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 six months ended June 30, 2020 and 2019. For the three and six months ended June 30, 2020 and 2019, we recorded adjustments to decrease our warranty accrual due to lower than expected general warranty related expenditures in certain close of escrow years.
