Hi..guys.. sspn recently sms regarding "loyalty dividend of 0.5% " if deposit rm500 b4 april 31.. my question is

1) the 0.5% is paying for the 2019 rm500 new deposit only / Or 0.5% calculated upon rm500 + all saving amount in my sspn account deposited over years?

2) i see my sspn yearly dividen is about slight over 3% only over these couple years
