In the life and annuity insurance sectors, AM Best’s ratings play a particularly important role due to the long-term nature of the commitments these companies undertake. A life insurer might be responsible for paying benefits decades into the future, while an annuity provider must ensure the steady flow of payments throughout a retiree's lifetime. Given these long-term obligations, consumers and financial planners rely heavily on AM Best's ratings to evaluate the financial health and reliability of insurers before making any decisions. Insurers that receive strong ratings from AM Best are more likely to inspire confidence among policyholders, thereby boosting their market presence and competitiveness. This article provides an in-depth examination of AM Best’s Credit Rating Methodology (BCRM), which is the framework used to assess and assign ratings. We will explore how AM Best calculates its Financial Strength Ratings (FSRs) and Best’s Capital Adequacy Ratio (BCAR) for life and annuity insurers. Additionally, we will provide practical examples of how BCAR is calculated, discuss the implications of these ratings for annuity buyers, and break down the key variables involved in the rating process.

Why AM Best Ratings Are Crucial for Life & Annuity Insurers

Life and annuity insurers operate in a market where trust is paramount. Policies often span decades, meaning the insurer must be financially solvent for long periods. AM Best’s ratings help bridge the trust gap by providing an independent, expert assessment of an insurer's ability to fulfill its promises over the long term. Consider a scenario where an individual purchases a deferred annuity at age 50, expecting income payments to begin at age 65. By the time the insurer starts making payments, 15 years will have passed, during which market conditions and the insurer’s financial position may have changed. The long-term nature of these products amplifies the importance of AM Best’s ratings. A company that holds an A++ rating at the time of purchase is more likely to remain financially secure when payments are due, compared to one with a lower rating. In extreme cases, a poor rating could indicate that an insurer might default, leaving policyholders and annuitants with reduced benefits or no payouts at all. AM Best's ratings serve as a hedge against potential future uncertainty, making them indispensable for long-term financial planning. Generally speaking, ratings are more relevant to customers who buy longer-term insurance contracts, as more time means more of a chance that an insurer could enter financial difficulty during that time.

Financial Strength Ratings (FSRs) for Life and Annuity Insurers

Definition and Significance

The Financial Strength Rating (FSR) is a critical indicator provided by AM Best that reflects an insurer’s ability to meet its policyholder obligations. These obligations may include paying life insurance benefits, providing annuity payouts, and covering long-term care or disability claims. AM Best’s FSRs range from A++ (Superior) to D (Poor), with several intermediate categories to differentiate the level of risk associated with each insurer. For life and annuity insurers, FSRs are of paramount importance because they offer a measure of the insurer's solvency and long-term viability. Unlike property and casualty insurance, where claims may be paid out within a short time, life and annuity products involve long-term commitments that could span several decades. As such, the financial strength of the insurer is vital to ensuring that these promises are kept over time. For example, consider a 30-year-old individual who purchases a life insurance policy today. The insurer is expected to maintain financial stability for potentially 50 or more years in order to pay the policy's death benefit. Similarly, annuities often involve lifetime payouts, meaning the insurer must be financially strong enough to make those payments for the remainder of the annuitant’s life, which could be 20, 30, or even 40 years into the future.

Why FSRs Matter to Consumers

Consumers, particularly those purchasing life insurance or annuities, pay close attention to FSRs because they represent a measure of trustworthiness. Insurers with high FSRs (A and above) are generally considered more reliable and less likely to default on their obligations. In contrast, insurers with lower FSRs may offer higher yields or lower premiums, but they come with an increased risk of default, especially during adverse economic conditions. For example, during the financial crisis of 2008, several insurers faced liquidity and solvency issues due to their exposure to risky investments. While most top-rated insurers weathered the storm, those with lower FSRs were more vulnerable, leading to increased scrutiny of their financial practices. Customers who had purchased annuities or life insurance from these lower-rated insurers faced uncertainty about whether their future payments would be honored. As a result, FSRs serve as a key criterion for consumers to evaluate the long-term safety of their retirement savings and life insurance policies.

Expanded Explanation of Financial Strength Ratings (FSRs)

AM Best’s FSR scale includes several ratings categories, each representing a different level of financial strength:

  • A++ and A+ (Superior): Insurers with these ratings have superior financial strength and are well-positioned to meet their ongoing policyholder obligations. They are often industry leaders with a strong market presence and significant capital reserves. For instance, a life insurer rated A++ might have a diversified portfolio of investments, a robust balance sheet, and a conservative underwriting approach. These factors reduce the likelihood of insolvency and ensure the insurer can meet claims and annuity payments over the long term.
  • A and A- (Excellent): Insurers rated A and A- are also considered excellent in terms of financial strength. While they may not have the same level of resources or market dominance as A++ insurers, they remain highly capable of meeting policyholder obligations. Many annuity buyers prefer working with insurers rated A or higher because they offer a balance of financial strength and competitive product offerings.
  • B++ and B+ (Good): These ratings indicate that the insurer is in a good financial position but may be more vulnerable to market fluctuations or adverse economic conditions. Insurers in this category are generally able to meet their obligations but may experience greater strain during times of financial stress. Annuity buyers should exercise caution with insurers in this category, particularly if the annuity contract involves long-term payouts.
  • B and B- (Fair): Insurers rated B and B- are considered fair in their ability to meet policyholder obligations. These companies may have weaker balance sheets or higher exposure to risky investments, making them more susceptible to economic downturns. Annuity buyers should be aware of the potential risks involved in working with insurers rated in this category, as their financial condition could deteriorate over time.
  • C++ and C+ (Marginal): Insurers with marginal ratings are financially unstable and may struggle to meet their obligations in the event of adverse conditions. These companies typically have low levels of capital and may be exposed to significant market risks. Consumers should avoid purchasing long-term financial products such as annuities from insurers in this category, as the risk of default is significantly higher.
  • C and C- (Weak): Insurers with weak ratings are highly vulnerable to financial instability and may be unable to meet their obligations. These companies are at risk of insolvency, particularly during periods of economic stress. Policyholders of such insurers face a significant risk of non-payment or delayed payments, making these insurers a poor choice for long-term contracts like annuities.
  • D (Poor): Insurers with a D rating are in poor financial condition and are highly likely to default on their obligations. These companies have little to no capital reserves and are often facing imminent insolvency. Policyholders should avoid insurers with this rating, as the likelihood of receiving payments is extremely low.

How AM Best Calculates Financial Strength Ratings (FSRs)

AM Best employs a rigorous and structured methodology to assign its Financial Strength Ratings (FSRs). This process involves a multi-step evaluation of several key factors that collectively determine an insurer's financial stability. These factors include:

  1. Balance Sheet Strength
  2. Operating Performance
  3. Business Profile
  4. Enterprise Risk Management (ERM)
  5. Comprehensive Adjustments & Rating Lift/Drag

Each factor is carefully assessed to ensure an accurate and comprehensive rating. If you’re looking to understand how AM Best assigns its ratings and the key factors they consider, watch this informative video below. It provides insight into the process behind AM Best’s insurance ratings and what they mean for insurers and policyholders. This video covers AM Best’s rating methodology, focusing on the evaluation of financial strength and how insurers are ranked based on their ability to meet policyholder obligations.

1. Balance Sheet Strength

The cornerstone of AM Best’s FSR calculation is the insurer’s balance sheet strength. A strong balance sheet indicates that the insurer has sufficient resources to meet its financial obligations, even in adverse circumstances. AM Best evaluates an insurer's balance sheet by examining capital adequacy, liquidity, asset quality, and reserve adequacy.

  • Capital Adequacy: AM Best uses the Best’s Capital Adequacy Ratio (BCAR) to measure an insurer’s capital adequacy. BCAR compares an insurer’s available capital to the amount of capital required to cover its risks. A higher BCAR indicates that the insurer has ample capital to absorb potential losses. Insurers with high BCARs are better positioned to weather financial storms, such as economic recessions or market downturns.
  • Liquidity: Liquidity refers to the insurer’s ability to quickly convert assets into cash to meet its short-term obligations. Insurers with high liquidity levels are better able to respond to unexpected events, such as an increase in claims or annuity payouts.
  • Asset Quality: AM Best assesses the quality of an insurer’s investment portfolio to determine the risk of potential losses. Insurers that invest heavily in high-risk assets, such as junk bonds or illiquid real estate, may be more vulnerable to financial instability.
  • Reserve Adequacy: Insurers must maintain sufficient reserves to cover future claims and policyholder obligations. AM Best evaluates the adequacy of these reserves to ensure that the insurer can meet its long-term commitments, particularly for life insurance and annuity products.

2. Operating Performance

Operating performance is crucial in assessing the insurer’s ability to generate sustainable earnings and manage risk. AM Best evaluates operating performance based on historical trends, profitability, volatility, and future projections. Consistent, strong operating performance is indicative of a well-managed insurer. AM Best looks at the overall profitability of the company’s operations, with a focus on long-term financial sustainability. Fluctuations in profit margins or operating income may signal risks that could affect the insurer's ability to meet its future obligations. AM Best also reviews key financial metrics such as return on equity (ROE), return on assets (ROA), and operating income growth to gain insights into the insurer's financial health. Insurers with positive and consistent operating results tend to receive higher ratings because they are better equipped to handle financial shocks and unexpected claims.

3. Business Profile

The business profile analysis evaluates the insurer's competitive position in the market. Factors such as geographic and product diversification, market leadership, and the strength of distribution channels are assessed. A diverse business profile is advantageous, as it reduces dependency on a single product line or geographic region. For example, an insurer with operations in multiple regions or a wide range of insurance products may be better positioned to weather economic downturns or changes in regulatory environments. Additionally, market leadership is a strong indicator of stability. Insurers with significant market share tend to benefit from economies of scale and increased customer loyalty, further bolstering their financial strength.

4. Enterprise Risk Management (ERM)

AM Best assesses an insurer's ERM framework by evaluating the management of exposure to capital volatility and the company's risk tolerance levels. An effective ERM strategy is a positive indicator of the company's ability to withstand financial shocks. ERM is not just about mitigating risks but also about strategically managing capital to maximize returns. Insurers with a robust ERM framework are often better able to anticipate potential risks, such as shifts in market conditions or changes in regulatory policies, and make adjustments accordingly. Key components of ERM include identifying risks, setting risk appetite levels, developing strategies for risk mitigation, and monitoring risk exposures over time. AM Best places a strong emphasis on ERM as it can significantly impact an insurer’s long-term success and ability to meet its obligations.

5. Comprehensive Adjustments & Rating Lift/Drag

Comprehensive adjustments consider any unusual factors not captured by the regular rating criteria. Rating lift or drag can be applied if the insurer’s parent company or affiliates have a positive or negative impact on the overall rating. For example, if an insurer is part of a larger group with significant financial resources, the insurer may benefit from a rating lift. Conversely, if the parent company or affiliates are facing financial difficulties, this may negatively impact the insurer's rating.

Technical Breakdown of BCAR Formula

The Best’s Capital Adequacy Ratio (BCAR), the key component of the first ratings step (Balance Sheet Strength) described above, plays a central role in AM Best’s rating process. It evaluates the amount of capital an insurer has relative to its risk exposure.

The formula for BCAR is:

BCAR = (Available Capital - Net Required Capital) / Available Capital * 100

Available Capital represents the total financial resources that the insurer can use to absorb potential losses. It includes equity capital, retained earnings, and reserves.

Net Required Capital accounts for all the risks an insurer faces, including investment risk, underwriting risk, market risk, and business risk. This calculation helps determine an insurer’s capacity to withstand financial stress.

BCAR (Best’s Capital Adequacy Ratio) Calculation Examples

Example 1: BCAR Calculation for an Annuity Insurer

Let’s consider an annuity insurer, Company A, with the following simplified balance sheet data:

    • Common Equity: $400 million
    • Preferred Equity: $100 million
    • Required Capital for Asset Risk: $200 million
    • Required Capital for Underwriting Risk: $100 million
    • Required Capital for Market Risk: $50 million
    • Required Capital for Business Risk: $50 million

Available Capital = $500 million

  • Calculation of Available Capital = $400M (Common Equity) + $100M (Preferred Equity) = $500 million

Net Required Capital: $400 million

  • Calculation of Net Required Capital: $200M (Asset Risk) + $100M (Underwriting Risk) + $50M (Market Risk) + $50M (Business Risk) = $400 million

BCAR Calculation:

  • Formula: BCAR = (500M - 400M) / 500M * 100 = (100M / 500M) * 100 = 20
  • Result: BCAR of 20
  • Assessment: Very Strong at the 99.6% VaR Confidence Level, per the table below:
VaR Confidence Level (%) BCAR BCAR Assessment
99.6 > 25 at 99.6 Strongest
99.6 > 10 at 99.6 & ≤ 25 at 99.6 Very Strong
99.5 > 0 at 99.5 & ≤ 10 at 99.6 Strong
99.0 > 0 at 99 & ≤ 0 at 99.5 Adequate
95.0 > 0 at 95 & ≤ 0 at 99 Weak
95.0 ≤ 0 at 95 Very Weak

 

Example 2: BCAR Calculation for a Smaller Life Insurer

Now, let’s consider a smaller life insurer, Company B, with the following simplified balance sheet data:

    • Common Equity: $200 million
    • Required Capital for Investment Risk: $80 million
    • Required Capital for Underwriting Risk: $60 million
    • Required Capital for Market Risk: $20 million
    • Required Capital for Business Risk: $20 million

Available Capital = $200 million

  • Calculation of Available Capital: $200M (Common Equity) = $200 million

Net Required Capital: $180 million

  • Calculation of Net Required Capital: $80M (Asset Risk) + $60M (Underwriting Risk) + $20M (Market Risk) + $20M (Business Risk) = $180 million

BCAR Calculation:

  • Formula: BCAR = (200M - 180M) / 200M * 100 = (20M / 200M) * 100 = 10
  • Result: BCAR of 10
  • Assessment: Strong at the 99.5% VaR Confidence Level

 

Net Required Capital Formula

The Net Required Capital is the amount of capital an insurer needs to support its financial risks, covering various risk categories such as investment, underwriting, market, and business risks. The formula used to calculate Net Required Capital is based on the assumption of statistical independence between several components...

  • C1: Investment risk (split into non-equity fixed income and equity securities),
  • C2: Underwriting risk (primarily mortality and morbidity),
  • C3: Market and interest rate risks, and
  • C4: Business risk.

Net Required Capital Formula

The Net Required Capital is the amount of capital an insurer needs to support its financial risks, covering various risk categories such as investment, underwriting, market, and business risks. The formula used to calculate Net Required Capital is based on the assumption of statistical independence between several components. The covariance adjustment helps reduce the overall required capital by accounting for diversification across different risk categories.

  • Net Required Capital = √[(C1-Non Eq + C3-Int)^2 + (C1-Eq + C3-Mkt)^2 + (C2)^2 + C4^2]

Where:

  • C1: Investment risk (split into non-equity fixed income and equity securities),
  • C2: Underwriting risk (primarily mortality and morbidity),
  • C3: Market and interest rate risks, and
  • C4: Business risk.

The formula shows how the required capital from different risk categories is combined, with adjustments for covariance between certain risks, such as investment and interest rate risks. This approach provides a more accurate measure of the total capital needed by the insurer while accounting for the benefits of diversification.

Risk Categories in BCAR

The risks factored into the BCAR calculation include:

  • Investment Risk: The risk of losses in the insurer’s investment portfolio due to market volatility or poor asset performance.
  • Underwriting Risk: The risk that policyholder claims may exceed expectations, affecting the insurer’s ability to pay out.
  • Market Risk: The risk of fluctuations in financial markets, which can affect asset values and liabilities.
  • Business Risk: The risk of general business risks tied to operations, such as life & annuity direct premiums, legal, regulatory, and competitive risks.

How AM Best Compares to Other Rating Agencies

While AM Best is the premier rating agency for life and annuity insurers, it is not the only one. Other well-known rating agencies include Moody’s, Fitch Ratings, and Standard & Poor’s (S&P). These agencies also assess insurers' creditworthiness but often use different methodologies, especially for non-insurance companies. AM Best focuses exclusively on the insurance industry, which gives it an edge in understanding the nuances of insurance company finances. By contrast, Moody’s, Fitch, and S&P cover a wider array of industries, offering credit ratings for banks, corporations, governments, and municipalities in addition to insurers. While all agencies are trusted, AM Best’s specialized knowledge makes it the gold standard for insurance ratings, particularly in evaluating life and annuity insurers. It places more emphasis on long-term obligations, which are vital for these sectors, while Moody’s, Fitch, and S&P often prioritize near-term liquidity and credit metrics. This makes AM Best ratings particularly important for consumers choosing life insurance and annuity products with long payout horizons.

Conclusion

AM Best’s rating methodology for life and annuity insurers is a comprehensive and structured process that evaluates an insurer’s balance sheet strength, operating performance, business profile, and risk management practices. The Financial Strength Rating (FSR) serves as a key measure of an insurer’s ability to meet its obligations, while the Best’s Capital Adequacy Ratio (BCAR) offers a detailed look at capital adequacy in relation to risk. By understanding the BCAR formula and how AM Best assesses different insurers, consumers and investors can make informed decisions about the financial stability of life and annuity providers. The examples provided show how BCAR assessments can vary, reflecting the unique capital positions and risks of each insurer. Annuity buyers and policyholders should consider both FSR and BCAR when evaluating the safety of their long-term financial investments.
