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.

SB 2613 requires convention center authorities in Tennessee to submit an annual financial audit to the municipality that authorized their organization by January 1 each year. This bill directly affects convention center authorities and the local governments that granted them permission to operate. The key provision amends Tennessee law to mandate this annual audit filing, replacing the previous requirement with a specific January 1 deadline. The change applies to all convention center authorities operating under Tennessee Code Annotated Title 7, Chapter 89. The bill focuses on transparency by requiring municipalities to receive these audits annually.
