German investment and asset manager Corpus Sireo has signed new mandates worth a total of EUR 1 bn in assets under management so far this year.

The Cologne-based group said the new mandates lift its assets to EUR 15.4 bn managed for a number of clients, including institutional investors, banks and companies with owner-occupied real estate. With a portfolio covering 14.5 million m2, the company claims to be the largest real estate asset manager in the country.

Recent appointments include the management for the Neue Deutsche Bank Türme office scheme in Frankfurt am Main, as well as two marketing accounts for private-equity investor Cerberus, and the AXA Investment Managers fund investment company.

'Our goal for 2011 was to acquire new mandates worth EUR 1 bn and we are already very close to achieving this goal,' said Said Ingo Hartlief, CEO of Corpus Sireo Asset Management. 'And we remain optimistic that we will acquire additional mandates soon.'

The company said it is seeking to expand particularly in the international client segment, with a view of becoming 'the Germany specialist for international real estate investors'. It has managed or still manages accounts for Morgan Stanley, Citigroup, Brookfield Europe, and the Royal Bank of Scotland.
