MFS Investment Grade Municipal Trust

MFS Investment Grade Municipal Trust is a company, not a closed-end fund. We still track it - notices about it are below - but most of this site is about funds.

Is anyone targeting this fund?

Yes - one large investor holds a stake, but it has not asked for changes.

What this means for you

One or more large investors own more than 5% of this company but have told the regulator they are not seeking changes. That is common for banks, brokers and index funds that hold shares for their clients.

Nothing is required of you. If an investor changes its mind, it must file a new notice within days, and it will show up here.
