09 Mar 2017 --- Dutch paints and chemicals maker AkzoNobel NV has rejected an unsolicited €20.9 billion ($22.1 billion) offer from US peer PPG Industries Inc. PPG is working with advisers to study a transaction that could involve acquiring all or part of Amsterdam-based Akzo, the second-biggest paint maker with a market value of about $17 billion. A deal between PPG, with a market valuation of about $25.9 billion, and Akzo would create a global leader in specialty chemicals.
