The financial statements have been prepared in conformity with generally accepted accounting principles in the United States of America (U.S. GAAP) and pursuant to the rules and regulations of the Securities and Exchange Commission (SEC).  Certain amounts for prior periods have been reclassified to conform to the current period presentation.  The investing activities on the Consolidated Statements of Cash Flows have additions and collections related to Caterpillar purchased receivables presented on a net basis.  These receivables have short durations with a high turnover rate.  The total cash flows for investing activities have not changed.Interim results are not necessarily indicative of results for a full year.  The information included in this Form 10-Q should be read in conjunction with Management's Discussion and Analysis of Financial Condition and Results of Operations and the audited consolidated financial statements and notes thereto included in our annual report on Form 10-K for the year ended December 31, 2011.  The December 31, 2011 financial position data included herein was derived from the audited consolidated financial statements included in our annual report on Form 10-K for the year ended December 31, 2011, but does not include all disclosures required by U.S. GAAP.We consolidate all variable-interest entities (VIEs) where we are the primary beneficiary.  For VIEs, we assess whether we are the primary beneficiary as prescribed by the accounting guidance on the consolidation of VIEs.  The primary beneficiary of a VIE is the party that has the power to direct the activities that most significantly impact the performance of the entity and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the entity.
