PART I

Item 1. Business

Overview

BMC Stock Holdings, Inc. is one of the leading providers of diversified building products and services in the U.S. residential construction market. Our objective is to provide best-in-class customer service and value-added products to our customers, which are primarily single- and multi-family home builders and professional remodelers. Our product offerings include lumber and lumber sheet goods and an array of value-added products, including millwork, doors, windows and structural components such as engineered wood products (“EWP”), floor and roof trusses and wall panels. Our whole-house framing solution, Ready-Frame^®, which is one of our fastest growing product offerings, saves builders both time and money and improves job site safety. We also offer our customers important services, such as design, product specification, installation and installation management.

The 19 states in which we operate accounted for approximately 67% of 2018 U.S. single-family housing permits according to the U.S. Census Bureau. Our primary operating regions include the South and West regions of the United States (as defined by the U.S. Census Bureau), with a significant portion of our net sales derived from markets within Texas, California and Georgia. Given the local nature of our business, we locate our facilities in close proximity to our key customers and often co-locate multiple operations in one facility to increase customer service and efficiency.

The Company is a Delaware corporation and its common stock is listed on the Nasdaq Stock Market under the ticker symbol “BMCH.”

All references to “BMC,” “we,” “us,” “our” or the “Company” in this Annual Report on Form 10-K refer to BMC Stock Holdings, Inc. and its consolidated subsidiaries.

Our Customers

We serve a broad customer base across 45 metropolitan areas in 19 states that includes a mix of large-scale production homebuilders, custom homebuilders, multi-family builders and professional repair and remodeling contractors. Our largest 10 customers accounted for approximately 21% of our 2018 net sales, with no single customer accounting for more than 6% of our 2018 net sales. Our largest customers comprise primarily large production homebuilders, including publicly traded companies such as D.R. Horton, Inc., Hovnanian Enterprises, Inc., Lennar Corporation, PulteGroup, Inc., Toll Brothers, Inc. and TRI Pointe Group, Inc. In addition to these large production homebuilders, we also service and supply regional and local custom homebuilders. We also serve professional residential remodeling contractors and multi-family and light commercial contractors in most of our markets.

Our Products and Services

We provide a wide variety of building products and services directly to homebuilder and professional contractor customers. We offer a broad range of products sourced through a network of suppliers with whom we have strategic supplier agreements. These products are available through our distribution locations and eCommerce platform and, in most instances, are delivered to the job site. We manufacture floor trusses, roof trusses, wall panels, stairs, specialty millwork, windows and pre-hung doors. We have developed several proprietary capabilities to design, pre-cut, label and bundle lumber and lumber sheet goods into customized framing packages, which we have branded Ready-Frame^®. We also provide an extensive range of installation services and special order products.

We group our building products and services into four product categories: (i) structural components, (ii) lumber and lumber sheet goods, (iii) millwork, doors and windows, and (iv) other building products and services. For the year ended December 31, 2018, our sales of structural components and millwork, doors and windows products represented 43% of net sales. Each of these categories includes both manufactured and distributed products. Products in these categories typically carry a higher gross margin than lumber and lumber sheet goods and other building products and services, and provide us with opportunities to cross-sell other products and services. Information regarding net sales by product category for each of the last three fiscal years is set forth in Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Structural components.    Structural components are factory-built substitutes for job-site framing and include floor trusses, roof trusses, wall panels and EWP that in many cases we design and cut for each home. Roof trusses, floor trusses and wall panels are built in a factory controlled environment. Engineered floors and beams are cut to the required size and packaged for the given

2

application at many of our locations. Without structural components, builders construct these items on site, where weather and variable labor quality can negatively impact construction cost, quality and installation time.

In addition to increased efficiency and improved quality, a primary benefit of using structural components is shortening cycle time from start to completion, eliminating job-site waste and clutter and minimizing the amount of skilled labor that must be sourced for a job site.

Lumber and lumber sheet goods.    Lumber and lumber sheet goods include dimensional lumber, plywood and oriented strand board (“OSB”) products used in on-site house framing.

Millwork, doors and windows.    The millwork, doors and windows products category includes interior and exterior doors, windows, interior trim, custom millwork, moldings, stairs and stair parts, and cabinetry, among other products. We pre-hang interior and exterior doors in many of our markets, which consists of attaching hinges and door jambs to a door slab, thereby reducing on-site installation time and providing a higher quality finished door unit than those constructed on site. Selecting, designing and managing the procurement of the proper window package for performance and architectural reasons is a key service provided by our employees.

Other building products and services.    Other building products and services consist of various products, including hardware, wood boards, gypsum, insulation, roofing, siding and flooring. This category also includes design assistance and professional installation services of products spanning most of our product categories. Through our installation services program, we offer scheduling, supplier and subcontractor management, and other services to many of our customers. We also provide professional estimating, product advisory and product display services that assist homebuilders and their clients in selecting the appropriate mix of products to meet their needs.

Manufacturing

Our manufacturing facilities and related design capabilities are utilized to improve quality, cost and service to our homebuilder and repair and professional remodeling customers. We utilize specialized assembly and manufacturing technology and various design software packages in our manufacturing and assembly activities. Additionally, we have implemented, and continue to implement, automated manufacturing technology in certain markets. We manufacture and assemble products within two of our product categories: structural components and millwork, doors and windows.

Sales and Marketing

We seek to attract and retain customers through customer service, product quality, a range of product and service offerings and competitive pricing. This strategy is centered on building and maintaining strong customer relationships. We strive to add value for homebuilders through solution-based selling, improved product selection and procurement processes, lower material costs and general project coordination and support.

Our experienced sales and service professionals advise the homebuilder or contractor in areas such as opportunities for cost optimization, increased building or project efficiencies, new products and regional product preferences. The team coordinates a sequence of site deliveries with the customer. Our large delivery fleet and inventory management systems enable us to provide “just-in-time” product delivery. We believe this level of service is valued by our customers and generates customer loyalty. At January 31, 2019, we employed approximately 1,000 sales professionals.

Materials and Supplier Relationships

We purchase inventory primarily for distribution, some of which is also utilized in our manufacturing plants. The key materials we purchase include dimensional lumber, OSB, EWP, windows, doors and millwork. Our largest suppliers are national lumber and wood products producers and distributors such as Boise Cascade Company, Hampton Lumber, LP Building Products, Interfor Corporation, Norbord Inc., West Fraser Timber Co. Ltd. and Weyerhaeuser Company and building products manufacturers such as James Hardie Industries plc, JELD-WEN Holding, Inc., Masonite International Corp., Metrie Inc. and MI Windows and Doors, LLC. We believe there is sufficient supply in the marketplace to source most of our requirements without reliance on any particular supplier and that our diversity of suppliers affords us purchasing flexibility. We also work with our suppliers to ensure that we have sufficient adaptability and flexibility to service our customers’ needs as they evolve and as their markets grow. For certain customers, we institute purchasing programs on raw materials such as OSB to align portions of our procurement costs with our customer pricing commitments. We balance our lumber and OSB purchases with a mix of contract and spot market purchases to ensure consistent quantities of product necessary to fulfill customer contracts, to source products at the lowest possible cost and to minimize our exposure to the volatility of commodity lumber prices.

3

We currently source products from over 2,000 suppliers in order to reduce our dependence on any single company and to maximize purchasing leverage. For the year ended December 31, 2018, no supplier accounted for more than 10% of our total materials purchases. We believe we are one of the largest customers for many of our suppliers and therefore have significant purchasing leverage.

Competition

The lumber and building materials (“LBM”) distribution industry in the United States is highly fragmented, with a number of retailers and distributors offering a broad range of products and services. Demand for our products is largely driven by the level of activity in the U.S. residential construction market, particularly in single-family new construction, which has experienced improving demand trends influenced by job growth, consumer confidence, market demographics, levels of household formations, interest rate levels, inventories of available housing units and other external factors. According to the U.S. Census Bureau, from 2005 to 2011, single-family housing starts in the United States declined by approximately 75% to 0.43 million, which was significantly less than the 50-year average rate of approximately 1.0 million per year. Following several challenging years, single-family housing starts increased on a year-over-year basis each year from 2012 to 2018, with starts in 2016, 2017 and 2018 reaching 0.78 million, 0.85 million and 0.87 million, respectively.

We primarily compete in the professional building contractor segment of the U.S. residential new construction building products supply market (the “Pro Segment”). Our customers primarily consist of professional homebuilders and those that provide construction services to them. The principal methods of competition in the Pro Segment are developing long-term relationships with professional builders and retaining such customers by delivering a full range of high-quality products on time and offering trade credit, competitive pricing, flexibility in transaction processing, and integrated service and product packages, as well as offering value-added products and services such as structural components and installation. Our market positions in the highly competitive Pro Segment create economies of scale that allow us to supply our customers cost-effectively, which both enhances profitability and reduces the risk of losing customers to competitors. Approximately 11.6% of our sales during the year ended December 31, 2018 were to professional residential remodeling contractors. Competition in the professional remodeling segment includes other distributors, as well as home center retailers such as The Home Depot, Inc. and Lowe’s Companies, Inc.

We have and will continue to experience competition for homebuilder business. Many of our competitors are predominantly small, privately owned companies, local and regional materials distributors, single or multi-site lumberyards, and truss manufacturing and millwork operations. Many of these companies have limited access to capital and lack sophisticated IT systems and large-scale procurement capabilities. We believe we have substantial competitive advantages over these smaller competitors due to our long-standing customer relationships, local market knowledge, integrated supply chain and competitive pricing. We also face competition from large national lumber and building materials companies. For example, our largest competitors in our local markets often include one or more of 84 Lumber Co., Builders FirstSource, Inc., Carter Lumber Company and US LBM Holdings, LLC.

Employees

At January 31, 2019, we had approximately 9,500 full-time equivalent employees, approximately 230 of whom were represented by unions. We believe that we have good relations with our employees.

Seasonality and Other Factors

Our first and fourth quarters have historically been, and are generally expected to continue to be, adversely affected by weather patterns in some of our markets, causing reduced construction activity. In addition, quarterly results historically have reflected, and are expected to continue to reflect, fluctuations from period to period arising from the following factors, among others:

• the volatility of lumber prices;

• the cyclical nature of the homebuilding industry;

• general economic conditions in the markets in which we compete;

• the pricing policies of our competitors;

• the production schedules of our customers; and

• the effects of weather.

History

On December 1, 2015, Stock Building Supply Holdings, Inc. (“SBS” or “Legacy SBS”) completed a business combination with privately-held Building Materials Holding Corporation (“BMHC” or “Legacy BMHC”) in accordance with the terms of the Agreement and Plan of Merger, dated as of June 2, 2015, by and between SBS and BMHC (the “Merger Agreement”), pursuant to which BMHC merged with and into SBS (the “Merger”). As a result of the business combination, SBS survived the Merger and in connection therewith changed its name to BMC Stock Holdings, Inc.

BMHC was created in 1987 and initially operated approximately 20 lumber and building materials distribution facilities located in the West. BMHC grew primarily through acquisitions and expanded its footprint throughout the South and West regions of the United States.

SBS’s predecessor was founded as Carolina Builders Corporation in Raleigh, North Carolina in 1922 and began operating under the Stock Building Supply name in 2003. In addition, certain companies acquired by SBS were founded as early as 1822. On August 14, 2013, SBS completed its initial public offering.

Intellectual Property

We possess an array of intellectual property rights, including patents, trademarks, trade names, proprietary technology and know-how and other proprietary rights that are important to our brand and marketing strategy. In particular, we maintain registered trademarks for BMC^® and the BMC logo, Fortis^® and Artrim^®, two of our private label lines, and our Ready-Frame^® system. In addition, we maintain registered trademarks for the trade names under which certain of our local branches operate. While we do not believe our business is dependent on any one of our trademarks, we believe that our trademarks are important to the development and conduct of our business as well as the marketing of our products. We vigorously protect all of our intellectual property rights.

Regulation and Legislation

We are subject to various federal, state and local government regulations applicable to the business generally in the jurisdictions in which we operate, including laws and regulations relating to our relationships with our employees, public health and safety, work place safety, transportation, zoning, business, environmental, contractor licensing and fire codes. We strive to operate each of our distribution, manufacturing, retail and service facilities in accordance with applicable laws, codes and regulations.

Transportation and Work Place Safety. Our operations in domestic interstate commerce are subject to the regulatory jurisdiction of the Department of Transportation (“DOT”), which has broad administrative powers with respect to our transportation operations. We are subject to safety requirements governing interstate operations prescribed by the DOT. Vehicle dimensions and driver hours of service also are subject to both federal and state regulation. Our operations are also subject to the regulatory jurisdiction of the Occupational Safety and Health Administration (“OSHA”), which has broad administrative powers with respect to workplace and jobsite safety. Our operators are also subject to state and federal labor laws regulating hours worked and compensation paid.

Environmental. Our operations and properties are also subject to federal, state and local laws and regulations relating to the use, storage, handling, generation, transportation, treatment, emission, release, discharge and disposal of hazardous materials, substances and wastes and relating to the investigation and cleanup of contaminated properties, including off-site disposal locations, stormwater and other run-off and similar issues. We have not incurred material costs in the past to comply with environmental laws and regulations. However, we could be subject to material costs, liabilities or claims relating to environmental compliance in the future, especially in the event of changes in existing laws and regulations or in their interpretation or enforcement.

As current and former owners, lessees and operators of real property, we can be held liable for the investigation or remediation of contamination on or from such properties, in some circumstances regardless of whether we knew of or caused such contamination. Our current expenditures with respect to environmental investigation and remediation at our facilities are immaterial, although no assurance can be provided that more significant investigation and remediation will not be required in the future as a result of spills or releases of petroleum products or other hazardous substances or the discovery of currently unknown environmental conditions, or changes in legislation, laws, rules or regulations or their interpretation or enforcement.

To date, costs to comply with applicable laws and regulations relating to the protection of the environment and natural resources have not had a material adverse effect on our business, financial condition, operating results or cash flow. There can be no assurance that such laws and regulations will not become more stringent in the future or that we will not incur costs in the future in order to comply with such laws and regulations. We did not incur material capital expenditures for environmental controls in fiscal year 2018 and do not anticipate material capital expenditures in this regard in fiscal year 2019.

5

Business. Our suppliers are subject to various laws and regulations, including in particular laws and regulations regulating labor, forestry and the environment. We consult with our suppliers as appropriate to confirm they have determined they are in material compliance with applicable laws and regulations. Generally, our suppliers agree contractually to comply with our expectations concerning environmental, labor and health and safety matters.

Products that we import into the United States are subject to laws and regulations imposed in conjunction with such importation, including those issued and/or enforced by U.S. Customs and Border Protection. In addition, certain of our products are subject to laws and regulations relating to the importation, acquisition or sale of illegally harvested agricultural products and the emissions of hazardous materials. We work closely with our suppliers to help ensure material compliance with the applicable laws and regulations in these areas.

Item 1A.     Risk Factors

Risks Related to Our Business

The industry in which we operate is dependent upon the homebuilding industry and repair and remodeling activity, the economy, the credit markets and other important factors.

The building products supply and services industry is highly dependent on new single-family home construction, multi-family construction and repair and remodeling activity, which in turn are dependent upon a number of factors, including interest rates, consumer confidence, employment rates, wage rates, foreclosure rates, housing inventory levels, housing demand, the availability of land, local zoning and permitting processes, the availability of construction financing, the availability of qualified trade laborers and the health of the economy and mortgage markets. Unfavorable changes in demographics, credit markets, mortgage rates, consumer confidence, health care costs, housing affordability, housing inventory levels, a weakening of the national economy or of any regional or local economy in which we operate, changes in legislation and government policy and other factors beyond our control could adversely affect consumer spending, result in decreased demand for homes and adversely affect our business.

The homebuilding industry underwent a significant downturn that began in mid-2006 and began to stabilize in late 2011. The downturn in the homebuilding industry resulted in a substantial reduction in demand for our products and services, which in turn had a significant adverse effect on our business during fiscal years 2007 through 2012. The U.S. Census Bureau reported approximately 873,000 single-family housing starts for 2018, which is an increase of approximately 3% from 2017, but still well below historical averages over the past 50 years.

There is significant uncertainty regarding the timing and extent of any continued recovery in construction and repair and remodeling activity and resulting product demand levels. According to the U.S. Census Bureau, single-family housing starts decreased approximately 8% for the three months ended December 31, 2018, as compared to the prior year period. Additionally, as of October 2018, Dodge Data & Analytics (formerly McGraw-Hill) forecasted that U.S. single-family housing starts will decrease approximately 3% in 2019. If conditions in the housing industry deteriorate, we may need to take goodwill and/or asset impairment charges. Any such non-cash charges would have an adverse effect on our financial results. In addition, we may have to temporarily idle or permanently close certain facilities in under-performing regions. Any such facility closures could have a significant adverse effect on our business, financial condition, operating results and cash flows.

The positive impact of a recovery on our business may also be dampened to the extent average size of new single-family homes decreases, which could cause homebuilders to decrease spending on our products and services. According to the U.S. Census Bureau, the average square footage of a new single-family home start decreased in 2017 and 2016, as compared to the prior year, by 1% and 2%, respectively. This trend has continued through the first three quarters of 2018.

As the housing industry is dependent upon the economy as well as potential homebuyers’ access to mortgage financing and homebuilders’ access to commercial credit, constraint of the credit markets, including an increase in interest rates, could have a significant adverse effect on our business, financial condition, operating results and cash flows.

Certain of our products are commodities and fluctuations in prices of these commodities could adversely affect our operating results.

Many of the building products we distribute, including OSB, plywood, lumber and particleboard, are commodities that are widely available from other manufacturers or distributors with prices and volumes determined frequently based on participants’ perceptions of short-term supply and demand factors. A shortage of capacity or excess capacity in the industry can result in significant increases or declines in market prices for those products, often within a short period of time.

Prices of commodity products can also change as a result of national and international economic conditions, labor and freight costs, competition, market speculation, government regulation and trade policies and tariffs, as well as from periodic delays in the delivery of lumber and other products. Short-term changes in the cost of these materials, some of which are subject to significant fluctuations, are sometimes passed on to our customers but our pricing quotation periods and pricing pressure from our competitors may limit our ability to pass on such price changes. For example, we frequently enter into extended pricing commitments, which may compress our gross margins in periods of inflation. At times, the price at which we can charge our customers for any one or more products may even fall below the price at which we can purchase such products, requiring us to incur short-term losses on product sales. Excessive spikes in the market prices of certain building products, such as lumber, can also put negative pressure on our operating cash flows by requiring us to invest more in inventory. We may also be limited in our ability to pass on increases in freight costs on our products due to the price of fuel.

7

Periods of generally increasing prices provide the opportunity for higher sales and increased gross profit (subject to the extended pricing commitments described above), while generally declining price environments may result in declines in sales and profitability. In particular, low market prices for wood products over a sustained period can adversely affect our business, financial condition, operating results and cash flows, as can excessive spikes in market prices. For the year ended December 31, 2018, average composite framing lumber prices and average composite structural panel prices (a composite calculation based on index prices for OSB and plywood) as reported by Random Lengths were $460 and $481, respectively. However, there was significant volatility during the year, as the average composite framing lumber prices and average composite structural panel prices declined during the second half of 2018 from a peak of $564 and $566, respectively, during June 2018, to $335 and $365, respectively, during December 2018. If lumber or structural panel prices were to remain at or continue to decline significantly from current levels, our sales and profits could be negatively affected as compared to 2018 operating results. Our lumber and lumber sheet goods product category represented approximately 35% of net sales in 2018.

Some of our products are imported into the United States and may be subject to tariffs or import duties that may impact the price of the products and limit their availability. Furthermore, the ongoing trade dispute between the United States and Canada following the expiration of the Softwood Lumber Agreement in 2015 has led to, and could continue to lead to, increased volatility in prices of softwood lumber imported from Canada. For the year ended December 31, 2018, we imported between $285 million and $320 million of inventory, of which between $260 million and $290 million of inventory was from Canada.

Changes in our customer or product sales mix could affect our operating results.

Our operating results may vary according to the amount and type of products we sell to each of our primary customer types: single-family homebuilders, remodeling contractors, and multi-family, commercial and other contractors. We tend to realize higher gross margins on sales to remodeling contractors due to the smaller product volumes purchased by those customers, as well as the more customized nature of the projects those customers generally undertake. Gross margins on sales to single-family, multi-family commercial and other contractors can vary based on a variety of factors, including the purchase volumes of the individual customer, the mix of products sold to that customer, the size and selling price of the project being constructed and the number of upgrades added to the project before or during its construction. 

We generate significant business from the large single-family homebuilders; however, our gross margins on sales to them tend to be lower than our gross margins on sales to other market segments. A shift in our sales mix towards the larger homebuilders could negatively impact our gross margins.

In addition, we typically realize greater gross margins on more highly engineered and customized products, or ancillary products that are often purchased based on convenience and are therefore less price sensitive to our customers. For example, sales of lumber and lumber sheet goods tend to generate lower gross margins due to their commodity nature and the relatively low switching costs of sourcing those products from different suppliers. Structural components and millwork, doors and windows often generate higher gross margins relative to other products. A shift in our sales mix towards the lumber and lumber sheet goods product category could negatively impact our gross margins.

See Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” for information regarding net sales by customer type and product category for each of the last three fiscal years.

We conduct a significant portion of our business in Texas, California and Georgia, which exposes us to the homebuilding activities within the markets of these states.

We presently conduct a significant portion of our business in Texas, California and Georgia, which represented approximately 31%, 14% and 10%, respectively, of 2018 total net sales. Sales activities in these markets and in most of the other markets in which we operate have declined from time to time, particularly as a result of slow economic growth. In the last several years, many of these markets have benefited from better than average employment growth, which has aided homebuilding activities, but we cannot assure you that these conditions will continue. Local economic conditions can depend on a variety of factors, including national economic conditions, local and state budget situations and the impact of cutbacks in federal spending and employment. Additionally, our concentration in these markets increases our exposure to natural disasters and other events adversely impacting these markets. A reduction in construction and remodeling activities in these markets could negatively impact our operating results in the future. If homebuilding activity declines in one or more of these markets or the other markets in which we operate, our costs may not decline at all or at the same rate and therefore may negatively impact our operating results.

Because our operations are currently concentrated in these areas, a prolonged economic downturn or localized adverse events in the future in one or more of these areas or a particular industry that is fundamental to one of these areas, particularly within Texas, could have a material adverse effect on our business, financial condition, operating results and cash flows, and a disproportionately

8

greater impact on us than other lumber and building material companies with more diversified operations. To the extent the oil and gas industries, which can be very volatile, are negatively impacted by declining commodity prices, climate change, legislation or other factors, a result could be a reduction in employment, or other negative economic consequences, which in turn could adversely impact home sales and activities in Texas and certain of our other markets.

The loss of any of our significant customers or a reduction in the quantity of products they purchase could affect our financial health.

Our ten largest customers generated approximately 21% and 20% of our net sales for the years ended December 31, 2018 and 2017, respectively. We cannot guarantee that we will maintain or improve our relationships with these customers or that we will continue to supply these customers at historical levels.

In addition, production homebuilders and other customers may: (i) seek to purchase some of the products that we currently sell directly from manufacturers; (ii) elect to establish their own building products manufacturing and distribution facilities or (iii) give advantages to manufacturing or distribution intermediaries in which they have an economic stake. Continued consolidation among production homebuilders could also result in a loss of some of our present customers to our competitors. The loss of one or more of our significant customers or deterioration in our relations with any of them could adversely affect our business, financial condition, operating results and cash flows. Furthermore, our customers typically are not required to purchase any minimum amount of products from us. The contracts into which we have entered with most of our professional customers typically provide that we supply particular products or services for a certain period of time when and if ordered by the customer. Should our customers purchase our products in significantly lower quantities than they have in the past, such decreased purchases could have a material adverse effect on our business, financial condition, operating results and cash flows.

The building products supply and services industry is seasonal and cyclical.

Our industry is seasonal. Although weather patterns affect our operating results throughout the year, our first and fourth quarters have historically been, and are generally expected to continue to be, adversely affected by weather patterns in some of our markets, causing reduced construction activity. To the extent that hurricanes, severe storms, earthquakes, floods, fires, droughts, other natural disasters or similar events occur in the markets in which we operate, our business may be adversely affected.

The building products supply and services industry is also subject to cyclical market pressures. Quarterly results historically have reflected, and are expected to continue to reflect, fluctuations from period to period arising from the following factors, among others: the volatility of lumber prices; the cyclical nature of the homebuilding industry; general economic conditions in the markets in which we compete; the pricing policies of our competitors and the production schedules of our customers.

Our industry is highly fragmented and competitive, and increased competitive pressure may adversely affect our results.

The building products supply and services industry is highly fragmented and competitive. We face significant competition from local, regional and national building materials chains, as well as from privately-owned single site enterprises. Any of these competitors may have one or more competitive advantages over us by, among other things, (i) foreseeing the course of market development more accurately than we do, (ii) providing superior service and selling superior products, (iii) having the ability to produce or supply similar products and services at a lower cost, (iv) developing stronger relationships with our customers, (v) adapting more quickly to new technologies or evolving customer requirements than we do or (vi) developing a superior branch network in our markets. As a result, we may not be able to compete successfully with them. In addition, home center retailers and/or eCommerce retailers, which have historically concentrated their sales efforts on retail consumers and small contractors, may in the future intensify their marketing efforts to professional homebuilders. Furthermore, certain product manufacturers sell and distribute their products directly to production homebuilders. The volume of such direct sales could increase in the future. Additionally, manufacturers and specialty distributors who sell products to us may elect to sell and distribute directly to homebuilders in the future or enter into exclusive supplier arrangements with other distributors. Consolidation of production homebuilders may result in increased competition for their business. Finally, we may not be able to maintain our operating costs or product prices at a level sufficiently low for us to compete effectively. If we are unable to compete effectively, our business, financial condition, operating results and cash flows may be adversely affected.

Production homebuilders historically have exerted significant pressure on their outside suppliers to keep prices low because of their market share and ability to leverage such market share in the highly fragmented building products supply and services industry. The housing industry downturn resulted in significantly increased pricing pressures from production homebuilders and other customers. Continued consolidation among homebuilders, and changes in homebuilders’ purchasing policies or payment practices, could result in additional pricing pressure, which could adversely affect our business, financial condition, operating results and cash flows.

Some of our competitors are larger than we are and have greater financial resources. These resources may afford those competitors greater purchasing power, increased financial flexibility and more capital resources for expansion and improvement.

We are exposed to product liability, warranty, casualty, construction defect, contract, tort, employment and other claims and legal proceedings related to our business, products and services as well as services provided for us through third parties.

We are from time to time involved in product liability, warranty, casualty, construction defect, contract, tort, employment and other claims relating to our business, the products we manufacture, distribute or install, and services we provide, either directly or through third parties, that, if adversely determined, could adversely affect our business, financial condition, operating results and cash flows if we were unable to receive indemnification for such claims or were not adequately insured for such claims. We rely on manufacturers and other suppliers to provide us with many of the products we sell, distribute or install. Because we do not have direct control over the quality of such products manufactured or supplied by such third-party suppliers, we are exposed to risks relating to the quality of such products. In addition, we are exposed to potential claims arising from the conduct of our employees, homebuilders and their subcontractors, and third-party installers for which we may be liable. We and they are subject to regulatory requirements and risks applicable to general contractors, which include management of licensing, permitting and quality of our third-party installers. If we fail to manage these processes effectively or provide proper oversight of these services, we could suffer lost sales, fines and lawsuits, as well as damage to our reputation, which could adversely affect our business.

Product liability, warranty, casualty, construction defect, contract, tort, employment and other claims can be expensive to defend and can divert the attention of management and other personnel for significant periods, regardless of the ultimate outcome. Claims of this nature could also have a negative impact on customer confidence in our products and our Company. We cannot assure you that any current or future claims will not adversely affect our business, financial condition, operating results and cash flows.

We may be unable to maintain profitability or positive cash flows from operations.

We have set goals to progressively improve our profitability over time by growing our sales, increasing our gross margin and reducing our expenses as a percentage of sales. For the years ended December 31, 2018, 2017 and 2016, we had net income of $119.7 million, $57.4 million and $30.9 million, respectively, and gross margin of 24.7%, 23.6% and 24.0%, respectively. For the years ended December 31, 2018, 2017 and 2016, we generated cash from operations of $210.0 million, $93.9 million, and $106.9 million, respectively. There can be no assurance that we will achieve our profitability goals or continue to generate positive cash flow from operations. Factors that could significantly adversely affect our efforts to achieve these goals include, but are not limited to, the failure to:

• grow our revenue through organic growth or through acquisitions;

• improve our revenue mix by investing (including through acquisitions) in businesses that provide higher gross margins than we have been able to generate historically;

• achieve improvements in purchasing or maintain or increase our rebates from suppliers through our supplier consolidation and/or low-cost country initiatives;

• improve our gross margins through the utilization of improved pricing practices and technology and sourcing savings;

• maintain or reduce our overhead and support expenses as we grow;

• effectively evaluate future inventory reserves;

• collect monies owed from customers;

• maintain relationships with our significant customers; and

• integrate any businesses acquired.

Any of these failures or delays may adversely affect our ability to maintain or increase our profitability.

Our continued success will depend on our ability to retain our key employees and to attract and retain new qualified employees, while controlling our labor costs.

Our success depends in part on our ability to attract, hire, train and retain qualified managerial, operational, sales and other personnel, while at the same time controlling our labor costs. We face significant competition for these types of employees in our industry and from other industries. Labor shortages may impact our ability to hire skilled or unskilled workers with experience in carpentry, construction or fabrication. We may be unsuccessful in attracting and retaining the personnel we require to conduct and expand our operations successfully. In addition, key personnel, including sales force employees with key customer relationships, may leave us and compete against us.

Our success also depends to a significant extent on the continued service of our senior management team. Our officers and divisional vice presidents have experience in manufacturing, distribution, retail and homebuilding, and have been integral to our successful acquisition and integration of businesses to gain scale in our current markets. The loss of any member of our senior management

10

team or other experienced, senior employees or sales force employees could impair our ability to execute our business plan, cause us to lose customers and reduce our net sales, or lead to employee morale problems and/or the loss of other key employees. In any such event, our business, financial condition, operating results and cash flows could be adversely affected.

Our ability to control labor costs is subject to numerous external factors, including prevailing wage rates, the impact of legislation or regulations governing wages, regulations governing payment of workers on a “piece-work” or “piece-rate” basis, labor relations, healthcare benefits, and health and other insurance costs. In addition, we compete with other companies for many of our employees in hourly and piece-rate positions, and we invest significant resources in training and motivating them to maintain a high level of job satisfaction. These positions have historically had high turnover rates, which can lead to increased training and retention costs. If we are unable to attract or retain highly qualified employees in the future, it could adversely impact our operating results.

Product shortages, loss of key suppliers or failure to develop relationships with qualified suppliers, and our dependence on third-party suppliers and manufacturers could affect our financial health.

Our ability to offer a wide variety of products to our customers is dependent upon our ability to obtain adequate product supply from manufacturers and other suppliers. Generally, our products are obtainable from various sources and in sufficient quantities. Our ability to continue to identify and develop relationships with qualified suppliers who can satisfy our high standards for quality and our need to access products in a timely and efficient manner is a significant challenge. Our ability to access products also can be adversely affected by the financial instability of suppliers (particularly in light of continuing economic difficulties in various regions of the United States and the world), suppliers’ noncompliance with applicable laws, tariffs and import duties, supply disruptions, shipping interruptions or costs, and other factors beyond our control. The loss of, or a substantial decrease in the availability of, products from our suppliers or the loss of key supplier arrangements could adversely impact our business, financial condition, operating results and cash flows.

Although in many instances we have agreements with our suppliers, these agreements are generally terminable by either party on limited notice. Many of our suppliers also offer us favorable terms based on the volume of our purchases. If market conditions change, suppliers may stop offering us favorable terms. Failure by our suppliers to continue to supply us with products on favorable terms, commercially reasonable terms, or at all, could put pressure on our operating margins or have a material adverse effect on our business, financial condition, operating results and cash flows.

A portion of the workforces of many of our suppliers, particularly our foreign suppliers, are represented by labor unions. Workforce disputes at these suppliers may result in work stoppages or slowdowns. Such disruptions could have a material adverse effect on these suppliers ability to continue meeting our needs.

The implementation of our supply chain and technology initiatives could disrupt our operations, and these initiatives might not provide the anticipated benefits or might fail.

We have made, and we plan to continue to make, significant investments in our supply chain and technology. These initiatives are designed to streamline our operations to allow our employees to continue to provide high quality service to our customers, while simplifying customer interaction and providing our customers with a more interconnected purchasing experience. The cost and potential problems and interruptions associated with the implementation of these initiatives, including those associated with managing third-party service providers and employing new web-based tools and services, could disrupt or reduce the efficiency of our operations. In the event that we grow very rapidly, there can be no assurance that we will be able to keep up, expand or adapt our IT infrastructure to meet evolving demand on a timely basis and at a commercially reasonable cost, or at all. In addition, our improved supply chain and new or upgraded technology might not provide the anticipated benefits, it might take longer than expected to realize the anticipated benefits or the initiatives might fail altogether.

We occupy many of our facilities under long-term non-cancellable leases. If we close a facility, we are still obligated under the applicable lease. We may be unable to renew leases at the end of their terms.

Many of our facilities are located in leased premises. Many of our current leases are non-cancellable and typically have initial terms ranging from five to ten years, and most provide options to renew for specified periods of time. We believe that leases we enter into in the future will likely be long-term and non-cancellable and have similar renewal options. If we close or idle a facility, most likely we remain committed to perform our obligations under the applicable lease, which would include, among other things, payment of the base rent, insurance, taxes and other expenses on the leased property for the balance of the lease term. The inability to terminate leases when idling a facility or exiting a geographic market can have a significant adverse impact on our business, financial condition, operating results and cash flows.

In addition, at the end of the lease term and any renewal period for a facility, we may be unable to renew the lease without substantial additional cost, if at all. If we are unable to renew our facility leases, we may close or relocate a facility, which could subject us

11

to construction and other costs and risks, which in turn could have a material adverse effect on our business, financial condition, operating results and cash flows. In addition, we may not be able to secure a replacement facility in a location that is as commercially viable, including access to rail service, as the lease we are unable to renew. For example, closing a facility, even during the time of relocation, will reduce the sales that the facility would have contributed to our revenues. Additionally, the revenue and profit, if any, generated at a relocated facility may not equal the revenue and profit generated at the existing one.

We may be unable to effectively manage our inventory and working capital as our sales volume increases, which could have a material adverse effect on us.

We purchase certain materials, including lumber products, which are then sold to customers as well as used as direct production inputs for our manufactured and prefabricated products. We must maintain, and have adequate working capital to purchase, sufficient inventory to meet customer demand. Due to the lead times required by our suppliers, we order products in advance of expected sales. This requires us to forecast our sales and purchases accordingly. In periods of growth, it can be especially difficult to forecast sales accurately. We must also manage our working capital to fund our inventory purchases. In the future, if we are unable to manage effectively our inventory and working capital as we attempt to grow our business, our cash flows may be negatively affected, which could have a material adverse effect on our business, financial condition, operating results and cash flows.

The majority of our net sales are credit sales that are made primarily to customers whose ability to pay is dependent, in part, upon the economic strength of the industry and geographic areas in which they operate, and the failure to collect or timely collect monies owed from customers could adversely affect us.

The majority of our net sales volume in fiscal 2018 was facilitated through the extension of credit to our customers whose ability to pay is dependent, in part, upon the economic strength of the industry in the areas where they operate. We offer credit to customers, either through unsecured credit that is based solely upon the creditworthiness of the customer, or secured credit for materials sold for a specific job where the security lies in lien rights associated with the material going into the job. The type of credit offered depends both on the financial strength of the customer and the nature of the business in which the customer is involved. End users, resellers and other non-contractor customers generally purchase more on unsecured credit than secured credit. During the housing downturn, several of our homebuilder customers defaulted on amounts owed to us or extended their payable days as a result of their financial condition. The inability of our customers to pay off their credit lines in a timely manner, or at all, would adversely affect our business, financial condition, operating results and cash flows. Furthermore, our collections efforts with respect to non-paying or slow-paying customers could negatively impact our customer relations going forward.

Because we depend on the creditworthiness of certain of our customers, if the financial condition of our customers declines, our credit risk could increase. Significant contraction in our markets, coupled with tightened credit availability and financial institution underwriting standards, could adversely affect certain of our customers. Should one or more of our larger customers declare bankruptcy as has occurred in the past, it could adversely affect the collectability of our accounts receivable, bad debt reserves and net income.

We may not timely identify or effectively respond to consumer needs, expectations, market conditions or trends, which could adversely affect our relationship with customers, the demand for our products and services and our market share.

It is difficult to predict successfully the products and services our customers will demand. The success of our business depends in part on our ability to identify and respond promptly to changes in demographics, consumer preferences, expectations, needs and weather conditions, while also managing inventory levels. For example, an increased consumer focus on making homes energy efficient could require us to offer more energy efficient building materials and there can be no assurance that we would be able to identify appropriate suppliers on acceptable terms. Failure to identify timely or effectively respond to changing consumer preferences, expectations and building product needs could adversely affect our relationship with customers, the demand for our products and services and our market share.

Because we cannot immediately adapt our production capacity and related cost structures to rapidly changing market conditions, when demand is below our expectations, our manufacturing capacity will likely exceed our production requirements. If, during a general market upturn or an upturn in one of our geographic markets, we cannot increase our manufacturing capacity to meet product demand, we will not be able to fulfill orders in a timely manner, which could lead to order cancellations, contract breaches or indemnification obligations. This inability could materially and adversely limit our ability to improve our results. By contrast, if during an economic downturn we had excess manufacturing capacity, then our fixed costs associated with excess manufacturing capacity could have a significant adverse effect on our business, financial condition, operating results and cash flows.

12

We may be unable to successfully implement our growth strategy, which includes pursuing strategic acquisitions and opening new facilities.

Our long-term business plan provides for continued growth through strategic acquisitions and organic growth through the construction of new facilities or the expansion of existing facilities. Failure to identify and acquire suitable acquisition candidates on acceptable terms could have a material adverse effect on our growth strategy. Moreover, any future reduced operating results as we experienced during the housing downturn, our liquidity position or the requirements of the Second Amended and Restated Senior Secured Credit Agreement (the “Credit Agreement”) could prevent us from obtaining the capital required to effect new acquisitions or expansions of existing facilities. Our failure to make successful acquisitions or to build or expand facilities, including manufacturing facilities, produce saleable product or meet customer demand in a timely manner could result in damage to or loss of customer relationships, which could adversely affect our business, financial condition, operating results and cash flows.

Federal, state, local and other regulations could impose substantial costs and/or restrictions on our operations that would reduce our net income.

We are subject to various federal, state, local and other regulations, including, among other things, regulations promulgated by the DOT, work safety regulations promulgated by OSHA, employment regulations promulgated by the United States Equal Employment Opportunity Commission, regulations of the United States Department of Labor, federal and state environmental regulations, and state and local zoning restrictions, building codes and contractors’ licensing regulations. More burdensome regulatory requirements in these or other areas may increase our general and administrative costs and adversely affect our business, financial condition, operating results and cash flows. Moreover, failure to comply with the regulatory requirements applicable to our business could expose us to litigation and/or substantial penalties that could adversely affect our business, financial condition, operating results and cash flows.

Our transportation operations are subject to the regulatory jurisdiction of the DOT. The DOT has broad administrative powers with respect to our transportation operations. More restrictive limitations on vehicle weight and size, trailer length and configuration, or driver hours of service would increase our costs, which, if we are unable to pass these cost increases on to our customers, may increase our selling, general and administrative expenses and adversely affect our business, financial condition, operating results and cash flows. If we fail to comply adequately with DOT regulations or regulations become more stringent, we could experience increased inspections, regulatory authorities could take remedial action including imposing fines or shutting down our operations or we could be subject to increased audit and compliance costs. If any of these events were to occur, our business, financial condition, operating results and cash flows could be adversely affected.

In addition, the homebuilding industry is subject to various local, state and federal statutes, ordinances, codes, rules and regulations concerning zoning, building design and safety, construction, energy conservation, environmental protection and similar matters, including regulations that impose restrictive zoning and density requirements on our business or that limit the number of homes that can be built within the boundaries of a particular area. Regulatory restrictions may increase our operating expenses and limit the availability of suitable building lots for our customers, which could negatively affect our sales and earnings.

Changes in legislation and government policy may have a material adverse effect on us.

The 2016 presidential and congressional elections in the United States, as well as the 2018 midterm elections, have resulted in uncertainty with respect to, and could result in significant changes in, legislation and government policy. Specific legislative and regulatory proposals discussed during and after these elections that could have a material impact on us include, but are not limited to, modifications to international trade policy and increased regulation related to the employment of foreign workers.

Immigration reform and enforcement continues to attract significant attention in the public arena, the United States Congress and at the state and local levels. We rely in part on a seasonal workforce which requires specific types of visas to enter the United States. If new or more restrictive immigration legislation is enacted at the federal level or in states in which we do business, or if existing regulations are interpreted or enforced differently, these changes could make it more difficult or costly for us to hire United States citizens and/or legal immigrant workers. In such cases, we may incur additional costs to run our business, including to find and hire replacement workers, or may have to change the way we conduct our operations, either of which could have a material adverse effect on our business, financial condition, operating results and cash flows.

The Tax Cuts and Jobs Act of 2017 (“2017 Tax Act”) was enacted during December 2017, which, among other provisions, limits mortgage interest and state and local tax deductions, including property taxes and state income taxes, which may affect demand for new homes. The limitation on state and local tax deductions may have a greater impact in high tax states such as California, which accounted for approximately 14% of our 2018 net sales. Future changes in federal income tax laws may also affect demand for new homes. From time to time, various proposals are discussed, which, if enacted, may have an adverse effect on the homebuilding industry in general. No meaningful prediction can be made as to whether any such proposals will be enacted and,

13

if enacted, the particular form such laws would take. Because we have substantial fixed costs, relatively modest declines in our customers’ production levels could have a significant adverse effect on our business, financial condition, operating results and cash flows.

Unanticipated changes in our tax provisions, the adoption of new tax legislation or exposure to additional tax liabilities could affect our financial performance.

We are subject to income and other taxes in the United States. We are subject to ongoing tax audits in various jurisdictions. We regularly assess the likely outcome of these audits in order to determine the appropriateness of our tax provision. However, there can be no assurance that we will accurately predict the outcome of these audits, and the amounts ultimately paid upon resolution of audits could be materially different from the amounts previously included in our income tax expense and therefore could have a material impact on our tax provision, net income and cash flows. In addition, our effective tax rate in the future could be adversely affected by changes to our operating structure, changes in the valuation of deferred tax assets and liabilities, changes in tax laws, and the discovery of new information in the course of our tax return preparation.

As of December 31, 2018, we had a net deferred tax liability of $3.0 million. The carrying value of our deferred tax assets is dependent on our ability to generate future taxable income in the United States. Future changes in tax legislation could have a significant adverse effect on our tax rate or the carrying value of our deferred tax assets and liabilities. Any of these changes could affect our financial performance.

We may not be able to utilize certain of our net operating loss carryforwards, which could harm our profitability.

We have net operating loss (“NOL”) carryforwards to reduce future taxable income. As of December 31, 2018, we had NOL carryforwards to reduce future U.S. federal and state taxable income of $77.9 million and $75.1 million, respectively. Utilization of our NOL carryforwards may be subject to a substantial limitation under Section 382 of the Internal Revenue Code of 1986, as amended (“Section 382”), and comparable provisions of state tax laws, due to changes in ownership of our company that may occur in the future. Under Section 382 and comparable provisions of state tax laws, if a corporation undergoes an “ownership change,” generally defined as a greater than 50% change by value in its equity ownership over a three-year period, the corporation’s ability to carry forward its pre-change net operating losses to reduce its post-change income may be limited. We may experience ownership changes in the future as a result of future changes in our stock ownership. As a result, our ability to use our pre-change NOL carryforwards to reduce U.S. federal and state taxable income we produce in the future years may be subject to limitations, which could result in increased future tax liability to us.

We may be adversely affected by any natural or man-made disruptions to our distribution and manufacturing facilities.

We currently maintain a broad network of distribution and manufacturing facilities throughout the eastern, southern and western United States. Any widespread disruption to our facilities resulting from fire, earthquake, hurricanes and other weather-related events, an act of terrorism, labor disputes, supply chain disruptions or any other cause could damage a significant portion of our inventory and could materially impair our ability to manufacture and distribute our products to customers. We could incur significantly higher costs and longer lead times associated with distributing our products to our customers during the time that it takes for us to reopen or replace a damaged facility. In addition, any shortages of fuel or significant fuel cost increases could disrupt our ability to distribute products to our customers. Disruptions to the national or local transportation infrastructure systems may also affect our ability to keep our operations and services functioning properly. If any of these events were to occur, our business, financial condition, operating results and cash flows could be materially adversely affected.

We are subject to exposure to environmental liabilities and are subject to environmental regulation.

We are subject to various federal, state and local environmental laws, ordinances, rules and regulations, including those promulgated by the United States Environmental Protection Agency and analogous state agencies. As current and former owners, lessees and operators of real property, we can be held liable for the investigation or remediation of contamination at or from such properties, in some circumstances irrespective of whether we knew of or caused such contamination. No assurance can be provided that investigation and remediation will not be required in the future as a result of spills or releases of petroleum products or hazardous substances, the discovery of currently unknown environmental conditions, more stringent standards regarding existing contamination, or changes in legislation, laws, ordinances, rules or regulations or their interpretation or enforcement. Liabilities under these or similar regulations or more burdensome environmental regulatory requirements may increase our costs and adversely affect our business, financial condition, operating results and cash flows.

14

We are subject to health and safety laws and regulations and any failure to comply with any current or future laws or regulations could have a material adverse effect on us.

Manufacturing and building sites are inherently dangerous workplaces. Our work sites often put our employees and others in close proximity with large pieces of mechanized equipment, moving vehicles, manufacturing processes, and heavy products. As a result, we are subject to a variety of health and safety laws and regulations dealing with occupational health and safety. Unsafe work sites have the potential to increase employee turnover and raise our operating costs. Our safety record can also impact our reputation. We maintain functional groups whose primary purpose is to ensure we implement effective work procedures throughout our organization and take other steps to ensure the health and safety of our work force, but there can be no assurances these measures will be successful in preventing injuries or violations of health and safety laws and regulations. Any failure to maintain safe work sites or violations of applicable law could expose us to significant financial losses and reputational harm, as well as civil and criminal liabilities, any of which could have a material adverse effect on our business, financial condition, operating results and cash flows.

We may be adversely affected by any disruption in our information technology systems.

Our operations are dependent upon our IT systems, which encompass all of our major business functions. A substantial disruption in our IT systems for any prolonged time period (arising from, for example, system capacity limits from unexpected increases in our volume of business, outages, computer viruses, unauthorized access or delays in our service) could result in delays in receiving inventory and supplies or filling customer orders and adversely affect our customer service and relationships. Our systems might be damaged or interrupted by natural or man-made events or by computer viruses, physical or electronic break-ins, or similar disruptions affecting the global Internet. Such delays, problems or costs may have a material adverse effect on our business, financial condition, operating results and cash flows.

We are subject to cybersecurity risks that could adversely affect us, and we may incur increasing costs in an effort to minimize those risks.

Our business relies on systems, including those of third parties with whom we do business, and a website that involve the storage and transmission of customers’ and employees’ personal and proprietary information. Our systems and those of third parties with whom we do business have been, and will likely continue to be, subjected to computer viruses or other malicious codes, unauthorized access attempts and cyber-attacks that include phishing-attacks, denial-of-service attacks, ransomware, malware and hacking. Further, as our eCommerce business expands, our increased visibility and role in accepting electronic payments may put us at a greater risk of being targeted. Breach of our systems or those of third parties with whom we do business could compromise our confidential information and that of our customers or employees, impede or interrupt our business operations, and may result in other negative financial and other consequences, including remediation costs, loss of revenue, litigation, significant legal and financial exposure, loss of intellectual property and reputational damage.

To date, we have not experienced a material breach of cybersecurity. As cyber-attacks become more sophisticated generally, and as we implement changes such as giving customers greater electronic access to our systems and expanding our eCommerce, we may be required to incur significant costs to strengthen our systems from outside intrusions and/or maintain insurance coverage related to the threat of such attacks. Further, the regulatory environment related to information security and privacy is increasingly rigorous, with new and constantly changing requirements applicable to our business and those of third parties with whom we do business, and compliance with those requirements could result in additional costs and legal liabilities. Despite our efforts, we may not have the resources or technical sophistication to anticipate or prevent rapidly evolving types of cyber-attacks on our systems or those of the third parties with whom we do business. While we have implemented administrative and technical controls such as web filtering, endpoint and storage area network antivirus scanning and isolation, next-generation firewalls, a secure email gateway and mobile device administration, purchased cyber insurance coverage and taken other preventive actions to reduce the risk of cyber incidents and protect our IT, these measures, and other measures we may take in the future, can be expensive, and may be insufficient, circumvented or may become ineffective. Any of the foregoing risks and increased costs could have a material adverse effect on our business, financial condition, operating results and cash flows.

Insufficient insurance coverage could have a material adverse effect on us.

We carry insurance for general liability, auto liability and workers’ compensation exposures subject to deductibles and/or self-insured retentions that we believe to be reasonable under the circumstances, and we self-insure for employee and eligible dependent health care claims, with insurance purchased from independent carriers to cover individual claims in excess of the self-insured limits. However, our insurance program does not cover, or may not adequately cover, every potential risk associated with our business and the consequences thereof. In addition, market conditions or any significant claim or a number of claims made by or against us could cause our premiums and deductibles to increase substantially and, in some instances, our coverage may be reduced or become entirely unavailable. In the future, we may not be able to obtain meaningful coverage at reasonable rates for a variety of risks, including certain types of environmental hazards and ongoing regulatory compliance. If our insurance coverage is

15

insufficient, if we are not able to obtain sufficient coverage in the future, or if we are exposed to significant losses as a result of the risks for which we self-insure, any resulting costs or liabilities could have a material adverse effect on our business, financial condition, operating results and cash flows.

Operation on multiple ERP information systems, and the conversion from multiple systems to a single system, may negatively impact our operations.

The Company currently operates on multiple ERP systems, which we use for operations representing virtually all of our sales. Certain of our ERP systems are proprietary systems that have been highly customized by our computer programmers. We rely upon our ERP systems to manage and replenish inventory, to fill and ship customer orders on a timely basis, to coordinate our sales and distribution activities across all of our products and services and to provide information for financial reporting purposes.

Processing, consolidating and reconciling information from multiple ERP systems increases the chance of error, and we may incur significant additional costs related thereto. Inconsistencies in the information from multiple ERP systems could adversely impact our ability to manage our business efficiently and may result in heightened risk to our ability to maintain accurate books and records and comply with regulatory requirements.

Since the completion of the Merger, the Company has implemented the ERP system utilized by Legacy SBS (“the Legacy SBS ERP system”) at certain Legacy BMHC and newly acquired locations. If the remaining implementation of the Legacy SBS ERP system across Legacy BMHC and newly acquired operations is not executed successfully, this could result in business interruptions and loss of customers. If we do not complete the remaining implementation timely and successfully, we may also incur additional costs associated with this project and a delay in our ability to improve existing operations, to support future growth and to take advantage of new applications and technologies.

Such projects are inherently complex, resource intensive, and lengthy. As a result, we could experience unplanned or unforeseen issues that could adversely affect the project, our business or our results of operations, including:

• costs of implementation that materially exceed our expectations;

• diversion of management’s attention away from normal daily business operations;

• risk of incurring asset impairment charges, accelerated depreciation expense or other charges related to the early retirement of information system assets or the early termination of information system supplier agreements;

• increased demand on our operations support personnel;

• delays in the go-live of one or more of the stages of the project, resulting in additional costs or time for completion;

• errors in implementation resulting in errors in the commencement or reporting of business transactions;

• failure in the deliverables of our key partners, suppliers and implementation advisors, resulting in an inferior product, reduced business efficacy and the project not providing expected benefits;

• loss of sales or customers as a result of errors in business transactions or delays in providing products or services;

• deficiencies in the training of employees in the use of the new solution, resulting in errors in the recording of data or transactions, leading to delays in input deliveries and production impairment;

• a control failure during or post implementation, which may result in a material weakness in our internal controls over financial reporting; and

• other implementation issues leading to delays and impacts on our business.

Any of the foregoing could materially and negatively impact our business, financial condition, operating results and cash flows.

Risks Related to Our Indebtedness

Our indebtedness could adversely affect our ability to raise additional capital to fund our operations, limit our ability to react to changes in the economy or the industry, expose us to interest rate risk to the extent of our variable rate debt and prevent us from meeting our obligations under our indebtedness.

Our indebtedness includes obligations under the senior secured notes due 2024 (the “Senior Notes”) and our revolving credit facility (excluding unamortized debt issuance costs) under the Credit Agreement, as well as obligations under capital leases. As of December 31, 2018, our total debt was $365.5 million. This leverage could have important consequences, including: making it more difficult for us to satisfy our obligations with respect to our indebtedness; increasing our vulnerability to general adverse economic and industry conditions; requiring us to dedicate a portion of our cash flow from operations to payments on our indebtedness, thereby reducing the availability of our cash flow to fund working capital, capital expenditures, research and development efforts, and other general corporate purposes; increasing our vulnerability to and limiting our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate; exposing us to the risk of increased interest rates

16

as borrowings under certain of our indebtedness are subject to variable rates of interest; placing us at a competitive disadvantage compared to our competitors that have less debt; and limiting our ability to borrow additional funds.

We are substantially reliant on liquidity provided by the Credit Agreement and cash on hand to provide working capital and fund our operations. Our working capital and capital expenditure requirements are likely to grow as the housing market improves and we execute our strategic growth plan. Economic and credit market conditions, the performance of the homebuilding industry, and our financial performance, as well as other factors, may constrain our financing abilities. Our ability to secure additional financing, if available, and to satisfy our financial obligations under indebtedness outstanding from time to time will depend upon our future operating performance, the availability of credit, economic conditions and financial, business and other factors, many of which are beyond our control.

We may be unable to secure additional financing or financing on favorable terms or our operating cash flow may be insufficient to satisfy our financial obligations under our outstanding indebtedness. If additional funds are raised through the issuance of additional equity or convertible debt securities, our stockholders may experience significant dilution. We may also incur additional indebtedness in the future, including collateralized debt, subject to the restrictions contained in the Credit Agreement and indenture governing the Senior Notes (the “Indenture”). If new debt is added to our current debt levels, the related risks that we now face could intensify.

The Credit Agreement and Indenture contain various covenants that could limit our ability to operate our business.

The Credit Agreement and Indenture place limitations on our ability and the ability of our subsidiaries to, among other things, incur debt, create other liens on its assets, make investments, sell assets, pay dividends, undertake transactions with affiliates, enter into merger transactions and enter into unrelated businesses. The Credit Agreement also contains a financial covenant requiring us and our subsidiaries to maintain a Fixed Charge Coverage Ratio, as defined therein, of at least 1.00:1.00 at the end of any fiscal quarter during the period from the date that Excess Availability, as defined therein, under the Credit Agreement is less than or equal to the greater of (1) $33.3 million and (2) 10.0% of the Line Cap under the Credit Agreement, as defined therein, until the date that Excess Availability has been greater than the greater of (i) $33.3 million and (ii) 10.0% of the Line Cap for a period of at least 30 consecutive days. The Credit Agreement and Indenture also contain various customary representations and warranties, financial and collateral reporting requirements and other affirmative and negative covenants. Amounts owed under the Credit Agreement and Indenture may be accelerated and the lenders may exercise other remedies available to them upon the occurrence of various events of default set forth in the Credit Agreement and Indenture, including the failure to make principal or interest payments when due, breaches of covenants, representations and warranties set forth in the Credit Agreement and Indenture and defaults under other debt obligations. Acceleration of amounts owed under the Credit Agreement or the Indenture, or the exercise of other remedies available to holders of our debt, could materially and negatively impact our business, financial condition, operating results and cash flows.

Risks Related to Ownership of Our Common Stock

The price of our common stock may fluctuate significantly.

Volatility in the market price of our common stock may prevent you from being able to sell your shares of our common stock at or above the price you paid for them. The market price for our common stock could fluctuate significantly for various reasons, including but not limited to:

• our operating and financial performance and prospects;

• our quarterly or annual earnings or those of other companies in our industry;

• the public’s reaction to our press releases, our other public announcements and our filings with the SEC;

• changes in, or failure to meet, earnings estimates or recommendations by research analysts who track our common stock or the stock of other companies in our industry;

• changes in the frequency of coverage or the failure of research analysts to cover, or downgrades in analyst recommendations regarding, our common stock;

• general economic, industry and market conditions;

• strategic actions by us, our customers or our competitors, such as acquisitions or restructurings;

• sales of common stock by us or members of our management team;

• the granting or exercise of employee stock options or other equity compensation;

• volume of trading in our common stock; and

• the impact of the factors described elsewhere in Item 1A. “Risk Factors.”

17

In addition, in recent years, the stock market has regularly experienced significant price and volume fluctuations. This volatility has had a significant impact on the market price of securities issued by many companies, including companies in our industry. The changes have at times occurred without regard to the operating performance of the affected companies. Hence, the price of our common stock could fluctuate based upon factors that have little or nothing to do with us and these fluctuations could materially impact our share price.

We do not currently intend to pay dividends on our common stock.

We do not anticipate paying any cash dividends on our common stock for the foreseeable future. In addition, our existing indebtedness restricts, and we anticipate our future indebtedness may restrict, our ability to pay dividends. Any determination to pay dividends in the future will be at the discretion of our Board and will depend upon many factors, including our financial condition, operating results, projections, cash flows, earnings, legal requirements, restrictions in our indebtedness and agreements governing any other indebtedness we may enter into and other factors that our Board deems relevant. Accordingly, holders of our common stock may need to sell their shares to realize a return on their investment, and may not be able to sell their shares at or above the price paid for them.

Our future operating results may fluctuate significantly and our current operating results may not be a good indication of our future performance. Fluctuations in our financial results could affect our stock price in the future.

Our revenues and operating results have historically varied from period-to-period and we expect that they will continue to do so as a result of a number of factors, many of which are outside of our control. Any volatility in our financial results may make it more difficult for us to raise capital in the future or pursue acquisitions that involve issuances of our stock. Our operating results for prior periods may not be effective predictors of future performance.

Factors associated with our industry, the operation of our business and the markets for our products and services may cause our quarterly financial results to fluctuate, including:

• the seasonal and cyclical nature of the homebuilding industry;

• the highly competitive nature of our industry;

• the volatility of prices, availability and affordability of raw materials, including lumber, wood products and other building products;

• shortages of skilled and technical labor, increased labor costs and labor disruptions;

• the production schedules of our customers;

• general economic conditions, including but not limited to housing starts, repair and remodeling activity and commercial construction, inventory levels of new and existing homes for sale, foreclosure rates, interest rates, unemployment rates, relative currency values, mortgage availability and pricing, as well as other consumer financing mechanisms, that ultimately affect demand for our products;

• actions of suppliers, customers and competitors, including merger and acquisition activities, plant closures and financial failures;

• litigation, claims and investigations involving us;

• the financial condition and creditworthiness of our customers;

• cost of compliance with government laws and regulations;

• weather patterns; and

• severe weather phenomena such as drought, hurricanes, tornadoes and fire.

Any one of the factors above or the cumulative effect of some of the factors referred to above may result in significant fluctuations in our financial and other operating results, including fluctuations in our key metrics. The variability and unpredictability could result in our failing to meet our internal operating plan or the expectations of securities analysts or investors for any period. This volatility could cause the market price of our shares to fall substantially and we could face costly lawsuits, including securities class action suits.

Certain provisions of our organizational documents and other contractual provisions may make it difficult for stockholders to change the composition of our Board of Directors and may discourage hostile takeover attempts.

Certain provisions of our amended and restated certificate of incorporation (the “Charter”) and amended and restated bylaws may have the effect of delaying or preventing changes in control if our Board determines that such changes in control are not in the best interests of us and our stockholders. The provisions in our amended and restated certificate of incorporation and amended and restated bylaws include, among other things, the following:

• a classified Board with three-year staggered terms;

18

• the ability of our Board, without stockholder approval, to issue shares of preferred stock and to determine the price and other terms, including preferences and voting rights, of those shares without stockholder approval;

• stockholder action can only be taken at a special or regular meeting and not by written consent;

• advance notice procedures for nominating candidates to our Board or presenting matters at stockholder meetings;

• removal of directors only for cause;

• allowing only our Board to fill vacancies on our Board; and

• super-majority voting requirements to amend our amended and restated bylaws and certain provisions of the Charter.

Our Charter opts us out of being subject to Section 203 of the General Corporation Law of the State of Delaware (the “DGCL”), an anti-takeover law. In general, Section 203 of the DGCL prohibits a publicly held Delaware corporation from engaging in a business combination, such as a merger, with a person or group owning 15% or more of the corporation’s voting stock for a period of three years following the date the person became an interested stockholder, unless (with certain exceptions) the business combination or the transaction in which the person became an interested stockholder is approved in a prescribed manner. However, our Charter contains anti-takeover provisions that are substantially similar in effect to Section 203 of the DGCL. The anti-takeover provisions in the Charter prohibit us from engaging in a business combination, such as a merger, with a person or group owning 15% or more of our voting stock for a period of three years following the date the person became an interested stockholder, unless (with certain exceptions) the business combination or the transaction in which the person became an interested stockholder is approved in a prescribed manner. The Charter includes specified exceptions from anti-takeover provisions, which provide that (i) in certain circumstances (as described below), Davidson Kempner Capital Management LP, The Gores Group, LLC and their respective affiliates or associates (the “Grandfathered Stockholders”), and (ii) any person who would otherwise be an interested stockholder because of a transfer, assignment, conveyance, hypothecation, encumbrance or other disposition of 5% or more of our outstanding voting stock by any Grandfathered Stockholder to such person will be excluded from the “interested stockholder” definition in the Charter. From and after the third anniversary of the closing date of the Merger, each Grandfathered Stockholder is permitted to continue owning its respective ownership amount that it owns, together with its affiliates and associates, on such anniversary and will not be deemed an interested stockholder unless such Grandfathered Stockholder’s ownership level later exceeds such ownership amount of our outstanding voting stock. Moreover, each Grandfathered Stockholder, together with its affiliates and associates, may reduce its ownership amount at any time from and after the third anniversary of the effective time of the Merger; provided that, if such Grandfathered Stockholder reduces its ownership amount below the ownership amount of such Grandfathered Stockholder that exists on the third anniversary of the effective time of the Merger, such Grandfathered Stockholder may not increase its ownership amount above such reduced amount; provided, further, that if such Grandfathered Stockholder reduces its ownership amount below 15% of our outstanding voting stock after the third anniversary of the effective time of the Merger, such Grandfathered Stockholder may own any amount of voting stock below 15% of our outstanding voting stock, in the case of each of the foregoing provisos, without being deemed an interested stockholder.

While these provisions have the effect of encouraging persons seeking to acquire control of us to negotiate with our Board, they could enable the Board to hinder or frustrate a transaction that some, or a majority, of the stockholders might believe to be in their best interests and, in that case, may prevent or discourage attempts to remove and replace incumbent directors.

These provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our Board, which is responsible for appointing the members of our management.

Failure to maintain effective internal controls in accordance with Section 404 of the Sarbanes-Oxley Act could have a material adverse effect on us and our stock price.

A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud will be detected. Therefore, our internal control over financial reporting will not prevent or detect all errors and all fraud.

Ensuring that the Company has adequate internal financial and accounting controls and procedures in place to produce accurate financial statements on a timely basis is a costly and time-consuming effort that needs to be reevaluated frequently. Implementing appropriate changes to the internal controls of the Company may take a significant period of time to complete, may distract directors, officers and employees, and may entail substantial costs in order to modify existing accounting systems.

Additionally, the Company may experience material weaknesses or significant deficiencies in its internal control over financial reporting in the future. Any failure to maintain internal control over financial reporting could severely inhibit the Company’s ability to accurately report its cash flows, results of operations or financial condition. If the Company is unable to conclude that its internal control over financial reporting is effective, or if its independent registered public accounting firm determines the Company has

19

a material weakness or significant deficiency in its internal control over financial reporting, the Company could lose investor confidence in the accuracy and completeness of its financial reports, the market price of its common stock could decline and the Company could be subject to sanctions or investigations by Nasdaq, the SEC or other regulatory authorities. Failure to remedy any material weakness in the Company’s internal control over financial reporting, or to implement or maintain other effective control systems required of public companies, could also restrict its future access to the capital markets and negatively impact the price and trading market for our common stock.

Our Charter includes an exclusive forum clause, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us.

Our Charter provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will be the sole and exclusive forum for (i) any derivative action brought on behalf of the Company, (ii) any action asserting a claim of breach of a fiduciary duty owned by any director, officer or other employee of the Company to the Company or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the DGCL, our Charter or our bylaws or (iv) any action asserting a claim governed by the internal affairs doctrine. Any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock is deemed to have notice of and consented to the foregoing provisions. The exclusive forum clause may limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us. It is also possible that, notwithstanding such exclusive forum clause, a court could rule that such a provision is inapplicable or unenforceable.

We are a holding company and depend on the cash flow of our subsidiaries.

We are a holding company with no material assets other than the equity interests of our subsidiaries. Our subsidiaries conduct substantially all of our operations and own substantially all of our assets. Consequently, our cash flow and our ability to meet our obligations and pay any future dividends to our stockholders depends upon the cash flow of our subsidiaries and their ability to make payments, directly or indirectly, to us in the form of dividends, distributions and other payments. Any inability on the part of our subsidiaries to make payments to us could have a material adverse effect on our business, financial condition and results of operations.

Item 1B. Unresolved Staff Comments

Item 2. Properties

We have a broad network of distribution and manufacturing operations across 150 facilities in 19 states throughout the eastern, southern and western United States. These branches are supported from our headquarters in Raleigh, North Carolina. Many of our operations are co-located within a single facility: we have 106 distribution operations, 51 millwork fabrication operations and 52 structural component fabrication operations.

Distribution facilities generally include five to 25 acres of outside storage, a 30,000 to 60,000 square foot warehouse, office and product display space, and 15,000 to 30,000 square feet of covered storage. The outside area provides space for lumber storage and a staging area for delivery while the warehouse stores millwork, doors and windows. The distribution facilities are usually located in industrial areas with low cost real estate and easy access to freeways to maximize distribution efficiency and convenience. In most markets, at least one of the distribution facilities is situated on a rail line to facilitate the procurement of dimensional lumber in rail car quantities and minimize our cost of goods.

Our fabrication operations produce roof and floor trusses, wall panels, pre-cut engineered wood, stairs, windows, pre-hung interior and exterior doors and custom millwork. In most cases, they are located on the same premises as our distribution facilities, which facilitates the efficient distribution of product to customers. Millwork fabrication operations typically vary in size from 5,000 to 50,000 square feet of warehouse space to accommodate fabrication lines and the storage of base components and finished goods. Structural component fabrication operations vary in size from 20,000 to 50,000 square feet with five to 25 acres of outside storage for lumber and for finished goods.

We lease 97 facilities, including our corporate and branch support offices, and own 53 facilities. Many of our leases are non-cancellable and typically have an initial operating lease term of five to ten years and most provide options to renew for specified periods of time. A majority of our leases provide for fixed annual rentals. Certain of our leases include provisions for escalating rent, as an example, based on changes in the consumer price index. Most of the leases require us to pay taxes, insurance and maintenance expenses associated with the properties.

Item 3.    Legal Proceedings

We are currently involved in various claims, legal proceedings and lawsuits incidental to the conduct of our business in the ordinary course. We are a defendant in various pending lawsuits, legal proceedings and claims arising from assertions of alleged product liability, warranty, casualty, construction defect, contract, tort, employment and other claims. We carry insurance in such amounts in excess of our self-insurance retentions and/or deductibles as we believe to be reasonable under the circumstances although insurance may or may not cover any or all of our liabilities in respect of claims and lawsuits. We do not believe that the ultimate resolution of these matters will have a material adverse effect on our consolidated financial position, cash flows or operating results.

Item 4.    Mine Safety Disclosures

PART II

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Market Information for Common Stock

Our common stock is traded on the Nasdaq Stock Market under the symbol “BMCH”.

Holders of Record

As of January 31, 2019, there were approximately 25 stockholders of record of our common stock. Because many of our shares of common stock are held by brokers and other institutions on behalf of stockholders, we are unable to estimate the total number of beneficial owners represented by these record holders.

Dividend Policy

We do not plan to pay a regular dividend on our common stock. The declaration and payment of all future dividends, if any, will be at the discretion of our Board and will depend upon our financial condition, earnings, contractual conditions, restrictions imposed by the Credit Agreement and Indenture or the agreements governing any indebtedness we may incur in the future, applicable laws and other factors that our Board may deem relevant.

Securities Authorized for Issuance Under Equity Compensation Plans

For information on securities authorized for issuance under our equity compensation plans, see Item 12. “Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters.”

Issuer Purchases of Equity Securities

During November 2018, the Company’s board of directors authorized a new $75.0 million share repurchase program. Repurchases may be made at management’s discretion from time to time on the open market, subject to applicable laws, or through privately negotiated transactions. The repurchase program will expire on November 20, 2019 or may be suspended or discontinued at any time.

The following table presents our purchases of common stock during the three months ended December 31, 2018:

Item 6.    Selected Financial Data

On December 1, 2015, BMHC and SBS completed the Merger. As the Merger constituted a reverse acquisition for accounting purposes under generally accepted accounting principles in the United States, the historical financial statements of the Company reflect only the operations and financial condition of BMHC. The operating results of SBS are reported as part of the Company beginning on the closing date of the Merger. The selected consolidated financial data as of December 31, 2018 and 2017 and for the years ended December 31, 2018, 2017 and 2016 have been derived from our audited consolidated financial statements included as Item 8 of this Annual Report on Form 10-K. Selected consolidated financial data as of December 31, 2016, 2015 and 2014 and for the years ended December 31, 2015 and 2014 have been derived from our audited consolidated financial statements, which are not included herein.

The following data should be read in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” contained in Item 7 of this Annual Report on Form 10-K and with our consolidated financial statements and related notes included as Item 8 of this Annual Report on Form 10-K:

Item 7.    Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis should be read in conjunction with Item 6. “Selected Financial Data” and our consolidated financial statements and the related notes to those statements included in Item 8. “Financial Statements and Supplementary Data.” The following discussion contains, in addition to historical information, forward-looking statements that involve risks, uncertainties and assumptions. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of many factors, including those set forth under the heading Item 1A. “Risk Factors” and elsewhere in this Annual Report on Form 10-K.

Overview

We are one of the leading providers of diversified building products and services in the U.S. residential construction market. Our objective is to provide best-in-class customer service and value-added products to our customers, which are primarily single- and multi-family home builders and professional remodelers. Our product offerings include lumber and lumber sheet goods and an array of value-added products including millwork, doors, windows and structural components such as EWP, floor and roof trusses and wall panels. Our whole-house framing solution, Ready-Frame^®, which is one of our fastest growing product offerings, saves builders both time and money and improves job site safety. We also offer our customers important services such as design, product specification, installation and installation management.

As part of our initiatives to execute our strategic plan, including growing our value-added product and service offerings and expanding our presence in the professional remodeling space, we plan to continue expanding our business through organic and acquisitive means. The 19 states in which we operate accounted for approximately 67% of 2018 U.S. single-family housing permits according to the U.S. Census Bureau. In these 19 states, we operate in 45 metropolitan areas, which accounted for approximately half of the permits issued in those states, according to the U.S. Census Bureau, providing significant opportunity for growth.

Our net sales for the year ended December 31, 2018increased9.4% compared to the year ended December 31, 2017. We estimate net sales increased 5.0% from higher selling prices of lumber and lumber sheet goods, 2.1% from the net impact of the acquisitions of W.E. Shone Co. (“Shone Lumber”), Texas Plywood & Lumber Company, Inc. (“TexPly”) and Code Plus Components, LLC (“Code Plus”), partially offset by the disposition of the Company’s Coleman Floor business (“Coleman Floor”), 1.9% from other organic growth and 0.4% from an additional selling day. Our gross margin was 24.7% for the year ended December 31, 2018 compared to 23.6% for the prior year period. We recorded income from operations of $170.3 million during the year ended December 31, 2018, compared with $101.2 million during the year ended December 31, 2017. See further discussion in “-Operating Results” below.

Factors Affecting Our Operating Results

Our operating results and financial performance are influenced by a variety of factors, including, among others, acquisitions and dispositions, conditions in the housing market and economic conditions generally, changes in the cost of the products we sell (particularly commodity products), pricing policies of our competitors, production schedules of our customers and seasonality. Some of the more important factors are briefly discussed below.

Acquisitions and disposition

On November 1, 2018, the Company completed the sale of substantially all of the assets and certain liabilities of Coleman Floor for a preliminary sale price of $7.8 million, subject to certain customary post-closing adjustments.

On March 1, 2018, the Company completed the acquisition of Shone Lumber, a supplier of building materials in the state of Delaware, for a preliminary purchase price of $22.4 million, subject to a holdback.

On April 3, 2017, the Company completed the acquisition of TexPly, a supplier of production millwork and doors in the Dallas-Fort Worth area, for a purchase price of $31.7 million.

On March 27, 2017, the Company completed the acquisition of Code Plus, a truss manufacturer located in Martinsburg, West Virginia serving the Washington DC market, for a purchase price of $7.1 million.

Net sales increased by approximately $69.1 million for the year ended December 31, 2018 as a result of the acquisitions of Shone Lumber, TexPly and Code Plus, net of the disposition of Coleman Floor. Net sales increased by approximately $54.3 million for the year ended December 31, 2017 as a result of the acquisitions of TexPly and Code Plus.

See Note 3 to the consolidated financial statements included in Item 8 of this Annual Report on Form 10-K for further discussion of our acquisitions and disposition.

Conditions in the housing and construction market

The building products supply and services industry is highly dependent on new single-family home and multi-family construction and repair and remodeling activity, which in turn are dependent upon a number of factors, including, among other things, interest rates, consumer confidence, employment rates, wage rates, foreclosure rates, housing inventory levels, housing demand, the availability of land, local zoning and permitting processes, the availability of construction financing, the availability of qualified trade laborers, the health of the economy and mortgage markets and the availability of personal income tax deductions related to home ownership, some of which were limited by the 2017 Tax Act. According to the U.S. Census Bureau, single-family housing starts in the South and West regions of the United States, which are our primary operating regions, were 0.60 million, 0.66 million and 0.69 million in 2016, 2017 and 2018, respectively.

As of October 2018, Dodge Data & Analytics (formerly McGraw-Hill) forecasted that U.S. single-family housing starts will decrease approximately 3% in 2019. Additionally, the S&P Corelogic Case-Shiller Home Price Index (the "Home Price Index"), a leading measure of pricing for the U.S. residential housing market, has increased at a 6.3% compound annual growth rate from January 2012 to December 2018. The Home Price Index reached its highest levels ever during September 2018 before decreasing 0.2% during the three months ended December 31, 2018.

According to the U.S. Census Bureau, multi-family housing starts in the United States reached a low of 0.11 million in 2009, but reached levels of 0.39 million, 0.35 million and 0.37 million in 2016, 2017 and 2018, respectively. While this end market has receded since 2016, the multi-family space represents a significant opportunity for us to capture additional market share and provide value-added solutions.

The professional remodeling space, when compared to new home construction, tends to be less price sensitive and more resilient to broader economic conditions. As of September 2018, the Home Improvement Research Institute estimated 2018 and 2019 U.S. sales of home maintenance, repair and improvement products to the professional market would reach approximately $122 billion and $130 billion, respectively, compared to sales of approximately $102 billion and $111 billion in 2016 and 2017, respectively. Several factors, including the overall age of the U.S. housing stock, rising home prices, availability of consumer capital at interest rates that remain relatively low historically and focus on energy efficiency may drive long-term growth in repair and remodeling expenditures.

Overall economic conditions in the markets where we operate

Economic changes both nationally and locally in our markets impact our financial performance. Unfavorable changes in demographics, credit markets, consumer confidence, health care costs, housing affordability, interest rates, housing inventory levels, a weakening of the national economy or of any regional or local economy in which we operate and other factors beyond our control could adversely affect consumer spending, result in decreased demand for homes and adversely affect our business. We believe continued strong employment levels, access to financing and strong consumer confidence will be necessary to increase household formation rates. We believe improved household formation rates in turn will increase demand for housing and stimulate new construction.

Commodity nature of our products

Many of the building products we distribute, including lumber, OSB, plywood and particleboard, are commodities that are widely available from other manufacturers or distributors with prices and volumes determined frequently based on participants’ perceptions of short-term supply and demand factors.

The following table reflects changes in the average composite framing lumber prices (per thousand board feet) and average composite structural panel prices (per thousand square feet). These prices represent transactions between manufacturers and their customers as reported by Random Lengths and may differ in magnitude or timing from the actual selling prices or cost of goods reported in our operating results. The average composite structural panel prices are based on index prices for OSB and plywood.

26

	Year Ended December 31,
	2018 Versus 2017		2018 Average Price		2017 Versus 2016		2017 Average Price		2016 Versus 2015		2016 Average Price
Framing lumber prices	11	%	$	460	19	%	$	413	5	%	$	346
Structural panel prices	10	%	$	481	18	%	$	437	1	%	$	370

Periods of increasing prices provide the opportunity for higher sales and increased gross profit, while periods of declining prices may result in declines in sales and profitability. In particular, low market prices for wood products over a sustained period can adversely affect our financial condition, operating results and cash flows, as can excessive spikes in market prices. The impact of commodity price changes on our operating results is partially dependent on pricing commitments with our customers. For example, the highest average quarterly composite framing lumber prices and composite structural panel prices reported by Random Lengths during 2018 occurred during the three months ended June 30, 2018, while the Company’s highest quarterly average selling price of lumber and lumber sheet goods occurred during the three months ended September 30, 2018.

While the average prices noted above saw significant increase in recent years, there was significant volatility during 2018, as the average composite framing lumber prices and average composite structural panel prices declined during the second half of the year from a peak of $564 and $566, respectively, during June 2018, to $335 and $365, respectively, during December 2018. If lumber or structural panel prices were to remain at or continue to decline significantly from current levels, our sales and profits could be negatively affected as compared to 2018 operating results. For further discussion of the impact of commodity prices on historical periods, see “-Operating Results.”

Consolidation of production homebuilders

Over the past fifteen years, the homebuilding industry has undergone consolidation and many production homebuilders have increased their market share. We expect that trend to continue as larger homebuilders have better liquidity and land positions relative to the smaller, less capitalized homebuilders. Our focus is on maintaining relationships and market share with these customers while balancing the competitive pressures we face in our markets with certain profitability expectations. We expect that our ability to maintain strong relationships with the largest production homebuilders will be vital to our ability to expand into new markets as well as grow our market share. While we generate significant sales from these homebuilders, our gross margins on sales to them tend to be lower than our gross margins on sales to other market segments. If the market share held by the largest production homebuilders continues to increase or we increase the percentage of our sales to these customers, our gross margins could be impacted.

Our ability to control expenses

We pay close attention to managing our working capital and operating expenses. We employ a LEAN process operating philosophy, which we refer to as the BMC Operating System, which encourages continuous improvement in our core processes to minimize waste, gain efficiencies, improve customer service, increase expense productivity, improve working capital and maximize profitability and cash flow. We regularly analyze our workforce productivity to achieve the optimum, cost-efficient labor mix for our facilities. Further, we pay careful attention to our logistics function and have implemented GPS-enabled telematics technology across our delivery fleet to improve customer service, driver safety and the productivity of our shipping and handling costs.

Mix of products sold

We typically realize greater gross margins on more highly engineered and customized products, or ancillary products that are often purchased based on convenience and are therefore less price sensitive to our customers. For example, sales of lumber and lumber sheet goods tend to generate lower gross margins due to their commodity nature and the relatively low switching costs of sourcing those products from different suppliers. Structural components and millwork, doors and windows often generate higher gross margins relative to other products. Homebuilders often use structural components in order to realize increased efficiency and improved quality. We believe shortening cycle time from start to completion is a key goal of homebuilders during periods of strong consumer demand or limited availability of framing labor. If the residential new construction market strengthens, we expect the use of structural components by homebuilders to increase.

27

Changes in customer sales mix

Our operating results may vary according to the amount and type of products we sell to each of our primary customer types: single-family homebuilders, remodeling contractors and multi-family, commercial and other contractors. The following table reflects our estimate of net sales by each customer type. Certain previously reported amounts for interim periods during the year ended December 31, 2018 and for the year ended December 31, 2017 were revised in the table below. The revisions were not material to the previously reported financial information.

	2018						2017						2016
(in thousands)	Net Sales		% of Sales		% Change vs. 2017		Net Sales		% of Sales		% Change vs. 2016		Net Sales		% of Sales
Single-family homebuilders	$	2,814,100	76.4	%	11.4	%	$	2,526,837	75.1	%	11.7	%	$	2,262,124	73.1	%
Remodeling contractors	427,346		11.6	%	12.3	%	380,460		11.3	%	2.5	%	371,018		12.0	%
Multi-family, commercial & other contractors	441,002		12.0	%	(3.9	)%	458,671		13.6	%	(0.4	)%	460,601		14.9	%
Total net sales	$	3,682,448	100.0	%	9.4	%	$	3,365,968	100.0	%	8.8	%	$	3,093,743	100.0	%

We tend to realize higher gross margins on sales to remodeling contractors due to the smaller product volumes purchased by those customers, as well as the more customized nature of the projects those customers generally undertake. Gross margins on sales to single-family homebuilders and multi-family, commercial and other contractors can vary based on a variety of factors, including the purchase volumes of the individual customer, the mix of products sold to that customer, the size and selling price of the project being constructed and the number of upgrades added to the project before or during its construction. 

Freight costs and fuel charges

A portion of our shipping and handling costs is comprised of diesel and other fuels purchased for our delivery fleet and handling equipment. According to the U.S. Energy Information Administration, the average retail price per gallon for No. 2 diesel fuel was $3.18, $2.65 and $2.31 for the years ended December 31, 2018, 2017 and 2016, respectively. For the years ended December 31, 2018, 2017 and 2016, we incurred costs of approximately $17.9 million, $14.8 million and $12.4 million, respectively, within selling, general and administrative expenses for diesel and other fuels used for our delivery fleet and handling equipment. Future increases in the cost of fuel, or inbound freight costs for the products we purchase, could impact our operating results and cash flows if we are unable to pass along these cost increases to our customers through increased prices.

2018 compared to 2017

Net sales

For the year ended December 31, 2018, net sales increased$316.5 million, or 9.4%, to $3,682.4 million from $3,366.0 million during the year ended December 31, 2017. We estimate net sales increased 5.0% from higher selling prices of lumber and lumber sheet goods, 2.1% from the net impact of the acquisitions of Shone Lumber, TexPly and Code Plus, partially offset by the disposition of Coleman Floor, 1.9% from other organic growth and 0.4% from an additional selling day.

We estimate approximately 76% of our net sales for the year ended December 31, 2018 were to customers engaged in new single-family construction. According to the U.S. Census Bureau, single-family housing starts in the South and West regions of the United States, which are our primary operating regions, increased approximately 4.4% for the year ended December 31, 2018 as compared to the prior year, while single-family houses completed increased 8.0% during the same time period. We estimate that net sales to single-family homebuilders and remodeling contractors increased 11.5% while net sales to multi-family, commercial and other contractors decreased 3.9%. Net sales to multi-family, commercial and other contractors were impacted by a slowdown in multi-family housing starts during the year ended December 31, 2017, which resulted in a lower backlog of projects at the beginning of the year ended December 31, 2018.

29

The following table shows net sales classified by major product category:

	2018				2017
(in thousands)	Net Sales		% of Sales		Net Sales		% of Sales		% Change
Structural components	$	622,105	16.9	%	$	522,619	15.5	%	19.0	%
Lumber & lumber sheet goods	1,286,481		34.9	%	1,114,219		33.1	%	15.5	%
Millwork, doors & windows	964,684		26.2	%	907,377		27.0	%	6.3	%
Other building products & services	809,178		22.0	%	821,753		24.4	%	(1.5	)%
Total net sales	$	3,682,448	100.0	%	$	3,365,968	100.0	%	9.4	%

The increase in net sales in our structural components product category was primarily related to an increase in single-family housing starts, an increase in net sales of our Ready-Frame^® product offering and an increase in average selling prices. The impact of price inflation during the year ended December 31, 2018 led to the increase in net sales in our lumber and lumber sheet goods product category, partially offset by an approximately 1% decline in organic volume. The decrease in our other building products and services product category was primarily related to a decrease in sales to multi-family, commercial and other contractors.

Cost of sales

For the year ended December 31, 2018, cost of sales increased$202.8 million, or 7.9%, to $2,773.2 million from $2,570.5 million during the year ended December 31, 2017. We estimate our cost of sales increased approximately 4.4% as a result of commodity cost inflation and approximately 2.1% due to the net impact of the acquisitions of Shone Lumber, TexPly and Code Plus, partially offset by the disposition of Coleman Floor, while other organic changes, including an additional selling day, increased our cost of sales by approximately 1.4%.

Gross profit

For the year ended December 31, 2018, gross profit increased$113.7 million, or 14.3%, to $909.2 million from $795.5 million for the year ended December 31, 2017, due primarily to an increase in net sales and a higher average gross margin. Our gross margin was 24.7% for the year ended December 31, 2018 and 23.6% for the year ended December 31, 2017. This increase was primarily due to an increase in the gross margin in our lumber and lumber sheet goods and structural components product categories of 230 basis points and 130 basis points, respectively, and an increase in net sales in our structural components and millwork, doors and windows product categories. Gross margins in our lumber and lumber sheet goods and structural components product categories were higher in the second half of the year due to a significant decrease in commodity costs beginning in July 2018, which decreased at a faster rate than our average selling prices.

Operating expenses

For the year ended December 31, 2018:

• selling, general and administrative expenses increased$60.7 million, or 9.8%, to $680.3 million, from $619.5 million for the year ended December 31, 2017. Approximately $14.9 million of this increase related to selling, general and administrative expenses of Shone Lumber, TexPly and Code Plus, approximately $38.1 million related to higher employee compensation, benefits and other employee-related costs, of which approximately $20.8 million related to profit-based incentives and approximately $4.5 million related to stock-based compensation, and approximately $2.8 million related to an increase in diesel fuel costs.

• depreciation expense decreased$3.4 million, or 7.9%, to $39.6 million from $43.0 million during the year ended December 31, 2017. This decrease resulted from certain fixed assets that became fully depreciated in 2017, partially offset by the depreciation of replacements and additions of delivery fleet, material handling equipment and operating equipment.

• amortization expense was $15.0 million compared to $16.0 million in the prior year. This decrease resulted from certain intangible assets that became fully amortized in 2017, partially offset by the amortization of intangible assets acquired in the Shone Lumber, TexPly and Code Plus acquisitions.

• the Company incurred $4.0 million of Merger and integration costs related to the ongoing integration of BMHC and SBS, consisting primarily of system integration costs, partially offset by a gain from disposition of property due to the integration, compared to $15.3 million for the year ended December 31, 2017. During the year ended December 31, 2017, the Company recognized approximately $2.8 million of expense related to the discontinuance of the ERP system previously utilized

30

by BMHC (“New ERP”) (see Note 6to the consolidated financial statements included in Item 8 of this Annual Report on Form 10-K for further description of the New ERP).

Interest expense

For the year ended December 31, 2018, interest expense was $24.0 million compared to $25.0 million for the year ended December 31, 2017. This decrease relates primarily to reduced borrowings under the revolving line of credit under the Credit Agreement (the “Revolver”). Non-cash amortization of debt issuance costs, which is included in interest expense, was $1.7 million for the years ended December 31, 2018 and 2017.

Other income, net

For the year ended December 31, 2018, other income, net, which was derived primarily from state and local tax incentive programs, interest income and service charges assessed on past due accounts receivable, was $10.6 million, compared to $5.7 million for the year ended December 31, 2017. This increase was primarily due to an increase in income from state and local tax incentive programs and interest income, partially offset by income recognized during the year ended December 31, 2017 related to the final settlement of insurance claims made by the Company for a fire at one of the Company’s facilities during 2015.

Income tax

For the years ended December 31, 2018 and 2017, income tax expense was $37.2 million and $24.4 million, respectively. The effective tax rate for the year ended December 31, 2018 was 23.7% compared to 29.8% for the year ended December 31, 2017. For the year ended December 31, 2018, the Company’s effective tax rate was higher than the Company’s federal and state statutory rates primarily due to nondeductible expenses. For the year ended December 31, 2017, the Company’s effective tax rate was lower than the Company’s federal and state statutory rates primarily due the enactment of the 2017 Tax Act, an Internal Revenue Code (“IRC”) section 199 manufacturing deduction, and excess windfall tax benefits of stock compensation deductions. Excluding the impacts of the 2017 Tax Act, our effective income tax rate in 2017 would have been 34.2%. The 2017 Tax Act, among other things, reduces the federal corporate income tax rate to 21% from 35%, effective January 1, 2018, resulting in a net income tax benefit of $3.6 million in 2017 primarily related to a reduction of our net deferred tax liability. In December 2018, the Company completed its accounting for the income tax effects of the 2017 Tax Act and recognized an additional tax benefit of $0.5 million for the year ended December 31, 2018.

2017 compared to 2016

Net sales

For the year ended December 31, 2017, net sales increased$272.2 million, or 8.8%, to $3,366.0 million from $3,093.7 million during the year ended December 31, 2016. The increase in net sales was primarily driven by the impact of commodity price inflation of approximately 4.2% and increased volume of approximately 2.8% related to existing operations, while the acquisitions of Code Plus and TexPly increased net sales by approximately 1.8%.

We estimate approximately 75% of our net sales for the year ended December 31, 2017 were to customers engaged in new single-family construction. According to the U.S. Census Bureau, single-family housing starts in the South and West regions of the United States, which are our primary operating regions, increased approximately 9.4% for the year ended December 31, 2017 as compared to the prior year, while single-family houses completed increased 8.7% during the same time period.

The following table shows net sales classified by major product category. Certain prior year amounts have been reclassified to conform to the current year presentation.

	2017				2016
(in thousands)	Net Sales		% of Sales		Net Sales		% of Sales		% Change
Structural components	$	522,619	15.5	%	$	461,761	14.9	%	13.2	%
Lumber & lumber sheet goods	1,114,219		33.1	%	938,563		30.3	%	18.7	%
Millwork, doors & windows	907,377		27.0	%	894,889		28.9	%	1.4	%
Other building products & services	821,753		24.4	%	798,530		25.9	%	2.9	%
Total net sales	$	3,365,968	100.0	%	$	3,093,743	100.0	%	8.8	%

The impact of commodity price inflation during the year ended December 31, 2017 contributed to the increase in net sales in our lumber and lumber sheet goods and structural components product categories.

31

Cost of sales

For the year ended December 31, 2017, cost of sales increased$218.7 million, or 9.3%, to $2,570.5 million from $2,351.8 million during the year ended December 31, 2016. Cost of sales for the year ended December 31, 2016 includes $2.9 million of expense incurred in relation to the sell-through of inventory which was stepped up in value in connection with the Merger. We estimate our cost of sales increased approximately 5.0% as a result of commodity cost inflation, 2.8% as a result of increased sales volumes related to existing operations and 1.6% related to the acquisitions of Code Plus and TexPly, partially offset by a 0.1% decrease as a result of the sell-through of inventory which was stepped up in value.

Gross profit

For the year ended December 31, 2017, gross profit increased$53.6 million, or 7.2%, to $795.5 million from $742.0 million for the year ended December 31, 2016, driven primarily by increased sales volumes and commodity price inflation. Our gross margin was 23.6% for the year ended December 31, 2017 and 24.0% for the year ended December 31, 2016. This decline resulted primarily from a decline in gross margin in lumber and lumber sheet goods and structural components and a greater percentage of total net sales derived from lumber and lumber sheet goods, which generally generate lower margins. Gross profit for the year ended December 31, 2016 was impacted by $2.9 million, or 0.1% of net sales, in relation to the sell-through of inventory which was stepped up in value in connection with the Merger.

Operating expenses

For the year ended December 31, 2017:

• selling, general and administrative expenses increased$47.7 million, or 8.4%, to $619.5 million, or 18.4% of net sales, from $571.8 million, or 18.5% of net sales, for the year ended December 31, 2016. Approximately $16.5 million of this increase related to increased shipping and handling costs to serve higher sales volumes related to existing operations, $12.5 million related to selling, general and administrative expenses of TexPly and Code Plus, $5.6 million related to an increase in the provision for workers’ compensation claims and $5.5 million related to increased health care costs. The remaining increase was primarily due to costs associated with five newly-opened facilities of approximately $4.7 million.

• depreciation expense increased$4.6 million, or 11.9%, to $43.0 million from $38.4 million during the year ended December 31, 2016. This increase primarily relates to replacements and additions of delivery fleet, material handling equipment and operating equipment.

• amortization expense was $16.0 million compared to $20.7 million in the prior year. This decrease resulted from certain intangible assets that became fully amortized in 2016, partially offset by the amortization of intangible assets acquired in the Code Plus and TexPly acquisitions.

• the Company incurred $15.3 million of Merger and integration costs related to the ongoing integration of BMHC and SBS, consisting primarily of severance, system integration costs and professional fees compared to $15.3 million for the year ended December 31, 2016. During the year ended December 31, 2017, the Company recognized approximately $2.8 million of expense related to the New ERP (see Note 6to the consolidated financial statements included in Item 8 of this Annual Report on Form 10-K for further description of the New ERP).

• the Company recognized asset impairment charges of $0.4 million related to the write down of real estate held for sale to the lower of depreciated cost or estimated fair value less expected disposition costs. During the year ended December 31, 2016, the Company decided to integrate all operations under the ERP system utilized by Legacy SBS, and to discontinue use of the New ERP (see Note 6 to the consolidated financial statements included in Item 8 of this Annual Report on Form 10-K for further description of the New ERP). In connection with this decision, the Company impaired capitalized software costs that had previously been recorded as construction-in-progress within property and equipment on the consolidated balance sheets.

Interest expense

For the year ended December 31, 2017, interest expense was $25.0 million compared to $30.1 million for the year ended December 31, 2016. This decrease relates primarily to reduced average borrowings under the Revolver and a decrease in interest expense on the Senior Notes after the Company redeemed $250.0 million of 9.0% senior secured notes (the “Extinguished Senior Notes”) with the proceeds from the issuance of $350.0 million of 5.5% Senior Notes during September 2016. Non-cash amortization of debt issuance costs, which is included in interest expense, was $1.7 million and $3.1 million for the years ended December 31, 2017 and 2016, respectively.

32

Loss on debt extinguishment

For the year ended December 31, 2016, the Company incurred a loss on debt extinguishment of $12.5 million related to the redemption of the Extinguished Senior Notes. The loss is made up of a call premium of $8.4 million and the write off of unamortized debt issuance costs and original issue discount of $4.1 million. There were no similar costs in 2017.

Other income, net

For the year ended December 31, 2017, other income, net was $5.7 million, which consisted primarily of income related to the final settlement of insurance claims made by the Company for a fire at one of the Company’s facilities during 2015, income from tax incentive programs and service charges assessed on past due accounts receivable. For the year ended December 31, 2016, other income, net was $4.1 million, which consisted primarily of insurance proceeds received during the year ended December 31, 2016 related to a fire at one of the Company’s facilities during 2015 and service charges assessed on past due accounts receivable.

Income tax

For the years ended December 31, 2017 and 2016, income tax expense was $24.4 million and $14.3 million, respectively. The effective tax rate for the year ended December 31, 2017 was 29.8% compared to 31.6% for the year ended December 31, 2016. For the year ended December 31, 2017, the Company’s effective tax rate was lower than the Company’s federal and state statutory rates primarily due to the enactment of the 2017 Tax Act, an IRC section 199 manufacturing deduction, and excess windfall tax benefits of stock compensation deductions. Excluding the impacts of the 2017 Tax Act, our effective income tax rate in 2017 would have been 34.2%. The 2017 Tax Act, among other things, reduces the federal corporate income tax rate to 21% from 35%, effective January 1, 2018, resulting in a net income tax benefit of $3.6 million in 2017 primarily related to a reduction of our net deferred tax liability. For the year ended December 31, 2016, the Company’s effective tax rate was lower than the Company’s federal and state statutory rates primarily due to the adoption of a state tax position related to IRC section 382 limitations on a state net operating loss carryforward, excess windfall tax benefits of stock compensation deductions, and an IRC section 199 manufacturing deduction.

Liquidity and Capital Resources

Our primary capital requirements are to fund working capital needs and operating expenses, meet required interest and principal payments and fund capital expenditures. During 2018 and 2017, our capital resources have primarily consisted of cash and cash equivalents generated through operating cash flows and borrowings under our Revolver.

Our liquidity at December 31, 2018 was $460.2 million, which includes $150.7 million in cash and cash equivalents and $309.5 million of unused borrowing capacity under our Revolver.

We believe that our cash flows from operations, combined with our current cash levels and available borrowing capacity, will be adequate to fund debt service requirements and provide cash, as required, to support our ongoing operations, capital expenditures, lease obligations, working capital and any share repurchase activity for at least the next 12 months.

In November 2018, the Company’s board of directors authorized a $75.0 million share repurchase program. Repurchases may be made at management’s discretion from time to time on the open market, subject to applicable laws, or through privately negotiated transactions. The repurchase program will expire on November 20, 2019 or may be suspended or discontinued at any time. During the year ended December 31, 2018, utilizing cash from operations, the Company repurchased 0.2 million shares at a weighted average price of $15.91 per share for a total cost of $2.9 million. Subsequent to December 31, 2018, the Company repurchased 0.7 million shares at a weighted average price of $16.82 per share for a total cost of $11.5 million.

(a) Effective January 1, 2018, as part of the Company’s adoption of Accounting Standards Update 2014-09, Revenue from Contracts with Customers, as amended (“Topic 606”), certain amounts within net current assets were reclassified. See Note 11 to the consolidated financial statements included in Item 8 of this Annual Report on Form 10-K for a discussion of the changes, including the reclassifications made, resulting from our adoption of Topic 606.

Accounts receivable, net, decreased$24.5 million from December 31, 2017 to December 31, 2018 primarily due to a decrease in days sales outstanding (measured against net sales in the fourth quarter of each period), which were 35 days at December 31, 2017 and 31 days at December 31, 2018.

Inventories, net, increased$0.2 million from December 31, 2017 to December 31, 2018. Inventory days on hand (measured against cost of sales in the fourth quarter of each period) were 43 days at December 31, 2017 and 44 days at December 31, 2018.

Accounts payable, accrued expenses and other current liabilities decreased$18.0 million from December 31, 2017 to December 31, 2018 primarily due to the timing of vendor payments.

Cash flows from operating activities

Net cash provided by operating activities was $210.0 million, $93.9 million and $106.9 million for the years ended December 31, 2018, 2017 and 2016, respectively, as summarized in the following table:

	Year Ended December 31,

Net cash provided by operating activities	$	210,025	$	93,934		$	106,888

Net cash provided by operating activities increased by $116.1 million for the year ended December 31, 2018 as compared to the year ended December 31, 2017. This increase was primarily related to improved profitability and changes in working capital and others assets and liabilities. Changes in working capital and other assets and liabilities relate primarily to the timing of cash received from customers and cash paid to vendors.

Net cash provided by operating activities decreased by $13.0 million for the year ended December 31, 2017 as compared to the year ended December 31, 2016. This decrease was primarily related to an increase in cash paid for income taxes, net of refunds, of $14.6 million, which resulted from an increase in taxable income and the utilization during the year ended December 31, 2016

34

of income tax overpayments made during the year ended December 31, 2015. Changes in other assets and liabilities relate primarily to the timing of cash received from customers and cash paid to vendors.

Cash flows from investing activities

Net cash used in investing activities was $54.9 million, $88.3 million and $33.7 million for the years ended December 31, 2018, 2017 and 2016, respectively, as summarized in the following table:

Net cash used in investing activities	$	(54,948	)	$	(88,271	)	$	(33,729	)

Cash used for the purchases of property, equipment and real estate for the years ended December 31, 2018, 2017 and 2016 resulted primarily from the purchases of vehicles and equipment to support increased sales volume and replace aged assets, and facility and technology investments to support our operations. Proceeds from the sale of property, equipment and real estate during the years ended December 31, 2018 and 2017 relates primarily to the sale of real estate of $10.3 million and $12.7 million, respectively.

Purchases of businesses, net of cash acquired, for the year ended December 31, 2018 related to the cash paid at closing for the acquisition of Shone Lumber and for the year ended December 31, 2017, related to the cash paid at closing for the acquisitions of TexPly and Code Plus.

Proceeds from the sale of business for the year ended December 31, 2018 related to the cash received at closing from the sale of Coleman Floor.

During the years ended December 31, 2018 and 2016, the Company received insurance proceeds related to a fire at one of the Company’s facilities during 2015, of which $2.0 million received during the year ended December 31, 2018 and $1.2 million received during the year ended December 31, 2016 related to property, plant and equipment damaged in the fire.

The Company made net repayments of $4.5 million and net borrowings of $4.5 million on the Revolver during the years ended December 31, 2018 and 2017, respectively. The net repayments during the year ended December 31, 2018 were the result of aggregate payments under the Revolver, partially offset by borrowings to fund the acquisition of Shone Lumber. A portion of the

35

net borrowings during the year ended December 31, 2017 was used to fund the acquisitions of Code Plus and TexPly during March 2017 and April 2017, respectively. The Company made net repayments of $152.3 million on the Revolver during the year ended December 31, 2016. Approximately $74 million of this repayment was funded through net proceeds from the September 2016 Senior Notes issuance, after payment of accrued interest, debt issuance costs and the call premium.

Payments on capital lease obligations and other notes decreased during the year ended December 31, 2018 compared to the years ended December 31, 2017 and 2016 due primarily to expiring leases and one-time payments made during the year ended December 31, 2017 related to the payoff of certain other notes.

During the year ended December 31, 2018, the Company’s board of directors authorized a $75.0 million share repurchase program. The Company repurchased 0.2 million shares under this share repurchase program at a weighted average price of $15.91 per share during the year ended December 31, 2018.

During September 2016, the Company completed an issuance of $350.0 million of Senior Notes and utilized a portion of the cash proceeds from the issuance to redeem in full the $250.0 million Extinguished Senior Notes. The Company incurred $6.7 million of debt issuance costs related to the Senior Notes, and paid a call premium of $8.4 million related to the Extinguished Senior Notes.

During May 2016, the Company commenced a public offering of 5,700,000 shares of its common stock by certain stockholders. In connection with the offering, the Company granted the underwriters an option to purchase up to an additional 855,000 shares of common stock. The underwriters exercised this option, which generated gross proceeds of $14.5 million and net proceeds of $13.8 million, after subtracting $0.7 million of underwriting commissions and other fees.

Proceeds from the exercise of stock options, which are included in other financing activities, net, were $1.3 million, $3.4 million and $1.3 million for the years ended December 31, 2018, 2017 and 2016, respectively. Other financing activities, net also includes net activity related to secured borrowings and repurchases of common stock in connection with the vesting of restricted stock and restricted stock unit awards. For the year ended December 31, 2018, other financing activities, net also includes the release of the holdback for the Code Plus acquisition.

Capital expenditures

Capital expenditures vary depending on prevailing business factors, including current and anticipated market conditions. We expect our 2019 capital expenditures, including the incurrence of capital lease obligations and net of proceeds from the sale of property, equipment and real estate to be approximately $80.0 million to $90.0 million primarily related to vehicles and equipment, including lease buyouts, to replace aged assets and support increased sales volume, and facility and technology investments to support our operations.

Senior secured notes

On September 15, 2016, the Company issued $350.0 million of Senior Notes. The Senior Notes mature on October 1, 2024 and are secured by a first priority lien on certain assets of the Company and a second priority lien on the collateral that secures the Credit Agreement, which collectively approximates substantially all assets of the Company. The interest rate is fixed at 5.5% and is payable semiannually on April 1 and October 1. The Indenture contains customary nonfinancial covenants, including restrictions on new indebtedness, issuance of liens and guarantees, investments, distributions to equityholders, asset sales and affiliate transactions. The Senior Notes were issued by BMC East, LLC, a 100% owned subsidiary of the Company, and are guaranteed by the Company and the other subsidiaries that guarantee the Credit Agreement. Each of the subsidiary guarantors is 100% owned, directly or indirectly, by the Company, and all guarantees are full and unconditional and joint and several. We were in compliance with all covenants under the Indenture as of December 31, 2018.

Revolving credit agreement

On December 1, 2015, in connection with the Merger, the Company entered into the Credit Agreement with Wells Fargo Capital Finance, as administrative agent, and certain other lenders. The Credit Agreement, as amended, which includes the Revolver, has an aggregate commitment of $375.0 million and a letters of credit sublimit of $100.0 million. The Revolver matures at the earlier of (i) December 1, 2020 and (ii) the date that is three months prior to the maturity of the Senior Notes (or if the Senior Notes are refinanced or repaid, the date that is three months prior to the new maturity date of the replacement notes or other indebtedness that replaced or refinanced the Senior Notes). The Revolver is subject to an asset-based borrowing formula on eligible accounts receivable, credit card receivables and inventory, in each case reduced by certain reserves.

Borrowings under the Revolver bear interest, at our option, at either the Base Rate (which means the higher of (i) the Federal Funds Rate plus 0.5%, (ii) the LIBOR rate plus 1.0% or (iii) the prime rate) plus a Base Rate Margin (which ranges from 0.25%

36

to 0.75% based on Revolver availability) or LIBOR plus a LIBOR Rate Margin (which ranges from 1.25% to 1.75% based on Revolver availability).The fee on any outstanding letters of credit issued under the Revolver ranges from 0.75% to 1.25%, depending on whether the letters of credit are fully cash collateralized. The fee on the unused portion of the Revolver is 0.25%.

The Credit Agreement contains customary nonfinancial covenants, including restrictions on new indebtedness, issuance of liens, investments, distributions to equityholders, asset sales and affiliate transactions. The Credit Agreement includes a financial covenant that requires us to maintain a minimum Fixed Charge Coverage Ratio of 1.00:1:00, as defined therein. However, the covenant is only applicable if excess availability under the Credit Agreement is less than or equal to the greater of (i) $33.3 million and (ii) 10% of the line cap, and remains in effect until excess availability has been greater than the greater of (i) $33.3 million and (ii) 10% of the line cap for 30 consecutive days. While there can be no assurances, based upon our forecast, we do not expect the financial covenant to become applicable during the year ended December 31, 2019. We were in compliance with all covenants under the Credit Agreement as of December 31, 2018.

Obligations under the Credit Agreement are guaranteed by our material subsidiaries. Obligations under the Credit Agreement, and the guarantees of those obligations, are secured by substantially all of our assets and those of the guarantors, subject to certain exceptions and permitted liens, including a first-priority security interest in certain accounts receivable, inventory and certain other assets of the Company and a second-priority security interest in substantially all other assets of the Company that secure the Senior Notes on a first-priority basis.

We had no outstanding borrowings with net availability of $309.5 million as of December 31, 2018. We had $61.0 million in letters of credit outstanding under the Credit Agreement as of December 31, 2018.

Contractual Obligations and Commercial Commitments

In the table below, we set forth our enforceable and legally binding obligations as of December 31, 2018. Some of the amounts included in the table are based on management’s estimates and assumptions about these obligations, including their duration, the possibility of renewal, anticipated actions by third parties and other factors. Because these estimates and assumptions are necessarily subjective, our actual payments may vary from those reflected in the table. We have not included liabilities related to self-insurance reserves in the table below, as these reserves represent an estimate of our future obligations and do not represent cash requirements arising from contractual payment obligations. Purchase orders made in the ordinary course of business and commitments that are cancellable on 30 days’ notice are excluded from the table below. Any amounts for which we are liable under purchase orders are reflected on the consolidated balance sheets as accounts payable and accrued liabilities.

	Payments Due by Period

(4)	Consists primarily of obligations to purchase vehicles which are enforceable and legally binding on us. Excludes purchase orders made in the ordinary course of business that are short-term or cancellable.

Off-Balance Sheet Arrangements

At December 31, 2018 and 2017, other than operating leases and letters of credit issued under the Credit Agreement described above, we had no material off-balance sheet arrangements with unconsolidated entities.

37

Seasonality and Other Factors

Our first and fourth quarters have historically been, and are generally expected to continue to be, adversely affected by weather patterns in some of our markets, causing reduced construction activity. In addition, quarterly results historically have reflected, and are expected to continue to reflect, fluctuations from period to period arising from the following:

• the volatility of lumber prices;

• the cyclical nature of the homebuilding industry;

• general economic conditions in the markets in which we compete;

• the pricing policies of our competitors;

• the production schedules of our customers; and

• the effects of weather.

The composition and level of working capital typically change during periods of increasing sales as we carry more inventory and receivables, although this is generally offset in part by higher trade payables to our suppliers. Working capital levels typically increase in the second and third quarters of the year due to higher sales during the peak residential construction season. These increases have in the past resulted in negative operating cash flows during this peak season, which historically have been financed through available cash or excess availability on our Revolver. Collection of receivables and reduction in inventory levels following the peak building and construction season have in the past positively impacted cash flow. In the past, we have also utilized our borrowing availability under credit facilities to cover working capital needs.

Recently Issued Accounting Pronouncements

Refer to Note 2 to the consolidated financial statements included in Item 8 of this Annual Report on Form 10-K for a summary of recently issued accounting pronouncements.

Critical Accounting Policies

Our discussion and analysis of operating results and financial condition are based upon our audited financial statements. The preparation of our financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures of contingent assets and liabilities. We base our estimates on past experience and other assumptions that we believe are reasonable under the circumstances, and we evaluate these estimates on an ongoing basis. Our critical accounting policies are those that materially affect our financial statements and involve difficult, subjective or complex judgments by management. Although these estimates are based on management’s best knowledge of current events and actions that may impact us in the future, actual results may be materially different from the estimates.

We believe the following critical accounting policies are affected by significant judgments and estimates used in the preparation of our consolidated financial statements and that the judgments and estimates are reasonable.

Revenue recognition

Effective January 1, 2018, we adopted Topic 606, which provides a comprehensive revenue recognition model requiring companies to recognize revenue for the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. Refer to Notes 2 and 11 to the consolidated financial statements included in Item 8 of this Annual Report on Form 10-K for additional information on our adoption of Topic 606.

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in Topic 606. Our building products contracts typically contain a promise to supply multiple distinct products and thus, they generally contain multiple performance obligations under Topic 606. Depending on the nature of the promises within our construction services contracts and whether they are distinct under Topic 606, there may be a single performance obligation or multiple performance obligations. For contracts with multiple performance obligations, the contract’s transaction price is allocated to each distinct performance obligation based on the standalone selling price of each distinct good or service, which is generally determined based on the prices charged to customers.

We recognize revenue for our building products contracts when control of the promised goods (the performance obligations) is transferred to our customers. This generally occurs at a point in time when the products are delivered and the customer obtains physical possession, legal title and the risks and rewards of ownership. However, for certain product offerings, products are customized to customer specifications and the customer benefits from our performance over time as deliveries are made. As such, we have determined that an output method based on units delivered best depicts the transfer of control to the customer.

38

We generally recognize revenue for our construction services contracts over time using cost based input methods. Periodic estimates of progress towards completion are made based on either a comparison of labor costs incurred to date with total estimated contract labor costs or total costs incurred to date with total estimated contract costs. Incurred costs represent work performed, which correspond and best depict transfer of control to the customer.

Contract revenues and contract costs to be recognized are dependent on the accuracy of estimates, including quantities of materials, labor productivity and other cost estimates. Historically, we have made reasonable estimates of the extent of progress towards completion and contract completion costs. Due to uncertainties inherent in the estimation process, it is possible that actual completion costs may vary from estimates.

Estimated losses on uncompleted contracts and changes in contract estimates reflect our best estimate of probable losses of unbilled receivables, and are recognized in the period such revisions are known and can be reasonably estimated. These estimates are recognized in cost of sales. Estimated losses on uncompleted contracts and changes in contract estimates are established by assessing estimated costs to complete, change orders and claims for uncompleted contracts. Assumptions for estimated costs to complete include material prices, labor costs, labor productivity and contract claims. Such estimates are inherently uncertain and it is possible that actual completion costs may vary from these estimates.

All sales recognized are net of allowances for discounts and estimated returns, based on historical experience. Taxes assessed by governmental authorities that are directly imposed on our revenue-producing transactions are excluded from sales. The Company accounts for shipping and handling costs associated with its contracts as a fulfillment cost and expenses these as incurred within selling, general and administrative expenses on the consolidated statements of operations.

Allowance for doubtful accounts

We maintain an allowance for doubtful accounts for estimated losses due to the failure of our customers to make required payments. Management believes the accounting estimate related to the allowance for doubtful accounts is a “critical accounting estimate” as it involves judgments about our customers’ ability to pay. The allowance for doubtful accounts is based on an assessment of individual past due accounts, historical write-off experience, accounts receivable aging, customer disputes and the business environment. Account balances are charged off when the potential for recovery is considered remote.

Management believes the allowance amounts recorded, in each instance, represent its best estimate of future outcomes. If there is a deterioration of a major customer’s financial condition, if the Company becomes aware of additional information related to the credit-worthiness of a major customer, or if future actual default rates on trade receivables in general differ from those currently anticipated, the Company may have to adjust its allowance for doubtful accounts, which would affect earnings in the period the adjustments were made.

Inventories

Inventories consist primarily of materials purchased for resale, including lumber and sheet goods, millwork, doors and windows as well as certain manufactured products, and are carried at the lower of cost or net realizable value. The cost of substantially all of our inventories is determined by the weighted average cost method, which approximates the first-in, first-out approach. We evaluate our inventory value at the end of each quarter to ensure that it is carried at the lower of cost or net realizable value. This evaluation includes an analysis of historical physical inventory results, a review of potential excess and obsolete inventories based on inventory aging and anticipated future demand. At least quarterly, each branch’s perpetual inventory records are adjusted to reflect any declines in net realizable value below inventory carrying cost. To the extent historical physical inventory results are not indicative of future results and if future events impact, either favorably or unfavorably, the salability of our products or our relationships with certain key suppliers, our inventory reserves could differ significantly, resulting in either higher or lower future inventory provisions.

Business combinations

For all acquisitions, we allocate the purchase price to the estimated fair values of the assets acquired and liabilities assumed as of the date of acquisition. The excess of the fair value of the purchase consideration over the fair values of the identifiable assets and liabilities is recorded as goodwill. Management makes significant estimates and assumptions when determining the fair value of assets acquired and liabilities assumed. These estimates include, but are not limited to, discount rates, projected future net sales, projected future expected cash flows and useful lives.

39

Valuation of goodwill, long-lived assets and amortizable other intangible assets

Our long-lived assets consist primarily of property, equipment, purchased intangible assets and goodwill. The valuation and the impairment testing of these long-lived assets involve significant judgments and assumptions, particularly as they relate to the identification of reporting units, asset groups and the determination of fair market value.

We test our tangible and intangible long-lived assets subject to amortization for impairment whenever facts and circumstances indicate that the carrying amount of an asset may not be recoverable. We test goodwill for impairment annually, or more frequently if triggering events occur indicating that there may be impairment.

We have recorded goodwill and perform testing for potential goodwill impairment at a reporting unit level. A reporting unit is an operating segment, or a business unit one level below an operating segment, for which discrete financial information is available, and for which management regularly reviews the operating results. Additionally, components within an operating segment are aggregated as a single reporting unit if they have similar economic characteristics. The Company’s five operating segments, which have been determined to be the Company’s reporting units, are the Mid-Atlantic, Southeast, Texas, Intermountain and Western divisions. The chief operating decision maker (“CODM”) reviews aggregate information to allocate resources and assess performance. Based on the CODM’s review, as well as the similar economic characteristics, nature of products, distribution methods and customers of the divisions, the Company has aggregated its operating segments into one reportable segment. We complete our annual impairment assessment during the third quarter of each year. We did not recognize any impairment for the years ended December 31, 2018, 2017 and 2016.

For impairment testing of long-lived assets, we identify asset groups at the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the assets. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the estimated fair value of the asset.

As discussed above, changes in management intentions, market events or conditions, projected future net sales, operating results, cash flow of our reporting units and other similar circumstances could affect the assumptions used in the impairment tests. Although management currently believes that the estimates used in the evaluation of goodwill and other long-lived assets are reasonable, differences between actual and expected net sales, operating results and cash flow could cause these assets to be impaired. If any asset were determined to be impaired, this could have a material adverse effect on our results of operations and financial position, but not our cash flow from operations.

Stock based compensation

During the years ended December 31, 2018 and 2017, the Company granted restricted stock unit awards and performance restricted stock unit awards to certain employees and directors.

We account for restricted stock unit awards by recording compensation expense over the requisite service period, using graded vesting, based on the award’s fair value at the date of grant. The fair value of restricted stock unit awards is based on the price of our publicly traded common stock at the date of grant. For restricted stock unit awards with performance conditions, we record compensation expense based on the expected number of units that will vest, which is adjusted, as appropriate, throughout the performance period.

We account for stock options granted to employees by recording compensation expense based on the award’s fair value, estimated on the date of grant using the Black-Scholes option-pricing model, which uses inputs including the fair value per share of our common stock, volatility, expected term of the awards, dividend yield and risk-free interest rate. The assumptions used in calculating the fair value of stock options represent our best estimates, based on management’s judgment and subjective future expectations. These estimates involve inherent uncertainties. If any of the assumptions used in the model change significantly, share-based compensation recorded for future awards may differ materially from that recorded for awards granted previously.

The Company accounts for forfeitures as they occur.

40

Casualty and health insurance

We carry insurance for general liability, auto liability and workers’ compensation exposures subject to deductibles or self-insured retentions that we believe to be reasonable under the circumstances, and we self-insure for employee and eligible dependent health care claims, with insurance purchased from independent carriers to cover individual claims in excess of the self-insured limits. The expected liability for unpaid claims, including incurred but not reported losses, is determined using the assistance of third-party actuaries and is reflected on the consolidated balance sheets as a liability with current and long-term components. We have elected not to discount this liability. The amount recoverable from insurance providers is reflected on the consolidated balance sheets in prepaid expenses and other current assets. Our accounting policy includes an internal evaluation and adjustment of our reserve for all insured losses on a quarterly basis. At least on an annual basis, we engage external actuarial professionals to independently assess and estimate the total liability outstanding, which is compared to the actual reserve balance at that time and adjusted accordingly.

Income taxes

In accordance with ASC 740, Income Taxes (“ASC 740”), we evaluate our deferred tax assets to determine if valuation allowances are required. In assessing the realizability of deferred tax assets, we consider both positive and negative evidence in determining whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The primary negative evidence considered includes the cumulative operating losses generated in prior periods. The primary positive evidence considered includes recent prior periods with cumulative operating income and the reversal of deferred tax liabilities related to depreciation and amortization that would occur within the same jurisdiction and during the carry-forward period necessary to absorb the state net operating losses and other deferred tax assets.

During 2018, the Company evaluated the positive and negative evidence in assessing the realizability of its deferred tax assets. As of December 31, 2018, we concluded that it is more likely than not that we will realize the benefit of our deferred tax assets, net of a state tax valuation allowance of $0.1 million.

ASC 740 also prescribes a recognition threshold and certain measurement principles for the financial statements related to tax positions taken or expected to be taken on a tax return. Under ASC 740, the impact of an uncertain tax position on an income tax return must be recognized at the largest amount that is more likely than not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. Additionally, ASC 740 provides guidance on derecognition, classification, interest and penalties associated with income taxes, accounting in interim periods, disclosures and transition requirements. As of December 31, 2018 and 2017, the Company recognizes no material uncertain tax positions.

On December 22, 2017, the President of the United States signed into law the 2017 Tax Act. This legislation significantly changes U.S. tax law by, among other things, lowering corporate income tax rates from a maximum 35% to a flat 21% rate, effective January 1, 2018. The SEC staff issued Staff Accounting Bulletin No. 118 to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the 2017 Tax Act. The Company has recognized the net tax benefit of $3.6 million related to the impact of the 2017 Tax Act for the remeasurement of deferred tax assets and liabilities and included this amount in its consolidated financial statements for the year ended December 31, 2017, on a provisional basis based on information available on that reporting date. In December 2018, the Company completed its accounting for the income tax effects of the 2017 Tax Act within the measurement period as provided under SEC Staff Accounting Bulletin No. 118, which resulted in recognizing an additional tax benefit of $0.5 million for the year ended December 31, 2018.

Consideration received from suppliers

We enter into arrangements with many of our suppliers providing for inventory purchase rebates (“supplier rebates”) upon achievement of specified volume purchasing levels. We accrue estimated supplier rebates monthly as part of cost of goods sold based on progress toward earning the supplier rebates, taking into consideration cumulative purchases of inventory to date and projected purchases through the end of the year. We estimate the rebates applicable to inventory on-hand at each period end based on the inventory turns of the related items.

Under certain circumstances, including if market conditions were to change, suppliers may change the terms of some or all of these programs. Although these changes would not affect the amounts which we have recorded related to product already purchased, it may impact our gross margins in future periods.

Item 7A.    Quantitative and Qualitative Disclosures About Market Risk

In the normal course of business, we are exposed to financial risks such as changes in interest rates and commodity price risk.

Interest Rate Risk

When we have loan amounts under our Revolver, we are exposed to interest rate risk arising from fluctuations in interest rates. During 2018, 2017 and 2016, we did not use any interest rate swap contracts to manage this risk. There were no outstanding borrowings under the Revolver as of December 31, 2018.

Commodity Price Risk

Many of the products we purchase and resell are commodities whose price is determined by the market’s supply and demand for such products. Price fluctuations in our selling prices and key costs have a significant effect on our financial performance. The markets for most of these commodities are cyclical and are affected by factors such as global economic conditions, including the strength of the U.S. housing market, changing trade policies and tariffs, changes in, or disruptions to, industry production capacity and changes in inventory levels and other factors beyond our control. During 2018, 2017 and 2016, we did not manage commodity price risk with derivative instruments, except for immaterial lumber future contracts. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Factors Affecting Our Operating Results—Commodity nature of our products” for further discussion.

We estimate that a 1% increase (decrease) in the sales price of lumber and lumber sheet goods, trusses and wall panels, assuming no change in our costs, would increase (decrease) our annual operating income by approximately $16.2 million (based on our operating results for the year ended December 31, 2018). Conversely, we estimate that a 1% increase (decrease) in the cost of lumber and lumber sheet goods, trusses and wall panels, assuming no offsetting pricing changes, would decrease (increase) our annual operating income by approximately $13.0 million (based on our operating results for the year ended December 31, 2018). However, we would likely adjust our pricing to offset any significant changes in our cost of goods.

Report of Independent Registered Public Accounting Firm

To theBoard of Directors and Stockholders of

BMC Stock Holdings, Inc.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of BMC Stock Holdings, Inc.and its subsidiaries(the “Company”) as of December 31, 2018and December 31, 2017,and the related consolidated statements of operations, of stockholders’ equity and of cash flows for each of the three years in the period ended December 31, 2018, including the related notes (collectively referred to as the “consolidated financial statements”).We also have audited the Company’s internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control - Integrated Framework(2013)issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidatedfinancial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2018and December 31, 2017, and the results of itsoperations and itscash flows for each of the three years in the period ended December 31, 2018in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control - Integrated Framework(2013)issued by the COSO.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s annual report on internal control over financial reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidatedfinancial statements and on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidatedfinancial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidatedfinancial statements included performing procedures to assess the risks of material misstatement of the consolidatedfinancial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidatedfinancial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidatedfinancial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

43

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

BMC STOCK HOLDINGS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(All amounts are presented in thousands except share and per share amounts.)

1.    Organization

These financial statements represent the financial statements of BMC Stock Holdings, Inc., and its subsidiaries. All references to “BMC” or the “Company” in this Annual Report on Form 10-K mean BMC Stock Holdings, Inc. and its subsidiaries.

The Company distributes lumber and building materials to new construction and repair and remodeling contractors. Additionally, the Company provides solution-based services to its customers, including component design, product specification and installation services.

2.    Summary of Significant Accounting Policies

Basis of presentation

The accompanying consolidated financial statements have been prepared by management in conformity with U.S generally accepted accounting principles (“U.S. GAAP”).

Principles of consolidation

The consolidated financial statements include all accounts of BMC and its wholly-owned subsidiaries. All material intercompany accounts and transactions have been eliminated in consolidation.

Use of estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company evaluates these estimates and judgments on an ongoing basis and bases its estimates on historical experience, current conditions and various other assumptions that are believed to be reasonable under the circumstances. The results of these estimates form the basis for making judgments about the carrying values of assets and liabilities as well as identifying and assessing the accounting treatment with respect to commitments and contingencies. The significant estimates which could change by a material amount in the near term include revenue recognition for construction services, accounts receivable reserves, estimated losses on uncompleted contracts and changes in contract estimates, inventory reserves, supplier rebates, goodwill impairment, impairment of property and equipment, insurance reserves, warranties and share-based compensation. Actual results may differ materially from these estimates under different assumptions or conditions.

Business and credit concentrations

The Company maintains cash at financial institutions in excess of federally insured limits. Accounts receivable potentially expose the Company to concentrations of credit risk. Mitigating this credit risk is collateral underlying certain accounts receivable (perfected liens or lien rights) as well as the Company’s analysis of a customer’s credit history prior to extending credit. Concentrations of credit risk with respect to accounts receivable are limited due to the Company’s large number of customers and their dispersion across various regions of the United States. At December 31, 2018 and 2017, no customer represented more than 10% of accounts receivable. For the years ended December 31, 2018, 2017 and 2016, no customer accounted for more than 10% of revenue.

The Company’s future results could be adversely affected by a number of factors including competitive pressure on sales and pricing, weather conditions, consumer spending and debt levels, interest rates, existing residential home sales and new home construction, lumber prices and product mix.

50

Cash and cash equivalents

Cash equivalents are highly liquid investments that are readily convertible to known amounts of cash and have a maturity of three months or less from the time of purchase. As of December 31, 2018 and 2017, the Company had cash equivalents of $146.1 million and $0, respectively. Cash equivalents are valued at amortized cost, which approximates fair value due to the short-term maturity of these instruments, and was classified as a Level 1 or Level 2 measurement in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 820, Fair Value Measurements and Disclosures (“ASC 820”).

Book overdrafts occur when purchases on corporate purchasing cards and checks written exceed available bank balances at a specific bank, despite there being cash at the Company’s other financial institutions. For accounting purposes, the Company reclassifies these book overdrafts to accounts payable on the consolidated balance sheets. Book overdrafts included in accounts payable were $0.1 million at December 31, 2018 and 2017.

Fair value of financial instruments

ASC 820 clarifies the definition of fair value, prescribes methods for measuring fair value, and establishes a fair value hierarchy to classify the inputs used in measuring fair value as follows:

Level 1	Inputs are unadjusted quoted prices in active markets for identical assets or liabilities available at the measurement date.
Level 2	Inputs are unadjusted quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, inputs other than quoted prices that are observable, and inputs derived from or corroborated by observable market data.
Level 3	Inputs are unobservable inputs which reflect the reporting entity’s own assumptions on what assumptions the market participants would use in pricing the asset or liability based on the best available information.

If a financial instrument uses inputs that fall in different levels of the hierarchy, the instrument is categorized based upon the lowest level of input that is significant to the fair value calculation.

Accounts receivable

Accounts receivable result from the extending of credit to trade customers for the purchase of goods and services. The terms generally provide for payment within 30 days of being invoiced. On occasion, when necessary to compete in certain circumstances, the Company will sell product under extended payment terms. Accounts receivable are stated at estimated net realizable value. The allowance for doubtful accounts is based on an assessment of individual past due accounts, historical write-off experience, accounts receivable aging, customer disputes and the business environment. Account balances are charged off when the potential for recovery is considered remote. The Company grants trade discounts on a percentage basis. The Company records an allowance against accounts receivable for the amount of discounts it estimates will be taken by customers. The discounts are recorded as a reduction to revenue when products are sold.

Consideration received from suppliers

The Company enters into agreements with many of its suppliers providing for inventory purchase rebates (“supplier rebates”) upon achievement of specified volume purchasing levels. Supplier rebates are accrued as part of cost of goods sold based on progress towards earning the supplier rebates, taking into consideration cumulative purchases of inventory to date and projected purchases through the end of the year. The Company estimates the rebates applicable to inventory on-hand at each period end based on the estimated percentage of supplier rebates to be earned. The Company also receives consideration from suppliers to promote their products (“marketing and advertising allowances”), which are accrued as part of cost of goods sold or selling, general and administrative expenses, depending on the nature of the allowance. Total rebates and marketing and advertising allowances receivable at December 31, 2018 and 2017 were $18.0 million and $23.3 million, respectively, included in prepaid expenses and other current assets.

Revenue recognition

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in Accounting Standards Update 2014-09, Revenue from Contracts with Customers, as amended (“Topic 606”). The Company’s building products contracts typically contain a promise to supply multiple distinct products and thus, they generally contain multiple performance obligations under Topic 606. Depending on the nature of the promises within the Company’s construction services contracts and whether they are distinct under Topic 606, there may be a single performance obligation or multiple performance

51

obligations. For contracts with multiple performance obligations, the contract’s transaction price is allocated to each distinct performance obligation based on the standalone selling price of each distinct good or service, which is generally determined based on the prices charged to customers.

The Company recognizes revenue for its building products contracts when control of the promised goods (the performance obligations) is transferred to the Company’s customers. This generally occurs at a point in time when the products are delivered and the customer obtains physical possession, legal title and the risks and rewards of ownership. However, for certain product offerings, products are customized to customer specifications and the customer benefits from the Company’s performance over time as deliveries are made. As such, the Company has determined that an output method based on units delivered best depicts the transfer of control to the customer.

The Company generally recognizes revenue for its construction services contracts over time using cost based input methods. Periodic estimates of progress towards completion are made based on either a comparison of labor costs incurred to date with total estimated contract labor costs or total costs incurred to date with total estimated contract costs. Incurred costs represent work performed, which correspond and best depict transfer of control to the customer.

Contract revenues and contract costs to be recognized are dependent on the accuracy of estimates, including quantities of materials, labor productivity and other cost estimates. Historically, the Company has made reasonable estimates of the extent of progress towards completion and contract completion costs. Due to uncertainties inherent in the estimation process, it is possible that actual completion costs may vary from estimates. Revenue recognized for performance obligations satisfied over time for the year ended December 31, 2018 represented approximately 26% of total revenues.

Estimated losses on uncompleted contracts and changes in contract estimates reflect the Company’s best estimate of probable losses of unbilled receivables, and are recognized in the period such revisions are known and can be reasonably estimated. These estimates are recognized in cost of sales. Estimated losses on uncompleted contracts and changes in contract estimates are established by assessing estimated costs to complete, change orders and claims for uncompleted contracts. Assumptions for estimated costs to complete include material prices, labor costs, labor productivity and contract claims. Such estimates are inherently uncertain and it is possible that actual completion costs may vary from these estimates.

All sales recognized are net of allowances for discounts and estimated returns, based on historical experience. Taxes assessed by governmental authorities that are directly imposed on the Company’s revenue-producing transactions are excluded from sales. The Company accounts for shipping and handling costs associated with its contracts as a fulfillment cost and expenses these as incurred within selling, general and administrative expenses.

Contract balances

The timing of revenue recognition, invoicing and cash collection affects receivables, contract assets and contract liabilities on the Company’s consolidated balance sheets. For building products contracts that contain performance obligations satisfied at a point in time, the Company recognizes revenue upon satisfaction of the performance obligation and then bills the customer, resulting in a receivable. For building products contracts that contain performance obligations satisfied over time, the Company recognizes revenue as the performance obligation is satisfied, but prior to billing, resulting in an unbilled receivable, as the Company has an unconditional right to payment.

For the Company’s construction services contracts, amounts are generally billed as work progresses in accordance with agreed-upon contractual terms. Revenue is also recognized over time as the performance obligations are satisfied, which can result in contract assets and liabilities, on a contract-by-contract basis, due to timing differences between billing and revenue recognition. Contract assets include unbilled amounts when the revenue recognized exceeds the amount billed to the customer. Conversely, contract liabilities include amounts that have been billed to the customer in excess of the revenue recognized.

At times, the Company will have a right to payment from previous performance that is conditional on something other than passage of time, such as retainage, which creates a contract asset. Conversely, the Company may receive advances from customers prior to the Company’s performance, which creates a contract liability.

Contract assets are reclassified to a receivable when the right to consideration becomes unconditional. The Company’s terms generally provide for payment within 30 days of being invoiced. On occasion, when necessary to compete in certain circumstances, the Company will offer extended payment terms, which do not exceed one year.

52

Shipping and handling costs

The Company includes shipping and handling costs in selling, general and administrative expenses and depreciation expense on the consolidated statements of operations. Shipping and handling costs included in selling, general and administrative expenses were $189.6 million, $172.2 million and $152.7 million for the years ended December 31, 2018, 2017 and 2016, respectively. Shipping and handling costs included in depreciation expense were $22.9 million, $24.8 million and $20.9 million for the years ended December 31, 2018, 2017 and 2016, respectively.

Property and equipment

Property and equipment are stated at cost. Expenditures for renewals and betterments, which extend the useful lives of assets, are capitalized while maintenance and repairs are charged to expense as incurred. Property and equipment obtained through acquisition are stated at estimated fair market value as of the acquisition date, and are depreciated over their estimated remaining useful lives, which may differ from the Company’s stated policies for certain assets. Gains and losses related to the sale of property and equipment are recorded as selling, general and administrative expenses.

Property and equipment are depreciated using the straight-line method and are generally depreciated over the following estimated service lives:

Buildings and improvements	3–30 years
Leasehold improvements	Lesser of life of the asset or remaining
	lease term, and not to exceed 15 years
Furniture, fixtures and equipment	2–10 years
Vehicles	4–10 years

Property and equipment that is expected to be sold within the next twelve months, is actively marketed in its current condition for a price that is reasonable in comparison to its estimated fair value and meets other relevant held-for-sale criteria are classified as assets held for sale. Assets held for sale are measured at the lower of carrying amount or fair value less costs to sell and are no longer depreciated. An impairment for assets held for sale is recognized if the carrying amount is not recoverable. Assets held for sale were not presented separately and were classified as other long-term assets in the consolidated balance sheets and were $1.3 million and $2.3 million at December 31, 2018 and 2017, respectively.

Goodwill and other intangible assets

At least annually, or more frequently as changes in circumstances indicate, the Company tests goodwill for impairment. To the extent that the carrying value of the net assets of any of the reporting units having goodwill is greater than their estimated fair value, the Company may be required to record impairment charges. The Company’s five operating segments, which have been determined to be the Company’s reporting units, are the Mid-Atlantic, Southeast, Texas, Intermountain and Western divisions. The chief operating decision maker (“CODM”) reviews aggregate information to allocate resources and assess performance. Based on the CODM’s review, as well as the similar economic characteristics, nature of products, distribution methods and customers of the divisions, the Company has aggregated its operating segments into one reportable segment. The Company is required to make certain assumptions and estimates regarding the fair value of the reporting units containing goodwill when assessing for impairment. Changes in the fact patterns underlying such assumptions and estimates could ultimately result in the recognition of additional impairment losses.

The Company completes its annual impairment assessment during the third quarter of each year. The Company did not recognize any impairment for the years ended December 31, 2018, 2017 and 2016. The Company may consider qualitative factors as part of its annual impairment assessment to determine whether it is more likely than not that a reporting unit’s carrying value exceeds its fair value. If the Company’s qualitative assessment indicates that goodwill impairment is more likely than not, the Company performs the two-step impairment test. Alternatively, the Company may bypass the qualitative test and initiate goodwill impairment testing with the first step of the two-step goodwill impairment test. During the first step of the goodwill impairment test, the fair value of the reporting unit is compared to its carrying value, including goodwill. The Company may derive a reporting unit’s fair value through a combination of the market approach (a guideline transaction method) and the income approach. The income approach uses a reporting unit’s projection of estimated future cash flows that is discounted at a market derived weighted average cost of capital. The projection uses management’s best estimates of economic and market conditions over the projected period including growth rates in sales, costs, estimates of future expected changes in operating margins and cash expenditures.

If the fair value of a reporting unit exceeds its carrying value, then the Company concludes no goodwill impairment has occurred. If the carrying value of the reporting unit exceeds its fair value, the Company performs the second step of the goodwill impairment

53

test to measure possible goodwill impairment loss. During the second step, the implied fair value of the reporting unit’s goodwill is compared to the carrying value of its goodwill. If the carrying value of the reporting unit’s goodwill exceeds the implied fair value of the goodwill, the Company would recognize an impairment loss in an amount equal to the excess, not to exceed the carrying value of the reporting unit’s goodwill.

Acquired intangible assets other than goodwill are amortized over their weighted average amortization period unless they are determined to be indefinite. Acquired intangible assets are carried at cost, less accumulated amortization. For intangible assets purchased in a business combination, the estimated fair values of the assets received are used to establish the carrying value. The fair value of acquired intangible assets is determined using common valuation techniques, and the Company employs assumptions developed using the perspective of a market participant.

Impairment of long-lived assets

Long-lived assets, such as property, equipment and purchased intangible assets subject to amortization, are reviewed for impairment whenever facts and circumstances indicate that the carrying amount of an asset may not be recoverable. For impairment testing of long-lived assets, the Company identifies asset groups at the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the assets. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the estimated fair value of the asset.

Treasury stock

During the year ended December 31, 2018, the Company’s board of directors authorized a $75.0 million share repurchase program. Repurchases may be made at management’s discretion from time to time on the open market, subject to applicable laws, or through privately negotiated transactions. The repurchase program will expire on November 20, 2019 or may be suspended or discontinued at any time. During the year ended December 31, 2018, utilizing cash from operations, the Company repurchased 0.2 million shares at a weighted average price of $15.91 per share for a total cost of $2.9 million. These repurchased shares are available for future issuance and are reflected as treasury stock, at cost, on the consolidated balance sheet as of December 31, 2018. As of December 31, 2018, the Company had approximately $72.1 million of capacity remaining under the current share repurchase authorization. Subsequent to December 31, 2018, the Company repurchased 0.7 million shares at a weighted average price of $16.82 per share for a total cost of $11.5 million.

Employees have the option to surrender shares to the Company to satisfy their tax withholding obligations in connection with the vesting of restricted stock and restricted stock unit awards. These surrendered shares are reflected as treasury stock, at cost, on the consolidated balance sheet as of December 31, 2018 and 2017.

Merger and integration costs

Merger and integration costs related to the ongoing integration of Building Materials Holding Corporation (“BMHC”) and Stock Building Supply Holdings, Inc. (“SBS”), as a result of the 2015 merger transaction, consist primarily of severance, rebranding, system integration costs and professional fees.

Income taxes

The Company accounts for income taxes in accordance with ASC 740, Income Taxes (“ASC 740”), which requires an asset and liability approach for measuring deferred taxes based on temporary differences between the financial statement and tax basis of assets and liabilities existing at each balance sheet date using enacted tax rates for years in which taxes are expected to be paid or recovered.

The Company evaluates its deferred tax assets on a quarterly basis to determine whether a valuation allowance is required. In accordance with ASC 740, the Company assesses whether a valuation allowance should be established based on its determination of whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets depends primarily on: (i) the Company’s ability to carry back net operating losses to tax years where it has previously paid income taxes based on applicable federal law; (ii) the timing of the reversal of deferred tax liabilities and (iii) the Company’s ability to generate future taxable income during the periods in which the related deferred tax assets are deductible. The assessment of a valuation allowance includes giving appropriate consideration to all positive and negative evidence related to the realization of the deferred tax asset. This assessment considers, among other things, the nature, frequency and severity of current and cumulative losses, forecasts of future profitability, the duration of statutory carryforward periods, the Company’s experience with operating loss and tax credit carryforwards not expiring unused and tax planning alternatives. Significant judgment

54

is required in determining the future tax consequences of events that have been recognized in the Company’s consolidated financial statements and/or tax returns. Actual outcomes of these future tax consequences could differ materially from the outcomes that the Company currently anticipates.

ASC 740 defines the methodology for recognizing the benefits of uncertain tax return positions as well as guidance regarding the measurement of the resulting tax benefits. These provisions require an enterprise to recognize the financial statement effects of a tax position when it is more likely than not, which is defined as a likelihood of more than 50%, based on technical merits, that the position will be sustained upon examination. The evaluation of whether a tax position meets the more likely than not recognition threshold requires a substantial degree of judgment by management based on the individual facts and circumstances. Actual results could differ from estimates. The Company had no material uncertain tax positions as of December 31, 2018.

The Company’s policy is to recognize interest and penalties related to income tax liabilities and unrecognized tax benefits in income tax expense.

Casualty and health insurance

The Company carries insurance for general liability, auto liability and workers’ compensation exposures subject to deductibles or self-insured retentions it believes to be reasonable under the circumstances, and the Company self-insures for employee and eligible dependent health care claims, with insurance purchased from independent carriers to cover individual claims in excess of the self-insured limits. The expected liability for unpaid claims, including incurred but not reported losses, is reflected on the consolidated balance sheets as a liability with current and long-term components. The amount recoverable from insurance providers is reflected on the consolidated balance sheets in prepaid expenses and other current assets. Provisions for losses are developed from actuarial valuations that rely upon the Company’s past claims experience, which considers both the frequency and settlement of claims. The casualty and health insurance liabilities are recorded at their undiscounted value.

In January 2015, the Company entered into a retroactive reinsurance contract to transfer the risk of loss of certain insurance reserves for workers’ compensation claims incurred from 2006 to 2011 to a reinsurer. Pursuant to the reinsurance contract, the reinsurer is obligated to pay an aggregate maximum of $17.5 million for these claims with any excess borne by the Company. The Company maintains the insurance reserves related to these claims as a liability on its consolidated balance sheet with an offsetting reinsurance receivable, which includes current and long-term components. As of December 31, 2018 and 2017, the carrying value of the insurance reserves related to these claims and the offsetting reinsurance receivable was $3.7 million and $4.5 million, respectively. Changes in these claims are recorded as an increase or decrease in the insurance reserves and corresponding increase or decrease in the reinsurance receivable. Additionally, the Company monitors the financial condition of the reinsurer to minimize its exposure to significant losses from reinsurer insolvency.

Retirement savings program

The Company sponsors a defined contribution retirement savings plan. The Company has recorded expense of $5.9 million, $5.2 million and $4.6 million related to employer contributions for the years ended December 31, 2018, 2017 and 2016, respectively. These expenses are recorded to either selling, general and administrative expenses or cost of sales on the consolidated statements of operations, depending on the classification of the employee.

Lease obligations

The Company recognizes lease obligations with fixed escalations of rental payments on a straight-line basis over the lease term, with the amount of rental expense in excess of lease payments recorded as a deferred rent liability. Lease incentives received are also recorded as a deferred rent liability and are amortized as reductions to rent expense over the lease term. As of December 31, 2018 and 2017, the Company had a deferred rent liability of $5.0 million and $4.2 million, respectively, included in accrued expenses and other liabilities and other long-term liabilities on the consolidated balance sheets.

Advertising and promotion

Costs associated with advertising and promoting products and services are expensed in the period incurred. Cooperative advertising allowances that are reimbursement of specific, incremental and identifiable costs incurred to promote vendors’ products are recorded as an offset against advertising expenses in selling, general and administrative expenses. If those conditions are not met, the cooperative advertising allowances are recorded as a reduction in inventory and a subsequent reduction in cost of goods sold when the related product is sold. For the years ended December 31, 2018, 2017 and 2016, the Company recorded $4.9 million, $5.8 million and $3.7 million, respectively, of advertising and promotion expenses, net of cooperative advertising allowances, in selling, general and administrative expenses.

55

Stock-based compensation

In accordance with the requirements of ASC 718, Compensation—Stock Compensation(“ASC 718”), the Company measures and recognizes compensation expense for all share-based payment awards made to employees using a fair value based pricing model. The compensation expense is recognized over the requisite service period, using graded vesting.

Debt issuance costs

Costs incurred in connection with the Company’s revolving line of credit and senior secured notes are capitalized and amortized over the term of the applicable agreement. Total debt issuance costs, net of accumulated amortization, were $6.4 million and $8.1 million as of December 31, 2018 and 2017, respectively. Debt issuance costs related to the Company’s revolving line of credit and senior secured notes are included in other long-term assets and long-term debt, respectively, on the consolidated balance sheets. Amortization of debt issuance costs for the years ended December 31, 2018, 2017 and 2016 was $1.7 million, $1.7 million and $3.1 million, respectively, and is included in interest expense on the consolidated statements of operations.

Derivatives

The Company will occasionally enter into derivative instruments to offset existing or expected risks associated with fluctuations in commodity prices. The Company does not enter into derivative instruments for speculative or trading purposes. The Company recognizes all derivative instruments as assets or liabilities in the Company’s balance sheets at fair value. Changes in the fair value of derivative instruments that are not designated as hedges or that do not meet the hedge accounting criteria are reported in earnings. The Company elected not to designate any new derivative instruments as hedges for the years ended December 31, 2018, 2017 or 2016, and therefore, all changes in the fair market value of the derivative instruments have been reported in cost of goods sold on the consolidated statements of operations.

Warranty expense

The Company has warranty obligations with respect to most manufactured products. As of December 31, 2018 and 2017, the Company had warranty liabilities of $2.9 million and $2.5 million, respectively, included in accrued expenses and other liabilities on the consolidated balance sheets.

Comprehensive income

Comprehensive income is equal to the net income for all periods presented.

Statement of cash flows

Proceeds from revolving line of credit and Repayments of proceeds from revolving line of credit as presented on the Consolidated Statements of Cash Flows includes all cash activities and transactions between the Company and its associated lenders in relation to the revolving line of credit, excluding interest and fees, and is specifically inclusive of operating cash receipts which are automatically applied to the revolving line of credit pursuant to a cash sweep agreement. See Note 9 for further details on the Company’s revolving line of credit.

Recently adopted accounting pronouncements

In May 2014, the FASB issued Topic 606. Topic 606 provides a comprehensive revenue recognition model requiring companies to recognize revenue for the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. The guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. The Company adopted Topic 606 on January 1, 2018 using the modified retrospective transition method. See Note 11 for further details.

In August 2016, the FASB issued Accounting Standards Update 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). ASU 2016-15 was issued to decrease the diversity in practice of how certain cash receipts and cash payments are presented and classified in the statement of cash flows by providing guidance on eight specific cash flow issues. Retrospective application is required. ASU 2016-15 became effective for the Company’s annual and interim periods beginning on January 1, 2018. The adoption of the standard did not have a material impact on the Company’s consolidated financial statements.

In November 2016, the FASB issued Accounting Standards Update 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (“ASU 2016-18”). ASU 2016-18 requires that the statement of cash flows include restricted cash in the beginning and end-of-period total amounts shown and that the statement of cash flows explain the changes in restricted cash during the period.

56

Retrospective application is required. ASU 2016-18 became effective for the Company’s annual and interim periods beginning on January 1, 2018. The adoption of the standard did not have a material impact on the Company’s consolidated financial statements.

In January 2017, the FASB issued Accounting Standards Update 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business (“ASU 2017-01”). ASU 2017-01 provides guidance in determining when a set of assets and activities meets the definition of a business. Prospective application is required. ASU 2017-01 became effective for the Company’s annual and interim periods beginning on January 1, 2018. The adoption of the standard did not have a material impact on the Company’s consolidated financial statements.

In February 2017, the FASB issued Accounting Standards Update 2017-05, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets (“ASU 2017-05”). ASU 2017-05 clarifies the scope of Subtopic 610-20, which provides guidance for recognizing gains and losses from the sale or transfer of nonfinancial assets in contracts with noncustomers. ASU 2017-05 also provides guidance for partial sales of nonfinancial assets. ASU 2017-05 became effective for the Company’s annual and interim periods beginning on January 1, 2018. The adoption of the standard did not have a material impact on the Company’s consolidated financial statements.

In May 2017, the FASB issued Accounting Standards Update 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting (“ASU 2017-09”). ASU 2017-09 provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting under ASC 718. ASU 2017-09 is to be applied prospectively to an award modified on or after the adoption date. ASU 2017-09 became effective for the Company’s annual and interim periods beginning on January 1, 2018. The adoption of the standard did not have a material impact on the Company’s consolidated financial statements.

In March 2018, the FASB issued Accounting Standards Update 2018-05, Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118 (“ASU 2018-05”). ASU 2018-05 adds paragraphs to the ASC pursuant to SEC Staff Accounting Bulletin No. 118, which addresses the application of U.S. GAAP in situations when a company does not have the necessary information available, prepared or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Cuts and Jobs Act (the “2017 Tax Act”). ASU 2018-05 provides entities with a one year measurement period from the December 22, 2017 enactment date in order to complete the accounting. The Company recognized a provisional net tax benefit of $3.6 million related to the impact of the 2017 Tax Act during the year ended December 31, 2017. In the fourth quarter of 2018, the Company completed its accounting for the income tax effects of the 2017 Tax Act within the measurement period as provided under ASU 2018-05, which resulted in recognizing an additional tax benefit of $0.5 million for the year ended December 31, 2018.

Recently issued accounting pronouncements not yet adopted

In February 2016, the FASB issued Accounting Standards Update 2016-02, Leases, and issued subsequent amendments to the initial guidance to provide additional clarification on specific topics (“ASU 2016-02”). ASU 2016-02 establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the statement of operations. The Company plans to adopt the standard on January 1, 2019, utilizing the transition option provided by Accounting Standards Update 2018-11, Leases (Topic 842): Targeted Improvements, which the FASB issued in July 2018 and allows the Company to apply the guidance in ASU 2016-02 as of the adoption date, while applying the legacy guidance in ASC 840, Leases, including its disclosure requirements, in the comparative periods. As a lessee, certain of the Company’s leases under existing guidance are classified as operating leases that are not recorded on the balance sheet but are recorded in the statement of operations as expense is incurred. Upon adoption of the standard, the Company will be required to record substantially all leases on the balance sheet as a ROU asset and a lease liability. The Company expects to utilize the package of practical expedients permitted by the transition guidance in ASU 2016-02, which allows the Company to carry forward its identification of contracts that are or contain leases, its historical lease classification and its initial direct costs for existing leases. The Company currently expects to recognize lease liabilities for its operating leases totaling between $110.0 million and $125.0 million upon adoption, of which between $22.0 million and $37.0 million will be classified as a current liability. The initial ROU assets recognized will be equal to the initial operating lease liabilities, adjusted for the balance on adoption date of prepaid and accrued rent, lease incentives, unamortized initial direct costs and unamortized assets and liabilities related to favorable and unfavorable lease terms. The Company currently expects to recognize ROU assets totaling between $105.0 million and $120.0 million upon adoption. The Company does not expect adoption of the standard to have a material impact on the Company’s historical capital leases, which will be presented as finance leases under ASU 2016-02. See Note 13 for further information on the Company’s leases.

In June 2016, the FASB issued Accounting Standards Update 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 amends the impairment model by requiring entities to use a forward-looking approach based on expected losses to estimate credit losses on certain types of financial instruments, including trade receivables. ASU 2016-13 is effective for the Company’s annual and interim periods beginning on January 1, 2020, with early adoption permitted beginning January 1, 2019. Modified retrospective application is required, with certain exceptions. The Company expects to adopt the standard on January 1, 2020 and continues to evaluate the impact of the standard on its consolidated financial statements.

In January 2017, the FASB issued Accounting Standards Update 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). ASU 2017-04 simplifies the accounting for goodwill impairment by removing Step 2 of the goodwill impairment test, which requires computation of the implied fair value of a reporting unit’s goodwill. The amount of a goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. ASU 2017-04 is effective for the Company’s annual goodwill impairment test and any interim tests during the Company’s annual and interim periods beginning on January 1, 2020. Early adoption is permitted for goodwill impairment tests performed on testing dates after January 1, 2017. Prospective application is required. The adoption of the standard is not expected to have a material impact on the Company’s consolidated financial statements.

In August 2018, the FASB issued Accounting Standards Update 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, and issued subsequent amendments to the initial guidance to provide additional clarification on specific topics (“ASU 2018-13”). ASU 2018-13 modifies the disclosure requirements on fair value measurements by removing, modifying and adding certain disclosure requirements in ASC 820. ASU 2018-13 is effective for the Company’s annual and interim periods beginning on January 1, 2020, with early adoption permitted. Certain disclosures in ASU 2018-13 are required to be applied prospectively, while others require retrospective application. The Company is evaluating the impact of the standard on its consolidated financial statements.

3.    Acquisitions and Disposition

For all acquisitions, the Company allocates the purchase price to assets acquired and liabilities assumed as of the date of acquisition based on the estimated fair values at the date of acquisition. The excess of the fair value of the purchase consideration over the fair values of the identifiable assets and liabilities is recorded as goodwill. Management makes significant estimates and assumptions when determining the fair value of assets acquired and liabilities assumed. These estimates include, but are not limited to, discount rates, projected future net sales, projected future expected cash flows and useful lives.

The Company accounts for all acquisitions using the acquisition method of accounting under ASC 805, Business Combinations (“ASC 805”), whereby the results of operations of the acquired company are included in the Company’s consolidated financial statements beginning on the acquisition date.

2018 Disposition

On November 1, 2018, the Company completed the sale of substantially all of the assets and certain liabilities of its Coleman Floor business (“Coleman Floor”) for a preliminary sale price of $7.8 million, subject to certain customary post-closing adjustments. For the year ended December 31, 2018, the net sales of Coleman Floor represented approximately 1% of the Company’s net sales. The sale does not represent a strategic shift under ASC 205, Presentation of Financial Statements, and as such, is not reported as a discontinued operation in the Company’s consolidated financial statements. The Company recognized a loss on the sale of $0.3 million, which is included in other income, net in the consolidated statements of operations.

2018 Acquisition

On March 1, 2018, the Company acquired substantially all of the assets and assumed certain liabilities of W.E. Shone Co. (“Shone Lumber”), a supplier of building materials in the state of Delaware, for a preliminary purchase price of $22.4 million. This acquisition enhances the Company’s value-added offerings and footprint in the Mid-Atlantic region. The preliminary purchase price includes a holdback which, after certain post-closing adjustments, requires the Company to pay $1.4 million to the sellers one year from the closing date. The holdback amount may be further reduced under certain circumstances. The Company funded the transaction through available cash and borrowings on the Company’s revolving line of credit.

The purchase price allocation resulted in the recognition of goodwill of $2.5 million, a customer relationship intangible asset of $7.0 million, accounts receivable of $6.4 million, inventory of $8.8 million, property and equipment of $2.9 million and total current liabilities of $5.3 million, as well as other operating assets. The customer relationship intangible asset has a useful life of 9 years. Goodwill represents the future economic benefits expected to arise from other intangible assets acquired that do not qualify

58

for separate recognition, including assembled workforce and non-contractual relationships, as well as expected future synergies. All of the goodwill recognized is expected to be deductible for tax purposes.

For the year ended December 31, 2017, Shone Lumber generated net sales of approximately $70.7 million. The Company incurred transaction costs of $0.2 million for the year ended December 31, 2018, which are included in selling, general and administrative expenses in the consolidated statements of operations.

Net sales and estimated pre-tax earnings for Shone Lumber included in the consolidated statements of operations from the March 1, 2018 acquisition date to December 31, 2018 were $60.9 million and $3.2 million, respectively. The impact of the acquisition was not considered significant for the reporting of pro forma financial information.

2017 Acquisitions

On April 3, 2017, the Company acquired substantially all of the assets and assumed certain liabilities of Texas Plywood & Lumber Company, Inc. (“TexPly”), a supplier of production millwork and doors in the Dallas-Fort Worth area, for a purchase price of $31.7 million. This acquisition enhances the Company’s value-added offerings and footprint in the Dallas-Fort Worth market. The Company funded the transaction through borrowings on the Company’s revolving line of credit.

The purchase price allocation resulted in the recognition of goodwill of $3.6 million, a customer relationship intangible asset of $13.6 million, accounts receivable of $5.2 million, inventory of $3.9 million and real property of $5.4 million, as well as other operating assets and liabilities. The customer relationship intangible asset has a useful life of 13 years. Goodwill represents the future economic benefits expected to arise from other intangible assets acquired that do not qualify for separate recognition, including assembled workforce and non-contractual relationships, as well as expected future synergies. All of the goodwill recognized is expected to be deductible for tax purposes.

On March 27, 2017, the Company acquired substantially all of the assets and assumed certain liabilities of Code Plus Components, LLC (“Code Plus”), a manufacturer of structural components located in Martinsburg, West Virginia, for a purchase price of $7.1 million. This acquisition allowed the Company to add truss manufacturing capability to its value-added offerings in the Washington, DC metro area. The acquisition includes an earnout provision that requires the Company to pay the sellers an additional $0.8 million during the year ended December 31, 2019, due to the acquired operations achieving certain performance targets from the acquisition date through December 31, 2018. The Company funded the transaction through borrowings on the Company’s revolving line of credit.

The purchase price allocation resulted in the recognition of goodwill of $3.4 million, a customer relationship intangible asset of $2.3 million and a non-compete agreement intangible asset of $0.5 million, as well as other operating assets and liabilities. The customer relationship intangible asset and non-compete agreement intangible asset have useful lives of 12 years and 5 years, respectively. Goodwill represents the future economic benefits expected to arise from other intangible assets acquired that do not qualify for separate recognition, including assembled workforce and non-contractual relationships, as well as expected future synergies. All of the goodwill recognized is expected to be deductible for tax purposes.

Net sales and estimated pre-tax earnings for Code Plus and TexPly, in aggregate, included in the consolidated statements of operations were $54.3 million and $3.2 million, respectively, for the year ended December 31, 2017. The impact of the Code Plus and TexPly acquisitions was not considered significant for the reporting of pro forma financial information.

Impairment of BMHC ERP System

During 2013, BMHC selected a new third-party software vendor for its planned Enterprise Resource Planning (“New ERP”) system and began incurring costs related to design, development and implementation of the New ERP. BMHC also began paying an annual licensing fee. During March 2016, the Company decided to integrate all operations under the Enterprise Resource Planning system utilized by Legacy SBS (the “Legacy SBS ERP system”) and to discontinue the use of the New ERP. In connection with this decision, the Company recorded asset impairment charges of approximately $11.9 million in its consolidated statement of operations for the year ended December 31, 2016 related to capitalized software development costs for New ERP functionality that the

60

Company had intended to implement in future periods. These costs had previously been recorded as construction-in-progress within property and equipment on the consolidated balance sheets.

During the year ended December 31, 2017, the Company determined that it had ceased receiving economic benefit from certain non-cancellable license and service contracts related to the New ERP.

Senior secured notes

On September 15, 2016, the Company issued $350.0 million of senior secured notes due 2024 (the “Senior Notes”) under an unregistered private placement not subject to the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”). The Senior Notes are governed by an indenture dated September 15, 2016 (the “Indenture”). The Senior Notes were issued by BMC East, LLC, a 100% owned subsidiary of the Company, and are guaranteed by the Company and the other subsidiaries that guarantee the Credit Agreement (as defined below). Each of the subsidiary guarantors is 100% owned, directly or indirectly, by the Company, and all guarantees are full and unconditional and joint and several. The Senior Notes mature on October 1, 2024 and are secured by a first priority lien on certain assets of the Company and a second priority lien on the collateral that secures the Credit Agreement on a first-priority basis, which collectively accounts for substantially all assets of the Company. The interest rate is fixed at 5.5% and is payable semiannually on April 1 and October 1.

The Indenture contains customary nonfinancial covenants, including restrictions on new indebtedness, issuance of liens and guarantees, investments, distributions to equityholders, asset sales and affiliate transactions. At any time prior to October 1, 2019, the Company may redeem the Senior Notes in whole or in part at a price equal to 100% of the principal, plus accrued and unpaid interest, plus the greater of (a) 1% of the principal amount of such Senior Note and (b) on any redemption date, the excess (to the extent positive) of the present value of the redemption price of such Senior Note at October 1, 2019 (equal to 104.125%) plus all required interest payments due on such Senior Note to and including October 1, 2019 (excluding accrued but unpaid interest), computed upon the redemption date using a discount rate equal to the applicable treasury rate, as defined in the Indenture, at such redemption date plus 50 basis points, over the outstanding principal amount of such Senior Note. Further, during any twelve month period prior to October 1, 2019, the Company may redeem up to 10% of the Senior Notes at a redemption price equal to 103% plus accrued and unpaid interest. At any time on or after October 1, 2019, the Company may redeem the Senior Notes in whole or in part at the redemption prices set forth in the Indenture plus accrued and unpaid interest. In addition, at any time prior to October 1, 2019, the Company may redeem up to 40% of the aggregate principal amount of the Senior Notes with the net cash proceeds of one or more equity offerings, as described in the Indenture, at a price equal to 105.5% plus accrued and unpaid interest. If the Company experiences certain change of control events, holders of the Senior Notes may require the Company to repurchase all or part of their Senior Notes at a price equal to 101% plus accrued and unpaid interest. The Company was in compliance with all debt covenants under the Indenture as of December 31, 2018.

The net cash proceeds from the Senior Notes were used to redeem in full $250.0 million of 9.0% senior secured notes that were issued by BMHC in September 2013 and which were scheduled to mature in September 2018 (the “Extinguished Senior Notes”), and to pay accrued interest on the Extinguished Senior Notes of $11.3 million. In connection with the redemption of the Extinguished Senior Notes, the Company incurred a loss on debt extinguishment of $12.5 million, consisting of a call premium of $8.4 million, and the write off of unamortized debt issuance costs and original issue discount of $4.1 million. The remaining proceeds were used to repay outstanding borrowings on the Revolver (as defined below) and to pay debt issuance costs of $6.7 million, which will be amortized over the term of the Senior Notes.

As of December 31, 2018, the estimated market value of the Senior Notes was $21.0 million lower than the carrying amount. The fair value is based on institutional trading activity and was classified as a Level 2 measurement in accordance with ASC 820.

Revolving credit agreement

On December 1, 2015, in connection with the Merger, the Company entered into a senior secured credit agreement with Wells Fargo Capital Finance, as administrative agent, and certain other lenders (the “Original Credit Agreement”) which includes a revolving line of credit (the “Revolver”). On September 15, 2016, the Company entered into the second amendment to the Credit Agreement (the “Second Amendment” and, the Original Credit Agreement as amended by the Second Amendment, the “Credit Agreement”), which reduced the aggregate commitment from $450.0 million to $375.0 million and increased the letters of credit commitment from $75.0 million to $100.0 million. The Revolver is subject to an asset-based borrowing formula on eligible accounts receivable, credit card receivables and inventory, in each case reduced by certain reserves.

Borrowings under the Revolver bear interest, at the Company’s option, at either the Base Rate (which means the higher of (i) the Federal Funds Rate plus 0.5%, (ii) the LIBOR rate plus 1.0% or (iii) the prime rate) plus a Base Rate Margin (which ranges from 0.25% to 0.75% based on Revolver availability) or LIBOR plus a LIBOR Rate Margin (which ranges from 1.25% to 1.75% based on Revolver availability).

The fee on any outstanding letters of credit issued under the Revolver ranges from 0.75% to 1.25%, depending on whether the letters of credit are fully cash collateralized. The fee on the unused portion of the Revolver is 0.25%. The Credit Agreement contains customary nonfinancial covenants, including restrictions on new indebtedness, issuance of liens, investments, distributions to equityholders, asset sales and affiliate transactions. The Credit Agreement includes a financial covenant that requires us to maintain a Fixed Charge Coverage Ratio, as defined therein, of at least 1.00:1:00, at the end of any fiscal quarter during the period from the date that Excess Availability, as defined therein, under the Credit Agreement is less than or equal to the greater of (1) $33.3 million and (2) 10% of the line cap, and remains in effect until excess availability has been greater than the greater of (1) $33.3 million and (2) 10% of the line cap for a period of at least 30 consecutive days.

The Revolver matures at the earlier of (i) December 1, 2020 and (ii) the date that is three months prior to the maturity of the Senior Notes, or if the Senior Notes are refinanced or repaid, the date that is three months prior to the new maturity date of the replacement notes or other indebtedness that replaced or refinanced the Senior Notes. Due to the redemption of the Extinguished Senior Notes during September 2016, the issuance of the Senior Notes which mature on October 1, 2024 and the Company entering into the Second Amendment, the effective maturity date of the Revolver was extended from June 15, 2018, the date three months prior to the maturity date of the Extinguished Senior Notes, to December 1, 2020. After considering the increase to the remaining term and the reduction of the aggregate commitment resulting from the Second Amendment, the overall borrowing capacity of the Revolver increased. Accordingly, all existing unamortized debt issuance costs and new debt issuance costs related to the Second Amendment are being amortized through December 1, 2020. The Company was in compliance with all debt covenants under the Credit Agreement as of December 31, 2018.

The Company had no outstanding borrowings under the Revolver with net availability of $309.5 million as of December 31, 2018. The Company had $61.0 million in letters of credit outstanding under the Credit Agreement as of December 31, 2018. Obligations under the Credit Agreement are guaranteed by the Company’s material subsidiaries. Obligations under the Credit Agreement and the guarantees of those obligations, are secured by substantially all of the Company’s assets and those of the guarantors, subject to certain exceptions and permitted liens, including a first-priority security interest in certain accounts receivable, inventory and certain other assets of the Company and a second-priority security interest in substantially all other assets of the Company that secure the Senior Notes on a first-priority basis.

On January 1, 2018, the Company adopted Topic 606 using the modified retrospective method applied to those contracts that were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with the Company’s historical accounting policy under Topic 605, Revenue Recognition.

The impact of adopting Topic 606 was not material to the Company’s results of operations for the year ended December 31, 2018 and as such, comparability between periods is not materially affected.

Beginning January 1, 2018, the Company has presented contract assets and contract liabilities on its consolidated balance sheets, determined on a contract-by-contract basis. Contract assets contain rights to payment that are conditional on something other than the passage of time, such as retainage, which were historically presented within accounts receivable, net of allowances, as well as the balances that were historically presented within costs in excess of billings on uncompleted contracts on the Company’s consolidated balance sheets. Contract liabilities contain advances from customers, which were historically presented within accrued expenses and other liabilities, as well as the balances that were historically presented within billings in excess of costs on uncompleted contracts on the Company’s consolidated balance sheets. Refer to further discussion of the Company’s contract assets and contract liabilities below.

Additionally, beginning January 1, 2018, the Company has presented a return asset, which represents inventory the Company expects to receive from customers related to estimated sales returns, within prepaid expenses and other current assets on the Company’s consolidated balance sheets. This balance was previously presented within inventories, net, on the Company’s consolidated balance sheets. Conversely, the Company has recorded a refund liability for estimated returns of inventory within accrued expenses and other liabilities on the Company’s consolidated balance sheets. These balances were previously presented as an allowance within accounts receivable, net of allowances, on the Company’s consolidated balance sheets.

The following table reflects the cumulative impact of adoption of Topic 606. As the cumulative impact of adopting Topic 606 on the Company’s historical results of operations was less than $0.1 million, the Company did not record an adjustment to opening retained earnings as of January 1, 2018.

Disaggregation of revenue

The following table presents the Company’s net sales disaggregated by customer type. See Note 15 to the consolidated financial statements for a disaggregation of the Company’s net sales by main product lines. As noted above, prior period amounts have not been adjusted under the modified retrospective method and continue to be reported in accordance with the Company’s historic accounting policy under Topic 605.

The following table reflects the Company’s estimate of net sales by each customer type for the years ended December 31, 2018, 2017 and 2016. Certain previously reported amounts for interim periods during the year ended December 31, 2018 and for the year ended December 31, 2017 were revised in the table below. The revisions were not material to the previously issued financial statements.

	Year Ended December 31,
(in thousands)	2018		2017		2016
Single-family homebuilders	$	2,814,100	$	2,526,837	$	2,262,124
Remodeling contractors	427,346		380,460		371,018
Multi-family, commercial & other contractors	441,002		458,671		460,601
Total net sales	$	3,682,448	$	3,365,968	$	3,093,743

Contract balances

The following table reflects the Company’s contract balances as of December 31, 2018 and January 1, 2018, the date that the Company adopted Topic 606:

(in thousands)	December 31, 2018		January 1, 2018		Change
Receivables, including unbilled receivables presented in prepaid expenses and other current assets	$	306,370	$	321,418	$	(15,048	)
Contract assets	32,348		38,557		(6,209		)
Contract liabilities	$	34,888	$	26,330	$	8,558

During the year ended December 31, 2018, the Company’s contract assets decreased by $6.2 million and the Company’s contract liabilities increased by $8.6 million. The change in contract assets and liabilities was primarily due to the timing of revenue recognition, as the balances were not materially impacted by any other factors. For the year ended December 31, 2018, the Company recognized revenue of $25.1 million, that was included in contract liabilities as of January 1, 2018. Revenue recognized related to performance obligations that were satisfied or partially satisfied in previous periods was not material for the year ended December 31, 2018.

Practical expedients

As permitted by Topic 606, the Company has elected to expense any incremental costs of obtaining a contract as incurred as the amortization period would have been one year or less. Additionally, as permitted by Topic 606, the Company has elected not to adjust the promised amount of consideration for a significant financing component as the Company expects that the period of time between the Company’s satisfaction of the performance obligation and the customer’s payment would have been one year or less. Finally, as permitted by Topic 606, the Company has elected not to disclose the value of unsatisfied performance obligations, as the Company’s contracts generally have an original expected length of one year or less.

A reconciliation of differences between the statutory U.S. federal income tax rate and the Company’s effective tax rate from continuing operations for the years ended December 31, 2018, 2017 and 2016 follows:

	2018		2017		2016
Federal statutory rate	21.0	%	35.0	%	35.0	%
State taxes, net of federal tax	2.6		2.9		2.7

Other items	—		(0.2	)	0.5
Effective tax rate	23.7	%	29.8	%	31.6	%

On December 22, 2017, the 2017 Tax Act was enacted, which significantly changed U.S. tax law effective January 1, 2018 by, among other things, lowering corporate income tax rates from 35% to 21%, eliminating Internal Revenue Code (“IRC”) Section 199 manufacturing deduction, accelerating tax depreciation on certain acquired assets, further limiting executive compensation, and creating certain interest deduction limitations. The Securities and Exchange Commission staff issued Staff Accounting Bulletin No. 118 to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the 2017 Tax Act. The Company recognized a net tax benefit of $3.6 million during the year ended December 31, 2017 related to the impact of the 2017 Tax Act for the remeasurement of deferred tax assets and liabilities. During the year ended December 31, 2018, the Company completed its accounting for the income tax effects of the 2017 Tax Act within the measurement period as provided under SEC Staff Accounting Bulletin No. 118, which resulted in recognizing an additional tax benefit of $0.5 million.

For the year ended December 31, 2018, the Company recognized $37.2 million of income tax expense, which included an income tax benefit of $0.5 million related to the 2017 Tax Act. The Company’s effective tax rate for the year ended December 31, 2018 was higher than the Company’s federal and state statutory rates primarily due to nondeductible expenses.

For the year ended December 31, 2017, the Company recognized $24.4 million of income tax expense, which included an income tax benefit of $3.6 million related to the 2017 Tax Act. The Company’s effective tax rate for the year ended December 31, 2017 was lower than the federal and state statutory rates primarily due to the effects of the 2017 Tax Act, an IRC Section 199 manufacturing deduction and excess windfall tax benefits of stock compensation deductions.

68

For the year ended December 31, 2016, the Company recognized $14.3 million of income tax expense, which included an income tax benefit of $1.7 million as a result of the Company adopting a state tax position related to IRC section 382 limitations on a state net operating loss carry-forward. For the year ended December 31, 2016, the Company’s effective tax rate, excluding the state tax position change, was lower than the Company’s federal and state statutory rates primarily due to excess windfall tax benefits of stock compensation deductions and an IRC section 199 manufacturing deduction.

Significant components of the Company’s deferred tax assets and liabilities are as follows at December 31, 2018 and 2017:

(in thousands)	2018			2017
Deferred tax assets related to:
Accounts receivable	$	2,278		$	2,061
Inventory	2,631			1,931
Accrued compensation	6,783			2,981

Net deferred tax liability	$	(3,034	)	$	(1,768	)

As of December 31, 2018, due to IRC section 382 limitations, the Company estimates federal net operating loss carryforwards generated prior to November 2011 will be limited to approximately $4.8 million per year through 2034. These net operating losses may generally be carried forward 20 years. As a result, federal operating losses if unused will expire as follows:

• $29.4 million in 2028;

• $17.3 million in 2029; and

• $31.2 million in years 2030 through 2034.

In addition, as of December 31, 2018, the Company had $75.1 million of state net operating loss carryforwards that expire at various dates commencing in 2022 through 2035.

The Company recognized tax benefits of $0.3 million and $1.9 million during 2018 and 2017, respectively, from stock-based compensation deductions into its income tax expense. Deferred tax assets relating to tax benefits of stock-based compensation were reduced to reflect exercises or vesting; however, some exercises or vesting resulted in tax deductions in excess of previously recorded deferred tax benefits (“windfalls”). Prior to the adoption of ASU 2016-09, Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, windfall tax benefits were recognized as a component of shareholders’ equity, which included $0.4 million for December 31, 2016.

The Company recognized a current income tax payable of $0.9 million and an income tax receivable of $3.7 million as of December 31, 2018 and 2017, respectively. The Company paid federal and state income tax payments of $34.2 million and $23.5 million during 2018 and 2017, respectively. The Company received tax refunds of $2.9 million and $0.6 million in 2018 and 2017, respectively.

69

In accordance with ASC 740, the Company evaluates its deferred tax assets to determine if valuation allowances are required. In assessing the realizability of deferred tax assets, the Company considers both positive and negative evidence in determining whether it is more likely than not that some portion or all of the deferred tax assets will not be realized.

As of December 31, 2018 and 2017, the primary positive evidence considered to support the realization of the Company’s deferred tax assets includes: (i) the cumulative pre-tax income over the last 36 months, (ii) the reversal of deferred tax liabilities related to depreciation and amortization that would occur within the same jurisdiction and during the carry forward period necessary to absorb the federal and state net operating losses and other deferred tax assets, (iii) current and prior year utilization of federal and state net operating losses, and (iv) no history of material expiring tax attributes. The primary negative evidence considered includes: (i) the Company’s cumulative losses prior to 2013, (ii) unsettled circumstances associated with the general economy and housing market, as well as mortgage credit availability, and (iii) no federal and state net operating loss carryback opportunities. To the extent the Company generates future net operating losses, the Company may be required to increase the valuation allowance on its deferred tax assets and income tax benefit would be adversely affected.

Based upon the positive and negative evidence considered, the Company believes it is more likely than not that it will realize the benefit of the deferred tax assets, net of the existing state tax valuation allowances of $0.1 million as of December 31, 2018 and 2017. To the extent the Company generates sufficient taxable income in the future to fully utilize the tax benefits of the net deferred tax assets on which a valuation allowance was recorded, the Company’s effective tax rate would be impacted as the valuation allowance is reversed. The Company continues to evaluate its deferred tax asset on a quarterly basis and notes that, if economic conditions were to change such that the Company earns less taxable income than the amounts required to fully utilize its deferred tax asset, a portion of the asset may expire unused.

The following table shows the changes in the amount of the Company’s valuation allowance:

(in thousands)	2018		2017		2016
Balance at January 1,	$	145	$	125	$	126
Additions charged to expense	—		20		—
Additions charged to Goodwill/Purchase Accounting	—		—		—
Deductions - other	—		—		(1		)
Balance at December 31,	$	145	$	145	$	125

The Company has no material uncertain tax positions as of December 31, 2018 and 2017.

The Company’s state tax returns are open to examination for an average of three years. However, certain jurisdictions remain open to examination longer than three years due to the existence of net operating losses. The Company’s federal returns are open to examination for three years; however, due to statutory waivers, SBS’ tax years ended July 31, 2008 and May 5, 2009 remain open until July 31, 2020 with the federal tax authorities. SBS is currently under examination by the IRS for its tax years ended July 31, 2008 and May 5, 2009. At December 31, 2018 and 2017, the amount recognized related to expected tax, penalties and interest payments as a result of the IRS audits in income taxes payable and income taxes receivable, respectively, on the consolidated balance sheets was immaterial.

The Company’s policy is to recognize interest and penalties related to income tax liabilities and unrecognized tax benefits in income tax expense. During the years ended December 31, 2018, 2017 and 2016, penalties and interest related to income tax liabilities and uncertain tax benefits were not material.

13.    Commitments and Contingencies

The Company is obligated under capital leases covering fleet vehicles and certain equipment, as well as certain facilities. The fleet vehicles and equipment leases generally have terms ranging from three to six years and the facility leases have a remaining term of four to five years. The carrying value of property and equipment under capital leases was $17.2 million and $25.2 million at December 31, 2018 and 2017, respectively, net of accumulated depreciation of $42.5 million and $37.1 million, respectively. Amortization of assets held under capital leases is included within depreciation expense or cost of goods sold on the consolidated statements of operations.

70

The Company also has noncancelable operating leases, primarily for buildings, improvements and equipment. These leases generally contain renewal options for periods ranging from one to five years and may require the Company to pay executory costs such as property taxes, maintenance and insurance.

Future minimum lease payments under noncancelable operating leases (with initial or remaining lease terms in excess of one year) and future minimum capital lease payments as of December 31, 2018 are as follows:

(in thousands)	Capital Leases			Operating Leases
2019	$	7,245		$	30,431
2020	5,599			24,210
2021	2,356			21,551

Total obligation under capital leases	15,506
Less: Current portion of capital lease obligation	(6,661		)
Long-term capital lease obligation	$	8,845

(a) Minimum operating lease payments have not been reduced by minimum sublease rentals of $0.1 million due in the future under noncancelable subleases.    

Total rent expense under operating leases, excluding short-term rentals, for the years ended December 31, 2018, 2017 and 2016 was $32.2 million, $30.5 million and $29.3 million, respectively, which are included in either cost of sales or selling, general and administrative expenses on the consolidated statements of operations, depending on the type of operations undertaken by the related facility or asset. Future payments for certain leases will be adjusted based on increases in the consumer price index.

As of December 31, 2018, the Company had purchase commitments totaling $31.6 million related primarily to vehicles and certain IT equipment, which are enforceable and legally binding on the Company.

From time to time, various claims, legal proceedings and litigation are asserted or commenced against the Company principally arising from alleged product liability, warranty, casualty, construction defect, contract, tort, employment and other disputes. In determining loss contingencies, management considers the likelihood of loss as well as the ability to reasonably estimate the amount of such loss or liability. An estimated loss is recorded when it is considered probable that such a liability has been incurred and when the amount of loss can be reasonably estimated. It is not certain that the Company will prevail in these matters. However, the Company does not believe that the ultimate outcome of any pending matters will have a material adverse effect on its consolidated financial position, results of operations or cash flows. As of December 31, 2018 and 2017, the Company has accrued $3.0 million in relation to pending litigation that was recorded within selling, general and administrative expenses in its statements of operations during the year ended December 31, 2017.

14.    Stock Based Compensation

Long-term incentive plan

In connection with its initial public offering in August 2013, SBS adopted the Stock Building Supply Holdings, Inc. 2013 Incentive Compensation Plan (“SBS 2013 Incentive Plan”). The SBS 2013 Incentive Plan provides for grants of stock options, stock appreciation rights, restricted stock, other stock-based awards, other cash-based compensation and performance awards. In general, if awards under the SBS 2013 Incentive Plan are for any reason canceled, or expire or terminate unexercised, the shares covered by such awards may again be available for the grant of awards under the SBS 2013 Incentive Plan. Awards granted under the SBS 2013 Incentive Plan generally vest over a period of three or four years. Stock options granted under the SBS 2013 Incentive Plan have a maximum contractual term of 10 years from the date of grant. As of December 31, 2018, 2.4 million shares were available for issuance under the SBS 2013 Incentive Plan.

71

Performance-based restricted stock units

As of December 31, 2018, the Company has performance-based restricted stock units outstanding that were granted during the years ended December 31, 2018 and 2017. The total number of performance-based restricted stock units that could be issued upon future vestings ranges from zero to a maximum of 0.6 million, based 50% upon the Company’s average return on invested capital and 50% upon the Company’s cumulative adjusted earnings per share over three year performance periods. Compensation cost for the performance-based restricted stock units is recorded based on the expected number of units that will vest and is adjusted, as appropriate, throughout the performance period.

Stock based compensation expense

Stock based compensation is included in selling, general and administrative expenses on the consolidated statements of operations. The following table highlights stock based compensation for the years ended December 31, 2018, 2017 and 2016:

ASC 280, Segment Reporting (“ASC 280”) defines operating segments as components of an enterprise about which separate financial information is available that is evaluated regularly by the CODM in deciding how to allocate resources and in assessing performance.

The Company’s five operating segments are the Mid-Atlantic, Southeast, Texas, Intermountain and Western divisions. The CODM reviews aggregate information to allocate resources and assess performance. Based on the CODM’s review, as well as the similar economic characteristics, nature of products, distribution methods and customers of the divisions, the Company has aggregated its operating segments into one reportable segment, “Geographic divisions.”

In addition to the Company’s reportable segment, the Company’s consolidated results include “Other reconciling items.” Other reconciling items comprises the Company’s corporate activities and other income and expenses not allocated to the operating segments.

The following tables present Net sales, Adjusted EBITDA and certain other measures for the reportable segment and total Company operations for the periods indicated. Adjusted EBITDA is used as a performance metric by the CODM in determining how to allocate resources and assess performance.

16.    Earnings Per Share

Basic net income per share (“EPS”) is calculated by dividing net income attributable to common stockholders by the weighted average shares outstanding during the period. Diluted EPS is calculated by adjusting weighted average shares outstanding for the dilutive effect of potential common shares, determined using the treasury-stock method. For purposes of the diluted EPS calculation, stock options, restricted stock and restricted stock unit awards are considered to be potential common shares. Performance-based restricted stock units are not included in the calculation of diluted EPS until they are contingently issuable.

The basic and diluted EPS calculations for the years ended December 31, 2018, 2017 and 2016 are presented below:

	Year Ended December 31,
(in thousands, except per share amounts)	2018		2017		2016
Income attributable to common stockholders	$	119,738	$	57,425	$	30,880
Weighted average common shares outstanding, basic	67,273		66,900		66,055
Effect of dilutive securities:
Restricted stock units	324		235		129
Stock options	135		204		218
Restricted stock	16		65		207
Weighted average common shares outstanding, diluted	67,748		67,404		66,609
Basic income per common share	$	1.78	$	0.86	$	0.47
Diluted income per common share	$	1.77	$	0.85	$	0.46

The following table provides the securities that could potentially dilute EPS in the future, but were not included in the computation of diluted EPS for the periods presented because to do so would have been anti-dilutive. The amounts included in this table exclude performance-based restricted stock units. As of December 31, 2018, the number of currently outstanding performance-based restricted stock units that are issued upon vesting could range from zero to a maximum of 0.6 million.

18.    Subsequent Events

On January 14, 2019, the Company acquired substantially all of the assets and assumed certain liabilities of Barefoot, a supplier of windows, exterior doors, hardware, specialty products and installation services in the Charlotte, North Carolina metropolitan area. On February 8, 2019, the Company acquired substantially all of the assets and assumed certain liabilities of Locust Lumber, a supplier of lumber products and building materials primarily to custom homebuilders and professional remodeling contractors in the Charlotte, North Carolina metropolitan area. These acquisitions enhance the Company’s value-added offerings and footprint in the Charlotte, North Carolina metropolitan area. The preliminary purchase price, in aggregate, for these acquisitions was $54.5 million, which includes an initial holdback of $2.5 million due to the sellers of Barefoot one year from the closing date. The holdback amount may be reduced under certain circumstances. The Company funded the transactions through available cash. For the year ended December 31, 2018, Barefoot and Locust Lumber generated net sales, in aggregate, of approximately $105 million.

The results of operations of Barefoot and Locust Lumber will be included in the Company’s consolidated financial statements beginning on the respective acquisition dates. Due to the timing of the close of the acquisitions, the initial purchase accounting for the acquisitions is not complete and therefore, certain disclosures required by ASC 805 have not been included. The Company is in the process of performing its valuation of the acquired assets and liabilities and currently anticipates customer relationship intangible assets and goodwill, among other operating assets and liabilities, to be recognized as part of these acquisitions.

Item 9A.    Controls and Procedures

Disclosure controls and procedures

Our management is responsible for establishing and maintaining disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). These disclosure controls and procedures are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is accumulated and communicated to the issuer’s management, including its principal executive officer and principal financial officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

We have evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report, with the participation of our Chief Executive Officer and Chief Financial Officer, as well as other key members of our management. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of December 31, 2018.

The design of any system of control is based upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated objectives under all future events, no matter how remote, or that the degree of compliance with the policies or procedures may not deteriorate. Because of their inherent limitations, disclosure controls and procedures may not prevent or detect all misstatements. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives.

Management’s annual report on internal control over financial reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act). Management, with the participation of our principal executive officer and principal financial officer, conducted an assessment of the effectiveness of our internal control over financial reporting based on the criteria set forth in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Based on the assessment, management has concluded that the internal control over financial reporting of BMC Stock Holdings, Inc. was effective as of December 31, 2018 to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with GAAP.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our independent registered public accounting firm, PricewaterhouseCoopers LLP, has issued an audit report with respect to the effectiveness of our internal control over financial reporting as of December 31, 2018, which appears in Part II, Item 8 of this Annual Report on Form 10-K.

Changes in internal control over financial reporting

There was no change in our internal control over financial reporting during the three months ended December 31, 2018 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

EMPLOYMENT AGREEMENT

This EMPLOYMENT AGREEMENT (this “Agreement”) is entered into as of January 7, 2019 between Timothy Johnson (“Executive”) and BMC STOCK HOLDINGS, INC., a Delaware corporation (the “Company”).

RECITALS

WHEREAS, Executive and the Company desire to enter into an Employment Agreement setting forth the terms and conditions of Executive’s employment by the Company.

NOW, THEREFORE, in consideration of the promises and mutual covenants contained herein, the Company and Executive hereby agree as follows:

TERMS AND CONDITIONS

SECTION 1
EMPLOYMENT

1.1Employment. The Company hereby employs Executive and Executive hereby accepts such employment by the Company as of the Effective Date for the period and upon the terms and conditions contained in this Agreement.

1.2Position and Duties. Executive shall serve the Company effective as of the date of this Agreement as Executive Vice President, General Counsel and Corporate Secretary. Executive shall have all of the powers and duties in such capacity that are customary to the powers and duties of those of a Executive Vice President and General Counsel serving in a similar role in a company within the industry in which the Company operates. The foregoing powers and duties shall be subject to the direction of the Company’s Board of Directors (the “Board”) and its President and Chief Executive Officer. Executive shall report to the President and Chief Executive Officer of the Company. Executive shall devote Executive’s full business time and attention and full diligence and vigor and good faith efforts to the affairs of the Company and Executive shall not engage in any other material business duties or pursuits or render any services of a professional nature to any other entity or person, or serve on any other board of directors (other than a not-for-profit board of directors, and then only to the extent it does not interfere with his duties to the Company), without the prior written consent of the Chief Executive Officer and the Board.

1.3Effective Date; Indefinite Term. Executive’s employment under this Agreement shall begin on the latest of the mutual execution of this Agreement, the effective date mutually agreed to by the Company and the Executive, and the date this Agreement is approved by the Company’s Board of Directors (“Effective Date”) and shall continue for an indefinite term, until terminated in accordance with SECTION 3 below. Certain provisions, however, as more fully set forth in SECTION 4, SECTION 5 and SECTION 6 below, continue in effect beyond the date of the termination of Executive’s employment (the “Termination Date”).

SECTION 2
COMPENSATION AND BENEFITS

2.1Compensation.

(a)Base Salary. The Company shall pay to Executive an annual base salary at the rate not less than $325,000 each calendar year (“Base Salary”), payable in accordance with the Company’s ordinary payroll and withholding practices from time to time in effect for its employees. During the term of employment hereunder, the Executive’s salary shall be reviewed from time to time (but no less than annually) to determine whether an increase in Executive’s salary is appropriate. Any such increase shall be at the sole discretion of the Board.

(b)Annual Cash Bonus. During the term of employment, Executive shall be eligible for an annual cash bonus under the Company’s Annual Incentive Plan (“AIP”) as from time to time amended or adopted by the Board. The Executive’s annual Target Bonus shall be equal to 75 percent of his annual base salary paid. Actual bonuses earned may range from zero to two times the Target Bonus depending upon Company and individual performance relative to goals and funding formulas established annually by the Board or the Compensation Committee (the “Committee”) of the Board.

(c)Long-Term Incentive Awards. During the term of employment, Executive shall be eligible to receive long-term incentive awards (equity or cash) under the Company’s Long-Term Incentive Plan (“LTIP”). Awards under the LTIP, and their terms and conditions, are determined by the Board or the Committee, as appropriate, based upon any of the factors described in the LTIP in addition to any other factors the Board or Committee deems appropriate to consider.

2.2Benefits.

(a)Generally. Executive shall be eligible to participate, to the extent it is legal and permitted by the applicable benefits plans, policies or contracts, in all employee benefits programs that the Company may adopt for its employees generally providing for sick or other leave, vacation, group health, disability and life insurance benefits. Executive shall be eligible to participate in the Company’s 401(k) plan on the terms and conditions and qualifications of such plan. Executive shall be entitled to four (4) weeks of paid vacation for each full calendar year of employment, to be accrued in accordance with the Company’s regular vacation pay policy.

2.3Expense Reimbursement. The Company shall reimburse Executive for all reasonable expenses incurred in connection with performing his duties upon presentation of documents in accordance with the reasonable procedures established by the Company.

SECTION 3
TERMINATION

3.1By the Company:

(a)For Cause. The Company shall have the right at any time, exercisable upon written notice, to terminate the Executive’s employment for Cause. As used in this Agreement, “Cause” shall mean that the Executive:

2

(i)has committed any act or omission that results in, or that may reasonably be expected to result in, a conviction, plea of no contest or imposition of unadjudicated probation for any felony or crime involving moral turpitude;

(ii)has committed any act of fraud, embezzlement or misappropriation, or engaged in material misconduct or breach of fiduciary duty against the Company (or any predecessor thereto or successor thereof);

(iii)has willfully failed to substantially perform such duties as are reasonably assigned to him under this Agreement; or

(iv)has unlawfully used (including being under the influence) or possessed illegal drugs;

(v)fails to attempt in good faith to comply with a lawful directive of the CEO or the Board that is consistent with the Company’s business practices and Code of Ethics;

(vi)engages in (A) willful misconduct for which Executive receives an improper personal benefit at the expense of the Company, or (B) accidental misconduct resulting in such a benefit which Executive does not promptly report to the Company and redress promptly upon becoming aware of such benefit;

(vii)in carrying out his duties under this Agreement, has engaged in acts or omissions constituting gross negligence or willful misconduct resulting in, or which, in the good faith opinion of the Board, could be expected to result in, substantial economic harm to the Company;

(viii)has failed for any reason to correct, cease or alter any action or omission that (A) violates or does not conform with the Company’s policies, standards or regulations in a material way, (B) constitutes a material breach of this Agreement, including SECTION 4, or (C) constitutes a material breach of his duty of loyalty to the Company; or

(ix)has disclosed any Proprietary Information (as defined below) without authorization from the Board, Chief Executive Officer or Chief Operating Officer except as otherwise permitted by this Agreement, another agreement between the parties or any Company policy in effect at the time of disclosure.

For purposes of the definition of “Cause”, “Company” shall include any subsidiary, business unit or affiliate of the Company. The Company shall provide written notice to Executive of any act or omission that the Company believes constitutes grounds for “Cause” pursuant to clause (iii), (v) (viii)(B), (viii) or (ix) above, and no such act or omission shall constitute “Cause” unless Executive fails to remedy such act or omission within ten (10) days of the receipt of such notice; provided that such ten (10) day cure period shall not apply with respect to any matter that is incapable of cure within such period.

3

(b)Due to Death or Disability. Executive’s employment shall terminate upon Executive’s death and the Company may terminate Executive’s employment due to Executive’s Disability. As used in this Agreement, “Disability” shall mean any physical or mental disability or incapacity that is reasonably expected to render Executive incapable of fully performing the services required of Executive by the Company for a period of 180 consecutive days or for shorter periods aggregating 180 days during any twelve (12) month period. For purposes of the definition of “Disability”, “Company” shall include any subsidiary, business unit or affiliate of the Company. Any question as to the existence of a Disability upon which Executive and the Company cannot agree shall be determined by a qualified independent physician selected by the Company, with the consent of the Executive, which consent shall not be unreasonably withheld. The determination of such physician made in writing to the Company and Executive shall be final and conclusive for all purposes of determining Disability under this Agreement.

(c)Without Cause. The Company may terminate Executive’s employment under this Agreement at any time Without Cause. As used in this Agreement, a termination “Without Cause” shall mean the termination of Executive’s employment by the Company other than (i) for Cause pursuant to SECTION 3.l(a) above or (ii) due to death or Disability pursuant to SECTION 3.1(b) above.

3.2By the Executive:

(a)Without Good Reason. Executive may terminate his employment under this Agreement at any time Without Good Reason. As used in this Agreement, a termination “Without Good Reason” shall mean termination of Executive’s employment by Executive other than For Good Reason pursuant to SECTION 3.2(b) below.

(b)For Good Reason. Executive shall have the right at any time to resign his employment under this Agreement For Good Reason. As usedin this Agreement, “For Good Reason” shall mean any of the following: (i) a material diminutionintheExecutive’sBase Salary or Target Annual Cash Bonus, (ii) a material diminution in Executive’s title, authority, duties and responsibilities as compared to Executive’s title, authority, duties and responsibilities measured immediately after the Effective Date, (iii) any requirement that the Executive report to anyone but (A) the President and Chief Executive Officer of the ultimate parent entity, or (B) if the Company becomes a subsidiary or a division of another entity not engaged predominantly in the same business as the Company, the most senior executive or operating officer of such subsidiary or division, (iv) any material breach by the Company or related entities of this Agreement or the Executive’s other agreements with the Company or related entities, (v) there is a Change in Control and the successor to the Company, if applicable, does not assume and continue this Agreement, and (vi) any requirement by the Company that the Executive relocate his personal residence to any city more than fifty (50) miles from Raleigh, North Carolina.

Notwithstanding the foregoing, no event shall be a Good Reason event unless (i) the Executive gives the Company written notice that he is resigning for Good Reason within ninety (30) days of the first occurrence of the Good Reason event, and (ii) the Company (A) accepts such resignation, (B) does not cure such Good Reason event, or (C) disputes the existence of Good Reason, in each case within thirty (30) days of receiving such notice, and in the case of clauses (A) and (B) the Executive’s resignation for Good Reason shall become effective as of the earlier of (x) the date the

4

Company accepts such resignation, or (y) the expiration of the thirty day cure period (provided the Company has not cured the Good Reason event) and in the case of clause (C) shall become effective only if Good Reason is ultimately determined to exist upon final resolution of the Company’s dispute of his resignation by a court of competent jurisdiction or otherwise.

3.3Compensation Upon Termination. Upon termination of Executive’s employment with the Company, the Company’s obligationtopaycompensationandbenefits under SECTION 2 hereof shall terminate, except that the Company shall pay to the Executive or, if applicable, the Executive’s heirs, all earned but unpaid BaseSalary under SECTION 2.1(a) and accrued but unused vacation under SECTION 2.2, in each case, through the Termination Date. In addition, Executive shall be entitled to receive (i) any vested amounts or benefits due under any tax-qualified retirement or group insurance plan or program in accordance with the terms thereof, and (ii) other than on termination for Cause or a voluntary termination by Executive without Good Reason, his Annual Cash Bonus for any completed fiscal year to the extent earned for such fiscal year and if such bonus has not previously been paid for such completed fiscal year, at the same time such Annual Cash Bonus would have been paid if Executive had continued in employment (it being understood that in the event of any such termination Executive is not entitled to an Annual Bonus for the then-current Fiscal Year). If the Company terminates Executive’s employment Without Cause, for Executive’s death, for Executive’s Disability, or if Executive terminates his employment for Good Reason, then, in addition, to the foregoing compensation, upon execution and delivery (and non-revocation) by Executive of the Separation Agreement and General Release as set forth in SECTION 6.10, the Company shall pay severance benefits pursuant to SECTION 3.4 below. In the event of Executive’s death or Executive’s Disability, if Executive is unable to execute and deliver such Separation Agreement and General Release, execution and delivery may be completed by Executive’s spouse, if available, or if such spouse is unavailable due to death or incapacity, any other adult member of Executive’s immediate family. No other payments or compensation of any kind shall be paid in respect of Executive’s employment with or termination from the Company. Notwithstanding any contrary provision contained herein, in the event of any termination of Executive’s employment, the exclusive remedies available to the Executive shall be the amounts due under this SECTION 3, which are in the nature of liquidated damages, and are not in the nature of a penalty.

3.4Severance Benefits.

(a)Termination without Cause or for Good Reason. Subject to the terms andconditions of eligibility for Executive’s receipt of severance benefits under this Agreement, including the timely execution and delivery (and non-revocation) by Executive of the Separation Agreement and General Release as set forth in SECTION 6.10, the Company shall pay to Executive, as severance benefits, which amounts are in addition to the Compensation upon Termination set forth in SECTION 3.3 herein:

(i)An amount equal to his current annualized Base Salary which shall be paid to Executive on a salary continuation basis according to the Company’s normal payroll practices over the 12 month period following the date the Executive incurs a Separation from Service, but in no event less frequently than monthly.

5

(ii)An amount equal to the Executive's Target Bonus referenced in SECTION 2.1(b) (based upon his Base Salary as of the date of termination) which shall be paid to Executive when the Annual Cash Bonus for such year is paid to other executives of the Company.

(iii)Subject to (1) the Executive’s timely election of continuation coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), and (2) the Executive’s continued copayment of premiums at the same level and cost to the Executive as if the Executive were an employee of the Company (excluding, for purposes of calculating cost, an employee’s ability to pay premiums with pre-tax dollars), continued participation in the Company’s group health plan (to the extent permitted under applicable law and the terms of such plan) which covers the Executive (and the Executive’s eligible dependents) for a period of twelve (12) months at the Company’s expense, provided that the Executive is eligible and remains eligible for COBRA coverage. The Company may modify its obligation under this SECTION 3.4(a)(ii) to the extent reasonably necessary to avoid any penalty or excise taxes imposed on it in connection with the continued payment of premiums by the Company under the Patient Protection and Affordable Care Act of 2010, as amended.

(iv)The Company shall accelerate the vesting of the Executive’s time-based and then-outstanding and unvested stock options, stock appreciation rights, restricted stock units or shares, or any other Company time-based equity compensation awards, to the extent that such awards would have vested solely upon the Executive’s continued employment within twelve months following the date of termination.

(v)In addition to the benefits described in SECTION 3.4(a)(i), (ii) and (iii), in the event that there is a Change in Control of the Company and (1) the successor fails to assume and continue this Agreement, or (2) within ninety (90) days preceding or within six (6) months after the Change in Control (a) the Executive is terminated without Cause, or (b) Executive terminates for Good Reason, the Company shall (I) accelerate the vesting of (x) the Executive’s then-outstanding and unvested stock options, stock appreciation rights, restricted stock units or shares, or any other Company time-based equity compensation awards, to the extent that such awards would have vested solely upon the Executive’s continued employment, such that one hundred percent (100%) of such awards become vested in full and (y) the target level of the Executive’s then-outstanding performance stock units or other Company equity compensation awards that vest based on achievement of specified performance criteria, such that such awards become fully vested at the target level of award, (II) continue Executive’s Base Salary, as provided under SECTION 3.4(i) for 24 months rather than 12 months, and (III)  pay Executive an amount equal to the Executive’s Target Bonus (under SECTION 2.1 (b), based upon his Base Salary as of the date of termination), which amount shall be paid to Executive when the Company pays the Annual Cash Bonus for the calendar year that commences immediately after Executive’s termination (and for clarity, shall be in addition to the Target Bonus paid to Executive under SECTION 3.4(ii) – such that Executive receives two Target Bonuses), and (IV) Provide the COBRA subsidy as described in Section 3.4(iii) above for 18 months.

6

(b)Termination for Executive’s Death or Disability. In the event of Executive’s death or Disability, the Company shall accelerate the vesting of the Executive’s then-outstanding and unvested stock options, stock appreciation rights, restricted stock units or shares, or any other Company time-based equity compensation awards, to the extent that such awards would have vested solely upon the Executive’s continued employment within twelve months following the date of termination.

(c)Notwithstanding any other provision of this Agreement, any severance benefits that would otherwise have been paid before the Company’s first normal payroll payment date falling on or after the sixtieth (60th) day after the date on which the Executive incurs a Separation from Service (the “First Payment Date”) shall be made on the First Payment Date. Each separate severance installment payment and each other payment that Executive may be eligible to receive under this Agreement shall be a separate payment under this Agreement for all purposes.

(d)Notwithstanding anything to the contrary in this Agreement, with respect to any severance benefits or amounts payable to the Executive under this Agreement, in no event shall a termination of employment occur under this Agreement unless such termination constitutes a Separation from Service. For purposes of this Agreement, a “Separation from Service” shall mean the Executive’s “separation from service” with the Company as such term is defined in Treasury Regulation Section 1.409A-1(h) and any successor provision thereto.

Notwithstanding anything to the contrary in this Agreement, to the maximum extent permitted by applicable law, amounts payable to the Executive pursuant to this SECTION 3.4 shall be made in reliance upon Treas. Reg. Section 1.409A-1(b)(9) (Separation Pay Plans) or Treas. Reg. Section 1.409A-l(b)(4) (Short-Term Deferrals). However, to the extent any such payments are treated as non-qualified deferred compensation subject to Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), then if Executive is deemed at the time of his Separation from Service to be a “specified employee” for purposes of Section 409A(a)(2)(B)(i) of the Code, then to the extent delayed commencement of any portion of the benefits to which the Executive is entitled under this Agreement is required in order to avoid a prohibited distribution under Section 409A(a)(2)(B)(i) of the Code, such portion of the Executive’s termination benefits shall not be provided to the Executive prior to the earlier of (i) the expiration of the six-month period measured from the date of the Executive’s Separation from Service or (ii) the date of Executive’s death. Upon the earlier of such dates, all payments deferred pursuant to this SECTION 3.4(d) shall be paid in a lump sum to the Executive. Thereafter, payments will resume in accordance with this Agreement. The determination of whether the Executive is a “specified employee” for purposes of Section 409A(a)(2)(B)(i) of the Code as of the time of his Separation from Service shall be made by the Company in accordance with the terms of Section 409A of the Code and applicable guidance thereunder (including without limitation Treas. Reg. Section 1.409A-l(i) and any successor provision thereto).

(e)The Executive shall have no duty or obligation to mitigate the amounts due under SECTION 3.4(a) above and any amounts earned by Executive from other employment shall not be offset or reduce the amounts due hereunder.

(f)The term “Change in Control” shall mean the occurrence of any of the following events: (i) the Board approves a plan of liquidation, dissolution or winding-up of the

7

Company, (ii) the consummation of a sale or other disposition of all or substantially all of the assets of the Company and its subsidiaries, (iii) any “person,” as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (other than the Company, any trustee or other fiduciary holding securities under any employee benefit plan of the Company, or any company owned, directly or indirectly, by the stockholders of the Company in substantially the same proportions as their ownership of Common Stock of the Company), becoming the beneficial owner (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing more than 50% of the combined voting power of the Company’s then outstanding securities or otherwise acquiring the power to elect or designate a majority of the members of the Board, (iv) a merger or consolidation of the Company with any other corporation or entity (a “Merger Partner”), as a result of which (A) the voting securities of the Merger Partner outstanding immediately prior thereto represent (either by remaining outstanding or by being converted into voting securities of a surviving entity) more than 50% of the combined voting power of the voting securities of the Company or such surviving entity outstanding immediately after such merger or consolidation, or (B) the shareholders of the Merger Partner immediately prior thereto have the power to elect or designate a majority of the members of the Board of the Company or such surviving entity; provided, however, that a merger or consolidation effected to implement a recapitalization of the Company (or similar transaction) in which no person (other than those covered by the exceptions in clause (iii) above) acquires more than 50% of the combined voting power of the Company’s then outstanding securities or the power to elect or designate a majority of the members of the Board shall not constitute a Change in Control of the Company.

8

SECTION 4
CERTAIN AGREEMENTS

4.1Confidentiality. Executive acknowledges that the Company owns and shall own and has developed and shall develop proprietary information concerning its business and the business of its subsidiaries and affiliates and each of their employees, customers and clients (“Proprietary Information”). Such Proprietary Information includes, among other things, trade secrets, financial information, product plans, customer lists, marketing plans, systems, manuals, training materials, forecasts, inventions, improvements, know-how and other intellectual property, in each case, relating to the Company’s business. Executive shall, at all times, both during employment by the Company and thereafter, keep all Proprietary Information in confidence and trust and shall not use or disclose any Proprietary Information without the written consent of the Company, except as necessary in the ordinary course of Executive’s duties. Executive shall keep the terms of this Agreement in confidence and trust and shall not disclose such terms, except to Executive’s family, accountants, financial advisors, or attorneys, or as otherwise authorized or required by law. The Parties acknowledge that pursuant to the Defend Trade Secrets Act of 2016 (the “DTSA”), an individual may not be held criminally or civilly liable under any Federal or state trade secret law for disclosure of a trade secret that (i) is made (A) in confidence to a Federal, state or local governmental authority, either directly or indirectly, or to an attorney; and (B) solely for the purpose of reporting or investigating a suspected violation of applicable law; or (ii) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. Under the DTSA, any employee, contractor, or consultant who is found to have wrongfully misappropriated trade secrets (as the terms “misappropriate” and “trade secret” are defined in the DTSA) may be liable for, among other things, exemplary damages and attorneys’ fees.

4.2Company Property. Executive recognizes that all Proprietary Information, however stored or memorialized, and all identification cards, keys, flash drives, computers, mobile phones, Personal Data Assistants, telephone numbers, access codes, marketing materials, documents, records and other equipment or property which the Company provides are the sole property of the Company. Upon termination of employment, Executive shall (1) refrain from taking any such property from the Company’s premises, and (2) return any such property in Executive’s possession within ten (10) business days.

4.3Assignment of Inventions to the Company. Executive shall promptly disclose to the Company all improvements, inventions, formulas, processes, computer programs, know­ how and trade secrets developed, whether or not patentable, made or conceived or reduced to practice or developed by Executive, either alone or jointly with others, during and related to Executive’s employment and the Company’s business or while using the Company’s equipment, supplies, facilities or trade secret information (collectively, “Inventions”). All Inventions and other intellectual property rights shall be the sole property of the Company and shall be “works made for hire.” Executive hereby assigns to the Company any rights Executive may have or acquire in all Inventions and agrees to perform, during and after employment with the Company, at the Company’s expense including reasonable compensation to Executive, all acts reasonably necessary by the Company in obtaining and enforcing intellectual property rights with respect to such Inventions. Executive hereby irrevocably appoints the Company and its officers and agents as Executive’s attorney-in-fact to act for and in Executive’s name and stead with respect to such Inventions.

Executive acknowledges and agrees that the restrictions are reasonable and do not, and will not, unduly impair his or her ability to make a living after the termination of his or her employment with the Company. The provisions of SECTION 4 and SECTION 5 shall survive the expiration or sooner termination of this Agreement. For purposes of SECTION 4 and SECTION 5, “Company” shall include any subsidiary, business unit or affiliate of the Company with respect to which Executive performs Executive’s duties.

6.12Section 409A. ThisAgreement is intended to be written, administered, interpreted and construed in a manner such that no payment or benefits provided under this Agreement become subject to (a) the gross income inclusion set forth within Code Section 409A(a)(l)(A) or (b) the interest and additional tax set forth within Code Section 409A(a)(l)(B) (together, referred to herein as the “Section 409A Penalties”), including, where appropriate, the construction of defined terms to have meanings that would not cause the imposition of Section 409A Penalties. In no event shall the Company be required to provide a tax gross-up payment to Executive or otherwise reimburse Executive with respect to Section 409A Penalties. In the event that following the date hereof the Company reasonably determines that any compensation or benefits payable under this Agreement may be subject to Section 409A of the Code, the Company and the Executive shall work together to adopt such amendments to this Agreement or adopt other policies or procedures (including amendments, policies and procedures with retroactive effect), or take any other commercially reasonable actions necessary or appropriate to (x) exempt the compensation and benefits payable under this Agreement from Section 409A of the Code and/or preserve the intended tax treatment of the compensation and benefits provided with respect to this Agreement or (y) comply with the requirements of Section 409A of the Code and related Department of Treasury guidance.

To this effect, they shall consult and negotiate with each other in good faith and, recognizing their mutual interests, attempt to reach a just and equitable solution satisfactory to both parties. If the parties do not reach such solution within a period of 60 days, then, upon written notice by either party to the other, all such disputes, claims, questions, or differences shall be finally settled by confidential binding arbitration administered by the American Arbitration Association in accordance with the provisions of its Employment Arbitration Rules, unless such claim is precluded by law from being settled through arbitration. Such arbitration shall take place in Raleigh, North Carolina. Any arbitrator selected by the parties to arbitrate any such dispute shall have practiced predominately in the field of employment law for no less than ten years. The arbitrator will have the power to interpret this Agreement. Any determination or decision by the arbitrator shall be binding upon the parties and may be enforced in any court of law. The parties agree that this arbitration provision does not apply to the right of Executive to file a charge, testify, assist or participate in any manner in an investigation, hearing or proceeding before the Equal Employment Opportunity Commission or any other agency pertaining to any matters covered by this Agreement and within the jurisdiction of the agency. Both Parties agree that this arbitration clause has been bargained for by the Parties upon advice of their respective counsel.

14

6.15. Code Section 280G. Notwithstanding any other provision of this Agreement, if it is determined that the benefits or payments payable under this Agreement, taking into account other benefits or payments provided under other plans, agreements or arrangements, constitute Parachute Payments that would subject the Executive to tax under Section 4999 of the Code, it must be determined whether the Executive will receive the total payments due or the Reduced Amount. The Executive will receive the Reduced Amount if the Reduced Amount results in equal or greater Net After Tax Receipts than the Net After Tax Receipts that would result from the Executive receiving the total payments due.

If it is determined that the total payments should be reduced to the Reduced Amount, the Company must promptly notify the Executive of that determination, including a copy of the detailed calculations by an accounting firm or other professional organization qualified to make the calculation that was selected by the Company and acceptable to the Executive (the “Accounting Firm”). The Company shall pay the fees and expenses of the Accounting Firm. All determinations made by the Accounting Firm under this SECTION 6.15 are binding upon the Company and the Executive, subject to any differing determination by the Internal Revenue Service.

It is the intention of the Company and the Executive to reduce the payments under this Agreement and any other plan, agreement or arrangement only if the aggregate Net After Tax Receipts to the Executive would thereby be increased.

If it is determined that the total payments should be reduced to the Reduced Amount, any reduction shall be in the order that would provide the Executive with the largest amount of Net After Tax Receipts (subject to the remainder of this sentence, pro rata if two alternatives provide the same result) and shall, to the extent permitted by Code Section 280G and 409A be designated by the Executive. The Executive shall at any time have the unilateral right to forfeit any equity grant in whole or in part.

For purposes of this Agreement, the term “Net After Tax Receipt” means the Present Value of the total payments or the Reduced Amount, as applicable, net of all federal, state and local income and payroll taxes imposed on the Executive, including Section 4999 of the Code, determined by applying the highest marginal rate of income taxes which applied to the Executive’s taxable income for the immediately preceding taxable year. For purposes of this Agreement, the term “Parachute Payment” means a payment (under this Agreement or any other plan, agreement or arrangement) that is described in Section 280G(b)(2) of the Code, determined in accordance with Section 280G of the Code and the regulations thereunder. For purposes of this Agreement, the term “Present Value” means the value determined in accordance with Section 280G(d)(4) of the Code and the regulations thereunder. For purposes of this Agreement, the term “Reduced Amount” means the largest amount of Parachute Payments that is less than the total Parachute Payments and that may be paid to the Executive without subjecting the Executive to tax under Section 4999 of the Code.

3.4Severance Benefits.

(a)Termination without Cause or for Good Reason. Subject to the terms andconditions of eligibility for Executive’s receipt of severance benefits under this Agreement, including the timely execution and delivery (and non-revocation) by Executive of the Separation Agreement and General Release as set forth in SECTION 6.10, the Company shall pay to Executive, as severance benefits, which amounts are in addition to the Compensation upon Termination set forth in SECTION 3.3 herein:

(i)An amount equal to his current annualized Base Salary which shall be paid to Executive on a salary continuation basis according to the Company’s normal payroll practices over the 12 month period following the date the Executive incurs a Separation from Service, but in no event less frequently than monthly.

(ii)An amount equal to the Executive's Target Bonus referenced in SECTION 2.1(b) (based upon his Base Salary as of the date of termination) which shall be paid to Executive when the Annual Cash Bonus for such year is paid to other executives of the Company.

(iii)Subject to (1) the Executive’s timely election of continuation coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), and (2) the Executive’s continued copayment of premiums at the same level and cost to the Executive as if the Executive were an employee of the Company (excluding, for purposes of calculating cost, an employee’s ability to pay premiums with pre-tax dollars), continued participation in the Company’s group health plan (to the extent permitted under applicable law and the terms of such plan) which covers the Executive (and the Executive’s eligible dependents) for a period of twelve (12) months at the Company’s expense, provided that the Executive is eligible and remains eligible for COBRA coverage. The Company may modify its obligation under this SECTION 3.4(a)(ii) to the extent reasonably necessary to avoid any penalty or excise taxes imposed on it in connection with the continued payment of premiums by the Company under the Patient Protection and Affordable Care Act of 2010, as amended.

(iv)The Company shall accelerate the vesting of the Executive’s then-outstanding and unvested stock options, stock appreciation rights, restricted stock units or shares, or any other Company time-based equity compensation awards, to the extent that such awards would have vested solely upon the Executive’s continued employment within twelve months following the date of termination.

(v)In addition to the benefits described in SECTION 3.4(a)(i), (ii) and (iii), in the event that there is a Change in Control of the Company and (1) the successor fails to assume and continue this Agreement, or (2) within ninety (90) days preceding or within six (6) months after the Change in Control (a) the Executive is terminated without Cause, or (b) Executive terminates for Good Reason, the Company shall (I) accelerate the vesting of (x) the Executive’s then-outstanding and unvested stock options, stock appreciation rights, restricted stock units or shares, or any other Company time-based equity compensation awards, to the extent that such awards would have vested solely upon the Executive’s continued employment, such that one hundred percent (100%) of such awards

6

become vested in full and (y) the target level of the Executive’s then-outstanding performance stock units or other Company equity compensation awards that vest based on achievement of specified performance criteria, such that such awards become fully vested at the target level of award, (II) continue Executive’s Base Salary, as provided under SECTION 3.4(i) for 24 months rather than 12 months, and (III)  pay Executive an amount equal to the Executive’s Target Bonus (under SECTION 2.1 (b), based upon his Base Salary as of the date of termination), which amount shall be paid to Executive when the Company pays the Annual Cash Bonus for the calendar year that commences immediately after Executive’s termination (and for clarity, shall be in addition to the Target Bonus paid to Executive under SECTION 3.4(ii) – such that Executive receives two Target Bonuses).

(b)Termination for Executive’s Death or Disability. In the event of Executive’s death or Disability, the Company shall accelerate the vesting of the Executive’s then-outstanding and unvested stock options, stock appreciation rights, restricted stock units or shares, or any other Company time-based equity compensation awards, to the extent that such awards would have vested solely upon the Executive’s continued employment within twelve months following the date of termination.

(c)Notwithstanding any other provision of this Agreement, any severance benefits that would otherwise have been paid before the Company’s first normal payroll payment date falling on or after the sixtieth (60th) day after the date on which the Executive incurs a Separation from Service (the “First Payment Date”) shall be made on the First Payment Date. Each separate severance installment payment and each other payment that Executive may be eligible to receive under this Agreement shall be a separate payment under this Agreement for all purposes.

(d)Notwithstanding anything to the contrary in this Agreement, with respect to any severance benefits or amounts payable to the Executive under this Agreement, in no event shall a termination of employment occur under this Agreement unless such termination constitutes a Separation from Service. For purposes of this Agreement, a “Separation from Service” shall mean the Executive’s “separation from service” with the Company as such term is defined in Treasury Regulation Section 1.409A-1(h) and any successor provision thereto.

Notwithstanding anything to the contrary in this Agreement, to the maximum extent permitted by applicable law, amounts payable to the Executive pursuant to this SECTION 3.4 shall be made in reliance upon Treas. Reg. Section 1.409A-1(b)(9) (Separation Pay Plans) or Treas. Reg. Section 1.409A-l(b)(4) (Short-Term Deferrals). However, to the extent any such payments are treated as non-qualified deferred compensation subject to Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), then if Executive is deemed at the time of his Separation from Service to be a “specified employee” for purposes of Section 409A(a)(2)(B)(i) of the Code, then to the extent delayed commencement of any portion of the benefits to which the Executive is entitled under this Agreement is required in order to avoid a prohibited distribution under Section 409A(a)(2)(B)(i) of the Code, such portion of the Executive’s termination benefits shall not be provided to the Executive prior to the earlier of (i) the expiration of the six-month period measured from the date of the Executive’s Separation from Service or (ii) the date of Executive’s death. Upon the earlier of such dates, all payments deferred pursuant to this SECTION 3.4(d) shall be paid in a lump sum to the Executive. Thereafter, payments will resume in accordance with this Agreement.

7

The determination of whether the Executive is a “specified employee” for purposes of Section 409A(a)(2)(B)(i) of the Code as of the time of his Separation from Service shall be made by the Company in accordance with the terms of Section 409A of the Code and applicable guidance thereunder (including without limitation Treas. Reg. Section 1.409A-l(i) and any successor provision thereto).

(e)The Executive shall have no duty or obligation to mitigate the amounts due under SECTION 3.4(a) above and any amounts earned by Executive from other employment shall not be offset or reduce the amounts due hereunder.

(f)The term “Change in Control” shall mean the occurrence of any of the following events: (i) the Board approves a plan of liquidation, dissolution or winding-up of the Company, (ii) the consummation of a sale or other disposition of all or substantially all of the assets of the Company and its subsidiaries, (iii) any “person,” as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (other than the Company, any trustee or other fiduciary holding securities under any employee benefit plan of the Company, or any company owned, directly or indirectly, by the stockholders of the Company in substantially the same proportions as their ownership of Common Stock of the Company), becoming the beneficial owner (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing more than 50% of the combined voting power of the Company’s then outstanding securities or otherwise acquiring the power to elect or designate a majority of the members of the Board, (iv) a merger or consolidation of the Company with any other corporation or entity (a “Merger Partner”), as a result of which (A) the voting securities of the Merger Partner outstanding immediately prior thereto represent (either by remaining outstanding or by being converted into voting securities of a surviving entity) more than 50% of the combined voting power of the voting securities of the Company or such surviving entity outstanding immediately after such merger or consolidation, or (B) the shareholders of the Merger Partner immediately prior thereto have the power to elect or designate a majority of the members of the Board of the Company or such surviving entity; provided, however, that a merger or consolidation effected to implement a recapitalization of the Company (or similar transaction) in which no person (other than those covered by the exceptions in clause (iii) above) acquires more than 50% of the combined voting power of the Company’s then outstanding securities or the power to elect or designate a majority of the members of the Board shall not constitute a Change in Control of the Company.

In the event that following the date hereof the Company reasonably determines that any compensation or benefits payable under this Agreement may be subject to Section 409A of the Code, the Company and the Executive shall work together to adopt such amendments to this Agreement or adopt other policies or procedures (including amendments, policies and procedures with retroactive effect), or take any other commercially reasonable actions necessary or appropriate to (x) exempt the compensation and benefits payable under this Agreement from Section 409A of the Code and/or preserve the intended tax treatment of the compensation and benefits provided with respect to this Agreement or (y) comply with the requirements of Section 409A of the Code and related Department of Treasury guidance.

6.13Indemnification, etc. The Company shall indemnify and hold harmless Executive to the fullest extent permitted by law for any action or inaction he takes in good faith with regard to the Company or parent or any benefit plan of either, in accordance with the Company’s Articles of Incorporation and By-laws. Further, the Company shall cover Executive on its directors’ and officers’ liability insurance policies to no less extent than that which covers any other officer or director of the Company.

6.14Arbitration. Except with respect to the Company’s enforcement of the covenants in SECTION 4 and SECTION 5, in the event that either Executive or the Company (or their successor and assigns, or any other person claiming benefits on behalf of or through them) has a dispute, claim, question, or disagreement arising from or relating to this Agreement or the breach thereof, the parties hereto shall use their best efforts to settle the dispute, claim, question, or disagreement. To this effect, they shall consult and negotiate with each other in good faith and, recognizing their mutual interests, attempt to reach a just and equitable solution satisfactory to both parties. If the parties do not reach such solution within a period of 60 days, then, upon written notice by either party to the other, all such disputes, claims, questions, or differences shall be finally settled by confidential binding arbitration administered by the American Arbitration Association in accordance with the provisions of its Employment Arbitration Rules, unless such claim is precluded by law from being settled through arbitration. Such arbitration shall take place in Atlanta, Georgia. Any arbitrator selected by the parties to arbitrate any such dispute shall have practiced predominately in the field of employment law for no less than ten years. The arbitrator will have the power to interpret this Agreement. Any determination or decision by the arbitrator shall be binding upon the parties and may be enforced in any court of law. The parties agree that this arbitration provision does not apply to the right of Executive to file a charge, testify, assist or participate in any manner in an investigation, hearing or proceeding before the Equal Employment Opportunity Commission or any other agency pertaining to any matters covered by this Agreement and within the jurisdiction of the agency. Both Parties agree that this arbitration clause has been bargained for by the Parties upon advice of their respective counsel.

6.15. Code Section 280G. Notwithstanding any other provision of this Agreement, if it is determined that the benefits or payments payable under this Agreement, taking into account other benefits or payments provided under other plans, agreements or arrangements, constitute Parachute Payments that would subject the Executive to tax under Section 4999 of the Code, it must be

14

determined whether the Executive will receive the total payments due or the Reduced Amount. The Executive will receive the Reduced Amount if the Reduced Amount results in equal or greater Net After Tax Receipts than the Net After Tax Receipts that would result from the Executive receiving the total payments due.

If it is determined that the total payments should be reduced to the Reduced Amount, the Company must promptly notify the Executive of that determination, including a copy of the detailed calculations by an accounting firm or other professional organization qualified to make the calculation that was selected by the Company and acceptable to the Executive (the “Accounting Firm”). The Company shall pay the fees and expenses of the Accounting Firm. All determinations made by the Accounting Firm under this SECTION 6.15 are binding upon the Company and the Executive, subject to any differing determination by the Internal Revenue Service.

It is the intention of the Company and the Executive to reduce the payments under this Agreement and any other plan, agreement or arrangement only if the aggregate Net After Tax Receipts to the Executive would thereby be increased.

If it is determined that the total payments should be reduced to the Reduced Amount, any reduction shall be in the order that would provide the Executive with the largest amount of Net After Tax Receipts (subject to the remainder of this sentence, pro rata if two alternatives provide the same result) and shall, to the extent permitted by Code Section 280G and 409A be designated by the Executive. The Executive shall at any time have the unilateral right to forfeit any equity grant in whole or in part.

For purposes of this Agreement, the term “Net After Tax Receipt” means the Present Value of the total payments or the Reduced Amount, as applicable, net of all federal, state and local income and payroll taxes imposed on the Executive, including Section 4999 of the Code, determined by applying the highest marginal rate of income taxes which applied to the Executive’s taxable income for the immediately preceding taxable year. For purposes of this Agreement, the term “Parachute Payment” means a payment (under this Agreement or any other plan, agreement or arrangement) that is described in Section 280G(b)(2) of the Code, determined in accordance with Section 280G of the Code and the regulations thereunder. For purposes of this Agreement, the term “Present Value” means the value determined in accordance with Section 280G(d)(4) of the Code and the regulations thereunder. For purposes of this Agreement, the term “Reduced Amount” means the largest amount of Parachute Payments that is less than the total Parachute Payments and that may be paid to the Executive without subjecting the Executive to tax under Section 4999 of the Code.

1

(b)This general release of Claims by Executive includes, without limitation, (i) all Claims based upon actions or omissions (or alleged actions or omissions) that have occurred up to and including the date of this Agreement, regardless of ripeness or other limitation on immediate pursuit of any Claim in the absence of this Agreement; (ii) all Claims relating to or arising out of Executive’s employment with and separation from the Company; (iii) all Claims (including Claims for discrimination, harassment, and retaliation) arising under any federal, state or local statute, regulation, ordinance, or the common law, including without limitation, Claims arising under Title VII of the Civil Rights Act of 1964, the Americans With Disabilities Act, the Age Discrimination in Employment Act, as amended, the Family and Medical Leave Act and the Employee Retirement Income Security Act of 1974, the Civil Rights Act of 1991, the Equal Pay Act, the Fair labor Standards Act, 42 U.S.C. § 1981, and any other federal or state law, local ordinance or common law including for wrongful discharge, breach of implied or express contract, intentional or negligent infliction of emotional distress, defamation or other tort; and (iv) all Claims for reinstatement, attorney’s fees, interest, costs, wages or other compensation.

(c)Executive agrees that there is a risk that each and every injury which he or she may have suffered by reason of his or her employment relationship might not now be known, and there is a further risk that such injuries, whether known or unknown at the date of this Agreement, might become progressively worse, and that as a result thereof further damages may be sustained by Executive; nevertheless, Executive desires to forever and fully release and discharge the Company Parties, and he or she fully understands that by the execution of this Agreement no further claims for any such injuries may ever be asserted.

(d)This general release does not release any Claim that relates to: (i) Executive’s right to enforce this Agreement; (ii) any rights Executive may have to indemnification from personal liability or to protection under any insurance policy maintained by the Company, including without limitation any general liability, EPLI, or directors and officers insurance policy or any contractual indemnification agreement; (iii) Executive’s right, if any, to government­ provided unemployment and worker’s compensation benefits; or (iv) Executive’s rights under any Company Executive benefit plans (i.e. health, disability or retirement plans), which by their explicit terms survive the termination of Executive’s employment.

(e)Executive agrees that the consideration set forth in SECTION 3 above shall constitute the entire consideration provided under this Agreement, and that Executive will not seek from the Company Parties any further compensation or other consideration for any claimed obligation, entitlement, damage, cost or attorneys’ fees in connection with the matters encompassed by this Agreement.

(f)Executive understands and agrees that if any facts with respect to this Agreement or Executive’s prior treatment by or employment with the Company are found to be different from the facts now believed to be true, Executive expressly accepts, assumes the risk of, and agrees that this Agreement shall remain effective notwithstanding such differences. Executive agrees that the various items of consideration set forth in this Agreement fully compensate for

2

said risks, and that Executive will have no legal recourse against the Company in the event of discovery of a difference in facts.

(g)Executive agrees to the release of all known and unknown claims, including expressly the waiver of any rights or claims arising out of the Federal Age Discrimination in Employment Act, 29 U.S.C. § 621, et seq. (“ADEA’’), and in connection with such waiver of ADEA claims, and as provided by the Older Worker Benefit Protection Act, Executive understands and agrees as follows:

(i) Executive has the right to consult with an attorney before signing this Agreement, and is hereby advised to do so;

(ii) Executive shall have a period of forty-five (45) days from the Termination Date (or from the date of receipt of this Agreement if received after the Termination Date) in which to consider the terms of the Agreement (the “Review Period”). Executive may at his or her option execute this Agreement at any time during the Review Period. If the Executive does not return the signed Agreement to the Company prior to the expiration of the 45 day period, then the offer of severance benefits set forth in this Agreement shall lapse and shall be withdrawn by the Company;

(iii) Executive may revoke this Agreement at any time during the first seven (7) days following Executive’s execution of this Agreement, and this Agreement and release shall not be effective or enforceable with respect to any Claim under the ADEA until the seven-day period has expired (“Revocation Period Expiration Date”). Notice of a revocation by the Executive must be made to the designated representative of the Company (as described below) within the seven (7) day period after Executive signs this Agreement. If Executive revokes this Agreement, it shall not be effective or enforceable against the Company Parties. Accordingly, the “Effective Date” of this Agreement shall be on the eighth (8th) day after Executive signs the Agreement and returns it to the Company, and provided that Executive does not revoke the Agreement during the seven (7) day revocation period;

In the event Executive elects to revoke this release pursuant to SECTION 4(g)(iii) above, Executive shall notify Company by hand-delivery, express courier or certified mail, return receipt requested, within seven (7) days after signing this Agreement to: ATTN: Chief Executive Officer, BMC Stock Holdings, Inc., Two Lake Side Commons, Suite 500, 980 Hammond Drive, Atlanta, Georgia 30328. In the event that Executive exercises his or her right to revoke this release pursuant to SECTION 4(g)(iii) above, any and all obligations of Company under this Agreement shall be null and void. Executive agrees that by signing this Agreement prior to the expiration of the forty-five (45) day period he or she has voluntarily waived his or her right to consider this Agreement for the full forty-five (45) day period.

3

EXECUTIVE AGREES THAT THE CONSIDERATION RECEIVED BY HIM OR HER UNDER THIS AGREEMENT, INCLUDING THE PAYMENTS DESCRIBED ABOVE, IS IN FULL AND COMPLETE SATISFACTION OF ANY CLAIMS THAT EXECUTIVE MAY HAVE, OR MAY HAVE HAD, ARISING OUT OF EXECUTIVE’S EMPLOYMENT WITH THE COMPANY (INCLUDING FOR THE AVOIDANCE OF DOUBT, ALL OF ITS SUBSIDIARIES OR AFFILIATES) OR THE TERMINATION OF THAT EMPLOYMENT, UP TO THE DATE OF EXECUTION OF THIS AGREEMENT. EXECUTIVE ACKNOWLEDGES THAT HE OR SHE UNDERSTANDS THAT, BY ENTERING INTO THIS AGREEMENT, HE OR SHE NO LONGER HAS THE RIGHT TO ASSERT ANY CLAIM OR LAWSUIT OF ANY KIND ATTEMPTING TO RECOVER MONEY OR ANY OTHER RELIEF AGAINST THE COMPANY PARTIES FOR ACTS OR INJURIES ARISING OUT OF EXECUTIVE’S FORMER EMPLOYMENT BY COMPANY (INCLUDING FOR THE AVOIDANCE OF DOUBT, ALL OF ITS SUBSIDIARIES OR AFFILIATES) OR THE TERMINATION OF THAT EMPLOYMENT.

Such claims further include any claims Executive may have pursuant to an internal grievance procedure at Company (including for the avoidance of doubt, all of its subsidiaries or affiliates). Executive does not waive any rights or claims that may arise after the date this Agreement is executed.

5.Review of Agreement; No Assignment of Claims.

6.No Claims. Each party represents that it has not filed any Claim against the other Party with any state, federal or local agency or court and that it will not file any Claim at any time regarding the matters covered by this Agreement; provided, however, that nothing in this Agreement shall be construed to prohibit Executive from filing a Claim, including a challenge to the validity of this Agreement, with the Equal Employment Opportunity Commission or participating in any investigation or proceeding conducted by the Equal Employment Opportunity Commission; provided, further, that Executive acknowledges that he will not be entitled to recover any monetary or other damages in connection with or as a result of any such EEOC or federal employment practices agency proceeding.

Executive agrees that disclosure by Executive in violation of this Agreement would cause so much injury to the Company that money alone could not fully compensate the Company and that the Company is entitled to injunctive and equitable relief. Executive also agrees that the Company would be entitled to recover money from Executive if this Agreement were violated.

10.Ongoing Covenants. Executive acknowledges that nothing in this Agreement shall limit or otherwise impact Executive’s continuing obligations of confidentiality to the Company in accordance with Company policy and applicable law, or any applicable Company policies or agreements between the Company and Executive with respect to non-competition or non-solicitation, and Executive covenants and agrees to abide by all such continuing obligations.

Nothing herein prohibits Executive from communicating, without notice to or approval by the Company, with any federal government agency about a potential violation of a federal law or regulation.

12.    Integration; Severability. The terms and conditions of this Agreement constitute the entire agreement between Company and Executive and supersede all previous communications, either oral or written, between the parties with respect to the subject matter of this Agreement. No agreement or understanding varying or extending the terms of this Agreement shall be binding upon either party unless in writing signed by or on behalf of such party. In the event that a court finds any portion of this Agreement unenforceable for any reason whatsoever, Company and Executive agree that the other provisions of the Agreement shall be deemed to be severable and will continue in full force and effect to the fullest extent permitted by law.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Basis of presentation

The accompanying consolidated financial statements have been prepared by management in conformity with U.S generally accepted accounting principles (“U.S. GAAP”).

Principles of consolidation

The consolidated financial statements include all accounts of BMC and its wholly-owned subsidiaries. All material intercompany accounts and transactions have been eliminated in consolidation.

Use of estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company evaluates these estimates and judgments on an ongoing basis and bases its estimates on historical experience, current conditions and various other assumptions that are believed to be reasonable under the circumstances. The results of these estimates form the basis for making judgments about the carrying values of assets and liabilities as well as identifying and assessing the accounting treatment with respect to commitments and contingencies. The significant estimates which could change by a material amount in the near term include revenue recognition for construction services, accounts receivable reserves, estimated losses on uncompleted contracts and changes in contract estimates, inventory reserves, supplier rebates, goodwill impairment, impairment of property and equipment, insurance reserves, warranties and share-based compensation. Actual results may differ materially from these estimates under different assumptions or conditions.

Business and credit concentrations

The Company maintains cash at financial institutions in excess of federally insured limits. Accounts receivable potentially expose the Company to concentrations of credit risk. Mitigating this credit risk is collateral underlying certain accounts receivable (perfected liens or lien rights) as well as the Company’s analysis of a customer’s credit history prior to extending credit. Concentrations of credit risk with respect to accounts receivable are limited due to the Company’s large number of customers and their dispersion across various regions of the United States. At December 31, 2018 and 2017, no customer represented more than 10% of accounts receivable. For the years ended December 31, 2018, 2017 and 2016, no customer accounted for more than 10% of revenue.

The Company’s future results could be adversely affected by a number of factors including competitive pressure on sales and pricing, weather conditions, consumer spending and debt levels, interest rates, existing residential home sales and new home construction, lumber prices and product mix.

Cash and cash equivalents

Cash equivalents are highly liquid investments that are readily convertible to known amounts of cash and have a maturity of three months or less from the time of purchase. As of December 31, 2018 and 2017, the Company had cash equivalents of $146.1 million and $0, respectively. Cash equivalents are valued at amortized cost, which approximates fair value due to the short-term maturity of these instruments, and was classified as a Level 1 or Level 2 measurement in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 820, Fair Value Measurements and Disclosures (“ASC 820”).

Book overdrafts occur when purchases on corporate purchasing cards and checks written exceed available bank balances at a specific bank, despite there being cash at the Company’s other financial institutions. For accounting purposes, the Company reclassifies these book overdrafts to accounts payable on the consolidated balance sheets. Book overdrafts included in accounts payable were $0.1 million at December 31, 2018 and 2017.

Fair value of financial instruments

ASC 820 clarifies the definition of fair value, prescribes methods for measuring fair value, and establishes a fair value hierarchy to classify the inputs used in measuring fair value as follows:

Level 1	Inputs are unadjusted quoted prices in active markets for identical assets or liabilities available at the measurement date.
Level 2	Inputs are unadjusted quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, inputs other than quoted prices that are observable, and inputs derived from or corroborated by observable market data.
Level 3	Inputs are unobservable inputs which reflect the reporting entity’s own assumptions on what assumptions the market participants would use in pricing the asset or liability based on the best available information.

If a financial instrument uses inputs that fall in different levels of the hierarchy, the instrument is categorized based upon the lowest level of input that is significant to the fair value calculation.

Accounts receivable

Accounts receivable result from the extending of credit to trade customers for the purchase of goods and services. The terms generally provide for payment within 30 days of being invoiced. On occasion, when necessary to compete in certain circumstances, the Company will sell product under extended payment terms. Accounts receivable are stated at estimated net realizable value. The allowance for doubtful accounts is based on an assessment of individual past due accounts, historical write-off experience, accounts receivable aging, customer disputes and the business environment. Account balances are charged off when the potential for recovery is considered remote. The Company grants trade discounts on a percentage basis. The Company records an allowance against accounts receivable for the amount of discounts it estimates will be taken by customers. The discounts are recorded as a reduction to revenue when products are sold.

Consideration received from suppliers

The Company enters into agreements with many of its suppliers providing for inventory purchase rebates (“supplier rebates”) upon achievement of specified volume purchasing levels. Supplier rebates are accrued as part of cost of goods sold based on progress towards earning the supplier rebates, taking into consideration cumulative purchases of inventory to date and projected purchases through the end of the year. The Company estimates the rebates applicable to inventory on-hand at each period end based on the estimated percentage of supplier rebates to be earned. The Company also receives consideration from suppliers to promote their products (“marketing and advertising allowances”), which are accrued as part of cost of goods sold or selling, general and administrative expenses, depending on the nature of the allowance. Total rebates and marketing and advertising allowances receivable at December 31, 2018 and 2017 were $18.0 million and $23.3 million, respectively, included in prepaid expenses and other current assets.

Revenue recognition

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in Accounting Standards Update 2014-09, Revenue from Contracts with Customers, as amended (“Topic 606”). The Company’s building products contracts typically contain a promise to supply multiple distinct products and thus, they generally contain multiple performance obligations under Topic 606. Depending on the nature of the promises within the Company’s construction services contracts and whether they are distinct under Topic 606, there may be a single performance obligation or multiple performance obligations. For contracts with multiple performance obligations, the contract’s transaction price is allocated to each distinct performance obligation based on the standalone selling price of each distinct good or service, which is generally determined based on the prices charged to customers.

The Company recognizes revenue for its building products contracts when control of the promised goods (the performance obligations) is transferred to the Company’s customers. This generally occurs at a point in time when the products are delivered and the customer obtains physical possession, legal title and the risks and rewards of ownership. However, for certain product offerings, products are customized to customer specifications and the customer benefits from the Company’s performance over time as deliveries are made. As such, the Company has determined that an output method based on units delivered best depicts the transfer of control to the customer.

The Company generally recognizes revenue for its construction services contracts over time using cost based input methods. Periodic estimates of progress towards completion are made based on either a comparison of labor costs incurred to date with total estimated contract labor costs or total costs incurred to date with total estimated contract costs. Incurred costs represent work performed, which correspond and best depict transfer of control to the customer.

Contract revenues and contract costs to be recognized are dependent on the accuracy of estimates, including quantities of materials, labor productivity and other cost estimates. Historically, the Company has made reasonable estimates of the extent of progress towards completion and contract completion costs. Due to uncertainties inherent in the estimation process, it is possible that actual completion costs may vary from estimates. Revenue recognized for performance obligations satisfied over time for the year ended December 31, 2018 represented approximately 26% of total revenues.

Estimated losses on uncompleted contracts and changes in contract estimates reflect the Company’s best estimate of probable losses of unbilled receivables, and are recognized in the period such revisions are known and can be reasonably estimated. These estimates are recognized in cost of sales. Estimated losses on uncompleted contracts and changes in contract estimates are established by assessing estimated costs to complete, change orders and claims for uncompleted contracts. Assumptions for estimated costs to complete include material prices, labor costs, labor productivity and contract claims. Such estimates are inherently uncertain and it is possible that actual completion costs may vary from these estimates.

All sales recognized are net of allowances for discounts and estimated returns, based on historical experience. Taxes assessed by governmental authorities that are directly imposed on the Company’s revenue-producing transactions are excluded from sales. The Company accounts for shipping and handling costs associated with its contracts as a fulfillment cost and expenses these as incurred within selling, general and administrative expenses.

Contract balances

The timing of revenue recognition, invoicing and cash collection affects receivables, contract assets and contract liabilities on the Company’s consolidated balance sheets. For building products contracts that contain performance obligations satisfied at a point in time, the Company recognizes revenue upon satisfaction of the performance obligation and then bills the customer, resulting in a receivable. For building products contracts that contain performance obligations satisfied over time, the Company recognizes revenue as the performance obligation is satisfied, but prior to billing, resulting in an unbilled receivable, as the Company has an unconditional right to payment.

For the Company’s construction services contracts, amounts are generally billed as work progresses in accordance with agreed-upon contractual terms. Revenue is also recognized over time as the performance obligations are satisfied, which can result in contract assets and liabilities, on a contract-by-contract basis, due to timing differences between billing and revenue recognition. Contract assets include unbilled amounts when the revenue recognized exceeds the amount billed to the customer. Conversely, contract liabilities include amounts that have been billed to the customer in excess of the revenue recognized.

At times, the Company will have a right to payment from previous performance that is conditional on something other than passage of time, such as retainage, which creates a contract asset. Conversely, the Company may receive advances from customers prior to the Company’s performance, which creates a contract liability.

Contract assets are reclassified to a receivable when the right to consideration becomes unconditional. The Company’s terms generally provide for payment within 30 days of being invoiced. On occasion, when necessary to compete in certain circumstances, the Company will offer extended payment terms, which do not exceed one year.

Shipping and handling costs

The Company includes shipping and handling costs in selling, general and administrative expenses and depreciation expense on the consolidated statements of operations. Shipping and handling costs included in selling, general and administrative expenses were $189.6 million, $172.2 million and $152.7 million for the years ended December 31, 2018, 2017 and 2016, respectively. Shipping and handling costs included in depreciation expense were $22.9 million, $24.8 million and $20.9 million for the years ended December 31, 2018, 2017 and 2016, respectively.

Property and equipment

Property and equipment are stated at cost. Expenditures for renewals and betterments, which extend the useful lives of assets, are capitalized while maintenance and repairs are charged to expense as incurred. Property and equipment obtained through acquisition are stated at estimated fair market value as of the acquisition date, and are depreciated over their estimated remaining useful lives, which may differ from the Company’s stated policies for certain assets. Gains and losses related to the sale of property and equipment are recorded as selling, general and administrative expenses.

Property and equipment are depreciated using the straight-line method and are generally depreciated over the following estimated service lives:

Buildings and improvements	3–30 years
Leasehold improvements	Lesser of life of the asset or remaining
	lease term, and not to exceed 15 years
Furniture, fixtures and equipment	2–10 years
Vehicles	4–10 years

Property and equipment that is expected to be sold within the next twelve months, is actively marketed in its current condition for a price that is reasonable in comparison to its estimated fair value and meets other relevant held-for-sale criteria are classified as assets held for sale. Assets held for sale are measured at the lower of carrying amount or fair value less costs to sell and are no longer depreciated. An impairment for assets held for sale is recognized if the carrying amount is not recoverable. Assets held for sale were not presented separately and were classified as other long-term assets in the consolidated balance sheets and were $1.3 million and $2.3 million at December 31, 2018 and 2017, respectively.

Goodwill and other intangible assets

At least annually, or more frequently as changes in circumstances indicate, the Company tests goodwill for impairment. To the extent that the carrying value of the net assets of any of the reporting units having goodwill is greater than their estimated fair value, the Company may be required to record impairment charges. The Company’s five operating segments, which have been determined to be the Company’s reporting units, are the Mid-Atlantic, Southeast, Texas, Intermountain and Western divisions. The chief operating decision maker (“CODM”) reviews aggregate information to allocate resources and assess performance. Based on the CODM’s review, as well as the similar economic characteristics, nature of products, distribution methods and customers of the divisions, the Company has aggregated its operating segments into one reportable segment. The Company is required to make certain assumptions and estimates regarding the fair value of the reporting units containing goodwill when assessing for impairment. Changes in the fact patterns underlying such assumptions and estimates could ultimately result in the recognition of additional impairment losses.

The Company completes its annual impairment assessment during the third quarter of each year. The Company did not recognize any impairment for the years ended December 31, 2018, 2017 and 2016. The Company may consider qualitative factors as part of its annual impairment assessment to determine whether it is more likely than not that a reporting unit’s carrying value exceeds its fair value. If the Company’s qualitative assessment indicates that goodwill impairment is more likely than not, the Company performs the two-step impairment test. Alternatively, the Company may bypass the qualitative test and initiate goodwill impairment testing with the first step of the two-step goodwill impairment test. During the first step of the goodwill impairment test, the fair value of the reporting unit is compared to its carrying value, including goodwill. The Company may derive a reporting unit’s fair value through a combination of the market approach (a guideline transaction method) and the income approach. The income approach uses a reporting unit’s projection of estimated future cash flows that is discounted at a market derived weighted average cost of capital. The projection uses management’s best estimates of economic and market conditions over the projected period including growth rates in sales, costs, estimates of future expected changes in operating margins and cash expenditures.

If the fair value of a reporting unit exceeds its carrying value, then the Company concludes no goodwill impairment has occurred. If the carrying value of the reporting unit exceeds its fair value, the Company performs the second step of the goodwill impairment test to measure possible goodwill impairment loss. During the second step, the implied fair value of the reporting unit’s goodwill is compared to the carrying value of its goodwill. If the carrying value of the reporting unit’s goodwill exceeds the implied fair value of the goodwill, the Company would recognize an impairment loss in an amount equal to the excess, not to exceed the carrying value of the reporting unit’s goodwill.

Acquired intangible assets other than goodwill are amortized over their weighted average amortization period unless they are determined to be indefinite. Acquired intangible assets are carried at cost, less accumulated amortization. For intangible assets purchased in a business combination, the estimated fair values of the assets received are used to establish the carrying value. The fair value of acquired intangible assets is determined using common valuation techniques, and the Company employs assumptions developed using the perspective of a market participant.

Impairment of long-lived assets

Long-lived assets, such as property, equipment and purchased intangible assets subject to amortization, are reviewed for impairment whenever facts and circumstances indicate that the carrying amount of an asset may not be recoverable. For impairment testing of long-lived assets, the Company identifies asset groups at the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the assets. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the estimated fair value of the asset.

Treasury stock

During the year ended December 31, 2018, the Company’s board of directors authorized a $75.0 million share repurchase program. Repurchases may be made at management’s discretion from time to time on the open market, subject to applicable laws, or through privately negotiated transactions. The repurchase program will expire on November 20, 2019 or may be suspended or discontinued at any time. During the year ended December 31, 2018, utilizing cash from operations, the Company repurchased 0.2 million shares at a weighted average price of $15.91 per share for a total cost of $2.9 million. These repurchased shares are available for future issuance and are reflected as treasury stock, at cost, on the consolidated balance sheet as of December 31, 2018. As of December 31, 2018, the Company had approximately $72.1 million of capacity remaining under the current share repurchase authorization. Subsequent to December 31, 2018, the Company repurchased 0.7 million shares at a weighted average price of $16.82 per share for a total cost of $11.5 million.

Employees have the option to surrender shares to the Company to satisfy their tax withholding obligations in connection with the vesting of restricted stock and restricted stock unit awards. These surrendered shares are reflected as treasury stock, at cost, on the consolidated balance sheet as of December 31, 2018 and 2017.

Merger and integration costs

Merger and integration costs related to the ongoing integration of Building Materials Holding Corporation (“BMHC”) and Stock Building Supply Holdings, Inc. (“SBS”), as a result of the 2015 merger transaction, consist primarily of severance, rebranding, system integration costs and professional fees.

Income taxes

The Company accounts for income taxes in accordance with ASC 740, Income Taxes (“ASC 740”), which requires an asset and liability approach for measuring deferred taxes based on temporary differences between the financial statement and tax basis of assets and liabilities existing at each balance sheet date using enacted tax rates for years in which taxes are expected to be paid or recovered.

The Company evaluates its deferred tax assets on a quarterly basis to determine whether a valuation allowance is required. In accordance with ASC 740, the Company assesses whether a valuation allowance should be established based on its determination of whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets depends primarily on: (i) the Company’s ability to carry back net operating losses to tax years where it has previously paid income taxes based on applicable federal law; (ii) the timing of the reversal of deferred tax liabilities and (iii) the Company’s ability to generate future taxable income during the periods in which the related deferred tax assets are deductible. The assessment of a valuation allowance includes giving appropriate consideration to all positive and negative evidence related to the realization of the deferred tax asset. This assessment considers, among other things, the nature, frequency and severity of current and cumulative losses, forecasts of future profitability, the duration of statutory carryforward periods, the Company’s experience with operating loss and tax credit carryforwards not expiring unused and tax planning alternatives. Significant judgment is required in determining the future tax consequences of events that have been recognized in the Company’s consolidated financial statements and/or tax returns. Actual outcomes of these future tax consequences could differ materially from the outcomes that the Company currently anticipates.

ASC 740 defines the methodology for recognizing the benefits of uncertain tax return positions as well as guidance regarding the measurement of the resulting tax benefits. These provisions require an enterprise to recognize the financial statement effects of a tax position when it is more likely than not, which is defined as a likelihood of more than 50%, based on technical merits, that the position will be sustained upon examination. The evaluation of whether a tax position meets the more likely than not recognition threshold requires a substantial degree of judgment by management based on the individual facts and circumstances. Actual results could differ from estimates. The Company had no material uncertain tax positions as of December 31, 2018.

The Company’s policy is to recognize interest and penalties related to income tax liabilities and unrecognized tax benefits in income tax expense.

Casualty and health insurance

The Company carries insurance for general liability, auto liability and workers’ compensation exposures subject to deductibles or self-insured retentions it believes to be reasonable under the circumstances, and the Company self-insures for employee and eligible dependent health care claims, with insurance purchased from independent carriers to cover individual claims in excess of the self-insured limits. The expected liability for unpaid claims, including incurred but not reported losses, is reflected on the consolidated balance sheets as a liability with current and long-term components. The amount recoverable from insurance providers is reflected on the consolidated balance sheets in prepaid expenses and other current assets. Provisions for losses are developed from actuarial valuations that rely upon the Company’s past claims experience, which considers both the frequency and settlement of claims. The casualty and health insurance liabilities are recorded at their undiscounted value.

In January 2015, the Company entered into a retroactive reinsurance contract to transfer the risk of loss of certain insurance reserves for workers’ compensation claims incurred from 2006 to 2011 to a reinsurer. Pursuant to the reinsurance contract, the reinsurer is obligated to pay an aggregate maximum of $17.5 million for these claims with any excess borne by the Company. The Company maintains the insurance reserves related to these claims as a liability on its consolidated balance sheet with an offsetting reinsurance receivable, which includes current and long-term components. As of December 31, 2018 and 2017, the carrying value of the insurance reserves related to these claims and the offsetting reinsurance receivable was $3.7 million and $4.5 million, respectively. Changes in these claims are recorded as an increase or decrease in the insurance reserves and corresponding increase or decrease in the reinsurance receivable. Additionally, the Company monitors the financial condition of the reinsurer to minimize its exposure to significant losses from reinsurer insolvency.

Retirement savings program

The Company sponsors a defined contribution retirement savings plan. The Company has recorded expense of $5.9 million, $5.2 million and $4.6 million related to employer contributions for the years ended December 31, 2018, 2017 and 2016, respectively. These expenses are recorded to either selling, general and administrative expenses or cost of sales on the consolidated statements of operations, depending on the classification of the employee.

Lease obligations

The Company recognizes lease obligations with fixed escalations of rental payments on a straight-line basis over the lease term, with the amount of rental expense in excess of lease payments recorded as a deferred rent liability. Lease incentives received are also recorded as a deferred rent liability and are amortized as reductions to rent expense over the lease term. As of December 31, 2018 and 2017, the Company had a deferred rent liability of $5.0 million and $4.2 million, respectively, included in accrued expenses and other liabilities and other long-term liabilities on the consolidated balance sheets.

Advertising and promotion

Costs associated with advertising and promoting products and services are expensed in the period incurred. Cooperative advertising allowances that are reimbursement of specific, incremental and identifiable costs incurred to promote vendors’ products are recorded as an offset against advertising expenses in selling, general and administrative expenses. If those conditions are not met, the cooperative advertising allowances are recorded as a reduction in inventory and a subsequent reduction in cost of goods sold when the related product is sold. For the years ended December 31, 2018, 2017 and 2016, the Company recorded $4.9 million, $5.8 million and $3.7 million, respectively, of advertising and promotion expenses, net of cooperative advertising allowances, in selling, general and administrative expenses.

Stock-based compensation

In accordance with the requirements of ASC 718, Compensation—Stock Compensation(“ASC 718”), the Company measures and recognizes compensation expense for all share-based payment awards made to employees using a fair value based pricing model. The compensation expense is recognized over the requisite service period, using graded vesting.

Debt issuance costs

Costs incurred in connection with the Company’s revolving line of credit and senior secured notes are capitalized and amortized over the term of the applicable agreement. Total debt issuance costs, net of accumulated amortization, were $6.4 million and $8.1 million as of December 31, 2018 and 2017, respectively. Debt issuance costs related to the Company’s revolving line of credit and senior secured notes are included in other long-term assets and long-term debt, respectively, on the consolidated balance sheets. Amortization of debt issuance costs for the years ended December 31, 2018, 2017 and 2016 was $1.7 million, $1.7 million and $3.1 million, respectively, and is included in interest expense on the consolidated statements of operations.

Derivatives

The Company will occasionally enter into derivative instruments to offset existing or expected risks associated with fluctuations in commodity prices. The Company does not enter into derivative instruments for speculative or trading purposes. The Company recognizes all derivative instruments as assets or liabilities in the Company’s balance sheets at fair value. Changes in the fair value of derivative instruments that are not designated as hedges or that do not meet the hedge accounting criteria are reported in earnings. The Company elected not to designate any new derivative instruments as hedges for the years ended December 31, 2018, 2017 or 2016, and therefore, all changes in the fair market value of the derivative instruments have been reported in cost of goods sold on the consolidated statements of operations.

Warranty expense

The Company has warranty obligations with respect to most manufactured products. As of December 31, 2018 and 2017, the Company had warranty liabilities of $2.9 million and $2.5 million, respectively, included in accrued expenses and other liabilities on the consolidated balance sheets.

Comprehensive income

Comprehensive income is equal to the net income for all periods presented.

Statement of cash flows

Proceeds from revolving line of credit and Repayments of proceeds from revolving line of credit as presented on the Consolidated Statements of Cash Flows includes all cash activities and transactions between the Company and its associated lenders in relation to the revolving line of credit, excluding interest and fees, and is specifically inclusive of operating cash receipts which are automatically applied to the revolving line of credit pursuant to a cash sweep agreement. See Note 9 for further details on the Company’s revolving line of credit.

Recently adopted accounting pronouncements

In May 2014, the FASB issued Topic 606. Topic 606 provides a comprehensive revenue recognition model requiring companies to recognize revenue for the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. The guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. The Company adopted Topic 606 on January 1, 2018 using the modified retrospective transition method. See Note 11 for further details.

In August 2016, the FASB issued Accounting Standards Update 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). ASU 2016-15 was issued to decrease the diversity in practice of how certain cash receipts and cash payments are presented and classified in the statement of cash flows by providing guidance on eight specific cash flow issues. Retrospective application is required. ASU 2016-15 became effective for the Company’s annual and interim periods beginning on January 1, 2018. The adoption of the standard did not have a material impact on the Company’s consolidated financial statements.

In November 2016, the FASB issued Accounting Standards Update 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (“ASU 2016-18”). ASU 2016-18 requires that the statement of cash flows include restricted cash in the beginning and end-of-period total amounts shown and that the statement of cash flows explain the changes in restricted cash during the period. Retrospective application is required. ASU 2016-18 became effective for the Company’s annual and interim periods beginning on January 1, 2018. The adoption of the standard did not have a material impact on the Company’s consolidated financial statements.

In January 2017, the FASB issued Accounting Standards Update 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business (“ASU 2017-01”). ASU 2017-01 provides guidance in determining when a set of assets and activities meets the definition of a business. Prospective application is required. ASU 2017-01 became effective for the Company’s annual and interim periods beginning on January 1, 2018. The adoption of the standard did not have a material impact on the Company’s consolidated financial statements.

In February 2017, the FASB issued Accounting Standards Update 2017-05, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets (“ASU 2017-05”). ASU 2017-05 clarifies the scope of Subtopic 610-20, which provides guidance for recognizing gains and losses from the sale or transfer of nonfinancial assets in contracts with noncustomers. ASU 2017-05 also provides guidance for partial sales of nonfinancial assets. ASU 2017-05 became effective for the Company’s annual and interim periods beginning on January 1, 2018. The adoption of the standard did not have a material impact on the Company’s consolidated financial statements.

In May 2017, the FASB issued Accounting Standards Update 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting (“ASU 2017-09”). ASU 2017-09 provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting under ASC 718. ASU 2017-09 is to be applied prospectively to an award modified on or after the adoption date. ASU 2017-09 became effective for the Company’s annual and interim periods beginning on January 1, 2018. The adoption of the standard did not have a material impact on the Company’s consolidated financial statements.

In March 2018, the FASB issued Accounting Standards Update 2018-05, Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118 (“ASU 2018-05”). ASU 2018-05 adds paragraphs to the ASC pursuant to SEC Staff Accounting Bulletin No. 118, which addresses the application of U.S. GAAP in situations when a company does not have the necessary information available, prepared or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Cuts and Jobs Act (the “2017 Tax Act”). ASU 2018-05 provides entities with a one year measurement period from the December 22, 2017 enactment date in order to complete the accounting. The Company recognized a provisional net tax benefit of $3.6 million related to the impact of the 2017 Tax Act during the year ended December 31, 2017. In the fourth quarter of 2018, the Company completed its accounting for the income tax effects of the 2017 Tax Act within the measurement period as provided under ASU 2018-05, which resulted in recognizing an additional tax benefit of $0.5 million for the year ended December 31, 2018.

Recently issued accounting pronouncements not yet adopted

In February 2016, the FASB issued Accounting Standards Update 2016-02, Leases, and issued subsequent amendments to the initial guidance to provide additional clarification on specific topics (“ASU 2016-02”). ASU 2016-02 establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the statement of operations. The Company plans to adopt the standard on January 1, 2019, utilizing the transition option provided by Accounting Standards Update 2018-11, Leases (Topic 842): Targeted Improvements, which the FASB issued in July 2018 and allows the Company to apply the guidance in ASU 2016-02 as of the adoption date, while applying the legacy guidance in ASC 840, Leases, including its disclosure requirements, in the comparative periods. As a lessee, certain of the Company’s leases under existing guidance are classified as operating leases that are not recorded on the balance sheet but are recorded in the statement of operations as expense is incurred. Upon adoption of the standard, the Company will be required to record substantially all leases on the balance sheet as a ROU asset and a lease liability. The Company expects to utilize the package of practical expedients permitted by the transition guidance in ASU 2016-02, which allows the Company to carry forward its identification of contracts that are or contain leases, its historical lease classification and its initial direct costs for existing leases. The Company currently expects to recognize lease liabilities for its operating leases totaling between $110.0 million and $125.0 million upon adoption, of which between $22.0 million and $37.0 million will be classified as a current liability. The initial ROU assets recognized will be equal to the initial operating lease liabilities, adjusted for the balance on adoption date of prepaid and accrued rent, lease incentives, unamortized initial direct costs and unamortized assets and liabilities related to favorable and unfavorable lease terms. The Company currently expects to recognize ROU assets totaling between $105.0 million and $120.0 million upon adoption. The Company does not expect adoption of the standard to have a material impact on the Company’s historical capital leases, which will be presented as finance leases under ASU 2016-02. See Note 13 for further information on the Company’s leases.

In June 2016, the FASB issued Accounting Standards Update 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 amends the impairment model by requiring entities to use a forward-looking approach based on expected losses to estimate credit losses on certain types of financial instruments, including trade receivables. ASU 2016-13 is effective for the Company’s annual and interim periods beginning on January 1, 2020, with early adoption permitted beginning January 1, 2019. Modified retrospective application is required, with certain exceptions. The Company expects to adopt the standard on January 1, 2020 and continues to evaluate the impact of the standard on its consolidated financial statements.

In January 2017, the FASB issued Accounting Standards Update 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). ASU 2017-04 simplifies the accounting for goodwill impairment by removing Step 2 of the goodwill impairment test, which requires computation of the implied fair value of a reporting unit’s goodwill. The amount of a goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. ASU 2017-04 is effective for the Company’s annual goodwill impairment test and any interim tests during the Company’s annual and interim periods beginning on January 1, 2020. Early adoption is permitted for goodwill impairment tests performed on testing dates after January 1, 2017. Prospective application is required. The adoption of the standard is not expected to have a material impact on the Company’s consolidated financial statements.

In August 2018, the FASB issued Accounting Standards Update 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, and issued subsequent amendments to the initial guidance to provide additional clarification on specific topics (“ASU 2018-13”). ASU 2018-13 modifies the disclosure requirements on fair value measurements by removing, modifying and adding certain disclosure requirements in ASC 820. ASU 2018-13 is effective for the Company’s annual and interim periods beginning on January 1, 2020, with early adoption permitted. Certain disclosures in ASU 2018-13 are required to be applied prospectively, while others require retrospective application. The Company is evaluating the impact of the standard on its consolidated financial statements.

Business Combinations [Abstract]

Acquisitions and disposition

Acquisitions and Disposition

For all acquisitions, the Company allocates the purchase price to assets acquired and liabilities assumed as of the date of acquisition based on the estimated fair values at the date of acquisition. The excess of the fair value of the purchase consideration over the fair values of the identifiable assets and liabilities is recorded as goodwill. Management makes significant estimates and assumptions when determining the fair value of assets acquired and liabilities assumed. These estimates include, but are not limited to, discount rates, projected future net sales, projected future expected cash flows and useful lives.

The Company accounts for all acquisitions using the acquisition method of accounting under ASC 805, Business Combinations (“ASC 805”), whereby the results of operations of the acquired company are included in the Company’s consolidated financial statements beginning on the acquisition date.

2018 Disposition

On November 1, 2018, the Company completed the sale of substantially all of the assets and certain liabilities of its Coleman Floor business (“Coleman Floor”) for a preliminary sale price of $7.8 million, subject to certain customary post-closing adjustments. For the year ended December 31, 2018, the net sales of Coleman Floor represented approximately 1% of the Company’s net sales. The sale does not represent a strategic shift under ASC 205, Presentation of Financial Statements, and as such, is not reported as a discontinued operation in the Company’s consolidated financial statements. The Company recognized a loss on the sale of $0.3 million, which is included in other income, net in the consolidated statements of operations.

2018 Acquisition

On March 1, 2018, the Company acquired substantially all of the assets and assumed certain liabilities of W.E. Shone Co. (“Shone Lumber”), a supplier of building materials in the state of Delaware, for a preliminary purchase price of $22.4 million. This acquisition enhances the Company’s value-added offerings and footprint in the Mid-Atlantic region. The preliminary purchase price includes a holdback which, after certain post-closing adjustments, requires the Company to pay $1.4 million to the sellers one year from the closing date. The holdback amount may be further reduced under certain circumstances. The Company funded the transaction through available cash and borrowings on the Company’s revolving line of credit.

The purchase price allocation resulted in the recognition of goodwill of $2.5 million, a customer relationship intangible asset of $7.0 million, accounts receivable of $6.4 million, inventory of $8.8 million, property and equipment of $2.9 million and total current liabilities of $5.3 million, as well as other operating assets. The customer relationship intangible asset has a useful life of 9 years. Goodwill represents the future economic benefits expected to arise from other intangible assets acquired that do not qualify for separate recognition, including assembled workforce and non-contractual relationships, as well as expected future synergies. All of the goodwill recognized is expected to be deductible for tax purposes.

For the year ended December 31, 2017, Shone Lumber generated net sales of approximately $70.7 million. The Company incurred transaction costs of $0.2 million for the year ended December 31, 2018, which are included in selling, general and administrative expenses in the consolidated statements of operations.

Net sales and estimated pre-tax earnings for Shone Lumber included in the consolidated statements of operations from the March 1, 2018 acquisition date to December 31, 2018 were $60.9 million and $3.2 million, respectively. The impact of the acquisition was not considered significant for the reporting of pro forma financial information.

2017 Acquisitions

On April 3, 2017, the Company acquired substantially all of the assets and assumed certain liabilities of Texas Plywood & Lumber Company, Inc. (“TexPly”), a supplier of production millwork and doors in the Dallas-Fort Worth area, for a purchase price of $31.7 million. This acquisition enhances the Company’s value-added offerings and footprint in the Dallas-Fort Worth market. The Company funded the transaction through borrowings on the Company’s revolving line of credit.

The purchase price allocation resulted in the recognition of goodwill of $3.6 million, a customer relationship intangible asset of $13.6 million, accounts receivable of $5.2 million, inventory of $3.9 million and real property of $5.4 million, as well as other operating assets and liabilities. The customer relationship intangible asset has a useful life of 13 years. Goodwill represents the future economic benefits expected to arise from other intangible assets acquired that do not qualify for separate recognition, including assembled workforce and non-contractual relationships, as well as expected future synergies. All of the goodwill recognized is expected to be deductible for tax purposes.

On March 27, 2017, the Company acquired substantially all of the assets and assumed certain liabilities of Code Plus Components, LLC (“Code Plus”), a manufacturer of structural components located in Martinsburg, West Virginia, for a purchase price of $7.1 million. This acquisition allowed the Company to add truss manufacturing capability to its value-added offerings in the Washington, DC metro area. The acquisition includes an earnout provision that requires the Company to pay the sellers an additional $0.8 million during the year ended December 31, 2019, due to the acquired operations achieving certain performance targets from the acquisition date through December 31, 2018. The Company funded the transaction through borrowings on the Company’s revolving line of credit.

The purchase price allocation resulted in the recognition of goodwill of $3.4 million, a customer relationship intangible asset of $2.3 million and a non-compete agreement intangible asset of $0.5 million, as well as other operating assets and liabilities. The customer relationship intangible asset and non-compete agreement intangible asset have useful lives of 12 years and 5 years, respectively. Goodwill represents the future economic benefits expected to arise from other intangible assets acquired that do not qualify for separate recognition, including assembled workforce and non-contractual relationships, as well as expected future synergies. All of the goodwill recognized is expected to be deductible for tax purposes.

Net sales and estimated pre-tax earnings for Code Plus and TexPly, in aggregate, included in the consolidated statements of operations were $54.3 million and $3.2 million, respectively, for the year ended December 31, 2017. The impact of the Code Plus and TexPly acquisitions was not considered significant for the reporting of pro forma financial information.

Impairment of BMHC ERP System

During 2013, BMHC selected a new third-party software vendor for its planned Enterprise Resource Planning (“New ERP”) system and began incurring costs related to design, development and implementation of the New ERP. BMHC also began paying an annual licensing fee. During March 2016, the Company decided to integrate all operations under the Enterprise Resource Planning system utilized by Legacy SBS (the “Legacy SBS ERP system”) and to discontinue the use of the New ERP. In connection with this decision, the Company recorded asset impairment charges of approximately $11.9 million in its consolidated statement of operations for the year ended December 31, 2016 related to capitalized software development costs for New ERP functionality that the Company had intended to implement in future periods. These costs had previously been recorded as construction-in-progress within property and equipment on the consolidated balance sheets.

During the year ended December 31, 2017, the Company determined that it had ceased receiving economic benefit from certain non-cancellable license and service contracts related to the New ERP. In accordance with ASC 420, Exit or Disposal Cost Obligations, as of the cease use date, the Company recognized approximately $2.8 million of expense within Merger and integration costs in its consolidated statements of operations for the year ended December 31, 2017, consisting of $2.1 million for contractual payments due subsequent to the cease use date, all of which have been paid as of December 31, 2017, and the acceleration of expense recognition of unamortized prepaid costs of $0.7 million.

Senior secured notes

On September 15, 2016, the Company issued $350.0 million of senior secured notes due 2024 (the “Senior Notes”) under an unregistered private placement not subject to the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”). The Senior Notes are governed by an indenture dated September 15, 2016 (the “Indenture”). The Senior Notes were issued by BMC East, LLC, a 100% owned subsidiary of the Company, and are guaranteed by the Company and the other subsidiaries that guarantee the Credit Agreement (as defined below). Each of the subsidiary guarantors is 100% owned, directly or indirectly, by the Company, and all guarantees are full and unconditional and joint and several. The Senior Notes mature on October 1, 2024 and are secured by a first priority lien on certain assets of the Company and a second priority lien on the collateral that secures the Credit Agreement on a first-priority basis, which collectively accounts for substantially all assets of the Company. The interest rate is fixed at 5.5% and is payable semiannually on April 1 and October 1.

The Indenture contains customary nonfinancial covenants, including restrictions on new indebtedness, issuance of liens and guarantees, investments, distributions to equityholders, asset sales and affiliate transactions. At any time prior to October 1, 2019, the Company may redeem the Senior Notes in whole or in part at a price equal to 100% of the principal, plus accrued and unpaid interest, plus the greater of (a) 1% of the principal amount of such Senior Note and (b) on any redemption date, the excess (to the extent positive) of the present value of the redemption price of such Senior Note at October 1, 2019 (equal to 104.125%) plus all required interest payments due on such Senior Note to and including October 1, 2019 (excluding accrued but unpaid interest), computed upon the redemption date using a discount rate equal to the applicable treasury rate, as defined in the Indenture, at such redemption date plus 50 basis points, over the outstanding principal amount of such Senior Note. Further, during any twelve month period prior to October 1, 2019, the Company may redeem up to 10% of the Senior Notes at a redemption price equal to 103% plus accrued and unpaid interest. At any time on or after October 1, 2019, the Company may redeem the Senior Notes in whole or in part at the redemption prices set forth in the Indenture plus accrued and unpaid interest. In addition, at any time prior to October 1, 2019, the Company may redeem up to 40% of the aggregate principal amount of the Senior Notes with the net cash proceeds of one or more equity offerings, as described in the Indenture, at a price equal to 105.5% plus accrued and unpaid interest. If the Company experiences certain change of control events, holders of the Senior Notes may require the Company to repurchase all or part of their Senior Notes at a price equal to 101% plus accrued and unpaid interest. The Company was in compliance with all debt covenants under the Indenture as of December 31, 2018.

The net cash proceeds from the Senior Notes were used to redeem in full $250.0 million of 9.0% senior secured notes that were issued by BMHC in September 2013 and which were scheduled to mature in September 2018 (the “Extinguished Senior Notes”), and to pay accrued interest on the Extinguished Senior Notes of $11.3 million. In connection with the redemption of the Extinguished Senior Notes, the Company incurred a loss on debt extinguishment of $12.5 million, consisting of a call premium of $8.4 million, and the write off of unamortized debt issuance costs and original issue discount of $4.1 million. The remaining proceeds were used to repay outstanding borrowings on the Revolver (as defined below) and to pay debt issuance costs of $6.7 million, which will be amortized over the term of the Senior Notes.

As of December 31, 2018, the estimated market value of the Senior Notes was $21.0 million lower than the carrying amount. The fair value is based on institutional trading activity and was classified as a Level 2 measurement in accordance with ASC 820.

Revolving credit agreement

On December 1, 2015, in connection with the Merger, the Company entered into a senior secured credit agreement with Wells Fargo Capital Finance, as administrative agent, and certain other lenders (the “Original Credit Agreement”) which includes a revolving line of credit (the “Revolver”). On September 15, 2016, the Company entered into the second amendment to the Credit Agreement (the “Second Amendment” and, the Original Credit Agreement as amended by the Second Amendment, the “Credit Agreement”), which reduced the aggregate commitment from $450.0 million to $375.0 million and increased the letters of credit commitment from $75.0 million to $100.0 million. The Revolver is subject to an asset-based borrowing formula on eligible accounts receivable, credit card receivables and inventory, in each case reduced by certain reserves.

Borrowings under the Revolver bear interest, at the Company’s option, at either the Base Rate (which means the higher of (i) the Federal Funds Rate plus 0.5%, (ii) the LIBOR rate plus 1.0% or (iii) the prime rate) plus a Base Rate Margin (which ranges from 0.25% to 0.75% based on Revolver availability) or LIBOR plus a LIBOR Rate Margin (which ranges from 1.25% to 1.75% based on Revolver availability).

The fee on any outstanding letters of credit issued under the Revolver ranges from 0.75% to 1.25%, depending on whether the letters of credit are fully cash collateralized. The fee on the unused portion of the Revolver is 0.25%. The Credit Agreement contains customary nonfinancial covenants, including restrictions on new indebtedness, issuance of liens, investments, distributions to equityholders, asset sales and affiliate transactions. The Credit Agreement includes a financial covenant that requires us to maintain a Fixed Charge Coverage Ratio, as defined therein, of at least 1.00:1:00, at the end of any fiscal quarter during the period from the date that Excess Availability, as defined therein, under the Credit Agreement is less than or equal to the greater of (1) $33.3 million and (2) 10% of the line cap, and remains in effect until excess availability has been greater than the greater of (1) $33.3 million and (2) 10% of the line cap for a period of at least 30 consecutive days.

The Revolver matures at the earlier of (i) December 1, 2020 and (ii) the date that is three months prior to the maturity of the Senior Notes, or if the Senior Notes are refinanced or repaid, the date that is three months prior to the new maturity date of the replacement notes or other indebtedness that replaced or refinanced the Senior Notes. Due to the redemption of the Extinguished Senior Notes during September 2016, the issuance of the Senior Notes which mature on October 1, 2024 and the Company entering into the Second Amendment, the effective maturity date of the Revolver was extended from June 15, 2018, the date three months prior to the maturity date of the Extinguished Senior Notes, to December 1, 2020. After considering the increase to the remaining term and the reduction of the aggregate commitment resulting from the Second Amendment, the overall borrowing capacity of the Revolver increased. Accordingly, all existing unamortized debt issuance costs and new debt issuance costs related to the Second Amendment are being amortized through December 1, 2020. The Company was in compliance with all debt covenants under the Credit Agreement as of December 31, 2018.

The Company had no outstanding borrowings under the Revolver with net availability of $309.5 million as of December 31, 2018. The Company had $61.0 million in letters of credit outstanding under the Credit Agreement as of December 31, 2018. Obligations under the Credit Agreement are guaranteed by the Company’s material subsidiaries. Obligations under the Credit Agreement and the guarantees of those obligations, are secured by substantially all of the Company’s assets and those of the guarantors, subject to certain exceptions and permitted liens, including a first-priority security interest in certain accounts receivable, inventory and certain other assets of the Company and a second-priority security interest in substantially all other assets of the Company that secure the Senior Notes on a first-priority basis.

Adoption of Topic 606

On January 1, 2018, the Company adopted Topic 606 using the modified retrospective method applied to those contracts that were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with the Company’s historical accounting policy under Topic 605, Revenue Recognition.

The impact of adopting Topic 606 was not material to the Company’s results of operations for the year ended December 31, 2018 and as such, comparability between periods is not materially affected.

Beginning January 1, 2018, the Company has presented contract assets and contract liabilities on its consolidated balance sheets, determined on a contract-by-contract basis. Contract assets contain rights to payment that are conditional on something other than the passage of time, such as retainage, which were historically presented within accounts receivable, net of allowances, as well as the balances that were historically presented within costs in excess of billings on uncompleted contracts on the Company’s consolidated balance sheets. Contract liabilities contain advances from customers, which were historically presented within accrued expenses and other liabilities, as well as the balances that were historically presented within billings in excess of costs on uncompleted contracts on the Company’s consolidated balance sheets. Refer to further discussion of the Company’s contract assets and contract liabilities below.

Additionally, beginning January 1, 2018, the Company has presented a return asset, which represents inventory the Company expects to receive from customers related to estimated sales returns, within prepaid expenses and other current assets on the Company’s consolidated balance sheets. This balance was previously presented within inventories, net, on the Company’s consolidated balance sheets. Conversely, the Company has recorded a refund liability for estimated returns of inventory within accrued expenses and other liabilities on the Company’s consolidated balance sheets. These balances were previously presented as an allowance within accounts receivable, net of allowances, on the Company’s consolidated balance sheets.

The following table reflects the cumulative impact of adoption of Topic 606. As the cumulative impact of adopting Topic 606 on the Company’s historical results of operations was less than $0.1 million, the Company did not record an adjustment to opening retained earnings as of January 1, 2018.

Disaggregation of revenue

The following table presents the Company’s net sales disaggregated by customer type. See Note 15 to the consolidated financial statements for a disaggregation of the Company’s net sales by main product lines. As noted above, prior period amounts have not been adjusted under the modified retrospective method and continue to be reported in accordance with the Company’s historic accounting policy under Topic 605.

The following table reflects the Company’s estimate of net sales by each customer type for the years ended December 31, 2018, 2017 and 2016. Certain previously reported amounts for interim periods during the year ended December 31, 2018 and for the year ended December 31, 2017 were revised in the table below. The revisions were not material to the previously issued financial statements.

Contract balances

The following table reflects the Company’s contract balances as of December 31, 2018 and January 1, 2018, the date that the Company adopted Topic 606:

Contract assets	32,348		38,557		(6,209		)
Contract liabilities	$	34,888	$	26,330	$	8,558

During the year ended December 31, 2018, the Company’s contract assets decreased by $6.2 million and the Company’s contract liabilities increased by $8.6 million. The change in contract assets and liabilities was primarily due to the timing of revenue recognition, as the balances were not materially impacted by any other factors. For the year ended December 31, 2018, the Company recognized revenue of $25.1 million, that was included in contract liabilities as of January 1, 2018. Revenue recognized related to performance obligations that were satisfied or partially satisfied in previous periods was not material for the year ended December 31, 2018.

Practical expedients

As permitted by Topic 606, the Company has elected to expense any incremental costs of obtaining a contract as incurred as the amortization period would have been one year or less. Additionally, as permitted by Topic 606, the Company has elected not to adjust the promised amount of consideration for a significant financing component as the Company expects that the period of time between the Company’s satisfaction of the performance obligation and the customer’s payment would have been one year or less. Finally, as permitted by Topic 606, the Company has elected not to disclose the value of unsatisfied performance obligations, as the Company’s contracts generally have an original expected length of one year or less.

A reconciliation of differences between the statutory U.S. federal income tax rate and the Company’s effective tax rate from continuing operations for the years ended December 31, 2018, 2017 and 2016 follows:

Other items	—		(0.2	)	0.5
Effective tax rate	23.7	%	29.8	%	31.6	%

On December 22, 2017, the 2017 Tax Act was enacted, which significantly changed U.S. tax law effective January 1, 2018 by, among other things, lowering corporate income tax rates from 35% to 21%, eliminating Internal Revenue Code (“IRC”) Section 199 manufacturing deduction, accelerating tax depreciation on certain acquired assets, further limiting executive compensation, and creating certain interest deduction limitations. The Securities and Exchange Commission staff issued Staff Accounting Bulletin No. 118 to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the 2017 Tax Act. The Company recognized a net tax benefit of $3.6 million during the year ended December 31, 2017 related to the impact of the 2017 Tax Act for the remeasurement of deferred tax assets and liabilities. During the year ended December 31, 2018, the Company completed its accounting for the income tax effects of the 2017 Tax Act within the measurement period as provided under SEC Staff Accounting Bulletin No. 118, which resulted in recognizing an additional tax benefit of $0.5 million.

For the year ended December 31, 2018, the Company recognized $37.2 million of income tax expense, which included an income tax benefit of $0.5 million related to the 2017 Tax Act. The Company’s effective tax rate for the year ended December 31, 2018 was higher than the Company’s federal and state statutory rates primarily due to nondeductible expenses.

For the year ended December 31, 2017, the Company recognized $24.4 million of income tax expense, which included an income tax benefit of $3.6 million related to the 2017 Tax Act. The Company’s effective tax rate for the year ended December 31, 2017 was lower than the federal and state statutory rates primarily due to the effects of the 2017 Tax Act, an IRC Section 199 manufacturing deduction and excess windfall tax benefits of stock compensation deductions.

For the year ended December 31, 2016, the Company recognized $14.3 million of income tax expense, which included an income tax benefit of $1.7 million as a result of the Company adopting a state tax position related to IRC section 382 limitations on a state net operating loss carry-forward. For the year ended December 31, 2016, the Company’s effective tax rate, excluding the state tax position change, was lower than the Company’s federal and state statutory rates primarily due to excess windfall tax benefits of stock compensation deductions and an IRC section 199 manufacturing deduction.

As of December 31, 2018, due to IRC section 382 limitations, the Company estimates federal net operating loss carryforwards generated prior to November 2011 will be limited to approximately $4.8 million per year through 2034. These net operating losses may generally be carried forward 20 years. As a result, federal operating losses if unused will expire as follows:

• $29.4 million in 2028;

• $17.3 million in 2029; and

• $31.2 million in years 2030 through 2034.

In addition, as of December 31, 2018, the Company had $75.1 million of state net operating loss carryforwards that expire at various dates commencing in 2022 through 2035.

The Company recognized tax benefits of $0.3 million and $1.9 million during 2018 and 2017, respectively, from stock-based compensation deductions into its income tax expense. Deferred tax assets relating to tax benefits of stock-based compensation were reduced to reflect exercises or vesting; however, some exercises or vesting resulted in tax deductions in excess of previously recorded deferred tax benefits (“windfalls”). Prior to the adoption of ASU 2016-09, Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, windfall tax benefits were recognized as a component of shareholders’ equity, which included $0.4 million for December 31, 2016.

The Company recognized a current income tax payable of $0.9 million and an income tax receivable of $3.7 million as of December 31, 2018 and 2017, respectively. The Company paid federal and state income tax payments of $34.2 million and $23.5 million during 2018 and 2017, respectively. The Company received tax refunds of $2.9 million and $0.6 million in 2018 and 2017, respectively.

In accordance with ASC 740, the Company evaluates its deferred tax assets to determine if valuation allowances are required. In assessing the realizability of deferred tax assets, the Company considers both positive and negative evidence in determining whether it is more likely than not that some portion or all of the deferred tax assets will not be realized.

As of December 31, 2018 and 2017, the primary positive evidence considered to support the realization of the Company’s deferred tax assets includes: (i) the cumulative pre-tax income over the last 36 months, (ii) the reversal of deferred tax liabilities related to depreciation and amortization that would occur within the same jurisdiction and during the carry forward period necessary to absorb the federal and state net operating losses and other deferred tax assets, (iii) current and prior year utilization of federal and state net operating losses, and (iv) no history of material expiring tax attributes. The primary negative evidence considered includes: (i) the Company’s cumulative losses prior to 2013, (ii) unsettled circumstances associated with the general economy and housing market, as well as mortgage credit availability, and (iii) no federal and state net operating loss carryback opportunities. To the extent the Company generates future net operating losses, the Company may be required to increase the valuation allowance on its deferred tax assets and income tax benefit would be adversely affected.

Based upon the positive and negative evidence considered, the Company believes it is more likely than not that it will realize the benefit of the deferred tax assets, net of the existing state tax valuation allowances of $0.1 million as of December 31, 2018 and 2017. To the extent the Company generates sufficient taxable income in the future to fully utilize the tax benefits of the net deferred tax assets on which a valuation allowance was recorded, the Company’s effective tax rate would be impacted as the valuation allowance is reversed. The Company continues to evaluate its deferred tax asset on a quarterly basis and notes that, if economic conditions were to change such that the Company earns less taxable income than the amounts required to fully utilize its deferred tax asset, a portion of the asset may expire unused.

The following table shows the changes in the amount of the Company’s valuation allowance:

(in thousands)	2018		2017		2016
Balance at January 1,	$	145	$	125	$	126

Additions charged to Goodwill/Purchase Accounting	—		—		—
Deductions - other	—		—		(1		)
Balance at December 31,	$	145	$	145	$	125

The Company has no material uncertain tax positions as of December 31, 2018 and 2017.

The Company’s state tax returns are open to examination for an average of three years. However, certain jurisdictions remain open to examination longer than three years due to the existence of net operating losses. The Company’s federal returns are open to examination for three years; however, due to statutory waivers, SBS’ tax years ended July 31, 2008 and May 5, 2009 remain open until July 31, 2020 with the federal tax authorities. SBS is currently under examination by the IRS for its tax years ended July 31, 2008 and May 5, 2009. At December 31, 2018 and 2017, the amount recognized related to expected tax, penalties and interest payments as a result of the IRS audits in income taxes payable and income taxes receivable, respectively, on the consolidated balance sheets was immaterial.

The Company’s policy is to recognize interest and penalties related to income tax liabilities and unrecognized tax benefits in income tax expense. During the years ended December 31, 2018, 2017 and 2016, penalties and interest related to income tax liabilities and uncertain tax benefits were not material.

Commitments and Contingencies

Commitments and Contingencies

The Company is obligated under capital leases covering fleet vehicles and certain equipment, as well as certain facilities. The fleet vehicles and equipment leases generally have terms ranging from three to six years and the facility leases have a remaining term of four to five years. The carrying value of property and equipment under capital leases was $17.2 million and $25.2 million at December 31, 2018 and 2017, respectively, net of accumulated depreciation of $42.5 million and $37.1 million, respectively. Amortization of assets held under capital leases is included within depreciation expense or cost of goods sold on the consolidated statements of operations.

The Company also has noncancelable operating leases, primarily for buildings, improvements and equipment. These leases generally contain renewal options for periods ranging from one to five years and may require the Company to pay executory costs such as property taxes, maintenance and insurance.

Future minimum lease payments under noncancelable operating leases (with initial or remaining lease terms in excess of one year) and future minimum capital lease payments as of December 31, 2018 are as follows:

Long-term capital lease obligation	$	8,845

(a) Minimum operating lease payments have not been reduced by minimum sublease rentals of $0.1 million due in the future under noncancelable subleases.    

Total rent expense under operating leases, excluding short-term rentals, for the years ended December 31, 2018, 2017 and 2016 was $32.2 million, $30.5 million and $29.3 million, respectively, which are included in either cost of sales or selling, general and administrative expenses on the consolidated statements of operations, depending on the type of operations undertaken by the related facility or asset. Future payments for certain leases will be adjusted based on increases in the consumer price index.

As of December 31, 2018, the Company had purchase commitments totaling $31.6 million related primarily to vehicles and certain IT equipment, which are enforceable and legally binding on the Company.

From time to time, various claims, legal proceedings and litigation are asserted or commenced against the Company principally arising from alleged product liability, warranty, casualty, construction defect, contract, tort, employment and other disputes. In determining loss contingencies, management considers the likelihood of loss as well as the ability to reasonably estimate the amount of such loss or liability. An estimated loss is recorded when it is considered probable that such a liability has been incurred and when the amount of loss can be reasonably estimated. It is not certain that the Company will prevail in these matters. However, the Company does not believe that the ultimate outcome of any pending matters will have a material adverse effect on its consolidated financial position, results of operations or cash flows. As of December 31, 2018 and 2017, the Company has accrued $3.0 million in relation to pending litigation that was recorded within selling, general and administrative expenses in its statements of operations during the year ended December 31, 2017.

Stock Based Compensation

Stock Based Compensation

Long-term incentive plan

In connection with its initial public offering in August 2013, SBS adopted the Stock Building Supply Holdings, Inc. 2013 Incentive Compensation Plan (“SBS 2013 Incentive Plan”). The SBS 2013 Incentive Plan provides for grants of stock options, stock appreciation rights, restricted stock, other stock-based awards, other cash-based compensation and performance awards. In general, if awards under the SBS 2013 Incentive Plan are for any reason canceled, or expire or terminate unexercised, the shares covered by such awards may again be available for the grant of awards under the SBS 2013 Incentive Plan. Awards granted under the SBS 2013 Incentive Plan generally vest over a period of three or four years. Stock options granted under the SBS 2013 Incentive Plan have a maximum contractual term of 10 years from the date of grant. As of December 31, 2018, 2.4 million shares were available for issuance under the SBS 2013 Incentive Plan.

Segment Reporting [Abstract]

Segments

Segments

ASC 280, Segment Reporting (“ASC 280”) defines operating segments as components of an enterprise about which separate financial information is available that is evaluated regularly by the CODM in deciding how to allocate resources and in assessing performance.

The Company’s five operating segments are the Mid-Atlantic, Southeast, Texas, Intermountain and Western divisions. The CODM reviews aggregate information to allocate resources and assess performance. Based on the CODM’s review, as well as the similar economic characteristics, nature of products, distribution methods and customers of the divisions, the Company has aggregated its operating segments into one reportable segment, “Geographic divisions.”

In addition to the Company’s reportable segment, the Company’s consolidated results include “Other reconciling items.” Other reconciling items comprises the Company’s corporate activities and other income and expenses not allocated to the operating segments.

The following tables present Net sales, Adjusted EBITDA and certain other measures for the reportable segment and total Company operations for the periods indicated. Adjusted EBITDA is used as a performance metric by the CODM in determining how to allocate resources and assess performance.

Earnings Per Share [Abstract]

Earnings Per Common Share

Earnings Per Share

Basic net income per share (“EPS”) is calculated by dividing net income attributable to common stockholders by the weighted average shares outstanding during the period. Diluted EPS is calculated by adjusting weighted average shares outstanding for the dilutive effect of potential common shares, determined using the treasury-stock method. For purposes of the diluted EPS calculation, stock options, restricted stock and restricted stock unit awards are considered to be potential common shares. Performance-based restricted stock units are not included in the calculation of diluted EPS until they are contingently issuable.

The basic and diluted EPS calculations for the years ended December 31, 2018, 2017 and 2016 are presented below:

The following table provides the securities that could potentially dilute EPS in the future, but were not included in the computation of diluted EPS for the periods presented because to do so would have been anti-dilutive. The amounts included in this table exclude performance-based restricted stock units. As of December 31, 2018, the number of currently outstanding performance-based restricted stock units that are issued upon vesting could range from zero to a maximum of 0.6 million.

Subsequent Events

On January 14, 2019, the Company acquired substantially all of the assets and assumed certain liabilities of Barefoot, a supplier of windows, exterior doors, hardware, specialty products and installation services in the Charlotte, North Carolina metropolitan area. On February 8, 2019, the Company acquired substantially all of the assets and assumed certain liabilities of Locust Lumber, a supplier of lumber products and building materials primarily to custom homebuilders and professional remodeling contractors in the Charlotte, North Carolina metropolitan area. These acquisitions enhance the Company’s value-added offerings and footprint in the Charlotte, North Carolina metropolitan area. The preliminary purchase price, in aggregate, for these acquisitions was $54.5 million, which includes an initial holdback of $2.5 million due to the sellers of Barefoot one year from the closing date. The holdback amount may be reduced under certain circumstances. The Company funded the transactions through available cash. For the year ended December 31, 2018, Barefoot and Locust Lumber generated net sales, in aggregate, of approximately $105 million.

The results of operations of Barefoot and Locust Lumber will be included in the Company’s consolidated financial statements beginning on the respective acquisition dates. Due to the timing of the close of the acquisitions, the initial purchase accounting for the acquisitions is not complete and therefore, certain disclosures required by ASC 805 have not been included. The Company is in the process of performing its valuation of the acquired assets and liabilities and currently anticipates customer relationship intangible assets and goodwill, among other operating assets and liabilities, to be recognized as part of these acquisitions.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of presentation

Basis of presentation

The accompanying consolidated financial statements have been prepared by management in conformity with U.S generally accepted accounting principles (“U.S. GAAP”).

Principles of consolidation

Principles of consolidation

The consolidated financial statements include all accounts of BMC and its wholly-owned subsidiaries. All material intercompany accounts and transactions have been eliminated in consolidation.

Use of estimates

Use of estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company evaluates these estimates and judgments on an ongoing basis and bases its estimates on historical experience, current conditions and various other assumptions that are believed to be reasonable under the circumstances. The results of these estimates form the basis for making judgments about the carrying values of assets and liabilities as well as identifying and assessing the accounting treatment with respect to commitments and contingencies. The significant estimates which could change by a material amount in the near term include revenue recognition for construction services, accounts receivable reserves, estimated losses on uncompleted contracts and changes in contract estimates, inventory reserves, supplier rebates, goodwill impairment, impairment of property and equipment, insurance reserves, warranties and share-based compensation. Actual results may differ materially from these estimates under different assumptions or conditions.

Business and credit concentrations

Business and credit concentrations

The Company maintains cash at financial institutions in excess of federally insured limits. Accounts receivable potentially expose the Company to concentrations of credit risk. Mitigating this credit risk is collateral underlying certain accounts receivable (perfected liens or lien rights) as well as the Company’s analysis of a customer’s credit history prior to extending credit. Concentrations of credit risk with respect to accounts receivable are limited due to the Company’s large number of customers and their dispersion across various regions of the United States. At December 31, 2018 and 2017, no customer represented more than 10% of accounts receivable. For the years ended December 31, 2018, 2017 and 2016, no customer accounted for more than 10% of revenue.

The Company’s future results could be adversely affected by a number of factors including competitive pressure on sales and pricing, weather conditions, consumer spending and debt levels, interest rates, existing residential home sales and new home construction, lumber prices and product mix.

Cash and cash equivalents

Cash and cash equivalents

Cash equivalents are highly liquid investments that are readily convertible to known amounts of cash and have a maturity of three months or less from the time of purchase. As of December 31, 2018 and 2017, the Company had cash equivalents of $146.1 million and $0, respectively. Cash equivalents are valued at amortized cost, which approximates fair value due to the short-term maturity of these instruments, and was classified as a Level 1 or Level 2 measurement in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 820, Fair Value Measurements and Disclosures (“ASC 820”).

Book overdrafts occur when purchases on corporate purchasing cards and checks written exceed available bank balances at a specific bank, despite there being cash at the Company’s other financial institutions. For accounting purposes, the Company reclassifies these book overdrafts to accounts payable on the consolidated balance sheets. Book overdrafts included in accounts payable were $0.1 million at December 31, 2018 and 2017.

Fair value of financial instruments

Fair value of financial instruments

ASC 820 clarifies the definition of fair value, prescribes methods for measuring fair value, and establishes a fair value hierarchy to classify the inputs used in measuring fair value as follows:

Level 1	Inputs are unadjusted quoted prices in active markets for identical assets or liabilities available at the measurement date.
Level 2	Inputs are unadjusted quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, inputs other than quoted prices that are observable, and inputs derived from or corroborated by observable market data.
Level 3	Inputs are unobservable inputs which reflect the reporting entity’s own assumptions on what assumptions the market participants would use in pricing the asset or liability based on the best available information.

If a financial instrument uses inputs that fall in different levels of the hierarchy, the instrument is categorized based upon the lowest level of input that is significant to the fair value calculation.

Accounts receivable

Accounts receivable

Accounts receivable result from the extending of credit to trade customers for the purchase of goods and services. The terms generally provide for payment within 30 days of being invoiced. On occasion, when necessary to compete in certain circumstances, the Company will sell product under extended payment terms. Accounts receivable are stated at estimated net realizable value. The allowance for doubtful accounts is based on an assessment of individual past due accounts, historical write-off experience, accounts receivable aging, customer disputes and the business environment. Account balances are charged off when the potential for recovery is considered remote. The Company grants trade discounts on a percentage basis. The Company records an allowance against accounts receivable for the amount of discounts it estimates will be taken by customers. The discounts are recorded as a reduction to revenue when products are sold.

Consideration received from suppliers

Consideration received from suppliers

The Company enters into agreements with many of its suppliers providing for inventory purchase rebates (“supplier rebates”) upon achievement of specified volume purchasing levels. Supplier rebates are accrued as part of cost of goods sold based on progress towards earning the supplier rebates, taking into consideration cumulative purchases of inventory to date and projected purchases through the end of the year. The Company estimates the rebates applicable to inventory on-hand at each period end based on the estimated percentage of supplier rebates to be earned. The Company also receives consideration from suppliers to promote their products (“marketing and advertising allowances”), which are accrued as part of cost of goods sold or selling, general and administrative expenses, depending on the nature of the allowance. Total rebates and marketing and advertising allowances receivable at December 31, 2018 and 2017 were $18.0 million and $23.3 million, respectively, included in prepaid expenses and other current assets.

Revenue recognition

Revenue recognition

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in Accounting Standards Update 2014-09, Revenue from Contracts with Customers, as amended (“Topic 606”). The Company’s building products contracts typically contain a promise to supply multiple distinct products and thus, they generally contain multiple performance obligations under Topic 606. Depending on the nature of the promises within the Company’s construction services contracts and whether they are distinct under Topic 606, there may be a single performance obligation or multiple performance obligations. For contracts with multiple performance obligations, the contract’s transaction price is allocated to each distinct performance obligation based on the standalone selling price of each distinct good or service, which is generally determined based on the prices charged to customers.

The Company recognizes revenue for its building products contracts when control of the promised goods (the performance obligations) is transferred to the Company’s customers. This generally occurs at a point in time when the products are delivered and the customer obtains physical possession, legal title and the risks and rewards of ownership. However, for certain product offerings, products are customized to customer specifications and the customer benefits from the Company’s performance over time as deliveries are made. As such, the Company has determined that an output method based on units delivered best depicts the transfer of control to the customer.

The Company generally recognizes revenue for its construction services contracts over time using cost based input methods. Periodic estimates of progress towards completion are made based on either a comparison of labor costs incurred to date with total estimated contract labor costs or total costs incurred to date with total estimated contract costs. Incurred costs represent work performed, which correspond and best depict transfer of control to the customer.

Contract revenues and contract costs to be recognized are dependent on the accuracy of estimates, including quantities of materials, labor productivity and other cost estimates. Historically, the Company has made reasonable estimates of the extent of progress towards completion and contract completion costs. Due to uncertainties inherent in the estimation process, it is possible that actual completion costs may vary from estimates. Revenue recognized for performance obligations satisfied over time for the year ended December 31, 2018 represented approximately 26% of total revenues.

Estimated losses on uncompleted contracts and changes in contract estimates reflect the Company’s best estimate of probable losses of unbilled receivables, and are recognized in the period such revisions are known and can be reasonably estimated. These estimates are recognized in cost of sales. Estimated losses on uncompleted contracts and changes in contract estimates are established by assessing estimated costs to complete, change orders and claims for uncompleted contracts. Assumptions for estimated costs to complete include material prices, labor costs, labor productivity and contract claims. Such estimates are inherently uncertain and it is possible that actual completion costs may vary from these estimates.

All sales recognized are net of allowances for discounts and estimated returns, based on historical experience. Taxes assessed by governmental authorities that are directly imposed on the Company’s revenue-producing transactions are excluded from sales. The Company accounts for shipping and handling costs associated with its contracts as a fulfillment cost and expenses these as incurred within selling, general and administrative expenses.

Contract balances

Contract balances

The timing of revenue recognition, invoicing and cash collection affects receivables, contract assets and contract liabilities on the Company’s consolidated balance sheets. For building products contracts that contain performance obligations satisfied at a point in time, the Company recognizes revenue upon satisfaction of the performance obligation and then bills the customer, resulting in a receivable. For building products contracts that contain performance obligations satisfied over time, the Company recognizes revenue as the performance obligation is satisfied, but prior to billing, resulting in an unbilled receivable, as the Company has an unconditional right to payment.

For the Company’s construction services contracts, amounts are generally billed as work progresses in accordance with agreed-upon contractual terms. Revenue is also recognized over time as the performance obligations are satisfied, which can result in contract assets and liabilities, on a contract-by-contract basis, due to timing differences between billing and revenue recognition. Contract assets include unbilled amounts when the revenue recognized exceeds the amount billed to the customer. Conversely, contract liabilities include amounts that have been billed to the customer in excess of the revenue recognized.

At times, the Company will have a right to payment from previous performance that is conditional on something other than passage of time, such as retainage, which creates a contract asset. Conversely, the Company may receive advances from customers prior to the Company’s performance, which creates a contract liability.

Contract assets are reclassified to a receivable when the right to consideration becomes unconditional. The Company’s terms generally provide for payment within 30 days of being invoiced. On occasion, when necessary to compete in certain circumstances, the Company will offer extended payment terms, which do not exceed one year.

Shipping and handling costs

Shipping and handling costs

The Company includes shipping and handling costs in selling, general and administrative expenses and depreciation expense on the consolidated statements of operations. Shipping and handling costs included in selling, general and administrative expenses were $189.6 million, $172.2 million and $152.7 million for the years ended December 31, 2018, 2017 and 2016, respectively.

Property and equipment

Property and equipment

Property and equipment are stated at cost. Expenditures for renewals and betterments, which extend the useful lives of assets, are capitalized while maintenance and repairs are charged to expense as incurred. Property and equipment obtained through acquisition are stated at estimated fair market value as of the acquisition date, and are depreciated over their estimated remaining useful lives, which may differ from the Company’s stated policies for certain assets. Gains and losses related to the sale of property and equipment are recorded as selling, general and administrative expenses.

Property and equipment are depreciated using the straight-line method and are generally depreciated over the following estimated service lives:

Buildings and improvements	3–30 years
Leasehold improvements	Lesser of life of the asset or remaining
	lease term, and not to exceed 15 years
Furniture, fixtures and equipment	2–10 years
Vehicles	4–10 years

Property and equipment that is expected to be sold within the next twelve months, is actively marketed in its current condition for a price that is reasonable in comparison to its estimated fair value and meets other relevant held-for-sale criteria are classified as assets held for sale. Assets held for sale are measured at the lower of carrying amount or fair value less costs to sell and are no longer depreciated. An impairment for assets held for sale is recognized if the carrying amount is not recoverable. Assets held for sale were not presented separately and were classified as other long-term assets in the consolidated balance sheets and were $1.3 million and $2.3 million at December 31, 2018 and 2017, respectively.

Goodwill and other intangible assets

Goodwill and other intangible assets

At least annually, or more frequently as changes in circumstances indicate, the Company tests goodwill for impairment. To the extent that the carrying value of the net assets of any of the reporting units having goodwill is greater than their estimated fair value, the Company may be required to record impairment charges. The Company’s five operating segments, which have been determined to be the Company’s reporting units, are the Mid-Atlantic, Southeast, Texas, Intermountain and Western divisions. The chief operating decision maker (“CODM”) reviews aggregate information to allocate resources and assess performance. Based on the CODM’s review, as well as the similar economic characteristics, nature of products, distribution methods and customers of the divisions, the Company has aggregated its operating segments into one reportable segment. The Company is required to make certain assumptions and estimates regarding the fair value of the reporting units containing goodwill when assessing for impairment. Changes in the fact patterns underlying such assumptions and estimates could ultimately result in the recognition of additional impairment losses.

The Company completes its annual impairment assessment during the third quarter of each year. The Company did not recognize any impairment for the years ended December 31, 2018, 2017 and 2016. The Company may consider qualitative factors as part of its annual impairment assessment to determine whether it is more likely than not that a reporting unit’s carrying value exceeds its fair value. If the Company’s qualitative assessment indicates that goodwill impairment is more likely than not, the Company performs the two-step impairment test. Alternatively, the Company may bypass the qualitative test and initiate goodwill impairment testing with the first step of the two-step goodwill impairment test. During the first step of the goodwill impairment test, the fair value of the reporting unit is compared to its carrying value, including goodwill. The Company may derive a reporting unit’s fair value through a combination of the market approach (a guideline transaction method) and the income approach. The income approach uses a reporting unit’s projection of estimated future cash flows that is discounted at a market derived weighted average cost of capital. The projection uses management’s best estimates of economic and market conditions over the projected period including growth rates in sales, costs, estimates of future expected changes in operating margins and cash expenditures.

If the fair value of a reporting unit exceeds its carrying value, then the Company concludes no goodwill impairment has occurred. If the carrying value of the reporting unit exceeds its fair value, the Company performs the second step of the goodwill impairment test to measure possible goodwill impairment loss. During the second step, the implied fair value of the reporting unit’s goodwill is compared to the carrying value of its goodwill. If the carrying value of the reporting unit’s goodwill exceeds the implied fair value of the goodwill, the Company would recognize an impairment loss in an amount equal to the excess, not to exceed the carrying value of the reporting unit’s goodwill.

Acquired intangible assets other than goodwill are amortized over their weighted average amortization period unless they are determined to be indefinite. Acquired intangible assets are carried at cost, less accumulated amortization. For intangible assets purchased in a business combination, the estimated fair values of the assets received are used to establish the carrying value. The fair value of acquired intangible assets is determined using common valuation techniques, and the Company employs assumptions developed using the perspective of a market participant.

Impairment of long-lived assets

Impairment of long-lived assets

Long-lived assets, such as property, equipment and purchased intangible assets subject to amortization, are reviewed for impairment whenever facts and circumstances indicate that the carrying amount of an asset may not be recoverable. For impairment testing of long-lived assets, the Company identifies asset groups at the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the assets. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the estimated fair value of the asset.

Treasury stock

Treasury stock

During the year ended December 31, 2018, the Company’s board of directors authorized a $75.0 million share repurchase program. Repurchases may be made at management’s discretion from time to time on the open market, subject to applicable laws, or through privately negotiated transactions. The repurchase program will expire on November 20, 2019 or may be suspended or discontinued at any time. During the year ended December 31, 2018, utilizing cash from operations, the Company repurchased 0.2 million shares at a weighted average price of $15.91 per share for a total cost of $2.9 million. These repurchased shares are available for future issuance and are reflected as treasury stock, at cost, on the consolidated balance sheet as of December 31, 2018. As of December 31, 2018, the Company had approximately $72.1 million of capacity remaining under the current share repurchase authorization. Subsequent to December 31, 2018, the Company repurchased 0.7 million shares at a weighted average price of $16.82 per share for a total cost of $11.5 million.

Employees have the option to surrender shares to the Company to satisfy their tax withholding obligations in connection with the vesting of restricted stock and restricted stock unit awards. These surrendered shares are reflected as treasury stock, at cost, on the consolidated balance sheet as of December 31, 2018 and 2017.

Merger and integration costs

Merger and integration costs

Merger and integration costs related to the ongoing integration of Building Materials Holding Corporation (“BMHC”) and Stock Building Supply Holdings, Inc. (“SBS”), as a result of the 2015 merger transaction, consist primarily of severance, rebranding, system integration costs and professional fees.

Income taxes

Income taxes

The Company accounts for income taxes in accordance with ASC 740, Income Taxes (“ASC 740”), which requires an asset and liability approach for measuring deferred taxes based on temporary differences between the financial statement and tax basis of assets and liabilities existing at each balance sheet date using enacted tax rates for years in which taxes are expected to be paid or recovered.

The Company evaluates its deferred tax assets on a quarterly basis to determine whether a valuation allowance is required. In accordance with ASC 740, the Company assesses whether a valuation allowance should be established based on its determination of whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets depends primarily on: (i) the Company’s ability to carry back net operating losses to tax years where it has previously paid income taxes based on applicable federal law; (ii) the timing of the reversal of deferred tax liabilities and (iii) the Company’s ability to generate future taxable income during the periods in which the related deferred tax assets are deductible. The assessment of a valuation allowance includes giving appropriate consideration to all positive and negative evidence related to the realization of the deferred tax asset. This assessment considers, among other things, the nature, frequency and severity of current and cumulative losses, forecasts of future profitability, the duration of statutory carryforward periods, the Company’s experience with operating loss and tax credit carryforwards not expiring unused and tax planning alternatives. Significant judgment is required in determining the future tax consequences of events that have been recognized in the Company’s consolidated financial statements and/or tax returns. Actual outcomes of these future tax consequences could differ materially from the outcomes that the Company currently anticipates.

ASC 740 defines the methodology for recognizing the benefits of uncertain tax return positions as well as guidance regarding the measurement of the resulting tax benefits. These provisions require an enterprise to recognize the financial statement effects of a tax position when it is more likely than not, which is defined as a likelihood of more than 50%, based on technical merits, that the position will be sustained upon examination. The evaluation of whether a tax position meets the more likely than not recognition threshold requires a substantial degree of judgment by management based on the individual facts and circumstances. Actual results could differ from estimates. The Company had no material uncertain tax positions as of December 31, 2018.

The Company’s policy is to recognize interest and penalties related to income tax liabilities and unrecognized tax benefits in income tax expense.

Casualty and health insurance

Casualty and health insurance

The Company carries insurance for general liability, auto liability and workers’ compensation exposures subject to deductibles or self-insured retentions it believes to be reasonable under the circumstances, and the Company self-insures for employee and eligible dependent health care claims, with insurance purchased from independent carriers to cover individual claims in excess of the self-insured limits. The expected liability for unpaid claims, including incurred but not reported losses, is reflected on the consolidated balance sheets as a liability with current and long-term components. The amount recoverable from insurance providers is reflected on the consolidated balance sheets in prepaid expenses and other current assets. Provisions for losses are developed from actuarial valuations that rely upon the Company’s past claims experience, which considers both the frequency and settlement of claims. The casualty and health insurance liabilities are recorded at their undiscounted value.

In January 2015, the Company entered into a retroactive reinsurance contract to transfer the risk of loss of certain insurance reserves for workers’ compensation claims incurred from 2006 to 2011 to a reinsurer. Pursuant to the reinsurance contract, the reinsurer is obligated to pay an aggregate maximum of $17.5 million for these claims with any excess borne by the Company. The Company maintains the insurance reserves related to these claims as a liability on its consolidated balance sheet with an offsetting reinsurance receivable, which includes current and long-term components. As of December 31, 2018 and 2017, the carrying value of the insurance reserves related to these claims and the offsetting reinsurance receivable was $3.7 million and $4.5 million, respectively. Changes in these claims are recorded as an increase or decrease in the insurance reserves and corresponding increase or decrease in the reinsurance receivable. Additionally, the Company monitors the financial condition of the reinsurer to minimize its exposure to significant losses from reinsurer insolvency.

Retirement savings program

Retirement savings program

The Company sponsors a defined contribution retirement savings plan. The Company has recorded expense of $5.9 million, $5.2 million and $4.6 million related to employer contributions for the years ended December 31, 2018, 2017 and 2016, respectively. These expenses are recorded to either selling, general and administrative expenses or cost of sales on the consolidated statements of operations, depending on the classification of the employee.

Lease obligations

Lease obligations

The Company recognizes lease obligations with fixed escalations of rental payments on a straight-line basis over the lease term, with the amount of rental expense in excess of lease payments recorded as a deferred rent liability. Lease incentives received are also recorded as a deferred rent liability and are amortized as reductions to rent expense over the lease term. As of December 31, 2018 and 2017, the Company had a deferred rent liability of $5.0 million and $4.2 million, respectively, included in accrued expenses and other liabilities and other long-term liabilities on the consolidated balance sheets.

Advertising and promotion

Advertising and promotion

Costs associated with advertising and promoting products and services are expensed in the period incurred. Cooperative advertising allowances that are reimbursement of specific, incremental and identifiable costs incurred to promote vendors’ products are recorded as an offset against advertising expenses in selling, general and administrative expenses. If those conditions are not met, the cooperative advertising allowances are recorded as a reduction in inventory and a subsequent reduction in cost of goods sold when the related product is sold. For the years ended December 31, 2018, 2017 and 2016, the Company recorded $4.9 million, $5.8 million and $3.7 million, respectively, of advertising and promotion expenses, net of cooperative advertising allowances, in selling, general and administrative expenses.

Stock-based compensation

Stock-based compensation

In accordance with the requirements of ASC 718, Compensation—Stock Compensation(“ASC 718”), the Company measures and recognizes compensation expense for all share-based payment awards made to employees using a fair value based pricing model. The compensation expense is recognized over the requisite service period, using graded vesting.

Debt issuance costs

Debt issuance costs

Costs incurred in connection with the Company’s revolving line of credit and senior secured notes are capitalized and amortized over the term of the applicable agreement. Total debt issuance costs, net of accumulated amortization, were $6.4 million and $8.1 million as of December 31, 2018 and 2017, respectively. Debt issuance costs related to the Company’s revolving line of credit and senior secured notes are included in other long-term assets and long-term debt, respectively, on the consolidated balance sheets. Amortization of debt issuance costs for the years ended December 31, 2018, 2017 and 2016 was $1.7 million, $1.7 million and $3.1 million, respectively, and is included in interest expense on the consolidated statements of operations.

Derivatives

Derivatives

The Company will occasionally enter into derivative instruments to offset existing or expected risks associated with fluctuations in commodity prices. The Company does not enter into derivative instruments for speculative or trading purposes. The Company recognizes all derivative instruments as assets or liabilities in the Company’s balance sheets at fair value. Changes in the fair value of derivative instruments that are not designated as hedges or that do not meet the hedge accounting criteria are reported in earnings. The Company elected not to designate any new derivative instruments as hedges for the years ended December 31, 2018, 2017 or 2016, and therefore, all changes in the fair market value of the derivative instruments have been reported in cost of goods sold on the consolidated statements of operations.

Warranty expense

Warranty expense

The Company has warranty obligations with respect to most manufactured products. As of December 31, 2018 and 2017, the Company had warranty liabilities of $2.9 million and $2.5 million, respectively, included in accrued expenses and other liabilities on the consolidated balance sheets.

Comprehensive income

Comprehensive income

Comprehensive income is equal to the net income for all periods presented.

Statement of cash flows

Statement of cash flows

Proceeds from revolving line of credit and Repayments of proceeds from revolving line of credit as presented on the Consolidated Statements of Cash Flows includes all cash activities and transactions between the Company and its associated lenders in relation to the revolving line of credit, excluding interest and fees, and is specifically inclusive of operating cash receipts which are automatically applied to the revolving line of credit pursuant to a cash sweep agreement. See Note 9 for further details on the Company’s revolving line of credit.

Recently issued accounting pronouncements

Recently adopted accounting pronouncements

In May 2014, the FASB issued Topic 606. Topic 606 provides a comprehensive revenue recognition model requiring companies to recognize revenue for the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. The guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. The Company adopted Topic 606 on January 1, 2018 using the modified retrospective transition method. See Note 11 for further details.

In August 2016, the FASB issued Accounting Standards Update 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). ASU 2016-15 was issued to decrease the diversity in practice of how certain cash receipts and cash payments are presented and classified in the statement of cash flows by providing guidance on eight specific cash flow issues. Retrospective application is required. ASU 2016-15 became effective for the Company’s annual and interim periods beginning on January 1, 2018. The adoption of the standard did not have a material impact on the Company’s consolidated financial statements.

In November 2016, the FASB issued Accounting Standards Update 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (“ASU 2016-18”). ASU 2016-18 requires that the statement of cash flows include restricted cash in the beginning and end-of-period total amounts shown and that the statement of cash flows explain the changes in restricted cash during the period. Retrospective application is required. ASU 2016-18 became effective for the Company’s annual and interim periods beginning on January 1, 2018. The adoption of the standard did not have a material impact on the Company’s consolidated financial statements.

In January 2017, the FASB issued Accounting Standards Update 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business (“ASU 2017-01”). ASU 2017-01 provides guidance in determining when a set of assets and activities meets the definition of a business. Prospective application is required. ASU 2017-01 became effective for the Company’s annual and interim periods beginning on January 1, 2018. The adoption of the standard did not have a material impact on the Company’s consolidated financial statements.

In February 2017, the FASB issued Accounting Standards Update 2017-05, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets (“ASU 2017-05”). ASU 2017-05 clarifies the scope of Subtopic 610-20, which provides guidance for recognizing gains and losses from the sale or transfer of nonfinancial assets in contracts with noncustomers. ASU 2017-05 also provides guidance for partial sales of nonfinancial assets. ASU 2017-05 became effective for the Company’s annual and interim periods beginning on January 1, 2018. The adoption of the standard did not have a material impact on the Company’s consolidated financial statements.

In May 2017, the FASB issued Accounting Standards Update 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting (“ASU 2017-09”). ASU 2017-09 provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting under ASC 718. ASU 2017-09 is to be applied prospectively to an award modified on or after the adoption date. ASU 2017-09 became effective for the Company’s annual and interim periods beginning on January 1, 2018. The adoption of the standard did not have a material impact on the Company’s consolidated financial statements.

In March 2018, the FASB issued Accounting Standards Update 2018-05, Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118 (“ASU 2018-05”). ASU 2018-05 adds paragraphs to the ASC pursuant to SEC Staff Accounting Bulletin No. 118, which addresses the application of U.S. GAAP in situations when a company does not have the necessary information available, prepared or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Cuts and Jobs Act (the “2017 Tax Act”). ASU 2018-05 provides entities with a one year measurement period from the December 22, 2017 enactment date in order to complete the accounting. The Company recognized a provisional net tax benefit of $3.6 million related to the impact of the 2017 Tax Act during the year ended December 31, 2017. In the fourth quarter of 2018, the Company completed its accounting for the income tax effects of the 2017 Tax Act within the measurement period as provided under ASU 2018-05, which resulted in recognizing an additional tax benefit of $0.5 million for the year ended December 31, 2018.

Recently issued accounting pronouncements not yet adopted

In February 2016, the FASB issued Accounting Standards Update 2016-02, Leases, and issued subsequent amendments to the initial guidance to provide additional clarification on specific topics (“ASU 2016-02”). ASU 2016-02 establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the statement of operations. The Company plans to adopt the standard on January 1, 2019, utilizing the transition option provided by Accounting Standards Update 2018-11, Leases (Topic 842): Targeted Improvements, which the FASB issued in July 2018 and allows the Company to apply the guidance in ASU 2016-02 as of the adoption date, while applying the legacy guidance in ASC 840, Leases, including its disclosure requirements, in the comparative periods. As a lessee, certain of the Company’s leases under existing guidance are classified as operating leases that are not recorded on the balance sheet but are recorded in the statement of operations as expense is incurred. Upon adoption of the standard, the Company will be required to record substantially all leases on the balance sheet as a ROU asset and a lease liability. The Company expects to utilize the package of practical expedients permitted by the transition guidance in ASU 2016-02, which allows the Company to carry forward its identification of contracts that are or contain leases, its historical lease classification and its initial direct costs for existing leases. The Company currently expects to recognize lease liabilities for its operating leases totaling between $110.0 million and $125.0 million upon adoption, of which between $22.0 million and $37.0 million will be classified as a current liability. The initial ROU assets recognized will be equal to the initial operating lease liabilities, adjusted for the balance on adoption date of prepaid and accrued rent, lease incentives, unamortized initial direct costs and unamortized assets and liabilities related to favorable and unfavorable lease terms. The Company currently expects to recognize ROU assets totaling between $105.0 million and $120.0 million upon adoption. The Company does not expect adoption of the standard to have a material impact on the Company’s historical capital leases, which will be presented as finance leases under ASU 2016-02. See Note 13 for further information on the Company’s leases.

In June 2016, the FASB issued Accounting Standards Update 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 amends the impairment model by requiring entities to use a forward-looking approach based on expected losses to estimate credit losses on certain types of financial instruments, including trade receivables. ASU 2016-13 is effective for the Company’s annual and interim periods beginning on January 1, 2020, with early adoption permitted beginning January 1, 2019. Modified retrospective application is required, with certain exceptions. The Company expects to adopt the standard on January 1, 2020 and continues to evaluate the impact of the standard on its consolidated financial statements.

In January 2017, the FASB issued Accounting Standards Update 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). ASU 2017-04 simplifies the accounting for goodwill impairment by removing Step 2 of the goodwill impairment test, which requires computation of the implied fair value of a reporting unit’s goodwill. The amount of a goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. ASU 2017-04 is effective for the Company’s annual goodwill impairment test and any interim tests during the Company’s annual and interim periods beginning on January 1, 2020. Early adoption is permitted for goodwill impairment tests performed on testing dates after January 1, 2017. Prospective application is required. The adoption of the standard is not expected to have a material impact on the Company’s consolidated financial statements.

In August 2018, the FASB issued Accounting Standards Update 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, and issued subsequent amendments to the initial guidance to provide additional clarification on specific topics (“ASU 2018-13”). ASU 2018-13 modifies the disclosure requirements on fair value measurements by removing, modifying and adding certain disclosure requirements in ASC 820. ASU 2018-13 is effective for the Company’s annual and interim periods beginning on January 1, 2020, with early adoption permitted. Certain disclosures in ASU 2018-13 are required to be applied prospectively, while others require retrospective application. The Company is evaluating the impact of the standard on its consolidated financial statements.

Acquisitions

Acquisitions and Disposition

For all acquisitions, the Company allocates the purchase price to assets acquired and liabilities assumed as of the date of acquisition based on the estimated fair values at the date of acquisition. The excess of the fair value of the purchase consideration over the fair values of the identifiable assets and liabilities is recorded as goodwill. Management makes significant estimates and assumptions when determining the fair value of assets acquired and liabilities assumed. These estimates include, but are not limited to, discount rates, projected future net sales, projected future expected cash flows and useful lives.

The Company accounts for all acquisitions using the acquisition method of accounting under ASC 805, Business Combinations (“ASC 805”), whereby the results of operations of the acquired company are included in the Company’s consolidated financial statements beginning on the acquisition date.

Inventories

Inventories consist principally of materials purchased for resale, including lumber, sheet goods, millwork, doors and windows, as well as certain manufactured products and are valued at the lower of cost or net realizable value, with cost being measured using a weighted average cost approach, which approximates the first-in, first-out approach.

Earnings Per Share [Abstract]

Earnings per share

Earnings Per Share

Basic net income per share (“EPS”) is calculated by dividing net income attributable to common stockholders by the weighted average shares outstanding during the period. Diluted EPS is calculated by adjusting weighted average shares outstanding for the dilutive effect of potential common shares, determined using the treasury-stock method. For purposes of the diluted EPS calculation, stock options, restricted stock and restricted stock unit awards are considered to be potential common shares. Performance-based restricted stock units are not included in the calculation of diluted EPS until they are contingently issuable.
