At least one-third of the 90,000 state and local governments produce comprehensive annual financial reports (CAFRs). Due to the lack of  standardization and machine-readability of these reports, the process of aggregating data and comparing financial performance of governmental entities is limited and costly. The Working Group will address this problem by designing schemas and XBRL implementation(s) for open data reporting of state and local government actual financial results.

Working Group Member Resources


The group will pursue opportunities involving Comprehensive Annual Financial Reports (CAFRs), Single Audit packages, state-mandated Annual Financial Reports (AFRs), and responses to relevant Census Bureau financial surveys. The group will support relevant institutions gaining technical understanding and establishing best practices for disclosure modernization for the benefit of US state and local governments, as well as public pension systems.
