Bangladesh’s largest ever initial public offering by mobile phone provider Grameenphone was oversubscribed by several times, notes AFP, as the window for local subscriptions closed. “The response from retail investors has been overwhelming,” Silmat Chisti, head of the issue manager company, Citigroup Global Markets, said. Grameenphone plans to raise US$70.4 million through the IPO sale of 69.44 million shares.
