of common stocks is sensitive to general movements in the stock market and a drop in the stock market may depress the price of common stocks to which the Acquiring Fund has exposure. Common stock
prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant stock market, or when political or economic events affecting the issuers occur.

The prices of fixed-income securities tend to fall as interest rates rise, and such declines tend to be greater among
fixed-income securities with longer maturities. Market risk is often greater among certain types of fixed-income securities, such as zero coupon bonds that do not make regular interest payments but are instead bought at a discount to their face
values and paid in full upon maturity. As interest rates change, these securities often fluctuate more in price than securities that make regular interest payments and therefore subject the Acquiring Fund to greater market risk than a fund that does
not own these types of securities.

When-issued and delayed delivery transactions are subject to changes in market
conditions from the time of the commitment until settlement, which may adversely affect the prices or yields of the securities being purchased. The greater the Acquiring Fund’s outstanding commitments for these securities, the greater the
Acquiring Fund’s exposure to market price fluctuations.

Selection risk is the risk that the securities that the
Acquiring Fund’s management selects will underperform the equity and/or bond market, the market relevant indices or other funds with similar investment objectives and investment strategies.

Defensive Investing Risk.For defensive purposes, the Acquiring Fund may allocate assets into cash or short-term
fixed-income securities without limitation. In doing so, the Acquiring Fund may succeed in avoiding losses but may otherwise fail to achieve its investment objective. Further, the value of short-term fixed-income securities may be affected by
changing interest rates and by changes in credit ratings of the investments. If the Acquiring Fund holds cash uninvested it will be subject to the credit risk of the depository institution holding the cash.

Decision-Making Authority Risk. Investors have no authority to make decisions or to exercise business discretion on
behalf of the Acquiring Fund, except as set forth in the Acquiring Fund’s governing document. The authority for all such decisions is generally delegated to the Board, which in turn, has delegated the day-to-day management of the Acquiring Fund’s investment activities to the Investment Advisor, subject to oversight by the Board.

Management Risk. The Acquiring Fund is subject to management risk
