Packaging Corporation of America (NYSE: PKG) announced today that its Board of Directors has authorized the repurchase of an additional $150 million of the company's outstanding common stock. Together with remaining authority under previously announced programs, the company may repurchase approximately $205 million of additional shares. Repurchases may be made from time to time in open market or privately negotiated transactions in accordance with applicable securities regulations. The timing and amount of repurchases will be determined by the company in its discretion based on factors such as PCA's stock price and market and business conditions. Commenting on the additional authorization, Mark W. Kowlzan, Chief Executive Officer of PCA, said, "This share repurchase program, together with our dividend increase announced earlier this year, demonstrates PCA's strong operating performance and cash generation as well as its continuing commitment to return value to our shareholders." PCA is the fourth largest producer of containerboard and corrugated packaging products in the United States and the third largest producer of uncoated freesheet paper in North America. PCA operates eight paper mills and 94 corrugated products plants and related facilities. Some of the statements in this press release are forward-looking statements. Forward-looking statements include statements about our future intent to repurchase shares.
