20-371.
Rate administration
A. The director shall adopt reasonable rules and statistical plans that are reasonably adapted to each of the rating systems on file with the director and that may be modified from time to time. An insurer shall use the rules and statistical plans to record and report its loss and countrywide expense experience in order that the experience of all insurers may be made available,  at least annually,  in sufficient form and detail to aid the director in determining whether rating systems comply with the standards set forth in this article. The rules and plans may also provide for the recording and reporting of expense experience items that are especially applicable to this state and that are not susceptible to determination by prorating of countrywide expense experience.
B. In adopting the rules and plans,  the director shall give due consideration to the rating systems on file with the director,  and,  in order that the rules and plans may be as uniform as is practicable among the several states,  to the rules and to the form of plans used for comparable rating systems in other states.
C. An insurer is not required to record or report its loss experience on a classification basis that is inconsistent with the uniform classification plan.
D. The director may designate an organization the director deems qualified,  other than an insurer that has outstanding obligations under a policy of workers' compensation insurance in this state,  to act as the director's statistical agent. The statistical agent shall assist the director in gathering and compiling workers' compensation experience and performing other related services as the director may specify. The compilations shall be made available subject to reasonable rules adopted by the director,  to insurers and rating organizations,  but no insurer shall be required to file its experience with an organization of which it is not a member.
E. Every insurer shall report its loss and expense experience to the rating organization of which it is a member. The rating organization shall report the insurer's experience to the designated statistical agent. If the rating organization is unable to report the experience of its member insurers to the designated statistical agent,  every insurer that is a member of the rating organization shall directly report its experience to the designated statistical agent.
F. If there is more than one licensed rating organization that meets the requirements of section 20-363,  subsection E,  the director shall designate one of the organizations as the designated rating organization for the purpose of annually making and filing with the director statewide workers' compensation insurance rates that become effective on January 1.
G. The designated rating organization shall annually file its rate filing with the director on or before August 1 for rates that become effective on January 1. The director shall disapprove the filing if it does not meet the standards of section 20-356,  paragraph 1. An insurer transacting workers' compensation insurance in this state shall adhere to the expected loss ratios,  ballast factors and other experience rating factors and to the statewide rates and other rating values made by the designated rating organization for the uniform rate filing,  except that an insurer may deviate from the statewide rate portion of the uniform rate filing according to section 20-359,  subsections A and B.
H. The director may allow the designated statistical agent and designated rating organization to charge licensed rating organizations that operate in this state a reasonable fee for their services. The licensed rating organizations shall pay the fees on a ratable basis.
I. To further the uniform administration of rate regulatory laws,  the director and every insurer and rating organization may exchange information and experience data with insurance supervisory officials,  insurers and rating organizations in other states and may consult with them with respect to rate making and the application of rating systems.
J. If more than one rating organization meets the requirements of section 20-363,  subsection E,  the director shall designate the statistical plan,  classification plan or experience rating plan adopted by the designated rating organization or any other rating organization,  or the plans of another state,  as the uniform statistical plan,  the uniform classification plan or the uniform experience rating plan.
K. If the director does not designate a uniform statistical plan,  a uniform classification plan or a uniform experience rating plan pursuant to this section,  each insurer shall adhere to the statistical plan,  classification plan,  and experience rating plan adopted by the rating organization of which the insurer is a member in this state.
