Who Is Peter Zaffino?
Peter Zaffino is the Executive Chairman of AIG, one of the world’s major commercial insurance companies.
He is recognised for his understanding of insurance risk, underwriting, financial management, technology and large-company transformation. His career has included senior leadership positions at Guy Carpenter, Marsh, Marsh McLennan and AIG.
The official AIG leadership profile says he has more than 35 years of experience in insurance and reinsurance.
His boardroom journey can be compared with other experienced corporate leaders covered by Newstrap, including Richard Haythornthwaite, whose career has also involved major financial institutions and board leadership.
Peter Zaffino’s Age
AIG’s 2026 proxy statement listed him as 59 years old.
His exact date of birth is not included in AIG’s current executive profile or recent proxy statement. Therefore, the most accurate public age reference is the age recorded in the company’s official March 2026 filing.
Education Background
He earned a bachelor’s degree from Boston College.
He later completed an MBA in Finance at New York University’s Leonard N. Stern School of Business, commonly known as NYU Stern.
This combination of economics, business and finance gave him a strong base for a career involving risk, insurance pricing, corporate strategy and financial decision-making.
Early Career at GE Capital
Before joining Marsh McLennan, he held senior positions within GE Capital.
His work there focused on alternative-risk reinsurance. This area helps companies manage risks that may not fit ordinary insurance arrangements.
AIG’s 2026 proxy records his GE Capital career as running from 1995 to 2001.
Rise at Guy Carpenter
In 2001, he joined Guy Carpenter, a global reinsurance brokerage business within Marsh McLennan.
He progressed through senior positions before becoming President and Chief Executive Officer in 2008. He remained in that position until 2011.
Reinsurance helps insurance companies protect themselves against unusually large losses. His work at Guy Carpenter therefore required a detailed understanding of financial exposure, natural disasters and complicated global risks.
Becoming Chief Executive of Marsh
His next important career step came in 2011, when he became Chief Executive Officer of Marsh.
Marsh advises companies on insurance, risk and business resilience. He led the company until 2017.
In 2015, he also became Chairman of Marsh McLennan’s Risk and Insurance Services division, which included both Marsh and Guy Carpenter. This placed him in charge of two important global insurance businesses.

Joining AIG
He joined AIG in 2017 as Executive Vice President and Global Chief Operating Officer.
He was also placed in charge of AIG’s General Insurance business. This role covered important areas such as commercial insurance, personal insurance, underwriting and international operations.
In 2020, he became President of AIG. He joined the company’s board during the same year before becoming Chief Executive Officer in March 2021.
Becoming AIG Chairman and CEO
He became AIG’s CEO at a difficult point in the company’s history.
AIG had faced years of underwriting losses, operational complexity and uncertainty following the global financial crisis. His task was not simply to increase sales. He needed to improve the quality of the company’s insurance portfolio and make its results more predictable.
He became Chairman of the Board in 2022 while continuing to serve as CEO.
His path from operational work to company-wide leadership shares some similarities with Paul Thandi, who also moved through executive management, transformation and board-level positions.
How He Helped Turn AIG Around
AIG credits him with leading a major turnaround during a period of economic uncertainty and changing global risks.
Under his leadership, the company:
- Reversed years of significant underwriting losses.
- Recorded five consecutive years of underwriting profitability.
- Sold businesses that were no longer central to its strategy.
- Strengthened its balance sheet.
- Modernised technology and operating systems.
- Improved underwriting discipline.
- Reduced unnecessary financial volatility.
- Invested in artificial intelligence and data systems.
Underwriting profitability means that an insurer earns more from premiums than it spends on claims and related operating costs. Delivering this result for five consecutive years represented an important improvement for AIG.

Technology and Artificial Intelligence
Technology became an important part of AIG’s transformation.
The company modernised its end-to-end processes, technology infrastructure and data systems. This allowed teams to examine risks more quickly and work with more detailed information.
AIG has also recognised Zaffino as a commercial leader in understanding and applying artificial intelligence.
The purpose of these systems is not simply to automate work. Better technology can help underwriters examine complicated information, recognise patterns and make more informed decisions about insurance risk.
Leadership Style and Work Ethic
His publicly documented leadership approach is based on discipline, careful risk selection and operational excellence.
Instead of chasing growth at any cost, AIG concentrated on writing insurance that could produce sustainable profit. The company also reduced exposure to business areas that created unpredictable results.
This approach required management to understand the possible outcome of each insurance portfolio, including the effect of natural disasters, cyberattacks and other major events.
His career therefore presents him as a detailed, financially focused executive who gives strong importance to risk control and long-term performance.
The career of Alex Dibelius offers another example of a leader whose professional journey combines technical knowledge, finance and high-level investment decisions.
Move to Executive Chairman
In January 2026, AIG announced that he planned to retire as CEO and move into the Executive Chairman position.
Eric Andersen joined AIG as President and CEO-elect in February 2026. The leadership transition was completed on 1 June 2026, when Andersen became chief executive and Zaffino continued as Executive Chairman.
This means Zaffino remains involved with AIG at board level, but he no longer manages the company as its CEO.
Peter Zaffino’s Compensation
The AIG 2026 proxy statement filed with the SEC reported total 2025 compensation of $32,460,049 for his work as Chairman and CEO.
The amount included:
| Compensation type | 2025 amount |
|---|---|
| Base salary | $1,500,000 |
| Stock awards | $14,084,855 |
| Option awards | $4,374,994 |
| Non-equity incentive compensation | $12,000,000 |
| Other compensation | $500,200 |
| Total reported compensation | $32,460,049 |
The total should not be treated as the amount he received entirely in cash. Stock and option awards are reported using accounting values and may depend on vesting conditions, future performance and share prices.
The SEC filing also reported beneficial ownership of 2,177,207 AIG shares as of 31 January 2026. The figure included securities that could become exercisable or vest within 60 days.
Board and Charity Work
Outside his main AIG responsibilities, he serves on the Board of Directors of the Michael J. Fox Foundation for Parkinson’s Research.
He is also a trustee of the Hospital for Special Surgery.
The Peter and Kirsten Zaffino Family Foundation has supported fundraising for Parkinson’s research. The Michael J. Fox Foundation says its Breaking PARkinson’s event has raised more than $23 million since it began.
Public Image
His public image is mainly connected with insurance leadership rather than celebrity life.
He is known as an executive who helped make AIG more stable, profitable and focused. His strongest professional achievements include improving underwriting results, simplifying the company and investing in modern technology.
He is also associated with detailed financial management, risk control and the belief that profitable growth should be supported by strong underwriting standards.
