NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Business Description and Basis of Presentation

Rockwell Collins, Inc. (the Company or Rockwell Collins) designs, produces and supports communications and aviation systems for commercial and military customers and provides information management services through voice and data communication networks and solutions 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 dates.

The Company has one consolidated subsidiary with income attributable to 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, 2014.

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, 2014 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 first quarter of 2014, the Company acquired ARINC Incorporated (ARINC). As a result of the acquisition, the Company’s service sales are greater than ten percent of total sales. Accordingly, service and product sales and service and product cost of sales are presented separately and prior period results were reclassified to conform to the current year presentation. 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.

As discussed in Note 4, Discontinued Operations and Divestitures, on July 25, 2014 the Company divested its satellite communication systems business, formerly known as Datapath, Inc. (Datapath), with operations in Duluth, Georgia and Stockholm, Sweden. As a result, this business has been accounted for as discontinued operations for all periods presented. The Company also intends to divest ARINC's Aerospace Systems Engineering and Support (ASES) business, which provides military aircraft integration and modifications, maintenance, and logistics and support, in order to align with the Company's long-term primary business strategies. During the fourth quarter of 2014, the Company entered into an agreement to divest this business. Subsequently, during the quarter ended December 31, 2014, the parties mutually agreed to terminate the agreement and ASES remains classified as held-for-sale. The operating results of ASES are included in discontinued operations in the Company's Condensed Consolidated Statement of Operations for all periods presented.

2. Recently Issued Accounting Standards

In April 2014 the Financial Accounting Standards Board (FASB) issued guidance that modifies the criteria used to qualify divestitures for classification as discontinued operations and expands disclosures related to disposals of significant components. The amendment will become effective for the company in fiscal 2016 with early adoption permitted; the Company does not currently expect to early adopt the amended guidance. The amended guidance is expected to decrease the likelihood that future disposals will qualify for discontinued operations treatment, meaning that the results of operations of some future disposals may be reported in continuing operations.

ROCKWELL COLLINS, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(Unaudited)

In May 2014 the FASB issued a comprehensive new revenue recognition standard that effectively replaces all current guidance on the topic and expands disclosures regarding revenue. The guidance permits the use of either a retrospective or cumulative effect transition method. The new standard is effective for the Company in fiscal 2018 and early adoption is not permitted. The Company is currently evaluating the transition methods allowed under the new standard and the effect the standard will have on our consolidated financial statements and related disclosures. Given the new standard's impact on business processes, systems and internal controls, analysis of the new guidance will likely extend over several future periods.

3.Acquisitions

On December 23, 2013, the Company acquired 100 percent of the outstanding common stock and voting interests of Radio Holdings, Inc. (Radio Holdings), the holding company of ARINC, a leading global provider of air-to-ground data and voice communication services. ARINC develops and operates communications and information processing systems and provides systems engineering and integration solutions to five key industries: commercial aviation, business aviation, airports, rail and nuclear security. Combining ARINC's communication networks and services with the Company's onboard aircraft information systems strengthens the Company's ability to deliver enhanced connectivity to aircraft operators worldwide.

The ARINC purchase price was $1,405 million, net of cash acquired and net of $10 million in cash received by the Company in June 2014 from the settlement of various post-closing matters, including adjustments for changes in working capital. As discussed in Note 10, the Company used proceeds from the issuance of long-term debt and commercial paper to finance the cash purchase price. The following table summarizes the fair value of assets acquired and liabilities assumed at the acquisition date.

(in millions)	December 23, 2013
Restricted Cash(1)	$	61
Receivables and Other current assets	216
Building held for sale(2)	81
Business held for sale(3)	15
Property	49
Intangible Assets	431
Other Assets	11
Total Identifiable Assets Acquired	864
Payable to ARINC option holders(1)	(61		)
Current Liabilities	(171		)
Liability related to building held for sale(2)	(81		)
Liabilities associated with business held for sale(3)	(12		)
Long-term deferred income taxes	(182		)
Retirement Benefits and Other Long-term Liabilities	(39		)
Total Liabilities Assumed	(546		)
Net Identifiable Assets Acquired, excluding Goodwill	318
Goodwill	1,087
Net Assets Acquired	$	1,405

⁽¹⁾ Option-holders of ARINC were due approximately $61 million at the transaction closing date. This payment did not clear until December 24, 2013. Therefore the opening balance sheet, which was prepared as of December 23, 2013, includes restricted cash of $61 million and a current liability payable to the ARINC option holders for an equal amount.

⁽²⁾ On March 28, 2014, the Company sold the building which was classified as held for sale at the acquisition date. For more information related to the Building held for sale, see discussion below.

⁽³⁾ Assets and liabilities associated with the Business held for sale relate to ASES, which the Company intends to divest, as detailed in Note 4.

ROCKWELL COLLINS, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(Unaudited)

The final determination of the fair value of certain assets and liabilities was completed during the first quarter of 2015, within the one year measurement period as allowed by FASB Accounting Standards Codification Topic 805, Business Combinations (ASC 805). As of December 31, 2014, the valuation studies necessary to determine the fair market value of the assets acquired and liabilities assumed were complete.

The purchase price allocation resulted in the recognition of $1,087 million of goodwill, none of which is expected to be deductible for tax purposes. All of the goodwill is included in the Company’s Information Management Services segment. The goodwill is primarily a result of revenue synergy opportunities generated by the combination of the Company’s aviation electronics and flight services business with ARINC’s network communication solutions and cost synergies resulting from the consolidation of certain corporate and administrative functions. Goodwill also results from the workforce acquired with the business. See Note 22 for additional information relating to the Information Management Services segment.

ARINC’s results of operations have been included in the Company's operating results for the period subsequent to the completion of the acquisition on December 23, 2013. For the three months ending December 31, 2014 and 2013, ARINC contributed sales of $137 million and $6 million, respectively and net income of $12 million and $1 million, respectively.

Building Held For Sale and Liability Related to Building Held for Sale

In connection with the acquisition of ARINC, the Company classified $81 million of acquired real estate assets as Building held for sale at the acquisition date, as well as an $81 million liability related to the Building held for sale at the acquisition date. The assets and related liability were recorded at their estimated fair value.

In November 2004, ARINC obtained approval from the Department of Labor to contribute these real estate assets to its defined benefit pension plan. In connection with this transaction, ARINC entered into a simultaneous agreement to leaseback the contributed facilities for a period of twenty years, through November 1, 2024. As a result of the related party elements of the transaction, no sale or gain was recognized when ARINC contributed the real estate to its pension plan. Instead, ARINC recognized a deferred gain liability equal to the fair value of the contributed real estate. The increase in deferred gain liability was offset by an equal reduction to pension plan liabilities to recognize the fair value of the contributed real estate in the funded status of the pension plan.

The Building held for sale was comprised of the land and buildings of the ARINC corporate headquarters located in Annapolis, Maryland. The related liability represented future rental payment obligations under the leaseback agreement. As of the acquisition date, the real estate assets were being marketed for sale. In March 2014, the assets were sold to an unrelated third party. The net proceeds from the sale of $81 million were remitted directly to the ARINC pension plan, and have been included as a benefit to the funded status of that plan. The sale had no impact on the Company's Condensed Consolidated Statement of Operations or Condensed Consolidated Statement of Cash Flows.

Concurrent with the sale of the real estate assets, the Company entered into revised lease agreements with the new owner of the Annapolis, Maryland facilities, extending the lease term for a portion of the facility through March 31, 2029. A portion of the leased assets have been classified as a capital lease resulting in the establishment of capital lease assets and offsetting capital lease obligation on the Company's Condensed Consolidated Statement of Financial Position.

Supplemental Pro-Forma Data

The following unaudited supplemental pro-forma data presents consolidated pro-forma information as if the acquisition and related financing had been completed as of the beginning of the prior year, or on October 1, 2013.

The unaudited supplemental pro-forma financial information does not reflect the potential realization of revenue synergies or cost savings, nor does it reflect other costs relating to the integration of the two companies. This pro-forma data should not be considered indicative of the results that would have actually occurred if the acquisition and related financing been consummated on October 1, 2013, nor are they indicative of future results.

ROCKWELL COLLINS, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(Unaudited)

The unaudited supplemental pro-forma financial information was calculated by combining the Company's results with the stand-alone results of ARINC for the pre-acquisition period, which were adjusted to account for certain transactions and other costs that would have been incurred during this pre-acquisition period.

	Three Months Ended December 31
(in millions, except per share amounts)	2014		2013
Pro-forma sales	$	1,226	$	1,160
Pro-forma net income attributable to common shareowners from continuing operations	$	169	$	139
Pro-forma basic earnings per share from continuing operations	$	1.28	$	1.03
Pro-forma diluted earnings per share from continuing operations	$	1.26	$	1.02

The unaudited supplemental pro-forma data above exclude the results of ASES, which the Company intends to divest, as detailed in Note 4. The following significant adjustments were made to account for certain transactions and costs that would have occurred if the acquisition had been completed on October 1, 2013. These adjustments are net of any applicable tax impact and were included to arrive at the pro-forma results above. As the acquisition of ARINC was completed on December 23, 2013, the pro forma adjustments for the three months ended December 31, 2013 in the table below include only the required adjustments through December 23, 2013.

	Three Months Ended December 31
(in millions)	2014		2013
Increases / (decreases) to pro-forma net income:
Net reduction to depreciation resulting from fixed asset purchase accounting adjustments(1)	$	—	$	2
Advisory, legal and accounting service fees(2)	—		20
Amortization of acquired ARINC intangible assets, net(3)	—		(4		)

⁽¹⁾ This adjustment captures the net impact to depreciation expense resulting from various purchase accounting adjustments to fixed assets

⁽²⁾ This adjustment reflects the elimination of transaction-related fees incurred by ARINC and Rockwell Collins in connection with the acquisition and assumes all of the fees were incurred during the first quarter of 2013

⁽³⁾ This adjustment eliminates amortization of the historical ARINC intangible assets and replaces it with the new amortization for the acquired intangible assets

4. Discontinued Operations and Divestitures

On July 25, 2014, the Company sold its satellite communication systems business formerly known as Datapath, Inc. (Datapath). The sales price, which is subject to post-closing adjustments for changes in working capital and other items, was $10 million. The Company recognized a pre-tax loss of $12 million ($2 million after-tax) related to the divestiture of the Datapath business. The high effective tax rate is primarily attributable to differences in the treatment of goodwill for income tax and financial reporting purposes. The operating results of Datapath, including the loss realized on the disposition, have been included in discontinued operations in the Company's Condensed Consolidated Statement of Operations for all periods presented. The Datapath business was formerly included in the Government Systems segment. The divestiture of this business is part of our strategy to reshape the Government Systems segment to align with the changing dynamics of the defense environment and focus on opportunities in addressed markets for the Company's core products and solutions.

The Company also intends to divest ARINC's ASES business, which provides military aircraft integration and modifications, maintenance, and logistics and support, in order to align with the Company's long-term primary business strategies. During the fourth quarter of 2014, the Company entered into an agreement to divest this business. Subsequently, during the quarter ended December 31, 2014, the parties mutually agreed to terminate the agreement and ASES remains classified as held-for-sale. The operating results of ASES are included in discontinued operations in the Company's Condensed Consolidated Statement of Operations for all periods presented.

ROCKWELL COLLINS, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(Unaudited)

As of December 31, 2014, the Company has classified $17 million of assets related to ASES as a business held-for-sale within current assets and $12 million of liabilities related to ASES as a business held-for-sale within current liabilities on the Condensed Consolidated Statement of Financial Position. The held-for-sale assets are primarily comprised of Receivables, and the held-for-sale liabilities are primarily comprised of Accounts payable and Other current liabilities.

Results of discontinued operations are as follows:

	Three Months Ended December 31
(in millions)	2014			2013
Sales	$	8		$	17
(Loss) from discontinued operations before income taxes	(3		)	(4		)
Income tax benefit from discontinued operations	1			1

On November 22, 2013, the Company sold its subsidiary, Kaiser Optical Systems, Inc. (KOSI), a supplier of spectrographic instrumentation and applied holographic technology, to Endress+Hauser. The sale price, after post-closing adjustments for changes in working capital, was $23 million. This resulted in a pretax gain of $10 million, which was included in Other income, net during the three months ended December 31, 2013. The divestiture of this business is part of our strategy to reshape the Government Systems segment to align with the changing dynamics of the defense environment and focus on opportunities in addressed markets for the Company's core products and solutions. As part of the divestiture agreement, the Company entered into a long-term supply agreement with the buyer that allows the Company to continue purchasing certain products from KOSI after completion of the sale. As a result of this continuing involvement, the KOSI divestiture did not qualify for classification as a discontinued operation.

5. Receivables, Net

Receivables, net are summarized as follows:

(in millions)	December 31, 2014			September 30, 2014
Billed	$	764		$	758
Unbilled	456			485
Less progress payments	(164		)	(198		)
Total	1,056			1,045
Less allowance for doubtful accounts	(12		)	(12		)
Receivables, net	$	1,044		$	1,033

Receivables expected to be collected beyond the next twelve months are classified as long-term and are included within Other Assets. Receivables, net due from equity affiliates were $68 million and $76 million at December 31, 2014 and September 30, 2014, 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.

Less progress payments	(8		)	(8		)
Total	872			833
Pre-production engineering costs	907			876
Inventories, net	$	1,779		$	1,709

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 under long-term supply arrangements with the Company's customers. Pre-production engineering costs incurred pursuant to supply arrangements that do not contain contractual guarantees for reimbursement are expensed as incurred.

As a result of the ARINC acquisition, the Company has allocated $384 million to finite-lived intangible assets with a weighted average life of approximately 15 years and $47 million to indefinite-lived intangible assets.

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.

Investments in Equity Affiliates

Investments in equity affiliates primarily consist of seven joint ventures, which are accounted for under the equity method. Under the equity method of accounting for investments, the Company's proportionate share of 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.

All of the Company's joint ventures are 50 percent owned. For segment performance reporting purposes, Rockwell Collins’ share of earnings or losses of Rockwell Collins Elbit Systems of America (ESA), Data Link Solutions (DLS), Integrated Guidance Systems (IGS) and Quest Flight Training Limited are included in the operating results of the Government Systems segment.

respectively. The deferred portion of profit generated from sales to equity affiliates was $1 million at December 31, 2014 and $1 million at September 30, 2014.

Exchange and Rental Assets

Exchange and rental assets consist primarily of Company products that are either exchanged 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 methods and lives are reviewed periodically with any changes recorded on a prospective basis. Depreciation expense for exchange and rental assets was $2 million and $2 million for the three months ended December 31, 2014 and 2013, respectively.

10. Debt

Commercial Paper Program

Under the Company’s commercial paper program, the Company may sell up to $1 billion 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. The commercial paper program is supported by the Company's $1 billion five-year revolving credit facility. At December 31, 2014, short-term commercial paper borrowings outstanding were $831 million with a weighted-average interest rate and maturity period of 0.42 percent and 22 days, respectively. At September 30, 2014, short term commercial paper borrowings outstanding were $504 million with a weighted-average interest rate and maturity period of 0.32 percent and 29 days, respectively.

Revolving Credit Facilities

On September 24, 2013, the Company entered into new credit agreements to ensure adequate commercial paper borrowing capacity in anticipation of the Company's then pending ARINC acquisition and to meet other short-term cash requirements. The Company closed on these new revolving credit facilities on December 23, 2013, concurrent with the ARINC acquisition closing date. These new credit facilities consist of a five-year $1 billion credit facility that expires in December 2018 and a 364-day $200 million credit facility that expired in December 2014 and was not renewed. These agreements replaced the prior $850 million revolving credit facility that was terminated concurrently upon the closing of the new agreements.

The credit facilities include 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 equity impact on accumulated other comprehensive loss related to defined benefit retirement plans. The ratio was 44 percent as of December 31, 2014. The credit facilities also contain 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 these credit facilities 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, 2014 and September 30, 2014 there were no outstanding borrowings under these revolving credit facilities.

In addition, short-term credit facilities available to non-U.S. subsidiaries amounted to $41 million as of December 31, 2014, of which $12 million was utilized to support commitments in the form of commercial letters of credit. At

December 31, 2014 and September 30, 2014, there were no short-term borrowings outstanding under the Company’s non-U.S. subsidiaries’ credit facilities.

At December 31, 2014 and September 30, 2014, there were no significant commitment fees or compensating balance requirements under any of the Company’s credit facilities.

December 2013 Long-term Debt Issuances

On December 16, 2013, the Company issued $300 million of floating rate unsecured debt due December 15, 2016 (the 2016 Notes). The 2016 Notes bear annual interest at a rate equal to three-month LIBOR plus 0.35 percent. As of December 31, 2014 the quarterly interest rate was 0.59 percent. The rate resets quarterly. The net proceeds to the Company from the 2016 Notes, after deducting $1 million of debt issuance costs, were $299 million.

On December 16, 2013, the Company issued $400 million of 3.7 percent fixed rate unsecured debt due December 15, 2023 (the 2023 Notes). The net proceeds to the Company from the 2023 Notes, after deducting a $1 million discount and $3 million of debt issuance costs, were $396 million. In March 2014, the Company entered into interest rate swap contracts which effectively converted $200 million of the 2023 Notes to floating rate debt based on one-month LIBOR plus 0.94 percent.

On December 16, 2013, the Company issued $400 million of 4.8 percent fixed rate unsecured debt due December 15, 2043 (the 2043 Notes). The net proceeds to the Company from the 2043 Notes, after deducting a $2 million discount and $4 million of debt issuance costs, were $394 million.

The net proceeds after discounts and debt issuance costs from the December 16, 2013 debt issuances totaled $1,089 million. Approximately $900 million was used to finance the ARINC acquisition and approximately $200 million was used to refinance the 2013 Notes that matured on December 1, 2013. The remaining ARINC purchase price was funded using commercial paper proceeds.

Other 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).

In January 2010, the Company entered into interest rate swap contracts which effectively converted $150 million of the 2019 Notes to floating rate debt based on six-month LIBOR plus 1.235 percent. See Notes 16 and 17 for additional information relating to the interest rate swap contracts.

The 2043, 2023, 2021, 2019 and 2016 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 are recorded in Interest expense.

The 2043, 2023, 2021, 2019 and 2016 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, 2014 and September 30, 2014.

Pension Plan Funding

The Company’s objective with respect to the funding of its pension plans is to provide adequate assets for the payment of future benefits. Pursuant to this objective, the Company will fund its pension plans as required by governmental regulations and may consider discretionary contributions as conditions warrant. In October 2014, the Company voluntarily contributed $55 million to its U.S. qualified pension plan. There was no minimum statutory funding requirement for 2015 and the Company does not currently expect to make any additional discretionary contributions during 2015 to this plan. Furthermore, the Company is not required to make, and does not intend to make, any contributions to the ARINC pension plans during 2015. Any additional future contributions necessary to satisfy minimum statutory funding requirements are dependent upon actual plan asset returns, interest rates, and actuarial assumptions. Contributions to the non-U.S. plans and the U.S. non-qualified plan are expected to total $14 million in 2015.

ARINC Pension Plan and Other Retirement Benefits

ARINC sponsors two primary pension sub-plans: one for union employees and one for non-union employees. ARINC also provides postretirement health coverage for many of its current and former employees and postretirement

life insurance benefits for certain retirees. The ARINC pension and postretirement benefit obligations are included within Retirement Benefits as liabilities on the Company's Condensed Consolidated Statement of Financial Position as of December 31, 2014.

15. Income Taxes

At the end of each interim reporting period, the Company makes an estimate of the annual effective income tax rate. Tax items included in the annual effective income tax rate are pro-rated for the full year and tax items discrete to a specific quarter are included in the effective income tax rate for that quarter. The estimate used in providing for income taxes on a year-to-date basis may change in subsequent interim periods.

During the three months ended December 31, 2014 and 2013, the effective income tax rate from continuing operations was 22.5 percent and 27.2 percent, respectively. The lower current year effective income tax rate from continuing operations was primarily due to the retroactive extension of the Federal R&D Tax Credit which had previously expired on December 31, 2013, partially offset by the absence of the recognition of a tax benefit related to prior years' Extraterritorial Income Exclusion deductions. On December 19, 2014, the Tax Increase Prevention Act of 2014 was enacted, which retroactively reinstated and extended the Federal R&D Tax Credit from January 1, 2014 through December 31, 2014.

The Company's U.S. Federal income tax returns for the tax year ended September 30, 2011 and prior years have been audited by the IRS and are closed to further adjustments by the IRS. The IRS is currently auditing the Company's tax

returns for the years ended September 30, 2012 and 2013. ARINC's U.S. Federal income tax returns are currently under audit by the IRS for the tax years ended December 31, 2009 and December 31, 2012 and are closed to further adjustments by the IRS for all tax years ended December 31, 2008 and prior. The Company and ARINC are also currently under audit in various U.S. states and non-U.S. jurisdictions. The U.S. states and non-U.S. jurisdictions have statutes of limitations generally ranging from 3 to 5 years. The Company believes it has adequately provided for any tax adjustments that may result from the various audits.

The Company had net income tax payments of $23 million and $49 million during the three months ended December 31, 2014 and 2013, respectively.

The Company has gross unrecognized tax benefits recorded within Other Liabilities in the Condensed Consolidated Statement of Financial Position of $55 million and $48 million as of December 31, 2014 and September 30, 2014, respectively. The total amount of unrecognized tax benefits that, if recognized, would affect the effective income tax rate was $31 million and $25 million as of December 31, 2014 and September 30, 2014, 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 in the range of $0 to $1 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 $2 million and $1 million as of December 31, 2014 and September 30, 2014, respectively. The total amount of interest and penalties recorded as an expense or (income) within Income tax expense in the Condensed Consolidated Statement of Operations was $0 million for each of the three months ended December 31, 2014 and 2013, respectively.

16. Fair Value Measurements

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

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

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

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

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

The fair value of cash and cash equivalents and short-term debt approximates their carrying value due to the short-term nature of the instruments. These items are within Level 1 of the fair value hierarchy. Fair value information for all long-term debt is within Level 2 of the fair value hierarchy. The fair value of these financial instruments was 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.

17. Derivative Financial Instruments

Interest Rate Swaps

The Company manages its exposure to interest rate risk by maintaining a 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 March, 2014 the Company entered into three interest rate swap contracts (the 2023 Swaps) which expire on December 15, 2023 and effectively converted $200 million of the 2023 Notes to floating rate debt based on one-month LIBOR plus 0.94 percent.

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.

The Company designated the 2019 and 2023 Swaps (the Swaps) as fair value hedges. The 2019 and 2023 Swaps are recorded within Other Assets at a fair value of $24 million, offset by a fair value adjustment to Long-term Debt (Note 10) of $24 million at December 31, 2014. At September 30, 2014, the Swaps were recorded within Other Assets at a fair value of $18 million, offset by a fair value adjustment to Long-term Debt (Note 10) of $18 million. Cash payments or receipts between the Company and the counterparties to the Swaps are recorded as an adjustment to interest expense.

Forward Starting Interest Rate Swaps

In September 2013, the Company entered into forward starting interest rate swap agreements with combined notional values of $200 million to effectively lock in fixed interest rates on a portion of the long-term debt it incurred in December 2013 to refinance maturing debt and to fund the acquisition of ARINC. In October 2013, the Company entered into an additional $300 million notional value of forward starting interest rate swap agreements. These forward starting interest rate swaps were designated as cash flow hedges and were executed to hedge the risk of potentially higher benchmark U.S. Treasury bond yields on long-term debt with maturities ranging from 2023 to 2043 and fixed interest rates ranging between 2.8150 percent and 3.8775 percent. The forward starting interest rate swaps were terminated in December 2013 concurrent with the Company's debt issuance. Upon termination, the forward starting swaps were valued at a net loss of $2 million. This net loss has been deferred within Accumulated other comprehensive losses in the Condensed Consolidated Statement of Financial Position and will be amortized into interest expense over the life of the corresponding debt.

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, 2014 and September 30, 2014, the Company had outstanding foreign currency forward exchange contracts with notional amounts of $329 million and $575 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, 2014 and September 30, 2014 are as follows:

		Asset Derivatives

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, 2014. 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, 2014.

The Company did not have any hedges with credit-risk-related contingent features or that required the posting of collateral as of December 31, 2014. The cash flows from derivative contracts are recorded in operating activities in the Condensed Consolidated Statement of Cash Flows.

Cash flow hedges are de-designated 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 $6 million of net losses into earnings over the next 12 months. The maximum duration of a foreign currency cash flow hedge contract at December 31, 2014 was 67 months.

18. Guarantees and Indemnifications

Product warranty costs

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

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

Changes in estimates for prior years	—			(6		)
Foreign currency translation adjustments and other	(1		)	—
Balance at December 31	$	103		$	116

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, 2014, the outstanding loan balance was approximately $3 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, 2014, 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, 2014 were $280 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:

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.

24

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.

19. Environmental Matters

The Company is subject to federal, state and local regulations relating to the discharge of substances into the environment, the disposal of hazardous wastes and other activities affecting the environment that have had and will continue to have an impact on the Company’s manufacturing operations. These environmental protection regulations may require the investigation and remediation of environmental impairments at current and previously owned or leased properties. In addition, lawsuits, claims and proceedings have been asserted on occasion against the Company alleging violations of environmental protection regulations, or seeking remediation of alleged environmental impairments, principally at previously owned or leased properties. As of December 31, 2014, 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. The Company has recorded environmental reserves for this site of $6 million as of December 31, 2014, 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.

20. Legal Matters

The Company is subject to various lawsuits, claims and proceedings that have been or may be instituted or asserted against the Company relating to the conduct of the Company's business, including those pertaining to product liability, antitrust, intellectual property, safety and health, exporting and importing, contract, employment and regulatory matters. Although the outcome of these matters cannot be predicted with certainty and some lawsuits, claims or proceedings may be disposed of unfavorably to the Company, management believes there are no material pending legal proceedings.

21. Restructuring, Pension Settlement and Asset Impairment Charges, Net

In September 2014, the Company recorded pension settlement and restructuring charges totaling $9 million. This amount was comprised of (i) $5 million for pension settlement charges (included within Selling, general, and administrative expense) and (ii) $4 million for employee severance costs related to the consolidation and closure of two service centers as part of a plan to optimize the efficiency of the Company's global service center footprint. These severance costs were included within cost of sales. Through December 31, 2014, the Company has made cash payments of $7 million associated with these actions. As of December 31, 2014, approximately $2 million of employee severance costs remain to be paid in future periods.

During the year ended September 30, 2012, the Company recorded 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 the workforce in anticipation of the sequestration impacts on the U.S. defense budgets. Through December 31, 2014, the Company has made cash severance payments of approximately $31 million related to the 2012 restructuring action. As of December 31, 2014, $4 million of employee separation costs related to the 2012 action remains to be paid in future periods.

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

OVERVIEW AND OUTLOOK

We have a diversified and balanced business, serving both commercial and government markets. Our Commercial Systems business supplies aviation electronics systems, products and services to customers located throughout the world. The Commercial Systems customer base is comprised of OEMs of commercial air transport, business and regional aircraft, commercial airlines and business aircraft operators. Our Government Systems business provides avionics, communication products, surface solutions and navigation products to the U.S. Department of Defense, state and local governments, other government agencies, civil agencies, defense contractors and foreign ministries of defense around the world. These systems, products and services support airborne (fixed and rotary wing), ground and shipboard applications. 

On December 23, 2013, we completed our acquisition of ARINC for $1,405 million. The acquisition of ARINC was funded through a combination of new long-term debt issuances and commercial paper borrowings. In connection with this acquisition, a new Information Management Services business segment was formed. This new segment combines ARINC with the Company's legacy flight services business, which had previously been included in the Commercial Systems segment. The acquisition of ARINC expands our position as a leading provider of information management services. 

On December 19, 2014, the Tax Increase Prevention Act of 2014 was enacted, which retroactively reinstated and extended the Federal Research and Development Tax Credit (Federal R&D Tax Credit) from January 1, 2014 through December 31, 2014. This favorable tax credit had previously expired on December 31, 2013. As a result of this legislation, we now expect our effective income tax rate for 2015 to be in the range of 28 to 29 percent (from about 31 percent). We expect the retroactive extension of the Federal R&D Tax Credit will benefit our full fiscal year 2015 earnings per share guidance range by 20 cents.

During the first quarter of 2015, total revenues increased 16 percent, driven by the ARINC acquisition and a 9 percent increase in Commercial Systems revenues. Diluted earnings per share from continuing operations increased 29 percent to $1.26, due to the benefit from higher earnings in Commercial Systems and Government Systems, the ARINC acquisition and the retroactive benefit of the Federal R&D Tax Credit.

The following table is a summary of our company's updated fiscal year 2015 guidance for continuing operations.

• total sales in the range of $5.2 billion to $5.3 billion

• diluted earnings per share in the range of $5.10 to $5.30 (updated from $4.90 to $5.10)

• cash provided by operating activities in the range of $700 million to $800 million (updated from $675 million to $775 million)

• capital expenditures of about $200 million

• total research and development investment of about $1 billion (updated from about $950 million) ⁽¹⁾ 

⁽¹⁾ Total research and development (R&D) 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 of results of operations is based on reported financial results for the three months ended December 31, 2014 and 2013 and should be read in conjunction with our condensed consolidated financial statements and notes thereto in Item 1 of Part I of this quarterly report.

As discussed in Note 4 of the Notes to Condensed Consolidated Financial Statements, the results of Datapath and ASES have been accounted for as discontinued operations for all periods presented. Unless otherwise noted, disclosures pertain to our continuing operations.

Sales

	Three Months Ended December 31
(in millions)	2014			2013
Total Sales	$	1,226		$	1,054
Percent increase	16		%

Total sales increased $172 million, or 16 percent for the quarter ended December 31, 2014, as compared to the quarter ended December 31, 2013. ARINC, which was acquired on December 23, 2013, contributed $131 million, or 12 percent, to the overall revenue growth. Commercial Systems sales increased by $47 million and Government Systems sales decreased by $6 million. Refer to the Commercial Systems, Government Systems and Information Management Services sections of the Segment Financial Results below for a detailed discussion of sales in the first quarter of 2015 as compared to the same period last year.

Cost of Sales

(in millions)	2014			2013
Total cost of sales	$	857		$	737
Percent of total sales	69.9		%	69.9		%

Cost of sales consists of all costs incurred to design and manufacture our products and provide our services and includes R&D, raw material, labor, facility, product warranty, depreciation, amortization, service and support and other related expenses. Total cost of sales increased $120 million, or 16 percent, primarily due to the following:

• $91 million from the ARINC business, which was acquired on December 23, 2013

• $30 million from higher sales volume in Commercial Systems

Research and development expense

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

	Three Months Ended December 31
(in millions)	2014			2013
Customer-funded:
Commercial Systems	$	40		$	22
Government Systems	89			89

Total research and development expense	$	200		$	176
Percent of total sales	16.3		%	16.7		%

⁽¹⁾ Research and development expenses for the Information Management Services segment, including the ARINC acquisition, do not include costs of internally developed software and other costs associated with the expansion and construction of network-related assets. These costs are capitalized as Property on the Condensed Consolidated Statement of Financial Position.

29

We make significant investments in research and development to allow our customers to benefit from the latest technological advancements. Total R&D expense is comprised of both company-funded and customer-funded R&D expenditures. In addition to the R&D expenditures shown in the table above, we capitalize in inventory 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. Pre-production engineering costs are then amortized over their useful lives. This amortization cost is included within customer-funded R&D expense and totaled $12 million and $6 million for the three months ended December 31, 2014 and 2013, respectively. Refer to Note 6 of the Notes to Condensed Consolidated Financial Statements for further discussion of our investments in pre-production engineering effort.

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 the development of new products and the improvement of existing products and are expensed as incurred. Company-funded R&D expense consists primarily of payroll-related expenses of employees engaged in R&D activities, engineering-related product materials and equipment and subcontracting costs.

Total R&D expense for the three months ended December 31, 2014 increased $24 million from the same period last year. The customer-funded portion of R&D expense increased by $20 million primarily due to increased costs associated with various international programs in Commercial Systems, as well as higher amortization of pre-production engineering costs in Commercial Systems and Government Systems. The $4 million increase in company-funded R&D was principally driven by an increase in R&D efforts associated with certain Government Systems programs.

In addition to the R&D expenses above, our investments in pre-production engineering programs capitalized within inventory had a net $31 million increase driven by effort on the Boeing 737 MAX platform and Bombardier CSeries and Global 7000/8000 programs. Refer to Note 6 of the Notes to Condensed Consolidated Financial Statements for further discussion of our incremental investments in pre-production engineering effort.

Selling, General and Administrative Expenses

	Three Months Ended December 31
(in millions)	2014			2013
Selling, general and administrative expenses	$	137		$	134
Percent of total sales	11.2		%	12.7		%

Selling, general and administrative (SG&A) expenses consist primarily of personnel, facility and other expenses related to employees not directly engaged in manufacturing or R&D 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, 2014 increased $3 million, or 2 percent, primarily due to:

• $19 million of SG&A costs from the acquired ARINC business

• partially offset by the absence of $12 million of transaction costs for legal, accounting and advisory fees resulting from the ARINC acquisition

• the remaining net decrease of $4 million was attributable to lower bid and proposal costs as well as other cost savings initiatives

30

Interest Expense

	Three Months Ended December 31
(in millions)	2014			2013
Interest expense	$	15		$	12
Percent increase	25		%

Interest expense increased by $3 million in the quarter ended December 31, 2014 compared to the quarter ended December 31, 2013, primarily due to incremental interest on the new long-term debt and commercial paper we issued to fund the ARINC acquisition.

See Note 10 of the Notes to Condensed Consolidated Financial Statements for more detail regarding outstanding debt.

Net Income and Diluted Earnings Per Share

	Three Months Ended December 31
(in millions, except per share amounts)	2014			2013

Diluted earnings per share	$	1.24		$	0.96
Weighted average diluted common shares	134.5			136.7

Income from continuing operations, net of taxes, for the quarter ended December 31, 2014 was $169 million, up 26 percent, or $35 million, from the $134 million in income from continuing operations, net of taxes, reported for the quarter ended December 31, 2013. Diluted earnings per share from continuing operations increased 29 percent to $1.26 during this same time period. The rate of increase in diluted earnings per share from continuing operations was more than the rate of increase in income from continuing operations, net of taxes, because of the favorable impacts from our share repurchase program.

Income from continuing operations, net of taxes, and earnings per share during the quarter ended December 31, 2014 benefited from the higher operating earnings across all segments as well as a lower effective income tax rate.

Commercial Systems Financial Results

Commercial Systems Sales

The following table presents Commercial Systems sales by product category:

	Three Months Ended December 31
(in millions)	2014			2013
Air transport aviation electronics:
Original equipment	$	191		$	157
Aftermarket	131			128
Wide-body in-flight entertainment	16			19
Total air transport aviation electronics	338			304

Original equipment	140			129
Aftermarket	90			88
Total business and regional aviation electronics	230			217
Total	$	568		$	521
Percent increase	9		%

Total air transport aviation electronics sales increased $34 million, or 11 percent, primarily due to the following:

• original equipment sales increased $34 million, or 22 percent, primarily due to higher OEM production rates, improved share of airline selectable equipment and higher customer funded development program sales

• aftermarket sales increased $3 million, or 2 percent, primarily driven by higher service and support activities and higher regulatory mandate upgrades, partially offset by the absence of a large delivery of spare parts for the Boeing 787 GoldCare program in the prior year

• wide-body IFE sales decreased $3 million, or 16 percent, as airlines continued to decommission their legacy IFE systems and no longer require our services, given the Company's strategic decision announced in 2005 to cease investment in this product area

Total business and regional aviation electronics sales increased $13 million, or 6 percent, primarily due to the following:

• original equipment sales increased $11 million, or 9 percent, primarily due to higher customer funded development program revenues

• aftermarket sales increased $2 million, or 2 percent, driven by higher service and support activities

Percent of sales	22.0		%	21.3		%

Commercial Systems operating earnings increased $14 million, or 13 percent, primarily due to the $47 million increase in sales discussed in the Commercial Systems sales section above, which resulted in a $30 million increase in cost and incremental earnings of $17 million, or 36 percent of the higher sales volume. The margins on the incremental earnings were tempered by sales growth in customer funded development programs.

Segment operating earnings	$	106		$	105
Percent of sales	20.8		%	20.4		%

Government Systems operating earnings increased $1 million, or 1 percent, primarily due to the following:

• a more favorable mix of higher margin hardware revenues

• partially offset by the absence of a favorable warranty reserve adjustment that occurred in the prior year

The increase in Government Systems operating earnings as a percent of sales was due to a more favorable mix, partially offset by higher warranty expense.

Information Management Services Sales

The following table presents Information Management Services sales:

	Three Months Ended December 31
(in millions)	2014		2013
Sales	$	149	$	18

Total Information Management Services sales increased $131 million, due to the acquisition of ARINC, which occurred on December 23, 2013.

Note 3 of the Notes to Condensed Consolidated Financial Statements presents supplemental pro-forma financial data as if the acquisition of ARINC had been completed as of the beginning of our prior year, or on October 1, 2013. The pro-forma data included in Note 3 combines our consolidated results with the stand-alone results of ARINC for the pre-acquisition periods. The pro-forma data excludes the results of ASES, which we intend to divest. The supplemental pro-forma data is not necessarily indicative of results that actually would have occurred had the acquisition truly been consummated on October 1, 2013. On a pro-forma basis, sales for the Information Management Services segment would be $149 million and $124 million for the three months ended December 31, 2014 and 2013, respectively. The $25 million, or 20 percent, increase in the pro-forma sales was driven by double-digit sales growth in aviation related sales, including GLOBALink^SM and ARINCDirect^SM as well as higher rail related sales due to certain unfavorable contract adjustments recorded in the first quarter of fiscal 2014. Refer to Note 3 of the Notes to Condensed Consolidated Financial Statements for further pro-forma disclosures.

Pension Benefits

In 2003, we amended our U.S. qualified and non-qualified pension plans 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. Additionally, the ARINC defined benefit pension plan that we assumed in connection with the December 2013 acquisition is also largely frozen to new participants who are not covered by collective bargaining agreements. The ARINC pension plan was approximately 99 percent funded at the acquisition date.

We expect defined benefit pension income of $5 million in 2015, compared to $10 million of pension expense in 2014.

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

During the three months ended December 31, 2014, we made a $55 million voluntary contribution to our legacy U.S. qualified pension plan. There is no minimum statutory funding requirement for 2015 and we do not currently expect to make any additional discretionary contributions during 2015 to this plan. Furthermore, we are not required to make, and do not intend to make, any contributions to the ARINC pension plans during 2015. Any additional future contributions necessary to satisfy minimum statutory funding requirements are dependent upon actual plan asset returns and interest rates. Contributions to our non-U.S. plans and our U.S. non-qualified plan are expected to total $14 million in 2015.

Other Retirement Benefits

We expect other retirement benefits expense of approximately $11 million in 2015. This compares to 2014 expense of $10 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 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, 2014 and 2013, the effective income tax rate from continuing operations was 22.5 percent and 27.2 percent, respectively. The lower current year effective income tax rate from continuing operations was primarily due to the retroactive extension of the Federal R&D Tax Credit which had previously expired on December 31, 2013, partially offset by the absence of the recognition of a tax benefit related to prior years' Extraterritorial Income Exclusion deductions. On December 19, 2014, the Tax Increase Prevention Act of 2014 was enacted, which retroactively reinstated and extended the Federal R&D Tax Credit from January 1, 2014 through December 31, 2014.

For fiscal year 2015, our effective income tax rate is projected to be in the range of 28 to 29 percent which includes the retroactive extension of the Federal R&D Tax Credit.

FINANCIAL CONDITION AND LIQUIDITY

Cash Flow Summary

Our ability to generate significant 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 our fourth quarter. We expect this trend to continue in the future.

Operating Activities

	Three Months Ended December 31
(in millions)	2014			2013
Cash (used for) operating activities from continuing operations	$	(60	)	$	(24	)

The $36 million increase in cash used for operating activities during the three months ended December 31, 2014 compared to the same period last year was primarily due to the following:

• receivables outstanding increased $15 million during three months ended December 31, 2014 from September 30, 2014, compared to a decrease of $86 million during the same period in the prior year due to timing of collections from customers

• the above item was partially offset by $34 million of higher earnings from continuing operations before income taxes, of which $19 million is attributable to the acquisition of ARINC

• in addition, cash payments for income taxes decreased $26 million to $23 million during the first three months of fiscal year 2015 compared to $49 million during the same period last year. The decrease in cash used for income tax payments is primarily due to the timing of recognizing a deduction for contributions to our pension plan

Investing Activities

	Three Months Ended December 31
(in millions)	2014			2013
Cash (used for) investing activities from continuing operations	$	(76	)	$	(1,434	)

Cash used for investing activities for the quarter ended December 31, 2014 decreased by $1,358 million compared to the quarter ended December 31, 2013 primarily due to the following:

• in December 2013, we paid $1.42 billion for the acquisition of ARINC

• the above item was partially offset by a $24 million increase in cash payments for property additions for the three months ended December 31, 2014, compared to the same period last year

• in addition, we received $24 million in proceeds from the divestiture of our KOSI business in November 2013. We had no business divestitures during the same period of this year

36

Financing Activities

	Three Months Ended December 31
(in millions)	2014		2013
Cash provided by financing activities from continuing operations	$	138	$	1,517

The $1,379 million decrease in cash provided by financing activities during the quarter ended December 31, 2014 compared to the quarter ended December 31, 2013 was primarily due to the following:

• in December 2013, we received net proceeds of $1.089 billion from the issuance of long-term debt. A portion of these proceeds were used to finance the acquisition of ARINC and the remainder was used to refinance $200 million of long-term debt that matured in December 2013

• net proceeds from short-term commercial paper borrowing decreased $355 million. During the three months ended December 31, 2014, net proceeds from short-term commercial paper borrowings were $327 million, compared to net proceeds of $682 million during the same period last year. The incrementally higher proceeds in the prior year were used primarily to finance the acquisition of ARINC

• cash repurchases of common stock increased by $151 million to $173 million during the quarter ended December 31, 2014, compared to $22 million repurchased during the same period last year

Financial Condition and Liquidity

We maintain a capital structure that we believe enables us sufficient access to credit markets. When combined with our ability to generate strong levels of cash flow from our operations, this capital structure has provided the strength and flexibility necessary to pursue strategic growth opportunities and to return value to our shareowners.

A comparison of key elements of our financial condition as of December 31, 2014 and September 30, 2014 are as follows:

(in millions)	December 31, 2014			September 30, 2014
Cash and cash equivalents	$	315		$	323
Short-term debt	(831		)	(504		)
Long-term debt, net	$	(1,670	)	$	(1,663	)
Net debt (1)	(2,186		)	(1,844		)
Total equity	$	1,870		$	1,889
Debt to total capitalization (2)	57		%	53		%
Net debt to total capitalization (3)	54		%	49		%

⁽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.On December 23, 2013, we acquired ARINC for $1,405 million. This acquisition was funded through a combination of new long-term debt and commercial paper borrowings. The proceeds from the long-term debt issuance totaled $1,089 million, of which approximately $900 million was used for the ARINC acquisition, with the remaining portion used to effectively refinance the $200 million unsecured debt due December 1, 2013. The balance of the ARINC purchase price was funded with commercial paper issuances which we intend to pay down over the next few years using our operating cash flow. While the incremental debt resulting from the acquisition of ARINC increased our leverage, we expect to maintain our investment grade credit ratings and to have continued access to the credit markets.

As of December 31, 2014, approximately 90 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 potential 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

37

commercial paper. Under our commercial paper program, we may sell up to $1,000 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, 2014, short-term commercial paper borrowings outstanding were $831 million with a weighted-average interest rate and maturity period of 0.42 percent and 22 days, respectively. At September 30, 2014, short-term commercial paper borrowings outstanding were $504 million with a weighted-average interest rate and maturity period of 0.32 percent and 29 days, respectively. The maximum amount of short-term commercial paper borrowings outstanding during the three months ended December 31, 2014 was $881 million.

On September 24, 2013, the Company entered into new credit agreements to ensure adequate commercial paper borrowing capacity in anticipation of the Company's then pending ARINC acquisition and to meet other short-term cash requirements. The Company closed on these new revolving credit facilities on December 23, 2013, concurrent with the ARINC acquisition closing date. These new credit facilities consist of a five-year $1 billion credit facility that expires in December 2018 and a 364-day $200 million credit facility that expired in December 2014. These agreements replace the prior $850 million revolving credit facility that was terminated concurrently upon the closing of the new agreements. These revolving credit facilities are in place principally to support our commercial paper program. The credit facilities include one financial covenant that requires us to maintain a consolidated debt to total capitalization ratio of not greater than 60 percent. The ratio excludes the equity impact on accumulated other comprehensive loss related to defined benefit retirement plans. Our debt to total capitalization ratio on December 31, 2014 based on this financial covenant was 44 percent.

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, nor do we have any current plans to do so, 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. Our strong credit ratings have enabled continued access to both short and long-term credit markets. If our credit ratings were to be adjusted downward by the rating agencies, the implications of such actions could include impairment or elimination of our access to credit markets and an increase in the cost of borrowing. The following is a summary of our credit ratings as of December 31, 2014:

Credit Rating Agency	Short-Term Rating	Long-Term Rating	Outlook
Fitch Ratings	F1	A	Negative
Moody’s Investors Service	P-2	A3	Stable
Standard & Poor’s	A-2	A-	Stable

We were in compliance with all debt covenants at December 31, 2014 and September 30, 2014.

CRITICAL ACCOUNTING POLICIES

Preparation of our financial statements in accordance with accounting principles generally accepted in the United States of America requires management of Rockwell Collins to make estimates, judgments and assumptions that affect our financial condition and results of operations that are reported in the accompanying consolidated financial statements as well as the related disclosure of assets and liabilities contingent upon future events. The critical accounting policies used in preparation of our financial statements are described in Management's Discussion and Analysis in our Annual Report on Form 10-K for the year ended September 30, 2014. 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.

38

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 awards of domestic and internal contracts; delays in customer programs; unanticipated impacts of sequestration and other provisions of the Budget Control Act of 2011 as modified by the Bipartisan Budget Act of 2013; the discontinuance of support for military transformation and modernization programs; potential impact of oil price volatility on the commercial aerospace industry; the impact of terrorist events on the commercial aerospace industry; declining defense budgets results from budget deficits in the U.S. and abroad; changes in domestic and foreign government spending, budgetary, procurement and trade policies adverse to our business; market acceptance of our new and existing technologies, products and services; reliability of and customer satisfaction with our products and services; potential unavailability of our mission-critical data and voice communication networks; favorable outcomes on or potential cancellation or restructuring of contracts, orders or program priorities by our customers; recruitment and retention of qualified personnel; regulatory restrictions on air travel due to environmental concerns; effective negotiation of collective bargaining agreements by us, our customers, and our suppliers; 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 our internal performance plans such as our productivity and quality improvements and cost reduction initiatives; achievement of ARINC integration and synergy plans as well as our other 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.

At December 31, 2014, we had the following unsecured long-term debt obligations:

	December 31, 2014
(in millions)	Interest Rate	Carrying Value		Fair Value
$400 Notes due 2043	4.80%	$	398	$	470
$400 Notes due 2023	3.70%	399		423
$250 Notes due 2021	3.10%	250		257
$300 Notes due 2019	5.25%	299		338
$300 Notes due 2016	3 month LIBOR plus 0.35%	300		300

In March 2014, we entered into interest rate swap contracts which effectively converted $200 million of the Notes due 2023 to floating rate debt based on one month LIBOR plus 0.94 percent.

In January 2010, we entered into interest rate swap contracts which effectively converted $150 million of the Notes due 2019 to floating rate debt based on six month LIBOR plus 1.235 percent.

A hypothetical 10 percent increase in average market interest rates would have decreased the fair value of our long-term fixed rate debt, exclusive of the effects of the interest rate swap contracts, by $33 million. A hypothetical 10 percent decrease in average market interest rates would have increased the fair value of our long-term fixed rate debt, exclusive of the effects of the interest rate swap contracts, by $34 million. The fair value of the $350 million notional value of interest rate swap contracts was a $24 million net asset at December 31, 2014. A hypothetical 10 percent increase or decrease in average market interest

39

rates would decrease or increase the fair value of our interest rate swap contracts by $4 million. Our results of operations are affected by changes in market interest rates related to variable rate debt. Inclusive of the effect of the interest rate swaps, a hypothetical 10 percent increase or decrease in average market interest rates would not have a material effect on our operations or cash flows. For more information related to outstanding debt obligations and derivative financial instruments, see Notes 10, 16 and 17 in the 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 $329 million and $575 million at December 31, 2014 and September 30, 2014, 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 was a $7 million net liability at December 31, 2014 and a $3 million net liability at September 30, 2014. A 10 percent increase in the value of the U.S. dollar against all currencies would decrease the fair value of our foreign currency contracts at December 31, 2014 by $2 million. A 10 percent decrease in the value of the U.S. dollar against all currencies would increase the fair value of our foreign currency contracts at December 31, 2014 by $3 million. For more information related to outstanding currency forward exchange contracts, see Notes 16 and 17 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, 2014, 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, 2014 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 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.

• As to an additional one-third (rounded to the nearest whole number) of the Options on the second anniversary of the Grant Date, and

• As to the balance of the Options on the third anniversary of the Grant Date.

Subject to the terms of this Agreement, once an Option vests, it may be exercised until the tenth anniversary of the Grant Date. Options may be exercised in whole or in part (but only for a whole number of shares) and at one time or from time to time.

2.Termination of Employment Rules

Death

(a) If your employment by the Company or a Subsidiary terminates as a result of your death, then Options not then vested shall immediately vest on the date of your death and all outstanding Options shall remain exercisable (by any person who holds the Options as permitted by Section 5) and not expire until the earlier of (1) the third anniversary of your death and (2) the tenth anniversary of the Grant Date.

Other than Death

(b) Set forth below are the rules that apply if your employment by the Company or a Subsidiary terminates other than by reason of death.

(ii) Cause. If your employment is terminated for Cause, the Options shall immediately expire (regardless if they were vested) upon your termination date;

(iii) Retirement. If your employment terminates by reason of your Retirement on or after the first anniversary of the Grant Date, you (or any person who holds the Options as permitted by Section 5) may exercise Options that vested on or prior to the date of your Retirement and such Options shall not expire until the earlier of (1) the fifth anniversary of your Retirement date and (2) the tenth anniversary of the Grant Date. Options that were not vested prior to your Retirement shall continue to vest and become exercisable in accordance with the schedule outlined in Section 1 despite the fact that your employment terminated as a result of your Retirement. You (or any person who holds the Options as permitted by Section 5) may exercise Options that vest after your Retirement and such Options shall not expire until the earlier of (1) the fifth anniversary of your Retirement and (2) the tenth anniversary of the Grant Date; and

(v) Transfers A transfer of employment between the Company and a Subsidiary shall not constitute a termination of employment.

Special Rules After a Change of Control/Divestiture

2

(d) Notwithstanding any other provision of this Agreement to the contrary, if your principal employer is a Subsidiary, and your principal employer ceases to be a Subsidiary and your employment with the Company terminates as a result (the date of such cessation, is herein called the Divestiture Date), then following the Divestiture Date, Options not then vested shall immediately vest and all Options shall remain exercisable and not expire until the earlier of (1) the third anniversary of the Divestiture Date and (2) the tenth anniversary of the Grant Date.

(e) Subject to protections that may apply upon the occurrence of a Change of Control as noted in the definitions of Cause and Good Reason, a termination of employment will be deemed to be the day that notice of termination is provided (whether by your employer for any reason or by you upon resignation).

3.Exercise Procedure

To exercise Options, you must complete the transaction through our administrative agent’s website (currently www.netbenefits.fidelity.com) or call the toll free number provided to you (if you are an executive officer of the Company at the time of exercise of the Options you must call the toll free number to exercise Options and comply with any Company pre-clearance procedures), specifying the number of Options being exercised, together with payment of the full exercise price. You must deliver any documents associated with the exercise as the administrative agent may require. In no event may a fraction of a share be exercised or acquired. You must also pay any taxes or other amounts required to be withheld or otherwise due in connection with the exercise as provided in Section 4 of this Agreement. If full payment of the exercise price and any such tax or other amounts is not made, you (for yourself and on behalf of any other person who becomes entitled to exercise the Options) authorize the Company and your employer, in their discretion, to set off against salary payments or other amounts due to you (or the other person entitled to exercise the Options) any balance remaining unpaid.

From time to time, your ability to exercise Options which would otherwise be exercisable may also be restricted and Stock may not be issued, if in the reasonable good faith opinion of the Company’s General Counsel, this is necessary or advisable in order to ensure compliance with applicable laws, rules or regulations.

4.Withholding

(a) As a condition to the grant, vesting and exercise of the Options, the Company, your employer or the administrative agent shall have the right in whole or in part, to deduct from any payment to be made to you by the Company, your employer or the administrative agent an amount equal to the taxes, social contributions, and/or other charges required to be withheld or otherwise applicable by law with respect to the Options or Stock or to require you (or any other person entitled to the Options) to pay to it an amount sufficient to provide for any such taxes, social charges and/or other charges. You agree (for yourself and on behalf of any other person who becomes entitled to the Options or to the Stock) that if the Company, your employer or the administrative agent elects to require you (or such other person) to remit an amount sufficient to pay such taxes, social contributions, and/or other charges, you (or such other person) must remit that amount within three business days after such amount is due. If such payment is not made, the Company and your employer, in their discretion, shall have the same right of set-off as provided under Section 3 above.

(b) You acknowledge and agree that you are solely responsible for any and all taxes, social contributions, and/ or other charges that may be assessed by any taxing authority in the United States or any other jurisdiction arising from or related to the Options or the Stock or dividends (if any), that such amounts may exceed the amount actually withheld by the Company, your employer or the administrative agent, and that neither the Company nor any affiliate is liable for any such assessments. You are solely responsible for all relevant documentation that may be required of you in relation to the Options, such as but not limited to personal income tax returns or reporting statements in relation to the grant, vesting, or exercise of the Options, the holding or the subsequent sale of any Stock acquired on exercise, and the receipt of dividends. You acknowledge and agree that the Company makes no represenatations regarding the treatment of taxes, social contributions, or other charges and does not commit to and is under no obligation to structure the terms of the Plan or any award to reduce or eliminate your liability for any income taxes, social contributions, or other charges or achieve any particular tax result. Further, if you become subject to tax in more than one jurisdiction, the Company, your employer, or the admininstrative agent may be required to withhold or account for such amounts in more than one jurisdiction. Consult a tax or financial advisor if you have any questions.

5.Transferability; Nonassignability

You are not entitled to transfer the Options except by will or by the laws of descent and distribution.

Exhibit 10-a-2

ROCKWELL COLLINS, INC.

PERFORMANCE SHARE AGREEMENT

[Date]

We are pleased to confirm that, as a key employee of Rockwell Collins, Inc. or one of its subsidiaries (collectively, “Rockwell Collins” or the “Company”), you have been granted performance shares denominated in shares of the Company’s common stock. You have been granted the number of target shares set forth in the letter to you from Robert K. Ortberg dated [Date] (the “Performance Shares”) pursuant to this agreement (this “Agreement”) and under the Rockwell Collins [2006 or 2015, as applicable] Long-Term Incentives Plan, as amended (the “Plan”).

The grant of Performance Shares pursuant to this Agreement is not effective or enforceable until you properly acknowledge your acceptance of this Agreement by completing the electronic acceptance of this Agreement. Upon acceptance, the Agreement will be deemed effective as of [Date]. If you do not acknowledge your acceptance of this Agreement on or before [Date plus 6 months], the Performance Shares will be forfeited. If you reside outside the United States, the Company may require you to complete a written acceptance within this time period in lieu of an electronic acceptance.

Any payout of your Performance Shares will be based on the Company’s achievement of its Cumulative Sales goal and its Return on Sales goal, each measured over the Company’s 20[xx] through 20[xx] fiscal years (the “Performance Period”). These goals are set forth in Exhibit A attached hereto. The payout, if any, will be subject to further adjustment based upon the Company’s Total Shareowner Return (TSR) percentile relative to a peer group, as specified below. The terms and conditions of these Performance Shares are as set forth below.

The following is summary of the treatment of the Performance Shares in certain events. The summary is qualified in its entirety by the terms of the Agreement that follow.

Event	Treatment of Performance Shares
Death, Disability & Retirement (attained age 55 at time of termination)	Entitled to a pro rata payment of any Performance Shares earned. Payment occurs at the end of Performance Period.
Qualifying Termination after a Change of Control/Divestiture	Performance Shares paid out at target multiplied by the average payout over the prior three completed performance periods.
Other Terminations/Detrimental Activity	Performance Shares forfeited.

1. Confirmation of Award. This Agreement, together with the letter to you from Robert K. Ortberg referenced above, confirms your award in accordance with the terms as set forth herein.

2. Amount Payable Pursuant to Awards. Subject to the provisions of this Agreement, the shares of the Company’s common stock (“Common Stock”), if any, payable to you pursuant to your Performance Shares shall be calculated as follows:

(a) Determine the percentage, which can range from 0-80%, attributable to the Company’s achievement of its Cumulative Sales goal over the Performance Period as set forth on Exhibit A attached hereto (the “Cumulative Sales Percentage”). If the Cumulative Sales results that are achieved fall between the performance levels specified in Exhibit A, the percentage will be interpolated consistent with the range in which the Cumulative Sales falls as conclusively determined by the committee of the Board of Directors of the Company administering the Plan (which committee is herein called the “Committee” and which, on the date hereof, is the Compensation Committee). Fractional percentages will be rounded to the nearest whole number.

(b) Determine the percentage, which can range from 0-120%, attributable to the Company’s achievement of its Return on Sales goal over the Performance Period as set forth on Exhibit A attached hereto (the “Return on Sales Percentage”). If the Return on Sales results that are achieved fall between the performance levels specified in Exhibit A, the percentage will be interpolated consistent with the manner described above in 2(a). Fractional percentages will be rounded to the nearest whole number.

1

(c) Determine the TSR percentage, which can range between 80-120%, attributable to the Company’s TSR (as determined pursuant to Section 3) percentile performance relative to the peers as set forth on Exhibit A attached hereto (the “TSR Percentage”).

(d) Add the Cumulative Sales Percentage to the Return on Sales Percentage and multiply this sum by the TSR Percentage (such result, the “Final Award Percentage”).The Final Award Percentage will be rounded to the nearest whole percentage.

(e) To determine the number of Performance Shares, if any, that are payable, multiply the Final Award Percentage by the target shares specified in Mr. Ortberg’s letter to you referenced above.

Subject to the provisions of this Agreement, the amount payable to you pursuant to the Performance Shares with respect to the Performance Period shall be paid in shares of Common Stock, less shares to be withheld for taxes and/or other amounts as described below in Section 16, as soon as practicable after the end of the Performance Period and after receipt of the accountant’s letter for the Performance Period pursuant to Section 13, and in any event within the calendar year within which the Performance Period ends. Unless otherwise provided in Section 6 below and subject to applicable law, you will not be considered “vested” in the Performance Shares and will not be entitled to any payment thereunder unless you are employed as of the last day of the Performance Period.

The Performance Shares represent the Company’s unfunded and unsecured promise to issue shares of Common Stock at a future date, subject to the terms of this Agreement and the Plan. You have no rights under the Performance Shares or this Agreement other than the rights of a general unsecured creditor of the Company. Until the distribution of any Common Stock after vesting is evidenced in book entry form at the transfer agent, is placed into a brokerage account or a stock certificate is issued, you shall not have, with respect to the Performance Shares, rights to vote or receive dividends or any other rights as a shareowner.

3. Definitions and Determination of Financial Performance. “Cumulative Sales” means, for the Performance Period, the total sales as reported by the Company in its audited financial statements. “Return on Sales” means, for the Performance Period, the rate determined by dividing net income by sales. Both net income and sales will be the three year cumulative values as reported in the Company’s audited financial statements after adjusting for extraordinary income and expense items.

If a divestiture occurs during the Performance Period, adjustments will be made as follows:

(1) the Company’s annual sales and net income in each fiscal year of the Performance Period will include (without duplication) an amount equal to the divested business’ sales and net income (loss) in the full twelve month period completed immediately prior to the month in which the closing date of the divestiture occurs; and

(2) the gain or loss on divestiture shall be excluded from net income for the Performance Period.

If an acquisition occurs during the Performance Period, and the acquired business’ sales are less than 10% of the Company’s sales as reported over the Company’s last full four fiscal quarters, adjustments for each such acquisition will be made as follows:

(1) the Company’s sales and net income in the fiscal year during the Performance Period in which the acquisition closes will exclude the acquired business’ sales and net income (loss) results for the period of such fiscal year following the acquisition’s closing date;

(2)the Company’s sales in each fiscal year during the Performance Period subsequent to the year in which the acquisition closes will be reduced by an amount equal to the acquired business’ sales results for the full twelve month period ending with the Company’s first fiscal year end that occurs after the date of the acquisition;

(3)the Company’s net income in each fiscal year during the Performance Period subsequent to the year in which the acquisition closes will exclude an amount equal the net income (loss) of the acquired business in the full twelve month period ending prior to the acquisition’s closing date (as reflected in the base case scenario included in the Company’s final decision point review process for the acquisition); and

(4) the “fair value” expenses of an acquisition will be adjusted for purposes of calculating net income, including an addition to net income to offset the amortization of acquired intangibles and an addition to net income to offset for the lost opportunity to earn interest on invested funds (equal to the imputed interest on the net cost of the acquisition over the

2

period of Performance Period following the closing date of the acquisition, calculated using the average annual U.S. overnight LIBOR during that period).

The Committee reserves its discretion pursuant to Section 10 below to make necessary or appropriate adjustments to the definitions and measures or otherwise for acquisitions, divestitures and other matters referenced in Section 10.

TSR is measured by adding (i) the total stock price growth for the Performance Period, measured by comparing the average stock price during the Company’s fiscal October 20XX (i.e., from [date] to [date]) to the average stock price during the Company’s fiscal September 20XX (i.e., from [date] to [date]), and (ii) dividends paid during the Performance Period, measured as if reinvested in stock at the payment date. In the event of substantial changes causing an inability to calculate TSR for one or more of the peer companies listed on the attached Exhibit A (or in the event of spinoffs or similar transactions causing a peer company to split into two or more peer companies), the list of peer companies shall be adjusted accordingly to take such events into account.

In connection with the receipt of the accountant's letter for the Performance Period pursuant to Section 13, the Committee shall determine the Cumulative Sales, Return on Sales, the TSR results and percentile rankingand the Final Award Percentage for the Performance Period after taking into account any adjustment as contemplated in Section 10.

4. Payment of Performance Shares Denominated in Shares of Common Stock. The Performance Shares denominated in shares of Common Stock are payable in shares of the Company’s Common Stock; provided, however, that the Committee may, in its sole discretion, make a cash payment equal to the Fair Market Value of shares of Common Stock otherwise required to be issued. The Company may issue shares of Common Stock in book entry form in connection with the payout of Performance Shares. In lieu of fractional shares the Company may determine, in its sole discretion, to pay cash or to round such shares to the closest whole number. The future value of the shares of Common Stock underlying the Performance Shares is unknown and cannot be predicted with certainty.

5. Transferability of Award. The Performance Shares shall not be transferable by you except by will or by the laws of descent and distribution.

6. Termination of Employment for Death, Disability or Retirement. If your employment by the Company terminates during the Performance Period by reason of your death, disability or retirement (defined as you are age 55 or older at time of termination), you will continue to be eligible to receive a payment, if any, that would otherwise be payable pursuant to Section 2, but any such amount shall be pro-rated for the portion of the Performance Period that elapsed prior to this termination of employment and shall be paid at the time such amount would otherwise be payable as specified in Section 2. Disability shall be defined for purposes of this Agreement as a disability for a continuous period of at least six months under the Company’s long-term disability plan during the period of your continuous service as an employee of the Company.

7. Termination of Employment for Other Reasons. Except as otherwise provided in Sections 9 through 12, if your employment by the Company terminates during the Performance Period other than by reason of your death, disability, or retirement (as defined above), you will not be entitled to any payment pursuant to Section 2 with respect to the Performance Period.For the avoidance of doubt, your termination of employment will be deemed to occur on the date notice of termination is provided and will not be extended by any notice period that may be required contractually or under applicable law. Notwithstanding the foregoing, the Company’s Senior Vice President of Human Resources or the General Counsel shall have the sole discretion to determine the date of termination for purposes of participation in the Plan and the Performance Shares.

8. Detrimental Activity; Compensation Recovery Policy; Noncompetition and Nonsolicitiation Agreement. If you engage in detrimental activity (as defined in this Section 8) at any time (whether before or after termination of your employment), you will not be entitled to any payment hereunder and you will forfeit all rights with respect to the Performance Shares under this Agreement. For purposes of this Section 8, "detrimental activity" shall mean willful, reckless or grossly negligent activity that is determined by the Committee to be detrimental to or destructive of the business or property of the Company. Any such determination of the Committee shall be final and binding for all purposes. Notwithstanding the foregoing, no payment hereunder shall be forfeited or become not payable by virtue of this Section 8 on or after the date of a Change of Control (as defined in the Plan) unless the “Cause” standard set forth in Section 11(b) is satisfied. In addition, if you are or subsequently become an executive officer of the Company, a Senior Vice President, a Vice President & General Manager, a Vice President & Controller or another employee who becomes subject to the Policy (as defined below), your Performance Shares and the value you receive upon vesting of the Performance Shares will be subject to the Company’s Compensation Recovery Policy, as amended from time to time, including, without limitation, any amendments required to comply with the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Policy”), except where prohibited by law. Currently, the Company's executive officers, Senior Vice Presidents, Vice Presidents & General Managers and Vice Presidents & Controllers are the only employees subject to the Policy. If you become

3

subject to the Policy, you will be notified by the Company’s Human Resources department. Further, if you have attained the level of Vice President (or above) with the Company and you have not previously entered into a Noncompetition and Nonsolicitation Agreement with the Company (the “NCNS Agreement”), this grant of Performance Shares is contingent on your agreement, if requested by the Company within thirty days of the date of this Agreement, to be bound by the NCNS Agreement by returning a signed copy of the NCNS Agreement to the Company within the time period prescribed by the Company’s General Counsel.

9. Transfer of Employment; Leave of Absence. Except as otherwise required by Internal Revenue Code Section 409A, for the purposes of this Agreement, (a) a transfer of your employment from the Company to a subsidiary or vice versa, or from one subsidiary of the Company to another, without an intervening period, shall not be deemed a termination of employment, and (b) if you are granted in writing a leave of absence, you shall be deemed to have remained in the employ of the Company or a subsidiary of the Company during such leave of absence. If your level of employment changes, the Company may adjust your target payment hereunder to pro rate the portion of the Performance Period that elapses (i) prior to the change in employment status at the old target payment level and (ii) after the change at the new target payment level, if any. Any promotion to the ranks of “Designated Senior Executive” requires Committee action to adjust the target payment hereunder. If you are entitled to payment under this Agreement upon a termination of employment, Section 409A's definition of "separation of service," including its rules on leaves of absences, to the extent applicable, will be used to determine the date on which you actually terminate employment.

10. Adjustments. (a) In addition to the adjustments provided for in Section 3 of this Agreement, adjustments (which may be increases or decreases) may be made by the Committee in the Cumulative Sales and Return on Sales as well as in the TSR and list of peer companies,to take into account changes in law and accounting and tax rules and to make such adjustments as the Committee deems necessary or appropriate to reflect the inclusion or exclusion of the impact of extraordinary or unusual items, events or circumstances, including, without limitation, acquisitions or divestitures by or other material changes in the Company or peer companies, provided that no adjustment shall be made which would result in an increase in your compensation if your compensation is subject to the limitation on deductibility under Section 162(m) of the Internal Revenue Code, as amended, or any successor provision, for the year with respect to which the adjustment occurs.

(b) In the event of any change in or affecting the outstanding shares of Common Stock of the Company by reason of a stock dividend or split, merger or consolidation, or various other events, adjustments will be made as appropriate in connection with the Performance Shares as contemplated in the Plan.

(c) Subject to the provisions of Section 11, the determination of the Committee as to the terms of any adjustment made pursuant to this Section 10 shall be binding and conclusive upon you and any other person or persons who are at any time entitled to receipt of any payment pursuant to the award.

11. Change of Control. (a) Notwithstanding any other provision of this Agreement to the contrary, in the event that during the Performance Period your employment is terminated on or after a Change of Control (as defined in the Plan) (i) by the Company other than for Cause (as defined in Section 11(b)) or (ii) by you for Good Reason (as defined in Section 11(c)), your award shall become nonforfeitable and shall be paid out on the date of your “separation from service” within the meaning of Section 409A to the extent applicable, as if the Performance Period hereunder had been completed or satisfied and as if the Final Award Percentage for the Performance Period enabled a payment to you pursuant to Section 2 of the amount that is equal to your target performance shares for the Performance Period multiplied by the average actual percentage payout for the Company’s long-term incentive performance shares for the prior three completed performance periods.

(b)    For purposes of Sections 8 and 11(a), termination for "Cause" shall mean:

(i)your willful and continued failure to perform substantially your duties with the Company or one of its affiliates (other than any such failure resulting from incapacity due to physical or mental illness), after a written demand for substantial performance is delivered to you by (x) the Board or the Chief Executive Officer of the Company if you are an executive officer or Senior Vice President of the Company or (y) the Senior Vice President of Human Resources if you are not an executive officer or Senior Vice President of the Company. Such notice shall specifically identify the manner in which you have not substantially performed your duties, or

(ii)your willful engaging in illegal conduct or gross misconduct which is materially and demonstrably injurious to the Company.

For purposes of this provision, no act or failure to act, on the part of you, shall be considered "willful" unless it is done, or omitted to be done, by you in bad faith or without reasonable belief that your action or omission was in the best interests of the Company. If you are an executive officer or Senior Vice President of the Company, any act, or failure to act, based upon authority given pursuant to a resolution duly adopted by the Board or upon the instructions of the Chief Executive Officer or a

4

senior officer of the Company or based upon the advice of counsel for the Company shall be conclusively presumed to be done, or omitted to be done, by you in good faith and in the best interests of the Company. The cessation of an executive officer’s or Senior Vice President’s employment shall not be deemed to be for Cause unless and until there shall have been delivered to the executive officer or Senior Vice President a copy of the resolution duly adopted by the affirmative vote of not less than three-quarters of the entire membership of the Board at the meeting of the Board called and held for such purpose (after reasonable notice is provided and the executive officer or Senior Vice President is given an opportunity, together with counsel, to be heard before the Board), finding that, in the good faith opinion of the Board, the executive officer or Senior Vice President was guilty of the conduct described in subparagraph (i) or (ii) above, and specifying the particulars thereof in detail.

(c) For purposes of this Agreement, "Good Reason" shall mean:

(i)the assignment to you of any duties inconsistent in any material respect with your most significant position (including status, offices, titles and reporting requirements), authority, duties or responsibilities held, exercised and assigned at any time during the 120-day period immediately preceding the Change of Control, or any other action by the Company which results in a diminution in such position, authority, duties or responsibilities, excluding for this purpose an isolated, insubstantial and inadvertent action not taken in bad faith and which is remedied by the Company promptly after receipt of notice thereof given by you;

(ii)    requiring you to be based at any office or location other than the location where you were employed immediately preceding the Change of Control unless any office or location is less than 35 miles from such location, or if the distance from the new location to your residence is less than the distance from the old location to the residence;

(iii)any failure by the Company to maintain your compensation at a level consistent with that generally in effect prior to any Change of Control, other than an isolated, insubstantial and inadvertent failure not occurring in bad faith and which is remedied by the Company promptly after receipt of notice thereof given by you;

(iv)any purported termination by the Company of your employment otherwise than as expressly permitted by this Agreement; or

(v)any failure by the Company to comply with and satisfy Section 19(b) of this Agreement.

For purposes of this Section 11(c), any good faith determination of "Good Reason" made by you shall be conclusive.

(d)    Notwithstanding anything to the contrary in this Agreement (except to the extent that Section 11(a) provides for an earlier payment upon a termination of employment), if a Change of Control occurs during the Performance Period, the payment date for your Performance Shares will be deemed to be November of the last year of the Performance Period.

12. Divestiture. In the event that your principal employer is a subsidiary of the Company, it is possible that your principal employer may cease to be a subsidiary of the Company during the Performance Period and that your employment with the Company terminates as a result (the date of such cessation is herein called the Divestiture Date). If the divestiture of your principal employer constitutes a "change in control event" that meets the requirements of Section 409A, then your Performance Shares shall become nonforfeitable (to the extent not already nonforfeitable) and shall be paid out on the Divestiture Date as if the Performance Period hereunder had been completed or satisfied and as if the Final Award Percentage enabled a payment to you pursuant to Section 2 of the amount that is equal to your target performance sharesfor the Performance Period multiplied by the average actual percentage payout for the Company’s long-term incentive performance shares for the prior three completed performance periods. If the divestiture of your principal employer does not meet the requirements of a "change in control event" under Section 409A, then your Performance Shares shall become nonforfeitable (to the extent not already nonforfeitable) on the Divestiture Date and shall be paid out in November of the last year of the Performance Period consistent with the payout amount approved by the Compensation Committee for the Performance Period.

13. Accountant's Letter. As soon as practicable after the end of the Performance Period, the Committee shall obtain a letter or other communication from the Company’s Senior Vice President and Chief Financial Officer or the Vice President, Financeand Controller, or one of their successors or designees, to the effect that such person has reviewed the determination for the Performance Period of the Cumulative Sales, Return on Sales, TSR results and percentile ranking of the Company, as well as the Final Award Percentage, and that in such person’s opinion such determinations have been made in accordance with Section 3.

5

14. Employment Rights. The Performance Shares do not and are not intended to constitute or create a contract of employment. You shall not have any rights of employment or continued employment with the Company or any subsidiary as a result of the Performance Shares, other than the payment rights expressly contemplated herein.

15. Section 409A.

(a)    Notwithstanding any other provision of this Agreement to the contrary, the Company makes no representation that any amount payable under this Agreement will be exempt from or comply with Section 409A and makes no undertaking to preclude Section 409A from applying to such amount.

(b)    To the extent that any amount payable under this Agreement is paid upon a “separation from service” (within the meaning of Section 409A) to a “specified employee” (within the meaning of Section 409A), then such amount will not be paid during the six (6) month period following such separation from service, but will be paid within ten business days following such period.

16. Tax Withholding. As a condition of the grant and vesting of the Performance Shares, the Company, your employer or an administrative agent shall have the right, in whole in part, upon any payment to you of cash and/or Common Stock hereunder, (a) to deduct an amount equal to the taxes, social contributions, and/or other charges required to be withheld or otherwise applicable by law in respect of Performance Shares and Common Stock acquired or (b) to require you (or any other person entitled to the Performance Shares) to pay it an amount sufficient to provide for any such taxes, social charges and/or other charges. You agree that (for yourself and on behalf of any other person who becomes entitled to the Performance Shares or the Common Stock) that if the Company, your employer or an administrative agent elects to require you (or such other person) to remit an amount sufficient to pay such taxes, social contributions, and/or other charges, you (or such other person) must remit that amount within three business days after such amount is due. The Company will generally withhold required amounts from your payments, unless the Company has made other arrangements with you for you to promptly remit an amount sufficient to pay such withholding of tax, social contributions, and/or other charges (and may condition delivery of cash and/or Common Stock herunder upon such payment).  

You acknowledge and agree that you are solely responsible for any and all taxes, social contributions, and/or other charges that may be assessed by any taxing authority in the United States or any other jurisdiction arising from the Performance Shares, the Common Stock or dividends (if any), that such amounts may exceed the amount withheld by the Company, your employer or the administrative agent, and that neither the Company nor any affiliate is liable for any such assessments. You are solely responsible for all relevant documentation that may be required of you in relation to the Performance Shares, such as but not limited to personal income tax returns or reporting statements in relation to the receipt, holding, or subsequent sale of Common Stock and the receipt of dividends, if any. You acknowledge and agree that the Company makes no representations regarding the treatment of taxes, social contributions, or other charges and does not commit to and is under no obligation to structure the terms of the Plan or any award to reduce or eliminate your liability for any income taxes, social contributions, or other charges or to achieve any particular tax result. Furhter, if you become subject to tax in more than one jurisdiction, the Company, your employer, or an administrative agent may be required to withhold or account for such amounts in more than one jurisdiction. Consult a tax or financial advisor if you have questions.

17. Communications. The Company may, in its sole discretion, decide to deliver any documents related to the Performance Shares, future Performance Shares, the Common Stock, or any other Company-related documents by electronic means. By accepting the Performance Shares, whether electronically or otherwise, you hereby consent to receive such documents by electronic delivery and agree to participate in the Plan through an on-line or electronic system established and maintained by the Company or another third party designated by the Company, including, but not limited to the use of electronic signatures or click-through electronic acceptance of terms and conditions.If you have been provided with a copy of this Agreement, the Plan, or any other relevant documentation in a language other than English, unless otherwise required by applicable law, the English language documents will prevail in case of any ambiguities or divergences as a result of translation.

18. Governing Law and Forum; Severability. This Agreement and the Company’s obligation to issue Common Stock in respect of the Performance Shares shall be governed by and construed in accordance with the laws ofthe State ofDelaware, without regard to the conflict of law principles thereof. If one or more of the provisions herein shall be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby and the invalid, illegal or unenforceable provisions shall be deemed null and void; however, to the extent permissible by law, any provisions that could be deemed null and void shall first be construed, interpreted or revised retroactively to permit this Agreement to be construed so as to foster the intent of this Agreement and the Plan. For purposes of resolving any dispute that may arise directly or indirectly from this Agreement, the parties hereby agree that any such dispute that cannot be resolved by the parties shall be submitted to the exclusive jurisdiction of state and federal courts located in the state of Delaware.

19. Successors. (a) This Agreement shall inure to the benefit of and be binding upon the Company and its successors and assigns.

(b) The Company will require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company to assume expressly and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place. As used in this Agreement, "Company" shall mean the Company as hereinbefore defined and any successor to its business and/or assets as aforesaid which assumes and agrees to perform this Agreement by operation of law, or otherwise.

20. Administration. Consistent with Section 8 of the Plan, the Committee shall interpret and administer the Plan, this Agreement and the Performance Shares. The actions and determinations of the Committee on all matters relating to the Plan, this Agreement and the Performance Shares will be final and conclusive.

[1] During the three months ended December 31, 2014, and December 31, 2013, the Company incurred $0 million and $3 million, respectively, of bridge credit facility fees related to the acquisition of ARINC. These costs are included in interest expense; therefore total transaction costs related to the acquisition of ARINC during these periods were $0 million and $15 million, respectively.

[2] Option-holders of ARINC were due approximately $61 million at the transaction closing date. This payment did not clear until December 24, 2013. Therefore the opening balance sheet, which was prepared as of December 23, 2013, includes restricted cash of $61 million and a current liability payable to the ARINC option holders for an equal amount.

[3] On March 28, 2014, the Company sold the building which was classified as held for sale at the acquisition date. For more information related to the Building held for sale, see discussion below.

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, 2014, 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. The Company has recorded environmental reserves for this site of $6 million as of December 31, 2014, 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.

Acquisitions

On December 23, 2013, the Company acquired 100 percent of the outstanding common stock and voting interests of Radio Holdings, Inc. (Radio Holdings), the holding company of ARINC, a leading global provider of air-to-ground data and voice communication services. ARINC develops and operates communications and information processing systems and provides systems engineering and integration solutions to five key industries: commercial aviation, business aviation, airports, rail and nuclear security. Combining ARINC's communication networks and services with the Company's onboard aircraft information systems strengthens the Company's ability to deliver enhanced connectivity to aircraft operators worldwide.

The ARINC purchase price was $1,405 million, net of cash acquired and net of $10 million in cash received by the Company in June 2014 from the settlement of various post-closing matters, including adjustments for changes in working capital. As discussed in Note 10, the Company used proceeds from the issuance of long-term debt and commercial paper to finance the cash purchase price. The following table summarizes the fair value of assets acquired and liabilities assumed at the acquisition date.

(in millions)	December 23, 2013

Net Assets Acquired	$	1,405

⁽¹⁾ Option-holders of ARINC were due approximately $61 million at the transaction closing date. This payment did not clear until December 24, 2013. Therefore the opening balance sheet, which was prepared as of December 23, 2013, includes restricted cash of $61 million and a current liability payable to the ARINC option holders for an equal amount.

⁽²⁾ On March 28, 2014, the Company sold the building which was classified as held for sale at the acquisition date. For more information related to the Building held for sale, see discussion below.

⁽³⁾ Assets and liabilities associated with the Business held for sale relate to ASES, which the Company intends to divest, as detailed in Note 4.

The final determination of the fair value of certain assets and liabilities was completed during the first quarter of 2015, within the one year measurement period as allowed by FASB Accounting Standards Codification Topic 805, Business Combinations (ASC 805). As of December 31, 2014, the valuation studies necessary to determine the fair market value of the assets acquired and liabilities assumed were complete.

The purchase price allocation resulted in the recognition of $1,087 million of goodwill, none of which is expected to be deductible for tax purposes. All of the goodwill is included in the Company’s Information Management Services segment. The goodwill is primarily a result of revenue synergy opportunities generated by the combination of the Company’s aviation electronics and flight services business with ARINC’s network communication solutions and cost synergies resulting from the consolidation of certain corporate and administrative functions. Goodwill also results from the workforce acquired with the business. See Note 22 for additional information relating to the Information Management Services segment.

ARINC’s results of operations have been included in the Company's operating results for the period subsequent to the completion of the acquisition on December 23, 2013. For the three months ending December 31, 2014 and 2013, ARINC contributed sales of $137 million and $6 million, respectively and net income of $12 million and $1 million, respectively.

Building Held For Sale and Liability Related to Building Held for Sale

In connection with the acquisition of ARINC, the Company classified $81 million of acquired real estate assets as Building held for sale at the acquisition date, as well as an $81 million liability related to the Building held for sale at the acquisition date. The assets and related liability were recorded at their estimated fair value.

In November 2004, ARINC obtained approval from the Department of Labor to contribute these real estate assets to its defined benefit pension plan. In connection with this transaction, ARINC entered into a simultaneous agreement to leaseback the contributed facilities for a period of twenty years, through November 1, 2024. As a result of the related party elements of the transaction, no sale or gain was recognized when ARINC contributed the real estate to its pension plan. Instead, ARINC recognized a deferred gain liability equal to the fair value of the contributed real estate. The increase in deferred gain liability was offset by an equal reduction to pension plan liabilities to recognize the fair value of the contributed real estate in the funded status of the pension plan.

The Building held for sale was comprised of the land and buildings of the ARINC corporate headquarters located in Annapolis, Maryland. The related liability represented future rental payment obligations under the leaseback agreement. As of the acquisition date, the real estate assets were being marketed for sale. In March 2014, the assets were sold to an unrelated third party. The net proceeds from the sale of $81 million were remitted directly to the ARINC pension plan, and have been included as a benefit to the funded status of that plan. The sale had no impact on the Company's Condensed Consolidated Statement of Operations or Condensed Consolidated Statement of Cash Flows.

Concurrent with the sale of the real estate assets, the Company entered into revised lease agreements with the new owner of the Annapolis, Maryland facilities, extending the lease term for a portion of the facility through March 31, 2029. A portion of the leased assets have been classified as a capital lease resulting in the establishment of capital lease assets and offsetting capital lease obligation on the Company's Condensed Consolidated Statement of Financial Position.

Supplemental Pro-Forma Data

The following unaudited supplemental pro-forma data presents consolidated pro-forma information as if the acquisition and related financing had been completed as of the beginning of the prior year, or on October 1, 2013.

The unaudited supplemental pro-forma financial information does not reflect the potential realization of revenue synergies or cost savings, nor does it reflect other costs relating to the integration of the two companies. This pro-forma data should not be considered indicative of the results that would have actually occurred if the acquisition and related financing been consummated on October 1, 2013, nor are they indicative of future results.

The unaudited supplemental pro-forma financial information was calculated by combining the Company's results with the stand-alone results of ARINC for the pre-acquisition period, which were adjusted to account for certain transactions and other costs that would have been incurred during this pre-acquisition period.

	Three Months Ended December 31
(in millions, except per share amounts)	2014		2013
Pro-forma sales	$	1,226	$	1,160
Pro-forma net income attributable to common shareowners from continuing operations	$	169	$	139
Pro-forma basic earnings per share from continuing operations	$	1.28	$	1.03
Pro-forma diluted earnings per share from continuing operations	$	1.26	$	1.02

The unaudited supplemental pro-forma data above exclude the results of ASES, which the Company intends to divest, as detailed in Note 4. The following significant adjustments were made to account for certain transactions and costs that would have occurred if the acquisition had been completed on October 1, 2013. These adjustments are net of any applicable tax impact and were included to arrive at the pro-forma results above. As the acquisition of ARINC was completed on December 23, 2013, the pro forma adjustments for the three months ended December 31, 2013 in the table below include only the required adjustments through December 23, 2013.

	Three Months Ended December 31

Net reduction to depreciation resulting from fixed asset purchase accounting adjustments(1)	$	—	$	2
Advisory, legal and accounting service fees(2)	—		20
Amortization of acquired ARINC intangible assets, net(3)	—		(4		)

⁽¹⁾ This adjustment captures the net impact to depreciation expense resulting from various purchase accounting adjustments to fixed assets

⁽²⁾ This adjustment reflects the elimination of transaction-related fees incurred by ARINC and Rockwell Collins in connection with the acquisition and assumes all of the fees were incurred during the first quarter of 2013

⁽³⁾ This adjustment eliminates amortization of the historical ARINC intangible assets and replaces it with the new amortization for the acquired intangible assets

Significant Accounting Policies (Policies)

Accounting Policies [Abstract]

Recently Adopted and Issued Accounting Standards

In April 2014 the Financial Accounting Standards Board (FASB) issued guidance that modifies the criteria used to qualify divestitures for classification as discontinued operations and expands disclosures related to disposals of significant components. The amendment will become effective for the company in fiscal 2016 with early adoption permitted; the Company does not currently expect to early adopt the amended guidance. The amended guidance is expected to decrease the likelihood that future disposals will qualify for discontinued operations treatment, meaning that the results of operations of some future disposals may be reported in continuing operations.

In May 2014 the FASB issued a comprehensive new revenue recognition standard that effectively replaces all current guidance on the topic and expands disclosures regarding revenue. The guidance permits the use of either a retrospective or cumulative effect transition method. The new standard is effective for the Company in fiscal 2018 and early adoption is not permitted. The Company is currently evaluating the transition methods allowed under the new standard and the effect the standard will have on our consolidated financial statements and related disclosures. Given the new standard's impact on business processes, systems and internal controls, analysis of the new guidance will likely extend over several future periods.

⁽¹⁾ During the three months ended December 31, 2014, and December 31, 2013, the Company incurred $0 million and $3 million, respectively, of bridge credit facility fees related to the acquisition of ARINC. These costs are included in interest expense; therefore total transaction costs related to the acquisition of ARINC during these periods were $0 million and $15 million, respectively.

The Company evaluates performance and allocates resources based upon, among other considerations, segment operating earnings. The Company's definition of segment operating earnings excludes income taxes, stock-based compensation, unallocated general corporate expenses, interest expense, gains and losses from the disposition of businesses, restructuring and asset impairment charges, and other special items as identified by management from time to time. Intersegment sales are not material and have been eliminated.

The following table summarizes sales by category for the three months ended December 31, 2014 and 2013:

	Three Months Ended December 31

Total sales	$	1,226	$	1,054

The air transport and business and regional aviation electronics sales categories are delineated based on the difference in underlying customer base, size of aircraft and markets served. For the three months ended December 31, 2014 and 2013, sales for air transport aviation electronics include revenue from wide-body in-flight entertainment products and services of $16 million and $19 million, respectively.

Sales categories for Government Systems are delineated based upon differences in the underlying product and service technologies and markets served. Prior period results of the Communication products category in Government Systems have been revised to exclude the divested Datapath business, which is now reported as a discontinued operation, as discussed in Note 4, Discontinued Operations and Divestitures.

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 systems for commercial and military customers and provides information management services through voice and data communication networks and solutions 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 dates.

The Company has one consolidated subsidiary with income attributable to 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, 2014.

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, 2014 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 first quarter of 2014, the Company acquired ARINC Incorporated (ARINC). As a result of the acquisition, the Company’s service sales are greater than ten percent of total sales. Accordingly, service and product sales and service and product cost of sales are presented separately and prior period results were reclassified to conform to the current year presentation. 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.

As discussed in Note 4, Discontinued Operations and Divestitures, on July 25, 2014 the Company divested its satellite communication systems business, formerly known as Datapath, Inc. (Datapath), with operations in Duluth, Georgia and Stockholm, Sweden. As a result, this business has been accounted for as discontinued operations for all periods presented. The Company also intends to divest ARINC's Aerospace Systems Engineering and Support (ASES) business, which provides military aircraft integration and modifications, maintenance, and logistics and support, in order to align with the Company's long-term primary business strategies. During the fourth quarter of 2014, the Company entered into an agreement to divest this business. Subsequently, during the quarter ended December 31, 2014, the parties mutually agreed to terminate the agreement and ASES remains classified as held-for-sale. The operating results of ASES are included in discontinued operations in the Company's Condensed Consolidated Statement of Operations for all periods presented.

Fair Value Measurements

Fair Value Disclosures [Abstract]

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, 2014 and September 30, 2014 are as follows:

		December 31, 2014			September 30, 2014
(in millions)	Fair Value Hierarchy	Fair Value Asset (Liability)			Fair Value Asset (Liability)
Deferred compensation plan investments	Level 1	$	53		$	50
Interest rate swap assets	Level 2	24			18
Foreign currency forward exchange contract assets	Level 2	6			6
Foreign currency forward exchange contract liabilities	Level 2	(13		)	(9		)

There were no transfers between Levels of the fair value hierarchy during the three months ended December 31, 2014 or 2013.

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

	Asset (Liability)
	December 31, 2014						September 30, 2014
(in millions)	Carrying Amount			Fair Value			Carrying Amount			Fair Value
Cash and cash equivalents	$	315		$	315		$	323		$	323
Short-term debt	(831		)	(831		)	(504		)	(504		)
Long-term debt	(1,646		)	(1,788		)	(1,645		)	(1,747		)

The fair value of cash and cash equivalents and short-term debt approximates their carrying value due to the short-term nature of the instruments. These items are within Level 1 of the fair value hierarchy. Fair value information for all long-term debt is within Level 2 of the fair value hierarchy. The fair value of these financial instruments was 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.

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:

(in millions)	2014			2013

Changes in estimates for prior years	—			(6		)
Foreign currency translation adjustments and other	(1		)	—
Balance at December 31	$	103		$	116

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, 2014, the outstanding loan balance was approximately $3 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, 2014, 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, 2014 were $280 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:

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.

Pension Plan Funding

The Company’s objective with respect to the funding of its pension plans is to provide adequate assets for the payment of future benefits. Pursuant to this objective, the Company will fund its pension plans as required by governmental regulations and may consider discretionary contributions as conditions warrant. In October 2014, the Company voluntarily contributed $55 million to its U.S. qualified pension plan. There was no minimum statutory funding requirement for 2015 and the Company does not currently expect to make any additional discretionary contributions during 2015 to this plan. Furthermore, the Company is not required to make, and does not intend to make, any contributions to the ARINC pension plans during 2015. Any additional future contributions necessary to satisfy minimum statutory funding requirements are dependent upon actual plan asset returns, interest rates, and actuarial assumptions. Contributions to the non-U.S. plans and the U.S. non-qualified plan are expected to total $14 million in 2015.

ARINC Pension Plan and Other Retirement Benefits

ARINC sponsors two primary pension sub-plans: one for union employees and one for non-union employees. ARINC also provides postretirement health coverage for many of its current and former employees and postretirement

life insurance benefits for certain retirees. The ARINC pension and postretirement benefit obligations are included within Retirement Benefits as liabilities on the Company's Condensed Consolidated Statement of Financial Position as of December 31, 2014.

Inventories, net	$	1,779		$	1,709

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 under long-term supply arrangements with the Company's customers. Pre-production engineering costs incurred pursuant to supply arrangements that do not contain contractual guarantees for reimbursement are expensed as incurred.

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

Anticipated amortization expense for pre-production engineering costs	$	48	$	77	$	93	$	104	$	104	$	493

Amortization expense for pre-production engineering costs for the three months ended December 31, 2014 and 2013 was $12 million and $6 million, respectively. As of December 31, 2014, the weighted average amortization period remaining for pre-production engineering costs included in Inventories, net was approximately 11 years.

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 a 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 March, 2014 the Company entered into three interest rate swap contracts (the 2023 Swaps) which expire on December 15, 2023 and effectively converted $200 million of the 2023 Notes to floating rate debt based on one-month LIBOR plus 0.94 percent.

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.

The Company designated the 2019 and 2023 Swaps (the Swaps) as fair value hedges. The 2019 and 2023 Swaps are recorded within Other Assets at a fair value of $24 million, offset by a fair value adjustment to Long-term Debt (Note 10) of $24 million at December 31, 2014. At September 30, 2014, the Swaps were recorded within Other Assets at a fair value of $18 million, offset by a fair value adjustment to Long-term Debt (Note 10) of $18 million. Cash payments or receipts between the Company and the counterparties to the Swaps are recorded as an adjustment to interest expense.

Forward Starting Interest Rate Swaps

In September 2013, the Company entered into forward starting interest rate swap agreements with combined notional values of $200 million to effectively lock in fixed interest rates on a portion of the long-term debt it incurred in December 2013 to refinance maturing debt and to fund the acquisition of ARINC. In October 2013, the Company entered into an additional $300 million notional value of forward starting interest rate swap agreements. These forward starting interest rate swaps were designated as cash flow hedges and were executed to hedge the risk of potentially higher benchmark U.S. Treasury bond yields on long-term debt with maturities ranging from 2023 to 2043 and fixed interest rates ranging between 2.8150 percent and 3.8775 percent. The forward starting interest rate swaps were terminated in December 2013 concurrent with the Company's debt issuance. Upon termination, the forward starting swaps were valued at a net loss of $2 million. This net loss has been deferred within Accumulated other comprehensive losses in the Condensed Consolidated Statement of Financial Position and will be amortized into interest expense over the life of the corresponding debt.

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, 2014 and September 30, 2014, the Company had outstanding foreign currency forward exchange contracts with notional amounts of $329 million and $575 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, 2014 and September 30, 2014 are as follows:

		Asset Derivatives

		Liability Derivatives
(in millions)	Classification	December 31, 2014		September 30, 2014
Foreign currency forward exchange contracts	Other current liabilities	$	13	$	9

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, 2014 there were undesignated foreign currency forward exchange contracts classified within other current assets of $0 million and other current liabilities of $1 million.

The effect of derivative instruments on the Condensed Consolidated Statement of Operations for the three months ended December 31, 2014 and 2013 is as follows:

		Amount of Gain (Loss)

There was no significant impact to the Company’s earnings related to the ineffective portion of any hedging instruments during the three months ended December 31, 2014. 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, 2014.

The Company did not have any hedges with credit-risk-related contingent features or that required the posting of collateral as of December 31, 2014. The cash flows from derivative contracts are recorded in operating activities in the Condensed Consolidated Statement of Cash Flows.

Cash flow hedges are de-designated 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 $6 million of net losses into earnings over the next 12 months. The maximum duration of a foreign currency cash flow hedge contract at December 31, 2014 was 67 months.

Investments in Equity Affiliates

Investments in equity affiliates primarily consist of seven joint ventures, which are accounted for under the equity method. Under the equity method of accounting for investments, the Company's proportionate share of 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.

All of the Company's joint ventures are 50 percent owned.

As a result of the ARINC acquisition, the Company has allocated $384 million to finite-lived intangible assets with a weighted average life of approximately 15 years and $47 million to indefinite-lived intangible assets.

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, 2014, the weighted average amortization period remaining for up-front sales incentives was approximately 11 years.

Anticipated annual amortization expense for intangible assets is as follows:

(in millions)	2015		2016		2017		2018		2019		Thereafter

Amortization expense for intangible assets for the three months ended December 31, 2014 and 2013 was $12 million and $6 million respectively.

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

Commercial Paper Program

Under the Company’s commercial paper program, the Company may sell up to $1 billion 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. The commercial paper program is supported by the Company's $1 billion five-year revolving credit facility. At December 31, 2014, short-term commercial paper borrowings outstanding were $831 million with a weighted-average interest rate and maturity period of 0.42 percent and 22 days, respectively. At September 30, 2014, short term commercial paper borrowings outstanding were $504 million with a weighted-average interest rate and maturity period of 0.32 percent and 29 days, respectively.

Revolving Credit Facilities

On September 24, 2013, the Company entered into new credit agreements to ensure adequate commercial paper borrowing capacity in anticipation of the Company's then pending ARINC acquisition and to meet other short-term cash requirements. The Company closed on these new revolving credit facilities on December 23, 2013, concurrent with the ARINC acquisition closing date. These new credit facilities consist of a five-year $1 billion credit facility that expires in December 2018 and a 364-day $200 million credit facility that expired in December 2014 and was not renewed. These agreements replaced the prior $850 million revolving credit facility that was terminated concurrently upon the closing of the new agreements.

The credit facilities include 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 equity impact on accumulated other comprehensive loss related to defined benefit retirement plans. The ratio was 44 percent as of December 31, 2014. The credit facilities also contain 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 these credit facilities 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, 2014 and September 30, 2014 there were no outstanding borrowings under these revolving credit facilities.

In addition, short-term credit facilities available to non-U.S. subsidiaries amounted to $41 million as of December 31, 2014, of which $12 million was utilized to support commitments in the form of commercial letters of credit. At

December 31, 2014 and September 30, 2014, there were no short-term borrowings outstanding under the Company’s non-U.S. subsidiaries’ credit facilities.

At December 31, 2014 and September 30, 2014, there were no significant commitment fees or compensating balance requirements under any of the Company’s credit facilities.

December 2013 Long-term Debt Issuances

On December 16, 2013, the Company issued $300 million of floating rate unsecured debt due December 15, 2016 (the 2016 Notes). The 2016 Notes bear annual interest at a rate equal to three-month LIBOR plus 0.35 percent. As of December 31, 2014 the quarterly interest rate was 0.59 percent. The rate resets quarterly. The net proceeds to the Company from the 2016 Notes, after deducting $1 million of debt issuance costs, were $299 million.

On December 16, 2013, the Company issued $400 million of 3.7 percent fixed rate unsecured debt due December 15, 2023 (the 2023 Notes). The net proceeds to the Company from the 2023 Notes, after deducting a $1 million discount and $3 million of debt issuance costs, were $396 million. In March 2014, the Company entered into interest rate swap contracts which effectively converted $200 million of the 2023 Notes to floating rate debt based on one-month LIBOR plus 0.94 percent. See Notes 16 and 17 for additional information relating to the interest rate swap contracts.

On December 16, 2013, the Company issued $400 million of 4.8 percent fixed rate unsecured debt due December 15, 2043 (the 2043 Notes). The net proceeds to the Company from the 2043 Notes, after deducting a $2 million discount and $4 million of debt issuance costs, were $394 million.

The net proceeds after discounts and debt issuance costs from the December 16, 2013 debt issuances totaled $1,089 million. Approximately $900 million was used to finance the ARINC acquisition and approximately $200 million was used to refinance the 2013 Notes that matured on December 1, 2013. The remaining ARINC purchase price was funded using commercial paper proceeds.

Other 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).

In January 2010, the Company entered into interest rate swap contracts which effectively converted $150 million of the 2019 Notes to floating rate debt based on six-month LIBOR plus 1.235 percent. See Notes 16 and 17 for additional information relating to the interest rate swap contracts.

The 2043, 2023, 2021, 2019 and 2016 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 are recorded in Interest expense.

The 2043, 2023, 2021, 2019 and 2016 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, 2014 and September 30, 2014.

Income Tax Disclosure [Abstract]

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, 2014 and 2013, the effective income tax rate from continuing operations was 22.5 percent and 27.2 percent, respectively. The lower current year effective income tax rate from continuing operations was primarily due to the retroactive extension of the Federal R&D Tax Credit which had previously expired on December 31, 2013, partially offset by the absence of the recognition of a tax benefit related to prior years' Extraterritorial Income Exclusion deductions. On December 19, 2014, the Tax Increase Prevention Act of 2014 was enacted, which retroactively reinstated and extended the Federal R&D Tax Credit from January 1, 2014 through December 31, 2014.

The Company's U.S. Federal income tax returns for the tax year ended September 30, 2011 and prior years have been audited by the IRS and are closed to further adjustments by the IRS. The IRS is currently auditing the Company's tax returns for the years ended September 30, 2012 and 2013. ARINC's U.S. Federal income tax returns are currently under audit by the IRS for the tax years ended December 31, 2009 and December 31, 2012 and are closed to further adjustments by the IRS for all tax years ended December 31, 2008 and prior. The Company and ARINC are also currently under audit in various U.S. states and non-U.S. jurisdictions. The U.S. states and non-U.S. jurisdictions have statutes of limitations generally ranging from 3 to 5 years. The Company believes it has adequately provided for any tax adjustments that may result from the various audits.

The Company had net income tax payments of $23 million and $49 million during the three months ended December 31, 2014 and 2013, respectively.

The Company has gross unrecognized tax benefits recorded within Other Liabilities in the Condensed Consolidated Statement of Financial Position of $55 million and $48 million as of December 31, 2014 and September 30, 2014, respectively. The total amount of unrecognized tax benefits that, if recognized, would affect the effective income tax rate was $31 million and $25 million as of December 31, 2014 and September 30, 2014, 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 in the range of $0 to $1 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 $2 million and $1 million as of December 31, 2014 and September 30, 2014, respectively. The total amount of interest and penalties recorded as an expense or (income) within Income tax expense in the Condensed Consolidated Statement of Operations was $0 million for each of the three months ended December 31, 2014 and 2013, respectively.

Discontinued Operations and Divestitures

Discontinued Operations and Divestitures

On July 25, 2014, the Company sold its satellite communication systems business formerly known as Datapath, Inc. (Datapath). The sales price, which is subject to post-closing adjustments for changes in working capital and other items, was $10 million. The Company recognized a pre-tax loss of $12 million ($2 million after-tax) related to the divestiture of the Datapath business. The high effective tax rate is primarily attributable to differences in the treatment of goodwill for income tax and financial reporting purposes. The operating results of Datapath, including the loss realized on the disposition, have been included in discontinued operations in the Company's Condensed Consolidated Statement of Operations for all periods presented. The Datapath business was formerly included in the Government Systems segment. The divestiture of this business is part of our strategy to reshape the Government Systems segment to align with the changing dynamics of the defense environment and focus on opportunities in addressed markets for the Company's core products and solutions.

The Company also intends to divest ARINC's ASES business, which provides military aircraft integration and modifications, maintenance, and logistics and support, in order to align with the Company's long-term primary business strategies. During the fourth quarter of 2014, the Company entered into an agreement to divest this business. Subsequently, during the quarter ended December 31, 2014, the parties mutually agreed to terminate the agreement and ASES remains classified as held-for-sale. The operating results of ASES are included in discontinued operations in the Company's Condensed Consolidated Statement of Operations for all periods presented.

As of December 31, 2014, the Company has classified $17 million of assets related to ASES as a business held-for-sale within current assets and $12 million of liabilities related to ASES as a business held-for-sale within current liabilities on the Condensed Consolidated Statement of Financial Position. The held-for-sale assets are primarily comprised of Receivables, and the held-for-sale liabilities are primarily comprised of Accounts payable and Other current liabilities.

Results of discontinued operations are as follows:

	Three Months Ended December 31
(in millions)	2014			2013
Sales	$	8		$	17
(Loss) from discontinued operations before income taxes	(3		)	(4		)
Income tax benefit from discontinued operations	1			1

On November 22, 2013, the Company sold its subsidiary, Kaiser Optical Systems, Inc. (KOSI), a supplier of spectrographic instrumentation and applied holographic technology, to Endress+Hauser. The sale price, after post-closing adjustments for changes in working capital, was $23 million. This resulted in a pretax gain of $10 million, which was included in Other income, net during the three months ended December 31, 2013. The divestiture of this business is part of our strategy to reshape the Government Systems segment to align with the changing dynamics of the defense environment and focus on opportunities in addressed markets for the Company's core products and solutions. As part of the divestiture agreement, the Company entered into a long-term supply agreement with the buyer that allows the Company to continue purchasing certain products from KOSI after completion of the sale. As a result of this continuing involvement, the KOSI divestiture did not qualify for classification as a discontinued operation.

Restructuring, Pension Settlement and Asset Impairment Charges, Net

In September 2014, the Company recorded pension settlement and restructuring charges totaling $9 million. This amount was comprised of (i) $5 million for pension settlement charges (included within Selling, general, and administrative expense) and (ii) $4 million for employee severance costs related to the consolidation and closure of two service centers as part of a plan to optimize the efficiency of the Company's global service center footprint. These severance costs were included within cost of sales. Through December 31, 2014, the Company has made cash payments of $7 million associated with these actions. As of December 31, 2014, approximately $2 million of employee severance costs remain to be paid in future periods.

During the year ended September 30, 2012, the Company recorded 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 the workforce in anticipation of the sequestration impacts on the U.S. defense budgets. Through December 31, 2014, the Company has made cash severance payments of approximately $31 million related to the 2012 restructuring action. As of December 31, 2014, $4 million of employee separation costs related to the 2012 action remains to be paid in future periods.

Pension Plan Funding

The Company’s objective with respect to the funding of its pension plans is to provide adequate assets for the payment of future benefits. Pursuant to this objective, the Company will fund its pension plans as required by governmental regulations and may consider discretionary contributions as conditions warrant. In October 2014, the Company voluntarily contributed $55 million to its U.S. qualified pension plan. There was no minimum statutory funding requirement for 2015 and the Company does not currently expect to make any additional discretionary contributions during 2015 to this plan. Furthermore, the Company is not required to make, and does not intend to make, any contributions to the ARINC pension plans during 2015. Any additional future contributions necessary to satisfy minimum statutory funding requirements are dependent upon actual plan asset returns, interest rates, and actuarial assumptions. Contributions to the non-U.S. plans and the U.S. non-qualified plan are expected to total $14 million in 2015.

ARINC Pension Plan and Other Retirement Benefits

ARINC sponsors two primary pension sub-plans: one for union employees and one for non-union employees. ARINC also provides postretirement health coverage for many of its current and former employees and postretirement

life insurance benefits for certain retirees. The ARINC pension and postretirement benefit obligations are included within Retirement Benefits as liabilities on the Company's Condensed Consolidated Statement of Financial Position as of December 31, 2014.
