Research in Motion Inc.'s co-chief executive officers, plus co-founder Douglas Fregin, made Forbes magazine's billionaire's list.
The American magazine this week published a list of the world's nearly thousand billionaires, with Microsoft Corp. founder Bill Gates taking second place.
Using pricing information from the Internet auto guide, Network World Canada calculated Balsillie can afford 6,000 Lamborghini 2010 Murcielago LP640 Roadsters, though it’s not clear whether they would all fit in his driveway.
Balsillie was tied in 421st place with other tycoons such as Wallace McCain, vice-chairman of his family's frozen food business and father of Maple Leaf foods CEO Michael McCain.
Fregin, who co-founded RIM and retired in 2007, has $1 billion.
Other notable technology names on the list include Google Inc. co-founders Sergey Brin and Larry Page, who each have $17.5 billion.
Due to high apartment rent rates in the city of Toronto and other factors, no one from Network World Canada’s editorial staff made Forbes' list this year.
