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.
