Insurance Curator High-net-worth (HNW) estate planning in the United States increasingly relies on long-duration insurance solutions — survivorship (second-to-die) life policies, private placement life insurance (PPLI), and premium-financed structures — to transfer wealth, provide liquidity for estate taxes, and mitigate income and transfer taxes. Properly modeling mortality improvement and quantifying pricing risk are essential for advisors, actuaries, and trustees in high-tax jurisdictions like New York City, San Francisco Bay Area, Miami, and Dallas. This article explains actuarial frameworks, model choices, sensitivity testing, practical pricing implications, and market considerations — with actionable guidance for advisors working with HNW clients.
Why mortality improvement matters for HNW insurance strategies
- Mortality improvement is the observed reduction in mortality rates over time at given ages. Over decades this can materially change expected death benefits and pricing for long-dated policies.
- For survivorship and single-premium policies used in irrevocable life insurance trusts (ILITs) or estate liquidity strategies, small annual mortality improvements compound and can reduce insurer expected claims by a meaningful amount across policy lifetimes.
- Mis-specifying mortality improvement affects:
- Premium adequacy and single-premium sizing for funded strategies
- Reserve and capital requirements for carriers and lenders in premium-finance
- Valuation for estate inventories and transfer-for-value analysis

Actuarial models: deterministic vs stochastic approaches
HNW planning requires both deterministic and stochastic modeling:
-
Deterministic models
- Apply a single mortality improvement scale (e.g., SOA MP-2019/MP-2020) to base mortality (e.g., RP-2014/2015/2017) to produce best-estimate lifetables.
- Useful for pricing illustrations and regulatory/estate reporting.
-
Stochastic models
- Model mortality improvement as a random process (e.g., Lee-Carter with stochastic time factor, Cairns–Blake–Dowd (CBD) family) to quantify tail risk (longevity outperformance).
- Required for capital modeling, reinsurance negotiation, premium financing stress tests, and for lenders deciding collateral haircuts.
Table: common mortality improvement models and practical use
| Model | Strengths | Typical Use in HNW Planning |
|---|---|---|
| Deterministic SOA improvement scales (MP-2015/MP-2018/MP-2020) | Simple, transparent, industry-accepted | Pricing, policy illustration, estate valuation |
| Lee–Carter (stochastic) | Captures long-term trend + volatility | Longevity risk stress testing, reserving scenarios |
| Cairns–Blake–Dowd (CBD) | Focus on older ages (suitable for HNW older lives) | Pricing survivorship policies, reinsurance modelling |
| Cohort-enhanced models | Capture cohort effects (e.g., smoking cessation) | Specialized underwriting segments |
Quantifying pricing risk: sensitivity analysis & stress tests
Advisors and actuaries should run sensitivity analyses on the following drivers:
- Mortality improvement assumption (±25–100 basis points per year)
- Interest rate environment (discount rate for reserves and pricing)
- Lapse/behavioral risk (policy loans, partial surrenders)
- Underwriting classification (Preferred Best vs Standard vs Table-rated)
Illustrative sensitivity (example): survivorship UL face of $10M for a 62 / 60 healthy couple — single-premium sizing impact
| Assumption | Mortality improvement = 0.5% p.a. | Mortality improvement = 1.0% p.a. | Mortality improvement = 1.5% p.a. |
|---|---|---|---|
| Indicative single premium (illustrative range) | $2.2M | $2.45M | $2.75M |
| Relative change from 1.0% | -10% | base | +12% |
Notes: figures are illustrative to show sensitivity; actual carrier quotes vary by underwriting, product, and market. Use stochastic modeling to quantify tail probability (e.g., probability that policy lives exceed expected survival by >5 years).
Market pricing realities — carriers, product types, and indicative ranges
In the HNW market in the United States, a small set of carriers dominate large face-amount placements and survivorship business. Examples include:
- New York Life (strong whole life and participating products; conservative pricing and underwriting)
- Pacific Life (large presence in survivorship UL and private placement structures)
- Prudential, Lincoln Financial, and MassMutual (notable for UL/IUL and underwriting capacity)
Pricing tendencies:
- Mutual carriers (New York Life, MassMutual) often price conservatively and can offer participating whole life for clients seeking guarantees — annual premiums for participating whole life are typically higher than equivalent UL funding but provide stronger guarantees.
- Pacific Life and VitaLife-style carriers are active in single-premium survivorship UL and PPLI markets and can offer competitive single premium structures for HNW clients.
Indicative premium ranges (market rule-of-thumb; illustrative only):
- $10M survivorship UL for a 62/60 healthy couple (single premium): approximately $2.0M–$3.5M depending on carrier, crediting rate, and underwriting.
- $5M survivorship policy funded with annual premiums: annual premium range $120k–$300k depending on product and client age.

Always obtain firm illustrations from carriers (New York Life, Pacific Life, Prudential, Lincoln Financial) and run bidder competitions for large face amounts; pricing differentials of 10–30% between carriers are common once underwriting and crediting assumptions are considered.
Valuation & estate-tax interactions for HNW clients
- Mortality improvement assumptions feed directly into valuing insured interests for estate tax purposes. The discounting of expected death benefits and use of actuarial present values under IRC and Treasury rules require defensible mortality assumptions.
- When life insurance is in an ILIT or part of a premium-financed structure, valuation impacts estate tax outcome and lender covenants. See related topics on valuation: Valuing Life Insurance Interests for Estate Tax Purposes: Methods and Pitfalls, and how mortality assumptions affect valuation: Mortality Assumptions, and Their Impact on Policy Valuation.
- For premium-financed structures, collateral mark-to-market and stress-testing are essential to avoid forced sales or policy lapses; see Valuation Issues in Premium Financing: Collateral Mark-to-Market and Stress Testing.
Practical steps for advisors (New York, California, Florida, Texas focus)
- Use industry-accepted base mortality tables plus SOA improvement scales as your starting point; document the rationale.
- Require carrier-specific target crediting rates and guaranteed illustrations — compare across New York Life, Pacific Life, Prudential, and Lincoln Financial.
- Run stochastic longevity scenarios (Lee–Carter / CBD) to estimate capital and liquidity needs under tail outcomes — critical for Miami and NYC clients who may face state estate tax exposure and sophisticated creditor risk.
- For premium-financed acquisitions, require lender stress tests with explicit mortality improvement scenarios and put negotiated covenants on collateral haircuts.
- For ILIT-funded and PPLI structures, perform sensitivity analyses on:
- Mortality improvement ±0.25%–1.0% p.a.
- Interest rate shocks (down 200 bps / up 200 bps)
- Lapse shock (10% instantaneous lapse or 20% over 2 years)
Governance, documentation, and expert support
- Document model choice, data sources (SOA, CDC), and rationale for assumptions in engagement letters and estate workpapers.
- Use independent actuarial review for valuations that could be contested in probate or IRS scrutiny — expert witness and appraisal work may be necessary for large estates.
- Consider reinsurance or longevity swaps for very large, balance-sheet sensitive positions.
Conclusion
Modeling mortality improvement and pricing risk is not academic — it directly affects premium sizing, lender decisions, estate outcomes, and the durability of an HNW client’s insurance-based transfer strategy. For high-net-worth clients in jurisdictions like New York City, the Bay Area, Miami, and Texas, advisors should combine accepted deterministic scales (SOA), stochastic longevity modeling (Lee–Carter/CBD), carrier comparisons (New York Life, Pacific Life, Prudential, Lincoln Financial), and rigorous stress-testing to produce defensible, actionable plans.
