The Fund's investment manager, Delaware Management Company (Manager), is contractually waiving its investment advisory fees and/or paying expenses (excluding any 12b-1 plan, taxes, interest, inverse floater program expenses, short sale and dividend interest expenses, brokerage fees, certain insurance costs, acquired fees and expenses, and nonroutine expenses or costs, including, but not limited to, those relating to reorganizations, litigation, conducting shareholder meetings, and liquidations) to the extent necessary to prevent total annual fund operating expenses from exceeding 0.65% of the Fund's average daily net assets from November 28, 2012 through November 28, 2013. The Fund's distributor, Delaware Distributors, L.P. (Distributor), has contracted to limit the Fund's Class B shares' 12b-1 fee to no more than 0.25% of average daily net assets from March 1, 2013 through February 28, 2014. These waivers and reimbursements may only be terminated by agreement of the Manager and the Distributor, as applicable, and the Fund. Additionally, the Fund's Class A shares are subject to a blended 12b-1 fee of 0.10% on all shares acquired prior to June 1, 1992, and 0.25% on all shares acquired on or after June 1, 1992. This method of calculating Class A 12b-1 fees may be discontinued at the sole discretion of the Board.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and reflects the applicable waivers and reimbursements for the 1-year contractual period and the total operating expenses without waivers for years 2 through 10. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

		(if not		(if not
		redeemed)		redeemed)
Class	A	B	B	C	C	R	Inst.
1 year	$538	$92	$492	$168	$268	$117	$66
3 years	$771	$496	$721	$569	$569	$414	$258
5 years	$1,023	$925	$1,075	$995	$995	$733	$465
10 years	$1,743	$1,924	$1,924	$2,182	$2,182	$1,637	$1,063

Dealer compensation

The financial advisor that sells you shares of the Fund may be eligible to receive the following amounts as compensation for your investment in the Fund. These amounts are paid by the Distributor to the securities dealer with whom your financial advisor is associated. Institutional Class shares do not have a 12b-1 fee or sales charge so they are not included in the chart below.

1	On sales of Class A shares, the Distributor reallows to your securities dealer a portion of the front-end sales charge depending upon the amount you invested. Your securities dealer may be eligible to receive a 12b-1 fee of up to 0.25% from the date of purchase.
2	On sales of Class B shares, the Distributor may pay your securities dealer an up-front commission of 4.00%. Your securities dealer may be eligible to receive a 12b-1 service fee of up to 0.25% from the date of purchase. After approximately eight years, Class B shares automatically convert to Class A shares and dealers may then be eligible to receive the 12b-1 fee applicable to Class A shares.

3

On sales of Class C shares, the Distributor may pay your securities dealer an up-front commission of 1.00%. The up-front commission includes an advance of the first year's 12b-1 service fee of up to 0.25%. During the first 12 months, the Distributor retains the full 1.00% 12b-1 fee to partially offset the up-front commission and the prepaid 0.25% service fee advanced at the time of purchase. Starting in the 13th month, your securities dealer may be eligible to receive the full 1.00% 12b-1 fee applicable to Class C. Alternatively, certain intermediaries may not be eligible to receive the up-front commission of 1.00%, but may receive the 12b-1 fee for sales of Class C shares from the date of purchase.

4

On sales of Class R shares, the Distributor does not pay your securities dealer an up-front commission. Your securities dealer may be eligible to receive a 12b-1 fee of up to 0.50% from the date of purchase.
