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

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 fiscal period from April 5, 2021, to December 31, 2021, the Fund's portfolio turnover rate was 22% of the average value of its portfolio.
Principal Investment Strategies
The Fund invests in a diversified portfolio of high-quality and, to a lesser extent, medium-quality fixed income securities. High-quality fixed income securities are investment-grade securities that are rated the equivalent of A3 or better by Moody‘s Investors Service, Inc. (Moody‘s) or another independent rating agency or, if unrated, are determined to be of comparable quality by the Fund’s advisor. Medium-quality fixed income securities are investment-grade securities that are rated the equivalent of Baa1, Baa2, or Baa3 by Moody‘s or another independent rating agency or, if unrated, are determined to be of comparable quality by the Fund’s advisor. The Fund is expected to maintain a dollar-weighted average maturity of 0 to 2 years. Under normal circumstances, the Fund will invest at least 80% of its assets in fixed income securities.

Principal Risks
The Fund is designed for investors with a low tolerance for risk, but you could still lose money by investing in it. The Fund is subject to the following risks, which could affect the Fund's performance, and the level of risk may vary based on market conditions:
• Income risk, which is the chance that the Fund's income will decline because of falling interest rates. Income risk is generally high for short-term bond funds, so investors should expect the Fund’s monthly income to fluctuate accordingly.
• Interest rate risk, which is the chance that bond prices overall will decline because of rising interest rates.
• Credit risk, which is the chance that a bond issuer will fail to pay interest or 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.
• Liquidity risk, which is the chance that the Fund may not be able to sell a security in a timely manner at a desired price.
• Call risk, which is the chance that during periods of falling interest rates, issuers of callable bonds may call (redeem) securities with higher coupon rates 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.
• Prepayment risk, which is the chance that during periods of falling interest rates, homeowners will refinance their mortgages before their maturity dates, resulting in prepayment of mortgage-backed securities held by the Fund. The Fund would then lose any price appreciation above the mortgage’s principal and would be forced to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the Fund's income. Such prepayments and subsequent reinvestments would also increase the Fund’s portfolio turnover rate.
• Manager risk, which is the chance that poor security selection will cause the Fund to underperform relevant benchmarks or other funds with a similar investment objective.
• Derivatives risk. The Fund may invest in derivatives. In general, investments in derivatives may involve risks different from, and possibly greater than, those of investments directly in the underlying securities or assets.
Because ETF Shares are traded on an exchange, they are subject to additional risks:
• The Fund’s ETF Shares are listed for trading on Cboe BZX Exchange, Inc. and are bought and sold on the secondary market at market prices. Although it is
3

expected that the market price of an ETF Share typically will approximate its net asset value (NAV), there may be times when the market price and the NAV differ significantly. Thus, you may pay more or less than NAV when you buy ETF Shares on the secondary market, and you may receive more or less than NAV when you sell those shares.
• Although the Fund’s ETF Shares are listed for trading on Cboe BZX Exchange, Inc., it is possible that an active trading market may not be maintained, which could increase the Fund’s risks as disclosed in this prospectus.
• Trading of the Fund’s ETF Shares may be halted by the activation of individual or marketwide trading halts (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). Trading of the Fund’s ETF Shares may also be halted if (1) the shares are delisted from Cboe BZX Exchange, Inc. without first being listed on another exchange or (2) Cboe BZX Exchange, Inc. officials determine that such action is appropriate in the interest of a fair and orderly market or for the protection of investors.
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.

Purchase and Sale of Fund Shares
ETF Shares may only be bought and sold in the secondary market through a brokerage firm. The price you pay or receive for ETF Shares will be the prevailing market price, which may be more (premium) or less (discount) than the NAV of the shares. The brokerage firm may charge you a commission to execute the transaction. Unless imposed by your brokerage firm, there is no minimum dollar amount you must invest and no minimum number of shares you must buy. ETF Shares cannot be directly purchased from or redeemed with the Fund, except by certain authorized broker-dealers. These broker-dealers may purchase and redeem ETF Shares only in large blocks (Creation Units), typically in exchange for baskets of securities.


An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase ETF Shares (bid) and the lowest price a seller is willing to accept for ETF Shares (ask) when buying or selling shares in the secondary market (bid-ask spread). Recent information, including information on the Fund's NAV, market price, premiums and discounts, and bid-ask spreads, is available online at vanguard.com.
Tax Information
The Fund’s distributions may be taxable as ordinary income or capital gain. Additionally, the Fund may also make distributions that are treated as a return of capital. If you are investing through a tax-advantaged account, such as an IRA or an employer-sponsored retirement or savings plan, special tax rules apply.
Payments to Financial Intermediaries
The Fund and its investment advisor do not pay financial intermediaries for sales of Fund shares.

Investing in Vanguard ETF® Shares
What Are Vanguard ETF Shares?
Vanguard ETF Shares are an exchange-traded class of shares issued by certain Vanguard funds. ETF Shares represent an interest in the portfolio of stocks or bonds held by the issuing fund.
How Are Vanguard ETF Shares Different From Conventional Mutual Fund Shares?
Conventional mutual fund shares can be directly purchased from and redeemed with the issuing fund for cash at the net asset value (NAV), typically calculated once a day. ETF Shares, by contrast, cannot be purchased directly from or redeemed directly with the issuing fund by an individual investor. Rather, ETF Shares can only be purchased or redeemed directly from the issuing fund by certain authorized broker-dealers. These broker-dealers may purchase and redeem ETF Shares only in large blocks (Creation Units), usually in exchange for baskets of securities and not for cash (although some funds issue and redeem Creation Units in exchange for cash or a combination of cash and securities).
An organized secondary trading market is expected to exist for ETF Shares, unlike conventional mutual fund shares, because ETF Shares are listed for trading on a national securities exchange. Individual investors can purchase and sell ETF Shares on the secondary market through a broker. Secondary-market transactions occur not at NAV, but at market prices that are subject to change throughout the day based on the supply of and demand for ETF Shares, changes in the prices of the fund’s portfolio holdings, and other factors.
The market price of ETF Shares typically will differ somewhat from the NAV of those shares. The difference between market price and NAV is expected to be small most of the time, but in times of market disruption or extreme market volatility, the difference may become significant.

How Do I Buy and Sell Vanguard ETF Shares?
ETF Shares of the Fund are listed for trading on Cboe BZX Exchange, Inc.. You can buy and sell ETF Shares on the secondary market in the same way you buy and sell any other exchange-traded security—through a broker. Your broker may charge a commission to execute a transaction. You will also incur the cost of the “bid-ask spread,” which is the difference between the highest price a buyer is willing to pay to purchase ETF Shares (bid) and the lowest price a seller is willing to accept for ETF Shares (ask) when buying or selling shares in the secondary market. Because secondary-market transactions occur at market prices, you may pay more (premium) or less (discount) than NAV when you buy ETF Shares and receive more or less than NAV when you sell those shares. In times of severe market disruption, the bid-ask spread and premiums/discounts can increase significantly. Unless imposed by your broker, there is no minimum dollar amount you must invest and no minimum number of ETF Shares you must buy.
Your ownership of ETF Shares will be shown on the records of the broker through which you hold the shares. Vanguard will not have any record of your ownership. Your account information will be maintained by your broker, which will provide you with account statements, confirmations of your purchases and sales of ETF Shares, and tax information. Your broker also will be responsible for ensuring that you receive income and capital gains distributions, as well as shareholder reports and other communications from the fund whose ETF Shares you own. You will receive other services (e.g., dividend reinvestment and average cost information) only if your broker offers these services.

More on the Fund and ETF Shares
This prospectus describes the principal risks you would face as a Fund shareholder. It is important to keep in mind one of the main principles 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 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 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.
A Similar but Distinct Vanguard Fund
The Fund offered by this prospectus is not an ETF Share class of Vanguard Ultra-Short-Term Bond Fund and should not be confused with Vanguard Ultra-Short-Term Bond Fund, a separate Vanguard fund that shares a similar investment strategy. Differences in scale and in underlying holdings are expected to produce slightly different investment returns by the funds. To obtain a prospectus for Vanguard Ultra-Short-Term Bond Fund, please call 800-662-7447.
A Note to Investors
Vanguard ETF Shares can be purchased directly from the issuing Fund only by certain authorized broker-dealers in exchange for a basket of securities (or, in some cases, for cash or a combination of cash and securities). Individual investors generally will not be able to purchase ETF Shares directly from the Fund. Instead, these investors will purchase ETF Shares on the secondary market through a broker.
Plain Talk About Fund Expenses
All 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 Ultra-Short Bond ETF's expense ratio would
be 0.10%, or $1.00 per $1,000 of average net assets. The average expense
ratio for short investment grade debt funds in 2021 was 0.66%, or $6.60 per
$1,000 of average net assets (derived from data provided by Lipper, a
Thomson Reuters Company, which reports on the fund industry).

Plain Talk About Costs of Investing
Costs are an important consideration in choosing an ETF. That is because
you, as a shareholder, pay a proportionate share of the costs of operating a
fund and 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 principal investment strategies and policies that the Fund uses in pursuit of its investment 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. Note that the Fund’s investment objective is not fundamental and may be changed without a shareholder vote. However, the Fund may change its policy of investing at least 80% of its assets in fixed income securities only upon 60 days‘ notice to shareholders.
Market Exposure
The Fund invests mainly in bonds. As a result, it is subject to certain risks.
The Fund is subject to interest rate risk, which is the chance that bond prices will decline because of rising interest rates.
Although fixed income securities (commonly referred to as 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 long-term bonds fell by almost 48% between December 1976 and September 1981.
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 (i.e., bonds that cannot be redeemed by the issuer) of different maturities, each with a face value of $1,000.

1 Assuming a 4% coupon rate.
These figures are for illustration only; you should not regard them as an indication of future performance of the bond market as a whole 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.
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 high for short-term bond funds, so investors should expect the Fund‘s monthly income to fluctuate accordingly.
10

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, will face as interest rates
rise—but also the higher the potential yield you could receive. Longer-term
bonds are generally 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. The stated maturity of a bond may differ from the effective
maturity of a bond, which takes into consideration that an action such as a
call or refunding may cause bonds to be repaid before their stated
maturity dates.
Although falling interest rates tend to strengthen bond prices, they can cause other 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 coupon rates 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.
The Fund is subject to prepayment risk, which is the chance that during periods of falling interest rates, homeowners will refinance their mortgages before their maturity dates, resulting in prepayment of mortgage-backed securities held by the Fund. The Fund would then lose any price appreciation above the mortgage's principal and would be forced to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the Fund's income. Such prepayments and subsequent reinvestments would also increase the Fund's portfolio turnover rate.
11

Plain Talk About Callable Bonds
Although bonds are issued with clearly defined maturities, in some cases the
bond issuer has a right to call in (redeem) the bond earlier than its maturity
date. When a bond is called, the bondholder may have to replace it with
another bond with a lower yield than the original bond. One way for bond
investors to protect themselves against call risk is to purchase a bond early
in its lifetime, long before its call date. Another way is to buy bonds with
lower coupon rates or interest rates, which make them less likely to
be called.
The Fund is subject to credit risk, which is the chance that a bond issuer will fail to pay interest or 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.
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. The lower the
credit quality, the greater the perceived chance that the bond issuer will
default, or fail to meet its payment obligations. All things being equal, the
lower a bond’s credit quality, the higher its yield should be to compensate
investors for assuming additional risk.
The Fund is subject to liquidity risk, which is the chance that the Fund may not be able to sell a security in a timely manner at a desired price.
Corporate bonds are traded among dealers and brokers that connect buyers with sellers. Liquidity in the corporate bond market may be challenged depending on overall economic conditions and credit tightening. There may be little trading in the secondary market for particular bonds and other debt securities, which may make them more difficult to value or sell.
To a limited extent, the Fund is also indirectly subject to event risk, which is the chance that corporate fixed income securities held by the Fund may suffer a substantial decline in credit quality and market value because of a restructuring of the companies that issued the securities or because of other factors negatively affecting issuers.
12

Plain Talk About Types of Bonds
Bonds are issued (sold) by many sources: Corporations issue corporate
bonds; the federal government issues U.S. Treasury bonds; agencies of the
federal government issue agency bonds; financial institutions issue
asset-backed bonds; and mortgage holders issue “mortgage-backed”
pass-through certificates. Each issuer is responsible for paying back the
bond’s initial value as well as for making periodic interest payments. Many
bonds issued by government agencies and entities are neither guaranteed
nor insured by the U.S. government.
Market disruptions can adversely affect local and global markets as well as normal market conditions and operations. Any such disruptions could have an adverse impact on the value of the Fund's investments and Fund performance.
Security Selection
Vanguard’s actively managed fixed income funds follow a portfolio manager-driven process that uses both top-down and bottom-up inputs. Portfolio managers are responsible for portfolio construction and strategy, leveraging the top-down insights of Vanguard's senior investment leaders and Vanguard's Investment Strategy Group, the bottom-up insights of the sector teams, and the relative value views across fixed income sectors. Risk optimization measures are present throughout the investment process, and the Senior Investment Committee provides governance and oversight for the entire lineup.
The types of financial instruments that may be purchased by the Fund are identified and explained as follows:
U.S. government and agency bonds represent loans by investors to the U.S. Treasury or a wide variety of government agencies and instrumentalities. Securities issued by most U.S. government entities are neither guaranteed by the U.S. Treasury nor backed by the full faith and credit of the U.S. government. These entities include, among others, the Federal Home Loan Banks (FHLBs), the Federal National Mortgage Association (FNMA), and the Federal Home Loan Mortgage Corporation (FHLMC). Securities issued by the U.S. Treasury and a small number of U.S. government agencies, such as the Government National Mortgage Association (GNMA), are backed by the full faith and credit of the U.S. government. The market values of U.S. government and agency securities and U.S. Treasury securities are subject to fluctuation.
13

Plain Talk About U.S. Government-Sponsored Enterprises
A variety of U.S. government-sponsored enterprises (GSEs), such as the
Federal Home Loan Mortgage Corporation (FHLMC), the Federal National
Mortgage Association (FNMA), and the Federal Home Loan Banks (FHLBs),
issue debt and mortgage-backed securities. Although GSEs may be chartered
or sponsored by acts of Congress, they are not funded by congressional
appropriations. In September of 2008, the U.S. Treasury placed FNMA and
FHLMC under conservatorship and appointed the Federal Housing Finance
Agency (FHFA) to manage their daily operations. In addition, the U.S. Treasury
entered into purchase agreements with FNMA and FHLMC to provide them
with capital in exchange for senior preferred stock. Generally, a GSE’s
securities are neither issued nor guaranteed by the U.S. Treasury and are not
backed by the full faith and credit of the U.S. government. In most cases,
these securities are supported only by the credit of the GSE, standing alone. In
some cases, a GSE’s securities may be supported by the ability of the GSE to
borrow from the U.S. Treasury or may be supported by the U.S. government in
some other way. Securities issued by the Government National Mortgage
Association (GNMA), however, are backed by the full faith and credit of the
U.S. government.
• Cash equivalent investments is a blanket term that describes a variety of short-term fixed income investments, including money market instruments, commercial paper, bank certificates of deposit, banker’s acceptances, and repurchase agreements. Repurchase agreements represent short-term (normally overnight) loans by a fund to banks or large securities dealers. Repurchase agreements can carry several risks. For instance, if the seller is unable to repurchase the securities as promised, a fund may experience a loss when trying to sell the securities to another buyer. Also, if the seller becomes insolvent, a bankruptcy court may determine that the securities do not belong to a fund and order that the securities be used to pay off the seller’s debts. The Fund’s advisor believes that these risks can be controlled through careful security selection and monitoring.
• Corporate debt obligations—usually called bonds—represent loans by an investor to a corporation.
• Asset-backed securities are bonds that represent partial ownership in pools of consumer or commercial loans—most often credit card, automobile, or trade receivables. Asset-backed securities, which can be types of corporate fixed income obligations, are issued by entities formed solely for that purpose, but
14

their value ultimately depends on repayments by underlying borrowers. A primary risk of asset-backed securities is that their maturity is difficult to predict, being driven by borrowers’ prepayments.
• Mortgage-backed securities represent partial ownership interest in pools of commercial or residential mortgage loans made by financial institutions to finance a borrower’s real estate purchase. These loans are packaged by private or governmental issuers for sale to investors. As the underlying mortgage loans are paid by borrowers, the investors receive payments of interest and principal. To be announced (TBA) securities represent an agreement to buy or sell mortgage-backed securities with agreed-upon characteristics for a fixed unit price, with settlement on a scheduled future date beyond the typical settlement period for most other securities.
• International dollar-denominated bonds are bonds denominated in U.S. dollars and issued by foreign governments and companies. To the extent that the Fund owns foreign bonds, it is subject to country risk, which is the chance that world events—such as political upheaval, financial troubles, or natural disasters—will adversely affect the value and/or liquidity of securities issued by companies in foreign countries. In addition, the prices of foreign bonds and the prices of U.S. bonds have, at times, moved in opposite directions. Because the bond’s value is designated in dollars rather than in the currency of the issuer’s country, the investor is not exposed to currency risk; rather, the issuer assumes that risk, usually to attract U.S. investors. Although currency movements do not affect the value of international dollar-denominated bonds directly, they could affect the value indirectly by adversely affecting the issuer’s ability (or the market’s perception of the issuer’s ability) to pay interest or repay principal.
• Foreign currency bonds are bonds denominated in the local currency of a non-U.S. country and issued by foreign governments, government agencies, and companies. To the extent that the Fund owns foreign currency bonds, it will hedge its exposure to those bonds back to the U.S. dollar. In addition to country risk, the Fund is subject to currency hedging risk. Currency hedging risk is the chance that the currency hedging transactions entered into by a Fund may not perfectly offset the Fund’s foreign currency exposure.
• Preferred stocks distribute set dividends from the issuer. The preferred-stock holder’s claim on the issuer’s income and assets ranks before that of common-stock holders, but after that of bondholders.
• Futures, options, and other derivatives are described in detail under Other Investment Policies and Risks.
The Fund is subject to manager risk, which is the chance that poor security selection will cause the Fund to underperform relevant benchmarks or other funds with a similar investment objective.
15

Other Investment Policies and Risks
In addition to investing in bonds and other fixed income securities, the Fund may make other kinds of investments to achieve its investment objective.
The Fund may invest up to 15% of its net assets in illiquid securities. Illiquid securities are investments that a fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment. Restricted securities are a special type of illiquid security; these securities have not been publicly issued and legally can be resold only to qualified buyers.
The Fund may invest a small portion of its assets in fixed income futures, which are a type of derivative, and/or shares of ETFs. These fixed income futures and ETFs typically provide returns similar to those of bonds and may purchase futures or ETFs when doing so will reduce the Fund’s transaction costs, facilitate cash management, mitigate risk, or have the potential to 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.
The Fund may invest in derivatives. In general, investments in derivatives may involve risks different from, and possibly greater than, those of investments directly in the underlying securities or assets.

Generally speaking, a derivative is a financial contract whose value is based on the value of a financial asset (such as a stock, a bond, or a currency), a physical asset (such as gold, oil, or wheat), a market index, or a reference rate. 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 to accomplish one or more of the following:
• 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.
• Adjust the overall credit risk of the portfolio or actively overweight or underweight credit risk to specific bond issuers.
• Hedge foreign currency exposure.
16

• Hedge foreign interest rate exposure.
The Fund's derivative investments may include fixed income futures contracts; fixed income options, including options on swaps; currency swaps; foreign currency exchange forwards; 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.
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. On the
other hand, non-exchange-traded derivatives—such as certain swap
agreements and foreign currency exchange forward contracts—tend to be
more specialized or complex and may be more difficult to accurately value.
Cash Management
The Fund's daily cash balance may be invested in Vanguard Market Liquidity Fund and/or Vanguard Municipal Cash Management Fund (each, a CMT Fund), which are low-cost money market funds. When investing in a CMT Fund, the Fund bears its proportionate share of the expenses of the CMT Fund in which it invests. Vanguard receives no additional revenue from Fund assets invested in a CMT Fund.
Methods Used to Meet Redemption Requests
Redemptions of ETF Shares are typically met through a combination of cash and securities held by the Fund; see “How Are Vanguard ETF Shares Different From Conventional Mutual Fund Shares?” If cash is used to meet redemptions, the Fund typically obtains such cash through positive cash flows or the sale of Fund holdings consistent with the Fund’s investment objective and strategy. Please consult the Fund's Statement of Additional Information for further information on redemptions of ETF Shares.
17

Under certain circumstances, the Fund may borrow money (subject to certain regulatory conditions and if available under board-approved procedures) through an interfund lending facility; through a bank line-of-credit, including a joint committed credit facility; or through an uncommitted line-of-credit from Vanguard in order to meet redemption requests.
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 strategy or policy employed 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 investment objective when those instruments are more favorably priced or provide needed liquidity, as might be the case when the Fund is transitioning assets from one advisor to another or receives large cash flows that it cannot prudently invest immediately.
In addition, the Fund may take temporary defensive positions that are inconsistent with its normal investment policies and strategies—for instance, by allocating substantial assets to cash equivalent investments or other less volatile instruments—in response to adverse or unusual market, economic, political, or other conditions. In doing so, the Fund may succeed in avoiding losses but may otherwise fail to achieve its investment objective.
Special Risks of Exchange-Traded Shares
ETF Shares are not individually redeemable. They can be redeemed with the issuing Fund at NAV only by certain authorized broker-dealers and only in large blocks known as Creation Units. Consequently, if you want to liquidate some or all of your ETF Shares, you must sell them on the secondary market at prevailing market prices.
The market price of ETF Shares may differ from NAV. Although it is expected that the market price of an ETF Share typically will approximate its NAV, there may be times when the market price and the NAV differ significantly. Thus, you may pay more (premium) or less (discount) than NAV when you buy ETF Shares on the secondary market, and you may receive more or less than NAV when you sell those shares. These discounts and premiums are likely to be greatest during times of market disruption or extreme market volatility.
Vanguard’s website at vanguard.com shows the previous day’s closing NAV and closing market price for the Fund. The website also discloses, in the Premium/Discount Analysis section of the Fund’s Price & Performance page,
18

how frequently the Fund traded at a premium or discount to NAV (based on closing NAVs and market prices) and the magnitudes of such premiums and discounts.
An active trading market may not exist. Although Vanguard ETF Shares are listed on a national securities exchange, it is possible that an active trading market may not be maintained. Although this could happen at any time, it is more likely to occur during times of severe market disruption. If you attempt to sell your ETF Shares when an active trading market is not functioning, you may have to sell at a significant discount to NAV. In extreme cases, you may not be able to sell your shares at all.
Trading may be halted. Trading of Vanguard ETF Shares on an exchange may be halted by the activation of individual or marketwide trading halts (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). Trading of ETF Shares may also be halted if (1) the shares are delisted from the listing exchange without first being listed on another exchange or (2) exchange officials determine that such action is appropriate in the interest of a fair and orderly market or for the protection of investors.
A precautionary note to investment companies: Vanguard ETF Shares are issued by registered investment companies, and therefore the acquisition of such shares by other investment companies is subject to the restrictions of Section 12(d)(1) of the Investment Company Act of 1940. Vanguard has obtained SEC exemptive orders that allow investment companies to invest in the issuing funds beyond the limits of Section 12(d)(1), subject to certain terms and conditions, including the requirement to enter into a participation agreement with Vanguard. The SEC recently adopted changes to the regulatory framework for fund of funds arrangements, and, as a result, Vanguard's exemptive orders were rescinded by the SEC on January 19, 2022. However, effective January 19, 2022, new Rule 12d1-4 under the Investment Company Act of 1940 permits registered investment companies to invest in other registered investment companies beyond the limits in Section 12(d)(1), subject to certain conditions, including that the funds enter into a fund of funds investment agreement.
Shareholder Rights
The Fund's Agreement and Declaration of Trust, as amended, requires a shareholder bringing a derivative action on behalf of Vanguard Bond Index Funds (the Trust) that is subject to a pre-suit demand to collectively hold at least 10% of the outstanding shares of the Trust or at least 10% of the outstanding shares of the series or class to which the demand relates and to undertake to reimburse the Trust for the expense of any counsel or advisors used when considering the merits of the demand in the event that the board of trustees determines not to
19

bring such action. In each case, these requirements do not apply to claims arising under the federal securities laws to the extent that any such federal securities laws, rules, or regulations do not permit such application.
Frequent Trading and Market-Timing
Unlike frequent trading of a Vanguard fund’s conventional (i.e., not exchange-traded) classes of shares, frequent trading of ETF Shares does not disrupt portfolio management or otherwise harm fund shareholders. The vast majority of trading in ETF Shares occurs on the secondary market. Because these trades do not involve the issuing fund, they do not harm the fund or its shareholders. Certain broker-dealers are authorized to purchase and redeem ETF Shares directly with the issuing fund. Because these trades typically are effected in kind (i.e., for securities and not for cash), or are assessed a transaction fee when effected in cash, they do not cause any of the harmful effects to the issuing fund (as previously noted) that may result from frequent trading. For these reasons, the board of trustees of each fund that issues ETF Shares has determined that it is not necessary to adopt policies and procedures to detect and deter frequent trading and market-timing of ETF Shares.
Portfolio Holdings
Please consult the Fund's Statement of Additional Information or our website for a description of the policies and procedures that govern disclosure of the Fund’s portfolio holdings.
Turnover Rate
Although the Fund generally seeks to invest for the long term, it may sell securities regardless of how long they have been held. The Financial Highlights section of this prospectus shows the turnover rate for the Fund. A turnover rate of 100%, for example, would mean that the Fund had sold and replaced securities valued at 100% of its net assets within a one-year period. In general, the greater the turnover rate, the greater the impact transaction costs will have on a fund’s return. Also, funds with high turnover rates may be more likely to generate capital gains, including short-term capital gains, that must be distributed to shareholders and will be taxable to shareholders investing through a taxable account.
The Fund and Vanguard
The Fund is a member of The Vanguard Group, Inc. (Vanguard), a family of over 200 funds. All of the funds that are members of Vanguard (other than funds of funds) share in the expenses associated with administrative services and business operations, such as personnel, office space, and equipment.
20

Vanguard Marketing Corporation provides marketing services to the funds. Although fund 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
Vanguard 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 are owned by third parties—either public or
private stockholders—and not by the funds they serve.
Investment Advisor
The Vanguard Group, Inc., 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 December 31, 2021, Vanguard served as advisor for approximately $6.9 trillion in assets. Vanguard provides investment advisory services to the Fund pursuant to the Funds’ Service Agreement and subject to the supervision and oversight of the trustees and officers of the Fund.
Although the Fund is managed solely by Vanguard, the Fund reserves the right to utilize a multi-manager approach in the future. Under the terms of an SEC exemption, the Fund's board of trustees may, without prior approval from shareholders, change the terms of an advisory agreement with a third-party investment advisor or hire a new third-party investment advisor—either as a replacement for an existing advisor or as an additional advisor. Any significant change in the Fund's advisory arrangements will be communicated to shareholders in writing. As the Fund's sponsor and overall manager, Vanguard may provide investment advisory services to the Fund at any time. Vanguard may also recommend to the board of trustees that an advisor be hired, terminated, or replaced or that the terms of an existing advisory agreement be revised. The Fund has filed an application seeking a similar SEC exemption with respect to investment advisors that are wholly owned subsidiaries of Vanguard. If the exemption is granted, the Fund may rely on the new SEC relief.
For a discussion of why the board of trustees approved the Fund's investment advisory arrangement, see the most recent semiannual report to shareholders covering the fiscal period ended June 30.

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 short-term or long-term capital gains realized from the sale of its holdings. From time to time, the Fund may also make distributions that are treated as a return of capital. Income dividends generally are declared monthly and distributed monthly; capital gains distributions, if any, generally occur annually in December. In addition, the Fund may occasionally make a supplemental distribution at some other time during the year.
22

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.
Reinvestment of Distributions
In order to reinvest dividend and capital gains distributions, investors in the Fund must hold their shares at a broker that offers a reinvestment service. This can be the broker’s own service or a service made available by a third party, such as the broker’s outside clearing firm or the Depository Trust Company (DTC). If a reinvestment service is available, distributions of income and capital gains can automatically be reinvested in additional whole and fractional ETF Shares of the Fund. If a reinvestment service is not available, investors will receive their distributions in cash. To determine whether a reinvestment service is available and whether there is a commission or other charge for using this service, consult your broker.
As with all exchange-traded funds, reinvestment of dividend and capital gains distributions in additional ETF Shares will occur four business days or more after the ex-dividend date (the date when a distribution of dividends or capital gains is deducted from the price of the Fund’s shares). The exact number of days depends on your broker. During that time, the amount of your distribution will not be invested in the Fund and therefore will not share in the Fund’s income, gains, and losses.
Basic Tax Points
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 ETF Shares.
• Distributions declared in December—if paid to you by the end of January—are taxable as if received in December.
• Any income dividend distribution or short-term capital gains distribution that you receive is taxable to you as ordinary income.
23

• Any distribution of net long-term capital gains is taxable to you as long-term capital gains, no matter how long you have owned ETF Shares.
• Income and capital gains distributions may vary considerably from month to month or year to year, as applicable, as a result of the Fund's normal investment activities and cash flows.
• Your cost basis in the Fund will be decreased by the amount of any return of capital that you receive. This, in turn, will affect the amount of any capital gain or loss that you realize when selling your ETF Shares.
• Return of capital distributions generally are not taxable to you until your cost basis has been reduced to zero. If your cost basis is at zero, return of capital distributions will be treated as capital gains.
• A sale of ETF 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.
Individuals, trusts, and estates whose income exceeds certain threshold amounts are subject to a 3.8% Medicare contribution tax on “net investment income.” Net investment income takes into account distributions paid by the Fund and capital gains from any sale of ETF Shares.
Income dividends and capital gains distributions that you receive, as well as your gains or losses from any sale of ETF Shares, may be subject to state and local income taxes. Depending on your state’s rules, however, any dividends attributable to interest earned on direct obligations of the U.S. government may be exempt from state and local taxes. Vanguard will notify you each year how much, if any, of your dividends may qualify for this exemption.
This prospectus provides general tax information only. If you are investing through a tax-advantaged account, such as an IRA or an employer-sponsored retirement or savings plan, special tax rules apply. Please consult your tax advisor for detailed information about any tax consequences for you.
Share Price and Market Price
Share price, also known as net asset value (NAV), is calculated as of the close of regular trading on the New York Stock Exchange (NYSE), generally 4 p.m., Eastern time, on each day that the NYSE is open for business (a business day). In the rare event the NYSE experiences unanticipated disruptions and is unavailable at the close of the trading day, NAVs will be calculated as of the close of regular trading on the Nasdaq (or another alternate exchange if the Nasdaq is unavailable, as determined at Vanguard’s discretion), generally 4 p.m.,
24

Eastern time. The NAV per share is computed by dividing the total assets, minus liabilities, of the Fund by the number of Fund shares outstanding. On U.S. holidays or other days when the NYSE is closed, the NAV is not calculated, and the Fund does not sell or redeem shares. However, on those days the value of the Fund’s assets may be affected to the extent that the Fund holds securities that change in value on those days (such as foreign securities that trade on foreign markets that are open).
Remember: If you buy or sell ETF Shares on the secondary market, you will pay or receive the market price, which may be higher or lower than NAV. Your transaction will be priced at NAV only if you purchase or redeem your ETF Shares in Creation Unit blocks (an option available only to certain authorized broker-dealers).
Debt securities held by a Vanguard fund are valued based on information furnished by an independent pricing service or market quotations. 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).
The values of any foreign securities held by a fund are converted into U.S. dollars using an exchange rate obtained from an independent third party as of the close of regular trading on the NYSE. The values of any mutual fund shares, including institutional money market fund shares, held by a fund are based on the NAVs of the shares. The values of any ETF shares or closed-end fund shares held by a fund are based on the market value of the shares.
A fund also may use fair-value pricing on bond market holidays when the fund is open for business (such as Columbus Day and Veterans 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’s website will show the previous day’s closing NAV and closing market price for the Fund’s ETF Shares.

Additional Information
The Fund's Bylaws require, unless the Trust otherwise consents in writing, that the U.S. Federal District Courts be the sole and exclusive forum for the resolution of complaints under the Securities Act of 1933. This provision may limit a shareholder’s ability to bring a claim in a different forum and may result in increased shareholder costs in pursuing such a claim.

Financial Highlights
Financial highlights information is intended to help you understand a fund’s performance for the past five years (or, if shorter, its period of operations). Certain information reflects financial results for a single fund share. Total return represents the rate that an investor would have earned or lost each period on an investment in a fund or share class (assuming reinvestment of all distributions). This information has been obtained from the financial statements audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with fund financial statements, is included in a fund’s most recent annual report to shareholders. You may obtain a free copy of a fund’s latest annual or semiannual report, which is available upon request.

Glossary of Investment Terms
Authorized Participant. Institutional investors that are permitted to purchase Creation Units directly from, and redeem Creation Units directly with, the issuing fund. To be an Authorized Participant, an entity must be a participant in the Depository Trust Company and must enter into an agreement with the fund’s Distributor.
Average Maturity. The average length of time until bonds held by a fund reach maturity and are repaid. In general, the longer the average maturity, the more a fund's share price fluctuates in response to changes in market interest rates. In calculating average maturity, a fund uses a bond’s maturity or, if applicable, an earlier date on which the advisor believes it is likely that a maturity-shortening device (such as a call, put, refunding, prepayment, or redemption provision or an adjustable coupon rate) will cause the bond to be repaid.
Bid-Ask Spread. The difference between the highest price a buyer is willing to pay to purchase ETF Shares (bid) and the lowest price a seller is willing to accept for ETF Shares (ask) when buying or selling shares in the secondary market.
Bond. A debt security (IOU) issued by a corporation, a government, or a government agency in exchange for the money the bondholder lends 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 Distributions. Payments to fund shareholders of gains realized on securities that a fund has sold at a profit, minus any realized losses.
Cash Equivalent Investments. Cash deposits, short-term bank deposits, and money market instruments that include U.S. Treasury bills and notes, bank certificates of deposit (CDs), repurchase agreements, commercial paper, and banker’s acceptances.
Corporate Bond. An IOU issued by a business that wants to borrow money. As with other types of bonds, the issuer promises to repay the borrowed money by a specific date and generally to make interest payments in the meantime.
Coupon Rate. 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.
Creation Unit. A large block of a specified number of ETF Shares. Certain broker-dealers known as “Authorized Participants” may purchase and redeem ETF Shares from the issuing fund in Creation Unit size blocks.
29

Dividend Distributions. Payments to fund shareholders of income from interest or dividends generated by a fund's investments.
Ex-Dividend Date. The date when a distribution of dividends and/or capital gains is deducted from the share price of a mutual fund, ETF, or stock. On the ex-dividend date, the share price drops by the amount of the distribution per share (plus or minus any market activity).
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 it 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 may pay a fixed, variable, or floating rate of interest.
Inception Date. The date on which the assets of a fund 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.
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.
30

Joint Committed Credit Facility. The Fund may participate, along with other funds managed by Vanguard, in a committed credit facility provided by a syndicate of lenders pursuant to a credit agreement that may be renewed annually; each Vanguard fund is individually liable for its borrowings, if any, under the credit facility. The amount and terms of the committed credit facility are subject to approval by the Fund's board of trustees and renegotiation with the lender syndicate on an annual basis. New funds, such as the Vanguard Ultra-Short Bond ETF, will generally be added to the agreement during the annual renewal process.
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.
New York Stock Exchange (NYSE). A stock exchange based in New York City that is open for regular trading on business days, Monday through Friday, from 9:30 a.m. to 4 p.m., Eastern time.
Return of Capital. A return of capital occurs when a fund's distributions exceed its earnings in a fiscal year. A return of capital is a return of all or part of your original investment or amounts paid in excess of your original investment in a fund. In general, a return of capital reduces your cost basis in a fund's shares and is not taxable to you until your cost basis has been reduced to zero.
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 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.
