I'm working for a company that has an Employee Referral Bonus. Four months ago I referred a colleague and he was hired on. 

I'm looking for the best way to ask for the referral bonus stated in the employee handbook.

Policy:  

> 
> **Employee Referral Bonus**  
>  A referral/recruitment bonus may be paid to full-time employees who refer an individual to Employer that
>  is hired to meet the requirements of an open position. The referred
>  employee must be a full-time employee for three consecutive months
>  before the referral bonus is paid to the referring employee. The
>  referral bonus and its amount are set by senior management.
> 
> 
> 

Any help is welcomed, I'm trying to work on my tact.
