The Irrevocable Pension Commutation
Client: 60, retiring in March after 34 years in the civil service. At retirement she must make a once-and-final election: a lump sum of HK$8.4m, or a monthly pension of HK$38,000 for life, with 50% continuing to her spouse (58) if she dies first. The pension is not indexed to inflation. Neither option is taxable in Hong Kong. She owns her flat outright (HK$4.1m), has HK$1.9m in MPF/ORSO and HK$0.8m cash. Her spouse draws HK$11,000 a month from his own scheme plus irregular income from a small business. Her mother lived to 94 and spent four years in residential care; her father died at 68 of a heart attack. She wants certainty of income but also wants to leave something to two grandchildren. She asks you which option gives her "more money".
1. Show her what the comparison actually turns on. Provide a break-even, an implied return, and explain why the larger nominal total is not the test.

Break-even. HK$8.4m ÷ (HK$38,000 × 12 = HK$456,000) = 18.4 years. She would be about 78 before cumulative payments equal the lump sum - and that ignores the time value of money, so the true break-even is later.
Implied return on the pension (treating the lump sum as the price of the annuity):
- Death at 80 (20 payments): IRR ≈ 0.7%
- Death at 85 (25 payments): IRR ≈ 2.5%
- Death at 90 (30 payments): IRR ≈ 3.5%
The survivor benefit lifts these slightly but does not change the shape.
Why nominal totals mislead. Because the pension is not indexed, a 2.5% inflation assumption turns the "2.5% at 85" case into roughly a zero real return. So the correct question is not "which total is bigger" but "can I beat about 2.5–3.5% nominal, after fees, with acceptable risk, over my own lifetime?" A short-dated high-grade HK$ portfolio might credibly earn 3.5–4%, which beats the pension if she dies before ~90 and loses to it if she lives longer.
The real trade: the lump sum is inheritable, flexible and can fund care; the pension is pure longevity and market-risk insurance that cannot be outlived or mis-sold. Frame it as buying insurance versus self-insuring, not as an investment contest.
2. Beyond the arithmetic, which factors should decide the recommendation, and how would you frame the advice?

Four decisive factors, in order:
- The care-cost tail. Her mother needed four years of residential care. A 2.5%-inflation care cost of HK$40,000 a month today is roughly HK$51,000 in ten years; four years would exceed HK$2.5m. That is a lump-sum need the pension cannot meet - but it is also the reason not to hand a large sum to an unsophisticated investor under pressure.
- Longevity and survivor protection. Female life expectancy at 60 in Hong Kong is comfortably into the late 80s; the 50% survivor benefit protects her spouse if she dies first, and the full pension continues to her if he dies first. The lump sum offers no such asymmetry.
- Behavioural suitability. Her stated wish is certainty. A HK$8.4m lump sum in the hands of a risk-averse, non-expert investor with two adult children taking an interest in the inheritance is a foreseeable loss.
- The inheritance goal. The pension dies with her (assuming no guarantee period).
How I would put it: the pension buys the certainty she says she wants and protects against the one outcome she has personally witnessed, long-term care. I would recommend the pension plus a term or whole-life policy funded from her MPF/ORSO and cash to create the grandchildren's inheritance and, if possible, a care reserve - rather than taking the lump sum and trying to manufacture income certainty from it.
I would put the two IRRs on one page, in front of her and her spouse, and record the election rationale, because this decision is not reversible.
3. Her spouse says "take the lump sum, I'll invest it". What must you establish before endorsing that?

Evidence, not assurances.
- Track record and capacity: has he managed a seven-figure portfolio through a drawdown? What did he hold in 2022, and what did he do? A plan that assumes 5%+ returns is a plan that fails in the first bad year.
- Withdrawal arithmetic: HK$8.4m supporting, say, HK$500,000 a year of household spending is a 6% withdrawal rate. That is not a managed portfolio, that is a countdown. The pension pays HK$456,000 with no market risk; matching it from capital requires roughly HK$13m at 3.5%.
- Sequence risk: two consecutive negative years early in retirement permanently impairs a 6% drawdown strategy. The pension cannot be impaired.
- Ownership and estate: if the lump sum is invested in his name or jointly, she loses control; if they separate or he predeceases her having lost money, she has no recourse. The pension cannot be spent by anyone else.
- The asymmetry he is ignoring: if both die early, the lump sum leaves the children a large estate; the pension leaves nothing. That is the price of the insurance, and it is her decision, not his.
What would change my view: a written investment policy, a professionally managed and fee-disclosed portfolio targeting a sustainable 3.5% withdrawal, a separately owned reserve for care, and her demonstrable understanding and agreement - plus a documented discussion of what happens if returns fall short. Absent those, the commutation is transferring longevity risk from a scheme that can pool it to a household that cannot.
