In addition, the corporation has increased its target corporate debt level to $6.8 billion, including $5.8 billion for Georgia-Pacific Group, up from $4.75 billion to reflect financing incurred for the Unisource merger. Assuming continued strong operating results and cash flow, the group anticipates resuming share repurchases. Unisource, formerly North America's largest independent marketer and distributor of printing and imaging paper and supply systems, will conduct business under its existing name as a separate distribution subsidiary of Georgia-Pacific Group. As a result of this transaction, Unisource common stock will be delisted from the New York Stock Exchange and it will cease to be a Securities and Exchange Commission reporting company. Combined revenues of the merged companies exceeded $20 billion last year. -more- -2- "Since our merger agreement was first announced, we have been aggressively focusing on a strategy that will transform Unisource and optimize the synergies between its distribution business and Georgia-Pacific," said A.D. "Pete" Correll, chairman and chief executive officer of Georgia-Pacific Corp. "We expect to be able to achieve immediate operational improvements and to make hard-cost savings by reducing overhead and eliminating the overlaps inherent in these businesses. "At the same time, Georgia-Pacific Group's essential financial objectives remain firmly in place. Those objectives are to generate returns over the business cycle that exceed the cost of capital, limit our capital spending, target the group to operate below its debt-level ceiling and distribute excess free cash flow to shareholders through share repurchases," Correll said. "Together with our strategy to own and operate a fortified commercial tissue business through our recently announced Wisconsin Tissue partnership, Georgia-Pacific Group has further strengthened its position to compete in our industry with solid cash flows and diverse earnings capability."
