Expert Witness Snapshot

Craig has nearly four decades of executive and professional experience gained primarily in the fields of strategy, finance and technology.

Early technical and account management roles in the banking division of a US technology firm were followed by a career change to commercial and subsequently investment banking. This culminated in senior positions involving the building and management of financial markets trading, structured finance and risk functions at the London offices of several international banking groups.

In 1992 Craig founded Guildhall Corporate Advisers through which he continues to operate parallel practices in strategic management and dispute resolution, again with a primary focus on finance and technology both as sectors and as functional disciplines.

His strategic portfolio includes projects for commercial and investment banks; financial infrastructure providers such as OTC clearing and settlement houses; and clients from the airline, energy, mining, professional services and technology sectors. Typically clients seek input on the development of strategy, products and services, or fresh insights into specific challenges facing their organisations.

The dispute resolution practice covers expert witness, commercial mediation, arbitration and expert determination, all disciplines in which Craig holds professional accreditations.

He has been instructed as an expert in civil, criminal or regulatory matters involving the investment, lending, selling or trading of financial instruments or aspects of associated technologies or services. Court attendance has been required in one criminal case and five civil cases.

The majority of instructions can be grouped within two broad categories, namely alleged mis-selling of financial products and matters relating to financial markets trading activities.

Mis-selling cases have related to financial products such as structured loans or securities; and standalone derivatives, hedging instruments, contracts for differences or spread betting contracts.

Trading cases have covered activities of individual traders and related claims under fidelity bond and directorsâ?? and officersâ?? insurances; differences between bank or hedge fund dealers and current or former employers relating to bonuses, profitability or risk-appetite; and individuals trading for their own account using instruments ranging from spread-betting contracts to wholesale instruments traded on margin.

Instruments underlying disputes have included fixed income, currency, and equity OTC and exchange traded derivatives, including contracts for difference or spread betting contracts; foreign exchange contracts; asset-backed securities; loans; structured notes linked to a variety of asset classes; and government, corporate and convertible bonds.

Analysis has included portfolio reconstruction; the valuation or quantification of risks of individual instruments through to entire portfolios; reviews of pre- or post-trade processes; and reviews of risk oversight and approaches to bonus awards.

Other subject matter has included the prospects for the solvent liquidation of a structured investment vehicle; intellectual property or performance issues relating to financial technology; and business models for professional service provision to the financial sector.
