House Bill No. 406, introduced by Representative Berault, aims to address the correction of administrative errors within the Assessors' Retirement Fund. The bill enacts R.S. 11:1473, which mandates that when an administrative error leads to either the overpayment or underpayment of benefits, the board of trustees must adjust the payable amount accordingly and take necessary actions to rectify the error. Specifically, if an underpayment occurs due to an error made by a person compensated by the system, the correction will include the payment of interest at the system's valuation interest rate. Conversely, in cases of overpayment, the board is required to recover the excess amount within a reasonable timeframe and must notify the benefit recipient of the overpayment details and the subsequent adjustments to their benefits at least thirty days prior to implementing any reductions.

The proposed law retains existing provisions regarding the board's authority to adjust benefit amounts and recover overpayments while adding specific requirements for interest payments on underpayments and notification procedures for overpayments. The bill is set to take effect upon the governor's signature or after the designated period for gubernatorial action, ensuring that the necessary corrections to administrative errors are handled efficiently and transparently.
