Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated interim financial statements of KVH Industries, Inc. and its wholly owned subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States of America. The Company has evaluated all subsequent events through the date of this filing. All significant intercompany accounts and transactions have been eliminated in consolidation. The 2022 consolidated interim financial statements reflect the sale of the inertial navigation business as discontinued operations. See Notes 1 and 16 for further information on the sale of the inertial navigation business. The consolidated interim financial statements have not been audited by the Company’s independent registered public accounting firm and include all adjustments (consisting of only normal recurring adjustments) which are, in the opinion of management, necessary for a fair presentation of the financial condition, results of operations, and cash flows for the periods presented. These consolidated interim financial statements do not include all disclosures associated with annual financial statements and accordingly should be read in conjunction with the Company’s consolidated financial statements and related notes included in the Company’s annual report on Form 10-K for the year ended December 31, 2022 filed on March 16, 2023 with the Securities and Exchange Commission. The results for the three and nine months ended September 30, 2023 are not necessarily indicative of operating results for the remainder of the year. Significant Estimates and Assumptions and Other Significant Non-Recurring Transactions The preparation of interim 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 as of the date of the interim financial statements and the reported amounts of sales and expenses during the reporting periods. As described in the Company’s annual report on Form 10-K, the estimates and assumptions used by management affect the Company’s revenue recognition, valuation of accounts receivable, valuation of inventory, expected future cash flows including growth rates, discount rates, terminal values and other assumptions and estimates used to evaluate the recoverability of long-lived assets and goodwill, estimated fair values of long-lived assets, including goodwill, amortization methods and periods, certain accrued expenses and other related charges, stock-based compensation, contingent liabilities, forfeitures and key valuation assumptions for its share-based awards, estimated fulfillment costs for warranty obligations, tax reserves and recoverability of the Company’s net deferred tax assets and related valuation allowance, and the valuation of right-of-use assets and lease liabilities. Although the Company regularly assesses these estimates, actual results could differ materially from these estimates. Changes in estimates are recorded in the period in which they become known. The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances. Foreign Currency Translation The financial statements of the Company’s foreign subsidiaries located in Denmark and Singapore are maintained using the United States dollar as the functional currency. Exchange rates in effect on the date of the transaction are used to record monetary assets and liabilities. Revenue and other expense elements are recorded at rates that approximate the rates in effect on the transaction dates. Foreign currency exchange gains and losses are recognized within “other (expense) income, net” in the accompanying consolidated statements of operations. The Company recorded a total of net foreign currency exchange gains (losses), which are comprised of both realized and unrealized foreign currency exchange gains and losses, in its accompanying consolidated statements of operations of $92 and $450 for the three months ended September 30, 2023 and 2022, respectively, and $(18) and $1,009 for the nine months ended September 30, 2023 and 2022, respectively. The financial statements of the Company’s foreign subsidiaries located in the United Kingdom, Brazil, Norway, Cyprus, India and Japan use the foreign subsidiaries’ respective local currencies as the functional currency. The Company translates the assets and liabilities of these foreign subsidiaries at the exchange rates in effect at the end of each reporting period. Net sales, costs and expenses are translated using average exchange rates in effect during the period. Gains and losses from foreign currency translation are credited or charged to accumulated other comprehensive loss included in stockholders' equity in the accompanying consolidated balance sheets. CEO Executive Employment Agreement In May 2022, the Company entered into an executive employment agreement with Brent C. Bruun in order to retain his services and provide him with certain benefits in the event that the Company terminates his employment without cause (as defined in the agreement) or Mr. Bruun terminates his employment for good reason (as defined in the agreement) (either such termination, a “Qualifying Termination”), including following a change in control. The agreement provided that, if Mr. Bruun continued to serve as an employee through December 31, 2022 (the “Retention Date”), the Company would pay him a retention bonus equal to 75% of his base salary on the agreement date, and the Company would accelerate the vesting of his equity awards that would otherwise have vested in the twelve months after the Retention Date. On October 11, 2022, the Company entered into an amendment to the employment agreement with Mr. Bruun that, among other things, increased his annual base salary to $448 per year, retroactive to July 1, 2022, increased his target annual incentive compensation for the second half of 2022 to 80% of his base salary (without changing his target annual incentive compensation for the first half of 2022), extended his Retention Date from December 31, 2022 to December 31, 2023, which effectively extended the period during which Mr. Bruun must remain employed by the Company in order to earn his retention bonus, and modified the amount of the retention bonus from 75% of his base salary in effect on May 2, 2022 to 75% of the highest base salary in effect for Mr. Bruun on or before the date he becomes entitled to receive the retention bonus or the “Partial Retention Bonus” (as defined in the employment agreement). If a Qualifying Termination occurs before December 31, 2023, Mr. Bruun will receive a pro rata portion of the retention bonus. If in connection with such a termination he becomes entitled to receive the change in control severance payments and benefits, he will also become entitled to receive the full retention bonus, and the Retention Date will be the later of the date of such change in control or such termination of employment. The amendment did not modify the terms of the employment agreement relating to acceleration of vesting of certain equity awards if Mr. Bruun remains employed by the Company through December 31, 2022. As of September 30, 2023, the Company has accrued approximately $286 for the retention bonus payable to Mr. Bruun. Contemporaneously with the amendment to Mr. Bruun’s employment agreement, the Compensation Committee also granted Mr. Bruun a restricted stock award and a non-statutory stock option, which together had an aggregate grant date fair value of approximately $100. The restricted stock award and the non-statutory stock option have terms that are materially consistent with the previously disclosed terms of similar grants to the Company’s executive officers.
