Cigna CEO David Cordani delivered a similar message to the conference Tuesday.

Though early enrollment in the exchanges and the mix of healthy and sick beneficiaries “is not what everybody anticipated, I would underscore this may present an attractive long-term opportunity,” he insisted.

He said Cigna had made a decision early on to only participate in a limited number of markets as implementation began, and ended up offering plans on the exchanges of five states.

Jay Gellert, the CEO of Health Net, a managed care company that has a Medicaid business and a large presence in the California insurance market, was extremely bullish on the law.

“We’re all in in the ACA,” Gellert said. “We’re all in and we’re happy we are.”
