accuracy of the supporting calculation.
(II) The G-DSMCA filing shall include a complete set of work papers and all

on the following general formula:
(A) current G-DSMCA factor = (current G-DSMCA cost + deferred G-
DSMCA cost) / (forecasted sales customer x monthly service
charge + forecasted sales gas quantity x base rate); and
(B) the G-DSMCA factor will also include the current G-DSM bonus
plus any adjustment necessary to previously approved G-DSM
bonuses;
(II) a detailed schedule showing the computation of interest, as applicable, to
deferred amounts;
(III) the absolute and percentage impact of the proposed rate on the base
rates and on the total monthly bills of typical customers in each customer
class;
(IV) a schedule detailing the allocation of costs to each customer class;
(V) proposed customer notice detailing rate impact and effective date;
(VI) proposed tariff implementing the proposed G-DSMCA; and

(VII) if any gas DSM costs are proposed to be recovered by rate base
treatment, with a return on the unamortized balance, a statement of
current net operating earnings, a detailed calculation of the related
revenue requirement and an attachment detailing any differences in the
proposed rate base treatment compared to the regulatory practices
