From the press release:
Fueled by strong investment returns, public retirement systems continued to strengthen their funding levels and fine-tune their assumptions, according to an annual study by the National Conference on Public Employee Retirement Systems.
The 2018 NCPERS Public Retirement Systems Study underscores the success of efforts by pension trustees, managers, and administrators to make steady improvements that enhance the sustainability of pension funds, said Hank H. Kim, executive director and chief counsel of NCPERS. ….
…The 2018 study draws on responses from 167 state and local government pension funds with more than 18.7 million active and retired memberships, actuarial assets exceeding $2.5 trillion and market assets exceeding $2.6 trillion. The majority—62 percent—were local pension funds, while 38 percent were state-wide pension funds. NCPERS conducted the eighth annual study in September through December 2018 in partnership with Cobalt Community Research.
