Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a falsefalseInvestment Strategy, Heading30false0rr_StrategyNarrativeTextBlockrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00<pre>To pursue its goal, the fund normally invests at least 80% of its assets in bonds and other instruments that provide investment exposure to global bond markets. The fund normally invests opportunistically in bonds and other instruments that provide investment exposure to global bond and currency markets in seeking to produce absolute or real returns across economic cycles. The fund's investments will be focused globally among the developed and emerging capital markets of the world. The fund ordinarily invests in at least three countries, and, at times, may invest a substantial portion of its assets in a single country. The fund's portfolio managers employ a dynamic, unconstrained approach in allocating the fund's assets globally, principally among government bonds, emerging market sovereign debt, investment grade and high yield corporate instruments, and currencies. The fund obtains investment exposure to these fixed income asset classes and currencies by investing in securities and through derivative instruments. The fund may invest in the securities of companies of any market capitalization and securities of any credit quality, maturity or duration.The fund may invest in securities denominated in the local currency of issue or U.S. dollar-denominated securities. The fund's portfolio managers combine a top-down approach, emphasizing economic trends and current investment themes on a global basis, with bottom-up security selection based on fundamental research to allocate the fund's investments among and within fixed income asset classes and currencies. In choosing investments, the portfolio managers consider: key trends in global economic variables, such as gross domestic product, monetary and fiscal policies, trade and current account balances, inflation and interest rates; investment themes, such as changing demographics, the impact of new technologies and the globalization of industries and brands; relative valuations of equity securities, bonds and cash; long-term trends in currency movements; and company fundamentals. In constructing the fund's portfolio, the portfolio managers look for what they consider to be the best opportunities in the global fixed income and currency markets at any given time. The fund is not managed to a benchmark index. Rather than managing to track a benchmark index, the fund seeks to provide returns that are largely independent of market moves. The portfolio managers have considerable latitude in allocating the fund's investments and in selecting securities and derivative instruments to implement the fund's investment approach, and there is no limitation as to the amount of fund assets required to be invested in any one fixed income asset class or sector. The fund's portfolio will not have the same characteristics as its broad-based securities market index - the Citibank 30-Day Treasury Bill Index - or its synthetic securities market index - the BofA Merrill Lynch US Dollar 1-Month LIBOR Constant Maturity Index. The fund's performance baseline benchmark is US Dollar 1-Month LIBOR. The portfolio managers also assess and manage the overall risk profile of the fund's portfolio. The fund may use to a significant degree derivative instruments, such as options, futures and options on futures (including those relating to securities, indexes, foreign currencies and interest rates), forward contracts and swaps, in connection with its investment strategy. The fund also may use such derivatives as part of a hedging strategy or for other purposes related to the management of the fund. Derivatives may be entered into on established exchanges or through privately negotiated transactions referred to as over-the-counter derivatives. The fund also may purchase or sell securities on a forward commitment basis. The fund is non-diversified, which means that a relatively high percentage of the fund's assets may be invested in a limited number of issuers.</pre>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund. Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a falsefalseInvestment Strategy, Narrative31false0rr_RiskHeadingrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00PRINCIPAL RISKSfalsefalsefalsefalsefalseOtherxbrli:stringItemTypestringNarrative Risk Disclosure.Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Paragraph 1 -Subsection b falsefalseRisk, Heading32false0rr_RiskNarrativeTextBlockrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00<pre>An investment in the fund is not a bank deposit. It is not insured or guaranteed by the FDIC or any other government agency. It is not a complete investment program. The fund's share price fluctuates, sometimes dramatically, which means you could lose money. o Allocation risk. The ability of the fund to achieve its investment goal depends, in part, on the ability of the fund's portfolio managers to allocate effectively the fund's assets between global bonds and currencies, and among and within fixed income asset classes. There can be no assurance that the actual allocations will be effective in achieving the fund's investment goal. o Market risk. The market value of a security may decline due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. A security's market value also may decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry. o Market sector risk. The fund may significantly overweight or underweight certain companies, industries or market sectors, which may cause the fund's performance to be more or less sensitive to developments affecting those companies, industries or sectors. o Foreign investment risk. Special risks associated with investments in foreign issuers include exposure to currency fluctuations, less liquidity, less developed or less efficient trading markets, lack of comprehensive company information, political instability and differing auditing and legal standards. To the extent the fund's investments are concentrated in a limited number of foreign countries, the fund's performance could be more volatile than that of more geographically diversified funds. o Emerging market risk. The securities of issuers located in emerging markets tend to be more volatile and less liquid than the securities of issuers located in more mature economies, and emerging markets generally have less diverse and less mature economic structures and less stable political systems than those of developed countries. The securities of issuers located or doing substantial business in emerging markets are often subject to rapid and large changes in price. o Foreign currency risk. Investments in foreign currencies are subject to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of hedged positions, that the U.S. dollar will decline relative to the currency being hedged. o Foreign government obligations and sovereign debt risk. Investing in foreign government obligations and the sovereign debt of emerging market countries creates exposure to the direct or indirect consequences of political, social or economic changes in the countries that issue the securities or in which the issuers are located. The ability and willingness of sovereign obligors in emerging market countries or the governmental authorities that control repayment of their external debt to pay principal and interest on such debt when due may depend on general economic and political conditions within the relevant country, or numerous other factors. A governmental obligor may default on its obligations. o Credit risk. Failure of an issuer or guarantor of a fixed income security, or the counterparty to a derivatives transaction, to make timely interest or principal payments or otherwise honor its obligations could cause the fund to lose money. The sovereign ratings of certain emerging market countries, as well as the ratings of corporate debt securities, in which the fund may invest may be below investment grade ("high yield" or "junk" bonds). High yield ("junk") bonds involve greater credit risk, including the risk of default, than investment grade bonds, and are considered predominantly speculative with respect to the issuer's continuing ability to make principal and interest payments. o Interest rate risk. Prices of bonds tend to move inversely with changes in interest rates. Typically, a rise in rates will adversely affect bond prices and, accordingly, the fund's share price. The longer the effective maturity and duration of the fund's portfolio, the more the fund's share price is likely to react to interest rates. o Liquidity risk. When there is little or no active trading market for specific types of securities, it can become more difficult to sell the securities at or near their perceived value. In such a market, the value of such securities and the fund's share price may fall dramatically. Investments in foreign securities, particularly those of issuers located in emerging markets, tend to have greater exposure to liquidity risk than domestic securities. o Derivatives risk. A small investment in derivatives could have a potentially large impact on the fund's performance. The use of derivatives involves risks different from, or possibly greater than, the risks associated with investing directly in the underlying assets. Derivatives can be highly volatile, illiquid and difficult to value. Derivative instruments also involve the risk that a loss may be sustained as a result of the failure of the counterparty to the derivative instruments to make required payments or otherwise comply with the derivative instruments' terms. Additionally, some derivatives involve economic leverage, which could increase the volatility of these investments as they may fluctuate in value more than the underlying instrument. The fund may be required to segregate liquid assets, or otherwise cover its obligations, relating to the fund's transactions in derivatives. o Leveraging risk. The use of leverage, such as entering into futures contracts and forward currency contracts, engaging in forward commitment transactions, lending portfolio securities, and engaging in reverse repurchase agreements, may magnify the fund's gains or losses. Because many derivatives have a leverage component, adverse changes in the value or level of the underlying asset, reference rate or index can result in a loss substantially greater than the amount invested in the derivative itself. o Management risk. Management risk is the risk that the investment process used by the fund's portfolio managers could fail to achieve the fund's investment goal and cause your fund investment to lose value. o Non-diversification risk. Because the fund may invest a relatively high percentage of its assets in a limited number of issuers, the fund's performance may be more vulnerable to changes in the market value of a single issuer or group of issuers and more susceptible to risks associated with a single economic, political or regulatory occurrence than a diversified fund.</pre>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

The fund normally allocates its investments among emerging market equities, bonds and currencies. The portfolio construction process starts with the fund's portfolio managers assessing the risk and return expectations of equities, bonds and currencies for each emerging market country over a 12-month period. These expectations are guided primarily by the portfolio managers' common global macro-economic view and top-down country-specific outlooks. Moreover, these expectations also reflect the portfolio managers' bottom-up valuation assessments of individual securities. The fund's assets are then allocated to the more attractive emerging market asset classes and countries. After making asset and country allocation decisions, the portfolio managers select individual securities for the fund's portfolio. In choosing bonds and currency investments for the fund, the portfolio managers rely on in-depth fundamental analysis. The portfolio managers seek to anticipate shifts in country fundamentals and their impact on bond and currency valuations. Bond selection is underpinned by a detailed assessment of sovereign risk, which encompasses an analysis of debt sustainability, liquidity, inflation expectations, and institutional factors. In considering the attractiveness of local currency exposures (through investment in forward contracts, bonds or equities), the portfolio managers focus, among other things, on the balance of payments outlook for the relevant country. In choosing equity investments for the fund, the portfolio managers rely on in-depth fundamental analysis supported by proprietary quantitative models. A preference is given to companies whose business is focused on domestic consumption. The portfolio managers seek to identify attractive stocks with low relative price multiples and positive trends in earnings forecasts. The quantitative models used by the portfolio managers combine relative value characteristics (such as price/earnings and price/book ratios) and relative growth characteristics (estimated trends and revision ratios) to create a relative attractiveness score for each stock. The portfolio managers' fundamental analysis includes qualitatively reviewing the more attractively ranked stocks to assess the sustainability of a company's business momentum by analyzing the company's financial statements and meeting with management, suppliers, customers and competitors. The fund may, but is not required to, use derivative instruments, such as options, futures and options on futures (including those relating to securities, indexes, foreign currencies and interest rates), forward contracts and swaps, as a substitute for investing directly in equities, bonds and currencies, to increase returns, to manage credit, interest rate or currency risk, to manage the effective maturity or duration of the fund's portfolio, as part of a hedging strategy, or for other purposes related to the management of the fund. The fund is non-diversified, which means that a relatively high percentage of the fund's assets may be invested in a limited number of issuers.</pre>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund. Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a falsefalseInvestment Strategy, Narrative102false0rr_RiskHeadingrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00PRINCIPAL RISKSfalsefalsefalsefalsefalseOtherxbrli:stringItemTypestringNarrative Risk Disclosure.Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Paragraph 1 -Subsection b falsefalseRisk, Heading103false0rr_RiskNarrativeTextBlockrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00<pre>An investment in the fund is not a bank deposit. It is not insured or guaranteed by the FDIC or any other government agency. It is not a complete investment program. The fund's share price fluctuates, sometimes dramatically, which means you could lose money. o Allocation risk. The ability of the fund to achieve its investment goal depends, in part, on the ability of the fund's portfolio managers to allocate effectively the fund's assets among emerging market equities, bonds and currencies. There can be no assurance that the actual allocations will be effective in achieving the fund's investment goal. o Correlation risk. Although the prices of equity securities and fixed income securities, as well as other asset classes, often rise and fall at different times so that a fall in the price of one may be offset by a rise in the price of the other, in down markets the prices of these securities and asset classes can also fall in tandem. Because the fund allocates its investments among emerging market equities, bonds and currencies, the fund is subject to correlation risk. o Foreign investment risk. The fund's performance will be influenced by political, social and economic factors affecting investments in foreign issuers. Special risks associated with investments in foreign issuers include exposure to currency fluctuations, less liquidity, less developed or less efficient trading markets, lack of comprehensive company information, political instability and differing auditing and legal standards. To the extent the fund's investments are concentrated in a limited number of foreign countries, the fund's performance could be more volatile than that of more geographically diversified funds. o Emerging market risk. The securities of issuers located in emerging markets tend to be more volatile and less liquid than the securities of issuers located in more mature economies, and emerging markets generally have less diverse and less mature economic structures and less stable political systems than those of developed countries. The securities of issuers located or doing substantial business in emerging markets are often subject to rapid and large changes in price. o Foreign currency risk. Investments in foreign currencies are subject to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of hedged positions, that the U.S. dollar will decline relative to the currency being hedged. o Foreign government obligations and sovereign debt risk. Investing in foreign government obligations and the sovereign debt of emerging market countries creates exposure to the direct or indirect consequences of political, social or economic changes in the countries that issue the securities or in which the issuers are located. The ability and willingness of sovereign obligors in emerging market countries or the governmental authorities that control repayment of their external debt to pay principal and interest on such debt when due may depend on general economic and political conditions within the relevant country, or numerous other factors. A governmental obligor may default on its obligations. o Risks of stock investing. Stocks generally fluctuate more in value than bonds and may decline significantly over short time periods. There is the chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising prices and falling prices. The market value of a stock may decline due to general weakness in the stock market or because of factors that affect the company or its particular industry. o Credit risk. Failure of an issuer or guarantor of a fixed income security, or the counterparty to a derivatives transaction, to make timely interest or principal payments or otherwise honor its obligations could cause the fund to lose money. The sovereign ratings of certain emerging market countries, as well as the ratings of corporate debt securities, in which the fund may invest may be below investment grade ("high yield" or "junk" bonds). High yield ("junk") bonds involve greater credit risk, including the risk of default, than investment grade bonds, and are considered predominantly speculative with respect to the issuer's continuing ability to make principal and interest payments. o Interest rate risk. Prices of bonds tend to move inversely with changes in interest rates. Typically, a rise in rates will adversely affect bond prices and, accordingly, the fund's share price. The longer the effective maturity and duration of the fund's fixed income portfolio, the more the fund's share price is likely to react to interest rates. o Liquidity risk. When there is little or no active trading market for specific types of securities, it can become more difficult to sell the securities at or near their perceived value. In such a market, the value of such securities and the fund's share price may fall dramatically. Investments in foreign securities, particularly those of issuers located in emerging markets, tend to have greater exposure to liquidity risk than domestic securities. o Derivatives risk. A small investment in derivatives could have a potentially large impact on the fund's performance. The use of derivatives involves risks different from, or possibly greater than, the risks associated with investing directly in the underlying assets. Derivatives can be highly volatile, illiquid and difficult to value. o Non-diversification risk. Because the fund may invest a relatively high percentage of its assets in a limited number of issuers, the fund's performance may be more vulnerable to changes in the market value of a single issuer or group of issuers and more susceptible to risks associated with a single economic, political or regulatory occurrence than a diversified fund.</pre>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.
