In this question, a bounty was offered. There were already a few good answers one of which was accepted. But during the bounty period I posted an answer which the OP chose as accepted. Note: my answer is NOT the highest 'voted'.
According to this answer, if the bounty period runs out and the bounty giver does not post the bounty, half of the rep points go to the highest scoring answer(s) OR an answer which was accepted during the bounty period (unless the bounty giver specifically chooses to give the bounty).
Now, I have no problem not receiving a bounty, or even any rep points, so my point isn't about that. I would like to know how the system works, did the system give the points to the highest 'voted' answer or if in this case the bounty giver chose to give the bounty to a certain answer (perfectly fine).
