May 2018

Dear Financial Advisor:

A special meeting of shareholders of the McDonnell Intermediate Municipal Bond Fund (the “Fund”) has been scheduled for Wednesday, June 19, 2019. In November 2018, Natixis Investment Managers, L.P. announced plans to transfer ownership of McDonnell Investment Management, LLC (“McDonnell”) to Loomis, Sayles & Company, L.P. (“Loomis Sayles”) on January 1, 2019, and to transfer or integrate various operations of McDonnell to or into Loomis Sayles on or about June 30, 2019. Both McDonnell and Loomis Sayles are affiliates of Natixis Investment Managers. As part of that process, some personnel of McDonnell will become personnel of Loomis Sayles. Loomis Sayles will assume responsibility for management of the Fund’s portfolio and McDonnell will dissolve. When that transfer occurs, the current sub-advisory agreement with McDonnell will terminate. It is expected that three of the Fund’s four current portfolio managers, supported by the current roster of traders and research analysts, will continue to manage the Fund under the current strategy as employees of Loomis Sayles. In order for the Fund to continue to operate as part of Loomis Sayles, shareholders are being asked to approve a new sub-advisory agreement with Loomis Sayles.

Every vote counts

Every vote is extremely important. Shareholders will be receiving a packet containing a proxy card, proxy statement, and a letter similar to this one soon. Please encourage your clients to vote their shares, whether or not they plan to attend the meeting. Computershare, a professional proxy solicitation firm, has been retained to assist the Fund in obtaining shareholder votes. If we do not receive enough votes to hold the meeting, we will be required to re-solicit shareholders at additional expense to the Fund.

If shareholders vote using the Internet, telephone or in person, they do not need to mail in their proxy card. If they would like to change their vote, they may do so by using their proxy card, Internet, or telephone or by voting in person.

Sincerely,

David L. Giunta

President
