Structure & Strategy

Diversified flow of income

Our business model combines several sources of income. It is based on sustainable income from the management of our Commercial Portfolio and recurring management in­come from a broad range of services for third parties (In­stitutional Business), supplemented by equity returns from our structured investments.

Generating income streams from two complementary seg­ments ensures continuous profitability and enables us to exploit opportunities with maximum independence from market cycles.There are strong synergies between both segments on our platform:

Combining the financial and balance sheet structure of a portfolio holder with the management expertise of an active asset manager enables us to exploit market opportunities quickly and flexibly while at the same time ensuring exceptional reliability and providing full-service solutions across all phases of the value chain.
