What is an "FMU" Corporation?

I checked game documentation under "F," and found nothing, so here is my question post.

I noticed today, I got an entirely brand new private corp! But it is not run by another player; it is an "FMU" Corporation.

While I am happy to see at least 2 private corporations in my empire, I would like to learn:

(a) what is an FMU Corp? and
(b) are there things I can do to encourage more of them? and
(c) are they as good for my country as player-run corporations.

thanks

If you click on the name of the corp and scroll to the top of the next page, you will see what type of product the corp produces. I'm willing to bet a few shekels that corp produces factory maintenance units.

FMU are excellent corps for your country. They usually pay high country resource fees. They also employ lots of highly paid engineers, who then pay 40% of their income to your country as taxes.

If you get more corps that employ lots of engineers, your country will collect plenty of taxes from citizens. Heck, if I were you, I would only allow engineer-intensive corps.
