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. If a loan is determined to be faulty, we either indemnify the investor for potential future losses, repurchase the loan from the investor, or reimburse the investor's actual losses. In addition, certain trustees and investors continue to attempt to collect damages based on losses from loans that originated prior to 2009. Some of our mortgage subsidiaries are currently defendants in litigation related to such claims.

CTX Mortgage Company, LLC ("CTX Mortgage") was the mortgage subsidiary of Centex and ceased originating loans in December 2009. Both CTX Mortgage and Pulte Mortgage sold certain loans originated prior to 2009 to financial institutions that were subsequently included in residential mortgage-backed securities or other securitizations issued by such financial institutions. In connection with such sales, CTX Mortgage and Pulte Mortgage have been put on notice of potential direct and / or third-party claims for indemnification arising out of litigation relating to certain of these residential mortgage-backed securities or other securitizations and, in some instances, such claims have resulted in legal proceedings against CTX Mortgage and Pulte Mortgage. We cannot yet quantify CTX Mortgage's or Pulte Mortgage's potential liability as a result of these matters. We do not believe, however, that these matters will have a material adverse impact on the results of operations, financial position, or cash flows of the Company.

Our recorded liabilities for all such claims totaled $11.9 million and $25.2 million at September 30, 2020 and December 31, 2019, respectively. The decrease in liabilities is primarily related to payments in connection with the settlement of certain previously recorded liabilities. Determining the liabilities for anticipated losses requires a significant level of management judgment. Given the unsettled litigation, changes in values of underlying collateral over time, unpredictable factors inherent in litigation, and other uncertainties regarding the ultimate resolution of these claims, actual costs could differ from our current estimates.

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 $250.7 million and $1.5 billion, respectively, at September 30, 2020 and $262.8 million and $1.4 billion, respectively, at December 31, 2019. 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. 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. We do not believe that a material amount, if any, of the letters of credit or surety bonds will be drawn.

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 litigation, 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.

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 projected 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):

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 us 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 our captive insurance subsidiaries represent self-insurance of these risks by us. A portion of 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 requires a per occurrence deductible up to an overall aggregate retention level. Beginning with the first dollar, amounts paid to satisfy insured claims generally 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 periodically 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 $652.5 million and $709.8 million at September 30, 2020 and December 31, 2019, respectively. 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 68% of the total general liability reserves at both September 30, 2020 and December 31, 2019. 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 can be volatile, 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 typically 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. We reduced general liability reserves by $59.4 million and $18.3 million during the nine months ended September 30, 2020 and 2019, respectively, as a result of changes in estimates resulting from actual claim experience being less than anticipated in previous actuarial projections. The changes in actuarial estimates were driven by changes in actual claims experience that, in turn, impacted actuarial estimates for potential future claims. These changes in actuarial estimates did not involve any changes in actuarial methodology but did impact the development of estimates for future periods, which resulted in adjustments to the IBNR portion of our recorded liabilities. Costs associated with our insurance programs are classified within selling, general, and administrative expenses. Changes in these liabilities were as follows ($000's omitted):

Estimates of anticipated recoveries of our costs under various insurance policies or from subcontractors or other third parties are recorded when recovery is considered probable. Such receivables are recorded in other assets and totaled $82.0 million and $118.4 million at September 30, 2020 and December 31, 2019, respectively. Those 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 described above, there generally exists a significant lag between our payment of claims and our reimbursements from applicable insurance carriers or third parties. In addition, disputes between homebuilders and insurance carriers or third parties over coverage positions relating to construction defect claims are common. Resolution of claims involves the exchange of significant amounts of information and frequently involves legal action. During the nine months ended September 30, 2019, we wrote off $24.0 million of insurance receivables in connection with policy settlement negotiations with certain of our carriers.

We lease certain office space and equipment for use in our operations. We recognize lease expense for these leases on a straight-line basis over the lease term and combine lease and non-lease components for all leases. Right-of-use ("ROU") assets and lease liabilities are recorded on the balance sheet for all leases with an expected term of at least one year. Some leases include one or more options to renew. The exercise of lease renewal options is generally at our discretion. The depreciable lives of ROU assets and leasehold improvements are limited to the expected lease term. Certain of our lease agreements include rental payments based on a pro-rata share of the lessor’s operating costs which are variable in nature. Our lease agreements do not contain any residual value guarantees or material restrictive covenants.

ROU assets are classified within other assets on the balance sheet, while lease liabilities are classified within accrued and other liabilities. Leases with an initial term of 12 months or less are not recorded on the balance sheet. ROU assets and lease liabilities were $73.5 million and $94.3 million at September 30, 2020, respectively, and $70.0 million and $91.4 million at December 31, 2019, respectively. During the nine months ended September 30, 2020, we recorded an additional $13.0 million of lease liabilities under operating leases and $4.0 million and $12.8 million during the three and nine months ended September 30, 2019, respectively. Payments on lease liabilities during the three and nine months ended September 30, 2020 totaled $4.8 million and $14.8 million, respectively, and $5.9 million and $17.4 million in the comparable prior year periods.

Lease expense includes costs for leases with terms in excess of one year as well as short-term leases with terms of less than one year. For the three and nine months ended September 30, 2020, our total lease expense was $9.6 million and $28.2 million, respectively, and $9.1 million and $27.0 million in the comparable prior year periods. Our total lease expense is inclusive of variable lease costs of $1.5 million and $4.9 million for the three and nine months ended September 30, 2020, respectively, and $1.7 million and $4.9 million in the comparable prior year periods, as well as short-term lease costs of $2.6 million and $6.6 million for the three and nine months ended September 30, 2020, respectively, and $2.4 million and $7.3 million in the comparable prior year periods. Sublease income was de minimis.
