Fund Summary

Investment Objective

The Fund seeks to track the performance of a benchmark index that measures the investment return of non-U.S. dollar-denominated investment-grade bonds.

Fees and Expenses

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


Shareholder Fees
(Fees paid directly from your investment)
	Investor Shares	Admiral Shares
Sales Charge (Load) Imposed on Purchases	None	None
Purchase Fee	None	None
Sales Charge (Load) Imposed on Reinvested Dividends	None	None
Redemption Fee	None	None
Account Service Fee (for fund account balances below $10,000)	$20/year	$20/year


Annual Fund Operating Expenses
(Expenses that you pay each year as a percentage of the value of your investment)
	Investor Shares	Admiral Shares
Management Expenses	0.18%	0.15%
12b-1 Distribution Fee	None	None
Other Expenses	0.05%	0.05%
Total Annual Fund Operating Expenses	0.23%	0.20%

Examples

The following examples are intended to help you compare the cost of investing in the Fund’s Investor Shares or Admiral Shares with the cost of investing in other mutual funds. They illustrate the hypothetical expenses that you would incur over various periods if you invest $10,000 in the Fund’s shares. These examples assume that the Shares provide a return of 5% a year and that total annual fund 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:


	1 Year	3 Years
Investor Shares	$24	$74
Admiral Shares	$20	$64

Portfolio Turnover

The Fund has no operating history and therefore has no portfolio turnover information.

Primary Investment Strategies

The Fund employs an indexing investment approach designed to track the performance of the Barclays Global Aggregate ex-USD Float Adjusted RIC Capped Index (USD Hedged). This Index provides a broad-based measure of the global, investment-grade, fixed-rate debt markets. The Index includes government, government agency, corporate, and securitized non-U.S. investment-grade fixed income investments, all issued in currencies other than the U.S. dollar and with maturities of more than one year. The Index is capped, which means that its exposure to any particular bond issuer is limited to a maximum of 20%. Additionally, issuers that individually constitute 5% or more of the Index may not constitute, in the aggregate, more than 48% of the Index. If the Index, as constituted based on market weights, would exceed the 20% or 48% limits, the excess is reallocated to bonds of other issuers represented in the Index. To minimize the currency risk associated with investment in bonds denominated in currencies other than the U.S. dollar, the Fund will attempt to hedge its currency exposures.

The Fund invests by sampling the Index, meaning that it holds a range of securities that, in the aggregate, approximates the full Index in terms of key risk factors and other characteristics. All of the Fund’s investments will be selected through the sampling process, and at least 80% of the Fund’s assets will be invested in bonds included in the Index. The Fund maintains a dollar-weighted average maturity consistent with that of the Index, which generally ranges between 5 and 10 years and, as of March 31, 2013, was 8.2 years.

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 bond market. The Fund is subject to the following risks, which could affect the Fund’s performance:

• Interest rate risk , which is the chance that bond prices overall will decline because of rising interest rates. Interest rate risk should be moderate for the Fund because it invests in a diverse mix of short-, intermediate-, and long-term bonds.

• Income risk , which is the chance that the Fund’s income will decline because of falling interest rates. Income risk is generally moderate for intermediate-term bond funds, so investors should expect the Fund’s monthly income to fluctuate accordingly.

• 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. Credit risk should be low for the Fund because it purchases only bonds that are of investment-grade quality.

• 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 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 Fund’s income. For mortgage-backed securities, this risk is known as prepayment risk . Call/prepayment risk should be low for the Fund because it invests only a small portion of its assets in callable bonds and mortgage-backed securities.

• 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 securities issued by foreign companies, governments, or government agencies. Because the Fund may invest a large portion of its assets in bonds of issuers located in a particular country or region, the Fund’s performance may be hurt disproportionately by the poor performance of its investments in that area. Country/ regional risk for the Fund is high.

• Nondiversification risk , which is the chance that the Fund’s performance may be hurt disproportionately by the poor performance of bonds issued by just a few or even a single issuer. The Fund is considered nondiversified, which means that it may invest a significant percentage of its assets in bonds issued by a small number of issuers. Nondiversification risk for the Fund is high.

hedging transactions. However, it generally is not possible to perfectly hedge the Fund’s foreign currency exposures. The Fund will decline in value if it underhedges a currency that has weakened, or overhedges a currency that has strengthened, relative to the U.S. dollar. In addition, the Fund will incur expenses to hedge its foreign currency exposures. Currency hedging risk for the Fund is low.

• Index sampling risk, which is the chance that the securities selected for the Fund, in the aggregate, will not provide investment performance matching that of the Fund’s target index. Index sampling risk for the Fund should be low.

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.

Investing in Index Funds

What Is Indexing?

Indexing is an investment strategy for tracking the performance of a specified market benchmark, or “index.” An index is an unmanaged group of securities whose overall performance is used as a standard to measure the investment performance of a particular market. There are many types of indexes. Some represent entire markets—such as the U.S. stock market or the U.S. bond market. Other indexes cover market segments—such as small-capitalization stocks or short-term bonds.

An index fund holds all, or a representative sample, of the securities that make up its target index. Index funds attempt to mirror the performance of the target index, for better or worse. However, an index fund generally does not perform exactly like its target index. For example, like all mutual funds, index funds have operating expenses and transaction costs. Market indexes do not, and therefore will usually have a slight performance advantage over funds that track them.

Index funds typically have the following characteristics:

• Variety of investments. Most Vanguard index funds generally invest in the securities of a variety of companies, industries, and government entities.

• Relative performance consistency . Because they seek to track market benchmarks, index funds usually do not perform dramatically better or worse than their benchmarks.

• Low cost . Index funds are inexpensive to run compared with actively managed funds.

They have low or no research costs and typically keep trading activity—and thus dealer markups and other transaction costs—to a minimum.

More on the Fund

This prospectus describes the primary risks you would face as a Fund shareholder. It is important to keep in mind one of the main axioms of investing: Generally, the higher the risk of losing money, the higher the potential reward. The reverse, also, is generally true: The lower the risk, the lower the potential reward. As you consider an investment in any mutual fund, you should take into account your personal tolerance for fluctuations in the securities markets. Look for this symbol throughout the prospectus. It is used to mark detailed information about the more significant risks that you would confront as a Fund shareholder. To highlight terms and concepts important to mutual fund investors, we have provided Plain Talk ^® explanations along the way. Reading the prospectus will help you decide whether the Fund is the right investment for you. We suggest that you keep this prospectus for future reference.

Share Class Overview

This prospectus offers the Fund‘s Investor Shares and Admiral Shares. A separate prospectus offers the Fund‘s Institutional Shares, which are generally for investors who invest a minimum of $5 million. In addition, the Fund issues an exchange-traded class of shares (ETF Shares) and a Transition Share class, each of which is offered through a separate prospectus. The Transition Share class will only be available to other Vanguard funds.

All share classes offered by the Fund have the same investment objective, strategies, and policies. However, different share classes have different expenses ; as a result, their investment performances will differ.

Plain Talk About Fund Expenses

All mutual funds have operating expenses. These expenses, which are deducted

from a fund’s gross income, are expressed as a percentage of the net assets of

the fund. Assuming that operating expenses remain as stated in the Fees and

Expenses section, Vanguard Total International Bond Index Fund’s expense

ratios would be as follows: for Investor Shares, 0.23%, or $2.30 per $1,000 of

average net assets; for Admiral Shares, 0.20%, or $2.00 per $1,000 of average

net assets.

Plain Talk About Costs of Investing

Costs are an important consideration in choosing a mutual fund. That’s because

you, as a shareholder, pay a proportionate share of the costs of operating a fund,

plus any transaction costs incurred when the fund buys or sells securities. These

costs can erode a substantial portion of the gross income or the capital

appreciation a fund achieves. Even seemingly small differences in expenses can,

over time, have a dramatic effect on a fund’s performance.

The following sections explain the primary investment strategies and policies that the Fund uses in pursuit of its objective. The Fund’s board of trustees, which oversees the Fund’s management, may change investment strategies or policies in the interest of shareholders without a shareholder vote, unless those strategies or policies are designated as fundamental. The Fund‘s policy of investing at least 80% of its assets in securities that are included in its target index may be changed only upon 60 days‘ notice to shareholders. Note that the Fund‘s investment objective is not fundamental and may be changed without a shareholder vote.

Market Exposure

The Fund is subject to interest rate risk, which is the chance that bond prices overall will decline because of rising interest rates. Interest rate risk should be moderate for the Fund because it invests in a diverse mix of short-, intermediate-, and long-term bonds.

Although bonds are often thought to be less risky than stocks, there have been periods when bond prices have fallen significantly because of rising interest rates. For instance, prices of U.S. long-term bonds fell by almost 48% between December 1976 and September 1981. Note that over comparable periods of time, the prices of foreign bonds and U.S. bonds may increase or decrease by different amounts, and in some cases may move in opposite directions.

To illustrate the relationship between bond prices and interest rates, the following table shows the effect of a 1% and a 2% change (both up and down) in interest rates on the values of three noncallable bonds of different maturities, each with a face value of $1,000.


How Interest Rate Changes Affect the Value of a $1,000 Bond ¹
	After a 1%	After a 1%	After a 2%	After a 2%
Type of Bond (Maturity)	Increase	Decrease	Increase	Decrease
Short-Term (2.5 years)	$977	$1,024	$954	$1,049
Intermediate-Term (10 years)	922	1,086	851	1,180
Long-Term (20 years)	874	1,150	769	1,328
1 Assuming a 4% coupon.

These figures are for illustration only; you should not regard them as an indication of future performance of foreign bonds generally or the Fund in particular.

Plain Talk About Bonds and Interest Rates

As a rule, when interest rates rise, bond prices fall. The opposite is also true:

Bond prices go up when interest rates fall. Why do bond prices and interest rates

move in opposite directions? Let’s assume that you hold a bond offering a 4%

yield. A year later, interest rates are on the rise and bonds of comparable quality

and maturity are offered with a 5% yield. With higher-yielding bonds available,

you would have trouble selling your 4% bond for the price you paid—you would

probably have to lower your asking price. On the other hand, if interest rates were

falling and 3% bonds were being offered, you should be able to sell your 4%

bond for more than you paid.

How mortgage-backed securities are different: In general, declining interest rates

will not lift the prices of mortgage-backed securities—such as GNMAs—as much

as the prices of comparable bonds. Why? Because when interest rates fall, the

bond market tends to discount the prices of mortgage-backed securities for

prepayment risk—the possibility that homeowners will refinance their mortgages

at lower rates and cause the bonds to be paid off prior to maturity. In part to

compensate for this prepayment possibility, mortgage-backed securities tend to

offer higher yields than other bonds of comparable credit quality and maturity.

Changes in interest rates can affect bond income as well as bond prices .

The Fund is subject to income risk, which is the chance that the Fund’s income will decline because of falling interest rates. A fund’s income declines when interest rates fall because the fund then must invest new cash flow and cash from maturing bonds in lower-yielding bonds. Income risk is generally moderate for the Fund because it invests in a diverse mix of short-, intermediate-, and long-term bonds.

Plain Talk About Bond Maturities

A bond is issued with a specific maturity date—the date when the issuer must pay

back the bond’s principal (face value). Bond maturities range from less than 1 year

to more than 30 years. Typically, the longer a bond’s maturity, the more price risk

you, as a bond investor, face as interest rates rise—but also the higher yield you

could receive. Longer-term bonds are more suitable for investors willing to take a

greater risk of price fluctuations to get higher and more stable interest income.

Shorter-term bond investors should be willing to accept lower yields and greater

income variability in return for less fluctuation in the value of their investment.

Although falling interest rates tend to strengthen bond prices, they can cause other sorts of problems for bond fund investors—bond calls and prepayments.

The Fund is subject to 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 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 Fund’s income. For mortgage-backed securities, this risk is known as prepayment risk.

Because the Fund invests only a small portion of its assets in callable bonds and mortgage-backed securities, call/prepayment risk should be low for the Fund.

The Fund is subject to 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. Credit risk should be low for the Fund because it purchases only bonds that are of investment-grade quality.

Although the Fund purchases only investment-grade bonds, a bond held by the Fund may be downgraded, causing the Fund to hold securities below investment-grade. If a bond is downgraded below investment-grade, the Fund will generally attempt to sell the bond within a reasonable period of time. If the Fund determines that the bond cannot be sold at a reasonable price, the Fund may hold the bond until a reasonable price for the bond may be obtained.

Plain Talk About Credit Quality

A bond’s credit-quality rating is an assessment of the issuer’s ability to pay interest

on the bond and, ultimately, to repay the principal. Credit quality is evaluated by one

of the nationally recognized statistical rating organizations (for example, Moody‘s or

Standard & Poor‘s) or through independent analysis conducted by a fund’s advisor.

The lower the rating, the greater the chance—in the rating agency’s or advisor’s

opinion—that the bond issuer will default, or fail to meet its payment obligations.

All things being equal, the lower a bond’s credit rating, the higher its yield should be

to compensate investors for assuming additional risk. Investment-grade bonds are

those rated in one of the four highest ratings categories. A fund may treat an

unrated bond as investment-grade if warranted by the advisor’s analysis.

The Fund is subject to 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 bonds issued by foreign companies, governments, or government agencies. Because the Fund may invest a large portion of its assets in bonds of issuers located in a particular country or region, the Fund’s performance may be hurt disproportionately by the poor performance of its investments in that area. Country/regional risk for the Fund is high.

As of March 31, 2013, the target index for the Fund held a substantial percentage of its assets in bonds of issuers located in just a handful of countries, as shown in the following table:


Barclays Global Aggregate ex-USD
Float Adjusted RIC Capped Index (USD Hedged)
Japan	22.5%
France	11.6
Germany	11.0
United Kingdom	7.9
Italy	7.9
Canada	5.8
Spain	5.5
Total	72.2%

The Fund is subject to nondiversification risk, which is the chance that the Fund’s performance may be hurt disproportionately by the poor performance of bonds issued by just a few or even a single issuer. The Fund is considered nondiversified, which means that it may invest a significant percentage of its assets in bonds issued by a small number of issuers. Nondiversification risk for the Fund is high.

As of March 31, 2013, the target index for the Fund held a substantial percentage of its assets in bonds of a small number of issuers, as shown in the following table:


Barclays Global Aggregate ex-USD
Float Adjusted RIC Capped Index (USD Hedged)
Government of Japan	19.0%
Government of Italy	6.4
Government of France	5.7
Government of United Kingdom	4.6
Government of Germany	4.5
Total	40.2%

The Fund is subject to currency hedging risk, which is the chance that the currency hedging transactions entered into by the Fund may not perfectly offset the Fund's foreign currency exposures. The Fund seeks to mimic the performance of foreign bonds without regard to currency exchange rate fluctuations. To accomplish this goal, the Fund attempts to offset, or hedge, its foreign currency exposures by entering into currency hedging transactions. However, it generally is not possible to perfectly hedge the Fund’s foreign currency exposures.The Fund will decline in value if it underhedges a currency that has weakened, or overhedges a currency that has strengthened, relative to the U.S. dollar. In addition, the Fund will incur expenses to hedge its foreign currency exposures. By entering into currency hedging transactions, the Fund may eliminate any chance to benefit from favorable fluctuations in relevant currency exchange rates. Currency hedging risk for the Fund is low.

The following summary table is provided to help you identify the level of the Fund’s various risk.

Plain Talk About International Investing

U.S. investors who invest abroad will encounter risks not typically associated

with U.S. companies because foreign stock and bond markets operate differently

from the U.S. markets. For instance, foreign governments and companies are not

subject to the same accounting, auditing, and financial-reporting standards and

practices as the U.S. government and U.S. companies, and their bonds may not

be as liquid as those of similar U.S. entities. In addition, foreign bond markets and

dealers may be subject to less government supervision and regulation than their

counterparts in the United States. These factors, among others, could negatively

affect the returns U.S. investors receive from foreign investments.

Security Selection

Types of bonds. The Fund tracks the Barclays Global Aggregate ex-USD Float Adjusted RIC Capped Index (USD Hedged). This Index provides a broad-based measure of the global, investment-grade, fixed-rate debt markets. The Index includes government, government agency, corporate, and securitized non-U.S. investment-grade fixed income investments, all issued in currencies other than the U.S. dollar and with maturities of more than one year. The Index is capped, which means that its exposure to any particular bond issuer, including foreign governments, is limited to a maximum of 20%. Additionally, issuers that individually constitute 5% or more of the Index may not constitute, in the aggregate, more than 48% of the Index. If the Index, as constituted based on market weights, would exceed the 20% or 48% limits, the excess is reallocated to bonds of other issuers represented in the Index. To minimize the currency risk associated with investment in bonds denominated in currencies other than the U.S. dollar, the Fund will attempt to hedge its currency exposures.

Local currency bonds are bonds denominated in the local currency of a non-U.S. country. They can be issued by foreign governments, government agencies, and corporations. To the extent that a Fund owns local currency bonds and hedges its currency exposure, it is subject to currency hedging risk. For a hedged portfolio,

currency hedging risk should be low. All of the bonds held by the Fund will be local currency bonds.

The number of bonds in the Fund’s target index, as of March 31, 2013, was 7,377.

Index sampling strategy. Because it would be very expensive and inefficient to buy and sell all, or substantially all, of the bonds held in its target index—which is an indexing strategy called “replication”—the Fund uses index “sampling” techniques to select securities. Using sophisticated computer programs, the Fund’s advisor generally selects a representative sample of securities that approximates the full target index in terms of key risk factors and other characteristics. These factors include country of origin, duration, cash flow, credit quality, and callability of the underlying bonds. Because the Fund does not hold all of the securities in its target index, some of the securities (and issuers) that are held will likely be overweighted (or underweighted) compared with the target index.

The Fund is subject to index sampling risk, which is the chance that the securities selected for the Fund, in the aggregate, will not provide investment performance matching that of the Fund’s target index. Index sampling risk for the Fund should be low.

Other Investment Policies and Risks

The Fund will invest at least 80% of its assets in bonds held in its target index. Subject to a 20% limit, the Fund may purchase investments that are not included in its target index or may hold bonds that, when acquired, were included in the index but subsequently were removed.

The Fund reserves the right to substitute a different index for the index it currently tracks if the current index is discontinued, if the Fund’s agreement with the sponsor of its target index is terminated, or for any other reason determined in good faith by the Fund’s board of trustees. In any such instance, the substitute index would measure the same general market segment as the current index.

The Fund may invest in derivatives. In general, derivatives may involve risks different from, and possibly greater than, those of the underlying securities, assets, or market indexes.

Generally speaking, a derivative is a financial contract whose value is based on the value of a financial asset (such as a stock, bond, or currency), a physical asset (such as gold, oil, or wheat), or a market index (such as the Barclays U.S. Aggregate Bond Index). The Fund may invest in derivatives only if the expected risks and rewards of the derivatives are consistent with the investment objective, policies, strategies, and risks of the Fund as disclosed in this prospectus. In particular, derivatives will be used only when they may help the advisor:

• Invest in eligible asset classes with greater efficiency and lower cost than is possible through direct investment;

• Add value when these instruments are attractively priced;

• Adjust sensitivity to changes in interest rates; or

• Hedge foreign currency exposures.

The Fund‘s derivative investments may include fixed income futures contracts, foreign currency exchange forwards, fixed income options, interest rate swaps, total return swaps, credit default swaps, or other derivatives. Losses (or gains) involving futures contracts can sometimes be substantial—in part because a relatively small price movement in a futures contract may result in an immediate and substantial loss (or gain) for a fund. Similar risks exist for other types of derivatives.

The Fund may enter into foreign currency exchange forward contracts, which are a type of derivative, in order to hedge its foreign currency exposures. A foreign currency exchange forward contract is an agreement to buy or sell a country’s currency at a specific price on a specific date, usually 30, 60, or 90 days in the future. These contracts will be used in an effort to offset any changes in the dollar value of foreign bonds attributable to changes in the value of the bonds’ local currencies relative to the U.S. dollar. Although such contracts can protect the Fund from unfavorable fluctuations in currency exchange rates, they also reduce or eliminate any chance for the Fund to benefit from favorable exchange rate fluctuations. Notably, foreign currency exchange forward contracts do not prevent the Fund’s securities from falling in value for reasons unrelated to currency exchange rates, such as interest rate increases, credit downgrades, etc.

The Fund is subject to counterparty risk with respect to its currency hedging transactions. Counterparty risk is the chance that the counterparty to a currency forward contract with the Fund is unable or unwilling to meet its financial obligations. Counterparty risk is low for the Fund.

Plain Talk About Derivatives

Derivatives can take many forms. Some forms of derivatives, such as

exchange-traded futures and options on securities, commodities, or indexes,

have been trading on regulated exchanges for decades. These types of

derivatives are standardized contracts that can easily be bought and sold, and

whose market values are determined and published daily. Nonstandardized

derivatives (such as swap agreements and foreign currency exchange forward

contracts), on the other hand, tend to be more specialized or complex, and may

be harder to value.

Vanguard may invest a small portion of the Fund’s assets in shares of bond exchange-traded funds (ETFs). ETFs typically provide returns similar to those of the bonds listed in the index or in a subset of the index. Vanguard may purchase ETFs when doing so will reduce the Fund’s transaction costs or add value because the instruments are favorably priced. Vanguard receives no additional revenue from Fund assets invested in ETF Shares of other Vanguard funds. Fund assets invested in ETF Shares are excluded when allocating to the Fund its share of the costs of Vanguard operations.

Cash Management

The Fund’s daily cash balance may be invested in one or more Vanguard CMT Funds, which are very low-cost money market funds. When investing in a Vanguard CMT Fund, the Fund bears its proportionate share of the at-cost expenses of the CMT Fund in which it invests.

Temporary Investment Measures

The Fund may temporarily depart from its normal investment policies and strategies when the advisor believes that doing so is in the Fund’s best interest, so long as the alternative is consistent with the Fund’s investment objective. For instance, the Fund may invest beyond its normal limits in derivatives or exchange-traded funds that are consistent with the Fund’s objective when those instruments are more favorably priced or provide needed liquidity, as might be the case when the Fund receives large cash flows that it cannot prudently invest immediately.

Frequent Trading or Market-Timing

holding investments such as small-cap stocks and high-yield bonds. As money is shifted into and out of a fund by a shareholder engaging in frequent trading, the fund incurs costs for buying and selling securities, resulting in increased brokerage and administrative costs. These costs are borne by all fund shareholders, including the long-term investors who do not generate the costs. In addition, frequent trading may interfere with an advisor’s ability to efficiently manage the fund.

Policies to Address Frequent Trading. The Vanguard funds (other than money market funds and short-term bond funds) do not knowingly accommodate frequent trading. The board of trustees of each Vanguard fund (other than money market funds and short-term bond funds) has adopted policies and procedures reasonably designed to detect and discourage frequent trading and, in some cases, to compensate the fund for the costs associated with it. These policies and procedures do not apply to Vanguard ETF ^® Shares because frequent trading in ETF Shares does not disrupt portfolio management or otherwise harm fund shareholders. Although there is no assurance that Vanguard will be able to detect or prevent frequent trading or market-timing in all circumstances, the following policies have been adopted to address these issues:

• Each Vanguard fund reserves the right to reject any purchase request—including exchanges from other Vanguard funds—without notice and regardless of size. For example, a purchase request could be rejected because of a history of frequent trading by the investor or if Vanguard determines that such purchase may negatively affect a fund’s operation or performance.

• Each Vanguard fund (other than money market funds and short-term bond funds) generally prohibits, except as otherwise noted in the Investing With Vanguard section, an investor’s purchases or exchanges into a fund account for 60 calendar days after the investor has redeemed or exchanged out of that fund account.

• Certain Vanguard funds charge shareholders purchase and/or redemption fees on transactions.

See the Investing With Vanguard section of this prospectus for further details on Vanguard’s transaction policies.

Each fund (other than money market funds), in determining its net asset value, will, when appropriate, use fair-value pricing, as described in the Share Price section. Fair-value pricing may reduce or eliminate the profitability of certain frequent-trading strategies.

Do not invest with Vanguard if you are a market-timer.

Turnover Rate

Although the Fund generally seeks to invest for the long term, the Fund may sell securities regardless of how long they have been held. Generally, an index fund sells securities in response to cash redemption requests, to changes in the composition of a target index, or to manage the fund’s duration.

Plain Talk About Turnover Rate

Turnover rate gives an indication of how transaction costs, which are not included

in the fund’s expense ratio, could affect the fund’s future returns. In general, the

greater the volume of buying and selling by the fund, the greater the impact that

dealer markups and other transaction costs will have on its return. Also, funds

with high turnover rates may be more likely to generate capital gains that must be

distributed to shareholders as taxable income.

The Fund and Vanguard

The Fund is a member of The Vanguard Group, a family of more than 180 mutual funds holding assets of approximately $2.1 trillion. All of the funds that are members of The Vanguard Group (other than funds of funds) share in the expenses associated with administrative services and business operations, such as personnel, office space, and equipment.

Vanguard Marketing Corporation provides marketing services to the funds. Although shareholders do not pay sales commissions or 12b-1 distribution fees, each fund (other than a fund of funds) or each share class of a fund (in the case of a fund with multiple share classes) pays its allocated share of the Vanguard funds’ marketing costs.

Plain Talk About Vanguard’s Unique Corporate Structure

The Vanguard Group is truly a mutual mutual fund company. It is owned jointly by

the funds it oversees and thus indirectly by the shareholders in those funds.

Most other mutual funds are operated by management companies that may be

owned by one person, by a private group of individuals, or by public investors

who own the management company’s stock. The management fees charged by

these companies include a profit component over and above the companies’ cost

of providing services. By contrast, Vanguard provides services to its member

funds on an at-cost basis, with no profit component, which helps to keep the

funds’ expenses low.

Investment Advisor

The Vanguard Group, Inc. (Vanguard), P.O. Box 2600, Valley Forge, PA 19482, which began operations in 1975, serves as advisor to the Fund through its Fixed Income Group. As of March 31, 2013, Vanguard served as advisor for approximately $1.8 trillion in assets. Vanguard provides investment advisory services to the Fund on an at-cost basis, subject to the supervision and oversight of the trustees and officers of the Fund.

For a discussion of why the board of trustees approved the Fund’s investment advisory arrangement, see the annual report to shareholders covering the fiscal year ended October 31, 2013, which will be available 60 days after that date.

Vanguard’s Fixed Income Group is overseen by:

Mortimer J. Buckley , Chief Investment Officer and Managing Director of Vanguard. As Chief Investment Officer, he is responsible for the oversight of Vanguard’s Equity Investment and Fixed Income Groups. The investments managed by these two groups include active quantitative equity funds, equity index funds, active bond funds, index bond funds, stable value portfolios, and money market funds. Mr. Buckley joined Vanguard in 1991 and has held various senior leadership positions with Vanguard. He received his A.B. in economics from Harvard and an M.B.A. from Harvard Business School.

Robert F. Auwaerter , Principal of Vanguard and head of Vanguard’s Fixed Income Group. He has direct oversight responsibility for all money market funds, bond funds, and stable value portfolios managed by the Fixed Income Group. He has managed investment portfolios since 1978 and has been with Vanguard since 1981. He received his B.S. in finance from The Wharton School of the University of Pennsylvania and an M.B.A. from Northwestern University.

Kenneth E. Volpert , CFA, Principal of Vanguard and head of Vanguard’s Taxable Bond Group. He has direct oversight responsibility for all taxable bond funds managed by the Fixed Income Group. He has managed investment portfolios since 1982 and has been with Vanguard since 1992. He received his B.S. from the University of Illinois and an M.B.A. from the University of Chicago.

The managers primarily responsible for the day-to-day management of the Fund are:

Joshua C. Barrickman , CFA, Principal of Vanguard and head of Vanguard’s Bond Index Group. He has been with Vanguard since 1998; has worked in investment management since 1999; has managed investment portfolios since 2005; and has co-managed the Fund since its inception in May 2013. Education: B.S., Ohio Northern University; M.B.A., Lehigh University.

Yan Pu , CFA, Portfolio Manager. She has worked in investment management for Vanguard since 2004; has managed investment portfolios since 2007; and has co-managed the Fund since its inception in May 2013. Education: B.S., JiNan University; M.B.A., Drexel University.

Dividends, Capital Gains, and Taxes

Fund Distributions

The Fund distributes to shareholders virtually all of its net income (interest less expenses) as well as any net capital gains realized from the sale of its holdings. The Fund’s income dividends are declared monthly and distributed monthly; capital gains distributions, if any, generally occur annually in December. You can receive distributions of income or capital gains in cash, or you can have them automatically reinvested in more shares of the Fund.

Plain Talk About Distributions

As a shareholder, you are entitled to your portion of a fund’s income from interest

as well as capital gains from the fund’s sale of investments. Income consists of

interest the fund earns from its money market and bond investments. Capital

gains are realized whenever the fund sells securities for higher prices than it paid

for them. These capital gains are either short-term or long-term, depending on

whether the fund held the securities for one year or less or for more than one year.

Basic Tax Points

Vanguard will send you a statement each year showing the tax status of all your distributions. In addition, investors in taxable accounts should be aware of the following basic federal income tax points:

• Distributions are taxable to you whether or not you reinvest these amounts in additional Fund shares.

• Distributions declared in December—if paid to you by the end of January—are taxable as if received in December.

• Any dividend or short-term capital gains distributions that you receive are taxable to you as ordinary income.

• Any distributions of net long-term capital gains are taxable to you as long-term capital gains, no matter how long you’ve owned shares in the Fund.

• Capital gains distributions may vary considerably from year to year as a result of the Fund‘s normal investment activities and cash flows.

• A sale or exchange of Fund shares is a taxable event. This means that you may have a capital gain to report as income, or a capital loss to report as a deduction, when you complete your tax return.

• Any conversion between classes of shares of the same fund is a nontaxable event. By contrast, an exchange between classes of shares of different funds is a taxable event.

Individuals, trusts, and estates whose income exceeds certain threshold amounts will be subject to a 3.8% Medicare contribution tax on “net investment income” in tax years beginning on or after January 1, 2013. Net investment income includes dividends paid by the Fund and capital gains from any sale or exchange of Fund shares.

Dividend and capital gains distributions that you receive, as well as your gains or losses from any sale or exchange of Fund shares, may be subject to state and local income taxes.

The Funds may be subject to foreign taxes or foreign tax withholding on dividends, interest, and some capital gains that the Fund receives on foreign securities. You may qualify for an offsetting credit or deduction under U.S. tax laws for any amount designated as your portion of a Fund’s foreign tax obligations, provided that you meet certain requirements. See your tax advisor or IRS publications for more information.

This prospectus provides general tax information only. If you are investing through a tax-deferred retirement account, such as an IRA, special tax rules apply. Please consult your tax advisor for detailed information about any tax consequences for you.

General Information

Backup withholding. By law, Vanguard must withhold 28% of any taxable distributions or redemptions from your account if you do not:

Provide us with your correct taxpayer identification number;
Certify that the taxpayer identification number is correct; and
Confirm that you are not subject to backup withholding.

Similarly, Vanguard must withhold taxes from your account if the IRS instructs us to do so.

Foreign investors. Vanguard funds offered for sale in the United States (Vanguard U.S. funds), including the Fund offered in this prospectus, generally are not sold outside the United States, except to certain qualified investors. Non-U.S. investors should be aware that U.S. withholding and estate taxes and certain U.S. tax reporting requirements may apply to any investments in Vanguard U.S. funds. Foreign investors should visit the “Non-U.S. Investors” page on our website at vanguard.com for information on Vanguard’s non-U.S. products.

Invalid addresses. If a dividend or capital gains distribution check mailed to your address of record is returned as undeliverable, Vanguard will automatically reinvest the distribution and all future distributions until you provide us with a valid mailing address. Reinvestments will receive the net asset value calculated on the date of the reinvestment.

Share Price

Share price, also known as net asset value (NAV), is calculated each business day as of the close of regular trading on the New York Stock Exchange, generally 4 p.m., Eastern time. Each share class has its own NAV, which is computed by dividing the total assets, minus liabilities, allocated to each share class by the number of Fund shares outstanding for that class. On holidays or other days when the Exchange is closed, the NAV is not calculated, and the Fund does not transact purchase or redemption requests. However, on those days the value of the Fund’s assets may be affected to the extent that the Fund holds foreign securities that trade on foreign markets that are open.

Debt securities held by a Vanguard fund are valued based on information furnished by an independent pricing service or market quotations. Certain short-term debt instruments used to manage a fund’s cash are valued on the basis of amortized cost. The values of any mutual fund shares held by a fund are based on the NAVs of the shares. The values of any ETF or closed-end fund shares held by a fund are based on the market value of the shares.

When a fund determines that pricing-service information or market quotations either are not readily available or do not accurately reflect the value of a security, the security is priced at its fair value (the amount that the owner might reasonably expect to receive upon the current sale of the security). Additionally, a fund will use fair-value pricing if the value of a security it holds has been materially affected by events occurring before the fund’s pricing time but after the close of the primary markets or exchanges on which the security is traded. This most commonly occurs with foreign securities, which may trade on foreign exchanges or markets that close many hours before the fund’s pricing time. Intervening events might be: company-specific (e.g., earnings report, material credit events), or country-specific or regional/global (e.g., natural

disaster, economic or political news, act of terrorism, interest rate change). Intervening events include price movements in U.S. markets that are deemed to affect the value of foreign securities. A fund may also use fair-value pricing on bond market holidays when the fund is open for business (such as Columbus Day and Veteran’s Day).

Fair-value prices are determined by Vanguard according to procedures adopted by the board of trustees. When fair-value pricing is employed, the prices of securities used by a fund to calculate the NAV may differ from quoted or published prices for the same securities.

Vanguard fund share prices are published daily on our website at vanguard.com/prices.

Investing With Vanguard

This section of the prospectus explains the basics of doing business with Vanguard. Vanguard fund shares can be held directly with Vanguard or indirectly through an intermediary, such as a bank, a broker, or an investment advisor. If you hold Vanguard fund shares directly with Vanguard, you should carefully read each topic within this section that pertains to your relationship with Vanguard. If you hold Vanguard fund shares indirectly through an intermediary (including shares held through a Vanguard brokerage account), please see Investing With Vanguard Through Other Firms , and also refer to your account agreement with the intermediary for information about transacting in that account. Vanguard reserves the right to change the following policies without notice. Please call or check online for current information. See

Contacting Vanguard.

For Vanguard fund shares held directly with Vanguard, each fund you hold in an account is a separate “fund account.” For example, if you hold three funds in a nonretirement account titled in your own name, two funds in a nonretirement account titled jointly with your spouse, and one fund in an individual retirement account, you have six fund accounts—and this is true even if you hold the same fund in multiple accounts. Note that each reference to “you” in this prospectus applies to any one or more registered account owners or persons authorized to transact on your account.

Purchasing Shares

Vanguard reserves the right, without notice, to increase or decrease the minimum amount required to open, convert shares to, or maintain a fund account, or to add to an existing fund account.

Investment minimums may differ for certain categories of investors.

Account Minimums for Investor Shares To open and maintain an account. $3,000.

Add to an existing account. Generally $100 (other than by Automatic Investment Plan, which has no established minimum).

Account Minimums for Admiral Shares

To open and maintain an account. $10,000. If you request Admiral Shares when you open a new account, but the investment amount does not meet the account minimum for Admiral Shares, your investment will be placed in Investor Shares of the Fund. Institutional clients should contact Vanguard for information on special eligibility rules that may apply to them.

Add to an existing account. Generally $100 (other than by Automatic Investment Plan, which has no established minimum).

How to Initiate a Purchase Request

Be sure to check Exchanging Shares, Frequent-Trading Limitations, and Other Rules You Should Know before placing your purchase request.

Online. You may open certain types of accounts, request a purchase of shares, and request an exchange through our website or our mobile application if you are registered for online access.

By telephone. You may call Vanguard to begin the account registration process or request that the account-opening forms be sent to you. You may also call Vanguard to request a purchase of shares in your account or to request an exchange. See

Contacting Vanguard .

By mail. You may send Vanguard your account registration form and check to open a new fund account. To add to an existing fund account, you may send your check with an Invest-by-Mail form (from a transaction confirmation or your account statement), with a deposit slip (available online), or with a written request. You may also send a written request to Vanguard to make an exchange. For a list of Vanguard addresses, see Contacting Vanguard .

How to Pay for a Purchase

By electronic bank transfer. You may purchase shares of a Vanguard fund through an electronic transfer of money from a bank account. To establish the electronic bank transfer option on an account, you must designate the bank account online, complete a special form, or fill out the appropriate section of your account registration form. After the option is set up on your account, you can purchase shares by electronic bank transfer on a regular schedule (Automatic Investment Plan) or from time to time. Your purchase request can be initiated online (if you are registered for online access), by telephone, or by mail.

By wire. Wiring instructions vary for different types of purchases. Please call Vanguard for instructions and policies on purchasing shares by wire. See Contacting Vanguard.

By check. You may make initial or additional purchases to your fund account by sending a check or through our mobile application if you are registered for online access. Also see How to Initiate a Purchase Request. Make your check payable to Vanguard and include the appropriate fund number (e.g., Vanguard—xx). For a list of Fund numbers (for share classes in this prospectus), see Additional Information .

By exchange. You may purchase shares of a Vanguard fund using the proceeds from the simultaneous redemption of shares of another Vanguard fund. You may initiate an exchange online (if you are registered for online access), by telephone, or by written request. See Exchanging Shares .

Trade Date

The trade date for any purchase request received in good order will depend on the day and time Vanguard receives your request, the manner in which you are paying, and the type of fund you are purchasing. Your purchase will be executed using the NAV as calculated on the trade date. NAVs are calculated only on days that the New York Stock Exchange (NYSE) is open for trading (a business day).

For purchases by check into all funds other than money market funds, and for purchases by exchange , wire , or electronic bank transfer (not using an Automatic Investment Plan) into all funds: If the purchase request is received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the trade date for the purchase will be the same day. If the purchase request is received on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date for the purchase will be the next business day.

For purchases by check into money market funds: If the purchase request is received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the trade date for the purchase will be the next business day. If the purchase request is received on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date for the purchase will be the second business day following the day Vanguard receives the purchase request. Because money market instruments must be purchased with federal funds and it takes a money market mutual fund one business day to convert check proceeds into federal funds, the trade date for the purchase will be one business day later than for other funds.

For purchases by electronic bank transfer using an Automatic Investment Plan : Your trade date generally will be one business day before the date you designated for withdrawal from your bank account.

If your purchase request is not accurate and complete, it may be rejected. See Other Rules You Should Know—Good Order .

For further information about purchase transactions, consult our website at vanguard.com or see Contacting Vanguard .

Other Purchase Rules You Should Know

Admiral Shares. Please note that Admiral Shares generally are not available for:

SIMPLE IRAs and Individual 403(b)(7) Custodial Accounts or
Certain retirement plan accounts receiving special administrative services from

Vanguard, including Vanguard Individual 401(k) Plans.

Check purchases. All purchase checks must be written in U.S. dollars and must be drawn on a U.S. bank. Vanguard does not accept cash, traveler’s checks, or money orders. In addition, Vanguard may refuse “starter checks” and checks that are not made payable to Vanguard.

New accounts. We are required by law to obtain from you certain personal information that we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your identity, Vanguard reserves the right, without notice, to close your account or take such other steps as we deem reasonable.

Refused or rejected purchase requests. Vanguard reserves the right to stop selling fund shares or to reject any purchase request at any time and without notice, including, but not limited to, purchases requested by exchange from another Vanguard fund. This also includes the right to reject any purchase request because of a history of frequent trading by the investor or because the purchase may negatively affect a fund’s operation or performance.

Large purchases. Please call Vanguard before attempting to invest a large dollar amount.

No cancellations. Vanguard will not accept your request to cancel any purchase request once processing has begun. Please be careful when placing a purchase request.

Converting Shares

When a conversion occurs, you receive shares of one class in place of shares of another class of the same fund. At the time of conversion, the dollar value of the “new” shares you receive equals the dollar value of the “old” shares that were converted. In other words, the conversion has no effect on the value of your investment in the fund at the time of the conversion. However, the number of shares you own after the conversion may be greater than or less than the number of shares you owned before the conversion, depending on the net asset values of the two share classes.

A conversion between share classes of the same fund is a nontaxable event.

Trade Date

The trade date for any conversion request received in good order will depend on the day and time Vanguard receives your request. Your conversion will be executed using the NAVs of the different share classes on the trade date. NAVs are calculated only on days that the NYSE is open for trading (a business day).

For a conversion request (other than a request to convert to ETF Shares) received by Vanguard on a business day before the close of regular trading on the NYSE (generally

4 p.m., Eastern time), the trade date will be the same day. For a conversion request received on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date will be the next business day. See Other Rules You Should Know.

Conversions From Investor Shares to Admiral Shares

Self-directed conversions. If your account balance in the Fund is at least $10,000, you may ask Vanguard to convert your Investor Shares to Admiral Shares. You may request a conversion through our website (if you are registered for online access), by telephone, or by mail. Institutional clients should contact Vanguard for information on special eligibility rules that may apply to them. See Contacting Vanguard .

Automatic conversions. Vanguard conducts periodic reviews of account balances and may, if your account balance in the Fund exceeds $10,000, automatically convert your Investor Shares to Admiral Shares. You will be notified before an automatic conversion occurs and will have an opportunity to instruct Vanguard not to effect the conversion. Institutional clients should contact Vanguard for information on special eligibility rules that may apply to them.

Conversions to Institutional Shares

You are eligible for a self-directed conversion from another share class to Institutional Shares of the same Fund, provided that your account meets all Institutional Shares’ eligibility requirements. You may request a conversion through our website (if you are registered for online access), or you may contact Vanguard by telephone or by mail to request this transaction. Accounts that qualify for Institutional Shares will not be automatically converted.

Conversions to ETF Shares

Owners of conventional shares (i.e., not exchange-traded shares) issued by the Fund may convert those shares to ETF Shares of equivalent value of the same fund. Please note that investors who own conventional shares through a 401(k) plan or other employer-sponsored retirement or benefit plan generally may not convert those shares to ETF Shares and should check with their plan sponsor or recordkeeper. ETF Shares, whether acquired through a conversion or purchased on the secondary market, cannot be converted to conventional shares. Also, ETF Shares of one fund cannot be exchanged for ETF Shares of another fund.

ETF Shares must be held in a brokerage account. Thus, before converting conventional shares to ETF Shares, you must have an existing, or open a new, brokerage account. This account may be with Vanguard Brokerage Services ^® (Vanguard Brokerage) or with any other brokerage firm.

Vanguard Brokerage does not impose a fee on conversions from conventional shares to Vanguard ETF Shares. However, other brokerage firms may charge a fee to process a conversion. Vanguard reserves the right, in the future, to impose a transaction fee on conversions or to limit or terminate the conversion privilege. For additional information on converting conventional shares to ETF Shares, please contact Vanguard to obtain a prospectus for ETF Shares. See Contacting Vanguard .

Mandatory Conversions to Another Share Class

If an account no longer meets the balance requirements for a share class, Vanguard may automatically convert the shares in the account to another share class, as appropriate. A decline in the account balance because of market movement may result in such a conversion. Vanguard will notify the investor in writing before any mandatory conversion occurs.

Redeeming Shares

How to Initiate a Redemption Request

Be sure to check Exchanging Shares, Frequent-Trading Limitations , and Other Rules You Should Know before placing your redemption request.

Online. You may request a redemption of shares or request an exchange through our website or our mobile application if you are registered for online access.

By telephone. You may call Vanguard to request a redemption of shares or an exchange. See Contacting Vanguard .

By mail. You may send a written request to Vanguard to redeem from a fund account or to make an exchange. See Contacting Vanguard .

How to Receive Redemption Proceeds

By electronic bank transfer. You may have the proceeds of a fund redemption sent directly to a designated bank account. To establish the electronic bank transfer option on an account, you must designate a bank account online, complete a special form, or fill out the appropriate section of your account registration form. After the option is set up on your account, you can redeem shares by electronic bank transfer on a regular schedule (Automatic Withdrawal Plan) or from time to time. Your redemption request can be initiated online (if you are registered for online access), by telephone, or by mail.

By wire. To receive your proceeds by wire, you may instruct Vanguard to wire your redemption proceeds ($100 minimum) to a previously designated bank account. To establish the wire redemption option, you generally must designate a bank account online, complete a special form, or fill out the appropriate section of your account registration form.

By exchange. You may have the proceeds of a Vanguard fund redemption invested directly in shares of another Vanguard fund. You may initiate an exchange online (if you are registered for online access), by telephone, or by written request. See Exchanging Shares .

By check. If you have not chosen another redemption method, Vanguard will mail you a redemption check, generally payable to all registered account owners, normally within two business days of your trade date, and generally to the address of record.

Trade Date

The trade date for any redemption request received in good order will depend on the day and time Vanguard receives your request and the manner in which you are redeeming. Your redemption will be executed using the NAV as calculated on the trade date. NAVs are calculated only on days that the NYSE is open for trading (a business day).

For redemptions by check , exchange , or wire : If the redemption request is received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the trade date will be the same day. If the redemption request is received on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date will be the next business day.

• Note on timing of wire redemptions from money market funds: For telephone requests received by Vanguard on a business day before 10:45 a.m., Eastern time (2 p.m., Eastern time, for Vanguard Prime Money Market Fund), the redemption proceeds generally will leave Vanguard by the close of business the same day. For telephone requests received by Vanguard on a business day after those cut-off times, or on a nonbusiness day, and for all requests other than by telephone, the redemption proceeds generally will leave Vanguard by the close of business on the next business day.

• Note on timing of wire redemptions from all other funds: For requests received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the redemption proceeds generally will leave Vanguard by the close of business on the next business day. For requests received by Vanguard on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the redemption proceeds generally will leave Vanguard by the close of business on the second business day after Vanguard receives the request.

For redemptions by electronic bank transfer using an Automatic Withdrawal Plan : Your trade date generally will be the date you designated for withdrawal of funds (redemption of shares) from your Vanguard account. Proceeds of redeemed shares generally will be credited to your designated bank account two business days after your trade date. If the date you designated for withdrawal of funds from your

Vanguard account falls on a weekend, holiday, or other nonbusiness day, your trade date generally will be the previous business day.

For redemptions by electronic bank transfer not using an Automatic Withdrawal Plan: If the redemption request is received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the trade date will be the same day. If the redemption request is received on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date will be the next business day.

If your redemption request is not accurate and complete, it may be rejected. If we are unable to send your redemption proceeds by wire or electronic bank transfer because the receiving institution rejects the transfer, Vanguard will make additional efforts to complete your transaction. If Vanguard is still unable to complete the transaction, we may send the proceeds of the redemption to you by check, generally payable to all registered account owners, or use your proceeds to purchase new shares of the fund from which you sold shares for the purpose of the wire or electronic bank transfer transaction. See Other Rules You Should Know—Good Order .

For further information about redemption transactions, consult our website at vanguard.com or see Contacting Vanguard .

Other Redemption Rules You Should Know

Documentation for certain accounts. Special documentation may be required to redeem from certain types of accounts, such as trust, corporate, nonprofit, or retirement accounts. Please call us before attempting to redeem from these types of accounts.

Potentially disruptive redemptions. Vanguard reserves the right to pay all or part of a redemption in kind—that is, in the form of securities—if we reasonably believe that a cash redemption would negatively affect the fund’s operation or performance or that the shareholder may be engaged in market-timing or frequent trading. Under these circumstances, Vanguard also reserves the right to delay payment of the redemption proceeds for up to seven calendar days. By calling us before you attempt to redeem a large dollar amount, you may avoid in-kind or delayed payment of your redemption. Please see Frequent-Trading Limitations for information about Vanguard’s policies to limit frequent trading.

Recently purchased shares. Although you can redeem shares at any time, proceeds may not be made available to you until the fund collects payment for your purchase. This may take up to seven calendar days for shares purchased by check or by electronic bank transfer. If you have written a check on a fund with checkwriting privileges, that check may be rejected if your fund account does not have a sufficient available balance.

Address change. If you change your address online or by telephone, there may be up to a 14-day restriction on your ability to request check redemptions online and by telephone. You can request a redemption in writing at any time. Confirmations of address changes are sent to both the old and new addresses.

Payment to a different person or address. At your request, we can make your redemption check payable, or wire your redemption proceeds, to a different person or send it to a different address. However, this generally requires the written consent of all registered account owners and may require a signature guarantee or a notarized signature. You may obtain a signature guarantee from some commercial or savings banks, credit unions, trust companies, or member firms of a U.S. stock exchange.

No cancellations. Vanguard will not accept your request to cancel any redemption request once processing has begun. Please be careful when placing a redemption request.

Emergency circumstances. Vanguard funds can postpone payment of redemption proceeds for up to seven calendar days. In addition, Vanguard funds can suspend redemptions and/or postpone payments of redemption proceeds beyond seven calendar days at times when the NYSE is closed or during emergency circumstances, as determined by the SEC.

Exchanging Shares

An exchange occurs when you use the proceeds from the redemption of shares of one Vanguard fund to simultaneously purchase shares of a different Vanguard fund. You can make exchange requests online (if you are registered for online access), by telephone, or by written request. See Purchasing Shares and Redeeming Shares .

If the NYSE is open for regular trading (generally until 4 p.m., Eastern time, on a business day) at the time an exchange request is received in good order, the trade date generally will be the same day. See Other Rules You Should Know—Good Order for additional information on all transaction requests.

Vanguard will not accept your request to cancel any exchange request once processing has begun. Please be careful when placing an exchange request.

Please note that Vanguard reserves the right, without notice, to revise or terminate the exchange privilege, limit the amount of any exchange, or reject an exchange, at any time, for any reason. See Frequent-Trading Limitations for additional restrictions on exchanges.

Frequent-Trading Limitations

Because excessive transactions can disrupt management of a fund and increase the fund’s costs for all shareholders, the board of trustees of each Vanguard fund places

certain limits on frequent trading in the funds. Each Vanguard fund (other than money market funds and short-term bond funds) limits an investor’s purchases or exchanges into a fund account for 60 calendar days after the investor has redeemed or exchanged out of that fund account. ETF Shares are not subject to these frequent-trading limits.

For Vanguard Retirement Investment Program pooled plans, the limitations apply to exchanges made online or by telephone.

These frequent-trading limitations do not apply to the following:

• Purchases of shares with reinvested dividend or capital gains distributions.

• Transactions through Vanguard’s Automatic Investment Plan, Automatic Exchange Service, Direct Deposit Service, Automatic Withdrawal Plan, Required Minimum Distribution Service, and Vanguard Small Business Online ^® .

• Redemptions of shares to pay fund or account fees.

• Redemptions of shares to remove excess shareholder contributions to certain types of retirement accounts (including, but not limited to, IRAs, certain Individual 403(b)(7) Custodial Accounts, and Vanguard Individual 401(k) Plans).

• Transaction requests submitted by mail to Vanguard from shareholders who hold their accounts directly with Vanguard or through a Vanguard brokerage account. (Transaction requests submitted by fax, if otherwise permitted, are subject to the limitations.)

• Transfers and reregistrations of shares within the same fund.

• Purchases of shares by asset transfer or direct rollover.

• Conversions of shares from one share class to another in the same fund.

• Checkwriting redemptions.

• Section 529 college savings plans.

• Certain approved institutional portfolios and asset allocation programs, as well as trades made by Vanguard funds that invest in other Vanguard funds. (Please note that shareholders of Vanguard’s funds of funds are subject to the limitations.)

For participants in employer-sponsored defined contribution plans,* the frequent-trading limitations do not apply to:

• Purchases of shares with participant payroll or employer contributions or loan repayments.

• Purchases of shares with reinvested dividend or capital gains distributions.

• Distributions, loans, and in-service withdrawals from a plan.

• Redemptions of shares as part of a plan termination or at the direction of the plan.

• Automated transactions executed during the first six months of a participant’s enrollment in the Vanguard Managed Account Program.

Redemptions of shares to pay fund or account fees.
Share or asset transfers or rollovers.
Reregistrations of shares.
Conversions of shares from one share class to another in the same fund.
Exchange requests submitted by written request to Vanguard. (Exchange requests

submitted by fax, if otherwise permitted, are subject to the limitations.)

* The following Vanguard fund accounts are subject to the frequent-trading limitations: SEP-IRAs, SIMPLE IRAs, certain Individual 403(b)(7) Custodial Accounts, and Vanguard Individual 401(k) Plans.

Accounts Held by Institutions (Other Than Defined Contribution Plans)

Vanguard will systematically monitor for frequent trading in institutional clients’ accounts. If we detect suspicious trading activity, we will investigate and take appropriate action, which may include applying to a client’s accounts the 60-day policy previously described, prohibiting a client’s purchases of fund shares, and/or revoking the client’s exchange privilege.

Accounts Held by Intermediaries

When intermediaries establish accounts in Vanguard funds for the benefit of their clients, we cannot always monitor the trading activity of the individual clients. However, we review trading activity at the intermediary (omnibus) level, and if we detect suspicious activity, we will investigate and take appropriate action. If necessary, Vanguard may prohibit additional purchases of fund shares by an intermediary, including for the benefit of certain of the intermediary’s clients. Intermediaries also may monitor their clients’ trading activities with respect to Vanguard funds.

For those Vanguard funds that charge purchase and/or redemption fees, intermediaries will be asked to assess these fees on client accounts and remit these fees to the funds. The application of purchase and redemption fees and frequent-trading limitations may vary among intermediaries. There are no assurances that Vanguard will successfully identify all intermediaries or that intermediaries will properly assess purchase and redemption fees or administer frequent-trading limitations. If you invest with Vanguard through an intermediary, please read that firm’s materials carefully to learn of any other rules or fees that may apply.

The account service fee applies to both retirement and nonretirement fund accounts and will be assessed on fund accounts in all Vanguard funds, regardless of a fund’s minimum initial investment amount. The fee, which will be collected by redeeming fund shares in the amount of $20, will be deducted from a fund account only once per calendar year.

If you register on vanguard.com and elect to receive electronic delivery of statements, reports, and other materials for all of your fund accounts, the account service fee for balances below $10,000 will not be charged, so long as that election remains in effect.

The account service fee also does not apply to the following:

• Money market sweep accounts owned in connection with a Vanguard Brokerage Services ^® account.

Accounts held through intermediaries.
Accounts held by Voyager, Voyager Select, and Flagship clients. Eligibility is based

on total household assets held at Vanguard, with a minimum of $50,000 to qualify for Vanguard Voyager Services ^® , $500,000 for Vanguard Voyager Select Services ^® , and $1 million for Vanguard Flagship Services ^® . Vanguard determines eligibility by aggregating assets of all qualifying accounts held by the investor and immediate family members who reside at the same address. Aggregate assets include investments in Vanguard mutual funds, Vanguard ETFs ^® , certain annuities through Vanguard, the Vanguard 529 Plan, and certain small-business accounts. Assets in

employer-sponsored retirement plans for which Vanguard provides recordkeeping services may be included in determining eligibility if the investor also has a personal account holding Vanguard mutual funds. Note that assets held in a Vanguard Brokerage Services account (other than Vanguard funds, including Vanguard ETFs) are not included when determining a household’s eligibility.

• Participant accounts in employer-sponsored defined contribution plans.* Please consult your enrollment materials for the rules that apply to your account.

Section 529 college savings plans.
The following Vanguard fund accounts have alternative fee structures: SIMPLE IRAs,

certain Individual 403(b)(7) Custodial Accounts, Vanguard Retirement Investment Program pooled plans, and Vanguard Individual 401(k) Plans.

Low-Balance Accounts

The Fund reserves the right to liquidate a fund account whose balance falls below the minimum initial investment for any reason, including market fluctuation. This policy applies to nonretirement fund accounts and accounts that are held through intermediaries.

Right to Change Policies

In addition to the rights expressly stated elsewhere in this prospectus, Vanguard reserves the right, without notice, to (1) alter, add, or discontinue any conditions of purchase (including eligibility requirements), redemption, exchange, conversion, service, or privilege at any time; (2) accept initial purchases by telephone; (3) freeze any account and/or suspend account services if Vanguard has received reasonable notice of a dispute regarding the assets in an account, including notice of a dispute between the registered or beneficial account owners, or if Vanguard reasonably believes a fraudulent transaction may occur or has occurred; (4) temporarily freeze any account and/or suspend account services upon initial notification to Vanguard of the death of the shareholder until Vanguard receives required documentation in good order; (5) alter, impose, discontinue, or waive any purchase fee, redemption fee, account service fee, or other fees charged to a group of shareholders; and (6) redeem an account or suspend account privileges, without the owner’s permission to do so, in cases of threatening conduct or activity Vanguard believes to be suspicious, fraudulent, or illegal. Changes may affect any or all investors. These actions will be taken when, at the sole discretion of Vanguard management, Vanguard reasonably believes they are deemed to be in the best interest of a fund.

Share Classes

Vanguard reserves the right, without notice, to change the eligibility requirements of its share classes, including the types of clients who are eligible to purchase each share class.

Glossary of Investment Terms

Bond. A debt security (IOU) issued by a corporation, government, or government agency in exchange for the money you lend it. In most instances, the issuer agrees to pay back the loan by a specific date and generally to make regular interest payments until that date.

Capital Gains Distribution. Payment to mutual fund shareholders of gains realized on securities that a fund has sold at a profit, minus any realized losses.

Coupon. The interest rate paid by the issuer of a debt security until its maturity. It is expressed as an annual percentage of the face value of the security.

Dividend Distribution. Payment to mutual fund shareholders of income from interest or dividends generated by a fund’s investments.

Expense Ratio. A fund’s total annual operating expenses expressed as a percentage of the fund’s average net assets. The expense ratio includes management and administrative expenses, but does not include the transaction costs of buying and selling portfolio securities.

Face Value. The amount to be paid at a bond’s maturity; also known as the par value or principal.

Fixed Income Security. An investment, such as a bond, representing a debt that must be repaid by a specified date, and on which the borrower must pay a fixed, variable, or floating rate of interest.

Float-Adjusted Index. An index that weights its constituent securities based on the value of the constituent securities that are available for public trading, rather than the value of all constituent securities. Some portion of an issuer’s securities may be unavailable for public trading because, for example, those securities are owned by company insiders on a restricted basis or by a government agency. By excluding unavailable securities, float-adjusted indexes can produce a more accurate picture of the returns actually experienced by investors in the measured market.

Inception Date. The date on which the assets of a fund (or one of its share classes) are first invested in accordance with the fund’s investment objective. For funds with a subscription period, the inception date is the day after that period ends. Investment performance is generally measured from the inception date.

Indexing. A low-cost investment strategy in which a mutual fund attempts to track—rather than outperform—a specified market benchmark, or “index.”

Investment-Grade Bond. A debt security whose credit quality is considered by independent bond-rating agencies, or through independent analysis conducted by a fund’s advisor, to be sufficient to ensure timely payment of principal and interest under current economic circumstances. Debt securities rated in one of the four highest rating categories are considered investment-grade. Other debt securities may be considered by an advisor to be investment-grade.

Mutual Fund. An investment company that pools the money of many people and invests it in a variety of securities in an effort to achieve a specific objective over time.

Principal. The face value of a debt instrument or the amount of money put into an investment.

Securities. Stocks, bonds, money market instruments, and other investments.

Total Return. A percentage change, over a specified time period, in a mutual fund’s net asset value, assuming the reinvestment of all distributions of dividends and capital gains.

Volatility. The fluctuations in value of a mutual fund or other security. The greater a fund’s volatility, the wider the fluctuations in its returns.

Yield. Income (interest or dividends) earned by an investment, expressed as a percentage of the investment’s price.

Fund Summary

Investment Objective

The Fund seeks to track the performance of a benchmark index that measures the investment return of non-U.S. dollar-denominated investment-grade bonds.

Fees and Expenses

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


Shareholder Fees
(Fees paid directly from your investment)

Sales Charge (Load) Imposed on Purchases	None
Purchase Fee	None
Sales Charge (Load) Imposed on Reinvested Dividends	None
Redemption Fee	None


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

Management Expenses	0.07%
12b-1 Distribution Fee	None
Other Expenses	0.05%
Total Annual Fund Operating Expenses	0.12%

Example

The following example is intended to help you compare the cost of investing in the Fund’s Institutional 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 total annual fund 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:


1 Year	3 Years
$12	$39

Portfolio Turnover

The Fund has no operating history and therefore has no portfolio turnover information.

Investing in Index Funds

What Is Indexing?

Index funds typically have the following characteristics:

• Variety of investments. Most Vanguard index funds generally invest in the securities of a variety of companies, industries, and government entities.

• Relative performance consistency . Because they seek to track market benchmarks, index funds usually do not perform dramatically better or worse than their benchmarks.

• Low cost . Index funds are inexpensive to run compared with actively managed funds.

They have low or no research costs and typically keep trading activity—and thus dealer markups and other transaction costs—to a minimum.

More on the Fund

Share Class Overview

This prospectus offers the Fund’s Institutional Shares, which are generally for investors who invest a minimum of $5 million. A separate prospectus offers the Fund’s Investor Shares and Admiral™ Shares, which have investment minimums of $3,000 and $10,000, respectively. In addition, the Fund issues an exchange-traded class of shares (ETF Shares) and a Transition Share class, each of which is offered through a separate prospectus. The Transition Share class will only be available to other Vanguard funds.

Plain Talk About Fund Expenses

All mutual funds have operating expenses. These expenses, which are deducted

from a fund’s gross income, are expressed as a percentage of the net assets of

the fund. Assuming that operating expenses remain as stated in the Fees and

Expenses section, Vanguard Total International Bond Index Fund Institutional

Shares’ expense ratio would be 0.12%, or $1.20 per $1,000 of average

net assets.

Plain Talk About Costs of Investing

Costs are an important consideration in choosing a mutual fund. That’s because

you, as a shareholder, pay a proportionate share of the costs of operating a fund,

plus any transaction costs incurred when the fund buys or sells securities. These

costs can erode a substantial portion of the gross income or the capital

appreciation a fund achieves. Even seemingly small differences in expenses can,

over time, have a dramatic effect on a fund’s performance.

The following sections explain the primary investment strategies and policies that the Fund uses in pursuit of its objective. The Fund’s board of trustees, which oversees the Fund’s management, may change investment strategies or policies in the interest of shareholders without a shareholder vote, unless those strategies or policies are designated as fundamental. The Fund‘s policy of investing at least 80% of its assets in securities that are included in its target index may be changed only upon 60 days‘ notice to shareholders. Note that the Fund’s investment objective is not fundamental and may be changed without a shareholder vote.
