On the q&a, said it's possible that there was still some Berry sales weighing on it, other than that, they don't know why.
Very likely is the answer and a reason to buy LNCO v. LINE near-term, as the gap will correct as BRY shareholders exit over time. Let's face it, if they cared about distributions, they would not have been BRY shareholders in the first place.
The reason for the gap is finally revealed (LOL).
LINE holders get paid May 15th.
LNCO holders get paid May 16th.
There you go ;^)
