International Paper Chairman & CEO Andrew Silvernail discusses the company's improvement plan taking shape and equity outlook. International Paper has outlined early steps to improve performance, including boosting Ebitda to $4 billion in the medium term from $2 billion over the past 12 months. Costs savings are expected to account for $1.2 billion of the boost, with the remaining $800 million from its new commercial strategy. This is on top of integrating the DS Smith acquisition, which is projected to close in January. Execution is a risk since the shift represents a complete change in mindset from running mills full out. Silvernail spoke with Bloomberg's Alix Steel and Paul Sweeney
