hi when does this extra yield offer end?

i really try to understand how this MMF working?
it stated T+1, its already reflected in but the return wasnt tally 5% pa.
i have 2700 inside. Meaning per day shall totalled up at least 30 cents. but i still got 5 cents per day for the past 4 business day well infact the fund already reflected day 2.
this is alot different with other MMF.
MMF should be preety straight foward.
