Dr Ronnie Barnes, a principal at Cornerstone Research, heads the firm’s international arbitration practice. An expert in accounting, damages and valuation, Dr Barnes specialises in complex valuation methodologies, including the estimation of the cost of capital, the determination of country risk premia, and the valuation of complex financial instruments such as derivatives and structured finance products.

He has provided written and oral testimony in multiple matters involving topics that include the tax treatment of hire purchase contracts; the assessment of damages resulting from the breach of a joint venture agreement; the economic equivalence of various financial derivatives; and the use of derivatives in alleged share price manipulation.

In addition to serving as a testifying expert, Dr Barnes leads teams that support Cornerstone Research’s external academic and practitioner experts.

Dr Barnes is an author of Issues in Cross-Border Valuation and the Implications for Damages Assessments in Investor-State Disputes, and has also published articles on valuation methods and damages analyses. He is a UK-qualified chartered accountant, and previously held positions in accounting and investment banking firms, as well as a consulting firm and in academia.
