Oklahoma Public Employees Retirement System; authorizing benefit increase for certain retired members. Effective dates.

Added new co-sponsors (Caldwell, Kane) to the House of Representatives, expanding the legislative support for the bill.

Reformatted the bill header and section numbering to reflect its status as a 'Committee Substitute' rather than an 'Enrolled' bill.

Altered the internal line breaks and spacing within the statutory definitions, particularly in the section defining 'Nonfiscal retirement bill', without changing the underlying policy thresholds.

Added a new eligibility category allowing a one-time benefit increase for volunteer firefighters who retired from the Oklahoma Firefighters Pension and Retirement System as volunteers and did not retire as paid firefighters.

Updated the bill's title to explicitly state that it authorizes benefit increases for retired members of the Oklahoma Public Employees Retirement System, reflecting the new volunteer firefighter provision.

Updated the list of sponsoring legislators in the Senate and House to include additional names (Turner, Marti, Dollens, Wolfley, Manger, and Waldron) that were present in the final enrolled version but not in the engrossed draft.

Removed the $100,000 appropriation to the Office of Management and Enterprise Services and the associated emergency declaration.

Added detailed definitions for 'Amendment', 'RB number', 'Legislative Actuary', 'Nonfiscal amendment', and 'Nonfiscal retirement bill'.

Established specific criteria and funding thresholds for authorizing one-time benefit increases based on the retirement system's funded ratio (e.g., 60-80%, 80-100%, or over 100%).
