Acopy of each filing submitted to the Commissioner under subsections (e) and (g)of this section shall also be sent to the Bureau.

(b)        Definitions. Asused in this section, the following terms have the following meanings:

(1)        "Expenses".– That portion of a rate attributable to acquisition, field supervision,collection expenses, any tax levied by the State or by any politicalsubdivision of the State, licensing costs, fees, and general expenses, asdetermined by the insurer.

(2)        "Developedlosses". – Losses (including loss adjustment expenses) adjusted, usingstandard actuarial techniques, to eliminate the effect of differences betweencurrent payment or reserve estimates and those needed to provide actualultimate loss (including loss adjustment expense) payments.

(3)        "Insurer".– A member insurer or group.

(4)        "Losstrending". – Any procedure for projecting developed losses to the averagedate of loss for the period during which the policies are to be effective.

(5)        "Multiplier".– An insurer's determination of the expenses, other than loss expense and lossadjustment expense, associated with writing workers' compensation andemployers' liability insurance, which shall be expressed as a singlenonintegral number to be applied equally and uniformly to the prospective losscosts approved by the Commissioner in making rates for each classification ofrisks utilized by that insurer.

(6)        "Prospectiveloss costs". – That portion of a rate that does not include provisions forexpenses (other than loss adjustment expenses) or profit; and that are based onhistorical aggregate losses and loss adjustment expenses adjusted throughdevelopment to their ultimate value and projected through trending to a futurepoint in time.

(7)        "Rate". –The cost of insurance per exposure unit, whether expressed as a single numberor as a prospective loss cost with an adjustment to account for the treatmentof expenses, profit, and variations in loss experience, prior to anyapplication of individual risk variations based on loss or expenseconsiderations, and does not include minimum premiums.

(8)        "Supplementaryrating information". – Includes any manual or plan of rates,classification, rating schedule, minimum premium, policy fee, rating rule, rate‑relatedunderwriting rule, experience rating plan, statistical plan and any othersimilar information needed to determine the applicable rate in effect or to bein effect.

(c)        Except as providedin subsection (m) of this section, for workers' compensation and employers'liability insurance written in connection with workers' compensation insurance,the Bureau shall no longer develop or file advisory final rates that containprovisions for expenses (other than loss adjustment expenses) and profit. TheBureau shall instead develop and file for approval with the Commissioner, inaccordance with this section, reference filings containing advisory prospectiveloss costs and the underlying loss data and other supporting statistical andactuarial information for any calculations or assumptions underlying these losscosts. Loss‑based assessments will be included in prospective loss costs.

(d)        After a referencefiling has been filed with the Commissioner and approved, the Bureau shallprovide its member insurers with a copy of the approved reference filing. TheBureau may print and distribute manuals of prospective loss costs as well asrules and other supplementary rating information described in subsection (k) ofthis section.

(e)        Each insurer shallindependently and individually determine the final rates it will file and theeffective date of any rate changes. If an insurer decides to use theprospective loss costs in the approved reference filing in support of its ownfiling, the insurer shall make a filing using the reference filing adoptionform. The insurer's rates shall be the combination of the prospective losscosts and the loss multiplier contained in the reference filing adoption form.Insurers may file modifications of the prospective loss costs in the approvedreference filing based on their own anticipated experience. Supporting documentationis required for any upward or downward modifications of the prospective losscosts in the approved reference filing.

(f)         The summary ofsupporting information form shall contain a reference to examples of how toapply an insurer's loss cost modification factor to the Bureau's prospectiveloss costs. Insurers may vary expense loads by individual classification orgrouping. Insurers may use variable or fixed expense loads or a combination ofthese to establish their expense loadings. Each filing that varies the expenseload by class shall specify the expense factor applicable to each class andshall include information supporting the justification for the variation.However, insurers shall file data in accordance with the uniform statisticalplan approved by the Commissioner.

The insurer need notfile anything further with the Commissioner. If an insurer that has filed tohave its loss multiplier remain on file with the Department intends to delay,modify, or not adopt a particular Bureau reference filing, the insurer mustmake an appropriate filing with the Commissioner.

A filing is complete when the required information is furnished orwhen the filer certifies to the Commissioner that the additional informationrequired by the Commissioner is not maintained or cannot be provided.

(i)         To the extent thatan insurer's final rates are determined solely by applying its loss multiplier,as presented in the reference filing adoption form, to the prospective losscosts contained in the Bureau's reference filing and printed in the Bureau'srating manual, the insurer need not develop or file its final rate pages withthe Commissioner. If an insurer chooses to print and distribute final ratepages for its own use, based solely upon the application of its filed losscosts, the insurer need not file those pages with the Commissioner. If theBureau does not print the loss costs in its manual, the insurer must submit itsrates to the Commissioner.

c.         The insurer decidesto use the revision of the prospective loss costs, but wishes to change itsloss multiplier, then the insurer must file a revised reference filing adoptionform before the effective date of the reference filing.

d.         The insurer decidesnot to revise its rates using the prospective loss costs, then the insurer mustnotify the Commissioner before the effective date of the loss costs.
