Correction

In a recent Business Page article on the Aetna Life & Casualty Company, certain information was inadvertently omitted. Aetna's purchase of Federated Investors Inc. and Geosource Inc. involved a tax-free exchange of newly issued Aetna stock. The acquisition of the Samuel Montagu & Co. Group, a British merchant bank, was a cash purchase of 40 percent of Montagu. Also, the purchase prices of Montagu and Federated were transposed. Montagu was bought for $115 million; Federated, for $185 million.
