Principal Risk Factors: Risks are inherent in all investing. Certain risks applicable to the Fund are identified below, which includes the risk that you could lose some or all of your investment in the Fund. The principal risks of investing in the Fund are spelled out in the Fund's annual shareholder reports. The order of the below risk factors does not indicate the significance of any particular risk factor. The Fund also files reports, proxy statements and other information that is available for review.

Past performance is no assurance of future results. Investment return and market value of an investment in the Fund will fluctuate. Shares, when sold, may be worth more or less than their original cost. There can be no assurance that the Fund's investment objectives will be achieved. The Fund may not be appropriate for all investors.

Market risk is the risk that a particular investment, or shares of a fund in general may fall in value. Investments held by the Fund are subject to market fluctuations caused by real or perceived adverse economic conditions, political events, regulatory factors or market developments, changes in interest rates and perceived trends in securities prices. Shares of a fund could decline in value or underperform other investments as a result. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious disease or other public health issues, recessions, natural disasters or other events could have significant negative impact on a fund and its investments.

Current market conditions risk is the risk that a particular investment, or shares of the fund in general, may fall in value due to current market conditions. For example, changes in governmental fiscal and regulatory policies, disruptions to banking and real estate markets, actual and threatened international armed conflicts and hostilities, and public health crises, among other significant events, could have a material impact on the value of the fund's investments.

Preferred/hybrid and debt securities in which the Fund invests are subject to various risks, including credit risk, interest rate risk, and call risk. Credit risk is the risk that an issuer of a security will be unable or unwilling to make dividend, interest and/or principal payments when due and that the value of a security may decline as a result. Credit risk may be heightened for the Fund because it invests in below investment grade securities, which involve greater risks than investment grade securities, including the possibility of dividend or interest deferral, default or bankruptcy. Interest rate risk is the risk that the value of fixed-rate securities in the Fund will decline because of rising market interest rates. Call risk is the risk that performance could be adversely impacted if an issuer calls higher-yielding debt instruments held by the Fund. These securities are also subject to issuer risk, floating rate and fixed-to-floating rate risk, prepayment risk, reinvestment risk, subordination risk and liquidity risk.

The risks associated with trust preferred securities typically include the financial condition of the financial institution that creates the trust, as the trust typically has no business operations other than holding the subordinated debt issued by the financial institution and issuing the trust preferred securities and common stock backed by the subordinated debt.

Interest rate risk is the risk that securities will decline in value because of changes in market interest rates. The duration of a security will be expected to change over time with changes in market factors and time to maturity. Although the Fund seeks to maintain a duration, under normal market circumstances, excluding the effects of leverage, of between three and eight years, if the effect of the Fund's use of leverage was included in calculating duration, it could result in a longer duration for the Fund.

Because the Fund is concentrated in the financials sector, it will be more susceptible to adverse economic or regulatory occurrences affecting this sector, such as changes in interest rates, loan concentration and competition.

Investment in non-U.S. securities is subject to the risk of currency fluctuations and to economic and political risks associated with such foreign countries.

Investments in securities of issuers located in emerging market countries are considered speculative and there is a heightened risk of investing in emerging markets securities. Financial and other reporting by companies and government entities also may be less reliable in emerging market countries. Shareholder claims that are available in the U.S., as well as regulatory oversight and authority that is common in the U.S., including for claims based on fraud, may be difficult or impossible for shareholders of securities in emerging market countries or for U.S. authorities to pursue.

Contingent Capital Securities provide for mandatory conversion into common stock of the issuer under certain circumstances, which may limit the potential for income and capital appreciation and, under certain circumstances, may result in complete loss of the value of the investment.

Reverse repurchase agreements involve leverage risk, the risk that the purchaser fails to return the securities as agreed upon, files for bankruptcy or becomes insolvent. The Fund may be restricted from taking normal portfolio actions during such time, could be subject to loss to the extent that the proceeds of the agreement are less than the value of securities subject to the agreement and may experience adverse tax consequences.

Use of leverage can result in additional risk and cost, and can magnify the effect of any losses.

The risks of investing in the Fund are spelled out in the shareholder reports and other regulatory filings.
