(a) Minimum aggregate loss ratio standard. A Medicare supplement individual or group policy form may not be delivered or issued for delivery unless the individual or group policy form can be expected, as estimated for the entire period for which rates are computed to provide coverage, to return to policyholders and certificate holders in the form of aggregated benefits (not including anticipated refunds or credits) provided under the individual policy form or group policy form, on the basis of incurred claims experience or incurred health care expenses where coverage is provided by an HMO on a service, rather than reimbursement, basis and earned premiums for the applicable period, not including any changes in additional reserves and in accordance with generally accepted actuarial principles and practices:
  (1) at least 75% of the aggregate amount of premiums earned in the case of group policies; or
  (2) at least 65% of the aggregate amount of premiums earned in the case of individual policies.
(b) HMO loss ratio standard. An HMO loss ratio, where coverage is provided on a service rather than reimbursement basis, must be calculated on the basis of incurred claims experience or incurred health care expenses and earned premiums for the period and in accordance with accepted actuarial principles and practices. Incurred health care expenses where coverage is provided by an HMO may not include:
  (1) home office and overhead costs;
  (2) advertising costs;
  (3) commissions and other acquisition costs;
  (4) taxes;
  (5) capital costs;
  (6) administrative costs; and
  (7) claims processing costs.
(c) Calendar-year experience loss ratio standard. For the most recent calendar year, the ratio of incurred losses to earned premiums for all policies or certificates that have been in force for three years or more, as of December 31st of the most recent year, must be equal to or greater than:
  (1) at least 75% in the case of group policies; and
  (2) at least 65% in the case of individual policies.
(d) Filing of rates and rating schedules. All filings of rates and rating schedules must demonstrate that expected claims in relation to premiums comply with the requirements of this section when combined with actual experience to date. Filings of rate revisions must also demonstrate that the anticipated loss ratio over the entire future period for which the revised rates are computed to provide coverage can be expected to meet the appropriate loss ratio standards. For individual or group policies issued before March 1, 1992, the provisions of paragraph (3) of this subsection must be met with respect to expected claims in relation to premiums. For purposes of submitting a rate filing under this section, policy forms, whether for open or closed blocks of business, providing for similar benefits must be combined. But for purposes of the required combination set out in this section, issuers may distinguish between policy forms providing for similar benefits for individuals 65 years of age or over and policy forms providing for similar benefits for individuals under age 65. Once policy forms have been combined, they remain so for all rating purposes. When forms have been combined, a rate revision request must not differentiate between the experience of the individual forms. Where significant inconsistencies between rate levels exist among forms providing similar benefits, some deviation in rate revision must be allowed to reduce the significant inconsistencies.
  (1) Each Medicare supplement policy or certificate form must be accompanied, on submission for approval, by an actuarial memorandum. The memorandum must be prepared and signed by a qualified actuary in accordance with generally accepted actuarial principles and practices, and must contain the information listed in the following subparagraphs:
    (A) the form number that the actuarial memorandum addresses;
    (B) a brief description of benefits provided;
    (C) a schedule of rates to be used;
    (D) a complete explanation of the rating process, including assumptions, claims data, methodology, and formulae used in developing the gross premium rates;
    (E) a statement of what experience base will be used in future rate adjustments;
    (F) a certification that the anticipated aggregate loss ratio is at least 65% (for individual coverage) or at least 75% (for group coverage), which should include a statement of the period over which the aggregate loss ratio is expected to be realized;
    (G) a table of anticipated loss ratio experience for representative issue ages for each year from issue over the period during which the aggregate loss ratio is to be realized; and
    (H) a certification that the premiums are reasonable in relation to the benefits provided.
  (2) Subsequent rate adjustment filings, except for those rates filed solely due to a change in the Part A calendar year deductible, must also provide an actuarial memorandum, prepared by a qualified actuary in accordance with generally accepted actuarial principles and practices, which must contain the following information:
    (A) the form number addressed by the actuarial memorandum;
    (B) a brief description of benefits provided;
    (C) a schedule of rates before and after the rate change;
    (D) a statement of the reason and basis for the rate change;
    (E) a demonstration and certification by the qualified actuary to show that the past plus future expected experience after the rate change, will result in an aggregate loss ratio equal to, or greater than, the required minimum aggregate loss ratio;
      (i) this rate change and demonstration must be based on the experience of the named form in Texas only, if that experience is fully credible, as set out in paragraph (3) of this subsection;
      (ii) this rate change and demonstration must be based on experience of the named form nationwide, with credibility factors as set out in paragraph (3) of this subsection applied, if the named form is used nationwide and the Texas experience is not fully credible;
      (iii) this rate change and demonstration must be based on experience of the named form in Texas only, with credibility factors as set out in paragraph (3) of this subsection applied, if the named form is used in Texas only and the Texas experience is not fully credible;
    (F) for policies or certificates in force less than three years, a demonstration to show that the third-year loss ratio is expected to be equal to or greater than the applicable percentage; and
    (G) a certification by the qualified actuary that the resulting premiums are reasonable in relation to the benefits provided.
  (3) For purposes of this subsection, if a group or individual policy form has 2,000 or more policies in force, then full credibility (100%) must be given to the experience. If fewer than 500 policies are in force, then no credibility (0%) must be given to the experience. The principle of linear interpolation must be used for in force numbers between 500 and 2,000. For group policy forms, the reference in this paragraph to the number of in force policies means the number of in force certificates under group policies. For purposes of this section, "in force" means either the average number of policies in force for the experience period used to support the need for a rate revision, or the number of policies in force as of the ending date of the experience period used to support the need for a rate revision. Once an issuer makes a decision as to which definition it will apply to a particular policy form, the decision is irrevocable. An issuer may submit specific alternate credibility standards to the department for consideration. In order for an alternate standard of credibility to be acceptable for application, the issuer must demonstrate that the standards are based on sound actuarial principles, and that the resulting loss ratios are in substantial compliance with the requirements of subsections (a), (b), and (c) of this section.
  (4) For individual policies issued before March 1, 1992, the expected claims in relation to premiums must meet:
    (A) the originally filed anticipated loss ratio when combined with the actual experience since inception;
    (B) a loss ratio of at least 65% when combined with actual experience beginning with June 1, 1996, to date; and
    (C) a loss ratio of at least 65% over the entire future period for which the rates are computed to provide coverage.
