(Unaudited)
1. BACKGROUND AND BASIS OF PRESENTATION
W.W. Grainger, Inc. is a broad line, business-to-business distributor of maintenance, repair and operating (MRO) products and services with operations primarily in North America, Europe and Japan. In this report, the words “Company” or “Grainger” mean W.W. Grainger, Inc. and its subsidiaries, except where the context makes it clear that the reference is only to W.W. Grainger, Inc. itself and not its subsidiaries.
The Condensed Consolidated Financial Statements (Financial Statements) of the Company and the related notes are unaudited and should be read in conjunction with the consolidated financial statements and related notes for the year ended December 31, 2018 included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (SEC) on February 28, 2019.
The Condensed Consolidated Balance Sheet as of December 31, 2018 has been derived from the audited consolidated financial statements at that date, but does not include all of the disclosures required by accounting principles generally accepted in the United States of America (U.S.) for complete financial statements.
The unaudited financial information reflects all adjustments (primarily consisting of normal recurring adjustments) which, in the opinion of management, are necessary for a fair presentation of the statements contained in this report.
2. NEW ACCOUNTING STANDARDS
In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments as modified by subsequently issued ASUs 2018-19, 2019-04 and 2019-05. This ASU requires estimating all expected credit losses for certain types of financial instruments, including trade receivables, held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. The effective date of this ASU is for fiscal years and interim periods beginning after December 15, 2019 and the Company plans to adopt this ASU prospectively. The Company is evaluating the impact of this ASU and does not expect a material impact to the Company's Financial Statements.
On January 1, 2019, the Company adopted ASU 2016-02, Leases as modified subsequently by ASUs 2018-01, 2018-10, 2018-11, 2018-20 and 2019-01(Topic 842). The core principle of these ASUs is to improve transparency and comparability related to the accounting and reporting of leasing arrangements, including balance sheet recognition for assets and liabilities associated with rights and obligations created by leases with terms greater than twelve months, among other changes.
The Company utilized the simplified modified retrospective transition method that allowed for a cumulative-effect adjustment in the period of adoption, and did not restate prior periods. Additionally, the Company elected the practical expedients package permitted under the transition guidance. Adoption of the new standard resulted in the recording of right of use (ROU) assets and lease liabilities of approximately $208 million and $205 million, respectively as of January 1, 2019 related to operating and finance leases. Adoption of the standard did not materially impact the Company’s Financial Statements. See Note 5 to the Financial Statements.
In July 2019, the FASB issued ASU 2019-07, Codification Updates to SEC Sections - Amendments to SEC Paragraphs Pursuant to SEC Final Rule Releases No. 33-10532, Disclosure Update and Simplification, and Nos. 33-10231 and 33-10442, Investment Company Reporting Modernization, and Miscellaneous Updates (SEC Update). This ASU clarifies or improves the disclosure and presentation requirements of a variety of codification topics by aligning with the SEC's regulations, thereby eliminating redundancies and making the codification easier to apply. This ASU was effective immediately upon issuance and did not have a material impact on the Company's Financial Statements and related disclosures.

3. REVENUE
Company revenue is primarily comprised of MRO product sales and related activities, such as freight and services. Total service revenue is not material and accounted for approximately 1% of the Company's revenue for the three and nine months ended September 30, 2019 and 2018, respectively.
Grainger serves a large number of customers in diverse industries, which are subject to different economic and market specific factors.

5. LEASES
The Company leases certain properties and buildings (including branches, warehouses, distribution centers and office space) and equipment under various arrangements which provide the right to use the underlying asset and require lease payments for the lease term. The Company’s lease portfolio consists mainly of operating leases which expire at various dates through 2036. Finance leases and service contracts with lease arrangements are not material and the following disclosures pertain to the Company’s operating leases.
Many of the property and building lease agreements obligate the Company to pay real estate taxes, insurance and certain maintenance costs (hereinafter referred to as non-lease components). Certain of the Company’s lease arrangements contain renewal provisions from 1 to 30 years, exercisable at the Company's option. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants.
The Company determines if an arrangement is an operating lease at inception. Leases with an initial term of 12 months or less are not recorded on the balance sheet. All other leases are recorded on the balance sheet with ROU assets representing the right to use the underlying asset for the lease term and lease liabilities representing the obligation to make lease payments arising from the lease.
ROU assets and lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term and include options to extend or terminate the lease when they are reasonably certain to be exercised. The present value of lease payments is determined primarily using the incremental borrowing rate based on the information available at lease commencement date. Lease agreements with lease and non-lease components are generally accounted for as a single lease component. The Company’s operating lease expense is recognized on a straight-line basis over the lease term and is recorded in Selling, general and administrative expenses (SG&A).

Grainger tests reporting units' goodwill and intangible assets for impairment annually during the fourth quarter and more frequently if impairment indicators exist. Accordingly, Grainger periodically performs qualitative assessments of significant events and circumstances such as reporting units' historical and current results, assumptions regarding future performance, strategic initiatives and overall economic factors to determine the existence of impairment indicators and assess if it is more likely than not that the fair value of reporting units or intangible assets is less than their carrying value and if a quantitative impairment test is necessary.
Grainger's qualitative assessment for the nine months ended September 30, 2019 did not indicate the presence of any impairment triggering events. Changes in assumptions regarding future performance, as well as the ability to execute on growth initiatives and productivity improvements, may have a significant impact on future cash flows. Likewise, an unfavorable economic environment and changes in market conditions, discount rates or other factors may result in future impairments of goodwill and intangible assets.

7. RESTRUCTURING
Restructuring activity for the three and nine months ended September 30, 2019 was not material. In the three and nine months ended September 30, 2018, the Company recorded restructuring charges of approximately $4 million and $27 million, respectively. These charges primarily consisted of involuntary employee termination costs in Canada and the U.S., net of gains from the sales of branches and are included in SG&A. The reserve balance as of September 30, 2019 and December 31, 2018 was approximately $16 million and $47 million, respectively, and is primarily included in Accrued compensation and benefits. The remaining reserves are expected to be paid through 2020.
8. SHORT-TERM AND LONG-TERM DEBT
Short-term debt consisted of outstanding lines of credit of $51 million and $49 million at September 30, 2019 and December 31, 2018, respectively. Long-term debt consisted of the following (in millions of dollars):

| As of September 30, 2019 |  | As of December 31, 2018

Long-term debt (less current maturities) | $ | 1,918 |  |  | $ | 2,161 |  |  | $ | 2,090 |  |  | $ | 2,056 |

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

9. INCOME TAXES
For the three months ended September 30, 2019, the Company's effective tax rate was 24.2% compared to 32.7% in the three months ended September 30, 2018. The higher tax rate in the prior year was driven primarily by impairment charges related to the Cromwell business in the U.K., which lowered reported operating earnings and were not tax deductible.
10. SEGMENT INFORMATION
Grainger's two reportable segments are the U.S. and Canada. The U.S. reportable segment reflects the results of Grainger's U.S. businesses. The Canada reportable segment reflects the results of Acklands-Grainger, Inc. and its subsidiaries. Other businesses include the endless assortment businesses, Zoro Tools, Inc. (Zoro) in the U.S. and MonotaRO Co. (MonotaRO) in Japan, and smaller high-touch solutions businesses in Europe, Asia and Mexico. These businesses individually do not meet the criteria of a reportable segment.

Total consolidated assets | $ | 5,922 |  |  | $ | 5,873 |  |  |  |  |

The Company is a broad-line distributor of MRO products and services. Products are regularly added and deleted from the Company's inventory. Accordingly, it would be impractical to provide sales information by product category due to the way the business is managed.
Unallocated expenses primarily relate to the Company's headquarters support services and intercompany eliminations, which are not part of any reportable segment. Unallocated expenses include supply chain, product management and procurement, finance, communications, human resources, information systems, legal and compliance, internal audit and real estate.
Assets for reportable segments include net accounts receivable and first-in, first-out inventory which are reported to the Company's Chief Operating Decision Maker. Other current and non-current assets include all other assets of the reportable segments. Unallocated assets are primarily comprised of non-operating cash and cash equivalents, property, buildings and equipment, net, and certain prepaid expenses related to the Company's headquarters support services.
11. CONTINGENCIES AND LEGAL MATTERS
From time to time the Company is involved in various legal and administrative proceedings that are incidental to its business, including claims related to product liability, general negligence, contract disputes, cybersecurity incidents, privacy matters, environmental issues, wage and hour laws, intellectual property, employment practices, advertising laws, regulatory compliance, and other matters and actions brought by employees, customers, competitors, suppliers and governmental entities. As a government contractor selling to federal, state and local governmental entities, the Company is also subject to governmental and regulatory inquiries, audits and other proceedings, including those related to contract administration and 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.

CONDITION AND RESULTS OF OPERATIONS
Item 2: Management's Discussion and Analysis of Financial Condition and Results of Operations
General
W.W. Grainger, Inc. (Grainger or the Company) is a broad line, business-to-business distributor of maintenance, repair and operating (MRO) products and services with operations primarily in North America, Europe and Japan. More than 3.5 million customers worldwide rely on Grainger for products such as safety, gloves, ladders, motors and janitorial supplies, along with services like inventory management and technical support. These customers represent a broad collection of industries (see Note 3 in the Condensed Consolidated Financial Statements (Financial Statements)). They place orders online, on mobile devices, through sales representatives, over the phone and at local branches. Approximately 5,000 suppliers provide Grainger with approximately 1.7 million products stocked in Grainger's distribution centers (DCs) and branches worldwide.
Grainger's two reportable segments are the U.S. and Canada (Acklands - Grainger Inc. and its subsidiaries). These reportable segments reflect the results of the Company's high-touch solutions businesses in those geographies. Other businesses include the endless assortment businesses, (Zoro in the U.S. and MonotaRO in Japan), and smaller high-touch solutions businesses in Europe, Asia and Mexico.
Business Environment
Given Grainger's large number of customers and the diverse industries it serves, several economic factors and industry trends tend to shape Grainger’s business environment and provide general insight into projecting Grainger's growth. Grainger’s sales in the United States (U.S.) and Canada tend to positively correlate with Business Investment, Business Inventory, Exports, Industrial Production and Gross Domestic Product (GDP). Sales in Canada also tend to positively correlate with oil prices. The table below provides these estimated indicators for 2019:

| U.S. |  | Canada
| Estimated 2018 | Forecasted 2019 |  | Estimated 2018 | Forecasted 2019
Business Investment | 6.8% | 1.6% |  | 1.2% | (2.0)%
Business Inventory | 1.8% | 2.8% |  | — | —
Exports | 3.0% | (0.2)% |  | 3.2% | 2.6%
Industrial Production | 3.9% | 0.9% |  | 3.1% | 0.8%
GDP | 2.9% | 2.3% |  | 1.9% | 1.4%
Oil Prices | — | — |  | $65/barrel | $59/barrel
Source: Global Insight U.S. (October 2019), Global Insight Canada (September 2019)

In the U.S., Business Investment and Exports are two major indicators of MRO spending. Per the Global Insight October 2019 forecast, Business Inventory is forecast to improve while Business Investment, Industrial Production, Exports and GDP are forecast to soften, as a result of the trade tensions and associated uncertainty around tariff policy, slowing global growth and a strong U.S. dollar, diminishing support from fiscal stimulus and a decline in the pace of inventory accumulation.
Per the Global Insight September 2019 forecast, Canada's Business Investment, Exports, Industrial Production and GDP are expected to slow due to elevated global trade uncertainties, a reduction in spending, delayed investments and slowing global oil demand.
Outlook
Each business in Grainger’s portfolio has a specific set of strategic imperatives focused on creating unique value for customers.
In the U.S. business, Grainger is focused on growing market share through the three pillars of its strategy: (i) building advantaged MRO solutions, which means being able to get customers the exact product they need to solve a problem quickly; (ii) offering differentiated sales and services; Grainger has an advantage in serving complex businesses at their place of business through its direct customer relationships and onsite services and (iii) delivering unparalleled customer service; Grainger is committed to providing the absolute best customer experience in the industry through its effort to deliver flawlessly on every customer transaction.

Net earnings attributable to W.W. Grainger, Inc. | $ | 233 |  |  | $ | 104 |  | 123 | % |  | 7.9 | % |  | 3.7 | %

Grainger’s net sales of $2,947 million for the third quarter of 2019 increased $116 million, or 4% compared to the same period in 2018. On a daily basis, net sales increased 2.5%. The increase in net sales was primarily driven by volume increases in the U.S. business and the endless assortment businesses, partially offset by lower sales in the Canada business and Cromwell in the United Kingdom (U.K.), which is included in other businesses. For the three months ended September 30, 2019, price inflation and foreign exchange were flat. See the Segment Analysis below for further details related to segment revenue.
Gross profit of $1,099 million for the third quarter of 2019 increased $20 million compared to the same quarter in 2018. The gross profit margin of 37.3% during the third quarter of 2019 decreased 0.8 percentage point when compared to the same quarter in 2018. This decrease was driven by the timing of pricing adjustments during the year which resulted in negative price cost spread in the U.S. business and increased net sales in the endless assortment businesses, which have a lower gross profit. See the Segment Analysis below for further details related to segment gross profit.
The table below reconciles reported Selling, general and administrative expenses (SG&A), operating earnings, net earnings attributable to W.W. Grainger, Inc. and effective tax rate determined in accordance with U.S. generally accepted accounting principles (GAAP) to adjusted SG&A, operating earnings, net earnings attributable to W.W. Grainger, Inc. and effective tax rate, which are all considered non-GAAP measures. The Company believes that these non-GAAP measures provide meaningful information to assist shareholders in understanding financial results and assessing prospects for future performance as they provide a better baseline for analyzing the ongoing performance of its businesses by excluding items that may not be indicative of core operating results. Because non-GAAP financial measures are not standardized, it may not be possible to compare these measures with other companies' non-GAAP measures having the same or similar names.

Excluding restructuring, net and impairment charges in both periods as noted in the table above, operating earnings increased $7 million or 2%, driven primarily by higher gross profit dollars.
Other expense, net was $16 million for the third quarter of 2019, a decrease of $2 million, or 16% compared to the third quarter of 2018. The decrease was primarily due to lower losses from the Company's clean energy investments which were concluded in the second half of 2018.
Income taxes of $78 million for the third quarter of 2019 increased $22 million, or 39% compared to the third quarter of 2018. Grainger's effective tax rates were 24.2% and 32.7% for the three months ended September 30, 2019 and 2018, respectively. The higher tax rate in the prior year quarter was driven primarily by Cromwell impairment charges which lowered reported operating earnings and were not tax deductible. Excluding restructuring, net and impairment charges in both periods as noted in the table above, the effective tax rates were 24.2% and 20.0% for the three months

W.W. Grainger, Inc. and Subsidiaries
MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS
ended September 30, 2019 and 2018, respectively. The increase in effective tax rate was primarily driven by lower tax benefit from stock-based compensation and the absence of the Company's clean energy tax benefits in 2019 as the Company concluded its investment in 2018.
Net earnings attributable to W.W. Grainger, Inc. of $233 million for the third quarter of 2019 increased $129 million or 123% compared to the third quarter of 2018. Excluding restructuring, net and impairment charges from both periods in the table above, net earnings decreased $7 million or 3%.
Diluted earnings per share of $4.25 in the third quarter of 2019 was up 134% versus the $1.82 for the third quarter of 2018, primarily due to higher net earnings and lower average shares outstanding, partially offset by higher taxes due to lower tax benefits from stock-based compensation. Excluding restructuring, net and impairment charges from both periods in the table above, diluted earnings per share of $4.26 in the third quarter of 2019 increased 2% from $4.19 for the third quarter of 2018.
Segment Analysis
The following results at the U.S. and Canada segments and Other businesses level include external and intersegment net sales and operating earnings. See Note 10 to the Financial Statements.
United States
Net sales were $2,277 million for the third quarter of 2019, an increase of $89 million, or 4% compared to the same period in 2018. On a daily basis, net sales increased 2.5% and consisted of the following:

| Percent Increase/(Decrease)
Volume | 2.5%
Intercompany sales to Zoro (included in other businesses) | 0.5
Other | (0.5)
Total | 2.5%

Overall, revenue increases were primarily driven by market share gains. Price inflation was flat. See Note 3 to the Financial Statements for information related to disaggregated revenue.
The gross profit margin for the third quarter of 2019 decreased 0.8 percentage point compared to the same period in 2018, driven by the timing of pricing adjustments during the year which resulted in negative price cost spread.
SG&A in the third quarter of 2019 was flat when compared to the third quarter of 2018.
Operating earnings of $343 million for the third quarter of 2019 increased $17 million, or 5% from $326 million for the third quarter of 2018. This increase was driven primarily by SG&A leverage.
Canada
Net sales were $129 million for the third quarter of 2019, a decrease of $20 million, or 14% compared to the same period in 2018. On a daily basis, net sales decreased 15.5%, or 14.5% in local currency and consisted of the following:

| Percent (Decrease)/Increase
Volume | (15.5)%
Foreign exchange | (1.0)
Price | 1.0

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS
The gross profit margin increased 0.5 percentage points in the third quarter of 2019 versus the third quarter of 2018, driven by inventory management efficiencies, partially offset by negative price cost spread.
SG&A decreased 19% in the third quarter of 2019 compared to the third quarter of 2018. Excluding restructuring costs in both periods as noted in the table above, SG&A would have decreased 22%, primarily due to the 2018 cost take out actions.
Operating earnings was break even for the third quarter of 2019 compared to operating losses of $4 million in the third quarter of 2018. Excluding restructuring, net in both periods as noted in the table above, operating earnings would have been $1 million compared to operating losses of $4 million in the prior period primarily due higher gross profit and lower SG&A.
Other businesses
Net sales were $673 million for the third quarter of 2019, an increase of $63 million, or 11% when compared to the same period in 2018. On a daily basis, net sales increased 9.0%. The increase in net sales was due to strong growth in the endless assortment businesses.
The gross profit margin decreased 1.3 percentage points in the third quarter of 2019 versus the third quarter 2018, driven by higher promotional activities, freight headwinds and mix in the endless assortment businesses.
Operating earnings of $30 million for the third quarter of 2019 were up $129 million compared to operating losses of $99 million for the third quarter of 2018. Other businesses' 2018 results included impairment charges relating to the Cromwell business in the U.K. Excluding restructuring, net and impairment charges in both periods as noted in the table above, operating earnings would have decreased $11 million or 26%. This decrease is primarily due to the endless assortment businesses' investments to drive long-term growth and under performance in the international high-touch solutions businesses.
Matters Affecting Comparability
There were 191 sales days in the nine months ended September 30, 2019 and 2018.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS
Grainger’s net sales of $8,639 million for the nine months ended September 30, 2019 increased $181 million, or 2% compared to the same period in 2018 and consisted of the following:

| Percent Increase/(Decrease)
Volume | 2.5%
Price | 0.5
Foreign exchange | (0.5)
Other | (0.5)
Total | 2.0%

The increase in net sales was primarily driven by volume increases in the U.S. business due to market share gain and continued double digit growth in the endless assortments businesses, offset by lower sales in the Canada business and other businesses. See the Segment Analysis below for further details related to segment revenue.
Gross profit of $3,315 million for the nine months ended September 30, 2019 increased $33 million, or 1% compared to the same period in 2018. The gross profit margin of 38.4% decreased 0.4 percentage point when compared to the same period in 2018, primarily driven by the endless assortment businesses.
The table below reconciles reported SG&A, operating earnings and net earnings attributable to W.W. Grainger, Inc. determined in accordance with U.S. GAAP to adjusted SG&A, operating earnings and net earnings attributable to W.W. Grainger, Inc., which are all considered non-GAAP measures. The Company believes that these non-GAAP measures provide meaningful information to assist shareholders in understanding financial results and assessing prospects for future performance as they provide a better baseline for analyzing the ongoing performance of its businesses by excluding items that may not be indicative of core operating results. Because non-GAAP financial measures are not standardized, it may not be possible to compare these measures with other companies' non-GAAP measures having the same or similar names. All tables below are in millions of dollars:

(1) The tax impact of adjustments is calculated based on the income tax rate in each applicable jurisdiction, subject to deductibility limitations and the Company's ability to realize the associated tax benefits.
SG&A of $2,234 million for the nine months ended September 30, 2019 decreased $180 million, or 7% from $2,414 million for the nine months ended September 30, 2018. Excluding restructuring, net in both periods as noted in the table above, SG&A decreased $14 million, or 1% primarily due to 2018 cost take-out actions in Canada.
Operating earnings for the nine months ended September 30, 2019 were $1,081 million, an increase of $213 million, or 24% compared to the same period in 2018. Excluding restructuring, net in both periods as noted in the table above, operating earnings increased $47 million or 5%, driven primarily by cost take-out actions in the Canadian business and SG&A leverage in the U.S. business.
Other expense, net was $42 million for the nine months ended September 30, 2019, a decrease of $24 million, or 38% compared to the nine months ended September 30, 2018. The decrease was primarily due to lower losses from the Company's clean energy investments which were concluded in the second half of 2018.
Income taxes of $261 million for the nine months ended September 30, 2019 increased $63 million, or 32% compared with $198 million for the comparable 2018 period. Grainger's effective tax rates were 25.1% and 24.7% for the nine months ended September 30, 2019 and 2018, respectively. The increase was primarily driven by lower tax benefit from stock-based compensation and the absence of the Company's clean energy tax benefits in 2019 as the Company concluded its investments in 2018.
Net earnings attributable to W.W. Grainger, Inc. for the nine months ended September 30, 2019 increased $173 million or 30% to $746 million from $573 million for the nine months ended September 30, 2018. Excluding restructuring, net from both periods in the table above, net earnings increased $19 million, or 3%. The increase in net earnings primarily resulted from lower SG&A and lower other expense, net.
Diluted earnings per share of $13.40 in the nine months ended September 30, 2019 was up 33% versus the $10.04 for the same period in 2018, due to higher earnings and lower average shares outstanding. Excluding restructuring, net from both periods in the table above, diluted earnings per share would have been $13.40 compared to $12.74 in 2018, an increase of 5%.

| Percent (Decrease)/Increase
Volume | (21.5)%

Price | 2.5
Total | (21.5)%

For the nine months ended September 30, 2019, volume was down 21.5 percentage points compared to the same period in 2018 due to customer disruption as a result of actions taken to reduce the branch footprint and sales coverage optimization activities.
The gross profit margin decreased 1.1 percentage points in the nine months ended September 30, 2019 compared to the nine months ended September 30, 2018, primarily due to negative price cost spread.
SG&A decreased $73 million, or 36% in the nine months ended September 30, 2019 compared to the nine months ended September 30, 2018. Excluding restructuring, net in both periods as noted in the table above, SG&A would have decreased $48 million, or 27% compared to the prior period.

Excluding restructuring, net in both periods as noted in the table above, operating losses would have been $5 million compared to $15 million in the prior period primarily due to lower gross profit, partially offset by lower SG&A.

Other businesses
Net sales for other businesses were $1,969 million for the nine months ended September 30, 2019 an increase of $149 million, or 8% compared to the same period in 2018 and consisted of the following:

| Percent Increase/(Decrease)

The net sales increase was primarily due to customer acquisition growth from the endless assortment businesses, partially offset by foreign exchange headwinds from the euro and pound sterling.
Operating earnings of $87 million for the nine months ended September 30, 2019 increased $109 million from operating losses of $22 million in the comparable period from the prior year. Other businesses' 2018 results included impairment charges relating to the Cromwell business in the U.K. Excluding restructuring, net and impairment charges in both periods as noted in the table above, operating earnings would have decreased $34 million or 28%.This decrease is primarily due to the endless assortment businesses' investments to drive long-term growth and performance in the high-touch solutions businesses.
Financial Condition
Cash Flow
Net cash provided by operating activities was $770 million and $743 million for the nine months ended September 30, 2019 and 2018, respectively. The increase in cash provided by operating activities is primarily the result of higher net earnings and favorable changes in working capital, partially offset by higher income tax payments and higher net payments related to employee variable compensation and benefits paid under annual incentive plans.
Net cash used in investing activities was $145 million and $105 million for the nine months ended September 30, 2019 and 2018, respectively. This increase in net cash used in investing activities was primarily driven by lower proceeds from the sales of assets when compared to the prior year.
Net cash used in financing activities was $875 million and $437 million in the nine months ended September 30, 2019 and 2018, respectively. The increase in net cash used in financing activities was primarily driven by higher treasury stock repurchases in 2019 compared to 2018.
Working Capital
Internally generated funds are the primary source of working capital and funds used for growth initiatives and capital expenditures. Grainger's working capital is not impacted by significant seasonality trends throughout the year.
Working capital consists of current assets (less non-operating cash) and current liabilities (less short-term debt, current maturities of long-term debt and lease liabilities). Working capital at September 30, 2019, was $2,059 million, an increase of $161 million when compared to $1,898 million at December 31, 2018. The increase was primarily driven by an increase in accounts receivable and a decrease in accrued contributions to employees profit-sharing plans due to the annual cash contribution. At these dates, the ratio of current assets to current liabilities was 2.6 and 2.4, respectively.
Debt
Grainger maintains a debt ratio and liquidity position that provides flexibility in funding working capital needs and long-term cash requirements. In addition to internally generated funds, Grainger has various sources of financing available, including bank borrowings under lines of credit. Total debt, which is defined as total interest-bearing debt (short-term, current maturities and long-term) and lease liabilities as a percent of total capitalization was 53.7% at September 30, 2019, and 51.5% at December 31, 2018.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS
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 about future events that affect the amounts reported in the financial statements and accompanying notes.
Accounting estimates are considered critical when they require management to make subjective and complex judgments, estimates and assumptions about matters that have a material impact on the presentation of Grainger’s financial statements and accompanying notes. For a description of Grainger’s critical accounting estimates, see Grainger's Annual Report on Form 10-K for the fiscal year ended December 31, 2018.
Management has discussed the development and selection of these critical accounting estimates with the Audit Committee of the Board of Directors and with the Company's independent registered public accounting firm.
Forward-Looking Statements
From time to time, in this Quarterly Report on Form 10-Q, as well as in other written reports, communications and verbal statements, Grainger makes forward-looking statements that are not historical in nature but concern forecasts of future results, business plans, analyses, prospects, strategies, objectives and other matters that may be deemed to be “forward-looking statements” under the federal securities laws. Forward-looking statements can generally be identified by their use of terms such as “anticipate,” “estimate,” “believe,” “expect,” “could,” “forecast,” “may,” “intend,” “plan,” “predict,” “project” “will” or “would” and similar terms and phrases, including references to assumptions.
Grainger cannot guarantee that any forward-looking statement will be realized and achievement of future results is subject to risks and uncertainties, many of which are beyond the Company’s control, which could cause Grainger’s results to differ materially from those that are presented.
Important factors that could cause actual results to differ materially from those presented or implied in the forward-looking statements include, without limitation: higher product costs or other expenses; a major loss of customers; loss or disruption of sources of supply; increased competitive pricing pressures; failure to develop or implement new technology initiatives or business strategies; failure to adequately protect intellectual property or successfully defend against infringement claims; the implementation, timing and results of the Company’s strategic pricing initiatives and other responses to market pressures; the outcome of pending and future litigation or governmental or regulatory proceedings, including with respect to wage and hour, anti-bribery and corruption, environmental, advertising, privacy and cybersecurity matters; investigations, inquiries, audits and changes in laws and regulations; disruption of information technology or data security systems; general industry, economic, market or political conditions; general global economic conditions; currency exchange rate fluctuations; market volatility, including volatility or price declines of the Company’s common stock; commodity price volatility; labor shortages; facilities disruptions or shutdowns; higher fuel costs or disruptions in transportation services; natural and other catastrophes; unanticipated and/or extreme weather conditions; loss of key members of management; the Company’s ability to operate, integrate and leverage acquired businesses; changes in effective tax rates and other factors identified under Item 1A: Risk Factors in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018, as updated in the Company’s Quarterly Reports on Form 10-Q.
Caution should be taken not to place undue reliance on Grainger’s forward-looking statements and Grainger undertakes no obligation to update or revise any of its forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.
