By BOB CHRISTIEPHOENIX (AP) â¿¿ Before the economy collapsed five years ago, the fund that Arizona uses to pay unemployment benefits topped out at more than $1 billion and was considered one of the healthiest in the nation. The state then burned through the entirety of the fund and went an additional $420 million in the hole as unemployment soared during the Great Recession. The state now wants to issue up to $200 million in bonds to pay back a loan it received from the federal government to plug the gap. The Legislature must approve the bonds, and the legislation is awaiting action in the Senate. The federal government routinely makes loans to states during periods of high unemployment. It gets repaid when rates go back down using revenue from normal employer premiums for the unemployment insurance program. According to the National Conference of State Legislatures, 22 states and the U.S. Virgin islands owe a total of $28.8 billion to the government for unemployment insurance loans, with California leading the way with a $10.7 billion debt. Arizona's unemployment trust fund also remains in the red and is expected to be paying out more than it takes in until next year. The state will owe an estimated $6.5 million to $8 million in interest if it doesn't repay the loan by Sept. 30, and employers will be hit with an increase in what they're required to pay into the unemployment insurance pool beginning in November. The state owes about $311 million to the federal government, down from a peak of more than $420 million, said Mark Darmer, a deputy assistant director at the Division of Employment and Rehabilitation Services. The bonds essentially are a refinancing of that debt at a lower interest rate that also avoids higher employer rates, Senate President Andy Biggs said.
