Experience Rating: Rating Effective Date (RED)

The Rating Effective Date (RED) appears on a risk’s experience rating worksheet.  It is the earliest date that a specific modification is applied to a policy.

The RED may differ from the policy effective date for reasons including, but not limited to:

  • Short-term policies
  • Cancellations
  • Gaps in coverage
  • Changes in ownership or combinability status
  • Multiple policy effective dates Interstate operations
  • A policy that is longer than one year and 16 days
  • Late receipt of current policy information by the rating organization

Note:  Wrap-up policies are not used to determine the RED.

Rating Effective Date Determination Table

If the risk is…Then the rating effective date is…
single policy intrastate or interstate risk, orA multiple policy intrastate or interstate risk with all policies having the same effective date
The effective month and day of the most recent full-term policy in effect and each policy thereafter unless the date is changed due to a reason listed above.
multiple policy intrastate risk with policies having different effective datesThe effective month and day of the most recent full-term policy in effect with the largest amount of estimated standard premium.
multiple policy interstate risk with policies having different effective datesThe effective month and day of the most recent full-term policy in effect for the state with the largest amount of estimated standard premium.

An experience rating modification will apply for:

  • No less than three months, except for those impacted by changes in ownership and combinability status according to Rule 3
  • No more than 15 months
  • The experience rating modification applies for the full term of the policy if the policy begins on the RED or within three months after the RED.
  • If a policy begins more than three months after the RED, the following procedure applies:
    1. The current experience rating modification applies to the new policy until the date the modification expires.
    2. A renewal experience rating modification applies to the new policy until the date the policy expires.
    3. A new RED may be established.  Usually, this will be the date 12 months after the effective date of the new policy.

Example: 

7/1/19= rating effective date

7/1/20= next rating effective date (policy effective one year)

1/1/20 = new, rewritten policy

1/1/21 = new rating effective date, new mod effective date (policy effective one year)​​

7/1/20 mod is short termed to expire on 1/1/21, concurrent with new rating effective date​
