Portfolio Turnover, Heading	rr_PortfolioTurnoverHeading	PORTFOLIO TURNOVER
Portfolio Turnover	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it buys or sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes if 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 98% of the average value of its portfolio.

Investment Strategy, Heading	rr_StrategyHeading	INVESTMENTS, RISKS AND PERFORMANCE
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	PRINCIPAL INVESTMENT STRATEGIES Under normal market conditions, the Fund invests at least 85% of its assets in a diversified portfolio of equity (or equity-related) securities of foreign issuers, including: o Common stocks of foreign issuers; o Preferred stocks and/or debt securities that are convertible into securities of foreign issuers or that otherwise exhibit equity- like characteristics; o Equity securities of foreign issuers listed or traded in the form of depositary receipts, including but not limited to European Depositary Receipts, Global Depositary Receipts, American Depositary Receipts and non-voting depositary receipts; and o Open-end or closed-end investment companies that primarily invest in the equity securities of issuers in a single country or geographic region directly, including exchange traded funds ("ETFs"). The Fund utilizes a multi-manager strategy in which the investment adviser, Rodney Square Management Corporation ("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 will limit investment in emerging market securities to no more than 35% of its assets. The Fund may attempt to hedge against currency risks associated with its portfolio securities by using forward foreign currency exchange contracts. The Fund may also invest in fully collateralized equity index futures as a substitute for conventional equity 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 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 chanes 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 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 PREFERRED STOCK RISK: In addition to general market conditions or issuer-specific events, the value of a preferred stock may be affected by interest rates, the credit quality of the issuing corporation and any call provisions. o VALUATION RISK: The risk that the Fund has valued certain of its securities at a higher price than it can sell them.
Risk, Lose Money	rr_RiskLoseMoney	You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments.
Risk, Not Insured Depository Institution	rr_RiskNotInsuredDepositoryInstitution	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.
