Fund Summary

Fund/Class:

Fidelity® Sustainable Target Date Income Fund

/Fidelity® Sustainable Target Date Income Fund

Investment Objective

Fidelity® Sustainable Target Date Income Fund seeks high current income and, as a secondary objective, capital appreciation.

Fee Table

The following table describes the fees and expenses that may be incurred when you buy, hold, and sell shares of the fund. In addition to the fees and expenses described below, your broker may also require you to pay other fees, such as brokerage commissions on purchases and sales of certain classes of shares of the fund and other fees to financial intermediaries, which are not reflected in the tables and examples below.

Shareholder fees

(fees paid directly from your investment) None

Annual Operating Expenses

(expenses that you pay each year as a % of the value of your investment)

Management fee	0.41%A
Distribution and/or Service (12b-1) fees	None
Other expenses	0.00%
Total annual operating expenses	0.41%A

AAdjusted to reflect current fees.

This example helps compare the cost of investing in the fund with the cost of investing in other funds.

Let's say, hypothetically, that the annual return for shares of the fund is 5% and that the fees and the annual operating expenses for shares of the fund are exactly as described in the fee table. This example illustrates the effect of fees and expenses, but is not meant to suggest actual or expected fees and expenses or returns, all of which may vary. For every $10,000 you invested, here's how much you would pay in total expenses if you sell all of your shares at the end of each time period indicated:

1 year	$	42
3 years	$	132
5 years	$	230
10 years	$	518

Portfolio Turnover

The fund will not incur transaction costs, such as commissions, when it buys and sells shares of underlying Fidelity® funds (or "turns over" its portfolio), but it could incur transaction costs if it were to buy and sell other types of securities directly. If the fund were to buy and sell other types of securities directly, a higher portfolio turnover rate could indicate higher transaction costs and could result in higher taxes when fund shares are held in a taxable account. Such costs, if incurred, would not be reflected in annual operating expenses or in the example and would affect the fund's performance. For the period from May 11, 2023 to March 31, 2024, the fund's portfolio turnover rate was 29% (annualized) of the average value of its portfolio.

Principal Investment Strategies

• Investing at least 80% of assets in underlying funds that are (i) Fidelity® funds that invest in securities of issuers that Fidelity Management & Research Company LLC (FMR) (the Adviser) believes have proven or improving sustainability practices or positive environmental, social and governance (ESG) characteristics (Fidelity® Sustainable Funds), (ii) Fidelity index funds that track an ESG Index (Fidelity® Sustainable Index Funds), and (iii) Fidelity® funds that do not have a principal ESG investment strategy but invest at least 80% of assets in U.S. and international sovereign or government-related debt securities that the Fidelity® Sustainable Target Date Fund Adviser believes have positive ESG characteristics (Fidelity® Traditional Funds) (collectively, underlying Fidelity® Funds).
• Evaluating each security in which a Fidelity® Traditional Fund invests to determine whether 80% of assets are invested in sovereign or government-related debt securities whose issuers have positive ESG characteristics by considering the sustainability practices of the country or other issues based on an evaluation of such issuer's individual ESG profile using the Adviser's proprietary ESG ratings process.
• The Adviser's proprietary ESG ratings process evaluates the current state of an issuer's sustainability practices using a data-driven framework that includes both proprietary and third-party data, and also provides a qualitative forward-looking assessment of an issuer's sustainability outlook provided by the Adviser's fundamental research analysts and ESG team.
• Allocating assets according to a stable neutral asset allocation strategy (approximately 11% in U.S. equity funds, 8% in international equity funds, 43% in U.S. investment grade bond funds, 5% in international bond funds, 3% in long-term treasury bond funds, 0% in long-term inflation-protected bond funds, 20% in short-term inflation protected bond funds, and 10% in short-term funds). The Adviser may modify the fund's neutral asset allocations from time to time when in the interests of shareholders.
• Buying and selling futures contracts (both long and short positions) in an effort to manage cash flows efficiently, remain fully invested, or facilitate asset allocation.
• Allocating assets among underlying Fidelity® funds and futures according to a stable neutral asset allocation of approximately:

	U.S. Equity Funds 11%
	International Equity Funds 8%
	International Bond Funds 5%
	U.S. Investment Grade Bond Funds 43%
	Long-Term Treasury Bond Funds 3%
	Long-Term Inflation-Protected Bond Funds 0%
	Short-Term Inflation-Protected Bond Funds 20%
	Short-Term Funds 10%

* The Adviser may change these percentages over time. As a result of the active asset allocation strategy (discussed below), actual allocations may differ from the neutral allocations above. The allocation percentages may not add to 100% due to rounding.

• The Adviser, under normal market conditions, will use an active asset allocation strategy to increase or decrease asset class exposures relative to the neutral asset allocations reflected above by up to 10% for equity funds, bond funds and short-term funds to reflect the Adviser's market outlook, which is primarily focused on the intermediate term.
• The Adviser may also make active asset allocations within other asset classes (such as commodities, high yield debt (also referred to as junk bonds), floating rate debt, real estate debt, and emerging markets debt) from 0% to 10% of the fund's total assets individually, but no more than 25% in aggregate within those other asset classes. Emerging markets include countries that have an emerging stock market as defined by MSCI, countries or markets with low- to middle-income economies as classified by the World Bank, and other countries or markets that the Adviser identifies as having similar emerging markets characteristics.
• Fidelity® Sustainable Funds employ sustainable investing exclusion criteria to avoid investments in issuers that are directly engaged in, and/or derive significant revenue from, certain industries. Please see "Fund Basics - Investment Details - Description of Underlying Fidelity® Funds" for additional information.

Principal Investment Risks

Shareholders should consider that no target date fund is intended as a complete retirement program and there is no guarantee that any single fund will provide sufficient retirement income at or through your retirement. The fund's share price fluctuates, which means you could lose money by investing in the fund, including losses near, at or after the target retirement date.

• Sustainability Risk.

The Adviser's adherence to its ESG ratings process may affect exposure to certain companies, sectors, regions, and countries and may affect performance depending on whether such investments are in or out of favor.

• Asset Allocation Risk.

The fund is subject to risks resulting from the Adviser's asset allocation decisions. The selection of underlying funds and the allocation of the fund's assets among various asset classes could cause the fund to lose value or its results to lag relevant benchmarks or other funds with similar objectives. In addition, the fund's active asset allocation strategy may cause the fund to have a risk profile different than that portrayed above from time to time and may increase losses.

• Investing in Other Funds.

The fund bears all risks of investment strategies employed by the underlying funds, including the risk that the underlying funds will not meet their investment objectives.

• Stock Market Volatility.

Stock markets are volatile and can decline significantly in response to adverse issuer, political, regulatory, market, or economic developments. Different parts of the market, including different market sectors, and different types of securities can react differently to these developments.

• Interest Rate Changes.

Interest rate increases can cause the price of a debt security to decrease.

• Foreign Exposure.

Foreign markets, particularly emerging markets, can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, market, or economic developments and can perform differently from the U.S. market. The extent of economic development; political stability; market depth, infrastructure, and capitalization; and regulatory oversight can be less than in more developed markets. Emerging markets typically have less established legal, accounting and financial reporting systems than those in more developed markets, which may reduce the scope or quality of financial information available to investors. Emerging markets can be subject to greater social, economic, regulatory, and political uncertainties and can be extremely volatile. Foreign exchange rates also can be extremely volatile.

• Industry Exposure.

Market conditions, interest rates, and economic, regulatory, or financial developments could significantly affect a single industry or group of related industries.

• Prepayment.

The ability of an issuer of a debt security to repay principal prior to a security's maturity can cause greater price volatility if interest rates change.

• Issuer-Specific Changes.

The value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole. Changes in the financial condition of an issuer or counterparty (e.g., broker-dealer or other borrower in a securities lending transaction) can increase the risk of default by an issuer or counterparty, which can affect a security's or instrument's value or result in delays in recovering securities and/or capital from a counterparty. A decline in the credit quality of an issuer or a provider of credit support or a maturity-shortening structure for a security can cause the price of a security to decrease.

Lower-quality debt securities (those of less than investment-grade quality, also referred to as high yield debt securities or junk bonds) including floating rate loans and certain types of other securities involve greater risk of default or price changes due to changes in the credit quality of the issuer. The value of lower-quality debt securities can be more volatile due to increased sensitivity to adverse issuer, political, regulatory, market, or economic developments and can be difficult to resell.

• Correlation to Index.

The performance of an underlying index fund and its index may vary somewhat due to factors such as fees and expenses of the underlying fund, transaction costs, sample selection, regulatory restrictions, and timing differences associated with additions to and deletions from the index. Errors in the construction or calculation of the index may occur from time to time and may not be identified and corrected for some period of time, which may have an adverse impact on an underlying fund and its shareholders.

• Passive Management Risk.

Some of the underlying funds in which the fund invests are managed with a passive investment strategy, attempting to track the performance of an unmanaged index of securities, regardless of the current or projected performance of an underlying fund's index or of the actual securities included in the index. This differs from an actively managed fund, which typically seeks to outperform a benchmark index. As a result, the performance of these underlying funds could be lower than actively managed funds that may shift their portfolio assets to take advantage of market opportunities or lessen the impact of a market decline or a decline in the value of one or more issuers. An underlying index fund may be concentrated to approximately the same extent that its index concentrates in the securities of issuers in a particular industry or group of industries.

• Leverage Risk.

Leverage can increase market exposure, magnify investment risks, and cause losses to be realized more quickly.

• Inflation-Protected Debt Exposure.

Increases in real interest rates can cause the price of inflation-protected debt securities to decrease. Interest payments on inflation-protected debt securities can be unpredictable.

• Quantitative Investing.

Securities selected using quantitative analysis can perform differently from the market as a whole as a result of the factors used in the analysis, the weight placed on each factor, and changes in the factors' historical trends.

An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.You could lose money by investing in the fund.

Let's say, hypothetically, that the annual return for shares of the fund is 5% and that the fees and the annual operating expenses for shares of the fund are exactly as described in the fee table. This example illustrates the effect of fees and expenses, but is not meant to suggest actual or expected fees and expenses or returns, all of which may vary. For every $10,000 you invested, here's how much you would pay in total expenses if you sell all of your shares at the end of each time period indicated and if you hold your shares:

Portfolio Turnover

The fund will not incur transaction costs, such as commissions, when it buys and sells shares of underlying Fidelity® funds (or "turns over" its portfolio), but it could incur transaction costs if it were to buy and sell other types of securities directly. If the fund were to buy and sell other types of securities directly, a higher portfolio turnover rate could indicate higher transaction costs and could result in higher taxes when fund shares are held in a taxable account. Such costs, if incurred, would not be reflected in annual operating expenses or in the example and would affect the fund's performance. For the period from May 11, 2023 to March 31, 2024, the fund's portfolio turnover rate was 29% (annualized) of the average value of its portfolio.

Principal Investment Strategies

• Investing at least 80% of assets in underlying funds that are (i) Fidelity® funds that invest in securities of issuers that Fidelity Management & Research Company LLC (FMR) (the Adviser) believes have proven or improving sustainability practices or positive environmental, social and governance (ESG) characteristics (Fidelity® Sustainable Funds), (ii) Fidelity index funds that track an ESG Index (Fidelity® Sustainable Index Funds), and (iii) Fidelity® funds that do not have a principal ESG investment strategy but invest at least 80% of assets in U.S. and international sovereign or government-related debt securities that the Fidelity® Sustainable Target Date Fund Adviser believes have positive ESG characteristics (Fidelity® Traditional Funds) (collectively, underlying Fidelity® Funds).
• Evaluating each security in which a Fidelity® Traditional Fund invests to determine whether 80% of assets are invested in sovereign or government-related debt securities whose issuers have positive ESG characteristics by considering the sustainability practices of the country or other issues based on an evaluation of such issuer's individual ESG profile using the Adviser's proprietary ESG ratings process.
• The Adviser's proprietary ESG ratings process evaluates the current state of an issuer's sustainability practices using a data-driven framework that includes both proprietary and third-party data, and also provides a qualitative forward-looking assessment of an issuer's sustainability outlook provided by the Adviser's fundamental research analysts and ESG team.
• Allocating assets according to a stable neutral asset allocation strategy (approximately 11% in U.S. equity funds, 8% in international equity funds, 43% in U.S. investment grade bond funds, 5% in international bond funds, 3% in long-term treasury bond funds, 0% in long-term inflation-protected bond funds, 20% in short-term inflation protected bond funds, and 10% in short-term funds). The Adviser may modify the fund's neutral asset allocations from time to time when in the interests of shareholders.
• Buying and selling futures contracts (both long and short positions) in an effort to manage cash flows efficiently, remain fully invested, or facilitate asset allocation.
• Allocating assets among underlying Fidelity® funds and futures according to a stable neutral asset allocation of approximately:

	U.S. Equity Funds 11%
	International Equity Funds 8%
	International Bond Funds 5%
	U.S. Investment Grade Bond Funds 43%
	Long-Term Treasury Bond Funds 3%
	Long-Term Inflation-Protected Bond Funds 0%
	Short-Term Inflation-Protected Bond Funds 20%
	Short-Term Funds 10%

* The Adviser may change these percentages over time. As a result of the active asset allocation strategy (discussed below), actual allocations may differ from the neutral allocations above. The allocation percentages may not add to 100% due to rounding.

• The Adviser, under normal market conditions, will use an active asset allocation strategy to increase or decrease asset class exposures relative to the neutral asset allocations reflected above by up to 10% for equity funds, bond funds and short-term funds to reflect the Adviser's market outlook, which is primarily focused on the intermediate term.
• The Adviser may also make active asset allocations within other asset classes (such as commodities, high yield debt (also referred to as junk bonds), floating rate debt, real estate debt, and emerging markets debt) from 0% to 10% of the fund's total assets individually, but no more than 25% in aggregate within those other asset classes. Emerging markets include countries that have an emerging stock market as defined by MSCI, countries or markets with low- to middle-income economies as classified by the World Bank, and other countries or markets that the Adviser identifies as having similar emerging markets characteristics.
• Fidelity® Sustainable Funds employ sustainable investing exclusion criteria to avoid investments in issuers that are directly engaged in, and/or derive significant revenue from, certain industries.

Principal Investment Risks

Shareholders should consider that no target date fund is intended as a complete retirement program and there is no guarantee that any single fund will provide sufficient retirement income at or through your retirement. The fund's share price fluctuates, which means you could lose money by investing in the fund, including losses near, at or after the target retirement date.

• Sustainability Risk.

The Adviser's adherence to its ESG ratings process may affect exposure to certain companies, sectors, regions, and countries and may affect performance depending on whether such investments are in or out of favor.

• Asset Allocation Risk.

The fund is subject to risks resulting from the Adviser's asset allocation decisions. The selection of underlying funds and the allocation of the fund's assets among various asset classes could cause the fund to lose value or its results to lag relevant benchmarks or other funds with similar objectives. In addition, the fund's active asset allocation strategy may cause the fund to have a risk profile different than that portrayed above from time to time and may increase losses.

• Investing in Other Funds.

The fund bears all risks of investment strategies employed by the underlying funds, including the risk that the underlying funds will not meet their investment objectives.

• Stock Market Volatility.

Stock markets are volatile and can decline significantly in response to adverse issuer, political, regulatory, market, or economic developments. Different parts of the market, including different market sectors, and different types of securities can react differently to these developments.

• Interest Rate Changes.

Interest rate increases can cause the price of a debt security to decrease.

• Foreign Exposure.

Foreign markets, particularly emerging markets, can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, market, or economic developments and can perform differently from the U.S. market. The extent of economic development; political stability; market depth, infrastructure, and capitalization; and regulatory oversight can be less than in more developed markets. Emerging markets typically have less established legal, accounting and financial reporting systems than those in more developed markets, which may reduce the scope or quality of financial information available to investors. Emerging markets can be subject to greater social, economic, regulatory, and political uncertainties and can be extremely volatile. Foreign exchange rates also can be extremely volatile.

• Industry Exposure.

Market conditions, interest rates, and economic, regulatory, or financial developments could significantly affect a single industry or group of related industries.

• Prepayment.

The ability of an issuer of a debt security to repay principal prior to a security's maturity can cause greater price volatility if interest rates change.

• Issuer-Specific Changes.

The value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole. Changes in the financial condition of an issuer or counterparty (e.g., broker-dealer or other borrower in a securities lending transaction) can increase the risk of default by an issuer or counterparty, which can affect a security's or instrument's value or result in delays in recovering securities and/or capital from a counterparty. A decline in the credit quality of an issuer or a provider of credit support or a maturity-shortening structure for a security can cause the price of a security to decrease.

Lower-quality debt securities (those of less than investment-grade quality, also referred to as high yield debt securities or junk bonds) including floating rate loans and certain types of other securities involve greater risk of default or price changes due to changes in the credit quality of the issuer. The value of lower-quality debt securities can be more volatile due to increased sensitivity to adverse issuer, political, regulatory, market, or economic developments and can be difficult to resell.

• Correlation to Index.

The performance of an underlying index fund and its index may vary somewhat due to factors such as fees and expenses of the underlying fund, transaction costs, sample selection, regulatory restrictions, and timing differences associated with additions to and deletions from the index. Errors in the construction or calculation of the index may occur from time to time and may not be identified and corrected for some period of time, which may have an adverse impact on an underlying fund and its shareholders.

• Passive Management Risk.

Some of the underlying funds in which the fund invests are managed with a passive investment strategy, attempting to track the performance of an unmanaged index of securities, regardless of the current or projected performance of an underlying fund's index or of the actual securities included in the index.

Fund Summary

Fund/Class:

Fidelity® Sustainable Target Date Income Fund

/K

Investment Objective

Fidelity® Sustainable Target Date Income Fund seeks high current income and, as a secondary objective, capital appreciation.

Fee Table

The following table describes the fees and expenses that may be incurred when you buy, hold, and sell shares of the fund. In addition to the fees and expenses described below, your broker may also require you to pay other fees, such as brokerage commissions on purchases and sales of certain classes of shares of the fund and other fees to financial intermediaries, which are not reflected in the tables and examples below.

Shareholder fees

(fees paid directly from your investment) None

Annual Operating Expenses

(expenses that you pay each year as a % of the value of your investment)

Management fee	0.31%A
Distribution and/or Service (12b-1) fees	None
Other expenses	0.00%
Total annual operating expenses	0.31%A

AAdjusted to reflect current fees.

This example helps compare the cost of investing in the fund with the cost of investing in other funds.

Let's say, hypothetically, that the annual return for shares of the fund is 5% and that the fees and the annual operating expenses for shares of the fund are exactly as described in the fee table. This example illustrates the effect of fees and expenses, but is not meant to suggest actual or expected fees and expenses or returns, all of which may vary. For every $10,000 you invested, here's how much you would pay in total expenses if you sell all of your shares at the end of each time period indicated:

1 year	$	32
3 years	$	100
5 years	$	174
10 years	$	393

Portfolio Turnover

The fund will not incur transaction costs, such as commissions, when it buys and sells shares of underlying Fidelity® funds (or "turns over" its portfolio), but it could incur transaction costs if it were to buy and sell other types of securities directly. If the fund were to buy and sell other types of securities directly, a higher portfolio turnover rate could indicate higher transaction costs and could result in higher taxes when fund shares are held in a taxable account. Such costs, if incurred, would not be reflected in annual operating expenses or in the example and would affect the fund's performance. For the period from May 11, 2023 to March 31, 2024, the fund's portfolio turnover rate was 29% (annualized) of the average value of its portfolio.

Principal Investment Strategies

• Investing at least 80% of assets in underlying funds that are (i) Fidelity® funds that invest in securities of issuers that Fidelity Management & Research Company LLC (FMR) (the Adviser) believes have proven or improving sustainability practices or positive environmental, social and governance (ESG) characteristics (Fidelity® Sustainable Funds), (ii) Fidelity index funds that track an ESG Index (Fidelity® Sustainable Index Funds), and (iii) Fidelity® funds that do not have a principal ESG investment strategy but invest at least 80% of assets in U.S. and international sovereign or government-related debt securities that the Fidelity® Sustainable Target Date Fund Adviser believes have positive ESG characteristics (Fidelity® Traditional Funds) (collectively, underlying Fidelity® Funds).
• Evaluating each security in which a Fidelity® Traditional Fund invests to determine whether 80% of assets are invested in sovereign or government-related debt securities whose issuers have positive ESG characteristics by considering the sustainability practices of the country or other issues based on an evaluation of such issuer's individual ESG profile using the Adviser's proprietary ESG ratings process.
• The Adviser's proprietary ESG ratings process evaluates the current state of an issuer's sustainability practices using a data-driven framework that includes both proprietary and third-party data, and also provides a qualitative forward-looking assessment of an issuer's sustainability outlook provided by the Adviser's fundamental research analysts and ESG team.
• Allocating assets according to a stable neutral asset allocation strategy (approximately 11% in U.S. equity funds, 8% in international equity funds, 43% in U.S. investment grade bond funds, 5% in international bond funds, 3% in long-term treasury bond funds, 0% in long-term inflation-protected bond funds, 20% in short-term inflation protected bond funds, and 10% in short-term funds). The Adviser may modify the fund's neutral asset allocations from time to time when in the interests of shareholders.
• Buying and selling futures contracts (both long and short positions) in an effort to manage cash flows efficiently, remain fully invested, or facilitate asset allocation.
• Allocating assets among underlying Fidelity® funds and futures according to a stable neutral asset allocation of approximately:

	U.S. Equity Funds 11%
	International Equity Funds 8%
	International Bond Funds 5%
	U.S. Investment Grade Bond Funds 43%
	Long-Term Treasury Bond Funds 3%
	Long-Term Inflation-Protected Bond Funds 0%
	Short-Term Inflation-Protected Bond Funds 20%
	Short-Term Funds 10%

* The Adviser may change these percentages over time. As a result of the active asset allocation strategy (discussed below), actual allocations may differ from the neutral allocations above. The allocation percentages may not add to 100% due to rounding.

• The Adviser, under normal market conditions, will use an active asset allocation strategy to increase or decrease asset class exposures relative to the neutral asset allocations reflected above by up to 10% for equity funds, bond funds and short-term funds to reflect the Adviser's market outlook, which is primarily focused on the intermediate term.
• The Adviser may also make active asset allocations within other asset classes (such as commodities, high yield debt (also referred to as junk bonds), floating rate debt, real estate debt, and emerging markets debt) from 0% to 10% of the fund's total assets individually, but no more than 25% in aggregate within those other asset classes. Emerging markets include countries that have an emerging stock market as defined by MSCI, countries or markets with low- to middle-income economies as classified by the World Bank, and other countries or markets that the Adviser identifies as having similar emerging markets characteristics.
• Fidelity® Sustainable Funds employ sustainable investing exclusion criteria to avoid investments in issuers that are directly engaged in, and/or derive significant revenue from, certain industries. Please see "Fund Basics - Investment Details - Description of Underlying Fidelity® Funds" for additional information.

Principal Investment Risks

Shareholders should consider that no target date fund is intended as a complete retirement program and there is no guarantee that any single fund will provide sufficient retirement income at or through your retirement. The fund's share price fluctuates, which means you could lose money by investing in the fund, including losses near, at or after the target retirement date.

• Sustainability Risk.

The Adviser's adherence to its ESG ratings process may affect exposure to certain companies, sectors, regions, and countries and may affect performance depending on whether such investments are in or out of favor.

• Asset Allocation Risk.

The fund is subject to risks resulting from the Adviser's asset allocation decisions. The selection of underlying funds and the allocation of the fund's assets among various asset classes could cause the fund to lose value or its results to lag relevant benchmarks or other funds with similar objectives. In addition, the fund's active asset allocation strategy may cause the fund to have a risk profile different than that portrayed above from time to time and may increase losses.

• Investing in Other Funds.

The fund bears all risks of investment strategies employed by the underlying funds, including the risk that the underlying funds will not meet their investment objectives.

• Stock Market Volatility.

Stock markets are volatile and can decline significantly in response to adverse issuer, political, regulatory, market, or economic developments. Different parts of the market, including different market sectors, and different types of securities can react differently to these developments.

• Interest Rate Changes.

Interest rate increases can cause the price of a debt security to decrease.

• Foreign Exposure.

Foreign markets, particularly emerging markets, can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, market, or economic developments and can perform differently from the U.S. market. The extent of economic development; political stability; market depth, infrastructure, and capitalization; and regulatory oversight can be less than in more developed markets. Emerging markets typically have less established legal, accounting and financial reporting systems than those in more developed markets, which may reduce the scope or quality of financial information available to investors. Emerging markets can be subject to greater social, economic, regulatory, and political uncertainties and can be extremely volatile. Foreign exchange rates also can be extremely volatile.

• Industry Exposure.

Market conditions, interest rates, and economic, regulatory, or financial developments could significantly affect a single industry or group of related industries.

• Prepayment.

The ability of an issuer of a debt security to repay principal prior to a security's maturity can cause greater price volatility if interest rates change.

• Issuer-Specific Changes.

The value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole. Changes in the financial condition of an issuer or counterparty (e.g., broker-dealer or other borrower in a securities lending transaction) can increase the risk of default by an issuer or counterparty, which can affect a security's or instrument's value or result in delays in recovering securities and/or capital from a counterparty. A decline in the credit quality of an issuer or a provider of credit support or a maturity-shortening structure for a security can cause the price of a security to decrease.

Lower-quality debt securities (those of less than investment-grade quality, also referred to as high yield debt securities or junk bonds) including floating rate loans and certain types of other securities involve greater risk of default or price changes due to changes in the credit quality of the issuer. The value of lower-quality debt securities can be more volatile due to increased sensitivity to adverse issuer, political, regulatory, market, or economic developments and can be difficult to resell.

• Correlation to Index.

The performance of an underlying index fund and its index may vary somewhat due to factors such as fees and expenses of the underlying fund, transaction costs, sample selection, regulatory restrictions, and timing differences associated with additions to and deletions from the index. Errors in the construction or calculation of the index may occur from time to time and may not be identified and corrected for some period of time, which may have an adverse impact on an underlying fund and its shareholders.

• Passive Management Risk.

Some of the underlying funds in which the fund invests are managed with a passive investment strategy, attempting to track the performance of an unmanaged index of securities, regardless of the current or projected performance of an underlying fund's index or of the actual securities included in the index. This differs from an actively managed fund, which typically seeks to outperform a benchmark index. As a result, the performance of these underlying funds could be lower than actively managed funds that may shift their portfolio assets to take advantage of market opportunities or lessen the impact of a market decline or a decline in the value of one or more issuers. An underlying index fund may be concentrated to approximately the same extent that its index concentrates in the securities of issuers in a particular industry or group of industries.

• Leverage Risk.

Leverage can increase market exposure, magnify investment risks, and cause losses to be realized more quickly.

• Inflation-Protected Debt Exposure.

Increases in real interest rates can cause the price of inflation-protected debt securities to decrease. Interest payments on inflation-protected debt securities can be unpredictable.

• Quantitative Investing.

Securities selected using quantitative analysis can perform differently from the market as a whole as a result of the factors used in the analysis, the weight placed on each factor, and changes in the factors' historical trends.

An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.You could lose money by investing in the fund.
