The T. Rowe Price Retirement Funds-I Class share the portfolio of an existing fund (the original share class of the fund is referred to as the "investor class"). The total return figures for I Class shares have been calculated using the performance data of the Investor Class up to the inception date of the I Class, as shown in the table above, and the actual performance results of the I Class since that date. Because the I Classes are expected to have lower expenses than the Investor Classes, the I Class performance, had it existed over the periods shown, would have been higher.Investor Class Inception Dates:Retirement 2005, 2015, 2025, 2035 Funds - 02/27/2004; Retirement 2010, 2020, 2030, 2040 Funds and Retirement Balanced Fund - 09/30/2002; Retirement 2045 Fund - 05/31/2005; Retirement 2050, 2055 Funds - 12/29/2006; Retirement 2060 Fund - 06/23/2014; Retirement 2065 -10/13/2020.
