Investment Strategy, Heading	rr_StrategyHeading	INVESTMENTS, RISKS AND PERFORMANCE
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	PRINCIPAL INVESTMENT STRATEGIES The Fund, under normal market conditions invests at least 80% of its net assets in "real return" assets consisting of (i) inflation-protected debt securities, (ii) real estate-related securities, and (iii) commodity/natural resource-related securities. The Fund considers a company to be a real estate company if at least 50% of its assets, gross income or net profits is derived from (i) development, ownership, leasing, financing, construction, management or sale of real estate or (ii) products and services that are related to the real estate industry, such as manufacturers and distributors of building supplies and financial institutions which issue or service mortgages. The Fund will invest in real estate companies, such as real estate investment trusts ("REITs") that own property and mortgage REITs that make construction and development loans or invest in mortgage pools, or companies whose products and services relate to the real estate industry. The Fund may invest its assets in equity, debt or convertible securities of companies whose products and services are related to the real estate industry or in securities whose products and services are related to the real estate industry. In order to gain exposure to the commodities markets without investing directly in physical commodities, the Fund invests in investment companies, exchange traded funds ("ETFs"), structured notes, futures contracts, forward currency exchange contracts, currency futures and swap agreements. The Fund's anticipated use structured notes, futures contracts, forward currency exchange contracts, currency futures and swap agreements is expected to be frequent and may at times be substantial. The Fund may also invest in common stocks, preferred stocks and convertible securities of issuers in commodity-related industries to gain exposure to the commodities markets. The investment adviser, Rodney Square Management Corporation ("RSMC"), determines the Fund's asset allocation among the "real return" assets. RSMC anticipates allocating approximately 20%-80% to inflation-protected debt securities, 0%-60% to real estate-related securities and 0%-40% to commodity/natural resource-related securities. The allocations and/or actual holdings will vary from time to time. The Fund utilizes a multi-manager strategy in which RSMC allocates the Fund's assets among a number of sub-advisers, or invests directly (up to 60% of the Fund's assets) in ETFs. Subject to the supervision of RSMC, each sub-adviser acts independently from the others and utilizes its own distinct investment style in buying and selling securities within the constraints of the Fund's investment objective, strategies and restrictions. The Fund may invest up to 55% of its assets in foreign securities.
Risk, Heading	rr_RiskHeading	PRINCIPAL RISKS OF INVESTING IN THE FUND
Risk, Narrative	rr_RiskNarrativeTextBlock	Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment may fluctuate significantly from day-to-day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. An investment in the Fund is not a deposit of Wilmington Trust Company or any of its affiliates and is not insured or guaranteed by Federal Deposit Insurance Corporation or any other governmental agency. There is no assurance that the Fund will achieve its investment objective. The Fund is subject to the principal risks described below. o ALLOCATION RISK: The risk that the investment adviser will make less than optimal or poor asset allocation decisions to the sub-advisers of the Fund. o COMMODITY/NATURAL RESOURCE-RELATED SECURITIES RISK: The risk that investing in commodity-related securities investments may subject the Fund to greater volatility than investments in other kinds of securities. In addition to overall market movements, commodity-related securities may be adversely impacted by commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as weather, disease, embargoes, acts of war or terrorism, or political and regulatory developments. o DEBT SECURITY RISK: Fixed income securities are subject to credit risk, interest rate risk and prepayment risk. o EMERGING MARKETS RISK: The risk that markets of emerging market countries are less developed and less liquid, subject to greater price volatility and generally subject to increased economic, political, regulatory and other uncertainties than more developed markets. o FOREIGN SECURITIES RISK: The risk that investing in foreign (non-U.S.) securities may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies, due to less liquid markets, and adverse economic, political, diplomatic, financial, and regulatory factors. Foreign governments also may impose limits on investment and repatriation and impose taxes. Any of these events could cause the value of the Fund's investments to decline. o FORWARD CURRENCY EXCHANGE CONTRACT RISK: A forward foreign currency exchange contract is an agreement to buy or sell a specific currency at a future date and at a price set at the time of the contract. Forward foreign currency exchange contracts may reduce the risk of loss from a change in value of a currency, but they also limit any potential gains, do not protect against fluctuations in the value of the underlying position and are subject to counterparty risk. o FUTURES CONTRACTS RISK: The risks associated with futures include: the potential inability to terminate or sell a position, the lack of a liquid secondary market for the Fund's position and the risk that the counterparty to the transaction will not meet its obligations. o INFLATION-INDEXED DEBT SECURITIES RISK: Inflation-indexed debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). There can be no assurance that the inflation index used will accurately measure the real rate of inflation in the prices of goods and services. The performance of any securities that are indexed to non-U. S. rates of inflation may be higher or lower than those indexed to U. S. inflation rates. o INVESTMENT COMPANY RISK: As a shareholder in an investment company, the Fund bears its pro-rata portion of the investment company's expenses, including advisory fees, in addition to its own expenses. o LEVERAGE RISK: The risk associated with securities transactions or practices that multiply small market movements into larger changes in value. o LIQUIDITY RISK: The risk that certain securities may be difficult or impossible to sell at the time and the price that the seller would like. o MARKET RISK: The risk that the market value of a security may fluctuate, sometimes rapidly and unpredictably. o MULTI-MANAGER RISK: The investment styles employed by sub-advisers may not be complementary. The multi-manager approach could result in a high level of portfolio turnover, resulting in higher brokerage expenses and increased tax liability from the Fund's realization of capital gains. o RISKS OF REAL ESTATE-RELATED SECURITIES: Property values may fall due to increasing vacancies or declining rents resulting from economic, legal, cultural or technological developments. The price of a real estate company's shares may drop because of the failure of the real estate company borrowers to pay their loans and poor management. REITs involve additional risk factors including poor performance by a REIT's manager, changes to the tax laws, and failure by the REIT to qualify for tax- free distribution of income or exemption under the Investment Company Act of 1940 (the "1940 Act"). Since REITs have expenses of their own, the Fund will bear a proportionate share of these expenses in addition to the expenses of the Fund. o STRUCTURED NOTE RISK: The value of these notes will rise or fall in response to changes in the underlying commodity or related index. These notes expose the Fund to movements in commodity prices. These notes also are subject to risks, such as credit, market and interest rate risks, that in general affect the values of debt securities. These notes are often leveraged, increasing the volatility of each note's market value relative to changes in the underlying commodity, commodity futures contract or commodity index. Therefore, at the maturity of the note, the Fund may receive more or less principal than it originally invested. The Fund might receive interest payments on the note that are more or less than the stated coupon interest payments. o SWAP AGREEMENT RISKS: The Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap agreement counterparty. Swap agreements also may be considered to be illiquid. In addition, the Fund may enter into swap agreements that involve a limited number of counterparties, which may increase the Fund's exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties are willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its investment objective. o VALUATION RISK: The risk that the Fund has valued certain of its securities at a higher price than it can sell them.
