BALANCED GROWTH ACCOUNT

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

Objective

The objective of the Balanced Growth Account is to seek income and long-term growth of capital and income without undue risk of capital. It is invested solely in the Vanguard® Wellington™ Fund.

Investor Profile

The Balanced Growth Account may be suitable for investors with a long-term investment horizon who are seeking long-term growth of both capital and income. Individuals must be willing and able to accept meaningful changes in unit price both in the short and long term.

Investment Strategy

The Vanguard Wellington Fund usually invests from 60 to 70 percent of its total assets in common stocks with the balance held in high-quality bonds and cash. Common stocks are held for potential growth of capital and income, while bonds are held for relative stability of income and principal. Up to 10 percent of its assets may be invested in foreign securities.

Investment Considerations

The principal value of the Balanced Growth Account is subject to fluctuation. This Account has a low turn-over rate and invests in both dividend-paying common stocks and bonds. These factors tend to lessen the risk usually associated with equity investing. Its bond portfolio is high grade and long term, which provides attractive yields but makes it sensitive to changes in interest rates. The Balanced Growth Account may be appropriate as a stand-alone investment or may be used with other accounts to increase or decrease risk and potential return.
