Schedule of Product Warranty Liability

The table set forth below summarizes accrual, adjustment and payment activity related to our warranty accrual for the three and nine months ended September 30, 2024 and 2023. The warranty accrual during the nine months ended September 30, 2024 increased due to a $3.1 million adjustment to increase our warranty accrual during the period. This adjustment was due to higher general warranty related expenditures.
