Statistical Plan Changes — Summary Index

To advise participating companies of changes that impact the seven ISO statistical plans and the Commercial Territory Code Manual (TCM), ISO distributes Statistical Plan Holder circulars on a regular basis and Notices to Manualholders on a quarterly basis.

As an additional reference tool, we are now offering — on a quarterly basis — a Summary Index of Upcoming Statistical Plan Reporting Changes, as a reminder of the mandatory statistical reporting effective dates of changes taking effect within the upcoming two calendar quarters.

The most current Summary Index is attached to circular SD-AL-2012-001/ SP-AL-2012-001, titled Summary of Upcoming Statistical Plan Reporting Changes. If you do not have access to ISO circulars online, click Summary of Index of Upcoming Statistical Reporting Changes (1st Quarter 2012 and 2nd Quarter 2012) to view a PDF file of the Summary Index.

To receive statistical circulars, your company must participate with ISO for Statistical Service for the corresponding line of insurance.
