Report of management on internal control over financial reporting

The Board of Directors and Management of ABB Ltd and its consolidated subsidiaries (“ABB”) are responsible for establishing and maintaining adequate internal control over financial reporting. ABB’s internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation and fair presentation of the published Consolidated Financial Statements in accordance with U.S. generally accepted accounting principles.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with ABB’s policies and procedures may deteriorate.

Management conducted an assessment of the effectiveness of internal control over financial reporting based on the criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Management’s assessment of the effectiveness of internal controls over financial reporting excludes the evaluation of the internal controls over financial reporting for GE Industrial Solutions (GEIS), which was acquired on June 30, 2018. The total assets of GEIS represent 8 percent of total assets of the Company as of December 31, 2018, and the revenues and loss from continuing operations, before taxes, represent 5 percent and 1 percent of total revenues and income from continuing operations before taxes, respectively, of the Company for the year then ended.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s financial statements will not be prevented or detected on a timely basis. We have identified a material weakness in our information technology general controls (ITGCs) based on deficiencies in selection, development, and monitoring of control activities in ITGCs. We did not maintain sufficient user access or segregation of duties controls in certain applications in North America as well as for select Group applications. As a result of these deficiencies, the process level controls dependent on the affected applications, could not be relied upon.

This material weakness did not result in any misstatements in the financial statements. However, due to the existence of the material weakness, a reasonable possibility exists that material misstatements in the Company’s financial statements would not have been prevented or detected on a timely basis.

We completed additional substantive procedures prior to filing this annual report to ensure that the financial statements, prepared in accordance with U.S. GAAP, were not materially misstated. Based on these procedures no adjustments to our financial statements were required.

Based on its evaluation, our management has concluded that, as of December 31, 2018, as a result of the material weakness described above, our internal control over financial reporting was not effective.

KPMG AG, the independent registered public accounting firm who audited the Company’s consolidated financial statements, has issued an adverse opinion on the effectiveness of ABB’s internal control over financial reporting as of December 31, 2018, which is included on pages 140–141 of this Annual Report.
