One definition of EBITDA: making MIS and audited measures agree

Short answer: When the board pack and the earnings release show different EBITDA, the cause is almost never the systems. It is that nobody wrote the definition down, so two teams made different choices about other income, exceptional items, lease costs and cost allocation. Fix it by writing one arithmetic rule over the ledger, naming every variant, and keeping the bridge visible.

Where the two numbers come from

EBITDA is not defined by any accounting standard. That is the whole problem. It is an arithmetic rule someone chose, and Indian companies choose differently in at least five places:

• Other income. In, out, or in only for the operating part of it. This single choice moves the number more than any other.
• Exceptional and one-off items. Restructuring, impairment, a legal settlement, a gain on sale. Excluded from the management view, usually present in the statutory subtotal.
• Lease costs. After Ind AS 116, rent that used to be an operating expense is depreciation and interest. An EBITDA computed after that change is not comparable with one computed before it, and some management packs still add rent back to stay comparable with history.
• Share-based payment. Non-cash, so frequently excluded from the management measure and never from the statutory one.
• Allocated corporate costs. A business unit EBITDA after allocation and the group EBITDA before it are different measures that carry the same name.

Add the share of profit from joint ventures, foreign exchange movement and government incentives, and there are enough choices to produce a dozen defensible numbers from one trial balance.

Why this is getting more expensive to leave alone

Ind AS 118, the Indian equivalent of IFRS 18, introduces disclosure requirements for management-defined performance measures: subtotals of income and expenses used in public communication outside the financial statements to convey management’s view of performance. Those measures have to be defined, reconciled to the closest subtotal required by the standards, and shown with the tax and non-controlling interest effect of each adjustment, in one note in the audited financial statements. NFRA recommended the standard in December 2025 for periods beginning on or after 1 April 2027; it becomes law when the MCA notifies it. The detail is in your adjusted EBITDA is about to be audited.

Nothing in that changes what FP&A may measure internally. It changes the cost of publishing a number you cannot derive twice the same way. If the management measure and the published measure are the same number, the note is a by-product. If they differ and nobody knows why, the reconciliation becomes a year-end project.

Write the definition as arithmetic, not as prose

A definition that lives in a footnote of a slide is not a definition. Write it as a rule that a machine can execute over the mapped ledger:

1. Start from a named base. Pick one starting subtotal and state it, for example revenue from operations less cost of materials, employee benefits and other expenses, before depreciation, amortisation, finance cost and tax.
2. List each adjustment as a named line, with its sign and its source. “Add back: share-based payment (ledger group SBP)”. Not “adjusted for non-cash items”.
3. State what is excluded and why. Other income out, except interest on customer receivables, because that is trade-related.
4. Say at what level it holds. Group, entity, business unit, product. A measure that only means something after allocation is not the same measure as one before it.
5. Version it. When the rule changes, the old one keeps its number and the pack shows both for one period.

Two or three variants are fine. What is not fine is three variants with one name.

Then hold the bridge

The bridge is a short table that gets rebuilt every month, not once a year: the management measure, each adjustment, and the statutory subtotal it lands on. Three properties make it survive:

• Every line is a computation over ledger balances, not a typed number. If an adjustment cannot be expressed as a rule over mapped accounts, it is a judgement, and judgements belong in a controlled input with an owner and a date, not in an unexplained cell.
• Every figure traces to the journal entry it came from. The first question on any adjustment is “what is in it”, and the only good answer is a list of entries.
• The bridge is produced for every period, including the ones nobody asked about. A reconciliation that exists only for the quarters that were queried is not a control.

What FP&A can do this quarter

1. Collect every EBITDA number the company has published or circulated in the last four quarters, from decks, releases, lender reporting and the board pack.
2. Write the arithmetic rule for each one and see how many rules you actually have.
3. Pick the base. Usually the one closest to the statutory subtotal, because it is the one that will need a reconciliation.
4. Express the others as named adjustments to the base.
5. Build the bridge for the last four quarters and check it ties every time.
6. Agree the wording with whoever signs the investor communication, and with the auditors if the measure is published.

Where FINK fits

FINK is MIS. It does not prepare your statutory financial statements or their notes — FINAHQ does that, from the same entity. What FINK does hold is the management view of the same mapped data: an MIS chart of accounts that is yours and separate from the statutory chart but mapped to it, bespoke reporting groups so the ledgers can be grouped the way the business is run, and a KPI store where a measure is defined once and refreshes when the ERP syncs. Figures are computed arithmetically from the ERP data rather than predicted, and every figure links back to the journal entry it came from, which is what makes a bridge checkable rather than assertable.

Because the MIS chart is mapped to the statutory one, the management measure and the statutory subtotal are two groupings of the same entries, so the difference between them is a list of adjustments you can name. The segment version of the same discipline is in segment reporting and management MIS from the same numbers, and the budgeting version is in budget versus actuals when the profit and loss layout changes.
