One of the UK’s fastest-growing financial firms has decided to list in the US, filing a 71-page prospectus and lifting the lid on where it makes money, on-going legal issues, and the cost of competition.

Financial data firm Markit has revealed plans for a US initial public offering in which its employee and bank shareholders are expected to receive up to $750 million. The London-based company, which had previously filed confidentially with the Securities and Exchange Commission, made public its IPO filing on Monday.
