Commitments and Contingencies Disclosure [Abstract] |
Commitments and contingencies | Commitments and contingencies Loan origination liabilities Our mortgage operations may be responsible for losses associated with mortgage loans originated and sold to investors in the event of errors or omissions relating to representations and warranties made by us that the loans met certain requirements, including representations as to underwriting standards, the existence of primary mortgage insurance, and the validity of certain borrower representations in connection with the loan. Determining the liabilities for anticipated losses requires a significant level of management judgment. Given the nature of these claims and the uncertainty regarding their ultimate resolution, actual costs could differ from our current estimates. Changes in these liabilities were as follows ($000's omitted):

Letters of credit and surety bonds In the normal course of business, we post letters of credit and surety bonds pursuant to certain performance-related obligations, as security for certain land option agreements, and under various insurance programs. The majority of these letters of credit and surety bonds are in support of our land development and construction obligations to various municipalities, other government agencies, and utility companies related to the construction of roads, sewers, and other infrastructure. We had outstanding letters of credit and surety bonds totaling $234.0 million and $1.2 billion, respectively, at June 30, 2017 and $219.1 million and $1.1 billion, respectively, at December 31, 2016. In the event any such letter of credit or surety bond is drawn, we would be obligated to reimburse the issuer of the letter of credit or surety bond. We do not believe that a material amount, if any, of the letters of credit or surety bonds will be drawn. Our surety bonds generally do not have stated expiration dates; rather we are released from the surety bonds as the underlying contractual performance is completed. Because significant construction and development work has been performed related to projects that have not yet received final acceptance by the respective counterparties, the aggregate amount of surety bonds outstanding is in excess of the projected cost of the remaining work to be performed. Litigation and regulatory matters We are involved in various litigation and legal claims in the normal course of our business operations, including actions brought on behalf of various classes of claimants. We are also subject to a variety of local, state, and federal laws and regulations related to land development activities, house construction standards, sales practices, mortgage lending operations, employment practices, and protection of the environment. As a result, we are subject to periodic examination or inquiry by various governmental agencies that administer these laws and regulations. We establish liabilities for legal claims and regulatory matters when such matters are both probable of occurring and any potential loss is reasonably estimable. We accrue for such matters based on the facts and circumstances specific to each matter and revise these estimates as the matters evolve. In such cases, there may exist an exposure to loss in excess of any amounts currently accrued. In view of the inherent difficulty of predicting the outcome of these legal and regulatory matters, we generally cannot predict the ultimate resolution of the pending matters, the related timing, or the eventual loss. While the outcome of such contingencies cannot be predicted with certainty, we do not believe that the resolution of such matters will have a material adverse impact on our results of operations, financial position, or cash flows. However, to the extent the liability arising from the ultimate resolution of any matter exceeds the estimates reflected in the recorded reserves relating to such matter, we could incur additional charges that could be significant. Allowance for warranties Home purchasers are provided with a limited warranty against certain building defects, including a one-year comprehensive limited warranty and coverage for certain other aspects of the home’s construction and operating systems for periods of up to and in limited instances exceeding 10 years. We estimate the costs to be incurred under these warranties and record liabilities in the amount of such costs at the time product revenue is recognized. Factors that affect our warranty liabilities include the number of homes sold, historical and anticipated rates of warranty claims, and the cost per claim. We periodically assess the adequacy of the warranty liabilities for each geographic market in which we operate and adjust the amounts as necessary. Actual warranty costs in the future could differ from the current estimates. Changes to warranty liabilities were as follows ($000’s omitted):

(a) | During the three and six months ended June 30, 2017, we recognized a charge of $12.1 million related to estimated costs to complete repairs in a closed-out community in Florida.
Self-insured risks We maintain, and require our subcontractors to maintain, general liability insurance coverage. We also maintain builders' risk, property, errors and omissions, workers compensation, and other business insurance coverage. These insurance policies protect us against a portion of the risk of loss from claims. However, we retain a significant portion of the overall risk for such claims either through policies issued by our captive insurance subsidiaries or through our own self-insured per occurrence and aggregate retentions, deductibles, and claims in excess of available insurance policy limits. Our general liability insurance includes coverage for certain construction defects. While construction defect claims can relate to a variety of circumstances, the majority of our claims relate to alleged problems with siding, plumbing, foundations and other concrete work, windows, roofing, and heating, ventilation and air conditioning systems. The availability of general liability insurance for the homebuilding industry and its subcontractors has become increasingly limited, and the insurance policies available require companies to maintain significant per occurrence and aggregate retention levels. In certain instances, we may offer our subcontractors the opportunity to purchase insurance through one of our captive insurance subsidiaries or participate in a project-specific insurance program provided by us. Policies issued by the captive insurance subsidiaries represent self-insurance of these risks by us. This self-insured exposure is limited by reinsurance policies that we purchase. General liability coverage for the homebuilding industry is complex, and our coverage varies from policy year to policy year. Our insurance coverage generally requires a per occurrence deductible up to an overall aggregate retention level. Beginning with the first dollar, amounts paid to satisfy insured claims apply to our per occurrence and aggregate retention obligations. Any amounts incurred in excess of the occurrence or aggregate retention levels are covered by insurance up to our purchased coverage levels. Our insurance policies, including the captive insurance subsidiaries' reinsurance policies, are maintained with highly-rated underwriters for whom we believe counterparty default risk is not significant. At any point in time, we are managing over 1,000 individual claims related to general liability, property, errors and omissions, workers compensation, and other business insurance coverage. We reserve for costs associated with such claims (including expected claims management expenses) on an undiscounted basis at the time revenue is recognized for each home closing and evaluate the recorded liabilities based on actuarial analyses of our historical claims. The actuarial analyses calculate estimates of the ultimate net cost of all unpaid losses, including estimates for incurred but not reported losses ("IBNR"). IBNR represents losses related to claims incurred but not yet reported plus development on reported claims. Our recorded reserves for all such claims totaled $814.8 million and $831.1 million at June 30, 2017 and December 31, 2016, respectively, the vast majority of which relates to general liability claims. The recorded reserves include loss estimates related to both (i) existing claims and related claim expenses and (ii) IBNR and related claim expenses. Liabilities related to IBNR and related claim expenses represented approximately 70% of the total general liability reserves at both June 30, 2017 and December 31, 2016. The actuarial analyses that determine the IBNR portion of reserves consider a variety of factors, including the frequency and severity of losses, which are based on our historical claims experience supplemented by industry data. The actuarial analyses of the reserves also consider historical third party recovery rates and claims management expenses. Housing market conditions have been volatile across most of our markets over the past ten years, and we believe such conditions can affect the frequency and cost of construction defect claims. Additionally, IBNR estimates comprise the majority of our liability and are subject to a high degree of uncertainty due to a variety of factors, including changes in claims reporting and resolution patterns, third party recoveries, insurance industry practices, the regulatory environment, and legal precedent. State regulations vary, but construction defect claims are reported and resolved over an extended period often exceeding ten years. Changes in the frequency and timing of reported claims and estimates of specific claim values can impact the underlying inputs and trends utilized in the actuarial analyses, which could have a material impact on the recorded reserves. Additionally, the amount of insurance coverage available for each policy period also impacts our recorded reserves. Because of the inherent uncertainty in estimating future losses and the timing of such losses related to these claims, actual costs could differ significantly from estimated costs. Adjustments to reserves are recorded in the period in which the change in estimate occurs. Costs associated with our insurance programs are classified within selling, general, and administrative expenses. Changes in these liabilities were as follows ($000's omitted):

(a) | Includes a general liability reserve reversal of $19.8 million for the three and six months ended June 30, 2017, related to the resolution of one previously reported claim.
(b) | Includes net changes in amounts expected to be recovered from our insurance carriers, which are recorded to other assets (see below).
In certain instances, we have the ability to recover a portion of our costs under various insurance policies or from subcontractors or other third parties. Estimates of such amounts are recorded when recovery is considered probable. Such receivables are recorded in other assets and totaled $261.8 million and $307.3 million at June 30, 2017 and December 31, 2016, respectively. The insurance receivables relate to costs incurred to perform corrective repairs, settle claims with customers, and other costs related to the continued progression of construction defect claims that we believe are insured. Given the complexity inherent with resolving construction defect claims in the homebuilding industry as described above, there generally exists a significant lag between our payment of claims and our reimbursements from applicable insurance carriers. In addition, disputes between homebuilders and carriers over coverage positions relating to construction defect claims are common. Resolution of claims with carriers involves the exchange of significant amounts of information and frequently involves legal action. During the six months ended June 30, 2017, we wrote-off $15.0 million of insurance receivables in conjunction with settling insurance policies with multiple carriers covering multiple years. Additionally, we are the plaintiff in litigation with certain of our insurance carriers in regard to $99.3 million of recorded insurance receivables relating to the applicability of coverage to such costs under their policies. We believe collection of these insurance receivables, including those in litigation, is probable based on the legal merits of our positions after review by legal counsel, favorable legal rulings received to date, the high credit ratings of our carriers, and our long history of collecting significant amounts of insurance reimbursements under similar insurance policies related to similar claims, including significant amounts funded by the above carriers under different policies. While the outcome of these matters cannot be predicted with certainty, we do not believe that the resolution of such matters will have a material adverse impact on our results of operations, financial position, or cash flows.
