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, December 31 and September 30 are utilized consistently throughout these financial statements and notes to represent the period end date.

The Company has one consolidated subsidiary with income attributable to a noncontrolling interest. The net income and comprehensive income attributable to the noncontrolling interest is insignificant.

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, 2012.

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 months ended December 31, 2012 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.

During the second quarter of fiscal 2012, the Company determined that certain product sales had erroneously been presented as service sales in previously issued financial statements. With the correction, service sales are less than ten percent of total sales for all periods presented. Accordingly, service and product sales are no longer separately presented. This change did not impact previously reported total revenues, total cost of sales, or net income, nor did it have any effect on the Company's financial position or cash flows for any prior periods.

2. Recently Issued Accounting Standards

In June 2011, the Financial Accounting Standards Board (FASB) amended requirements for the presentation of other comprehensive income (OCI), requiring presentation of comprehensive income in either a single, continuous statement of comprehensive income or on separate but consecutive statements, the statement of operations and the statement of OCI. The amendment became effective for the Company in the first quarter of 2013 and the Company has reported OCI as a separate but consecutive statement. There was no impact to the Company's financial position, results of operations or cash flows as a result of this amendment.

3. Receivables, Net

Receivables, net are summarized as follows:

(in millions)	December 31, 2012			September 30, 2012
Billed	$	685		$	810
Unbilled	396			366
Less progress payments	(164		)	(169		)
Total	917			1,007
Less allowance for doubtful accounts	(11		)	(36		)
Receivables, net	$	906		$	971

Receivables expected to be collected beyond the next twelve months are classified as long-term and are included within Other Assets. Total net receivables due from the U.S. Government, including the Department of Defense, both directly and indirectly through subcontracts, were $244 million at December 31, 2012 and $284 million at September 30, 2012. U.S. Government unbilled receivables, net of progress payments, were $106 million and $93 million at December 31, 2012 and September 30, 2012, 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.

During the three months ended December 31, 2012, the Company completed its negotiations with Hawker Beechcraft, Inc., subject to bankruptcy court approval, for certain outstanding receivable balances related to their Chapter 11 bankruptcy filing. No further adjustments to the estimated bad debt charges were required.

4. Inventories, Net

Inventories, net are summarized as follows:

(in millions)	December 31, 2012			September 30, 2012
Finished goods	$	190		$	168
Work in process	268			254
Raw materials, parts and supplies	348			343
Less progress payments	(8		)	(2		)
Total	798			763
Pre-production engineering costs	605			569
Inventories, net	$	1,403		$	1,332

The Company defers certain pre-production engineering costs during the development phase of a 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 using a units-of-delivery method, up to 15 years. This amortization expense is included as a component of cost of sales. Amortization is based on the Company’s expectation of delivery rates on a program-by-program basis and begins when the Company starts recognizing revenue as the Company delivers equipment for the program. 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.

Anticipated annual amortization expense for pre-production engineering costs is as follows:

(in millions)	2013		2014		2015		2016		2017		Thereafter
Anticipated amortization expense	$	29	$	44	$	64	$	75	$	79	$	319

Amortization expense for pre-production engineering costs for the three months ended December 31, 2012 was $5 million compared with $3 million for the three months ended December 31, 2011. During the fourth quarter of 2012, the Company reclassified this amortization on the Condensed Consolidated Statement of Cash Flows from changes in Inventories to Amortization of intangible assets and pre-production engineering costs for all periods presented. As of December 31, 2012, the weighted average amortization period remaining for pre-production engineering costs included in Inventories, net was approximately 10 years.

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 are amortized using a units-of-delivery method over the period the Company has received a contractually enforceable right related to the incentives, up to 15 years. Amortization is based on the Company’s expectation of delivery rates on a program-by-program basis. Amortization begins when the Company starts recognizing revenue as the Company delivers equipment for the program. 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. As of December 31, 2012, the weighted average amortization period remaining for up-front sales incentives was approximately 9 years.

Anticipated annual amortization expense for intangible assets is as follows:

(in millions)	2013		2014		2015		2016		2017		Thereafter
Anticipated amortization expense for up-front sales incentives	$	9	$	13	$	23	$	27	$	29	$	95
Anticipated amortization expense for all other intangible assets	22		19		15		12		11		24
Total	$	31	$	32	$	38	$	39	$	40	$	119

Amortization expense for intangible assets for the three months ended December 31, 2012 was $8 million compared to $10 million for the three months ended December 31, 2011.

The Company reviews Intangible Assets for impairment at least annually, or whenever potential indicators of impairment exist.

7. Other Assets

Other assets are summarized as follows:

(in millions)	December 31, 2012		September 30, 2012
Long-term receivables	$	34	$	34
Investments in equity affiliates	21		19
Exchange and rental assets (net of accumulated depreciation of $89 at December 31, 2012 and $94 at September 30, 2012)	51		51
Other	120		124
Other assets	$	226	$	228

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 $33 million for the three months ended December 31, 2012 and $28 million for the three months ended December 31, 2011. The deferred portion of profit generated from sales to equity affiliates was $1 million and $3 million at December 31, 2012 and September 30, 2012, respectively.

Exchange and Rental Assets

Exchange and rental assets consist primarily of Company products that are either loaned or rented to customers on a short-term basis in connection with warranty and other service related activities. These assets are recorded at acquisition or production cost and depreciated using the straight-line method over their estimated lives up to 15 years. Depreciation expense for exchange and rental assets was $2 million and $2 million for the three months ended December 31, 2012 and December 31, 2011, respectively.

Current portion of long-term debt	200		—
Fair value swap adjustment (Notes 13 and 14)	4		—
Short-term debt	$	549	$	—

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 0.075 percent. See Notes 13 and 14 for additional information relating to the interest rate swap contracts. The 2013 Notes mature within one year and as of December 31, 2012, are included in the Condensed Consolidated Statement of Financial Position net of any unamortized discount within the caption Short-term Debt.

The 2013 Notes 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. The Company was in compliance with all debt covenants at December 31, 2012 and September 30, 2012.

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 December 31, 2012, short-term commercial paper borrowings outstanding were $345 million with a weighted-average interest rate and maturity period of 0.18 percent and 9 days, respectively. At September 30, 2012, there were no outstanding short-term commercial paper borrowings.

Revolving Credit Facilities

On May 26, 2011, the Company entered into an $850 million five-year unsecured revolving credit facility with various banks. 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 30 percent as of December 31, 2012. The credit facility includes 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. The credit facility also contains 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 December 31, 2012 and September 30, 2012, there were no outstanding borrowings under the revolving credit facility.

In addition, short-term credit facilities available to non-U.S. subsidiaries amounted to $57 million as of December 31, 2012, of which $17 million supports commitments in the form of commercial letters of credit. As of December 31, 2012 and September 30, 2012, there were no short-term borrowings outstanding under the Company’s non-U.S. subsidiaries’ credit facilities.

At December 31, 2012 and September 30, 2012, there were no significant commitment fees or compensating balance requirements under any of the Company’s credit facilities.

On November 16, 2011, the Company issued $250 million of 3.10 percent fixed rate unsecured debt due November 15, 2021 (the 2021 Notes). The net proceeds to the Company from the sale of the 2021 Notes, after deducting a $1 million discount and $2 million of debt issuance costs, were $247 million.

On May 6, 2009, the Company issued $300 million of 5.25 percent fixed rate unsecured debt due July 15, 2019 (the 2019 Notes). 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 13 and 14 for additional information relating to the interest rate swap contracts.

The 2021 and 2019 Notes are included in the Condensed Consolidated Statement of Financial Position net of any 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 debt issuance costs and any discounts are amortized over the life of the debt and recorded in Interest expense.

The 2021 and 2019 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. The Company was in compliance with all debt covenants at December 31, 2012 and September 30, 2012.

In fiscal year 2013, the expected long-term rate of return on plan assets for both U.S. Pension Benefits and Other Retirement Benefits was reduced to 8.25 percent compared to 8.75 percent in fiscal year 2012.

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. During the three months ended December 31, 2012, the Company contributed $55 million to its U.S. qualified pension plan. In January 2013, subsequent to the Company's first quarter, the Company made an additional $55 million contribution to its U.S. qualified pension plan. The Company does not expect to make any additional contributions to its U.S. qualified pension plan during 2013. Contributions to the non-U.S. plans and the U.S. non-qualified plan are expected to total $14 million in 2013. For the three months ended December 31, 2012 and 2011, the Company made contributions to the non-U.S. plans and the U.S. non-qualified pension plan of $2 million and $3 million, respectively.

The Company issued awards of equity instruments under the Company's various incentive plans for the three months ended December 31, 2012 and 2011 as follows:

	Options			Performance Shares			Restricted Stock Units
(shares in thousands)	Number Issued	Weighted Average Fair Value		Number Issued	Weighted Average Fair Value		Number Issued	Weighted Average Fair Value

Three months ended December 31, 2011	752.8	$	13.89	190.0	$	55.01	66.1	$	54.89

The maximum number of shares of common stock that can be issued in respect of performance shares granted in 2013 based on the achievement of performance targets for fiscal years 2013 through 2015 is approximately 477,000.

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

	2013 Grants		2012 Grants
Risk-free interest rate	0.3% - 1.7%		0.3% - 2.2%
Expected dividend yield	2.0	%	1.6	%

12. 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 December 31, 2012 and 2011, the effective income tax rate was 29.8 percent and 33.0 percent, respectively.

The effective income tax rate for the three months ended December 31, 2012 was lower than the same period of the prior year primarily due to the recognition of the tax benefit from net operating loss carryovers in the United Kingdom.

On January 2, 2013, subsequent to the first quarter, the American Taxpayer Relief Act of 2012 was enacted which

11

ROCKWELL COLLINS, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(Unaudited)

retroactively reinstated and extended the Federal Research and Development Tax Credit (Federal R&D Tax Credit) from January 1, 2012 to December 31, 2013. As a result, the Company expects its income tax provision for the second quarter of fiscal year 2013 will include a discrete tax benefit that will reduce the annual effective income tax rate by approximately 2 percent for the previously expired period from January 1, 2012 to September 30, 2012.

The Company's U.S. Federal income tax returns for the tax years ended September 30, 2009 and prior have been audited by the Internal Revenue Service (IRS) and are closed to further adjustments. The IRS is currently auditing the Company's returns for the years ended September 30, 2010 and 2011. The Company is also currently under audit in various U.S. state and non-U.S. jurisdictions, which 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 $12 million and $24 million during the three months ended December 31, 2012 and 2011, respectively.

The Company had gross unrecognized tax benefits recorded within Other Liabilities in the Condensed Consolidated Statement of Financial Position of $45 million and $42 million as of December 31, 2012 and September 30, 2012, respectively. The total amounts of unrecognized tax benefits that, if recognized, would affect the effective income tax rate were $25 million and $24 million as of December 31, 2012 and September 30, 2012, respectively. 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 of approximately $0 million to $26 million based on the outcome of tax examinations or as a result of the expiration of various statutes of limitations.

The Company includes interest and penalties related to unrecognized tax benefits in income tax expense. The total amount of interest and penalties recognized within Other Liabilities in the Condensed Consolidated Statement of Financial Position was approximately $2 million and $2 million as of December 31, 2012 and September 30, 2012. 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 $0 million and $0 million for the three months ended December 31, 2012 and 2011.

13. 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.

ROCKWELL COLLINS, INC.

(Unaudited)

The fair value of the Company's financial assets and liabilities measured at fair value on a recurring basis as of December 31, 2012 and September 30, 2012 are as follows:

		December 31, 2012			September 30, 2012
(in millions)	Fair Value Hierarchy	Fair Value Asset (Liability)			Fair Value Asset (Liability)
Deferred compensation plan investments	Level 1	$	45		$	42
Interest rate swap assets	Level 2	29			31
Foreign currency forward exchange contract assets	Level 2	5			7
Foreign currency forward exchange contract liabilities	Level 2	(5		)	(5		)

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 three months ended December 31, 2012 or 2011.

The carrying amounts and fair values of the Company’s financial instruments are as follows:

	Asset (Liability)
	December 31, 2012						September 30, 2012
(in millions)	Carrying Amount			Fair Value			Carrying Amount			Fair Value
Cash and cash equivalents	$	337		$	337		$	335		$	335
Short-term debt	(545		)	(553		)	—			—
Long-term debt	(548		)	(629		)	(748		)	(837		)

The fair value of cash and cash equivalents and the commercial paper portion of the short-term debt approximate their carrying value due to the short-term nature of the instruments and these items are within Level 1 of the fair value hierarchy. Fair value information for the 2013 Notes classified as short-term debt and all long-term debt is within Level 2 of the fair value hierarchy and 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 short-term and 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.

14. 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 0.075 percent.

13

ROCKWELL COLLINS, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(Unaudited)

The Company has designated the 2019 Swap and 2013 Swap (the Swaps) as fair value hedges. The 2013 swap matures within one year and therefore is recorded within Other current assets at a fair value of $4 million offset by a fair value adjustment to Short-term debt (Note 8) of $4 million at December 31, 2012. The 2019 Swap is recorded within Other Assets at a fair value of $25 million, offset by a fair value adjustment to Long-term Debt (Note 8) of $25 million at December 31, 2012. At September 30, 2012, both Swaps were classified as long-term and were recorded within Other Assets at a fair value of $31 million, offset by a fair value adjustment to Long-term Debt (Note 8) of $31 million. 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 December 31, 2012 and September 30, 2012, the Company had outstanding foreign currency forward exchange contracts with notional amounts of $359 million and $393 million, respectively. These notional values consist primarily of contracts for the European euro, British pound sterling and Japanese yen, and are stated in U.S. dollar equivalents at spot exchange rates at the respective dates.

Fair Value of Derivative Instruments

Fair values of derivative instruments in the Condensed Consolidated Statement of Financial Position as of December 31, 2012 and September 30, 2012 are as follows:

		Asset Derivatives

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 December 31, 2012 and September 30, 2012, $0 million and $0 million, respectively, of foreign currency forward exchange contracts, classified within Other current assets, were not designated as hedging instruments.

There was no significant impact to the Company’s earnings related to the ineffective portion of any hedging instruments during the three months ended December 31, 2012. 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 months ended December 31, 2012.

The Company did not have any hedges with credit-risk-related contingent features or that required the posting of collateral as of December 31, 2012. The cash flows from derivative contracts are recorded in operating activities in the Condensed Consolidated Statement of Cash Flows.

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 $2 million of net gains into earnings over the next 12 months. The maximum duration of a foreign currency cash flow hedge contract at December 31, 2012 was 91 months.

15. 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 December 31, 2012, the outstanding loan balance was approximately $5 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 December 31, 2012, 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 December 31, 2012 were $73 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.

16

ROCKWELL COLLINS, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(Unaudited)

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.

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.

16. 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 December 31, 2012, 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 $12 million. Environmental reserves for this site were $6 million and $6 million as of December 31, 2012 and September 30, 2012, respectively, 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 effect on the Company’s business or financial position, but could possibly be significant to the results of operations or cash flows of any one quarter.

17. Legal Matters and Other Uncertainties

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 effect on the Company's business or financial position, but could possibly be significant to the results of operations or cash flows of any one quarter.

The Company depends to a large degree on U.S. Government spending, as a significant portion of the Company's sales are derived from U.S. Government contracts, both directly and indirectly through subcontracts. In August 2011, Congress enacted the Budget Control Act of 2011 (BCA) which imposes spending caps and certain reductions in security spending over a ten-year period through 2021. Absent additional Congressional action, further budget cuts, referred to as sequestration, will be implemented in March 2013. Future reductions in U.S. Government security spending could have a significant adverse impact on the financial results of the Company's Government Systems operating segment. While management believes the Company's product offerings are well positioned to meet the needs of its customer base, any material deterioration in the economic and environmental factors that impact the aerospace and defense industries could have a material adverse effect on the Company's results of operations, financial position or cash flows.

18. Restructuring and Asset Impairment Charges, Net

During the year ended September 30, 2012, the Company recorded corporate restructuring and asset impairment charges, net totaling $58 million. Included in this charge was $35 million related to employee severance costs, primarily resulting from decisions to realign the Company's European organizational structure to better position the business for long-term growth and to adjust the size of our workforce in preparation for the sequestration impacts on the U.S. defense budgets. During the three months ended December 31, 2012, the Company made cash severance payments of $3 million. As of December 31, 2012, $28 million of employee severance costs related to this action remains to be paid in future periods.

During the year ended September 30, 2011, the Company recorded restructuring and asset impairment charges totaling $27 million. This amount was primarily comprised of non-cash asset impairment charges of $11 million, employee severance of $7 million, and $9 million of other costs, primarily attributable to a lease termination. The charges related to decisions to implement certain business realignment and facility rationalization actions in response to global economic factors that have negatively impacted the Company's Government Systems segment. All actions have been completed except for a remaining lease termination payment of $3 million which will be paid in future periods.

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

OVERVIEW AND OUTLOOK

Business Overview

We have a diversified and balanced business, serving both commercial and government markets. Revenues decreased 3 percent during the first quarter of fiscal year 2013 as the downturn in U.S. defense spending contributed to a 6 percent reduction in sales for Government Systems that was partially offset by a 1 percent increase in sales for our Commercial Systems business. Despite the challenging defense environment, we maintained strong total segment operating margins at 20.1 percent of sales, comparable to the 19.9 percent total segment operating margin achieved in the same period last year. Earnings per share increased 9 percent from higher net income and the favorable impact of our active share repurchase program. During the first quarter of 2013, we repurchased 6 million shares of common stock for a total cost of $333 million.

In Commercial Systems, market conditions remain relatively unchanged from when we originally provided our fiscal year 2013 earnings guidance on September 21, 2012. We see continued strength across the air transport original equipment manufacturer (OEM) markets as sales are expected to benefit from anticipated production rate increases for the Boeing 787 and other legacy Boeing and Airbus aircraft. In addition, we further strengthened our long-term relationship with Boeing this quarter as we were selected to provide large-format flight displays as standard equipment on the 737 MAX flight deck. We continue to expect modest growth in business and regional OEM sales with additional growth in aftermarket revenues concentrated into the latter part of our fiscal 2013 from anticipated mandate and retrofit activities.

In Government Systems, the legislation passed by Congress in January 2013 to temporarily delay the impact of sequestration budget cuts by two months did not change our outlook for fiscal year 2013. Absent additional Congressional action, the sequestration budget cuts will be implemented in March 2013. Our fiscal year 2013 financial guidance already incorporates the impact of sequestration.

On January 2, 2013, the American Taxpayer Relief Act of 2012 was enacted which retroactively reinstated and extended the Federal Research and Development Tax Credit from January 1, 2012 to December 31, 2013. This favorable tax credit had previously expired on December 31, 2011. As a result of this change in legislation, we now expect our effective income tax rate for 2013 to be about 27 percent. We expect this Federal R&D tax credit extension to drive an approximate $0.15 cent net improvement to our fiscal year 2013 earnings per share guidance range, as the benefit from lower income taxes will be partially offset by higher employee incentive pay costs.

The following table is an updated summary of our fiscal year 2013 financial guidance:

Ÿ	total sales	$4.6 billion to $4.7 billion
Ÿ	diluted earnings per share	$4.45 to $4.65 (updated from $4.30 to $4.50)
Ÿ	cash provided by operating activities	$500 million to $600 million
Ÿ	capital expenditures	about $140 million
Ÿ	total research and development investment (1)	about $1.0 billion

(1) Total research and development investment is comprised of company and customer-funded R&D expenditures and the net increase in pre-production engineering costs capitalized within Inventory.

RESULTS OF OPERATIONS

The following management discussion and analysis is based on financial results for the three months ended December 31, 2012 and 2011 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 December 31, 2012 and 2011

Sales

	Three Months Ended
	December 31
(dollars in millions)	2012			2011
Total sales	$	1,062		$	1,094
Percent (decrease)	(3		)%

Total sales for the three months ended December 31, 2012 decreased $32 million compared to the three months ended December 31, 2011 due to a $37 million reduction in Government Systems sales, partially offset by a $5 million increase in Commercial Systems sales. See the following Government Systems and Commercial Systems Financial Results sections for further discussion of sales.

Cost of Sales

	Three Months Ended
	December 31
(dollars in millions)	2012			2011
Total cost of sales	$	750		$	774
Percent of total sales	70.6		%	70.7		%

Cost of sales consists of 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 December 31, 2012 decreased $24 million, or 3 percent, from the same period last year, primarily due to the $32 million reduction in sales volume and the $9 million reduction in company-funded R&D cost described below.

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

	Three Months Ended
	December 31
(dollars in millions)	2012			2011
Customer-funded:
Government Systems	$	98		$	108
Commercial Systems	22			21
Total customer-funded	120			129
Company-funded:
Government Systems	17			21
Commercial Systems	54			59
Total company-funded	71			80
Total research and development expense	$	191		$	209
Percent of total sales	18.0		%	19.1		%

Customer-funded R&D expenditures are incurred pursuant to contractual arrangements and are typically accounted for as contract costs within cost of sales with the reimbursement accounted for as a sale in accordance with the percentage-of-completion-method of accounting. Company-funded R&D expenditures relate to internally funded effort towards the development of new products and the improvement of existing products and these costs are expensed as incurred. In addition to the R&D expenditures shown in the table above, we defer the cost of certain pre-production engineering effort incurred during the development phase of programs when the customer has provided us a long-term supply arrangement and a contractual guarantee for reimbursement, as explained in Note 4 of the Notes to Condensed Consolidated Financial Statements. Pre-production engineering costs are then amortized over their useful lives, and the amortization cost is included within customer-funded R&D expense. This amortization totaled $5 million and $3 million for the three months ended December 31, 2012 and 2011, respectively.

Total R&D expense for the three months ended December 31, 2012 decreased $18 million from the same period last year. Customer-funded R&D decreased $9 million and was primarily due to a decline in spending by the U.S. government on various development programs within Government Systems, as detailed in the Government Systems Financial Results section below. Company-funded R&D expense decreased $5 million within Commercial Systems as we completed effort associated with various internally funded development programs and redirected other engineering resources towards pre-production engineering programs that are capitalized within inventory, including the Boeing 737 MAX, Bombardier CSeries and Global 7000/8000. The $4 million reduction to company funded R&D expense within Government Systems was primarily attributable to the completion of development effort for GPS and networked communication products.

Selling, General and Administrative Expenses

	Three Months Ended
	December 31
(dollars in millions)	2012			2011
Selling, general and administrative expenses	$	124		$	124
Percent of total sales	11.7		%	11.3		%

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 December 31, 2012 were comparable to the amount reported in the same period last year.

Net Income and Diluted Earnings Per Share

	Three Months Ended
	December 31
(dollars in millions, except per share amounts)	2012			2011
Net income	$	132		$	130
Percent of sales	12.4		%	11.9		%
Diluted earnings per share	$	0.94		$	0.86

Net income for the three months ended December 31, 2012 increased 2 percent, or $2 million to $132 million from $130 million of net income for the three months ended December 31, 2011. Diluted earnings per share from continuing operations increased 9 percent to $0.94 for the three months ended December 31, 2012 compared to $0.86 for the three months ended December 31, 2011. The rate of increase in diluted earnings per share was greater than the percentage rate increase in net income because of the favorable impact from our share repurchase program.

Net income was impacted by the lower operating earnings within Government Systems, which were more than offset by the combined impact of higher operating earnings within Commercial System and a benefit from lower income tax expense. The lower income tax expense was primarily related to the recognition of tax benefits from net operating loss carryovers in the United Kingdom that resulted in a benefit to net income and earnings per share during the three months ended December 31, 2012.

Government Systems Financial Results

Government Systems Sales

The following table presents Government Systems sales by product category:

	Three Months Ended
	December 31
(dollars in millions)	2012			2011
Avionics	$	315		$	324
Communication products	133			144
Surface solutions	50			60
Navigation products	48			55
Total	$	546		$	583
Percent (decrease)	(6		)%

Avionics sales decreased $9 million, or 3 percent, for the three months ended December 31, 2012 compared to the same period in the prior year, primarily due to the following:

• $17 million decrease from reduced development for our content on the E-6 aircraft and other programs that completed or are expected to transition to full scale production after 2013

• partially offset by an $10 million increase from continued development effort on the KC-46A and KC-10 tanker aircraft programs

Communication products sales decreased $11 million, or 8 percent, for the three months ended December 31, 2012 compared to the same period in the prior year, primarily due to a $16 million reduction in deliveries of legacy airborne communication systems and satellite communication terminals, partially offset by increased sales of ground based software defined radios.

Surface solutions sales decreased $10 million, or 17 percent, for the three months ended December 31, 2012 compared to the same period in the prior year, primarily due to the following:

• $14 million reduction attributable to the completion of development effort on various integration and electronic warfare programs

• partially offset by a $4 million increase in Firestorm targeting system revenues attributable to recently awarded positions on international programs

Navigation products sales decreased $7 million, or 13 percent, for the three months ended December 31, 2012 compared to the same period in the prior year, largely driven by a reduction in deliveries of our Defense Advanced GPS Receiver products as troop deployments wind down in Afghanistan and Iraq.

Government Systems Segment Operating Earnings

	Three Months Ended
	December 31
(dollars in millions)	2012			2011
Segment operating earnings	$	107		$	117
Percent of sales	19.6		%	20.1		%

20

Government Systems operating earnings were $107 million, or 19.6 percent of sales, for the three months ended December 31, 2012, compared to operating earnings of $117 million, or 20.1 percent of sales, for the same period one year ago. The $10 million decrease in Government Systems operating earnings was primarily due to the following:

• the $37 million reduction in sales discussed in the Government Systems sales section above resulted in a $19 million decrease to costs and a reduction to earnings of $18 million, or 49 percent of the sales volume reduction. This gross margin impact from the sales volume reduction reflects an unfavorable shift in product mix as prior year results included higher margin hardware sales for Communication and Navigation products

• partially offset by an $8 million benefit to operating earnings attributable to the combined impact of lower company-funded R&D expense and other savings realized from headcount reduction and restructuring actions initiated in the prior year

The decrease in Government Systems operating earnings as a percent of sales was primarily due to the lower sales volume, partially offset by the favorable impact of lower company-funded R&D 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
	December 31
(dollars in millions)	2012			2011
Air transport aviation electronics:
Original equipment	$	140		$	124
Aftermarket	112			120
Wide-body in-flight entertainment products and services	27			25
Total air transport aviation electronics	279			269
Business and regional aviation electronics:
Original equipment	142			141
Aftermarket	95			101
Total business and regional aviation electronics	237			242
Total	$	516		$	511
Percent increase	1		%

Total air transport aviation electronics sales increased $10 million, or 4 percent, for the three months ended December 31, 2012 compared to the same period in the prior year due to the following:

• original equipment manufacturer (OEM) revenues increased $16 million, or 13 percent. This increase was primarily due to increased deliveries from higher aircraft production rates for the Boeing 787 platform and increased deliveries on the Airbus A330 platform

• aftermarket sales declined $8 million, or 7 percent, driven by lower spare parts sales as a large number of deliveries occurred last year for aircraft entering into service

• wide-body in-flight entertainment products and services increased $2 million as a $7 million last-time buy order for spare parts from an airline customer offset other declines attributable to our previously announced decision to cease investing in this product area

Business and regional aviation electronics sales decreased $5 million, or 2 percent, for the three months ended December 31, 2012 compared to the same period in the prior year due to the following:

• OEM sales increased $1 million, or 1 percent, as higher product deliveries for Bombardier Global aircraft were mostly offset by reduced sales to customers at the light-end of the business jet market

21

• aftermarket sales decreased $6 million, or 6 percent, driven by a reduction in spare parts sales as prior year results included large deliveries for military special mission programs and Chinese regional jet aircraft

Commercial Systems Segment Operating Earnings

	Three Months Ended
	December 31
(dollars in millions)	2012			2011
Segment operating earnings	$	106		$	101
Percent of sales	20.5		%	19.8		%

Commercial Systems operating earnings increased $5 million, or 5 percent, to $106 million, or 20.5 percent of sales, for the three months ended December 31, 2012 compared to operating earnings of $101 million, or 19.8 percent of sales, for the three months ended December 31, 2011.

The $5 million increase in Commercial Systems operating earnings, and the increase in Commercial Systems operating earnings as a percent of sales, were primarily attributable to the benefit of lower company-funded R&D expenses, as discussed in the Cost of Sales section above.

General Corporate, Net

General corporate expenses that are not allocated to our business segments are included in general corporate, net. These costs are included within Cost of sales, SG&A expense and Other Income, net on the Condensed Consolidated Statement of Operations. General Corporate, net is summarized as follows:

	Three Months Ended
	December 31
(dollars in millions)	2012		2011
General corporate, net	$	13	$	12

General corporate net costs for the three months ended December 31, 2012 were comparable to the amount reported in the same period last year.

Retirement Plans

Net benefit expense for pension benefits and other retirement benefits are as follows:

	Three Months Ended
	December 31
(dollars in millions)	2012		2011
Pension benefits	$	2	$	(3	)
Other retirement benefits	4		5
Net benefit expense	$	6	$	2

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.

For the full year 2013, we expect defined benefit pension expense of $7 million, compared to $13 million of income for the full year 2012. In fiscal year 2013, the expected long-term rate of return on plan assets for both U.S. Pension Benefits and Other Retirement Benefits was reduced to 8.25 percent compared to 8.75 percent for fiscal year 2012.

22

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.

During the three months ended December 31, 2012, we made $55 million of contributions to our U.S. qualified pension plan. In January 2013, subsequent to our first quarter, we made an additional $55 million contribution to our U.S. qualified plan. We do not expect to make any additional contributions to our U.S. qualified pension plan during 2013. Contributions to our non-U.S. plans and U.S. non-qualified plan are anticipated to total $14 million in 2013. For the three months ended December 31, 2012 and 2011, we made contributions to our non-U.S. plans and U.S. non-qualified pension plan of $2 million and $3 million, respectively.

Other Retirement Benefits

We expect other retirement benefits expense of approximately $15 million for the full year fiscal 2013 compared to the full year 2012 expense of $18 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), which provides a tax benefit on certain incremental R&D expenditures and the Domestic Manufacturing Deduction, which provides a tax benefit on U.S. based manufacturing.

During the three months ended December 31, 2012 and 2011, the effective income tax rate was 29.8 percent and 33.0 percent, respectively. The effective income tax rate for the three months ended December 31, 2012 was lower than the same period of the prior year primarily due to the recognition of the tax benefit from net operating loss carryovers in the United Kingdom.

On January 2, 2013, subsequent to our first quarter, the American Taxpayer Relief Act of 2012 was enacted which retroactively reinstated and extended the Federal Research and Development Tax Credit (Federal R&D Tax Credit) from January 1, 2012 to December 31, 2013. As a result, we expect our income tax provision for the second quarter of fiscal year 2013 will include a discrete tax benefit that will reduce our annual effective income tax rate by approximately 2 percent for the previously expired period from January 1, 2012 to September 30, 2012.

For fiscal year 2013, our effective income tax rate is projected to be about 27 percent and has been updated to include the full year impact of the Federal R&D Tax Credit extension.

FINANCIAL CONDITION AND LIQUIDITY

Cash Flow Summary

Our ability to generate cash flow from operating activities coupled with our expected ability to access the credit markets enables us to execute our growth strategies and return value to our shareowners. The timing of our cash inflows is historically heavily weighted towards the second half of our fiscal year, particularly to our fourth quarter. We expect this trend to continue in the future.

Operating Activities

	Three Months Ended
	December 31
(in millions)	2012		2011
Cash provided by (used for) operating activities	$	63	$	(64	)

23

The $127 million increase in cash provided by operating activities during the three months ended December 31, 2012 compared to the same period last year was primarily due to the following:

• payments for employee incentive pay decreased $79 million during the first three months of fiscal year 2013, compared to the same period last year. Incentive pay is expensed in the year it is incurred and paid in the first fiscal quarter of the following year. During the first three months of fiscal year 2013, $54 million was paid for employee incentive pay costs incurred during 2012. During the first three months of fiscal year 2012, $133 million was paid for employee incentive pay costs incurred during 2011

• cash receipts from customers increased by $26 million to $1,169 million during the first three months of 2013, compared to $1,143 million during the same period last year. The increase was primarily attributable to higher progress payments and cash advances received from customers, partially offset by the lower sales volume discussed in the Results of Operations section above

• the remaining increase to operating cash flows of $22 million was primarily attributable to lower payments for production inventory and other operating costs that resulted from the lower sales volume

Investing Activities

	Three Months Ended
	December 31
(in millions)	2012			2011
Cash used for investing activities	$	(40	)	$	(47	)

The $7 million decrease in cash used for investing activities during the three months ended December 31, 2012 compared to the same period last year was primarily due to the timing of capital expenditures. For the full year 2013, we expect $140 million of capital expenditures, which is comparable to the $138 million of capital expenditures in full year 2012.

Financing Activities

	Three Months Ended
	December 31
(in millions)	2012			2011
Cash used for financing activities	$	(25	)	$	(128	)

The $103 million decrease in cash used for financing activities during the three months ended December 31, 2012 compared to the same period last year was primarily due to the following:

• cash repurchases of common stock decreased $57 million to $336 million for the three months ended December 31, 2012 compared to $393 million for the three months ended December 31, 2011

• higher net borrowings of $50 million. During the three months ended December 31, 2012, net proceeds from short-term commercial paper borrowings were $345 million, compared to net proceeds from short-term commercial paper borrowings and long-term debt of $295 million during the same period last year

Financial Condition and Liquidity

We have historically maintained a capital structure characterized by conservative levels of debt outstanding that enables us sufficient access to credit markets. When combined with our ability to generate 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.

24

A comparison of key elements of our financial condition as of December 31, 2012 and September 30, 2012 are as follows:

(dollars in millions)	December 31, 2012			September 30, 2012
Cash and cash equivalents	$	337		$	335
Short-term debt	(549		)	—
Long-term debt, net	(573		)	(779		)
Net debt (1)	$	(785	)	$	(444	)
Total equity	$	1,057		$	1,264
Debt to total capitalization (2)	51		%	38		%
Net debt to total capitalization (3)	43		%	26		%

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

(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

We primarily fund our contractual obligations, capital expenditures, small to medium sized acquisitions, dividends and share repurchases from cash generated from operating activities. As of December 31, 2012, approximately 91 percent of our cash and cash equivalents resides at non-U.S. locations and may not be readily accessible for use in the U.S. due to adverse income tax implications and other statutory limitations. 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 December 31, 2012, short-term commercial paper borrowings outstanding were $345 million with a weighted-average interest rate and maturity period of 0.18 percent and 9 days, respectively. These commercial paper borrowings were incurred to fund a portion of the Company's share repurchase program. The maximum amount of short-term borrowings outstanding during the three months ended December 31, 2012 was $362 million. At September 30, 2012, there were no outstanding short-term commercial paper borrowings.

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 2016, 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 December 31, 2012 based on this financial covenant was 30 percent. We had no borrowings at December 31, 2012 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. 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. On January 8, 2013, Moody's reduced our long-term senior unsecured debt rating to A2 from A1. Moody's reaffirmed our short-term debt rating of P-1. On January 16, 2013, Standard and Poor's reaffirmed our long-term senior unsecured debt rating of A, but revised the outlook from Stable to Negative. We do not believe these rating actions will materially impact our access to or cost of long-term financing. If our credit ratings were to be further 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 current credit ratings:

Credit Rating Agency	Short-Term Rating	Long-Term Rating	Outlook
Fitch Ratings	F1	A	Stable
Moody’s Investors Service	P-1	A2	Stable
Standard & Poor’s	A-1	A	Negative

We were in compliance with all debt covenants at December 31, 2012 and September 30, 2012.

Actual results in these areas could differ from management's estimates.

CAUTIONARY STATEMENT

This quarterly report contains statements, including certain projections and business trends, that are forward-looking statements as defined in the Private Securities Litigation Reform Act of 1995. Actual results may differ materially from those projected as a result of certain risks and uncertainties, including but not limited to the financial condition of our customers, including bankruptcies; the health of the global economy, including potential deterioration in economic and financial market conditions; the rate of recovery of the commercial OEM production rates and the aftermarket; the impacts of natural disasters, including operational disruption, potential supply shortages and other economic impacts; cybersecurity threats, including the potential misappropriation of assets or other sensitive information, corruption of data or operational disruption;delays related to the award of domestic and international contracts; unanticipated impacts of sequestration and other provisions of the Budget Control Act of 2011 that are set to be implemented in March 2013; the discontinuance of support for military transformation and modernization programs; potential adverse impact of oil prices on the commercial aerospace industry; the impact of terrorist events on the commercial aerospace industry; declining defense budgets resulting from budget deficits in the U.S. and abroad; changes in domestic and foreign government spending, budgetary, procurement and trade policies adverse to our businesses; market acceptance of our new and existing technologies, products and services; reliability of and customer satisfaction with our products and services; favorable outcomes on or potential cancellation or restructuring of contracts, orders or program priorities by our customers; timing of international contract awards; recruitment and retention of qualified personnel; regulatory restrictions on air travel due to environmental concerns; effective negotiation of collective bargaining agreements by us and our customers, including our collective bargaining agreements set to expire in May 2013; performance of our customers and subcontractors; risks inherent in development and fixed-price contracts, particularly the risk of cost overruns; risk of significant reduction to air travel or aircraft capacity beyond our forecasts; our ability to execute to our internal performance plans such as our productivity and quality improvements and cost reduction initiatives; achievement of our acquisition and related integration plans; continuing to maintain our planned effective tax rates; our ability to develop contract compliant systems and products on schedule and within anticipated cost estimates; risk of fines and penalties related to noncompliance with laws and regulations including export control and environmental regulations; risk of asset impairments; our ability to win new business and convert those orders to sales within the fiscal year in accordance with our annual operating plan; and the uncertainties of the outcome of lawsuits, claims and legal proceedings, as well as other risks and uncertainties, including but not limited to those detailed herein and from time to time in our Securities and Exchange Commission filings. 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.

26

At December 31, 2012, we had $200 million of 4.75 percent fixed rate short-term debt obligations outstanding with a carrying value of $200 million and a fair value of $208 million. In November 2003 we converted $100 million of this fixed rate debt to floating rate debt bearing interest at six-month LIBOR less 0.075 percent by executing “receive fixed, pay variable” interest rate swap contracts. At December 31, 2012, 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 $364 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. Finally, at December 31, 2012, we had $250 million of 3.10 percent fixed rate unsecured long-term debt with a carrying value of $249 million and a fair value of $265 million.

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 $5 million and $5 million, respectively, and would not have impacted the value of our short-term fixed rate debt. The fair value of the $250 million notional value of interest rate swap contracts was a $29 million net asset at December 31, 2012. 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 $1 million, respectively. 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 8, 13 and 14 in the Notes to Condensed Consolidated Financial Statements.

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 $359 million and $393 million at December 31, 2012 and September 30, 2012, 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, British pound sterling and Japanese yen. The duration of foreign currency contracts is generally five years or less. The net fair value of these foreign currency contracts netted to zero at December 31, 2012 and was a net asset of $2 million at September 30, 2012. 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 December 31, 2012 by $9 million. For more information related to outstanding currency forward exchange contracts, see Notes 13 and 14 in the Notes to Condensed Consolidated Financial Statements.

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 December 31, 2012, 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 December 31, 2012 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.

Item 5.      Other Information

As explained in Note 2 of the Notes to Condensed Consolidated Financial Statements, in June 2011, the Financial Accounting Standards Board issued guidance on the presentation of comprehensive income in the financial statements. Entities are required to present total comprehensive income either in a single, continuous statement of comprehensive income or on separate but consecutive statements, the statement of operations and the statement of other comprehensive income (OCI). The amendment became effective for the Company for the quarter ended December 31, 2012, and the Company has elected to report OCI as a separate but consecutive statement.

The table below reflects the retrospective application of this guidance for each of the three years ended September 30, 2012, 2011 and 2010. The retrospective application did not have any impact on the Company's financial position, results of operations or cash flows as a result of this amendment.

Appendix A

Compensation Recovery Policy

Rockwell Collins, Inc.

Introduction. Rockwell Collins, Inc. (the “Company) has adopted this Compensation Recovery Policy (the “Policy”) to allow it to forfeit and recover certain compensation awarded or paid to a Covered Executive (as defined below), if the Company's Board of Directors determines in its sole discretion that the Covered Executive engaged in fraud or illegal activity and as a result there was a substantial negative impact to the Company or its financial condition, including, but not limited to, a need for the Company to file a financial restatement.

Covered Executives. This Policy applies to (a) executive officers designated by the Company's Board of Directors as officers for purposes of Section 16 of the Securities Exchange Act of 1934, as amended, (b) all other employees of the Company (or a subsidiary) in positions with the title of Vice President & General Manager or Vice President & Controller and (c) any employees of the Company (or a subsidiary) who are designated by the Company's Chief Executive Officer (collectively the groups referred to in (a), (b) and (c) shall be referred to as “Covered Executives”). This Policy applies to Covered Executives, whether or not they are employed by the Company or an affiliate thereof at the time of the discovery of the fraud or illegal activity.

Recovery of Incentive Compensation. If the Board determines, in its sole discretion, that a Covered Executive engaged in fraud or illegal activity and as a result there was a substantial negative impact to the Company or its financial condition, then the Covered Executive shall, as directed by the Board and to the extent permitted by law: (a) forfeit any outstanding equity-based awards, vested or unvested, granted by the Company to the Covered Executive during the Company's fiscal year in which the fraud or illegal activity was discovered, and (b) repay the Company, in cash and upon demand, an amount up to (i) the gross amount paid to the Covered Executive under the Company's Incentive Compensation Plan and/or the Company's 2006 Annual Incentive Compensation Plan for Senior Executives for each of the three most recently completed fiscal years of the Company (assuming for this purpose that any deferral of this payment made by the Covered Executive to the Company's 2005 Deferred Compensation Plan was paid to the Covered Executive), (ii) the aggregate Fair Market Value (as defined in the Company's 2006 Long-Term Incentives Plan, as amended) paid to the Covered Executive upon the vesting of performance share awards for each of the three most recently completed performance periods for such awards and (iii) the gains (i.e., taxable income) received in the preceding three years upon the exercise of stock options granted to the Covered Executive by the Company (assuming, for this purpose, that any incentive stock option was a nonqualified stock option). Notwithstanding the foregoing, no forfeiture or repayment shall be required by virtue of the immediately preceding sentence on or after the date of a Change of Control (as defined in the Company's 2006 Long-Term Incentives Plan, as amended) unless and until there shall have been delivered to the Covered Executive a copy of the resolution duly adopted by the affirmative vote of not less than three-quarters of the entire membership of the Company's Board of Directors at the meeting of the Board called and held for such purpose (after reasonable notice is provided to the Covered Executive and the Covered Executive is given an opportunity,

together with counsel, to be heard before the Board), finding that, in the good faith opinion of the Board, the Covered Executive engaged in fraud or illegal activity and as a result there was a substantial negative impact to the Company or its financial condition, and specifying the particulars thereof in detail. A Covered Executive shall not be deemed to have engaged in fraud or illegal activity for purposes of this Policy if he or she acted with a good faith and reasonable belief that his or her activity was not fraudulent or illegal and was in or not opposed to the Company's best interests.

Incorporation by Reference. Each award agreement or other document setting forth the terms and conditions of any incentive compensation granted to a Covered Executive may include a provision by referenceincorporating the requirements of this Policy with respect to such award, but this Policy shall apply regardless of whether such provision is included. The remedies specified in this Policy shall not be exclusive and shall be in addition to every other right or remedy at law or in equity that may be available to the Company.

Enforcement and Interpretation. The Board of Directors shall have full and final authority to make all determinations under this Policy, including without limitation, whether a Covered Executive engaged in fraud or illegal activity, the impact of his or her actions on the Company and the amount and type of compensation to be repaid or forfeited by the Covered Executive. All determinations and decisions made by the Board of Directors pursuant to the provisions of this Policy shall be final, conclusive and binding on all persons, including the Company, its affiliates, its shareowners and employees.

Restructuring Costs and Asset Impairment Charges [Abstract]

Restructuring and Asset Impairment Charges

Restructuring and Asset Impairment Charges, Net

During the year ended September 30, 2012, the Company recorded corporate restructuring and asset impairment charges, net totaling $58 million. Included in this charge was $35 million related to employee severance costs, primarily resulting from decisions to realign the Company's European organizational structure to better position the business for long-term growth and to adjust the size of our workforce in preparation for the sequestration impacts on the U.S. defense budgets. During the three months ended December 31, 2012, the Company made cash severance payments of $3 million. As of December 31, 2012, $28 million of employee severance costs related to this action remains to be paid in future periods.

During the year ended September 30, 2011, the Company recorded restructuring and asset impairment charges totaling $27 million. This amount was primarily comprised of non-cash asset impairment charges of $11 million, employee severance of $7 million, and $9 million of other costs, primarily attributable to a lease termination. The charges related to decisions to implement certain business realignment and facility rationalization actions in response to global economic factors that have negatively impacted the Company's Government Systems segment. All actions have been completed except for a remaining lease termination payment of $3 million which will be paid in future periods.

Customer Incentives Policy

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 are amortized using a units-of-delivery method over the period the Company has received a contractually enforceable right related to the incentives, up to 15 years. Amortization is based on the Company’s expectation of delivery rates on a program-by-program basis. Amortization begins when the Company starts recognizing revenue as the Company delivers equipment for the program. 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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Business Description and Basis of Presentation

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, December 31 and September 30 are utilized consistently throughout these financial statements and notes to represent the period end date.

The Company has one consolidated subsidiary with income attributable to a noncontrolling interest. The net income and comprehensive income attributable to the noncontrolling interest is insignificant.

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, 2012.

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 months ended December 31, 2012 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.

During the second quarter of fiscal 2012, the Company determined that certain product sales had erroneously been presented as service sales in previously issued financial statements. With the correction, service sales are less than ten percent of total sales for all periods presented. Accordingly, service and product sales are no longer separately presented. This change did not impact previously reported total revenues, total cost of sales, or net income, nor did it have any effect on the Company's financial position or cash flows for any prior periods.

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.

Changes in the carrying amount of accrued product warranty costs are summarized as follows:

Changes in estimates for prior years	(2		)	(3		)
Foreign currency translation adjustments	—			(1		)
Balance at December 31	$	121		$	142

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 December 31, 2012, the outstanding loan balance was approximately $5 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 December 31, 2012, 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 December 31, 2012 were $73 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.

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.

Legal Matters Abstract

Legal Matters

Legal Matters and Other Uncertainties

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 effect on the Company's business or financial position, but could possibly be significant to the results of operations or cash flows of any one quarter.

The Company depends to a large degree on U.S. Government spending, as a significant portion of the Company's sales are derived from U.S. Government contracts, both directly and indirectly through subcontracts. In August 2011, Congress enacted the Budget Control Act of 2011 (BCA) which imposes spending caps and certain reductions in security spending over a ten-year period through 2021. Absent additional Congressional action, further budget cuts, referred to as sequestration, will be implemented in March 2013. Future reductions in U.S. Government security spending could have a significant adverse impact on the financial results of the Company's Government Systems operating segment. While management believes the Company's product offerings are well positioned to meet the needs of its customer base, any material deterioration in the economic and environmental factors that impact the aerospace and defense industries could have a material adverse effect on the Company's results of operations, financial position or cash flows.

The Company defers certain pre-production engineering costs during the development phase of a 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 using a units-of-delivery method, up to 15 years. This amortization expense is included as a component of cost of sales. Amortization is based on the Company’s expectation of delivery rates on a program-by-program basis and begins when the Company starts recognizing revenue as the Company delivers equipment for the program. 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.

Anticipated annual amortization expense for pre-production engineering costs is as follows:

(in millions)	2013		2014		2015		2016		2017		Thereafter
Anticipated amortization expense	$	29	$	44	$	64	$	75	$	79	$	319

Amortization expense for pre-production engineering costs for the three months ended December 31, 2012 was $5 million compared with $3 million for the three months ended December 31, 2011. During the fourth quarter of 2012, the Company reclassified this amortization on the Condensed Consolidated Statement of Cash Flows from changes in Inventories to Amortization of intangible assets and pre-production engineering costs for all periods presented. As of December 31, 2012, the weighted average amortization period remaining for pre-production engineering costs included in Inventories, net was approximately 10 years.

Environmental Remediation Obligations [Abstract]

Environmental Matters

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 December 31, 2012, 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 $12 million. Environmental reserves for this site were $6 million and $6 million as of December 31, 2012 and September 30, 2012, respectively, 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 effect on the Company’s business or financial position, but could possibly be significant to the results of operations or cash flows of any one quarter.

Income Taxes

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 December 31, 2012 and 2011, the effective income tax rate was 29.8 percent and 33.0 percent, respectively.

The effective income tax rate for the three months ended December 31, 2012 was lower than the same period of the prior year primarily due to the recognition of the tax benefit from net operating loss carryovers in the United Kingdom.

On January 2, 2013, subsequent to the first quarter, the American Taxpayer Relief Act of 2012 was enacted which retroactively reinstated and extended the Federal Research and Development Tax Credit (Federal R&D Tax Credit) from January 1, 2012 to December 31, 2013. As a result, the Company expects its income tax provision for the second quarter of fiscal year 2013 will include a discrete tax benefit that will reduce the annual effective income tax rate by approximately 2 percent for the previously expired period from January 1, 2012 to September 30, 2012.

The Company's U.S. Federal income tax returns for the tax years ended September 30, 2009 and prior have been audited by the Internal Revenue Service (IRS) and are closed to further adjustments. The IRS is currently auditing the Company's returns for the years ended September 30, 2010 and 2011. The Company is also currently under audit in various U.S. state and non-U.S. jurisdictions, which 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 $12 million and $24 million during the three months ended December 31, 2012 and 2011, respectively.

The Company had gross unrecognized tax benefits recorded within Other Liabilities in the Condensed Consolidated Statement of Financial Position of $45 million and $42 million as of December 31, 2012 and September 30, 2012, respectively. The total amounts of unrecognized tax benefits that, if recognized, would affect the effective income tax rate were $25 million and $24 million as of December 31, 2012 and September 30, 2012, respectively. 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 of approximately $0 million to $26 million based on the outcome of tax examinations or as a result of the expiration of various statutes of limitations.

The Company includes interest and penalties related to unrecognized tax benefits in income tax expense. The total amount of interest and penalties recognized within Other Liabilities in the Condensed Consolidated Statement of Financial Position was approximately $2 million and $2 million as of December 31, 2012 and September 30, 2012. 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 $0 million and $0 million for the three months ended December 31, 2012 and 2011.

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 0.075 percent. See Notes 13 and 14 for additional information relating to the interest rate swap contracts. The 2013 Notes mature within one year and as of December 31, 2012, are included in the Condensed Consolidated Statement of Financial Position net of any unamortized discount within the caption Short-term Debt.

The 2013 Notes 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. The Company was in compliance with all debt covenants at December 31, 2012 and September 30, 2012.

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 December 31, 2012, short-term commercial paper borrowings outstanding were $345 million with a weighted-average interest rate and maturity period of 0.18 percent and 9 days, respectively. At September 30, 2012, there were no outstanding short-term commercial paper borrowings.

On May 26, 2011, the Company entered into an $850 million five-year unsecured revolving credit facility with various banks. 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 30 percent as of December 31, 2012. The credit facility includes 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. The credit facility also contains 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 December 31, 2012 and September 30, 2012, there were no outstanding borrowings under the revolving credit facility.

In addition, short-term credit facilities available to non-U.S. subsidiaries amounted to $57 million as of December 31, 2012, of which $17 million supports commitments in the form of commercial letters of credit. As of December 31, 2012 and September 30, 2012, there were no short-term borrowings outstanding under the Company’s non-U.S. subsidiaries’ credit facilities.

At December 31, 2012 and September 30, 2012, there were no significant commitment fees or compensating balance requirements under any of the Company’s credit facilities.

Long-term Debt

On November 16, 2011, the Company issued $250 million of 3.10 percent fixed rate unsecured debt due November 15, 2021 (the 2021 Notes). The net proceeds to the Company from the sale of the 2021 Notes, after deducting a $1 million discount and $2 million of debt issuance costs, were $247 million.

On May 6, 2009, the Company issued $300 million of 5.25 percent fixed rate unsecured debt due July 15, 2019 (the 2019 Notes). 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 13 and 14 for additional information relating to the interest rate swap contracts.

The 2021 and 2019 Notes are included in the Condensed Consolidated Statement of Financial Position net of any 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 debt issuance costs and any discounts are amortized over the life of the debt and recorded in Interest expense.

The 2021 and 2019 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. The Company was in compliance with all debt covenants at December 31, 2012 and September 30, 2012.

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 are amortized using a units-of-delivery method over the period the Company has received a contractually enforceable right related to the incentives, up to 15 years. Amortization is based on the Company’s expectation of delivery rates on a program-by-program basis. Amortization begins when the Company starts recognizing revenue as the Company delivers equipment for the program. 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. As of December 31, 2012, the weighted average amortization period remaining for up-front sales incentives was approximately 9 years.

Anticipated annual amortization expense for intangible assets is as follows:

(in millions)	2013		2014		2015		2016		2017		Thereafter

Amortization expense for intangible assets for the three months ended December 31, 2012 was $8 million compared to $10 million for the three months ended December 31, 2011.

The Company reviews Intangible Assets for impairment at least annually, or whenever potential indicators of impairment exist.

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 $33 million for the three months ended December 31, 2012 and $28 million for the three months ended December 31, 2011. The deferred portion of profit generated from sales to equity affiliates was $1 million and $3 million at December 31, 2012 and September 30, 2012, respectively.

Exchange and Rental Assets

Exchange and rental assets consist primarily of Company products that are either loaned or rented to customers on a short-term basis in connection with warranty and other service related activities. These assets are recorded at acquisition or production cost and depreciated using the straight-line method over their estimated lives up to 15 years. Depreciation expense for exchange and rental assets was $2 million and $2 million for the three months ended December 31, 2012 and December 31, 2011, respectively.

Derivative Financial Instruments

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

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 0.075 percent.

The Company has designated the 2019 Swap and 2013 Swap (the Swaps) as fair value hedges. The 2013 swap matures within one year and therefore is recorded within Other current assets at a fair value of $4 million offset by a fair value adjustment to Short-term debt (Note 8) of $4 million at December 31, 2012. The 2019 Swap is recorded within Other Assets at a fair value of $25 million, offset by a fair value adjustment to Long-term Debt (Note 8) of $25 million at December 31, 2012. At September 30, 2012, both Swaps were classified as long-term and were recorded within Other Assets at a fair value of $31 million, offset by a fair value adjustment to Long-term Debt (Note 8) of $31 million. 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 December 31, 2012 and September 30, 2012, the Company had outstanding foreign currency forward exchange contracts with notional amounts of $359 million and $393 million, respectively. These notional values consist primarily of contracts for the European euro, British pound sterling and Japanese yen, and are stated in U.S. dollar equivalents at spot exchange rates at the respective dates.

Fair Value of Derivative Instruments

Fair values of derivative instruments in the Condensed Consolidated Statement of Financial Position as of December 31, 2012 and September 30, 2012 are as follows:

		Asset Derivatives
(in millions)	Classification	December 31, 2012		September 30, 2012
Foreign currency forward exchange contracts	Other current assets	$	5	$	7
Interest rate swaps	Other assets	25		31
Interest rate swaps	Other current assets	4		—
Total		$	34	$	38

		Liability Derivatives
(in millions)	Classification	December 31, 2012		September 30, 2012
Foreign currency forward exchange contracts	Other current liabilities	$	5	$	5

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 December 31, 2012 and September 30, 2012, $0 million and $0 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 three months ended December 31, 2012 and 2011 is as follows:

		Amount of Gain (Loss)
		Three Months Ended
		December 31
(in millions)	Location of Gain (Loss)	2012			2011

Foreign currency forward exchange contracts	Cost of sales	$	—		$	(1	)

Amount of gain (loss) recognized in AOCL (effective portion, before deferred tax impact)	AOCL	$	(2	)	$	(1	)
Amount of gain (loss) reclassified from AOCL into income	Cost of sales	—			1

There was no significant impact to the Company’s earnings related to the ineffective portion of any hedging instruments during the three months ended December 31, 2012. 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 months ended December 31, 2012.

The Company did not have any hedges with credit-risk-related contingent features or that required the posting of collateral as of December 31, 2012. The cash flows from derivative contracts are recorded in operating activities in the Condensed Consolidated Statement of Cash Flows.

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 $2 million of net gains into earnings over the next 12 months. The maximum duration of a foreign currency cash flow hedge contract at December 31, 2012 was 91 months.

Pre-Production Engineering Costs Policy

The Company defers certain pre-production engineering costs during the development phase of a 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 using a units-of-delivery method, up to 15 years. This amortization expense is included as a component of cost of sales. Amortization is based on the Company’s expectation of delivery rates on a program-by-program basis and begins when the Company starts recognizing revenue as the Company delivers equipment for the program. 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.

Fair Value Measurements

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 December 31, 2012 and September 30, 2012 are as follows:

		December 31, 2012			September 30, 2012
(in millions)	Fair Value Hierarchy	Fair Value Asset (Liability)			Fair Value Asset (Liability)
Deferred compensation plan investments	Level 1	$	45		$	42
Interest rate swap assets	Level 2	29			31
Foreign currency forward exchange contract assets	Level 2	5			7
Foreign currency forward exchange contract liabilities	Level 2	(5		)	(5		)

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 three months ended December 31, 2012 or 2011.

The carrying amounts and fair values of the Company’s financial instruments are as follows:

	Asset (Liability)
	December 31, 2012						September 30, 2012
(in millions)	Carrying Amount			Fair Value			Carrying Amount			Fair Value
Cash and cash equivalents	$	337		$	337		$	335		$	335
Short-term debt	(545		)	(553		)	—			—
Long-term debt	(548		)	(629		)	(748		)	(837		)

The fair value of cash and cash equivalents and the commercial paper portion of the short-term debt approximate their carrying value due to the short-term nature of the instruments and these items are within Level 1 of the fair value hierarchy. Fair value information for the 2013 Notes classified as short-term debt and all long-term debt is within Level 2 of the fair value hierarchy and 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 short-term and 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.
