A decision on a the fate of three insurance affiliates of bankrupt Metropolitan Mortgage & Securities Co. might be weeks away, according to the Washington state Office of the Insurance Commissioner. Though several bids were submitted in late May, regulators are moving slowly on the sale of Spokane-based Western United Life Assurance Co., Old Standard Life Insurance Co., of Idaho, and Old West Annuity and Life Insurance Co., of Arizona. The three companies were offered for sale as a package deal with the goal of earning cash for thousands of Metropolitan creditors.
