[1] | (b)Adjustments in 2014 were primarily comprised of reclassifications of estimated minimum probable recoveries to receivables and a reclassification to establish a separate accrual for a water intrusion-related inquiry from the Office of the Attorney General of the State of Florida (the “Attorney General’s Office”). These items had no impact on our consolidated statements of operations. Adjustments in 2013 were comprised of charges associated with water intrusion-related issues in central and southwest Florida. In 2012, favorable warranty adjustments were partly offset by similar water intrusion-related charges.
