Section 525.70 Annual
Reconciliation
a) In conjunction with a docketed reconciliation proceeding, the
utility shall file with the Commission an annual reconciliation statement,
which shall be certified by the utility's independent public accountants and
verified by an officer of the utility. This statement shall show the
difference between the following:
1) the costs recoverable through the Gas Charge(s) during the
reconciliation year, as adjusted by Factor A and Factor O, and
2) the revenues arising through the application of the Gas Charge(s)
to applicable therms during the reconciliation year.
b) If, after hearing, the Commission finds that the utility has
not shown all costs to be prudently incurred or has made errors in its
reconciliation statement for such reconciliation year, the difference
determined by the Commission shall be refunded or recovered, as appropriate,
under the Ordered Reconciliation Factor (Factor O), along with any interest or
other carrying charge authorized by the Commission.
