Pilkington North America, Inc. v. Travelers Casualty & Surety Co.

{¶ 1} Pursuant to S.Ct.Prac.R. XVIII(6), we accepted three questions of state law certified by the United States District Court for the Northern District of Ohio, Western Division:

{¶ 2} 1. “Whether the demand by Pilkington North America for defense and indemnification, as asserted in this case, constitutes a chose in action, as that term is defined under Ohio law?”

{¶ 3} 2. “Whether the policies’ ‘anti-assignment’ clauses bar acquisition by Pilkington North America of such chose in action?”

{¶ 4} 3. “Whether by operation of law insurance benefits for transferred liabilities were conveyed, along with those liabilities, so that Pilkington North America may, notwithstanding the anti-assignment clauses, pursue insurance under the original LOF Glass’s policies for the environmental liabilities at issue here, which arise out of the original LOF Glass’s operations.” 105 Ohio St.3d 1514, 2005-Ohio-1880, 826 N.E.2d 313.

{¶ 5} We answer the first question as follows: A chose in action arises under an occurrence-based insurance policy at the time the loss occurred.

{¶ 6} As to the second question, we answer that such a chose in action is transferable despite the existence of an anti-assignment provision contained in the policy as to the duty to indemnify. We are unable to answer definitively whether such a chose in action is transferable as to the duty to defend.

{¶ 7} As to the third question, we answer that when a covered occurrence under an insurance policy occurs before liability is transferred to a successor corporation, coverage does not arise by operation of law when the liability was assumed by contract.

Facts and Procedural History

{¶ 8} The district court provides the following statement of facts, upon which we rely. The underlying suit is by a glass manufacturer (petitioner, Pilkington North America, Inc.), against various insurance companies that issued liability policies to Libbey-Owens-Ford Glass Company (“LOF Glass”) of Toledo. Pilkington purchased LOF Glass’s glass-manufacturing business in 1986. Pilkington has subsequently become the target of environmental claims arising from LOF Glass’s manufacturing operations.

*484(¶ 9} Pilkington filed suit against the insurers, claiming that under the policies issued to LOF Glass, the defendants owe Pilkington duties of defense and indemnity for the underlying environmental losses and actions. It is undisputed that the defendant insurance companies issued liability policies to LOF Glass.

A. Corporate History

{¶ 10} The underlying controversy involves the effect of the corporate history of LOF Glass on the insurers’ responsibilities in this case.

{¶ 11} In 1968, LOF Glass changed its name to Libbey-Owens-Ford Company to reflect its expansion into other activities not related to glass. In February 1986, Libbey-Owens-Ford Company, through a transfer and assumption agreement, placed the assets and liabilities of its glass-manufacturing division into a new, wholly owned corporate subsidiary, LOF Glass, Inc. Then in March 1986, Libbey-Owens-Ford Company entered into a share-exchange agreement with Pilkington Brothers P.L.C, a British glass manufacturer, and one of its subsidiaries, Pilkington Holdings, Inc. As a result, shares of the newly formed LOF Glass, Inc. became owned by these Pilkington entities.

{¶ 12} LOF Glass, Inc. manufactured glass under the name of Libbey-OwensFord Company from 1986 until July 2000, when it was renamed Pilkington North , America. The glass operations are ongoing.

{¶ 13} Libbey-Owens-Ford Company, after selling the glass-manufacturing operations in 1986, remained in other lines of business and has since undergone several name changes. It has been known as Trinova Corporation and most recently as Aeroquip-Vickers, Inc. It is now a wholly owned subsidiary of the Eaton Corporation. There has been no connection to the glass business since 1986.

{¶ 14} Through the 1986 transfer and assumption agreement, Pilkington has obtained both the glass business and the environmental liabilities arising from the business, including those liabilities arising from conduct by the original LOF Glass.

B. Insurance Policy Issues

{¶ 15} All parties agree that the insurance policies under which Pilkington is seeking coverage were not transferred to Pilkington and that Aeroquip-Vickers, Inc. is the current owner of these policies. As previously stated, the only present issue is Pilkington’s claims to defense and indemnification for environmental liabilities arising from the glass operations of the original LOF Glass.

{¶ 16} Pilkington argues that such coverage arises under two theories of law. It first argues that it acquired a chose in action with regard to the losses as a result of the 1986 transfer and assumption agreement. Second, it contends that *485when it purchased the glass business of the original LOF Glass, the rights to defense and indemnity under the policies followed by operation of law for environmental liabilities arising from the prior operation of that business.

{¶ 17} The respondent insurers contend that the 1986 transfer and assumption agreement transferred no interest under the policy to Pilkington because of anti-assignment clauses in the policies in question. They also generally dispute the legal contention that coverage follows a successor legal entity as a matter of law.

Analysis as to Question One

{¶ 18} The first question certified to us is whether Pilkington’s demand for defense and indemnification constitutes a “chose in action” under Ohio law.1

{¶ 19} Generally speaking, a “chose in action” is a “proprietary right in personam, such as a debt owed by another person, a share in a joint-stock company, or a claim for damages in tort.” Black’s Law Dictionary (8th Ed.2004) 258. The term can also be defined as “[t]he right to bring an action to recover a debt, money, or thing.” Id.

{¶ 20} This court has recognized that the phrase applies to the right to bring an action in tort and in contract. In Cincinnati v. Hafer (1892), 49 Ohio St. 60, 65, 30 N.E. 197, we stated: “[W]hile * * * a ‘chose in action’ is ordinarily understood [to be] a right of action for money arising under contract, the term is undoubtedly of much broader significance, and includes the right to recover pecuniary damages for a wrong inflicted either upon the person or property. It embraces demands arising out of a tort, as well as causes of action originating in the breach of a contract.”

{¶ 21} This court has never addressed the question of when a chose in action becomes an enforceable right. In the insurance context, the Sixth District Court of Appeals most recently addressed the issue in In re Estate of Ray, 6th Dist. No. WD-02-049, 2003-Ohio-2001, 2003 WL 1904412. In Ray, the court characterized a decedent’s claim against his insurer for insurance proceeds as a “chose in action” that arose when the damage occurred and that was still enforceable after the decedent’s death. The Sixth District further noted that “[a] chose in action is personalty which, unlike real property, passes on death to the holder’s executor.” Id. at ¶ 13 (citing In re Wreede (1958), 106 Ohio App. 324, 331-332, 7 O.O.2d 75, 154 N.E.2d 756). Accordingly, the Sixth District held that a casualty insurance claim arising from damage to the decedent’s real estate was a chose in action that arises when the covered loss occurs.

*486{¶ 22} The insurers in this ease contend that the analysis of the California Supreme Court in Henkel Corp. v. Hartford Acc. & Indemn. Co. (2003), 29 Cal.4th 934, 129 Cal.Rptr.2d 828, 62 P.3d 69, should apply. In Henkel, the court, applying California precedent under circumstances nearly identical to those present in the instant matter, determined that no chose in action existed at the time of transfer because the claims for defense and indemnity “had not been reduced to a sum of money due or to become due under the policy” and because the insurers “had not breached any duty to defend or indemnify” the named insured, which in this case is the original LOF Glass. Id.

{¶ 23} We have “long held that an insurance policy is a contract between the insurer and the insured.” (Emphasis sic.) Ohayon v. Safeco Ins. Co. of Illinois (2001), 91 Ohio St.3d 474, 478, 747 N.E.2d 206. In fact, the “long-standing principle” has been that “the relationship between the insurer and the insured is purely contractual in nature.” Nationwide Mut. Ins. Co. v. Marsh (1984), 15 Ohio St.3d 107, 109, 15 OBR 261, 472 N.E.2d 1061.

{¶ 24} The insurance policies in the instant case are “occurrence” policies, i.e., they provide coverage for claims resulting from injury or damage that is based upon an occurrence during the policy period, regardless of when the claim is made. Mominee v. Scherbarth (1986), 28 Ohio St.3d 270, 299, 28 OBR 346, 503 N.E.2d 717, fn. 24; Goodyear Tire & Rubber Co. v. Aetna Cas. & Sur. Co., 95 Ohio St.3d 512, 2002-Ohio-2842, 769 N.E.2d 835.

{¶ 25} The distinction between Ray and Henkel is that under Ray, the chose arises at the time of the loss, whereas in Henkel, the chose arises when the claim has been reduced to a sum of money owed. Our precedent has consistently recognized that the insurer’s coverage obligation in an occurrence policy arises at the time of the occurrence. Goodyear Tire, supra.

{¶ 26} Indeed, the United States Supreme Court applied the same principles to a chose in action in Cent. Tablet Mfg. Co. v. United States (1974), 417 U.S. 673, 685, 94 S.Ct. 2516, 41 L.Ed.2d 398:

{¶ 27} “With a fire loss, the obligation to pay arises upon the fire. Unlike an executory contract to sell, the casualty cannot be rescinded. Details, including even the basic question of liability, may be contested, but the fundamental contractual obligation that precipitates the transformation from tangible property into a chose in action consisting of a claim for insurance proceeds is fixed by the fire.” (Footnote omitted.)

{¶ 28} We adopt the same principle and hold that a chose in action arises under an occurrence-based insurance policy at the time of the covered loss. The distinction created in Henkel does not align with the obligations recognized in Ohio that the insured’s right to recover arises automatically at the time of loss. *487The lack of a specifically defined amount of recovery is not fatal to the determination that a chose exists.

Analysis as to Question Two

{¶ 29} The recognition of a chose in action in the present case does not by itself mean that Pilkington is entitled to coverage under these insurance policies. A chose in action is merely a term (albeit a somewhat vague one) for the right established at the time of the loss. See 9 Corbin on Contracts (1979) 369, Section 859 (discussing why the author refuses to use the phrase “chose in action” “wherever clear analysis is necessary,” as the phrase simply means a right against another person). The right still must have been properly transferred, and the claim must not be barred under any of the terms of the insurance policies issued to the original LOF Glass.

{¶ 30} We now address the second certified question: Whether the anti-assignment provisions in the insurance policies apply. All of the policies contain language prohibiting the assignment of any interest under the policy without the insurers’ consent.

{¶ 31} The insurers contend that this prohibition contractually eliminates any possibility of a chose in action being passed to Pilkington. On its face, this would appear to be a correct statement of the law in Ohio. As discussed above, an insurance policy is a contract between an insured and the insurer. Ohayon, 91 Ohio St.3d at 478, 747 N.E.2d 206. We should not disturb the plain language of such a contract when the intent of the parties is evident. Hybud Equip. Corp. v. Sphere Drake Ins. Co., Ltd. (1992), 64 Ohio St.3d 657, 665, 597 N.E.2d 1096.

{¶ 32} The policies proscribe an assignment of an “interest” in the policy without the insurers’ consent.2 Pilkington contends that the anti-assignment provisions do not apply to assignments after the loss has already occurred. The insurers contend that as an express contractual prohibition, the anti-assignment provisions should preclude any obligation under the policy.

{¶ 33} Pilkington is seeking to invoke two duties contained in each of the policies: the duty of indemnification and the duty to defend. Each duty is separate and distinct under a liability policy. 14 Russ & Segalla, Couch on Insurance (3d Ed.2005), Section 200:3. The duty to defend is based on the allegations presented. Sharonville v. Am. Emps. Ins. Co., 109 Ohio St.3d 186, 2006-Ohio-2180, 846 N.E.2d 833, paragraph one of the syllabus. The duty to indemnify arises from the conclusive facts and resulting judgment. 16 Couch on Insurance, Section 227:27.

*488{¶ 34} Under an occurrence policy, an insurer is obligated to defend any claim arising out of wrongful conduct occurring during the coverage period. Mominee, 28 Ohio St.3d at 299, 28 OBR 346, 503 N.E.2d 717, fn. 24; 1 Leitner, Simpson and Bjorkman, Law and Practice of Insurance Coverage Litigation (2000) 4-13, Section 4.5. The duty to defend can be the most important coverage of a commercial general liability policy and comprises an increasingly significant part of the insurer’s exposure. Hagglund, Weimer, Whitman & Hillestad, CGL Policy Handbook (2001), Sections 13.04 and 13.05; see, also, Gen. Acc. Ins. Co. v. Ins. Co. of N. Am. (1989), 44 Ohio St.3d 17, 21-22, 540 N.E.2d 266 (holding that the duty to defend represents a “substantial right” to both the insurer and the insured). In situations involving complex litigation, the cost of defense can often exceed the cost of indemnity. Rhodes, The Law of Commercial Insurance (1996), Section 1.3.2; Sherwood v. Hartford Acc. & Indemn. Co. (1997), 347 Md. 32, 43, 698 A.2d 1078 (“Not infrequently, that expense [for defense] may approximate or even exceed the amount of any judgment rendered in the action”). The duty to defend gives the insurer the right to control the conduct of the litigation in order to safeguard its interests. 1 Leitner et al., Law and Practice of Insurance Coverage Litigation, Section 4.6.

{¶ 35} The duty of defense is much broader than the duty of indemnification and can be invoked even though no liability is ultimately established. 14 Couch, Section 200:3. In Motorists Mut. Ins. Co. v. Trainor (1973), 33 Ohio St.2d 41, 62 O.O.2d 402, 294 N.E.2d 874, this court held that under a liability insurance policy, it is the scope of the allegations against the insured that determines whether an insurance company has a duty to defend the insured. Id. at paragraph two of the syllabus. We held that “where the complaint brings the action within the coverage of the policy the insurer is required to make defense, regardless of the ultimate outcome of the action or its liability to the insured.” Id. The Motorists holding was expanded in Willoughby Hills v. Cincinnati Ins. Co. (1984), 9 Ohio St.3d 177, 179, 9 OBR 463, 459 N.E.2d 555, in which we stated that “the duty to defend need not arise solely from the allegations in the complaint but may arise at a point subsequent to the filing of the complaint.”

{¶ 36} It is long-standing tradition in the common law that all contract rights may be assigned except under three conditions. 3 Restatement of the Law 2d, Contracts (1981), Section 317(2). First, if there is clear contractual language prohibiting assignment, an assignment will not be enforced. Id., Section 317(2)(c); 29 Lord, Williston on Contracts (4th Ed.2003), Section 74:10; Hybud Equip. Corp., 64 Ohio St.3d at 665, 597 N.E.2d 1096 (holding that contracts will be enforced according to their terms); Mettler-Toledo, Inc. v. Republic Powdered Metals, Inc. (May 29, 1996), 9th Dist. No. 2500-M, 1996 WL 285368 (holding that assignment of a warranty contrary to contractual prohibitions was void). Second, an assignment must not materially change the duty of the obligor, materially *489increase the insurer’s burden or risk under the contract, materially impair the insurer’s chance of securing a return on performance, or materially reduce the contract’s value. 3 Restatement 2d, Contracts, Section 317(2)(a); 29 Williston on Contracts, Section 74:10. See, also, Kitt v. Home Indemn. Co. (1950), 153 Ohio St. 505, 509, 41 O.O. 511, 92 N.E.2d 685 (holding that an insurer may not avoid liability when a change in partners of an insured partnership did not increase the underlying risk); Schofield v. Benton (Aug. 20, 1992), 10th Dist. No. 92AP-161, 1992 WL 208924 (adopting the Restatement language). Third, the assignment will not be valid if it is forbidden by statute or by public policy. 3 Restatement of Contracts, Section 317(2)(b); Robbins v. Hennessey (1912), 86 Ohio St. 181, 99 N.E. 319 (discussing statutory prohibition of assignment of a contract for payment of funeral expenses).

{¶ 37} In the insurance policies at issue, there is a contractual provision prohibiting the assignment of any interest under the policy. The anti-assignment provision has an important role in an insurance policy, as noted by the Ninth Circuit in N. Ins. Co. of New York v. Allied Mut. Ins. Co. (C.A.9, 1992), 955 F.2d 1353:

{¶ 38} “Risk characteristics of the insured determine whether the insurer will provide coverage, and at what rate. An assignment could alter drastically the insurer’s exposure depending on the nature of the new insured. ‘No assignment’ clauses protect against any such unforeseen increase in risk.” Id. at 1358.

{¶ 39} Any assignment of the rights after the losses would be, on its face, in direct contravention of this provision. It would seem that the analysis should end at this point under the plain-language approach of Hybud Equip. Corp., 64 Ohio St.3d at 665, 597 N.E.2d 1096.

{¶ 40} Insurance contracts receive unique treatment post-loss, however. Insurance policies are generally construed such that assignment of an interest is valid after the occurrence of the loss insured against, and the assignment is then regarded as a transfer of the chose in action, even in the face of an anti-assignment provision. 2 Couch, Sections 34:2 and 34:25; 17 Williston on Contracts, Section 49:126; St. Paul Fire & Marine Ins. Co. v. Allstate Ins. Co. (1975), 25 Ariz.App. 309, 311, 543 P.2d 147; Fiorentino v. Lightning Rod Mut. Ins. Co. (1996), 114 Ohio App.3d 188, 192, 682 N.E.2d 1099 (holding that an insured under a commercial general liability policy may assign its claim under the policy to the injured party without contravening the anti-assignment provision).

{¶ 41} Only a few cases addressing the issue have involved an assignment of rights under a commercial general liability policy. See Fiorentino, supra. The issue of permitting assignment after loss in avoidance of the anti-assignment clause is an easier concept when dealing with life insurance or casualty insurance. The insured loss has already occurred, is clearly defined, and the insurer’s *490liability is fixed and established. Contrast this with a loss under a commercial general liability policy, especially under the facts of the instant case, where the loss may be over a period of indeterminate length and of an indeterminate magnitude.

{¶ 42} Much of the case law involving an anti-assignment clause in a commercial general liability policy is not on point. Almost all of these cases involve the active assignment of rights from the insured to a third party, usually the injured party. Pub. Util. Dist. No. 1 of Klickitat Cty. v. Internatl. Ins. Co. (1994), 124 Wash.2d 789, 881 P.2d 1020; Elat, Inc. v. Aetna Cas. & Sur. Co. (1995), 280 NJ.Super. 62, 66, 654 A.2d 503. Few cases involve the transfer of a chose in action to a successor corporate entity solely by virtue of the succession. Most involve some form of de facto merger or other circumstance in which the original corporation is no longer in existence. Gopher Oil Co. v. Am. Hardware Mut. Ins. Co. (Minn.App.1999), 588 N.W.2d 756 (purchase by successor that subsumed predecessor); Westoil Terminals Co. v. Harbor Ins. Co. (1999), 73 Cal.App.4th 634, 86 Cal.Rptr.2d 636 (de facto merger).

{¶ 43} As mentioned above, the commercial general liability policies Pilkington is seeking coverage under contain two contractual obligations: the duty to indemnify and the duty to defend. The duty to indemnify implicates both property damage and bodily injury. The losses are fixed at the time of the occurrence. We see no reason to deviate from the standard rule on this issue, and thus we hold that the chose in action as to the duty to indemnify is unaffected by the anti-assignment provision when the covered loss has already occurred.

Analysis as to Question Three

{¶ 44} Pilkington also argues that because the policies were transferred by operation of law, the anti-assignment provisions should not be enforced. There is again limited authority as to whether insurance coverage follows liability in cases involving anti-assignment clauses.

{¶ 45} The primary case cited for the proposition that insurance coverage for presale activities follows an asset purchaser by operation of law is N. Ins., 955 F.2d 1353. In N. Ins., the Ninth Circuit held that an asset purchase transferred the duty to defend from the named insured to the purchaser as a matter of law when the liability giving rise to the policy claim arose before the purchase, even when the policy contained an anti-assignment clause. Id. at 1357-1358. In N. Ins., much of the decision was driven by the fact that liability for presale activities was itself imposed by law on the purchaser. Further, although this point was not explicitly discussed, the successor entity, as the sole party liable, is the only party capable of demanding a defense under the policies in question.

*491{¶ 46} Henkel declined to extend N. Ins. to circumstances in which the liabilities are voluntarily assumed by the asset purchaser by contract instead of imposed by operation of law. 29 Cal.4th at 941, 129 Cal.Rptr.2d 828, 62 P.3d 69. It highlighted the three circumstances under which a buyer of corporate assets may be liable by operation of law for the torts of its predecessor under California law and under which insurance coverage would follow by operation of law. Id. at 941-942, 129 Cal.Rptr.2d 828, 62 P.3d 69. Because the liability for which coverage was sought was contractually conveyed to the successor, and the insurance policy had an anti-assignment provision, the Henkel court held that coverage did not follow by operation of law. Further, the court noted that any attempt to transfer coverage to a successor must fail when the original insured still exists or can be revived to demand a defense — a distinction not addressed in N. Ins. Henkel, 29 Cal.4th at 945, 129 Cal.Rptr.2d 828, 62 P.3d 69.

{¶ 47} N. Ins. relied on the fact that California and Washington apply the rule of product-line successor liability. Under this theory, “a purchaser of substantially all assets of a firm assumes, with some limitations, the obligation for product liability claims arising from the selling firm’s presale activities. Liability is transferred irrespective of any clauses to the contrary in the asset purchase agreement.” N. Ins., 955 F.2d at 1357. The rationale for transferring insurance coverage for indemnification and defense by operation of law in such an instance is sound, since an unwary purchaser may be liable for significant bodily injury or property damage occurring before the sale, solely as a result of the purchase. The result also serves to ensure that the injured party receives recompense.

{¶ 48} Ohio does not follow the California product-line successor liability theory. Ohio has adopted the general rule of successor liability, which provides that the purchaser of a corporation’s assets is not liable for the debts and obligations, including liability for tortious conduct, of the seller corporation. Flaugher v. Cone Automatic Mach. Co. (1987), 30 Ohio St.3d 60, 30 OBR 165, 507 N.E.2d 331; Cyr v. B. Offen & Co., Inc. (C.A.1, 1974), 501 F.2d 1145, 1152; 15 Fletcher, Cyclopedia of the Law of Private Corporations (1999), Section 7122. There are four exceptions to this general rule, three of which impose liability without regard to contract. A successor corporation may be held liable when:

{¶ 49} “(1) the buyer expressly or impliedly agrees to assume such liability;

{¶ 50} “(2) the transaction amounts to a defacto consolidation or merger;

{¶ 51} “(3) the buyer corporation is merely a continuation of the seller corporation; or

{¶ 52} “(4) the transaction is entered into fraudulently for the purpose of escaping liability.” Flaugher, 30 Ohio St.3d at 62, 30 OBR 165, 507 N.E.2d 331.

*492{¶ 53} Additionally, some statutes, including the Comprehensive Environmental Response, Compensation, and Liability Act (Section 9601 et seq., Title 42, U.S.Code) have been construed as imposing liability on successor corporations without regard to contract. SmithKline Beecham Corp. v. Rohm & Haas Co. (C.A.3, 1996), 89 F.3d 154, 157; Anspec Co., Inc. v. Johnson Controls, Inc. (C.A.6, 1991), 922 F.2d 1240.

{¶ 54} None of those instances in which liability is imposed without regard to contract are alleged to be present. Thus, liability is not being imposed on Pilkington by operation of law, and we do not reach the question as to whether coverage follows by operation of law in such a circumstance.

{¶ 55} Some courts have expanded N. Ins. to include successor-liability cases not based on the product-line theory. See, e.g., Glidden Co. v. Lumbermens Mut. Cas. Co., 8th Dist. No. 81782, 2004-Ohio-6922, 2004 WL 2931019, ¶ 64. See, also, B.S.B. Diversified Co., Inc. v. Am. Motorists Ins. Co. (W.D.Wash.1996), 947 F.Supp. 1476, 1481-1482; Total Waste Mgt. Corp. v. Commercial Union Ins. Co. (D.N.H.1994), 857 F.Supp. 140.

{¶ 56} There are a number of courts, in addition to Henkel, that have taken a different approach, holding that the contractual obligation defines the relationship between the parties when the liability arises as a matter of contract. Red Arrow Prods. Co., Inc. v. Employers Ins. of Wausau (App.2000), 233 Wis.2d 114, 132-134, 607 N.W.2d 294; Gen. Acc. Ins. Co. v. Alameda Cty. Super. Court (1997), 55 CaLApp. 4th 1444, 1454-1455, 64 Cal.Rptr.2d 781; Quemetco, Inc. v. Pacific Auto. Ins. Co. (1994), 24 Cal.App.4th 494, 500-503, 29 Cal.Rptr.2d 627.

{¶ 57} The courts expanding the N. Ins. holding to cases in which the underlying liability is contractually assumed and does not arise as a matter of law do so under the simple rationale that coverage should follow liability.

{¶ 58} This rationale is generally incorrect for cases in which liability is contractually assumed for the following reasons. First, as discussed, insurance is a contract between the insurer and the insured. Ohayon, 91 Ohio St.3d at 478, 747 N.E.2d 206. The parties specifically contract to control liability. Allowing indemnity to follow liability as a matter of law interferes with that control. If the parties fail to explicitly describe their rights under an insurance contract, they may have had their reasons, and requiring that coverage follow as a matter of law interferes in the contractual process.

{¶ 59} A commercial general liability policy can cover a business that maintains several plants or several different lines of business. When selling one of those plants, or one of those lines of business, a contractual agreement to assign liability but not the underlying chose in action may be designed to preserve rights under the policy for the original insured.

*493{¶ 60} Further, if coverage were to arise by operation of law and the original insured remains in operation, the limits of its coverage available under the policy may be reduced by any indemnity payments made on behalf of the additional insured. Additionally, and as discussed above, in certain cases, the insurer may be placed in the position of defending an additional insured where there was only one under the policy. The results of such complications are numerous under an “operation of law” theory that gives no consideration to whether the liabilities were assumed by contract or forced upon the successor by operation of law.

{¶ 61} We therefore hold that when a covered occurrence under an insurance policy occurs before liability is transferred to a successor corporation, coverage does not arise by operation of law when the liability was assumed by contract.

So answered.

As to Question One as answered:

As to Question Two, to the extent answered:

As to Question Three as answered:

Separate views of Moyer, C J., and O’Connor, J., as to Question Two:

{¶ 62} The duty to defend requires a different analysis. The second prohibition on assignment of contractual rights forbids assignment when there would be a material change in the duty of the obligor or a material increase of the burden or risk imposed on the obligor. Both of these possibilities are implicated in this case by the assignment of the duty of defense.

{¶ 63} The duty of defense is a more personal and individual right in the case of an assignment. There can be only one recovery for property damage or *494personal injury, but when, as here, another insured (Aeroquip-Vickers) has maintained the coverage once held by the original LOF Glass, while Pilkington is making a claim as an additional insured, there are now multiple potential parties to defend.

{¶ 64} In a commercial general liability situation, with an assignment of rights notwithstanding an anti-assignment clause, transfer of the right to demand a defense may constitute a material change in the duties of the insurer, who could be obligated to defend multiple parties. It may also constitute a material increase in the insurer’s obligations, as the cost of defense in such a circumstance would now almost certainly be higher.

{¶ 65} This was precisely the concern in Henkel:

{¶ 66} “If both assignor and assignee were to claim the right to defense, the insurer might effectively be forced to undertake the burden of defending both parties. In view of the potential for such increased burdens, it is reasonable to uphold the insurer’s contractual assignment right to accept or reject an assignment.” 29 Cal.4th at 945, 129 Cal.Rptr.2d 828, 62 P.3d 69.

{¶ 67} There are, of course, other considerations. In N. Ins. Co. of New York v. Allied Mut. Ins. Co. (C.A.9, 1992), 955 F.2d 1353, which involved the question of whether coverage followed liability by operation of law, the insurers contended that they had no duty to defend because of a substitution of one defendant for another. The Ninth Circuit disagreed, holding that it was the “nature of the risk,” rather than the characteristics of the individual defendant, that mattered. Id. at 1358.

{¶ 68} The language of the preceding paragraphs is couched in potentials and possibilities, but so, ultimately, is the business of insurance. The insurer accepts the risk of providing coverage based on the representations made by the insured. Rhodes, The Law of Commercial Insurance (1996), 383, Section III.4.1. The insurance policy, by its terms, contemplates defending only the named insured. Being obligated to defend parties other than the named insured may materially increase that risk.

{¶ 69} We note that this increased risk might not occur when the original insured corporation is no longer in existence and is incapable of being sued or of demanding a defense under the original commercial general liability policy. In such a circumstance, the insurer has incurred no increase in obligation, and the rationale for this rule falls away.

{¶ 70} We therefore believe that, after the loss has occurred, an anti-assignment clause in an insurance policy does apply to a claim for defense when the *495assignment places upon the insurer a materially changed duty or a materially increased risk.
