I was involved in a lawsuit regarding Salem Corporation when Salem was controlled by an evil man named Victor Posner. Posner was looting the company like he looted all of the public companies he controlled. Three of us shareholders filed a derivative suit against Salem and Posner. We managed to do it on a contingent fee basis with a law firm.
Nevertheless, it lasted four years and we never really got any results. Eventually the court put demands on both sides and the case was settled. Salem had been paying the legal fees to fight us. The settlement required that Salem pay a large legal fee to our lawyer and small settlement amounts to the three of us. So the real loser was the company that we owned stock in.
Eventually, the SEC ruled that Posner and his son could no longer be officers or directors in any public company as a result of legal action regarding DWG Corporation. Later both Salem and DWG were sold to other buyers.
My point in writing this message is that it will not be cheap or quick to do anything legally against NWLI. NWLI has been managed much better than Salem and DWG and the Moodys do not have the unsavory reputation that Victor Posner had. So, you and any other parties that may be considering legal action may do what you want, but I can assure you that it won't be like waving a magic wand and making the problem go away.
