NBA Timeouts

[leafsfan1967]

Hey guys. I know in the NBA there are specific rules about mandatory timeouts being taken at specific times in the quarters and rules around which team those timeouts are charged to. My question is what if, let's say, a team runs out of all of its timeouts by the second quarter. The rules stipulate mandatory timeouts still need to be called by the officials in the third and fourth quarters and some will be charged to the team out of timeouts. But would those mandatory timeouts still be taken? If so how can they be charged to the team with no timeouts left?

Would appreciate any help on this. Also if a team had only a 20 second timeout left but was schedule to be charged the mandatory timeout, would they keep the 20 second time out or would the mandatory timeout be charged to that team for their 20 second timeout?
