CHAIRMAN’S LETTER

Dear Shareholder,

During the six months ended June 30, 2005, Vanguard Institutional Index Fund returned –0.8% as U.S. stocks modestly drifted backward and then forward. This return matched the –0.8% return of the fund’s benchmark, the Standard & Poor’s 500 Index, and was slightly better than the –1.2% average return of the fund’s peer group.

STOCKS MADE LITTLE HEADWAY

Following a formidable rally to close out 2004, the broad U.S. market at different times stumbled and recovered during the first half of 2005, but the net effect was a flat finish for the broad market, as measured by the Dow Jones Wilshire 5000 Composite Index.

Investors were cheered as home-buying activity remained high by historical standards, knowing that new homeowners fuel the economy by buying appliances and other home furnishings. But the market also faced headwinds: rising short-term interest rates and gas prices (which can curtail consumer spending), and mounting trade and budget deficits. Some analysts wondered whether the home-buying spree was a problem, given signs that some buyers are speculating on real estate.

Value stocks—those with prices below average, given the companies’ book value and other criteria—prolonged their five-year roll of

1

outperforming growth stocks, which dominated the market in the late 1990s. In a reversal of recent trends, returns for large-capitalization stocks topped those of the market’s smaller companies. International stocks outperformed their U.S. counterparts; however, a strengthening dollar wiped out most of that edge for U.S. investors. The dollar rallied as the gap between short-term interest rates in the States and in Europe widened.

THE BOND MARKET’S DICHOTOMY PERSISTED

The Lehman Brothers Aggregate Bond Index, which reflects the taxable investment-grade bond market, posted a 2.5% return during the six months. U.S. government and municipal issues performed best, while corporate securities matched the index return and mortgage-backed debt trailed.

The Federal Reserve Board raised the target federal funds rate in four equal steps, leaving it at 3.25% at the end of the period. The yield of the 3-month U.S. Treasury bill moved in sync, closing the period at 3.12%. Long-term rates didn’t follow, as prices were propped up by demand for the securities from foreign buyers and pension funds. The yield of the 10-year Treasury note finished the period at 3.91%, a drop of 31 basis points (0.31 percentage point) over the six months. The yield of the 30-year Treasury bond fell 64 basis points to 4.19%.

THE FUND DRIFTED WITHIN A NARROW RANGE

Echoing the relatively quiet trading pattern that the U.S. stock market exhibited during the first half of 2005, Vanguard Institutional Index Fund closely tracked the S&P 500 Index with a –2.1% return during the first quarter, as investors grew cautious. There was a modest turnaround in market sentiment in the second quarter, and the fund advanced nearly 1.4%. The net result was a –0.8% decline for the six-month period.

2

As energy supplies continued to be tight and prices remained high, bullish sentiment continued to dominate trading among energy-related stocks. The “other energy” sector (+26.0%), which includes firms engaged in oil and natural gas exploration, production, and related products and services, recorded the highest gain. Integrated oils (+17.0%) had an even bigger impact on the fund’s returns because of the larger collective market value of big oil companies such as ExxonMobil, ConocoPhillips, and Chevron. Other advancing sectors included health care (+3.5%) and utilities (+3.8%).

*Fund expense ratios reflect the six months ended June 30, 2005. Peer-group expense ratio is derived from data provided by Lipper Inc. and captures information through year-end 2004.

Despite these advances, your fund’s performance, like that of the S&P 500 Index, was hurt by retreats in most sectors. Concerns about the sustainability of strong consumer spending in the face of rising short-term interest rates and energy prices weighed down the retailers, media, and entertainment companies that make up the consumer discretionary sector (–5.9%). Meanwhile, technology companies (–5.2%) declined as corporate IT spending continued to disappoint. Interest rate trends helped to slow financial services stocks (–2.1%), the index’s largest sector. And the auto & transportation sector (–15.7%) continued to struggle with fierce competition and formidable health care and pension liabilities.

FOCUSING ON LONG-TERM SUCCESS

The markets and the news media tend to focus on what to do now. As we never get tired of reminding our clients, successful long-term investing doesn’t mean paying attention to yesterday’s performance, today’s news, or analysts’ predictions for tomorrow. Instead, reaching your organization’s long-term goals requires a more patient approach—an approach that Vanguard Institutional Index Fund is ideally suited to support.

Whether the stock market rises or falls sharply or, as in the past six months, meanders sideways, an investment in Vanguard Institutional Index Fund gives you broad exposure to the market’s larger companies and positions your organization to benefit from the U.S. economy’s long-term growth potential.

3

In fact, the fund’s diversified nature, low turnover rate, and low costs represent a proven formula for managing all your investments. Long-term success is much more likely with a steady, diversified mix of low-cost stock, bond, and short-term investments tailored to your organization’s situation and goals. Thank you for your confidence in Vanguard. We look forward to reporting to you at the conclusion of 2005.

Sincerely,

John J. Brennan

CHAIRMAN AND CHIEF EXECUTIVE OFFICER

GLOSSARY OF INVESTMENT TERMS

Beta. A measure of the magnitude of a fund’s past share-price fluctuations in relation to the ups and downs of a given market index. The index is assigned a beta of 1.00. Compared with a given index, a fund with a beta of 1.20 typically would have seen its share price rise or fall by 12% when the index rose or fell by 10%. A fund’s beta should be reviewed in conjunction with its R-squared (see definition below). The lower the R-squared, the less correlation there is between the fund and the index, and the less reliable beta is as an indicator of volatility.

Earnings Growth Rate. The average annual rate of growth in earnings over the past five years for the stocks now in a fund.

Expense Ratio. The percentage of a fund’s average net assets used to pay its annual administrative and advisory expenses. These expenses directly reduce returns to investors.

Foreign Holdings. The percentage of a fund’s equity assets represented by stocks or depositary receipts of companies based outside the United States.

Median Market Cap. 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.

Price/Book Ratio. The share price of a stock divided by its net worth, or book value, per share. For a fund, the weighted average price/book ratio of the stocks it holds.

Price/Earnings Ratio. The ratio of a stock’s current price to its per-share earnings over the past year. For a fund, the weighted average P/E of the stocks it holds. P/E is an indicator of market expectations about corporate prospects; the higher the P/E, the greater the expectations for a company’s future growth.

R-Squared. A measure of how much of a fund’s past returns can be explained by the returns from the market in general, as measured by a given index. If a fund’s total returns were precisely synchronized with an index’s returns, its R-squared would be 1.00. If the fund’s returns bore no relationship to the index’s returns, its R-squared would be 0.

Return on Equity. The annual average rate of return generated by a company during the past five years for each dollar of shareholder’s equity (net income divided by shareholder’s equity). For a fund, the weighted average return on equity for the companies whose stocks it holds.

Short-Term Reserves. The percentage of a fund invested in highly liquid, short-term securities that can be readily converted to cash.

Turnover Rate. An indication of the fund’s trading activity. Funds with high turnover rates incur higher transaction costs and may be more likely to distribute capital gains (which may be taxable to investors). The turnover rate excludes in-kind transactions, which have minimal impact on costs.

Yield. A snapshot of a fund’s income from interest and dividends. The yield, expressed as a percentage of the fund’s net asset value, is based on income earned over the past 30 days and is annualized, or projected forward for the coming year. The index yield is based on the current annualized rate of income provided by securities in the index.

As of 6/30/2005 PERFORMANCE SUMMARY

All of the returns in this report represent past performance, which is not a guarantee of future results that may be achieved by the fund. (For performance data current to the most recent month-end, which may be higher or lower than that cited, visit our website at www.vanguard.com.) Note, too, that both investment returns and principal value can fluctuate widely, so an investor's shares, when sold, could be worth more or less than their original cost. The returns shown do not reflect taxes that a shareholder would pay on fund distributions or on the sale of fund shares.

As of 6/30/2005 FINANCIAL STATEMENTS (UNAUDITED)

STATEMENT OF NET ASSETS

This Statement provides a detailed list of the fund’s holdings, including each security’s market value on the last day of the reporting period. Securities are grouped and subtotaled by asset type (common stocks, bonds, etc.) and by industry sector. Other assets are added to, and liabilities are subtracted from, the value of Total Investments to calculate the fund’s Net Assets. Finally, Net Assets are divided by the outstanding shares of the fund to arrive at its share price, or Net Asset Value (NAV) Per Share.

At the end of the Statement of Net Assets, you will find a table displaying the composition of the fund’s net assets. Because all income and any realized gains must be distributed to shareholders each year, the bulk of net assets consists of Paid-in Capital (money invested by shareholders). The amounts shown for Undistributed Net Investment Income and Accumulated Net Realized Gains usually approximate the sums the fund had available to distribute to shareholders as income dividends or capital gains as of the statement date, but may differ because certain investments or transactions may be treated differently for financial statement and tax purposes. Any Accumulated Net Realized Losses, and any cumulative excess of distributions over net income or net realized gains, will appear as negative balances. Unrealized Appreciation (Depreciation) is the difference between the market value of the fund’s investments and their cost, and reflects the gains (losses) that would be realized if the fund were to sell all of its investments at their statement-date values.

The fund provides a complete list of its holdings four times in each fiscal year, at the quarter-ends. For the second and fourth fiscal quarters, the lists appear in the fund’s semiannual and annual reports to shareholders. For the first and third fiscal quarters, the fund files the lists with the Securities and Exchange Commission on Form N-Q. Shareholders can look up the fund’s Forms N-Q on the SEC’s website at www.sec.gov. Forms N-Q may also be reviewed and copied at the SEC’s Public Reference Room (see the back cover of this report for further information).

STATEMENT OF CHANGES IN NET ASSETS

This Statement shows how the fund’s total net assets changed during the two most recent reporting periods. The Operations section summarizes information detailed in the Statement of Operations. The amounts shown as Distributions to shareholders from the fund’s net income and capital gains may not match the amounts shown in the Operations section, because distributions are determined on a tax basis and may be made in a period different from the one in which the income was earned or the gains were realized on the financial statements. The Capital Share Transactions section shows the net amount shareholders invested in or redeemed from the fund. Distributions and Capital Share Transactions are shown separately for each class of shares.

FINANCIAL HIGHLIGHTS

This table summarizes the fund’s investment results and distributions to shareholders on a per-share basis for each class of shares. It also presents the Total Return and shows net investment income and expenses as percentages of average net assets. These data will help you assess: the variability of the fund’s net income and total returns from year to year; the relative contributions of net income and capital gains to the fund’s total return; how much it costs to operate the fund; and the extent to which the fund tends to distribute capital gains. The table also shows the Portfolio Turnover Rate, a measure of trading activity. A turnover rate of 100% means that the average security is held in the fund for one year.

NOTES TO FINANCIAL STATEMENTS

Vanguard Institutional Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares, Institutional Shares and Institutional Plus Shares, to investors who invest minimum amounts of $5 million and $200 million, respectively.

A. The following significant accounting policies conform to generally accepted accounting principles for U.S. mutual funds. The fund consistently follows such policies in preparing its financial statements.

1. Security Valuation: Securities are valued as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date. Equity securities are valued at the latest quoted sales prices or official closing prices taken from the primary market in which each security trades; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Securities for which market quotations are not readily available, or whose values have been materially affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued by methods deemed by the board of trustees to represent fair value. Investments in Vanguard Market Liquidity Fund are valued at that fund’s net asset value. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value.

2. Futures Contracts: The fund uses index futures contracts to a limited extent, with the objectives of maintaining full exposure to the stock market, enhancing returns, maintaining liquidity, and minimizing transaction costs. The fund may purchase futures contracts to immediately invest incoming cash in the market, or sell futures in response to cash outflows, thereby simulating a fully invested position in the underlying index while maintaining a cash balance for liquidity. The fund may seek to enhance returns by using futures contracts instead of the underlying securities when futures are believed to be priced more attractively than the underlying securities. The primary risks associated with the use of futures contracts are imperfect correlation between changes in market values of stocks held by the fund and the prices of futures contracts, and the possibility of an illiquid market.

Futures contracts are valued at their quoted daily settlement prices. The aggregate principal amounts of the contracts are not recorded in the financial statements. Fluctuations in the value of the contracts are recorded in the Statement of Net Assets as an asset (liability) and in the Statement of Operations as unrealized appreciation (depreciation) until the contracts are closed, when they are recorded as realized futures gains (losses).

3. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Accordingly, no provision for federal income taxes is required in the financial statements.

4. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

5. Security Lending: The fund may lend its securities to qualified institutional borrowers to earn additional income. Security loans are required to be secured at all times by collateral at least equal to the market value of securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability for the return of the collateral, during the period the securities are on loan. Security lending income represents the income earned on investing cash collateral, less expenses associated with the loan.

6. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold. Class-specific shareholder servicing fees are charged to each class at the contractual rate. Income, expenses not attributable to a specific class, and realized and unrealized gains and losses on investments are allocated to each class of shares based on its relative net assets.

19

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

B. The Vanguard Group provides investment advisory, corporate management, administrative, marketing, and distribution services and pays for all other operating expenses, except for taxes, in return for a fee calculated at an annual percentage rate of the average net assets of the fund, or, for shareholder services, each class of shares. The fund’s trustees and officers are also directors and officers of Vanguard.

C. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.

During the six months ended June 30, 2005, the fund realized $128,685,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized gains to paid-in capital.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at December 31, 2004, the fund had available realized losses of $1,838,574,000 to offset future net capital gains of $32,279,000 through December 31, 2008, $385,639,000 through December 31, 2009, $1,269,960,000 through December 31, 2010, $98,197,000 through December 31, 2011, and $52,499,000 through December 31, 2013. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending December 31, 2005; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balances above.

At June 30, 2005, net unrealized appreciation of investment securities for tax purposes was $6,216,075,000, consisting of unrealized gains of $10,713,689,000 on securities that had risen in value since their purchase and $4,497,614,000 in unrealized losses on securities that had fallen in value since their purchase.

At June 30, 2005, the aggregate settlement value of open futures contracts expiring in September 2005, and the related unrealized appreciation (depreciation) were:

		(000)
Futures Contracts	Number of Long Contracts	Aggregate Settlement Value	Unrealized Appreciation (Depreciation)
S&P 500 Index	486	$145,253	$(584)
E-mini S&P 500 Index	805	48,119	(753)

Unrealized appreciation (depreciation) on open futures contracts is required to be treated as realized gain (loss) for tax purposes.

D. During the six months ended June 30, 2005, the fund purchased $5,223,041,000 of investment securities and sold $1,633,096,000 of investment securities, other than temporary cash investments.

E. The market value of securities on loan to broker/dealers at June 30, 2005, was $162,356,000, for which the fund received cash collateral of $179,667,000.

ABOUT YOUR FUND’S EXPENSES

As a shareholder of the fund, you incur ongoing costs, which include costs for portfolio management, administrative services, and shareholder reports (like this one), among others. Operating expenses, which are deducted from a fund’s gross income, directly reduce the investment return of the fund.

A fund’s expenses are expressed as a percentage of its average net assets. This figure is known as the expense ratio. The following examples are intended to help you understand the ongoing costs (in dollars) of investing in your fund and to compare these costs with those of other mutual funds. The examples are based on an investment of $1,000 made at the beginning of the period shown and held for the entire period.

The table below illustrates your fund’s costs in two ways:

• Based on actual fund return. This section helps you to estimate the actual expenses that you paid over the period. The “Ending Account Value” shown is derived from the fund’s actual return, and the third column shows the dollar amount that would have been paid by an investor who started with $1,000 in the fund. You may use the information here, together with the amount you invested, to estimate the expenses that you paid over the period.

To do so, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number given for your fund under the heading “Expenses Paid During Period.”

• Based on hypothetical 5% yearly return. This section is intended to help you compare your fund’s costs with those of other mutual funds. It assumes that the fund had a yearly return of 5% before expenses, but that the expense ratio is unchanged. In this case—because the return used is not the fund’s actual return—the results do not apply to your investment. The example is useful in making comparisons because the Securities and Exchange Commission requires all mutual funds to calculate expenses based on a 5% return. You can assess your fund’s costs by comparing this hypothetical example with the hypothetical examples that appear in shareholder reports of other funds.

Note that the expenses shown in the table are meant to highlight and help you compare ongoing costs only and do not reflect any transactional costs or account maintenance fees. Your fund does not charge transaction fees, such as purchase or redemption fees, nor does it carry a “sales load.”

Six Months Ended June 30, 2005
Institutional Index Fund	Beginning Account Value 12/31/2004	Ending Account Value 6/30/2005	Expenses Paid During Period*
Based on Actual Fund Return
Institutional Shares	$1,000.00	$992.05	$0.25
Institutional Plus Shares	1,000.00	992.08	0.12
Based on Hypothetical 5% Yearly Return
Institutional Shares	$1,000.00	$1,024.55	$0.25
Institutional Plus Shares	1,000.00	1,024.67	0.13

* The calculations are based on expenses incurred in the most recent six-month period. The fund's annualized six-month expense ratios for that period are 0.050% for Institutional Shares and 0.025% for Institutional Plus Shares. The dollar amounts shown as "Expenses Paid" are equal to the annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent six-month period, then divided by the number of days in the most recent 12-month period.

The calculations assume no shares were bought or sold during the period. Your actual costs may have been higher or lower, depending on the amount of your investment and the timing of any purchases or redemptions.

You can find more information about the fund’s expenses, including annual expense ratios, in the Financial Statements section of this report. For additional information on operating expenses and other shareholder costs, please refer to the appropriate fund prospectus.

TRUSTEES RENEW ADVISORY ARRANGEMENT

The board of trustees of Vanguard Institutional Index Fund has renewed the fund’s investment advisory arrangement with The Vanguard Group, Inc. Vanguard—through its Quantitative Equity Group—serves as the investment advisor for the fund. The board determined that continuing the fund’s internalized management structure was in the best interests of the fund and its shareholders.

The board based its decision upon its most recent evaluation of the advisor’s investment staff, portfolio management process, and performance. The trustees considered the factors discussed below, among others. However, no single factor determined whether the board approved the arrangement. Rather, it was the totality of the circumstances that drove the board’s decision.

NATURE, EXTENT, AND QUALITY OF SERVICES

The board considered the quality of the fund’s investment management over both short- and long-term periods, and took into account the organizational depth and stability of the advisor. Vanguard has been managing investments for more than two decades. George U. Sauter, Vanguard managing director and chief investment officer, has been in the investment management business since 1985 and oversees more than $600 billion in assets (stocks and bonds). Mr. Sauter has led the Quantitative Equity Group since 1987. The Quantitative Equity Group adheres to a sound, disciplined investment management process; the team has considerable experience, stability, and depth.

The board concluded that Vanguard’s experience, stability, depth, and performance, among other factors, warranted continuation of the advisory arrangement.

INVESTMENT PERFORMANCE

The board considered the short- and long-term performance of the fund, including any periods of outperformance or underperformance of its relevant benchmark and peer group. The board noted that the fund has performed in line with expectations, and that its results have been consistent with its investment strategies. Information about the fund’s performance, including some of the data considered by the board, can be found in the “Performance Summary” section of this report.

COST

The fund’s expense ratio was far below the average expense ratio charged by funds in its peer group. The fund’s advisory expense ratio was also well below the peer-group average. Information about the fund’s expense ratio appears in the “About Your Fund’s Expenses” section of this report as well as in the “Financial Statements” section.

The board does not conduct a profitability analysis of Vanguard because of Vanguard’s unique “at-cost” structure. Unlike most other mutual fund management companies, Vanguard is owned by the funds it oversees, and produces “profits” only in the form of reduced expenses for fund shareholders.

THE BENEFIT OF ECONOMIES OF SCALE

The board of trustees concluded that the fund’s low-cost arrangement with Vanguard ensures that the fund will realize economies of scale as it grows, with the cost to shareholders declining as fund assets increase.

The board will consider whether to renew the advisory arrangement again after a one-year period.

INVEST WITH VANGUARD FOR YOUR RETIREMENT

Vanguard offers low-cost, high-quality solutions that combine a variety of investment choices to help you achieve your retirement goals.

A Vanguard traditional IRA enables you to make deductible or nondeductible contributions that can grow tax-deferred until you take distributions in retirement, while a Vanguard Roth IRA allows you to make nondeductible contributions with tax-free withdrawals when you take qualified distributions.

With either type of Vanguard IRA^®, your investment options include:

• Vanguard mutual funds

Select from our comprehensive lineup of more than 70 low-cost mutual funds suitable for retirement investing—all with no sales commissions—to help you reach your retirement goals. We offer a broad selection of stock, bond, balanced, and money market funds.

• Vanguard Target Retirement Funds

Choose a single, all-in-one portfolio that is professionally managed and well diversified. It automatically shifts from a more aggressive to a more conservative asset allocation as your target retirement date approaches, so you can leave the time-consuming details of portfolio management to Vanguard.

• Other investment options

Consolidate and build your portfolio in a single account that provides access to the universe of stocks, bonds, options, certificates of deposit (CDs), exchange-traded funds (ETFs), and non-Vanguard mutual funds through Vanguard Brokerage Services^®.

ROLLOVER OPTIONS

When you change jobs or retire, you can take greater control of your investments by rolling over your assets in an employer-sponsored retirement plan to a Vanguard IRA. To initiate a rollover, visit Vanguard.com, where you can complete our easy online application. You can also print out the application and mail it to us—or call a Vanguard retirement specialist at 800-205-6189.

For more information, visit www.vanguard.com, or call 800-662-7447 for Vanguard funds and 800-992-8327 for non-Vanguard funds offered through Vanguard Brokerage Services, to obtain a prospectus. Investment objectives, risks, charges, expenses, and other important information are contained in the prospectus; read and consider it carefully before investing.

MAXIMIZE YOUR RETIREMENT INVESTMENTS

Are you taking full advantage of your IRA? You should be. With increased contribution limits, these tax-advantaged accounts are powerful options for retirement savers. To take full advantage of your retirement account, consider these simple, but important, steps:

• Contribute the maximum amount each year.

If you invest as much in your IRA as the law allows—$4,000 for 2005 if you are under the age of 50, and $4,500 if you are aged 50 or older—you will increase your chances of meeting your retirement goals. Provided you meet the eligibility requirements, max out your contribution every year you can.

• Make automatic contributions.

You can make regular contributions to your IRA by taking advantage of Vanguard’s Automatic Investment Plan, which deducts your contributions from your bank account on a schedule you select—making retirement investing a healthy habit.

• Keep your savings on course.

Unless you’ve invested in a Vanguard Target Retirement Fund, you should rebalance your account periodically to ensure that your target asset allocations are aligned to meet your retirement objectives.

• Protect those you care about.

You determine who will receive your retirement assets after your death, so it’s important to keep your beneficiary designations up to date. They will generally override any other instructions—even those in your will.

• Adopt a long-term approach.

A successful investment strategy requires a long-term perspective and staying on course—even when the financial markets are declining. Market-timing and performance-chasing are losing strategies that can cause you to stray from the path to your retirement goals.

If you have any questions about IRAs or would like to talk to a Vanguard retirement specialist, call 800-205-6189.

CHAIRMAN'S LETTER

Dear Shareholder,

The returns from investment-grade bonds during the first half of 2005 were rather modest relative to those seen in the recent past. Rising yields weighed on prices at the short end of the maturity spectrum, while the opposite phenomenon unfolded at the longer end.

In this environment, Vanguard Institutional Total Bond Market Index Fund posted a six-month return of 2.6%.

Total Returns	Six Months Ended June 30, 2005
Vanguard Institutional Total Bond
Market Index Fund	2.6%
Lehman Aggregate Bond Index	2.5
Average Intermediate
Investment Grade Debt Fund*	2.0
*Derived from data provided by Lipper Inc.

The adjacent table presents the total return—capital change plus reinvested distributions—for the fund as well as for comparative yardsticks. The table on page 4 shows the fund’s change in share price and per-share distributions for the period.

The fund’s yield rose modestly during the period, ending at 4.39% on June 30, 0.29 percentage point higher than at the start of the year.

THE BOND MARKET’S DICHOTOMY PERSISTED

The Lehman Brothers Aggregate Bond Index, which reflects the taxable investment-grade bond market, posted a modest 2.5% return during the six months. U.S. government and municipal issues performed best, while corporate securities matched the index return, and mortgage-backed debt trailed.

The Federal Reserve Board raised the target federal funds rate in four equal steps, taking it to 3.25% by the end of the period. The yield of the

1

3-month U.S. Treasury bill moved in sync, closing the period at 3.12%. Long-term rates didn’t follow, an unusual departure from the patterns that have emerged in past periods of rate tightening. The yield of the 10-year Treasury note finished the period at 3.91%, a drop of 31 basis points (0.31 percentage point) over the six months. The yield of the 30-year Treasury bond fell 64 basis points to 4.19%.

STOCKS MADE LITTLE HEADWAY

Following a formidable rally to close out 2004, U.S. stocks at different times stumbled and surged during the first half of 2005, but the net effect was a flat finish for the broad market, as measured by the Dow Jones Wilshire 5000 Composite Index.

Investors were cheered as home-buying activity remained high by historical standards, knowing that new homeowners fuel the economy by buying appliances and other home furnishings. But the market also faced headwinds: rising short-term interest rates and gas prices (which can curtail consumer spending); slower corporate profit growth; and mounting trade and budget deficits. Some analysts wondered if even the home-buying spree was a problem, given signs that some buyers were speculating on real estate.

Value stocks—those with prices below average, given the companies’ book value and other criteria—prolonged their five-year roll of outperforming growth stocks, which dominated the market in the late 1990s. In a reversal of recent trends, returns for large-capitalization stocks topped those of the market’s smaller companies. International stocks outperformed their U.S. counterparts; however, a strengthening dollar wiped out most of that edge for U.S. investors. The dollar rallied as the gap between short-term interest rates in the States and in Europe widened.

IN AN UNUSUAL BOND MARKET, THE FUND MET ITS OBJECTIVE

At the same time the Federal Reserve Board was raising short-term interest rates, the bond market was digesting numerous economic reports that caused bond yields to respond differently at the short and long ends of the maturity spectrum. While the Fed’s actions and good news on the economic front lifted yields at the short end of the maturity spectrum, yields at the longer end declined for a variety of reasons.

The fund’s capital return for the six months was a modest 0.3%. Income was the dominant component of the total return, accounting for 2.3 percentage points. For index portfolios, of course, the main objective is to track the performance of the benchmark as closely as possible. On this count, the fund was successful in the half-year, actually outperforming the Lehman Aggregate Bond Index by a small amount despite the fund’s expense ratio.

The fund’s success in capturing the index return is a tribute to both the advisor’s skill in developing sophisticated trading and portfolio-construction methods and the portfolio’s low cost.

The fund’s success in this unusual bond-market environment is a credit to the skills of Vanguard Fixed Income Group, the fund’s advisor. The group’s proprietary trading and portfolio-construction methods, together with its skillful management, have helped Vanguard become a leading bond index fund provider. Indeed, in April 2005, our indexed bond assets under management surpassed $50 billion. Another important factor in the fund’s tight tracking, of course, is its very low costs.

A MEASURE OF CONFIDENCE AMID UNCERTAINTY

With the onset of rising short-term interest rates more than a year ago, most investors assumed that higher rates would filter through to all maturity levels across the spectrum, as that was the typical pattern in the bond market. To this point, though, what we have witnessed has been anything but “typical.” Although short-term yields have risen markedly, those increases have not carried over to longer-maturity bond yields.

While it is no cause for alarm, this phenomenon highlights just one of the many uncertainties that bond investing entails. In light of those uncertainties, the benefits of indexing become more evident. Investing in a broad-market bond index fund can give your institution a reasonable

3

level of confidence that it will not miss out on a significant part of the bond market’s return, while also enhancing the predictability of the relative returns your institution can expect to receive on its investment.

As always, we appreciate your confidence in Vanguard.

Sincerely,

John J. Brennan
CHAIRMAN AND CHIEF EXECUTIVE OFFICER

GLOSSARY OF INVESTMENT TERMS

Average Coupon. The average interest rate paid on the fixed income securities held by a fund. It is expressed as a percentage of face value.

Average Duration. An estimate of how much the value of the bonds held by a fund will fluctuate in response to a change in interest rates. To see how the value could change, multiply the average duration by the change in rates. If interest rates rise by 1 percentage point, the value of the bonds in a fund with an average duration of five years would decline by about 5%. If rates decrease by a percentage point, the value would rise by 5%.

Average Effective Maturity. The average length of time until fixed income securities held by a fund reach maturity and are repaid, taking into consideration the possibility that the issuer may call the bond before its maturity date. The figure reflects the proportion of fund assets represented by each security; it also reflects any futures contracts held. In general, the longer the average effective maturity, the more a fund’s share price will fluctuate in response to changes in market interest rates.

Average Quality. An indicator of credit risk, this figure is the average of the ratings assigned to a fund’s fixed income holdings by credit-rating agencies. The agencies make their judgment after appraising an issuer’s ability to meet its obligations. Quality is graded on a scale, with Aaa or AAA indicating the most creditworthy bond issuers. U.S. Treasury securities are considered to have the highest credit quality.

Beta. A measure of the magnitude of a fund’s past share-price fluctuations in relation to the ups and downs of a given market index. The index is assigned a beta of 1.00. Compared with a given index, a fund with a beta of 1.20 typically would have seen its share price rise or fall by 12% when the index rose or fell by 10%. A fund’s beta should be reviewed in conjunction with its R-squared (see definition below). The lower the R-squared, the less correlation there is between the fund and the index, and the less reliable beta is as an indicator of volatility.

Expense Ratio. The percentage of a fund’s average net assets used to pay its annual administrative and advisory expenses. These expenses directly reduce returns to investors.

R-Squared. A measure of how much of a fund’s past returns can be explained by the returns from the market in general, as measured by a given index. If a fund’s total returns were precisely synchronized with an index’s returns, its R-squared would be 1.00. If the fund’s returns bore no relationship to the index’s returns, its R-squared would be 0.

Short-Term Reserves. The percentage of a fund invested in highly liquid, short-term securities that can be readily converted to cash.

Yield. A snapshot of a fund’s interest income. The yield, expressed as a percentage of the fund’s net asset value, is based on income earned over the past 30 days (7 days for money market funds) and is annualized, or projected forward for the coming year.

Yield to Maturity. The rate of return an investor would receive if the fixed income securities held by a fund were held to their maturity dates.

As of 6/30/2005 FINANCIAL STATEMENTS (UNAUDITED)

STATEMENT OF NET ASSETS

This Statement provides a detailed list of the fund's holdings, including each security's market value on the last day of the reporting period. Securities are grouped and subtotaled by bond type (U.S. government and agency issues, corporate bonds, sovereign bonds, etc.); corporate bonds are further classified by industry sector. Other assets are added to, and liabilities are subtracted from, the value of Total Investments to calculate the fund's Net Assets. Finally, Net Assets are divided by the outstanding shares of the fund to arrive at its share price, or Net Asset Value (NAV) Per Share.

At the end of the Statement of Net Assets, you will find a table displaying the composition of the fund's net assets. Undistributed Net Investment Income is minimal because the fund distributes its net income to shareholders as a dividend each day. Any realized gains must be distributed annually, so the bulk of net assets consists of Paid-in Capital (money invested by shareholders). The balance shown for Accumulated Net Realized Gains usually approximates the amount available to distribute to shareholders as capital gains as of the statement date, but may differ because certain investments or transactions may be treated differently for financial statement and tax purposes. Any Accumulated Net Realized Losses, and any cumulative excess of distributions over net realized gains, will appear as negative balances. Unrealized Appreciation (Depreciation) is the difference between the value of the fund's investments and their cost, and reflects the gains (losses) that would be realized if the fund were to sell all of its investments at their statement-date values.

The fund provides a complete list of its holdings four times in each fiscal year, at the quarter-ends. For the second and fourth fiscal quarters, the lists appear in the fund's semiannual and annual reports to shareholders. For the first and third fiscal quarters, the fund files the lists with the Securities and Exchange Commission on Form N-Q. Shareholders can look up the fund's Forms N-Q on the SEC's website at www.sec.gov. Forms N-Q may also be reviewed and copied at the SEC's Public Reference Room (see the back cover of this report for further information).

STATEMENT OF CHANGES IN NET ASSETS

This Statement shows how the fund’s total net assets changed during the two most recent reporting periods. The Operations section summarizes information detailed in the Statement of Operations. Because the fund distributes its income to shareholders each day, the amounts of Distributions—Net Investment Income approximate the net income earned as shown under the Operations section. The amounts of Distributions—Realized Capital Gain may not match the capital gains shown in the Operations section, because distributions are determined on a tax basis and may be made in a period different from the one in which the gains were realized on the financial statements. The Capital Share Transactions section shows the amount shareholders invested in the fund, either by purchasing shares or by reinvesting distributions, as well as the amounts redeemed. The corresponding numbers of Shares Issued and Redeemed are shown at the end of the Statement.

FINANCIAL HIGHLIGHTS

This table summarizes the fund’s investment results and distributions to shareholders on a per-share basis. It also presents the Total Return and shows net investment income and expenses as percentages of average net assets. These data will help you assess: the variability of the fund’s net income and total returns from year to year; the relative contributions of net income and capital gains to the fund’s total return; how much it costs to operate the fund; and the extent to which the fund tends to distribute capital gains. The table also shows the Portfolio Turnover Rate, a measure of trading activity. A turnover rate of 100% means that the average security is held in the fund for one year.

NOTES TO FINANCIAL STATEMENTS

Vanguard Institutional Total Bond Market Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund is offered to investors who meet certain administrative and servicing criteria and invest a minimum of $100 million. Certain of the fund’s investments are in corporate debt instruments; the issuers’ abilities to meet their obligations may be affected by economic developments in their respective industries.

A.   The following significant accounting policies conform to generally accepted accounting principles for U.S. mutual funds. The fund consistently follows such policies in preparing its financial statements.

1. Security Valuation: Bonds, and temporary cash investments acquired over 60 days to maturity, are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Investments in Vanguard Market Liquidity Fund are valued at that fund’s net asset value. Other temporary cash investments are valued at amortized cost, which approximates market value. Securities for which market quotations are not readily available, or whose values have been materially affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued by methods deemed by the board of trustees to represent fair value.

2.  Mortgage-Dollar-Rolls: The fund has entered into mortgage-dollar-roll transactions, in which the fund sells mortgage-backed securities to a dealer and simultaneously agrees to purchase similar securities in the future at a predetermined price. The proceeds of the securities sold in mortgage-dollar-roll transactions are invested in high-quality short-term fixed income securities. The fund forgoes principal and interest paid on the securities, and is compensated by interest earned on the proceeds of the initial sale and by a lower price on the securities to be repurchased. The fund accounts for mortgage-dollar-roll transactions as purchases and sales; as such, these transactions may increase the fund’s portfolio turnover rate. Amounts to be received or paid in connection with open mortgage-dollar-rolls are included in Receivables for Investment Securities Sold or Payables for Investment Securities Purchased in the Statement of Net Assets. The primary risk associated with mortgage-dollar-rolls is that a counterparty will default on its obligations to deliver purchased securities.

3.  Swap Contracts: The fund has entered into swap transactions to earn the total return on a specified security or index of fixed income securities. Under the terms of the swaps, the fund receives the total return (either receiving the increase or paying the decrease) on a reference security or index, applied to a notional principal amount. In return, the fund agrees to pay the counterparty a floating rate, which is reset periodically based on short-term interest rates, applied to the same notional amount. At the same time, the fund invests an amount equal to the notional amount of the swaps in high-quality floating-rate securities.

The notional amounts of swap contracts are not recorded in the financial statements. Swaps are valued daily, and the change in value is recorded as unrealized appreciation (depreciation) until the termination of the swap, at which time realized gain (loss) is recorded. The primary risk associated with total return swaps is that a counterparty will default on its obligation to pay net amounts due to the fund.

4.  Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its income. Accordingly, no provision for federal income taxes is required in the financial statements.

5. Distributions: Distributions from net investment income are declared daily and paid on the first business day of the following month. Annual distributions from realized capital gains, if any, are recorded on the ex-dividend date.

6.  Security Lending: The fund may lend its securities to qualified institutional borrowers to earn additional income. Security loans are required to be secured at all times by collateral (cash or U.S. government and agency securities) at least equal to the market value of securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability for the return of the collateral, during the period the securities are on loan. Security lending income represents the income earned on investing cash collateral, and/or fees received from borrowers, less expenses associated with the loan.

36

7.  Other: Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Premiums and discounts on debt securities purchased are amortized and accreted, respectively, to interest income over the lives of the respective securities. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

B. The Vanguard Group provides investment advisory, corporate management, administrative, marketing, and distribution services and pays for all other operating expenses, except for taxes, in return for a fee calculated at an annual percentage rate of the average net assets of the fund. The fund’s trustees and officers are also directors and officers of Vanguard.

C. Capital gain distributions are determined on a tax basis and may differ from realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when gains or losses are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year.

During the six months ended June 30, 2005, the fund realized $1,376,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized gains to paid-in capital.

Realized and unrealized gains (losses) on certain of the fund’s swap contracts are treated as ordinary income (loss) for tax purposes; the effect on the fund’s income dividends to shareholders is offset by a change in principal return. Realized gains of $802,000 on swap contracts have been reclassified from accumulated net realized gains to undistributed net investment income. Taxable income on swap contracts is accumulated monthly and included in income dividends paid to shareholders in the following month. At June 30, 2005, the fund had $224,000 of net swap gains available to distribute to shareholders as ordinary income dividends.

At June 30, 2005, net unrealized appreciation of investment securities for tax purposes was $16,898,000, consisting of unrealized gains of $20,780,000 on securities that had risen in value since their purchase and $3,882,000 in unrealized losses on securities that had fallen in value since their purchase.

At June 30, 2005, the fund had the following open swap contracts:

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

D.   During the six months ended June 30, 2005, the fund purchased $150,118,000 of investment securities and sold $215,325,000 of investment securities other than U.S. government securities and temporary cash investments. Purchases and sales of U.S. government securities were $275,420,000 and $285,089,000, respectively.

ABOUT YOUR FUND'S EXPENSES

As a shareholder of the fund, you incur ongoing costs, which include costs for portfolio management, administrative services, and shareholder reports (like this one), among others. Operating expenses, which are deducted from a fund’s gross income, directly reduce the investment return of the fund. A fund’s expenses are expressed as a percentage of its average net assets. This figure is known as the expense ratio. The following examples are intended to help you understand the ongoing costs (in dollars) of investing in your fund and to compare these costs with those of other mutual funds. The examples are based on an investment of $1,000 made at the beginning of the period shown and held for the entire period.

The table below illustrates your fund’s costs in two ways:

• Based on actual fund return. This section helps you to estimate the actual expenses that you paid over the period. The “Ending Account Value” shown is derived from the fund’s actual return, and the third column shows the dollar amount that would have been paid by an investor who started with $1,000 in the fund. You may use the information here, together with the amount you invested, to estimate the expenses that you paid over the period.

To do so, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number given for your fund under the heading “Expenses Paid During Period.”

• Based on hypothetical 5% yearly return. This section is intended to help you compare your fund’s costs with those of other mutual funds. It assumes that the fund had a yearly return of 5% before expenses, but that the expense ratio is unchanged. In this case—because the return used is not the fund’s actual return—the results do not apply to your investment. The example is useful in making comparisons because the Securities and Exchange Commission requires all mutual funds to calculate expenses based on a 5% return. You can assess your fund’s costs by comparing this hypothetical example with the hypothetical examples that appear in shareholder reports of other funds.

Six Months Ended June 30, 2005
Institutional Total Bond Market Index Fund	Beginning Account Value 12/31/2004	Ending Account Value 6/30/2005	Expenses Paid During Period*
Based on Actual
Fund Return	$1,000.00	$1,025.70	$0.25
Based on Hypothetical
5% Yearly Return	$1,000.00	$1,024.55	$0.25
*The calculations are based on expenses incurred in the most recent six-month period. The fund’s annualized six-month expense ratio for that period is 0.05%. The dollar amounts shown as “Expenses Paid” are equal to the annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent six-month period, then divided by the number of days in the most recent 12-month period.

Note that the expenses shown in the table are meant to highlight and help you compare ongoing costs only and do not reflect any transactional costs or account maintenance fees. Your fund does not charge transaction fees, such as purchase or redemption fees, nor does it carry a “sales load.”

The calculations assume no shares were bought or sold during the period. Your actual costs may have been higher or lower, depending on the amount of your investment and the timing of any purchases or redemptions.

You can find more information about the fund’s expenses in the Financial Statements section of this report. For additional information on operating expenses and other shareholder costs, please refer to the prospectus.

TRUSTEES RENEW ADVISORY ARRANGEMENT

The board of trustees of Vanguard Institutional Total Bond Market Index Fund has renewed the fund’s investment advisory arrangement with The Vanguard Group, Inc. Vanguard—through its Fixed Income Group—serves as the investment advisor for the fund. The board determined that continuing the fund’s internalized management structure was in the best interests of the fund and its shareholders.

The board based its decision upon its most recent evaluation of the advisor’s investment staff, portfolio management process, and performance. The trustees considered the factors discussed below, among others. However, no single factor determined whether the board approved the arrangement. Rather, it was the totality of the circumstances that drove the board’s decision.

NATURE, EXTENT, AND QUALITY OF SERVICES

The board considered the quality of the fund’s investment management over both short- and long-term periods, and took into account the organizational depth and stability of the advisor. Vanguard has been managing investments for more than two decades. George U. Sauter, Vanguard managing director and chief investment officer, has been in the investment management business since 1985 and oversees more than $600 billion in assets (stocks and bonds). Robert F. Auwaerter, principal in charge of the Fixed Income Group, has been in the investment management business since 1978. The Fixed Income Group adheres to a sound, disciplined investment management process; the team has considerable experience, stability, and depth.

The board concluded that Vanguard’s experience, stability, depth, and performance, among other factors, warranted continuation of the advisory arrangement.

INVESTMENT PERFORMANCE

The board considered the short- and long-term performance of the fund, including any periods of outperformance or underperformance of its relevant benchmark and peer group. The board noted that the fund has performed in line with expectations, and that its results have been consistent with its investment strategies. Information about the fund’s performance, including some of the data considered by the board, can be found in the “Performance Summary” section of this report.

COS

The fund’s expense ratio was far below the average expense ratio charged by funds in its peer group. The fund’s advisory expense ratio was also well below its peer-group average. Information about the fund’s expense ratio appears in the “About Your Fund’s Expenses” section of this report as well as in the “Financial Statements” section.

The board does not conduct a profitability analysis of Vanguard because of Vanguard’s unique “at-cost” structure. Unlike most other mutual fund management companies, Vanguard is owned by the funds it oversees, and produces “profits” only in the form of reduced expenses for fund shareholders.

THE BENEFIT OF ECONOMIES OF SCALE

The board of trustees concluded that Vanguard Institutional Total Bond Market Index Fund’s low-cost arrangement with Vanguard ensures that the fund will realize economies of scale as it grows, with the cost to shareholders declining as fund assets increase.

The board will consider whether to renew the advisory arrangement again after a one-year period.

CHAIRMAN’S LETTER

Dear Shareholder,

U.S. stock prices finished the first half of 2005 mostly flat, as the market’s weak spots subsumed its pockets of strength.The stocks of energy-related companies—beneficiaries of persistently high oil prices—were among the strongest performers, while technology and consumer discretionary stocks struggled. Vanguard Institutional Total Stock Market Index Fund succeeded in capturing the return of the broad market.

The adjacent table presents the total returns of the fund’s two share classes and its target index, as well as the average return of its peer group. Starting and ending net asset values for each share class, as well as income distributions, appear in a table on page 4.

During the half-year, the fund switched its target benchmark from the Dow Jones Wilshire 5000 Composite Index to the MSCI US Broad Market Index, another measure of the broad market. The new benchmark incorporates many of Vanguard’s views of “best practices” in index construction, including:

• Market weightings based on stocks’ “float”—those shares that are readily available to the public.
• Inclusion of both companies incorporated in the United States, and internationally based companies with equity trading activity, shareholders, and operations predominantly in the United States.
• Exclusion of limited partnerships.

STOCKS MADE LITTLE HEADWAY

Following a formidable rally to close out 2004, U.S. stocks at different times stumbled and surged during the first half of 2005, but the net effect was a flat finish for the broad market, as measured by the Dow Jones Wilshire 5000 Index.

Investors were cheered as home-buying activity remained high by historical standards, knowing that new homeowners fuel the economy by buying appliances and other home furnishings. But the market also faced headwinds: rising short-term interest rates and gas prices (which can curtail consumer spending); slower corporate profit growth; and mounting trade and budget deficits.

Value stocks—those with low prices relative to corporate earnings, book value, and other measures—extended their five-year winning streak over growth stocks, which dominated the market in the late 1990s. In a reversal of recent trends, returns for large-cap stocks topped those of the market’s smaller companies. International stocks outperformed their U.S. counterparts; however, a strengthening dollar wiped out most of that edge for U.S. investors.

THE BOND MARKET’S DICHOTOMY PERSISTED

The Lehman Brothers Aggregate Bond Index, which reflects the performance of the taxable investment-grade bond market, returned a modest 2.5% during the six months. U.S. government and municipal issues performed best. Corporate securities matched the index return, and mortgage-backed debt trailed.

The Federal Reserve Board raised its target for the federal funds rate in four equal steps by a total of 1 percentage point, to 3.25%. The yield

of the 3-month U.S. Treasury bill moved in sync, closing the period at 3.12%. Long-term rates did not follow. The yield of the 10-year Treasury note finished the period at 3.91%, a drop of 31 basis points (0.31 percentage point) over the six months. The yield of the 30-year Treasury bond fell 64 basis points to 4.19%.

ENERGY STOCKS RALLIED, WHILE TECH SHARES STRUGGLED

The broad stock market’s flat performance masked significant variation among different market sectors. Energy-related stocks, for example, registered solid double-digit gains, as fuel prices continued to hover at unprecedented heights. Health care stocks were another pocket of strength, bolstered by excellent returns from the stocks of HMOs and other health-insurance providers.

These gains were offset by weak showings from technology, consumer discretionary and, to a lesser extent, auto & transportation stocks. The technology sector was buffeted by high-profile earnings disappointments, while consumer discretionary stocks retreated on weakness in select retailers. The relatively small auto & transportation sector was hit hard by the widely publicized woes of auto giants General Motors and Ford.

The fund captured the return of its target benchmark, sacrificing minimal return to the real-world transaction and operating costs incurred by funds but not by indexes. Such precision is a product of the proprietary-trading and portfolio-construction methodologies developed by Vanguard Quantitative Equity Group, the fund’s advisor. The fund’s low costs are, naturally, another critical element in keeping returns close to those of the benchmark.

TIMELESS ADVICE FOR ‘NOW’

The markets and the news media tend to focus on what to do “now.” As we never get tired of reminding our clients, successful long-term investing doesn’t mean paying attention to yesterday’s performance, today’s news, or predictions for tomorrow. Instead, reaching the long-term goals—of an institution or of an individual—requires a more patient approach—an approach that Vanguard’s index funds are ideally suited to support.

Whether the stock market rises or falls sharply, or, as in the past six months, meanders sideways, the low-cost, broadly diversified Vanguard

GLOSSARY OF INVESTMENT TERMS

Beta. A measure of the magnitude of a fund’s past share-price fluctuations in relation to the ups and downs of a given market index. The index is assigned a beta of 1.00. Compared with a given index, a fund with a beta of 1.20 typically would have seen its share price rise or fall by 12% when the index rose or fell by 10%. A fund’s beta should be reviewed in conjunction with its R-squared (see definition below). The lower the R-squared, the less correlation there is between the fund and the index, and the less reliable beta is as an indicator of volatility.

Earnings Growth Rate. The average annual rate of growth in earnings over the past five years for the stocks now in a fund.

Expense Ratio. The percentage of a fund’s average net assets used to pay its annual administrative and advisory expenses. These expenses directly reduce returns to investors.

Foreign Holdings. The percentage of a fund’s equity assets represented by stocks or depositary receipts of companies based outside the United States.

Median Market Cap. 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.

Price/Book Ratio. The share price of a stock divided by its net worth, or book value, per share. For a fund, the weighted average price/book ratio of the stocks it holds.

Price/Earnings Ratio. The ratio of a stock’s current price to its per-share earnings over the past year. For a fund, the weighted average P/E of the stocks it holds. P/E is an indicator of market expectations about corporate prospects; the higher the P/E, the greater the expectations for a company’s future growth.

R-Squared. A measure of how much of a fund’s past returns can be explained by the returns from the market in general, as measured by a given index. If a fund’s total returns were precisely synchronized with an index’s returns, its R-squared would be 1.00. If the fund’s returns bore no relationship to the index’s returns, its R-squared would be 0.

Return on Equity. The annual average rate of return generated by a company during the past five years for each dollar of shareholder’s equity (net income divided by shareholder’s equity). For a fund, the weighted average return on equity for the companies whose stocks it holds.

Short-Term Reserves. The percentage of a fund invested in highly liquid, short-term securities that can be readily converted to cash.

Turnover Rate. An indication of the fund’s trading activity. Funds with high turnover rates incur higher transaction costs and may be more likely to distribute capital gains (which may be taxable to investors). The turnover rate excludes in-kind transactions, which have minimal impact on costs.

Yield. A snapshot of a fund’s income from interest and dividends. The yield, expressed as a percentage of the fund’s net asset value, is based on income earned over the past 30 days and is annualized, or projected forward for the coming year. The index yield is based on the current annualized rate of income provided by securities in the index.

PERFORMANCE SUMMARY

As of 6/30/2005 All of the returns in this report represent past performance, which is not a guarantee of future results that may be achieved by the fund. (For performance data current to the most recent month-end, which may be higher or lower than that cited, visit our website at www.vanguard.com.) Note, too, that both investment returns and principal value can fluctuate widely, so an investor’s shares, when sold, could be worth more or less than their original cost. The returns shown do not reflect taxes that a shareholder would pay on fund distributions or on the sale of fund shares.

As of 6/30/2005 FINANCIAL STATEMENTS (UNAUDITED)

STATEMENT OF NET ASSETS

This Statement provides a detailed list of the fund’s holdings, including each security’s market value on the last day of the reporting period. Securities are grouped and subtotaled by asset type (common stocks, bonds, etc.) and by industry sector. Other assets are added to, and liabilities are subtracted from, the value of Total Investments to calculate the fund’s Net Assets. Finally, Net Assets are divided by the outstanding shares of the fund to arrive at its share price, or Net Asset Value (NAV) Per Share.

At the end of the Statement of Net Assets, you will find a table displaying the composition of the fund’s net assets. Because all income and any realized gains must be distributed to shareholders each year, the bulk of net assets consists of Paid-in Capital (money invested by shareholders). The amounts shown for Undistributed Net Investment Income and Accumulated Net Realized Gains usually approximate the sums the fund had available to distribute to shareholders as income dividends or capital gains as of the statement date, but may differ because certain investments or transactions may be treated differently for financial statement and tax purposes. Any Accumulated Net Realized Losses, and any cumulative excess of distributions over net income or net realized gains, will appear as negative balances. Unrealized Appreciation (Depreciation) is the difference between the market value of the fund’s investments and their cost, and reflects the gains (losses) that would be realized if the fund were to sell all of its investments at their statement-date values.

The fund provides a complete list of its holdings four times in each fiscal year, at the quarter-ends. For the second and fourth fiscal quarters, the lists appear in the fund’s semiannual and annual reports to shareholders. For the first and third fiscal quarters, the fund files the lists with the Securities and Exchange Commission on Form N-Q. Shareholders can look up the fund’s Forms N-Q on the SEC’s website at www.sec.gov. Forms N-Q may also be reviewed and copied at the SEC’s Public Reference Room (see the back cover of this report for further information).

STATEMENT OF CHANGES IN NET ASSETS

This Statement shows how the fund’s total net assets changed during the two most recent reporting periods. The Operations section summarizes information detailed in the Statement of Operations. The amounts shown as Distributions to shareholders from the fund’s net income and capital gains may not match the amounts shown in the Operations section, because distributions are determined on a tax basis and may be made in a period different from the one in which the income was earned or the gains were realized on the financial statements. The Capital Share Transactions section shows the net amount shareholders invested in or redeemed from the fund. Distributions and Capital Share Transactions are shown separately for each class of shares.

FINANCIAL HIGHLIGHTS

This table summarizes the fund’s investment results and distributions to shareholders on a per-share basis for each class of shares. It also presents the Total Return and shows net investment income and expenses as percentages of average net assets. These data will help you assess: the variability of the fund’s net income and total returns from year to year; the relative contributions of net income and capital gains to the fund’s total return; how much it costs to operate the fund; and the extent to which the fund tends to distribute capital gains. The table also shows the Portfolio Turnover Rate, a measure of trading activity. A turnover rate of 100% means that the average security is held in the fund for one year.

NOTES TO FINANCIAL STATEMENTS

Vanguard Institutional Total Stock Market Index Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares, Institutional Shares and Institutional Plus Shares, to investors who invest minimum amounts of $100 million and $200 million, respectively.

A. The following significant accounting policies conform to generally accepted accounting principles for U.S. mutual funds. The fund consistently follows such policies in preparing its financial statements.

1. Security Valuation: Securities are valued as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date. Equity securities are valued at the latest quoted sales prices or official closing prices taken from the primary market in which each security trades; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Securities for which market quotations are not readily available, or whose values have been materially affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued by methods deemed by the board of trustees to represent fair value. Investments in Vanguard Market Liquidity Fund are valued at that fund’s net asset value. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value.

2. Futures Contracts: The fund uses index futures contracts to a limited extent, with the objectives of maintaining full exposure to the stock market, enhancing returns, maintaining liquidity, and minimizing transaction costs. The fund may purchase futures contracts to immediately invest incoming cash in the market, or sell futures in response to cash outflows, thereby simulating a fully invested position in the underlying index while maintaining a cash balance for liquidity. The fund may seek to enhance returns by using futures contracts instead of the underlying securities when futures are believed to be priced more attractively than the underlying securities. The primary risks associated with the use of futures contracts are imperfect correlation between changes in market values of stocks held by the fund and the prices of futures contracts, and the possibility of an illiquid market.

Futures contracts are valued at their quoted daily settlement prices. The aggregate principal amounts of the contracts are not recorded in the financial statements. Fluctuations in the value of the contracts are recorded in the Statement of Net Assets as an asset (liability) and in the Statement of Operations as unrealized appreciation (depreciation) until the contracts are closed, when they are recorded as realized futures gains (losses).

3. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its taxable income. Accordingly, no provision for federal income taxes is required in the financial statements.

4. Distributions: Distributions to shareholders are recorded on the ex-dividend date.

5. Security Lending: The fund may lend its securities to qualified institutional borrowers to earn additional income. Security loans are required to be secured at all times by collateral at least equal to the market value of securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability for the return of the collateral, during the period the securities are on loan. Security lending income represents the income earned on investing cash collateral, less expenses associated with the loan.

6. Other: Dividend income is recorded on the ex-dividend date. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold. Class-specific shareholder servicing fees are charged to each class at the contractual rate. Income, expenses not attributable to a specific class, and realized and unrealized gains and losses on investments are allocated to each class of shares based on its relative net assets.

48

B. The Vanguard Group provides investment advisory, corporate management, administrative, marketing, and distribution services and pays for all other operating expenses, except for taxes, in return for a fee calculated at an annual percentage rate of the average net assets of the fund or, for shareholder services, each class of shares. The fund’s trustees and officers are also directors and officers of Vanguard.

C. Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.

During the six months ended June 30, 2005, the fund realized $32,475,000 of net capital gains resulting from in-kind redemptions—in which shareholders exchanged fund shares for securities held by the fund rather than for cash. Because such gains are not taxable to the fund, and are not distributed to shareholders, they have been reclassified from accumulated net realized gains to paid-in capital.

The fund’s tax-basis capital gains and losses are determined only at the end of each fiscal year. For tax purposes, at December 31, 2004, the fund had available realized losses of $155,805,000 to offset future net capital gains of $4,981,000 through December 31, 2009, $99,548,000 through December 31, 2010, $44,357,000 through December 31, 2011, $5,005,000 through December 31, 2012, and $1,914,000 through December 31, 2013. The fund will use these capital losses to offset net taxable capital gains, if any, realized during the year ending December 31, 2005; should the fund realize net capital losses for the year, the losses will be added to the loss carryforward balances above.

At June 30, 2005, net unrealized appreciation of investment securities for tax purposes was $125,933,000, consisting of unrealized gains of $218,520,000 on securities that had risen in value since their purchase and $92,587,000 in unrealized losses on securities that had fallen in value since their purchase.

At June 30, 2005, the aggregate settlement value of open futures contracts expiring in September 2005 and the related unrealized appreciation (depreciation) were:

ABOUT YOUR FUND’S EXPENSES

As a shareholder of the fund, you incur ongoing costs, which include costs for portfolio management, administrative services, and shareholder reports (like this one), among others. Operating expenses, which are deducted from a fund’s gross income, directly reduce the investment return of the fund. A fund’s expenses are expressed as a percentage of its average net assets. This figure is known as the expense ratio. The following examples are intended to help you understand the ongoing costs (in dollars) of investing in your fund and to compare these costs with those of other mutual funds. The examples are based on an investment of $1,000 made at the beginning of the period shown and held for the entire period. The table below illustrates your fund’s costs in two ways:

• Based on actual fund return. This section helps you to estimate the actual expenses that you paid over the period. The “Ending Account Value” shown is derived from the fund’s actual return, and the third column shows the dollar amount that would have been paid by an investor who started with $1,000 in the fund. You may use the information here, together with the amount you invested, to estimate the expenses that you paid over the period. To do so, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number given for your fund under the heading “Expenses Paid During Period.”

• Based on hypothetical 5% yearly return. This section is intended to help you compare your fund’s costs with those of other mutual funds. It assumes that the fund had a yearly return of 5% before expenses, but that the expense ratio is unchanged. In this case—because the return used is not the fund’s actual return—the results do not apply to your investment. The example is useful in making comparisons because the Securities and Exchange Commission requires all mutual funds to calculate expenses based on a 5% return. You can assess your fund’s costs by comparing this hypothetical example with the hypothetical examples that appear in shareholder reports of other funds.

Six Months Ended June 30, 2005
Institutional Total Stock Market Index Fund	Beginning Account Value 12/31/2004	Ending Account Value 6/30/2005	Expenses Paid During Period*
Based on Actual Fund Return
Institutional Shares	$1,000.00	$998.19	$0.25
Institutional Plus Shares	1,000.00	998.31	0.12
Based on Hypothetical 5% Yearly Return
Institutional Shares	$1,000.00	$1,024.55	$0.25
Institutional Plus Shares	1,000.00	1,024.67	0.13
*The calculations are based on expenses incurred in the most recent six-month period. The fund’s annualized six-month expense ratios for that period are 0.05% for Institutional Shares and 0.025% for Institutional Plus Shares. The dollar amounts shown as “Expenses Paid” are equal to the annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent six-month period, then divided by the number of days in the most recent 12-month period.

Note that the expenses shown in the table are meant to highlight and help you compare ongoing costs only and do not reflect any transactional costs or account maintenance fees. Your fund does not charge transaction fees, such as purchase or redemption fees, nor does it carry a “sales load.”

The calculations assume no shares were bought or sold during the period. Your actual costs may have been higher or lower, depending on the amount of your investment and the timing of any purchases or redemptions.

You can find more information about the fund’s expenses, including annual expense ratios, in the Financial Statements section of this report. For additional information on operating expenses and other shareholder costs, please refer to the fund prospectus.

TRUSTEES RENEW ADVISORY ARRANGEMENT

The board of trustees of Vanguard Institutional Total Stock Market Index Fund has renewed the fund’s investment advisory arrangement with The Vanguard Group, Inc. Vanguard—through its Quantitative Equity Group—serves as the investment advisor for the fund. The board determined that continuing the fund’s internalized management structure was in the best interests of the fund and its shareholders.

The board based its decision upon its most recent evaluation of the advisor’s investment staff, portfolio management process, and performance. The trustees considered the factors discussed below, among others. However, no single factor determined whether the board approved the arrangement. Rather, it was the totality of the circumstances that drove the board’s decision.

NATURE, EXTENT, AND QUALITY OF SERVICES

The board considered the quality of the fund’s investment management over both short- and long-term periods, and took into account the organizational depth and stability of the advisor. Vanguard has been managing investments for more than two decades. George U. Sauter, Vanguard managing director and chief investment officer, has been in the investment management business since 1985 and oversees more than $600 billion in assets (stocks and bonds). Mr. Sauter has led the Quantitative Equity Group since 1987. The Quantitative Equity Group adheres to a sound, disciplined investment management process; the team has considerable experience, stability, and depth.

The board concluded that Vanguard’s experience, stability, depth, and performance, among other factors, warranted continuation of the advisory arrangement.

INVESTMENT PERFORMANCE

The board considered the short- and long-term performance of the fund, including any periods of outperformance or underperformance of its relevant benchmark and peer group. The board noted that the fund has performed in line with expectations, and that its results have been consistent with its investment strategies. Information about the fund’s performance, including some of the data considered by the board, can be found in the “Performance Summary” section of this report.

COST

The fund’s expense ratio was far below the average expense ratio charged by funds in its peer group. The fund’s advisory expense ratio was also well below its peer-group average. Information about the fund’s expense ratio appears in the “About Your Fund’s Expenses” section of this report as well as in the “Financial Statements” section.

The board does not conduct a profitability analysis of Vanguard because of Vanguard’s unique “at-cost” structure. Unlike most other mutual fund management companies, Vanguard is owned by the funds it oversees, and produces “profits” only in the form of reduced expenses for fund shareholders.

THE BENEFIT OF ECONOMIES OF SCALE

The board of trustees concluded that Vanguard Institutional Total Stock Market Index Fund’s low-cost arrangement with Vanguard ensures that the fund will realize economies of scale as it grows, with the cost to shareholders declining as fund assets increase.

The board will consider whether to renew the advisory arrangement again after a one-year period.
