technical correction; insurance; uniform plans

This bill corrects the text of an existing Arizona law regarding workers' compensation insurance to clarify how insurers and rating organizations must follow state-approved plans. It specifies that while these entities must generally adhere to uniform statistical and classification plans, they are allowed to use their own statistical methods or create specific subclassifications if approved by the state director. The amendment ensures that any new subclassifications or statistical plans are filed for review and approved before they can be used, maintaining consistency in reporting and rate standards.
