In the second and third quarters of 2016, a business unit in the Windows and Other Specialty Products segment recorded $10 million and $21 million, respectively, for increases in its estimate of expected future warranty claims relating to previously sold windows and doors. The change in estimate resulted from the adoption of an improved warranty valuation model and the availability of additional information used to support the estimate of costs to service claims and recent warranty claims trends, including a shift to increased costs to repair.
