GENERAL TERMS AND CONDITIONS
3.8. Prior Period Adjustments
Pursuant to NAESB Standards 2.3.7, 2.3.11, 2.3.12, 2.3.13, 2.3.14: The
cutoff for the closing of measurement is 5 business days after the business
month. For treatment of measurement prior period adjustments, treat the
adjustment by taking it back to the production month. A meter adjustment
becomes a prior period adjustment after the fifth business day following the
business month. For reporting measurement prior period adjustments, report
it with the restated line item with new total quantity for the day and the
month. Estimate missing or late measurement data and treat actual as a
prior period adjustment, with the measuring party to provide the estimate.
Measurement data corrections should be processed within 6 months of the
production month with a 3 month rebuttal period. This standard shall not
apply in the case of deliberate omission or misrepresentation or mutual
mistake of fact. Parties’ other statutory or contractual rights shall not
otherwise be diminished by this standard.
