A- PURPOSE
1. The purpose of this standard practice is to provide procedures to ensure a uniform and complete method of preparing and processing:
a. expense offset rate increases,
b. reserve account amortization,
c. Consumer Price Index and rate base offsets.
d. memorandum account establishment and
e. memorandum account amortization advice letters.
2. All regulated water and sewer utilities (Utility) and the Division of Water and Audits (DWA) engineer or analyst (Staff) shall use these procedures, unless a deviation is approved by the Director of DWA. This standard practice incorporates the provisions contained in General Order (GO) 96-B.
B- DEFINITIONS
3. Balancing Account. A deferred debit account carried on the utility's books. When amounts from reserve accounts or memorandum accounts are approved as reasonable by the Commission, those amounts are moved to balancing accounts for recovery.
4. Consumer Price Index (CPI) Offset. A CPI offset adjusts all existing base rates by the Consumer Price Index for All Urban Consumers (CPI-U) to allow for attrition in earnings due to inflation.
5. Expense Offset. An expense offset is a change in rates that allows a utility to pass on to the customers changes in certain costs that are considered to be beyond the utility's control and that are in the public interest to allow the utility to recover. "Utilities will be required to make rate reductions when power costs, property taxes or any of the other expense items normally included in an offset proceeding are reduced."1
6. Memorandum (Memo) Account. A memo account is an accounting device used by a utility to record various expenses it incurs. The utility may later seek authorization from the Commission to recover the recorded amounts by passing them on to consumers in rates. The establishment of a memo account does not guarantee that the utility will recoup the tracked amount, but a utility is precluded from recovering amounts not booked to a memo account. Memo accounts allow the Commission to consider recovery of utility expenses that have occurred in the past without incurring retroactive ratemaking.2
7. Offset Rate. An Offset Rate is a change to the "base rates" that are set in a General Rate Case that the Commission has allowed in order to protect the utilities from the financial impact of substantial unforeseen changes to expenses beyond the utilities' management control.3
8. Preparation Cost. Class C and D utilities may request recovery of the cost of preparing an offset advice letter if no funds were included in the Regulatory Expense authorized in their last General Rate Case (GRC) to cover such preparation costs. Normally this recovery is spread over three years but may be recovered more quickly if justified.
9. Rate Base Offset. A rate base offset allows the utility to adjust its rates to account for a change in utility plant in service that affects rate base. It includes adjustments to associated expenses such as depreciation and taxes and to charges, such as franchise taxes and uncollectables, that depend upon gross revenues.
10. Reserve Account. A reserve account must be used to track offset expenses and revenues except for CPI and rate base offsets.4 This account tracks the incremental change in the underlying offsettable expense, and the additional revenue, or revenue foregone if the offset is a decrease, from the time of the approval of a rate offset until the expense change is included in base rates.
C- SCOPE AND HISTORY
Expense Offsets and Reserve Accounts
11. The most well-known expense offset approved by the Commission was the Energy Cost Adjustment Clause for Southern California Edison.5 It allowed Edison to add a percentage surcharge to its bills to cover increases in fuel costs (oil, natural gas and coal).
12. Resolution No. W-1204, January 6, 1970 approved a "percentage additive" offset to the bills for California Water Service Company to offset the five percent federal income tax surcharge.6 It was followed by a series of resolutions doing the same for other water companies.
13. In 1976 the Legislature enacted section 792.5 of the Public Utilities Code, which required that utilities, when the Commission authorized expense offsets, maintain a reserve account reflecting the difference between actual costs incurred by the utility and the revenue collected through the offset rate increase.
14. Categories of expenses that are eligible to be offset include, for all water and sewer system utilities:
a. purchased power (electricity or natural gas that the utility buys from the energy company),
b. purchased water,
c. groundwater extraction charges (pump taxes).
Class C and D utilities are not covered by attrition and may request an expense offset for: 7,8
e. employee labor,
f. payroll taxes,
g. that portion of contract work that is for operation and maintenance of plant facilities (Class D only),
15. At one time there was a lower limit of 1% and an upper limit of 10% on offsets, but the upper limit was modified in 1979 to simply require individual customer notice for increases over 10%.11 The 1% lower limit, based on the most recent test year or the most recent Annual Report revenues, remains.12 This does not mean that the expense change itself cannot be tracked in the associated reserve account, just that the rates cannot be changed.
16. These guidelines were consolidated in 1984.13 No offsets were allowed if the latest adopted quantities were more than 5 years old (p. 6). This limitation remains.
CPI Offset
17. Each Class C and D water utility earning less than the rate of return authorized in its most recent rate case that is not in its test year and is not subject to a second test year or attrition year adjustment may file once each year by advice letter for a rate increase based on the most recent year-end increase in the Consumer Price Index for All Urban Consumers (CPI-U).14 The Commission has extended this authorization to sewer utilities and to Class B water utilities.15,16 Any utility that misses filing for a CPI increase during a calendar year may not file retroactively during the next year. The utility must pass an earnings test.
18. The Mergers and Acquisition Rulemaking, R.97-10-048, extended the CPI offset to a Class A or B water utility that purchases an Inadequately Operated and Maintained Water System (a system with less than 2,000 service connections that had an outstanding order or citation from the California Department of Public Health when it was acquired) for up to seven years after the purchase date.17
19. There are two distinct types of CPI offsets: the one discussed in this standard practice, originally established by D.92-03-093, March 31, 1992 and the one established by Public Utilities Code Section 455.2 and Commission Resolution No. 4540, June 16, 2003. The latter CPI offset is discussed in Standard Practice U-8-W.
Rate Base Offset
20. Class A utilities may file a rate base offset only if authorized by decision. Class B, C and D utilities may file for a rate base offset without prior authorization.
21. Rate base offsets do not have an associated reserve account.
22. Any rate base offset not authorized in a general rate case requires an earnings test.
23. Rate base offsets are available for used-and-useful utility plant only (unless specifically exempted by the Commission),18 and the offset may be subject to a saturation adjustment if the facilities are over-built.19
Memorandum Accounts
24. A memo account is not recorded in the utility's accounting books; it represents an off-book accounting record. Trackable costs are recorded in a memo account, and they are also recorded in the accounting records normally, in accordance with the Uniform System of Accounts. For example, costs normally expensed would continue to be expensed in the accounting records even though a memo account is set up to track these costs for potential future recovery. Memo accounts track a) expenses, b) the carrying cost and depreciation on capital investments, and c) offsetting revenues, such as insurance proceeds, from the effective date of the account.
25. Memo accounts track costs that the Commission has directed to be tracked and costs that have been approved to be tracked due to events of an exceptional nature that
a. are not under the utility's control,
b. could not have been reasonably foreseen in the utility's last general rate case,
c. that will occur before the utility's next scheduled rate case,20
d. are of a substantial nature in that the amount of money involved is worth the effort of processing a memo account and
e. have ratepayer benefits.21
26. Existing memo accounts include:

27. Individual company memorandum accounts may be authorized by the Commission but, if the accounts are authorized rather than mandated, they must be described in the Preliminary Statement to show that the utility is availing itself of the account:

28. Memo account balances earn at the 90-day commercial paper rate. For Class B, C and D utilities the memo account must be kept on a cash basis not an accrual basis; that is, when an invoice is actually paid, then that expense may be booked to the memo account. Advice letter memo account recovery requests require an earnings test and proof of reasonableness.
Balancing Accounts
29. A balancing account tracks monies that the Commission has authorized for recovery or amortization. When a balance in a reserve account or memo account is approved for recovery, that reserve or memo account balance is moved to a balancing account.22 If the Commission disallows recovery of all or part of a reserve or memo account, the unrecovered amount is amortized below the line.
30. The balancing account is a regulated asset in the accounting records, and in the balance sheet. Costs allowed to be recorded into this account are charged to this account, and surcharges collected to recover these costs are credited to this account, and therefore the surcharges are not credited to a revenue account. The corresponding credit entry is to increase retained earnings, since the purpose of the balancing accounts is to recover expenses that occurred in the past.23
31. Each district has a separate balancing account subaccount for each item to be recovered or amortized. When the balancing account balance reaches zero or a small amount, the utility files to terminate the surcharge or surcredit and the residual amount is moved to another balancing account. Balances in the balancing account earn at the 90-day commercial paper rate.
C - NOTICE
32. Tier 1 advice letters requesting an expense offset for expenses listed in paragraph 14 or a CPI offset do not have to be noticed. The utility should inform its customers with a bill insert or language on the bill that explains the rate change when it first bills for it. 24 All other expense offset requests are Tier 3 filings and require General Rule 4.2 notice and a resolution.
33. A Tier 2 advice letter requesting the establishment of a memorandum account does not have to be noticed because there is no change in rates. The notice will be required when the utility requests recovery of the memorandum account.
34. A Tier 3 rate base offset or memorandum account recovery advice letter must be noticed per GO 96-B General Rule 4.2.
35. Class C and D utilities should not distribute or publish the notice until Staff has reviewed it and informs the utility that it is acceptable. After the notice is distributed or published, these utilities can file the final advice letter.
D - FILING PROCEDURES
Filing for an Expense Offset
36. When a utility incurs or will incur changes in its offsettable expenses resulting in an annual revenue requirement change of over 1%, or if a group of expenses change that, when added together, will exceed 1% in a calendar year, it shall submit a Tier 1 advice letter requesting an offset surcharges to account for those changes and associated changes to other expenses such as franchise tax (see Appendix A). The surcharge(s) shall be established as a special condition to each applicable tariff for each offsettable expense. The special condition shall also memorialize the new adopted quantity for the expense. For other expense offsets, the utility must file a Tier 3 advice letter unless it can provide a citation to a decision (for Class A) or other Commission document approving offset tracking of that type of expense, in which case it is a Tier 2 filing.25, 26 Class B, C and D offset filings require an earnings test.
Amortizing a Reserve Account
37. Pursuant to Section 792.5 of the Public Utilities Code, the utility must establish a reserve account for each item for which expense offsets have been authorized. The reserve account tracks the revenues recovered by the rate offset and the offsettable costs incurred. The average in the reserve account each month accrues interest at the current 90-day commercial paper rate.27,28
38. For Class B, C and D water and sewer service utilities, when the total in the reserve account(s) exceeds (positive or negative) 2% of the gross operating revenue authorized in the last GRC or realized in the last annual report, whichever is higher, the reserve account must be amortized. The reserve account amortization requires an earnings test based on recorded quantities.
39. Reserve account amortization for Class A utilities will be part of the General Rate Case or may be by advice letter when the account over or under collection exceeds 2%, at the utility's option.29
40. Undercollected reserve accounts are amortized by a surcharge on the service charge or the commodity charge, depending upon the type of expense being offset.30 An overcollection in a reserve account is refunded by a surcredit applied only to service charges.31 Surcharges and surcredits are described in the Special Conditions section of the applicable tariff sheets. They become effective on the effective date of the tariff sheet. The maximum length that a surcharge or surcredit will run (in months) must be included in the description. Surcharges or surcredits can terminate before that date if the account has been amortized. The utility files a Tier 1 advice letter to eliminate the special condition.
Filing for a CPI Offset
41. Prior to April 1 of each calendar year DWA will prepare a letter to all Class B, C and D water and sewer system utilities explaining how to apply for a CPI offset, including the CPI percentage increase to use. The utility calculates a CPI offset by multiplying all service and commodity rates in its existing rate schedules by one plus the amount contained in the letter from DWA (or a lesser figure) and files an advice letter to replace the old tariffs with the new tariffs that include the rates escalated by the CPI. The advice letter is Tier 1 (effective upon filing), but still requires an earnings test.32
Filing for a Rate Base Offset
42. Filing for rate base offset recovery requires a Tier 3 advice letter. If the filing is by a Class A utility, the advice letter must refer to the ordering paragraph of the decision that authorizes the filing. The utility shall file an advice letter increasing rates to account for the addition to rate base calculated in accordance with Appendix A. The filing should include all invoices for the project, or, if that would be too voluminous, a listing of the invoices by date paid, company, and service provided with individual amounts, interest accrued, and the total requested.
Establishing a Memorandum Account
43. Memo accounts may be established by filing a Tier 2 advice letter.33 They become effective upon staff approval or on regular statutory notice unless suspended or rejected.34 The advice letter must seek to add a description of the account in the Preliminary Statement (see Appendix B).
44. Each advice letter requesting a new memo account must address the following:
a. The expense is caused by an event of an exceptional nature that is not under the utility's control;
b. The expense cannot have been reasonably foreseen in the utility's last general rate case and will occur before the utility's next scheduled rate case;
c. The expense is of a substantial nature as to the amount of money involved when any offsetting costs decreases are taken into account; and
d. The ratepayers will benefit by the memo account treatment.
45. Some memo accounts are established by Commission order or California law, but, if the establishment is discretionary on the utility's part, require an advice letter filing to be effective.35 Such filing for a preapproved memorandum account is a Tier 1 filing.
Amortizing a Memorandum Account
46. Recovery of a memo account requires a Tier 3 advice letter with full justification of all expenses and a recorded earnings test for the calendar year period during which the expense was incurred. The average monthly balance in the account accrues interest at the 90-day commercial paper rate. 36
47. Surcharges or surcredits for recovery of memo accounts should be spread across all utility services that have benefited from the money spent and booked to the memo account. For example, recovery of DHS fee memo accounts (not water quality memo accounts) should be spread across all services including private fire protection service and reclaimed water service because DHS monitors backflow prevention protections for these services. Recovery of water quality memo accounts, however, should come only from customers who use potable water. Recovery of memo accounts requires a Tier 3 advice letter and resolution, which transfers the balance in the memo account to a balancing account and will institute either a surcharge or surcredit.
E - FORM AND CONTENTS OF THE ADVICE LETTER
48. Class D utilities may elect to furnish only the following information for expense offset rate increases:
a. A written request, including an explanation for the tracked costs;
b. A tabulation of increases in expenses and revenues;
c. Copies of paid bills and work papers showing calculations in support of items to be recovered.
d. For previously established reserve accounts, a summary with supporting work papers showing over or undercollections in the reserve account.
Staff will prepare the necessary paperwork, i.e., the advice letter and Notice to Customers, and provide these documents to the utility. The utility is responsible for the distribution of the notice to its customers.
49. Class B and C utilities may submit two copies of a draft advice letter (proposal), including supporting work papers, to the staff for review (see Appendices B and D). Draft form simply means that the advice letter and the tariff sheets are not numbered, the advice letter is called a draft advice letter, and the date of publication (or distribution) of the Notice to Customers is not filled in. The advice letter must still be typed and all work papers must be legible and logically arranged. The purpose of a draft advice letter is to permit the Division to review the submittal for errors and to eliminate the possible need to reject or supplement a filed advice letter. Exceptions to the draft advice letter procedure will be permitted if a utility is sophisticated enough to file a normal advice letter. Class A utilities shall submit a regular advice letter.
50. Class A, B and C water companies will provide the information in Appendix C, with all supporting work papers showing insurance recoveries, contracts, costs and calculations. Proof of the underlying expense change such as a copy of the invoice or notice of impending cost change must be included. Class A utilities will include a compact disk of all calculations, or e-mail the spreadsheets to water_division@cpuc.ca.gov.
F - CALCULATING OFFSET RATE INCREASES
51. Calculate offset revenue changes by creating an offset summary of earnings (Appendix D). The allowable offsetable amount is added to rate base or expenses. If a rate base offset, the depreciation expense is adjusted by multiplying the incremental plant in service by the last approved composite depreciation rate for the utility or district. The rate of return is that last approved for the utility, or, for multi-district utilities, the last approved for the district, whichever is lower. For Class B utilities the rate of return is the last approved for the utility or district adjusted by the same number of basis points that class C and D rates of return have been adjusted over the same period of time, whichever is lower. For Class C and D utilities, use last authorized return or the midpoint of the latest Class C and D returns published by the Division of Water and Audits adjusted by any deviation to the rate of return made in the utility's last general rate case, whichever is higher.
52. Expense offset rate increases are based on the Adopted Quantities from the last GRC or from the last offset processed.37 The new Adopted Quantities is included in the Special Condition that authorized the offset. The last GRC proceeding should not be more than five years old. Normally, after five years, the utility no longer qualifies for an offset and must file for a GRC if it wants rates modified to account for cost changes. Exceptions to this procedure will be permitted if unique circumstances exist that argue for continued processing of offset filings.
53. As stated earlier, an offset rate increase covers changes in costs since the last rate case or offset. For example, if the electric utility's rates are increased by two cents per kWh, a water or sewer utility can request a rate increase to offset the increased cost of purchased power. The following sample calculation for purchased power illustrates the procedure:
Adopted Quantities (last general rate proceeding)
a. 1,500,000 kWhs at a unit cost of $0.10 per kWh.
b. 2,000,000 Ccf water sales.
New (current) cost of electrical power
$0.12 per kWh
Increased expense
1,500,000 kWh x ($0.12 - $0.10/kWh) = $30,000
The requested increase in revenue is $30,000 and the requested change in rates (assuming the same incremental increase to the quantity rate) is:
$30,000 /2,000,000 Ccf = $0.015 per Ccf
so the tariff sheets would add a surcharge (Special Condition) to the quantity rate of $0.015 per Ccf and a new adopted quantity of $0.12/kWh.
54. Calculation Guidelines for Rate Changes. The following guidelines should be used for calculating the changes in rates.
Water Production Expense Changes for a metered system -
Compute an incremental change in cents per Ccf by dividing the annual amount of the cost increase by the adopted annual sales adjusted for unaccounted-for water. Apply this increase to all blocks if multiple block rates exist.
Water Production Expense Changes for a flat rate system -
Compute an incremental change for the flat rate tariffs similar to the computation of a surcharge by dividing the annual amount to be amortized by the number of actual services and the number of billing periods per year. Adjust the surcharge by the same factors as the flat rate schedule itself (by lot size or service size).
Non-Water Production Expenses - Compute an incremental change in the flat rate tariff similar to the computation above or in the service charge scaled by the capacity factor equivalents for different meter sizes for metered services.
55. The following rate design policy shall be used for offsets unless there is a valid cause for deviation:
a. No change of rate design (percentage of fixed costs in service charge for metered service) shall be made in an offset rate proceeding.38
b. Increases involving water systems that have both flat rate and metered customers should be allocated to those classes so that the metered customer who uses an average amount of water receives the same percentage increase as a flat rate customer.
c. Offsets also apply to Low-Income rate schedules
G - RECOVERY PERIODS
56. Amortization of Undercollection in the Reserve Account (Metered):
a. Surcredits shall apply to service charge only and be designed to return the money as soon as reasonably possible.
b. Reserve and memo account amortization surcharges shall be spread over one year for undercollections of less than 5% of gross revenues, over two years for undercollections of 5% to 10% of gross revenues and over three years for undercollections over 10% of gross revenues. Recovery shall be tracked in a balancing account.
H - EARNINGS TESTS
57. Class B, C and D utilities requesting a CPI offset must pass an earnings test. This test involves the following:
a. If the last General Rate Case authorized a rate of return, create a recorded Summary of Earnings and compare the adopted rate of return to the recorded rate of return. The Summary of Earnings should be adjusted for extraordinary expenses or revenues.39 Using the Summary of Earnings, increase the revenues by the CPI percentage and recalculate the rate of return. If the new return exceeds authorized, the utility will only be eligible for part or none of the increase.
b. If the last General Rate Case authorized a return on margin, calculate the recorded return on margin by taking 1 - Operating Ratio, where the Operating Ratio is equal to Recorded Operating Expenses (operations and maintenance expenses, annual depreciation on non-contributed facilities, amortization of multiyear expenses and applicable taxes: income taxes, property taxes, taxes other than income, payroll taxes) divided by Recorded Operating Revenues increased for the CPI. Again, some expenses may have to be adjusted. Compare this percentage to the authorized return on margin percentage.
58. If the earnings test shows that the utility is over-earning, adjust the requested amount by the over-earning amount. The over-earning amount equals the difference between recorded rate of return and authorized rate of return multiplied by rate base for utilities authorized a rate of return and the recorded rate of margin minus the authorized rate of margin multiplied by the operating expenses for utilities authorized a rate of margin.
I - PROCESSING THE ADVICE LETTERS
59. Expense and CPI offset rate increase advice letters are Tier 1 but still require review. Staff will assure that the utility has properly calculated the offset and met the earnings test as described above.
60. Requests for a new memo account are made by Tier 2 advice letter that should be processed within 30 days. If it becomes evident that the analysis won't be completed in time, the analyst must suspend the review period for the advice letter by sending a suspension letter to the utility prior to the 30th day stating why the review needs to be suspended, inform the tariff unit so that the information can be published in the Commission Calendar, and inform his or her supervisor, who will inform the Branch Chief. Staff will assure that the requested memorandum account meets Commission guidelines as described above.
61. Rate base offset and reserve or memo account recovery advice letters are Tier 3 and will require a resolution. All charges booked to memo accounts must be less than three years old unless the costs are fully justified for being older. Legal expense memo accounts cannot be recovered until the case is closed if the utility was the defendant, and booked costs are normally found imprudent if the utility loses the case. Legal expense memo accounts where the utility is the plaintiff may be recovered prior to closure of the case, subject to refund. After advice letter approval, the analyst or project manager prepares the resolution, if necessary.
62. For all advice letters, the analyst will go through the work papers, verifying all calculations, and requesting additional information as necessary, to ensure that the request is just, reasonable and correct. Even CPI advice letter should be checked for correctness. Appendix E contains a CPI Advice Letter Checklist that can be used for this purpose.
63. For Unanticipated Repair Cost Memorandum Accounts, the "utility should not be permitted to recover costs already factored into it latest rate case, nor should recovery be permitted where a reasonably prudent operator would have taken steps that would have avoided the repair costs."40
64. For Class B, C and D utilities, after review of the draft advice letter, the staff member will advise the utility to file the final advice letter and to notify its customers (if necessary) of the requested rate increase by sending the utility a filled-in copy of the Cover Letter (Appendix F) and the Notice of Proposed Rate Increase (Appendix G); a copy of the filled-out Additional Information sheets (Appendix H) and, if necessary, a corrected draft advice letter (Appendix I). The utility then files the advice letter as specified in General Order No. 96 and notices its customers. The engineer or analyst logs in all customer responses received and replies to them.

G. CATASTROPHIC EVENT MEMORANDUM ACCOUNT (CEMA):
1. PURPOSE: The purpose of the CEMA is to recover the costs associated with the restoration of service and Any Water Co. facilities affected by a catastrophic event declared a disaster or state of emergency by competent federal or state authorities. The balance in the CEMA will be recovered in rates after CPUC review and audit of the recorded CEMA balance. The authority to establish this account was granted in CPUC Resolution E-3238, dated July 24, 1991 and Public Utilities Code Section 454.9.
Should a disaster occur, Any Water Co. will inform the Executive Director of the CPUC by letter within 30 days after the catastrophic event that Any Water Co. has started booking costs in the CEMA.
2. ACCOUNTING PROCEDURE: Any Water Company (AWC) may maintain a memorandum account for its expenses and other recovery/reimbursements in connection with a catastrophic event as defined in Section 454.9. These expenses must be additional or incremental to those allowed in AWC's last general rate case proceeding. AWC shall make entries to this account at the end of each month as follows:
a. Debit entries equal to the incremental or additional amounts recorded in AWC's operations and maintenance and administrative and general expense accounts that were incurred as a result of the catastrophe.
b. Debit entries equal to the depreciation and/or amortization amounts of new or replacement utility plant installed to continue the provision of uninterrupted services to customers.

Rate of Return (Rate Base offsets, CPI offsets and memorandum account recovery only)
1. The recorded rate of return on rate base for the 12 months ending September 1999 is 9.8%.
(Class A utilities only)
2. The recorded weather-normalized rate of return on rate base for the 12 months ending September 1999 is _______.
The weather normalized rate of return is calculated by calculating revenues by multiplying the adopted consumption per customer by the actual number of customers, subtracting the adopted expenses and associated taxes and fees and applying the net revenues to the actual rate base.
Purchased Power
Decision (D.)99-01-001 included Any Water Company rates effective October 1, 1998 of $0.14932/kWh on adopted usage of 24,450,200 kWh. Copies of the Adopted Quantities Tables from D.99-01-001 are attached.
Increases in SCE rates of 0.01018/kWh became effective October 1, 1999. A copy of this tariff (or a bill with the new rate circled) is attached.
Increase in purchased power costs of 24,450,200 kWh x $0.01018/kWh = $248,900.
Ad Valorem taxes have been increased by 0.12% to fund a new school. A copy of the approved county resolution is attached.
Summary of Increased Expenses
Purchased Power $248,900
Ad Valorem Taxes 30,200
Required Rate Increase
$279,100 = 4.02%
$6,950,200
Computation of Rates
Apply purchased power increase to quantity rates and ad valorem increase to service charge rates.
Purchased Power - Quantity Rates
D.99-01-001 included adopted water sales of:
Block 1 0 - 3 Ccf 1,850,160 Ccf
Block 2 Over 3 Ccf 14,560,400 Ccf
16,410,560 Ccf
Increase in quantity rates - use same cents/Ccf increase for all water sales:
$248,900 = $0.0152/Ccf
16,410,560 Ccf
Ad Valorem Tax - Service Charge Rates
D.99-01-001 included adopted customers services of:
5/8 inch meter 50,421
2 inch meter 500
Total 50,921
Total Equivalent 5/8 x 3/4" meters
2" rate = $50.00 = 2.222
5/8" x 3/4" rate 20.25
Total Equivalents
50,921 + (500 x 2.222) = 50,421 + 1,111 = 51,532
$ per meter/year for $30,200 increase
$30,200/51,532 - $0.586/meter/year
$ per meter/month
$0.586/12 = $0.489/meter/month
Let 5/8 x 3/4 increase by 5 cents
Then 2" = 0.0489 x 2.222 = $0.1085 or 11 cents
Check revenues against increase
5,421 x 0.05 x 12 = $3,253
50 x 0.11 x 12 = $ 66
$3,319
$3,319 revenue
3,200 increase
$ 119 overcollection
Reserve Account Undercollection
The reserve account balance as of September 30, 1999 was $5,100. Since this is less than 2% of gross revenues, no recovery is requested.

I. RATE OF RETURN (Rate Base offsets, CPI offsets and memorandum account recovery only)
1. The recorded rate of return on rate base for the 12 months ending ____________________ is _____%.
2. The recorded pro-forma rate of return on rate base for the 12 months ending ____________________ is _____%.
Note: For Class A and B water companies, the recorded rate of return should be relatively easy to obtain. This return should be the latest reasonably available. For Class C and D water companies, the recorded rate of return may be difficult to obtain. However, the engineer should be satisfied that the utility is not over earning.
The pro-forma (or ratemaking) rate of return differs from the recorded rate of return in that the revenues and expenses are normalized for weather. In addition, the pro-forma return reflects the most current expense and tariff rate changes in effect. For Classes B, C and D the pro-forma will not be required.

The effective date of the tariff schedule is requested to be _________.
Notice has been provided as required by GO 96. The Service List is attached to this advice letter (or) This advice letter was served on the same parties a advice letter (or Decision) #___________, dated __________.
The purpose of this advice letter is to include in rates the following increases in costs: (list increases by source, date and amount.)
(Justification for DHS Offset)
Assembly Bill 2995, in adding Section 4019.10 to the California Health and Safety Code (now section 116590 and 116595), directs the Department of Health Services (DHS) and local primacy agencies to charge the utilities within its jurisdiction for all operating costs. The legislation also authorized these costs to be passed on to those utilities' customers. Commission Resolution W-4327, dated March 6, 2002, authorizes any Class B, C and D water company to file the attached rate schedules, and to concurrently withdraw and cancel its present schedules for such service.
Any Water Company, Inc. had duly established the required memorandum account and recorded therein the amount of $_______ representing expenses for DHS or the local primacy agency paid by the company.
Any Water Company, Inc. requests permission to recover the above charges from its ________ customers by adding an annual one time surcharge of $_______ to each customer's bill. Workpapers justifying this charge have been provided to the CPUC Water Branch Staff.
There have been no other compensating changes in the company's revenues, remaining operating expenses or rate base that would offset the impact on earnings of these increases.
The Company's present General Metered Service rates became effective January 1, 1999, pursuant to Decision (D.) 99-01-001, in Application (A.) 98-06-001.
It has been determined that a 4.0% increase in gross revenues amounting to $280,100 is required to offset the increased expenses.
The Commission staff has been provided with supporting workpapers showing the derivation of these quantities.
The actions requested in this advice letter are not now the subject of any formal filings with the California Public Utilities Commission, including a formal complaint, nor action in any court of law.

A. STAFF ANALYSIS
Staff will determine that the proposed improvements represent the appropriate means to solve the problem addressed, or if there is a less costly alternative which would meet the appropriate level of service.
B. CUSTOMER COMMENTS
The utility shall not proceed with the improvements for 20 days after mailing the customer's reaction to the Staff. This will permit Staff review of customer's comments. If there is substantial customer resistance Staff will schedule a public meeting in or near the utility service area so that the utility can further explain the need for the improvements. Staff will present any alternatives to provide the appropriate level of service. The utility shall be responsible for arranging for the meeting place and notification of the meting to all customers.
C. CUSTOMER REJECTION
If the consensus of customer reaction is a desire to retain poor quality (but not unsafe) service rather than pay for improvements, the utility is on notice that the proposed improvements may not be permitted into ratebase. In this instance a formal application should be filed seeking Commission authorization for the disputed improvements.

2 The retroactive ratemaking doctrine prohibits the Commission from authorizing or requiring a utility to adjust current rates to make up for past errors in projections. If a utility includes an estimate of certain costs in its rates and subsequently finds out that the estimate was too low, it cannot adjust future rates to "recoup past losses." City of Piqua v. FERC, 610 F.2d 950, 954 (D.C. Cir. 1979) (quoting Nader v. FCC, 520 F.2d 182, 202 (D.C. Cir. 1975)).

30 Letter from Wesley Franklin to All Class A, B and C Water Utilities, dated September 13, 1983
31 The water utilities originally proposed that all amortization of balancing accounts be applied to the service charge. Staff proposed that the proper way of amortizing water supply expenses be through the commodity charge (Letter from Wesley Franklin to Class A, B and C Water Utilities, September 13, 1983).

33 Many memorandum accounts, such as Security Costs Memorandum Accounts, are more properly established in a general rate proceeding, where the costs can be estimated with precision See D.03-10-070, October 30, 2003. Some memorandum accounts, by Commission ruling, can only be established in a formal proceeding, i.e. Water Quality Memorandum Accounts, (Decision 94-06-033, June 22, 1994, O.P. 3)
34 Southern California Edison Company v. Public Utilities Commission, (2000) 185 Cal. App. 4th 1086.
35 "A small water company, perhaps assisted by the Association or by Branch, would file an advice letter and tariff sheets establishing a memorandum account for unanticipated repair costs." D.92-03-093, March 31, 1992 at 26.
36 One-twelfth of the most recent month's interest rate on Commercial Paper (prime, three months), published in the Federal Reserve Statistical Release, G.13, or its successor publication. See http://www.federalreserve.gov/releases/H15/data/m/cp3m.txt
37 Memorandum from Wesley Franklin to Hydraulic Branch - Supervisors and Seniors, Aug 31, 1983, Subject: Adopted Quantities
38 A change in rate design may require a formal proceeding. At a minimum there must be a substantive justification for the change. See California Manufacturer's Association v. Public Utilities Commission 24Cal.3d 251; 155 Cal.Rptr. 664, 595 P.2d 98.
39 For example, it is common for a small water company owner to take profits out of the system by increasing management salary. This, or any other expense or revenue that is not commensurate with good ratemaking methodology needs to be adjusted.
40 D.92-03-093, March 31, 1992 at 26.
41 Calculate Net to Gross for Debt by including only non-tax items (franchise fees, uncollectables, etc.) that are calculated based on the revenue requirement. Do not include state and federal tax.
42 Even if the plant addition has a non-average service life, it should be depreciated at the last approved composite depreciation rate. A new depreciation rate can be calculated in the next GRC that takes all facilities depreciation lives into account.
