Johnson Controls, Inc.

Notes to Consolidated Financial Statements

March 31, 2015

(unaudited)

1. Financial Statements

In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments (which include normal recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows for the periods presented. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) have been omitted pursuant to the rules and regulations of the United States Securities and Exchange Commission (SEC). These consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Johnson Controls, Inc. (the "Company") Annual Report on Form 10-K for the year ended September 30, 2014. The results of operations for the three and six month periods ended March 31, 2015 are not necessarily indicative of results for the Company’s 2015 fiscal year because of seasonal and other factors.

The consolidated financial statements include the accounts of Johnson Controls, Inc. and its domestic and non-U.S. subsidiaries that are consolidated in conformity with U.S. GAAP. All significant intercompany transactions have been eliminated. Investments in partially-owned affiliates are accounted for by the equity method when the Company’s interest exceeds 20% and the Company does not have a controlling interest.

Under certain criteria as provided for in Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 810, "Consolidation," the Company may consolidate a partially-owned affiliate. To determine whether to consolidate a partially-owned affiliate, the Company first determines if the entity is a variable interest entity (VIE). An entity is considered to be a VIE if it has one of the following characteristics: 1) the entity is thinly capitalized; 2) residual equity holders do not control the entity; 3) equity holders are shielded from economic losses or do not participate fully in the entity’s residual economics; or 4) the entity was established with non-substantive voting. If the entity meets one of these characteristics, the Company then determines if it is the primary beneficiary of the VIE. The party with the power to direct activities of the VIE that most significantly impact the VIE’s economic performance and the potential to absorb benefits or losses that could be significant to the VIE is considered the primary beneficiary and consolidates the VIE. If the entity is not considered a VIE, then the Company applies the voting interest model to determine whether or not the Company shall consolidate the partially-owned affiliate.

Consolidated VIEs

Based upon the criteria set forth in ASC 810, the Company has determined that it was the primary beneficiary in three VIEs for the reporting periods ended March 31, 2015, September 30, 2014 and March 31, 2014, as the Company absorbs significant economics of the entities and has the power to direct the activities that are considered most significant to the entities.

Two of the VIEs manufacture products in North America for the automotive industry. The Company funds the entities’ short term liquidity needs through revolving credit facilities and has the power to direct the activities that are considered most significant to the entities through its key customer supply relationships.

In fiscal 2012, a pre-existing VIE accounted for under the equity method was reorganized into three separate investments as a result of the counterparty exercising its option to put its interest to the Company. The Company acquired additional interests in two of the reorganized group entities. The reorganized group entities are considered to be VIEs as the other owner party has been provided decision making rights but does not have equity at risk. The Company is considered the primary beneficiary of one of the entities due to the Company’s power pertaining to decisions over significant activities of the entity. As such, this VIE has been consolidated within the Company’s consolidated statements of financial position. The impact of consolidation of the entity on the Company’s consolidated statements of income for the three and six month periods ended March 31, 2015 and 2014 was not material. The VIE is named as a co-obligor under a third party debt agreement of $164 million, maturing in fiscal 2020, under which it could become subject to paying more than its allocated share of the third party debt in the event of bankruptcy of one or more of the other co-obligors. The other co-obligors, all related parties in which the Company is an equity investor, consist of the remaining group entities involved in the reorganization. As part of the overall reorganization transaction, the Company has also provided financial support to the group entities in the form of loans totaling $58 million, which are subordinate to the third party debt agreement. The Company is a significant customer of certain co-obligors, resulting in a remote possibility of loss. Additionally, the Company is subject to a floor guaranty expiring in fiscal 2022; in the event that the other owner party no longer owns any part of the group entities due to sale or transfer, the Company has guaranteed

Notes to Consolidated Financial Statements

(unaudited)

that the proceeds received from the sale or transfer will not be less than $25 million. The Company has partnered with the group entities to design and manufacture battery components for the Power Solutions business.

The carrying amounts and classification of assets (none of which are restricted) and liabilities included in the Company’s consolidated statements of financial position for the consolidated VIEs are as follows (in millions):

	March 31, 2015		September 30, 2014		March 31, 2014
Current assets	$	269	$	218	$	296
Noncurrent assets	134		138		137
Total assets	$	403	$	356	$	433
Current liabilities	$	200	$	189	$	195
Noncurrent liabilities	35		37		38
Total liabilities	$	235	$	226	$	233

The Company did not have a significant variable interest in any other consolidated VIEs for the presented reporting periods.

Nonconsolidated VIEs

As mentioned previously within the "Consolidated VIEs" section above, in fisca1 2012, a pre-existing VIE was reorganized into three separate investments as a result of the counterparty exercising its option to put its interest to the Company. The reorganized group entities are considered to be VIEs as the other owner party has been provided decision making rights but does not have equity at risk. The Company is not considered to be the primary beneficiary of two of the entities as the Company cannot make key operating decisions considered to be most significant to the VIEs. Therefore, the entities are accounted for under the equity method of accounting as the Company’s interest exceeds 20% and the Company does not have a controlling interest. The Company’s maximum exposure to loss includes the partially-owned affiliate investment balance of $60 million, $59 million and $60 million at March 31, 2015, September 30, 2014 and March 31, 2014, respectively, as well as the subordinated loan from the Company, third party debt agreement and floor guaranty mentioned previously within the "Consolidated VIEs" section above. Current liabilities due to the VIEs are not material and represent normal course of business trade payables for all presented periods.

The Company did not have a significant variable interest in any other unconsolidated VIEs for the presented reporting periods.

Restricted Cash

At March 31, 2015, September 30, 2014 and March 31, 2014, the Company held restricted cash of approximately $8 million, $4 million and $22 million, respectively, within cash and cash equivalents. These amounts were collected from customers for payment of maintenance costs under contract, and withdrawals are restricted for this purpose.

Retrospective Changes

At March 31, 2015, the Company determined that its Building Efficiency Global Workplace Solutions (GWS) segment met the criteria to be classified as a discontinued operation, which required retrospective application to financial information for all periods presented. Refer to Note 4, "Discontinued Operations," of the notes to consolidated financial statements for further information regarding the Company's discontinued operations.

2.  New Accounting Standards

In April 2015, the FASB issued Accounting Standards Update (ASU) No. 2015-03, "Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs." ASU No. 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the debt liability.

Johnson Controls, Inc.

Notes to Consolidated Financial Statements

March 31, 2015

(unaudited)

ASU No. 2015-03 will be effective retrospectively for the Company for the quarter ending December 31, 2016, with early adoption permitted. The adoption of this guidance is not expected to have a significant impact on the Company's consolidated financial statements.

In February 2015, the FASB issued ASU No. 2015-02, "Consolidation (Topic 810): Amendments to the Consolidation Analysis." ASU No. 2015-02 amends the analysis performed to determine whether a reporting entity should consolidate certain types of legal entities. ASU No. 2015-02 will be effective retrospectively for the Company for the quarter ending December 31, 2016, with early adoption permitted. The Company is currently assessing the impact adoption of this guidance will have on its consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)." ASU No. 2014-09 clarifies the principles for recognizing revenue when an entity either enters into a contract with customers to transfer goods or services or enters into a contract for the transfer of non-financial assets. The original standard will be effective retrospectively for the Company for the quarter ending December 31, 2017; however in April 2015, the FASB proposed a one-year deferral of the standard. If the deferral is approved, the new standard will become effective retrospectively for the Company for the quarter ending December 31, 2018, with early adoption permitted, but not before the original effective date. The Company is currently assessing the impact adoption of this guidance will have on its consolidated financial statements.

In April 2014, the FASB issued ASU No. 2014-08, "Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity." ASU No. 2014-08 limits discontinued operations reporting to situations where the disposal represents a strategic shift that has (or will have) a major effect on an entity's operations and financial results, and requires expanded disclosures for discontinued operations. ASU No. 2014-08 will be effective prospectively for the Company for disposals that occur during or after the quarter ending December 31, 2015, with early adoption permitted in certain instances. The significance of this guidance for the Company is dependent on any future dispositions or disposals.

In July 2013, the FASB issued ASU No. 2013-11, "Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists." ASU No. 2013-11 clarifies that companies should present an unrecognized tax benefit as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward. ASU No. 2013-11 was effective for the Company for the quarter ending December 31, 2014. The adoption of this guidance did not have a significant impact on the Company's consolidated financial statements.

3. Acquisitions and Divestitures

In the first six months of fiscal 2015, the Company completed three acquisitions for a combined purchase price, net of cash acquired, of $47 million, $18 million of which was paid in the six months ended March 31, 2015. The acquisitions in the aggregate were not material to the Company’s consolidated financial statements. In connection with the acquisitions, the Company recorded goodwill of $9 million.

In the first six months of fiscal 2015, the Company adjusted the purchase price allocation of the fiscal 2014 acquisition of Air Distribution Technologies Inc. (ADT). The adjustment was made as a result of a true-up to the purchase price in the amount of $4 million, all of which was paid in the six months ended March 31, 2015. Also, in connection with this acquisition, the Company recorded additional goodwill of $21 million in fiscal 2015 related to the purchase price allocations. In fiscal 2014, the Company recorded goodwill of $837 million in the Building Efficiency Other segment as a result of the ADT acquisition. The purchase price allocations may be subsequently adjusted to reflect final valuation studies.

In January 2015, the Company signed a definitive agreement to create a joint venture with Hitachi to expand its Building Efficiency product offerings. The formation of the joint venture is expected to close near the end of fiscal 2015, pending regulatory approvals.

On March 31, 2015, the Company announced that it had reached a definitive agreement to sell its GWS business to CBRE Group Inc., subject to regulatory and other approvals. Estimated proceeds are expected to be $1.475 billion and the sale is expected to close near the end of fiscal 2015. At March 31, 2015, the Company determined that the GWS segment met the

(unaudited)

criteria to be classified as a discontinued operation. Refer to Note 4, "Discontinued Operations," of the notes to the consolidated financial statements for further disclosure related to the Company's discontinued operations.

In the three months ended March 31, 2015, the Company completed the sale of its interests in two GWS joint ventures to Brookfield Asset Management, Inc. The selling price, net of cash divested, was $141 million, all of which was received as of March 31, 2015. In connection with the sale, the Company recorded a $200 million gain, $127 million net of tax, within income from discontinued operations, net of tax on the consolidated statements of income and reduced goodwill in assets held for sale by $20 million.

In the first six months of fiscal 2014, the Company completed two acquisitions for a combined purchase price, net of cash acquired, of $128 million, all of which was paid in the six months ended March 31, 2014. The acquisitions in the aggregate were not material to the Company's consolidated financial statements. In connection with the acquisitions, the Company recorded goodwill of $100 million. As a result of one of the acquisitions, which increased the Company's ownership from a noncontrolling to controlling interest, the Company recorded a non-cash gain of $19 million in equity income for the Power Solutions business to adjust the Company's existing equity investment in the partially-owned affiliate to fair value.

In the first six months of fiscal 2014, the Company completed one divestiture for a sales price of $13 million, all of which was received as of March 31, 2014. The divestiture was not material to the Company’s consolidated financial statements. In connection with the divestiture, the Company recorded a gain, net of transaction costs, of $9 million in the Automotive Experience Interiors segment. There was no change in goodwill as a result of this transaction.

In the first six months of fiscal 2014, the Company adjusted the purchase price allocation of certain fiscal 2013 acquisitions and recorded additional goodwill of $2 million.

4. Discontinued Operations

In the second quarter of fiscal 2015, the Company completed the sale of its interests in two GWS joint ventures to Brookfield Asset Management, Inc. On March 31, 2015, the Company announced that it had reached a definitive agreement to sell the remainder of the GWS business to CBRE Group Inc., subject to regulatory and other approvals. The agreement includes a 10-year strategic relationship between the Company and CBRE. The Company will be the preferred provider of HVAC equipment, building automation systems and related services to the portfolio of real estate and corporate facilities managed globally by CBRE and GWS. The Company also expects to engage GWS for facility management services. The annual cash flows resulting from these activities with the legacy GWS business are not expected to be significant. The sale is expected to close near the end of fiscal 2015.

At March 31, 2015, the Company determined that its GWS segment met the criteria to be classified as a discontinued operation, which required retrospective application to financial information for all periods presented. The Company did not allocate any general corporate overhead to discontinued operations. The assets and liabilities of the GWS segment were reflected as held for sale in the consolidated statements of financial position at March 31, 2015 and September 30, 2014.

For the three and six months ended March 31, 2015, the income from discontinued operations before income taxes included a $200 million gain on divestiture of the Company's interest in two GWS joint ventures. For the three and six months ended March 31, 2015, the income from discontinued operations before income taxes included current year transaction costs of $10 million and $17 million, respectively.

For the three and six months ended March 31, 2015, the effective tax rate was greater than the U.S. federal statutory rate of 35% primarily due to a second quarter discrete non-cash tax charge of $67 million related to the change in the Company's assertion over reinvestment of foreign undistributed earnings as well as the tax consequences of the sale of the GWS joint ventures, partially offset by foreign tax rate differentials. For the three and six months ended March 31, 2014, the effective tax rate was less than the U.S. federal statutory rate of 35% primarily due to foreign tax rate differentials.

In the fourth quarter of fiscal 2013, the Company completed its divestiture of its Automotive Experience Electronics' HomeLink® product line to Gentex Corporation. In the second quarter of fiscal 2014, the Company announced that it had reached a definitive agreement to sell the remainder of the Automotive Experience Electronics business to Visteon Corporation, subject to regulatory and other approvals. The sale closed on July 1, 2014. At March 31, 2014, the Company determined that the Automotive Experience Electronics segment met the criteria to be classified as a discontinued operation, which required retrospective application to financial information for all periods presented. The Company did not allocate any general corporate overhead to discontinued operations. The assets and liabilities of the Automotive Experience Electronics segment were reflected as held for sale in the consolidated statements of financial position at March 31, 2014.

For the three and six months ended March 31, 2014, the effective tax rate was greater than the U.S. federal statutory rate of 35% primarily due to a second quarter discrete non-cash tax charge of $180 million related to the repatriation of foreign cash associated with the divestiture of the Electronics business and unbenefited foreign losses.

Assets and Liabilities Held for Sale

The Company has determined that certain of its businesses met the criteria to be classified as held for sale. In April 2015, the Company signed an agreement formally establishing the previously announced automotive interiors joint venture with Yanfeng Automotive Trim Systems. The formation of the joint venture is expected to close in the fourth quarter of fiscal 2015, pending regulatory approvals. At March 31, 2015, the Company determined certain product lines of the Automotive Experience Interiors segment which are not to be contributed to the aforementioned automotive interiors joint venture met the criteria to be classified as held for sale. As a result, a majority of the Automotive Experience Interiors business met the criteria to be classified as held for sale.

The following table summarizes the carrying value of the Interiors and GWS assets and liabilities held for sale (in millions):

	March 31, 2015						September 30, 2014
	Interiors		Global Workplace Solutions		Total		Interiors		Global Workplace Solutions		Total
Cash and cash equivalents	$	—	$	—	$	—	$	—	$	20	$	20

Liabilities held for sale	$	858	$	653	$	1,511	$	833	$	968	$	1,801

These divestitures could result in a gain or loss on sale to the extent the ultimate selling price or contribution value differs from the carrying value of the net assets recorded for each business. The Interiors businesses classified as held for sale do not meet the criteria to be classified as a discontinued operation at March 31, 2015 primarily due to the Company's anticipated continuing involvement in these operations following a divestiture and the immateriality of certain product lines to the Company.

The Automotive Experience Electronics segment and the headliner and sun visor product lines were classified as held for sale beginning September 30, 2013. The headliner and sun visor product lines and the Automotive Experience Electronics segment were sold during the third and fourth quarters of fiscal 2014, respectively.

30, 2014 Automotive Experience Interiors business divestiture amount includes $12 million of goodwill transferred to noncurrent assets held for sale on the consolidated statement of financial position. The six months ended March 31, 2015 Automotive Experience Interiors business divestiture amount includes $9 million of goodwill transferred to noncurrent assets held for sale on the consolidated statement of financial position. Refer to Note 4, "Discontinued Operations," of the notes to consolidated financial statements for further information regarding the Company's assets and liabilities held for sale.

During the six months ended September 30, 2014, as a result of recent operating results, restructuring actions and expected future profitability, the Company's forecasted cash flow estimates used in the goodwill assessment were negatively impacted as of September 30, 2014 for the Building Efficiency Other - Latin America reporting unit. As a result, the Company concluded that the carrying value of the Building Efficiency Other - Latin America reporting unit exceeded its fair value as of September 30, 2014. The Company recorded a goodwill impairment charge of $47 million in the fourth quarter of fiscal 2014, which was determined by comparing the carrying value of the reporting unit's goodwill with the implied fair value of goodwill for the reporting unit. The Building Efficiency Other - Latin America reporting unit had no remaining goodwill at September 30, 2014.

The Company's impairment testing in the fourth quarter of fiscal 2014 indicated that the estimated fair value of the Building Efficiency Other - Middle East reporting unit exceeded its corresponding carrying amount including goodwill by approximately 9%. Accordingly, the Company has not recognized any impairment of goodwill associated with this reporting unit, which as of March 31, 2015 had a goodwill balance of $85 million. The Company continuously monitors for events and circumstances that could negatively impact the key assumptions in determining fair value, including long-term revenue growth projections, profitability, discount rates, recent market valuations from transactions by comparable companies, volatility in the Company's market capitalization, and general industry, market and macro-economic conditions. It is possible that future changes in such circumstances, or in the variables associated with the judgments, assumptions and estimates used in assessing the fair value of the reporting unit, would require the Company to record a non-cash impairment charge.

The assumptions included in the impairment test required judgment, and changes to the inputs could impact the results of the calculation. Other than management's internal projections of future cash flows, the primary assumptions used in the impairment test was the weighted-average cost of capital and long-term growth rates. Although the Company's cash flow forecasts are based on assumptions that are considered reasonable by management and consistent with the plans and estimates management is using to operate the underlying businesses, there are significant judgments in determining the expected future cash flows.

The Company’s other intangible assets, primarily from business acquisitions valued based on independent appraisals, consisted of (in millions):

	March 31, 2015							September 30, 2014							March 31, 2014

Amortization of other intangible assets for the three month periods ended March 31, 2015 and 2014 was $22 million and $20 million, respectively. Amortization of other intangible assets for the six month periods ended March 31, 2015 and 2014 was $46 million and $40 million, respectively.

8. Product Warranties

The Company offers warranties to its customers depending upon the specific product and terms of the customer purchase agreement. A typical warranty program requires that the Company replace defective products within a specified time period from the date of sale. The Company records an estimate for future warranty-related costs based on actual historical return rates and other known factors. Based on analysis of return rates and other factors, the Company’s warranty provisions are adjusted as necessary. The Company monitors its warranty activity and adjusts its reserve estimates when it is probable that future warranty costs will be different than those estimates.

The Company’s product warranty liability is recorded in the consolidated statements of financial position in other current liabilities if the warranty is less than one year and in other noncurrent liabilities if the warranty extends longer than one year.

The changes in the carrying amount of the Company’s total product warranty liability, including extended warranties for which deferred revenue is recorded, for the six months ended March 31, 2015 and 2014 were as follows (in millions):

9. Significant Restructuring and Impairment Costs

To better align its resources with its growth strategies and reduce the cost structure of its global operations to address the softness in certain underlying markets, the Company commits to restructuring plans as necessary.

In fiscal 2014, the Company committed to a significant restructuring plan (2014 Plan) and recorded $324 million of restructuring and impairment costs in the consolidated statements of income. This is the total amount incurred to date and the total amount expected to be incurred for this restructuring plan.

The Company's fiscal 2014, 2013 and 2012 restructuring plans included workforce reductions of approximately 20,600 employees (11,000 for the Automotive Experience business, 8,500 for the Building Efficiency business and 1,100 for the Power Solutions business). Restructuring charges associated with employee severance and termination benefits are paid over the severance period granted to each employee or on a lump sum basis in accordance with individual severance agreements. As of March 31, 2015, approximately 15,900 of the employees have been separated from the Company pursuant to the restructuring plans. In addition, the restructuring plans included twenty-eight plant closures (twenty for Automotive Experience, six for Building Efficiency and two for Power Solutions). As of March 31, 2015, seventeen of the twenty-eight plants have been closed.

Company management closely monitors its overall cost structure and continually analyzes each of its businesses for opportunities to consolidate current operations, improve operating efficiencies and locate facilities in low cost countries in close proximity to customers. This ongoing analysis includes a review of its manufacturing, engineering and purchasing operations, as well as the overall global footprint for all its businesses. Because of the importance of new vehicle sales by major automotive manufacturers to operations, the Company is affected by the general business conditions in this industry. Future adverse developments in the automotive industry could impact the Company’s liquidity position, lead to impairment charges and/or require additional restructuring of its operations.

10. Income Taxes

In calculating the provision for income taxes, the Company uses an estimate of the annual effective tax rate based upon the facts and circumstances known at each interim period. On a quarterly basis, the actual effective tax rate is adjusted, as appropriate, based upon changed facts and circumstances, if any, as compared to those forecasted at the beginning of the fiscal year and each interim period thereafter. For the three and six months ended March 31, 2015, the Company's effective tax rate for continuing operations was 22% and 20%, respectively. The effective rate was lower than the U.S. federal statutory rate of 35% primarily due to global tax planning and foreign tax rate differentials, partially offset by a tax rate change in Japan. For the three and six months ended March 31, 2014, the Company's effective tax rate for continuing operations was 19% for both periods. The effective rate was lower than the U.S. federal statutory rate of 35% primarily due to global tax planning and foreign tax rate differentials.

Valuation Allowance

The Company reviews the realizability of its deferred tax assets on a quarterly basis, or whenever events or changes in circumstances indicate that a review is required. In determining the requirement for a valuation allowance, the historical and projected financial results of the legal entity or consolidated group recording the net deferred tax asset are considered, along with any other positive or negative evidence. Since future financial results may differ from previous estimates, periodic adjustments to the Company’s valuation allowances may be necessary.

In the first quarter of fiscal 2014, the Company determined that it was more likely than not that a deferred tax asset associated with a capital loss in Mexico would not be utilized. Therefore, the Company recorded a $21 million valuation allowance as income tax expense.

Uncertain Tax Positions

At September 30, 2014, the Company had gross tax effected unrecognized tax benefits of $1,655 million, of which $1,505 million, if recognized, would impact the effective tax rate. Total net accrued interest at September 30, 2014 was approximately $106 million (net of tax benefit). The net change in interest and penalties during the six months ended March 31, 2015 and 2014 was not material. The Company recognizes interest and penalties related to unrecognized tax benefits as a component of income tax expense.

In the first quarter of fiscal 2015, the Company settled tax audits in multiple jurisdictions. The benefit of those settlements was substantially offset by a net tax provision recorded in the quarter where it was more likely than not that the losses would not be realized.

In the U.S., fiscal years 2010 through 2012 are currently under exam by the Internal Revenue Service (IRS) and 2007 through 2009 are currently under IRS appeals. Additionally, the Company is currently under exam in the following major foreign jurisdictions:

Tax Jurisdiction	Tax Years Covered
Belgium	2012 - 2014
Brazil	2004 - 2008, 2011 - 2012
Canada	2007 - 2012
France	2002 - 2013
Germany	2001 - 2012
Italy	2005 - 2009, 2011
Korea	2008 - 2012
Mexico	2003 - 2004, 2007 - 2013
Slovakia	2012
United Kingdom	2011 - 2012

It is reasonably possible that certain tax examinations, appellate proceedings and/or tax litigation will conclude within the next twelve months, the impact of which could be up to a $70 million benefit to tax expense.

Impacts of Tax Legislation

During the six months ended March 31, 2015, tax legislation was adopted in Japan which reduced its statutory income tax rate. As a result of the law change, the Company recorded income tax expense of $17 million. Tax legislation was also adopted in various other jurisdictions during the six month period ended March 31, 2015, and these changes did not have a material impact on the Company's consolidated financial statements.

The "look-through rule," under subpart F of the U.S. Internal Revenue Code, expired for the Company on September 30, 2014. The "look-through rule" had provided an exception to the U.S. taxation of certain income generated by foreign subsidiaries. The rule was extended in December 2014 retroactive to the beginning of the Company's 2015 fiscal year.

As a result of changes to Mexican tax law in the first quarter of fiscal 2014, the Company recorded a benefit to income tax expense of $25 million.

13. Earnings Per Share

The Company presents both basic and diluted earnings per share (EPS) amounts. Basic EPS is calculated by dividing net income attributable to Johnson Controls, Inc. by the weighted average number of common shares outstanding during the reporting period. Diluted EPS is calculated by dividing net income attributable to Johnson Controls, Inc. by the weighted average number of common shares and common equivalent shares outstanding during the reporting period that are calculated using the treasury stock method for stock options and unvested restricted stock. The treasury stock method assumes that the Company uses the proceeds from the exercise of stock option awards to repurchase common stock at the average market price during the period. The assumed proceeds under the treasury stock method include the purchase price that the grantee will pay in the future, compensation cost for future service that the Company has not yet recognized and any windfall tax benefits that would be credited to capital in excess of par value when the award generates a tax deduction. If there would be a shortfall resulting in a charge to capital in excess of par value, such an amount would be a reduction of the proceeds. For unvested restricted stock, assumed proceeds under the treasury stock method would include unamortized compensation cost and windfall tax benefits or shortfalls.

The following table reconciles the numerators and denominators used to calculate basic and diluted earnings per share (in millions):

	Three Months Ended March 31,					Six Months Ended March 31,
	2015		2014			2015		2014
Income Available to Common Shareholders
Income from continuing operations	$	452	$	410		$	933	$	843
Income (loss) from discontinued operations	77		(149		)	103		(113		)

The Company consolidates certain subsidiaries in which the noncontrolling interest party has within its control the right to require the Company to redeem all or a portion of its interest in the subsidiary. The redeemable noncontrolling interests are reported at their estimated redemption value. Any adjustment to the redemption value impacts retained earnings but does not impact net income. Redeemable noncontrolling interests which are redeemable only upon future events, the occurrence of which is not currently probable, are recorded at carrying value.

15. Derivative Instruments and Hedging Activities

The Company selectively uses derivative instruments to reduce market risk associated with changes in foreign currency, commodities, stock-based compensation liabilities and interest rates. Under Company policy, the use of derivatives is restricted to those intended for hedging purposes; the use of any derivative instrument for speculative purposes is strictly prohibited. A

description of each type of derivative utilized by the Company to manage risk is included in the following paragraphs. In addition, refer to Note 16, "Fair Value Measurements," of the notes to consolidated financial statements for information related to the fair value measurements and valuation methods utilized by the Company for each derivative type.

The Company has global operations and participates in the foreign exchange markets to minimize its risk of loss from fluctuations in foreign currency exchange rates. The Company primarily uses foreign currency exchange contracts to hedge certain of its foreign exchange rate exposures. The Company hedges 70% to 90% of the nominal amount of each of its known foreign exchange transactional exposures.

The Company has entered into cross-currency interest rate swaps to selectively hedge portions of its net investment in Japan. The currency effects of the cross-currency interest rate swaps are reflected in the accumulated other comprehensive income (AOCI) account within shareholders’ equity attributable to Johnson Controls, Inc. where they offset gains and losses recorded on the Company’s net investment in Japan. At March 31, 2015, September 30, 2014 and March 31, 2014 the Company had four cross-currency interest rate swaps outstanding totaling 20 billion yen.

The Company uses commodity contracts in the financial derivatives market in cases where commodity price risk cannot be naturally offset or hedged through supply base fixed price contracts. Commodity risks are systematically managed pursuant to policy guidelines. As cash flow hedges, the effective portion of the hedge gains or losses due to changes in fair value are initially recorded as a component of AOCI and are subsequently reclassified into earnings when the hedged transactions, typically sales, occur and affect earnings. Any ineffective portion of the hedge is reflected in the consolidated statements of income. The maturities of the commodity contracts coincide with the expected purchase of the commodities. The Company had the following outstanding commodity hedge contracts that hedge forecasted purchases:

		Volume Outstanding as of
Commodity	Units	March 31, 2015	September 30, 2014	March 31, 2014
Copper	Pounds	7,805,000	9,536,000	15,950,000
Lead	Metric Tons	10,952	5,200	—
Aluminum	Metric Tons	1,830	—	493
Tin	Metric Tons	1,000	2,070	957

The Company selectively uses equity swaps to reduce market risk associated with certain of its stock-based compensation plans, such as its deferred compensation plans. These equity compensation liabilities increase as the Company’s stock price increases and decrease as the Company’s stock price decreases. In contrast, the value of the swap agreement moves in the opposite direction of these liabilities, allowing the Company to fix a portion of the liabilities at a stated amount. As of March 31, 2015, September 30, 2014 and March 31, 2014, the Company had hedged approximately 4.1 million, 4.4 million and 4.6 million shares of its common stock, respectively.

The Company selectively uses interest rate swaps to reduce market risk associated with changes in interest rates for its fixed-rate bonds. As fair value hedges, the interest rate swaps and related debt balances are valued under a market approach using publicized swap curves. Changes in the fair value of the swap and hedged portion of the debt are recorded in the consolidated statements of income. In the second quarter of fiscal 2011, the Company entered into five fixed to floating interest rate swaps totaling $450 million to hedge the coupon of its 1.75% notes that matured in March 2014.

In the third quarter of fiscal 2014, the Company entered into four fixed to floating interest rate swaps totaling $400 million to hedge the coupon of its 2.6% notes maturing December 2016, three fixed to floating interest rate swaps totaling $300 million to hedge the coupon of its 1.4% notes maturing November 2017 and one fixed to floating interest rate swap totaling $150 million to hedge the coupon of its 7.125% coupon maturing July 2017.

In September 2005, the Company entered into three forward treasury lock agreements to reduce the market risk associated with changes in interest rates associated with the Company’s anticipated fixed-rate note issuance to finance the acquisition of York International (cash flow hedge). The three forward treasury lock agreements, which had a combined notional amount of $1.3 billion, fixed a portion of the future interest cost for 5-year, 10-year and 30-year notes. The fair value of each treasury lock agreement, or the difference between the treasury lock reference rate and the fixed rate at time of note issuance, is amortized to interest expense over the life of the respective note issuance. In January 2006, in connection with the Company’s debt refinancing, the three forward treasury lock agreements were terminated.

The following table presents the location and fair values of derivative instruments and hedging activities included in the Company’s consolidated statements of financial position (in millions):

The Company enters into International Swaps and Derivatives Associations (ISDA) master netting agreements with counterparties that permit the net settlement of amounts owed under the derivative contracts. The master netting agreements generally provide for net settlement of all outstanding contracts with a counterparty in the case of an event of default or a termination event. The Company has not elected to offset the fair value positions of the derivative contracts recorded in the consolidated statements of financial position. Collateral is generally not required of the Company or the counterparties under the master netting agreements. As of March 31, 2015, September 30, 2014 and March 31, 2014, no cash collateral was received or pledged under the master netting agreements.

The gross and net amounts of derivative assets and liabilities were as follows (in millions):

16. Fair Value Measurements

ASC 820, "Fair Value Measurement," defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 also establishes a three-level fair value hierarchy that prioritizes information used in developing assumptions when pricing an asset or liability as follows:

Level 1: Observable inputs such as quoted prices in active markets;

Level 2: Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and

Level 3: Unobservable inputs where there is little or no market data, which requires the reporting entity to develop its own assumptions.

ASC 820 requires the use of observable market data, when available, in making fair value measurements. When inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement.

Recurring Fair Value Measurements

The following tables present the Company’s fair value hierarchy for those assets and liabilities measured at fair value as of March 31, 2015, September 30, 2014 and March 31, 2014 (in millions):

Valuation Methods

Foreign currency exchange derivatives – The Company selectively hedges anticipated transactions that are subject to foreign exchange rate risk primarily using foreign currency exchange hedge contracts. The foreign currency exchange derivatives are valued under a market approach using publicized spot and forward prices. As cash flow hedges under ASC 815, "Derivatives and Hedging," the effective portion of the hedge gains or losses due to changes in fair value are initially recorded as a component of accumulated other comprehensive income and are subsequently reclassified into earnings when the hedged transactions occur and affect earnings. Any ineffective portion of the hedge is reflected in the consolidated statements of income. These contracts were highly effective in hedging the variability in future cash flows attributable to changes in currency exchange rates at March 31, 2015, September 30, 2014 and March 31, 2014. The fair value of foreign currency exchange derivatives not designated as hedging instruments under ASC 815 are recorded in the consolidated statements of income.

Commodity derivatives – The Company selectively hedges anticipated transactions that are subject to commodity price risk, primarily using commodity hedge contracts, to minimize overall price risk associated with the Company’s purchases of lead, copper, tin and aluminum. The commodity derivatives are valued under a market approach using publicized prices, where available, or dealer quotes. As cash flow hedges, the effective portion of the hedge gains or losses due to changes in fair value are initially recorded as a component of accumulated other comprehensive income and are subsequently reclassified into earnings when the hedged transactions, typically sales, occur and affect earnings. Any ineffective portion of the hedge is reflected in the consolidated statements of income. These contracts were highly effective in hedging the variability in future cash flows attributable to changes in commodity prices at March 31, 2015, September 30, 2014 and March 31, 2014.

Interest rate swaps and related debt – The Company selectively uses interest rate swaps to reduce market risk associated with changes in interest rates for its fixed-rate bonds. As fair value hedges, the interest rate swaps and related debt balances are valued under a market approach using publicized swap curves. Changes in the fair value of the swap and hedged portion of the debt are recorded in the consolidated statements of income. In the second quarter of fiscal 2011, the Company entered into five fixed to floating interest rate swaps totaling $450 million to hedge the coupon of its 1.75% notes that matured in March 2014. In the fourth quarter of fiscal 2013, the Company entered into one fixed to floating interest rate swap totaling approximately $125 million to hedge the coupon of its 7.7% notes that matured in March 2015 and four fixed to floating interest rate swaps totaling $800 million to hedge the coupon of its 5.5% notes maturing January 2016. In the third quarter of fiscal 2014, the Company entered into four fixed to floating interest rate swaps totaling $400 million to hedge the coupon of its 2.6% notes maturing December 2016, three fixed to floating interest rate swaps totaling $300 million to hedge the coupon of its 1.4% notes maturing November 2017 and one fixed to floating interest rate swap totaling $150 million to hedge the coupon of its 7.125% coupon maturing July 2017. There were twelve interest rate swaps outstanding as of March 31, 2015, thirteen interest rate swaps outstanding as of September 30, 2014 and five interest rate swaps outstanding as of March 31, 2014.

Cross-currency interest rate swaps – The Company selectively uses cross-currency interest rate swaps to hedge the foreign currency rate risk associated with certain of its investments in Japan. The cross-currency interest rate swaps are valued using observable market data. Changes in the market value of the swaps are reflected in the foreign currency translation adjustments component of accumulated other comprehensive income where they offset gains and losses recorded on the Company’s net investment in Japan. At March 31, 2015, September 30, 2014 and March 31, 2014, the Company had four cross-currency interest rate swaps outstanding totaling 20 billion yen.

Investments in marketable common stock – The Company invests in certain marketable common stock, which is valued under a market approach using publicized share prices. There were no unrealized gains or losses recorded in accumulated other comprehensive income on these investments as of March 31, 2015, September 30, 2014 and March 31, 2014. During the six months ended March 31, 2014, the Company sold certain marketable common stock for approximately $25 million. As a result, the Company recorded $8 million of realized gains within selling, general and administrative expenses in the Automotive Experience Seating segment.

Equity swaps – The Company selectively uses equity swaps to reduce market risk associated with certain of its stock-based compensation plans, such as its deferred compensation plans. The equity swaps are valued under a market approach as the fair value of the swaps is equal to the Company’s stock price at the reporting period date. Changes in fair value on the equity swaps are reflected in the consolidated statements of income within selling, general and administrative expenses.

The fair values of cash and cash equivalents, accounts receivable, short-term debt and accounts payable approximate their carrying values. The fair value of long-term debt, which was $6.8 billion, $6.8 billion and $5.2 billion at March 31, 2015, September 30, 2014 and March 31, 2014, respectively, was determined primarily using market quotes classified as Level 1 inputs within the ASC 820 fair value hierarchy.

17. Segment Information

At March 31, 2015, the Company determined that its GWS segment met the criteria to be classified as a discontinued operation, which required retrospective application to financial information for all periods presented. Refer to Note 4, "Discontinued Operations," of the notes to consolidated financial statements for further information regarding the Company's discontinued operations.

ASC 280, "Segment Reporting," establishes the standards for reporting information about segments in financial statements. In applying the criteria set forth in ASC 280, the Company has determined that it has six reportable segments for financial reporting purposes. The Company’s six reportable segments are presented in the context of its three primary businesses – Building Efficiency, Automotive Experience and Power Solutions.

Building Efficiency

Building Efficiency designs, produces, markets and installs heating, ventilating and air conditioning (HVAC) and control systems that monitor, automate and integrate critical building segment equipment and conditions including HVAC, fire-safety and security in commercial buildings and in various industrial applications.

• North America Systems and Service provides HVAC and controls systems, energy efficient solutions and technical services, including inspection, scheduled maintenance, and repair and replacement of mechanical and control systems to non-residential buildings and industrial applications in the North American marketplace.

• Asia provides HVAC and refrigeration systems and technical services to the Asian marketplace.

• Other provides HVAC and refrigeration systems and technical services to markets in Europe, the Middle East and Latin America. Other also designs and produces heating and air conditioning solutions for residential and light commercial applications, and markets products to the replacement and new construction markets.

Automotive Experience

Automotive Experience designs and manufactures interior systems and products for passenger cars and light trucks, including vans, pick-up trucks and sport utility/crossover vehicles.

• Seating produces automotive seat metal structures and mechanisms, foam, trim, fabric and complete seat systems.

• Interiors produces instrument panels, floor consoles and door panels.

Power Solutions

Power Solutions services both automotive original equipment manufacturers and the battery aftermarket by providing advanced battery technology, coupled with systems engineering, marketing and service expertise.

Management evaluates the performance of the segments based primarily on segment income, which represents income from continuing operations before income taxes and noncontrolling interests excluding net financing charges, significant restructuring and impairment costs, and net mark-to-market adjustments on pension and postretirement plans. General corporate and other overhead expenses are allocated to business segments in determining segment income. As mentioned above, the previously reported GWS segment met the criteria to be classified as a discontinued operation, and general corporate overhead was not allocated to discontinued operations. The Company reported discontinued operations through retrospective

18. Commitments and Contingencies

The Company accrues for potential environmental liabilities when it is probable a liability has been incurred and the amount of the liability is reasonably estimable. Reserves for environmental liabilities totaled $22 million, $24 million and $24 million at March 31, 2015, September 30, 2014 and March 31, 2014, respectively. The Company reviews the status of its environmental sites on a quarterly basis and adjusts its reserves accordingly. Such potential liabilities accrued by the Company do not take into consideration possible recoveries of future insurance proceeds. They do, however, take into account the likely share other

parties will bear at remediation sites. It is difficult to estimate the Company’s ultimate level of liability at many remediation sites due to the large number of other parties that may be involved, the complexity of determining the relative liability among those parties, the uncertainty as to the nature and scope of the investigations and remediation to be conducted, the uncertainty in the application of law and risk assessment, the various choices and costs associated with diverse technologies that may be used in corrective actions at the sites, and the often quite lengthy periods over which eventual remediation may occur. Nevertheless, the Company does not currently believe that any claims, penalties or costs in connection with known environmental matters will have a material adverse effect on the Company’s financial position, results of operations or cash flows. In addition, the Company has identified asset retirement obligations for environmental matters that are expected to be addressed at the retirement, disposal, removal or abandonment of existing owned facilities, primarily in the Power Solutions business. At March 31, 2015, September 30, 2014 and March 31, 2014, the Company recorded conditional asset retirement obligations of $64 million, $52 million and $58 million, respectively.

The Company is involved in various lawsuits, claims and proceedings incident to the operation of its businesses, including those pertaining to product liability, environmental, safety and health, intellectual property, employment, commercial and contractual matters, and various other casualty matters. Although the outcome of litigation cannot be predicted with certainty and some lawsuits, claims or proceedings may be disposed of unfavorably to us, it is management’s opinion that none of these will have a material adverse effect on the Company’s financial position, results of operations or cash flows. Costs related to such matters were not material to the periods presented.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders

of Johnson Controls, Inc.

We have reviewed the accompanying consolidated statements of financial position of Johnson Controls, Inc. and its subsidiaries as of March 31, 2015 and 2014, and the related consolidated statements of income, of comprehensive income (loss), and of cash flows for the three-month and six-month periods ended March 31, 2015 and 2014. These interim financial statements are the responsibility of the Company’s management.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to the accompanying consolidated interim financial statements for them to be in conformity with accounting principles generally accepted in the United States of America.

We previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated statement of financial position as of September 30, 2014 and the related consolidated statements of income, of shareholders’ equity, of comprehensive income (loss), and of cash flows for the year then ended (not presented herein), and in our report dated November 19, 2014 (which included an explanatory paragraph with respect to the exclusion of Air Distribution Technologies, Inc. in the assessment of internal controls over financial reporting), we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying consolidated statement of financial position as of September 30, 2014, is fairly stated in all material respects in relation to the consolidated statement of financial position from which it has been derived.

Report on Form 10-K for the year ended September 30, 2014. References in the following discussion and analysis to "Three Months" refer to the three months ended March 31, 2015 compared to the three months ended March 31, 2014, while references to "Year-to-Date" refer to the six months ended March 31, 2015 compared to the six months ended March 31, 2014.

At March 31, 2015, the Company determined that its Building Efficiency Global Workplace Solutions (GWS) segment met the criteria to be classified as a discontinued operation, which required retrospective application to financial information for all periods presented. Refer to Note 4, "Discontinued Operations," of the notes to consolidated financial statements for further information regarding the Company's discontinued operations.

Outlook

On April 23, 2015, the Company announced that it is providing updated guidance now that the GWS business is being reported as a discontinued operation. Previously, the Company provided full year earnings guidance of $3.55 - $3.70 per diluted share, including the GWS contribution of approximately $0.20 per diluted share. With GWS reported as a discontinued operation, the Company updated its full year earnings guidance from continuing operations to $3.30 - $3.45 per diluted share. The updated guidance assumes a euro / dollar conversion at $1.05 and improved operating efficiencies. The Company also reaffirmed its full fiscal year guidance for segment margin improvements in all three of its businesses. For the third quarter of fiscal 2015, the Company provided earnings guidance from continuing operations of $0.90 to $0.92 per diluted share.

In April 2015, the Company signed an agreement formally establishing the previously announced automotive interiors joint venture with Yanfeng Automotive Trim Systems. The formation of the joint venture is expected to close in the fourth quarter of fiscal 2015, pending regulatory approvals.

In March 2015, the Company signed a definitive agreement to sell its GWS business to CBRE Group, Inc. for $1.475 billion. The transaction is expected to close near the end of fiscal 2015, pending regulatory approvals.

In January 2015, the Company signed a definitive agreement to create a joint venture with Hitachi to expand its Building Efficiency product offerings. The formation of the joint venture is expected to close near the end of fiscal 2015, pending regulatory approvals.

Liquidity and Capital Resources

The Company believes its capital resources and liquidity position at March 31, 2015 are adequate to meet projected needs. The Company believes requirements for working capital, capital expenditures, dividends, share repurchases, minimum pension contributions, debt maturities and any potential acquisitions during the remainder of fiscal 2015 will be funded from operations, supplemented by short- and long-term borrowings, if required. The Company currently manages its short-term debt position in the U.S. and euro commercial paper markets and bank loan markets. The Company continues to adjust its commercial paper maturities and issuance levels given market reactions to industry events and changes in the Company’s credit rating. In the event the Company is unable to issue commercial paper, it would have the ability to draw on its $2.5 billion revolving credit facility, which matures in August 2018. There were no draws on the revolving credit facility as of March 31, 2015. As such, the Company believes it has sufficient financial resources to fund operations and meet its obligations for the foreseeable future.

The Company’s debt financial covenants require a minimum consolidated shareholders’ equity attributable to Johnson Controls, Inc. of at least $3.5 billion at all times and allow a maximum aggregated amount of 10% of consolidated shareholders’ equity attributable to Johnson Controls, Inc. for liens and pledges. For purposes of calculating the Company’s covenants, consolidated shareholders’ equity attributable to Johnson Controls, Inc. is calculated without giving effect to (i) the application of Accounting Standards Codification (ASC) 715-60, "Defined Benefit Plans - Other Postretirement," or (ii) the cumulative foreign currency translation adjustment. As of March 31, 2015, consolidated shareholders’ equity attributable to Johnson Controls, Inc. as defined in the Company’s debt financial covenants was $11.7 billion and there was a maximum of $236 million of liens outstanding. The Company expects to remain in compliance with all covenants and other requirements set forth in its credit agreements and indentures for the foreseeable future. None of the Company’s debt agreements limit access to stated borrowing levels or require accelerated repayment in the event of a decrease in the Company’s credit rating.

The key financial assumptions used in calculating the Company’s pension liability are determined annually, or whenever plan assets and liabilities are re-measured as required under accounting principles generally accepted in the U.S., including the expected rate of return on its plan assets. In fiscal 2015, the Company believes the long-term rate of return will approximate 7.50%, 4.40% and 5.75% for U.S. pension, non-U.S. pension and postretirement plans, respectively. As a result of the updated U.S. mortality tables and mortality improvement scales by the Society of Actuaries, the mortality assumptions expected to be used to calculate

39

the Company’s U.S. pension and postretirement liabilities at the end of fiscal 2015 are estimated to result in a mark-to-market charge in the fourth quarter of fiscal 2015 ranging from $150 million to $200 million. During the first six months of fiscal 2015, the Company made approximately $52 million in total pension contributions. In total, the Company expects to contribute approximately $64 million in cash to its defined benefit pension plans in fiscal 2015. The Company does not expect to make any significant contributions to its postretirement plans in fiscal 2015.

To better align its resources with its growth strategies and reduce the cost structure of its global operations to address the softness in certain underlying markets, the Company committed to significant restructuring plans in fiscal 2014, 2013 and 2012 and recorded $324 million, $903 million and $271 million, respectively, of restructuring and impairment costs in the consolidated statements of income within continuing operations. The restructuring actions related to cost reduction initiatives in the Company’s Automotive Experience, Building Efficiency and Power Solutions businesses and included workforce reductions, plant closures, and asset and goodwill impairments. The Company currently estimates that upon completion of the restructuring actions, the fiscal 2014, 2013 and 2012 restructuring plans will reduce annual operating costs from continuing operations by approximately $175 million, $350 million and $265 million, respectively, which is primarily the result of lower cost of sales due to reduced employee-related costs and lower depreciation and amortization expense. The Company expects a portion of these savings, net of execution costs, will be achieved over the next year and the full annual benefit of these actions is expected in fiscal 2016. For fiscal 2015, the savings from continuing operations, net of execution costs, are expected to approximate 85% of the expected annual operating cost reduction. The restructuring actions are expected to be substantially complete by the end of fiscal 2015. The respective year’s restructuring plan reserve balances of $128 million, $95 million and $20 million, respectively, at March 31, 2015 are expected to be paid in cash.

Income Tax Provision

	Three Months Ended March 31,								Six Months Ended March 31,
(in millions)	2015			2014			Change		2015			2014			Change
Income tax provision	$	132		$	101		31	%	$	250		$	204		23	%
Effective tax rate	22		%	19		%			20		%	19		%

In calculating the provision for income taxes, the Company uses an estimate of the annual effective tax rate based upon the facts and circumstances known at each interim period. On a quarterly basis, the annual effective tax rate is adjusted, as appropriate, based upon changed facts and circumstances, if any, as compared to those forecasted at the beginning of the fiscal year and each interim period thereafter.

For the three months and six months ended March 31, 2015, the Company's effective tax rate for continuing operations was 22% and 20%, respectively. The effective rate was lower than the U.S. federal statutory rate of 35% primarily due to global tax planning and foreign tax rate differentials partially offset by a tax rate change in Japan. For the three and six months ended March 31, 2014, the Company's effective tax rate for continuing operations was 19% for both periods. The effective rate was lower than the U.S. federal statutory rate of 35% primarily due to global tax planning and foreign tax rate differentials.

During the six months ended March 31, 2015, tax legislation was adopted in Japan which reduced its statutory income tax rate. As a result of the law change, the Company recorded income tax expense of $17 million.

In the first quarter of fiscal 2015, the Company settled tax audits in multiple jurisdictions. The benefit of those settlements was substantially offset by a net tax provision recorded in the quarter where it was more likely than not that the losses would not be realized.

In the first quarter of fiscal 2014, the Company determined that it was more likely than not that a deferred tax asset associated with a capital loss in Mexico would not be utilized. Therefore, the Company recorded a $21 million valuation allowance as income tax expense.

As a result of changes to Mexican tax law in the first quarter of fiscal 2014, the Company recorded a benefit to income tax expense of $25 million.

• Net sales increased due to higher sales volumes ($187 million), favorable pricing and product mix ($71 million), and the impact of higher lead costs on pricing ($16 million), partially offset by the unfavorable impact of foreign currency translation ($178 million).

• Segment income increased due to higher volumes ($58 million), lower operating costs ($19 million), and favorable pricing and product mix including lead acquisition costs ($7 million), partially offset by the unfavorable impact of foreign currency translation ($19 million), a prior year gain on acquisition of a partially-owned affiliate ($19 million), lower equity income ($5 million), and higher selling, general and administrative expenses ($2 million).

Backlog

Building Efficiency’s backlog relates to its control systems and service activity. At March 31, 2015, the unearned backlog was $4.6 billion, or a 4% decrease compared to March 31, 2014. Adjusted for foreign currency, backlog levels were consistent with the second quarter of last year. The Other and Asia segment backlogs decreased compared to prior year levels.

Accounts payable	4,640			5,270			-12	%	6,042			-23	%

• The Company defines working capital as current assets less current liabilities, excluding cash, short-term debt, the current portion of long-term debt, and the current portion of assets and liabilities held for sale. Management believes that this measure of working capital, which excludes financing-related items, provides a more useful measurement of the Company’s operating performance.

• The increase in working capital at March 31, 2015 as compared to September 30, 2014, excluding the impact of amounts classified as held for sale, was primarily due to a decrease in accounts payable due to changes in foreign exchange rates and timing of supplier payments, lower accrued compensation and benefits primarily due to timing of incentive compensation payments and lower restructuring reserves due to utilization of restructuring reserves, partially offset by lower accounts receivable due to changes in foreign exchange rates and timing of customer receipts. Compared to March 31, 2014, excluding the impact of amounts classified as held for sale, the slight increase was primarily due to a decrease in accounts payable due to changes in foreign exchange rates and timing of supplier payments, and higher inventory due to higher production levels, partially offset by lower accounts receivable due to changes in foreign exchange rates and timing of customer receipts.

• The Company’s days sales in accounts receivable at March 31, 2015 were 55, higher than 54 and 52 at the comparable period ended September 30, 2014 and March 31, 2014, respectively. There have been no significant adverse changes in the level of overdue receivables or changes in revenue recognition methods.

• The Company’s inventory turns for the three months ended March 31, 2015 were slightly higher than the comparable period ended September 30, 2014 primarily due to lower inventory production. Inventory turns were lower than the comparable period ended March 31, 2014 primarily due to higher inventory production.

• Days in accounts payable at March 31, 2015 were 67 days, lower than 74 and 69 at the comparable periods ended September 30, 2014 and March 31, 2014, respectively.

Cash Flows

	Three Months Ended March 31,						Six Months Ended March 31,
(in millions)	2015			2014			2015			2014

Cash used by investing activities	(200		)	(222		)	(454		)	(653		)
Cash (used) provided by financing activities	(222		)	(526		)	7			(604		)
Capital expenditures	(294		)	(257		)	(556		)	(602		)

• The decrease in cash provided by operating activities for the three and six months ended March 31, 2015 was primarily due to income tax payments and unfavorable changes in accrued liabilities. The operating cash flow impact from discontinued operations was not significant in any period presented.

• The decrease in cash used by investing activities for the three months ended March 31, 2015 was primarily due to cash received from a business divestiture, partially offset by higher capital expenditures and changes in long-term investments. The decrease in cash used by investing activities for the six months ended March 31, 2015 was primarily due to cash received from a business divestiture, cash paid for business acquisitions in the prior year and lower capital expenditures, partially offset by changes in long-term investments.

• The decrease in cash used by financing activities for the three months ended March 31, 2015 was primarily due to higher repayments of debt in the prior year, partially offset by higher stock repurchases. The increase in cash provided by financing activities for the six months ended March 31, 2015 was primarily due to higher repayments of debt in the prior year and higher stock repurchases in the prior year, partially offset by an increase in long-term debt in the prior year.

• The increase in capital expenditures for the three months ended March 31, 2015 primarily relates to the on-going implementation of a new enterprise resource planning system. The decrease in capital expenditures for the six months ended March 31, 2015 primarily relates to prior year capacity increases and vertical integration efforts in the Power Solutions business, partially offset by the on-going implementation of a new enterprise resource planning system.

Deferred Taxes

The Company reviews the realizability of its deferred tax assets on a quarterly basis, or whenever events or changes in circumstances indicate that a review is required. In determining the requirement for a valuation allowance, the historical and projected financial results of the legal entity or consolidated group recording the net deferred tax asset are considered, along with any other positive or negative evidence. Since future financial results may differ from previous estimates, periodic adjustments to the Company’s valuation allowances may be necessary.

The Company has certain subsidiaries, mainly located in Brazil, France, Germany and Spain, which have generated operating and/or capital losses and, in certain circumstances, have limited loss carryforward periods. In accordance with ASC 740, "Income Taxes," the Company is required to record a valuation allowance when it is more likely than not the Company will not utilize deductible amounts or net operating losses for each legal entity or consolidated group based on the tax rules in the applicable jurisdiction, evaluating both positive and negative historical evidences as well as expected future events and tax planning strategies.

In the first quarter of fiscal 2014, the Company determined that it was more likely than not that a deferred tax asset associated with a capital loss in Mexico would not be utilized. Therefore, the Company recorded a $21 million valuation allowance as income tax expense.

Capitalization

(in millions)	March 31, 2015			September 30, 2014			Change		March 31, 2014			Change
Short-term debt	$	1,321		$	183				$	1,375
Current portion of long-term debt	815			140					143
Long-term debt	5,448			6,357					4,733
Total debt	7,584			6,680			14	%	6,251			21	%
Shareholders’ equity attributable to Johnson Controls, Inc.	10,583			11,311			-6	%	11,686			-9	%
Total capitalization	$	18,167		$	17,991		1	%	$	17,937		1	%
Total debt as a % of total capitalization	42		%	37		%			35		%

• The Company believes the percentage of total debt to total capitalization is useful to understanding the Company’s financial condition as it provides a review of the extent to which the Company relies on external debt financing for its funding and is a measure of risk to its shareholders.

• At March 31, 2015, the Company had committed bilateral euro denominated revolving credit facilities totaling 237 million euro. Additionally, at March 31, 2015, the Company had committed bilateral U.S. dollar denominated revolving credit facilities totaling $135 million. As of March 31, 2015, facilities in the amount of 237 million euro are scheduled to expire in fiscal 2015 and facilities in the amount of $135 million are scheduled to expire in fiscal 2016. There were no draws on any of these revolving facilities as of March 31, 2015.

• In March 2015, the Company retired $125 million in principal amount, plus accrued interest, of its 7.7% fixed rate notes that matured in March 2015.

• In February 2015, the Company entered into a seven-month, $150 million, floating rate term loan scheduled to mature in September 2015. Proceeds from the term loan were used for general corporate purposes.

• In January 2015, the Company entered into a one-year, $90 million, committed revolving credit facility scheduled to mature in January 2016. The Company drew on the full credit facility during the quarter ended March 31, 2015. Proceeds from the revolving credit facility were used for general corporate purposes.

• In December 2014, the Company entered into a nine-month, $500 million, floating rate term loan scheduled to mature in September 2015. Proceeds from the term loan were used for general corporate purposes.

• In December 2014, the Company entered into a nine-month, $100 million, floating rate term loan scheduled to mature in September 2015. Proceeds from the term loan were used for general corporate purposes.

• In June 2014, the Company issued $300 million aggregate principal amount of 1.4% senior unsecured fixed rate notes due in fiscal 2018, $500 million aggregate principal amount of 3.625% senior unsecured fixed rate notes due in fiscal 2024, $450 million aggregate principal amount of 4.625% senior unsecured fixed rate notes due in fiscal 2044 and $450 million aggregate principal amount of 4.95% senior unsecured fixed rate notes due in fiscal 2064. Aggregate net proceeds of $1.7 billion from the issuances were used to finance the acquisition of ADT and for other general corporate purposes.

• In March 2014, the Company entered into a nine-month, $150 million, floating rate term loan that matured in December 2014. Proceeds from the term loan were used for general corporate purposes. The loan was repaid during the quarter ended June 30, 2014.

• In March 2014, the Company retired $450 million in principal amount, plus accrued interest, of its 1.75% fixed rate notes that matured in March 2014.

50

• In February 2014, the Company retired $350 million in principal amount, plus accrued interest, of its floating rate notes that matured in February 2014.

• In January 2014, the Company entered into a one-year, $150 million, floating rate term loan that matured in January 2015. Proceeds from the term loan were used for general corporate purposes. The loan was repaid in the quarter ended September 30, 2014.

• In December 2013, the Company entered into a five-year, 220 million euro, floating rate credit facility scheduled to mature in fiscal 2019. The Company drew on the full credit facility during the quarter ended December 31, 2013. Proceeds from the facility were used for general corporate purposes.

• In December 2013, the Company entered into a nine-month, $500 million, floating rate term loan that matured in September 2014. Proceeds from the term loan were used for general corporate purposes. The loan was repaid in the quarter ending September 30, 2014.

• The Company also selectively makes use of short-term credit lines. The Company estimates that, as of March 31, 2015, it could borrow up to $1.3 billion based on average borrowing levels during the quarter on committed credit lines.

• The Company believes its capital resources and liquidity position at March 31, 2015 are adequate to meet projected needs. The Company believes requirements for working capital, capital expenditures, dividends, stock repurchases, minimum pension contributions, debt maturities and any potential acquisitions in the remainder of fiscal 2015 will continue to be funded from operations, supplemented by short- and long-term borrowings, if required. The Company currently manages its short-term debt position in the U.S. and euro commercial paper markets and bank loan markets. In the event the Company is unable to issue commercial paper, it would have the ability to draw on its $2.5 billion revolving credit facility, which matures in August 2018. There were no draws on the revolving credit facility as of March 31, 2015. As such, the Company believes it has sufficient financial resources to fund operations and meet its obligations for the foreseeable future.

• The Company earns a significant amount of its operating income outside the U.S., which is deemed to be permanently reinvested in foreign jurisdictions. The Company currently does not intend nor foresee a need to repatriate these funds. The Company’s intent is for such earnings to be reinvested by the subsidiaries or to be repatriated only when it would be tax effective through the utilization of foreign tax credits. However, the Company did provide incremental income tax expense on the undistributed earnings of certain non-U.S. subsidiaries that have assets held for sale or are themselves held for sale at March 31, 2015. The Company expects existing domestic cash and liquidity to continue to be sufficient to fund the Company’s domestic operating activities and cash commitments for investing and financing activities for at least the next twelve months and thereafter for the foreseeable future. In addition, the Company expects existing foreign cash, cash equivalents, short-term investments and cash flows from operations to continue to be sufficient to fund the Company’s foreign operating activities and cash commitments for investing activities, such as material capital expenditures, for at least the next twelve months and thereafter for the foreseeable future. Should the Company require more capital in the U.S. than is generated by operations domestically, the Company could elect to raise capital in the U.S. through debt or equity issuances. This alternative could result in increased interest expense or other dilution of the Company’s earnings. The Company has borrowed funds domestically and continues to have the ability to borrow funds domestically at reasonable interest rates.

• The Company’s debt financial covenants require a minimum consolidated shareholders’ equity attributable to Johnson Controls, Inc. of at least $3.5 billion at all times and allow a maximum aggregated amount of 10% of consolidated shareholders’ equity attributable to Johnson Controls, Inc. for liens and pledges. For purposes of calculating the Company’s covenants, consolidated shareholders’ equity attributable to Johnson Controls, Inc. is calculated without giving effect to (i) the application of ASC 715-60, "Defined Benefit Plans - Other Postretirement," or (ii) the cumulative foreign currency translation adjustment. As of March 31, 2015, consolidated shareholders’ equity attributable to Johnson Controls, Inc. as defined per the Company’s debt financial covenants was $11.7 billion and there was a maximum of $236 million of liens outstanding. The Company expects to remain in compliance with all covenants and other requirements set forth in its credit agreements and indentures for the foreseeable future. None of the Company’s debt agreements limit access to stated borrowing levels or require accelerated repayment in the event of a decrease in the Company’s credit rating.

New Accounting Standards

In April 2015, the FASB issued Accounting Standards Update (ASU) No. 2015-03, "Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs." ASU No. 2015-03 requires that debt issuance costs related to a

51

recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the debt liability. ASU No. 2015-03 will be effective retrospectively for the Company for the quarter ending December 31, 2016, with early adoption permitted. The adoption of this guidance is not expected to have a significant impact on the Company's consolidated financial statements.

In February 2015, the FASB issued ASU No. 2015-02, "Consolidation (Topic 810): Amendments to the Consolidation Analysis." ASU No. 2015-02 amends the analysis performed to determine whether a reporting entity should consolidate certain types of legal entities. ASU No. 2015-02 will be effective retrospectively for the Company for the quarter ending December 31, 2016, with early adoption permitted. The Company is currently assessing the impact adoption of this guidance will have on its consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)." ASU No. 2014-09 clarifies the principles for recognizing revenue when an entity either enters into a contract with customers to transfer goods or services or enters into a contract for the transfer of non-financial assets. The original standard will be effective retrospectively for the Company for the quarter ending December 31, 2017; however in April 2015, the FASB proposed a one-year deferral of the standard. If the deferral is approved, the new standard will become effective retrospectively for the Company for the quarter ending December 31, 2018, with early adoption permitted, but not before the original effective date. The Company is currently assessing the impact adoption of this guidance will have on its consolidated financial statements.

In April 2014, the FASB issued ASU No. 2014-08, "Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity." ASU No. 2014-08 limits discontinued operations reporting to situations where the disposal represents a strategic shift that has (or will have) a major effect on an entity's operations and financial results, and requires expanded disclosures for discontinued operations. ASU No. 2014-08 will be effective prospectively for the Company for disposals that occur during or after the quarter ending December 31, 2015, with early adoption permitted in certain instances. The significance of this guidance for the Company is dependent on any future dispositions or disposals.

In July 2013, the FASB issued ASU No. 2013-11, "Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists." ASU No. 2013-11 clarifies that companies should present an unrecognized tax benefit as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward. ASU No. 2013-11 was effective for the Company for the quarter ending December 31, 2014. The adoption of this guidance did not have a significant impact on the Company's consolidated financial statements.

PwC has, however, applied limited review procedures in accordance with professional standards for reviews of interim financial information. Accordingly, you should restrict your reliance on their reports on such information. PwC is not subject to the liability provisions of Section 11 of the Securities Act of 1933 for its reports on the interim financial information because such reports do not constitute "reports" or "parts" of the registration statements prepared or certified by PwC within the meaning of Sections 7 and 11 of the Securities Act of 1933.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

As of March 31, 2015, the Company had not experienced any adverse changes in market risk exposures that materially affected the quantitative and qualitative disclosures presented in the Company's Annual Report on Form 10-K for the year ended September 30, 2014.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of our disclosure controls and procedures, as such term is defined under Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended (Exchange Act). Based upon their evaluation of these disclosure controls and procedures, the principal executive officer and principal financial officer concluded that the disclosure controls and procedures were effective as of March 31, 2015 to ensure that information required to be disclosed by the Company

52

in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time period specified in the SEC’s rules and forms, and to ensure that information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including its principal executive and principal financial officers, as appropriate, to allow timely decisions regarding disclosure.

Changes in Internal Control Over Financial Reporting

There have been no significant changes in the Company’s internal control over financial reporting during the three months ended March 31, 2015 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

The Company is undertaking the implementation of new enterprise resource planning (ERP) systems, which will occur over a period of several years. As the phased roll-out of the new ERP systems occurs, the Company may experience changes in internal control over financial reporting. No significant changes were made to the Company’s current internal control over financial reporting as a result of the implementation of the new ERP systems during the three and six months ended March 31, 2015.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

As noted in Item 1 to the Company’s Annual Report on Form 10-K for the year ended September 30, 2014, liabilities potentially arise globally under various environmental laws and worker safety laws for activities that are not in compliance with such laws and for the cleanup of sites where Company-related substances have been released into the environment.

Currently, the Company is responding to allegations that it is responsible for performing environmental remediation, or for the repayment of costs spent by governmental entities or others performing remediation, at approximately 40 sites in the United States. Many of these sites are landfills used by the Company in the past for the disposal of waste materials; others are secondary lead smelters and lead recycling sites where the Company returned lead-containing materials for recycling; a few involve the cleanup of Company manufacturing facilities; and the remaining fall into miscellaneous categories. The Company may face similar claims of liability at additional sites in the future. Where potential liabilities are alleged, the Company pursues a course of action intended to mitigate them.

The Company accrues for potential environmental liabilities in a manner consistent with accounting principles generally accepted in the United States; that is, when it is probable a liability has been incurred and the amount of the liability is reasonably estimable. Reserves for environmental liabilities totaled $22 million, $24 million and $24 million at March 31, 2015, September 30, 2014 and March 31, 2014, respectively. The Company reviews the status of its environmental sites on a quarterly basis and adjusts its reserves accordingly. Such potential liabilities accrued by the Company do not take into consideration possible recoveries of future insurance proceeds. They do, however, take into account the likely share other parties will bear at remediation sites. It is difficult to estimate the Company’s ultimate level of liability at many remediation sites due to the large number of other parties that may be involved, the complexity of determining the relative liability among those parties, the uncertainty as to the nature and scope of the investigations and remediation to be conducted, the uncertainty in the application of law and risk assessment, the various choices and costs associated with diverse technologies that may be used in corrective actions at the sites, and the often quite lengthy periods over which eventual remediation may occur. Nevertheless, the Company does not currently believe that any claims, penalties or costs in connection with known environmental matters will have a material adverse effect on the Company’s financial position, results of operations or cash flows. In addition, the Company has identified asset retirement obligations for environmental matters that are expected to be addressed at the retirement, disposal, removal or abandonment of existing owned facilities, primarily in the Power Solutions business. At March 31, 2015, September 30, 2014 and March 31, 2014, the Company recorded conditional asset retirement obligations of $64 million, $52 million and $58 million, respectively.

In June 2013, the Company self-reported to the Securities and Exchange Commission (SEC) and the Department of Justice (DOJ) alleged Foreign Corrupt Practices Act (FCPA) violations related to its Building Efficiency marine business in China dating back to 2007. These allegations were isolated to the Company’s marine business in China which had annual sales ranging from $20 million to $50 million during this period. The Company, under the oversight of its Audit Committee and Board of Directors, proactively initiated an investigation into this matter with the assistance of external legal counsel and external forensic accountants. In connection with this investigation, the Company has made and continues to evaluate certain enhancements to its FCPA compliance program. The Company continues to fully cooperate with the SEC and the DOJ; however, at this time, the Company is unable to predict the ultimate resolution of this matter with these agencies.

53

The Company is involved in various lawsuits, claims and proceedings incident to the operation of its businesses, including those pertaining to product liability, environmental, safety and health, intellectual property, employment, commercial and contractual matters, and various other casualty matters. Although the outcome of litigation cannot be predicted with certainty and some lawsuits, claims or proceedings may be disposed of unfavorably to us, it is management’s opinion that none of these will have a material adverse effect on the Company’s financial position, results of operations or cash flows. Costs related to such matters were not material to the periods presented.

ITEM 1A. RISK FACTORS

There have been no material changes to the disclosure regarding risk factors presented in Item 1A to the Company’s Annual Report on Form 10-K for the year ended September 30, 2014.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

In November 2012, the Company’s Board of Directors authorized a stock repurchase program to acquire up to $500 million of the Company’s outstanding common stock, which supersedes any prior programs. In September 2013, the Company’s Board of Directors authorized up to an additional $500 million in stock repurchases of the Company’s outstanding common stock, and in November 2013, the Company's Board of Directors authorized an additional $3.0 billion under the stock repurchase program, both incremental to prior authorizations. Stock repurchases under the stock repurchase program may be made through open market, privately negotiated, or structured transactions or otherwise at times and in such amounts as Company management deems appropriate. The stock repurchase program does not have an expiration date and may be amended or terminated by the Board of Directors at any time without prior notice. The Company spent approximately $1,249 million on repurchases under the stock repurchase program in fiscal 2014. As of March 31, 2015, the Company has spent approximately $810 million on repurchases under the stock repurchase program in fiscal 2015.

The Company entered into an Equity Swap Agreement, dated March 13, 2009, with Citibank, N.A. (Citibank). The Company selectively uses equity swaps to reduce market risk associated with its stock-based compensation plans, such as its deferred compensation plans. These equity compensation liabilities increase as the Company’s stock price increases and decrease as the Company’s stock price decreases. In contrast, the value of the Equity Swap Agreement moves in the opposite direction of these liabilities, allowing the Company to fix a portion of the liabilities at a stated amount.

In connection with the Equity Swap Agreement, Citibank may purchase unlimited shares of the Company’s stock in the market or in privately negotiated transactions. The Company disclaims that Citibank is an "affiliated purchaser" of the Company as such term is defined in Rule 10b-18(a)(3) under the Securities Exchange Act or that Citibank is purchasing any shares for the Company. The Equity Swap Agreement has no stated expiration date. The net effect of the change in fair value of the Equity Swap Agreement and the change in equity compensation liabilities was not material to the Company’s earnings for the three months ended March 31, 2015.

The following table presents information regarding the repurchase of the Company’s common stock by the Company as part of the publicly announced program and purchases of the Company’s common stock by Citibank in connection with the Equity Swap Agreement during the three months ended March 31, 2015.

The adjustment was made as a result of a true-up to the purchase price in the amount of $4 million, all of which was paid in the six months ended March 31, 2015. Also, in connection with this acquisition, the Company recorded additional goodwill of $21 million in fiscal 2015 related to the purchase price allocations. In fiscal 2014, the Company recorded goodwill of $837 million in the Building Efficiency Other segment as a result of the ADT acquisition. The purchase price allocations may be subsequently adjusted to reflect final valuation studies.

In January 2015, the Company signed a definitive agreement to create a joint venture with Hitachi to expand its Building Efficiency product offerings. The formation of the joint venture is expected to close near the end of fiscal 2015, pending regulatory approvals.

On March 31, 2015, the Company announced that it had reached a definitive agreement to sell its GWS business to CBRE Group Inc., subject to regulatory and other approvals. Estimated proceeds are expected to be $1.475 billion and the sale is expected to close near the end of fiscal 2015. At March 31, 2015, the Company determined that the GWS segment met the criteria to be classified as a discontinued operation. Refer to Note 4, "Discontinued Operations," of the notes to the consolidated financial statements for further disclosure related to the Company's discontinued operations.

In the three months ended March 31, 2015, the Company completed the sale of its interests in two GWS joint ventures to Brookfield Asset Management, Inc. The selling price, net of cash divested, was $141 million, all of which was received as of March 31, 2015. In connection with the sale, the Company recorded a $200 million gain, $127 million net of tax, within income from discontinued operations, net of tax on the consolidated statements of income and reduced goodwill in assets held for sale by $20 million.

In the first six months of fiscal 2014, the Company completed two acquisitions for a combined purchase price, net of cash acquired, of $128 million, all of which was paid in the six months ended March 31, 2014. The acquisitions in the aggregate were not material to the Company's consolidated financial statements. In connection with the acquisitions, the Company recorded goodwill of $100 million. As a result of one of the acquisitions, which increased the Company's ownership from a noncontrolling to controlling interest, the Company recorded a non-cash gain of $19 million in equity income for the Power Solutions business to adjust the Company's existing equity investment in the partially-owned affiliate to fair value.

In the first six months of fiscal 2014, the Company completed one divestiture for a sales price of $13 million, all of which was received as of March 31, 2014. The divestiture was not material to the Company’s consolidated financial statements. In connection with the divestiture, the Company recorded a gain, net of transaction costs, of $9 million in the Automotive Experience Interiors segment. There was no change in goodwill as a result of this transaction.

In the first six months of fiscal 2014, the Company adjusted the purchase price allocation of certain fiscal 2013 acquisitions and recorded additional goodwill of $2 million.

New Accounting Standards

New Accounting Standards

In April 2015, the FASB issued Accounting Standards Update (ASU) No. 2015-03, "Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs." ASU No. 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the debt liability. ASU No. 2015-03 will be effective retrospectively for the Company for the quarter ending December 31, 2016, with early adoption permitted. The adoption of this guidance is not expected to have a significant impact on the Company's consolidated financial statements.

In February 2015, the FASB issued ASU No. 2015-02, "Consolidation (Topic 810): Amendments to the Consolidation Analysis." ASU No. 2015-02 amends the analysis performed to determine whether a reporting entity should consolidate certain types of legal entities. ASU No. 2015-02 will be effective retrospectively for the Company for the quarter ending December 31, 2016, with early adoption permitted. The Company is currently assessing the impact adoption of this guidance will have on its consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)." ASU No. 2014-09 clarifies the principles for recognizing revenue when an entity either enters into a contract with customers to transfer goods or services or enters into a contract for the transfer of non-financial assets. The original standard will be effective retrospectively for the Company for the quarter ending December 31, 2017; however in April 2015, the FASB proposed a one-year deferral of the standard. If the deferral is approved, the new standard will become effective retrospectively for the Company for the quarter ending December 31, 2018, with early adoption permitted, but not before the original effective date. The Company is currently assessing the impact adoption of this guidance will have on its consolidated financial statements.

In April 2014, the FASB issued ASU No. 2014-08, "Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity." ASU No. 2014-08 limits discontinued operations reporting to situations where the disposal represents a strategic shift that has (or will have) a major effect on an entity's operations and financial results, and requires expanded disclosures for discontinued operations. ASU No. 2014-08 will be effective prospectively for the Company for disposals that occur during or after the quarter ending December 31, 2015, with early adoption permitted in certain instances. The significance of this guidance for the Company is dependent on any future dispositions or disposals.

In July 2013, the FASB issued ASU No. 2013-11, "Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists." ASU No. 2013-11 clarifies that companies should present an unrecognized tax benefit as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward. ASU No. 2013-11 was effective for the Company for the quarter ending December 31, 2014. The adoption of this guidance did not have a significant impact on the Company's consolidated financial statements.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

ASC 820, "Fair Value Measurement," defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 also establishes a three-level fair value hierarchy that prioritizes information used in developing assumptions when pricing an asset or liability as follows:

Level 1: Observable inputs such as quoted prices in active markets;

Level 2: Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and

Level 3: Unobservable inputs where there is little or no market data, which requires the reporting entity to develop its own assumptions.

ASC 820 requires the use of observable market data, when available, in making fair value measurements. When inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement.

Recurring Fair Value Measurements

The following tables present the Company’s fair value hierarchy for those assets and liabilities measured at fair value as of March 31, 2015, September 30, 2014 and March 31, 2014 (in millions):

Valuation Methods

Foreign currency exchange derivatives – The Company selectively hedges anticipated transactions that are subject to foreign exchange rate risk primarily using foreign currency exchange hedge contracts. The foreign currency exchange derivatives are valued under a market approach using publicized spot and forward prices. As cash flow hedges under ASC 815, "Derivatives and Hedging," the effective portion of the hedge gains or losses due to changes in fair value are initially recorded as a component of accumulated other comprehensive income and are subsequently reclassified into earnings when the hedged transactions occur and affect earnings. Any ineffective portion of the hedge is reflected in the consolidated statements of income. These contracts were highly effective in hedging the variability in future cash flows attributable to changes in currency exchange rates at March 31, 2015, September 30, 2014 and March 31, 2014. The fair value of foreign currency exchange derivatives not designated as hedging instruments under ASC 815 are recorded in the consolidated statements of income.

Commodity derivatives – The Company selectively hedges anticipated transactions that are subject to commodity price risk, primarily using commodity hedge contracts, to minimize overall price risk associated with the Company’s purchases of lead, copper, tin and aluminum. The commodity derivatives are valued under a market approach using publicized prices, where available, or dealer quotes. As cash flow hedges, the effective portion of the hedge gains or losses due to changes in fair value are initially recorded as a component of accumulated other comprehensive income and are subsequently reclassified into earnings when the hedged transactions, typically sales, occur and affect earnings. Any ineffective portion of the hedge is reflected in the consolidated statements of income. These contracts were highly effective in hedging the variability in future cash flows attributable to changes in commodity prices at March 31, 2015, September 30, 2014 and March 31, 2014.

Interest rate swaps and related debt – The Company selectively uses interest rate swaps to reduce market risk associated with changes in interest rates for its fixed-rate bonds. As fair value hedges, the interest rate swaps and related debt balances are valued under a market approach using publicized swap curves. Changes in the fair value of the swap and hedged portion of the debt are recorded in the consolidated statements of income. In the second quarter of fiscal 2011, the Company entered into five fixed to floating interest rate swaps totaling $450 million to hedge the coupon of its 1.75% notes that matured in March 2014. In the fourth quarter of fiscal 2013, the Company entered into one fixed to floating interest rate swap totaling approximately $125 million to hedge the coupon of its 7.7% notes that matured in March 2015 and four fixed to floating interest rate swaps totaling $800 million to hedge the coupon of its 5.5% notes maturing January 2016. In the third quarter of fiscal 2014, the Company entered into four fixed to floating interest rate swaps totaling $400 million to hedge the coupon of its 2.6% notes maturing December 2016, three fixed to floating interest rate swaps totaling $300 million to hedge the coupon of its 1.4% notes maturing November 2017 and one fixed to floating interest rate swap totaling $150 million to hedge the coupon of its 7.125% coupon maturing July 2017. There were twelve interest rate swaps outstanding as of March 31, 2015, thirteen interest rate swaps outstanding as of September 30, 2014 and five interest rate swaps outstanding as of March 31, 2014.

Cross-currency interest rate swaps – The Company selectively uses cross-currency interest rate swaps to hedge the foreign currency rate risk associated with certain of its investments in Japan. The cross-currency interest rate swaps are valued using observable market data. Changes in the market value of the swaps are reflected in the foreign currency translation adjustments component of accumulated other comprehensive income where they offset gains and losses recorded on the Company’s net investment in Japan. At March 31, 2015, September 30, 2014 and March 31, 2014, the Company had four cross-currency interest rate swaps outstanding totaling 20 billion yen.

Investments in marketable common stock – The Company invests in certain marketable common stock, which is valued under a market approach using publicized share prices. There were no unrealized gains or losses recorded in accumulated other comprehensive income on these investments as of March 31, 2015, September 30, 2014 and March 31, 2014. During the six months ended March 31, 2014, the Company sold certain marketable common stock for approximately $25 million. As a result, the Company recorded $8 million of realized gains within selling, general and administrative expenses in the Automotive Experience Seating segment.

Equity swaps – The Company selectively uses equity swaps to reduce market risk associated with certain of its stock-based compensation plans, such as its deferred compensation plans. The equity swaps are valued under a market approach as the fair value of the swaps is equal to the Company’s stock price at the reporting period date. Changes in fair value on the equity swaps are reflected in the consolidated statements of income within selling, general and administrative expenses.

The fair values of cash and cash equivalents, accounts receivable, short-term debt and accounts payable approximate their carrying values. The fair value of long-term debt, which was $6.8 billion, $6.8 billion and $5.2 billion at March 31, 2015, September 30, 2014 and March 31, 2014, respectively, was determined primarily using market quotes classified as Level 1 inputs within the ASC 820 fair value hierarchy.

Commitments and Contingencies

Commitments and Contingencies

The Company accrues for potential environmental liabilities when it is probable a liability has been incurred and the amount of the liability is reasonably estimable. Reserves for environmental liabilities totaled $22 million, $24 million and $24 million at March 31, 2015, September 30, 2014 and March 31, 2014, respectively. The Company reviews the status of its environmental sites on a quarterly basis and adjusts its reserves accordingly. Such potential liabilities accrued by the Company do not take into consideration possible recoveries of future insurance proceeds. They do, however, take into account the likely share other parties will bear at remediation sites. It is difficult to estimate the Company’s ultimate level of liability at many remediation sites due to the large number of other parties that may be involved, the complexity of determining the relative liability among those parties, the uncertainty as to the nature and scope of the investigations and remediation to be conducted, the uncertainty in the application of law and risk assessment, the various choices and costs associated with diverse technologies that may be used in corrective actions at the sites, and the often quite lengthy periods over which eventual remediation may occur. Nevertheless, the Company does not currently believe that any claims, penalties or costs in connection with known environmental matters will have a material adverse effect on the Company’s financial position, results of operations or cash flows. In addition, the Company has identified asset retirement obligations for environmental matters that are expected to be addressed at the retirement, disposal, removal or abandonment of existing owned facilities, primarily in the Power Solutions business. At March 31, 2015, September 30, 2014 and March 31, 2014, the Company recorded conditional asset retirement obligations of $64 million, $52 million and $58 million, respectively.

The Company is involved in various lawsuits, claims and proceedings incident to the operation of its businesses, including those pertaining to product liability, environmental, safety and health, intellectual property, employment, commercial and contractual matters, and various other casualty matters. Although the outcome of litigation cannot be predicted with certainty and some lawsuits, claims or proceedings may be disposed of unfavorably to us, it is management’s opinion that none of these will have a material adverse effect on the Company’s financial position, results of operations or cash flows. Costs related to such matters were not material to the periods presented.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Financial Statements

Financial Statements

In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments (which include normal recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows for the periods presented. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) have been omitted pursuant to the rules and regulations of the United States Securities and Exchange Commission (SEC). These consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Johnson Controls, Inc. (the "Company") Annual Report on Form 10-K for the year ended September 30, 2014. The results of operations for the three and six month periods ended March 31, 2015 are not necessarily indicative of results for the Company’s 2015 fiscal year because of seasonal and other factors.

The consolidated financial statements include the accounts of Johnson Controls, Inc. and its domestic and non-U.S. subsidiaries that are consolidated in conformity with U.S. GAAP. All significant intercompany transactions have been eliminated. Investments in partially-owned affiliates are accounted for by the equity method when the Company’s interest exceeds 20% and the Company does not have a controlling interest.

Under certain criteria as provided for in Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 810, "Consolidation," the Company may consolidate a partially-owned affiliate. To determine whether to consolidate a partially-owned affiliate, the Company first determines if the entity is a variable interest entity (VIE). An entity is considered to be a VIE if it has one of the following characteristics: 1) the entity is thinly capitalized; 2) residual equity holders do not control the entity; 3) equity holders are shielded from economic losses or do not participate fully in the entity’s residual economics; or 4) the entity was established with non-substantive voting. If the entity meets one of these characteristics, the Company then determines if it is the primary beneficiary of the VIE. The party with the power to direct activities of the VIE that most significantly impact the VIE’s economic performance and the potential to absorb benefits or losses that could be significant to the VIE is considered the primary beneficiary and consolidates the VIE. If the entity is not considered a VIE, then the Company applies the voting interest model to determine whether or not the Company shall consolidate the partially-owned affiliate.

Consolidated VIEs

Based upon the criteria set forth in ASC 810, the Company has determined that it was the primary beneficiary in three VIEs for the reporting periods ended March 31, 2015, September 30, 2014 and March 31, 2014, as the Company absorbs significant economics of the entities and has the power to direct the activities that are considered most significant to the entities.

Two of the VIEs manufacture products in North America for the automotive industry. The Company funds the entities’ short term liquidity needs through revolving credit facilities and has the power to direct the activities that are considered most significant to the entities through its key customer supply relationships.

In fiscal 2012, a pre-existing VIE accounted for under the equity method was reorganized into three separate investments as a result of the counterparty exercising its option to put its interest to the Company. The Company acquired additional interests in two of the reorganized group entities. The reorganized group entities are considered to be VIEs as the other owner party has been provided decision making rights but does not have equity at risk. The Company is considered the primary beneficiary of one of the entities due to the Company’s power pertaining to decisions over significant activities of the entity. As such, this VIE has been consolidated within the Company’s consolidated statements of financial position. The impact of consolidation of the entity on the Company’s consolidated statements of income for the three and six month periods ended March 31, 2015 and 2014 was not material. The VIE is named as a co-obligor under a third party debt agreement of $164 million, maturing in fiscal 2020, under which it could become subject to paying more than its allocated share of the third party debt in the event of bankruptcy of one or more of the other co-obligors. The other co-obligors, all related parties in which the Company is an equity investor, consist of the remaining group entities involved in the reorganization. As part of the overall reorganization transaction, the Company has also provided financial support to the group entities in the form of loans totaling $58 million, which are subordinate to the third party debt agreement. The Company is a significant customer of certain co-obligors, resulting in a remote possibility of loss. Additionally, the Company is subject to a floor guaranty expiring in fiscal 2022; in the event that the other owner party no longer owns any part of the group entities due to sale or transfer, the Company has guaranteed that the proceeds received from the sale or transfer will not be less than $25 million. The Company has partnered with the group entities to design and manufacture battery components for the Power Solutions business.

The carrying amounts and classification of assets (none of which are restricted) and liabilities included in the Company’s consolidated statements of financial position for the consolidated VIEs are as follows (in millions):

	March 31, 2015		September 30, 2014		March 31, 2014
Current assets	$	269	$	218	$	296
Noncurrent assets	134		138		137
Total assets	$	403	$	356	$	433
Current liabilities	$	200	$	189	$	195
Noncurrent liabilities	35		37		38
Total liabilities	$	235	$	226	$	233

The Company did not have a significant variable interest in any other consolidated VIEs for the presented reporting periods.

Nonconsolidated VIEs

As mentioned previously within the "Consolidated VIEs" section above, in fisca1 2012, a pre-existing VIE was reorganized into three separate investments as a result of the counterparty exercising its option to put its interest to the Company. The reorganized group entities are considered to be VIEs as the other owner party has been provided decision making rights but does not have equity at risk. The Company is not considered to be the primary beneficiary of two of the entities as the Company cannot make key operating decisions considered to be most significant to the VIEs. Therefore, the entities are accounted for under the equity method of accounting as the Company’s interest exceeds 20% and the Company does not have a controlling interest. The Company’s maximum exposure to loss includes the partially-owned affiliate investment balance of $60 million, $59 million and $60 million at March 31, 2015, September 30, 2014 and March 31, 2014, respectively, as well as the subordinated loan from the Company, third party debt agreement and floor guaranty mentioned previously within the "Consolidated VIEs" section above. Current liabilities due to the VIEs are not material and represent normal course of business trade payables for all presented periods.

The Company did not have a significant variable interest in any other unconsolidated VIEs for the presented reporting periods.

Restricted Cash

At March 31, 2015, September 30, 2014 and March 31, 2014, the Company held restricted cash of approximately $8 million, $4 million and $22 million, respectively, within cash and cash equivalents. These amounts were collected from customers for payment of maintenance costs under contract, and withdrawals are restricted for this purpose.

Retrospective Changes

At March 31, 2015, the Company determined that its Building Efficiency Global Workplace Solutions (GWS) segment met the criteria to be classified as a discontinued operation, which required retrospective application to financial information for all periods presented. Refer to Note 4, "Discontinued Operations," of the notes to consolidated financial statements for further information regarding the Company's discontinued operations.

Segment Reporting, Disclosure of Entity's Reportable Segments [Abstract]

Segment Information

Segment Information

At March 31, 2015, the Company determined that its GWS segment met the criteria to be classified as a discontinued operation, which required retrospective application to financial information for all periods presented. Refer to Note 4, "Discontinued Operations," of the notes to consolidated financial statements for further information regarding the Company's discontinued operations.

ASC 280, "Segment Reporting," establishes the standards for reporting information about segments in financial statements. In applying the criteria set forth in ASC 280, the Company has determined that it has six reportable segments for financial reporting purposes. The Company’s six reportable segments are presented in the context of its three primary businesses – Building Efficiency, Automotive Experience and Power Solutions.

Building Efficiency

Building Efficiency designs, produces, markets and installs heating, ventilating and air conditioning (HVAC) and control systems that monitor, automate and integrate critical building segment equipment and conditions including HVAC, fire-safety and security in commercial buildings and in various industrial applications.

• North America Systems and Service provides HVAC and controls systems, energy efficient solutions and technical services, including inspection, scheduled maintenance, and repair and replacement of mechanical and control systems to non-residential buildings and industrial applications in the North American marketplace.

• Asia provides HVAC and refrigeration systems and technical services to the Asian marketplace.

• Other provides HVAC and refrigeration systems and technical services to markets in Europe, the Middle East and Latin America. Other also designs and produces heating and air conditioning solutions for residential and light commercial applications, and markets products to the replacement and new construction markets.

Automotive Experience

Automotive Experience designs and manufactures interior systems and products for passenger cars and light trucks, including vans, pick-up trucks and sport utility/crossover vehicles.

• Seating produces automotive seat metal structures and mechanisms, foam, trim, fabric and complete seat systems.

• Interiors produces instrument panels, floor consoles and door panels.

Power Solutions

Power Solutions services both automotive original equipment manufacturers and the battery aftermarket by providing advanced battery technology, coupled with systems engineering, marketing and service expertise.

Management evaluates the performance of the segments based primarily on segment income, which represents income from continuing operations before income taxes and noncontrolling interests excluding net financing charges, significant restructuring and impairment costs, and net mark-to-market adjustments on pension and postretirement plans. General corporate and other overhead expenses are allocated to business segments in determining segment income. As mentioned above, the previously reported GWS segment met the criteria to be classified as a discontinued operation, and general corporate overhead was not allocated to discontinued operations. The Company reported discontinued operations through retrospective application to all periods presented, resulting in general corporate allocation changes between the segments in the prior periods. Financial information relating to the Company’s reportable segments is as follows (in millions):

Earnings Per Share

Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

The Company presents both basic and diluted earnings per share (EPS) amounts. Basic EPS is calculated by dividing net income attributable to Johnson Controls, Inc. by the weighted average number of common shares outstanding during the reporting period. Diluted EPS is calculated by dividing net income attributable to Johnson Controls, Inc. by the weighted average number of common shares and common equivalent shares outstanding during the reporting period that are calculated using the treasury stock method for stock options and unvested restricted stock. The treasury stock method assumes that the Company uses the proceeds from the exercise of stock option awards to repurchase common stock at the average market price during the period. The assumed proceeds under the treasury stock method include the purchase price that the grantee will pay in the future, compensation cost for future service that the Company has not yet recognized and any windfall tax benefits that would be credited to capital in excess of par value when the award generates a tax deduction. If there would be a shortfall resulting in a charge to capital in excess of par value, such an amount would be a reduction of the proceeds. For unvested restricted stock, assumed proceeds under the treasury stock method would include unamortized compensation cost and windfall tax benefits or shortfalls.

The following table reconciles the numerators and denominators used to calculate basic and diluted earnings per share (in millions):

The Company's fiscal 2014, 2013 and 2012 restructuring plans included workforce reductions of approximately 20,600 employees (11,000 for the Automotive Experience business, 8,500 for the Building Efficiency business and 1,100 for the Power Solutions business). Restructuring charges associated with employee severance and termination benefits are paid over the severance period granted to each employee or on a lump sum basis in accordance with individual severance agreements. As of March 31, 2015, approximately 15,900 of the employees have been separated from the Company pursuant to the restructuring plans. In addition, the restructuring plans included twenty-eight plant closures (twenty for Automotive Experience, six for Building Efficiency and two for Power Solutions). As of March 31, 2015, seventeen of the twenty-eight plants have been closed.

Company management closely monitors its overall cost structure and continually analyzes each of its businesses for opportunities to consolidate current operations, improve operating efficiencies and locate facilities in low cost countries in close proximity to customers. This ongoing analysis includes a review of its manufacturing, engineering and purchasing operations, as well as the overall global footprint for all its businesses. Because of the importance of new vehicle sales by major automotive manufacturers to operations, the Company is affected by the general business conditions in this industry. Future adverse developments in the automotive industry could impact the Company’s liquidity position, lead to impairment charges and/or require additional restructuring of its operations.

At March 31, 2014, accumulated goodwill impairment charges include $430 million related to the Automotive Experience Interiors segment. The six months ended September 30, 2014 GWS business divestiture amount includes $253 million of goodwill transferred to assets held for sale on the consolidated statement of financial position. The six months ended September 30, 2014 Automotive Experience Interiors business divestiture amount includes $12 million of goodwill transferred to noncurrent assets held for sale on the consolidated statement of financial position. The six months ended March 31, 2015 Automotive Experience Interiors business divestiture amount includes $9 million of goodwill transferred to noncurrent assets held for sale on the consolidated statement of financial position. Refer to Note 4, "Discontinued Operations," of the notes to consolidated financial statements for further information regarding the Company's assets and liabilities held for sale.

During the six months ended September 30, 2014, as a result of recent operating results, restructuring actions and expected future profitability, the Company's forecasted cash flow estimates used in the goodwill assessment were negatively impacted as of September 30, 2014 for the Building Efficiency Other - Latin America reporting unit. As a result, the Company concluded that the carrying value of the Building Efficiency Other - Latin America reporting unit exceeded its fair value as of September 30, 2014. The Company recorded a goodwill impairment charge of $47 million in the fourth quarter of fiscal 2014, which was determined by comparing the carrying value of the reporting unit's goodwill with the implied fair value of goodwill for the reporting unit. The Building Efficiency Other - Latin America reporting unit had no remaining goodwill at September 30, 2014.

The Company's impairment testing in the fourth quarter of fiscal 2014 indicated that the estimated fair value of the Building Efficiency Other - Middle East reporting unit exceeded its corresponding carrying amount including goodwill by approximately 9%. Accordingly, the Company has not recognized any impairment of goodwill associated with this reporting unit, which as of March 31, 2015 had a goodwill balance of $85 million. The Company continuously monitors for events and circumstances that could negatively impact the key assumptions in determining fair value, including long-term revenue growth projections, profitability, discount rates, recent market valuations from transactions by comparable companies, volatility in the Company's market capitalization, and general industry, market and macro-economic conditions. It is possible that future changes in such circumstances, or in the variables associated with the judgments, assumptions and estimates used in assessing the fair value of the reporting unit, would require the Company to record a non-cash impairment charge.

The assumptions included in the impairment test required judgment, and changes to the inputs could impact the results of the calculation. Other than management's internal projections of future cash flows, the primary assumptions used in the impairment test was the weighted-average cost of capital and long-term growth rates. Although the Company's cash flow forecasts are based on assumptions that are considered reasonable by management and consistent with the plans and estimates management is using to operate the underlying businesses, there are significant judgments in determining the expected future cash flows.

Product Warranties Disclosures [Abstract]

Product Warranties

Product Warranties

The Company offers warranties to its customers depending upon the specific product and terms of the customer purchase agreement. A typical warranty program requires that the Company replace defective products within a specified time period from the date of sale. The Company records an estimate for future warranty-related costs based on actual historical return rates and other known factors. Based on analysis of return rates and other factors, the Company’s warranty provisions are adjusted as necessary. The Company monitors its warranty activity and adjusts its reserve estimates when it is probable that future warranty costs will be different than those estimates.

The Company’s product warranty liability is recorded in the consolidated statements of financial position in other current liabilities if the warranty is less than one year and in other noncurrent liabilities if the warranty extends longer than one year.

The changes in the carrying amount of the Company’s total product warranty liability, including extended warranties for which deferred revenue is recorded, for the six months ended March 31, 2015 and 2014 were as follows (in millions):

Income Taxes

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

In calculating the provision for income taxes, the Company uses an estimate of the annual effective tax rate based upon the facts and circumstances known at each interim period. On a quarterly basis, the actual effective tax rate is adjusted, as appropriate, based upon changed facts and circumstances, if any, as compared to those forecasted at the beginning of the fiscal year and each interim period thereafter. For the three and six months ended March 31, 2015, the Company's effective tax rate for continuing operations was 22% and 20%, respectively. The effective rate was lower than the U.S. federal statutory rate of 35% primarily due to global tax planning and foreign tax rate differentials, partially offset by a tax rate change in Japan. For the three and six months ended March 31, 2014, the Company's effective tax rate for continuing operations was 19% for both periods. The effective rate was lower than the U.S. federal statutory rate of 35% primarily due to global tax planning and foreign tax rate differentials.

Valuation Allowance

The Company reviews the realizability of its deferred tax assets on a quarterly basis, or whenever events or changes in circumstances indicate that a review is required. In determining the requirement for a valuation allowance, the historical and projected financial results of the legal entity or consolidated group recording the net deferred tax asset are considered, along with any other positive or negative evidence. Since future financial results may differ from previous estimates, periodic adjustments to the Company’s valuation allowances may be necessary.

In the first quarter of fiscal 2014, the Company determined that it was more likely than not that a deferred tax asset associated with a capital loss in Mexico would not be utilized. Therefore, the Company recorded a $21 million valuation allowance as income tax expense.

Uncertain Tax Positions

At September 30, 2014, the Company had gross tax effected unrecognized tax benefits of $1,655 million, of which $1,505 million, if recognized, would impact the effective tax rate. Total net accrued interest at September 30, 2014 was approximately $106 million (net of tax benefit). The net change in interest and penalties during the six months ended March 31, 2015 and 2014 was not material. The Company recognizes interest and penalties related to unrecognized tax benefits as a component of income tax expense.

In the first quarter of fiscal 2015, the Company settled tax audits in multiple jurisdictions. The benefit of those settlements was substantially offset by a net tax provision recorded in the quarter where it was more likely than not that the losses would not be realized.

In the U.S., fiscal years 2010 through 2012 are currently under exam by the Internal Revenue Service (IRS) and 2007 through 2009 are currently under IRS appeals. Additionally, the Company is currently under exam in the following major foreign jurisdictions:

Tax Jurisdiction	Tax Years Covered
Belgium	2012 - 2014
Brazil	2004 - 2008, 2011 - 2012
Canada	2007 - 2012
France	2002 - 2013
Germany	2001 - 2012
Italy	2005 - 2009, 2011
Korea	2008 - 2012
Mexico	2003 - 2004, 2007 - 2013
Slovakia	2012
United Kingdom	2011 - 2012

It is reasonably possible that certain tax examinations, appellate proceedings and/or tax litigation will conclude within the next twelve months, the impact of which could be up to a $70 million benefit to tax expense.

Impacts of Tax Legislation

During the six months ended March 31, 2015, tax legislation was adopted in Japan which reduced its statutory income tax rate. As a result of the law change, the Company recorded income tax expense of $17 million. Tax legislation was also adopted in various other jurisdictions during the six month period ended March 31, 2015, and these changes did not have a material impact on the Company's consolidated financial statements.

The "look-through rule," under subpart F of the U.S. Internal Revenue Code, expired for the Company on September 30, 2014. The "look-through rule" had provided an exception to the U.S. taxation of certain income generated by foreign subsidiaries. The rule was extended in December 2014 retroactive to the beginning of the Company's 2015 fiscal year.

As a result of changes to Mexican tax law in the first quarter of fiscal 2014, the Company recorded a benefit to income tax expense of $25 million.

Derivative Instruments and Hedging Activities

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments and Hedging Activities

Derivative Instruments and Hedging Activities

The Company selectively uses derivative instruments to reduce market risk associated with changes in foreign currency, commodities, stock-based compensation liabilities and interest rates. Under Company policy, the use of derivatives is restricted to those intended for hedging purposes; the use of any derivative instrument for speculative purposes is strictly prohibited. A description of each type of derivative utilized by the Company to manage risk is included in the following paragraphs. In addition, refer to Note 16, "Fair Value Measurements," of the notes to consolidated financial statements for information related to the fair value measurements and valuation methods utilized by the Company for each derivative type.

The Company has global operations and participates in the foreign exchange markets to minimize its risk of loss from fluctuations in foreign currency exchange rates. The Company primarily uses foreign currency exchange contracts to hedge certain of its foreign exchange rate exposures. The Company hedges 70% to 90% of the nominal amount of each of its known foreign exchange transactional exposures.

The Company has entered into cross-currency interest rate swaps to selectively hedge portions of its net investment in Japan. The currency effects of the cross-currency interest rate swaps are reflected in the accumulated other comprehensive income (AOCI) account within shareholders’ equity attributable to Johnson Controls, Inc. where they offset gains and losses recorded on the Company’s net investment in Japan. At March 31, 2015, September 30, 2014 and March 31, 2014 the Company had four cross-currency interest rate swaps outstanding totaling 20 billion yen.

The Company uses commodity contracts in the financial derivatives market in cases where commodity price risk cannot be naturally offset or hedged through supply base fixed price contracts. Commodity risks are systematically managed pursuant to policy guidelines. As cash flow hedges, the effective portion of the hedge gains or losses due to changes in fair value are initially recorded as a component of AOCI and are subsequently reclassified into earnings when the hedged transactions, typically sales, occur and affect earnings. Any ineffective portion of the hedge is reflected in the consolidated statements of income. The maturities of the commodity contracts coincide with the expected purchase of the commodities. The Company had the following outstanding commodity hedge contracts that hedge forecasted purchases:

		Volume Outstanding as of
Commodity	Units	March 31, 2015	September 30, 2014	March 31, 2014
Copper	Pounds	7,805,000	9,536,000	15,950,000
Lead	Metric Tons	10,952	5,200	—
Aluminum	Metric Tons	1,830	—	493
Tin	Metric Tons	1,000	2,070	957

The Company selectively uses equity swaps to reduce market risk associated with certain of its stock-based compensation plans, such as its deferred compensation plans. These equity compensation liabilities increase as the Company’s stock price increases and decrease as the Company’s stock price decreases. In contrast, the value of the swap agreement moves in the opposite direction of these liabilities, allowing the Company to fix a portion of the liabilities at a stated amount. As of March 31, 2015, September 30, 2014 and March 31, 2014, the Company had hedged approximately 4.1 million, 4.4 million and 4.6 million shares of its common stock, respectively.

The Company selectively uses interest rate swaps to reduce market risk associated with changes in interest rates for its fixed-rate bonds. As fair value hedges, the interest rate swaps and related debt balances are valued under a market approach using publicized swap curves. Changes in the fair value of the swap and hedged portion of the debt are recorded in the consolidated statements of income. In the second quarter of fiscal 2011, the Company entered into five fixed to floating interest rate swaps totaling $450 million to hedge the coupon of its 1.75% notes that matured in March 2014. In the fourth quarter of fiscal 2013, the Company entered into one fixed to floating interest rate swap totaling approximately $125 million to hedge the coupon of its 7.7% notes that matured in March 2015 and four fixed to floating interest rate swaps totaling $800 million to hedge the coupon of its 5.5% notes maturing January 2016. In the third quarter of fiscal 2014, the Company entered into four fixed to floating interest rate swaps totaling $400 million to hedge the coupon of its 2.6% notes maturing December 2016, three fixed to floating interest rate swaps totaling $300 million to hedge the coupon of its 1.4% notes maturing November 2017 and one fixed to floating interest rate swap totaling $150 million to hedge the coupon of its 7.125% coupon maturing July 2017. There were twelve interest rate swaps outstanding as of March 31, 2015, thirteen interest rate swaps outstanding as of September 30, 2014 and five interest rate swaps outstanding as of March 31, 2014.

In September 2005, the Company entered into three forward treasury lock agreements to reduce the market risk associated with changes in interest rates associated with the Company’s anticipated fixed-rate note issuance to finance the acquisition of York International (cash flow hedge). The three forward treasury lock agreements, which had a combined notional amount of $1.3 billion, fixed a portion of the future interest cost for 5-year, 10-year and 30-year notes. The fair value of each treasury lock agreement, or the difference between the treasury lock reference rate and the fixed rate at time of note issuance, is amortized to interest expense over the life of the respective note issuance. In January 2006, in connection with the Company’s debt refinancing, the three forward treasury lock agreements were terminated.

The following table presents the location and fair values of derivative instruments and hedging activities included in the Company’s consolidated statements of financial position (in millions):

The Company enters into International Swaps and Derivatives Associations (ISDA) master netting agreements with counterparties that permit the net settlement of amounts owed under the derivative contracts. The master netting agreements generally provide for net settlement of all outstanding contracts with a counterparty in the case of an event of default or a termination event. The Company has not elected to offset the fair value positions of the derivative contracts recorded in the consolidated statements of financial position. Collateral is generally not required of the Company or the counterparties under the master netting agreements. As of March 31, 2015, September 30, 2014 and March 31, 2014, no cash collateral was received or pledged under the master netting agreements.

The gross and net amounts of derivative assets and liabilities were as follows (in millions):

Discontinued Operations

4. Discontinued Operations

In the second quarter of fiscal 2015, the Company completed the sale of its interests in two GWS joint ventures to Brookfield Asset Management, Inc. On March 31, 2015, the Company announced that it had reached a definitive agreement to sell the remainder of the GWS business to CBRE Group Inc., subject to regulatory and other approvals. The agreement includes a 10-year strategic relationship between the Company and CBRE. The Company will be the preferred provider of HVAC equipment, building automation systems and related services to the portfolio of real estate and corporate facilities managed globally by CBRE and GWS. The Company also expects to engage GWS for facility management services. The annual cash flows resulting from these activities with the legacy GWS business are not expected to be significant. The sale is expected to close near the end of fiscal 2015.

At March 31, 2015, the Company determined that its GWS segment met the criteria to be classified as a discontinued operation, which required retrospective application to financial information for all periods presented. The Company did not allocate any general corporate overhead to discontinued operations. The assets and liabilities of the GWS segment were reflected as held for sale in the consolidated statements of financial position at March 31, 2015 and September 30, 2014.

The following table summarizes the results of GWS, reclassified as discontinued operations for the three and six month periods ended March 31, 2015 and 2014 (in millions):

	Three Months Ended March 31,				Six Months Ended March 31,
	2015		2014		2015		2014
Net sales	$	803	$	996	$	1,845	$	2,073
Income from discontinued operations before income taxes	227		36		269		65
Provision for income taxes on discontinued operations	149		9		162		17
Income from discontinued operations attributable to noncontrolling interests, net of tax	1		4		4		7
Income from discontinued operations	$	77	$	23	$	103	$	41

For the three and six months ended March 31, 2015, the income from discontinued operations before income taxes included a $200 million gain on divestiture of the Company's interest in two GWS joint ventures. For the three and six months ended March 31, 2015, the income from discontinued operations before income taxes included current year transaction costs of $10 million and $17 million, respectively.

For the three and six months ended March 31, 2015, the effective tax rate was greater than the U.S. federal statutory rate of 35% primarily due to a second quarter discrete non-cash tax charge of $67 million related to the change in the Company's assertion over reinvestment of foreign undistributed earnings as well as the tax consequences of the sale of the GWS joint ventures, partially offset by foreign tax rate differentials. For the three and six months ended March 31, 2014, the effective tax rate was less than the U.S. federal statutory rate of 35% primarily due to foreign tax rate differentials.

In the fourth quarter of fiscal 2013, the Company completed its divestiture of its Automotive Experience Electronics' HomeLink® product line to Gentex Corporation. In the second quarter of fiscal 2014, the Company announced that it had reached a definitive agreement to sell the remainder of the Automotive Experience Electronics business to Visteon Corporation, subject to regulatory and other approvals. The sale closed on July 1, 2014. At March 31, 2014, the Company determined that the Automotive Experience Electronics segment met the criteria to be classified as a discontinued operation, which required retrospective application to financial information for all periods presented. The Company did not allocate any general corporate overhead to discontinued operations. The assets and liabilities of the Automotive Experience Electronics segment were reflected as held for sale in the consolidated statements of financial position at March 31, 2014.

There were no amounts related to the Automotive Experience Electronics business classified as discontinued operations for the three or six month periods ended March 31, 2015. The following table summarizes the results of the Automotive Experience Electronics business, classified as discontinued operations for the three and six month periods ended March 31, 2014 (in millions):

	Three Months Ended March 31,			Six Months Ended March 31,
	2014			2014
Net sales	$	344		$	678
Income from discontinued operations before income taxes	18			54
Provision for income taxes on discontinued operations	188			203
Income from discontinued operations attributable to noncontrolling interests, net of tax	2			5
Loss from discontinued operations	$	(172	)	$	(154	)

For the three and six months ended March 31, 2014, the effective tax rate was greater than the U.S. federal statutory rate of 35% primarily due to a second quarter discrete non-cash tax charge of $180 million related to the repatriation of foreign cash associated with the divestiture of the Electronics business and unbenefited foreign losses.

Assets and Liabilities Held for Sale

The Company has determined that certain of its businesses met the criteria to be classified as held for sale. In April 2015, the Company signed an agreement formally establishing the previously announced automotive interiors joint venture with Yanfeng Automotive Trim Systems. The formation of the joint venture is expected to close in the fourth quarter of fiscal 2015, pending regulatory approvals. At March 31, 2015, the Company determined certain product lines of the Automotive Experience Interiors segment which are not to be contributed to the aforementioned automotive interiors joint venture met the criteria to be classified as held for sale. As a result, a majority of the Automotive Experience Interiors business met the criteria to be classified as held for sale.

The following table summarizes the carrying value of the Interiors and GWS assets and liabilities held for sale (in millions):

	March 31, 2015						September 30, 2014

Liabilities held for sale	$	858	$	653	$	1,511	$	833	$	968	$	1,801

These divestitures could result in a gain or loss on sale to the extent the ultimate selling price or contribution value differs from the carrying value of the net assets recorded for each business. The Interiors businesses classified as held for sale do not meet the criteria to be classified as a discontinued operation at March 31, 2015 primarily due to the Company's anticipated continuing involvement in these operations following a divestiture and the immateriality of certain product lines to the Company.

The Automotive Experience Electronics segment and the headliner and sun visor product lines were classified as held for sale beginning September 30, 2013. The headliner and sun visor product lines and the Automotive Experience Electronics segment were sold during the third and fourth quarters of fiscal 2014, respectively.

The following table summarizes the carrying value of the Electronics and headliner and sun visor assets and liabilities held for sale (in millions):

	March 31, 2014
Cash and cash equivalents	$	3
Accounts receivable - net	214
Inventories	128
Other current assets	63
Property, plant and equipment - net	174
Goodwill	74

The headliner and sun visor product lines classified as held for sale were immaterial to the Company individually and in the aggregate, and did not constitute a distinguishable business in order to be classified as a discontinued operation.

In November 2013, the Company's Board of Directors authorized a $3 billion increase in the Company's share repurchase program, which brought the total authorized amount under the repurchase program to $3.65 billion. The share repurchase program does not have an expiration date and may be amended or terminated by the Board of Directors at any time without prior notice. For the three month periods ended March 31, 2015, the Company repurchased approximately $210 million of its common shares. For the six month periods ended March 31, 2015 and 2014, the Company repurchased approximately $810 million and $1.2 billion of its common shares, respectively.

The Company consolidates certain subsidiaries in which the noncontrolling interest party has within its control the right to require the Company to redeem all or a portion of its interest in the subsidiary. The redeemable noncontrolling interests are reported at their estimated redemption value. Any adjustment to the redemption value impacts retained earnings but does not impact net income. Redeemable noncontrolling interests which are redeemable only upon future events, the occurrence of which is not currently probable, are recorded at carrying value.

The following schedules present changes in the redeemable noncontrolling interests (in millions):
