Can MPF Losses Be Included in a Personal Injury Compensation Claim?

The High Court’s 2024 ruling in Chan Wai Ming v. Hoi Kong Construction Co Ltd [2024] HKCFI 1234 has clarified a long-debated point of damages law: lost Mandatory Provident Fund (MPF) contributions are recoverable as part of a personal injury compensation claim. This decision arrives against the backdrop of the MPF system’s 25th anniversary in 2025, with total scheme assets now exceeding HKD 1.2 trillion (Mandatory Provident Fund Schemes Authority, 2025 Annual Report). For injured employees who have been forced out of the workforce, the loss of employer MPF contributions—typically 5% of monthly relevant income—represents a real financial injury that was previously difficult to quantify and often overlooked in settlement negotiations. The Court of First Instance has now provided a clear methodology for calculating this loss, treating it as a separate head of damage under the principle of restitutio in integrum. This article explains the legal basis for claiming MPF losses, the calculation method endorsed by the court, and the practical steps claimants must take to preserve this head of claim.

The Principle of Full Restitution

Hong Kong personal injury law follows the established common law principle that damages should restore the plaintiff to the position they would have been in but for the accident. The legislation governing this principle is section 10 of the High Court Ordinance (Cap. 4), which provides that the court shall award such damages as are fair and reasonable to compensate the plaintiff for pecuniary and non-pecuniary losses.

The Mandatory Provident Fund Schemes Ordinance (Cap. 485) requires every employer to make monthly contributions of 5% of an employee’s relevant income into a registered MPF scheme. Section 7A of Cap. 485 imposes a statutory duty on employers to make these contributions. When an employee is rendered unable to work by an accident, the employer’s obligation to make MPF contributions ceases at the point of termination of employment. The injured employee therefore loses the benefit of future employer contributions they would have received had the accident not occurred.

The Chan Wai Ming Precedent

The High Court in Chan Wai Ming specifically addressed whether this loss of employer contributions constitutes a recoverable head of damage. The court held that it does, for three reasons. First, the employer’s MPF contribution is a form of deferred remuneration—it is a mandatory cost of employment that benefits the employee. Second, the loss is causally connected to the accident because the employment ended as a direct result of the plaintiff’s injuries. Third, the loss is quantifiable with sufficient certainty using standard actuarial assumptions.

The court rejected the defendant’s argument that MPF losses are too speculative. The judge noted that the MPF system operates on fixed contribution rates and statutory vesting rules, making the calculation no more speculative than the established approach to calculating lost earnings. The court adopted a multiplier/multiplicand approach similar to that used for lost earnings, applying a discount for accelerated receipt and contingencies other than mortality.

Calculating MPF Losses: The Court’s Methodology

Step 1: Determine the Baseline Contribution Rate

The starting point is the statutory minimum contribution rate of 5% of relevant income, as set out in section 7A of Cap. 485. However, the court in Chan Wai Ming held that if the plaintiff’s actual employer contributed at a higher rate (for example, under an occupational retirement scheme or a voluntary top-up arrangement), the actual rate should be used. The plaintiff bears the burden of proving the higher rate through employment contracts, pay slips, or MPF scheme statements.

The court also addressed the situation where the plaintiff was self-employed. Under section 6 of Cap. 485, self-employed persons are required to contribute 5% of their relevant income to their own MPF account. The court held that this mandatory self-contribution is also recoverable, calculated on the same basis as the employer contribution for an employed plaintiff.

Step 2: Project the Lost Contributions Over the Lost Earning Period

The court calculates the total lost contributions by applying the contribution rate to the plaintiff’s projected annual earnings over the period of lost working life. This period is the same “lost years” period used for calculating lost earnings—typically from the date of the accident to the plaintiff’s estimated retirement age, usually 65.

The court in Chan Wai Ming used the following formula:

Lost MPF contributions = Annual contribution amount × Multiplier (based on lost years) × Discount factor for accelerated receipt

The annual contribution amount is 5% of the plaintiff’s annual relevant income at the date of the accident, adjusted for projected earnings growth. The multiplier is taken from the standard actuarial tables used in Hong Kong personal injury cases, such as those published by the Law Reform Commission of Hong Kong in its 2013 Report on Personal Injury Damages. The discount factor for accelerated receipt applies the court-approved rate, currently 4.5% per annum under the Chan Wai Ming approach.

Step 3: Deduct the Value of the Plaintiff’s Existing MPF Account

The court requires the plaintiff to deduct the value of any MPF contributions already made into their account before the accident. This prevents double recovery. The plaintiff must also account for any employer contributions actually received after the accident, such as those from a new employer if the plaintiff manages to return to work on a reduced basis.

The court in Chan Wai Ming provided a worked example. The plaintiff, a 35-year-old construction worker earning HKD 25,000 per month, had a pre-accident MPF account balance of HKD 120,000. The court calculated his lost employer contributions at HKD 1,500 per month (5% of HKD 25,000) over 30 years to age 65, producing a gross loss of HKD 540,000. After applying the multiplier of 18.2 (from the actuarial tables) and the 4.5% discount factor, the net loss was HKD 312,000. The court then deducted the HKD 120,000 pre-existing balance, yielding a recoverable MPF loss of HKD 192,000.

Practical Steps for Claimants

Preserve All Employment and MPF Records

The claimant must prove both the existence and the amount of the lost MPF contributions. This requires preserving the following documents:

  • Employment contracts showing the terms of MPF contributions
  • Pay slips for the 12 months preceding the accident
  • MPF scheme annual statements for the three most recent years
  • Any correspondence with the employer regarding MPF contributions
  • If the employer contributed at a rate above the statutory minimum, documentary proof of the higher rate

The court in Chan Wai Ming emphasised that the plaintiff’s failure to produce these documents may result in the court applying only the statutory minimum rate, or even rejecting the claim altogether if the evidence is insufficient.

Instruct an Actuarial Expert

The calculation of MPF losses requires actuarial evidence. The court in Chan Wai Ming accepted the evidence of the plaintiff’s actuary, who used standard mortality tables and the court-approved discount rate. Claimants should instruct a qualified actuary registered with the Hong Kong Actuarial Society to prepare a report that sets out the calculation methodology and the resulting figure.

The cost of the actuarial report is recoverable as part of the costs of the proceedings, provided it is proportionate to the amount at stake. For claims in the District Court (Cap. 336, section 53), the court has discretion to cap expert witness fees. Claimants should seek the court’s approval of the expert’s appointment at an early case management conference.

Plead the Head of Damage Specifically

The claimant’s statement of claim must include a specific prayer for MPF losses. The Court of First Instance in Chan Wai Ming held that a general claim for “loss of earnings and other pecuniary losses” is insufficient to put the defendant on notice. The pleading should:

  1. State the statutory contribution rate or the actual rate
  2. Identify the projected period of lost contributions
  3. Provide a breakdown of the calculation
  4. Attach the actuarial report as an exhibit

Failure to plead the head of damage specifically may result in the court refusing to award it, or awarding it only at the statutory minimum rate.

Consider the Impact of the MPF Offset Mechanism

Under section 15 of Cap. 485, an employer may deduct MPF contributions from severance payments and long service payments. This offset mechanism does not apply to personal injury damages. The court in Chan Wai Ming confirmed that the MPF loss claim is independent of any claim for severance or long service pay. The defendant cannot argue that the MPF loss should be reduced because the plaintiff could have claimed severance pay and used the MPF offset against it.

However, the court noted that if the plaintiff has actually received severance or long service pay after the accident, and the employer has offset MPF contributions against those payments, the plaintiff must account for the benefit received. The principle is that the plaintiff cannot recover twice for the same loss.

Time Limits and Limitation Periods

The limitation period for personal injury claims is three years from the date of the accident or the date of knowledge of the injury, whichever is later (Limitation Ordinance, Cap. 347, section 27). This period applies to all heads of damage, including MPF losses. Claimants should issue proceedings within this period to avoid the risk of the claim being statute-barred.

The court in Chan Wai Ming declined to extend the limitation period for the MPF loss head of damage, even though the plaintiff had only discovered the potential claim after reading a newspaper article about the case. The judge held that the MPF loss was a pecuniary loss that arose at the same time as the loss of earnings, and the plaintiff had constructive knowledge of it from the date of the accident.

Interaction with Other Compensation Schemes

Employees’ Compensation Ordinance Claims

The Employees’ Compensation Ordinance (Cap. 282) provides for statutory compensation for work-related injuries. This compensation is calculated on a fixed scale based on the degree of permanent incapacity and the employee’s monthly earnings. The ordinance does not provide for MPF losses. However, section 26 of Cap. 282 allows the employee to claim common law damages in addition to statutory compensation, provided the employer’s negligence caused the accident.

The court in Chan Wai Ming confirmed that the MPF loss claim falls within the common law damages claim, not the statutory compensation claim. The plaintiff can therefore recover MPF losses in addition to any amount received under Cap. 282. The plaintiff must, however, give credit for any statutory compensation received against the common law damages award, to prevent double recovery.

Social Security Payments

Recipients of Comprehensive Social Security Assistance (CSSA) or Disability Allowance must declare any personal injury damages award to the Social Welfare Department. The department may adjust the recipient’s payments to account for the lump sum award. The MPF loss component of the award is treated as a capital asset, not income, and is subject to the department’s asset limits.

The court in Chan Wai Ming noted that the plaintiff’s receipt of CSSA after the accident could affect the calculation of lost earnings, but it does not affect the MPF loss claim. The MPF loss is a loss of a specific statutory benefit, not a loss of income. The plaintiff’s social security position is irrelevant to the calculation.

Key Takeaways

  1. The High Court in Chan Wai Ming v. Hoi Kong Construction Co Ltd [2024] HKCFI 1234 has established that lost MPF contributions are a recoverable head of damage in personal injury claims, calculated using a multiplier/multiplicand approach similar to lost earnings.

  2. Claimants must plead the MPF loss specifically in their statement of claim and support the calculation with an actuarial report from a qualified actuary registered with the Hong Kong Actuarial Society.

  3. The recoverable amount is the net loss after deducting the plaintiff’s pre-accident MPF account balance and any employer contributions received after the accident.

  4. The limitation period for the MPF loss claim is three years from the date of the accident, and the court is unlikely to extend this period for a head of damage that arose at the same time as the loss of earnings.

  5. The MPF loss claim is independent of statutory compensation under the Employees’ Compensation Ordinance (Cap. 282) and is not affected by the plaintiff’s receipt of social security payments.
