OPINION AND ORDER
This diversity suit concerns’liability insurance coverage for personal injury claims arising from exposure to asbestos. Defendant and third-party plaintiff Tread-well Corporation (“Treadwell”) installed and otherwise handled products containing asbestos between the 1940s and the 1980s, during some of which time Treadwell was covered by primary and excess liability insurance. In 1994, Treadwell and several of its liability insurers sought declaratory relief clarifying the extent to which Tread-well was entitled to indemnification for claims arising out of its asbestos-related activities (the “Asbestos Claims”). In 1997, however, Treadwell and all parties other than the United States Fire Insurance Company (“U.S.Fire”) and the Home *82 Insurance Company (“Home Insurance”) settled their disputes. Treadwell’s third-party claims against U.S. Fire and its cross-claims against Home Insurance are the only disputes remaining.
Both Treadwell and U.S. Fire now move for summary judgment pursuant to Fed. R.Civ.P. 56. By stipulation, the parties agree for the purposes of these motions that to the extent a person asserting a claim against Treadwell was injured by exposure to asbestos, he was injured at all points in time from initial exposure through the date his claim was filed or he died. (StipJ 3) 1 Thus, the parties agree that some of those making claims against Treadwell (the “Asbestos Claimants”) might have suffered injury continuously from the 1940s, when Treadwell’s asbestos-related activities began, through the 1990s, when the most recent Asbestos Claimants filed suit — a span that includes a period of more than 20 years when Treadwell did not have insurance as well as a period of 20 years in which it was insured under both primary and excess policies.
U.S. Fire provided Treadwell excess insurance from 1970 through 1972. By the terms of its policies, U.S. Fire agreed to assume coverage responsibility upon exhaustion of Treadwell’s primary insurance policies for-these years, which were issued by the American Mutual Liability Insurance Company (“AMLIC”). AMLIC is now insolvent, however, so Treadwell assumed in the 1997 settlement some of the liability that might otherwise have been borne by AMLIC. As discussed below, the principal question before the court, therefore, is whether this liability assumed by Treadwell can be allocated entirely to the AMLIC policy years, which would exhaust the AMLIC policies and trigger U.S. Fire’s coverage. Resolving this question, however, requires consideration of several subsidiary questions, including: (1) whether this court has authority to order allocation of Treadwell’s liability for the Asbestos Claims among all potentially liable parties; (2) whether Treadwell itself must assume some share of the liability for the years in which it was uninsured; and (3) what effects, if any, Treadwell’s settlements with its other insurers have on U.S. Fire’s liability. Whether, and to what extent, U.S. Fire is obligated to defend or indemnify Treadwell for any of the Asbestos Claims turns on the answers to these questions.
For the reasons stated below, I conclude that the primary insurance polices underlying U.S. Fire’s policies likely are not yet exhausted and, therefore, that U.S. Fire has no present obligation to defend or indemnify Treadwell. Accordingly, U.S. Fire’s motion for summary judgment will be granted, and Treadwell’s denied, subject to confirmation of that likelihood through examination of the individual Asbestos Claims in conformity with the rulings below.
I.
The following relevant facts are undisputed, unless otherwise noted. Treadwell, a privately held corporation organized under Delaware law with its principal place of business in Connecticut, manufactures, repairs and maintains oxygen generators used on nuclear submarines. (Compl. ¶ 4; 9/16/98 Johnson Aff. ¶ 4) 2 From sometime in the 1940s to sometime in the 1980s, however, Treadwell served also as a contractor or subcontractor, primarily at utility powerhouse sites in the New York metropolitan area. (9/16/98 Johnson Aff. ¶ 4) As part of this work, Treadwell installed and otherwise handled material containing asbestos. (Id; see Stip. ¶ 1) At no point did Treadwell manufacture, sell or distrib *83 ute asbestos or asbestos-containing products. (Stip^ 1)
In the late 1980s, Treadwell began to be named as a defendant in lawsuits alleging bodily injury arising from exposure to asbestos. (Id.) A large number of these Asbestos Claims have been settled, dismissed or otherwise disposed of, but as of August 31, 1998, there were more than 6000 such cases still pending against Treadwell, predominantly in New York state court. (9/16/98 Johnson Aff. ¶ 15;. see Antonucci Aff. ¶ 2; Stip. ¶ 1) 3 Nearly all the plaintiffs in these cases allege exposure to asbestos prior to January 1, 1970, the effective date of U.S. Fire’s excess insurance policies. (Antonucci Aff. ¶ 4. But see U.S. Fire Local Rule 56.1 Statement ¶ 9 (noting that there “were at least 39 Powerhouse Claimants who did not begin working at the powerhouses until 1970 or later and so could not have been first exposed to asbestos at the powerhouses prior to 1970”))
A. Treadwell’s Insurance Coverage
Treadwell was uninsured prior to 1967. 4 (Reilly Aff. ¶ 46) However, from January 1, 1967 until July 1, 1986, a period Treadwell refers to as “the Coverage Block,” the company was insured under several primary comprehensive general liability (“CGL”) policies: From 1967 through 1969, and again from 1973 through June 20, 1983, Treadwell was' insured under policies issued by CIGNA Property and Casualty Insurance Company, its subsidiaries and affiliates (“CIGNA”); from 1970 through 1972, the company was insured by AMLIC; and from June 20, 1983 through July 1, 1986, Treadwell was insured by the Travelers Insurance Companies (“Travelers”). (Treadwell Local Rule 56.1 Statement ¶ 33) For all of this period, Treadwell was insured also under excess CGL policies, triggered by exhaustion of the underlying primary insurance: From 1967 through 1969, and again from 1973 through June 20, 1985, Treadwell was insured under excess CGL policies issued by CIGNA; and from 1970 through 1972, Treadwell was insured under excess CGL policies issued by U.S. Fire. 5 (Id. ¶33) Thus, Treadwell’s insurance coverage for the years relevant to these motions was as follows:
*84 [[Image here]]
In addition to these insurance policies, which were purchased directly by Tread-well and which provided comprehensive coverage within their respective periods, Treadwell was a named insured on several policies purchased by utilities covering work done at their sites. The United States Fidelity & Guaranty Co. (“USF & G”) and the Commercial Union Insurance Company (“CU”) each issued primary insurance policies naming Treadwell as an insured. (9/16/98 Johnson Aff. ¶ 8(b)) Exhaustion of the USF & G policy triggered an excess policy issued by Home Insurance, which named Treadwell also as an insured. (Id.)
B. The U.S. Fire Policies
As noted, Treadwell purchased primary liability insurance from AMLIC for the years 1970, 1971 and 1972. For each of these three years, AMLIC’s coverage was limited to $100,000 per person, $300,000 per occurrence and $300,000 in “products aggregate” for bodily injuries. (Stip. ¶ 7 & Ex. C) To insure against liability above these limits, Treadwell purchased two excess umbrella policies from U.S. Fire, which together covered the same period. (Id. ¶¶ 4-6)
The U.S. Fire policies, like Treadwell’s other insurance policies, are CGL policies, standard-form industry contracts dating to the 1960s.
See American Home Prods. Corp. v. Liberty Mut. Ins. Co.,
The policies define “ultimate net loss” as the total of the following sums “with respect to each occurrence”:
(1) All sums which the insured, or any company as his insurer, or both, become legally obligated to pay as damages, whether by reason of adjudication or settlement, because of personal injury ... to which this policy applies, and
(2) All expenses incurred by the insured in the investigation, negotiation, settlement and defense of any claim or suit seeking such damages....
(Id. at 2) In turn, the policies define “occurrence” as “a continuous or repeated exposure to conditions which unexpectedly and unintentionally causes injury to persons or tangible property during the policy period. Ml damages arising out of such exposure to substantially the same general *85 conditions shall be considered as arising out of one occurrence.” (Id. at 5)
Finally, to the extent relevant here, the U.S. Fire policies both contain “other insurance” clauses. Those clauses read in relevant part: “If other collectible insurance with any other insurer is available to the insured covering a loss also covered hereunder ... the insurance hereunder shall be in excess of, and not contribute with, such other insurance.” (Id. at 3)
C. Early Negotiations, the Interim Agreement and the Commencement of Litigation
Soon after the Asbestos Claims were initiated, Treadwell provided notice and sought reimbursement for defense and indemnity against its principal primary insurers — CIGNA, Travelers and AMLIC. (9/16/98 Johnson Aff. ¶ 6) After initially disclaiming coverage, AMLIC declared insolvency and went into liquidation. (Id.) As a result, New York State Superintendent of Insurance Edward Muhl (the “Superintendent”) was appointed ancillary receiver for AMLIC. (Id.)
With AMLIC in receivership, Treadwell, CIGNA and Travelers negotiated over defense and indemnification for the Asbestos Claims. (Id. ¶¶ 6-7) In December 1991, the three companies reached an agreement (the “Interim Agreement”) dividing the relevant costs. (Id. ¶7 & Ex. 2) First, CIGNA and Travelers agreed to assume two-thirds and one-third, respectively, of defense costs retroactive to May 7, 1991. (Id.) Second, with Treadwell substituting for AMLIC — presumably due to the latter’s insolvency — the three companies agreed to assume the following proportions of responsibility for indemnification: CIG-NA, 71.4%; Treadwell, 17.2%; and Travelers, 11.4%. (Id.) According to Treadwell, this allocation of indemnification responsibility was based on the proportion of years CIGNA, AMLIC and Travelers, respectively, were each “on the risk” during the so-called Coverage Block — that is, between January 1, 1967 and July 1, 1986, or the period of time in which Treadwell had insurance coverage. (Treadwell Local Rule 56.1 Statement ¶ 30) The letter memorializing the Interim Agreement, however, does not specify the basis for the parties’ allocation. 6 (9/16/98 Johnson Aff. Ex. 2)
Notwithstanding the Interim Agreement, Treadwell pressed to obtain coverage for its losses as the number of Asbestos Claims against it multiplied. (Id. ¶ 8) First, the company asserted claims in the AMLIC liquidation proceedings. (Id. ¶ 8(a)) Second, it provided notice and asserted claims for defense and indemnity against USF & G, CU and Home Insurance. (Id. ¶ 8(b)) Finally, by letter dated February 7, 1992 from its insurance broker, Treadwell notified U.S. Fire about its “potential asbestos liability” and requested the carrier’s “immediate attention” to the matter. (Reilly Aff. Ex. D; see 9/16/98 Johnson Aff. ¶ 9)
U.S. Fire responded with a letter of its own, dated August 12, 1992. (Reilly Aff. Ex. E) In that letter, U.S. Fire rejected “any present duties” to indemnify or defend Treadwell, citing several grounds. (Id. at 4) First, noting its duty to indemnify only upon exhaustion of the underlying primary insurance, U.S. Fire contended that “there is no indication that underlying limits are at or near exhaustion.” (Id.) Second, acknowledging a duty to defend any suit alleging a covered loss not covered by other insurance, the carrier argued that “there is no indication that the alleged injury is not covered by underlying insurance.” (Id.) Finally, citing the “other insurance” provision in each of its policies, *86 U.S. Fire asserted that, “until all underlying insurance is paid, no duties can arise under the U.S. Fire policies.” (Id.)
In addition to providing these three reasons for rejecting “any present duties” under its policies, U.S. Fire raised several “additional serious questions of coverage” in its letter as follows:
To the extent “personal injury” as defined by the policy did not take place there would be no coverage for the claims. Further, to the extent “personal injury” as defined by the policy took place but was not within our policy period, there would be no coverage for the claim. We reserve the right to deny coverage on this basis.
.... Further, to the extent an “occurrence” as defined by the policies took place but was not within our policy period, there would be no coverage for the claims. We reserve the right to deny coverage on this basis.
In addition, both policies contain a contamination and pollution exclusion .... To the extent the damage alleged falls within the purview of this exclusion there would be no coverage for the claim. We reserve the right to deny coverage on this basis.
(Id. at 4-5) Further, U.S. Fire explicitly reserved “the right to assert any and all policy defenses including those discussed above and any not mentioned herein.” (Id.) In addition, the carrier asked Tread-well to keep it informed “if underlying limits are approaching exhaustion.” (Id.)
USF & G, CU and Home Insurance declined coverage of Treadwell’s claims also. (9/16/98 Johnson Aff. ¶ 10) Thereafter, USF & G commenced this action, naming Treadwell, CU and Home Insurance as defendants and seeking a declaratory judgment as to the nature and extent of its obligations to Treadwell. Treadwell filed an answer, counterclaims and cross-claims, in essence seeking a declaratory judgment regarding the carriers’ obligations to defend and indemnify and seeking also damages for breach of contract.
In May 1996, Treadwell impleaded Travelers, CIGNA, U.S. Fire and the Superintendent — the last as ancillary receiver for AMLIC — seeking a declaratory judgment as to the carriers’ obligations and, with respect to Travelers and CIGNA, seeking damages for breach of contract. To the extent relevant here, Treadwell’s initial third-party complaint acknowledged that “the limits of the underlying coverage for the excess policies” issued by U.S. Fire had “not yet been exhausted.” (1996 Compl. ¶¶ 56, 127) 7 Nevertheless, Tread-well sought “a judicial declaration that upon the exhaustion of the underlying coverage ... U.S. Fire is required to indemnify Treadwell.” (Id. ¶ 130)
D. Settlement with the Other Insurers
Following commencement of the third-party action, Treadwell entered into settlement negotiations with several of its insurance carriers. (E.g., 9/16/98 Mensch Aff. Exs. A1-A4) These negotiations led, in April and May 1997, to two settlement agreements. First, Treadwell and the Superintendent agreed to settle all of Tread-well’s claims with respect to AMLIC (the “AMLIC Agreement”). (Stip. ¶9 & Ex. E) Pursuant to this agreement, the Superintendent agreed to pay Treadwell $475,-000 from the New York Property/Casualty Insurance Security Fund (the “New York Insurance Fund”). (Stip. Ex. E ¶ 1) In exchange, Treadwell gave the Superintendent and all other relevant parties a general release “from any liability for any past, present or future claim whatsoever arising under any and all insurance policies which may have been issued by [AMLIC] to Treadwell, known or unknown” — including the policies in effect from 1970 through 1972. (Id. If 2)
*87 Second, Treadwell entered into a “Settlement and Claims Handling Agreement” (the “Settlement Agreement”) with USF & G, CU, Travelers and CIGNA. (Stip. ¶ 11 & Ex. F (“Agrmt.”)) To the extent relevant here, the Settlement Agreement allocates responsibility for payment of defense and indemnity costs arising from the Asbestos Claims among Treadwell, USF & G, CU, Travelers and CIGNA. 8 The Settlement Agreement specifies, first, that defense costs are to be allocated among the four settling insurers, with CIGNA assuming roughly three-quarters of the costs; Travelers, approximately 15%; and USF & G and CU, about 6% each. (Agrmt. at 10-14) Additionally, the Settlement Agreement designates CIGNA as the “Lead Insurer” and authorizes CIG-NA, in that capacity, to manage the defense and disposition of the Asbestos Claims on behalf of the other parties. (Id. at 29-32)
Second, and more significant for these motions, the Settlement Agreement allocates responsibility among Treadwell and the four settling insurers for indemnity payments. Specifically, the Settlement Agreement provides that CIGNA will assume 71.4% of the relevant liability; Travelers, 13.4%; and Treadwell, 15.2%, with USF & G and CU contributing toward that figure with respect to claims arising from the specific sites covered by their policies. (Id. at 16-18) The Settlement Agreement specifies also that upon exhaustion of any primary insurer’s liability, “Treadwell and/or Treadwell’s excess and/or umbrella insurers” will assume that insurer’s liability prospectively. (Id. at 20-21, 23) Finally, the Settlement Agreement notes that any funds received by Treadwell through settlement with the Superintendent or U.S. Fire are “for the sole benefit of Treadwell,” unless such funds exceed Treadwell’s obligations under the Settlement Agreement, in which case the excess is to be allocated “solely to or for the benefit of the Insurers.” (Id. at 27-28)
The Settlement Agreement specifies that the parties’ liability for both defense costs and indemnity is several. (Id. at 10, 16) However, it does not state explicitly the basis for its allocation of liability among the parties. Nevertheless, the Settlement Agreement includes as an exhibit a schedule listing the policies provided by the settling insurers to Treadwell (id. Ex. A), and from this list — along with provisions in the Settlement Agreement governing adjustments to the parties’ respective liabilities (e.g., id. at 20) — an allocation formula can be inferred: The shares of the indemnification payments assumed by CIGNA, Travelers and Treadwell under the Settlement Agreement correspond roughly to the proportion of time between January 1, 1967 and July 1, 1986 — the so-called Coverage Block — that each of CIG-NA, Travelers and AMLIC provided primary coverage to Treadwell. 9 (See also Treadwell Local Rule 56.1 Statement ¶¶ 30-31)
E. Correspondence Between Treadwell and U.S. Fire
In the months leading up to the Settlement Agreement, Treadwell notified U.S. Fire several times, directly and indirectly, about the ongoing negotiations with the other carriers, and invited U.S. Fire to join the developing agreement or to negotiate its own. (9/16/98 Mensch Aff. Exs. A1-A9) Following these invitations, representatives of U.S. Fire communicated with representatives of Treadwell — in person, by telephone and by letter — requesting details regarding the Settlement Agreement *88 and other information, including the liability limits of Treadwell’s primary insurance policies and the total payments made by Treadwell itself in connection with the Asbestos Claims. (E.g., id. Ex. A5) Tread-well provided this information, including, on March 19, 1997, “a chart reflecting Treadwell’s insurance coverage for the years 1967 — 1986, the years contained in the coverage block agreed among Tread-well, [CIGNA, Travelers, USF & G and CU].” (Id. Ex. A7; see also id. Exs. A6, A8)
On April 10, 1997, Treadwell’s counsel, Martin Mensch, Esq., wrote to U.S. Fire’s counsel, Vincent Reilly, Esq., questioning the support for “two separate positions” which Reilly had indicated in a previous conversation U.S. Fire “may take ... in attempt to avoid its obligations under the excess policies issued to Treadwell”: first, that U.S. Fire was not obligated to “drop down” and cover the Asbestos Claims until all of Treadwell’s primary insurance coverage was exhausted; and second, that the “so called [sic ] pollution exclusion applies.” (Reilly Aff. Ex. AA) By letter dated May 20, 1997, Reilly repliéd, pointing to “the ‘Other Insurance’ clause of the policies” as support for U.S. Fire’s exhaustion argument, and opining that the pollution exclusion clause “speaks for itself.” (Id Ex. BB)
F. The Parties’ Arguments for Summary Judgment
As noted, Treadwell purchased primary liability insurance from AMLIC for the years 1970,1971 and 1972, up to a limit of $300,000 in “products aggregate” for bodily injury claims. As of September 1998, Treadwell had paid or agreed to pay an aggregate of $944,984 in indemnity payments, allegedly pursuant to the Settlement Agreement. (11/17/98 Johnson Aff. ¶ 4; see also 9/16/98 Johnson Aff. ¶ 20; 11/2/98 Mensch Aff. ¶ 10) 10 Contending that this payment represents the amount it has paid in lieu of AMLIC for the three years that AMLIC provided primary coverage, Treadwell seeks a declaration that the AMLIC policies are now exhausted and, thus, that U.S. Fire must “drop down” to indemnify and defend the Asbestos Claims. 11 (Compl.lffl 34, 39)
In seeking summary judgment, U.S. Fire no longer presses the two positions taken by Reilly in his May 20, 1997 letter.
12
Instead, it cites
Stonewall Insurance Co. v. Asbestos Claims Management Corp-,
In support of its summary judgment motion and in response to U.S. Fire’s motion, Treadwell raises the following arguments:
(1) that U.S. Fire is barred by operation of various doctrines including waiver, equitable estoppel, judicial estoppel and collateral estoppel from arguing that Treadwell’s payments should be allocated to years prior to 1967; and
(2) that assuming U.S. Fire may raise the proration-to-the-insured argument, Treadwell can nevertheless allocate all its payments to the 1970-1972 period, for any one of three reasons:
(a) that the CGL policies Treadwell purchased from its primary insurers allow it to seek indemnification from any single insurer whose policy is triggered, subject only to the liability limits of that policy;
(b) that even assuming allocation of liability among multiple insurers is warranted, allocation of liability to Treadwell for periods during which it was uninsured is improper; or
(c) that U.S. Fire is bound by the terms of the Settlement Agreement and/or the AMLIC Agreement to accept allocation of some or all of Tread-well’s payments to the AMLIC policy periods.
One way or another, in short, Treadwell argues that U.S. Fire is bound by Tread-well’s agreement with its primary insurers to allocate liability based on the number of years each insurer was on the risk during the Coverage Block. Allocated in this manner, Treadwell argues, its $944,984 in payments exhausts the three AMLIC policies underlying U.S. Fire’s excess insurance policies, thus triggering U.S. Fire’s obligations to defend and indemnify.
II.
Summary judgment is mandated when “there is no genuine issue as to any material fact and ... the moving party is entitled to a judgment as a matter of law.” Fed.R.Civ.P. 56(c);
see Anderson v. Liberty Lobby, Inc.,
III.
Preliminarily, it is necessary to determine whether U.S. Fire is barred from arguing that the proration-to-the-insured approach applies. As noted, Treadwell argues that U.S. Fire is so barred by operation of various doctrines, including waiver, *90 equitable estoppel, judicial estoppel and collateral estoppel. I disagree.
A. Waiver
Treadwell’s contention that U.S. Fire waived its proration-to-the-insured argument is premised on Reilly’s failure to mention the argument in his May 20, 1997 letter to Mensch, or to challenge in any way the use of the Coverage Block as the alleged basis for allocating liability among Treadwell and its primary insurers.
(See
Treadwell Mem. at 22-24) To support its contention, Treadwell quotes
New York v. AMRO Realty Corp.,
Reilly’s letter, however, did not constitute a notice of disclaimer within the meaning of New York law. Specifically, it was not an “unequivocal, unambiguous written notice, properly served.”
Norfolk & Dedham Mut. Fire Ins. Co. v. Petrizzi,
B. Equitable Estoppel
Treadwell invokes also the doctrine of equitable estoppel, which “has been applied where the insured has been prejudiced as a result of unreasonable delay in failing to disclaim.”
Greater N.Y. Sav. Bank v. Travelers Ins. Co.,
Equitable estoppel is inapplicable, however, for several reasons. First, despite the exchange of correspondence between the parties with respect to the Asbestos Claims going back as far as 1992, it does not appear that Treadwell formally asserted a claim for indemnity against U.S. Fire until at least May 1996, when the company
*91
filed its initial third-party complaint. Even then, Treadwell did not allege that it was actually entitled to coverage from U.S. Fire; instead, Treadwell acknowledged that the AMLIC polices had “not yet been exhausted” and sought a judicial declaration that “upon the exhaustion” of those policies, U.S. Fire would be obligated to provide coverage. (1996 Compl. ¶¶ 56, 127,130) In these circumstances, U.S. Fire arguably had no duty to disclaim.
See U.S. Underwriters Ins. Co. v. Congregar tion B’Nai Israel,
Moreover, notwithstanding Treadwell’s claim that the Coverage Block was established in the December 1991 Interim Agreement (see Treadwell Local Rule 56.1 Statement ¶ 29), it does not appear that Treadwell notified U.S. Fire about any “coverage block” until March 1997, when Treadwell provided to U.S. Fire “a chart reflecting Treadwell’s insurance coverage for the years 1967—1986, the years contained in the coverage block agreed among Treadwell, [CIGNA, Travelers, USF & G and CU].” (9/16/98 Mensch Aff. Ex. A7) Before that date, there is no mention in the record of any coverage block—or, more to the point, any indication that U.S. Fire was made aware of such a concept— nor any evidence that Treadwell itself had definitively settled upon 1967 to 1986 as the relevant period. Indeed, in its initial third-party complaint, Treadwell identified at least two insurance policies which it believed were in effect prior to 1967. (See 1996 Compl. ¶ 27) Additionally, the Superintendent produced evidence in July 1996 that Treadwell had filed claims for coverage based on AMLIC policies going back as far as 1947. (See Reilly Aff. Ex. B:I)
At the same time, Treadwell was on notice prior to executing the Settlement Agreement that U.S. Fire believed Tread-well’s insurance coverage between the 1940s and 1967—or the lack thereof—was relevant to the allocation question. In a meeting on March 12, 1997, for instance, U.S. Fire’s counsel, Reilly, asked Treadwell’s counsel, Mensch, about Treadwell’s liability policies before 1968, because “these policies potentially were applicable to the asbestos claims.” (Reilly Aff. ¶ 46) Further, from additional conversations with Reilly prior to May 20,1997, “Mensch knew ... that U.S. Fire was taking the position that Treadwell could not unilaterally decide to select an AMLIC policy year and allocate all amounts paid into that year because under New York law, the loss should be spread over the period of exposure to claim or death.” {Id. ¶48)
In fact, Treadwell arguably should have known as far back as 1992 that U.S. Fire might assert a defense relating to the method of allocating liability to different policy periods. In U.S. Fire’s August 12, 1992 letter rejecting “any present duties” to provide coverage'—a letter to which U.S. Fire referred repeatedly in subsequent correspondence {see, e.g., id. Exs. G-M, O-P)—the insurer reserved the right to make the type of argument it makes now. {See id. Ex. E) To be sure, U.S. Fire did not refer explicitly to “allocation” or “pro-ration-to-the-insured,” but it did state unequivocally that there would be no coverage for personal injuries or occurrences that took place outside the periods its policies were in effect. {See id. at 5)
Even assuming arguendo that U.S. Fire unreasonably delayed raising the allocation argument, equitable estoppel is unwarranted because Treadwell was not *92 prejudiced by this delay. Treadwell claims that it entered the Settlement Agreement in reliance upon its assumption that “the Coverage Block there provided was acceptable to all insurers—including U.S. Fire.” (9/16/98 Mensch Aff. ¶ 5) Had Treadwell been advised by U.S. Fire otherwise, counsel alleges, “Treadwell’s stance would have been different—the matter would certainly have been the subject of negotiation and a different outcome may well have resulted.” (Id.)
Treadwell cannot have it both ways. Notwithstanding its claims of reliance, in contending that U.S. Fire unreasonably delayed raising the allocation argument, Treadwell asserted that the Coverage Block was established as early as December 1991, in the Interim Agreement—and that the Interim Agreement was, in turn, incorporated into the 1997 Settlement Agreement.
(See
Treadwell Local Rule 56.1 Statement ¶ 31) Thus, Treadwell appears to have been committed to the Coverage Block even before it notified U.S. Fire about the Asbestos Claims, in February 1992, and even longer before it first mentioned to U.S. Fire the idea of a “coverage block,” in March 1997. Accordingly, Treadwell’s claims of reliance on U.S. Fire’s alleged silence with respect to the Coverage Block ring hollow.
Cf. Gilbert Frank,
C. Judicial Estoppel
Next, Treadwell invokes judicial estoppel. Judicial estoppel “forbids a party from advancing contradictory factual positions in separate proceedings.”
AXA Marine & Aviation Ins. (UK) Ltd. v. Seajet Indus. Inc.,
Here, Treadwell contends that judicial estoppel applies by virtue of a position advanced in 1986 by North River Insurance Company (“North River”), a U.S. Fire “affiliate,” in a case before the Superior Court of New Jersey styled
Madsen & Howell, Inc. v. Sentry Insurance Company,
No. L-021632-55 (Law Div., Middlesex County). (See 9/17/98 Warshauer Aff. ¶ 14 & Ex. K) In that case, which also involved insurance for personal injuries arising from exposure to asbestos, North River argued,
inter alia,
in favor of the approach
to
allocating liability taken by the U.S. Court of Appeals for the D.C. Circuit in
Keene Corp. v. Insurance Co. of North America,
Treadwell’s argument is without merit, however, for three reasons.
13
First, and most significant, it is not apparent that the position taken by North River in
Madsen & Howell
is inconsistent with the position advanced by U.S. Fire here. To be sure, North River endorsed a precedent that
*93
would appear, in most respects, to support Treadwell’s present position. Nevertheless, at the same time, North River argued explicitly for proration of the defendant insurers’ obligations based on the number of years each insurer was on the risk.
(See, e.g., id.
at 15-16, 19-20) Indeed, the very title of the section of North River’s brief from which Treadwell quotes states as much explicitly: “POINT II: THE COVERAGE AND DEFENSE OBLIGATIONS TO BE AFFORDED BY EACH INSURER SHOULD BE ALLOCATED BASED UPON THE YEARS OF COVERAGE EXTENDED BY EACH INSURER DURING THE PERIOD BETWEEN INITIAL EXPOSURE AND MANIFESTATION.”
(Id.
at 15) Thus, the two positions are not irreconcilable.
Cf. Simon,
Second, whatever inconsistency there is between the positions advanced by North River and U.S. Fire pertains to the construction of insurance policies. To the extent relevant here, however, such an issue is one of law, not fact.
See, e.g., K. Bell & Assocs., Inc. v. Lloyd’s Underwriters,
Finally, it is Treadwell’s burden to show that the New Jersey Court adopted North River’s argument “in some manner.”
AXA Marine,
D. Collateral Estoppel
Finally, Treadwell argues that U.S. Fire is collaterally estopped by the Supreme Court of Pennsylvania’s decision in
J.H. France Refractories Co. v. Allstate Insur-
*94
anee Co.,
Because
J.H. France
was a Pennsylvania case, Pennsylvania law applies to the question of whether U.S. Fire is collaterally estopped.
See Migra v. Warren City Sch. Dist. Bd. of Educ.,
Notwithstanding that several requirements for collateral estoppel are met here, to give
J.H. France
binding force in this case would be “unfair and inappropriate,” for two reasons.

was decided under Pennsylvania law, and relied exclusively for its reasoning on public policy and on the D.C. Circuit’s decision in
Keene. See J.H. France,
IV.
As noted, U.S. Fire and Treadwell have stipulated that to the extent an Asbestos Claimant was injured by exposure to asbestos, he was injured at all points in time from initial exposure through the date his claim was filed or he died. (Stip-¶ 3) Because Treadwell engaged in asbestos-related activities as early as the 1940s, the parties’ agreement means that for many of the Asbestos Claims, injury began before Treadwell first obtained insurance in 1967. In essence, therefore, the question at the heart of this case is whether this uninsured period is relevant in determining which entities are liable for the Asbestos Claims. That is, is Treadwell responsible for paying some share of the over-all liability attributable to the period before 1967? If so, some portion of the $944,984 that Treadwell has paid or promised to pay pursuant ,to the Settlement Agreement presumably would have to be allocated to the years before 1967, that portion to be determined on the basis of when each underlying claimant’s injury began. Allocated in such a manner rather than entirely to the AMLIC policy period, Treadwell’s payments would probably not yet exceed $300,000 for any of the AMLIC policy years, and U.S. Fire’s excess policies would not yet be triggered.
A. Allocation in the First Instance ?
Before considering whether any liability should be allocated to Treadwell for the period prior to 1967, however, it is necessary to consider an analytically prior issue: whether this court can allocate liability at all. Treadwell contends that under the CGL policies it purchased from its primary insurers, it is permitted to demand full coverage for continuous injury claims from any one insurer whose policy is triggered, subject only to that insurer’s liability limits. From this entitlement, Treadwell reasons, it follows that the company can allocate all its payments to the 1970-1972 period, notwithstanding the absence of insurance prior to 1967, thus exhausting the AMLIC policies and triggering U.S. Fire’s coverage. (See, e.g., Treadwell Mem. at 33-38) In response, U.S. Fire contends that each insurer is responsible for only its pro rata share of the liability for each Asbestos Claim. Thus, U.S. Fire concludes, Treadwell cannot “arbitrarily” decide what amount of liability is attributable to the AMLIC policy years; instead, Lability for each Asbestos Claim must be allocated in the first instance across all the years the Asbestos Claimant’s injury occurred, including the years prior to 1967. (See, e.g., U.S. Fire Mem. at 9-14)
Although much ink has been spilled during the last two decades on the question of whether allocation of liability
*96
for continuous injury is appropriate, no consensus has emerged.

Allocation of Coverage Re
sponsibilityCourts are divided between the approaches urged by the parties here. Some courts have adopted the pro rata approach urged by U.S. Fire, which allocates liability for a particular claim among all triggered policies in the first instance.
See, e.g., Lafarge Corp. v. National Union Fire Ins. Co.,
Other courts have concluded that each triggered policy is. jointly and severally liable for the insured’s liability and, thus, that the insured can collect under any one triggered policy the full amount of indemnity that is due, subject only to that policy’s liability limits.
See, e.g., Prudential Lines,
Notwithstanding the debate over these two approaches, the difference between them for the purposes of this ease is not as great as Treadwell and U.S. Fire appear to believe. Under either approach, an insurer is liable for only its share, however calculated, of the over-all liability.
See, e.g., Koppers,
Although allocation occurs under both approaches, the decision to adopt one approach rather than the other can have at least two financial consequences for the parties in a case. First, as noted, the choice determines whether the insured or its insurers bears the risk of insurer insolvency.
See Koppers,
B. Prudential Lines
Even though Treadwell’s ultimate conclusion — that it is not liable for the years it was uninsured — does not follow from its starting premise — that joint and several liability applies — there is need nevertheless to consider its arguments against allocation, if only for formalistic reasons. That is, if the joint and several approach applies, as Treadwell argues, another court in a later proceeding could still consider the proration-to-the-insured issue and order Treadwell to contribute for the years it lacked insurance. But, under that approach, this court, in this proceeding, could not do either.
The logical starting point for this inquiry is the Second Circuit’s recent decision in
Prudential Lines.
17
In that case, the
*98
trustee of a shipping line in bankruptcy, Prudential Lines, Inc. (“Prudential”), sued the American Steamship Owners Mutual Protection and Indemnity Association (“American Club”), seeking indemnification for asbestos-related bodily injury claims asserted against Prudential. For the most part, American Club insured Prudential for the full period of the underlying claimants’ injuries, so the issue of allocation among multiple
insurers
was not presented.
See Prudential Lines,
The Bankruptcy Court and the District Court both held in favor of Prudential on the allocation issue, basing their decisions in large part on the plain language of the policies, which provided for indemnification of “any loss” that Prudential “shall become liable to pay.”
See In re Prudential Lines, Inc.,
The Court began its analysis with a discussion of the two different approaches to allocation.
See Prudential Lines,
After listing these considerations, the Court turned to the facts of the case before it, noting, with a textual sigh of relief, that “Fortunately, a number of factors that *99 often complicate the inquiry are absent here.” Id. at 85. That is, Prudential had no periods of self-insurance and, for virtually the entire span of relevant years, only one insurer. See id. Thus, if joint and several liability applied, there was no danger that American Club would be saddled with more than its share of liability — or with liability that should have been assumed by Prudential itself — and no danger of additional litigation. See id. To the extent American Club wanted to allocate liability among its own policies, it could develop an “internal allocation mechanism” to do so — in other words, allocation was an issue merely of bookkeeping. Id. at 85-86.
Noting that the real “financial significance” of the allocation issue lay in its impact on the number of deductibles that would apply to each claim against Prudential, the Second Circuit then concluded:
Given: (i) the policy’s broad language covering “any loss [or] damage” which Prudential becomes liable to pay resulting — presumably even in part — -from injuries occurring during the policy period; (ii) the absence of a contractual intent to require allocation of liability among policies in the first instance; and (iii) the lack of any compelling policy or equitable considerations favoring allocation, we decline to read the policies in a way that would have the (probably unintended) effect of multiplying the deductibles applicable to each claim.
We hold that, in the circumstances presented, Prudential has the right to demand that a policy pay full coverage for each insurance claim in which the underlying Claimant suffered ... asbestos injury during the policy period.
Id.
at 86 (emphasis added) (alteration in original);
cf. Reichhold Chems., Inc. v. Hartford Accident & Indem. Co.,
The circumstances of this case support a result different from the one reached in
Prudential Lines.
Whereas Prudential was insured by one carrier for virtually the entire period of injury in
Prudential Lines,
the injuries in this case spanned a period in which Treadwell was insured by many carriers, under both primary and excess policies, and in which Treadwell lacked insurance altogether. Thus, “a number of factors that often complicate the inquiry” are present here.
Prudential Lines,
In fact, only one thing turns on the choice of which approach to apply in the present case: whether there will be a second round of litigation. If the joint and several approach were applied, U.S. Fire would be obligated to indemnify Treadwell for its share of future losses. But, as noted above, when the dust settled and the Asbestos Claims were paid in full, U.S. Fire would have the right to bring Tread-well back to court to determine whether the proration-to-the-insured approach applied. The outcome of that second round of litigation, based on the same record as is presented here, would then determine whether U.S. Fire’s policies should have been triggered in the first place; that, in turn, would determine whether Treadwell’s loss should be re-allocated from U.S. Fire back to Treadwell. Thus, the only consequence of applying joint and several liability would be to postpone resolution of the central dispute in this case, at significant additional expense to the parties, not to mention the effort to be expended by the court. The law does not require such a perverse result.
*100
To be sure, like the American Club policies in
Prudential Lines,
the policies at issue here employ “broad language” of indemnification.

C. Treadwell’s Additional Arguments
Notwithstanding the overwhelming considerations of convenience and common sense favoring allocation in the first instance here, analysis of the Second Circuit’s opinion in Prudential Lines does not exhaust the necessary inquiry. Treadwell presses several arguments addressed to contractual intent and interpretation that were not treated explicitly by the Prudential Lines Court. 20 Because, under most circumstances, parties can contract around even convenience and common sense, it is therefore necessary to consider whether any of these arguments has merit.
Treadwell’s first argument relies on the putative “drafting history” of the CGL policies. Specifically, Treadwell submits several internal documents—memo-randa and minutes of meetings from the 1960s and 1970s—from the National Bureau of Casualty Underwriters and the Insurance Services Office, industry associations of which U.S. Fire is or was a member.
(See
9/17/98 Warshauer Aff. ¶¶ 1-13 & Exs. A-I) To the extent relevant here, these documents contain various statements along the following lines: (1) that, in cases of cumulative injury, “it is possible that more than one policy will afford coverage”
(id.
¶ 8 & Ex. E;
see also id.
¶ 7
&
Ex. D); (2) that “[t]here is no proration formula in the policy, as it seemed impossible to develop a formula which would handle every possible situation with complete equity”
(id.
¶ 9 & Ex.
*101
F); and (3) that “each carrier on the risk during any part of [the period of time an asbestosis condition developed] could be fully responsible for the cost of defense and loss.”
(Id.
¶ 11 & Ex. H);
see also Owens-Illinois,
Treadwell’s argument is unpersuasive, however, for two reasons. First, there is “inherent mischief’ in heavy reliance on selected statements from industry meetings and memoranda.
Beeson v. Fishkill Correctional Facility,
Second, even if one were to give significant weight to the statements of the CGL drafters, the statements at issue do not unambiguously support Treadwell’s argument for joint and several liability. To say that it is “possible” that more than one policy will “afford” coverage is not to say that any one policy is actually hable in full in the first instance. Nor is the statement that each carrier on the risk during any part of an injury “could” be fully responsible for the loss necessarily anything more than a prediction of what courts might do, rather than an expression of what courts should do. Finally, to say that “[t]here is no proration formula in the policy” is to say nothing more than the obvious, that the CGL policies do not definitively settle what to do in a situation like the present one.
Cf. Owens-Illinois,
Next, Treadwell contends that, under New York law, the absence of a “pro rata limitation” in U.S. Fire’s policies means that U.S. Fire cannot limit its obligations to a share of Treadwell’s liabilities. (Treadwell Mem. at 38) In essence, Tread-well argues that the “absence of a contractual intent to require allocation ... in the first instance,”
Prudential Lines,
Here, Treadwell relies in major part on the New York Court of Appeals decision in
York-Buffalo Motor Express v. National Fire & Marine Insurance Co.,
“Most policies of fire insurance contain a clause providing that the insurer shall not be liable for any greater proportion of any loss which may occur than the amount named in the policy shall bear to the entire amount of insurance upon the property.... By inserting this clause the insurer limits the amount of recovery upon that particular policy to the proportionate amount which that policy bears to the entire amount of the policies. In the absence of such a clause, the insured could recover the whole amount from any one of the insurers, and leave him to obtain contribution from the other insurers. ”
Id.
at 473,
Treadwell’s reliance on
York-Buffalo
is misplaced. First, given that the plaintiff in that case had recovered most of its loss from National and was seeking only the remainder from Rhode Island, the language quoted is technically dictum with respect to whether allocation in the first instance is warranted. Second, in the 54 years since
York-Buffalo
was decided, the case has been cited in only three cases,
see Lewis Mach. Co. v. Aztec Lines,
Treadwell’s final argument is premised on the
contra proferentem
rule, which states that “ ‘where a policy of insurance is so framed as to leave room for two constructions, the words used should be interpreted most strongly against the insurer.’ ”
Haber v. St. Paul Guardian Ins. Co.,
V.
• [20] The conclusion that allocation in the first instance is warranted presents, in turn, the question of whether Treadwell’s payments pursuant to the Settlement Agreement should be allocated to all the years in which it actually or effectively lacked insurance, i.e., to the AMLIC policy years and the years prior to 1967. As noted, the answer to this question depends on whether Treadwell should be treated as a self-insurer for the years prior to 1967. Under the Second Circuit’s decision in Stonewall, it should.
In
Stonewall,
a case decided under New York (and Texas) law, the National Gypsum Company (“NGC”), a former asbestos product manufacturer, and certain of its liability insurers sought declaratory relief clarifying the extent to which NGC was entitled to indemnification for asbestos-related claims asserted against it.
See Stonewall,
On appeal, neither NGC nor the insurers objected to the District Court’s decision to allocate in the first instance, or to the time-on-the-risk formula used by the District Court to determine the carriers’ respective shares.
See id.
NGC, however, objected to the proration-to-the-insured approach, arguing that the policies promised to pay “all sums” for which NGC became liable because o.f bodily injury and did not contain any provision “permitting the Insurers to shift a portion of a covered loss back to the insured for uninsured periods.”
Id.
Notwithstanding these arguments, the Second Circuit affirmed. Praising the New Jersey Supreme Court’s decision in
Owens-Illinois,
which adopted the proration-to-the-insured approach on policy and equity grounds,
see Owens-Illinois,
Treadwell makes various arguments as to why the Second Circuit’s decision in Stonewall is wrong or not controlling. Most of these arguments confuse the question of whether to prorate to an insured for uninsured periods with the analytically distinct question of whether to allocate in the first instance, and thus are inapplicable or have been rejected already. Two of Treadwell’s arguments, however, warrant consideration.
Treadwell’s first argument, that the “precedential effect of
Stonewall”
was limited by
Prudential Lines
(Treadwell Reply Mem. at 12-14), is arguably correct, but beside the point. As discussed above, the central issue in
Prudential Lines
was whether to apply the pro rata allocation approach or the joint and several approach. Prudential was insured for the full period of injury, so the Court had no occasion to pass directly on the proration-to-the-insured approach. Nevertheless, in a footnote, the Court characterized
Stonewall
in a manner which implies that New York courts are not required to apply the proration-to-the-insured approach: In
Stonewall,
the
Prudential Lines
Court wrote, “[w]e held that the district court
did not err
in allocating liability to the insured ... for periods in which the insured lacked coverage (at least during the period when coverage for asbestos risk was available).”
Prudential Lines,
Whether the proration-to-the-insured approach is required or merely permitted, however, it should be applied here. To the extent relevant, the facts of this case are almost identical to those in
Stonewall.
Thus, the Court’s holding, even if not controlling, warrants substantial weight. In any event, applying the proration-to-the-insured approach in this case is supported by sound considerations of equity. Tread-well made a decision to go without insurance for the years prior to 1967, and this decision should have consequences. Otherwise, Treadwell would receive the same treatment as an identically situated compa
*105
ny that chose to purchase insurance for the full period. As Judge Weinstein explained with characteristic force and clarity in
Uniroyal,
“A firm that fails to purchase insurance for a period ... is self-insuring for all the risk incurred in that period; otherwise it would be receiving coverage for a period for which it paid no premium. Self-insurance is called ‘going bare’ for a reason.”
Uniroyal,
Second, Treadwell notes that the
Stonewall
Court did not directly address the issue of what formula to use when allocating, and argues that allocation should be done here “by policy limits” rather than time on the risk.
{See
Tread-well Mem. at 43) Although Treadwell’s argument finds support in some cases,
see, e.g., Morgan, Olmstead, Kennedy & Gardner, Inc.,
In contrast, the time-on-the-risk method has been applied by the vast majority of courts allocating liability, including every court to have considered the issue under New York law.
See NL Indus.,
VI.
One final issue requires consideration: what impact, if any, Treadwell’s settlements with its other insurers have on the present dispute. As noted, Treadwell en *106 tered into two settlements with its other insurers. First, pursuant to the AMLIC Agreement, Treadwell settled all claims against AMLIC for a single payment of $475,000 from the New York Insurance Fund (the “AMLIC Payment”). That the AMLIC Payment was made by the New York Insurance Fund and not by AMLIC itself is immaterial for present purposes. Second, pursuant to the Settlement Agreement, CIGNA, Travelers and Treadwell assumed 71.4%, 13.4% and 15.2%, respectively, of Treadwell’s total liability. 23 Under the Settlement Agreement, Treadwell is the sole beneficiary of the AMLIC Payment.
Treadwell asserts that both agreements are binding on U.S. Fire for allocation purposes. First, with respect to the AM-LIC Agreement, Treadwell argues that because AMLIC contracted to cover the 1970-1972 period, the AMLIC Payment of $475,000 should be allocated to those years. (See Treadwell Mem. in Opp’n at 7 n. 6; see also Treadwell Mem. at 19-20) Second, with respect to the Settlement Agreement, Treadwell contends that because its share of the total loss was based on the number of years AMLIC was on the risk, its $944,984 of payments should be allocated to those years only. (See Treadwell Mem. 16-20) U.S. Fire disputes both propositions, contending that the liability for each claim that Treadwell assumed under the Settlement Agreement should be allocated pro rata to all years of the claimant’s injury in which Treadwell was actually or effectively (because of AM-LIC’s insolvency) uninsured, including periods before 1967. (See U.S. Fire Mem. at 15-18; see also U.S. Fire Reply Mem. at 12-14)
A. The AMLIC Agreement
The first question to be resolved is whether a primary insurer’s agreement to pay a portion of the total liability arising from continuing injury is binding on the insured and its excess insurers for allocation purposes. That is, in determining whether primary insurance coverage has been exhausted, thereby triggering excess coverage, what amount should be allocated to the primary insurer’s policy period: the amount it actually paid or the amount it would have been contractually obligated to pay had it not settled? The answer to this question determines not only whether the AMLIC Payment should be allocated to the AMLIC policy period, but also whether the shares assumed by CIGNA and Travelers pursuant to the Settlement Agreement are properly allocated to their respective periods. 24
Treadwell’s argument that a primary insurer’s settlement should be allocated to that insurer’s policy period finds some support in the case law, all of which comes, coincidentally, from this district.
See Maryland Cas. Co. v. W.R. Grace & Co.,
No. 88 Civ. 2613(JSM),
To see why allocating an insurer’s settlement amount to its policy period promotes settlement, consider the following hypothetical. Assume that several people suffering from asbestos-related diseases sue a company, C, exactly 10 years to the day after they were initially exposed to asbestos. Assume further that C was insured in only the first three years, or 30%, of the 10-year period of the claimants’ injuries. In those three years, C was covered by primary policies, issued by insurer P and covering up to $150,000 in liability per year — $450,000 in the aggregate for all three years. Also during those years, C was covered by excess policies, issued by insurer E and triggered by exhaustion of the underlying primary insurance. Finally, assume that the claimants’ injuries thus far have cost C $1 million in liability payments and that there is a chance the total liability will eventually exceed $2 million.
Now consider three scenarios. In Scenario 1, the parties cannot reach settlement and bring their dispute to a court, which allocates liability pro rata by time on the risk, with C contributing for the years it was uninsured. In this scenario, therefore, P will assume $300,000, or 30%, of the existing $1 million liability and 30% of the next $500,000 in liability, at which point it will owe the maximum amount allowable under its policies ($450,000); C will assume 70% of all liability; and E will be off the hook until the total liability reaches $1.5 million, when P’s policies will be exhausted. At that point, E will assume 30% of all subsequent liability.
In Scenario 2, P settles with C for the full coverage under P’s policies, $450,000. Although this amount exceeds P’s contractual liability of $300,000 at the time of settlement, it is plainly binding on P and C with respect to the first $1 million in liability; thus, of the first $1 million in liability, P will assume $450,000 and C will assume $550,000. C’s and E’s respective shares of the liability in excess of $1 million, however, will differ depending on whether P’s $450,000 is allocated entirely to its policy period or not. If it is — that is, if the settlement is binding on C and E for allocation purposes — the excess policies will be triggered, even though the total liability is only $1 million. Thus, E and C will assume 30% and 70%, respectively, of all liability in excess of $1 million. If the settlement is not binding for allocation purposes, E would not be liable until the total liability exceeded $1.5 million, at which point it would assume 30% of all future liability. Thus, C would have to pay all losses until the total reached $1.5 million, and 70% of liability thereafter.
In Scenario 3, P settles with C for $150,-000, less than both P’s maximum exposure and its legal share. C would thus be liable for $850,000 of the first $1 million in losses. Again, however, C’s and E’s respective shares of the liability in excess of $1 million would differ depending on whether the settlement is binding for allocation *108 purposes. If the settlement is binding, C would have to assume the next $1 million in losses; only then, when the total liability exceeded $2 million, would E be liable for 30% of future losses. If the settlement is not binding, however, E’s liability would be triggered when the total losses reached $1.5 million. Thus, again, C would have to pay all losses until the total reached $1.5 million, and 70% thereafter.
Table 1 depicts each party’s liability under each of these three scenarios, and the effects in Scenarios 2 and 3 of treating P’s settlements as either binding (shaded areas) or not binding (unshaded areas) for allocation purposes. In addition, Table 1 lists for each scenario the parties’ respective liability shares when the total loss equals $2 million.
*109 [[Image here]]
As this hypothetical illustrates, if C’s settlement with P is not binding for allocation purposes, C will have little or no incentive to settle. If P settles for more than its legal share (Scenario 2), C will have to pay the same ($1.4 million) as it would have owed in the absence of a settlement. If P settles for less than its legal share (Scenario 3), C will owe more than it would have in the absence of a settlement. Thus", C stands to gain nothing by settling. 25 In contrast, if P’s settlement is *110 binding for allocation purposes, C has the chance of obtaining through settlement a better outcome than it could by going to court.
Of course, because P’s exposure is capped at $450,000, C’s gain is E’s loss. That is, if P settles for more than its legal share (Scenario 2) and P’s settlement is binding for allocation purposes, E will end up paying more than it would have in the absence of a settlement ($300,000 versus $150,000). But this consequence is not as unfair as it might first appear. For one thing, if P settles for less than its legal share (Scenario 3), E stands to gain at C’s expense; that is, if total liability reaches $2 million, E will end up owing nothing as opposed to $150,000. In such a situation, it is unlikely the excess carrier would argue against treating P’s settlement as binding for allocation purposes. 26 Moreover, absent collusion on the part of C and P, there is nothing preventing E from participating in the settlement negotiations with both of the other parties. Indeed, if any settlement with P would be binding for allocation purposes, E would have an incentive to participate in settlement negotiations to avoid an increase in its liability. With both insurers participating in settlement negotiations, the parties are likely to reach an agreement that approximates that the outcome would have been in the absence of settlement and without incurring the litigation costs of reaching that result.
In the present case, there is no evidence of collusion between Treadwell and AMLIC (or, more precisely, the Superintendent). To the contrary, U.S. Fire was given notice of the ongoing negotiations and was invited to participate. (See, e.g., 9/16/98 Mensch Aff. Ex. A5) Under the circumstances, therefore, the $475,000 AMLIC Payment should be allocated entirely to the 1970-1972 period. 27
B. The Settlement Agreement
Having decided that the $475,000 AMLIC Payment—which was made directly to Treadwell-—should be allocated to the 1970-1972 period, I need decide only whether Treadwell’s payments in excess of that amount, totaling $469,984, also should be allocated to the 1970-1972 period. As noted, Treadwell argues that because its share of the total loss under the Settlement Agreement was based on the number of years AMLIC was on the risk, it should be permitted to allocate its payments to AMLIC’s policy period. I disagree.
Treadwell relies here primarily on the Second Circuit’s decision in Stonewall,
28
*111
In that case, the insured, NGC, entered into an agreement, known as the “Wellington Agreement,” with 33 other former asbestos products producers and 16 insurers.
See Stonewall,
Little more than three years after the Wellington Agreement was executed, the claims-handling facility established by the agreement was dissolved. See id. Simultaneously, NGC entered into another agreement, the “CCR Producer Agreement,” with ,21 former asbestos products producers, all of which had been parties to the Wellington Agreement. See id. Like the Wellington Agreement, the CCR Producer Agreement established a claims-handling facility with responsibility for evaluating, defending and settling asbestos-related bodily injury claims against the subscribing producers. See id. Again, the costs incurred by the facility were allocated to the subscribing producers according to a formula, which formula eventually was revised so that producers would pay a share of only those claims in which they were named. See id. No insurer was a signatory to the CCR Producer Agreement, but several insurers who had been signatories to the Wellington Agreement entered into separate agreements with the producers concerning the new claims-handling facility. See id. In addition, notwithstanding the dissolution of the first claims-handling facility, the insurance coverage provisions of the Wellington Agreement remained in effect. See id. at 1189.
The insurers seeking relief in Stonewall were not signatories to the Wellington and CCR Agreements. See id. Thus, the District Court had to determine “whether NGC’s decision to resolve the asbestos-related bodily injury claims against it by joining these claims-handling facilities was reasonable, and whether all amounts paid by NGC pursuant to these agreements ... could be recovered from these non-signatory Insurers under the terms of their policies.” Id. The District Court found, in the Court of Appeals’s words, that NGC “enjoyed a number of benefits” as a result of its participation in the claims-handling facilities and held that NGC’s decision to participate was reasonable. Id. at 1207. Notwithstanding that the agreements allocated to NGC losses for some claims in which it was not even a named defendant, the Second Circuit affirmed. NGC’s payments, the Court held, “were ‘consistent with NGC’s rights under its policies to enter into reasonable and good faith settlements.’ ” Id. (quoting the District Court’s opinion). Indeed, the Court argued, had NGC declined to join the claims-handling facilities, the insurers likely would have complained “that NGC’s failure to use these settlement mechanisms was unreasonable.” Id.
Treadwell’s rebanee on Stonewall is misplaced. The question in Stmeivall was effectively whether the non-settling insurers were bound by the sums paid by NGC to the asbestos claimants through the claims-handbng facibties. To be sure, NGC did not enter into agreements with the claimants themselves, or even pay *112 them directly. But the costs NGC incurred were directly related to the resolution of the underlying claims. In essence, the Court treated the claims-handling facilities as NGC’s agents for the purposes of resolving the underlying claims and held that the facilities’ settlements of the underlying claims were within the terms of NGC’s insurance policies. Crucially, the non-settling insurers were not bound by the terms of NGC’s settlements with its other insurers. Indeed, as discussed in the previous section of this opinion, the non-settling insurers in Stonewall were allocated shares of the loss based on the time each was on the risk.
However, in the present case, the Settlement Agreement itself has nothing to do with resolving the Asbestos Claims themselves. Instead, the agreement is concerned primarily with how to allocate the separately determined costs of the underlying claims among Treadwell and its other insurers. Thus, the Settlement Agreement does not compromise the liability insured by the U.S. Fire policies, which indemnify Treadwell for losses due to the settlement of covered claims themselves. Moreover, whereas the agreements in
Stonewall
saved transaction costs that would otherwise have been borne by the insurers, the Settlement Agreement in this case does not produce similar efficiency gains. Thus, while the non-settling insurers in
Stonewall
might have complained had NGC not entered into the Wellington and CCR Producer Agreements,
see Stonewall,
Nor, as an additional matter, would allowing Treadwell to allocate its own payments to the 1970-1972 period further the worthy goal of promoting settlement. Assuming that Treadwell’s share of the total loss was, in fact, based on the proportion of years AMLIC was on the risk during the Coverage Block — a proposition nowhere stated in the Settlement Agreement — Treadwell received a windfall in the Settlement Agreement. That is, CIGNA and Travelers assumed responsibility for a substantial amount of the loss that, in the absence of settlement, would have been borne by Treadwell. Thus, Treadwell would have had sufficient incentive to settle even if it had known that its payments would have to be allocated across all years it was uninsured. To allow Treadwell to allocate all its payments to the AMLIC policy period, therefore, would be to give Treadwell a double windfall, the second at U.S. Fire’s expense, without any countervailing justification.
In short, while Treadwell can allocate $475,000 of its payments — the amount of the AMLIC Payment — to the 1970-1972 policy period, the remainder of its payments must be allocated across all the years of each claimant’s injury in which Treadwell was uninsured, including the period prior to 1967.
VII.
The consequences of this ruling are as follows. First, $475,000 of Treadwell’s payments are allocated to the 1970-1972 policy period, prorated evenly across the three years. Second, notwithstanding Treadwell’s complaint of impracticability Csee Treadwell Mem. in Opp’n at 7-11), Treadwell’s payments in excess of $475,000 (currently $469,984) are allocated pro rata across all years in which Treadwell was uninsured during each Asbestos Claimant’s period of injury.
The parties have not submitted comprehensive data with respect to when each Asbestos Claimant was first exposed to asbestos at a Treadwell powerhouse. Accordingly, it is impossible for me to determine with certainty how much of Tread-well’s payments in excess of $475,000 are attributable to the 1970-1972 period, when the U.S. Fire policies were in effect. Nevertheless, it can be inferred from the parties’ arguments and from the limited data that is in the record (see Reilly Aff. Ex. D), that according to the rulings announced in *113 this opinion, none of AMLIC’s policies has yet been exhausted, and none of U.S. Fire’s obligations to defend or indemnify triggered. That is, Treadwell’s payments and the portion of the AMLIC Payment attributable to any one year of the AMLIC policy period do not yet exceed $300,000.
Thus, summary judgment is granted to U.S. Fire, contingent upon a determination that the payments attributable to the AM-LIC policy period do not in fact exceed $300,000 in any one year. The parties are ordered to determine, based on the relevant data and the rulings set forth in this opinion, the actual amount of Treadwell’s payments in excess of $475,000 attributable to the AMLIC policy years and to settle judgment accordingly. To the extent that the relevant data are unavailable — -that is, if some of the Asbestos Claimants’ initial exposure dates cannot be determined — the parties are directed to use random sampling or other statistical methods to allocate those claims based on the known data.
Cf. UNR Indus., Inc. v. Continental Cas. Co.,
i|< ‡ ‡ ;¡:
For the reasons stated above, Tread-well’s motion for summary judgment is denied, U.S. Fire’s motion is granted and Treadwell’s amended third-party complaint is dismissed, all contingent upon a determination based on the rulings set forth in this opinion that none of the AMLIC policies has been exhausted. I will confer with the parties to establish a schedule for settling a judgment.
Notes
. "Slip.” refers lo the "Stipulation of Material Facts Not in Dispute for Purpose of Summary Judgment Motions," so ordered August 26, 1998.
. "Compl." refers to the Amended Cross-Claim and Amended Third-Party Complaint of Treadwell Corporation, dated August 27, 1997.
. The parlies agreed by stipulation that, as of July 22, 1998, more than 5000 asbestos-related lawsuits were pending against Treadwell. (Stip-¶ 2) Citing this agreement, U.S. Fire states that it "has not confirmed that any additional Asbestos-Related Claims have been asserted against Treadwell.” (U.S. Fire Local Rule 56.1 Statement ¶ 7) Because U.S. Fire has not produced " 'specific facts indicating’ that a genuine factual issue exists,” however, I have accepted Treadwell’s figure for the purposes of these motions.
Scotto v. Almenas,
. To be precise again, Treadwell did not purchase any insurance directly from CIGNA. Instead, CIGNA assumed coverage responsibility as a successor to several other insurance carriers. (Treadwell Local Rule 56.1 Statement ¶ 33)
. To be precise, Treadwell has been unable to identify any insurance coverage prior to 1967.
. The allocation established in the Interim Agreement corresponds only roughly to the primary insurers’ respective proportions of time on the risk between January 1, 1967 and July 1, 1986. Calculated based on the number of days that each insurer provided coverage, CIGNA, AMLIC and Travelers were on the risk 69.1%, 15.4% and 15.5%, respectively, of the so-called Coverage Block.
. “1996 Compl." refers to Treadwell's initial Third-Party Complaint, attached as Exhibit V to the Affidavit of Vincent E. Reilly.
. In addition to allocating responsibility for prospective costs, the Settlement Agreement provides for some reimbursement by USF & G and CU to CIGNA and Travelers for payments made by the latter prior to January 26, 1996, presumably pursuant to the Interim Agreement. (Agrmt. at 8-10, 14-16)
. It may be recalled that CIGNA, Travelers and AMLIC were on the risk 69.1%, 15.5% ■and 15.4%, respectively, of the Coverage Block. See supra note 6.
. Citing a stipulation between the parties that, as of December 31, 1997, Treadwell had paid or promised an aggregate of approximately $850,000 in indemnity payments (StipA 10), U.S. Fire states that it “has not confirmed that any additional payments have been made by Treadwell.” (U.S. Fire’s Local Rule 56.1 Statement ¶ 24) Again, because U.S. Fire has not produced specific facts indicating that a genuine issue exists, I have accepted Treadwell's figure for the purposes of these motions.
See Scotto,
. Under New York law, which the parties agree applies here (StipJ 13), an excess insurer is not required to drop down to provide coverage merely because the underlying primary insurer is insolvent.
See Zeig v. Massachusetts Bonding & Ins. Co.,
.By stipulation so ordered August 26, 1998 — the same day as the aforementioned Stipulation of Material Facts Not in Dispute for Purpose of Summary Judgment Motions— U.S. Fire abandoned the argument that it is not obligated to indemnify or defend until Treadwell has exhausted all of its primary insurance. (See also Treadwell Local Rule 56.1 Statement ¶ 60; 9/16/98 Johnson Aff. ¶ 18) U.S. Fire has not raised the pollution exclusion clause argument. Therefore, I have deemed that argument abandoned.
. I assume arguendo that judicial estoppel applies where the alleged prior inconsistent position was advanced either by a party or, as in this case, by its privy.
. To the extent Treadwell’s argument might be premised on North River’s failure to advocate the proration-to-the-insured approach specifically, it is without merit also. In Mad-sen & Howell, the plaintiff was insured for the entire relevant period. (See 9/17/98 War-shauer Aff. Ex. K at 19) Thus, North River’s silence with respect to the proration-to-the-insured approach is without significance.
. Treadwell appeals also to a common law doctrine called "mend the hold,” so named for a “nineteenth-century wrestling term, meaning to get a better grip (hold) on your opponent.”
Harbor Ins. Co. v. Continental Bank Corp.,
The doctrine’s reach, however, is "uncertain.”
Harbor Ins.,
. The crucial point, not recognized by Tread-well, is that the two issues — whether to allocate among all potentially liable parties
in the first instance
and whether or not to prorate to the insured based on uninsured periods — are analytically distinct.
See Keene,
. The parties spend many pages discussing the effects of the Second Circuit’s decision in
Stonewall
on the allocation issue generally. The allocation issue, however, was not presented to, or decided by, the
Stonewall
Court.
See Stonewall,
The New York Court of Appeals has not yet considered the allocation issue directly. The closest it came to doing so was in
Continental Casualty Co. v. Rapid-American Corp.,
. The policy language in this case (“all sums”) is slightly different from the policy language in
Prudential Lines
("any loss”). This difference, however, is immaterial for present purposes.
Cf. Prudential Lines,
. Strictly speaking, because the
Stonewall
Court did not consider which approach to allocation was warranted, this statement is dictum with respect to the present issue, but it is the kind of dictum that warrants "considerable weight.”
United States
v.
Bell,
. To the extent that these arguments were adopted or rejected in opinions cited by the
Prudential Lines
Court, it might be argued that the Second Circuit implicitly rejected them. Nevertheless, I decline to read into the Court's opinion what is not actually there.

United States,

. Indeed, the speakers themselves rarely professed to offer more than their own individual opinions. For example, one of the documents on which Treadwell relies, the minutes of a September 1964 meeting of the Joint Forms Committee of the National Bureau of Casualty Underwriters and the Mutual Insurance Rating Bureau, reads in relevant part:
Mr. Schoen [of Hartford Accident & Indemnity Company] said that as a fundamental principle we want to cover ... everything flowing from an injurious exposure during the policy period. Mr. Schmalz [of Liberty Mutual Insurance Company] said his understanding was the same, though .it was not the approach he would choose. He thought Mr. Katz [of Aetna Casualty & Surety Company] believed that as to a protracted exposure, the policy in effect at the time the injury became manifest should pay and there should not be proration. Mr. Katz said he did not completely agree with Mr. Schmalz's remarks, and went on to explain that prorating cannot be effectuated between the insurer and the claimant. Between two insurers, of course, they would prorate....
(9/17/98 Warshauer Aff. Ex. C at 11)
. Treadwell invokes also the "reasonable expectations doctrine,” which holds that "if an ambiguity arises that cannot be resolved by examining the parties' intentions, then the ambiguous language should be construed in accordance with the reasonable expectations of the insured when he entered into the contract.”
Haber,
Even if Treadwell had invoked die reasonable expectations doctrine with respect to the issue in dispute, that would not have changed the result. "Assessing the objectively reasonable expectations of a policyholder in this context of long-tail injuries is ... very difficult,”
Owens-Illinois,
. It may be recalled that USF & G and CU agreed to contribute toward Treadwell’s 15.2% share in connection with claims arising from the powerhouse sites for which they provided coverage. These contributions are immaterial for present purposes.
. Interestingly—and significantly, as may be seen later in this opinion, see infra note 26— neither Treadwell nor U.S. Fire questions the allocation of CIGNA’s and Travelers's shares to those insurers’ respective policy periods. Notwithstanding this silence, if the AMLIC Payment should not be allocated entirely to the AMLIC policy period, it follows that CIG-NA’s and Travelers’s payments should not be allocated entirely to their policy periods either.
. By settling, C will save the costs of liliga-lion. For the purposes of comparing the ef- *110 feels of one rule versus another, however, such savings are immaterial.
. Indeed, it is notable in this regard that U.S. Fire does not question the allocation of CIGNA’s and Travelers’s shares to those insurers’ respective policy periods. See supra note 24. Because U.S. Fire is an excess insurer for a different policy period, U.S. Fire stands to gain from the fact that these insurers assumed more liability through the Settlement Agreement than they would have been allocated in the absence of settlement.
. Strictly speaking, the AMLIC Agreement did not limit the AMLIC Payment to the 1970-1972 period. Rather, the payment was made in exchange for a general release from liability under “any and all insurance policies which may have been issued by [AMLIC] to Treadwell, known or unknown(Slip. Ex. E ¶ 2 (emphasis added)) Nevertheless, there is no evidence in the record that AMLIC con-traded to cover any period other than 1970 through 1972. Accordingly, the AMLIC Payment should be allocated in its entirety to those years.
. Each of the parties relies as well on Judge Martin's decision in
