hi sue,
you mentioned funds put 50 million into their investments, and 5 million isnt much for them to put into a company.
If you look at the webpage http://www.trustnet.com/ut/funds/?fund=5978
They have gdn as ranked 5th out of their 10 investments that they hold. So the 5 million dollars they invested into gdn is a large amount of money for that fund to invest into a company.
