That is exactly what happened. The increase in A/S was never anything more than contingency to fulfill the ongoing Business Plan. When enough A/R and payment from orders came in, the additional A/S lying in wait was not needed, so the announcement of the intended reduction.
Another thing we need to remember, the reason for the sharp, and continual, decrease in A/R is due to online and phone orders. I ordered my supply over the phone and my Credit Card was debited within a matter of a couple of days. Normally, this will never even hit A/R, as it went straight from order status to Cash.
I believe this is a primary reason self-funding is in place and consequently A/S able to be reduced.
