A Munich-based global reinsurer (EUR 52B gross premiums written, 40,000 employees across 50 countries, operating in all major reinsurance lines — property catastrophe, casualty, life and health, and specialty) faced productivity and knowledge management challenges across its underwriting and actuarial functions. (1) Treaty renewal volume: the reinsurer processed approximately 35,000 treaty renewals annually (concentrated in the January 1 and July 1 renewal seasons).
Each renewal required: portfolio analysis (reviewing the ceding company's loss experience, premium volume, and risk profile — typically from a data submission of 50-200 pages), exposure modelling (for catastrophe-exposed treaties — running the cedant's portfolio through catastrophe models to assess risk), pricing analysis (applying the reinsurer's proprietary pricing models — with parameters adjusted for the specific risk, and benchmarking against market pricing), treaty wording review (reviewing the proposed contract terms — coverage provisions, exclusions, conditions, dispute resolution — comparing against the reinsurer's standard wordings and identifying deviations), and submission preparation (preparing the internal underwriting submission — a structured document presenting the analysis, risk assessment, and pricing recommendation for the underwriting committee). Thorough analysis of a complex treaty took 3-5 days for underwriters and 2-3 days for actuaries.
During the January 1 renewal season (when approximately 60% of treaties renewed), the workload was impossible — underwriters and actuaries worked 70+ hour weeks and still could not analyse every renewal at the depth they wanted. Triage was necessary: complex, large-premium treaties received thorough analysis, while smaller or more straightforward renewals received abbreviated review. (2) Actuarial documentation burden: Solvency II regulatory requirements meant that actuarial models, assumptions, and results had to be extensively documented.
The Solvency II standard formula and internal model calculations required: model documentation (comprehensive documentation of every actuarial model — methodology, assumptions, limitations, validation), ORSA narratives (Own Risk and Solvency Assessment — a forward-looking assessment of the reinsurer's risk and capital position, requiring actuarial analysis and narrative explanation), SCR calculation documentation (Solvency Capital Requirement — documenting how the SCR was calculated, which models were used, and what assumptions were made), and reserving reports (quarterly actuarial opinions on loss reserves — with detailed analysis of reserve development by line of business). Actuaries estimated that 45% of their time was spent on documentation rather than analytical work. (3) Knowledge concentration: the reinsurer's most valuable underwriting expertise resided with approximately 200 senior underwriters (average tenure: 18 years).
These individuals carried critical knowledge: client relationship history (decades of relationship context with ceding companies — their claims behaviour, negotiation patterns, and risk management quality), market cycle experience (understanding how pricing, capacity, and terms evolved across multiple underwriting cycles — essential for appropriate cycle positioning), and specialist technical expertise (deep knowledge of specific risk categories — earthquake engineering, hurricane modelling, cyber risk quantification, aviation liability). With 30% of these senior underwriters eligible for retirement within 5 years, the reinsurer faced a significant knowledge loss risk. Junior underwriters required 8-12 years to develop comparable expertise — and in a competitive talent market, many departed before reaching senior level. (4) Cross-office inconsistency: the reinsurer operated from 12 major underwriting offices worldwide (Munich, London, New York, Singapore, Sydney, Toronto, and others).
While corporate underwriting guidelines existed, interpretation and application varied by office — a treaty presented to Munich might receive different terms and pricing than the same treaty presented to New York. This inconsistency created adverse selection risk (brokers learning which office offered the most favourable terms) and complicated portfolio management. (5) Emerging risk assessment: new and evolving risk categories — cyber, climate change, pandemic, supply chain disruption — required underwriting approaches that could not rely heavily on historical loss data. Senior underwriters applied judgment and external research to assess these risks, but this analysis was ad hoc and not systematically captured or shared.
