Delaware Diversified Income Fund | ||||||||||||||||||||||||||||||||||||||||||||||||||||||
What is the Funds investment objective? | ||||||||||||||||||||||||||||||||||||||||||||||||||||||
Delaware Diversified Income Fund seeks maximum long-term total return, consistent with reasonable risk.
| ||||||||||||||||||||||||||||||||||||||||||||||||||||||
What are the Funds fees and expenses? | ||||||||||||||||||||||||||||||||||||||||||||||||||||||
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 $100,000 in Delaware FundsSM by Macquarie. More information about these and other discounts is available from your financial intermediary, in the Funds Prospectus under the section entitled About your account, and in the Funds statement of additional information (SAI) under the section entitled Purchasing Shares.

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

| ||||||||||||||||||||||||||||||||||||||||||||||||||||||
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 the annual fund operating expenses or in the example, affect the Funds performance. During the most recent fiscal year, the Funds portfolio turnover rate was 125% of the average value of its portfolio. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||
What are the Funds principal investment strategies? | ||||||||||||||||||||||||||||||||||||||||||||||||||||||
The Fund allocates its investments principally among the following four sectors of the fixed income securities markets: the US investment grade sector, the US high yield sector, the international developed markets sector, and the emerging markets sector. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in fixed income securities (80% policy). The Funds investment manager, Delaware Management Company (Manager), will determine how much of the Funds assets to allocate to each of the four sectors, based on its evaluation of economic and market conditions, and its assessment of the returns and potential for appreciation that can be achieved from investments in each of the four sectors. The Manager will periodically reallocate the Funds assets as deemed necessary. Under normal circumstances, between 5% and 35% of the Funds net assets will be allocated to the US high yield sector. The Funds investments in emerging markets will, in the aggregate, be limited to no more than 20% of the Funds net assets. The Fund will limit its investments in foreign securities to between 5% and 40% of its net assets and will seek to hedge its foreign currency exposure, which will be limited to 20% of the Funds net assets, by entering into forward foreign currency contracts. The Fund may hold a substantial portion of its assets in cash or short-term fixed income obligations in unusual market conditions to meet redemption requests, for temporary defensive purposes, and pending investment. The Fund may invest in mortgage-backed securities and other asset-backed securities. The Fund may also use a wide range of derivatives instruments, typically including options, futures contracts, options on futures contracts, and 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; interest rate swaps to neutralize the impact of interest rate changes; credit default swaps to hedge against a credit event, to gain exposure to certain securities or markets, or to enhance total return; and index swaps to enhance return or to effect diversification. The Fund will not use derivatives for reasons inconsistent with its investment objective. The Funds 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. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||
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 Funds portfolio. The Funds 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. Loans and other indebtedness risk The risk that the fund will not receive payment of principal, interest, and other amounts due in connection with these investments and will depend primarily on the financial condition of the borrower and the lending institution. A funds ability to sell its loans or to realize their full value upon sale may also be impaired due to the lack of an active trading market, irregular trading activity, wide bid/ask spreads, contractual restrictions, and extended trade settlement periods. In addition, certain loans in which a fund invests may not be considered securities. A fund therefore may not be able to rely upon the anti-fraud provisions of the federal securities laws with respect to these investments. Prepayment risk The risk that the principal on a bond that is held by a fund will be prepaid prior to maturity at a time when interest rates are lower than what that bond was paying. A fund may then have to reinvest that money at a lower interest rate. Mortgage-backed and asset-backed securities risk The risk that the principal on mortgage-backed or asset-backed securities may be prepaid at any time, which will reduce the yield and market value. 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. 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.
Liquidity risk The possibility that securities cannot be readily sold within seven calendar days at approximately the price at which a fund has valued them. Valuation risk The risk that a less liquid secondary market may make it more difficult for a fund to obtain precise valuations of certain securities in its portfolio. 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.

What are the Funds principal investment strategies? | ||||||||||||||||||||||||||||||||||||||||||||||||||||||
Under normal circumstances, the Fund will invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in US investments (80% policy). The Fund invests primarily in common stocks of companies that its portfolio managers believe have long-term capital appreciation potential and are expected to grow faster than the US economy. Using a bottom-up approach, the portfolio managers seek to select securities they believe have large end-market potential, dominant business models, and strong free cash flow generation that are attractively priced compared to the intrinsic value of the securities. The portfolio managers also consider a companys operational efficiencies, managements plans for capital allocation, and the companys shareholder orientation. All of these factors give the portfolio managers insight into the outlook for a company, helping identify companies poised for sustainable free cash flow growth. The portfolio managers believe that sustainable free cash flow growth, if it occurs, may result in price appreciation for the companys stock. The portfolio managers may sell a security if they no longer believe that the security is likely to contribute to meeting the investment objective of the Fund or if there are other opportunities that appear more attractive. The Funds 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. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||

What are the Funds principal investment strategies? | ||||||||||||||||||||||||||||||||||||||||||||||||||||||
Under normal circumstances, the Fund will invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in US and non-US real estate and real estaterelated issuers (80% policy). The Fund generally considers an issuer to be a real estate or real estaterelated issuer if at least 50% of its revenue is from real estate or if it has at least 50% of its assets in real estate. These companies include, among others, real estate investment trusts (REITs) and similar REIT-like entities domiciled outside the US, as well as other companies whose products and services are related to the real estate industry, such as manufacturers and distributors of building supplies and financial institutions that issue or service mortgages. The Fund invests primarily in REITs and other equity securities. REITs are pooled investment vehicles that invest primarily in income-producing real estate or real estaterelated loans or interests. The Fund may invest in companies across all market capitalizations and may invest its assets in securities of companies located in emerging market countries. Under normal circumstances, the Fund will invest at least 40% of its total assets in securities of non-US issuers, unless market conditions are not deemed favorable by the Manager, in which case the Fund would invest at least 30% of its net assets in securities of non-US issuers. The Fund may purchase or sell foreign currencies and/or engage in forward foreign currency contracts in order to facilitate or expedite settlement of portfolio transactions and to minimize currency fluctuations. The Fund may also enter into forward contracts to lock in the price of a security it has agreed to purchase or sell, in terms of US dollars or other currencies in which the transaction will be consummated. The Funds 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. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||
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 Funds portfolio. The Funds 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. 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. 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. 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). 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. Nondiversification risk A nondiversified fund has the flexibility to invest as much as 50% of its assets in as few as two issuers with no single issuer accounting for more than 25% of the fund. The remaining 50% of its assets must be diversified so that no more than 5% of its assets are invested in the securities of a single issuer. Because a nondiversified fund may invest its assets in fewer issuers, the value of its shares may increase or decrease more rapidly than if it were fully diversified. 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 period of historically low interest rates. Liquidity risk The possibility that securities 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 Fund is the successor to The Global Real Estate Securities Portfolio, formerly a series of the Delaware Pooled® Trust, pursuant to the reorganization (Reorganization) of The Global Real Estate Securities Portfolio, which occurred on Sept. 28, 2012. Prior to the Reorganization, the Fund had no investment operations. Accordingly, the performance information shown below for periods prior to Sept. 28, 2012 is historical information for The Global Real Estate Securities Portfolio, which has been adjusted to reflect the Funds applicable sales charges and 12b-1 fees, but not certain other expenses. Because the Funds fees and expenses are higher than those of The Global Real Estate Securities Portfolio, the Funds performance would have been lower than that shown below for The Global Real Estate Securities Portfolio.

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 Funds performance. During the most recent fiscal year, the Funds portfolio turnover rate was 125% 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 Funds 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 Funds principal investment strategies? | ||||||
Strategy Narrative | rr_StrategyNarrativeTextBlock | The Fund allocates its investments principally among the following four sectors of the fixed income securities markets: the US investment grade sector, the US high yield sector, the international developed markets sector, and the emerging markets sector. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in fixed income securities (80% policy). The Funds investment manager, Delaware Management Company (Manager), will determine how much of the Funds assets to allocate to each of the four sectors, based on its evaluation of economic and market conditions, and its assessment of the returns and potential for appreciation that can be achieved from investments in each of the four sectors. The Manager will periodically reallocate the Funds assets as deemed necessary. Under normal circumstances, between 5% and 35% of the Funds net assets will be allocated to the US high yield sector. The Funds investments in emerging markets will, in the aggregate, be limited to no more than 20% of the Funds net assets. The Fund will limit its investments in foreign securities to between 5% and 40% of its net assets and will seek to hedge its foreign currency exposure, which will be limited to 20% of the Funds net assets, by entering into forward foreign currency contracts. The Fund may hold a substantial portion of its assets in cash or short-term fixed income obligations in unusual market conditions to meet redemption requests, for temporary defensive purposes, and pending investment. The Fund may invest in mortgage-backed securities and other asset-backed securities. The Fund may also use a wide range of derivatives instruments, typically including options, futures contracts, options on futures contracts, and 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; interest rate swaps to neutralize the impact of interest rate changes; credit default swaps to hedge against a credit event, to gain exposure to certain securities or markets, or to enhance total return; and index swaps to enhance return or to effect diversification. The Fund will not use derivatives for reasons inconsistent with its investment objective. The Funds 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 | 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 Funds portfolio. The Funds 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. Loans and other indebtedness risk The risk that the fund will not receive payment of principal, interest, and other amounts due in connection with these investments and will depend primarily on the financial condition of the borrower and the lending institution. A funds ability to sell its loans or to realize their full value upon sale may also be impaired due to the lack of an active trading market, irregular trading activity, wide bid/ask spreads, contractual restrictions, and extended trade settlement periods. In addition, certain loans in which a fund invests may not be considered securities. A fund therefore may not be able to rely upon the anti-fraud provisions of the federal securities laws with respect to these investments. Prepayment risk The risk that the principal on a bond that is held by a fund will be prepaid prior to maturity at a time when interest rates are lower than what that bond was paying. A fund may then have to reinvest that money at a lower interest rate. Mortgage-backed and asset-backed securities risk The risk that the principal on mortgage-backed or asset-backed securities may be prepaid at any time, which will reduce the yield and market value. 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. 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.
Liquidity risk The possibility that securities cannot be readily sold within seven calendar days at approximately the price at which a fund has valued them. Valuation risk The risk that a less liquid secondary market may make it more difficult for a fund to obtain precise valuations of certain securities in its portfolio. 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.

Strategy | rr_StrategyHeading | What are the Funds principal investment strategies? | ||||||
Strategy Narrative | rr_StrategyNarrativeTextBlock | Under normal circumstances, the Fund will invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in US investments (80% policy). The Fund invests primarily in common stocks of companies that its portfolio managers believe have long-term capital appreciation potential and are expected to grow faster than the US economy. Using a bottom-up approach, the portfolio managers seek to select securities they believe have large end-market potential, dominant business models, and strong free cash flow generation that are attractively priced compared to the intrinsic value of the securities. The portfolio managers also consider a companys operational efficiencies, managements plans for capital allocation, and the companys shareholder orientation. All of these factors give the portfolio managers insight into the outlook for a company, helping identify companies poised for sustainable free cash flow growth. The portfolio managers believe that sustainable free cash flow growth, if it occurs, may result in price appreciation for the companys stock. The portfolio managers may sell a security if they no longer believe that the security is likely to contribute to meeting the investment objective of the Fund or if there are other opportunities that appear more attractive. The Funds 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. |

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 Funds performance. During the most recent fiscal year, the Funds portfolio turnover rate was 217% 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 reflects the Managers expense 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:

Strategy | rr_StrategyHeading | What are the Funds principal investment strategies? | ||||||
Strategy Narrative | rr_StrategyNarrativeTextBlock | Under normal circumstances, the Fund will invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in US and non-US real estate and real estaterelated issuers (80% policy). The Fund generally considers an issuer to be a real estate or real estaterelated issuer if at least 50% of its revenue is from real estate or if it has at least 50% of its assets in real estate. These companies include, among others, real estate investment trusts (REITs) and similar REIT-like entities domiciled outside the US, as well as other companies whose products and services are related to the real estate industry, such as manufacturers and distributors of building supplies and financial institutions that issue or service mortgages. The Fund invests primarily in REITs and other equity securities. REITs are pooled investment vehicles that invest primarily in income-producing real estate or real estaterelated loans or interests. The Fund may invest in companies across all market capitalizations and may invest its assets in securities of companies located in emerging market countries. Under normal circumstances, the Fund will invest at least 40% of its total assets in securities of non-US issuers, unless market conditions are not deemed favorable by the Manager, in which case the Fund would invest at least 30% of its net assets in securities of non-US issuers. The Fund may purchase or sell foreign currencies and/or engage in forward foreign currency contracts in order to facilitate or expedite settlement of portfolio transactions and to minimize currency fluctuations. The Fund may also enter into forward contracts to lock in the price of a security it has agreed to purchase or sell, in terms of US dollars or other currencies in which the transaction will be consummated. The Funds 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 | Under normal circumstances, the Fund will invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in US and non-US real estate and real estaterelated issuers (80% policy). | ||||||
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 Funds portfolio. The Funds 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. 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. 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. 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). 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. Nondiversification risk A nondiversified fund has the flexibility to invest as much as 50% of its assets in as few as two issuers with no single issuer accounting for more than 25% of the fund. The remaining 50% of its assets must be diversified so that no more than 5% of its assets are invested in the securities of a single issuer. Because a nondiversified fund may invest its assets in fewer issuers, the value of its shares may increase or decrease more rapidly than if it were fully diversified. 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 period of historically low interest rates. Liquidity risk The possibility that securities 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 Manager is an indirect wholly owned subsidiary of Macquarie Group Limited (MGL). Other than Macquarie Bank Limited (MBL), a subsidiary of MGL and an affiliate of the Manager, none of the entities noted are authorized deposit-taking institutions for the purposes of the Banking Act 1959 (Commonwealth of Australia).

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 Funds portfolio. | ||||||
Risk Nondiversified Status | rr_RiskNondiversifiedStatus | Nondiversification risk A nondiversified fund has the flexibility to invest as much as 50% of its assets in as few as two issuers with no single issuer accounting for more than 25% of the fund. The remaining 50% of its assets must be diversified so that no more than 5% of its assets are invested in the securities of a single issuer.

Bar Chart and Performance Table | rr_BarChartAndPerformanceTableHeading | How has Delaware Global Real Estate Opportunities Fund performed? | ||||||
Performance Narrative | rr_PerformanceNarrativeTextBlock | The bar chart and table below provide some indication of the risks of investing in the Fund by showing changes in the Funds performance from year to year and by showing how the Funds 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 Funds 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. The returns would be lower without the expense caps. You may obtain the Funds most recently available month-end performance by calling 800 523-1918 or by visiting our website at delawarefunds.com/performance.
The Fund is the successor to The Global Real Estate Securities Portfolio, formerly a series of the Delaware Pooled® Trust, pursuant to the reorganization (Reorganization) of The Global Real Estate Securities Portfolio, which occurred on Sept. 28, 2012. Prior to the Reorganization, the Fund had no investment operations. Accordingly, the performance information shown below for periods prior to Sept. 28, 2012 is historical information for The Global Real Estate Securities Portfolio, which has been adjusted to reflect the Funds applicable sales charges and 12b-1 fees, but not certain other expenses. Because the Funds fees and expenses are higher than those of The Global Real Estate Securities Portfolio, the Funds performance would have been lower than that shown below for The Global Real Estate Securities Portfolio.
