Tax specialists Will Gay and Ze’ev Deutsch have joined Mosaic Insurance’s transactional liability team, boosting the firm’s tax-risk capability.

Based in London, Mr Gay will be head of International Tax, Transactional Liability for Mosaic, the Bermudian-based global specialty insurer, leading development of tax insurance underwriting on risks arising outside North America.

Mr Deutsch, who joins Mosaic’s New York office as VP, Tax Americas, Transactional Liability, also represents a key addition, the company said.

His role focuses on assessing a broad array of risks for the company’s North American mergers and acquisitions business.

“We’re thrilled to welcome Will and Ze’ev to Mosaic as we grow our transactional team and demonstrate our commitment to solving global tax-risk challenges,” said Jon Hutchens, Mosaic’s global head of Tax, Transactional Liability.

“Will brings deep experience as a practitioner, and a sophisticated approach to underwriting that allows us to meet growing demand for this product and capital in critical regions.”

He added: “Ze’ev’s arrival also comes at a pivotal time for the tax-insurance business. With economic forecasts uncertain, and a renewed emphasis on tax enforcement, clients are increasingly looking to transactional liability insurance to manage tax risk. His expertise on complicated tax issues helps Mosaic offer unmatched service in this space.”

Mr Gay has 18 years of professional experience, focused primarily on cross-border, transactional, and structural tax matters.

Mr Deutsch previously spent six years as a tax lawyer at Fried, Frank, Harris, Shriver & Jacobson LLP, where he focused on fund formation, opportunity zones, cross-border inversions, and other complex tax matters.
