Actually it doesn't. If something isn't rated, than it simply wasn't rated, and says absolutely nothing about the content.
Usually things aren't rated because it will obviously be AO/X, so there's little point, but not always.
Regardless, something can't be rated NR. Either it's not NR, or it wasn't rated. Being rated NR is rather contradictory.
