Supplement dated February 5, 2019

to the Prospectus dated October 28, 2018, as supplemented December 31, 2018

This supplement provides new and additional information beyond that contained in the Prospectus and should be read in conjunction with the Prospectus.

The following is hereby added to the front cover page of the Prospectus:

Beginning on February 22, 2021, as permitted by regulations adopted by the Securities and Exchange Commission, paper copies of a Fund’s shareholder reports will no longer be sent by mail, unless you specifically request paper copies of the reports from your Edward Jones financial advisor or from the Fund. Instead, the reports will be made available on a website, and you will be notified by mail each time a report is posted and provided with a website link to access the report.

If you already elected to receive shareholder reports electronically, you will not be affected by this change and you need not take any action. Edward Jones clients investing in a Fund through Edward Jones Advisory Solutions^® may elect to receive shareholder reports and other communications from the Fund electronically by contacting their Edward Jones financial advisor. If you are one of the few direct Fund investors, you may elect to receive shareholder reports and other communications from a Fund electronically by sending an email request to bridgebuilder30e3@edwardjones.com.

You may elect to receive all future reports in paper free of charge. If you are an Edward Jones client investing in a Fund through Edward Jones Advisory Solutions^®, you should contact your Edward Jones financial advisor to request that you continue to receive paper copies of your shareholder reports, and your election to receive reports in paper will apply to all funds held within your Edward Jones account, including the Bridge Builder Mutual Funds. If you are one of the few direct Fund investors, you can inform a Fund that you wish to continue receiving paper copies of your shareholder reports by sending an email request to bridgebuilder30e3@edwardjones.com, and your election to receive reports in paper will apply only to all of the Bridge Builder Mutual Funds.
