“For nearly 40 years, I’ve advised clients on US law and regulation in a wide range of engagements running the full gamut of capital markets products and disciplines, particularly in the cross-border setting. I enjoy helping clients achieve their objectives where there are difficult disclosure, financial or structuring issues, in challenging circumstances and jurisdictions, often in the emerging markets. I work extensively with non-US SEC reporting companies and other companies on strategic, transactional and disclosure matters.”
