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, June 30 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 and nine months ended June 30, 2015 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.

As discussed in Note 4, Discontinued Operations and Divestitures, on March 10, 2015, the Company divested ARINC's Aerospace Systems Engineering and Support (ASES) business, which provides military aircraft integration and modifications, maintenance and logistics and support. On July 25, 2014, the Company divested its satellite communication systems business, formerly known as Datapath, Inc. (Datapath). As a result, the Datapath and ASES businesses have been accounted for as discontinued operations for all periods presented.

2. Recently Issued Accounting Standards

In May 2014, the Financial Accounting Standards Board (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 use of either a retrospective or cumulative effect transition method. Based upon the FASB's recent decision to approve a one year delay in implementation, the new standard is now effective for the Company in fiscal 2019, with early adoption permitted, but not earlier than fiscal 2018. The Company is currently evaluating the transition methods allowed under the new standard and the effect the standard will have on the Company's 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.

In April 2014, the 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.

3.Acquisitions

On March 20, 2015, the Company acquired 100 percent of the outstanding shares of Pacific Avionics Pty. Limited (Pacific Avionics), a Singapore-based company specializing in technologies used for wireless information distribution, including in-flight entertainment and connectivity. The purchase price, net of cash acquired, was $24 million. The Company is in the process of allocating the purchase price and obtaining a valuation for acquired intangible assets and their useful lives. Based on the Company's preliminary allocation of the purchase price, $9 million has been allocated to in process research and development (IPR&D) and $15 million to goodwill, none of which is deductible for tax purposes. The acquired IPR&D is recorded at fair value as an indefinite-lived intangible asset until the development is complete, at which time the asset will be considered a finite-lived intangible asset and amortized over its estimated useful life. The excess purchase price over net assets acquired, including intangible assets, reflects the Company's view that this acquisition will further enhance the Company's cabin products and information management services portfolios. Pacific Avionics is included within the Commercial Systems segment, and its results of operations have been included in the Company's operating results for the period subsequent to the completion of the acquisition on March 20, 2015. Pro-forma results of operations have not been presented because the effect of the acquisition is not material to the Company's consolidated results of operations.

On December 23, 2013, the Company acquired 100 percent of the outstanding common stock and voting interests of Radio Holdings, Inc., 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 billion, 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

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 divested, as detailed in Note 4.

The purchase price allocation resulted in the recognition of $1.087 billion of goodwill and $431 million of intangible assets with a weighted average useful life of approximately 15 years. None of the goodwill 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 ended June 30, 2015 and 2014, ARINC contributed sales of $140 million and $134 million, respectively, and net income of $21 million and $12 million, respectively. For the nine months ended June 30, 2015 and 2014, ARINC contributed sales of $421 million and $277 million, respectively, and net income of $47 million and $22 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

ROCKWELL COLLINS, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(Unaudited)

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 of $81 million from the sale 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 prior to 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 had been consummated prior to 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.

The unaudited supplemental pro-forma data above excludes the results of ASES, which the Company divested, 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 prior to October 1, 2013. These adjustments are net of any applicable tax impact and were included to arrive at the pro-forma results above.

⁽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 March 10, 2015, the Company sold 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. The sale pricewas $3 million, and additional post-closing consideration of up to $4 million may be received. The Company recognized a pre-tax loss of $5 million ($3 million after-tax) related to the ASES divestiture. The operating results of ASES, including the loss realized on the disposition, have been included within discontinued operations in the Company's Condensed Consolidated Statement of Operations for all periods presented.

On July 25, 2014, the Company sold its satellite communication systems business formerly known as Datapath. The sale 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 the Company's 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.

Results of discontinued operations are as follows:

	Three Months Ended					Nine Months Ended
	June 30					June 30
(in millions)	2015		2014			2015			2014

Loss from discontinued operations before income taxes	—		(13		)	(13		)	(17		)
Income tax benefit from discontinued operations	—		8			5			9

During the first quarter of 2014, 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. The divestiture of this business is part of the Company's 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.

Pre-production engineering costs	975			876
Inventories, net	$	1,844		$	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:

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 June 30, 2015, the weighted average amortization period remaining for up-front sales incentives was approximately 10 years.

Anticipated annual amortization expense for intangible assets is as follows:

Investments in Equity Affiliates

Investments in equity affiliates primarily consist of eight 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.

During the second quarter of 2015, the Company established a new joint venture, ACCEL (Tianjin) Flight Simulation Co., Ltd (ACCEL), to develop and deliver commercial flight simulators in China. ACCEL is a 50 percent owned joint venture with Beijing Bluesky Aviation Technology, an AVIC subsidiary. The Company's share of earnings or losses of ACCEL are included in the operating results of the Commercial Systems Segment. Consistent with the terms of the joint venture agreement, the Company expects to contribute cash totaling $7 million to the joint venture later in fiscal 2015 and fiscal 2016.

The Company's remaining joint ventures are also 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. The results of Rockwell Collins CETC Avionics Co., Ltd (RCCAC) and AVIC Leihua Rockwell Collins Avionics Company (ALRAC) are included in the operating results of the Commercial Systems segment, and ADARI Aviation Technology Limited (ADARI) is included in the operating results of the Information Management Services segment.

In the normal course of business or pursuant to the underlying joint venture agreements, the Company may sell products or services to equity affiliates. The Company defers a portion of the profit generated from these sales equal to its ownership interest in the equity affiliates until the underlying product is ultimately sold to an unrelated third party. Sales to equity affiliates were $51 million and $139 million for the three and nine months ended June 30, 2015, respectively, and $42 million and $118 million for the three and nine months ended June 30, 2014, respectively. The deferred portion of profit generated from sales to equity affiliates was $1 million at June 30, 2015 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 $7 million for the three and nine months ended June 30, 2015, respectively, and $3 million and $8 million for the three and nine months ended June 30, 2014, 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 June 30, 2015, short-term commercial paper borrowings outstanding were $745 million with a weighted-average interest rate and maturity period of 0.51 percent and 28 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 42 percent as of June 30, 2015. 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 June 30, 2015 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 $39 million as of June 30, 2015, of which $11 million was utilized to support commitments in the form of commercial letters of credit. At

June 30, 2015 and September 30, 2014, there were no short-term borrowings outstanding under the Company’s non-U.S. subsidiaries’ credit facilities.

At June 30, 2015 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 June 30, 2015 the quarterly interest rate was 0.63 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 billion. Approximately $900 million was used to finance the ARINC acquisition and approximately $200 million was used to refinance 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).

On May 6, 2009, the Company issued $300 million of 5.25 percent fixed rate unsecured debt due July 15, 2019 (the 2019 Notes). In January 2010, the Company entered into interest rate swap contracts which effectively converted $150 million of the 2019 Notes to floating rate debt based on six-month LIBOR plus 1.235 percent. In June 2015, the company entered into interest rate swap contracts which effectively converted the remaining $150 million of the 2019 Notes to floating rate debt based on three-month LIBOR plus 3.56 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.

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. During the nine months ended June 30, 2015, the Company made contributions to the non-U.S. plans and the U.S. non-qualified pension plan of $11 million.

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 June 30, 2015.

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 June 30, 2015 and 2014, the effective income tax rate from continuing operations was 24.9 percent and 28.8 percent, respectively. The lower current year effective income tax rate from continuing operations was primarily due to favorable adjustments related to the remeasurement of certain prior year tax positions.

During the nine months ended June 30, 2015 and 2014, the effective income tax rate from continuing operations was 26.7 percent and 29.3 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 and favorable remeasurement of certain prior year tax positions. These favorable adjustments were partially offset by the absence of the recognition of a tax benefit related to the Extraterritorial Income Exclusions claimed in prior years.

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 for the tax years ended December 31, 2008 and prior are closed to further adjustments by the IRS. The IRS is currently auditing ARINC's tax returns for tax years ended December 31, 2009 and December 31, 2012. 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 $124 million and $166 million during the nine months ended June 30, 2015 and 2014, respectively.

The Company has gross unrecognized tax benefits recorded within Other Liabilities in the Condensed Consolidated Statement of Financial Position of $42 million and $48 million as of June 30, 2015 and September 30, 2014, respectively. The total amount of unrecognized tax benefits that, if recognized, would affect the effective income tax rate was $15 million and $25 million as of June 30, 2015 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 $15 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 June 30, 2015 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 and $1 million during the nine months ended June 30, 2015 and 2014, 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.

(Unaudited)

The fair value of the Company's financial assets and liabilities measured at fair value on a recurring basis as of June 30, 2015 and September 30, 2014 are as follows:

		June 30, 2015			September 30, 2014
(in millions)	Fair Value Hierarchy	Fair Value Asset (Liability)			Fair Value Asset (Liability)
Deferred compensation plan investments	Level 1	$	52		$	50
Interest rate swap assets	Level 2	21			18
Foreign currency forward exchange contract assets	Level 2	9			6
Foreign currency forward exchange contract liabilities	Level 2	(13		)	(9		)

There were no nonfinancial assets or nonfinancial liabilities recognized at fair value on a nonrecurring basis and there were no transfers between Levels of the fair value hierarchy during the nine months ended June 30, 2015 or 2014.

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

	Asset (Liability)
	June 30, 2015						September 30, 2014
(in millions)	Carrying Amount			Fair Value			Carrying Amount			Fair Value
Cash and cash equivalents	$	294		$	294		$	323		$	323
Short-term debt	(745		)	(745		)	(504		)	(504		)
Long-term debt	(1,646		)	(1,716		)	(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.

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. To help meet this objective, the Company may use financial instruments in the form of interest rate swaps. In January 2010, the Company entered into two interest rate swap contracts 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. In June 2015, the Company entered into two interest rate swap contracts which expire on July 15, 2019 and effectively converted the remaining $150 million of the 2019 Notes to floating rate debt based on three-month LIBOR plus 3.56 percent (collectively the 2019 Swaps).

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.

The Company designated both the 2019 and the 2023 Swaps (the Swaps) as fair value hedges. The Swaps are recorded within Other Assets at a fair value of $21 million, offset by a fair value adjustment to Long-term Debt (Note 10) of $21 million at June 30, 2015. 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 June 30, 2015 and September 30, 2014, the Company had outstanding foreign currency forward exchange contracts with notional amounts of $339 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 June 30, 2015 and September 30, 2014 are as follows:

		Asset Derivatives
(in millions)	Classification	June 30, 2015		September 30, 2014
Foreign currency forward exchange contracts	Other current assets	$	9	$	6
Interest rate swaps	Other assets	21		18

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 June 30, 2015 there were undesignated foreign currency forward exchange contracts classified within Other current assets of $1 million and Other current liabilities of $2 million.

There was no significant impact to the Company’s earnings related to the ineffective portion of any hedging instruments during the nine months ended June 30, 2015. In addition, there was no significant impact to the Company’s earnings when a hedged firm commitment no longer qualified as a fair value hedge or when a hedged forecasted transaction no longer qualified as a cash flow hedge during the three and nine months ended June 30, 2015.

The Company did not have any hedges with credit-risk-related contingent features or that required the posting of collateral as of June 30, 2015. The cash flows from derivative contracts are recorded in operating activities in the Condensed Consolidated Statement of Cash Flows.

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 June 30, 2015 was 61 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:

	Nine Months Ended
	June 30
(in millions)	2015			2014
Balance at beginning of year	$	104		$	121

Changes in estimates for prior years	(7		)	(12		)
Foreign currency translation adjustments and other	(2		)	(1		)
Balance at June 30	$	94		$	109

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 June 30, 2015, 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 June 30, 2015, 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 June 30, 2015 were $269 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.

25

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 June 30, 2015, 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 June 30, 2015, 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 June 30, 2015, the Company has completed all cash payments associated with these actions.

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 June 30, 2015, the Company has made cash severance payments of approximately $31 million related to the 2012 restructuring action. As of June 30, 2015, $4 million of employee separation costs related to the 2012 action remain 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 commercial air transport and business and regional aircraft OEMs, 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 billion. 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 March 20, 2015, we acquired Pacific Avionics for $24 million. Pacific Avionics specializes in technologies used for wireless information distribution, including in-flight entertainment and connectivity, and is included in the Commercial Systems segment. The acquisition of Pacific Avionics will further enhance the capabilities of our existing cabin products and information management offerings.

During the first nine months of 2015, total revenues increased 8 percent, driven by the ARINC acquisition and an 8 percent increase in Commercial Systems revenues. Diluted earnings per share from continuing operations increased 17 percent to $3.81, due to the ARINC acquisition, higher earnings from Commercial Systems sales growth, the retroactive benefit of the Federal R&D Tax Credit and favorable adjustments related to the remeasurement of certain prior year tax positions.

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. Inclusive of this legislation, we expect our effective income tax rate for 2015 to be about 28 percent.

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

• total sales in the range of $5.25 billion to $5.3 billion (updated from $5.2 billion to $5.3 billion)

• diluted earnings per share in the range of $5.15 to $5.25 (updated from $5.10 to $5.30)

• cash provided by operating activities in the range of $725 million to $775 million (updated from $700 million to $800 million)

• capital expenditures of about $200 million

• total research and development investment of about $1 billion⁽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 and nine months ended June 30, 2015 and 2014 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.

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 $11 million, or 1 percent, primarily due to the following:

• $16 million from higher sales volume in Commercial Systems and Information Management Services

• $4 million from higher amortization of pre-production engineering costs

• partially offset by $8 million of lower cost of sales from lower sales volume and other cost savings initiatives in Government Systems

⁽¹⁾ Research and development expenses for the Information Management Services segment 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.

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 $14 million and $10 million for the three months ended June 30, 2015 and 2014, 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 June 30, 2015 increased $21 million from the same period last year. The customer-funded portion of R&D expense increased $23 million primarily due to higher development expenditures for various international programs in Commercial Systems and data link programs in Government Systems, as well as higher amortization of pre-production engineering costs in Commercial Systems and Government Systems. The $2 million decrease in company-funded R&D was principally driven by a wind down in development expenditures for the Embraer Legacy program in Commercial Systems.

In addition to the R&D expenses above, development expenditures incurred on the Boeing 737 MAX platform and Bombardier CSeries and Global 7000/8000 programs resulted in a net $34 million increase to our investments in pre-production engineering programs capitalized within inventory. The net increase of $34 million for the three months ended June 30, 2015 was $9 million less than the $43 million net increase in pre-production engineering costs capitalized within inventory during the three months ended June 30, 2014 primarily due to lower development expenditures for the Airbus A350 program. Refer to Note 6 of the Notes to Condensed Consolidated Financial Statements for further discussion of our incremental investments in pre-production engineering effort.

(in millions)	2015			2014
Sales	$	456		$	313
Percent increase	46		%

Total Information Management Services sales increased $143 million, primarily due to a $131 million inorganic increase from 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 prior to 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 was divested on March 10, 2015. The supplemental pro-forma data is not necessarily indicative of results that actually would have occurred had the acquisition truly been consummated prior to October 1, 2013. On a pro-forma basis, sales for the Information Management Services segment would be $456 million and $419 million for the nine months ended June 30, 2015 and 2014, respectively. The $37 million, or 9 percent, increase in the pro-forma sales was primarily due to the following:

• double-digit sales growth in aviation related sales, including GLOBALink^SM and ARINCDirect^SM  

• higher rail related sales due to certain unfavorable contract adjustments recorded in the first quarter of fiscal 2014

• partially offset by lower sales due to the exit of certain government programs

Other retirement benefits	3			2		8			7
Net benefit expense	$	1		$	3	$	4		$	12

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 $6 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 nine months ended June 30, 2015, 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, interest rates and actuarial assumptions. 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, compared to $10 million of expense in 2014.

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 generally the result of the tax benefits derived from the Federal R&D Tax Credit, the Domestic Manufacturing Deduction, and the results of global income tax examinations.

43

During the three months ended June 30, 2015 and 2014, the effective income tax rate from continuing operations was 24.9 percent and 28.8 percent, respectively. The lower current year effective income tax rate from continuing operations was primarily due to favorable adjustments related to the remeasurement of certain prior year tax positions.

During the nine months ended June 30, 2015 and 2014, the effective income tax rate from continuing operations was 26.7 percent and 29.3 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 and favorable remeasurement of certain prior year tax positions. These favorable adjustments were partially offset by the absence of the recognition of a tax benefit related to the Extraterritorial Income Exclusions claimed in prior years.

For fiscal year 2015, our effective income tax rate is projected to be about 28 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.

	Nine Months Ended June 30
(in millions)	2015		2014
Cash provided by operating activities from continuing operations	$	341	$	265

The $76 million increase in cash provided by operating activities during the nine months ended June 30, 2015 compared to the same period last year was primarily due to the following:

• cash receipts from customers increased by $170 million to $3.764 billion in the nine months ended June 30, 2015 compared to $3.594 billion in the nine months ended June 30, 2014. The increase in cash receipts from customers was less than the sales volume increase of $283 million due to the timing of sales and collection of receivables

• cash payments for income taxes decreased $42 million to $124 million during the first nine months of fiscal year 2015 compared to $166 million during the same period last year. The decrease in cash used for income tax payments was primarily from the retroactive reinstatement of the Federal R&D tax credit and bonus depreciation as a result of the Tax Increase Prevention Act of 2014

• the above items were partially offset by higher payments for production inventory and other operating costs which increased $131 million to $3.117 billion for the nine months ended June 30, 2015 compared to $2.986 billion during the nine months ended June 30, 2014. The increased payments for operating costs primarily resulted from higher sales volume

Cash (used for) investing activities from continuing operations	$	(187	)	$	(1,497	)

44

Cash used for investing activities for the nine months ended June 30, 2015 decreased $1.310 billion compared to the nine months ended June 30, 2014 primarily due to the following:

• we paid $1.405 billion for the December 2013 acquisition of ARINC

• the above item was partially offset by a $40 million increase in cash payments for property additions for the nine months ended June 30, 2015, 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

• also, we paid $24 million for the March 2015 acquisition of Pacific Avionics

Financing Activities

	Nine Months Ended June 30
(in millions)	2015			2014
Cash (used for) provided by financing activities from continuing operations	$	(153	)	$	1,316

The $1.469 billion increase in cash used for financing activities during the nine months ended June 30, 2015 compared to the nine months ended June 30, 2014 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 borrowings decreased $379 million. During the nine months ended June 30, 2015, net proceeds from short-term commercial paper borrowings were $241 million, compared to net proceeds of $620 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 $219 million to $330 million during the nine months ended June 30, 2015, compared to $111 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 June 30, 2015 and September 30, 2014 are as follows:

(in millions)	June 30, 2015			September 30, 2014
Cash and cash equivalents	$	294		$	323
Short-term debt	(745		)	(504		)
Long-term debt, net	(1,667		)	(1,663		)
Net debt (1)	$	(2,118	)	$	(1,844	)
Total equity	$	2,055		$	1,889
Debt to total capitalization (2)	54		%	53		%
Net debt to total capitalization (3)	51		%	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 billion. 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 billion, 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.

As of June 30, 2015, approximately 81 percent of our cash and cash equivalents reside 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 commercial paper. Under our commercial paper program, we may sell up to $1 billion 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 June 30, 2015, short-term commercial paper borrowings outstanding were $745 million with a weighted-average interest rate and maturity period of 0.51 percent and 28 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 nine months ended June 30, 2015 was $903 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 replaced 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 June 30, 2015 based on this financial covenant was 42 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 June 30, 2015:

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 June 30, 2015 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. Actual results may differ materially from those projected as a result of certain risks and uncertainties, including, but not limited to the financial condition of our customers and suppliers, including bankruptcies; the health of the global economy, including potential deterioration in economic and financial market conditions; adjustments to the commercial OEM production rates and the aftermarket; the impacts of natural disasters, including operational disruption, potential supply shortages and other economic impacts; cybersecurity threats, including the potential misappropriation of assets or other sensitive information, corruption of data or operational disruption; delays related to the awards of domestic and internal contracts; delays in customer programs, including new aircraft programs entering into service later than anticipated; the continued support for military transformation and modernization programs; potential impact of volatility in oil prices, currency exchange rates or interest rates on the commercial aerospace industry or our business; 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; unfavorable 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 may employ financial instruments in the form of interest rate swaps to help meet this objective.

47

At June 30, 2015, we had the following unsecured long-term debt obligations:

	June 30, 2015
(in millions)	Interest Rate	Carrying Value		Fair Value
$400 Notes due 2043	4.80%	$	398	$	414
$400 Notes due 2023	3.70%	399		410
$250 Notes due 2021	3.10%	250		258
$300 Notes due 2019	5.25%	299		334
$300 Notes due 2016	3 month LIBOR plus 0.35%	300		300

In June 2015, we entered into interest rate swap contracts which effectively converted $150 million of the Notes due 2019 to floating rate debt based on three month LIBOR plus 3.56 percent.

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 $31 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 $33 million. The fair value of the $500 million notional value of interest rate swap contracts was a $21 million net asset at June 30, 2015. A hypothetical 10 percent increase or decrease in average market interest rates would decrease or increase the fair value of our interest rate swap contracts by $5 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 $339 million and $575 million at June 30, 2015 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 $4 million net liability at June 30, 2015 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 June 30, 2015 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 June 30, 2015 by $3 million. For more information related to outstanding foreign 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 June 30, 2015, 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 June 30, 2015 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.

[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 divested, as detailed in Note 4.

Guarantees and Indemnifications Abstract

Guarantees and Indemnifications

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:

	Nine Months Ended

(in millions)	2015			2014

Changes in estimates for prior years	(7		)	(12		)
Foreign currency translation adjustments and other	(2		)	(1		)
Balance at June 30	$	94		$	109

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 June 30, 2015, 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 June 30, 2015, 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 June 30, 2015 were $269 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.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Recently Issued Accounting Standards

Recently Issued Accounting Standards

In May 2014, the Financial Accounting Standards Board (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 use of either a retrospective or cumulative effect transition method. Based upon the FASB's recent decision to approve a one year delay in implementation, the new standard is now effective for the Company in fiscal 2019, with early adoption permitted, but not earlier than fiscal 2018. The Company is currently evaluating the transition methods allowed under the new standard and the effect the standard will have on the Company's 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.

In April 2014, the 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.

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.

Restructuring, Pension Settlement, and Asset Impairment Charges, Net

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 June 30, 2015, the Company has completed all cash payments associated with these actions.

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 June 30, 2015, the Company has made cash severance payments of approximately $31 million related to the 2012 restructuring action. As of June 30, 2015, $4 million of employee separation costs related to the 2012 action remain to be paid in future periods.

Accounting Policies [Abstract]

Preproduction Engineering Costs Policy

The Company defers certain pre-production engineering costs during the development phase of a program in connection with long-term supply arrangements that contain contractual guarantees for reimbursement from customers. Such customer guarantees generally take the form of a minimum order quantity with quantified reimbursement amounts if the minimum order quantity is not taken by the customer. These costs are deferred to the extent of the contractual guarantees and are amortized over their estimated useful lives using a units-of-delivery method, up to 15 years. This amortization expense is included as a component of cost of sales. Amortization is based on the Company's expectation of delivery rates on a program-by-program basis and begins when the Company starts recognizing revenue as the Company delivers equipment for the program. The estimated useful life is limited to the amount of time the Company is virtually assured to earn revenues 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.

Customer Incentives, Policy

Rockwell Collins provides up-front sales incentives prior to delivering products or performing services to certain commercial customers in connection with sales contracts. Up-front sales incentives are recorded as a Customer relationship intangible asset and are amortized using a units-of-delivery method over the period the Company has received a contractually enforceable right related to the incentives, up to 15 years. Amortization is based on the Company's expectation of delivery rates on a program-by-program basis. Amortization begins when the Company starts recognizing revenue as the Company delivers equipment for the program.

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, June 30 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 and nine months ended June 30, 2015 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.

As discussed in Note 4, Discontinued Operations and Divestitures, on March 10, 2015, the Company divested ARINC's Aerospace Systems Engineering and Support (ASES) business, which provides military aircraft integration and modifications, maintenance and logistics and support. On July 25, 2014, the Company divested its satellite communication systems business, formerly known as Datapath, Inc. (Datapath). As a result, the Datapath and ASES businesses have been accounted for as discontinued operations for all periods presented.

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 June 30, 2015 and 2014, the effective income tax rate from continuing operations was 24.9 percent and 28.8 percent, respectively. The lower current year effective income tax rate from continuing operations was primarily due to favorable adjustments related to the remeasurement of certain prior year tax positions.

During the nine months ended June 30, 2015 and 2014, the effective income tax rate from continuing operations was 26.7 percent and 29.3 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 and favorable remeasurement of certain prior year tax positions. These favorable adjustments were partially offset by the absence of the recognition of a tax benefit related to the Extraterritorial Income Exclusions claimed in prior years.

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 for the tax years ended December 31, 2008 and prior are closed to further adjustments by the IRS. The IRS is currently auditing ARINC's tax returns for tax years ended December 31, 2009 and December 31, 2012. 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 $124 million and $166 million during the nine months ended June 30, 2015 and 2014, respectively.

The Company has gross unrecognized tax benefits recorded within Other Liabilities in the Condensed Consolidated Statement of Financial Position of $42 million and $48 million as of June 30, 2015 and September 30, 2014, respectively. The total amount of unrecognized tax benefits that, if recognized, would affect the effective income tax rate was $15 million and $25 million as of June 30, 2015 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 $15 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 June 30, 2015 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 and $1 million during the nine months ended June 30, 2015 and 2014, respectively.

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. To help meet this objective, the Company may use financial instruments in the form of interest rate swaps. In January 2010, the Company entered into two interest rate swap contracts 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. In June 2015, the Company entered into two interest rate swap contracts which expire on July 15, 2019 and effectively converted the remaining $150 million of the 2019 Notes to floating rate debt based on three-month LIBOR plus 3.56 percent (collectively the 2019 Swaps).

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.

The Company designated both the 2019 and the 2023 Swaps (the Swaps) as fair value hedges. The Swaps are recorded within Other Assets at a fair value of $21 million, offset by a fair value adjustment to Long-term Debt (Note 10) of $21 million at June 30, 2015. 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 June 30, 2015 and September 30, 2014, the Company had outstanding foreign currency forward exchange contracts with notional amounts of $339 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 June 30, 2015 and September 30, 2014 are as follows:

		Liability Derivatives
(in millions)	Classification	June 30, 2015		September 30, 2014

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 June 30, 2015 there were undesignated foreign currency forward exchange contracts classified within Other current assets of $1 million and Other current liabilities of $2 million.

The effect of derivative instruments on the Condensed Consolidated Statement of Operations for the three and nine months ended June 30, 2015 and 2014 is as follows:

There was no significant impact to the Company’s earnings related to the ineffective portion of any hedging instruments during the nine months ended June 30, 2015. In addition, there was no significant impact to the Company’s earnings when a hedged firm commitment no longer qualified as a fair value hedge or when a hedged forecasted transaction no longer qualified as a cash flow hedge during the three and nine months ended June 30, 2015.

The Company did not have any hedges with credit-risk-related contingent features or that required the posting of collateral as of June 30, 2015. The cash flows from derivative contracts are recorded in operating activities in the Condensed Consolidated Statement of Cash Flows.

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 June 30, 2015 was 61 months.

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 June 30, 2015, short-term commercial paper borrowings outstanding were $745 million with a weighted-average interest rate and maturity period of 0.51 percent and 28 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 42 percent as of June 30, 2015. 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.

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.

The net proceeds after discounts and debt issuance costs from the December 16, 2013 debt issuances totaled $1.089 billion. Approximately $900 million was used to finance the ARINC acquisition and approximately $200 million was used to refinance notes that matured on December 1, 2013. The remaining ARINC purchase price was funded using commercial paper proceeds.

In June 2015, the company entered into interest rate swap contracts which effectively converted the remaining $150 million of the 2019 Notes to floating rate debt based on three-month LIBOR plus 3.56 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 June 30, 2015 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. During the nine months ended June 30, 2015, the Company made contributions to the non-U.S. plans and the U.S. non-qualified pension plan of $11 million.

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 June 30, 2015.

Discontinued Operations and Divestitures

Discontinued Operations and Divestitures

On March 10, 2015, the Company sold 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. The sale pricewas $3 million, and additional post-closing consideration of up to $4 million may be received. The Company recognized a pre-tax loss of $5 million ($3 million after-tax) related to the ASES divestiture. The operating results of ASES, including the loss realized on the disposition, have been included within discontinued operations in the Company's Condensed Consolidated Statement of Operations for all periods presented.

On July 25, 2014, the Company sold its satellite communication systems business formerly known as Datapath. The sale 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 the Company's 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.

Results of discontinued operations are as follows:

	Three Months Ended					Nine Months Ended
	June 30					June 30
(in millions)	2015		2014			2015			2014
Sales	$	—	$	31		$	18		$	74
Loss from discontinued operations before income taxes	—		(13		)	(13		)	(17		)
Income tax benefit from discontinued operations	—		8			5			9

During the first quarter of 2014, 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. The divestiture of this business is part of the Company's 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.

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 June 30, 2015 and September 30, 2014 are as follows:

		June 30, 2015			September 30, 2014
(in millions)	Fair Value Hierarchy	Fair Value Asset (Liability)			Fair Value Asset (Liability)
Deferred compensation plan investments	Level 1	$	52		$	50
Interest rate swap assets	Level 2	21			18
Foreign currency forward exchange contract assets	Level 2	9			6
Foreign currency forward exchange contract liabilities	Level 2	(13		)	(9		)

There were no nonfinancial assets or nonfinancial liabilities recognized at fair value on a nonrecurring basis and there were no transfers between Levels of the fair value hierarchy during the nine months ended June 30, 2015 or 2014.

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

	Asset (Liability)
	June 30, 2015						September 30, 2014
(in millions)	Carrying Amount			Fair Value			Carrying Amount			Fair Value
Cash and cash equivalents	$	294		$	294		$	323		$	323
Short-term debt	(745		)	(745		)	(504		)	(504		)
Long-term debt	(1,646		)	(1,716		)	(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.

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 June 30, 2015, the weighted average amortization period remaining for up-front sales incentives was approximately 10 years.

Anticipated annual amortization expense for intangible assets is as follows:

(in millions)	2015		2016		2017		2018		2019		Thereafter
Anticipated amortization expense for up-front sales incentives	$	14	$	17	$	17	$	20	$	23	$	143

Total	$	55	$	56	$	53	$	51	$	52	$	389

Amortization expense for intangible assets for the three and nine months ended June 30, 2015 was $15 million and $40 million, respectively, compared to $13 million and $34 million for the three and nine months ended June 30, 2014.

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

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:

(in millions)	2015		2016		2017		2018		2019		Thereafter
Anticipated amortization expense for pre-production engineering costs	$	47	$	55	$	83	$	103	$	118	$	604

Amortization expense for pre-production engineering costs for the three and nine months ended June 30, 2015 was $14 million and $35 million, respectively, compared to $10 million and $24 million for the three and nine months ended June 30, 2014. As of June 30, 2015, the weighted average amortization period remaining for pre-production engineering costs included in Inventories, net was approximately 11 years.

Investments in Equity Affiliates

Investments in equity affiliates primarily consist of eight 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.

During the second quarter of 2015, the Company established a new joint venture, ACCEL (Tianjin) Flight Simulation Co., Ltd (ACCEL), to develop and deliver commercial flight simulators in China. ACCEL is a 50 percent owned joint venture with Beijing Bluesky Aviation Technology, an AVIC subsidiary. The Company's share of earnings or losses of ACCEL are included in the operating results of the Commercial Systems Segment. Consistent with the terms of the joint venture agreement, the Company expects to contribute cash totaling $7 million to the joint venture later in fiscal 2015 and fiscal 2016.

The Company's remaining joint ventures are also 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. The results of Rockwell Collins CETC Avionics Co., Ltd (RCCAC) and AVIC Leihua Rockwell Collins Avionics Company (ALRAC) are included in the operating results of the Commercial Systems segment, and ADARI Aviation Technology Limited (ADARI) is included in the operating results of the Information Management Services segment.

In the normal course of business or pursuant to the underlying joint venture agreements, the Company may sell products or services to equity affiliates. The Company defers a portion of the profit generated from these sales equal to its ownership interest in the equity affiliates until the underlying product is ultimately sold to an unrelated third party. Sales to equity affiliates were $51 million and $139 million for the three and nine months ended June 30, 2015, respectively, and $42 million and $118 million for the three and nine months ended June 30, 2014, respectively. The deferred portion of profit generated from sales to equity affiliates was $1 million at June 30, 2015 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 $7 million for the three and nine months ended June 30, 2015, respectively, and $3 million and $8 million for the three and nine months ended June 30, 2014, respectively.

Environmental Remediation Obligations [Abstract]

Environmental Matters

Environmental Matters

The Company is subject to federal, state and local regulations relating to the discharge of substances into the environment, the disposal of hazardous wastes and other activities affecting the environment that have had and will continue to have an impact on the Company’s manufacturing operations. These environmental protection regulations may require the investigation and remediation of environmental impairments at current and previously owned or leased properties. In addition, lawsuits, claims and proceedings have been asserted on occasion against the Company alleging violations of environmental protection regulations, or seeking remediation of alleged environmental impairments, principally at previously owned or leased properties. As of June 30, 2015, 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 June 30, 2015, 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

Acquisitions

On March 20, 2015, the Company acquired 100 percent of the outstanding shares of Pacific Avionics Pty. Limited (Pacific Avionics), a Singapore-based company specializing in technologies used for wireless information distribution, including in-flight entertainment and connectivity. The purchase price, net of cash acquired, was $24 million. The Company is in the process of allocating the purchase price and obtaining a valuation for acquired intangible assets and their useful lives. Based on the Company's preliminary allocation of the purchase price, $9 million has been allocated to in process research and development (IPR&D) and $15 million to goodwill, none of which is deductible for tax purposes. The acquired IPR&D is recorded at fair value as an indefinite-lived intangible asset until the development is complete, at which time the asset will be considered a finite-lived intangible asset and amortized over its estimated useful life. The excess purchase price over net assets acquired, including intangible assets, reflects the Company's view that this acquisition will further enhance the Company's cabin products and information management services portfolios. Pacific Avionics is included within the Commercial Systems segment, and its results of operations have been included in the Company's operating results for the period subsequent to the completion of the acquisition on March 20, 2015. Pro-forma results of operations have not been presented because the effect of the acquisition is not material to the Company's consolidated results of operations.

On December 23, 2013, the Company acquired 100 percent of the outstanding common stock and voting interests of Radio Holdings, Inc., 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 billion, 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 divested, as detailed in Note 4.

The purchase price allocation resulted in the recognition of $1.087 billion of goodwill and $431 million of intangible assets with a weighted average useful life of approximately 15 years. None of the goodwill 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 ended June 30, 2015 and 2014, ARINC contributed sales of $140 million and $134 million, respectively, and net income of $21 million and $12 million, respectively. For the nine months ended June 30, 2015 and 2014, ARINC contributed sales of $421 million and $277 million, respectively, and net income of $47 million and $22 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 of $81 million from the sale 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 prior to 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 had been consummated prior to 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.

The unaudited supplemental pro-forma data above excludes the results of ASES, which the Company divested, 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 prior to October 1, 2013. These adjustments are net of any applicable tax impact and were included to arrive at the pro-forma results above.
