| Basis of Presentation                                                               | Basis of Presentation In the opinion of management, the accompanying unaudited consolidated financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of (a) the consolidated profit for the three and six months ended June 30, 2018 and 2017, (b) the consolidated comprehensive income for the three and six months ended June 30, 2018 and 2017, (c) the consolidated financial position as of June 30, 2018 and December 31, 2017, (d) the consolidated changes in shareholder's equity for the six months ended June 30, 2018 and 2017 and (e) the consolidated cash flows for the six months ended June 30, 2018 and 2017.  The preparation of financial statements, 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), requires management to make estimates and assumptions that affect reported amounts.  Significant estimates include residual values for leased assets, allowance for credit losses and income taxes.  Actual results may differ from these estimates.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 the audited consolidated financial statements and notes thereto included in our annual report on Form 10-K for the year ended December 31, 2017 (2017 Form 10-K) filed with the SEC on February 15, 2018.  The December 31, 2017 financial position data included herein was derived from the audited consolidated financial statements included in the 2017 Form 10-K, but does not include all disclosures required by U.S. GAAP.  Certain amounts for prior periods have been reclassified to conform with current period financial statement presentation.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 both the power to direct the activities that most significantly impact the entity’s economic performance and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the entity.  Please refer to Note 7 for more information. We have customers and dealers that are VIEs of which we are not the primary beneficiary. Although we have provided financial support to these entities and therefore have a variable interest, we do not have the power to direct the activities that most significantly impact their economic performance.  Our maximum exposure to loss from our involvement with these VIEs is limited to the credit risk inherently present in the financial support that we have provided. These risks are evaluated and reflected in our financial statements as part of our overall portfolio of finance receivables and related allowance for credit losses. |
