Spin Off [Abstract]
Spin-Off	O.Spin-Off In late 2021, the Company’s Board approved progressing with the Spin-Off (as defined below) of M-tron Industries, Inc. (together with its subsidiaries, “MtronPTI”) which is currently a wholly-owned subsidiary of the Company. On May 11, 2022, the Company filed a Definitive Proxy Statement with the SEC indicating its intention to secure stockholder approval of the transaction. A special meeting of stockholders to vote on the Spin-Off will be held on June 21, 2022. If approved by the Company’s stockholders, the Spin-Off will separate the business activities and investments of the Company and create two separate, publicly-traded companies: (1) the Company, which will continue to own and operate Precise Time and Frequency, LLC and hold substantially all the Company’s cash and marketable securities, and (2) MtronPTI, which includes the operations of Piezo Technology, Inc. and M-tron Asia, LLC (the “Spin-Off”). The Spin-Off, if approved by the Company’s stockholders, is expected to be effected through a pro rata issuance of shares of MtronPTI’s common stock to the Company’s stockholders structured as a tax-free distribution. Stockholders of the Company will receive one share of MtronPTI’s common stock for each share of the Company’s common stock held of record as of the close of business on the record date for the distribution. As a result, the Company’s stockholders as of the record date for the Spin-Off will also become the stockholders of MtronPTI after the Spin-Off. The Company will cease to have any ownership interest in MtronPTI following the Spin-Off, but the Company’s stockholders will, unless they sell their shares, be the stockholders of both the Company and MtronPTI. Management believes that, if completed, the potential Spin-Off of MtronPTI would enable stockholders to more clearly evaluate the performance and future potential of each entity on a standalone basis, while allowing each entity to pursue its own distinct business strategy and capital allocation policy. Separating MtronPTI as an independent, publicly-owned company positions both MtronPTI and LGL Group to create value for their respective stockholders. The Spin-Off would permit each company to tailor its strategic plans and growth opportunities, more efficiently raise and allocate resources, including capital raised through debt or equity offerings, provide flexibility to use its own stock as currency for incentive compensation and potential acquisitions and provide investors a more targeted investment opportunity. If stockholder approval of the Spin-Off transaction is obtained, the Company anticipates reporting MtronPTI as a discontinued operation. There can be no assurance that the potential Spin-Off transaction will be completed in the manner described above, or at all.

O.Spin-Off

In late 2021, the Company’s Board approved progressing with the Spin-Off (as defined below) of M-tron Industries, Inc. (together with its subsidiaries, “MtronPTI”) which is currently a wholly-owned subsidiary of the Company. On May 11, 2022, the Company filed a Definitive Proxy Statement with the SEC indicating its intention to secure stockholder approval of the transaction. A special meeting of stockholders to vote on the Spin-Off will be held on June 21, 2022. If approved by the Company’s stockholders, the Spin-Off will separate the business activities and investments of the Company and create two separate, publicly-traded companies: (1) the Company, which will continue to own and operate Precise Time and Frequency, LLC and hold substantially all the Company’s cash and marketable securities, and (2) MtronPTI, which includes the operations of Piezo Technology, Inc. and M-tron Asia, LLC (the “Spin-Off”).

The Spin-Off, if approved by the Company’s stockholders, is expected to be effected through a pro rata issuance of shares of MtronPTI’s common stock to the Company’s stockholders structured as a tax-free distribution. Stockholders of the Company will receive one share of MtronPTI’s common stock for each share of the Company’s common stock held of record as of the close of business on the record date for the distribution. As a result, the Company’s stockholders as of the record date for the Spin-Off will also become the stockholders of MtronPTI after the Spin-Off.
