LARGE CAP INDEX ACCOUNT

Following is a summary of information about the Sentry Large Cap Index Account. Investors are advised to learn key data about an investment prior to making any investment decision.

Objective

The objective of the Large Cap Index Account is to seek to replicate the aggregate price and yield performance, before expenses, of the S&P 500 Index. The account invests solely in the Vanguard® Index 500 Fund.

Investor Profile

The Large Cap Index Account may be suitable for investors with a long-term investment horizon who are seeking long-term growth of capital and income from dividends by participating in the large capitalization sector of the U.S. stock market. Individuals must be willing and able to accept considerable changes in unit price both in the short and long term.

Investment Strategy

The Vanguard Index 500 Fund invests in all 500 stocks listed in the S&P 500 index in approximately the same proportion as they are represented in the index. The correlation between the performance of the fund and that of the index is expected to be 0.95 or higher. The unmanaged Standard & Poor’s 500 Composite Stock Price Index is a widely recognized benchmark of the U.S. stock market performance. The fund remains fully invested at all times and does not speculate on the direction of the index. To assure a fully invested position given daily cash flows into and out of the fund, the advisor normally holds up to 5 percent of the fund’s net assets in S&P 500 futures contracts.

Investment Considerations

The Large Cap Index Account takes a passive/index, unmanaged approach to investing in 500 of the largest U.S. companies. This Account is appropriately used by investors seeking an exposure to 500 of the largest U.S. companies for part or all of their retirement portfolio.
