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 company in power and automation technologies that enable utility and industry 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, 2014. 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, 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 in the Consolidated Statements of Cash Flows reported for prior periods in the Interim Consolidated Financial Information have been reclassified to conform to the current period presentation. These reclassifications were within Net cash provided by operating activities. R Note 2 Recent accounting pronouncements Applicable for future periods evenue 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. The update is effective for the Company for annual and interim periods beginning January 1, 2017, 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). The Company is currently evaluating the impact of this update on its consolidated financial statements.

Simplifying the presentation of debt issuance costs In April 2015, an accounting standard update was issued to simplify the presentation of debt issuance costs. Under the update, the Company would present debt issuance costs related to a recognized debt liability in the balance sheet as a direct deduction from the carrying amount of that debt liability rather than as a non-current asset. The existing recognition and measurement guidance for debt issuance costs is not affected by this accounting standard update which is effective for the Company for annual and interim periods beginning January 1, 2016, and is applicable retrospectively. Early adoption is permitted for financial statements that have not been previously issued. The Company does not believe that this update will have a material impact on its consolidated financial statements. Cash and equivalents, marketable securities and short-term investments consisted of the following: March 31, 2015 ($ in millions) Cost basis Gross unrealized gains Gross unrealized losses Fair value Cash and equivalents Marketable securities and short-term investments Cash 1,617 1,617 1,617 – Time deposits 3,189 3,189 2,768 421 Other short-term investments 227 227 – 227 Debt securities available-for-sale: U.S. government obligations 135 3 (1) 137 – 137 Other government obligations 2 – – 2 – 2 Corporate 658 4 – 662 86 576 Equity securities available-for-sale 308 13 – 321 – 321 Total6,13620(1)6,1554,4711,684 December 31, 2014 ($ in millions) Cost basis Gross unrealized gains Gross unrealized losses Fair value Cash and equivalents Marketable securities and short-term investments Cash 2,218 2,218 2,218 – Time deposits 3,340 3,340 3,140 200 Other short-term investments 225 225 – 225 Debt securities available-for-sale: U.S. government obligations 135 2 (1) 136 – 136 Other government obligations 2 – – 2 – 2 Corporate 734 4 (1) 737 85 652 Equity securities available-for-sale 98 12 – 110 – 110 Total 6,75218(2)6,7685,4431,325 Included in Other short-term investments at March 31, 2015, and December 31, 2014, are receivables of $220 million and $219 million, respectively, representing reverse repurchase agreements. These collateralized lendings, made to a financial institution, have maturity dates of less than one year. Non-current assets Included in “Other non-current assets” are certain held-to-maturity marketable securities. At March 31, 2015, the amortized cost, gross unrecognized gain and fair value (based on quoted market prices) of these securities were $86 million, $25 million and $111 million, respectively. At December 31, 2014, the amortized cost, gross unrecognized gain and fair value (based on quoted market prices) of these securities were $95 million, $14 million and $109 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 riskDue 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. 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 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 ($ in millions) March 31, 2015 December 31, 2014 March 31, 2014 Foreign exchange contracts 17,871 18,564 19,060 Embedded foreign exchange derivatives 2,972 3,013 2,958 Interest rate contracts 4,057 2,242 6,702 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 March 31, 2015 December 31, 2014 March 31, 2014 Copper swaps metric tonnes 53,237 46,520 43,866 Aluminum swaps metric tonnes 5,225 3,846 3,873 Nickel swaps metric tonnes – – 12 Lead swaps metric tonnes 14,325 6,550 5,175 Zinc swaps metric tonnes 125 200 275 Silver swaps ounces 1,707,460 1,996,845 1,813,511 Crude oil swaps barrels 150,700 128,000 142,000 Equity derivatives At March 31, 2015, December 31, 2014, and March 31, 2014, the Company held 59 million, 61 million and 66 million cash-settled call options indexed to ABB Ltd shares (conversion ratio 5:1) with a total fair value of $26 million, $33 million and $50 million, respectively.

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, 2015, and December 31, 2014, “Accumulated other comprehensive loss” included net unrealized losses of $32 million and $21 million, respectively, net of tax, on derivatives designated as cash flow hedges. Of the amount at March 31, 2015, net losses of $22 million are expected to be reclassified to earnings in the following 12 months. At March 31, 2015, the longest maturity of a derivative classified as a cash flow hedge was 54 months. The amount of gains or losses, net of tax, reclassified into earnings due to the discontinuance of cash flow hedge accounting and the amount of ineffectiveness in cash flow hedge relationships directly recognized in earnings were not significant in the three months ended March 31, 2015 and 2014. The pre-tax effects of derivative instruments, designated and qualifying as cash flow hedges, on “Accumulated other comprehensive loss” (OCI) and the Consolidated Income Statements were as follows: Three months ended March 31, 2015 Type of derivative designated as a cash flow hedge Gains (losses) recognized in OCI on derivatives (effective portion) Gains (losses) reclassified from OCI into income (effective portion) Gains (losses) recognized in income ( ineffective portion and amount excluded from effectiveness testing) ($ in millions) Location ($ in millions) Location ($ in millions) Foreign exchange contracts (22) Total revenues (13) Total revenues – Total cost of sales 5 Total cost of sales – Commodity contracts (2) Total cost of sales (3) Total cost of sales – Cash-settled call options (4) SG&A expenses (1) (3) SG&A expenses (1) – Total (28)(14)– Three months ended March 31, 2014 Type of derivative designated as a cash flow hedge Gains (losses) recognized in OCI on derivatives (effective portion) Gains (losses) reclassified from OCI into income (effective portion) Gains (losses) recognized in income ( ineffective portion and amount excluded from effectiveness testing) ($ in millions) Location ($ in millions) Location ($ in millions) Foreign exchange contracts (6) Total revenues 1 Total revenues – Total cost of sales 3 Total cost of sales – Commodity contracts (4) Total cost of sales (1) Total cost of sales – Cash-settled call options (4) SG&A expenses (1) (1) SG&A expenses (1) – Total(14)2– (1)SG&A expenses represent “Selling, general and administrative expenses”. Net derivative losses of $11 million and net derivative gains of $1 million, both net of tax, respectively, were reclassified from “Accumulated other comprehensive loss” to earnings during the three months ended March 31, 2015 and 2014, 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, 2015 and 2014, was not significant. The effect of derivative instruments, designated and qualifying as fair value hedges, on the Consolidated Income Statements was as follows: Three months ended March 31, 2015 Type of derivative designated as a fair value hedge Gains (losses) recognized in income on derivatives designated as fair value hedges Gains (losses) recognized in income on hedged item Location ($ in millions) Location ($ in millions) Interest rate contracts Interest and other finance expense 31 Interest and other finance expense (31) Three months ended March 31, 2014 Type of derivative designated as a fair value hedge Gains (losses) recognized in income on derivatives designated as fair value hedges Gains (losses) recognized in income on hedged item Location ($ in millions) Location ($ in millions) Interest rate contracts Interest and other finance expense 22 Interest and other finance expense (22) 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 designated as a hedge Gains (losses) recognized in income Three months ended March 31, ($ in millions) Location 2015 2014 Foreign exchange contracts Total revenues (78) (23) Total cost of sales (66) (10) SG&A expenses (1) 12 1 Interest and other finance expense 177 4 Non-order related research and development (1) – Embedded foreign exchange contracts Total revenues 27 10 Total cost of sales (17) – Commodity contracts Total cost of sales (1) (22) Interest rate contracts Interest and other finance expense (1) – Total 52 (40) (1)SG&A expenses represent “Selling, general and administrative expenses”.

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.

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 measuresThere were no significant non-recurring fair value measurements during the three months ended March 31, 2015 and 2014.

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, 2015 ($ 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 1,617 1,617 – – 1,617 Time deposits 2,768 – 2,768 – 2,768 Marketable securities and short-term investments (excluding available-for-sale securities): Time deposits 421 – 421 – 421 Receivables under reverse repurchase agreements 220 – 220 – 220 Other short-term investments 7 7 – – 7 Other non-current assets: Loans granted 38 – 41 – 41 Held-to-maturity securities 86 – 111 – 111 Restricted cash deposits 182 60 137 – 197 Liabilities Short-term debt and current maturities of long-term debt (excluding capital lease obligations) 473 107 366 – 473 Long-term debt (excluding capital lease obligations) 7,097 6,004 1,428 – 7,432 Non-current deposit liabilities in “Other non-current liabilities” 206 – 245 – 245 December 31, 2014 ($ 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 2,218 2,218 – – 2,218 Time deposits 3,140 – 3,140 – 3,140 Marketable securities and short-term investments (excluding available-for-sale securities): Time deposits 200 – 200 – 200 Receivables under reverse repurchase agreements 219 – 219 – 219 Other short-term investments 6 6 – – 6 Other non-current assets: Loans granted 41 – 44 – 44 Held-to-maturity securities 95 – 109 – 109 Restricted cash deposits 198 64 161 – 225 Liabilities Short-term debt and current maturities of long-term debt (excluding capital lease obligations) 324 115 209 – 324 Long-term debt (excluding capital lease obligations) 7,224 6,148 1,404 – 7,552 Non-current deposit liabilities in “Other non-current liabilities” 222 – 267 – 267 Note 5 Fair values, continued

The Company uses the following methods and assumptions in estimating fair values of financial instruments carried on a cost basis: – Cash and equivalents (excluding available-for-sale securities with original maturities up to 3 months), and Marketable securities and short-term investments (excluding available-for-sale securities): The carrying amounts approximate the fair values as the items are short-term in nature. – Other non-current assets: Includes (i) loans granted whose fair values are based on the carrying amount adjusted using a present value technique to reflect a premium or discount based on current market interest rates (Level 2 inputs), (ii) held-to-maturity securities (see Note 3) whose fair values are based on quoted market prices in inactive markets (Level 2 inputs), (iii) restricted cash whose fair values approximate the carrying amounts (Level 1 inputs) and restricted cash deposits pledged in respect of certain non-current deposit liabilities whose fair values are determined using a discounted cash flow methodology based on current market interest rates (Level 2 inputs). – Short-term debt and current maturities of long-term debt (excluding capital lease obligations): Includes commercial paper, bank borrowings and overdrafts. 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—Environmental The Company is engaged in environmental clean-up activities at certain sites arising under various United States and other environmental protection laws and under certain agreements with third parties. In some cases, these environmental remediation actions are subject to legal proceedings, investigations or claims, and it is uncertain to what extent the Company is actually obligated to perform. Provisions for these unresolved matters have been set up if it is probable that the Company has incurred a liability and the amount of loss can be reasonably estimated. The lower end of an estimated range is accrued when a single best estimate is not determinable. The required amounts of the provisions may change in the future as developments occur. If a provision has been recognized for any of these matters, the Company records an asset when it is probable that it will recover a portion of the costs expected to be incurred to settle them. Management is of the opinion, based upon information presently available, that the resolution of any such obligation and non-collection of recoverable costs would not have a further material adverse effect on the Company’s consolidated financial statements. The Company is involved in the remediation of environmental contamination at present or former facilities, primarily in the United States. The clean-up of these sites involves primarily soil and groundwater contamination. A significant portion of the provisions in respect of these contingencies reflects the provisions of acquired companies. A portion of one of the acquired companies’ remediation liability is indemnified by a prior owner. Accordingly, an asset equal to that portion of the remediation liability is included in “Other non-current assets”. Environmental provisions included in the Company’s Consolidated Balance Sheets were as follows: ($ in millions) March 31, 2015 December 31, 2014 Other provisions 29 37 Other non-current liabilities 108 109 Total 137 146 Provisions for the above estimated losses have not been discounted as the timing of payments cannot be reasonably estimated. 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). The Company’s cables business remains under investigation for alleged anticompetitive practices in certain other jurisdictions. An informed judgment about the outcome of these remaining investigations or the amount of potential loss or range of loss for the Company, if any, relating to these remaining investigations cannot be made at this stage. 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. 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. With respect to those aforementioned matters which are still ongoing, management is cooperating fully with the antitrust authorities. Note 5 Fair values, continued 21 Q1 2015 Financial Information

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, 2015, and December 31, 2014, the Company had aggregate liabilities of $144 million and $147 million, respectively, included in “Other provisions” and “Other non-current liabilities”, for the above regulatory, compliance and legal contingencies, and none of the individual liabilities recognized was significant. As it is not possible to make an informed judgment on the outcome of certain matters and as it is not possible, based on information currently available to management, to estimate the maximum potential liability on other matters, there could be material adverse outcomes beyond the amounts accrued. Guarantees General The following table provides quantitative data regarding the Company’s third-party guarantees. The maximum potential payments represent a “worst-case scenario”, and do not reflect management’s expected outcomes. Maximum potential payments ($ in millions) March 31, 2015 December 31, 2014 Performance guarantees 230 232 Financial guarantees 74 72 Indemnification guarantees 50 50 Total 354 354 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, 2015, and December 31, 2014, were not significant. Performance guarantees Performance guarantees represent obligations where the Company guarantees the performance of a third party’s product or service according to the terms of a contract. 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. Performance guarantees include surety bonds, advance payment guarantees and standby letters of credit. The significant performance guarantees are described below. The Company retained obligations for guarantees related to the Power Generation business contributed in mid-1999 to the former ABB Alstom Power NV joint venture (Alstom Power NV). The guarantees primarily consist of performance guarantees and other miscellaneous guarantees under certain contracts such as indemnification for personal injuries and property damages, taxes and compliance with labor laws, environmental laws and patents. These guarantees have no fixed expiration date. In May 2000, the Company sold its interest in Alstom Power NV to Alstom SA (Alstom). As a result, Alstom and its subsidiaries have primary responsibility for performing the obligations that are the subject of the guarantees. Further, Alstom, the parent company and Alstom Power NV, have undertaken jointly and severally to fully indemnify and hold harmless the Company against any claims arising under such guarantees. Management’s best estimate of the total maximum potential amount payable of quantifiable guarantees issued by the Company on behalf of its former Power Generation business was $65 million at both March 31, 2015, and December 31, 2014. The Company has not experienced any losses related to guarantees issued on behalf of the former Power Generation business. The Company is engaged in executing a number of projects as a member of consortia that include third parties. In certain of these cases, the Company guarantees not only its own performance but also the work of third parties. The original maturity dates of these guarantees range from one to six years. At both March 31, 2015, and December 31, 2014, the maximum potential amount payable under these guarantees as a result of third-party non-performance was $156 million. Financial guarantees and commercial commitments Financial guarantees represent irrevocable assurances that the Company will make payment to a beneficiary in the event that a third party fails to fulfill its financial obligations and the beneficiary under the guarantee incurs a loss due to that failure. At March 31, 2015, and December 31, 2014, the Company had a maximum potential amount payable of $74 million and $72 million, respectively, under financial guarantees outstanding. Of these amounts, $12 million at both March 31, 2015, and December 31, 2014, was in respect of guarantees issued on behalf of companies in which the Company formerly had or has an equity interest. The guarantees outstanding have various maturity dates up to 2020. 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. There have been no significant amounts reimbursed to financial institutions under these types of arrangements in the three months ended March 31, 2015 and 2014.

Note 6 Commitments and contingencies, continued Indemnification guarantees The Company has indemnified certain purchasers of divested businesses for potential claims arising from the operations of the divested businesses. To the extent the maximum potential loss related to such indemnifications could not be calculated, no amounts have been included under maximum potential payments in the table above. Indemnifications for which maximum potential losses could not be calculated include indemnifications for legal claims. The significant indemnification guarantees for which maximum potential losses could be calculated are described below. The Company issued to the purchasers of Lummus Global guarantees related to assets and liabilities divested in 2007. The maximum potential amount payable relating to this business, pursuant to the sales agreement, at each of March 31, 2015, and December 31, 2014, was $50 million. Product and order-related contingencies The Company calculates its provision for product warranties based on historical claims experience and specific review of certain contracts. The reconciliation of the “Provisions for warranties”, including guarantees of product performance, was as follows: ($ in millions) 2015 2014 Balance at January 1, 1,148 1,362 Claims paid in cash or in kind (70) (79) Net increase in provision for changes in estimates, warranties issued and warranties expired 45 29 Exchange rate differences (60) (5) Balance at March 31,1,0631,307 Note 7 Employee benefits The Company operates defined benefit and 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 and several of the plans are not required to be funded according to 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: ($ in millions) Defined pension benefits Other postretirement benefits Three months ended March 31,2015 2014 2015 2014 Service cost 66 64 – – Interest cost 75 105 2 2 Expected return on plan assets (113) (124) – – Amortization of prior service cost (credit) 9 7 (2) (2) Amortization of net actuarial loss 28 26 – – Net periodic benefit cost 6578–– Employer contributions were as follows: ($ in millions) Defined pension benefits Other postretirement benefits Three months ended March 31, 2015 2014 2015 2014 Total contributions to defined benefit pension and other postretirement benefit plans 49 131 4 3 Of which, discretionary contributions to defined benefit pension plans – 75 – – During the three months ended March 31, 2014, discretionary contributions included available-for-sale debt securities, having a fair value at the contribution date of $25 million, to certain of the Company’s pension plans in the United Kingdom. The Company expects to make contributions totaling approximately $220 million and $17 million to its defined benefit pension plans and other postretirement benefit plans, respectively, for the full year 2015. 21 Q1 2015 Financial Information

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, 2015, under the announced share buyback program, the Company purchased 17.4 million shares for cancellation and 4.1 million shares to support its employee share programs. These transactions resulted in an increase in “Treasury stock” of $452 million. As of March 31, 2015, under this program, the Company has purchased a total of approximately 43 million shares for cancellation and approximately 11 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 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 Discrete Automation and Motion, Low Voltage Products, Process Automation, Power Products and Power Systems. The remaining operations of the Company are included in Corporate and Other. A description of the types of products and services provided by each reportable segment is as follows: – 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. – Low Voltage Products: manufactures and sells products and systems that provide protection, control and measurement for electrical installations, as well as enclosures, switchboards, electronics and electromechanical devices for industrial machines, plants and related service. In addition, the segment manufactures products for wiring and cable management, cable protection systems, power connection and safety. The segment also makes intelligent building control systems for home and building automation. – 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 Products: manufactures and sells a wide range of products across voltage levels, including circuit breakers, switchgears, capacitors, instrument transformers, power, distribution and traction transformers for electrical and other infrastructure utilities, as well as industrial and commercial customers. – Power Systems: designs, installs and upgrades high-efficiency transmission and distribution systems and power plant automation and electrification solutions, including monitoring and control products, software and services and incorporating components manufactured by both the Company and by third parties, for power generation, transmission and distribution utilities, other infrastructure utilities, as well as other industrial and commercial enterprises. – Corporate and Other: includes headquarters, central research and development, the Company’s real estate activities, Group Treasury Operations and other minor business activities. Effective January 1, 2015, the Company changed its primary measure of segment performance from Operational EBITDA to 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 segment performance for the three months ended March 31, 2014, has been restated to reflect this change. 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, 2015 and 2014, as well as total assets at March 31, 2015, and December 31, 2014.

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, 2015. Like-for-like growth rates Growth rates for certain key figures may be presented and discussed on a “like-for-like” basis. The like-for-like 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. Like-for-like growth rates also adjust for changes in our business portfolio. 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 like- for-like growth rate. In addition, certain other adjustments, which affect the business portfolio but do not qualify as a divestment, are treated in a similar manner to a divestment. We do not adjust for portfolio changes where the business acquired or divested has annual revenues of less than $50 million. The following tables provide reconciliations of reported growth of certain key figures to their respective like-for-like growth rate.

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 the provision for income taxes by income from continuing operations before taxes. The calculation excludes the amount of gains and losses from sale of businesses and the related provision for income taxes. Constant currency Operational EPS adjustment 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 income difference is divided by the relevant weighted-average number of shares outstanding to identify the constant currency Operational EPS adjustment.

Net debt / (Net cash)Definition Net debt / (Net cash) Net debt / (Net cash) is defined as Total debt less Cash and marketable securities. Total debt Total debt is the sum of Short-term debt and current maturities of long-term debt, and Long-term debt. Cash and marketable securities Cash and marketable securities is the sum of Cash and equivalents, and Marketable securities and short-term investments.

Net working capital as a percentage of revenues Definition Net working capital as a percentage of revenues Net working capital as a percentage of revenues is calculated as Net working capital divided by Adjusted revenues for the trailing twelve months. Net working capital Net working capital is the sum of (i) receivables, net, (ii) inventories, net, and (iii) prepaid expenses; less (iv) accounts payable, trade, (v) billings in excess of sales, (vi) advances from customers, and (vii) other current liabilities (excluding primarily: (a) income taxes payable, (b) current derivative liabilities, (c) pension and other employee benefits, and (d) payables under the share buyback program); and including the amounts related to these accounts which have been presented as either assets or liabilities held for sale. Adjusted revenues for the trailing twelve months Adjusted revenues for the trailing twelve months includes total revenues recorded by ABB in the twelve months preceding the relevant balance sheet date adjusted to eliminate revenues of divested businesses and the estimated impact of annualizing revenues of certain acquisitions which were completed in the same trailing twelve-month period.
