Employer-computed composite rate.
(6) Employer-computed composite rate. The term employer-computed composite rate refers to a rate for a tier of coverage (such as employee-only, dependent or family) of a QHP that is the average rate determined by adding the premiums for that tier of coverage for all employees eligible to participate in the QHP (whether or not they actually receive coverage under the plan or under that tier of coverage) and dividing by the total number of such eligible employees. The employer-computed composite rate may be used in list billing to convert individual premiums for a tier of coverage into an employer-computed composite rate for that tier of coverage. See 1.45R-4(b)(3).
