💡 Accountant's Note

Under IFRS 15.56, highly variable success fees are constrained until the uncertainty is resolved. Upon deal close (the triggering event), the constraint is lifted and the full fee is recognized immediately. No revenue was recognized during the advisory process.

Practitioner & Systems Framework

💻 ERP Architecture

The success fee must remain in the contract liability or as a zero-revenue constrained item throughout the advisory period. No partial revenue recognition is appropriate during the transaction process — even if the deal is 'highly likely,' the binary nature of deal completion means the fee remains fully constrained until actual completion. The triggering event (deal closing, signing of final transaction documents, receipt of regulatory approval — as defined in the engagement letter) is the recognition date. At that date, raise the invoice immediately and recognize the full fee. For M&A mandates where the fee is a percentage of deal value, the fee is calculated on actual deal value at close, not an estimated value.

⚠️ Audit Flags

(1) Triggering event documentation — what exactly constitutes deal 'close' under the engagement letter? Exchange of contracts, unconditional completion, receipt of merger clearance? Auditors verify that the recognition date matches the contractual trigger. (2) Deal value calculation — for percentage-based success fees, confirm the fee is calculated on the correct base (enterprise value, equity value, upfront cash vs. including deferred consideration). (3) Partially contingent fees — if the engagement letter includes a non-contingent retainer component plus a contingent success component, the retainer portion is recognized over time while the success portion remains constrained. Ensure the split is correctly modelled.

📄 Required Documentation

Engagement letter (fee structure, triggering event definition, fee calculation methodology), deal completion documents (signed purchase agreement, completion notices, regulatory clearance), fee calculation worksheet, invoice, and IAS 12 deferred tax assessment on fee income.
