Oh ok, my bad. It's more a matter of semantics. While they don't actually "own" the Sprint Center, there is no anchor tenant so they have no scheduling conflicts and have an easy time getting events scheduled on favorable dates. They've said on a few occasions that since the building is profitable, they would rather not risk things by bringing in an NBA or NHL tenant.
Here, the Kings rent money will go towards paying off the building so that's 43 dates plus playoffs that AEG won't be able to schedule for the big acts so it's possible that we aren't looking at the same type of investment. Hopefully I'm wrong. Regardless, it's a good thing that they're involved though. At the end of the day, we need the building full as much as possible since user fees are going pay off a big chunk of the bonds and AEG is the group to make sure a building is full.
