(b) Discontinuance of a consolidated employer record. Two or more employers that have established and maintained a consolidated employer record will be permitted to discontinue such consolidated record only if the individual employers agree to an allocation of the consolidated employer record and such allocation is approved by the Director of Policy and Systems. The discontinuance of the consolidated record shall be effective commencing with the calendar year following the year of the Director of Policy and Systems' approval.
