Example

This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. The example assumes 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, that your investment has a 5% return each year, and that the fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example	1 year	3 years	5 years	10 years

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 the fund’s shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s performance. During the most recent fiscal year, the fund’s portfolio turnover rate was 44.7% of the average value of its portfolio.

Investments, Risks, and Performance Principal Investment Strategies

The fund will normally invest at least 80% (and potentially all) of its net assets (including any borrowings for investment purposes) in debt securities of emerging market governments or companies located in emerging market countries. The fund considers frontier markets to be a subset of emerging markets and any investments in frontier markets will be counted toward the fund’s 80% investment policy. The fund relies on a classification by either JP Morgan or the International Monetary Fund to determine which countries are emerging markets. The fund’s holdings may be denominated in U.S. dollars or non-U.S. dollar currencies, including emerging market currencies. The extent, if any, to which the fund attempts to cushion the impact of foreign currency fluctuations on the U.S. dollar depends on market conditions. The fund’s holdings may include the lowest-rated bonds, including those in default, and there are no overall limits on the fund’s investments that are rated below investment-grade (BB or lower, or an equivalent rating), also known as “junk” bonds.

Although the fund expects to maintain an intermediate- to long-term weighted average maturity, there are no maturity restrictions on the overall portfolio or on individual securities. Security selection relies heavily on research, which analyzes political and economic trends as well as creditworthiness. The fund allocates investments among a variety of emerging markets (1) in order to establish a diverse portfolio; (2) based on the relative value of opportunities and associated risks within one country versus others; and (3) with a view to the liquidity of each particular market. The fund tends to favor bonds it expects will be upgraded. The fund sells holdings for a variety of reasons, such as to adjust its average maturity or credit quality, to shift assets into and out of higher-yielding securities, or to alter geographic or currency exposure.

The fund is “nondiversified,” meaning it may invest a greater portion of its assets in fewer issuers than is permissible for a “diversified” fund.

While most assets will be invested in bonds, the fund may enter into forward currency exchange contracts in keeping with its objective(s). Forward currency exchange contracts would primarily be used to help protect the fund’s non-U.S. dollar denominated holdings from unfavorable changes in foreign currency exchange rates, although other currency hedging techniques may be used from time to time.

Principal Risks

As with any fund, there is no guarantee that the fund will achieve its objective(s). The fund’s share price fluctuates, which means you could lose money by investing in the fund. The principal risks of investing in this fund, which may be even greater during periods of market disruption or volatility, are summarized as follows:

Market conditions The value of the fund’s investments may decrease, sometimes rapidly or unexpectedly, due to factors affecting an issuer held by the fund, particular industries, or the overall securities markets. A variety of factors can increase the volatility of the fund’s holdings and markets generally, including political or regulatory developments, recessions, inflation, rapid interest rate changes, war or acts of terrorism, natural disasters, and outbreaks of infectious illnesses or other widespread public health issues. Certain events may cause instability across global markets, including reduced liquidity and disruptions in trading markets, while some events may affect certain geographic regions, countries, sectors, and industries more significantly than others. These adverse developments may cause broad declines in market value due to short-term market movements or for significantly longer periods during more prolonged market downturns.

International investing Investing in the securities of non-U.S. issuers involves special risks not typically associated with investing in U.S. issuers. Non-U.S. securities tend to be more volatile and have lower overall liquidity than investments in U.S. securities and may lose value because of adverse local, political, social, or economic developments overseas, or due to changes in the exchange rates between foreign currencies and the U.S. dollar. In addition, investments outside the U.S. are subject to settlement practices and regulatory and financial reporting standards that differ from those of the U.S. The risks of investing outside the U.S. are heightened for any investments in emerging markets, which are susceptible to greater volatility than investments in developed markets.

Emerging markets Investments in emerging market countries are subject to greater risk and overall volatility than investments in the U.S. and developed markets. Emerging market countries tend to have economic structures that are less diverse and mature, and political systems that are less stable, than those of developed countries. In addition to the risks associated with investing outside the U.S., emerging markets are more susceptible to governmental interference, political and economic uncertainty, local taxes and restrictions on the fund’s investments, less efficient trading markets with lower overall liquidity, and more volatile currency exchange rates.

Frontier markets Frontier markets generally have smaller economies and less mature capital markets than emerging markets. As a result, the risks associated with investing in emerging market countries are magnified in frontier market countries. Frontier markets are more susceptible to abrupt changes in currency values, have less mature markets and settlement practices, and can have lower trading volumes that could lead to greater price volatility and illiquidity. Investor protections in frontier market countries may be limited and settlement procedures and custody services may prove inadequate in certain markets.

Investing in Latin America Many Latin American countries have histories of inflation, government overspending, political instability, high interest, and extreme currency fluctuations. Many of these countries tend to be highly reliant on the exportation of commodities so their economies may be significantly impacted by fluctuations in commodity prices and the global demand for certain commodities.

Currency exposure Because the fund invests in securities issued in foreign currencies, the fund is subject to the risk that it could experience losses based solely on the weakness of foreign currencies versus the U.S. dollar and changes in the exchange rates between such currencies and the U.S. dollar.

Fixed income markets Economic and other market developments can adversely affect the fixed income securities markets. At times, participants in these markets may develop concerns about the ability of certain issuers of debt instruments to make timely principal and interest payments, or they may develop concerns about the ability of financial institutions that make markets in certain debt instruments to facilitate an orderly market. Those concerns could cause increased volatility and reduced liquidity in particular securities or in the overall fixed income markets and the related derivatives markets. A lack of liquidity or other adverse credit market conditions may hamper the fund’s ability to sell the debt instruments in which it invests or to find and purchase suitable debt instruments.

Sector exposure At times, the fund may have a significant portion of its assets invested in securities of issuers conducting business in a broadly related group of industries within the same economic sector. Issuers in the same economic sector may be similarly affected by economic or market events, making the fund more vulnerable to unfavorable developments in that economic sector than funds that invest more broadly.

Junk investing Investments in bonds that are rated below investment grade, commonly referred to as junk bonds, expose the fund to greater volatility and credit risk than investments in bonds that are rated investment-grade. Issuers of junk bonds are usually not as strong financially and are more likely to suffer an adverse change in financial condition that would result in the inability to meet a financial obligation. As a result, bonds rated below investment grade carry a higher risk of default and should be considered speculative.

Credit quality An issuer of a debt instrument could suffer an adverse change in financial condition that results in a payment default (failure to make scheduled interest or principal payments), rating downgrade, or inability to meet a financial obligation. Securities that are rated below investment grade carry greater risk of default and should be considered speculative.

Interest rates The prices of, and the income generated by, debt instruments held by the fund may be affected by changes in interest rates. A rise in interest rates typically causes the price of a fixed rate debt instrument to fall and its yield to rise. Conversely, a decline in interest rates typically causes the price of a fixed rate debt instrument to rise and the yield to fall. Generally, funds with longer weighted average maturities and durations carry greater interest rate risk.

Derivatives The use of forward currency exchange contracts exposes the fund to greater volatility and losses in comparison to investing directly in foreign bonds. Forward currency exchange contracts are also subject to the risks that anticipated currency movements will not be accurately predicted, a counterparty will fail to perform in accordance with the terms of the agreement, and the risk that potential government regulation could negatively affect the fund’s investments in such instruments. Changes in regulations could significantly impact the fund’s ability to invest in specific types of derivatives, which could limit the fund’s ability to employ certain strategies that use derivatives.

Nondiversification As a nondiversified fund, the fund has the ability to invest a larger percentage of its assets in the securities of a smaller number of issuers than a diversified fund. As a result, poor performance by a single issuer could adversely affect fund performance more than if the fund were invested in a larger number of issuers. The fund’s share price can be expected to fluctuate more than that of a similar fund that is more broadly diversified.

Liquidity The fund may not be able to meet requests to redeem shares issued by the fund without significant dilution of the remaining shareholders’ interest in the fund. In addition, the fund may not be able to sell a holding in a timely manner at a desired price. Reduced liquidity in the bond markets can result from a number of events, such as limited trading activity, reductions in bond inventory, and rapid or unexpected changes in interest rates. Markets with lower overall liquidity could lead to greater price volatility and limit the fund’s ability to sell a holding at a suitable price.

Active management The fund’s overall investment program and holdings selected by the fund’s investment adviser may underperform the broad markets, relevant indices, or other funds with similar objectives and investment strategies.

Performance

The following performance information provides some indication of the risks of investing in the fund. The fund’s performance information represents only past performance (before and after taxes) and is not necessarily an indication of future results.

The following bar chart illustrates how much returns can differ from year to year by showing calendar year returns and the best and worst calendar quarter returns during those years for the fund.

The following table shows the average annual total returns for the fund, and also compares the returns with the returns of a relevant broad-based market index, as well as with the returns of one or more comparative indexes that have investment characteristics similar to those of the fund, if applicable.

In addition, the table shows hypothetical after-tax returns to demonstrate how taxes paid by a shareholder may influence returns. 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. After-tax returns shown are not relevant to investors who hold their fund shares through tax-deferred arrangements, such as a 401(k) account or an IRA.
