Disclosure Under Chapter 2 Section 9 of the Securities Market Act

Sampo plc (business code 0142213-3) has today received a disclosure under
Chapter 2, Section 9 of the Securities Markets Act, according to which the total
number of Sampo A shares and related voting rights owned by Capital Group
Companies, Inc. exceeded on 3 September 2012 one twentieth (1/20) of Sampo plc's
entire stock and voting rights.

Previously Capital Research and Management Company (CRMC) and Capital Group
International, Inc. (CGII), members of the Capital Group Companies, Inc.,
reported holdings separately based on an exemption granted by the Finnish
Financial Supervision Authority on 12 September 2007 (J No 13/2230/2007). As a
result of the corporate re-organization effective 1 September 2012, the
exemption no longer applies to CRMC and CGII. Consequently, The Capital Group
Companies, Inc. now reports its holdings in their entirety.
