Hirsch Electronics Corporation (“Hirsch”) Acquisition – Secure Keyboards and Secure Networks. Prior to the Company’s acquisition of Hirsch in 2009, in November 1994, Hirsch had entered into a settlement agreement (the “1994 Settlement Agreement”) with two limited partnerships, Secure Keyboards, Ltd. (“Secure Keyboards”) and Secure Networks, Ltd. (“Secure Networks”). On April 8, 2009, the 1994 Settlement Agreement was amended and restated to replace the royalty-based payment arrangement with an installment payment schedule with contractual payments to be made in future periods through 2021 (the “2009 Settlement Agreement”). On April 30, 2009, as part of the acquisition of Hirsch, the Company provided Secure Keyboards and Secure Networks with a limited guarantee of Hirsch’s payment obligation under the 2009 Settlement Agreement.

On April 13, 2020, the Company, Secure Keyboards, and Secure Networks, amended the 2009 Settlement Agreement. The amendment reduced the amount of quarterly payments due under the obligation in 2020, and requires three additional quarterly payments in 2021. The Company’s remaining payment obligation under the 2009 Settlement Agreement, as amended, was extended through October 31, 2021. The Company included approximately $14,000 and $33,000 of interest expense during the three and six months ended June 30, 2021, respectively, and approximately $55,000 and $87,000 of interest expense during the three and six months ended June 30, 2020, respectively, in its condensed consolidated statements of comprehensive income (loss) for interest accreted on the payment obligation.
