Frequently asked questions

Who runs investment decisions at ISSELHORSTER Insurance?

The management board, chaired by Stephan Schulze Westhoff with board member Michael Strüwer, oversees all operations including the general account. The supervisory board, led by Harald Koch, provides governance oversight. No dedicated CIO or external asset manager mandate is disclosed, suggesting an in-house treasury function sized for a regional insurer.

What investment assets does ISSELHORSTER Insurance hold?

Known positions include a listed corporate bond issued by Branicks Group AG, a German commercial real estate firm, and a directly owned commercial property at the firm's headquarters in Gütersloh. The balance-sheet asset mix likely also includes a core portfolio of German government and covered bonds, standard for a small BaFin-regulated insurer matching euro-denominated liabilities.

How does ISSELHORSTER's insurance cooperation model work?

The firm maintains active business partnerships with Gothaer, Allianz, Concordia, and Alte Oldenburger. These partnerships function as coinsurance and risk-pooling arrangements, allowing Isselhorster to underwrite larger policies or access reinsurance-like capacity without transferring the full client relationship. This model is common among small German mutual and regional stock insurers.

Is ISSELHORSTER Insurance a public company or a mutual?

The firm's legal structure is not explicitly disclosed, but its membership in the GDV (German Insurance Association) and BaFin oversight confirms it is a regulated insurer. The presence of a supervisory board and management board follows the German two-tier governance model required for stock corporations and larger mutuals. Its deep regional ties to Gütersloh, including local sports sponsorships, suggest a locally owned or mutual heritage.

Does ISSELHORSTER allocate to alternative assets beyond bonds and real estate?

No alternative allocations such as private equity, infrastructure, or hedge funds are disclosed. The known investment profile — corporate credit via Branicks Group and a directly held commercial property — indicates a conventional German insurer portfolio focused on fixed income and direct real estate. Solvency II capital charges for alternatives typically disincentivize small insurers from taking illiquid positions beyond real estate.
