Commitments and Contingencies Warranty We use subcontractors for nearly all aspects of home construction. Although our subcontractors are generally required to repair and replace any product or labor defects, we are, during applicable warranty periods, ultimately responsible to the homeowner for making such repairs. As such, we record warranty reserves to cover our exposure to the costs for materials and labor not expected to be covered by our subcontractors to the extent they relate to warranty-type claims. Warranty reserves are established by charging cost of sales and crediting a warranty reserve for each home delivered. The amounts charged are estimated by management to be adequate to cover expected warranty-related costs under the Companys warranty programs. Warranty reserves are recorded for warranties under our Home Builders Limited Warranty (HBLW) and our transferable structural warranty in Other Liabilities on the Companys Unaudited Condensed Consolidated Balance Sheets. The warranty reserves for the HBLW are established as a percentage of average sales price and adjusted based on historical payment patterns determined, generally, by geographic area and recent trends. Factors that are given consideration in determining the HBLW reserves include: (1) the historical range of amounts paid per average sales price on a home; (2) type and mix of amenity packages added to the home; (3) any warranty expenditures not considered to be normal and recurring; (4) timing of payments; (5) improvements in quality of construction expected to impact future warranty expenditures; and (6) conditions that may affect certain projects and require a different percentage of average sales price for those specific projects. Changes in estimates for warranties occur due to changes in the historical payment experience and differences between the actual payment pattern experienced during the period and the historical payment pattern used in our evaluation of the warranty reserve balance at the end of each quarter. Actual future warranty costs could differ from our current estimated amount. Our warranty reserves for our transferable structural warranty programs are established on a per-unit basis. While the structural warranty reserve is recorded as each house is delivered, the sufficiency of the structural warranty per unit charge and total reserve is reevaluated on an annual basis, with the assistance of an actuary, using our own historical data and trends, industry-wide historical data and trends, and other project specific factors. The reserves are also evaluated quarterly and adjusted if we encounter activity that is inconsistent with the historical experience used in the annual analysis. These reserves are subject to variability due to uncertainties regarding structural defect claims for products we build, the markets in which we build, claim settlement history, insurance and legal interpretations, among other factors. Our warranty reserve amounts are based upon historical experience and geographic location. While we believe that our warranty reserves are sufficient to cover our projected costs, there can be no assurances that historical data and trends will accurately predict our actual warranty costs. A summary of warranty activity for the three and six months ended June 30, 2020 and 2019 is as follows: Three Months Ended June 30, Six Months Ended June 30, (In thousands) 2020 2019 2020 2019 Warranty reserves, beginning of period $ 26,040 $ 25,220 $ 26,420 $ 26,459 Warranty expense on homes delivered during the period 4,242 3,641 7,663 6,481 Changes in estimates for pre-existing warranties (623) 557 (644) 735 Charges related to stucco-related claims  (a)   (a)  Settlements made during the period (3,484) (3,944) (7,264) (8,201) Warranty reserves, end of period $ 26,175 $ 25,474 $ 26,175 $ 25,474 (a) Represents charges for stucco-related repair costs, net of recoveries during the period. We have received claims related to stucco installation from homeowners in certain of our communities in our Tampa and Orlando, Florida markets and have been named as a defendant in legal proceedings initiated by certain of such homeowners. These claims primarily relate to homes built prior to 2014 which have second story elevations with frame construction. During the three month period ended June 30, 2020, we (1) incurred $0.5 million of additional stucco-related charges as a result of our on-going review of stucco-related data described below and (2) also received $0.5 million of additional recoveries for past stucco-related claims, resulting in a net charge of zero for the three and six months ended June 30, 2020. At June 30, 2020, the remaining reserve for (1) homes in our Florida communities that we have identified as needing repair but have not yet completed the repair and (2) estimated repair costs for homes in our Florida communities that we have not yet identified as needing repair but that may require repair in the future included within our warranty reserve was $4.0 million. We believe that this amount is sufficient to cover both known and estimated future repair costs as of June 30, 2020. Our remaining stucco-related reserve is gross of any recoveries. Stucco-related recoveries are recorded in the period the reimbursement is received. Our review of the stucco-related issues in our Florida communities is ongoing. Our estimate of future costs of stucco-related repairs is based on our judgment, various assumptions and internal data. Due to the degree of judgment and the potential for variability in our underlying assumptions and data, as we obtain additional information, we may revise our estimate, including to reflect additional estimated future stucco-related repairs costs, which revision could be material. We continue to investigate the extent to which we may be able to further recover a portion of our stucco repair and claims handling costs from other sources, including our direct insurers, the subcontractors involved with the construction of the homes and their insurers. As of June 30, 2020, we are unable to estimate any additional amount that we believe is probable of recovery from these sources and, as noted above, we have not recorded a receivable for recoveries nor included an estimated amount of recoveries in determining our stucco-related warranty reserve. Performance Bonds and Letters of Credit At June 30, 2020, the Company had outstanding approximately $256.0 million of completion bonds and standby letters of credit, some of which were issued to various local governmental entities that expire at various times through November 2027. Included in this total are: (1) $180.5 million of performance and maintenance bonds and $56.3 million of performance letters of credit that serve as completion bonds for land development work in progress; (2) $13.2 million of financial letters of credit, of which $12.7 million represent deposits on land and lot purchase agreements; and (3) $6.0 million of financial bonds. Land Option Contracts and Other Similar Contracts At June 30, 2020, the Company also had options and contingent purchase agreements to acquire land and developed lots with an aggregate purchase price of approximately $715.7 million. Purchase of properties under these agreements is contingent upon satisfaction of certain requirements by the Company and the sellers. Legal Matters In addition to the legal proceedings related to stucco, the Company and certain of its subsidiaries have been named as defendants in certain other legal proceedings which are incidental to our business. While management currently believes that the ultimate resolution of these other legal proceedings, individually and in the aggregate, will not have a material effect on the Companys financial position, results of operations and cash flows, such legal proceedings are subject to inherent uncertainties. The Company has recorded a liability to provide for the anticipated costs, including legal defense costs, associated with the resolution of these other legal proceedings. However, the possibility exists that the costs to resolve these legal proceedings could differ from the recorded estimates and, therefore, have a material effect on the Companys net income for the periods in which they are resolved. At June 30, 2020 and December 31, 2019, we had $1.4 million and $0.7 million reserved for legal expenses, respectively.
