Maybe you missed it Dave, but the article clearly says:
"Aetna said the profit boost was "largely the result of higher commercial underwriting margins driven by management actions to appropriately price the business," along with lower health care use. Aetna had struggled through 2009 with medical costs that climbed higher than the company expected when it set prices for that year. Company leaders said then that they repriced a significant portion of Aetna's commercial insurance business."

And...

"The Hartford, Conn., company also said its fourth-quarter net income rose 30 percent due in part to better pricing and a slowdown in health care use that also has helped its competitors in the last few months of 2010."

God forbid a corporation makes a profit!!!
