HONG KONG, June 28 (Reuters) - South Korean game developer Krafton Inc said on Monday it will resubmit an application for a $5 billion domestic listing after the financial regulator raised some questions on the application, which, sources said, could delay the listing. “Krafton plans to revise our IPO registration statement in response to the Financial Supervisory Service’s request,” the company told Reuters in a text message. The delay of the initial public offering (IPO), set to be South Korea’s biggest ever, could be for up to a fortnight as a result of the regulatory review, according to two people with direct knowledge of the matter. In its message, Krafton did not comment on the IPO’s delay. The people could not be named as the information was not yet made public.
