FR meaning in Accounts and Finance ?

The Federal Register (FR or sometimes Fed. Reg.) is the official journal of the federal government of the United States that contains government agency rules, proposed rules, and public notices. It is published every weekday, except on federal holidays. The final rules promulgated by a federal agency and published in the Federal Register are ultimately reorganized by topic or subject matter and codified in the Code of Federal Regulations (CFR), which is updated annually.

The Federal Register is compiled by the Office of the Federal Register (within the National Archives and Records Administration) and is printed by the Government Publishing Office. There are no copyright restrictions on the Federal Register; as a work of the U.S. government, it is in the public domain.
