The homebuilding industry is highly competitive for suitable land. The availability of finished and partially finished developed lots and undeveloped land for purchase that meet our internal criteria depends on a number of factors outside our control, including land availability in general, competition with other homebuilders and land buyers for desirable property, inflation in land prices, zoning, allowable housing density, and other regulatory requirements. Should suitable lots or land become less available, the number of homes we may be able to build and sell could be reduced, and the cost of land could be increased, perhaps substantially, which could adversely impact our results of operations.

Our long-term ability to build homes depends on our acquiring land suitable for residential building at reasonable prices in locations where we want to build. In the past, we experienced significant competition for suitable land as a result of land constraints in many of our markets. As competition for suitable land increases, and as available land is developed, the cost of acquiring suitable remaining land could rise, and the availability of suitable land at acceptable prices may decline. Any land shortages or any decrease in the supply of suitable land at reasonable prices could limit our ability to develop new communities or result in increased land costs. We may not be able to pass through to our customers any increased land costs, which could adversely impact our revenues, earnings, and margins.

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 certain representations and warranties made by us that the loans met certain requirements, including representations as to underwriting standards, the type of collateral, the existence of primary mortgage insurance, and the validity of certain borrower representations in connection with the loan.  We may also be required to indemnify underwriters that purchased and securitized loans originated by a former subsidiary of Centex for losses incurred by investors in those securitized loans based on similar breaches of representations and warranties.

The resolution of claims related to alleged breaches of these representations and warranties and repurchase claims could have a material adverse effect on our financial condition, cash flows and results of operations, and could exceed existing estimates and accruals. The repurchase liability we have recorded is estimated based on several factors, includingoperations. Given the level of current unresolved repurchase requests, the volume of estimated probable future repurchase requests, our ability to cure the defects identifiedongoing volatility in the repurchase requests, and the severitymortgage industry, changes in values of the estimated loss upon repurchase.  The factors referred to above are subject to change in light of market developments, the economic environment,underlying collateral over time, and other circumstances, someuncertainties regarding the ultimate resolution of which are beyondthese claims, actual costs could differ from our control.current estimates. Accordingly, there can be no assurance that such reserves will not need to be increased in the future.

A large majority of our customers finance their home purchases through mortgage loans, many through our mortgage bank. InterestWhile mortgage interest rates have increased moderately, they have been near historical lows for several years, which has made new homes more affordable. Increases in interest rates or decreases in the availability of mortgage financing however, could adversely affect the market for new homes. Potential homebuyers may be less willing or able to pay the increased monthly costs or to obtain mortgage financing. Lenders may increase the qualifications needed for mortgages or adjust their terms to address any increased credit risk. Even if potential customers do not need financing, changes in interest rates and mortgage availability could make it harder for them to sell their current homes to potential buyers who need financing. These factors could adversely affect the sales or pricing of our homes and could also reduce the volume or margins in our financial services business. Our financial services business could also be impacted to the extent we are unable to match interest rates and amounts on loans we have committed to originate through the various hedging strategies we employ. These developments have had, and may continue to have, a material adverse effect on the overall demand for new housing and thereby on the results of operations for our homebuilding business.

We also believe that the availability of FHA and VA mortgage financing is an important factor in marketing some of our homes. The FHA has and may continue to impose stricter loan qualification standards, raise minimum down payment requirements, impose higher mortgage insurance premiums and other costs, and/or limit the number of mortgages it insures. The liquidity provided by Fannie Mae and Freddie Mac to the mortgage industry is also critical to the housing market. The impact of the federal government’s conservatorship of Fannie Mae and Freddie Mac on the short-term and long-term demand for new housing remains unclear. Any limitations or restrictions on the availability of financing by these agencies could adversely affect interest rates, mortgage financing, and our sales of new homes and mortgage loans. Additionally, the availability of FHA and VA mortgage financing is an important factor in marketing some of our homes.

Mortgage interest expense and real estate taxes represent significant costs of homeownership, both of which are generally deductible for an individual’s federal and, in some cases, state income taxes. Any changes to income tax laws by the federal government or a state government to eliminate or substantially reduce these income tax deductions, as has been considered from time to time, would increase the after-tax cost of owning a home. Increases in real estate taxes by local governmental authorities also increase the cost of homeownership. Any such increases to the cost of homeownership could adversely impact the demand for and sales prices of new homes.

The U.S. housing industry in the U.S. is highly competitive. We compete primarily on the basis of location, price, quality, reputation, design, community amenities, and our customers' overall sales and homeownership experiences. We compete in each of our markets with numerous national, regional, and local homebuilders. This competition with other homebuilders could reduce the number of homes we deliver or cause us to accept reduced margins in order to maintain sales volume.

We also compete with resales of existing or foreclosed homes, housing speculators, and available rental housing. Increased competitive conditions in the residential resale or rental market in the regions where we operate could decrease demand for new homes or unfavorably impact pricing for new homes.

Our ability to utilize net operating losses (“NOLs”), built-in losses (“BILs”), and tax credit carryforwards to offset our future taxable income or income tax would be limited if we were to undergo an “ownership change” within the meaning of Section 382 of the Internal Revenue Code (the “IRC”). In general, an “ownership change” occurs whenever the percentage of the stock of a corporation owned by “5-percent shareholders” (within the meaning of Section 382 of the IRC) increases by more than 50 percentage points over the lowest percentage of the stock of such corporation owned by such “5-percent shareholders” at any time over the testing period.

An ownership change under Section 382 of the IRC would establish an annual limitation to the amount of NOLs, BILs, and tax credit carryforwards we could utilize to offset our taxable income or income tax in any single year. The application of these limitations might prevent full utilization of the deferred tax assets attributable to our NOLs, BILs, and tax credit carryforwards. We have not experienced an ownership change as defined by Section 382. To preserve our ability to utilize NOLs, BILs, and other tax benefits in the future without a Section 382 limitation, we adopted a shareholder rights plan, which is triggered upon certain transfers of our securities, and amended our by-laws to prohibit certain transfers of our securities. Our shareholder rights plan, as amended, expires June 1, 2019, unless our board of directors and shareholders approve an amendment to extend the term prior thereto. Notwithstanding the foregoing measures, there can be no assurance that we will not undergo an ownership change within the meaning of Section 382.

As a result of the merger with Centex in August 2009, ourOur ability to use certain of Centex’s pre-ownership change NOLs, BILs,Centex's federal losses and deductionscredits is limited under Section 382 of the Internal Revenue Code. The applicable Section 382 limitation is approximately $67.4 million per year for NOLs, losses realized on built-in loss assets that are sold within 60 months of the ownership change (i.e. before August 2014), and certain deductions.IRC. We do not believe that the Section 382 limitationlimitations will prevent the Companyus from using Centex's pre-ownership changeutilizing these Centex losses and credits. We do believe that full utilization of certain state NOL carryforwards and built-in losses or deductions.will be limited due to Section 382.

The value of our deferred tax assets is also dependent upon the tax rates expected to be in effect at the time taxable income is expected to be generated. A decrease in enacted corporate tax rates in our major jurisdictions, especially the U.S. federal corporate tax rate, would decrease the value of our deferred tax assets, which could be material.

We have significant intangible assets related to prior business combinations. We evaluate the recoverability of intangible assets whenever facts and circumstances indicate the carrying amount may not be recoverable. If the carrying value of intangible assets is deemed impaired, the carrying value is written down to fair value. This would result in a charge to our operating earnings. If management’s expectations of future results and cash flows decrease significantly, impairments of the remaining intangible assets may occur.

Our operations are subject to building, environmental, and other regulations imposed and enforced by various federal, state, and local governing authorities. New housing developments may also be subject to various assessments for schools, parks, streets, and other public improvements. These can cause an increase in the effective cost of our homes.

We also are subject to a variety of local, state, and federal laws and regulations concerning protection of health, safety, and the environment. The impact of environmental laws varies depending upon the prior uses of the building site or adjoining properties and may be greater in areas with less supply where undeveloped land or desirable alternatives are less available. These matters may result in delays, may cause us to incur substantial compliance, remediation and other costs, and can prohibit or severely restrict development and homebuilding activity in environmentally sensitive regions or areas. More stringent requirements could be imposed in the future on homebuilders and developers, thereby increasing the cost of compliance.

Our financial services operations are also subject to numerous federal, state, and local laws and regulations. These include eligibility requirements for participation in federal loan programs and compliance with consumer lending and similar requirements such as disclosure requirements, prohibitions against discrimination, and real estate settlement procedures. They also subject our operations to examination by applicable agencies, pursuant to which those agencies may limit our ability to

As a homebuilder, we are subject to home warranty, construction defect, and other claims arising in the ordinary course of business. We record warranty and other reserves for the homes we sell based on historical experience in our markets and our judgment of the qualitative risks associated with the types of homes built. We have, and require our subcontractors to have, general liability, property, errors and omissions, workers compensation, and other business insurance. These insurance policies protect us against a portion of our risk of loss from claims, subject to certain self-insured per occurrence and aggregate retentions, deductibles, and available policy limits. 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. We reserve for costs to cover our self-insured and deductible amounts under these policies and for any costs of claims and lawsuits based on an analysis of our historical claims, which includes an estimate of claims incurred but not yet reported. Because of the uncertainties inherent in these matters, we cannot provide assurance that our insurance coverage, our subcontractor arrangements, and our reserves will be adequate to address all our warranty and construction defect claims in the future. Contractual indemnities can be difficult to enforce, we may be responsible for applicable self-insured retentions, and some types of claims may not be covered by insurance or may exceed applicable coverage limits. Additionally, the coverage offered by and the availability of general liability insurance for construction defects are currently costly and limited. We have responded to increases in insurance costs and coverage limitations by increasing our self-insured retentions and claim reserves. There can be no assurance that coverage will not be further restricted andor become more costly. Additionally, we are exposed to counterparty default risk related to our subcontractors, and our insurance carriers, and our subcontractors’ insurance carriers.

Our homebuilding operations are located in many areas that are subject to natural disasters and severe weather. The occurrence of natural disasters or severe weather conditions can delay new home deliveries, increase costs by damaging inventories, reduce the availability of materials, and negatively impact the demand for new homes in affected areas. Furthermore, if our insurance does not fully cover business interruptions or losses resulting from these events, our earnings, liquidity, or capital resources could be adversely affected.

Inflation can have a long-term impact on us because increasing costs of land, materials, and labor may require us to increase the sales prices of homes in order to maintain satisfactory margins. However, we may not be able to raise home prices sufficiently to keep up with the rate of inflation and our margins could decrease. In addition, inflation is often accompanied by higher interest rates, which could have a negative impact on housing demand.
