EATON CORPORATION
NOTES TO THE FIRST QUARTER 2010 CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Millions of dollars and shares unless indicated otherwise (per share data assume dilution)

PREPARATION OF FINANCIAL STATEMENTS

The accompanying unaudited condensed consolidated financial statements of Eaton Corporation (Eaton) have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. However, in the opinion of management, all adjustments (consisting of normal recurring accruals) have been made that are necessary for a fair presentation of financial position, results of operations and cash flows for the stated periods. Management has evaluated subsequent events through the date the financial statements were filed with the SEC, noting no events that require adjustment of, or disclosure in, the consolidated financial statements for the period ended March 31, 2010. These financial statements should be read in conjunction with the consolidated financial statements and related notes included in Eaton’s 2009 Annual Report on Form 10-K. The interim period results are not necessarily indicative of the results to be expected for the full year.

ACQUISITIONS OF BUSINESSES

In 2009, Eaton acquired one business and entered into a joint venture. The Statements of Consolidated Income include the results of these businesses from the dates of the transactions. These transactions are summarized below:

	Date of	Business
Acquired business	acquisition	segment	Annual sales
Micro Innovation Holding AG A Switzerland-based manufacturer of human machine interfaces, programmable logic controllers and input/output devices. Eaton acquired the remaining shares to increase its ownership from 50% to 100%.	September 1, 2009	Electrical Rest of World	$33 for 2008
SEG Middle East Power Solutions & Switchboard Manufacture LLC A 49%-owned joint venture in Abu Dhabi that manufactures low voltage switchboards and control panel assemblies for use in the Middle East power generation and industrial markets	July 2, 2009	Electrical Rest of World	$10 for 2008

Restructuring Liabilities

For acquisitions of businesses completed prior to 2009, Eaton has undertaken restructuring activities at acquired businesses, including workforce reductions, plant consolidations, and facility closures. Liabilities for these restructuring activities were recognized in the allocation of the purchase price related to the acquired business. A summary of these liabilities, and utilization of the various components, follows:

							Plant
	Workforce reductions						closing
	Employees			Dollars			& other		Total
Balance at January 1, 2010		329		$	11		$	1	$	12
Utilized		(169	)		(4	)				(4	)
Balance at March 31, 2010		160		$	7		$	1	$	8

ACQUISITION INTEGRATION, WORKFORCE REDUCTION & PLANT CLOSING CHARGES

Acquisition Integration Charges

In 2010 and 2009, Eaton incurred charges related to the integration of acquired businesses. These charges, which consisted of plant consolidations and integration, were recognized as expense as incurred. A summary of these charges follows:

	Three months ended
	March 31
	2010		2009
Electrical Americas	$	1	$	1
Electrical Rest of World		7		16
Hydraulics				1
Aerospace		1		2
Automotive				1
Pretax charges	$	9	$	21
After-tax charges	$	6	$	14
Per common share	$	.04	$	.08

Charges in 2010 were related primarily to Moeller and Phoenixtec. Charges in 2009 were related primarily to Integrated Hydraulics, Kirloskar, Moeller, Phoenixtec and Argo-Tech.

Workforce Reduction Charges

Eaton took significant actions in 2009 to reduce its workforce in response to the severe economic downturn. The reductions total approximately 17% of the full-time workforce. These actions resulted in the recognition of severance and pension and other postretirement benefits expense of $65 in the first quarter of 2009.

Summary of Acquisition Integration, Workforce Reduction & Plant Closing Liabilities

A summary of liabilities related to acquisition integration, workforce reduction, and plant closing charges follows:

							Plant
	Workforce reductions						closing
	Employees			Dollars			& other			Total
Balance at January 1, 2010		1,418		$	43		$	12		$	55
Liabilities recognized					1			8			9
Utilized		(523	)		(14	)		(10	)		(24	)
Balance at March 31, 2010		895		$	30		$	10		$	40

These charges were included in the Statements of Consolidated Income in Cost of products sold or Selling & administrative expense, as appropriate. In Business Segment Information, the charges reduced Operating profit of the related business segment.

RETIREMENT BENEFIT PLANS EXPENSE

The components of retirement benefits expense follow:

	Three months ended March 31
							Other
							postretirement
	Pension benefits						benefits
	2010			2009			2010			2009
Service cost	$	(29	)	$	(32	)	$	(4	)	$	(4	)
Interest cost		(50	)		(49	)		(11	)		(12	)
Expected return on plan assets		54			48
Amortization		(15	)		(13	)		(3	)		(1	)
		(40	)		(46	)		(18	)		(17	)
Curtailment loss					(4	)					(1	)
Settlement loss		(5	)		(18	)
Total expense	$	(45	)	$	(68	)	$	(18	)	$	(18	)

Due to limitations imposed by the Pension Protection Act on pension lump sum distributions, Eaton’s U.S. Qualified Pension Plan became restricted in 2009 from making 100% lump sum payments. As a result, the plan experienced a significant increase in lump sum payments in 2009 before the limitation went into effect. Total pension settlement expense was $18 in the first quarter of 2009, most of which was attributable to the U.S. pension plans. A portion of the increase was attributable to the workforce reduction in 2009.

INCOME TAXES

During the first quarter of 2010, income tax expense of $31 (an effective tax rate of 16.4%) was recognized compared to an income tax benefit of $11 in the first quarter of 2009 (a tax benefit rate of 17.1%). Income tax expense for the first quarter of 2010 included a non-cash, one-time charge of $23 ($0.14 per common share) to reflect the impact of the Health Care Reform and Education Reconciliation Act on taxation associated with Medicare Part D. Without this one-time charge, income tax expense of $8 (an effective tax rate of 4%) would have been recognized in the first quarter of 2010. Income tax expense for the first quarter of 2010 also reflected a benefit associated with the successful resolution of international tax audit issues, the recognition of other international tax benefits, and a more favorable mix of geographic income. In particular, the income tax rate benefited from higher income in certain international jurisdictions. Included as an offset to the aforementioned income tax benefits that lowered the effective income tax rate in the first quarter of 2010 was an adjustment totaling $29 related to an income tax audit of transfer prices for 2005 to 2009. The Company concluded that the effect of this adjustment was not material to the prior period financial statements, as well as the projected 2010 financial statements.

MERITOR LITIGATION

On October 5, 2006, ZF Meritor LLC and Meritor Transmission Corporation (collectively, Meritor) filed an action against Eaton in the U.S. District Court for Delaware. The action seeks damages, which would be trebled under U.S. antitrust laws, as well as injunctive relief and costs. The suit alleged that Eaton engaged in anti-competitive conduct against Meritor in the sale of heavy-duty truck transmissions in North America. Following a four week trial on liability only, on October 8, 2009, the jury returned a verdict in favor of Meritor. Eaton firmly believes that it competes fairly and honestly for business in the marketplace, and that at no time did it act in an anti-competitive manner. During an earlier stage in the case, the judge concluded that damage estimates contained in a report filed by Meritor were not based on reliable data and the report was specifically excluded from the case. On November 3, 2009, Eaton filed a motion for judgment as a matter of law and to set aside the verdict. That motion is currently pending. Accordingly, an estimate of any potential loss related to this action cannot be made at this time.

NET INCOME (LOSS) PER COMMON SHARE

A summary of the calculation of net income (loss) per common share attributable to common shareholders assuming dilution and basic follows:

	Three months ended
	March 31
(Shares in millions)	2010		2009
Net income (loss) attributable to common shareholders	$	155	$	(50	)
Average number of common shares outstanding — diluted		169.6		166.1
Less dilutive effect of stock options and restricted stock awards		2.5
Average number of common shares outstanding — basic		167.1		166.1
Net income (loss) per common share — diluted	$	0.91	$	(0.30	)
Net income (loss) per common share — basic	$	0.92	$	(0.30	)

In the first quarters of 2010 and 2009, 3.6 million and 10.7 million stock options, respectively, were excluded from the calculation of diluted net income per common share because the exercise price of the options exceeded the average market price of the common shares during the period and their effect, accordingly, would have been antidilutive.

FINANCIAL ASSETS & LIABILITIES MEASURED AT FAIR VALUE

Financial instruments are categorized into a fair value hierarchy of three levels, based on the degree of subjectivity inherent in the valuation methodology as follows:

• Level 1 — Quoted prices (unadjusted) for identical assets in active markets.

• Level 2 — Quoted prices for similar assets in active markets, and inputs that are observable for the asset, either directly or indirectly, for substantially the full term of the financial instrument.

• Level 3 — Unobservable prices or inputs.

A summary of financial instruments recognized at fair value at March 31, 2010, and the fair value measurements used, follows:

9

							Recognized
	Level 1		Level 2			Level 3	value
Cash	$	151					$	151
Short-term investments		338						338
Foreign currency forward exchange contracts			$	(6	)			(6	)
Commodity contracts				6				6
Fixed-to-floating interest rate swaps				33				33
Related long-term debt converted to floating interest rates by interest rate swaps				(33	)			(33	)
Total	$	489	$	0			$	489

Level 2 financial instruments are valued using an industry standard market approach. No financial instruments were recognized using unobservable prices or inputs (Level 3).

Long-term debt and current portion of long-term debt had a carrying value of $3,352 and fair value of $3,643 at March 31, 2010.

Assets of $2,355 related to defined benefit pension plans were also measured at fair value at March 31, 2010.

DISCLOSURES ABOUT DERIVATIVE FINANCIAL INSTRUMENTS & HEDGING ACTIVITIES

In the normal course of business, Eaton is exposed to certain risks related to fluctuations in interest rates, foreign currency exchange rates and commodity prices. The Company uses various derivative and non-derivative financial instruments, primarily interest rate swaps, foreign currency forward exchange contracts, foreign currency swaps and, to a lesser extent, commodity contracts, to manage risks from these market fluctuations. The derivative financial instruments used by Eaton are straightforward, non-leveraged instruments. The counterparties to these financial instruments are financial institutions with strong credit ratings. Eaton maintains control over the size of positions entered into with any one counterparty and regularly monitors the credit rating of these institutions. Such derivative financial instruments are not purchased and sold for trading purposes.

Derivative financial instruments are measured at fair value and recognized as assets or liabilities in the Consolidated Balance Sheet. Accounting for the gain or loss resulting from the change in the fair value of the derivative financial instrument depends on whether it has been designated, and is effective, as part of a hedging relationship and, if so, on the nature of the hedging activity. Eaton formally documents all relationships between derivative financial instruments accounted for as hedges and the hedged item, as well as its risk-management objective and strategy for undertaking the hedge transaction. This process includes linking all derivative financial instruments to a recognized asset or liability, specific firm commitment, forecasted transaction, or net investment in a foreign operation. These financial instruments can be designated as:

• Hedges of the change in the fair value of a recognized fixed-rate asset or liability, or the firm commitment to acquire such an asset or liability (a fair value hedge). For these hedges, the gain or loss from the derivative financial instrument, as well as the offsetting loss or gain on the hedged item attributable to the hedged risk, are recognized in income during the period of change in fair value.

• Hedges of the variable cash flows of a recognized variable-rate asset or liability, or the forecasted acquisition of such an asset or liability (a cash flow hedge). For these hedges, the effective portion of the gain or loss from the derivative financial instrument is recognized in Eaton shareholders’ equity and reclassified to income in the same period when the gain or loss on the hedged item is included in income.

• Hedges of the foreign currency exposure related to a net investment in a foreign operation (a net investment hedge). For these hedges, the effective portion of the gain or loss from the derivative

10

financial instrument is recognized in Eaton shareholders’ equity and reclassified to income in the same period when the gain or loss related to the net investment in the foreign operation is included in income.

The gain or loss from a derivative financial instrument designated as a hedge that is effective as a hedge is included in the same line of the Statement of Consolidated Income as the offsetting loss or gain on the hedged item.

The change in fair value of a derivative financial instrument that is not effective as a hedge is immediately recognized in income.

For derivatives that are not designated as a hedge, any gain or loss is immediately recognized in income. The majority of derivatives used in this manner relate to risks resulting from assets or liabilities denominated in a foreign currency that arise in the normal course of business.

Key manufacturers in these markets and other customers are located globally, and these products are sold and serviced through a variety of channels.

The principal markets for the Aerospace segment are manufacturers of commercial and military aircraft and related after-market customers. These manufacturers and customers are located globally, and products are sold and serviced through a variety of channels.

The principal markets for the Truck and Automotive segments are original equipment manufacturers and after-market customers of heavy-, medium-, and light-duty trucks, SUVs, CUVs, or passenger cars. Customers are located globally, and most sales are made directly.

RECONCILIATION OF NON-GAAP FINANCIAL MEASURES

This Management’s Discussion & Analysis of Financial Condition & Results of Operations discloses operating earnings (loss), operating earnings (loss) per common share, and operating profit (loss) before acquisition integration charges for each business segment, each of which excludes amounts that differ from the most directly comparable measure calculated in accordance with generally accepted accounting principles (GAAP). A reconciliation of each of these financial measures to the most directly comparable GAAP measure is included in the Summary of Results for 2010 and in Results by Business Segment. Management’s Discussion & Analysis of Financial Condition & Results of Operations also discloses net income and net income per common share, and operating earnings and operating earnings per common share, before the non-cash, one-time income tax charge of $23 ($.14 per share) related to Medicare Part D, discussed below. Management believes that these financial measures are useful to investors because they exclude transactions of an unusual nature, allowing investors to more easily compare Eaton’s financial performance period to period. Management uses this information in monitoring and evaluating the on-going performance of Eaton and each business segment.

SUMMARY OF RESULTS OF OPERATIONS FOR 2010 COMPARED TO 2009

Eaton reported net sales of $3.1 billion in the first quarter of 2010, an increase of 10% over the first quarter of 2009. Net income of $155 in the first quarter of 2010 increased $205 over the first quarter of 2009 when a net loss of ($50) was recognized. Net income per common share was $0.91 in the first quarter of 2010

14

compared to a net loss per share of $(0.30) in the first quarter of 2009. The expanding world economy drove growth in most end markets and the Company’s newly-reset cost structure allowed Eaton to realize strong incremental margins on the increase in sales. Net income included a non-cash, one-time income tax charge of $23 ($0.14 per common share) related to Medicare Part D resulting from the new Health Care Reform and Education Reconciliation Act. Adjusting for this one-time income tax charge, net income was $178, and net income per share was $1.05, in the first quarter of 2010, compared to a net loss of $(50), and a net loss per share of ($0.30), in the first quarter of 2009.

The following are highlights of results for 2010 compared to 2009:

	Three months ended March 31
							Increase			Percentage

Operating earnings (loss) per common share	$	0.95		$	(0.22	)	$	1.17

Net sales in the first quarter of 2010 increased by 10% compared to the first quarter of 2009. The increase included 5% from core sales and 5% from foreign exchange. Eaton’s end markets grew 4% in the first quarter of 2010 compared to the first quarter of 2009. The expanding world economy drove growth in most end markets and the Company’s newly-reset cost structure allowed the Company to realize strong incremental margins on the increase in sales.

Gross profit increased by 41% in the first quarter of 2010 compared to the first quarter of 2009. The increase was primarily due to the increase in net sales discussed above and savings associated with workforce reductions taken in 2009. The improvement in 2010 also reflected pretax charges of $65 for severance and pension and other postretirement benefits expense in the first quarter of 2009 resulting from the workforce reductions taken in 2009.

In the first quarter of 2010, Eaton reported net income of $155 and net income per common share of $0.91, compared to a net loss of $(50) in the first quarter of 2009 and a net loss per share of $(0.30). The increases were primarily due to higher net sales in 2010 and the factors that affected gross profit discussed above. Adjusting for the non-cash, one-time income tax charge of $23 ($0.14 per share) related to Medicare Part D resulting from the new U.S. health care law, net income in 2010 was $178, or $1.05 per share. Before the effect of acquisition integration charges, operating earnings were $161 in the first quarter 2010, or $0.95 per

15

share, compared to an operating loss of $(36) in the first quarter of 2009, or $(0.22) per share. Adjusting for the non-cash, one-time income tax charge related to Medicare Part D, operating earnings in 2010 were $184, or $1.09 per share.

Net cash used by operating activities was $(162) in the first quarter of 2010, a decrease of $257 compared to net cash provided by operations of $95 in the first quarter of 2009. Operating cash flows in 2010 reflected higher net income in the first quarter of 2010 of $156, before the adjustment for noncontrolling interests, compared to a loss of $(52) in the first quarter of 2009. Cash provided by operating activities in the first quarter of 2010 was lowered by $326 of cash contributed to pension plans, compared to $61 in the first quarter of 2009, and a use of cash of $212 resulting from an increase in funding of working capital in the first quarter of 2010 compared to a decrease in working capital in the first quarter of 2009. The increase in working capital funding, primarily accounts receivable and inventory, was due to higher levels of operations resulting from the global economic recovery. Cash and short-term investments totaled $489 at March 31, 2010, a decrease of $284 from $773 at December 31, 2009.

Total debt of $3,442 at March 31, 2010 declined by $25 from $3,467 at December 31, 2009. The decline was primarily due to a $23 reduction of short-term debt during 2010. Short-term debt was reduced through the use of cash generated from operations. The net-debt-to-capital ratio was 30.6% at March 31, 2010 compared to 28.4% at the end of 2009, reflecting the combined effect of the $25 decrease in total debt, the $284 decrease in cash and short-term investments, and the $94 decrease in Eaton shareholders’ equity. The decrease in equity primarily resulted from foreign currency translation adjustments of $176 and cash dividends paid of $84, partially offset by net income of $155.

Net working capital of $1,710 at March 31, 2010 declined by $125 from $1,835 at the end of 2009. The decline was primarily due to the reduction of cash and short-term investments to fund increases in accounts receivable and inventory due to higher levels of operations resulting from the global economic recovery. The current ratio was 1.6 at March 31, 2010 compared to 1.7 at year-end 2009.

As of mid-April 2010, Eaton anticipates its end markets will grow 6% for all of 2010. In general, the Company is seeing the strongest growth in Asia Pacific and Brazil, while many U.S. markets are starting to accelerate and Europe is recovering more modestly.

OTHER RESULTS OF OPERATIONS

Eaton took significant actions in 2009 to reduce its workforce in response to the severe economic downturn. The reductions total approximately 17% of the full-time workforce. These actions resulted in the recognition of severance and pension and other postretirement benefits expense of $65 in the first quarter of 2009. These charges were included in the Statements of Consolidated Income in Cost of products sold or Selling & administrative expense, as appropriate. In Business Segment Information, the charges reduced Operating profit of the related business segment.

In 2010 and 2009, Eaton incurred charges related to the integration of acquired businesses. These charges, which consisted of plant consolidations and integration, were recognized as expense as incurred. A summary of these charges follows:

	Three months ended
	March 31
	2010		2009
Electrical Americas	$	1	$	1
Electrical Rest of World		7		16
Hydraulics				1
Aerospace		1		2
Automotive				1
Pretax charges	$	9	$	21
After-tax charges	$	6	$	14
Per common share	$	.04	$	.08

16

Charges in 2010 were related primarily to Moeller and Phoenixtec. Charges in 2009 were related primarily to Integrated Hydraulics, Kirloskar, Moeller, Phoenixtec and Argo-Tech. The acquisition integration charges were included in the Statements of Consolidated Income in Cost of products sold or Selling & administrative expense, as appropriate. In Business Segment Information, the charges reduced Operating profit of the related business segment.

During the first quarter of 2010, income tax expense of $31 (an effective tax rate of 16.4%) was recognized compared to an income tax benefit of $11 in the first quarter of 2009 (a tax benefit rate of 17.1%). Income tax expense for the first quarter of 2010 included a non-cash, one-time charge of $23 ($0.14 per common share) to reflect the impact of the Health Care Reform and Education Reconciliation Act on taxation associated with Medicare Part D. Without this one-time charge, income tax expense of $8 (an effective tax rate of 4%) would have been recognized in the first quarter of 2010. Income tax expense for the first quarter of 2010 also reflected a benefit associated with the successful resolution of international tax audit issues, the recognition of other international tax benefits, and a more favorable mix of geographic income. In particular, the income tax rate benefited from higher income in certain international jurisdictions. Included as an offset to the aforementioned income tax benefits that lowered the effective income tax rate in the first quarter of 2010 was an adjustment totaling $29 related to an income tax audit of transfer prices for 2005 to 2009.

RESULTS BY BUSINESS SEGMENT

Electrical Americas

	Three months ended March 31
	2010			2009			(Decrease)
Net sales	$	802		$	859			(7	)%
Operating profit		105			106			(1	)%
Operating margin		13.1	%		12.3	%
Acquisition integration charges	$	1		$	1
Before acquisition integration charges
Operating profit		106			107			(1	)%
Operating margin		13.2	%		12.5	%

Sales of the Electrical Americas segment decreased 7% in the first quarter of 2010 compared to the first quarter of 2009. The decrease consisted of 9% in core sales partially offset by a 2% increase from foreign exchange. The decline in sales reflected end markets for this segment that were down 8% in 2010 compared to the first quarter of 2009. Late cycle non-residential end markets declined about 21% in 2010, partially offset by growth in the early cycle power quality, residential, and industrial controls businesses. For all of 2010, Eaton anticipates end markets for this segment will decline by 3%.

Operating profit in the first quarter of 2010 was $105. Excluding acquisition integration charges of $1 in 2010, operating profit was $106. The decrease in operating profit before acquisition integration charges in 2010 from the first quarter of 2009 was largely due to the 7% decrease in sales in 2010 discussed above, partially offset by savings resulting from the workforce reductions taken in 2009.

In April 2010, Eaton won a contract to provide the U.S. Air Force’s Air Logistics Center with power reliability products and turnkey services. Over the five year life of the contract, revenues totaling up to $569 will be split between Eaton and one other supplier.

Sales of the Electrical Rest of World segment increased 12% in the first quarter of 2010 compared to the first quarter of 2009. The increase included 4% from core sales and 8% from foreign exchange. Sales in 2010 reflected accelerating strength in end markets, particularly in Asia Pacific. For all of 2010, Eaton anticipates end markets for this segment will grow by 6%.

Operating profit in the first quarter of 2010 was $42. Excluding acquisition integration charges of $7 in 2010, operating profit was $49. The increase in operating profit before acquisition integration charges in 2010 from the first quarter of 2009 was largely due to the increase in sales in 2010 described above and savings resulting from the workforce reductions taken in 2009.

Hydraulics

	Three months ended March 31
	2010			2009			Increase
Net sales	$	490		$	430			14	%

Operating margin		11.0	%		1.6	%

Sales of the Hydraulics segment increased 14% in the first quarter of 2010 compared to the first quarter of 2009. The increase included 11% from core sales and 3% from foreign exchange. Global hydraulics markets increased 1% in 2010 compared to the first quarter of 2009, but grew 7% over the fourth quarter of 2009. For all of 2010, Eaton now believes hydraulics markets are likely to grow by 16%.

Operating profit in the first quarter of 2010 was $54. The increase in operating profit before acquisition integration charges in 2010 compared to the first quarter of 2009 was primarily due to the increase in sales in 2010 discussed above and savings resulting from the workforce reductions taken in 2009.

Aerospace

	Three months ended March 31
	2010			2009			(Decrease)
Net sales	$	376		$	418			(10	)%
Operating profit		49			71			(31	)%
Operating margin		13.0	%		17.0	%
Acquisition integration charges	$	1		$	2
Before acquisition integration charges
Operating profit		50			73			(32	)%
Operating margin		13.3	%		17.5	%

Sales of the Aerospace segment decreased 10% in the first quarter of 2010 compared to the first quarter of 2009. The decrease included 12% from core sales partially offset by an increase of 2% from foreign exchange. Aerospace end markets declined 5% in 2010 compared to the first quarter of 2009. Eaton

18

anticipates global aerospace markets will decline 1% for all of 2010 versus the prior estimate of a 3% decline.

Operating profit in the first quarter of 2010 was $49. Excluding acquisition integration charges of $1 in 2010, operating profit was $50. The decrease in operating profit before acquisition integration charges in 2010 from the first quarter of 2009 was primarily due to the decline in sales in 2010 discussed above.

Truck

	Three months ended March 31
	2010			2009			Increase
Net sales	$	453		$	292			55	%
Operating profit (loss)		46			(34	)	NM
Operating margin		10.2	%		(11.6	)%

Sales of the Truck segment increased 55% in the first quarter of 2010 compared to the first quarter of 2009. The increase included 44% from core sales and 11% from foreign exchange. Global end markets in 2010 increased by 19% over the first quarter of 2009. For all of 2010, Eaton anticipates end markets for this segment will grow by 17%.

Operating profit in the first quarter of 2010 was $46. The increase in operating profit in 2010 from the first quarter of 2009 was primarily due to the increase in sales in 2010 discussed above and the savings resulting from the workforce reductions taken in 2009.

Automotive

	Three months ended March 31
	2010			2009			Increase
Net sales	$	374		$	270			39	%

Global automotive markets were up 46% in 2010 compared to the first quarter of 2009. For all of 2010, Eaton anticipates global automotive markets will grow by 15%, with U.S. production up 31% and non-U.S. production up 6%.

Operating profit in the first quarter of 2010 was $42. The increase in operating profit before acquisition integration charges in 2010 from the first quarter of 2009 was primarily due to the increase in sales in 2010 discussed above and the savings resulting from the workforce reductions taken in 2009.

Corporate

Corporate pension & other postretirement benefit expense of $32 in the first quarter of 2010 declined from $47 in the first quarter of 2009. The decline was primarily due to reduced pension curtailment and settlement losses recognized in 2010 compared to 2009, and charges related to the workforce reduction in 2009.

CHANGES IN FINANCIAL CONDITION DURING 2010

Cash flow and working capital

Net cash used by operating activities was $(162) in the first quarter of 2010, a decrease of $257 compared to net cash provided by operations of $95 in the first quarter of 2009. Operating cash flows in 2010 reflected higher net income in the first quarter of 2010 of $156, before the adjustment for noncontrolling interests, compared to a loss of $(52) in the first quarter of 2009. Cash provided by operating activities in the first quarter of 2010 was lowered by $326 of cash contributed to pension plans, compared to $61 in the first quarter of 2009, and a use of cash of $212 resulting from the net increase in funding of working capital in the first quarter of 2010 compared to a decrease in working capital in the first quarter of 2009. The increase in working capital funding, primarily accounts receivable and inventory, was due to higher levels of operations

19

resulting from the global economic recovery. Cash and short-term investments totaled $489 at March 31, 2010, a decrease of $284 from $773 at December 31, 2009.

Net working capital of $1,710 at March 31, 2010 declined by $125 from $1,835 at the end of 2009. The decline was primarily due to the reduction of cash and short-term investments to fund increases in accounts receivable and inventory due to higher levels of operations resulting from the global economic recovery. The current ratio was 1.6 at March 31, 2010 compared to 1.7 at year-end 2009.

Debt

Total debt of $3,442 at March 31, 2010 declined by $25 from $3,467 at December 31, 2009. The decline was primarily due to a $23 reduction of short-term debt during 2010. Short-term debt was reduced through the use of cash generated from operations. The net-debt-to-capital ratio was 30.6% at March 31, 2010 compared to 28.4% at the end of 2009, reflecting the combined effect of the $25 decrease in total debt, the $284 decrease in cash and short-term investments, and the $94 decrease in Eaton shareholders’ equity. The decrease in equity primarily resulted from foreign currency translation adjustments of $176 and cash dividends paid of $84, partially offset by net income of $155.
