Ann: Q2 FY18 Market Update - Update to Cash Revenue Guidance, page-216

Perhaps a reason for the downturn in the share price is the success of growth in the US! A fact that I have not seen discussed is that the strategy for the US must cause negative revenue as expenses are born upfront but the 12 month subscription method must mean that these are not covered until around at least 5 to 7 months of income recover them.
This would see that the accumulated cash from Oz is needed to fund this US strategy, causing uncertainty as to the attainment of eventual profit.
Certainly the high level of renewals provides profitable revenue but these come from low numbers when compared to the actual growth of the business.
Deferred revenue is another matter affecting profit.
This is a very different business to any other and cashflow management is a critical element requiring information from the Company (perhaps) when the half yearly report surfaces around February.
They have a relationship with a business that focuses on this issue so it may be reasonable to expect that they have this well in hand.
However, until the numbers (audited) come to hand some are likely to wonder.
Personally, I think BIG is unlike any other & is a winner but time will tell!
