the early 20th century. The 1906 Armstrong Committee investigation in 1905 uncovered the questionable financial practices of several New York life insurance companies. While MassMutual was not a specific target, the investigation required insurance companies to distribute dividends annually, to restrict the size of agents' commissions, and to regulate the nature of their investments. Policies were also required to state the provision upon creation. As the Armstrong Investigation settled, all MassMutual policies issued after October 1, 1907 earned value according to the American Experience Table of Mortality and 3% interest. MassMutual also began to offer new services and policies to attract customers. In 1914, the company instituted a premium waiver in the event of disability, and designed policies with clauses that provided income in the event of disability in 1918. Despite the adverse effects of the influenza epidemic in 1918, MassMutual maintained steady growth.

Eight years later, the firm issued its first pension trust policy in 1938. Postwar years As the Great Depression faded from the United States in 1939, the start of World War II spurred the country's industrial and economic progression, workforce and insurance demands. Former actuary Alexander MacLean began his MassMutual presidency in 1945. Once the United States became heavily involved with World War II and unemployment significantly decreased, MacLean oversaw the development of insurance products and services for workers. The war placed high production demands on the country's industrial workforce. As jobs were quickly created and unions strengthened, MassMutual entered the group marketplace in 1946, offering policies and managing pensions. The first group product was a pension and insurance policy for Brown-Forman Distillers – the Kentucky-based company that produced Jack
