In this insurance-coverage dispute, plaintiff American Electric Power Company and its subsidiaries (collectively, “AEP”) appeal from the district court’s grant of summary judgment in favor of defendant-insurer Affiliated FM Insurance Company (“Affiliated”). For the following reasons, we affirm the district court’s order.
I
This is an insurance dispute between public-utilities conglomerate AEP and its insurer Affiliated. In 2000, Affiliated issued a policy covering AEP and its subsidiaries from loss due to employee theft or misconduct (the “Affiliated Policy”). Later that year, AEP acquired another utilities conglomerate, Central & Southwest Corporation (“CSW”). The Affiliated Policy was amended to include CSW and its subsidiaries as covered subsidiaries of AEP. Subsequently, AEP discovered losses that occurred in 1999 due to employee theft at two of CSW’s subsidiary limited liability companies (“LLCs”). AEP claimed that these losses were covered under the Affiliated Policy’s “prior loss” *285 clause, which provided coverage for earlier losses if those losses would have been covered under an insurance policy in existence at the time. At the time of the theft, CSW was covered by an insurance policy with Chubb Insurance Group (the “Chubb Policy”). Thus, for purposes of this appeal, the parties agree that the Affiliated Policy covers the losses in 1999 if the Chubb Policy would have extended coverage at that time. After receiving AEP’s claim, Affiliated determined that the 1999 thefts would not have been covered under the Chubb Policy, and thus denied AEP coverage under the Affiliated Policy’s prior loss clause. AEP disagreed and filed suit in federal court.
After discovery, Affiliated moved for summary judgment. The Chubb Policy expressly covered CSW “and any subsidiary corporation now existing or hereafter created or acquired.” (emphasis added). According to Affiliated, this language limited coverage to true corporations and excluded other subsidiary entities like the two LLCs at issue in the 1999 thefts. AEP responded that the term “corporation” was ambiguous and filed affidavits from both CSW and Chubb stating that LLCs were intended to be covered under the general heading of “corporation” in the Chubb Policy. Affiliated moved to strike the affidavits, alleging that they constituted impermissible parol evidence and raising several other evidentiary challenges. The district court determined that the term “corporation” was unambiguous and did not include LLCs. Thus, the court granted summary judgment and struck the affidavits as impermissible parol evidence.
AEP subsequently filed a Rule 59(e) motion for rehearing, claiming inter alia that the district court should reform the Chubb Policy to match the original intent of CSW and Chubb to include LLCs. The district court declined to reform the Chubb Policy and entered a final order granting summary judgment. AEP now appeals this final order, claiming that the district court erred in (1) finding the policy unambiguous and (2) declining to reform the policy.

A
AEP first contends that the district court erred in finding the term “corporation” to be unambiguous and thereby excluding AEP’s affidavits containing relevant parol evidence.

‘We review
de novo
the court’s grant of summary judgment. We also review
de novo
the interpretation of a contract, including the question of whether the contract is ambiguous.”
Advocare Intern. LP v. Horizon Labs., Inc.,
Under Louisiana law,

“[interpretation of a contract is the determination
*286
of the common intent of the parties.” La. Civ.Code Ann. art. 2045. This involves a two-step process: The court must first look to the plain text of the contract to determine whether its meaning is clear and unambiguous.
See
La. Civ.Code Ann. art. 2047 (“The words of a contract must be given their generally prevailing meaning.”). “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.” La. Civ.Code Ann. art. 2046;
see also Abshire v. Vermilion Parish Sch. Bd.,
AEP contends that the district court erred in finding the policy unambiguous. According to AEP, the term “subsidiary corporation” can be reasonably interpreted to include LLCs. AEP argues that the common understanding of “corporation” extends beyond its legal definition and includes unincorporated entities like LLCs. For support, AEP points to numerous judicial and legal references to LLCs as “limited liability corporations.” In addition, AEP argues that the term must be construed in light of the overarching policy. AEP contends that interpreting the Chubb Policy to exclude LLCs would create an “absurd consequence — an inexplicable gap in insurance coverage” among CSW’s subsidiary entities. 3
We find that the district court did not err in finding the Chubb Policy unambiguous and excluding parol evidence. The generally prevailing meaning of the term “corporation” does not include LLCs.
See
La. Civ.Code Ann. art. 2047 (“The words of a contract must be given their generally prevailing meaning.”). LLCs are statutory creatures defined in part by their contrast to corporate entities.
See Harvey v. Grey Wolf Drilling Co.,
In sum, the term “corporation” is “clear and explicit and lead[s] to no absurd consequences” in the context of the Chubb Policy. See La. Civ.Code Ann. art. 2046. Accordingly, the district court did not err in finding the policy unambiguous and excluding parol evidence of the parties’ intent.
B
AEP next contends that the district court erred in refusing to reform the Chubb Policy to include LLCs. AEP raised this reformation argument for the first time in its Rule 59(e) motion for reconsideration. Because the district court considered the merits of the Rule 59(e) motion and still granted summary judgment, we review the reformation issue under the familiar summary-judgment standard of
de novo. See Templet v. HydroChem Inc.,
Reformation is “an equitable remedy used to correct errors or mistakes” in contracts.
See WMC Mortg. Corp. v. Weatherly,
Here, the district court refused to reform the Chubb Policy because Affiliated — who was not a party to the original agreement — had no knowledge of any error in the Chubb Policy when it later assumed liability through the Affiliated Policy. On appeal, AEP contends that reformation is nevertheless appropriate and argues that the
Samuels
decision controls the instant case. In
Samuels,
the Louisiana Supreme Court reformed a clerical error in an insurance contract even though reformation worked to the detriment of a third party.
Samuels,
We find that the district court did not err in refusing to reform the Chubb Policy. This case is distinguishable from
Samuels
on two dispositive grounds. First,
Samu-els
involved a third party who did not assume or rely on the original contract in any manner.
Second, the use of the term “corporation” is not the type of “error” that reformation is intended to remedy.
Samuels
involved an obvious clerical mistake that lead to the inclusion of an unintended and inaccurate policy number.
See Samuels,
In sum, we find that there is a significant difference between an obvious clerical error and the alleged “hidden meaning” in a contract assumed by an unwitting third party. Equity may counsel relief for the former, but it does not for the latter. Accordingly, the district court correctly declined to reform the unambiguous text of the Chubb Policy.
Ill
For the foregoing reasons, the district court’s order granting summary judgment is AFFIRMED.
Notes
. The district court did not resolve Affiliated’s other evidentiary challenges to the affidavits. Accordingly, we address only their exclusion as impermissible parol evidence to an unambiguous contract.
. This action was filed in the Middle District of Louisiana pursuant to federal diversity jurisdiction.
See
28 U.S.C. § 1332. Accordingly, we are bound to apply the substantive law, including the conflict-of-law rules, of the forum state Louisiana.
See Klaxon Co. v. Stentor Elec. Mfg. Co.,
. AEP raises numerous other arguments relating to parol evidence of the parties intent to include LLCs. However, parol evidence cannot be used to create an ambiguity in an otherwise unambiguous contract.
See Abshire,
. When a party seeks to reform a policy so as to provide coverage for a “substantially different and greater risk” than expressly covered, the party must demonstrate a mutual error by clear-and-convincing evidence.
