Topeka ? The Kansas Senate has given first-round approval to a proposal described by supporters as refinancing part of the long-term debt facing the pension system for teachers and government workers.

The bill advanced Thursday would authorize $1 billion in bonds to shore up the financial health of the Kansas Public Employees Retirement System. Senators expected to take a final vote late in the day.

The pension system projects a $9.8 billion shortfall in funding for retirees’ benefits through June 2033. Lawmakers have moved in recent years to close the gap, but the bill would give KPERS an infusion of funds quickly.

The measure anticipates the state taking 10 years longer, until 2043, to close the shortfall while reducing the state’s annual costs. Critics questioned whether such a move is prudent.
