New Reportable Business Segments	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. As a result of this new alignment, the Company began reporting under its new reportable segments in connection with the Company’s Quarterly Report on Form 10-Q for the first quarter of 2022. As part of this Quarterly Report on Form 10-Q, the Company has included 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.
Discontinued Operations	Discontinued Operations The Company reports a component of an entity or group of components of an entity as a discontinued operation and held for sale upon acquisition, if the Company has (i) executed a plan to sell the business as of the acquisition date or (ii) has begun to formulate a plan to sell the business and either currently meets or expects to meet the held for sale criteria within three months. An entity meets the held for sale criteria when (a) management, having the authority to approve the action, commits to a plan to sell the discontinued operation, the plan of which is unlikely to have any significant changes or to be withdrawn, (b) the completed sale is probable within one year, and (c) an active program to locate a buyer has been initiated with the operation actively marketed for sale at a price that is reasonable in relation to its current fair value and for immediate sale in its present condition. The Company separately accounts for the operating results and related cash flows associated with discontinued operations until such operations are divested; such discontinued operations are reported separately from the operating results and related cash flows associated with continuing operations in the accompanying Condensed Consolidated Financial Statements.
