Aren’t Foundations supposed to be none profit. Sounds like they feel that they are above the laws that little people must abide by.
Foundations and non-profits invest their cash somewhere. They can purchase equities just like you and me. As you know, the return on equities sure has beaten bonds the last coup.e of years.
The law says they cannot own more than 20% of the shares in a company. That is a LOT MORE restrictive than the law for you and me.
Would you rather entirely forbid them from owning any stocks?
Non-profit does not mean they cannot end up with more money. Non profits do not have a goal to make more, but if they do if they still appear to be doing their purpose its incidental that they end up with more money.
