In 1990, the Federal Accounting Standards Board (FASB) issued a new rule to require private sector employers to list the cost of future retirement healthcare as a liability on their financial statements. In 2008, these requirements were extended to the public sector by the Governmental Accounting Standards Board (GASB). These rules have led to devastating attacks on retiree health and welfare benefits and have placed additional strain on public sector budgets. This toolkit will explain the impact of these standards; you will learn how to find this liability in public documents and use it to build support for single payer in your state.
