Official bookbuilding is due to start today for the IPO of Naibu, the Chinese sportswear manufacturer. According to Peter Shea, chairman and CEO of Daniel Stewart & Co, the bookrunner on the deal in London, up to 70 institutions were visited in marketing the deal and only one or two are said to have declined. The deal could raise up to £50 million ($79 million) and kick-start a fresh round of Chinese listings on London’s second market.
