Module 43 — Pension & Employee Benefits Finance
Defined benefit vs defined contribution pension structures, IAS 19 actuarial assumptions and their P&L sensitivity, pension deficit management, EOBI obligations in Pakistan, and gratuity fund design.
Learning Objectives
- Distinguish defined benefit from defined contribution obligations and their balance sheet impact
- Apply IAS 19 to calculate pension expense, net liability, and OCI movements
- Manage actuarial assumptions: discount rate, salary growth, mortality — and their P&L sensitivity
- Structure a compliant gratuity fund for a Pakistani employer
- Navigate EOBI (Employees' Old Age Benefits Institution) obligations
1. Employee Benefits Classification (IAS 19)
The Four Categories
| Category | Examples | Accounting |
|---|---|---|
| Short-term benefits | Salaries, bonuses, paid leave | Accrue as service is rendered |
| Post-employment benefits | Pension, gratuity, post-retirement medical | DB or DC accounting (see below) |
| Other long-term benefits | Long-service leave, deferred compensation | Actuarial methods but OCI recycled to P&L |
| Termination benefits | Redundancy, early retirement packages | Recognize at earlier of: offer made or redundancy plan announced |
Defined Contribution vs Defined Benefit — The Core Distinction
Defined Contribution (DC):
- Employer commits to contribute a fixed amount to a fund
- Investment risk falls on the employee — what the fund grows to determines retirement benefit
- Accounting: simple — contribution = expense when due
- No balance sheet liability beyond accrued unpaid contributions
Defined Benefit (DB):
- Employer commits to pay a specified retirement benefit (e.g., 2% × years of service × final salary)
- Investment risk falls on the employer — employer funds the shortfall if assets fall short of obligation
- Accounting: complex — actuarial calculation; DB liability on balance sheet
- Creates potentially large, volatile balance sheet obligation
2. Defined Contribution Plans in Pakistan
Pakistan Provident Fund
- Employer contribution: Typically 8.33% of basic salary per month (matches employee's 8.33%)
- Recognized Provident Fund (RPF): FBR-approved; employer contributions exempt from tax for employee
- Unrecognized PF: No FBR approval; contributions taxable; avoid for employee relations
- Investment: Trustee-managed; must follow FBR investment policy (specified allocation to government securities)
EOBI (Employees' Old Age Benefits Institution)
Mandatory social security program for workers in industrial establishments with 5+ employees:
- Employer contribution: 5% of minimum wage (currently approximately PKR 570/month per employee)
- Employee contribution: 1% of minimum wage
- Benefit: Retirement pension on reaching 60 (male) or 55 (female) with minimum 15 years contributions
- Non-compliance penalty: FIR (criminal case) under EOBI Act 1976
CFO action: Ensure EOBI registration for all employees above threshold. EOBI registration is audited by external auditors under Companies Act 2017.
PESSI / ESSI (Provincial Social Security Institutions)
Punjab ESSI, Sindh ESSI, KP ESSI — provincial health insurance programs:
- Contribution: approximately 6% of wages (employer: 5%, employee: 1%)
- Benefit: medical care for registered workers
- Registration mandatory for industrial/commercial establishments with 10+ employees
3. Defined Benefit Plans — IAS 19 Mechanics
The Net Defined Benefit Liability
Net DB Liability = Present Value of DB Obligation − Fair Value of Plan Assets
If plan assets exceed obligation → net DB asset (but recognition limited; surplus cap applies).
Components of DB Cost — Where They Go
| Component | P&L or OCI | Description |
|---|---|---|
| Current service cost | P&L | Cost of benefit earned by employees in current year |
| Past service cost | P&L (immediately) | Cost of benefit improvements — no more deferral under IAS 19 (2011) |
| Net interest on net liability | P&L | Net DB liability × discount rate |
| Actuarial gains and losses | OCI (not recycled) | Changes due to assumption changes or experience differences |
The Projected Unit Credit (PUC) Method
The actuarial method used to calculate the DB obligation:
- Each year of service earns a unit of benefit (e.g., 2% of final salary)
- Each unit is projected to the expected retirement date (using salary growth and promotion assumptions)
- The projected benefit is discounted back to the balance sheet date
PBO = Σ [Projected benefit per unit of service × Number of service years × Discount factor]
Key Actuarial Assumptions
| Assumption | Basis | Pakistan Guidance |
|---|---|---|
| Discount rate | High-quality corporate bond yields; or government bond yields where no deep corporate bond market | Pakistan: use GoP PIB yields; currently 13–15% (reflecting high interest rate environment) |
| Salary growth rate | Expected future salary increases | Pakistan: align with CPI + real wage growth; typically 10–14% in current environment |
| Mortality | Mortality tables reflecting workforce demographics | Pakistan: EFU 61-66 tables most commonly used |
| Employee turnover | Expected future attrition rates | Company-specific; typically 5–15% per year |
| Retirement age | Expected retirement age | 60 for male, 55 for female under Shops & Establishments regulations |
Sensitivity of DB Liability to Assumptions
| Assumption Change | Impact on Obligation |
|---|---|
| Discount rate +1% | Obligation decreases ~8–12% (for typical scheme) |
| Discount rate −1% | Obligation increases ~8–12% |
| Salary growth +1% | Obligation increases ~5–8% |
| Mortality improves 1 year | Obligation increases ~2–4% |
These sensitivities must be disclosed in the notes to financial statements under IAS 19.139.
4. Gratuity Fund (Pakistan)
Legal Basis
The payment of gratuity is governed by:
- West Pakistan Industrial and Commercial Employment (Standing Orders) Ordinance 1968
- Minimum one month's wages for each completed year of service, payable on retirement/resignation after 5+ years
Funding vs Unfunded Gratuity
- Unfunded: Company recognizes liability on balance sheet; pays from operating cash when due
- Funded (FBR-approved gratuity fund): Company sets up a separate trust; contributes annually to fund the obligation
CFO preference: Funded gratuity scheme, because:
- Tax deductible: contributions to FBR-approved fund are tax-deductible
- Funds assets grow (tax-exempt within the trust)
- Protects employees if company faces financial difficulty
Gratuity Fund Setup Requirements
- FBR approval: Apply to FBR for approval as a "recognized gratuity fund"
- Trust deed: Formal legal document establishing the trust and naming trustees
- Trustees: Minimum 3 trustees; must include employer and employee representatives
- Actuary: Annual actuarial valuation required for funded scheme
- Investment restrictions: FBR specifies maximum allocation to different asset classes
IAS 19 Treatment of Funded Gratuity
A funded gratuity scheme in Pakistan is typically a defined benefit plan (because the benefit formula is based on final salary and service):
- Actuarial valuation required annually
- DB liability = PV of obligation − fair value of fund assets
- Current service cost and net interest → P&L
- Actuarial gains/losses → OCI
5. Pension Deficit Management
Understanding the Actuarial Deficit
Actuarial deficit = PV of DB obligation − Fair Value of plan assets
Deficit increases when:
- Discount rate falls (obligation present value rises)
- Asset returns disappoint (plan assets fall in value)
- Actual salary growth exceeds assumption
- Employees live longer than assumed (mortality experience worse than table)
Deficit Recovery Plan
Options for addressing an actuarial deficit:
- Additional contributions: Make cash contributions to the fund above the regular current service cost
- Liability management: Buy out small pensions with lump sum payments (deferred liability elimination)
- Benefit restructuring: Change future benefit accrual for current employees (requires consultation)
- Asset strategy: Increase allocation to return-seeking assets vs bonds (increases risk)
- Liability-Driven Investment (LDI): Match asset duration to liability duration to reduce interest rate risk
Pakistan-Specific Deficit Challenge
In the high-interest-rate environment of 2022–2023:
- Discount rates rose sharply → DB obligations fell sharply
- This improved funding positions for companies with DB plans
- As rates normalize, discount rates will fall again → obligations will rise
- CFO action: model the obligation under various rate scenarios; plan contribution strategy accordingly
Self-Assessment
-
A company has a defined benefit gratuity scheme. The following data applies: present value of obligation PKR 280M, fair value of plan assets PKR 220M, current service cost PKR 25M, discount rate 13%, expected return on plan assets 11%. Calculate: (a) net DB liability, (b) current service cost charge, (c) net interest cost, (d) total DB expense in P&L.
-
The discount rate falls from 13% to 11% at year-end. If the sensitivity of the obligation to a 1% rate change is PKR 22M, calculate the approximate increase in the DB obligation and show how this is recognized (P&L or OCI? Explain why).
-
You are setting up a gratuity fund for a company with 200 employees, average salary PKR 150,000/month, average service 5 years. Outline the steps to establish an FBR-approved fund, the investment policy for the fund assets, and the annual reporting obligations.
