PURPOSE: This rule is intended to prevent a Missouri Public Service Commission regulated electrical corporation, gas corporation, heating company, water corporation (with more than eight thousand (8,000) customers), or sewer corporation (with more than eight thousand (8,000) customers) from subsidizing its nonregulated operations or its affiliates. In order to accomplish this objective, the rule sets forth standards of conduct, financial standards, evidentiary standards, access requirements, training requirements, and recordkeeping requirements applicable to any of these commission-regulated utilities whenever any such entity participates in a transaction with an affiliate (except with regard to HVAC services as defined in section 386.754, RSMo). (1) Definitions.

1. (A) Affiliate means any person, including an individual, corporation, service company, corporate subsidiary, firm, partnership, incorporated or unincorporated association, political subdivision including a public utility district, city, town, county, or a combination of political subdivisions, which directly or indirectly, through one (1) or more intermediaries, controls, is controlled by, or is under common control with the covered utility. This term shall also include the nonregulated business operations of a covered utility.
2. (B) Affiliate transaction means any transaction between a covered utility and an affiliate. Affiliate transactions as defined by this rule shall also include all transactions carried out between any nonregulated business operation of a covered utility and the regulated business operations of a covered utility. An affiliate transaction for the purposes of this rule excludes heating, ventilating, and air conditioning (HVAC) services as defined in section 386.754, RSMo.
3. (C) Affiliate Transactions Report means the filing that each covered utility is required to make with the secretary of the commission no later than each May 15, unless a different date has been agreed to between the commission and the utility within its CAM, providing the information identified in section

4. (6) of this rule, Recordkeeping Requirements.

   1. (D) Control (including the terms “controlling,” “controlled by,” and “common control”) means the possession, directly or indirectly, of the power to direct or to cause the direction of the management or policies of an entity, whether such power is exercised through one (1) or more intermediary entities, or alone, or in conjunction with, or pursuant to an agreement with one (1) or more other entities, whether such power is exercised through a majority or minority ownership or voting of securities, common directors, officers or stockholders, voting trusts, holding trusts, affiliates, contract, or any other direct or indirect means. The commission shall presume that the beneficial ownership of ten percent (10%) or more of voting securities or partnership interest of an entity constitutes control for purposes of this rule. This provision, however, shall not be construed to prohibit a covered utility from rebutting the presumption that its ownership interest in an entity confers control.
   2. (E) Corporate support means those functions dedicated to supporting the joint operations of a covered utility and some or all of its affiliates, including but not limited to the areas of corporate oversight, governance, support systems and personnel, payroll, shareholder services, financial services, financial planning and management support, human resources, employee records, pension management, legal services, research and development, information technology, accounting services, environmental services, internal audit, supply chain, regulatory affairs, facilities management, security, and community relations.
   3. (F) Cost allocation manual (CAM) means the document that specifies the criteria, guidelines, and procedures that the covered utility will follow to be in compliance with this rule. The CAM sets forth the covered utility’s cost allocation, market valuation, and internal cost methods.
   4. (G) Covered utility means, for purposes of this rule, an electrical corporation, gas corporation, or heating company as defined in section 386.020, RSMo, subject to commission regulation pursuant to Chapters 386 and 393, RSMo, or a water corporation as defined in section 386.020, RSMo, subject to commission regulation pursuant to Chapters 386 and 393, RSMo, with more than eight thousand (8,000) customers, or a sewer corporation as defined in section 386.020, RSMo, subject to commission regulation pursuant to Chapters 386 and 393, RSMo, with more than eight thousand (8,000) customers.
   5. (H) Derivatives means a financial instrument with a value, realized or unrealized, that is directly dependent upon or derived from an underlying factor. This underlying factor can be financial assets, real assets, indices, securities, debt instruments, commodities, other derivative instruments, any agreed upon pricing index or arrangement (e.g., the movement over time of the Consumer Price Index or freight rates), or the composition of these factors. Derivatives can involve the trading of rights or obligations based on the underlying good, but may not directly transfer property. They are used to hedge risk or to exchange a floating rate of return for a fixed rate of return or vice versa.

   6. (I) Financial advantage means an advantage provided by a covered utility to an affiliate when the covered utility—

      1. 1. Compensates an affiliate for assets, goods, information,

or services of any kind above the lesser of—

1. A. The fair market price (FMP); or
2. B. The fully distributed cost (FDC) to the covered utility

to provide the assets, goods, information, or services for itself; or

1. 2. Transfers assets, goods, information, or services of any

kind to an affiliate below the greater of—

1. A. The FMP; or
2. B. The FDC to the covered utility.
3. (J) Fair market price (FMP) means a price determined by a covered utility as the amount it would pay or receive for receiving or providing a good or service in an affiliate transaction based on comparisons of similar transactions with, or the price of similar goods and services available from, unrelated third parties. A covered utility shall make such determination based on competitive bids, if feasible. If not feasible, surveys, third-party studies, specific price inquiries, benchmarking, or any other reasonable method may be employed for this purpose. For goods or services for which there is no readily available comparative market price, the price shall be the fully distributed cost of the entity supplying the goods or services. The covered utility shall have the burden of demonstrating its method of determining FMP is reasonable, and/or that there is no readily available comparative market price for a given good or service.
4. (K) Fully distributed cost (FDC) means a methodology that examines all costs of an enterprise in relation to all the goods and services that are produced. FDC requires recognition of all costs incurred directly or indirectly to produce a good or service. Costs are assigned either through a direct or allocated approach. Costs that cannot be directly or indirectly charged or assigned (e.g., general and administrative) must also be included in the FDC calculation through a general allocation.
5. (L) Information means any data obtained by a covered utility that is not obtainable by nonaffiliated entities or can only be obtained at a competitively prohibitive cost in either time or resources.
6. (M) Marketing affiliate means an affiliate that engages in or arranges a commission-related sale of any natural gas service or portion of natural gas service to a shipper.

8. (O) Opportunity sales means sales of unused contract entitlements necessarily held by a gas corporation to meet the daily and seasonal swings of its system customers and intended to maximize utilization of assets that remain under regulation.

11. (R) Transportation means the receipt of natural gas at one point on a covered gas utility’s system and the redelivery of an equivalent volume of natural gas to the retail customer of the gas at another point on the covered gas utility’s system including, without limitation, scheduling, balancing, peaking, storage, and exchange to the extent such services are provided pursuant to the covered gas utility’s commission tariff, and includes opportunity sales.
12. (S) Variance means an exemption granted by the commission from any applicable standard required pursuant to this rule. Any variances granted to 20 CSR 4240-40.015 shall continue as a variance under this rule.

1. (2) Standards.

   1. (A) A covered utility shall not provide a financial advantage to an affiliate.
   2. (B) A covered utility shall conduct its business in such a way as to not provide any preferential position to an affiliate over another entity at any time.
   3. (C) A covered utility shall not participate in any affiliate transactions that are not in compliance with this rule, except as otherwise provided in the variance section (11) of this rule.
   4. (D) If a customer requests information from the covered utility about goods or services provided by an affiliate, the covered utility may provide information about the affiliate but must inform the customer that regulated services are not tied to the use of an affiliate provider and that other service providers may be available. The covered utility may provide reference to other service providers or to commercial listings, but is not required to do so.
   5. (E) All forms of marketing materials, information, or advertisements, including but not limited to those in electronic or digital form, distributed to a covered utility’s customers by an affiliate entity that shares an exact or similar name, logo, or trademark of the covered utility shall clearly display in a font size no smaller than ten- (10-) point font or announce that the affiliate entity is not regulated by the “Missouri Public Service Commission.”

   6. (F) This section shall not apply to or prohibit any of the following unless found by the commission, after notice and hearing, that such practice is contrary to the purposes and intent of this rule:

      1. 1. The joint provision of corporate support services, at

FDC, between or among a covered utility and any affiliate. This includes joint provision of corporate support services by an affiliated service company; and

1. 2. The provision, at FDC, of goods, information, or services

of any kind between or among a covered utility and an affiliate regulated by the commission or other state utility commission, provided that a covered utility may share information with such an affiliate as part of its day-to-day communications with such an affiliate for the process of improving service, operations, or efficiency.

   8. (H) A covered gas utility shall not condition or tie an offer or agreement to provide a transportation discount to a shipper to any service in which the marketing affiliate is involved.

      1. 1. File an application in the commission’s electronic filing

1. (I) A covered gas utility shall not make opportunity sales directly to a customer of its marketing affiliate or to its marketing affiliate unless such supplies and/or capacity are made available to other similarly situated customers using nonaffiliated marketers on an identical basis given the nature of the transactions.
2. (J) A covered gas utility shall not condition or tie agreements (including prearranged capacity release) for the release of interstate or intrastate pipeline capacity to any service in which the marketing affiliate is involved under terms not offered to nonaffiliated companies and their customers.

If the complaint has not been recorded by the covered gas utility within three (3) days, an explanation for the delay must be recorded.
6. (N) A covered gas utility will not communicate to any customer, supplier, or third parties that any advantage may accrue to such customer, supplier, or third party in the use of the regulated gas corporation's services as a result of that customer, supplier, or third party dealing with its marketing affiliate and shall refrain from giving any appearance that it speaks on behalf of its affiliate.
7. (O) If a customer requests information about a marketing affiliate, the covered gas utility may provide the requested information but shall also provide a list of all marketers operating on its system.

   1. (A) When a covered utility purchases information, assets, goods, or services from an affiliate, other than those listed in subsection (2)(F) of this rule, the covered utility shall either determine a FMP for such information, assets, goods, or services or demonstrate why no reasonable FMP can be determined.
