That amount is simply representative of a paper transaction to "forgive" Kingdom Hall loans. It is a side step to fall in line with the allowable "donation" system of income. Loans are not considered an allowable form of revenue for charities.
So the fact that the forgave the loans because they were technically illegal to make being that they were a charity. If I remember right they also charged interest on those loans in the past. So I think this alone warrants a audit plus some stiff penalties I would assume.
I would be so happy if the IRS did an audit of the WT corporation I'm sure they would find a lot of illegal activity that benefits some third parties when they do.
