[1] As discussed below, adjustments in 2015 and 2014 were primarily comprised of the reclassification of estimated minimum probable recoveries to receivables. Adjustments in 2014 also included a reclassification of estimated minimum probable recoveries to establish a separate accrual for a water intrusion-related inquiry. Adjustments in 2013 were comprised of charges associated with water intrusion-related issues 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] Recoveries are reflected in the period we receive funds from independent subcontractors and/or their insurers.
