Fund Description: Vanguard Mega Cap 300 Growth Index ETF is an exchange-traded index fund or Index ETF which is a separate investment portfolio of the Vanguard World Fund, an investment management company. INVESTMENT OBJECTIVE: Vanguard Mega Cap 300 Growth Index ETF seeks to track the performance of CRSP U.S. Mega Cap Growth Index, formerly MSCI US Large-Cap Growth Index. INDEX DESCRIPTION: The CRSP U.S. Mega Cap Growth Index, formerly MSCI US Large-Cap Growth Index is a free-float adjusted, market-capitalization-weighted index designed to measure equity market performance of large-capitalization growth stocks. FUND STRATEGY: The Fund employs a passive management or indexing investment approach designed to track the performance of the Index. The Fund attempts to replicate the target 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. The Fund invests mainly in large-capitalization stocks of U.S. companies considered to have above-average earnings growth potential and reasonable stock prices in comparison with expected earnings. These stocks typically have low dividend yields and above-average prices in relation to such measures as earnings and book value. FUND MANAGEMENT: The Vanguard Group, Inc. serves as advisor to the Funds through its Quantitative Equity Group.
