We also have a reportable segment for our financial services operations, which consistconsists principally of mortgage banking, title, and titleinsurance brokerage operations. Our Financial Services segment operates generally in the same geographic markets as our Homebuilding segments.

Our Homebuilding operations are geographically diverse within the U.S. As of December 31, 2019, we operated out of 863 active communities in 42 markets across 23 states. Sales prices of unit closings during 2019 ranged from approximately $100,000 to over $2,300,000, with 92% falling within the range of $200,000 to $750,000. The average unit selling price in 2019 was $427,000, compared with $425,000 in 2018, $395,000 in 2017, $373,000 in 2016, and $338,000 in 2015. The increase in average selling price in recent years resulted from a number of declining sales volume, new home salesfactors, including favorable market conditions and changes in the U.S. increasedgeographical and product mix of homes sold. Our average unit selling price since 2015 was also impacted by our acquisition in 2012 forJanuary 2016 of substantially all of the first time since 2005, beginningassets of JW Homes ("Wieland"), a multi-year recoverybrand geared toward move-up homebuyers.

We acquire land primarily for the construction of homes for sale. We select locations for development of homebuilding communities after completing a feasibility study, which includes, among other things, soil tests, independent environmental studies and other engineering work, an evaluation of necessary zoning and other governmental entitlements, and extensive market research that enables us to match the location with our product offering to meet the needs of consumers. We consider factors such as proximity to developed areas, population and job growth patterns, and, if applicable, estimated development costs. We frequently manage a portion of the risk of controlling our land positions through the use of land option contracts,agreements, which enable us to defer acquiring portions of properties owned by land sellers until we have determined whether and when to exercise our option. Our use of land option agreements can serve to reduce the financial risk associated with long-term land holdings. We typically acquire land with the intent to complete sales of housing units within 24 to 36 months from the date of opening a community, except in the case of certain Del Webb active adult developments and other large master-planned projects for which the completion of community build-out requires a longer time period. While our overall supply of controlled land is in excess of our short-term needs in manycertain of our markets, some of our controlled land consists of long-term positions that will not be converted to home sales in the near term. Accordingly, we remain active in our pursuit of new land investment. We may also

Land is generally purchased after it is zoned and developed, or is ready for development, for our intended use. In the normal course of business, we periodically sell land not required by our homebuilding operations. Where we develop land, we engage directly in many phases of the development process, including: land and site planning; obtaining environmental and other regulatory approvals; and constructing roads, sewers, water and drainage facilities, and community amenities, such as parks, pools, and clubhouses. We use our staff and the services of independent engineers and consultants for land development activities. Land development work is performed primarily by independent contractors and, when needed, local government authorities who construct sewer and water systems in some areas. At December 31, 2017,2019, we controlled 141,409158,262 lots, of which 89,25393,359 were owned and 52,15664,903 were under land option agreements.

We are dedicated to improving the quality and value of our homes through innovative architectural and community designs. Analyzing various qualitative and quantitative data obtained through extensive market research, we stratify our potential customers into well-defined homebuyer groups. Such stratification provides a method for understanding the business opportunities and risks across the full spectrum of consumer groups in each market. Once the needs of potential homebuyers are understood, we link our home design and community development efforts to the specific lifestyle of each consumer group. Through our understanding of each consumer group, we are ableseek to provide homes that better meet the needs and wants of each homebuyer.

Our homes targeted to first-time homebuyers tend to be smaller with product offerings geared toward lower average selling prices or higher density. Move-up homebuyers tend to place more of a premium on location and amenities. These communities typically offer larger homes at higher price points. Through our Del Webb brand, we are better able to address the needs of active adults, to whom we offer both destination communities and “in place” communities, for homebuyers who prefer to remain in their current geographic area. Many of these active adult communities are age-restricted to the age fifty-five and over homebuyer and are highly amenitized, offering a variety of features, including golf courses, recreational centers, and educational classes, to facilitate the age fifty-five and over homebuyer to maintainmaintaining an active lifestyle. In order to make the cost of these highly amenitized communities affordable to the individual homeowner, Del Webb communities tend to be larger than first-time or move-up homebuyer communities.

We believe that we are an innovator in consumer-inspired home design, and we view our design capabilities as an integral aspect of our marketing strategy. Our in-house architectural services teams, and management, supplemented by outside consultants, follow a 12-step product development process to introduce new features and technologies based on customer-validated data. Following this disciplined process results in distinctive design features, both in exterior facades and interior options and features. We typically offer a variety of house floor plans and elevations in each community, including potential options and upgrades, such as different flooring, countertop, fixture, and appliance choices, and design our base house and option packages to meet the needs of our customers as defined through rigorous market research. Energy efficiency represents an important source of value for new homes compared with existing homes and represents a key area of focus for our home designs, including high efficiency heating, ventilation, and air conditioning systems and insulation, low-emissivity windows, solar power in certain geographies, and other energy-efficient features.

The construction of our homes is conducted under the supervision of our on-site construction field managers. Substantially all of our construction work is performed by independent subcontractors under contracts that generally are priced onestablish a fixed-price basis.specific scope of work at an agreed-upon price. Using a selective process, we have teamed upaligned with what we believe are premier subcontractors and suppliers to deliver quality throughout all aspects of the house construction process. In addition, our construction field managers and customer care associates interact with our homebuyers throughout the construction process and instruct homebuyers on post-closing home maintenance.

Continuous improvement in our house construction process is a key area of focus. We seek to build superior quality homes while maintaining efficient construction operations by using standard materials and components from a variety of sources and by using industry and company-specific construction practices. We are improving our product offerings and production processes through the following programs:

The ability to consistently source qualified labor at reasonable prices remains challenging as labor supply growth has not kept pace withGenerally, the construction demand. Additionally,materials used in our operations are readily available from numerous sources. However, the cost of certain building materials, especially lumber, steel, concrete, copper, and petroleum-based materials, is influenced by changes in global commodity prices, national tariffs, and other foreign trade expenses.factors. Additionally, the ability to consistently source qualified labor at reasonable prices remains challenging as labor supply growth has not kept pace with construction demand. To protect against changes in construction costs, labor and materials costs are generally established prior to or near the time when related sales contracts are signed with customers. In addition, we leverage our size by actively negotiating for certain materials on a national or regional basis to minimize costs. We are also working to establish a more integrated

Although significant changes in market conditions have impacted our seasonal patterns in the past and could do so again, we historically experience variability in our quarterly results from operations due to the seasonal nature of the homebuilding industry. We generally experience increases in revenues and cash flow from operations during the fourth quarter based on the timing of home closings. This seasonal activity increases our working capital requirements in our third and fourth quarters to support our home production and loan origination volumes. As a result of the seasonality of our operations, our quarterly results of operations are not necessarily indicative of the results that may be expected for the full year.

Our operations are subject to extensive regulations imposed and enforced by various federal, state, and local governing authorities. These regulations are complex and include building codes, land zoning and other entitlement restrictions, health and safety regulations, labor practices, marketing and sales practices, environmental regulations, rules and regulations relating to mortgage financing and title operations, and various other laws, rules, and regulations. Collectively, these regulations have a significant impact on the site selection and development of our communities,communities; our house design and construction techniques,techniques; our relationships with customers, employees, suppliers, and suppliers / subcontractors,subcontractors; and many other aspects of our business. The applicable governing authorities frequently have broad discretion in administering these regulations, including inspections of our homes prior to closing with the customer in the majority of municipalities in which we operate. Additionally, we may experience extended timelines for receiving required approvals from municipalities or other government agencies that can delay our anticipated development and construction activities in our communities.

In originating mortgage loans, we initially use our own funds, including funds available pursuant to credit agreements with third parties, and subsequently sell such mortgage loans to third party investors in the secondary market. Substantially all of the loans we originate are sold in the secondary market within a short period of time after origination, generally within 30 days. We also sell the servicing rights for the loans we originate through fixed price servicing sales contracts to reduce the risks

The mortgage industry in the U.S. is highly competitive. We compete with other mortgage companies and financial institutions to provide attractive mortgage financing to our homebuyers. We utilize a centralized fulfillment center for our mortgage operations that performs underwriting, processing, and closing functions. We believe centralizing both the fulfillment

In originating and servicing mortgage loans, we are subject to the rules and regulations of the government-sponsored investors and other investors that purchase the loans we originate, as well as to those of other government agencies that have oversight of the government-sponsored investors or consumer lending rules in the U.S. In addition to being affected by changes in these programs, our mortgage banking business is also affected by many of the same factors that impact our homebuilding business.

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 investorsinvestor, or reimburse the investors' losses (a "make-whole" payment).investor's actual losses.

Our subsidiary title insurance companies serve as title insurance agents and underwriters in select markets by providing title insurance policies and examination and closing services to buyers of homes we sell. Historically, we have not experienced significant claims related to our title operations.

Discussion of our business and operations included in this annual report on Form 10-K should be read together with the risk factors set forth below. They describe various risks and uncertainties to which we are, or may become, subject. These risks and uncertainties, together with other factors described elsewhere in this report, have the potential to affect our business, financial condition, results of operations, cash flows, strategies, or prospects in a material and adverse manner.

We also compete with resales of existing or foreclosed homes, housing speculators, and available rental housing.

Significant judgment is required in determining our provision for income taxes and our reserves for federal, state, and local taxes. In the ordinary course of business, there may be matters for which the ultimate outcome is uncertain. Our evaluation of our tax matters is based on a number of factors, including changes inrelevant facts orand circumstances, changes inapplicable tax law, correspondence with tax authorities during the course of audits, and effective settlement of audit issues. Although we believe our approach to determining the tax treatment for such items is appropriate, no assurance can be given that the final tax authority review will not be materially different than that which is reflected in our income tax provision and related tax

We are periodically audited by various federal, state, and local authorities regarding tax matters. Our current audits are in various stages of completion; however, no outcome for a particular audit can be determined with certainty prior to the conclusion of the audit, appeal, and, in some cases, litigation process. As each audit is concluded, adjustments, if any, are recorded in our financial statements in the period determined. To provide for potential tax exposures, we consider a variety of factors, including changes inrelevant facts orand circumstances, changes inapplicable tax law, correspondence with taxing authorities, and effective settlement of audit issues. If these reserves are insufficient upon completion of an audit, there could be an adverse impact on our financial position, cash flows, and results of operations.

Although we expect all of our subcontractors, employees, officers, and directors to comply at all times with all applicable laws, rules, and regulations, there may be instances in which subcontractors or others through whom we do business engage in practices that do not comply with applicable laws, regulations, or governmental guidelines. When we learn of practices that do not comply with applicable laws or regulations, including practices relating to homes, buildings, or multifamily rental properties we build or finance, we move actively to stop the non-complying practices as soon as possible, and we have taken disciplinary action regarding subcontractors and employees of ours who were aware of non-complying practices and did not take steps to address them, including in some instances terminating their employment. However, regardless of the steps we take after we learn of practices that do not comply with applicable laws or regulations, we can in some instances be subject to fines or other governmental penalties, and our reputation can be injured, due to the practices' having taken place.

Our homebuilding and corporate headquarters are located in leased office facilities at 3350 Peachtree Road NE, Suite 150, Atlanta, Georgia 30326. Pulte Mortgage leases its primary office facilities in Englewood, Colorado. We also maintain various support functions in leased facilities in Tempe, Arizona, and Bloomfield Hills, Michigan.Arizona. Our homebuilding divisions and financial services branches lease office space in the geographic locations in which they conduct their daily operations.

Because of the nature of our homebuilding operations, significant amounts of property are held as inventory in the ordinary course. Such properties are not included in response to this Item.

We are involved in various legal and governmental proceedings incidental to our continuing business operations, many involving claims related to certain construction defects. The consequences of these matters are not presently determinable but, in our opinion, after consulting with legal counsel and taking into account insurance and reserves, the ultimate liability is not expected to 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 our estimates reflected in the recorded reserves relating to such matter, we could incur additional charges that could be significant.
