    No. 11-30038
    DENNIS, Circuit Judge:1
    This case involves a contractual interpretation dispute over whether
    overriding royalties are payable out of the initial oil and gas production from a
    tract of land on the outer continental shelf adjacent to Louisiana. In 1998,
    pursuant to the Outer Continental Shelf Lands Act (“OCSLA”),2 the United
    States issued a mineral lease of the tract to oil companies for mineral
    exploration. In 1999 and 2001, overriding royalty interests (“ORRI”) were
    carved out of the lessees’ working interest in all production and assigned to
    seven individuals referred to herein as the “Belcher Group” (ORRIs totalling
    0.2625% assigned in 1999) and to Kerr-McGee Oil and Gas Corporation (“Kerr-
    McGee”) (ORRI of 3.7373% assigned in 2001).
    When production under the lease was obtained in 2009, three oil
    companies owned the lessees’ working interests: Chevron USA, Inc. (“Chevron”)
    (58% share), Total E&P USA, Inc. (“Total”) (17% share), and Statoil Gulf of
    Mexico, L.L.C. (“Statoil”) (25% share). Chevron immediately began paying
    overriding royalties out of its share of the production to the Belcher Group and
    Kerr-McGee. Total and Statoil, however, took the position that they were not
    obliged to immediately begin paying overriding royalties out of their shares of
    production. They claimed that no overriding royalties were due because the
    ORRI assignment contracts contained “calculate and pay” clauses stating that:
    “The overriding royalty interest assigned herein shall be calculated and paid in
    the same manner and subject to the same terms and conditions as the
    landowner’s royalty under the Lease.”3 Total and Statoil asserted that the
    1
    Our prior opinion, 
    711 F.3d 478
     (5th Cir. Mar. 12, 2013), is vacated and withdrawn
    and this opinion is substituted in its place.
    2
    
    43 U.S.C. § 1331
     et seq.
    3
    Although the two “calculate and pay” clauses vary slightly in wording, it is undisputed
    that they are identical in substance.
    2
    Case: 11-30038       Document: 00512282396          Page: 3     Date Filed: 06/20/2013
    No. 11-30038
    “calculate and pay” clauses were intended to suspend their obligation to pay
    overriding royalties out of production whenever payments of the United States’
    12½% landowner royalty under the lease were to be suspended pursuant to the
    Outer Continental Shelf Deep Water Royalty Relief Act (“DWRRA”).4
    It is undisputed that, upon the commencement of production under the
    lease in 2009, the payment of the government’s 12½% landowner royalties was
    determined to be suspended until 87.5 million barrels of oil equivalent had been
    produced, pursuant to the DWRRA. Therefore, Total and Statoil argue, no
    overriding royalties are due so long as the payment of the U.S. landowner
    royalties are suspended.         The Belcher Group and Kerr-McGee disagreed,
    contending that the “calculate and pay” clauses were not intended to suspend
    overriding royalties under any circumstances but were meant to ensure that
    overriding royalties would be calculated using the same methods as required by
    the lease for measuring and computing the government’s 12½% landowner
    royalties. In other words, they argued that the “calculate and pay” clauses were
    intended to specify the manner of calculation and payment of overriding
    royalties, not to make the accrual of overriding royalties dependent upon the
    payment of landowner royalties to the United States. This litigation ensued.
    Because Chevron agreed with the ORRI owners’ interpretation of the “calculate
    and pay” clauses and continued to pay overriding royalties to them, Chevron has
    not been sued or made a party to this case.5
    The district court granted a motion for summary judgment by Total and
    Statoil, declaring that the “calculate and pay” clauses in the 1999 and 2001
    4
    Pub. L. No. 104-58 (1995) (codified at 
    43 U.S.C. § 1337
    (a), and with further uncodified
    sections present in notes to 
    43 U.S.C. § 1337
    ).
    5
    The district court correctly determined that it had jurisdiction over this action
    pursuant to OCSLA’s broad jurisdictional grant, 
    43 U.S.C. § 1349
    (b)(1). See, e.g., Tidelands
    Royalty “B” Corp. v. Gulf Oil Corp., 
    804 F.2d 1344
    , 1347 n.1 (5th Cir. 1986).

    Case: 11-30038     Document: 00512282396      Page: 4    Date Filed: 06/20/2013
    No. 11-30038
    ORRI assignments clearly and explicitly require that the payment of overriding
    royalties shall be suspended during the suspension of the U.S. 12½%
    landowner’s royalty under the DWRRA. The district court expressly refused to
    engage in further interpretation of the assignment contracts in search of the
    parties’ intent or to consider any evidence on that issue.
    The Belcher Group and Kerr-McGee appealed. The issue on appeal comes
    down to whether the language in the “calculate and pay” clauses providing that
    the overriding royalties “shall be calculated and paid in the same manner and
    subject to the same terms and conditions as the landowner’s royalty under the
    lease” clearly, explicitly, and unambiguously was intended to suspend the
    payment of overriding royalties if, upon production, the DWRRA were to result
    in a threshold suspension of the payment of landowner royalties to the United
    States.
    We conclude, under the applicable Louisiana law, that the “calculate and
    pay” clauses in the ORRI assignment contracts do not clearly and explicitly
    express the intent that overriding royalty payments shall be suspended
    whenever the U.S. landowner royalties are suspended under the DWRRA; and
    that the “calculate and pay” clauses must be interpreted further in search of the
    common intent of the parties to the assignment contracts. Assuming without
    deciding that the “calculate and pay” clauses may reasonably be interpreted as
    Total and Statoil contend, the clauses are at least ambiguous because a
    reasonable inference also may be drawn that the “calculate and pay” clauses
    merely refer to the lease terms and conditions for the method of calculating
    overriding royalties and that they do not intend for the lessees’ obligation to pay
    overriding royalties out of production to be suspended altogether under any
    circumstances. Because of this ambiguity and permissible inference, there is a
    genuine dispute as to a material issue of fact, viz., the assignment contract
    parties’ intentions regarding the “calculate and pay” clauses.          Therefore,
    4
    Case: 11-30038         Document: 00512282396           Page: 5     Date Filed: 06/20/2013
    No. 11-30038
    because, in reviewing the summary judgment de novo, we must resolve all
    ambiguities, permissible inferences, and material issues of fact in favor of the
    non-moving parties, the Belcher Group and Kerr-McGee, we conclude that
    Total and Statoil are not entitled to a judgment as a matter of law. For these
    reasons, we reverse the district court’s summary judgment and remand the case
    to it for further proceedings.
    BACKGROUND
    A.     Relevant Federal Statutes, Regulations, and Interpretations
    To understand the legal context within which the ORRI assignment
    contracts must be interpreted, it is helpful to have a general understanding of
    the governing federal statutes and regulations, as they have been interpreted by
    this court.6
    “[OCSLA] authorizes the Secretary of the [Interior] to grant and manage
    leases for recovery of oil, gas, and other minerals from submerged lands located
    on the Outer Continental Shelf.” Mesa Operating Ltd. P’ship v. U.S. Dep’t of
    Interior, 
    931 F.2d 318
    , 319 (5th Cir. 1991). “OCSLA thus vests the federal
    government with a proprietary interest in the [outer continental shelf] and
    establishes a regulatory scheme governing leasing and operations there.” EP
    Operating Ltd. P’ship v. Placid Oil Co., 
    26 F.3d 563
    , 566 (5th Cir. 1994).
    “OCSLA provides that the [Department of the Interior (‘DOI’)] obtains royalties
    from lessees based on the ‘amount or value of the production saved, removed, or
    sold.’” Mesa Operating Ltd., 
    931 F.2d at 319-20
     (quoting 
    43 U.S.C. § 1337
    (a)(1)).
    6
    Section 1 of the lease provides: “This lease is issued pursuant to the Outer Continental
    Shelf Lands Act of August 7, 1953, 
    67 Stat. 462
    ; 
    43 U.S.C. § 1331
     et seq., as amended (
    92 Stat. 629
    ), (hereinafter called the ‘Act’). The lease is issued subject to the Act; all regulations issued
    pursuant to the Act and in existence upon the Effective Date of the this lease; all regulations
    issued pursuant to the statute in the future which provide for the prevention of waste and
    conservation of all natural resources of the Outer Continental Shelf and the protection of
    correlative rights therein; and all other applicable statutes and regulations.”

    No. 11-30038
    “OCSLA also vests in the Secretary the sole authority and responsibility
    to ‘prescribe such rules and regulations as may be necessary to carry out such
    [leasing] provisions [of OCSLA].’” Id. at 319 (alterations in original) (quoting 
    43 U.S.C. § 1334
    (a)). Pursuant to this authority, the DOI has several times issued
    regulations governing how royalties on production from OCSLA leases are to be
    computed and how lessees are to record and report production information
    relevant to those calculations. The regulations in effect when the lease here was
    issued in June 1998 were promulgated by the DOI agency then known as the
    Mineral and Mining Service (“MMS”). Those regulations provided, inter alia,
    that “[a]ll oil (except oil unavoidably lost or used on, or for the benefit of, the
    lease, including that oil used off-lease for the benefit of the lease when such off-
    lease use is permitted by the [agency], as appropriate) produced from a Federal
    . . . lease . . . is subject to royalty,” 
    30 C.F.R. § 202.100
    (b)(1) (1997); and that
    “[w]hen paid in value, the royalty due shall be the value, for royalty purposes,
    [under the regulations] multiplied by the royalty rate in the lease,” 
    id.
    § 202.100(a)(1).7 These provisions apply to the United States’ landowner’s
    royalty owed by OCSLA mineral lessees and not to overriding royalties owed by
    lessees to third party ORRI owners.
    7
    The regulations also set “[t]he value of oil production from [OCSLA] leases” by
    reference to “[t]he lessee’s contemporaneous posted prices or oil sales contract prices used in
    arms-length transactions for purchases or sales of significant quantities of like-quality oil in
    the same field,” or pursuant to one of several alternative formulas. 
    30 C.F.R. § 206.102
    (c)
    (1997). “Value [was] based on the highest price a prudent lessee can receive through legally
    enforceable claims under its contract.” 
    Id.
     § 206.102(j). “[U]nder no circumstances [was] the
    value of production, for royalty purposes, [to] be less than the gross proceeds accruing to the
    lessee for lease production, less applicable allowances.” Id. § 206.102(h). Lessees were
    required to “make available, upon request to the authorized [government officials], arm’s-
    length sales and volume data for like-quality production sold, purchased, or otherwise
    obtained by the lessee from the field or area or from nearby fields or areas.” Id. § 206.102(d).

    No. 11-30038
    The DWRRA, enacted in 1995 to stimulate deepwater mineral
    exploration,8 authorized the DOI to suspend the collection of oil and gas royalties
    by the United States as landowner from certain new and preexisting federal,
    deepwater leases until specified threshold volumes of production had been
    attained, at which time landowner royalty payments would recommence. See
    Santa Fe Snyder Corp. v. Norton, 
    385 F.3d 884
    , 888-89 (5th Cir. 2004).
    Additionally, for new deepwater leases issued between 1996 and 2000 for specific
    areas and depths in the Gulf of Mexico, DWRRA § 304 provided qualified lessees
    with relief from royalty payments to the United States until a specific volume
    of oil or gas had been produced. Id. at 889. However, in issuing federal leases
    during this period, MMS by regulation prescribed that “one royalty suspension
    volume [would be] shared by all leases producing from a single field” and
    “imposed a requirement for policy reasons that no royalty suspension would be
    available to leases in fields when any well in that field produced oil or gas prior
    to the enactment of the [DWRRA].” Id. at 891. The agency also “impose[d] price
    thresholds requiring the payment of royalties on volumes less than the volume
    thresholds set by [the DWRRA].” Kerr-McGee Oil & Gas Corp. v. U.S. Dep’t of
    Interior, 
    554 F.3d 1082
    , 1083 (5th Cir. 2009). When oil and gas prices moved
    above those price thresholds, the DOI sought to collect royalties on these leases,
    despite the fact that the congressionally set volume thresholds had not yet been
    met. 
    Id.
    In Kerr-McGee, an oil company challenged the DOI’s order to pay such
    royalties, and this court concluded that the agency did not have the authority to
    8
    See, e.g., 
    43 U.S.C. § 1337
    (a)(3)(B) (providing that the DOI may suspend government
    royalties “in order to . . . promote development or increased production on producing or non-
    producing leases[] or . . . encourage production of marginal resources” on such leases); 
    63 Fed. Reg. 2605
    -1 (Jan. 16, 1998) (“[The DWRRA’s] purpose is to promote development or increased
    production, or to encourage production of marginal resources, for [Gulf of Mexico] leases lying
    west of 87 degrees, 30 minutes West longitude.”).
    7
    Case: 11-30038        Document: 00512282396           Page: 8      Date Filed: 06/20/2013
    No. 11-30038
    impose price thresholds requiring the payment of royalties to the government on
    volumes less than the volume thresholds set by Congress in the DWRRA. Id.
    at 1086-87. The court looked to its 2004 decision in Santa Fe Snyder Corp.,
    which had held that DWRRA § 304 extends royalty relief to each new lease at
    statutorily-specified locations and water-depths and that the DOI did not have
    the authority to limit this royalty relief to new leases that first resulted in
    production from a field. See Kerr-McGee, 
    554 F.3d at 1085-86
    . Consequently,
    until this court’s 2004 and 2009 decisions interpreting and clarifying the
    meaning and application of § 304, it could not be predicted with certainty
    whether production from a particular new oil and gas well would definitely
    qualify for a suspension of the U.S. landowner’s royalty under the DWRRA.
    B.     The OCSLA Lease and the ORRI Assignment Agreements
    MMS issued Lease OCS-G 20082, to Mariner Energy, Inc., and Westport
    Oil and Gas Company, Inc. (“Westport”) pursuant to 
    43 U.S.C. § 1337
     and
    effective June 1, 1998. The form lease describes the leased property as “[a]ll of
    Block 640, Green Canyon, OCS Official Protraction Diagram, NG 15-3.” The
    property is located approximately 190 miles south of New Orleans. The lease
    was issued with a lessor’s royalty rate of 12½ per cent. A footnote to this royalty
    rate provision states: “This lease may be eligible for royalty suspension pursuant
    to PL 104-58. If eligible, Sections 5 and 6 [providing for payment of royalty to
    Lessor] of this lease instrument will be suspended by 30 C.F.R. Part 26,
    published in the Federal Register on January 16, 1998 (63 FR 2626).”9
    9
    Sections 5 and 6 of the form lease are boilerplate provisions specifying, inter alia, that
    “[t]he Lessee shall pay the Lessor, at the expiration of each lease year which commences after
    a discovery of oil and gas in paying quantities, a minimum royalty” of 12½%; that “[t]he Lessee
    shall pay [this] fixed royalty . . . in amount or value of production saved, removed, or sold from
    the leased area”; that “[t]he Lessor shall determine whether production royalty shall be paid
    in amount or value”; and that “[t]he value of production for purposes of computing royalty on
    production from this lease shall never be less than the fair market value of the production.”

    No. 11-30038
    On November 3, 1999, Westport executed an assignment conveying to six
    of the seven of the Belcher Group appellees ORRIs “payable out of all oil, gas,
    and casing head gas and associated substances produced, saved, and marketed
    from the lease” (emphasis added) in the following percentages: Wayne G.
    Zeornes 0.125%; Gary Al Hummel 0.125%; Kevin A. Small 0.125%; C. Dan Bump
    0.025%; Allan D. Keel 0.025%; Lynn S. Belcher 0.0625%. These individuals were
    Westport geoscientists and landmen whom the company chose to reward with
    extra compensation by carving overrides for them out of its working interest.
    The six Wesport geoscientists and landmen held on to their overrides, except for
    Zeornes, who split his override with his ex-wife, Cathy Zeornes Guy. Kerr-
    McGee received a 3.7373% ORRI in 2001 pursuant to an assignment containing
    a “calculate and pay” provision substantively identical to that in the Belcher
    Group assignment, which stated that “[t]he overriding royalties described herein
    shall be calculated and paid in the same manner and subject to the same terms
    and conditions as the landowner’s royalty under the Lease.”
    C.    Production Under the Lease and District Court Litigation
    Production under the lease began in May 2009. Chevron then began
    paying the ORRI owners their designated overriding royalty shares from its
    working interest production and has continued to do so ever since. Total began
    approving and issuing payments to the override owners but stopped after paying
    the Belcher Group about $54,000 in royalties. Statoil made no payments to the
    overriding royalty owners. These refusals to pay overriding royalties were
    premised on Statoil and Total adopting the position that they were not obligated
    to make any payments to appellants until the lease produced 87.5 million barrels
    of oil equivalent, on the theory that the “calculate and pay” provisions subjected
    appellants’ ORRIs to suspension along with the U.S. landowner’s royalty under
    the DWRRA.
    9
    Case: 11-30038     Document: 00512282396     Page: 10   Date Filed: 06/20/2013
    No. 11-30038
    On October 2, 2009, Total filed suit against the ORRI owners, the Belcher
    Group and Kerr-McGee, in the U.S. District for the Eastern District of Louisiana
    seeking a declaratory judgment embracing Total’s interpretation of the ORRI
    assignments. In January 2010, the Belcher Group filed suit against Statoil
    seeking declaratory judgment that the lessees were obliged to pay overriding
    royalties to the ORRI owners from first and all production. The district court
    consolidated the cases. Through interventions, third-party claims, and
    counterclaims, Total and Statoil became aligned against the Belcher Group and
    Kerr-McGee.
    Total and Statoil moved for summary judgment, contending that the ORRI
    assignment contracts’ “calculate and pay” clauses clearly and explicitly
    demonstrate the contracting parties’ intent that overriding royalty payments to
    ORRI owners shall be suspended whenever the government’s 12½% landowner
    royalty becomes suspended under the DWRRA. Total and Statoil did not submit
    any affidavits or other evidence in support of their motion for summary
    judgment. Instead, they relied upon what they contend to be the clear and
    explicit words of the “calculate and pay” clauses of the assignment contracts.
    In opposition to appellees’ motion for summary judgment, appellants
    submitted affidavits by the individual members of the Belcher Group and by the
    Westport official who approved both of the original ORRI assignments, attesting
    that the parties to those assignments intended by the “calculate and pay” clauses
    to refer to the lease for the purpose of measuring and computing overriding
    royalties and not for the purpose of suspending overriding royalties during the
    suspension of the U.S. landowner’s royalty under the DWRRA.            Also, the
    appellants submitted an expert witness’ survey of representatives of other oil
    companies operating in the Gulf of Mexico. This survey purportedly identified
    at least eighty other overriding royalty instruments containing “calculate and
    pay” provisions like that at issue here and determined that no other company
    10
    Case: 11-30038       Document: 00512282396          Page: 11     Date Filed: 06/20/2013
    No. 11-30038
    party to such an instrument interpreted these provisions to subject overriding
    royalty interests to “royalty suspension” under the DWRRA. Appellants also
    submitted other affidavits and sworn statements from individuals familiar with
    the Gulf of Mexico oil industry supporting their reading of the “calculate and
    pay” provision. Appellants did not cross-move for summary judgment.
    On December 14, 2010, the district court granted summary judgment for
    the appellees, concluding that the “calculate and pay” provisions clearly and
    explicitly express the common intent of the assignment contract parties that the
    payment of overriding royalties shall be suspended whenever the payment of the
    government’s 12½% landowner’s royalty is suspended under the DWRRA.10 In
    sum, the district court reasoned as follows:
    [I]t is undisputed that the DWRRA applies to the subject Lease,
    and thus, the federal government’s royalty is suspended during
    production of the first 87.5 million barrels of oil equivalent. . . . [T]he
    subject “calculate and pay” clauses are not ambiguous because they
    clearly provide that the overriding royalties “shall be calculated and
    paid in the same manner and subject to the same terms and
    conditions as the landowner’s [federal government’s] royalty under
    the Lease.” Thus, Total’s and Statoil’s payments of the overriding
    royalty interest payments are suspended until production reaches
    the 87.5 million barrels of oil equivalent.
    Total E&P USA, Inc. v. Kerr-McGee Oil & Gas Corp., Nos. 09-CV-6644 &
    10-CV-106, 
    2010 WL 5207591
    , at *4 (E.D. La. Dec. 14, 2010) (fourth alteration
    in original).
    10
    Appellants argue in the alternative that the contract should be reformed on the basis
    of mutual mistake because none of the original contracting parties to the assignment of
    overriding royalty interests intended that the clause would have the meaning ascribed to it
    by the district court. Because we conclude that the ORRI assignment contracts containing the
    “calculate and pay” provisions do not clearly and explicitly require that payment of overriding
    royalties from production shall ever be suspended because the government’s landowner royalty
    is suspended, and that further interpretation is required in search of the assignment parties’
    intent, we reverse and remand the case for further proceedings in that regard, without

    No. 11-30038
    The district court refused to consider the opposing affidavits served and
    filed by appellants as extrinsic evidence tending to show the original assignment
    parties’ intent that the “calculate and pay” clauses refer to the terms and
    conditions of the lease for the purpose of measuring and computing the
    overriding royalties and not for the purpose of defeating or deferring overriding
    royalties while the government’s 12½% landowner’s royalty is suspended under
    the DWRRA. The district court concluded that the provision regarding words of
    art and technical terms set forth in Louisiana Civil Code article 204711 did not
    apply because “there is no one word or group of words in the subject ‘Calculate
    and Pay’ provisions that is subject to a technical meaning.” Total, 
    2010 WL 520791
    , at *4. The district court thus stated that it “need not consider extrinsic
    evidence to give the words of these provisions their generally prevailing
    meaning.” 
    Id.
     After quoting Civil Code article 2046,12 the district court further
    reasoned:
    Here, there are no absurd consequences of tying the overriding
    royalty owners’ payments to those of the federal government as
    landowner, and treating the overriding royalty owner no better or
    worse than the federal government. The DWRRA was enacted
    several years before either assignment here was executed, and the
    original parties to the assignments were charged with the
    knowledge of that law before the assignments were executed. If the
    original parties to the assignments had intended to provide for
    payment of the overriding royalties on the first 87.5 million barrels
    when federal royalties on the same production was suspended by
    the DWRRA, they were obligated to “expressly state their intent in
    [their] agreement.”

    that Louisiana contract law governs the interpretation of the ORRI assignment
    contracts at issue, “[t]o the extent that [law is] applicable and not inconsistent

    Under Louisiana law, the essential quality of an overriding oil and gas
    royalty is that of a real right to receive and collect a fraction or a percentage of
    the production of minerals, carved out of the mineral lessee’s or the servitude
    owner’s working interest in production, free of drilling and production costs.
    The Louisiana Supreme Court has explained that “[t]he lessor’s royalty is
    distinguished from the mineral royalty and the overriding royalty. The former
    is the right to participate in the production of mineral from land or a servitude
    belonging to another, La. Rev. Stat. § 31:80, while the latter is carved out of the
    lessee’s working interest in the lease.” Frey v. Amoco Prod. Co.,

    gas produced at the surface, free of the expense of production, and in addition to
    the usual landowner’s royalty reserved to the lessor in an oil and gas lease”).
    The Louisiana Supreme Court has consistently applied the Louisiana Civil
    Code articles on the interpretation of contracts, along with other applicable
    provisions of state law, in deciding cases involving oil and gas lease and royalty
    questions. See, e.g., Frey, 
    603 So. 2d at 172
    . The court has summarized the
    relevant principles as follows:
    The purpose of interpretation is to determine the common intent of
    the parties. See La. Civ. Code art. 2045. Words of art and technical
    terms must be given their technical meaning when the contract
    involves a technical matter, see La. Civ. Code art. 2047, and words

    susceptible of different meanings are to be interpreted as having the
    meaning that best conforms to the object of the contract. See La.
    Civ. Code art. 2048. A doubtful provision must be interpreted in
    light of the nature of the contract, equity, usages, the conduct of the
    parties before and after the formation of the contract, and other
    contracts of a like nature between the same parties. La. Civ. Code
    art. 2053. When the parties made no provision for a particular
    situation, it must be assumed that they intended to bind themselves
    not only to the express provisions of the contract, but also to
    whatever the law, equity, or usage regards as implied in a contract
    of that kind or necessary for the contract to achieve its purpose. La.
    Civ. Code art. 2054.
    Frey, 
    603 So. 2d at 172
    .
    In Louisiana, “[p]arol or extrinsic evidence is generally inadmissible to
    vary the terms of a written contract unless there is ambiguity in the written
    expression of the parties’ common intent.” Blanchard v. Pan-OK Prod. Co., Inc.,
    
    755 So. 2d 376
    , 381 (La. Ct. App. 2000). “A contract is considered ambiguous on
    the issue of intent when it lacks a provision bearing on that issue or when the
    language used in the contract is uncertain or is fairly susceptible to more than
    one interpretation.” Id.; accord CLK Co., LLC v. CXY Energy, Inc., 
    972 So. 2d 1280
    , 1287 (La. Ct. App. 2007); see Dixie Campers, Inc. v. Vesely Co., 
    398 So. 2d 1087
    , 1089 (La. 1981) (“[W]e conclude that the contract in this case is susceptible
    to more than one reasonable interpretation rendering it ambiguous and
    uncertain as to the intention of the parties.”). “These rules are applicable even
    to contracts involving rights in immovable property, such as mineral rights.”
    Blanchard, 
    755 So. 2d at 381
    .
    Accordingly, when a contract provision relating to mineral rights is
    ambiguous on a pivotal issue, the Louisiana Supreme Court and Courts of
    Appeal have interpreted the provision as having the meaning that best conforms
    to the object of the contract, in light of the nature of the contract, equity, and
    usages, including extrinsic evidence as to custom and practices in the oil and gas

    418 So. 2d 1334
    , 1339-40
    (La. 1982).13
    Applying the foregoing principles, we conclude that the “calculate and pay”
    clauses do not clearly and explicitly show that the parties to the assignment
    contracts intended that the lessees’ obligation to pay overriding royalties out of
    production would ever be suspended under any circumstances. There is no
    reference whatsoever to “royalty suspension” or “overriding royalty suspension”
    in the assignment contracts.           The “calculate and pay” clauses clearly and
    explicitly provide only that overriding royalties “shall be calculated and paid in
    the same manner and subject to the same terms and conditions as the
    landowner’s royalty under the Lease.” Those clauses do not clearly and explicitly
    state that payment of overriding royalties shall be suspended during the
    temporary or threshold suspension of the payment of the government’s
    landowner royalty under the DWRRA. Consequently, under Civil Code article
    13
    In Henry, the Louisiana Supreme Court explained: “In ascertaining [the contracting
    parties’] intention (where it cannot be adequately discerned from the contract or agreement
    as a whole) the circumstances surrounding the parties at the time of contracting are a relevant
    subject of inquiry.” Henry,

    2046 and the Louisiana cases, a court may not find that the parties intended to
    suspend the overriding royalty obligation based exclusively on the words of the
    calculate and pay clauses but must interpret the overriding royalty contracts
    further in search of the parties’ common intent. See CLK, 
    972 So. 2d at 1286
     (“A
    contract is considered ambiguous . . . when it lacks a provision bearing on [a
    particular] issue or when the language used in the contract is uncertain or is
    fairly susceptible to more than one interpretation.” (quoting Blanchard, 
    755 So. 2d at 381
    )).
    Our conclusion is further supported by the well-recognized distinction
    between overriding royalty interests and a lessor’s royalty.           Unlike the
    government’s royalty reserved under OCSLA, “[a]n overriding royalty [interest]
    is a fractional interest in the gross production of oil and gas under a lease, in
    addition to the usual royalties paid to the lessor.” Meeker v. Ambassador Oil Co.,
    
    308 F.2d 875
    , 882 (10th Cir. 1962) (emphasis added), rev’d on other grounds, 
    375 U.S. 160
     (1963). Thus, an overriding royalty interest “is an interest carved out
    of the lessee’s share of the oil and gas, ordinarily called the working interest, as
    distinguished from the owner’s reserved royalty interest.” 
    Id.
     (emphasis added);
    see also Frey, 
    603 So. 2d at
    171 n.8 (explaining that “[t]he lessor’s royalty is
    distinguished from the . . . overriding royalty” interest, which “is carved out of
    the lessee’s working interest in the lease”).       Particularly in light of this
    longstanding distinction drawn between overriding royalty interests and the
    royalties reserved by the landowner, we disagree with the district court’s
    reasoning that the contracting parties were obligated to expressly state that
    royalty suspension would not apply to appellants’ overriding royalty interests.
    See Total, 
    2010 WL 5207591
    , at *5. Rather, the absence of any clear indication
    anywhere in the assignment contracts, lease, or relevant statutory scheme that
    statutory suspension of government royalties was also, counterintuitively,
    17
    Case: 11-30038    Document: 00512282396       Page: 18   Date Filed: 06/20/2013
    No. 11-30038
    intended to apply to the overriding royalty interests renders the contracts at
    least ambiguous on this issue.
    Moreover, the syntax of the ORRI assignments and lease provisions,
    without further interpretation or evidence, do not clearly or explicitly require the
    reading of them argued for by Total and Statoil. The ORRI assignment contracts
    state that the overriding royalty percentages shall be “payable out of all oil, gas,
    and casing head gas and associated substances produced, saved, and marketed
    from the lease” (emphasis added); and it is undisputed that the lessees’ share of
    production begins with and is payable throughout production from the lease.
    This reasonably can be read to signify that the overriding royalty shall be
    payable from the lessees’ share of production over its entirety, and not only
    during periods in which the landowner is entitled to a royalty share of
    production. Likewise, the simple affirmative declaration that the overriding
    royalty shall be calculated and paid in the same manner and subject to the same
    terms and conditions as the landowner’s royalty is calculated and paid under the
    lease does not indicate that the overriding royalties paid out of the lessees’ share
    of production shall ever be suspended during that production. To require a
    suspension of overriding royalties payable from the lessees’ production before the
    lessees actually cease to receive production from the lease would add an
    exception or condition to the grants of overriding royalties upon which the
    lessees and override owners in those contracts did not clearly or explicitly agree.
    Furthermore, Total and Statoil tacitly concede that they cannot completely
    and finally rely on what they contend to be the clear and explicit words of the
    “calculate and pay” clauses. They ultimately contend that reading these clauses
    of the assignment contracts together with a footnote in the underlying lease
    shows that the assignment parties intended to suspend the override obligation
    during any suspension of the United States’ right to collect landowner’s royalty.
    This alternative argument’s reading together of three different contracts, one to
    18
    Case: 11-30038     Document: 00512282396     Page: 19   Date Filed: 06/20/2013
    No. 11-30038
    which none of the ORRI owners was a party, however, does not produce clear
    and explicit words showing an intent by the original lessees and the ORRI
    owners to suspend the lessees’ obligation to pay them overriding royalties out of
    the lessees’ share of production. It simply adds an indefinite, unclear, and
    ambiguous footnote from the lease to the interpretative problem facing the
    courts in this case.
    The footnote that Total and Statoil seek to rely upon in the underlying
    lease between the United States, as lessor, and Mariner Energy and Westport,
    as lessees, states: “This lease may be eligible for royalty suspension pursuant to
    PL 104-58.    If eligible, Sections 5 and 6 of the lease instrument will be
    superseded by 30 CFR, Part 26, published to the Federal Register on January
    16, 1998 (63 FR 2626).” The footnote does not clearly and explicitly express an
    intention by the lessor and lessees that the lease “shall be eligible” for royalty
    relief under the DWRRA. Therefore, royalty suspension was not clearly and
    explicitly made a term or condition of the lease that was binding on the lease
    parties or third parties. For these reasons, and also because the Belcher Group
    and Kerr-McGee were not parties to the lease, the footnote expresses no clear
    and explicit agreement or intent by the overriding royalty owners to forfeit or
    defer any of their rights to overriding royalties payable by the lessees out of any
    future production under the lease. Furthermore, as we have discussed earlier
    in this opinion, in 1999 and 2001 when the ORRI assignments were made,
    whether production from a particular eligible lease would receive landowner’s
    royalty suspension under the DWRRA, regardless of the fluctuating prices of oil
    and gas or of whether the well was the first in its field, was not reasonably
    foreseeable until the decisions of this court in Santa Fe Snyder Corp. v. Norton,
    
    385 F.3d 884
     (5th Cir. 2004), and Kerr-McGee Oil & Gas Corp. v. U.S. Dep’t of
    Interior, 
    554 F.3d 1082
     (5th Cir. 2009). “In interpreting a contract ‘it should be
    construed in the light of the circumstances surrounding [the parties] at the time
    19
    Case: 11-30038        Document: 00512282396          Page: 20     Date Filed: 06/20/2013
    No. 11-30038
    it is made, it being the duty of the court to place itself as nearly as may be in the
    same situation of the parties at the time, so as to view the circumstances as they
    viewed them, and so to judge the meaning of the words and the correct
    application of the language of the contract.” Henry, 
    418 So. 2d at
    1339 n.12
    (alteration in original). Even if we were to presume that the parties to the
    assignment contracts could foresee that the lessees would be entitled to
    landowner royalty relief under the DWRRA, they still did not subscribe to any
    words that clearly and explicitly state any intent to suspend, forfeit, or defer
    overriding royalty rights. Consequently, reading the “calculate and pay” clauses
    of the ORRI assignment contracts together with the underlying lease’s footnote
    does not clearly and explicitly show that the assignment contract parties
    intended to suspend the lessees’ obligation to pay overriding royalties to the
    ORRI owners whenever the government’s 12½% landowner’s royalty is
    suspended under the DWRRA or that the lessees’ obligations to pay overriding
    royalties out of production to the override owners would be suspended under any
    circumstances.14
    Accordingly, we disagree with the district court, which reached the
    opposite result based on the following reasoning:
    [I]t is undisputed that the DWRRA applies to the subject Lease, and
    thus, the federal government’s royalty is suspended during
    14
    Moreover, as discussed above, under the implementing regulations in force on the
    dates the lease was issued and the assignment contracts were entered, “when production
    occur[red] from an eligible lease, the Interior [Department would] determine[] from what field
    the lease [was] producing and what royalty suspension volume (if any) applie[d] to the lease,”
    and “[n]ew [l]eases only received the benefit of royalty suspension if the lease was determined
    to be in a field that had not produced prior to the enactment of the [DWRRA].” Santa Fe
    Snyder Corp., 
    385 F.3d at 889-90
    . Thus, at the time the form lease was issued, royalty
    suspension was one possible outcome of an administrative process, provided for not by the
    lease but by statute and regulation, and which in turn depended on whether the lease was
    deemed “eligible” and whether the relevant field had produced prior to the effective date of the
    DWRRA. See 
    id.
     The lease nowhere indicates whether the field in which it is located is one
    that had produced prior to that date. Thus, it cannot be said that the footnote constitutes a
    clear and explicit term or condition of the lease requiring a suspension of landowner’s royalty.

    production of the first 87.5 million barrels of oil equivalent. Now,
    having examined the four corners of the subject Assignments and
    interpreting each provision “in light of the other provisions so that
    each is given the meaning suggested by the contract as a whole” (La.
    Civil Code Art. 2050), the court finds that the subject “Calculate and
    Pay” clauses are not ambiguous because they clearly provide that
    the overriding royalties “shall be calculated and paid in the same
    manner and subject to the same terms and conditions as the
    landowner’s [federal government’s] royalty under the Lease.” Thus,
    Total’s and Statoil’s payments of the overriding royalty interest
    payments are suspended until production reaches the 87.5 million
    barrels of oil equivalent.
    Total, 
    2010 WL 5207591
    , at *4 (second alteration in original).
    Of course, the district court is correct that it is now undisputed that the
    DRWWA landowner’s royalty relief applies to the subject lease. But as we have
    pointed out, that was not so when the subject lease was issued in 1998 or when
    the ORRI assignment contracts were entered in 1999 and 2001. Prior to the
    litigation that culminated in our decisions in Santa Fe Snyder Corp. in 2004 and
    Kerr-McGee in 2009, it was at most speculative whether the lessees under the
    subject lease would receive the benefit of DRWWA landowner’s royalty relief if
    and when production were obtained. That is likely why the footnote in the lease
    is indefinite and says only that the lessees “may” be eligible for landowner
    royalty relief.15
    15
    The dissent contends that there is no “lack of clarity regarding whether the royalty
    suspension period was a term of the lease that the overriding royalties became subject to
    through the ‘calculate and pay’ clauses.” As already explained, however, the only reference
    to the DWRRA in the lease is the indefinite and ambiguous statement that the lease “may” be
    eligible for suspension of government royalties under the DWRRA. Moreover, neither the
    DWRRA nor its implementing regulations have ever purported to suspend or affect lessees’
    obligations to pay overriding royalties to ORRI owners out of production. In arguing that this
    “footnote negates the lessee’s duty to make royalty payments,” such that “royalty suspension
    is a term or condition of the landowner’s royalty under the lease,” the dissent conflates
    overriding royalty with landowner royalty and refuses to acknowledge the crucial legal
    distinctions in source and nature of the two kinds of royalty. See, e.g., Frey, 
    603 So. 2d at
    171
    n.8.

    Furthermore, simply because a lessee is entitled to DRWWA relief from
    paying the government landowner royalties until a specified quantity of
    production has occurred does not relieve the lessee from the obligation of
    measuring, calculating, and accounting for its production of oil and gas from the
    leased property. OCSLA and applicable DOI regulations continue to specify how
    that production is measured, calculated, and accounted for. See, e.g., 
    43 U.S.C. § 1337
    (a)(C) (limiting government royalty relief to specific production volumes);
    
    30 C.F.R. §§ 250.1201-03
     (setting forth and incorporating by reference
    requirements for measuring oil and gas production from OCSLA leases); 
    30 C.F.R. §§ 1206.100-60
     (“explain[ing] how [OCS] lessee[s] must calculate the
    value of production for royalty purposes consistent with the mineral leasing
    laws, other applicable laws, and lease terms”); cf. Abraham v. BP Am. Prod. Co.,
    
    685 F.3d 1196
    , 11991203 (10th Cir. 2012) (noting that there are “specific and
    comprehensive federal regulations” setting forth “federal royalty calculation
    requirements”).16 The lease here was, of course, expressly “issued subject to
    [OCSLA] . . . and all . . . applicable statutes and regulations,” including
    specifically “all regulations issued pursuant to [OCLSA] . . . which provide for . . .
    the protection of correlative rights.”             Without clearly stated methods of
    measurement, calculation, and accounting, the federal government as landowner
    would not have certain knowledge of how much production had occurred or when
    its rights to collect landowner’s royalty would recommence. Consequently, the
    “calculate and pay” clauses may reasonably be interpreted as intended to entitle
    the ORRI owners to their share of the lessees’ production under these same
    methods of measurement, calculation, and accounting without relieving the
    16
    All of this tends to bolster the ORRI owners’ argument that the “calculate and pay”
    clauses reasonably can be construed to refer to the federal methods of measuring, calculating
    and paying overriding royalties, rather than to any suspension of overriding royalties, and that
    the “calculate and pay” clauses are therefore ambiguous and require further interpretation.

    No. 11-30038
    lessees of their obligation to pay overriding royalties to the ORRI owners out of
    the entirety of the lessees’ working interest production.
    In other words, the “calculate and pay” clauses reasonably may be
    interpreted to mean that the overriding royalty payments shall be calculated and
    paid by using the same methods prescribed for the measurement and
    computation of the landowner’s royalty under the terms and conditions of the
    lease, which is specifically subject to the federal regulations’ provisions for
    measuring, calculating, and accounting for production, instead of meaning that
    the payment of overriding royalties shall be suspended if the landowner’s royalty
    were to be suspended under the DWRRA. Although we have assumed that Total
    and Statoil’s contrary interpretation is equally as reasonable for purposes of
    their summary judgment motion, we conclude that the clauses are ambiguous
    and require further interpretation in search of the parties’ intent.
    The district court, on the other hand, did not specifically address the
    ORRI owners’ reasonable interpretation of the clauses, despite the ORRI owners’
    extensive arguments for it in their opposition to summary judgment.
    Consequently, the district court erroneously concluded that the clauses are not
    ambiguous but that they clearly and explicitly are meant to suspend overriding
    royalties during any suspension of the landowner’s royalty, as well as, or,
    instead of, to prescribe the methods for their calculation. The district court
    stated that it had examined the assignment contracts, and each of their
    provisions together with the others, and had found “that the subject ‘Calculate
    and Pay’ clauses are not ambiguous because they clearly provide that the
    overriding royalties ‘shall be calculated and paid in the same manner and
    subject to the same terms and conditions as the landowner’s [federal
    government’s] royalty under the Lease.’”       Total, 
    2010 WL 5207591
    , at *4
    (alteration in original). We do not find the district court’s reasoning persuasive
    because the words of the “calculate and pay” clauses are not clear, explicit, and
    23

    unambiguous, and the district court did not offer any other reason for finding
    these provisions unambiguous.
    Because the ORRI owners, the Belcher Group and Kerr-McGee, did not
    file a cross motion for summary judgment or ask for any relief here other than
    a reversal of the district court’s judgment, we do not reach the parties’ other
    arguments or consider the affidavits submitted in opposition to summary
    judgment below. Under Louisiana law, interpretation of a contract is the
    determination of the common intent of the parties, La. Civ. Code art. 2045, and
    when the words of a contract are clear and explicit and lead to no absurd
    consequences, no further interpretation may be made in search of the parties’
    intent, 
    id.
     art. 2046. However, the inverse of Article 2046 is also true: when the
    words of the contract are not clear and explicit, but are ambiguous, a court
    should engage in further interpretation in search of the parties’ intent by
    applying the Louisiana Civil Code articles on contractual interpretation and
    pertinent Louisiana cases.     See, e.g., Henry, 
    418 So. 2d at 1339-40
     (“In
    ascertaining th[e] [contracting parties’] intention (where it cannot be adequately
    discerned from the contract or agreement as a whole) the circumstances
    surrounding the parties at the time of contracting are a relevant subject of
    inquiry. . . . The custom of the industry may also be considered in determining
    the true intent of the parties as to ambiguous contract provisions.”); Russell v.
    City of New Orleans, Dep’t of Prop. Mgmt., 
    732 So. 2d 66
    , 70 (La. Ct. App. 1999)
    (“The words of the contract are not clear and explicit . . . , so further
    interpretation may be made in search of the common intent.”). That is the
    situation here. Therefore, we reverse the district court’s grant of summary
    judgment and remand the case to it for further proceedings in which it should
    consider relevant evidence in interpreting the disputed provisions in accordance
    with applicable principles of Louisiana law on the interpretation of contracts.

    HIGGINSON, Circuit Judge, concurring:
    I agree with Judge Dennis’ reasoning and outcome, but write to explain in
    further detail why I believe the contracts’ language is ambiguous.
    The overriding royalty interest (“ORRI”) assignment contracts contain
    “calculate and pay” clauses stating: “The overriding royalty interest assigned
    herein shall be calculated and paid in the same manner and subject to the same
    terms and conditions as the landowner’s royalty under the Lease.” Like many
    complex sentences, ambiguity exists in this one’s structure. ORRI is the subject,
    and one predicate is the “calculate[ ] and pay” verb phrase.
    Appellants imply that the prepositional phrase and subordinate clause
    that follow—i.e., “in the same manner and subject to the same terms and
    conditions”—modify that verb phrase, cf. Int’l Primate Prot. League v. Adm’rs of
    Tulane Educ. Fund, 
    500 U.S. 72
    , 79-80 (1991), and because the verb phrase
    “calculate[ ] and pay” is affirmative, it logically does not imply its opposite,
    nonpayment or suspension. Manners and terms and conditions all contemplate
    payment in the first place.    In simpler terms, this reading would be less
    ambiguous if written as follows: “The ORRI shall be calculated and paid in the
    same manner as the landowner’s royalty under the Lease,” persuasively,
    therefore, not contemplating suspension altogether, but just regulating payment.
    Contrastingly, Appellees’ argument points to meaning from a different
    grammatical arrangement, where ORRI itself is modified by the final clause
    “subject to the same terms and conditions as the landowner’s royalty,” hence,
    plausibly, subject even to nonpayment or suspension altogether. In simpler, less
    ambiguous terms: “The ORRI shall be subject to the same terms and conditions
    as the landowner’s royalty under the Lease,” even if that condition is suspension
    altogether. Indeed, had the sentence separated that dependent clause by
    26

    commas—thus: “, and subject to the same terms and conditions,”—Appellees
    would have a stronger argument as to clarity of meaning.
    Given the language of the contracts, however, I cannot say that, for the
    reasons above, the sentence is free of ambiguity.

    EMILIO M. GARZA, Circuit Judge, dissenting:
    I
    Because royalty suspension is a term or condition of royalty payment under
    the lease and the “calculate and pay” clauses of the assignment contracts make
    the overriding royalty interests subject to the same terms and conditions as the
    landowner’s royalty under the lease, I respectfully dissent from the majority’s
    conclusion that the assignment contracts are ambiguous.
    Royalty suspension is unambiguously a term or condition of the
    landowner’s royalty under the lease. The first footnote of the lease states, “This
    lease may be eligible for royalty suspension pursuant to PL 104-58.” PL 104-58
    refers to Public Law No. 104-58, which includes the Outer Continental Shelf Deep
    Water Royalty Relief Act (hereinafter “DWRRA”). According to the DWRRA,
    “suspension of royalties shall be set at a volume of not less than . . . 87.5 million
    barrels of oil equivalent for leases in water depths greater than 800 meters.”
    Pub. L. No. 104-58. It is undisputed that because this lease covered a block of
    property located in water depths greater than 800 meters, the landowner’s
    royalty is suspended on the first 87.5 million barrels of oil produced under the
    lease. The footnote next states, “If eligible, Sections 5 and 6 [providing for
    payment of royalty to Lessor] of this lease instrument will be suspended by 30
    C.F.R. Part 26 . . . .” 30 CFR Part 2601 refers to Outer Continental Shelf Oil and
    Leasing, 
    43 U.S.C. § 1331
     et seq, where the provisions of the DWRRA are
    codified. The footnote thus clearly requires that if the lease is eligible for royalty
    suspension under the DWRRA, Sections 5 and 6 of the lease will be suspended.
    As Sections 5 and 6 of the lease provide instructions for calculating and paying
    the landowner’s royalty under the lease, the footnote unambiguously makes
    1
    Because 30 CFR Part 260 refers to Outer Continental Shelf Oil and Leasing, 
    43 U.S.C. § 1331
     et seq, and 30 CFR Part 26 does not exist, the footnote likely intended to refer to 30
    CFR Part 260.

    No. 11-30038
    royalty suspension a term or condition of payment of the landowner’s royalty
    under the lease.
    The majority, however, finds it ambiguous whether the footnote is a term
    or condition of the lease because the footnote states the lease “may be eligible”
    rather than “shall be eligible.” The majority might be correct if the footnote did
    not also state, “If eligible, Sections 5 and 6 of this lease instrument will be
    superseded by 30 CFR Part 26. . . .” (emphasis added). Black’s Law Dictionary
    defines a “term” as a “contractual stipulation,” BLACK’S LAW DICTIONARY 1608
    (9th ed. 2009), and a “condition” as “a future and uncertain event on which the
    existence or extent of an obligation or liability depends; an uncertain act or event
    that triggers or negates a duty to render a promised performance.” Id. at 333.
    The footnote clearly stipulates that the lease’s provisions for payment of
    royalties are superseded by the DWRRA if the lease is eligible for royalty
    suspension, thus qualifying the lessee’s contractual duty to make royalty
    payments to the United States.         Where the lease is eligible for royalty
    suspension, the footnote negates the lessee’s duty to make royalty payments. As
    such, royalty suspension is a term or condition of the landowner’s royalty under
    the lease.
    The “calculate and pay” clauses in the assignment contracts
    unambiguously make the overriding royalty interests subject to the same terms
    and conditions as the landowner’s royalty under the lease. The “calculate and
    pay” clauses of the Westport Assignment to the Belcher Group state, “The
    overriding royalty interest assigned herein shall be calculated and paid in the
    same manner and subject to the same terms and conditions as the landowner’s
    royalty under the Lease.” The “calculate and pay” clause in the Westport to
    Chevron Assignment contains nearly identical language. The majority holds
    “the ‘calculate and pay’ clauses in the ORRI assignment contracts do not clearly
    and explicitly express the intent that overriding royalty payments shall be
    29
    Case: 11-30038    Document: 00512282396        Page: 30   Date Filed: 06/20/2013
    No. 11-30038
    suspended whenever the U.S. landowner royalties are suspended under the
    DWRRA.” Ante, at 4. The majority thus finds it ambiguous whether the
    assignment contracts apply royalty suspension to overriding royalty interests.
    The plain language of the “calculate and pay” clauses state, however, that
    payment of the overriding royalties must be subject to the same terms and
    conditions as the landowner’s royalty under the lease. The Oxford English
    dictionary defines “subject to” as “dependent or conditional upon.” OXFORD
    ENGLISH DICTIONARY 1427 (10th ed. 1999); see also WEBSTER’S THIRD NEW
    INTERNATIONAL DICTIONARY 2275 (1993) (defining “subject to” as “to be
    conditioned, affected, or modified in some indicated way: having a contingent
    relation to something and usually dependent on such relation for final form,
    validity, or significance”). Thus, the “calculate and pay” clauses clearly and
    explicitly import terms and conditions from the lease as limitations on the scope
    of the overriding royalty rights.
    The majority, emphasizing the longstanding distinction between
    overriding royalty interests and royalties reserved by the landowner, holds it is
    ambiguous whether the “calculate and pay” clauses require application of royalty
    suspension to the overriding royalty interests. Ante at 17–18. The majority
    holds the assignment contracts lack “any clear indication” that royalty
    suspension was intended to apply to the overriding royalty interests. Id. The
    majority is correct that overriding royalty interests are generally paid in
    addition to the usual landowner’s royalty reserved to the lessor. 38 AM. JUR. 2D
    GAS   AND   OIL § 201.   As such, the parties to overriding royalty interest
    assignment contracts are free to set terms for the calculation and payment of
    such interests that are distinct from the terms of payment of the landowner’s
    royalty. See id. Here, however, the assignment contracts contain a clear
    directive that the overriding royalty interests “shall be calculated and paid in the
    same manner and subject to the same terms and conditions as the landowner’s
    30
    Case: 11-30038      Document: 00512282396        Page: 31    Date Filed: 06/20/2013
    No. 11-30038
    royalty under the Lease.” If the parties did not intend the clear import of the
    contracts’ language, they may seek to reform the contract. Agurs v. Holt, 
    95 So. 2d 644
    , 645 (1957). Where, however, the language of a contract is clear and
    unambiguous, we lack the authority to look beyond the four corners of the
    document in search of the parties’ intent. LA. CIV. CODE ANN. art. 2046; Taita
    Chem. Co., v. Westlake Styrene Corp., 
    246 F.3d 377
    , 386 (5th Cir. 2001).
    The majority relies on the fact that it was not certain the lease would
    qualify for suspension of the United States’ landowner royalty under the
    DWRRA at the time the lease at issue in this case was signed as a core source
    of ambiguity in the “calculate and pay” clauses. The majority correctly notes
    that prior to our decisions in Santa Fe Snyder Corp. v. Norton, 
    385 F.3d 884
     (5th
    Cir. 2004), and Kerr-McGee Oil & Gas Corp. v. U.S. Dep’t of Interior, 
    554 F.3d 1082
     (5th Cir. 2009), there was some uncertainty surrounding whether a
    particular lease would qualify for royalty suspension.2             Nonetheless, this
    uncertainty does not translate into ambiguity as to whether the assignment
    contracts require the overriding royalty payments to be subject to the same
    terms and conditions as the landowner’s royalty under the lease. The majority
    assumes that because it was debatable whether royalty suspension would apply,
    the parties to the assignment contracts did not intend royalty suspension to be
    one of the terms and conditions of payment that the overriding royalties are
    subject to. Ante, at 19–20.
    This assumption is unwarranted. The parties to the assignment contract
    may have intended exactly what the plain language of the “calculate and pay”
    2
    See Santa Fe Snyder Corp., 
    385 F.3d at
    892–93 (holding Department of Interior
    regulation restricting the DWRRA’s royalty suspension provisions to fields that had not
    produced prior to enactment of Act was invalid); Kerr-McGee Oil & Gas Corp., 
    554 F.3d at 1083
     (holding Department of Interior regulation requiring payment of royalties on volumes
    less than volume thresholds set by the DWRRA when gas prices reached certain levels was
    invalid).

    No. 11-30038
    clauses state: to make the calculation and payment of the overriding royalties
    subject to the same terms and conditions as the landowner’s royalty under the
    lease. A lack of clarity surrounding when the royalty suspension period would
    apply does not evince a lack of clarity regarding whether the royalty suspension
    period was a term of the lease that the overriding royalties became subject to
    through the “calculate and pay” clauses.
    The majority also concludes the “granting” clauses of the assignment
    contracts make the meaning of the “calculate and pay” clauses ambiguous. The
    granting clause in the Westport Assignment to the Belcher Group states, “The
    undersigned . . . does hereby CONVEY, TRANSFER, ASSIGN, AND SET OVER
    unto the following parties . . . the interest set out opposite their names, as an
    overriding royalty interest payable out of all oil, gas, casinghead gas and
    associated substances produced, saved and marketed from the lease.” (emphasis
    added). The granting clause in the Westport to Chevron Assignment states,
    “The interest assigned herein is subject to . . . an overriding royalty interest
    totaling one percent (1%) of 8/8ths . . . of oil and gas production saved, removed,
    or sold from the Lease.” (emphasis added). The majority implies that if the
    parties intended to require the overriding royalty owners to wait until the lease
    produced 87.5 million barrels of oil before receiving royalty payments, the
    phrasing of the granting clauses would not have explicitly granted the overriding
    royalty owners an interest in all or 8/8ths of production. This is unconvincing.
    Even within the four corners of the assignment contract to the Belcher group,
    the “granting” clause was clearly never meant to be unqualified. In the ORRI
    assignment to the Belcher group, exceptions to royalty due on production are
    listed explicitly in the assignment contract. For example, the assignment
    contract states,
    The overriding royalty interest conveyed shall not, in any event, be
    paid or accrued upon any oil, gas, casinghead gas and other
    hydrocarbon substances used for operation, development or
    32
    Case: 11-30038    Document: 00512282396      Page: 33    Date Filed: 06/20/2013
    No. 11-30038
    production purposes or unavoidably lost; and no overriding royalty
    shall be paid upon gas used in repressuring or recycling operations
    or pressure maintenance operations.
    Moreover, the clear language of the “calculate and pay” clauses in both of the
    assignment contracts qualify the granting clauses by stating that the overriding
    royalty interests are to be calculated and paid “subject to the same terms and
    conditions as the landowner’s royalty under the lease.” (emphasis added).
    The majority also finds the assignment contracts ambiguous because there
    is no reference to royalty suspension in the assignment contracts. The lack of
    the explicit reference to royalty suspension in the assignment contracts proves
    nothing. The “calculate and pay” clauses incorporate the terms and conditions
    of the landowner’s royalty under the lease.          Even under the proposed
    interpretation of the “calculate and pay” clauses that the majority urges, the
    terms and conditions the “calculate and pay” clauses allegedly refer to, the so-
    called “mechanics” of payment, are not explicitly stated in the assignment
    contracts. The fact that the assignment contracts do not both incorporate the
    royalty suspension provision by reference to the terms and conditions of the
    landowner’s royalty under the lease and mention the royalty suspension
    provision by name does not an ambiguity make. Where a term is incorporated
    by reference to an extrinsic agreement, the contract need not also mention the
    incorporated term within the four corners of the contract. See Petrohawk Props.,
    L.P. v. Chesapeake La., L.P., 
    689 F.3d 380
    , 394 (5th Cir. 2012) (holding
    provisions incorporated by reference have identical force and effect to provisions
    within the contract itself).
    The majority also finds support for concluding the “calculate and pay”
    clauses are ambiguous in the fact that the overriding royalty interest owners
    were not a party to the lease. This is puzzling. It is well-established that when
    a contract incorporates terms of an extrinsic agreement by reference, the parties
    to the contract may not rely on the fact that they are not parties to the extrinsic
    33
    Case: 11-30038     Document: 00512282396     Page: 34   Date Filed: 06/20/2013
    No. 11-30038
    agreement as a source of ambiguity. See JS & H Constr. Co. v. Richmond Cnty.
    Hosp. Auth., 
    473 F.2d 212
    , 216 (5th Cir. 1973) (holding subcontractor bound by
    arbitration provision incorporated by reference from the general conditions of
    contract between primary contractor and principal). Despite the majority’s
    assertions to the contrary, the assignment contracts make a clear and
    unambiguous statement that payments of the overriding royalties will be limited
    by the terms and conditions of the landowner’s royalty under the lease.
    Finally, Judge Higginson’s concurring opinion contends the grammatical
    structure of the “calculate and pay” clauses support a finding of ambiguity.
    Although I agree with Judge Higginson that grammatically the clauses are
    susceptible to two different interpretations, under either reading the “calculate
    and pay” clauses unambiguously require application of royalty suspension to the
    overriding royalty interests.     Admittedly, the prepositional phrase and
    subordinated clause “in the same manner and subject to the same terms and
    conditions” may modify the “calculate and pay” verb phrase, as Appellants imply,
    or may modify the subject of the sentence, “The overriding royalty interest,” as
    Total and Statoil urge. Judge Higginson thus asserts it is ambiguous whether
    the “calculate and pay” clauses answer the question of whether the overriding
    royalty owners are entitled to a royalty payment, or merely provide instructions
    for the how to calculate and pay the royalty payments that are due under the
    assignment contract. Regardless of whether the lease is eligible for royalty
    suspension and the payment due is zero or the lease is ineligible for royalty
    suspension and a monetary payment is due, however, royalty suspension is
    inextricably linked to the calculation of the amount of payment due to the
    landowner under the lease. Thus, even if “terms and conditions” modifies
    “calculated and paid,” “terms and conditions” modifies entitlement to the
    royalties vel non.

    Appellants also claim that in the event we reject their interpretation of the
    “calculate and pay” clauses as unreasonable, the original parties to the
    assignment contracts made a mutual mistake in drafting the “calculate and pay”
    clauses. The district court cited two reasons for denying Appellants’ claim for
    reformation. First, the district court held Appellants were attempting “to make
    an end-run around the parole-evidence rule by framing [their] argument as a
    request for reformation.” The district court held that because the assignment
    contracts were unambiguous, parole evidence is not admissible to create
    ambiguity. Second, the district court held that because Total and Statoil, as
    non-parties to the original contracts, were entitled to rely on the integrity of the
    assignment contracts, reformation would impermissibly prejudice Total and
    Statoil. The district court misconstrued Louisiana’s reformation law on both
    points.
    The district court erred by failing to admit Appellants’ extrinsic evidence
    of mutual mistake. When making a claim for reformation the claimant may offer
    parole evidence, not to vary the terms of the written instrument, but to show the
    “writing does not express the true intent or agreement of the parties.” First
    State Bank & Trust Co. of E. Baton Rouge Parish v. Seven Gables, Inc., 
    501 So. 2d 280
    , 289 (La. Ct. App. 1986) (citing Valhi, Inc. v. Zapata Corp., 
    365 So. 2d 867
    , 870 (La. Ct. App. 1978)). “Even if the language utilized is clear and
    unambiguous, parol evidence is admissible to establish that the language does
    not embody the essence of the agreement to which there was mutual assent.”
    Valhi, Inc., 
    365 So. 2d at 870
    . The district court thus erred by refusing to admit
    extrinsic evidence of mutual mistake simply because the contract is
    unambiguous.
    The district court also erred by denying Appellants’ reformation claim on
    the grounds that Total and Statoil, as third parties, were entitled to rely on the

    integrity of the assignment contracts. Under Louisiana law, reformation of a
    contract is impermissible once third parties have relied on the integrity of the
    written instrument. Lewis, 653 So. 2d at 1260. Where, however, the rights of
    third parties would not be prejudiced by reformation, reformation is permissible.
    See Samuels v. State Farm Mut. Auto. Ins. Co., 
    939 So. 2d 1235
    , 1241 (La. 2006);
    M.R. Bldg. Corp. v. Bayou Utils., Inc., 
    637 So. 2d 614
    , 617 (La. Ct. App. 1994)
    (permitting reformation where rights of third party successor in chain of title
    would not be prejudiced by reformation). While Louisiana law is clear that third
    parties are entitled to rely on the integrity of the contracts, third parties must
    have actually relied on the erroneous contract language to be prejudiced. See
    Samuels, 
    939 So. 2d at 1241
     (“There are simply no rules of contractual
    interpretation that would lead us to ignore the clear intent of the parties to the
    fortuitous benefit of a third party insurance company who did not even rely on
    this error in issuing its own policy.”); cf. Am. Elec. Power Co. v. Affiliated FM Ins.
    Co., 
    556 F.3d 282
    , 288 (5th Cir. 2009) (denying claim for reformation where third
    party assumed and relied on contract and there was no indication third party
    would have known of error). The district court thus erred in denying Appellants’
    claim for reformation on the basis that Total and Statoil were entitled to rely on
    the unambiguous contract language.
    III
    Accordingly, I would affirm the district court’s holding that the
    assignment contracts unambiguously apply the royalty suspension provision of
    the DWRRA to the overriding royalty interest owners. I would reverse the
    district court’s grant of summary judgment on Appellants’ claim for reformation,
    but only on the grounds specifically stated by the district court.
    Respectfully, I dissent.
