Supplement To each Fund’s Statement of Additional Information

Securities Lending. The Fund may lend portfolio securities in an amount up to one-third of its total assets to brokers, dealers and other financial institutions. In a portfolio securities lending transaction, the Fund receives from the borrower an amount equal to the interest paid or the dividends declared on the loaned securities during the term of the loan as well as the interest on the collateral securities, less any fees (such as finders or administrative fees) the Fund pays in arranging the loan. The Fund may share the interest it receives on the collateral securities with the borrower. The terms of the Fund’s loans permit the Fund to reacquire loaned securities on five business days’ notice or in time to vote on any important matter. Loans are subject to termination at the option of the Fund or borrower at any time, and the borrowed securities must be returned when the loan is terminated. The Fund may pay fees to arrange for securities loans.

The SEC currently requires that the following conditions must be met whenever the Fund’s portfolio securities are loaned: (1) the Fund must receive at least 100% cash collateral from the borrower; (2) the borrower must increase such collateral whenever the market value of the securities rises above the level of such collateral; (3) the Fund must be able to terminate the loan at any time; (4) the Fund must receive reasonable interest on the loan, as well as any dividends, interest or other distributions on the loaned securities, and any increase in market value; (5) the Fund may pay only reasonable custodian fees approved by the Board in connection with the loan; (6) while voting rights on the loaned securities may pass to the borrower, the Board must terminate the loan and regain the right to vote the securities if a material event adversely affecting the investment occurs, and (7) the Fund may not loan its portfolio securities so that the value of the loaned securities is more than one-third of its total asset value, including collateral received from such loans. These conditions may be subject to future modification. Such loans will be terminable at any time upon specified notice. The Fund might experience the risk of loss if the institution with which it has engaged in a portfolio loan transaction breaches its agreement with the Fund. In addition, the Fund will not enter into any portfolio security lending arrangement having a duration of longer than one year. The principal risk of portfolio lending is potential default or insolvency of the borrower. In either of these cases, the Fund could experience delays in recovering securities or collateral or could lose all or part of the value of the loaned securities. As part of participating in a lending program, the Fund may be required to invest in collateralized debt or other securities that bear the risk of loss of principal. In addition, all investments made with the collateral received are subject to the risks associated with such investments. If such investments lose value, the Fund will have to cover the loss when repaying the collateral.

Any loans of portfolio securities are fully collateralized based on values that are marked-to-market daily. Any securities that the Fund may receive as collateral will not become part of the Fund’s investment portfolio at the time of the loan and, in the event of a default by the borrower, the Fund will, if permitted by law, dispose of such collateral except for such part thereof that is a security in which the Fund is permitted to invest. During the time securities are on loan, the borrower will pay the Fund any accrued income on those securities, and the Fund may invest the cash collateral and earn income or receive an agreed-upon fee from a borrower that has delivered cash-equivalent collateral.

The Fund may participate in securities lending arrangements whereby the Fund lends certain of its portfolio securities to brokers, dealers, and financial institutions (not with individuals) to receive additional income and increase the rate of return of its portfolio. U.S. Bank serves as the Fund’s’ securities lending agent and is responsible for (i) negotiating the fees (rebates) of securities loans within parameters approved by the Board; (ii) delivering loaned securities to the applicable borrower(s), a list of which has been approved by the Board; (iii) investing any cash collateral received for a securities loan in investments pre-approved by the Board; (iv) receiving the returned securities at the expiration of a loan’s term; (v) daily monitoring of the value of the loaned securities and the collateral received; (vi) notifying borrowers to make additions to the collateral, when required; (vii) accounting and recordkeeping services as necessary for the operation of the securities lending program, and (viii) establishing and operating a system of controls and procedures to ensure compliance with its obligations under the Fund’s securities lending program.
