    IN THE COURT OF APPEALS OF THE STATE OF KANSAS
    DARIC SMITH, on behalf of himself, and all others similarly situated,
    Appellants/Cross-appellees,
    v.
    PHILIP MORRIS COMPANIES, INC.; PHILIP MORRIS INCORPORATED; PHILIP MORRIS
    INTERNATIONAL INC.; R.J. REYNOLDS TOBACCO COMPANY; BRITISH AMERICAN
    TOBACCO CO. LTD.; BROWN & WILLIAMSON TOBACCO CORP.; LORILLARD TOBACCO

    Appellees/Cross-appellants.
    SYLLABUS BY THE COURT
    1.
    Federal antitrust law is intended to supplement the remedies available under
    Kansas law, not to replace Kansas antitrust provisions. But Kansas courts do not ignore
    the multitude of cases interpreting and applying federal antitrust law. On the contrary,
    federal precedents interpreting, construing, and applying federal antitrust law can be
    persuasive authority; but this is so only as long as they do not conflict with clearly
    dissimilar provisions in the Kansas Restraint of Trade Act, K.S.A. 50-101 et seq.
    2.
    Under Kansas law, a petition is not intended to govern the entire course of the
    case. Under Kansas' liberal notice-pleading rules, the only information a plaintiff is
    required to include in a petition is: "(1) [a] short and plain statement of the claim
    showing that the pleader is entitled to relief; and (2) a demand for judgment for the relief
    to which the pleader deems such pleader's self entitled." K.S.A. 60-208. A plaintiff is
    under no obligation to categorize causes of action or cite statutory authority or common-
    law bases for the suit. Moreover, the substance of a petition prevails over its form, at least
    in the context of reviewing a dismissal of a petition for failure to state a claim under
    1
    K.S.A. 60-212(b)(6). Nevertheless, how a plaintiff deliberately states a claim and
    organizes a petition is somewhat instructive as to what claim or claims are raised in the
    lawsuit.
    3.
    How claims in a class action lawsuit are defined at the class certification stage is
    critical to satisfying due process requirements. Thus, while principles of notice pleading
    control at the outset of a case, a plaintiff must more closely define the claim or claims
    when seeking class certification. Such definiteness serves to properly define the class, to
    determine whether the filing plaintiff is a proper class representative, to define the
    question on which class certification is sought, and to adequately inform potential class
    members what claim or claims are involved so they can determine whether to opt out of
    class membership as provided in K.S.A. 2000 Supp. 60-223(c)(2). Likewise, a defendant
    in a class action case is entitled to a clear statement of the claim or claims in order to be
    protected against later suits by plaintiffs who failed to opt out of the class and who later
    assert claims identified in the class certification order and notice to the prospective class
    members.
    4.
    The certification order and class notice in a class action suit serve a purpose
    similar to a pretrial order: they each more closely define the claim or claims involved
    than required at the outset of the case under our notice-pleading rules. But a plaintiff class
    is not forever bound by the claim or claims identified in the certification order. K.S.A.
    2013 Supp. 60-223(c)(1)(C) permits modification of the certification order after the class
    has been certified.
    5.
    In an oligopolistic market controlled by few sellers, conscious parallelism,
    i.e., independent conscious but parallel pricing decisions by the market
    2
    participants, does not, in and of itself, establish a conspiracy to fix prices in the
    market.
    6.
    It is settled law in Kansas that when reasonable minds can differ as to the
    conclusions drawn from the evidence, summary judgment is inappropriate. But in the
    context of an antitrust horizontal price-fixing case, reasonable minds cannot infer that
    price-fixing is afoot merely from conscious parallel pricing conduct of oligopolists.
    Something more must be shown to establish a reasonable inference that such competitors
    acted in furtherance of an illegal conspiracy.
    7.
    To survive a motion for summary judgment, a plaintiff seeking damages for
    price-fixing under the Kansas Restraint of Trade Act, K.S.A. 50-101 et seq., based
    upon evidence of parallel pricing decisions made by competitors in an oligopoly
    market, must present evidence that tends to exclude the possibility that the alleged
    conspirators acted independently; that is, the plaintiff must present evidence that
    supports the existence of a price-fixing conspiracy more strongly than it supports
    mere conscious parallel pricing. Such evidence is referred to as "plus factors."
    8.
    Any showing by a plaintiff that tends to exclude the possibility of independent
    action can qualify as a plus factor. If a benign explanation of a defendant's action is
    equally plausible or more plausible than a collusive explanation, the action cannot
    constitute a plus factor. On the other hand, evidence that a defendant's behavior would
    not be reasonable or explicable (i.e., not in its legitimate economic self-interest) if it were
    not conspiring to fix prices can constitute a plus factor.
    3
    9.
    To be a viable plus factor, the evidence must make economic sense to a reasonable
    jury. Thus, the court must determine at the outset and as a matter of law the
    reasonableness of the inferences that can be drawn from the evidence.
    10.
    Under the facts presented, evidence of the oligopolistic structure of the cigarette
    market is relevant. But such evidence does not tend to exclude the possibility that the
    alleged conspirators acted independently. In and of itself, it does not suffice to defeat
    summary judgment on a claim of horizontal price-fixing among oligopolists. A plus
    factor must be something that tips the scales from otherwise legal synchronous conduct
    among competitors in an oligopoly to a price-fixing conspiracy condemned by our
    antitrust laws. Conscious parallelism, which is lawful conduct, arises in markets
    containing the very factors which define an oligopoly. Thus, these factors, which describe
    market characteristics for legal conscious parallelism, cannot tip the evidentiary scale out
    of equipoise so as to provide evidence from which a reasonable factfinder could infer
    illegal conduct.
    11.
    A jury could not reasonably infer that defendants conspired to fix prices from the
    mere fact that defendants had numerous opportunities to do so. The mere opportunity to
    fix prices without any showing that defendants actually conspired does not tend to
    exclude the possibility that they did not avail themselves of such opportunity or,
    conversely, that they actually did conspire. A price-fixing conspiracy cannot be inferred
    from such evidence.
    12.
    Under the facts presented, the use of an intermediary agency to exchange
    information on sales volumes does not constitute a plus factor which assists the factfinder
    4
    in determining whether defendants' synchronous pricing was the product of an illegal
    price-fixing conspiracy.
    13.
    Under the facts presented, and in light of the more recent history of vigorous price
    competition among defendants, evidence of antitrust violations more than 50 years ago is
    not indicative of a price-fixing agreement during the relevant time period.
    14.
    Evidence of actions contrary to a defendant's economic self-interest can serve as a
    plus factor. But courts necessarily must exercise prudence in labeling a given action as
    being contrary to the actor's economic interests, lest courts too quickly second guess
    well-intentioned business judgments of all kinds. Thus, to establish a plus factor from
    such evidence, it is not enough for a plaintiff to show that a particular action did not, in
    hindsight, ultimately work to the defendant's financial advantage. Nor is it enough to say
    something other than self-interest might have motivated the pricing decision. Rather, the
    action must tend to exclude the possibility of an independent action. Thus, if a benign
    explanation is equally or more plausible than a collusive explanation, the action cannot
    constitute a plus factor.
    15.
    Under the facts presented, plaintiffs' contention that defendants conspired to fix
    the prices of cigarettes in foreign countries, thereby diverting domestic cigarette supplies
    to foreign markets and increasing cigarette prices in the United States, does not constitute
    a plus factor to support a domestic price-fixing scheme when the market for cigarettes
    had been declining since the 1980's, resulting in a number of manufacturer-defendants
    having substantial excess production capacity with which to expand supply in order to
    meet any unsatisfied market demand. Evidence supporting such a theory does not tend to
    5
    establish defendants' domestic wholesale pricing was the product of an unlawful
    conspiracy.
    16.
    Under the facts presented, evidence that defendants conspired to suppress
    information on the health risks of cigarettes, thereby artificially maintaining the demand
    for and wholesale prices of cigarettes, does not have a tendency in reason to prove that
    defendants entered into an entirely separate conspiracy to fix the wholesale prices for
    cigarettes sold in Kansas.
    17.
    Appellate courts review a district court's denial of a motion to file an amended
    petition for any abuse of judicial discretion. Valid reasons for denying a motion to file an
    amended petition include (1) undue delay, (2) bad faith or dilatory motive on the part of
    the movant, (3) repeated failure to cure deficiencies by amendments previously allowed,
    (4) undue prejudice to the opposing party by virtue of allowance of the amendment, and
    (5) futility of amendment.
    18.
    Appellate courts review a district court's denial of a motion for default
    judgment for any abuse of judicial discretion. Default judgments are not favored in
    the law. Under the facts presented, the district court did not abuse its discretion in
    refusing to grant a default judgment to a class claiming damages of $7.58 billion.

    Before MCANANY, P.J., ARNOLD-BURGER and POWELL, JJ.
    MCANANY, J.: In February 2000, Daric Smith, seeking to represent a class of
    Kansas retail purchasers of cigarettes (Plaintiffs), commenced this action against several
    tobacco companies (Defendants) in the Seward County District Court, alleging they
    conspired to fix the wholesale price of cigarettes in violation of the Kansas Restraint of
    Trade Act (KRTA), K.S.A. 50-101 et seq. Defendants are: Altria Group, Inc., formerly
    Philip Morris Companies, Inc. (Altria); Philip Morris USA, Inc., a subsidiary of Altria
    (PM-USA); Philip Morris International, Inc., a subsidiary of Altria until 2008 (PMI); R.J.
    7
    Reynolds Tobacco Company (RJR); Lorillard Tobacco Company (Lorillard); Brown &
    Williamson Tobacco Corporation (B&W); Liggett Group, Inc. (Liggett); and British
    American Tobacco (Investments) Ltd. (BATCo).
    The district court certified the class with Smith as its representative. After 12 years
    of litigation and extensive discovery, the district court entered summary judgment for
    Defendants. The court found Plaintiffs failed to come forward with direct evidence or
    sufficient circumstantial evidence from which a jury could draw a reasonable inference of
    collusive behavior in fixing the wholesale price of cigarettes in Kansas. Moreover, the
    court found Plaintiffs' theory economically untenable. Plaintiffs appeal.
    Upon de novo review, and based upon the claims and the facts established during
    discovery in this case, we conclude the district court did not err in entering summary
    judgment in favor of Defendants. As we shall see in our discussion of the court's decision
    in United States v. Philip Morris USA, Inc., 
    449 F. Supp. 2d 1
    , 28 (D.D.C. 2006), aff'd in
    part and vacated in part by 
    566 F.3d 1095
     (D.C. Cir. 2009), cert. denied 
    130 S. Ct. 3502
    ,
    reh. denied 
    131 S. Ct. 57
     (2010), which we refer to in this opinion as the RICO case, the
    tobacco industry has many things to answer for to the consumers of its products. But
    based upon the facts before us, a conspiracy among these Defendants to fix the wholesale
    prices of cigarettes in Kansas in violation of the KRTA is not one of them.
    Introduction
    The tobacco industry is a classic example of an oligopoly, with a small number of
    companies controlling the majority of the market. Defendants PM-USA, RJR, B&W,
    Lorillard, and Liggett (Manufacturing Defendants) collectively manufactured more than
    97% of the cigarettes sold in the United States during the relevant time period. The
    Manufacturing Defendants sell to wholesalers at list prices, which are published to
    wholesalers on a regular basis. The wholesalers independently set their own prices to
    8
    retailers, and the retailers then set their own prices for consumers. But the ultimate price
    to the consumer is affected by a wide variety of discounts, promotions, and rebates to
    wholesalers provided by Manufacturing Defendants. See Brooke Group Ltd. v. Brown &
    Williamson Tobacco Corp., 
    509 U.S. 209
    , 239, 
    113 S. Ct. 2578
    , 
    125 L. Ed. 2d 168
    (1993); RICO case, 
    449 F. Supp. 2d at 948
    .
    Plaintiffs contend, at a minimum, that Defendants, pursuant to a conspiracy to fix
    the wholesale prices of cigarettes in the United States, engaged in lock-step price
    increases beginning on November 1, 1993, following a 7-month period of vigorous price
    competition. Before we further explore the breadth of Plaintiffs' conspiracy claim or
    claims, which is a key source of contention on appeal, we briefly consider the
    circumstances of the cigarette market leading up to that point.
    By 1980, the demand for cigarettes in the United States was in decline, resulting in
    substantial excess capacity among the various manufacturers. Liggett, whose market
    share declined over the years from over 20% to barely 2%, responded by introducing in
    1980 generic cigarettes at a list price of about 30% less than the regular brands. As the
    sale of Liggett's generics increased, RJR responded in 1983 with its own generic brand,
    and B&W followed suit in the spring of 1984. Throughout the 1980's and early 1990's,
    the discount segment of the cigarette market grew dramatically, taking market share away
    from premium brands, such as PM-USA's flagship brand Marlboro. By 1993, discount
    cigarettes accounted for 38.9% of industry shipments.
    The growing discount segment had a particularly negative effect on PM-USA,
    with Marlboro losing market share at an accelerated rate for the first time in decades. For
    Marlboro to remain competitive, PM-USA concluded it needed to narrow the gap
    between the price of Marlboro and the lowest priced discount brands.
    9
    Thus, on April 2, 1993, a day which came to be known as "Marlboro Friday," PM-
    USA announced a nationwide Marlboro retail promotion that reduced retail prices by an
    average of 40 cents per pack, or approximately 20%. Four months later, PM-USA
    followed this retail promotion with national wholesale list price reductions on all of its
    premium and discount brands.
    These moves successfully reduced the price gap between Marlboro and the
    discount brands, resulting in Marlboro regaining its market share. The other
    Manufacturing Defendants followed PM-USA's price moves. Plaintiffs contend these
    price moves were the result of an illegal combination or conspiracy to fix prices. On the
    other hand, Defendants contend they made these pricing moves independent of one
    another. As support, they point to uncontroverted evidence that they argue is inconsistent
    with the notion of these pricing moves being the product of an agreement among
    competing suppliers.
    The scope of Plaintiffs' claim or claims against Defendants became a key source of
    contention in the district court and remains so in this appeal. The case is now before us
    because the district court found Plaintiffs stated only a claim for a wholesale price-fixing
    conspiracy and granted Defendants summary judgment on that claim.
    Plaintiffs' contentions on appeal center on two points. First, they insist the district
    court too narrowly interpreted the scope of their restraint-of-trade claim. Second, they
    contend that even if we find otherwise, summary judgment on a wholesale price-fixing
    claim is improper under Kansas law.
    Standard of review
    In our de novo review of Defendants' motions for summary judgment, we apply
    the same summary judgment standards as those applied by the district court. Those
    10
    standards dictate that summary judgment is appropriate only when the pleadings,
    depositions, answers to interrogatories, and admissions on file, together with the
    affidavits, show that there is no genuine issue as to any material fact and that the moving
    party is entitled to judgment as a matter of law. We resolve all facts and inferences that
    may reasonably be drawn from the evidence in favor of Plaintiffs, the party against
    whom the summary judgment was sought. We must deny Defendants' summary judgment
    motions if reasonable minds could differ as to the conclusions drawn from the evidence.

    294 Kan. 318
    , 330, 
    277 P.3d 1062
    (2012) (O'Brien I).
    SCOPE OF PLAINTIFFS' CLAIM
    Defendants tell us this is one of many antitrust cases filed across the country
    involving the same claim against some of them for conspiring to fix the wholesale prices
    of cigarettes following Marlboro Friday. All of those other cases have now been either
    voluntarily dismissed or ended in summary judgment for the tobacco companies. See,
    e.g., Holiday Wholesale Grocery v. Philip Morris Inc., 
    231 F. Supp. 2d 1253
    , 1329 (N.D.
    Ga. 2002), aff'd sub nom. Williamson Oil Co., Inc. v. Philip Morris USA, 
    346 F.3d 1287
    (11th Cir. 2003) (granting summary judgment against class of cigarette wholesalers in
    multidistrict litigation [MDL] on wholesale price-fixing claim brought against PM-USA,
    RJR, B&W, and Lorillard under federal antitrust law); Romero v. Philip Morris Inc., 
    148 N.M. 713
    , 729-32, 
    242 P.3d 280
     (2010) (applying Williamson Oil analysis in affirming
    summary judgment for same tobacco companies involved in this case on claim of
    wholesale price-fixing conspiracy brought by class of indirect cigarette purchasers under
    New Mexico's antitrust laws); Ren v. Philip Morris Companies, Inc., No. 00-004035-CZ,
    unpublished Michigan Circuit Court opinion filed September 10, 2003 (same under
    Michigan antitrust law). Defendants insist the district court properly held the same result
    is proper in this case brought under the KRTA.
    11
    The governing substantive law
    Before we determine what claim or claims are involved in this case, a brief
    overview of the governing law is in order. First, we note that substantial changes to the
    KRTA were enacted by our legislature in response to our Supreme Court's opinion in
    O'Brien I. Those changes were effective April 18, 2013, but do not apply retroactively to
    cases, like this one, already pending at the time. See K.S.A. 2013 Supp. 50-164; Owen
    Lumber Co. v. Chartrand, 
    276 Kan. 218
    , 220-21, 
    73 P.3d 753
     (2003). Those changes
    included: (1) The repeal of the full-consideration damages provision in K.S.A. 50-115,
    which allowed a successful plaintiff to recover the full consideration paid for goods
    "controlled in price by such combination" and which are claimed by Plaintiffs in our
    present case; (2) a declaration that provisions of the KRTA shall be "construed in
    harmony" with the United States Supreme Court's interpretations of federal antitrust law;
    and (3) permitting a rule-of-reason analysis by an explicit allowance for "reasonable
    restraint[s] of trade or commerce." K.S.A. 2013 Supp. 50-163(b), (c); L. 2013, ch. 102,
    sec. 7. Our present case proceeds under the pre-April 18, 2013, version of the KRTA.
    Both the KRTA and its federal counterpart, the Sherman Act, 
    15 U.S.C. § 1
     (2012)
    et seq., contain broad language that bans a wide range of activities that restrict or restrain
    trade. Section 1 of the Sherman Act broadly declares illegal "[e]very contract,
    combination in the form of trust or otherwise, or conspiracy, in restraint of trade or
    commerce among the several States, or with foreign nations." 
    15 U.S.C. § 1
    . The cases
    are legion in which federal courts have been called upon to interpret and to apply this
    language. Federal antitrust law, however, does not control here. Rather, as our Supreme
    Court recently stressed, "federal antitrust law is intended to supplement the remedies
    available under Kansas law, not to replace Kansas antitrust provisions." O'Brien I, 294
    Kan. at 322. But we do not ignore the multitude of cases interpreting and applying the
    Sherman Act. On the contrary, federal precedents interpreting, construing, and applying
    federal antitrust law can be persuasive authority; but this is so only as long as they do not
    12
    conflict with clearly dissimilar provisions in the KRTA. See 294 Kan. at 322, 342-43. We
    will come back to these principles later.
    In their first amended petition, under which this case has been litigated since
    March 2001, Plaintiffs broadly alleged that Defendants violated "K.S.A. 50-101 through
    K.S.A. 50-117, K.S.A. 50-139 through K.S.A. 50-147, and K.S.A. 50-801." But our
    review of the vast record reveals that Plaintiffs' substantive statutory focus has
    consistently been K.S.A. 50-112, from their successful efforts resisting Defendants' early
    efforts to have this action dismissed for failure to state a claim to the more recent battles
    over the appropriateness of summary judgment. Moreover, full-consideration damages
    under K.S.A. 50-115 that Plaintiffs seek were the focus of their expert witnesses' report in
    support of class certification. Full-consideration damages are only available under K.S.A.
    50-115 for violations of K.S.A. 50-112 (and the unrelated prohibitions of K.S.A. 50-113
    involving the creation of certain trusts). See O'Brien v. Leegin Creative Leather
    Products, Inc., No. 108,988, 
    2014 WL 1362657
    , at *7-8 (Kan. App. 2014) (unpublished
    opinion) (O'Brien II). K.S.A. 50-112 is clearly where we must focus our attention.
    K.S.A. 50-112 broadly declares the following to be "against public policy,
    unlawful and void":
    "[A]ll arrangements, contracts, agreements, trusts, or combinations between persons
    made with a view or which tend to prevent full and free competition in the importation,
    transportation or sale of articles imported into this state, or in the product, manufacture or
    sale of articles of domestic growth or product of domestic raw material, . . . and all
    arrangements, contracts, agreements, trusts or combinations between persons, designed or
    which tend to advance, reduce or control the price or the cost to the producer or to the
    consumer of any such products or articles . . . or any other services . . . ."
    We can envision a wide variety of concerted activities in restraints of trade that
    might fall under the broad proscription of K.S.A. 50-112. Businesses arguably could
    13
    violate K.S.A. 50-112 by allocating customers or sales territories, agreeing not to
    compete on a particular product line, agreeing to limit production or variations in the
    quality of competing products, controlling hours of operation, or agreeing to fix prices.
    These examples do not exhaust the possibilities. But the issue here is the theory or
    theories Plaintiffs have pursued in this case.
    In response to Smith's original petition, Defendants filed various motions to
    dismiss for failure to state a claim and, in the alternative, asked the court to coordinate the
    discovery in this case with the discovery taking place in the federal MDL that ultimately
    led to the decision in Williamson Oil. In their written opposition to those motions,
    Plaintiffs consistently referred to a "fraudulent price fixing conspiracy" or "the price
    fixing agreement," to Defendants as "alleged price fixing conspirators," and to
    Defendants' various detrimental acts as "price fixing." In at least one early pleading,
    Plaintiffs even cross-referenced smoking and health conspiracies that were being raised
    elsewhere as separate from the conspiracy they were raising in this case. More
    specifically, in responding to at least one motion to dismiss filed prior to class
    certification, Plaintiff Smith rebutted certain foreign Defendants' suggestions that
    discovery on the issue of whether the court could exercise jurisdiction over them would
    be unduly burdensome by noting: "Foreign Defendants admit that their domestic
    subsidiaries have already 'posted millions of pages of its documents on the internet' in
    smoking and health actions." Plaintiffs then argued:
    "It is virtually common knowledge that the tobacco companies have been
    attempting to create shells of corporations in an effort to avoid the inevitable massive
    liability for their prior conspiracies on addictive nicotine and cigarette cancer causing
    issues which have now come home to roost in one case in Florida in which the domestic
    subsidiaries alone have been hit for $145 billion. It is no small wonder that Foreign
    Defendants are looking to protect their own assets, but much of this shell game was done
    after the conspiracy set forth herein began and much of the Foreign Defendants['] shells
    were set up from the unfair profits of the conspirators." (Emphasis added.)
    14
    During a hearing on the motions to dismiss conducted in August 2000, Plaintiffs
    distinguished their case from the federal MDL solely on the bases that the federal
    procedural rules, laws of evidence, and substantive law that governed the MDL case
    differed from Kansas law. In particular, they focused on the distinction between the class
    in the MDL (direct purchasers) versus the class they proposed (indirect purchasers). They
    never suggested during these early proceedings that they were raising a substantive claim
    other than a wholesale price-fixing conspiracy.
    In March 2001, Plaintiffs filed their first amended petition, the pleading under
    which this case has been litigated since then.
    Under Kansas law, a petition is not intended to govern the entire course of the
    case. Berry v. National Medical Services, Inc., 
    292 Kan. 917
    , 918, 
    257 P.3d 287
     (2011).
    In fact, under Kansas' liberal notice-pleading rules, the only information Plaintiffs were
    required to include in their petition was: "(1) A short and plain statement of the claim
    showing that the pleader is entitled to relief; and (2) a demand for judgment for the relief
    to which the pleader deems such pleader's self entitled." K.S.A. 60-208; see also Oller v.
    Kincheloe's, Inc., 
    235 Kan. 440
    , 446-48, 
    681 P.2d 630
     (1984) (outlining various
    principles underlying concept of notice pleading under Kansas law). Plaintiffs were under
    no obligation to categorize their causes of action or cite statutory authority or common-
    law bases for the suit. See Golden v. Den-Mat Corporation, 
    47 Kan. App. 2d 450
    , 461,
    
    276 P.3d 773
     (2012). Moreover, the substance of a petition prevails over its form, at least
    in the context of reviewing a dismissal of a petition for failure to state a claim under
    K.S.A. 60-212(b)(6). See Baska v. Scherzer, 
    283 Kan. 750
    , 755, 
    156 P.3d 617
     (2007).
    Nonetheless, how Plaintiffs deliberately organized their first amended petition is
    somewhat instructive on just what claim or claims they raised in their lawsuit. Plaintiffs'
    first amended petition is divided into 55 numbered paragraphs which fall under 9 main
    sections. Plaintiffs assigned the following headings to those sections:
    15
    I.     NATURE OF THIS ACTION
    II.    PARTIES
    III.   CO-CONSPIRATORS, AIDERS AND ABETTORS, AND JOINT
    VENTURERS
    IV.    JURISDICTIONAL ALLEGATIONS
    V.     CLASS ACTION ALLEGATIONS
    VI.    TRADE AND COMMERCE IN KANSAS
    VII.   FACTUAL BACKGROUND
    A.     General Price Fixing Information
    B.     Violation of Antitrust Laws
    C.     The Illegal Effect on Markets in Kansas
    D.     Fraudulent Concealment, Equitable Tolling, Discovery Rule,
    Continuous Tort
    VIII. INJURY TO PLAINTIFF AND PLAINTIFF'S CLASS
    IX.    PRAYER FOR RELIEF.
    In the prayer for relief and at various points throughout their petition, Plaintiffs
    consistently referred broadly to a singular "unlawful combination and conspiracy alleged
    [t]herein." The same is true of the "class allegations," particularly with regard to the
    questions of law and fact alleged to be common to the class. Plaintiffs specifically
    detailed how that "combination and conspiracy" violated the KRTA under section VII. B.
    of their first amended petition. That section opens with the allegation that "[b]eginning no
    later than November 1, 1993[,] Defendants and their co-conspirators entered into and
    engaged in a combination and conspiracy to suppress and eliminate competition by fixing
    the price of Cigarettes offered for sale to customers in this state and elsewhere."
    (Emphasis added.) Allegations under that same subheading continue:
    16
    "43. Specifically, Defendants illegally:
    "a. created or carried out restrictions in trade or commerce, by e.g. setting by
    agreement the prices which the Defendants charged for Cigarettes which,
    directly or indirectly, were sold in Kansas;
    "b. prevented competition in the manufacture or sale of Cigarettes sold, directly
    or indirectly, in Kansas by, agreeing among themselves not to compete over
    prices;
    "c. fixed the price of Cigarettes in such a way as to inflate, stabilize, control or
    establish, at least in part, the prices paid in Kansas;
    "d. entered into, executed, and carried out contracts, obligations, and agreements
    in which they: (i) bound themselves not to sell Cigarettes below a fixed
    price; (ii) agreed to keep the prices of Cigarettes at a fixed price; (iii)
    coordinated price increases; and (iv) established and settled the price of
    Cigarettes so as to directly or indirectly preclude a free and unrestricted
    competition among themselves and other co-conspirators; and
    "e. issued price announcements and price quotations in accordance with the
    above-described agreements.
    ....
    "47. [Plaintiffs] were injured in their trade or business by reason of the unlawful acts of
    Defendants as alleged herein (the wholesaler and distributors who directly purchased
    Cigarettes from the Defendants paid higher prices for Cigarettes and then passed on these
    additional costs to their customers and to the ultimate consumers). As a result, [Plaintiffs]
    were forced to pay higher prices for the Cigarettes they purchased than they would have
    had to pay if the prices charged by Defendants to their customers were the product of fair
    and open competition and not of an illegal price-fixing agreement.
    "48. During the period of the conspiracy, Defendants and other co-conspirators held
    meetings during which they agreed to and did [eliminate], suppress and limit competition
    by:
    "a. discussing the prices and volumes of Cigarettes;
    "b. agreeing to increase and maintain prices on Cigarettes; and
    "c. discussing and agreeing on methods to conceal the agreements and carrying
    out the charged conduct.
    17
    "49.      Defendants have issued price announcements in accordance with the agreements,
    and have participated in meetings and conversations to monitor and enforce adherence to
    the agreed-upon prices in the United States, including the State of Kansas." (Emphasis
    added.)
    The remaining sections of the first amended petition, likewise, focus solely on allegations
    of conspiratorial price-fixing by Defendants.
    But Plaintiffs now insist their claim has never been limited to domestic or national
    wholesale price-fixing. To the contrary, they proclaim in their appellate brief they have
    always "alleged an international non-price and price conspiracy." They describe that
    claim as a "'restraint of trade claim,'" with three distinct components:
    (1) A domestic wholesale price-fixing conspiracy like that involved in the
    federal MDL.
    (2) A "demand-shift" or "smoking and health" conspiracy based on
    allegations that Defendants kept the demand for cigarettes artificially high,
    thereby keeping the price high by, for example, concealing information,
    falsely advertising, and actively misleading the public about what they
    knew concerning the addictive nature of nicotine and the adverse effects of
    smoking on health. They alleged that "[i]f consumers had received full,
    accurate information regarding the adverse effects of cigarettes, including
    how addictive cigarettes were, they would have purchased fewer cigarettes,
    demand would have been lower, and the price lower."
    (3) A "supply-restriction" or international price-fixing conspiracy based on
    allegations that Defendants conspired to fix the price of cigarettes in foreign
    countries, thereby "'increas[ing] the incentive to export cigarettes,'" which,
    18
    in turn, reduced domestic cigarette supply, causing an increase in domestic
    cigarette prices.
    According to Plaintiffs, the smoking and health conspiracy has always been the
    "core theory" and "biggest and best part" of their case. They also insist the nonprice,
    smoking and health component of their restraint-of-trade claim is based on the same
    activities that underlie the charges brought by the United States Department of Justice
    against the same tobacco companies who are Defendants in our case for violations of the
    Racketeer Influenced and Corrupt Organizations Act (RICO), 
    18 U.S.C. §§ 1961-1968
    .
    Those RICO charges ultimately led to a 9-month bench trial in an "extraordinarily
    complex case" that resulted in an almost 1,000-page decision by the federal district court
    in United States v. Philip Morris USA, Inc., 
    449 F. Supp. 2d 1
    , 28 (D.D.C. 2006), aff'd in
    part and vacated in part by 
    566 F.3d 1095
     (D.C. Cir. 2009), cert. denied 
    130 S. Ct. 3502
    ,
    reh. denied 
    131 S. Ct. 57
     (2010) (the RICO case). In its prefatory summary to that
    opinion, the federal district court found: "In short, Defendants have marketed and sold
    their lethal product with zeal, with deception, with a single-minded focus on their
    financial success, and without regard for the human tragedy or social costs that success
    exacted." 
    449 F. Supp. 2d at 28
    . The court further held the government produced
    "overwhelming evidence to support most of [its] allegations" that, "for approximately
    fifty years," Defendants violated RICO (specifically 
    18 U.S.C. § 1962
    [c] and [d] by
    "falsely and fraudulently den[ying]: (1) that smoking causes lung cancer and emphysema
    (also known as chronic obstructive pulmonary disease ('COPD')), as well as many other
    types of cancer; (2) that environmental tobacco smoke causes lung cancer and endangers
    the respiratory and auditory systems of children; (3) that nicotine is a highly addictive
    drug which they manipulated in order to sustain addiction; (4) that they marketed and
    promoted low tar/light cigarettes as less harmful when in fact they were not; (5) that they
    intentionally marketed to young people under the age of twenty-one and denied doing so;
    and (6) that they concealed evidence, destroyed documents, and abused the attorney-
    19
    client privilege to prevent the public from knowing about the dangers of smoking and to
    protect the industry from adverse litigation results." 
    449 F. Supp. 2d at 27
    .
    In support of Plaintiffs' contention that they claim a conspiracy to maintain
    cigarette prices by hiding the deleterious effects of tobacco, Plaintiffs point to various
    allegations in their first amended petition, but they particularly rely upon Paragraph 33,
    which appears immediately between the heading "VII. FACTUAL BACKGROUND"
    and subheading "A. General Price Fixing Information." Paragraph 33 states:
    "Defendants, along with their affiliates, combined and conspired on a worldwide basis
    which adversely effected [sic] the United States, including Kansas. Defendants'
    conspiracy included price-fixing agreements as well as non-price agreements, which
    helped provide a foundation and support mechanism for the price-fixing conspiracy.
    Defendants' non-price agreements included, but were not limited to, the joint creation of
    false impressions regarding the health effects of cigarette smoking; the joint control of
    internal scientific research; the joint control of product advertising; the joint restriction
    from researching and introducing 'safer' cigarettes; the joint use of legal counsel and
    others to hide their conspiracy; and the joint coordination of marketing activities. The
    price fixing conspiracy was intended to directly enhance the profitability of the industry
    as a whole, and thereby each individual company, and even included an integrated
    enforcement mechanism so that the group could 'retaliate' against any unilateral activity
    by an individual company defendant. This broad conspiracy lasted from at least
    November 1, 1993 to the present (the 'Class Period')." (Emphasis added.)
    The primary nonprice conspiracies Plaintiffs refer to here are: (1) The claimed
    conspiracy to fix cigarette prices in foreign markets and thereby artificially affect the
    available supply of cigarettes in the domestic market, and (2) the conspiracy among
    Defendants to hide from the public the deleterious effects of smoking, thereby artificially
    affecting the demand for cigarettes. Plaintiffs describe these as "help[ing] provide a
    foundation and support mechanism for the price-fixing conspiracy." We will discuss
    these theories later in some detail.
    20
    Defendants respond that Plaintiffs are improperly trying to proceed on entirely
    different conspiracy theories than the price-fixing theory under which Plaintiffs obtained
    class certification. They urge us to instead agree with the district court's ultimate
    conclusion that Plaintiffs stated only a claim for a wholesale price-fixing conspiracy.
    The parties' opposing positions demonstrate that we cannot resolve the issue of the
    nature of Plaintiffs' claim or claims simply by referring to the first amended petition.
    Accordingly, we look further into the proceedings below to see just what claim or claims
    were involved.
    The next major step in the proceedings involved Plaintiffs' motion for class
    certification. There are four statutory threshold prerequisites to bringing a class action in
    Kansas. A class action is only proper if (1) the number of class members is so large that
    joinder of all members is impracticable; (2) the class claims present common questions of
    fact or law; (3) the named parties' claims and defenses are representative of the claims
    and defenses of the other class members; and (4) the class representatives will fairly and
    adequately protect the interests of the class as a whole. K.S.A. 2000 Supp. 60-223(a).
    These threshold elements are commonly identified in shorthand as "(1) numerosity, (2)
    commonality, (3) typicality, and (4) adequacy of representation." Dragon v. Vanguard
    Industries, Inc., 
    277 Kan. 776
    , 778, 
    89 P.3d 908
     (2004). Plaintiffs sought class
    certification under K.S.A. 2000 Supp. 60-223(b)(3). At the time, that statute required, as
    it still does today, that to certify a class, the court must find: "[Q]uestions of law or fact
    common to the members of the class predominate over any questions affecting only
    individual members, and that a class action is superior to other available methods for the
    fair and efficient adjudication of the controversy." K.S.A. 2000 Supp. 60-223(b)(3). The
    statute continued:
    "The matters pertinent to the findings include: (A) The interest of members of the class
    in prosecuting or defending separate actions; (B) the extent and nature of any litigation
    21
    concerning the controversy already begun by or against members of the class; (C) the
    appropriate place for maintaining, and the procedural measures which may be needed in
    conducting, a class action." K.S.A. 2000 Supp. 60-223(b)(3).
    Notably, in insisting this case satisfied the statutory threshold prerequisites for a
    class action, Plaintiffs never disputed that they were raising the same wholesale price-
    fixing claim raised in the federal MDL. In their motion for class certification, Plaintiffs
    even referred to the then-pending MDL as "the parallel federal direct purchaser action."
    They distinguished their case primarily on the bases that they were a class of indirect
    purchasers and that certain applicable substantive law and procedural rules varied.
    We need only look to the introduction to the motion for class certification filed in
    February 2001 to demonstrate the point. That introduction states:
    "Plaintiff moves this Court to certify a class consisting of persons who were
    indirect purchasers of cigarettes in Kansas and victims of a conspiracy to fix prices and
    allocate markets for the sale of cigarettes. For almost a decade, the world's largest
    cigarette manufacturers met in secret to agree upon the method to artificially raise the
    prices of cigarettes sold in the United States and Kansas. These price increases were
    passed on through the distribution chain such that prices to Kansas consumers were
    artificially increased for an extended period of time.
    "There is currently a consolidated federal direct purchaser class action pending in
    the Northern District of Georgia [the federal MDL] which involves the same Defendants
    (except Liggett Group, Inc. and Brooke Group Ltd.) and alleges the same basic
    conspiracy as alleged in this matter. In the federal action, the Defendants have
    recognized the amenability of the cigarette industry to class treatment and have already
    stipulated to a class action for a four year class period. . . . The federal court certified the
    class on January 23, 2001." (Emphasis added.)
    Reading further into the motion only confirms the point. Following this
    introductory paragraph, Plaintiffs set forth allegations almost identical to those found in
    22
    the "factual background" section of their first amended petition. They included the same
    language found in Paragraph 33 of their petition as quoted above in the motion, which
    they characterized as "factual information" that "supports Plaintiff's allegations of
    Defendants' antitrust violations," not as separate conspiracy claims common to the
    proposed class. From there, Plaintiffs emphasized that they raise a "single" horizontal
    price-fixing conspiracy in arguing that the requirements for certifying a class in K.S.A.
    2000 Supp. 60-223(a) and K.S.A. 2000 Supp. 60-223(b)(3) were satisfied. Plaintiffs did
    not take a contrary position during any of the ensuing hearings on various aspects of class
    certification. Moreover, the report of Plaintiffs' expert witness at the class certification
    stage focused almost exclusively on the three available theories or methods that may be
    available for calculating the class' damages "due to an unlawful conspiracy to fix the
    wholesale price of cigarettes from November 1, 1993 to the present."
    Defendants' joint response in opposition to the motion for class certification
    identified Plaintiffs' claim as involving only wholesale price-fixing as well. Defendants'
    focus was upon a lack of a common class-wide method for proving impact and damages
    for each member of the putative class of indirect purchasers. Plaintiffs' reply did not
    suggest in any way that they had raised any broader claim.
    The district court ultimately found the proposed class suitable for certification and
    granted Plaintiffs' motion. In making its findings concerning the statutory threshold
    prerequisites for a class action, the court identified wholesale price-fixing as the class'
    claim in its certification order. In particular, the court noted: "There is but a single
    conspiracy claimed by the Plaintiffs in this case and if it is proven, it affects all of the
    proposed class members equally." The certification order defines the class as: "'All
    natural persons who indirectly purchased cigarettes in the State of Kansas for
    consumption and not for resale from any of the Defendants, or any parent, subsidiary or
    affiliate thereof or their co-conspirators at any time from November 1, 1993 to the
    present.'"
    23
    During proceedings to determine the form of notice to be provided to prospective
    class members, Plaintiffs persisted in their position that they stated only a claim for a
    nationwide wholesale price-fixing conspiracy. In fact, in the class notice proposed by
    Plaintiffs, they described the background of their case as follows:
    "The Plaintiff Class, which is a Kansas Class of consumers of cigarettes, allege
    that since November 1, 1993, [Defendants] have unlawfully agreed to fix the wholesale
    price of cigarettes and that, as a result, [indirect] buyers of cigarettes in Kansas have paid
    higher prices than they otherwise would have paid. The Defendants deny liability and
    have denied these claims and charges." (Emphasis added.)
    The notice ultimately approved by the district court and served on potential class
    members tracks this language.
    How claims are defined at the class certification stage is critical to satisfy due
    process requirements. See Mullane v. Central Hanover Tr. Co., 
    339 U.S. 306
    , 314-15, 
    70 S. Ct. 652
    , 
    94 L. Ed. 865
     (1950) (generally observing that notice and opportunity to be
    heard are fundamental requisites of the constitutional guarantee of procedural due process
    in context of discussing propriety of class action notice by publication). As explained in
    Mullane, 
    339 U.S. at 313
    , "[m]any controversies have raged about the cryptic and
    abstract words of the Due Process Clause but there can be no doubt that at a minimum
    they require that deprivation of life, liberty or property by adjudication be preceded by
    notice and opportunity for hearing appropriate to the nature of the case." See DeJulius v.
    New England Health Care Emp. Pension, 
    429 F.3d 935
    , 943-44 (10th Cir. 2005) (citing
    Fifth Amendment to the United States Constitution; Eisen v. Carlisle & Jacquelin, 
    417 U.S. 156
    , 173, 
    94 S. Ct. 2140
    , 
    40 L. Ed. 2d 732
     [1974]; and Mullane, 
    339 U.S. at 313
    , in
    pointing out that "[i]n addition to the requirements of Rule 23, the constitution's Due
    Process Clause also guarantees unnamed class members the right to notice of certification
    or settlement").
    24
    Our own Supreme Court has explained in discussing due process principles
    underlying the requirements of class notice:
    "The class action is premised on the theory that members of the class who are not
    before the court can justly be bound because the self-interest of their representative
    coincides with the interest of the members of the class and will assure adequate litigation
    of the common issues. Where the interests of absent class members have not been
    adequately represented, binding them by the class judgment would seem to offend the
    requirements of due process. (Hansberry v. Lee, [
    311 U.S. 32
    , 
    61 S. Ct. 115
    , 
    85 L. Ed. 22
    (1940)].) Notice to absent members of the class in this regard is particularly important,
    for it is the greatest single safeguard against inadequate representation. (Mullane, [339
    U.S.] at 314.)" Shutts, Executor v. Phillips Petroleum Co., 
    222 Kan. 527
    , 556, 
    567 P.2d 1292
     (1977).
    Accord Amchem Products, Inc. v. Windsor, 
    521 U.S. 591
    , 621, 
    117 S. Ct. 2231
    , 
    138 L. Ed. 2d 689
     (1997) (noting counterparts to K.S.A. 2000 Supp. 60-223[a] and [b] found in
    Rule 23 of Federal Rules of Civil Procedure [FRCP], "focus court attention on whether a
    proposed class has sufficient unity so that absent members can fairly be bound by
    decisions of class representatives"). Our Supreme Court has further commented on this
    subject:
    "'Class actions are designed to provide an "economical means for disposing of
    similar lawsuits" while simultaneously "protecting defendants from inconsistent
    obligations and the due process rights of absentee class members." [Citations omitted.]
    The underlying question in any class action certification is whether the class action
    device provides the most effecting and just method to resolve the controversy at hand.'
    [Citation omitted.]" (Emphasis added.) Critchfield Physical Therapy v. The Taranto
    Group, Inc., 
    293 Kan. 285
    , 303-04, 
    263 P.3d 767
     (2011).
    See 3 Rubenstein, Newberg on Class Actions § 7:26 (5th ed. 2013) (discussing due
    process principles underlying requirement in FRCP 23(c)(1)(B) that "'[a]n order that
    25
    certifies a class action must define the class and the class claims, issues, or defenses,'"
    which language mirrors statutory language currently found in K.S.A. 2013 Supp. 60-
    223[c] but was not part of K.S.A. 2000 Supp. 60-223 when the court issued the
    certification order in this case).
    Thus, we conclude that while principles of notice pleading control at the outset of
    a case, a plaintiff must necessarily more closely define the claim or claims when seeking
    class certification. Such definiteness serves to properly define the class, to determine
    whether the filing plaintiff is a proper class representative, to define the question on
    which class certification is sought, and to adequately inform potential class members of
    what claim or claims are involved so they can determine whether to opt out of class
    membership as provided under K.S.A. 2000 Supp. 60-223(c)(2).
    Our courts have not yet considered at length the need to define the claim or claims
    at the class certification stage, but the federal courts have. For example, the United States
    Supreme Court has explained:
    "As we noted in Coopers & Lybrand v. Livesay, 
    437 U.S. 463
    , [469, 
    98 S. Ct. 2454
    , 
    57 L. Ed. 2d 351
     (1978)], 'the class determination generally involves considerations that are
    "enmeshed in the factual and legal issues comprising the plaintiff's cause of action."'
    [Citations omitted.] Sometimes the issues are plain enough from the pleadings to
    determine whether the interests of the absent parties are fairly encompassed within the
    named plaintiff's claim, and sometimes it may be necessary for the court to probe behind
    the pleadings before coming to rest on the certification question." General Telephone Co.
    of Southwest v. Falcon, 
    457 U.S. 147
    , 160, 
    102 S. Ct. 2364
    , 
    72 L. Ed. 2d 740
     (1982).
    The Third Circuit Court of Appeals also considered the necessity of defining the claim or
    claims at the class certification stage in Wachtel v. Guardian Life Ins. Co., 
    453 F.3d 179
    ,
    184 (3d Cir. 2006). That court ultimately held:
    26
    "[T]he proper substantive inquiry for an appellate tribunal reviewing a certification order
    for Rule 23(c)(1)(B) compliance is whether the precise parameters defining the class and
    a complete list of the claims, issues, or defenses to be treated on a class basis are readily
    discernible from the text either of the certification order itself or of an incorporated
    memorandum opinion." 
    453 F.3d at 185
    .
    In arriving at this holding, the Third Circuit explained several policy reasons underlying
    the need for a clear definition of the class' claim or claims at the certification stage. We
    find the following discussion by the Third Circuit particularly pertinent here:
    "We acknowledge that class actions often present extraordinarily complex factual
    and legal scenarios, such that a complete list of the claims, issues, or defenses appropriate
    for class treatment may be difficult to discern or articulate at the time of certification. In
    addition, the 2003 amendments to the Rule eliminated so-called 'conditional'
    certifications—formerly available under Rule 23(c)(1)(C)—such that a trial court may
    not certify only a limited list of class claims or issues while explicitly delaying decision
    on other claims. The potential difficulty posed by the requirements of Rule 23(c)(1)(B),
    however, is tacitly acknowledged and directly mitigated by amended Rule 23(c)(1)(C),
    which allows that a certification order may be 'altered or amended' at any time 'before
    final judgment.' Furthermore, to the extent that circumstances genuinely warrant some
    evolution in the matters to be treated on a class basis in a given action, the full and clear
    articulation of those claims, issues, or defenses intended to be treated on a class basis at
    the time of the original certification order will provide a defined status quo that likely
    will serve to streamline any later process of adjustment." 
    453 F.3d at
    186-87 n.8.
    Granted, when the class was certified in this case approximately 13 years ago,
    K.S.A. 2000 Supp. 60-223 did not explicitly include the requirement to define the claim
    or claims involved. Moreover, the class was certified before much of the discovery was
    conducted, and there has not yet been a pretrial conference in this case. Nonetheless, we
    conclude that the certification order and class notice serve a purpose similar to a pretrial
    order: they each necessarily more closely define the claim or claims involved than
    required early in the case under our notice-pleading rules.
    27
    This is not to say that a plaintiff class is forever bound by the claim or claims
    identified in the certification order. On the contrary, there are statutory provisions
    allowing for modification of the certification order after the class has been certified. See
    K.S.A. 2013 Supp. 60-223(c)(1)(C) ("An order that grants or denies class certification
    may be altered or amended before final judgment."); accord General Telephone, 
    457 U.S. at 160
     (noting that under Rule 23 of FRCP, "[e]ven after a certification order is entered,
    the judge remains free to modify it in the light of subsequent developments in the
    litigation. . . . This flexibility enhances the usefulness of the class-action device; actual,
    not presumed, conformance with Rule 23[a] remains, however, indispensable.").
    To the extent that such a modification materially alters the nature of the claim or
    relief sought, it seems to us that the same due process principles discussed above dictate
    that an amended notice would need to be provided to class members. Here, Plaintiffs did
    not move to file a second amended petition until after the court's determination in July
    2011 that they had alleged only a singular claim of price-fixing that was unrelated to the
    smoking and health conspiracies litigated in the RICO case. Even then, they explicitly did
    so only to "clarify" that they had always raised a broader "restraint of trade" claim with
    both price and nonprice components. Plaintiffs never sought to modify the class
    certification order or to serve an additional class notice when discovery was complete,
    when Defendants moved for summary judgment, or even when the district court ruled
    that Plaintiffs' claim was limited to a wholesale price-fixing conspiracy.
    Applying these due process principles to the facts of this case, we find the
    wholesale price-fixing claim on which the class was certified and notice was provided to
    be significantly distinct from the nonprice component or smoking and health component
    that Plaintiffs contend was part of their case from the beginning. A class member
    deciding not to opt out of a price-fixing class would have no reason to believe that he or
    she would also be barred from bringing a future action for an antitrust conspiracy not
    involving direct price-fixing, such as rigging the market supply or artificially maintaining
    28
    demand by means of misstatements and misrepresentations about the health effects of
    smoking. Further, a defendant in a class action case is entitled to be protected against
    later suits by plaintiffs who failed to opt out of the class and who later assert claims
    identified in the class certification order and notice to the prospective class members.
    Our conclusion on the breadth of Plaintiff's claim is not altered by the discovery
    proceedings both prior to and after the class was certified in this case.
    Despite Plaintiffs' insistence to the contrary, the breadth that Plaintiffs now
    attribute to their claim was never specifically recognized by the district court during the
    decade of litigation that led to this appeal. After 9 years of litigation, Judge Tom R. Smith
    retired and ultimately Senior Judge Jack A. Murphy was assigned to this case and made
    the rulings now subject to appeal. Plaintiffs contend that Judge Smith held they had
    always stated the much broader claim of an international restraint-of-trade conspiracy and
    that he repeatedly "rejected" Defendants' attempts to limit Plaintiffs' claim to a domestic
    price-fixing conspiracy. Plaintiffs have cited to various points in the record where they
    argued before Judge Smith that their claim was much broader than a wholesale price-
    fixing conspiracy. But Plaintiffs fail to cite where in the record Judge Smith ever ruled, as
    they suggest, that their claim was indeed substantially broader. Defendants tell us this is
    because he never did.
    Indeed, in our close, independent review of the vast record of Judge Smith's oral
    and written rulings over the years on Plaintiffs' various discovery motions, we did not
    find that Judge Smith ever explicitly ruled that Plaintiffs stated a claim broader than the
    wholesale price-fixing claim identified in the class notice. Rather, in granting Plaintiffs'
    motions to compel, Judge Smith either overruled Defendants' privilege objections or
    found the documents were minimally relevant because they mentioned price and,
    therefore, were discoverable. That those documents also reflect conduct relevant to
    Plaintiffs' arguments that they have always stated a broader claim does not, by
    29
    implication alone, mean that Judge Smith agreed or ruled they had, indeed, stated a claim
    for anything other than wholesale price-fixing.
    Defendants eventually shifted the focus of their ongoing objections to objections
    based on claims of privilege. Disputes over these objections—particularly whether the
    joint-defense privilege is recognized under Kansas law—prompted Judge Smith's
    appointment of Judge Paul Buchanan as a special master. Plaintiffs suggested to Judge
    Buchanan that their claims mirrored those in the RICO case, so they argued the crime-
    fraud exception to the attorney-client privilege that was applied in the RICO case applied
    here as well. But Judge Buchanan rejected Plaintiffs' attempts to equate their case to the
    RICO case, stating: "This is an anti-trust price fixing case, and therefore the crime fraud
    found in [the RICO] case does not apply to this case." And Judge Smith subsequently
    overruled Plaintiffs' objections to this conclusion.
    Plaintiffs suggest on appeal that they justifiably relied upon Judge Smith's ruling
    that they had, indeed, stated the broader claim to formulate their litigation strategy and to
    now hold otherwise would somehow be inequitable. They argue that "[i]n reliance on
    [Judge Smith's] repeated rulings," they retained experts and otherwise prepared to litigate
    their more broad claims of "restraints of trade resulting from the price and non-price
    conspiracy which adversely effected [sic] price directly as well as indirectly by supply
    restriction and demand enhancement." Their argument continues: "In further reliance
    thereon," the class did not amend their pleading to provide more detail on their theory of
    the case.
    Plaintiffs cite no authority in support of their suggestion that they can be excused
    on equitable principles of justifiable reliance for taking or not taking certain procedural
    steps in the course of their litigation based on their perception of the district court's
    rulings. Accordingly, we hold that they have waived any reliance argument. See State v.
    Berriozabal, 
    291 Kan. 568
    , 594, 
    243 P.3d 352
     (2010) (holding failure to support
    30
    argument with pertinent authority or to show why argument is sound despite lack of
    supporting authority or in face of contrary authority is akin to failing to brief issue,
    meaning it is deemed waived and abandoned).
    To the extent the parties suggest that we should apply principles of the common-
    law doctrine of judicial estoppel here, we do not find the circumstances of this case call
    on us to exercise our discretion to apply that doctrine. See State v. Hargrove, 
    48 Kan. App. 2d 522
    , 548-549, 
    293 P.3d 787
     (2013) (citing New Hampshire v. Maine, 
    532 U.S. 742
    , 749, 
    121 S. Ct. 1808
    , 
    149 L. Ed. 2d 968

    , 
    147 L. Ed. 2d 164
     [2000], in discussing common-law
    doctrine of judicial estoppel).
    In sum, we conclude that Plaintiffs' claim against Defendants has always been
    solely based on wholesale price-fixing. Thus, we proceed to determine the propriety of
    summary judgment for Defendants on that claim.
    PROPRIETY OF SUMMARY JUDGMENT
    Defendants jointly insist they are entitled to summary judgment in this case just as
    they were on the same claim in other jurisdictions. Two Defendants, PMI and BATCo,
    separately contend they are entitled to summary judgment for the additional reason that
    they never engaged in activities in Kansas so as to subject them to the KRTA.
    In the three other cases involving this same price-fixing conspiracy, the courts
    found summary judgment was proper because plaintiffs failed to come forward with
    either direct evidence of a wholesale price-fixing conspiracy or sufficient circumstantial
    evidence from which a factfinder could reasonably infer such a conspiracy; that is, the
    circumstantial evidence upon which plaintiffs relied was inadequate to establish a
    reasonable inference of a price-fixing conspiracy. See Williamson Oil Co., Inc. v. Philip
    31
    Morris USA, 
    346 F.3d 1287
    , 1319-21 (11th Cir. 2003); Romero v. Philip Morris Inc., 
    148 N.M. 713
    , 724-32,

    004035-CZ, unpublished Michigan Circuit Court opinion filed September 10, 2003, Slip
    op. at *78. Two of the courts also concluded that even if plaintiffs had come forward with
    sufficient circumstantial evidence to create a rebuttable presumption of a conspiracy, the
    tobacco companies made a prima facie case supporting summary judgment by showing
    plaintiffs' theory did not make economic sense. Williamson Oil, 
    346 F.3d at 1320-21
    ;
    Romero, 148 N.M. at 731-32.
    Surviving summary judgment in antitrust cases alleging horizontal price-fixing
    Plaintiffs respond that these other jurisdictions' decisions are inapposite because
    Kansas law differs, particularly with regard to what they must show to take their case to a
    jury. For reasons explained below, we disagree.
    As already set forth at the outset of our opinion, summary judgment is appropriate
    under Kansas law if the pleadings, depositions, answers to interrogatories, and
    admissions on file, together with the affidavits, show that there is no genuine issue as to
    any material fact and that the movant is entitled to judgment as a matter of law. We
    resolve all facts and inferences that may reasonably be drawn from the evidence in favor
    of the nonmoving party and must deny summary judgment if reasonable minds could
    differ as to the conclusions drawn from the evidence. See O'Brien v. Leegin Creative
    Leather Products, Inc., 
    294 Kan. 318
    , 330, 
    277 P.3d 1062
     (2012) (O'Brien I). The
    question is whether these standards, alone, mandate a different result than that reached in
    the federal MDL and the New Mexico and Michigan state proceedings.
    In assessing the propriety of the summary judgment motions filed by the tobacco
    companies in the other jurisdictions, each court's focus was two-fold: (1) what
    constitutes a reasonable inference in this antitrust context, and (2) what facts are material
    32
    to plaintiffs' claim of a horizontal price-fixing conspiracy. See, e.g., Romero, 148 N.M. at
    720-21.
    The substantive law applied in these other cases takes into account important
    economic considerations that arise in antitrust cases in which claims of horizontal price-
    fixing in an oligopoly are supported only by circumstantial evidence of parallel pricing.
    There is no dispute that the tobacco industry, which involves five companies that
    manufacture more than 97% of cigarettes sold in the United States, is an oligopoly. See
    Williamson Oil, 
    346 F.3d at 1291
    ; Romero, 148 N.M. at 725.
    In particular, the other cases focused on the practice of competitors engaging in
    conscious parallelism. Kansas courts have not yet discussed this practice. But as
    explained by the Third Circuit in In re Baby Food Antitrust, 
    166 F.3d 112
    , 121-22 (3d
    Cir. 1999):
    "Conscious parallelism, sometimes called oligopolistic price coordination, is described as
    the process 'not in itself unlawful, by which firms in a concentrated market might in
    effect share monopoly power, setting their prices at a prefixed maximizing,
    supracompetitive level by recognizing their shared economic interests and their
    interdependence with respect to price and output decisions.' Brooke Group v. Brown &
    Williamson Tobacco Corporation, 
    509 U.S. 209
    , 227, 
    113 S. Ct. 2578
    , 
    125 L. Ed. 2d 168
    (1993). The theory of conscious parallelism is that uniform conduct of pricing by
    competitors permits a court to infer the existence of a conspiracy between those
    competitors. [Citation omitted.] The theory is generally applied to highly concentrated
    markets where few sellers exist and where they establish their prices, not by express
    agreement, but rather in a consciously parallel fashion. [Citation omitted.] Thus, when
    two or more competitors in such a market act separately but in parallel fashion in their
    pricing decisions, this may provide probative evidence of the existence of an
    understanding by the competitors to fix prices. [Citation omitted.]
    33
    "In an oligopolistic market, meaning a market where there are few sellers,
    interdependent parallelism can be a necessary fact of life but be the result of independent
    pricing decisions.
    "'[I]n a market served by three large companies, each firm must know
    that if it reduces its price and increases its sales at the expense of its
    rivals, they will notice the sales loss, identify the cause, and probably
    respond. In short, each firm is aware of its impact upon the others.
    Though each may independently decide upon its own course of action,
    any rational decision must take into account the anticipated reaction of
    the other two firms. Whenever rational decision-making requires an
    estimate of the impact of any decision on the remaining firms and an
    estimate of their response, decisions are said to be "interdependent."
    Because of their mutual awareness, oligopolists' decisions may be
    interdependent although arrived at independently.'
    Areeda, Antitrust Law § 1429 (1986). [Citation omitted.]
    "Because the evidence of conscious parallelism is circumstantial in nature, courts
    are concerned that they do not punish unilateral, independent conduct of competitors.
    Matsushita Elec. Industrial Co. v. Zenith Radio Corp., 
    475 U.S. 574
    , 594, 
    106 S. Ct. 1348
    , 
    89 L. Ed. 2d 538
     (1986). They therefore require that evidence of a defendant's
    parallel pricing be supplemented with 'plus factors.' [Citation omitted.] The simple term
    'plus factors' refers to 'the additional facts or factors required to be proved as a
    prerequisite to finding that parallel action amounts to a conspiracy.' Areeda, Antitrust
    Law § 1433(e). They are necessary conditions for the conspiracy inference. [Citation
    omitted]; Areeda, § 1434. They show that the allegedly wrongful conduct of the defense
    was conscious and not the result of independent business decisions of the competitors.
    The plus factors may include, and often do, evidence demonstrating that the defendants:
    (1) acted contrary to their economic interests, and (2) were motivated to enter into a price
    fixing conspiracy. [Citation omitted.]" (Emphasis added.)
    The Eleventh Circuit Court of Appeals further explained the purpose for this "summary
    judgment formulation . . . employed in price fixing cases" as follows:
    34
    "More frequently, price fixing plaintiffs are relegated to relying on indirect
    means of proof. The problem with this reliance on circumstantial evidence, however, is
    that such evidence is by its nature ambiguous, and necessarily requires the drawing of
    one or more inferences in order to substantiate claims of illegal conspiracy. Over time,
    courts have become attuned to the economic costs associated with using circumstantial
    evidence to distinguish between altogether lawful, independent, consciously parallel
    decision-making within an oligopoly on the one hand, and illegal, collusive price fixing
    on the other. See, e.g., Matsushita Elec. Indus. Co. v. Zenith Radio Corp., 
    475 U.S. 574
    ,
    594, 
    106 S. Ct. 1348
    , 1360, 
    89 L. Ed. 2d 538
     (1986) ('[M]istaken inferences in cases such
    as this one are especially costly, because they chill the very conduct the antitrust laws are
    designed to protect. "[W]e must be concerned lest a rule or precedent that authorizes a
    search for a particular type of undesirable pricing behavior end up by discouraging
    legitimate price competition."' (citing Monsanto Co. v. Spray-Rite Serv. Corp., 
    465 U.S. 752

     (1984) and quoting Barry Wright
    Corp. v. ITT Grinnell Corp., 
    724 F.2d 227
    , 234 (1st Cir.1983)))." Williamson Oil, 
    346 F.3d at 1300
    .
    With these important economic considerations in mind, the other courts that have
    affirmed summary judgment for the tobacco companies on a wholesale price-fixing claim
    brought under those jurisdictions' antitrust laws applied the following summary judgment
    formulation:
    "'To survive a motion for summary judgment . . . a plaintiff seeking damages for
    [collusive price fixing based on ambiguous circumstantial evidence] . . . must present
    evidence "that tends to exclude the possibility" that the alleged conspirators acted
    independently[—i.e., "plus factors"].' Matsushita, 
    475 U.S. at 588
    , 
    106 S. Ct. at 1356
    (quoting Monsanto, 
    465 U.S. at 764
    , 
    104 S. Ct. at 1471
    )." Williamson Oil, 
    346 F.3d at 1300
    .
    Plaintiffs complain this standard conflicts with the standards we must apply under
    Kansas law. Their complaint focuses in large part on the Eleventh Circuit's explanation
    that "the existence of 'plus factors' . . . remove [a plaintiff's] evidence from the realm of
    35
    equipoise and render that evidence more probative of conspiracy than of conscious
    parallelism. [Citations omitted.]" Williamson Oil, 
    346 F.3d at 1301
    . According to
    Plaintiffs, the notion that a "plus factor" must be shown to withstand summary judgment
    conflicts with the following principles of Kansas law:
     Summary judgment cannot lie when equal inferences arise from circumstantial
    evidence for and against an element of a plaintiff's cause of action.
     A court must resolve all facts and inferences which may reasonably be drawn from
    the evidence in favor of the party against whom summary judgment is sought.
     Circumstantial evidence can serve as proof of the elements of a theory of liability
    even though other reasonable theories are not excluded by such evidence.
    In a somewhat analogous situation, our Supreme Court in O'Brien I addressed the
    concept obliquely when considering evidence to support a claim of vertical price-fixing.
    In O'Brien I, the plaintiffs, a class of consumers of handbags, accessories, and luggage,
    contended that Brighton, the defendant manufacturer, adopted a pricing strategy that
    resulted in illegal price-fixing under the KRTA. The case involved claims of both
    horizontal and vertical price-fixing. The case was resolved in the district court by
    summary judgment. On appeal, our Supreme Court did not reach the question of what
    evidence was needed for the plaintiffs' horizontal price-fixing claim to survive summary
    judgment because that issue was not properly before it. 294 Kan. at 351. But the court did
    consider Brighton's argument on cross-appeal that it was entitled to partial summary
    judgment with respect to the vertical price-fixing claim, which involved merchandise sold
    at certain luggage and "Heart Store" retail stores because the plaintiffs failed to come
    forward with evidence of an agreement and concerted action between Brighton and these
    retailers. 294 Kan. at 355-56.
    36
    In resolving the issue, our Supreme Court first determined that an illegal
    "arrangement" under K.S.A. 50-112 demands "something more than merely a unilateral
    pricing policy adopted by a wholesale supplier in the position of Brighton." 294 Kan. at
    356. The court then reasoned:
    "Because K.S.A. 50-112 and § 1 of the Sherman Act share the 'between persons'
    language, . . . we look to interpreting United States Supreme Court precedent for
    assistance in understanding what, short of an express agreement, qualifies as more than
    merely unilateral behavior. Has O'Brien mustered enough evidence to avoid summary
    judgment on those purchases made at Brighton retailers who were not parties to Heart
    Store or luggage store applications or agreements?
    "In Monsanto[, 
    465 U.S. at 763
    ], the Court ruled that, under § 1 of the Sherman
    Act, a price-fixing case must include 'evidence that tends to exclude the possibility of
    independent action by the manufacturer and distributor.' '[T]here must be direct or
    circumstantial evidence that reasonably tends to prove that the manufacturer and others
    had a conscious commitment to a common scheme designed to achieve an unlawful
    objective[.]' . . . The Court acknowledged that evidence of complaints about discounting
    can be probative; however, there must be additional evidence of unlawful conduct.
    [Citation omitted]." (Emphasis added.) O'Brien I, 294 Kan. at 356-57.
    After pointing out that the evidence in O'Brien I was "reminiscent of that before the
    United States Supreme Court in Monsanto Co.," our Supreme Court observed:
    "The Court ultimately stated in Monsanto Co. that it was reasonable to conclude
    that the termination of a noncomplying distributor was pursuant to a pricing agreement
    rather than unilateral pricing policy because it was 'necessary for competing distributors
    contemplating compliance with suggested prices to know that those who do not comply
    will be terminated.' [Citation omitted.] The Court decided that the plaintiff had marshaled
    enough evidence to raise a jury issue. [Citation omitted.]
    37
    "We reach a similar conclusion here. . . . This is not a case in which the plaintiff
    can show only a unilateral pricing policy or action. A genuine issue of material fact
    remains for trial . . . ." O'Brien I, 294 Kan. at 358.
    Though this conclusion in O'Brien I was not reached in the context of a claimed
    horizontal price-fixing conspiracy predicated on conscious parallelism among
    oligopolists, we find our Supreme Court's reliance on the reasoning by the United States
    Supreme Court in Monsanto Co. v. Spray-Rite Service Corp., 
    465 U.S. 752
    , 
    104 S. Ct. 1464
    , 
    79 L. Ed. 2d 775
     (1984), significant. That very same reasoning underlies the
    summary judgment formulation developed in Matsushita Elec. Industrial Co. v. Zenith
    Radio, 
    475 U.S. 574
    , 588, 
    106 S. Ct. 1348
    , 
    89 L. Ed. 2d 538
     (1986) (citing Monsanto,
    
    465 U.S. at 764
    , in concluding that to survive summary judgment, plaintiffs had to "show
    that the inference of conspiracy is reasonable in light of the competing inferences of
    independent action or collusive action that could not have harmed" them). In short,
    O'Brien I seems to make clear that the requirement that a plaintiff must show more than
    unilateral pricing activities in order to withstand summary judgment in a price-fixing case
    brought under the KRTA is consistent with our state standards for summary judgment.
    Granted, it is settled law in Kansas that when reasonable minds can differ as to the
    conclusions drawn from the evidence, summary judgment is inappropriate. See
    Shamberg, Johnson & Bergman, Chtd. v. Oliver, 
    289 Kan. 891
    , 900, 
    220 P.3d 333
    (2009). But the antitrust cases in the Monsanto line make clear that reasonable minds
    cannot infer that price-fixing is afoot merely from conscious parallel pricing conduct of
    oligopolists. Something more must be shown to establish a reasonable inference that
    such competitors acted in concert. Reasonable minds could not draw a reasonable
    inference of price-fixing from evidence of conscious parallel pricing in an oligopolistic
    market with nothing more. As noted earlier in the court's discussion of conscious
    parallelism in In re Baby Food Antitrust, in a market served by a few large firms,
    38
    "'each firm must know that if it reduces its price and increases its sales at the expense of
    its rivals, they will notice the sales loss, identify the cause, and probably respond. In
    short, each firm is aware of its impact upon the others. Though each may independently
    decide upon its own course of action, any rational decision must take into account the
    anticipated reaction of the other[s] . . . . Because of their mutual awareness,' their
    'decisions may be interdependent although arrived at independently.' (6 Areeda, Antitrust
    Law [1986] ¶ 1429a, p. 175.) In such a market . . . prices may move generally upward
    across all of the firms more or less together, rising quickly and falling slowly, and may do
    so interdependently but nevertheless independently. (See [6 Areeda, Antitrust Law] ¶
    1429b, pp. 175-177.) For collusion, there must be more than interdependence." Aguilar v.
    Atlantic Richfield Co., 
    25 Cal. 4th 826
    , 864, 
    107 Cal. Rptr. 2d 841
    , 
    24 P.3d 493
     (2001).
    This is when evidence of a "plus factor" comes into play. As noted in Williamson
    Oil, 
    346 F.3d at 1310
    , courts need to
    "exercise prudence in labeling a given action as being contrary to the actor's economic
    interests, lest we be too quick to second-guess well-intentioned business judgments of all
    kinds. [Citation omitted.] Accordingly, [plaintiffs alleging illegal price-fixing in an
    oligopolistic market] must show more than that a particular action did not ultimately
    work to a manufacturer's financial advantage. Instead . . . the action must 'tend[] to
    exclude the possibility of independent action.' Thus, if a benign explanation for the action
    is equally or more plausible than a collusive explanation, the action cannot constitute a
    plus factor."
    We do not find the requirement of a "plus factor" to be inconsistent with Kansas
    law. As the federal courts have consistently explained, this standard for surviving
    summary judgment in an antitrust price-fixing case based on circumstantial evidence
    does not "introduce a special burden on plaintiffs facing summary judgment in antitrust
    cases." Eastman Kodak Co. v. Image Technical Services, Inc., 
    504 U.S. 451
    , 468, 
    112 S. Ct. 2072
    , 
    119 L. Ed. 2d 265
     (1992). Rather, "Matsushita demands only that the
    nonmoving party's inferences be reasonable in order to reach the jury, a requirement that
    was not invented, but merely articulated, in that decision." Eastman Kodak, 
    504 U.S. at
    39
    468; see Tops Markets, Inc. v. Quality Markets, Inc., 
    142 F.3d 90
    , 95 (2d Cir. 1998)
    (citing Matsushita, 
    475 U.S. at 588
    , in explaining that "[a]lthough all reasonable
    inferences are drawn in the nonmovant's favor, in an antitrust case, those inferences must
    be reasonable in light of competing inferences of acceptable conduct"); Aguilar, 
    25 Cal. 4th at 857
     (recognizing in this context that inference of unlawful conspiracy required by
    Matsushita "is reasonable if, and only if, it implies unlawful conspiracy more likely than
    permissible competition). In sum, the "plus factor" standard is simply an articulation of
    the requirement that an inference drawn from the plaintiff's circumstantial evidence
    offered to establish collusive pricing must be reasonable. As also stated in Williamson
    Oil, 
    346 F.3d at 1303
    , "[t]he 'tends to exclude . . .' standard articulated in Matsushita . . .
    simply represents an explication of [the reasonable inference] requirement; it does not
    represent a new hurdle. In other words, evidence creates the requisite reasonable
    inference of conspiracy if it 'tends to exclude the possibility that the alleged conspirators
    acted independently.'"
    We see no sound reason to stray from this accepted body of caselaw and economic
    analysis by declaring conscious parallelism with nothing more to be illegal under the
    KRTA. Without evidence of some plus factor that tends to establish Defendants' pricing
    policies were the product of an illegal price-fixing conspiracy in violation of the KRTA, a
    jury could not reasonably find for Plaintiffs.
    Thus, we conclude that to establish a material question of fact and thereby survive
    summary judgment, Plaintiffs must come forward with evidence that Defendants'
    wholesale pricing practices resulted from something more than legal conscious
    parallelism. This conclusion is based on the notion that in requiring something more than
    unilateral behavior, the KRTA does not reject what we perceive to be an economic
    proposition which has been universally applied in cases around the country: that
    conscious parallelism in pricing products in an oligopoly market is not sufficient, in and
    of itself, to establish illegal conduct. If this is so, then it is incumbent upon Plaintiffs to
    40
    present further evidence that tends to establish that synchronous conduct of Defendants is
    the product of an illegal conspiracy. Otherwise, why would one ever send to trial a case
    in which there is no evidence that, to a reasonable juror, tends to establish illegal
    conduct?
    Plus factors
    What evidence can constitute a plus factor in the context of Plaintiffs' claim here?
    While there are no bright-line rules to guide this query, the federal courts have offered
    some guidance on what may or may not be enough to constitute a plus factor. For
    example, in Williamson Oil the court stressed that "if a benign explanation for the
    [defendants'] action is equally or more plausible than a collusive explanation, the action
    cannot constitute a plus factor." 
    346 F.3d at 1310
    . Further, evidence that would require
    the jury to "engage in speculation and conjecture to such a degree as to render its finding
    'a guess or mere possibility'" does not constitute a plus factor. Holiday Wholesale
    Grocery v. Philip Morris Inc., 
    231 F. Supp. 2d 1253
    , 1271 (N.D. Ga. 2002), aff'd sub
    nom. Williamson Oil Co., Inc. v. Philip Morris USA, 
    346 F.3d 1287
     (11th Cir. 2003). On
    the other hand, "'a showing that the defendants' behavior would not be reasonable or
    explicable (i.e. not in their legitimate economic self-interest) if they were not conspiring
    to fix prices or otherwise restrain trade[]' [citation omitted]" can constitute a plus factor.
    Williamson Oil, 
    346 F.3d at 1301
    . In other words, "any showing by [a plaintiff] that
    'tend[s] to exclude the possibility of independent action' can qualify as a 'plus factor.'"
    
    346 F.3d at 1301
     (quoting City of Tuscaloosa v. Harcros Chemicals, Inc., 
    158 F.3d 548
    ,
    571 n.35 [11th Cir. 1998]); see Shulman, Proof of Conspiracy in Antitrust Cases & the
    Oligopoly Problem, 4 Sedona Conf. J. 1, 12-13 (Fall 2003) (setting forth list that
    "synthesizes [plus] factors that have received mention in cases and in law review
    articles").
    41
    Regardless, to be a viable plus factor, a plaintiff's showing must make economic
    sense to a reasonable jury. Eastman Kodak, 
    504 U.S. at 468-69
    . Thus, while it is not the
    role of a court to substitute itself for the factfinder in examining claimed plus factors at
    the summary judgment stage, the court must determine the "reasonableness of the
    inferences that c[an] be drawn from the evidence, [which are] threshold legal
    determinations that appropriately [are] made by the district court." Williamson Oil, 
    346 F.3d at 1304
    .
    With these standards in mind, we turn to consider the evidence of plus factors
    offered by Plaintiffs in this case. Because we have concluded that Plaintiffs' claim is for
    wholesale price-fixing and not separate claims for artificially propping up demand by
    conspiring on health issues and artificially suppressing supply by engaging in price-fixing
    in foreign markets, we will examine these two theories to determine whether either
    constitutes a plus factor from which a reasonable juror could conclude that Defendants'
    parallel pricing was the product of an illegal conspiracy to fix prices. Other claimed plus
    factors summarily enumerated in Plaintiffs' appellate brief are as follows:
    • Structure of the market with few competitors;
    • Meetings or communications involving high-level executives that present an
    opportunity to conspire or a high degree of interfirm communications;
    • Extensive information exchanges or the reciprocal exchange of price
    information;
    • History of collusion in the industry or among Defendants and ongoing
    conspiracies for the same or similar products;
    • Acting contrary to independent self-interest;
    42
    • Changing an established business practice that has been followed over a
    prolonged period of time; and
    • Giving pretextual reasons for actions.
    As evidence for each, Plaintiffs cite broadly to six volumes of the record containing their
    experts' reports. We will consider each asserted plus factor in turn.
    Structure of the Market: As support for their contention that the structure of the
    oligopolistic cigarette market is evidence of a plus factor, Plaintiffs direct us to In re Flat
    Glass Antitrust Litigation, 
    385 F.3d 350
     (3d Cir. 2004), in which the court relied on the
    holding in In re High Fructose Corn Syrup Antitrust Lit., 
    295 F.3d 651
    , 655 (7th Cir.
    2002). We assume Plaintiffs are referring to those courts' recognition that "'evidence that
    the structure of the market was such as to make secret price fixing feasible'" can support
    the plus factor of an existing motive by a defendant to enter into a price-fixing
    conspiracy. Flat Glass, 
    385 F.3d at 360
     (quoting High Fructose, 
    295 F.3d at 655
    ).
    Notably, however, both courts went on to recognize that this same factor "largely
    restate[s] the phenomenon of interdependence," so it "may not suffice—by [itself]—to
    defeat summary judgment on a claim of horizontal price-fixing among oligopolists." Flat
    Glass, 
    385 F.3d at 360-61
    ; see High Fructose, 
    295 F.3d at 655
    . Consequently, the court
    observed in Flat Glass, "this type of economic evidence is neither necessary nor
    sufficient to conclude that sufficient proof of an agreement exists to preclude summary
    judgment, but it is relevant and courts should as a general matter consider it." 
    385 F.3d at
    361 n.12.
    So we will consider the evidence Plaintiffs offer in this regard. In a report that
    Plaintiffs submitted with their response to Defendants' motions for summary judgment,
    Plaintiffs' expert economist, Dr. Keith Leffler, made several general observations
    concerning the oligopolistic nature of the cigarette market. For example, Dr. Leffler
    43
    opined: The cigarette market is "highly concentrated and conducive to successful
    collusive pricing." "Five companies dominated cigarette production in the U.S., and three
    of them 'account for about 90% of the market.'" Participants in the market face "very
    high" entry barriers. Thus, as reported by the Federal Trade Commission, the "'entry of
    additional firms into the market (or its prospect) is unlikely to upset the stability of a
    coordinated pricing strategy.'" Further, new entrants would be entering a cigarette market
    with declining demand and would face existing participants with "substantial excess
    capacity." Additionally, Dr. Leffler observed that "the demand for cigarettes is highly
    inelastic," meaning "consumers are not sensitive to cigarette prices" in making a buying
    decision and "there are no effective substitutes for cigarettes."
    This same or similar plus factor was rejected in the federal MDL proceedings.
    There, the Eleventh Circuit noted the tobacco industry "features a concentration of
    sellers, inelastic demand at competitive prices, high barriers to entry, a fungible product,
    principal firms selling at the same level in the chain of distribution, prices that can be
    changed quickly, [and] cooperative practices." Williamson Oil, 
    346 F.3d at 1296
    . The
    court concluded that the structure of the market did not constitute a plus factor because
    "the majority of the market characteristics on which the class focuses are simply indicia
    that the tobacco industry is an oligopoly, which is perfectly legal." 
    346 F.3d at 1317
    .
    Dr. Leffler also served as the plaintiffs' expert in the parallel litigation in New
    Mexico in Romero v. Philip Morris Inc., 
    148 N.M. 713
    , 
    242 P.3d 280
     (2010). There, the
    plaintiffs also alleged a plus factor based on the structure of the market, focusing
    primarily on "a highly concentrated market, cigarette fungibility, high barriers to entry in
    the industry, absence of close substitutes, and a history of collusion." 148 N.M. at 729.
    The New Mexico Supreme Court observed that a majority of these factors "are nothing
    more than inherent characteristics of an oligopoly and cannot tend to exclude independent
    action." 148 N.M. at 729.
    44
    We agree with the reasoning of these courts and reject the structure of the cigarette
    market as a viable plus factor here. A plus factor must be something that tips the scales
    from otherwise legal synchronous conduct among competitors in an oligopoly to a price-
    fixing conspiracy condemned by our antitrust laws. Conscious parallelism, which is
    lawful conduct, arises in markets containing these very factors which define an oligopoly.
    Thus, these factors, which describe market characteristics for legal conscious parallelism,
    cannot tip the evidentiary scale out of equipoise so as to provide evidence from which a
    reasonable factfinder could infer illegal conduct.
    Meetings of High-Level Executives; Interfirm Communications: The next plus
    factor summarily cited by Plaintiffs in their brief is "[m]eetings and/or communications
    of high-level executives presenting an opportunity to conspire and/or high degree of
    interfirm communications." As support, Plaintiffs cite two unpublished opinions without
    attaching copies of those opinions or offering any explanation for why they support this
    proposition. See Supreme Court Rule 7.04(g)(2)(C) (2013 Kan. Ct. R. Annot. 59)
    (requiring copy of unpublished opinion to be attached to any document that cites it). In
    short, Plaintiffs appear to suggest a jury could reasonably infer that Defendants conspired
    to fix prices from the mere fact that they had numerous opportunities to do so.
    This plus factor was also rejected in the federal MDL. The Eleventh Circuit noted
    that "the opportunity to fix prices without any showing that [the defendant tobacco
    companies] actually conspired does not tend to exclude the possibility that they did not
    avail themselves of such opportunity or, conversely, that they actually did conspire."
    Williamson Oil, 
    346 F. 3d at 1319
    .
    The court in Romero also rejected this plus factor. That court concluded that "the
    fact that Defendants may have met does not reasonably lead to the inference that they
    conspired to discuss price fixing. '[M]ere contacts and communications, or the mere
    opportunity to conspire, among antitrust defendants is insufficient evidence from which
    45
    to infer an anticompetitive conspiracy . . . .' [Citations omitted.]" 148 N.M. at 730-31; see
    Seagood Trading Corp. v. Jerrico, Inc., 
    924 F.2d 1555
    , 1575 (11th Cir. 1991) (same);
    Bolt v. Halifax Hosp. Medical Center, 
    891 F.2d 810
    , 827 (11th Cir. 1990) (same).
    We see no reason not to reject Plaintiffs' identical contention here for these same
    reasons.
    Reciprocal Exchange of Price Information: Plaintiffs suggest that Defendants'
    exchange of pricing information is evidence that tends to exclude independent conduct.
    Some additional factual background is required to provide context for this contention.
    Plaintiffs' summary contention here relates to the undisputed fact that
    Manufacturing Defendants exchanged shipment-to-wholesale cigarette volume data
    through a common consultant, Management Science Associates (MSA). In their joint
    statement of uncontroverted facts, Manufacturing Defendants stated that "participants in
    [their] respective wholesaler incentive programs compiled and reported to MSA
    information regarding the volume of their shipments to retailers." Defendants further
    stated that it was uncontroverted that "[p]articipants in [their] respective wholesaler
    incentive programs were not asked to provide, and as a function of their participation did
    not provide, [Manufacturing] Defendants or MSA with any information regarding pricing
    or discounts."
    In their response, Plaintiffs contended these facts were controverted because the
    exchange of sales data served as a "means of facilitating the monitoring of the conspiracy
    by all of the conspirators." But we note that in responding to requests for admissions on
    this issue, when discussing Defendants' use of MSA, Plaintiffs referred to the discussion
    in Williamson Oil on whether the exchange of sales data evidenced conduct to facilitate
    an illegal conspiracy or the lawful use of MSA to shift "the financial burden of gathering
    sales and market share data." 
    346 F.3d at 1313
    . Plaintiffs quoted Williamson Oil as
    46
    follows: "[B]oth explanations are plausible, and thus, at the most, this action by PM
    stands in equipoise; that is, it is equally consistent with collusion as with lawful
    competition, and accordingly, under Matsushita and Harcros, it cannot represent a plus
    factor." Williamson Oil, 
    346 F.3d at 1313
    .
    Competitors are entitled to collect and use information about their competitors in
    conducting their business, and consideration of competitors' prices is an important
    component of a pricing decision. See Wallace v. Bank of Bartlett, 
    55 F.3d 1166
    , 1169
    (6th Cir. 1995), cert. denied 
    516 U.S. 1047
     (1996); Aguilar, 
    25 Cal. 4th at 862-63
    . As
    Plaintiffs have apparently conceded, the use of MSA as a vehicle for exchanging
    information on sales volumes does not constitute a plus factor which assists the factfinder
    in its determination of whether Defendants' synchronous pricing was the product of an
    illegal conspiracy. Thus, Plaintiffs have not established how this exchange of information
    tends to exclude the possibility of independent pricing decisions.
    History of Collusion; Ongoing Conspiracies for Same or Similar Product: The
    next plus factor advanced by Plaintiffs concerns the Defendants' history of collusion,
    which they suggest "includes ongoing conspiracies for the same or similar product." As
    support for this contention, Plaintiffs summarily cite to two treatises: Shulman, Proof of
    Conspiracy in Antitrust Cases & the Oligopoly Problem, 4 Sedona Conf. J. at 9; and
    Posner, Antitrust Law 79 (2d ed. 2001). They also cite generally to Continental Co. v.
    Union Carbide, 
    370 U.S. 690
    , 699, 
    82 S. Ct. 1404
    , 
    8 L. Ed. 2d 777
     (1962). Without more
    analysis, we can only presume that in doing so, Plaintiffs are likely referring us to the
    general recognition in that case that "'the character and effect of a conspiracy are not to
    be judged by dismembering it and viewing its separate parts, but only by looking at it as a
    whole. [Citation omitted.]'" 
    370 U.S. at 699
    . We further surmise that the "[h]istory of
    collusion" generally referred to by Plaintiffs is tied largely to some of the same
    defendants' violations of the Sherman Act as discussed in American Tobacco Co. v.
    47
    United States, 
    328 U.S. 781
    , 
    66 S. Ct. 1125
    , 
    90 L. Ed. 1575
     (1946), which we will
    discuss below.
    This same plus factor was raised and rejected in both the federal MDL and the
    New Mexico case. Both courts noted that the plaintiffs in those cases failed to explain
    how an antitrust case from 50 years ago tended to exclude the possibility that Defendants'
    current pricing activities were the product of independent action. See Williamson Oil, 
    346 F.3d at 1317-18
    ; Romero, 148 N.M. at 730.
    From our review of Dr. Leffler's report, it does not appear that Plaintiffs'
    contention concerning the history of collusion has changed in this case. In his report, Dr.
    Leffler first directs us to the 1911 breakup of American Tobacco Company which
    resulted in 14 successor companies, including Liggett, Lorillard, RJR, and BATCo. See
    United States v. American Tobacco Co., 
    221 U.S. 106
    , 184-88, 
    31 S. Ct. 632
    , 
    55 L. Ed. 663
     (1911); see also United States v. American Tobacco Co., 
    164 F.3d 700
    , 1024-25
    (S.D.N.Y. 1908) (setting forth resulting dissolution decree). According to Dr. Leffler,
    "[t]he absence of vigorous price competition in the industry goes back to the turn of the
    century when the government 'dissolved' the Tobacco Trust by creating a highly
    concentrated industry run by the same executives that before explicitly acted to
    monopolize the industry." Of course, the antitrust violation that led to that early
    governmental action was not a conspiracy among competitors in violation of § 1 of the
    Sherman Act but rather the unlawful exercise of monopoly power in violation of § 2 of
    the Act.
    In 1944 American Tobacco, Liggett, and RJR were convicted of conspiracy in
    restraint of trade by price-fixing and other means. They were also convicted of a
    conspiracy to monopolize trade. American Tobacco Co. v. United States, 
    147 F.2d 93
    , 99,
    120 (6th Cir. 1944), aff'd 
    328 U.S. 781
    , 784, 
    66 S. Ct. 1125
    , 
    90 L. Ed. 1575
     (1946)
    (deciding limited question of whether actual exclusion of competitors is necessary to
    48
    crime of monopolization, which was one of four counts of which these defendants were
    convicted).
    In the Eleventh Circuit's opinion in the MDL, the court noted that Plaintiffs "failed
    to direct [the district court] to any precedent for holding such to be indicative of a present
    antitrust violation" and "failed to do so on appeal as well." Williamson Oil, 
    346 F.3d at 1318
    ; see Holiday Wholesale Grocery, 
    231 F. Supp. 2d at 1305
     (recognizing "[t]he law
    generally disfavors use of such 'historical' evidence. [Citations omitted.]" Similarly, the
    New Mexico Supreme Court in Romero, commenting on the 1944 Sherman Act violation
    found in American Tobacco Co., 
    147 F.2d 93
    , observed: "Plaintiffs do not explain how a
    case from more than fifty years ago is indicative of a present day price-fixing agreement,
    especially when only one of the current Defendants, RJR, was a defendant in [that] case."
    Romero, 148 N.M. at 730.
    We also note that at about the same time the conspiracy in the present case
    allegedly began, the United States Supreme Court stated in Brooke Group Ltd. v. Brown
    & Williamson Tobacco Corp., 
    509 U.S. 209
    , 213, 
    113 S. Ct. 2578
    , 
    125 L. Ed. 2d 168
    (1993): "Substantial evidence suggests that in recent decades, the industry reaped the
    benefits of prices above a competitive level, though not through unlawful conduct of the
    type that once characterized the industry."
    Plaintiffs contend the lock-step price moves of Defendants following Marlboro
    Friday in 1993 were the product of an illegal price-fixing conspiracy. Yet the 1980's and
    1990's marked a period of intense wholesale price competition in the tobacco industry as
    evidenced by the findings in Brooke and in R.J. Reynolds Tobacco Co. v. Philip Morris
    Inc., 
    199 F. Supp. 2d 362
    , 380-86 (M.D.N.C. 2002). We conclude that a reasonable
    factfinder would not reach back beyond this current period marked by competition to a
    time many decades earlier, when two of the numerous defendants in this case were found
    guilty under the Sherman Act, and infer from such a remote fact that all Defendants here
    49
    were engaged in a price-fixing conspiracy in 1993. Thus, we do not find the claimed
    history of collusion to be a viable plus factor.
    Acting Contrary to Independent Self-Interest: Plaintiffs contend that Defendants'
    wholesale pricing activities were contrary to their independent self-interests. On this
    point Dr. Leffler analyzed how RJR, followed by the other Manufacturing Defendants,
    reacted to Marlboro Friday. Dr. Leffler opined that rather than continuing to focus on
    maintaining or increasing the gap between discount and premium brands, which would
    have been in their economic self-interests, those Defendants gave into or aided PM-
    USA's consolidation of the pricing structure of cigarettes, in turn "mak[ing] collusive
    pricing easier and . . . thereby facilitat[ing] the alleged conspiracy." Dr. Leffler likewise
    opined that PM-USA's decision to cut prices was economically rational "[o]nly in
    [e]xpectation of [f]uture [p]rice increases" by means of, in part, the elimination of
    competition from the discount sector. Dr. Leffler offered at least three separate
    conclusions in this regard: (1) "The economic evidence indicates that it is highly unlikely
    that independent competitive behavior explains the reestablishment and maintenance of
    high cigarette[] prices after November 1993." (2) "The economic evidence indicates that
    the price increases for cigarettes after November 1993 were consistent with effective
    collusion among the cigarette producers." (Emphasis added.) (3) "The changes in market
    shares in the industry after November 1993 are consistent with an effective conspiracy to
    maintain the high average prices of cigarettes by substantially eliminating price
    competition between premium and discount cigarettes." (Emphasis added.)
    There is no dispute that evidence of actions contrary to economic self-interest can
    serve as a plus factor. Williamson Oil, 
    346 F.3d at 1310
    . But as the Eleventh Circuit
    observed, courts necessarily "must exercise prudence in labeling a given action as being
    contrary to the actor's economic interests, lest we be too quick to second-guess well-
    intentioned business judgments of all kinds." 
    346 F.3d at 1310
    . Thus, to establish this
    plus factor, it is not enough for a plaintiff to show that a particular action did not, in
    50
    hindsight, ultimately work to a defendant's financial advantage. Nor is it enough to say
    something other than self-interest might have motivated the pricing decision. Rather, "in
    the terms employed by Matsushita, the action must 'tend[] to exclude the possibility of
    independent action.' Thus, if a benign explanation for the action is equally or more
    plausible than a collusive explanation, the action cannot constitute a plus factor."
    Williamson Oil, 
    346 F.3d at 1310
    .
    Here, as we understand was also the case in the federal MDL, Plaintiffs' expert
    questioned the economic sensibility of (1) the noninitiating Defendants following price
    increases, (2) Defendants involved in the discount segment of the market deciding not to
    continue to develop that market, (3) Defendants exchanging information through the
    MSA, and (4) Defendants making payment and market-allocation decisions as part of the
    settlements of certain tort cases in 1997. See 
    346 F.3d at 1310
    .
    But the undisputed facts set forth by Defendants demonstrate that these actions
    were just as likely to be the result of independent decisions made in the economic
    interests of the individual Defendants. For example, Defendants heavily involved in the
    discount segment of the market learned from PM-USA's aggressive and unambiguous
    message that any further attempts by them to maintain or continue their attempts to widen
    the premium-discount price gap was not likely to lead to increased market gains or
    profits. Rather, Manufacturing Defendants' "only viable route back to profitability was to
    increase prices; that they did so in a parallel manner does not establish collusion." 
    346 F.3d at 1311
    .
    In short, while Plaintiffs in this case did come forward with expert opinions of
    possible collusive purposes for Defendants' pricing decisions, as was the case in the
    MDL, they did not come forward with evidence that tends to show those decisions were
    the result of collusion as opposed to independent and legal self-interested business
    51
    judgments. This is not enough to establish a plus factor sufficient to survive summary
    judgment in a price-fixing claim involving competitors in an oligopoly.
    Giving Pretextual Reasons for Actions: While Plaintiffs list this as a plus factor,
    they do not explain the "pretextual reasons" upon which they rely or how any such
    reasons tend to establish that Defendants' synchronous pricing was a product of an illegal
    conspiracy rather than lawful conscious parallelism.
    The only discussion we find to be possibly tied to this factor appears in the expert
    opinion of Dr. Jeffrey Harris. Dr. Harris opined that Defendants' public denials of the
    health hazards of smoking and the private acknowledgment of the dangers of smoking
    "points to a collusive arrangement." According to Dr. Harris, "any single company's
    denial of causation would likely lose credibility if the other oligopolistic cigarette
    manufacturers admitted that smoking causes disease. Thus, the strategic decision to deny
    that smoking causes disease benefits any individual oligopolist only if the others act
    cooperatively to deny causation as well." Dr. Harris also opined:
    "A principal motive for manufacturers' joint denial that smoking causes disease is to
    bolster cigarette consumption and thus raise industry profits. However, there were other
    industry-wide benefits of joint denial. Starting in the early 1950's, individual smokers
    began to bring lawsuits against companies. Uniform denial that smoking caused disease
    would help to insulate all defendant manufacturers from adverse judgments in such
    smokers' lawsuits. However, if one company made an admission that smoking caused
    disease, such an admission could hurt the others' chances of a successful defense in
    court."
    We find no other possible evidence relating to this claimed plus factor. Because
    this evidence relates to the claim that Defendants' conspiracy to keep hidden the adverse
    health effects of smoking constitutes a plus factor, we will address this claim in that
    context.
    52
    Foreign Price-Fixing Conspiracy: Plaintiffs argue Defendants conspired to fix the
    prices of cigarettes in foreign countries, which, in turn, drove up cigarette prices in the
    United States. Plaintiffs contend this is because the foreign price-fixing diverted
    cigarettes from the domestic market, resulting in a decreased domestic supply of
    cigarettes which artificially propped up domestic wholesale prices. Plaintiffs contend this
    foreign price-fixing scheme constitutes a plus factor that supports the notion that
    Defendants' conscious parallelism in establishing their wholesale cigarette prices was not
    merely the natural and wholly legal interdependent but independent pricing practices that
    occur in an oligopoly, but rather it was the product of an illegal agreement to fix the
    domestic wholesale price of cigarettes.
    Plaintiffs rely on the expert opinion of Dr. Leffler. According to Dr. Leffler,
    Defendants conspired to fix the prices of cigarettes outside the United States, including in
    "Canada, Europe, and numerous Latin American countries." He contends that foreign
    conspiracies encourage suppliers to export cigarettes to the more lucrative foreign
    markets. Then, "as cigarettes are sent out of the United States, reducing U.S. supply, the
    prices in the United States are expected to increase."
    Of course, an "expected" price increase does not establish that any foreign price-
    fixing activities had an actual adverse impact on domestic cigarette prices. This is
    particularly so in light of Dr. Leffler's observation: "The market for the cigarettes has
    been declining since the 1980s, resulting in substantial excess capacity by the incumbent
    firms." See also Brooke Group, 
    509 U.S. at 214
    .
    According to the Federal Trade Commission, domestic cigarette sales for the
    period 1990 to 1999 declined from 524 billion cigarettes to 411 billion cigarettes. R.J.
    Reynolds, 
    199 F. Supp. 2d at
    367 n.3. At least one federal court has recognized as a result
    that RJR, Lorillard, and B&W "possess[ed] substantial excess capacity that would enable
    them to expand supply in order to meet any unsatisfied market demand." 
    199 F. Supp. 2d 53
    at 384. These market circumstances "tend to break down patterns of [unlawful] pricing
    and produce price competition." Brooke Group, 
    509 U.S. at 238
    .
    We find it significant that neither Plaintiffs nor any of their experts have directed
    us to any evidence (or something more than equivocal hypotheses) that any diversion of
    cigarettes to foreign markets to meet the demands of a conspiracy there was not made up
    for by additional domestic cigarette production.
    Here, Dr. Leffler's opinion goes beyond this supply/demand argument to posit that
    the foreign price-fixing "agreements in other markets aid in establishing and maintaining
    industry cooperation necessary for successful collusion." As we understand it, Dr.
    Leffler's contention is that when competitors collude in several foreign markets, if one
    conspirator "jumps ship" in one particular market, that conspirator's position in another
    market where the conspirators' enjoy inflated prices may be placed in jeopardy.
    Further, and rather curiously, Dr. Leffler contends that the existence of a domestic
    price-fixing conspiracy promotes the success of the foreign price-fixing conspiracy by
    discouraging domestic suppliers not party to the foreign conspiracy from entering the
    foreign market and undercutting the fixed price. This theory, of course, provides no
    support for the notion that the claimed foreign price-fixing conspiracy provides evidence
    from which one can infer an agreement to fix prices in Kansas. Domestic conduct that is
    alleged to have furthered a conspiracy to fix prices in some foreign market is not relevant
    in this case.
    In the federal MDL case, the defendants contended that their pricing agreements in
    foreign markets were consistent with local law. The Eleventh Circuit rejected the
    contention that evidence of foreign price-fixing conspiracies constituted a viable plus
    factor to support the proposition that the defendants' parallel pricing in the United States
    was the product of an illegal conspiracy. The Eleventh Circuit reasoned that the plaintiffs
    54
    failed to produce any evidence of any "palpable tie" between the tobacco companies'
    overseas activities and pricing actions in the United States. Williamson Oil, 
    346 F.3d at 1317
    . The court further reasoned that any such evidence would not establish a prior
    wrongful act when the plaintiffs had not shown that the tobacco companies' actions were
    unlawful under foreign law. 
    346 F.3d at 1317
    .
    Likewise, in our present case Plaintiffs have not established that any alleged price-
    fixing activities by Defendants that underlie their allegations here were, in fact, unlawful
    under foreign law. Nor have plaintiffs produced any evidence of any "palpable tie"
    between the tobacco companies' overseas activities and the pricing actions in the United
    States that underlie the price-fixing claim in this case. To the contrary, Plaintiffs' own
    expert (Dr. Leffler) recognized market circumstances that would suggest the contrary. In
    sum, even if we were to accept as true Plaintiffs' contentions that a foreign price-fixing
    conspiracy was afoot, Plaintiffs have not come forward with evidence to show such a
    conspiracy tends to establish Defendants' domestic wholesale pricing was the product of
    an unlawful conspiracy. Rather, they have given us only speculative economic theory that
    simply is not enough to survive summary judgment on a horizontal price-fixing claim
    against an oligopoly.
    Smoking and Health Conspiracy: Plaintiffs' claim regarding a smoking and health
    conspiracy mirrors the claim raised in the federal MDL. See Williamson Oil, 
    346 F.3d at 1315-16
    . Accordingly, a detailed discussion of the Eleventh Circuit's treatment of that
    plus factor is in order at the outset of our consideration of this plus factor.
    The plaintiffs in Williamson Oil alleged that the tobacco companies "conspired
    during the 1950s to refrain from seeking any competitive advantage by developing more
    health-conscious tobacco products or by competing on the basis of health generally." 
    346 F.3d at 1296
    . According to the plaintiffs, this health conspiracy remained effective during
    the price-fixing conspiracy period in Williamson Oil (which essentially mirrors the
    55
    "[c]lass [p]eriod" in our case) and "evidence[d] [the defendants'] agreement to fix prices."
    
    346 F.3d at 1315
    . But Professor Franklin Fisher, the plaintiffs' expert in Williamson Oil,
    cited no conduct in furtherance of this health conspiracy during the period of the price-
    fixing conspiracy. Rather, he opined that it was "'entirely possible that [the tobacco
    companies'] decisions to limit health-based marketing in the past continued to be felt
    between 1993 and 2000. Such decisions may have checked companies' incentives to
    vigorously pursue health-related research.'" 
    346 F.3d at 1316
     (quoting Holiday Wholesale
    Grocery, 
    231 F. Supp. 2d at 1311
    ).
    The Eleventh Circuit held this evidence was too speculative to constitute a plus
    factor. Williamson Oil, 
    346 F.3d at 1316
    . As support, the court cited Eastman Kodak Co.
    v. Image Technical Services, Inc., 
    504 U.S. 451
    , 468-69, 
    112 S. Ct. 2072
    , 
    119 L. Ed. 2d 265
     (1992), for the proposition that "evidence of predatory pricing that is '"speculative"
    and [is] not "reasonable"' is insufficient to withstand an antitrust defendant's summary
    judgment motion" before concluding that an inference of misconduct cannot arise from
    mere speculation, which was all that the plaintiffs had brought before the court.
    Williamson Oil, 
    346 F.3d at 1316
    .
    In our present case, and contrary to the situation in Williamson Oil, Plaintiffs cite
    conduct during the period of the alleged price-fixing conspiracy in which tobacco
    company executives, in furtherance of the health conspiracy, testified before Congress in
    1994 that cigarette smoking is not addictive and the presence of nicotine does not make it
    so. According to Dr. Harris, this health conspiracy began to unravel in the late 1990's and
    then ended "[w]ithin a 15-day period in June 2000, [when] all of the major cigarette
    manufacturers—[PM-USA, RJR,] and Lorillard, as well as [B&W]—made an abrupt
    about-face and admitted that smoking causes disease."
    The court in Williamson Oil found the plaintiffs' evidence of a health conspiracy
    could not constitute a plus factor because
    56
    "[i]n essence, for a jury to infer from this evidence that appellees collusively
    fixed prices during the 1990s, it would have to engage in propensity reasoning, i.e., 'they
    did it 40 years before so they probably did it again,' albeit now with Lorillard on board
    and with the object of the conspiracy being prices as opposed to health." 
    346 F.3d at 1316
    .
    Similarly, under our rules of evidence, specifically K.S.A. 2013 Supp. 60-455, evidence
    of this health conspiracy may not be admitted "as the basis for an inference that
    [Defendants] committed another crime or civil wrong on another specified occasion." But
    such evidence may be admitted "when relevant to prove some other material fact
    including motive, opportunity, intent, preparation, plan, knowledge, identity or absence
    of mistake or accident." K.S.A. 2013 Supp. 60-455. Further, this is not an exclusive list.
    "[T]hese eight are among the possibilities, not the only possibilities." State v. Gunby, 
    282 Kan. 39
    , 53, 
    144 P.3d 647
     (2006). To be admitted under K.S.A. 2013 Supp. 60-455, the
    evidence must be relevant. K.S.A. 60-401(b) defines relevant evidence as "evidence
    having any tendency in reason to prove any material fact."
    The district court opinion in the RICO case demonstrates ample—in fact,
    overwhelming—evidence of a conspiracy to hide from the public the deleterious effects
    of smoking. There is also evidence to support the argument that this conduct had the
    effect of artificially maintaining the demand for cigarettes at a level higher than would
    have been the case (at least for some period of time) had the public known and
    understood the dangers of smoking. The court held the defendants violated RICO by
    marketing and selling "their lethal product with zeal, with deception, with a single-
    minded focus on their financial success, and without regard for the human tragedy or
    social costs that success exacted." United States v. Philip Morris USA, Inc., 
    449 F. Supp. 2d 1
    , 28 (D.D.C. 2006), aff'd in part and vacated in part by 
    566 F.3d 1095
     (D.C. Cir.
    2009), cert. denied 
    130 S. Ct. 3502
    , reh. denied 
    131 S. Ct. 57
     (2010). The court
    determined that defendants' nonprice agreements "were calculated to serve their shared
    57
    objectives, including their primary goal of maximizing profits by preserving and
    expanding the market for cigarettes." 
    449 F. Supp. 2d at 872
    .
    In our present case, Dr. Leffler stated:
    "By suppressing competition on health related product differentiation, defendants would
    directly impact the price of cigarettes. As consumers became more aware of the health
    risks of smoking, demand for cigarettes would be reduced and price would fall. By
    collusively controlling the industry reaction to the emerging literature on the health
    impacts of smoking and by controlling efforts to produce a safer cigarette the industry
    would directly impact the prices paid for cigarettes by Kansas consumers."
    Dr. Harris expressed similar views. Another expert for Plaintiffs, Dr. Aju J. Fenn opined:
    "Cigarette demand with no information or misleading information about addiction will be
    higher than the demand for cigarettes of a fully informed consumer. Consumer[s] who
    start consuming cigarettes without the explicit knowledge that they are addictive falsely
    believe that they have a choice to stop consuming the product at any time. They are
    unaware that their current actions are committing them to future purchases of cigarettes.
    If properly informed about the addictive nature of cigarettes, coupled with the
    information of the adverse health effects of smoking many of these consumers would
    choose not to smoke. This is clearly evident from the drops in cigarette consumption
    during the years that the Surgeon General's warnings were issued. However, these health
    warnings lose their effectiveness over time given the barrage of misleading information
    and the constant stream of denials about the adverse health effects and addictive nature of
    cigarettes by the defendants."
    But the question for us is whether the existence of such a conspiracy constitutes
    circumstantial evidence which tends to prove to a reasonable person that the synchronous
    wholesale pricing of cigarettes in this oligopoly market was the product of an illegal
    agreement to fix prices rather than legal conscious parallelism. In other words, does
    evidence of the existence of this health conspiracy, which had the effect of artificially
    58
    maintaining demand for tobacco products, tend to prove that Defendants entered into a
    separate conspiracy to fix the wholesale prices for cigarettes sold in Kansas?
    There must be a rational connection between the evidence of the health conspiracy
    and the contention that Defendants entered into a separate price-fixing conspiracy.
    Plaintiffs allege the health conspiracy began in December 1953. This conspiracy
    apparently ended in June 2000 when the tobacco manufacturers admitted the health risks
    associated with smoking. Plaintiffs contend this conspiracy was effective in propping up
    demand for cigarettes and enhancing the profitability of the tobacco industry. In the
    meantime, the price-fixing conspiracy at issue here is alleged to have begun in November
    1993, after the health conspiracy had been in operation for 40 years. We find no evidence
    that would explain why, in the midst of an apparently successful health conspiracy,
    Defendants would overlay that conspiracy with a separate price-fixing conspiracy.
    Further, unlike the profitable health conspiracy, the price-fixing conspiracy the
    Defendants are accused of entering into was one during which cigarette prices were lower
    than they had been before the claimed conspiracy began. Cigarette prices ultimately
    increased during the claimed conspiracy at a rate lower than before. The claimed
    coconspirators spent far more competing with one another (over $25 billion) than the
    amount of the overcharge in wholesale prices ($11.9 billion) claimed in the MDL. The
    level of competition led RJR and B&W to sue Philip Morris for antitrust violations in the
    midst of the alleged conspiracy.
    The tobacco manufacturers apparently hung together to the bitter end in carrying
    out the health conspiracy. Yet in the price-fixing conspiracy that allegedly arose after 40
    years of hiding the facts about the health effects of tobacco, competition among the
    claimed coconspirators resulted in dramatic shifts in market share, rendering some of
    them winners and others clear losers. All of this leads us to conclude that the existence of
    the health conspiracy does not have a tendency in reason to prove that Defendants also
    59
    engaged in the alleged price-fixing conspiracy. The health conspiracy does not constitute
    a plus factor.
    Taken individually or collectively, the structure of the market, the meetings
    between tobacco company executives, the exchange of sales information, the history of
    past misconduct, the actions claimed to be contrary to the actors' independent self-
    interest, the claimed pretextual reasons for actions, the foreign price-fixing claim, and the
    health conspiracy do not constitute evidence that tends to exclude the possibility that
    Defendants were engaged in lawful conscious parallelism in their pricing decisions. With
    that, we conclude the district court did not err in granting summary judgment to
    Defendants.
    In light of this holding, we need not consider Plaintiffs' challenge to the district
    court's alternative basis for granting summary judgment in favor of Defendants PMI and
    BATCo based upon the lack of evidence that they sold product in Kansas. Even if we
    were to agree with Plaintiffs' criticism of the district court's ruling regarding PMI and
    BATCo, they would still be entitled to summary judgment on Plaintiffs' wholesale price-
    fixing claim for the same reasons as the other Defendants.
    DENIAL OF PLAINTIFFS' MOTION TO FILE SECOND AMENDED PETITION
    Plaintiffs also contend that even if we do not reverse the summary judgment
    entered in Defendants' favor, we should find error in the district court's denial of their
    motion for leave to file a second amended petition.
    Standard of review
    We review the district court's denial of Plaintiffs' motion to amend their first
    amended petition under K.S.A. 2013 Supp. 60-215 for any abuse of judicial discretion.
    60
    See Johnson v. Board of Pratt County Comm'rs, 
    259 Kan. 305
    , Syl. ¶ 14, 
    913 P.2d 119
    (1996). We will declare the district court's decision an abuse of discretion only if
    Plaintiffs demonstrate it is: (1) arbitrary, fanciful, or unreasonable; (2) based on an error
    of law; or (3) based on an error of fact. See Critchfield Physical Therapy v. The Taranto
    Group, Inc., 
    293 Kan. 285
    , 292, 
    263 P.3d 767
     (2011) (means of abuse of discretion);
    Harsch v. Miller, 
    288 Kan. 280
    , 293, 
    200 P.3d 467
     (2009) (burden of proof).
    Governing principles
    Our Supreme Court has recognized at least five valid justifications for denying a
    motion to amend a pleading despite our broad notice-pleading principles discussed above.
    They include: (1) undue delay, (2) bad faith or dilatory motive on the part of the movant,
    (3) repeated failure to cure deficiencies by amendments previously allowed, (4) undue
    prejudice to the opposing party by virtue of allowance of the amendment, and (5) futility
    of amendment. Johnson, 259 Kan. at 327 (quoting Foman v. Davis, 
    371 U.S. 178
    , 182, 
    83 S. Ct. 227
    , 
    9 L. Ed. 2d 222
     [1962]). In denying Plaintiffs' motion to amend, the district
    court found all of these justifications applicable except the third.
    Before reviewing that decision for any abuse of discretion, some additional factual
    background is necessary. Plaintiffs moved to file a second amended petition on
    December 21, 2011—more than 10 years after they filed their first amended petition.
    Their motion followed on the heels of Judge Murphy's ruling that Plaintiffs had raised but
    a single claim for a wholesale price-fixing conspiracy. In support of their motion,
    Plaintiffs first argued below, as they do on appeal, that their motion to amend was little
    more than "a 'belts and suspenders' move" necessary only to "even more clearly define its
    non-price allegations" or provide "a better pleaded claim."
    If, in fact, the second amended petition did not materially alter Plaintiffs' claim,
    then they can hardly claim prejudice from the court's denial of their motion. But for the
    61
    reasons discussed earlier in defining the scope of Plaintiffs' claim for summary judgment
    purposes, we reject Plaintiffs' position that this was nothing more than a clarification of
    claims already raised in their first amended petition. Rather, we conclude Plaintiffs'
    motion to amend was an attempt to state new and different claims.
    But Plaintiffs contend the district court abused its discretion by failing to provide
    "any reasoning at all" in support of its denial of their motion to amend. We find no
    support for this contention. The district court adopted the reasons advanced by
    Defendants in their opposition to the motion: undue delay would result, the class had
    shown bad faith or a dilatory motive, Defendants would be prejudiced, and the
    amendment would be futile.
    Defendants point out that Plaintiffs moved to file their second amended petition 12
    years after the case was filed, more than 10 years after the class was certified, 6 years
    after discovery was closed, and less than 1 month before the hearing on Defendants'
    summary judgment motions. Amending Plaintiffs' petition to assert new causes of action
    would have materially altered the course of the case and its final resolution. It would have
    required the court to revisit the class certification issue and, at a minimum, provide new
    notice to members of the class regarding these new claims. For these reasons alone, we
    find no abuse of discretion in the district court's ruling. Thus, we need not address the
    other reasons expressed by the district court.
    DENIAL OF PLAINTIFFS' MOTION FOR DEFAULT JUDGMENT
    Plaintiffs' final issue on appeal concerns the denial of their motion for default
    judgment on three motions for partial summary judgment they filed. Before we can
    address their argument, more background is necessary.
    62
    At the same time Plaintiffs filed their joint response to Defendants' various
    motions for summary judgment, Plaintiffs filed their own three motions for partial
    summary judgment. Defendants responded with a joint motion to defer briefing on those
    motions. In support, Defendants pointed out that Plaintiffs' summary judgment motions
    were all based on the argument that Plaintiffs had stated something more than a price-
    fixing claim, and any such argument would be moot if the district court granted
    Defendants' motions for summary judgment, which were based on the premise that
    Plaintiffs stated only a price-fixing claim. Plaintiffs responded with a motion for default
    judgment, arguing that Defendants had not properly responded to Plaintiffs' summary
    judgment motions.
    Following a hearing in October 2011, the district court denied Plaintiffs' motion
    for default and granted Defendants' motion to defer briefing on Plaintiffs' summary
    judgment motions. While the district court agreed with Plaintiffs' position that the
    Defendants' motion to defer did not necessarily fall within the parameters of a response to
    a motion for summary judgment anticipated under K.S.A. 2013 Supp. 60-256(f), the
    district judge found:
    "I think in this case and in these circumstances, where continuances have been granted to
    all of the parties over this 10, 12-year period, I'm not going to find that default judgment
    is appropriate. I think that the motion to defer served as a response, maybe not albeit
    perfect, but I think it is a response that takes it out of the default arena."
    Plaintiffs contend here that this was error. Defendants respond that the court was well
    within its discretion to deny the motion for default judgment.
    63
    Standard of review
    We review the district court's decision on a motion for default judgment for an
    abuse of discretion. See Bazine State Bank v. Pawnee Prod. Serv., Inc., 
    245 Kan. 490
    ,
    Syl. ¶ 1, 
    781 P.2d 1077
     (1989), cert. denied 
    495 U.S. 932
     (1990); Lara v. Vasquez, 
    33 Kan. App. 2d 128
    , 130-31, 
    98 P.3d 660
     (2004), rev. denied 
    279 Kan. 1006
     (2005).
    Plaintiffs contend the district court abused its discretion because the denial of their
    motion for a default judgment was premised on an error of law. They argue that "there is
    no such thing as a motion to defer"; and, if Defendants' motion was meant to be a motion
    to continue, their response had to be accompanied by the statutorily required K.S.A. 2013
    Supp. 60-256(f) affidavit.
    Defendants initially respond that the class' argument is based on two faulty
    premises: (1) that Plaintiffs' motions for summary judgment were procedurally proper in
    the first place; and (2) that Defendants failed to respond.
    Defendants further point out that even if they failed to respond, the summary
    judgment sought by the class for $7.58 billion was inappropriate in this case. We agree.
    Given our holding that Plaintiffs' lawsuit was not based on the "non-price" claims that
    underlie their motions for summary judgment, default partial summary judgments on
    those claims would not have been appropriate. See K.S.A. 2013 Supp. 60-256(e)(2)
    (when opposing party fails to respond to motion for summary judgment, summary
    judgment should, if appropriate, be entered against that party).
    Motions for default judgment are not favored in the law. Bazine State Bank, 
    245 Kan. at 495
    . We find no abuse of discretion in the district court's denial of Plaintiffs'
    motion for a default judgment on their motions for partial summary judgment. Further,
    64
    given our decision upholding summary judgment for Defendants, these motions are now
    moot.
    We need not consider Defendants' contingent cross-appeals from the class
    certification order and the order compelling the production of documents because these
    issues are now moot.
    Affirmed; cross-appeals dismissed.
