Employee Benefits (Gratuity & Defined Benefit Plans)
Why a company can owe an employee who hasn't resigned yet, and won't for years, a real liability on its balance sheet today — calculated using life-expectancy tables and interest-rate assumptions, not a simple formula.
In plain English
In India, the Payment of Gratuity Act, 1972 requires most employers to pay a lump sum to an employee who leaves after 5 or more years of continuous service — roughly 15 days' salary for every completed year of service. This sounds like a simple payment made when someone finally resigns or retires. But accounting doesn't wait for that day: from the moment an employee joins and starts building up years of service, the company is quietly accumulating a genuine obligation to pay them, someday, an amount that depends on things nobody can know for certain today — how long the employee will stay, what their final salary will be, how long they might live. Employee benefit accounting estimates and recognises that slow-building obligation years before the actual cheque is ever written.
Words you'll need first
A retirement or long-service benefit (like gratuity) where the employer promises a specific, formula-based payout regardless of how any underlying investments perform. The RISK sits entirely with the employer — if fund investments perform poorly, or employees live longer or earn more than expected, the company still owes the full promised amount. This differs from a Defined CONTRIBUTION plan (like most Provident Fund arrangements), where the employer's only obligation is a fixed contribution each period — the eventual payout depends on how that money grows, and the employee bears that investment risk.
A specialist calculation, done by a qualified actuary, that estimates the present value of a company's total defined benefit obligation using assumptions about future salary growth, attrition, mortality, and a discount rate to bring future payouts back to today's rupees — similar in spirit to how a Lease Liability discounts future rent payments. Because these assumptions shift year to year, the estimated liability moves too, even if not a single employee's actual circumstances changed.
A worked example, with numbers
| Movement in the obligation | ₹ crore |
|---|---|
| Opening defined benefit obligation | 80 |
| + Current service cost (P&L expense) | 10 |
| + Interest cost (P&L expense) | 6 |
| + Actuarial loss (via Other Comprehensive Income, not P&L) | 4 |
| − Benefits paid out (cash) | (8) |
| Closing defined benefit obligation | 92 |
- The gratuity liability grows from ₹80 crore to ₹92 crore over the year, even though the company actually paid out only ₹8 crore in cash — most of the movement is non-cash accounting, not cash leaving the business.
- Current service cost (₹10 crore) and interest cost (₹6 crore) — ₹16 crore combined — hit the P&L as expenses, reducing reported operating profit, without a single rupee being paid to any employee that year.
- The ₹4 crore actuarial loss, caused purely by a change in assumptions, does NOT go through the P&L at all — it's routed through Other Comprehensive Income (OCI), adjusting equity directly without touching reported net profit. This is deliberate: assumption-driven swings shouldn't make core operating profit look volatile.
- Because this liability depends on assumptions, it moves every year even for a company whose actual workforce and pay practices haven't changed at all.
What it does to the financial statements
Impact on the P&L
- Current service cost and interest cost on the defined benefit obligation are recognised as P&L expenses every year, usually within employee benefit expenses — a real, ongoing cost of employing people, even between actual payout events.
- Actuarial gains and losses — swings from REVISING assumptions rather than new service being earned — are excluded from the P&L and routed through Other Comprehensive Income, keeping reported net profit from swinging around purely due to assumption changes.
- A company with a young, fast-growing workforce typically has a smaller, faster-growing gratuity obligation; a company with a large, long-tenured workforce nearing retirement faces a much bigger, more mature obligation and higher annual costs.
- Companies that 'fund' their gratuity obligation via a separate trust see the expected return on those fund assets partially offset the interest cost in the P&L — so the net charge depends on both the obligation AND the funding vehicle's expected performance.
Impact on the Balance Sheet
- The NET liability on the balance sheet is the defined benefit obligation MINUS the fair value of any plan assets set aside to fund it — a fully funded company may show little or no net liability, while an unfunded company shows the full obligation.
- Actuarial gains and losses accumulate directly in equity through Other Comprehensive Income rather than through retained earnings via the P&L — shareholders' equity can move for reasons that never show up as reported profit or loss.
- A rising interest-rate environment generally REDUCES the present value of a defined benefit obligation, which, all else equal, can shrink the liability — the opposite of the intuition that higher rates are generally bad news for a balance sheet.
- For companies with very large, long-tenured workforces, the defined benefit obligation can be a genuinely material balance sheet liability worth checking, not just a footnote curiosity.
Which standard covers this
In India this is governed by Ind AS 19 – Employee Benefits, notified under the Companies (Indian Accounting Standards) Rules and applicable to companies that follow Ind AS, working alongside the statutory entitlement rules in the Payment of Gratuity Act, 1972 and other relevant labour law.
How it's recognised globally
Globally, the equivalent is IAS 19 – Employee Benefits, and the defined benefit vs defined contribution distinction, the actuarial valuation approach, and the OCI treatment for actuarial gains and losses work essentially the same way worldwide. Under US GAAP (ASC 715), the same core concepts apply, though defined benefit pension plans (historically far more common and larger in scale in the US than India's gratuity obligations) have differing technical mechanics around how actuarial gains and losses are eventually recognised in profit or loss over time — a process IFRS/Ind AS largely does away with by routing them permanently through OCI. Broadly, both frameworks share the same underlying philosophy: separate the predictable, service-driven cost (which hits the P&L) from the unpredictable, assumption-driven swings (which don't).
Real example — Indian listed company
Large employee-base companies are where this concept becomes genuinely material, and India's big IT services firms are a natural example given how many hundreds of thousands of employees they carry. A company like TCS, with a workforce well into six figures, accrues meaningful current service cost and interest cost on its gratuity obligation every year, purely as a function of headcount, tenure and salary growth, independent of how many employees actually resign or retire that particular year. For such companies, actuarial assumptions — the discount rate (typically linked to Indian government bond yields), assumed salary escalation, and expected attrition — are disclosed in the notes, and shifts in these assumptions from year to year can move the reported defined benefit obligation by meaningful amounts even when the company's HR policies and actual workforce trends haven't changed at all. This is a useful, concrete reminder that a large chunk of what appears in 'employee benefit expenses' for a labour-intensive company is genuinely actuarial and forward-looking, not simply a tally of salaries actually paid that year.
