The internet major noted that both companies would mutually agree on a retention plan which would be taken care of by Microsoft, for the transferred employees.
Further, upon mutual agreement, Microsoft would use another 150 employees of Yahoo! to assist with providing the transition services, the filing said.
Microsoft and Yahoo! last month announced a partnership which will bring the companies together in the search arena and sales activities related to search advertising.
Both companies would enter into a 10-year agreement for the proposed partnership and Yahoo! would be paid 88 per cent of the search advertising revenues generated in the first five years of the alliance.
