Basis of Presentation and Principles of Consolidation	Note 1—Basis of Presentation and Principles of Consolidation The Condensed Consolidated Balance Sheets as of March 31, 2022 and December 31, 2021, and each of the related Condensed Consolidated Statements of Income, Condensed Consolidated Statements of Comprehensive Income and Condensed Consolidated Statements of Cash Flow for the three months ended March 31, 2022 and 2021, include the accounts of Amphenol Corporation and its subsidiaries (“Amphenol,” the “Company,” “we,” “our” or “us”). All material intercompany balances and transactions have been eliminated in consolidation. The condensed consolidated financial statements included herein are unaudited. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, including normal recurring adjustments considered necessary for a fair presentation of the results, in conformity with accounting principles generally accepted in the United States of America. The results of operations for the three months ended March 31, 2022 are not necessarily indicative of the results to be expected for the full year. These condensed consolidated financial statements and the related notes should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021 (the “2021 Annual Report”). New Reportable Business Segments Effective January 1, 2022, the Company aligned its businesses into three newly formed reportable business segments: (i) Harsh Environment Solutions, (ii) Communications Solutions and (iii) Interconnect and Sensor Systems. This new alignment replaces our historic reportable business segments. The Company has begun reporting under its new reportable segments in connection with this Quarterly Report on Form 10-Q, which also includes the recasting of relevant prior year period segment information in order to enable year-over-year segment comparisons. Refer to Note 13 herein for further details related to the Company’s change in its reportable business segments effective January 1, 2022. We have determined that the Company’s reporting units are the three new reportable business segments. As a result of the new reporting segment structure, the Company utilized the relative fair value allocation approach to reallocate the historical goodwill associated with the previous Interconnect Products and Assemblies segment, while the historical goodwill associated with the previous Cable Products and Solutions segment has been allocated in full to the newly formed Communications Solutions segment. The Company will continue to perform its evaluation for the impairment of goodwill associated with its reporting units on an annual basis as of each July 1 or more frequently if an event occurs or circumstances change that would indicate that a reporting unit’s carrying amount may be impaired. Refer to Note 12 herein for further details related to the carrying amount of goodwill by segment.
