The homebuilding industry is capital intensive and homebuilding requires significant up-front expenditures to acquire land and to begin development. Accordingly, we incur substantial indebtedness to finance our homebuilding activities. If internally generated funds are not sufficient, we would seek additional capital in the form of equity or debt financing from a variety of potential sources, including additional bank financing and/or securities offerings. The amount and types of indebtedness that we may incur are limited by the terms of our existing debt. In addition, the availability of borrowed funds, especially for land acquisition and construction financing, may be greatly reduced nationally, and the lending community may require increased amounts of equity to be invested in a project by borrowers in connection with both new loans and the extension of existing loans. The credit and capital markets have continued to experience significant volatility. If we are required to seek additional financing to fund our operations, the volatility in these markets may restrict our flexibility to access such financing. If we are not successful in obtaining sufficient capital to fund our planned capital and other expenditures, we may be unable to acquire land for our housing developments, thereby limiting our anticipated growth and community count. Additionally, if we cannot obtain additional financing to fund the purchase of land under our option contracts,agreements, we may incur contractual penalties and fees.

We are subject to a variety of local, state and federal statutes, ordinances, rules and regulations concerning the protection of health and the environment. The particular environmental laws that apply to any given community vary greatly according to the location of the community site, the site's environmental conditions and the present and former use of the site. Environmental laws may result in delays, may cause us to implement time consuming and expensive compliance programs and may prohibit or severely restrict development in certain environmentally sensitive regions or areas. From time to time, the United States Environmental Protection Agency (EPA) and similar federal or state agencies review homebuilders' compliance with environmental laws and may levy fines and penalties for failure to strictly comply with applicable environmental laws or impose additional requirements for future compliance as a result of past failures. Any such actions taken with respect to us may increase our costs or harm our reputation. Further, we expect that increasingly stringent requirements will be imposed on homebuilders in the future. Environmental regulations can also have an adverse impact on the availability and price of certain raw materials such as lumber. Our communities in California are especially susceptible to restrictive government regulations and environmental laws, particularly surrounding water usage due to continuing drought conditions within that region.

In addition, there is a growing concern from advocacy groups and the general public that the emissions of greenhouse gases and other human activities have caused, or will cause, significant changes in weather patterns and temperatures and the frequency and severity of natural disasters. Government mandates, standards and regulations enacted in response to these projected climate changeschange impacts could result in restrictions on land development in certain areas or increased energy, transportation, and raw material costs that may adversely affect our financial condition and results of operations.

Regulatory requirements could cause us to incur significant liabilities and operating expenses and could restrict our business activities. We are subject to local, state and federal statutes and rules regulating, among other things, certain developmental matters, building and site design, the availability of water and matters concerning the protection of health, safety and the environment. Our operating costs may be increased by governmental regulations, such as building permit allocation ordinances and impact and other fees and taxes, which may be imposed to defray the cost of providing certain governmental services and improvements. Other governmental regulations, such as building moratoriums and “no growth” or “slow growth” initiatives, which may be adopted in communities that have developed rapidly, may cause delays in new home communities or otherwise restrict our business activities, resulting in reductions in our revenues. Any delay or refusal from government agencies to grant us necessary licenses, permits and approvals could have an adverse effect on our financial condition and results of operations.

With respect to certain general liability exposures, including construction defect claims, product liability claims and related claims, assessment of claims and the related liability and reserve estimation process is highly judgmental due to the complex nature of these exposures and unique circumstances of each claim. Furthermore, once claims are asserted for construction defects, it can be difficult to determine the extent to which the assertion of these claims will expand geographically. Although we have obtained insurance for construction defect claims, such policies may not be available or adequate to cover liability for damages, the cost of repairs and/or the expense of litigation. Current and future claims may arise out of events or circumstances not covered by insurance and not subject to effective indemnification agreements with our subcontractors.

Certain of our subsidiaries have been named in class action and multi-partyWhile no current material lawsuits are pending, we may be subject to civil litigation regarding claims made by homebuyers. We are also party to putative class action lawsuits related to the inventory impairment charges we recognized during fiscal 2019. We cannot predict or determine the timing or final outcome of the currentsuch lawsuits, or the effect that any adverse determinations the lawsuits may have on us. An unfavorable determination in any of the lawsuits could result in the payment by us of substantial monetary damages that may not be covered by insurance. Further, the legal costs associated with the lawsuits and the amount of time required to be spent by management and the Board of Directors on these matters, even if we are ultimately successful, could have a material adverse effect on our business, financial condition and results of operations. In addition to expenses incurred to defend the Company in these matters, under Delaware law and our bylaws, we may have an obligation to indemnify our current and former officers and directors in relation to these matters. We have obligations to advance legal fees and expenses to directors and certain officers.

Our insurance carriers may seek to rescind or deny coverage with respect to certain of the pendingsuch lawsuits, or we may not have sufficient coverage under suchour insurance policies. If the insurance companies are successful in rescinding or denying coverage, or if we do not have sufficient coverage under our policies, our business, financial condition and results of operations could be materially adversely affected.

The costs of insuring against construction defect, product liability and director and officer claims are substantial. Increasingly in recent years, lawsuits (including class action lawsuits) have been filed against builders, asserting claims of personal injury and property damage. Our insurance may not cover all of the claims, including personal injury claims, or such coverage may become prohibitively expensive. If we are not able to obtain adequate insurance against these claims, we may experience losses that could negatively impact our financial condition and results of operations, as well as our cash flows.

Historically, builders have recovered from subcontractors and their insurance carriers a significant portion of the construction defect liabilities and costs of defense that the builders have incurred. However, insurance coverage available to subcontractors for construction defects is becoming increasingly expensive and the scope of coverage is restricted. If we cannot effectively recover from our subcontractors or their carriers, we may suffer even greater losses.

A builder's ability to recover against any available insurance policy depends upon the continued solvency and financial strength of the insurance carrier that issued the policy. Many of the states in which we build homes have lengthy statutes of limitations and/or repose applicable to claims for construction defects. To the extent that any carrier providing insurance coverage to us or our subcontractors becomes insolvent or experiences financial difficulty in the future, we may be unable to recover on those policies, thereby negatively impactimpacting our financial condition and results of operations.

Our future success depends upon our ability to attract, train and retain skilled personnel, including officers and directors. If we are unable to retain our key employees or attract, train or retain other skilled personnel in the future, it could hinder our business strategy and impose additional costs of identifying and training new individuals. Competition for qualified personnel in all of our operating markets, as well as within our corporate operations, is intense.

Adverse developments in the war on terrorism, terrorist attacks against the United States or any outbreak or escalation of hostilities between the United States andand/or any foreign power may cause disruption to the economy, our Company, our employees and our customers, which could negatively impact our financial condition and results of operations.

As part of our normal business activities, we collect and store certain confidential information, including information about employees, homebuyers, customers, vendors and suppliers. This information is entitled to protection under a number of regulatory regimes. We share some of this information with third parties who assist us with certain aspects of our business. A significant and extended disruption of or breach of security related to our computer systems and back-up systems may result in business disruption, damage our reputation and cause us to lose customers, sales and revenue, result in the unintended misappropriation of proprietary, personal and confidential information, and require us to incur significant expense to remediate or otherwise resolve these issues including financial obligations to third parties, fines, penalties, regulatory proceedings and private litigation with potentially large costs and other competitive disadvantages. While, to date, we have not had a significant cybersecurity breach or attack that had a material impact sales, which could causeon our revenuesbusiness or results of operations, there can be no assurance that our efforts to decline.maintain the security and integrity of these types of IT networks and related systems will be effective or that attempted security breaches or disruptions would not be successful or damaging.

The Company's credit rating and ratings on our senior notes and our current credit condition affect, among other things, our ability to access new capital, especially debt. Negative changes in these ratings may result in more stringent covenants and higher interest rates under the terms of any new debt. If our credit ratings are lowered or rating agencies issue adverse commentaries in the future, it could have a material adverse effect on our business, financial condition, results of operations business performance,and liquidity. In particular, a weakening of our financial condition, including a significant increase in our leverage or prospects maydecrease in our profitability or cash flows, could adversely affect our stock priceability to obtain necessary funds, result in a credit rating downgrade or change in outlook, or otherwise increase our cost of borrowing.

Our senior notes, revolving credit facilities, letter of credit facilities and certain other debt impose certain restrictions and obligations on us. Under certain of these instruments, we must comply with defined covenants that limit our ability to, among other things, incur additional indebtedness, engage in certain asset sales, make certain types of restricted payments, engage in transactions with affiliates and create liens on our assets. Failure to comply with certain of these covenants could result in an event of default under the applicable instrument. Any such event of default could negatively impact other covenants or lead to cross defaults under certain of our other debt agreements. There can be no assurance that we will be able to obtain any waivers or amendments that may become necessary in the event of a rapidly changing media environment. Adverse publicityfuture default situation without significant additional cost or negative commentaryat all.

In addition, subject to the restrictions of our existing debt instruments, we may incur additional indebtedness. If new debt is added to our current debt levels, the related risks that we now face could intensify. Our growth plans and our ability to make payments of principal or interest on, social media outletsor to refinance, our indebtedness will depend on our future operating performance and our ability to enter into additional debt and/or equity financings. If we are unable to generate sufficient cash flows in the future to service our debt, we may be required to refinance all or a portion of our existing debt, to sell assets or to obtain additional financing. We may not be able to do any of the foregoing on terms acceptable to us, if at all.

Section 382 of the Internal Revenue Code contains rules that limit the ability of a company that undergoes an “ownership change,” which is generally defined as any change in ownership of more than 50% of its common stock over a three-year period, to utilize its net operating results,loss carryforwards, tax credits and certain built-in losses or deductions, as consumers might avoidof the ownership change date, that are recognized during the five-year period after the ownership change. These rules generally operate by focusing on changes in the ownership among shareholders owning, directly or protest brands that receive bad pressindirectly, 5% or negative reviews. Negative publicitymore of the company's common stock (including changes involving a shareholder becoming a 5% shareholder) or any change in ownership arising from a new issuance of stock or share repurchases by the company.

We currently have an immaterial amount of "built-in losses" in our assets, i.e., an excess tax basis over current fair market value, which may result in tax losses as such assets are sold. Those "built-in losses" could become significant in the future if market conditions worsen and our inventory is impaired. Net operating losses and tax credits generally may be carried forward for a decrease20-year period to offset future earnings and reduce our federal income tax liability. Any net operating losses created during or after our fiscal 2019 may be carried forward indefinitely; however, the loss can only be utilized to offset 80% of taxable income generated in a tax year. Built-in losses, if and when recognized, generally will result in tax losses that may then be deducted or carried forward. However, we experienced an “ownership change” under Section 382 as of January 12, 2010. As a result of this previous “ownership change” for purposes of Section 382, our ability to use certain net operating loss carryforwards, tax credits and built-in losses or deductions in existence prior to the ownership change was limited by Section 382. We cannot predict or control the occurrence or timing of another ownership change in the future. If another ownership change were to occur, the limitations imposed by Section 382 could result in a material amount of our net operating loss carryforwards and tax credits expiring unused and, therefore, significantly impair the future value of our deferred tax assets.

We historically have experienced, and expect to continue to experience, variability in home sales and earnings on a quarterly basis. As a result of such variability, our historical performance may not be a meaningful indicator of future results. In addition, residentsOur quarterly results of communitiesoperations may continue to fluctuate in the future as a result of a variety of both national and local factors, including, among others:
