Good question! I don't understand it either.

There's a daily budget of 7,124 HBD. 1,586 is paid to workers.
5,538 HBD (7124 minus 1586) was added to the fund yesterday. This is exactly the amount that is added to the fund due to the return proposal. However, this money came from the fund itself so how can the fund increase by this amount? Can anyone explain this?
