NatureOfOperations
Description of business: Communications Systems, Inc. is a Minnesota corporation organized in 1969 that until August 2, 2021 classified its business into two segments: (1) the Electronics & Software segment (consisted of US-based subsidiary Transition Networks and UK-based subsidiary Net2Edge) which (i) manufactured and sold solutions that provide actionable intelligence, power and connectivity at the edge of networks through PoE products, software and services as well as traditional products such as media converters, network adapters and other connectivity products and (ii) designed, developed, and sold edge network access products, TDM (time-division multiplexing) over IP and other circuit emulation solutions, along with specialized cloud-based software solutions, primarily within the telecommunications market; and (2) the Services and Support segment (consisting of subsidiaries JDL and Ecessa), which (i) provides technology solutions including virtualization, managed services, wired and wireless network design and implementation, and hybrid cloud infrastructure and deployment and (ii) designs, develops, and sells SD-WAN (software-designed wide-area network) solutions. As previously disclosed, on August 2, 2021, the Company and Lantronix, Inc. (“Lantronix”) completed the sale by CSI to Lantronix of all of the issued and outstanding stock of CSI’s wholly owned subsidiary, Transition Networks, Inc., and the entire issued share capital of its wholly owned subsidiary, Transition Networks Europe Limited (collectively with Transition Networks, Inc., the “TN Companies”), pursuant to the securities purchase agreement dated April 28, 2021 (“E&S Sale Transaction”). As a result, sales and expenses related to the operations of the former Electronics & Software segment have been presented as discontinued operations in this Form 10-K. For purposes of this Form 10-K, the Company classifies operations as those from its Services & Support segment. Non-allocated general and administrative expenses are separately accounted for as “Other” in the Company’s segment reporting. Intersegment revenues are eliminated upon consolidation.

CY2021 us-gaap Use Of Estimates
UseOfEstimates
Use of estimates: The presentation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company uses estimates based on the best information available in recording transactions and balances resulting from operations. Actual results could differ from those estimates. The Company’s estimates consist principally of reserves for doubtful accounts, sales returns, warranty costs, asset impairment evaluations, accruals for compensation plans, self-insured medical and dental accruals, lower of cost or market inventory adjustments, provisions for income taxes and deferred taxes, and depreciable lives of fixed assets.
