Cessna's Corporate Diversification

Since it is rolled up into Textron's financial report, gathering data for Cessna's performance as a company in and of itself has proven next to impossible.  Looking at Textron's financial report, though, the aviation division is significantly diversified.  Apart from Cessna (which in and of itself is made up of multiple divisions), Textron Aviation also contains Beechcraft and Hawker, new acquisitions to the corporation.  One thing I've learned is that diversification can have many levels set up and get quite confusing if one is interested in gathering information on one business unit in the whole.
