The Gwinnett County school system’s teacher retirement fund is fully funded, district finance officials recently said.

The fund has about $1.62 billion in assets and $1.54 billion in liabilities, Gwinnett’s chief financial officer Rick Cost told school board members.

Gwinnett has paid about $105 million over the past three years into the account, according to the district’s most recent financial report. Teachers pay 1 percent of their annual salary into the system for the disability fund.

Cost gave his update during a presentation of an independent audit of the school district’s finances. The audit, by Mauldin & Jenkins, found no compliance issues.
