(i) those expenses which are directly attributable to specific services rendered to a Client Company or group of Client Companies (Departmental Direct Costs),

(ii) those expenses which are attributable to the overall operation of the department and not to a specific service provided to Client Companies (Departmental Indirect Costs) (these expenses include not only the salaries and wages of employees, but also other related employment costs described in Section 2 (b) above), and

(iii) those expenses which are attributable to the operation of other departments of Services as well as to a specific service provided to the Client Companies (Departmental Support Service Costs).

(d) The indirect expenses of the department will not include:

(e) Services will establish annual budgets for controlling the expenses of each service department and those expenses outlined above in Section 2 (d), which are not department specific.

3. Employees in each department will maintain a record of the time they are employed
in rendering service to each Client Company or group of Client Companies. The hourly rate for each employee will be determined each pay period.

4. (a) The charge to a Client Company or a group of Client Companies for a particular service will be the sum of the figures derived by multiplying the hours reported by each employee in rendering such service by the hourly rate applicable to such employee and other direct allocated expenses.

(b) Departmental Indirect Costs as defined in 2(c) (ii) will be loaded onto project codes in proportion to the direct salaries and wages charged to all project codes.

(c) Departmental Support Service Costs as defined in 2(c)(iii) will be allocated to other internal Services departments and the Client Companies using consumption-based billing methods, with these costs then distributed by function. Any costs that remain at Services after this initial billing will be loaded onto project codes in proportion to the direct salaries and wages charged to all project codes.

5. Those expenses of Services that are not included in the expenses of a department under Section 2 above will be charged to Client Companies receiving service as follows:

(a) Incremental out-of-pocket costs incurred for the direct benefit and convenience of a Client Company or a group of Client Companies will be charged directly to such company or group of companies.

(b) The Indirect Corporate Costs of Services referred to above in Section 2(d)(ii) will be allocated among the Client Companies in the same proportion as the charges to the Client Companies, excluding Indirect Corporate Costs.

(c) If the method of allocation of Departmental Indirect Costs (Section 4(b)), Departmental Support Service Costs (Section 4(c)), or Indirect Corporate Costs (Section 5(b)), would result in an inequity because of a change in operations or organization of the Client Companies, then Services may adjust the basis to effect an equitable distribution. Any such change in allocation shall be made only after first giving the Commission written notice of such proposed change not less than 60 days prior to the proposed effectiveness of any such change.

6. On the basis of the foregoing, monthly bills will be rendered to Client Company. Billing procedures and amounts will be open to audit by Client Company and by any regulatory authority having jurisdiction in respect of the Client Company.

7. When services are rendered to a group of Client Companies, costs of such service shall be allocated equitably among the Companies based on the nature and scope of the service rendered according to the formulae outlined in Exhibit II, Supplement.
