Ernst & Young are the auditors of ABB’s statutory and consolidated accounts.

Duration of the mandate and term of office of the auditor

Ernst & Young assumed the auditing mandate of the ABB Group in 1994. The head auditor responsible for the mandate, Nigel Jones, began serving in this function in respect of the financial year ended December 31, 2008.

Pursuant to the Articles of Incorporation, the term of office of ABB’s auditors is one year.

Auditing and additional fees paid to the auditor

The audit fees charged by Ernst & Young for the legally prescribed audit amounted to approximately $28.6 million in 2012. Audit services are defined as the standard audit work performed each fiscal year necessary to allow the auditors to issue an opinion on the consolidated financial statements of ABB and to issue an opinion on the local statutory financial statements.

This classification may also include services that can be provided only by the auditors, such as assistance with the application of new accounting policies, pre-issuance reviews of quarterly financial results and comfort letters delivered to underwriters in connection with debt and equity offerings.

In addition, Ernst & Young charged approximately $8.0 million for non-audit services performed during 2012. Non-audit services include primarily accounting consultations and audits in connection with divestments, audits of pension and benefit plans, accounting advisory services, tax compliance and other tax services. In accordance with the requirements of the U.S. Sarbanes-Oxley Act of 2002 and rules issued by the SEC, ABB has, on a global basis, a process for the review and pre-approval of audit and non-audit services to be performed by Ernst & Young.
