The list of investments, investment practices and risks under MISCELLANEOUS INVESTMENTS, INVESTMENT PRACTICES AND RISKS is supplemented to include “Exchange Traded Notes.”

The section MISCELLANEOUS INVESTMENTS, INVESTMENT PRACTICES AND RISKS is supplemented to include the following:

Exchange Traded Notes

The fund may invest in exchange traded notes (“ETNs”). ETNs are typically senior, unsecured, unsubordinated debt securities whose returns are linked to the performance of a particular market index less applicable fees and expenses. ETNs are listed on an exchange and traded in the secondary market. The Fund may hold the ETN until maturity, at which time the issuer is obligated to pay a return linked to the performance of the relevant market index. ETNs do not make periodic interest payments and principal is not protected.

The market value of an ETN may be influenced by, among other things, time to maturity, level of supply and demand of the ETN, volatility and lack of liquidity in the underlying assets, changes in the applicable interest rates, the current performance of the market index to which the ETN is linked, and the credit rating of the ETN issuer. The market value of an ETN may differ from the performance of the applicable market index and there may be times when an ETN trades at a premium or discount. This difference in price may be due to the fact that the supply and demand in the market for ETNs at any point in time is not always identical to the supply and demand in the market for the securities underlying the market index that the ETN seeks to track. A change in the issuer’s credit rating may also impact the value of an ETN despite the underlying market index remaining unchanged. ETNs are also subject to tax risk. No assurance can be given that the IRS will accept, or a court will uphold, how the Funds characterize and treat ETNs for tax purposes.

An ETN that is tied to a specific market index may not be able to replicate and maintain exactly the composition and relative weighting of securities, commodities or other components in the applicable market index. ETNs also incur certain expenses not incurred by their applicable market index, and the fund would bear a proportionate share of any fees and expenses borne by the ETN in which it invests.

The fund’s decision to sell its ETN holdings may be limited by the availability of a secondary market. In addition, although an ETN may be listed on an exchange, the issuer may not be required to maintain the listing and there can be no assurance that a secondary market will exist for an ETN. Some ETNs that use leverage in an effort to amplify the returns of an underlying market index can, at times, be relatively illiquid and may therefore be difficult to purchase or sell at a fair price. Leveraged ETNs may offer the potential for greater return, but the potential for loss and speed at which losses can be realized also are greater.

ETNs are generally similar to structured investments and hybrid instruments. For discussion of these investments and the risks generally associated with them, see “Hybrid Instruments” and “Structured Investments” in this SAI.
