate. Market risk may affect a single issuer, industry or sector of the economy or it may affect the market as a whole. Performance of the Income Fund can be affected by unexpected local, state, regional, national or global events (e.g., significant earnings shortfalls or gains, inflation, recessions, government shutdowns, market closures, market manipulation and other fraudulent practices, war, military conflict, political and geopolitical events, acts of terrorism, the spread of infectious diseases or other public health issues, natural and environmental disasters, trade disputes, tariff arrangements, sanctions, and cybersecurity attacks) that cause major price changes in individual securities or market sectors. The securities purchased by the Income Fund may not appreciate in value as the Adviser anticipates. For additional information regarding Market Risk, refer to "Market Risk" in the section titled "Additional Information About the Investment Objectives, Principal Investment Strategies and Related Risks of the Funds" in the Fund's prospectus.
Credit Risks of Lower-Grade Securities - Credit risks of lower-grade securities is the possibility that bonds rated below investment grade, or unrated of similar quality (i.e., "junk bonds"), may be subject to greater price fluctuations and risks of loss of income and principal than investment-grade securities. High yield bond issuers often include small or relatively new companies lacking the operating history or capital to warrant investment grade status, former blue chip companies downgraded because of financial problems, companies electing to borrow heavily to finance or avoid a takeover or buyout, and firms with heavy debt loads. Securities that are (or that have fallen) below investment-grade have a greater risk that the issuers may not meet their debt obligations. These types of securities are generally considered speculative in relation to the issuer's ongoing ability to make principal and

interest payments. During periods of rising interest rates or economic downturn, the trading market for these securities may not be active and may reduce the Income Fund's ability to sell these securities (see "Liquidity Risk", described under "Additional Information about the Investment Objectives, Principal Investment Strategies and Related Risks of the Income Fund" below) at an acceptable price. If the issuer of securities is in default in payment of interest or principal, the Income Fund may lose its entire investment in those securities.

Preferred Securities Risk - Preferred securities can decrease in value for a variety of reasons, including decreases in response to the activities of an individual company or in response to general market and/or economic conditions. The market value of all securities, including preferred securities, is based upon the market's perception of value and not necessarily the book value of an issuer or other objective measures of a company's worth. Preferred securities may be less liquid than common securities and may be subject to more fluctuations in market value, due to changes in market participants' perceptions of the issuer's ability to continue to pay dividends, than debts of the same issuer.
Equity Securities Risk - Equity securities are susceptible to general market fluctuations and volatile increases and decreases in value as market confidence in and perceptions of their issuers change. Factors that may influence the price of equity securities include developments affecting a specific company or industry, or changing economic, political or market conditions.
MLP Risk - Investing in MLPs involve risks that differ from investments in common stock including risks related to limited control and limited rights to vote on matters affecting the MLP, risks related to potential conflicts of interest between the MLP and the MLP's general partner, cash flow risks, dilution risks and risks related to the general partner's limited call right, as described in more detail in the prospectus. In addition, investments in MLPs subject the Income Fund to risks associated with the specific industry or industries in which the MLPs invest. MLPs are generally considered interest-rate sensitive investments. During periods of interest rate volatility, these investments may not provide attractive returns.
Portfolio Management Risk - The Income Fund's ability to achieve its investment objective is dependent on the Adviser's ability to identify profitable investment opportunities for the Fund. The securities purchased by the Adviser may not perform as anticipated.
Private Placement Risk  - Private placement risk is the risk that investments in private placements are illiquid. Privately placed securities may be difficult to sell promptly or at reasonable prices and might thereby cause the Income Fund difficulty in satisfying redemption requests. Privately placed securities are typically fair valued and generally have no secondary trading market; therefore, such investments may be more difficult to value than publicly traded securities. Difficulty in valuing a private placement may make it difficult to accurately determine the Income Fund's exposure to private placement investments, which could cause it to invest to a greater extent than permitted in illiquid investments and subject it to increased risks. Private placement investments may involve a high degree of business and financial risk and may result in substantial losses. These factors may have a negative effect on the Income Fund's performance.
Risks of CMOs - Risks of CMOs is the possibility that the Income Fund will be less likely to receive payments of principal and interest, and will be more likely to suffer a loss, if there are defaults on the mortgage loans underlying the CMOs. This risk may be increased to the extent that the underlying mortgages include sub-prime mortgages and in relation to the level of subordination of the category of the CMOs held by the Income Fund. In addition, CMOs may be less liquid or may exhibit greater price volatility than other types of mortgages or asset-backed securities. Some CMOs may be structured in a way that when interest rates change, the impact of changing prepayment rates on the effective maturities of certain issues of these securities is magnified. CMO risk also depends on the issuer. While CMO collateral is typically issued by GNMA, FNMA or FHLMC, the CMO itself may be issued by a private party, such as a brokerage firm, that is not covered by government guarantees. CMO collateral may also include different or specialized types of mortgage loans or mortgage loan pools, letters of credit, or other types of credit enhancements and these so called "private label" CMOs are the sole obligation of their issuer.
U.S. Government Securities Risk - Although U.S. Government securities are considered among the safest investments, they are not guaranteed against price movements due to changing interest rates. Obligations issued by some U.S. Government agencies are backed by the U.S. Treasury, while others are backed solely by the ability of the agency to borrow from the U.S. Treasury or by the agency's own resources.
