Under its Articles of Association, the company shall have a minimum of one and a maximum of two auditors who are auditors or firms of independent public accountants authorised by the Central Chamber of Commerce of Finland. The Annual General Meeting elects the auditors to a term of office ending at the close of the next Annual General Meeting. Proposals to the Annual General Meeting on the election of auditors which have been made known to the Board prior to the Annual General Meeting will be made public if the proposal is supported by shareholders holding a minimum of 10% of all the company's shares and voting rights and if the person or company proposed has consented to such nomination. The company's auditors submit the statutory auditor's report to the company's shareholders in connection with the company's financial statements. The auditors also report their findings to the Board of Directors on a regular basis. The parent company, Outokumpu Oyj, is audited by KPMG Oy Ab, and the responsible auditor is Mauri Palvi, Authorised Public Accountant. KPMG Oy Ab is also responsible for overseeing and coordinating the auditing of all Group companies.

Both Outokumpu and KPMG Oy Ab highlight the requirement for an auditor to be independent of the company being audited. In its global independence policy, KPMG Oy Ab has stated its commitment to applying the Code of Ethics of the International Federation of Accountants (IFAC).

Outokumpu's Board Audit Committee continuously monitors the global level of non-audit services purchased by the Group from KPMG Oy Ab. In 2009, auditors were paid fees totalling EUR 1 million, of which non-auditing services accounted for EUR 0 million.
