我是问的公司的NTUC rep,你也可以直接Email NTUC吧。比较有可能是下面的问题:
To be eligible for NTUC FairPrice Rebates and Dividends, you must sign up as a NTUC FairPrice member through the subscription of 20 shares at S$1 each and a one-time entry fee of S$3.
Alternatively, you can sign up under its "Join Now Pay Later" scheme for which the subscription of 20 shares at S$1 each will be deducted from Rebates earned (if any).
估计你sign up的时候那个人忘了让你填这个share的form
