# 229.90 Proportionate shares of overall minimum.

When both the employee and the spouse are entitled to annuities and the overall minimum rate is higher than the railroad formula rate, the overall minimum amount must be divided between the employee and spouse. The employee receives two-thirds of the total O/M rate. The spouse receives one-third of the total O/M rate.
