USE OF RULES MANUALS
A general rules manual may show the bureau’s advisory rates, the loss costs calculated by the bureau, or they may be omitted altogether, depending on how open rating has been implemented in that state.

REGULATION OF FORMS
Despite the dramatic changes that have taken place in workers’ compensation in recent years, regulators still require insurers to use the policy forms and endorsements filed by the designated workers compensation rating bureau in 40 of the 44 states that allow private insurers to write workers compensation insurance. All insurers must use the same forms and provide the same coverage(s).
Perhaps one reason for the continuation of this requirement is that workers compensation coverage is basically dictated by state statutes.
