Note 1: Basis of Presentation

We prepared our interim consolidated condensed financial statements that accompany these notes in conformity with U.S. generally accepted accounting principles, consistent in all material respects with those applied in our Annual Report on Form 10-K for the year ended December 31, 2011.

We have a 52- or 53-week fiscal year that ends on the last Saturday in December. Fiscal year 2012 is a 52-week fiscal year, and each quarter is a 13-week quarter. Fiscal year 2011 was a 53-week fiscal year, and the first quarter of 2011 was a 14-week quarter.

We have made estimates and judgments affecting the amounts reported in our consolidated condensed financial statements and the accompanying notes. The actual results that we experience may differ materially from our estimates. The interim financial information is unaudited, but reflects all normal adjustments that are, in our opinion, necessary to provide a fair statement of results for the interim periods presented. This interim information should be read in conjunction with the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2011.
