Generally accepted accounting principles (GAAP) for state and local governments in the U.S., including their retirement systems, are established by the Governmental Accounting Standards Board (GASB), an independent organization that is a component of the Financial Accounting Foundation. GASB standards are not federal laws or regulations and the organization does not have enforcement authority. Compliance with GASB’s standards, however, is enforced through the statutes of many states and cities, as well as the audit process, when auditors render opinions on the fairness of financial statement presentations in conformity with GAAP.
Many state and local retirement systems publish comprehensive annual financial reports (CAFRs), which comply with the Government Finance Officers Association's Certificate of Achievement for Excellence in Financial Reporting Program. Such reports include investment and actuarial information in addition to GAAP-based financial statements on which an independent auditor has expressed an unqualified opinion.
Beginning in 1994, GASB statements 25 and 27 provided accounting and reporting guidance for public retirement systems and public employers that sponsor a pension plan. Beginning with retirement systems with a fiscal year ending after 6/15/13 and employers that sponsor a pension plan with a fiscal year ending after 6/15/14, new standards will take effect. These new standards are Statement 67, Financial Report for Pension Plans, and Statement 68, Accounting and Financial Reporting for Pensions.
In addition to financial reporting, typical public retirement system accounting responsibilities include contribution accounting and reporting, internal accounting, investment accounting, and auditing.
GASB Statements No. 67 and 68 were developed after a review of Statements No. 25 and 27 which began in 2006. They took effect as the new standards for public pension accounting and reporting in 2013 and 2014, respectively.
