Aetna Life & Casualty

Aetna Life & Casualty

Aetna was founded in 1853 in Hartford, Connecticut, by Eliphalet A. Bulkeley as the Aetna Life Insurance Company, initially writing fire and life policies. The company survived the Great Hartford Fire of 1855 and the financial panics of the 19th century before pivoting decisively into accident and health insurance, which became its signature line of business. By the mid-20th century, Aetna was one of the largest diversified financial services companies in the United States, with major positions in health, life, property-casualty, and reinsurance. Aetna's modern investment posture centers on its general account, historically one of the largest institutional portfolios in the country, allocated across public equities, investment-grade corporate bonds, commercial mortgages, and private placements. Following the sale of its property-casualty unit to Travelers in 1996 and the spin-off of its financial services business, Aetna concentrated solely on health insurance and related products. The firm became a publicly traded managed-care organization, administering medical, pharmacy, dental, and behavioral health plans for employers, government programs, and individuals. Known portfolio-level exposures include significant real estate holdings in major US markets and a substantial fixed-income book managed through its Hartford-based treasury operation. At the time of its 2018 acquisition by CVS Health for roughly $69 billion, Aetna employed approximately 50,000 people and served over 22 million medical members (per CVS Health, 2018). Its headquarters remained in Hartford, with major operational hubs in Blue Bell, Pennsylvania, and Phoenix, Arizona. The firm's philanthropic activity operated through the Aetna Foundation, which focused on health equity and community wellness. Aetna's portfolio managers increasingly integrated ESG factors into investment decisions, with a public commitment to responsible investing in healthcare, affordable housing, and community development. Aetna's structural differentiator was its longevity as a regulated insurance entity with a century-scale liability profile — a balance-sheet discipline that shaped an investment approach distinct from asset managers or pension funds. The CVS Health merger ended Aetna's independent existence but created a vertically integrated healthcare model pairing insurance risk with retail pharmacy and pharmacy benefit management, a structure now studied as a template for payer-provider consolidation.
