In March 2018, and as amended in December 2020, the Company entered into an agreement with a vendor to develop a certain software product and related enhancements pursuant to which the Company is obligated to make revenue-share payments under the program, subject to aggregate fixed revenue-share payments of $15.8 million. The payments are based on a revenue-share rate applied to revenue from the developed-product and the corresponding hardware sales through March 2024. If the minimum revenue-share payments are not achieved by the end of that period, a true-up payment will be due. As of October 1, 2022, the liability, including accrued interest, was $12.7 million, of which $10.3 million is included in “Accrued liabilities” and $2.4 million in “Other long-term liabilities” in the accompanying Condensed Consolidated Balance Sheet. As of December 31, 2021, the liability, including accrued interest, was $13.2 million, of which $4.7 million was included in “Accrued liabilities” and $8.5 million in other “Other long-term liabilities.”
