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). Based on this assessment, management has concluded that ABB’s internal control over financial reporting was effective as of December 31, 2017.
Ernst & Young AG, the independent registered public accounting firm who audited the Company’s consolidated financial statements, has issued an opinion on the effectiveness of ABB’s internal control over financial reporting as of December 31, 2017, which is included on page 143 of this Annual Report.
