Most valuable accrual rate.
(ii) Most valuable accrual rate. The most valuable accrual rate for an employee for a plan year is the increase in the employee's most valuable optional form of payment of the accrued benefit during the measurement period, divided by the employee's testing service during the measurement period, and expressed either as a dollar amount or as a percentage of the employee's average annual compensation. The employee's most valuable optional form of payment of the accrued benefit is determined by calculating for the employee the normalized QJSA associated with the accrued benefit that is potentially payable in the current or any future plan year at any age under the plan and selecting the largest (per year of testing service). If the plan provides a QSUPP, the most valuable accrual rate also takes into account the QSUPP payable in conjunction with the QJSA at each age under the plan. Thus, the most valuable accrual rate reflects the value of all benefits accrued or treated as accrued under section 411(d)(6) that are payable in any form and at any time under the plan, including early retirement benefits, retirement-type subsidies, early retirement window benefits, and QSUPPs. In addition, the most valuable accrual rate must take into account any such benefits that are available during a plan year, even if the benefits cease to be available before the end of the current or any future plan year.
