Significant accounting estimates include, but not limited to, depreciable lives of property, plant and equipment and intangible assets, the realization of deferred income tax assets, future warranty expenses, current expected credit loss and discount rate for operating leases. Changes in facts and circumstances may result in revising estimates. Actual results could differ from those estimates, and as such, differences may be material to the consolidated financial statements.</p>

These factors are estimates that may change based on new information that becomes available during the reported period. The portion of the warranty reserve expected to be incurred within the next 12 months is included within accrued expenses and other current liabilities while the remaining balance is included within other non-current liabilities on the consolidated balance sheets.</p>
