The Charities Commission website in the UK by law shows the accounts of all UK registered charites. This link is to the Watch Tower Bible and Tract Society of Great Britain.
The accounts show the following note:
13. EXCEPTIONAL ITEMS
During the year, the decision was made to write off all loans to congregations for the purpose of building places of worship, at a cost of £9,245,076.
They also show that the income for 2013 was £17,073,074
The income for 2014 was £35,525,358
So, the grab back netted £18.5m
From that they wrote off £9.2m
Profit on the deal £9.2m
Please note: I am not an accountant and these figures are grossly simplified.
IBSA is the other charity associated . http://apps.charitycommission.gov.uk/Showcharity/RegisterOfCharities/CharityWithPartB.aspx?RegisteredCharityNumber=216647&SubsidiaryNumber=0
It is difficult to extract the overall financial position without accounting analytical skills. If there is someone on this forum with appropriate ability there is some interesting information in there to extract.
I have not seen this referred to before, if it has, I apologise.
