The table below 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 Funds® by Macquarie. More information about these and other discounts is available from your financial intermediary, in the Fund’s Prospectus under the section entitled “About your account,” and in the Fund’s statement of additional information (SAI) under the section entitled “Purchasing Shares.”

Portfolio Turnover rr_PortfolioTurnoverTextBlock 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 the 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 91% of the average value of its portfolio.

Expense Example Narrative rr_ExpenseExampleNarrativeTextBlock

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. In addition, the example shows expenses for Class C shares, assuming those shares were not redeemed 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:

 
Strategy rr_StrategyHeading What are the Fund’s principal investment strategies?
Strategy Narrative rr_StrategyNarrativeTextBlock

The Fund invests primarily in income-generating securities (debt and equity), which may include equity securities of large, well-established companies, and debt securities, including high yield, high-risk corporate bonds, investment grade fixed income securities, and US government securities.

Under normal circumstances, at least 50% of the Fund’s total assets will be invested in income-generating equity securities, including real estate investment trusts (REITs). In making investments in income-generating equity securities, the Fund may invest an unlimited portion of its total assets in convertible securities without regard to credit quality. While debt securities may comprise up to 50% of the Fund’s total assets, no more than 45% of the Fund’s total assets will be invested in high yield, high-risk debt securities. No more than 25% of the Fund’s total assets will be invested in any one industry sector nor, as to 75% of the Fund’s total assets, will more than 5% be invested in securities of any one issuer. The Fund may invest up to 30% of its total assets in foreign equity and debt securities. The Fund will not, however, invest more than 10% of its total assets in securities of issuers principally located or principally operating in markets of emerging countries.

Within the percentage guidelines noted above, the Fund’s investment manager, Delaware Management Company (Manager), will determine the proportion of the Fund’s assets that will be allocated to income-generating equity securities and equity equivalents and to debt securities, based on its analysis of economic and market conditions and its assessment of the income and potential for appreciation that can be achieved from investments in such asset classes. It is expected that the proportion of the Fund’s total assets invested in income-generating equity securities and equity equivalent securities will vary from 50% to 100% of the Fund’s total assets. The proportion of the Fund’s total assets in debt securities will correspondingly vary from 0% to 50% of the Fund’s total assets.

In addition, the Manager may seek investment advice and recommendations from its affiliates: Macquarie Investment Management Europe Limited (MIMEL), Macquarie Investment Management Austria Kapitalanlage AG (MIMAK), and Macquarie Investment Management Global Limited (MIMGL). The Manager may also permit MIMEL, MIMAK, MIMGL, and Macquarie Funds Management Hong Kong Limited (MFMHKL) (together, the “Affiliated Sub-Advisors”) to execute Fund security trades on behalf of the Manager.  The Manager may also permit MIMEL, MIMAK, and MIMGL to exercise investment discretion for securities in certain markets where the Manager believes it will be beneficial to utilize an Affiliated Sub-Advisor’s specialized market knowledge, and the Manager may also seek quantitative support from MIMGL.

The Fund may use a wide range of derivative instruments, typically including forward foreign currency contracts, options, futures contracts, options on futures contracts, and credit default swaps. The Fund will use derivatives for both hedging and nonhedging purposes. For example, the Fund may invest in: futures and options to manage duration and for defensive purposes, such as to protect gains or hedge against potential losses in the portfolio without actually selling a security, or to stay fully invested; forward foreign currency contracts to manage foreign currency exposure; and credit default swaps to hedge against a credit event, to gain exposure to certain securities or markets, or to enhance total return.

Investment in the Fund does not in any way provide an indication of future performance or a guarantee of positive returns.

Risk rr_RiskHeading What are the principal risks of investing in the Fund?
Risk Narrative rr_RiskNarrativeTextBlock

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. An investment in the Fund may not be appropriate for all investors. The Fund’s principal risks include:

 

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.

Credit risk — The risk that an issuer of a debt security, including a governmental issuer or an entity that insures a bond, may be unable to make interest payments and/or repay principal in a timely manner.

High yield (junk bond) risk — The risk that high yield securities, commonly known as “junk bonds,” are subject to reduced creditworthiness of issuers, increased risk of default, and a more limited and less liquid secondary market. High yield securities may also be subject to greater price volatility and risk of loss of income and principal than are higher-rated securities. High yield bonds are sometimes issued by municipalities that have less financial strength and therefore have less ability to make projected debt payments on the bonds.

Interest rate risk — The risk that the prices of bonds and other fixed income securities will increase as interest rates fall and decrease as interest rates rise. Interest rate changes are influenced by a number of factors, such as government policy, monetary policy, inflation expectations, and the supply and demand of bonds. Bonds and other fixed income securities with longer maturities or duration generally are more sensitive to interest rate changes. A fund may be subject to a greater risk of rising interest rates due to the current period of historically low interest rates.

Real estate industry risk — This risk includes, among others: possible declines in the value of real estate; risks related to general and local economic conditions; possible lack of availability of mortgage funds; overbuilding; extended vacancies of properties; increases in competition, property taxes, and operating expenses; changes in zoning laws; costs resulting from the cleanup of, and liability to third parties resulting from, environmental problems; casualty for condemnation losses; uninsured damages from floods, earthquakes, or other natural disasters; limitations on and variations in rents; and changes in interest rates.

Derivatives risk — Derivatives contracts, such as futures, forward foreign currency contracts, options, and swaps, may involve additional expenses (such as the payment of premiums) and are subject to significant loss if a security, index, reference rate, or other asset or market factor to which a derivatives contract is associated, moves in the opposite direction from what the portfolio manager anticipated. When used for hedging, the change in value of the derivatives instrument may also not correlate specifically with the currency, rate, or other risk being hedged, in which case a fund may not realize the intended benefits. Derivatives contracts are also subject to the risk that the counterparty may fail to perform its obligations under the contract due to, among other reasons, financial difficulties (such as a bankruptcy or reorganization).

Leveraging risk — The risk that certain fund transactions, such as reverse repurchase agreements, short sales, loans of portfolio securities, and the use of when-issued, delayed delivery or forward commitment transactions, or derivatives instruments, may give rise to leverage, causing a fund to be more volatile than if it had not been leveraged, which may result in increased losses to the fund.

 

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, the imposition of economic or trade sanctions, or inadequate or different regulatory and accounting standards.

Government and regulatory risk — The risk that governments or regulatory authorities may take actions that could adversely affect various sectors of the securities markets and affect fund performance.

LIBOR risk — The risk that potential changes related to the use of the London Interbank Offered Rate (LIBOR) could have adverse impacts on financial instruments which reference LIBOR. While some instruments may contemplate a scenario where LIBOR is no longer available by providing for an alternative rate setting methodology, not all instruments have such fallback provisions and the effectiveness of replacement rates is uncertain. The potential abandonment of LIBOR could affect the value and liquidity of instruments which reference LIBOR, especially those that do not have fallback provisions.

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

Active management and selection risk — The risk that the securities selected by a fund’s management will underperform the markets, the relevant indices, or the securities selected by other funds with similar investment objectives and investment strategies. The securities and sectors selected may vary from the securities and sectors included in the relevant index.

Strategy rr_StrategyHeading What are the Fund’s principal investment strategies?
Strategy Narrative rr_StrategyNarrativeTextBlock

The Fund invests primarily in stocks of small companies that its investment manager, Delaware Management Company (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, plus the amount of any borrowings for investment purposes, will be in investments of small-capitalization companies (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 Manager may permit its affiliates, Macquarie Investment Management Global Limited (MIMGL) and Macquarie Funds Management Hong Kong Limited (MFMHKL), to execute Fund security trades on behalf of the Manager. The Manager may also seek quantitative support from MIMGL.

The Fund’s 80% policy is nonfundamental and may be changed without shareholder approval. Fund shareholders would be given at least 60 days’ notice prior to any such change.

Risk Narrative rr_RiskNarrativeTextBlock

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. An investment in the Fund may not be appropriate for all investors. The Fund’s principal risks include:

 

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

 

Company size risk — The risk that investments in small- and/or 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. A fund may be subject to a greater risk of rising interest rates due to the current period of historically low interest rates.

 

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

Government and regulatory risk — The risk that governments or regulatory authorities may take actions that could adversely affect various sectors of the securities markets and affect fund performance.

Active management and selection risk — The risk that the securities selected by a fund’s management will underperform the markets, the relevant indices, or the securities selected by other funds with similar investment objectives and investment strategies. The securities and sectors selected may vary from the securities and sectors included in the relevant index.

The table below 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 Funds® by Macquarie. More information about these and other discounts is available from your financial intermediary, in the Fund’s Prospectus under the section entitled “About your account,” and in the Fund’s statement of additional information (SAI) under the section entitled “Purchasing Shares.”

Portfolio Turnover Heading rr_PortfolioTurnoverHeading Portfolio turnover
Portfolio Turnover rr_PortfolioTurnoverTextBlock 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 the 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 18% of the average value of its portfolio.

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. In addition, the example shows expenses for Class C shares, assuming those shares were not redeemed 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:

 
Strategy rr_StrategyHeading What are the Fund’s principal investment strategies?
Strategy Narrative rr_StrategyNarrativeTextBlock

The Fund invests primarily in investments of small companies whose stock prices, in the portfolio managers’ opinion, appear low relative to their underlying value or future potential. Among other factors, the Fund’s investment manager, Delaware Management Company (Manager), considers the financial strength of a company, its management, the prospects for its industry, and any anticipated changes within the company that might suggest a more favorable outlook going forward. The Manager focuses on free cash flow in its individual stock selection, seeking companies that it believes have a sustainable ability to buy back shares, lower debt, and/or increase or initiate dividends. Under normal circumstances, at least 80% of the Fund’s net assets, plus the amount of any borrowings for investment purposes, will be in investments of small-capitalization companies (80% policy). The Fund considers small-capitalization companies to be companies with a market capitalization generally less than 3.5 times the dollar-weighted, median market capitalization of the Russell 2000® Index at the time of purchase. The Fund may invest up to 15% of its net assets in real estate investment trusts (REITs).

The Manager may permit its affiliates, Macquarie Investment Management Global Limited (MIMGL) and Macquarie Funds Management Hong Kong Limited (MFMHKL), to execute Fund security trades on behalf of the Manager. The Manager may also seek quantitative support from MIMGL.

The Fund’s 80% policy is nonfundamental and may be changed without shareholder approval. Fund shareholders would be given at least 60 days’ notice prior to any such change.

 
Strategy Portfolio Concentration rr_StrategyPortfolioConcentration The Fund invests primarily in investments of small companies whose stock prices, in the portfolio managers’ opinion, appear low relative to their underlying value or future potential.
Risk rr_RiskHeading What are the principal risks of investing in the Fund?
Risk Narrative rr_RiskNarrativeTextBlock

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. An investment in the Fund may not be appropriate for all investors. The Fund’s principal risks include:

 

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

 

Company size risk — The risk that investments in small- and/or 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. A fund may be subject to a greater risk of rising interest rates due to the current period of historically low 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, the imposition of economic or trade sanctions, or inadequate or different regulatory and accounting standards.

Real estate industry risk — This risk includes, among others: possible declines in the value of real estate; risks related to general and local economic conditions; possible lack of availability of mortgage funds; overbuilding; extended vacancies of properties; increases in competition, property taxes, and operating expenses; changes in zoning laws; costs resulting from the cleanup of, and liability to third parties resulting from, environmental problems; casualty for condemnation losses; uninsured damages from floods, earthquakes, or other natural disasters; limitations on and variations in rents; and changes in interest rates.

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

Government and regulatory risk — The risk that governments or regulatory authorities may take actions that could adversely affect various sectors of the securities markets and affect fund performance.

Active management and selection risk — The risk that the securities selected by a fund’s management will underperform the markets, the relevant indices, or the securities selected by other funds with similar investment objectives and investment strategies. The securities and sectors selected may vary from the securities and sectors included in the relevant index.

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 total returns for the 1-, 5-, and 10-year or 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 any expense caps in effect during these periods.
