We don't know how much money they possess. It is possible that ordinary Witnesses take such umbrage at the Conti case that their contributions have increased more than any possible ultimate damage award. Don't count your Conti money before the appellate courts decide in your favor. Their liability may be negative.
No one here has standing to find out what their financial status is now. The general public is much more fascinated with the holdings of the Roman Catholic Church. Several parts of the Catholic puzzle are transparent. Yet the most important pieces remain secret, esp. the holdings of the Vatican Bank. I once worked on a local prosecution that involved the Vatican Bank. Witnesses were being assasinated on special London bridges. Medieval secret societies were used. I cursed the day I was assigned to the case. Their art work is absolutely priceless.
The Witnesses have always been secretive. I don't know if any religion publishes this sensitive information about itself. We should not expect the WT to reveal more than other religions. I wonder how many people even have knowledge of the correct sum.
