Maybe they have to capture all of the past history to capture any loss carry forward for tax benefits. I am not a tax expert, so don't know how long tax carry forwards work. Old GRNO never had any meaningful revenue, but did have expenses.
Well every set of financials I've ever read were a quarterly affair and this company was no more than a shell as I understand it with no revenue what so ever until just recently. If I'm correct then how hard is it to enter a bunch of zeros?
