17 C-5 Page 2 of 5 J.M. Kleha Revised PPL Gas Utilities Corporation Working Capital Required for Operation and Maintenance Expenses As of December The Company bills its customers every month. On this basis, there is a considerable span of days between the time gas is furnished to a customer and the time the customer pays for such gas. In many instances, the Company must pay its bills for payroll and other O&M expenses prior to the time it is able to collect the amount due for the service which requires the incurrance of such expenses. Thus, the Company has examined its records to determine, as to the major categories of expense, the average span of days which exists between the time an expense is incurred and the time it must be paid. Exhibit JMK-2, Schedule 1 sets forth the individual components which result in the days lag between payment of expenses and receipt of the related revenues used in the determination of the working capital required for net pro forma O&M expense for the test year ending December 31, 26. No. Description Amount 1 Net pro forma O&M expense (a) $ 183,7 2 O&M expense per day (line 1 divided by 365 days) 53 3 Average lag in days between payment of O&M expenses and receipt of revenue (b) Working capital requirement (line 2 x line 3) _$ 5,176 (a) Total pro forma operation and maintenance expense (D-1) $ 186,952 Less: Non-cash items Uncollectible accounts expense per budget (B-4) 2,916 Gas inventory losses (b) 336 Net pro forma O&M expense $ 183,7 (b) See Exhibit JMK-2, Schedule 1.

This situation exists because revenue is available from customers prior to payment dates of the tax. The factor for the Public Utility Realty tax represents the portion of this tax liability which must be provided by the Company due to payment of the tax before the revenue is available from customers. Exhibit Historic 1, Schedule C-5, pages 6 through 1 reflect the computation of such factors.
