    BACKGROUND
    A. Facts
    1. The Supply Agreement
    In 1992, Amoco Chemical Company, a subsidiary of
    Amoco Corporation, outsourced the production of its
    polypropylene catalyst, known as “CD-Catalyst,” to
    Catalyst Resources, Inc. (“CRI”), a company owned by
    Phillips Petroleum Company (“Phillips”). The agreement
    reached between Amoco Chemical and CRI was embodied
    in a long-term supply agreement (“Supply Agreement”).
    According to the terms of the Supply Agreement, CRI
    agreed to build a production facility in Texas, and
    Amoco Chemical agreed to pay the cost of the facility
    over the course of a ten-year period through its pur-
    chasing commitments.
    The detailed Supply Agreement is over one hundred
    pages long and includes terms for production and pricing,
    as well as more general contractual terms. The dispute
    in this case centers on the interpretation of Articles 17 and
    19 of the contract. Article 17, entitled “The Right of First
    Refusal Clause,” states in relevant part:
    17.A. During the term of this Agreement, neither CRI
    nor Phillips, which indirectly wholly owns CRI, shall
    sell, transfer, assign, grant any option with respect to,
    merge, or otherwise dispose of any of the ownership or
    control of CRI, or any part of the Plant or of the Plant
    Site, or allow any of the foregoing to occur, unless: (i)
    CRI or Phillips has received a bona fide arm’s-length
    offer to transfer the entire ownership or control of CRI,
    No. 08-1359                                                  3
    or to transfer the ownership or control of certain
    assets of CRI, which assets include but are not
    limited to the entirety of the Plant and the Plant Site, to
    such party or parties; (ii) CRI or Phillips has deter-
    mined that it is willing to accept such offer; (iii) CRI or
    Phillips has notified Amoco, in writing, of the terms
    and conditions of such offer; (iv) CRI or Phillips has
    first afforded Amoco the option to buy all of CRI or
    to buy all of the certain assets of CRI, which
    assets include but are not limited to the entirety of the
    Plant and the Plant Site, whichever is applicable, on
    terms and conditions no less favorable to Amoco than
    those contained in the offer; and (v) Amoco does not
    exercise its option to buy all of CRI or to buy all of the
    certain assets, which assets include but are not
    limited to the entirety of the Plant and the Plant Site,
    whichever is applicable, on such terms and condi-
    tions within ninety (90) days of receipt of the written
    notification referred to in (iii) above.
    R.50-2, Ex. A at 95-96. Article 17.B. goes on to state that
    the right of first refusal does not apply to transfers of
    ownership to any company wholly owned by Phillips.
    Article 17.C. provides that, in the event that Amoco fails
    to exercise its option, and CRI completes the transaction,
    the transferee in those circumstances would continue to
    be bound by the Supply Agreement, including specifically
    Article 17.A. See 
    id. at 96-97.
      Also at issue is one of the “General Provisions” of Article
    19, specifically Article 19.A., concerning “Assignment”:
    Assignment. Neither party may assign this Agree-
    ment, or any part thereof, without the prior written
    4                                                No. 08-1359
    consent of the other, except that Amoco may assign
    this Agreement in its entirety only without the
    consent of CRI at any time to an entity owned fifty
    percent (50%) or more, directly or indirectly, by
    Amoco Corporation, and CRI may assign this Agree-
    ment in its entirety only without the consent of Amoco
    to any company one hundred percent (100%) owned,
    directly or indirectly, by Phillips. Any other attempted
    assignment without the other party’s consent shall be
    void. The terms of this Agreement shall be binding
    upon and inure to the benefit of the parties hereto
    and their successors and permitted delegatees and
    assignees.
    
    Id. at 100.
    2. Corporate Changes
    Over the years since the Supply Agreement was
    entered, each party has undergone a number of corporate
    mergers, restructurings or changes in ownership, which
    are crucial to understanding the parties’ claims in this
    appeal. The corporate evolution of both parties is set
    forth below.
    In 1995, Amoco Chemical assigned its rights and duties
    under the Supply Agreement to Amoco Polymers.1 On
    December 31, 1998, Amoco Corporation, the parent of
    Amoco Chemical and indirect parent of Amoco Polymers,
    merged with a subsidiary of The British Petroleum Com-
    1
    There is no suggestion in the record that CRI objected to
    this action as an impermissible assignment under Article 19.A.
    No. 08-1359                                                  5
    pany p.l.c. (“BP”). The merged entity was renamed BP
    Amoco Corporation. Subsequent to this merger, Amoco
    Polymers was renamed BP Amoco Polymers, Inc.2
    In 2005, BP announced a corporate reorganization of
    its petrochemical and refining business. Pursuant to this
    reorganization, on March 31, 2005, the shares of BP Amoco
    Polymers were transferred to a newly formed limited
    liability company, indirectly owned by BP, called O & D
    USA LLC. On May 24, 2005, O & D USA LLC was
    renamed Innovene USA LLC, and BP Amoco Polymers
    was renamed Innovene Polymers, Inc. Later that same
    year, INEOS US Intermediate Holding Company LLC
    acquired Innovene LLC, the parent company of both
    Innovene USA LLC and Innovene Polymers. On May 31,
    2006, the entities changed their names to INEOS USA
    LLC and INEOS Polymers, Inc., respectively.
    On the CRI side of the transaction, in 1994, Mallinckrodt
    purchased CRI, including the plant and CRI’s rights and
    obligations under the Supply Agreement. By letters
    dated October 13, 1993, and December 17, 1993, Amoco
    waived its right of first refusal under Article 17 with
    respect to the purchase of CRI by Mallinckrodt. In 1998,
    another company, Engelhard purchased CRI’s assets
    from Mallinckrodt; again, Amoco Polymers waived its
    right of first refusal.3 In 1999, and again in 2005, Engelhard
    2
    The successor to CRI did not object to this merger as viola-
    tive of Article 19.A.
    3
    Specifically, the letter dated March 24, 1998, stated:
    1. Upon Amoco’s receipt of a fully executed copy of this

    entered into a sale/leaseback transaction first with Chase
    Equipment Leasing, Inc., and later with Key Corporate
    Capital, that involved assets subject to Article 17; with
    respect to both of those transactions, Amoco waived its
    right of first refusal. See R.50-2, Exs. C & D. In June 2006,
    BASF AG “announced the completion of an acquisition
    whereby Engelhard became a wholly owned subsidiary
    of BASF AG and was subsequently renamed and con-
    verted to BASF Catalysts.” R.50-2, ¶ 40.4
    The corporate evolution of the parties to the Supply
    Agreement, set forth above, are embodied in the fol-
    lowing chart:

    letter, Amoco will be deemed to have waived its rights of
    first refusal under Article 17 of the Agreement only for the
    transaction proposed in the February 23, 1998 letter of intent
    between Mallinckrodt and Engelhard (the “Letter of In-
    tent”), provided that the transaction set forth in the Letter
    of Intent is consummated by December 31, 1998. Article 17
    of the Agreement shall remain in full force and effect and
    apply to all other transfers described in Article 17 and
    shall apply to any sale or transfer by Mallinckrodt to
    Engelhard of assets covered by Article 17 if such occurs
    after December 31, 1998.
    R.50-2, Ex. B. The letter made no mention of Article 19.A.
    4
    Prior to this transaction, BASF AG, through a wholly owned
    subsidiary had attempted a hostile takeover of Engelhard.
    Specifically, it had made an all-cash proposal to acquire all
    outstanding common stock. The board of Engelhard initially
    rejected the offers and proposals of BASF AG; however, on
    May 29, 2006, the board approved a merger agreement.

    Appellant’s Br. at 12 (footnote omitted).
    When INEOS Polymers became aware of the Engelhard-
    BASF AG transaction, it informed Engelhard and BASF
    Catalysts that it believed that the change of ownership
    had triggered Article 17’s right of first refusal. BASF
    Catalysts denied that Article 17 was triggered by the
    transaction. Subsequently, BASF Catalysts discontinued
    discussions with INEOS Polymers concerning plant
    improvements unless INEOS Polymers “abandoned its
    efforts to exercise the right of first refusal.” R.50-2, ¶ 48.
    B. District Court Proceedings
    INEOS Polymers brought an action in the United States
    District Court for the Northern District of Illinois
    against BASF Catalysts and BASF AG alleging breach of
    contract and tortious interference with contractual
    rights, respectively. BASF Catalysts and BASF AG moved
    to dismiss the complaint on various grounds, one of
    which was that INEOS Polymers was an impermissible
    assignee of the Supply Agreement and, therefore, could not
    enforce the rights set forth in that agreement. The district
    court agreed and dismissed INEOS Polymers’ amended
    complaint on the ground that, as an impermissible as-
    signee, it could not maintain an action to enforce the
    contract.
    INEOS Polymers moved for reconsideration and for
    leave to file a second amended complaint; the district
    court granted the motions, but again dismissed the com-
    plaint with prejudice on the same ground. The district
    court summarized its holding accordingly:
    No. 08-1359                                                 9
    In sum, the bottom line remains that INEOS is just
    not an entity owned 50% or more, directly or indi-
    rectly, by Amoco Corporation. And that being so, it is
    not within the limited universe of permitted assignees
    that was carefully marked out by the original con-
    tracting parties when they put their deal together.
    Hence the motion to reject INEOS’ attempted enforce-
    ment of Art. 17.A is well taken. And that calls for
    dismissal not only of the [second amended complaint]
    but also of the action itself, for INEOS’ successive
    struggles to escape that result have confirmed that the
    basic defect on which this Court has elaborated at
    some length, both in Opinion I and this opinion, is
    not curable.
    R.64 at 8.5

    DISCUSSION
    As we have just noted, the sole basis on which the
    district court granted the defendants’ motion to dismiss
    was that INEOS Polymers could not enforce any rights
    under the contract. According to the district court, the
    5
    Because the district court dismissed the action on the
    ground that INEOS Polymers was an impermissible assignee,
    it did not reach the merits of INEOS Polymers’ claims, nor did
    it address any of the other arguments in support of the motion
    to dismiss made by BASF Catalysts or BASF AG. On appeal,
    neither BASF Catalysts nor BASF AG urges us to affirm the
    district court’s judgment on any other ground.
    10                                                  No. 08-1359
    corporate transactions that transformed BP Amoco Poly-
    mers into INEOS Polymers involved an assignment of
    rights under the Supply Agreement to an entity not
    “owned fifty percent (50%) or more, directly or indirectly,
    by Amoco Corporation.” Therefore, the district court
    concluded, INEOS Polymers was an impermissible as-
    signee and could not maintain an action for breach of the
    Supply Agreement vis a vis BASF Catalysts and BASF AG.
    “We review de novo a district court’s dismissal of a
    complaint for failure to state a claim. In our review, we
    must accept the allegations in the plaintiff’s complaint as
    true and draw all reasonable inferences in favor of
    the plaintiff.” Vill. of DePue, Ill. v. Exxon Mobil Corp., 
    537 F.3d 775
    , 782 (7th Cir. 2008). A complaint will withstand
    a motion to dismiss if it provides a “ ‘short and plain
    statement of the claim showing that the pleader is
    entitled to relief’ that is also sufficient to provide the
    defendant with ‘fair notice’ of the claim and its basis.”
    Windy City Metal Fabricators & Supply, Inc. v. CIT
    Technical Fin. Servs., Inc., 
    536 F.3d 663
    (7th Cir. 2008) (citing
    Bell Atl. Corp. v. Twombly, ___ U.S. ___, 
    127 S. Ct. 1955
    , 1964
    (2007); Fed. R. Civ. P. 8(a)(2)). “In order to demonstrate
    that he is entitled to relief, however, the pleader must
    show through his allegations that ‘it is plausible, rather
    than merely speculative, that he is entitled to re-
    lief.’ ” 
    Id. (quoting Tamayo
    v. Blagojevich, 
    526 F.3d 1074
    ,
    1083 (7th Cir. 2008)).
    When reviewing the dismissal of a breach of contract
    claim the meaning of the contract “must be determined
    from the words or language used, and a court cannot
    No. 08-1359                                                   11
    place a construction on the contract which is contrary
    to the plain and obvious meaning of the language.” If
    the district court determines that the contract is unam-
    biguous, it may determine its meaning as a matter of
    law. The unambiguous contract controls over con-
    trary allegations in the plaintiff’s complaint.
    McWane, Inc. v. Crow Chicago Indus., Inc., 
    224 F.3d 582
    , 584
    (7th Cir. 2000) (quoting Johnstowne Centre P’ship v. Chin, 
    458 N.E.2d 480
    , 481 (Ill. 1982); additional citations omitted).
    A. Language and Structure of the Supply Agreement
    In order to uphold the district court’s judgment dis-
    missing INEOS Polymers’ action, we must conclude that,
    based on a clear and unambiguous reading of the
    Supply Agreement, Article 19.A. requires the parties to
    obtain the other’s consent prior to any change in owner-
    ship or control. We do not believe that the language or
    structure of the contract allows us to reach that conclusion.
    First, the district court’s interpretation of Article 19.A. is
    at odds with the common meaning and use of the
    terms “assignment” and “change in corporate control.” We
    made clear in Baxter Healthcare Corp. v. O.R. Concepts, Inc.,
    
    69 F.3d 785
    (7th Cir. 1995), that these terms are not synony-
    mous. In that case, Baxter had entered into a distribu-
    tion agreement with O.R. Concepts. During the term of
    the agreement, O.R. Concepts sold ninety-five percent of
    its stock to a third party, Vital Signs. Baxter sued O.R.
    claiming that it “was in breach of the Agreement because
    the sale of stock constituted an assignment of O.R.’s
    interest in the Agreement to Vital Signs. Baxter asserted
    12                                                 No. 08-1359
    that such an assignment was in violation of a provision
    of the Agreement requiring Baxter’s written consent
    prior to O.R. assigning its interest in the Agreement.” 
    Id. at 787.
    We disagreed and explained accordingly:
    Baxter fails to demonstrate how the change of owner-
    ship of O.R. stock constitutes an assignment of O.R.’s
    interests in the Agreement. It is well settled that a
    change in corporate ownership does not constitute a
    variation of that corporation’s contractual obligations.
    U.S. Can Co. v. NLRB, 
    984 F.2d 864
    , 868 (7th Cir. 1993)
    (“A sale of stock, like a merger, does not affect the
    contractual obligations of the corporation.”); United
    States Shoe Corp. v. Hackett, 
    793 F.2d 161
    , 163-164 (7th
    Cir. 1986). Baxter ignores the most fundamental
    characteristic of a corporate entity: its independence.
    Flynn v. Allis Chalmers Corp., 
    634 N.E.2d 8
    , 10 ([Ill. App.
    Ct.] 1994) (“In Illinois, a corporation is deemed a
    distinct legal entity, separate from other corporations
    with which it may be affiliated.”); Peoples Energy Corp.
    v. Illinois Commerce Comm’n, 
    492 N.E.2d 551
    , 558 ([Ill.
    App. Ct.] 1986) (“The general rule . . . is that holding
    companies and their subsidiaries are separate legal
    entities.”). O.R. has at all times remained an independ-
    ent and functioning organization. That fact has not
    been affected by its change in ownership. The most
    persuasive demonstration of this is that Baxter itself
    chose O.R. as the proper party to sue in this action, not
    its owners. Because the change in stock ownership did
    not change O.R.’s obligations under the Agreement,
    O.R.’s interests in the Agreement are still O.R.’s inter-
    ests. They have not been assigned to anyone.
    No. 08-1359                                                13
    
    Id. at 788
    (parallel citations omitted). Absent special
    circumstances, therefore, a change in ownership does
    not affect the contractual obligations of the company,
    that is, it does not effect an assignment of rights.
    Applying this general rule to the present circumstances,
    the transfer of BP Amoco Polymers stock to another
    company did not constitute an assignment of rights for
    purposes of Article 19.A. Article 19.A. addresses only
    assignments of rights under the Supply Agreement. It
    does not define the term “assignment” or “assign”; there-
    fore, according to Illinois law, the term must be accorded
    its common and usual meaning. See Dean Mgmt., Inc. v. TBS
    Const., Inc., 
    790 N.E.2d 934
    , 940 (Ill. App. Ct. 2003) (“Be-
    cause the contract does not define ‘written notice,’ we must
    give the term its common and generally accepted mean-
    ing.” (internal citations omitted)); Michigan Ave. Nat’l Bank
    of Chicago v. Evans, Inc., 
    531 N.E.2d 872
    (Ill. App. Ct. 1988)
    (“Since the lease does not define the term ‘sale’, it will be
    assumed that the word is intended to be used in its usual
    meaning.”). As set forth above, the general rule is
    that a change in corporate ownership does not
    effectuate an assignment of rights. Baxter 
    Healthcare, 69 F.3d at 788
    (“It is well settled that a change in corporate
    ownership does not constitute a variation of that corpora-
    tion’s contractual obligations.”).
    BASF Catalysts acknowledges this general rule, however,
    it claims that, in the present case, the general rule simply
    does not apply: “The distinction that INEOS ignores is
    that those cases simply stand for the proposition that non-
    assignment clauses are not generally triggered by changes
    in control of a contracting party . . . .” Appellee’s Br. at
    14                                                    No. 08-1359
    16. This general principle, BASF Catalysts continues, “is
    contrasted with Article 19.A. of the Agreement, which
    specifies that no change in control of Amoco Chemical
    from Amoco Corporation, or of CRI from Phillips, would
    be permitted without the consent of the other party.” 
    Id. (emphasis added).
       We cannot agree that the language of Article 19.A. takes
    it outside of the general rule articulated in Baxter
    Healthcare. Article 19.A. is completely silent with respect
    to a change in ownership or a change in control. By con-
    trast, it explicitly addresses assignments of the Supply
    Agreement and provides that, with an exception for
    certain intra-corporate transfers, the rights may not be
    assigned absent consent by the parties.
    Essentially, the district court read the exception in the
    first sentence of Article 19.A.,6 not as providing a more
    permissive approach for assignments to affiliated corpora-
    tions, but as prohibiting any change in ownership without
    prior consent. However, we cannot square the district
    court’s reading of Article 19.A. with general rules of
    contract interpretation or with the other provisions of the
    6
    See R.50-2, Ex. A at 95-96 (“Neither party may assign this
    Agreement, or any part thereof, without the prior written
    consent of the other, except that Amoco may assign this Agreement
    in its entirety only without the consent of CRI at any time to an
    entity owned fifty percent (50%) or more, directly or indirectly, by
    Amoco Corporation, and CRI may assign this Agreement in its
    entirety only without the consent of Amoco to any company
    one hundred percent (100%) owned, directly or indirectly, by
    Phillips.”) (emphasis added).

    Supply Agreement. The “except” clause of Article 19.A.
    follows the absolute bar to assignment of contractual rights
    found earlier in the same sentence: “Neither party may
    assign this Agreement, or any part thereof, without the
    prior written consent of the other . . . .” The “except”
    clause, therefore, provides a permissive exception to the
    general prohibition of assignment of contractual rights to
    affiliate entities.
    Furthermore, the district court’s interpretation of
    Article 19.A. makes other portions of that article super-
    fluous. According to the district court, any change in
    corporate ownership is governed by the consent require-
    ment of Article 19.A.; in other words, any successor
    corporation also is an assignee for purposes of Article 19.A.
    However, the provision at the end of Article 19.A.—that
    the Supply Agreement should be binding on the parties’
    “successors and permitted delegatees and assign-
    ees”—does not treat successors and assignees as inter-
    changeable. Therefore, equating successors and assignees,
    for purposes of Article 19.A., would violate the principle
    of contract interpretation that “meaning and effect must
    be given to every part of the contract including all its
    terms and provisions, so no part is rendered meaningless
    or surplusage unless absolutely necessary.” Coles-Mountie
    Elec. Co-op. v. City of Sullivan, 
    709 N.E.2d 249
    , 253 (Ill.
    App. Ct. 1999); see also Miniata v. Ed Miniata, Inc., 
    315 F.3d 712
    , 715 (7th Cir. 2002) (applying the Illinois rule of
    construction).
    Finally, the district court’s interpretation of Article 19.A.
    would render meaningless much of Article 17 and, there-
    fore, violate the same rule of construction. If Article 19.A.’s
    16                                                  No. 08-1359
    language governing assignments also prohibits any
    change of control or ownership without consent, then
    Article 17’s specific proscription of Phillips’ ability to “sell,
    transfer, assign, grant any option with respect to, merge
    or otherwise dispose of any of the ownership or control
    of CRI,” absent certain conditions being met, is mere
    surplusage. Article 17 specifically addresses a change
    in corporate control. It provides that neither CRI nor
    Phillips shall “sell, transfer, assign, grant any option
    with respect to, merge or otherwise dispose of any of the
    ownership or control of CRI” absent certain conditions being
    met, namely Amoco being afforded the right of first
    refusal. R.50-2, Ex. A at 95-96 (emphasis added).7 The
    separate mention of “dispos[ition] of any of the owner-
    ship or control of CRI” demonstrates that, with respect
    to Article 17.A, the parties chose to mention explicitly a
    change in ownership or control, but, with respect to
    Article 19.A., did not.
    In sum, according the terms of the Supply Agreement
    their usual meaning and giving effect to all of the terms
    of the Supply Agreement, we cannot conclude that the
    face of the contract is susceptible only to the district
    court’s interpretation. By contrast, the language and
    structure of the Supply Agreement strongly suggest that
    7
    Given that the CD-Catalyst was “vital” to the polypropylene
    production of Amoco Chemical and its licensees, it is under-
    standable why it would insist on a right to first refusal. It
    needed to ensure that whoever succeeded to CRI’s business
    was capable of producing the CD-Catalyst according to specifi-
    cations, within the parties’ pricing structure, for the long
    term. See R.50-2 ¶ 2.
    No. 08-1359                                                    17
    Article 19.A. is a provision meant to address only assign-
    ment of rights. Because the corporate mutations that
    occurred between 1992 and 2006 on Amoco’s side of the
    Supply Agreement did not involve assignments of rights
    that required consent by CRI (or its successors), INEOS
    Polymers is not an impermissible assignee. Consequently,
    at this stage in the litigation, we cannot conclude that
    INEOS Polymers is unable to prosecute this action
    against BASF Catalysts and BASF AG.
    B. Course of Performance
    The parties’ course of performance over the life of the
    Supply Agreement also calls into question the district
    court’s interpretation. With respect to all of the corporate
    reorganizations and changes in ownership during the
    life of the Supply Agreement, no party raised Article 19.A.
    as a barrier to any transaction until the present dispute
    arose. By contrast, the documents executed at the time
    of each of the transfers of ownership of CRI (or one of
    its successors) showed that the parties understood that
    Article 17.A., giving Amoco a right to first refusal, not
    Article 19.A.’s assignment language, was implicated by
    the sale.8

    The letters with respect to the sale of CRI to Mallinckrodt are
    not attached to the Second Amended Complaint, but their
    contents are alleged in ¶ 35. See R.50-2. These allegations
    must be accepted as true for purposes of a motion to dismiss.

    Furthermore, for its part, BASF Catalysts has not been
    able to articulate with any consistency which corporate
    changes it believed were impermissible and why it did
    not object, contemporaneously, to those assignments.
    For instance, in the district court, BASF Catalysts
    initially claimed that the merger of Amoco with a BP
    subsidiary (with the consequent change in ownership of
    Amoco Polymers) was an impermissible assignment, see
    R.36 at 8-9; however, it never introduced evidence of a
    contemporaneous objection to that change in ownership
    under Article 19.A. It subsequently changed its position
    in the district court and stated that it was not objecting
    to the merger with BP, but offered no rationale why it
    was abandoning this claim. See R.56 at 6 n.2. However,
    BASF Catalysts now offers the following explanation as
    to why the creation of BP Amoco Polymers, after the
    merger of Amoco Corporation with a BP subsidiary, was
    acceptable: “The change of ownership language applied
    only to Amoco Chemical and CRI; their ownership by
    intermediate companies was irrelevant, so long as they
    were ultimately owned by Amoco Corporation and
    Phillips (or their successors).” Appellee’s Br. at 23.
    Given BASF Catalysts’ evolving position with respect
    to the BP merger, it is hard to disagree with INEOS Poly-
    mers’ claim that “BASF had to invent this distinction in
    8
    (...continued)
    to Engelhard, see R.50-2, Ex. B, as well as the leaseback agree-
    ments entered by Engelhard, see R.50-2, Exs. C and D, are all
    attached to the Second Amended Complaint and reference
    Article 17, but make no mention of rights under Article 19.A.
    No. 08-1359                                                   19
    order to explain why INEOS Holding’s acquisition re-
    quired consent but the prior transactions involving BP and
    BASF’s own acquisition of Engelhard did not.” Reply Br.
    at 9. It is difficult to reconcile this new argument of
    BASF Catalysts with its stated understanding of Article
    19.A.—that it is a general prohibition against one party
    “foist[ing] an entity controlled by a stranger onto the
    other without the other’s consent.” See Appellee’s Br. at 7.
    Ineos Polymers alleged in its complaint conduct by the
    parties that strongly suggests that the parties understood
    that the requirements of Article 17, as opposed to those
    of Article 19.A., were implicated by changes in corporate
    ownership. These allegations, when taken as true, serve
    as further evidence that the district court’s interpretation
    of the Supply Agreement cannot be upheld as a matter
    of law. Cf. Harris Trust & Sav. Bank v. Hirsch, 
    445 N.E.2d 1236
    (Ill. App. Ct. 1983) (“[W]hile conduct is not conclu-
    sive, the court will look to the parties’ action under a
    contract as strongest evidence of their meaning since
    the parties to an agreement know best what they meant.”).9
    Conclusion
    For the reasons set forth above, it is not clear from
    the face of the contract that INEOS Polymers is an imper-
    missible assignee—the sole basis for the district
    9
    Because we determine that the contract language is susceptible
    to a reading that allows INEOS Polymers to maintain this
    action, we need not reach, at this stage in the litigation, INEOS
    Polymers’ arguments concerning waiver and estoppel.

    court’s dismissal of INEOS Polymers’ action against
    BASF Catalysts and BASF AG. Consequently, the judgment
    of the district court is reversed, and the case is remanded
    for further proceedings consistent with this opinion.
    Circuit Rule 36 shall apply. INEOS Polymers may recover
    its costs in this court.
