Maurice Raymond "Hank" Greenberg (born May 4, 1925) is an American business executive and former chairman and chief executive officer of American International Group (AIG).
Greenberg was born into a Jewish family in Greenwich Village, New York City. His father, Jacob Greenberg, died when Hank was six and his mother, Ada Rheingold, married a dairy farmer.
Greenberg served in the United States Army in Europe during World War II, participating in Operation Overlord at Normandy, the liberation of Dachau concentration camp, and in the Korean War, rising to the rank of captain. He received the Bronze Star, and the French Legion of Honour as a result of his military service in the European theatre of World War II.
Greenberg attended the University of Miami, where he was a member of Sigma Alpha Mu fraternity, and received his bachelor's degree in 1948. In 1950, he obtained his law degree from New York Law School. He was admitted to the New York Bar in 1953 but did not practice law. He holds honorary degrees from Brown University, Middlebury College, New York Law School, and The Rockefeller University.
In 1962, Greenberg was named by AIG's founder, Cornelius Vander Starr, as the head of AIG's North American holdings after working for Continental Casualty Company, a unit of CNA in Chicago. In 1968 Starr picked Greenberg as his successor. Greenberg held the position until March 2005, when he retired from AIG and was replaced by Martin J. Sullivan. Greenberg was a social friend and client of Henry Kissinger. In 1987, he appointed Kissinger as chairman of AIG's International Advisory Board.
In 2008, he appeared on ABC's Good Morning America, criticizing the board of directors of AIG. In an interview with Reactions magazine in March 2010, serialized over three parts, Greenberg stated that he did not condone AIG's strategy of selling non-core assets to pay back the United States government, and believed the terms under which AIG was provided access to bail-out funds needed to be renegotiated.
He is chairman and chief executive officer of C.V. Starr, a global insurance and investment organization that is named for the founder of AIG, Cornelius Vander Starr. He joined C.V. Starr as vice president in 1960 and was given the additional responsibilities of president of American Home Assurance Company in 1962. He was elected director of C.V. Starr in 1965, chairman and chief executive officer in 1968 and continues in that role. Greenberg is also the chairman of the board of directors and managing director of Starr International Company Inc. C.V. Starr and Starr International are collectively known as the Starr Companies. Greenberg was named the most connected business executive in New York by Crain's New York Business.
In February 2014, Greenberg led a group through Starr Investment Holdings that acquired health insurance claims processor MultiPlan Inc. for around $4.4 billion. This group, on May 5, 2016, sold MultiPlan Inc. to Hellman & Friedman for approximately $7.5 billion. Under Greenberg's leadership, Starr has invested more than $1 billion in China since 2005. Starr led the IPO for the People's Insurance Company of China (PICC), and acquired Dazhong Insurance, the first privatization of a state-owned insurance company.
In August 2009, the U.S. Securities and Exchange Commission charged Greenberg for his involvement in alleged fraudulent accounting transactions that inflated AIG's finances. Without conceding or denying the SEC charges, Greenberg agreed to pay $15 million in penalties.
The New York Attorney General brought civil fraud charges against Greenberg in May 2005, charging him with engaging in fraud to exaggerate AIG's finances. On September 13, 2016, the fraud case against Greenberg came to trial in a state courthouse in Lower Manhattan. The New York State trial counsel said a guilty verdict was needed to "send a message to CEOs of other companies" that "you can't do this sort of thing." The case was resolved on February 10, 2017, subject to a settlement in which Greenberg admitted to fraud and agreed to pay $9 million.
In late 2011, Greenberg's Starr International announced a lawsuit against the federal government. According to Reuters, the lawsuit requested $55.5 billion in damages against the government stemming from the government's financial bailout of AIG in 2008. Following a trial in Fall 2014, the Court of Federal Claims ruled in June 2015 that the federal government acted without authority, but did not award any damages. On appeal, US Court of Appeals for the Federal Circuit threw out the original case, ruling that Starr lacked standing to bring the case, holding that standing belonged solely to AIG, which had not sued. The Supreme Court declined in 2018 to review the case. The market value of the 79.9% of AIG common stock the government acquired on the day the government agreed to loan AIG up to $85 billion was $55.4 billion. By the end of 2012, AIG had repaid all of its loans and the government had made a $17.7 billion profit on the AIG equity it had acquired as a result, plus $6.7 billion in interests and fees.
In November 2012, a Manhattan court dismissed Greenberg's claims that the Federal Reserve Bank of New York breached its fiduciary duties to AIG shareholders. The ruling was upheld in appeals court in January 2014.
In July 2013 Greenberg filed a civil lawsuit against New York Attorney General Eliot Spitzer alleging that Spitzer made repeated defamatory statements against him. In November 2020, a judge dismissed Greenberg's defamation case against Spitzer.
In December 2013, Greenberg filed a complaint with the New York State Joint Commission on Public Ethics alleging that New York State Attorney General Eric Schneiderman had violated the state's public officer's law by making disparaging comments about him that could potentially taint a jury selection in any trial.
In 1990, Greenberg was appointed by Zhu Rongji, then Mayor of Shanghai, to be the first chairman of the International Business Leaders' Advisory Council for the Mayor of Shanghai. In 1994 Greenberg was appointed senior economic advisor to the Beijing municipal government. He was awarded "Honorary Citizen of Shanghai" in 1997. He is a member of the advisory board of the Tsinghua School of Economics and Management, a member of the International Advisory Council of the China Development Research Foundation and China Development Bank. Greenberg was appointed as a member of the Hong Kong Chief Executive's Council of International Advisers from 1998 to 2005. He is a member of the US-China Business Council, honorary chair of the U.S.-China Policy Foundation and is vice-chairman of the board of directors of the National Committee on United States – China Relations. Greenberg sits on the steering committee of the China–United States Exchange Foundation. The Maurice "Hank" Greenberg Scholarship, administered in his name by the US–China Education Trust, supports the studies of ten Chinese students from low-income families each year at Yunnan University. Greenberg was presented the Friendship Medal for Contribution to China's Reform by President Xi Jinping in 2018.
In July 2022, Greenberg announced the founding of a group composed of senior U.S. business and policy leaders who share the view that the United States should engage more constructively with China. Greenberg stated, "The deteriorating state of affairs between the U.S. has destabilized the most important bilateral relationship in the world," and the new group is intended to "help foster a meaningful but frank exchange between the U.S. and Chinese governments on issues of mutual concern."
He is founding chairman of the U.S.-Philippine Business Committee, chairman emeritus of the US-ASEAN Business Council and chairman of the U.S.-Korea Business Council. Greenberg has served on the board of directors of the New York Stock Exchange, the President's Advisory Committee for Trade Policy and Negotiations, and the Business Roundtable and is a member of the Board of Directors of the Peterson Institute for International Economics. He was a director of the Federal Reserve Bank of New York from 1988-1995 and served as its Chairman 1994-1995. He was awarded "CEO of the Year 2003" by Chief Executive magazine.
