Aetna Inc. said Tuesday afternoon it would reorganize its business units ahead of its expected acquisition by CVS Health Corp. Aetna said it would break its business down into a health-care segment and a "Corporate/Other" category, which will include discontinued products, divested contracts and corporate expenses that do not support Aetna's business operations. The company restated previous financial statements to reflect the change in Tuesday's announcement, and will present financials in the new fashion when reporting first-quarter earnings May 1. CVS announced plans to buy Aetna for about $69 billion in cash and stock last December.
