Mo. Rev. Stat. § 105.670

105.670. Cost statement available for inspection — effect of changes (general assembly). — When the general assembly is the legislative body responsible for authorizing a substantial proposed change in plan benefits, a prepared statement regarding the cost of such change shall be made available for its consideration prior to taking final action. Such statement of cost shall be prepared in accordance with section 105.665 and shall be available as public information for at least five legislative days before third reading and passage by either the house of representatives or the senate. The speaker or president pro tem may refer such bill for reconsideration upon receipt of the actuary statement to the committee to which the bill was originally referred. The bill shall retain its place on the calendar as though it had not been recalled. The committee shall report the bill to the house or senate, respectively, within seven calendar days with its recommendations. If any additional substantial proposed change, as defined in subdivision (10) of section 105.660 , in cost or benefits is made by either the house of representatives or the senate or committee thereof, the actuary making the original cost statement shall amend the statement to reflect the additional features prior to the proposal being truly agreed to and finally passed. The plan shall make available to the actuary such information as is necessary to prepare such actuarial statement. The statement of cost shall be filed with the chief clerk of the Missouri house of representatives, the secretary of the senate, and with the joint committee on public employee retirement.
