Perhaps this would inform the discussion better, but how do you define "profitability" if not by accounting profit? There has to be a strict measure in order to make sense of things. As. I said before, the convention is to use profitability = accounting profit.

I judge by your statements of RedHat's expenses/revenue/profitability that you're defining it as operating profit? That's not a great measure to look at things: certain sectors can expense things and make a mess of it - like depreciation & R&D.

That's also a measure of the core operating portion of the business alone, it. doesn't include non-core portions, nor spending on investments/divestitures (although the latter should show in pro formas or future reports. Also to be fair that would never be counted in a profit definition, but judging from what you find important, I suspect you would prefer to include it? ).
