20 CFR §703.120

For policies that are reported to DLHWC on Form LS-570 (Carrier's Report of Issuance of Policy), a separate report of the issuance of a policy and endorsement, provided for by § 703.116, must be made for each employer covered by a policy. If a policy is issued insuring more than one employer, a separate form LS-570 for each employer so covered must be sent to DLHWC in the manner described in § 703.116, with the name of only one employer on each form.
