In short

What is economic damages and loss quantification?

Economic damages are the financial loss caused by a breach of contract, a tort, a shareholder dispute or an IP infringement. Quantifying them means building the but-for scenario, what would have happened without the wrong, and measuring lost profits, lost value or extra costs against what actually happened, in a form a court or tribunal can test.

When clients call us

The moments this work is for.

01

A contract has been breached

You want the loss measured on a basis the tribunal will accept, before you decide how to proceed.

02

A claim has been made against you

You want an independent view of quantum, and a critique of the claimant’s numbers.

03

IP or a business has been harmed

Infringement, lost customers or interruption needs the loss in value measured.

Forensic accounting, a partnership dispute.

“There was nothing new adduced from Mun during his cross-examination that altered what was stated in Mun’s report.”
“…the court is of the view that’s (sic) Mun testimony and expert reports are to be preferred. Mun offered a more objective and balanced analysis…”

The same matter, on appeal.

“We agree with the Judge that Mun’s evidence should be preferred. Mun’s evidence was more credible and objective, and the conclusions he reached were well-reasoned and supported by the evidence.”

    Questions

    What clients ask about economic damages.

    What are economic damages?

    Economic damages are the measurable financial losses caused by a wrong, such as lost profits, loss in the value of a business or asset, and additional costs incurred.

    What is a but-for analysis?

    A but-for analysis models what would have happened if the breach or wrong had not occurred, and compares it with what actually happened. The difference, adjusted for mitigation and timing, is the loss.

    What is the difference between lost profits and loss of value?

    Lost profits measure the earnings lost over a period. Loss of value measures the fall in the value of a business or asset as a whole. Which applies depends on the facts and the legal basis of the claim, and the two must not be double-counted.

    Can you work for either the claimant or the respondent?

    Yes. The expert’s duty is to the court or tribunal, so the analysis is the same whichever party gives the instruction.

    Do you work on arbitrations?

    Yes, including matters before the Singapore International Arbitration Centre, as well as the Singapore courts.
