HONG KONG -- AB InBev has priced the initial public offering of its Asian unit at the bottom end of the marketed range, putting it on course to raise about $5 billion. Shares in Asia's largest IPO so far this year by Budweiser Brewing Company APAC were priced at HK$27 each and the company has partially exercised an option to increase the size of the deal "to cover market demand," it said in a statement. The company began marketing the shares last week with an indicative range of HK$27 to HK$30.
