Important information on risk

Past performance is no guarantee of future results. All investments carry a certain degree of risk, including the possible loss of principal, and there is no assurance that an investment will provide positive performance over any period of time. Certain products and services may not be available to all entities or persons. There is no guarantee that investment objectives will be achieved.

Closed-end funds frequently trade at a discount from net asset value (NAV). At any point in time, including when sold, shares may be worth more or less than the purchase price or the net asset value, even after considering the reinvestment of fund distributions. It is important to consider the objectives, risks, charges and expenses of any fund before investing.
