Why Indexed UL Illustration Assumptions Matter in Life Settlement Pricing

Indexed universal life (IUL) policies add a layer of complexity to life settlement underwriting because policy performance depends on crediting methods, caps, participation rates, spreads, and other moving parts that can change over time. Investors are not simply buying a face amount—they’re buying a set of future cash-flow risks tied to how the policy is illustrated and how it is likely to behave under realistic conditions.

That’s why institutional buyers typically request multiple in-force illustrations using specific assumptions. Their goal is to understand lapse risk, premium requirements, and how sensitive the policy is to changes in credited interest.

What Investors Are Trying to Learn From IUL Illustrations

Before an investor commits capital, they generally want to answer a few key questions:

• How much premium is required to keep the policy in force through maturity?
• How sensitive is the policy to lower credited interest over time?
• Are charges and funding levels stable, or is the policy at risk of rapid value erosion?
• How do loans, withdrawals, riders, and death benefit options affect sustainability?

Illustration assumptions are the lens through which these questions get modeled.

Typical Illustration Assumptions Investors Request for Indexed UL

1) “Current Assumption” In-Force Illustration

This is the baseline carrier illustration using current cap rates, participation rates, spreads, and current policy charges. Investors use it to understand how the policy looks under today’s carrier assumptions and current funding patterns.

Even though it’s the standard carrier output, investors rarely treat it as “the answer.” They treat it as a starting point.

2) Conservative Crediting Rate Scenario (Lower Return)

Because IUL credited interest can vary and may be constrained by caps/spreads, investors often request a lower credited interest scenario to stress-test sustainability. This is designed to answer: “If credited interest is weaker than illustrated, does the policy still stay in force without a funding shock?”

In practice, this often means an illustration with a materially lower assumed crediting rate than the current assumption run.

3) “Zero or Floor” Scenario (Worst-Case Stress Test)

Some investors request an extreme stress case that assumes minimal credited interest (often approximating a floor). The point isn’t to predict the most likely future—it’s to quantify how quickly the policy would deteriorate in a harsh environment and how much premium would be required to prevent lapse.

This kind of scenario is also useful when the policy is already thinly funded or has a history of unstable performance.

4) Alternative Indexing Assumptions (If Multiple Strategies Exist)

If the policy offers multiple crediting strategies or index allocations, investors may request illustrations based on different strategies—especially if certain allocations historically produce very different credited results or have different caps/spreads.

The goal is to avoid relying on a single strategy that looks favorable on paper while ignoring more conservative options that may be more realistic over time.

5) Level vs Increasing Death Benefit Option Modeling

In many UL designs, the death benefit option (Level vs Increasing) affects corridor requirements and internal charges. Investors often want illustrations that confirm which option is currently in force and how it impacts sustainability and premium requirements.

If changes are being considered, buyers may also want “what-if” illustrations showing how different options affect longevity of coverage.

6) Premium Pattern Variations (Minimum vs Target vs “Keep in Force”)

Investors often request runs that show different premium inputs, such as:

• Current premium pattern: based on what has actually been paid
• Minimum premium to keep in force: the smallest premium that avoids lapse under each crediting scenario
• Premium solve to age/maturity: a premium amount designed to carry the policy to a specified age or duration

These runs help quantify the buyer’s ongoing carry cost under different performance assumptions.

7) Loan and Distribution Assumptions (If Applicable)

If the policy has loans or distributions, investors typically want illustrations that reflect current loan balances and future loan interest mechanics. Loan drag can significantly increase lapse risk in IUL policies, especially when crediting underperforms.

Even when loans aren’t currently present, investors may request confirmation that no future distributions are assumed in the illustration so the model stays clean and comparable.

8) Charges and Policy Expense Transparency

Investors often look closely at cost of insurance charges, policy fees, rider charges, and how those costs scale over time. They may request illustrations that clearly show:

• Current COI rates and projected COI charges
• Policy fees and administrative charges
• Any rider fees that materially affect sustainability

Tip: For IUL, investors care less about the “illustrated upside” and more about the downside risk—how quickly the policy fails when crediting is weaker than expected.

A strong submission anticipates that by providing multiple scenarios upfront.

How Sellers and Advisors Can Make IUL Submissions “Investor-Ready”

• Request multiple in-force illustrations that include conservative crediting scenarios.
• Confirm current caps, participation rates, and spreads on the policy and note recent changes.
• Provide a clear premium history and current premium schedule (including next due date).
• Disclose loans, withdrawals, and any rider costs that affect performance.
• Ask the carrier for a run showing the premium needed to keep the policy in force under lower crediting assumptions.

The Takeaway: Assumptions Drive the Investor’s View of Risk

Indexed UL policies can be attractive in the secondary market, but their value is highly sensitive to crediting assumptions and expense dynamics. Investors typically request multiple illustrations because they want to see how the policy behaves under conservative conditions—not just under the carrier’s current illustrated rate.

If you’re preparing an IUL for market, providing the right set of assumption runs upfront can reduce rework, build buyer confidence, and lead to more reliable pricing.
