LOL, that's the point, depreciation and other non-cash items DON'T affect cash flow.
Positive cash flow means they ARE depositing money in the bank. $15 in there last time they reported.
That's why cash flow is more important than earnings. If you're generating cash, then having a loss based on things like depreciation is not so bad. It saves you a bunch of taxes for starters.
Of course if you have large losses, negative cash flow and no revenues, it's terrible. Luckily, Xata has none of those!
