RC consumer class in the following manner:

| • |     | first, the servicer will determine the amount necessary to provide for the timely payment of scheduled principal                                                                                                                           
 of and interest on the bonds and operating expenses payable in connection with the bonds (the periodic payment requirement) for each of the two payment periods (each, a payment period) following the true-up adjustment date             
 (adjustment date). The first payment period is the period from the adjustment date through and including first payment date following the adjustment date (the first payment period); the second payment period is the period from the day 
 after the first payment period through and including second payment date following adjustment date (the second payment period);                                                                                                            |

| • |     | next, using the most recently available delinquency and write-off                                                                                                                                                                                    
 experience, the servicer will determine the amount of fixed recovery charges which must be billed during each payment period in order to generate sufficient fixed recovery charges revenues prior to the last day of the calendar month immediately 
 preceding the end of each payment period (collection cut-off date). We refer to this amount as the periodic billing requirement;                                                                                                                     |

| • |     | next, the servicer will allocate the periodic billing requirement for each payment period among each FRC consumer 
 class based on its allocation factor, and                                                                         |

| • |     | finally, the servicer will divide the periodic billing requirement for each payment period by the forecasted                                                                                                                                             
 consumption of each FRC consumer class to determine the fixed recovery charge for the FRC consumer class for the respective payment period. In making such calculations, the servicer will use the most recently approved consumption forecast data and, 
 if applicable, a pending forecast for any period not covered by the most recently-approved sales forecast.                                                                                                                                               |

The above calculations by the servicer will result in two fixed recovery charges for each FRC consumer class, one charge for the first payment period and one charge for the second payment period. The financing order provides that the higher of the two charges for the FRC consumer class will be the fixed recovery charge for that FRC consumer class requested in the true-upadjustment. The initial allocation factors based on the allocation methodology set forth in the Marginal Cost and Revenue Allocation Settlement Agreement and approved in the financing order are set forth in the table below. These initial allocation factors set forth below are estimated. Under the financing order, the initial allocation factors may be adjusted based on sales adjustments contained in a routine true-upadjustment. In addition,
