How AIG IUL Policies Work, and Who They Actually Fit

What AIG IUL Actually Is (and Who It's Actually For)

AIG IUL products sit at a specific intersection: permanent life insurance with cash value growth tied to a market index, a floor that prevents losses in down years, and a cap that limits upside in strong ones. For most retail buyers, the pitch stops there. For someone at $5M+ net worth, the relevant questions are different: does this structure solve a problem your other tax vehicles cannot, and at what cost?

The short answer is that AIG IUL can be a legitimate planning tool in narrow circumstances, particularly around estate tax exposure and tax-bracket arbitrage in retirement. It is not a superior wealth accumulation vehicle for most high-net-worth individuals who still have access to tax-advantaged alternatives. The sections below lay out the mechanics, the real costs, and the specific scenarios where the math actually works.

How AIG IUL Policies Work: The Mechanics Behind Index Crediting

AIG's indexed universal life products are issued through Corebridge Financial, the life and retirement division that AIG spun off as a public company. AM Best maintains a financial strength rating on Corebridge that reflects its ability to meet long-term policyholder obligations, which matters when you are committing to a 20- or 30-year contract.

The core mechanic: your premium, net of insurance costs and fees, funds a cash value account. At the end of each crediting period (typically one year), the insurer credits interest based on the percentage change in a chosen index, subject to a cap on the upside and a floor (usually 0%) on the downside. You do not own the underlying index. You own a contractual promise from the insurer to credit interest according to a formula.

IRC Section 7702 governs whether the contract qualifies as life insurance for tax purposes. If it does, cash value grows income-tax-deferred and the death benefit passes income-tax-free. If cumulative premiums exceed the seven-pay test threshold under IRC Section 7702A, the policy becomes a Modified Endowment Contract (MEC), which eliminates tax-free loan treatment and subjects distributions to ordinary income tax plus a 10% penalty before age 59½.

Properly structuring an IUL policy to avoid MEC status while maximizing cash value is not optional fine print. It is the central design decision that determines whether the tax benefits materialize at all.

AIG IUL Product Lineup: Max Accumulator+ and Value+ Protector

AIG's two primary IUL products serve different objectives, and the distinction matters before you spend time on illustrations.

Max Accumulator+ IUL is designed for cash value accumulation. The policy is structured to minimize the death benefit relative to premium, keeping cost-of-insurance charges low and directing more of each dollar toward the cash value account. This is the product relevant to retirement income planning or supplemental tax-free income strategies.

Value+ Protector IUL prioritizes death benefit stability. It is better suited to estate planning applications where the primary goal is delivering a guaranteed or near-guaranteed death benefit rather than maximizing cash value growth.

Neither product publishes fixed cap rates or participation rates in marketing materials, because the insurer retains the contractual right to change them. Current S&P 500-linked segments on AIG IUL products carry cap rates in roughly the 9% to 12% range, consistent with the broader IUL market. Participation rates on some indexed strategies run 70% to 90%. Both figures can be reduced by the insurer at any time in response to changes in interest rates or options costs.

That last point is not a footnote. Society of Actuaries research has documented that insurers have historically reduced cap rates during sustained low-rate environments, which directly compresses the return profile over a 20- to 30-year horizon. A policy illustrated today at a 10% cap could be operating at a 6% cap a decade from now.

The 2022 update to NAIC Actuarial Guideline 49-A addressed this by capping the maximum illustrated crediting rate at a more conservative benchmark, reducing many illustrated rates from the 6% to 8% range previously common to figures closer to 5% to 6%. Illustrations are now more honest. They are still not guarantees.

What Are the Cap Rates and Participation Rates on AIG IUL Policies?

The table below summarizes the key crediting parameters to compare across AIG's primary IUL indexing options. These figures reflect current market conditions and are subject to change.

The ML Strategic Balanced Index and PIMCO Global Optima Index use uncapped structures with a spread or participation rate instead of a hard cap. These proprietary indices typically include volatility controls that reduce allocation to equities when market volatility rises, which dampens both downside and upside relative to a pure equity index. The volatility-control mechanism is why these indices can offer higher participation rates without a cap: the insurer's options cost is lower because the index itself is less volatile.

Understanding how universal life interest rates work across these crediting structures is prerequisite knowledge before comparing illustrated returns across carriers.

The Pros and Cons of AIG IUL for High-Net-Worth Individuals

The standard IUL pitch emphasizes three benefits: downside protection, tax-deferred growth, and tax-free income via policy loans. All three are real. All three come with conditions that the retail pitch glosses over.

What works:

• The 0% floor means a year like 2022, when the S&P 500 dropped roughly 18%, credits zero rather than a loss. Over a long accumulation period, avoiding large negative years has genuine mathematical value.
• Policy loans are income-tax-free under IRC Section 72(e) as long as the policy remains in force. For a high earner in a 37% federal bracket, tax-free access to cash value in retirement has real value if the alternative is drawing from a taxable account.
• In states like Texas and Florida, life insurance cash value carries strong creditor protection. For business owners or professionals with liability exposure, this is a legitimate asset protection consideration.
• LIMRA data confirms that IUL has been among the fastest-growing permanent life insurance categories by premium volume, reflecting genuine demand from advisors and clients who find the downside protection feature valuable.

What doesn't:

• Morningstar analysis has highlighted that internal cost-of-insurance charges, administrative fees, and surrender charges in permanent life products can significantly erode net returns, particularly in the early policy years. A policy that looks attractive on a 30-year illustration can look poor on a 10-year horizon.
• The tax-free income narrative has a critical failure mode: if the policy lapses while loans are outstanding, the entire outstanding loan balance becomes immediately taxable as ordinary income in the year of lapse. For someone who has borrowed $500,000 or more over decades, that is a seven-figure tax event in a single year.
• Cap rates are not contractually locked. The illustrated upside is not the guaranteed upside.

The legitimacy concerns surrounding IUL products are often overstated in online commentary, but the fee and illustration concerns are not. The product is legitimate. The sales process around it frequently is not.

IUL vs. Term + Index Fund vs. Mega Backdoor Roth: Which Works for $5M+ Investors?

This is the comparison that most IUL illustrations deliberately avoid. For a 45-year-old in excellent health seeking $2 million in coverage, a 20-year level term policy typically costs $2,000 to $4,000 annually. A comparable death benefit inside an IUL may require $20,000 to $40,000 or more in annual premium to fund adequately.

The premium difference, invested in a low-cost S&P 500 index fund, would likely produce a larger liquid net worth after 20 years than the IUL cash value after fees, caps, and cost-of-insurance charges. Vanguard's foundational research on investment costs demonstrates that fee drag compounds significantly over long time horizons, and IUL all-in costs (including cost of insurance, administrative charges, and the implicit cost of the cap) are materially higher than a low-cost index fund.

The term-plus-invest strategy wins on accumulation for most scenarios. IUL wins in specific cases: estates with tax exposure, situations where creditor protection matters, and retirement income planning where the investor has exhausted other tax-free vehicles. Comparing IUL versus annuity options adds another dimension for those focused on retirement income specifically.

Should High-Net-Worth Individuals Use IUL for Estate Planning?

This is where the analysis shifts most clearly in IUL's favor, and it is the application that the Journal of Financial Planning identifies as the primary value proposition for high-net-worth clients: estate liquidity and tax-efficient wealth transfer rather than cash value accumulation.

The federal estate tax exemption sits at $13.61 million per individual in 2024. Under the Tax Cuts and Jobs Act, that exemption is scheduled to sunset after December 31, 2025, reverting to approximately $7 million (inflation-adjusted). An individual with a $10 million estate who takes no action before the sunset could face unexpected estate tax exposure on $3 million or more at a 40% rate.

An Irrevocable Life Insurance Trust (ILIT) holding a permanent life insurance policy removes the death benefit from the taxable estate entirely. The ILIT owns the policy; the insured's estate does not. The death benefit passes to trust beneficiaries free of estate tax and income tax.

For this application, the relevant question is not whether IUL beats a term-plus-invest strategy on accumulation. It is whether a permanent death benefit, sized to cover projected estate tax liability, is worth the premium cost. In many cases for estates in the $7M to $20M range, it is.

The TCJA sunset at the end of 2025 makes this a time-sensitive planning conversation. Gifting strategies, ILIT funding, and policy underwriting all take time. Waiting until 2026 to start the conversation is a planning failure.

The tax implications of IUL insurance extend beyond the death benefit, and your estate attorney and CPA need to be in the room when this structure is designed.

How IUL Policy Loans Can Become Taxable: The Risk Nobody Leads With

The tax-free loan feature is real. The failure mode is also real, and it deserves more than a footnote.

Under IRC Section 72(e), distributions from a life insurance policy are subject to LIFO treatment: gains come out before basis. Policy loans are not treated as distributions while the policy remains in force, which is why they are income-tax-free. The moment the policy lapses with outstanding loans, the IRS treats the lapse as a distribution. The entire outstanding loan balance, to the extent it exceeds your cost basis in the policy, becomes ordinary income in the year of lapse.

For a policyholder who has borrowed $600,000 over 20 years against a policy with a $200,000 cost basis, a lapse generates $400,000 of ordinary income in a single year. At a 37% federal rate plus state income tax, that is a $150,000 to $200,000 tax bill that arrives with no warning and no ability to spread it across years.

Policies lapse for three reasons: market underperformance reduces cash value below the loan balance, the insurer reduces cap rates and the policy underperforms its illustration, or the policyholder stops paying premiums. All three are more likely over a 30-year horizon than a 10-year illustration suggests.

Active policy monitoring, periodic premium top-ups, and a clear understanding of the minimum cash value required to support outstanding loans are not optional for anyone using this strategy. Understanding IUL surrender charges is part of the same due diligence: surrendering a policy with loans outstanding triggers the same tax event as a lapse.

IUL Cost Structure: Where the Money Goes in Years 1–20

The internal cost structure of an IUL policy is not disclosed in a single line item. It is distributed across several charges that compound over time.

The cost-of-insurance charge deserves particular attention. COI is calculated on the "net amount at risk," which is the difference between the death benefit and the cash value. In the early years of a Max Accumulator+ policy, when cash value is low relative to the death benefit, COI charges are high. As cash value grows and the net amount at risk shrinks, COI charges decline. This is why the accumulation story only works if you hold the policy long enough for COI to become a smaller fraction of the total.

Morningstar's analysis of internal policy charges confirms that these costs can significantly erode net returns compared to a buy-term-and-invest-the-difference strategy, particularly in the first 10 years. The break-even horizon for most IUL policies, relative to term-plus-invest, is typically 15 to 20 years or longer.

Maximizing returns with max-funded IUL strategies requires minimizing the death benefit to the lowest level allowed under IRC Section 7702, which reduces the net amount at risk and therefore the COI charges. This is a design choice, not a default.

How AIG IUL Compares to Competitors

AIG is not the only carrier worth evaluating. The table below compares key parameters across carriers that frequently appear in high-net-worth IUL discussions. Note that cap rates and participation rates change frequently; verify current figures directly with each carrier.

AM Best ratings reflect financial strength, not product quality. A carrier with an A+ rating issuing a poorly designed product is still a poorly designed product. The rating matters for counterparty risk over a 30-year contract. Product design matters for whether the economics work.

Fidelity & Guaranty's IUL reviews offer a useful data point on a carrier that competes primarily on cap rates and is worth including in any multi-carrier comparison.

Legal and Regulatory Risks in the IUL Space

The legal controversies in the IUL space are not hypothetical. Several major carriers have faced litigation over illustration practices, specifically allegations that illustrated crediting rates were materially misleading relative to what policyholders could realistically expect given the insurer's historical cap rate reductions.

NAIC Actuarial Guideline 49-A, updated in 2022, directly addressed this by requiring more conservative illustration benchmarks. The practical effect was that policies illustrated at 7% or 8% crediting rates before 2022 now illustrate at 5% to 6%. For policies already in force that were sold on pre-AG49-A illustrations, the gap between illustrated and actual performance is a live issue.

For a $5M+ buyer committing $30,000 to $50,000 annually to an IUL policy, the due diligence standard should match what you would apply to any other long-duration financial commitment. That means reviewing the carrier's historical cap rate changes, not just current caps; stress-testing the illustration at 4% and 5% crediting rates, not just the illustrated rate; and confirming the policy design avoids MEC status under IRC Section 7702A at your intended funding level.

Your insurance attorney and CPA need to review the policy contract, not just the illustration. The illustration is a marketing document. The contract is what the insurer is actually obligated to deliver.
