What is the purpose of A.M. Best’s financial strength ratings
To provide an opinion on the financial strength of an insurer (and it’s ability to meet ongoing obligations to policyholders)
What is the BCAR formula?
BCAR = (AC-NRC)/AC x 100
How is AC (Available Capital) calculated in the BCAR formula
Identify adjustments to balance sheet capital to obtain BCAR Available Capital
Equity Adjustments:
+ Loss reserves
+ Unearned premiums
+ Reinsurance
+ Assets
Debt adjustments:
+ Surplus notes
+ Debt service requirements
Other adjustments:
- Future operating costs
- Intangibles
- Goodwill
Why don’t we use unadjusted reported capital as the value for AC (Available Capital)
Incorporating these adjustments provides for a more economic and consistent view of capital available
Identify the risk categories in the BCAR model
What is the purpose of the covariance adjustment in the NRC formula?
Why is B7, Business risk, excluded from the covariance adjustment?
A.M. Best expects an insurer to maintain capital for business risks without the benefit of diversification
In the BCAR model, what is “gross required capital”
Gross required capital = direct SUM of required capital for B1 to B8
(represents total required capital if all risks developed simultaneously)
What is the formula for NRC
What is the key idea in calculating the required capital for each risk category?
Multiply the liability from each risk category by a specific capital factor (similar to MCT)
Briefly describe how BCAR “capital factors” for reserve risk are derived
Derivation of reserve capital factors is:
- Based on industry factors
- Then adjusted for company’s volatility in case loss development
Identify considerations other than BCAR score that impacts Best’s balance sheet strength assessment
Q2-SALAMI
Q2: Quality of Capital, Quality of Reinsurance
Stress testing (how well does the company perform under stress)
Adequacy of reserves
Liquidity of capital
Actions of affiliates (affiliates could drag you down or pull you up)
Matching of assets & liabilities (this is desirable for paying your bills on time)
Internal capital models (does the company have a good procedure for assessing its own capital needs)
Identify the 6 steps in A.M. Best’s rating process (leading to the final issuer credit rating)
[BOB ECL]
BOB-ECL
Balance sheet strength (mainly based on the BCAR scores, but subject also to Q2-SALAMI)
Operating performance
Business profile
ERM
Comprehensive adjustment
Lift and/or drag of rating
Identify company characteristics that may tend to lower a company’s BCAR score (5)
Why does A.M. Best calculate NRC and BCAR at more than 1 level of VaR?
Why does A.M. Best use a sensitivity analysis to supplement its BCAR calculation?
Can also reflect other changes, such as those expected to affect business mix and the investment portfolio.
Identify an aspect of the BCAR model that may make it more robust than MCT
BCAR model permits qualitative adjustments to final assessment for economic conditions such as:
- Interest rate changes
- Stage of U/W cycle
- Changes in reinsurance arrangements
(these are essentially market adjustments within the BCAR framework)
Describe 3 similarities between the BCAR model and MCT
Purpose: assess financial strength & ability to meet policyholder obligations
Key idea: apply capital factors to liabilities in various risk categories
Covariance adjustment (to account for the statistical independence between risk categories)
Describe 3 differences between the BCAR model and MCT
Formula:
- BCAR max = 100%, no minimum
- MCT min = 0%, no maximum
Robustness
- A.M. Best is more robust because final assessment includes qualitative economic conditions
Time horizon
- BCAR capital must support current & future premium risk
- MCT focuses more on current year’s risk
