A majority owners of a company did some actions that the Financial and Capital Market Commission found sketchy. They ended up with an agreement: owners had to make a good offer (more than +50% compared to the price at the moment) to buy all the shares they didn't yet own.
Initially they had around 50% shares, after the mandatory redemption they had almost 93%.
Would most index funds sell their shares to this offer? Or they ignore any events and their shares would be among the 7% that didn't get sold?
