Permian Resources to Kinetik Holdings Inc.: Permian Resources sold its oil and gas gathering systems in Reeves County for $180 million in cash, subject to “customary post-closing adjustments”.
Why are royalty owners liable for “customary post-closing adjustments”?
You royalty payments are based on the production from the wells where you have that royalty interest.
If production for those wells was inaccurately recorded and you were paid on that total, you will see the adjustments that fall in line with the revised production numbers.
These adjustments swing both ways - either a positive or negative adjustment can occur
