Liberty Mutual Group is an American diversified global insurer and the third-largest property and casualty insurer in the United States. It ranks 77th on the Fortune 100 list of largest corporations in the United States based on 2019 revenue. Based in Boston, Massachusetts, it employs over 45,000 people in more than 900 locations throughout the world. As of December 31, 2020, Liberty Mutual Insurance had $145.377 billion in consolidated assets, $119.420 billion in consolidated liabilities, and $43.796 billion in annual consolidated revenue. The company, founded in 1912, offers a wide range of insurance products and services, including personal automobile, homeowners, workers' compensation, commercial multiple peril, commercial automobile, general liability, global specialty, group disability, fire and surety.
Liberty Mutual Group owns, wholly or in part, local insurance companies in Argentina, Brazil, Chile, China (including Hong Kong), Colombia, Ecuador, India, Ireland, Malaysia, Poland, Portugal, Singapore, Spain, Thailand, Turkey, the United Kingdom, Venezuela and Vietnam.
In the United States, Liberty Mutual remains a mutual company where policyholders holding contracts for insurance are considered shareholders in the company. However, Liberty Mutual Group's brand usually operates as a separate entity outside the United States where subsidiaries are often created in countries where legally recognized mutual company benefits cannot be enjoyed.
In April 2013, Kelly stepped down from the board of directors as chairman.
Liberty Mutual was founded in 1912 as the Massachusetts Employees Insurance Association (MEIA), following passage of a Massachusetts state law requiring employers to protect their employees with workers’ compensation insurance in 1911. The company was founded as a mutual company, under which an insurance company is owned by its policyholders. The first branch office was opened in 1914, and later that year, the company wrote its first automobile insurance policy. The name was changed in 1917 to the Liberty Mutual Insurance Company and, through partnerships, the company began offering full-coverage auto policies.
In 1964, Liberty Mutual Insurance Company began offering life insurance through its Liberty Life Assurance Branch. In 2002, the company converted into its current mutual holding company structure. The conversion was controversial, as it proposed to give policyholders an interest in the mutual insurance company, which some policyholders believed would dilute their interest in the overall company and limit their dividends. A lawsuit was filed, alleging that information provided to policyholders was misleading. Liberty Mutual settled the lawsuit in December 2001, which required additional disclosure and limited certain compensation to company officers and directors. Despite these concerns, the plan was approved by voting policyholders around November 2001. Leveraging the greater flexibility of the mutual holding company structure, Liberty Mutual transformed from a single-line, highly regional insurer to one of the world's leading property and casualty insurance companies.
Growth and acquisitions
Liberty Mutual's growth has been both organic and through acquisition. Early acquisitions were small, but Liberty Mutual has made several large acquisitions over the past decade, including the high-profile acquisition of Safeco Corporation in 2008. Liberty Mutual agreed to acquire all outstanding shares of Safeco for $68.25 per share, for a total transaction price of approximately $6.2 billion. The result of this activity was an increase in revenue from $6 billion to over $30 billion in twelve years. In 1999, the company purchased Wausau Insurance Cos.
Liberty Mutual created a television commercial in 2006 about people doing good things for strangers, reporting that the "overwhelming" positive response they received for the ad led to their decision to create the website The Responsibility Project.Liberty Mutual is also the sole corporate sponsor of the long-running PBS documentary series American Experience and has produced special commercial messages for airing during American Experience broadcasts. In 2011, as part of the company's "Real America" campaign, the company introduced two new commercials featuring Sacagawea and Paul Revere. In 2011, the company began construction of the Liberty Mutual Tower, a 22-story skyscraper as part of its World Headquarters Expansion Project. The building received its certificate of occupancy in June 2013.
In May 2017, Liberty Mutual Insurance completed its acquisition of Ironshore Inc. Hamilton, Bermuda from Fosun International Limited for $2.93 billion. In October 2019, Liberty Mutual acquired Nationale Borg, Nationale Borg Reinsurance, and AmTrust Insurance Spain, which are credit and surety reinsurance subsidiaries of AmTrust Financial Services.

Liberty Mutual Research Institute for Safety
Founded in 1954, the Liberty Mutual Research Institute for Safety has studied the occupational safety and health of workers. Its scientific contributions include machine safeguarding guidelines, the Cornell-Liberty Survival Car, and ergonomic guidelines that have informed the basis for national and international safety standards. More recently, the Institute developed the Workplace Safety Index, which is an annual ranking of the leading causes of the most disabling occupational injuries in the United States.
The Institute's scientists conduct field and laboratory experiments to study the major causes of work-related injury and disability, publishing their results in peer-reviewed scientific literature. Institute findings are the basis for safety programs, recommendations, and software used by Liberty Mutual loss control consultants in order to help policyholders enhance worker safety. The Institute’s work is non-proprietary, and is available to the public.
The Liberty Mutual Research Institute for Safety closed in May 2017, after over six decades of putting it at the forefront of workplace injury prevention

In 2006, Liberty Mutual employees in the Los Angeles area sued claimed that the company failed to pay their overtime salaries. They attempted to certify a class action suit but it was dismissed on technical grounds.
In late 2012, the company won an appeal granting it the ability not to pay employees for work performed on an overtime basis. Liberty relied on an amicus brief filed on behalf of the US Department of Labor. The court decided, based on the amicus brief, that claims personnel are exempt "Administrative Employees" and not eligible for overtime pay. In late 2012, the California Supreme Court depublished a contrary decision on the same issue.
In 2012 and 2013, a series of investigative articles were published in The Boston Globe concerning excessive compensation and questionable weekend trips using the fleet of five long-range corporate jets by its executives.
