The T. Rowe Price Retirement 2010 Fund strategically invests its assets across a diverse array of other T. Rowe Price mutual funds, encompassing both equity and fixed-income options that span various asset classes and market sectors. The composition of its underlying T. Rowe Price fund holdings is periodically rebalanced, progressively altering its asset allocation as it draws closer to its specified retirement horizon. This fund's investment approach is tailored to the target retirement year of 2010, as reflected in its title, and operates on the presumption of an investor retiring at age 65.
