Saudi oil giant Aramco announces world's largest IPO.

Saudi Arabian state oil giant Saudi Aramco on Thursday priced its initial public offering (IPO) at the high end of the targeted range, a level that will allow the company to raise a record total of at least $25.6 billion.

The company plans to sell 3 billion shares, or 1.5 per cent of its total shares, at a price of 32 Saudi riyals ($8.53) per share.

The company will offer 33.3 percent of the available shares (0.5 percent of Aramco's total shares) to retail investors, while the remaining 66.7 percent have been allocated for institutional investors.
