[1] | Payments for 2016, 2015 and 2014 included $2.3 million, $8.4 million and $26.6 million, respectively, to repair homes affected by water intrusion-related issues in certain of our communities in central and southwest Florida.
[2] | These expenses are included in selling, general and administrative expenses and are largely offset by contributions from independent subcontractors participating in the wrap-up policy
[3] | Adjustments for 2016, 2015 and 2014 included the reclassification of certain estimated minimum probable recoveries to receivables in connection with the above-noted water intrusion-related issues. Adjustments in 2014 also included the reclassification of estimated minimum probable recoveries to establish a separate accrual for a water intrusion-related inquiry, as described below. The adjustments for each year had no impact on our consolidated statements of operations. There were no estimated minimum probable recoveries netted against our warranty liability at November 30, 2016.
