Fund Summary

Investment Objective

With 60% of its assets, the Fund seeks to track the performance of a benchmark index that measures the investment return of the overall U.S. stock market. With 40% of its assets, the Fund seeks to track the performance of a broad, market-weighted bond index.

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 certain fund account balances	$20/year	$20/year
below $10,000)

Annual Fund Operating Expenses
(Expenses that you pay each year as a percentage of the value of your investment)
	Investor Shares	Admiral Shares
Management Fees	0.21%	0.07%
12b-1 Distribution Fee	None	None
Other Expenses	0.03%	0.02%
Total Annual Fund Operating Expenses	0.24%	0.09%

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	5 Years	10 Years
Investor Shares	$25	$77	$135	$306
Admiral Shares	$9	$29	$51	$115

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 examples, reduce the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 47%.

Primary Investment Strategies

The Fund employs an indexing investment approach designed to track the performance of two benchmark indexes. The Fund invests by sampling its target indexes, meaning that it holds a range of securities that, in the aggregate, approximates the full indexes in terms of key characteristics.

With approximately 60% of its assets, the Fund seeks to track the investment performance of the CRSP US Total Market Index, which represents approximately 100% of the investable U.S. stock market and includes large-, mid-, small-, and micro-cap stocks regularly traded on the New York Stock Exchange and Nasdaq. The Fund samples the Index by holding a broadly diversified collection of stocks that, in the aggregate, approximates the full Index.

With approximately 40% of its assets, the Fund seeks to track the investment performance of the Barclays U.S. Aggregate Float Adjusted Index, which represents a wide spectrum of public, investment-grade, taxable, fixed income securities in the United States—including government, corporate, and international dollar-denominated bonds, as well as mortgage-backed and asset-backed securities, all with maturities of more than 1 year. At least 80% of the bond portion of the Fund is invested in bonds

held in the Barclays U.S. Aggregate Float Adjusted Index, and all of the Fund’s bond holdings are selected through the sampling process. The bond portion of the Fund maintains a dollar-weighted average maturity consistent with that of the Index, which ranges between 5 and 10 years.

Primary Risks

The Fund is subject to the risks associated with the stock and bond markets, any of which could cause an investor to lose money. However, because stock and bond prices can move in different directions or to different degrees, the Fund’s bond holdings may counteract some of the volatility experienced by the Fund’s stock holdings.

• With approximately 60% of its assets allocated to stocks, the Fund is proportionately subject to stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices. In addition, the Fund’s target index may, at times, become focused in stocks of a particular market sector, which would subject the Fund to proportionately higher exposure to the risks of that sector.

• With approximately 40% of its assets allocated to bonds, the Fund is proportionately subject to bond risks, including interest rate risk, which is the chance that bond prices overall will decline because of rising interest rates; income risk, which is the chance that the Fund’s income will decline because of falling interest rates; credit risk, which is the chance that a bond issuer will fail to pay interest and principal in a timely manner, or that negative perceptions of the issuer’s ability to make such payments will cause the price of that bond to decline; and call risk, which is the chance that during periods of falling interest rates, issuers of callable bonds may call (redeem) securities with higher coupons or interest rates before their maturity dates. The 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.

• The Fund is also subject to index sampling risk, which is the chance that the securities selected for the Fund will not provide investment performance matching that of the Fund’s target indexes.

An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Annual Total Returns

The following bar chart and table are intended to help you understand the risks of investing in the Fund. The bar chart shows how the performance of the Fund‘s Investor Shares has varied from one calendar year to another over the periods shown. The table shows how the average annual total returns of the share classes presented compare with those of relevant market indexes and other comparative indexes, which have investment characteristics similar to those of the Fund. Effective January 15, 2013, the Fund began tracking the CRSP US Total Market Index as its target stock index. The Fund‘s board of trustees believes that tracking the current index will result in considerable savings for the Fund‘s shareholders over time. Keep in mind that the Fund’s past performance (before and after taxes) does not indicate how the Fund will perform in the future. Updated performance information is available on our website at vanguard.com/performance or by calling Vanguard toll-free at 800-662-7447.

Annual Total Returns — Vanguard Balanced Index Fund Investor Shares

During the periods shown in the bar chart, the highest return for a calendar quarter was 11.26% (quarter ended September 30, 2009), and the lowest return for a quarter was –12.54% (quarter ended December 31, 2008).

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

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 a 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 they 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 and industries.

• 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 brokerage commissions, dealer markups, and other transaction costs—to a minimum.

More on the Fund

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 Signal^®Shares, which are generally for institutional and financial intermediary investors. Another prospectus offers the Fund’s Institutional Shares, which are generally for investors who invest a minimum of $5 million.

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 Balanced Index Fund’s expense ratios would be as

follows: for Investor Shares, 0.24%, or $2.40 per $1,000 of average net assets;

for Admiral Shares, 0.09%, or $0.90 per $1,000 of average net assets. The

average expense ratio for mixed-asset target allocation growth funds in 2013 was

1.35%, or $13.50 per $1,000 of average net assets (derived from data provided by

Lipper, a Thomson Reuters Company, which reports on the mutual fund industry).

Plain Talk About Costs of Investing

Costs are an important consideration in choosing a mutual fund. That is 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. Note that the Fund’s investment objective is not fundamental and may be changed without a shareholder vote.

Plain Talk About Balanced Funds

Balanced funds are generally investments that seek to provide some combination

of income and capital appreciation by investing in a mix of stocks and bonds.

Because prices of stocks and bonds can respond differently to economic events

and influences, a balanced fund should experience less volatility than a fund

investing exclusively in stocks.

Market Exposure

Stocks

Approximately 60% of the Fund’s assets are invested in stocks.

The Fund is subject to stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices. In addition, the Fund’s target index may, at times, become focused in stocks of a particular market sector, which would subject the Fund to proportionately higher exposure to the risks of that sector.

Note that the returns shown do not include the costs of buying and selling stocks or other expenses that a real-world investment portfolio would incur.


U.S. Stock Market Returns
(1926–2013)
	1 Year	5 Years	10 Years	20 Years
Best	54.2%	28.6%	19.9%	17.8%
Worst	–43.1	–12.4	–1.4	3.1
Average	12.0	9.9	10.4	11.1

The table covers all of the 1-, 5-, 10-, and 20-year periods from 1926 through 2013. You can see, for example, that although the average annual return on common stocks for all of the 5-year periods was 9.9%, average annual returns for individual 5-year periods ranged from –12.4% (from 1928 through 1932) to 28.6% (from 1995 through 1999). These average annual returns reflect past performance of common stocks; you should not regard them as an indication of future performance of either the stock market as a whole or the Fund in particular.

Although the Fund will include a broadly diversified collection of stocks in the CRSP US Total Market Index, it will not include all of the securities in the Index. Instead, the Fund will invest in a representative sample of stocks.

Stocks of publicly traded companies and funds that invest in stocks are often classified according to market value, or market capitalization. These classifications typically include small-cap, mid-cap, and large-cap. It is important to understand that, for both companies and stock funds, market-capitalization ranges change over time. Also, interpretations of size vary, and there are no “official” definitions of small-, mid-, and large-cap, even among Vanguard fund advisors. The asset-weighted median market capitalization of the Fund’s stock holdings as of December 31, 2013, was $45.7 billion.

Although the CRSP US Total Market Index is dominated by large-cap stocks (those tracked by the S&P 500 Index), mid-, small-, and micro-cap stocks are also represented. As of December 31, 2013, approximately 24% of the market value of the CRSP US Total Market Index was made up of securities that were not in the S&P 500 Index. Historically, mid-, small-, and micro-cap stocks have been more volatile than—and at times have performed quite differently from—large-cap stocks.

Bonds

Approximately 40% of the Fund’s assets are invested in bonds.

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 because the average term of the Fund’s bond portfolio is generally intermediate-term and because the Fund’s bond holdings represent less than half of the Fund’s assets.

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 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 (i.e., they cannot be redeemed by the issuer) bonds of different maturities, each with a face value of $1,000.


How Interest Rate Changes Affect the Value of a $1,000 Bond¹
	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 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.

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 holding bonds will experience a decline in income when interest rates fall because the fund then must invest new cash flow and cash from maturing bonds in lower-yielding bonds.

Although income risk for short- and intermediate-term bonds—like those held by the Fund—is considered moderate, this risk should be low for the Fund because it invests only a portion of its assets in 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.

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.

The credit quality of the Fund is expected to be very high, and thus credit risk should be low.

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

Investors Service, Inc., 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 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 portion of its assets in callable bonds and mortgage-backed securities, call/prepayment risk for the Fund should be low.

To a limited extent, the Fund is also exposed 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 corporate restructuring or another corporate event.

The Fund’s bond holdings help to reduce—but not eliminate—some of the stock market volatility that may be experienced by the Fund. Likewise, changes in interest rates may not have as dramatic an effect on the Fund as they would on a fund made up entirely of bonds. The Fund’s balanced portfolio, in the long run, should result in less investment risk—and a lower investment return—than a fund investing exclusively in common stocks.

Security Selection

Index sampling strategy. Because it would be very expensive and inefficient to buy and sell all the securities held in its target indexes, the Fund uses an index “sampling” technique to select securities. Using computer programs, the Fund generally selects a representative sample of securities that approximates the full target indexes in terms of key characteristics. In its stock portion, the Fund holds a broadly diversified collection of the stocks in the CRSP US Total Market Index and a representative sample of the remaining stocks. In its bond portion, the Fund considers factors such as duration, cash flow, quality, and callability of the underlying bonds when sampling the Barclays U.S. Aggregate Float Adjusted Index. In addition, the Fund keeps industry sector and subsector exposure for bonds within tight boundaries compared with that of the Index.

Because the Fund does not hold all the securities in its target indexes, some of the securities (and issuers) that are held will likely be overweighted compared with the target indexes.

The Fund is subject to index sampling risk, which is the chance that the securities selected for the Fund will not provide investment performance matching that of the Fund’s target indexes.

Types of bonds. The Fund’s target index for bonds, the Barclays U.S. Aggregate Float Adjusted Index, represents a wide spectrum of investment-grade fixed income securities in the United States—including government, corporate, and international dollar-denominated bonds, as well as mortgage-backed and asset-backed securities, all with maturities of more than 1 year.

As of December 31, 2013, the Fund’s bond portion was made up of the following types of bonds:


			International
U.S.		Mortgage-	Dollar-
Government	Corporate	Backed	Denominated	Other	Total

45.2%	26.4%	22.2%	5.3%	0.9%	100%

An explanation of each type of bond 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. Timely payment of principal and interest on U.S. Treasury bonds is always guaranteed by the full faith and credit of the U.S. government; many (but not all) agency bonds have the same guarantee. The market values of U.S. government and agency securities and U.S. Treasury securities are subject to fluctuation.

• Corporate bonds are IOUs issued by businesses that want to borrow money for some purpose—often to develop a new product or service, to expand into a new market, or to buy another company. As with other types of bonds, the issuer promises to repay the principal on a specific date and to make interest payments in the meantime. The amount of interest offered depends both on market conditions and on the financial health of the corporation issuing the bonds; a company whose credit rating is not strong will have to offer a higher interest rate to obtain buyers for its bonds. Corporate bonds include securities that are backed by a pool of underlying assets (asset-backed securities) or commercial mortgages (commercial mortgage-backed bonds). The Fund expects to purchase only investment-grade corporate bonds.

• Mortgage-backed securities represent interests in underlying pools of mortgages.

Unlike ordinary bonds, which generally pay a fixed rate of interest at regular intervals and then repay principal upon maturity, mortgage-backed securities pass through both interest and principal from underlying mortgages as part of their regular payments. Because the mortgages underlying the securities can be prepaid at any time by homeowners or corporate borrowers, mortgage-backed securities are subject to prepayment risk. These types of securities are issued by a number of government agencies, including the Government National Mortgage Association (GNMA), the Federal Home Loan Mortgage Corporation (FHLMC), and the Federal National Mortgage Association (FNMA). GNMAs are guaranteed by the full faith and credit of the U.S. government as to the timely payment of principal and interest; mortgage-backed securities issued by other government agencies or private corporations are not.

purchase similar securities in the future at a predetermined price. These transactions simulate an investment in mortgage-backed securities and have the potential to enhance the Fund’s returns and reduce its administrative burdens, compared with holding mortgage-backed securities directly. These transactions may increase a fund’s portfolio turnover rate. Mortgage dollar rolls will be used only if consistent with the Fund’s investment objective and risk profile.

• International dollar-denominated bonds are bonds denominated in U.S. dollars and issued by foreign governments and companies. To the extent that it owns foreign bonds, the Fund 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 of securities issued by companies in foreign countries. 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 the risk, usually to attract U.S. investors.

Other Investment Policies and Risks

The Fund reserves the right to substitute a different index for either of the indexes that it currently tracks if a current index is discontinued, if the Fund’s agreement with the sponsor of a current 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 market segment as the current index.

The Fund may invest in foreign stocks to the extent necessary to carry out its investment strategy of holding a representative sample of the stocks that make up the index it tracks. It is not expected that the Fund will invest more than 5% of its assets in foreign stocks.

Up to 20% of the bond portion of the Fund may be used to purchase nonpublic, investment-grade securities, generally referred to as 144A securities, as well as smaller public issues or medium-term notes not included in the Barclays U.S. Aggregate Float Adjusted Index because of the size of the issue. Subject to the same 20% limit, the Fund also may invest in relatively conservative classes of collateralized mortgage obligations (CMOs), which offer a high degree of cash-flow predictability and a low level of vulnerability to mortgage prepayment risk. To reduce credit risk, these CMOs are purchased only if issued by agencies of the U.S. government or by private companies that carry high-quality investment-grade ratings. The vast majority of any such securities will have characteristics and risks similar to those in the Index.

greater than, those of investments directly in the underlying securities, assets, or market indexes. The Fund will not use derivatives for speculation or for the purpose of leveraging (magnifying) investment returns.

The Fund may purchase money market instruments and certain derivatives in order to manage cash flow into and out of the Fund, reduce the Fund’s transaction costs, or add value when these instruments are favorably priced.

Vanguard may invest a small portion of the Fund’s assets in stock futures and U.S. Treasury futures, which are types of derivatives, and/or shares of stock and bond exchange-traded funds (ETFs). These futures and ETFs typically provide returns similar to those of the stocks and bonds listed in the index, or in a subset of the index, tracked by the Fund. Vanguard may purchase futures or 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

Background. Some investors try to profit from strategies involving frequent trading of mutual fund shares, such as market-timing. For funds holding foreign securities, investors may try to take advantage of an anticipated difference between the price of the fund’s shares and price movements in overseas markets, a practice also known as time-zone arbitrage. Investors also may try to engage in frequent trading of funds 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, but including Vanguard Short-Term Inflation-Protected Securities Index Fund) do not knowingly accommodate frequent trading. The board of trustees of each Vanguard fund (other than money market funds and short-term bond funds, but including Vanguard Short-Term Inflation-Protected Securities Index Fund) 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 the investor has a history of frequent trading 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, but including Vanguard Short-Term Inflation-Protected Securities Index Fund) 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 Vanguard fund (other than money market funds), in determining its net asset value, will use fair-value pricing when appropriate, 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, it may sell securities regardless of how long they have been held. Generally, an index fund sells securities in response to redemption requests or to changes in the composition of its target index, or in an effort to manage the fund’s duration. 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. The Financial Highlights section of this prospectus shows historical turnover rates for the Fund. Portfolio adjustments in response to larger index rebalancing by the Fund’s former index provider during the fiscal year ended December 31, 2011, resulted in an increase in turnover rate for that year. The average turnover rate for balanced funds was approximately 64%, as reported by Morningstar, Inc., on December 31, 2013.

Plain Talk About Turnover Rate

Before investing in a mutual fund, you should review its turnover rate. This 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 brokerage

commissions, 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 170 mutual funds holding assets of approximately $2.4 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 Equity Investment and Fixed Income Groups. As of December 31, 2013, Vanguard served as advisor for approximately $2.1 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 the fiscal year ended December 31, 2013, the advisory expenses represented an effective annual rate of 0.01% of the Fund’s average net assets.

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 and dividends, less expenses) as well as any net capital gains realized from the sale of its holdings. Income dividends generally are distributed quarterly in March, June, September, and December; 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. 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

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

consists of both the dividends that the fund earns from any stock holdings and the

interest it receives from any 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. If you are an individual and meet certain holding-period requirements with respect to your Fund shares, you may be eligible for reduced tax rates on “qualified dividend income,”if any, distributed by the Fund.

• Any distributions of net long-term capital gains are taxable to you as long-term capital gains, no matter how long you have 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 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 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.

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.

Plain Talk About Buying a Dividend

Unless you are investing through a tax-deferred retirement account (such as an

IRA), you should consider avoiding a purchase of fund shares shortly before the

fund makes a distribution, because doing so can cost you money in taxes. This is

known as “buying a dividend.” For example: On December 15, you invest $5,000,

buying 250 shares for $20 each. If the fund pays a distribution of $1 per share on

December 16, its share price will drop to $19 (not counting market change). You

still have only $5,000 (250 shares x $19 = $4,750 in share value, plus 250 shares

x $1 = $250 in distributions), but you owe tax on the $250 distribution you

received—even if you reinvest it in more shares. To avoid buying a dividend, check

a fund’s distribution schedule before you invest.

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.

• 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.

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 U.S. holidays or other days when the Exchange 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 foreign securities that trade on foreign markets that are open.

Stocks held by a Vanguard fund are valued at their market value when reliable market quotations are readily available. Debt securities held by a 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 foreign securities held by a fund are converted into U.S. dollars using an exchange rate obtained from an independent third party. 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.

time. Intervening events might be company-specific (e.g., earnings report, merger announcement) 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. Fair-value pricing may be used for domestic securities—for example, if (1) trading in a security is halted and does not resume before the fund’s pricing time or a security does not trade in the course of a day and (2) the fund holds enough of the security that its price could affect the NAV. A fund may use fair-value pricing with respect to its fixed income securities 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 fund share prices are published daily on our website at vanguard.com/prices.

Financial Highlights

The following financial highlights tables are intended to help you understand the Fund’s financial performance for the periods shown, and certain information reflects financial results for a single Fund share. The total returns in each table represent the rate that an investor would have earned or lost each period on an investment in the Fund (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 the Fund’s financial statements—is included in the Fund‘s most recent annual report to shareholders. You may obtain a free copy of the latest annual or semiannual report by visiting vanguard.com or by contacting Vanguard by telephone or mail.

Plain Talk About How to Read the Financial Highlights Tables

This explanation uses the Fund’s Investor Shares as an example. The Investor

Shares began fiscal year 2013 with a net asset value (share price) of $23.76 per

share. During the year, each Investor Share earned $0.473 from investment

income (interest and dividends) and $3.754 from investments that had

appreciated in value or that were sold for higher prices than the Fund paid

for them.

Shareholders received $0.467 per share in the form of dividend distributions. A

portion of each year’s distributions may come from the prior year’s income or

capital gains.

The share price at the end of the year was $27.52, reflecting earnings of $4.227

per share and distributions of $0.467 per share. This was an increase of $3.76 per

share (from $23.76 at the beginning of the year to $27.52 at the end of the year).

For a shareholder who reinvested the distributions in the purchase of more

shares, the total return was 17.91% for the year.

As of December 31, 2013, the Investor Shares had approximately $3 billion in net

assets. For the year, the expense ratio was 0.24% ($2.40 per $1,000 of net

assets), and the net investment income amounted to 1.84% of average net

assets. The Fund sold and replaced securities valued at 47% of its net assets.

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.

To 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 and financial intermediary clients should contact Vanguard for information on special eligibility rules that may apply to them.

To 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 service 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 service is set up on your account, you can purchase shares by electronic bank transfer on a regular schedule (Automatic Investment Plan) or upon request. 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 by utilizing 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 the date you designated for withdrawal of funds from your bank account. Your bank account generally will be debited on the business day after your trade date. If the date you designated for withdrawal of funds from your bank account falls on a weekend, holiday, or other nonbusiness day, your trade date generally will be the previous business day.

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

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. Certain types of accounts may require additional documentation.

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 the investor has a history of frequent trading 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.

Vanguard will not accept your request to cancel any self-directed conversion request once processing has begun. Please be careful when placing a conversion request.

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).

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.

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 and financial intermediary 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 and financial intermediary 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 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.

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 service 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 service is set up on your account, you can redeem shares by electronic bank transfer on a regular schedule (Automatic Withdrawal Plan) or upon request. 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 service, 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.

Share certificates. Share certificates are no longer issued for Vanguard funds. Shares currently held in certificates cannot be redeemed, exchanged, converted, or transferred (reregistered) until you return the certificates (unsigned) to Vanguard by registered mail. For the correct address, see Contacting Vanguard.

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.

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, but including Vanguard Short-Term Inflation-Protected Securities Index Fund) 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.

Investing With Vanguard Through Other Firms

You may purchase or sell shares of most Vanguard funds through a financial intermediary, such as a bank, a broker, or an investment advisor. Please consult your financial intermediary to determine which, if any, shares are available through that firm and to learn about other rules that may apply.

Please see Frequent-Trading Limitations—Accounts Held by Intermediaries for information about the assessment of any purchase or redemption fees and the monitoring of frequent trading for accounts held by intermediaries.

Account Service Fee

Vanguard charges a $20 account service fee on fund accounts that have a balance below $10,000 for any reason, including market fluctuation. 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 the account minimum. 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 institutional clients.
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.

The Fund reserves the right to liquidate a fund account whose balance falls below the account minimum 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.

Fund and Account Updates

Confirmation Statements

We will send (or provide through our website, whichever you prefer) a confirmation of your trade date and the amount of your transaction when you buy, sell, exchange, or convert shares. However, we will not send confirmations reflecting only checkwriting redemptions or the reinvestment of dividend or capital gains distributions. For any month in which you had a checkwriting redemption, a Checkwriting Activity Statement will be sent to you itemizing the checkwriting redemptions for that month. Promptly review each confirmation statement that we provide to you. It is important that you contact Vanguard immediately with any questions you may have about any

transaction reflected on a confirmation statement, or Vanguard will consider the transaction properly processed.

If you prefer, you may request to receive monthly portfolio summaries. Each summary shows the market value of your account at the close of the statement period, as well as all distributions, purchases, redemptions, exchanges, transfers, and conversions for the current calendar quarter (or month). Promptly review each summary that we provide to you. It is important that you contact Vanguard immediately with any questions you may have about any transaction reflected on the summary, or Vanguard will consider the transaction properly processed.

Tax Information Statements

For most accounts, we are required to provide annual tax forms to assist you in preparing your income tax returns. We will generally send (or provide through our website, whichever you prefer) annual tax forms in January. These forms will report the previous year’s dividends, capital gains distributions, proceeds from the sale of shares from taxable accounts, and distributions from IRAs and other retirement plans. Registered users of vanguard.com can also view these forms through our website. Vanguard may also provide you with additional tax-related documentation. For more information, consult our website at vanguard.com or see Contacting Vanguard.

Financial statements with listings of Fund holdings.

Portfolio Holdings

We generally post on our website at vanguard.com, in the Portfolio section of the Fund’s Portfolio & Management page, a detailed list of the securities held by the Fund as of the end of the most recent month. This list is generally updated 15 calendar days after the end of the month. Vanguard may exclude any portion of these portfolio holdings from publication when deemed in the best interest of the Fund. We also generally post the ten largest stock portfolio holdings of the Fund and the percentage of the Fund’s total assets that each of these holdings represents, as of the end of the most recent month. This list is generally updated 15 calendar days after the end of the month.

Glossary of Investment Terms

Active Management. An investment approach that seeks to exceed the average returns of a particular financial market or market segment. In selecting securities to buy and sell, active managers may rely on, among other things, research, market forecasts, quantitative models, and their own judgment and experience.

Balanced Composite Index. An index that is weighted 60% Dow Jones U.S. Total Stock Market Index (formerly known as the Dow Jones Wilshire 5000 Index) and 40% Lehman Brothers U.S. Aggregate Bond Index through May 31, 2005; 60% MSCI US Broad Market Index and 40% Barclays U.S. Aggregate Bond Index through December 31, 2009; 60% MSCI US Broad Market Index and 40%Barclays U.S. Aggregate Float Adjusted Index through January 14, 2013; and 60% CRSP US Total Market Index and 40% Barclays U.S. Aggregate Float Adjusted Index thereafter.

Bond. A debt security (IOU) issued by a corporation, a government, or a 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.

Common Stock. A security representing ownership rights in a corporation. A stockholder is entitled to share in the company’s profits, some of which may be paid out as dividends.

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.

Duration. A measure of the sensitivity of bond—and bond fund—prices to interest rate movements. For example, if a bond has a duration of two years, its price would fall by approximately 2% when interest rates rose by 1%. On the other hand, the bond’s price would rise by approximately 2% when interest rates fell by 1%.

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 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.

Median Market Capitalization. An indicator of the size of companies in which a fund invests; the midpoint of market capitalization (market price x shares outstanding) of a fund’s stocks, weighted by the proportion of the fund’s assets invested in each stock. Stocks representing half of the fund’s assets have market capitalizations above the median, and the rest are below it.

MSCI US Broad Market Index. An index that tracks virtually all stocks that trade in the U.S. stock market.

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.

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

Spliced Barclays U.S. Aggregate Float Adjusted Index. An index that reflects performance of the Barclays U.S. Aggregate Bond Index (not float-adjusted) through December 31, 2009, and performance of the Barclays U.S. Aggregate Float Adjusted Index thereafter.

Spliced Total Stock Market Index. An index that reflects performance of the Dow Jones U.S. Total Stock Market Index (formerly known as the Dow Jones Wilshire 5000 Index) through April 22, 2005; the MSCI US Broad Market Index through June 2, 2013; and the CRSP US Total Market Index thereafter.

Fund Summary

Investment Objective

Fees and Expenses

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


Shareholder Fees
(Fees paid directly from your investment)

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

Example

The following example is intended to help you compare the cost of investing in the Fund’s Investor Shares with the cost of investing in other mutual funds. It illustrates the hypothetical expenses that you would incur over various periods if you invest $10,000 in the Fund’s shares. This example assumes that the Shares provide a return of 5% a year and that 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	5 Years	10 Years
$25	$77	$135	$306

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in more taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense example, reduce the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 47%.

Primary Investment Strategies

holdings are selected through the sampling process. The bond portion of the Fund maintains a dollar-weighted average maturity consistent with that of the Index, which ranges between 5 and 10 years.

Primary Risks

An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Annual Total Returns

The following bar chart and table are intended to help you understand the risks of investing in the Fund. The bar chart shows how the performance of the Fund‘s Investor Shares has varied from one calendar year to another over the periods shown. The table shows how the average annual total returns of the Investor Shares compare with those of relevant market indexes and other comparative indexes, which have investment characteristics similar to those of the Fund. Effective January 15, 2013, the Fund began tracking the CRSP US Total Market Index as its target stock index. The Fund‘s board of trustees believes that tracking the current index will result in considerable savings for the Fund‘s shareholders over time. Keep in mind that the Fund’s past performance does not indicate how the Fund will perform in the future. Updated performance information is available on our website at vanguard.com/ performance or by calling Vanguard toll-free at 800-662-7447.

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 and industries.

• 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 brokerage commissions, dealer markups, and other transaction costs—to a minimum.

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 Balanced Index Fund Investor Shares’ expense ratio

would be 0.24%, or $2.40 per $1,000 of average net assets. The average

expense ratio for mixed-asset target allocation growth funds in 2013 was 1.35%,

or $13.50 per $1,000 of average net assets (derived from data provided by Lipper,

a Thomson Reuters Company, which reports on the mutual fund industry).

Plain Talk About Costs of Investing

Costs are an important consideration in choosing a mutual fund. That is 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.

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.

Plain Talk About Balanced Funds

Balanced funds are generally investments that seek to provide some combination

of income and capital appreciation by investing in a mix of stocks and bonds.

Because prices of stocks and bonds can respond differently to economic events

and influences, a balanced fund should experience less volatility than a fund

investing exclusively in stocks.

Market Exposure

Stocks

Approximately 60% of the Fund’s assets are invested in stocks.

To illustrate the volatility of stock prices, the following table shows the best, worst, and average annual total returns for the U.S. stock market over various periods as measured by the Standard & Poor‘s 500 Index, a widely used barometer of U.S. market activity. (Total returns consist of dividend income plus change in market price.) Note that the returns shown do not include the costs of buying and selling stocks or other expenses that a real-world investment portfolio would incur.

Best	54.2%	28.6%	19.9%	17.8%
Worst	–43.1	–12.4	–1.4	3.1
Average	12.0	9.9	10.4	11.1

Bonds

Approximately 40% of the Fund’s assets are invested in bonds.
