The ASA was founded to promote actuarial education and to establish professional standards for actuaries practicing in the United States. However, it was not until 1949 that the ASA merged with two other actuarial organizations to form the SOA, which is now one of the leading actuarial organizations globally.

The formation of the SOA marked a significant milestone in the development of actuarial science in the United States. It brought together actuaries from various practice areas, including life insurance, health insurance, pensions, and investments, under one professional organization. The SOA played a crucial role in setting professional standards, conducting research, and providing educational resources to actuaries.

Another key event that shaped the regulatory landscape for actuaries was the passage of the Employee Retirement Income Security Act (ERISA) in 1974. ERISA introduced comprehensive regulations for employee benefit plans, including pension plans, and required actuaries to play a central role in their design, funding, and administration. This legislation increased the demand for qualified actuaries and highlighted the importance of actuarial expertise in the regulatory framework.

In recent years, the regulatory landscape for actuaries has been further shaped by the increasing focus on risk management and the need for actuaries to assess and manage risks in various industries. The global financial crisis of 2008 highlighted the importance of robust risk management practices, leading to increased regulatory scrutiny and the development of new regulations such as the Dodd-Frank Act in the United States.

Overall, the formation of the SOA and the establishment of other actuarial societies around the world, along with key legislative developments such as ERISA, have played a pivotal role in shaping the regulatory landscape for actuaries. These events have contributed to the professionalization of actuarial science, the establishment of ethical standards, and the recognition of actuaries as trusted professionals in the field of risk assessment and management.
