The costs of rendering service by Services will include all costs of doing business including interest on debt but excluding a return for the use of Services' initial equity capital amounting to $20,000. 2. (a) Services will maintain a separate record of the expenses of each department. The expenses of each department will include: (i) those expenses that are directly attributable to such department, and (ii) an appropriate portion of those office and housekeeping expenses that are not directly attributable to a department but which are necessary to the operation of such department. (b) Expenses of the department will include salaries and wages of employees, including social security taxes, vacations, paid absences, sickness, employee disability expenses, and other employee welfare expenses, rent and utilities, materials and supplies, depreciation, and all other expenses attributable to the department. (c) Departmental expenses will be categorized into one of two classes: (i) those expenses which are directly attributable to specific services rendered to a Client Company or group of Client Companies (Departmental Direct Costs), and (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). Departmental Indirect Costs include: (1) Administrative labor costs associated with office and general service employees described in Section 3(a). This would include not only the salaries and wages of these employees but also other related employment costs described in Section 2(b) above. (2) Occupancy costs including rent and utilities. (3) Depreciation. (4) Materials and supplies, telephone use, postage, etc. (5) Other costs attributable to a department. (d) The indirect expenses of the department will not include: (i) those incremental out-of-pocket expenses that are incurred for the direct benefit and convenience of a Client Company or a group of Client Companies and are to be directly charged to such Client Company or group of Client Companies; and (ii) Services' overhead expenses that are attributable to maintaining the corporate existence of Services, franchise and other general taxes, and all other incidental overhead expenses including those auditing fees and accounting department expenses attributable to Services (Indirect Corporate Costs). (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. (a) Employees in each department will be divided into two classes: A. Those employees rendered service to Client Companies (Class A), and B. Those office and general service employees, such as secretaries, stenographers, telephone operators and file clerks, who generally assist employees in Class A or render other house-keeping services and who are not engaged directly in rendering service to a Client Company or a group of Client Companies. In the event that any such office or general service employees are assigned to functions that are attributable to services being performed for Client Companies, such employees shall be reclassified as Class A employees. (b) Expenses set forth in Section 2 above will be separated to show: (i) salaries and wages of Class A employees, and (ii) all other expenses of the department. (c) Class A 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 Class A employee will be determined each month. 4. (a) The charge to 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 Class A 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 Section 2(c)(ii) will be allocated in proportion to the direct salaries and wages charged. 5. Those expenses of Services that are not included in the expense 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)), 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 to 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 Companies. 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 formulas outlined in Exhibit II, Supplement.
