12. PRODUCT WARRANTY

The Company estimates its warranty costs at the time of revenue recognition based on historical warranty claims experience and records the expense in cost of sales. The warranty accrual balance is reviewed quarterly to establish that it materially reflects the remaining obligation based on the anticipated future expenditures over the balance of the obligation period. Adjustments are made when the actual warranty claim experience differs from estimates.
