On November 14, 2016 A.M. Best released an update on the BCAR calculation. Following a commentary period that ended in June 2016, Best analyzed the industry feedback. The response and discussions led to a number of key changes to the original calculation in the draft BCRM and P/C BCAR calculation, summarized below:
- Value at Risk (VaR) confidence intervals of 99.8 and 99.9 (500- and 1000-year return periods) have been replaced with 99.6 (250-year return period) in the BCAR calculation. The 99.8 (500-year return period) confidence interval will still be calculated but will only be used for the ERM assessment building block and not for BCAR.
- Net catastrophe exposure will no longer lead to a full 100% capital charge. The charge for net catastrophe exposure will now be included within the covariance adjustment, to recognize the inherent diversification from non-cat risks.
- Assessment of Balance Sheet Strength, the first building block within the BCRM, will incorporate an excess capital buffer. To attain the highest classifications of “Strongest” and “Very Strong,” rated entities will need to maintain capital levels above the buffer at the 99.6 VaR, with preliminary thresholds shown here:
- The charge for reinsurer concentration has been removed from the BCAR calculation. The Balance Sheet Strength (BSS) assessment will still consider reinsurer concentration, as well as reinsurance dependence, quality of reinsurance, and other qualitative factors.
Overall, practicality and transparency have been improved by providing the resultant “stochastic-based factors” emanating from the simulation modeling underlying the BCAR model. In making these factors available, A.M. Best will enable analysts to perform pro forma scenarios to measure the impact of strategic business decisions concerning growth, profitability, asset mix, reinsurance, and all other capital charges. Holborn works closely with clients to model, measure, and test the effect of adjusting these risk factors on BCAR.
Holborn’s Supporting Analytics
During the comment period and in consultation with several clients, Holborn expressed concerns to Best’s over the VaR calculation and full capital charge for cat risk. Scott Rosenthal, SVP & Head of Actuarial commented: “We are very pleased to see A.M. Best’s response to the concerns of the industry. These meaningful changes to the draft methodology will improve the model’s reliability by reducing the volatility in the tail and reflecting the natural diversification benefit of non-correlated insurance risks.”
In addition to modeling any possible changes to BCAR, Holborn is helping clients to quantify BCAR tolerance and evaluate their own view of risk in the context of growth strategies. Holborn’s proprietary OptimEyes provides a comprehensive and realistic approach to catastrophe portfolio optimization (for both growth or depopulation situations).
OptimEyes marries strategic and risk tolerance objectives, while providing an allowance to include some risks that don’t meet specific criteria (at the selection of the client) to better resemble the commercial decisions primary carriers make every day. The analysis is fully integrated into Holborn’s exposure management tool,Eye-In-The-SkySM.
A.M. Best estimates another comment period until March 2017, with formal roll-out of the new BCAR calculation schedule for mid-year 2017.
