Allianz was founded as a transport and accident insurance firm in 1890 by Carl von Thieme and Wilhelm von Finck, the founders of Munich Re. It took the company five years to expand the business into Europe and North America and subsequently list in Berlin. After World War I, individuals were confronted with the loss of wealth, life, and security and Allianz founded a life business in the 1920s. In the years after World War II, Allianz's foreign assets were seized, and it lost its foreign business. By relocating its head office from Berlin to Munich in 1948, Allianz began the long road of rebuilding its domestic business. It took 20 years for the company to reacquire its prior foreign interests, starting in Austria. It became the largest European insurer in the postwar boom era.

Zurich is a multiline insurer that writes business across both life and nonlife insurance and also owns Farmers Management Services. Zurich was founded in 1872 as a marine reinsurer to provide reinsurance to its parent company. The company subsequently expanded into transport and accident insurance and rode the wave of transport technology innovation that drove rising demand for insurance. One of Zurich’s early principles was that setting prices too low would result in unfair claims handling, which would be damaging to both customers and Zurich. Over the years, Zurich has sought to combine customer goodwill through claims and a sufficient premium. Zurich is one of the most successful European multilines.

AXA’s origins date back to Ancienne Mutuelle, which was one of the few insurers that remained after the creation of the French social security system. With the threat of nationalization, a merger took place between Drouot and AXA (still known as Mutuelles Unies in 1982) and later Présence. Ten years later, AXA acquired North American life insurer Equitable Holdings. This was a time of expansion as AXA also bought the French insurer UAP. As markets crashed at the turn of the millennium, AXA decided to refocus its business and exited its stake in US investment bank Donaldson, Lufkin & Jenrette. A few years later the firm expanded again with the acquisition of Swiss insurer Winterthur. About five years ago, AXA started to reshape its portfolio to technical risks.

Dating back to 1879, Tokio Marine is Japan’s oldest insurance company and was its top property and casualty insurer in terms of market share for many decades. After mergers of its smaller rivals in the past few years, the company is now roughly the same size in the domestic nonlife market as MS&AD and Sompo, but it remains the most valuable listed Japanese insurer in terms of market capitalization due to its larger overseas business portfolio. The majority of its overseas business is in the US, where it has purchased four specialty insurers since 2008: Philadelphia Consolidated, Delphi Financial, HCC, and PURE.

It is also an emerging player in pharmacy benefit management and other healthcare services.

The roots of Generali date back to the 1830s and the Bora wind and rough seas that hit the Trieste region. Over that decade, Generali sought to expand throughout Italy, but this growth was held back by the fragmented nature of Italy. The Italian Revolution in the 1840s paved the way for easier expansion in the country. After World War I, Trieste was handed back to Italy. The dissolution of the Austro-Hungarian Empire created a fragmented Europe and a fragmented Generali. To this day, Generali remains quite a diversified company, but its core operations remain in the historical Austro-Hungarian countries of Austria, Central and Eastern Europe, Germany, and Italy. This is the case in Generali’s nonlife business, and France is also an important contributor to life and savings.

Munich Re was founded in 1880 by Carl Thieme amid a flurry of other reinsurance companies set up independently of primaries. In those early days, most reinsurers typically focused on a few strong customers. Thieme focused on a broader set of cedents to drive stronger growth in premiums. This coincided with a strategy of risk diversification and a preference to partner rather than take on a one-sided transfer of risk. In the 1890s, Munich Re introduced the first machinery insurance. After Thieme and Wilhelm von Fink founded Allianz, this was the main channel to sell insurance on machinery. We believe the approach of partnering with insurers and preferring to avoid one-sided risk, in conjunction with combining inspection and insurance services, remains at the heart of the firm.
