AT Atlantic Power Corporation

Alltel (NYSE:AT) today announced it has begun a formal process to assess the market environment for strategic repositioning options related to its wireline business. The company announced in January that it would undertake a thorough review of the strategic alternatives related to its wireline business. During the ensuing months, Alltel reviewed various capital structures and strategic alternatives that could be value enhancing to its stockholders. The formal process currently underway will assess the market appetite for the wireline repositioning options that Alltel's review concluded could enhance value for its stockholders. Early indications are encouraging, and Alltel will provide a further update when it announces third-quarter earnings results in late October.
