Each monthly bill shall be adjusted for gas cost as follows:
(a) The city gate rate applicable to current billing month sales shall be calculated to the nearest $0.0001 per Mcf based upon:
(1) A volume factor of 1.0273 determined in establishing the above rate for the distribution system as the ratio of adjusted purchased volumes divided by adjusted sales volumes. Said factor shall be adjusted annually following determination of the actual lost and unaccounted for gas percentage based upon year ended June 30.
(2) The city gate rate applicable to volumes purchased during the current calendar month, expressed to the nearest $0.0001 per Mcf (shown below as “CGR”).
(b) In summary, the gas cost adjustment (GCA) shall be determined to the nearest $0.0001 per Mcf as follows:
GCA =1.0273 x CGR
