At any time during a dispute or crisis, Deloitte’s qualified expert witnesses provide an independent assessment of potential damages. Our methodologies employ a risk-based approach, and are underpinned by vigorous research, and our breadth of experience. We make the complex, simple, leading the way to successful dispute resolution.

Expert witness testimony: Our professionals are skilled communicators in trials and other dispute resolution forums with years of experience testifying before judges, juries, and arbitrators in complicated areas of business, economics, and finance. We can also assist in screening, coordinating, and preparing other expert witnesses.

We’re experienced in assisting clients and their counsel with damages relating to international commercial disputes and arbitrations, including determining and proving loss, challenging alternatives, and determining foreseeability and mitigation.

We provide a seamless and integrated service across all aspects of the class action lifecycle. This ranges from assessing the type of documents required to be preserved (including those that may impact the assessment of potential damages), document review, developing a sound and defensible damages theory, incorporating technology and analytics to quantify potential damages on a class-member by class-member basis, to developing and administering the claims management process. The ability to have one service provider assist throughout the class action lifecycle ensures efficiencies and ease of coordination.

• M&A/post-purchase-price disputes: Using our extensive Canadian and international experience in purchase and sale agreement disputes, we analyze underlying records, research complex accounting questions, and interpret contractual modifications of generally accepted accounting principles (GAAP). We consult with buyers and sellers, working as an independent arbitrator or rendering expert witness opinions in breach-of-representation litigation matters.
