Participating Whole Life Dividend Scale in a Falling-Yield Environment
A mutual insurer's participating whole life block has $2.1 billion of reserves and $180 million of asset shares. The board is considering the 2025 dividend scale. Current dividend interest rate is 4.2%, but new money yields are 3.1% and the portfolio's book yield is 3.8%. Mortality has been favourable (95% of pricing) and expenses are 4% above pricing. The company uses a three-factor dividend method: interest, mortality, and expense. The dividend scale has not changed for three years, and policyholder reasonable expectations (PRE) are a regulatory consideration. Lapses have increased among policies with lower dividends, and the sales force wants a stable scale. The chief actuary must recommend a scale that is fair across cohorts and sustainable.
1. Analyze whether the 4.2% dividend interest rate is sustainable.
Read the worked answer
The 4.2% rate exceeds the portfolio book yield of 3.8% and new-money yield of 3.1%. Unless the portfolio contains high-yielding assets or capital gains that can be harvested, the current scale is likely to transfer surplus to policyholders faster than asset shares support. Asset shares are $180 million against reserves of $2.1 billion; the ratio is low, but reserves are not the same as asset shares. The relevant test is whether the policy-level asset share can fund the illustrated dividends and terminal dividend.
With new money at 3.1%, the long-term portfolio yield will drift down; a 4.2% interest component is not sustainable. Mortality at 95% and expenses at 104% provide only small offsets. I would model the portfolio yield decline and set the interest component closer to 3.5–3.7%, with smoothing rather than an abrupt cut.
2. Recommend changes to the dividend scale and explain cohort fairness and PRE.

I would reduce the dividend interest rate gradually, for example from 4.2% to 3.9% for 2025 and signal further reductions. Use asset share testing by cohort; older cohorts with higher guaranteed mortality charges may need different treatment. The three-factor method should show the interest, mortality and expense contributions explicitly.
To respect PRE, communicate the change with rationale, avoid retroactive cuts, and maintain a competitive but sustainable scale. If lapses are rising among lower-dividend policies, target retention efforts rather than propping up the scale. Consider a terminal dividend policy that shares accumulated surplus fairly. Fairness means not using new-business subsidies to support old scales. The board should approve a principle: dividends reflect asset share experience over time, smoothed.
3. Discuss the risks if the scale is not changed.
Read the worked answer
Risks include asset share depletion, cross-subsidy from capital, reduced solvency, and future sharp cuts that harm PRE. If the insurer keeps 4.2%, it may attract sales but write unprofitable business; lapse experience may become volatile as sophisticated policyholders compare dividends. Regulatory scrutiny may increase if illustrations are not supportable.
In a mutual, the cost falls on remaining policyholders and capital. A delayed correction could force a larger, more disruptive cut later. There is also reinvestment risk: selling long-duration guarantees at 4.2% when new money is 3.1% creates a negative spread. The board should act early and explain the smoothing.
