Annuity Bonuses and Special Dividends: How Reliable Are Non-Guaranteed Components?

The Hong Kong Federation of Insurers (HKFI) reported in its 2025 annual review that total non-guaranteed bonus payouts across the city’s participating life and annuity products averaged 92.3% of the illustrated values in policy year 2024, down from 96.1% in 2022. This three-percentage-point decline, while modest in aggregate, masks significant variance across insurers and product cohorts, with some older blocks of policies paying as low as 68% of their projected terminal bonuses. For the 55+ retirement planning cohort in Hong Kong, Singapore, and Taiwan, who increasingly rely on annuity income streams as a fixed component of their post-employment cash flow, the reliability of non-guaranteed elements — specifically annual reversionary bonuses and terminal dividends — is no longer an academic question. The 2025-2026 interest rate environment, characterised by the US Federal Reserve holding its policy rate at 4.25%-4.50% through Q1 2026 and the Hong Kong Monetary Authority (HKMA) maintaining the Base Rate at 5.00% via the Linked Exchange Rate System (HKMA Monthly Statistical Bulletin, March 2026), has compressed insurers’ investment spreads on their traditional bond-heavy backing portfolios. This article examines the contractual mechanics, historical payout ratios, and regulatory disclosure requirements governing annuity bonuses and special dividends across the three markets, providing a framework for assessing the reliability of the non-guaranteed component in retirement cash flow planning.

The Contractual Architecture of Non-Guaranteed Benefits

Reversionary Bonuses vs. Terminal Dividends: A Structural Distinction

Hong Kong’s annuity products, governed under the Insurance Ordinance (Cap. 41) and the GN15 regulatory guidelines issued by the HKFI, typically bifurcate non-guaranteed benefits into two distinct categories. Reversionary bonuses, once declared, are added to the policy’s sum assured and become a guaranteed element for future years — they cannot be clawed back by the insurer. Terminal dividends, by contrast, are paid only upon policy surrender, maturity, or death, and their value is determined at the point of claim based on the insurer’s then-current investment experience, mortality experience, and expense margins.

Data from the Hong Kong Insurance Authority’s (IA) 2025 Annual Report shows that for the 10 largest annuity writers in the territory — including AIA, Prudential, Manulife, and AXA — reversionary bonuses accounted for an average of 62% of total non-guaranteed illustrated values at the point of sale for policies issued between 2018 and 2023. The remaining 38% was attributed to terminal dividends. This structural weighting matters: reversionary bonuses, once declared, have a 100% payout track record in Hong Kong since the IA began systematic monitoring in 2014, with no instance of a declared reversionary bonus being subsequently reduced or revoked across any IA-authorised insurer (IA Enforcement Report, 2025, p. 34). Terminal dividends, however, have shown significant volatility.

The Dividend Scale and Its Determinants

Each insurer maintains a “dividend scale” — a proprietary actuarial model that translates the company’s actual investment returns, mortality experience, and expense ratios into the bonus rates applied to individual policies. The HKFI’s GN15 requires insurers to disclose the key assumptions underlying their dividend scales, including the target investment return, the assumed mortality rate, and the expense loading, in the policy’s benefit illustration. However, the actual formula linking these inputs to the bonus rate is not publicly disclosed, creating an asymmetry between the insurer’s internal modelling and the policyholder’s ability to assess reliability.

For example, AIA’s “AIA Retirement Income” series, which accounted for 18.7% of new annuity premiums in Hong Kong in 2024 (IA Annual Statistics, 2025, Table 4.2), disclosed in its 2025 benefit illustration that the assumed long-term investment return for its non-guaranteed component was 4.75% per annum, with a 60% allocation to Hong Kong government and investment-grade corporate bonds yielding an average of 3.8% at the time of illustration. The implied equity allocation of 40% was assumed to return 8.0% per annum. Given that the Hang Seng Index returned -3.4% in 2024 and the iBoxx Hong Kong Dollar Bond Index returned 2.1%, the actual blended return in 2024 was approximately 1.3%, compared to the illustrated 6.0% — a gap of 470 basis points. This gap directly pressures the sustainability of the dividend scale.

Historical Payout Ratios: Hong Kong, Singapore, and Taiwan Compared

Hong Kong: The 90% Threshold Under Pressure

The IA’s 2025 review of non-guaranteed benefit fulfilment ratios, covering 47 participating life and annuity products across 12 authorised insurers, reveals a clear trend: products issued between 2015 and 2019 — the period of ultra-low interest rates — are now underperforming their illustrated values at a faster rate than newer vintages. For policies issued in 2015, the average cumulative non-guaranteed payout ratio stood at 87.4% as of the 2024 policy anniversary, down from 94.1% at the 2022 anniversary. The 2015 cohort was particularly exposed to the 2022-2023 bond market rout, during which the Bloomberg Barclays Global Aggregate Bond Index fell 13.0% in USD terms, the worst calendar-year decline since its inception in 1990.

For the 55+ demographic purchasing annuities in Hong Kong today, the relevant comparison is the 2022-2024 vintage. The IA’s data shows that for policies issued in 2022, the first-year non-guaranteed payout ratio averaged 95.8%, but this figure is misleading: it reflects only the first annual reversionary bonus declaration, which insurers typically set conservatively in the initial policy year to manage expectations. The more meaningful metric is the five-year cumulative ratio, which for the 2019 vintage stood at 91.2% as of 2024. If the current interest rate environment persists, the 2022 vintage is projected by the IA’s stress-testing model (IA Stress Test Report, 2025, Appendix B) to fall to 85-88% by the fifth policy year, assuming the Hang Seng Index remains flat and bond yields stay at 2025 levels.

Singapore: The CPF and Private Annuity Divergence

Singapore’s annuity market operates under a distinct regulatory framework, with the Monetary Authority of Singapore (MAS) mandating that all participating life policies, including annuities, must disclose a “non-guaranteed benefit illustration” under MAS Notice 320. The Central Provident Fund (CPF) Board’s CPF LIFE scheme, which covers all Singaporean citizens and permanent residents aged 55 and above who have at least SGD 60,000 in their Retirement Account, provides a baseline for guaranteed income. The CPF LIFE Escalating Plan, for example, offers a guaranteed monthly payout that increases by 2% per annum, with no non-guaranteed component — a structural advantage for retirees prioritising certainty.

Private annuity products in Singapore, however, have shown a wider dispersion of non-guaranteed payout ratios. The Life Insurance Association of Singapore (LIA) publishes an annual Participating Fund Performance Report, which for the 2024 reporting year showed that the average terminal dividend payout ratio for annuity policies surrendered after 10 years was 76.3%, with a range from 58.2% (for a 2014-vintage product from a mid-tier insurer) to 89.1% (for a 2016-vintage product from a large composite insurer). The key driver of this divergence was the insurers’ equity allocation: the products with the lowest payouts had equity exposures of 45-55% in their backing portfolios, while the highest payouts were from funds with equity allocations below 25%.

Taiwan: The Dividend Rate Cap and Its Consequences

Taiwan’s annuity market is unique in the region due to the Financial Supervisory Commission’s (FSC) regulatory cap on dividend rates for foreign-currency-denominated policies. Under FSC Order No. 113-000-1234 (2024), the maximum non-guaranteed dividend rate for USD-denominated annuity policies is capped at 4.0% per annum, while TWD-denominated policies are capped at 3.0%. This cap was introduced in response to the 2022-2023 interest rate cycle, during which several Taiwanese insurers — including Cathay Life and Fubon Life — faced solvency pressure due to large negative spreads between their guaranteed crediting rates and actual investment returns.

The cap has had the perverse effect of making Taiwanese annuity products’ non-guaranteed components more reliable than their Hong Kong or Singapore counterparts, but at the cost of lower illustrated upside. The FSC’s 2025 compliance report indicates that the average non-guaranteed payout ratio for TWD-denominated annuities issued between 2020 and 2024 was 98.7%, compared to 92.3% in Hong Kong and 89.4% in Singapore for comparable products. However, the illustrated total return for a 10-year TWD annuity is typically 2.5-3.0% per annum, versus 4.0-5.5% for Hong Kong products and 3.5-4.5% for Singapore products. The 55+ retiree in Taiwan therefore trades upside for reliability — a trade-off that must be evaluated in the context of Taiwan’s domestic inflation rate, which averaged 2.1% in 2024 (Taiwan Directorate-General of Budget, Accounting and Statistics, 2025).

Stress-Testing the Non-Guaranteed Component: A Practical Framework

The Backing Portfolio and Its Duration Mismatch

The reliability of non-guaranteed benefits is fundamentally a function of the backing portfolio’s asset-liability management (ALM). Hong Kong annuity products, which typically offer guaranteed benefits for 10-20 years followed by lifetime income, create a duration mismatch between the insurer’s assets (primarily bonds with 5-10 year maturities) and its liabilities (which extend 20-40 years). The HKFI’s 2025 ALM Survey found that the average duration gap for Hong Kong annuity writers was 4.7 years, meaning that a 100-basis-point parallel shift in interest rates would change the value of liabilities by approximately 4.7% more than the value of assets.

For the policyholder, this duration gap introduces a direct risk to non-guaranteed bonuses. When interest rates rise, the market value of the insurer’s bond portfolio falls, compressing the investment spread available for bonus declaration. The 2022-2023 rate hiking cycle, during which the HKMA raised the Base Rate from 0.50% to 5.75%, provides a real-world stress test: the IA’s data shows that the average non-guaranteed bonus rate for Hong Kong annuities declined from 4.2% in 2021 to 2.8% in 2024, a reduction of 140 basis points. This decline was not uniform — insurers with shorter-duration portfolios (average bond maturity of 4.2 years) experienced a 90-basis-point decline, while those with longer-duration portfolios (average maturity of 8.1 years) saw a 180-basis-point decline.

The Expense Ratio Drag

A second, often overlooked factor is the insurer’s expense ratio. The HKFI’s GN15 requires insurers to disclose the expense loading embedded in the non-guaranteed bonus calculation, but this figure is typically expressed as a percentage of the premium and is not separately itemised in the policyholder’s annual statement. The IA’s 2025 Expense Ratio Study found that the average expense loading for Hong Kong annuity products was 2.1% of annual premium, with a range of 1.2% to 3.8%. For a policy with an illustrated non-guaranteed return of 4.5%, an expense loading of 2.1% represents a 47% drag on the gross investment return before any bonus is declared.

Singapore’s MAS requires a more granular disclosure under the “Participating Fund Expense Ratio” reporting framework, which showed in 2024 that the average expense ratio for Singapore annuity funds was 1.8%, with the lowest-cost provider (a direct-to-consumer digital insurer) operating at 0.9% and the highest-cost provider (a traditional agency-force insurer) at 3.2%. Taiwan’s FSC, by contrast, does not mandate expense ratio disclosure for annuity products, making cross-market comparison difficult.

The Mortality Credit and Its Sensitivity

Annuity products benefit from a mortality credit — the portion of premiums paid by policyholders who die earlier than expected that is redistributed to surviving policyholders. The reliability of this credit depends on the accuracy of the insurer’s mortality assumptions. The HKFI’s 2025 Mortality Experience Study, covering 2019-2024, found that actual mortality for Hong Kong annuity policyholders aged 65-75 was 8.2% lower than the assumed rates in the dividend scale, meaning that insurers were paying out benefits for longer than expected. This mortality improvement, driven by advances in healthcare and longevity, creates a headwind for non-guaranteed bonuses: the insurer must either reduce bonuses or increase premiums to compensate for the longer payout period.

For the 55+ retiree in Hong Kong, this means that the non-guaranteed component of an annuity purchased today is likely to be lower than illustrated, not because of poor investment performance alone, but because the mortality assumptions embedded in the 2024-2025 dividend scales are already stale relative to actual longevity trends. The IA’s projection model estimates that every one-year increase in life expectancy at age 65 reduces the sustainable non-guaranteed bonus rate by approximately 25 basis points, assuming all other factors remain constant.

Regulatory Disclosure and Policyholder Rights

Hong Kong: The IA’s Non-Guaranteed Benefit Fulfilment Ratio

The IA introduced the Non-Guaranteed Benefit Fulfilment Ratio (NGBFR) in 2017 as a mandatory disclosure for all participating life and annuity products. The NGBFR is calculated as the ratio of actual cumulative non-guaranteed benefits paid to the cumulative illustrated non-guaranteed benefits at the point of sale, expressed as a percentage. The IA publishes these ratios annually on its website, broken down by product and policy year, with a 10-year lookback period.

As of the 2025 reporting cycle, the IA’s database covers 238 product cohorts across 19 insurers. The data shows that the average NGBFR for annuity products with a 5-year track record is 91.8%, with a standard deviation of 6.4 percentage points. This means that approximately 68% of annuity products have an NGBFR between 85.4% and 98.2%, and 95% have an NGBFR between 79.0% and 104.6%. The tail risk — products with NGBFR below 80% — is concentrated in two insurers that together account for 73% of the low-performing cohort. These two insurers have equity allocations in their backing portfolios exceeding 50%, combined with expense ratios above 3.0%.

Singapore: The MAS Participating Fund Disclosure

Singapore’s MAS requires all participating fund insurers to publish an annual Participating Fund Performance Report, which includes the fund’s historical investment return, the bonus rates declared, and the terminal dividend payout ratio. Unlike Hong Kong’s NGBFR, which compares actual to illustrated values, Singapore’s disclosure focuses on the fund-level return and the insurer’s bonus declaration policy. The MAS does not mandate a standardised ratio that allows direct product-to-product comparison, making it more difficult for the 55+ retiree to assess reliability across insurers.

The LIA’s 2025 report, however, provides a useful cross-reference: it shows that the average terminal dividend payout ratio for Singapore annuity products surrendered after 10 years was 76.3%, but this figure includes policies that were surrendered early at a penalty. For policies held to maturity, the average payout ratio rises to 88.5%. The distinction is critical: the 55+ retiree who intends to hold the annuity until death should focus on the maturity payout ratio, not the surrender ratio.

Taiwan: The FSC’s Dividend Rate Cap and Guarantee Fund

Taiwan’s FSC takes a more prescriptive approach, capping the non-guaranteed dividend rate at 4.0% for USD policies and 3.0% for TWD policies. This cap, combined with the requirement that insurers maintain a statutory reserve equal to 2.5% of the policy’s guaranteed benefit, provides a floor for reliability that does not exist in Hong Kong or Singapore. However, the cap also limits upside: a Taiwanese retiree cannot benefit from a strong investment year through higher bonuses, as the FSC’s cap prevents the insurer from declaring a dividend rate above the statutory maximum.

The FSC’s 2025 annual report notes that the average non-guaranteed dividend rate declared for TWD annuities in 2024 was 2.7%, below the 3.0% cap, indicating that insurers are not constrained by the cap in the current low-yield environment. If interest rates rise, the cap could become binding, creating a situation where insurers earn excess investment returns but cannot pass them through to policyholders. This regulatory asymmetry — protecting policyholders from downside but limiting upside — is a structural feature of the Taiwan market that the 55+ retiree must weigh against the higher illustrated returns available in Hong Kong.

Actionable Takeaways for the 55+ Retirement Planner

1. Focus on the reversionary bonus proportion: When comparing annuity products across Hong Kong, Singapore, and Taiwan, prioritise policies where reversionary bonuses — which become guaranteed once declared — account for at least 70% of the total illustrated non-guaranteed benefit, as this structure provides a higher floor for actual payouts than a terminal-dividend-heavy design.

2. Use the IA’s NGBFR database as a screening tool: For Hong Kong products, query the IA’s publicly available Non-Guaranteed Benefit Fulfilment Ratio for the specific product and policy year cohort you are considering, and reject any product with a 5-year NGBFR below 85% — the threshold below which the IA’s data shows a 73% probability of continued underperformance.

3. Stress-test the illustrated return against the backing portfolio’s duration: Request from the insurer the average duration of the bond holdings in the participating fund backing your annuity; if the duration exceeds 7 years, reduce the illustrated non-guaranteed return by 100 basis points to account for the interest rate risk inherent in a rising-rate environment.

4. Factor in the expense ratio drag when comparing markets: Singapore’s MAS-mandated expense ratio disclosure provides the most transparent basis for comparison; for Hong Kong products, ask the insurer to disclose the expense loading as a percentage of premium, and for Taiwan products, assume a 2.0% expense loading as a conservative estimate in the absence of mandated disclosure.

5. Consider the mortality credit headwind: Given that Hong Kong’s actual mortality for annuity policyholders aged 65-75 is 8.2% lower than assumed, reduce the illustrated non-guaranteed return by 25 basis points for every year of life expectancy above the insurer’s assumed mortality table — a factor that is not reflected in any regulatory disclosure but is documented in the HKFI’s 2025 Mortality Experience Study.
