NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Dollars in thousands, except per share amounts

In the opinion of the management of the Company, the accompanying unaudited consolidated financial statements contain all adjustments (consisting of only normal recurring accruals) necessary to present fairly the financial position as of March 31, 2009, the results of operations for the three and nine months ended March 31, 2009 and 2008 and cash flows for the nine months then ended. These financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company’s 2008 Annual Report on Form 10-K. Interim period results are not necessarily indicative of the results to be expected for the full fiscal year.

In March 2008, the Financial Accounting Standards Board (FASB) issued FASB Statement No. 161, “Disclosures about Derivative Instruments and Hedging Activities.” Statement No. 161 establishes guidelines to report how derivative and hedging activities affect an entity’s financial position, financial performance, and cash flows. The Company adopted the provisions of Statement No. 161 during the quarter ended March 31, 2009.

In December 2007, the FASB issued FASB Statement No. 141 (revised 2007), “Business Combinations” (Statement No. 141R). Statement No. 141R changes the accounting for business combinations both during the period of acquisition and in subsequent periods. Acquisition costs will generally be expensed as incurred; noncontrolling interests will be valued at fair value at the acquisition date; in-process research and development will be recorded at fair value as an indefinite-lived asset at the acquisition date; restructuring costs associated with a business combination will generally be expensed subsequent to the acquisition date; and changes in deferred tax asset valuation allowances and income tax uncertainties after the acquisition date generally will affect income tax expense. Statement No. 141R is effective for fiscal years beginning after December 15, 2008. Generally, the effect of Statement No. 141R on the Company’s financial position or results of operations will depend on future acquisitions.

In December 2007, the FASB issued FASB Statement No. 160, “Noncontrolling Interests in Consolidated Financial Statements – an amendment of ARB 51.” Statement No. 160 requires the recognition of a noncontrolling interest as equity in the consolidated financial statements and separate from the parent’s equity. The amount of net income attributable to the noncontrolling interest will be included in consolidated net income on the face of the income statement. Statement No. 160 is effective for fiscal years beginning after December 15, 2008. The Company has not yet determined the effect on the Company’s financial position or results of operations of complying with the provisions of Statement No. 160.

In December 2008, the FASB issued FASB Staff Position (FSP) 132(R)-1, “Employers’ Disclosures about Postretirement Benefit Plan Assets.” FSP 132(R)-1 requires detailed disclosures regarding the investment strategies, fair value measurements, and concentrations of risk of plan assets of a defined benefit pension or other postretirement plan. FSP 132(R)-1 is effective for fiscal years ending after December 15, 2009. The Company has not yet determined the effect, if any, that FSP 132(R)-1 will have on the Company’s retirement benefits disclosures.

In the ordinary course of business, the Company warrants its products against defect in design, materials and workmanship over various time periods. The warranty accrual as of March 31, 2009 and June 30, 2008 is immaterial to the financial position of the Company and the change in the accrual for the current quarter and first nine months of fiscal 2009 is immaterial to the Company’s results of operations and cash flows.

The following table presents a reconciliation of the numerator and denominator of basic and diluted earnings per share for the three and nine months ended March 31, 2009 and 2008.

For the three months ended March 31, 2009 and 2008, 10,639,997 and 868,301 common shares subject to equity-based awards, respectively, were excluded from the computation of diluted earnings per share because the effect of their exercise would be anti-dilutive. For the nine months ended March 31, 2009 and 2008, 5,830,350 and 1,444,043 common shares subject to equity-based awards, respectively, were excluded from the computation of diluted earnings per share because the effect of their exercise would be anti-dilutive.

The Company has a program to repurchase its common shares. Under the program, the Company is authorized to repurchase an amount of common shares each fiscal year equal to the greater of 7.5 million shares or five percent of the shares outstanding as of the end of the prior fiscal year. Repurchases are funded primarily from operating cash flows, and the shares are initially held as treasury stock. During the three-month period ended March 31, 2009, the Company repurchased 217,900 shares of its common stock at an average price of $40.57 per share. Fiscal year-to-date, the Company repurchased 7,438,624 shares of its common stock at an average price of $59.53 per share.

The Company’s primary item of other comprehensive income is foreign currency translation adjustments. Comprehensive income for the three and nine months ended March 31, 2009 and 2008 was as follows:

During the third quarter of fiscal 2009, the Company recorded a $25,206 charge for the costs to structure its businesses in light of current and anticipated customer demand. The Company believes the realignment actions will positively impact future results of operations but will have no material effect on liquidity and sources and uses of capital. The charge primarily consists of severance costs and is presented primarily in the Cost of sales caption in the Consolidated Statement of Income for the three months ended March 31, 2009.

During the first nine months of fiscal 2009, the Company recorded a charge of $36,939 for business realignment costs. The Company believes the realignment actions will positively impact future results of operations but will have no material effect on liquidity and sources and uses of capital. The charge primarily consists of severance costs and is presented primarily in the Cost of sales caption in the Consolidated Statement of Income for the nine months ended March 31, 2009.

- 8 -

During the third quarter of fiscal 2008, the Company recorded a $1,099 charge for the costs to structure its businesses in light of current and anticipated customer demand. The Company believes the realignment actions will positively impact future results of operations but will have no material effect on liquidity and sources and uses of capital. The charge primarily consisted of severance costs and costs to relocate machinery and equipment. The business realignment costs are presented in the Cost of sales caption in the Consolidated Statement of Income for the three months ended March 31, 2008.

During the first nine months of fiscal 2008, the Company recorded a charge of $5,104 for business realignment costs. The Company believes the realignment actions will positively impact future results of operations but will have no material effect on liquidity and sources and uses of capital. The charge primarily consisted of severance costs and costs to relocate machinery and equipment. The business realignment costs are presented primarily in the Cost of sales caption in the Consolidated Statement of Income for the nine months ended March 31, 2008.

The Company has completed its annual goodwill impairment test required by FASB Statement No. 142. Goodwill is tested for impairment at the reporting unit level, which for the Company, is one level below the operating segment level. The Company conducted step 1 of the goodwill impairment test for approximately 90 reporting units as of December 31, 2008. The Company used a discounted cash flow model to determine the fair value of a reporting unit. The discounted cash flow analysis requires several assumptions including future sales growth and operating margin levels. Each of the Company’s reporting units prepare discrete operating forecasts and used these forecasts as the basis for the assumptions used in the discounted cash flow analyses. The Company used a discount rate commensurate with its current cost of capital, adjusted for inherent business risks and used a terminal growth factor of 2.5 percent. The results of step 1 indicate that no goodwill impairment exists as the fair value of each reporting unit tested exceeded its carrying value. Additionally, the Company reconciled the estimated aggregate fair value of its reporting units as derived from the discounted cash flow analyses to the Company’s overall market capitalization.

The Company will continue to monitor for impairment indicators at each of its reporting units and will update assumptions used in the estimation of the reporting units fair value as appropriate.

The changes in the carrying amount of goodwill for the nine months ended March 31, 2009 are as follows:

“Goodwill adjustments” primarily represent final adjustments to the purchase price allocation during the twelve-month period subsequent to the acquisition date and generally involves the valuation of property, plant and equipment and intangible assets. The fiscal 2009 purchase price allocations are preliminary and may require subsequent adjustment.

Intangible assets are amortized on the straight-line method over their legal or estimated useful lives. The following summarizes the gross carrying value and accumulated amortization for each major category of intangible assets:

Total intangible amortization expense for the nine months ended March 31, 2009 was $73,781. The estimated amortization expense for the five years ending June 30, 2009 through 2013 is $98,575, $105,406, $99,991, $89,280 and $81,849, respectively.

Net periodic pension cost recognized included the following components:

- 10 -

Postretirement benefit cost recognized included the following components:

Historically, the Company has provided self-insured retiree medical plan benefits for non-union employees upon their retirement. The retiree was responsible for paying the premiums for the medical coverage but the Company paid the costs of administering the plans (i.e., claims processing costs). Absorbing the administration costs was considered a benefit under FASB Statement No. 106 as the employees who elected to enroll in the retiree medical plans paid a lower premium since the Company was paying the costs to administer the plan. In the third quarter of fiscal 2009, the Company discontinued its self-insured retiree medical plans for non-union employees and has therefore eliminated the cost associated with administering the plans. The Company recognized $22.4 million in income in the third quarter of fiscal 2009 as a result of eliminating the liability related to this benefit.

As of March 31, 2009, the Company had gross unrecognized tax benefits of $114,806. The total amount of gross unrecognized tax benefits that, if recognized, would affect the effective tax rate was $83,106. The accrued interest related to the gross unrecognized tax benefits, excluded from the amounts above, was $10,187.

The Company and its subsidiaries file income tax returns in the U.S. and various state and foreign jurisdictions. In the normal course of business, the Company is subject to examination by tax authorities throughout the world. The Company is no longer subject to examinations of its federal income tax returns by the Internal Revenue Service (IRS) for fiscal years through 2001, except for certain refund claims outstanding. All significant state and local and foreign tax returns have been examined for fiscal years through 2001. The Company believes that it is reasonably possible that within the next 12 months the IRS examination for fiscal years 2002 and 2005 will be settled. The Company anticipates that within the next 12 months the total amount of unrecognized tax benefits related to income inclusion items may be reduced by an amount up to $25 million due to the settlement of examinations and the expiration of statutes of limitation.

On July 1, 2008, the Company adopted the provisions of FASB Statement No. 157, “Fair Value Measurements.” Statement No. 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. Statement No. 157 indicates that, among other things, a fair value measurement assumes that the transaction to sell an asset or transfer a liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. FASB Staff Position 157-2 delays the effective date of the application of Statement No. 157 to fiscal years beginning after November 15, 2008 for all nonfinancial assets and nonfinancial liabilities that are recognized or disclosed at fair value in the financial statements on a nonrecurring basis. The adoption of Statement No. 157 had no effect on the Company’s financial position or results of operations.

- 11 -

A summary of financial assets and liabilities that were measured at fair value on a recurring basis at March 31, 2009 follows:

Available for sale securities are measured at fair value using quoted market prices. The fair value of derivatives is calculated through a model that utilizes market observable inputs including both spot and forward prices for the same underlying currencies.

The Company has established nonqualified deferred compensation programs which permit officers, directors and certain management employees to defer a portion of their compensation, on a pre-tax basis, until their termination of employment. Changes in the value of the compensation deferred under these programs are recognized based on the fair value of the participants accounts based on their investment elections.

On July 1, 2008, the Company adopted the provisions of FASB Statement No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities.” Statement No. 159 permits entities to choose to measure many financial instruments and certain other items at fair value. The Company did not elect to measure any financial assets or financial liabilities at fair value that were otherwise not required to be measured at fair value under other accounting standards.

During the first nine months of fiscal 2009, the Company completed nine acquisitions including the acquisitions of Legris SA and Origa Group. Legris SA is a manufacturer of fluid circuit components and systems for pneumatic, hydraulic, and chemical processing applications. Origa Group is a manufacturer of rodless pneumatic actuators, electric actuators, filter regulator lubricators, pneumatic cylinders and valves used in the transportation, semiconductor and packaging and conveying markets. Aggregate annual revenues for the nine acquisitions completed during the first nine months of fiscal 2009, for their most recent fiscal year prior to acquisition, were approximately $532 million. The results of operations for all acquisitions are included as of the respective dates of acquisition. The Company primarily used cash on hand and proceeds from commercial paper borrowings to fund the acquisitions.

The Company is involved in various litigation arising in the normal course of business, including proceedings based on product liability claims, workers’ compensation claims and alleged violations of various environmental laws. The Company is self-insured in the United States for health care, workers’ compensation, general liability and product liability up to predetermined amounts, above which, subject to certain limitations, third party insurance applies. Management regularly reviews the probable outcome of these proceedings, the expenses expected to be incurred, the availability and limits of the insurance coverage, and the established accruals for liabilities. While the outcome of pending proceedings cannot be predicted with certainty, management believes that any liabilities that may result from these proceedings will not have a material adverse effect on the Company’s liquidity, financial condition or results of operations.

Parker ITR S.r.l. (Parker ITR), a subsidiary acquired on January 31, 2002, has been the subject of a number of lawsuits and regulatory investigations since April 27, 2007, when a grand jury in the Southern District of Florida issued a subpoena to Parker ITR and the Company requiring the production of documents, in particular, documents related to communications with competitors and customers related to Parker ITR’s business unit that manufactures marine hose, typically used in oil transfer. The lawsuits and investigations relate to allegations that for a period of up to 21 years, the Parker ITR business unit that manufacturers and sells marine hose conspired with competitors in unreasonable restraint of trade to artificially raise, fix, maintain or stabilize prices, rig bids and allocate markets and customers for marine oil and gas hose in the United States and in other jurisdictions.

On May 15, 2007, the European Commission issued its initial Request for Information to the Company and Parker ITR. On August 2, 2007, the Japan Fair Trade Commission (JFTC) requested that Parker ITR submit a report to the JFTC on specific topics related to its investigation of marine hose suppliers. Brazilian competition authorities and Korean competition authorities commenced their investigations on November 14, 2007 and January 17, 2008, respectively. Parker ITR and the Company have cooperated with all of the regulatory authorities investigating the activities of the Parker ITR business unit that manufactures and sells marine hose and continue to cooperate with the investigations that remain ongoing.

In addition, during this time period, four class action lawsuits were filed in the Southern District of Florida: Shipyard Supply LLC v. Bridgestone Corporation, et al., filed May 17, 2007; Expro Gulf Limited v. Bridgestone Corporation, et al., filed June 6, 2007; Bayside Rubber & Products, Inc. v. Trelleborg Industrie S.A., et al., filed June 25, 2007; Bayside Rubber & Products, Inc. v. Caleca, et al., filed July 12, 2007; and one in the Southern District of New York: Weeks Marine, Inc. v. Bridgestone Corporation, et al., filed July 27, 2007. On September 12, 2008, the plaintiffs filed an amended consolidated class action complaint. Plaintiffs have since filed another amended consolidated complaint naming prior owners of the Parker ITR business unit that manufactures and sells marine hose. Plaintiffs generally seek treble damages, a permanent injunction, attorneys’ fees, and pre-judgment and post-judgment interest.

The time period for the alleged illegal activities by Parker ITR’s marine hose business unit varies by jurisdiction. In the United States, the Department of Justice, which initiated the April 2007 grand jury subpoenas, alleges that the challenged activities commenced in the United States in 1999 and ended May 2, 2007. The Department of Justice’s investigation is ongoing and the Company and Parker ITR continue to cooperate.

In Brazil, Parker ITR filed a procedural defense in January 2008. The Brazilian competition authorities have not yet responded to Parker ITR’s filing. The Brazilian competition authorities’ investigation is ongoing and the Company and Parker ITR continue to cooperate. The Brazilian authorities appear to be investigating the period 1999 through May 2007. Because the Brazilian competition authorities have not yet responded to Parker ITR’s initial filing, the potential outcome of this investigation is uncertain and will depend on the resolution of numerous issues not yet addressed at the current preliminary stage of the investigation.

- 13 -

In Korea, the Korean Fair Trade Commission (KFTC) submitted several questionnaires to Parker ITR in connection with their investigation of Parker ITR’s marine hose bidding activities in Korea from 1999 to May 2, 2007. Parker ITR responded to each questionnaire and continues to cooperate with the KFTC. The KFTC has issued an examiner’s report, but it is unclear as to the amount of any fine that may be imposed on Parker ITR.

The JTFC completed its investigation and issued an administrative order requiring Parker ITR to take certain actions, including passing a board resolution that prohibited the challenged conduct in the future and to send letters to Parker ITR’s customers and competitors in Japan stating that Parker ITR would not engage in the challenged conduct in Japan in the future. Parker ITR has complied with the JFTC administrative order.

On January 28, 2009, the European Commission announced the results of its investigation of the alleged cartel activities. As part of its decision, the European Commission found that Parker ITR infringed Article 81 of the European Commission treaty from April 1986 to May 2, 2007 and fined Parker ITR 25.61 million euros. The European Commission also determined that the Company was jointly and severally responsible for 8.32 million euros of the total fine which related to the period from January 2002, when the Company acquired Parker ITR, to May 2, 2007, when the cartel activities ceased. Parker ITR and the Company filed an appeal to the Court of First Instance of the European Communities on April 10, 2009.

The Company and Parker ITR have reached a settlement of the class action litigation in the United States, which is subject to court approval. On February 17, 2009, Parker ITR entered into a separate agreement to settle possible private causes of action outside the United States.

As of March 31, 2009, the Company has a reserve of $36.9 million for known and potential losses. Legal expenses related to these matters are being expensed as incurred.

FORM 10-Q

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

FOR THE THREE AND NINE MONTHS ENDED MARCH 31, 2009

AND COMPARABLE PERIODS ENDED MARCH 31, 2008

OVERVIEW

The Company is a leading worldwide diversified manufacturer of motion control technologies and systems, providing precision engineered solutions for a wide variety of mobile, industrial and aerospace markets.

The Company’s order rates provide a near-term perspective of the Company’s outlook particularly when viewed in the context of prior and future order rates. The Company publishes its order rates on a quarterly basis. The lead time between the time an order is received and revenue is realized generally ranges from one day to 12 weeks for mobile and industrial orders and from one day to 18 months for aerospace orders. The Company believes the leading economic indicators that have a strong correlation to the Company’s future order rates are as follows:

ISM and PMI indexes above 50 indicate that the manufacturing economy is expanding resulting in the expectation that the Company’s order rates in the mobile and industrial markets in the respective geographic areas should be positive year-over-year. ISM and PMI indexes below 50 would indicate the opposite effect. The ISM index at the end of March 2009 was 36.3 and the most recent PMI for the Eurozone countries was 33.9. The ISM index and the PMI index for the Eurozone countries have both decreased significantly during the first nine months of fiscal 2009 and the Company’s order rates during this same time period have reflected this decline. At this time, the Company is unable to determine if the downward trend in order rates will continue and if so, for how long and at what rate of decline. With respect to the aerospace market, aircraft miles flown and revenue passenger miles during fiscal 2009 have declined moderately from comparable fiscal 2008 levels. The Company anticipates that Department of Defense spending in fiscal 2009 will be about 4 percent higher than the 2008 level. Housing starts in March 2009 were approximately 48 percent lower than housing starts in March 2008. The Company does not anticipate housing starts to improve in the foreseeable future.

The Company also believes that there is a high correlation between changes in interest rates throughout the world and worldwide industrial manufacturing activity. Increases in interest rates typically have a negative impact on industrial production thereby lowering future order rates while decreases in interest rates typically have the opposite effect. However, recent interest rate cuts have not had the same impact on worldwide industrial manufacturing activity as past interest rate cuts.

The Company remains focused on maintaining its financial strength through the current worldwide economic downturn by adjusting its cost structure to reflect changing demand levels, maintaining a strong balance sheet and managing its cash. The Company’s WIN Strategy initiatives relating to growth and margin improvement are well designed to assist in meeting this challenge. The Company

- 15 -

has implemented several additional initiatives, including workforce reductions, salary freezes, and short work weeks, to reduce costs in response to the continued deterioration in worldwide economic conditions and the corresponding decline in the Company’s order rates. The Company has also developed contingency plans to further control costs if economic conditions continue to deteriorate.

Despite the current economic conditions, the financial condition of the Company remains strong. The Company continues to generate substantial cash flows from operations, has proactively managed working capital and controlled capital spending, currently has a debt to debt-equity ratio of 36.8 percent and has been able to borrow needed funds at affordable interest rates.

While current worldwide economic conditions necessitate that the Company concentrate its efforts on maintaining its financial strength, the Company believes many opportunities for growth remain available. The Company will pursue these opportunities as appropriate in the current environment in order to strongly position itself for when the economic recovery ultimately occurs. Major opportunities for growth are as follows:

During the first nine months of fiscal 2009, the Company completed nine acquisitions whose aggregate incremental annual revenues were approximately $532 million. Acquisitions will continue to be considered from time to time to the extent there is a strong strategic fit, while at the same time, maintaining the Company’s strong financial position. The Company will also continue to assess the strategic fit of its existing businesses and initiate efforts to divest businesses that are not considered to be a good long-term fit for the Company. Future business divestitures could have a negative effect on the Company’s results of operations.

The discussion below is structured to separately discuss the Consolidated Statement of Income, Results by Business Segment, Balance Sheet and Statement of Cash Flows.

CONSOLIDATED STATEMENT OF INCOME

- 16 -

Net sales for the current-year quarter and first nine months of fiscal 2009 decreased 26.3 percent and 8.0 percent, respectively, over the comparable prior-year net sales amounts reflecting lower volume in all segments except for the Aerospace Segment. Acquisitions made in the last 12 months contributed approximately $146 million and $450 million in sales in the current-year quarter and first nine months of fiscal 2009, respectively. The effect of currency rate changes decreased net sales by approximately $218 million and $338 million in the current-year quarter and first nine months of fiscal 2009, respectively.

Gross profit margin decreased in the current-year quarter and first nine months of fiscal 2009 primarily due to a combination of the lower sales volume, resulting in manufacturing inefficiencies, and unfavorable product mix. Also included in gross profit are business realignment charges of $18.3 million and $1.1 million in the current-year quarter and prior-year quarter, respectively, and $28.8 million and $5.0 million for the first nine months of fiscal 2009 and 2008, respectively.

Selling, general and administrative expenses decreased for the current-year quarter and first nine months of fiscal 2009 primarily due to the lower sales volume and lower incentive compensation partially offset by current-year acquisitions.

Interest expense for the current-year quarter and first nine months of fiscal 2009 increased primarily due to higher average debt outstanding in the current-year quarter and first nine months of fiscal 2009. The increase in borrowings primarily related to the funding of current-year acquisitions and the repurchase of the Company’s common shares.

Other expense (income), net in the current-year quarter included $36.2 million of expense related to litigation settlements and $11.6 million of income related to insurance recoveries. Other expense (income), net for the first nine months of fiscal 2009 included $37.4 million of expense related to litigation settlements, $7.7 million of expense related to an investment and $11.6 million of income related to insurance recoveries.

Effective tax rate for the current-year quarter and first nine months of fiscal 2009 was lower primarily due to a tax benefit associated with a worthless stock deduction related to the Parker ITR S.r.l. subsidiary as well as lower taxable income.

RESULTS BY BUSINESS SEGMENT

Industrial Segment

- 17 -

The Industrial Segment operations experienced the following percentage changes in net sales in the current-year period compared to the equivalent prior-year period:

The above presentation reconciles the percentage changes in net sales of the Industrial operations reported in accordance with U.S. GAAP to percentage changes in net sales adjusted to remove the effects of acquisitions made within the prior four fiscal quarters as well as the effects of currency exchange rates. The effects of acquisitions and currency exchange rates are removed to allow investors and the Company to meaningfully evaluate the percentage changes in net sales on a comparable basis from period to period.

Excluding the effects of acquisitions and foreign currency changes, the decrease in Industrial North American sales for the current-year quarter and first nine months of fiscal 2009 reflects lower demand experienced from distributors and lower end-user demand experienced in virtually all of the markets of the Industrial North American businesses as customers have reduced order levels in response to current economic conditions. The decrease in Industrial International sales for the current-year quarter and first nine months of fiscal 2009 is primarily attributable to lower volume across most markets in all regions with the largest decline in volume experienced in Europe.

Margins in the Industrial North American businesses and Industrial International businesses were lower for the current-year quarter and first nine months of fiscal 2009 due primarily to the lower sales volume, resulting in manufacturing inefficiencies, and higher expenses associated with business realignment activities. Current-year acquisitions, not yet fully integrated, also negatively impacted both Industrial North American and Industrial International margins in the current-year quarter and first nine months of fiscal 2009.

Included in Industrial North American operating income are business realignment charges of $6.0 million and $8.6 million for the current-year quarter and first nine months of fiscal 2009, respectively, and $0.7 million and $4.1 million in the prior-year quarter and first nine months of fiscal 2008, respectively. Included in Industrial International operating income are business realignment charges of $9.3 million and $12.4 million for the current-year quarter and first nine months of fiscal 2009, respectively, and $0.2 million and $0.3 million in the prior-year quarter and first nine months of fiscal 2008, respectively. The business realignment charges resulted from actions the Company took to structure appropriately the Industrial operations to operate in their current and anticipated economic environment. Also included in Industrial North American operating income for the current-year quarter and first nine months of fiscal

- 18 -

2009 is income of $12.3 million related to retiree medical costs (see Note 9 to the Consolidated Financial Statements for further discussion).

The Company expects to continue to take the actions necessary to structure appropriately the Industrial Segment to operate in its current economic environment. Such actions may include the necessity to record additional business realignment charges in fiscal 2009.

The decrease in backlog from a year ago and the June 30, 2008 amount of $1,743.8 million is primarily due to lower order rates experienced across all businesses, with the largest decline occurring in the Industrial International businesses. The Company anticipates Industrial North American sales for fiscal 2009 to decline between 13.4 percent to 13.2 percent from the fiscal 2008 level and Industrial International sales for fiscal 2009 to decline between 22.7 percent to 22.5 percent from the fiscal 2008 level. Industrial North American operating margins in fiscal 2009 are expected to range from 10.7 percent to 11.0 percent and Industrial International operating margins are expected to range from 9.5 percent to 9.9 percent.

Aerospace Segment

The increase in sales in the Aerospace Segment for the current-year quarter is primarily due to an increase in commercial original equipment manufacturer (OEM) volume as well as an increase in military OEM and aftermarket volume partially offset by lower commercial aftermarket volume. The increase in sales for the first nine months of fiscal 2009 is primarily due to an increase in both commercial and military OEM and aftermarket volume. Margins for the current-year quarter were lower primarily due to higher engineering development costs and a higher concentration of sales in the lower margin OEM businesses. Margins for the first nine months of fiscal 2009 were higher due primarily to favorable product mix more than offsetting higher engineering development costs. Margins for the first nine months of fiscal 2008 were adversely affected by an increase in contract reserves. Operating income for the current-year quarter and first nine months of fiscal 2009 includes income of $6.3 million related to retiree medical costs (see Note 9 to the Consolidated Financial Statements for further discussion).

The slight decrease in backlog from the prior-year quarter and the June 30, 2008 amount of $1,737.4 million is primarily due to shipments exceeding order rates primarily in the commercial OEM and aftermarket businesses. For fiscal 2009, sales are expected to increase by 2.3 percent to 2.5 percent from the fiscal 2008 level and operating margins are expected to range from 13.4 percent to 13.7 percent. Lower commercial aftermarket volume in future product mix and higher than expected engineering development costs could result in lower margins.

Climate & Industrial Controls Segment

The Climate & Industrial Controls Segment operations experienced the following percentage changes in net sales in the current-year period compared to the equivalent prior-year period:

The above presentation reconciles the percentage changes in net sales of the Climate & Industrial Controls Segment reported in accordance with U.S. GAAP to percentage changes in net sales adjusted to remove the effects of acquisitions made within the prior four fiscal quarters as well as the effects of currency exchange rates. The effects of acquisitions and currency exchange rates are removed to allow investors and the Company to meaningfully evaluate the percentage changes in net sales on a comparable basis from period to period.

Excluding the effect of foreign currency changes, the decrease in sales in the Climate & Industrial Controls Segment for the current-year quarter and first nine months of fiscal 2009 is primarily due to lower end-user demand experienced in most markets, most notably the residential air conditioning, heavy-duty truck and automotive markets. The lower margins are primarily due to the lower sales volume, resulting in manufacturing inefficiencies and higher business realignment charges. Operating income for the current-year quarter and first nine months of fiscal 2009 include income of $2.3 million related to retiree medical costs (see Note 9 to the Consolidated Financial Statements for further discussion).

The decrease in backlog from the prior-year quarter and the June 30, 2008 amount of $170.1 million is primarily due to lower order rates in most markets, most notably in the heavy-duty truck and automotive markets. For fiscal 2009, sales are expected to decline by 26.8 percent to 26.6 percent from the fiscal 2008 level and an operating loss is expected to range from 0.7 percent to 0.1 percent of sales. The Company expects to continue to take the actions necessary to structure appropriately the Climate & Industrial Controls Segment operations. Such actions may include the necessity to record additional business realignment charges in fiscal 2009.

Corporate and Other

Corporate general and administrative expenses were $40.4 million in the current-year quarter compared to $48.2 million in the prior-year quarter and were $123.1 million for the first nine months of fiscal 2009 compared to $133.5 million for the first nine months of fiscal 2008. As a percent of sales, corporate general and administrative expenses for the current-year quarter were 1.7 percent compared to 1.5 percent for the prior-year quarter and were 1.5 percent for both the first nine months of fiscal 2009 and fiscal 2008. The lower expense in the current-year quarter is primarily due to lower incentive compensation expenses and the lower expense for the first nine months of fiscal 2009 is primarily due to lower legal fees and lower incentive compensation expenses.

Other expense (in the Business Segment Results) included the following:
