Portfolio Summary

Investment Objective

The Portfolio seeks to provide a high level of income and moderate long-term capital appreciation by tracking the performance of a benchmark index that measures the performance of publicly traded equity REITs and other real estate-related investments.

Fees and Expenses

The following table describes the fees and expenses you may pay if you buy and hold shares of the Portfolio. The expenses shown in the table and in the example that follows do not reflect additional fees and expenses associated with the annuity or life insurance program through which you invest. If those additional fees and expenses were included, overall expenses would be higher.

Annual Portfolio Operating Expenses

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

Management Fees XX.XX%
12b-1 Distribution Fee None
Other Expenses XX.XX%
Total Annual Portfolio Operating Expenses XX.XX%

 

Example

The following example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. It illustrates the hypothetical expenses that you would incur over various periods if you were to invest $10,000 in the Portfolio’s shares. This example assumes that the Portfolio provides a return of 5% each year and that total annual portfolio operating expenses remain as stated in the preceding table. You would incur these hypothetical expenses 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
$XX $XX $XX $XX

Portfolio Turnover

The Portfolio 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. These costs, which are not reflected in annual portfolio operating expenses or in the previous expense example, reduce the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover rate was xx% of the average value of its portfolio.

Principal Investment Strategies

The Portfolio employs an indexing investment approach designed to track the performance of the MSCI US Investable Market Real Estate 25/50 Index . The Index is made up of stocks of large, mid-size, and small U.S. companies within the real estate sector, as classified under the Global Industry Classification Standard (GICS). The GICS real estate sector is composed of equity real estate investment trusts (known as REITs), which includes specialized REITs, and real estate management and development companies . The Portfolio attempts to replicate the Index by investing all, or substantially all, of its assets in the stocks that make up the Index, holding each stock in approximately the same proportion as its weighting in the Index.

Principal Risks

An investment in the Portfolio could lose money over short or even long periods. You should expect the Portfolio’s share price and total return to fluctuate within a wide range . The Portfolio is subject to the following risks, which could affect the Portfolio’s performance:

Industry concentration risk, which is the chance that the stocks of REITs and other real estate-related investments will decline because of adverse developments affecting the real estate industry and real property values. Because the Portfolio concentrates its assets in these stocks, industry concentration risk is high.

Stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices. The Portfolio’s target index may, at times, become focused in stocks of a limited number of companies, which could cause the Portfolio to underperform the overall stock market.

Asset concentration risk , which is the chance that, because the Portfolio’s target index (and therefore the Portfolio) tends to be heavily weighted in its ten largest holdings, the Portfolio’s performance may be hurt disproportionately by the poor performance of relatively few stocks.

2


 

Interest rate risk, which is the chance that REIT stock prices overall will decline and that the cost of borrowing for REITs will increase because of rising interest rates. Interest rate risk is high for the Portfolio.

Investment style risk , which is the chance that returns from REIT stocks—which typically are small- or mid-capitalization stocks—will trail returns from the overall stock market. Historically, REIT stocks have performed quite differently from the overall market.

An investment in the Portfolio 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 Portfolio. The bar chart shows how the performance of the Portfolio has varied from one calendar year to another over the periods shown. The table shows how the average annual total returns of the Portfolio compare with those of the Portfolio’s target index and other comparative indexes, which have investment characteristics similar to those of the Portfolio. The REIT Spliced Index reflects performance of the MSCI US REIT Index adjusted to include a 2% cash position (Lipper Money Market Average) through April 30, 2009, and the MSCI US REIT Index thereafter. Effective January 18, 2018, the Portfolio began tracking the MSCI US Investable Market Real Estate 25/50 Index as its target index. The Portfolio’s board of trustees believes that the current index is more closely aligned with the Portfolio’s new investment objective. The Portfolio’s returns are net of its expenses but do not reflect additional fees and expenses that are deducted by the annuity or life insurance program through which you invest. If such fees and expenses were included in the calculation of the Portfolio’s returns, the returns would be lower. Keep in mind that the Portfolio’s past performance does not indicate how the Portfolio will perform in the future. Updated performance information is available on our website for Financial Advisors at advisors.vanguard.com or by calling Vanguard toll-free at 800-522-5555.

Tax Information

The Portfolio normally distributes its net investment income and net realized capital gains, if any, to its shareholders, which are the insurance company separate accounts that sponsor your variable annuity or variable life insurance contract. The tax consequences to you of your investment in the Portfolio depend on the provisions of the annuity or life insurance contract through which you invest. For more information on taxes, please refer to the prospectus of the annuity or life insurance contract through which Portfolio shares are offered.

Payments to Financial Intermediaries

The Portfolio and its investment advisor do not pay financial intermediaries for sales of Portfolio shares.

More on the Portfolio

This prospectus describes the principal risks you would face as an investor in this Portfolio. It is important to keep in mind one of the main axioms of investing: generally, the higher the risk of losing money, the higher the potential reward. The reverse, also, is generally true: the lower the risk, the lower the potential reward. As you consider an investment in any mutual fund, you should take into account your personal tolerance for fluctuations in the securities markets. Look for this symbol throughout the prospectus. It is used to mark detailed information about the more significant risks that you would confront as a Portfolio investor. 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 Portfolio is the right investment for you. We suggest that you keep this prospectus for future reference.

A Note About Vanguard Variable Insurance Fund

The Real Estate Index Portfolio of Vanguard Variable Insurance Fund is a mutual fund used solely as an investment option for annuity or life insurance contracts offered by insurance companies. This means that you cannot purchase shares of the Portfolio directly, but only through a contract offered by an insurance company.

The Real Estate Index Portfolio is separate from other Vanguard mutual funds, even when the Portfolio and a fund have the same investment objective and advisor. The Portfolio’s investment performance will differ from the performance of other Vanguard funds because of differences in the securities held and because of administrative and insurance costs associated with the annuity or life insurance program through which you invest.

Plain Talk About Costs of Investing
 
Costs are an important consideration in choosing a mutual fund. That is because
you, as a contract owner, pay a proportionate share of the costs of operating a
portfolio and any transaction costs incurred when the portfolio buys or sells
securities. These costs can erode a substantial portion of the gross income or the
capital appreciation a portfolio achieves. Even seemingly small differences in
expenses can, over time, have a dramatic effect on a portfolio‘s performance.

 

The following sections explain the principal investment strategies and policies that the Portfolio uses in pursuit of its objective. The Fund‘s board of trustees, which oversees the Portfolio‘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. Under normal circumstances, the Portfolio

6


 

will invest at least 80% of its assets in stocks that make up its target index. This policy may be changed only upon 60 days‘ notice to shareholders.

Market Exposure

The Portfolio invests in stocks of publicly traded equity real estate investment trusts and other real estate-related investments.


The Portfolio 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. The Portfolio‘s target index may, at times, become focused in stocks of a limited number of companies, which could cause the Portfolio to underperform the overall stock market.

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 S&P 500 Index, a widely used barometer of U.S. stock 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.

U.S. Stock Market Average Annual Returns      
(1926– 2016 )        
  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 11.9 10.1 10.3 11.0

 

The table covers all of the rolling 1-, 5-, 10-, and 20-year periods from 1926 through 2016 . You can see, for example, that although the average annual return on common stocks for all of the 5-year periods was 10.1% , 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 Portfolio in particular.

Mutual 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’s important to understand tha t m arket 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

7


 

market capitalization of the Portfolio’s stock holdings as of December 31, 2017, was $xx billion.

Stock funds can also be categorized according to whether the stocks they hold are value or growth stocks or a blend of both. The Real Estate Index Portfolio generally fits into the mid-cap blend category.


The Portfolio is subject to investment style risk, which is the chance that returns from REIT stocks—which typically are small- or mid-capitalization stocks—will trail returns from the overall stock market. Historically, REIT stocks have performed quite differently from the overall market.

Security Selection

The Portfolio uses an indexing investment approach. The Portfolio attempts to replicate the MSCI US Investable Market Real Estate 25/50 Index by investing all, or substantially all, of its assets in the stocks that make up the Index.

Plain Talk About REITs
 
Rather than directly owning properties—which can be costly and difficult to
convert into cash when needed—some investors buy shares in a company that
owns and manages real estate. Such a company is known as a real estate
investment trust, or REIT. Unlike corporations, REITs do not have to pay income
taxes if they meet certain Internal Revenue Code requirements. To qualify, a REIT
must distribute at least 90% of its taxable income to its shareholders and receive
at least 75% of that income from rents, mortgages, and sales of property. REITs
offer investors greater liquidity and diversification than direct ownership of a
handful of properties. REITs also offer the potential for higher income than an
investment in common stocks would provide. As with any investment in real
estate, however, a REIT’s performance depends on specific factors, such as the
company’s ability to find tenants for its properties, to renew leases, and to
finance property purchases and renovations. That said, returns from REITs may
not correspond to returns from direct property ownership.

 

The Portfolio holds each stock contained in the MSCI US Investable Market Real Estate 25/50 Index in approximately the same proportion as its weighting in the Index. For example, if 5% of the MSCI US Investable Market Real Estate 25/50 Index were made up of the stock of a specific REIT, the Portfolio would invest 5% of its assets in that stock.

8


 

Because it invests in stocks of REITs, the Portfolio is subject to several risks in addition to general stock market risk. These risks include:


Industry concentration risk, which is the chance that the stocks of REITs and other real estate-related investments will decline because of adverse developments affecting the real estate industry and real property values. Because the Portfolio concentrates its assets in these stocks, industry concentration risk is high.


Interest rate risk, which is the chance that REIT stock prices overall will decline and that the cost of borrowing for REITs will increase because of rising interest rates. Interest rate risk is high for the Portfolio.

In general, during periods of high interest rates, REITs may lose some of their appeal for investors who may be able to obtain higher yields from other income-producing investments, such as long-term bonds. Higher interest rates also mean that financing for property purchases and improvements are more costly and difficult to obtain.

Plain Talk About Types of REITs
 
An equity REIT generally owns properties directly. Equity REITs typically generate
income from rental and lease payments, and they offer the potential for growth
from property appreciation as well as occasional capital gains from the sale of
property. A mortgage REIT makes loans to commercial real estate developers.
Mortgage REITs earn interest income and are subject to credit risk (i.e., the
chance that a developer will fail to repay a loan). A hybrid REIT holds both
properties and mortgages. The Portfolio invests in equity REITs and other real
estate-related investments.

 

Because of its emphasis on REIT stocks, the Portfolio’s performance may, at times, be linked to the ups and downs of the real estate market. In general, real estate values can be affected by a variety of factors, including, but not limited to, supply and demand for properties, the economic health of the nation as well as different regions, and the strength of specific industries that rent properties. Ultimately, an individual REIT’s performance depends on the types and locations of the properties it owns and on how well the REIT manages its properties. For instance, rental income could decline because of extensive vacancies, increased competition from nearby properties, tenants’ failure to pay rent, regulatory limitations on rents, fluctuations in rental income, variations in market rental rates, or incompetent management. Property values could decrease because of overbuilding in the area, environmental liabilities, uninsured damages caused by natural disasters, a general decline in the neighborhood, losses because of casualty or condemnation, increases in property taxes, or changes in zoning laws. Loss of IRS status as a qualified REIT may also affect

9


 

an individual REIT’s performance. In addition, many real estate issuers, including REITs, utilize leverage (and some may be highly leveraged), which increases investment risk and could adversely affect the issuer’s operations and market value in periods of rising interest rates.

The MSCI US Investable Market Real Estate 25/50 Index is a free-float-adjusted-market-capitalization weighted index . It is made up of stocks of publicly traded equity REITs and real estate-related investments that meet certain criteria. For example, to be included initially in the Index, a REIT must meet a minimum market capitalization threshold and have enough shares and trading volume to be considered liquid. In line with the Index, the Portfolio invests in equity REITs and other real estate-related investments.

The components of the Fund are rebalanced on a xx basis. The Index rebalances as a float-adjusted market-weighted index, and stocks may enter or fall out of the index on a xx basis. New securities are added to and removed from the Index in connection with the xx index rebalance process.

As of December 31, 2017, xx equity REITS were included in the Index. The Index is rebalanced quarterly, except when a merger, acquisition, or similar corporate action dictates same-day rebalancing. On a quarterly basis, current stocks are tested for continued compliance with the guidelines of the Index. A REIT may be removed from the Index because of a decline in market capitalization, because it becomes illiquid, or because of other changes in its status. Securities in the MSCI US Investable Market Real Estate 25/50 Index have differing levels of capitalization. REIT stocks tend to be more volatile than the large-cap stocks that dominate the overall stock market. REIT stocks tend to have a significant amount of dividend income, which can reduce the impact of this volatility. However, the Portfolio is subject to additional risk because of the concentration in the real estate sector. This focus on a single sector may result in more risk than that for a more diversified, multi-sector portfolio.

10


 

Stocks in the MSCI US Investable Market Real Estate 25/50 Index represent a broadly diversified range of property types. The makeup of the Index , as of December 31, 2017, was as follows.

Portfolio Allocation by  
REIT type Percentage of Index
Retail xx %
Specialized xx
Residential xx
Office xx
Health Care xx
Diversified xx
Industrial xx
Hotel & Resort xx

 

Other Investment Policies and Risks

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

The Portfolio may invest in foreign securities to the extent necessary to carry out its investment strategy of holding all, or substantially all, of the stocks that make up the index it tracks.


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

Generally speaking, a derivative is a financial contract whose value is based on the value of a financial asset (such as a stock, a bond, or a currency), a physical asset (such as gold, oil, or wheat), a market index (such as the S&P 500 Index), or a reference rate (such as LIBOR). The Portfolio may invest in derivatives only if the expected risks and rewards of the derivatives are consistent with the investment objective, policies, strategies, and risks of the Portfolio as disclosed in this prospectus. In particular, derivatives will be used only when they may help the advisor to accomplish one or more of the following:

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

11


 

• Obtain economic exposure to a stock, a basket of stocks, or an index when deemed desirable or necessary.

• Add value when these instruments are attractively priced.

The market for many derivatives is, or suddenly can become, illiquid, which may result in significant, rapid, and unpredictable changes in the prices for derivatives. The Portfolio‘s use of a derivative subjects it to the risk of nonperformance by the counterparty, potentially resulting in delayed or partial payment or even nonpayment of amounts due under the derivative contract. The Portfolio attempts to mitigate this risk by requiring the posting of collateral by its counterparty.

The Portfolio‘s derivative investments may include total return swaps or other derivatives.

Plain Talk About Derivatives
 
Derivatives can take many forms. Some forms of derivatives—such as exchange-
traded futures and options on securities, commodities, or indexes—have been
trading on regulated exchanges for decades. These types of derivatives are
standardized contracts that can easily be bought and sold and whose market
values are determined and published daily. Non-exchange-traded derivatives—
such as certain swap agreements and foreign currency exchange forward
contracts—on the other hand, tend to be more specialized or complex and may
be more difficult to accurately value.

 

Cash Management

The Portfolio‘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 Portfolio bears its proportionate share of the expenses of the CMT Fund in which it invests. Vanguard receives no additional revenue from Portfolio assets invested in a Vanguard CMT Fund.

Temporary Investment Measures

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

12


 

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 an investor 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 investors, 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 generally does not disrupt portfolio management or otherwise harm fund investors. 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.

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

You may purchase or sell Portfolio shares through a contract offered by an insurance company. When insurance companies establish omnibus accounts in the Portfolio for their clients, we cannot monitor the individual clients’ trading activity. However, we review trading activity at the omnibus account level, and we look for activity that may indicate potential frequent trading or market-timing. If we detect suspicious trading activity, we will seek the assistance of the insurance company to investigate that trading activity and take appropriate action, including prohibiting additional purchases of Portfolio shares by a client. Insurance companies may apply frequent-trading

13


 

policies that differ from one another. Please read the insurance company contract and program materials carefully to learn of any rules or fees that may apply.

See the accompanying prospectus for the annuity or insurance program through which Portfolio shares are offered for further details on transaction policies.

The Portfolio, 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

A mutual fund’s turnover rate is a measure of its trading activity. Generally, an index fund sells securities in response to redemption requests or to changes in the composition of its target index. The Portfolio may sell securities regardless of how long they have been held. The historical turnover rates for the Portfolio can be found in the Financial Highlights section of this prospectus. A turnover rate of 100% for example, would mean that a Portfolio had sold and replaced securities valued at 100% of its net assets within a one-year period.

Plain Talk About Turnover Rate
 
Before investing in a mutual fund, you should review its turnover rate. This rate
gives an indication of how transaction costs, which are not included in the fund’s
expense ratio, could affect the fund’s future returns. In general, the greater the
volume of buying and selling by the fund, the greater the impact that brokerage
commissions and other transaction costs will have on its return. Also, funds with
high turnover rates may be more likely to generate capital gains, including short-
term capital gains, that must be distributed to shareholders and will be taxable to
shareholders investing through a taxable account.

 

The Portfolio and Vanguard

Vanguard Variable Insurance Fund is a member of The Vanguard Group, a family of more than 200 funds holding assets of approximately $xx 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

14


 

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 Portfolio through its Equity Index Group . As of December 31, 2017, Vanguard managed approximately $xx trillion in assets. Vanguard provides investment advisory services to the Portfolio on at at-cost basis, subject to the supervision and oversight of the trustees and officers of the Portfolio.

For the fiscal year ended December 31, 2017, the Portfolio’s advisory expenses represented an effective annual rate of 0.xx% of the Portfolio’s average net assets.

Under the terms of an SEC exemption, the Portfolio’s board of trustees may, without prior approval from shareholders, change the terms of an advisory agreement with a third-party investment advisor or hire a new third-party investment advisor—either as a replacement for an existing advisor or as an additional advisor. Any significant change in a Portfolio’s advisory arrangements will be communicated to shareholders in writing. As the Portfolio’s sponsor and overall manager, Vanguard may provide additional investment advisory services to the Portfolio, on an at-cost basis, at any time. Vanguard may also recommend to the board of trustees that an advisor be hired, terminated, or replaced or that the terms of an existing advisory agreement be revised. The Portfolio has filed an application seeking a similar SEC exemption with respect to investment advisors that are wholly-owned subsidiaries of Vanguard. If granted, the Portfolio may rely on the new SEC relief.

For a discussion of why the board of trustees approved the Portfolio’s investment advisory arrangement, see the Vanguard Variable Insurance Fund’s most recent semiannual report to shareholders covering the fiscal period ended June 30.

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

Walter Nejman , Portfolio Manager at Vanguard. He has been with Vanguard since 2005, has worked in investment management since 2008, and has co-managed the Portfolio since 2016. Education: B.A., Arcadia University; M.B.A., Villanova University.

Gerard C. O’Reilly , Principal of Vanguard. He has been with Vanguard since 1992, has managed investment portfolios since 1994, and has managed the Portfolio since its inception in 1999 (co-managed since 2016) . Education: B.S., Villanova University.

The Fund’s Statement of Additional Information provides information about each portfolio manager’s compensation, other accounts under management, and ownership of shares of the Portfolio.

Taxes

The Portfolio normally distributes its net investment income and net realized short-term or long-term capital gains, if any, to its shareholders, which are the insurance company separate accounts that fund your variable annuity or variable life insurance contract. The tax consequences to you of your investment in the Portfolio depend on the provisions of the annuity or life insurance contract through which you invest; please refer to the prospectus of such contract for more information.

The Portfolio intends to operate in such a manner that a separate account investing only in Portfolio shares will result in the variable annuity and variable life insurance contracts supported by that account receiving favorable tax treatment. This favorable treatment means that you generally will not be taxed on Portfolio distributions or proceeds on dispositions of Portfolio shares received by the separate account funding your contract. In order to qualify for this favorable treatment, the insurance company separate accounts that invest in the Portfolio must satisfy certain requirements. If a Portfolio funding your contract does not meet such requirements, your contract could lose its favorable tax treatment, and income and gain allocable to your contract could be taxable to you. Also, if the IRS were to determine that contract holders have an impermissible level of control over the investments funding their contracts, your contract could lose its favorable tax treatment and income and gain allocable to your contract could be taxable currently to you. Please see the Vanguard Variable Insurance Fund’s Statement of Additional Information for more information.

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 (NYSE), generally 4 p.m., Eastern time. The NAV per share is computed by dividing the total assets, minus liabilities, of the Portfolio by the number of Portfolio shares outstanding. On

16


 

U.S. holidays or other days when the NYSE is closed, the NAV is not calculated, and the Portfolio does not sell or redeem shares. However, on those days the value of the Portfolio’s assets may be affected to the extent that the Portfolio holds securities that change in value on those days (such as foreign securities that trade on foreign markets that are open).

Stocks held by a Vanguard portfolio are valued at their market value when reliable market quotations are readily available from the principal exchange or market on which they are traded. Such securities are generally valued at their official closing price, the last reported sales price, or if there were no sales that day, the mean between the closing bid and asking prices. When a portfolio determines that pricing-service information or market quotations either are not readily available or do not accurately reflect the value of a security, the security is priced at its fair value (the amount that the owner might reasonably expect to receive upon the current sale of the security).

The values of any foreign securities held by a portfolio are converted into U.S. dollars using an exchange rate obtained from an independent third party as of the close of regular trading on the NYSE. The values of any mutual fund shares, including institutional money market fund shares, held by a portfolio are based on the NAVs of the shares. The values of any ETF shares or closed-end fund shares held by a portfolio are based on the market value of the shares.

A portfolio also will use fair-value pricing if the value of a security it holds has been materially affected by events occurring before the portfolio’s pricing time but after the close of the principal exchange or market on which the security is traded. This most commonly occurs with foreign securities, which may trade on foreign exchanges that close many hours before the portfolio’s pricing 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 exceed a specified threshold or that are otherwise 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 portfolio’s pricing time or a security does not trade in the course of a day and (2) the portfolio holds enough of the security that its price could affect the portfolio’s NAV.

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 portfolio to calculate its NAV may differ from quoted or published prices for the same securities.

The Portfolio’s NAV is used to determine the unit value for the annuity or life insurance program through which you invest. For more information on unit values, please refer to the accompanying prospectus of the insurance company that offers your annuity or life insurance program.

Financial Highlights

The following financial highlights table is intended to help you understand the Portfolio’s financial performance for the periods shown, and certain information reflects financial results for a single Portfolio share. The total returns in the table represent the rate that an investor would have earned or lost each period on an investment in the Portfolio (assuming reinvestment of all distributions). This information has been obtained from the financial statements audited by xx, an independent registered public accounting firm, whose report—along with the Portfolio’s financial statements—is included in Vanguard Variable Insurance 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.

Yields and total returns presented for the Portfolio are net of the Portfolio’s operating expenses, but do not take into account charges and expenses attributable to the annuity or life insurance program through which you invest. The expenses of the annuity or life insurance program reduce the returns and yields you ultimately receive, so you should bear those expenses in mind when evaluating the performance of the Portfolio and when comparing the yields and returns of the Portfolio with those of other mutual funds.

Plain Talk About How to Read the Financial Highlights Table
 
The Portfolio began fiscal year 2017 with a net asset value (share price) of $XXXX
per share. During the year, the Portfolio earned $0.XXX per share from
investment income (interest and dividends) and $XX.XX per share from
investments that had appreciated in value or that were sold for higher prices than
the Portfolio paid for them.
 
Shareholders received $0.XXX per share in the form of dividend and capital gains
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 $XXX, reflecting earnings of $XXX per
share and distributions of $0.XXX per share. This was an increase of $XXX per
share (from $XXXX at the beginning of the year to $XXX at the end of the year).
For a shareholder who reinvested the distributions in the purchase of more
shares, the total return was XXX% for the year.
 
As of December 31, 2017, the Portfolio had approximately $XXX million in net
assets. For the year, its expense ratio was 0.XX% ($XXX per $1,000 of net
assets), and its net investment income amounted to 0.XX% of its average net
assets. The Portfolio sold and replaced securities valued at XX% of its net assets.

General Information

This Portfolio of Vanguard Variable Insurance Fund offers its shares to insurance companies to fund both annuity and life insurance contracts. Because of differences in tax treatment or other considerations, the best interests of various contract owners participating in the Portfolio might at some time be in conflict. The Fund’s board of trustees will monitor for any material conflicts and determine what action, if any, should be taken.

If the board of trustees determines that continued offering of shares would be detrimental to the best interests of the Portfolio’s shareholders, the Portfolio may suspend the offering of shares for a period of time. If the board of trustees determines that a specific purchase acceptance would be detrimental to the best interests of the Portfolio’s shareholders (for example, because of the size of the purchase request or a history of frequent trading by the investor), the Portfolio may reject such a purchase request.

If you wish to redeem money from the Portfolio, please refer to the instructions provided in the accompanying prospectus for the annuity or life insurance program. Shares of the Portfolio may be redeemed on any business day. The redemption price of shares will be at the next-determined net asset value per share. Redemption proceeds will be wired to the administrator generally on the day following receipt of the redemption request, but no later than seven calendar days. Contract owners will receive their redemption checks from the administrator.

Under normal circumstances, the Portfolio typically expects to meet redemptions with other positive cash flows. When this is not an option, the Portfolio seeks to maintain its risk exposure by selling a cross section of the Portfolio‘s holdings to meet redemptions, while also factoring in transaction costs. Additionally, the Portfolio may work with the insurance companies through which contract owners participate in the Portfolio to implement redemptions in a manner that is least disruptive to the portfolio.

Under certain circumstances, including under stressed market conditions, there are additional tools that the Portfolio may use in order to meet redemptions, including advancing the settlement of market trades with counterparties to match investor redemption payments or delaying settlement of an investor’s transaction to match trade settlement within regulatory requirements. The Portfolio may also suspend payment of redemption proceeds for up to seven days. Additionally, under these unusual circumstances, the Portfolio may borrow money (subject to certain regulatory conditions and, if available, under board-approved procedures) through an interfund lending facility or through a bank line-of-credit, including a joint committed credit facility, in order to meet redemption requests.

20


 

The Portfolio may suspend the redemption right or postpone payment at times when the New York Stock Exchange is closed or during any emergency circumstances, as determined by the Securities and Exchange Commission.

The exchange privilege (your ability to redeem shares from one Portfolio to purchase shares of another Portfolio) may be available to you through your contract. Although we make every effort to maintain the exchange privilege, Vanguard reserves the right to revise or terminate this privilege, limit the amount of an exchange, or reject any exchange, at any time, without notice.

If the board of trustees determines that it would be detrimental to the best interests of the Portfolio’s remaining shareholders to make payment in cash, the Portfolio may pay redemption proceeds, in whole or in part, by an in-kind distribution of readily marketable securities.

For certain categories of investors, the Portfolio has authorized one or more brokers to accept on its behalf purchase and redemption orders. The brokers are authorized to designate other intermediaries to accept purchase and redemption orders on the Portfolio’s behalf. The Portfolio will be deemed to have received a purchase or redemption order when an authorized broker, or a broker’s authorized designee, accepts the order in accordance with the Portfolio’s instructions. In most cases, for these categories of investors, a contract owner’s properly transmitted order will be priced at the Portfolio’s next-determined NAV after the order is accepted by the authorized broker or the broker’s designee. The contract owner should review the authorized broker’s policies relating to trading in the Vanguard funds.

Please consult the Vanguard Variable Insurance Fund’s Statement of Additional Information or our website for a description of the policies and procedures that govern disclosure of the Fund’s portfolio holdings.

Inception Date. The date on which the assets of a portfolio are first invested in accordance with the portfolio’s investment objective. For portfolios 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.”

Joint Committed Credit Facility. The Portfolio participates, along with other funds managed by Vanguard, in a committed credit facility provided by a syndicate of lenders pursuant to a credit agreement that may be renewed annually; each fund is individually liable for its borrowings, if any, under the credit facility. The amount and terms of the committed credit facility are subject to approval by the fund’s board of trustees and renegotiation with the lender syndicate on an annual basis.

Liquidity. The degree of a security’s marketability (i.e., how quickly the security can be sold at a fair price and converted to cash).

Median Market Capitalization. An indicator of the size of companies in which a portfolio invests; the midpoint of market capitalization (market price x shares outstanding) of a portfolio’s stocks, weighted by the proportion of the portfolio’s assets invested in each stock.

In the rare event the NYSE experiences unanticipated trade disruptions and is unavailable at the close of the trading day, NAVs will be calculated as of the close of regular trading on the Nasdaq (or another alternate exchange if the Nasdaq is unavailable, as determined at Vanguard’s discretion) , generally 4 p.m., Eastern time.

Real Estate Investment Trust (REIT). A company that owns and manages a group of properties, mortgages, or both.

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

Organization

The Trust was organized as a Maryland corporation in 1989 before becoming a Pennsylvania business trust later in 1989, and was reorganized as a Delaware statutory trust in 1998. The Trust is registered with the United States Securities and Exchange Commission (SEC) under the Investment Company Act of 1940 (the 1940 Act) as an open-end management investment company. All Portfolios within the Trust are classified as diversified within the meaning of the 1940 Act.

Each Portfolio offers its shares to insurance companies that sponsor both annuity and life insurance contracts. An insurance company might offer some, but not necessarily all, of the Portfolios.

Service Providers

Custodians. The Bank of New York Mellon, 225 Liberty Street, New York, NY 10286 (for the Capital Growth, Growth, Money Market, and Short-Term Investment-Grade Portfolios); Brown Brothers Harriman & Co., 50 Post Office Square, Boston, MA 02110-1548 (for the Conservative Allocation, Equity Income, International, Moderate Allocation, and Total Stock Market Index Portfolios); State Street Bank and Trust Company, One Lincoln Street, Boston, MA 02111 (for the Balanced, Diversified Value, Equity Index, High Yield Bond, Mid-Cap Index, Real Estate Index, and Small Company Growth Portfolios); and JPMorgan Chase Bank, 383 Madison Avenue, New York, NY 10179 (for the Global Bond Index, Total Bond Market Index, and Total International Stock Market Index Portfolios), serve as the Portfolios’ custodians. The custodians are responsible for maintaining the Portfolios’ assets, keeping all necessary accounts and records of Portfolio assets, and appointing any foreign subcustodians or foreign securities depositories.

Independent Registered Public Accounting Firm. PricewaterhouseCoopers LLP, Two Commerce Square, Suite 1800, 2001 Market Street, Philadelphia, PA 19103-7042, serves as the Portfolios‘ independent registered public accounting firm. The independent registered public accounting firm audits the Portfolios‘ annual financial statements and provides other related services.

Transfer and Dividend-Paying Agent. The Portfolios‘ transfer agent and dividend-paying agent is Vanguard, P.O. Box 2600, Valley Forge, PA 19482.

Characteristics of the Fund‘s Shares

Restrictions on Holding or Disposing of Shares. There are no restrictions on the right of shareholders to retain or dispose of a Portfolio’s shares, other than those described in the Portfolio’s current prospectus and elsewhere in this Statement of Additional Information. Each Portfolio or class may be terminated by reorganization into another mutual fund or class or by liquidation and distribution of the assets of the Portfolio or class. Unless terminated by reorganization or liquidation, each Portfolio and share class will continue indefinitely.

Shareholder Liability. The Trust is organized under Delaware law, which provides that shareholders of a statutory trust are entitled to the same limitations of personal liability as shareholders of a corporation organized under Delaware law. This means that a shareholder of a Portfolio generally will not be personally liable for payment of the Portfolio’s debts. Some state courts, however, may not apply Delaware law on this point. We believe that the possibility of such a situation arising is remote.

Dividend Rights. The shareholders of each class of a Portfolio are entitled to receive any dividends or other distributions declared by the Portfolio for each such class. No shares of a Portfolio have priority or preference over any other shares of the Portfolio with respect to distributions. Distributions will be made from the assets of the Portfolio, and will be paid ratably to all shareholders of a particular class according to the number of shares of the class held by shareholders on the record date. The amount of dividends per share may vary between separate share classes of the Portfolio based upon differences in the net asset values of the different classes and differences in the way that expenses are allocated between share classes pursuant to a multiple class plan approved by the Fund’s board of trustees.

Voting Rights. Shareholders are entitled to vote on a matter if (1) the matter concerns an amendment to the Declaration of Trust that would adversely affect to a material degree the rights and preferences of the shares of a Portfolio or class; (2) the trustees determine that it is necessary or desirable to obtain a shareholder vote; (3) a merger or consolidation, share conversion, share exchange, or sale of assets is proposed and a shareholder vote is required by the 1940 Act to approve the transaction; or (4) a shareholder vote is required under the 1940 Act. The 1940 Act requires a shareholder vote under various circumstances, including to elect or remove trustees upon the written request of shareholders representing 10% or more of a Portfolio’s net assets, to change any fundamental policy of a Portfolio, and to enter into

B-2


 

certain merger transactions. Unless otherwise required by applicable law, shareholders of each Portfolio receive one vote for each dollar of net asset value owned on the record date, and a fractional vote for each fractional dollar of net asset value owned on the record date. However, only the shares of the Portfolio or class affected by a particular matter are entitled to vote on that matter. Voting rights are noncumulative and cannot be modified without a majority vote by the shareholders.

Liquidation Rights. In the event that a Portfolio is liquidated, shareholders will be entitled to receive a pro rata share of the Portfolio’s net assets. Shareholders may receive cash, securities, or a combination of the two.

Preemptive Rights. There are no preemptive rights associated with the Portfolios’ shares.

Conversion Rights . There are no conversion rights associated with the Portfolios’ shares.

Redemption Provisions . Each Portfolio’s redemption provisions are described in the current annuity or life insurance program prospectus and elsewhere in this Statement of Additional Information.

Sinking Fund Provisions . The Portfolios have no sinking fund provisions.

Calls or Assessment. Each Portfolio’s shares, when issued, are fully paid and non-assessable.

Tax Status of the Portfolios

Each Portfolio expects to qualify each year for treatment as a “regulated investment company” under Subchapter M of the Internal Revenue Code of 1986, as amended (the IRC). This special tax status means that the Portfolios will not be liable for federal tax on income and capital gains distributed to shareholders. In order to preserve its tax status, each Portfolio must comply with certain income and asset diversification requirements. If a Portfolio fails to meet these requirements in any taxable year, the Portfolio will, in some cases, be able to cure such failure, including by paying a portfolio-level tax, paying interest, making additional distributions, or disposing of certain assets. If the Portfolio is ineligible to or otherwise does not cure such failure for any year, it will be subject to tax on its taxable income at corporate rates . In addition, the Portfolio could be required to recognize unrealized gains, pay substantial taxes and interest, and make substantial distributions before regaining its tax status as a regulated investment company .

Further, each Portfolio intends to comply with the separate asset diversification requirements imposed by Section 817(h) of the IRC on certain insurance company separate accounts. If a Portfolio were to fail to qualify as a regulated investment company or the Section 817(h) diversification test , each insurance company’s separate account invested in the Portfolio would fail to satisfy the account’s separate diversification requirements under the IRC, with the result that income and gain allocable to the variable annuity and variable life insurance contracts supported by that account could be taxable to contract holders currently. Dividends received and distributed by a Portfolio on shares of stock of domestic corporations (except REITs) may be eligible for the dividends-received deduction applicable to corporate shareholders. Insurance companies investing in the Portfolios through one or more separate accounts must satisfy certain requirements in order to claim the deduction. Capital gains distributed by the Portfolios are not eligible for the dividends-received deduction .

For more information on the tax treatment of the Portfolios and its insurance company separate account shareholders, see “ Tax Matters—Federal Tax Discussion Applicable to Variable Annuity and Variable Life Insurance Contracts .”

FUNDAMENTAL POLICIES

Each Portfolio is subject to the following fundamental investment policies, which cannot be changed in any material way without the approval of the holders of a majority of the affected Portfolio’s shares. For these purposes, a “majority” of shares means shares representing the lesser of (1) 67% or more of the Portfolio’s net assets voted, so long as shares representing more than 50% of the Portfolio’s net assets are present or represented by proxy or (2) more than 50% of the Portfolio’s net assets.

Borrowing . Each Portfolio may borrow money only as permitted by the 1940 Act or other governing statute, by the Rules thereunder, or by the SEC or other regulatory agency with authority over the Portfolio.

Commodities . Each Portfolio may invest in commodities only as permitted by the 1940 Act or other governing statute, by the Rules thereunder, or by the SEC or other regulatory agency with authority over the Portfolio.

Diversification . With respect to 75% of its total assets, each Portfolio (other than the Conservative Allocation, Global Bond Index, Moderate Allocation, Total International Stock Market Index, and Total Stock Market Index Portfolios) may

B-3


 

not: (1) purchase more than 10% of the outstanding voting securities of any one issuer; or (2) purchase securities of any issuer if, as a result, more than 5% of the Portfolio’s total assets would be invested in that issuer’s securities. This limitation does not apply to obligations of the U. S. government or its agencies or instrumentalities. Additionally, each Portfolio (except the Conservative Allocation, Global Bond Index, Moderate Allocation, Total International Stock Market Index, and Total Stock Market Index Portfolios) will limit the aggregate value of its holdings of a single issuer (other than U.S. government securities, as defined in the IRC), to a maximum of 25% of the Portfolio’s total assets as of the end of each quarter of the taxable year.

The Total Stock Market Index Portfolio will limit the aggregate value of its holdings (other than U.S. government securities, cash, and cash items, as defined under subchapter M of the IRC, and securities of other regulated investment companies), for each holding that exceeds 5% of the Portfolio’s total assets or 10% of the issuer’s outstanding voting securities, to an aggregate of 50% of the Portfolio’s total assets as of the end of each quarter of the taxable year. Additionally, the Portfolio will limit the aggregate value of its holdings of a single issuer (other than U.S. government securities, as defined in the IRC, or the securities of other regulated investment companies) to a maximum of 25% of the Portfolio’s total assets as of the end of each quarter of the taxable year.

Industry Concentration . Each Portfolio (other than those indicated in the following exceptions) will not concentrate its investments in the securities of issuers whose principal business activities are in the same industry.

The Money Market Portfolio will concentrate its assets in the securities of issuers whose principal business activities are in the financial services industry. For the purposes of this policy, the financial services industry is deemed to include the group of industries within the financial services sector. In addition, the Portfolio reserves the right to concentrate its investments in government securities, as defined in the 1940 Act.

The Real Estate Index Portfolio will concentrate its investments in the securities of issuers whose principal business activities are in the real estate industry, as defined in the prospectus.

For the Equity Index, Global Bond Index, Mid-Cap Index, Total Bond Market Index, Total International Stock Market Index, and Total Stock Market Index Portfolios: Each Portfolio will not concentrate its investments in the securities of issuers whose principal business activities are in the same industry, except as may be necessary to approximate the composition of its target index.

Investment Objective . The investment objective of each Portfolio (except the Global Bond Index and Total International Stock Market Index Portfolios) may not be materially changed without the approval of a majority of such Portfolio’s shareholders.

Loans . Each Portfolio may make loans to another person only as permitted by the 1940 Act or other governing statute, by the Rules thereunder, or by the SEC or other regulatory agency with authority over the Portfolio.

Real Estate . Each Portfolio may not invest directly in real estate unless it is acquired as a result of ownership of securities or other instruments. This restriction shall not prevent the Portfolio from investing in securities or other instruments (1) issued by companies that invest, deal, or otherwise engage in transactions in real estate or (2) backed or secured by real estate or interests in real estate.

Senior Securities . Each Portfolio may not issue senior securities except as permitted by the 1940 Act or other governing statute, by the Rules thereunder, or by the SEC or other regulatory agency with authority over the Portfolio.

Underwriting . Each Portfolio may not act as an underwriter of another issuer’s securities, except to the extent that the Portfolio may be deemed to be an underwriter within the meaning of the Securities Act of 1933 (the 1933 Act), in connection with the purchase and sale of portfolio securities.

Compliance with the fundamental policies previously described is generally measured at the time the securities are purchased. Unless otherwise required by the 1940 Act (as is the case with borrowing), if a percentage restriction is adhered to at the time the investment is made, a later change in percentage resulting from a change in the market value of assets will not constitute a violation of such restriction. All fundamental policies must comply with applicable regulatory requirements. For more details, see Investment Strategies, Risks, and Nonfundamental Policies .

None of these policies prevents the Fund from having an ownership interest in Vanguard. As a part owner of Vanguard, the Fund may own securities issued by Vanguard, make loans to Vanguard, and contribute to Vanguard’s costs or other financial requirements. See Management of the Fund for more information.

INVESTMENT STRATEGIES, RISKS, AND NONFUNDAMENTAL POLICIES

Some of the investment strategies and policies described on the following pages and in each Portfolio’s prospectus set forth percentage limitations on a Portfolio’s investment in, or holdings of, certain securities or other assets. Unless otherwise required by law, compliance with these strategies and policies will be determined immediately after the acquisition of such securities or assets by the Portfolio. Subsequent changes in values, net assets, or other circumstances will not be considered when determining whether the investment complies with the Portfolio’s investment strategies and policies.

The following investment strategies, risks, and policies supplement each Portfolio’s investment strategies, risks, and policies set forth in the prospectus. With respect to the different investments discussed as follows, a Portfolio may acquire such investments to the extent consistent with its investment strategies and policies. The Conservative Allocation, Global Bond Index, Moderate Allocation, Total International Stock Market Index, and Total Stock Market Index Portfolios (the Fund-of-Fund Portfolios) are indirectly exposed to the investment strategies and policies of the underlying Vanguard funds in which they invest and are therefore subject to all risks associated with the investment strategies and policies of the underlying Vanguard funds. The investment strategies and policies and associated risks detailed in this section also include those to which the Fund-of-Fund Portfolios indirectly may be exposed through their investment in the underlying Vanguard funds.

Asset-Backed Securities . Asset-backed securities represent a participation in, or are secured by and payable from, pools of underlying assets such as debt securities, bank loans, motor vehicle installment sales contracts, installment loan contracts, leases of various types of real and personal property, receivables from revolving credit (i.e., credit card) agreements, and other categories of receivables. These underlying assets are securitized through the use of trusts and special purpose entities. Payment of interest and repayment of principal on asset-backed securities may be largely dependent upon the cash flows generated by the underlying assets backing the securities and, in certain cases, may be supported by letters of credit, surety bonds, or other credit enhancements. The rate of principal payments on asset-backed securities is related to the rate of principal payments, including prepayments, on the underlying assets. The credit quality of asset-backed securities depends primarily on the quality of the underlying assets, the level of credit support, if any, provided for the securities, and the credit quality of the credit-support provider, if any. The value of asset-backed securities may be affected by the various factors described above and other factors, such as changes in interest rates, the availability of information concerning the pool and its structure, the creditworthiness of the servicing agent for the pool, the originator of the underlying assets, or the entities providing the credit enhancement.

Asset-backed securities are often subject to more rapid repayment than their stated maturity date would indicate, as a result of the pass-through of prepayments of principal on the underlying assets. Prepayments of principal by borrowers or foreclosure or other enforcement action by creditors shortens the term of the underlying assets. The occurrence of prepayments is a function of several factors, such as the level of interest rates, the general economic conditions, the location and age of the underlying obligations, and other social and demographic conditions. A fund’s ability to maintain positions in asset-backed securities is affected by the reductions in the principal amount of the underlying assets because of prepayments. A fund’s ability to reinvest prepayments of principal (as well as interest and other distributions and sale proceeds) at a comparable yield is subject to generally prevailing interest rates at that time. The value of asset-backed securities varies with changes in market interest rates generally and the differentials in yields among various kinds of U.S. government securities, mortgage-backed securities, and asset-backed securities. In periods of rising interest rates, the rate of prepayment tends to decrease, thereby lengthening the average life of the underlying securities. Conversely, in periods of falling interest rates, the rate of prepayment tends to increase, thereby shortening the average life of such assets. Because prepayments of principal generally occur when interest rates are declining, an investor, such as a fund, generally has to reinvest the proceeds of such prepayments at lower interest rates than those at which the assets were previously invested. Therefore, asset-backed securities have less potential for capital appreciation in periods of falling interest rates than other income-bearing securities of comparable maturity.

Because asset-backed securities generally do not have the benefit of a security interest in the underlying assets that is comparable to a mortgage, asset-backed securities present certain additional risks that are not present with mortgage-backed securities. For example, revolving credit receivables are generally unsecured and the debtors on such receivables are entitled to the protection of a number of state and federal consumer credit laws, many of which give debtors the right to set off certain amounts owed, thereby reducing the balance due. Automobile receivables generally are secured, but by automobiles rather than by real property. Most issuers of automobile receivables permit loan servicers to retain

B-5


 

possession of the underlying assets. If the servicer of a pool of underlying assets sells them to another party, there is the risk that the purchaser could acquire an interest superior to that of holders of the asset-backed securities. In addition, because of the large number of vehicles involved in a typical issue of asset-backed securities and technical requirements under state law, the trustee for the holders of the automobile receivables may not have a proper security interest in the automobiles. Therefore, there is the possibility that recoveries on repossessed collateral may not be available to support payments on these securities. Asset-backed securities have been, and may continue to be, subject to greater liquidity risks because of the deterioration of worldwide economic and liquidity conditions that became acute in 2008. In addition, government actions and proposals that affect the terms of underlying home and consumer loans, thereby changing demand for products financed by those loans, as well as the inability of borrowers to refinance existing loans, have had and may continue to have a negative effect on the valuation and liquidity of asset-backed securities.

Borrowing . A fund’s ability to borrow money is limited by its investment policies and limitations; by the 1940 Act; and by applicable exemptions, no-action letters, interpretations, and other pronouncements issued from time to time by the SEC and its staff or any other regulatory authority with jurisdiction. Under the 1940 Act, a fund is required to maintain continuous asset coverage (that is, total assets including borrowings, less liabilities exclusive of borrowings) of 300% of the amount borrowed, with an exception for borrowings not in excess of 5% of the fund’s total assets made for temporary or emergency purposes. Any borrowings for temporary purposes in excess of 5% of the fund’s total assets must maintain continuous asset coverage. If the 300% asset coverage should decline as a result of market fluctuations or for other reasons, a fund may be required to sell some of its portfolio holdings within three days (excluding Sundays and holidays) to reduce the debt and restore the 300% asset coverage, even though it may be disadvantageous from an investment standpoint to sell securities at that time.

Borrowing will tend to exaggerate the effect on net asset value of any increase or decrease in the market value of a fund’s portfolio. Money borrowed will be subject to interest costs that may or may not be recovered by earnings on the securities purchased with the proceeds of such borrowing. A fund also may be required to maintain minimum average balances in connection with a borrowing or to pay a commitment or other fee to maintain a line of credit; either of these requirements would increase the cost of borrowing over the stated interest rate.

The SEC takes the position that transactions that have a leveraging effect on the capital structure of a fund or are economically equivalent to borrowing can be viewed as constituting a form of borrowing by the fund for purposes of the 1940 Act. These transactions can include entering into reverse repurchase agreements; engaging in mortgage-dollar-roll transactions; selling securities short (other than short sales “against-the-box”); buying and selling certain derivatives (such as futures contracts); selling (or writing) put and call options; engaging in sale-buybacks; entering into firm-commitment and standby-commitment agreements; engaging in when-issued, delayed-delivery, or forward-commitment transactions; and participating in other similar trading practices. (Additional discussion about a number of these transactions can be found on the following pages.) A borrowing transaction will not be considered to constitute the issuance, by a fund, of a “senior security,” as that term is defined in Section 18(g) of the 1940 Act, and therefore such transaction will not be subject to the 300% asset coverage requirement otherwise applicable to borrowings by a fund, if the fund maintains an offsetting financial position; segregates liquid assets (with such liquidity determined by the advisor in accordance with procedures established by the board of trustees) equal (as determined on a daily mark-to-market basis) in value to the fund’s potential economic exposure under the borrowing transaction; or otherwise “covers” the transaction in accordance with applicable SEC guidance (collectively, “covers” the transaction). A fund may have to buy or sell a security at a disadvantageous time or price in order to cover a borrowing transaction. In addition, segregated assets may not be available to satisfy redemptions or to fulfill other obligations.

Common Stock . Common stock represents an equity or ownership interest in an issuer. Common stock typically entitles the owner to vote on the election of directors and other important matters, as well as to receive dividends on such stock. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of bonds, other debt holders, and owners of preferred stock take precedence over the claims of those who own common stock.

Convertible Securities . Convertible securities are hybrid securities that combine the investment characteristics of bonds and common stocks. Convertible securities typically consist of debt securities or preferred stock that may be converted (on a voluntary or mandatory basis) within a specified period of time (normally for the entire life of the security) into a certain amount of common stock or other equity security of the same or a different issuer at a predetermined price. Convertible securities also include debt securities with warrants or common stock attached and derivatives combining the features of debt securities and equity securities. Other convertible securities with features and risks not specifically referred to herein may become available in the future. Convertible securities involve risks similar to

B-6


 

those of both fixed income and equity securities. In a corporation’s capital structure, convertible securities are senior to common stock but are usually subordinated to senior debt obligations of the issuer.

The market value of a convertible security is a function of its “investment value” and its “conversion value.” A security’s “investment value” represents the value of the security without its conversion feature (i.e., a nonconvertible debt security). The investment value may be determined by reference to its credit quality and the current value of its yield to maturity or probable call date. At any given time, investment value is dependent upon such factors as the general level of interest rates, the yield of similar nonconvertible securities, the financial strength of the issuer, and the seniority of the security in the issuer’s capital structure. A security’s “conversion value” is determined by multiplying the number of shares the holder is entitled to receive upon conversion or exchange by the current price of the underlying security. If the conversion value of a convertible security is significantly below its investment value, the convertible security will trade like nonconvertible debt or preferred stock and its market value will not be influenced greatly by fluctuations in the market price of the underlying security. In that circumstance, the convertible security takes on the characteristics of a bond, and its price moves in the opposite direction from interest rates. Conversely, if the conversion value of a convertible security is near or above its investment value, the market value of the convertible security will be more heavily influenced by fluctuations in the market price of the underlying security. In that case, the convertible security’s price may be as volatile as that of common stock. Because both interest rates and market movements can influence its value, a convertible security generally is not as sensitive to interest rates as a similar debt security, nor is it as sensitive to changes in share price as its underlying equity security. Convertible securities are often rated below investment-grade or are not rated, and they are generally subject to a high degree of credit risk.

Although all markets are prone to change over time, the generally high rate at which convertible securities are retired (through mandatory or scheduled conversions by issuers or through voluntary redemptions by holders) and replaced with newly issued convertible securities may cause the convertible securities market to change more rapidly than other markets. For example, a concentration of available convertible securities in a few economic sectors could elevate the sensitivity of the convertible securities market to the volatility of the equity markets and to the specific risks of those sectors. Moreover, convertible securities with innovative structures, such as mandatory-conversion securities and equity-linked securities, have increased the sensitivity of the convertible securities market to the volatility of the equity markets and to the special risks of those innovations, which may include risks different from, and possibly greater than, those associated with traditional convertible securities. A convertible security may be subject to redemption at the option of the issuer at a price set in the governing instrument of the convertible security. If a convertible security held by a fund is subject to such redemption option and is called for redemption, the fund must allow the issuer to redeem the security, convert it into the underlying common stock, or sell the security to a third party.

Cybersecurity Risks . The increased use of technology to conduct business could subject a fund and its third-party service providers (including, but not limited to, investment advisors and custodians) to risks associated with cybersecurity. In general, a cybersecurity incident can occur as a result of a deliberate attack designed to gain unauthorized access to digital systems. If the attack is successful, an unauthorized person or persons could misappropriate assets or sensitive information, corrupt data, or cause operational disruption. A cybersecurity incident could also occur unintentionally if, for example, an authorized person inadvertently released proprietary or confidential information. Vanguard has developed robust technological safeguards and business continuity plans to prevent, or reduce the impact of, potential cybersecurity incidents. Additionally, Vanguard has a process for assessing the information security and/or cybersecurity programs implemented by a fund’s third-party service providers, which helps minimize the risk of potential incidents. Despite these measures, a cybersecurity incident still has the potential to disrupt business operations, which could negatively impact a fund and/or its shareholders. Some examples of negative impacts that could occur as a result of a cybersecurity incident include, but are not limited to, the following: a fund may be unable to calculate its net asset value (NAV), a fund’s shareholders may be unable to transact business, a fund may be unable to process transactions on behalf of its shareholders, or a fund may be unable to safeguard its data or the personal information of its shareholders.

Debt Securities . A debt security, sometimes called a fixed income security, consists of a certificate or other evidence of a debt (secured or unsecured) on which the issuing company or governmental body promises to pay the holder thereof a fixed, variable, or floating rate of interest for a specified length of time and to repay the debt on the specified maturity date. Some debt securities, such as zero-coupon bonds, do not make regular interest payments but are issued at a discount to their principal or maturity value. Debt securities include a variety of fixed income obligations, including, but not limited to, corporate bonds, government securities, municipal securities, convertible securities, mortgage-backed

B-7


 

securities, and asset-backed securities. Debt securities include investment-grade securities, non-investment-grade securities, and unrated securities. Debt securities are subject to a variety of risks, such as interest rate risk, income risk, call risk, prepayment risk, extension risk, inflation risk, credit risk, liquidity risk, and (in the case of foreign securities) country risk and currency risk. The reorganization of an issuer under the federal bankruptcy laws may result in the issuer’s debt securities being cancelled without repayment, repaid only in part, or repaid in part or in whole through an exchange thereof for any combination of cash, debt securities, convertible securities, equity securities, or other instruments or rights in respect to the same issuer or a related entity.

Debt Securities—Bank Obligations. Time deposits are non-negotiable deposits maintained in a banking institution for a specified period of time at a stated interest rate. Certificates of deposit are negotiable short-term obligations of commercial banks. Variable rate certificates of deposit have an interest rate that is periodically adjusted prior to their stated maturity based upon a specified market rate. As a result of these adjustments, the interest rate on these obligations may be increased or decreased periodically. Frequently, dealers selling variable rate certificates of deposit to a fund will agree to repurchase such instruments, at the fund’s option, at par on or near the coupon dates. The dealers’ obligations to repurchase these instruments are subject to conditions imposed by various dealers; such conditions typically are the continued credit standing of the issuer and the existence of reasonably orderly market conditions. A fund is also able to sell variable rate certificates of deposit on the secondary market. Variable rate certificates of deposit normally carry a higher interest rate than comparable fixed-rate certificates of deposit. A banker’s acceptance is a time draft drawn on a commercial bank by a borrower usually in connection with an international commercial transaction (to finance the import, export, transfer, or storage of goods). The borrower is liable for payment, as is the bank, which unconditionally guarantees to pay the draft at its face amount on the maturity date. Most acceptances have maturities of 6 months or less and are traded in the secondary markets prior to maturity.

Debt Securities—Commercial Paper. Commercial paper refers to short-term, unsecured promissory notes issued by corporations to finance short-term credit needs. It is usually sold on a discount basis and has a maturity at the time of issuance not exceeding 9 months. High-quality commercial paper typically has the following characteristics: (1) liquidity ratios are adequate to meet cash requirements; (2) long-term senior debt is also high credit quality; (3) the issuer has access to at least two additional channels of borrowing; (4) basic earnings and cash flow have an upward trend with allowance made for unusual circumstances; (5) typically, the issuer’s industry is well established and the issuer has a strong position within the industry; and (6) the reliability and quality of management are unquestioned. In assessing the credit quality of commercial paper issuers, the following factors may be considered: (1) evaluation of the management of the issuer, (2) economic evaluation of the issuer’s industry or industries and the appraisal of speculative-type risks that may be inherent in certain areas, (3) evaluation of the issuer’s products in relation to competition and customer acceptance, (4) liquidity, (5) amount and quality of long-term debt, (6) trend of earnings over a period of ten years, (7) financial strength of a parent company and the relationships that exist with the issuer, and (8) recognition by the management of obligations that may be present or may arise as a result of public-interest questions and preparations to meet such obligations. The short-term nature of a commercial paper investment makes it less susceptible to interest rate risk than longer-term fixed income securities because interest rate risk typically increases as maturity lengths increase. Additionally, an issuer may expect to repay commercial paper obligations at maturity from the proceeds of the issuance of new commercial paper. As a result, investment in commercial paper is subject to the risk the issuer cannot issue enough new commercial paper to satisfy its outstanding commercial paper payment obligations, also known as rollover risk. Commercial paper may suffer from reduced liquidity due to certain circumstances, in particular, during stressed markets. In addition, as with all fixed income securities, an issuer may default on its commercial paper obligation.

Variable-amount master-demand notes are demand obligations that permit the investment of fluctuating amounts at varying market rates of interest pursuant to an arrangement between the issuer and a commercial bank acting as agent for the payees of such notes, whereby both parties have the right to vary the amount of the outstanding indebtedness on the notes. Because variable-amount master-demand notes are direct lending arrangements between a lender and a borrower, it is not generally contemplated that such instruments will be traded, and there is no secondary market for these notes, although they are redeemable (and thus immediately repayable by the borrower) at face value, plus accrued interest, at any time. In connection with a fund’s investment in variable-amount master-demand notes, Vanguard’s investment management staff will monitor, on an ongoing basis, the earning power, cash flow, and other liquidity ratios of the issuer, along with the borrower’s ability to pay principal and interest on demand.

Debt Securities —Emerging Market Risk. Investing in emerging market countries involves certain risks not typically associated with investing in the United States, and imposes risks greater than, or in addition to, risks of investing in more developed foreign countries. These risks include, but are not limited to, the following: nationalization or expropriation of assets or confiscatory taxation; greater social, economic, and political uncertainty and instability (including amplified risk of war and terrorism); more substantial government involvement in the economy; less government supervision and regulation of the securities markets and participants in those markets; controls on foreign investment and limitations on repatriation of invested capital; generally, smaller, less seasoned, and newly organized companies; the difference in, or lack of, auditing and financial reporting standards, which may result in unavailability of material information about issuers; difficulty in obtaining and/or enforcing a judgment in a court outside the United States; and greater price volatility, substantially less liquidity, and significantly smaller market capitalization of bond markets. Also, any change in the leadership or politics of emerging market countries, or the countries that exercise a significant influence over those countries, may halt the expansion of or reverse the liberalization of foreign investment policies now occurring and adversely affect existing investment opportunities. Furthermore, high rates of inflation and rapid fluctuations in inflation rates have had, and may continue to have, negative effects on the economies and bond markets of certain emerging market countries.

Debt Securities—Foreign Debt Securities. Foreign debt securities are debt securities issued by entities organized, domiciled, or with a principal executive office outside the United States, such as foreign governments and corporations. Foreign debt securities may trade in U.S. or foreign markets. Investing in foreign debt securities involves certain special risk considerations that are not typically associated with investing in debt securities of U.S. issuers.

Debt Securities—Inflation-Indexed Securities . Inflation-indexed securities are debt securities, the principal value of which is periodically adjusted to reflect the rate of inflation as indicated by the Consumer Price Index (CPI). Inflation-indexed securities may be issued by the U.S. government, by agencies and instrumentalities of the U.S. government, and by corporations. Two structures are common. The U.S. Treasury and some other issuers use a structure that accrues inflation into the principal value of the bond. Most other issuers pay out the CPI accruals as part of a semiannual coupon payment.

The periodic adjustment of U.S. inflation-indexed securities is tied to the CPI, which is calculated monthly by the U.S. Bureau of Labor Statistics. The CPI is a measurement of changes in the cost of living, made up of components such as housing, food, transportation, and energy. Inflation-indexed securities issued by a foreign government are generally adjusted to reflect a comparable inflation index, calculated by that government. There can be no assurance that the CPI or any foreign inflation index will accurately measure the real rate of inflation in the prices of goods and services. Moreover, there can be no assurance that the rate of inflation in a foreign country will correlate to the rate of inflation in the United States.

Inflation—a general rise in prices of goods and services—erodes the purchasing power of an investor’s portfolio. For example, if an investment provides a “nominal” total return of 5% in a given year and inflation is 2% during that period, the inflation-adjusted, or real, return is 3%. Inflation, as measured by the CPI, has generally occurred during the past 50 years, so investors should be conscious of both the nominal and real returns of their investments. Investors in inflation-indexed securities funds who do not reinvest the portion of the income distribution that is attributable to inflation adjustments will not maintain the purchasing power of the investment over the long term. This is because interest earned depends on the amount of principal invested, and that principal will not grow with inflation if the investor fails to reinvest the principal adjustment paid out as part of a fund’s income distributions. Although inflation-indexed securities are expected to be protected from long-term inflationary trends, short-term increases in inflation may lead to a decline in value. If interest rates rise because of reasons other than inflation (e.g., changes in currency exchange rates), investors in these securities may not be protected to the extent that the increase is not reflected in the bond’s inflation measure.

If the periodic adjustment rate measuring inflation (i.e., the CPI) falls, the principal value of inflation-indexed securities will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-indexed securities, even during a period of deflation. However, the current market value of the inflation-indexed securities is not guaranteed and will fluctuate. Other inflation-indexed securities include inflation-related bonds, which may or may not provide a similar guarantee. If a guarantee of principal is not provided, the adjusted principal value of the bond repaid at maturity may be less than the original principal.

B-9


 

The value of inflation-indexed securities should change in response to changes in real interest rates. Real interest rates, in turn, are tied to the relationship between nominal interest rates and the rate of inflation. Therefore, if inflation were to rise at a faster rate than nominal interest rates, real interest rates might decline, leading to an increase in value of inflation-indexed securities. In contrast, if nominal interest rates were to increase at a faster rate than inflation, real interest rates might rise, leading to a decrease in value of inflation-indexed securities.

Coupon payments that a fund receives from inflation-indexed securities are included in the fund’s gross income for the period during which they accrue. Any increase in principal for an inflation-indexed security resulting from inflation adjustments is considered by Internal Revenue Service (IRS) regulations to be taxable income in the year it occurs. For direct holders of an inflation-indexed security, this means that taxes must be paid on principal adjustments, even though these amounts are not received until the bond matures. By contrast, a fund holding these securities distributes both interest income and the income attributable to principal adjustments each quarter in the form of cash or reinvested shares (which, like principal adjustments, are taxable to shareholders). It may be necessary for the fund to liquidate portfolio positions, including when it is not advantageous to do so, in order to make required distributions.

Debt Securities—Non-Investment-Grade Securities . Non-investment-grade securities, also referred to as “high-yield securities” or “junk bonds,” are debt securities that are rated lower than the four highest rating categories by a nationally recognized statistical rating organization (e.g., lower than Baa3/P-2 by Moody’s Investors Service, Inc. (Moody’s) or below BBB–/A-2 by Standard & Poor’s Financial Services LLC (Standard & Poor’s)) or, if unrated, are determined to be of comparable quality by the fund’s advisor. These securities are generally considered to be, on balance, predominantly speculative with respect to capacity to pay interest and repay principal in accordance with the terms of the obligation, and they will generally involve more credit risk than securities in the investment-grade categories. Non-investment-grade securities generally provide greater income and opportunity for capital appreciation than higher quality securities, but they also typically entail greater price volatility and principal and income risk.

Analysis of the creditworthiness of issuers of high-yield securities may be more complex than for issuers of investment-grade securities. Thus, reliance on credit ratings in making investment decisions entails greater risks for high-yield securities than for investment-grade securities. The success of a fund’s advisor in managing high-yield securities is more dependent upon its own credit analysis than is the case with investment-grade securities.

Some high-yield securities are issued by smaller, less-seasoned companies, while others are issued as part of a corporate restructuring such as an acquisition, a merger, or a leveraged buyout. Companies that issue high-yield securities are often highly leveraged and may not have more traditional methods of financing available to them. Therefore, the risk associated with acquiring the securities of such issuers generally is greater than is the case with investment-grade securities. Some high-yield securities were once rated as investment-grade but have been downgraded to junk-bond status because of financial difficulties experienced by their issuers.

The market values of high-yield securities tend to reflect individual issuer developments to a greater extent than do investment-grade securities, which in general react to fluctuations in the general level of interest rates. High-yield securities also tend to be more sensitive to economic conditions than are investment-grade securities. An actual or anticipated economic downturn or sustained period of rising interest rates, for example, could cause a decline in junk bond prices because the advent of a recession could lessen the ability of a highly leveraged company to make principal and interest payments on its debt securities. If an issuer of high-yield securities defaults, in addition to risking payment of all or a portion of interest and principal, a fund investing in such securities may incur additional expenses to seek recovery.

The secondary market on which high-yield securities are traded may be less liquid than the market for investment-grade securities. Less liquidity in the secondary trading market could adversely affect the ability of a fund’s advisor to sell a high-yield security or the price at which a fund’s advisor could sell a high-yield security, and it could also adversely affect the daily net asset value of fund shares. When secondary markets for high-yield securities are less liquid than the market for investment-grade securities, it may be more difficult to value the securities because such valuation may require more research, and elements of judgment may play a greater role in the valuation of the securities.

Except as otherwise provided in a fund’s prospectus, if a credit-rating agency changes the rating of a portfolio security held by a fund, the fund may retain the portfolio security if the advisor deems it in the best interests of shareholders.

Debt Securities—Structured and Indexed Securities . Structured securities (also called “structured notes”) and indexed securities are derivative debt securities, the interest rate or principal of which is determined by an unrelated indicator. Indexed securities include structured notes as well as securities other than debt securities. The value of the

B-10


 

principal of and/or interest on structured and indexed securities is determined by reference to changes in the value of a specific asset, reference rate, or index (the reference) or the relative change in two or more references. The interest rate or the principal amount payable upon maturity or redemption may be increased or decreased, depending upon changes in the applicable reference. The terms of the structured and indexed securities may provide that, in certain circumstances, no principal is due at maturity and, therefore, may result in a loss of invested capital. Structured and indexed securities may be positively or negatively indexed, so that appreciation of the reference may produce an increase or a decrease in the interest rate or value of the security at maturity. In addition, changes in the interest rate or the value of the structured or indexed security at maturity may be calculated as a specified multiple of the change in the value of the reference; therefore, the value of such security may be very volatile. Structured and indexed securities may entail a greater degree of market risk than other types of debt securities because the investor bears the risk of the reference. Structured or indexed securities may also be more volatile, less liquid, and more difficult to accurately price than less complex securities or more traditional debt securities, which could lead to an overvaluation or an undervaluation of the securities.

Debt Securities—U.S. Government Securities . The term “U.S. government securities” refers to a variety of debt securities that are issued or guaranteed by the U.S. Treasury, by various agencies of the U.S. government, or by various instrumentalities that have been established or sponsored by the U.S. government. The term also refers to repurchase agreements collateralized by such securities.

U.S. Treasury securities are backed by the full faith and credit of the U.S. government, meaning that the U.S. government is required to repay the principal in the event of default. Other types of securities issued or guaranteed by federal agencies and U.S. government-sponsored instrumentalities may or may not be backed by the full faith and credit of the U.S. government. The U.S. government, however, does not guarantee the market price of any U.S. government securities. In the case of securities not backed by the full faith and credit of the U.S. government, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment and may not be able to assert a claim against the United States itself in the event the agency or instrumentality does not meet its commitment.

Some of the U.S. government agencies that issue or guarantee securities include the Government National Mortgage Association, the Export-Import Bank of the United States, the Federal Housing Administration, the Maritime Administration, the Small Business Administration, and the Tennessee Valley Authority. An instrumentality of the U.S. government is a government agency organized under federal charter with government supervision. Instrumentalities issuing or guaranteeing securities include, among others, the Federal Deposit Insurance Corporation, the Federal Home Loan Banks, and the Federal National Mortgage Association.

Debt Securities—Variable and Floating Rate Securities . Variable and floating rate securities are debt securities that provide for periodic adjustments in the interest rate paid on the security. Variable rate securities provide for a specified periodic adjustment in the interest rate, while floating rate securities have interest rates that change whenever there is a change in a designated benchmark rate or the issuer’s credit quality. There is a risk that the current interest rate on variable and floating rate securities may not accurately reflect current market interest rates or adequately compensate the holder for the current creditworthiness of the issuer. Some variable or floating rate securities are structured with liquidity features such as (1) put options or tender options that permit holders (sometimes subject to conditions) to demand payment of the unpaid principal balance plus accrued interest from the issuers or certain financial intermediaries or (2) auction-rate features, remarketing provisions, or other maturity-shortening devices designed to enable the issuer to refinance or redeem outstanding debt securities (market-dependent liquidity features). Variable or floating rate securities that include market-dependent liquidity features may have greater liquidity risk than other securities. The greater liquidity risk may exist, for example, because of the failure of a market-dependent liquidity feature to operate as intended (as a result of the issuer’s declining creditworthiness, adverse market conditions, or other factors) or the inability or unwillingness of a participating broker-dealer to make a secondary market for such securities. As a result, variable or floating rate securities that include market-dependent liquidity features may lose value, and the holders of such securities may be required to retain them until the later of the repurchase date, the resale date, or the date of maturity. A demand instrument with a demand notice exceeding seven days may be considered illiquid if there is no secondary market for such security.

Debt Securities—Zero-Coupon and Pay-in-Kind Securities . Zero-coupon and pay-in-kind securities are debt securities that do not make regular cash interest payments. Zero-coupon securities generally do not pay interest. Zero-coupon Treasury bonds are U.S. Treasury notes and bonds that have been stripped of their unmatured interest coupons, or the

B-11


 

coupons themselves, and also receipts or certificates representing an interest in such stripped debt obligations and coupons. The timely payment of coupon interest and principal on these instruments remains guaranteed by the full faith and credit of the U.S. government. Pay-in-kind securities pay interest through the issuance of additional securities. These securities are generally issued at a discount to their principal or maturity value. Because such securities do not pay current cash income, the price of these securities can be volatile when interest rates fluctuate. Although these securities do not pay current cash income, federal income tax law requires the holders of zero-coupon and pay-in-kind securities to include in income each year the portion of the original issue discount and other noncash income on such securities accrued during that year. Each fund that holds such securities intends to pass along such interest as a component of the fund’s distributions of net investment income. It may be necessary for the fund to liquidate portfolio positions, including when it is not advantageous to do so, in order to make required distributions.

Depositary Receipts . Depositary receipts (also sold as participatory notes) are securities that evidence ownership interests in a security or a pool of securities that have been deposited with a “depository.” Depositary receipts may be sponsored or unsponsored and include American Depositary Receipts (ADRs), European Depositary Receipts (EDRs), and Global Depositary Receipts (GDRs). For ADRs, the depository is typically a U.S. financial institution, and the underlying securities are issued by a foreign issuer. For other depositary receipts, the depository may be a foreign or a U.S. entity, and the underlying securities may have a foreign or a U.S. issuer. Depositary receipts will not necessarily be denominated in the same currency as their underlying securities. Generally, ADRs are issued in registered form, denominated in U.S. dollars, and designed for use in the U.S. securities markets. Other depositary receipts, such as GDRs and EDRs, may be issued in bearer form and denominated in other currencies, and they are generally designed for use in securities markets outside the United States. Although the two types of depositary receipt facilities (sponsored and unsponsored) are similar, there are differences regarding a holder’s rights and obligations and the practices of market participants.

A depository may establish an unsponsored facility without participation by (or acquiescence of) the underlying issuer; typically, however, the depository requests a letter of nonobjection from the underlying issuer prior to establishing the facility. Holders of unsponsored depositary receipts generally bear all the costs of the facility. The depository usually charges fees upon the deposit and withdrawal of the underlying securities, the conversion of dividends into U.S. dollars or other currency, the disposition of noncash distributions, and the performance of other services. The depository of an unsponsored facility frequently is under no obligation to distribute shareholder communications received from the underlying issuer or to pass through voting rights to depositary receipt holders with respect to the underlying securities.

Sponsored depositary receipt facilities are created in generally the same manner as unsponsored facilities, except that sponsored depositary receipts are established jointly by a depository and the underlying issuer through a deposit agreement. The deposit agreement sets out the rights and responsibilities of the underlying issuer, the depository, and the depositary receipt holders. With sponsored facilities, the underlying issuer typically bears some of the costs of the depositary receipts (such as dividend payment fees of the depository), although most sponsored depositary receipt holders may bear costs such as deposit and withdrawal fees. Depositories of most sponsored depositary receipts agree to distribute notices of shareholder meetings, voting instructions, and other shareholder communications and information to the depositary receipt holders at the underlying issuer’s request.

For purposes of a fund’s investment policies, investments in depositary receipts will be deemed to be investments in the underlying securities. Thus, a depositary receipt representing ownership of common stock will be treated as common stock. Depositary receipts do not eliminate all of the risks associated with directly investing in the securities of foreign issuers.

Derivatives . A derivative is a financial instrument that has a value based on—or “derived from”—the values of other assets, reference rates, or indexes. Derivatives may relate to a wide variety of underlying references, such as commodities, stocks, bonds, interest rates, currency exchange rates, and related indexes. Derivatives include futures contracts and options on futures contracts, certain forward-commitment transactions, options on securities, caps, floors, collars, swap agreements, and certain other financial instruments. Some derivatives, such as futures contracts and certain options, are traded on U.S. commodity and securities exchanges, while other derivatives, such as swap agreements, may be privately negotiated and entered into in the over-the-counter market (OTC Derivatives) or may be cleared through a clearinghouse (Cleared Derivatives) and traded on an exchange or swap execution facility. As a result of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the Dodd-Frank Act), certain swap agreements, such as certain standardized credit default and interest rate swap agreements, must be cleared through a clearinghouse and traded on an exchange or swap execution facility. This could result in an increase in the overall costs of such transactions.

B-12


 

While the intent of derivatives regulatory reform is to mitigate risks associated with derivatives markets, the new regulations could, among other things, increase liquidity and decrease pricing for more standardized products while decreasing liquidity and increasing pricing for less standardized products. The risks associated with the use of derivatives are different from, and possibly greater than, the risks associated with investing directly in the securities or assets on which the derivatives are based.

Derivatives may be used for a variety of purposes including—but not limited to—hedging, managing risk, seeking to stay fully invested, seeking to reduce transaction costs, seeking to simulate an investment in equity or debt securities or other investments, and seeking to add value by using derivatives to more efficiently implement portfolio positions when derivatives are favorably priced relative to equity or debt securities or other investments. Some investors may use derivatives primarily for speculative purposes while other uses of derivatives may not constitute speculation. There is no assurance that any derivatives strategy used by a fund’s advisor will succeed. The other parties to the funds’ OTC Derivatives contracts (usually referred to as “counterparties”) will not be considered the issuers thereof for purposes of certain provisions of the 1940 Act and the IRC, although such OTC Derivatives may qualify as securities or investments under such laws. The funds’ advisors, however, will monitor and adjust, as appropriate, the funds’ credit risk exposure to OTC Derivative counterparties.

Derivative products are highly specialized instruments that require investment techniques and risk analyses different from those associated with stocks, bonds, and other traditional investments. The use of a derivative requires an understanding not only of the underlying instrument but also of the derivative itself, without the benefit of observing the performance of the derivative under all possible market conditions.

When the fund enters into a Cleared Derivative, an initial margin deposit with a Futures Commission Merchant (FCM) is required. Initial margin deposits are typically calculated as an amount equal to the volatility in market value of a Cleared Derivative over a fixed period. If the value of the fund’s Cleared Derivatives declines, the fund will be required to make additional “variation margin” payments to the FCM to settle the change in value. If the value of the fund’s Cleared Derivatives increases, the FCM will be required to make additional “variation margin” payments to the fund to settle the change in value. This process is known as “marking-to-market” and is calculated on a daily basis.

For OTC Derivatives, the fund is subject to the risk that a loss may be sustained as a result of the insolvency or bankruptcy of the counterparty or the failure of the counterparty to make required payments or otherwise comply with the terms of the contract. Additionally, the use of credit derivatives can result in losses if a fund’s advisor does not correctly evaluate the creditworthiness of the issuer on which the credit derivative is based.

Derivatives may be subject to liquidity risk, which exists when a particular derivative is difficult to purchase or sell. If a derivative transaction is particularly large or if the relevant market is illiquid (as is the case with certain OTC Derivatives), it may not be possible to initiate a transaction or liquidate a position at an advantageous time or price.

Derivatives may be subject to pricing or “basis” risk, which exists when a particular derivative becomes extraordinarily expensive relative to historical prices or the prices of corresponding cash market instruments. Under certain market conditions, it may not be economically feasible to initiate a transaction or liquidate a position in time to avoid a loss or take advantage of an opportunity.

Because certain derivatives have a leverage component, adverse changes in the value or level of the underlying asset, reference rate, or index can result in a loss substantially greater than the amount invested in the derivative itself. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment. A derivative transaction will not be considered to constitute the issuance, by a fund, of a “senior security,” as that term is defined in Section 18(g) of the 1940 Act, and therefore such transaction will not be subject to the 300% asset coverage requirement otherwise applicable to borrowings by a fund, if the fund covers the transaction in accordance with the requirements described under the heading “ Borrowing .”

Like most other investments, derivative instruments are subject to the risk that the market value of the instrument will change in a way detrimental to a fund’s interest. A fund bears the risk that its advisor will incorrectly forecast future market trends or the values of assets, reference rates, indexes, or other financial or economic factors in establishing derivative positions for the fund. If the advisor attempts to use a derivative as a hedge against, or as a substitute for, a portfolio investment, the fund will be exposed to the risk that the derivative will have or will develop imperfect or no correlation with the portfolio investment. This could cause substantial losses for the fund. Although hedging strategies involving derivative instruments can reduce the risk of loss, they can also reduce the opportunity for gain or even result in losses by offsetting favorable price movements in other fund investments. Many derivatives (in particular, OTC

B-13


 

Derivatives) are complex and often valued subjectively. Improper valuations can result in increased cash payment requirements to counterparties or a loss of value to a fund.

Eurodollar and Yankee Obligations. Eurodollar bank obligations are dollar-denominated certificates of deposit and time deposits issued outside the U.S. capital markets by foreign branches of U.S. banks and by foreign banks. Yankee bank obligations are dollar-denominated obligations issued in the U.S. capital markets by foreign banks.

Eurodollar and Yankee obligations are subject to the same risks that pertain to domestic issuers, most notably income risk (and, to a lesser extent, credit risk, market risk, and liquidity risk). Additionally, Eurodollar (and, to a limited extent, Yankee) obligations are subject to certain sovereign risks. One such risk is the possibility that a sovereign country might prevent capital, in the form of dollars, from flowing across its borders. Other risks include adverse political and economic developments, the extent and quality of government regulation of financial markets and institutions, the imposition of foreign withholding taxes, and expropriation or nationalization of foreign issuers. However, Eurodollar and Yankee obligations will undergo the same type of credit analysis as domestic issuers in which a Vanguard fund invests, and they will have at least the same financial strength as the domestic issuers approved for the fund.

Exchange-Traded Funds . A fund may purchase shares of exchange-traded funds (ETFs). Typically, a fund would purchase ETF shares for the same reason it would purchase (and as an alternative to purchasing) futures contracts: to obtain exposure to all or a portion of the stock or bond market. ETF shares enjoy several advantages over futures. Depending on the market, the holding period, and other factors, ETF shares can be less costly and more tax-efficient than futures. In addition, ETF shares can be purchased for smaller sums, offer exposure to market sectors and styles for which there is no suitable or liquid futures contract, and do not involve leverage.

An investment in an ETF generally presents the same principal risks as an investment in a conventional fund (i.e., one that is not exchange-traded) that has the same investment objective, strategies, and policies. The price of an ETF can fluctuate within a wide range, and a fund could lose money investing in an ETF if the prices of the securities owned by the ETF go down. In addition, ETFs are subject to the following risks that do not apply to conventional funds: (1) the market price of an ETF’s shares may trade at a discount or a premium to their net asset value; (2) an active trading market for an ETF’s shares may not develop or be maintained; and (3) trading of an ETF’s shares may be halted by the activation of individual or marketwide trading halts (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). Trading of an ETF’s shares may also be halted if the shares are delisted from the exchange without first being listed on another exchange or if the listing exchange’s officials determine that such action is appropriate in the interest of a fair and orderly market or for the protection of investors.

Most ETFs are investment companies. Therefore, a fund’s purchases of ETF shares generally are subject to the limitations on, and the risks of, a fund’s investments in other investment companies, which are described under the heading “ Other Investment Companies .”

Foreign Securities. Typically, foreign securities are considered to be equity or debt securities issued by entities organized, domiciled, or with a principal executive office outside the United States, such as foreign corporations and governments. Securities issued by certain companies organized outside the United States may not be deemed to be foreign securities if the company’s principal operations are conducted from the United States or when the company’s equity securities trade principally on a U.S. stock exchange. Foreign securities may trade in U.S. or foreign securities markets. A fund may make foreign investments either directly by purchasing foreign securities or indirectly by purchasing depositary receipts or depositary shares of similar instruments (depositary receipts) for foreign securities. Direct investments in foreign securities may be made either on foreign securities exchanges or in the over-the-counter (OTC) markets. Investing in foreign securities involves certain special risk considerations that are not typically associated with investing in securities of U.S. companies or governments.

Because foreign issuers are not generally subject to uniform accounting, auditing, and financial reporting standards and practices comparable to those applicable to U.S. issuers, there may be less publicly available information about certain foreign issuers than about U.S. issuers. Evidence of securities ownership may be uncertain in many foreign countries. As a result, there are multiple risks that could result in a loss to the fund, including, but not limited to, the risk that a fund’s trade details could be incorrectly or fraudulently entered at the time of a transaction. Securities of foreign issuers are generally more volatile and less liquid than securities of comparable U.S. issuers, and foreign investments may be effected through structures that may be complex or confusing. In certain countries, there is less government supervision and regulation of stock exchanges, brokers, and listed companies than in the United States. The risk that securities traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by government

B-14


 

authorities, is also heightened. In addition, with respect to certain foreign countries, there is the possibility of expropriation or confiscatory taxation, political or social instability, war, terrorism, nationalization, limitations on the removal of funds or other assets, or diplomatic developments that could affect U.S. investments in those countries. Additionally, economic or other sanctions imposed on the United States by a foreign country, or imposed on a foreign country or issuer by the United States, could impair a fund’s ability to buy, sell, hold, receive, deliver, or otherwise transact in certain investment securities. Sanctions could also affect the value and/or liquidity of a foreign security.

Although an advisor will endeavor to achieve the most favorable execution costs for a fund’s portfolio transactions in foreign securities under the circumstances, commissions and other transaction costs are generally higher than those on U.S. securities. In addition, it is expected that the custodian arrangement expenses for a fund that invests primarily in foreign securities will be somewhat greater than the expenses for a fund that invests primarily in domestic securities. Additionally, bankruptcy laws vary by jurisdiction and cash deposits may be subject to a custodian’s creditors. Certain foreign governments levy withholding or other taxes against dividend and interest income from, capital gains on the sale of, or transactions in foreign securities. Although in some countries a portion of these taxes is recoverable by the fund, the nonrecovered portion of foreign withholding taxes will reduce the income received from such securities.

The value of the foreign securities held by a fund that are not U.S. dollar-denominated may be significantly affected by changes in currency exchange rates. The U.S. dollar value of a foreign security generally decreases when the value of the U.S. dollar rises against the foreign currency in which the security is denominated, and it tends to increase when the value of the U.S. dollar falls against such currency (as discussed under the heading “ Foreign Securities—Foreign Currency Transactions ,” a fund may attempt to hedge its currency risks). In addition, the value of fund assets may be affected by losses and other expenses incurred from converting between various currencies in order to purchase and sell foreign securities, as well as by currency restrictions, exchange control regulations, currency devaluations, and political and economic developments.

Foreign Securities—China A-shares Risk. China A-shares (A-shares) are shares of mainland Chinese companies that are traded locally on the Shanghai and Shenzhen stock exchanges. In order to invest in A-shares, a foreign investor must have access to an investment quota through a Qualified Foreign Institutional Investor (QFII) or a Renminbi QFII (RQFII) license holder. A-shares are also available through the China Stock Connect program, subject to separate quota limitations. The developing state of the investment and banking systems of the People’s Republic of China (China, or the PRC) subjects the settlement, clearing, and registration of securities transactions to heightened risks. Additionally, there are foreign ownership limitations that may result in limitations on investment or the return of profits if a fund purchases and sells shares of an issuer in which it owns 5% or more of the shares issued within a six-month period. It is unclear if the 5% ownership will be determined by aggregating the holdings of a fund with affiliated funds.

Due to these restrictions, it is possible that the A-shares quota available to a fund as a foreign investor may not be sufficient to meet the fund’s investment needs. In this situation, a fund may seek an alternative method of economic exposure, such as by purchasing other classes of securities or depositary receipts or by utilizing derivatives. Any of these options could increase a fund’s index sampling risk (for index funds) or investment cost. Additionally, investing in A-shares generally increases emerging markets risk due in part to government and issuer market controls and the developing settlement and legal systems.

Investing in China A-shares through Stock Connect . The China Stock Connect program (Stock Connect) is a mutual market access program designed to, among other things, enable foreign investment in the PRC via brokers in Hong Kong. A QFII/RQFII license is not required to trade via Stock Connect. There are significant risks inherent in investing in A-shares through Stock Connect. Specifically, trading can be affected by a number of issues. Stock Connect can only operate when both PRC and Hong Kong markets are open for trading and when banking services are available in both markets on the corresponding settlement days. As such, if one or both markets are closed on a U.S. trading day, a fund may not be able to dispose of its shares in a timely manner, which could adversely affect the fund’s performance. Trading through Stock Connect generally requires pre-delivery of cash or securities to a broker. If the cash or securities are not in the broker’s possession before the market opens on the day of selling, the sell order will be rejected. This requirement may limit a fund’s ability to dispose of its A-shares purchased through Stock Connect in a timely manner.

Additionally, Stock Connect is subject to daily quota limitations on purchases into the PRC. Once the daily quota is reached, orders to purchase additional A-shares through Stock Connect will be rejected. In addition, a fund’s purchase of A-shares through Stock Connect may only be subsequently sold through Stock Connect and is not otherwise transferable. Stock Connect utilizes an omnibus clearing structure, and the fund’s shares will be registered in its

B-15


 

custodian’s name on the Hong Kong Central Clearing and Settlement System. This may limit an advisor’s ability to effectively manage a fund’s holdings, including the potential enforcement of equity owner rights.

Foreign Securities—Emerging Market Risk. Investing in emerging market countries involves certain risks not typically associated with investing in the United States, and it imposes risks greater than, or in addition to, risks of investing in more developed foreign countries. These risks include, but are not limited to, the following: nationalization or expropriation of assets or confiscatory taxation; currency devaluations and other currency exchange rate fluctuations; greater social, economic, and political uncertainty and instability (including amplified risk of war and terrorism); more substantial government involvement in the economy; less government supervision and regulation of the securities markets and participants in those markets and possible arbitrary and unpredictable enforcement of securities regulations and other laws; controls on foreign investment and limitations on repatriation of invested capital and on the fund’s ability to exchange local currencies for U.S. dollars; unavailability of currency-hedging techniques in certain emerging market countries; generally smaller, less seasoned, or newly organized companies; differences in, or lack of, auditing and financial reporting standards, which may result in unavailability of material information about issuers; difficulty in obtaining and/or enforcing a judgment in a court outside the United States; and greater price volatility, substantially less liquidity, and significantly smaller market capitalization of securities markets. Also, any change in the leadership or politics of emerging market countries, or the countries that exercise a significant influence over those countries, may halt the expansion of or reverse the liberalization of foreign investment policies now occurring and adversely affect existing investment opportunities. Furthermore, high rates of inflation and rapid fluctuations in inflation rates have had, and may continue to have, negative effects on the economies and securities markets of certain emerging market countries. Custodial services and other investment-related costs are often more expensive in emerging market countries, which can reduce a fund’s income from investments in securities or debt instruments of emerging market country issuers.

Foreign Securities—Foreign Currency Transactions. The value in U.S. dollars of a fund’s non-dollar-denominated foreign securities may be affected favorably or unfavorably by changes in foreign currency exchange rates and exchange control regulations, and the fund may incur costs in connection with conversions between various currencies. To seek to minimize the impact of such factors on net asset values, a fund may engage in foreign currency transactions in connection with its investments in foreign securities. A fund will enter into foreign currency transactions only to attempt to “hedge” the currency risk associated with investing in foreign securities. Although such transactions tend to minimize the risk of loss that would result from a decline in the value of the hedged currency, they also may limit any potential gain that might result should the value of such currency increase.

Currency exchange transactions may be conducted either on a spot (i.e., cash) basis at the rate prevailing in the currency exchange market or through forward contracts to purchase or sell foreign currencies. A forward currency contract involves an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties, at a price set at the time of the contract. These contracts are entered into with large commercial banks or other currency traders who are participants in the interbank market. Currency exchange transactions also may be effected through the use of swap agreements or other derivatives.

Currency exchange transactions may be considered borrowings. A currency exchange transaction will not be considered to constitute the issuance, by a fund, of a “senior security,” as that term is defined in Section 18(g) of the 1940 Act, and therefore such transaction will not be subject to the 300% asset coverage requirement otherwise applicable to borrowings by a fund, if the fund covers the transaction in accordance with the requirements described under the heading “ Borrowing .”

By entering into a forward contract for the purchase or sale of foreign currency involved in underlying security transactions, a fund may be able to protect itself against part or all of the possible loss between trade and settlement dates for that purchase or sale resulting from an adverse change in the relationship between the U.S. dollar and such foreign currency. This practice is sometimes referred to as “transaction hedging.” In addition, when the advisor reasonably believes that a particular foreign currency may suffer a substantial decline against the U.S. dollar, a fund may enter into a forward contract to sell an amount of foreign currency approximating the value of some or all of its portfolio securities denominated in such foreign currency. This practice is sometimes referred to as “portfolio hedging.” Similarly, when the advisor reasonably believes that the U.S. dollar may suffer a substantial decline against a foreign currency, a fund may enter into a forward contract to buy that foreign currency for a fixed dollar amount.

B-16


 

A fund may also attempt to hedge its foreign currency exchange rate risk by engaging in currency futures, options, and “cross-hedge” transactions. In cross-hedge transactions, a fund holding securities denominated in one foreign currency will enter into a forward currency contract to buy or sell a different foreign currency (one that the advisor reasonably believes generally tracks the currency being hedged with regard to price movements). The advisor may select the tracking (or substitute) currency rather than the currency in which the security is denominated for various reasons, including in order to take advantage of pricing or other opportunities presented by the tracking currency or to take advantage of a more liquid or more efficient market for the tracking currency. Such cross-hedges are expected to help protect a fund against an increase or decrease in the value of the U.S. dollar against certain foreign currencies.

A fund may hold a portion of its assets in bank deposits denominated in foreign currencies so as to facilitate investment in foreign securities as well as protect against currency fluctuations and the need to convert such assets into U.S. dollars (thereby also reducing transaction costs). To the extent these assets are converted back into U.S. dollars, the value of the assets so maintained will be affected favorably or unfavorably by changes in foreign currency exchange rates and exchange control regulations.

The forecasting of currency market movement is extremely difficult, and whether any hedging strategy will be successful is highly uncertain. Moreover, it is impossible to forecast with precision the market value of portfolio securities at the expiration of a forward currency contract. Accordingly, a fund may be required to buy or sell additional currency on the spot market (and bear the expense of such transaction) if its advisor’s predictions regarding the movement of foreign currency or securities markets prove inaccurate. In addition, the use of cross-hedging transactions may involve special risks and may leave a fund in a less advantageous position than if such a hedge had not been established. Because forward currency contracts are privately negotiated transactions, there can be no assurance that a fund will have flexibility to roll over a forward currency contract upon its expiration if it desires to do so. Additionally, there can be no assurance that the other party to the contract will perform its services thereunder.

Foreign Securities—Foreign Investment Companies. Some of the countries in which a fund may invest may not permit, or may place economic restrictions on, direct investment by outside investors. Fund investments in such countries may be permitted only through foreign government-approved or authorized investment vehicles, which may include other investment companies. Such investments may be made through registered or unregistered closed-end investment companies that invest in foreign securities. Investing through such vehicles may involve layered fees or expenses and may also be subject to the limitations on, and the risks of, a fund’s investments in other investment companies, which are described under the heading “ Other Investment Companies.

Foreign Securities—Russian Market Risk. There are significant risks inherent in investing in Russian securities. The underdeveloped state of Russia’s banking system subjects the settlement, clearing, and registration of securities transactions to significant risks. In March of 2013, the National Settlement Depository (NSD) began acting as a central depository for the majority of Russian equity securities; the NSD is now recognized as the Central Securities Depository in Russia.

For Russian issuers with fewer than 50 shareholders, ownership records are maintained only by registrars who are under contract with the issuers and are currently not settled with the NSD. Although a Russian subcustodian will maintain copies of the registrar’s records (Share Extracts) on its premises, such Share Extracts are not recorded with the NSD and may not be legally sufficient to establish ownership of securities. The registrars may not be independent from the issuer, are not necessarily subject to effective state supervision, and may not be licensed with any governmental entity. A fund will endeavor to ensure by itself or through a custodian or other agent that the fund’s interest continues to be appropriately recorded for Russian issuers with fewer than 50 shareholders by inspecting the share register and by obtaining extracts of share registers through regular confirmations. However, these extracts have no legal enforceability, and the possibility exists that a subsequent illegal amendment or other fraudulent act may deprive the fund of its ownership rights or may improperly dilute its interest. In addition, although applicable Russian regulations impose liability on registrars for losses resulting from their errors, a fund may find it difficult to enforce any rights it may have against the registrar or issuer of the securities in the event of loss of share registration.

Futures Contracts and Options on Futures Contracts. Futures contracts and options on futures contracts are derivatives. A futures contract is a standardized agreement between two parties to buy or sell at a specific time in the future a specific quantity of a commodity at a specific price. The commodity may consist of an asset, a reference rate, or an index. A security futures contract relates to the sale of a specific quantity of shares of a single equity security or a narrow-based securities index. The value of a futures contract tends to increase and decrease in tandem with the value of the underlying

B-17


 

commodity. The buyer of a futures contract enters into an agreement to purchase the underlying commodity on the settlement date and is said to be “long” the contract. The seller of a futures contract enters into an agreement to sell the underlying commodity on the settlement date and is said to be “short” the contract. The price at which a futures contract is entered into is established either in the electronic marketplace or by open outcry on the floor of an exchange between exchange members acting as traders or brokers. Open futures contracts can be liquidated or closed out by physical delivery of the underlying commodity or payment of the cash settlement amount on the settlement date, depending on the terms of the particular contract. Some financial futures contracts (such as security futures) provide for physical settlement at maturity. Other financial futures contracts (such as those relating to interest rates, foreign currencies, and broad-based securities indexes) generally provide for cash settlement at maturity. In the case of cash-settled futures contracts, the cash settlement amount is equal to the difference between the final settlement or market price for the relevant commodity on the last trading day of the contract and the price for the relevant commodity agreed upon at the outset of the contract. Most futures contracts, however, are not held until maturity but instead are “offset” before the settlement date through the establishment of an opposite and equal futures position.

The purchaser or seller of a futures contract is not required to deliver or pay for the underlying commodity unless the contract is held until the settlement date. However, both the purchaser and seller are required to deposit “initial margin” with a futures commission merchant (FCM) when the futures contract is entered into. Initial margin deposits are typically calculated as an amount equal to the volatility in market value of a contract over a fixed period. If the value of the fund’s position declines, the fund will be required to make additional “variation margin” payments to the FCM to settle the change in value. If the value of the fund’s position increases, the FCM will be required to make additional “variation margin” payments to the fund to settle the change in value. This process is known as “marking-to-market” and is calculated on a daily basis. A futures transaction will not be considered to constitute the issuance, by a fund, of a “senior security,” as that term is defined in Section 18(g) of the 1940 Act, and therefore such transaction will not be subject to the 300% asset coverage requirement otherwise applicable to borrowings by a fund, if the fund covers the transaction in accordance with the requirements described under the heading “ Borrowing .”

An option on a futures contract (or futures option) conveys the right, but not the obligation, to purchase (in the case of a call option) or sell (in the case of a put option) a specific futures contract at a specific price (called the “exercise” or “strike” price) any time before the option expires. The seller of an option is called an option writer. The purchase price of an option is called the premium. The potential loss to an option buyer is limited to the amount of the premium plus transaction costs. This will be the case, for example, if the option is held and not exercised prior to its expiration date. Generally, an option writer sells options with the goal of obtaining the premium paid by the option buyer. If an option sold by an option writer expires without being exercised, the writer retains the full amount of the premium. The option writer, however, has unlimited economic risk because its potential loss, except to the extent offset by the premium received when the option was written, is equal to the amount the option is “in-the-money” at the expiration date. A call option is in-the-money if the value of the underlying futures contract exceeds the exercise price of the option. A put option is in-the-money if the exercise price of the option exceeds the value of the underlying futures contract. Generally, any profit realized by an option buyer represents a loss for the option writer.

A fund that takes the position of a writer of a futures option is required to deposit and maintain initial and variation margin with respect to the option, as previously described in the case of futures contracts. A futures option transaction will not be considered to constitute the issuance, by a fund, of a “senior security,” as that term is defined in Section 18(g) of the 1940 Act, and therefore such transaction will not be subject to the 300% asset coverage requirement otherwise applicable to borrowings by a fund, if the fund covers the transaction in accordance with the requirements described under the heading “ Borrowing .”

The Fund intends to comply with Rule 4.5 under the Commodity Exchange Act (CEA), under which a mutual fund may be excluded from the definition of the term Commodity Pool Operator (CPO) if the fund meets certain conditions such as limiting its investments in certain CEA-regulated instruments (e.g., futures, options, or swaps) and complying with certain marketing restrictions. Accordingly, Vanguard is not subject to registration or regulation as a CPO with respect to the Fund under the CEA. The Fund will only enter into futures contracts and futures options that are traded on a U.S. or foreign exchange, board of trade, or similar entity or that are quoted on an automated quotation system.

Futures Contracts and Options on Futures Contracts—Risks. The risk of loss in trading futures contracts and in writing futures options can be substantial because of the low margin deposits required, the extremely high degree of leverage involved in futures and options pricing, and the potential high volatility of the futures markets. As a result, a relatively small price movement in a futures position may result in immediate and substantial loss (or gain) for the

B-18


 

investor. For example, if at the time of purchase, 10% of the value of the futures contract is deposited as margin, a subsequent 10% decrease in the value of the futures contract would result in a total loss of the margin deposit, before any deduction for the transaction costs, if the account were then closed out. A 15% decrease would result in a loss equal to 150% of the original margin deposit if the contract were closed out. Thus, a purchase or sale of a futures contract, and the writing of a futures option, may result in losses in excess of the amount invested in the position. In the event of adverse price movements, a fund would continue to be required to make daily cash payments to maintain its required margin. In such situations, if the fund has insufficient cash, it may have to sell portfolio securities to meet daily margin requirements (and segregation requirements, if applicable) at a time when it may be disadvantageous to do so. In addition, on the settlement date, a fund may be required to make delivery of the instruments underlying the futures positions it holds.

A fund could suffer losses if it is unable to close out a futures contract or a futures option because of an illiquid secondary market. Futures contracts and futures options may be closed out only on an exchange that provides a secondary market for such products. However, there can be no assurance that a liquid secondary market will exist for any particular futures product at any specific time. Thus, it may not be possible to close a futures or option position. Moreover, most futures exchanges limit the amount of fluctuation permitted in futures contract prices during a single trading day. The daily limit establishes the maximum amount that the price of a futures contract may vary either up or down from the previous day’s settlement price at the end of a trading session. Once the daily limit has been reached in a particular type of contract, no trades may be made on that day at a price beyond that limit. The daily limit governs only price movement during a particular trading day, and therefore does not limit potential losses because the limit may prevent the liquidation of unfavorable positions. Futures contract prices have occasionally moved to the daily limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of future positions and subjecting some futures traders to substantial losses. The inability to close futures and options positions also could have an adverse impact on the ability to hedge a portfolio investment or to establish a substitute for a portfolio investment.

U.S.       Treasury futures are generally not subject to such daily limits.
A       fund bears the risk that its advisor will incorrectly predict future market trends. If the advisor attempts to use a futures

contract or a futures option as a hedge against, or as a substitute for, a portfolio investment, the fund will be exposed to the risk that the futures position will have or will develop imperfect or no correlation with the portfolio investment. This could cause substantial losses for the fund. Although hedging strategies involving futures products can reduce the risk of loss, they can also reduce the opportunity for gain or even result in losses by offsetting favorable price movements in other fund investments.

A fund could lose margin payments it has deposited with its FCM if, for example, the FCM breaches its agreement with the fund or becomes insolvent or goes into bankruptcy. In that event, the fund may be entitled to return of margin owed to it only in proportion to the amount received by the FCM’s other customers, potentially resulting in losses to the fund.

Hybrid Instruments . A hybrid instrument, or hybrid, is an interest in an issuer that combines the characteristics of an equity security, a debt security, a commodity, and/or a derivative. A hybrid may have characteristics that, on the whole, more strongly suggest the existence of a bond, stock, or other traditional investment, but a hybrid may also have prominent features that are normally associated with a different type of investment. Moreover, hybrid instruments may be treated as a particular type of investment for one regulatory purpose (such as taxation) and may be simultaneously treated as a different type of investment for a different regulatory purpose (such as securities or commodity regulation). Hybrids can be used as an efficient means of pursuing a variety of investment goals, including increased total return, duration management, and currency hedging. Because hybrids combine features of two or more traditional investments and may involve the use of innovative structures, hybrids present risks that may be similar to, different from, or greater than those associated with traditional investments with similar characteristics.

Examples of hybrid instruments include convertible securities, which combine the investment characteristics of bonds and common stocks; perpetual bonds, which are structured like fixed income securities, have no maturity date, and may be characterized as debt or equity for certain regulatory purposes; contingent convertible securities, which are fixed income securities that, under certain circumstances, either convert into common stock of the issuer or undergo a principal write-down by a predetermined percentage if the issuer’s capital ratio falls below a predetermined trigger level; and trust-preferred securities, which are preferred stocks of a special-purpose trust that holds subordinated debt of the corporate parent. Another example of a hybrid is a commodity-linked bond, such as a bond issued by an oil company that

B-19


 

pays a small base level of interest with additional interest that accrues in correlation to the extent to which oil prices exceed a certain predetermined level. Such a hybrid would be a combination of a bond and a call option on oil.

In the case of hybrids that are structured like fixed income securities (such as structured notes), the principal amount or the interest rate is generally tied (positively or negatively) to the price of some commodity, currency, securities index, interest rate, or other economic factor (each, a benchmark). For some hybrids, the principal amount payable at maturity or the interest rate may be increased or decreased, depending on changes in the value of the benchmark. Other hybrids do not bear interest or pay dividends. The value of a hybrid or its interest rate may be a multiple of a benchmark and, as a result, may be leveraged and move (up or down) more steeply and rapidly than the benchmark, thus magnifying movements within the benchmark. These benchmarks may be sensitive to economic and political events, such as commodity shortages and currency devaluations, which cannot be readily foreseen by the purchaser of a hybrid. Under certain conditions, the redemption value of a hybrid could be zero. Thus, an investment in a hybrid may entail significant market risks that are not associated with a similar investment in a traditional, U.S. dollar-denominated bond with a fixed principal amount that pays a fixed rate or floating rate of interest. The purchase of hybrids also exposes a fund to the credit risk of the issuer of the hybrids. Depending on the level of a fund’s investment in hybrids, these risks may cause significant fluctuations in the fund’s net asset value. Hybrid instruments may also carry liquidity risk since the instruments are often “customized” to meet the needs of an issuer or, sometimes, the portfolio needs of a particular investor, and therefore the number of investors that are willing and able to buy such instruments in the secondary market may be smaller than that for more traditional debt securities.

Certain issuers of hybrid instruments known as structured products may be deemed to be investment companies as defined in the 1940 Act. As a result, the funds’ investments in these products may be subject to the limitations described under the heading “ Other Investment Companies .”

Interfund Borrowing and Lending. The SEC has granted an exemption permitting registered open-end Vanguard funds to participate in Vanguard’s interfund lending program. This program allows the Vanguard funds to borrow money from and lend money to each other for temporary or emergency purposes. The program is subject to a number of conditions, including, among other things, the requirements that (1) no fund may borrow or lend money through the program unless it receives a more favorable interest rate than is typically available from a bank for a comparable transaction, (2) no fund may lend money if the loan would cause its aggregate outstanding loans through the program to exceed 15% of its net assets at the time of the loan, and (3) a fund’s interfund loans to any one fund shall not exceed 5% of the lending fund’s net assets. In addition, a Vanguard fund may participate in the program only if and to the extent that such participation is consistent with the fund’s investment objective and investment policies. The boards of trustees of the Vanguard funds are responsible for overseeing the interfund lending program. Any delay in repayment to a lending fund could result in a lost investment opportunity or additional borrowing costs.

Investing for Control. Each Vanguard fund invests in securities and other instruments for the sole purpose of achieving a specific investment objective. As such, a Vanguard fund does not seek to acquire, individually or collectively with any other Vanguard fund, enough of a company’s outstanding voting stock to have control over management decisions. A Vanguard fund does not invest for the purpose of controlling a company’s management.

Loan Interests and Direct Debt Instruments. Loan interests and direct debt instruments are interests in amounts owed by a corporate, governmental, or other borrower to lenders or lending syndicates (in the case of loans and loan participations); to suppliers of goods or services (in the case of trade claims or other receivables); or to other parties. These investments involve a risk of loss in case of the default, the insolvency, or the bankruptcy of the borrower and may offer less legal protection to the purchaser in the event of fraud or misrepresentation, or there may be a requirement that a purchaser supply additional cash to a borrower on demand.

Purchasers of loans and other forms of direct indebtedness depend primarily upon the creditworthiness of the borrower for payment of interest and repayment of principal. Direct debt instruments may not be rated by a rating agency. If scheduled interest or principal payments are not made, or are not made in a timely manner, the value of the instrument may be adversely affected. Loans that are fully secured provide more protections than unsecured loans in the event of failure to make scheduled interest or principal payments. However, there is no assurance that the liquidation of collateral from a secured loan would satisfy the borrower’s obligation or that the collateral could be liquidated. Indebtedness of borrowers whose creditworthiness is poor involves substantially greater risks and may be highly speculative. Borrowers that are in bankruptcy or restructuring may never pay off their indebtedness, or they may pay only a small fraction of the

B-20


 

amount owed. Direct indebtedness of developing countries also involves a risk that the governmental entities responsible for the repayment of the debt may be unable, or unwilling, to pay interest and repay principal when due.

Corporate loans and other forms of direct corporate indebtedness in which a fund may invest generally are made to finance internal growth, mergers, acquisitions, stock repurchases, refinancing of existing debt, leveraged buyouts, and other corporate activities. A significant portion of the corporate indebtedness purchased by a fund may represent interests in loans or debt made to finance highly leveraged corporate acquisitions (known as “leveraged buyout” transactions), leveraged recapitalization loans, and other types of acquisition financing. Another portion may also represent loans incurred in restructuring or “work-out” scenarios, including super-priority debtor-in-possession facilities in bankruptcy and acquisition of assets out of bankruptcy. Loans in restructuring or work-out scenarios may be especially vulnerable to the inherent uncertainties in restructuring processes. In addition, the highly leveraged capital structure of the borrowers in any such transactions, whether in acquisition financing or restructuring, may make such loans especially vulnerable to adverse or unusual economic or market conditions.

Loans and other forms of direct indebtedness generally are subject to restrictions on transfer, and only limited opportunities may exist to sell them in secondary markets. As a result, a fund may be unable to sell loans and other forms of direct indebtedness at a time when it may otherwise be desirable to do so or may be able to sell them only at a price that is less than their fair value.

Investments in loans through direct assignment of a financial institution’s interests with respect to a loan may involve additional risks. For example, if a loan is foreclosed, the purchaser could become part owner of any collateral and would bear the costs and liabilities associated with owning and disposing of the collateral. In addition, it is at least conceivable that, under emerging legal theories of lender liability, a purchaser could be held liable as a co-lender. Direct debt instruments may also involve a risk of insolvency of the lending bank or other intermediary.

A loan is often administered by a bank or other financial institution that acts as agent for all holders. The agent administers the terms of the loan, as specified in the loan agreement. Unless the purchaser has direct recourse against the borrower, the purchaser may have to rely on the agent to apply appropriate credit remedies against a borrower under the terms of the loan or other indebtedness. If assets held by the agent for the benefit of a purchaser were determined to be subject to the claims of the agent’s general creditors, the purchaser might incur certain costs and delays in realizing payment on the loan or loan participation and could suffer a loss of principal and/or interest.

Direct indebtedness may include letters of credit, revolving credit facilities, or other standby financing commitments that obligate purchasers to make additional cash payments on demand. These commitments may have the effect of requiring a purchaser to increase its investment in a borrower when it would not otherwise have done so, even if the borrower’s condition makes it unlikely that the amount will ever be repaid.

A fund’s investment policies will govern the amount of total assets that it may invest in any one issuer or in issuers within the same industry. For purposes of these limitations, a fund generally will treat the borrower as the “issuer” of indebtedness held by the fund. In the case of loan participations in which a bank or other lending institution serves as financial intermediary between a fund and the borrower, if the participation does not shift to the fund the direct debtor-creditor relationship with the borrower, SEC interpretations require the fund, in some circumstances, to treat both the lending bank or other lending institution and the borrower as “issuers” for purposes of the fund’s investment policies. Treating a financial intermediary as an issuer of indebtedness may restrict a fund’s ability to invest in indebtedness related to a single financial intermediary, or a group of intermediaries engaged in the same industry, even if the underlying borrowers represent many different companies and industries.

Money Market Fund Reform. The money market fund reforms adopted by the SEC in July 2014 became effective on October 14, 2016. The reforms impact money market funds differently depending on the types of investors permitted to invest in a fund, the types of securities in which a fund may invest, and the principal investments of a money market fund. The reforms impose new liquidity-related requirements on money market funds (including the potential implementation of liquidity fees and redemption gates). Other changes required by the reforms relate to diversification, disclosure, and stress testing requirements. The imposition and termination of a liquidity fee or redemption gate and/or the provision of financial support by an affiliated person of a money market fund will be reported by a money market fund to the SEC on Form N-CR. A money market fund’s designation as institutional, retail, or government determines whether the fund is required to have a floating net asset value (NAV) or is permitted to have a stable NAV. These changes may have significant adverse effects upon a money market fund’s investment strategy, fees and expenses, portfolio (including the liquidity of investments), and return potential.

Mortgage-Backed Securities. Mortgage-backed securities represent direct or indirect participation in, or are collateralized by and payable from, mortgage loans secured by real property or instruments derived from such loans and may be based on different types of mortgages, including those on residential properties or commercial real estate. Mortgage-backed securities include various types of securities, such as government stripped mortgage-backed securities, adjustable rate mortgage-backed securities, and collateralized mortgage obligations.

Generally, mortgage-backed securities represent partial interests in pools of mortgage loans assembled for sale to investors by various governmental agencies, such as the Government National Mortgage Association (GNMA); by government-related organizations, such as the Federal National Mortgage Association (FNMA) and the Federal Home Loan Mortgage Corporation (FHLMC); and by private issuers, such as commercial banks, savings and loan institutions, and mortgage bankers. The average maturity of pass-through pools of mortgage-backed securities in which a fund may invest varies with the maturities of the underlying mortgage instruments. In addition, a pool’s average maturity may be shortened by unscheduled payments on the underlying mortgages. Factors affecting mortgage prepayments include the level of interest rates, the general economic and social conditions, the location of the mortgaged property, and the age of the mortgage. Because prepayment rates of individual mortgage pools vary widely, the average life of a particular pool cannot be predicted accurately.

Mortgage-backed securities may be classified as private, government, or government-related, depending on the issuer or guarantor. Private mortgage-backed securities represent interest in pass-through pools consisting principally of conventional residential or commercial mortgage loans created by nongovernment issuers, such as commercial banks, savings and loan associations, and private mortgage insurance companies. Private mortgage-backed securities may not be readily marketable. In addition, mortgage-backed securities have been subject to greater liquidity risk because of the deterioration of worldwide economic and liquidity conditions that became especially severe in 2008. U.S. government mortgage-backed securities are backed by the full faith and credit of the U.S. government. GNMA, the principal U.S. guarantor of these securities, is a wholly owned U.S. government corporation within the Department of Housing and Urban Development. Government-related mortgage-backed securities are not backed by the full faith and credit of the U.S. government. Issuers include FNMA and FHLMC, which are congressionally chartered corporations. In September 2008, the U.S. Treasury placed FNMA and FHLMC under conservatorship and appointed the Federal Housing Finance Agency (FHFA) to manage their daily operations. In addition, the U.S. Treasury entered into purchase agreements with FNMA and FHLMC to provide them with capital in exchange for senior preferred stock. Pass-through securities issued by FNMA are guaranteed as to timely payment of principal and interest by FNMA. Participation certificates representing interests in mortgages from FHLMC’s national portfolio are guaranteed as to the timely payment of interest and principal by FHLMC. Private, government, or government-related entities may create mortgage loan pools offering pass-through investments in addition to those described above. The mortgages underlying these securities may be alternative mortgage instruments (i.e., mortgage instruments whose principal or interest payments may vary or whose terms to maturity may be shorter than customary).

Mortgage-backed securities are often subject to more rapid repayment than their stated maturity date would indicate as a result of the pass-through of prepayments of principal on the underlying loans. Prepayments of principal by mortgagors or mortgage foreclosures shorten the term of the mortgage pool underlying the mortgage-backed security. A fund’s ability to maintain positions in mortgage-backed securities is affected by the reductions in the principal amount of such securities resulting from prepayments. A fund’s ability to reinvest prepayments of principal at comparable yield is subject to generally prevailing interest rates at that time. The values of mortgage-backed securities vary with changes in market interest rates generally and the differentials in yields among various kinds of government securities, mortgage-backed securities, and asset-backed securities. In periods of rising interest rates, the rate of prepayment tends to decrease, thereby lengthening the average life of a pool of mortgages supporting a mortgage-backed security. Conversely, in periods of falling interest rates, the rate of prepayment tends to increase, thereby shortening the average life of such a pool. Because prepayments of principal generally occur when interest rates are declining, an investor, such as a fund, generally has to reinvest the proceeds of such prepayments at lower interest rates than those at which its assets were previously invested. Therefore, mortgage-backed securities have less potential for capital appreciation in periods of falling interest rates than other income-bearing securities of comparable maturity.

Mortgage-Backed Securities—Adjustable Rate Mortgage-Backed Securities. Adjustable rate mortgage-backed securities (ARMBSs) have interest rates that reset at periodic intervals. Acquiring ARMBSs permits a fund to participate in increases in prevailing current interest rates through periodic adjustments in the coupons of mortgages underlying the pool on which ARMBSs are based. Such ARMBSs generally have higher current yield and lower price fluctuations than is

B-22


 

the case with more traditional fixed income debt securities of comparable rating and maturity. However, because the interest rates on ARMBSs are reset only periodically, changes in market interest rates or in the issuer’s creditworthiness may affect their value. In addition, when prepayments of principal are made on the underlying mortgages during periods of rising interest rates, a fund can reinvest the proceeds of such prepayments at rates higher than those at which they were previously invested. Mortgages underlying most ARMBSs, however, have limits on the allowable annual or lifetime increases that can be made in the interest rate that the mortgagor pays. Therefore, if current interest rates rise above such limits over the period of the limitation, a fund holding an ARMBS does not benefit from further increases in interest rates. Moreover, when interest rates are in excess of coupon rates (i.e., the rates being paid by mortgagors) of the mortgages, ARMBSs behave more like fixed income securities and less like adjustable rate securities and are thus subject to the risks associated with fixed income securities. In addition, during periods of rising interest rates, increases in the coupon rate of adjustable rate mortgages generally lag current market interest rates slightly, thereby creating the potential for capital depreciation on such securities.

Mortgage-Backed Securities—Collateralized Mortgage Obligations. Collateralized mortgage obligations (CMOs) are mortgage-backed securities that are collateralized by whole loan mortgages or mortgage pass-through securities. The bonds issued in a CMO transaction are divided into groups, and each group of bonds is referred to as a “tranche.” Under the traditional CMO structure, the cash flows generated by the mortgages or mortgage pass-through securities in the collateral pool are used to first pay interest and then pay principal to the CMO bondholders. The bonds issued under a traditional CMO structure are retired sequentially as opposed to the pro-rata return of principal found in traditional pass-through obligations. Subject to the various provisions of individual CMO issues, the cash flow generated by the underlying collateral (to the extent it exceeds the amount required to pay the stated interest) is used to retire the bonds. Under a CMO structure, the repayment of principal among the different tranches is prioritized in accordance with the terms of the particular CMO issuance. The “fastest-pay” tranches of bonds, as specified in the prospectus for the issuance, would initially receive all principal payments. When those tranches of bonds are retired, the next tranche (or tranches) in the sequence, as specified in the prospectus, receives all of the principal payments until that tranche is retired. The sequential retirement of bond groups continues until the last tranche is retired. Accordingly, the CMO structure allows the issuer to use cash flows of long-maturity, monthly pay collateral to formulate securities with short, intermediate, and long final maturities and expected average lives and risk characteristics.

In recent years, new types of CMO tranches have evolved. These include floating rate CMOs, planned amortization classes, accrual bonds, and CMO residuals. These newer structures affect the amount and timing of principal and interest received by each tranche from the underlying collateral. Under certain of these new structures, given classes of CMOs have priority over others with respect to the receipt of prepayments on the mortgages. Therefore, depending on the type of CMOs in which a fund invests, the investment may be subject to a greater or lesser risk of prepayment than other types of mortgage-backed securities.

CMOs may include real estate mortgage investment conduits (REMICs). REMICs, which were authorized under the Tax Reform Act of 1986, are private entities formed for the purpose of holding a fixed pool of mortgages secured by an interest in real property. A REMIC is a CMO that qualifies for special tax treatment under the IRC and invests in certain mortgages principally secured by interests in real property. Investors may purchase beneficial interests in REMICs, which are known as “regular” interests, or “residual” interests. Guaranteed REMIC pass-through certificates (REMIC Certificates) issued by FNMA or FHLMC represent beneficial ownership interests in a REMIC trust consisting principally of mortgage loans or FNMA, FHLMC, or GNMA-guaranteed mortgage pass-through certificates. For FHLMC REMIC Certificates, FHLMC guarantees the timely payment of interest and also guarantees the payment of principal, as payments are required to be made on the underlying mortgage participation certificates. FNMA REMIC Certificates are issued and guaranteed as to timely distribution of principal and interest by FNMA.

The primary risk of CMOs is the uncertainty of the timing of cash flows that results from the rate of prepayments on the underlying mortgages serving as collateral and from the structure of the particular CMO transaction (i.e., the priority of the individual tranches). An increase or decrease in prepayment rates (resulting from a decrease or increase in mortgage interest rates) will affect the yield, the average life, and the price of CMOs. The prices of certain CMOs, depending on their structure and the rate of prepayments, can be volatile. Some CMOs may also not be as liquid as other securities.

Mortgage-Backed Securities—Hybrid ARMs. A hybrid adjustable rate mortgage (hybrid ARM) is a type of mortgage in which the interest rate is fixed for a specified period and then resets periodically, or floats, for the remaining mortgage term. Hybrid ARMs are usually referred to by their fixed and floating periods. For example, a 5/1 ARM refers to a mortgage with a 5-year fixed interest rate period, followed by a 1-year interest rate adjustment period. During the initial

B-23


 

interest period (i.e., the initial five years for a 5/1 hybrid ARM), hybrid ARMs behave more like fixed income securities and are thus subject to the risks associated with fixed income securities. All hybrid ARMs have reset dates. A reset date is the date when a hybrid ARM changes from a fixed interest rate to a floating interest rate. At the reset date, a hybrid ARM can adjust by a maximum specified amount based on a margin over an identified index. Like ARMBSs, hybrid ARMs have periodic and lifetime limitations on the increases that can be made to the interest rates that mortgagors pay. Therefore, if during a floating rate period interest rates rise above the interest rate limits of the hybrid ARM, a fund holding the hybrid ARM does not benefit from further increases in interest rates.

Mortgage-Backed Securities—Mortgage Dollar Rolls. A mortgage dollar roll is a transaction in which a fund sells a mortgage-backed security to a dealer and simultaneously agrees to purchase a similar security (but not the same security) in the future at a predetermined price. A mortgage-dollar-roll program may be structured to simulate an investment in mortgage-backed securities at a potentially lower cost, or with potentially reduced administrative burdens, than directly holding mortgage-backed securities. For accounting purposes, each transaction in a mortgage dollar roll is viewed as a separate purchase and sale of a mortgage-backed security. These transactions may increase a fund’s portfolio turnover rate. The fund receives cash for a mortgage-backed security in the initial transaction and enters into an agreement that requires the fund to purchase a similar mortgage-backed security in the future.

The counterparty with which a fund enters into a mortgage-dollar-roll transaction is obligated to provide the fund with similar securities to purchase as those originally sold by the fund. These securities generally must (1) be issued by the same agency and be part of the same program; (2) have similar original stated maturities; (3) have identical net coupon rates; and (4) satisfy “good delivery” requirements, meaning that the aggregate principal amounts of the securities delivered and received back must be within a certain percentage of the initial amount delivered. Mortgage dollar rolls will be used only if consistent with a fund’s investment objective and strategies and will not be used to change a fund’s risk profile.

Mortgage-Backed Securities—Stripped Mortgage-Backed Securities. Stripped mortgage-backed securities (SMBSs) are derivative multiclass mortgage-backed securities. SMBSs may be issued by agencies or instrumentalities of the U.S. government or by private originators of, or investors in, mortgage loans, including savings and loan associations, mortgage banks, commercial banks, investment banks, and special purpose entities formed or sponsored by any of the foregoing.

SMBSs are usually structured with two classes that receive different proportions of the interest and principal distributions on a pool of mortgage assets. A common type of SMBS will have one class receiving some of the interest and most of the principal from the mortgage assets, while the other class will receive most of the interest and the remainder of the principal. In the most extreme case, one class will receive all of the interest (the “IO” class), while the other class will receive all of the principal (the principal-only or “PO” class). The price and yield to maturity on an IO class are extremely sensitive to the rate of principal payments (including prepayments) on the related underlying mortgage assets, and a rapid rate of principal payments may have a material adverse effect on a fund’s yield to maturity from these securities. If the underlying mortgage assets experience greater than anticipated prepayments of principal, a fund may fail to recoup some or all of its initial investment in these securities, even if the security is in one of the highest rating categories.

Although SMBSs are purchased and sold by institutional investors through several investment banking firms acting as brokers or dealers, these securities were only recently developed. As a result, established trading markets have not yet developed, and accordingly, these securities may be deemed “illiquid” and thus subject to a fund’s limitations on investment in illiquid securities.

Municipal Bonds . Municipal bonds are debt obligations issued by states, municipalities, U.S. jurisdictions or territories, and other political subdivisions and by agencies, authorities, and instrumentalities of states and multistate agencies or authorities (collectively, municipalities). Typically, the interest payable on municipal bonds is, in the opinion of bond counsel to the issuer at the time of issuance, exempt from federal income tax.

Municipal bonds include securities from a variety of sectors, each of which has unique risks, and can be divided into government bonds (i.e., bonds issued to provide funding for governmental projects, such as public roads or schools) and conduit bonds (i.e., bonds issued to provide funding for a third-party permitted to use municipal bond proceeds, such as airports or hospitals). The Funds will not concentrate in any one industry; tax-exempt securities issued by states, municipalities, and their political subdivisions are not considered to be part of an industry. However, if a municipal bond’s income is derived from a specific project, the securities will be considered to be from the industry of that project. Municipal bonds include, but are not limited to, general obligation bonds, limited obligation bonds, and revenue bonds, including industrial development bonds issued pursuant to federal tax law.

B-24


 

General obligation bonds are secured by the issuer’s pledge of its full faith, credit, and taxing power for the payment of principal and interest. Limited obligation bonds are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise or other specific revenue source. Revenue or special tax bonds are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise or other tax, but not from general tax revenues.

Revenue bonds involve the credit risk of the underlying project or enterprise (or its corporate user) rather than the credit risk of the issuing municipality. Under the IRC, certain limited obligation bonds are considered “private activity bonds,” and interest paid on such bonds is treated as an item of tax preference for purposes of calculating federal alternative minimum tax liability. Tax-exempt private activity bonds and industrial development bonds generally are also classified as revenue bonds and thus are not payable from the issuer’s general revenues. The credit and quality of private activity bonds and industrial development bonds are usually related to the credit of the corporate user of the facilities. Payment of interest on and repayment of principal of such bonds are the responsibility of the corporate user (and/or any guarantor). Some municipal bonds may be issued as variable or floating rate securities and may incorporate market-dependent liquidity features (see discussion of “Debt Securities—Variable and Floating Rate Securities” ). A tax-exempt fund will generally invest only in securities deemed tax-exempt by a nationally recognized bond counsel, but there is no guarantee that the interest payments on municipal bonds will continue to be tax-exempt for the life of the bonds.

Some longer-term municipal bonds give the investor a “put option,” which is the right to sell the security back to the issuer at par (face value) prior to maturity, within a specified number of days following the investor’s request—usually one to seven days. This demand feature enhances a security’s liquidity by shortening its maturity and enables it to trade at a price equal to or very close to par. If a demand feature terminates prior to being exercised, a fund would hold the longer-term security, which could experience substantially more volatility. Municipal bonds that are issued as variable or floating rate securities incorporating market-dependent liquidity features may have greater liquidity risk than other municipal bonds (see discussion of “Debt Securities—Variable and Floating Rate Securities” ).

Some municipal bonds feature credit enhancements, such as lines of credit, letters of credit, municipal bond insurance, and standby bond purchase agreements (SBPAs). SBPAs include lines of credit that are issued by a third party, usually a bank, to enhance liquidity and ensure repayment of principal and any accrued interest if the underlying municipal bond should default. Municipal bond insurance (which is usually purchased by the bond issuer from a private, nongovernmental insurance company) provides an unconditional and irrevocable guarantee that the insured bond’s principal and interest will be paid when due. Insurance does not guarantee the price of the bond or the share price of any fund. The credit quality of an insured bond reflects the higher of the credit quality of the insurer, based on its claims-paying ability, or the credit quality of the underlying bond issuer or obligor. The obligation of a municipal bond insurance company to pay a claim extends over the life of each insured bond. Although defaults on insured municipal bonds have been historically low and municipal bond insurers historically have met their claims, there is no assurance this will continue. A higher-than-expected default rate could strain the insurer’s loss reserves and adversely affect its ability to pay claims to bondholders. The number of municipal bond insurers is relatively small, and not all of them are assessed as high credit quality. An SBPA can include a liquidity facility that is provided to pay the purchase price of any bonds that cannot be remarketed. The obligation of the liquidity provider (usually a bank) is only to advance funds to purchase tendered bonds that cannot be remarketed and does not cover principal or interest under any other circumstances. The liquidity provider’s obligations under the SBPA are usually subject to numerous conditions, including the continued creditworthiness of the underlying borrower or bond issuer.

Municipal bonds also include tender option bonds, which are municipal derivatives created by dividing the income stream provided by an underlying municipal bond to create two securities issued by a special-purpose trust, one short-term and one long-term. The interest rate on the short-term component is periodically reset. The short-term component has negligible interest rate risk, while the long-term component has all of the interest rate risk of the original bond. After income is paid on the short-term securities at current rates, the residual income goes to the long-term securities. Therefore, rising short-term interest rates result in lower income for the longer-term portion, and vice versa. The longer-term components can be very volatile and may be less liquid than other municipal bonds of comparable maturity. These securities have been developed in the secondary market to meet the demand for short-term, tax-exempt securities.

Municipal securities also include a variety of structures geared toward accommodating municipal-issuer short-term cash-flow requirements. These structures include, but are not limited to, general market notes, commercial paper, put bonds, and variable-rate demand obligations (VRDOs). VRDOs comprise a significant percentage of the outstanding debt in the short-term municipal market. VRDOs can be structured to provide a wide range of maturity options (1 day to over 360

B-25


 

days) to the underlying issuing entity and are typically issued at par. The longer the maturity option, the greater the degree of liquidity risk (the risk of not receiving an asking price of par or greater) and reinvestment risk (the risk that the proceeds from maturing bonds must be reinvested at a lower interest rate).

Although most municipal bonds are exempt from federal income tax, some are not. Taxable municipal bonds include Build America Bonds (BABs). The borrowing costs of BABs are subsidized by the federal government, but BABs are subject to state and federal income tax. BABs were created pursuant to the American Recovery and Reinvestment Act of 2009 (ARRA) to offer an alternative form of financing to state and local governments whose primary means for accessing the capital markets had been through the issuance of tax-exempt municipal bonds. BABs also include Recovery Zone Economic Development Bonds, which are subsidized more heavily by the federal government than other BABs and are designed to finance certain types of projects in distressed geographic areas.

Under ARRA, an issuer of a BAB is entitled to receive payments from the U.S. Treasury over the life of the BAB equal to 35% of the interest paid (or 45% of the interest paid in the case of a Recovery Zone Economic Development Bond). For example, if a state or local government were to issue a BAB at a taxable interest rate of 10% of the par value of the bond, the U.S. Treasury would make a payment directly to the issuing government of 35% of that interest (3.5% of the par value of the bond) or 45% of the interest (4.5% of the par value of the bond) in the case of a Recovery Zone Economic Development Bond. Thus, the state or local government’s net borrowing cost would be 6.5% or 5.5%, respectively, on BABs that pay 10% interest. In other cases, holders of a BAB receive a 35% or 45% tax credit, respectively. The BAB program expired on December 31, 2010. BABs outstanding prior to the expiration of the program continue to be eligible for the federal interest rate subsidy or tax credit, which continues for the life of the BABs; however, the federal interest rate subsidy or tax credit has been reduced by the government sequester. Additionally, bonds issued following expiration of the program are not eligible for federal payment or tax credit. In addition to BABs, a fund may invest in other municipal bonds that pay taxable interest.

The reorganization under the federal bankruptcy laws of an issuer of, or payment obligor with respect to, municipal bonds may result in the municipal bonds being canceled without repayment; repaid only in part; or repaid in part or whole through an exchange thereof for any combination of cash, municipal bonds, debt securities, convertible securities, equity securities, or other instruments or rights in respect to the same issuer or payment obligor or a related entity. Certain issuers are not eligible to file for bankruptcy.

Municipal Bonds—Risks . Municipal bonds are subject to credit risk. The yields of municipal bonds depend on, among other things, general money market conditions, conditions in the municipal bond market, size of a particular offering, maturity of the obligation, and credit quality of the issue. Consequently, municipal bonds with the same maturity, coupon, and credit quality may have different yields, while municipal bonds of the same maturity and coupon, but with different credit quality, may have the same yield. It is the responsibility of a fund’s investment management advisor to appraise independently the fundamental quality of bonds held by the fund. Information about the financial condition of an issuer of municipal bonds may not be as extensive as that which is made available by corporations whose securities are publicly traded. Obligations of issuers of municipal bonds are generally subject to the provisions of bankruptcy, insolvency, and other laws affecting the rights and remedies of creditors.

Congress, state legislatures, or other governing authorities may seek to extend the time for payment of principal or interest, or both, or to impose other constraints upon enforcement of such obligations. For example, from time to time, proposals have been introduced before Congress to restrict or eliminate the federal income tax exemption for interest on municipal bonds. Also, from time to time, proposals have been introduced before state and local legislatures to restrict or eliminate the state and local income tax exemption for interest on municipal bonds. Similar proposals may be introduced in the future. If any such proposal were enacted, it might restrict or eliminate the ability of a fund to achieve its respective investment objective. In that event, the fund’s trustees and officers would reevaluate its investment objective and policies and consider recommending to its shareholders changes in such objective and policies.

There is also the possibility that, as a result of litigation or other conditions, the power or ability of issuers to meet their obligations for the payment of interest and principal on their municipal bonds may be materially affected or their obligations may be found to be invalid or unenforceable. Such litigation or conditions may, from time to time, have the effect of introducing uncertainties in the market for municipal bonds or certain segments thereof or of materially affecting the credit risk with respect to particular bonds. Adverse economic, business, legal, or political developments might affect all or a substantial portion of a fund’s municipal bonds in the same manner. For example, a state specific tax-exempt fund is subject to state-specific risk, which is the chance that the fund, because it invests primarily in securities

B-26


 

issued by a particular state and its municipalities, is more vulnerable to unfavorable developments in that state than are funds that invest in municipal securities of many states. Unfavorable developments in any economic sector may have far-reaching ramifications on a state’s overall municipal market. In the event that a particular obligation held by a fund is assessed at a credit quality below the minimum investment level permitted by the investment policies of such fund, the fund’s investment advisor, pursuant to oversight from the trustees, will carefully assess the creditworthiness of the obligation to determine whether it continues to meet the policies and objective of the fund.

Municipal bonds are subject to interest rate risk, which is the chance that bond prices will decline over short or even long periods because of rising interest rates. Interest rate risk is higher for long-term bonds, whose prices are much more sensitive to interest rate changes than are the prices of shorter-term bonds. Generally, prices of longer-maturity issues tend to fluctuate more than prices of shorter-maturity issues. Prices and yields on municipal bonds are dependent on a variety of factors, such as the financial condition of the issuer, the general conditions of the municipal bond market, the size of a particular offering, the maturity of the obligation, and the rating of the issue. A number of these factors, including the ratings of particular issues, are subject to change from time to time.

Municipal bonds are 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. A 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. Call risk is generally high for long-term bonds. Conversely, municipal bonds are also subject to extension risk, which is the chance that during periods of rising interest rates, certain debt securities will be paid off substantially more slowly than originally anticipated, and the value of those securities may fall. Extension risk is generally high for long-term bonds.

Municipal bonds may be deemed to be illiquid as determined by or in accordance with methods adopted by a fund’s board of trustees. In determining the liquidity and appropriate valuation of a municipal bond, a fund’s advisor may consider the following factors relating to the security, among others: (1) the frequency of trades and quotes; (2) the number of dealers willing to purchase or sell the security; (3) the willingness of dealers to undertake to make a market; (4) the nature of the marketplace trades, including the time needed to dispose of the security, the method of soliciting offers, and the mechanics of transfer; and (5) the factors unique to a particular security, including general creditworthiness of the issuer and the likelihood that the marketability of the securities will be maintained throughout the time the security is held by the fund.

Options. An option is a derivative. An option on a security (or index) is a contract that gives the holder of the option, in return for the payment of a “premium,” the right, but not the obligation, to buy from (in the case of a call option) or sell to (in the case of a put option) the writer of the option the security underlying the option (or the cash value of the index) at a specified exercise price prior to the expiration date of the option. The writer of an option on a security has the obligation upon exercise of the option to deliver the underlying security upon payment of the exercise price (in the case of a call option) or to pay the exercise price upon delivery of the underlying security (in the case of a put option). The writer of an option on an index has the obligation upon exercise of the option to pay an amount equal to the cash value of the index minus the exercise price, multiplied by the specified multiplier for the index option. The multiplier for an index option determines the size of the investment position the option represents. Unlike exchange-traded options, which are standardized with respect to the underlying instrument, expiration date, contract size, and strike price, the terms of over-the-counter (OTC) options (options not traded on exchanges) generally are established through negotiation with the other party to the option contract. Although this type of arrangement allows the purchaser or writer greater flexibility to tailor an option to its needs, OTC options generally involve credit risk to the counterparty whereas for exchange-traded, centrally cleared options, credit risk is mutualized through the involvement of the applicable clearing house.

The buyer (or holder) of an option is said to be “long” the option, while the seller (or writer) of an option is said to be “short” the option. A call option grants to the holder the right to buy (and obligates the writer to sell) the underlying security at the strike price, which is the predetermined price at which the option may be exercised. A put option grants to the holder the right to sell (and obligates the writer to buy) the underlying security at the strike price. The purchase price of an option is called the “premium.” The potential loss to an option buyer is limited to the amount of the premium plus transaction costs. This will be the case if the option is held and not exercised prior to its expiration date. Generally, an option writer sells options with the goal of obtaining the premium paid by the option buyer, but that person could also seek to profit from an anticipated rise or decline in option prices. If an option sold by an option writer expires without being exercised, the writer retains the full amount of the premium. The option writer, however, has unlimited economic

B-27


 

risk because its potential loss, except to the extent offset by the premium received when the option was written, is equal to the amount the option is “in-the-money” at the expiration date. A call option is in-the-money if the value of the underlying position exceeds the exercise price of the option. A put option is in-the-money if the exercise price of the option exceeds the value of the underlying position. Generally, any profit realized by an option buyer represents a loss for the option writer. The writing of an option will not be considered to constitute the issuance, by a fund, of a “senior security,” as that term is defined in Section 18(g) of the 1940 Act, and therefore such transaction will not be subject to the 300% asset coverage requirement otherwise applicable to borrowings by a fund, if the fund covers the transaction in accordance with the requirements described under the heading “ Borrowing .”

If a trading market, in particular options, were to become unavailable, investors in those options (such as the funds) would be unable to close out their positions until trading resumes, and they may be faced with substantial losses if the value of the underlying instrument moves adversely during that time. Even if the market were to remain available, there may be times when options prices will not maintain their customary or anticipated relationships to the prices of the underlying instruments and related instruments. Lack of investor interest, changes in volatility, or other factors or conditions might adversely affect the liquidity, efficiency, continuity, or even the orderliness of the market for particular options.

A fund bears the risk that its advisor will not accurately predict future market trends. If the advisor attempts to use an option as a hedge against, or as a substitute for, a portfolio investment, the fund will be exposed to the risk that the option will have or will develop imperfect or no correlation with the portfolio investment, which could cause substantial losses for the fund. Although hedging strategies involving options can reduce the risk of loss, they can also reduce the opportunity for gain or even result in losses by offsetting favorable price movements in other fund investments. Many options, in particular OTC options, are complex and often valued based on subjective factors. Improper valuations can result in increased cash payment requirements to counterparties or a loss of value to a fund.

OTC Swap Agreements. An over-the-counter (OTC) swap agreement, which is a type of derivative, is an agreement between two parties (counterparties) to exchange payments at specified dates (periodic payment dates) on the basis of a specified amount (notional amount) with the payments calculated with reference to a specified asset, reference rate, or index.

Examples of OTC swap agreements include, but are not limited to, interest rate swaps, credit default swaps, equity swaps, commodity swaps, foreign currency swaps, index swaps, excess return swaps, and total return swaps. Most OTC swap agreements provide that when the periodic payment dates for both parties are the same, payments are netted and only the net amount is paid to the counterparty entitled to receive the net payment. Consequently, a fund’s current obligations (or rights) under an OTC swap agreement will generally be equal only to the net amount to be paid or received under the agreement, based on the relative values of the positions held by each counterparty. OTC swap agreements allow for a wide variety of transactions. For example, fixed rate payments may be exchanged for floating rate payments; U.S. dollar-denominated payments may be exchanged for payments denominated in a different currency; and payments tied to the price of one asset, reference rate, or index may be exchanged for payments tied to the price of another asset, reference rate, or index.

An OTC option on an OTC swap agreement, also called a “swaption,” is an option that gives the buyer the right, but not the obligation, to enter into a swap on a future date in exchange for paying a market-based “premium.” A receiver swaption gives the owner the right to receive the total return of a specified asset, reference rate, or index. A payer swaption gives the owner the right to pay the total return of a specified asset, reference rate, or index. Swaptions also include options that allow an existing swap to be terminated or extended by one of the counterparties.

The use of OTC swap agreements by a fund entails certain risks, which may be different from, or possibly greater than, the risks associated with investing directly in the securities and other investments that are the referenced asset for the swap agreement. OTC swaps are highly specialized instruments that require investment techniques, risk analyses, and tax planning different from those associated with stocks, bonds, and other traditional investments. The use of an OTC swap requires an understanding not only of the referenced asset, reference rate, or index but also of the swap itself, without the benefit of observing the performance of the swap under all possible market conditions.

OTC swap agreements may be subject to liquidity risk, which exists when a particular swap is difficult to purchase or sell. If an OTC swap transaction is particularly large or if the relevant market is illiquid (as is the case with many OTC swaps), it may not be possible to initiate a transaction or liquidate a position at an advantageous time or price, which may result in significant losses. In addition, OTC swap transactions may be subject to a fund’s limitation on investments in illiquid securities.

B-28


 

OTC swap agreements may be subject to pricing risk, which exists when a particular swap becomes extraordinarily expensive or inexpensive relative to historical prices or the prices of corresponding cash market instruments. Under certain market conditions, it may not be economically feasible to initiate a transaction or liquidate a position in time to avoid a loss or take advantage of an opportunity or to realize the intrinsic value of the OTC swap agreement.

Because certain OTC swap agreements have a leverage component, adverse changes in the value or level of the underlying asset, reference rate, or index can result in a loss substantially greater than the amount invested in the swap itself. Certain OTC swaps have the potential for unlimited loss, regardless of the size of the initial investment. A leveraged OTC swap transaction will not be considered to constitute the issuance, by a fund, of a “senior security,” as that term is defined in Section 18(g) of the 1940 Act, and therefore such transaction will not be subject to the 300% asset coverage requirement otherwise applicable to borrowings by a fund, if the fund covers the transaction in accordance with the requirements described under the heading “Borrowing.”

Like most other investments, OTC swap agreements are subject to the risk that the market value of the instrument will change in a way detrimental to a fund’s interest. A fund bears the risk that its advisor will not accurately forecast future market trends or the values of assets, reference rates, indexes, or other economic factors in establishing OTC swap positions for the fund. If the advisor attempts to use an OTC swap as a hedge against, or as a substitute for, a portfolio investment, the fund will be exposed to the risk that the OTC swap will have or will develop imperfect or no correlation with the portfolio investment. This could cause substantial losses for the fund. Although hedging strategies involving OTC swap instruments can reduce the risk of loss, they can also reduce the opportunity for gain or even result in losses by offsetting favorable price movements in other fund investments. Many OTC swaps are complex and often valued subjectively. Improper valuations can result in increased cash payment requirements to counterparties or a loss of value to a fund.

The use of an OTC swap agreement also involves the risk that a loss may be sustained as a result of the insolvency or bankruptcy of the counterparty or the failure of the counterparty to make required payments or otherwise comply with the terms of the agreement. Additionally, the use of credit default swaps can result in losses if a fund’s advisor does not correctly evaluate the creditworthiness of the issuer on which the credit swap is based.

The market for OTC swaps and swaptions is a relatively new market. It is possible that developments in the market could adversely affect a fund, including its ability to terminate existing OTC swap agreements or to realize amounts to be received under such agreements. As previously noted under the heading “Derivatives,” under the Dodd-Frank Act, certain swaps that may be used by a fund may be cleared through a clearinghouse and traded on an exchange or swap execution facility.

Other Investment Companies . A fund may invest in other investment companies to the extent permitted by applicable law or SEC exemption. Under Section 12(d)(1) of the 1940 Act, a fund generally may invest up to 10% of its assets in shares of investment companies and up to 5% of its assets in any one investment company, as long as no investment represents more than 3% of the voting stock of an acquired investment company. In addition, no funds for which Vanguard acts as an advisor may, in the aggregate, own more than 10% of the voting stock of a closed-end investment company. The 1940 Act and related rules provide certain exemptions from these restrictions, for example, for funds that invest in other funds within the same group of investment companies. If a fund invests in other investment companies, shareholders will bear not only their proportionate share of the fund’s expenses (including operating expenses and the fees of the advisor), but they also may indirectly bear similar expenses of the underlying investment companies. Certain investment companies, such as business development companies (BDCs), are more akin to operating companies and, as such, their expenses are not direct expenses paid by fund shareholders and are not used to calculate the fund’s net asset value. SEC rules nevertheless require that any expenses incurred by a BDC be included in a fund’s expense ratio as “Acquired Fund Fees and Expenses.” The expense ratio of a fund that holds a BDC will thus overstate what the fund actually spends on portfolio management, administrative services, and other shareholder services by an amount equal to these Acquired Fund Fees and Expenses. The Acquired Fund Fees and Expenses are not included in a fund’s financial statements, which provide a clearer picture of a fund’s actual operating expenses. Shareholders would also be exposed to the risks associated not only with the investments of the fund but also with the portfolio investments of the underlying investment companies. Certain types of investment companies, such as closed-end investment companies, issue a fixed number of shares that typically trade on a stock exchange or over-the-counter at a premium or discount to their net asset value. Others are continuously offered at net asset value but also may be traded on the secondary market.

Preferred Stock. Preferred stock represents an equity or ownership interest in an issuer. Preferred stock normally pays dividends at a specified rate and has precedence over common stock in the event the issuer is liquidated or declares bankruptcy. However, in the event an issuer is liquidated or declares bankruptcy, the claims of owners of bonds take precedence over the claims of those who own preferred and common stock. Preferred stock, unlike common stock, often has a stated dividend rate payable from the corporation’s earnings. Preferred stock dividends may be cumulative or noncumulative, participating, or auction rate. “Cumulative” dividend provisions require all or a portion of prior unpaid dividends to be paid before dividends can be paid to the issuer’s common stock. “Participating” preferred stock may be entitled to a dividend exceeding the stated dividend in certain cases. If interest rates rise, the fixed dividend on preferred stocks may be less attractive, causing the price of such stocks to decline. Preferred stock may have mandatory sinking fund provisions, as well as provisions allowing the stock to be called or redeemed, which can limit the benefit of a decline in interest rates. Preferred stock is subject to many of the risks to which common stock and debt securities are subject. In addition, preferred stock may be subject to more abrupt or erratic price movements than common stock or debt securities because preferred stock may trade with less frequency and in more limited volume.

Private Equity. Private equity is equity capital that is not quoted on a public exchange. It consists of investors and funds that make investments directly into private companies or conduct buyouts of public companies that result in a delisting of public equity. Capital for private equity is raised from retail and institutional investors, and can be used to fund new technologies, expand working capital within an owned company, make acquisitions, or to strengthen a balance sheet. Private equity securities should be regarded as illiquid, as they are not listed on an exchange and are generally not transferable. By their nature, investments in privately held companies tend to be riskier than investments in publicly traded companies. Generally, there will be no readily available market for private equity investments and, accordingly, most such investments are difficult to value and can be difficult to exit.

Real Estate Investment Trusts (REITs) . An equity REIT owns real estate properties directly and generates income from rental and lease payments. Equity REITs also have the potential to generate capital gains as properties are sold at a profit. A mortgage REIT makes construction, development, and long-term mortgage loans to commercial real estate developers and earns interest income on these loans. A hybrid REIT holds both properties and mortgages. To avoid taxation at the corporate level, REITs must distribute most of their earnings to shareholders.

Investments in REITs are subject to many of the same risks as direct investments in real estate. In general, real estate values can be affected by a variety of factors, including, but not limited to, supply and demand for properties, general or local economic conditions, and the strength of specific industries that rent properties. Ultimately, a REIT’s performance depends on the types and locations of the properties it owns and on how well the REIT manages its properties. For example, rental income could decline because of extended vacancies, increased competition from nearby properties, tenants’ failure to pay rent, regulatory limitations on rents, fluctuations in rental income, variations in market rental rates, or incompetent management. Property values could decrease because of overbuilding in the area, environmental liabilities, uninsured damages caused by natural disasters, a general decline in the neighborhood, losses because of casualty or condemnation, increases in property taxes, or changes in zoning laws.

The value of a REIT may also be affected by changes in interest rates. Rising interest rates generally increase the cost of financing for real estate projects, which could cause the value of an equity REIT to decline. During periods of declining interest rates, mortgagors may elect to prepay mortgages held by mortgage REITs, which could lower or diminish the yield on the REIT. REITs are also subject to heavy cash-flow dependency, default by borrowers, and changes in tax and regulatory requirements. In addition, a REIT may fail to meet the requirements for qualification and taxation as a REIT under the IRC and/or fail to maintain exemption from the 1940 Act.

Repurchase Agreements. A repurchase agreement is an agreement under which a fund acquires a debt security (generally a security issued by the U.S. government or an agency thereof, a banker’s acceptance, or a certificate of deposit) from a bank, a broker, or a dealer and simultaneously agrees to resell such security to the seller at an agreed-upon price and date (normally, the next business day). Because the security purchased constitutes collateral for the repurchase obligation, a repurchase agreement may be considered a loan that is collateralized by the security purchased. The resale price reflects an agreed-upon interest rate effective for the period the instrument is held by a fund and is unrelated to the interest rate on the underlying instrument. In these transactions, the securities acquired by a fund (including accrued interest earned thereon) must have a total value in excess of the value of the repurchase agreement and be held by a custodian bank until repurchased. When entering into a repurchase agreement with the Federal Reserve, the collateral received will equal 100% of the value of the repurchase agreement. In addition, the investment advisor will monitor a fund’s repurchase agreement transactions generally and will evaluate the creditworthiness of any

B-30


 

bank, broker, or dealer party to a repurchase agreement relating to a fund. The aggregate amount of any such agreements is not limited, except to the extent required by law.

The use of repurchase agreements involves certain risks. One risk is the seller’s ability to pay the agreed-upon repurchase price on the repurchase date. If the seller defaults, the fund may incur costs in disposing of the collateral, which would reduce the amount realized thereon. If the seller seeks relief under bankruptcy laws, the disposition of the collateral may be delayed or limited. For example, if the other party to the agreement becomes insolvent and subject to liquidation or reorganization under bankruptcy or other laws, a court may determine that the underlying security is collateral for a loan by the fund not within its control, and therefore the realization by the fund on such collateral may be automatically stayed. Finally, it is possible that the fund may not be able to substantiate its interest in the underlying security and may be deemed an unsecured creditor of the other party to the agreement.

Restricted and Illiquid Securities. Illiquid securities are securities that cannot be sold or disposed of within seven days in the ordinary course of business at approximately the price at which they are valued. The SEC generally limits aggregate holdings of illiquid securities by a mutual fund to 15% of its net assets (5% for money market funds). A fund may experience difficulty valuing and selling illiquid securities and, in some cases, may be unable to value or sell certain illiquid securities for an indefinite period of time. Illiquid securities may include a wide variety of investments, such as (1) repurchase agreements maturing in more than seven days (unless the agreements have demand/redemption features), (2) OTC options contracts and certain other derivatives (including certain swap agreements), (3) fixed time deposits that are not subject to prepayment or do not provide for withdrawal penalties upon prepayment (other than overnight deposits), (4) certain loan interests and other direct debt instruments, (5) certain municipal lease obligations, (6) private equity investments, (7) commercial paper issued pursuant to Section 4(a)(2) of the 1933 Act, and (8) securities whose disposition is restricted under the federal securities laws. Illiquid securities include restricted, privately placed securities that, under the federal securities laws, generally may be resold only to qualified institutional buyers. If a substantial market develops for a restricted security held by a fund, it may be treated as a liquid security in accordance with procedures and guidelines approved by the board of trustees. This generally includes securities that are unregistered, that can be sold to qualified institutional buyers in accordance with Rule 144A under the 1933 Act, or that are exempt from registration under the 1933 Act, such as commercial paper. Although a fund’s advisor monitors the liquidity of restricted securities, the board of trustees oversees and retains ultimate responsibility for the advisor’s liquidity determinations. Several factors that the trustees consider in monitoring these decisions include the valuation of a security; the availability of qualified institutional buyers, brokers, and dealers that trade in the security; and the availability of information about the security’s issuer.

Reverse Repurchase Agreements. In a reverse repurchase agreement, a fund sells a security to another party, such as a bank or broker-dealer, in return for cash and agrees to repurchase that security at an agreed-upon price and time. Under a reverse repurchase agreement, the fund continues to receive any principal and interest payments on the underlying security during the term of the agreement. Reverse repurchase agreements involve the risk that the market value of securities retained by the fund may decline below the repurchase price of the securities sold by the fund that it is obligated to repurchase. In addition to the risk of such a loss, fees charged to the fund may exceed the return the fund earns from investing the proceeds received from the reverse repurchase agreement transaction. A reverse repurchase agreement may be considered a borrowing transaction for purposes of the 1940 Act. A reverse repurchase agreement transaction will not be considered to constitute the issuance, by a fund, of a “senior security,” as that term is defined in Section 18(g) of the 1940 Act, and therefore such transaction will not be subject to the 300% asset coverage requirement otherwise applicable to borrowings by a fund, if the fund covers the transaction in accordance with the requirements described under the heading “Borrowing.” A fund will enter into reverse repurchase agreements only with parties whose creditworthiness has been reviewed and found satisfactory by the advisor. If the buyer in a reverse repurchase agreement becomes insolvent or files for bankruptcy, a fund’s use of proceeds from the sale may be restricted while the other party or its trustee or receiver determines if it will honor the fund’s right to repurchase the securities. If the fund is unable to recover the securities it sold in a reverse repurchase agreement, it would realize a loss equal to the difference between the value of the securities and the payment it received for them.

Securities Lending. A fund may lend its investment securities to qualified institutional investors (typically brokers, dealers, banks, or other financial institutions) who may need to borrow securities in order to complete certain transactions, such as covering short sales, avoiding failures to deliver securities, or completing arbitrage operations. By lending its investment securities, a fund attempts to increase its net investment income through the receipt of interest on the securities lent. Any gain or loss in the market price of the securities lent that might occur during the term of the

B-31


 

loan would be for the account of the fund. If the borrower defaults on its obligation to return the securities lent because of insolvency or other reasons, a fund could experience delays and costs in recovering the securities lent or in gaining access to the collateral. These delays and costs could be greater for foreign securities. If a fund is not able to recover the securities lent, the fund may sell the collateral and purchase a replacement investment in the market. The value of the collateral could decrease below the value of the replacement investment by the time the replacement investment is purchased. Cash received as collateral through loan transactions may be invested in other eligible securities. Investing this cash subjects that investment to market appreciation or depreciation. Currently, Vanguard funds that lend securities invest the cash collateral received in one or more Vanguard CMT Funds, which are very low-cost money market funds.

The terms and the structure of the loan arrangements, as well as the aggregate amount of securities loans, must be consistent with the 1940 Act and the rules or interpretations of the SEC thereunder. These provisions limit the amount of securities a fund may lend to 33 1/3% of the fund’s total assets and require that (1) the borrower pledge and maintain with the fund collateral consisting of cash, an irrevocable letter of credit, or securities issued or guaranteed by the U.S. government having at all times not less than 100% of the value of the securities lent; (2) the borrower add to such collateral whenever the price of the securities lent rises (i.e., the borrower “marks to market” on a daily basis); (3) the loan be made subject to termination by the fund at any time; and (4) the fund receives reasonable interest on the loan (which may include the fund investing any cash collateral in interest-bearing short-term investments), any distribution on the lent securities, and any increase in their market value. Loan arrangements made by a fund will comply with all other applicable regulatory requirements, including the requirement to redeliver the securities within the standard settlement time applicable to the relevant trading market. The advisor will consider the creditworthiness of the borrower, among other things, in making decisions with respect to the lending of securities, subject to oversight by the board of trustees. At the present time, the SEC does not object if an investment company pays reasonable negotiated fees in connection with lent securities, so long as such fees are set forth in a written contract and approved by the investment company’s trustees. In addition, voting rights pass with the lent securities, but if a fund has knowledge that a material event will occur affecting securities on loan, and in respect to which the holder of the securities will be entitled to vote or consent, the lender must be entitled to call the loaned securities in time to vote or consent. A fund bears the risk that there may be a delay in the return of the securities, which may impair the fund’s ability to vote on such a matter.

Pursuant to Vanguard’s securities lending policy, Vanguard’s fixed income and money market funds are not permitted to, and do not, lend their investment securities.

Tax Matters—Federal Tax Discussion Applicable to Variable Annuity and Variable Life Insurance Contracts.

Discussion herein of U.S. federal income tax matters summarizes some of the important, generally applicable U.S. federal tax considerations relevant to the Portfolios and the insurance company separate accounts investing in the Portfolios in the IRC, U.S. Treasury regulations, and other applicable authority. These authorities are subject to change by legislative, administrative, or judicial action, possibly with retroactive effect. The discussion assumes that the shares of each Portfolio will be respected as owned by the insurance company separate accounts that invest in such Portfolio to fund the insurance company’s obligations under a variable life or variable annuity contract. If the IRS were to determine that contract holders have an impermissible level of control over the investments funding their contracts and thus treat the holders as the owners of the shares of a Portfolio, your contract could lose its favorable tax treatment and income and gain allocable to your contract could be taxable to you currently under the applicable federal income tax rules that may not be described herein . For information concerning the federal income tax consequences to a holder of such a contract, refer to the prospectus for the particular contract. A contract holder should consult his or her tax professional for information regarding the particular situation and the possible application of U.S. federal, state, local, foreign, and other taxes. B ecause insurance company separate accounts and other permitted investors are the only shareholders in the Portfolios, only certain tax aspects of an investment in the Portfolios relevant to such shareholders are described herein.

Tax Matters—Federal Tax Treatment of Bonds Issued or Purchased at a Discount. Any investment in zero-coupon bonds, deferred interest bonds, payment-in-kind bonds, certain inflation-adjusted debt instruments, certain stripped securities, and certain securities purchased at a market discount (including certain high yield debt obligations) will cause a Portfolio to recognize income prior to the receipt of cash payments with respect to those securities. To distribute this income and avoid a tax on the Portfolio, the Portfolio may be required to liquidate portfolio securities that it might otherwise have continued to hold.

Tax Matters—Federal Tax Treatment of Derivatives, Foreign Currency, Hedging, and Related Transactions. A

Portfolio’s transactions in derivative instruments (including, but not limited to, options, futures, forward contracts, and

B-32


 

swap agreements), as well as any of the Portfolio’s hedging, short sale, securities loan, or similar transactions, may be subject to one or more special tax rules that accelerate income to the Portfolio, defer losses to the Portfolio, cause adjustments in the holding periods of the Portfolio’s securities, convert long-term capital gains into short-term capital gains, or convert short-term capital losses into long-term capital losses. These rules could therefore affect the amount, timing, and character of distributions to shareholders.

Because these and other tax rules applicable to these types of transactions are in some cases uncertain under current law, an adverse determination or future guidance by the IRS with respect to these rules (which determination or guidance could be retroactive) may affect whether a Portfolio has made sufficient distributions, and otherwise satisfied the relevant requirements, to maintain its qualification as a regulated investment company and avoid a fund-level tax.

Tax Matters—Foreign Tax Credit. Foreign governments may withhold taxes on dividends and interest paid with respect to foreign securities held by a fund. Foreign governments may also impose taxes on other payments or gains with respect to foreign securities. If, at the close of its fiscal year, more than 50% of a fund’s total assets are invested in securities of foreign issuers, the fund may elect to pass through to shareholders the ability to deduct or, if they meet certain holding period requirements, take a credit for foreign taxes paid by the fund. Similarly, if at the close of each quarter of a fund’s taxable year, at least 50% of its total assets consist of interests in other regulated investment companies, the fund is permitted to elect to pass through to its shareholders the foreign income taxes paid by the fund in connection with foreign securities held directly by the fund or held by a regulated investment company in which the fund invests that has elected to pass through such taxes to shareholders.

Tax Matters—Market Discount or Premium. The price of a bond purchased after its original issuance may reflect market discount or premium. Depending on the particular circumstances, market discount may affect the tax character and amount of income required to be recognized by a fund holding the bond. In determining whether a bond is purchased with market discount, certain de minimis rules apply. Premium is generally amortizable over the remaining term of the bond. Depending on the type of bond, premium may affect the amount of income required to be recognized by a fund holding the bond and the fund’s basis in the bond.

Tax Matters—Passive Foreign Investment Companies. Special tax considerations apply with respect to investments by a Portfolio in certain passive foreign investment companies (PFICs). A foreign company is generally a PFIC if 75% or more of its gross income is passive or if 50% or more of its assets produce passive income. Capital gains on the sale of an interest in a PFIC will be deemed ordinary income regardless of how long the Fund held it. Also, each Portfolio may be subject to corporate income tax and an interest charge on certain dividends and capital gains earned in respect to PFICs interests, whether or not such amounts are distributed to shareholders. To avoid such tax and interest, a Portfolio may elect to “mark to market” its PFIC interests, that is, to treat such interests as sold on the last day of the Portfolio’s fiscal year and to recognize any unrealized gains (or losses, to the extent of previously recognized gains) as ordinary income each year. This election may cause the Portfolio to recognize income prior to the receipt of cash payments with respect to those investments; in order to distribute this income and avoid a tax on the Portfolio, the Portfolio may be required to liquidate portfolio securities that it might otherwise have continued to hold, potentially resulting in additional taxable gain or loss to the Portfolio. Distributions from the Portfolio that are attributable to income or gains earned in respect to PFIC interests are characterized as ordinary income. Each Portfolio (other than the Money Market, Short-Term Investment-Grade, Total Bond Market Index, Global Bond Index, and High Yield Bond Portfolios) may invest in PFICs.

Tax Matters— Investments in REITs and Other Mortgage-Related Instruments. If a Portfolio invests directly or indirectly, including through a REIT or other pass-through entity, in residual interests in real estate mortgage investment conduits (REMICs) or equity interests in taxable mortgage pools (TMPs), a portion of the Portfolio’s income that is attributable to a residual interest in a REMIC or an equity interest in a TMP (such portion referred to in the IRC as an “excess inclusion”) will be subject to U.S. federal income tax in all events including potentially at the Portfolio level under a notice issued by the IRS in October 2006 and U.S. Treasury regulations that have yet to be issued but may apply retroactively. This notice also provides, and the regulations are expected to provide, that excess inclusion income of a registered investment company will be allocated to shareholders of the registered investment company in proportion to the dividends received by such shareholders, with the same consequences as if the shareholders held the related interest directly. As a result, a life insurance company separate account funding a variable contract may be taxed currently to the extent of its share of a Portfolio’s excess inclusion income. In general, where excess inclusion income is allocated to a life insurance company separate account funding a variable life insurance or variable annuity contract, such income cannot be offset by an adjustment to the reserves and thus is currently taxed notwithstanding the more general tax deferral available to insurance company separate accounts funding such contracts .

B-33


 

Time Deposits. Time deposits are subject to the same risks that pertain to domestic issuers of money market instruments, most notably credit risk (and, to a lesser extent, income risk, market risk, and liquidity risk). Additionally, time deposits of foreign branches of U.S. banks and foreign branches of foreign banks may be subject to certain sovereign risks. One such risk is the possibility that a sovereign country might prevent capital, in the form of U.S. dollars, from flowing across its borders. Other risks include adverse political and economic developments, the extent and quality of government regulation of financial markets and institutions, the imposition of foreign withholding taxes, and expropriation or nationalization of foreign issuers. However, time deposits of such issuers will undergo the same type of credit analysis as domestic issuers in which a Vanguard fund invests and will have at least the same financial strength as the domestic issuers approved for the fund.

Trust Preferred Securities . T rust preferred securities are a type of hybrid security in which a parent company issues subordinated debt to an affiliated special purpose trust, which will in turn issue limited-life preferred securities to investors and common securities to the parent company. Investors will receive distributions of the interest the trust receives on the debt issued by the parent company during the term of the preferred securities. The underlying subordinated debt may be secured or unsecured, and it generally ranks slightly higher in terms of payment priority than both common and preferred securities of the issuer, but below its other debt securities. Trust preferred securities generally have a yield advantage over traditional preferred stocks, but unlike preferred stocks, distributions generally are treated as interest rather than dividends for federal income tax purposes and, therefore, are not eligible for the dividends-received deduction available to U.S. corporations for dividends paid by U.S. corporations or the lower federal tax rate applicable to qualified dividends. Trust preferred securities typically have maturities of 30 years or more, may be subject to prepayment by the issuer under certain circumstances, and have periodic fixed or variable interest payments and maturities at face value. In addition, trust preferred securities may allow for deferral of interest payments for up to 5 years or longer. However, during any deferral period, interest will accrue and be taxable for holders of the trust preferred securities. Furthermore, if an issuer of trust preferred securities exercised its right to defer interest payments, the securities would be treated as issued with original issue discount (OID) at that time and all interest on the securities would thereafter be treated as OID as long as the securities remained outstanding. Unlike typical asset-backed securities, trust preferred securities have only one underlying obligor and are not over-collateralized. For that reason, the market may effectively treat trust preferred securities as subordinate corporate debt of the parent company issuer. The risks associated with trust preferred securities typically include those relating to the financial condition of the parent company, as the trust typically has no business operations other than holding the subordinated debt issued by the parent company. Holders of trust preferred securities have limited voting rights to control the activities of the trust and no voting rights with respect to the parent company. There can be no assurance as to the liquidity of trust preferred securities or the ability of holders of the trust preferred securities to sell their holdings.

Warrants. Warrants are instruments that give the holder the right, but not the obligation, to buy an equity security at a specific price for a specific period of time. Changes in the value of a warrant do not necessarily correspond to changes in the value of its underlying security. The price of a warrant may be more volatile than the price of its underlying security, and a warrant may offer greater potential for capital appreciation as well as capital loss. Warrants do not entitle a holder to dividends or voting rights with respect to the underlying security and do not represent any rights in the assets of the issuing company. A warrant ceases to have value if it is not exercised prior to its expiration date. These factors can make warrants more speculative than other types of investments.

When-Issued, Delayed-Delivery, and Forward-Commitment Transactions. When-issued, delayed-delivery, and forward-commitment transactions involve a commitment to purchase or sell specific securities at a predetermined price or yield in which payment and delivery take place after the customary settlement period for that type of security. Typically, no interest accrues to the purchaser until the security is delivered. When purchasing securities pursuant to one of these transactions, payment for the securities is not required until the delivery date. However, the purchaser assumes the rights and risks of ownership, including the risks of price and yield fluctuations and the risk that the security will not be issued as anticipated. When a fund has sold a security pursuant to one of these transactions, the fund does not participate in further gains or losses with respect to the security. If the other party to a delayed-delivery transaction fails to deliver or pay for the securities, the fund could miss a favorable price or yield opportunity or suffer a loss. A fund may renegotiate a when-issued or forward-commitment transaction and may sell the underlying securities before delivery, which may result in capital gains or losses for the fund. When-issued, delayed-delivery, and forward-commitment transactions will not be considered to constitute the issuance, by a fund, of a “senior security,” as that term is defined in Section 18(g) of the 1940 Act, and therefore such transaction will not be subject to the 300% asset coverage requirement otherwise applicable to

B-34


 

borrowings by the fund, if the fund covers the transaction in accordance with the requirements described under the heading “Borrowing.”

Regulatory restrictions in India. Shares of Vanguard Variable Insurance Fund International Portfolio have not been, and will not be, registered under the laws of India and are not intended to benefit from any laws in India promulgated for the protection of shareholders. As a result of regulatory requirements in India, shares of the International Portfolio shall not be knowingly offered to (directly or indirectly) or sold or delivered to (within India); transferred to or purchased by; or held by, for, on the account of, or for the benefit of (i) a “person resident in India” (as defined under applicable Indian law), (ii) an “overseas corporate body” or a “person of Indian origin” (as defined under applicable Indian law), or (iii) any other entity or person disqualified or otherwise prohibited from accessing the Indian securities market under applicable laws, as may be amended from time to time. Investors, prior to purchasing shares of the International Portfolio, must satisfy themselves regarding compliance with these requirements.

SHARE PRICE

Each Portfolio’s share price, called its net asset value , or NAV, is calculated each business day after the close of regular trading on the New York Stock Exchange (the Exchange), generally 4 p.m., Eastern time. NAV per share is computed by dividing the total assets, minus liabilities, of the Portfolio by the number of Portfolio shares outstanding. On U.S. holidays or other days when the Exchange is closed, the NAV is not calculated, and the Portfolios do not sell or redeem shares. However, on those days the value of a Portfolio’s assets may be affected to the extent that the Portfolio holds securities that change in value on those days (such as foreign securities that trade on foreign markets that are open). The underlying Vanguard funds in which the Fund-of-Fund Portfolios invest also do not calculate their NAV on days when the Exchange is closed but the value of their assets may be affected to the extent that they hold securities that change in value on those days (such as foreign securities that trade on foreign markets that are open).

The Exchange typically observes the following holidays: New Year’s Day; Martin Luther King, Jr., Day; Presidents’ Day (Washington’s Birthday); Good Friday; Memorial Day; Independence Day; Labor Day; Thanksgiving Day; and Christmas Day. Although the Fund expects the same holidays to be observed in the future, the Exchange may modify its holiday schedule or hours of operation at any time.

It is the policy of the Money Market Portfolio to attempt to maintain a net asset value of $1 per share for sales and redemptions. The instruments held by the Portfolio are valued on the basis of amortized cost, which does not take into account unrealized capital gains or losses. This involves valuing an instrument at its cost and thereafter assuming a constant amortization to maturity of any discount or premium, regardless of the impact of fluctuating interest rates on the market value of the instrument. While this method provides certainty in valuation, it may result in periods during which value, as determined by amortized cost, is higher or lower than the price which the Portfolio would receive if it sold the instrument. The Portfolio’s holdings will be reviewed by the trustees, at such intervals as they may deem appropriate, to determine whether the Portfolio’s net asset value calculated by using available market quotations deviates from $1 per share based on amortized cost. The extent of any deviation will be examined by the trustees. If such deviation exceeds 1/2 of 1%, the trustees will promptly consider what action, if any, will be initiated. In the event the trustees determine that a deviation exists which may result in material dilution or other unfair results to investors or existing shareholders, they have agreed to take such corrective action as they regard as necessary and appropriate, including selling fund instruments prior to maturity to realize capital gains or losses or to shorten average portfolio maturity; withholding dividends; making a special capital distribution; redeeming shares in kind; or establishing a net asset value per share by using available market quotations.

The use of amortized cost and the maintenance of the Money Market Portfolio’s net asset value at $1 is based on its election to operate under Rule 2a-7 under the 1940 Act. As a condition of operating under that rule, the Portfolio must maintain a dollar-weighted average portfolio maturity of 60 days or less; maintain a dollar-weighted average life of 120 days or less; purchase only instruments having remaining maturities of 397 days or less; meet applicable daily, weekly, and general liquidity requirements; and invest only in securities that are determined by methods approved by the trustees to present minimal credit risks and that are of high quality.

B-35


 

PURCHASE AND REDEMPTION OF SHARES

Purchase of Shares

The purchase price of shares of each Portfolio is the NAV next determined after the purchase request is received in good order, as defined in the Portfolio’s prospectus.

The Total Bond Market Index Portfolio reserves the right to impose a transaction fee of 0.25% on any purchase that, in the opinion of the advisor, would disrupt efficient management of the Portfolio. The advisor may impose this transaction fee if an investor’s aggregate purchases into the Portfolio over a 12-month period exceed, or are expected to exceed, $50 million. The Portfolio may incur substantial transaction costs in absorbing very large investments, and the fee (paid directly to the Portfolio) is intended to protect existing shareholders from being unfairly impacted by such costs. The Portfolio’s advisor will consider several factors in determining whether to apply the fee, including the following:

  • The transaction costs of buying securities, determined in part by the availability of securities at that time.
  • The offsetting effect of any Portfolio redemptions occurring at that time.
  • The Portfolio’s then-current rate of growth.

Exchange of Securities for Shares of a Portfolio. Shares of a Portfolio may be purchased “in kind” (i.e., in exchange for securities, rather than for cash) at the discretion of the Portfolio’s portfolio manager. Such securities must not be restricted as to transfer and must have a value that is readily ascertainable. Securities accepted by the Portfolio will be valued, as set forth in the Portfolio’s prospectus, as of the time of the next determination of NAV after such acceptance. All dividend, subscription, or other rights that are reflected in the market price of accepted securities at the time of valuation become the property of the Portfolio and must be delivered to the Portfolio by the investor upon receipt from the issuer. A gain or loss for federal income tax purposes, depending upon the cost of the securities tendered, would be realized by the investor upon the exchange. Investors interested in purchasing portfolio shares in kind should contact Vanguard.

Redemption of Shares

The redemption price of shares of each Portfolio is the NAV next determined after the redemption request is received in good order, as defined in the Portfolio’s prospectus.

Each Portfolio can postpone payment of redemption proceeds for up to seven calendar days. In addition, each Portfolio can suspend redemptions and/or postpone payments of redemption proceeds beyond seven calendar days (1) during any period that the Exchange is closed or trading on the Exchange is restricted as determined by the SEC; (2) during any period when an emergency exists, as defined by the SEC, as a result of which it is not reasonably practicable for the Portfolio to dispose of securities it owns or to fairly determine the value of its assets; or (3) for such other periods as the SEC may permit, including in connection with a determination by the board of a money market fund under Rule 22e-3 under the 1940 Act to suspend redemptions and postpone payment of redemption proceeds in order to facilitate an orderly liquidation of a money market fund. In addition, in accordance with Rule 2a-7 under the 1940 Act, the board of trustees of a retail or institutional money market fund may implement liquidity fees and redemption gates if a retail or institutional money market fund’s weekly liquid assets fall below established thresholds.

The Trust has filed a notice of election with the SEC to pay in cash all redemptions requested by any shareholder of record limited in amount during any 90-day period to the lesser of $250,000 or 1% of the net assets of a Portfolio at the beginning of such period.

If Vanguard determines that it would be detrimental to the best interests of the remaining shareholders of a Portfolio to make payment wholly or partly in cash, the Portfolio may pay the redemption price in whole or in part by a distribution in kind of readily marketable securities held by the Portfolio in lieu of cash in conformity with applicable rules of the SEC. Investors may incur brokerage charges on the sale of such securities received in payment of redemptions.

The Portfolios do not charge redemption fees. Shares redeemed may be worth more or less than what was paid for them, depending on the market value of the securities held by the Portfolio.

B-36


 

Right to Change Policies

Vanguard reserves the right, without notice, to (1) alter, add, or discontinue any conditions of purchase (including eligibility requirements), redemption, exchange, 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 shareholder or 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 in the best interest of a fund.

MANAGEMENT OF THE FUND

Vanguard

The Fund is part of the Vanguard group of investment companies, which consists of over 200 funds. Each fund is a series of a Delaware statutory trust, and through the trusts’ jointly owned subsidiary, Vanguard, the funds obtain at cost virtually all of their corporate management, administrative, and distribution services. Vanguard also provides investment advisory services on an at-cost basis to several of the Vanguard funds.

Vanguard was established and operates under an Amended and Restated Funds’ Service Agreement (the Agreement). Vanguard employs a supporting staff of management and administrative personnel needed to provide the requisite services to the funds and also furnishes the funds with necessary office space, furnishings, and equipment. The funds’ officers are also employees of Vanguard.

Vanguard, Vanguard Marketing Corporation (VMC), the funds, and the funds’ advisors have adopted codes of ethics designed to prevent employees who may have access to nonpublic information about the trading activities of the funds (access persons) from profiting from that information. The codes of ethics permit access persons to invest in securities for their own accounts, including securities that may be held by a fund, but place substantive and procedural restrictions on the trading activities of access persons. For example, the codes of ethics require that access persons receive advance approval for most securities trades to ensure that there is no conflict with the trading activities of the funds.

For all Portfolios except the Fund-of-Fund Portfolios. Vanguard provides corporate management, administrative, and distribution services at cost. Each Portfolio pays its share of Vanguard’s total expenses, which are allocated among the Portfolios under methods approved by the board of trustees of each Portfolio. In addition, each Portfolio bears its own direct expenses, such as legal, auditing, and custodial fees. The Agreement provides that each Portfolio may be called upon to invest up to 0.40% of its net assets in Vanguard. The amounts that each Portfolio has invested are adjusted from time to time in order to maintain the proportionate relationship between each Portfolio’s relative net assets and its contribution to Vanguard’s capital.

B-37


 

As of December 31, 2017, each Portfolio had contributed capital to Vanguard as follows:  
 
    Percentage of  
  Capital Portfolio’s Percent of
  Contribution to Average Vanguard’s
Vanguard Variable Insurance Fund Portfolio Vanguard Net Assets Capitalization
Balanced Portfolio $ xx 0.xx% 0.xx%

Real Estate Index Portfolio xx xx xx
Short-Term Investment-Grade Portfolio xx xx xx
Small Company Growth Portfolio xx xx xx
Total Bond Market Index Portfolio xx xx xx

 

For the Fund-of-Fund Portfolios. The Agreement provides that each Portfolio will not contribute to Vanguard’s capitalization or pay for corporate management, administrative, and distribution services provided by Vanguard. However, each Portfolio will bear its own direct expenses, such as legal, auditing, and custodial fees. In addition, the Agreement further provides that each Portfolio’s direct expenses will be offset, in whole or in part, by a reimbursement from Vanguard for (1) the Portfolio’s contributions to the cost of operating the underlying Vanguard funds in which the Portfolio invests, and (2) certain savings in administrative and marketing costs that Vanguard expects to derive from the Portfolio’s operations. Each Portfolio expects that the reimbursements should be sufficient to offset most or all of the direct expenses incurred by the Portfolio. Therefore, each Portfolio is expected to operate at a very low—or zero—direct expense ratio. Of course, there is no guarantee that this will always be the case.

Although each Portfolio is not expected to incur any net expenses directly, the Portfolio’s shareholders indirectly bear the expenses of the underlying Vanguard funds. As of December 31, 2017 , the Acquired Fund Fees and Expenses of the Total Stock Market Index Portfolio were 0.xx%. For the Conservative Allocation and Moderate Allocation Portfolios, the Acquired Fund Fees and Expenses were 0.xx% each.

Management . Corporate management and administrative services include (1) executive staff, (2) accounting and financial, (3) legal and regulatory, (4) shareholder account maintenance, (5) monitoring and control of custodian relationships, (6) shareholder reporting, and (7) review and evaluation of advisory and other services provided to the funds by third parties.

Distribution . Vanguard Marketing Corporation, 100 Vanguard Boulevard, Malvern, PA 19355, a wholly owned subsidiary of Vanguard, is the principal underwriter for the funds and in that capacity performs and finances marketing, promotional, and distribution activities (collectively, marketing and distribution activities) that are primarily intended to result in the sale of the funds’ shares. VMC offers shares of each fund for sale on a continuous basis and will use all reasonable efforts in connection with the distribution of shares of the funds. VMC performs marketing and distribution activities at cost in accordance with the conditions of a 1981 SEC exemptive order that permits the Vanguard funds to internalize and jointly finance the marketing, promotion, and distribution of their shares. The funds’ trustees review and approve the marketing and distribution expenses incurred by the funds, including the nature and cost of the activities and the desirability of each fund’s continued participation in the joint arrangement.

To ensure that each fund’s participation in the joint arrangement falls within a reasonable range of fairness, each fund contributes to VMC’s marketing and distribution expenses in accordance with an SEC-approved formula. Under that formula, one half of the marketing and distribution expenses are allocated among the funds based upon their relative net

B-38


 

assets. The remaining half of those expenses are allocated among the funds based upon each fund’s sales for the preceding 24 months relative to the total sales of the funds as a group, provided, however, that no fund’s aggregate quarterly rate of contribution for marketing and distribution expenses shall exceed 125% of the average marketing and distribution expense rate for Vanguard and that no fund shall incur annual marketing and distribution expenses in excess of 0.20% of its average month-end net assets. Each fund’s contribution to these marketing and distribution expenses helps to maintain and enhance the attractiveness and viability of the Vanguard complex as a whole, which benefits all of the funds and their shareholders.

VMC’s principal marketing and distribution expenses are for advertising, promotional materials, and marketing personnel. Other marketing and distribution activities of an administrative nature that VMC undertakes on behalf of the funds may include, but are not limited to:

  • Conducting or publishing Vanguard-generated research and analysis concerning the funds, other investments, the financial markets, or the economy.
  • Providing views, opinions, advice, or commentary concerning the funds, other investments, the financial markets, or the economy.
  • Providing analytical, statistical, performance, or other information concerning the funds, other investments, the financial markets, or the economy.
  • Providing administrative services in connection with investments in the funds or other investments, including, but not limited to, shareholder services, recordkeeping services, and educational services.
  • Providing products or services that assist investors or financial service providers (as defined below) in the investment decision-making process.
  • Providing promotional discounts, commission-free trading, fee waivers, and other benefits to clients of Vanguard Brokerage Services ® who maintain qualifying investments in the funds.
  • Sponsoring, jointly sponsoring, financially supporting, or participating in conferences, programs, seminars, presentations, meetings, or other events involving fund shareholders, financial service providers, or others concerning the funds, other investments, the financial markets, or the economy, such as industry conferences, prospecting trips, due diligence visits, training or education meetings, and sales presentations.

VMC performs most marketing and distribution activities itself. Some activities may be conducted by third parties pursuant to shared marketing arrangements under which VMC agrees to share the costs and performance of marketing and distribution activities in concert with a financial service provider. Financial service providers include, but are not limited to, investment advisors, broker-dealers, financial planners, financial consultants, banks, and insurance companies. Under these cost- and performance-sharing arrangements, VMC may pay or reimburse a financial service provider (or a third party it retains) for marketing and distribution activities that VMC would otherwise perform. VMC’s cost- and performance-sharing arrangements may be established in connection with Vanguard investment products or services offered or provided to or through the financial service providers. VMC’s arrangements for shared marketing and distribution activities may vary among financial service providers, and its payments or reimbursements to financial service providers in connection with shared marketing and distribution activities may be significant. VMC participates in an offshore arrangement established with a third party to provide marketing, promotional, and other services to qualifying Vanguard funds that are distributed in certain foreign countries on a private-placement basis to government-sponsored and other institutional investors. In exchange for such services, the third party receives an annual base (fixed) fee and may also receive discretionary fees or performance adjustments.

In connection with its marketing and distribution activities, VMC may give financial service providers (or their representatives) (1) promotional items of nominal value that display Vanguard’s logo, such as golf balls, shirts, towels, pens, and mouse pads; (2) gifts that do not exceed $100 per person annually and are not preconditioned on achievement of a sales target; (3) an occasional meal, a ticket to a sporting event or the theater, or comparable entertainment that is neither so frequent nor so extensive as to raise any question of propriety and is not preconditioned on achievement of a sales target; and (4) reasonable travel and lodging accommodations to facilitate participation in marketing and distribution activities.

VMC, as a matter of policy, does not pay asset-based fees, sales-based fees, or account-based fees to financial service providers in connection with its marketing and distribution activities for the Vanguard funds. VMC policy also prohibits marketing and distribution activities that are intended, designed, or likely to compromise suitability determinations by, or the fulfillment of any fiduciary duties or other obligations that apply to, financial service providers. Nonetheless, VMC’s

B-39


 

marketing and distribution activities are primarily intended to result in the sale of the funds’ shares, and as such, its activities, including shared marketing and distribution activities, may influence participating financial service providers (or their representatives) to recommend, promote, include, or invest in a Vanguard fund or share class. In addition, Vanguard or any of its subsidiaries may retain a financial service provider to provide consulting or other services, and that financial service provider also may provide services to investors. Investors should consider the possibility that any of these activities or relationships may influence a financial service provider’s (or its representatives’) decision to recommend, promote, include, or invest in a Vanguard fund or share class. Each financial service provider should consider its suitability determinations, fiduciary duties, and other legal obligations (or those of its representatives) in connection with any decision to consider, recommend, promote, include, or invest in a Vanguard fund or share class.

The following table describes the expenses of Vanguard and VMC that are incurred by the Portfolios (except the Fund-of-Funds Portfolios) on an at-cost basis. Amounts captioned “Management and Administrative Expenses” include the Portfolio‘s allocated share of expenses associated with the management, administrative, and transfer agency services Vanguard provides to the Vanguard funds. Amounts captioned “Marketing and Distribution Expenses” include the Portfolio‘s allocated share of expenses associated with the marketing and distribution activities that VMC conducts on behalf of the Vanguard funds.

As is the case with all mutual funds, transaction costs incurred by the the Portfolios for buying and selling securities are not reflected in the table. Annual Shared Fund Operating Expenses are based on expenses incurred in the fiscal years ended December 31, 2015 , 2016 , and 2017 , and are presented as a percentage of each Portfolio‘s average month-end net assets.

Officers and Trustees

Each Vanguard fund is governed by the board of trustees of its trust and a single set of officers. Consistent with the board’s corporate governance principles, the trustees believe that their primary responsibility is oversight of the management of each fund for the benefit of its shareholders, not day-to-day management. The trustees set broad policies for the funds; select investment advisors; monitor fund operations, regulatory compliance, performance, and costs; nominate and select new trustees; and elect fund officers. Vanguard manages the day-to-day operations of the funds under the direction of the board of trustees.

The trustees play an active role, as a full board and at the committee level, in overseeing risk management for the funds. The trustees delegate the day-to-day risk management of the funds to various groups, including portfolio review, investment management, risk management, compliance, legal, fund accounting, and fund financial services. These groups provide the trustees with regular reports regarding investment, valuation, liquidity, and compliance, as well as the risks associated with each. The trustees also oversee risk management for the funds through regular interactions with the funds’ internal and external auditors.

The full board participates in the funds’ risk oversight, in part, through the Vanguard funds’ compliance program, which covers the following broad areas of compliance: investment and other operations; recordkeeping; valuation and pricing; communications and disclosure; reporting and accounting; oversight of service providers; fund governance; and codes of ethics, insider trading controls, and protection of nonpublic information. The program seeks to identify and assess risk through various methods, including through regular interdisciplinary communications between compliance professionals and business personnel who participate on a daily basis in risk management on behalf of the funds. The funds’ chief compliance officer regularly provides reports to the board in writing and in person.

The audit committee of the board, which is composed of JoAnn Heffernan Heisen, F. Joseph Loughrey, Mark Loughridge, Sarah Bloom Raskin , and Peter F. Volanakis, each of whom is an independent trustee, oversees management of financial risks and controls. The audit committee serves as the channel of communication between the independent auditors of the funds and the board with respect to financial statements and financial reporting processes, systems of internal control, and the audit process. Vanguard’s head of internal audit reports directly to the audit committee and provides reports to the committee in writing and in person on a regular basis. Although the audit committee is responsible for overseeing the management of financial risks, the entire board is regularly informed of these risks through committee reports.

All of the trustees bring to each fund’s board a wealth of executive leadership experience derived from their service as executives (in many cases chief executive officers), board members, and leaders of diverse public operating companies, academic institutions, and other organizations. In determining whether an individual is qualified to serve as a trustee of the funds, the board considers a wide variety of information about the trustee, and multiple factors contribute to the board’s decision. Each trustee is determined to have the experience, skills, and attributes necessary to serve the funds and their shareholders because each trustee demonstrates an exceptional ability to consider complex business and

B-41


 

financial matters, evaluate the relative importance and priority of issues, make decisions, and contribute effectively to the deliberations of the board. The board also considers the individual experience of each trustee and determines that the trustee’s professional experience, education, and background contribute to the diversity of perspectives on the board. The business acumen, experience, and objective thinking of the trustees are considered invaluable assets for Vanguard management and, ultimately, the Vanguard funds’ shareholders. The specific roles and experience of each board member that factor into this determination are presented on the following pages. The mailing address of the trustees and officers is P.O. Box 876, Valley Forge, PA 19482.

All but one of the trustees are independent. The independent trustees designate a lead independent trustee. The lead independent trustee is a spokesperson and principal point of contact for the independent trustees and is responsible for coordinating the activities of the independent trustees, including calling regular executive sessions of the independent trustees; developing the agenda of each meeting together with the chairman; and chairing the meetings of the independent trustees. The lead independent trustee also chairs the meetings of the audit, compensation, and nominating committees. The board also has two investment committees, which consist of independent trustees and the sole interested trustee.

The independent trustees appoint the chairman of the board. The roles of chairman of the board and chief executive officer currently are held by the same person; as a result, the chairman of the board is an “interested” trustee. The independent trustees generally believe that the Vanguard funds’ chief executive officer is best qualified to serve as chairman and that fund shareholders benefit from this leadership structure through accountability and strong day-to-day leadership.

Board Committees: The Trust‘s board has the following committees:

  • Audit Committee: This committee oversees the accounting and financial reporting policies, the systems of internal controls, and the independent audits of each fund. The following independent trustees serve as members of the committee: Ms. Heisen, Mr. Loughrey, Mr. Loughridge, Ms. Raskin, and Mr. Volanakis. The committee held xxx meetings during the Portfolios‘ fiscal year ended December 31, 2017 .
  • Compensation Committee: This committee oversees the compensation programs established by each fund for the benefit of its trustees. All independent trustees serve as members of the committee. The committee held xxx meetings during the Portfolios‘ fiscal year ended December 31, 2017 .
  • Investment Committees: These committees assist the board in its oversight of investment advisors to the funds and in the review and evaluation of materials relating to the board’s consideration of investment advisory agreements with the funds. Each trustee serves on one of two investment committees. Each investment committee held xxx meetings during the Portfolios‘ fiscal year ended December 31, 2017 .
  • Nominating Committee: This committee nominates candidates for election to the board of trustees of each fund. The committee also has the authority to recommend the removal of any trustee. All independent trustees serve as members of the committee. The committee held xxx meetings during the Portfolios‘ fiscal year ended December 31, 2017 .

B-46


 

The Nominating Committee will consider shareholder recommendations for trustee nominees. Shareholders may send recommendations to Mr. Loughridge, chairman of the committee.

Trustee Compensation

The same individuals serve as trustees of all Vanguard funds and each fund pays a proportionate share of the trustees’ compensation. The funds employ their officers on a shared basis; however, officers are compensated by Vanguard, not the funds. The trustees and officers of the Conservative Allocation, Moderate Allocation, and Total Stock Market Index Portfolios will receive no remuneration directly from the Portfolios. However, the Portfolios’ underlying funds pay their proportionate share of the trustees’ compensation and the officers’ salaries and benefits.

Independent Trustees. The funds compensate their independent trustees (i.e., the ones who are not also officers of the funds) in three ways:

  • The independent trustees receive an annual fee for their service to the funds, which is subject to reduction based on absences from scheduled board meetings.
  • The independent trustees are reimbursed for the travel and other expenses that they incur in attending board meetings.
  • Upon retirement (after attaining age 65 and completing five years of service), the independent trustees who began their service prior to January 1, 2001, receive a retirement benefit under a separate account arrangement. As of January 1, 2001, the opening balance of each eligible trustee’s separate account was generally equal to the net present value of the benefits he or she had accrued under the trustees’ former retirement plan. Each eligible trustee’s separate account will be credited annually with interest at a rate of 7.5% until the trustee receives his or her final distribution. Those independent trustees who began their service on or after January 1, 2001, are not eligible to participate in the plan.

“Interested” Trustees . Mr. McNabb and Mr. Buckley serve as trustees but are not paid in this capacity. They are, however, paid in their role as officers of Vanguard.

Compensation Table. The following table provides compensation details for each of the trustees. We list the amounts paid as compensation and accrued as retirement benefits by the Fund for each trustee. In addition, the table shows the total amount of benefits that we expect each trustee to receive from all Vanguard funds upon retirement and the total amount of compensation paid to each trustee by all Vanguard funds.

Ownership of Fund Shares

All trustees allocate their investments among the various Vanguard funds based on their own investment needs. The Portfolios are mutual funds used solely as investment options for annuity or life insurance contracts offered by insurance companies, which can only be purchased through a contract offered by an insurance company. Accordingly, the trustees cannot directly own shares of the Portfolios. The following table shows each trustee’s ownership of shares of all Vanguard funds served by the trustee as of December 31, 2017 .

Portfolio Holdings Disclosure Policies and Procedures

Introduction

Vanguard and the boards of trustees of the Vanguard funds (Boards) have adopted Portfolio Holdings Disclosure Policies and Procedures (Policies and Procedures) to govern the disclosure of the portfolio holdings of each Vanguard fund. Vanguard and the Boards considered each of the circumstances under which Vanguard fund portfolio holdings may be disclosed to different categories of persons under the Policies and Procedures. Vanguard and the Boards also considered actual and potential material conflicts that could arise in such circumstances between the interests of Vanguard fund shareholders, on the one hand, and those of the fund’s investment advisor, distributor, or any affiliated person of the fund, its investment advisor, or its distributor, on the other. After giving due consideration to such matters and after the exercise of their fiduciary duties and reasonable business judgment, Vanguard and the Boards determined that the Vanguard funds have a legitimate business purpose for disclosing portfolio holdings to the persons described in each of the circumstances set forth in the Policies and Procedures and that the Policies and Procedures are reasonably designed to ensure that disclosure of portfolio holdings and information about portfolio holdings is in the best interests of fund shareholders and appropriately addresses the potential for material conflicts of interest.

The Boards exercise continuing oversight of the disclosure of Vanguard fund portfolio holdings by (1) overseeing the implementation and enforcement of the Policies and Procedures, the Code of Ethics, and the Policies and Procedures Designed to Prevent the Misuse of Inside Information (collectively, the portfolio holdings governing policies) by the chief compliance officer of Vanguard and the Vanguard funds; (2) considering reports and recommendations by the chief compliance officer concerning any material compliance matters (as defined in Rule 38a-1 under the 1940 Act and Rule 206(4)-7 under the Investment Advisers Act of 1940) that may arise in connection with any portfolio holdings governing policies; and (3) considering whether to approve or ratify any amendment to any portfolio holdings governing policies. Vanguard and the Boards reserve the right to amend the Policies and Procedures at any time and from time to time without prior notice at their sole discretion. For purposes of the Policies and Procedures, the term “portfolio holdings” means the equity and debt securities (e.g., stocks and bonds) held by a Vanguard fund and does not mean the cash investments, derivatives, and other investment positions (collectively, other investment positions) held by the fund.

The Vanguard funds have not given their consent to any such use or disclosure and no person or

B-50


 

agent of Vanguard is authorized to give such consent except as approved in writing by the Boards of the Vanguard funds. Disclosure of portfolio holdings or other investment positions by Vanguard to broker-dealers must be authorized by a Vanguard fund officer or a Principal of Vanguard.

Disclosure of Nonmaterial Information

The Policies and Procedures permit Vanguard fund officers, Vanguard fund portfolio managers, and other Vanguard representatives (collectively, Approved Vanguard Representatives) to disclose any views, opinions, judgments, advice, or commentary, or any analytical, statistical, performance, or other information, in connection with or relating to a Vanguard fund or its portfolio holdings and/or other investment positions (collectively, commentary and analysis) or any changes in the portfolio holdings of a Vanguard fund that occurred after the end of the most recent calendar quarter (recent portfolio changes) to any person if (1) such disclosure serves a legitimate business purpose, (2) such disclosure does not effectively result in the disclosure of the complete portfolio holdings of any Vanguard fund (which can be disclosed only in accordance with the Policies and Procedures), and (3) such information does not constitute material nonpublic information. Disclosure of commentary and analysis or recent portfolio changes by Vanguard, Vanguard Marketing Corporation, or a Vanguard fund must be authorized by a Vanguard fund officer or a Principal of Vanguard.

An Approved Vanguard Representative must make a good faith determination whether the information constitutes material nonpublic information, which involves an assessment of the particular facts and circumstances. Vanguard believes that in most cases recent portfolio changes that involve a few or even several securities in a diversified portfolio or commentary and analysis would be immaterial and would not convey any advantage to a recipient in making an investment decision concerning a Vanguard fund. Nonexclusive examples of commentary and analysis about a Vanguard fund include (1) the allocation of the fund’s portfolio holdings and other investment positions among various asset classes, sectors, industries, and countries; (2) the characteristics of the stock and bond components of the fund’s portfolio holdings and other investment positions; (3) the attribution of fund returns by asset class, sector, industry, and country; and (4) the volatility characteristics of the fund. Approved Vanguard Representatives may, at their sole discretion, deny any request for information made by any person, and may do so for any reason or for no reason.

Disclosure of this information to an issuer is conditioned on the issuer being subject to a written agreement imposing a duty of confidentiality, including a duty not to trade on the basis of any material nonpublic information. The frequency with which

B-51


 

portfolio holdings information concerning a security may be disclosed to the issuer of such security, and the length of the lag, if any, between the date of the information and the date on which the information is disclosed to the issuer, is determined based on the facts and circumstances, including, without limitation, the nature of the portfolio holdings information to be disclosed, the risk of harm to the funds and their shareholders, and the legitimate business purposes served by such disclosure. The frequency of disclosure to an issuer cannot be determined in advance of a specific request and will vary based upon the particular facts and circumstances and the legitimate business purposes, but in unusual situations could be as frequent as daily, with no lag.

In addition, no person is authorized to make disclosure pursuant to the Policies and Procedures if such disclosure is otherwise unlawful under the antifraud provisions of the federal securities laws (as defined in Rule 38a-1 under the 1940 Act).

Prohibitions on Receipt of Compensation or Other Consideration

Independent Third-Party Advisors

For funds that are advised by independent third-party advisory firms unaffiliated with Vanguard, the board of trustees of each fund hires investment advisory firms, not individual portfolio managers, to provide investment advisory services to such funds. Vanguard negotiates each advisory agreement, which contains advisory fee arrangements, on an arm’s length basis with the advisory firm. Each advisory agreement is reviewed annually by each fund’s board of trustees, taking into account numerous factors, which include, without limitation, the nature, extent, and quality of the services provided; investment performance; and the fair market value of the services provided. Each advisory agreement is between the Trust and the advisory firm, not between the Trust and the portfolio manager. The structure of the advisory fee paid to each unaffiliated investment advisory firm is described in the following sections. In addition, each firm has established policies and procedures designed to address the potential for conflicts of interest. Each firm’s compensation structure and management of potential conflicts of interest are summarized by the advisory firm in the following sections for the fiscal year ended December 31, 2017 .

A fund is party to an investment advisory agreement with each of its independent third-party advisors whereby the advisor manages the investment and reinvestment of the portion of the fund’s assets that the fund’s board of trustees determines to assign to the advisor. In this capacity, each advisor continuously reviews, supervises, and administers the investment program for its portion of the fund’s assets. Hereafter, each portion is referred to as the advisor’s Portfolio. Each advisor discharges its responsibilities subject to the supervision and oversight of Vanguard’s Portfolio Review Department and the officers and trustees of the fund. Vanguard’s Portfolio Review Department is responsible for recommending changes in a fund’s advisory arrangements to the fund’s board of trustees, including changes in the amount of assets allocated to each advisor, and recommendations to hire, terminate, or replace an advisor.

I. Capital Growth Portfolio

PRIMECAP Management Company (PRIMECAP), an investment advisory services firm founded in 1983, is a California corporation whose outstanding shares are owned by its directors and officers. The directors of the corporation and the offices they currently hold are Mitchell J. Milias, Chairman Emeritus; Theo A. Kolokotrones, Chairman; Joel P. Fried, President; Alfred W. Mordecai, Vice Chairman; and M. Mohsin Ansari, Executive Vice President. PRIMECAP provides investment advisory services to endowment funds, employee benefit plans, and foundations unrelated to Vanguard.

The Portfolio pays PRIMECAP on a quarterly basis. The advisory fee is a percentage of average daily net assets under management during the most recent fiscal quarter.

During the fiscal years ended December 31, 2015 , 2016 , and 2017 , the Capital Growth Portfolio incurred investment advisory fees of approximately $1,313,000, $1,328,000, and $ xx , respectively.

1. Other Accounts Managed

Theo A. Kolokotrones, Joel P. Fried, Alfred W. Mordecai, M. Mohsin Ansari, and James Marchetti jointly manage the Capital Growth Portfolio; as of December 31, 2017 , the Portfolio held assets of $xx million. As of December 31, 2017 , the named portfolio managers also jointly managed xx other registered investment companies with total assets of $xx billion (none of which had advisory fees based on account performance).

billion; Mr. Mordecai, xx other accounts with total assets of $xx billion; Mr. Ansari, xx other accounts with total assets of $xx billion; and Mr. Marchetti, xx other accounts with total assets of $xx billion (none of which had advisory fees based on account performance).

2. Material Conflicts of Interest

PRIMECAP employs a multimanager approach to managing its clients’ portfolios. In addition to mutual funds, a portfolio manager may also manage separate accounts for institutional clients. Conflicts of interest may arise with aggregation or allocation of securities trades amongst the Portfolio and other accounts. The investment objective of the Portfolio and strategies used to manage the Portfolio may differ from other accounts, and the performance may be impacted as well. Portfolio managers who have day-to-day management responsibilities with respect to more than one fund or other account may be presented with several potential or actual conflicts of interest. For example, the management of multiple funds and/or other accounts may result in a portfolio manager devoting unequal time and attention to the management of each fund and/or other account. If a portfolio manager identifies a limited investment opportunity that may be suitable for more than one fund or other account, a fund may not be able to take full advantage of the opportunity because of an allocation of filled purchase or sale orders across all eligible funds and other accounts managed by the portfolio managers. PRIMECAP has adopted best execution and trade allocation policies and procedures to prevent potential conflicts of interest that may arise between mutual funds and separate accounts, whereby a client or clients may be disadvantaged by trades executed in other clients’ portfolios on the same security. These policies and procedures are strictly monitored and are reviewed by PRIMECAP. Investment personnel of the firm or its affiliates may be permitted to be commercially or professionally involved with an issuer of securities. Any potential conflicts of interest from such involvement would be monitored for compliance with the firm’s Code of Ethics.

3. Description of Compensation

Compensation is paid solely by PRIMECAP. Each portfolio manager receives a fixed salary that is in part based on industry experience as well as contribution to the firm. On an annual basis, each portfolio manager’s compensation may be adjusted according to market conditions and/or to reflect his past performance.

In addition, each portfolio manager may receive a bonus partially based on the Portfolio’s pre-tax return and the total value of assets managed by that portfolio manager. Performance is measured on a relative basis, using the S&P 500 Index as the benchmark, and the bonuses are earned only when performance exceeds that of the S&P 500. The value of assets managed by PRIMECAP is not a factor in determination of a portfolio manager’s bonus. Bonuses earned are accrued and paid ratably according to the following schedule over rolling three-year periods: 50% in year one, 33% in year two, and 17% in year three. Although the bonus is determined by pre-tax returns, each portfolio manager considers tax consequences in taxable accounts as part of his decision-making process.

The portfolio managers do not receive deferred compensation but participate in a profit-sharing plan available to all employees of PRIMECAP; amounts are determined as a percentage of the employee’s eligible compensation for a calendar year based on IRS limitations.

Each portfolio manager is a principal of PRIMECAP and receives quarterly dividends based on his or her equity in the company.

II. Diversified Value Portfolio

Barrow, Hanley, Mewhinney & Strauss, LLC (Barrow, Hanley), a Delaware limited liability company, is an investment management firm founded in 1979 that provides investment advisory services to separately managed U.S. and non-U.S. equity, fixed income, and balanced portfolios for large institutional clients, mutual funds, employee benefit plans, endowments, foundations, insurance companies, limited liability companies, and other institutions and individuals. Barrow, Hanley is a subsidiary of OM Asset Management plc (OMAM), a publicly held company traded on the New York Stock Exchange.

The Portfolio pays the advisor a base fee plus or minus a performance adjustment. The base fee, which is paid quarterly, is a percentage of average daily net assets under management during the most recent fiscal quarter. The performance adjustment, also paid quarterly, is based on the cumulative total return of the Portfolio relative to that of the MSCI Prime Market 750 Index over the preceding 36-month period.

B-54


 

During the fiscal years ended December 31, 2015 , 2016 , and 2017 , the Diversified Value Portfolio incurred investment advisory fees of approximately $1,419,000 (before a performance-based decrease of $335,000), $1,329,000 (before a performance-based decrease of $333,000), and $xx (before a performance-based decrease of $xx,000), respectively,.

1. Other Accounts Managed

Jeff G. Fahrenbruch is a portfolio manager of the Diversified Value Portfolio; as of December 31, 2017 , the Portfolio held assets of $xx billion. As of December 31, 2017 , Mr. Fahrenbruch also co-managed xx other registered investment company with total assets of approximately $xx billion (with advisory fees based on account performance); xx other pooled investment vehicle with total assets of $xx million (advisory fees not based on account performance), and xx other accounts with total assets of $xx billion (none of which had advisory fees based on account performance).

David W. Ganucheau is a portfolio manager of the Diversified Value Portfolio; as of December 31, 2017 , the Portfolio held assets of $xx billion.

2. Material Conflicts of Interest

Actual or potential conflicts of interest may arise when a portfolio manager has management responsibilities to more than one account (including the Portfolio). Barrow, Hanley manages potential conflicts between funds or with other types of accounts through allocation policies and procedures, internal review processes, and oversight by directors and independent third parties to ensure that no client, regardless of type or fee structure, is intentionally favored or disfavored at the expense of another. Barrow, Hanley investment management and trading policies are designed to address potential conflicts in situations where two or more funds or accounts participate in investment decisions involving the same securities.

3. Description of Compensation

Compensation, or remuneration, is paid or awarded to BHMS employees for the services they provide to the Firm. In addition to base salary, all BHMS Portfolio Managers and Analysts share in a bonus pool that is distributed semi-annually. Portfolio Managers and Analysts are rated on their value added to the team-oriented investment process. Total compensation is awarded with respect to all accounts managed, and does not distinguish between specific accounts managed by a Portfolio Manager and does not encourage excessive risk-taking. Bonuses are paid at the discretion of the Firm.

The compensation of Portfolio Managers is not directly tied to fund performance or growth in assets for any fund or other account managed by a Portfolio Manager and Portfolio Managers are not compensated for bringing in new business. Growth in assets from the appreciation of existing assets and/or growth in new assets will increase revenues and profit. The consistent, long-term growth in assets at any investment firm is, to a great extent, dependent upon the success of the portfolio management team. The compensation of the portfolio management team at BHMS will increase over time, if and when assets continue to grow through competitive performance.

In addition, many of BHMS’ key investment personnel have a long-term incentive compensation plan in the form of an equity interest in Barrow, Hanley, Mewhinney & Strauss, LLC.

III. Growth Portfolio

The Portfolio pays each of its independent third-party investment advisors a base fee plus or minus a performance adjustment. Each base fee, which is paid quarterly, is a percentage of average daily net assets managed by the advisor during the most recent fiscal quarter. The performance adjustment, also paid quarterly, is based on the cumulative total return of each advisor’s portion of the Portfolio relative to that of the Russell 1000 Growth Index over the preceding 36-month period (60-month period for William Blair & Company).

During the fiscal years ended December 31, 2015 , 2016 , and 2017 , the Growth Portfolio incurred aggregate investment advisory fees of approximately $665,000 (before a performance-based increase of $134,000), $637,000 (before a performance-based increase of $21,000), and $xx (before a performance-based increase of $xx), respectively.

A. Jackson Square Partners, LLC (Jackson Square)

Jackson Square Partners, LLC, is an investment management firm founded in 2014. Jackson Square is organized as a Delaware limited liability company with principal offices at 101 California Street, Suite 3750, San Francisco, CA 94111.

1. Other Accounts Managed

Christopher J. Bonavico co-manages a portion of the Growth Portfolio; as of December 31, 2017 , the Portfolio held assets of $xx million. As of December 31, 2017 , Mr. Bonavico also managed xx other registered investment companies with total assets of $xx billion (advisory fees based on account performance for xx of these accounts with total assets of $xx billion), xx other pooled investment vehicles with total assets of $xx billion (advisory fees not based on account performance), and xx other accounts with total assets of $xx billion (advisory fees based on account performance for xx of these accounts with total assets of $xx million).

Christopher M. Ericksen co-manages a portion of the Growth Portfolio; as of December 31, 2017 , the Portfolio held assets of $xx million. As of December 31, 2017 , Mr. Ericksen also managed xx other registered investment companies with total assets of $xx billion (advisory fees based on account performance for xx of these accounts with total assets of $xx billion), xx other pooled investment vehicles with total assets of $xx million (advisory fees not based on account performance), and xx other accounts with total assets of $xx billion (advisory fees based on account performance for xx of these accounts with total assets of $xx million).

Daniel J. Prislin co-manages a portion of the Growth Portfolio; as of December 31, 2017 , the Portfolio held assets of $xx million. As of December 31, 2017 , Mr. Prislin also co-managed xx other registered investment companies with total assets of $xx billion (advisory fees based on account performance for xx of these accounts with total assets of $xx billion), xx other pooled investment vehicles with total assets of $xx million (advisory fees not based on account performance), and xx other accounts with total assets of $xx billion (advisory fees based on account performance for xx of these accounts with total assets of $xx million).

Jeffrey S. Van Harte co-manages a portion of the Growth Portfolio; as of December 31, 2017 , the Portfolio held assets of $xx million. As of December 31, 2017 , Mr. Van Harte also co-managed xx other registered investment companies with total assets of $xx billion (advisory fees based on account performance for xx of these accounts with total assets of $xx billion), xx other pooled investment vehicles with total assets of $xx million (advisory fees not based on account performance), and xx other accounts with total assets of $xx billion (advisory fees based on account performance for xx of these accounts with total assets of $xxmillion).

2. Material Conflicts of Interest

Individual portfolio managers perform investment management services for other funds or accounts similar to those provided to the Jackson Square Portfolio, and the investment action for each other fund or account and the Jackson Square Portfolio may differ. For example, one fund or account may be selling a security, while another fund or account may be purchasing or holding the same security. As a result, transactions executed for one fund or account or the Jackson Square Portfolio may adversely affect the value of securities held by another fund or account or the Jackson Square Portfolio. In addition, the management of multiple other funds or accounts and the Jackson Square Portfolio may give rise to potential conflicts of interest, as a portfolio manager must allocate time and effort to multiple funds or accounts and the Jackson Square Portfolio. A portfolio manager may discover an investment opportunity that may be suitable for more than one fund or account. The investment opportunity may be limited, however, so that all funds or accounts for which the investment would be suitable may not be able to participate. Jackson Square has adopted procedures designed to allocate investments fairly across multiple funds or accounts. Certain of the accounts managed by the portfolio managers have performance-based fees. This compensation structure presents a potential conflict of interest. The portfolio managers have an incentive to manage such accounts so as to enhance their performance, to the possible detriment of other accounts for which the investment manager does not receive a performance-based fee. A portfolio manager’s management of personal accounts also may present certain conflicts of interest. Although Jackson Square’s code of ethics is designed to address these potential conflicts, there is no guarantee that it will do so. Investment personnel of the firm or its affiliates may be permitted to be commericially or professionally involved with an issuer of securities. Any potential conflicts of interest from such involvement would be monitored for compliance with the firm’s Code of Ethics.

3. Description of Compensation

Jackson Square’s investment professionals have remained together, bound by culture and the unique nature of the team’s research/portfolio manager role, for over a decade on average. Through various market and organizational circumstances over the years, the group has maintained a meritocracy and very strong pay-for-performance ethos that rewards positive impact to client portfolios. Each stock in each portfolio has two or more “sponsors” who have mathematical ownership of those names for performance attribution purposes (e.g., 60/40 or 50/50 responsibility splits). This stock-by-stock attribution can then be aggregated and the individual contributions of team members measured, down to the basis point, for each performance period measured: 1-, 3-, and 5-year, and since inception.

Aggregate compensation is ultimately driven by revenues. These in turn are correlated with assets under management (AUM), which ultimately correlates with performance over the long term, in a self-reinforcing cycle of better performance leading to more AUM (both via flows and appreciation) and greater revenues/compensation. Additionally, qualitative factors such as contribution to debates of other team members’ ideas are also considered in determining compensation. Certain employees, including eight members of the investment team, have equity ownership as part of their compensation.

In terms of the composition of compensation paid to the investment team, it is expected to be a combination of base salary, discretionary annual bonuses and for those members with equity, partnership equity distributions. Jackson Square believes this combination will have the proper incentives to award prudent long-term focus on building a stable and sustainable business while also rewarding professionals for superior relative interim results.

B-57


 

The Portfolio Manager is eligible to receive an incentive payment based on the revenues earned by Wellington Management from the Wellington Management Portfolio and generally each other account managed by the Portfolio Manager. The Portfolio Manager’s incentive payment relating to the Wellington Management Portfolio is linked to the net pre-tax performance of the portion of the Wellington Management Portfolio managed by the Portfolio Manager compared to the Russell 1000 Growth Index over one-, three-, and five-year periods, with an emphasis on five-year results. Wellington Management applies similar incentive compensation structures (although the benchmarks or peer groups, time periods and rates may differ) to other accounts managed by the Portfolio Manager, including accounts with performance fees.

Portfolio-based incentives across all accounts managed by an investment professional can, and typically do, represent a significant portion of an investment professional’s overall compensation; incentive compensation varies significantly by individual and can vary significantly from year to year. The Portfolio Manager may also be eligible for bonus payments based on his overall contribution to Wellington Management’s business operations. Senior management at Wellington Management may reward individuals as it deems appropriate based on other factors. Each Partner is eligible to participate in a Partner-funded tax-qualified retirement plan, the contributions to which are made pursuant to an actuarial formula. Mr. Shilling is a Partner.

2. Material Conflicts of Interest

Because each portfolio manager manages other accounts in addition to the William Blair Portfolio, conflicts of interest may arise in connection with the portfolio manager’s management of the William Blair Portfolio’s investments on the one hand and the investments of such other accounts on the other hand. However, William Blair has adopted policies and procedures designed to address such conflicts, including, among others, policies and procedures relating to allocation of investment opportunities, soft dollars, and aggregation of trades. Investment personnel of the firm or its affiliates may be permitted to be commercially or professionally involved with an issuer of securities. Any potential conflicts of interest from such involvement would be monitored for compliance with the firm’s Code of Ethics.

3. Description of Compensation

The compensation of William Blair portfolio managers is based on the firm’s mission: “to achieve success for its clients.” The portfolio managers are partners of William Blair, and each portfolio manager’s compensation consists of a fixed base salary, a share of the firm’s profits, and, in some instances, a discretionary bonus. The discretionary bonus, as well as any potential changes to the principals’ ownership stakes, is determined by the head of William Blair’s Investment Management division, subject to the approval of the firm’s Executive Committee, and is based entirely on a qualitative assessment rather than a formula. The discretionary bonus rewards the specific accomplishments in the prior year, including short-term and long-term investment performance, quality of research ideas, and other contributions to the

B-58


 

firm and its clients. Changes in ownership stake are based upon the portfolio manager’s sustained, multi-year contribution to long-term investment performance and to the firm’s revenue, profitability, intellectual capital, and brand reputation. The compensation process is a subjective one that takes into account the factors described in this section. Portfolio managers do not receive any direct compensation based upon the performance of any individual client account, and no indices are used to measure performance. In addition, there is no particular weighting or formula for evaluating the factors.

IV. International Portfolio

The Portfolio pays each of its independent third-party investment advisors a base fee plus or minus a performance adjustment. Each base fee, which is paid quarterly, is a percentage of average daily net assets managed by the advisor during the most recent fiscal quarter. The performance adjustment, also paid quarterly, is based on the cumulative total return of each advisor’s portion of the Portfolio relative to that of the MSCI ACWI ex USA Index over the preceding 36-month period.

During the fiscal years ended December 31, 2015 , 2016 , and 2017 , the International Portfolio incurred aggregate investment advisory fees of $3,501,000 (before a performance-based increase of $745,000), $3,271,000 (before a performance-based increase of $595,000), and $xx,000 (before a performance-based increase of $xx,000), respectively.

A. Baillie Gifford Overseas Ltd. (Baillie Gifford)

Baillie Gifford is an investment advisory firm founded in 1983. Baillie Gifford is wholly owned by a Scottish investment company, Baillie Gifford & Co. Founded in 1908, Baillie Gifford & Co., which is one of the largest independently owned investment management firms in the United Kingdom, manages money primarily for institutional clients.

1. Other Accounts Managed

James K. Anderson co-manages a portion of the International Portfolio; as of December 31, 2017 , the Portfolio held assets of $xx billion. As of December 31, 2017 , Mr. Anderson also led investment teams responsible for managing xx other registered investment companies with total assets of $xx billion (advisory fee based on account performance for xx of these accounts with total assets of $xx billion), xx other pooled investment vehicles with total assets of $xx billion (advisory fees not based on account performance), and xx other accounts with total assets of $xx billion (advisory fees based on account performance for xx of these accounts with total assets of $xx billion).

Thomas Coutts co-manages a portion of the International Portfolio; as of December 31, 2017 , the Portfolio held assets of $xx billion. As of December 31, 2017 , Mr. Coutts also managed xx other registered investment companies with total assets of $xx billion (advisory fee based on account performance for xx of these accounts with total assets of $xx billion), xx other pooled investment vehicles with total assets of $xx billion (advisory fees not based on account performance), and xx other accounts with total assets of $xx billion (none of which had advisory fees based on account performance).

2. Material Conflicts of Interest

At Baillie Gifford, individual portfolio managers may manage multiple accounts for multiple clients. In addition to mutual funds, these other accounts may include separate accounts, collective investment schemes, or offshore funds. Baillie Gifford manages potential conflicts between funds or with other types of accounts by implementing effective organizational and administrative arrangements to ensure that reasonable steps are taken to prevent the conflict giving rise to a material risk of damage to the interests of clients.

One area where a conflict of interest potentially arises is in the placing of orders for multiple clients and subsequent allocation of trades. Unless client-specific circumstances dictate otherwise, investment teams normally implement transactions in individual stocks for all clients with similar mandates at the same time. This aggregation of individual transactions can, of course, operate to the advantage or disadvantage of the clients involved in the order. When receiving orders from investment managers, traders at Baillie Gifford will generally treat order priority on a “first come, first served” basis, and any exceptions to this are permitted only in accordance with established policies. Baillie Gifford has also developed trade allocation systems and controls to ensure that no one client, regardless of type, is intentionally favored at the expense of another. Allocation policies are designed to address potential conflicts in situations where two or more funds or accounts participate in investment decisions involving the same securities. Investment personnel of

B-59


 

the firm or its affiliates may be permitted to be commercially or professionally involved with an issuer of securities. Any potential conflicts of interest from such involvement would be monitored for compliance with the firm’s Code of Ethics.

3. Description of Compensation

Mr. Anderson and Mr. Coutts are Partners of Baillie Gifford & Co. As such, each receives a base salary and a share of the partnership profits. The profit share is calculated as a percentage of total partnership profits based on seniority, role within Baillie Gifford & Co., and length of service. The basis for the profit share is detailed in the Baillie Gifford Partnership Agreement. The main staff benefits, such as pension schemes, are not available to partners, and therefore partners provide for benefits from their own personal funds.

B. Schroder Investment Management North America Inc. (Schroders)

Each of Schroders and Schroder Investment Management North America Limited (Schroder Limited), 31 Gresham Street, London, EC2V 7QA, England, is an indirect wholly owned subsidiary of Schroders plc, the ultimate parent of a large worldwide group of financial service companies with subsidiaries and branches and representative offices located in 27 countries. Schroders plc is a publicly owned holding company organized under the laws of England. Schroders and its affiliates specialize in providing investment management services.

Schroders Sub-advisory Agreement

On behalf of the Fund, Schroders has entered into a sub-advisory agreement with Schroder Limited pursuant to which Schroder Limited has primary responsibility for choosing investments for the International Portfolio. Under the terms of the sub-advisory agreement with the Fund, Schroders pays Schroder Limited fees equal to 59% of the management fee payable to Schroders under its management contract with the Fund.

1. Other Accounts Managed

Simon Webber manages a portion of the International Portfolio; as of December 31, 2017 , the Portfolio held assets of $xx billion. As of December 31, 2017 , Mr. Webber also managed xx other registered investment company with total assets of $xx million (advisory fees not based on account performance), xx other pooled investment vehicles with total assets of $xx million (advisory fees not based on account performance), and xx other accounts with total assets of $xx billion (advisory fees based on account performance for xx of these accounts with total assets of $xx million).

2. Material Conflicts of Interest

Whenever a portfolio manager of the Schroders Portfolio manages other accounts, potential conflicts of interest exist, including potential conflicts between the investment strategy of the Schroders Portfolio and the investment strategy of the other accounts. For example, in certain instances, a portfolio manager may take conflicting positions in a particular security for different accounts by selling a security for one account and continuing to hold it for another account. In addition, the fact that other accounts require the portfolio manager to devote less than all of his or her time to the Schroders Portfolio may be seen itself to constitute a conflict with the interest of the Schroders Portfolio.

A portfolio manager may also execute transactions for another fund or account at the direction of such fund or account that may adversely impact the value of securities held by the Schroders Portfolio. Securities selected for funds or accounts other than the Schroders Portfolio may outperform the securities selected for the Schroders Portfolio. Finally, if a portfolio manager identifies a limited investment opportunity that may be suitable for more than one fund or other account, the Schroders Portfolio may not be able to take full advantage of that opportunity because of an allocation of that opportunity across all eligible funds and accounts.

At Schroders, individual portfolio managers may manage multiple accounts for multiple clients. In addition to mutual funds, these other accounts may include separate accounts, collective trusts, or offshore funds. Certain of these accounts may pay a performance fee, and portfolio managers may have an incentive to allocate investment to these accounts.

Schroders manages potential conflicts between funds or with other types of accounts through allocation policies and procedures, internal review processes, and oversight by client directors. Schroders has developed trade allocation and client order priority systems and controls to ensure that no one client, regardless of type, is intentionally favored at the expense of another. Allocation policies are designed to address potential conflicts in situations where two or more funds or accounts participate in investment decisions involving the same securities.

B-60


 

The structure of each portfolio manager’s compensation may give rise to potential conflicts of interest. Each portfolio manager’s base pay tends to increase with additional and more complex responsibilities that include increased assets under management, which indirectly links compensation to sales.

Schroders has adopted certain compliance procedures that are designed to address these, and other, types of conflicts. However, there is no guarantee that such procedures will detect each and every situation in which a conflict arises.

3. Description of Compensation

Schroders’ portfolio managers are paid a combination of base salary and annual bonus, as well as the standard retirement, health, and welfare benefits available to all of our employees. Certain of the most senior managers also participate in a long-term incentive program. Mr. Webber receives compensation based on the factors discussed in this section.

Base salary is determined by reference to the level of responsibility inherent in the role and the experience of the incumbent, and is benchmarked annually against market data to ensure that Schroders is paying competitively. The base salary is subject to an annual review, and will increase if market movements make this necessary and/or if there has been an increase in the employee’s responsibilities. At more senior levels, base salaries tend to move less as the emphasis is increasingly on the discretionary bonus.

Bonuses for portfolio managers may be composed of an agreed contractual floor, a revenue component, and/or a discretionary component. Any discretionary bonus is determined by a number of factors. At a macro level the total amount available to spend is a function of the compensation to revenue ratio achieved by the firm globally. Schroders then assesses the performance of the division and of the team to determine the share of the aggregate bonus pool that is spent in each area. This focus on “team” maintains consistency and minimizes internal competition that may be detrimental to the interests of our clients. For individual portfolio managers, Schroders assesses the performance of its funds against the relevant benchmarks (which may be internally- and/or externally-based and are considered over a range of performance periods), the level of funds under management, and the level of performance fees generated. Schroders also reviews “softer” factors such as leadership, contribution to other parts of the business, and adherence to our corporate values of excellence, integrity, teamwork, passion, and innovation.

For those employees receiving significant bonuses, a part may be deferred in the form of Schroders plc stock. These employees may also receive part of the deferred award in the form of notional cash investments in a range of Schroders’ funds. These deferrals vest over a period of three years and ensure that the interests of the employee are aligned both with those of the shareholders and with those of investors. Over recent years Schroders has increased the level of deferred awards, and as a consequence these key employees have an increasing incentive to remain with Schroders as their store of unvested awards grows over time.

V. Small Company Growth Portfolio

The Portfolio pays ArrowMark Partners a base fee plus or minus a performance adjustment. The base fee, which is paid quarterly, is a percentage of average daily net assets managed by the advisor during the most recent fiscal quarter. The performance adjustment, also paid quarterly, is based on the cumulative total return of the advisor’s portion of the Portfolio relative to that of the Russell 2500 Growth Index over the preceding 60-month period. The Portfolio pays Vanguard on an at-cost basis with respect to its portion of the Small Company Growth Portfolio’s assets.

During the fiscal years ended December 31, 2015 , 2016 , and 2017 , the Small Company Growth Portfolio incurred aggregate investment advisory fees and expenses of approximately $2,099,000 (before a performance-based decrease of $97,000), $1,924,000, and $xx,000 (before a performance-based increase of $xx,000), respectively.

Of the aggregate fees and expenses previously described, the investment advisory expenses paid to Vanguard for the fiscal year ended December 31, 2017 , were approximately $xx,000 (representing an effective annual rate of 0.xx%). The investment advisory fees paid to ArrowMark Partners and Granahan Investment Management Inc. (Granahan) for the fiscal year ended December 31, 2017 , were $xx,000 (representing an effective annual rate of 0.xx%). Granahan is no longer an investment advisor for the Portfolio.

1. Other Accounts Managed

Chad Meade and Brian Schaub co-manage the Small Company Growth Portfolio; as of December 31, 2017 , the Portfolio held assets of $xx billion. As of December 31, 2017 , Mr. Meade and Mr. Schaub also co-managed xx other registered investment companies with total assets of $xx million, xx other pooled investment vehicle with total assets of $xx million, and xx other accounts with total assets of $xx million (none of which had advisory fees based on account performance).

2. Material Conflicts of Interest

Potential conflicts could include a portfolio manager’s knowledge about the size, timing, and possible market impact of a fund’s trades, whereby the portfolio manager could use this information to the advantage or disadvantage of another fund. A fund’s portfolio managers may be able to select or otherwise influence the selection of the brokers and dealers that are used to execute securities transactions for a fund. In addition to executing trades, some brokers and dealers provide managers with brokerage research services, which may result in the payment of higher brokerage fees than might have otherwise been available. These services may be more beneficial to certain funds or accounts than to others. Although the payment of brokerage commissions is subject to the requirement that the portfolio manager determine in good faith that the commissions are reasonable in relation to the value of the brokerage and research services provided to a fund, a portfolio manager’s decision as to the selection of brokers and dealers could potentially yield disproportionate costs and benefits among the individual funds.

A fund’s portfolio managers and analysts may also face other potential conflicts of interest in managing the funds, and the description above is not a complete description of every conflict that could be deemed to exist in managing both the funds and other accounts. In addition, the portfolio managers or analysts may also manage other accounts (including their personal assets or the assets of family members) in their personal capacity. The management of these accounts may also involve certain of the potential conflicts described above. Investment personnel, including the portfolio managers and analysts, are subject to restrictions on engaging in personal securities transactions pursuant to a Code of Ethics adopted by ArrowMark Partners and the funds. Although the potential for conflicts of interest may exist, the funds and ArrowMark Partners believe that they have established policies and procedures that seek to minimize potential conflicts of interest and to ensure that the purchase and sale of securities among all managed accounts are fairly and equitably executed and allocated.

3. Description of Compensation

Compensation for portfolio managers is designed to link the performance of each portfolio manager to shareholder objectives. All portfolio manager compensation through a base salary and bonus, is paid by ArrowMark Partners. The total compensation of a portfolio manager will be based on a combination of the pre-tax performance of each fund managed by the portfolio manager against applicable benchmark(s) as well as against its relevant peer group, with primary emphasis given to 3-year performance. Peer groups may include Lipper, Morningstar, and other customized universes of funds managed. Portfolio managers are incentivized for outperformance, but receive no extra compensation for being top decile performers, which minimizes the possibility of portfolio managers taking undue risk to be top performers.

B. Vanguard

Vanguard, through its Quantitative Equity Group, provides investment advisory services on an at-cost basis with respect to a portion of the Small Company Growth Portfolio’s assets. The compensation and other expenses of Vanguard’s advisory staff are allocated among the funds utilizing Vanguard’s advisory services.

VII. Balanced and High Yield Bond Portfolios

Wellington Management is a Delaware limited liability partnership with principal offices at 280 Congress Street, Boston, MA 02210. Wellington Management is a professional investment counseling firm that provides investment services to investment companies, employee benefit plans, endowments, foundations, and other institutions. Wellington Management and its predecessor organizations have provided investment advisory services for over 80 years. Wellington Management is owned by the partners of Wellington Management Group LLP , a Massachusetts limited liability partnership.

The Balanced Portfolio pays Wellington Management a base fee plus or minus a performance adjustment. The base fee, which is paid quarterly, is a percentage of average daily net assets under management during the most recent fiscal quarter. The base fee has breakpoints, which means that the percentage declines as assets go up. The performance adjustment, also paid quarterly, is based on the cumulative total return of the Portfolio relative to that of a Composite

B-64


 

Stock/Bond Index over the preceding 36-month period. The Index is a composite benchmark, weighted 65% in the Standard & Poor’s 500 Index and 35% in the Bloomberg Barclays U.S. Credit A or Better Bond Index.

During the fiscal years ended December 31, 2015 , 2016 , and 2017 , the Balanced Portfolio incurred investment advisory fees of $1,285,000 (before a performance-based decrease of $66,000), $1,307,000 (before a performance-based decrease of $136,000), and $xx,000 (before a performance-based decrease of $xx,000), respectively.

The High Yield Bond Portfolio pays Wellington Management a base fee. The base fee, which is paid quarterly, is a percentage of average daily net assets under management during the most recent fiscal quarter.

During the fiscal years ended December 31, 2015 , 2016 , and 2017 , the High Yield Bond Portfolio incurred investment advisory fees of approximately $326,000, $340,000, and $xx,000.

1. Other Accounts Managed

Edward P. Bousa manages the stock portion of the Balanced Portfolio; as of December 31, 2017 , the Portfolio held assets of $xx billion. As of December 31, 2017 , Mr. Bousa also managed xx other registered investment companies with total assets of $xx billion (advisory fee based on account performance for xx of these accounts with total assets of $xx billion), xx other pooled investment vehicles with total assets of $xx billion (advisory fee based on account performance for xx of these accounts with total assets of $xx million), and xx other accounts with total assets of $xx billion (advisory fees based on account performance for xx of these accounts with total assets of $xx million).

John C. Keogh, Loren L. Moran, and Michael E. Stack co-manage the bond portion of the Balanced Portfolio; as of December 31, 2017 , the Portfolio held assets of $xx billion.

2. Material Conflicts of Interest

Individual investment professionals at Wellington Management manage multiple accounts for multiple clients. These accounts may include mutual funds, separate accounts (assets managed on behalf of institutions, such as pension funds, insurance companies, foundations, or separately managed account programs sponsored by financial intermediaries), bank common trust accounts, and hedge funds. The Portfolios’ managers listed in the prospectus, who are primarily responsible for the day-to-day management of each Portfolio (Portfolio Managers), generally manage accounts in several different investment styles. These accounts may have investment objectives, strategies, time horizons, tax considerations, and risk profiles that differ from those of the relevant Portfolio. The Portfolio Managers make investment decisions for each account, including the relevant Portfolio, based on the investment objective, policies, practices, benchmarks, cash flows, tax, and other relevant investment considerations applicable to that account. Consequently, the Portfolio Managers may purchase or sell securities, including IPOs, for one account and not another account, and the performance of securities purchased for one account may vary from the performance of securities purchased for other accounts. Alternatively, these accounts may be managed in a similar fashion to the relevant Portfolio and thus the accounts may have similar, and in some cases nearly identical, objectives, strategies and/or holdings to that of the relevant Portfolio.

The Portfolio Managers or other investment professionals at Wellington Management may place transactions on behalf of other accounts that are directly or indirectly contrary to investment decisions made on behalf of the relevant Portfolio, or make investment decisions that are similar to those made for the relevant Portfolio, both of which have the potential to adversely impact the relevant Portfolio depending on market conditions. For example, an investment professional may purchase a security in one account while appropriately selling that same security in another account. Similarly, a Portfolio

B-65


 

Manager may purchase the same security for the relevant Portfolio and one or more other accounts at or about the same time, and in those instances the other accounts will have access to their respective holdings prior to the public disclosure of the relevant Portfolio’s holdings. In addition, some of these accounts have fee structures, including performance fees, which are or have the potential to be higher, in some cases significantly higher, than the fees Wellington Management receives for managing the Portfolios. Messrs. Bousa, Keogh, Stack, Reckmeyer, and Shilling also manage accounts which pay performance allocations to Wellington Management or its affiliates. Because incentive payments paid by Wellington Management to the Portfolio Managers are tied to revenues earned by Wellington Management and, where noted, to the performance achieved by the manager in each account, the incentives associated with any given account may be significantly higher or lower than those associated with other accounts managed by a given Portfolio Manager. Finally, the Portfolio Managers may hold shares or investments in other pooled investment vehicles and/or other accounts previously identified.

Wellington Management’s goal is to meet its fiduciary obligation to treat all clients fairly and provide high quality investment services to all of its clients. Wellington Management has adopted and implemented policies and procedures, including brokerage and trade allocation policies and procedures, that it believes address the conflicts associated with managing multiple accounts for multiple clients. In addition, Wellington Management monitors a variety of areas, including compliance with primary account guidelines, the allocation of IPOs, and compliance with the firm’s Code of Ethics, and places additional investment restrictions on investment professionals who manage hedge funds and certain other accounts. Furthermore, senior investment and business personnel at Wellington Management periodically review the performance of Wellington Management’s investment professionals. Although Wellington Management does not track the time an investment professional spends on a single account, Wellington Management does periodically assess whether an investment professional has adequate time and resources to effectively manage the investment professional’s various client mandates.

3. Description of Compensation

Wellington Management receives a fee based on the assets under management of each Portfolio as set forth in the Investment Advisory Agreements between Wellington Management and the Trust on behalf of each Portfolio. Wellington Management pays its investment professionals out of its total revenues, including the advisory fees earned with respect to each Portfolio. The following information relates to the fiscal year ended December 31, 2017 .

Wellington Management’s compensation structure is designed to attract and retain high-caliber investment professionals necessary to deliver high quality investment management services to its clients. Wellington Management’s compensation of the portfolio managers listed in the prospectus, who are primarily responsible for the day-to-day management of the Portfolios (“Portfolio Managers”) includes a base salary and incentive components. The base salary for each Portfolio Manager who is a partner (a “Partner”) of Wellington Management Group LLP , the ultimate holding company of Wellington Management, is generally a fixed amount that is determined by the managing partners of Wellington Management Group LLP . The base salary for the other portfolio managers is determined by their experience and performance in their role as a Portfolio Manager. Base salaries for Wellington Management’s employees are reviewed annually and may be adjusted based on the recommendation of a Portfolio Manager’s manager, using guidelines established by Wellington Management’s Compensation Committee, which has final oversight responsibility for base salaries of employees of the firm.

Each Portfolio Manager is eligible to receive an incentive payment based on the revenues earned by Wellington Management from the Portfolio managed by the Portfolio Manager and generally each other account managed by such Portfolio Manager. Mr. Bousa’s incentive payment relating to the Balanced Portfolio is linked to the net pre-tax performance of his portion of the Portfolio compared to the Standard & Poor’s 500 Index over one-, three-, and five-year periods, with an emphasis on five-year results. Wellington Management applies similar incentive compensation structures (although the benchmarks or peer groups, time periods and rates may differ) to other accounts managed by Mr. Bousa, including accounts with performance fees. The incentive paid to the other Portfolio Managers, which has no performance-related component, is based on the revenues earned by Wellington Management.

Portfolio-based incentives across all accounts managed by an investment professional can, and typically do, represent a significant portion of an investment professional’s overall compensation; incentive compensation varies significantly by individual and can vary significantly from year to year. The Portfolio Managers may also be eligible for bonus payments based on their overall contribution to Wellington Management’s business operations. Senior management at Wellington Management may reward individuals as it deems appropriate based on other factors. Each Partner is eligible to

participate in a Partner-funded tax-qualified retirement plan, the contributions to which are made pursuant to an actuarial formula. Messrs. Bousa, Stack, and Keogh are Partners.

VIII. Conservative Allocation, Equity Index, Global Bond Index, Mid-Cap Index, Moderate Allocation, Money Market, Real Estate Index, Short-Term Investment-Grade, Total Bond Market Index, Total International Stock Market Index, and Total Stock Market Index Portfolios

Vanguard, through its Equity Index Group, provides investment advisory services on an at-cost basis to the Equity Index, Mid-Cap Index, and Real Estate Index Portfolios. Vanguard, through its Fixed Income Group, provides investment advisory services on an at-cost basis to the Money Market, Short-Term Investment-Grade, and Total Bond Market Index Portfolios. The compensation and other expenses of Vanguard’s advisory staff are allocated among the funds utilizing these services.

During the fiscal years ended December 31, 2015 , 2016 , and 2017 , the Portfolios listed above (with the exception of Global Bond Index and Total International Stock Market Index Portfolios, which had not yet commenced operations) incurred the following approximate investment advisory expenses:

Vanguard Variable Insurance Fund Portfolio 2015 2016 2017
Equity Index Portfolio $621,000 $607,000 $xx
Mid-Cap Index Portfolio 203,000 206,000 xx
Money Market Portfolio 29,000 29,000 xx
Real Estate Index Portfolio 153,000 156,000 xx
Short-Term Investment-Grade Portfolio 130,000 142,000 xx
Total Bond Market Index Portfolio 278,000 316,000 xx

 

Vanguard also provides advisory services to the Fund-of-Fund Portfolios by (1) maintaining each Portfolio’s allocation to its underlying investments, and (2) providing advisory services to those underlying funds. The Portfolios benefit from the investment advisory services provided to the underlying funds and, as shareholders of those funds, indirectly bear a proportionate share of those funds’ at-cost advisory expenses. For more information about the investment advisory services provided to the underlying funds, please refer to each fund’s Statement of Additional Information.

2. Material Conflicts of Interest

At Vanguard, individual portfolio managers may manage multiple accounts for multiple clients. In addition to mutual funds, these accounts may include separate accounts, collective trusts, or offshore funds. Managing multiple funds or accounts may give rise to potential conflicts of interest including, for example, conflicts among investment strategies and conflicts in the allocation of investment opportunities. Vanguard manages potential conflicts between funds or accounts through allocation policies and procedures, internal review processes, and oversight by trustees and independent third parties. Vanguard has developed trade allocation procedures and controls to ensure that no one client, regardless of type, is intentionally favored at the expense of another. Allocation policies are designed to address potential conflicts in situations where two or more funds or accounts participate in investment decisions involving the same securities.

3. Description of Compensation

All named Vanguard portfolio managers are Vanguard employees. This section describes the compensation of the Vanguard employees who manage Vanguard mutual funds. As of December 31, 2017 , a Vanguard portfolio manager’s compensation generally consists of base salary, bonus, and payments under Vanguard’s long-term incentive compensation program. In addition, portfolio managers are eligible for the standard retirement benefits and health and welfare benefits available to all Vanguard employees. Also, certain portfolio managers may be eligible for additional retirement benefits under several supplemental retirement plans that Vanguard adopted in the 1980s to restore dollar-for-dollar the benefits of management employees that had been cut back solely as a result of tax law changes. These plans are structured to provide the same retirement benefits as the standard retirement plans.

In the case of portfolio managers responsible for managing multiple Vanguard funds or accounts, the method used to determine their compensation is the same for all funds and investment accounts. A portfolio manager’s base salary is determined by the manager’s experience and performance in the role, taking into account the ongoing compensation benchmark analyses performed by Vanguard’s Human Resources Department. A portfolio manager’s base salary is generally a fixed amount that may change as a result of an annual review, upon assumption of new duties, or when a market adjustment of the position occurs.

B-68


 

A portfolio manager’s bonus is determined by a number of factors. One factor is gross, pre-tax performance of a fund relative to expectations for how the fund should have performed, given the fund’s investment objective, policies, strategies, and limitations, and the market environment during the measurement period. This performance factor is not based on the amount of assets held in the fund’s portfolio. For the Short-Term Investment-Grade Portfolio, the performance factor depends on how successfully the portfolio manager outperforms these expectations and maintains the risk parameters of the fund over a three-year period. For the Conservative Allocation and Moderate Allocation Portfolios, the performance factor depends on how successfully the portfolio manager outperforms each Portfolio’s composite index and maintains the risk parameters of the Portfolio over a three-year period. For the Equity Index, Mid-Cap Index, Real Estate Index, Total Bond Market Index, and Total Stock Market Index Portfolios, the performance factor depends on how closely the portfolio manager tracks the Portfolio’s benchmark index over a one-year period. For the Equity Income and Small Company Growth Portfolios, the performance factor depends on how successfully the portfolio manager maintains the risk parameters of the fund and outperforms the relevant peer group that invests in the market sectors in which the fund is permitted to invest over a three-year period. For the Money Market Portfolio, the performance factor depends on how successfully the portfolio manager maintains the credit quality of the fund and, consequently, how the fund performs relative to the expectations described above over a one-year period. Additional factors include the portfolio manager’s contributions to the investment management functions within the sub-asset class, contributions to the development of other investment professionals and supporting staff, and overall contributions to strategic planning and decisions for the investment group. The target bonus is expressed as a percentage of base salary. The actual bonus paid may be more or less than the target bonus, based on how well the manager satisfies the objectives previously described. The bonus is paid on an annual basis.

Under the long-term incentive compensation program, all full-time employees receive a payment from Vanguard’s long-term incentive compensation plan based on their years of service, job level, and, if applicable, management responsibilities. Each year, Vanguard’s independent directors determine the amount of the long-term incentive compensation award for that year based on the investment performance of the Vanguard funds relative to competitors and Vanguard’s operating efficiencies in providing services to the Vanguard funds.

Ownership of Securities in the Portfolios

The Portfolios are mutual funds used solely as investment options for annuity or life insurance contracts offered by insurance companies, which can only be purchased through a contract offered by an insurance company. Accordingly, the Portfolios that make up the Fund are suitable investments for only a limited subset of investors. As of December 31, 2017 , Mr. Keogh, through investing in Vanguard Variable Annuity, indirectly had investments in the Balanced Portfolio within the $xx,001-$xx,000 range. No other named portfolio managers had indirect investments with any of the Portfolios.

Duration and Termination of Investment Advisory Agreements

The current investment advisory agreements with the unaffiliated advisors (other than ArrowMark Partners and Jackson Square) are renewable for successive one-year periods, only if (1) each renewal is specifically approved by a vote of the Fund’s board of trustees, including the affirmative votes of a majority of the trustees who are not parties to the agreement or “interested persons” (as defined in the 1940 Act) of any such party, cast in person at a meeting called for the purpose of considering such approval, or (2) each renewal is specifically approved by a vote of a majority of the Portfolio’s outstanding voting securities.

The initial investment advisory agreements with ArrowMark Partners and Jackson Square are binding for a two-year period. At the end of that time, the agreements will become renewable for successive one-year periods, subject to the above conditions.

An agreement is automatically terminated if assigned, and may be terminated without penalty at any time either (1) by vote of the board of trustees of the Fund upon sixty (60) days’ written notice to the advisor (thirty (30) days’ written notice for ArrowMark Partners; Barrow, Hanley; Jackson Square; PRIMECAP; William Blair and Wellington Management (for the Balanced, Equity Income, and Growth Portfolios); (2) by a vote of a majority of the Portfolio’s outstanding voting securities upon 60 days’ written notice to the advisor (30 days’ written notice for ArrowMark Partners; Barrow, Hanley; Jackson Square; PRIMECAP; William Blair and Wellington Management (for the Balanced, Equity Income, and Growth Portfolios); or (3) by the advisor upon ninety (90) days’ written notice to the Portfolio.

Vanguard provides at-cost investment advisory services to the Conservative Allocation, Equity Index, Global Bond Index, Mid-Cap Index, Moderate Allocation, Money Market, Real Estate Index, Short-Term Investment-Grade, Total Bond Market Index, Total International Stock Market Index, and Total Stock Market Index Portfolios, and for a portion of the assets in the Equity Income and Small Company Growth Portfolios, pursuant to the terms of the Fifth Amended and Restated Funds’ Service Agreement. This agreement will continue in full force and effect until terminated or amended by mutual agreement of the Vanguard funds and Vanguard.

PORTFOLIO TRANSACTIONS

The advisors decide which securities to buy and sell on behalf of a Portfolio and then selects the brokers or dealers that will execute the trades on an agency basis or the dealers with whom the trades will be effected on a principal basis. For each trade, the advisor must select a broker-dealer that it believes will provide “best execution.” Best execution does not necessarily mean paying the lowest spread or commission rate available. In seeking best execution, the SEC has said that an advisor should consider the full range of a broker-dealer’s services. The factors considered by the advisor in seeking best execution include, but are not limited to, the broker-dealer’s execution capability; clearance and settlement services; commission rate; trading expertise; willingness and ability to commit capital; ability to provide anonymity; financial responsibility; reputation and integrity; responsiveness; access to underwritten offerings and secondary markets; and access to company management, as well as the value of any research provided by the broker-dealer. In assessing which broker-dealer can provide best execution for a particular trade, the advisor also may consider the timing and size of the order and available liquidity and current market conditions. Subject to applicable legal requirements, the advisor may select a broker based partly on brokerage or research services provided to the advisor and its clients, including the Portfolio. The advisor may cause the Portfolio to pay a higher commission than other brokers would charge if the advisor determines in good faith that the amount of the commission is reasonable in relation to the value of services provided. An advisor also may receive brokerage or research services from broker-dealers that are provided at no charge in recognition of the volume of trades directed to the broker. To the extent research services or products may be a factor in selecting brokers, services and products may include written research reports analyzing performance or securities; discussions with research analysts; meetings with corporate executives to obtain oral reports on company performance; market data; and other products and services that will assist the advisor in its investment decision-making process. The research services provided by brokers through which a Portfolio effects securities transactions may be used by the advisor in servicing all of its accounts, and some of the services may not be used by the advisor in connection with the Portfolio.

The Conservative Allocation, Global Bond Index, Moderate Allocation, Total International Stock Market Index, and Total Stock Market Index Portfolios each will purchase and sell conventional shares (i.e., not exchange-traded) of the underlying Vanguard funds by dealing directly with the issuer of the underlying funds. The Portfolios will incur no brokerage commissions for these transactions. To the extent a Portfolio purchases and sells ETF Shares of an underlying fund, the Portfolio will pay brokerage commissions.

Balanced (bond portion only), High Yield Bond, Money Market, Short-Term Investment-Grade, and Total Bond Market Index Portfolios

The types of securities in which the money market and bond Portfolios invest are generally purchased and sold through principal transactions, meaning that the Portfolios normally purchase securities directly from the issuer or a primary market-maker acting as principal for the securities on a net basis. Explicit brokerage commissions are not paid on these transactions, although purchases of new issues from underwriters of bonds typically include a commission or concession paid by the issuer to the underwriter, and purchases from dealers serving as market-makers typically include a dealer’s markup (i.e., a spread between the bid and the asked prices).

As previously explained, the types of securities that the Portfolios purchase do not normally involve the payment of explicit brokerage commissions. If any such brokerage commissions are paid, however, the advisor will evaluate their reasonableness by considering (1) historical commission rates; (2) rates which other institutional investors are paying, based upon publicly available information; (3) rates quoted by brokers and dealers; (4) the size of a particular transaction, in terms of the number of shares, dollar amount, and number of clients involved; (5) the complexity of a particular transaction in terms of both execution and settlement; (6) the level and type of business done with a particular firm over a period of time; and (7) the extent to which the broker or dealer has capital at risk in the transaction.

All Portfolios

During the fiscal years ended December 31, 2015 , 2016 , and 2017 , the Portfolios (except Global Bond Index and Total International Stock Market Index Portfolios, which had not yet commenced operations) paid the following approximate amounts in brokerage commissions:

Portfolio 2015 2016 2017
Balanced Portfolio 1 $268,000 $456,000 $xx
Capital Growth Portfolio 2 152,000 109,000 xx
Conservative Allocation Portfolio 0 0 xx
Diversified Value Portfolio 3 208,000 160,000 xx
Equity Income Portfolio 4 88,000 189,000 xx
Equity Index Portfolio 27,000 30,000 xx
Growth Portfolio 103,000 116,000 xx
High Yield Bond Portfolio 0 Less than 1,000 xx
International Portfolio 959,000 781,000 xx
Mid-Cap Index Portfolio 4 18,000 31,000 xx
Moderate Allocation Portfolio 0 0 xx
Money Market Portfolio 0 0 xx
Real Estate Index Portfolio 43,000 47,000 xx
Short-Term Investment-Grade Portfolio 5 49,000 43,000 xx
Small Company Growth Portfolio 680,000 1,188,000 xx
Total Bond Market Index Portfolio 0 0 xx
Total Stock Market Index Portfolio 1,000 0 xx
1 The increase in brokerage commissions for the Portfolio in 2015 was the result of a modest increase in trading activity and a rise in non-electronic
trading directly with the trading desk.      
2 The fluctuations in brokerage commissions for the Portfolio for the years shown are a result of changing market conditions during those years,
which impacted the frequency of portfolio transactions.      
3 The increase in brokerage commissions for the Portfolio in 2016 was primarily brought on by shifts in market dynamics as well as a change in
the Portfolio manager.      
4 The increase in brokerage commissions for the Portfolio in 2015 was the result of an increase in trading activity.  
5 The increase in brokerage commissions for the Portfolio in 2016 was the result of an increased use of derivatives.  

 

Some securities that are considered for investment by a Portfolio may also be appropriate for other Vanguard funds or for other clients served by the advisors. If such securities are compatible with the investment policies of the Portfolio and one or more of an advisor’s other clients, and are considered for purchase or sale at or about the same time, then transactions in such securities may be aggregated by that advisor and the purchased securities or sale proceeds may be allocated among the participating Vanguard funds and the other participating clients of the advisor in a manner deemed equitable by the advisor. Although there may be no specified formula for allocating such transactions, the allocation methods used, and the results of such allocations, will be subject to periodic review by the Fund’s board of trustees.

The ability of Vanguard and external advisors to purchase or dispose of investments in regulated industries, certain derivatives markets, certain international markets, and certain issuers that limit ownership by a single shareholder or group of related shareholders, or to exercise rights on behalf of a Portfolio, may be restricted or impaired because of limitations on the aggregate level of investment unless regulatory or corporate consents or ownership waivers are obtained. As a result, Vanguard and external advisors on behalf of a Portfolio may be required to limit purchases, sell existing investments, or otherwise restrict or limit the exercise of shareholder rights by the Portfolio, including voting rights. If a Portfolio is required to limit its investment in a particular issuer, the Portfolio may seek to obtain economic exposure to that issuer through alternative means, such as through a derivative, which may be more costly than owning securities of the issuer directly.

As of December 31, 2017, each Portfolio (except Global Bond Index and Total International Stock Market Index Portfolios, which had not yet commenced operations) held securities of its “regular brokers or dealers,” as that term is defined in Rule 10b-1 of the 1940 Act, as follows:

PROXY VOTING GUIDELINES

The Board of Trustees (the Board) of each Vanguard fund has adopted proxy voting procedures and guidelines to govern proxy voting by the fund. The Board has delegated responsibility for monitoring proxy voting activities to the Investment Stewardship Oversight Committee (the Committee), made up of senior officers of Vanguard and subject to the operating procedures and guidelines described below. The Committee reports directly to the Board. Vanguard is subject to these procedures and guidelines to the extent that they call for Vanguard to administer the voting process and implement the resulting voting decisions, and for these purposes the guidelines have also been approved by the Board of Directors of Vanguard.

The overarching objective in voting is simple: to support proposals and director nominees that maximize the value of a fund’s investments—and those of fund shareholders—over the long term. Although the goal is simple, the proposals the funds receive are varied and frequently complex. As such, the guidelines adopted by the Board provide a rigorous framework for assessing each proposal. Under the guidelines, each proposal must be evaluated on its merits, based on the particular facts and circumstances as presented.

For ease of reference, the procedures and guidelines often refer to all funds. However, our processes and practices seek to ensure that proxy voting decisions are suitable for individual funds. For most proxy proposals, particularly those involving corporate governance, the evaluation will result in the same position being taken across all of the funds and the funds voting as a block. In some cases, however, a fund may vote differently, depending upon the nature and objective of the fund, the composition of its portfolio, and other factors.

The guidelines do not permit the Board to delegate voting responsibility to a third party that does not serve as a fiduciary for the funds. Because many factors bear on each decision, the guidelines incorporate factors the Committee should consider in each voting decision. A fund may refrain from voting some or all of its shares or vote in a particular way if doing so would be in the fund’s and its shareholders’ best interests. These circumstances may arise, for example, if the expected cost of voting exceeds the expected benefits of voting, if exercising the vote would result in the imposition of trading or other restrictions, or if a fund (or all Vanguard funds in the aggregate) were to own more than the permissible

B-73


 

maximum percentage of a company’s stock (as determined by the company’s governing documents or by applicable law, regulation, or regulatory agreement).

In evaluating proxy proposals, we consider information from many sources, including, but not limited to, the investment advisor for the fund, the management or shareholders of a company presenting a proposal, and independent proxy research services. We will give substantial weight to the recommendations of the company’s board, absent guidelines or other specific facts that would support a vote against management. In all cases, however, the ultimate decision rests with the members of the Committee, who are accountable to the fund’s Board.

While serving as a framework, the following guidelines cannot contemplate all possible proposals with which a fund may be presented. In the absence of a specific guideline for a particular proposal (e.g., in the case of a transactional issue or contested proxy), the Committee will evaluate the issue and cast the fund’s vote in a manner that, in the Committee’s view, will maximize the value of the fund’s investment, subject to the individual circumstances of the fund.

I.       The Board of Directors
A.       Election of directors

Good governance starts with a majority-independent board, whose key committees are made up entirely of independent directors. As such, companies should attest to the independence of directors who serve on the Compensation, Nominating, and Audit committees. In any instance in which a director is not categorically independent, the basis for the independence determination should be clearly explained in the proxy statement.

Although the funds will generally support the board’s nominees, the following factors will be taken into account in determining each fund’s vote:

Factors For Approval

Nominated slate results in board made up of a majority of independent directors.

All members of Audit, Nominating, and Compensation committees are independent of management.

Factors Against Approval

Nominated slate results in board made up of a majority of non-independent directors.

Audit, Nominating, and/or Compensation committees include non-independent members.

Incumbent board member failed to attend at least 75% of meetings in the previous year.

Actions of committee(s) on which nominee serves are inconsistent with other guidelines (e.g., excessive equity grants, substantial non-audit fees, lack of board independence).

Actions of committee(s) on which nominee serves demonstrate serious failures of governance (e.g., unilaterally acting to significantly reduce shareholder rights, failure to respond to previous vote results for directors and shareholder proposals).

 
 

B. Contested director elections

 

In the case of contested board elections, we will evaluate the nominees’ qualifications, the performance of the incumbent board, and the rationale behind the dissidents’ campaign, to determine the outcome that we believe will maximize shareholder value.

C. Classified boards

The funds will generally support proposals to declassify existing boards (whether proposed by management or shareholders), and will block efforts by companies to adopt classified board structures in which only part of the board is elected each year.

D. Proxy access

We believe that long-term investors may benefit from having proxy access, or the opportunity to place director nominees on a company’s proxy ballot. In our view, this improves shareholders’ ability to participate in director elections while potentially enhancing boards’ accountability and responsiveness to shareholders.

B-74


 

That said, we also believe that proxy access provisions should be appropriately limited to avoid abuse by investors who lack a meaningful long-term interest in the company. As such, we generally believe that a shareholder or group of shareholders representing 3% of a company’s outstanding shares held for at least three years should be able to nominate directors for up to 20% of the seats on the board.

We will review proposals regarding proxy access case by case. The funds will be most likely to support access provisions with the terms described above, but they may support different thresholds based on a company’s other governance provisions, as well as other relevant factors.

II. Approval of Independent Auditors

The relationship between the company and its auditors should be limited primarily to the audit, although it may include certain closely related activities that do not, in the aggregate, raise any appearance of impaired independence. The funds will generally support management’s recommendation for the ratification of the auditor, except in instances in which audit and audit-related fees make up less than 50% of the total fees paid by the company to the audit firm. We will evaluate on a case-by-case basis instances in which the audit firm has a substantial non-audit relationship with the company (regardless of its size relative to the audit fee) to determine whether independence has been compromised.

III.       Compensation Issues
A.       Stock-based compensation plans

Appropriately designed stock-based compensation plans, administered by an independent committee of the board and approved by shareholders, can be an effective way to align the interests of long-term shareholders with the interests of management, employees, and directors. The funds oppose plans that substantially dilute their ownership interest in the company, provide participants with excessive awards, or have inherently objectionable structural features.

An independent compensation committee should have significant latitude to deliver varied compensation to motivate the company’s employees. However, we will evaluate compensation proposals in the context of several factors (a company’s industry, market capitalization, competitors for talent, etc.) to determine whether a particular plan or proposal balances the perspectives of employees and the company’s other shareholders. We will evaluate each proposal on a case-by-case basis, taking all material facts and circumstances into account.

The following factors will be among those considered in evaluating these proposals:

Factors For Approval

Company requires senior executives to hold a minimum amount
of company stock (frequently expressed as a multiple of salary).
Company requires stock acquired through equity awards to be
held for a certain period of time.
Compensation program includes performance-vesting awards,
indexed options, or other performance-linked grants.
Concentration of equity grants to senior executives is limited
(indicating that the plan is very broad-based).
Stock-based compensation is clearly used as a substitute for
cash in delivering market-competitive total pay.

B. Bonus plans

Factors Against Approval

Total potential dilution (including all stock-based plans) exceeds 15% of
shares outstanding.
Annual equity grants have exceeded 2% of shares outstanding.

Plan permits repricing or replacement of options without
shareholder approval.
Plan provides for the issuance of reload options.

Plan contains automatic share replenishment (evergreen) feature.

Bonus plans, which must be periodically submitted for shareholder approval to qualify for deductibility under Section 162(m) of the IRC, should have clearly defined performance criteria and maximum awards expressed in dollars. Bonus plans with awards that are excessive, in both absolute terms and relative to a comparative group, generally will not be supported.

C. Employee stock purchase plans

The funds will generally support the use of employee stock purchase plans to increase company stock ownership by employees, provided that shares purchased under the plan are acquired for no less than 85% of their market value and that shares reserved under the plan amount to less than 5% of the outstanding shares.

B-75


 

D. Advisory votes on executive compensation (Say on Pay)

In addition to proposals on specific equity or bonus plans, the funds are required to cast advisory votes approving many companies’ overall executive compensation plans (so-called Say on Pay votes). In evaluating these proposals, we consider a number of factors, including the amount of compensation that is at risk, the amount of equity-based compensation that is linked to the company’s performance, and the level of compensation as compared to industry peers. The funds will generally support pay programs that demonstrate effective linkage between pay and performance over time and that provide compensation opportunities that are competitive relative to industry peers. On the other hand, pay programs in which significant compensation is guaranteed or insufficiently linked to performance will be less likely to earn our support.

E. Executive severance agreements (golden parachutes)

Although executives’ incentives for continued employment should be more significant than severance benefits, there are instances—particularly in the event of a change in control—in which severance arrangements may be appropriate. Severance benefits payable upon a change of control AND an executive’s termination (so-called “double trigger” plans) are generally acceptable to the extent that benefits paid do not exceed three times salary and bonus. Arrangements in which the benefits exceed three times salary and bonus should be justified and submitted for shareholder approval. We do not generally support guaranteed severance absent a change in control or arrangements that do not require the termination of the executive (so-called “single trigger” plans).

IV. Corporate Structure and Shareholder Rights

The exercise of shareholder rights, in proportion to economic ownership, is a fundamental privilege of stock ownership that should not be unnecessarily limited. Such limits may be placed on shareholders’ ability to act by corporate charter or by-law provisions, or by the adoption of certain takeover provisions. In general, the market for corporate control should be allowed to function without undue interference from these artificial barriers.

The funds’ positions on a number of the most commonly presented issues in this area are as follows:

A.       Shareholder rights plans (poison pills)
A       company’s adoption of a so-called poison pill effectively limits a potential acquirer’s ability to buy a controlling interest

without the approval of the target’s board of directors. Such a plan, in conjunction with other takeover defenses, may serve to entrench incumbent management and directors. However, in other cases, a poison pill may force a suitor to negotiate with the board and result in the payment of a higher acquisition premium.

In general, shareholders should be afforded the opportunity to approve shareholder rights plans within a year of their adoption. This provides the board with the ability to put a poison pill in place for legitimate defensive purposes, subject to subsequent approval by shareholders. In evaluating the approval of proposed shareholder rights plans, we will consider the following factors:

Factors For Approval Factors Against Approval
Plan is relatively short term (3-5 years). Plan is long term (>5 years).
Plan requires shareholder approval for renewal. Renewal of plan is automatic or does not require shareholder approval.
Plan incorporates review by a committee of independent Board with limited independence.
directors at least every three years (so-called TIDE provisions).  
Ownership trigger is reasonable (15-20%). Ownership trigger is less than 15%.
Highly independent, non-classified board. Classified board.
Plan includes permitted-bid/qualified-offer feature (chewable  
pill) that mandates a shareholder vote in certain situations.  
 
B. Increase in authorized shares  

 

The funds are supportive of companies seeking to increase authorized share amounts that do not potentially expose shareholders to excessive dilution. We will generally approve increases of up to 50% of the current share authorization, but will also consider a company’s specific circumstances and market practices.

B-76


 

C. Cumulative voting

The funds are generally opposed to cumulative voting under the premise that it allows shareholders a voice in director elections that is disproportionate to their economic investment in the corporation.

D. Supermajority vote requirements

The funds support shareholders’ ability to approve or reject matters presented for a vote based on a simple majority. Accordingly, the funds will support proposals to remove supermajority requirements and oppose proposals to impose them.

E. Right to call meetings and act by written consent

The funds support shareholders’ right to call special meetings of the board (for good cause and with ample representation) and to act by written consent. The funds will generally vote for proposals to grant these rights to shareholders and against proposals to abridge them.

F. Confidential voting

The integrity of the voting process is enhanced substantially when shareholders (both institutions and individuals) can vote without fear of coercion or retribution based on their votes. As such, the funds support proposals to provide confidential voting.

G. Dual classes of stock

We are opposed to dual class capitalization structures that provide disparate voting rights to different groups of shareholders with similar economic investments. We will oppose the creation of separate classes with different voting rights and will support the dissolution of such classes.

V. Corporate and Social Policy Issues

We vote case by case on all environmental and social proposals. We evaluate these resolutions in the context of our view that a company’s board has ultimate responsibility for providing effective ongoing oversight of relevant sector- and company-specific risks, including those related to environmental and social matters. We evaluate each proposal on its merits and support those where we believe there is a logically demonstrable linkage between the specific proposal and long-term shareholder value. Some of the factors considered when evaluating these proposals include the materiality of the issue, the quality of the current disclosure and business practices, and any progress by the company toward the adoption of best practices and/or industry norms.

VI. Voting in Foreign Markets

Corporate governance standards, disclosure requirements, and voting mechanics vary greatly among the markets outside the United States in which the funds may invest. Each fund’s votes will be used, where applicable, to advocate for improvements in governance and disclosure by each fund’s portfolio companies. We will evaluate issues presented to shareholders for each fund’s foreign holdings in the context with the guidelines described above, as well as local market standards and best practices. The funds will cast their votes in a manner believed to be philosophically consistent with these guidelines, while taking into account differing practices by market. In addition, there may be instances in which the funds elect not to vote, as described below.

Many foreign markets require that securities be “blocked” or reregistered to vote at a company’s meeting. Absent an issue of compelling economic importance, we will generally not subject the fund to the loss of liquidity imposed by these requirements.

The costs of voting (e.g., custodian fees, vote agency fees) in foreign markets may be substantially higher than for U.S. holdings. As such, the fund may limit its voting on foreign holdings in instances in which the issues presented are unlikely to have a material impact on shareholder value.

B-77


 

VII. Voting Shares of a Company that has an Ownership Limitation

Certain companies have provisions in their governing documents that restrict stock ownership in excess of a specified limit. Typically, these ownership restrictions are included in the governing documents of real estate investment trusts, but may be included in other companies’ governing documents.

A company’s governing documents normally allow the company to grant a waiver of these ownership limits, which would allow a fund (or all Vanguard-advised funds) to exceed the stated ownership limit. Sometimes a company will grant a waiver without restriction. From time to time, a company may grant a waiver only if a fund (or funds) agrees to not vote the company’s shares in excess of the normal specified limit. In such a circumstance, a fund may refrain from voting shares if owning the shares beyond the company’s specified limit is in the best interests of the fund and its shareholders.

In addition, applicable law may require prior regulatory approval to permit ownership of certain regulated issuer’s voting securities above certain limits or may impose other restrictions on owners of more than a certain percentage of a regulated issuer’s voting shares. The Board has authorized the funds to vote shares above these limits in the same proportion as votes cast by the issuer’s entire shareholder base (i.e., mirror vote) or to refrain from voting excess shares if mirror voting is not practicable. For example, rules administered by the Board of Governors of the Federal Reserve System (the FRB) generally require that a person seeking to own more than 10% of a bank regulated by the FRB seek prior approval. Vanguard has obtained regulatory approval that allows Vanguard funds to own up to 15% of a class of a bank’s outstanding voting shares without seeking prior regulatory approval, provided the funds’ shares in excess of 10% are mirror voted or not voted at all.

These ownership limits may be applied at the individual fund level, across all Vanguard-advised funds, or across all Vanguard funds, regardless of whether they are advised by Vanguard.

VIII. Voting on a Fund’s Holdings of Other Vanguard Funds

Certain Vanguard funds (owner funds) may, from time to time, own shares of other Vanguard funds (underlying funds). If an underlying fund submits a matter to a vote of its shareholders, votes for and against such matters on behalf of the owner funds will be cast in the same proportion as the votes of the other shareholders in the underlying fund.

IX. Investment Stewardship

The Board has delegated the day-to-day operation of the funds’ proxy voting process to the Investment Stewardship team (Investment Stewardship), which the Committee oversees. Although most votes will be determined, subject to the individual circumstances of each fund, by reference to the guidelines as separately adopted by each of the funds, there may be circumstances when Investment Stewardship will refer proxy issues to the Committee for consideration. In addition, at any time, the Board has the authority to vote proxies, when, at the Board’s or the Committee’s discretion, such action is warranted.

Investment Stewardship performs the following functions: (1) managing and conducting due diligence of proxy voting vendors; (2) reconciling share positions; (3) analyzing proxy proposals using factors described in the guidelines; (4) determining and addressing potential or actual conflicts of interest that may be presented by a particular proxy; and (5) voting proxies. Investment Stewardship also prepares periodic and special reports to the Board, and any proposed amendments to the procedures and guidelines.

X. The Investment Stewardship Oversight Committee

The Board, including a majority of the independent trustees, appoints the members of the Committee who are senior officers of Vanguard.

The Committee does not include anyone whose primary duties include external client relationship management or sales. This clear separation between the proxy voting and client relationship functions is intended to eliminate any potential conflict of interest in the proxy voting process. In the unlikely event that a member of the Committee believes he or she might have a conflict of interest regarding a proxy vote, that member must recuse himself or herself from the committee meeting at which the matter is addressed, and not participate in the voting decision.

B-78


 

The Committee works with Investment Stewardship to provide reports and other guidance to the Board regarding proxy voting by the funds. The Committee has an obligation to conduct its meetings and exercise its decision-making authority subject to the fiduciary standards of good faith, fairness, and Vanguard’s Code of Ethics. The Committee shall authorize proxy votes that the Committee determines, at its sole discretion, to be in the best interests of each fund’s shareholders. In determining how to apply the guidelines to a particular factual situation, the Committee may not take into account any interest that would conflict with the interest of fund shareholders in maximizing the value of their investments.

The Board may review these procedures and guidelines and modify them from time to time. A summary of the procedures and guidelines is available on Vanguard’s website at vanguard.com .

You may obtain a free copy of a report that details how the funds voted the proxies relating to the portfolio securities held by the funds for the prior 12-month period ended June 30 by logging on to Vanguard’s website at vanguard.com or the SEC’s website at www.sec.gov.

DESCRIPTION OF BOND RATINGS

Moody’s Rating Symbols

The following describe characteristics of the global long-term (original maturity of 1 year or more) bond ratings provided by Moody’s Investors Service, Inc. (Moody’s):

Aaa —Judged to be obligations of the highest quality, they are subject to the lowest level of credit risk.

Aa —Judged to be obligations of high quality, they are subject to very low credit risk. Together with the Aaa group, they make up what are generally known as high-grade bonds.

A —Judged to be upper-medium-grade obligations, they are subject to low credit risk.

Baa —Judged to be medium-grade obligations, subject to moderate credit risk, they may possess certain speculative characteristics.

Ba —Judged to be speculative obligations, they are subject to substantial credit risk.

B —Considered to be speculative obligations, they are subject to high credit risk.

Caa —Judged to be speculative obligations of poor standing, they are subject to very high credit risk.

Ca —Viewed as highly speculative obligations, they are likely in, or very near, default, with some prospect of recovery of principal and interest.

C —Viewed as the lowest rated obligations, they are typically in default, with little prospect for recovery of principal and interest.

Moody’s also supplies numerical indicators (1, 2, and 3) to rating categories. The modifier 1 indicates that the security is in the higher end of its rating category, the modifier 2 indicates a mid-range ranking, and the modifier 3 indicates a ranking toward the lower end of the category.

The following describe characteristics of the global short-term (original maturity of 13 months or less) bond ratings provided by Moody’s. This ratings scale also applies to U.S. municipal tax-exempt commercial paper.

Prime-1 (P-1) —Judged to have a superior ability to repay short-term debt obligations.

Prime-2 (P-2) —Judged to have a strong ability to repay short-term debt obligations.

B-79


 

Prime-3 (P-3) —Judged to have an acceptable ability to repay short-term debt obligations.

Not Prime (NP) —Cannot be judged to be in any of the prime rating categories.

The following describe characteristics of the U.S. municipal short-term bond ratings provided by Moody’s:

Moody’s ratings for state and municipal notes and other short-term (up to 3 years) obligations are designated Municipal Investment Grade (MIG).

MIG 1 —Indicates superior quality, enjoying the excellent protection of established cash flows, liquidity support, and broad-based access to the market for refinancing.

MIG 2 —Indicates strong credit quality with ample margins of protection, although not as large as in the preceding group.

MIG 3 —Indicates acceptable credit quality, with narrow liquidity and cash-flow protection and less well-established market access for refinancing.

SG —Indicates speculative credit quality with questionable margins of protection.

Standard and Poor’s Rating Symbols

The following describe characteristics of the long-term (original maturity of 1 year or more) bond ratings provided by Standard and Poor’s:

AAA —These are the highest rated obligations. The capacity to pay interest and repay principal is extremely strong.

AA —These also qualify as high-grade obligations. They have a very strong capacity to pay interest and repay principal, and they differ from AAA issues only in small degree.

A —These are regarded as upper-medium-grade obligations. They have a strong capacity to pay interest and repay principal although they are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than debt in higher-rated categories.

BBB —These are regarded as having an adequate capacity to pay interest and repay principal. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity in this regard. This group is the lowest that qualifies for commercial bank investment.

BB, B, CCC, CC, and C —These obligations range from speculative to significantly speculative with respect to the capacity to pay interest and repay principal. BB indicates the lowest degree of speculation and C the highest.

D —These obligations are in default, and payment of principal and/or interest is likely in arrears.

The ratings from AA to CCC may be modified by the addition of a plus (+) or minus (–) sign to show relative standing within the major rating categories.

The following describe characteristics of short-term (original maturity of 365 days or less) bond and commercial paper ratings designations provided by Standard and Poor’s:

A-1 —These are the highest rated obligations. The capacity of the obligor to pay interest and repay principal is strong. The addition of a plus sign (+) would indicate a very strong capacity.

A-2 —These obligations are somewhat susceptible to changing economic conditions. The obligor has a satisfactory capacity to pay interest and repay principal.

A-3 —These obligations are more susceptible to the adverse effects of changing economic conditions, which could lead to a weakened capacity to pay interest and repay principal.

B —These obligations are vulnerable to nonpayment and are significantly speculative, but the obligor currently has the capacity to meet its financial commitments.

C —These obligations are vulnerable to nonpayment, but the obligor must rely on favorable economic conditions to meet its financial commitment.

D —These obligations are in default, and payment of principal and/or interest is likely in arrears.

B-80


 

The following describe characteristics of U.S. municipal short-term (original maturity of 3 years or less) note ratings provided by Standard and Poor’s:

SP-1 —This designation indicates a strong capacity to pay principal and interest. SP-2 —This designation indicates a satisfactory capacity to pay principal and interest. SP-3 —This designation indicates a speculative capacity to pay principal and interest.

Item 29. Persons Controlled by or under Common Control with Registrant

The Registrant does not control and is not under common control with any other person .

Item 30. Indemnification

The Registrant’s organizational documents contain provisions indemnifying Trustees and officers against liability incurred in their official capacities. Article VII, Section 2 of the Amended and Restated Agreement and Declaration of Trust provides that the Registrant may indemnify and hold harmless each and every Trustee and officer from and against any and all claims, demands, costs, losses, expenses, and damages whatsoever arising out of or related to the performance of his or her duties as a Trustee or officer. Article VI of the By-Laws generally provides that the Registrant shall indemnify its Trustees and officers from any liability arising out of their past or present service in that capacity. Among other things, this provision excludes any liability arising by reason of willful misfeasance, bad faith, gross negligence, or the reckless disregard of the duties involved in the conduct of the Trustee’s or officer’s office with the Registrant.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 (the Securities Act) may be permitted for directors, officers, or persons controlling the Registrant pursuant to the foregoing provisions, the Registrant has been informed that in the opinion of the Securities and Exchange Commission, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.
