Portfolio Profile

As of December 31, 2014

30-Day SEC Yield. A portfolio’s 30-day SEC yield is derived using a formula specified by the U.S. Securities and Exchange Commission. Under the formula,

data related to the portfolio’s security holdings in the previous 30 days are used to calculate the portfolio’s hypothetical net income for that period, which is

then annualized and divided by the portfolio’s estimated average net assets over the calculation period. For the purposes of this calculation, a security’s

income is based on its current market yield to maturity (for bonds), its actual income (for asset-backed securities), or its projected dividend yield (for stocks).

Because the SEC yield represents hypothetical annualized income, it will differ—at times significantly—from the portfolio’s actual experience. As a result,

the portfolio’s income distributions may be higher or lower than implied by the SEC yield.

Acquired Fund Fees and Expenses. Portfolios that invest in other Vanguard funds incur no direct expenses, but they do bear proportionate shares of the

operating, administrative, and advisory expenses of the underlying funds, and they must pay any fees charged by those funds. The figure for acquired fund

fees and expenses represents a weighted average of these underlying costs. Acquired is a term that the Securities and Exchange Commission applies to any

mutual fund whose shares are owned by another fund.

Beta. A measure of the magnitude of a portfolio’s past share-price fluctuations in relation to the ups and downs of a given market index. The index is assigned

a beta of 1.00. Compared with a given index, a portfolio with a beta of 1.20 typically would have seen its share price rise or fall by 12% when the index rose

or fell by 10%. For this report, beta is based on returns over the past 36 months for both the portfolio and the index.

R-Squared. A measure of how much of a portfolio’s past returns can be explained by the returns from the market in general, as measured by a given index.

If a portfolio’s total returns were precisely synchronized with an index’s returns, its R-squared would be 1.00. If the portfolio’s returns bore no relationship to

the index’s returns, its R-squared would be 0. For this report, R-squared is based on returns over the past 36 months for both the portfolio and the index.

All of the returns in this report represent past performance, which is not a guarantee of future

results that may be achieved by the portfolio. (Current performance may be lower or higher than

the performance data cited. For performance data current to the most recent month-end, visit our

website at vanguard.com/performance.) Note, too, that both investment returns and principal

value can fluctuate widely, so an investor’s shares, when sold, could be worth more or less than

their original cost. The returns shown do not reflect taxes that a shareholder would pay on portfolio

distributions or on the sale of portfolio shares. Nor do the returns reflect fees and expenses associated

with the annuity or life insurance program through which a shareholder invests. If these fees and

expenses were included, the portfolio’s returns would be lower.
