PART I

Item 1: Business

The Company

W.W. Grainger, Inc., incorporated in the State of Illinois in 1928, is a broad-line distributor of maintenance, repair and operating (MRO) supplies and other related products and services used by businesses and institutions primarily in the United States and Canada, with a presence in Europe, Asia and Latin America. In this report, the words “Grainger” or “Company” mean W.W. Grainger, Inc. and its subsidiaries.

Grainger uses a multichannel business model to provide customers with a range of options for finding and purchasing products, utilizing sales representatives, direct marketing materials, catalogs and eCommerce. Grainger serves more than 2 million customers worldwide through a network of highly integrated branches, distribution centers, websites and export services.

In 2013, Grainger acquired two businesses in the United States. E&R Industrial Sales, Inc., acquired in the third quarter, is a distributor of metalworking, production supplies and MRO materials to manufacturers and industrial customers. Safety Solutions, Inc., acquired in the fourth quarter, is a distributor of safety footwear, supplies and services with a strong focus on the manufacturing sector.

In 2013, Grainger divested four direct marketing brands at the end of the fourth quarter, which included Gempler's, Ben Meadows, AW Direct and McFeely's.

Grainger has centralized business support functions that provide coordination and guidance in the areas of accounting and finance, business development, communications and investor relations, compensation and benefits, information systems, health and safety, global supply chain functions, human resources, risk management, internal audit, legal, real estate, security, tax and treasury. These services are provided in varying degrees to all business units.

Items are regularly added to and deleted from Grainger’s product lines on the basis of customer demand, market research, recommendations of suppliers, sales volumes and other factors.

Grainger’s two reportable segments are the United States and Canada and they are described further below. Other businesses include operations in Europe, Asia, Latin America and other U.S. operations. These businesses generate revenue through the distribution of maintenance, repair and operating supplies and products and provide related services. For segment and geographical information and consolidated net sales and operating earnings, see “Item 7: Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Note 16 to the Consolidated Financial Statements.

United States

The United States business offers a broad selection of maintenance, repair and operating supplies and other related products and services through local branches, sales representatives, catalogs and eCommerce. A combination of product breadth, local availability, speed of delivery, detailed product information and competitively priced products and services is provided by this business. Products offered include material handling equipment, safety and security supplies, lighting and electrical products, power and hand tools, pumps and plumbing supplies, cleaning and maintenance supplies, building and home inspection supplies, vehicle and fleet components and many other items primarily focused on the facilities maintenance market. Services offered primarily include inventory management and energy efficiency solutions.

The United States business operates in all 50 states through a network of 390 branches and sales representatives. The branches are located in close proximity to the majority of U.S. businesses and serve the immediate needs of customers in their local markets by allowing them to pick up items directly from the branches. The branch network has approximately 4,800 employees who primarily fulfill counter and will-call product purchases and provide customer service. An average branch is 22,000 square feet in size, has 12 employees and handles about 150 transactions per day. In the normal course of business, Grainger continually reviews the effectiveness of its branch network. In 2013, Grainger added 21 branches to its portfolio through the recent acquisitions as noted above.

The logistics network in the United States is comprised of 18 distribution centers (DCs) of various sizes. Automated equipment and processes in the larger DCs allow them to handle the majority of the customer shipping for next-day product availability and replenish the branches that provide same-day availability. In 2013, Grainger opened a 1 million square-foot and highly automated DC in the Chicago area.

Customers range from small and medium-sized businesses to large corporations, government entities and other institutions. They are primarily represented by purchasing managers or workers in facilities maintenance departments and service shops across a wide range of industries such as manufacturing, hospitality, transportation, government, retail, healthcare and education. Sales in 2013 were made to approximately 1.4 million customers averaging 109,000 daily transactions. No single customer accounted for more than 3% of total sales.

The business has a sales force of almost 3,100 professionals who help businesses and institutions select the right products to find immediate solutions to maintenance problems and to reduce operating expenses and improve cash flows. In 2013, Grainger continued to expand its sales force to facilitate growth with targeted segments and provide more specialized support.

Another area in which the United States business helps customers be more productive is through inventory management services. A comprehensive program called KeepStock® is an offering that includes vendor managed inventory, customer managed inventory and on-site vending machines. Grainger's KeepStock program currently provides services to more than 21,000 customers at approximately 55,000 unique customer installations.

Customers can also purchase products through Grainger.com®. Customers continue to migrate to online and electronic purchasing. eCommerce revenues were $2.5 billion in 2013, an increase of 16% versus 2012. Grainger.com provides access to approximately 1.2 million products and serves as a prominent channel for the United States business. Grainger.com provides real-time price and product availability and detailed product information, and offers advanced features such as product search and compare capabilities. For customers with sophisticated electronic purchasing platforms, Grainger utilizes technology that allows these systems to communicate directly with Grainger.com. In 2013, Grainger transitioned Grainger.com to a new web platform, launched a Spanish language website and introduced new applications for mobile devices. Customers can also purchase products through other branded websites.

The majority of the products sold by the United States business are well recognized national branded products. In addition, 22% of 2013 sales were private label items bearing Grainger’s registered trademarks, such as DAYTON® motors, power transmission, HVAC and material handling, SPEEDAIRE® air compressors, AIR HANDLER® air filtration equipment, TOUGH GUY® cleaning products, WESTWARD® tools, CONDOR® safety products and LUMAPRO® lighting products. Grainger has taken steps to protect these trademarks against infringement and believes that they will remain available for future use in its business. The United States business purchases products for sale from more than 2,700 key suppliers, most of which are manufacturers. Through a global sourcing operation, the business procures competitively priced, high-quality products produced outside the United States from approximately 400 suppliers. Grainger sells these items primarily under the private label brands listed above. No single supplier comprised more than 5% of total purchases and no significant difficulty has been encountered with respect to sources of supply.

The Grainger catalog, most recently issued in February 2014, offers approximately 590,000 facilities maintenance and other products, an increase of 20,000 from the prior year, and is used by customers to assist in product selection. Approximately 1.6 million copies of the catalog were produced. In addition, Grainger’s United States business issues targeted catalogs for its multiple branded products, as well as other marketing materials.

Grainger estimates the United States market for facilities maintenance and related products to be approximately $122 billion, of which Grainger’s share is approximately 6%.

Canada

Acklands – Grainger is Canada’s leading broad-line distributor of industrial and safety supplies. 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 Canadian business serves customers through 171 branches, sales and service representatives and 6 DCs across Canada. Acklands – Grainger distributes tools, fasteners, safety supplies, instruments, welding and shop equipment, and many other items. During 2013, approximately 15,200 sales transactions were completed daily. A comprehensive catalog, printed in both English and French, was most recently issued in February 2014. The catalog has more than 139,000 products and is used by customers to assist in product selection. In addition, customers can purchase products through Acklandsgrainger.com, a fully bilingual website. In 2013, Acklands – Grainger announced a large product expansion, adding 200,000 new products to its online offering and also began construction on a 500,000 square-foot distribution center in the Toronto area. Grainger estimates the Canadian market for facilities maintenance and related products to be approximately $14 billion, of which Acklands – Grainger’s share is approximately 8%.

Other Businesses

Included in other businesses are the operations in Europe, Asia, Latin America and other U.S. operations. The more significant businesses in this group, those with anticipated revenues of more than $100 million in 2014, are described below.

Fabory

Fabory is a European distributor of fasteners, tools and industrial supplies. Fabory is headquartered in Tilburg, the Netherlands, and has more than 100 locations in 14 countries. Customers have access to more than 100,000 products through a catalog and through Fabory.com. Grainger estimates the European market (in which Fabory has its primary operations) for facilities maintenance and related products to be approximately $39 billion, of which Grainger’s share is approximately 1%.

Japan

Grainger operates in Japan through its 51% interest in MonotaRO Co. MonotaRO provides small and mid-sized domestic businesses with products that help them operate and maintain their facilities. MonotaRO is a catalog and web-based direct marketer with approximately 84% of orders being conducted through Monotaro.com. MonotaRO has no branches or sales force and fulfills all orders from two DCs, which have approximately 120,000 stocked products. Grainger estimates the Japanese market for facilities maintenance and related products to be approximately $45 billion, of which Grainger’s share is approximately 1%.

Mexico

Grainger’s operations in Mexico provide local businesses with maintenance, repair and operating supplies and other related products primarily from Mexico and the United States. The business in Mexico distributes products through a network of branches and two DCs where customers have access to approximately 119,000 products through a Spanish-language catalog and through Grainger.com.mx. Grainger estimates the Mexican market for facilities maintenance and related products to be approximately $11 billion, of which Grainger’s share is approximately 1%.

Zoro Tools

Zoro Tools is an online distributor of MRO products serving U.S. businesses and consumers through its website Zorotools.com.  Zoro Tools offers a broad selection of approximately 400,000 items at single, competitive prices. Zoro Tools has no branches or sales force, and product is delivered through the Grainger U.S. supply chain.

Seasonality

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

Competition

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 Internet-based businesses. Grainger provides local product availability, a broad product line, sales representatives, competitive pricing, catalogs (which include product descriptions and, in certain cases, extensive technical and application data), and electronic and Internet commerce technology. Other services, such as inventory management and energy efficiency solutions to assist customers in lowering their total facilities maintenance costs, are also offered. Grainger believes that it can effectively compete with manufacturers on small orders, but manufacturers may have an advantage in filling large orders. There are several large competitors, although the majority of the market is served by small local and regional competitors.

Employees

As of December 31, 2013, Grainger had approximately 23,700 employees, of whom approximately 22,500 were full-time and 1,200 were part-time or temporary. Grainger has never had a major work stoppage and considers employee relations to be good.

Item 1A: Risk Factors

The following is a discussion of significant risk factors relevant to Grainger's business that could adversely affect its financial position or results of operations.

Weakness in the economy could negatively impact Grainger's sales growth. Economic and industry trends affect Grainger's business environments. Economic downturns can cause customers, both domestic and international, to idle or close facilities, delay purchases and otherwise reduce their ability to purchase Grainger's products and services as well as their ability to make full and timely payments. Thus, a significant or prolonged slowdown in economic activity in the United States, Canada or any other major world economy could negatively impact Grainger's sales growth and results of operations.

The facilities maintenance industry is highly fragmented, and changes in competition could result in a decreased demand for Grainger's products and services. 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 Internet-based businesses. Competitive pressures could adversely affect Grainger's sales and profitability.

Volatility in commodity prices may adversely affect operating 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. Increases in the price of fuel could also drive up transportation costs. Grainger's ability to pass on increases in costs depends on market conditions. The inability to pass along cost increases could result in lower operating margins. In addition, higher prices could impact demand for these products, resulting in lower sales volumes.

Unexpected product shortages could negatively impact customer relationships, resulting in an adverse impact on results of operations. Grainger's competitive strengths include product selection and availability. Products are purchased from approximately 5,000 key suppliers located in various countries around the world, no 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, such as economic downturns, political unrest, trade issues, etc., any of which could adversely affect a supplier's ability to manufacture or deliver products. If Grainger were 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 key vendors. In the event Grainger were 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 or product mix could cause the gross margin percentage to decline. From time to time, Grainger experiences changes in customer and product mix that effect gross margin. Changes in customer and product mix result primarily from business acquisitions, changes in customer demand, customer acquisitions, selling and marketing activities and competition. If rapid growth with large customers continues, Grainger will face pressure to maintain current gross margins, as this customer segment receives discounted pricing due to their higher sales volume. There can be no assurance that Grainger will be able to maintain historical gross margins in the future.

Disruptions in Grainger's supply chain could result in an adverse impact on results of operations. A disruption within Grainger's logistics or supply chain network, including damage, destruction and other events which would cause one or more of the distribution centers to become non-operational, could adversely affect Grainger's ability to deliver inventory in a timely manner, impair Grainger's ability to meet customer demand for products and result in lost sales or damage to Grainger's reputation. Such a disruption could adversely impact the results of operations.

6

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, including its websites, 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 and websites. 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 natural disasters, power losses, computer viruses, telecommunication failures and other problems. If critical information systems fail or otherwise become unavailable, among other things, Grainger's ability to process orders, maintain proper levels of inventories, collect accounts receivable and disburse funds could be adversely affected. Any such interruption of Grainger's information systems could also subject Grainger to additional costs.

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 confidential information that customers provide to, among other things, purchase products or services, enroll in promotional programs and register on the website. Grainger also acquires and retains information about suppliers and employees in the normal course of business. Despite instituted safeguards for the protection of such information, computer hackers may attempt to penetrate Grainger's or its vendors' information systems and, if successful, misappropriate confidential customer, supplier, employee or other business information. 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. 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 other persons, any of which could have an adverse effect on Grainger, its financial condition and results of operations. In addition, compliance with tougher privacy and information security laws and standards may result in significant additional expense due to increased investment in technology and the development of new operational processes.

Fluctuations in foreign currency have an effect on reported results of operations. Foreign currency exchange rates and fluctuations have an impact on sales, costs and cash flows from international operations, and could affect reported financial performance.

Acquisitions 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, both foreign and domestic, involve various inherent risks, such as uncertainties in assessing the value, strengths, weaknesses, liabilities and potential profitability of acquired companies. There is a risk of potential losses of key employees of an acquired business and of an inability to achieve identified operating and financial synergies anticipated to result from an acquisition. Additionally, problems could arise from the integration of the acquired business including unanticipated changes in the business or industry, or general economic conditions that affect the assumptions underlying the acquisition. Any one or more of these factors could cause Grainger to not realize the benefits anticipated to result from the acquisitions 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 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 operating results 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.

7

Grainger's business is subject to various government regulations. Grainger's business is subject to a wide array of laws and regulations in every jurisdiction where it operates, and compliance with these laws and regulations increases the cost of doing business. Grainger is subject to a variety of laws and regulations, including without limitation import and export requirements, the Foreign Corrupt Practices Act, tax laws (including U.S. taxes on foreign subsidiaries), foreign exchange controls and cash repatriation restrictions, data privacy requirements, regulations and potential expansion of regulations on suppliers regarding the sources of supplies or products, labor laws and anti-competition regulations, and is also subject to audits and inquiries in the ordinary course of business. As a government contractor selling to federal, state and local government entities, Grainger is also subject to a wide variety of additional laws and regulations. Changes to the legal and regulatory environments could increase the cost of doing business, and such costs may increase in the future as a result of changes in these laws and regulations or in their interpretation. Furthermore, Grainger has implemented policies and procedures designed to facilitate compliance with these laws and regulations, but there can be no assurance that employees, contractors or agents will not violate such laws and regulations or Grainger's policies. Any such violations could individually or in the aggregate materially adversely affect Grainger's financial condition or operating results.

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

Overview

General. Grainger is a broad-line distributor of maintenance, repair and operating supplies, and other related products and services used by businesses and institutions. Grainger’s operations are primarily in the United States and Canada, with a presence in Europe, Asia and Latin America. Grainger uses a multichannel business model to provide customers with a range of options for finding and purchasing products utilizing sales representatives, catalogs, direct marketing materials and eCommerce. Grainger serves more than 2 million customers worldwide through a network of highly integrated branches, distribution centers, multiple websites and export services.

Grainger’s two reportable segments are the United States and Canada. The United States segment reflects the results of Grainger’s U.S. operating segment. The Canada segment reflects the results for Acklands – Grainger Inc., Grainger’s Canadian operating segment. Other Businesses include operations in Europe, Asia, Latin America and other U.S. operations, which are not material individually.

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. The overall economy and leading economic indicators provide general insight into projecting Grainger’s growth. Grainger’s sales in the United States and Canada tend to positively correlate with Gross Domestic Product (GDP), Industrial Production, Exports and Business Investment. In the United States, sales also tend to positively correlate with Business Inventory. The table below provides these estimated indicators for 2013 and 2014:

	United States		Canada
	Estimated 2013	Forecasted 2014	Estimated 2013	Forecasted 2014
GDP	1.9%	2.7%	1.8%	2.4%
Industrial Production	2.6%	3.2%	1.3%	2.5%
Exports	2.8%	4.9%	1.2%	2.9%
Business Investment	2.9%	6.3%	1.2%	6.6%
Business Inventory	4.2%	3.0%	—	—
Source: Global Insight (February 2014)

The light and heavy manufacturing customer sectors, which comprised approximately 30% of Grainger’s total 2013 sales, have historically correlated with manufacturing employment levels and manufacturing production. Manufacturing employment levels in the United States increased approximately 0.6% from December 2012 to December 2013, while manufacturing output increased 2.6%. These increases contributed to a high single-digit percent sales increase in the light manufacturing customer sector and a mid single-digit percent sales increase in the heavy manufacturing customer sector for Grainger in 2013.

As oil production represents a large segment of the Canadian economy, fluctuations in crude oil prices can have a significant impact on the sales and business conditions in Grainger's Canadian business. According to the U.S. Energy Information Administration, crude oil prices increased from $88 to $98 per barrel, or an 11% increase from December 2012 to December 2013.

Outlook. In 2014, Grainger plans to continue to make investments in its supply chain, eCommerce, sales force and inventory management services. These investments are expected to accelerate market share growth and increase Grainger's size and scale. Grainger is also taking appropriate steps to strengthen areas of the business that are not performing to expectations.

On January 24, 2014, Grainger revised its 2014 earnings per share guidance from a range of $12.25 to $13.00 to a range of $12.10 to $12.85 and also revised its 2014 sales guidance from a range of 6 to 10 percent to a range of 5 to 9 percent. This change is primarily driven by unfavorable foreign exchange and the divestiture of the four direct marketing brands, which were sold on December 31, 2013.

13

Matters Affecting Comparability.

Grainger completed several acquisitions throughout 2013, 2012 and 2011, all of which were immaterial individually and in the aggregate. Grainger’s operating results have included the results of each business acquired since the respective acquisition dates.

2013 Compared to 2012

Grainger's net sales of $9,438 million for 2013 increased 5% when compared with net sales of $8,950 million for 2012. The 5% increase for the year consisted of the following contributors:

	Percent Increase/ (Decrease)
Volume	3
Business acquisitions	2
Price	1
Foreign exchange	(1)
Total	5%

Net sales to most customer end markets increased for 2013. The increase in net sales was led by growth in sales to heavy and light manufacturing customers, followed by diversified commercial services customers. Refer to the Segment Analysis below for further details.

Gross profit of $4,136 million for 2013 increased 6%. The gross profit margin for 2013 was 43.8%, flat versus 2012, primarily driven by price increases exceeding product cost increases, offset by lower margins from the acquired businesses and faster growth with lower margin customers.

Operating expenses of $2,840 million for 2013 increased 2% from $2,785 million for 2012. Operating expenses in 2013 included a $26 million expense related to the impairment charges for the business in Brazil and Grainger Lighting Services in the United States. Also included was $10 million of expense related to restructuring charges for improving the long-term performance of the businesses in Europe and China. Operating expenses in 2012 included a $76 million expense related to the settlement of disputes involving the GSA and USPS contracts. Also included in 2012 was $24 million of expense related to branch closure costs, restructuring charges related to improving the long-term performance of the businesses in Europe, India and China and an impairment charge for Grainger Lighting Services. Excluding these expenses from both years, operating expenses increased 4%, primarily driven by the acquisitions and an incremental $132 million in growth-related spending on new sales representatives, eCommerce and inventory management solutions, primarily in the United States.

14

Operating earnings of $1,297 million for 2013 increased 15% from $1,131 million for 2012. Excluding the expenses mentioned above for both years, operating earnings increased 8%, primarily due to higher sales and operating expenses increasing at a slower rate than sales.

Net earnings attributable to Grainger for 2013 increased by 16% to $797 million from $690 million in 2012. The increase in net earnings primarily resulted from an increase in operating earnings. Diluted earnings per share of $11.13 in 2013 were 17% higher than $9.52 for 2012, due to increased net earnings and lower average shares outstanding.

The table below reconciles reported diluted earnings per share determined in accordance with generally accepted accounting principles in the United States to adjusted diluted earnings per share, a non-GAAP measure. Management believes adjusted diluted earnings per share is an important indicator of operations because it excludes items that may not be indicative of core operating results. Because non-GAAP financial measures are not standardized, it may not be possible to compare this financial measure with other companies' non-GAAP financial measures having the same or similar names.

	Twelve Months Ended December 31,
	2013	2012	%
Diluted earnings per share reported	$11.13	$9.52	17	%

	Percent Increase
Volume	4
Business acquisitions	2
Price	1
Total	7%

Net sales to most customer end markets increased for 2013. The increase was led by high single digit growth to light manufacturing customers, followed by mid-single digit growth to heavy manufacturing, commercial services, contractors and natural resources customers. Government was up in the low single digits and net sales to resellers were down in the low single digits.

The segment gross profit margin decreased 0.3 percentage point in 2013 compared to 2012, primarily driven by lower margins from the acquired businesses and faster growth with lower margin customers, partially offset by price increases exceeding product cost increases.

Net sales to heavy manufacturing customers were down in the mid-single digits and the government end market was down in the low single digits.

The segment gross profit margin increased 0.4 percentage point in 2013 over 2012, primarily driven by price increases exceeding product cost increases and favorable freight rates, partially offset by the unfavorable effect of foreign exchange on purchases.

Operating expenses increased 2% in 2013. In local currency, operating expenses increased 5%, primarily due to higher volume-related payroll, occupancy and technology investments, partially offset by lower warehouse expenses.

Operating earnings of $129 million for 2013 were up $1 million, or 1%, versus 2012. In local currency, operating earnings increased 4%. The increase in earnings was due to sales growth and improved gross profit margins, partially offset by operating expenses increasing at a faster rate than sales.

Other Businesses

Net sales were $1,040 million for 2013, an increase of $33 million, or 3%, when compared with $1,007 million for 2012. The net sales increase was primarily due to incremental sales from Zoro Tools, Brazil and Mexico, partially offset by lower sales in India due to a change in its business model.

	Percent Increase/ (Decrease)
Volume/Price	10
Foreign exchange	(7)
Total	3%

Also included was $24 million of expense related to branch closure costs, restructuring charges related to improving the long-term performance of the businesses in Europe, India and China and an impairment charge for Grainger Lighting Services. The year 2011 included $18 million of branch closure costs. Excluding these expenses from both years, operating expenses increased 10%, primarily driven by the Fabory and AnFreixo acquisitions and incremental growth-related spending on new sales representatives, eCommerce and advertising, primarily in the United States.

Operating earnings of $1,131 million for 2012 increased 7% from $1,052 million for 2011. Excluding the expenses mentioned above for both years, operating earnings increased 15%, primarily due to higher sales and gross profit margins, and operating expenses increasing at a slightly slower rate than sales.

Segment Analysis

The following comments at the reportable segment and other business unit level include external and intersegment net sales and operating earnings. See Note 16 to the Consolidated Financial Statements.

United States

Net sales were $6,926 million for 2012, an increase of $425 million, or 7%, when compared with net sales of $6,501 million for 2011. The 7% increase for the year consisted of the following contributors:

	Percent Increase
Volume	4
Price	3
Total	7%

Sales to all customer end markets increased for 2012. The increase was led by growth in sales to heavy and light manufacturing customers, followed by diversified commercial services customers.

The segment gross profit margin increased 0.3 percentage point in 2012 over 2011, primarily driven by price increases exceeding product cost increases, partially offset by customer mix.

Operating expenses were up 8% for 2012 versus 2011. The 2012 year included a $76 million expense related to the settlement of disputes involving the GSA and USPS contracts. Also included was $10 million of expense primarily related to branch closure costs and an impairment charge for Grainger Lighting Services. The 2011 year included costs for the closure of 35 branches of $18 million. Excluding these expenses from both years, operating expenses increased 4%, primarily driven by an incremental $70 million in growth-related spending on new sales representatives, eCommerce and advertising.

For the segment, operating earnings of $1,133 million for 2012 increased 6% over $1,066 million in 2011. Excluding the expenses mentioned above in both years, operating earnings were up 12%. The improvement in operating earnings for 2012 was due to an increase in net sales and gross profit margin, and operating expenses increasing at a slower rate than sales.

18

Canada

Net sales were $1,106 million for 2012, an increase of $113 million, or 11%, when compared with $993 million for 2011. In local currency, sales increased 12% for 2012. The 11% increase for the year consisted of the following contributors:

	Percent Increase/ (Decrease)
Volume	11
Price	1
Foreign exchange	(1)
Total	11%

The increase in net sales was led by growth to oil and gas, commercial and construction customers.

The segment gross profit margin increased 0.2 percentage point in 2012 over 2011, primarily driven by price increases exceeding product cost increases, partially offset by unfavorable customer and product mix.

Operating expenses increased 9% in 2012. In local currency, operating expenses increased 10% primarily due to higher volume-related payroll and travel costs, and higher advertising and depreciation expense, partially offset by lower occupancy costs.

Operating earnings of $127 million for 2012 were up $20 million, or 18%, versus 2011. In local currency, operating earnings increased 19%. The increase in earnings was due to strong sales growth, an improved gross profit margin and expense leverage.

Other Businesses

Net sales for other businesses, which include operations in Europe, Asia, Latin America and other U.S. operations were up 55% for 2012. The sales increase was due primarily to a full year of sales from Fabory, acquired in August 2011, and incremental sales from AnFreixo, acquired in April 2012, as well as strong growth from the businesses in Japan and Mexico.

Operating earnings for other businesses were $20 million for 2012 compared to $31 million for 2011. The decrease was primarily due to restructuring charges related to improving the long-term performance of the businesses in Europe, India and China. Excluding these charges, operating earnings were up $3 million, primarily driven by improved performance in Japan and Mexico, partially offset by losses from the acquired businesses in Europe and Brazil, along with losses in some start-up businesses in developing markets.

Other Income and Expense

Other income and expense was $13 million of expense in 2012 compared with $1 million of expense in 2011. The following table summarizes the components of other income and expense (in thousands of dollars):

	For the Years Ended December 31,
	2012			2011
Interest income (expense) - net	$	(13,418	)	$	(7,023	)
Equity in net income of unconsolidated entity	—			314
Gain on sale of investment in unconsolidated entity	—			7,639
Other non-operating income	1,866			709
Other non-operating expense	(1,784		)	(2,541		)
Total	$	(13,336	)	$	(902	)

Net interest expense increased in 2012 due to higher average outstanding debt, higher average interest rates and interest expense related to capital leases for the acquired business in Europe.

In 2011, Grainger divested its 49% ownership in the MRO Korea Co., Ltd. joint venture, resulting in a gain of approximately $8 million.

19

Income Taxes

Income taxes of $419 million in 2012 increased 9% as compared with $385 million in 2011. Grainger's effective tax rates were 37.5% and 36.6% in 2012 and 2011, respectively. The 2011 rate benefited from a tax law change in Japan and the settlement of various tax reviews. Excluding these benefits in 2011, the effective tax rate was 38.1%. The effective tax rate in 2012 benefited primarily from a lower blended state tax rate.

Financial Condition

Grainger expects its strong working capital position, cash flows from operations and borrowing capacity to continue, allowing it to fund its operations, including growth initiatives, capital expenditures, acquisitions and repurchase of shares, as well as to pay cash dividends.

Cash Flow

Fiscal year 2013 compared with fiscal year 2012

Cash from operating activities continues to serve as Grainger's primary source of liquidity. Net cash flows from operations in 2013 were $986 million and increased $170 million from $816 million in 2012. The primary driver of the improvement was an increase in net earnings of $109 million. In addition, changes in operating assets and liabilities resulted in a net use of cash of $58 million for 2013 compared to $129 million for 2012. The lower use of cash for operating assets and liabilities was driven primarily by higher trade accounts payable due to higher inventory purchases at year-end in 2013 compared to 2012, partially offset by higher accounts receivable from increased sales.

Net cash used in investing activities was $399 million and $306 million in 2013 and 2012, respectively. The higher use of cash in 2013 compared to 2012 was primarily driven by the increased cash paid for acquisitions and cash expended for property, buildings, equipment and software.

Net cash used in financing activities of $591 million in 2013 increased $197 million from $394 million in 2012. The increase was primarily due to higher treasury share repurchases. Cash paid for treasury share purchases was $438 million in 2013 versus $341 million in 2012, an increase of $97 million. The prior year also included $300 million in proceeds from the issuance of long-term debt.

Fiscal year 2012 compared with fiscal year 2011

Cash from operating activities served as Grainger's primary source of liquidity. Net cash flows from operations in 2012 were $816 million and increased $70 million from $746 million in 2011. The primary driver of the improvement was an increase in net earnings of $32 million as well as an increase of $34 million in net non-cash expenses.

Net cash used in investing activities of $306 million in 2012 was driven by net cash expended for property, buildings, equipment and software of $241 million and net cash paid for business acquisitions of $65 million. Additional information regarding capital spending is detailed in the Capital Expenditures section below. Net cash used in investing activities was $229 million less than in 2011 due primarily to a decrease in net cash paid for business acquisitions of $294 million versus 2011.

Net cash used in financing activities of $394 million in 2012 increased $217 million from $177 million in 2011. The increase was primarily due to higher treasury shares repurchases and higher dividends paid in 2012 versus 2011. Cash paid for treasury share purchases was $341 million in 2012 versus $151 million in 2011, an increase of $190 million. Cash dividends paid were $220 million in 2012, an increase of $39 million versus 2011.

20

Working Capital

Internally generated funds are the primary source of working capital and funds used in business expansion, supplemented by debt. In addition, funds are expended to support growth initiatives, as well as for business and systems development and other infrastructure improvements.

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 $1,621 million at December 31, 2013, compared with $1,604 million at December 31, 2012. At these dates, the ratio of current assets to current liabilities was 2.5 and 2.6, respectively.

Capital Expenditures

In each of the past three years, a portion of operating cash has been used for additions to property, buildings, equipment and capitalized software as summarized in the following table (in thousands of dollars):

	For the Years Ended December 31,
	2013		2012		2011
Land, buildings, structures and improvements	$	60,419	$	57,929	$	51,249
Furniture, fixtures, machinery and equipment	152,328		145,483		118,228
Subtotal	212,747		203,412		169,477
Capitalized software	59,398		46,448		27,465
Total	$	272,145	$	249,860	$	196,942

In 2013 and 2012, Grainger made significant capital investments to build new distribution centers in the United States and Canada. In the United States, Grainger opened a new 1 million square-foot and highly automated Chicago-area distribution center in 2013. In Canada, Grainger began construction of a 500,000 square-foot distribution center in the Toronto area. Grainger also invested in vending machines for KeepStock, as this program continues to grow. Other significant investments in 2013 and 2012 included investing in a new eCommerce platform, sustaining capital investments for Grainger's branches and distribution centers and other technology infrastructure.

In 2011, significant expenditures were made to build new distribution centers in the United States and for distribution center expansion in Canada. Also, a large investment was made to update and improve the eCommerce platform in the United States business. Finally, Grainger continued to invest in new and existing international businesses, as well as for normal recurring replacement of equipment.

In 2014, capital expenditures are expected to range from $375 million to $425 million. Projected spending includes continued investments in the supply chain, technology infrastructure, eCommerce and in support of sales initiatives. Grainger expects to fund 2014 capital spending from operating cash.

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. Refer to Note 6 and Note 7 to the Consolidated Financial Statements included in Item 8. Total debt as a percent of total capitalization was 14.0% and 15.3% as of December 31, 2013 and 2012, respectively. The reduction in total debt as a percent of total capitalization was primarily due to increased retained earnings associated with higher earnings in 2013. Grainger believes any circumstances that would trigger early payment or acceleration with respect to any outstanding debt obligations would not have a material impact on its results of operations or financial position.

21

Commitments and Other Contractual Obligations

At December 31, 2013, Grainger's contractual obligations, including estimated payments due by period, are as follows (in thousands of dollars):

	Payments Due by Period
	Total Amounts Committed		Less than 1 Year		1 - 3 Years		4 - 5 Years		More than 5 Years
Debt obligations	$	542,799	$	97,286	$	429,010	$	2,498	$	14,005
Interest on debt	28,367		9,992		13,574		4,771		30
Operating lease obligations	230,644		67,993		97,929		44,785		19,937
Purchase obligations:
Uncompleted additions to property, buildings and equipment	65,536		65,536		—		—		—
Commitments to purchase inventory	402,935		402,935		—		—		—
Other purchase obligations	261,773		176,651		63,233		21,833		56
Other liabilities	303,324		185,272		23,862		24,554		69,636
Total	$	1,835,378	$	1,005,665	$	627,608	$	98,441	$	103,664

Purchase obligations for inventory 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 employee benefits plans as determined by actuarial projections, and other employee benefit plans. Other employment-related benefits costs of $50 million have not been included in this table as the timing of benefit payments is not predictable. See Note 9 to the Consolidated Financial Statements.

See also Note 7 and Note 10 to the Consolidated Financial Statements for further detail related to the interest on long-term debt and operating lease obligations, respectively.

Grainger has recorded a noncurrent liability of approximately $44 million for tax uncertainties and interest at December 31, 2013. This amount is excluded from the table above, as Grainger cannot make reliable estimates of these cash flows by period. See Note 14 to the Consolidated Financial Statements.

Off-Balance Sheet Arrangements

Grainger does not have any material exposures to off-balance sheet arrangements. Grainger does not have any variable interest entities or activities that include non-exchange-traded contracts accounted for at fair value.

22

Critical Accounting Estimates

The preparation of financial statements, in conformity with accounting principles generally accepted in the United States of America, requires management to make judgments, estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses in the financial statements. Management bases its estimates on historical experience and other assumptions, which it believes are reasonable. If actual amounts are ultimately different from these estimates, the revisions are included in Grainger's results of operations for the period in which the actual amounts become known.

Accounting policies are considered critical when they require management to make assumptions about matters that are highly uncertain at the time the estimates are made and when there are different estimates that management reasonably could have made, which would have a material impact on the presentation of Grainger's financial condition, changes in financial condition or results of operations.

Note 1 to the Consolidated Financial Statements describes the significant accounting policies used in the preparation of the Consolidated Financial Statements. The most significant areas involving management judgments and estimates follow. Actual results in these areas could differ materially from management's estimates under different assumptions or conditions.

Allowance for Doubtful Accounts. Grainger considers several factors to estimate the allowance for uncollectible accounts receivable including the age of the receivables, the percent past due and the historical ratio of actual write-offs to the age of the receivables. The analyses performed also take into consideration economic conditions that may have an impact on a specific industry, group of customers or a specific customer. Based on analysis of actual historical write-offs of uncollectible accounts receivable, Grainger's estimates and assumptions have been materially accurate in regards to the valuation of its allowance for doubtful accounts. However, write-offs could be materially different than the reserves established if business or economic conditions change or actual results deviate from historical trends, and Grainger's estimates and assumptions may be revised as appropriate to reflect these changes. For fiscal years 2013, 2012 and 2011, actual results did not vary materially from estimated amounts.

Inventory Reserves.  Grainger establishes inventory reserves for 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 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 1.4 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 the methodology provides for a materially accurate level of reserves at any reporting date.  Actual results could differ materially from projections and require changes to reserves which 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 2013, 2012 and 2011, actual results did not vary materially from estimated amounts.

Goodwill and Indefinite Lived Intangible Assets. Business acquisitions result in the recording of goodwill and identified intangible assets which affect the amount of amortization expense and possible impairment write-downs that may occur in future periods. Grainger annually reviews goodwill and intangible assets with indefinite lives for impairment in the fourth quarter and when events or changes in circumstances indicate the carrying value of these assets might exceed their current fair values. Grainger tests for goodwill impairment at the reporting unit level and performs a qualitative assessment of factors such as a reporting unit's current performance and overall economic factors to determine if it is more likely than not that the goodwill might be impaired and whether it is necessary to perform the two-step quantitative goodwill impairment test. In the two-step test, Grainger compares the carrying value of assets of the reporting unit to its calculated fair value. If the carrying value of assets of the reporting unit exceeds its calculated fair value, the second step is performed, where the implied fair value of goodwill is compared to the carrying value of assets, to determine the amount of impairment.

23

The fair value of reporting units is calculated primarily using the discounted cash flow (DCF) method and incorporating value indicators from a market approach to evaluate the reasonableness of the resulting fair values. The DCF method incorporates various assumptions including the amount and timing of future expected cash flows, including revenues, gross margins, operating expenses, capital expenditures and working capital based on operational budgets, long range strategic plans and other estimates. The terminal value growth rate is used to calculate the value of cash flows beyond the last projected period and reflects management’s best estimates for perpetual growth for the reporting units. Estimates of market-participant risk-adjusted weighted average cost of capital (WACC) are used as a basis for determining the discount rates to apply to the reporting units’ future expected cash flows and terminal value.

Grainger completed the annual impairment testing using the qualitative approach for seven reporting units and the two-step quantitative test for four of these reporting units during the fourth quarter. For two of these reporting units, Grainger Lighting Services (GLS) and Grainger Brazil (GB), the two-step quantitative test indicated that the carrying value of assets exceeded the calculated fair value and step two impairment calculations were required. As part of the review of the strategic plans for GLS during the fourth quarter, Grainger evaluated the impact of planned changes to the business model and level of investment in the business. Grainger’s estimates of future projected sales growth, operating earnings, and cash flows were revised to reflect lower estimates for new customers and projects.  As a result of the lower projections, Grainger recognized impairment charges of $13 million on the GLS reporting unit.

During the fourth quarter, management provided strategic plans which included changes to the business model and level of investment required for GB based on insights gained from owning the business since the acquisition in the second quarter of 2012. Grainger’s assumptions were revised to reflect changes related to realization of expected deal synergies and anticipated short-term and long-term operating results of GB that were different from pre-acquisition projections. As a result of the lower performance expectations, Grainger’s estimates for future projected sales growth, operating earnings, and cash flows were revised accordingly. These lowered expectations, as well as an increase in relevant risk factors that increased the discount rate used in the calculations, resulted in the calculated fair value of GB being lower than the carrying value of assets in the step one analysis.  As a result of the completion of step two, Grainger recognized a goodwill impairment charge of $11 million.

For the two other reporting units, the fair values calculated in the step one analysis exceeded the carrying value of assets and therefore the step two calculation was not required. Fabory, with $134 million of goodwill, had a calculated fair value which exceeded the carrying value of assets by 17%. The risk of potential failure of step one of the impairment test for Fabory in future reporting periods is highly dependent upon key assumptions including the amount and timing of future expected cash flows, sales growth rates, gross margins, capital expenditures, discount rates and estimates of market-participant risk-adjusted WACC. These assumptions require considerable management judgment and are subject to uncertainty. Changes in assumptions regarding the future performance and a continued unfavorable economic environment in Europe may also have a significant impact on cash flows in the future. Given the sensitivity of the calculated fair value to changes in these key assumptions, Grainger may be required to recognize an impairment for Fabory’s goodwill in the future due to changes in market conditions or other factors related to these key assumptions.

Grainger Colombia, with $14 million of goodwill, had a calculated fair value which exceeded the carrying value of assets by 26% as of the test date.

24

Stock Incentive Plans. Grainger maintains stock incentive plans under which a variety of incentive grants may be awarded to employees and directors. Grainger uses a binomial lattice option pricing model to estimate the fair value of stock option grants. The model requires projections of the risk-free interest rate, expected life, volatility, dividend yield and forfeiture rate of the stock option grants. The fair value of options granted used the following assumptions:

	For the Years Ended December 31,
	2013	2012	2011
Risk-free interest rate	0.9%	1.1%	2.6%
Expected life	6 years	6 years	6 years
Expected volatility	25.5%	25.9%	24.6%
Expected dividend yield	1.5%	1.6%	1.8%

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 holders' exercise and termination behavior. Expected volatility is based upon implied and historical volatility of the closing price of Grainger's stock over a period equal to the expected life of each option grant. Historical information is also the primary basis for selection of the expected dividend yield assumptions. Because stock option compensation expense is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures, using historical forfeiture experience. The amount of stock option compensation expense is significantly affected by the valuation model and these assumptions. If a different valuation model or different assumptions were used, the stock option compensation expense could be significantly different from what is recorded in the current period.

Compensation expense for other stock-based awards is based upon the closing market price on the last trading date preceding the date of the grant. Because the expense for other stock-based awards should reflect the awards ultimately expected to vest, it has been reduced for estimated forfeitures, using historical forfeiture experience.

For additional information concerning stock incentive plans, see Note 11 to the Consolidated Financial Statements.

Postretirement Healthcare Benefits. Postretirement healthcare obligation and net periodic cost are dependent on assumptions and estimates used in calculating such amounts. The assumptions used include, among others, discount rates, assumed rates of return on plan assets and healthcare cost trend rates, and certain employee-related factors, such as turnover, retirement age and mortality rates. Changes in these and other assumptions (caused by conditions in equity markets or plan experience, for example) could have a material effect on Grainger's postretirement benefit obligation and expense, and could affect its results of operations and financial condition. These changes in assumptions may also affect voluntary decisions to make additional contributions to the trust established for funding the postretirement benefit obligation.

The discount rate assumptions used by management reflect the rates available on high-quality fixed income debt instruments as of December 31, the measurement date, of each year. A higher discount rate reduces the present value of benefit obligations and net periodic benefit costs.As of December 31, 2013, Grainger increased the discount rate used in the calculation of the postretirement plan obligation from 4.0% to 4.9% to reflect the increase in market interest rates. Grainger estimates that this increase could increase 2014 pretax earnings by approximately $4 million. However, other changes in assumptions may increase, decrease or eliminate this effect.

Grainger considers the long-term historical actual return on plan assets and the historical performance of the Standard & Poor's 500 Index and the Total International Composite Index in developing its expected long-term return on plan assets. In 2013, Grainger decreased the expected long-term rate of return on plan assets from 6.0% (net of tax) to 5.7% (net of tax) based on the historical average of long-term rates of return. Grainger estimates this change could reduce 2014 pretax earnings by approximately $0.4 million.

The Company’s healthcare trend rate is selected based on historical experience and expected experience. Grainger changed the duration of the healthcare trend rate from an assumed rate of increase of 7.5% declining 50 basis points a year until reaching the ultimate trend rate of 5% to an assumed rate of increase of 7.5% declining 25 basis points a year until reaching the ultimate trend rate of 4.5%. Grainger estimates this change could reduce 2014 pretax earnings by approximately $1 million.

25

A 1 percentage point change in assumed healthcare cost trend rates would have had the following effects on December 31, 2013 results (in thousands of dollars):

	1 Percentage Point
	Increase		(Decrease)
Effect on total of service and interest cost	$	2,205	$	(1,777	)
Effect on postretirement benefit obligation	29,776		(24,196		)

Grainger changed the mortality improvement scale used to project mortality rates into the future from Mortality Improvement Scale AA to Mortality Improvement Scale BB at December 31, 2013. Grainger estimates this change could reduce 2014 pretax earnings by approximately $2 million.

Grainger may terminate or modify the postretirement plan at any time, subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA) and the Internal Revenue Code, as amended. In the event the postretirement plan is terminated, all assets of the Group Benefit Trust inure to the benefit of the participants. The foregoing assumptions are based on the presumption that the postretirement plan will continue. Were the postretirement plan to terminate, different actuarial assumptions and other factors might be applicable.

Grainger has used its best judgment in making assumptions and estimates and believes such assumptions and estimates used are appropriate. Changes to the assumptions may be required in future years as a result of actual experience or new trends or plan changes and, therefore, may affect Grainger's retirement plan obligations and future expense. For additional information concerning postretirement healthcare benefits, see Note 9 to the Consolidated Financial Statements.

Insurance Reserves.  Grainger retains a significant portion of the risk of certain losses related to workers' compensation, general liability and property losses through the utilization of high deductibles and self-insured retentions.  There are also certain other risk areas for which Grainger does not maintain insurance.

Grainger is responsible for establishing accounting policies on insurance reserves.  Although it relies on outside parties to project future claims costs, it retains control over actuarial assumptions, including loss development factors and claim payment patterns.  Grainger performs ongoing reviews of its insured and uninsured risks, which it uses to establish the appropriate reserve levels.  In calculating the liability, historical trends, claims experience and loss development patterns are analyzed and appropriate loss development factors are applied to the incurred costs associated with the claims made.

The use of assumptions in the analysis leads to fluctuations in required reserves over time.  Any change in the required reserve balance is reflected in the current period's results of operations.  Grainger believes its estimates are reasonable based on the information currently available and the methodology used to estimate these reserves has been consistently applied.  There were no material adjustments based on Grainger's historical experience in 2013, 2012 and 2011.  If actual trends, including the nature, severity or frequency of claims differ from Grainger's estimates, or if business or economic conditions change, Grainger's estimates and assumptions may be revised as appropriate and the results of operations could be materially impacted.

Income Taxes. Grainger recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities, using enacted tax rates in effect for the year in which the differences are expected to reverse. 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. 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.

26

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, wage and hour laws, intellectual property, employment practices, regulatory compliance or other matters and actions brought by employees, consumers, competitors, suppliers or governmental entities. 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 exposure, as appropriate, for claims against Grainger when losses become probable and reasonably estimable. 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 material. 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.

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 Consolidated Financial Statements.

Inflation

Inflation during the last three years has not had a significant effect on operations. 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 has been able to successfully pass on cost increases to its customers minimizing the effect of inflation on results of operations.

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.

27

Forward-Looking Statements

This Form 10-K contains statements that are not historical in nature but concern future results and business plans, strategies and objectives and other matters that may be deemed to be “forward-looking statements” under the federal securities laws. Grainger has generally identified such forward-looking statements by using words such as “ anticipated, assumed, assumes, assumptions, believe, believes, can, continue, continued, continues, could, estimate, estimated, estimates, expect, expectation, expectations, expected, expects, forecasted, forecasts, guidance, if, intended, intends, maintain, maintains, may, might, no assurance, plans, predict, predictable, presumption, project, projected, projecting, projections, potential, potentially, reasonably likely, risk, scheduled, should, tend, unanticipated, will, and would” or similar expressions.

Grainger cannot guarantee that any forward-looking statement will be realized, although Grainger does believe that its assumptions underlying its forward-looking statements are reasonable. Achievement of future results is subject to risks and uncertainties that could cause Grainger's results to differ materially from those which are presented.

Factors that could cause actual results to differ materially from those presented or implied in a forward-looking statement include, without limitation: higher product costs or other expenses; a major loss of customers; loss or disruption of source of supply; increased competitive pricing pressures; failure to develop or implement new technologies or business strategies; the outcome of pending and future litigation or governmental or regulatory proceedings; investigations, inquiries, audits and changes in laws and regulations; disruption of information technology or data security systems; general industry or market conditions; general global economic conditions; currency exchange rate fluctuations; market volatility; commodity price volatility; labor shortages; litigation involving appropriate payment for wages; facilities disruptions or shutdowns; higher fuel costs or disruptions in transportation services; natural and other catastrophes; unanticipated weather conditions; and the factors identified in Item 1A, Risk Factors.

Caution should be taken not to place undue reliance on Grainger's forward-looking statements and Grainger undertakes no obligation to publicly update the forward-looking statements, whether as a result of new information, future events or otherwise.

28

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. See Note 8 and Note 13 to the Consolidated Financial Statements for additional information on Grainger's derivative activities.

Foreign Currency Exchange Rates

Grainger's international subsidiaries generate revenue and expenses in their local currencies. Grainger's consolidated earnings are subject to foreign currency translation exposure upon conversion of a foreign entity's statement of earnings from the functional currency to the reporting currency, which is the U.S. dollar. For 2013, a uniform 10% strengthening of the U.S. dollar relative to foreign currencies that affect Grainger's international subsidiaries would have resulted in a $6 million decrease in net earnings. Comparatively, in 2012 a uniform 10% strengthening of the U.S. dollar relative to foreign currencies that affect Grainger's international subsidiaries would have resulted in a $7 million decrease in net earnings. A uniform 10% weakening of the U.S. dollar would have resulted in a $7 million increase in net earnings for 2013, as compared with an increase in net earnings of $8 million for 2012. 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.

Interest Rates

Grainger is subject to interest rate risk related to its variable rate debt portfolio. Grainger may enter into interest rate swap agreements to manage those risks. Based on Grainger's variable rate debt and derivative instruments outstanding, a 1 percentage point increase in interest rates paid by Grainger would have resulted in a decrease to net earnings of approximately $3 million for 2013 and $2 million for 2012. A 1 percentage point decrease in interest rates would have resulted in an increase to net earnings of approximately $3 million for 2013 and $2 million for 2012. This sensitivity analysis of the effects of changes in interest rates on long-term debt does not factor in future potential changes in long-term debt levels.

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, 2013, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992 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, 2013.

Ernst & Young LLP, an independent registered public accounting firm, has audited Grainger's internal control over financial reporting as of December 31, 2013, as stated in their report, which is included herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders

W.W. Grainger, Inc.

We have audited W.W. Grainger, Inc. and subsidiaries' (the “Company”) internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992 framework) (the COSO criteria). W.W. Grainger, Inc.'s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). 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.

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.

In our opinion, W.W. Grainger, Inc. and subsidiaries maintained, in all material respects, effective internal control over financial reporting as of December 31, 2013, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of W.W. Grainger, Inc. and subsidiaries as of December 31, 2013 and 2012, 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, 2013 of W.W. Grainger, Inc. and subsidiaries and our report dated February 27, 2014 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders

W.W. Grainger, Inc.

We have audited the accompanying consolidated balance sheets of W.W. Grainger, Inc. and subsidiaries as of December 31, 2013 and 2012, 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, 2013. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of W.W. Grainger, Inc. and subsidiaries at December 31, 2013 and 2012, and the consolidated results of their operations and their cash flows for each of the three years in the period ended December 31, 2013, 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), W.W. Grainger Inc. and subsidiaries' internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992 framework) and our report dated February 27, 2014 expressed an unqualified opinion thereon.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

INDUSTRY INFORMATION

W.W. Grainger, Inc. is a broad-line distributor of maintenance, repair and operating supplies, and other related products and services used by businesses and institutions. 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. All significant intercompany transactions are eliminated from the consolidated financial statements.

EQUITY METHOD OF ACCOUNTING FOR INVESTMENTS

For investments in which the Company owns or controls from 20% to 50% of the voting shares, the equity method of accounting is used. The Company also accounts for investments below 20% using the equity method when significant influence can be exercised over the operating and financial policies of the investee company.

In October 2011, the Company divested its 49% stake in a joint venture, MRO Korea Co., Ltd., for $12 million, resulting in a pretax gain of $8 million ($5 million after-tax) net of the cumulative foreign currency losses reclassified from Accumulated other comprehensive earnings. The Company previously accounted for this investment under the equity method.

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 financial statements of the Company's foreign subsidiaries are measured using the local currency as the functional currency. Net exchange gains or losses resulting from the translation of financial statements of foreign operations and related long-term debt and derivative instruments are recorded as a separate component of other comprehensive earnings. See Note 13 to the Consolidated Financial Statements.

RECLASSIFICATIONS

Certain amounts in the 2012 and 2011 financial statements, as previously reported, have been reclassified to conform to the 2013 presentation. These reclassifications did not have a material impact on the presentation of the consolidated financial statements.

REVENUE RECOGNITION

Revenues recognized include product sales, billings for freight and handling charges and fees earned for services provided. The Company recognizes product sales and billings for freight and handling charges primarily on the date products are shipped to, or picked up by, the customer. In cases where the product is shipped directly to the customer, the company recognizes revenue at the time of shipment on a gross basis. The Company's standard shipping terms are FOB shipping point. On occasion, the Company will negotiate FOB destination terms. These sales are recognized upon delivery to the customer. eCommerce revenues, which accounted for 33% of total 2013 revenues, are recognized on the same terms as revenues through other channels. Fee revenues, which accounted for less than 1% of total 2013 revenues, are recognized after services are completed. Taxes collected from customers and remitted to governmental authorities are presented on a net basis and are not included in revenue.

COST OF MERCHANDISE SOLD

Cost of merchandise sold includes product and product-related costs, vendor consideration, freight-out and handling costs. The Company defines handling costs as those costs incurred to fulfill a shipped sales order.

46

VENDOR CONSIDERATION

The Company receives rebates and allowances from its vendors to promote their products. The Company utilizes numerous advertising programs to promote its vendors' products, including catalogs and other printed media, Internet, radio and other marketing programs. Most of these programs relate to multiple vendors, which makes supporting the specific, identifiable and incremental criteria difficult, and would require numerous assumptions and judgments. Based on the inexact nature of trying to track reimbursements to the advertising expenditure for each vendor, the Company treats most vendor advertising allowances as a reduction to Cost of merchandise sold rather than a reduction of operating (advertising) expenses. 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 Cost of merchandise sold based on sales. Vendor rebates that are earned based on products sold are credited directly to Cost of merchandise sold.

ADVERTISING

Advertising costs are expensed in the year the related advertisement is first presented. Advertising expense was $178 million, $173 million and $145 million for 2013, 2012 and 2011, respectively. Most vendor-provided allowances are classified as an offset to Cost of merchandise sold. For additional information see VENDOR CONSIDERATION above.

Catalog expense is amortized equally over the life of the catalog, beginning in the month of its distribution. Advertising costs for catalogs that have not been distributed by year-end are capitalized as Prepaid expenses. Amounts included in Prepaid expenses at December 31, 2013 and 2012, were $36 million and $46 million, respectively.

WAREHOUSING, MARKETING AND ADMINISTRATIVE EXPENSES

Included in this category are purchasing, 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. See Note 11 to the Consolidated 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. See Note 14 to the Consolidated Financial Statements.

OTHER COMPREHENSIVE EARNINGS (LOSSES)

The Company's Other comprehensive earnings (losses) include foreign currency translation adjustments, changes in fair value of derivatives designated as hedges and unrecognized gains (losses) on postretirement and other employment-related benefit plans. See Note 13 to the Consolidated 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.

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 all regions of the United States, Canada, Europe, Asia and Latin America. Consequently, no significant concentration of credit risk is considered to exist.

ALLOWANCE FOR DOUBTFUL ACCOUNTS

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.

47

INVENTORIES

Inventories are valued at the lower of cost or market. Cost is determined primarily by the last-in, first-out (LIFO) method, which accounts for approximately 59% of total inventory. For the remaining inventory, cost is determined by the first-in, first-out (FIFO) method.

PROPERTY, BUILDINGS AND EQUIPMENT

Property, buildings and equipment are valued at cost. For financial statement purposes, depreciation and amortization are provided 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	10 to 30 years
Furniture, fixtures, machinery and equipment	3 to 10 years

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 $1 million in each of years 2013, 2012 and 2011.

LONG-LIVED ASSETS

The carrying value of long-lived assets 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 carrying amount exceeds the fair value.

The Company recognized impairment charges of $0.4 million, $2 million and $8 million in 2013, 2012 and 2011, respectively, included in Warehousing, marketing and administrative expenses, to reduce the carrying value of certain long-lived assets to their estimated fair value pursuant to impairment indicators for property currently held for sale, lease terminations, idle assets and branch closures.

CAPITALIZED SOFTWARE

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 and five years. Amortization begins when the software is available for its intended use. Amortization expense was $23 million, $16 million and $19 million for the years ended December 31, 2013, 2012 and 2011, respectively. Capitalized software was $107 million and $72 million at December 31, 2013 and 2012, respectively and are included in Other assets and intangibles - net on the Consolidated Balance Sheets.

GOODWILL AND OTHER INTANGIBLES

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 implied fair value of goodwill is less than its carrying value.

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 unless the estimated useful life is determined to be indefinite. Amortizable intangible assets are being amortized primarily over useful lives of three to 22 years. The straight-line method of amortization is used as it has been determined to approximate customer attrition patterns and the use pattern of the assets. Impairment losses are recognized if the carrying amount of an intangible, subject to amortization, is not recoverable from expected future cash flows and its carrying amount exceeds its fair value.

48

The Company also maintains intangible assets with indefinite lives, which are not amortized. These intangibles are tested for impairment on an annual basis and more often if circumstances require. Impairment losses are recognized whenever the implied fair value of these assets is less than their carrying value. See Note 2 and Note 3 to the Consolidated Financial Statements.

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. The carrying value of long-term debt also approximates fair value due to the variable interest rates. The fair value of the Company's qualifying derivative instruments is recorded in the Consolidated Balance Sheets and is discussed in more detail in Note 8 to the Consolidated Financial Statements.

DERIVATIVE INSTRUMENTS AND HEDGING

The Company uses derivative financial instruments to manage exposures to fluctuations in interest rates and foreign currency exchange rates. The Company does not enter into derivative financial instruments for trading or speculative purposes. All derivative instruments are recognized as either assets or liabilities in the balance sheet at their fair value. Changes in the fair value of derivatives are recognized in net earnings or other comprehensive earnings (losses) depending on whether the derivative is designated as part of a qualifying hedging relationship. The ineffective portion of a qualifying hedging derivative and derivatives not designated as a hedge are recognized immediately in earnings. Instruments that do not qualify for hedge accounting are marked to market with the change recognized in current period earnings. See Note 8 and Note 13 to the Consolidated Financial Statements for additional information on the Company's derivative activities.

INSURANCE RESERVES

The Company purchases insurance for catastrophic exposures and those risks required to be insured by law. It also retains a significant portion of the risk of certain losses related to workers' compensation, general liability and property losses through the utilization of high deductibles and self-insured retentions. Reserves for these potential losses are based on an external analysis of the Company's historical claims results and other actuarial assumptions.

WARRANTY RESERVES

The Company generally warrants the products it sells against defects for one year. For a significant portion of warranty claims, the manufacturer of the product is responsible for expenses. For warranty expenses not covered by the manufacturer, the Company provides a reserve for future costs based primarily on historical experience. Warranty reserves were $4 million at December 31, 2013 and 2012.

NEW ACCOUNTING STANDARDS

In February 2013, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. Under ASU 2013-02, an entity is required to provide information about the amounts reclassified out of accumulated other comprehensive income (AOCI) by component. In addition, an entity is required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of AOCI by the respective line items of net income, but only if the amount reclassified is required to be reclassified in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide details about those amounts. ASU 2013-02 does not change the current requirements for reporting net income or other comprehensive income in the financial statements. ASU 2013-02 is effective for interim and annual periods beginning after December 15, 2012 and early adoption is permitted. The Company adopted ASU 2013-02 in the first quarter of 2013. The adoption of ASU 2013-02 did not have a material impact on the consolidated financial statements.

In July 2013, the Financial Accounting Standards Board issued ASU 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. The guidance requires the presentation of certain unrecognized tax benefits as reductions to deferred tax assets rather than as liabilities in the condensed consolidated balance sheets when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The amendments will be effective for interim and annual periods beginning after December 15, 2013. Early adoption and retrospective application are permitted. The Company does not expect the adoption of ASU 2013-11 to have a material impact on the Company’s consolidated financial statements.

NOTE 2 - BUSINESS ACQUISITIONS

On December 3, 2013, the Company acquired Safety Solutions, Inc. With 2012 sales of $63 million, Safety Solutions is a distributor of safety footwear, supplies and services with a strong focus on the manufacturing sector. The Company paid $30 million for the Safety Solutions acquisition, less cash acquired. Goodwill and intangibles recorded totaled approximately $21 million.The purchase price allocation has not been finalized and is subject to change as the Company obtains additional information during the measurement period related to the valuation of the acquired assets and liabilities.

On August 23, 2013, the Company acquired E&R Industrial Sales, Inc. With 2012 sales of approximately $180 million, E&R Industrial is a distributor of metalworking, production supplies and MRO materials to manufacturers and industrial customers across the Midwest and Eastern United States. The Company paid $116 million for the E&R Industrial acquisition, less cash acquired. Goodwill and intangibles recorded totaled approximately $80 million. The purchase price allocation has not been finalized and is subject to change as the Company obtains additional information during the measurement period related to the valuation of the acquired assets and liabilities.

On April 18, 2013, the Company acquired the remaining noncontrolling interest in Grainger Colombia for $10 million.

During 2012, the Company acquired Techni-Tool, Inc., for $43 million, less cash acquired. Goodwill recorded totaled $10 million. Purchased identified intangible assets totaled $20 million. Acquired intangibles primarily consist of customer relationships, trademarks and trade names. The customer relationships are amortized on a straight-line basis over 13 years and the trade names are amortized on a straight-line basis over 3 years. The acquired trademark is classified as an indefinite-lived intangible asset.

During 2012, the Company acquired AnFreixo S.A., for $25 million, less cash acquired. Goodwill recorded totaled $11 million. Purchased identified intangible assets totaled $9 million. Acquired intangibles primarily consist of customer relationships and a supply contract. The 2 customer relationship intangible assets are amortized on a straight-line basis over 11 years and 15 years, respectively. The supply contract intangible is amortized on a straight-line basis over 4 years.

During 2011, the Company acquired Fabory for $358 million, less cash acquired. Goodwill recorded totaled $140 million. Purchased identified intangible assets totaled $131 million. Acquired intangibles primarily consist of customer relationships and trade names. The customer relationships are amortized on a straight-line basis over 22 years. The indefinite-lived intangible is related to the Fabory trade name and trademarks.

The results of these acquisitions are included in the Company's consolidated results from the respective dates of acquisition. Due to the immaterial nature of these transactions, both individually and in the aggregate, disclosures of amounts assigned to the acquired assets and assumed liabilities and pro forma results of operations were not considered necessary.

NOTE 3 - GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill is recognized as the excess cost of an acquired entity over the 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 implied fair value of goodwill is less than its carrying value.

The changes in the carrying amount of goodwill by segment are as follows (in thousands of dollars):

	United States			Canada			Other Businesses			Total
Balance at January 1, 2012	$	151,231		$	150,645		$	207,307		$	509,183

Balance at December 31, 2013	$	180,498		$	144,588		$	200,381		$	525,467

Business acquisitions result in the recording of goodwill and identified intangible assets which affect the amount of amortization expense and possible impairment write-downs that may occur in future periods. Grainger annually reviews goodwill and intangible assets with indefinite lives for impairment in the fourth quarter and when events or changes in circumstances indicate the carrying value of these assets might exceed their current fair values. Grainger tests for goodwill impairment at the reporting unit level and performs a qualitative assessment of factors such as a reporting unit's current performance and overall economic factors to determine if it is more likely than not that the goodwill might be impaired and whether it is necessary to perform the two-step quantitative goodwill impairment test. In the two-step test, Grainger compares the carrying value of assets of the reporting unit to its calculated fair value. If the carrying value of assets of the reporting unit exceeds its calculated fair value, the second step is performed, where the implied fair value of goodwill is compared to the carrying value of assets, to determine the amount of impairment.

The fair value of reporting units is calculated using primarily the discounted cash flow (DCF) method and incorporating value indicators from a market approach to evaluate the reasonableness of the resulting fair values. The DCF method incorporates various assumptions including the amount and timing of future expected cash flows, including revenues, gross margins, operating expenses, capital expenditures and working capital based on operational budgets, long range strategic plans and other estimates. The terminal value growth rate is used to calculate the value of cash flows beyond the last projected period and reflects management’s best estimates for perpetual growth for the reporting units. Estimates of market-participant risk-adjusted weighted average cost of capital (WACC) are used as a basis for determining the discount rates to apply to the reporting units’ future expected cash flows and terminal value.

Grainger completed the annual impairment testing using the qualitative approach for seven reporting units and the two-step quantitative test for four of these reporting units during the fourth quarter. For two of these reporting units, Grainger Lighting Services (GLS) and Grainger Brazil (GB), the two-step quantitative test indicated that the carrying value of assets exceeded the calculated fair value and step two impairment calculations were required. As part of the review of the strategic plans for GLS during the fourth quarter, Grainger evaluated the impact of planned changes to the business model and level of investment in the business. Grainger’s estimates of future projected sales growth, operating earnings, and cash flows were revised to reflect lower estimates for new customers and projects.  As a result of the lower projections, Grainger recognized impairment charges of $13 million on the GLS reporting unit.

51

During the fourth quarter, management provided strategic plans which included changes to the business model and level of investment required for GB based on insights gained from owning the business since the acquisition in the second quarter of 2012. Grainger’s assumptions were revised to reflect changes related to realization of expected deal synergies and anticipated short-term and long-term operating results of GB that were different from pre-acquisition projections. As a result of the lower performance expectations, Grainger’s estimates for future projected sales growth, operating earnings, and cash flows were revised accordingly. These lowered expectations, as well as an increase in relevant risk factors that increased the discount rate used in the calculations, resulted in the calculated fair value of GB being lower than the carrying value of assets in the step one analysis.  As a result of the completion of step two, Grainger recognized a goodwill impairment charge of $11 million.

For the two other reporting units, the fair values calculated in the step one analysis exceeded the carrying value of assets and therefore the step two calculation was not required. Fabory, with $134 million of goodwill, had a calculated fair value which exceeded the carrying value of assets by 17%. The risk of potential failure of step one of the impairment test for Fabory in future reporting periods is highly dependent upon key assumptions including the amount and timing of future expected cash flows, sales growth rates, gross margins, capital expenditures, discount rates and estimates of market-participant risk-adjusted WACC. These assumptions require considerable management judgment and are subject to uncertainty. Changes in assumptions regarding the future performance and a continued unfavorable economic environment in Europe may also have a significant impact on cash flows in the future. Given the sensitivity of the calculated fair value to changes in these key assumptions, Grainger may be required to recognize an impairment for Fabory’s goodwill in the future due to changes in market conditions or other factors related to these key assumptions.

Grainger Colombia, with $14 million of goodwill, had a calculated fair value which exceeded the carrying value of assets by 26% as of the test date.

Intangible assets included in Other assets and intangibles - net in the Consolidated Balance Sheets were comprised of the following (in thousands of dollars):

	As of December 31,
	2013						2012
	Gross carrying amount		Accumulated amortization		Net carrying amount		Gross carrying amount		Accumulated amortization		Net carrying amount

NOTE 5 - INVENTORIES

Inventories primarily consist of merchandise purchased for resale. Inventories would have been $388 million and $376 million higher than reported at December 31, 2013 and 2012, respectively, if the FIFO method of inventory accounting had been used for all Company inventories. Net earnings would have increased by $8 million, $13 million and $11 million for the years ended December 31, 2013, 2012 and 2011, respectively, using the FIFO method of accounting. Inventory values using the FIFO method of accounting approximate replacement cost. The Company provides reserves for excess and obsolete inventory. The reserve balance was $134 million and $133 million as of December 31, 2013 and 2012, respectively.

NOTE 6 - SHORT-TERM DEBT

Lines of Credit

NOTE 7 - LONG-TERM DEBT

Long-term debt consisted of the following (in thousands of dollars):

	As of December 31,
	2013			2012
Bank term loan	$	292,500		$	300,000
Euro-denominated bank term loan	158,067			158,328

Less current maturities	(30,429		)	(18,525		)
	$	445,513		$	467,048

Bank Term Loan

In May 2012, the Company entered into a $300 million, unsecured bank term loan, which matures in November 2016. The proceeds were used to refinance existing debt and for general corporate purposes. The Company may prepay the loan in whole or in part at its option. Quarterly principal payments began in August 2013.

At the election of the Company, the term loan shall bear interest at the Base Rate plus the Applicable Margin or the LIBOR Rate plus the Applicable Margin as defined within the term loan agreement. At December 31, 2013, the Company had elected a one-month LIBOR Interest Period. The weighted average interest rate during the year was 1.19%.

Euro-Denominated Bank Term Loan

In August 2011, the Company entered into a €120 million, unsecured bank term loan in connection with the acquisition of Fabory, maturing in August 2016. The Company, at its option, may prepay this term loan in whole or in part. Payments of €2.5 million are due semi-annually, beginning February 28, 2013, with the remaining balance due at maturity. The weighted average interest rate paid during the year was 1.70%. The weighted average interest rate includes inputs from variable rates and an interest rate swap. See Note 8 to the Consolidated Financial Statements.

The scheduled aggregate principal payments related to long-term debt are due as follows (in thousands of dollars):

Year	Payment Amount
2014	$	30,429
2015	35,124
2016	393,886
2017	1,392
2018	1,106
Thereafter	14,005

The Company's debt instruments include only standard affirmative and negative covenants for debt instruments of similar amounts and structure. The Company's debt instruments do not contain financial or performance covenants restrictive to the business of the Company, reflecting its strong financial position. The Company is in compliance with all debt covenants for the year ended December 31, 2013.

NOTE 8 - DERIVATIVE INSTRUMENTS

The fair values of the Company's derivative instruments are determined by using quoted market forward rates (Level 2 inputs) and reflect the present value of the amount that the Company would pay for contracts involving the same notional amounts and maturity dates.

During the fourth quarter of 2011, the Company entered into a pay-fixed / receive floating interest rate swap with a notional value of €60 million maturing in August 2016 to partially hedge the future interest expense of the euro-denominated term loan entered into to fund a portion of the Fabory acquisition. The swap is accounted for as a cash flow hedge. The effective portion of the changes in fair value of the derivative is reported as a component of other comprehensive earnings (losses) and reclassified to net income when the hedged transaction affects earnings. The value of the interest-rate swap, included on the Company's balance sheet under Employment-related and other noncurrent liabilities, was $3 million and $4 million as of December 31, 2013 and 2012, respectively.

During the fourth quarter of 2010, the Company entered into multiple foreign currency forward contracts with a total notional value of C$160 million maturing in September 2014. These forward contracts are designated and qualify as a hedge of an intercompany net investment in the Company's Canadian subsidiary. The Company uses the forward method of assessing hedge effectiveness for derivatives designated as hedging instruments of a net investment in a foreign subsidiary and all changes in fair value of the derivatives are reported as a component of other comprehensive earnings (losses), net of tax effects, as long as specific hedge accounting criteria are met. As of December 31, 2013, the foreign currency forward contracts were included on the Company's balance sheet under Prepaid expenses and other assets for $1 million. As of December 31, 2012, the foreign currency forward contracts were included on the Company's balance sheet under Employment-related and other noncurrent liabilities for $8 million.

Other foreign currency forward contracts entered into during the current and prior periods to hedge non-functional currency-denominated intercompany note receivables and forecasted U.S. dollar-denominated obligations by foreign subsidiaries of the Company were not material.

See Note 1 to the Consolidated Financial Statements for a description of the Company's Accounting Policy regarding derivative instruments and Note 13 to the Consolidated Financial Statements for additional information.

NOTE 9 - 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. This plan provides for annual employer contributions based upon a formula related primarily to earnings before federal income taxes, limited to a percentage of the total eligible compensation paid to eligible employees. The annual contribution is limited to a minimum of 8% and a maximum of 18% of total eligible compensation paid to eligible employees. The profit sharing plan expense was $173 million, $165 million and $156 million for 2013, 2012 and 2011, respectively.

The Company sponsors additional defined contribution plans available to certain U.S. and foreign employees for which contributions are paid by the Company and participating employees. The expense associated with these defined contribution plans totaled $12 million for each of the years ended December 31, 2013 and 2012 and $9 million for 2011.

Defined Benefit Plans and Other Retirement Plans

The Company sponsors a defined benefit plan which provides pension benefits for certain employees in the Netherlands. The annual pension benefit is based on 1.75 percent of a career average pay and years of service. The plan is insured and accordingly, all risks with respect to investments, mortality and longevity are covered by an insurance company. The assets of the plan are invested in a separate account with the insurer. A December 31 measurement date is utilized to value plan assets and obligations. Funding of the plan takes place through single premiums for obligations regarding future service years. As of December 31, 2013 and 2012, the pension plan was in an overfunded position with a net pension asset of $5 million and $6 million, respectively. The expense related to this plan was not significant to the Company in the past three years.

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. The cost of these programs is not significant to the Company.

Executive Death Benefit Plan

The Executive Death Benefit Plan provides one of three potential benefits: a supplemental income benefit (SIB), an executive death benefit (EDB) or a postretirement payment. The SIB provides income continuation at 50% of total compensation, payable for ten years to the beneficiary of a participant if that participant dies while employed by the Company. The EDB provides an after-tax lump sum payment of one-time final total compensation to the beneficiary of a participant who dies after retirement. In addition, pre-2008 participants may elect to receive a reduced postretirement payment instead of the EDB. Effective January 1, 2010, the plan is not available to new participants.

The net periodic benefits costs charged to operating expenses were $0.8 million in year 2013 and $1 million in 2012 and 2011. The net loss (gain) recognized in Accumulated other comprehensive earnings (AOCE) was $(1) million and $0.2 million as of December 31, 2013, and 2012, respectively. The plan benefits are paid as they come due from the general assets of the Company. The plan benefit obligation was $15 million as of December 31, 2013, and $17 million as of December 31, 2012.

56

Postretirement Benefits

The Company has a postretirement healthcare benefits plan that provides coverage for a majority of its United States 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 fourth quarter 2012, the Company implemented plan design changes effective January 1, 2013. Employees hired after January 1, 2013 are not eligible to receive retiree health benefits. Active participants in the plan as of December 31, 2012 will remain eligible for retiree health benefits with the employee contribution structure modified for certain employees based on retirement eligibility. As a result of this plan amendment, the Company's postretirement benefit obligation declined $84 million as of December 31, 2012.

During the fourth quarter 2012, the Company also implemented an Employer Group Waiver Plan (EGWP) and a secondary supplemental "wrap-around" plan for its Medicare eligible retiree medical plan participants and no longer applied for the Part D Retiree Drug Subsidy (RDS) effective January 1, 2013. The EGWP program does not alter the benefits expected to be provided to the plan participants and is expected to increase the level of Medicare subsidies that will offset plan costs. Accordingly, the event was recognized as an actuarial gain for the year ended December 31, 2012. As a result of this change, the Company's postretirement benefit obligation declined $19 million as of December 31, 2012.

The “Medicare Prescription Drug, Improvement and Modernization Act of 2003” provides a federal subsidy to retiree healthcare benefit plan sponsors that provide a prescription drug benefit that is at least actuarially equivalent to that provided by Medicare. As a result of the subsidy, the Company's postretirement benefit obligation reflected a reduction of $68 million as of December 31, 2011. As a result of the implementation of the EGWP program, the benefit obligation was no longer reduced by Part D RDS as of December 31, 2012. The subsidy reduced net periodic benefits costs by approximately $9 million and $7 million for the years ended December 31, 2012 and 2011, respectively.

The net periodic benefits costs charged to operating expenses, which were valued with a measurement date of January 1 for each year, consisted of the following components (in thousands of dollars):

	For the Years Ended December 31,
	2013			2012			2011
Service cost	$	10,589		$	20,058		$	15,762
Interest cost	8,938			12,810			13,352
Expected return on assets	(7,076		)	(6,210		)	(5,790		)
Amortization of prior service credit	(7,412		)	(495		)	(495		)
Amortization of transition asset	(143		)	(143		)	(143		)
Amortization of unrecognized losses	3,724			4,827			3,269
Net periodic benefits costs	$	8,620		$	30,847		$	25,955

The Company has elected to amortize the amount of net unrecognized gains (losses) over a period equal to the average remaining service period for active plan participants expected to retire and receive benefits of approximately 15.6 years for 2013.

Noncurrent postretirement benefit obligation	$	78,974		$	128,148

The amounts recognized in AOCE consisted of the following components (in thousands of dollars):

	As of December 31,
	2013			2012
Prior service credit	$	74,556		$	81,968
Transition asset	143			286

Deferred tax (liability)	(21,806		)	(1,618		)
Net gains	$	34,887		$	2,229

The components of AOCE related to the postretirement benefit costs that will be amortized into net periodic postretirement benefit costs in 2014 are estimated as follows (in thousands of dollars):

	2014
Amortization of prior service credit	$	(7,253	)
Amortization of transition asset	(143		)
Amortization of unrecognized losses	1,154
Estimated amount to be amortized from AOCE into net periodic postretirement benefit costs	$	(6,242	)

The benefit obligation was determined by applying the terms of the plan and actuarial models. These models include various actuarial assumptions, including discount rates, assumed 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.

58

The following assumptions were used to determine net periodic benefit costs at January 1:

	For the Years Ended December 31,
	2013		2012		2011
Discount rate	4.00	%	4.50	%	5.60	%
Expected long-term rate of return on plan assets, net of tax	6.00	%	6.00	%	6.00	%
Initial healthcare cost trend rate	8.00	%	8.50	%	9.00	%
Ultimate healthcare cost trend rate	5.00	%	5.00	%	5.00	%
Year ultimate healthcare cost trend rate reached	2019		2019		2019

The following assumptions were used to determine benefit obligations at December 31:

	2013		2012		2011
Discount rate	4.90	%	4.00	%	4.50	%
Expected long-term rate of return on plan assets, net of tax	5.70	%	6.00	%	6.00	%
Initial healthcare cost trend rate	7.50	%	8.00	%	8.50	%
Ultimate healthcare cost trend rate	4.50	%	5.00	%	5.00	%
Year ultimate healthcare cost trend rate reached	2026		2019		2019

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, 2013, the Company increased the discount rate from 4.0% to 4.9% to reflect the increase in the market interest rates which contributed to the decrease in the unrealized actuarial loss at December 31, 2013. The Company reviews external data and its own historical trends for healthcare costs to determine the healthcare cost trend rates. Grainger changed the duration of the healthcare trend rate to an assumed rate of increase of 7.5% declining 25 basis points a year until reaching the ultimate trend rate of 4.5% from an assumed rate of increase declining 50 basis points a year. This has the effect of moving the year that the ultimate trend rate is reached to 2026. Assumed healthcare cost trend rates have a significant effect on the amounts reported for the healthcare plans. A 1 percentage point change in assumed healthcare cost trend rates would have the following effects on 2013 results (in thousands of dollars):

	1 Percentage Point
	Increase		(Decrease)
Effect on total service and interest cost	$	2,205	$	(1,777	)
Effect on postretirement benefit obligation	29,776		(24,196		)

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 the net asset value of shares held by the plan in the registered investment companies at the quoted market prices (Level 1 input) as of December31 (in thousands of dollars):

	2013		2012
Registered investment companies
Fidelity Spartan U.S. Equity Index Fund	$	67,160	$	51,169
Vanguard 500 Index Fund	67,931		51,336
Vanguard Total International Stock	25,034		21,739
Total Assets	$	160,125	$	124,244

59

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. In 2013, Grainger decreased the expected long-term rate of return on plan assets from 6.0% (net of tax) to 5.7% (net of tax) based on the historical average of long-term rates of return. The required use of an expected long-term rate of return on plan assets may result in recognition of income that is greater or less 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 (which include a projection for expected future employee service) for the next ten years (in thousands of dollars):

Year	Estimated Gross Benefit Payments
2014	$	5,299
2015	6,075
2016	6,952
2017	8,001
2018	9,159
2019-2023	$	65,751

NOTE 10 - LEASES

The Company leases certain land, buildings and equipment under noncancellable operating leases that expire at various dates through 2036. Capital leases as of December 31, 2013 are not considered material. 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.

At December 31, 2013, the approximate future minimum lease payments for all operating leases were as follows (in thousands of dollars):

Year	Future Minimum Lease Payments
2014	$	67,993
2015	56,697
2016	41,232
2017	27,657
2018	17,128
Thereafter	19,937
Total minimum payments required	230,644
Less amounts representing sublease income	(4,353		)
	$	226,291

Rent expense, including items under lease and items rented on a month-to-month basis, was $68 million for 2013 and 2012, and $72 million for 2011. These amounts are net of sublease income of $1 million for 2013 and 2012, and $2 million for 2011.

NOTE 11 - STOCK INCENTIVE PLANS

The Company maintains stock incentive plans under which the Company may grant a variety of incentive awards to employees and directors. In 2010, the Company's shareholders approved the 2010 Incentive Plan (Plan), which replaced all prior active plans (Prior Plans). Awards previously granted under Prior Plans will remain outstanding in accordance with their terms. A total of 5.9 million shares of common stock were reserved for issuance under the Plan. As of December 31, 2013, there were 1.9 million shares available for grant under the Plan. Non-qualified stock options, performance shares, restricted stock units and deferred stock units have been granted and are outstanding under these plans.

Pretax stock-based compensation expense was $52 million, $53 million and $51 million in 2013, 2012 and 2011, respectively. Related income tax benefits recognized in earnings were $17 million in 2013 and $18 million in 2012 and 2011.

Options

In 2013, 2012 and 2011, the Company issued stock option grants to employees as part of their incentive compensation. Option awards are granted with an exercise price equal to the closing market price of the Company's stock on the last trading day preceding the date of grant. The options generally vest over three years, although accelerated vesting is provided in certain circumstances. Awards generally expire 10 years from the grant date. Transactions involving stock options are summarized as follows:

	Shares Subject to Option		Weighted Average Price Per Share		Options Exercisable
Outstanding at January 1, 2011	4,881,248		$	77.61	2,486,478

The Company uses a binomial lattice option pricing model for the valuation of stock options. The weighted average fair value of options granted in 2013, 2012 and 2011 was $51.30, $43.98 and $33.95, respectively. The fair value of each option granted in 2013, 2012 and 2011 used the following assumptions:

	For the years ended December 31,
	2013	2012	2011
Risk-free interest rate	0.9%	1.1%	2.6%
Expected life	6 years	6 years	6 years
Expected volatility	25.5%	25.9%	24.6%
Expected dividend yield	1.5%	1.6%	1.8%

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 also the primary basis for selection of expected dividend yield assumptions.

Performance Shares

The Company awards performance-based shares to certain executives. Receipt of Company stock is contingent upon the Company meeting sales growth and return on invested capital (ROIC) performance goals. Each participant is granted a base number of shares. At the end of the performance period, the number of shares granted will be increased, decreased or remain the same based upon actual Company-wide sales versus target sales. The shares, as determined at the end of the performance period, are issued at the end of the third year if the Company's average target ROIC is achieved during the vesting period.

Performance share value is based upon closing market prices on the last trading day preceding the date of award and is charged to earnings on a ratable basis over the three-year period based on the number of shares expected to vest. Holders of performance share awards are not entitled to receive cash payments equivalent to cash dividends. If the performance shares vest, they will be settled by the Company's issuance of common stock in exchange for the performance shares on a one-for-one basis. The following table summarizes the transactions involving performance-based share awards:

	2013				2012				2011
	Shares		Weighted Average Price Per Share		Shares		Weighted Average Price Per Share		Shares		Weighted Average Price Per Share
Beginning nonvested shares outstanding	117,979		$	141.86	192,740		$	109.16	177,120		$	84.74

At December 31, 2013, there was $5 million of total unrecognized compensation expense related to performance-based share awards that the Company expects to recognize over a weighted average period of 1.7 years.

Restricted Stock Units (RSUs)

RSUs granted vest over periods from three to seven years from issuance, although accelerated vesting is provided in certain instances. Holders of RSUs are entitled to receive 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:

	2013				2012				2011
	Shares		Weighted Average Price Per Share		Shares		Weighted Average Price Per Share		Shares		Weighted Average Price Per Share
Beginning nonvested units	978,888		$	118.60	1,119,488		$	100.76	1,205,787		$	88.65

Director Stock Awards

The Company's Board of Directors receives both cash and deferred stock units (DSUs) for its services.  A DSU is the economic equivalent of a share of common stock.  The directors were each awarded $125,000 of DSUs in 2013 and $115,000 in 2012 and 2011.  The number of units granted was based on the 200-day average stock price as of January 31 of the grant year. Compensation expense related to the DSUs is based upon the closing market price on the last trading day preceeding the date of award.  DSUs vest immediately at grant and are entitled to receive dividends and other distributions with respect to common stock, which are deferred as stock units, based on the market value of the stock at relevant times. Directors can also elect to defer their cash fees in the form of DSUs. Settlement of DSUs is required to be deferred until after termination of service as a director.  The accumulated value of DSUs is recorded in Additional contributed capital as of December 31, 2013 and 2012.  During 2012, the Board approved a change in the settlement procedure to eliminate the cash settlement option. As of December 31, 2011, the outstanding DSUs were recorded as a liability in Employment-related and other noncurrent liabilities and the Company recognized expense for appreciation in value of equivalent stock units based on the market price of the Company’s common stock in 2012 and 2011. The following table summarizes DSU activity (dollars in thousands):

NOTE 14 - INCOME TAXES

The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities, using enacted tax rates in effect for the year in which the differences are expected to reverse.

Income tax expense consisted of the following (in thousands of dollars):

	For the Years Ended December 31,
	2013			2012		2011

Noncurrent assets	16,209			51,536
Noncurrent liabilities (foreign)	(68,431		)	(75,437		)
Net deferred tax asset	$	23,597		$	32,066

At December 31, 2013, the Company had $262 million of operating loss carryforwards related primarily to foreign operations. Some of the operating loss carryforwards may expire at various dates through 2023. The Company has recorded a valuation allowance, which represents a provision for uncertainty as to the realization of the tax benefits of these carryforwards. In addition, the Company recorded a valuation allowance to reflect the estimated amount of deferred tax assets that may not be realized.

The changes in the valuation allowance were as follows (in thousands of dollars):

	For the Years Ended December 31,
	2013		2012
Beginning balance	$	54,434	$	53,739
Increase related to foreign net operating loss carryforwards	8,391		695
Ending balance	$	62,825	$	54,434

A reconciliation of income tax expense with federal income taxes at the statutory rate follows (in thousands of dollars):

	For the Years Ended December 31,
	2013			2012			2011
Federal income tax at the 35% statutory rate	$	450,660		$	391,226		$	368,034
State income taxes, net of federal income tax benefit	27,430			26,099			32,226
Other - net	1,760			1,615			(15,145		)
Income tax expense	$	479,850		$	418,940		$	385,115
Effective tax rate	37.3		%	37.5		%	36.6		%

In 2011, other - net included the tax benefit related to settlement of various tax reviews during 2011 and the benefit of tax law changes in Japan enacted in the fourth quarter of 2011.

Undistributed earnings of foreign subsidiaries at December 31, 2013, amounted to $386 million. No provision for deferred U.S. income taxes has been made for these subsidiaries because the Company intends to permanently reinvest such earnings in its foreign operations. If at some future date these earnings cease to be permanently invested, the Company may be subject to U.S. income taxes, foreign withholding, and other taxes on such amounts, which cannot be reasonably estimated at this time.

The changes in the liability for tax uncertainties, excluding interest, are as follows (in thousands of dollars):

	2013			2012
Balance at beginning of year	$	40,937		$	22,760
Additions to tax positions related to the current year	8,396			11,369
Additions for tax positions of prior years	2,308			8,977
Reductions for tax positions of prior years	(7,242		)	(1,447		)
Reductions due to statute lapse	(18		)	(737		)
Settlements, audit payments, refunds - net	(4,064		)	15
Balance at end of year	$	40,317		$	40,937

The Company classifies the liability for tax uncertainties in Deferred income taxes and tax uncertainties. Included in this amount are $8 million and $6 million at December 31, 2013 and 2012, 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. The reduction to tax positions of prior years in 2013 related primarily to law changes, conclusion of audits and audit settlements.

The Company regularly undergoes examination of its federal income tax returns by the Internal Revenue Service (IRS). The Company's federal tax returns for 2009 and 2010 are currently under audit by the IRS, and the tax years 2011 through 2013 are open. The Company is also subject to audit by state, local and foreign taxing authorities. Tax years 2002 - 2013 remain subject to state and local audits and 2006 - 2013 remain subject to foreign audits. The estimated amount of liability associated with the Company's uncertain tax positions 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 in the provision for income taxes. During 2013 and 2012, the Company recognized an expense of $2 million and $1 million, respectively. During 2011, the Company recognized a net benefit of $1 million, primarily due to settlement of audits and a statute lapse. As of December 31, 2013 and 2012, the Company accrued approximately $4 million and $2 million, respectively, for interest.

NOTE 15 - EARNINGS PER SHARE

The Company’s unvested Restricted Stock Units and Directors' Deferred Stock Units 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 is 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 thousands of dollars, except for share and per share amounts):

	For the Years Ended December 31,
	2013			2012			2011
Net earnings attributable to W.W. Grainger, Inc. as reported	$	797,036		$	689,881		$	658,423

NOTE 16 - SEGMENT INFORMATION

The Company has two reportable segments:  the United States and Canada.  The United States operating segment reflects the results of the Company’s U.S. business.  The Canada operating segment reflects the results for Acklands – Grainger Inc., the Company’s Canadian business.  Other businesses include the Company's operations in Europe, Asia, Latin America and other U.S. operations. These businesses individually do not meet the criteria of a reportable segment. Operating segments generate revenue almost exclusively through the distribution of maintenance, repair and operating supplies, as service revenues account for less than 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.

Following is a summary of segment results (in thousands of dollars):

NOTE 18 - CONTINGENCIES AND LEGAL MATTERS

The Company has 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 purportedly distributed by the Company. In 2013, the Company was named in lawsuits relating to asbestos involving approximately 70 new plaintiffs, and lawsuits relating to asbestos and/or silica involving approximately 67 plaintiffs were dismissed with respect to the Company, typically based on the lack of product identification.

As of January 23, 2014, the Company is named in cases filed on behalf of approximately 1,929 plaintiffs in which there is an allegation of exposure to asbestos and/or silica. The Company has denied, or intends to deny, the allegations in all of the above-described lawsuits.  If a specific product distributed by the Company is identified in any of these lawsuits, the Company would attempt to exercise indemnification remedies against the product manufacturer.  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, coverage and costs of defense of lawsuits involving claims of exposure to asbestos.  While the Company is unable to predict the outcome of these lawsuits, 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.

As previously disclosed, on December 26, 2012, the Company announced that it entered into a definitive settlement agreement (the “Agreement”) with the United States of America, acting through the Civil Division of the United States Department of Justice (DOJ) of certain claims related to its contracts with the General Services Administration (GSA) and the United States Postal Service. The Agreement did not contain any admission of wrongdoing by the Company. The amounts due under the Agreement have been fully paid. The Company continues to maintain a $6 million reserve for liabilities associated with alleged claims for tax, freight and billing errors related to its GSA contract that were not covered by the Agreement and which remain unresolved.

From time to time the Company is involved in various other legal and administrative proceedings that are incidental to its business, including claims related to product liability, general negligence, contract disputes, environmental issues, 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 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.

Exhibit 10b(ix)

Summary Description of the 2014 Directors Compensation Program

Members of the Company’s Board of Directors who are not Company employees receive an annual retainer of $85,000, which is intended to cover all regularly scheduled meetings of the Board and its committees. If additional meetings are held, a per-meeting fee of $1,500 will be paid to each attending director.

The Chairs of Board committees receive additional annual retainers. For the Chair of the Audit Committee, the retainer is $20,000; for the Chair of the Board Affairs and Nominating Committee, the retainer is $10,000; and for the Chair of the Compensation Committee, the retainer is $15,000. The retainer for the Lead Director is $20,000.

All independent directors also receive an annual deferred stock unit grant. The number of shares covered by each grant is equal to $125,000 (based on the 200-day average stock price as of January 31, in the year of the grant, a methodology consistent with the calculation for other executive equity awards), rounded up to the next ten-share increment. The deferred stock units are settled upon termination of service as a director. Directors may also defer their annual retainers, committee chair retainers, and meeting fees in a deferred stock unit account.

A director who is an employee of Grainger or any Grainger subsidiary does not receive any retainer fees for Board or Board committee service, Board or Board committee meeting attendance fees, or stock options or stock units under the Director Stock Plan.

Stock ownership guidelines applicable to non-employees directors were established in 1998. These guidelines provide that within five years after election, a director must own Grainger common stock and common stock equivalents having a value of at least five times the annual retainer fee for serving on the Board.

Exhibit 10(b)(xxiii)

W.W. GRAINGER, INC.

PERFORMANCE SHARE AWARD AGREEMENT

This Performance Share Award Agreement (this “Agreement”) is entered into as of January 1, 2013 between W.W. Grainger, Inc., an Illinois corporation (the “Company”) and the undersigned Company executive (the “Executive”).

Pursuant to the W.W. Grainger, Inc. 2010 Incentive Plan (the “Plan”), the Company desires to award to the Executive as hereinafter provided certain performance shares (the “Performance Shares”), entitling the Executive to receive shares of the Company’s common stock (“Common Stock”) based upon the Company’s attainment of certain long-term performance goals. This award of Performance Shares is in consideration of the Executive’s agreement to enter into an Unfair Competition Agreement (the “Unfair Competition Agreement”) between the Company and the Executive concurrently with this Agreement. In turn, the Executive desires to enter into the Unfair Competition Agreement and accept the award of Performance Shares, on the terms and conditions set forth in this Agreement, the Plan and the Unfair Competition Agreement. Capitalized terms used but not defined in this Agreement have the meanings specified in the Plan.

NOW, THEREFORE, in consideration of the mutual promises set forth below and in the Unfair Competition Agreement, the parties hereto agree as follows:

1. General. This award is governed by and subject to the terms and conditions of this Agreement, the Plan and the Unfair Competition Agreement (the terms of which are hereby incorporated herein by reference). In general, the Executive will be entitled to receive a number of Performance Shares determined by the Company’s performance against its sales growth target (as described in Section 2 below), with the vesting of those Performance Shares being subject to the Company’s achievement of its return on invested capital target (as described in Section 3 below).

2. Grant of Performance Shares; 2015 Sales Target. The Company hereby awards to the Executive a total of _______ Performance Shares (the “Target Number”), such number being subject to possible adjustment as follows. The actual number of Performance Shares which the Executive will receive will depend on the Company’s total net sales during its 2015 fiscal year. Such number will be calculated in accordance with the following table:

If, the Company’s 2015 sales are at:	Then the number of Performance Shares will be:
Less than $9.5 Billion	Zero (0)
$9.5 Billion	Fifty percent (50%) of the Target Number
$11.3 Billion	One hundred percent (100%) of the Target Number
$11.9 Billion or more	Two hundred percent (200%) of the Target Number

Amounts between the foregoing numbers will be interpolated as necessary. For example, if 2015 net sales are $10.4 Billion, then the Executive would receive seventy-five percent (75%) of the Target Number of Performance Shares.

3. Vesting; ROIC Target. The vesting of the Performance Shares will depend upon the Company’s average return on invested capital (“ROIC”) during the period of three fiscal years beginning with the 2013 fiscal year, i.e., the Company’s 2013, 2014 and 2015 fiscal years (the “Measuring Period”). For this purpose, ROIC means the Company’s operating earnings divided by its net working assets. Vesting will be determined in accordance with the following table:

If the Company’s average ROIC during the Measuring Period is:	Then the following percentage of Performance Shares will vest:
Less than eighteen percent (18%)	Zero (0)
Eighteen percent (18%) or more	One hundred percent (100%)

Amounts between the foregoing numbers will not be interpolated. In other words, the Performance Shares will either vest at one hundred percent (100%) or they will not vest at all. If the Performance Shares vest, then in settlement of the Performance Shares, the Executive will receive a number of shares of Common Stock equal to the number of Performance Shares determined under Section 2 above, subject, however, to the withholding provisions below. If the Performance Shares do not vest, then they will be forfeited in full and the Executive shall have no further rights with respect to the award hereunder.

4. Receipt by the Executive of the Plan. The Executive acknowledges receipt of the Plan booklet which contains the entire Plan. The Executive represents and warrants that he has read the Plan and that he agrees that all Performance Shares awarded under it shall be subject to all of the terms and conditions of the Plan, including but not limited to the exclusive right of the Committee to interpret and determine the terms and provisions of the Performance Share Award Agreements and the Plan and to make all determinations necessary or advisable for the administration of the Plan, all of which interpretations and determinations shall be final and binding. Without limiting the generality of the foregoing, the Committee shall have the discretion to adjust the terms and conditions of awards of Performance Shares to correct for any windfalls or shortfalls in such awards which, in the Committee’s determination, arise from factors beyond the awardees’ control, provided, however, that the Committee’s authority with respect to any award to a “covered employee,” as defined in Section 162(m)(3) of the Code, shall be limited to decreasing, and not increasing, such award.

5. Tax Withholding Obligations. If the Performance Shares shall vest, the Executive shall be responsible for any required withholding including, but without limitation, taxes, FICA contributions, or the like under any federal, state or applicable statute, rule, or regulation. Upon such vesting, the Company may withhold a number of shares of Common Stock having a fair market value on the date that the amount is to be withheld equal to the amount determined by the Company to be the required statutory minimum withholding; this amount may or may not satisfy the Executive’s calendar year withholding obligation. The Company shall not issue and shall not deliver any of its Common Stock upon the vesting and settlement of the Performance Shares until and unless the proper provision for minimum required withholding has been made.

6. Recoupment of Incentive-based Compensation.

a. If the Board of Directors determines that the Executive has committed fraud against the Company or has been engaged in any criminal conduct that involves or is related to the Company and such Executive is entitled to receive performance shares, stock options, restricted stock units or cash incentive compensation (“Incentive Compensation”) then the Company shall recover from the Executive such Incentive Compensation, in whole or in part, for any period of time, as it deems appropriate under the circumstances. The Board shall have sole discretion in determining whether the Executive’s conduct was in compliance with the law or Company policy and the extent to which the Company will seek recovery of the Incentive Compensation notwithstanding any other remedies available to the Company. If the Executive engages in misconduct or is believed to have engaged in misconduct, the Company shall be entitled to recover from the Executive, and the Executive shall re-pay awards received pursuant to this Program, in whole or in part, for any period of time, as the Company deems appropriate under the circumstances.

b. In the event of a restatement of materially inaccurate financial results, the Board has the discretion to recover cash incentive payments or the settlement of performance shares (“Incentive Payments”) that were paid or settled to the Executive during the period covered by the restatement as set forth herein. If the payment or settlement of Incentive Payments would have been lower had the achievement of applicable financial performance goals been calculated based on such restated financial results, the Board may, if it determines appropriate in its sole discretion, recover the portion of the paid or settled Incentive Payments in excess of the payment or settlement that would have been made based on the restated financial results. The Company will not seek to recover Incentive Payments received or settled more than three years after the date of the initial filing that contained the incorrect financial results.

7. Other Terms and Conditions Applicable to the Performance Shares.

a. Rights of Shareholder. The Executive shall not have any voting rights with respect to the Performance Shares. The Executive shall have no right to receive dividend equivalent payments with respect to the Performance Shares.

b. Termination of Employment. If the Executive’s employment terminates during the Measuring Period for any reason other than retirement, disability or death, then the Performance Shares will be forfeited in full and the Executive shall have no further rights with respect to the award hereunder. If the Executive engages in misconduct, or is believed to have engaged in misconduct all awards will be forfeited.

c. Retirement/Death. If the Executive’s employment with the Company terminates during the Measuring Period by reason of retirement or death, then the Executive or the Executive’s estate will be entitled to receive in settlement of the Performance Shares a number of shares of Common Stock equal to the product of (x) the number of Performance Shares, if any, which subsequently vest under Section 3 above, multiplied by (y) a fraction, the numerator of which is the number of months during the Measuring Period that the Executive was employed by the Company and the denominator of which is the total number of months in the Measuring Period, i.e., 36 months. For purposes of the foregoing calculation, the Executive will be deemed to have been employed by the Company during the month that his employment terminates if, and only if, such termination occurs on or after the fifteenth (15^th) calendar day of that month.

d. Disability. If the Executive’s employment with the Company terminates during the Measuring Period by reason of disability (defined below), then the Executive will be entitled to receive in settlement of the Performance Shares a number of shares of Common Stock calculated in the same manner as under Subsection c immediately above, provided, however, that if such termination of employment occurs during the first fiscal year of the Measuring Period, then for purposes of such calculation the number of Performance Shares referred to in clause (x) of such calculation shall be determined as though the Company had met, but not exceeded, its sales growth target and 100 percent of such Performance Shares had vested. For purposes of the foregoing, the term “disability” means the Executive’s inability to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment that can be expected to result in death or that has lasted for a continuous period of not less than twelve (12) months.

8. Severability. The provisions of the Agreement shall be severable, and in the event that any provision of it is found to be unenforceable, all other provisions shall be binding and enforceable on the parties as drafted. In the event that any provision is found to be unenforceable, the parties consent to the Court’s modification of that provision in order to make the provision enforceable, subject to the limitations of the Court’s powers under the law.

9. Venue. The Executive acknowledges that, in the event that a determination of the enforceability of this Agreement is sought, or any other judicial proceedings are brought pertaining to this Agreement, the Company has the choice of venue and the preferred venue for such proceedings is Cook County, Illinois.

10. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Illinois, excluding any conflicts or choice of law rules or principles thereof.

IN WITNESS WHEREOF, the Company has caused this Performance Share Award Agreement to be executed by a duly authorized Officer of the Company and the Executive hereby agrees to all the terms and conditions set forth above.

SEPARATION AGREEMENT AND GENERAL RELEASE

This Separation Agreement and General Release (“Agreement”) is made and entered into this 4^th day of October, 2013 by and between W.W. Grainger, Inc. (“Grainger”) and Michael Pulick (the “Officer”). The Officer understands and voluntarily enters into this Agreement with Grainger and, in consideration of the Separation Payments and benefit continuation described herein, agrees as follows:

1. Resignation as Officer; Separation Date. The Officer hereby acknowledges that he has voluntarily resigned effective August 31, 2013 (the “Resignation Date”) as an Officer of Grainger and of all corporations that are direct or indirect subsidiaries of or otherwise affiliated with Grainger (“Affiliates”), and as trustee, member or fiduciary of all trusts, committees or similar bodies of or otherwise affiliated with Grainger and the Affiliates. In an effort to provide for an orderly transition, the Officer has agreed to continue providing ongoing services at his current rate of pay to Grainger for purposes associated with role and activity transition during the period of September 1, 2013 through December 31, 2013 (the “Separation Date”).

2. Separation Payments. During the formal Compensation Continuation period beginning January 1, 2014 and extending through December 31, 2015, the Officer shall be paid on a pro-rata basis in an amount representing the equivalent of eighteen (18) months of pay at the Officer’s current base pay rate. Each payment shall be paid in an equal bi-weekly installment amount less required deductions through December 31, 2015 (the “Termination Date”). No Separation Payments shall be made to the Officer until at least the eight (8^th) day following the day on which the Officer signs this Agreement, and provided that the Agreement is not revoked by the Officer pursuant to Section 22 prior to that date.

3. Benefits.

a. Health, Dental, Life and Vision. To the extent that the Officer currently participates, Grainger will continue to provide, through deductions from the Officer’s Separation Payments at the same rate paid by employees, group health, dental and vision benefits and life insurance as currently maintained for the Officer, or as subsequently modified by Grainger, through the Termination Date. Dental benefits, health benefits and group life insurance will terminate earlier, however, on the date that the Officer becomes eligible for benefit coverage through a subsequent employer. After the Officer’s benefit coverage ceases on December 31, 2015, the Officer may elect to continue group health and dental benefits under COBRA.

b. Profit Sharing. For the 2013, 2014 and 2015 plan years, the Officer will be eligible to share in contributions under the W.W. Grainger, Inc. Employees Profit Sharing Plan (“PST”) and the W.W. Grainger, Inc. Supplemental Profit Sharing Plan (“SPSP”). The Separation Payments received in such plan years, including in the case of the 2013 plan year, the MIP payment described in Section 3(e) below, will be included for purposes of determining the amount of the Officer’s contributions under the PST (to the extent permitted by applicable law) and SPSP. To the extent that the Officer is not permitted to share in PST contributions under the terms of the PST, such amounts shall be contributed to the SPSP in addition to funds otherwise allocated to the Officer under the SPSP. After the Termination Date, the Officer will be eligible for distribution of his vested funds in accordance with the terms of PST and SPSP applicable to Plan participants.

c. Unemployment Benefits. The Officer agrees that he will not apply for unemployment benefits while he continues to receive Separation Payments through the Officer’s Termination Date or at any time in the future that would otherwise be chargeable to Grainger’s unemployment insurance account. Any amounts of unemployment insurance benefits received by the Officer shall offset the Officer’s Separation Payments.

d. PTO Time. The Officer understands that he will not be eligible for or accrue any additional PTO eligibility after the Separation Date. Payment for any earned but unused PTO will be incorporated in Officer’s Compensation Continuation payments as previously referenced in Paragraph 2 above in an effort to enhance the value of each payment.

e. Management Incentive Program (MIP). As an additional Separation Payment to those provided for in Section 2 hereof, the Officer will participate in the 2013 MIP. For such period, the Officer’s payment shall be based upon the Officer’s current salary, target percentage level and Company performance. This payment will be made to Officer during the first quarter of 2014, when executive MIP bonuses are paid. Officer will not be eligible for any MIP or other cash incentive award other than the above referenced amounts or for any other periods following the Separation Date.

f. Career Continuation - Outplacement Assistance. Officer shall be eligible to receive professional Career Continuation - Outplacement services at Grainger’s expense. Officer may interview and then select a service provider from those designated firms made available to him for this purpose by Grainger.

g. Tax Preparation - Financial Planning. The Officer will be reimbursed up to a maximum of $10,000.00 for professional tax preparation and financial planning assistance associated with the preparation of his 2013 tax year filings. The Officer shall not receive any tax preparation allowance beyond those referenced above.

h. Deferred Compensation / Deferred Stock. Exercisable and payable according to the Program’s provisions (timing 6 months after Termination Date). All deferred Compensation and Deferred Stock shall become payable and or exercisable six (6) months after my Termination Date pursuant to the provisions of the Program then in effect.

i. Cessation of Benefits. All other benefits and the Officer’s eligibility to participate in any other Grainger employee programs will cease as of the Separation Date, except as provided or referenced in this Agreement. The amounts and benefits payable to the Officer under this Agreement shall be in lieu of any amounts or benefits otherwise provided under any severance plan or policy of Grainger.

4. Stock Options, Restricted Stock Units and Performance Shares. The Officer will be eligible to exercise all vested stock options pursuant to the terms of the W.W. Grainger, Inc. 2010 Incentive Plan and companion agreements. Options will continue to vest through the Termination Date, with any remaining unvested options forfeiting as of the same Termination Date. Thereafter, all options must be exercised on or before the expiration date of each option or within three (3) months of the Officer’s Termination Date, whichever should occur first. The Officer further understands and agrees that the non-competition provisions of restricted stock unit and/or stock option agreements to which the Officer is a party, which provisions are incorporated herein by reference, including without limitation the W.W. Grainger, Inc. Unfair Competition Agreement dated April 24, 2013, and the W.W. Grainger, Inc. Performance Share Agreement dated January 1, 2013 (collectively, the “non-competition provisions”), will remain in full force and effect, and are in addition to and not superseded by any other obligation set forth in this Agreement. The Officer acknowledges and agrees that, for purposes of such agreements, the Officer’s employment with Grainger shall be considered terminated on the Termination Date hereunder, and the term “Date of Termination” as used in the Unfair Competition Agreement dated April 24, 2013, shall mean the Termination Date hereunder. The Officer understands that he will not be eligible for any further grants of stock options beyond those he has already received.

Officer shall not be eligible to receive any Performance Share Awards after January 1, 2013. All existing Performance Share awards shall be governed and vest according to the terms established under the Grainger Performance Share Program including Officer’s January 2013 award which is currently scheduled to vest on December 31, 2015.

5. General Release and Waiver of Claims. In exchange and in consideration for the promises, obligations, and agreements undertaken by Grainger herein, which the Officer agrees and acknowledges are adequate and sufficient consideration, the Officer, on behalf of himself, his spouse, agents, representatives, attorneys, assigns, heirs, executors, administrators, and other personal representatives, releases and forever discharges Grainger, the Affiliates, and all of their officers, employees, directors, agents, attorneys, personal representatives, predecessors, successors, and assigns (hereinafter collectively referred to as the “Releasees”) from any and all claims of any kind which he has, or might have, as of the date of this Agreement; or which are based on any facts which exist or existed on or before the date of this Agreement. The claims the Officer is releasing include, but are not limited to, all claims relating in any way to his employment at Grainger or his separation from that employment; and all claims under Title VII of the Civil Rights Act of 1964, the Civil Rights Act of 1991, 42 U.S.C. § 1981, the Equal Pay Act, the Employee Retirement Income Security Act, the Americans with Disabilities Act, the Federal Rehabilitation Act, the Age Discrimination in Employment Act (“ADEA”), the Older Worker Benefit Protection Act, the Illinois Human Rights Act, the Illinois Wage Payment and Collection Act, or any other federal, state or local law relating to employment, discrimination, retaliation, or wages, or under the common law of any state (including, without limitation, claims relating to contracts, wrongful discharge, retaliatory discharge, defamation, intentional or negligent infliction of emotional distress, and wrongful termination of benefits). The Officer also releases and forever discharges Grainger and all other Releasees from any and all other demands, claims, causes of action, obligations, agreements, promises, representations, damages, suits, and liabilities whatsoever, both known and unknown, in law or in equity, which he has or might have as of the date of this Agreement. The Officer understands that this Section 5 of this Agreement contains a complete and general release of any claim that he now has against Grainger and all other Releasees, or could ever have against Grainger and all other Releasees, based on any fact, event, or omission that has occurred up to the time at which he signs the Agreement.

The Officer does not intend to nor is he waiving any rights or claims that may arise after the date that he signs this Agreement, or any right on the Officer’s part to challenge the knowing and voluntary nature of this release with respect to claims under ADEA. Notwithstanding the foregoing, the Officer does not waive any rights he may have to benefits available during the period of transition or after termination under any company-sponsored employee benefit plan, or any rights he may have to insurance protection and/or indemnification for actions taken by the Officer while an employee and Officer of Grainger including the transition period of September 1, 2013 through December 31, 2013. The Officer acknowledges that this is an individually negotiated agreement and he agrees that his termination of employment with Grainger is not pursuant to an employment termination program as that term is used in the ADEA.

Excluded from this General Release and Waiver are any claims or rights which Officer cannot waive by law, including workers’ compensation claims, as well as any claims for breach of this Agreement. Also excluded from this Agreement are Officer’s rights to file a charge with the Equal Employment Opportunity Commission or any other federal, state or local agency, and to participate in an agency investigation. Officer, however, waives all rights to recover money or other individual relief if any administrative agency or another person or entity pursues any claim on Officer’s behalf arising out of or related to Employee’s employment with Grainger. Officer represents that there is no lawsuit or other claim against Grainger pending by him in any federal, state, or municipal court or other tribunal which has not been addressed herein.

The Officer understands and agrees that this waiver and release is an essential and material term of this Agreement and that, without such provision, no agreement would have been reached by the parties.

6. Covenant Not to Sue. The Officer agrees not to pursue or permit to be filed or pursued against Grainger or any Releasee, any claim or action before any federal, state, or local, administrative, legislative or judicial body based on any claim or liability described in the foregoing section, or otherwise related in any way to the Officer’s employment with Grainger, and understands that the purpose of this waiver and release is to dispose of, with finality, any claims that the Officer may have against Grainger and all other Releasees so that there will be no disputes or controversies concerning any matters following the Resignation Date. The Officer has no such claim or lawsuit outstanding at this time, and the Officer does not know of any such potential claim or lawsuit that may be asserted by the Officer or any other person in connection with the Officer’s employment with Grainger. The Officer understands that the terms of this section do not apply to a challenge to the knowing and voluntary nature of this release with respect to claims under ADEA.

7. Unfair Competition.

a. The Officer acknowledges that in connection with the performance of his duties for Grainger, he has created, used or accessed confidential and trade secret information of Grainger and the Affiliates (as further described in Section 11 below). The Officer further acknowledges that his employment with or other work on behalf of a Competitor (defined in Section 7(b) below) would necessarily and inevitably lead to his unauthorized use or disclosure of such confidential and trade secret information. Accordingly, the Officer agrees that for a period beginning on the date hereof and continuing until the second anniversary of the Termination Date, and within one hundred (100) miles of any branch, office or distribution center of Grainger or an Affiliate to which he was assigned either physically or electronically within two years prior to ceasing active employment with the Company, as well as on behalf of any Competitor specifically identified on Exhibit A, anywhere in the nation (the “Restricted Area”), he will not directly or indirectly, whether as executive, officer, director, owner, shareholder, partner, associate, consultant, advisor, contractor, joint venturer, manager, agent, representative or otherwise, work for a Competitor at said location or within the above designated 100 mile radius in any capacity that would involve:

i. the same or substantially similar functions or responsibilities to those the Officer performed for Grainger within two years of the Separation Date; or

ii. supervision over the same or substantially similar responsibilities to those the Officer performed for Grainger within two years of the Separation Date; or

iii. assisting a Competitor in decisions that involve or affect the same or a substantially similar area of operations to those the Officer was involved in with Grainger within two years of the Separation Date.

The Officer may not circumvent the purpose of this restriction by engaging in business within the Restricted Area through remote means such as telephone, correspondence, electronic or any other form of computerized communication.

b. A “Competitor” is any person or legal entity or branch, office or operation thereof (a “Firm”) that engages in business that is competitive with the business activities of Grainger through, but not limited to: (i) selling maintenance, repair and operating (MRO) supplies to North American or applicable Global businesses; (ii) providing indirect materials management services to North American or applicable Global businesses; (iii) aggregating information regarding indirect materials for the purpose of conducting business-to-business Internet commerce with North American or applicable Global businesses; or (iv) indirect materials procurement services to North American or applicable Global businesses. Without limiting the generality of the foregoing, each of the Firms identified on Exhibit A hereto constitutes a Competitor.

c. A Firm shall not be deemed a Competitor unless the aggregate revenue of such Firm for its most recently completed fiscal year that is attributable to the categories of products and services set forth in clauses (i) through (iv) of Section 7(b) above equals more than 5% of the aggregate amount of consolidated revenue that Grainger derived from such categories of products and services during its most recently completed fiscal year.

d. The Officer may at any time, or from time to time, request Grainger to advise the Officer in writing whether or not Grainger considers a specified Firm to be a Competitor. Any such request shall be made by written notice to Grainger that includes: (i) the name of the specific business unit for which the Officer proposes to work; (ii) the name or names of any parent companies of such business unit; (iii) a description of the specific services which the Officer proposes to perform for such business unit; (iv) a statement as to why the Officer believes that the performance of such services will not adversely affect Grainger’s legitimate protectible interests; and (v) the requested date of Grainger’s response (which date shall be at least 30 days after the date of Grainger’s receipt of the Officer’s request). Grainger agrees to consider any such request in good faith and to respond to such request before the requested date, but in no event later than 45 days after Grainger’s receipt of the officer’s request.

e. The Officer specifically recognizes and affirms that Section 7(a) is a material and important term of this Agreement. If any court of competent jurisdiction determines that the covenant set forth in Section 7(a), or any part thereof, would be unenforceable due to the stated duration or geographical scope of such covenant, such court shall have the power to reduce the duration or scope of such provision, as the case may be, and, as so reduced, such provision shall then be enforceable. If the court does not modify such provision as aforeseaid, or if the provision is otherwise held or found invalid or unenforceable for any reason whatsoever, then (without limiting any other remedies which may be available to Grainger under this Agreement or otherwise, including, without limitation, Section 13 hereof), Grainger shall be entitled to cease making payments and furnishing benefits to the Officer pursuant to this Agreement and shall be further entitled to receive from the Officer reimbursement of all Separation Payments and other payments and benefits theretofore furnished to the Employee pursuant to this Agreement.

Pending such reimbursement, and without limiting Grainger’s rights under Section 13 hereof or any other rights and remedies of Grainger, Grainger shall have the right to offset the amount of such reimbursement against any amount or benefit otherwise payable to the Officer.

8. Non-Disparagement. The Officer agrees to take no action in derogation or disparagement of Grainger or the Affiliates, or their respective businesses or strategic interests, or the Releasees. The Officer further agrees not to discuss in a negative manner or otherwise negatively comment on Grainger or any Affiliate, or their respective businesses or strategic interests, or the Releasees, in public, for publication on electronic media (including but not limited to chat rooms, message boards, or the like), in similar public forums, or otherwise, other than communication of publicly available information. In turn, Grainger agrees that its Senior Officers will make no public statements nor sanction any action in derogation or disparagement of the Officer.

9. Non-Interference with Business Relationships. The Officer agrees not to interfere with the employment of any Grainger employee or otherwise with the business relationships of Grainger, and to the extent required to enforce this promise, agrees not to induce, directly or indirectly, any Grainger customer or supplier to breach any contract with Grainger, and further agrees not to solicit, attempt to hire, or hire, directly or indirectly, any Grainger employee, or request, induce or advise any such employee to leave the employment of Grainger at any time before the Termination Date and for one year thereafter. Should the Officer wish to hire a Grainger employee in contravention of this Section 9, or to perform work which is precluded by the Officer’s non-competition obligations set forth in Section 7 hereof, the Officer understands that he may request that Grainger agree that the Officer may perform such work or offer employment to such employee, and that with Grainger’s prior written agreement, which it may withhold at its sole discretion, the Officer may do so.

10. Return of Property: Business Expenses. The Officer shall promptly account for and return to Grainger all Grainger property, including but not limited to proprietary information, which is in the Officer’s possession or control. This property includes (but is not limited to) Officer’s Grainger work computer along with related drives and peripherals, correspondence, files, reports, minutes, plans, records, surveys, diagrams, computer print-outs, floppy disks, manuals, client/customer information and documentation, and any company research, goals, objectives, recommendations, proposals or other information relating to Grainger, its business, or its clients or customers, which is not generally known to the public, and which the Officer acquired in the course of his employment with Grainger. Notwithstanding, Officer shall be permitted to retain his Grainger cell phone along with his current telephone number. The Officer further agrees that all business expenses incurred prior to the Separation Date that are reimbursable in accordance with Grainger’s normal policies and procedures have been reimbursed to the Officer or submitted for reimbursement, and that other than as specifically provided in this Agreement, the Officer will not incur any additional business expenses after the Separation Date unless previously authorized and approved in writing by Grainger.

11. Confidential Information. The Officer agrees to refrain from ever disclosing to anyone outside the employment of Grainger any confidential or trade secret information, whether in oral, written and/or electronic form, including but not limited to information that (a) relates to Grainger’s or the Affiliates’ past, present and future research, development, technical and non-technical data and designs, finances, marketing, products, services, customers, suppliers, and other business activities of any kind or (b) has been identified, either orally or in writing, as confidential by Grainger or any Affiliate; provided that this limitation shall not apply to information that is part of the public domain through no breach of this Agreement or is acquired from a third party not under similar nondisclosure obligations to Grainger or such Affiliate. The Officer acknowledges that his obligations under any confidentiality or nondisclosure or similar agreements or provisions that the Officer previously executed will remain in full force and effect. Further, through the Termination Date, the Officer agrees to fully comply with all policies of Grainger regarding confidential or trade secret information.

12. Cooperation with Company. The Officer agrees, during the term of this Agreement as well as during the 12 month period immediately thereafter, to both make himself available and to provide reasonable cooperation to Grainger or its attorneys to assist Grainger or serve as a witness in connection with any matter, litigation or potential litigation in which the Officer may have knowledge, information, or expertise. The Officer also agrees to provide Grainger or its designated representatives, upon request, with information and assistance about programs, processes, and projects related to the Officer’s job responsibilities while employed by Grainger; to answer any questions relating to the work to which the Officer was assigned; and to otherwise provide reasonable cooperation to Grainger regarding matters relating to this Agreement and the Officer’s employment with Grainger. Grainger will reimburse the Officer for any reasonable expenses he incurs in activities which he undertakes at Grainger’s request pursuant to this Section 12.

13. Breach of Agreement; Misconduct. The Officer understands and agrees that if, after receiving all or any part of the payments and benefits described herein, the Officer breaches this Agreement, or commits or is discovered to have committed any act of embezzlement, fraud or theft with respect to the property of Grainger, or deliberately causes or is discovered to have deliberately caused, any loss, damage, injury or other endangerment to Grainger’s property, reputation or past, present, or future directors, officers or employees, Grainger reserves the right to demand repayment of all such payments and benefits. Grainger shall further be released from any future payment then or thereafter otherwise due and shall discontinue any and all benefit coverage (other than retiree health coverage, vested benefits under the PST and SPSP, and COBRA coverage if otherwise available). To the extent permitted by law, the Officer further understands and agrees that Grainger reserves the right to pursue all other available remedies in an effort to preserve its legitimate business interests. The Officer also agrees to indemnify and hold harmless Grainger from any loss, cost, damage, or expense, including attorneys’ fees, which Grainger may incur because of the Officer’s violation of this Agreement as determined by a Court of competent jurisdiction. Notwithstanding the above, nothing contained within this Agreement prevents either Party from pursuing a claim in either equity or law should there be a good faith belief that a breach of this Agreement has occurred. The Officer understands that this Section 13 does not apply to a challenge to the knowing and voluntary nature of this release with respect to claims under ADEA.

14. Supersedes Other Agreements. Other than any vested rights that the Officer may have under employee benefit plans subject to ERISA, the Officer understands that this Agreement supersedes any and all obligations (written or oral) which Grainger otherwise might have to the Officer for compensation or other expectations of remuneration or benefit on the Officer’s part. The Officer specifically acknowledges that all of Grainger’s obligations under the Change in Control Employment Agreement entered into between Grainger and the Officer (the “Change in Control Agreement”) shall become null and void as of the Resignation Date. Notwithstanding the above, all provisions contained within any Grainger Non-Competition Agreement, Stock Option, Special RSU, Option Grant or Performance Share Agreement entered into between the Officer and Grainger, or other Grainger Governance shall remain in full force and effect as originally executed and be incorporated by reference as being materials parts of this Agreement.

15. References. At the Officer’s request, Grainger will provide appropriate favorable references to prospective future employers of the Officer. Those references will be provided on behalf of Grainger by Jim Ryan or his designee on behalf of Grainger, with the specific content of such references to be mutually agreed between Grainger and the Officer in the future.

16. Continuation After Death. The Officer understands that in the event of the Officer’s death, Grainger’s obligations under this Agreement will extend to the Officer’s beneficiaries, heirs, executors, administrators, personal representatives and assigns.

17. Agreement Not Assignable. The Officer may not assign, and the Officer represents that he has not assigned, this Agreement or any rights or Grainger’s obligations under this Agreement to any other person.

18. Entire Understanding. The Officer understands and agrees that this Agreement, including Exhibit A hereto, contains the entire understanding between the parties and may not be amended except by mutual agreement in an amendment executed by both parties.

19. Severability. The provisions of this Agreement are declared to be severable, which means that if any provision of this Agreement or the application thereof is found to be invalid, the invalidity shall not affect other provisions or applications of this Agreement, which will be given effect without the invalid provisions or applications. In the event that a court of competent jurisdiction concludes that any term, provision or section of this Agreement is invalid or unenforceable (and, in the case of Section 7(a) of this Agreement, such provision is not modified by the court to be enforceable as described in Section 7(e) hereof), then said term, provision, or section shall be deemed eliminated from this Agreement to the extent necessary and in order to permit the remaining portions of the Agreement to be enforced. Any such eliminations shall not affect Grainger’s entitlement, if any, to receive, pursuant to Sections 7(e) and 13 hereof, amounts paid and benefits provided to the Officer under this Agreement.

20. Confidentiality of Agreement. The Officer represents and agrees to keep the terms, amount and fact of this Agreement completely confidential, and that the Officer will not disclose any information concerning this Agreement to anyone; provided, however, that this section will not prevent the Officer from disclosing information concerning this Agreement to the Officer’s attorneys, accountants, financial or tax advisors, spouse, a designated Grainger official, or as required by law. Notwithstanding, in accordance with U.S. Treasury Regulation 1.6011-4(b)(3)(iii), each party (and each employee, representative, or other agent of each party) to this Agreement may disclose to any and all persons, without limitation of any kind, the tax treatment, tax structure, and all materials of any kind provided to the other party relating to such tax treatment and tax structure.

21. Jurisdiction and Governing Law. The Officer acknowledges that for the purpose of this Agreement as well as his employment with Grainger, he is an Illinois employee. This Agreement shall in all respects be interpreted, enforced and governed by and under the laws of the State of Illinois, without regard to its conflicts of law principles.

22. Voluntary Agreement. The Officer acknowledges that the payments and benefits that Grainger is providing hereunder exceed the compensation and benefits otherwise payable to the Officer or on the Officer’s behalf and that such Separation Payments and benefits are provided by Grainger in exchange for execution of this Agreement. The Officer acknowledges that he was given twenty-one (21) days to consider the terms of this Agreement, that the Officer may revoke this Agreement at any time within seven (7) days after the date that the Officer signs it, and that he has been advised to and has had the opportunity to seek out counsel of his own choice. Any revocation must be communicated in writing, via personal delivery or overnight mail, to Henry F. Galatz, Labor Counsel, W.W. Grainger, Inc., 100 Grainger Parkway, Lake Forest, Illinois 60045. The Officer further understands that this Agreement does not take effect until after the expiration of the seven (7) day period for revocation. All referenced Separation Payments and applicable benefits identified in this Agreement will automatically cease on the 21^st day should the Officer not return a fully executed copy of this Agreement to Grainger within the specified 21-day consideration period. The Officer has read this Agreement and understands all of its terms.

I have read this Separation Agreement and General Release and I understand all of its terms. I voluntarily execute this Separation Agreement and General Release with full knowledge of its meaning, on this 4^th day of October 2013.

SUMMARY DESCRIPTION OF THE

COMPANY MANAGEMENT INCENTIVE PROGRAM

I. Introduction

The Company Management Incentive Program (MIP) is designed to focus on two key factors that drive improvements in shareholder value:  return on invested capital (ROIC) and sales growth.

II. Objectives

The MIP is designed to:

• Encourage decision-making focused on producing a favorable rate of ROIC and on growing the business rapidly, thus leading to improvements in shareholder value.

• Influence participants to make decisions consistent with shareholders’ interests.

• Align management with Company objectives.

• Attract and retain the talent required to achieve the Company’s objectives.

III. Eligibility

Positions that participate in this program are those that have significant impact on the Company. Eligibility for participation in this program is based on the determination of management. Criteria for inclusion are market practice, impact of the role on overall Company results, and internal practice. Participation in this program is subject to the Terms and Conditions.

IV. Performance Measures

Shareholder value will improve most dramatically if the Company can achieve two goals simultaneously:

1. Produce a constantly improving rate of ROIC, and

2. Grow the business rapidly.

The MIP will be based on ROIC and sales growth. The payout earned is the sum of the ROIC and sales growth results. This can be represented algebraically as follows:

Total Payout = ROIC Payout + Sales Growth Payout

ROIC is defined as operating earnings divided by net working assets:

ROIC = Operating Earnings Net Working Assets

The ROIC component will range from 0% to 60% of a participant’s total Target Incentive.

Sales growth is defined as year-over-year performance:

Sales growth = Total Company Sales, Current Year   Total Company Sales, Prior Year -1

The sales growth component will range from 0% to 150% of a participant’s total Target Incentive.

The overall incentive amount earned is capped at 200% of a participant's total Target Incentive. 

Management would be allowed to recommend discretionary adjustments to the ROIC and sales growth portions of the payout, to correct for any windfalls or shortfalls beyond the control of participants.

V. Target Award Opportunity

Target awards for each position are based on competitive market practice and internal considerations and are stated as a percentage of the employee’s base salary.

VI. Determination Of Payment Amounts

The following process is used to determine the payment amount for each participant.

Step 1: Determine the performance results for ROIC and the resultant performance to goal. Compute the appropriate percentage of Target Incentive earned.

Step 2: Determine the performance results for sales growth and the resultant performance to goal. Compute the appropriate percentage of Target Incentive earned.  Add these results to the results from Step 1 to determine the Total % Payout.

Step 3: Calculate each participant’s incentive amount earned as follows:

Incentive Amount Earned = Total % Payout x (Annualized Base Salary (as of 12/31)  x  Target Incentive %)

Those employees who are eligible to participate for only part of the year will have their incentive amount adjusted accordingly, based on the eligibility provisions of the Terms and Conditions.

Step 4: The Compensation Committee of Management and the Compensation Committee of the Board must approve final incentive amounts.

Step 5: Once approved, final incentive amounts are forwarded to the Employee Systems manager for payment.

Notes to Financial Statements [Abstract]

SEGMENT INFORMATION

SEGMENT INFORMATION

The Company has two reportable segments:  the United States and Canada.  The United States operating segment reflects the results of the Company’s U.S. business.  The Canada operating segment reflects the results for Acklands – Grainger Inc., the Company’s Canadian business.  Other businesses include the Company's operations in Europe, Asia, Latin America and other U.S. operations. These businesses individually do not meet the criteria of a reportable segment. Operating segments generate revenue almost exclusively through the distribution of maintenance, repair and operating supplies, as service revenues account for less than 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.

Following is a summary of segment results (in thousands of dollars):

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

12 Months Ended

Dec. 31, 2013

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]

PRINCIPLES OF CONSOLIDATION

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany transactions are eliminated from the consolidated financial statements.

EQUITY METHOD OF ACCOUNTING FOR INVESTMENTS

EQUITY METHOD OF ACCOUNTING FOR INVESTMENTS

For investments in which the Company owns or controls from 20% to 50% of the voting shares, the equity method of accounting is used. The Company also accounts for investments below 20% using the equity method when significant influence can be exercised over the operating and financial policies of the investee company.

In October 2011, the Company divested its 49% stake in a joint venture, MRO Korea Co., Ltd., for $12 million, resulting in a pretax gain of $8 million ($5 million after-tax) net of the cumulative foreign currency losses reclassified from Accumulated other comprehensive earnings. The Company previously accounted for this investment under the equity method.

USE OF ESTIMATES

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

FOREIGN CURRENCY TRANSLATION

The financial statements of the Company's foreign subsidiaries are measured using the local currency as the functional currency. Net exchange gains or losses resulting from the translation of financial statements of foreign operations and related long-term debt and derivative instruments are recorded as a separate component of other comprehensive earnings. See Note 13 to the Consolidated Financial Statements.

RECLASSIFICATIONS

RECLASSIFICATIONS

Certain amounts in the 2012 and 2011 financial statements, as previously reported, have been reclassified to conform to the 2013 presentation.

REVENUE RECOGNITION

REVENUE RECOGNITION

Revenues recognized include product sales, billings for freight and handling charges and fees earned for services provided. The Company recognizes product sales and billings for freight and handling charges primarily on the date products are shipped to, or picked up by, the customer. In cases where the product is shipped directly to the customer, the company recognizes revenue at the time of shipment on a gross basis. The Company's standard shipping terms are FOB shipping point. On occasion, the Company will negotiate FOB destination terms. These sales are recognized upon delivery to the customer. eCommerce revenues, which accounted for 33% of total 2013 revenues, are recognized on the same terms as revenues through other channels. Fee revenues, which accounted for less than 1% of total 2013 revenues, are recognized after services are completed. Taxes collected from customers and remitted to governmental authorities are presented on a net basis and are not included in revenue.

COST OF MERCHANDISE SOLD

COST OF MERCHANDISE SOLD

Cost of merchandise sold includes product and product-related costs, vendor consideration, freight-out and handling costs. The Company defines handling costs as those costs incurred to fulfill a shipped sales order.

VENDOR CONSIDERATION

VENDOR CONSIDERATION

The Company receives rebates and allowances from its vendors to promote their products. The Company utilizes numerous advertising programs to promote its vendors' products, including catalogs and other printed media, Internet, radio and other marketing programs. Most of these programs relate to multiple vendors, which makes supporting the specific, identifiable and incremental criteria difficult, and would require numerous assumptions and judgments. Based on the inexact nature of trying to track reimbursements to the advertising expenditure for each vendor, the Company treats most vendor advertising allowances as a reduction to Cost of merchandise sold rather than a reduction of operating (advertising) expenses. 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 Cost of merchandise sold based on sales. Vendor rebates that are earned based on products sold are credited directly to Cost of merchandise sold.

ADVERTISING

ADVERTISING

Advertising costs are expensed in the year the related advertisement is first presented. Advertising expense was $178 million, $173 million and $145 million for 2013, 2012 and 2011, respectively. Most vendor-provided allowances are classified as an offset to Cost of merchandise sold. For additional information see VENDOR CONSIDERATION above.

Catalog expense is amortized equally over the life of the catalog, beginning in the month of its distribution. Advertising costs for catalogs that have not been distributed by year-end are capitalized as Prepaid expenses. Amounts included in Prepaid expenses at December 31, 2013 and 2012, were $36 million and $46 million, respectively.

WAREHOUSING, MARKETING AND ADMINISTRATIVE EXPENSES

WAREHOUSING, MARKETING AND ADMINISTRATIVE EXPENSES

Included in this category are purchasing, branch operations, information services, and marketing and selling expenses, as well as other types of general and administrative costs.

STOCK INCENTIVE PLANS

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. See Note 11 to the Consolidated Financial Statements.

INCOME TAXES

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. See Note 14 to the Consolidated Financial Statements.

OTHER COMPREHENSIVE EARNINGS (LOSSES)

OTHER COMPREHENSIVE EARNINGS (LOSSES)

The Company's Other comprehensive earnings (losses) include foreign currency translation adjustments, changes in fair value of derivatives designated as hedges and unrecognized gains (losses) on postretirement and other employment-related benefit plans. See Note 13 to the Consolidated Financial Statements.

CASH AND CASH EQUIVALENTS

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.

CONCENTRATION OF CREDIT RISK

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 all regions of the United States, Canada, Europe, Asia and Latin America. Consequently, no significant concentration of credit risk is considered to exist.

ALLOWANCE FOR DOUBTFUL ACCOUNTS

ALLOWANCE FOR DOUBTFUL ACCOUNTS

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.

INVENTORIES

INVENTORIES

Inventories are valued at the lower of cost or market. Cost is determined primarily by the last-in, first-out (LIFO) method, which accounts for approximately 59% of total inventory. For the remaining inventory, cost is determined by the first-in, first-out (FIFO) method.

PROPERTY, BUILDINGS AND EQUIPMENT

PROPERTY, BUILDINGS AND EQUIPMENT

Property, buildings and equipment are valued at cost. For financial statement purposes, depreciation and amortization are provided 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	10 to 30 years
Furniture, fixtures, machinery and equipment	3 to 10 years

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 $1 million in each of years 2013, 2012 and 2011.

LONG-LIVED ASSETS

LONG-LIVED ASSETS

The carrying value of long-lived assets 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 carrying amount exceeds the fair value.

The Company recognized impairment charges of $0.4 million, $2 million and $8 million in 2013, 2012 and 2011, respectively, included in Warehousing, marketing and administrative expenses, to reduce the carrying value of certain long-lived assets to their estimated fair value pursuant to impairment indicators for property currently held for sale, lease terminations, idle assets and branch closures.

CAPITALIZED SOFTWARE

CAPITALIZED SOFTWARE

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 and five years. Amortization begins when the software is available for its intended use. Amortization expense was $23 million, $16 million and $19 million for the years ended December 31, 2013, 2012 and 2011, respectively. Capitalized software was $107 million and $72 million at December 31, 2013 and 2012, respectively and are included in Other assets and intangibles - net on the Consolidated Balance Sheets.

GOODWILL AND OTHER INTANGIBLES

GOODWILL AND OTHER INTANGIBLES

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 implied fair value of goodwill is less than its carrying value.

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 unless the estimated useful life is determined to be indefinite. Amortizable intangible assets are being amortized primarily over useful lives of three to 22 years. The straight-line method of amortization is used as it has been determined to approximate customer attrition patterns and the use pattern of the assets. Impairment losses are recognized if the carrying amount of an intangible, subject to amortization, is not recoverable from expected future cash flows and its carrying amount exceeds its fair value.

The Company also maintains intangible assets with indefinite lives, which are not amortized. These intangibles are tested for impairment on an annual basis and more often if circumstances require. Impairment losses are recognized whenever the implied fair value of these assets is less than their carrying value. See Note 2 and Note 3 to the Consolidated Financial Statements.

FAIR VALUE OF FINANCIAL INSTRUMENTS

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. The carrying value of long-term debt also approximates fair value due to the variable interest rates. The fair value of the Company's qualifying derivative instruments is recorded in the Consolidated Balance Sheets and is discussed in more detail in Note 8 to the Consolidated Financial Statements.

DERIVATIVE INSTRUMENTS AND HEDGING

DERIVATIVE INSTRUMENTS AND HEDGING

The Company uses derivative financial instruments to manage exposures to fluctuations in interest rates and foreign currency exchange rates. The Company does not enter into derivative financial instruments for trading or speculative purposes. All derivative instruments are recognized as either assets or liabilities in the balance sheet at their fair value. Changes in the fair value of derivatives are recognized in net earnings or other comprehensive earnings (losses) depending on whether the derivative is designated as part of a qualifying hedging relationship. The ineffective portion of a qualifying hedging derivative and derivatives not designated as a hedge are recognized immediately in earnings. Instruments that do not qualify for hedge accounting are marked to market with the change recognized in current period earnings. See Note 8 and Note 13 to the Consolidated Financial Statements for additional information on the Company's derivative activities.

INSURANCE RESERVES

INSURANCE RESERVES

The Company purchases insurance for catastrophic exposures and those risks required to be insured by law. It also retains a significant portion of the risk of certain losses related to workers' compensation, general liability and property losses through the utilization of high deductibles and self-insured retentions. Reserves for these potential losses are based on an external analysis of the Company's historical claims results and other actuarial assumptions.

WARRANTY RESERVES

WARRANTY RESERVES

The Company generally warrants the products it sells against defects for one year. For a significant portion of warranty claims, the manufacturer of the product is responsible for expenses. For warranty expenses not covered by the manufacturer, the Company provides a reserve for future costs based primarily on historical experience. Warranty reserves were $4 million at December 31, 2013 and 2012

NEW ACCOUNTING STANDARDS

NEW ACCOUNTING STANDARDS

In February 2013, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. Under ASU 2013-02, an entity is required to provide information about the amounts reclassified out of accumulated other comprehensive income (AOCI) by component. In addition, an entity is required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of AOCI by the respective line items of net income, but only if the amount reclassified is required to be reclassified in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide details about those amounts. ASU 2013-02 does not change the current requirements for reporting net income or other comprehensive income in the financial statements. ASU 2013-02 is effective for interim and annual periods beginning after December 15, 2012 and early adoption is permitted. The Company adopted ASU 2013-02 in the first quarter of 2013. The adoption of ASU 2013-02 did not have a material impact on the consolidated financial statements.

In July 2013, the Financial Accounting Standards Board issued ASU 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. The guidance requires the presentation of certain unrecognized tax benefits as reductions to deferred tax assets rather than as liabilities in the condensed consolidated balance sheets when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The amendments will be effective for interim and annual periods beginning after December 15, 2013. Early adoption and retrospective application are permitted. The Company does not expect the adoption of ASU 2013-11 to have a material impact on the Company’s consolidated financial statements.

EARNINGS PER SHARE

EARNINGS PER SHARE

The Company’s unvested Restricted Stock Units and Directors' Deferred Stock Units 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 is 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 thousands of dollars, except for share and per share amounts):

DERIVATIVE INSTRUMENTS

DERIVATIVE INSTRUMENTS

The fair values of the Company's derivative instruments are determined by using quoted market forward rates (Level 2 inputs) and reflect the present value of the amount that the Company would pay for contracts involving the same notional amounts and maturity dates.

During the fourth quarter of 2011, the Company entered into a pay-fixed / receive floating interest rate swap with a notional value of €60 million maturing in August 2016 to partially hedge the future interest expense of the euro-denominated term loan entered into to fund a portion of the Fabory acquisition. The swap is accounted for as a cash flow hedge. The effective portion of the changes in fair value of the derivative is reported as a component of other comprehensive earnings (losses) and reclassified to net income when the hedged transaction affects earnings. The value of the interest-rate swap, included on the Company's balance sheet under Employment-related and other noncurrent liabilities, was $3 million and $4 million as of December 31, 2013 and 2012, respectively.

During the fourth quarter of 2010, the Company entered into multiple foreign currency forward contracts with a total notional value of C$160 million maturing in September 2014. These forward contracts are designated and qualify as a hedge of an intercompany net investment in the Company's Canadian subsidiary. The Company uses the forward method of assessing hedge effectiveness for derivatives designated as hedging instruments of a net investment in a foreign subsidiary and all changes in fair value of the derivatives are reported as a component of other comprehensive earnings (losses), net of tax effects, as long as specific hedge accounting criteria are met. As of December 31, 2013, the foreign currency forward contracts were included on the Company's balance sheet under Prepaid expenses and other assets for $1 million. As of December 31, 2012, the foreign currency forward contracts were included on the Company's balance sheet under Employment-related and other noncurrent liabilities for $8 million.

Other foreign currency forward contracts entered into during the current and prior periods to hedge non-functional currency-denominated intercompany note receivables and forecasted U.S. dollar-denominated obligations by foreign subsidiaries of the Company were not material.

See Note 1 to the Consolidated Financial Statements for a description of the Company's Accounting Policy regarding derivative instruments and Note 13 to the Consolidated Financial Statements for additional information.

EMPLOYEE BENEFITS

12 Months Ended

Dec. 31, 2013

Notes to Financial Statements [Abstract]

EMPLOYEE BENEFITS

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. This plan provides for annual employer contributions based upon a formula related primarily to earnings before federal income taxes, limited to a percentage of the total eligible compensation paid to eligible employees. The annual contribution is limited to a minimum of 8% and a maximum of 18% of total eligible compensation paid to eligible employees. The profit sharing plan expense was $173 million, $165 million and $156 million for 2013, 2012 and 2011, respectively.

The Company sponsors additional defined contribution plans available to certain U.S. and foreign employees for which contributions are paid by the Company and participating employees. The expense associated with these defined contribution plans totaled $12 million for each of the years ended December 31, 2013 and 2012 and $9 million for 2011.

Defined Benefit Plans and Other Retirement Plans

The Company sponsors a defined benefit plan which provides pension benefits for certain employees in the Netherlands. The annual pension benefit is based on 1.75 percent of a career average pay and years of service. The plan is insured and accordingly, all risks with respect to investments, mortality and longevity are covered by an insurance company. The assets of the plan are invested in a separate account with the insurer. A December 31 measurement date is utilized to value plan assets and obligations. Funding of the plan takes place through single premiums for obligations regarding future service years. As of December 31, 2013 and 2012, the pension plan was in an overfunded position with a net pension asset of $5 million and $6 million, respectively. The expense related to this plan was not significant to the Company in the past three years.

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. The cost of these programs is not significant to the Company.

Executive Death Benefit Plan

The Executive Death Benefit Plan provides one of three potential benefits: a supplemental income benefit (SIB), an executive death benefit (EDB) or a postretirement payment. The SIB provides income continuation at 50% of total compensation, payable for ten years to the beneficiary of a participant if that participant dies while employed by the Company. The EDB provides an after-tax lump sum payment of one-time final total compensation to the beneficiary of a participant who dies after retirement. In addition, pre-2008 participants may elect to receive a reduced postretirement payment instead of the EDB. Effective January 1, 2010, the plan is not available to new participants.

The net periodic benefits costs charged to operating expenses were $0.8 million in year 2013 and $1 million in 2012 and 2011. The net loss (gain) recognized in Accumulated other comprehensive earnings (AOCE) was $(1) million and $0.2 million as of December 31, 2013, and 2012, respectively. The plan benefits are paid as they come due from the general assets of the Company. The plan benefit obligation was $15 million as of December 31, 2013, and $17 million as of December 31, 2012.

Postretirement Benefits

The Company has a postretirement healthcare benefits plan that provides coverage for a majority of its United States 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 fourth quarter 2012, the Company implemented plan design changes effective January 1, 2013. Employees hired after January 1, 2013 are not eligible to receive retiree health benefits. Active participants in the plan as of December 31, 2012 will remain eligible for retiree health benefits with the employee contribution structure modified for certain employees based on retirement eligibility. As a result of this plan amendment, the Company's postretirement benefit obligation declined $84 million as of December 31, 2012.

During the fourth quarter 2012, the Company also implemented an Employer Group Waiver Plan (EGWP) and a secondary supplemental "wrap-around" plan for its Medicare eligible retiree medical plan participants and no longer applied for the Part D Retiree Drug Subsidy (RDS) effective January 1, 2013. The EGWP program does not alter the benefits expected to be provided to the plan participants and is expected to increase the level of Medicare subsidies that will offset plan costs. Accordingly, the event was recognized as an actuarial gain for the year ended December 31, 2012. As a result of this change, the Company's postretirement benefit obligation declined $19 million as of December 31, 2012.

The “Medicare Prescription Drug, Improvement and Modernization Act of 2003” provides a federal subsidy to retiree healthcare benefit plan sponsors that provide a prescription drug benefit that is at least actuarially equivalent to that provided by Medicare. As a result of the subsidy, the Company's postretirement benefit obligation reflected a reduction of $68 million as of December 31, 2011. As a result of the implementation of the EGWP program, the benefit obligation was no longer reduced by Part D RDS as of December 31, 2012. The subsidy reduced net periodic benefits costs by approximately $9 million and $7 million for the years ended December 31, 2012 and 2011, respectively.

The net periodic benefits costs charged to operating expenses, which were valued with a measurement date of January 1 for each year, consisted of the following components (in thousands of dollars):

	For the Years Ended December 31,
	2013			2012			2011
Service cost	$	10,589		$	20,058		$	15,762

Amortization of unrecognized losses	3,724			4,827			3,269
Net periodic benefits costs	$	8,620		$	30,847		$	25,955

The Company has elected to amortize the amount of net unrecognized gains (losses) over a period equal to the average remaining service period for active plan participants expected to retire and receive benefits of approximately 15.6 years for 2013.

Reconciliations of the beginning and ending balances of the postretirement benefit obligation, which is calculated using a December 31 measurement date, the fair value of plan assets and the funded status of the benefit obligation follow (in thousands of dollars):

The components of AOCE related to the postretirement benefit costs that will be amortized into net periodic postretirement benefit costs in 2014 are estimated as follows (in thousands of dollars):

	2014
Amortization of prior service credit	$	(7,253	)
Amortization of transition asset	(143		)
Amortization of unrecognized losses	1,154
Estimated amount to be amortized from AOCE into net periodic postretirement benefit costs	$	(6,242	)

The benefit obligation was determined by applying the terms of the plan and actuarial models. These models include various actuarial assumptions, including discount rates, assumed 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 following assumptions were used to determine net periodic benefit costs at January 1:

	For the Years Ended December 31,
	2013		2012		2011
Discount rate	4.00	%	4.50	%	5.60	%
Expected long-term rate of return on plan assets, net of tax	6.00	%	6.00	%	6.00	%
Initial healthcare cost trend rate	8.00	%	8.50	%	9.00	%
Ultimate healthcare cost trend rate	5.00	%	5.00	%	5.00	%
Year ultimate healthcare cost trend rate reached	2019		2019		2019

The following assumptions were used to determine benefit obligations at December 31:

	2013		2012		2011
Discount rate	4.90	%	4.00	%	4.50	%
Expected long-term rate of return on plan assets, net of tax	5.70	%	6.00	%	6.00	%
Initial healthcare cost trend rate	7.50	%	8.00	%	8.50	%
Ultimate healthcare cost trend rate	4.50	%	5.00	%	5.00	%
Year ultimate healthcare cost trend rate reached	2026		2019		2019

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, 2013, the Company increased the discount rate from 4.0% to 4.9% to reflect the increase in the market interest rates which contributed to the decrease in the unrealized actuarial loss at December 31, 2013. The Company reviews external data and its own historical trends for healthcare costs to determine the healthcare cost trend rates. Grainger changed the duration of the healthcare trend rate to an assumed rate of increase of 7.5% declining 25 basis points a year until reaching the ultimate trend rate of 4.5% from an assumed rate of increase declining 50 basis points a year. This has the effect of moving the year that the ultimate trend rate is reached to 2026. Assumed healthcare cost trend rates have a significant effect on the amounts reported for the healthcare plans. A 1 percentage point change in assumed healthcare cost trend rates would have the following effects on 2013 results (in thousands of dollars):

	1 Percentage Point
	Increase		(Decrease)
Effect on total service and interest cost	$	2,205	$	(1,777	)
Effect on postretirement benefit obligation	29,776		(24,196		)

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 the net asset value of shares held by the plan in the registered investment companies at the quoted market prices (Level 1 input) as of December31 (in thousands of dollars):

	2013		2012
Registered investment companies
Fidelity Spartan U.S. Equity Index Fund	$	67,160	$	51,169
Vanguard 500 Index Fund	67,931		51,336
Vanguard Total International Stock	25,034		21,739
Total Assets	$	160,125	$	124,244

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. In 2013, Grainger decreased the expected long-term rate of return on plan assets from 6.0% (net of tax) to 5.7% (net of tax) based on the historical average of long-term rates of return. The required use of an expected long-term rate of return on plan assets may result in recognition of income that is greater or less 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 (which include a projection for expected future employee service) for the next ten years (in thousands of dollars):

Year	Estimated Gross Benefit Payments
2014	$	5,299
2015	6,075
2016	6,952

GOODWILL AND OTHER INTANGIBLE ASSETS

GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill is recognized as the excess cost of an acquired entity over the 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 implied fair value of goodwill is less than its carrying value.

The changes in the carrying amount of goodwill by segment are as follows (in thousands of dollars):

	United States			Canada			Other Businesses			Total

Business acquisitions result in the recording of goodwill and identified intangible assets which affect the amount of amortization expense and possible impairment write-downs that may occur in future periods. Grainger annually reviews goodwill and intangible assets with indefinite lives for impairment in the fourth quarter and when events or changes in circumstances indicate the carrying value of these assets might exceed their current fair values. Grainger tests for goodwill impairment at the reporting unit level and performs a qualitative assessment of factors such as a reporting unit's current performance and overall economic factors to determine if it is more likely than not that the goodwill might be impaired and whether it is necessary to perform the two-step quantitative goodwill impairment test. In the two-step test, Grainger compares the carrying value of assets of the reporting unit to its calculated fair value. If the carrying value of assets of the reporting unit exceeds its calculated fair value, the second step is performed, where the implied fair value of goodwill is compared to the carrying value of assets, to determine the amount of impairment.

The fair value of reporting units is calculated using primarily the discounted cash flow (DCF) method and incorporating value indicators from a market approach to evaluate the reasonableness of the resulting fair values. The DCF method incorporates various assumptions including the amount and timing of future expected cash flows, including revenues, gross margins, operating expenses, capital expenditures and working capital based on operational budgets, long range strategic plans and other estimates. The terminal value growth rate is used to calculate the value of cash flows beyond the last projected period and reflects management’s best estimates for perpetual growth for the reporting units. Estimates of market-participant risk-adjusted weighted average cost of capital (WACC) are used as a basis for determining the discount rates to apply to the reporting units’ future expected cash flows and terminal value.

Grainger completed the annual impairment testing using the qualitative approach for seven reporting units and the two-step quantitative test for four of these reporting units during the fourth quarter. For two of these reporting units, Grainger Lighting Services (GLS) and Grainger Brazil (GB), the two-step quantitative test indicated that the carrying value of assets exceeded the calculated fair value and step two impairment calculations were required. As part of the review of the strategic plans for GLS during the fourth quarter, Grainger evaluated the impact of planned changes to the business model and level of investment in the business. Grainger’s estimates of future projected sales growth, operating earnings, and cash flows were revised to reflect lower estimates for new customers and projects.  As a result of the lower projections, Grainger recognized impairment charges of $13 million on the GLS reporting unit.

During the fourth quarter, management provided strategic plans which included changes to the business model and level of investment required for GB based on insights gained from owning the business since the acquisition in the second quarter of 2012. Grainger’s assumptions were revised to reflect changes related to realization of expected deal synergies and anticipated short-term and long-term operating results of GB that were different from pre-acquisition projections. As a result of the lower performance expectations, Grainger’s estimates for future projected sales growth, operating earnings, and cash flows were revised accordingly. These lowered expectations, as well as an increase in relevant risk factors that increased the discount rate used in the calculations, resulted in the calculated fair value of GB being lower than the carrying value of assets in the step one analysis.  As a result of the completion of step two, Grainger recognized a goodwill impairment charge of $11 million.

For the two other reporting units, the fair values calculated in the step one analysis exceeded the carrying value of assets and therefore the step two calculation was not required. Fabory, with $134 million of goodwill, had a calculated fair value which exceeded the carrying value of assets by 17%. The risk of potential failure of step one of the impairment test for Fabory in future reporting periods is highly dependent upon key assumptions including the amount and timing of future expected cash flows, sales growth rates, gross margins, capital expenditures, discount rates and estimates of market-participant risk-adjusted WACC. These assumptions require considerable management judgment and are subject to uncertainty. Changes in assumptions regarding the future performance and a continued unfavorable economic environment in Europe may also have a significant impact on cash flows in the future. Given the sensitivity of the calculated fair value to changes in these key assumptions, Grainger may be required to recognize an impairment for Fabory’s goodwill in the future due to changes in market conditions or other factors related to these key assumptions.

Grainger Colombia, with $14 million of goodwill, had a calculated fair value which exceeded the carrying value of assets by 26% as of the test date.

INCOME TAXES

INCOME TAXES

The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities, using enacted tax rates in effect for the year in which the differences are expected to reverse.

Income tax expense consisted of the following (in thousands of dollars):

	For the Years Ended December 31,
	2013			2012		2011
Current provision:

Net deferred tax asset	$	23,597		$	32,066

At December 31, 2013, the Company had $262 million of operating loss carryforwards related primarily to foreign operations. Some of the operating loss carryforwards may expire at various dates through 2023. The Company has recorded a valuation allowance, which represents a provision for uncertainty as to the realization of the tax benefits of these carryforwards. In addition, the Company recorded a valuation allowance to reflect the estimated amount of deferred tax assets that may not be realized.

The changes in the valuation allowance were as follows (in thousands of dollars):

	For the Years Ended December 31,
	2013		2012
Beginning balance	$	54,434	$	53,739
Increase related to foreign net operating loss carryforwards	8,391		695

A reconciliation of income tax expense with federal income taxes at the statutory rate follows (in thousands of dollars):

	For the Years Ended December 31,
	2013			2012			2011
Federal income tax at the 35% statutory rate	$	450,660		$	391,226		$	368,034

Effective tax rate	37.3		%	37.5		%	36.6		%

In 2011, other - net included the tax benefit related to settlement of various tax reviews during 2011 and the benefit of tax law changes in Japan enacted in the fourth quarter of 2011.

Undistributed earnings of foreign subsidiaries at December 31, 2013, amounted to $386 million. No provision for deferred U.S. income taxes has been made for these subsidiaries because the Company intends to permanently reinvest such earnings in its foreign operations. If at some future date these earnings cease to be permanently invested, the Company may be subject to U.S. income taxes, foreign withholding, and other taxes on such amounts, which cannot be reasonably estimated at this time.

The changes in the liability for tax uncertainties, excluding interest, are as follows (in thousands of dollars):

	2013			2012
Balance at beginning of year	$	40,937		$	22,760
Additions to tax positions related to the current year	8,396			11,369
Additions for tax positions of prior years	2,308			8,977
Reductions for tax positions of prior years	(7,242		)	(1,447		)
Reductions due to statute lapse	(18		)	(737		)
Settlements, audit payments, refunds - net	(4,064		)	15
Balance at end of year	$	40,317		$	40,937

The Company classifies the liability for tax uncertainties in Deferred income taxes and tax uncertainties. Included in this amount are $8 million and $6 million at December 31, 2013 and 2012, 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. The reduction to tax positions of prior years in 2013 related primarily to law changes, conclusion of audits and audit settlements.

The Company regularly undergoes examination of its federal income tax returns by the Internal Revenue Service (IRS). The Company's federal tax returns for 2009 and 2010 are currently under audit by the IRS, and the tax years 2011 through 2013 are open. The Company is also subject to audit by state, local and foreign taxing authorities. Tax years 2002 - 2013 remain subject to state and local audits and 2006 - 2013 remain subject to foreign audits. The estimated amount of liability associated with the Company's uncertain tax positions 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 in the provision for income taxes. During 2013 and 2012, the Company recognized an expense of $2 million and $1 million, respectively. During 2011, the Company recognized a net benefit of $1 million, primarily due to settlement of audits and a statute lapse. As of December 31, 2013 and 2012, the Company accrued approximately $4 million and $2 million, respectively, for interest.

The Company leases certain land, buildings and equipment under noncancellable operating leases that expire at various dates through 2036. Capital leases as of December 31, 2013 are not considered material. 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.

At December 31, 2013, the approximate future minimum lease payments for all operating leases were as follows (in thousands of dollars):

Year	Future Minimum Lease Payments
2014	$	67,993

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

INDUSTRY INFORMATION

W.W. Grainger, Inc. is a broad-line distributor of maintenance, repair and operating supplies, and other related products and services used by businesses and institutions. 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. All significant intercompany transactions are eliminated from the consolidated financial statements.

EQUITY METHOD OF ACCOUNTING FOR INVESTMENTS

For investments in which the Company owns or controls from 20% to 50% of the voting shares, the equity method of accounting is used. The Company also accounts for investments below 20% using the equity method when significant influence can be exercised over the operating and financial policies of the investee company.

In October 2011, the Company divested its 49% stake in a joint venture, MRO Korea Co., Ltd., for $12 million, resulting in a pretax gain of $8 million ($5 million after-tax) net of the cumulative foreign currency losses reclassified from Accumulated other comprehensive earnings. The Company previously accounted for this investment under the equity method.

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 financial statements of the Company's foreign subsidiaries are measured using the local currency as the functional currency. Net exchange gains or losses resulting from the translation of financial statements of foreign operations and related long-term debt and derivative instruments are recorded as a separate component of other comprehensive earnings. See Note 13 to the Consolidated Financial Statements.

RECLASSIFICATIONS

Certain amounts in the 2012 and 2011 financial statements, as previously reported, have been reclassified to conform to the 2013 presentation. These reclassifications did not have a material impact on the presentation of the consolidated financial statements.

REVENUE RECOGNITION

Revenues recognized include product sales, billings for freight and handling charges and fees earned for services provided. The Company recognizes product sales and billings for freight and handling charges primarily on the date products are shipped to, or picked up by, the customer. In cases where the product is shipped directly to the customer, the company recognizes revenue at the time of shipment on a gross basis. The Company's standard shipping terms are FOB shipping point. On occasion, the Company will negotiate FOB destination terms. These sales are recognized upon delivery to the customer. eCommerce revenues, which accounted for 33% of total 2013 revenues, are recognized on the same terms as revenues through other channels. Fee revenues, which accounted for less than 1% of total 2013 revenues, are recognized after services are completed. Taxes collected from customers and remitted to governmental authorities are presented on a net basis and are not included in revenue.

COST OF MERCHANDISE SOLD

Cost of merchandise sold includes product and product-related costs, vendor consideration, freight-out and handling costs. The Company defines handling costs as those costs incurred to fulfill a shipped sales order.

VENDOR CONSIDERATION

The Company receives rebates and allowances from its vendors to promote their products. The Company utilizes numerous advertising programs to promote its vendors' products, including catalogs and other printed media, Internet, radio and other marketing programs. Most of these programs relate to multiple vendors, which makes supporting the specific, identifiable and incremental criteria difficult, and would require numerous assumptions and judgments. Based on the inexact nature of trying to track reimbursements to the advertising expenditure for each vendor, the Company treats most vendor advertising allowances as a reduction to Cost of merchandise sold rather than a reduction of operating (advertising) expenses. 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 Cost of merchandise sold based on sales. Vendor rebates that are earned based on products sold are credited directly to Cost of merchandise sold.

ADVERTISING

Advertising costs are expensed in the year the related advertisement is first presented. Advertising expense was $178 million, $173 million and $145 million for 2013, 2012 and 2011, respectively. Most vendor-provided allowances are classified as an offset to Cost of merchandise sold. For additional information see VENDOR CONSIDERATION above.

Catalog expense is amortized equally over the life of the catalog, beginning in the month of its distribution. Advertising costs for catalogs that have not been distributed by year-end are capitalized as Prepaid expenses. Amounts included in Prepaid expenses at December 31, 2013 and 2012, were $36 million and $46 million, respectively.

WAREHOUSING, MARKETING AND ADMINISTRATIVE EXPENSES

Included in this category are purchasing, 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. See Note 11 to the Consolidated 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. See Note 14 to the Consolidated Financial Statements.

OTHER COMPREHENSIVE EARNINGS (LOSSES)

The Company's Other comprehensive earnings (losses) include foreign currency translation adjustments, changes in fair value of derivatives designated as hedges and unrecognized gains (losses) on postretirement and other employment-related benefit plans. See Note 13 to the Consolidated 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.

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 all regions of the United States, Canada, Europe, Asia and Latin America. Consequently, no significant concentration of credit risk is considered to exist.

ALLOWANCE FOR DOUBTFUL ACCOUNTS

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.

INVENTORIES

Inventories are valued at the lower of cost or market. Cost is determined primarily by the last-in, first-out (LIFO) method, which accounts for approximately 59% of total inventory. For the remaining inventory, cost is determined by the first-in, first-out (FIFO) method.

PROPERTY, BUILDINGS AND EQUIPMENT

Property, buildings and equipment are valued at cost. For financial statement purposes, depreciation and amortization are provided 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	10 to 30 years
Furniture, fixtures, machinery and equipment	3 to 10 years

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 $1 million in each of years 2013, 2012 and 2011.

LONG-LIVED ASSETS

The carrying value of long-lived assets 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 carrying amount exceeds the fair value.

The Company recognized impairment charges of $0.4 million, $2 million and $8 million in 2013, 2012 and 2011, respectively, included in Warehousing, marketing and administrative expenses, to reduce the carrying value of certain long-lived assets to their estimated fair value pursuant to impairment indicators for property currently held for sale, lease terminations, idle assets and branch closures.

CAPITALIZED SOFTWARE

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 and five years. Amortization begins when the software is available for its intended use. Amortization expense was $23 million, $16 million and $19 million for the years ended December 31, 2013, 2012 and 2011, respectively. Capitalized software was $107 million and $72 million at December 31, 2013 and 2012, respectively and are included in Other assets and intangibles - net on the Consolidated Balance Sheets.

GOODWILL AND OTHER INTANGIBLES

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 implied fair value of goodwill is less than its carrying value.

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 unless the estimated useful life is determined to be indefinite. Amortizable intangible assets are being amortized primarily over useful lives of three to 22 years. The straight-line method of amortization is used as it has been determined to approximate customer attrition patterns and the use pattern of the assets. Impairment losses are recognized if the carrying amount of an intangible, subject to amortization, is not recoverable from expected future cash flows and its carrying amount exceeds its fair value.

The Company also maintains intangible assets with indefinite lives, which are not amortized. These intangibles are tested for impairment on an annual basis and more often if circumstances require. Impairment losses are recognized whenever the implied fair value of these assets is less than their carrying value. See Note 2 and Note 3 to the Consolidated Financial Statements.

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. The carrying value of long-term debt also approximates fair value due to the variable interest rates. The fair value of the Company's qualifying derivative instruments is recorded in the Consolidated Balance Sheets and is discussed in more detail in Note 8 to the Consolidated Financial Statements.

DERIVATIVE INSTRUMENTS AND HEDGING

The Company uses derivative financial instruments to manage exposures to fluctuations in interest rates and foreign currency exchange rates. The Company does not enter into derivative financial instruments for trading or speculative purposes. All derivative instruments are recognized as either assets or liabilities in the balance sheet at their fair value. Changes in the fair value of derivatives are recognized in net earnings or other comprehensive earnings (losses) depending on whether the derivative is designated as part of a qualifying hedging relationship. The ineffective portion of a qualifying hedging derivative and derivatives not designated as a hedge are recognized immediately in earnings. Instruments that do not qualify for hedge accounting are marked to market with the change recognized in current period earnings. See Note 8 and Note 13 to the Consolidated Financial Statements for additional information on the Company's derivative activities.

INSURANCE RESERVES

The Company purchases insurance for catastrophic exposures and those risks required to be insured by law. It also retains a significant portion of the risk of certain losses related to workers' compensation, general liability and property losses through the utilization of high deductibles and self-insured retentions. Reserves for these potential losses are based on an external analysis of the Company's historical claims results and other actuarial assumptions.

WARRANTY RESERVES

The Company generally warrants the products it sells against defects for one year. For a significant portion of warranty claims, the manufacturer of the product is responsible for expenses. For warranty expenses not covered by the manufacturer, the Company provides a reserve for future costs based primarily on historical experience. Warranty reserves were $4 million at December 31, 2013 and 2012.

NEW ACCOUNTING STANDARDS

In February 2013, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. Under ASU 2013-02, an entity is required to provide information about the amounts reclassified out of accumulated other comprehensive income (AOCI) by component. In addition, an entity is required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of AOCI by the respective line items of net income, but only if the amount reclassified is required to be reclassified in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide details about those amounts. ASU 2013-02 does not change the current requirements for reporting net income or other comprehensive income in the financial statements. ASU 2013-02 is effective for interim and annual periods beginning after December 15, 2012 and early adoption is permitted. The Company adopted ASU 2013-02 in the first quarter of 2013. The adoption of ASU 2013-02 did not have a material impact on the consolidated financial statements.

In July 2013, the Financial Accounting Standards Board issued ASU 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. The guidance requires the presentation of certain unrecognized tax benefits as reductions to deferred tax assets rather than as liabilities in the condensed consolidated balance sheets when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The amendments will be effective for interim and annual periods beginning after December 15, 2013. Early adoption and retrospective application are permitted. The Company does not expect the adoption of ASU 2013-11 to have a material impact on the Company’s consolidated financial statements.

CONTINGENCIES AND LEGAL MATTERS

CONTINGENCIES AND LEGAL MATTERS

The Company has 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 purportedly distributed by the Company. In 2013, the Company was named in lawsuits relating to asbestos involving approximately 70 new plaintiffs, and lawsuits relating to asbestos and/or silica involving approximately 67 plaintiffs were dismissed with respect to the Company, typically based on the lack of product identification.

As of January 23, 2014, the Company is named in cases filed on behalf of approximately 1,929 plaintiffs in which there is an allegation of exposure to asbestos and/or silica. The Company has denied, or intends to deny, the allegations in all of the above-described lawsuits.  If a specific product distributed by the Company is identified in any of these lawsuits, the Company would attempt to exercise indemnification remedies against the product manufacturer.  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, coverage and costs of defense of lawsuits involving claims of exposure to asbestos.  While the Company is unable to predict the outcome of these lawsuits, 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.

As previously disclosed, on December 26, 2012, the Company announced that it entered into a definitive settlement agreement (the “Agreement”) with the United States of America, acting through the Civil Division of the United States Department of Justice (DOJ) of certain claims related to its contracts with the General Services Administration (GSA) and the United States Postal Service. The Agreement did not contain any admission of wrongdoing by the Company. The amounts due under the Agreement have been fully paid. The Company continues to maintain a $6 million reserve for liabilities associated with alleged claims for tax, freight and billing errors related to its GSA contract that were not covered by the Agreement and which remain unresolved.

From time to time the Company is involved in various other legal and administrative proceedings that are incidental to its business, including claims related to product liability, general negligence, contract disputes, environmental issues, 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 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.

Notes to Financial Statements [Abstract]

STOCK INCENTIVE PLANS

STOCK INCENTIVE PLANS

The Company maintains stock incentive plans under which the Company may grant a variety of incentive awards to employees and directors. In 2010, the Company's shareholders approved the 2010 Incentive Plan (Plan), which replaced all prior active plans (Prior Plans). Awards previously granted under Prior Plans will remain outstanding in accordance with their terms. A total of 5.9 million shares of common stock were reserved for issuance under the Plan. As of December 31, 2013, there were 1.9 million shares available for grant under the Plan. Non-qualified stock options, performance shares, restricted stock units and deferred stock units have been granted and are outstanding under these plans.

Pretax stock-based compensation expense was $52 million, $53 million and $51 million in 2013, 2012 and 2011, respectively. Related income tax benefits recognized in earnings were $17 million in 2013 and $18 million in 2012 and 2011.

Options

In 2013, 2012 and 2011, the Company issued stock option grants to employees as part of their incentive compensation. Option awards are granted with an exercise price equal to the closing market price of the Company's stock on the last trading day preceding the date of grant. The options generally vest over three years, although accelerated vesting is provided in certain circumstances. Awards generally expire 10 years from the grant date. Transactions involving stock options are summarized as follows:

	Shares Subject to Option		Weighted Average Price Per Share		Options Exercisable
Outstanding at January 1, 2011	4,881,248		$	77.61	2,486,478
Granted	520,327		$	149.15
Exercised	(1,323,883	)	$	63.08
Canceled or expired	(117,017	)	$	89.18

Outstanding at December 31, 2013	2,850,455		$	132.67	1,652,417

At December 31, 2013, there was $13 million of total unrecognized compensation expense related to nonvested option awards, which the Company expects to recognize over a weighted average period of 1.9 years.

The following table summarizes information about stock options exercised (in thousands of dollars):

	For the years ended December 31,
	2013		2012		2011
Fair value of options exercised	$	16,407	$	18,120	$	20,933

The Company uses a binomial lattice option pricing model for the valuation of stock options. The weighted average fair value of options granted in 2013, 2012 and 2011 was $51.30, $43.98 and $33.95, respectively. The fair value of each option granted in 2013, 2012 and 2011 used the following assumptions:

	For the years ended December 31,
	2013	2012	2011
Risk-free interest rate	0.9%	1.1%	2.6%
Expected life	6 years	6 years	6 years
Expected volatility	25.5%	25.9%	24.6%
Expected dividend yield	1.5%	1.6%	1.8%

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 also the primary basis for selection of expected dividend yield assumptions.

Performance Shares

The Company awards performance-based shares to certain executives. Receipt of Company stock is contingent upon the Company meeting sales growth and return on invested capital (ROIC) performance goals. Each participant is granted a base number of shares. At the end of the performance period, the number of shares granted will be increased, decreased or remain the same based upon actual Company-wide sales versus target sales. The shares, as determined at the end of the performance period, are issued at the end of the third year if the Company's average target ROIC is achieved during the vesting period.

Performance share value is based upon closing market prices on the last trading day preceding the date of award and is charged to earnings on a ratable basis over the three-year period based on the number of shares expected to vest. Holders of performance share awards are not entitled to receive cash payments equivalent to cash dividends. If the performance shares vest, they will be settled by the Company's issuance of common stock in exchange for the performance shares on a one-for-one basis. The following table summarizes the transactions involving performance-based share awards:

	2013				2012				2011
	Shares		Weighted Average Price Per Share		Shares		Weighted Average Price Per Share		Shares		Weighted Average Price Per Share
Beginning nonvested shares outstanding	117,979		$	141.86	192,740		$	109.16	177,120		$	84.74
Issued	31,553		$	191.36	28,639		$	177.75	96,236		$	127.43

Vested	(84,340	)	$	130.35	(101,734	)	$	90.47	(67,560	)	$	72.86
Ending nonvested shares  outstanding	57,533		$	185.02	117,979		$	141.86	192,740		$	109.16

At December 31, 2013, there was $5 million of total unrecognized compensation expense related to performance-based share awards that the Company expects to recognize over a weighted average period of 1.7 years.

Restricted Stock Units (RSUs)

RSUs granted vest over periods from three to seven years from issuance, although accelerated vesting is provided in certain instances. Holders of RSUs are entitled to receive 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:

	2013				2012				2011
	Shares		Weighted Average Price Per Share		Shares		Weighted Average Price Per Share		Shares		Weighted Average Price Per Share
Beginning nonvested units	978,888		$	118.60	1,119,488		$	100.76	1,205,787		$	88.65

Ending nonvested units	739,717		$	154.09	978,888		$	118.60	1,119,488		$	100.76
Fair value of shares vested (in millions)	$29				$23				$20

At December 31, 2013, there was $54 million of total unrecognized compensation expense related to nonvested RSUs that the Company expects to recognize over a weighted average period of 3.3 years.

Director Stock Awards

The Company's Board of Directors receives both cash and deferred stock units (DSUs) for its services.  A DSU is the economic equivalent of a share of common stock.  The directors were each awarded $125,000 of DSUs in 2013 and $115,000 in 2012 and 2011.  The number of units granted was based on the 200-day average stock price as of January 31 of the grant year. Compensation expense related to the DSUs is based upon the closing market price on the last trading day preceeding the date of award.  DSUs vest immediately at grant and are entitled to receive dividends and other distributions with respect to common stock, which are deferred as stock units, based on the market value of the stock at relevant times. Directors can also elect to defer their cash fees in the form of DSUs. Settlement of DSUs is required to be deferred until after termination of service as a director.  The accumulated value of DSUs is recorded in Additional contributed capital as of December 31, 2013 and 2012.  During 2012, the Board approved a change in the settlement procedure to eliminate the cash settlement option. As of December 31, 2011, the outstanding DSUs were recorded as a liability in Employment-related and other noncurrent liabilities and the Company recognized expense for appreciation in value of equivalent stock units based on the market price of the Company’s common stock in 2012 and 2011. The following table summarizes DSU activity (dollars in thousands):

	2013					2012					2011
	Units		Dollars			Units		Dollars			Units		Dollars
