The WT has had a high powered, aggressive CPA at the head of financial matters since the early 80's and full time since the mid nineties. He is now the Secretary/Treasurer. His job is to keep the corporation going. IMHO, the figures they let the publishers see mean nothing, I mean as far as the viability of the corporation.
I don't think he could have anticipated the expense of the legal problems, but under his guidance they will trim, invest/divest...do whatever to keep the corporation afloat. All their moves, though surprising, are smart financially, which is all that matters to a corporation. They have millions from the real estate sell off. The printing might have brought in millions but it was an expensive operation, and not efficient in today's world.
If they can keep countries self sufficent for the most part, as in the KH charge offsetting the stipends for the full time workers, and the congregations support their expenses, cost to HQ could be quite low in the big picture. They take full advantage of government provisions for non-profits/charities in countries. It is all a money game and they know what they are doing.
I hope the recent spotlight on shunning, pedophilia, etc. will keep the legal team busy with settlements.
