A. Any retirement bill having a fiscal impact which is enacted by the Legislature and which is approved by the Governor or which otherwise becomes law shall become effective on the first day of July immediately following the regular session during which it was enacted, but only if the enacted bill is concurrently funded as provided by this section and only if the bill is approved as an emergency measure by a vote of two-thirds (2/3) of all members elected to each House. If an enacted bill does not receive a two-thirds (2/3) vote of all members, the law shall become effective on the first day of September immediately following the regular session during which it was enacted. If an enacted bill, including one approved by the Governor, is not concurrently funded as required by this section, then such bill shall not become effective as law.

B. When a retirement bill having a fiscal impact amends a retirement system having employer contributions funded from appropriations by the Legislature, then appropriations for the first fiscal year of effectiveness of the bill, after it becomes law, must include funds to pay the amount determined by the actuarial investigation under paragraph 5 of subsection A of Section 3109 of this title. It is the intent of the Legislature that future appropriations for subsequent fiscal years must include an amount necessary to maintain the actuarial soundness of the retirement system in accordance with the findings of the actuarial investigation. Any limitation on the rate of employer contributions that may be included in a law which is the source of authority for a retirement system affected by this subsection shall be amended to the extent necessary to comply with the requirements of this subsection.

C. When a retirement bill having a fiscal impact amends a retirement system having employer contributions funded wholly or partially from the funds of a political subdivision, that political subdivision shall have a duty to produce funds as necessary to pay all or its proportionate share of the amount determined by actuarial investigation under paragraph 5 of subsection A of Section 3109 of this title.

D. When a retirement bill having a fiscal impact creates a new retirement system, then employer contributions in conformity with paragraph 5 of subsection A of Section 3109 of this title must be made to the retirement system either by direct appropriations by the Legislature or by another source of employer contributions specifically provided for in the bill creating the new retirement system.
