Strategy. Under normal market conditions, the Fund pursues its investment objective by investing primarily in closed -end registered investment companies (closed -end funds or CEFs) that invest primarily in municipal bonds. Municipal bonds are debt obligations issued by the states, possessions, or territories of the United States (including the District of Columbia) or a political subdivision, public instrumentality, agency, public authority or other governmental unit of such states, possessions, or territories (e.g., counties, cities, towns, villages, districts and authorities). In addition, when, in the opinion of Robinson Capital Management, LLC (Robinson or the Sub -Advisor ), the Funds sub -advisor , the risk/reward profile for CEF securities appears unfavorable, or when CEF price valuations are not attractive, the Fund may, but … Show more… Under normal market conditions, the Fund pursues its investment objective by investing primarily in closed -end registered investment companies (closed -end funds or CEFs) that invest primarily in municipal bonds. Municipal bonds are debt obligations issued by the states, possessions, or territories of the United States (including the District of Columbia) or a political subdivision, public instrumentality, agency, public authority or other governmental unit of such states, possessions, or territories (e.g., counties, cities, towns, villages, districts and authorities). In addition, when, in the opinion of Robinson Capital Management, LLC (Robinson or the Sub -Advisor ), the Funds sub -advisor , the risk/reward profile for CEF securities appears unfavorable, or when CEF price valuations are not attractive, the Fund may, but is not required to, purchase shares of open -end registered investment companies (Mutual Funds) or Exchange -Traded Funds (ETFs) that invest primarily in municipal bonds. The Fund expects a substantial portion of the income generated by the municipal bonds in which the CEFs, Mutual Funds and ETFs invest will be exempt from federal income taxes (tax advantaged income). A portion of the income generated by these municipal bonds, however, may be subject to the alternative minimum tax. As a result, the CEFs, Mutual Funds and ETFs distributions to investors are expected to consist primarily of tax advantaged income, and a substantial portion of the income distributed to the Fund and Fund shareholders is also expected to consist primarily of such tax advantaged income. The CEFs, Mutual Funds and ETFs in which the Fund invests invest primarily in investment grade municipal bonds, with an average rating of at least Baa3 or higher by Moodys or BBB- or higher by Standard & Poors or Fitch Ratings. Certain Mutual Funds and ETFs in which the Fund may choose to invest may have exposure to municipal bonds that are rated below investment grade (junk bonds). Typically, the Sub -Advisor expects to limit the Funds exposure to junk bonds held by the underlying CEFs, Mutual Funds, and ETFs to no more than 15% of the market value of the Funds portfolio. There is no minimum or maximum average maturity for the underlying municipal bond holdings in the CEFs, Mutual Funds and ETFs in which the Fund invests. To seek to hedge against interest rate risk and mitigate the Funds exposure to duration risk, the Sub -Advisor may use short positions and invest in short -term investments and derivatives such as options, futures contracts, options on futures contracts, and swaps. Primarily the Sub -Advisor anticipates using short positions on U.S. Treasury futures contracts (generally 2 -year note, 5 -year note, 10 -year note and 30 -year bond contracts) for those purposes. The Sub -Advisor may also use options on municipal bond ETFs, interest rate swaps, and the purchase of credit default swaps. Typically, the Sub -Advisor expects to limit these positions to no more than 10% of the market value of the Funds portfolio. Whether analyzing CEFs, Mutual Funds or ETFs, the Sub -Advisor looks through to the underlying holdings of the funds. Holdings are analyzed across a variety of risk and return metrics including interest rate risk, call risk, credit quality, yield to maturity and yield to worst, to ensure the holdings are consistent with the Funds policies. For the CEFs, the Sub -Advisor s portfolio construction process involves using proprietary real -time models to first analyze and rank CEFs to build expected return and risk profiles. The Sub -Advisor then uses value oriented analysis to weigh the costs and benefits of the CEFs, and quantify the CEFs exposure to various risks. The Sub -Advisor seeks to select CEFs that trade at discounts to the true market values of the CEFs municipal bond holdings by identifying quantifiable (or rational) factors that could contribute to a deviation between a CEFs market capitalization ( i.e., the aggregate market price of its total outstanding shares) and the true market value of the municipal bonds that the CEF holds. Such factors include the CEFs historical performance, fund expenses, dividend distribution yield, unrealized capital gains, investor trading to harvest short term losses, cost and use of leverage, liquidity, and governance. The Sub -Advisor s proprietary valuation model seeks to quantify each of these factors and adds them to (or if the factors have a negative impact, subtracts them from) a CEFs underlying market value. The resulting valuation is what the Sub -Advisor considers the fair market value for the CEF. The calculated fair market value per fund share is then compared to the actual price at which the CEFs shares are currently trading. The Sub -Advisor believes that any difference can be attributed to irrational explanations. If the Sub -Advisor s determination of a CEFs fair market value is greater than the CEFs actual market price, the Sub -Advisor considers the difference to be the CEFs discount. Conversely, if the Sub -Advisor s determination of a CEFs fair market value is lower than the actual market price, the Sub -Advisor considers the difference to be the CEFs premium. The Sub -Advisor then analyzes the data according to its own proprietary model to determine a rating of the discount or premium. The analysis includes how under/overvalued a CEF is relative to its history, how under/overvalued a CEF is relative to other CEFs in the same asset class, how under/overvalued the asset class is relative to its history, and how under/overvalued the asset class is to other asset classes. The Sub -Advisor may utilize a number of trading techniques to seek to unlock its estimate of the value of the premiums/discounts in the CEFs that invest in municipal bonds. This may lead to active and frequent trading of the Funds securities. The Sub -Advisor s techniques include rotating Fund portfolio holdings to the CEFs the Sub -Advisor believes are the most undervalued, short selling those CEFs that the Sub -Advisor believes are the most overvalued, opportunistic trading due to temporary price dislocations, participating in tender offers of CEF shares, arbitrage opportunities for CEF mergers, buying a CEF that the Sub -Advisor believes is undervalued and pairing it with a short position in another CEF, and tax -related rebalancing trades. The Fund may engage in frequent and active trading. Show less
