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 transactions costs and may mean higher taxes if you are investing in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Expense Example, affect the Fund's performance.

During the most recent fiscal year, the Fund's portfolio turnover rate was 440% of the average value of its portfolio.

The Example is intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example shows costs if you sold (redeemed) your shares at the end of the period or continued to hold them. The Example also assumes that your investment had 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:

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund invests at least 80% of its net assets (plus borrowings for investment purposes) in bonds of issuers in a number of different countries, which may include the United States. The Fund will provide shareholders with at least 60 days' prior written notice of any change in this investment policy.

The Fund may invest in securities of issuers located in developed and emerging market countries. Securities may be denominated in foreign currencies or in the U.S. dollar. The Fund may hedge its exposure to securities denominated in foreign currencies. The Fund may also borrow money from banks and invest the proceeds of such loans in portfolio securities as permitted under the Investment Company Act of 1940, and the rules, regulations and exemptive orders thereunder ("1940 Act"). This investment technique is known as "leveraging."

The Fund invests primarily in investment-grade securities which include, but are not limited to, corporate and government bonds which, at the time of investment, are rated investment-grade (at least BBB— by Standard & Poor's Ratings Services or Baa3 by Moody's Investors Service, Inc.) or have an equivalent rating by a nationally recognized statistical rating organization, or are of comparable quality if unrated. The Fund may also invest in preferred stocks, money market instruments, municipal bonds, commercial and residential mortgage-related securities, asset-backed securities, other securitized and structured debt products, private placements, and other investment companies. The Fund may also invest up to 5% of its assets in a combination of floating rate secured loans ("Senior Loans") and shares of ING Prime Rate Trust, a closed-end investment company that invests in Senior Loans. Although the Fund may invest a portion of its assets in high-yield debt securities rated below investment-grade, the Fund will seek to maintain a minimum weighted average portfolio quality rating of at least investment-grade. The dollar-weighted average portfolio duration of the Fund will generally range between two and nine years.

The Fund may use derivatives, including futures, swaps (including interest rate swaps, total return swaps and credit default swaps), and options, among others, to seek to enhance return, to hedge some of the risks of its investments in fixed-income securities or as a substitute for a position in an underlying asset. The Fund may, without limitation, seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as buy backs or dollar rolls and reverse repurchase agreements). The Fund may invest in other investment companies, including exchange-traded funds, to the extent permitted under the 1940 Act.

The investment process focuses on allocating assets among various sectors of the global bond markets and buying bonds at a discount to their intrinsic value. The sub-adviser ("Sub-Adviser") utilizes proprietary quantitative techniques to identify bonds or sectors that are cheap relative to other bonds or sectors based on their historical price relationships. Teams of asset specialists use this relative value analysis to guide them in the security selection process.

The Fund is non-diversified which means it may invest a significant portion of its assets in a single issuer.

The Sub-Adviser may sell securities for a variety of reasons, such as to secure gains, limit losses or redeploy assets into opportunities believed to be more promising, among others.

The Fund may lend portfolio securities on a short-term or long-term basis, up to 33¹/₃% of its assets.

Risk [Heading]

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

You could lose money on an investment in the Fund. Any of the following risks, among others, could affect Fund performance or cause the Fund to lose money or to underperform market averages of other funds.

Call During periods of falling interest rates, a bond issuer may "call" or repay its high-yielding bond before the bond's maturity date. If forced to invest the unanticipated proceeds at lower interest rates, the Fund would experience a decline in income.

Company The price of a given company's stock could decline or underperform for many reasons including, among others, poor management, financial problems, or business challenges. If a company declares bankruptcy or becomes insolvent, its stocks could become worthless.

Credit Prices of bonds and other debt securities can fall if the issuer's actual or perceived financial health deteriorates, whether because of broad economic or issuer-specific reasons. In severe cases, the issuer could be late in paying interest or principal, or could fail to pay altogether. Lower quality securities (including securities that have fallen below investment-grade and are classified as "junk bonds") have greater credit risk than higher quality (investment-grade) securities, and their issuers' long-term ability to make payments is considered speculative. Prices of lower quality bonds or other debt securities are also more volatile, are more sensitive to negative news about the economy or the issuer, and have greater liquidity and price volatility risk.

Currency To the extent that the Fund invests directly in foreign currencies or in securities denominated in, or that trade in, foreign (non-U.S.) currencies, it is subject to the risk that those currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged.

Derivative Instruments Derivative instruments are subject to a number of risks, including the risk of changes in the market price of the underlying securities, credit risk with respect to the counterparty, risk of loss due to changes in interest rates and liquidity risk. The use of certain derivatives may also have a leveraging effect which may increase the volatility of the Fund and reduce its returns.

Foreign Investments/Developing and Emerging Markets 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 smaller markets, differing reporting, accounting and auditing standards, and nationalization, expropriation or confiscatory taxation, foreign currency fluctuations, currency blockage, or political changes or diplomatic developments. Foreign investment risks typically are greater in developing and emerging markets than in developed markets.

High-Yield Securities Investments rated below investment-grade (or of similar quality if unrated) are known as "high-yield securities" or "junk bonds." High-yield securities are subject to greater levels of credit and liquidity risks. High-yield securities are considered primarily speculative with respect to the issuer's continuing ability to make principal and interest payments.

Interest in Loans The value and the income streams of interests in loans (including participation interests in lease financings and assignments in secured variable or floating rate loans) will decline if borrowers delay payments or fail to pay altogether. A large rise in interest rates could increase this risk. Although loans are generally fully collateralized when purchased, the collateral may become illiquid or decline in value. Many loans themselves carry liquidity and valuation risks.

Interest Rate With bonds and other fixed rate debt securities, a rise in interest rates generally causes values to fall; conversely, values generally rise as interest rates fall. The higher the credit quality of the security, and the longer its maturity or duration, the more sensitive it is likely to be to interest rate risk.

Investment Model The Sub-Adviser's proprietary model may not adequately allow for existing or unforeseen market factors or the interplay between such factors.

Issuer Non-Diversification The Fund is classified as a "non-diversified" investment company and, therefore, is subject to the risks of focusing investments in a small number of issuers, industries or foreign currencies, including being more susceptible to risks associated with a single economic, political or regulatory occurrence than a more diversified portfolio might be.

Leverage Certain transactions and investment strategies may give rise to leverage. Such transactions and investment strategies, include, but are not limited to: borrowing, dollar rolls, reverse repurchase agreements, loans of portfolio securities and the use of when-issued, delayed-delivery or forward-commitment transactions. The use of certain derivatives may also increase leveraging risk. The use of leverage may increase the Fund's expenses and increase the impact of the Fund's other risks.

Liquidity If a security is illiquid, the Fund might be unable to sell the security at a time when the Fund's manager might wish to sell, and the security could have the effect of decreasing the overall level of the Fund's liquidity. Further, the lack of an established secondary market may make it more difficult to value illiquid securities, which could vary from the amount the Fund could realize upon disposition. The Fund may make investments that become less liquid in response to market developments or adverse investor perception. The Fund could lose money if it cannot sell a security at the time and price that would be most beneficial to the Fund.

Market Stock prices are volatile and are affected by the real or perceived impacts of such factors as economic conditions and political events. The stock market tends to be cyclical, with periods when stock prices generally rise and periods when stock prices generally decline. Any given stock market segment may remain out of favor with investors for a short or long period of time, and stocks as an asset class may underperform bonds or other asset classes during some periods.

Mortgage-Related Securities Default on the underlying assets of the mortgage-related securities held by the Fund may impair the value of the securities and there may be limitations on the enforceability of any security interest granted with respect to those assets. These securities also present a higher degree of prepayment and extension risk and interest rate risk than do other types of fixed-income securities.

Municipal Obligations The municipal market in which the Fund invests is volatile and can be significantly affected by adverse tax, legislative, or political changes and the financial condition of the issuers of municipal securities.

Other Investment Companies The main risk of investing in other investment companies, including exchange-traded funds, is the risk that the value of the securities underlying an investment company might decrease. Because the Fund may invest in other investment companies, you will pay a proportionate share of the expenses of that other investment company (including management fees, administration fees and custodial fees) in addition to the expenses of the Fund.

Prepayment and Extension Prepayment risk is the risk that principal on mortgages or other loan obligations underlying a security may be repaid prior to the stated maturity date, which may reduce the market value of the security and the anticipated yield-to-maturity. Extension risk is the risk that an issuer will exercise its right to repay principal on an obligation held by the Fund later than expected, which may decrease the value of the obligation and prevent the Fund from investing expected repayment proceeds in securities paying yields higher than the yields paid by the securities that were expected to be repaid.

Securities Lending Securities lending involves two primary risks: "investment risk" and "borrower default risk." Investment risk is the risk that the Fund will lose money from the investment of the cash collateral received from the borrower. Borrower default risk is the risk that the Fund will lose money due to the failure of a borrower to return a borrowed security in a timely manner.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

PERFORMANCE INFORMATION

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The following information is intended to help you understand the risks of investing in the Fund. Because Class R shares of the Fund had not commenced operations as of the calendar year ended December 31, 2010, the following bar chart shows the changes in the Fund's Class C shares' performance from year to year, and the table compares the Fund's Class C shares' performance to the performance of a broad-based securities market index/indices for the same period. Class R shares and Class C shares of the Fund would have substantially similar performance because they invest in the same portfolio of securities. However, Class R shares' performance would be higher than Class C shares' performance because of the higher expenses paid by Class C shares. The Fund's performance information reflects applicable fee waivers and/or expense limitations in effect during the period presented. Absent such fee waivers/expense limitations, if any, performance would have been lower. The bar chart shows the performance of the Fund's Class C shares, but does not reflect the impact of contingent deferred sales charges. If it did, returns would be lower than those shown. The Fund's past performance (before and after taxes) is no guarantee of future results. For the most recent performance figures, go to www.INGFunds.com/literature or call 1-800-992-0180.
