Hebrew to English Bus/Financial Finance (general)

Hello,

בתום התקופה המפקיד יקבל מענק...

The text is a detailed description of the terms of an investment in a type of deposit tracking certain stocks. At the end of the period, the depositor receives a מענק based on the performance of the stocks during the period, in addition to the original principal.

Maybe this is equivalent to a "coupon"?

Thanks!
