Notes to the Interim Consolidated Financial Information (unaudited) Note 1 The Company and basis of presentation ABB Ltd and its subsidiaries (collectively, the Company) together form a leading global technology company in power and automation that enables utility, industry, and transport & infrastructure customers to improve their performance while lowering environmental impact. The Company works with customers to engineer and install networks, facilities and plants with particular emphasis on enhancing efficiency, reliability and productivity for customers who generate, convert, transmit, distribute and consume energy. The Company’s Interim Consolidated Financial Information is prepared in accordance with United States of America generally accepted accounting principles (U.S. GAAP) for interim financial reporting. As such, the Interim Consolidated Financial Information does not include all the information and notes required under U.S. GAAP for annual consolidated financial statements. Therefore, such financial information should be read in conjunction with the audited consolidated financial statements in the Company’s Annual Report for the year ended December 31, 2015. The preparation of financial information in conformity with U.S. GAAP requires management to make assumptions and estimates that directly affect the amounts reported in the Interim Consolidated Financial Information. The most significant, difficult and subjective of such accounting assumptions and estimates include: - assumptions and projections, principally related to future material, labor and project-related overhead costs, used in determining the percentage-of-completion on projects, - estimates of loss contingencies associated with litigation or threatened litigation and other claims and inquiries, environmental damages, product warranties, self-insurance reserves, regulatory and other proceedings, - assumptions used in the calculation of pension and postretirement benefits and the fair value of pension plan assets, - recognition and measurement of current and deferred income tax assets and liabilities (including the measurement of uncertain tax positions), - growth rates, discount rates and other assumptions used in testing goodwill for impairment, - assumptions used in determining inventory obsolescence and net realizable value, - estimates and assumptions used in determining the fair values of assets and liabilities assumed in business combinations, - growth rates, discount rates and other assumptions used to determine impairment of long-lived assets, and - assessment of the allowance for doubtful accounts. The actual results and outcomes may differ from the Company’s estimates and assumptions. A portion of the Company’s activities (primarily long-term construction activities) has an operating cycle that exceeds one year. For classification of current assets and liabilities related to such activities, the Company elected to use the duration of the individual contracts as its operating cycle. Accordingly, there are accounts receivable, inventories and provisions related to these contracts which will not be realized within one year that have been classified as current. In the opinion of management, the unaudited Interim Consolidated Financial Information contains all necessary adjustments to present fairly the financial position, results of operations and cash flows for the reported interim periods. Management considers all such adjustments to be of a normal recurring nature. The Interim Consolidated Financial Information is presented in United States dollars ($) unless otherwise stated. Certain amounts have been reclassified to conform to the current period presentation. Adjustment related to prior periods In the three months ended March 31, 2016, the Company recorded a cumulative correction to eliminate certain intercompany self-insurance reserves. The correction resulted in a $50 million reduction in “Total cost of sales” in the Interim Consolidated Income Statements for the three months ended March 31, 2016, and is included in Corporate and Other Operational EBITA. The Company evaluated the impact of the correction on both a quantitative and qualitative basis under the guidance of ASC 250, Accounting Changes and Error Corrections, and determined that there were no material impacts on the trend of net income, cash flows or liquidity for previously issued annual financial statements. Additionally, the Company does not expect its consolidated financial statements for the current annual period to be materially impacted by the correction. Note 2 Recent accounting pronouncements Applicable for current periods Disclosures for investments in certain entities that calculate net asset value per share (or its equivalent) As of January 1, 2016, the Company adopted an accounting standard update regarding fair value disclosures for certain investments. Under the update, the Company will no longer categorize within the fair value hierarchy any investments for which fair value is measured using the net asset value per share practical expedient. The amendments also removed the requirement to make certain disclosures for investments that are eligible to be measured at fair value using the net asset value per share practical expedient. Rather, those disclosures are limited to investments for which the Company has elected to measure the fair value using that practical expedient. This update was applied retrospectively and did not have a significant impact on the consolidated financial statements. Simplifying the measurement of inventory As of January 1, 2016, the Company early-adopted an accounting standard update simplifying the subsequent measurement of inventories by replacing the current lower of cost or market test with a lower of cost and net realizable value test. The guidance applies only to inventories for which cost is determined by methods other than last-in first-out and the retail inventory method. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The update was applied prospectively and did not have a significant impact on the consolidated financial statements.

Applicable for future periods Revenue from contracts with customers In May 2014, an accounting standard update was issued to clarify the principles for recognizing revenues from contracts with customers. The update, which supersedes substantially all existing revenue recognition guidance, provides a single comprehensive model for recognizing revenues on the transfer of promised goods or services to customers in an amount that reflects the consideration that is expected to be received for those goods or services. Under the standard it is possible that more judgments and estimates would be required than under existing standards, including identifying the separate performance obligations in a contract, estimating any variable consideration elements, and allocating the transaction price to each separate performance obligation. The update also requires additional disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Further updates were issued in March and April 2016 to clarify the guidance on identifying performance obligations and to enhance the implementation guidance on principle versus agent considerations and licensing. In August 2015, the effective date for the update was deferred and the update is now effective for the Company for annual and interim periods beginning January 1, 2018, and is to be applied either (i) retrospectively to each prior reporting period presented, with the option to elect certain defined practical expedients, or (ii) retrospectively with the cumulative effect of initially applying the update recognized at the date of adoption in retained earnings (with additional disclosure as to the impact on individual financial statement lines affected). Early adoption of the standard is permitted for annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company is currently evaluating the impact of these updates on its consolidated financial statements. Balance sheet classification of deferred taxes In November 2015, an accounting standard update was issued which removes the requirement to separate deferred tax liabilities and assets into current and noncurrent amounts and instead requires all such amounts, as well as any related valuation allowance, to be classified as noncurrent in the balance sheet. This update is effective for the Company for annual and interim periods beginning January 1, 2017, with early adoption permitted, and is applicable either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. The Company is currently evaluating which transition method it will adopt and the impact of this update on its consolidated financial statements. Recognition and measurement of financial assets and financial liabilities In January 2016, an accounting standard update was issued to enhance the reporting model for financial instruments, which includes amendments to address aspects of recognition, measurement, presentation and disclosure. Amongst others, the Company would be required to measure equity investments (except those accounted for under the equity method) at fair value with changes in fair value recognized in net income and to present separately financial assets and financial liabilities by measurement category and form of financial asset. This update is effective for the Company for annual and interim periods beginning January 1, 2018, with early adoption permitted for certain provisions. The Company is currently evaluating the impact of this update on its consolidated financial statements. Leases In February 2016, an accounting standard update was issued that requires lessees to recognize lease assets and corresponding lease liabilities on the balance sheet for all leases with terms of more than 12 months. The update, which supersedes existing lease guidance, will continue to classify leases as either finance or operating, with the classification determining the pattern of expense recognition in the income statement. This update is effective for the Company for annual and interim periods beginning January 1, 2019, with early adoption permitted, and is applicable on a modified retrospective basis with various optional practical expedients. The Company is currently evaluating the impact of this update on its consolidated financial statements. Simplifying the transition to the equity method of accounting In March 2016, an accounting standard update was issued which eliminates the retroactive adjustments to an investment upon it qualifying for the equity method of accounting as a result of an increase in the level of ownership interest or degree of influence by the investor. It requires that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment qualifies for equity method accounting. This update is effective for the Company for annual and interim periods beginning January 1, 2017, with early adoption permitted, and is applicable prospectively. The Company does not believe that this update will have a significant impact on its consolidated financial statements. Improvements to employee share-based payment accounting In March 2016, an accounting standard update was issued which changes the accounting for certain aspects of share-based payment awards to employees, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as the classification in the statement of cash flows. This update is effective for the Company for annual and interim periods beginning January 1, 2017, with early adoption permitted. The Company does not believe that this update will have a significant impact on its consolidated financial statements.

At December 31, 2015, the amortized cost, gross unrecognized gain and fair value (based on quoted market prices) of these securities were $99 million, $11 million and $110 million, respectively. These securities are pledged as security for certain outstanding deposit liabilities and the funds received at the respective maturity dates of the securities will only be available to the Company for repayment of these obligations. Note 4 Derivative financial instruments The Company is exposed to certain currency, commodity, interest rate and equity risks arising from its global operating, financing and investing activities. The Company uses derivative instruments to reduce and manage the economic impact of these exposures. Currency risk Due to the global nature of the Company’s operations, many of its subsidiaries are exposed to currency risk in their operating activities from entering into transactions in currencies other than their functional currency. To manage such currency risks, the Company’s policies require the subsidiaries to hedge their foreign currency exposures from binding sales and purchase contracts denominated in foreign currencies. For forecasted foreign currency denominated sales of standard products and the related foreign currency denominated purchases, the Company’s policy is to hedge up to a maximum of 100 percent of the forecasted foreign currency denominated exposures, depending on the length of the forecasted exposures. Forecasted exposures greater than 12 months are not hedged. Forward foreign exchange contracts are the main instrument used to protect the Company against the volatility of future cash flows (caused by changes in exchange rates) of contracted and forecasted sales and purchases denominated in foreign currencies. In addition, within its treasury operations, the Company primarily uses foreign exchange swaps and forward foreign exchange contracts to manage the currency and timing mismatches arising in its liquidity management activities. Commodity risk Various commodity products are used in the Company’s manufacturing activities. Consequently it is exposed to volatility in future cash flows arising from changes in commodity prices. To manage the price risk of commodities, the Company’s policies require that the subsidiaries hedge the commodity price risk exposures from binding contracts, as well as at least 50 percent (up to a maximum of 100 percent) of the forecasted commodity exposure over the next 12 months or longer (up to a maximum of 18 months). Primarily swap contracts are used to manage the associated price risks of commodities. Interest rate risk The Company has issued bonds at fixed rates. Interest rate swaps are used to manage the interest rate risk associated with certain debt and generally such swaps are designated as fair value hedges. In addition, from time to time, the Company uses instruments such as interest rate swaps, interest rate futures, bond futures or forward rate

agreements to manage interest rate risk arising from the Company’s balance sheet structure but does not designate such instruments as hedges. Equity risk The Company is exposed to fluctuations in the fair value of its warrant appreciation rights (WARs) issued under its management incentive plan. A WAR gives its holder the right to receive cash equal to the market price of an equivalent listed warrant on the date of exercise. To eliminate such risk, the Company has purchased cash-settled call options, indexed to the shares of the Company, which entitle the Company to receive amounts equivalent to its obligations under the outstanding WARs. Volume of derivative activity In general, while the Company’s primary objective in its use of derivatives is to minimize exposures arising from its business, certain derivatives are designated and qualify for hedge accounting treatment while others either are not designated or do not qualify for hedge accounting. Foreign exchange and interest rate derivatives The gross notional amounts of outstanding foreign exchange and interest rate derivatives (whether designated as hedges or not) were as follows: Type of derivative Total notional amounts at ($ in millions) March 31, 2016 December 31, 2015 March 31, 2015 Foreign exchange contracts 17,724 16,467 17,871 Embedded foreign exchange derivatives 3,205 2,966 2,972 Interest rate contracts 4,013 4,302 4,057 Derivative commodity contracts The following table shows the notional amounts of outstanding commodity derivatives (whether designated as hedges or not), on a net basis, to reflect the Company’s requirements in the various commodities: Type of derivative Unit Total notional amounts at March 31, 2016 December 31, 2015 March 31, 2015 Copper swaps metric tonnes 49,500 48,903 53,237 Aluminum swaps metric tonnes 6,042 5,455 5,225 Nickel swaps metric tonnes 12 18 – Lead swaps metric tonnes 11,750 14,625 14,325 Zinc swaps metric tonnes 250 225 125 Silver swaps ounces 1,889,230 1,727,255 1,707,460 Crude oil swaps barrels 127,000 133,500 150,700 Equity derivatives At March 31, 2016, December 31, 2015, and March 31, 2015, the Company held 53 million, 55 million and 59 million cash-settled call options indexed to ABB Ltd shares (conversion ratio 5:1) with a total fair value of $13 million, $13 million and $26 million, respectively. Cash flow hedges As noted above, the Company mainly uses forward foreign exchange contracts to manage the foreign exchange risk of its operations, commodity swaps to manage its commodity risks and cash-settled call options to hedge its WAR liabilities. Where such instruments are designated and qualify as cash flow hedges, the effective portion of the changes in their fair value is recorded in “Accumulated other comprehensive loss” and subsequently reclassified into earnings in the same line item and in the same period as the underlying hedged transaction affects earnings. Any ineffectiveness in the hedge relationship, or hedge component excluded from the assessment of effectiveness, is recognized in earnings during the current period. At March 31, 2016, and December 31, 2015, “Accumulated other comprehensive loss” included net unrealized losses of $6 million and $11 million, respectively, net of tax, on derivatives designated as cash flow hedges. Of the amount at March 31, 2016, net losses of $2 million are expected to be reclassified to earnings in the following 12 months. At March 31, 2016, the longest maturity of a derivative classified as a cash flow hedge was 48 months. The amount of gains or losses, net of tax, reclassified into earnings due to the discontinuance of cash flow hedge accounting and the amount of ineffectiveness in cash flow hedge relationships directly recognized in earnings were not significant in the three months ended March 31, 2016 and 2015. The pre-tax effects of derivative instruments, designated and qualifying as cash flow hedges, on “Accumulated other comprehensive loss” (OCI) and the Consolidated Income Statements were as follows: Gains (losses) recognized in OCI Gains (losses) reclassified from OCI ($ in millions) on derivatives (effective portion) into income (effective portion) Three months ended March 31, 2016 2015 2016 2015 Type of derivative: Location: Foreign exchange contracts 4 (22) Total revenues (3) (13) Total cost of sales 4 5 Commodity contracts 1 (2) Total cost of sales (2) (3) Cash-settled call options – (4) SG&A expenses(1) (1) (3) Total 5 (28) (2) (14) (1) SG&A expenses represent “Selling, general and administrative expenses”.

The amounts in respect of gains (losses) recognized in income for hedge ineffectiveness and amounts excluded from effectiveness testing were not significant for the three months ended March 31, 2016 and 2015, respectively. Net derivative losses of $1 million and $11 million, both net of tax, respectively, were reclassified from “Accumulated other comprehensive loss” to earnings during the three months ended March 31, 2016 and 2015, respectively. Fair value hedges To reduce its interest rate exposure arising primarily from its debt issuance activities, the Company uses interest rate swaps. Where such instruments are designated as fair value hedges, the changes in the fair value of these instruments, as well as the changes in the fair value of the risk component of the underlying debt being hedged, are recorded as offsetting gains and losses in “Interest and other finance expense”. Hedge ineffectiveness of instruments designated as fair value hedges for the three months ended March 31, 2016 and 2015, was not significant. The effect of Interest rate contracts, designated and qualifying as fair value hedges, on the Consolidated Income Statements was as follows: Three months ended March 31, ($ in millions) 2016 2015 Gains (losses) recognized in Interest and other finance expense: - on derivatives designated as fair value hedges 37 31 - on hedged item (37) (31) Derivatives not designated in hedge relationships Derivative instruments that are not designated as hedges or do not qualify as either cash flow or fair value hedges are economic hedges used for risk management purposes. Gains and losses from changes in the fair values of such derivatives are recognized in the same line in the income statement as the economically hedged transaction. Furthermore, under certain circumstances, the Company is required to split and account separately for foreign currency derivatives that are embedded within certain binding sales or purchase contracts denominated in a currency other than the functional currency of the subsidiary and the counterparty. The gains (losses) recognized in the Consolidated Income Statements on derivatives not designated in hedging relationships were as follows: Type of derivative not Gains (losses) recognized in income designated as a hedge Three months ended March 31, ($ in millions) Location 2016 2015 Foreign exchange contracts Total revenues 133 (78) Total cost of sales (61) (66) SG&A expenses(1) (12) 12 Non-order related research and development – (1) Interest and other finance expense (47) 177 Embedded foreign exchange contracts Total revenues (52) 27 Total cost of sales 6 (17) SG&A expenses(1) 3 – Commodity contracts Total cost of sales 2 (1) Other Interest and other finance expense – (1) Total (28) 52 (1) SG&A expenses represent “Selling, general and administrative expenses”.

Although the Company is party to close-out netting agreements with most derivative counterparties, the fair values in the tables above and in the Consolidated Balance Sheets at March 31, 2016, and December 31, 2015, have been presented on a gross basis. The Company’s netting agreements and other similar arrangements allow net settlements under certain conditions.

Note 5 Fair values The Company uses fair value measurement principles to record certain financial assets and liabilities on a recurring basis and, when necessary, to record certain non-financial assets at fair value on a non-recurring basis, as well as to determine fair value disclosures for certain financial instruments carried at amortized cost in the financial statements. Financial assets and liabilities recorded at fair value on a recurring basis include foreign currency, commodity and interest rate derivatives, as well as cash-settled call options and available-for-sale securities. Non-financial assets recorded at fair value on a non-recurring basis include long-lived assets that are reduced to their estimated fair value due to impairments. Fair value is the price that would be received when selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In determining fair value, the Company uses various valuation techniques including the market approach (using observable market data for identical or similar assets and liabilities), the income approach (discounted cash flow models) and the cost approach (using costs a market participant would incur to develop a comparable asset). Inputs used to determine the fair value of assets and liabilities are defined by a three-level hierarchy, depending on the reliability of those inputs. The Company has categorized its financial assets and liabilities and non-financial assets measured at fair value within this hierarchy based on whether the inputs to the valuation technique are observable or unobservable. An observable input is based on market data obtained from independent sources, while an unobservable input reflects the Company’s assumptions about market data. The levels of the fair value hierarchy are as follows: Level 1: Valuation inputs consist of quoted prices in an active market for identical assets or liabilities (observable quoted prices). Assets and liabilities valued using Level 1 inputs include listed derivatives which are actively traded such as commodity futures, interest rate futures and certain actively-traded debt securities. Level 2: Valuation inputs consist of observable inputs (other than Level 1 inputs) such as actively-quoted prices for similar assets, quoted prices in inactive markets and inputs other than quoted prices such as interest rate yield curves, credit spreads, or inputs derived from other observable data by interpolation, correlation, regression or other means. The adjustments applied to quoted prices or the inputs used in valuation models may be both observable and unobservable. In these cases, the fair value measurement is classified as Level 2 unless the unobservable portion of the adjustment or the unobservable input to the valuation model is significant, in which case the fair value measurement would be classified as Level 3. Assets and liabilities valued or disclosed using Level 2 inputs include investments in certain funds, reverse repurchase agreements, certain debt securities that are not actively traded, interest rate swaps, commodity swaps, cash-settled call options, forward foreign exchange contracts, foreign exchange swaps and forward rate agreements, time deposits, as well as financing receivables and debt. Level 3: Valuation inputs are based on the Company’s assumptions of relevant market data (unobservable input). Whenever quoted prices involve bid-ask spreads, the Company ordinarily determines fair values based on mid- market quotes. However, for the purpose of determining the fair value of cash-settled call options serving as hedges of the Company’s management incentive plan, bid prices are used. When determining fair values based on quoted prices in an active market, the Company considers if the level of transaction activity for the financial instrument has significantly decreased, or would not be considered orderly. In such cases, the resulting changes in valuation techniques would be disclosed. If the market is considered disorderly or if quoted prices are not available, the Company is required to use another valuation technique, such as an income approach. Recurring fair value measures The fair values of financial assets and liabilities measured at fair value on a recurring basis were as follows: March 31, 2016 ($ in millions) Level 1 Level 2 Level 3 Total fair value Assets Available-for-sale securities in “Cash and equivalents”: Debt securities—Corporate – 33 – 33 Available-for-sale securities in “Marketable securities and short-term investments”: Equity securities – 922 – 922 Debt securities—U.S. government obligations 123 – – 123 Debt securities—European government obligations 42 – – 42 Debt securities—Other government obligations – 2 – 2 Debt securities—Corporate – 344 – 344 Derivative assets—current in “Other current assets” 1 291 – 292 Derivative assets—non-current in “Other non-current assets” – 200 – 200 Total 166 1,792 – 1,958 Liabilities Derivative liabilities—current in “Other current liabilities” 1 295 – 296 Derivative liabilities—non-current in “Other non-current liabilities” – 107 – 107 Total 1 402 – 403

December 31, 2015 ($ in millions) Level 1 Level 2 Level 3 Total fair value Assets Available-for-sale securities in “Cash and equivalents”: Debt securities—Corporate – 11 – 11 Available-for-sale securities in “Marketable securities and short-term investments”: Equity securities – 667 – 667 Debt securities—U.S. government obligations 121 – – 121 Debt securities—Other government obligations – 2 – 2 Debt securities—Corporate – 508 – 508 Derivative assets—current in “Other current assets” 1 296 – 297 Derivative assets—non-current in “Other non-current assets” – 186 – 186 Total 122 1,670 – 1,792 Liabilities Derivative liabilities—current in “Other current liabilities” 3 315 – 318 Derivative liabilities—non-current in “Other non-current liabilities” – 134 – 134 Total 3 449 – 452 The Company uses the following methods and assumptions in estimating fair values of financial assets and liabilities measured at fair value on a recurring basis: - Available-for-sale securities in “Cash and equivalents” and “Marketable securities and short-term investments”: If quoted market prices in active markets for identical assets are available, these are considered Level 1 inputs; however, when markets are not active, these inputs are considered Level 2. If such quoted market prices are not available, fair value is determined using market prices for similar assets or present value techniques, applying an appropriate risk-free interest rate adjusted for nonperformance risk. The inputs used in present value techniques are observable and fall into the Level 2 category. - Derivatives: The fair values of derivative instruments are determined using quoted prices of identical instruments from an active market, if available (Level 1). If quoted prices are not available, price quotes for similar instruments, appropriately adjusted, or present value techniques, based on available market data, or option pricing models are used. Cash-settled call options hedging the Company’s WAR liability are valued based on bid prices of the equivalent listed warrant. The fair values obtained using price quotes for similar instruments or valuation techniques represent a Level 2 input unless significant unobservable inputs are used. Non-recurring fair value measures There were no significant non-recurring fair value measurements during the three months ended March 31, 2016 and 2015. Disclosure about financial instruments carried on a cost basis The fair values of financial instruments carried on a cost basis were as follows: March 31, 2016 ($ in millions) Carrying value Level 1 Level 2 Level 3 Total fair value Assets Cash and equivalents (excluding available-for-sale securities with original maturities up to 3 months): Cash 1,767 1,767 – – 1,767 Time deposits 2,166 – 2,166 – 2,166 Marketable securities and short-term investments (excluding available-for-sale securities): Time deposits 423 – 423 – 423 Receivables under reverse repurchase agreements 233 – 233 – 233 Other short-term investments 6 6 – – 6 Other non-current assets: Loans granted 30 – 31 – 31 Held-to-maturity securities 101 – 113 – 113 Restricted cash deposits 85 58 28 – 86 Liabilities Short-term debt and current maturities of long-term debt (excluding capital lease obligations) 1,546 631 915 – 1,546 Long-term debt (excluding capital lease obligations) 6,023 5,503 770 – 6,273 Non-current deposit liabilities in “Other non-current liabilities” 127 – 138 – 138

The carrying amounts of short-term debt and current maturities of long-term debt, excluding capital lease obligations, approximate their fair values. - Long-term debt (excluding capital lease obligations): Fair values of outstanding bonds are determined using quoted market prices (Level 1 inputs), if available. For other bonds and other long-term debt, the fair values are determined using a discounted cash flow methodology based upon borrowing rates of similar debt instruments and reflecting appropriate adjustments for non-performance risk (Level 2 inputs). - Non-current deposit liabilities in “Other non-current liabilities”: The fair values of non-current deposit liabilities are determined using a discounted cash flow methodology based on risk-adjusted interest rates (Level 2 inputs). Note 6 Commitments and contingencies Contingencies—Regulatory, Compliance and Legal Antitrust In April 2014, the European Commission announced its decision regarding its investigation of anticompetitive practices in the cables industry and granted the Company full immunity from fines under the European Commission’s leniency program. In December 2013, the Company agreed with the Brazilian Antitrust Authority (CADE) to settle its ongoing investigation into the Company’s involvement in anticompetitive practices in the cables industry and the Company agreed to pay a fine of approximately 1.5 million Brazilian reals (equivalent to approximately $1 million on date of payment). In Brazil, the Company’s Gas Insulated Switchgear business is under investigation by the CADE for alleged anticompetitive practices. In addition, the CADE has opened an investigation into certain other power businesses of the Company, including flexible alternating current transmission systems (FACTS) and power transformers. With respect to these matters, management is cooperating fully with the authorities. An informed judgment about the outcome of these investigations or the amount of potential loss or range of loss for the Company, if any, relating to these investigations cannot be made at this stage. General In addition, the Company is aware of proceedings, or the threat of proceedings, against it and others in respect of private claims by customers and other third parties with regard to certain actual or alleged anticompetitive practices. Also, the Company is subject to other various legal proceedings, investigations, and claims that have not yet been resolved. With respect to the above mentioned regulatory matters and commercial litigation contingencies, the Company will bear the costs of the continuing investigations and any related legal proceedings. Liabilities recognized At March 31, 2016, and December 31, 2015, the Company had aggregate liabilities of $165 million and $160 million, respectively, included in “Other provisions” and “Other non-current liabilities”, for the above regulatory, compliance and legal contingencies, and none of the individual liabilities recognized was significant. As it is not possible to make an informed judgment on the outcome of certain matters and as it is not possible, based on information currently available to management, to estimate the maximum potential liability on other matters, there could be material adverse outcomes beyond the amounts accrued.

Guarantees General The following table provides quantitative data regarding the Company’s third-party guarantees. The maximum potential payments represent a “worst-case scenario”, and do not reflect management’s expected outcomes. Maximum potential payments ($ in millions) March 31, 2016 December 31, 2015 Performance guarantees 202 209 Financial guarantees 78 77 Indemnification guarantees 50 50 Total 330 336 The carrying amount of liabilities recorded in the Consolidated Balance Sheets reflects the Company’s best estimate of future payments, which it may incur as part of fulfilling its guarantee obligations. In respect of the above guarantees, the carrying amounts of liabilities at March 31, 2016, and December 31, 2015, were not significant. The Company is party to various guarantees providing financial or performance assurances to certain third-parties. These guarantees, which have various maturities up to 2020, mainly consist of performance guarantees whereby (i) the Company guarantees the performance of a third party’s product or service according to the terms of a contract and (ii) as member of a consortium that includes third parties, the Company guarantees not only its own performance but also the work of third parties. Such guarantees may include guarantees that a project will be completed within a specified time. If the third party does not fulfill the obligation, the Company will compensate the guaranteed party in cash or in kind. The original maturity dates for the majority of these performance guarantees range from one to six years. Commercial commitments In addition, in the normal course of bidding for and executing certain projects, the Company has entered into standby letters of credit, bid/performance bonds and surety bonds (collectively “performance bonds”) with various financial institutions. Customers can draw on such performance bonds in the event that the Company does not fulfill its contractual obligations. The Company would then have an obligation to reimburse the financial institution for amounts paid under the performance bonds. At March 31, 2016 and December 31, 2015 the total outstanding performance bonds aggregated to $8.9 billion and $9.5 billion, respectively. There have been no significant amounts reimbursed to financial institutions under these types of arrangements in the three months ended March 31, 2016 and 2015. Product and order-related contingencies The Company calculates its provision for product warranties based on historical claims experience and specific review of certain contracts. The reconciliation of the “Provisions for warranties”, including guarantees of product performance, was as follows: ($ in millions) 2016 2015 Balance at January 1, 1,089 1,148 Claims paid in cash or in kind (61) (70) Net increase in provision for changes in estimates, warranties issued and warranties expired 61 45 Exchange rate differences 32 (60) Balance at March 31, 1,121 1,063 Note 7 Employee benefits The Company operates defined benefit pension plans, defined contribution pension plans, and termination indemnity plans, in accordance with local regulations and practices. These plans cover a large portion of the Company’s employees and provide benefits to employees in the event of death, disability, retirement, or termination of employment. Certain of these plans are multi-employer plans. The Company also operates other postretirement benefit plans including postretirement health care benefits, and other employee-related benefits for active employees including long-service award plans. The measurement date used for the Company’s employee benefit plans is December 31. The funding policies of the Company’s plans are consistent with the local government and tax requirements. Net periodic benefit cost of the Company’s defined benefit pension and other postretirement benefit plans consisted of the following: Defined pension Other postretirement ($ in millions) benefits benefits Three months ended March 31, 2016 2015 2016 2015 Service cost 63 66 – – Interest cost 71 75 2 2 Expected return on plan assets (102) (113) – – Amortization of prior service cost (credit) 10 9 (3) (2) Amortization of net actuarial loss 22 28 – – Net periodic benefit cost 64 65 (1) –

Employer contributions were as follows: Defined pension Other postretirement ($ in millions) benefits benefits Three months ended March 31, 2016 2015 2016 2015 Total contributions to defined benefit pension and other postretirement benefit plans 52 49 3 4 The Company expects to make contributions totaling approximately $255 million and $15 million to its defined benefit pension plans and other postretirement benefit plans, respectively, for the full year 2016. Note 8 Stockholders’ equity In September 2014, the Company announced a share buyback program for the purchase of up to $4 billion of its own shares over a period ending no later than September 2016. The Company intends that approximately three quarters of the shares to be purchased will be held for cancellation (after approval from shareholders) and the remainder will be purchased to be available for delivery to employees under its employee share programs. Shares acquired for cancellation are acquired through a separate trading line on the SIX Swiss Exchange (on which only the Company can purchase shares), while shares acquired for delivery under employee share programs are acquired through the ordinary trading line. In the three months ended March 31, 2016, under the announced share buyback program, the Company purchased 24.630 million shares for cancellation and 3.040 million shares to support its employee share programs. These transactions resulted in an increase in Treasury stock of $496 million. In the three months ended March 31, 2015, under the announced share buyback program, the Company purchased 17.380 million shares for cancellation and 4.125 million shares to support its employee share programs. These transactions resulted in an increase in Treasury stock of $452 million. As of March 31, 2016, under this program, the Company has purchased a total of 110.855 million shares for cancellation and 22.840 million shares to support its employee share programs. Note 9 Earnings per share Basic earnings per share is calculated by dividing income by the weighted-average number of shares outstanding during the period. Diluted earnings per share is calculated by dividing income by the weighted-average number of shares outstanding during the period, assuming that all potentially dilutive securities were exercised, if dilutive. Potentially dilutive securities comprise outstanding written call options and outstanding options and shares granted subject to certain conditions under the Company’s share-based payment arrangements.

Note 11 Restructuring and related expenses White Collar Productivity program In September 2015, the Company announced a two-year program aimed at making the Company leaner, faster and more customer-focused. Planned productivity improvements include the rapid expansion and use of regional shared service centers as well as the streamlining of global operations and head office functions, with business units moving closer to their respective key markets. In the course of this program, the Company will implement and execute various restructuring initiatives across all operating segments and regions. The following table outlines the costs incurred in the three months ended March 31, 2016, the cumulative costs incurred to date and the total amount of costs expected to be incurred under the program per operating segment: Costs incurred in the Cumulative costs three months ended incurred up to ($ in millions) March 31, 2016 March 31, 2016 Total expected costs(1) Electrification Products 1 74 175 Discrete Automation and Motion – 45 169 Process Automation – 96 148 Power Grids (1) 69 177 Corporate and Other (1) 85 183 Total (1) 369 852 (1) Total expected costs have been recast to reflect the reorganization of the Company’s operating segments as outlined in Note 12.

These expenses mainly related to employee severance costs and were primarily recorded in “Total cost of sales”.

Note 12 Operating segment data The Chief Operating Decision Maker (CODM) is the Company’s Executive Committee. The CODM allocates resources to and assesses the performance of each operating segment using the information outlined below. The Company’s operating segments consist of Electrification Products, Discrete Automation and Motion, Process Automation and Power Grids. The remaining operations of the Company are included in Corporate and Other. Effective January 1, 2016, the Company reorganized its operating segments with the aim of delivering more customer value in a better, more focused way from its combined power and automation offering. The new Electrification Products segment includes the business of the former Low Voltage Products segment and the Medium Voltage Products business from the former Power Products segment. The Process Automation segment has been expanded to include the Distributed Control Systems business from the former Power Systems segment, while the remaining businesses of the former Power Products and Power Systems segments were combined to form the new Power Grids segment. There were no significant changes to the Discrete Automation and Motion segment. In addition, commencing in 2016, the Company changed its method of allocating income taxes to its operating segments whereby tax assets are primarily accounted for in Corporate and Other. As a result, certain amounts relating to current and deferred tax assets previously reported within the total segment assets of each individual operating segment have been allocated to Corporate and Other. The segment information for the three months ended March 31, 2015 and at December 31, 2015, has been recast to reflect these organizational and allocation changes. A description of the types of products and services provided by each reportable segment is as follows: - Electrification Products: manufactures and sells products and services including low- and medium-voltage switchgear (air and gas insulated), breakers, switches, control products, DIN rail components, automation and distribution enclosures, wiring accessories and installation material for many kinds of applications. - Discrete Automation and Motion: manufactures and sells motors, generators, variable speed drives, programmable logic controllers, robots and robotics, solar inverters, wind converters, rectifiers, excitation systems, power quality and protection solutions, electric vehicle fast charging infrastructure, components and subsystems for railways, and related services for a wide range of applications in discrete automation, process industries, transportation and utilities. - Process Automation: develops and sells control and plant optimization systems, automation products and solutions, including instrumentation, as well as industry-specific application knowledge and services for the oil, gas and petrochemicals, metals and minerals, marine and turbocharging, pulp and paper, chemical and pharmaceuticals, and power industries. - Power Grids: supplies power and automation products, systems, and service and software solutions for power generation, transmission and distribution to utility, industry, transportation and infrastructure customers. These offerings address evolving grid developments which include the integration of renewables, network control, digital substations, microgrids and asset management. The segment also manufactures a wide range of power, distribution and traction transformers, an array of high-voltage products, including circuit breakers, switchgear, capacitors and power transmission systems. - Corporate and Other: includes headquarters, central research and development, the Company’s real estate activities, Group Treasury Operations, historical operating activities of certain divested businesses, and other minor business activities. The Company evaluates the profitability of its segments based on Operational EBITA, which represents income from operations excluding amortization expense on intangibles arising upon acquisitions (acquisition-related amortization), restructuring and restructuring-related expenses, gains and losses from sale of businesses, acquisition-related expenses and certain non-operational items, as well as foreign exchange/commodity timing differences in income from operations consisting of: (i) unrealized gains and losses on derivatives (foreign exchange, commodities, embedded derivatives), (ii) realized gains and losses on derivatives where the underlying hedged transaction has not yet been realized, and (iii) unrealized foreign exchange movements on receivables/payables (and related assets/liabilities). The CODM primarily reviews the results of each segment on a basis that is before the elimination of profits made on inventory sales between segments. Segment results below are presented before these eliminations, with a total deduction for intersegment profits to arrive at the Company’s consolidated Operational EBITA. Intersegment sales and transfers are accounted for as if the sales and transfers were to third parties, at current market prices.

The following tables present segment revenues, Operational EBITA, and the reconciliations of consolidated Operational EBITA to Income from continuing operations before taxes for the three months ended March 31, 2016 and 2015, as well as total assets at March 31, 2016, and December 31, 2015.

Supplemental Reconciliations and Definitions The following reconciliations and definitions include measures which ABB uses to supplement its Interim Consolidated Financial Information (unaudited) which is prepared in accordance with United States generally accepted accounting principles (U.S. GAAP). Certain of these financial measures are, or may be, considered non- GAAP financial measures as defined in the rules of the U.S. Securities and Exchange Commission (SEC). While ABB’s management believes that the non-GAAP financial measures herein are useful in evaluating ABB’s operating results, this information should be considered as supplemental in nature and not as a substitute for the related financial information prepared in accordance with U.S. GAAP. Therefore these measures should not be viewed in isolation but considered together with the Interim Consolidated Financial Information (unaudited) prepared in accordance with U.S. GAAP as of and for the three months ended March 31, 2016. Comparable growth rates Growth rates for certain key figures may be presented and discussed on a “comparable” basis. The comparable growth rate measures growth on a constant currency basis. Since we are a global company, the comparability of our operating results reported in U.S. dollars is affected by foreign currency exchange rate fluctuations. We calculate the impacts from foreign currency fluctuations by translating the current-year periods’ reported key figures into U.S. dollar amounts using the exchange rates in effect for the comparable periods in the previous year. Comparable growth rates also adjust for changes in our business portfolio. Adjustments to our business portfolio occur due to acquisitions, divestments, or by exiting specific business activities or customer markets. The adjustment for portfolio changes is calculated as follows: where the results of any business acquired or divested have not been consolidated and reported for the entire duration of both the current and comparable periods, the reported key figures of such business are adjusted to exclude the relevant key figures of any corresponding quarters which are not comparable when computing the comparable growth rate. Certain portfolio changes which do not qualify as divestments under U.S. Generally Accepted Accounting Principles have been treated in a similar manner to divestments. Changes in our portfolio where we have exited certain business activities or customer markets are adjusted as if the relevant business was divested in the period when the decision to cease business activities was taken. We do not adjust for portfolio changes where the relevant business has annualized revenues of less than $50 million. The following tables provide reconciliations of reported growth rates of certain key figures to their respective comparable growth rate.

Our new streamlined structure is comprised of four operating divisions: Power Grids, Electrification Products, Discrete Automation and Motion and Process Automation. In addition, the operations of certain previously divested businesses have been excluded from the results of the four divisions (but are included in the total ABB Group) for the periods prior to their respective divestment. Please see Note 12 to the Interim Consolidated Financial Information (unaudited) for further details on the realignment.

Operational EBITA margin Definition Operational EBITA margin Operational EBITA margin is Operational EBITA as a percentage of Operational revenues. Operational EBITA Operational earnings before interest, taxes and acquisition-related amortization (Operational EBITA) represents Income from operations excluding acquisition-related amortization (as defined below), restructuring and restructuring- related expenses, gains and losses from sale of businesses, acquisition-related expenses and certain non- operational items, as well as foreign exchange/commodity timing differences in income from operations consisting of: (i) unrealized gains and losses on derivatives (foreign exchange, commodities, embedded derivatives), (ii) realized gains and losses on derivatives where the underlying hedged transaction has not yet been realized, and (iii) unrealized foreign exchange movements on receivables/payables (and related assets/liabilities). Acquisition-related amortization Amortization expense on intangibles arising upon acquisitions. Operational revenues Operational revenues are total revenues adjusted for foreign exchange/commodity timing differences in total revenues of: (i) unrealized gains and losses on derivatives, (ii) realized gains and losses on derivatives where the underlying hedged transaction has not yet been realized, and (iii) unrealized foreign exchange movements on receivables (and related assets).

Operational EPS Definition Operational EPS Operational EPS is calculated as Operational net income divided by the weighted-average number of shares used in determining basic earnings per share. Operational net income Operational net income is calculated as Net income attributable to ABB adjusted for the net-of-tax impact of: (i) restructuring and restructuring-related expenses, (ii) gains and losses from sale of businesses, acquisition-related expenses and certain non-operational items, (iii) foreign exchange/commodity timing differences in income from operations consisting of: (a) unrealized gains and losses on derivatives (foreign exchange, commodities, embedded derivatives), (b) realized gains and losses on derivatives where the underlying hedged transaction has not yet been realized, and (c) unrealized foreign exchange movements on receivables/payables (and related assets/liabilities), and (iv) acquisition-related amortization. Acquisition-related amortization Amortization expense on intangibles arising upon acquisitions. Adjusted Group effective tax rate The Adjusted Group effective tax rate is computed by dividing an adjusted provision for taxes by an adjusted income from continuing operations before taxes. Certain amounts recorded in income from continuing operations before taxes and the related provision for taxes (primarily gains and losses from sale of businesses), as well as certain other amounts included solely in provision for taxes, are excluded from the computation. Constant currency Operational EPS adjustment and Operational EPS growth rate (constant currency) In connection with ABB’s 2015-2020 targets, Operational EPS growth is measured assuming 2014 as the base year and uses constant exchange rates. We compute the constant currency operational net income for all periods using the relevant monthly exchange rates which were in effect during 2014 and any difference in computed Operational net income is divided by the relevant weighted-average number of shares outstanding to identify the constant currency Operational EPS adjustment.
