3. What’s the Law? Insurers must file everything.
“Every insurer shall file with the superintendent of insurance every form of a policy, endorsement, rider, manual of classifications, rules, and rates, every rating plan, and every modification of any of them which it proposes to use.”
- Ohio Revised Code § (A)

4. What’s the Law? Insurers must support everything.
“When … the superintendent does not have sufficient information to determine whether such filing complies with sections to of the Revised Code, he may require such insurer to furnish the information upon which it supports such filing.”
- Ohio Revised Code § (A)

5. What’s the Law? Standards For Rates
“Rates shall not be excessive, inadequate, or unfairly discriminatory.”
- Ohio Revised Code § (D)

6. What’s the Law? Public Records
“A filing and any supporting information shall be open to public inspection after the filing becomes effective.”
- Ohio Revised Code § (A)
