             4444444444444444444444444444444444444444444444444444

                                        Argued September 2, 2015


       CHIEF JUSTICE HECHT delivered the opinion of the Court.


       The insured under a standard-form commercial general liability insurance policy supplied

flanges for use in constructing refinery processing units. The flanges leaked and had to be replaced

to avoid the risk of fire or explosion. The flanges were welded to the pipes they joined and therefore

had to be cut out while the refineries were shut down. The insured claims that its liability for the

refinery owner’s replacement costs and downtime damages are covered by its CGL policy.

       The policy covers “physical injury” to property and the lost use of property that could not be

restored by replacing the flanges. Four questions certified to us by the United States Court of

Appeals for the Fifth Circuit1 raise two issues. One is whether property is physically injured merely


       1
           589 F. App’x 659, 663–664 (5th Cir. 2014) (mem. op.).
by installing a defective product into it. This is an issue over which American jurisdictions have

differed and one which we have not had occasion to consider. The other issue is whether replacing

the flanges restored the refinery property to use when some of the property was destroyed in the

process. We conclude that the policy does not cover most of the damages claimed and answer the

Circuit’s questions accordingly.

                                                     I

       U.S. Metals, Inc. sold ExxonMobil Corp. some 350 custom-made, stainless steel, weld-neck

flanges for use in constructing nonroad diesel units at its refineries in Baytown, Texas, and Baton

Rouge, Louisiana. The units remove sulfur from diesel fuel and operate under extremely high

temperatures and pressures. ExxonMobil contracted for flanges made to meet industry standards and

designed to be welded to the piping. The pipes and flanges, after they were welded together, were

covered with a special high temperature coating and insulation.

       In post-installation testing, several flanges leaked. Further investigation revealed that the

flanges did not meet industry standards, and ExxonMobil decided it was necessary to replace them

to avoid the risk of fire and explosion. For each flange, this process involved stripping the

temperature coating and insulation (which were destroyed in the process), cutting the flange out of

the pipe, removing the gaskets (which were also destroyed in the process), grinding the pipe surfaces

smooth for re-welding, replacing the flange and gaskets, welding the new flange to the pipes, and

replacing the temperature coating and insulation. The replacement process delayed operation of the

diesel units at both refineries for several weeks.



                                                     2
       ExxonMobil sued U.S. Metals for $6,345,824 as the cost of replacing the flanges and

$16,656,000 as damages for the lost use of the diesel units during the process. U.S. Metals settled

with ExxonMobil for $2.2 million and then claimed indemnification from its commercial general

liability insurer, Liberty Mutual Group, Inc., for the amount paid.

       The convoluted provisions of the standard-form CGL policy:

•      obligate Liberty Mutual to “pay those sums that [U.S. Metals] becomes legally obligated to
       pay as damages because of . . . ‘property damage’ to which this insurance applies”;

•      define “property damage” to mean “[p]hysical injury to tangible property, including all
       resulting loss of use of that property”, and “[l]oss of use of tangible property that is not
       physically injured”;

•      exclude, in subparagraph K, “‘property damage’ to ‘your product’ arising out of it or any part
       of it”;

•      exclude, in subparagraph M, “‘[p]roperty damage’ to ‘impaired property’ or property that has
       not been physically injured, arising out of . . . [a] defect, deficiency, inadequacy or dangerous
       condition in ‘your product’”;

•      define “your product” to mean “[a]ny goods or products . . . sold . . . by [U.S. Metals]”; and

•      define “impaired property” to mean:

               tangible property, other than “your product” . . . , that cannot be used or is
               less useful because:

               a.      It incorporates “your product” . . . that is known or thought to be
                       defective, deficient, inadequate or dangerous; or

               b.      You have failed to fulfill the terms of a contract or agreement;

               if such property can be restored to use by the repair, replacement, adjustment
               or removal of “your product” . . . or your fulfilling the terms of the contract
               or agreement.



                                                  3
        All damages for which U.S. Metals claims coverage arose out of its defective flanges, and

thus Exclusions K and M apply. Under Exclusion K, damages to the flanges themselves are not

covered, and U.S. Metals does not claim them. Under Exclusion M, the policy does not cover

damages to property, or for the loss of its use, if the property was not physically injured or if it was

restored to use by replacement of the flanges. The existence and extent of coverage thus depends on

whether ExxonMobil’s property was (1) physically injured or (2) restored to use by replacing the

flanges. U.S. Metals contends that ExxonMobil’s property was physically injured both by the mere

installation of the faulty flanges and also later, during the replacement process. U.S. Metals further

contends that the diesel units could not be restored to use simply by replacing the flanges because

welds, gaskets, insulation, and coating were destroyed in the process and had to be replaced as well.

        Liberty Mutual denied coverage, and U.S. Metals sued in federal district court to determine

its right to a defense and indemnity under the policy. The court granted summary judgment for

Liberty Mutual. On appeal, the Fifth Circuit certified to this Court the following four questions

inquiring about the meaning of “physical injury” and “replacement” in the CGL policy and their

application in this situation:

        1.      In the “your product” and “impaired property” exclusions, are the terms
                “physical injury” and/or “replacement” ambiguous?

        2.      If yes as to either, are the aforementioned interpretations offered by the
                insured reasonable and thus, must be applied pursuant to Texas law?




                                                   4
         3.        If the above question 1 is answered in the negative as to “physical injury,”
                   does “physical injury” occur to the third party’s product that is irreversibly
                   attached to the insured’s product at the moment of incorporation of the
                   insured’s defective product or does “physical injury” only occur to the third
                   party’s product when there is an alteration in the color, shape, or appearance
                   of the third party’s product due to the insured’s defective product that is
                   irreversibly attached?

         4.        If the above question 1 is answered in the negative as to “replacement,” does
                   “replacement” of the insured’s defective product irreversibly attached to a
                   third party’s product include the removal or destruction of the third party’s
                   product?2

         As we will explain, the parties’ dispute and the certified questions distill to two essential

inquiries. First: did the mere installation of the faulty flanges physically injure the diesel units when

the only harm at that point was the risk of leaks? Or put more generally: is property physically

injured simply by the incorporation of a faulty component with no tangible manifestation of injury?

And second: is property restored to use by replacing a faulty component when the property must be

altered, damaged, and repaired in the process? We will address these issues in turn and then answer

the certified questions.

                                                             II

         A few basic principles guide our analysis. The interpretation of an insurance policy, like other

contracts, begins with the text,3 and requires that undefined words be given their plain, ordinary, and

generally accepted meanings absent some indication of a different intent.4 An interpretation that

gives each word meaning is preferable to one that renders one surplusage.5 And a policy provision

is ambiguous only if it is subject to more than one reasonable interpretation6 and not merely because

the parties7 or other courts8 differ over its interpretation. With these basic principles in mind, we turn

to the policy provisions at issue.

         The parties dispute whether the installation of the faulty flanges physically injured the diesel

units within the meaning of the CGL policy. The policy covers “injury”, which means “[t]he

violation of another’s legal right”, or more generally, “[a]ny harm or damage.”9 But the policy does

not cover every injury; it covers only “physical injury”. “Physical” means “[o]f, relating to, or

involving material things; pertaining to real, tangible objects”.10

         A thing whose use or function is diminished by the incorporation of a faulty component can

fairly be said to be injured, even if the injury is intangible, latent, or inchoate. Here, the installation

of the leaky flanges—or at least potentially leaky, and in any event below-standard—can certainly

be said to have injured—harmed or damaged—the diesel units by increasing the risk of danger from

their operation and thus reducing their value. But if that increased risk amounted to physical injury

within the meaning of the CGL policy, then it is difficult to imagine a non-physical injury. Any

lessening of property by adding a component would be not only injury but physical injury. The

policy’s limitation of coverage to damages from physical injury necessarily implies that there can

be non-physical, non-covered injuries. Otherwise, the requirement that injury be “physical” would

be superfluous. To give “physical” its plain meaning, a covered injury must be one that is tangible.

         The meaning of “physical injury” in a standard-form CGL policy has been thoroughly

explored in two cases. The issue in both was whether a home was physically injured when the

plumbing system was installed—the incorporation theory—or not until years later when it began to

leak—the actual harm theory. In the first case, Eljer Manufacturing, Inc. v. Liberty Mutual Insurance

Co. (Eljer I), a Seventh Circuit panel, applying Illinois law, acknowledged that

       [t]he central meaning of [physical injury] as it is used in everyday English—the
       image it would conjure up in the mind of a person unschooled in the subtleties of
       insurance law—is of a harmful change in appearance, shape, composition, or some
       other physical dimension of the “injured” person or thing. If water leaks from a pipe
       and discolors a carpet or rots a beam, that is physical injury, perhaps beginning with
       the very earliest sign of rot—the initial contamination . . . . The ticking time bomb,
       in contrast, does not injure the structure in which it is placed, in the sense of altering
       the structure in a harmful, or for that matter in any, way—until it explodes.11

But the panel majority rejected this theory, reasoning instead that because the purpose of insurance

is to spread risks, and because the failure rate was sufficiently high to mark the product as defective

and induce a rational owner to replace the plumbing system before it leaked, the inclusion of the

system in a home was physical injury.12 The majority’s Erie-guess,13 though less than firm, was that

the Illinois Supreme Court would embrace the incorporation theory of physical injury for CGL policy

coverage.14

        The majority guessed wrong. Nine years later, in Travelers Insurance Co. v. Eljer

Manufacturing, Inc. (Eljer II), the Illinois Supreme Court held that incorporating a defective

component into something is not, in and of itself, “physical injury”, even though there is “intangible

damage, such as diminution in value”.15

        [W]ithout a harmful change in appearance, shape, composition, or some other
        physical dimension to the claimants’ property, the insurance coverage is not
        triggered. We believe that [Eljer I] erred when it set aside the central, plain, and
        ordinary meaning of the term physical injury . . . .16

        Our case does not have the timing issue the Eljer cases had. Some of the plumbing systems

in those cases did not leak for years after the systems were installed, whereas U.S. Metals’ flanges

leaked from the very start, in initial testing before they were even placed into service. But the salient

point to be drawn from Eljer II is that physical injury, for purposes of the same CGL policy provision

at issue here, resulted not from the installation but from the leak. Leaks from U.S. Metals’ flanges

never caused injury because ExxonMobil replaced them to avoid any risk of injury.

        We count twelve state high courts that have considered whether to adopt the incorporation

theory in interpreting “physical injury” in CGL policies. Of those, five have rejected the theory

Several other state and federal courts have rejected the incorporation theory.20

            See U.S. Fire Ins. Co. v. J.S.U.B., Inc., 979 So. 2d 871, 890 (Fla. 2007) (recognizing that the “mere inclusion
of a defective component” is not property damage); Travelers Indem. Co. of Am. v. Moore & Assocs., Inc., 216 S.W .3d
302, 309–310 (Tenn. 2007) (same); United Nat’l Ins. Co. v. Frontier Ins. Co., 99 P.3d 1153, 1158 (Nev. 2004)

the sign was negligently attached to its frame); Wyo. Sawmills, Inc. v. Transp. Ins. Co., 578 P.2d 1253, 1256 (Or. 1978)
(rejecting the insured’s argument that defective studs “became integrated into and were made a part of the building and
their subsequent warping was damage to the building whether the damage was limited to the studs or not”); see also
Taylor Morrison Servs., Inc. v. HDI-Gerling Am. Ins. Co., 746 S.E.2d 587, 591 n.10 (Ga. 2013) (quoting the decision
in J.S.U.B. approvingly but failing to reach the “property damage” issue).

         18
            Five state high courts have implicitly rejected the incorporation theory by holding that property damage
covered under a CGL does not include defective work or a defective component alone, but would include damage caused
by that defective work or component to other property. See Capstone Bldg. Corp v. Am. Motorists Ins. Co., 67 A.3d 961,
980–982 (Conn. 2013); Crossmann Cmtys. of N.C. Inc. v. Harleysville Mut. Ins. Co., 717 S.E.2d 589, 594 (S.C. 2011);

199 P.3d 376, 384 (W ash. 2008) (damage caused by the defective siding to the subsurface and interior walls, installed
not by the insured but by others, was property damage covered by the policy; thus, removal and reinstallation of the
siding to repair damage to the walls was within the scope of property damage).

         19
             Citing Eljer I, the W yoming Supreme Court noted, without further analysis, that “[i]t is well-recognized that
the installation of a defect into a building is physical injury as defined in insurance policies.” Helm v. Bd. of Cty.
Comm’rs, 989 P.2d 1273, 1276 (W yo. 1999). But Helm predates most of the contrary decisions, and the “defect”
“installed” was actually the county’s negligent inspection of a home. Id. at 1274. The Supreme Court of Montana adopted
the incorporation theory for a case involving the application of defective paint to water pipes and tanks. Swank Enters.,
Inc. v. All Purpose Servs., Ltd., 154 P.3d 52, 56 (Mont. 2007) (holding that “physical injury” for purposes of “property
damage” under a commercial general liability insurance contract refers to a physical and material alteration resulting in
a detriment). Note that the New York Court of Appeals, in applying incorporation theory in a limitations case, cited
approvingly insurance coverage cases holding that injury-in-fact occurs when a defective component is integrated into
a larger product, and that the trigger date for coverage was the date of installation of asbestos insulation. See MRI
Broadway Rental, Inc. v. U.S. Mineral Prods. Co., 704 N.E.2d 550, 553 (N.Y. 1998) (citing Sturges Mfg. Co. v. Utica
Mut. Ins. Co., 332 N.E.2d 319, 322 (N.Y. 1975) (explaining, in a case involving defective components in ski bindings,
that “[w]hen one product is integrated into a larger entity, and the component product proves defective, the harm is
considered harm to the entity to the extent that the market value of the entity is reduced in excess of the value of the
defective component”), and Md. Cas. Co. v. W. R. Grace & Co., 23 F.3d 617, 627 (2d Cir. 1993) (“holding that
installation of asbestos is an occurrence of damage-in-fact and triggers the insurance coverage in effect at that time”));
see also Hoechst Celanese Corp. v. Certain Underwriters at Lloyd’s London, 673 A.2d 164, 169 (Del. 1996) (rejecting,
as a matter of New York law, that “‘property damage’ occurs only at the time of a leak in the plumbing system, or when
the homeowner decides to replace the system”).

         20
            In an analogous case, the Eighth Circuit concluded that the incorporation of defectively welded pipe sections
into a larger piping structure was not physical injury: “there is no ‘property damage’ unless and until the incorporation
of a defective product or component results in ‘physical injury to tangible property’ in at least some part of the system.”

         We agree with most courts to have considered the matter that the best reading of the standard-

form CGL policy text is that physical injury requires tangible, manifest harm and does not result

merely upon the installation of a defective component in a product or system. Our rejection of the

incorporation theory is consistent with our other interpretations of CGL policies. We have held that

faulty workmanship can be the basis of an “occurrence”, though we noted that “faulty workmanship

that merely diminishes the value of the home without causing physical injury or loss of use does not

involve ‘property damage.’”21 We have further held that, for purposes of a duty to defend under an

occurrence-based policy period, damage due to faulty workmanship “occurs” not at the time the

damage manifests (when it is discovered or discoverable) nor when the plaintiff is exposed to the

agent that will eventually cause the damage (when it is installed, presumably).22 Rather, under a

straightforward reading of the policy, we concluded that “[o]ccurred means when damage occurred,

not when discovery occurred.”23 Since a defective product that causes damage is not an occurrence

until the damage actually happens, it would be inconsistent to now find that a defective product that

does not cause damage is nevertheless an occurrence at the time of incorporation.



F.2d 696 (9th Cir. 1991), the court concluded that the policy’s 1973 addition of “physical” meant that mere diminution
in value caused by the incorporation of the insured’s defective products was not covered property damage under the post-
1986 version of the policy. Id. at 700–701. Here in Texas, the First Court of Appeals held that there was no coverage
for costs to repair defective welds where “the welds were never ‘in an initial satisfactory state that was changed by some
external event into an unsatisfactory state’” because they were defective to begin with. N. Am. Shipbuilding, Inc. v. S.

        The result in this case has a perverse aspect to it. Had ExxonMobil been negligent or

reckless—had it not tested the flanges, or had it found the defect but decided to risk the danger of

leaks—and an explosion had resulted, U.S. Metals would not be denied coverage for the damages

to persons and property for want of physical injury. But because ExxonMobil was careful and

cautious, U.S. Metals is not entitled to indemnity for the costs of remedying the installation of the

faulty flanges. Nevertheless, we think the text of the policy is clear.

        Several associations of contractors argue as amici curiae that the construction industry needs

insurance to manage the risk that one contractor’s work on a project will damage the entire project

and other contractors, resulting in enormous repair costs and downtime.24 Two insurer groups as

amici curiae counter that it would be bad policy to allow contractors to insure against the quality of

their own work.25 This is a disagreement we cannot resolve. Our responsibility is to determine not

what coverage should be available but what the CGL policy here provided.

        We conclude that ExxonMobil’s diesel units were not physically injured merely by the

installation of U.S. Metals’ faulty flanges.

        But the units were physically injured in the process of replacing the faulty flanges. Because

the flanges were welded to pipes rather than being screwed on, the faulty flanges had to be cut out,

pipe edges resurfaced, and new flanges welded in. The original welds, coating, insulation, and

gaskets were destroyed in the process and had to be replaced. The fix necessitated injury to tangible

property, and the injury was unquestionably physical.

       Thus, the repair costs and damages for the downtime were “property damages” covered by

the policy unless Exclusion M applies. As explained above, Exclusion M denied coverage of

damages to impaired property—defined by the policy as property that could be “restored to use by

the . . . replacement” of the faulty flanges. U.S. Metals concedes that if the flanges had been screwed

onto the pipes, removal and replacement would have been a simple matter, readily restoring the

diesel units to use, and making them “impaired property”. But because the flanges were welded in,

U.S. Metals argues, restoring the diesel units to use involved much more than simply removing and

replacing the flanges alone, and therefore the diesel units were not “impaired property” and

Exclusion M does not apply.

       We disagree. The policy definition of “impaired property” does not restrict how the defective

product is to be replaced. U.S. Metals’ argument requires limiting the definition to property “restored

to use by the . . . replacement of [the flanges]” without affecting or altering the property in the

process. That limitation cannot be fairly inferred from the text itself, nor would it make sense to do

so. In U.S. Metals’ view, the diesel units could not be restored to use by replacement of the flanges,

not only because they had to be cut out and welded back in, but because of the wholly incidental

replacement of insulation and gaskets. Coverage does not depend on such minor details of the

replacement process but rather on its efficacy in restoring property to use.

       The diesel units were restored to use by replacing the flanges and were therefore impaired

property to which Exclusion M applies. Thus, their loss of use is not covered by the policy. But the

insulation and gaskets destroyed in the process were not restored to use; they were replaced. They

were therefore not impaired property to which Exclusion M applied, and the cost of replacing them

was therefore covered by the policy.26

        We come finally to the four questions certified to us by the Fifth Circuit. The first asks

whether the terms “physical injury” or “replacement” are ambiguous as incorporated into the “your

product” or “impaired property” exclusions of the CGL policy. From all we have said, the answer,

in the situation presented, is “no”. The second question is conditioned on a “yes” answer to the first,

and thus we do not answer it. The third question asks whether installation of the faulty flanges alone

physically injured the diesel units. As we have explained in Part II-A above, the answer is “no”. For

the answer to the fourth question, we refer the Circuit to Part II-B above.
