CFO’s Claim for $200,000 Performance Bonus Dismissed

Is an employee entitled to a performance bonus when, despite clear eligibility criteria for the bonus, the employee reinterprets the criteria because he believes he knows better than his employer?

In judgment of Ngai Nai Ping Jango v Banshing Industrial Co (Pte) Ltd [2026] SGDC 277, the District Court decided that there was no such entitlement. Accordingly, the court dismissed the claim brought by Mr Jango Ngai, the former Chief Financial Officer (CFO) of Banshing Group, for S$ 200,000 of performance bonus.

Background to the case

Mr Ngai’s employment contract stated that the eligibility criteria for a performance bonus would be “agreed and defined during probation period”. Mr Ngai and Banshing did not come to any agreement on the criteria during the probation period.

After the probation period, the management of Banshing informed Mr Ngai by email that the criteria for the bonus would be the delivery of an integrated financial valuation model, in the form of a Microsoft Excel workbook comprising seven worksheets following a mind map based on the book “Valuation: Measuring and Managing the Value of Companies, University Edition (John Wiley & Sons, 7th Ed, 2020)” by Tim Koller, Marc Goedhart & David Wessels. Mr Ngai acknowledged the criteria by return email on the same day. The court referred to this criteria as the “Seven Worksheets”.

However, Mr Ngai did not deliver the Seven Worksheets. Instead, he unilaterally reinterpreted the performance bonus criteria because, Mr Ngai claimed he “knew [the criteria] better” than his manager at Banshing and was “an exceptional CFO”. Mr Ngai allegedly introduced and implemented several deliverables, including a Capital Expenditure policy and Return on Investment framework, amongst other things. In Banshing’s view, Mr Ngai did not fulfil the criteria for the performance bonus as he had not delivered the Seven Worksheets. Accordingly, Mr Ngai was not paid any bonus. Mr Ngai’s employment was subsequently terminated by Banshing.

Mr Ngai then sued Banshing for S$ 200,000 being his performance bonus. He also alleged that Banshing’s Chairman had verbally assured him that his bonus would be paid. Mr Ngai claimed that:

1. Banshing breached the employment contract by failing to agree to the bonus criteria during the probation period;
   
2. Banshing breached the employment contract by not paying the performance bonus;
   
3. He was entitled to the bonus because of the alleged verbal assurances, on the grounds of fraudulent misrepresentation, negligent misrepresentation and estoppel by representation.

Summary of the court’s decision

After a 3-and-a-half-day trial, the court decided that:

1. Even though the bonus criteria was not agreed during the probation period, as required by the employment contract, Banshing did not breach the employment contract. The requirement for the criteria to be “agreed and defined during probation period” was bilateral, and on the facts, Mr Ngai did not take issue with the criteria being agreed after the probation period at the relevant time. In the court’s view, Mr Ngai and Banshing had therefore mutually agreed to modify the timeline for defining the bonus criteria;
   
2. The bonus criteria was the delivery of the Seven Worksheets. As Mr Ngai did not deliver the Seven Worksheets, he was not entitled to the performance bonus, and Banshing did not breach the employment contract by not paying the bonus. Mr Ngai’s unilateral reinterpretation of the bonus criteria did not alter the bonus criteria.
   
3. Even after cross-examination, Mr Ngai could not prove on the balance of probabilities that Banshing’s Chairman made verbal assurances to him that the bonus would be paid. In the court’s view, it did not make sense for Banshing’s Chairman to make such assurances because he was not responsible for deciding whether Mr Ngai would be paid the bonus, and he was also not aware of the Seven Worksheets requirement. Mr Ngai therefore could not prove his claims based on fraudulent misrepresentation and negligent misrepresentation.
   
4. The court dismissed Mr Ngai’s claim based on estoppel by representation as a matter of law, as it is well-established in Singapore that estoppel by representation only functions as a defence but not as a cause of action.

Practical takeaways for employers

The case raises three important practical takeaways for employers:

1. Bonus criteria should be clearly and contemporaneously recorded in writing. Where the employee’s version of events on crucial matters like bonus criteria is pitted against the employer’s, it is critical to have contemporaneous written records. The email correspondence on the Seven Worksheets was preferred by the court over Mr Ngai’s contrary allegations and lack of supporting written evidence. Documenting the bonus criteria and any changes to them should be in writing and agreed by all parties. Ideally, the criteria should be properly understood by all parties. In this case, Mr Ngai was under the mistaken impression that he could vary the criteria so long as he delivered what he alleged was the substance of the criteria.
   
2. Timelines in employment contracts must be taken seriously. In this case, the employment contract required the bonus criteria to be “agreed and defined during probation period”, but because this was not done, it had exposed the employer to potential liability for breach of contract. If an extension of time to define the bonus is agreed, record the agreement and how long the extension of time is for.
   
3. Proper drafting and communication of criteria and expectations for performance bonuses. Salary and bonuses are often a sensitive issue and a potential source of employment disputes. The risk of disputes can be mitigated by clear drafting of salary and bonus clauses in employment contracts and clear communication of the employer’s expectations to employees (with contemporaneous written records as highlighted in takeaway (1)).
