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:

Expense Example (Delaware Small Cap Core Fund) (Retail) (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	709	1,003	1,318	2,206
Class C	318	673	1,154	2,483
Class R	168	541	940	2,054

Expense Example, No Redemption (Delaware Small Cap Core Fund) (USD $)	1 Year	3 Years	5 Years	10 Years
Class C (Retail)	218	673	1,154	2,483

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 42% of the average value of its portfolio.

What are the Fund's principal investment strategies?

The Fund invests primarily in stocks of small companies that the Manager believes have a combination of attractive valuations, growth prospects, and strong cash flows. Under normal circumstances, at least 80% of the Fund's net assets will be in investments of small-capitalization companies (the 80% policy). The Fund considers small-capitalization companies to be companies within the market capitalization range of the Russell 2000® Index at the time of purchase. The Fund's 80% policy may be changed without shareholder approval. However, shareholders will be given notice at least 60 days 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.

Industry risk — The risk that the value of securities in a particular industry (such as financial services or manufacturing) will decline because of changing expectations for the performance of that industry.

Small company risk — The risk that prices of small- and medium-sized companies may be more volatile than those of larger companies because of limited financial resources or dependence on narrow product lines.

Interest rate risk — The risk that securities will decrease in value if interest rates rise. The risk is generally associated with bonds; however, because small- and medium-sized companies and companies in the real estate sector often borrow money to finance their operations, they may be adversely affected by rising interest rates.

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.

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

Counterparty risk — The risk that a counterparty to a derivative contract (such as a swap, 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).

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 Small 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 the 1-, 5-, and 10-year or lifetime periods compare with those of a broad measure of market performance. Prior to August 1, 2005, the Fund had not engaged in a broad distribution effort of its shares and had been subject to limited redemption requests. 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. You may obtain the Fund's most recently available month-end performance by calling 800 523-1918 or by visiting our website at www.delawareinvestments.com/performance.

On November 1, 2004, the Fund's strategy and management changed. The new management team retained the Fund's small-cap focus by investing primarily in stocks of small companies that are believed to have a combination of attractive valuations, growth prospects, and strong cash flows.

Year-by-year total return (Class A)

During the periods illustrated in this bar chart, Class A's highest quarterly return was 20.77% for the quarter ended June 30, 2009 and its lowest quarterly return was -26.16% for the quarter ended December 31, 2008. The maximum Class A sales charge of 5.75%, which is normally deducted when you purchase shares, is not reflected in the highest/lowest quarterly returns or in the bar chart. If this sales charge were included, the returns would be less than those shown. The average annual returns in the table below do include the sales charge.

Average annual total returns for periods ended December 31, 2011

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.

In addition, the Fund's distributor, Delaware Distributors, L.P.
