Its possible they did this, but it is small, small potatoes to GE’s total revenue. Usually you are talking like .35% vs .70% of revenue and its usually passive vs actively managed funds. The debate rages on. Lawyers are the only ones that win in those lawsuits, though.
It sure as hell made a difference to their employees who got stiffed.
Note that GE's stock has FALLEN significantly over the last 15 years; note also the Jeff Immelt, for all his offshoring to CHINA the ENTIRETY of the GE Medical Imaging "to save costs".
Now GE is talking of cutting their dividend: and they've been on the S&P 500 since 1896 IIRC. And all his "Green" posturing...
Well, Immelt not only flew a private jet everywhere; he had an EMPTY identical jet fly behind it (and go to another area of the airport to prevent gossip) just in case something went wrong with the first jet.
Oh, and to top it off: the jets he flew didn't even use GE engines, but Rolls-Royce engines.
Forced confiscation of his entire estate,and selling himself, his heirs, and assigns, into slavery to ISIS, would be too good for him.
