Grainger Shareholders: 

Our customers have some of the toughest jobs imaginable. They are the people 
and businesses who keep schools, hospitals, manufacturing facilities and military 
bases up and running and people safe. They are first responders, maintenance 
managers and contractors who get the call and get the job done. Serving 
these customers is an honor and it’s what fuels Grainger’s nearly 25,000 team 
members every day to work hard, be better and deliver results. 

D.G. Macpherson
Chairman of the Board and  
Chief Executive Officer

Understanding our customers’ unique needs and developing solutions that work 
is how we’ve earned their trust since 1927. No matter the size of the customer 
and across every industry, professionals come to us to solve problems quickly 
and with confidence. These customers value Grainger’s quality products, 
digital solutions, personal relationships and onsite services. Our team members 
operate with an unwavering commitment to deliver a flawless experience for our 
customers. More than three and a half million customers throughout the world experienced this commitment in 
2018 through Grainger’s two different business models that serve them as they wish to be served. 

The first is the high-touch, high-service model designed for customers with complex needs. This model provides 
an integrated offer of high-quality, industrial products backed by sellers, branch associates and customer service 
agents all possessing strong technical knowledge. Grainger businesses in the United States, Canada and 
Mexico as well as Cromwell in the United Kingdom and Fabory in Europe all compete with this model. 

The second is the endless assortment model, which serves customers with less complex needs. This business 
model appeals to customers who want a simple transaction and competitive pricing on all the products that 
serve their business needs. We compete with this model through our MonotaRO business in Japan and our 
Zoro businesses in the United States and Europe.

Grainger’s execution of the strategic imperatives supporting these models made 2018 a strong year. The 
Grainger business in the United States drove significant share gains across large and midsize customers  
as our value proposition continued to resonate. We structurally reset the business in Canada and exited the  
year with a profitable fourth quarter, on an adjusted basis. The endless assortment business continued to  
drive double-digit growth. Across the company, we drove strong operating expense leverage and achieved  
$130 million in cost savings and productivity, which was above our target. We also achieved a 10.3 percent 
reported operating margin and a 12 percent adjusted operating margin—meeting our adjusted operating 
margin target one year earlier than anticipated.1 Other full-year 2018 highlights include:

•  Company sales of $11.2 billion, up 8 percent from 2017. 

•  Volume growth of 8 percent versus 2017. 

•  Reported earnings per share were $13.73, up 37 percent versus 2017. Adjusted earnings per share were  
  $16.70, up 46 percent versus 2017.1 

•  Cash generated from operations of $1.1 billion.

•  Cash returned to shareholders of $741 million in the form of approximately 1.4 million shares repurchased  

for $425 million and $316 million in dividends paid. 

1 See page 84 for a reconciliation of adjusted operating margin and adjusted earnings per share to the most  
  directly comparable GAAP financial measures.

We know that when we combine the best product assortment, customer relationships, digital solutions and 
services with a great experience every time, our value is unbeatable. In 2019, we will continue to strengthen  

that value by: 

•  Powering our digital capabilities with robust product and customer information to build the best solutions  

in our industry;

•  Executing our sales and services plan to create unique value for our customers;

•  Enhancing our industry-leading order transaction process to ensure seamless customer and team  
  member processes; 

•  Improving the customer experience in our Canadian business and across our international portfolio to  
  drive profitable growth; 

•  Adding new products in our endless assortment model to grow our customer base while leveraging  

improved analytics to enhance the customer experience;

•  Achieving our cost reduction targets and

•  Continuing to enhance our team member experience and invest in leader development. 

By accomplishing these priorities, we expect to generate long-term returns for our shareholders, deliver  

a great experience for our customers and team members and serve as a good citizen to our neighbors. 

Our commitment to serving our customers and communities with integrity and helping them succeed  

is core to what we do. Over the last year, we were recognized for how we operate, including a top-10 

placement in Barron’s list of the 100 Most Sustainable U.S. Companies and the top category ranking in 

Fortune’s World’s Most Admired Companies for the sixth consecutive year. Our team members around  

the world are proud to support our customers who keep communities working safely, reliably and  

responsibly today and for years to come.

Item 1: Business 

The Company 

 PART I 

W.W. Grainger, Inc., incorporated in the State of Illinois in 1928, is a broad line, business-to-business distributor of 
maintenance, repair and operating (MRO) products and services. W.W. Grainger, Inc.'s operations are primarily in 
North America, Europe and Japan. In this report, the words “Grainger” or “Company” mean W.W. Grainger, Inc. and 
its subsidiaries, except where the context makes it clear that the reference is only to W.W. Grainger, Inc. itself and not 
its subsidiaries.

Strategy 

In the large and fragmented MRO industry, Grainger holds an advantaged position with its supply chain infrastructure, 
broad in-stock product offering and deep customer relationships. Grainger's purpose is to help businesses keep their 
operations running and their people safe.

The Company competes with two models: the high-touch, high-service model and the endless assortment (single-
channel) model. Competing with these two models allows Grainger to leverage its scale and advantaged supply chain 
to meet the changing needs of its customers. Grainger’s high-touch, high-service model serves customers with complex 
needs in North America and Europe. The endless assortment model is focused on customers with less-complex needs 
and includes the Zoro Tools, Inc. (Zoro) brand in the U.S. and MonotaRO Co., Ltd. (MonotaRO) in Japan.

MRO Industry

The global MRO market is approximately $608 billion, and the estimated market size where Grainger has operations 
is $284 billion. The most attractive geographies for Grainger are those with high GDP per capita and a developed 
infrastructure. Grainger’s strategy is concentrated in North America, Europe and Japan. Each of these core markets 
is large and the competition is highly fragmented. In total, Grainger has about 4 percent share within its addressable 
market with ample opportunity for growth. 

Grainger’s two reportable segments are the U.S. and Canada, and they are described further below.  Other businesses 
include the endless assortment businesses, Zoro in the U.S. and MonotaRO in Japan, and smaller businesses in 
Europe, Asia and Mexico. For further segment and financial information, see “Item 7: Management’s Discussion and 
Analysis of Financial Condition and Results of Operations” and Note 17 to the Consolidated Financial Statements 
(Financial Statements).

Customers and Products 

Grainger serves more than 3.5 million customers worldwide through its DCs, eCommerce platform, contact centers, 
branches and sales and service representatives. These customers represent a broad collection of industries including 
government, manufacturing, transportation, commercial and contractors (see Note 2 to the Financial Statements). 

Grainger offers a broad selection of products to its customers including material-handling equipment, safety and security 
supplies,  lighting  and  electrical  products,  power  and  hand  tools,  pumps  and  plumbing  supplies,  cleaning  and 
maintenance supplies and metalworking tools. Products are regularly added and deleted from Grainger's product lines 
on the basis of customer demand, market research, suppliers' recommendations, sales volumes and other factors. 
No one product category comprises more than 18% of global sales.

United States 

The U.S. business offers a broad selection of MRO products and services through its eCommerce platform, catalogs, 
branches and sales and service representatives. A combination of product breadth, local availability, speed of delivery, 
detailed product information and competitively priced products and services is provided by this business. 

The U.S. business purchases products for sale from approximately 3,000 suppliers, most of which are manufacturers. 
No single supplier comprised more than 5% of total purchases and no significant barriers thus far exist with respect 
to sources of supply. The majority of products sold by the U.S. business are nationally branded products. In addition, 
approximately 21% of 2018 sales were private label MRO items bearing Grainger’s registered trademarks, including 
DAYTON®, SPEEDAIRE®, AIR HANDLER®, TOUGH GUY®, WESTWARD®, CONDOR® and LUMAPRO®. Grainger 
has taken steps to protect these trademarks against infringement and believes that they will remain available for future 
use in its business.

The U.S. business operates and fulfills orders nationally through a network of DCs, branches and contact centers. 
Customers range from small and mid-sized businesses to large corporations, government entities and other institutions 
within many industries (see Note 2 to the Financial Statements). Sales in 2018 were made to more than 1 million
customers and no single end customer accounted for more than 1% of total sales. The U.S. business also exports to 
various countries.

Macro trends and technology drive the way Grainger's U.S. customers behave. Customers want highly tailored solutions 
with real-time access to information and just-in-time delivery of products and services. Demands for transparency are 
also increasing as access to information expands. These changes are reflected in how customers do business in the 
U.S. as demonstrated in the following tables for the 2018 line mix:

U.S. customers continue to migrate to web and electronic platforms such as EDI, eProcurement and KeepStock®. 
Through  Grainger.com  and  other  branded  websites,  customers  have  access  to  more  than  2.9  million  products. 
Grainger.com  provides  real-time  price  and  product  availability,  detailed  product  information  and  features  such  as 
product search and compare capabilities. For customers with sophisticated electronic purchasing platforms, the U.S. 
business utilizes technology that allows these systems to communicate directly with Grainger.com. 

The U.S. business has an outside and inside sales force to help customers select the right products for their needs 
and reduce costs by utilizing Grainger as a consistent source of supply. 

Inventory management is another area where the U.S. business helps customers be more productive. KeepStock®  
is a comprehensive program that includes vendor-managed inventory, customer-managed inventory and onsite vending 
machines. 

DCs in the U.S. business range in size from approximately 45,000 square feet to 1.3 million square feet, the largest 
of which can accommodate more than 500,000 in-stock products.  Automation in the DCs allows Grainger to ship most 
orders complete with next-day delivery and replenish branches that provide same-day availability. 

Branches in the U.S. business serve the immediate needs of customers in their local markets by allowing them to 
directly pick up items. Branches also support local KeepStock® operations and allow customers to leverage branch 
staff for their technical product expertise and search-and-select support. 

Grainger's contact center network in the U.S. business on average handles about 73,000 customer interactions per 
day including approximately 20,000 orders via phone, e-mail and chat. 

Canada 

Acklands – Grainger Inc. and its subsidiaries (the Canada business) provide a combination of product breadth, local 
availability, speed of delivery, detailed product information and competitively priced products and services.  The Canada 
business serves customers through branches, DCs and sales and service representatives. Customers have access 
to more than 194,000 stocked products through a comprehensive catalog and website.

Other businesses 
Other businesses is comprised of the endless assortment businesses, Zoro in the U.S. and MonotaRO in Japan, and 
smaller high-touch, high-service businesses in Europe, Asia and Mexico. 

Zoro
Zoro is an online MRO distributor, primarily serving U.S. customers through its website, Zoro.com. Zoro, with sales of 
more than $500 million in 2018, offers a broad selection of more than 2 million products to its customers. Zoro has no 
branches or sales force, and customer orders are fulfilled through the U.S. business supply chain and third parties. 

MonotaRO
Grainger operates in Japan and other Asian countries primarily through its majority interest in MonotaRO. MonotaRO 
had nearly $1 billion in revenue in 2018 and provides customers with access to approximately 20 million MRO products 
primarily through its websites and catalogs. A majority of orders are conducted through MonotaRO.com and fulfilled 
from its DCs and third parties.  

7

Seasonality 
Grainger’s business in general is not seasonal, however, there are some products that typically sell more often during 
the winter or summer seasons. In any given month, unusual weather patterns, that is, unusually hot or cold weather, 
could positively or negatively impact the sales volumes of these products.

Competition 
Grainger faces competition in each market from manufacturers (including some of its own suppliers) that sell directly 
to certain segments of the market, to wholesale distributors, catalog houses, retail enterprises and internet-based 
businesses. Grainger differentiates itself by providing local product availability, a broad product line, sales and service 
representatives, competitive pricing, catalogs (which include product descriptions and, in certain cases, extensive 
technical and application data) and electronic and eCommerce technology. Grainger also offers other services, such 
as inventory management. Grainger has several large competitors and continues to be highly competitive against the 
predominant number of small local and regional competitors.

Employees
As of December 31, 2018, Grainger had approximately 24,600 employees, of whom approximately 23,100 were full-
time and 1,500 were part-time or temporary. Grainger has never had a major work stoppage and considers employee 
relations to be good.

Website Access to Company Reports 
Grainger makes available free of charge, through its website, www.grainger.com/investor, its Annual Report on Form 
10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, proxy statements and amendments to those reports

Item 1A: Risk Factors

The following is a discussion of significant risk factors relevant to Grainger’s business that could adversely affect its 
financial condition, results of operations and cash flows. The risk factors discussed in this section should be considered 
together with information included elsewhere in this Annual Report on Form 10-K and should not be considered the 
only risks to which the Company is exposed.

Weakness in the economy, market trends and other conditions affecting the profitability and financial stability 
of Grainger’s customers could negatively impact Grainger’s sales growth and results of operations.

Economic, political, and industry trends affect Grainger’s business environments. Grainger serves several industries 
and markets in which the demand for its products and services is sensitive to the production activity, capital spending 
and demand for products and services of Grainger’s customers. Many of these customers operate in markets that are 
subject to cyclical fluctuations resulting from market uncertainty, trade and tariff policies, costs of goods sold, currency 
exchange rates, central bank interest rate changes, foreign competition, offshoring of production, oil and natural gas 
prices, geopolitical developments, labor shortages, inflation, deflation, and a variety of other factors beyond Grainger’s 
control. Any of these factors could cause customers to idle or close facilities, delay purchases, reduce production 
levels, or experience reductions in the demand for their own products or services.

Any of these events could also reduce the volume of products and services these customers purchase from Grainger 
or impair the ability of Grainger’s customers to make full and timely payments, and could cause increased pressure 
on Grainger’s selling prices and terms of sale. Accordingly, a significant or prolonged slowdown in activity in the U.S., 
Canada or any other major world economy, or a segment of any such economy, could negatively impact Grainger’s 
sales growth and results of operations.

The facilities maintenance industry is highly competitive, and changes in competition could result in decreased 
demand for Grainger’s products and services.

Grainger competes in a variety of ways, including product assortment and availability, services offered to customers, 
pricing, purchasing convenience, and the overall experience Grainger offers.  This includes the ease of use of Grainger’s 
high-touch high-service operations (branches and digital platforms) and delivery of products.

There are several large competitors in the industry, although most of the market is served by small local and regional 
competitors.  Grainger  faces  competition  in  all  markets  it  serves,  from  manufacturers  (including  some  of  its  own 
suppliers) that sell directly to certain segments of the market, wholesale distributors, catalog houses, retail enterprises 
and online businesses that compete with price transparency.  

To remain competitive, the Company must be willing and able to respond to market pressures. These pressures, and 
the implementation, timing and results of Grainger’s strategic pricing and other responses, could have a material effect 
on Grainger’s sales and profitability. If the Company is unable to grow sales or reduce costs, among other actions, to 
wholly or partially offset the effect on profitability of its pricing actions, the Company’s results of operations and financial 
condition may be adversely affected.

Moreover, Grainger expects technological advancements and the increased use of eCommerce solutions within the 
industry to continue to evolve at a rapid pace. As a result, Grainger’s ability to effectively compete requires Grainger 
to respond and adapt to new industry trends and developments, and implement new technology and innovations that 
may result in unexpected costs or may take longer than expected.

Volatility in commodity prices may adversely affect gross margins.

Some  of  Grainger’s  products  contain  significant  amounts  of  commodity-priced  materials,  such  as  steel,  copper, 
petroleum  derivatives,  or  rare  earth  minerals,  and  are  subject  to  price  changes  based  upon  fluctuations  in  the 
commodities market. Fluctuations in the price of fuel could affect transportation costs. Grainger’s ability to pass on 
such increases in costs in a timely manner depends on market conditions. The inability to pass along cost increases 
could result in lower gross margins. In addition, higher prices could impact demand for these products, resulting in 
lower sales volumes.

9

Unexpected product shortages, tariffs, and risks associated with Grainger’s suppliers could negatively impact 
customer relationships or result in an adverse impact on results of operations.

Grainger’s competitive strengths include product selection and availability. Products are purchased from approximately 
5,000 suppliers located in various countries around the world, not one of which accounted for more than 5% of total 
purchases.

Historically, no significant difficulty has been encountered with respect to sources of supply; however, disruptions could 
occur due to factors beyond Grainger’s control, including economic downturns, geopolitical unrest, new tariffs or tariff 
increases, trade issues and policies, labor problems experienced by Grainger’s suppliers, transportation availability 
and cost, inflation and other factors, any of which could adversely affect a supplier’s ability to manufacture or deliver 
products or could result in an increase in Grainger’s product costs.

Further, Grainger sources products from Asia and other areas of the world.  This increases the risk of supply disruption 
due to the additional lead time required and distances involved.  

If Grainger was to experience difficulty in obtaining products, there could be a short-term adverse effect on results of 
operations and a longer-term adverse effect on customer relationships and Grainger’s reputation. In addition, Grainger 
has strategic relationships with a number of vendors. In the event Grainger was unable to maintain those relations, 
there might be a loss of competitive pricing advantages which could, in turn, adversely affect results of operations.

Changes in customer base or product mix could cause changes in Grainger’s gross margin or affect Grainger’s 
competitive position.

From time to time, Grainger experiences changes in customer base and product mix that affect gross margin. Changes 
in customer base and product mix result primarily from business acquisitions, changes in customer demand, customer 
acquisitions, selling and marketing activities and competition. There can be no assurance that Grainger will be able 
to maintain historical gross margins in the future.  

Additionally, as customer base and product mix change over time, Grainger must identify new products, product lines 
and services that respond to industry trends and customer needs. The inability to introduce new products and effectively 
integrate them into Grainger’s existing product mix could have a negative impact on future sales growth and Grainger’s 
competitive position.  

Disruptions in Grainger’s supply chain could result in an adverse impact on results of operations.

The occurrence of one or more natural disasters such as earthquakes, storms, hurricanes, floods, fires, droughts, 
tornados and other extreme weather; geopolitical events, such as war, civil unrest or terrorist attacks in a country in 
which Grainger operates or in which its suppliers are located; and the imposition of measures that create barriers to 
or increase the costs associated with international trade could result in disruption of Grainger’s logistics or supply chain 
network. Any such disruption could cause one or more of Grainger’s distribution centers or branches to become non-
operational, adversely affect Grainger’s ability to obtain or deliver inventory in a timely manner, impair Grainger’s ability 
to  meet  customer  demand  for  products,  result  in  lost  sales,  additional  costs,  or  penalties,  or  damage  Grainger’s 
reputation. Grainger’s ability to provide same-day shipping and next-day delivery is an integral component of Grainger’s 
business strategy and any such disruption could adversely impact results of operations and financial performance. 

Interruptions  in  the  proper  functioning  of  information  systems  could  disrupt  operations  and  cause 
unanticipated increases in costs and/or decreases in revenues.

The proper functioning of Grainger’s information systems is critical to the successful operation of its business. Grainger 
continues to invest in software, hardware and network infrastructures in order to effectively manage its information 
systems. Although Grainger’s information systems are protected with robust backup and security systems, including 
physical  and  software  safeguards  and  remote  processing  capabilities,  information  systems  are  still  vulnerable  to 
damage or interruption from natural disasters, power losses, telecommunication failures, user error, third party actions 
such as malicious computer programs, denial-of-service attacks and cybersecurity breaches, and other problems. 

If Grainger’s systems are damaged, breached or cease to function properly Grainger may have to make a significant 
investment to repair or replace them and may suffer interruptions in its business operations in the interim. If critical 
information systems fail or otherwise become unavailable, among other things, Grainger’s ability to process orders, 

10

maintain proper levels of inventories, collect accounts receivable, and disburse funds could be adversely affected. Any 
such interruption of Grainger’s information systems could have a material adverse effect on its business or results of 
operations.

Cybersecurity  incidents,  including  breaches  of  information  systems  security,  could  damage  Grainger’s 
reputation, disrupt operations, increase costs and/or decrease revenues.

Through Grainger’s sales and eCommerce channels, Grainger collects and stores personally identifiable, confidential, 
proprietary and other information from customers so that they may, among other things, purchase products or services, 
enroll in promotional programs, register on Grainger’s websites or otherwise communicate or interact with the Company. 
Moreover, Grainger’s operations routinely involve receiving, storing, processing and transmitting sensitive information 
pertaining to its business, customers, suppliers and employees, and other sensitive matters.

Cyber threats are rapidly evolving and those threats and the means for obtaining access to information in digital and 
other storage media are becoming increasingly sophisticated.  Each year, cyber-attackers make numerous attempts 
to access the information stored in our information systems. 

Moreover, from time to time, Grainger may share information with vendors and other third parties that assist with certain 
aspects  of  the  business.  While  Grainger  requires  assurances  that  these  vendors  and  other  parties  will  protect 
confidential information, there is a risk that the confidentiality of data held or accessed by them may be compromised. 
If  successful,  those  attempting  to  penetrate  Grainger’s  or  its  vendors’  information  systems  may  misappropriate 
personally identifiable, credit card, confidential, proprietary or other sensitive customer, supplier, employee or business 
information, or cause systems disruption.  

In addition, a Grainger employee, contractor or other third party with whom Grainger does business may attempt to 
circumvent  security  measures  in  order  to  obtain  such  information  or  inadvertently  cause  a  breach  involving  such 
information.  Further, Grainger’s systems are integrated with customer systems in certain cases, and a breach of the 
Company’s information systems could be used to gain illicit access to customer systems and information.  

While Grainger has instituted safeguards for the protection of such information, because techniques used to obtain 
unauthorized access or to sabotage systems change frequently and generally are not recognized until they are launched 
against a target, Grainger may be unable to anticipate these techniques or implement adequate preventative measures. 
Any breach of Grainger’s security measures or any breach, error or malfeasance of those of its third party service 
providers could cause Grainger to incur significant costs to protect any customers, suppliers, employees, and other 
parties  whose  personal  data  is  compromised  and  to  make  changes  to  its  information  systems  and  administrative 
processes to address security issues. Loss of customer, supplier, employee or other business information could disrupt 
operations,  damage  Grainger’s  reputation  and  expose  Grainger  to  claims  from  customers,  suppliers,  financial 
institutions, regulators, payment card associations, employees and others, any of which could have a material adverse 
effect on Grainger, its financial condition and results of operations. 

In the past, Grainger has experienced certain cybersecurity incidents. In each instance, Grainger provided notifications 
and adopted remedial measures. While these incidents have not been deemed to be material to Grainger, there can 
be no assurance that a future breach or incident would not be material to Grainger's operations and financial condition.

Grainger’s ability to adequately protect its intellectual property or successfully defend against infringement 
claims by others may have an adverse impact on operations.

Grainger’s business relies on the use, validity and continued protection of certain proprietary information and intellectual 
property,  which  includes  current  and  future  patents,  trade  secrets,  trademarks,  service  marks,  copyrights  and 
confidentiality agreements as well as license and sublicense agreements to use intellectual property owned by affiliated 
entities or third parties. Unauthorized use of Grainger’s intellectual property by others could result in harm to various 
aspects of the business and may result in costly and protracted litigation in order to protect its rights. In addition, 
Grainger may be subject to claims that it has infringed on the intellectual property rights of others, which could subject 
Grainger to liability, require Grainger to obtain licenses to use those rights at significant cost or otherwise cause Grainger 
to modify its operations.

11

Fluctuations in foreign currency could have an effect on reported results of operations.

Grainger’s exposure to fluctuations in foreign currency rates results primarily from the translation exposure associated 
with the preparation of the Consolidated Financial Statements, as well as from transaction exposure associated with 
transactions in currencies other than an entity’s functional currency. While the Consolidated Financial Statements are 
reported in U.S. dollars, the financial statements of Grainger’s subsidiaries outside the U.S. are prepared using the 
local currency as the functional currency and translated into U.S. dollars. In addition, Grainger is exposed to foreign 
currency exchange rate risk with respect to the U.S. dollar relative to the local currencies of Grainger’s international 
subsidiaries,  primarily  the  Canadian  dollar,  euro,  pound  sterling,  Mexican  peso,  renminbi  and  yen,  arising  from 
transactions in the normal course of business, such as sales and loans to wholly owned subsidiaries, sales to customers, 
purchases from suppliers, and bank loans and lines of credit denominated in foreign currencies. Grainger also has 
foreign currency exposure to the extent receipts and expenditures are not denominated in the subsidiary’s functional 
currency and that could have an impact on sales, costs and cash flows. These fluctuations in foreign currency exchange 
rates could affect Grainger’s results of operations and impact reported net sales and net earnings.

Acquisitions, partnerships, joint ventures and other business combination transactions involve a number of 
inherent risks, any of which could result in the benefits anticipated not being realized and could have an 
adverse effect on results of operations.

Acquisitions, partnerships, joint ventures and other business combination transactions, both foreign and domestic, 
involve various inherent risks, such as uncertainties in assessing value, strengths, weaknesses, liabilities and potential 
profitability.  There  is  also  risk  relating  to  Grainger’s  ability  to  achieve  identified  operating  and  financial  synergies 
anticipated  to  result  from  the  transactions.  Additionally,  problems  could  arise  from  the  integration  of  acquired 
businesses, including unanticipated changes in the business or industry or general economic or political conditions 
that affect the assumptions underlying the acquisition. Any one or more of these factors could cause Grainger to not 
realize the benefits anticipated or have a negative impact on the fair value of the reporting units. Accordingly, goodwill 
and intangible assets recorded as a result of acquisitions could, and have in the past, become impaired.

In order to compete, Grainger must attract, retain and motivate key employees, and the failure to do so could 
have an adverse effect on results of operations.

In order to compete and have continued growth, Grainger must attract, retain and motivate executives and other key 
employees, including those in managerial, technical, sales, marketing and support positions. Grainger competes to 
hire employees and then must train them and develop their skills and competencies. Grainger’s results of operations 
could be adversely affected by increased costs due to increased competition for employees, higher employee turnover 
or increased employee benefit costs.

Grainger’s continued success is substantially dependent on positive perceptions of Grainger’s reputation.

One of the reasons why customers choose to do business with Grainger and why employees choose Grainger as a 
place of employment is the reputation that Grainger has built over many years. To be successful in the future, Grainger 
must continue to preserve, grow and leverage the value of Grainger’s brand. Reputational value is based in large part 
on perceptions of subjective qualities. Even an isolated incident, or the aggregate effect of individually insignificant 
incidents, can erode trust and confidence, particularly if they result in adverse publicity, governmental investigations 
or litigation, and as a result, could tarnish Grainger’s brand and lead to adverse effects on Grainger’s business.

Grainger is subject to various domestic and foreign laws, regulations and standards. Failure to comply or 
unforeseen  developments  in  related  contingencies  such  as  litigation  could  adversely  affect  Grainger’s 
financial condition, results of operations and cash flows.

Grainger’s business is subject to legislative, legal, and regulatory risks and conditions specific to the countries in which 
it operates. In addition to Grainger’s U.S. operations, which in 2018 generated approximately 72% of its consolidated 
net sales, Grainger operates its business principally through wholly-owned subsidiaries in Canada, China, Germany, 
Mexico, the Netherlands, and the United Kingdom, and its majority-owned subsidiary in Japan.

The wide array of laws, regulations and standards in each domestic and foreign jurisdiction where Grainger operates, 
include, but are not limited to: advertising and marketing regulations, anti-bribery and corruption laws, anti-competition 
regulations, data protection (including, because Grainger accepts credit cards, the Payment Card Industry Data Security 
Standard), data privacy (including in the U.S. and the European Union, which has traditionally imposed strict obligations 

12

under data privacy laws and regulations that vary from country to country) and cybersecurity requirements (including 
protection of information and incident responses), environmental protection laws, foreign exchange controls and cash 
repatriation restrictions, government business regulations applicable to Grainger as a government contractor selling 
to federal, state and local government entities, health and safety laws, import and export requirements, intellectual 
property  laws,  labor  laws  (including  federal  and  state  wage  and  hour  laws),  product  compliance  laws,  supplier 
regulations regarding the sources of supplies or products, tax laws (including as to U.S. taxes on foreign subsidiaries), 
unclaimed  property  laws  and  laws,  regulations  and  standards  applicable  to  other  commercial  matters.  Moreover, 
Grainger is also subject to audits and inquiries in the normal course of business.

Failure to comply with any of these laws, regulations and standards could result in civil, criminal, monetary and non-
monetary penalties and/or loss of authorization to participate in, or exclusion from, government contracting, as well 
as  potential  damage  to  the  Company’s  reputation.    Changes  in  these  laws,  regulations  and  standards,  or  in  their 
interpretation,  could  increase  the  cost  of  doing  business,  including,  among  other  factors,  as  a  result  of  increased 
investments  in  technology  and  the  development  of  new  operational  processes.  Furthermore,  while  Grainger  has 
implemented policies and procedures designed to facilitate compliance with these laws, regulations and standards, 
there can be no assurance that employees, contractors, suppliers, vendors, or other third parties will not violate such 
laws, regulations and standards or Grainger’s policies. Any such failure to comply or violation could individually or in 
the aggregate materially adversely affect Grainger’s financial condition, results of operations and cash flows.

In addition, Grainger’s business and results of operations in the UK may be negatively affected by changes in trade 
policies, or changes in labor, immigration, tax or other laws, resulting from the UK’s anticipated exit from the European 
Union.

Grainger also is, and from time to time may become, party to a number of legal proceedings incidental to Grainger’s 
business involving alleged damages or injuries arising out of the use of Grainger’s products and services or violations 
of these laws, regulations or standards. The defense of these proceedings may require significant expenses and divert 
management’s time and attention, and Grainger may be required to pay damages that could individually or in the 
aggregate  materially  adversely  affect  its  financial  condition,  results  of  operations  and  cash  flows.  In  addition,  any 
insurance  or  indemnification  rights  that  Grainger  may  have  with  respect  to  such  matters  may  be  insufficient  or 
unavailable to protect the Company against potential loss exposures.

Tax changes could affect Grainger’s effective tax rate and future profitability.

Grainger’s future results could be adversely affected by changes in the effective tax rate as a result of changes in 
Grainger’s overall profitability and changes in the mix of earnings in countries with differing statutory tax rates, changes 
in  tax  legislation,  the  results  of  the  examination  of  previously  filed  tax  returns  and  continuing  assessment  of  the 
Company’s tax exposures.

Grainger’s common stock may be subject to volatility or price declines. 

The trading price of Grainger’s common stock is subject to broad and unpredictable fluctuation due to changes in 
economic, political and market conditions, the operating results of Grainger and its competitors, changes in expectations 
as to Grainger’s future financial or operating performance, including estimates by securities analysts and investors, 
changes in capital structure, stock repurchase programs or dividend policies, and a number of other factors, including 
those discussed in this Item 1A. These factors, many which are outside of Grainger’s control, could cause stock price 
volatility or Grainger’s stock price to decline.

The items discussed below are considered to materially affect the comparability of the information reflected in the 
selected financial data. For further information see “Part II, Item 7: Management's Discussion and Analysis of Financial 
Condition and Results of Operations” of this report, which is incorporated herein by reference.

Net earnings for 2018 included a net expense of $170 million primarily consisting of a $133 million net non-cash charge 
related to the Cromwell goodwill and trade name impairment in other businesses and a net charge of $37 million related 
to restructuring primarily consisting of asset impairment charges in Canada and other related charges, net of gains 
from the sales of branches in the U.S., Canada and corporate offices. 

Net earnings for 2017 included a net expense of $84 million primarily consisting of a net charge of $102 million related 
to restructuring and other charges primarily consisting of branch closures in the U.S. and Canada businesses, net of 
gains on sale of branch real estate in the U.S., the consolidation of the contact center network in the U.S. and the 
wind-down of operations in Colombia, which is part of other businesses. This was partially offset by the net benefit of 
$15 million related to U.S. tax legislation and other discrete tax items.

Net earnings for 2016 included a net expense of $105 million primarily related to restructuring actions in the U.S. and 
Canada, goodwill and intangible impairments, contingencies and a net tax benefit.

Net earnings for 2015 included a net charge of $30 million primarily composed of a $25 million net charge related to 
the reorganization in the U.S. and Canada businesses and a $5 million charge for restructuring in other businesses. 

Net earnings for 2014 included a net charge of $56 million primarily composed of a $28 million charge related to closing 
of the business in Brazil, a $10 million charge due to a retirement plan transition in Europe, a $10 million charge related 
to restructuring of the business in Europe and an $8 million charge related to a goodwill impairment charge in other 
businesses. 

Grainger completed several acquisitions in the years 2014 and 2015, all of which were immaterial individually and in

dates.

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

General

W.W. Grainger, Inc. (Grainger) is a broad line, business-to-business distributor of maintenance, repair and operating 
(MRO) products and services with operations primarily in North America, Europe and Japan. More than 3.5 million 
customers worldwide rely on Grainger for products such as safety, gloves, ladders, motors and janitorial supplies, 
along with services like inventory management and technical support. These customers represent a broad collection 
of industries (see Note 2 to the Consolidated Financial Statements (Financial Statements)). They place orders online, 
on mobile devices, through sales representatives, over the phone and at local branches. Approximately 5,000 suppliers 
provide  Grainger  with  about  1.7  million  products  stocked  in  Grainger's  distribution  centers  (DCs)  and  branches 
worldwide. 

Grainger’s two reportable segments are the U.S. and Canada (Acklands - Grainger, Inc. and its subsidiaries). These 
reportable segments reflect the results of the Company's high-touch, high-service businesses in those geographies. 
Other businesses include the endless assortment businesses, (Zoro in the U.S. and MonotaRO in Japan), and smaller 
high-touch, high-service businesses in Europe, Asia and Mexico.

Business Environment
Given Grainger's large number of customers and the diverse industries it serves, several economic factors and industry 
trends tend to shape Grainger’s business environment and provide general insight into projecting Grainger's growth.  
Grainger’s sales in the U.S. and Canada tend to positively correlate with Business Investment, Business Inventory, 
Exports, Industrial Production and Gross Domestic Product (GDP). Sales in Canada also tend to positively correlate 
with oil prices. The table below provides these estimated indicators for 2018 and 2019:

Source: Global Insight U.S. (January 2019), Global Insight Canada (January 2019)

In the U.S., Business Investment and Exports are two major indicators of MRO spending. Per the Global Insight January 
2019 forecast, Business Inventory and Exports are forecast to improve while Business Investment, Industrial Production 
and  GDP  are  forecast  to  slow,  yet  still  remain  stable  during  2019  despite  slowing  global  growth,  financial  market 
volatility and fading fiscal stimulus.

Per the Global Insight January 2019 forecast, Canada's Business Investment, Exports and Industrial Production are 
expected to slow due to a reduction in spending and oil production quotas and increasing interest rates. 

Outlook

Each business in Grainger’s portfolio has a specific set of strategic imperatives focused on creating unique value for 
customers. 

In the U.S. business, Grainger is focused on growing market share through the three pillars of its strategy: (i) building 
advantaged MRO solutions, which means being able to get customers the exact product they need to solve a problem 
quickly; (ii) offering differentiated sales and services; Grainger has an advantage in serving complex businesses at 
their place of business through its direct customer relationships and onsite services and (iii) enabling flawless order 
to cash; Grainger is committed to providing the absolute best customer experience in the industry through its effort to 
deliver flawlessly on every customer transaction. 

19

The Canada business is focused on stabilizing volume performance in 2019 after completing the majority of its cost 
structure reset.  

In other businesses, the Company is focused on growing the endless assortment businesses profitably, investing in 
product assortment and innovating around customer acquisition by building marketing and analytics capabilities. The 
high-touch,  high-service  international  businesses  are  focused  on  the  same  initiatives  as  the  U.S.  business,  as 
mentioned above. 

Matters Affecting Comparability
There were 255 sales days in the full years 2018 and 2016 versus 254 sales days in the full year 2017. Grainger 
completed one divestiture in 2017, which was immaterial.

2018 Compared to 2017
Grainger's net sales of $11,221 million for 2018 increased $796 million, or 8%, compared to the same period in 2017. 
On a daily basis, net sales increased 7%. The increase in net sales was primarily driven by volume increases in the 
U.S. business due to market share gain and an improved demand environment and continued double digit growth in 
the  endless  assortment  businesses,  offset  by  lower  sales  in  the  Canada  business.  See  Note  17  to  the  Financial 
Statements and refer to the Segment Analysis below for further details.

Gross profit of $4,348 million for 2018 increased $250 million, or 6% compared with the same period in 2017. The 
gross profit margin of 38.7% decreased 0.6 percentage points when compared to the same period in 2017. The lower 
gross  profit  margin  reflects  a  0.5  percentage  point  decline  from  the  implementation  of  the  Financial Accounting 
Standards  Board  (FASB)  new  revenue  recognition  standard  that  primarily  reclassified  certain  costs  related  to 
KeepStock®  services  from  Selling,  general  and  administrative  expenses  (SG&A)  to  Cost  of  goods  sold  (COGS). 
Excluding this impact, gross profit margin would have decreased 0.1 percentage point compared to the prior year.

The tables below reconcile reported SG&A, operating earnings and net earnings attributable to W.W. Grainger, Inc., 
determined in accordance with Generally Accepted Accounting Principles (GAAP) in the United States of America to 
adjusted SG&A, operating earnings and net earnings attributable to W.W. Grainger, Inc., which are all considered non-
GAAP measures. The Company believes that these non-GAAP measures provide meaningful information to assist 
shareholders in understanding financial results and assessing prospects for future performance as they provide a 
better baseline for analyzing the ongoing performance of its businesses by excluding items that may not be indicative 
of  core  operating  results.  Because  non-GAAP  financial  measures  are  not  standardized,  it  may  not  be  possible  to

SG&A of $3,190 million for 2018 increased $127 million, or 4% from $3,063 million compared with the same period in 
2017.  In  the  third  quarter  of  2018  Grainger  recorded  $139  million  of  impairment  charges  related  to  goodwill  and 
tradename intangible asset at the Cromwell business. Excluding restructuring and impairment charges net of branch 
gains and other charges in both periods as noted in the table above, SG&A increased $40 million or 1%, driven primarily 
by higher variable costs in connection with higher sales.

Operating earnings of $1,158 million for 2018 increased $123 million, or 12% from $1,035 million for 2017. Excluding 
restructuring and impairment charges net of branch gains and other charges in both periods as noted in the table 
above,  operating  earnings  increased  $197  million,  or  17%,  driven  primarily  by  higher  sales  and  improved  SG&A  
leverage.

Other expense, net was $77 million in 2018, a decrease of $22 million, or 22% compared to the same period in 2017. 
The  decrease  in  expense  was  primarily  due  to  lower  losses  from  the  conclusion  of  the  Company's  clean  energy 
investments during the second half of 2018.

Income taxes of $258 million in 2018 decreased $55 million, or 18% compared with $313 million for the same period 
in 2017. Grainger's effective tax rates were 23.9% and 33.5% in 2018 and 2017, respectively. The lower effective tax 
rate in 2018 was primarily due to the impact of the Tax Cuts and Jobs Act (the Tax Act) and excess tax benefits from 
stock-based awards, partially offset by the impact of nondeductible goodwill impairment. The 2017 effective tax rate 
was impacted by the wind-down of the Colombia business and the inability to realize the associated tax benefit. In 
addition, Grainger recognized a net tax benefit of $3.2 million for the year ended December 31, 2017, related to the 
impact of the Tax Act. 

Net earnings attributable to W.W. Grainger, Inc. for 2018 increased $196 million, or 33% to $782 million from $586 
million in the same period in 2017. The increase in net earnings primarily resulted from higher operating earnings and 
lower income taxes. Excluding restructuring and impairment charges net of branch gains and other charges and income 
taxes net from both periods as noted in the table above, net earnings increased $282 million, or 42%. 

Diluted earnings per share of $13.73 in 2018 increased 37% compared to $10.02 for the same period in 2017, due to 
higher net earnings and lower average shares outstanding. Excluding restructuring and impairment charges net of 
branch gains and other charges net of income taxes from both periods in the table above, diluted earnings per share 
would have been $16.70 compared to $11.46 in 2017, an increase of 46%.

Grainger's net sales were $10,425 million for 2017, an increase of 3% when compared with net sales of $10,137 million

The increase in net sales was primarily driven by the endless assortment businesses in the U.S. and Japan, as well 
as volume increases in the U.S. business as a result of the pricing actions. The U.S. business pricing actions were 
primarily implemented in the first and third quarters of 2017 and included adjusting list price and introducing new lower 
web prices on the entire business assortment, which drove faster growth in 2017 through share gains with existing 
customers and acquisition of new customers. Refer to the Segment Analysis below for further details

Gross profit of $4,098 million for 2017 decreased by $17 million compared with $4,115 million for 2016. The gross 
profit margin for 2017 was 39.3%, a decrease of 1.3 percentage points compared with 2016, driven primarily by the 
pricing actions in the U.S. business.

SG&A of $3,063 million for 2017 increased 2% from $3,002 million for 2016. Excluding restructuring and impairment 
charges  net  of  branch  gains  and  other  charges  in  both  periods  as  noted  in  the  table  above,  operating  expenses 
increased 3%, driven primarily by higher employee-related costs.

Operating earnings of $1,035 million for 2017 decreased 7% from $1,113 million for 2016. Excluding restructuring and 
impairment charges net of branch gains and other charges in both periods as noted in the table above, operating 
earnings decreased 9% or $113 million, driven primarily by lower gross profit and higher operating expenses.

24

Other expense, net was $99 million in 2017 compared to $94 million of expense in 2016. The increase in expense 
was primarily due to incremental interest expense on $400 million in long-term debt issued in May 2016 and $400 
million in long-term debt issued in May 2017, as well as higher operating losses from the Company's clean energy 
investments partially offset by higher benefits related to the Company's postretirement plan. See Note 10 to the Financial 
Statements for additional information. 

Income taxes of $313 million in 2017 decreased 19% compared with $386 million in 2016. Grainger's effective tax 
rates were 33.5% and 37.9% in 2017 and 2016, respectively. The lower rate versus the prior year is primarily due to 
discrete tax items and U.S. tax legislation. 

On December 22, 2017, the Tax Act was signed into law, which significantly revised the U.S. corporate income tax 
system by lowering corporate income tax rates from 35% to 21% effective January 1, 2018, allowing accelerated 
expensing of qualified capital investments for a specific period, limiting net interest expense deductions and transitioning 
U.S. international taxation from a worldwide to a territorial tax system, among other changes. Grainger recognized a 
net provisional tax benefit of $3.2 million for the year ended December 31, 2017, related to the estimated impact of 
the Tax Act. See Note 15 to the Financial Statements for additional information.

Net earnings attributable to W.W. Grainger, Inc. for 2017 decreased by 3% to $586 million from $606 million in 2016. 
The decrease in net earnings primarily resulted from lower operating earnings, partially offset by lower income taxes. 
Excluding restructuring and impairment charges net of branch gains and other charges net of income tax and discrete 
tax items from both years mentioned in the table above, net earnings decreased 6%.  

Diluted  earnings  per  share  of  $10.02  in  2017  were  2%  higher  than  $9.87  for  2016,  due  to  lower  average  shares 
outstanding partially offset by lower earnings. Excluding restructuring and impairment charges net of branch gains and 
other charges net of income taxes in the table above, diluted earnings per share would have been $11.46 compared 
to $11.58 in 2016, a decrease of 1%.

Segment Analysis - 2018 Compared to 2017

The following comments at the reportable segment and other business unit level include external and intersegment 
net sales and operating earnings. See Note 17 to the Financial Statements.

United States
Net sales were $8,588 million for 2018, an increase of $628 million, or 8% when compared with net sales of $7,960 
million for 2017. On a daily basis, the 7% increase consisted of the following:

Sales to customers in the government end market increased in the low teens and natural resources increased in the 
high single digits. Retail/wholesale, commercial and heavy manufacturing end markets increased in the mid-single 
digits. Contractors increased in the low single digits while the light manufacturing end segment was flat year over year. 
Overall, revenue increases were primarily driven by market share gains and improved demand in all industries, partially 
offset by the Company's pricing actions and the July 2017 divestiture of a specialty business. See Note 2 to the Financial 
Statements.

Gross profit margin decreased 0.7 percentage point compared to the same period in  2017. The decline was primarily 
driven by 0.5 percentage point due to the implementation of the FASB's new revenue recognition standard. Excluding 
the  impact  of  the  implementation  of  the  new  revenue  recognition  standard,  gross  profit  margin  would  have  been 
unfavorable by 0.2 percentage points.

SG&A for 2018 increased 3% compared to the same period in 2017. This increase was primarily driven by variable 
compensation  to  reflect  stronger  performance,  partially  offset  by  the  implementation  of  the  FASB's  new  revenue 
recognition standard.

25

Operating earnings of $1,338 million increased $138 million, or 12% from $1,200 million in the same period of 2017. 
This increase was driven primarily by higher sales, higher gross profit dollars and improved SG&A leverage. 

Canada
Net sales were $653 million for 2018, a decrease of $100 million, or 13% when compared with $753 million for 2017.  
On a daily basis, the 14% decrease consisted of the following:

Volume

(14)%

During 2018, volume decreased by 23 percentage points compared to the same period in 2017 due to branch closures 
and sales coverage optimization activities, partially offset by price increases and continued contract negotiations of 9 
percentage points for 2018.

Gross profit margin increased 2.9 percentage points in 2018 compared to the same period in 2017, primarily due to 
3.9 percentage points from price increases that began in late 2017 and improved customer mix, net of 1.0 percentage 
point from the implementation of the new revenue recognition standard.

SG&A decreased $40 million, or 13% in 2018 compared to the same period in 2017. The decrease was primarily due 
to cost reduction actions and lower variable expense on lower sales volume.

Operating losses were $49 million for 2018 compared to losses of $77 million in the same period in 2017. Excluding 
restructuring and impairment charges net of branch gains and other charges in both periods (as noted in the table 
above and Note 7 to the Financial Statements), operating losses would have been $14 million compared to $37 million 
in the prior period primarily due to lower SG&A and lower sales volume.

Other businesses
Net sales for other businesses were $2,441 million for 2018, an increase of $321 million, or 15%, when compared to  
the same period in 2017. The net sales increase was primarily due to incremental sales at Zoro and MonotaRO. On 
a daily basis, the 15% increase consisted of the following:

The net sales increase was primarily due to growth in the endless assortment businesses as a result of increased 
customer acquisition and incremental sales in other international businesses. Foreign currencies strengthened in the 
countries where the Company operates. These currencies primarily include the euro, pound sterling and yen.

Operating earnings for other businesses were $8 million for 2018, a decrease of $48 million, or 86% compared to $56 
million for 2017. Other businesses included impairment charges in 2018 relating to the Cromwell business in the U.K. 
See Note 4 and Note 7 to the Financial Statements. Excluding restructuring and impairment charges net of branch 
gains and other charges in both periods, operating earnings increased $42 million or 38%, primarily due to strong 
performance from the endless assortment businesses.

Sales to customers in natural resources, resellers and retail end markets increased mid-single digits, while heavy 
manufacturing  and  government  increased  low  single  digits.  The  sales  growth  was  partially  offset  by  declines  in 
contractors and commercial services. Volume increased year over year, primarily driven by the pricing actions.

Gross profit margin decreased 1.7 percentage points in 2017 compared to 2016, driven by price deflation exceeding 
higher volume in response to pricing actions.

SG&A of $2,007 decreased by 1% for 2017 compared to 2016. Excluding restructuring and impairment charges net 
of branch gains and other charges in both periods, operating expenses increased 1% or $26 million, driven by higher 
employee related costs. See Note 7 to the Financial Statements. 

Operating earnings of $1,200 million for 2017 decreased 5% compared to $1,269 million in 2016. Excluding restructuring 
and impairment charges net of branch gains and other charges in both periods, operating earnings decreased 9% or 
$123 million, driven primarily by price deflation. See Note 7 to the Financial Statements. 

Canada
Net sales were $753 million for 2017, an increase of $19 million, or 3%, when compared with $734 million for 2016.  
On a daily basis, the 3% increase consisted of volume across all end segments. 

Gross profit margin increased 1.0 percentage point in 2017 versus 2016, primarily due to a favorable comparison to 
an inventory adjustment in the second quarter of 2016 that did not repeat in 2017, partially offset by price deflation, 
cost inflation and higher freight costs from an increase in shipping directly to customers in 2017. 

SG&A decreased 9% in 2017 versus 2016. Excluding restructuring and impairment charges net of branch gains and 
other charges in both periods as noted in the table above, operating expenses would have increased 3%, primarily 
related to higher professional service fees related to the business transformation. 

Operating  losses  of  $77  million  for  2017  increased  versus  operating  losses  of  $65  million  in  2016.  Excluding  the 
restructuring and impairment charges net of branch gains and other charges and the inventory adjustment mentioned 
in the table above, operating losses would have been $37 million compared to $41 million in the prior year. 

Other businesses
Net sales for other businesses were $2,120 million for 2017, an increase of $235 million, or 12%, when compared to 
$1,885 million for 2016. The net sales increase was primarily due to incremental sales at Zoro and MonotaRO. On a

Operating  earnings  for  other  businesses  were  $56  million  for  2017  compared  to  $40  million  for  2016.  Excluding 
restructuring charges in 2017 and the goodwill and intangible impairment charges of $52 million in the Fabory and 
Colombia businesses in the prior year, operating earnings increased $18 million or 19%, due to strong performance 
from the endless assortment businesses. 

Financial Condition
Grainger expects its strong working capital position, cash flows from operations and borrowing capacity to continue, 
allowing it to fund its operations, growth initiatives and capital expenditures as well as pay cash dividends, repurchase 
shares and repay its long-term debt obligations while maintaining an adequate credit rating. 

Cash and Cash Equivalents
At December 31, 2018, 2017 and 2016, Grainger had cash and cash equivalents of $538 million, $327 million and 
$274 million, respectively. Approximately 49%, 66% and 71% were outside the U.S. business as of December 31, 
2018, 2017 and 2016, respectively.  Grainger has no material limits or restrictions on its ability to use these foreign 
liquid assets. 

Cash Flow

2018 Compared to 2017
Net cash provided by operating activities was $1,057 million for the twelve months ended December 31, 2018 and 
2017, as increased net earnings were offset by investment in inventory and timing of payables. 

Net cash used in investing activities was $166 million and $146 million for the twelve months ended December 31, 
2018 and 2017, respectively. The increase in net cash used in investing activities was driven by lower proceeds primarily 
from the sales of branch real estate assets in the U.S. and a U.S. business divestiture when compared to the prior 
year. 

Net cash used in financing activities was $670 million and $867 million in the twelve months ended December 31, 
2018 and 2017, respectively. The decrease in net cash used in financing activities was primarily driven by lower stock 
repurchases in 2018 compared to 2017 and higher proceeds from the exercise of stock options. 

2017 Compared to 2016
Net cash provided by operating activities was $1,057 million and $1,024 million for the twelve months ended December 
31, 2017 and 2016, respectively. The increase in cash provided by operating activities is primarily the result of higher 
accruals related to employee benefits, partially offset by lower earnings and higher working capital.

Net cash used in investing activities was $146 million and $262 million for the twelve months ended December 31, 
2017 and 2016, respectively.  The decrease in net cash used in investing activities was driven by lower additions to 
property, buildings and equipment compared to the prior year and higher proceeds primarily from the sales of branch 
real estate assets in the U.S. and a U.S. business divestiture when compared to the prior year. 

Net cash used in financing activities was $867 million and $776 million in the twelve months ended December 31, 
2017 and 2016, respectively. The increase in net cash used in financing activities was primarily driven by higher net 
payments of commercial paper, offset by lower stock repurchases in 2017 compared to 2016 and lower payments of 
long-term debt. 

Working Capital
Internally generated funds are the primary source of working capital and funds used for growth initiatives and capital 
expenditures. Grainger's working capital is not impacted by significant seasonality trends throughout the year.

Working capital consists of current assets (less non-operating cash) and current liabilities (less short-term debt and 
current maturities of long-term debt).  Working capital was $1,898 million at December 31, 2018, compared with $1,669 
million at December 31, 2017, primarily due to an increase in accounts receivable and inventory and decreases in 
accounts payable. At these dates, the ratio of current assets to current liabilities was 2.4 and 2.2, respectively.

In 2018, the Company continued to invest in its North American distribution network (e.g. new or expanding existing 
facilities and technology). Other investments include the consolidation of facility and office locations and development 
of software solutions.

In 2017, the Company continued to invest in its worldwide distribution network (e.g. new or expanding existing facilities 
and  technology),  digital  platforms  (e.g.  eCommerce  websites  and  inventory  management  solutions),  capital 
maintenance of its existing branch networks across the enterprise and other supporting information technology assets.

In 2016, the Company continued to invest in the North America distribution network, as well as the distribution network 
in other businesses and sales productivity initiatives. Other significant investments in 2016 included the eCommerce 
platform, sustaining capital investments in branches and distribution centers and other technology infrastructure. 

In 2019, capital expenditures are expected to range from $300 million to $350 million. Projected spending includes 
continued  investments  in  the  supply  chain,  investment  in  a  DC  in  Japan,  software  development  and  inventory 
management solutions. Grainger expects to fund 2019 capital spending primarily from operating cash flows.

Debt
Grainger maintains a debt ratio and liquidity position that provides flexibility in funding working capital needs and long-
term cash requirements. In addition to internally generated funds, Grainger has various sources of financing available, 
including bank borrowings under lines of credit. Total debt, which is defined as total interest-bearing debt (short-term 
current and long-term) as a percent of total capitalization was 51.5% and 56.2%, as of December 31, 2018 and 2017, 
respectively.

In the years 2015-2017, Grainger issued $1.8 billion in long-term debt to partially fund the repurchase of $2.8 billion 
in shares of the total $3 billion previously announced. The remaining share repurchases were funded from internally 
generated cash. Debt was issued as follows:

• 
• 
• 

In June 2015, $1.0 billion payable in 30 years and carries a 4.60% interest rate, payable semiannually.
In May 2016, $400 million payable in 30 years and carries a 3.75% interest rate, payable semiannually.
In May 2017, $400 million payable in 30 years and carries a 4.20% interest rate, payable semiannually.

See Notes 8, 9 and 11 to the Financial Statements for further detail related to debt, interest on debt and operating 
lease obligations.

Purchase obligations are made in the normal course of business to meet operating needs. While purchase orders for 
both  inventory  purchases  and  non-inventory  purchases  are  generally  cancelable  without  penalty,  certain  vendor 
agreements provide for cancellation fees or penalties depending on the terms of the contract. 

Other liabilities represent future payments for profit sharing and other employee benefit plans. 

The Company’s obligation for the postretirement healthcare benefits plan, as determined by actuarial projections, is 
$190 million at December 31, 2018. The Company has established a Group Benefit Trust (Trust) to fund the plan 
obligations. The Trust assets available for benefits payments are $176 million at December 31, 2018. The Company 
has no minimum funding requirements and  the timing and amounts of the Company’s additional contributions into the 
Trust have not been determined. Other employment-related benefits obligations of $53 million have also not been 
included in this table as the timing of benefit payments is not predictable. See Note 10 to the Financial Statements for 
further detail.

Grainger  has  recorded  a  noncurrent  liability  of  approximately  $41  million  for  tax  uncertainties  and  interest  at 
December 31, 2018. This amount is excluded from the table above, as Grainger cannot predict the timing of these 
cash payments by period. See Note 15 to the Financial Statements.

Off-Balance Sheet Arrangements
Grainger  does  not  have  any  material  exposures  to  off-balance  sheet  arrangements.  All  significant  contractual 
obligations  are  recorded  on  the  Company's  Consolidated  Balance  Sheet  or  disclosed  in  the  notes  to  Grainger's 
Consolidated Financial Statements. 

Critical Accounting Estimates
Note  1  to  the  Financial  Statements  describes  the  significant  accounting  policies  used  in  the  preparation  of  the 
Consolidated Financial Statements. As discussed in Note 1, the preparation of financial statements, in conformity with 
U.S. GAAP, requires management to make judgments, estimates and assumptions about future events that affect the 
amounts reported in the financial statements and accompanying notes.

Accounting policies and estimates are considered critical when they require management to make subjective and 
complex judgments, estimates and assumptions about matters that have a material impact on Grainger's financial 
statements and accompanying notes. 

30

The  Company  believes  that  the  following  discussion  addresses  Grainger’s  most  critical  accounting  policies  and 
estimates.

Inventory Reserves 
Grainger establishes inventory reserves for excess and obsolete inventory. Grainger regularly reviews inventory to 
evaluate  continued  demand  and  identify  any  obsolete  or  excess  quantities. Grainger  records  provisions  for  the 
difference between excess and obsolete inventory cost and its estimated realizable value. Estimated realizable value 
is  based  on  anticipated  future  product  demand,  market  conditions  and  liquidation  values. As  Grainger's  inventory 
consists of approximately 1.7 million stocked products, it is not practical to quantify the actual disposition of excess 
and  obsolete  inventory  against  estimated  amounts  at  a  stock  keeping  unit  (SKU)  level  and  no  individual  SKU  is 
material. There were no material differences noted between reserve levels compared to the level of write-offs historically. 

Grainger's methodology for estimating reserves is continually evaluated based on current experience and provides 
for a materially accurate level of reserves at any reporting date. Actual results could differ materially from projections 
and  require  changes  to  reserves  that  could  have  a  material  effect  on  Grainger's  results  of  operations,  based  on 
significant changes in product demand, market conditions or liquidation value. If business or economic conditions 
change, Grainger's estimates and assumptions may be revised as appropriate. For fiscal years 2018, 2017 and 2016, 
actual results did not vary materially from estimated amounts.

Goodwill and Indefinite-Lived Intangible Assets 
Grainger’s  goodwill  and  indefinite-lived  intangible  assets  are  evaluated  for  impairment  annually  during  the  fourth 
quarter, or more frequently if an event occurs or circumstances change. The Company tests for impairment by first 
assessing qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit or 
indefinite-lived intangible asset is less than its carrying value. Some of the factors considered in the assessment include 
general macroeconomic, industry and market trends and significant events impacting reporting units’ current and future 
performance. If the Company concludes that it is more likely than not that goodwill and intangible assets may be 
impaired, a quantitative impairment test is performed. 

In the quantitative impairment tests, the Company uses the discounted cash flow, market approach and royalty relief 
methods, which require significant assumptions and judgments with respect to future volume, revenue and expense 
growth rates, capital investments, changes in working capital use, the selection of an appropriate discount rate and 
terminal growth rate, among other assumptions and estimates. The use of alternative estimates and assumptions 
could impact the Company’s estimated fair values of reporting units and indefinite-lived intangible assets and potentially 
result  in  different  impacts  on  the  Company’s  results  of  operations. Actual  results  could  differ  from  the  Company’s 
assumptions and estimates. See Note 4 to the Financial Statements for further information. 

Income Taxes 
The tax balances and income tax expense recognized by Grainger are based on management's interpretations of the 
tax laws of multiple jurisdictions. Income tax expense reflects Grainger's best estimates and assumptions regarding, 
among other items, the level of future taxable income, interpretation of tax laws and tax planning opportunities, plans 
for reinvestment of cash overseas and uncertain tax positions. On December 22, 2017, the Tax Cuts and Jobs Act 
was signed into law, which significantly revised the U.S. corporate income tax system including lowering the corporate 
income tax rates from 35% to 21% effective January 1, 2018. See Note 15 to the Financial Statements for additional 
information. 

Future rulings by tax authorities and future changes in tax laws and their interpretation, changes in projected levels of 
taxable income, changes in planned need for cash overseas and future tax planning strategies could impact the actual 
effective tax rate and tax balances recorded by Grainger. 

Contingent Liabilities 
At any time, Grainger may be subject to investigations, legal proceedings or claims related to the ongoing operation 
of its business, including claims both by and against Grainger. Such proceedings typically involve claims related to 
product liability, general negligence, contract disputes, environmental issues, unclaimed property, wage and hour laws, 
intellectual property, employment practices, regulatory compliance or other matters and actions brought by employees, 
customers, competitors, suppliers or governmental entities. As a government contractor selling to federal, state and 
local governmental entities, the Company is also subject to governmental or regulatory inquiries or audits or other 
proceedings, including those related to contract administration or to pricing compliance. Grainger retains a significant 
portion of the risk of certain losses related to workers' compensation, auto liability, general liability and property losses 

31

through the utilization of high deductibles and self-insured retentions. Grainger routinely assesses the likelihood of 
any adverse outcomes related to these matters on a case by case basis, as well as the potential ranges of losses and 
fees. Grainger establishes accruals for its potential exposures, as appropriate, for claims against Grainger when losses 
become probable and the financial impact of an adverse outcome is reasonably estimable. Legal fees are recognized 
as incurred and are not included in accruals for contingencies. Where Grainger is able to reasonably estimate a range 
of potential losses, Grainger records the amount within that range that constitutes Grainger's best estimate. Grainger 
also discloses the nature of and range of loss for claims against Grainger when losses are reasonably possible and 
the exposure is considered material to Grainger's Consolidated Financial Statements. These accruals and disclosures 
are  determined  based  on  the  facts  and  circumstances  related  to  the  individual  cases  and  require  estimates  and 
judgments regarding the interpretation of facts and laws, as well as the effectiveness of strategies or other factors 
beyond Grainger's control. If the assessment of any of these factors changes, the estimates may change. Predicting 
the outcome of claims and litigation and estimating related costs and exposure involves substantial uncertainties that 
could cause actual costs to vary materially from estimates and accruals.

Other 
Other significant accounting policies, not involving the same level of measurement uncertainties as those discussed 
above, are nevertheless important to an understanding of the financial statements. Policies such as revenue recognition, 
depreciation, intangibles, long-lived assets, fair value measurements and valuations and warranties require judgments 
on complex matters that are often subject to multiple external sources of authoritative guidance such as the Financial 
Accounting  Standards  Board  and  the  Securities  and  Exchange  Commission.  Possible  changes  in  estimates  or 
assumptions associated with these policies are not expected to have a material effect on the financial condition or 
results of operations of Grainger. More information on these additional accounting policies can be found in Note 1 to 
the Financial Statements.

Effects of Inflation and Changing Prices
Grainger is affected by inflation through increased product and operating costs, and the ability to pass on cost increases 
to customers over time is dependent upon market conditions. The ability to achieve sales growth through increased 
prices is also subject to inflation and normal competitive conditions. The predominant use of the last-in, first-out (LIFO) 
method of accounting for inventories and accelerated depreciation methods for financial reporting and income tax 
purposes result in a substantial recognition of the effects of inflation in the financial statements.

Some  of  Grainger's  products  contain  significant  amounts  of  commodity-priced  materials,  such  as  steel,  copper, 
petroleum  derivatives  or  rare  earth  minerals,  and  are  subject  to  price  changes  based  upon  fluctuations  in  the 
commodities market. 

Grainger believes the most positive means to combat inflation and advance the interests of investors lie in the continued 
application of basic business principles, which include improving productivity, maintaining working capital turnover and 
offering products and services that can command appropriate prices in the marketplace.

Forward-Looking Statements

From time to time, in this Annual Report on Form 10-K, as well as in other written reports, communications and verbal 
statements, Grainger makes forward-looking statements that are not historical in nature but concern forecasts of future 
results,  business  plans,  analyses,  prospects,  strategies,  objectives  and  other  matters  that  may  be  deemed  to  be 
“forward-looking statements” under the federal securities laws. Forward-looking statements can generally be identified 
by their use of terms such as “anticipate,” “estimate,” “believe,” “expect,” “could,” “forecast,” “may,” “intend,” “plan,” 
“predict,” “project” “will” or “would” and similar terms and phrases, including references to assumptions.

Grainger cannot guarantee that any forward-looking statement will be realized and achievement of future results is 
subject to risks and uncertainties, many of which are beyond the Company's control, which could cause Grainger's 
results to differ materially from those that are presented.

Important factors that could cause actual results to differ materially from those presented or implied in the forward-
looking statements include, without limitation: higher product costs or other expenses; a major loss of customers; loss 
or  disruption  of  sources  of  supply;  increased  competitive  pricing  pressures;  failure  to  develop  or  implement  new 
technology initiatives or business strategies; failure to adequately protect intellectual property or successfully defend 
against infringement claims; the implementation, timing and results of the Company's strategic pricing initiatives and 
other  responses  to  market  pressures;  the  outcome  of  pending  and  future  litigation  or  governmental  or  regulatory 

32

proceedings, including with respect to wage and hour, anti-bribery and corruption, environmental, advertising, privacy 
and  cybersecurity  matters;  investigations,  inquiries,  audits  and  changes  in  laws  and  regulations;  disruption  of 
information technology or data security systems; general industry, economic, market or political conditions; general 
global economic conditions; currency exchange rate fluctuations; market volatility, including volatility or price declines 
of the Company's common stock; commodity price volatility; labor shortages; facilities disruptions or shutdowns; higher 
fuel  costs  or  disruptions  in  transportation  services;  natural  and  other  catastrophes;  unanticipated  and/or  extreme 
weather conditions; loss of key members of management; the Company's ability to operate, integrate and leverage 
acquired  businesses;  changes  in  effective  tax  rates  and  other  factors  identified  under  Item  1A:  Risk  Factors  and 
elsewhere in this Form 10-K.

Caution should be taken not to place undue reliance on Grainger's forward-looking statements and Grainger undertakes 
no obligation to update or revise any of its forward-looking statements, whether as a result of new information, future 
events or otherwise, except as required by law.

Item 7A: Quantitative and Qualitative Disclosures About Market Risk

Grainger may use financial instruments to reduce its exposure to adverse fluctuations in foreign currency exchange 
rates and interest rates as part of its overall risk management strategy. The derivative positions reduce risk by hedging 
certain underlying economic exposures. Because  of the high correlation between the hedging instrument and the 
underlying exposure, fluctuations in the value of the instruments are generally offset by reciprocal changes in the value 
of the underlying exposure. Grainger does not enter into derivative financial instruments for trading or speculative 
purposes. 

Foreign Currency Exchange Rates
Grainger’s financial results, including the value of assets and liabilities, are exposed to foreign currency exchange rate 
risk when the financial statements of the business units, as stated in their local currencies, are translated into U.S. 
dollars. While it is difficult to quantify any particular impact of changes in exchange rates, a uniform 10% strengthening 
in the U.S. dollar (whereby all other variables are held constant and unusual expense items described in "Item 7: 
Management's Discussion and Analysis of Financial Condition and Results of Operations" are excluded) would have 
resulted in a decrease in net earnings of $3 million for the year ended December 31, 2018, and an increase in net 
earnings of $1 million for the year ended December 31, 2017. Comparatively, a 10% weakening of the U.S. dollar 
would have resulted in an increase in net earnings of $3 million for the year ended December 31, 2018, and a decrease 
in net earnings of $2 million for the year ended December 31, 2017. This sensitivity analysis of the effects of changes 
in foreign currency exchange rates does not factor in future potential changes in sales levels or local currency prices 
or costs.

Commodity Price Risk
Grainger has limited primary exposure to commodity price risk on certain products for resale, but does not purchase 
commodities directly.

MANAGEMENT'S ANNUAL REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of W.W. Grainger, Inc. (Grainger) is responsible for establishing and maintaining adequate internal 
control over financial reporting. Grainger's internal control system was designed to provide reasonable assurance to 
Grainger's management and Board of Directors regarding the reliability of financial reporting and the preparation of 
financial statements for external purposes in accordance with accounting principles generally accepted in the United 
States of America.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements 
under all potential conditions. Therefore, effective internal control over financial reporting provides only reasonable, 
and not absolute, assurance with respect to the preparation and presentation of financial statements.

Grainger's  management  assessed  the  effectiveness  of  Grainger's  internal  control  over  financial  reporting  as  of 
December 31, 2018, based on criteria established in Internal Control - Integrated Framework issued by the Committee 
of  Sponsoring  Organizations  of  the  Treadway  Commission  (2013  framework)  (the  COSO  criteria).  Based  on  its 
assessment  under  that  framework  and  the  criteria  established  therein,  Grainger's  management  concluded  that 
Grainger's internal control over financial reporting was effective as of December 31, 2018. 

Ernst & Young LLP, an independent registered public accounting firm, has audited Grainger's internal control over 
financial reporting as of December 31, 2018, as stated in their report, which is included herein.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of 
W.W. Grainger, Inc. and Subsidiaries

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of W.W. Grainger, Inc. and subsidiaries (the Company) 
as  of  December  31,  2018  and  2017,  the  related  consolidated  statements  of  earnings,  comprehensive  earnings, 
shareholders’ equity and cash flows for each of the three years in the period ended December 31, 2018, and the related 
notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial 
statements present fairly, in all material respects, the financial position of the Company at December 31, 2018 and 
2017, and the consolidated results of its operations and its cash flows for each of the three years in the period ended 
December 31, 2018, in conformity with U.S. generally accepted accounting principles. 

We also have 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, 2018, based on criteria 
established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the 
Treadway Commission (2013 framework) and our report dated February 28, 2019 expressed an unqualified opinion 
thereon. 

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.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of 
W.W. Grainger, Inc. and Subsidiaries

Opinion on Internal Control over Financial Reporting

We have audited W.W. Grainger, Inc. and subsidiaries’ internal control over financial reporting as of December 31, 
2018, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring 
Organizations of the Treadway Commission (2013 Framework) (the COSO Criteria). In our opinion, W.W. Grainger, 
Inc. and subsidiaries (the Company) maintained, in all material respects, effective internal control over financial reporting 
as of December 31, 2018, based on the COSO criteria. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2018 and 2017, and the 
related consolidated statements of earnings, comprehensive earnings, shareholders’ equity and cash flows for each 
of the three years in the period ended December 31, 2018 and the related notes and our report dated February 28, 
2019 expressed an unqualified opinion thereon. 

Basis for Opinion 

The Company’s management is responsible for maintaining effective internal control over financial reporting and for 
its  assessment  of  effectiveness  of  the  internal  control  over  financial  reporting  included  in  the  accompanying 
Management’s Annual Report on Internal Controls 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.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

COMPANY BACKGROUND
W.W.  Grainger,  Inc.  is  a  broad  line,  business-to-business  distributor  of  maintenance,  repair  and  operating  (MRO) 
products and services. W.W. Grainger, Inc.'s operations are primarily in the United States (U.S.), Canada, Europe, 
Japan and Mexico. In this report, the words “Company” or “Grainger” mean W.W. Grainger, Inc. and its subsidiaries. 

PRINCIPLES OF CONSOLIDATION
The Consolidated  Financial  Statements include  the  accounts  of the Company  and  its subsidiaries  over which  the 
Company exercises control. All significant intercompany transactions are eliminated from the consolidated financial 
statements.  The  Company  has  a  controlling  ownership  interest  in  MonotaRO  Co.,  Ltd.  (MonotaRO),  the  endless 
assortment (single channel) business in Japan, with the residual representing the noncontrolling interest. 

USE OF ESTIMATES
The preparation of financial statements in conformity with accounting principles generally accepted in the United States 
of America requires management to make estimates and assumptions that affect the reported amounts of assets and 
liabilities, revenues and expenses and the disclosure of contingent liabilities. Actual results could differ from those 
estimates.

FOREIGN CURRENCY TRANSLATION
The U.S. dollar is the reporting currency for all periods presented. The financial statements of the Company’s foreign 
operating subsidiaries are measured using the local currency as the functional currency. Assets and liabilities of the 
Company’s foreign operating subsidiaries are translated into U.S. dollars at the exchange rate in effect at the balance 
sheet date.  Revenues and expenses are translated at average rates in effect during the period.  Net exchange gains 
or  losses  resulting  from  the  translation  of  financial  statements  of  foreign  operations  are  recorded  as  a  separate 
component  of  other  comprehensive  earnings.  See  Note  14  to  the  Consolidated  Financial  Statements  (Financial 
Statements). Foreign currency transaction gains and losses are included in the Consolidated Statement of Earnings.

RECLASSIFICATIONS
Certain amounts in the 2017 and 2016 financial statements, as previously reported, have been reclassified to conform 
to the 2018 presentation. In March 2017, the Financial Accounting Standards Board (FASB) issued Accounting Standard 
Update (ASU) 2017-07, Compensation Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic 
Pension Cost and Net Periodic Postretirement Benefit Cost  (ASU 2017-07), which became effective January 1, 2018.
See Note 10 to the Financial Statements.

REVENUE RECOGNITION
The Company recognizes revenue when a sales arrangement with a customer exists (e.g., contract, purchase orders, 
others), transaction price is fixed or determinable and the Company has satisfied its performance obligation per the 
sales arrangement. The Company's sales arrangements generally have standard payment terms that do not exceed 
a year.

The majority of Company revenue originates from contracts with a single performance obligation to deliver products, 
whereby the Company’s performance obligations are satisfied when control of the product is transferred to the customer 
per the arranged shipping terms. Some Company contracts contain a combination of product sales and services, which 
are  distinct  and  accounted  for  as  separate  performance  obligations.  The  Company’s  performance  obligations  for 
services are satisfied when the services are rendered within the arranged service period. Total service revenue is not 
material and accounted for approximately 1% of total Company revenue for the twelve months ended December 31, 
2018.

The Company records a contract asset when it has a right to payment from a customer that is conditioned on events 
other than the passage of time. The Company also records a contract liability when customers prepay but the Company 
has not yet satisfied its performance obligation. The Company did not have any material unsatisfied performance 
obligations, contract assets or liabilities as of December 31, 2018 and 2017.

The Company’s revenue is reported as Net sales and is measured at the determinable transaction price, net of any 
variable considerations (e.g., rights to return product, sales incentives, others) and any taxes collected from customers 
and subsequently remitted to governmental authorities. The Company considers shipping and handling as activities 
to fulfill its performance obligation. Billings for freight are accounted for as Net sales and shipping and handling costs 
are accounted for in Cost of goods sold.

46

The Company offers customers rights to return product and sales incentives, which primarily consist of volume rebates. 
The Company’s terms for product returns and sales incentives generally do not exceed a year. The Company estimates 
sales returns and volume rebate accruals throughout the year based on various factors, including contract terms, 
historical experience and performance levels. Total accrued sales returns were approximately $29 million and $28 
million as of  December 31, 2018 and 2017, respectively, and are reported as a reduction of Accounts receivable, net. 
Total accrued sales incentives were approximately $62 million and $55 million as of December 31, 2018 and 2017, 
respectively, and are reported as part of Accrued expenses.

COST OF GOODS SOLD (COGS)
COGS includes products and product-related costs, vendor consideration, shipping and handling costs and service 
costs.

The Company receives rebates and allowances from its vendors to promote their products, which are recorded as a 
reduction to COGS unless the considerations are directly identifiable to specific costs incurred to promote vendor 
products. 

Rebates earned from vendors that are based on product purchases are capitalized into inventory as part of product 
purchase price. These rebates are credited to COGS based on sales. Vendor rebates that are earned based on products 
sold are credited directly to COGS.

ADVERTISING
Advertising costs are generally expensed in the year the related advertisement is first presented. Catalog expense is 
amortized equally to expense over the life of the catalog, generally one year, beginning in the month of its distribution. 
Advertising expense, which includes digital marketing costs and catalog amortization, was $241 million, $187 million
and $180 million for 2018, 2017 and 2016, respectively. 

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES (SG&A)
Included in this category are purchasing, supply chain and branch operations, information services and marketing and 
selling expenses, as well as other types of general and administrative costs.

STOCK INCENTIVE PLANS
The  Company  measures  all  share-based  payments  using  fair-value-based  methods  and  records  compensation 
expense related to these payments over the vesting period net of estimated forfeitures. See Note 12 to the Financial 
Statements. 

INCOME TAXES
Income taxes are recognized during the year in which transactions enter into the determination of financial statement 
income, with deferred taxes being provided for temporary differences between financial and tax reporting.  The Company 
recognizes  in  the  financial  statements  a  provision  for  tax  uncertainties,  resulting  from  application  of  complex  tax 
regulations  in  multiple  tax  jurisdictions.  The  Company  evaluates  deferred  income  taxes  to  determine  if  valuation 
allowances are required using a “more likely than not” standard. This assessment considers the nature, frequency and 
amount of book and taxable income and losses, the duration of statutory carryback and forward periods, future reversals 
of existing taxable temporary differences and tax planning strategies, among other matters. See Note 15 to the Financial 
Statements. 

OTHER COMPREHENSIVE EARNINGS (LOSSES)
The  Company's  Other  comprehensive  earnings  (losses)  include  foreign  currency  translation  adjustments  and 
unrecognized  gains  (losses)  on  postretirement  and  other  employment-related  benefit  plans.  Accumulated  other 
comprehensive earnings (losses) (AOCE) are presented separately as part of shareholders' equity. See Note 14 to 
the Financial Statements.

CASH AND CASH EQUIVALENTS
The Company considers investments in highly liquid debt instruments, purchased with an original maturity of 90 days 
or less, to be cash equivalents.

47

CONCENTRATION OF CREDIT RISK
The Company places temporary cash investments with institutions of high credit quality and, by policy, limits the amount 
of credit exposure to any one institution.

The Company has a broad customer base representing many diverse industries doing business in North America, 
Europe and Asia. Consequently, no significant concentration of credit risk is considered to exist.

ACCOUNTS RECEIVABLE AND ALLOWANCE FOR DOUBTFUL ACCOUNTS
Accounts receivable are stated at their estimated net realizable value. The Company establishes reserves for customer 
accounts that are potentially uncollectible. The method used to estimate the allowances is based on several factors, 
including the age of the receivables and the historical ratio of actual write-offs to the age of the receivables. These 
analyses also take into consideration economic conditions that may have an impact on a specific industry, group of 
customers or a specific customer. When it is determined that customer accounts cannot be collected, the receivable 
balances are charged to the allowance for doubtful accounts. See Note 5 to the Financial Statements.

INVENTORIES
Inventories are valued at the lower of cost or net realizable value. Cost is determined primarily by the last-in, first-out 
(LIFO) method, which accounts for approximately 66% of total inventory. Grainger uses LIFO method to better match 
inventory cost and revenue. For the remaining inventory, cost is determined by the first-in, first-out (FIFO) method.

Grainger  regularly  reviews  inventory  to  evaluate  continued  demand  and  identify  any  obsolete  or  excess 
quantities. Grainger records provisions for the difference between excess and obsolete inventory cost and its estimated 
realizable value. See Note 6 of the Financial Statements.

PROPERTY, BUILDINGS AND EQUIPMENT
Property, buildings and equipment are valued at cost. For financial statement purposes, depreciation and amortization 
are recorded in amounts sufficient to relate the cost of depreciable assets to operations over their estimated service 
lives,  principally  on  the  declining-balance  and  sum-of-the-years-digits  depreciation  methods.  The  Company's 
international businesses record depreciation expense primarily on a straight-line basis. The principal estimated useful 
lives for determining depreciation are as follows:

Buildings, structures and improvements
Furniture, fixtures, machinery and equipment

10 to 30 years
3 to 10 years

Depreciation expense was $162 million, $170 million and $166 million for the years ended December 31, 2018, 2017 
and 2016, respectively.

Improvements to leased property are amortized over the initial terms of the respective leases or the estimated service 
lives of the improvements, whichever is shorter. 

The Company capitalized interest costs of $10 million, $2 million and $2 million for the years ended December 31, 
2018, 2017 and 2016, respectively.

LONG-LIVED ASSETS
The carrying value of long-lived assets, primarily property, buildings and equipment and amortizable intangibles, is 
evaluated whenever events or changes in circumstances indicate that the carrying value of the asset may be impaired. 
An impairment loss is recognized when estimated undiscounted future cash flows resulting from use of the asset, 
including disposition, are less than the carrying value of the asset. Impairment is measured as the amount by which 
the asset's carrying amount exceeds the fair value.

GOODWILL AND OTHER INTANGIBLE ASSETS
Goodwill is recognized as the excess cost of an acquired entity over the net amount assigned to assets acquired and 
liabilities assumed. Goodwill is not amortized, but rather tested for impairment on an annual basis and more often if 
circumstances require. Impairment losses are recognized whenever the carrying value of a reporting unit exceeds its 
fair value. See Note 4 to the Financial Statements.

The Company recognizes an acquired intangible apart from goodwill whenever the intangible arises from contractual 
or other legal rights, or whenever it can be separated or divided from the acquired entity and sold, transferred, licensed,

rented or exchanged, either individually or in combination with a related contract, asset or liability. Such intangibles 
are  amortized  over  their  estimated  useful  lives  (approximately  7  to  22  years)  unless  the  estimated  useful  life  is 
determined to be indefinite. The straight-line method of amortization is used as it has been determined to approximate 
the use pattern of the asset. The Company also maintains intangible assets with indefinite lives that are not amortized. 
These intangibles are tested for impairment on an annual basis and more often if circumstances require. An impairment 
loss is recognized whenever the estimated fair value of the asset is less than its carrying value. See Note 4 to the 
Financial Statements.

The Company capitalizes certain costs related to the purchase and development of internal-use software.  Amortization 
of capitalized software is on a straight-line basis over three or five years. 

FAIR VALUE OF FINANCIAL INSTRUMENTS
The carrying amounts of cash and cash equivalents, receivables and accounts payable approximate fair value due to 
the short-term nature of these financial instruments. See Note 9 to the Financial Statements for fair value of long-term 
debt.  

CONTINGENCIES
The Company accrues for costs relating to litigation claims and other contingent matters, when it is probable that a 
liability has been incurred and the amount of the assessment can be reasonably estimated.

NEW ACCOUNTING STANDARDS

In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other 
Comprehensive Income. This ASU allows a reclassification from AOCE to Retained earnings for stranded tax effects 
resulting from the 2017 Tax Cuts and Jobs Act. The effective date of this ASU is for fiscal years and interim periods 
beginning after December 15, 2018, and early adoption is permitted. The Company has evaluated the provisions of 
this standard and elected to early implement and reclassify $15 million of income tax effects related to the change in 
the U.S. federal corporate income tax rate from AOCE to Retained earnings. See Note 14 to the Financial Statements. 

In August 2018, the FASB issued ASU 2018-14, Retirement Benefits - Defined Benefit Plans - Changes to the Disclosure 
Requirements for Defined Benefit Plans. This ASU removes disclosures that are no longer considered cost-beneficial, 
clarifies specific requirements of the disclosure and adds disclosure requirements identified as relevant to improve the 
effectiveness of the disclosures. The effective date of this ASU is for fiscal years and interim periods beginning after 
December 15, 2020, and early adoption is permitted. The Company elected to early adopt this ASU and the related 
disclosure changes are reflected in Note 10 to the Financial Statements.  

In September 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other Internal Use Software (Subtopic 
350-40) Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service 
Contract.  This ASU aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement 
that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain 
internal-use software. The effective date of this ASU is for fiscal years and interim periods beginning after December 
15, 2019,  and early  adoption  is permitted. The  Company  elected  to  early adopt  during  the  fourth  quarter  of 2018 
prospectively, with no material impact to the Company's Consolidated Financial Statements.

LEASE ACCOUNTING STANDARDS

In  February  2016,  the  FASB  issued ASU  2016-02,  Leases  as  modified  subsequently  by ASUs  2018-01,  2018-10, 
2018-11 and 2018-20 (Topic 842). The core principle of the ASU improves transparency and comparability related to 
the accounting and reporting of leasing arrangements, including balance sheet recognition for assets and liabilities 
associated with rights and obligations created by leases with terms greater than twelve months, among other changes. 

The  effective  date  of  these ASUs  is  for  fiscal  years  and  interim  periods  beginning  after  December  15,  2018. The 
Company adopted the new guidance on January 1, 2019, utilizing the modified retrospective transition method that 
allows for a cumulative-effect adjustment in the period of adoption, and does not plan to restate prior periods. Additionally, 
the Company elected certain practical expedients permitted under the transition guidance.

Upon adoption, the Company's rights of use assets and corresponding lease liabilities are estimated at approximately 
$210 million to $230 million before considering deferred taxes. These amounts represent 4% and 6% of the Company’s 

49

 
 
Total assets and Total liabilities, respectively. Grainger does not expect a material impact to the Company’s Consolidated 
Statements of Earnings, Comprehensive Earnings or Cash Flows. 

NOTE 2 - REVENUE 

Company revenue is primarily comprised of MRO product sales and related activities, such as freight and services.

Grainger serves a large number of customers in diverse industries, which are subject to different economic and market 
specific factors. The Company's presentation of revenue by industry most reasonably depicts how the nature, amount, 
timing and uncertainty of Company revenue and cash flows are affected by economic and market specific factors. The

Grainger tests reporting units’ goodwill and intangible assets for impairment annually during the fourth quarter and 
more frequently if impairment indicators exist. Grainger periodically performs qualitative assessments of significant 
events  and  circumstances,  such  as  reporting  units'  historical  and  current  results,  assumptions  regarding  future 
performance, strategic initiatives and overall economic factors to determine the existence of impairment indicators and 
assess if it is more likely than not that the fair value of the reporting unit or indefinite-lived intangible assets is less than 
its carrying value and if a quantitative impairment test is necessary. In the quantitative test, Grainger compares the 
carrying value of the reporting unit or an indefinite-lived intangible asset with its fair value. Any excess of the carrying 
value over fair value is recorded as an impairment charge.

The fair value of reporting units is calculated primarily using the discounted cash flow (DCF) method and utilizing value 
indicators from a market approach to evaluate the reasonableness of the resulting fair values. Estimates of market-
participant risk-adjusted weighted average cost of capital are used as a basis for determining the discount rates to 
apply to the reporting units’ future expected cash flows and terminal value.

Grainger’s indefinite-lived intangibles are primarily trade names. The fair value of trade names is calculated primarily 
using the relief from royalty method, which estimates the expected royalty savings attributable to the ownership of the 
trade name asset. The key assumptions when valuing a trade name are the revenue base, the royalty rate and the 
discount rate.

During the quarter ended September 30, 2018, the Company identified impairment indicators at the Cromwell reporting 
unit.  In  the  quantitative  goodwill  impairment  test  performed  in  2017,  the  fair  value  of  the  Cromwell  reporting  unit 
exceeded its carrying value by 15%. However, its operating performance deteriorated during 2018 and the Company 
lowered its short-term forecasts and long-term outlook projections. These factors, combined with sustained economic 
uncertainty in the U.K. market and higher interest rates, led the Company to conclude that it was more likely than not 
that the carrying value of Cromwell’s goodwill and intangible assets may not be recoverable. Accordingly, a quantitative 
test was performed during the quarter ended September 30, 2018.

The Company considered the impact of the prolonged softness and uncertainty in the U.K. market due to Brexit and 
other unfavorable structural economic conditions, as well as Cromwell’s underperformance compared to expectations, 
prior  year  quantitative  test  assumptions  and  future  performance  projections.  The  revised  outlook  and  uncertainty 
beyond 2018 were factored into lower revenues, earnings and cash flow projections which, combined with an increase 
in  the  discount  rate,  resulted  in  the  calculated  fair  value  of  the  Cromwell  reporting  unit  below  its  carrying  value. 
Accordingly, the Company recorded a full goodwill impairment charge of $105 million with no tax benefit due to the 
nondeductibility of goodwill for tax purposes. The revised revenue and gross margin projections also resulted in the 
reduction of royalty rate and value attributable to the Cromwell trade name for which the Company recorded a $34 
million impairment charge during the same period.

The impairment charges related to Cromwell goodwill and trade name were recorded in other businesses in SG&A. 
The Company also performed an impairment test on Cromwell’s intangible assets subject to amortization and long-
lived assets using the undiscounted cash flows method and no impairment charge was required.

Grainger performed its annual impairment testing in the fourth quarter. The testing included a qualitative assessment 
of all other reporting units' goodwill and intangible assets. The Company concluded that it was not more likely than 
not that the fair value of the reporting unit of indefinite-lived intangible assets is less than its carrying value.

The risk of potential failure of future impairment tests is highly dependent upon a number of assumptions. Changes 
in assumptions regarding discount rate and future performance, as well as the ability to execute on growth initiatives 
and productivity improvements, may have a significant impact on future cash flows. Likewise, unfavorable economic 
environment and changes in market conditions or other factors may result in future impairments of the goodwill and 
intangible assets.

Inventories primarily consist of merchandise purchased for resale.  Inventories would have been $394 million and $382 
million higher than reported at December 31, 2018 and December 31, 2017, respectively, if the FIFO method of inventory 
accounting had been used for all the Company inventories. Net earnings would have increased by $8 million, and 
decreased by $1 million and $3 million for the years ended December 31, 2018, 2017 and 2016, respectively, using

Senior Notes
In May 2017, the Company issued $400 million of unsecured 4.20% Senior Notes that mature on May 15, 2047. A 
portion of the proceeds from this bond issuance was used to pay outstanding commercial paper during 2017. The 
4.20% Notes require no principal payments until the maturity date and interest is payable semi-annually on May 15 
and November 15. 

In May 2016, the Company issued $400 million of unsecured 3.75% Senior Notes that mature on May 15, 2046. The 
3.75% Notes require no principal payments until the maturity date and interest is payable semi-annually on May 15 
and November 15.

In June 2015, the Company issued $1 billion of unsecured 4.60% Senior Notes that mature on June 15, 2045. The 
4.60% Notes require no principal payments until the maturity date and interest is payable semi-annually on June 15
and December 15.

The Company may redeem the Senior Notes in whole at any time or in part from time to time at a “make-whole” 
redemption price prior to their respective maturity dates. The redemption price is calculated by reference to the then-
current yield on a U.S. treasury security with a maturity comparable to the remaining term of the Senior Notes plus 
20-25 basis points, together with accrued and unpaid interest, if any, at the redemption date. Additionally, if the Company 
experiences specific kinds of changes in control, it will be required to make an offer to purchase the Senior Notes at 
101% of their principal amount plus accrued and unpaid interest, if any, at the date of purchase. Within one year of 
the maturity date, the Company may redeem the Senior Notes in whole at any time or in part at 100% of their principal 
amount, together with accrued and unpaid interest, if any, to the redemption date. 

Costs  and  discounts  of  approximately $24  million associated  with  the  issuance  of  the  Senior  Notes,  representing 
underwriting fees and other expenses, have been recorded as a contra-liability within Long-term debt and are being 
amortized to interest expense over the term of the Notes.  

British Pound Term Loan
In August 2015, the Company entered into an unsecured credit facilities agreement providing for a five-year term loan 
of £160 million and revolving credit facility of up to £20 million (see Note 8 to the Financial Statements). Under the 
agreement, the principal amount of the term loan will be repaid semiannually in installments of £4 million beginning 
February 2016 through February 2020 with the remaining outstanding amount due August 2020. At the election of the 
Company, the term loan bears interest at the LIBOR Rate plus a margin of 75 basis points, as defined within the term 

57

 
loan agreement. At December 31, 2018, the Company had elected a one-month LIBOR interest period. The weighted 
average interest rate was 1.34% and 1.04% for the years ended December 31, 2018 and 2017, respectively. 

Euro Term Loan 
On August 31, 2016, the Company entered into an agreement for a five-year term loan of €1 10 million and a revolving 
credit facility of up to €20  million (see Note 8 to the Financial Statements). The proceeds from the term loan were used 
to pay in full €102.5  million of a term loan that matured in August 2016. Under the agreement, no principal amount of 
the loan will be required to be paid until the loan becomes due on August 31, 2021, at which time the loan will be 
required to be paid in full. The Company, at its option, may prepay this term loan in whole or in part at the end of any 
interest period without penalty. The loan bears interest at the EURIBOR plus a margin of 45 basis points, as defined 
within the term loan agreement. If EURIBOR is less than zero, then EURIBOR will be deemed to be zero. The interest 
rate at both December 31, 2018 and 2017 was 0.45%. 

Canadian Dollar Revolving Credit Facility
In September 2014, the Company entered into an unsecured revolving credit facility with a maximum availability of    
C$175 million. The loan bears interest at the Canadian Dollar Offered Rate (CDOR) plus a margin of 80 basis points, 
as defined within the loan agreement. The weighted average interest rate during the year on this outstanding amount 
was 2.50%. No principal payments are required on the credit facility until the maturity date.  The facility matures in 
2019 and accordingly, the amount outstanding is included in Current maturities of long-term debt as of December 31, 
2018. 

The  estimated fair  value of  the  Company’s  senior  notes  was  based  on  available  external  pricing  data  and  current 
market rates for similar debt instruments, among other factors, which are classified as level 2 inputs within the fair 
value hierarchy. The carrying value of other long-term debt approximates fair value due to their variable interest rates.

The scheduled aggregate principal payments related to long-term debt, excluding debt issuance costs, are due as

The Company's long-term debt instruments include affirmative and negative covenants that are usual and customary 
for companies with similar credit ratings and do not contain any financial performance covenant. The Company was 
in compliance with all debt covenants as of December 31, 2018.

NOTE 10 - EMPLOYEE BENEFITS

The Company provides various retirement benefits to eligible employees, including contributions to defined contribution 
plans,  pension  benefits  associated  with  defined  benefit  plans,  postretirement  medical  benefits  and  other  benefits.  
Eligibility requirements and benefit levels vary depending on employee location. Various foreign benefit plans cover 
employees in accordance with local legal requirements.

Defined Contribution Plans
A majority of the Company's U.S. employees are covered by a noncontributory profit-sharing plan. The plan aligns 
Company contributions to Company performance and includes two components, a variable annual contribution based 
on a rate of return on invested capital and an automatic contribution equal to 3% of total eligible compensation. In 
addition, employees covered by the plan are also able to make personal contributions. The total Company contribution 
will be maintained at a minimum of 8% and a maximum of 18% of total eligible compensation paid to eligible employees. 
The  total  profit-sharing  plan  expense  was  $164  million,  $120  million  and  $84  million  for  2018,  2017  and  2016, 
respectively. 

58

The Company sponsors additional defined contribution plans available to certain U.S. and foreign employees for which 
contributions are made by the Company and participating employees. The expense associated with these defined 
contribution plans totaled $13 million, $18 million, and $12 million for 2018, 2017 and 2016, respectively.

Defined Benefit Plans and Other Retirement Plans
The Company sponsors defined benefit plans available to certain foreign employees. The cost of these programs is 
not significant to the Company. In certain countries, pension contributions are made to government-sponsored social 
security pension plans in accordance with local legal requirements. For these plans, the Company has no continuing 
obligations other than the payment of contributions.

Postretirement Healthcare Benefits Plans
The Company has a postretirement healthcare benefits plan that provides coverage for a majority of its U.S. employees 
hired prior to January 1, 2013, and their dependents should they elect to maintain such coverage upon retirement. 
Covered employees become eligible for participation when they qualify for retirement while working for the Company. 
Participation in the plan is voluntary and requires participants to make contributions toward the cost of the plan, as 
determined by the Company.

During the third quarter of 2017, the Company implemented plan design changes effective January 1, 2018, for the 
post-65 age group. This plan change moved all post-65 Medicare eligible retirees to healthcare exchanges and provided 
them a subsidy to purchase insurance. The amount of the subsidy is based on years of service. As a result of the plan 
change, the plan obligation was remeasured as of August 31, 2017. The remeasurement resulted in a decrease in the 
postretirement  benefit  obligation  of  $76  million  and  a  corresponding  unrecognized  gain  recorded  in  Other 
comprehensive earnings net of tax of $29 million. 

The net periodic costs, as previously reported in the 2017 and 2016 Financial Statements, have been reclassified to 
conform to the 2018 presentation in accordance with ASU 2017-07. The net periodic benefits costs were valued with 
a  measurement  date  of  January  1  for  each  year  and August  31,  2017  remeasurement  date  and  consisted  of  the 
following components (in millions of dollars):

The Company has elected to amortize the amount  of net unrecognized gains  over a period equal to the average 
remaining service period for active plan participants expected to retire and receive benefits of approximately 12.9 years 
for 2018.

The postretirement benefit obligation was determined by applying the terms of the plan and actuarial models.  These 
models  include  various  actuarial  assumptions,  including  discount  rates,  long-term  rates  of  return  on  plan  assets, 
healthcare cost trend rate and cost-sharing between the Company and the retirees. The Company evaluates its actuarial 
assumptions on an annual basis and considers changes in these long-term factors based upon market conditions and 
historical experience.

The discount rate assumptions reflect the rates available on high-quality fixed income debt instruments as of December 
31, the measurement date of each year.  These rates have been selected due to their similarity to the duration of the 
projected cash flows of the postretirement healthcare benefit plan.  As of December 31, 2018, the Company increased 
the discount rate from 3.44% to 4.08% to reflect the increase in the market interest rates at December 31, 2018.  

As of December 31, 2018, the Company changed the mortality improvement table used to project mortality rates into 
the future from Mortality Table RPH-2014 with Mortality Improvement Scale MP 2016 to Mortality Table RPH-2014 with 
Mortality Improvement Scale MP 2018, which was published by the Society of Actuaries and reflects the most recent 
updates to life expectancies. RPH-2014 Table is a headcount weighted table, which is also more appropriate for a 
postretirement healthcare benefit plan. 

The Company reviews external data and its own historical trends for healthcare costs to determine the healthcare cost 
trend rates. As of December 31, 2016, Grainger adopted a new healthcare trend rate to include a pre and post age 
65 trend rates. Post age 65, prescription drug costs, primarily specialty drugs, are expected to increase the cost of 
healthcare more significantly than medical expenses. The alternative trend rates allow for a better estimate of expected 
costs for this plan.  As of December 31, 2018, the initial healthcare cost trend rate was 6.31% for pre age 65.  The 
healthcare costs trend rates decline each year until reaching the ultimate trend rate of 4.50%. The plan amendment 
adopted in 2017 moves all post age 65 Medicare eligible retirees to an exchange and provides a subsidy to those 
retirees to purchase insurance. The amount of the subsidy is based on years of service and is indexed at 2.50% for 
grandfathered employees. 

The Company has established a Group Benefit Trust (Trust) to fund the plan obligations and process benefit payments.  
All assets of the Trust are invested in equity funds designed to track to either the Standard & Poor's 500 Index (S&P 
500) or the Total International Composite Index.  The Total International Composite Index tracks non-U.S. stocks within 
developed and emerging market economies.  This investment strategy reflects the long-term nature of the plan obligation 
and seeks to take advantage of the earnings potential of equity securities in the global markets and intends to reach 
a balanced allocation between U.S. and non-U.S. equities. The plan's assets are stated at fair value, which represents 

61

the net asset value of shares held by the plan in the registered investment companies at the quoted market prices 
(level 1 input). The plan assets available for benefits are net of Trust liabilities, primarily related to deferred income 
taxes and taxes payable at December 31 (in millions of dollars):

The Company uses the long-term historical return on the plan assets and the historical performance of the S&P 500 
and the Total International Composite Index to develop its expected return on plan assets. The after-tax expected long-
term rates of return on plan assets of 7.13% at December 31, 2018 is based on the historical average of long-term 
rates of return and an estimated tax rate. The required use of an expected long-term rate of return on plan assets may 
result in recognition of income that is greater or lower than the actual return on plan assets in any given year. Over 
time, however, the expected long-term returns are designed to approximate the actual long-term returns and, therefore, 
result in a pattern of income recognition that more closely matches the pattern of the services provided by the employees.

The Company's investment policies include periodic reviews by management and trustees at least annually concerning: 
(1) the allocation of assets among various asset classes (e.g., domestic stocks, international stocks, short-term bonds, 
long-term  bonds,  etc.);  (2)  the  investment  performance  of  the  assets,  including  performance  comparisons  with 
appropriate benchmarks; (3) investment guidelines and other matters of investment policy and (4) the hiring, dismissal 
or retention of investment managers.

The funding of the Trust is an estimated amount that is intended to allow the maximum deductible contribution under 
the Internal Revenue Code of 1986 (IRC), as amended. There are no minimum funding requirements and the Company 
intends to follow its practice of funding the maximum deductible contribution under the IRC. 

The Company forecasts the following benefit payments related to postretirement (which include a projection for 
expected future employee service) for the next ten years (in millions of dollars):

NOTE 11 - LEASES

The Company leases certain land, buildings, equipment and vehicles under noncancelable operating leases that expire 
at various dates through 2036. Many of the building leases obligate the Company to pay real estate taxes, insurance 
and certain maintenance costs and contain multiple renewal provisions, exercisable at the Company's option. Leases 
that contain predetermined fixed escalations of the minimum rentals are recognized in rental expense on a straight-
line basis over the lease term. Cash or rent abatements received upon entering into certain operating leases are also 
recognized on a straight-line basis over the lease term. 

62

At  December  31,  2018  the  approximate  future  minimum  lease  payments  for  operating  leases  were  as  follows  (in

In the fourth quarter of 2018, Grainger consolidated three office locations into one main location in the Chicago area, 
which increased the future minimum lease payments by $48 million and sublease income by $6 million. The new lease  
has a 10-year term.

Rent expense was $76 million, $76 million and $81 million for 2018, 2017 and 2016, respectively. These amounts are 
net of sublease income of $3 million, $2 million and $2 million for 2018, 2017 and 2016. 

Capital leases as of December 31, 2018 are not considered material. Capital lease obligations are reported in Long-
term debt.

Effective January 1, 2019, the Company implemented ASU 2016-02, Leases and subsequent modifications ASUs 
2018-01, 2018-10, 2018-11 and 2018-20. See Note 1 to the Financial Statements for more information.

NOTE 12 - STOCK INCENTIVE PLANS

The Company maintains stock incentive plans under which the Company may grant a variety of incentive awards to 
employees  and  executives,  which  include  restricted  stock  units  (RSUs),  non-qualified  stock  options,  performance 
shares and deferred stock units. As of December 31, 2018, there were 2.5 million shares available for grant under the 
plans. When awards are exercised or settled, shares of the Company’s treasury stock are issued.

Pretax stock-based compensation expense, included in SG&A was $47 million, $33 million and $36 million in 2018, 
2017 and 2016, respectively and was primarily comprised of Restricted Stock Units (RSUs) and option grants. Related 
income tax benefits recognized in earnings were $26 million, $26 million and $12 million in 2018, 2017 and 2016, 
respectively.

63

Restricted Stock Units
The Company awards RSUs to certain employees and executives. RSUs granted vest generally over periods from 
three to seven years from issuance, although accelerated vesting is provided in certain instances. Holders of RSUs 
are entitled to receive nonforfeitable cash payments equivalent to cash dividends and other distributions paid with 
respect to common stock. RSUs are settled by the issuance of the Company's common stock on a one-for-one basis. 
Compensation expense related to RSUs is based upon the closing market price on the last trading day preceding the 
date of award and is charged to earnings on a straight-line basis over the vesting period. The following table summarizes 
RSU activity (in millions, except for share and per share amounts):

The Company uses a binomial lattice option pricing model for the valuation of stock options. The weighted average 
fair value of options granted in 2018, 2017 and 2016 was $67.31, $45.09 and $44.94, respectively. The fair value of 
options granted in 2018, 2017 and 2016 used the following assumptions:

Risk-free interest rate

The risk-free interest rate is selected based on yields from U.S. Treasury zero-coupon issues with a remaining term 
approximately equal to the expected term of the options being valued. The expected life selected for options granted 
during each year presented represents the period of time that the options are expected to be outstanding based on 
historical data of option holder exercise and termination behavior. Expected volatility is based upon implied and historical 
volatility of the Company's closing stock price over a period equal to the expected life of each option grant. Historical 
Company information is the primary basis for selection of expected dividend yield assumptions.

At December 31, 2018 the Company had $269 million of net operating loss (NOLs) carryforwards related primarily to 
foreign operations. Some of the operating loss carryforwards may expire at various dates through 2038. The Company 
has recorded a valuation allowance, which represents a provision for uncertainty as to the realization of the tax benefits 
of these carryforwards and deferred tax assets that may not be realized. The Company's valuation allowance changed 
as follows (in millions of dollars):

In 2015 and 2016, the Company acquired noncontrolling interests in limited liability companies established to produce 
refined coal. The production and sale of refined coal that results in required emission reductions is eligible for tax 
credits under Section 45 of the Internal Revenue Code. The Company received tax credits in proportion to its equity 
interest. During the second half of 2018, the Company concluded its investments and will not have future benefits from 
these interests. 

U.S. Tax Legislation

On December 22, 2017, the Tax Cuts and Jobs Act (the Tax Act) was signed into law, which significantly revised the 
U.S. corporate income tax system by lowering federal corporate income tax rates from 35% to 21% effective January 
1,  2018,  allowing  accelerated  expensing  of  qualified  capital  investments  for  a  specific  period,  limiting  net  interest 
expense deductions and transitioning U.S. international taxation from a worldwide to a territorial tax system that required 
a one-time transition tax on unremitted earnings of certain foreign subsidiaries that were previously tax deferred, among 
other changes. 

During 2018, the Company completed the accounting for the impact from the Tax Act. The Company determined that 
there was no material change from its estimate recorded on December 31, 2017.

69

Accounting for Income Taxes on Global Intangible Low-Taxed Income (GILTI)

The Company recognizes the tax on GILTI as a period expense in the period the tax is incurred. Under this policy, the 
Company  has  not  provided  deferred  taxes  related  to  temporary  differences  that  upon  their  reversal  will  affect  the 
amount of income subject to GILTI in the period. 

Foreign Undistributed Earnings 

Estimated gross undistributed earnings of foreign subsidiaries at December 31, 2018, amounted to $545 million. The 
Company considers these undistributed earnings permanently reinvested in its foreign operations and is not recording 
a deferred tax liability for any foreign withholding taxes on such amounts. The Company's permanent reinvestment 
assertion has not changed following the enactment of the Tax Act. If at some future date the Company ceases to be 
permanently reinvested in its foreign subsidiaries, the Company may be subject to foreign withholding and other taxes 
on these undistributed earnings and may need to record a deferred tax liability for any outside basis difference in its 
investments in its foreign subsidiaries.

Tax Uncertainties

The Company recognizes in the financial statements a provision for tax uncertainties, resulting from application of 
complex tax regulations in multiple tax jurisdictions. The changes in the liability for tax uncertainties, excluding interest, 
are as follows (in millions of dollars):

For the Years Ended December 31,

2018

2017

2016

Balance at beginning of year

Additions for tax positions related to the current year
Additions for tax positions of prior years
Reductions for tax positions of prior years

The Company classifies the liability for tax uncertainties in deferred income taxes and tax uncertainties. Included in 
this amount are $13 million and $21 million at December 31, 2018 and 2017, respectively, of tax positions for which 
the ultimate deductibility is highly certain but for which there is uncertainty about the timing of such deductibility. Any 
changes in the timing of deductibility of these items would not affect the annual effective tax rate but would accelerate 
the payment of cash to the taxing authorities to an earlier period. Excluding the timing items, the remaining amounts 
would  affect the  annual  tax rate.  In 2018, the changes  to  tax  positions  related  generally  to  the  impact of  expiring 
statutes, conclusion of audits and audit settlements. 

The Company regularly undergoes examination of its federal income tax returns by the Internal Revenue Service. The 
statute of limitations expired for the Company's 2014 federal tax return. The tax years 2015 through 2018 are open. 
The Company is also subject to audit by state, local and foreign taxing authorities. Tax years 2009-2018 remain subject 
to state and local audits and 2007-2018 remain subject to foreign audits. The amount of liability associated with the 
Company's tax uncertainties may change within the next 12 months due to the pending audit activity, expiring statutes 
or tax payments. A reasonable estimate of such change cannot be made. 

The Company recognizes interest expense and penalties related to its tax uncertainties in the provision for income 
taxes. For the years ended December 31, 2018, 2017 and 2016, the Company recognized an expense of approximately 
$1 million for each year. Total accrued interest and penalties related to tax uncertainties as of December 31, 2018, 
2017 and 2016, were approximately $4 million, $5 million and $4 million, respectively.

NOTE 16 - EARNINGS PER SHARE 

Certain stock incentive plans grant stock awards that contain nonforfeitable rights to dividends meet the criteria of a 
participating security. Under the two-class method, earnings are allocated between common stock and participating 
securities. The presentation of basic and diluted earnings per share is required only for each class of common stock 
and not for participating securities. As such, the Company presents basic and diluted earnings per share for its one 
class of common stock.

The two-class method includes an earnings allocation formula that determines earnings per share for each class of 
common stock according to dividends declared and undistributed earnings for the period. The Company’s reported 
net  earnings  are  reduced  by  the  amount  allocated  to  participating  securities  to  arrive  at  the  earnings  allocated  to 
common stock shareholders for purposes of calculating earnings per share. 

The dilutive effect of participating securities is calculated using the more dilutive of the treasury stock or the two-class 
method. The Company has determined the two-class method to be the more dilutive. As such, the earnings allocated 
to common stock shareholders in the basic earnings per share calculation is adjusted for the reallocation of undistributed 
earnings to participating securities to arrive at the earnings allocated to common stock shareholders for calculating 
the diluted earnings per share.

The following table sets forth the computation of basic and diluted earnings per share under the two-class method (in 
millions of dollars, except for share and per share amounts):

NOTE 17 - SEGMENT INFORMATION

Grainger’s two reportable segments are the U.S. and Canada. The U.S. reportable segment reflects the results of 
Grainger's U.S. businesses. The Canada reportable segment reflects the results for Acklands-Grainger, Inc. and its 
subsidiaries. Other businesses include the endless assortment (single-channel online businesses), Zoro Tools, Inc. 
(Zoro)  in  the  U.S.  and  MonotaRO  Co.  (MonotaRO)  in  Japan,  and  smaller  high-tough,  high-service  businesses  in 
Europe, Asia and Mexico. These businesses individually do not meet the criteria of a reportable segment. Operating 
segments generate revenue almost exclusively through the distribution of MRO supplies, as service revenues account 
for approximately 1% of total revenues for each operating segment.

The accounting policies of the segments are the same as those described in the summary of significant accounting 
policies. Intersegment transfer prices are established at external selling prices, less costs not incurred due to a related 
party sale. The segment results include certain centrally incurred costs for shared services that are charged to the 
segments based upon the relative level of service used by each operating segment.

Unallocated  expenses  and  eliminations  primarily  relate  to  the  Company's  headquarters  support  services  and 
intercompany eliminations, which are not part of any reportable segment. Unallocated expenses include supply chain, 
product management and procurement, finance, communications, human resources, information systems, legal and 
compliance, internal audit and real estate. These services are provided in varying degrees to all businesses.

The Company is a broad-line distributor of MRO products and services. Products are regularly added and deleted 
from the Company's inventory. Accordingly, it would be impractical to provide sales information by product category 
due to the way the business is managed.

Assets for reportable segments include net accounts receivable and first-in, first-out inventory which are reported to 
the Company's Chief Operating Decision Maker. Other current and non-current assets include all other assets of the 
reportable segments. Unallocated assets are primarily comprised of non-operating cash and cash equivalents, property, 
buildings and equipment, net, and certain prepaid expenses related to the Company's headquarters support services.

Depreciation  and  amortization  presented  above  includes  depreciation  of  long-lived  assets  and  amortization  of 
capitalized software.

NOTE 18 - CONTINGENCIES AND LEGAL MATTERS

From time to time the Company is involved in various legal and administrative proceedings that are incidental to its 
business, including claims related to product liability, general negligence, contract disputes, environmental issues, 
unclaimed property, wage and hour laws, intellectual property, employment practices, regulatory compliance or other 
matters  and  actions  brought  by  employees,  consumers,  competitors,  suppliers  or  governmental  entities.  As  a 
government  contractor  selling  to  federal,  state  and  local  governmental  entities,  the  Company  is  also  subject  to 
governmental or regulatory inquiries or audits or other proceedings, including those related to contract administration 
or to pricing compliance. It is not expected that the ultimate resolution of any of these matters will have, either individually 
or in the aggregate, a material adverse effect on the Company's consolidated financial position or results of operations.

From time to time, the Company has also been named, along with numerous other nonaffiliated companies, as a 
defendant  in  litigation  in  various  states  involving  asbestos  and/or  silica.  These  lawsuits  typically  assert  claims  of 
personal injury arising from alleged exposure to asbestos and/or silica as a consequence of products manufactured 
by third parties purportedly distributed by the Company. While several lawsuits have been dismissed in the past based 
on the lack of product identification, if a specific product distributed by the Company is identified in any pending or 
future lawsuits, the Company will seek to exercise indemnification remedies against the product manufacturer to the 
extent available. In addition, the Company believes that a substantial number of these claims are covered by insurance. 
The Company has entered into agreements with its major insurance carriers relating to the scope and coverage and 
the costs of defense, of lawsuits involving claims of exposure to asbestos. The Company believes it has strong legal 
and factual defenses and intends to continue defending itself vigorously in these lawsuits. While the Company is unable 
to predict the outcome of these proceedings, it believes that the ultimate resolution will not have, either individually or 
in the aggregate, a material adverse effect on the Company’s consolidated financial position or results of operations.

FORWARD-LOOKING STATEMENTS

From time to time, in this Annual Report on Form 10-K, as well as in other written reports, communications and verbal statements, 
Grainger makes forward-looking statements that are not historical in nature but concern forecasts of future results, business plans, 
analyses, prospects, strategies, objectives and other matters that may be deemed to be “forward-looking statements” under the federal 
securities laws. Forward-looking statements can generally be identified by their use of terms such as “anticipate,” “estimate,” “believe,” 
“expect,” “could,” “forecast,” “may,” “intend,” “plan,” “predict,” “project,” “will,” or “would” and similar terms and phrases, including 
references to assumptions.

Grainger cannot guarantee that any forward-looking statement will be realized and achievement of future results is subject to risks and 
uncertainties, many of which are beyond the Company’s control, which could cause Grainger’s results to differ materially from those that 
are presented.

Important factors that could cause actual results to differ materially from those presented or implied in the forward- looking statements 
include, without limitation: higher product costs or other expenses; a major loss of customers; loss or disruption of sources of supply; 
increased competitive pricing pressures; failure to develop or implement new technology initiatives or business strategies; failure to 
adequately protect intellectual property or successfully defend against infringement claims; the implementation, timing and results of 
the Company’s strategic pricing initiatives and other responses to market pressures; the outcome of pending and future litigation or 
governmental or regulatory proceedings, including with respect to wage and hour, anti-bribery and corruption, environmental, advertising, 
privacy and cybersecurity matters; investigations, inquiries, audits and changes in laws and regulations; disruption of information 
technology or data security systems; general industry, economic, market or political conditions; general global economic conditions; 
currency exchange rate fluctuations; market volatility, including volatility or price declines of the Company’s common stock; commodity 
price volatility; labor shortages; facilities disruptions or shutdowns; higher fuel costs or disruptions in transportation services; natural 
and other catastrophes; unanticipated and/or extreme weather conditions; loss of key members of management; the Company’s ability 
to operate, integrate and leverage acquired businesses; changes in effective tax rates and other factors identified under Item 1A: Risk 
Factors and elsewhere in this Form 10-K.

Caution should be taken not to place undue reliance on Grainger’s forward-looking statements and Grainger undertakes no obligation 
to update or revise any of its forward-looking statements, whether as a result of new information, future events or otherwise, except as 
required by law.

For a list of factors that could cause Grainger’s results to differ materially from those that are presented, please see Item 7: Management’s 
Discussion and Analysis of Financial Condition and Results of Operations, other factors identified under Item 1A: Risk Factors and 
elsewhere in Grainger’s Annual Report on Form 10-K.
