 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, the allocation factors must be adjusted to exclude customers that are exempted from the payment of fixed recovery charges. In accordance with the financing order, costs allocable to these exempted customers (i.e., the CARE and FERA FRC customer classes) will be reallocated to the remaining FRC customer classes on an equal-cents per kWh basis as shown below. In 2024, these exempt customers accounted for approximately 10.4% of total energy deliveries and approximately 30.5% of deliveries to the residential domestic FRC consumer classes.
