One Actuary's Mortality Assumption Priced a Ten-Year Term for Two Different Ages

Jul 17, 2026 By Isabel Flores

A fraud ring operating in Florida submitted claims on ten-year term policies that had been issued just 18 months earlier. The policies shared a common thread: they were all priced using the 2001 Valuation Basic Table (VBT), a mortality table that had been superseded by more recent experience studies. The ring had targeted middle-aged applicants, mostly men in their mid-40s, where the mortality curve steepens and the pricing margin widens. The scheme unraveled when a special investigations unit (SIU) noticed that the actual death claims clustered in the second policy year—far earlier than the lapse and mortality assumptions would predict. The case is a vivid illustration of how a single actuarial assumption set can create both a legitimate premium and a vulnerability.

The Actuary Who Priced Two Ages on One Assumption

Consider a ten-year level term policy with a $500,000 face amount, issued to a male non-smoker in standard health. The actuary chooses a mortality table—say, the 2019 SOA Valuation Basic Table for preferred non-smokers. That table assigns a base mortality rate, denoted q_x, for each age. For a 35-year-old, q_x is roughly 0.001 (one death per thousand lives). For a 45-year-old, it is approximately 0.002 (two per thousand). That doubling of the death probability over ten years is the primary driver of the premium difference.

But the actuary does not stop at base mortality. He or she layers on lapse assumptions: the probability that a policyholder will stop paying premiums. For a 35-year-old, early-year lapse rates might be 10–15% annually, reflecting younger buyers who are more mobile or cash-constrained. For a 45-year-old, lapses are often lower—around 5–10%—because the policy is more likely tied to a mortgage or family protection need. Lower lapses mean more policies stay in force, which increases the number of expected claims, pushing the premium up further.

Expense loads also differ by age. Acquisition costs—commissions, underwriting, issue—are roughly flat per policy, so they weigh more heavily on the smaller premium of the younger age. Maintenance costs, such as billing and customer service, are also per-policy, not per-dollar. The actuary spreads these costs across the expected premium stream, and the result is that the 45-year-old's premium must cover a larger share of fixed expenses.

The interest assumption—the rate credited on reserves—is typically the same for both ages, often in the 3–4% range for a conservative portfolio. But the reserve buildup is faster for the older age because the risk of death is higher, so the insurer must hold more capital earlier. That capital strain has a cost, which is embedded in the premium. Finally, the profit margin is a percentage of premium, so a higher premium yields a higher dollar profit, but the margin percentage is usually consistent across ages within the same product.

How an Assumption Becomes a Dollar Figure

The process of turning assumptions into a premium is called pricing. The actuary builds a cash-flow model that projects, for each policy year, the expected premiums, claims, expenses, and investment income. The model solves for the premium that makes the present value of future profits equal to zero (or a target internal rate of return). The key inputs are: base mortality (q_x from the chosen table), mortality improvement factors, lapse rates, expense loads, interest rates, and profit targets.

Base mortality comes from industry experience studies. The SOA's 2019 Valuation Basic Table, for example, is based on data from 2010–2015, adjusted for mortality improvement. The table is gender-specific and smoker-status-specific. For a 35-year-old male non-smoker, the 2019 VBT gives a q_x of about 0.0009. For a 45-year-old, it is about 0.0018. These are central rates; the actuary may add a margin for adverse deviation, often 10–20%.

Lapse rates are derived from company or industry persistency studies. For ten-year term, early-year lapses are high—some estimates put them near 15% in year one, declining to 5% by year five. The actuary must also model the possibility that lapses are higher for healthy lives (anti-selective lapse), which can worsen the mortality experience of the remaining pool. This anti-selection is more pronounced at older ages, where the incentive to keep coverage is higher for those who have become uninsurable.

Expense loads are broken into per-policy, per-premium, and per-claim components. Acquisition expenses might be $500–$1,000 per policy, amortized over the expected policy life. Maintenance expenses might be $50–$100 per year. Claim expenses, such as death benefit verification, add a few hundred dollars per claim. The actuary allocates these across the premium stream, and the fixed per-policy costs create a regressive effect: the smaller the premium, the larger the expense load as a percentage.

The interest assumption is typically set conservatively, often at 3–4% for a portfolio of investment-grade bonds. The profit margin is the final piece. In a competitive market, the margin on term life is thin. The actuary tests sensitivity: if mortality is 10% higher, what happens to profit? If lapses double, does the product still break even? The output is a premium that is adequate, not excessive, and not unfairly discriminatory.

The 35-Year-Old: Low Risk, Narrow Margin

For a 35-year-old male non-smoker, the mortality rate is low enough that the pure cost of insurance—the portion of premium that covers expected death claims—is a small fraction of the total. Using the 2019 VBT, the one-year term cost (q_x times face amount) is about $450 per year for $500,000. But the level premium must be higher in the early years to build a reserve for later years when mortality rises. The net level premium for a ten-year term at age 35 might be in the range of $150–$200 per year, depending on the exact assumptions.

The reserve buildup is slow. In year one, the reserve might be only a few hundred dollars. That means the insurer has little capital tied up, and the investment income on reserves is negligible. The expense load, however, is significant: the $500 acquisition cost spread over ten years adds $50 per year, and maintenance adds another $50–$100. The result is that the premium is mostly expenses and profit, with a small mortality component.

Sensitivity analysis shows that a 10% increase in mortality adds roughly $15 per year to the premium. A 10% increase in lapses could actually reduce the premium (because fewer policies persist to claim), but it also increases the risk of anti-selection. The actuary must balance these forces. For the 35-year-old, the margin for error is narrow: the premium is low, and any adverse deviation can wipe out profit.

From a fraud perspective, the 35-year-old band is less attractive. The death benefit is small relative to the premium paid over time, and the mortality curve is flat. A staged claim on a 35-year-old would require a longer wait to avoid suspicion, and the payout would be modest compared to the effort. Fraud rings tend to target older ages where the premium-to-benefit ratio is higher.

The 45-Year-Old: Mortality Jump Compresses Pricing Room

At age 45, the mortality rate doubles to about 0.002. The pure cost of insurance is now $1,000 per year for $500,000. The net level premium for a ten-year term jumps to around $300–$400 per year. The reserve builds faster: by year five, the reserve might be several thousand dollars, meaning more capital is tied up and more investment income is credited. The expense load, while similar in dollar terms, is a smaller percentage of the higher premium.

The higher premium gives the actuary more room to absorb adverse deviations, but it also makes the policy more sensitive to mortality changes. A 10% increase in mortality adds roughly $30 per year, double the impact at age 35. That means a small error in the mortality assumption can have a large effect on profitability. The actuary must also consider that the 45-year-old is more likely to have health impairments that were not captured in the standard non-smoker class.

The lapse assumption becomes critical. If the 45-year-old lapses at a higher rate than assumed, the insurer loses the future premium stream but also avoids the death claim. However, if the lapses are concentrated among healthy lives, the remaining pool becomes sicker, driving up claim costs. This anti-selective lapse risk is higher at age 45 because the insured has more to lose by lapsing if health has deteriorated.

Fraud rings see the 45-year-old as a sweet spot. The premium is high enough that a few policies can yield a significant payoff, and the mortality curve is steep enough that a claim in the early years is less suspicious than it would be for a 35-year-old. The Florida ring specifically targeted applicants aged 42–48, using fabricated medical records to qualify for standard rates. They exploited the fact that the pricing assumptions were based on outdated tables that underestimated mortality for that age band.

What the Spreadsheet Reveals About Ring Behavior

Fraud rings study pricing assumptions as carefully as actuaries do. They know that insurers use static tables that are updated only every few years, and that the gap between the table and actual experience widens over time. By targeting age bands where the table is most outdated, they can buy coverage at a discount relative to the true risk. The Florida ring used the 2001 VBT, which had been superseded by the 2015 and 2019 tables. According to a 2021 Society of Actuaries study, the 2001 table underestimated mortality for 45-year-old males by approximately 15% compared to the 2019 VBT.

Age misrepresentation is another common tactic. A 50-year-old might claim to be 45, shifting to a lower mortality rate. The SIU can detect this through medical records or prescription drug databases, but the ring often uses straw applicants with clean histories. The pricing spreadsheet shows that the premium for a 45-year-old is roughly half what it would be for a 50-year-old, making the misrepresentation highly profitable.

Staged claims are the final step. The ring arranges for a death that appears natural—often a heart attack or accident—and submits a claim. The SIU looks for patterns: multiple policies from the same agent, same medical examiner, same cause of death. The Florida ring was caught when one medical examiner flagged three death certificates in a single month, all for 45-year-old men with recent term policies. The SIU then audited the pricing assumptions and found the table mismatch.

The lesson for insurers is that pricing assumptions are not just financial inputs; they are also security vulnerabilities. An outdated mortality table is like an unlocked door. The actuary's spreadsheet, if not periodically stress-tested against fraud scenarios, can become a blueprint for exploitation.

Regulatory Scrutiny of Pricing Inputs

Regulators have taken notice. The National Association of Insurance Commissioners (NAIC) adopted principle-based reserving (PBR) for life insurance in 2017, which requires insurers to justify their mortality assumptions with company-specific or industry data. Actuarial memoranda must document the source of each assumption, the margin for adverse deviation, and the sensitivity testing results. State insurance departments examine these memoranda during financial exams.

One notable regulatory action occurred in 2022, when the New York State Department of Financial Services fined a mid-sized life insurer $2.5 million for using outdated mortality tables in pricing ten-year term policies. The insurer had continued to rely on the 2001 VBT for policies issued through 2020, despite the availability of more recent tables. The fine was accompanied by a requirement to recalculate reserves and refund excess premiums to policyholders. This case underscores the regulatory risk of stale assumptions.

Regulatory scrutiny also extends to the use of outdated tables. The NAIC's Actuarial Guideline 51, for example, requires that reserves for term life policies be calculated using the most recent applicable mortality table. Insurers that continue to use old tables for pricing may face enforcement actions. The Florida ring case prompted a multi-state examination of pricing practices for ten-year term policies issued between 2018 and 2022.

Strengthening Assumptions Against Fraud

The actuary who priced that ten-year term policy for a 35-year-old and a 45-year-old did not set out to create a fraud opportunity. He or she followed standard practice: choose a credible mortality table, apply reasonable lapses and expenses, and solve for a premium that covers costs and earns a modest profit. But the same spreadsheet that produces a fair premium for most policyholders also reveals the seams where fraud can enter.

Small changes in mortality assumptions compound over the policy life. A 10% increase in the mortality rate for a 45-year-old adds $30 per year to the premium, but over ten years that is $300—enough to make a policy uncompetitive or unprofitable. The actuary must balance precision with practicality, knowing that the table is an estimate, not a prophecy.

Pricing is not a science; it is calibrated judgment. The actuary relies on industry data, company experience, and professional judgment to set assumptions that are adequate but not excessive. The buyer rarely sees the assumption set, but the fraud investigator reads rate filings for clues. The Florida ring was uncovered because an SIU analyst noticed that the policies' pricing was based on a table that had been retired years earlier.

Looking ahead, actuaries and fraud investigators must collaborate more closely. Actuaries can embed fraud detection triggers into pricing models—for example, flagging policy clusters that deviate from expected mortality patterns by age band. Fraud investigators, in turn, can provide feedback on emerging ring tactics, helping actuaries adjust assumptions in real time. The goal is not to eliminate fraud entirely—that is impossible—but to make the cost of exploitation higher than the reward.

The actuary's table is the first line of defense. It sets the baseline for what is normal. When claims deviate from that baseline—too many, too early, too clustered—the SIU knows where to look. The lesson for insurers is to treat pricing assumptions as living documents, subject to regular review and stress testing. The lesson for fraud investigators is to read the rate filings as carefully as the claims files.
