The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses, and related disclosure of contingent assets and liabilities during the reporting period. The more significant estimates include: (1) revenue recognition; (2) the valuation allowances for trade and other receivables, loans receivable and inventories; (3) the valuation of goodwill, indefinite-lived intangible assets, long-lived assets and associated companies; (4) the valuation of deferred tax assets; (5) contingencies, including legal and environmental liabilities; (6) fair value of derivatives; (7) post-employment benefit liabilities; (8) estimates and assumptions used in the determination of fair value of certain securities; and (9) estimates of loan losses. Actual results may differ from the estimates used in preparing the consolidated financial statements; and, due to substantial holdings in and/or restrictions on certain investments, the value that may be realized could differ from the estimated fair value.</span></div>
