⁽¹⁾Management Fees have been restated to reflect contractual changes to the Fund's Investment Advisory Agreement effective June 1, 2018.

⁽²⁾Total Annual Fund Operating Expenses have been restated to reflect contractual changes in the management fees. These fees will differ from the ratio of expenses to average net assets that is included in the Fund's annual report for the fiscal year ended September 30, 2017.

⁽³⁾Touchstone Advisors, Inc. (the "Advisor" or "Touchstone Advisors") and Touchstone Funds Group Trust (the “Trust”) have entered into a contractual expense limitation agreement whereby Touchstone Advisors will waive a portion of its fees or reimburse certain Fund expenses (excluding dividend and interest expenses relating to short sales; interest; taxes; brokerage commissions and other transaction costs; portfolio transaction and investment related expenses, including expenses associated with the Fund's liquidity providers; other expenditures which are capitalized in accordance with U.S. generally accepted accounting principles; the cost of “Acquired Fund Fees and Expenses,” if any; and other extraordinary expenses not incurred in the ordinary course of business) in order to limit annual Fund operating expenses to 1.22%, 1.97%, 0.97%, and 0.84% of average daily net assets for Classes A, C, Y and Institutional Class shares, respectively. This contractual expense limitation is effective through January 29, 2019, but can be terminated by a vote of the Board of Trustees of the Trust (the “Board”) if it deems the termination to be beneficial to the Fund’s shareholders. The terms of the contractual expense limitation agreement provide that Touchstone Advisors is entitled to recoup, subject to approval by the Board, such amounts waived or reimbursed for a period of up to three years from the date on which Touchstone Advisors reduced its compensation or assumed expenses for the Fund. The Fund will make repayments to the Advisor only if such repayment does not cause the annual Fund operating expenses (after the repayment is taken into account) to exceed both (1) the expense cap in place when such amounts were waived and (2) the Fund's current expense limitation.

⁽⁴⁾Total Annual Fund Operating Expenses after fee waiver and/or expense reimbursement will differ from the ratio of net expenses to average net assets that is shown the annual report for the fiscal year ended September 30, 2017 due to a contractual change in the Fund's expense limitation agreement that took effect June 1, 2018.

Example. This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then, except as indicated, redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year, that the Fund’s operating expenses remain the same and that all fee waivers or expense limits for the Fund will expire after one year. Although your actual costs may be higher or lower, based on these assumptions your costs would be:



	Assuming Redemption at End of Period								Assuming No Redemption
	Class A		Class C		Class Y		Institutional Class			Class C
1 Year	$	618	$	300	$	99	$	86		$	200
3 Years	$	910	$	685	$	328	$	296		$	685
5 Years	$	1,224	$	1,196	$	576	$	524		$	1,196
10 Years	$	2,110	$	2,601	$	1,286	$	1,178		$	2,601
