1922 - THE EQUITABLE LIFE ASSURANCE SOCIETY

The Equitable Life Assurance Society (Equitable Life), founded in 1762, is a life insurance company in the United Kingdom. The world's oldest mutual insurer, it pioneered age-based premiums based on mortality rate, laying “the framework for scientific insurance practice and development” and “the basis of modern life assurance upon which all life assurance schemes were subsequently based”.

At its peak, Equitable had 1.5 million policyholders with funds worth £26 billion under management, but it had allowed large unhedged liabilities to accumulate in respect of guaranteed fixed returns to investors without making provision for adverse market changes. Many policyholders lost half their life savings, and the company came close to collapse.

Following a July 2000 House of Lords ruling, and the failure of attempts to find a buyer for the business, it closed to new business in December 2000 and reduced payouts to existing members. Lord Penrose's 2004 Equitable Life Inquiry found that the company had made over-generous payouts leading it to be under-funded. A 2007 European report concluded that regulators had focused on solvency margins and failed to consider the increasing risk of accrued terminal bonuses.
