Testing contingent consideration in a business combination means testing three things separately: the acquisition-date fair value of the obligation to transfer additional consideration if specified future events occur, its classification as a financial liability or as equity, and — for a liability — its remeasurement at every subsequent reporting date through profit or loss until settlement. This procedure focuses on the contingent element itself, which is tested against the acquired business's own post-acquisition performance, separately from the rest of the purchase price allocation.
Why this needs its own working paper
The purchase price allocation working paper spreads the whole consideration across the identifiable assets and liabilities acquired and goodwill. The contingent consideration element has a life of its own after that: it depends on an earnings target, a revenue target, or a regulatory milestone being reached in the acquired business, and the auditor needs evidence from that business's actual post-acquisition results, not just from the acquisition agreement.
The testing sequence
- 01Obtain the full earn-out mechanism from the purchase agreementThe specific metric, the measurement period, the payout formula or schedule, any cap or floor, and whether payment is in cash, shares, or a mix.
- 02Test the classification of the obligation as a liability or equityA fixed number of the acquirer's own shares settled only on a fixed metric is one of the few paths to equity classification; almost everything else, including a variable number of shares or any cash-settled element, is a liability.
- 03Recompute the acquisition-date fair value independentlyThis requires its own valuation — typically a probability-weighted scenario model or an option-pricing approach where the payoff is non-linear — and should not be accepted as the number in the sale and purchase agreement, which is a negotiated cap, not a fair value.
- 04Confirm the amount is included in the consideration transferred, not expensedGenuine contingent consideration for the business acquired sits in consideration transferred and affects goodwill; amounts contingent on the continued employment of selling shareholders are compensation for post-combination services and are expensed as incurred — this distinction is tested on the substance of the arrangement, not its label.
- 05Obtain the acquired business's actual results against the earn-out metric for the period under auditAgree the metric computation to the general ledger of the acquired business using the definition in the agreement, which frequently differs from statutory profit — add-backs, specific exclusions and a defined EBITDA are common.
- 06Recompute the remeasurement of a liability-classified obligation at the reporting dateChanges in fair value driven by changes in the probability or timing of the target being met go through profit or loss, not through goodwill — goodwill is only adjusted for measurement-period adjustments to information existing at the acquisition date, within twelve months of it.
- 07Test whether the measurement period has closedAdjustments made more than twelve months after the acquisition date, or made for events that occurred after it rather than facts that existed at it, cannot adjust goodwill and must be recognised in profit or loss.
| Question | Evidence |
|---|---|
| Liability or equity | Settlement mechanism — fixed shares on a fixed metric versus variable shares, cash, or any linkage to continued employment |
| Acquisition-date fair value | Independent probability-weighted or option-pricing valuation, not the contractual cap |
| Is it consideration or compensation | Substance of the linkage — tied to the business's performance versus tied to a seller staying employed |
| Remeasurement this year | Acquired business's actual results against the metric, recomputed fair value, routed through profit or loss |
A contingent consideration liability remeasured down because the acquired business underperformed is sometimes treated internally as good news and left untested. The remeasurement itself, and the reasons behind the shortfall, often point straight at the same impairment indicators relevant to the goodwill recognised on the same acquisition.
How we think about this
Agreeing the earn-out metric to the acquired business's actual results is a mechanical reconciliation. Valuing the contingent obligation, at acquisition and at every remeasurement date after, is a judgement about probabilities and timing that depends on understanding the acquired business, and that judgement belongs to the auditor, not to a template.
