The insurance capital adequacy ratio is a crucial metric that helps insurance companies manage their financial risks and stay afloat in a competitive market. It measures the amount of capital an insurer has in relation to its risk-weighted assets.
In simple terms, the insurance capital adequacy ratio is a percentage that represents the minimum amount of capital an insurer must hold to cover potential losses. This ratio is set by regulatory bodies to ensure that insurers can meet their financial obligations.
A lower capital adequacy ratio can be a red flag for investors and regulators, indicating that an insurer may be taking on too much risk. On the other hand, a higher ratio can provide peace of mind for stakeholders, knowing that the insurer has a solid financial foundation.
Understanding the Calculation
The CR Requirement is a crucial calculation in determining a firm's capital adequacy. It's equal to the higher of the base capital resources requirement for the firm's business and the specific capital requirement for that business.
For firms carrying on general insurance business, the CR Requirement is the higher of the base capital resources requirement for general insurance business and the general insurance capital requirement. This is the same for firms carrying on long-term insurance business, but with the base capital resources requirement and long-term insurance capital requirement.
If a firm is a pure reinsurer, the CR Requirement is simply the general insurance capital requirement for its general insurance business and the long-term insurance capital requirement for its long-term insurance business. But if the general and long-term insurance capital requirements are lower than the base capital resources requirement, the firm has a single CR Requirement for its entire business.
Calculation of CR
The CR Requirement is a crucial concept in the insurance industry, and understanding how it's calculated is essential. The CR Requirement is the higher of two values: the base capital resources requirement for the type of business the firm is carrying out, and the specific capital requirement for that type of business.

There are two types of business: general insurance and long-term insurance. The calculation for each is slightly different. For general insurance business, the CR Requirement is the higher of the base capital resources requirement and the general insurance capital requirement.
The base capital resources requirement is a fundamental aspect of the CR Requirement. It's the minimum amount of capital a firm must have to operate. The specific capital requirement, on the other hand, is tailored to the type of business the firm is carrying out.
Here's a breakdown of the two types of business and their respective CR Requirements:
In summary, the CR Requirement is calculated differently for general insurance and long-term insurance business. Understanding the specific requirements for each is essential for firms operating in the insurance industry.
Calculation of Pure Reinsurers' Capital Requirements
For pure reinsurers, the calculation of capital requirements is a bit more straightforward. The CR Requirement in respect of general insurance business is the general insurance capital requirement.
If a pure reinsurer's business is solely made up of general insurance, that's all you need to worry about. However, if it's a mix of general and long-term insurance, you'll need to consider both requirements.
In fact, the general insurance capital requirement is the CR Requirement for general insurance business, and the long-term insurance capital requirement is the CR Requirement for long-term insurance business. If either of these requirements is lower than the base capital resources requirement, the firm's CR Requirement is actually the base capital resources requirement.
Here's a quick summary of the CR Requirements for pure reinsurers:
Note that if the base capital resources requirement is lower than either of these, the CR Requirement is actually the base capital resources requirement.
Understanding Relativity
BCAR emphasizes the balance sheet because it shows whether an insurer will be able to meet its policy obligations.
The balance sheet strength is critical to the determination of a rating unit's ability to meet its current and ongoing obligations.

BCAR takes into account the premiums currently written by the insurer, reinsurance coverage, and loss reserves.
Underwriting practices, specifically underwriting leverage, determine whether the insurer is underwriting the policies that it should be underwriting, or if it is taking on too much risk.
The basic formula for BCAR is APHS divided by NRC, where APHS takes into account various adjustments and NRC components include fixed-income securities, equities, and interest rates.
A rating is more than a balance sheet strength assessment and includes evaluations of a rating unit's operating performance, business profile, and enterprise risk management.
BCAR alone does not decide the balance sheet strength assessment, as other factors such as liquidity, quality of capital, and reinsurance also impact the analysis.
Banks are also held to capital adequacy ratios to ensure they have enough reserves on hand to meet adverse financial situations as well as customer demand for deposits.
Components of the Ratio
The insurance capital adequacy ratio is a complex concept, but let's break it down to its core components.
The ratio assesses an insurer's available capital against various risk categories.
In the US, this is done through eight risk categories, which help determine if an insurer's capital is adequate.
The ratio also considers five Value at Risk (VaR) scenarios, which provide a more comprehensive picture of an insurer's capital needs.
These VaR scenarios allow you to see which risks create more required capital at each level, giving you a clearer understanding of your organization's capital needs.
Brought Forward Amount
The brought forward amount is a crucial component of the ratio, and it's calculated using the general insurance capital requirement for the prior financial year. This amount is then adjusted based on the ratio of technical provisions for claims outstanding at the end of the prior financial year to the technical provisions for claims outstanding at the beginning of the prior financial year.
If the technical provisions are zero, the calculation changes to use technical provisions calculated gross of reinsurance. This is a key distinction to keep in mind when working with the brought forward amount.

To give you a better idea of the calculation, let's break it down into the two possible scenarios. If the amount of technical provisions calculated net of reinsurance is not zero, the brought forward amount is calculated as follows:
- Technical provisions (calculated net of reinsurance) for claims outstanding at the end of the prior financial year
- Divided by
- Technical provisions (calculated net of reinsurance) for claims outstanding at the beginning of the prior financial year
If the amount of technical provisions calculated net of reinsurance is zero, the calculation changes to use technical provisions calculated gross of reinsurance. In this case, the brought forward amount is calculated as follows:
- Technical provisions (calculated gross of reinsurance) for claims outstanding at the end of the prior financial year
- Divided by
- Technical provisions (calculated gross of reinsurance) for claims outstanding at the beginning of the prior financial year
The result of this calculation is the brought forward amount, which is then used to determine the ratio.
The Claims Amount
The claims amount is a crucial component of the ratio, and it's calculated in a specific way. To start, you have 26% of the gross adjusted claims amount, which is then multiplied by the reinsurance ratio.
The gross adjusted claims amount is determined by taking the amount of gross claims incurred over the reference period, which is then adjusted in a few key ways. First, for a pure reinsurer that ceased conducting new reinsurance contracts before December 31, 2006, the amount is increased by 50% for claims incurred in 11, 12, and 13.
There are a few different ways to calculate the gross adjusted claims amount, depending on the specific circumstances. For general insurance business class 18, the amount of claims incurred is based on the costs recorded in the firm's books in the reference period.
The reference period to be used for calculating the gross adjusted claims amount can vary. It's either the financial year in question and the two previous financial years, or the period the firm had been in existence at the end of the financial year in question, if shorter.
Here's a summary of the steps to calculate the gross adjusted claims amount:
- Take the amount of gross claims incurred over the reference period
- Except for a pure reinsurer that ceased conducting new reinsurance contracts before December 31, 2006, increase the amount by 50% for claims incurred in 11, 12, and 13
- Deduct 66.7% of the claims for actuarial health insurance that meets the conditions set out in 13.1
- Multiply the resulting figure by 12 and divide by the number of months in the reference period
Reinsurance Ratio
The reinsurance ratio is a crucial component of the overall ratio, and it's determined in accordance with the insurance accounts rules. It's adjusted for transfers that were approved by the authority with responsibility for the approval of transfers of portfolios of contracts of insurance at the relevant time.
To calculate the reinsurance ratio, you need to consider two main factors: the ratio calculated in (a) and (b). If this ratio lies between 50% and 100%, the reinsurance ratio is the ratio expressed as a percentage.
Here's a breakdown of the reinsurance ratio:
Health Risk Protection
Health Risk Protection is a crucial component of the ratio, and it's defined in a specific way. The insurance health risk and life protection reinsurance capital component is the highest of three categories.
Contracts of insurance that fall under long-term insurance business class IV are included, as long as they meet certain conditions. This is specified in section 13.1, with modifications outlined in 16.3.
Risks that fall under general insurance business classes 1 or 2, but are written as part of a contract of long-term insurance, are also included. This is a key consideration for insurers.
In the case of a pure reinsurer or a mixed insurer, life protection reinsurance business is also included in the calculation. This highlights the importance of reinsurance in managing health risk protection.
The three categories are:
Expense Risk Component

The Expense Risk Component is a crucial part of the Ratio. It's used to calculate the risk associated with insurance expenses.
In the case of long-term insurance business classes III, VII, and VIII, the Expense Risk Component is 25% of net administrative expenses. This applies only if the firm bears no investment risk and the allocation to cover management expenses in the contract of insurance doesn't have a fixed upper limit that's effective for more than five years.
For tontines, which are a type of long-term insurance business class V, the Expense Risk Component is 1% of the assets of the tontine.
Other long-term insurance businesses have an Expense Risk Component of 1% of the adjusted mathematical reserves.
Here's a breakdown of the Expense Risk Component for different types of long-term insurance businesses:
Market Risk Component
The market risk component is a crucial part of the overall ratio calculation. It's calculated as 3% of the adjusted mathematical reserves for most insurance liabilities.

However, there are some exceptions. For instance, if the firm doesn't bear any investment risk, the market risk component is not applicable. This is the case for long-term insurance business classes III, VII, or VIII.
Additionally, if the firm is a pure reinsurer or mixed insurer, the market risk component only applies to certain types of contracts. These include contracts falling within specific business classes.
To calculate the market risk component, you'll need to know the adjusted mathematical reserves for each category of insurance liability. This involves multiplying the mathematical reserves by a specific ratio, which can be 85% or 50% for pure reinsurers.
The ratio is determined by the firm's financial year, and it's used to calculate the adjusted mathematical reserves for each category of insurance liability.
Risk Components
The insurance capital adequacy ratio is a crucial measure of a company's financial health. The ratio is calculated by dividing the company's available capital by its risk-weighted assets.
Risk components play a significant role in determining the capital adequacy ratio.
The Basel Committee on Banking Supervision (BCBS) sets the risk weights for different types of assets, such as loans and securities.
A higher risk weight means that the asset is considered riskier and requires more capital to be set aside. For example, residential mortgage loans are typically given a lower risk weight of 50%, while commercial mortgage loans are given a higher risk weight of 100%.
Limitations of Relativity
BCAR is not a one-size-fits-all solution for assessing insurance company financial strength. The analysis of BCAR alone does not decide the balance sheet strength assessment.
Other factors can impact the balance sheet strength analysis, including liquidity, quality of capital, dependence on reinsurance, and reserve adequacy. BCAR takes into account premiums, reinsurance coverage, and loss reserves, but other factors like asset/liability matching and stress tests are also important.
A rating is more than a balance sheet strength assessment, it also includes evaluations of operating performance, business profile, and enterprise risk management. BCAR emphasizes the balance sheet because it shows whether an insurer will be able to meet its policy obligations.
The 2007-2008 financial crisis hit insurance companies hard, and many incorrectly priced risk, leading to insurers taking on more risk than they could cover with their reserves. BCAR can assist analysts in differentiating among the financial strength of insurers, but it's not foolproof.
Insurance regulators need to consider a range of factors when assessing an insurer's financial strength, including liquidity, quality of capital, and reinsurance arrangements. BCAR provides a guideline for the net required capital needed to support balance sheet strength, but it's just one tool in the regulator's toolbox.

Resources
A firm must maintain at all times capital resources equal to or in excess of its CR Requirement. This is crucial for its financial stability.

Capital resources are the firm's financial backbone, and it's essential to ensure they meet the minimum requirement. A firm that fails to meet this requirement may face severe consequences.
A firm that carries on both long-term insurance business and general insurance business must comply with specific regulations. This means applying different rules for each type of business, unless it's a pure reinsurer.
Here's a breakdown of how firms must comply with these regulations:
- Firms must comply with 3.1 for both long-term and general insurance business.
- They must apply 4.2 and 4.3 separately for each type of business.
- Pure reinsurers have a single CR Requirement for their entire business.
Long-Term and General
The insurance capital adequacy ratio is a long-term and general concept that's essential to understand. The ratio is a measure of an insurer's ability to meet its long-term obligations, such as paying claims.
Typically, a higher capital adequacy ratio indicates a stronger financial position, which can provide peace of mind for policyholders. A ratio of 200% or more is often considered healthy.
Regulators often set minimum capital requirements to ensure insurers can withstand unexpected losses. This helps maintain market stability and protect policyholders.
What Is Relativity?

Relativity is a concept that helps us understand how different scenarios can impact an insurance company's balance sheet. It's a rating system that examines an insurer's leverage, underwriting activities, and financial performance.
BCAR, or Best's Capital Adequacy Relativity, is a specific type of relativity that tests how different scenarios would affect an insurer's balance sheet. This includes examining the insurer's leverage and underwriting activities.
Relativity helps us understand how different factors can impact an insurer's financial stability. It's not just about the numbers, but also about how they interact with each other.
BCAR uses a combination of financial data and statistical models to determine an insurer's relativity score. This score can be used to compare the financial stability of different insurers.
Long-Term
Long-term insurance businesses have specific requirements to meet, and one of the key components is the capital requirement. This is calculated as the sum of five different risk components.
The insurance death risk capital component is one of these key parts. This component is crucial in ensuring that a firm can cover the risk of policyholders dying.

A firm carrying on long-term insurance business must also calculate the insurance health risk and life protection reinsurance capital component. This component is vital in covering the risk of policyholders falling ill or requiring medical treatment.
The insurance expense risk capital component is another essential part of the calculation. This component helps to ensure that a firm can cover its expenses, such as administrative costs.
In addition to these components, a firm must also consider the insurance market risk capital component. This component helps to ensure that a firm can cover the risk of market fluctuations affecting its investments.
Lastly, the resilience capital requirement is also a critical component. This requirement helps to ensure that a firm can withstand unexpected events or changes in the market.
Here is a summary of the five components that make up the long-term insurance capital requirement:
- Insurance death risk capital component
- Insurance health risk and life protection reinsurance capital component
- Insurance expense risk capital component
- Insurance market risk capital component
- Resilience capital requirement
General
General insurance businesses have specific capital requirements.
A firm carrying on general insurance business must calculate its general insurance capital requirement as the highest of three amounts: the premiums amount, the claims amount, and the brought forward amount.

The premiums amount is a key factor in determining the capital requirement. This amount is likely to be significant for firms that write a large volume of policies.
The claims amount is another important factor in determining the capital requirement. This amount can be unpredictable and may vary significantly from year to year.
The brought forward amount is also a key factor in determining the capital requirement. This amount represents any outstanding claims or liabilities from previous years.
In some cases, a firm may need to use a different reference period to calculate its capital requirement. For example, a firm that underwrites only certain types of general insurance business risks may need to use a different reference period.
Here are the types of general insurance business risks that may require a different reference period:
- Credit risk (as included in general insurance business class 14)
- Storm risk (as included in general insurance business class 8)
- Hail or frost risk (as included in general insurance business class 9)
Actions and Next Steps
The insurance capital adequacy ratio has been increased to 2.5%, which is a significant jump from the previous 1.5%. This change is aimed at enhancing the financial stability of insurance companies.
To maintain this higher ratio, insurance companies will need to hold more capital in reserve. This means they'll have to adjust their investment strategies and risk management techniques.
Insurance companies that fail to meet the new capital adequacy ratio may face penalties, fines, or even be forced to merge with other companies. In extreme cases, they might even be declared insolvent.
Regulators will closely monitor the financial health of insurance companies to ensure they're meeting the new capital adequacy ratio. This will involve regular audits and assessments.
The increased capital adequacy ratio will likely lead to higher premiums for consumers, as insurance companies pass on the costs of holding more capital. However, this may also provide consumers with greater peace of mind knowing their insurance company is better equipped to handle claims.
Frequently Asked Questions
