Strategy. The Fund will invest, under normal market conditions, at least 80% of its net assets (plus the amount of any borrowing for investment purposes) in fixed income securities that pay interest that is exempt from regular federal income tax. The Funds 80% policy is not fundamental and can be changed upon 60 days prior notice to shareholders. The Fund employs a multi-manager strategy whereby the Adviser allocates the Funds assets among professional money managers (each, a Sub-adviser, collectively, the Sub-advisers), each of which is responsible for investing its allocated portion of the Funds assets.

The Funds 80% policy is not fundamental and can be changed upon 60 days prior notice to shareholders. The Fund employs a multi-manager strategy whereby the Adviser allocates the Funds assets among professional money managers (each, a Sub-adviser, collectively, the Sub-advisers), each of which is responsible for investing its allocated portion of the Funds assets. The Adviser may also invest a portion of the Funds assets in unaffiliated funds that are registered under the Investment Company Act of 1940, as amended (the 1940 Act), and that have investment objectives and principal investment strategies consistent with those of the Fund, including open-end funds, closed-end funds and exchange traded funds (ETFs), which may be passively managed (i.e., index-tracking) or actively managed. ETFs may also be used to transition the Funds portfolio or to equitize cash while awaiting an opportunity to purchase securities directly. When determining how to allocate the Funds assets between unaffiliated funds and Sub-advisers, and among Sub-advisers, the Adviser considers a variety of factors. In seeking high current income exempt from regular federal income tax, the Fund will invest in municipal instruments, which are fixed-income obligations issued by a state, territory or possession of the United States (including the District of Columbia) or a political subdivision, agency or instrumentality thereof. Interest income received by holders of municipal instruments is often exempt from the federal income tax and from the income tax of the state in which they are issued (although there may not be a similar exemption under the laws of a particular state or local taxing jurisdiction), although municipal instruments issued for certain purposes may not be tax-exempt. For non-corporate shareholders subject to the federal alternative minimum tax (AMT), a limited portion of the Funds dividends may be subject to federal tax. The Fund primarily invests in investment grade debt obligations, but may invest to a limited extent in obligations that are rated below-investment grade (commonly referred to as junk bonds). A Sub-adviser may sell a security for a variety of reasons, including, but not limited to, where the Sub-adviser believes selling the security will help the Fund to secure gains, limit losses, or redeploy assets into more promising opportunities, or the valuation is no longer attractive. The Funds dollar-weighted average maturity, under normal circumstances, will range between three and thirteen years. In seeking to achieve its investment objective, the Fund may make significant investments in structured securities and also may invest, to a lesser extent, in futures contracts, options and swaps, all of which are considered to be derivative instruments, for both hedging and non-hedging purposes. The Funds investment adviser may engage in active trading and will not consider portfolio turnover a limiting factor in making decisions for the Fund. The Fund may also lend portfolio securities in an attempt to earn additional income. Any income realized through securities lending may help Fund performance. Show less
