Six Flags, Inc. appeals the district court’s order granting summary judgment in favor of seven of its property insurers. The parties primarily contest whether a sublimit in the relevant insurance policies that applies “as respects Flood” limits the insurers’ liability for loss and damage at Six Flags’s New Orleans theme park that resulted from flooding associated with Hurricane Katrina. The district court held that the sublimit applies to the flood loss and granted partial summary judgment for the insurers. We affirm in part, reverse in part, and remand.
I. FACTUAL AND PROCEDURAL BACKGROUND
Plaintiff-appellant Six Flags, Inc. brings this suit against defendants-appellees Westchester Surplus Lines Insurance Co. (‘Westchester”); Arch Specialty Insurance Co. (“Arch”); Great Lakes Reinsurance (UK) PLC (“Great Lakes”); Commonwealth Insurance Co. (“Commonwealth”); Axis Specialty Insurance Co. (“Axis”); Continental Casualty Co. (“Continental”); and Liberty Corporate Capital, Ltd. (“Liberty”) 1 (collectively, the “Excess Insurers”). Six Flags asserts that the Excess Insurers insured it against loss that Hurricane Katrina-related flooding caused to its New Orleans theme park.
Six Flags obtained multi-layered, all-risk, first-party property insurance for its domestic theme parks for the period of June 15, 2004, to November 1, 2005. Six Flags’s agent, Marsh, Inc., generated and submitted broker manuscript forms requesting specific types of coverage, clauses, and terms to various insurers. Marsh placed insurance contracts with the Excess Insurers and other insurance companies that resulted in policies totaling $450 million in combined limits for all insured losses. The policies provided four distinct layers of coverage: (1) a primary layer with $25 million in limits; (2) a first excess layer with $50 million in limits; (3) a second excess layer with $125 million in limits; and (4) a third excess layer with $250 million in limits. 2 Six Flags paid an annual premium of $5,716,927 for this coverage.
The Excess Insurers sold policies to Six Flags (the “Excess Policies”) covering all risks within the first and second excess layers — the $25 million to $200 million range — the only layers at issue in this case. 3 The Excess Policies contain a number of clauses that are relevant to this appeal. They insure against all risks, 4 subject to certain limits and deductibles. One such sublimit is “applicable to all loss or damage ... per occurrence and in the term aggregate as respects Flood at any location in a Flood Zone A or V as designated by ... the Federal Emergency Management Agency” (the “Flood sublim *952 it”). 5 The Excess Policies also contain deductibles, including separate deductibles for the perils of Flood and of a Named Storm. 6
Most of the Excess Policies define “Flood” as:
1) A general and temporary condition of partial or complete inundation of normally dry land areas from:
(a) the overflow of inland or tidal waters;
(b) the unusual and rapid accumulation or runoff of surface waters from any source; or
* * *
2) the release of water impounded by a dam;
3) water that backs up or flows from a sewer, drain or sump;
Loss or damage caused by flood shall include all covered loss or damage to covered property resulting directly or indirectly from flood, except loss or damage from resulting Fire, Explosion and Sprinkler Leakage or loss or damage otherwise excluded by this policy.
The Commonwealth policy, however, contains an endorsement (the “Commonwealth Flood definition endorsement”) that replaces the definition of Flood with the following statement:
The term “flood” is defined as loss or damage caused by waves, tidal water or tidal wave, overflow of streams or other bodies of water, or spray from any of the foregoing, all whether driven by wind or not. Loss resulting from, contributed to or aggravated by a “flood” caused by a peril not otherwise excluded under this policy shall not be considered in application of the policy “flood” limit or deductible provisions.
Finally, the policies lump together loss within a 72-hour window resulting from a single event into an occurrence for adjusting claims — i.e., for application of sublimits and deductibles. Relevant to this appeal, *953 the policies define a Weather Cat Occurrence as follows:
All loss or damage occurring during a period of 72 hours which is caused by or results from a storm or weather disturbance which is named by the National Weather Service or any other recognized meteorological authority.
Storm or weather disturbance includes all weather phenomenon associated with or occurring in conjunction with the storm or weather disturbance, including, but not limited to Flood, wind, hail, sleet, tornadoes, hurricane or lightning.
The Excess Policies were effective on August 29, 2005, when Hurricane Katrina, a storm named by the National Weather Service, struck the Gulf Coast. Hurricane Katrina caused heavy damage to and interrupted the operations of the Six Flags New Orleans theme park located at 12301 Lake Forest Boulevard, New Orleans, Louisiana. Flooding lasting several weeks caused much of the damage to the theme park, although high winds also contributed. Six Flags New Orleans sits within a Federal Emergency Management Agency designated Flood Zone A.
Six Flags submitted losses totaling $150 million to its insurers. Six Flags’s primary-layer insurers, including IRI, paid $25 million, exhausting that layer of coverage. The Excess Insurers’ adjustor, however, capped their liability at $2.5 million pursuant to the Flood sublimit. The second-layer Excess Insurers paid Six Flags that $2.5 million plus compensation for certain losses resulting from wind damage.
After unsuccessfully protesting the applicability of the Flood sublimit, Six Flags filed the present lawsuit in the district court. It sought a declaratory judgment that the Flood sublimit did not apply to its Hurricane Katrina-related losses and claimed that the Excess Insurers breached the Excess Policies by applying the Flood sublimit to damage covered by the separate peril of a Named Storm. The Excess Insurers filed motions for partial summary judgment pursuant to Rule 56 of the Federal Rules of Civil Procedure, which Six Flags opposed. Six Flags also requested the opportunity to engage in additional discovery pursuant to Rule 56(f) of the Federal Rules of Civil Procedure.
The district court granted the Excess Insurers’ motions for partial summary judgment and denied Six Flags’s discovery request. The district court concluded that the Flood sublimit is unambiguous: it “specifically limit[s] recovery for Flood in Zone A or V to its respective dollar value
per occurrence.” Six Flags Inc. v. Westchester Surplus Lines Ins. Co.,
Because the Excess Policies were unambiguous, the district court declined to review extrinsic evidence that Six Flags presented showing that the insurers did not intend the Flood sublimit to apply to storm loss and therefore denied Six Flags’s Rule 56(f) motion. On April 7, 2008, the court *954 entered final judgment for the Excess Insurers. 7 Six Flags now appeals.

C. The Excess Policies
1. Excess Policies Other Than the Commonwealth Policy
The contract provisions in the non-Commonwealth Excess Policies have only one reasonable meaning: the Flood sub-limit caps the liability of the Excess Insurers at $2.5 million for all loss or damage per occurrence, including a Weather Cat Occurrence, as respects Flood. The Excess Policies insure against “all risks of direct physical loss of or damage to covered property” subject to specific exclusions not applicable in this case. Within that all-risks coverage, certain limits and sublimits set the Excess Insurers’ maximum liability, generally on a per occurrence basis. The Flood sublimit applies “per occurrence in the term aggregate as respects Flood at any location in Flood Zone A or V.” The non-Commonwealth Excess Policies define loss from Flood to “include all covered loss or damage to covered property resulting directly or indirectly from ... inundation of normally dry land areas.” The Excess Policies also contain deductibles that apply on a per occurrence basis. The relevant deductible in this case is 3% of the damage for “the peril of a Named Storm.” The parties agree that “Named Storm” and “Weather Cat” are interchangeable terms.
The Excess Policies define “occurrence” in order to explain when sublimits or the deductible apply
8
— not to exclude the applicability of a particular sublimit.
Cf. Northrop Grumman Corp. v. Factory
*956
Mut. Ins. Co.,
Six Flags, however, argues that the Flood sublimit does not apply to Flood loss in a Weather Cat Occurrence because a Named Storm is a distinct peril not subject to the Flood sublimit. 10 As noted above, the Excess Policies provide a deductible that applies to “the peril of a Named Storm.” The term “peril” has an industry usage. A “peril” is “[t]he cause of a risk of loss to person or property; esp., the cause of a risk such as fire, accident, theft, forgery, earthquake, flood, or illness.” Black’s Law Dictionary 1174 (8th ed.2004). To Six Flags, because a Weather Cat Occurrence undisputedly corresponds to a Named Storm, it offers a “one-stop shop” for insuring all loss resulting from a hurricane — in other words, the Weather Cat Occurrence subsumes all of the other perils defined therein and is subject only to sublimits and deductibles expressly addressed to it. While we have no doubt that the parties could have agreed to such a provision, we cannot reasonably interpret the Weather Cat Occurrence definition to have this meaning.
Six Flags’s proposed construction ignores the language of the Excess Policies and disregards the express purpose of defining an occurrence. To start, Six Flags’s argument fails to acknowledge that the Flood sublimit applies to loss or damage per occurrence as respects Flood, not “per *957 Flood Occurrence” or “as respects the peril of Flood.” Without reference- to the terms of the Excess Policies, Six Flags nonetheless asks us to inferentially foreclose the applicability of the “applicable, to all loss or damage” Flood sublimit to the “all loss or damage” Weather Cat Occurrence. Reviewing the provisions of the Excess Policies, we conclude that, to give meaning both to the definition of Flood and to “per occurrence” in the Flood sub-limit, the only reasonable interpretation is that the Flood sublimit applies across different types of occurrences to loss or damage that falls under the definition of Flood. 11
In addition, Six Flags’s reading avoids recognizing that the definition of an occurrence, which groups certain losses for adjustment purposes, is distinct from the concept of a peril, which is the cause of the loss. Six Flags’s proposed construction would transform the definition of a Weather Cat Occurrence into the definition of a Named Storm peril by cross-referencing the non-definitional mention of that peril in the deductible that applies to a Weather Cat Occurrence. We conclude that such a result would conflate the two distinct terms — and is too tenuous to provide a reasonable alternative meaning to the Excess Policies.
See Northrop Grumman Corp.,
Finally, Six Flags asks us to interpret the Excess Policies by applying a presumption in favor of coverage. Article 2056 of the Louisiana Civil Code provides: “In case of doubt that cannot be otherwise resolved, a provision in a contract must be interpreted against the party who furnished its text. A contract executed in a standard form of one party must be interpreted, in case of doubt, in favor of the other party.” Because the insurer typically furnishes the text of a policy to the insured, often on its standard form, the Louisiana courts have repeatedly interpreted ambiguous provisions against the insurer and in favor of the insured.
See, e.g., Tunstall v. Stierwald,
These presumptions, however, do not apply to the Excess Policies in this case. First, article 2056 and its derivative rules of construction are inapplicable to an unambiguous insurance contract.
Sharp v. Fed. Sav. & Loan Ins. Corp.,
Second, the court has previously determined that, under Louisiana law, the presumption does not apply where the insured is a sophisticated commercial entity that itself drafts or utilizes its agent to secure desired policy provisions.
See McDermott Int’l, Inc. v. Lloyds Underwriters of London,
*959 Overall, we conclude that the non-Commonwealth Excess Policies unambiguously establish that the Flood sublimit applies to loss and damage as respects Flood caused by, associated with, or occurring in conjunction with Hurricane Katrina.
2. The Commonwealth Policy
Six Flags argues that the Commonwealth Flood definition endorsement evidences the Excess Insurers’ intent to prevent the applicability of the Flood sub-limit to loss caused by a Named Storm. In its only relevant departure from the other Excess Policies, the Commonwealth Flood definition endorsement replaces the language to define the term “Flood.” It states that:
The term “flood” is defined as loss or damage caused by waves, tidal water or tidal wave, overflow of streams or other bodies of water, or spray from any of the foregoing, all whether driven by wind or not. Loss resulting from, contributed to or aggravated by a “flood” caused by a peril not otherwise excluded under this policy shall not be considered in application of the policy “flood” limit or deductible provisions.
Six Flags argues that this endorsement clarifies, for the Commonwealth policy as well as for the non-Commonwealth Excess Policies, that Flood caused by the peril of a Named Storm is not considered in the application of the Flood sublimit. The Excess Insurers counter that Commonwealth’s definition of Flood means only that loss caused by other perils is not subject to the Flood sublimit and the inclusion of the phrase “all whether driven by wind or not,” which has been universally interpreted to include hurricane-related flooding, would be rendered ineffective.
We conclude that the Commonwealth Flood definition endorsement creates an ambiguity in the Commonwealth policy but not the non-Commonwealth Excess Policies. One reasonable interpretation of the endorsement, when considered with the entire Commonwealth policy, is that loss resulting from a flood caused by a peril (such as a Named Storm) is not subject to the Flood sublimit. The Excess Insurers do not dispute that Hurricane Katrina was a Named Storm and cannot (at least at this time) dispute that Hurricane Katrina caused the flooding at issue here. Thus, under this interpretation, the Flood sub-limit would not apply to loss resulting from the flood at the Six Flags New Orleans theme park caused by Hurricane Katrina.
The Excess Insurers counter that Commonwealth’s re-wording was meant only to clarify that loss caused by a separate peril is not subject to the Flood sublimit when that loss also resulted from Flood.
13
Thus, the Excess Insurers argue that “caused by
*960
a peril” modifies “loss” — for Six Flags, “caused by a peril” modifies “flood.” Even if this alternative interpretation is reasonable, which we do not decide at this time, the existence of two reasonable alternative interpretations would create an ambiguity in the Commonwealth policy.
See Bonin,
The Excess Insurers also contend that our interpretation of the Commonwealth policy would render ineffective the phrase “all whether driven by wind or not.” We have interpreted similar language to exclude coverage for hurricane-caused flooding where the policies at issue expressly deny coverage for flooding caused or contributed to by other perils.
See Tuepker,
Six Flags asserts that this conclusion extends to the non-Commonwealth Excess Policies. In particular, it argues that the definition of Flood in the non-Commonwealth Excess Policies should be read in light of the definition contained in the Commonwealth Flood definition endorsement. 17 The non-Commonwealth Excess Policies do not contain a provision that similarly conditions the applicability of the Flood sublimit on the peril causing the flood. Thus, to the extent that the Commonwealth policy differs from the non-Commonwealth Excess Policies, Six Flags asks us to modify the non-Commonwealth Excess Policies to find an ambiguity. We decline to interpret the non-Commonwealth Excess Policies by reference to the Commonwealth Flood definition endorsement. Louisiana statutory rules require that:
No agreement in conflict with, modifying, or extending the coverage of any contract of insurance shall be valid unless it is in writing and physically made a part of the policy or other written evidence of insurance, or it is incorporated in the policy or other written evidence of insurance by specific reference to another policy or written evidence of insurance.
La.Rev.Stat. Ann. § 22:867. Thus, our inquiry focuses on whether the Excess Policies incorporate the Commonwealth policy or Commonwealth Flood definition endorsement by specific reference.
See Ins. Co. of N. Am. v. Bd. of Comm’rs of Port of New Orleans,
D. Extrinsic Evidence And The Denial of Plaintiff’s Rule 56(f) Motion
Six Flags asks us to consider extrinsic evidence in order to discern the intent of the parties. Extrinsic evidence includes “the nature of the contract, equity, usages, the conduct of the parties before and after formation of the contract, and of other contracts of a like nature between the same parties.” La. Civ.Code Ann. art. 2053. Extrinsic evidence may only be used to clarify ambiguity, not to create an ambiguity in an otherwise clear contract.
See Campbell v. Melton,
Six Flags finally argues that the district court erred by denying its request to conduct additional discovery pursuant to Rule 56(f). 20 Six Flags seeks additional extrin *963 sic evidence regarding the Excess Insurers’ and IRI’s intentions that the policies would provide full coverage for loss or damage from a hurricane. The district court concluded that it did not need to grant Six Flags’s motion because the Excess Policies were unambiguous; thus, the information Six Flags sought to discover was not essential to deciding the partial motion for summary judgment.
We affirm as to the non-Commonwealth Excess Insurers. “The trial judge’s decision to curtail discovery is granted great deference and, thus, is reviewed under an abuse of discretion standard.”

III. CONCLUSION
For the foregoing reasons, we AFFIRM in part, REVERSE in part, and REMAND. We AFFIRM the district court’s entry of judgment for Westchester Surplus Lines Insurance Co.; Arch Specialty Insurance Co.; Great Lakes Reinsurance (UK) PLC; Axis Specialty Insurance Co.; Continental Casualty Co.; and Liberty Corporate Capital, Ltd. We REVERSE the district court’s entry of judgment for Commonwealth Insurance Co. and REMAND for proceedings between Six Flags and Commonwealth consistent with this opinion. Costs incurred by the non-Commonwealth Excess Insurers shall be borne by Six Flags. Six Flags and Commonwealth shall bear their own costs.
Notes
. Liberty is the lead underwriter of Syndicate 190 at Lloyd's of London and the named defendant for that syndicate.
See Corfield v. Dallas Glen Hills, LP,
. Industrial Risk Insurers ("IRI”) was the principal insurer in the primary layer. Although it is not a party in this case, Six Flags presents evidence and argument regarding IRI's role in drafting clauses at issue here.
. The insurers in the first excess layer were Westchester, Arch, and Great Lakes. Those in the second excess layer were Commonwealth, Axis, Continental, and Liberty.
. Each of the Excess Policies provides that “[t]his policy insures against all risk of direct physical loss of or damage to covered property while on a described premises herein.”
. The full text of the Flood sublimit provides:
3) LIMITS OF LIABILITY
B) Sublimits (applicable to all loss or damage):
The liability of [the Excess Insurer] resulting from loss or damage insured against herein shall not exceed:
4) [$2,500,000 for first-layer excess policies; $27,500,000 for second-layer excess policies] per occurrence and in the term aggregate as respects Flood at any location in a Flood Zone A or V as designated by the Army Corp of Engineers or the Federal Emergency Management Agency (FEMA).
According to FEMA, lands located in Flood Zone A are at high risk of flooding due to their proximity to bodies of water such as lakes and rivers, and lands located in Flood Zone V are at high risk for coastal flooding from tides and waves. Other sublimits apply per occurrence for Debris Removal and Expediting Expenses and per occurrence as respects Civil or Military Authority, Ingress/Egress, Leader Property, Leasehold Interest, Rental Value, Royalties, Service Interruption, and Valuable Papers & Records.
. The Excess Policies state, in relevant part:
5) PRIMARY POLICY DEDUCTIBLES
All losses, damages or expenses arising out of any one occurrence shall be adjusted as one loss, and from the amount of such adjusted loss shall be deducted:
E) 5% of the combined Property Damage and Time Element Value at all or part of locations situated within the 100 year recurrence interval for the peril of Flood (with the exception of Six Flags Fiesta Texas), subject to a minimum deductible of $1,000,000 of the deductible in Section A, whichever the greater.
H) 3% of the combined Property Damage and Time Element Values at all locations for the peril of a Named Storm, subject to a Minimum deductible no less than the deductible in Section A.
. After the district court entered partial summary judgment, Six Flags filed an unopposed motion under Rule 54(b) of the Federal Rules of Civil Procedure for entry of final judgment or, in the alternative, under 28 U.S.C. § 1292(b) for certification of interlocutory appeal. The district court granted Six Flags’s Rule 54(b) motion and ordered the remaining coverage disputes to be resolved by an appraiser in private settlement.
. The Excess Policies provide for the applicability of one deductible “[i]f loss arising out of one Occurrence is subject to any combination of deductibles." As the Excess Policies do not similarly provide a rule for the applicability of a single sublimit but expressly state that each is "applicable to all loss or damage,” multiple sublimits may apply to each occurrence. Thus, the losses for, e.g., Debris Removal and Rental Value are separately limited.
. Precedent applying Mississippi, Texas, and New York law shows that definitions of occurrences are often used to define the applicability of a sublimit or deductible.
See, e.g., Madison Materials Co. v. St. Paul Fire & Marine Ins. Co.,
. A brief reference in its Reply Brief to the doctrine of "efficient proximate cause” aside, Six Flags does not argue that its loss was not caused by flood — nor can it in light of
Tuepker v. State Farm Fire & Casualty Co.,
. Six Flags’s proposed interpretation would suggest implausible outcomes regarding the applicability of other sublimits as well. Notably, the Excess Policies do not distinguish between sublimits that apply to the causes of loss and those that apply to the types of loss. Thus, construing the policies as Six Flags asks would suggest the remarkable result that the sublimits for, e.g., Debris Removal and Service Interruption would not apply to a Weather Cat Occurrence, despite being significant sources of loss in the' aftermath of a hurricane.
. We give no credence to Six Flags’s citation to Pinnacle Entertainment, Inc. v. Allianz Global Risks U.S. Insurance Co., No. 2:06-CV-935, slip op. (D.Nev. Mar. 26, 2008), an unpublished district court decision provided in Six Flags’s Record Excerpts. That court in Pinnacle concluded that Flood and Weather Cat Occurrence were distinct perils based on a definitional section in the insurance contract in that case. The court expressly distinguished the contract at issue here as described by the district court below.
. The Excess Insurers also argue that the Flood sublimit applies to all flood loss, whether hurricane-related or otherwise, citing
Altru Health System v. American Protection Insurance Co.,
In
Altru,
the Eighth Circuit held that loss due to business interruption caused by a flood that also resulted in a civil authority order closing the insured's business was subject to the flood sublimit.
Similarly, in
Gilbert/Robinson,
the Missouri Court of Appeals held that an endorsement that extended policy coverage to business interruption loss was subject to the limit defined in an endorsement that provided protection against the peril of flood because business interruption loss was expressly subject to the limit that controlled the applicable per premises loss contained in the flood endorsement and without that endorsement, the premises would not have been insured against the peril of flood.
Overall, while
Altru, Gilbert/Robinson,
and
Arjen
reach outcomes that the Excess Insurers desire to have replicated here, they stand for nothing more than the application of the clear policy language of their respective contracts.
See generally La. Ins. Guar. Ass'n,
. The Excess Insurers also argue that Hurricane Katrina was not a separate peril. While they reiterate, as we have concluded above, that the Weather Cat Occurrence provision defines an occurrence, not a peril, they do not dispute that a Named Storm is independently and expressly labeled a peril. Thus, the question is not whether the Flood sublimit applies to Flood aggregated within a Weather Cat Occurrence, which it undoubtedly does; instead, the question is to what extent the peril of a Named Storm — here, Hurricane Katrina — caused the flood that resulted in the loss claimed by Six Flags, thus rendering the Flood sublimit inapplicable pursuant to the Commonwealth Flood definition endorsement. For the present appeal, the parties have not disputed that the flooding was caused by Hurricane Katrina.
. The Excess Insurers have not briefed whether the phrase "all whether driven by wind or not” is rendered ineffective for any other reason. During oral argument, they did contend that all flooding is caused by other perils, thus an interpretation favoring Six Flags would render the entire Flood sublimit ineffective. We do not subscribe to this proposition. The Excess Policies label Flood as a peril, thus evidencing that Flood, in many *961 circumstances, is the independent cause of certain losses without causation by another peril.
. We do not proceed to select between the competing interpretations at this time for three reasons. First, Six Flags did not move for summary judgment in the district court. Second, because the district court concluded the Excess Policies were unambiguous, it terminated Six Flags's discovery and, moreover, did not review the existing extrinsic summary judgment evidence. Third, as noted above, we do not apply a presumption of coverage in favor of a sophisticated corporation represented by an insurance broker and, in any case, it is first appropriate to discern the intent of the parties through extrinsic evidence.
See In re Katrina Canal Breaches Litig.,
. Outside of the use of extrinsic evidence related to IRI's policy, the text of which is not in the record, Six Flags has not briefed the relevance of the IRI policy or any difference in its text.
. While some precedent suggests that the court may construe the Excess Policies together, it ultimately cautions against doing so where we would need to treat the policies as one contract.
See, e.g., Northrop Grumman Corp.,
. Six Flags did not file a cross-motion for summary judgment in the district court, and the district court specifically refused to consider any of Six Flags's extrinsic evidence after it concluded that the Excess Policies are unambiguous.
. Rule 56(f) provides:
If a party opposing the motion shows by affidavit that, for specified reasons, it cannot present facts essential to justify its opposition, the court may:
(1) deny the motion;
(2) order a continuance to enable affidavits to be obtained, depositions to be taken, or other discovery to be undertaken; or
(3) issue any other just order.
