NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1.    BACKGROUND AND BASIS OF PRESENTATION

 

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.  W.W. Grainger, Inc.’s operations are primarily in the United States and Canada, with a presence in Europe, Asia and Latin America.  In this report, the words “Company” or “Grainger” mean W.W. Grainger, Inc. and its subsidiaries.

 

The Condensed Consolidated 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, 2012 included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (SEC).

 

The Condensed Consolidated Balance Sheet as of December 31, 2012 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 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 herein.

2.    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.

 

3.    DIVIDEND

 

On October 30, 2013, the Company’s Board of Directors declared a quarterly dividend of 93 cents per share, payable December 1, 2013, to shareholders of record on November 11, 2013.

4.    ACQUISITION

On August 23, 2013, the Company acquired E&R Industrial Sales, Inc. (E&R Industrial). 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 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. Due to the immaterial nature of this transaction, disclosure of pro forma results were not considered necessary. E&R Industrial's operating results will be included beginning with the fourth quarter of 2013 due to the timing of the acquisition. E&R Industrial's results were immaterial to the Company for the third quarter of 2013.

5.    SHORT-TERM DEBT

On August 22, 2013, the Company replaced an existing $400 million line of credit with a new $600 million line of credit to be used for general corporate purposes. The terms of the new line of credit are substantially the same as the previous line and do not contain any financial performance covenants. There were no borrowings under this new line of credit or the previous line of credit.

6.    DERIVATIVE INSTRUMENTS

 

The fair values of the significant derivative instruments for the Company were as follows (in thousands of dollars):

Derivatives Designated as Hedges		Sep 30, 2013				Dec 31, 2012
Interest rate swap		$	3,018			$	4,120
Foreign currency forwards		$	3,477			$	7,916

The Company uses derivative instruments to manage a portion of 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. The fair values of these significant derivative instruments are included in Employment-related and other non-current liabilities on the balance sheet.

The fair values of these 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. These instruments qualify for hedge accounting and the changes in fair value are reported as a component of other comprehensive earnings (losses) net of tax effects.

7.    EMPLOYEE BENEFITS - POSTRETIREMENT

 

The Company has a postretirement healthcare benefits plan that provides coverage for a majority of its United States employees 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.

The net periodic benefit costs charged to operating expenses, which are valued at the measurement date of January 1 and recognized evenly throughout the year, consisted of the following components (in thousands of dollars):

	Three Months Ended September 30,								Nine Months Ended September 30,
	2013				2012				2013				2012
Service cost	$	2,647			$	5,014			$	7,941			$	15,043
Interest cost	2,234				3,203				6,703				9,608
Expected return on assets	(1,769		)		(1,553		)		(5,307		)		(4,659		)
Amortization of transition asset	(36		)		(36		)		(107		)		(107		)
Amortization of unrecognized losses	931				1,207				2,793				3,621
Amortization of prior service credits	(1,853		)		(123		)		(5,558		)		(371		)
Net periodic benefit costs	$	2,154			$	7,712			$	6,465			$	23,135

 

For the nine months of 2013, the net periodic benefit costs decreased $17 million driven primarily by plan design changes that went into effect on January 1, 2013. Covered employees as of December 31, 2012, will remain eligible for retiree health benefits with the employee contribution structure modified for certain employees based on minimum age and service requirements. Employees hired after January 1, 2013, will not be eligible for retiree health benefits.

The Company has established a Group Benefit Trust to fund the plan and process benefit payments. The funding of the trust is an estimated amount which 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. During the three and nine months ended September 30, 2013, the Company contributed $1.4 million and $3.6 million, respectively, to the trust.

8.    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 operations in Europe, Asia, Latin America and other U.S. operations. These other businesses individually do not meet the definition 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.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

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 and direct marketing materials and eCommerce. Grainger serves approximately 2 million customers worldwide through a network of highly integrated branches, distribution centers, multiple websites and export services.

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:

	2013 Forecasted Growth
	United States		Canada
GDP	1.5%		1.6%
Industrial Production	2.4%		1.3%
Exports	2.4%		4.3%
Business Investment	3.5%		1.8%
Business Inventory	2.7%		—
Source: Global Insight (October 2013)

According to the Federal Reserve, overall industrial production increased 3.2% from September 2012 to September 2013. This improvement positively affected Grainger's sales growth for the nine months of 2013. In addition, the light and heavy manufacturing customer end-markets have historically correlated with manufacturing employment levels and manufacturing output. The United States Department of Labor reported an increase of 0.3% in manufacturing employment levels from September 2012 to September 2013. According to the Federal Reserve, manufacturing output increased 2.6% from September 2012 to September 2013. Grainger’s heavy and light manufacturing customer end-markets outperformed these indicators as sales to these customer end-markets increased in the mid-single digits and high single digits, respectively, for the nine months of 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 Bloomberg, crude oil prices have increased from $95 to $106 per barrel, or a 12% increase from September 2012 to September 2013.

Outlook

On October 16, 2013, Grainger narrowed the 2013 sales growth guidance from a range of 5 to 8 percent to a range of 5 to 6 percent and also narrowed the 2013 earnings per share guidance from a range of $11.40 to $12.00 to a range of $11.45 to $11.65. These revised estimates reflect performance in the first nine months of the year, including ongoing growth and infrastructure investments, a softer global economy and unfavorable foreign exchange.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL

CONDITION AND RESULTS OF OPERATIONS

Matters Affecting Comparability

There were 64 and 63 sales days in the third quarter of 2013 and 2012, respectively. Grainger completed several acquisitions throughout 2012 and 2013, all of which were immaterial individually and in the aggregate. Grainger’s operating results have typically included the results of each business acquired since the respective acquisition dates, however, E&R Industrial's operating results will not be included until the fourth quarter of 2013 due to the timing of the acquisition.

Results of Operations – Three Months Ended September 30, 2013

The following table is included as an aid to understanding the changes in Grainger’s Condensed Consolidated Statements of Earnings:

	Three Months Ended September 30,
	As a Percent of Net Sales						Percent Increase/(Decrease)
	2013			2012
Net sales	100.0	%		100.0	%		5.1	%
Cost of merchandise sold	56.2			56.4			4.7
Gross profit	43.8			43.6			5.8
Operating expenses	29.3			32.4			(4.7	)
Operating earnings	14.5			11.2			36.3
Other income (expense)	(0.1	)		(0.2	)		(20.9	)
Income taxes	5.5			4.1			40.8
Noncontrolling interest	0.1			0.1			(5.1	)
Net earnings attributable to W.W. Grainger, Inc.	8.8	%		6.8	%		35.6	%

Grainger’s net sales of $2,399 million for the third quarter of 2013 increased 5% compared with sales of $2,281 million for the comparable 2012 quarter. On a daily basis, sales increased 4%. The 4% daily increase for the quarter consisted of the following:

	Percent Increase/(Decrease)
Volume	4
Business acquisitions	1
Foreign exchange	(1)
Total	4%

Sales to all customer end markets, except resellers, increased in the third quarter of 2013. The increase in net sales was led by growth in sales to light manufacturing, natural resources and heavy manufacturing customers. Refer to the Segment Analysis below for further details.

Gross profit of $1,051 million for the third quarter of 2013 increased 6%. The gross profit margin during the third quarter of 2013 increased 0.2 percentage point when compared to the same period in 2012, primarily driven by cost savings from freight consolidation and higher supplier rebates, partially offset by unfavorable customer mix from stronger sales to large customers, which carry lower margins.

Operating expenses of $705 million for the third quarter of 2013 decreased 5%. Operating expenses in the third quarter of 2012 included $76 million of reserves related to the resolution of government contract issues. Excluding these expenses, operating expenses increased 6% primarily driven by payroll and benefits and an incremental $40 million in spending to fund Grainger's growth and infrastructure investments.

Operating earnings for the third quarter of 2013 were $347 million, an increase of 36% compared to the third quarter of 2012. Excluding the $76 million of reserves in the third quarter of 2012, operating earnings increased 5%. The increase in operating earnings was primarily driven by higher sales and improved gross profit margins.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL

CONDITION AND RESULTS OF OPERATIONS

Net earnings attributed to W.W. Grainger, Inc. for the third quarter of 2013 increased by 36% to $211 million from $155 million in the third quarter of 2012. Diluted earnings per share of $2.95 in the third quarter of 2013 were 37% higher than the $2.15 for the third quarter of 2012. The previously mentioned $76 million of reserves had a $0.66 earnings per share impact on the third quarter of 2012. Excluding this impact, earnings per share increased 5% versus 2012, due to higher earnings and lower average shares outstanding.

Segment Analysis

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.

The following comments at the segment and business unit level include external and intersegment net sales and operating earnings. See Note 8 to the Condensed Consolidated Financial Statements.

United States

Net sales were $1,905 million for the third quarter of 2013, an increase of $128 million, or 7%, when compared with net sales of $1,777 million for the same period in 2012. On a daily basis, sales increased 6%. The 6% daily increase for the quarter consisted of the following:

	Percent Increase
Volume	5
Business acquisitions	1
Total	6%

The increase in net sales was led by high single digit growth to light manufacturing customers, followed by mid-single digit growth to heavy manufacturing, commercial service and natural resource customers. Government, contractor and retail customers were up in the low single digits and net sales to resellers were down in the low single digits.

The gross profit margin for the third quarter of 2013 decreased 0.3 percentage point compared to the same period in 2012, primarily driven by negative product and customer mix due to strong sales to large customers, which carry lower margins.

Operating expenses were down 8% in the third quarter of 2013 versus the third quarter of 2012. Operating expenses in the third quarter of 2012 included $76 million of reserves related to the resolution of government contract issues. Excluding these expenses, operating expenses increased 7% driven by an incremental $36 million in growth and infrastructure spending on areas such as eCommerce, sales force expansion and inventory management solutions.

Operating earnings of $342 million for the third quarter of 2013 increased 39% from $247 million for the third quarter of 2012. Excluding the $76 million of reserves recorded in the third quarter of 2012, operating earnings increased 6%, driven by higher sales and positive operating expense leverage.

Canada

Net sales were $271 million for the third quarter of 2013, a decrease of $2 million, or 1%, when compared with $273 million for the same period in 2012. On a daily basis, sales decreased 2% (increased 2% in local currency). The 2% daily decrease for the quarter consisted of the following:

	Percent Increase/(Decrease)
Volume	2
Foreign Exchange	(4)
Total	(2)%

Sales performance in Canada was driven by double digit growth in the oil and gas end market, followed by high single digit growth to forestry, light manufacturing and utilities customers. Sales to heavy manufacturing, construction and retail end markets were down in the mid-single digits.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL

CONDITION AND RESULTS OF OPERATIONS

 

The gross profit margin increased 0.4 percentage point in the third quarter of 2013 versus the third quarter of 2012, due to cost savings from freight consolidation and higher supplier rebates.

Operating expenses were up 4% in the third quarter of 2013 versus the third quarter of 2012. In local currency, operating expenses increased 8%, primarily due to incremental spending related to a new information technology (IT) system scheduled for implementation in late 2014 and higher volume-related payroll expenses, partially offset by lower bonus expense.

Operating earnings of $32 million for the third quarter of 2013 were down $2 million, or 7%, over the third quarter of 2012. In local currency, operating earnings decreased by 3%, driven primarily by incremental spending relating to the new IT system.

Other Businesses

Net sales for other businesses, which include operations in Europe, Asia, Latin America and other U.S. operations, were $258 million for the third quarter of 2013, an increase of $3 million, or 1%, when compared with net sales of $255 million for the same period in 2012. On a daily basis, sales were flat. The drivers of net sales for the quarter consisted of the following:

	Percent Increase/(Decrease)
Volume/Price	7
Foreign exchange	(7)
Total	0%

Operating earnings were $6 million in the third quarter of 2013, compared to $9 million in the third quarter of 2012. The earnings decline for the quarter versus prior year was primarily driven by weaker performance in Mexico, Colombia and Brazil, partially offset by improved earnings from Zoro Tools.

Income Taxes

Grainger’s effective income tax rates were 38.0% and 37.1% for the three months ended September 30, 2013 and 2012, respectively. The increase was primarily due to lower earnings in foreign jurisdictions with lower tax rates.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL

CONDITION AND RESULTS OF OPERATIONS

The increase in net sales was led by double digit growth in the forestry end market, followed by high single digit growth to contractors, oil and gas and light manufacturing customers. The heavy manufacturing and government segments were down in the low single digits.

The gross profit margin increased 0.6 percentage point in the nine months of 2013 versus the nine months of 2012, primarily driven by cost savings from freight consolidation, higher supplier rebates and stronger sales of private label products.

Operating expenses were up 3% in the nine months of 2013 versus the nine months of 2012. In local currency, operating expenses increased 5%, primarily due to higher volume-related payroll, professional services and incremental spending related to a new IT system, partially offset by lower bad debt expense.

Operating earnings of $102 million for the nine months of 2013 were up $4 million, or 5%, over the nine months of 2012. In local currency, operating earnings increased 7% in the nine months of 2013 over the same period in 2012. The increase in earnings was due to sales growth and improved gross profit margins.

Other Businesses

Net sales for other businesses, which include operations in Europe, Asia, Latin America and other U.S. operations, were $768 million for the nine months of 2013, an increase of $25 million, or 3%, when compared with $743 million for the same period in 2012.

Foreign exchange	(6)
Total	3%

CONDITION AND RESULTS OF OPERATIONS

Financial Condition

Cash Flow

Cash from operating activities continues to serve as Grainger’s primary source of liquidity. Net cash provided by operating activities was $740 million and $576 million for the nine months ended September 30, 2013 and 2012, respectively. The primary contribution to cash flows from operating activities was net earnings of $648 million in the nine months ended September 30, 2013 compared to $540 million in the nine months of 2012. In addition, changes in operating assets and liabilities resulted in a net use of cash of $69 million in the nine months of 2013 compared to $117 million in the nine months of 2012. The lower use of cash for operating assets and liabilities was driven primarily by timing on accounts payable and lower inventory purchases for the nine months of 2013 compared to the nine months of 2012. Inventory purchases were down for the nine months of 2013 due to a higher inventory balance at the beginning of the year as a result of lower sales in December of 2012 and an inventory build at the end of 2012 to facilitate the move of Grainger's Chicago-area distribution center.

Net cash used in investing activities was $273 million and $174 million for the nine months ended September 30, 2013 and 2012, respectively. Cash paid for business acquisitions of $128 million was primarily driven by the acquisition of E&R Industrial in the third quarter of 2013 and the purchase of the remaining interest of the business in Colombia in the second quarter of 2013. Cash expended for additions to property, buildings, equipment and capitalized software was $148 million in the nine months ended September 30, 2013, compared to $155 million in 2012.

Net cash used in financing activities was $368 million and $322 million for the nine months ended September 30, 2013 and 2012, respectively. The $46 million increase in cash used in financing activities for the nine months ended September 30, 2013 was due to an increase in dividends paid and a net decrease in long-term debt.

Working Capital

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 at September 30, 2013, was $1,668 million, an increase of $64 million when compared to $1,604 million at December 31, 2012. The working capital assets to working capital liabilities ratio increased to 2.7 at September 30, 2013, from 2.6 at December 31, 2012. The increase primarily related to higher receivable balances and lower profit sharing accruals due to the timing of annual payments.

Debt

Grainger maintains a debt ratio and liquidity position that provide 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 as a percent of total capitalization was 14.0% at September 30, 2013, and 15.3% at December 31, 2012.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL

CONDITION AND RESULTS OF OPERATIONS

Critical Accounting Policies and 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. For a description of Grainger’s critical accounting policies see Grainger's Annual Report on Form 10-K for the year ended December 31, 2012.

Forward-Looking Statements

This Form 10-Q 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, believes, continues, could, earnings per share guidance, estimate, estimated, expected, expecting, forecasted, guidance, intended, intends, historically correlated, may, not expected, possible, projected, projecting, projections, proposed, provide, range, reasonably likely, sales growth guidance, scheduled, should, subject to, tend, tended, tend to correlate, tend to shape, trends, unanticipated, uncertainties, will, will remain" 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 which 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; facilities disruptions or shutdowns; higher fuel costs or disruptions in transportation services; natural and other catastrophes and unanticipated weather conditions.

 

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.

NEW ACCOUNTING STANDARDS	9 Months Ended

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
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.

EMPLOYEE BENEFITS	9 Months Ended
	Sep. 30, 2013
Defined Benefit Plans and Other Postretirement Benefit Plans Disclosures [Abstract]
EMPLOYEE BENEFITS	EMPLOYEE BENEFITS - POSTRETIREMENT   The Company has a postretirement healthcare benefits plan that provides coverage for a majority of its United States employees 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. The net periodic benefit costs charged to operating expenses, which are valued at the measurement date of January 1 and recognized evenly throughout the year, consisted of the following components (in thousands of dollars):   Three Months Ended September 30,   Nine Months Ended September 30,   2013   2012   2013   2012 Service cost $ 2,647   $ 5,014   $ 7,941   $ 15,043 Interest cost 2,234   3,203   6,703   9,608 Expected return on assets (1,769 )   (1,553 )   (5,307 )   (4,659 ) Amortization of transition asset (36 )   (36 )   (107 )   (107 ) Amortization of unrecognized losses 931   1,207   2,793   3,621 Amortization of prior service credits (1,853 )   (123 )   (5,558 )   (371 ) Net periodic benefit costs $ 2,154   $ 7,712   $ 6,465   $ 23,135   For the nine months of 2013, the net periodic benefit costs decreased $17 million driven primarily by plan design changes that went into effect on January 1, 2013. Covered employees as of December 31, 2012, will remain eligible for retiree health benefits with the employee contribution structure modified for certain employees based on minimum age and service requirements. Employees hired after January 1, 2013, will not be eligible for retiree health benefits. The Company has established a Group Benefit Trust to fund the plan and process benefit payments. The funding of the trust is an estimated amount which 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. During the three and nine months ended September 30, 2013, the Company contributed $1.4 million and $3.6 million, respectively, to the trust.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS	DERIVATIVE INSTRUMENTS   The fair values of the significant derivative instruments for the Company were as follows (in thousands of dollars): Derivatives Designated as Hedges   Sep 30, 2013   Dec 31, 2012 Interest rate swap   $ 3,018   $ 4,120 Foreign currency forwards   $ 3,477   $ 7,916 The Company uses derivative instruments to manage a portion of 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. The fair values of these significant derivative instruments are included in Employment-related and other non-current liabilities on the balance sheet. The fair values of these 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. These instruments qualify for hedge accounting and the changes in fair value are reported as a component of other comprehensive earnings (losses) net of tax effects.

Segment Reporting [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 operations in Europe, Asia, Latin America and other U.S. operations. These other businesses individually do not meet the definition 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. Following is a summary of segment results (in thousands of dollars):   Three Months Ended September 30, 2013   United States   Canada   Other Businesses   Total Total net sales $ 1,904,552   $ 270,660   $ 258,442   $ 2,433,654 Intersegment net sales (34,801 )   (35 )   (288 )   (35,124 ) Net sales to external customers $ 1,869,751   $ 270,625   $ 258,154   $ 2,398,530 Segment operating earnings $ 342,420   $ 31,798   $ 6,182   $ 380,400      Three Months Ended September 30, 2012   United States   Canada   Other Businesses   Total Total net sales $ 1,776,749   $ 272,943   $ 254,817   $ 2,304,509 Intersegment net sales (23,049 )   (55 )   (200 )   (23,304 ) Net sales to external customers $ 1,753,700   $ 272,888   $ 254,617   $ 2,281,205 Segment operating earnings $ 247,054   $ 34,247   $ 8,778   $ 290,079   Nine Months Ended September 30, 2013   United States   Canada   Other Businesses   Total Total net sales $ 5,542,202   $ 842,446   $ 767,598   $ 7,152,246 Intersegment net sales (90,825 )   (186 )   (709 )   (91,720 ) Net sales to external customers $ 5,451,377   $ 842,260   $ 766,889   $ 7,060,526 Segment operating earnings $ 1,012,192   $ 101,953   $ 27,232   $ 1,141,377      Nine Months Ended September 30, 2012   United States   Canada   Other Businesses   Total Total net sales $ 5,219,559   $ 825,443   $ 742,904   $ 6,787,906 Intersegment net sales (63,178 )   (261 )   (542 )   (63,981 ) Net sales to external customers $ 5,156,381   $ 825,182   $ 742,362   $ 6,723,925 Segment operating earnings $ 856,701   $ 97,502   $ 30,737   $ 984,940   United States   Canada   Other Businesses   Total Segment assets:               September 30, 2013 $ 1,990,795   $ 373,392   $ 366,131   $ 2,730,318 December 31, 2012 $ 1,884,102   $ 387,915   $ 347,905   $ 2,619,922 Following are reconciliations of segment information with the consolidated totals per the financial statements (in thousands of dollars):   Three Months Ended September 30,   Nine Months Ended September 30,   2013   2012   2013   2012 Operating earnings:           Total operating earnings for operating segments $ 380,400   $ 290,079   $ 1,141,377   $ 984,940 Unallocated expenses and eliminations (33,685 )   (35,753 )   (101,286 )   (112,253 ) Total consolidated operating earnings $ 346,715   $ 254,326   $ 1,040,091   $ 872,687     Sep 30, 2013   Dec 31, 2012 Assets:   Total assets for operating segments $ 2,730,318   $ 2,619,922 Other current and non-current assets 2,053,631   1,967,480 Unallocated assets 467,600   427,196 Total consolidated assets $ 5,251,549   $ 5,014,598 Assets for operating segments include net accounts receivable and first-in, first-out inventory which are reported to the Company's Chief Operating Decision Maker.

Unallocated expenses include payroll and benefits, depreciation and other costs associated with headquarters-related support services. Unallocated assets include non-operating cash and cash equivalents, certain prepaid expenses and property, buildings and equipment-net.
