[1] | (a)The year-over-year increase in the expense associated with warranties issued in 2013 and 2012 reflected higher housing revenues in each of those years. Additionally, in 2013, we increased the warranty accrual rate per home based on our historical claims experience.
[2] | (b)Adjustments in 2013 were comprised of charges associated with water intrusion-related issues in central and southwest Florida, while in 2012, favorable warranty adjustments were partly offset by such water intrusion-related charges. In 2011, favorable warranty adjustments were partly offset by the impact of our consolidation of a previously unconsolidated joint venture.
[3] | a)These expenses are included in selling, general and administrative expenses and largely offset by contributions from subcontractors participating in the wrap-up policy.
[4] | (b)Recoveries are reflected at the time we receive funds from subcontractors and/or their insurers.
