Acquisition of Farner-Bocken Company
On July 10, 2017, the Company completed the acquisition of substantially all of the assets of Farner-Bocken Company (“Farner-Bocken”), a regional convenience wholesaler headquartered in Carroll, Iowa. The acquisition increased the Company’s market presence primarily in the Midwestern U.S. and will further enhance the Company’s ability to cost effectively service national and regional retailers. The acquisition was accounted for as a business combination in accordance with ASC 805 - Business Combinations. The total purchase consideration was $174.0 million of which $169.0 million was paid at closing. The remaining $5.0 million indemnity holdback was released in annual installments over two years from the date of the agreement, less amounts related to indemnification claims made pursuant to the purchase agreement, if any. In July 2018 and 2019, the Company released $2.5 million, respectively, as annual installments of the indemnity holdback. The acquisition was funded through borrowings under the Company’s revolving credit facility.
The fair values of the assets acquired and liabilities assumed were determined using the income, cost and market approaches, all Level 3 measurements under the fair value hierarchy. The income approach was primarily used to value the intangible assets, consisting primarily of acquired customer relationships and trade names. The income approach estimates fair value for an asset based on the present value of cash flows projected to be generated by the asset. Projected cash flows are discounted at a required rate of return that reflects the relative risk of achieving the cash flows and the time value of money. The cost approach, which estimates value by determining the current cost of replacing an asset with another of equivalent economic utility, was used primarily for property and equipment. The cost to replace a given asset reflects the estimated reproduction or replacement cost for the property, less an allowance for loss in value due to depreciation.
The Company determined the fair values of tangible fixed assets and intangible assets acquired with the assistance of independent valuation consultants. Goodwill is calculated as the difference between the acquisition date fair value of the total purchase consideration and the fair value of the net assets acquired, and represents the future economic benefits that the Company expects to achieve as a result of the acquisition. The following table presents the assets acquired and liabilities assumed, based on their fair values and purchase consideration as of the acquisition date (in millions):

Unless the context indicates otherwise, all references in this Annual Report on Form 10-K to “Core-Mark,” “the Company,” “we,” “us,” or “our” refer to Core-Mark Holding Company, Inc. and its subsidiaries.

Company Overview
Core-Mark is one of the largest wholesale distributors to the convenience retail industry in North America, providing sales, marketing, technology, distribution and logistics services to approximately 40,000 customer locations across the United States (“U.S.”) and Canada through 32 distribution centers (excluding two distribution facilities we operate as a third-party logistics provider). Our origins date back to 1888, when Glaser Bros., a family-owned-and-operated candy and tobacco distribution business, was founded in San Francisco, California.
Our mission is to be the most valued marketer of fresh, food and broad-line supply solutions to the convenience retail industry. Consistent with this mission, our strategic framework is centered around three key initiatives: growing sales and margins faster than the industry, providing industry-leading category management solutions and leveraging our cost structure.
We operate in an industry where, in 2019, total in-store sales at convenience retail locations across both the U.S. and Canada were approximately $293.5 billion. In the U.S., total in-store sales at convenience locations in 2019 were approximately $251.9 billion, an increase of 4.0% over the prior year, based on the National Association of Convenience Stores (“NACS”) State of the Industry (“SOI”) report. Over the ten years from 2010 through the end of 2019, U.S. convenience in-store sales have increased by a compounded annual growth rate of approximately 2.8%. The most recent NACS Convenience Industry Store Count noted that the U.S. had approximately 153,000 convenience store locations as of December 31, 2019. Approximately 100,000, or 65%, of the convenience stores in the U.S. are considered independents with ten or fewer stores. In Canada, we estimate that total in-store sales at convenience locations in 2019 were approximately CAD $55.2 billion generated through approximately 25,000 stores, based on the Convenience Industry Council of Canada 2020 SOI report.
Core-Mark is one of two national distributors to the convenience store industry in the U.S. and is the largest distributor in Canada. Our established national market presence rests primarily with our ability to service customers in every geographic region within the U.S. through 27 distribution centers and to service customers in Canada through our five Canadian distribution centers. We offer a wide array of products, marketing programs and services that leverage our scale to assist our customers in growing their business. Our leading category management strategies including our Vendor Consolidation Initiative (“VCI”), Focused Marketing Initiative (“FMI”) and “Fresh” products and food service programs have a proven track record of helping our customers grow their sales and profits at an accelerated rate. We believe this gives us a strong competitive advantage in the North American convenience retail industry.
Company Highlights
In 2020, our operating results were impacted by the effects of the novel coronavirus pandemic (“COVID-19”). We experienced a significant shift in our sales mix as a result of changes in consumer buying habits related to the COVID-19 pandemic and, in response, implemented cost savings initiatives which allowed us to achieve the following significant accomplishments:
Record net sales of $16.96 billion.
Our net income increased 9.5% to $63.2 million.
Adjusted EBITDA increased 6.0% to $202.2 million.
Although we are seeing signs of recovery as consumer purchase trends improve, we expect future results to continue to be impacted by the effects of the COVID-19 pandemic.
Our growth the past several years has been driven primarily by our business strategies described more fully below. We believe these strategies have positioned us to continue to grow our approximate 7% market share of North American convenience store merchandise sales, and to take advantage of growth opportunities through acquisition and with other retail store formats.

1


Business Strategy Overview
Our overarching strategic mission is to increase shareholder return by growing faster and more profitably than our industry, being the industry leader in category management solutions and leveraging operating costs to increase profitability. We accomplish these strategic priorities through numerous vehicles designed to differentiate Core-Mark from its competition and bring value to convenience retail formats across our North American distribution area. Some key success drivers in this pursuit are:
Fresh Products and Food Service. There is an increasing trend among consumers to purchase fresh food and food service products from convenience and other retail store formats. To meet this demand, we have modified and upgraded our refrigerated capacity, including investing in chill docks, and tri-temperature (“tri-temp”) trailers, which provide the infrastructure to deliver a significant range of chilled items including milk, produce, fresh and food service items to retail outlets. We have established partnerships with leading national commissaries, strategically-located dairies, fresh kitchens, food service providers and bakeries to further enable us to deliver premium consumer items such as fresh pizza, fried chicken, fresh made sandwiches, wraps, cut-fruit, parfaits, pastries, doughnuts, bread and home meal replacement solutions. We continue to promote our fresh products through the development of unique and comprehensive marketing and equipment programs that assist retailers in showcasing their fresh product offerings. We believe our investments in infrastructure, combined with our strategically located suppliers and in-house expertise, positions us as a leader in providing fresh food and food service products and programs to the convenience retail industry. Fresh items are increasingly driving consumer decisions and will continue to be an important category.
Vendor Consolidation Initiative. We expect our VCI program will allow us to continue to grow our sales by capitalizing on the highly fragmented supply chain that services the convenience retail industry. A convenience retailer generally receives store merchandise through a large number of direct-store deliveries. This represents a highly inefficient and costly process for retailers. Our VCI program targets inefficiencies in the convenience store supply chain by offering the retailer the ability to receive multiple weekly deliveries for their products, including dairy and other merchandise they previously purchased from multiple direct-store delivery companies. This simplifies the customer supply chain and provides retailers with an opportunity to improve inventory turns and working capital, reduce operational and transaction costs, and greatly diminish their out-of-stocks.
Focused Marketing Initiative. Designed to enhance our relationship with our independent customer base and to further differentiate us in the market place, our FMI program is centered on increasing the sales and profitability of the independent store through improved category insights, optimized retail price strategy and demographic decision-making, along with providing Core-Mark’s marketing solutions to create a comprehensive retail marketing strategy. We believe our innovative approach, which focuses on building a trusted partnership with our customers, has established us as the market leader in providing valuable marketing and supply chain solutions to the convenience retail industry.
Center of Excellence (“COE”). During the first quarter of 2020, we opened the COE at our Westlake, Texas campus. The COE is a dynamic collaboration space for leaders in the convenience retail channel designed to inspire, educate and challenge visitors to think big in growing their sales and profits. Within the 14,000 sq. ft. space, we have created an environment that combines forward-looking consumer trends with real time data, which will allow us to align with our customers and define the future of convenience. The COE is physically designed with five unique hubs – Insights and Data Center, Collaboration Hub, Store Innovation, Culinary Test Kitchen and People Training Facility – to deliver an immersive experience for convenience retailers and strategic vendors.
Technology & Digital Solutions. We are committed to providing tangible value to our retail partners, and in doing so will create a level of differentiation from our competition. We have recently formed exclusive strategic partnerships that will bring operational and business-to-consumer technology solutions to our retailers, that will help them grow their sales, increase market share, meet consumer expectations and more effectively manage their business. These solutions include a two-tiered loyalty platform, enabling retailers to better connect and engage with their consumers to drive behavior in a meaningful way. Additionally, we offer scan data aggregation software and back-office solutions that will help retailers better manage their business and also capitalize on consumer packaged goods strategies for their benefit. And lastly, we can provide a frictionless checkout and payment solution, designed to enhance the experience of the consumers, while, over time, reducing demands on labor. As technologies advance, we are committed to providing relevant and compelling solutions, in our pursuit to be the leader in category management.
Acquisitions and Expansion. We believe there remains a significant opportunity to increase our market presence and revenue growth through strategic and opportunistic acquisitions and the continued expansion of our facility infrastructure. We completed five acquisitions and added four primary distribution centers between 2011 and 2020, which expanded our distribution network, product selection and customer base. We will continue to be opportunistic in pursuing acquisitions that
2


allow further leveraging of our geographic footprint and bring Fresh Products, Food Service and our other category management solutions to a broader customer base.
Business Transformation. As a contributor to cost leverage, we have embarked on a multiyear transformation and efficiency process. Starting with the implementation of SAP in 2016, we sought to bring a technology solution that would help build a more efficient infrastructure for our finance organization. Leveraging this tool, we have consolidated numerous transactional activities such as accounts payable and payment processing along with enhancing value in our overall accounting function. In addition to our finance transformation, we have completed a significant sales transformation focused on driving growth and compensation alignment. From the operations and transportation front, we continue to add technologies, such as Omni-Trac One, pick-to-voice, and robotic tote sortation and stacking, and continue to look for other leverage and efficiency opportunities to provide further cost leverage.
Competitive Strengths
We believe we have the following fundamental competitive strengths, which form the foundation for our business strategy:
Innovation and Flexibility. Wholesale distributors typically provide convenience retailers access to a broad product line, the ability to place small quantity orders, inventory management and access to trade credit. Our capability to increase sales and profitability with existing and new customers is based on our ability to deliver consistently high levels of service, innovative category management and marketing programs, technology solutions and logistics support. We believe we are the best in class at capitalizing on emerging trends and bringing retailers our unique category management solutions such as fresh foods, food service solutions and healthier options, as well as our VCI and FMI initiatives.
Distribution Capabilities. The wholesale distribution industry is highly fragmented and historically has consisted of a large number of small, privately-owned businesses and a small number of large, full-service wholesale distributors serving multiple geographic regions. Relative to smaller competitors, large national distributors such as Core-Mark benefit from several competitive advantages including: increased purchasing power, the ability to service large national chain accounts, economies of scale in sales and operations, and the resources to invest in information technology and other productivity-enhancing technologies. Our wholesale distributing capabilities provide valuable services to both manufacturers of consumer products and convenience retailers. Manufacturers benefit from our broad retail coverage, inventory management, efficiency in processing small orders and frequency of deliveries. Convenience retailers benefit from our distribution capabilities by gaining access to a broad product line, availability of multi-time per week delivery through the elimination of unnecessary vendors and speed of delivery, and optimizing inventory management.
Customers
We service approximately 40,000 customer locations in all 50 states in the U.S., five Canadian provinces and two Canadian territories. Our traditional convenience store customers include many of the national and super-regional convenience store operators, as well as independently owned convenience stores. Our alternative outlet customers comprise a variety of store formats, including grocery stores, drug stores, mass merchants, liquor stores, cigarette and tobacco shops, hotel gift shops, military exchanges, college and corporate campuses, casinos, airport concessions and other specialty and small format stores that carry convenience products.
Our top ten customers accounted for approximately 41% of our net sales in 2020 including Murphy U.S.A., our largest customer, which accounted for 13.9% of our total net sales.
Products
We purchase a variety of brand name and private label products, representing approximately 61,000 stock keeping units (“SKUs”), from suppliers and manufacturers. Cigarette products represent less than 4% of our total SKUs purchased. We offer customers a variety of food/non-food products, including, candy, snacks, groceries, food, fresh products, dairy, bread, beverages, other tobacco products, alternative nicotine products, general merchandise, and health and beauty care products.

Cigarette Products. We purchase cigarette products from major U.S. and Canadian manufacturers. We have no long-term cigarette purchase agreements and buy substantially all of our products on an as-needed basis. Cigarette manufacturers historically offer structured incentive programs to wholesalers based on maintaining market share and executing promotional programs. Net sales of the cigarettes category increased 3.8% in 2020 to $11,310.5 million, accounting for approximately 66.7% of our total net sales and 25.2% of our total gross profit. We control major purchases of cigarettes centrally to optimize inventory levels and purchasing opportunities.
In 2020, our cigarette carton sales in the U.S. and Canada increased 0.2% and 0.7%, respectively. The increase in carton sales in the U.S. was driven primarily by an increase in sales to existing customers, partially offset by a net decrease in the number of stores serviced during the year. Cigarette carton sales to existing customers during 2020 outperformed the historical industry rate of decline arising primarily from changes in consumer buying behavior as a result of the novel coronavirus (“COVID-19”) pandemic.
In the industry overall, U.S. and Canadian cigarette consumption has steadily declined over the last decade. Based on data compiled from the U.S. Department of Agriculture - Economic Research Service and provided by the Tobacco Merchants Association (“TMA”), total cigarette consumption in the U.S. declined from 309 billion cigarettes in 2010 to 229 billion cigarettes in 2019, or a compounded annual decline of approximately 3.0%. Total cigarette consumption declined in Canada from 32 billion cigarettes in 2010 to 25 billion cigarettes in 2019, or a compounded annual decline of approximately 2.4% based on statistics provided by the TMA. Although it is difficult to predict future cigarette consumption trends given the current COVID-19 pandemic environment, longer term we expect overall cigarette consumption to return to historical levels of decline. We expect cigarette manufacturers will continue to raise prices for the foreseeable future as carton sales decline in order to maintain or enhance their overall profitability.
Excise taxes are levied on cigarettes and other tobacco products by the U.S. and Canadian federal governments and are also imposed by various states, localities and provinces. We collect state, local, and provincial excise taxes from our customers and remit these amounts to the appropriate authorities based on the credit terms, if applicable, extended by each jurisdiction. Net sales and cost of sales includes amounts related to state, local and provincial excise taxes which were $3.3 billion, $3.3 billion and $3.5 billion for 2020, 2019 and 2018, respectively.
Food/Non-food Products. Our food products include food, candy, snacks, groceries, beverages and fresh products such as sandwiches, juices, salads, produce, dairy and bread. Our non-food products include cigars, tobacco, alternative nicotine products, health and beauty care products, general merchandise and equipment. In 2020, we experienced a significant shift in our sales mix as a result of changes in consumer buying habits related to the COVID-19 pandemic. Net sales of the combined food/non-food product categories declined 2.3% in 2020 to $5,647.4 million, which was 33.3% of our total net sales. While the changes in consumer buying habits impacted most of our food/non-food products, the largest sales declines were in the food, HB&G and candy categories, partially offset by growth in OTP sales. In addition to the impact of the COVID-19 pandemic on consumer buying habits, our HB&G category was also impacted by a decline in sales of alternative nicotine products due to the enactment of regulations governing the sale of flavored products. Combined sales of our Food and Fresh categories decreased $164.1 million, or 7.3%, to $2,085.1 million and the HB&G category decreased $45.9 million or 5.4% in 2020. Total sales of OTP increased $119.7 million, or 8.3%.

Table of Contents
Our strategy is to continue to grow sales of food/non-food products through our category management solutions including Fresh and Food Service, VCI and FMI. In order to take advantage of the significantly higher margins earned by food/non-food products, two of our key business strategies, Fresh and VCI, focus primarily on the highest margin categories in the food/non-food group. Gross profit for food/non-food categories declined $47.1 million, or 6.6%, to $664.7 million in 2020, which was 74.8% of our total gross profit. The decline in food/non-food gross profit in 2020 was driven primarily by the impact of the COVID-19 pandemic and the shift in sales mix away from higher margin product categories such as food and HB&G.

Suppliers
We purchase products for resale from approximately 2,400 active trade suppliers and manufacturers located across the U.S. and Canada. In 2020, we purchased approximately 81% of our products from our top 20 suppliers, with our top two suppliers, Altria Group, Inc. (the parent company of Philip Morris USA, Inc.) and R.J. Reynolds Tobacco Company, accounting for approximately 33% and 25% of our purchases, respectively. We coordinate our purchasing from suppliers by negotiating, on a company-wide basis, special arrangements to obtain volume discounts and additional incentives, while also taking advantage of promotional and marketing incentives offered to us as a wholesale distributor. In addition, buyers in each of our distribution facilities purchase products directly from manufacturers, improving product mix and availability for individual markets.
Operations
As of December 31, 2020, we operated a network of 32 distribution centers in the U.S. and Canada (excluding two distribution facilities we operate as a third-party logistics provider). Twenty-seven of our distribution centers are located in the U.S. and five are located in Canada.
The map below depicts the scope of our operations and the names of our distribution centers.
core-20201231_g2.jpg
We operate five consolidation centers which buy products from our suppliers in bulk quantities and then redistribute the products to many of our other distribution centers. The products purchased by our consolidation centers may include frozen and chilled items, candy, snacks, beverages, health and beauty care and general merchandise products. We operate two additional facilities as a third-party logistics provider dedicated solely to supporting the logistics and management requirements of one of our major customers, Alimentation Couche-Tard, Inc. (“Couche-Tard”). These distribution facilities are located near Phoenix, Arizona and San Antonio, Texas.

Table of Contents
Our proprietary Distribution Center Management System platform provides our distribution centers with the flexibility to adapt rapidly to changing business needs and allows them to provide our customers with necessary information technology requirements and integration capabilities.
Distribution
As of December 31, 2020, we employed approximately 2,100 personnel in our transportation department, including delivery drivers, shuttle drivers, routers, training supervisors and managers, all of whom focus on achieving safe, on-time deliveries. Our daily orders are picked and loaded nightly in route sequence, with the majority reaching their destination within 24 hours. At December 31, 2020, our distribution fleet consisted of approximately 1,600 leased tractors and trailers and approximately 1,100 additional owned tractors and trailers. Our “tri-temp” trailer fleet gives us the capability to deliver frozen, chilled and non-refrigerated goods in one delivery and provides us the multiple temperature zone capability needed to support our focus on delivering fresh products to our customers. Substantially all of our trailers were “tri-temp” as of December 31, 2020.
A portion of our fleet runs on Compressed Natural Gas (“CNG”), which allows us to reduce our carbon footprint and lower our transportation costs. We utilize seven CNG stations, two of which we own (located in Wilkes-Barre, Pennsylvania and Corona, California). The other five are owned and operated by U.S. Oil (a division of U.S. Venture, Inc.) under the name GAIN Clean Fuel (“GAIN”) and are located in Aurora, Colorado; Forrest City, Arkansas; Sanford, North Carolina; Atlanta, Georgia; and Tampa, Florida. In addition to providing fuel to our fleet, the GAIN stations are also open to other public fleets for fueling.
Competition
Competition within the industry is based primarily on the range and quality of the services provided, price, product selection and the reliability of wholesalers’ logistics as well as proximity to the customer’s stores. We operate from a perspective that focuses heavily on flexibility and providing outstanding customer service, order fulfillment rates, on-time delivery, innovative marketing solutions and merchandising support as well as competitive pricing.
Core-Mark is one of the two largest wholesale convenience distributors (measured by annual sales) serving North America. We service both convenience store chain customers and independent operators with ten or fewer stores which comprise approximately 65% of the convenience retail store market. The McLane Company, Inc., a subsidiary of Berkshire Hathaway Inc., our largest competitor, focuses primarily on servicing large regional or national convenience store chains as well as chain customers in other trade channels. There are two other large companies that primarily cover the eastern half of the U.S.: H.T. Hackney Company and Eby-Brown Company, a division of Performance Food Group. In addition, there are many local distributors serving small regional chains and independent convenience retailers. In Canada, in addition to Core-Mark, several companies make-up the competitive landscape. Wallace & Carey, Inc., has national distribution capabilities. Sobeys Inc. is a large national convenience store and grocery wholesaler.
Beyond the traditional wholesale supply channels, we face potential competition from at least three other supply avenues. First, certain consumer product manufacturers such as Anheuser-Busch Companies, Inc., MillerCoors LLC, The Coca-Cola Company, and PepsiCo (including its Frito-Lay, Inc. division) deliver their products directly to convenience retailers. Secondly, club wholesalers such as Costco Wholesale Corporation and Sam’s West, Inc. (“Sam’s Club”) provide a limited selection of products at generally competitive prices; however, they often have limited delivery options and limited services. Finally, some large convenience retail chains self-distribute products due to the geographic density of their stores and their belief that they can economically service such locations.
We face competition from the diversion into certain U.S. and Canadian markets of cigarettes intended for sale outside of these markets, including the sale of cigarettes in non-taxable jurisdictions, inter-state/provincial and international smuggling of cigarettes, the sale of counterfeit cigarettes by third parties, the sale of cigarettes by third parties over the internet and by other means designed to avoid collection of applicable taxes. The competitive environment also continues to face a continued influx of generic products, tobacco, and nicotine alternatives that challenge sales of higher priced cigarettes.
Working Capital Practices
We sell products on credit terms to our customers that averaged, as measured by days sales outstanding, about nine days for each of 2020, 2019 and 2018. Credit terms may impact pricing and are competitive within our industry. Many of our customers remit payment electronically, which facilitates efficient and timely monitoring of payment risk. Canadian days sales outstanding in receivables tend to be lower as Canadian industry practice is for shorter credit terms than in the U.S.
We maintain our inventory of products based on the level of sales of the particular product and manufacturer replenishment cycles. The number of days a particular item of inventory remains in our distribution centers varies by product and is principally driven by the turnover of that product and economic order quantities. We typically order and carry in
6

Table of Contents
inventory additional amounts of certain critical products to assure high order fulfillment levels for these items. Periodically, we may carry higher levels of inventory to take advantage of anticipated manufacturer price increases. The number of days of cost of sales in inventory averaged about 18 days, 17 days and 14 days, in 2020, 2019 and 2018, respectively. The cigarette category averaged 14 days, 12 days and 7 days, in 2020, 2019 and 2018, respectively. The food/non-food categories averaged 27 days, 27 days and 25 days in 2020, 2019 and 2018, respectively.
We obtain terms from our vendors and certain taxing jurisdictions based on industry practices, consistent with our credit standing. We take advantage of the full complement of term offerings, which may include enhanced cash discounts for earlier payment or prepayment. Terms for our accounts payable and cigarette and tobacco taxes payable range anywhere from three days prepaid to 120 days credit. Days payable outstanding for both categories, excluding the impact of prepayments, averaged 10 days, 10 days and 11 days, in 2020, 2019 and 2018, respectively.

Four of our distribution centers, Hayward, Las Vegas, Los Angeles and Calgary, have employees who are covered by collective bargaining agreements with local affiliates of The International Brotherhood of Teamsters (Hayward, Las Vegas and Los Angeles) and the United Food and Commercial Workers International Union (Calgary). Approximately 400 employees, or 5% of our workforce, are unionized. There have been no disruptions in customer service, strikes, work stoppages or slowdowns as a result of union activities, and we believe we have satisfactory relations with our employees.
We consider our employees to be the foundation for our growth and are critical to our continued success. As such, we believe that the future of Core-Mark depends in large part on our ability to attract, train, retain, and motivate qualified personnel. Helping our Core-Mark family grow and develop to reach their full potential is an integral part of our core values. We are also committed to cultivating and fostering a culture of diversity and inclusion and appreciate that the Company’s ultimate success is linked to its ability to identify and hire talented individuals from all backgrounds and perspectives.
Regulation
As a distributor of food, nicotine and health-related products in the U.S., we are subject to the Federal Food, Drug and Cosmetic Act and regulations promulgated by the U.S. Food and Drug Administration (“FDA”). In Canada, similar standards related to food and over-the-counter medications are governed by Health Canada. The products we distribute are also subject to federal, state, provincial and local regulation through such measures as: the licensing of our facilities; enforcement by state, provincial and local health agencies of relevant standards for the products we distribute; and regulation of our trade practices in connection with the sale of our products. Our facilities are inspected periodically by federal, state, provincial and local authorities, including the Occupational Safety and Health Administration (“OSHA”) under the U.S. Department of Labor, which require us to comply with certain health and safety standards to protect our employees.
We are also subject to regulation by the U.S. and Canadian Departments of Transportation, and similar state, provincial and local agencies. Our distribution centers in the U.S. and Canada are subject to a broad spectrum of federal, state, provincial and local environmental protection statutes including those that govern emissions to air, soil and water, and the disposal of hazardous substances.
Our policy is to comply with all regulatory and legal requirements, and management is not aware of any related issues that may have a material effect upon our business, financial condition or results of operations.
Trademarks
We have trademarks including the following: Arcadia Bay®, Arcadia Bay Coffee Company®, Cable Car®, Core-Mark®, Core Solutions Group®, EMERALD®, Java Street®, SmartStock®, Pine State Convenience™, Taco Depot® and Farner-Bocken™.

Segment and Geographic Information
We have two operating segments which aggregate into one reportable segment. We also present certain financial information by operating segment region — the U.S. and Canada. See Note 16 - Segment and Geographic Information to our consolidated financial statements.
Seasonality
We typically generate higher net sales and gross profits during the warm weather months (April through September) than other times of the year. This occurs because the convenience store industry benefits from miles traveled and outdoor activity which accelerates during the summer months.

ITEM 1A.     RISK FACTORS
Our business is subject to a variety of risks. Set forth below are certain of the important risks that we face, the occurrence of which may have a material effect on our business, financial condition or results of operations.
Risks Related to Our Business and Industry
The novel coronavirus (or “COVID-19”) pandemic and the responsive actions taken by governments and others to mitigate its spread have significantly impacted worldwide economic conditions and could have a material adverse effect on our operations and business.
The COVID-19 pandemic and the responsive actions taken by governments and others, including mandatory and voluntary closures, shelter-in-place orders and social distancing protocols, began to adversely impact our operations late in the first quarter of 2020 and are likely to continue to affect our business for an indeterminate amount of time. These actions could materially adversely affect our ability to adequately staff and maintain our operations, cause disruptions in the supply chain and impact our ability to maintain adequate inventory and liquidity. While we and the vast majority of our customers have been permitted to continue to operate as essential businesses, the unprecedented impact of the COVID-19 pandemic, including an increase in the level of shelter-in-place orders by states, provinces, cities and counties, has resulted in a significant downturn in miles driven, causing a substantial decline in convenience retail store visits across North America. In addition to adversely affecting our revenues, the decrease in convenience retail store visits could also negatively impact our customers’ ability to pay for our goods and services or cause some customers’ businesses to fail. The COVID-19 pandemic has produced significant shifts in the mix of our business with a larger decline in food/non-food sales relative to cigarette sales, which we anticipate will result in lower gross margins until the impacts of the COVID-19 pandemic dissipate. As we cannot predict the duration or scope of the COVID-19 pandemic, the anticipated negative financial impact to our operating results cannot be reasonably estimated, but could be material and last for an extended period of time.
A significant portion of our sales volume is dependent upon the distribution of cigarettes, sales of which are generally declining.
The distribution of cigarettes is currently a significant portion of our business. In 2020, approximately 66.7% of our net sales (including excise taxes) and 25.2% of our gross profit were generated from the distribution of cigarettes. Due to increases in the prices of cigarettes, increases in cigarette regulation and excise taxes, health concerns, increased pressure from anti-tobacco groups, the rise in popularity of tobacco alternatives, including electronic cigarettes, other alternative nicotine products, and other factors, cigarette consumption in the U.S. and Canada has been declining gradually over the past few decades. In many instances, tobacco alternatives, such as electronic cigarettes, are not subject to federal, state, provincial and local excise taxes like the sale of conventional cigarettes or other tobacco products. We expect consumption trends of legal cigarette products will continue to be negatively impacted by the factors described above. In addition, rising prices may lead to a higher percentage of consumers purchasing cigarettes through illicit markets, or by other means designed to avoid payment of cigarette taxes. If we are unable to sell other products to make up for these declines in cigarette unit sales, our operating results may suffer.
We are largely dependent on the convenience retail industry, and our results of operations could suffer if it experiences an overall decline or consolidation.
The majority of our sales are generated from convenience retail stores which inherently involve industry-specific risks. These risks include: declining sales in the convenience retail industry due to general economic conditions, including rising energy and fuel costs, which may impact “in-store” retail sales; competition from internet retailers such as Amazon.com, Inc. (“Amazon”), club stores, grocery stores and other retail outlets; termination of customer relationships; and consolidation of our customer base. Such events could cause us to experience decreases in revenues, put pressure on our margins and increase our credit risk and potential bad debt exposure.
We depend on attracting and retaining qualified labor including our senior management and other key personnel.
We depend on the continued services and performance of our senior executive officers as named in our Proxy Statement and other key employees. We do not maintain key person life insurance policies on these individuals. The loss of the services of one or more of our senior executive officers or other key personnel could harm our business.
We compete with other businesses in each of our markets to attract and retain qualified employees. A shortage of qualified employees in any given market could require us to enhance our wage and benefit packages in order to compete effectively in the hiring and retention of qualified employees or to hire more expensive temporary employees in the affected market. Any such shortage of qualified employees could decrease our ability to effectively serve our customers and might lead to lower profits due to higher labor costs.
10

Table of Contents
Our ability to meet our labor needs is generally subject to numerous other external factors, including prevailing wage rates, changing demographics, health and other insurance costs, and adoption of new or revised employment and labor laws and regulations. These external factors could prevent us from locating, attracting or retaining qualified personnel, which could adversely impact the quality of the services we provide to our customers, as well as our financial performance.
Many of the markets in which we compete are highly competitive and we may lose market share and suffer a decline in sales and profitability in these markets if we are unable to outperform our competition.
Our distribution centers operate in highly competitive markets. A substantial amount of our sales are made under non-binding agreements or short-term contracts with convenience retail stores which inherently involve potential risks. We face competition from local, regional and national tobacco and consumable products distributors on the basis of service, price, reliability, delivery schedules, and variety of products offered. We also face competition from club stores and alternate sources that sell consumable products to convenience retailers. Some of our competitors, including The McLane Company, Inc. (a subsidiary of Berkshire Hathaway Inc.), have substantial financial resources and long-standing customer relationships. In addition, heightened competition among our existing competitors, or by new entrants into the distribution market, could create additional competitive pressures that may result in the loss of major customers, reduced margins, or other adverse effects on our business. If we fail to successfully respond to these competitive pressures or to implement our strategies effectively, we may lose market share, and our results of operations could suffer.
Our ability to operate effectively could be impaired by the risks and costs associated with expansion activities.
Our business continues to expand and market share growth is one of our key company initiatives. To accomplish this growth, we have focused on strategic acquisitions and securing regional and national customers as key elements of success. Any significant expansion activity comes with inherent risks. Acquisitions may entail various risks, such as identifying suitable candidates, realizing acceptable rates of return on investment, identifying potential liabilities, obtaining adequate financing, negotiating acceptable terms and conditions, and successfully integrating operations and converting systems post acquisition. Integrating a large new customer has similar risks related to realizing acceptable returns on invested working capital and negotiating acceptable pricing and service levels, while managing resources and business interruptions as we integrate the new business into our current infrastructure. We may realize higher costs, lower margins or fewer benefits than originally anticipated and may experience disruption to our base business in connection with such acquisitions and other new customer integration activities.
Our failure to maintain relationships with large customers could potentially harm our business.
We have relationships with many large regional and national convenience and other store chains. While we expect to maintain these relationships for the foreseeable future, any termination, non-renewal or reduction in services that we provide to such customers could cause our revenues and operating results to suffer.
We may lose business if manufacturers or large retail customers convert to direct distribution of their products.
In the past, certain large manufacturers and customers have elected to engage in direct distribution or third-party distribution of their products and ceased relying on wholesale distributors such as Core-Mark. Similarly, manufacturers or other providers may choose to move their product distribution to Amazon or other e-commerce providers. If other manufacturers or retail customers make similar elections in the future, our revenues and profits would be adversely affected and there can be no assurance that we will be able to mitigate such losses.
Our business is sensitive to fuel prices and related transportation costs, which could adversely affect our business.
Our operating results may be adversely affected by unexpected increases in fuel or other transportation-related costs, including costs from the use of third-party carriers, temporary staff and overtime. Historically, we have been able to pass on a substantial portion of increases in our own fuel or other transportation costs to our customers in the form of fuel or delivery surcharges, but our ability to continue to pass through these increases is not assured. If we are unable to continue to pass on fuel and transportation-related cost increases to our customers, do not realize the benefits we expect from converting a large percentage of our trucks to operate on natural gas or incur higher expenses due to decreases in diesel fuel prices that are not matched by similar decreases in natural gas prices, our operating results could be negatively affected.
Information technology systems may be subject to failure, disruptions, security breaches (such as malware, viruses, hacking, break-ins, business e-mail compromises, phishing attacks, attempts to overload our services or other cyber-attacks) which could compromise our ability to conduct business, seriously harm our business and adversely affect our financial results.
Our business is highly dependent on our enterprise information technology systems. We rely on these systems and our information technology staff to maintain the information required to operate our distribution centers and support corporate
11

Table of Contents
departments in providing our customers with fast, efficient and reliable services. We continue to take steps to increase redundancy in our information technology systems and have resiliency and recovery plans in place to mitigate events that could disrupt our systems’ service. However, if our systems fail or are not reliable, we may suffer disruptions in service to our customers and our results of operations could suffer.
In addition, we retain sensitive data, including intellectual property, proprietary business information and personally identifiable information, in our secure data centers and on our networks. As the number of global cyber-attacks continue to escalate, we may face increased threats of unauthorized access, security breaches and other system disruptions to our environment. To help mitigate the risk, we utilize the expertise of internal and external security resources to monitor our environment and install/upgrade tools that protect our systems and data. We strive to maintain a sustainable security program that balances the need to protect against the needs to run our business, however, despite these measures, our infrastructure may be vulnerable to attacks by experienced hackers or other disruptive events as “perfect protection” is unfortunately not possible.
Computer malware, viruses, hacking, break-ins, business e-mail compromises, phishing attacks, attempts to overload our servers and other cyber-attacks have become more prevalent and may occur on our systems in the future. Intruders may also take the form of parties that attempt to fraudulently induce employees or other users of our systems to disclose sensitive or confidential information, make unauthorized cash payments or funds transfers, or otherwise disrupt operations. Any such security breach may compromise information stored on our networks and may result in significant data losses or theft of intellectual property, proprietary business information or personally identifiable information belonging to us or our customers, business partners or employees. Though it is difficult to determine what, if any, harm may directly result from any specific interruption or attack, any failure to maintain performance, reliability and security affects the availability of our technical infrastructure and technology-based services. Any such failure may harm our reputation and our ability to retain existing customers and attract new customers and could impact our results of operation. We attempt to address these risks, in part, by continuously providing communications to our employees regarding the threats and characteristics of phishing attempts and have established a formal ongoing security training program to increase the level of awareness across the Company.
In many cases our systems are integrated with customers and vendors, through enterprise resource planning, electronic data interchange or other integration. Accordingly, if our customers’ or vendors’ systems are compromised, fail, or are not reliable, we may suffer disruptions in services to customers, our payments to vendors may be delayed or could be misappropriated, and our results of operations and cash flows could suffer.
Cigarette and consumable goods distribution is a low-margin business sensitive to inflation and deflation.
We derive most of our revenues from the distribution of cigarettes, other tobacco products, candy, snacks, fast food, groceries, fresh products, dairy, beverages, general merchandise and health and beauty care products. Our industry is characterized by a high volume of sales with low profit margins. Our food/non-food sales are generally priced based on the manufacturer’s cost of the product plus a percentage markup. As a result, our profit levels may be negatively impacted during periods of cost deflation or stagnation for these products, even though our gross profit as a percentage of the price of goods sold may remain relatively constant. In addition, periods of product cost inflation may have a negative impact on our gross profit margins with respect to sales of cigarettes because gross profits on cigarette sales are generally fixed on a cents per carton basis. Therefore, as cigarette prices increase, gross profit generally decreases as a percentage of sales. In addition, if the cost of the cigarettes that we purchase increases due to manufacturer price increases, reduced or eliminated manufacturer discounts and incentive programs, or increases in applicable excise tax rates, our inventory carrying costs and accounts receivable could rise, placing pressure on our working capital requirements.
We rely on manufacturer discount and incentive programs and cigarette excise stamping allowances, and any material changes in these programs could adversely affect our results of operations.
We receive payments from manufacturers on the products we distribute for allowances, discounts, volume rebates and other merchandising and incentive programs. These payments are a substantial contributor to our gross profit. The amount and timing of these payments are affected by changes in the programs by manufacturers, our ability to sell specified volumes of a particular product, attaining specified levels of purchases by our customers and the duration of carrying a specified product. In addition, we receive discounts from certain taxing jurisdictions in connection with the collection of excise taxes. If manufacturers or taxing jurisdictions change or discontinue these programs or change the timing of payments, or if we are unable to maintain the volume of our sales required by such programs, our results of operations could be negatively affected.
We depend on relatively few suppliers for a large portion of our products, and any interruptions in the supply of the products that we distribute could adversely affect our results of operations.
We obtain the products we distribute from third-party suppliers. At December 31, 2020, we had approximately 2,400 vendors and during 2020 we purchased approximately 81% of our products from our top 20 suppliers, with purchases from our top two suppliers, Altria Group, Inc. (parent of Philip Morris USA, Inc.) and R.J. Reynolds Tobacco Company, representing
12

Table of Contents
approximately 33% and 25% of our purchases, respectively. We do not have any long-term contracts with our suppliers committing them to provide products to us. Our suppliers may not provide the products we distribute in the quantities we request on favorable terms, or at all. We are also subject to delays caused by interruptions in production due to conditions outside our control, such as slow-downs or strikes by employees of suppliers, inclement weather, transportation interruptions, regulatory requirements and natural disasters. Our inability to obtain adequate supplies of the products we distribute could cause us to fail to meet our contractual and other obligations to our customers and reduce the volume of our sales and profitability.
We may be subject to product liability claims and counterfeit product claims which could materially adversely affect our business.
As a distributor of food and consumer products, we face the risk of exposure to product liability claims in the event that the use of a product sold by us causes injury or illness. In addition, certain products that we distribute may be subject to counterfeiting. Our business could be adversely affected if consumers lose confidence in the safety and quality of the food and other products we distribute. Further, our operations could be subject to disruptions as a result of manufacturer recalls. This risk may increase as we continue to expand our distribution of food products. If we do not have adequate insurance, if contractual indemnification from the supplier or manufacturer of the defective, contaminated or counterfeit product is not available, or if a supplier or manufacturer cannot fulfill its indemnification obligations to us, the liability relating to such product claims or disruption as a result of recall efforts could adversely impact our results of operations.
We may not be able to achieve the expected benefits from the implementation of marketing and category management initiatives.
We are continuously improving our competitive performance through a series of strategic marketing and category management initiatives, such as our Focused Marketing Initiative, SmartStock and Vendor Consolidation Initiative. The goal of this effort is to develop and implement a comprehensive and competitive business strategy, addressing the special needs of the convenience industry environment, increasing our market position within the industry and ultimately creating increased stockholder value. Customer acceptance of new marketing or category management initiatives may not be as anticipated or competitive pressures may cause us to curtail or abandon these initiatives, resulting in lower revenue and profit growth.
Maintaining our brand and reputation is necessary for the success of our business.
Our established brand and reputation within the market largely contributes to our success. Our current and future business could be negatively impacted if we were poorly represented or garnered negative publicity through various media channels, which include but are not limited to print, broadcast, web-based and social media. Brand value is based in large part on perceptions of subjective qualities, and even isolated incidents can erode trust and confidence, particularly if they result in adverse publicity, governmental investigations or litigation. Even if the aforementioned situations were unfounded or not material to our business, these events could still decrease demand for our products and services and erode customer confidence. If any of these events were to occur, they could have a negative impact on our results of operations and financial condition.
We may be subject to various claims and lawsuits that could result in significant expenditures.
The nature of our business exposes us to the potential for various claims and litigation related to labor and employment, personal injury, property damage, business practices, environmental liability and other matters. Any material litigation or a catastrophic accident or series of accidents could have a material adverse effect on our business, financial position, results of operations and cash flows.
Unions may attempt to organize our employees.
As of December 31, 2020, approximately 5% of our 7,534 employees were covered by collective bargaining agreements with labor organizations, under agreements that expire at various times. We cannot assure that we will be able to renew our respective collective bargaining agreements on favorable terms, that employees at other facilities will not unionize or that our labor costs will not increase. In addition, we are subject to changes in rules, regulations, and laws that could impact our ability to manage our labor force and wage successful campaigns preventing further unionization of our employees. To the extent we suffer business interruptions as a result of strikes or other work stoppages or slow-downs, or our labor costs increase and we are not able to recover such increases through increased prices charged to customers or offsets by productivity gains, our results of operations could be materially adversely affected.
Employee health benefit costs represent a significant expense to us and may negatively affect our profitability.
With approximately 5,400 employees and their families participating in our health plans, our expenses relating to employee health benefits are substantial. In past years, we have experienced significant increases in certain of these costs, largely as a result of economic factors beyond our control, including, in particular, ongoing increases in health care costs well in
13

Table of Contents
excess of the rate of inflation. Increased participation in our health plans, continued increasing health care costs, as well as changes in laws, regulations and assumptions used to calculate health and benefit expenses, may adversely affect our business, financial position and results of operations. In addition, the Patient Protection and Affordable Care Act (“ACA”) may continue to increase our employee healthcare-related costs. We have migrated a significant number of employees to our high deductible plan, resulting in a reduction in our claims exposure and offsetting other costs related to ACA. While we have taken steps to minimize the impact of ACA, there is no guarantee our efforts will be successful.
Changes to minimum wage laws and other governmental legislation or regulations could increase our costs substantially.
As of December 31, 2020, we believe we had no employees who were paid under the minimum wage in their respective locations. Several bills have been introduced in the U.S. legislature over the past few years to increase the federal minimum wage. In addition, several states have adopted or are considering adopting minimum wage statutes that exceed the federal minimum wage rate. Any increases in federal or state minimum wages could require us to increase the wages paid to our minimum wage employees and create pressure to raise wages for other employees who already earn above-minimum wages. Further, changes to wage and hour laws and/or new legislation increasing mandatory paid leave can add costs to our business. If we are unable to pass these additional labor costs on to our customers in the form of increased prices or surcharges, our business and results of operations would be adversely affected.
If we are unable to comply with governmental regulations that affect our business or if there are substantial changes in these regulations, our business could be adversely affected.
As a distributor of food, tobacco and nicotine items, products containing cannabidiol and other consumer goods, we are subject to regulation by the FDA, Health Canada and similar regulatory authorities at the federal, state, provincial and local levels. In addition, our employees operate tractor trailers, trucks, forklifts and various other powered material handling equipment, and we are therefore subject to regulation by the U.S. and Canadian Departments of Transportation. Our operations are also subject to regulation by OSHA, the U.S. Drug Enforcement Administration and a myriad of other federal, state, provincial and local agencies. Each of these regulatory authorities has broad administrative powers with respect to our operations. Regulations, the uncertainty and pace of regulatory change and the costs of complying with those regulations, have been increasing in recent years. If we fail to adequately comply with government regulations, we could experience increased inspections or audits, regulatory authorities could take remedial action including imposing fines, suspending or canceling our licenses, or shutting down our operations, or we could be subject to increased compliance costs. If any of these events were to occur, our results of operations would be adversely affected.
Natural disaster damage could have a material adverse effect on our business.
Several of our warehouses in California, and one warehouse located near Vancouver, British Columbia, Canada, are in or near high hazard earthquake zones. We also have operations in areas that have been affected by natural disasters such as hurricanes, tornados, floods, and ice and snow storms. While we maintain insurance to cover us for certain potential losses, our insurance may not be sufficient in the event of a significant natural disaster, or payments under our policies may not be received timely enough to prevent adverse impacts on our business. Our customers could also be affected by similar events, which could adversely affect our sales and results of operations. While we maintain two data centers in geographically disparate locations, each of which can provide core services for the other if required, in the event of a natural disaster our insurance may not be sufficient to cover our losses, insurance payments may be delayed and our business may nevertheless be interrupted and adversely affected.
Insurance and claims expenses could have a material adverse effect on us.
We have a combination of both self-insurance and high-deductible insurance programs for the risks arising out of the services we provide and the nature of our operations throughout North America, including claims exposure resulting from personal injury, property damage, business interruption and workers’ compensation. Workers’ compensation, automobile and general liabilities are determined using actuarial estimates of the aggregate liability for claims incurred and an estimate of incurred but not reported claims. Our accruals for insurance reserves reflect certain actuarial assumptions and management judgments, which are subject to a high degree of variability. If the number or severity of claims for which we are retaining risk increases, our financial condition and results of operations could be adversely affected. If we lose our ability to self-insure these risks, our insurance costs could materially increase and we may find it difficult to obtain adequate levels of insurance coverage.

Risks Related to the Distribution of Cigarettes and Other Tobacco Products
Legislation, regulation and other matters are negatively affecting the cigarette, tobacco and alternative nicotine industries.
The cigarette, tobacco and alternative nicotine industries are subject to a wide range of laws and regulations regarding the marketing, distribution, sale, taxation and use of their products imposed by governmental entities. Effective December 20, 2019, the U.S. raised the legal age to buy cigarettes, tobacco and alternative nicotine products to 21 years. On January 2, 2020, the FDA issued final guidance that banned most flavored cartridge-based e-cigarettes, except for tobacco and menthol flavors. The guidance temporarily permits the sale of e-liquid flavors used in open vaping systems and in disposable, single-use vape products. In addition, various jurisdictions have adopted or are considering legislation and regulations restricting displays and marketing of tobacco and alternative nicotine products, requiring the disclosure of ingredients used in the manufacture of tobacco and alternative nicotine products, and imposing restrictions on public smoking and vaping. The FDA has been empowered to regulate changes to nicotine yields and the chemicals and flavors used in tobacco and alternative nicotine products (including cigars, pipe and e-cigarette products), require ingredient listings be displayed on tobacco and alternative nicotine products, prohibit the use of certain terms which may attract youth or mislead users as to the risks involved with using tobacco and alternative nicotine products, as well as limit or otherwise impact the marketing of tobacco and alternative nicotine products by requiring additional labels or warnings that must be pre-approved by the FDA. Such legislation and related regulation is likely to continue adversely impacting the market for tobacco and alternative nicotine products and, accordingly, our sales of such products.
In Canada, several provinces have enacted legislation authorizing and facilitating the recovery by provincial governments of tobacco-related health care costs from the tobacco industry by way of lawsuit. Some Canadian provincial governments have either already initiated lawsuits or indicated an intention that such lawsuits will be filed. It is unclear at this time how such restrictions and lawsuits may affect Core-Mark and its Canadian operations.
Our distribution of cigarettes and other tobacco products exposes us to potential liabilities.
In June 1994, the Mississippi attorney general brought an action against various tobacco industry members on behalf of the state to recover state funds paid for health care costs related to tobacco use. Most other states sued the major U.S. cigarette manufacturers based on similar theories. In November 1998, the major U.S. tobacco product manufacturers entered into a Master Settlement Agreement (“MSA”) with 46 states, the District of Columbia and certain U.S. territories. The other four states: Mississippi, Florida, Texas and Minnesota (“non-MSA states”), settled their litigations with the major cigarette manufacturers by separate agreements. The MSA and the other state settlement agreements settled health care cost recovery actions and monetary claims relating to future conduct arising out of the use of, or exposure to, tobacco products, imposed a stream of future payment obligations on major U.S. cigarette manufacturers and placed significant restrictions on the ability to market and sell cigarettes. The payments required under the MSA result in higher pricing of products sold by the participating manufacturers than those sold by non-MSA state manufacturers. In addition, the growth in market share of discount brands since the MSA was signed has had an adverse impact on the total volume of the cigarettes that we sell.
In connection with the MSA, we were indemnified by most of the tobacco product manufacturers from which we purchased cigarettes and other tobacco products, for liabilities arising from our sale of the tobacco products that they supplied to us. Should the MSA ever be invalidated, we could be subject to substantial litigation due to our distribution of cigarettes and other tobacco products, and we may not be indemnified for such costs by the tobacco product manufacturers in the future. In addition, even if we are indemnified by cigarette manufacturers that are parties to the MSA, future litigation awards against such cigarette manufacturers could be so large as to prevent the manufacturers from satisfying their indemnification obligations.
Risks Related to Financial Matters, Financing and Foreign Exchange
If a tax jurisdiction changes its tax legislation or a material change occurs in our credit terms, it could have a material adverse effect on our business and results of operations.
From time to time, new tax legislation is adopted by the federal government and various states or other regulatory bodies. Significant changes in tax legislation or administrative policies in any taxing jurisdiction could adversely affect our business or results of operations in a material way.  Increases in federal or state excise taxes, differing interpretation of tax law, final determination of a tax audit or a reduction in credit terms could materially impact our financial results and restrict our working capital.
Cigarettes and tobacco products are subject to substantial excise taxes in the U.S. and Canada. Significant increases in cigarette-related taxes and/or fees have been proposed or enacted and are likely to continue to be proposed or enacted by various taxing jurisdictions within the U.S. and Canada as a means of increasing government revenues. These tax increases
15

Table of Contents
may negatively impact consumption. Additionally, they may cause a shift in sales from premium brands to discount brands, illicit channels or tobacco alternatives, such as electronic cigarettes, as smokers seek lower priced options.
In addition, in the U.S. the federal government has in the past proposed legislation which effectively could limit, or even eliminate, use of the last-in, first-out (“LIFO”) inventory method for financial and income tax purposes. Although the final outcome of any such proposals cannot be ascertained, the ultimate financial impact to us of the transition from LIFO to another inventory method could be material to our operating results. Given the unpredictability of possible changes and their potential interdependency, it is very difficult to assess whether the overall effect of such potential tax changes would be cumulatively positive or negative for our earnings and cash flow, but such changes could adversely impact our financial results.
Taxing jurisdictions have the ability to change or rescind credit terms currently extended for the remittance of taxes that we collect on their behalf. If these excise taxes are substantially increased, or credit terms are substantially reduced, it could have a negative impact on our liquidity. Accordingly, we may be required to obtain additional debt financing, which we may not be able to obtain on satisfactory terms or at all.
There can be no assurance that we will continue to declare cash dividends in the future or in any particular amounts and if there is a reduction in dividend payments, our stock price may be harmed.
Since the fourth quarter of 2011, we have paid a quarterly cash dividend to our stockholders. We intend to continue to pay quarterly dividends subject to capital availability and periodic determinations by our Board of Directors that cash dividends are in the best interest of our stockholders and are in compliance with all applicable laws and agreements to which we are a party. Future dividends may be affected by a variety of factors such as available cash, anticipated working capital requirements, overall financial condition, credit agreement restrictions, future prospects for earnings and cash flows, capital requirements for acquisitions, stock repurchase programs, reserves for legal risks and changes in federal and state income tax or corporate laws. Our Board of Directors may, at its discretion, decrease or entirely discontinue the payment of dividends at any time. Any such action could have a material, negative effect on our stock price.
Currency exchange rate fluctuations could have an adverse effect on our revenues and financial results.
We generate a portion of our revenues in Canadian dollars, approximately 10% in 2020 and 9% in 2019. We also incur a significant portion of our expenses in Canadian dollars. To the extent that we are unable to match revenues received in Canadian dollars with costs paid in the same currency, exchange rate fluctuations in Canadian dollars could have an adverse effect on our financial results. During times of a strengthening U.S. dollar, our reported sales and earnings from Canadian operations will be reduced because the Canadian currency will be translated into fewer U.S. dollars. Conversely, during times of a weakening U.S. dollar, our reported sales and earnings from our Canadian operations will be increased because the Canadian currency will be translated into more U.S. dollars. U.S. GAAP requires that foreign currency transaction gains or losses on short-term intercompany transactions be recorded currently as gains or losses within the consolidated statement of operations. To the extent we incur losses on such transactions, our net income will be reduced. We currently do not hedge our Canadian foreign currency cash flows.
We may not be able to borrow additional capital to provide us with sufficient liquidity and capital resources necessary to meet our future financial obligations.
We expect that our principal sources of funds will be cash generated from our operations and, if necessary, borrowings under a $750 million revolving credit facility (“Credit Facility”) as of December 31, 2020. The Credit Facility, initially dated as of October 12, 2005, as amended or otherwise modified from time to time, is between us, as Borrowers, the Lenders named therein, and JPMorgan Chase Bank, N.A., as administrative agent. The Credit Facility expires in February 2026. While we believe our sources of liquidity are adequate, we cannot guarantee that these sources will be available or continue to provide us with sufficient liquidity and capital resources required to meet our future financial obligations, or to provide funds for our working capital, capital expenditures and other needs. As such, additional equity or debt financing sources may be necessary and we may not be able to expand our existing Credit Facility or obtain new financing on terms satisfactory to us.
Our operating flexibility is limited in significant respects by the restrictive covenants in our Credit Facility.
Our Credit Facility imposes restrictions on us that could increase our vulnerability to general adverse economic and industry conditions by limiting our flexibility in planning for and reacting to changes in our business and industry. Specifically, these restrictions place limits on our ability to, among other things, incur additional indebtedness, pay dividends, issue stock of subsidiaries, make investments, repurchase stock, create liens, enter into transactions with affiliates, merge or consolidate, or transfer and sell our assets. In addition, under our Credit Facility, under certain circumstances we are required to meet a fixed charge coverage ratio. Our ability to comply with this covenant may be affected by factors beyond our control and a breach of the covenant could result in an event of default under our Credit Facility, which would permit the lenders to declare all amounts incurred thereunder to be immediately due and payable and to terminate their commitments to make further extensions of credit.

Market and Stockholders
Our common stock trades on the NASDAQ Global Market under the symbol “CORE.” According to the records of our transfer agent, we had 1,291 stockholders of record as of February 22, 2021.
We paid cash dividends of $22.0 million and $20.8 million in 2020 and 2019, respectively. Our Credit Facility, as of December 31, 2020, allows for unlimited dividends, as long as we meet certain credit availability percentages and fixed charge coverage ratios. (See Note 8 - Long-term Debt to our consolidated financial statements included in this Form 10-K for additional details on the Credit Facility). We intend to continue increasing our dividends per share over time; however, the payment of any future dividends will be determined by our Board of Directors in light of then existing conditions, including our earnings, financial condition and capital requirements, strategic alternatives, restrictions in financing agreements, business conditions and other factors.

PERFORMANCE COMPARISON

The graph below presents a comparison of cumulative total return to stockholders for Core-Mark’s common stock at the end of each year from 2015 through 2020, as well as the cumulative total returns of the Russell 2000 Index, the NASDAQ Non-financial Stock Index, the Standard and Poor’s (“S&P”) SmallCap 600 Index, and a peer group of companies (“Performance Peer Group”).
Cumulative total return to stockholders is measured by the change in the share price for the period, plus any dividends, divided by the share price at the beginning of the measurement period. Core-Mark’s cumulative stockholder return is based on an investment of $100 on December 31, 2015, and is compared to the total return of the Russell 2000 Index, the NASDAQ Non-financial Index, the S&P SmallCap 600 Index, and the weighted-average performance of the Performance Peer Group over the same period with a like amount invested, including the assumption that any dividends have been reinvested. We regularly compare our performance to the Russell 2000 Index since it includes primarily companies with relatively small market capitalization similar to us.
The companies composing the Performance Peer Group are: United Natural Foods, Inc. (“UNFI”), Performance Food Group Co. (“PFGC”), AMCON Distributing Co. (“DIT”), and SpartanNash Co. (“SPTN”).

Issuer Purchases of Equity Securities
On February 24, 2020, our Board of Directors authorized a $60.0 million stock repurchase program (the “2020 Program”), replacing our prior stock repurchase program (the “Prior Program”). At the time of approval, we had funds totaling $0.4 million remaining under the Prior Program which were subsequently retired unused. The timing, price and volume of purchases under the 2020 Program are based on market conditions, cash and liquidity requirements, relevant securities laws and other factors.  The 2020 Program may be discontinued or amended at any time. The 2020 Program has no expiration date and terminates when the amount authorized has been expended or the Board of Directors withdraws its authorization.

The following discussion and analysis of financial condition, results of operations, liquidity and capital resources should be read in conjunction with the accompanying audited consolidated financial statements and notes thereto that are included under Part II, Item 8, of this Form 10-K. Also refer to “Special Note Regarding Forward-Looking Statements,” which is included after the Table of Contents in this Form 10-K. This discussion and analysis also includes non-GAAP financial measures that we believe provide important perspective in understanding trends that may impact our business. These non-GAAP financial measures are discussed, including reconciliation of these measures to GAAP, under “Non-GAAP Financial Information.”
This section of this Form 10-K generally discusses 2020 and 2019 items and year-to-year comparisons between 2020 and 2019. Discussions of 2018 items and year-to-year comparisons between 2019 and 2018 are not included in this Form 10-K and can be found in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Part II, Item 7 of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2019 and filed with the Securities and Exchange Commission on March 2, 2020.
Our Business
Core-Mark is one of the largest marketers of fresh, food and broad-line supply solutions to the convenience retail industry in North America. We offer a full range of products, marketing programs and technology solutions to approximately 40,000 customer locations in the U.S. and Canada. Our customers include traditional convenience stores, drug stores, mass merchants, grocery stores, liquor stores, and other specialty and small format stores that carry convenience products. Our product offering includes cigarettes, other tobacco products (“OTP”), alternative nicotine products, candy, snacks, food, including fresh products, groceries, dairy, bread, beverages, general merchandise and health and beauty care products. We operate a network of 32 distribution centers in the U.S. and Canada (excluding two distribution facilities we operate as a third-party logistics provider).

Table of Contents
Business Strategy Overview
Core-Mark’s mission is to be the most valued marketer of fresh, food and broad-line supply solutions to the convenience retail industry. Consistent with this mission, our strategic framework is centered around three key initiatives: growing sales and margins faster than the industry, providing industry-leading category management solutions and leveraging our cost structure. The convenience wholesale and retail industry remains highly fragmented, supporting significant opportunities for both organic growth and growth through strategic acquisitions. Core-Mark is one of the largest wholesale distributors to the convenience retail industry in North America, one of two national convenience distributors in the U.S. and the largest in Canada, and represents an estimated 7% market share of the in-store sales of convenience stores in North America.
Our growth initiatives include elevating same store sales, gaining share of North American convenience stores and being opportunistic with traditional and industry-adjacent acquisition opportunities. While serving traditional convenience retailers remains the primary driver for our business, we serve a wide variety of alternative convenience retail formats including mass merchandisers, casinos, colleges and airports. Driving growth through these alternative convenience retail formats and channels is a core component of our strategy and we see significant opportunities to drive growth organically, through acquisitions and strategic partnerships. Our focus on providing industry-leading category management solutions to our customers positions us to partner with retailers to help increase their sales and profits. We offer a wide array of marketing programs, innovative product alternatives, data aggregation and loyalty solutions to our customers in pursuit of category management excellence. Core-Mark is also actively engaged in efforts to increase the leverage of our operating cost structure through a range of initiatives, including technology investments, centralizing transactional processes and employee engagement aimed at increasing productivity.

We believe consistent execution on the aforementioned strategic priorities will position Core-Mark as the leader in convenience retail distribution and provides a strong pathway to achieve sustainable shareholder returns.
Other Business Developments
The effects of the COVID-19 pandemic had an impact on our operating results during the year ended December 31, 2020, and we expect the pandemic will continue to affect our business for some period of time. While the vast majority of our customers are convenience retailers that continue to operate as essential businesses, the unprecedented impact of the COVID-19 pandemic since the second quarter of 2020, including shelter-in-place orders by states, provinces, cities and counties resulted in a significant downturn in miles driven, resulting in a decline in convenience retail store visits across North America. Although we are seeing recovery as consumer purchase trends improve, we expect future results to continue to be impacted by the effects of the COVID-19 pandemic.

Share Repurchase Program
On February 24, 2020, our Board of Directors authorized a $60.0 million stock repurchase program (the “2020 Program”), replacing our prior stock repurchase program (the “Prior Program”). At the time of approval, we had funds totaling $0.4 million remaining under the Prior Program which were subsequently retired unused. The timing, price and volume of purchases under the 2020 Program are based on market conditions, cash and liquidity requirements, relevant securities laws and other factors.  The 2020 Program may be discontinued or amended at any time. The 2020 Program has no expiration date and terminates when the amount authorized has been expended or the Board of Directors withdraws its authorization.

Table of Contents
In 2020, all stock repurchases were made under the 2020 Program, and we repurchased 407,971 shares of common stock for a total cost of $10.4 million, or an average price of $25.62 per share. As of December 31, 2020, $49.6 million remained available for future share repurchases under the 2020 Program. In 2019, under the Prior Program, we repurchased 767,681 shares of common stock for a total cost of $22.0 million, or an average price of $28.66 per share.

Overview of 2020 Results
During 2020, we continued to build on our sales and operational capabilities, as well as our financial foundation, to drive our long-term growth strategy. We delivered strong financial results and further enhanced our industry-leading offering of products and services despite the backdrop of the COVID-19 pandemic.
Our net sales in 2020 increased 1.7%, or $287.4 million, to $16,957.9 million compared to $16,670.5 million for 2019. The increase in net sales for the year was driven primarily by strong cigarette sales, including increases in cigarette manufacturers’ prices and growth in cigarette carton sales, partially offset by a 2.3% decrease in sales of food/non-food. Sales of cigarettes and food/non-food products for the year were impacted by changes in consumer buying habits as a result of the COVID-19 pandemic.
Gross profit in 2020 decreased $35.9 million, or 3.9%, to $888.3 million from $924.2 million in 2019, driven primarily by a shift in overall sales mix to cigarettes, which have lower margins compared with food/non-food products, and higher LIFO expense, partially offset by $1.9 million of incremental net inventory holding gains.
Gross profit margin was 5.24% of total net sales for 2020 compared to 5.54% in 2019. Remaining gross profit margin(1) decreased to 5.23% for 2020 from 5.53% in 2019. The decline in remaining gross profit margin was driven primarily by the change in the sales mix between cigarettes and food/non-food and a decline in margins within the food/non-food category resulting from a shift in sales mix and lower gross profit margins in certain categories. We expect our gross profit margin to continue to be impacted by both sales mix and lower margins in certain product categories for some period of time as a direct result of the impacts of the COVID-19 pandemic.
Operating expenses in 2020 decreased 4.6%, or $38.0 million, to $793.6 million from $831.6 million in 2019. The decrease was driven primarily by increased productivity and cost savings initiatives, implemented mainly in response to the COVID-19 pandemic. As outlined in our press release on April 14, 2020, we took steps during the second quarter to reduce operating costs to better align them with sales volume trends and to preserve liquidity. We also achieved cost savings through actions to reduce other non-essential costs including travel, meetings and events and other discretionary expenditures. Operating expenses were 4.7% of total net sales for 2020 compared to 5.0% in 2019. Operating expenses were 89.4% of remaining gross profit(1) for 2020, compared to 90.2% of remaining gross profit in 2019.
Net income in 2020 increased 9.5%, or $5.5 million, to $63.2 million from $57.7 million in 2019. Adjusted EBITDA(1) increased $11.5 million, or 6.0%, to $202.2 million in 2020 from $190.7 million in 2019.

Net Sales. Net sales increased by $287.4 million, or 1.7%, to $16,957.9 million in 2020 from $16,670.5 million in 2019. The increase in net sales was driven primarily by strong cigarette sales, including increases in cigarette manufacturers’ prices and growth in cigarette carton sales, partially offset by a decrease in food/non-food sales to existing customers and a net decrease in the number of stores serviced during the year. Sales of both cigarettes and food/non-food products in 2020 were impacted by changes in consumer buying habits as a result of the COVID-19 pandemic.
Net Sales of Cigarettes. Net sales of cigarettes in 2020 increased by $417.8 million, or 3.8%, to $11,310.5 million from $10,892.7 million in 2019. The increase in cigarette sales was driven primarily by a 3.6% increase in the average sales price per carton due to cigarette manufacturers’ price increases and a 0.3% increase in carton sales. Cigarette carton sales increased by 0.2% and 0.7% in the U.S. and Canada, respectively, driven by a 2.3% increase in carton sales to existing customers, partially offset by a net decrease in the number of stores serviced during the year. Cigarette carton sales to existing customers in 2020 outperformed recent downward trends, due primarily to changes in consumer buying behavior as a result of the COVID-19 pandemic.
We believe long-term cigarette consumption will be adversely impacted by rising prices, increases in excise taxes and other legislative actions, diminishing social acceptance, sales through illicit markets and increasing use of alternative nicotine products. We expect cigarette manufacturers will raise prices as carton sales decline in order to maintain or enhance their

overall profitability, thus partially mitigating the effect of the declines to distributors. Historical industry data indicates that convenience retailers have more than offset cigarette profit declines through sales growth in food/non-food products.
Net cigarette sales as a percentage of total net sales were 66.7% in 2020 compared to 65.3% in 2019. The increase in the percentage of net cigarette sales in 2020 was due primarily to changes in consumer buying behavior as a result of the COVID-19 pandemic.
Net Sales of Food/Non-food Products. Net sales of food/non-food products in 2020 decreased $130.4 million, or 2.3%, to $5,647.4 million from $5,777.8 million in 2019.

(1)    Amounts and percentages have been rounded for presentation purposes and might differ from unrounded results.

The decrease in food/non-food sales in 2020 was driven primarily by a decrease in sales to existing customers and a net decrease in the number of stores serviced during the year due primarily to the changes in consumer buying behavior as a result of the COVID-19 pandemic. The largest sales declines were in the food, HB&G and candy categories, partially offset by growth in OTP sales to existing customers. Our HB&G category was also impacted by a decline in sales of alternative nicotine products, which was impacted by both the changes in consumer buying behavior due to the COVID-19 pandemic and the enactment of regulations governing the sale of flavored product categories.
Total net sales of food/non-food products as a percentage of total net sales were 33.3% in 2020 compared to 34.7% in 2019.

Gross Profit. Gross profit represents profit after deducting cost of goods sold from net sales during the period. Inventory holding gains represent incremental revenues whereas vendor incentives, OTP tax refunds and changes in LIFO reserves are components of cost of goods sold. Gross profit in 2020 decreased $35.9 million, or 3.9%, to $888.3 million from $924.2 million in 2019, driven primarily by the overall shift in sales mix to cigarettes, which have lower margins than food/non-food products, and higher LIFO expense, partially offset by $1.9 million of incremental inventory holding gains.
The following table provides the components comprising the change in gross profit as a percentage of net sales for 2020 and 2019 (in millions, except percentages)(1):

(3)    In 2020, $29.8 million and $2.0 million of the cigarette inventory holding gains were attributable to the U.S. and Canada, respectively. In 2019, $21.3 million and $1.7 million of the cigarette inventory holding gains were attributable to the U.S. and Canada, respectively.
(4)    In 2019, all $6.9 million of candy inventory holding gains were attributable to the U.S.
(5)    The increase of $3.1 million in LIFO expense in 2020 was due primarily to an increase in the Producer Price Index (“PPI”) for cigarettes and an increase in inventory levels (see Note 2 - Summary of Significant Accounting Policies to our consolidated financial statements).
(6)    Remaining gross profit is a non-GAAP financial measure, which we provide to segregate the effects of LIFO expense, cigarette inventory holding gains and other items that significantly affect the comparability of gross profit (see reconciliation of remaining gross profit to gross profit in “Non-GAAP Financial Information.”)

Gross profit margin decreased 30 basis points to 5.24% of total net sales during 2020 from 5.54% in 2019. The change in the sales mix between cigarettes and food/non-food contributed to approximately 47% of the gross profit margin decline. In addition, the decrease in gross profit margin for 2020 was driven primarily by an overall decline in food/non-food margins as a result of a shift in sales mix toward lower margin items, such as OTP, due primarily to changes in consumer buying habits as a result of the COVID-19 pandemic. In addition, lower margins within the HB&G category, primarily in alternative nicotine products, also contributed to the decline in overall food/non-food gross profit margin.
Distributors such as Core-Mark may, from time to time, earn higher gross profits on inventory and excise tax stamp quantities on hand at the time manufacturers increase their prices or when states, localities or provinces increase their excise taxes. Such increases are reflected in customer pricing for all subsequent sales, including sales of inventory on hand at the time of the increase. The resulting higher gross profits are referred to as inventory holding gains. In 2020, we had $1.9 million higher inventory holding gains compared to 2019. Cigarette inventory holding gains, which were impacted by the timing and amount of cigarette manufacturers’ price increases, increased $8.8 million in 2020, offset by $6.9 million in inventory holding gains related to a candy price increase in 2019. Historically, significant price increases from candy manufacturers have only occurred every three to four years.
We expect cigarette manufacturers will continue to raise prices as carton sales decline in order to maintain or enhance their overall profitability and the various taxing jurisdictions will raise excise taxes to make up for lost tax dollars related to consumption declines.

LIFO expense was $30.7 million in 2020 compared to $27.6 million in 2019. Since we value our inventory in the U.S. on a LIFO basis, our gross profit can be positively or negatively impacted depending on the relative level of price inflation or
28

Table of Contents
deflation in manufacturer prices as reported in the Bureau of Labor Statistics PPI used to estimate and record our book LIFO expense (see Note 2 - Summary of Significant Accounting Policies to our consolidated financial statements).
Remaining gross profit, a non-GAAP financial measure (see reconciliation of remaining gross profit to gross profit in “Non-GAAP Financial Information”), decreased $34.7 million, or 3.8%, to $887.2 million in 2020 from $921.9 million in 2019. Remaining gross profit margin, a non-GAAP financial measure (see reconciliation of remaining gross profit margin, as well as an explanation of its significance, in “Non-GAAP Financial Information”) decreased to 5.23% in 2020 compared to 5.53% in 2019, driven primarily by the impact of a shift in sales mix towards lower margin cigarettes, a shift in the sales mix within food/non-food towards lower margin categories and lower margins within the HB&G category, primarily in alternative nicotine products.
Cigarette remaining gross profit, a non-GAAP financial measure (see reconciliation of cigarette remaining gross profit to cigarette gross profit in “Non-GAAP Financial Information”), increased $7.3 million, or 3.4%, to $220.9 million in 2020 from $213.6 million for the same period in 2019. The increase in cigarette remaining gross profit was driven primarily by a 3.1% increase in remaining gross profit per carton and a 0.3% increase in cigarette carton sales.
Food/non-food remaining gross profit, a non-GAAP financial measure (see reconciliation of food/non-food remaining gross profit to food/non-food gross profit in “Non-GAAP Financial Information”), decreased $42.0 million or 5.9% to $666.3 million, in 2020 from $708.3 million in 2019. Food/non-food remaining gross profit margin, a non-GAAP financial measure (see reconciliation of food/non-food remaining gross profit margin in “Non-GAAP Financial Information”), decreased to 11.80% in 2020 from 12.26% in 2019, driven primarily by a decrease in sales in certain higher margin categories including food and HB&G, an increase in sales in our lower margin OTP category, and a decline in margin rate, primarily in alternative nicotine products within the HB&G category.
In 2020, our remaining gross profit for food/non-food products was 75.1% of our total remaining gross profit compared to 76.8% for 2019.
Operating Expenses.  Our operating expenses include costs related to warehousing and distribution, SG&A expenses and amortization of intangible assets. In 2020, operating expenses decreased by $38.0 million, or 4.6%, to $793.6 million from $831.6 million in 2019. The decrease was driven primarily by increased productivity and cost savings initiatives implemented mainly in response to the COVID-19 pandemic. As a percentage of total net sales, operating expenses were 4.7% in 2020 compared to 5.0% in 2019. Operating expenses were 89.4% of remaining gross profit, a non-GAAP financial ratio (see reconciliation of operating expenses as a percentage of remaining gross profit, as well as an explanation of its significance, in “Non-GAAP Financial Information”) in 2020, compared to 90.2% of remaining gross profit in 2019. The decrease in operating expenses as a percentage of remaining gross profit was due primarily to operating expense reductions that more than offset the decline in remaining gross profit.
Warehousing and Distribution Expenses.  Warehousing and distribution expenses decreased $24.5 million, or 4.3%, to $541.7 million in 2020 from $566.2 million in 2019. The decrease in warehousing and distribution expenses was due primarily to cost reductions, an increase in productivity and fewer deliveries. Warehousing and distribution expenses were 3.2% of total net sales in 2020 compared to 3.4% of total net sales in 2019. Warehousing and distribution expenses were 61.1% of remaining gross profit, a non-GAAP financial ratio (see reconciliation of operating expenses as a percentage of remaining gross profit, as well as an explanation of its significance, in “Non-GAAP Financial Information”), in 2020, compared to 61.4% of remaining gross profit in 2019.
Selling, General and Administrative (“SG&A”) Expenses.  SG&A expenses decreased $13.2 million, or 5.2%, to $242.2 million in 2020 from $255.4 million in 2019. The reduction in SG&A expenses was due primarily to cost savings initiatives. SG&A expenses for 2019 included $2.3 million of incremental costs related to the relocation of our headquarters. SG&A expenses were 1.4% of total net sales in 2020 compared to 1.5% of total net sales in 2019. SG&A was 27.3% of remaining gross profit, a non-GAAP financial ratio (see reconciliation of operating expenses as a percentage of remaining gross profit, as well as an explanation of its significance, in “Non-GAAP Financial Information”), in 2020, compared to 27.7% of remaining gross profit in 2019.
Amortization Expense.  Amortization expense decreased $0.3 million, or 3.0%, to $9.7 million in 2020 from $10.0 million in 2019.
Interest Expense, Net.  Interest expense, net decreased $3.9 million, or 27.1%, to $10.5 million in 2020 compared to $14.4 million in 2019. Interest expense, net, includes interest, amortization of loan origination costs related to borrowings and facility fees and interest on finance lease obligations. The decrease in net interest expense was due primarily to a decrease in the average borrowing rate and lower average borrowings. Average borrowings in 2020 were $259.5 million with a weighted-average interest rate of 1.8% compared to average borrowings of $303.2 million and a weighted-average interest rate of 3.4% in 2019.

Foreign Currency Transaction Losses, Net.  We recognized a foreign currency transaction loss of $0.9 million in 2020 compared to a loss of $0.8 million in 2019. During times of a strengthening U.S. dollar, we generally record foreign currency losses from our Canadian operations. Conversely, during times of a weakening U.S. dollar, we generally record foreign currency gains.
Income Taxes.  For the year ended December 31, 2020, our effective tax rate was a provision of 24.1% in 2020 compared to a provision of 25.5% in 2019.
Adjusted EBITDA.  Adjusted EBITDA, a non-GAAP financial measure (see reconciliation of Adjusted EBITDA to net income in “Non-GAAP Financial Information”), increased $11.5 million, or 6.0%, to $202.2 million in 2020 from $190.7 million for the same period in 2019. The increase in Adjusted EBITDA was driven primarily by higher operating income in 2020 attained through cost leverage and an increase in inventory holding gains.

Non-GAAP Financial Information
The financial statements in this Annual Report on Form 10-K are prepared in accordance with GAAP. Core-Mark uses certain non-GAAP financial measures including (i) Adjusted EBITDA, (ii) net sales, less excise taxes, (iii) remaining gross profit (including cigarette remaining gross profit and food/non-food remaining gross profit), (iv) remaining gross profit margin (including cigarette remaining gross profit margin and food/non-food remaining gross profit margin), (v) remaining gross profit margin less excise taxes (including cigarette remaining gross profit margin less excise taxes and food/non-food remaining gross profit margin less excise taxes), (vi) cigarette remaining gross profit per carton and (vii) operating expenses (and the components thereof) as a percentage of remaining gross profit. We believe these non-GAAP financial measures provide meaningful supplemental information for investors regarding the performance of our business and facilitate a meaningful period to period evaluation. We also believe these measures allow investors to view results in a manner similar to the method used by our management. Management uses these non-GAAP financial measures in order to have comparable financial results to analyze changes in our underlying business. These non-GAAP measures should be considered as a supplement to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. These measures may be defined differently than other companies and therefore, such measures used by other companies may not be comparable to ours. We strongly encourage investors and stockholders to review our financial statements and publicly filed reports in their entirety and not to rely on any single financial measure. These non-GAAP measures are defined as follows:
(i) Adjusted EBITDA is a measure used by management to measure operating performance. Adjusted EBITDA is equal to net income adding back net interest expense, provision for income taxes, depreciation and amortization, LIFO expense, stock-based compensation expense, net foreign currency transaction gains or losses. See the table below for additional details on the components of Adjusted EBITDA. We believe Adjusted EBITDA is one of the primary measures used externally by our investors, analysts and peers in our industry for purposes of valuation and comparing our results to other companies.
(ii) Net sales less excise taxes is a non-GAAP financial measure which we provide to separate the increase in sales and gross profits due to product sales growth and increases in state, local and provincial excise taxes, which we are responsible for collecting and remitting. Federal excise taxes are levied on the manufacturers who pass the tax on to us as part of the product cost and thus are not a component of our excise taxes. Although increases in cigarette taxes result in higher net sales, our overall gross profit percentage may be reduced.
(iii) Remaining gross profit (including cigarette remaining gross profit and food/non-food remaining gross profit), (iv) remaining gross profit margin (including cigarette remaining gross profit margin and food/non-food remaining gross profit margin), (v) remaining gross profit margin less excise taxes (including cigarette remaining gross profit margin less excise taxes and food/non-food remaining gross profit margin less excise taxes), and (vi) cigarette remaining gross profit per carton, are non-GAAP financial measures, which we provide to segregate the effects of LIFO expense, cigarette holding gains and certain other items that significantly affect the comparability of gross profit.
(vii) Operating expenses (and the components thereof) as a percentage of remaining gross profit is a non-GAAP financial measure, which is used by management to measure operating leverage. Although management also uses operating expenses as a percentage of net sales, this metric may be impacted on a comparable basis by, among other items, excise taxes, changes in manufacturers’ prices (including inflation), and our continuing trend in sales mix shift from cigarettes to higher-margin food/non-food items which have substantially lower selling prices.

(2)    Excise taxes included in our net sales consist of state, local and provincial excise taxes, for which we are the primary obligor and held responsible for remitting to the appropriate tax authorities. Federal excise taxes are levied on the manufacturers who pass the tax on to us as part of the product cost and thus are not a component of our excise taxes.

Liquidity and Capital Resources
Our cash and cash equivalents were $22.8 million and $14.1 million as of December 31, 2020 and 2019, respectively.
Our liquidity requirements arise primarily from our working capital, capital expenditures, debt service requirements for our revolving credit facility (“Credit Facility”), income taxes, repurchases of common stock and dividend payments. We have historically funded our liquidity requirements through our cash flows from operations and external borrowings. For the year ended December 31, 2020, our cash flows provided by operating activities were $147.8 million. Subject to borrowing base limitations, we had $402.4 million of borrowing capacity available under our Credit Facility, excluding the expansion feature of $200.0 million, as of December 31, 2020.
We are potentially exposed to increased credit risk as a result of the COVID-19 crisis. While the vast majority of our customers are convenience retailers that continue to operate as essential businesses, our customers include smaller independent convenience retailers that may face liquidity constraints as a result of reduced store traffic. Our customers also include non-convenience store formats including hotel gift shops, casinos, tobacco shops, schools, airport concessions and other specialty and small format stores that carry convenience products. Some of these customers may have temporarily ceased, or significantly reduced, operations due to government-imposed restrictions, while others have seen a material decline in store traffic.
We have taken actions to help preserve liquidity, including reducing operating costs to better align with the current sales volume trends and closely managing our accounts receivable and capital expenditures.
Given our financial strength coming into the pandemic and ample availability of capital, we expect to be able to maintain adequate liquidity through the current environment, subject to the severity and duration of the COVID-19 pandemic.
Cash Flows from Operating Activities
Our cash flows from operating activities provided net cash of $147.8 million for the year ended December 31, 2020 compared to net cash provided of $89.7 million for the same period in 2019, an increase of $58.1 million. The increase was primarily attributable to changes in working capital, which was a cash use of $16.2 million or $54.0 million lower than the comparative period, and an increase in Adjusted EBITDA (see reconciliation of Adjusted EBITDA to net income in “Non-GAAP Financial Information”).
Our cash flows from operating activities were impacted by the following movements in working capital (in millions):
Year Ended December 31,
20202019Change
Accounts receivable, net$33.1 $(5.2)$38.3

$(16.2)$(70.2)$54.0 

Working capital contributions used cash of $16.2 million for 2020, compared to cash used of $70.2 million for 2019. These contributions for the comparative periods were impacted by, among other items, an increase of inventory levels and cigarette and tobacco taxes payable, partially offset by a decrease of deposits, prepayments and other non-current assets due primarily to the timing of prepayments to cigarette vendors.
Cash Flows from Investing Activities
Our investing activities used net cash of $29.6 million for the year ended December 31, 2020 compared to $31.0 million for the same period in 2019, a decrease in cash use of $1.4 million. Capitalization of software and related development costs were $3.5 million for 2020 compared to $6.0 million for 2019. Additions to property and equipment were $27.2 million for 2020 compared to $22.8 million for the same period in 2019, an increase in cash use of $4.4 million. We expect capital expenditures for 2021 to be approximately $45 million, which will be utilized primarily for maintenance and technology initiatives, as well as upgrades to certain distribution facilities and the relocation of one distribution facility.

Cash Flows from Financing Activities
Our financing activities used net cash of $107.9 million for the year ended December 31, 2020 compared to $71.2 million of net cash used for the same period in 2019, a change of $36.7 million. Net repayments under our Credit Facility during the year ended December 31, 2020, were $66.8 million compared to net borrowings of $4.8 million in 2019. Book overdrafts increased $7.2 million, caused by the level of cash on hand in relation to the timing of accounts payable and vendor prepayments. During the year ended December 31, 2020, we repurchased $10.4 million of our common stock under the 2020 Program, compared to repurchases of $22.0 million in 2019 under the Prior Program.
Our Credit Facility
We have a Credit Facility with a borrowing capacity of $750 million as of December 31, 2020, limited by a borrowing base consisting of eligible accounts receivable and inventories. The Credit Facility expires in February 2026 and has an expansion feature which permits an increase up to an additional $200 million, subject to borrowing base requirements. All obligations under the Credit Facility are secured by first-priority liens on substantially all of our present and future assets. The terms of the Credit Facility permit prepayment without penalty at any time (subject to customary breakage costs with respect to the London Interbank Offer Rate (“LIBOR”) or Canadian Dollar Offer Rate based loans prepaid prior to the end of an interest period). The Credit Facility contains customary affirmative and restrictive covenants.  In addition, the Credit Facility allows for unlimited stock repurchases and dividends as long as we meet certain credit availability percentages and fixed charge coverage ratios. As of December 31, 2020, we were in compliance with all of the covenants under the Credit Facility. See Note 18 - Subsequent Events for changes to our Credit Facility.

See Critical Accounting Policies and Estimates - Claims Liabilities and Insurance Recoverables. See also Note 2 - Summary of Significant Accounting Policies to our consolidated financial statements.
Off-Balance Sheet Arrangements
Letters of Credit. As of December 31, 2020, our standby letters of credit issued under our Credit Facility were $19.5 million and related primarily to casualty insurance. The majority of the standby letters of credit mature in one year. However, in the ordinary course of our business, we will continue to renew or modify the terms of the letters of credit to support business requirements. The liabilities underlying the letters of credit are reflected on our consolidated balance sheets.
Critical Accounting Policies and Estimates
Management’s Discussion and Analysis of our Financial Condition and Results of Operations is based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the U.S. The preparation of our consolidated financial statements requires estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the financial statements and the reported amounts of net sales and expenses during the reporting period. The critical accounting polices used in the preparation of the consolidated financial statements are those that are important both to the presentation of financial condition and results of operations and require significant judgments with regards to estimates. We base our estimates on historical experience and on various assumptions we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. We believe the current assumptions and other considerations used to estimate amounts reflected in our financial statements are appropriate; however, actual results could differ from these estimates.
We consider the allowance for credit losses, claims liabilities and insurance recoverables and valuation of long-lived assets and goodwill to be those estimates which involve a higher degree of judgment and complexity. We believe that the following represent the more critical accounting policies, which are subject to estimates and assumptions used in the preparation of our consolidated financial statements.
Due to the COVID-19 pandemic, there has been increased uncertainty and disruption in the global economy and financial markets. We are not aware of any specific event or circumstance that would require updates to our estimates or judgments or require us to revise the carrying value of our assets or liabilities as of December 31, 2020.
Allowance for Credit Losses
We maintain an allowance for credit losses we estimate will arise from our trade customers’ inability to make required payments. We evaluate the collectability of accounts receivable and determine the appropriate allowance for credit losses based on historical experience, economic conditions and a review of specific customer accounts. In determining the adequacy of allowances for customer receivables, we analyze factors such as the value of any collateral, customer financial statements, historical collection experience, aging of receivables, general economic conditions and other factors. It is possible that the accuracy of the estimation process could be materially affected by different judgments as to the collectability based on information considered and further deterioration of accounts. If circumstances change (i.e., further evidence of material adverse creditworthiness, additional accounts become credit risks, store closures or deterioration in general economic conditions), our estimates of the recoverability of amounts due us could be reduced by a material amount.
The allowance for credit losses at December 31, 2020 and 2019 amounted to 4.3% and 3.5%, respectively, of gross trade accounts receivable.
Credit loss expense associated with our trade customer receivables was $7.6 million and $7.1 million in 2020 and 2019, respectively. As a percentage of net sales, our credit loss expense was less than 0.1% for each of 2020 and 2019.
Claims Liabilities and Insurance Recoverables
We maintain reserves related to workers’ compensation, auto and general liability and health and welfare programs that are principally self-insured. Our workers’ compensation, auto and general liability insurance policies currently include a deductible of $500,000 per occurrence and we maintain excess loss insurance that covers any health and welfare costs in excess of $400,000 per person per year.
Our reserves for workers’ compensation, auto and general insurance liabilities are estimated based on applying an actuarially derived loss development factor to our incurred losses, including losses for claims incurred but not yet reported.
38

Table of Contents
Actuarial projections of losses concerning workers’ compensation, auto and general insurance liabilities are subject to a high degree of variability. Among the causes of this variability are unpredictable external factors affecting future inflation rates, health care costs, litigation trends, legal interpretations, legislative reforms, benefit level changes and claim settlement patterns. Our reserve for health and welfare claims includes an estimate of claims incurred but not yet reported, which is derived primarily from historical experience.
Our claim liabilities and the related recoverables from insurance carriers for estimated claims in excess of the deductible and other insured events are presented in their gross amounts because there is no right of offset. The following is a summary of our net reserves (in millions):

Reserves, net$18.4 $22.8 $41.2 $17.3 $21.7 $39.0 
The increase in these reserves for 2020 was due primarily to new claims in 2020 as well as growth of older claims for our workers compensation, auto and general insurance. A 10% change in our incurred but not reported estimates would increase or decrease the estimated reserves for our workers’ compensation, auto and general insurance, and health and welfare liabilities by $1.4 million, $0.5 million and $0.4 million as of December 31, 2020, respectively.
Valuation of Long-lived Assets
We review our long-lived assets for indicators of impairment whenever events or changes in circumstances indicate that the carrying amounts of such assets may not be recoverable. Long-lived assets consist primarily of land, buildings, delivery, warehouse and office equipment, leasehold improvements and intangible assets with definite useful lives. An impairment of long-lived assets exists when the carrying amount of a long-lived asset, or asset group, exceeds its fair value. Impairment losses are recorded when the carrying amount of the impaired asset is not recoverable. Recoverability is determined by comparing the carrying amount of the asset (or asset group) to the undiscounted cash flows which are expected to be generated from its use. Our estimates of future cash flows are based on historical experience and management’s expectations of relevant customers and markets and other operational factors. These estimates project future cash flows several years into the future and can be affected by factors such as competition, inflation and other economic conditions. We have assessed our asset groups and determined we have six asset groups.  The determination of asset groups primarily considers revenue inter-dependencies related to larger chain customer agreements which are serviced by multiple distribution centers. We did not record impairment losses related to long-lived assets in any of the years ended December 31, 2020 and 2019.
Valuation of Goodwill
Goodwill represents the excess of the purchase consideration of an acquired business over the fair value of the identifiable tangible and intangible assets acquired and liabilities assumed in a business combination. Goodwill is not subject to amortization but must be evaluated for impairment. We test goodwill for impairment annually as of October 1, or whenever events or circumstances indicate that it is more likely than not that the fair value of a reporting unit is below its carrying amount. Our reporting units, which are the U.S. and Canada, also represent our operating segments. Whenever events or circumstances change, we assess the related qualitative factors to determine whether it is necessary to perform the quantitative goodwill impairment test. The tests to evaluate goodwill for impairment are performed at the reporting unit level. In the quantitative impairment test, we compare the fair value of the reporting unit to its carrying value. If the fair value of the reporting unit is less than its carrying value, such excess represents the amount of goodwill impairment for which an impairment loss would be recorded. Determining the fair value of a reporting unit involves the use of significant estimates and
39

Table of Contents
assumptions. The estimated fair value of each reporting unit is based on the discounted cash flow method, which is based on historical and forecasted amounts specific to each reporting unit and considers sales, gross profit, operating profit and cash flows and general economic and market conditions, as well as the impact of planned business and operational strategies and other estimates and assumptions for future growth rates, working capital and capital expenditures. We base our fair value estimates on assumptions we believe to be reasonable at the time, but such assumptions are subject to inherent uncertainty. We did not record any impairment charges related to goodwill during the years ended December 31, 2020 and 2019.
In connection with our annual goodwill impairment testing performed during 2020, the quantitative test indicated that the fair values of the applicable reporting units significantly exceeded their carrying values, and accordingly, no further testing of goodwill was required. However, changes in the judgments and estimates underlying our analysis of goodwill for possible impairment, including expected future cash flows and discount rate, could result in a significantly different estimate of the fair value of the reporting units in the future and could result in impairment of goodwill.
ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Our most significant exposure to market risk comes from changes in short-term interest rates on our variable rate debt. Depending upon the borrowing option chosen, the interest charged is generally based upon the prime rate or LIBOR plus an applicable margin. If interest rates increased 18 basis points (which approximates 10% of the weighted-average interest rate on our average borrowings during the year ended December 31, 2020), our results of operations and cash flows would not be materially affected.
We are exposed to foreign currency risk, primarily through our operations in Canada which conduct business in Canadian dollars. We record gains and losses within our stockholders’ equity due to the translation of our Canadian divisions’ financial statements into U.S. dollars. A 10% unfavorable change in the weighted-average Canadian/U.S. dollar exchange rate for 2020 would have reduced our net sales for 2020 by 1.0% and would not have materially impacted our operating income. Additionally, we incur foreign currency transaction gains and losses related to the level of activity between the U.S. and Canada. In 2020, we realized foreign currency transaction losses of $0.9 million. A 10% unfavorable change in the Canadian/U.S. dollar noon exchange rate on December 31, 2020 would have had an immaterial impact on foreign currency transaction losses for 2020. We did not engage in hedging transactions during 2020, 2019 or 2018.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Stockholders and the Board of Directors of Core-Mark Holding Company, Inc.
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Core-Mark Holding Company, Inc. and subsidiaries (the “Company”) as of December 31, 2020 and 2019, the related consolidated statements of operations, comprehensive income, stockholders’ equity, and cash flows, for each of the three years in the period ended December 31, 2020, and the related notes and the schedule listed in the Index at Item 15 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, in conformity with accounting principles generally accepted in the United States of America.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 1, 2021, expressed an unqualified opinion on the Company’s internal control over financial reporting.
Change in Accounting Principle
As discussed in Note 2 to the financial statements, effective January 1, 2019, the Company adopted FASB Accounting Standards Update 2016-02, Leases, using the modified retrospective approach.
Basis for Opinion
These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial 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 financial 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 financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Other Long-lived Assets – Asset Group Determination – Refer to Note 2 and Note 5 to the consolidated financial statements
Critical Audit Matter Description
An impairment of long-lived assets exists when the carrying amount of a long-lived asset, or asset group, exceeds its fair value. Recoverability is determined by comparing the carrying amount of the asset (or asset group) to the undiscounted cash flows which are expected to be generated from its use. Impairment losses are recorded when the carrying amount of the impaired asset is not recoverable. Management estimates future cash flows based on historical experience and management’s expectations of relevant customers and markets and other operational factors, and these estimated future cash flows can be affected by factors such as competition, inflation, and other economic conditions. Management uses judgment in determining the asset groups. The determination of asset groupings primarily considers revenue inter-dependencies related to larger chain customer agreements which are serviced by multiple distribution centers. The Company has assessed its asset groups and determined in 2020 that it has six asset groups. Although no impairment was recognized, a significant change in asset groups could potentially result in a material impairment charge.

Table of Contents
Given the materiality of the Company’s long-lived assets and the judgment involved in determining asset groups, including the review of assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities, performing audit procedures to evaluate the reasonableness of the determination of asset groups required a high degree of auditor judgment.
How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to the asset group approach used by management included the following, among others:
We tested the effectiveness of the control over management’s review and determination of the asset groups.
We evaluated the reasonableness of management’s asset group determination by assessing the basis for the identification of the lowest level for which identifiable cash flows are largely independent of cash flows of other assets and liabilities and considering the relevant criteria specified by the accounting standards.
We tested management’s revenue dependency analysis, including the inter-dependencies of customers serviced by multiple distribution centers and assessed the reasonableness of the Company’s asset groupings.

CORE-MARK HOLDING COMPANY, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.    Summary of Company Information and Basis of Presentation
Business
Core-Mark Holding Company, Inc. and subsidiaries (referred to herein as the “Company” or “Core-Mark”) is one of the largest marketers of fresh, food and broad-line supply solutions to the convenience retail industry in North America. The Company offers a full range of products, marketing programs and technology solutions to customers in the United States (“U.S.”) and Canada. The Company’s customers include traditional convenience stores, drug stores, mass merchants, grocery stores, liquor stores and other specialty and small format stores that carry convenience products. The Company’s product offering includes cigarettes, other tobacco products (“OTP”), alternative nicotine products, candy, snacks, food, including fresh products, groceries, dairy, bread, beverages, general merchandise and health and beauty care products. The Company operates a network of 32 distribution centers in the U.S. and Canada (excluding two distribution facilities it operates as a third-party logistics provider). Twenty-seven distribution centers are located in the U.S. and five are located in Canada.
Basis of Presentation and Principles of Consolidation
The consolidated financial statements include Core-Mark and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in the consolidated financial statements.
Use of Estimates
The preparation of financial statements in accordance with accounting principles generally accepted in the U.S. (“U.S. GAAP”) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and the 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 considers the allowance for credit losses, claims liabilities and insurance recoverables, valuation of long-lived assets and goodwill and realizability of deferred income taxes to be those estimates which involve a higher degree of judgment and complexity. Actual results could differ from those estimates.
2.    Summary of Significant Accounting Policies
Revenue Recognition
A contract with a customer exists when a customer invoice is generated. The Company considers each item on an invoice as an individual performance obligation. The Company recognizes revenue for each performance obligation when ordered items are delivered, control is transferred, and legal right of ownership passes to the customer. The Company includes fees charged to customers for shipping and handling activities in net sales and the related costs in cost of goods sold upon transfer of control of ordered products to a customer. Revenues are reported net of customer incentives, discounts and returns, including an allowance for estimated returns. The allowance for sales returns is calculated based on the Company’s returns experience, which has historically not been significant. The Company also earns management service fee revenue from operating third-party distribution centers belonging to certain customers. These revenues represented less than 1% of the Company’s total net sales for 2020, 2019 and 2018. Service fee revenue is recognized as earned on a monthly basis in accordance with the terms of the management service fee contracts and is included in net sales on the accompanying consolidated statements of operations. See Note 16 - Segment and Geographic Information for the disaggregation of net sales for each of the two geographic areas in which the Company operates and also by major product category.
Customers Sales Incentives
The Company provides consideration to customers, such as sales allowances or discounts, on a regular basis. Customers’ sales incentives are recorded as a reduction to net sales as each sales incentive is earned by the customer. Customer sales incentives include volume-based rebates that are accounted for as variable consideration. Additionally, the Company may provide allowances for the customers’ commitments to continue using Core-Mark as a supplier. These incentives are known as racking allowances and may be paid at the inception of the customer’s agreement or on a periodic basis. Allowances paid at the inception of the contract are deferred and amortized over the period of the distribution agreement as a reduction to sales.
Vendor Rebates and Promotional Allowances
Periodic payments from vendors in various forms including rebates, promotional allowances and volume discounts, are reflected in the carrying value of the related inventory when earned and in cost of goods sold when the related merchandise is sold. Up-front consideration received from vendors for purchase or other commitments is initially deferred and amortized ratably to cost of goods sold as the performance of the activities specified by the vendor is completed.
49

Table of Contents
Cooperative marketing incentives received from vendors to fund specific programs first offset the costs of the program, and to the extent the consideration exceeds the costs relating to the program, the excess funds are recorded as reductions to cost of goods sold. These amounts are recorded in the period the related promotional or merchandising programs are provided. Certain vendor incentive promotions require the Company to make assumptions and judgments regarding, for example, the likelihood of achieving market share levels or attaining specified levels of purchases. Vendor incentives are at the discretion of the Company’s vendors and can fluctuate due to changes in vendor strategies and market requirements. Vendor rebates and promotional allowances earned totaled $236.5 million, $254.7 million and $237.7 million in 2020, 2019 and 2018, respectively.
Excise Taxes
The Company is responsible for collecting and remitting state, local and provincial excise taxes on cigarettes and other tobacco products and will continue to present excise taxes billed as part of revenue and remittances as part of cost of goods sold. These excise taxes are a significant component of the Company’s net sales and cost of goods sold. In 2020, 2019 and 2018, $3.3 billion, $3.3 billion and $3.5 billion, or 20%, 20% and 21% of the Company’s net sales, and 21%, 21% and 22% of its cost of goods sold, respectively, represented excise taxes. Additionally, federal excise taxes are levied on manufacturers who pass these taxes on to the Company as a portion of the product costs. As a result, federal excise taxes are not a component of the Company’s excise taxes, but are reflected in the cost of inventory until products are sold.
Stock-based Compensation
The Company accounts for stock-based compensation expense related to time-based restricted stock unit (“RSU”) awards and performance-based awards using the grant-date fair value of the awards. For service based awards, the Company recognizes the expense using a straight-line method. For performance based awards, the Company recognizes the expense ratably when achievement of performance conditions becomes probable.
Stock-based compensation expense is included in selling, general and administrative expenses on the consolidated statements of operations. Stock-based compensation expense is calculated based on awards ultimately expected to vest and has been reduced for estimated forfeitures. The Company’s forfeiture experience since inception of its plans has been approximately 5% of the total grants. The historical rate of forfeiture is a component of the basis for predicting the future rate of forfeitures, which are also dependent on the remaining service period related to grants.
Income Taxes
Income taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities, their respective tax bases, and operating loss and tax credit carry-forwards. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred tax assets are reduced by a valuation allowance when the Company does not consider it more likely than not that some portion or all of the deferred tax assets will be realized.
A tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits. The Company has established an estimated liability for income tax exposures that arise and meet the criteria for accrual. The Company prepares and files tax returns based on its interpretation of tax laws and regulations and records estimates based on these judgments and interpretations. In the normal course of business, the Company’s tax returns are subject to examination by various taxing authorities. Such examinations may result in future tax and interest assessments by these taxing authorities. Inherent uncertainties exist in estimates of tax contingencies due to changes in tax law resulting from legislation, regulation and/or as concluded through the various jurisdictions’ tax court systems. The Company classifies interest and penalties related to income taxes as income tax expense. Additionally, the Company releases income tax effects from AOCI as individual items are adjusted (see Note 10 - Income Taxes).

Table of Contents
Earnings Per Share
Basic earnings per share is calculated by dividing net income by the weighted-average number of shares outstanding during each period, excluding unvested RSUs and performance shares. Diluted earnings per share is calculated by dividing net income by weighted-average shares outstanding including common stock equivalents. Common stock equivalents include RSUs and performance-based share awards, if the impact of the individual awards is dilutive, using the treasury stock method (see Note 12 - Earnings Per Share).
Cash, Cash Equivalents and Book Overdrafts
Cash and cash equivalents include cash, money market funds and highly liquid investments with original maturities of three months or less. The Company had book overdrafts of $31.1 million and $23.9 million at December 31, 2020 and 2019, respectively. Book overdrafts consist primarily of outstanding checks in excess of cash on hand in the corresponding bank accounts at the end of the period. The Company’s policy has been to fund these outstanding checks as they clear with cash held on deposit with other financial institutions or with borrowings under the Company’s revolving credit facility.
Accounts Receivable and Allowance for Credit Losses
Accounts receivable consists of trade receivables from customers. The Company evaluates the collectability of accounts receivable and determines the appropriate allowance for credit losses based on historical experience, current economic conditions, and a review of specific customer accounts. Account balances are charged against the allowance when collection efforts have been exhausted and the receivable is deemed uncollectible (see Note 3 - Other Consolidated Balance Sheet Accounts Detail).
Other Receivables
Other receivables consist primarily of amounts due from vendors for promotional and other incentives, which are accrued as earned. The Company evaluates the collectability of amounts due from vendors and determines the appropriate allowance for credit losses based on historical experience, current economic conditions, and a review of specific amounts outstanding (see Note 3 - Other Consolidated Balance Sheet Accounts Detail).
Inventories
Inventories consist of finished goods, including cigarettes and other tobacco products, food and other consumable products held for re-sale and are valued at the lower of cost or net realizable value. In the Company’s U.S. divisions, cost is determined primarily on a last-in, first-out (“LIFO”) basis. The Company uses the link-chain dollar value LIFO method. The inventory price index computation (“IPIC”) is used to calculate LIFO inflation indices, for which the LIFO inflation source is the producer price indices (“PPI”) published by the U.S. Bureau of Labor Statistics (“BLS”). The Company uses the IPIC pooling method, for which LIFO pools are established for each PPI in accordance with current regulations.  When the Company is aware of material price increases or decreases from manufacturers, the Company estimates the PPI for the respective period if it determines the price increase is not fully reflected in the PPI in order to more accurately reflect inflation rates. Under the LIFO method, current costs of goods sold are matched against current sales. Inventories in the Company’s Canadian divisions are valued on a first-in, first-out (“FIFO”) basis, as LIFO is not a permitted inventory valuation method in Canada. Approximately 90% and 89% of the Company’s inventory was valued on a LIFO basis at December 31, 2020 and 2019, respectively. The Company reduces inventory value for spoiled, aged and unrecoverable inventory based on amounts on-hand and historical experience (see Note 4 - Inventories, Net).
Fair Value Measurements
The Company’s financial assets and liabilities are recognized or disclosed at fair value in the financial statements on a recurring basis. The carrying amount of cash equivalents, trade accounts receivable, other receivables, trade accounts payable, cigarette and tobacco taxes payable and other accrued liabilities approximates fair value because of the short maturity of these financial instruments. The carrying amount of the Company’s variable rate debt approximates fair value.
The Company calculates the fair value of certain assets related to acquisitions, investments and impairment evaluations using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value and gives precedence to observable inputs in determining fair value. An instrument’s level within the hierarchy is based on the lowest level of any significant input to the fair value measurement. The following levels were established for each input:
Level 1 - Quoted prices in active markets for identical assets or liabilities.
Level 2 - Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.
51

Table of Contents
Level 3 - Unobservable inputs for the asset or liability, which reflect the Company’s own assumptions about what market participants would assume when pricing the asset or liability.
Business Combinations
The Company accounts for all business combinations using the acquisition method of accounting, which allocates the fair value of the purchase consideration to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values. The excess of the purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. When determining the fair values of assets acquired and liabilities assumed, management makes significant estimates and assumptions. Management may further adjust the acquisition date fair values for a period of up to one year from the date of acquisition. Acquisition-related expenses and transaction costs associated with business combinations are expensed as incurred.
Property and Equipment
Property and equipment are recorded at cost, net of accumulated depreciation and amortization. Depreciation and amortization on new purchases is computed using the straight-line method over the assets’ estimated useful lives. Leasehold improvements are amortized using the straight-line method over the shorter of the estimated useful life of the property or the term of the lease, including available renewal option terms if it is reasonably assured that those options will be exercised. Upon retirement or sale, the cost and related accumulated depreciation of the assets are removed and any related gain or loss is reflected in the consolidated statements of operations. Maintenance and repairs are charged to expense as incurred (see Note 5 - Property and Equipment, Net).
The Company uses the following depreciable lives for its property and equipment:
 Useful Life in Years
Office furniture and equipment
3-10
Delivery equipment
3-10
Warehouse equipment
5-15
Leasehold improvements
3-25
Buildings
15-25
Leases
The Company leases warehouse facilities, trucks, trailers, office equipment and certain sales offices. The Company determines if an arrangement is an operating or finance lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, operating lease liabilities, and long-term operating lease liabilities on our consolidated balance sheets. Finance leases are included in property and equipment, net, accrued liabilities, and long-term debt on our consolidated balance sheets.
Certain of the Company’s real estate leases include one or more options to renew the applicable lease agreement, with the exercise of renewal options at the Company’s sole discretion; the Company generally includes only one real estate lease extension option in the recognition of ROU assets and lease liabilities when it is reasonably certain to be exercised. Certain of the Company’s vehicle leases have residual value guarantees.
Leases with a term of twelve months or less are not recorded on the balance sheet; the Company recognizes lease expenses for such leases on a straight-line basis over the lease term. The majority of the Company’s lease payments are fixed and are incorporated into the ROU lease assets and liabilities for leases with a term greater than twelve months. However, certain vehicle leases have variable payments, such as per-mile charges, which are expensed as incurred. The Company combines lease components and non-lease components across all asset classes for purposes of recognizing lease assets and liabilities. As most of the Company’s leases do not provide an implicit rate, it uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments.
Effective January 1, 2019, the Company adopted Accounting Standards Update No. 2016-02, Leases (Topic 842). As a result, disclosure requirements for reporting periods beginning after January 1, 2019 are presented under Topic 842, while comparative periods prior to January 1, 2019 have not been adjusted and continue to be reported under ASC 840 (see Note 6 - Leases).

Other Long-lived Assets
Intangible assets with definite lives are generally amortized on a straight-line basis over the following lives:
Useful Life in Years
Customer relationships
9-15
Non-competition agreements
1-5
Trade names
1-2
Internally developed and other purchased software
3-7

The Company reviews its long-lived assets for indicators of impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. An impairment of long-lived assets exists when the carrying amount of a long-lived asset, or asset group, exceeds its fair value, and impairment losses are recorded when the carrying amount of the impaired asset is not recoverable. Recoverability is determined by comparing the carrying amount of the asset (or asset group) to the undiscounted cash flows which are expected to be generated from its use, a Level 3 measurement under the fair value hierarchy. The Company has determined that it has six asset groups based on a review of its assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. The determination of asset groups primarily considers revenue inter-dependencies related to larger chain customer agreements which are serviced by multiple distribution centers. During 2020, 2019 and 2018, the Company did not record impairment charges related to long-lived assets (see Note 5 - Property and Equipment, Net and Note 7 - Goodwill and Other Intangible Assets, Net).
Goodwill
Goodwill represents the excess of cost over the fair value of net assets acquired in a business combination. Goodwill is not amortized.
The Company tests goodwill for impairment annually as of October 1 or whenever events or circumstances indicate that it is more likely than not that the fair value of a reporting unit is below its carrying amount. The Company’s reporting units are its U.S. operations and Canadian operations. Whenever events or circumstances change, the Company assesses the related qualitative factors to determine whether it is necessary to perform the quantitative goodwill impairment test. The tests to evaluate goodwill for impairment are performed at the reporting unit level. In the quantitative impairment test, the Company compares the fair value of the reporting unit to its carrying value. If the fair value of the reporting unit is less than its carrying value, such excess represents the amount of goodwill for which an impairment loss would be recorded. Determining the fair value of a reporting unit involves the use of significant estimates and assumptions. The estimated fair value of each reporting unit is based on the discounted cash flow method, which is based on historical and forecasted amounts specific to each reporting unit and considers net sales, gross profit, income from operations and cash flows and general economic and market conditions, as well as the impact of planned business and operational strategies and other estimates and assumptions for future growth rates, working capital and capital expenditures. The Company bases its fair value estimates on assumptions it believes to be reasonable at the time, but such assumptions are subject to inherent uncertainty. Measuring the fair value of reporting units constitutes a Level 3 measurement under the fair value hierarchy. There has been no impairment of goodwill for any periods presented (see Note 7 - Goodwill and Other Intangible Assets, Net).
Computer Software Developed or Obtained for Internal Use
The Company accounts for computer software systems, namely SAP Enterprise Resource Planning modules, the Company’s proprietary Distribution Center Management System (“DCMS”), and software purchased from third-party vendors, using certain criteria under which costs associated with this software are either expensed or capitalized and amortized over periods from three to seven years. During 2020, 2019 and 2018 the Company capitalized $4.4 million, $6.2 million and $2.0 million, respectively, of costs related to software developed or obtained for internal use (see Note 7 - Goodwill and Other Intangible Assets, Net).

Table of Contents
Claims Liabilities and Insurance Recoverables
The Company maintains reserves related to workers’ compensation, auto, general, and health and welfare liability programs that are principally self-insured. The Company currently has a per-claim deductible of $500,000 for its workers’ compensation, auto and general liability self-insurance programs and a per-person annual claim deductible of $400,000 for its health and welfare program. The Company purchases insurance to cover the claims that exceed the deductible up to policy limits. Self-insured reserves are for pending or future claims that fall outside the policy and reserves include an estimate of expected settlements on pending claims and a provision for claims incurred but not reported. Estimates for workers’ compensation, auto and general liability insurance are based on the Company’s assessment of potential liability using an annual actuarial analysis of available information with respect to pending claims, historical experience and current cost trends. Reserves for claims under these programs are included in accrued liabilities (current portion) and claims liabilities, net of current portion on the accompanying consolidated balance sheets.
Claims liabilities and the related recoverables from insurance carriers for estimated claims in excess of the deductible and other insured events are presented in their gross amounts on the accompanying consolidated balance sheets because there is no right of offset. The carrying values of claims liabilities and insurance recoverables are not discounted. Insurance recoverables are included in other receivables, net and other non-current assets, net. The Company had gross liabilities for workers’ compensation, auto, general, and health and welfare liability self-insurance obligations in the amounts of $38.2 million long-term and $22.5 million short-term at December 31, 2020, and $36.1 million long-term and $20.4 million short-term at December 31, 2019. The Company’s liabilities net of insurance recoverables were $22.8 million long-term and $18.4 million short-term at December 31, 2020, and $21.7 million long-term and $17.3 million short-term at December 31, 2019.
Foreign Currency Translation
The operating assets and liabilities of the Company’s Canadian operations, whose functional currency is the Canadian dollar, are translated to U.S. dollars at exchange rates in effect at period-end. Translation gains and losses are recorded in AOCI as a component of stockholders’ equity. Revenue and expenses from Canadian operations are translated using the monthly average exchange rates in effect during the period in which the transactions occur. The Company also recognizes gains or losses on foreign currency exchange transactions between its Canadian and U.S. operations, net of applicable income taxes, in the consolidated statements of operations. The Company currently does not hedge Canadian foreign currency cash flows.
Risks and Concentrations
Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash investments, accounts receivable and other receivables. The Company places its cash and cash equivalents in short-term instruments with high quality financial institutions and limits the amount of credit exposure in any one financial instrument.
A credit review is completed for new customers and ongoing credit evaluations of each customer’s financial condition are performed periodically, with reserves maintained for potential credit losses. Credit limits given to customers are based on a risk assessment of their ability to pay and other factors. Accounts receivable are typically not collateralized, but the Company may require prepayments or other guarantees whenever deemed necessary.
Murphy U.S.A. is the Company’s largest customer and accounted for 13.9%, 12.5% and 11.9% of total net sales in 2020, 2019 and 2018, respectively. No single customer accounted for 10% or more of accounts receivable at December 31, 2020 and 2019.
The Company’s significant suppliers include Altria Group, Inc. (parent company of Philip Morris USA, Inc.) and R.J. Reynolds Tobacco Company. Product purchased from Altria Group, Inc. accounted for approximately 33%, 32% and 33% of total product purchases in 2020, 2019 and 2018, respectively. Product purchases from R.J. Reynolds Tobacco Company were approximately 25%, 22% and 23% of total product purchases in 2020, 2019 and 2018, respectively.
Cigarette sales represented 66.7%, 65.3% and 66.9% of net sales in 2020, 2019 and 2018, respectively, and contributed 25.2%, 23.0% and 26.0% of gross profit in 2020, 2019 and 2018, respectively. Although cigarettes represent a significant portion of the Company’s total net sales, the majority of gross profit is generated from food/non-food products.
Adoption of Accounting Pronouncements
On June 16, 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). The Company adopted this pronouncement on a modified retrospective basis effective January 1, 2020. The new guidance replaces the incurred loss impairment approach with a methodology that incorporates all expected credit loss estimates, resulting in more timely recognition of losses. The adoption of

ASU 2016-13 and all subsequent amendments did not have a material impact on the Company’s consolidated financial statements.
On January 26, 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). The Company adopted this pronouncement on a prospective basis effective January 1, 2020. The new guidance simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. ASU 2017-04 requires goodwill impairment to be measured as the amount by which a reporting unit’s carrying amount exceeds its fair value, not to exceed the carrying amount of its goodwill. Accordingly, the Company has amended its methodology for determining any goodwill impairment calculations. The adoption of ASU 2017-04 did not have a material impact on the Company’s consolidated financial statements.
Recent Accounting Standards or Updates Not Yet Effective
On August 28, 2018, the FASB issued ASU No. 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans -General (Topic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans (“ASU 2018-14”). The new guidance removes disclosures that are no longer considered cost beneficial, clarifies the specific requirements of disclosures and adds disclosure requirements identified as relevant for defined benefit pension and other post-retirement benefit plans. ASU 2018-14 requires retrospective application and is effective for annual periods beginning after December 15, 2020, with early adoption permitted. The Company has determined that ASU 2018-14 will not have a material impact on its consolidated financial statements.
On December 18, 2019 the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”). The new guidance enhances and simplifies various aspects of the income tax accounting guidance, including requirements pertaining to hybrid tax regimes, ownership changes in investments, and interim-period accounting for enacted changes in tax law. ASU 2019-12 is effective for annual periods beginning after December 15, 2020, with early adoption permitted. The Company has determined that ASU 2019-12 will not have a material impact on its consolidated financial statements.

Inventories consist of the following (in millions):

Inventories at FIFO, net of reserves$993.9 $875.6 
Less: LIFO reserve(235.4)(204.7)
Total inventories, net of reserves
$758.5 $670.9 

During periods of rising prices, the LIFO method of costing inventories generally results in higher current costs being charged against income while lower costs are retained in inventories. Conversely, during periods of decreasing prices, the LIFO method of costing inventories generally results in lower current costs being charged against income and higher stated inventories. If the FIFO method had been used for valuing inventories in the U.S., inventories would have been $235.4 million and $204.7 million higher at December 31, 2020 and 2019, respectively. The Company recorded LIFO expense of $30.7 million, $27.6 million and $25.2 million for the years ended December 31, 2020, 2019 and 2018, respectively. The Company had a decrement in certain of its LIFO inventory layers of $20.1 million and $20.3 million in 2020 and 2019, respectively, which had the effect of reducing its LIFO expense by $0.7 million in 2020 and $2.8 million in 2019.

The Company has a revolving credit facility (“Credit Facility”) with a borrowing capacity of $750.0 million as of December 31, 2020, limited by a borrowing base consisting of eligible accounts receivable and inventories. The Credit Facility expires in February 2026 and has an expansion feature which permits an increase of $200.0 million, subject to borrowing base requirements. All obligations under the Credit Facility are secured by first-priority liens on substantially all of the Company’s present and future assets. The terms of the Credit Facility permit prepayment without penalty at any time (subject to customary breakage costs with respect to London Interbank Offer Rate (“LIBOR”) or Canadian Dollar Offer Rate based loans prepaid prior to the end of an interest period). The Credit Facility contains customary affirmative and restrictive covenants.  In addition, the Credit Facility allows for unlimited stock repurchases and dividends, as long as the Company meets certain credit availability percentages and fixed charge coverage ratios. As of December 31, 2020, the Company was in compliance with all of the financial covenants under the Credit Facility. See Note 18 - Subsequent Events for changes to the Company’s Credit Facility.

9.    Commitments and Contingencies
Purchase Commitments
The Company enters into purchase commitments in the ordinary course of business. The Company had purchase obligations of $18.2 million and $19.6 million as of December 31, 2020 and 2019, respectively, related primarily to purchases of compressed natural gas for its trucking fleet, delivery and warehouse equipment, computer software and services and leasehold improvements. Purchase orders for the purchase of inventory and other services are not included in the purchase obligations as of December 31, 2020 and 2019, respectively, because purchase orders represent authorizations to purchase rather than binding agreements.  For purposes of this disclosure, contractual obligations for purchase of goods or services are defined as agreements that are enforceable and legally binding and that specify all significant terms, including: fixed or minimum quantities to be purchased; fixed, minimum or variable price provisions; and the approximate timing of the transaction.  The Company’s purchase orders are based on its current inventory needs and are fulfilled by its suppliers within short time periods.  The Company also enters into contracts for outsourced services; however, the obligations under these contracts are not significant and the contracts generally contain clauses allowing for cancellation without significant penalty.
Letters of Credit
As of December 31, 2020, the Company’s standby letters of credit issued under the Company’s Credit Facility were $19.5 million related primarily to casualty insurance. The majority of the standby letters of credit mature within one year. However, in the ordinary course of business, the Company will continue to renew or modify the terms of the letters of credit to support business requirements. The letters of credit are contingent liabilities, supported by the Company’s line of credit, and are not reflected in the consolidated balance sheets.
Litigation
The Company is subject to certain legal proceedings, claims, investigations and administrative proceedings in the ordinary course of its business. The Company records a provision for a liability when it is probable that the liability has been incurred and the amount of the liability can be reasonably estimated. These provisions, if any, are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular case. In the opinion of management, the outcome of pending litigation is not expected to have a material effect on the Company’s results of operations, financial condition or liquidity.

On October 2, 2019, the United States Judicial Panel on Multidistrict Litigation transferred and consolidated all then-pending personal injury cases against Juul Labs, Inc. (“JLI”) involving the distribution and sale of JUUL products to the Northern District of California (the “JUUL MDL”). Subsequently, on March 11, 2020, the plaintiffs in the JUUL MDL filed a Personal Injury Consolidated Master Complaint against JLI, Philip Morris and various Altria Group entities, JLI co-founders, early JLI investors and board members, certain e-liquid manufacturers, and numerous distributors and retailers of JUUL products, including Core Mark. Consequently, Core-Mark has been added as a defendant in a number of these personal injury suits. The JLI MDL litigation is currently in an early stage, and the personal injury plaintiffs have not made a monetary demand to the defendants. Core-Mark believes that it is entitled to contractual, statutory and/or common law indemnification from JLI for any liability that could result from the JUUL MDL. Core-Mark and JLI are in discussions regarding these indemnification rights.

At each balance sheet date, management assesses whether it is more likely than not that these deferred tax assets would not be realized. As of December 31, 2020, the Company had a valuation allowance of $0.6 million which consisted primarily of net operating loss carry-forwards for certain states. The Company had a valuation allowance of $1.7 million which consisted of $1.0 million of foreign tax credits and $0.7 million of net operating loss carry-forwards for certain states at December 31, 2019, and no valuation allowance at December 31, 2018.
The Company had no unrecognized tax benefits related to federal, state and foreign taxes at December 31, 2020, 2019, and 2018.
The Company files U.S. federal, state and foreign income tax returns in jurisdictions with varying statutes of limitations. The 2017 to 2019 tax years remain subject to examination by federal and state tax authorities. The 2016 tax year is still open for certain state tax authorities. The 2013 to 2019 tax years remain subject to examination by the tax authorities in Canada.

11.    Employee Benefit Plans
Pension Plans
The Company sponsored a qualified defined-benefit pension plan and a post-retirement benefit plan (collectively, “the Pension Plans”). The Pension Plans were frozen on September 30, 1986 and since then there have been no new entrants to the Pension Plans. In September 2016, the Company terminated the qualified defined-benefit pension plan and in December 2017, completed the plan settlement with an annuity transfer to a third-party insurance company.
The Company’s post-retirement benefit plan is not subject to ERISA. As a result, the post-retirement benefit plan is not required to be pre-funded, and accordingly, has no plan assets.
Other post-retirement benefit costs charged to operations are estimated on the basis of annual valuations with the assistance of an independent actuary. Adjustments arising from plan amendments, and changes in assumptions and experience gains and losses, are amortized over the average remaining future service of active employees expected to receive benefits for the post-retirement benefit plan.
The unfunded amount of liability recognized in the balance sheet related to the other post-retirement benefit plan was $2.8 million and $2.4 million, for the years ended December 31, 2020 and 2019, respectively. The net actuarial loss recognized in AOCI was $0.4 million and the net actuarial gain recognized in AOCI was $0.1 million for those same periods, respectively.
Multi-employer Defined Benefit Plan
The Company contributed $0.5 million for the years ended December 31, 2020, 2019, and 2018, to multi-employer defined benefit plans under the terms of a collective-bargaining agreement that covers its union-represented employees.
Savings Plans
The Company maintains defined-contribution plans in the U.S., subject to Section 401(k) of the Internal Revenue Code, and in Canada, subject to the Income Tax Act. For the year ended December 31, 2020, eligible U.S. employees could elect to contribute, on a tax-deferred basis, from 0% to 75% of their compensation to a maximum of $19,500. Eligible U.S. employees over 50 years of age could also contribute an additional $6,500 on a tax-deferred basis. In Canada, employees can elect to contribute up to a maximum of CAD $27,230. Effective January 1, 2021, the maximum contribution available to employees in Canada increased to CAD $27,830. As of December 31, 2020, the Company matches 50% of U.S. and Canada employee contributions up to 6% of base salary for a total maximum company contribution of 3%. In connection with the Company’s cost savings measures during 2020 due to the COVID-19 pandemic, this policy was temporarily halted between April 16, 2020 and September 30, 2020. For the years ended December 31, 2020, 2019 and 2018, the Company made matching payments of $3.1 million, $6.1 million and $5.6 million, respectively.

13.    Stock Incentive Plans
2019 Long-Term Incentive Plan
On May 21, 2019, the Company’s stockholders approved the 2019 Long-Term Incentive Plan (the “2019 LTIP”) which, among other things, replaces the Company’s 2010 Long-Term Incentive Plan (as amended, the “2010 LTIP”) and reserves for awards an aggregate of up to 4,236,959 shares. As of December 31, 2020, the total number of shares available for issuance under the 2019 LTIP was 3,156,745. The 2019 LTIP allows the Company to grant, among other things, time-vesting and performance-vesting restricted stock unit awards. Awards may be made under the 2019 LTIP through May 21, 2029. The Company issues new shares upon vesting of RSUs and performance share awards and they do not have an expiration date.
Prior Long-Term Incentive Plans
The 2007 Long-Term Incentive Plan (“2007 LTIP”) and 2010 LTIP provided for the granting of, among other things, stock appreciation rights, RSUs, other stock-based awards and performance share awards of the Company’s common stock to officers, employees and non-employee directors.

16.    Segment and Geographic Information
The Company identifies its operating segments based primarily on the way the Chief Operating Decision Maker (“CODM”) evaluates performance and makes decisions. The President and Chief Executive Officer of the Company has been identified as the CODM. From the perspective of the CODM, the Company is engaged primarily in the business of distributing packaged consumer products to convenience retail stores in the U.S. and Canada (collectively “North America”), which consists of customers that have similar characteristics. Therefore, the Company has determined that it has two operating segments, U.S. and Canada, that aggregate to one reportable segment. Additionally, the Company presents its segment reporting information based on business operations for each of the two geographic areas in which it operates and also by major product category.

Shareholder Return Plan
In February of 2021, the Company’s Board of Directors approved a new, three-year $375 million shareholder return plan, supporting increased share buy-backs and growth in the Company’s dividend. The new plan replaces the previous $60 million stock repurchase program.
Eleventh Amendment to the Credit Facility
On February 26, 2021, the Company entered into an Eleventh Amendment to its Credit Facility, which primarily extends the maturity date from March 28, 2022 to February 26, 2026. With the Eleventh Amendment, the size and expansion feature of the Credit Facility remain at $750 million and $200 million, respectively. In addition to extending the maturity date of the Credit Facility, among other changes, the Eleventh Amendment increases certain threshold amounts for reporting and notices and increases the size of certain baskets. The Eleventh Amendment also adds certain additional covenant baskets and incorporates customary language regarding LIBOR replacement, defaulting lenders, electronic execution, Bail-in acknowledgement and letters of credit. All obligations under the Credit Facility will continue to be secured by first-priority liens on substantially all of the Company’s present and future assets.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of Core-Mark Holding Company, Inc.

Opinion on Internal Control over Financial Reporting
We have audited the internal control over financial reporting of Core-Mark Holding Company, Inc. and subsidiaries (the “Company”) as of December 31, 2020, 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 Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control – Integrated Framework (2013) issued by COSO.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2020, of the Company and our report dated March 1, 2021, expressed an unqualified opinion on those financial statements.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
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 (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) 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 (3) 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.
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.
