The other option is to “kick the can down the road” and accept a tax free exchange of stock in the acquiring company...this works if it’s a great company..you get instant liquidity (and you take the risk of the stock going down and the happy risk of appreciation)
As for me I just take the cash and pay the tax and be a happy camper...$10 or more would be a nice price for me....maybe in 2019 or 2020?
Sounds like Zenith could be a world class “ultra blockbuster” down the road.
Just sayin’ (all IMHO)
