HAYNES, Circuit Judge:

Tesoro Corporation and Tesoro Refining & Marketing Company, LLC

(“Tesoro Refining”) (collectively, the “Tesoro Parties”) appeal the summary 

judgment granted in favor of AIG Specialty Insurance Company, formerly 

known as Chartis Specialty Insurance Company (“Chartis”). We AFFIRM.

I. Facts

The Golden Eagle Refinery in Martinez, California, has been subject to 

a prolonged series of federal and state environmental remediation orders. In 

2000, Tosco Corporation (“Tosco”) sold the refinery to Ultramar Diamond 

Shamrock (“Ultramar”) and provided indemnity for $50 million of remediation 

costs to cover preexisting environmental issues. Ultramar, based in Texas, 

also purchased $100 million excess coverage from Chartis (the “Chartis policy”)

via an insurance broker, Marsh. Ultimately, Ultramar began negotiating with 

Tesoro Corporation and agreed to sell the refinery to Tesoro Refining. The 

purchase and sale agreement specified that Ultramar was to assign the Tosco 

indemnities, and to either secure an endorsement to the Chartis policy adding 

the new company as an additional insured or assign the Chartis policy directly. 

This litigation concerns the transfer of the Chartis policy from Ultamar. 

Chartis did provide the transfer endorsement—but the endorsement named 

Tesoro Corporation as the new named insured. By contrast, Tesoro Refining, 

its subsidiary, was the actual purchaser of the refinery. Chartis contends that 

it acted upon instructions that listed only Tesoro Corporation as the named 

insured.1 Indeed, Tesoro Corporation has a corporate practice of naming the 

 

1 The policy listed the “Named Insured” on the front page and defined “Insured” in 

the body of the policy as “the Named Insured, and any past or present director, officer, 

partner, or employee thereof, including a temporary or leased employee, while acting within 

the scope of his or her duties as such.” This definition, then, did not include subsidiaries. 

Effective May 17, 2002, Chartis sent an endorsement changing the Named Insured to “Tesoro 

Petroleum Corporation” (now known as Tesoro Corporation) and adding Valero Energy 

Corporation as an additional insured. Tesoro Refining was not mentioned.

parent on insurance policies but takes the position in this litigation that both 

companies should have been insured. The Tesoro Parties further maintain 

that all of the parties to the deal shared a common understanding and 

intention that the policy should be written such that it covered Tesoro Refining. 

Soon after the refinery transaction took place, Tesoro Refining sued 

Tosco for fraud contending that Tosco had concealed the severity of the 

environmental liabilities present at the refinery. Tosco argued that Tesoro 

Refining’s decision to secure extensive excess insurance coverage showed that 

it had not detrimentally relied on Tosco’s purportedly inaccurate 

representations regarding the environmental issues at the refinery. In 

response, Tesoro Refining argued that its insurance coverage could not defeat 

its fraud claim, and that, since Tosco had not paid the premium on the policies 

and was not itself a named insured, there was no basis for it to even raise the 

existence of the coverage. 

The Tosco/Tesoro Refining dispute stretched from 2003 until 2007. As 

Tosco and Tesoro Refining drew near a settlement, Tesoro sent a letter to 

apprise Chartis of the progress of the litigation. Chartis responded with a 

reservation of rights letter that acknowledged the matter as a potential claim. 

That letter identified “Tesoro Petroleum Corporation” (Tesoro Corporation’s 

prior name) as the named insured and stated that coverage would be provided

only if the insured were legally obliged to pay for cleanup costs. 

Tesoro Refining settled the Tosco litigation in March 2007, receiving 

$58.5 million from Tosco’s successor, ConocoPhillips. In October 2009, Chartis 

received a formal demand for coverage in a letter written on “Tesoro 

Corporation” letterhead and identifying “Tesoro Petroleum Corporation” as the 

named insured. This letter indicated that Tesoro Refining was the buyer of 

the refinery and the party that owed cleanup liabilities. The Tesoro letter 

explained the conclusion of the Tosco litigation, outlined various expenditures

on environmental cleanup, and demanded that Chartis pay under the policy. 

Chartis acknowledged the demand and indicated that it would investigate the 

claims. That investigation proceeded slowly, and the parties eventually filed 

suit. The Tesoro Parties initially sued in California, with Chartis filing a 

declaratory judgment action in Texas. Both cases were later consolidated into 

one action in federal district court in San Antonio. 

It was in this litigation that the matter of which entity was insured 

under the Chartis policy came to the fore, with Chartis contending that it owed 

coverage only to Tesoro Corporation. In 2012, the Tesoro Parties sought 

reformation and also sued for breach of contract on a “third-party beneficiary” 

claim under California law (assuming arguendo that Tesoro Refining was not 

a named or additional insured under the policy). The district court applied 

Texas law to the third-party beneficiary claim and concluded that it failed; 

alternatively, it concluded also that California law would not offer relief. In 

addition, the court concluded that the reformation claim was barred by the 

Texas four-year statute of limitations (and, in the alternative, the California 

three-year statute) because, at a minimum, the Tesoro Parties should have 

discovered the alleged mistake during the mid-2000’s Tesoro/Tosco litigation. 

Thus, the action filed in 2012 was barred. Ultimately, the district court 

entered judgment in Chartis’s favor, and the Tesoro Parties timely appealed.2

II. Discussion

A summary judgment is reviewed de novo, applying the same standard 

on appeal that the district court applied. Rogers v. Bromac Title Servs., L.L.C., 

755 F.3d 347, 350 (5th Cir. 2014). Summary judgment is proper “if the movant 

shows that there is no genuine dispute as to any material fact and the movant 

is entitled to judgment as a matter of law.” FED. R. CIV. P. 56(a). “A genuine 

 

2 We have appellate jurisdiction under 28 U.S.C. § 1291, and the district court had 

diversity jurisdiction over the underlying case.

dispute as to a material fact exists ‘if the evidence is such that a reasonable 

jury could return a verdict for the nonmoving party.’” Rogers, 755 F.3d at 350 

(quoting Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 248 (1986)). The court 

is to view the evidence and reasonable inferences drawn from the evidence in 

the light most favorable to the nonmoving party, here the Tesoro Parties. 

Hernandez v. Velasquez, 522 F.3d 556, 560 (5th Cir. 2008). We can affirm a 

summary judgment for any reason supported by the record and presented to 

the district court, even if the district court did not rely on that reason. See id.

A. Third-Party Beneficiary 

 The parties agree that Texas law does not recognize a third-party 

beneficiary claim that would permit Tesoro Refining to recover here. The 

Tesoro Parties argue that California law governs and that it provides relief for 

Tesoro Refining. Because the Tesoro Parties concede that they would not 

prevail under Texas law and therefore do not appeal the district court’s 

resolution of that portion of the issue, we analyze only California law to see 

whether it sustains the claimed relief the Tesoro Parties seek.3 

California, like most states, holds that a contract should be interpreted 

so as to “give effect to the mutual intention of the parties as it existed at the 

time of contracting . . . .” CAL. CIV. CODE § 1636 (West). Further, “[w]hen a 

contract is reduced to writing, the intention of the parties is to be ascertained 

from the writing alone, if possible . . . .” CAL. CIV. CODE § 1639 (West); see also, 

e.g., Wolf v. Walt Disney Pictures & Television, 76 Cal. Rptr. 3d 585, 601 (Cal. 

Ct. App. 2008) (“Ordinarily, the objective intent of the contracting parties is a 

 

3 The parties dispute which state’s laws apply: California or Texas. We conclude that 

it is unnecessary to decide this question because (as discussed below), while the two states’ 

laws are different, they do not result in a different outcome here. Baldwin v. Taishang 

Gypsum Co. Ltd. (In re Chinese-Manufactured Drywall Prods. Liab. Litig.), 742 F.3d 576, 586 

(5th Cir. 2014) (explaining that a “false conflict” occurs when the application of the laws of 

either state in question “would produce the same decision in the lawsuit” (citation omitted)).

legal question determined solely by reference to the contract’s terms.”). 

California has a permissive approach to the use of extrinsic evidence in 

disputes over meaning. See Spinks v. Equity Residential Briarwood 

Apartments, 90 Cal. Rptr. 3d 453, 469 (Cal. Ct. App. 2009). The Tesoro Parties 

thus argue that the district court should have followed the intent of the 

parties—(purportedly) that the owner of the refinery, whichever entity it was, 

was covered under the policy—rather than the actual words of the policy.

The district court disagreed, citing Am. Home Ins. Co. v. Travelers 

Indem. Co., 175 Cal. Rptr. 826 (Cal. Ct. App. 1981). American Home Insurance 

Company (“American Home”) wrote a property insurance policy for Toyota 

Motor Company, Toyota Motor Sales (“Sales”), and Toyota Motor Distributors 

(“Distributors”) (the latter two were wholly-owned subsidiaries of the parent 

auto manufacturer). Id. at 827. Travelers insured Davis, a “California 

corporation which maintained and prepared Toyota automobiles for 

distribution . . . .” Id. at 828. Davis and Distributors contracted to have Davis 

process certain automobiles on Distributors’ behalf. Id. Under the contract, 

Davis was supposed to maintain liability coverage for Distributors. Id.

However, the policy it procured contained a critical error: the insured premises 

were described as those leased “to the named insured.” Id. But, while Davis 

occupied the premises, Sales was the actual lessee. Id. 

A fire on the premises resulted in substantial litigation targeted at Sales. 

Id. at 829. Travelers refused to defend Sales, because Sales was not the named 

insured on the policy. Id. American Home, Sales’s general insurer, brought 

suit as Sales’s subrogee against Travelers. Id. The court determined that in 

order to have standing to sue, American Home had to demonstrate that Sales 

was an intended third-party beneficiary of the policy. Id. at 831. The court 

held that Sales was not an intended third-party beneficiary, because nothing 

in the contract evinced any express intent to benefit third parties. Id. at 834–

No. 15-50953

35. Under California law, the court said, “a policy of indemnity insurance will 

not inure to a third party’s benefit unless the contract makes such an obligation 

express, and any doubt should be construed against such intent.” Id. at 834. 

There was nothing in the contract’s language to show that Sales was intended 

to benefit from the contract, so Sales could not pursue reformation. Id. at 835.

The district court stated that the instant case was materially 

indistinguishable, and thus cited American Home Insurance for the proposition 

that, because the instant policy’s language does not evince any intent to benefit 

a third party (Tesoro Refining or otherwise), Tesoro Refining cannot assert 

third-party beneficiary status. We agree and affirm the district court’s 

summary judgment on the breach of contract claim premised upon a thirdparty beneficiary argument.

B. Reformation

The district court granted summary judgment on the Tesoro Parties’ 

reformation claim on limitations. The parties agree that Texas law governs 

this issue. Texas applies a four-year statute of limitations to reformation 

claims. Harbor Ins. Co. v. Urban Const. Co., 990 F.2d 195, 200 (5th Cir. 1993); 

TEX. CIV. PRAC. & REM. CODE § 16.051. The Tesoro Parties argue that 

limitations did not begin to run until they discovered the alleged mistake4 in 

the policy.

It has long been the law in Texas that receipt of a policy containing a 

mistake does not bar a later claim for reformation if the insured offers proof 

 

4 The identification of the precise “mistake” in the policy has been something of a 

moving target. The Tesoro Parties have at times argued that the identity of the named 

insured is the “mistake” but have conceded that Tesoro corporate practice is to list the parent 

as the named insured. The Tesoro Parties further conceded that Tesoro Corporation gains 

some benefit from the policy such as if it is held liable for environmental liabilities under a 

veil-piercing, respondeat superior, or similar theory. At oral argument, counsel for the Tesoro 

Parties explained that the “mistake” is the Tesoro Parties’ belief that Tesoro Refining was 

also covered under the policy. Both “mistakes” are obvious from the face of the policy.

“that when he received it he put it away without examination, or that he relied 

upon the knowledge of the insurer and supposed he had correctly drawn it.’” 

Fireman’s Fund Indem. Co. v. Boyle Gen. Tire Co., 392 S.W.2d 352, 355 (Tex. 

1965) (quoting Del. Ins. Co. v. Hill, 127 S.W. 283, 286–87 (Tex. Civ. App.—El 

Paso 1910, writ denied); Colonial Sav. Ass’n v. Taylor, 544 S.W.2d 116, 119

(Tex. 1976). Taylor and Boyle both address the merits of an insured’s claim for 

reformation and hold that receipt of a policy without protest is not an absolute 

bar to a reformation claim. 544 S.W.2d at 118–19; 392 S.W.2d at 354–55. In

other words, an insured is not deemed to have accepted the terms of a policy 

simply by receiving it without argument. 

This merits inquiry is distinct from the statute of limitations inquiry: 

whether the four year statute of limitations runs from the time the injury 

occurred—according to the well-settled “legal injury rule,” Murphy v. 

Campbell, 964 S.W.2d 265, 270 (Tex. 1997) —or whether, through application 

of the discovery rule, it runs from the date “the plaintiff knows or, by exercising 

reasonable diligence, should know of the facts giving rise to the claim.” Priester 

v. JP Morgan Chase Bank, N.A., 708 F.3d 667, 675 (5th Cir. 2013) (quoting 

Wagner & Brown, Ltd. v. Horwood, 58 S.W.3d 732, 734 (Tex. 2001)). Early 

cases suggested that the discovery rule applies to toll accrual of the cause of 

action for reformation. See Harbor Ins. Co., 990 F.2d at 200 (concluding that

the discovery rule did not apply because the insured had actual knowledge of 

his claim).

On the merits, the Tesoro Parties argue that they relied upon the 

“specialized knowledge” of Chartis. To benefit from the “reliance on 

knowledge” prong of the Taylor/Boyle line of cases, they must argue that they 

relied upon Chartis to determine that the correct owner of the refinery was a 

separate entity other than the named insured (Tesoro Corporation) Chartis 

was told to list. This argument makes little sense, as Chartis was hardly in a 

 Case: 15-50953 Document: 00513720174 Page: 8 Date Filed: 10/17/2016
No. 15-50953

9

superior position to know which entity purchased the refinery, i.e., which 

entity was likely to be most directly liable for any environmental problems. 

The Tesoro Parties have not directed this court to any evidence that they 

relied on Chartis to know that Tesoro Refining actually owned the refinery in 

question and to therefore draft the policy to include Tesoro Refining as an 

additional insured (i.e., a policy that covered both Tesoro Corporation and a 

separate entity, Tesoro Refining). Pressed at oral argument to identify any 

such evidence, counsel for the Tesoro Parties failed to direct the court to any 

record evidence that could support the conclusion that they relied on Chartis 

to include the correct name in the insurance policy. Thus, even if there is 

evidence buried somewhere in the various transmissions from 2002 that 

mentioned “Tesoro Refining,” there is no basis for the Tesoro Parties to argue 

that they were relying upon Chartis to ferret out that fact. See Willis v. Cleco 

Corp., 749 F.3d 314, 317 (5th Cir. 2014) (“Rule 56 does not impose upon the 

district court or the court of appeals a duty to sift through the record in search 

of evidence to support a party’s opposition to summary judgment.” (quoting 

Ragas v. Tenn. Gas Pipeline Co., 136 F.3d 455, 458 (5th Cir. 1998))).

We conclude that the Tesoro Parties did not raised a genuine issue of 

material fact issue as to the “reliance on knowledge” prong. They also point to 

no evidence of the “put it away without examination” prong. Thus, their 

argument fails on the merits.

However, even if we assume arguendo that their claim is not barred on 

the merits for the Tesoro Parties’ failure to question the policy when they 

received it, the claim was nonetheless filed too late. The Tesoro Parties sued 

for reformation many more than four years after the 2002 “mistake” was made. 

Thus, the parties argue over the application of the discovery rule here. The 

Tesoro Parties rely upon decades-old caselaw to support their arguments about 

the discovery rule. This reliance is unwarranted in light of developments in

Texas law regarding the discovery rule’s application that began in 1996. The 

Texas Supreme Court’s holdings in Comput. Assocs. Int’l, Inc. v. Altai, Inc., 918 

S.W.2d 453, 456 (Tex. 1996),5 and S.V. v. R.V., 933 S.W.2d 1, 6–7 (Tex. 1996), 

explained that the discovery rule applies only where “the nature of the injury 

[is] inherently undiscoverable and . . . the injury itself [is] objectively 

verifiable. . . . [A]pplicability of the discovery rule is determined categorically.” 

HECI Expl. Co. v. Neel, 982 S.W.2d 881, 886 (Tex. 1998) (citing Altai, 918 

S.W.2d at 456). 

The Tesoro Parties were unable to point to any basis for concluding that 

the injury in this case—the alleged mistake over which entity was covered—is 

“inherently undiscoverable.” Indeed, the mistake is evident from the face of 

the document. Texas cases since 1996 have determined the discovery rule does 

not apply to delay the accrual of the cause of action in such situations.6 

Accordingly, the Tesoro Parties’ reformation claim is time-barred.

AFFIRMED.

 

5 Altai addressed misappropriation of trade secrets. The Texas legislature later 

added a specific discovery rule for misappropriation of trade secrets, but it did nothing to 

alter the general rule (since followed in many different cases) announced in Altai for claims 

without a statutory discovery rule. TEX. CIV. PRAC. & REM. CODE §16.010(a).

6 See, e.g., Cosgrove v. Cade, 468 S.W.3d 32, 36–37 (Tex. 2015) (holding that the 

discovery rule does not apply to a reformation claim based upon plainly obvious and material 

omissions in an unambiguous deed, because such mistakes are not inherently 

undiscoverable); Via Net v. TIG Ins. Co., 211 S.W.3d 310, 313–15 (Tex. 2006) (concluding that 

the discovery rule was inapplicable to a breach of contract claim premised on the failure by a 

vendor to add the plaintiff as an additional insured on the vendor’s policy); see also Hunton 

v. Guardian Life Ins. Co. of Am., 243 F. Supp. 2d 686, 698–99 (S.D. Tex. 2001) (“Plaintiffs do 

not raise a genuine issue of fact as to whether Guardian’s alleged misrepresentations are 

inherently undiscoverable.”), aff’d, No. 01-21294, 2003 WL 21418107, at *1 (5th Cir. 2003) 

(unpublished) (concluding that discovery rule was not available in a case involving insurance 

because the alleged wrongdoing was not “otherwise undiscoverable”).
