The Plan Sponsor is changing Cost Reporter Vendors mid-year. What do we need to do?

It is the responsibility of the Plan Sponsor to coordinate the submission of cost data when the Plan Sponsor changes Vendors mid plan year. Keep in mind that the cost data from the first half of the year must be communicated to the Vendor who is covering the second half of the year so that Threshold Reductions and Limit Reductions are not reported twice. Refer to Coordination of Individual Retiree Cost Data in the RDS User Guide and the Changing Cost Reporter Vendors Technical Article for additional information.
