How it started

History

The company was founded in 1924 by L. Sherman Adams, Charles H. Learoyd and Ashton L. Carr. The company's oldest fund is the Massachusetts Investors Trust, a mutual fund created with $50,000 at the company's inception and reported to be "the world's first open-end investment fund". The company used "brokerage channels" to market its shares to the public and later expanded to $14 million in assets over the next five years. During the stock market crash of 1929 the fund survived an 83% loss and went on to create a second fund in 1934. By 1959, the Massachusetts Investors Trust fund had become the largest mutual fund in the United States.

In 1969, MIT was reorganized as Massachusetts Financial Services (MFS) to reflect the firm's broadened scope of products and services.

In 1976, MFS offered one of the nation’s first national municipal bond funds (Managed Municipal Bond Trust) and in 1981, MFS launched the country’s first globally diversified fixed-income fund (Massachusetts Financial International Trust-Bond Portfolio). In 1986, MFS offered the first closed-end, high-yield municipal bond fund to be traded on the New York Stock Exchange.

In 1982, the company was acquired by Sun Life Financial of Canada.

In 1998, MFS Chairman and Chief Executive, A. Keith Brodkin died, causing a major shift in top management. MFS's assets under management grew from $55 billion to $90 billion between 1997 and 1998, and was reported to be the fastest growing company amongst the twenty largest that funds sold through brokers.
