S.C. Code Ann. § 38-31-60
The association:
(a) is obligated to the extent of claims existing before the determination of insolvency and claims arising up to the earliest of the following dates:
(iv) Notwithstanding any other provisions of this chapter, except in the case of a claim for benefits under worker's compensation coverage, any obligation of the association to or on behalf of an insured and its affiliates on all covered claims combined shall cease when ten million dollars shall have been paid in the aggregate by the association and any one or more associations similar to the association of any other state or states, to or on behalf of that insured, its affiliates, and additional insureds on covered claims or allowed claims arising under the policy or policies of any one insolvent insurer. If the association determines that there may be more than one claimant having a covered claim or allowed claim against the association, or any associations similar to the association in other states, under the policy or policies of any one insolvent insurer, the association may establish a plan to allocate amounts payable by the association in such manner as the association in its discretion considers equitable.
This obligation includes only the amount each covered claim is in excess of two hundred fifty dollars and is less than three hundred thousand dollars. However, the association shall pay the full amount of any covered workers' compensation claim. The association has no obligation to pay a claimant's covered claim, except a workers' compensation claim, if:
(c) shall allocate claims paid and expenses incurred among the four accounts separately and assess member insurers separately for each account amounts necessary to pay:
(iii) other expenses authorized by this chapter.
The assessments of each member insurer must be in the proportion that the net direct written premiums of the member insurer for the calendar year preceding the insolvency on the kinds of insurance in the account bear to the net direct written premiums of all member insurers for the calendar year preceding the insolvency on the kinds of insurance in the account. Each member insurer must be notified of the assessment not later than thirty days before it is due. No member insurer may be assessed in any year on any account an amount greater than one percent of that member insurer's net direct written premiums for the calendar year preceding the insolvency on the kinds of insurance in the account. If the maximum assessment, together with the other assets of the association in any account, does not provide in any year an amount sufficient to make all necessary payments from that account, the funds available must be prorated, and the unpaid portion must be paid as soon after proration as funds become available. The association may exempt or defer, in whole or in part, the payment of an assessment of any member insurer, if the payment would cause the member insurer's financial statement to reflect amounts of capital or surplus less than the minimum amounts required for a certificate of authority by any jurisdiction in which the member insurer is authorized to transact insurance. Any member insurer serving in the capacity of a servicing carrier for the South Carolina Reinsurance Facility, the South Carolina Windstorm and Hail Underwriting Association, the Medical Malpractice Joint Underwriting Association, or any other involuntary association must not be assessed for the premiums so written, but the assessment must be made directly against the facility, pool, joint underwriting association, or other association. Each member insurer serving as a servicing facility on behalf of the association may set off against any assessment authorized payments made on covered claims and expenses incurred in the payment of the claims by the member insurer;
