At a meeting held on April 19, 2018, the Board of Trustees of PowerShares Exchange-Traded Self-Indexed Fund Trust (the “Trust”) approved a reduction in the annual unitary management fee for each Corporate Bond Fund to 0.10% of such Corporate Bond Fund’s average daily net assets, effective April 20, 2018. Accordingly, the Prospectus and Statement of Additional Information are revised as follows:

• The following replaces the first paragraph and table included under the section titled “Fund Fees and Expenses” in each Corporate Bond Fund’s respective Summary Prospectus and Prospectus:

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors may pay brokerage commissions on their purchases and sales of Shares, which are not reflected in the table or the example below.

Annual Fund Operating Expenses
(expenses that you pay each year as a percentage of the value of your investment)
Management Fees(1)	0.10	%
Other Expenses(2)	0.00	%
Total Annual Fund Operating Expenses(1)	0.10	%

(1) Effective April 20, 2018, Invesco PowerShares Capital Management LLC (the “Adviser”) has contractually reduced the Fund’s unitary management fee from 0.24% to 0.10%. Management Fees and Total Annual Fund Operating Expenses in the table above have been restated to reflect current fees.

(2) “Other Expenses” are based on estimated amounts for the current fiscal year.

• The following replaces the section titled “Example” in the Summary Prospectus and of the Prospectus for each Corporate Bond Fund:

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds.

This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. This example does not include the brokerage commissions that investors may pay to buy and sell Shares. Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

1 Year		3 Years		5 Years		10 Years
$	10	$	32	$	57	$	128

• On page 119, the information in the table for the Corporate Bond Funds under the section titled “Management of the Funds—Advisory Fees” in the Prospectus is deleted and replaced with the following:
