The deliberations for the beer companies, which belong to SABMiller, are at a preliminary stage, the people said, asking not to be named because the plans aren't yet public. No final decision on the sale has been made and a formal sale process hasn't started, one of the people said. Representatives for SABMiller and AB InBev declined to comment. SABMiller agreed to sell its 58% stake in MillerCoors to partner Molson Coors Brewing Co. in a $12 billion deal earlier this month to win regulators' approval.
