The European Commission has approved under EC Treaty State aid rules the €5 billion risk shield and accompanying measures for German bank WestLB, following an in-depth investigation opened in October 2008. The risk shield was authorised by the Commission as temporary rescue aid on 30 April 2008. In light of the far-reaching measures to be implemented to restore WestLB's long-term viability without undue distortions of competition, the Commission concluded that the aid was compatible with the Single Market. In particular, WestLB will refocus on less risky activities and reduce its size by half. WestLB AG, based in North Rhine-Westphalia, had total assets of €286.6 billion as at 31 December 2007. In its capacity as a German Landesbank, WestLB acts as a central bank and link to global financial markets for savings banks in NRW and Brandenburg, as well as being a commercial bank operating on an international scale. The Commission's decision is conditional upon the approval of the restructuring plan by the statutory bodies of all of WestLB's owners.
