Net warranty charges incurred include labor charges and costs of replacement parts for system repairs under warranty. These costs are recorded net of any estimated cost recoveries resulting from either successful repair of damaged parts or from warranties offered by the Company’s suppliers for defective components. The provision for warranty charges reflects the estimate of future anticipated net warranty costs to be incurred for all products under warranty at quarter end and is recorded to cost of sales. Of the total of $9.0 million and $4.9 million of product warranty accruals as of December 30, 2017 and December 31, 2016, $4.5 million and $0.8 million were non-current and were included in Other liabilities on the Condensed Consolidated Balance Sheets.
