Subsequent Events	Note 16—Subsequent Events 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. All businesses previously reported in the Interconnect Products and Assemblies segment have now been aligned with one of the three newly formed segments. All businesses previously reported in the Cable Products and Solutions segment have now been aligned with our newly formed Communications Solutions segment. This new alignment reinforces the Company’s entrepreneurial culture and the clear accountability of each of our business unit general managers, while enhancing the scalability of Amphenol’s business for the future. The segment structure reflects the manner in which the Chief Operating Decision Maker (“CODM”), who is the Company’s Chief Executive Officer, regularly assesses information for decision-making purposes, including the allocation of resources, effective January 1, 2022. In conjunction with the new alignment of our business, the Company appointed three new segment managers to lead their respective reportable business segments, each reporting directly to the Company’s Chief Executive Officer. The Company’s three new reportable business segments have been identified as: ●Harsh Environment Solutions – the Harsh Environment Solutions segment designs, manufactures and markets a broad range of ruggedized interconnect products, including connectors and interconnect systems, printed circuits and printed circuit assemblies and other products for use in the industrial, military, commercial aerospace, automotive, mobile networks and information technology and data communications end markets. ●Communications Solutions – the Communications Solutions segment designs, manufactures and markets a broad range of connector and interconnect systems, including high speed, radio frequency, power, fiber optic and other products, together with antennas, for use in the information technology and data communications, mobile devices, industrial, mobile networks, broadband communications, automotive, commercial aerospace and military end markets. ●Interconnect and Sensor Systems – the Interconnect and Sensor Systems segment designs, manufactures and markets a broad range of sensors, sensor-based systems, connectors and value-add interconnect systems used in the automotive, industrial, information technology and data communications, mobile networks, military and commercial aerospace end markets. The Company is in the process of completing the update of its internal reporting to accommodate this new reporting segment structure. The Company will begin reporting its new reportable segments in connection with its Quarterly Report on Form 10-Q for the quarterly period ending March 31, 2022, including the recasting of relevant prior year period segment information for conformity of presentation.
