California Labor Codes 3701.5
§ 3701.5 Private self-insured employer payment obligations
(b) If the director determines the security deposit has not been immediately made available for the payment of compensation, the director shall determine the method of payment and claims administration as appropriate, which may include, but is not limited to, payment by a surety that issued the bond, or payment by an issuer of an irrevocable letter of credit, and administration by a surety or by an adjusting agency, or through the Self-Insurers' Security Fund, or any combination thereof. If the director arranges for administration and payment by any person other than the Self-Insurers' Security Fund after a default is declared, the fund shall have no responsibility for claims administration or payment of the claims.
(c) If the director determines the payment of benefits and claims administration shall be made through the Self-Insurers' Security Fund, the fund shall commence payment of the private self-insured employer's obligations for which it is liable under Section 3743 within 30 days of notification. Payments shall be made to claimants whose entitlement to benefits can be ascertained by the fund, with or without proceedings before the appeals board. Upon the assumption of obligations by the fund pursuant to the director's determination, the fund shall have a right to immediate possession of any posted security and the custodian, surety, or issuer of any irrevocable letter of credit shall turn over the security to the fund together with the interest that has accrued since the date of the self-insured employer's default or insolvency.
(d) The payment of benefits by the Self-Insurers' Security Fund from security deposit proceeds shall release and discharge any custodian of the security deposit, surety, any issuer of a letter of credit, and the self-insured employer, from liability to fulfill obligations to provide those same benefits as compensation, but does not release any person from any liability to the fund for full reimbursement. Payment by a surety constitutes a full release of the surety's liability under the bond to the extent of that payment, and entitles the surety to full reimbursement by the principal or his or her estate. Full reimbursement includes necessary attorney fees and other costs and expenses, without prior claim or proceedings on the part of the injured employee or other beneficiaries. Any decision or determination made, or any settlement approved, by the director or by the appeals board under subdivision (f) shall conclusively be presumed valid and binding as to any and all known claims arising out of the underlying dispute, unless an appeal is made within the time limit specified in Section 5950.
(e) The director shall advise the Self-Insurers' Security Fund promptly after receipt of information indicating that a private self-insured employer may be unable to meet its compensation obligations. The director shall also advise the Self-Insurers' Security Fund of all determinations and directives made or issued pursuant to this section. All financial, actuarial, or claims information received by the director from any self-insurer may be shared by the director with the Self-Insurers' Security Fund.
(f) Disputes concerning the posting, renewal, termination, exoneration, or return of all or any portion of the security deposit, or any liability arising out of the posting or failure to post security, or adequacy of the security or reasonableness of administrative costs, including legal fees, and arising between or among a surety, the issuer of an agreement of assumption and guarantee of workers' compensation liabilities, the issuer of a letter of credit, any custodian of the security deposit, a self-insured employer, or the Self-Insurers' Security Fund shall be resolved by the director. An appeal from the director's decision or determination may be taken to the appropriate superior court by petition for writ of mandate. Payment of claims from the security deposit or by the Self-Insurers' Security Fund shall not be stayed pending the resolution of the disputes unless and until the superior court issues a determination staying a payment of claims decision or determination of the director.
