Concerning payment of expenses from the earnings of retirement system trust funds.

HB 2125 allows Washington's public retirement systems (including those for teachers, police, judges, and state employees) to use interest earnings from their trust funds to cover specific costs. The bill authorizes paying legal expenses (like court costs and expert fees), medical expenses (for member exams), and administrative costs (such as audits and cybersecurity) directly tied to protecting the trust funds from losses. It also permits using trust fund earnings to investigate fraud and recover overpayments, with all recovered funds returned to the relevant retirement system. The bill does not change how retirement benefits are calculated but modifies how certain operational costs are funded. This amendment to RCW 41.50.255 aims to streamline expense management for the state's retirement systems.
