Redeemable Noncontrolling Interest, Equity, Carrying Amount [Abstract] |
Redeemable Non-controlling Interest | Note 17 – Redeemable Non-Controlling Interest As of December 31, 2023 and 2022, the non-controlling Adtran Networks stockholders’ equity ownership percentage in Adtran Networks was approximately 34.7% and 34.7%, respectively. As a result of the effectiveness of the DPLTA on January 16, 2023, the Adtran Networks shares, representing the equity interest in Adtran Networks held by holders other than the Company, can be tendered at any time and are, therefore, redeemable and must be classified outside stockholders’ equity. Therefore, the permanent equity noncontrolling interest balance was reclassified to redeemable non-controlling interest (RNCI) on January 16, 2023 and was remeasured to fair value based on the trading market price of the Adtran Networks shares. Subsequently, the carrying value of the RNCI is adjusted to its maximum redemption value at each reporting date when the maximum redemption value is greater than the initial carrying amount of the RNCI. However, the RNCI will be remeasured using the current exchange rate at each reporting date as long as the RNCI is currently redeemable. For the period of time that the DPLTA is in effect, the RNCI will continue to be presented as RNCI outside of stockholders’ equity in the Condensed Consolidated Balance Sheets. The following table summarizes the redeemable non-controlling interest activity for the year ended December 31, 2023:

Annual recurring compensation payable on untendered outstanding shares under the DPLTA must be recognized as it is accrued. For the year ended December 31, 2023, we have recognized $11.5 million representing the portion of the annual recurring cash compensation to the non-controlling shareholders accrued during such periods, which will be paid after the ordinary general shareholders' meeting of Adtran Networks beginning in 2024. See Note 1 and Note 20 for additional information on RNCI and the annual dividend.
