Berkeley Research Group provides expert services ranging from appropriate analyses to objective testimony in matters involving all valuation issues underpinning international arbitration disputes. Our experts identify key issues; appropriately apply relevant theories; and use sophisticated techniques to develop independent, objective, and reasonable analyses and opinions. Our experts have participated in some of the largest and most significant disputes in the world. They have presented oral and written evidence before arbitration panels in proceedings involving disputes between investors and governments concerning investors’ expectations, regulatory regime changes, indirect expropriation, sovereign insurance claims, and damages quantification.

Who We Are

BRG is ranked second globally in the GAR 100 Expert Witness Firms’ Power Index. Our experts have been arbitrators and have held senior-level positions with government agencies, so they have  first-hand knowledge of the key issues of importance to government agencies and arbitration panels. We have been engaged in disputes concerning breach of contract, post-closing purchase price disputes, accounting issues, damages, and other valuation-related matters; as well as a variety of contractual disputes involving share purchase agreements, post-acquisition settlements, supply contracts, joint venture agreements, and build-operate-transfer arrangements, among many others.

When the parties to the dispute, their counsel, or the tribunal decide to retain the services of experts, BRG international arbitration experts and consultants are ready to provide objective, independent, and reasonable advice to claimants, respondents, or arbitration panels.
