DATE CHANGED! SIArb Masterclass Series: Drafting Winning Interest Submissions (23 January 2024, 5.15pm - 8.15pm (GMT +8))
Contact SIArb Secretariat, This email address is being protected from spambots. You need JavaScript enabled to view it.

This in-person masterclass will focus on an often underappreciated, but critical part of international arbitration – interest on amounts awarded. It will treat the subject from two perspectives – crafting persuasive and effective interest submissions, and deciding on those submissions (correctly!).

The masterclass will be given by Jonathan Ellis of HKA in Singapore, a leading quantum expert and Dr Matthew Secomb, a partner at White & Case in Singapore (author of Interest in International Arbitration (2019, OUP)).

Among other things, the masterclass will consider:

- The law applicable to interest, and the conflicts of law issues that attach to it

- Various laws’ approach to interest (common law, civil law, shari’a law)

- The economics of interest, and the economic arguments that can be used on interest

The elements of interest (rate, dates and calculation method)

- Interest as an element of damages
