Economic and valuation analysis in disputes where exposure has to be modeled rather than asserted.
Ken spent 25 years inside the world’s most complex markets before he started testifying about them. He structured commodity transactions at Shell Trading and Enron, co-led energy and commodities risk advisory at Deutsche Bank/Bankers Trust, and ran commodity structuring for the Americas at Citigroup, building and valuing the kinds of deals that later end up in front of arbitrators when they go wrong. That is not a coincidence. It is why attorneys call him.
At iDS, Ken leads the economics teams. He puts numbers on financial harm: economic damages, lost profits, valuation disputes, and the market questions underneath them, and builds the models and expert reports that carry those numbers into deposition, arbitration, and trial. His conclusions are constructed the way iDS builds everything, to be tested, because they will be.
Ken came to iDS from Vine Advisors, where he was a Partner, and KEG Capital, the advisory firm he founded. He works with law firms, corporations, financial institutions, private equity sponsors, and government entities, and alongside the full iDS bench, so the economics in a matter connect to the data, forensics, and digital evidence that prove it.
Ken is a distance runner and multisport athlete: three Boston Marathons, five New York Marathons, and a class win at the Houston D10 Decathlon. He knows something about holding a pace under pressure.
“I’ve spent my career building and driving models and understanding markets where the numbers have consequences. Expert work is no different. You start with the facts, make the assumptions explicit, and build an analysis that can withstand scrutiny.” ~ Kenneth E. Gustafson
The earlier you understand the evidence, the better the decisions that follow.
The evidence is abundant. But volume is not access. Access is not understanding. And understanding is not an expert opinion.
Increasingly, evidence is buried across devices, applications, databases, cloud systems, transactions, and other complex sources. It must be found, preserved, made accessible, understood, and interpreted in the context of the matter. And when expert testimony is required, that understanding must support an independent, defensible opinion.
When important evidence surfaces late, assumptions may already have become strategy. When it is identified, tested, and understood early, your team can build its strategy around what can actually be shown. This isn’t just for trial. It is also for TROs, letters rogatory, discovery requests, subpoenas, depositions, summary judgment, mediation, and arbitration.
