For 2016, ICNB reported a mere $5027 in first quarter revenues, $0 for the second quarter, and $0 for the third quarter, so I think it's safe to assume that fourth quarter revenues consisted almost totally of Bellissima sales. ICNB reported that those sales took place in the final eight weeks of the quarter, so it was November and December.
You are correct, it does not say it was just December for all the volume. I got that info from all the posts on here when the annual fins came out lower than pumped.
