A Coordinated, Expert-Led Approach to Transaction Risk—Globally
Lockton Companies today announced the formalization of its global Transaction Liability practice, underscoring the firm’s continued investment in providing clients with a coordinated, expert-led approach to managing transaction risk across all major M&A markets.
The global practice builds on Lockton’s established market position in North America—where the firm has placed more transaction liability policies than any other broker over the past three years—and extends a model centered on technical rigor, consistency, and long-term client partnership across its international footprint. The practice will be co-led by Lockton’s U.S. Transaction Liability leadership team: Josh Halpern, Matt Heinz, Gaurav Sud, and Eric Ziff.
“Transaction liability is a highly technical advisory discipline,” said Josh Halpern, Global Co-Head, Transaction Liability. “As transactions increasingly span jurisdictions, clients need advice that combines deep local market expertise with a globally consistent approach. Formalizing our global platform allows us to deliver that standard of technical excellence wherever deals are being done.”
Senior Industry Leadership Appointed to Guide International Expansion
As part of this global expansion, Lockton announced the appointment of Mary Duffy as Head of Global Expansion and Market Strategy, Transaction Liability. Duffy joins Lockton after 13 years at AIG, where she most recently served as Global Head of Mergers & Acquisitions Insurance, overseeing the largest global transaction liability insurer in the market. She began her career in the sector at a large global broker, where she founded that firm’s North America transaction liability practice.
“Mary brings a rare combination of institutional knowledge, global operating experience, and deep technical credibility,” said Matt Heinz, Global Co-Head, Transaction Liability. “She has been directly involved in the evolution of transaction liability products across regions and market cycles. That perspective is invaluable as we continue to build a platform designed to serve sophisticated clients on a global basis.”
“What drew me to Lockton was the seriousness of its commitment to building a truly global transaction liability platform,” said Duffy. “The firm is investing in technical depth, integration across regions, and a consistent approach to advising clients, rather than simply expanding footprint. That focus on quality and alignment is what enables clients to engage with confidence across borders.”
Asia-Pacific Growth Supported by Leading Regional Expertise
Lockton’s international investment also includes the continued expansion of its transaction liability capabilities in the Asia-Pacific (APAC) region, led by Terence Montgomery, who joined the firm in September. Montgomery previously served as Head of M&A Asia-Pacific at another global brokerage and has extensive experience across 20+ years advising private equity and strategic clients on many of the most complex and high-value transaction liability insurance backed deals across APAC.
“Asia-Pacific is a diverse and highly nuanced market, and success there depends on both regional insight and global connectivity,” said Gaurav Sud, Global Co-Head, Transaction Liability. “Terence brings exceptional expertise across a significant range of jurisdictions and transaction types, and he has quickly become a central part of our global team.”
“Dealmakers in Asia-Pacific are executing increasingly complex cross-border transactions and expect advice that reflects both local market realities and global deal standards,” said Montgomery. “Lockton’s integrated platform allows us to deliver that balance consistently — with technical rigor, a strong focus on execution and coverage, and in a way that aligns with how sophisticated clients operate across the region and globally.”
A Fully Integrated Global Platform, Designed for Cross-Border Transactions
These appointments build on Lockton’s recent global investments in transaction liability, including the establishment last year of dedicated practices in Latin America, led by Bruna Reis, and in India, led by Anand Kaul, as well as continued growth in the UK and the Nordics.
“Our focus has been on building genuine integration rather than a collection of regional teams,” said Eric Ziff, Global Co-Head, Transaction Liability. “Clients should experience continuity in approach, judgment, and service standards regardless of where a transaction originates. This platform is designed to function as a single global team, supported by strong local expertise.”
A Long-Term Commitment to Global Excellence
Lockton expects to continue investing in talent and regional capabilities as transaction liability continues to evolve across markets.
“These appointments represent an important milestone, but they are not an end point,” Ziff added. “We are committed to building depth and excellence in every region in which we operate and to ensuring that clients can rely on the same Lockton experience wherever they are transacting.”
