.[17] Bill Gates reportedly asked Paul Allen to give him some of his share to compensate for the higher amount of work being performed by Gates.[18] Allen thought this was warranted, however when the time came[when?] for the adjustment to occur, Gates decided not to proceed.[19] Instead, Gates tried to buy Allen out at a low price, however Allen refused and left the company with his share intact. This proved critical to Allen becoming a billionaire after Microsoft went public.[20]
