RATIONAL SPECIAL SITUATIONS INCOME FUND CLASS A SHARES (RFXAX) Exchange: NMFQS

The Fund seeks to achieve its investment objective by primarily investing in agency and non-agency residential and commercial mortgage-backed securities, with a focus on non-agency residential mortgage-backed securities. Non-agency residential mortgage-backed securities are collateralized by pools of residential mortgages which are not insured by government sponsored enterprises or agencies (such as Federal National Mortgage Association (FNMA), Federal Home Loan Mortgage Corporation (FHLMC) and Government National Mortgage Association (GNMA). The Fund’s non-agency mortgage-backed securities investments have a wide variety of payment characteristics and preferences, and can have fixed or floating interest rates. The Fund may also invest in collateralized debt obligations (“CDOs”), collateralized loan obligations (“CLOs”) and other asset-backed securities, including those backed by credit card receivables, auto loans, aircraft leases and student loans. The Fund’s investment sub-advisor, ESM Management, LLC (the "Sub-Advisor"), will allocate the Fund’s investments to asset classes that it views as offering the best values in the marketplace on a relative (risk-adjusted) basis at that time.  The Sub-Advisor seeks to identify, through its own proprietary research and analysis, investments that it believes are undervalued and/or have the potential to achieve an above-market yield over the longer term. The investment strategy seeks to identify “special situations” within fixed income markets, particularly the market for non-agency mortgage-backed securities, where the Fund will make opportunistic investments in securities that may be mispriced due to structural or market driven factors. In this regard, the Sub-Advisor seeks to identify inefficiencies or flaws in the underlying legal and technical structures of certain debt issuances, and then exploit these opportunities while seeking to limit downside exposure. The Sub-Advisor seeks to identify investments where a technical or structural flaw that has gone unnoticed by other market participants, or if the market is aware of the issue, where other participants are, in the opinion of the Sub-Advisor, undervaluing the expected return. The Sub-Advisor will seek to remedy issues it has identified in the security through activist strategies, including (i) bringing the technical issue to the attention of indenture trustees or servicers; (ii) negotiating with the applicable parties to compensate the Fund for the issue; or (iii) through litigation or the threat of litigation. The opportunities that the Sub-Advisor seeks to identify may come in the form of flaws of logic or interpretation in a debt security’s pooling and servicing agreements or bond indentures. Once an investment is identified, the Sub-Advisor estimates various factors, including the investment’s anticipated baseline return, potential upside, probability of upside scenario and investment horizon. Based on this analysis and the market opportunity in terms of outstanding issue size and ability to source the security, the Fund’s investment will be sized based on the Sub-Advisor’s discretion.  The Fund does not limit its investments to a particular credit quality and may invest without limitation in debt securities rated below investment grade (commonly referred to as "junk" bonds). Below investment grade securities include those rated, at the time of purchase, below Baa3 by Moody's Investor Services or equivalently by another nationally recognized statistical rating organization (“NRSRO”), as well as non-rated securities determined by the Sub-Advisor to be of comparable quality. The securities underlying the mortgage- and asset-backed securities in which the Fund invests may include distressed debt securities (i.e., underlying loans and assets that are in default or likely to default). An NRSRO will consider the underlying loans or assets collateralizing a mortgage- or asset-backed security when determining the credit rating of such security. The Sub-Advisor will also take into account the security’s credit rating when evaluating the security for investment by the Fund.  In managing the Fund’s investments, the Sub-Advisor seeks to construct an investment portfolio with a weighted average maturity that ranges between 1 and 30 years and a weighted average effective duration that ranges between -9 and 9 years. Duration measures the price sensitivity of a fixed income security to changes in interest rates. Effective duration is a measure of the Fund’s portfolio duration adjusted for the anticipated effect of interest rate changes on bond and mortgage pre-payment rates. Certain mortgage-related securities in which the Fund may invest such as interest-only securities and related derivatives have “negative duration.” This means that the value of these instruments normally increases as interest rates increase, unlike most other debt instruments. This generally allows some portion of the portfolio’s market risk to be hedged with a purchase, rather than a short sale, and allows the portfolio to realize positive cash flows on the hedge as a result of interest received with respect to that security.  The Fund may also invest in U.S. Treasury and agency securities, structured notes, and over-the-counter and exchange-traded derivative instruments. The Fund will use derivatives for hedging and investment purposes. The Fund may hedge against rising interest rates through interest rate swaps, interest rate-linked futures and call and put options on interest rate futures. The Fund may hedge against rising default rates through credit default swaps, total return swaps linked to an asset or asset class representative of the default risks faced by the Fund, and credit spread options. The Fund may also use one or more of these derivatives as a substitute for or to gain exposure to a security or asset class.  The Fund concentrates its investments in the mortgage-backed securities industry, which includes agency and non-agency mortgage-backed securities.  The Fund is classified as “non-diversified” for purposes of the Investment Company Act of 1940 (the “1940 Act”), which means a relatively high percentage of the Fund’s assets may be invested in the securities of a limited number of issuers.  Distribution Policy: The Fund’s distribution policy is to make twelve monthly distributions to shareholders. The Fund may, at the discretion of management, target a specific level of monthly distributions (including any return of capital) from time to time. Shareholders receiving periodic payments from the Fund may be under the impression that they are receiving net profits. However, all or a portion of a distribution may consist of a return of capital. Shareholders should not assume that the source of a distribution from the Fund is net profit.
