Bank of China, the mainland's second-largest lender, will delay its US$8 billion to US$10 billion planned IPO until as late as June after pressure from Beijing to offer shares in both the mainland and Hong Kong, the Standard of Hong Kong reported, citing sources familiar with the deal. Though the bank succeeded in heading off a simultaneous dual listing by promising to sell A-shares in Shanghai some time in the future, the intervention has thrown the listing off schedule. The H-share sale, expected to be one of the largest this year, was scheduled for the first quarter.
