In 2018, AM Best affirmed the Financial Strength Rating (FSR) of "A" (Excellent) and the Long-Term Issuer Credit Ratings (Long-Term ICR) of “a+” for the primary life insurance subsidiaries of American International Group, Inc. (AIG). This rating carried a stable outlook, reflecting the group’s very strong balance sheet, adequate operating performance, and favorable business profile.
For many policyholders and financial planners, looking back at the 2018 financial standing of AIG is a critical exercise in understanding the long-term stability of life insurance contracts. Life insurance is a decades-long commitment; therefore, the historical consistency of a carrier's financial health provides essential context for the security of death benefits and cash value accumulations. In 2018, AIG’s life and retirement segment remained a cornerstone of the global insurance market, even as the parent company continued its multi-year restructuring process following the 2008 financial crisis.
The Significance of AM Best Ratings in the Life Insurance Sector
AM Best is a credit rating agency that specializes exclusively on the insurance industry. Unlike broader agencies that cover various corporate sectors, AM Best focuses on an insurer’s ability to pay claims, debts, and other financial obligations. For a life insurance policyholder, this rating is the most significant indicator of whether the company will have the liquidity to pay a death benefit thirty or forty years into the future.
The 2018 rating of "A" (Excellent) placed AIG in the top tier of insurance providers. While there are higher ratings—specifically A+ (Superior) and A++ (Superior)—an "A" rating signifies a "Very Strong" ability to meet ongoing insurance obligations. In the context of 2018, this rating was a signal to the market that AIG’s life insurance units had successfully distanced themselves from the volatility of the previous decade.
How AM Best Evaluates Life Insurers
To arrive at the 2018 rating for AIG, AM Best utilized a comprehensive building-block approach. This involves a deep dive into several qualitative and quantitative factors:
- Balance Sheet Strength: This measures the adequacy of an insurer’s capital relative to the risks it underwrites. It includes an analysis of reinsurance programs, investment quality, and reserve adequacy.
- Operating Performance: AM Best examines whether the company is actually profitable. For AIG in 2018, this involved looking at the premiums collected versus claims paid and the expenses associated with running the life insurance business.
- Business Profile: This considers the company’s market position, the diversity of its products (such as term life, universal life, and annuities), and its distribution channels.
- Enterprise Risk Management (ERM): This evaluates how well the company identifies and mitigates potential risks, ranging from market downturns to catastrophic mortality events.
Detailed Breakdown of the 2018 AIG Life & Retirement Ratings
In 2018, the ratings specifically applied to the members of the AIG Life & Retirement Group. This group included several key legal entities that issued the actual life insurance policies and annuity contracts.
The Core Subsidiaries Involved
The AM Best "A" (Excellent) rating was primarily directed at the following entities:
- American General Life Insurance Company (AGL): The primary issuer of life insurance products across most of the United States.
- The United States Life Insurance Company in the City of New York (US Life): The entity responsible for issuing policies within the state of New York.
- Variable Annuity Life Insurance Company (VALIC): A leader in the 403(b) and retirement plan market, focusing on tax-qualified retirement plans.
By affirming the "A" rating for these specific units, AM Best acknowledged that while the parent company (AIG Inc.) was a massive global conglomerate with various moving parts, the life insurance "bucket" was structurally sound and well-capitalized.
The "Stable" Outlook Explained
An "outlook" is a trend indicator. In 2018, the Stable outlook meant that AM Best did not anticipate changing the rating in the near term. This was a crucial vote of confidence because it suggested that AIG's strategic shifts—which included selling off non-core assets and focusing on "modular" business units—were yielding predictable results.
Factors Influencing AIG’s 2018 "A" Rating
Several internal and external factors contributed to AIG maintaining its "Excellent" status during the 2018 fiscal year. Understanding these factors helps clarify why the company did not reach the "Superior" (A+) level at that time, but also why it remained far above "Fair" or "Marginal" levels.
1. Capitalization and Liquidity
In 2018, AIG Life & Retirement maintained a capital position that AM Best categorized as "Very Strong." This was measured by the Best’s Capital Adequacy Ratio (BCAR). The company held significant reserves to cover its long-term liabilities, particularly in its interest-sensitive lines like fixed annuities and universal life insurance.
2. Market Dominance and Diversification
AIG was one of the largest life insurers in the United States by market share in 2018. Their product suite was highly diversified, including:
- Term Life Insurance: Providing affordable coverage for set periods.
- Index Universal Life (IUL): Offering cash value growth tied to market indices.
- Annuities: Both fixed and variable options for retirement income.
- Group Benefits: Life and disability insurance provided through employers.
This diversification meant that if one segment of the market underperformed (for example, if low interest rates hurt fixed annuity margins), other segments (like mortality-based term life insurance) could provide a buffer.
3. Investment Portfolio Quality
AIG’s investment strategy in 2018 was focused on high-quality, fixed-income securities. However, like many of its peers, the company faced the challenge of a "low-for-long" interest rate environment. This pressure on investment yields was one of the reasons the rating remained at "A" rather than moving higher, as the company had to work harder to generate the returns necessary to support long-term guarantees.
4. Integration and Parental Support
While the life insurance units were strong on their own, AM Best also considered their role within the broader AIG Inc. framework. The 2018 rating reflected a "neutral" to "positive" impact from the parent company, noting that the Life & Retirement segment was a significant contributor to the parent’s overall earnings and benefited from the global brand and shared resources.
Comparing AIG to Industry Peers in 2018
To understand the value of the "A" rating, it is helpful to compare AIG’s 2018 standing with other major players in the life insurance space during the same period.
| Insurance Carrier | 2018 AM Best FSR | 2018 Outlook |
|---|---|---|
| AIG (Life & Retirement) | A (Excellent) | Stable |
| MetLife | A+ (Superior) | Stable |
| Prudential Financial | A+ (Superior) | Stable |
| Northwestern Mutual | A++ (Superior) | Stable |
| New York Life | A++ (Superior) | Stable |
| Lincoln National | A+ (Superior) | Stable |
| Transamerica | A (Excellent) | Stable |
As the table demonstrates, AIG was positioned among the "Excellent" tier. While legendary mutual companies like Northwestern Mutual and New York Life held the "Superior" spots, AIG’s "A" rating was consistent with other massive, publicly traded multi-line insurers. The "A" rating indicated that AIG was a safe bet for policyholders, even if it wasn't at the absolute pinnacle of the AM Best scale.
The Long-Term Perspective: 2018 to 2026
From our current vantage point in 2026, the 2018 rating serves as a historical benchmark for AIG’s transition. Shortly after 2018, AIG began the process of separating its Life & Retirement business into a standalone entity, which eventually became Corebridge Financial.
The stability noted in the 2018 AM Best report was a precursor to this successful spin-off. By maintaining an "A" rating during a period of corporate reorganization, AIG demonstrated that the underlying insurance obligations were insulated from the parent company's structural changes. For a policyholder who purchased a 20-year term policy in 2018, the "A" rating was the first sign of the reliability that has continued through the company’s evolution into the mid-2020s.
Why 2018 Specifically Matters
The year 2018 is often cited in financial reviews because it represented a "normalization" period for AIG. It was the year when the company’s "New AIG" strategy, led by then-CEO Brian Duperreault, began to take firm hold. For life insurance consumers, this was the year when concerns regarding the 2008 bailout finally faded into the background, replaced by a focus on standard insurance fundamentals like underwriting discipline and expense management.
Practical Guidance for Policyholders
If you are reviewing an AIG life insurance policy issued around 2018, or if you are looking at historical data to gauge the company’s reliability, keep the following points in mind:
- Check the Specific Issuing Company: Remember that "AIG" is the brand. Your actual policy is likely with American General Life Insurance Company. Always verify the rating for the specific legal entity named on your policy documents.
- Understand the Rating Scale: An "A" rating from AM Best is a high-grade investment rating. It is not "average." On the AM Best scale, "A" is the third-highest possible rating out of 16 categories.
- Monitor Current Ratings: While the 2018 rating was "A," ratings are updated annually. In 2026, you should look for the current rating of Corebridge Financial (the successor to AIG Life & Retirement) to ensure that the "Excellent" standing has been maintained.
- Focus on the Claims-Paying Ability: Ratings are not a guarantee of performance for variable sub-accounts, but they are a strong indicator that the company will be able to pay the guaranteed death benefit and fixed interest credits.
Frequently Asked Questions
What does an "A" rating from AM Best actually mean?
An "A" (Excellent) rating is assigned to companies that have, in AM Best’s opinion, an excellent ability to meet their ongoing insurance obligations. It is considered a "Secure" rating. In 2018, this meant that AIG had the capital and liquidity necessary to handle even significant economic downturns without failing its policyholders.
Did AIG's 2018 rating affect the cash value of my life insurance?
The AM Best rating reflects the insurer's financial strength, not the performance of individual investment options within a variable life policy. However, for whole life or universal life policies with guaranteed interest rates, the "A" rating provided assurance that the company would be able to honor those interest guarantees over the long term.
Why wasn't AIG rated A++ in 2018?
Most "Superior" (A+ or A++) ratings are reserved for companies with exceptionally high levels of capital and very little debt. In 2018, AIG was still carrying a higher debt-to-equity ratio than some of its peers as it concluded its restructuring. Additionally, its historical volatility during the 2008 crisis required several years of "Stable" performance to regain the highest possible ratings.
How often does AM Best update these ratings?
AM Best typically reviews and updates its ratings annually. However, they may issue "Rating Actions" at any time if there is a significant event, such as a major acquisition, a natural disaster with high claims, or a change in corporate leadership. The 2018 affirmation was part of their standard annual review cycle.
Is an "A" rating enough for a 30-year term policy?
Yes, an "A" (Excellent) rating is generally considered very safe by financial advisors. While some prefer "Superior" rated companies for extremely long-term obligations, a company with an "A" rating and a "Stable" outlook has a statistically very low probability of default.
Final Recommendation
When evaluating the AIG 2018 AM Best financial strength rating, it is clear that the company was in a position of "Excellent" health. For those managing a life insurance portfolio, the 2018 "A" rating should be viewed as a sign of successful recovery and a commitment to policyholder security.
Next Steps: If you currently hold an AIG or American General policy, you should verify its current 2026 rating. You can do this by visiting the AM Best website or checking the Corebridge Financial Investor Relations page. If the rating remains in the "A" range or higher, your policy continues to be backed by a carrier with a strong financial foundation. If you are considering a new policy, use the 2018 data as proof of the company's historical resilience during periods of corporate change.
