The answer is tantalizingly close and yet just out of reach. An interested reader can find some of the relevant information here, in a Deutsche Bank prospectus for potential investors in Bain Capital. On pages 16 and 17, the prospectus lists all the investments made by Bain Capital from 1984-1998, roughly the time that Mitt Romney ran the company. For example, their 1984 investment of $2 million in Key Airlines led to an annual return of 52.9%. It does not tell you how much money investors made because you would have to subtract off Bain’s fees which this Table does not have (other parts of the prospectus may help you to do that). The thing that is impossible to work out is the employment impact of Bain’s investments. The prospectus does not say anything about that issue. But the names of the companies are listed in the left hand column. So, it might be possible to work out what happened to these companies via a web search and come up with some answers.
If someone had the time and the ability to do that, it would be very interesting I think. I’d certainly be interested in the answer.
