合同问题，大家帮忙看看！
On the premise that Party B works normally, the salary is 4000 RMB/Month (all the allowances stipulated by the government are included in the salary) + a bonus (agreed separately). 20% of the salary is merit pay and its issuing portion is from 0% to 40% based on the result of evaluation per month.
Party B为劳方，Party A为资方，合同中的 “20% of the salary is merit pay and its issuing portion is from 0% to 40% based on the result of evaluation per month.”到底是什么意思呢，请大家解释下，越清晰越好，谢谢！
