This kind of thing is likely deliberate. If an underperforming division 
were reported on its own, there would be pressure from shareholders, 
beancounters etc to do something like lay off staff or otherwise cut 
resources, spin it off ... in short, disembowel it in some way.

So my guess is, what’s left of the legacy mainframe business is very 
likely a minuscule, even negative contributor to overall profit.
