THANK YOU FOR CASTING YOUR VOTE

Hi [Insert Client’s Name],

We have identified that your office has received a large number of Proxy Ballots for the current SEI Fund Proxy.  You have received them by either email or paper or a combination of both.  SEI would like to help you facilitate your response by offering a BULK Voting option. 

If you would like to participate in the BULK Vote, please reply to this email and attach your completed Bulk Voting Form. Also, please remember to include the spreadsheet with your response.

If you would prefer to submit your bulk vote electronically, please follow this link (insert link)

Your vote is important.  We are not advocating that you vote the shares over which you have voting authority for or against any particular proposal.  Your prompt response will enable the Funds to hold the shareholder meeting on time and save the expense of additional solicitation costs if not enough shareholders vote.

As a reminder, the Proxy contains three proposals outlined below:

Proposal 1: To elect a slate of nominees, each of the current Trustees and new Trustees to the Board of Trustees.

Proposal 2: To amend the Agreement and Declaration of Trust for each of SIMT and SIT to reduce the shareholder quorum requirement from a majority to one-third (33-1/3%).

Proposal 3: To reclassify the diversification status of the SIMT Large Cap Growth Fund from diversified to non-diversified and eliminate a related fundamental diversification policy.

If the necessary proxy cards are not returned in a timely manner, reminder mailings will be placed to shareholders requesting that they complete and return the cards.

Thanks for your time.  I look forward to your response.

Thanks,

[Insert Service Person Name]
