A company’s reported earnings increased from Rs 60 crore to Rs 85 crore. Management presents the Rs 25 crore improvement as evidence of operating progress.
But how much of the Rs 25 crore was operational, and how much was accounting?
The Earnings Bridge decomposes the movement from one period’s earnings to the next into its component sources: volume, price, cost, mix, currency, accounting changes, one-off items and below-the-line movements. The decomposition reveals whether the improvement came from operational actions (which management controls and which are likely to persist) or from accounting movements (which may reverse in subsequent periods).
The Bridge Structure
Period 1 reported earnings: Rs 60 crore
(+) Volume effect: Rs 8 crore (more units sold at existing margins)
(+) Price effect: Rs 6 crore (higher average selling prices)
(-) Input cost effect: Rs (4) crore (higher raw material costs)
(+) Operating efficiency: Rs 3 crore (lower waste, higher productivity)
(+) Mix effect: Rs 2 crore (shift toward higher-margin products)
(-) Currency effect: Rs (1) crore (adverse translation on exports)
(+) Depreciation reduction: Rs 4 crore (useful life extension)
(+) Provision release: Rs 5 crore (reversal of prior-year provision)
(+) Other non-recurring: Rs 2 crore (insurance recovery)
Period 2 reported earnings: Rs 85 crore
The reported improvement is Rs 25 crore. The operational improvement (volume + price + efficiency + mix, net of input cost and currency) is Rs 14 crore. The accounting and non-recurring improvement (depreciation change + provision release + insurance) is Rs 11 crore.
Nearly half of the reported improvement came from sources that are either non-recurring or accounting-driven. The operating improvement, which is the only portion that is likely to persist and compound, is Rs 14 crore.
The Governance Value
The Earnings Bridge converts a single reported number into an analytical decomposition that the board can govern. Instead of asking “did earnings improve?”, the board asks “what drove the improvement, and is the driver sustainable?”
A Rs 25 crore improvement driven by volume and pricing is sustainable and worth celebrating. A Rs 25 crore improvement driven by provision releases and depreciation changes is accounting movement that will not repeat and should not be rewarded.
In Northrop Management Private Limited’s financial advisory and governance work, the Earnings Bridge is a standard component of every board pack recommendation. It provides the board with the decomposition required to distinguish between operational progress and accounting presentation.
Ashish Chaudhary, frames the analytical principle directly: “Every earnings number should have an economic bridge behind it. The bridge separates what management did (operational improvement) from what the accounts did (accounting movement). The board should reward the first and investigate the second.”
Closing Implication
Reported earnings are a single number. The Earnings Bridge reveals what that number is made of. A board that receives the bridge at every reporting period governs with the decomposition required to distinguish between genuine improvement and accounting presentation. A board that receives only the number governs with a conclusion whose composition it has not examined.
