Tier 1: Target Date Funds
Instant investment diversification
RPB’s Tier 1 target date funds—the T. Rowe Price Retirement Blend Trusts—are built for participants who want a simple way to invest. Each target date fund is a fully diversified, pre-assembled portfolio that’s targeted to a specific retirement date. Participants typically invest in a fund with a target date closest to the year they turn 65.
How target date funds work
The difference between target funds and other diversified funds is that the allocation of stocks and bonds isn’t fixed: It changes over time to intentionally reduce your exposure to investment risk as you get older using an investment approach called a glide path.
Why is that important? When you’re younger and have more time to ride out the ups and downs of the market, you usually want to be aggressive. That means relying more heavily on stocks. As you get closer to retirement—and closer to needing your money—you typically want to preserve what you’ve saved by shifting into less risky investments, like bonds. Target date funds make these adjustments to your investment mix gradually and automatically—so you don’t have to.

Selecting a fund from the new Tier 1 lineup
To invest in Tier 1, simply select the one fund that aligns to your birth year, and you’re done! You’ll have a professionally managed, diversified portfolio for your savings in the RPB retirement plan.
Depending on your risk tolerance, time horizon, and financial situation, you may consider a fund with an earlier (more conservative) or later (more aggressive) target date than the one aligned with your birth year.
