I think in this case the revenue ranges from 1-3 years depending on how long the user signed up for.
I was thinking today if that's all to be realised in the next 12 months, you'd just add it into the revenue earned in FY14, assuming 98% renewal rate. But, it's too good to be true and it'll be spread out over the next few years.
I'd like to see a quarterly cash flow statement, any reason they stopped?
