Representative matters

A global asset management firm through one of its Luxembourg investment vehicles, on the sale of its portfolio company SACO Property Group to the Aparthotels group.

The lenders (including a group of financial institutions) on a USD75bn loan facility to support the takeover bid by Anheuser-Busch InBev of SAB Miller. This is the largest commercial loan in the history of the global loan markets, far surpassing pre-crisis values. Our involvement in the transaction, coming soon after our role in the financing of Royal Dutch Shell’s purchase of BG Group earlier in the year, reinforces A&O’s position as the global leader in the ‘super-jumbo’ loans market. Allen & Overy also advised the lenders on the loans supporting ABInBev's acquisition of Anheuser-Busch in 2008 (USD54bn) and Modelo in 2012 (USD14bn).

A global financial services group on a EUR2bn revolving credit facility for Fiat. The facility involved a syndicate of 19 banks.

A private equity firm, on the EUR1bn acquisition of a leading European supplier of aluminium profile systems for windows, doors, sliding elements, roof systems and conservatories with activities in Belgium, France, the UK and Poland.
