Fees and Expenses

The following table describes the fees and expenses you may pay if you buy and hold Investor Shares of the Fund.

Shareholder Fees (Fees paid directly from your investment)

Shareholder Fees (Vanguard PRIMECAP Fund Participant) Vanguard PRIMECAP Fund	Vanguard PRIMECAP Fund - Investor Shares
Sales charge (load) imposed on purchases	none
Purchase Fee	none
Sales charge (load) imposed on reinvested dividends	none
Redemption Fee	1.00%

Annual Fund Operating Expenses (Expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses (Vanguard PRIMECAP Fund Participant) Vanguard PRIMECAP Fund	Vanguard PRIMECAP Fund - Investor Shares
Management Expenses	0.43%
12b-1 Distribution Fee	none
Other Expenses	0.02%
Total Annual Fund Operating Expenses	0.45%

Example

The following example is intended to help you compare the cost of investing in the Fund's Investor Shares with the cost of investing in other mutual funds. It illustrates the hypothetical expenses that you would incur over various periods if you invest $10,000 in the Fund's shares. This example assumes that the Shares provide a return of 5% a year and that operating expenses remain as stated in the preceding table. The results apply whether or not you redeem your investment at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example, No Redemption (Vanguard PRIMECAP Fund Participant) Vanguard PRIMECAP Fund (USD $)	1 YEAR	3 YEAR	5 YEAR	10 YEAR
Vanguard PRIMECAP Fund - Investor Shares	46	144	252	567

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 more taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense example, reduce the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 8%.

Primary Investment Strategies

The Fund invests in stocks considered to have above-average earnings growth potential that is not reflected in their current market prices. The Fund's portfolio consists predominantly of large- and mid-capitalization stocks.

Primary Risks

An investment in the Fund could lose money over short or even long periods. You should expect the Fund's share price and total return to fluctuate within a wide range, like the fluctuations of the overall stock market. The Fund's performance could be hurt by:

Stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices.

Asset concentration risk, which is the chance that the Fund's performance may be adversely affected by the poor performance of relatively few stocks as compared with other mutual funds. The Fund may concentrate a large portion of its assets in relatively few holdings within the universe of undervalued stocks. As a result, the volatility experienced by the Fund may be greater than the overall volatility of the stock market.

Investment style risk, which is the chance that returns from large- and mid-capitalization growth stocks will trail returns from the overall stock market. Historically, mid-cap stocks have been more volatile in price than the large-cap stocks that dominate the overall market, and they often perform quite differently.

Manager risk, which is the chance that poor security selection or focus on securities in a particular sector, category, or group of companies will cause the Fund to underperform relevant benchmarks or other funds with a similar investment objective.

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.

Actual after-tax returns depend on your tax situation and may differ from those shown in the preceding table. When after-tax returns are calculated, it is assumed that the shareholder was in the highest individual federal marginal income tax bracket at the time of each distribution of income or capital gains or upon redemption. State and local income taxes are not reflected in the calculations. Please note that after-tax returns are shown only for the Investor Shares and may differ for each share class. After-tax returns are not relevant for a shareholder who holds fund shares in a tax-deferred account, such as an individual retirement account or a 401(k) plan. Also, figures captioned Return After Taxes on Distributions and Sale of Fund Shares will be higher than other figures for the same period if a capital loss occurs upon redemption and results in an assumed tax deduction for the shareholder.

This example assumes that the Fund provides a return of 5% a year and that operating expenses of the Fund and its underlying funds remain as stated in the preceding table. The results apply whether or not you redeem your investment at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Vanguard Target Retirement 2005 Fund - Investor Shares	17	55	96	217

Portfolio Turnover

The Fund may pay transaction costs, such as purchase fees, 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 more taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense example, reduce the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 27%.

Primary Investment Strategies

The Fund invests in other Vanguard mutual funds according to an asset allocation strategy designed for investors who have retired and left the work force in 2005 (the target year) or within a few years thereof. The Fund is designed for an investor who plans to withdraw the value of an account in the Fund gradually after the target year. The Fund's asset allocation will become more conservative over time, meaning that the percentage of assets allocated to stocks will decrease while the percentage of assets allocated to bond and other fixed income investments will increase. Within seven years after 2005, the Fund's asset allocation should become similar to that of the Target Retirement Income Fund. As of September 30, 2011, the Fund's asset allocation among the underlying funds was as follows:

Vanguard Total Bond Market II Index Fund 44.8%

Vanguard Total Stock Market Index Fund 22.2%

Vanguard Inflation-Protected Securities Fund 19.0%

Vanguard Total International Stock Index Fund 9.5%

Vanguard Prime Money Market Fund 4.5%

At any given time, the Fund's asset allocation may be affected by a variety of factors, such as whether the underlying funds are accepting additional investments.

The Fund's indirect bond holdings are a diversified mix of short-, intermediate-, and long-term investment-grade, taxable U.S. government, U.S. agency, and corporate bonds; inflation-indexed bonds issued by the U.S. government; and mortgage-backed securities.

The Fund's indirect stock holdings consist substantially of large-capitalization U.S. stocks and, to a lesser extent, of mid- and small-cap U.S. stocks, as well as foreign stocks, including emerging markets.

Primary Risks

The Fund is subject to the risks associated with the stock and bond markets, any of which could cause an investor to lose money. An investment in the Fund is not guaranteed. An investor may experience losses, including losses near, at, or after the target year. There is no guarantee that the Fund will provide adequate income at or after the target year. However, because bonds usually are less volatile than stocks, and because the Fund currently invests approximately half of its assets in fixed income securities, the Fund's overall level of risk should be moderate.

With approximately 68% of its assets currently allocated to bonds and money market instruments, the Fund is proportionately subject to bond risks: interest rate risk, which is the chance that bond prices overall will decline because of rising interest rates; income risk, which is the chance that an underlying fund's income will decline because of falling interest rates or declining inflation; credit risk, which is the chance that the issuer of a security will fail to pay interest and principal in a timely manner, or that negative perceptions of the issuer's ability to make such payments will cause the price of that security to decline, thus reducing an underlying fund's return; and call risk, which is the chance that during periods of falling interest rates, issuers of callable bonds may call (redeem) securities with higher coupons or interest rates before their maturity dates. An underlying fund would then lose any price appreciation above the bond's call price and would be forced to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the underlying fund's income. For mortgage-backed securities, this risk is known as prepayment risk.

With approximately 32% of its assets currently allocated to stocks, the Fund is proportionately subject to stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices. The Fund is also subject to the following risks associated with investments in foreign stocks: country/regional risk, which is the chance that world events-such as political upheaval, financial troubles, or natural disasters-will adversely affect the value of companies in any one country or region; and currency risk, which is the chance that the value of a foreign investment, measured in U.S. dollars, will decrease because of unfavorable changes in currency exchange rates. Country/regional risk and currency risk are especially high in emerging markets.

The Fund is also subject to asset allocation risk, which is the chance that the selection of underlying funds, and the allocation of assets to them, will cause the Fund to underperform other funds with a similar investment objective.

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.

Actual after-tax returns depend on your tax situation and may differ from those shown in the preceding table. When after-tax returns are calculated, it is assumed that the shareholder was in the highest individual federal marginal income tax bracket at the time of each distribution of income or capital gains or upon redemption. State and local income taxes are not reflected in the calculations. Please note that after-tax returns are not relevant for a shareholder who holds fund shares in a tax-deferred account, such as an individual retirement account or a 401(k) plan. Also, figures captioned Return After Taxes on Distributions and Sale of Fund Shares will be higher than other figures for the same period if a capital loss occurs upon redemption and results in an assumed tax deduction for the shareholder.

Example

The following example is intended to help you compare the cost of investing in the Fund (based on the fees and expenses of the Acquired Funds) with the cost of investing in other mutual funds. It illustrates the hypothetical expenses that you would incur over various periods if you invest $10,000 in the Fund's shares. This example assumes that the Fund provides a return of 5% a year and that operating expenses of the Fund and its underlying funds remain as stated in the preceding table. The results apply whether or not you redeem your investment at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example, No Redemption (Vanguard Target Retirement 2010 Fund Participant) Vanguard Target Retirement 2010 Fund (USD $)	1 YEAR	3 YEAR	5 YEAR	10 YEAR
Vanguard Target Retirement 2010 Fund - Investor Shares	17	55	96	217

Portfolio Turnover

The Fund may pay transaction costs, such as purchase fees, 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 more taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense example, reduce the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 27%.

Primary Investment Strategies

The Fund invests in other Vanguard mutual funds according to an asset allocation strategy designed for investors planning to retire and leave the work force in or within a few years of 2010 (the target year). The Fund is designed for an investor who plans to withdraw the value of an account in the Fund gradually after the target year. The Fund's asset allocation will become more conservative over time, meaning that the percentage of assets allocated to stocks will decrease while the percentage of assets allocated to bonds and other fixed income investments will increase. Within seven years after 2010, the Fund's asset allocation should become similar to that of the Target Retirement Income Fund. As of September 30, 2011, the Fund's asset allocation among the underlying funds was as follows:

Vanguard Total Bond Market II Index Fund 41.4%

Vanguard Total Stock Market Index Fund 32.0%

Vanguard Total International Stock Index Fund 13.9%

Vanguard Inflation-Protected Securities Fund 11.8%

Vanguard Prime Money Market Fund 0.9%

At any given time, the Fund's asset allocation may be affected by a variety of factors, such as whether the underlying funds are accepting additional investments.

The Fund's indirect stock holdings consist substantially of large-capitalization U.S. stocks and, to a lesser extent, of mid- and small-cap U.S. stocks, as well as foreign stocks, including emerging markets.

The Fund's indirect bond holdings are a diversified mix of short-, intermediate-, and long-term investment-grade, taxable U.S. government, U.S. agency, and corporate bonds; inflation-indexed bonds issued by the U.S. government; and mortgage-backed securities.

Primary Risks

The Fund is subject to the risks associated with the stock and bond markets, any of which could cause an investor to lose money. An investment in the Fund is not guaranteed. An investor may experience losses, including losses near, at, or after the target year. There is no guarantee that the Fund will provide adequate income at or after the target year. However, because bonds usually are less volatile than stocks, and because the Fund currently invests a significant portion of its assets in fixed income securities, the Fund's overall level of risk should be moderate.

With approximately 46% of its assets currently allocated to stocks, the Fund is proportionately subject to stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices. The Fund is also subject to the following risks associated with investments in foreign stocks: country/regional risk, which is the chance that world events-such as political upheaval, financial troubles, or natural disasters-will adversely affect the value of companies in any one country or region; and currency risk, which is the chance that the value of a foreign investment, measured in U.S. dollars, will decrease because of unfavorable changes in currency exchange rates. Country/regional risk and currency risk are especially high in emerging markets.

With approximately 54% of its assets currently allocated to bonds and money market instruments, the Fund is proportionately subject to bond risks: interest rate risk, which is the chance that bond prices overall will decline because of rising interest rates; income risk, which is the chance that the underlying fund's income will decline because of falling interest rates or declining inflation; credit risk, which is the chance that a bond issuer will fail to pay interest and principal in a timely manner, or that negative perceptions of the issuer's ability to make such payments will cause the price of that bond to decline, thus reducing the underlying fund's return; and call risk, which is the chance that during periods of falling interest rates, issuers of callable bonds may call (redeem) securities with higher coupons or interest rates before their maturity dates. An underlying fund would then lose any price appreciation above the bond's call price and would be forced to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the underlying fund's income. For mortgage-backed securities, this risk is known as prepayment risk.

The Fund is also subject to asset allocation risk, which is the chance that the selection of underlying funds, and the allocation of assets to them, will cause the Fund to underperform other funds with a similar investment objective.

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.

Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices. The Fund is also subject to the following risks associated with investments in foreign stocks: country/regional risk, which is the chance that world events-such as political upheaval, financial troubles, or natural disasters-will adversely affect the value of companies in any one country or region; and currency risk, which is the chance that the value of a foreign investment, measured in U.S. dollars, will decrease because of unfavorable changes in currency exchange rates. Country/regional risk and currency risk are especially high in emerging markets.

With approximately 43% of its assets currently allocated to bonds, the Fund is proportionately subject to bond risks: interest rate risk, which is the chance that bond prices overall will decline because of rising interest rates; income risk, which is the chance that the underlying fund's income will decline because of falling interest rates; credit risk, which is the chance that a bond issuer will fail to pay interest and principal in a timely manner, or that negative perceptions of the issuer's ability to make such payments will cause the price of that bond to decline, thus reducing the underlying fund's return; and call risk, which is the chance that during periods of falling interest rates, issuers of callable bonds may call (redeem) securities with higher coupons or interest rates before their maturity dates. The underlying fund would then lose any price appreciation above the bond's call price and would be forced to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the underlying fund's income. For mortgage-backed securities, this risk is known as prepayment risk.

The Fund is also subject to asset allocation risk, which is the chance that the selection of underlying funds, and the allocation of assets to them, will cause the Fund to underperform other funds with a similar investment objective.

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.

Actual after-tax returns depend on your tax situation and may differ from those shown in the preceding table. When after-tax returns are calculated, it is assumed that the shareholder was in the highest individual federal marginal income tax bracket at the time of each distribution of income or capital gains or upon redemption. State and local income taxes are not reflected in the calculations. Please note that after-tax returns are not relevant for a shareholder who holds fund shares in a tax-deferred account, such as an individual retirement account or a 401(k) plan. Also, figures captioned Return After Taxes on Distributions and Sale of Fund Shares will be higher than other figures for the same period if a capital loss occurs upon redemption and results in an assumed tax deduction for the shareholder.

The following example is intended to help you compare the cost of investing in the Fund (based on the fees and expenses of the Acquired Funds) with the cost of investing in other mutual funds. It illustrates the hypothetical expenses that you would incur over various periods if you invest $10,000 in the Fund's shares. This example assumes that the Fund provides a return of 5% a year and that operating expenses of the Fund and its underlying funds remain as stated in the preceding table. The results apply whether or not you redeem your investment at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Vanguard Target Retirement 2020 Fund - Investor Shares	17	55	96	217

Portfolio Turnover

The Fund may pay transaction costs, such as purchase fees, 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 more taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense example, reduce the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 23%.

Primary Investment Strategies

The Fund invests in other Vanguard mutual funds according to an asset allocation strategy designed for investors planning to retire and leave the work force in or within a few years of 2020 (the target year). The Fund is designed for an investor who plans to withdraw the value of an account in the Fund gradually after the target year. The Fund's asset allocation will become more conservative over time, meaning that the percentage of assets allocated to stocks will decrease while the percentage of assets allocated to bonds and other fixed income investments will increase. Within seven years after 2020, the Fund's asset allocation should become similar to that of the Target Retirement Income Fund. As of September 30, 2011, the Fund's asset allocation among the underlying funds was as follows:

Vanguard Total Stock Market Index Fund 45.6%

Vanguard Total Bond Market II Index Fund 34.9%

Vanguard Total International Stock Index Fund 19.5%

At any given time, the Fund's asset allocation may be affected by a variety of factors, such as whether the underlying funds are accepting additional investments.

The Fund's indirect stock holdings consist substantially of large-capitalization U.S. stocks and, to a lesser extent, of mid- and small-cap U.S. stocks, as well as foreign stocks, including emerging markets.

The Fund's indirect bond holdings are a diversified mix of short-, intermediate-, and long-term investment-grade, taxable U.S. government, U.S. agency, and corporate bonds, as well as mortgage-backed securities.

Primary Risks

The Fund is subject to the risks associated with the stock and bond markets, any of which could cause an investor to lose money. An investment in the Fund is not guaranteed. An investor may experience losses, including losses near, at, or after the target year. There is no guarantee that the Fund will provide adequate income at or after the target year. Because stocks usually are more volatile than bonds, and because the Fund currently invests more of its assets in stocks, the Fund's overall level of risk should be higher than that of funds that invest the majority of their assets in bonds; however, the level of risk should be lower than that of funds investing entirely in stocks.

With approximately 65% of its assets currently allocated to stocks, the Fund is proportionately subject to stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices. The Fund is also subject to the following risks associated with investments in foreign stocks: country/regional risk, which is the chance that world events-such as political upheaval, financial troubles, or natural disasters-will adversely affect the value of companies in any one country or region; and currency risk, which is the chance that the value of a foreign investment, measured in U.S. dollars, will decrease because of unfavorable changes in currency exchange rates.

This example assumes that the Fund provides a return of 5% a year and that operating expenses of the Fund and its underlying funds remain as stated in the preceding table. The results apply whether or not you redeem your investment at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example, No Redemption (Vanguard Target Retirement 2025 Fund Retail) Vanguard Target Retirement 2025 Fund (USD $)	1 YEAR	3 YEAR	5 YEAR	10 YEAR
Vanguard Target Retirement 2025 Fund - Investor Shares	18	58	101	230

Portfolio Turnover

The Fund may pay transaction costs, such as purchase fees, 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 more taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense example, reduce the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 23%.

Primary Investment Strategies

The Fund invests in other Vanguard mutual funds according to an asset allocation strategy designed for investors planning to retire and leave the work force in or within a few years of 2025 (the target year). The Fund is designed for an investor who plans to withdraw the value of an account in the Fund gradually after the target year. The Fund's asset allocation will become more conservative over time, meaning that the percentage of assets allocated to stocks will decrease while the percentage of assets allocated to bonds and other fixed income investments will increase. Within seven years after 2025, the Fund's asset allocation should become similar to that of the Target Retirement Income Fund. As of September 30, 2011, the Fund's asset allocation among the underlying funds was as follows:

Vanguard Total Stock Market Index Fund 50.9%

Vanguard Total Bond Market II Index Fund 27.4%

Vanguard Total International Stock Index Fund 21.7%

At any given time, the Fund's asset allocation may be affected by a variety of factors, such as whether the underlying funds are accepting additional investments.

The Fund's indirect stock holdings consist substantially of large-capitalization U.S. stocks and, to a lesser extent, of mid- and small-cap U.S. stocks, as well as foreign stocks, including emerging markets.

The Fund's indirect bond holdings are a diversified mix of short-, intermediate-, and long-term investment-grade, taxable U.S. government, U.S. agency, and corporate bonds, as well as mortgage-backed securities.

Primary Risks

The Fund is subject to the risks associated with the stock and bond markets, any of which could cause an investor to lose money. An investment in the Fund is not guaranteed. An investor may experience losses, including losses near, at, or after the target year. There is no guarantee that the Fund will provide adequate income at or after the target year. Because stocks usually are more volatile than bonds, and because the Fund currently invests more of its assets in stocks, the Fund's overall level of risk should be higher than that of funds that invest the majority of their assets in bonds; however, the level of risk should be lower than that of funds investing entirely in stocks.

With approximately 73% of its assets currently allocated to stocks, the Fund is proportionately subject to stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices. The Fund is also subject to the following risks associated with investments in foreign stocks: country/regional risk, which is the chance that world events-such as political upheaval, financial troubles, or natural disasters-will adversely affect the value of companies in any one country or region; and currency risk, which is the chance that the value of a foreign investment, measured in U.S. dollars, will decrease because of unfavorable changes in currency exchange rates. Country/regional risk and currency risk are especially high in emerging markets.

With approximately 27% of its assets currently allocated to bonds, the Fund is proportionately subject to bond risks: interest rate risk, which is the chance that bond prices overall will decline because of rising interest rates; income risk, which is the chance that the underlying fund's income will decline because of falling interest rates; credit risk, which is the chance that a bond issuer will fail to pay interest and principal in a timely manner, or that negative perceptions of the issuer's ability to make such payments will cause the price of that bond to decline, thus reducing the underlying fund's return; and call risk, which is the chance that during periods of falling interest rates, issuers of callable bonds may call (redeem) securities with higher coupons or interest rates before their maturity dates. The underlying fund would then lose any price appreciation above the bond's call price and would be forced to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the underlying fund's income. For mortgage-backed securities, this risk is known as prepayment risk.

The Fund is also subject to asset allocation risk, which is the chance that the selection of underlying funds, and the allocation of assets to them, will cause the Fund to underperform other funds with a similar investment objective.

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.

Annual Total Returns

Actual after-tax returns depend on your tax situation and may differ from those shown in the preceding table. When after-tax returns are calculated, it is assumed that the shareholder was in the highest individual federal marginal income tax bracket at the time of each distribution of income or capital gains or upon redemption. State and local income taxes are not reflected in the calculations. Please note that after-tax returns are not relevant for a shareholder who holds fund shares in a tax-deferred account, such as an individual retirement account or a 401(k) plan. Also, figures captioned Return After Taxes on Distributions and Sale of Fund Shares will be higher than other figures for the same period if a capital loss occurs upon redemption and results in an assumed tax deduction for the shareholder.

Example

The following example is intended to help you compare the cost of investing in the Fund (based on the fees and expenses of the Acquired Funds) with the cost of investing in other mutual funds. It illustrates the hypothetical expenses that you would incur over various periods if you invest $10,000 in the Fund's shares. This example assumes that the Fund provides a return of 5% a year and that operating expenses of the Fund and its underlying funds remain as stated in the preceding table. The results apply whether or not you redeem your investment at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example, No Redemption (Vanguard Target Retirement 2035 Fund Retail) Vanguard Target Retirement 2035 Fund (USD $)	1 YEAR	3 YEAR	5 YEAR	10 YEAR
Vanguard Target Retirement 2035 Fund - Investor Shares	19	61	107	243

Portfolio Turnover

The Fund may pay transaction costs, such as purchase fees, 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 more taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense example, reduce the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 18%.

Primary Investment Strategies

The Fund invests in other Vanguard mutual funds according to an asset allocation strategy designed for investors planning to retire and leave the work force in or within a few years of 2035 (the target year). The Fund is designed for an investor who plans to withdraw the value of an account in the Fund gradually after the target year. The Fund's asset allocation will become more conservative over time, meaning that the percentage of assets allocated to stocks will decrease while the percentage of assets allocated to bonds and other fixed income investments will increase. Within seven years after 2035, the Fund's asset allocation should become similar to that of the Target Retirement Income Fund. As of September 30, 2011, the Fund's asset allocation among the underlying funds was as follows:

Vanguard Total Stock Market Index Fund 61.6%

Vanguard Total International Stock Index Fund 26.3%

Vanguard Total Bond Market II Index Fund 12.1%

At any given time, the Fund's asset allocation may be affected by a variety of factors, such as whether the underlying funds are accepting additional investments.

The Fund's indirect stock holdings consist substantially of large-capitalization U.S. stocks and, to a lesser extent, of mid- and small-cap U.S. stocks, as well as foreign stocks, including emerging markets.

The Fund's indirect bond holdings are a diversified mix of short-, intermediate-, and long-term investment-grade, taxable U.S. government, U.S. agency, and corporate bonds, as well as mortgage-backed securities.

Primary Risks

The Fund is subject to the risks associated with the stock and bond markets, any of which could cause an investor to lose money. An investment in the Fund is not guaranteed. An investor may experience losses, including losses near, at, or after the target year. There is no guarantee that the Fund will provide adequate income at or after the target year. Because stocks usually are more volatile than bonds, and because the Fund currently invests more of its assets in stocks, the Fund's overall level of risk should be higher than that of funds that invest the majority of their assets in bonds; however, the level of risk should be lower than that of funds investing entirely in stocks.

With approximately 88% of its assets currently allocated to stocks, the Fund is proportionately subject to stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices. The Fund is also subject to the following risks associated with investments in foreign stocks: country/regional risk, which is the chance that world events-such as political upheaval, financial troubles, or natural disasters-will adversely affect the value of companies in any one country or region; and currency risk, which is the chance that the value of a foreign investment, measured in U.S. dollars, will decrease because of unfavorable changes in currency exchange rates. Country/regional risk and currency risk are especially high in emerging markets.

With approximately 12% of its assets currently allocated to bonds, the Fund is proportionately subject to bond risks: interest rate risk, which is the chance that bond prices overall will decline because of rising interest rates; income risk, which is the chance that the underlying fund's income will decline because of falling interest rates; credit risk, which is the chance that a bond issuer will fail to pay interest and principal in a timely manner, or that negative perceptions of the issuer's ability to make such payments will cause the price of that bond to decline, thus reducing the underlying fund's return; and call risk, which is the chance that during periods of falling interest rates, issuers of callable bonds may call (redeem) securities with higher coupons or interest rates before their maturity dates. The underlying fund would then lose any price appreciation above the bond's call price and would be forced to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the underlying fund's income. For mortgage-backed securities, this risk is known as prepayment risk.

The Fund is also subject to asset allocation risk, which is the chance that the selection of underlying funds, and the allocation of assets to them, will cause the Fund to underperform other funds with a similar investment objective.

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.

Annual Total Returns

The following bar chart and table are intended to help you understand the risks of investing in the Fund. The bar chart shows how the performance of the Fund has varied from one calendar year to another over the periods shown. The table shows how the average annual total returns compare with those of relevant market indexes and a composite bond/stock index, which have investment characteristics similar to those of the Fund. Keep in mind that the Fund's past performance (before and after taxes) does not indicate how the Fund will perform in the future.

Actual after-tax returns depend on your tax situation and may differ from those shown in the preceding table. When after-tax returns are calculated, it is assumed that the shareholder was in the highest individual federal marginal income tax bracket at the time of each distribution of income or capital gains or upon redemption. State and local income taxes are not reflected in the calculations. Please note that after-tax returns are not relevant for a shareholder who holds fund shares in a tax-deferred account, such as an individual retirement account or a 401(k) plan. Also, figures captioned Return After Taxes on Distributions and Sale of Fund Shares will be higher than other figures for the same period if a capital loss occurs upon redemption and results in an assumed tax deduction for the shareholder.

The Fund is also subject to the following risks associated with investments in foreign stocks: country/regional risk, which is the chance that world events-such as political upheaval, financial troubles, or natural disasters-will adversely affect the value of companies in any one country or region; and currency risk, which is the chance that the value of a foreign investment, measured in U.S. dollars, will decrease because of unfavorable changes in currency exchange rates. Country/regional risk and currency risk are especially high in emerging markets.

With approximately 10% of its assets currently allocated to bonds, the Fund is proportionately subject to bond risks: interest rate risk, which is the chance that bond prices overall will decline because of rising interest rates; income risk, which is the chance that the underlying fund's income will decline because of falling interest rates; credit risk, which is the chance that a bond issuer will fail to pay interest and principal in a timely manner, or that negative perceptions of the issuer's ability to make such payments will cause the price of that bond to decline, thus reducing the underlying fund's return; and call risk, which is the chance that during periods of falling interest rates, issuers of callable bonds may call (redeem) securities with higher coupons or interest rates before their maturity dates. The underlying fund would then lose any price appreciation above the bond's call price and would be forced to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the underlying fund's income. For mortgage-backed securities, this risk is known as prepayment risk.

The Fund is also subject to asset allocation risk, which is the chance that the selection of underlying funds, and the allocation of assets to them, will cause the Fund to underperform other funds with a similar investment objective.

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.

Example

The following example is intended to help you compare the cost of investing in the Fund (based on the fees and expenses of the Acquired Funds) with the cost of investing in other mutual funds. It illustrates the hypothetical expenses that you would incur over various periods if you invest $10,000 in the Fund's shares. This example assumes that the Fund provides a return of 5% a year and that operating expenses of the Fund and its underlying funds remain as stated in the preceding table. The results apply whether or not you redeem your investment at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example, No Redemption (Vanguard Target Retirement 2045 Fund Retail) Vanguard Target Retirement 2045 Fund (USD $)	1 YEAR	3 YEAR	5 YEAR	10 YEAR
Vanguard Target Retirement 2045 Fund - Investor Shares	19	61	107	243

Portfolio Turnover

The Fund may pay transaction costs, such as purchase fees, 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 more taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense example, reduce the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 16%.

Primary Investment Strategies

The Fund invests in other Vanguard mutual funds according to an asset allocation strategy designed for investors planning to retire and leave the work force in or within a few years of 2045 (the target year). The Fund is designed for an investor who plans to withdraw the value of an account in the Fund gradually after the target year. The Fund's asset allocation will become more conservative over time, meaning that the percentage of assets allocated to stocks will decrease while the percentage of assets allocated to bonds and other fixed income investments will increase. Within seven years after 2045, the Fund's asset allocation should become similar to that of the Target Retirement Income Fund. As of September 30, 2011, the Fund's asset allocation among the underlying funds was as follows:

Vanguard Total Stock Market Index Fund 62.8%

Vanguard Total International Stock Index Fund 27.0%

Vanguard Total Bond Market II Index Fund 10.2%

At any given time, the Fund's asset allocation may be affected by a variety of factors, such as whether the underlying funds are accepting additional investments.

The Fund's indirect stock holdings consist substantially of large-capitalization U.S. stocks and, to a lesser extent, of mid- and small-cap U.S. stocks, as well as foreign stocks, including emerging markets.

The Fund's indirect bond holdings are a diversified mix of short-, intermediate-, and long-term investment-grade, taxable U.S. government, U.S. agency, and corporate bonds, as well as mortgage-backed securities.

Primary Risks

The Fund is subject to the risks associated with the stock and bond markets, any of which could cause an investor to lose money. An investment in the Fund is not guaranteed. An investor may experience losses, including losses near, at, or after the target year. There is no guarantee that the Fund will provide adequate income at or after the target year. Because stocks usually are more volatile than bonds, and because the Fund currently invests most of its assets in stocks, the Fund's overall level of risk should be higher than that of funds that invest the majority of their assets in bonds; however, the level of risk should be lower than that of funds investing entirely in stocks.

With approximately 90% of its assets currently allocated to stocks, the Fund is proportionately subject to stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices. The Fund is also subject to the following risks associated with investments in foreign stocks: country/regional risk, which is the chance that world events-such as political upheaval, financial troubles, or natural disasters-will adversely affect the value of companies in any one country or region; and currency risk, which is the chance that the value of a foreign investment, measured in U.S. dollars, will decrease because of unfavorable changes in currency exchange rates. Country/regional risk and currency risk are especially high in emerging markets.

With approximately 10% of its assets currently allocated to bonds, the Fund is proportionately subject to bond risks: interest rate risk, which is the chance that bond prices overall will decline because of rising interest rates; income risk, which is the chance that the underlying fund's income will decline because of falling interest rates; credit risk, which is the chance that a bond issuer will fail to pay interest and principal in a timely manner, or that negative perceptions of the issuer's ability to make such payments will cause the price of that bond to decline, thus reducing the underlying fund's return; and call risk, which is the chance that during periods of falling interest rates, issuers of callable bonds may call (redeem) securities with higher coupons or interest rates before their maturity dates. The underlying fund would then lose any price appreciation above the bond's call price and would be forced to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the underlying fund's income. For mortgage-backed securities, this risk is known as prepayment risk.

The Fund is also subject to asset allocation risk, which is the chance that the selection of underlying funds, and the allocation of assets to them, will cause the Fund to underperform other funds with a similar investment objective.

Actual after-tax returns depend on your tax situation and may differ from those shown in the preceding table. When after-tax returns are calculated, it is assumed that the shareholder was in the highest individual federal marginal income tax bracket at the time of each distribution of income or capital gains or upon redemption. State and local income taxes are not reflected in the calculations. Please note that after-tax returns are not relevant for a shareholder who holds fund shares in a tax-deferred account, such as an individual retirement account or a 401(k) plan. Also, figures captioned Return After Taxes on Distributions and Sale of Fund Shares will be higher than other figures for the same period if a capital loss occurs upon redemption and results in an assumed tax deduction for the shareholder.

During the most recent fiscal year, the Fund's portfolio turnover rate was 12%.

Primary Investment Strategies

The Fund invests in other Vanguard mutual funds according to an asset allocation strategy designed for investors planning to retire and leave the work force in or within a few years of 2055 (the target year). The Fund is designed for an investor who plans to withdraw the value of an account in the Fund gradually after the target year. The Fund's asset allocation will become more conservative over time, meaning that the percentage of assets allocated to stocks will decrease while the percentage of assets allocated to bonds and other fixed income investments will increase. Within seven years after 2055, the Fund's asset allocation should become similar to that of the Target Retirement Income Fund. As of September 30, 2011, the Fund's asset allocation among the underlying funds was as follows:

Vanguard Total Stock Market Index Fund 62.6%

Vanguard Total International Stock Index Fund 27.2%

Vanguard Total Bond Market II Index Fund 10.2%

At any given time, the Fund's asset allocation may be affected by a variety of factors, such as whether the underlying funds are accepting additional investments.

The Fund's indirect stock holdings consist substantially of large-capitalization U.S. stocks and, to a lesser extent, of mid- and small-cap U.S. stocks, as well as foreign stocks, including emerging markets.

The Fund's indirect bond holdings are a diversified mix of short-, intermediate-, and long-term investment-grade, taxable U.S. government, U.S. agency, and corporate bonds, as well as mortgage-backed securities.

Primary Risks

The Fund is subject to the risks associated with the stock and bond markets, any of which could cause an investor to lose money. An investment in the Fund is not guaranteed. An investor may experience losses, including losses near, at, or after the target year. There is no guarantee that the Fund will provide adequate income at or after the target year. Because stocks usually are more volatile than bonds, and because the Fund currently invests most of its assets in stocks, the Fund's overall level of risk should be higher than that of funds that invest the majority of their assets in bonds; however, the level of risk should be lower than that of funds investing entirely in stocks.

With approximately 90% of its assets currently allocated to stocks, the Fund is proportionately subject to stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices. The Fund is also subject to the following risks associated with investments in foreign stocks: country/regional risk, which is the chance that world events-such as political upheaval, financial troubles, or natural disasters-will adversely affect the value of companies in a particular country or region; and currency risk, which is the chance that the value of a foreign investment, measured in U.S. dollars, will decrease because of unfavorable changes in currency exchange rates. Country/regional risk and currency risk are especially high in emerging markets.

With approximately 10% of its assets currently allocated to bonds, the Fund is proportionately subject to bond risks: interest rate risk, which is the chance that bond prices overall will decline because of rising interest rates; income risk, which is the chance that the underlying fund's income will decline because of falling interest rates; credit risk, which is the chance that a bond issuer will fail to pay interest and principal in a timely manner, or that negative perceptions of the issuer's ability to make such payments will cause the price of that bond to decline, thus reducing the underlying fund's return; and call risk, which is the chance that during periods of falling interest rates, issuers of callable bonds may call (redeem) securities with higher coupons or interest rates before their maturity dates. The underlying fund would then lose any price appreciation above the bond's call price and would be forced to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the underlying fund's income. For mortgage-backed securities, this risk is known as prepayment risk.

The Fund is also subject to asset allocation risk, which is the chance that the selection of underlying funds, and the allocation of assets to them, will cause the Fund to underperform other funds with a similar investment objective.

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.

Example

The following example is intended to help you compare the cost of investing in the Fund (based on the fees and expenses of the Acquired Funds) with the cost of investing in other mutual funds. It illustrates the hypothetical expenses that you would incur over various periods if you invest $10,000 in the Fund's shares. This example assumes that the Fund provides a return of 5% a year and that operating expenses of the Fund and its underlying funds remain as stated in the preceding table. The results apply whether or not you redeem your investment at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example, No Redemption (Vanguard Target Retirement 2055 Fund Retail) Vanguard Target Retirement 2055 Fund (USD $)	1 YEAR	3 YEAR	5 YEAR	10 YEAR
Vanguard Target Retirement 2055 Fund - Investor Shares	19	61	107	243

Portfolio Turnover

The Fund may pay transaction costs, such as purchase fees, 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 more taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense example, reduce the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 12%.

Portfolio Turnover

The Fund may pay transaction costs, such as purchase fees, 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 more taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense example, reduce the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 14%.

Primary Investment Strategies

The Fund invests in other Vanguard mutual funds according to an asset allocation strategy designed for investors currently in retirement. As of September 30, 2011, the Fund's asset allocation among the underlying funds was as follows:

Vanguard Total Bond Market II Index Fund 45.5%

Vanguard Total Stock Market Index Fund 20.7%

Vanguard Inflation-Protected Securities Fund 20.0%

Vanguard Total International Stock Index Fund 8.8%

Vanguard Prime Money Market Fund 5.0%

At any given time, the Fund's asset allocation may be affected by a variety of factors, such as whether the underlying funds are accepting additional investments.

The Fund's indirect bond holdings are a diversified mix of short-, intermediate-, and long-term investment-grade, taxable U.S. government, U.S. agency, and corporate bonds; inflation-indexed bonds issued by the U.S. government; and mortgage-backed securities.

The Fund's indirect stock holdings consist substantially of large-capitalization U.S. stocks and, to a lesser extent, of mid- and small-cap U.S. stocks, as well as foreign stocks, including emerging markets.

The Fund's indirect short-term investments consist of high-quality, short-term money market instruments.

Primary Risks

The Fund is subject to the risks associated with the stock and bond markets, any of which could cause an investor to lose money. An investment in the Fund is not guaranteed. An investor may experience losses. There is no guarantee that the Fund will provide adequate income through retirement. However, because bonds and short-term investments usually are less volatile than stocks, and because the Fund invests most of its assets in bonds and short-term investments, the Fund's overall level of risk should be low to moderate.

With approximately 70% of its assets allocated to bonds and money market instruments, the Fund is proportionately subject to the following risks: interest rate risk, which is the chance that bond prices overall will decline because of rising interest rates; income risk, which is the chance that an underlying fund's income will decline because of falling interest rates or declining inflation; credit risk, which is the chance that the issuer of a security will fail to pay interest and principal in a timely manner, or that negative perceptions of the issuer's ability to make such payments will cause the price of that security to decline, thus reducing an underlying fund's return; and call risk, which is the chance that during periods of falling interest rates, issuers of callable bonds may call (redeem) securities with higher coupons or interest rates before their maturity dates. An underlying fund would then lose any price appreciation above the bond's call price and would be forced to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the underlying fund's income. For mortgage-backed securities, this risk is known as prepayment risk.

With approximately 30% of its assets allocated to stocks, the Fund is proportionately subject to stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices. The Fund is also subject to the following risks associated with investments in foreign stocks: country/regional risk, which is the chance that world events-such as political upheaval, financial troubles, or natural disasters-will adversely affect the value of companies in any one country or region; and currency risk, which is the chance that the value of a foreign investment, measured in U.S. dollars, will decrease because of unfavorable changes in currency exchange rates. Country/regional risk and currency risk are especially high in emerging markets.

The Fund is also subject to asset allocation risk, which is the chance that the selection of underlying funds, and the allocation of assets to them, will cause the Fund to underperform other funds with a similar investment objective.

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.

Example

The following example is intended to help you compare the cost of investing in the Fund (based on the fees and expenses of the Acquired Funds) with the cost of investing in other mutual funds. It illustrates the hypothetical expenses that you would incur over various periods if you invest $10,000 in the Fund's shares. This example assumes that the Fund provides a return of 5% a year and that operating expenses of the Fund and its underlying funds remain as stated in the preceding table. The results apply whether or not you redeem your investment at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example, No Redemption (Vanguard Target Retirement Income Fund Retail) Vanguard Target Retirement Income Fund (USD $)	1 YEAR	3 YEAR	5 YEAR	10 YEAR
Vanguard Target Retirement Income Fund - Investor Shares	17	55	96	217

Portfolio Turnover

The Fund may pay transaction costs, such as purchase fees, 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 more taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense example, reduce the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 14%.

Primary Investment Strategies

The Fund invests in other Vanguard mutual funds according to an asset allocation strategy designed for investors currently in retirement. As of September 30, 2011, the Fund's asset allocation among the underlying funds was as follows:

Vanguard Total Bond Market II Index Fund 45.5%

Vanguard Total Stock Market Index Fund 20.7%

Vanguard Inflation-Protected Securities Fund 20.0%

Vanguard Total International Stock Index Fund 8.8%

Vanguard Prime Money Market Fund 5.0%

At any given time, the Fund's asset allocation may be affected by a variety of factors, such as whether the underlying funds are accepting additional investments.

The Fund's indirect bond holdings are a diversified mix of short-, intermediate-, and long-term investment-grade, taxable U.S. government, U.S. agency, and corporate bonds; inflation-indexed bonds issued by the U.S. government; and mortgage-backed securities.

The Fund's indirect stock holdings consist substantially of large-capitalization U.S. stocks and, to a lesser extent, of mid- and small-cap U.S. stocks, as well as foreign stocks, including emerging markets.

The Fund's indirect short-term investments consist of high-quality, short-term money market instruments.

Primary Risks

The Fund is subject to the risks associated with the stock and bond markets, any of which could cause an investor to lose money. An investment in the Fund is not guaranteed. An investor may experience losses. There is no guarantee that the Fund will provide adequate income through retirement. However, because bonds and short-term investments usually are less volatile than stocks, and because the Fund invests most of its assets in bonds and short-term investments, the Fund's overall level of risk should be low to moderate.

With approximately 70% of its assets allocated to bonds and money market instruments, the Fund is proportionately subject to the following risks: interest rate risk, which is the chance that bond prices overall will decline because of rising interest rates; income risk, which is the chance that an underlying fund's income will decline because of falling interest rates or declining inflation; credit risk, which is the chance that the issuer of a security will fail to pay interest and principal in a timely manner, or that negative perceptions of the issuer's ability to make such payments will cause the price of that security to decline, thus reducing an underlying fund's return; and call risk, which is the chance that during periods of falling interest rates, issuers of callable bonds may call (redeem) securities with higher coupons or interest rates before their maturity dates. An underlying fund would then lose any price appreciation above the bond's call price and would be forced to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the underlying fund's income. For mortgage-backed securities, this risk is known as prepayment risk.

With approximately 30% of its assets allocated to stocks, the Fund is proportionately subject to stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices. The Fund is also subject to the following risks associated with investments in foreign stocks: country/regional risk, which is the chance that world events-such as political upheaval, financial troubles, or natural disasters-will adversely affect the value of companies in any one country or region; and currency risk, which is the chance that the value of a foreign investment, measured in U.S. dollars, will decrease because of unfavorable changes in currency exchange rates. Country/regional risk and currency risk are especially high in emerging markets.

The Fund is also subject to asset allocation risk, which is the chance that the selection of underlying funds, and the allocation of assets to them, will cause the Fund to underperform other funds with a similar investment objective.

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.

Actual after-tax returns depend on your tax situation and may differ from those shown in the preceding table. When after-tax returns are calculated, it is assumed that the shareholder was in the highest individual federal marginal income tax bracket at the time of each distribution of income or capital gains or upon redemption. State and local income taxes are not reflected in the calculations. Please note that after-tax returns are not relevant for a shareholder who holds fund shares in a tax-deferred account, such as an individual retirement account or a 401(k) plan. Also, figures captioned Return After Taxes on Distributions and Sale of Fund Shares will be higher than other figures for the same period if a capital loss occurs upon redemption and results in an assumed tax deduction for the shareholder.
