Objective, Primary [Text Block]	rr_ObjectivePrimaryTextBlock	The Greater China Fund’s (the “Fund”) investment objective is to achieve long-term capital growth.
Expense [Heading]	rr_ExpenseHeading	Fees and Expenses of the Fund
Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for reduced sales charges if you and your family invest, or agree to invest, a certain amount in Nomura Partners Funds, Inc. (the “Corporation”). More information is available in the “Description of Share Classes” section of the Fund’s Prospectus and in the “Purchase and Redemption of Shares” section of the statement of additional information (“SAI”).

Portfolio Turnover [Heading]	rr_PortfolioTurnoverHeading	Portfolio Turnover
Portfolio Turnover [Text Block]	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 you hold Fund shares in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Examples, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 82% of the average value of its portfolio.
Portfolio Turnover, Rate	rr_PortfolioTurnoverRate	82.00%
Expenses Deferred Charges [Text Block]	rr_ExpensesDeferredChargesTextBlock	No contingent deferred sales charge (“CDSC”), except on purchases over $1,000,000, for which no front-end sales charge was paid, which are subject to a 1% CDSC for redemptions within twelve months of investing.
Expense Example [Heading]	rr_ExpenseExampleHeading	Expense Examples
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	The Examples are intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. They assume 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 the first Example, or hold your shares, in the second Example. They also assume that your investment has a 5% return each year and that the Fund’s operating expenses remain the same, except that the Fund’s expenses are reduced during the first year by a fee waiver and expense limitation agreement. Although your costs may be higher or lower, based on these assumptions your costs would be:
Expense Example by, Year, Caption [Text]	rr_ExpenseExampleByYearCaption	If you redeemed your Shares
Expense Example, No Redemption, By Year, Caption [Text]	rr_ExpenseExampleNoRedemptionByYearCaption	If you did not redeem your Shares
Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal circumstances, the Fund will invest at least 80% of its assets in equity securities of Chinese companies (companies located or having a principal trading market in China, Hong Kong or Taiwan) or instruments that have similar economic characteristics. Equity securities include common stocks and related securities, such as preferred stock, convertible securities and depositary receipts. Nomura Asset Management Hong Kong Limited (“NAM Hong Kong”), on behalf of the Fund, uses a proprietary quantitative investment process together with fundamental analysis. NAM Hong Kong, on behalf of the Fund, may engage in active and frequent trading in seeking to achieve the Fund’s investment objective. The Fund does not limit its investments to companies of any particular industry or size and may invest a significant portion of its assets in smaller and less seasoned issuers.
Risk [Heading]	rr_RiskHeading	Principal Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	The Fund cannot guarantee that it will achieve its investment objective. As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund. Certain risks related to an investment in the Fund are summarized below. You should consider an investment in the Fund as a long-term investment. The Fund’s returns will fluctuate over long and short periods. Equity Securities Risk – The Fund will invest in common stocks, which are a type of equity security that represent an ownership interest in a corporation. Common stocks are subject to greater fluctuations in market value than certain other asset classes as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions. The rights of common stockholders are subordinate to all other claims on a company’s assets, including debt holders and preferred stockholders. Therefore, the Fund could lose money if a company in which it invests becomes financially distressed. Geographic Concentration and Country Risk – A small number of companies and industries may represent a large portion of the market in a particular country or region, and these companies and industries can be sensitive to adverse social, political, economic or regulatory developments in that country or region. Because the Fund concentrates its investments in China, Hong Kong and Taiwan, the Fund’s performance is expected to be closely tied to economic and political conditions in those areas and geopolitical conditions in the China region. In addition, natural disasters might have substantial economic impacts on affected regions, at least temporarily. Foreign Exposure Risk – Foreign investments may be subject to different and, in some cases, less stringent regulatory and disclosure standards than U.S. investments. Also, political concerns, fluctuations in foreign currencies and differences in taxation, trading, settlement, custodial and other operational practices may result in foreign investments being more volatile and less liquid than U.S. investments. Foreign regulatory and fiscal policies may affect the ability to trade securities across markets. In addition, brokerage and transaction costs are generally higher for foreign securities than for U.S. investments. Emerging Markets Risk – The risks of foreign investments are typically greater in less developed countries, which are sometimes referred to as emerging markets. For example, political and economic structures in these countries may be changing rapidly, which can cause instability and greater risk of loss. These countries are also more likely to experience higher levels of inflation, deflation or currency devaluation, which could hurt their economies and securities markets. For these and other reasons, investments in emerging markets are often considered speculative. Smaller and Less Seasoned Companies Risk – Smaller companies and, to a greater extent, less seasoned companies, may have more limited product lines, markets and financial resources; their securities may trade less frequently and in more limited volume; and the prices of their securities may tend to be more volatile than those of larger, more established companies. Market, Exchange and Frequent Trading Risk – Foreign markets may differ widely in trading and execution capabilities, liquidity and expenses, including brokerage and transaction costs. In addition, active and frequent trading of securities involves higher expenses which could affect the Fund’s performance over time. High rates of portfolio turnover could also affect the tax efficiency of the Fund by accelerating the realization of taxable income to shareholders. The Fund’s portfolio turnover rate may be 100% or more. For a detailed description of these and other risks of investing in this Fund, please see the “Principal Investment Risks” section in the Prospectus and the “Investment Objectives, Policies and Strategies” section in the SAI.

[2] The Fund's advisor, Nomura Asset Management U.S.A. Inc. ("NAM USA"), has contractually agreed to waive its management fee and, if necessary, to reimburse the Fund so that total operating expenses of the Fund are limited to 1.70% (excluding distribution and service (12b-1) fees, interest expense and certain other expenses) until January 28, 2014. Amounts waived or reimbursed in a particular fiscal year may be recaptured by NAM USA within three years of the waiver or reimbursement to the extent that recoupment will not cause the Fund's expenses to exceed any expense limitation in place at the time those expenses were waived. The arrangement may not be terminated prior to January 28, 2014 except by action of the Board of Directors of the Corporation.

Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal circumstances, the Fund will invest at least 80% of its assets in equity securities of non-U.S. companies, either directly or through other Funds. Equity securities include common stocks and related securities, such as preferred stock, convertible securities and depositary receipts. The Fund will allocate its assets among various regions and countries, which may include the United States (but in no less than three different countries). The Fund may also invest a substantial amount of its assets (i.e., more than 25%) in issuers located in a single country or a limited number of countries. In the pursuit of attractive returns across a wide variety of exciting investment opportunities Nomura Asset Management U.K. Limited (“NAM UK”) seeks to add value principally through two sources: allocation and stock selection. NAM UK, on behalf of the Fund, may engage in active and frequent trading in seeking to achieve the Fund’s investment objective. When investing in Japan and Asia, NAM UK may make use of other Funds which form part of the Corporation’s structure, including, but not limited to, The Japan Fund and the Asia Pacific ex Japan Fund, to the extent permitted by applicable law. NAM UK may also invest directly in Japan and Asia. In other geographic areas, NAM UK expects to invest directly.

Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	The Fund cannot guarantee that it will achieve its investment objective. As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund. Certain risks related to an investment in the Fund are summarized below. You should consider an investment in the Fund as a long-term investment. The Fund’s returns will fluctuate over long and short periods. Equity Securities Risk – The Fund will invest in common stocks, which are a type of equity security that represent an ownership interest in a corporation. Common stocks are subject to greater fluctuations in market value than certain other asset classes as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions. The rights of common stockholders are subordinate to all other claims on a company’s assets, including debt holders and preferred stockholders. Therefore, the Fund could lose money if a company in which it invests becomes financially distressed. Foreign Exposure Risk – Foreign investments may be subject to different and, in some cases, less stringent regulatory and disclosure standards than U.S. investments. Also, political concerns, fluctuations in foreign currencies and differences in taxation, trading, settlement, custodial and other operational practices may result in foreign investments being more volatile and less liquid than U.S. investments. Foreign regulatory and fiscal policies may affect the ability to trade securities across markets. In addition, brokerage and transaction costs are generally higher for foreign securities than for U.S. investments. Emerging Markets Risk – The risks of foreign investments are typically greater in less developed countries, which are sometimes referred to as emerging markets. For example, political and economic structures in these countries may be changing rapidly, which can cause instability and greater risk of loss. These countries are also more likely to experience higher levels of inflation, deflation or currency devaluation, which could hurt their economies and securities markets. For these and other reasons, investments in emerging markets are often considered speculative. Smaller and Less Seasoned Companies Risk – Smaller companies and, to a greater extent, less seasoned companies, may have more limited product lines, markets and financial resources; their securities may trade less frequently and in more limited volume; and the prices of their securities may tend to be more volatile than those of larger, more established companies. Fund of Funds Risk – An investment in the Fund is subject to all the risks of an investment directly in the underlying funds the Fund holds. An investor in the Fund will pay both the Fund’s expenses and, indirectly, the management fees and other expenses of the underlying funds, although the management fee paid to NAM USA will be calculated by excluding investments in other Funds within the Corporation to avoid a layering of management fees; provided, however, that the management fee paid to NAM USA will be calculated by including investments in money market funds that comply with Rule 2a-7 under the Investment Company Act of 1940, as amended. Market, Exchange and Frequent Trading Risk – Foreign markets may differ widely in trading and execution capabilities, liquidity and expenses, including brokerage and transaction costs. In addition, active and frequent trading of securities involves higher expenses which could affect the Fund’s performance over time. High rates of portfolio turnover could also affect the tax efficiency of the Fund by accelerating the realization of taxable income to shareholders. The Fund’s portfolio turnover rate may be 100% or more. For a detailed description of these and other risks of investing in this Fund, please see the “Principal Investment Risks” section in the Prospectus and the “Investment Objectives, Policies and Strategies” section in the SAI.

[1] No contingent deferred sales charge (“CDSC”), except on purchases over $1,000,000, for which no front-end sales charge was paid, which are subject to a 1% CDSC for redemptions within twelve months of investing.

[2] The management fees are 0.85% of the average daily net assets, however, the fees are reduced by the assets invested in other Funds managed by the Advisor.

[3] Total annual fund operating expenses may not correspond to the ratio of expenses to average net assets shown in the Financial Highlights section of this prospectus, which reflects the operating expenses of the Fund and does not include Acquired Fund Fees and Expenses.

[4] Effective January 26, 2012, the Fund’s advisor, Nomura Asset Management U.S.A. Inc. (“NAM USA”), has contractually agreed to waive its management fee and, if necessary, to reimburse the Fund so that total operating expenses of the Fund are limited to 1.40% (excluding distribution and service (12b-1) fees, interest expense and certain other expenses) until January 28, 2014. NAM USA also has contractually agreed to reimburse the Fund for the amount of fees and expenses incurred indirectly by the Fund through its investment in other Funds of the Corporation through at least January 28, 2014. Amounts waived or reimbursed in a particular fiscal year may be recaptured by NAM USA within three years of the waiver or reimbursement to the extent that recoupment will not cause the Fund’s expenses to exceed any expense limitation in place at the time those expenses were waived with the exception of the aforementioned reimbursement for the fees and expenses incurred indirectly by the Fund through its investment in other Funds of the Corporation. The arrangement may not be terminated prior to January 28, 2014 except by action of the Board of Directors of the Corporation.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal circumstances, the Fund will invest at least 80% of its assets in equity securities of Indian companies or instruments that have similar economic characteristics. Equity securities include common stocks and related securities, such as preferred stock, convertible securities and depositary receipts. A majority of the equity securities of Indian companies in which the Fund invests will be publicly-traded securities. The Fund is non-diversified and may invest a relatively high percentage of its assets in a small number of issuers. Nomura Asset Management Singapore Limited (“NAM Singapore”), on behalf of the Fund, may engage in active and frequent trading in seeking to achieve the Fund’s investment objective. The Fund does not limit its investments to companies of any particular industry or size and may invest a significant portion of its assets in smaller and less seasoned issuers.
Risk [Heading]	rr_RiskHeading	Principal Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	The Fund cannot guarantee that it will achieve its investment objective. As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund. Certain risks related to an investment in the Fund are summarized below. You should consider an investment in the Fund as a long-term investment. The Fund’s returns will fluctuate over long and short periods. Equity Securities Risk – The Fund will invest in common stocks, which are a type of equity security that represent an ownership interest in a corporation. Common stocks are subject to greater fluctuations in market value than certain other asset classes as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions. The rights of common stockholders are subordinate to all other claims on a company’s assets, including debt holders and preferred stockholders. Therefore, the Fund could lose money if a company in which it invests becomes financially distressed. Geographic Concentration and Country Risk – A small number of companies and industries may represent a large portion of the market in a particular country or region, and these companies and industries can be sensitive to adverse social, political, economic or regulatory developments in that country or region. Because the Fund concentrates its investments in India, the Fund’s performance is expected to be closely tied to economic and political conditions in India and geopolitical conditions in India. There may be changes in the applicable laws and regulatory framework in India that may require the Fund and other entities to obtain registrations and/or make filings that are otherwise not required under the currently applicable framework. There are restrictions on foreign investment and exchange control regulations in India. There can be no assurance that these restrictions and regulations will not change in a way that makes it more difficult or impossible for the Fund to implement its investment objective. Foreign Exposure Risk – Foreign investments may be subject to different and, in some cases, less stringent regulatory and disclosure standards than U.S. investments. Also, political concerns, fluctuations in foreign currencies and differences in taxation, trading, settlement, custodial and other operational practices may result in foreign investments being more volatile and less liquid than U.S. investments. Foreign regulatory and fiscal policies may affect the ability to trade securities across markets. In addition, brokerage and transaction costs are generally higher for foreign securities than for U.S. investments. Emerging Markets Risk – The risks of foreign investments are typically greater in less developed countries, which are sometimes referred to as emerging markets. For example, political and economic structures in these countries may be changing rapidly, which can cause instability and greater risk of loss. These countries are also more likely to experience higher levels of inflation, deflation or currency devaluation, which could hurt their economies and securities markets. For these and other reasons, investments in emerging markets are often considered speculative. Smaller and Less Seasoned Companies Risk – Smaller companies and, to a greater extent, less seasoned companies, may have more limited product lines, markets and financial resources; their securities may trade less frequently and in more limited volume; and the prices of their securities may tend to be more volatile than those of larger, more established companies. Non-Diversification Risk – Because the Fund may invest a higher percentage of its assets in a small number of issuers, the Fund is more susceptible to any singular event affecting those issuers than is a diversified fund. Market, Exchange and Frequent Trading Risk – Foreign markets may differ widely in trading and execution capabilities, liquidity and expenses, including brokerage and transaction costs. In addition, active and frequent trading of securities involves higher expenses which could affect the Fund’s performance over time. High rates of portfolio turnover could also affect the tax efficiency of the Fund by accelerating the realization of taxable income to shareholders. The Fund’s portfolio turnover rate may be 100% or more. For a detailed description of these and other risks of investing in this Fund, please see the “Principal Investment Risks” section in the Prospectus and the “Investment Objectives, Policies and Strategies” section in the SAI.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund.

Expense Examples

The Examples are intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. They assume 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 the first Example, or hold your shares, in the second Example. They also assume that your investment has a 5% return each year and that the Fund’s operating expenses remain the same, except that the Fund’s expenses are reduced during the first year by fee waiver and expense limitation agreements. Although your costs may be higher or lower, based on these assumptions your costs would be:

If you redeemed your Shares

Expense Example INTERNATIONAL EQUITY FUND (USD $)	Class A	Class C	Class I
1-Year	739	256	158
3-Year	2,062	1,803	1,532
5-Year	3,335	3,266	2,858
10-Year	6,308	6,584	5,974

If you did not redeem your Shares

Expense Example, No Redemption INTERNATIONAL EQUITY FUND (USD $)	Class A	Class C	Class I
1-Year	739	256	158
3-Year	2,062	1,803	1,532
5-Year	3,335	3,266	2,858
10-Year	6,308	6,584	5,974

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 you hold Fund shares in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Examples, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 56% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Fund will invest at least 80% of its assets in equity securities of non-U.S. companies, either directly or through other Funds. Equity securities include common stocks and related securities, such as preferred stock, convertible securities and depositary receipts.

The Fund will allocate its assets among various regions and countries, which may include the United States (but in no less than three different countries). The Fund may also invest a substantial amount of its assets (i.e., more than 25%) in issuers located in a single country or a limited number of countries. In the pursuit of attractive returns across a wide variety of exciting investment opportunities Nomura Asset Management U.K. Limited (“NAM UK”) seeks to add value principally through two sources: allocation and stock selection. NAM UK, on behalf of the Fund, may engage in active and frequent trading in seeking to achieve the Fund’s investment objective. When investing in Japan and Asia, NAM UK may make use of other Funds which form part of the Corporation’s structure, including, but not limited to, The Japan Fund and the Asia Pacific ex Japan Fund, to the extent permitted by applicable law. NAM UK may also invest directly in Japan and Asia. In other geographic areas, NAM UK expects to invest directly.

Principal Risks

The Fund cannot guarantee that it will achieve its investment objective. As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund. Certain risks related to an investment in the Fund are summarized below.

You should consider an investment in the Fund as a long-term investment. The Fund’s returns will fluctuate over long and short periods.

Equity Securities Risk – The Fund will invest in common stocks, which are a type of equity security that represent an ownership interest in a corporation. Common stocks are subject to greater fluctuations in market value than certain other asset classes as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions. The rights of common stockholders are subordinate to all other claims on a company’s assets, including debt holders and preferred stockholders. Therefore, the Fund could lose money if a company in which it invests becomes financially distressed.

Foreign Exposure Risk – Foreign investments may be subject to different and, in some cases, less stringent regulatory and disclosure standards than U.S. investments. Also, political concerns, fluctuations in foreign currencies and differences in taxation, trading, settlement, custodial and other operational practices may result in foreign investments being more volatile and less liquid than U.S. investments. Foreign regulatory and fiscal policies may affect the ability to trade securities across markets. In addition, brokerage and transaction costs are generally higher for foreign securities than for U.S. investments.

Emerging Markets Risk – The risks of foreign investments are typically greater in less developed countries, which are sometimes referred to as emerging markets. For example, political and economic structures in these countries may be changing rapidly, which can cause instability and greater risk of loss. These countries are also more likely to experience higher levels of inflation, deflation or currency devaluation, which could hurt their economies and securities markets. For these and other reasons, investments in emerging markets are often considered speculative.

Smaller and Less Seasoned Companies Risk – Smaller companies and, to a greater extent, less seasoned companies, may have more limited product lines, markets and financial resources; their securities may trade less frequently and in more limited volume; and the prices of their securities may tend to be more volatile than those of larger, more established companies.

Fund of Funds Risk – An investment in the Fund is subject to all the risks of an investment directly in the underlying funds the Fund holds. An investor in the Fund will pay both the Fund’s expenses and, indirectly, the management fees and other expenses of the underlying funds, although the management fee paid to NAM USA will be calculated by excluding investments in other Funds within the Corporation to avoid a layering of management fees; provided, however, that the management fee paid to NAM USA will be calculated by including investments in money market funds that comply with Rule 2a-7 under the Investment Company Act of 1940, as amended.

Market, Exchange and Frequent Trading Risk – Foreign markets may differ widely in trading and execution capabilities, liquidity and expenses, including brokerage and transaction costs. In addition, active and frequent trading of securities involves higher expenses which could affect the Fund’s performance over time. High rates of portfolio turnover could also affect the tax efficiency of the Fund by accelerating the realization of taxable income to shareholders. The Fund’s portfolio turnover rate may be 100% or more.

For a detailed description of these and other risks of investing in this Fund, please see the “Principal Investment Risks” section in the Prospectus and the “Investment Objectives, Policies and Strategies” section in the SAI.

Bar Chart and Performance Information

The bar chart and table below show the returns for the Fund’s Class A shares and do not reflect sales loads. If sales loads were reflected, returns would be lower. Returns vary from year to year, which may provide an indication of the risks of investing in the Fund. The table shows the risks of investing in the Class A shares of the Fund by showing how Fund performance compares with a broad-based market index. The performance of both the Fund and the index vary over time. The table shows returns on a before-tax and after-tax basis for Class A shares. The Fund’s past performance (before and after taxes) is not an indication of how the Fund will perform in the future. Updated performance information is available online at www.nomurapartnersfunds.com.

NAM USA also has contractually agreed to reimburse the Fund for the amount of fees and expenses incurred indirectly by the Fund through its investment in other Funds of the Corporation through at least January 28, 2014. Amounts waived or reimbursed in a particular fiscal year may be recaptured by NAM USA within three years of the waiver or reimbursement to the extent that recoupment will not cause the Fund’s expenses to exceed any expense limitation in place at the time those expenses were waived with the exception of the aforementioned reimbursement for the fees and expenses incurred indirectly by the Fund through its investment in other Funds of the Corporation.

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 you hold Fund shares in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Examples, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 75% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Fund will invest at least 80% of its assets in securities of issuers in emerging markets (i.e., countries that have an emerging market as defined by Standard & Poor’s^® (S&P^®), countries or markets with low- to middle-income economies as classified by the World Bank, and other countries or markets with similar emerging characteristics) and other investments that are tied economically to emerging markets. The Fund may invest a substantial amount of its assets (i.e., more than 25%) in issuers located in a single country or limited number of countries. The Fund will invest primarily in common stocks across countries, but in no event will the Fund be invested in fewer than three different countries, as selected by Martin Currie Inc. (“Martin Currie”). Martin Currie, on behalf of the Fund, may engage in active and frequent trading in seeking to achieve the Fund’s investment objective.

Securities include common stocks, preferred stocks, convertible securities and warrants. The Fund will normally invest in common stocks. The Fund may also invest in Japanese real estate investment trusts (“J-REITs”) and Japanese exchange traded funds (“ETFs”). The Fund utilizes a “multi-manager” approach pursuant to which the Fund’s investments are allocated among experienced portfolio management teams who are responsible for large cap value, large cap growth and small cap growth/value blend investment styles. The Fund may engage in active and frequent trading in seeking to achieve its investment objective. The Fund does not limit its investments to companies of any particular industry or size and may invest a significant portion of its assets in smaller and less seasoned issuers.

Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	The Fund cannot guarantee that it will achieve its investment objective. As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund. Certain risks related to an investment in the Fund are summarized below. You should consider an investment in the Fund as a long-term investment. The Fund’s returns will fluctuate over long and short periods. Equity Securities Risk – The Fund will invest in common stocks, which are a type of equity security that represent an ownership interest in a corporation. Common stocks are subject to greater fluctuations in market value than certain other asset classes as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions. The rights of common stockholders are subordinate to all other claims on a company’s assets, including debt holders and preferred stockholders. Therefore, the Fund could lose money if a company in which it invests becomes financially distressed. Geographic Concentration and Country Risk – A small number of companies and industries may represent a large portion of the market in a particular country or region, and these companies and industries can be sensitive to adverse social, political, economic or regulatory developments in that country or region. Because the Fund concentrates its investments in Japan, the Fund’s performance is expected to be closely tied to economic and political conditions in Japan and geopolitical conditions in Asia and the Middle East. In addition, natural disasters might have substantial economic impacts on affected regions, at least temporarily. Foreign Exposure Risk – Foreign investments may be subject to different and, in some cases, less stringent regulatory and disclosure standards than U.S. investments. Also, political concerns, fluctuations in foreign currencies and differences in taxation, trading, settlement, custodial and other operational practices may result in foreign investments being more volatile and less liquid than U.S. investments. Foreign regulatory and fiscal policies may affect the ability to trade securities across markets. In addition, brokerage and transaction costs are generally higher for foreign securities than for U.S. investments. Smaller and Less Seasoned Companies Risk – Smaller companies and, to a greater extent, less seasoned companies, may have more limited product lines, markets and financial resources; their securities may trade less frequently and in more limited volume; and the prices of their securities may tend to be more volatile than those of larger, more established companies. Growth and Value Investing Risks – Growth stocks tend to be more expensive and more sensitive to changes in their earnings than other types of stocks. The price of value stocks may not increase as anticipated, and value stocks may not pay dividends, if other investors fail to recognize the issuer’s value or favor investing in faster-growing issuers. Exchange Traded Funds – ETFs seek to track the performance of securities indices. The market value of an ETF is expected to rise and fall with changes in the value of its underlying index, but an ETF’s return may not match the return of its underlying index as a result of expenses, cash flows and investment timing differences. Shares of ETFs have many of the same risks as direct investments in common stocks and bonds. REIT and J-REIT Risk – Investing in real estate investment trusts (“REITs”) involves many of the same risks associated with direct ownership of real estate, such as declines in market value, shortages of mortgage funds, changes in applicable laws, overbuilding and defaults by tenants and borrowers. REITs are subject to leverage risk when they borrow to finance acquisitions. The properties owned or leased by REITs may be subject to risks that are specific to certain industries or geographic regions. In addition, many real estate companies, including REITs, utilize leverage (and some may be highly leveraged), which increases stock market risk. J-REITs are subject to complex tax regulation in Japan and a failure to comply with those requirements could disqualify the J-REIT from special tax benefits and reduce the amount available for distribution to J-REIT investors. Market, Exchange and Frequent Trading Risk – Foreign markets may differ widely in trading and execution capabilities, liquidity and expenses, including brokerage and transaction costs. In addition, active and frequent trading of securities involves higher expenses which could affect the Fund’s performance over time. High rates of portfolio turnover could also affect the tax efficiency of the Fund by accelerating the realization of taxable income to shareholders. The Fund’s portfolio turnover rate may be 100% or more. For a detailed description of these and other risks of investing in this Fund, please see the “Principal Investment Risks” section in the Prospectus and the “Investment Objectives, Policies and Strategies” section in the SAI.

Expense Examples

The Examples are intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. They assume 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 the first Example, or hold your shares, in the second Example. They also assume that your investment has a 5% return each year and that the Fund’s operating expenses remain the same, except that the Fund’s expenses are reduced during the first year by a fee waiver and expense limitation agreement. Although your costs may be higher or lower, based on these assumptions your costs would be:

If you redeemed your Shares

Expense Example THE JAPAN FUND, INC. (USD $)	Class A	Class C	Class I	Class S
1-Year	752	263	163	171
3-Year	1,139	827	505	549
5-Year	1,550	1,417	871	951
10-Year	2,693	3,015	1,901	2,077

If you did not redeem your Shares

Expense Example, No Redemption THE JAPAN FUND, INC. (USD $)	Class A	Class C	Class I	Class S
1-Year	752	263	163	171
3-Year	1,139	827	505	549
5-Year	1,550	1,417	871	951
10-Year	2,693	3,015	1,901	2,077

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 you hold Fund shares in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Examples, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 34% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Fund will invest at least 80% of its assets in securities of Japanese issuers and other investments that are tied economically to Japan. Securities include common stocks, preferred stocks, convertible securities and warrants. The Fund will normally invest in common stocks. The Fund may also invest in Japanese real estate investment trusts (“J-REITs”) and Japanese exchange traded funds (“ETFs”). The Fund utilizes a “multi-manager” approach pursuant to which the Fund’s investments are allocated among experienced portfolio management teams who are responsible for large cap value, large cap growth and small cap growth/value blend investment styles. The Fund may engage in active and frequent trading in seeking to achieve its investment objective. The Fund does not limit its investments to companies of any particular industry or size and may invest a significant portion of its assets in smaller and less seasoned issuers.

Principal Risks

The Fund cannot guarantee that it will achieve its investment objective. As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund. Certain risks related to an investment in the Fund are summarized below.

You should consider an investment in the Fund as a long-term investment. The Fund’s returns will fluctuate over long and short periods.

Equity Securities Risk – The Fund will invest in common stocks, which are a type of equity security that represent an ownership interest in a corporation. Common stocks are subject to greater fluctuations in market value than certain other asset classes as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions. The rights of common stockholders are subordinate to all other claims on a company’s assets, including debt holders and preferred stockholders. Therefore, the Fund could lose money if a company in which it invests becomes financially distressed.

Geographic Concentration and Country Risk – A small number of companies and industries may represent a large portion of the market in a particular country or region, and these companies and industries can be sensitive to adverse social, political, economic or regulatory developments in that country or region.

Because the Fund concentrates its investments in Japan, the Fund’s performance is expected to be closely tied to economic and political conditions in Japan and geopolitical conditions in Asia and the Middle East. In addition, natural disasters might have substantial economic impacts on affected regions, at least temporarily.

Foreign Exposure Risk – Foreign investments may be subject to different and, in some cases, less stringent regulatory and disclosure standards than U.S. investments. Also, political concerns, fluctuations in foreign currencies and differences in taxation, trading, settlement, custodial and other operational practices may result in foreign investments being more volatile and less liquid than U.S. investments. Foreign regulatory and fiscal policies may affect the ability to trade securities across markets. In addition, brokerage and transaction costs are generally higher for foreign securities than for U.S. investments.

Smaller and Less Seasoned Companies Risk – Smaller companies and, to a greater extent, less seasoned companies, may have more limited product lines, markets and financial resources; their securities may trade less frequently and in more limited volume; and the prices of their securities may tend to be more volatile than those of larger, more established companies.

Growth and Value Investing Risks – Growth stocks tend to be more expensive and more sensitive to changes in their earnings than other types of stocks. The price of value stocks may not increase as anticipated, and value stocks may not pay dividends, if other investors fail to recognize the issuer’s value or favor investing in faster-growing issuers.

Exchange Traded Funds – ETFs seek to track the performance of securities indices. The market value of an ETF is expected to rise and fall with changes in the value of its underlying index, but an ETF’s return may not match the return of its underlying index as a result of expenses, cash flows and investment timing differences. Shares of ETFs have many of the same risks as direct investments in common stocks and bonds.

REIT and J-REIT Risk – Investing in real estate investment trusts (“REITs”) involves many of the same risks associated with direct ownership of real estate, such as declines in market value, shortages of mortgage funds, changes in applicable laws, overbuilding and defaults by tenants and borrowers. REITs are subject to leverage risk when they borrow to finance acquisitions. The properties owned or leased by REITs may be subject to risks that are specific to certain industries or geographic regions. In addition, many real estate companies, including REITs, utilize leverage (and some may be highly leveraged), which increases stock market risk. J-REITs are subject to complex tax regulation in Japan and a failure to comply with those requirements could disqualify the J-REIT from special tax benefits and reduce the amount available for distribution to J-REIT investors.

Market, Exchange and Frequent Trading Risk – Foreign markets may differ widely in trading and execution capabilities, liquidity and expenses, including brokerage and transaction costs. In addition, active and frequent trading of securities involves higher expenses which could affect the Fund’s performance over time. High rates of portfolio turnover could also affect the tax efficiency of the Fund by accelerating the realization of taxable income to shareholders. The Fund’s portfolio turnover rate may be 100% or more.

For a detailed description of these and other risks of investing in this Fund, please see the “Principal Investment Risks” section in the Prospectus and the “Investment Objectives, Policies and Strategies” section in the SAI.

Bar Chart and Performance Information

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal circumstances, the Fund will invest at least 80% of its assets in equity securities of companies in the Asia Pacific region, excluding Japan. Investments may be made either directly or through its investments in other funds. Equity securities include common stocks and related securities, such as preferred stock, convertible securities, depositary receipts and real estate investment trusts (“REITs”). Nomura Asset Management Singapore Limited (“NAM Singapore”), on behalf of the Fund, may engage in active and frequent trading in seeking to achieve the Fund’s investment objective. The Fund does not limit its investments to companies of any particular industry or size and may invest a significant portion of its assets in smaller and less seasoned issuers. The Fund may invest in the Greater China Fund and the India Fund, which are also series of the Corporation, to the extent permitted by applicable law.
Risk [Heading]	rr_RiskHeading	Principal Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	The Fund cannot guarantee that it will achieve its investment objective. As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund. Certain risks related to an investment in the Fund are summarized below. You should consider an investment in the Fund as a long-term investment. The Fund’s returns will fluctuate over long and short periods. Equity Securities Risk – The Fund will invest in common stocks, which are a type of equity security that represent an ownership interest in a corporation. Common stocks are subject to greater fluctuations in market value than certain other asset classes as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions. The rights of common stockholders are subordinate to all other claims on a company’s assets, including debt holders and preferred stockholders. Therefore, the Fund could lose money if a company in which it invests becomes financially distressed. Geographic Concentration and Country Risk – A small number of companies and industries may represent a large portion of the market in a particular country or region, and these companies and industries can be sensitive to adverse social, political, economic or regulatory developments in that country or region. Because the Fund concentrates its investments in the Asia Pacific region, exclusive of Japan, the Fund’s performance is expected to be closely tied to economic and political conditions in the Asia Pacific region and geopolitical conditions in the Asia Pacific region. In addition, natural disasters might have substantial economic impacts on affected regions, at least temporarily. Foreign Exposure Risk – Foreign investments may be subject to different and, in some cases, less stringent regulatory and disclosure standards than U.S. investments. Also, political concerns, fluctuations in foreign currencies and differences in taxation, trading, settlement, custodial and other operational practices may result in foreign investments being more volatile and less liquid than U.S. investments. Foreign regulatory and fiscal policies may affect the ability to trade securities across markets. In addition, brokerage and transaction costs are generally higher for foreign securities than for U.S. investments. Emerging Markets Risk – The risks of foreign investments are typically greater in less developed countries, which are sometimes referred to as emerging markets. For example, political and economic structures in these countries may be changing rapidly, which can cause instability and greater risk of loss. These countries are also more likely to experience higher levels of inflation, deflation or currency devaluation, which could hurt their economies and securities markets. For these and other reasons, investments in emerging markets are often considered speculative. Smaller and Less Seasoned Companies Risk – Smaller companies and, to a greater extent, less seasoned companies, may have more limited product lines, markets and financial resources; their securities may trade less frequently and in more limited volume; and the prices of their securities may tend to be more volatile than those of larger, more established companies. REIT Risk – Investing in REITs involves many of the same risks associated with direct ownership of real estate, such as declines in market value, shortages of mortgage funds, changes in applicable laws, overbuilding and defaults by tenants and borrowers. REITs are subject to leverage risk when they borrow to finance acquisitions. The properties owned or leased by REITs may be subject to risks that are specific to certain industries or geographic regions. In addition, many real estate companies, including REITs, utilize leverage (and some may be highly leveraged), which increases stock market risk. Fund of Funds Risk – An investment in the Fund is subject to all the risks of an investment directly in the underlying funds the Fund holds. An investor in the Fund will pay both the Fund’s expenses and, indirectly, the management fees and other expense of the underlying funds, although the management fee paid to NAM USA will be calculated by excluding investments in other Funds within the Corporation to avoid a layering of management fees; provided, however, that the management fee paid to NAM USA will be calculated by including investments in money market funds that comply with Rule 2a-7 under the Investment Company Act of 1940, as amended. Market, Exchange and Frequent Trading Risk – Foreign markets may differ widely in trading and execution capabilities, liquidity and expenses, including brokerage and transaction costs. In addition, active and frequent trading of securities involves higher expenses which could affect the Fund’s performance over time. High rates of portfolio turnover could also affect the tax efficiency of the Fund by accelerating the realization of taxable income to shareholders. The Fund’s portfolio turnover rate may be 100% or more. For a detailed description of these and other risks of investing in this Fund, please see the “Principal Investment Risks” section in the Prospectus and the “Investment Objectives, Policies and Strategies” section in the SAI.

Expense Examples

The Examples are intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. They assume 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 the first Example, or hold your shares, in the second Example. They also assume that your investment has a 5% return each year and that the Fund’s operating expenses remain the same, except that the Fund’s expenses are reduced during the first year by a fee waiver and expense limitation agreement. Although your costs may be higher or lower, based on these assumptions your costs would be:

If you redeemed your Shares

Expense Example INDIA FUND (USD $)	Class A	Class C	Class I
1-Year	762	273	173
3-Year	1,936	1,630	1,375
5-Year	3,084	2,940	2,556
10-Year	5,844	6,020	5,421

If you did not redeem your Shares

Expense Example, No Redemption INDIA FUND (USD $)	Class A	Class C	Class I
1-Year	762	273	173
3-Year	1,936	1,630	1,375
5-Year	3,084	2,940	2,556
10-Year	5,844	6,020	5,421

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 you hold Fund shares in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Examples, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 104% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Fund will invest at least 80% of its assets in equity securities of Indian companies or instruments that have similar economic characteristics. Equity securities include common stocks and related securities, such as preferred stock, convertible securities and depositary receipts. A majority of the equity securities of Indian companies in which the Fund invests will be publicly-traded securities. The Fund is non-diversified and may invest a relatively high percentage of its assets in a small number of issuers. Nomura Asset Management Singapore Limited (“NAM Singapore”), on behalf of the Fund, may engage in active and frequent trading in seeking to achieve the Fund’s investment objective. The Fund does not limit its investments to companies of any particular industry or size and may invest a significant portion of its assets in smaller and less seasoned issuers.

Principal Risks

The Fund cannot guarantee that it will achieve its investment objective. As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund. Certain risks related to an investment in the Fund are summarized below.

You should consider an investment in the Fund as a long-term investment. The Fund’s returns will fluctuate over long and short periods.

Equity Securities Risk – The Fund will invest in common stocks, which are a type of equity security that represent an ownership interest in a corporation. Common stocks are subject to greater fluctuations in market value than certain other asset classes as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions. The rights of common stockholders are subordinate to all other claims on a company’s assets, including debt holders and preferred stockholders. Therefore, the Fund could lose money if a company in which it invests becomes financially distressed.

Geographic Concentration and Country Risk – A small number of companies and industries may represent a large portion of the market in a particular country or region, and these companies and industries can be sensitive to adverse social, political, economic or regulatory developments in that country or region.

Because the Fund concentrates its investments in India, the Fund’s performance is expected to be closely tied to economic and political conditions in India and geopolitical conditions in India. There may be changes in the applicable laws and regulatory framework in India that may require the Fund and other entities to obtain registrations and/or make filings that are otherwise not required under the currently applicable framework.

There are restrictions on foreign investment and exchange control regulations in India. There can be no assurance that these restrictions and regulations will not change in a way that makes it more difficult or impossible for the Fund to implement its investment objective.

Foreign Exposure Risk – Foreign investments may be subject to different and, in some cases, less stringent regulatory and disclosure standards than U.S. investments. Also, political concerns, fluctuations in foreign currencies and differences in taxation, trading, settlement, custodial and other operational practices may result in foreign investments being more volatile and less liquid than U.S. investments. Foreign regulatory and fiscal policies may affect the ability to trade securities across markets. In addition, brokerage and transaction costs are generally higher for foreign securities than for U.S. investments.

Emerging Markets Risk – The risks of foreign investments are typically greater in less developed countries, which are sometimes referred to as emerging markets. For example, political and economic structures in these countries may be changing rapidly, which can cause instability and greater risk of loss. These countries are also more likely to experience higher levels of inflation, deflation or currency devaluation, which could hurt their economies and securities markets. For these and other reasons, investments in emerging markets are often considered speculative.

Smaller and Less Seasoned Companies Risk – Smaller companies and, to a greater extent, less seasoned companies, may have more limited product lines, markets and financial resources; their securities may trade less frequently and in more limited volume; and the prices of their securities may tend to be more volatile than those of larger, more established companies.

Non-Diversification Risk – Because the Fund may invest a higher percentage of its assets in a small number of issuers, the Fund is more susceptible to any singular event affecting those issuers than is a diversified fund.

Market, Exchange and Frequent Trading Risk – Foreign markets may differ widely in trading and execution capabilities, liquidity and expenses, including brokerage and transaction costs. In addition, active and frequent trading of securities involves higher expenses which could affect the Fund’s performance over time. High rates of portfolio turnover could also affect the tax efficiency of the Fund by accelerating the realization of taxable income to shareholders. The Fund’s portfolio turnover rate may be 100% or more.

For a detailed description of these and other risks of investing in this Fund, please see the “Principal Investment Risks” section in the Prospectus and the “Investment Objectives, Policies and Strategies” section in the SAI.

Bar Chart and Performance Information

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal circumstances, the Fund will invest at least 80% of its assets in a portfolio of high yield bonds rated below investment grade by Moody’s Investors Services Inc. (“Moody’s”), Standard & Poor’s Rating Services (“S&P”), or Fitch, Inc. (“Fitch”), or, if unrated, determined to be of comparable quality by Nomura Corporate Research and Asset Management Inc. (“NCRAM”). The Fund defines high yield bonds to include the following (provided they are unrated or rated below investment-grade): bank loans; payment-in-kind securities; deferred payment securities; fixed, variable and floating rate obligations; asset-backed securities; convertible securities; zero-coupon bonds; and debt obligations. The Fund may invest in new issuances of high yield bonds. The Fund may invest in distressed high yield bonds. NCRAM anticipates that the Fund will be invested in a diversified portfolio of high yield bonds. Maturity is not a consideration in selecting the Fund’s investments. The Fund may engage in active and frequent trading in seeking to achieve its investment objective. In addition to investing in high yield bonds, NCRAM can invest up to 20% of the Fund’s assets in a wide range of securities, including investment grade bonds, common stock, preferred securities and money market instruments. Up to 20% of the Fund’s assets may be invested in securities not denominated in U.S. dollars. The Fund may invest without limit in U.S. dollar-denominated securities of foreign issuers. The Fund’s foreign investments (U.S. dollar or non-U.S. dollar-denominated) may include companies in, or governments of emerging market countries.
Risk [Heading]	rr_RiskHeading	Principal Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	The Fund cannot guarantee that it will achieve its investment objective. As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund. Certain risks related to an investment in the Fund are summarized below. You should consider an investment in the Fund as a long-term investment. The Fund’s returns will fluctuate over long and short periods. High Yield Bonds Risk – The Fund’s investment in high yield bonds (also known as junk bonds) will subject the Fund to greater levels of credit and liquidity risks than funds that invest in higher rated securities. While offering greater opportunity for higher yields and capital growth, high yield bonds usually are subject to greater price volatility and may be less liquid than higher rated securities. An economic downturn or period of rising interest rates may adversely affect the market for these securities (see “Inflation Risk” below) and reduce the Fund’s ability to sell these securities (see “Liquidity Risk” below). These securities are considered to be high-risk investments, are speculative with respect to the capacity to pay interest and repay principal (see “Credit/Default Risk” below) and may be issued by companies that are highly leveraged, less creditworthy or financially distressed (see “Distressed Securities Risk” below). These securities are subject to greater risk of loss, greater sensitivity to interest rate and economic changes, valuation difficulties, and a potential lack of a secondary or public market for the securities. The market price of these securities can change suddenly and unexpectedly. You should not invest in the Fund unless you are willing to assume the greater risk associated with high yield bonds. Inflation (Interest Rate) Risk – Generally, high yield bonds will decrease in value when interest rates rise and increase in value when interest rates decline. Interest rate risk is the risk that the high yield bonds will decline in value because of increases in interest rates. Interest rate changes normally have a greater effect on the prices of longer-term high yield bonds than shorter-term high yield bonds. In addition, during periods of declining interest rates, the issuers of high yield bonds held by the Fund may prepay principal earlier than scheduled, forcing the Fund to reinvest in lower yielding debt securities. This is known as “Prepayment Risk” and may reduce the Fund’s income. Variable and floating rate securities are less sensitive to market interest rate changes, but may decline in value if their interest rates do not rise as much, or as quickly, as interest rates in general. Conversely, floating rate securities generally will not increase in value if interest rates decline. A decrease in market interest rates may adversely affect the income the Fund receives from such securities and the net asset value of the Fund’s shares. Credit/Default Risk – Credit risk refers to the possibility that the issuer of a security will not be able to make payments of interest and principal when due. If an issuer fails to pay interest or repay principal, the Fund’s income or share value may be reduced. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer. Liquidity Risk – Certain securities that are thinly traded or that otherwise might not be easily disposed in the course of regular trading may be deemed to be illiquid securities. Illiquid securities may trade at a discount from comparable, more liquid investments, and may be subject to wider fluctuations in market value. Also, the Fund may not be able to dispose of illiquid securities when that would be beneficial at a favorable time or price. The Fund may invest up to 15% of its assets in illiquid securities. Bank Loan Risk – The market for loans may not be highly liquid and the Fund may have difficulty selling them. These investments expose the Fund to the credit risk of the lending financial institutions and the underlying borrowers. Loans, like other high yield obligations, are subject to Inflation Risk, Prepayment Risk and the risk of nonpayment of scheduled interest and/or principal. Nonpayment would result in a reduction of income to the Fund, a reduction in the value of the loan experiencing nonpayment and a potential decrease in the NAV of the Fund. Loans are also subject to “Limited Information Risk” because the amount of public information available with respect to loans will generally be less extensive than that available for rated, registered or exchange-listed securities. As a result, the performance of the Fund and its ability to meet its investment objective is more dependent on the analytical ability of NCRAM than would be the case for a fund that invests primarily in rated, registered or exchange-listed securities. Equity Securities Risk – The Fund may hold or to a limited extent invest in common stocks, which are a type of equity security that represent an ownership interest in a corporation. Common stocks are subject to greater fluctuations in market value than certain other asset classes as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions. The rights of common stockholders are subordinate to all other claims on a company’s assets, including debt holders and preferred stockholders. Therefore, the Fund could lose money if a company in which it invests becomes financially distressed. Convertible Securities Risk – The market value of a convertible security performs like that of a regular debt security; that is, if market interest rates rise, the value of a convertible security usually falls. In addition, convertible securities are subject to the risk that the issuer will not be able to pay interest or dividends when due, and their market value may change based on changes in the issuer’s credit rating or the market’s perception of the issuer’s creditworthiness. Since it derives a portion of its value from the common stock into which it may be converted, a convertible security is also subject to the same types of market and issuer risks that apply to the underlying common stock. Distressed Securities Risk – Investing in distressed securities is speculative and involves significant risks. Distressed securities may be the subject of bankruptcy proceedings or in default as to the repayment of principal and/or interest or rated in the lower rating categories (Ca or lower by Moody’s and CC or lower by S&P or Fitch. Distressed securities frequently do not produce income and may require the Fund to bear certain extraordinary expenses in order to protect and recover its investment. Preferred Securities Risk – Preferred securities may pay fixed or adjustable rates of return. Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities. In addition, a company’s preferred securities generally pay dividends only after the company makes required payments to holders of its bonds and other debt. For this reason, the value of preferred securities will usually react more strongly than bonds and other debt to actual or perceived changes in the company’s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred stock of larger companies. Currency Risk – When the Fund invests in securities that trade in or receive revenues in foreign (non-U.S.) currencies it will be subject to the risk that those currencies may decline in value relative to the U.S. dollar. As a result, the Fund’s investments in foreign denominated securities may reduce the returns of the Funds. Foreign Exposure Risk – Foreign investments may be subject to different and, in some cases, less stringent regulatory and disclosure standards than U.S. investments. Also, political concerns, fluctuations in foreign currencies and differences in taxation, trading, settlement, custodial and other operational practices may result in foreign investments being more volatile and less liquid than U.S. investments. Foreign regulatory and fiscal policies may affect the ability to trade securities across markets. In addition, brokerage and transaction costs are generally higher for foreign securities than for U.S. investments. Emerging Market Risk – Foreign investment risk may be particularly high to the extent that the Fund invests in emerging market securities that are economically tied to countries with developing economies. These securities may involve market, credit, currency, liquidity, legal political and other risks different from, or greater than, the risks of investing in developed foreign countries. Frequent Trading Risk – Active and frequent trading of securities involves higher expenses, which could affect the Fund’s performance over time. High rates of portfolio turnover could also affect the tax efficiency of the Fund by accelerating the realization of taxable income to shareholders. The Fund’s portfolio turnover rate may be more than 100%. Market Risk and Selection Risk – Market risk is the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. Selection risk is the risk that the securities selected by NCRAM will underperform the markets, the relevant indices or the securities selected by other funds with similar investment objectives and investment strategies. This means you may lose money.

10-Year	6,378	6,642	6,013

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 you hold Fund shares in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Examples, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 45% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Fund will invest at least 80% of its assets in equity securities. The Fund seeks to focus on income-producing equity securities, such as common and preferred dividend-paying stocks and real estate investment trusts (“REITs”). The Fund may invest in other types of securities and invests in U.S. and non-U.S. issuers. Under normal market conditions, the Fund will invest significantly (at least 40% of its assets unless market conditions are not deemed favorable by Nomura Asset Management U.K. Limited (“NAM UK”), in which case the Fund would invest at least 30% of its assets) in non-U.S. companies. The Fund may invest a substantial amount of its assets (i.e., more than 25%) in issuers located in a single country or limited number of countries, but in no event will the Fund be invested in fewer than three different countries, as selected by NAM UK. NAM UK, on behalf of the Fund, may engage in active and frequent trading in seeking to achieve the Fund’s investment objective. The Fund does not limit its investments to companies of any particular industry or size and may invest a significant portion of its assets in smaller and less seasoned issuers.

Principal Risks

The Fund cannot guarantee that it will achieve its investment objective. As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund. Certain risks related to an investment in the Fund are summarized below.

You should consider an investment in the Fund as a long-term investment. The Fund’s returns will fluctuate over long and short periods.

Equity Securities Risk – The Fund will invest in common stocks, which are a type of equity security that represent an ownership interest in a corporation. Common stocks are subject to greater fluctuations in market value than certain other asset classes as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions. The rights of common stockholders are subordinate to all other claims on a company’s assets, including debt holders and preferred stockholders. Therefore, the Fund could lose money if a company in which it invests becomes financially distressed.

Foreign Exposure Risk – Foreign investments may be subject to different and, in some cases, less stringent regulatory and disclosure standards than U.S. investments. Also, political concerns, fluctuations in foreign currencies and differences in taxation, trading, settlement, custodial and other operational practices may result in foreign investments being more volatile and less liquid than U.S. investments. Foreign regulatory and fiscal policies may affect the ability to trade securities across markets. In addition, brokerage and transaction costs are generally higher for foreign securities than for U.S. investments.

Emerging Markets Risk – The risks of foreign investments are typically greater in less developed countries, which are sometimes referred to as emerging markets. For example, political and economic structures in these countries may be changing rapidly, which can cause instability and greater risk of loss. These countries are also more likely to experience higher levels of inflation, deflation or currency devaluation, which could hurt their economies and securities markets. For these and other reasons, investments in emerging markets are often considered speculative.

Smaller and Less Seasoned Companies Risk – Smaller companies and, to a greater extent, less seasoned companies, may have more limited product lines, markets and financial resources; their securities may trade less frequently and in more limited volume; and the prices of their securities may tend to be more volatile than those of larger, more established companies.

REIT Risk – Investing in REITs involves many of the same risks associated with direct ownership of real estate, such as declines in market value, shortages of mortgage funds, changes in applicable laws, overbuilding and defaults by tenants and borrowers. REITs are subject to leverage risk when they borrow to finance acquisitions. The properties owned or leased by REITs may be subject to risks that are specific to certain industries or geographic regions. In addition, many real estate companies, including REITs, utilize leverage (and some may be highly leveraged), which increases stock market risk.

Inflation Risk – The value of assets or income from the Fund’s investments may be worth less in the future if inflation decreases the value of money.

Market, Exchange and Frequent Trading Risk – Foreign markets may differ widely in trading and execution capabilities, liquidity and expenses, including brokerage and transaction costs. In addition, active and frequent trading of securities involves higher expenses which could affect the Fund’s performance over time. High rates of portfolio turnover could also affect the tax efficiency of the Fund by accelerating the realization of taxable income to shareholders. The Fund’s portfolio turnover rate may be 100% or more.

For a detailed description of these and other risks of investing in this Fund, please see the “Principal Investment Risks” section in the Prospectus and the “Investment Objectives Policies and Strategies” section in the SAI.

Bar Chart and Performance Information

The bar chart and table below show the returns for the Fund’s Class A shares and do not reflect sales loads. If sales loads were reflected, returns would be lower. Returns vary from year to year, which may provide an indication of the risks of investing in the Fund. The table shows the risks of investing in the Class A shares of the Fund by showing how Fund performance compares with a broad-based market index. The performance of both the Fund and the index vary over time. The table shows returns on a before-tax and after-tax basis for Class A shares. The Fund’s past performance (before and after taxes) is not an indication of how the Fund will perform in the future.

They also assume that your investment has a 5% return each year and that the Fund’s operating expenses remain the same, except that the Fund’s expenses are reduced during the first year by a fee waiver and expense limitation agreement. Although your costs may be higher or lower, based on these assumptions your costs would be:

If you redeemed your Shares

10-Year	6,352	6,683	6,000

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 you hold Fund shares in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Examples, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 82% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Fund will invest at least 80% of its assets in equity securities of Chinese companies (companies located or having a principal trading market in China, Hong Kong or Taiwan) or instruments that have similar economic characteristics. Equity securities include common stocks and related securities, such as preferred stock, convertible securities and depositary receipts. Nomura Asset Management Hong Kong Limited (“NAM Hong Kong”), on behalf of the Fund, uses a proprietary quantitative investment process together with fundamental analysis. NAM Hong Kong, on behalf of the Fund, may engage in active and frequent trading in seeking to achieve the Fund’s investment objective. The Fund does not limit its investments to companies of any particular industry or size and may invest a significant portion of its assets in smaller and less seasoned issuers.

Principal Risks

The Fund cannot guarantee that it will achieve its investment objective. As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund. Certain risks related to an investment in the Fund are summarized below.

You should consider an investment in the Fund as a long-term investment. The Fund’s returns will fluctuate over long and short periods.

Equity Securities Risk – The Fund will invest in common stocks, which are a type of equity security that represent an ownership interest in a corporation. Common stocks are subject to greater fluctuations in market value than certain other asset classes as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions. The rights of common stockholders are subordinate to all other claims on a company’s assets, including debt holders and preferred stockholders. Therefore, the Fund could lose money if a company in which it invests becomes financially distressed.

Geographic Concentration and Country Risk – A small number of companies and industries may represent a large portion of the market in a particular country or region, and these companies and industries can be sensitive to adverse social, political, economic or regulatory developments in that country or region.

Because the Fund concentrates its investments in China, Hong Kong and Taiwan, the Fund’s performance is expected to be closely tied to economic and political conditions in those areas and geopolitical conditions in the China region. In addition, natural disasters might have substantial economic impacts on affected regions, at least temporarily.

Foreign Exposure Risk – Foreign investments may be subject to different and, in some cases, less stringent regulatory and disclosure standards than U.S. investments. Also, political concerns, fluctuations in foreign currencies and differences in taxation, trading, settlement, custodial and other operational practices may result in foreign investments being more volatile and less liquid than U.S. investments. Foreign regulatory and fiscal policies may affect the ability to trade securities across markets. In addition, brokerage and transaction costs are generally higher for foreign securities than for U.S. investments.

Emerging Markets Risk – The risks of foreign investments are typically greater in less developed countries, which are sometimes referred to as emerging markets. For example, political and economic structures in these countries may be changing rapidly, which can cause instability and greater risk of loss. These countries are also more likely to experience higher levels of inflation, deflation or currency devaluation, which could hurt their economies and securities markets. For these and other reasons, investments in emerging markets are often considered speculative.

Smaller and Less Seasoned Companies Risk – Smaller companies and, to a greater extent, less seasoned companies, may have more limited product lines, markets and financial resources; their securities may trade less frequently and in more limited volume; and the prices of their securities may tend to be more volatile than those of larger, more established companies.

Market, Exchange and Frequent Trading Risk – Foreign markets may differ widely in trading and execution capabilities, liquidity and expenses, including brokerage and transaction costs. In addition, active and frequent trading of securities involves higher expenses which could affect the Fund’s performance over time. High rates of portfolio turnover could also affect the tax efficiency of the Fund by accelerating the realization of taxable income to shareholders. The Fund’s portfolio turnover rate may be 100% or more.

For a detailed description of these and other risks of investing in this Fund, please see the “Principal Investment Risks” section in the Prospectus and the “Investment Objectives, Policies and Strategies” section in the SAI.

Bar Chart and Performance Information

The bar chart and table below show the returns for the Fund’s Class A shares and do not reflect sales loads. If sales loads were reflected, returns would be lower. Returns vary from year to year, which may provide an indication of the risks of investing in the Fund. The table shows the risks of investing in the Class A shares of the Fund by showing how Fund performance compares with a broad-based market index. The performance of both the Fund and the index vary over time. The table shows returns on a before-tax and after-tax basis for Class A shares. The Fund’s past performance (before and after taxes) is not an indication of how the Fund will perform in the future. Updated performance information is available online at www.nomurapartnersfunds.com.

After-tax returns for Class C and I shares will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown in the table. After-tax returns shown are not relevant to investors who hold their shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

[1] No contingent deferred sales charge ("CDSC"), except on purchases over $1,000,000, for which no front-end sales charge was paid, which are subject to a 1% CDSC for redemptions within twelve months of investing.

[1] The Fund's advisor, Nomura Asset Management U.S.A. Inc. ("NAM USA"), has contractually agreed to waive its management fee and, if necessary, to reimburse the Fund so that total operating expenses of the Fund are limited to 1.70% (excluding distribution and service (12b-1) fees, interest expense and certain other expenses) until January 28, 2014. Amounts waived or reimbursed in a particular fiscal year may be recaptured by NAM USA within three years of the waiver or reimbursement to the extent that recoupment will not cause the Fund's expenses to exceed any expense limitation in place at the time those expenses were waived. The arrangement may not be terminated prior to January 28, 2014 except by action of the Board of Directors of the Corporation.

Under normal market conditions, the Fund will invest significantly (at least 40% of its assets unless market conditions are not deemed favorable by Nomura Asset Management U.K. Limited (“NAM UK”), in which case the Fund would invest at least 30% of its assets) in non-U.S. companies. The Fund may invest a substantial amount of its assets (i.e., more than 25%) in issuers located in a single country or limited number of countries, but in no event will the Fund be invested in fewer than three different countries, as selected by NAM UK. NAM UK, on behalf of the Fund, may engage in active and frequent trading in seeking to achieve the Fund’s investment objective. The Fund does not limit its investments to companies of any particular industry or size and may invest a significant portion of its assets in smaller and less seasoned issuers.
Risk [Heading]	rr_RiskHeading	Principal Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	The Fund cannot guarantee that it will achieve its investment objective. As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund. Certain risks related to an investment in the Fund are summarized below. You should consider an investment in the Fund as a long-term investment. The Fund’s returns will fluctuate over long and short periods. Equity Securities Risk – The Fund will invest in common stocks, which are a type of equity security that represent an ownership interest in a corporation. Common stocks are subject to greater fluctuations in market value than certain other asset classes as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions. The rights of common stockholders are subordinate to all other claims on a company’s assets, including debt holders and preferred stockholders. Therefore, the Fund could lose money if a company in which it invests becomes financially distressed. Foreign Exposure Risk – Foreign investments may be subject to different and, in some cases, less stringent regulatory and disclosure standards than U.S. investments. Also, political concerns, fluctuations in foreign currencies and differences in taxation, trading, settlement, custodial and other operational practices may result in foreign investments being more volatile and less liquid than U.S. investments. Foreign regulatory and fiscal policies may affect the ability to trade securities across markets. In addition, brokerage and transaction costs are generally higher for foreign securities than for U.S. investments. Emerging Markets Risk – The risks of foreign investments are typically greater in less developed countries, which are sometimes referred to as emerging markets. For example, political and economic structures in these countries may be changing rapidly, which can cause instability and greater risk of loss. These countries are also more likely to experience higher levels of inflation, deflation or currency devaluation, which could hurt their economies and securities markets. For these and other reasons, investments in emerging markets are often considered speculative. Smaller and Less Seasoned Companies Risk – Smaller companies and, to a greater extent, less seasoned companies, may have more limited product lines, markets and financial resources; their securities may trade less frequently and in more limited volume; and the prices of their securities may tend to be more volatile than those of larger, more established companies. REIT Risk – Investing in REITs involves many of the same risks associated with direct ownership of real estate, such as declines in market value, shortages of mortgage funds, changes in applicable laws, overbuilding and defaults by tenants and borrowers. REITs are subject to leverage risk when they borrow to finance acquisitions. The properties owned or leased by REITs may be subject to risks that are specific to certain industries or geographic regions. In addition, many real estate companies, including REITs, utilize leverage (and some may be highly leveraged), which increases stock market risk. Inflation Risk – The value of assets or income from the Fund’s investments may be worth less in the future if inflation decreases the value of money. Market, Exchange and Frequent Trading Risk – Foreign markets may differ widely in trading and execution capabilities, liquidity and expenses, including brokerage and transaction costs. In addition, active and frequent trading of securities involves higher expenses which could affect the Fund’s performance over time. High rates of portfolio turnover could also affect the tax efficiency of the Fund by accelerating the realization of taxable income to shareholders. The Fund’s portfolio turnover rate may be 100% or more. For a detailed description of these and other risks of investing in this Fund, please see the “Principal Investment Risks” section in the Prospectus and the “Investment Objectives Policies and Strategies” section in the SAI.

Expense Examples

The Examples are intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. They assume 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 the first Example, or hold your shares, in the second Example. They also assume that your investment has a 5% return each year and that the Fund’s operating expenses remain the same, except that the Fund’s expenses are reduced during the first year by a fee waiver and expense limitation agreement. Although your costs may be higher or lower, based on these assumptions your costs would be:

5-Year	2,587	2,460	1,912
10-Year	4,922	5,167	4,194

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 you hold Fund shares in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Examples, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 54% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Fund will invest at least 80% of its assets in equity securities of companies in the Asia Pacific region, excluding Japan. Investments may be made either directly or through its investments in other funds. Equity securities include common stocks and related securities, such as preferred stock, convertible securities, depositary receipts and real estate investment trusts (“REITs”). Nomura Asset Management Singapore Limited (“NAM Singapore”), on behalf of the Fund, may engage in active and frequent trading in seeking to achieve the Fund’s investment objective. The Fund does not limit its investments to companies of any particular industry or size and may invest a significant portion of its assets in smaller and less seasoned issuers. The Fund may invest in the Greater China Fund and the India Fund, which are also series of the Corporation, to the extent permitted by applicable law.

Principal Risks

The Fund cannot guarantee that it will achieve its investment objective. As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund. Certain risks related to an investment in the Fund are summarized below.

You should consider an investment in the Fund as a long-term investment. The Fund’s returns will fluctuate over long and short periods.

Equity Securities Risk – The Fund will invest in common stocks, which are a type of equity security that represent an ownership interest in a corporation. Common stocks are subject to greater fluctuations in market value than certain other asset classes as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions. The rights of common stockholders are subordinate to all other claims on a company’s assets, including debt holders and preferred stockholders. Therefore, the Fund could lose money if a company in which it invests becomes financially distressed.

Geographic Concentration and Country Risk – A small number of companies and industries may represent a large portion of the market in a particular country or region, and these companies and industries can be sensitive to adverse social, political, economic or regulatory developments in that country or region.

Because the Fund concentrates its investments in the Asia Pacific region, exclusive of Japan, the Fund’s performance is expected to be closely tied to economic and political conditions in the Asia Pacific region and geopolitical conditions in the Asia Pacific region. In addition, natural disasters might have substantial economic impacts on affected regions, at least temporarily.

Foreign Exposure Risk – Foreign investments may be subject to different and, in some cases, less stringent regulatory and disclosure standards than U.S. investments. Also, political concerns, fluctuations in foreign currencies and differences in taxation, trading, settlement, custodial and other operational practices may result in foreign investments being more volatile and less liquid than U.S. investments. Foreign regulatory and fiscal policies may affect the ability to trade securities across markets. In addition, brokerage and transaction costs are generally higher for foreign securities than for U.S. investments.

Emerging Markets Risk – The risks of foreign investments are typically greater in less developed countries, which are sometimes referred to as emerging markets. For example, political and economic structures in these countries may be changing rapidly, which can cause instability and greater risk of loss. These countries are also more likely to experience higher levels of inflation, deflation or currency devaluation, which could hurt their economies and securities markets. For these and other reasons, investments in emerging markets are often considered speculative.

Smaller and Less Seasoned Companies Risk – Smaller companies and, to a greater extent, less seasoned companies, may have more limited product lines, markets and financial resources; their securities may trade less frequently and in more limited volume; and the prices of their securities may tend to be more volatile than those of larger, more established companies.

REIT Risk – Investing in REITs involves many of the same risks associated with direct ownership of real estate, such as declines in market value, shortages of mortgage funds, changes in applicable laws, overbuilding and defaults by tenants and borrowers. REITs are subject to leverage risk when they borrow to finance acquisitions. The properties owned or leased by REITs may be subject to risks that are specific to certain industries or geographic regions. In addition, many real estate companies, including REITs, utilize leverage (and some may be highly leveraged), which increases stock market risk.

Fund of Funds Risk – An investment in the Fund is subject to all the risks of an investment directly in the underlying funds the Fund holds. An investor in the Fund will pay both the Fund’s expenses and, indirectly, the management fees and other expense of the underlying funds, although the management fee paid to NAM USA will be calculated by excluding investments in other Funds within the Corporation to avoid a layering of management fees; provided, however, that the management fee paid to NAM USA will be calculated by including investments in money market funds that comply with Rule 2a-7 under the Investment Company Act of 1940, as amended.

Market, Exchange and Frequent Trading Risk – Foreign markets may differ widely in trading and execution capabilities, liquidity and expenses, including brokerage and transaction costs. In addition, active and frequent trading of securities involves higher expenses which could affect the Fund’s performance over time. High rates of portfolio turnover could also affect the tax efficiency of the Fund by accelerating the realization of taxable income to shareholders. The Fund’s portfolio turnover rate may be 100% or more.

For a detailed description of these and other risks of investing in this Fund, please see the “Principal Investment Risks” section in the Prospectus and the “Investment Objectives, Policies and Strategies” section in the SAI.

Bar Chart and Performance Information

The bar chart and table below show the returns for the Fund’s Class A shares and do not reflect sales loads. If sales loads were reflected, returns would be lower.

These costs, which are not reflected in Annual Fund Operating Expenses or in the Examples illustrated above, affect the Fund’s performance.

Principal Investment Strategies

Under normal circumstances, the Fund will invest at least 80% of its assets in a portfolio of high yield bonds rated below investment grade by Moody’s Investors Services Inc. (“Moody’s”), Standard & Poor’s Rating Services (“S&P”), or Fitch, Inc. (“Fitch”), or, if unrated, determined to be of comparable quality by Nomura Corporate Research and Asset Management Inc. (“NCRAM”).

The Fund defines high yield bonds to include the following (provided they are unrated or rated below investment-grade): bank loans; payment-in-kind securities; deferred payment securities; fixed, variable and floating rate obligations; asset-backed securities; convertible securities; zero-coupon bonds; and debt obligations. The Fund may invest in new issuances of high yield bonds. The Fund may invest in distressed high yield bonds.

NCRAM anticipates that the Fund will be invested in a diversified portfolio of high yield bonds. Maturity is not a consideration in selecting the Fund’s investments. The Fund may engage in active and frequent trading in seeking to achieve its investment objective.

In addition to investing in high yield bonds, NCRAM can invest up to 20% of the Fund’s assets in a wide range of securities, including investment grade bonds, common stock, preferred securities and money market instruments. Up to 20% of the Fund’s assets may be invested in securities not denominated in U.S. dollars. The Fund may invest without limit in U.S. dollar-denominated securities of foreign issuers. The Fund’s foreign investments (U.S. dollar or non-U.S. dollar-denominated) may include companies in, or governments of emerging market countries.

Principal Risks

The Fund cannot guarantee that it will achieve its investment objective. As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund. Certain risks related to an investment in the Fund are summarized below.

You should consider an investment in the Fund as a long-term investment. The Fund’s returns will fluctuate over long and short periods.

High Yield Bonds Risk – The Fund’s investment in high yield bonds (also known as junk bonds) will subject the Fund to greater levels of credit and liquidity risks than funds that invest in higher rated securities. While offering greater opportunity for higher yields and capital growth, high yield bonds usually are subject to greater price volatility and may be less liquid than higher rated securities. An economic downturn or period of rising interest rates may adversely affect the market for these securities (see “Inflation Risk” below) and reduce the Fund’s ability to sell these securities (see “Liquidity Risk” below). These securities are considered to be high-risk investments, are speculative with respect to the capacity to pay interest and repay principal (see “Credit/Default Risk” below) and may be issued by companies that are highly leveraged, less creditworthy or financially distressed (see “Distressed Securities Risk” below). These securities are subject to greater risk of loss, greater sensitivity to interest rate and economic changes, valuation difficulties, and a potential lack of a secondary or public market for the securities. The market price of these securities can change suddenly and unexpectedly. You should not invest in the Fund unless you are willing to assume the greater risk associated with high yield bonds.

Inflation (Interest Rate) Risk – Generally, high yield bonds will decrease in value when interest rates rise and increase in value when interest rates decline. Interest rate risk is the risk that the high yield bonds will decline in value because of increases in interest rates. Interest rate changes normally have a greater effect on the prices of longer-term high yield bonds than shorter-term high yield bonds. In addition, during periods of declining interest rates, the issuers of high yield bonds held by the Fund may prepay principal earlier than scheduled, forcing the Fund to reinvest in lower yielding debt securities. This is known as “Prepayment Risk” and may reduce the Fund’s income.

Variable and floating rate securities are less sensitive to market interest rate changes, but may decline in value if their interest rates do not rise as much, or as quickly, as interest rates in general. Conversely, floating rate securities generally will not increase in value if interest rates decline. A decrease in market interest rates may adversely affect the income the Fund receives from such securities and the net asset value of the Fund’s shares.

Credit/Default Risk – Credit risk refers to the possibility that the issuer of a security will not be able to make payments of interest and principal when due. If an issuer fails to pay interest or repay principal, the Fund’s income or share value may be reduced. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer.

Liquidity Risk – Certain securities that are thinly traded or that otherwise might not be easily disposed in the course of regular trading may be deemed to be illiquid securities. Illiquid securities may trade at a discount from comparable, more liquid investments, and may be subject to wider fluctuations in market value. Also, the Fund may not be able to dispose of illiquid securities when that would be beneficial at a favorable time or price. The Fund may invest up to 15% of its assets in illiquid securities.

Bank Loan Risk – The market for loans may not be highly liquid and the Fund may have difficulty selling them. These investments expose the Fund to the credit risk of the lending financial institutions and the underlying borrowers. Loans, like other high yield obligations, are subject to Inflation Risk, Prepayment Risk and the risk of nonpayment of scheduled interest and/or principal. Nonpayment would result in a reduction of income to the Fund, a reduction in the value of the loan experiencing nonpayment and a potential decrease in the NAV of the Fund. Loans are also subject to “Limited Information Risk” because the amount of public information available with respect to loans will generally be less extensive than that available for rated, registered or exchange-listed securities. As a result, the performance of the Fund and its ability to meet its investment objective is more dependent on the analytical ability of NCRAM than would be the case for a fund that invests primarily in rated, registered or exchange-listed securities.

Equity Securities Risk – The Fund may hold or to a limited extent invest in common stocks, which are a type of equity security that represent an ownership interest in a corporation. Common stocks are subject to greater fluctuations in market value than certain other asset classes as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions. The rights of common stockholders are subordinate to all other claims on a company’s assets, including debt holders and preferred stockholders. Therefore, the Fund could lose money if a company in which it invests becomes financially distressed.

Convertible Securities Risk – The market value of a convertible security performs like that of a regular debt security; that is, if market interest rates rise, the value of a convertible security usually falls. In addition, convertible securities are subject to the risk that the issuer will not be able to pay interest or dividends when due, and their market value may change based on changes in the issuer’s credit rating or the market’s perception of the issuer’s creditworthiness. Since it derives a portion of its value from the common stock into which it may be converted, a convertible security is also subject to the same types of market and issuer risks that apply to the underlying common stock.

Distressed Securities Risk – Investing in distressed securities is speculative and involves significant risks. Distressed securities may be the subject of bankruptcy proceedings or in default as to the repayment of principal and/or interest or rated in the lower rating categories (Ca or lower by Moody’s and CC or lower by S&P or Fitch. Distressed securities frequently do not produce income and may require the Fund to bear certain extraordinary expenses in order to protect and recover its investment.

Preferred Securities Risk – Preferred securities may pay fixed or adjustable rates of return. Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities. In addition, a company’s preferred securities generally pay dividends only after the company makes required payments to holders of its bonds and other debt. For this reason, the value of preferred securities will usually react more strongly than bonds and other debt to actual or perceived changes in the company’s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred stock of larger companies.

Currency Risk – When the Fund invests in securities that trade in or receive revenues in foreign (non-U.S.) currencies it will be subject to the risk that those currencies may decline in value relative to the U.S. dollar. As a result, the Fund’s investments in foreign denominated securities may reduce the returns of the Funds.

Foreign Exposure Risk – Foreign investments may be subject to different and, in some cases, less stringent regulatory and disclosure standards than U.S. investments. Also, political concerns, fluctuations in foreign currencies and differences in taxation, trading, settlement, custodial and other operational practices may result in foreign investments being more volatile and less liquid than U.S. investments. Foreign regulatory and fiscal policies may affect the ability to trade securities across markets. In addition, brokerage and transaction costs are generally higher for foreign securities than for U.S. investments.

Emerging Market Risk – Foreign investment risk may be particularly high to the extent that the Fund invests in emerging market securities that are economically tied to countries with developing economies. These securities may involve market, credit, currency, liquidity, legal political and other risks different from, or greater than, the risks of investing in developed foreign countries.

Frequent Trading Risk – Active and frequent trading of securities involves higher expenses, which could affect the Fund’s performance over time. High rates of portfolio turnover could also affect the tax efficiency of the Fund by accelerating the realization of taxable income to shareholders. The Fund’s portfolio turnover rate may be more than 100%.

Market Risk and Selection Risk – Market risk is the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. Selection risk is the risk that the securities selected by NCRAM will underperform the markets, the relevant indices or the securities selected by other funds with similar investment objectives and investment strategies. This means you may lose money.
