GENERAL TERMS AND CONDITIONS

38. PERIODIC RATE ADJUSTMENT (PRA) - FL&U REIMBURSEMENT (Contd.)

38.5 UNRECOVERED FL&U REIMBURSEMENT ACCOUNT (Contd.)

C. After each current deferred sub-account has twelve (12)

Months of activity, as referenced in 38.5A above, a

Volumetric Amortization Percentage ("VAP") will be

calculated such that each current deferred account will be

amortized in the following twelve (12) Month period. The

VAP will be calculated by taking the final dollar balance

from the current deferred sub-account and dividing this

amount by the WAMIP associated with the applicable deferred

sub-account referenced in 38.5A, and this proceeding

mathematical product will be divided by the sum of the final

nine (9) Months of the estimated next twelve (12) Month

receipt volumes to come up with the Volumetric Amortization

Percentage. To amortize the applicable deferred sub-account

balance ("ADSB"), the VAP will be applied by taking the

current receipt volume multiplied by the WAMIP associated

with applicable deferred sub-account referenced in 38.5A.

Any residual amount left in the applicable deferred sub-

account balance after applying the ADSB will be transferred

to the next deferred sub-account balance.

applicable to Receipt Quantities beginning on the Effective Date
