Dividend Policy

PCA expects to continue to pay regular cash dividends, although there is no assurance as to the timing or level of future dividend payments because these depend on future earnings, capital requirements, and financial condition. The timing and amount of future dividends are subject to the determination of PCA’s Board of Directors.

On August 31, 2016, PCA announced an increase of its quarterly cash dividend on its common stock from an annual payout of $2.20 per share to an annual payout of $2.52 per share. The first quarterly dividend of $0.63 per share was paid on October 14, 2016 to shareholders of record as of September 15, 2016.

During the year ended December 31, 2017, we paid $237.6 million of dividends to shareholders. On December 14, 2017 PCA's Board of Directors approved a regular quarterly cash dividend of $0.63 per share of common stock, which was paid on January 12, 2018 to shareholders of record as of December 26, 2017. The dividend payment was $59.4 million.

Stock Repurchase Program

On February 25, 2016, PCA announced that its Board of Directors authorized the repurchase of $200.0 million of the Company's outstanding common stock. At the time of the announcement, there was no remaining authority under previously announced programs. 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.

The Company did not repurchase any shares of its common stock under this authority during the year ended December 31, 2017. In 2016, we paid $100.3 million to repurchase 1,987,187 shares of common stock which fully depleted the $93.3 million of repurchase authority under previous authorizations by our board of directors. In 2015, we paid $154.7 million to repurchase 2,326,493 shares of common stock. As of December 31, 2017, we are authorized to repurchase $193.0 million of the Company’s common stock.
