1. EFFECTIVE DATE. Use " rate schedules in effect on January 1 of the years 1960, 1965, 1970 and 1972, and June 30, 1972 for computing bills. A rate schedule is deemed effective on January 1 or June 30 of the year if any energy used on that day could have.bcen billed thereu:ider. Insert the schedule designation and the date on which the new rate schedule first became effective.
2. NET BILLS. Compute all bills on a net basis, i.e., after prompt payment discounts or before delayed payment penalties.
3. MONTHLY BASIS. Compute all bills on a monthly basis. Where rate schedules or any part thereof are quoted on an annual, quarterly, or bimonthly basis, prorate the bills to a monthly basis. . .
4. FUEL ADJUSTMENT. Adjust bills to reflect fuel adjustments, if any, for energy billed on January 1 of each of the stated years, and on June 30 for 1972. Enter the adjustment per kwh, the fuel cost and other pertinent data.
5. METER RENTALS. In computing bills include where applicable any charge made for meter rentals if the majority of customers are required to pay such meter rentals, but exclude such charge if the majority of customers furnish their own meters'.

In either case, state in a footnote the amount of the meter rental and whether or not the majority of customers , furnish or rent meters.

6. LAMP RENEWALS. Compute bills on the assumption that lamp renewal service is not included in the rates. When the charge for lamp rencual service cannot be segregated, state in a footnote that such charge is included in the bills shown.
7. SEASONAL RATES. Do not compute bills under seasonal rates where year-round rates are available. Where year-round rates are not available, compute bills for all seasons- for which there are different rates and state the periods or seasons of.the' year for which each rate is available.
