Participating Whole Life Dividend Scale Under Stress
A mutual insurer's participating whole life block contains 55,000 policies with $4.1 billion of face amount. The current dividend scale has a 5.4% dividend interest rate, but the net portfolio yield is 4.8% and expected to fall as reinvestment occurs at 4.2%. Mortality is 90% of expected and expenses are 108% of expected. Lapses are 3.2% versus 4.0% priced, so more policies remain in force and receive dividends. The dividend scale has not changed for three years, and agents are using it in sales illustrations. Surplus is $850 million, and the board wants to keep the scale to protect new-business competitiveness. The appointed actuary must advise on whether the scale is supportable under the company's dividend policy and illustration rules. A 50 basis point reduction would cut annual dividends by about $28 million and reduce new-business illustration values by 8-10%.
1. Assess the sustainability of the 5.4% dividend interest rate using the sources of surplus. What should the actuary recommend?
Read the worked answer
The 5.4% dividend interest rate is not the portfolio yield; it must be supported by the aggregate dividend contribution. The investment contribution is negative: 4.8% net yield versus a 5.4% scale is a 60 basis point shortfall, widening toward 120 basis points as reinvestment occurs at 4.2%. Mortality at 90% gives a gain, but expenses at 108% are a loss, and lapses at 3.2% versus 4.0% keep more dividend-paying policies in force, increasing the dividend liability. A 50 basis point cut saves about $28m annually and is consistent with the earned spread; maintaining the scale relies on future mortality and expense gains that are not yet demonstrated. Recommendation: reduce the scale by 50 basis points now, adopt a smoothed scale with a documented contribution method, and prohibit illustrations from assuming the old scale. If mortality gains prove durable, a smaller reduction can be restored later; they should not be used to fund an unsupported interest rate.
2. How should the company communicate and implement the change to limit policyholder and conduct risk?

Implement the reduction with advance written notice, a clear explanation that the scale reflects investment, mortality, expense, and persistency experience rather than a single year's result, and confirmation that contractual guarantees are unaffected. Update all illustration software and agent training before the effective date, and monitor field conduct because agents may resist a lower scale. Document the board's decision and the appointed actuary's contribution analysis. Consider smoothing future changes so policyholders are not exposed to abrupt swings, and preserve a competitive position through service and product design rather than an unsupported dividend rate. The conduct risk is highest if the old scale continues to appear in sales material after the board decision, so controls should include pre-approval of illustration inputs and a post-change audit.
