(215 ILCS 5/35A-10)
    Sec. 35A-10. RBC Reports.
    (a) On or before each March 1 (the "filing date"), every domestic insurer shall prepare and submit to the Director a report of its RBC levels as of the end of the previous calendar year in the form and containing the information required by the RBC Instructions. Every domestic insurer shall also file its RBC Report with the NAIC in accordance with the RBC Instructions. In addition, if requested in writing by the chief insurance regulatory official of any state in which it is authorized to do business, every domestic insurer shall file its RBC Report with that official no later than the later of 15 days after the insurer receives the written request or the filing date.
    (b) A life, health, or life and health insurer's or fraternal benefit society's RBC shall be determined under the formula set forth in the RBC Instructions. The formula shall take into account (and may adjust for the covariance between):
        (1) the risk with respect to the insurer's assets;
        (2) the risk of adverse insurance experience with
    
respect to the insurer's liabilities and obligations;
        (3) the interest rate risk with respect to the
    
insurer's business; and
        (4) all other business risks and other relevant risks
    
set forth in the RBC Instructions.
These risks shall be determined in each case by applying the factors in the manner set forth in the RBC Instructions. Notwithstanding the foregoing, and notwithstanding the RBC Instructions, health maintenance organizations operating as Medicaid managed care plans under contract with the Department of Healthcare and Family Services shall not be required to include in its RBC calculations any capitation revenue identified by Medicaid managed care plans as authorized under Section 5A-12.6(r) of the Illinois Public Aid Code.
    (c) A property and casualty insurer's RBC shall be determined in accordance with the formula set forth in the RBC Instructions. The formula shall take into account (and may adjust for the covariance between):
        (1) asset risk;
        (2) credit risk;
        (3) underwriting risk; and
        (4) all other business risks and other relevant risks
    
set forth in the RBC Instructions.
These risks shall be determined in each case by applying the factors in the manner set forth in the RBC Instructions.
    (d) A health organization's RBC shall be determined in accordance with the formula set forth in the RBC Instructions. The formula shall take the following into account (and may adjust for the covariance between):
        (1) asset risk;
        (2) credit risk;
        (3) underwriting risk; and
        (4) all other business risks and other relevant risks
    
set forth in the RBC Instructions.
These risks shall be determined in each case by applying the factors in the manner set forth in the RBC Instructions.
    (e) An excess of capital over the amount produced by the risk-based capital requirements contained in this Code and the formulas, schedules, and instructions referenced in this Code is desirable in the business of insurance. Accordingly, insurers should seek to maintain capital above the RBC levels required by this Code. Additional capital is used and useful in the insurance business and helps to secure an insurer against various risks inherent in, or affecting, the business of insurance and not accounted for or only partially measured by the risk-based capital requirements contained in this Code.
    (f) If a domestic insurer files an RBC Report that, in the judgment of the Director, is inaccurate, the Director shall adjust the RBC Report to correct the inaccuracy and shall notify the insurer of the adjustment. The notice shall contain a statement of the reason for the adjustment.
