The rest is probably NRE - no recurring engineering - for hardware / fab costs etc of not doing that participating in that business anymore

an average TI employee costs $100k - $150k / year in salaries only. i guess if you sum up administrative costs/management/travels/equipments/licences and stuff i guess you don't go much up than this. let's say $150k - 200k / year. where are the remaining 100k 

is this right ?

200,000,000 / 650 = 307,692 ???
must have been pretty cushy jobs
