Put yourself in the Org's position - distasteful as that is - and come up with a solution to solve the problems of not only recovering their Stock Market losses, but also, ensuring an increase in their dwindling revenue stream.
The major problem is, donations are voluntary (with no future guarantees) whereas pledges are compulsory - in the heart and mind of the giver!
However, far too many will probably forget/refuse to keep up their monthly tax - with no way of knowing who is 'paying the man', and who is not.
Master stroke - Make Plan A 100% certainty to fail in the first year, based on the 'anonymity' of the setup. That then justifies Plan B - (in the obedient sheep's eyes!) the G.B.'s future letter requiring that all who have pledged donations, to arrange the payment of their pledge via their bank account every month. Following this loving provision and direction will save the Friend's from forgetting to 'render their dues' as promised.
Now the Org can clearly pinpoint to the local Elders which sheep aren't parting with their fleece - and guilt them into doing so!
