Corney those figures you present are very interesting. Can I ask are they publicly available? I would interested in both sets of figures for all the years from 2009, or earlier, if availabe.
They look credible to me and I think we can draw some conclusions.
There seemed to be a significant drop in the assets of the Pennsylvania corporation in 2015. It was the same year that Lett issued the call for more donations.
Then the combined assets of both corporations increased from 2014 to 2017 by $315 million, or 19%.
This was the period during which Lett begged for more donations, congregations were instructed to send excess funds to HQs, and KHs began to be sold and the funds sent to the society.
In other words confiscating local KH funds resulted in a $300 million boost in Watchtower assets. That would mean Watchtower gained around $20,000 from each congregation on average. That is a trick you can only pull once, as is selling KHs and assembly halls, because when the local bank balances and KHs are gone they are gone.
