NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Business Description and Basis of Presentation

Rockwell Collins, Inc. (the Company or Rockwell Collins) designs, produces and supports communications and aviation electronics for commercial and military customers worldwide.

The Company operates on a 52/53 week fiscal year, with quarters ending on the Friday closest to the last day of the calendar quarter. For ease of presentation, March 31 and September 30 are utilized consistently throughout these financial statements and notes to represent the period end date.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America and with the instructions to Form 10-Q of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in annual financial statements have been condensed or omitted. These financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended September 30, 2010.

In the opinion of management, the unaudited financial statements contain all adjustments, consisting of adjustments of a normal recurring nature, necessary to present fairly the financial position, results of operations and cash flows for the periods presented. The results of operations for the three and six months ended March 31, 2011 are not necessarily indicative of the results that may be expected for the full year.

The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements. Actual results could differ from those estimates and assumptions.

Certain prior period amounts on the Condensed Consolidated Statement of Operations were restated to correct the previous presentation of certain sales and cost of sales. Specifically, $32 million and $53 million were reclassified from Product Sales to Service Sales and $20 million and $33 million were reclassified from Product Cost of Sales to Service Cost of Sales for the three and six months ended March 31, 2010, respectively. These adjustments did not impact previously reported net income, nor did they have any effect on the Company’s financial position, net income or cash flows for the three or six months ended March 31, 2010.

2. Recently Issued Accounting Standards

In April 2010, the Financial Accounting Standards Board (FASB) issued guidance related to the milestone method of accounting for research or development arrangements in which a vendor satisfies its performance obligations over time and all or a portion of the arrangement consideration is contingent upon the achievement of a milestone. This guidance became effective for the Company in the first quarter of 2011 with no significant impact to the Company’s financial statements.

In September 2009, the FASB amended the guidance for allocating revenue to multiple deliverables in a contract. In accordance with the amendment, companies can allocate consideration in a multiple element arrangement in a manner that better reflects the transaction economics. When vendor specific objective evidence or third party evidence for deliverables in an arrangement cannot be determined, companies will now be allowed to develop a best estimate of the selling price to separate deliverables and allocate arrangement consideration using the relative selling price method. Additionally, use of the residual method has been eliminated. The Company adopted this guidance in the first quarter of 2011 with no significant impact to the Company's financial position, results of operations or cash flows as the Company generally allocates revenue to deliverables based on the prices charged when sold separately by the Company.

3. Acquisitions

Computing Technologies for Aviation, Inc.

On January 10, 2011, the Company acquired all of the shares of Computing Technologies for Aviation, Inc. (CTA). The purchase price, net of cash acquired, was approximately $11 million. CTA is headquartered in Charlottesville, Virginia and is a leading provider of flight operations management solutions for corporate flight departments and other aviation customers. The Company is in the process of allocating the purchase price and obtaining a valuation for acquired intangible assets. Based on the Company’s preliminary allocation of the purchase price, $9 million has been allocated to goodwill and $3 million to finite-lived intangible assets with a weighted average life of approximately 9 years. The excess purchase price over net assets acquired reflects the Company’s view that this acquisition will broaden the Company’s information management flight operations' capabilities. None of the goodwill resulting from the acquisition is tax deductible. The goodwill is included within the Commercial Systems segment.

On December 20, 2010, the Company acquired all the shares of Blue Ridge Simulation, Inc. (Blue Ridge Simulation). Blue Ridge Simulation, with headquarters located in Leesburg, Virginia, is a leading supplier of high-performance sensor simulation for U.S. Department of Defense, commercial and international training applications. The cash purchase price, net of cash acquired, was $6 million. The Company is in the process of allocating the purchase price and obtaining a valuation for acquired intangible assets. Based on the Company’s preliminary allocation of the purchase price, $6 million has been allocated to goodwill and $1 million to finite-lived intangible assets with a weighted average life of approximately 9 years. The excess purchase price over net assets acquired reflects the Company’s view that this acquisition will enhance the Company’s integrated training solutions. All goodwill resulting from the acquisition is tax deductible. The goodwill is included in the Government Systems segment.

AR Group, Inc.

On December 31, 2009, the Company acquired all the shares of AR Group, Inc. and affiliates (Air Routing). Air Routing, with headquarters located in Houston, Texas, is a leading global provider of trip support services for business aircraft flight operations. The cash purchase price, net of cash acquired, was $91 million. In the fourth quarter of 2010, the purchase price allocation was finalized with $58 million allocated to goodwill and $39 million to finite-lived intangible assets with a weighted average life of approximately 14 years. The excess purchase price over net assets acquired reflects the Company’s view that this acquisition will broaden the Company’s information management flight operations' capabilities. None of the goodwill resulting from the acquisition is tax deductible. Air Routing goodwill is included within the Commercial Systems segment.

SEOS Group Limited

On November 24, 2008, the Company acquired all the shares of SEOS Group Limited (SEOS), a leading global supplier of highly realistic visual display solutions for commercial and military flight simulators. The initial purchase price, net of cash acquired, was $28 million. The purchase agreement contemplated additional consideration to be paid post-closing, contingent upon the achievement of certain milestones and not to exceed $8 million. In March 2011, the earn-out contingency was settled in full resulting in no additional consideration being paid. In addition, the Company received $2 million of cash during the second quarter of 2011 related to the favorable settlement of various post-closing disputes. The final purchase price, net of the favorable post-closing settlement adjustment, was $26 million.

4. Receivables, Net

Receivables, net are summarized as follows:

	March 31,			September 30,

Total U.S. Government receivables include $172 million and $119 million of unbilled receivables net of progress payments at March 31, 2011 and September 30, 2010, respectively.

Unbilled receivables principally represent sales recorded under the percentage-of-completion method of accounting that have not been billed to customers in accordance with applicable contract terms.

Total		779			684
Pre-production engineering costs		393			320
Inventories, net	$	1,172		$	1,004

The Company defers certain pre-production engineering costs during the development phase of an aircraft program in connection with long-term supply arrangements that contain contractual guarantees for reimbursement from customers. Such customer guarantees generally take the form of a minimum order quantity with quantified reimbursement amounts if the minimum order quantity is not taken by the customer. These costs are deferred to the extent of the contractual guarantees and are amortized over their estimated useful lives, up to 15 years, as a component of cost of sales. Amortization is typically based on the Company’s expectation of delivery rates on a program-by-program basis. The estimated useful life is limited to the amount of time the Company is virtually assured to earn revenues through a contractually enforceable right included in long-term supply arrangements with the Company’s customers. Pre-production engineering costs incurred pursuant to supply arrangements that do not contain customer guarantees for reimbursement are expensed as incurred.

Rockwell Collins provides up-front sales incentives prior to delivering products or performing services to certain commercial customers in connection with sales contracts. Up-front sales incentives are recorded as a Customer Relationship Intangible Asset and amortized over the period the Company has received a contractually enforceable right related to the incentives, up to 15 years. Amortization is typically based on the Company’s expectation of delivery rates on a program-by-program basis. Up-front sales incentives consisting of cash payments or customer account credits are amortized as a reduction of sales whereas incentives consisting of free products are amortized as cost of sales.

Amortization expense for intangible assets for the three and six months ended March 31, 2011 was $11 million and $19 million, respectively, compared to $9 million and $18 million for the three and six months ended March 31, 2010. Annual amortization expense for intangible assets for 2011, 2012, 2013, 2014 and 2015 is expected to be $37 million, $39 million, $34 million, $34 million and $31 million, respectively.

Other assets	$	198	$	207

Investments in Equity Affiliates

Investments in equity affiliates primarily consist of four joint ventures. Each joint venture is 50 percent owned by the Company and accounted for under the equity method. Under the equity method of accounting for investments, the Company’s proportionate share of the earnings or losses of its equity affiliates are included in Net Income and classified as Other Income, Net in the Condensed Consolidated Statement of Operations. For segment performance reporting purposes, Rockwell Collins’ share of earnings or losses of equity affiliates are included in the operating results of the Government Systems segment.

In the normal course of business or pursuant to the underlying joint venture agreements, the Company may sell products or services to equity affiliates. The Company defers a portion of the profit generated from these sales equal to its ownership interest in the equity affiliates until the underlying product is ultimately sold to an unrelated third party. Sales to equity affiliates were $25 million and $50 million for the three and six months ended March 31, 2011, respectively, and $19 million and $39 million for the three and six months ended March 31, 2010, respectively.

Assets Held-for-Sale

Assets held-for-sale includes the carrying cost for the Company's vacated land and facility in San Jose, California. In September 2009, the Company announced plans to close this facility and relocate engineering, production and service work to other existing facilities. In 2010, the San Jose facility was vacated, actively marketed and prepared for sale. The facility is recorded at fair market value based upon ongoing negotiations with a third party.

9. Other Current Liabilities

Other		91		83
Other current liabilities	$	248	$	242

The Company provides sales incentives to certain commercial customers in connection with sales contracts. Incentives earned by customers based on purchases of Company products or services are recognized as a liability when the related sale is recorded. Incentives consisting of cash payments or customer account credits are recognized as a reduction of sales while incentives consisting of free-of-charge hardware and account credits where the customer’s use is restricted to future purchases are recognized as cost of sales.

10. Debt

Short-term Debt

Under the Company’s commercial paper program, the Company may sell up to $850 million face amount of unsecured short-term promissory notes in the commercial paper market. The commercial paper notes may bear interest or may be sold at a discount, and have a maturity of not more than 364 days from the time of issuance. At March 31, 2011, short-term commercial paper borrowings outstanding were $15 million with a weighted average interest rate and maturity period of 0.21 percent and 3 days, respectively. At September 30, 2010, there were no outstanding short-term commercial paper borrowings.

At March 31, 2011, an additional $13 million of short-term debt was outstanding under a five-year unsecured variable rate loan agreement for a non-U.S. subsidiary that was entered into in June 2006 and is due in June 2011. At September 30, 2010, the balance of this variable rate loan facility agreement was $24 million. The variable rate loan facility agreement contains customary loan covenants, none of which are financial covenants. Failure to comply with customary covenants or the occurrence of customary events of default contained in the agreement would require the repayment of any outstanding borrowings under the agreement.

Revolving Credit Facilities

The Company has an $850 million unsecured revolving credit facility with various banks that matures in March 2012. The credit facility has options to extend the term for up to two one-year periods and/or increase the aggregate principal amount up to $1.2 billion. These options are subject to the approval of the lenders. This credit facility exists primarily to support the Company’s commercial paper program, but may be used for other purposes in the event access to the commercial paper market is impaired or eliminated. The credit facility includes one financial covenant requiring the Company to maintain a consolidated debt to total capitalization ratio of not greater than 60 percent. The ratio excludes the accumulated other comprehensive loss equity impact related to defined benefit retirement plans. The ratio was 16 percent as of March 31, 2011. In addition, the credit facility contains other non-financial covenants that require the Company to satisfy certain conditions in order to incur debt secured by liens, engage in sale/leaseback transactions or merge or consolidate with another entity. Borrowings under this credit facility bear interest at the London Interbank Offered Rate (LIBOR) plus a variable margin based on the Company’s unsecured long-term debt rating or, at the Company’s option, rates determined by competitive bid. At March 31, 2011 and September 30, 2010, there were no outstanding borrowings under this revolving credit facility.

(Unaudited)

In addition, short-term credit facilities available to non-U.S. subsidiaries amounted to $61 million as of March 31, 2011, of which $19 million was utilized to support commitments in the form of commercial letters of credit. As of March 31, 2011 and September 30, 2010, there were no short-term borrowings outstanding under the Company’s non-U.S. subsidiaries’ credit facilities.

At March 31, 2011 and September 30, 2010, there were no significant commitment fees or compensating balance requirements under any of the Company’s credit facilities.

Long-term Debt

In addition to the Company’s credit facilities and commercial paper program, the Company has a shelf registration statement filed with the Securities and Exchange Commission pursuant to which the Company can publicly offer and sell securities. This shelf registration covers an unlimited amount of debt securities, common stock, preferred stock or warrants that may be offered in one or more offerings on terms to be determined at the time of sale.

On May 6, 2009, the Company issued $300 million of 5.25 percent fixed rate unsecured debt due July 15, 2019 (the 2019 Notes). The net proceeds to the Company from the sale of the 2019 Notes, after deducting a $2 million discount and $2 million of debt issuance costs, were $296 million. The 2019 Notes are included in the Condensed Consolidated Statement of Financial Position net of the unamortized discount within the caption Long-term Debt, Net. The debt issuance costs are capitalized within Other Assets on the Condensed Consolidated Statement of Financial Position. The discount and debt issuance costs are amortized over the life of the 2019 Notes and recorded in Interest Expense. In January 2010, the Company entered into interest rate swap contracts which effectively converted $150 million of the 2019 Notes to floating rate debt based on six-month LIBOR plus 1.235 percent. See Notes 16 and 17 for additional information relating to the interest rate swap contracts.

On November 20, 2003, the Company issued $200 million of 4.75 percent fixed rate unsecured debt due December 1, 2013 (the 2013 Notes). At the time of the debt issuance, the Company entered into interest rate swap contracts which effectively converted $100 million of the 2013 Notes to floating rate debt based on six-month LIBOR less .075 percent. See Notes 16 and 17 for additional information relating to the interest rate swap contracts.

The 2019 and 2013 Notes each contain covenants that require the Company to satisfy certain conditions in order to incur debt secured by liens, engage in sales/leaseback transactions, merge or consolidate with another entity or transfer substantially all of the Company’s assets.

Long-term debt and a reconciliation to the carrying amount is summarized as follows:

	March 31,		September 30,
(in millions)	2011		2010
Principal amount of 2019 Notes, net of discount	$	299	$	299

The Company was in compliance with all debt covenants at March 31, 2011 and September 30, 2010.

Interest paid on debt for the six months ended March 31, 2011 and 2010 was $8 million and $11 million, respectively.

Pension Plan Funding

The Company’s objective with respect to the funding of its pension plans is to provide adequate assets for the payment of future benefits. Pursuant to this objective, the Company will fund its pension plans as required by governmental regulations and may consider discretionary contributions as conditions warrant. In January 2011, the Company made a $100 million contribution to the U.S. qualified pension plan. The Company is not required by government regulations to make any additional contributions to the U.S. qualified pension plan in 2011. Any additional future contributions necessary to satisfy the minimum statutory funding requirements are dependent upon actual plan asset returns and interest rates. The Company may elect to make additional discretionary contributions during 2011 to further improve the funded status of this plan. Contributions to the non-U.S. plans and the U.S. non-qualified plan are expected to total $13 million in 2011. For the six months ended March 31, 2011 and 2010, the Company made contributions to the non-U.S. plans and the U.S. non-qualified pension plan of $7 million and $7 million, respectively.

The maximum number of shares of common stock that can be issued with respect to the performance shares granted in 2011 based on the achievement of performance targets for fiscal years 2011 through 2013 is 460 thousand.

The fair value of each option granted by the Company was estimated using a binomial lattice pricing model and the following assumptions:

	2011			2010
	Grants			Grants
Risk-free interest rate		0.5% - 3.9	%		2.7	%
Expected dividend yield		1.7	%		2.3	%
Expected volatility		27.0	%		27.0	%
Expected life	8 years			7 years

In 2010, the risk-free interest rate was equal to a single U.S. Treasury yield based upon the period over which employees were expected to hold options. In 2011, the risk-free interest rate selected was changed to reflect a range of U.S. Treasury yields corresponding to anticipated option exercises over the ten year contractual term. A range of risk-free interest rates more closely aligns with the assumptions used in the binomial lattice pricing model. This change did not significantly impact the fair value of options granted.

Employee Benefits Paid in Company Stock

During the six months ended March 31, 2011 and 2010, 0.5 million and 0.6 million shares, respectively, of Company common stock were issued to employees under the Company’s employee stock purchase and defined contribution savings plans at a value of $33 million and $31 million for the respective periods.

15. Income Taxes

At the end of each interim reporting period, the Company makes an estimate of the annual effective income tax rate. Tax items included in the annual effective income tax rate are pro-rated for the full year and tax items discrete to a specific quarter are included in the effective income tax rate for that quarter. The estimate used in providing for income taxes on a year-to-date basis may change in subsequent interim periods. During the three months ended March 31, 2011 and 2010, the effective income tax rate was 31.5 percent and 24.5 percent, respectively and for the six months ended March 31, 2011 and 2010, the effective income tax rate was 26.9 percent and 28.6 percent, respectively.

The higher effective income tax rate for the three months ended March 31, 2011, as compared to the same period of the prior year, was primarily due to the completion of the Internal Revenue Service (IRS) examination of taxable years ended September 30, 2006 and 2007 which resulted in a benefit to the Company’s effective income tax rate by about 10 percent for the three months ended March 31, 2010. This prior year benefit was partially offset by an increase to the Company’s effective income tax rate for the three months ended March 31, 2010 of about 2 percent related to differences in the availability of the Federal Research and Development Tax Credit (Federal R&D Tax Credit), which expired on December 31, 2009.

The lower effective income tax rate for the six months ended March 31, 2011, as compared to the same period of the prior year which included the favorable IRS adjustments mentioned above, was primarily due to the differences in the availability of the Federal R&D Tax Credit, which expired on December 31, 2009, and the increased tax benefit of the Domestic Manufacturing Deduction (DMD) for fiscal year 2011, as compared to the DMD tax benefit for fiscal year 2010 which was two-thirds of the full benefit.

On December 17, 2010, the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 was enacted, which retroactively reinstated and extended the Federal R&D Tax Credit from January 1, 2010 to December 31, 2011. The retroactive benefit for the previously expired period from January 1, 2010 to September 30, 2010 was recognized and lowered the Company’s effective income tax rate by about 4 percent for the six months ended March 31, 2011.

The Company’s U.S. Federal income tax returns for the tax years ended September 30, 2007 and prior have been audited by the IRS and are closed to further adjustments by the IRS except for refund claims the Company filed for the tax years ended September 30, 2006 and 2007. The IRS is currently auditing the Company’s tax returns for the tax years ended September 30, 2008 and 2009 as well as refund claims for prior years. The Company is also currently under audit in various U.S. states and non-U.S. jurisdictions. The U.S. state and non-U.S. jurisdictions have statutes of limitations generally ranging from 3 to 5 years. The Company believes it has adequately provided for any tax adjustments that may result from the various audits.

The Company had net income tax payments of $41 million and $54 million during the six months ended March 31, 2011 and 2010, respectively.

The Company had gross unrecognized tax benefits recorded within Other Liabilities in the Condensed Consolidated Statement of Financial Position of $92 million and $78 million as of March 31, 2011 and September 30, 2010, respectively. The total amounts of unrecognized tax benefits that, if recognized, would affect the effective income tax rate were $52 million at both March 31, 2011 and September 30, 2010. Although the timing and outcome of tax settlements are uncertain, it is reasonably possible that during the next 12 months, a reduction in unrecognized tax benefits may occur in the range of $0 to $36 million based on the outcome of tax examinations or as a result of the expiration of various statutes of limitations.

The total amount of interest and penalties recognized within Other Liabilities in the Condensed Consolidated Statement of Financial Position was $6 million and $5 million as of March 31, 2011 and September 30, 2010, respectively. The total amount of interest and penalties recorded as an expense or (income) within Income Tax Expense in the Condensed Consolidated Statement of Operations was $1 million and $(5) million for the three months ended March 31, 2011 and March 31, 2010, respectively, and $1 million and $(4) million for the six months ended March 31, 2011 and March 31, 2010, respectively.

16. Fair Value Measurements

The FASB defines fair value as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. The FASB’s guidance classifies the inputs used to measure fair value into the following hierarchy:

Level 1 - quoted prices (unadjusted) in active markets for identical assets or liabilities

Level 2 - quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument

Level 3 - unobservable inputs based on the Company’s own assumptions used to measure assets and liabilities at fair value

A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

The fair value of the Company’s financial assets and liabilities measured at fair value on a recurring basis as of March 31, 2011 and September 30, 2010 are as follows:

		March 31, 2011			September 30, 2010
	Fair Value	Fair Value			Fair Value
(in millions)	Hierarchy	Asset (Liability)			Asset (Liability)
Deferred compensation plan investments	Level 1	$	41		$	37
Assets held-for-sale	Level 2		14			14
Interest rate swap assets	Level 2		10			26
Foreign currency forward exchange contract assets	Level 2		10			9
Foreign currency forward exchange contract liabilities	Level 2		(8	)		(8	)

There were no nonfinancial assets or nonfinancial liabilities recognized at fair value on a nonrecurring basis and there were no transfers between Levels of the fair value hierarchy during the six months ended March 31, 2011.

Long-term debt		(499	)		(541	)		(499	)		(558	)

The fair value of cash and cash equivalents and short-term investments approximate their carrying value due to the short-term nature of the instruments and are within Level 1 of the fair value hierarchy. Short-term investments consist of certificates of deposit with a maturity date of less than one year. The fair value of short-term debt approximates its carrying value due to the short-term nature of the debt. Fair value information for long-term debt is based on current market interest rates and estimates of current market conditions for instruments with similar terms, maturities, and degree of risk. The carrying amount and fair value of long-term debt excludes the interest rate swaps fair value adjustment. These fair value estimates do not necessarily reflect the amounts the Company would realize in a current market exchange.

17. Derivative Financial Instruments

Interest Rate Swaps

The Company manages its exposure to interest rate risk by maintaining an appropriate mix of fixed and variable rate debt, which over time should moderate the costs of debt financing. When considered necessary, the Company may use financial instruments in the form of interest rate swaps to help meet this objective. In January 2010, the Company entered into two interest rate swap contracts (the 2019 Swaps) which expire on July 15, 2019 and effectively converted $150 million of the 2019 Notes to floating rate debt based on six-month LIBOR plus 1.235 percent. On November 20, 2003, the Company entered into two interest rate swap contracts (the 2013 Swaps) which expire on December 1, 2013 and effectively converted $100 million of the 2013 Notes to floating rate debt based on six-month LIBOR less .075 percent.

The Company has designated the 2019 and 2013 Swaps (the Swaps) as fair value hedges. At March 31, 2011 and September 30, 2010, interest rate swaps were recorded within Other Assets at a fair value of $10 million and $26 million, respectively, offset by a fair value adjustment to Long-term Debt (Note 10) of $10 million and $26 million, respectively. Cash payments or receipts between the Company and the counterparties to the Swaps are recorded as an adjustment to interest expense.

Foreign Currency Forward Exchange Contracts

The Company transacts business in various foreign currencies which subjects the Company’s cash flows and earnings to exposure related to changes in foreign currency exchange rates. These exposures arise primarily from purchases or sales of products and services from third parties and intercompany transactions. Foreign currency forward exchange contracts provide for the purchase or sale of foreign currencies at specified future dates at specified exchange rates and are used to offset changes in the fair value of certain assets or liabilities or forecasted cash flows resulting from transactions denominated in foreign currencies. As of March 31, 2011 and September 30, 2010, the Company had outstanding foreign currency forward exchange contracts with notional amounts of $427 million and $404 million, respectively. These notional values consist primarily of contracts for the European euro and British pound sterling, and are stated in U.S. dollar equivalents at spot exchange rates at the respective dates.

The fair values of derivative instruments are presented on a gross basis as the Company does not have any derivative contracts which are subject to master netting arrangements. As of March 31, 2011 and September 30, 2010, $1 million and $1 million, respectively, of foreign currency forward exchange contracts, classified within Other current assets, were not designated as hedging instruments.

The effect of derivative instruments on the Condensed Consolidated Statement of Operations for the six months ended March 31, 2011 and 2010 is as follows:

		Amount of Gain (Loss)

There was no significant impact to the Company’s earnings related to the ineffective portion of any hedging instruments during the three and six months ended March 31, 2011 and 2010. In addition, there was no significant impact to the Company’s earnings when a hedged firm commitment no longer qualified as a fair value hedge or when a hedged forecasted transaction no longer qualified as a cash flow hedge during the three and six months ended March 31, 2011 and 2010.

Cash flow hedges are designated as fair value hedges once the underlying transaction is recorded on the balance sheet, or approximately 60 days from the maturity date of the hedge. The Company expects to reclassify approximately $1 million of net gains into earnings over the next 12 months. The maximum duration of a foreign currency cash flow hedge contract at March 31, 2011 was 112 months.

18. Guarantees and Indemnifications

Product warranty costs

Accrued liabilities are recorded to reflect the Company’s contractual obligations relating to warranty commitments to customers. Warranty coverage of various lengths and terms is provided to customers depending on standard offerings and negotiated contractual agreements. An estimate for warranty expense is recorded at the time of sale based on the length of the warranty and historical warranty return rates and repair costs.

Guarantees

The Company provides a parent company guarantee related to various obligations of its 50 percent owned joint venture, Quest Flight Training Limited (Quest). The Company has guaranteed, jointly and severally with Quadrant Group plc (Quadrant), the other joint venture partner, the performance of Quest in relation to its contract with the United Kingdom Ministry of Defence (which expires in 2030) and the performance of certain Quest subcontractors (up to $2 million). In addition, the Company has also pledged equity shares in Quest to guarantee payment by Quest of a loan agreement executed by Quest. In the event of default on this loan agreement, the lending institution can request that the trustee holding such equity shares surrender them to the lending institution in order to satisfy all amounts then outstanding under the loan agreement. As of March 31, 2011, the outstanding loan balance was approximately $6 million. Quadrant has made an identical pledge to guarantee this obligation of Quest.

Should Quest fail to meet its obligations under these agreements, these guarantees may become a liability of the Company. As of March 31, 2011, the Quest guarantees are not reflected on the Company’s Condensed Consolidated Statement of Financial Position because the Company believes that Quest will meet all of its performance and financial obligations in relation to its contract with the United Kingdom Ministry of Defence and the loan agreement.

Letters of credit

The Company has contingent commitments in the form of letters of credit. Outstanding letters of credit are issued by banks on the Company’s behalf to support certain contractual obligations to its customers. If the Company fails to meet these contractual obligations, these letters of credit may become liabilities of the Company. Total outstanding letters of credit at March 31, 2011 were $85 million. These commitments are not reflected as liabilities on the Company’s Condensed Consolidated Statement of Financial Position.

Indemnifications

The Company enters into indemnifications with lenders, counterparties in transactions such as administration of employee benefit plans and other customary indemnifications with third parties in the normal course of business. The following are other than customary indemnifications based on the judgment of management.

The Company became an independent, publicly held company on June 29, 2001, when Rockwell International Corporation (Rockwell), renamed Rockwell Automation Inc., spun off its former avionics and communications business and certain other assets and liabilities of Rockwell by means of a distribution of all the Company’s outstanding shares of common stock to the shareowners of Rockwell in a tax-free spin-off (the spin-off). In connection with the spin-off, the Company may be required to indemnify certain insurers against claims made by third parties in connection with the Company’s legacy insurance policies.

In connection with agreements for the sale of portions of its business, the Company at times retains various liabilities of a business that relate to events occurring prior to its sale, such as tax, environmental, litigation and employment matters. The Company at times indemnifies the purchaser of a Rockwell Collins business in the event that a third party asserts a claim that relates to a liability retained by the Company.

The Company also provides indemnifications of varying scope and amounts to certain customers against claims of product liability or intellectual property infringement made by third parties arising from the use of Company or customer products or intellectual property. These indemnifications generally require the Company to compensate the other party for certain damages and costs incurred as a result of third party product liability or intellectual property claims arising from these transactions.

(Unaudited)

The amount the Company could be required to pay under its indemnification agreements is generally limited based on amounts specified in the underlying agreements, or in the case of some agreements, the maximum potential amount of future payments that could be required is not limited. When a potential claim is asserted under these agreements, the Company considers such factors as the degree of probability of an unfavorable outcome and the ability to make a reasonable estimate of the amount of loss. A liability is recorded when a potential claim is both probable and estimable. The nature of these agreements prevents the Company from making a reasonable estimate of the maximum potential amount it could be required to pay should counterparties to these agreements assert a claim; however, the Company currently has no material claims pending related to such agreements.

19. Environmental Matters

The Company is subject to federal, state and local regulations relating to the discharge of substances into the environment, the disposal of hazardous wastes and other activities affecting the environment that have had and will continue to have an impact on the Company’s manufacturing operations. These environmental protection regulations may require the investigation and remediation of environmental impairments at current and previously owned or leased properties. In addition, lawsuits, claims and proceedings have been asserted on occasion against the Company alleging violations of environmental protection regulations, or seeking remediation of alleged environmental impairments, principally at previously owned or leased properties. As of March 31, 2011, the Company is involved in the investigation or remediation of eight sites under these regulations or pursuant to lawsuits asserted by third parties. Management estimates that the total reasonably possible future costs the Company could incur for seven of these sites is not significant. Management estimates that the total reasonably possible future costs the Company could incur from one of these sites to be approximately $9 million. The Company has recorded environmental reserves for this site of $3 million as of March 31, 2011, which represents management’s best estimate of the probable future cost for this site.

To date, compliance with environmental regulations and resolution of environmental claims has been accomplished without material effect on the Company’s liquidity and capital resources, competitive position or financial condition. Management believes that expenditures for environmental capital investment and remediation necessary to comply with present regulations governing environmental protection and other expenditures for the resolution of environmental claims will not have a material adverse effect on the Company’s business or financial position, but could possibly be material to the results of operations or cash flows of any one quarter.

20. Legal Matters

The Company is subject to various lawsuits, claims and proceedings that have been or may be instituted or asserted against the Company relating to the conduct of the Company’s business, including those pertaining to product liability, antitrust, intellectual property, safety and health, exporting and importing, contract, employment and regulatory matters. Although the outcome of these matters cannot be predicted with certainty and some lawsuits, claims or proceedings may be disposed of unfavorably to the Company, management believes the disposition of matters that are pending or asserted are not expected to have a material adverse effect on the Company’s business or financial position, but could possibly be material to the results of operations or cash flows of any one quarter.

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

RESULTS OF OPERATIONS

The following management discussion and analysis is based on financial results for the three and six months ended March 31, 2011 and 2010 and should be read in conjunction with the unaudited condensed consolidated financial statements and notes thereto in Item 1 of Part I of this quarterly report.

Three Months Ended March 31, 2011 and 2010

Sales

	Three Months Ended
	March 31
(dollars in millions)	2011			2010
Total sales	$	1,223		$	1,142
Percent increase		7	%

Total sales for the three months ended March 31, 2011 increased $81 million compared to the three months ended March 31, 2010 due to a $58 million increase in Commercial Systems sales and a $23 million increase in Government Systems sales. See the following Government Systems and Commercial Systems Financial Results sections for further discussion of sales.

Cost of Sales

	Three Months Ended
	March 31
(dollars in millions)	2011			2010
Total cost of sales	$	870		$	828
Percent of total sales		71.1	%		72.5	%

Cost of sales consists of all costs incurred to design and manufacture our products and includes research and development (R&D), raw material, labor, facility, product warranty, depreciation, amortization and other related expenses.

Total cost of sales for the three months ended March 31, 2011 increased $42 million, or 5 percent, from the same period of 2010, primarily due to the following:

· A $39 million increase resulting from the $81 million of sales growth discussed in the Commercial Systems and Government Systems Financial Results sections below.

· A $11 million increase attributable to higher employee incentive compensation expenses. Employee incentive compensation expense included within cost of sales was $18 million and $7 million for the three months ended March 31, 2011 and 2010, respectively.

· The above items are partially offset by an $8 million reduction to cost of sales attributable to lower defined benefit pension expense. As discussed in the Retirement Plans section below, the reduction in pension expense was primarily due to a change in the period of time over which actuarial gains and losses are amortized. For the three months ended March 31, 2011, pension income reduced cost of sales by $5 million, compared to $3 million of pension expense during the same period last year.

22

R&D expense is included as a component of cost of sales and is summarized as follows:

	Three Months Ended
	March 31
(dollars in millions)	2011			2010
Customer-funded:
Government Systems	$	117		$	114
Commercial Systems		19			19
Total customer-funded		136			133
Company-funded:
Government Systems		28			31
Commercial Systems		60			56
Total company-funded		88			87
Total research and development expense		224			220
Percent of total sales		18.3	%		19.3	%

Customer-funded R&D expenditures are incurred pursuant to contractual arrangements and are accounted for as contract costs within cost of sales with the reimbursement accounted for as a sale when earned. Company-funded R&D expense consists primarily of payroll-related expenses of employees engaged in R&D activities, engineering related product materials and equipment and subcontracting costs.

Total R&D expense for the three months ended March 31, 2011 increased $4 million from the same period last year. The overall increase in total R&D expense was primarily due to $4 million of higher company-funded R&D within Commercial Systems that resulted from software verification testing on certain air transport programs, as well as a $3 million increase in customer-funded R&D within Government Systems associated with development effort on the Common Range Integrated Instrumentation System (CRIIS) program. These increases were offset by a $3 million reduction in company-funded R&D within Government Systems.

Selling, General and Administrative Expenses

	Three Months Ended
	March 31
(dollars in millions)	2011			2010
Selling, general and administrative expenses	$	136		$	119
Percent of total sales		11.1	%		10.4	%

Selling, general and administrative (SG&A) expenses consist primarily of personnel, facility and other expenses related to employees not directly engaged in manufacturing, research or development activities. These activities include marketing and business development, finance, legal, information technology and other administrative and management functions.

Total SG&A expenses for the three months ended March 31, 2011 increased $17 million, or 14 percent, compared to the three months ended March 31, 2010, primarily due to the following:

· $8 million from higher employee incentive compensation costs and merit pay increases.

· A $6 million increase resulting from the pursuit of international business opportunities and our ongoing global expansion as we opened new offices in Paris, China and the Middle East.

23

Net Income and Diluted Earnings Per Share

	Three Months Ended
	March 31
(dollars in millions, except per share amounts)	2011			2010
Net income	$	150		$	148
Net income as a percent of sales		12.3	%		13.0	%
Diluted earnings per share	$	0.96		$	0.93

Net income for the three months ended March 31, 2011 increased to $150 million, or 12.3 percent of sales, from net income of $148 million, or 13.0 percent of sales, for the three months ended March 31, 2010. Net income for the three months ended March 31, 2010 includes a net benefit of $15 million, or 1.3 percent of sales, due to favorable adjustments resulting from the completion of an IRS examination, partially offset by the difference in availability of the Federal R&D Tax Credit. Diluted earnings per share increased 3 percent to $0.96 for the three months ended March 31, 2011 compared to $0.93 for the three months ended March 31, 2010. The increase in net income and diluted earnings per share was primarily the result of higher earnings from Commercial Systems as discussed in the Commercial Systems Financial Results section below, partially offset by the unfavorable impact of a higher effective income tax rate further discussed in the Income Taxes section.

Government Systems Financial Results

Government Systems Sales

The following table presents Government Systems sales by product category:

	Three Months Ended
	March 31
(dollars in millions)	2011			2010
Airborne solutions	$	497		$	455
Surface solutions		219			238
Total	$	716		$	693
Percent increase		3	%

Airborne solutions sales increased $42 million, or 9 percent, for the three months ended March 31, 2011 compared to the same period in the prior year, primarily due to the following:

· A $30 million increase from rotary wing avionics sales on various platforms.

· A $21 million increase resulting from the combined impact of increased development effort on the CRIIS program and a transition to low-rate initial production for an E-6 aircraft upgrade program.

· The above items were partially offset by a $17 million reduction in sales from the KC-135 Global Air Traffic Management program which is expected to complete this year.

Surface solutions sales decreased $19 million, or 8 percent, for the three months ended March 31, 2011 compared to the same period in the prior year, primarily due to the following:

· A $23 million reduction in revenue resulting from a recently completed satellite communication upgrade program.

· An $11 million decrease resulting from lower deliveries of iForce systems to the California Highway Patrol.

· The above items were partially offset by a $20 million increase to revenue resulting from a program to provide transportable cellular capabilities in Afghanistan.

Government Systems Segment Operating Earnings

	Three Months Ended
	March 31
(dollars in millions)	2011			2010
Segment operating earnings	$	150		$	150
Percent of sales		20.9	%		21.6	%

Government Systems operating earnings were $150 million, or 20.9 percent of sales, for the three months ended March 31, 2011, compared to operating earnings of $150 million, or 21.6 percent of sales, for the same period one year ago. Government Systems operating earnings were flat year over year, primarily due to the following:

· The $23 million increase in sales discussed in the Government Systems sales section above resulted in a $17 million increase to costs and incremental operating earnings of $6 million.

· The above item was offset by a $6 million reduction in operating earnings attributable to the combined impact of a $10 million increase in employee incentive compensation costs and a $4 million decrease in pension expense discussed in the Retirement Plans section below.

· In addition, operating earnings benefited from the absence of an unfavorable adjustment of $6 million that was recorded in the prior year and related to certain simulation and training solution contracts. The benefit was largely offset by higher selling, general, and administrative expenses and increased bid and proposal costs associated with new pursuits and other selling activities.

The decline in Government Systems operating earnings as a percent of sales during the three months ended March 31, 2011 compared to the same period last year was primarily due to higher employee incentive compensation costs, partially offset by higher sales volume and a reduction in pension expense.

Commercial Systems Financial Results

Commercial Systems Sales

The following table presents Commercial Systems sales by product category and type of product or service:

	Three Months Ended
	March 31
(dollars in millions)	2011			2010
Air transport aviation electronics:

Aftermarket		93			78
Total business and regional aviation electronics		231			198
Total	$	507		$	449
Percent increase		13	%

Total air transport aviation electronics sales increased $25 million, or 10 percent, for the three months ended March 31, 2011 compared to the same period in the prior year due to the following:

· Air transport original equipment manufacturer (OEM) revenues increased $19 million, or 17 percent, primarily due to increased sales of airline selectable equipment for Boeing 737 aircraft, higher product deliveries for Boeing 787 and increased deliveries of single-aisle in-flight entertainment products.

· Air transport aftermarket sales increased $12 million, or 12 percent, primarily related to an increase in service and support sales and higher aftermarket hardware revenues from spare parts.

25

· Wide-body in-flight entertainment products and services (Wide-body IFE) decreased $6 million. Wide-body IFE includes sales of twin-aisle IFE products and systems to customers in the air transport aviation electronics market and also includes related revenue from wide-body service and support activities. Previously, revenues from Wide-body IFE service and support activities were included in air transport aftermarket sales. For the three months ended March 31, 2010, $24 million was reclassified out of air transport aftermarket sales and into Wide-body IFE products and services in order to conform to the current period presentation.

Business and regional aviation electronics sales increased $33 million, or 17 percent, for the three months ended March 31, 2011 compared to the same period in the prior year due to the following:

· Business and regional OEM sales increased $18 million, or 15 percent, primarily due to the combined impact of higher product deliveries to Bombardier for the Global 5000 and Global Express platforms and increased avionics sales for Cessna’s CJ-4 aircraft which started production in the prior year.

· Business and regional aftermarket sales increased $15 million, or 19 percent, primarily due to $13 million of higher retrofits and spares sales from deliveries associated with border patrol and other special mission aircraft programs and increased service and support revenues.

Commercial Systems Segment Operating Earnings

	Three Months Ended
	March 31
(dollars in millions)	2011			2010
Segment operating earnings	$	92		$	69
Percent of sales		18.1	%		15.4	%

Commercial Systems operating earnings increased 33 percent to $92 million, or 18.1 percent of sales, for the three months ended March 31, 2011 compared to operating earnings of $69 million, or 15.4 percent of sales, for the three months ended March 31, 2010. The $23 million increase in Commercial Systems operating earnings was primarily due to the following:

· The $58 million increase in sales discussed in the Commercial Systems sales section above resulted in a $24 million increase to costs and incremental operating earnings of $34 million.

· This was partially offset by an $11 million reduction in operating earnings primarily attributable to the combined impact of an increase in selling, general and administrative expense, higher company-funded R&D expense and additional employee incentive compensation costs, partially offset by lower pension expenses as discussed in the Retirement Plans section below.

The increase in Commercial Systems operating earnings as a percent of sales during the three months ended March 31, 2011 compared to the same period one year ago is primarily due to incremental earnings from higher sales and lower pension expense, partially offset by higher selling, general and administrative expense, increased company-funded R&D expense and the additional employee incentive compensation costs explained above.

General Corporate, Net

General corporate expenses that are not allocated to our business segments are included in general corporate, net, which is summarized as follows:

	Three Months Ended
	March 31
(dollars in millions)	2011		2010
General corporate, net	$	12	$	13

General corporate, net was relatively flat during the three months ended March 31, 2011 compared to the three months ended March 31, 2010.

Six Months Ended March 31, 2011 and 2010

Sales

	Six Months Ended
	March 31
(dollars in millions)	2011			2010
Total sales	$	2,333		$	2,169
Percent increase		8	%

Total sales for the six months ended March 31, 2011 increased 8 percent to $2,333 million compared to the six months ended March 31, 2010, due to a $107 million increase in Commercial Systems sales and $57 million increase in Government Systems sales. Incremental sales from the December 2009 acquisition of Air Routing contributed $11 million, or about 1 percentage point of revenue growth. See the following Government Systems and Commercial Systems Financial Results sections for further discussion of sales for the six months ended March 31, 2011 and 2010.

Cost of Sales

	Six Months Ended
	March 31
(dollars in millions)	2011			2010
Total cost of sales	$	1,665		$	1,562
Percent of total sales		71.4	%		72.0	%

Total cost of sales for the six months ended March 31, 2011 increased $103 million, or 7 percent, from the same period of 2010, primarily due to the following:

· A $91 million increase resulted from the $153 million of organic sales growth discussed in the Commercial Systems and Government Systems Financial Results sections below.

· A $22 million increase attributable to higher employee incentive compensation expenses. Employee incentive compensation expense included within cost of sales was $33 million and $11 million for the six months ended March 31, 2011 and 2010, respectively.

· Incremental cost of sales from the Air Routing acquisition of $6 million.

· The above items are partially offset by a $16 million reduction to cost of sales attributable to lower defined benefit pension expense. As discussed in the Retirement Plans section below, the reduction in pension expense was primarily due to a change in the period of time over which actuarial gains and losses are amortized. For the six months ended March 31, 2011, pension income reduced cost of sales by $9 million, compared to $7 million of pension expense during the same period last year.

R&D expense is included as a component of cost of sales and is summarized as follows:

	Six Months Ended
	March 31
(dollars in millions)	2011			2010
Customer-funded:
Government Systems	$	226		$	210
Commercial Systems		39			38

Total company-funded		167			167
Total research and development expense		432			415
Percent of total sales		18.5	%		19.1	%

27

Total R&D expense for the six months ended March 31, 2011 increased $17 million, or 4 percent, from the same period last year, primarily attributable to an increase in customer-funded R&D expense within Government Systems resulting from higher development effort on the CRIIS program and other special mission and tanker transport applications.

Selling, General and Administrative Expenses

	Six Months Ended
	March 31
(dollars in millions)	2011			2010
Selling, general and administrative expenses	$	260		$	228

Total SG&A expenses increased $32 million, or 14 percent, for the six months ended March 31, 2011 compared to the same period of 2010, primarily due to the following:

· $15 million from higher employee incentive compensation costs and merit pay increases.

· A $10 million increase resulting from the pursuit of international business opportunities and our ongoing global expansion as we opened new offices in Paris, China and the Middle East.

· $3 million of incremental SG&A expense from the Air Routing acquisition within Commercial Systems.

Net Income and Diluted Earnings Per Share

	Six Months Ended
	March 31
(dollars in millions, except per share amounts)	2011			2010
Net income	$	301		$	269
Net income as a percent of sales		12.9	%		12.4	%
Diluted earnings per share	$	1.92		$	1.69

Net income for the six months ended March 31, 2011 increased 12 percent to $301 million, or 12.9 percent of sales, from net income of $269 million, or 12.4 percent of sales, for the six months ended March 31, 2010. Diluted earnings per share increased 14 percent to $1.92 for the six months ended March 31, 2011 compared to $1.69 for the six months ended March 31, 2010. The increase in net income and diluted earnings per share was primarily the result of higher earnings from Commercial Systems as discussed in the Commercial Systems Financial Results section below. The increase in earnings per share was greater than the increase in net income due to the positive impact of our share repurchase program.

Government Systems Financial Results

Government Systems Sales

The following table presents Government Systems sales by product category:

	Six Months Ended
	March 31
(dollars in millions)	2011			2010
Airborne solutions	$	935		$	865
Surface solutions		431			444
Total	$	1,366		$	1,309
Percent increase		4	%

Airborne solutions sales increased $70 million, or 8 percent, for the six months ended March 31, 2011 compared to the same period in the prior year, primarily due to the following:

· A $51 million increase from rotary wing avionics sales on various platforms.

28

· A $39 million increase comprised of development effort on the CRIIS program, higher revenues related to low-rate initial production for an E-6 special mission aircraft program and higher simulation and training revenues for the E-2 aircraft.

· The above items were partially offset by a $25 million reduction in sales from the KC-135 Global Air Traffic Management program which is expected to complete this year.

Surface solutions sales decreased $13 million, or 3 percent, for the six months ended March 31, 2011 compared to the same period in the prior year due to the following:

· A $36 million reduction in revenue resulting from a recently completed satellite communication upgrade program.

· Partially offset by a $20 million increase to revenue resulting from a program to provide transportable cellular capabilities in Afghanistan.

Government Systems Segment Operating Earnings

	Six Months Ended
	March 31
(dollars in millions)	2011			2010
Segment operating earnings	$	281		$	284
Percent of sales		20.6	%		21.7	%

Government Systems operating earnings decreased $3 million to $281 million, or 20.6 percent of sales, for the six months ended March 31, 2011 compared to operating earnings of $284 million, or 21.7 percent of sales, for the same period one year ago. The $3 million decrease in Government Systems operating earnings was primarily due to the following:

· A $12 million reduction in operating earnings attributable to the combined impact of higher employee incentive compensation costs and a decrease in pension expense discussed in the Retirement Plans section below.

· Partially offset by a $4 million benefit to operating earnings resulting from lower company-funded R&D expense, as explained in the Cost of Sales section above.

· In addition, the $57 million increase in sales discussed in the Government Systems sales section above resulted in a $52 million increase to costs and incremental operating earnings of $5 million. The higher costs primarily resulted from a lower margin mix of customer-funded development programs.

The decline in Government Systems operating earnings as a percent of sales during the six months ended March 31, 2011 compared to the same period last year was primarily due to higher employee incentive compensation costs and an unfavorable change in contract mix related to the lower margin development revenues. This was partially offset by a reduction in pension expense and lower company-funded R&D.

The $39 million increase in Commercial Systems operating earnings was primarily due to the following:

· A $107 million increase in sales discussed in the Commercial Systems sales section above which resulted in a $51 million increase to costs and incremental operating earnings of $56 million.

· This was partially offset by a $17 million reduction in operating earnings primarily attributable to the combined impact of an increase in selling, general and administrative expense, an increase in company-funded R&D expense and higher employee incentive compensation costs, partially offset by lower pension expenses as discussed in the Retirement Plans section below.

The increase in Commercial Systems operating earnings as a percent of sales during the six months ended March 31, 2011 compared to the same period one year ago was primarily due to incremental earnings from higher sales and lower pension expense, partially offset by higher selling, general and administrative expense, higher employee incentive compensation costs and an increase in company-funded R&D expense as explained above.

Pension Benefits

In 2003, we amended our U.S. qualified and non-qualified pension plans (the Pension Amendment) covering all salary and hourly employees not covered by collective bargaining agreements to discontinue benefit accruals for salary increases and services rendered after September 30, 2006. Concurrently, we replaced this benefit by supplementing our existing defined contribution savings plan to include an additional Company contribution effective October 1, 2006. We believe this benefit structure achieves our objective of providing benefits that are valued by our employees and provides more consistency and predictability in estimating future costs and funding requirements over the long term.

31

For the full year 2011, defined benefit pension plan expense will decrease by approximately $42 million to $16 million of income, compared to $26 million of expense for the full year 2010. The decrease is primarily due to a change in the period of time over which actuarial gains and losses are amortized.

In 2010, actuarial gains and losses in excess of 10 percent of the greater of the market-related value of plan assets or the projected benefit obligation (the corridor) were amortized on a straight-line basis over the average remaining service period of active participants, which was approximately 11 years. Beginning in 2011, the amortization of such gains and losses is over the expected future lifetime of inactive participants, which is approximately 28 years. The extension of the amortization period was required because almost all of the plan's participants are now inactive due to the pension freeze that went into effect in 2006 for most employees. This change in amortization period is driving the reduction in pension expense for 2011.

Our objective with respect to the funding of our pension plans is to provide adequate assets for the payment of future benefits. Pursuant to this objective, we will fund our pension plans as required by governmental regulations and may consider discretionary contributions as conditions warrant. We believe our strong financial position continues to provide us the opportunity to make contributions to our pension fund without inhibiting our ability to pursue strategic investments.

In January 2011 we made a $100 million contribution to our U.S. qualified pension plan. We are not required by governmental regulations to make any additional contributions to the U.S. qualified pension plan in 2011. Any additional future contributions necessary to satisfy the minimum statutory funding requirements are dependent upon actual plan asset returns and interest rates. We may elect to make additional discretionary contributions during 2011 to further improve the funded status of this plan. Contributions to the non-U.S. plans and the U.S. non-qualified plan are expected to total $13 million in 2011. We made contributions to the non-U.S. plans and the U.S. non-qualified pension plan of $7 million for the six months ended March 31, 2011, compared to $7 million for the six months ended March 31, 2010.

Our pension expense (income) is impacted by the market performance of our pension plan assets, our expected long-term return on plan assets and the discount rates used to determine our pension obligations. If our pension plan assets do not achieve positive rates of return consistent with our long-term asset return assumptions or if discount rates trend down, we may experience unfavorable changes in our pension expense (income) and could be required to make significant contributions to our U.S. qualified pension plan. We did elect funding relief under recently passed U.S. pension funding legislation. The relief generally should provide flexibility in future minimum cash contributions to the U.S. qualified pension plan. While we believe the actions taken under the Pension Amendment have had a positive effect on pension expense (income) and future funding requirements, our plan assets and discount rates are significantly impacted by changes in the financial markets.

Other Retirement Benefits

We expect other retirement benefits expense of approximately $10 million in 2011 compared to the full year 2010 expense of $5 million.

Income Taxes

At the end of each interim reporting period we make an estimate of the annual effective income tax rate. Tax items included in the annual effective income tax rate are pro-rated for the full year and tax items discrete to a specific quarter are included in the effective income tax rate for that quarter. The estimate used in providing for income taxes on a year-to-date basis may change in subsequent interim periods. The difference between our effective income tax rate and the statutory income tax rate is primarily the result of the tax benefits derived from the Federal Research and Development Tax Credit (Federal R&D Tax Credit) and certain state research and development tax credits, which provide tax benefits on certain incremental R&D expenditures, and the Domestic Manufacturing Deduction (DMD), which provides a tax benefit on U.S. based manufacturing.

During the three months ended March 31, 2011 and 2010, our effective income tax rate was 31.5 percent and 24.5 percent, respectively. The lower effective income tax rate for the three months ended March 31, 2010 was primarily due to a favorable adjustment resulting from the IRS completing its examination of the taxable years ended September 30, 2006 and 2007. The prior year favorable adjustment resulted in a benefit to the 2010 effective income tax rate of about 10 percent. This prior year benefit was partially offset by an increase to the  2010 effective income tax rate of about 2 percent related to differences in the availability of the Federal R&D Tax Credit, which expired on December 31, 2009.

32

During the six months ended March 31, 2011 and 2010, our effective income tax rate was 26.9 percent and 28.6 percent, respectively. The lower effective income tax rate for the six months ended March 31, 2011 was primarily due to the differences in the availability of the Federal R&D Tax Credit, which expired on December 31, 2009, and the increased tax benefit of the DMD for fiscal year 2011, as compared to the DMD tax benefit for fiscal year 2010 which was two-thirds of the full benefit.

On December 17, 2010, the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010, was enacted, which retroactively reinstated and extended the Federal R&D Tax Credit from January 1, 2010 to December 31, 2011. The retroactive benefit for the previously expired period from January 1, 2010 to September 30, 2010 was recognized and lowered the Company’s effective income tax rate by about 4 percent for the six months ended March 31, 2011. Additionally, the annual effective income tax rate applied to the six months ended March 31, 2011 reflects twelve months of benefit from the Federal R&D Tax Credit whereas the annual effective income tax rate applied to the six months ended March 31, 2010 reflected only three months of benefit.

For fiscal year 2011, our effective income tax rate is projected to be in the range of 28.0 percent to 29.0 percent.

Outlook

The following table is a complete summary of our updated fiscal year 2011 financial guidance:

· total sales in the range of $4.8 billion to $5.0 billion

· diluted earnings per share in the range of $3.90 to $4.10

· cash provided by operating activities in the range of $650 million to $750 million

· capital expenditures of about $150 million

· total company and customer-funded R&D expenditures in the range of $900 million to $950 million, or about 19 percent of sales

FINANCIAL CONDITION AND LIQUIDITY

Cash Flow Summary

Operating Activities

	Six Months Ended
	March 31
(in millions)	2011		2010
Cash provided by operating activities	$	127	$	280

The $153 million decrease in cash provided by operating activities during the six months ended March 31, 2011 compared to the same period last year was primarily due to the following:

· Payments for inventory and other operating costs increased $100 million to $1,923 million in 2011 compared to $1,823 million in 2010. The increase was primarily due to higher costs associated with organic sales growth in 2011 as discussed in the Results of Operations section above, as well as higher pre-production engineering effort and inventory purchases for anticipated production volume.

· Payments for incentive pay increased $71 million in 2011 compared to 2010. Incentive pay is expensed in the year it is incurred and paid in the first fiscal quarter of the following year. During the first six months of 2011, $71 million was paid for employee incentive pay costs incurred during 2010. For the full fiscal year 2009, no incentive pay costs were incurred; accordingly, there was no 2010 payment for incentive pay.

· Offset by cash receipts from customers which increased $17 million to $2,271 million in 2011 compared to $2,254 million in 2010, primarily due to the higher sales in 2011 discussed in the Results of Operations section above.

Investing Activities

	Six Months Ended
	March 31
(in millions)	2011			2010
Cash used for investing activities	$	(64	)	$	(156	)

The decrease in cash used for investing activities during the six months ended March 31, 2011 compared to the same period last year was primarily due to the following:

· In the first six months of 2011 we acquired Blue Ridge Simulation for $6 million and CTA for $11 million, compared to the 2010 acquisition of Air Routing for $91 million.

· During the second quarter of 2011 we received proceeds of $18 million from the sale of short-term investments at a non-U.S. subsidiary.

Financing Activities

	Six Months Ended
	March 31
(in millions)	2011			2010
Cash used for financing activities	$	(266	)	$	(113	)

The increase in cash used for financing activities during the six months ended March 31, 2011 compared to the same period last year was primarily due to the following:

· $145 million of the increase is due to higher purchases of treasury stock. During the six months ended March 31, 2011, we repurchased $211 million of common stock compared to $66 million during the same period last year.

· The proceeds received from the exercise of stock options declined $9 million in 2011 compared to 2010. During the six months ended March 31, 2011 we received $12 million in proceeds from the exercise of stock options compared to $21 million during the same period last year.

Financial Condition and Liquidity

We have historically maintained a financial structure characterized by conservative levels of debt outstanding that enables us sufficient access to credit markets. When combined with our ability to generate strong levels of cash flow from our operations, this capital structure provides the strength and flexibility necessary to pursue strategic growth opportunities and to return value to our shareowners. A comparison of key elements of our financial condition as of March 31, 2011 and September 30, 2010 are as follows:

	March 31,			September 30,
(in millions)	2011			2010
Cash and cash equivalents	$	236		$	435
Short-term investments		0			20
Short-term debt		(28	)		(24	)
Long-term debt, net		(509	)		(525	)
Net debt (1)	$	(301	)	$	(94	)
Total equity	$	1,577		$	1,486
Debt to total capitalization (2)		25	%		27	%
Net debt to total capitalization (3)		16	%		6	%

(1) Calculated as total of short-term and long-term debt, net (Total Debt), less cash and cash equivalents and short-term investments

(2)  Calculated as Total Debt divided by the sum of Total Debt plus Total equity

(3)  Calculated as Net debt divided by the sum of Net debt plus Total equity

34

We primarily fund our contractual obligations, capital expenditures, small to medium sized acquisitions, dividends and share repurchases from cash generated from operating activities. Due to the fluctuations of cash flows, we supplement our internally generated cash flow from time to time by issuing short-term commercial paper. Under our commercial paper program, we may sell up to $850 million face amount of unsecured short-term promissory notes in the commercial paper market. The commercial paper notes have maturities of not more than 364 days from the date of issuance. At March 31, 2011, short-term commercial paper borrowings outstanding were $15 million with a weighted average interest rate and maturity period of 0.21 percent and 3 days, respectively. At September 30, 2010, there were no outstanding short-term commercial paper borrowings. As discussed in Note 22 of the Notes to Condensed Consolidated Financial Statements in Item 1, we entered into an agreement with Bombardier in April 2011 (subsequent to our March 31, 2011 quarter end) to provide them $237 million of cash that will be repaid to us in full within 60 days of our successful completion of certain regulatory approvals with the U.S. Federal Aviation Authority. We successfully met these conditions on April 20, 2011 and, as a result, the repayment by Bombardier is expected to take place on or before June 20, 2011. We funded the payment to Bombardier by issuing short term commercial paper borrowings in April 2011.

In the event our access to the commercial paper markets is impaired, we have access to an $850 million Revolving Credit Facility through a network of banks that matures in 2012, with options to further extend the term for up to two one-year periods and/or increase the aggregate principal amount up to $1.2 billion. These options are subject to the approval of the lenders. Our only financial covenant under the Revolving Credit Facility requires that we maintain a consolidated debt to total capitalization ratio of not greater than 60 percent, excluding the accumulated other comprehensive loss equity impact related to defined benefit retirement plans. Our debt to total capitalization ratio at March 31, 2011 based on this financial covenant was 16 percent. We had no borrowings at March 31, 2011 under our Revolving Credit Facility.

In addition, alternative sources of liquidity could include funds available from the issuance of equity securities, debt securities and potential asset securitization strategies. We have a shelf registration statement filed with the Securities and Exchange Commission pursuant to which we can publicly offer and sell securities from time to time. This shelf registration covers an unlimited amount of debt securities, common stock and preferred stock or warrants that may be offered in one or more offerings on terms to be determined at the time of sale. To date, we have not raised capital through the issuance of equity securities as we prefer to use debt financing to lower our overall cost of capital and increase our return on shareowners' equity.

Credit ratings are a significant factor in determining our ability to access short-term and long-term financing as well as the cost of such financing in terms of interest rates. Our strong credit ratings have enabled continued access to both short and long-term credit markets. If our credit ratings were to be adjusted downward by the rating agencies, the implications of such actions could include impairment or elimination of our access to credit markets and an increase in the cost of borrowing. The following is a summary of our credit ratings as of March 31, 2011:

Credit Rating Agency	Short-Term Rating	Long-Term Rating	Outlook
Fitch Ratings	F1	A	Stable
Moody’s Investors Service	P-1	A1	Stable
Standard & Poor’s	A-1	A	Stable

We were in compliance with all debt covenants at March 31, 2011 and September 30, 2010.

These forward-looking statements are made only as of the date hereof.

Item 3.     Quantitative and Qualitative Disclosures about Market Risk

Interest Rate Risk

In addition to using cash provided by normal operating activities, we utilize a combination of short-term and long-term debt to finance operations. Our operating results and cash flows are exposed to changes in interest rates that could adversely affect the amount of interest expense incurred and paid on debt obligations in any given period. In addition, changes in interest rates can affect the fair value of our debt obligations. Such changes in fair value are only relevant to the extent these debt obligations are settled prior to maturity. We manage our exposure to interest rate risk by maintaining an appropriate mix of fixed and variable rate debt and when considered necessary, we may employ financial instruments in the form of interest rate swaps to help meet this objective.

At March 31, 2011, we had $200 million of 4.75 percent fixed rate long-term debt obligations outstanding with a carrying value of $200 million and a fair value of $217 million. In 2004 we converted $100 million of this fixed rate debt to floating rate debt bearing interest at six-month LIBOR less .075 percent by executing “receive fixed, pay variable” interest rate swap contracts. At March 31, 2011, we also had $300 million of 5.25 percent fixed rate long-term debt obligations outstanding with a carrying value of $299 million and a fair value of $324 million. In January 2010 we converted $150 million of this fixed rate debt to floating rate debt based on six-month LIBOR plus 1.235 percent.

A hypothetical 10 percent increase or decrease in average market interest rates would have decreased or increased the fair value of our long-term fixed rate debt, exclusive of the effects of the interest rate swap contracts, by $8 million and $8 million, respectively. The fair value of the $250 million notional value of interest rate swap contracts was a $10 million net asset at March 31, 2011. A hypothetical 10 percent increase or decrease in average market interest rates would decrease or increase the fair value of our interest rate swap contracts by $1 million and $2 million, respectively. At March 31, 2011, we also had $13 million of variable rate short-term debt outstanding. Our results of operations are affected by changes in market interest rates related to variable rate debt. Inclusive of the effect of the interest rate swaps, a hypothetical 10 percent increase or decrease in average market interest rates would not have a material effect on our operations or cash flows. For more information related to outstanding debt obligations and derivative financial instruments, see Notes 10, 16 and 17 in the Condensed Consolidated Financial Statements.

36

Foreign Currency Risk

We transact business in various foreign currencies which subjects our cash flows and earnings to exposure related to changes to foreign currency exchange rates. We attempt to manage this exposure through operational strategies and the use of foreign currency forward exchange contracts (foreign currency contracts). All foreign currency contracts are executed with banks we believe to be creditworthy and are denominated in currencies of major industrial countries. The majority of our non-functional currency firm and anticipated receivables and payables are hedged using foreign currency contracts. It is our policy not to manage exposure to net investments in non-U.S. subsidiaries or enter into derivative financial instruments for speculative purposes. Notional amounts of outstanding foreign currency forward exchange contracts were $427 million and $404 million at March 31, 2011 and September 30, 2010, respectively. Notional amounts are stated in U.S. dollar equivalents at spot exchange rates at the respective dates. Principal currencies that are hedged include the European euro and British pound sterling. The duration of foreign currency contracts is generally five years or less. The net fair value of these foreign currency contracts was a net asset of $2 million and $1 million at March 31, 2011 and September 30, 2010, respectively. A 10 percent increase or decrease in the value of the U.S. dollar against all currencies would decrease or increase the fair value of our foreign currency contracts at March 31, 2011 by $5 million.

Item 4.     Controls and Procedures

As required by Rule 13a-15(b) under the Securities Exchange Act of 1934, we carried out an evaluation of the effectiveness, as of March 31 2011, of the design and operation of our disclosure controls and procedures. This evaluation was carried out under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures are effective as of March 31, 2011 to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Securities Exchange Act of 1934 is accumulated and communicated to the issuer’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

There were no changes in our internal control over financial reporting (as defined in Exchange Act Rule 13a-15(f)) that occurred during our last fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
