2025 TARGET RETIREMENT ACCOUNT 

Following is a summary of information about the 2025 Target Retirement Account. Investors are advised to learn key data about an investment prior to making any investment decision.

Objective

The objective of this account is to seek to provide growth of capital and current income consistent with its current asset allocation. It is invested solely in the Sentry 2025 Target Retirement Portfolio.

Investor Profile

The 2025 Target Retirement Account may be suitable for investors planning to retire in or within a few years of 2025, and seeking a simple way to achieve a broadly diversified holding of stocks and fixed-income securities. Individuals must be willing and able to accept significant fluctuations in unit price and have a relatively long (more than five years) investment horizon.

Investment Strategy

Sentry Target 2025 Retirement Portfolio invests in seven different asset classes by utilizing exchange traded funds (ETFs) and employing an asset allocation strategy designed for investors currently planning to retire in about 2025. The portfolio’s asset allocation will gradually become more conservative and modestly income-oriented every year. By 2025, the portfolio’s asset allocation will be similar to the Target Retirement Income Account.

The portfolio is periodically rebalanced to smooth out the highs and lows of investing in a single, volatile asset class like large cap stocks.

Investment Considerations

The 2025 Target Retirement Account is subject to several stock and bond market risks, any of which could cause an investor to lose money. However, given the current allocation between stocks and the less volatile asset class of bonds, the overall level of risk should be higher than those alternatives that invest the majority of their assets in bonds, but lower than that of alternatives investing entirely in stocks.
