Warning: This thread has a lot of material AND there are many posts. Each post will explain how the numbers came about.
PLEASE READ CAREFULLY. This is a fairly in-depth analysis. All assumed figures will be indicated with a (*). All other numbers are taken directly from MSFT publicly reported financial statements.
I have used FY ending June 2006 as a reference to baseline some figures. I will explain when needed.
Prior to FY End Jun 2007, the Game Division was by itself (with PC Games), and I think with consumer hardware and software. There was also a separate Windows Mobile Division.
There was no Zune product in FY end Jun 2006.
Difference between Sony and MSFT analysis:
1. Sony analysis used NET PROFIT assumptions
MSFT analysis uses GROSS MARGIN assumptions
Because MSFT mentions specific line item expenses (eg. Marketing, R&D), we can infer and calculate some numbers based on those statements.
2. Sony analysis didn’t include Revenue
MSFT analysis uses Revenue – hence it is inherently more difficult to match BOTH revenue and gross margin and net income.
In the MSFT analysis, I have introduced the “Variance” to account for any other “unaccounted” that can not fit both revenue and gross margin figures.
If we used Revenue for the Sony analysis, there would have been the “Variance” line item for both revenue and net profit as well.
