Kai Ostermann
Chairman of the Board
"Although the strategic positioning of Deutsche Leasing as the asset-finance partner of small and medium-sized businesses in Germany is a particular interest of mine, it has to be carried out in perfect coordination with all business units. So my colleagues on the Board and I act in close accord, because ultimately we want to increase the satisfaction of our clients and expand our client base. Above all else, this requires the dedication of all our staff.
I see the key growth areas for Deutsche Leasing in our alliance with the savings banks, in the increasing internationalisation of Deutsche Leasing and in expanding our portfolio of standardised solutions. Our conservative risk policy forms the foundation for our business and will be maintained rigorously as we develop future market opportunities."

"We pursue a conservative yet opportunity-oriented risk strategy and realise investments which we – due to our asset expertise and our national as well as international industry knowledge – are able to soundly evaluate. Looking beyond just credit risks enables us to take a broader range of actions in doing business with clients, thereby tapping additional business potential. We strive to create the appropriate ratio of costs, risk and earnings for all business relationships and actively manage the risk portfolio by dividing and diversifying the risks.
This risk strategy supports Deutsche Leasing’s vision of being the leading asset finance partner in terms of customer orientation, market positioning and profitability."

Member of the board
„German medium-sized companies are locally rooted but globally active - in some cases as global market leaders with specialized products. We support them in achieving their goals in Germany and worldwide. For over 30 years, we have been assisting German medium-sized companies with their investments abroad - in developing new sales markets, expanding production sites and other direct investments. In over 20 countries, we provide them with our know-how and services directly on site in the respective national languages as well as in German or English. Since we are a member of the saving banks global network – S CountryDesk –, customers of the saving banks can take advantage of the services and expertise of Deutsche Leasing.”
