Each reorganization will consolidate the assets of the Funds and place shareholders of each Institutional Target Retirement Fund in a larger combined fund with an identical investment objective, investment strategies, and investment risks and a lower expense ratio. Following each reorganization, it is expected that the expense ratio for each Target Retirement Fund will be reduced to 0.08%. The reorganization does not require shareholder approval and is expected to close on or about February 11, 2022. Prior to the closing, shareholders of each Institutional Target Retirement Fund will be issued a

combined Information Statement/Prospectus, which will describe the reorganization, provide a description of each Target Retirement Fund, and include a comparison of the Funds.
Under the Agreement and after the closing, shareholders of each Institutional Target Retirement Fund will receive Investor Shares of the corresponding Target Retirement Fund in exchange for their Institutional Shares of the Institutional Target Retirement Fund, and the Institutional Target Retirement Funds will cease operations.
We anticipate that the reorganization will qualify as a tax-free reorganization under the Internal Revenue Code of 1986, as amended.
