Supplement to the Statutory Prospectus dated December 29, 2015

The following replaces the information contained in the footnote in the prospectus in the section entitled “About your account — Choosing a share class — Class A — Class A sales charges”:

* There is no front-end sales charge when you purchase $1 million or more of Class A shares. However, if Delaware Distributors, L.P. (Distributor) paid your financial intermediary a commission on your purchase of $1 million or more of Class A shares, you will have to pay a Limited CDSC of 1.00% if you redeem these shares of the Delaware Tax-Free Funds and Delaware Minnesota High-Yield Municipal Bond Fund within the first year after your purchase and 0.50% if you redeem shares within the second year; and 0.75% if you redeem shares of Delaware Tax-Free Minnesota Intermediate Fund within the first year after your purchase, unless a specific waiver of the Limited CDSC applies. The Limited CDSC will be paid to the Distributor and will be assessed on an amount equal to the lesser of: (1) the NAV at the time the Class A shares being redeemed were purchased; or (2) the NAV of such Class A shares at the time of redemption. For purposes of this formula, the "NAV at the time of purchase" will be the NAV at purchase of the Class A shares even if those shares are later exchanged for shares of another Delaware Investments® Fund and, in the event of an exchange of Class A shares, the "NAV of such shares at the time of redemption" will be the NAV of the shares acquired in the exchange. In determining whether a Limited CDSC is payable, it will be assumed that shares not subject to the Limited CDSC are the first redeemed followed by other shares held for the longest period of time. See "Dealer compensation" below for a description of the dealer commission that is paid. Sales charges do not apply to shares purchased through dividend reinvestment.
