For purposes of this report, any reference to “Potlatch,” “the company,” “we,” “us,” and “our” means Potlatch Corporation and all of its wholly owned subsidiaries, except where the context indicates otherwise.

The accompanying Consolidated Statements of Income and Consolidated Statements of Comprehensive Income for the quarters and six months ended June 30, 2013 and 2012, the Consolidated Condensed Balance Sheets at June 30, 2013 and December 31, 2012, and the Consolidated Condensed Statements of Cash Flows for the six months ended June 30, 2013 and 2012 have been prepared in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP). We believe that all adjustments necessary for a fair statement of the results of such interim periods have been included.
