I am responding to you from the perspective of a founder/CEO/entrepreneur, non-practicing lawyer and one who has observed issues of others derived from this topic. I am not offering an answer.
In my view there is not a simple answer. It is an issue that deserves the best opinions and drafting by tax and estate counsel and views by a crown-jewel valuation expert who has testified many times in civil and tax litigation on similar issues. You might want to check Comcast's 10K to see their different voting rights on the same classes of stock, unless they have corrected the issues. A lot of the multiple answers have to do with how voting rights impact the allocation of value to different shareholders in a capital event or in the instance a large block of super-voting shares end up in an estate. I have never used a C Corporation and always used an Delaware LLC where it is easy to allocate value and voting rights among different classes of shares and owners. I am not current on public LLC's. My guess is that the most established state law on this issue is in Delaware. Bottom line, from experience I know that this is a complicated tax issue that is worthy of paying the best legal and valuation experts before you do anything rather than waiting until you lose to find out the answers.With all due respect, I would only lightly listen to investment bankers and finalize everything with counsel who has "done this before." It's critical that the drafter of the agreement has spent a lot of time litigating the issue in court....not an issue for a lawyer to 'learn on job' in his/her first court case.
I am not sure if this pertains to this issue, but I am almost always in favor of formally agreeing that potentially complicated, costly and political disputes or claims be resolved by binding arbitration, rather than litigation, before the American Arbitration Association (www.adr.org) or JAMS (www.jamsadr.com/) (the largest private alternative dispute resolution (ADR) provider in the world specializing in mediating and arbitrating complex, multi-party, business/commercial cases - those in which the choice of neutral is crucial). This requires exquisite attention to detail in pre-setting the rules in the founding agreements. Otherwise you may be dealing with a lot of confused judges, lawyers and jurors; and the party with the most money and best story usually financially squeezes the smaller party and wins disputes.
Good luck, D
