These estimates and underlying assumptions can impact all elements of our consolidated financial statements. For example, in the Consolidated Statements of Income, estimates are used when accounting for deductions from revenue (such as rebates, sales allowances, product returns and discounts), determining cost of sales, allocating cost in the form of depreciation and amortization, and estimating restructuring charges and the impact of contingencies. On the Consolidated Balance Sheets, estimates are used in determining the valuation and recoverability of assets, such as accounts receivables, inventories, fixed assets, goodwill and other identifiable intangible assets, and estimates are used in determining the reported amounts of liabilities, such as taxes payable, uncertain tax positions, benefit obligations, the impact of contingencies, deductions from revenue and restructuring reserves, all of which also impact the Consolidated Statements of Income. </span></div><div style="line-height:120%;padding-bottom:8px;padding-top:8px;text-align:left;font-size:9pt;"><span style="font-family:inherit;font-size:9pt;">Our estimates are often based on complex judgments, probabilities and assumptions that we believe to be reasonable but that can be inherently uncertain and unpredictable. If our estimates and assumptions are not representative of actual outcomes, our results could be materially impacted. </span></div><div style="line-height:120%;padding-bottom:8px;padding-top:8px;text-align:left;font-size:9pt;"><span style="font-family:inherit;font-size:9pt;">As future events and their effects cannot be determined with precision, our estimates and assumptions may prove to be incomplete or inaccurate, or unanticipated events and circumstances may occur that might cause us to change those estimates and assumptions. We are subject to risks and uncertainties that may cause actual results to differ from estimated amounts, such as changes in competition, litigation, legislation and regulations. We regularly evaluate our estimates and assumptions using historical experience and expectations about the future. We adjust our estimates and assumptions when facts and circumstances indicate the need for change. Those changes generally will be reflected in our consolidated financial statements on a prospective basis unless they are required to be treated retrospectively under relevant accounting standards. It is possible that others, applying reasonable judgment to the same facts and circumstances, could develop and support a range of alternative estimated amounts. </span></div>
