What are the Fund's fees and expenses?

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales-charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Delaware Investments® Funds. More information about these and other discounts is available from your financial advisor, in the Fund's prospectus under the section entitled "About your account," and in the Fund's statement of additional information under the section entitled "Purchasing shares."

The Fund's investment manager, Delaware Management Company (Manager), is voluntarily waiving its investment advisory fees and/or paying expenses (excluding any 12b-1 fees, taxes, interest, short sale and dividend interest expenses, brokerage fees, certain insurance costs, 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 0.95% of the Fund's average daily net assets from August 28, 2012 until such time as the voluntary expense cap is discontinued. In addition, the Fund's distributor, Delaware Distributor, L.P. (Distributor), has voluntarily agreed to waive all 12b-1 fees. After giving effect to the Manager's and Distributor's voluntary waivers, the total net annual Fund's operating expenses for the Fund's Class A, Class C, Class R, and Institutional Class shares are 0.95%. The Manager's and Distributor's waivers and/or reimbursements may be discontinued at any time because they are voluntary.

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 that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (Delaware Large Cap Core Fund) (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	854	1,429	2,029	3,640
Class C	470	1,126	1,902	3,932
Class R	331	1,010	1,712	3,576
Institutional Class	271	832	1,420	3,012

Expense Example, No Redemption (Delaware Large Cap Core Fund) (USD $)	1 Year	3 Years	5 Years	10 Years
Class C	370	1,126	1,902	3,932

Portfolio turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 41% of the average value of its portfolio.

What are the Fund's principal investment strategies?

The Fund's investment manager, Delaware Management Company (Manager), will invest the Fund's assets primarily in common stocks of large companies that the Manager believes have a combination of attractive valuations, growth prospects, and strong cash flows. Under normal circumstances, the Fund will invest at least 80% of its net assets in securities of large-capitalization companies (80% policy). The Fund currently defines large-capitalization companies as those that, at the time of investment, have market capitalizations within the range of market capitalizations of companies in the S&P 500® Index. While the market capitalization of companies in the S&P 500 Index ranged from approximately $1.3 billion to $547 billion as of June 30, 2012, the Fund will normally invest in common stock of companies with market capitalizations of at least $2 billion at the time of purchase. The Fund's 80% policy can be changed without shareholder approval. However, shareholders would be given at least 60 days' notice prior to any change.

What are the principal risks of investing in the Fund?

Investing in any mutual fund involves the risk that you may lose part or all of the money you invest. Over time, the value of your investment in the Fund will increase and decrease according to changes in the value of the securities in the Fund's portfolio. Principal risks include:

Investments not guaranteed by the Manager or its affiliates — Investments in the Fund are not and will not be deposits with or liabilities of Macquarie Bank Limited ABN 46 008 583 542 and its holding companies, including their subsidiaries or related companies (Macquarie Group), and are subject to investment risk, including possible delays in repayment and loss of income and capital invested. No Macquarie Group company guarantees or will guarantee the performance of the Fund, the repayment of capital from the Fund, or any particular rate of return.

Market risk — The risk that all or a majority of the securities in a certain market — such as the stock or bond market — will decline in value because of factors such as adverse political or economic conditions, future expectations, investor confidence, or heavy institutional selling.

Foreign risk — The risk that foreign securities (particularly in emerging markets) may be adversely affected by political instability; changes in currency exchange rates; inefficient markets and higher transaction costs; foreign economic conditions; or inadequate or different regulatory and accounting standards.

Futures and options risk — The possibility that a fund may experience a loss if it employs an options or futures strategy related to a security or a market index and that security or index moves in the opposite direction from what the Manager anticipated. Futures and options also involve additional expenses (such as the payment of premiums), which could reduce any benefit or increase any loss that a fund gains from using the strategy.

Counterparty risk — The risk that a counterparty to a derivative contract (such as a futures or options contract) or a repurchase agreement may fail to perform its obligations under the contract or agreement due to financial difficulties (such as a bankruptcy or reorganization).

Liquidity risk — The possibility that securities cannot be readily sold within seven days at approximately the price at which a fund has valued them.

Government and regulatory risk — The risk that governments or regulatory authorities have, from time to time, taken or considered actions that could adversely affect various sectors of the securities markets.

How has Delaware Large Cap Core Fund performed?

The bar chart and table below provide some indication of the risks of investing in the Fund by showing changes in the Fund's performance from year to year and by showing how the Fund's average annual returns for 1-year, 5-year, and lifetime periods compare with those of a broad measure of market performance. The Fund's past performance (before and after taxes) is not necessarily an indication of how it will perform in the future. The returns reflect expense caps in effect during these periods. The returns would be lower without the expense caps. Applicable sales charges are reflected in the average annual total return table below.

After-tax performance is presented only for Class A shares of the Fund. The after-tax returns for other Fund classes may vary. Actual after-tax returns depend on the investor's individual tax situation and may differ from the returns shown. After-tax returns are not relevant for shares held in tax-deferred investment vehicles such as employer-sponsored 401(k) plans and individual retirement accounts (IRAs). The after-tax returns shown are calculated using the highest individual federal marginal income tax rates in effect during the periods presented and do not reflect the impact of state and local taxes.

[1] Class C shares redeemed within one year of purchase are subject to a 1.00% contingent deferred sales charge (CDSC).
