ANATOMY OF THE PROCEEDINGS

T2 Southwestern Bell Telephone, L.P. d/b/a SBC Oklahoma ("SBC" or "SBC Oklahoma") is an Incumbent Local Exchange Company (ILEC) that provides telecommunications services in Oklahoma. It is regulated by the Oklahoma Corporation Commission (the "Commission) under an alternative regulatory scheme called the Oklahoma Plan. The Oklahoma Plan gives SBC the ability to seek some measure of freedom from regulatory oversight by the Commission depending on the level of competition present in the Oklahoma telecommunications marketplace. One of its provisions, OAC 165:55-5-66(4), permits a regulated telecommunications service to be reclassified as competitive if the Commission determines that the service is subject to effective competition and that functionally equivalent and substitute services are available. If found to be competitive, a service is placed into what is figuratively called Basket 4. Price changes of Basket 4 services go into effect immediately and without first having to receive the Commission's approval. SBC applied to the Commission on 21 January 2005 for a competitive reclassification of most of its intrastate retail - telecommunications - services. Cox Oklahoma Telecom, LLC ("Cox") and AARP Oklahoma ("AARP") intervened to oppose SBC's application.

T3 After receiving prefiled, written testimony from numerous witnesses for each party, the Commission in June 2005 held a two-day hearing on SBC's application. With one commissioner dissenting, the Commission issued its Final Order (the "Order") on 28 July 2005, reclassifying as competitive all but three of SBC's intrastate retail telecommunications services. The Commission also decided a number of collateral issues. The Order did not alter any of SBC's existing intrastate retail rates nor did it affect any of SBC's wholesale services or rates.

1 4 Cox appealed from the Order in Cause No. 102,392; AARP filed an appeal in Cause No. 102,461. The separate appeals were consolidated on 14 September 2005 under surviving Cause No. 102,392, which was retained for this court's disposition by a single opinion.

II

STANDING TO APPEAL

15 SBC and the Commission ("appellees") seek dismissal of Cox's appeal for lack of standing. Standing refers to a person's legal right to seek relief in a judicial forum. It is a threshold question that must be decided before any other issue may be addressed. Standing to appeal from an order of the Commission is governed by Article 9, Section 20 of the Oklahoma Constitution, which provides that an appeal may be taken by "any party affected" or "any person deeming himself aggrieved" by an action of the Commission affecting the rates, charges, services, practices, rules or regulations of a public service corporation. The purpose of the standing requirement is to ensure that courts address actual controversies between parties who bave sufficient adverse interests. The standing doctrine should never be applied mechanistically to bar from the courthouse those who are truly aggrieved.

T6 Appellees argue that Cox does not have standing to press for corrective relief in this cause because nothing in the Order directly harms Cox's pecuniary interest. We are told by appellees that Cox cannot be injured by the Order because the Order authorizes only legitimate competition in the Oklahoma telecommunications market. According to appellees, the injury Cox fears-anti-competitive or predatory behavior by SBC-is speculative and contingent on future events. It assumes not that injury will result from SBC's adherence to the Order but rather that it will result from conduct that violates the Order. Cox argues in response that the Order causes it injury because it unlawfully lifts regulatory oversight of SBC, the effect of which will be increased competition from SBC that will directly, immediately, and substantially harm Cox's pecuniary interest.

17 We are persuaded that Cox is a proper party to seek corrective relief from the Commission's Order. We have on several occasions held that a person is aggrieved by competition resulting from an unlawful action of a government agency. Competitive harm or the threat of competitive harm from the lifting of regulatory oversight has also been held to be a sufficiently concrete injury to confer standing by the Court of Appeals for the District of Columbia Circuit, which has been faced many times with appellate complaints of injurious actions by federal agencies.

' 8 The Order constitutes a departure from the manner in which SBC has been regulated under the Oklahoma Plan. It would give SBC a high degree of pricing freedom based upon the Commission's finding that a new day has dawned in the telecommunications industry in this state-a day in which SBC faces sufficient competition to constrain it from engaging in anti-competitive or predatory pricing. Cox vehemently disagrees with this finding. It argues that competitors in Oklahoma have barely even begun to challenge SBC's market hegemony, making the pricing freedom granted to SBC by the Order premature and a threat to the economic viability of SBC's competitors. We declare this potential for economic harm that results from a diminution in regulatory oversight by the Commission gives Cox standing to press for relief in this appeal.

III

STANDARD OF REVIEW

T9 The power to review Commission decisions is vested in this court by the Oklahoma Constitution, Art. 9 § 20. That provision fashions two standards of review-a de novo standard for appeals based on alleged violations of constitutional rights and a more deferential standard for all other appeals. Today's pronouncement employs both standards. Because Commission decisions often involve complex issues of economics, accounting, engineering, and other special fields of knowledge, a presumption of correctness accompanies the Commission's findings in matters it frequently adjudicates and in which it possesses expertise.

IV

THE COMMISSION CORRECTLY TREATED THIS PROCEEDING AS LEGISLATIVE IN NATURE

T 10 The Commission ruled that SBC's application should be treated as a legislative matter. Appellants argue that this decision constitutes reversible error. Initially, we note that neither Cox nor AARP ("appellants") objected below to treating this proceeding as legislative. This omission would ordinarily preclude our review of appellants' contention, but the rule has an exception that permits review of an alleged deprivation of due process of law despite failure to preserve it below. While appellants do not use the term due process to describe their attack, they claim that the Commission's decision to treat this proceeding as legislative rather than judicial resulted in a hearing that was fundamentally unfair. The flaws alleged to inhere in the hearing include lobbying, ex parte contacts, and a failure of the Commission to follow its own rules. The gist of these allegations is that the legislative designation of this proceeding led to a violation of appellants' right to receive the benefit of due process. We will therefore consider this proposition of error despite appellants' failure to object below.

11 Both appellants and appellees rely on the landmark decision by the United States Supreme Court in Prentis v. Atlantic Coast Line Company, which defined a judicial inquiry as one which "investigates, declares, and enforces liabilities as they stand on present and past facts and under laws supposed already to exist" and defined a legislative proceeding as one that "looks to the future and changes existing conditions by making a new rule to be applied thereafter." This court has adopted Prentis's classic definition of legislative and judicial proceedings and has held that the kind of process that is a litigant's due flows from the label attached by law to a proceeding.

1 12 Appellants argue that SBC's application exhibits the essential characteristics of a judicial proceeding as defined by Prentis. They contend that the Commission examined present and past facts regarding the extent of competition in the Oklahoma telecommunications market, applied existing Commission rules to those facts, and decided, after vigorous contest, that SBC's services were subject to effective competition and entitled to be placed in Basket 4.

13 Appellees argue that SBC's application displays the typical qualities of a legislative proceeding as defined by Prentis The question of competition among telecommunications service providers calls for a policy assessment that will determine how SBC's rates will be set in the future. It is hence similar, although not identical, to a rate hearing. Appellees also argue that in ruling on the competitiveness of the Oklahoma telecommunications market, the Commission is not exercising its dispute-settling function by declaring and enforcing liabilities as it would in judicature, but is instead establishing a rule for the future, equally applicable to all telecommunications service providers.

114 The line between what is legislative and what is judicial is not always a clear one, but we agree with the Commission that this proceeding is more akin to legislation than to adjudication. We see the Commission's role in this cause as similar to that of a legislative committee engaged in fact-finding for the purpose of legislation. The Commission was not charged with arriving at a strictly accurate reconstruction of past events in order to settle a private dispute between the parties, but rather with establishing a rule to guide it in making decisions about the telecommunications industry in the future. The Commission's inquiry required it to hear testimony and argument from contending factions and witnesses, but the fact that there was conflicting evidence and parties standing in opposition to the relief requested does not make the proceeding judicial. Proposed legislation often engenders heated contest between those who favor it and those who oppose it.

1 15 We also conclude that while this was not a ratemaking proceeding per se. it was closely related to ratemaking. The rule it establishes will permit SBC to determine its own rates in the future with only minimal regulatory supervision. - Ratemaking has been definitively labeled and treated as legislative.

T16 Despite the legislative characterization the Commission gave to this proceeding, we note that the parties were afforded many of the due process protections associated with a judicial proceeding, including notice and opportunity to be heard, the right to present their own witnesses, and the right to cross examine opposing witnesses. As for the allegations of improper communications, legislative proceedings are not governed by judicial standards of communication among decision-makers or between decision-makers and others.

V

THE COMMISSIONS REFUSAL TO DISMISS SBC'S APPLICATION AS PREMATURELY FILED WAS NOT CONTRARY TO LAW

T17 An ILEC which is regulated under the Oklahoma Plan must wait until the expiration of five years from the date it opted to be regulated under the Oklahoma Plan to petition for a competitive reclassification. The rule applies to two types of services: basic local residential service and local operator services. SBC's application sought reclassification of services subject to the five-year rule as well as services not subject to that rule. The application was filed on 21 January 2005. Because SBC opted to be regulated under the Oklahoma Plan on 12 June 2000, appellants argued before the Commission that the application, insofar as it requested reclassification of services subject to the five-year rule, was approximately six months premature and should be dismissed. The Commission agreed that the application was premature, but granted SBC's motion for a waiver of the five-year waiting period. Appellants now argue that the Commission erred in granting the waiver.

18 The Commission eannot arbitrarily ignore its duly-promulgated procedural rules, but it is expressly authorized by the Oklahoma Administrative Code to waive its rules under certain cireumstances. The pertinent rule states:

"Whenever compliance with any requirement of this Chapter [Chapter 55-Tele-communications Services] would result in unreasonable hardship upon or excessive expense to the telecommunications service provider, IXC or the end-user, or for other good cause shown, the Commission may, by order, waive or modify the requirements of this Chapter upon application of any interested person. The Commission may grant temporary relief pending hearing.

The court has declared that in applying this rule, the vice to be avoided is the arbitrary or capricious exercise of power and, to that end, has imposed on the Commission an obligation to give a reasoned explanation when it chooses to waive a rule.

€ 19 The Commission provided the following explanation for waiving the five-year rule in this cause:

"[IHt is in the public interest to waive OAC 165:55-5-66(1)(A)@M). SBC has already met the time requirement for requesting changes to the rates for business services and although the Five Year Period will not expire regarding the residential service until June 15, 2005, judicial economy would be best served by hearing the testimony regarding business rates and residential rates in the same hearing. Therefore, the Commission finds there is good cause to waive OAC 165:55-5-66(1)(A)(i1)."

%20 Appellants argue that this statement is insufficient to justify the waiver. We disagree. The Commission found that the preservation of judicial resources constitutes good cause to waive the rule. Good cause means a fair and honest reason, one which is not trivial, arbitrary, capricious, or concocted for the occasion. Only if the reason provided is so irrational as to render the decision arbitrary and capricious should it be reversed. We believe the Commission has provided a rational and defensible basis for granting the waiver. Because the five-year rule applies to only two categories of services and because the evidence would essentially be the same for all services, the Commission concluded that strict adherence to the rule would entail multiple proceedings resulting in a waste of judicial resources. While the Commission could have avoided multiple hearings in other ways, its choice to waive the requirement was not arbitrary or capricious. We note that the hearing on the application in this cause did not take place until after the expiration of the five-year moratorium. Appellants therefore had the opportunity to inform the Commission of any changes in the competitive landscape of the telecommunications industry in Oklahoma up to the date of the hearing.

VI

THE COMMISSION DID NOT ERR IN PLACING SBC'S RECLASSIFIED SERVICES INTO BASKET 4 AT THEIR EXISTING PRICES

4 21 Appellants argue that the Commission erred in placing SBC's services into Basket 4 at their existing tariff prices. Appellants point out that the provisions of OAC 165:55-5-66(4)(B) state that the price of a service in Basket 4 will equal or exeeed the service provider's long-run incremental cost (LRIC) of providing the service or will be arrived at by applying imputation where appropriate. The Commission ruled that this provision does not impose LRIC pricing as a precondition to Basket 4 placement, but instead permits services to be placed in Basket 4 at a price other than LRIC and reserves to the Commission the power to review those prices in the future for compliance with the LRIC price standard. Accordingly, the Commission ruled that evidence of the LRIC of the services for which relief was requested was not required at this proceeding and placed SBC's services into Basket 4 at the lower of their tariffed price as of the date of the Order or their LRIC.

T22 Appellants argue on appeal that the Commission violated its own pricing rule, which they say mandates LRIC or imputed pricing before services can be placed into Basket 4. In order to comply with this rule, appellants contend, the Commission had to obtain from SBC LRIC cost studies of the services under consideration for reclassification, but contrary to the clear import of the rule, the Commission wrongly decided that LRIC cost studies were not necessary. Instead, the Order places services into Basket 4 without any evidence of their LRIC and at prices which, appellants assert, are in all likelihood less than LRIC. Anticipating that appellees might claim the Commission waived the rule, appellants argue that any attempt to claim the rule was waived must fail inasmuch as the Commission did not announce a decision to waive the rule nor provide a reasoned explanation for waiving it.

123 This court will show great deference to an agency's interpretation of its own rules. When the terms of a regulation

are amenable to more than one meaning, we ordinarily defer to the interpretation adopted by those charged with the duty of administration. When choosing between two or more possible meanings of a regulation, controlling weight may be given to long-continued administrative usage unless it is plainly erroneous or inconsistent with the language. Deference to an agency's interpretation is even more clearly in order when the construction is that of an administrative regulation rather than a statute.

124 The Commission's interpretation of OAC 165:55-5-66(4)(B) is not plainly erroneous or inconsistent with the rule's language. Subsection A of the rule states that services which meet certain criteria will be placed in Basket 4. To read Subsection B as appellants suggest would impose an additional requirement for reclassification that would interfere with the operation of the mandatory language of Subsection A. It is hence reasonable to interpret OAC 165:55-5-66(4) as setting up a multi-stage process that permits reclassified services to be placed into Basket 4 at a price other than LRIC with serutiny for compliance with the price floor to follow, if necessary.

125 The Commission's decision to utilize the existing tariff prices of SBC's services as an initial price floor for Basket 4 services is consistent with the general intent of Section 66(4)(B), which is to prevent anti-competitive or predatory pricing. There appears to be general agreement among the parties to this proceeding that the existing tariff prices of SBC's services were set many years ago and have ever since been determined by the Commission to be just and reasonable. No one, including appellants, has suggested that the existing prices of SBC's services are predatory or anti-competitive. If the Commission were compelled to price SBC's services at LRIC as a prerequisite to reclassification, it would almost certainly mean that rates would increase. It is unlikely the Commission intended a rule meant to benefit the public through increased competition to automatically result in a price increase in the absence of some indication that the current prices are anti-competitive.

T 26 The Commission's decision is also supported by the fact that the introductory sentence to OAC 165:55-5-66 authorizes services to be priced at their existing tariff prices upon a provider's election to be regulated under the Oklahoma Plan. The price floor for Basket 3 is the LRIC of the service plus 20%; the price floor for Basket 4 is the LRIC of the service. Nothing in this record tells us whether any services were placed into these baskets when SBC opted to be regulated under the Oklahoma Plan, but the introductory sentence of the rule clearly authorizes the use of existing tariff prices upon implementation of the Oklahoma Plan despite the LRIC-related price floors for Basket 3 and Basket 4 services specified in the rules.

127 Finally, LRIC cost studies have apparently not been required in previous proceedings for Basket 4 reclassification. The Commission's refusal to require cost studies in this proceeding thus appears to be consistent with its treatment of this issue in other similar proceedings.

VII

THE COMMISSION DID NOT ERR IN ADMITTING INTO EVIDENCE TESTIMONY BASED ON THE EQ911 DATABASE AND TWO SURVEYS OF TELEPHONE SERVICE CUSTOMERS

"I 28 Appellants unsuccessfully objected below to the admission of testimony based on the EQ11 database, a collection of telephone numbers administered by SBC which is maintained to enable emergency services to be dispatched to a specific location associated with a particular telephone number. SBC offered the testimony to show the number of access lines attributable to facilities-based landline competitors. Cox argues that the database overstates the number of facilities-based wireline access lines and should have been excluded as unreliable.

29 Appellants also objected unsuccessfully to the admission of two surveys conducted on behalf of SBC which consist of interviews of wireless and wireline subscribers and to the testimony given in connection with those surveys. The surveys were offered by SBC to prove that it faces competition not only from other wireline service providers, but also from wireless telephone service and VoIP (Voice over Internet Protocol), a broadband-based telephony product.

€ 30 Under the Oklahoma Evidence Code, the trial tribunal stands as a "gatekeeper," admitting or excluding evidence based on the hearing officer's assessment of its relevance and reliability. All relevant evidence is admissible, unless the trial tribunal determines that "its probative value is substantially outweighed by the danger of unfair prejudice, confusion of issues, misleading the jury, undue delay, needless presentation of cumulative evidence, or unfair and harmful surprise." A trial tribunal has discretion in deciding whether proffered evidence is relevant and, if so, whether it should be admitted, and a judgment or order will not be reversed based on a hearing officer's ruling to admit or exclude evidence absent a clear abuse of discretion.

131 Notwithstanding appellants' eri-tique of the reliability of the EQ11 database, substantial evidence is present in the record from which the Commission could have concluded that the EQ11 database provides a reasonable estimate of facilities-based land-line competition. No abuse of discretion hence attended the Commission's decision to admit into evidence testimony derived from the database.

132 Cox has also failed to demonstrate that the Commission abused its discretion in admitting the surveys. At the outset, we note that the surveys were admitted into evidence without objection from Cox or AARP at the pre-hearing conference held on 13 June 2005. It was not until the first day of testimony that Cox began to object to their admission, challenging them on the grounds of hearsay and lack of proper foundation. The objection was summarily overruled without the benefit of argument. The next day, Cox filed a written motion to exclude the surveys with brief attached. The Commission never ruled on the written motion. Cox included both the hearsay and proper foundation arguments in its list of issues to be argued on appeal, but mentioned lack of proper foundation and qauthentication as objections only in a terse footnote in its brief-in-chief. After SBC and the Commission filed their answer briefs, in which neither reacted to Cox's footnote, Cox filed a reply brief in which it briefly argued sans authority that the surveys should be deemed inadmissible for lack of authentication.

T 33 The court has on many occasions said that judicial review will not be given to issues that receive only superficial treatment in an appellate brief or to assignments of error that lack a reasoned argument or supporting authority. The footnote in Cox's brief-in-chief does no more than mention in passing appellants' objections to the surveys. It clearly falls short of meriting judicial attention. Cox's attempt in its reply brief to raise the issue of authentication must also be rejected as too little too late. New arguments may not be raised for the first time in a reply brief. Cox's attempt to incorporate by reference its earlier motion to exclude the surveys and brief in support, filed below, must also be rejected. Not only does it violate the rule against presenting new arguments in a reply brief, but it also conflicts with Oklahoma Supreme Court Rule 1.11(f), which sets out the requirements for the statement and support of propositions in appellate briefs. It clearly states that the contentions of the parties "must be set forth in separate propositions" and "[the argument and authorities in support of each proposition must follow the statement of the proposition." Appellants bear the burden of showing that the admission of the surveys was an abuse of the Commission's discretion. They have failed to do so and we will not reverse the Commission's evidentiary ruling absent adequate reason.

VIH

EVIDENTIARY ISSUES

1 34 Two provisions of the Oklahoma Plan govern the competitive reclassification of telecommunications services. The provisions of OAC 165:55-5-66(4) ("Section 66(4)") cereate the category of competitive services, identify the standard for measuring competition, and set the pricing and tariffing consequences of Basket 4 placement. That provision states:

Basket 4-Competitive Services.
[10] (A) Services which are competitive, pursuant to OAC 165:55-5-10.1, and for which functionally equivalent and substitute services are available will be placed in Basket 4.
(B) The price floor for all services in this Basket will be the greater of the LRIC of the service under consideration or a price which is arrived at by applying imputation where appropriate.
(C) Price revisions to the tariffs for services in Basket 4 shall become effective on the date specified on the revised tariff sheets after the provider has delivered 3 copies of the revised tariff sheets to the Director of the Public Utility Division. The effective date shall be no earlier than the date the revised tariff pages are delivered.

135 The second provision is OAC 165:55-5-10.1 ("Section 10.1"), the section of the Oklahoma Administrative Code incorporated by reference into Subsection A of Section 66(4), as set out above. It contains a five-part, non-exclusive assessment for determining whether a regulated telecommunications service is "subject to effective competition." Section 10.1 states:

Competitive services
(a) A telecommunications service provider may file an application to have the Commission determine that a regulated telecommunications service, other than local directory assistance or operator services is subject to effective competition and is therefore competitive for the applicant and/or the applicant class.
(b) In determining whether a service is competitive, factors the Commission will consider include, but are not limited to:
(1) The number and size of alternative providers of comparable services;
(2) The extent to which comparable services are available from alternative providers in the relevant market;
(3) The ability of alternative providers to make functionally equivalent or substitute services readily available at competitive rates and terms and conditions;
(4) Public interest considerations; and,
(5) Other indicators of market power with respect to a service, which may include market share, growth in market share and whether the alternative provider(s) of comparable services are affiliated with the telecommunications service provider.
(c) In considering these and other factors, the Commission is not required to give equal weight to each factor in subsection
(b) of this Section, but has discretion to give more weight to a particular factor or factors, based on the evidence.

T36 The Commission received a voluminous amount of conflicting evidence related to the factors set out in these two rules and made a host of factual findings based upon the evidence presented. Appellants challenge most of these findings as unsupported by substantial evidence. The term "substantial evidence" means "more than a mere scintilla" but a quantum that may be less than the weight of the evidence. It is proof that possesses something of real and relevant consequence and that carries with it a fitness to induce conviction. In testing evidence for substantiality, a reviewing court must consider not only the evidence supporting the decision, but also the evidence which detracts from it. The court has held that searching a record for substantial evidence that supports an order does not entail a comparison of the parties' evidence to determine that which is most convineing. Instead, if the evidence supporting an order possesses a quality of proof inducing a conviction that the evidence furnished a substantial basis of facts from which the issue could be reasonably resolved, it is sufficient. In cases before the Commission involving the testimony of expert witnesses, a factual finding is supported by substantial evidence when the evidence is offered by a qualified expert who has a rational basis for his/her views, even if other experts disagree. It is for the Commission, not the court, to weigh conflicting expert testimony.

137 Appellants also attack several of the Commission's findings for lack of adequate content. We have said that the Commission's rulings must have content sufficient to permit a reviewing court to determine whether there was substantial evidence in support of a decision. This is not a requirement that the Commission recite in its orders all the evidence in support of its decision or that it address every item of evidence supporting a contrary decision. Commission rules require that body to provide, inter alia, a summary of the evidence adduced by all parties of record, findings of fact, containing all ultimate facts found to have been established, and conclusions of law, containing all applicable legal conclusions and a concise statement of what the order mandates. An order substantially conforming to this rule cannot be assailed for lack of adequate content.

A. Relevant Product Market

138 Sections 10.1 and 66(4) use a variety of terms to describe the services that must be available from competing providers to justify a finding of effective competition. These include "functionally equivalent services," "substitute services," and "comparable services." All such terms relate to the concept of product market. The Commission found that the important determinant of whether two services are in the same product market is their "reasonable interchangeability of use." It also found that services do not have to be identical to be in the same product market.

139 Cox argues without citation to authority that the standard should be whether a service is "truly interchangeable," not just reasonably interchangeable. We disagree. There is abundant authority defining the concept of relevant product market as the pool of goods or services that enjoy reasonable interchangeability of use. We hold that the Commission did not err in using reasonable interchangeability of use as the standard for determining the relevant product market.

B. Competition from CLEC, Wireless, and VoIP Providers

- 40 The Commission found that SBC faces effective competition when the services offered by CLEC, wireless, and VoIP providers are considered in the aggregate. Appellants contend that the evidence shows quite the opposite.

141 First, appellants argue that wireless and VoIP are not interchangeable with wire-line telephony and should not even be taken into account in evaluating competition among telecommunications providers in Oklahoma. They point to testimony that the quality of service provided by wireless and VoIP is inferior to the quality of service provided by landline phones, making the former poor substitutes for the latter. They also refer us to testimony that only a very small percentage of wireless subscribers have actually "cut the cord" on wireline service and that the percentage of VoIP substitution for wireline is negligible. This actual level of substitution, they contend, reflects public recognition that the services are not interchangeable and is a far more reliable indicator of public perception than opinion surveys. Witnesses appearing on behalf of the Commission Staff agreed with appellants that wireless and VoIP are not substitutes for landline phone service.

42 SBC presented evidence that wireless and VoIP should be considered in the same product market as wireline phones and that they are in fact competing successfully with SBC's intrastate retail services. SBC's expert witness testified that it is not necessary for services to be identical to be fit substitutes. We are told by SBC that wireless service is functionally equivalent to and a substitute for basic local exchange service because both modes of service enable users to make and receive calls in their homes and businesses. The witness testified that there are numerous providers of wireless service in Oklahoma and that thirteen wireless companies, many of which are large, national firms, have executed and filed interconnection agreements with SBC. SBC presented testimony that three wireless providers have been granted ETC ("Eligible Telecommunications Carrier") status by the Commission and must meet the same minimum service standards as wireline carriers. Furthermore, an SBC witness testified that all wireless providers have been ordered by the FCC to make enhanced 911 service available. SBC presented evidence that as of June 2004 the number of wireless subscribers in Oklahoma exceeded the total number of access lines attributable to SBC and certain other reporting independent Oklahoma telephone companies. SBC offered testimony about research findings indicating that the substitution of wireless for wireline phone service is increasing. With respect to usage substitution, an SBC witness testified that the percentage of all voice minutes being carried by wireless had tripled in the preceding three years. According to this expert, the more usage migrates to wireless networks, the more likely people will simply transfer their remaining usage to wireless. Finally, SBC presented two surveys, one of wireless subscribers and one of wireline customers, inquiring into the interviewees' usage of and attitudes toward various modes of telecommunications services. According to SBC's witness, these surveys show that the public increasingly views wireless service as an alternative to landline phones.

148 An SBC witness also testified that VoIP can be considered a substitute for land-line service even though it does not provide identical features and technology. His surveys indicate that the public is aware of IP technology, a fraction have actually used VoIP at one time or another, and a healthy percentage of both wireless and wireline users have considered using VoIP. He testified that businesses are beginning to see certain advantages to using VoIP and that some have switched to it already. As with wireless, VoIP providers have been ordered by the FCC to provide access to enhanced 911 services.

1 44 In response to appellants' contention that actual substitution of wireless or VoIP for wireline service is rare, SBC's economics expert testified that if consumers perceive wireless and/or VoIP to be reasonable substitutes for wireline phones, that perception acts as a constraint on SBC's ability to raise prices on its services regardless of the extent to which wireless and VoIP are actually used as substitutes for wireline phones. This is so, says SBC's expert, because consumers can discontinue wireline service and migrate to wireless or VoIP service should wireline prices rise to an uncompetitive level.

145 We cannot recite here all of the evidence supporting and opposing the quality of substitutability of wireless and VoIP for wireline service. The question for us is whether there was substantial evidence to support the Commission's finding that wireless and VoIP are reasonably interchangeable for landline service. We think there was sufficient evidence presented to meet this standard. SBC's economics expert witness testified that the ultimate determinant of whether products are substitutes, one for the other, and compete with one another is whether they have the ability, actual or potential, to take significant amounts of business away from one another. The record evidence is sufficient to support the Commission's conclusion that wireless and VoIP have that ability.

46 The Commission also found that SBC faces effective competition from competitive local exchange carriers or CLECs. Cox points to the testimony it and AARP presented which is to the contrary, showing that SBC's share of the local exchange market is far greater than that of its largest CLEC competitor and that CLEC competition is likely to decline in the future due to regulatory changes and other cireumstances. SBC presented testimony that market share is not decisive and that CLEC competition is growing, a trend SBC insists is not likely to be reversed despite the regulatory changes cited by appellants. Presented with this conflicting evidence about CLEC competition, the Commission gauged the evidence which was proffered by SBC to be the more persuasive. The Commission heard the testimony and observed the witnesses first-hand. We will not second guess the Commission's judgment as to the weight and credibility of the evidence unless the weight of the evidence clearly supports a contrary conclusion. In this case, it does not and the Commission's determination must stand.

147 With respect to the Commission's overall finding that CLECs, wireless and VoIP provide effective competition for SBC's services, it is important to keep in mind that the Commission did not pin its decision on a single competitive source, but rather found effective competition from a combination of other landline providers and intermodal competitors. To the extent that CLEC competition may not be as robust as SBC portrayed it, the Commission's decision to consider wireless and VoIP in the same product market as wireline service serves to compensate for a lower level of CLEC competition.

C. - Statewide Competition

« 48 Appellants argue that there is no evidence to support the Commission's finding that there is competition statewide that provides a competitive constraint on SBC's pricing. The evidence clearly shows that the extent of CLEC competition is greater in urban and suburban areas than it is in rural areas of Oklahoma and that wireless and VoIP substitution is limited. Here again, it is important to view the evidence as the Commission did in light of the theory of competition advanced by SBC's economics expert. The question is not the extent of actual displacement of SBC's services by a competitor, but whether there are alternatives available statewide that provide a competitive constraint on SBC's pricing. The evidence supports the Commission's finding that, viewed in the aggregate, CLEC, wireless, and VoIP providers are available statewide and their presence, regardless of current market share or strict identity of service quality, serves to constrain SBC's pricing.

D. Market Power and Market Share

[ 49 One of the factors set forth in Section 10.1 for the Commission to consider is market power. The pertinent provision states:

(b) In determining whether a service is competitive, factors the Commission will consider include, but are not limited to:
Cole A Ae Ae
(5) Other indicators of market power with respect to a service, which may include market share, growth in market share and whether the alternative provider(s) of comparable services are affiliated with the telecommunications service provider.

Appellants argue that the Commission wholly failed to take this factor into account. We disagree. The wording of this provision-"other indicators of market power"-carries with it the grammatical implication that one or more of the preceding four factors are also indicators of market power. That implication is borne out by the first three factors set out in Section 10.1, which are all features relevant to a market power analysis. While the Commission might have tracked the language in OAC 165:55-5-10.1 more closely, it is readily apparent upon reading the Order that the Commission made findings related to these factors. Additionally, the Commission's finding regarding affiliated providers of comparable services is specifically listed in Section 10.1 as a market power factor. We hence reject appellants' contention that the Commission's Order ignores market power.

150 Appellants also argue that the absence from the Order of any findings regarding market share constitutes a failure by the Commission to comply with the provisions of Section 10.1. We disagree. Section 10.1 does not require the Commission to consider market share. The rule treats market share as one of the "other" possible indicators of market power which the Commission may, but does not have to, address. The record provides a rationale for this omission. SBC's expert witness, an economist, testified at length as to the shortcomings of market share as a reliable indicator of market power. She testified that entry barriers are far more important than market share and said that market share is essentially irrelevant where there are no significant barriers to entry. She then proceeded to testify about the lack of entry barriers in Oklahoma's telecommunications market. SBC's expert further testified that market share is a particularly misleading indicator of market power in an industry such as telecommunications that has been highly regulated and was recently characterized by monopoly. Although Cox and AARP presented evidence of SBC's large market share and AARP's expert witness testified that significant entry barriers continue to exist in Oklahoma's telecommunications market, the Commission chose to accept the evidence in support of SBC's position and treat market share as irrelevant. The record contains substantial evidence to support this decision.

E. Special Access Services

151 Appellants argue that there was no evidence presented to support the Commission's finding that special access service is faced with effective competition. We disagree. One of SBC's witnesses testified at considerable length about the various competitors who offer special access services in competition with SBC. While it is true that the witness testified only that other companies offer special access service, not as to how successful any of them are in gaining customers, the Commission could have treated this testimony in a manner consistent with the general principle, noted earlier, that actual competition and market share are not important in constraining prices so long as there are alternatives to which customers can turn should SBC raise its prices. We hold that the evidence was sufficient to support the Commission's finding.

F. Installation of DSL Technology inn Rural Central Offices

[ 52 In determining whether a telecommunications service is competitive and hence qualifies for Basket 4 pricing flexibility, Section 10.1 directs the Commission to consider and make findings related to the public interest. Among the public interest findings made by the Commission in this cause is that increased pricing flexibility would provide an incentive to SBC and to its competitors to invest in communications infrastructure in Oklahoma. In a related finding, the Commission concluded that it would be in the public interest to require SBC, as a condition of receiving relief, to install high-speed technology in a number of rural Oklahoma communities. Specifically, the Commission ordered SBC to take the following steps:

1. Upgrade its facilities by installing a DSLAM, or equivalent technology, in each of the 68 central offices served by SBC Oklahoma that are not currently equipped for the provision of DSL service....
2. Agree that when it completes the upgrade of a specific central office, it will ensure that all K-12 public schools and all hospitals within the serving area of that specific central office have access to DSL service or to broadband service, as defined in 17 0.8. 189.102(9), without restriction as to the specific technology used.
3. Make DSL service available to all customers within the technological service range of each rural DSLAM and not "red-line" any area within such technological service range.

Appellants contend that the Commission lacks jurisdiction (or authority) to impose these requirements on SBC and that the Commission's conclusion that the requirements are in the public interest is not supported by substantial evidence. While this appeal was pending, SBC filed a motion asking the court to treat both aspects of this issue as moot based on the fact that as of 28 November 2006 the company had completed all the DSLAM upgrades. We now declare that the issue is moot insofar as appellants contest the Commission's authority to impose the DSL requirements on SBC and to that extent we grant SBC's motion.

153 Cox and AARP also argue that there is no evidence in the record supporting the installation of DSLAMs as a public interest factor. We disagree. While no evidence was proffered specifically regarding DSLAM technology, SBC presented expert testimony that pricing flexibility would be in the public interest because it would lead SBC to invest in improved technology. AARP acknowledges in its brief that the encouragement of high-speed internet services is "a worthy goal," and that access to high-speed internet services is "critical to promoting academic achievement," and "a valuable tool which allows businesses to work more efficiently and to better compete in today's marketplace."

T 54 SBC's willingness to install DSL technology in rural areas in conjunction with receiving pricing and tariffing flexibility supports the Commission's finding that increased pricing flexibility will lead to improvements in infrastructure. - Requiring SBC to install improved technology in rural areas as a condition of receiving the relief requested was the Commission's way of demanding that SBC put its money where its mouth is, so to speak. Instead of waiting for market incentives to work, the Commission asked SBC to validate up front its experts' assertions about the positive relationship between pricing flexibility and improvements in infrastructure.

G. Risk-Benefit Finding

55 Appellants next challenge the eviden-tiary support for the Commission's public-interest finding that the potential benefits of reclassification outweigh the risks. The ree-ord contains a great deal of testimony supporting the Commission's finding. SBC's expert witness testified repeatedly about the benefits of competition in general and specifically about the benefits to be expected from granting SBC pricing flexibility. Cox points to the equivocal testimony of a Commission staff witness who said that granting SBC's application could be harmful to consumers and to competition. Substantial evidence supports the Commission's finding that the benefits of granting SBC's application outweigh the risks

H. Deregulation.

156 As discussed earlier in this opinion, the provisions of Section 66(4)(B) set LRIC as the price floor for competitive services. Because under the Order price revisions for SBC's reclassified services will become effective on the date they are delivered to the Director of the Public Utility Division, appellants argue that the Commission has no way to enforce the LRIC price floor, effectively deregulating SBC contrary to the public interest.

157 The Commission found that the effect of granting SBC's application was not to deregulate the company. We agree. The pricing freedom the Order grants is precisely what Section 66(4)(C) contemplates and authorizes. The Commission found that the interest of the public is nevertheless protected because the Commission "retains jurisdiction to correct any competitive market failure that might result ..." and because SBC remains "subject to the Commission's ability to enforce compliance with its rules." This is so in part because the rules permit the Commission to revoke the competitive designation of any service it determines is no longer competitive. The Commission's determination that the public interest is not threatened by giving SBC the ability to implement price revisions without prior regulatory supervision is a reasonable conclusion in light of the Commission's continuing ability to require price studies or revoke the competitive designation of any of SBC's services should it suspect anti-competitive behavior or predatory pricing.

I. Pricing

€58 Appellants next challenge the Commission's public interest finding regarding the pricing of SBC's reclassified services. We have already determined that the Commission correctly interpreted its rule to permit competitive reclassification of regulated telecommunications services without first requiring LRIC cost studies. Having so interpreted its rule, the Commission found that it would be in the public interest to place SBC's reclassified services into Basket 4 at the lower of the LRIC of the service or its existing tariff price. It came to this conclusion based on its finding that the prices of some services were set many years ago and were determined at that time to be just and reasonable. Implicitly finding that some, if not all, of the existing tariff prices are less than the LRIC of the services, the Commission found that it would not be in the public interest to require those prices to increase in order for the services to be placed in Basket 4. Appellants challenge this finding because setting rates below cost can have an anti-competitive effect.

"I 59 A price floor tied to the cost of supplying a service prevents a company from lowering prices below those which its competitors can meet and still remain in business. Once competitors have been eliminated, the surviving company's prices are no longer constrained by competition. Hence, below cost pricing is ordinarily not in the public interest in the long run even if in the short run the public is shielded from a price increase. That concern is obviated in this case because the Order reiterates the Commission's previous determinations that SBC's existing prices are just and reasonable. Having previously found that SBC's prices are neither anti-competitive nor predatory, the Commission's finding that it would not be in the public interest to raise those prices is justified.

J. Transitional Limitation on Price Increases in Rural Areas

60 The Commission found that it would be in the public interest to impose a five-year transitional limitation period on price increases for basic residential access line service within the rural areas served by SBC. This finding was based in part upon a related finding that rural ILECs in Oklahoma have had this type of pricing flexibility for many years and have not raised prices to an exorbitant level. The Commission also found that rural ILECs were investing in advanced communications services. Appellants argue that there was no evidence to support these findings. We disagree. SBC's economics expert testified as to the price of telephone service in rural areas and reported that rural ILECs were publicizing their investments in internet technology.

TI 61 Appellants also challenge the Commission's finding that if the existing price of a rural service is less than the service's LRIC, the Commission will not interfere with a price increase even if, as the Order provides, 15% of SBC's subscribers statewide ask the Commission to do so. Appellants assert that this is simply another example of the Commission evading its obligations under the LRIC price standard. We disagree. Not only is this provision not an attempt to evade the LRIC price standard, but its effect is to prevent the public from using the Commission to bloc the gradual adjustment of rural prices toward their LRIC.

K. Effect of LRIC Price Floor

T 62 The Commission found that the LRIC price floor applicable to Basket 4 services will prevent SBC from lowering prices to an anti-competitive level. Appellants argue that this finding is not supported by the evidence. As appellants correctly point out, there was no evidence whatsoever establishing the LRIC price floor for any of SBC's services. We must analyze this finding in light of the fact that the Commission knew it was placing SBC's services into Basket 4 at their existing prices, at least some of which are undoubtedly lower than their respective LRICs. We take the Commission's finding to mean no more than this: if SBC were to lower prices below the level at which they were placed into Basket 4, the Commission would have the authority to demand compliance with the LRIC price floor. Evidence of the current LRIC of SBC's services is not necessary in order to assert that the Commission has this authority.

IX

CONCLUSION

T63 In this appeal from an Order of the Commission that reclassifies all but three of SBC's intrastate retail telecommunications services as competitive and gives SBC pricing and tariffing flexibility, our review of the record in its entirety reveals no reason to reverse the Commission's decision. The Commission correctly decided to treat this proceeding as legislative in nature and its Order is supported by the law and substantial evidence.

KAUGER, J.,

with whom WATT, J. joins, concurring in part/dissenting in part:

T1 I do not agree that the proceeding at issue is "more akin to legislation than to adjudication." Nearly 100 years ago, the United States Supreme Court in Prentis v. Atlantic Coast Line Co., 211 U.S. 210, 29 S.Ct. 67, 58 L.Ed. 150 (1908) discussed the proceedings of the Virginia State Corporation Commission and its attempt to enforce orders fixing passenger rates. The Court noted that the corporation commission has been clothed with legislative, judicial, and executive powers.

€ 2 The Court described a judicial inquiry as one that investigates, declares, and enforces liabilities as they stand on present or past facts and under laws supposed already to exist. In contrast, legislation looks to the future and changes existing conditions by making a new rule to be applied thereafter to all or some part of those subject to its power. The Court determined that the ratemaking involved in Prentis was a legislative proceeding and reviewed the proceeding as such.

T3 The Court in Southwestern Bell Telephone Co. v. Oklahoma Corp. Com'n, 1994 OK 38, ¶ 9, 873 P.2d 1001, cert. denied, 513 U.S. 869, 115 S.Ct. 191, 130 L.Ed.2d 123 (1994) adopted the Prentis definition of legislative and judicial proceedings when we ree-ognized that due process requirements for ratemaking decisions differ significantly from due process attached to judicial proceedings. The Court noted that when the Commission sits and decides matters in its adjudicative capacity, it exercises the power of a court of record, but it determined that ratemaking is a legislative function.

1 4 We have long recognized that the Commission itself, when exercising its adjudicative authority, is the functional analogue of a court of record with dispute resolution authority conferred by Constitutional grant. In Monson v. State ex. rel. Okla. Corp. Com'n, 1983 OK 115, ¶¶ 4-5, 678 P.2d 839 we described the Corporation Commission's adjudicative powers as:

While Art. 7 § 1, Ok. Const., creates courts and invests them with judicial power, the Corporation Commission stands established and governed by the provisions of Art. 9 §§ 15-84, Ok. Const. Within the limits of authority conferred on it by constitutional provisions as well as by statutory enactments, the Commission may exercise legislative, judicial and executive power. There can be absolutely no doubt of the Commission's legitimate claim to possession - of - adjudicative - authority. When in individual proceedings it sits to hear and decide the issues before it, it acts, pursuant to Art. 9 § 19, Okl. Const., in the exercise of 'powers and authority of a court of record'. The role so constitutionally assigned to the Commission is entirely consistent both with Art. 4 § 1, OK. Const., that provides for the separation of powers, as well as with Art. 7 § 1, OK. Const., that vests judicial power in certain constitutionally-created or statutorily-established courts and tribunals.
In some of our past decisions we did refer to the Commission's adjudicative power as 'quasi-judicial'. We did this in order to distinguish it from pure judicial adjudication. The legal foundation for the Commission's dispute-settling function is different in character from that of other administrative agencies. The latter bodies derive their adjudicative authority not from a direct constitutional grant but rather from statutory delegation. The Commission's dispute-settling power clearly stands reposed in it by virtue of a direct constitutional mandate. Our fundamental law explicitly charges that body with the responsibility of a 'court of record'. In short, the Constitution's command is that, when acting in an adjudicative capacity, the Commission is to be treated as the functional analogue of a court of record. [citations omitted.]

4 5 The question becomes whether the reclassification sought here falls within the gamut of legislative ratemaking or requires a decision more akin to a judicial inquiry-one that investigates, declares, and enforces liabilities as they stand on present or past facts and under laws supposed already to exist. Rate regulation is prospective and future rates are set on the basis of forecasting of income, expenses, and profits; the focus of ratemaking is on whether the proposed rates are just and reasonable.

T6 This application is a request for reclassification of an Intrastate Retail Telecommunications Service as Basket 4 Services pursuant to Oklahoma Administrative Code 165:55-5-66(4) and 165:55-5-10.1. Under these provisions of the code, a regulated telecommunications service can be reclassified as competitive which will allow pricing flexibility without having to seek the Commission's approval.

(I 7 While the net effect of the re-classification may result in changes to the rates the company charges, the re-classification is not "ratemaking." A proceeding which merely involves rates or affects rates is not automatically "akin to legislation." For instance, in Barker v. Bond, 1941 OK 85, ¶ 0, 188 Okla. 559, 111 P.2d 507, the Court determined that, when in the course of a proceeding an adjustment of rates were impounded and refunded to patrons, the impounding and disbursing of the funds were judicial in nature. Similarly, in St. Louis & S.F. Railroad Co. v. State of Oklahoma, 1925 OK 541, ¶ 0, 116 Okla. 95, 244 P. 440, the Court noted that when a claim for a refund of an illegal transportation charge is based on an application of a wrong rate, the determination of whether a different rate from that charge is a legal rate is judicial not legislative.

T8 What is relevant is the nature of what is being decided. Here, the re-classification does not seek to establish new rules, develop new rate structures or change the rates allowed under Basket 4. What it does seek is a determination based on the presented facts as to whether the telecommunications company has met the qualifications under the existing rules to transfer services to a Basket 4. In other words, has the company met the competitive requirements to be classified as competitive and therefore eligible for treatment under an existing, alternative rate structure?

T 9 The factors include, but are not limited to: 1) the number and size of alternative providers of comparable services; 2) the extent to which comparable services are available from alternative provides in the market; 3) the ability of alternative providers to make functionally equivalent services readily available at competitive rates, terms and conditions; 4) public interest considerations; and 5) other indicators of market power with respect to a service, which may include market share, growth in market share and whether the alternative providers of comparable services are affiliated with the telecommunications service provider. The application of the facts to the five factors for the purpose of determining the existence of effective competition does not resemble rate-making. Consequently, it is "more akin to adjudication rather than legislation."

CONCLUSION

10 The majority refuses to view the proceeding as judicial rather than legislative. However, the Commission proceeded in an adjudicative capacity when it provided the explanation for waiving the five-year rule because "judicial economy would be best served." When addressing the issue of the Commission's refusal to dismiss the application as premature, the majority approves the Commission's waiver of its rules under the guise that "the preservation of judicial resources constitutes good cause to waive the rule" and that strict adherence to the rule would be a "waste of judicial resources." Interestingly, the majority will not label the proceedings as judicial, but clings to the fact that the Commission acted in a judicial capacity to resolve the remainder of the issues.

T 11 As an adjudication which is judicial in character this proceeding is subject to the due process requirements of a judicial proceeding. When the Commission sits and decides matters in its adjudicative capacity, it exercises the power of a court of record pursuant to the Okla. Const. Art. 9, § 19 and the Commission should be treated as the "functional analogue of a court of record." The majority opinion recognizes that some due process protections associated with a judicial proceeding such as notice and an opportunity to be heard, the right to present witnesses, and the right to cross examine were afforded the parties. Nevertheless, the majority stops short of a full review of due process and whether any irregularities may have resulted in its deprivation. I would not do so.

Under the Oklahoma Plan, each of SBC's intrastate retail services was assigned to group of services called a "basket." Each basket specifies a different degree of regulation based on the level of competition faced by the services in that basket. The Oklahoma Plan is designed to encourage competition in the telecommunications industry and contemplates a phased decrease in the Commission's regulatory oversight of SBC as competition increases.

The court acknowledged that the competitive injury complained of might never materialize because of intervening decisions of other actors, but said that absolute certainty of injury was not necessary. "It suffices," the court said, "for [petitioners] to show that the [Order] has 'the clear and immediate potential ... to hurt them competitively,'" and further that "this court 'has not required litigants to wait until increased competition actually occurs.'"

      . While we agree with the dissenter that the mere fact rates are involved in a proceeding does not automatically make that proceeding legislative, we firmly reject the notion (which is at least implied in the dissenting statement) that a proceeding which does not set rates must automatically be excluded from the legislative rubric. The crux of this proceeding, ie. what is being decided, is closely enough aligned with the setting of rates to support the Commission's characterization of this proceeding as legislative. The cases cited by the dissent do not contradict this conclusion. Both involve the statutory investiture of the Commission with judicial power to determine the amount of refund due and to identify the proper recipients in all disputes in which a claim is made that a public service corporation has charged an amount in excess of the lawful rate for a service. See the provisions of 17 0.S. §§ 121-122. Not only are those cases governed by a statute declaring the Commission's power to be judicial, but neither of the disputes involved in those cases is related to rates or rate making in a remotely similar fashion to that present in this proceeding.

The phrase "the Five Year Period" refers to a preceding provision and means five years after the date the ILEC opis to be regulated under the Oklahoma Plan. SBC argued before the Commission that this rule only bars a decision to reclassify services prior to the expiration of the five-year waiting period, but permits the earlier filing of an application. The Commission interpreted the rule to bar the filing of an application within five years. SBC did not seek review of that ruling.

      . In its explanation for waiving the five-year rule, the Commission refers to "judicial" economy and, in this opinion, we too use the adjective "judicial" as a generic term to describe the resources that would be wasted by holding multiple proceedings. While the term "judicial" commonly refers to the judiciary, it should go without saying that we are not using the adjective here to refer to a particular branch of the government. | In this context, it simply refers to the waste of governmental resources the Commission sought to avoid by granting the waiver. No one should misconstrue the use of this adjective as contradicting our holding that this proceeding is legislative in nature.

      . SBC tells us in its appellate brief that its services were placed into Basket 1 (non-competitive services), Basket 2 (access services), and Basket 3 (emerging competitive and optional services).
     
      
      . SBC's counsel pointed out during a hearing in this cause that there have been at least two other instances of services being moved to Basket 4 and that in neither of those cases were rates reviewed to determine whether they met the LRIC price floor. Neither the Commissioners nor any party voiced any disagreement that two such proceedings had been conducted. In its brief on appeal, SBC identified three reclassification proceedings where LRIC was not raised as an issue: Order No. 48913 issued in Cause No. PUD 200300708; Order No. 458168 issued in Cause No. PUD 200100277; and Order No. 458168 issue in Cause No. PUD 200100277.

The effective date shall be no earlier than the date the revised tariff pages are delivered."
     
      
      . The Commission found that granting SBC the relief requested does not constitute a "deregulation" of SBC. The Commission wrote:
      "'Under OAC 165:55-5-66(4), SBC Oklahoma must continue to file tariffs for these services. Furthermore, SBC Oklahoma's services must be priced above LRIC. Although SBC Oklahoma would not be required to provide LRIC studies before making a change in its tariffs, it would remain subject to the Commission's ability to enforce compliance with its rules."

      . The Order states:
      ''The prices of some services-particularly basic residential access line service-were established by the Commission a number of years ago and were found to be just and reasonable at that time. The Commission finds that it would not be in the public interest to require that those prices be automatically increased in order for the services to be reclassified to Basket 4. The Commission finds that any service reclassified in this proceeding may be placed in Basket 4 with a pricing floor of LRIC or current tariffed price, whichever is lower."
     
      
      . Although there was no evidence presented establishing either the LRIC or the current price of any of SBC's services, none of the parties disputes that the existing tariff prices are lower than LRIC. Cox stated in one of its appellate briefs that the residential services under consideration "are undoubtedly priced below LRIC."

      . Oklahoma Administrative Code 165:55-5-66 involves Pricing and it provides in pertinent part:
      The prices for services provided by an ILEC once the ILEC has implemented the Oklahoma Plan shall be determined according to the level of competition for each service. At the time of election into the Plan, services will be priced according to the current existing tariff prices as approved by the Corporation Commission....
      (4) Basket 4-Competitive Services.
      (A) Services which are competitive, pursuant to OAC 165:55-5-10.1, and for which functionally equivalent and substitute services are available will be placed in Basket 4.
      (B) The price floor for all services in this Basket will be the greater of the LRIC of the service under consideration or a price which is arrived at by applying imputation where appropriate.
      (C) Price revisions to the tariffs for services in Basket 4 shall become effective on the date specified on the revised tariff sheets after the provider has delivered 3 copies of the revised tariff sheets to the Director of the Public Utility Division. The effective date shall be no earlier than the date the revised tariff pages are delivered.
      The Oklahoma Administrative Code 165:55-5-10.1 provides:
      (a) A - telecommunications service provider may file an application to have the Commission determine that a regulated telecommu-pications service, other than local directory assistance or operator services is subject to effective competition and is therefore competitive for the applicant and/or the applicant class.
      (b) In determining whether a service is competitive, factors the Commission will consider include, but are not limited to:
      (1) The number and size of alternative providers of comparable services;
      (2) The extent to which comparable services are available from alternative providers in the relevant market;
      (3) The ability of alternative providers to make functionally equivalent or substitute services readily available at competitive rates and terms and conditions;
      (4) Public interest considerations; and,
      (5) Other indicators of market power with respect to a service, which may include market share, growth in market share and whether the alternative provider(s) of comparable services are affiliated with the telecommunications service provider.
      (c) In considering these and other factors, the Commission is not required to give equal weight to each factor in subsection (b) of this Section, but has discretion to give more weight to a particular factor or factors, based on the evidence.
      (d) As part of its order determining a service to be competitive, the Commission may require the passage of a transitional period, not to exceed two (2) years. During such transitional period, proposed tariff changes of all providers shall be deemed lawful and effective thirty (30) days after filing, unless the Commission suspends the proposed tariff change before the end of the 30-day period. If suspended, the provisions of OAC 165:55-5-13 shall apply.
      (e) Following any transitional period ordered by the Commission pursuant to subsection (d) the rates charged by a TSP for a service determined to be competitive shall become effective on the date specified on the revised tariff sheets, after the provider has delivered three
      (3) copies of the revised tariff sheets to the Director of the Public Utility Division. The effective date shall be no earlier than the date the revised tariff pages are delivered to the Director of the Public Utility Division.
      (f) Following any transitional period, ordered by the Commission pursuant to subsection (d), the terms and conditions under which competitive services are offered shall be submitted to the Director of the Public Utility Division and made available for public inspection. Changes in terms and conditions, and any combination of price and non-price components, shall be submitted at least thirty (30) days prior to when such changes shall be implemented by the provider.
      (g) Notwithstanding the provisions of this Section, the Commission may, at any time, revoke the competitive designation of a service, after notice and hearing, if the Commission determines that the service is no longer a competitive service. If the competitive designation of a service is revoked by the Commission, changes in the rates of the service or services affected shall be regulated pursuant to the provisions of OAC 165:55-5-10.
      (h) Any revised tariff for a service which has been determined to be competitive by the Commission, pursuant to this Section, shall identify the cause and order number making such designation of competitiveness.
