Cigna cut its reserve addition in half.

The insurer said only $600 million of the previously announced $1.2-billion infusion will be placed in reserves, the balance to be made up of interest earnings from the cash reserve--a strategy that will take up to 15 years to accomplish, the company said. The move raised eyebrows among regulators in Connecticut and Pennsylvania who questioned the counting of anticipated income as reserves against higher property and casualty claims, calling it “different” and “unusual.” But Cigna justified its action by saying that “in many instances these claims will not be paid until a far- distant day.”
