Regional Authorities and Special Districts - As enacted, revises the "Convention Center Authorities Act of 2009" as the "Convention Center and Agricultural Exposition Authorities Act." - Amends TCA Title 7, Chapter 89.

HB 2320 requires convention center authorities in Tennessee to submit an annual audit of their finances to the municipality that authorized their creation, by January 1 each year. This bill directly affects convention center authorities and the local municipalities that granted them permission to operate. The key provision amends Tennessee law to mandate this annual audit submission to the municipality's governing body, replacing previous requirements with a specific deadline. The bill focuses on increasing financial transparency for these authorities without changing their operational structure or funding.
