Not for distribution in or into Australia, Canada, the Hong Kong special
administrative region of the People's Republic of China, Japan, New Zealand,
South Africa or the United States.

The Competition Directorate-General of the EU Commission has completed the first
phase of its investigation under the EU Merger Regulation into the transaction
between Ahlstrom's Label and Processing business and Munksjö AB and opened an
in-depth (second phase) investigation into the proposed combination with respect
to abrasive backings and pre-impregnated decor paper. The Commission now has 90
working days, until April 29, 2013, to take a final decision on whether the
combination would significantly impede effective competition in the European
Economic Area (EEA) or any substantial part of it.

Ahlstrom and Munksjö AB continue to work closely with the Commission in order to
allow the Commission to complete its review as quickly as possible, aiming at a
completion of the demerger of Ahlstrom's Label and Processing business in Europe
and other related measures forming the first phase of the planned transaction
during the first quarter of 2013. It is, however, possible that the completion
of the first phase of the planned transaction will not take place until the
second quarter of 2013.

On November 27, 2012, Ahlstrom's Extraordinary General Meeting approved the
demerger concerning Ahlstrom's Label and Processing business in Europe and the
demerger concerning Ahlstrom's Label and Processing business in Brazil in
accordance with the demerger plans.
