The Wall Street Journal: Florida Insurance Regulator Approves Aetna's Acquisition Of Humana Florida's insurance regulator approved Aetna Inc.'s acquisition of Humana Inc., and required no divestitures, an important win for the companies from a state that is a key market.

But Florida is a cornerstone of Humana's Medicare franchise, so its review was closely watched. (Wilde Mathews, 2/15)
