These financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with Article 10 of SEC Regulation S-X.

Operating results for the period ended June 30, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013. These condensed consolidated financial statements should be read in conjunction with PCA’s Annual Report on Form 10-K for the year ended December 31, 2012.
