FEINMAN, J.:
*1188**209The narrow issue before us pertains to the scope of our prior ruling in ***512Excess Insurance Co. Ltd. v. Factory Mutual Insurance Co., 3 N.Y.3d 577, 789 N.Y.S.2d 461, 822 N.E.2d 768 (2004). Pursuant to Rule 500.27 of this Court, the United States Court of Appeals for the Second Circuit has certified the following question to us:
"Does the decision of the New York Court of Appeals in [ Excess ] impose either a rule of construction, or a strong presumption, that a per occurrence liability cap in a reinsurance contract limits the total reinsurance available under the contract to the amount of the cap regardless of whether the underlying policy is understood to cover expenses such as, for instance, defense costs?"
( Global Reinsurance Corporation of America v. Century Indemnity Company, 843 F.3d 120, 128 [2d Cir.2016] ).1 We now answer the certified question in the negative. Under New York law generally, and in Excess in particular, there is neither a rule of construction nor a presumption that a per occurrence liability limitation in a reinsurance contract caps all obligations of the reinsurer, such as payments made to reimburse the reinsured's defense costs.
I.
Reinsurance is the insurance of one insurer by another (see Matter of Union Indem. Ins. Co. of N.Y., 89 N.Y.2d 94, 105-106, 651 N.Y.S.2d 383, 674 N.E.2d 313 [1996] ). "When entering into a reinsurance contract, an insurance company agrees to pay a particular premium to a reinsurer in return for reimbursement of a portion of its potential financial exposure under certain direct insurance policies it has issued to its customers" ( Travelers Cas. & Sur. Co. v. Certain Underwriters at Lloyd's of London, 96 N.Y.2d 583, 587, 734 N.Y.S.2d 531, 760 N.E.2d 319 [2001] ). "Through this indemnity relationship, the reinsured seeks to 'cede' or spread its risk of loss among one or more reinsurers" ( id. ). Through *1189this process, reinsurance **210permits the cedent insurer to "minimize its exposure to catastrophic ***513loss," "reduce the amount of the legally required reserves held for the protection of policyholders," and "increase [its] ability to underwrite other policies or make other investments" ( Matter of Midland Ins. Co., 79 N.Y.2d 253, 258, 582 N.Y.S.2d 58, 590 N.E.2d 1186 [1992] ).
There are two types of reinsurance: treaty and facultative. Under a reinsurance treaty, the cedent transfers to the reinsurer its risk under an entire line of business spanning multiple insurance policies (see Travelers, 96 N.Y.2d at 587-588, 734 N.Y.S.2d 531, 760 N.E.2d 319 ; Sumitomo Marine & Fire Ins. Co., Ltd.-U.S. Branch v. Cologne Reinsurance Co. of America, 75 N.Y.2d 295, 301, 552 N.Y.S.2d 891, 552 N.E.2d 139 [1990] ). By contrast, in facultative reinsurance, the reinsurer agrees to indemnify the cedent for all or a portion of the cedent's risk under a single policy in the event of loss (see 1A Couch on Ins. § 9:3 [3d ed.2016] ; Travelers, 96 N.Y.2d at 587, 734 N.Y.S.2d 531, 760 N.E.2d 319 ). In other words, "[f]acultative reinsurance is policy-specific" ( Travelers, 96 N.Y.2d at 587, 734 N.Y.S.2d 531, 760 N.E.2d 319 ). For purposes of this certified question, we are concerned only with facultative reinsurance.2
The coverage provided under a facultative reinsurance contract is "memorialized in a certificate" (Barry R. Ostrager & May Kay Vyskocil, Modern Reinsurance Law and Practice § 1:03 [3d ed.2014]; accord William Hoffman, Facultative Reinsurance Contract Formation, Documentation and Integration, 38 Tort Trial & Ins Prac L J 763, 809 [Spring 2003] ["By a certificate, the reinsurer attests that the facultative reinsurance placement is complete and the contract in effect"] ). These certificates are usually "standard forms" ( North River Ins. Co. v. CIGNA Reinsurance Co., 52 F.3d 1194, 1199 [3d Cir.1995] ), "short and concise, using terms of art rather than lengthy, legalistic explications to define the obligations of the parties" (Ostrager & Vyskocil, § 2:02; see Sumitomo, 75 N.Y.2d at 302, 552 N.Y.S.2d 891, 552 N.E.2d 139 ).
Typically, the facultative reinsurer is obligated to indemnify the cedent up to a stated upper limit (see Travelers, 96 N.Y.2d at 588, 734 N.Y.S.2d 531, 760 N.E.2d 319 ). For example, one of the certificates relevant to the underlying dispute, which the parties refer to as "Certificate X," reads:
"Item 1-Type of Insurance
Blanket General Liability, excluding Automobile Liability as original.
***514Item 2-Policy Limits and Application
$1,000,000. each occurrence as original.
Item 3-[Cedent] Company Retention
The first $500,000. of liability as shown in Item # 2 above.
Item 4-Reinsurance Accepted
$250,000. part of $500,000. each occurrence as original excess of the [cedent] Company's retention as shown in Item # 3 above.
Item 5-Basis
Excess of Loss"
( Global Reinsurance, 843 F.3d at 123 ). Certificate X reinsures an underlying insurance policy of $1 million per occurrence, with the cedent retaining the first $500,000 *1190**211of such liability, and the reinsurer assuming up to $250,000 in excess thereof.
An underlying third-party liability insurance policy will often require the insurer to either pay the insured's costs in defending covered claims, or to provide legal counsel and defend the claim itself (see e.g. Seaboard Sur. Co. v. Gillette Co., 64 N.Y.2d 304, 309-310, 486 N.Y.S.2d 873, 476 N.E.2d 272 [1984] ). These expenses are distinct from indemnity payments for actual losses (see id. at 310, 486 N.Y.S.2d 873, 476 N.E.2d 272 ["Though policy coverage is often denominated as 'liability insurance,' where the insurer has made promises to defend 'it is clear that (the coverage) is, in fact, 'litigation insurance' as well"], quoting International Paper Co. v. Continental Cas. Co., 35 N.Y.2d 322, 326, 361 N.Y.S.2d 873, 320 N.E.2d 619 [1974] ).
One recurring issue in reinsurance disputes is whether these defense costs, insofar as they are reinsured by a facultative reinsurance policy, count towards the limit in the reinsurance accepted clause ($250,000 in the example above). Here, Global averred that, as of the filing of its motion for summary judgment, Century billed it $327,149 under Certificate X, consisting of $82,627 in loss and $244,522 in expense. Global argued that, under the reinsurance accepted clause, its obligation to Century for both loss and expense payments under Certificate X is capped at $250,000 (see Global Reinsurance, 843 F.3d at 123 ). Century argued that this $250,000 limit applied only to losses and that Global must also pay all expenses, even if losses and expenses combined would exceed $250,000 ( id. ).
This brings us to the question certified by the Second Circuit: whether our 2004 decision in Excess, 3 N.Y.3d 577, 789 N.Y.S.2d 461, 822 N.E.2d 768 ) imposed "either ***515a rule of construction, or a strong presumption, that a per occurrence liability cap in a reinsurance contract limits the total reinsurance available under the contract, to the amount of the cap regardless of whether the underlying policy is understood to cover expenses such as, for instance, defense costs" ( Global Reinsurance, 843 F.3d at 128 ). As the Second Circuit noted:
"If Excess imposes a clear rule (or a presumption) with respect to these reinsurance policies, the rule would guide our interpretation of this and substantially similar policies. If, on the other hand, the standard rules of contract interpretation apply, we would construe each reinsurance policy solely in light of its language and, to the extent helpful, specific context"
( id. ). We now turn to that decision.
II.
Our opinion in Excess addressed whether a reinsurer's obligation to pay loss adjustment expenses3 arising from a "follow-the-settlements" clause was subject to the stated indemnification limit in the reinsurance policy. Factory Mutual Insurance Company (Factory) issued a property insurance policy to Bull Data Systems Inc. (Bull Data), covering the risk of loss or damage to Bull Data's personal computer inventory (see Excess, 3 N.Y.3d at 579, 789 N.Y.S.2d 461, 822 N.E.2d 768 ). Factory, in turn, reinsured the Bull Data policy with various reinsurers, including the respondents in that case (see id. at 579-80, 789 N.Y.S.2d 461, 822 N.E.2d 768 ). The respondents issued a facultative reinsurance *1191**212certificates to Factory that read, in relevant part:
"INTEREST: Goods and/or merchandise incidental to the Assured's business consisting principally of personal computers and/or as original.
"LIMIT: US$ 7,000,000 any one occurrence p/o US$ 13,500,000 any one occurrence excess of US$ 25,000,000 any one occurrence
"CONDITIONS: As original and subject to the same valuation, clauses and conditions as contained in the original policy or policies but only to cover risks ***516of All Risks of Physical Loss or Damage but excluding Inventory Shortage. Including Strikes, Riots, Civil Commotions and Malicious Damage risks if and as original. Premium payable as original. Reinsurers agree to follow the settlements of the Reassured in all respects and to bear their proportion of any expenses incurred, whether legal or otherwise, in the investigation and defence of any claim hereunder. Service of Suit Clause (U.S.A.). Insolvency Clause"
( id. at 580, 789 N.Y.S.2d 461, 822 N.E.2d 768 ). A fire destroyed the warehouse where Bull Data's inventory was stored and, suspecting arson, Factory disputed coverage (see id. at 580-81, 789 N.Y.S.2d 461, 822 N.E.2d 768 ). Though Factory ultimately settled the claim, it incurred approximately $35 million in loss adjustment expenses in the litigation against Bull Data (see id. ). Factory then sought $12 million from the respondents, representing $7 million for the Bull Data settlement and an additional $5 million representing the reinsurers' proportional share of loss adjustment expenses (see id. ). Factory argued that the reinsurers' undertaking to bear their proportion of expenses pursuant to the follow-the-settlements clause was "separate and apart from the indemnification cap on the policy," while the reinsurers countered that their aggregate liability, expenses and all, was capped at $7 million ( id. at 582-83, 789 N.Y.S.2d 461, 822 N.E.2d 768 ).
We held that the reinsurers were entitled to summary judgment on the issue. "Once the reinsurers have paid the maximum amount stated in the policy, they have no further obligation to pay Factory Mutual any costs related to loss adjustment expenses" ( id. at 583, 789 N.Y.S.2d 461, 822 N.E.2d 768 ). Having interpreted the "LIMIT" clause to impose an expense-inclusive $7 million cap, we then rejected Factory's contention that the reinsurers' obligation to indemnify it for loss adjustment expenses could supersede that clause (see id. ).
Although Excess did not say that third-party defense costs under any facultative reinsurance contract are unambiguously or presumptively capped by the liability limits in the certificate, some courts have nonetheless read our decision that way (see Utica Mut. Ins. Co. v. Munich Reinsurance America, Inc., 594 Fed. Appx. 700, 704 [2d Cir.2014] [summary order] ["(T)he Court of Appeals arguably ... suggested that a limit of liability, standing alone, is presumptively expense-inclusive because it serves to cap a reinsurer's total exposure (for losses and expenses) at a specific, negotiated amount"] [emphasis omitted];
***517Century Indemnity Company v. OneBeacon Insurance Company, 2017 PA Super 328, 173 A.3d 784, 797 [Pa.Super.2017] [describing "the presumption created by the Excess Court that defense costs are capped by the liability limits unless they are explicitly excluded elsewhere in the certificate"]; Utica Mut. Ins. Co. v. Clearwater Ins. Co., 2014 WL 6610915, at *3 [N.D.N.Y. Nov. 20, 2014] [stating that, under Excess,"a facultative reinsurance certificate's stated limit provides an overall cap on the reinsurer's liability unless it *1192**213expressly states that expenses are excluded from the certificate's limit"], reconsideration denied 2015 WL 4496374 [N.D.N.Y. Jul. 23, 2015] ). We now dispel any intimation that Excess established such a rule.
"It is basic that principles of law 'are not established by what was said, but by what was decided, and what was said is not evidence of what was decided, unless it relates directly to the question presented for decision' " ( Knight-Ridder Broadcasting, Inc. v. Greenberg, 70 N.Y.2d 151, 160 n. 6, 518 N.Y.S.2d 595, 511 N.E.2d 1116 [1987], quoting People ex rel. Metropolitan St. Ry. Co. v. State Bd. of Tax Commrs., 174 N.Y. 417, 447, 67 N.E. 69 [1903] ; accord Art Masters Associates, Ltd. v. United Parcel Service, 77 N.Y.2d 200, 208 n. 6, 566 N.Y.S.2d 184, 567 N.E.2d 226 [1990 ). Accordingly, the Court's holding comprises only those "statements of law which address issues which were presented to the [Court] for determination" ( Village of Kiryas Joel v. County of Orange, 144 A.D.3d 895, 900, 43 N.Y.S.3d 51 [2d Dept.2016] ).
The Excess Court was simply not faced with the question presently before the Second Circuit: whether there is a blanket "presumption" or "rule of construction" that a limitation-on-liability clause applies to all payments by a reinsurer whatsoever. The only issue before the Court was whether that certificate's phrase "LIMIT: US$ 7,000,000," in context, established that the reinsurers' aggregate liability for both settlement costs and loss adjustment expenses was capped at $7 million. Each party seized on unique turns of phrase in the certificate to argue that they were entitled to judgment as a matter of law. Critically, we did not read the limit clause in isolation, but in light of the entire agreement as an integrated whole, "giv[ing] meaning to every sentence, clause and word" thereof ( Travelers, 96 N.Y.2d at 594, 734 N.Y.S.2d 531, 760 N.E.2d 319, citing Northville Indus. Corp. v. National Union Fire Ins. Co., 89 N.Y.2d 621, 632-633, 657 N.Y.S.2d 564, 679 N.E.2d 1044 [1997] ). This is precisely what we have done in other reinsurance cases, both before Excess and since (see ***518United States Fid. & Guar. Co. v. American Re-Ins. Co., 20 N.Y.3d 407, 419-420, 962 N.Y.S.2d 566, 985 N.E.2d 876 [2013] ; Union Carbide Corp. v. Affiliated FM Ins. Co., 16 N.Y.3d 419, 424-425, 922 N.Y.S.2d 220, 947 N.E.2d 111 [2011] ; Travelers, 96 N.Y.2d at 594, 734 N.Y.S.2d 531, 760 N.E.2d 319 ).
In addition, the loss adjustment expenses were incurred in litigation between the insurer and its policyholder; they were not costs (such as third-party defense costs) that the insurer was obligated to pay under the terms of the underlying policy itself. Whether a similar (or even identical) limitation clause would apply to third-party defense costs, in a certificate reinsuring a liability insurance policy, was never at issue. Consequently, the Excess Court did not pass on whether a follow-form clause such as the one in that case, "subject[ing]" the reinsurance "to the same valuation, clauses and conditions as contained in the original policy," would require the reinsurers to cover third-party defense costs in excess of such a limit.
III.
We hold definitively that Excess did not supersede the "standard rules of contract interpretation" ( Global Reinsurance, 843 F.3d at 128 ) otherwise applicable to facultative reinsurance contracts. "Stare decisis does not spring full-grown from a 'precedent' but from precedents which reflect principle and doctrine rationally evolved" ( People v. Hobson, 39 N.Y.2d 479, 488, 384 N.Y.S.2d 419, 348 N.E.2d 894 [1976] ). We therefore read Excess in harmony with the traditional rules of contract *1193**214interpretation reiterated numerous times by this Court.
Reinsurance contracts are governed by the same principles that govern contracts generally (see Unigard Sec. Ins. Co., Inc. v. North River Ins. Co., 79 N.Y.2d 576, 584, 584 N.Y.S.2d 290, 594 N.E.2d 571 [1992] [in reinsurance dispute, "there is no sound reason to depart" from "general contract law principle(s)"]; British Intern. Ins. Co. Ltd. v. Seguros La Republica, S.A., 342 F.3d 78, 82 [2d Cir.2003] ; Christiania General Ins. Corp. of New York v. Great American Ins. Co., 979 F.2d 268, 274 [2d Cir.1992] ). "Reinsurance, like any other contract, depends upon the intention of the parties, to be gathered from the words used, taking into account, when the meaning is doubtful, the surrounding circumstances" ( London Assur. Corp. v. Thompson, 170 N.Y. 94, 99, 62 N.E. 1066 [1902] ). The agreement should be "read as a whole, and every part will be interpreted with reference to the whole" ( Beal Sav. Bank v. Sommer, 8 N.Y.3d 318, 324-335, 834 N.Y.S.2d 44, 865 N.E.2d 1210 [2007], quoting Matter of Westmoreland Coal Co. v. Entech, Inc., 100 N.Y.2d 352, 358, 763 N.Y.S.2d 525, 794 N.E.2d 667 [2003] ). Particularly where an agreement is "negotiated between sophisticated, counseled business people ***519negotiating at arms length, ... courts should be extremely reluctant to interpret an agreement as impliedly stating something which the parties have neglected to specifically include" ( Vermont Teddy Bear Co. v. 538 Madison Realty Co., 1 N.Y.3d 470, 475, 775 N.Y.S.2d 765, 807 N.E.2d 876 [2004] [citations and internal quotations omitted] ). Courts should be mindful that the certificate, while serving as written confirmation of a contract, might not in and of itself constitute the fully integrated agreement (see Sumitomo, 75 N.Y.2d at 302, 552 N.Y.S.2d 891, 552 N.E.2d 139 ["(I)ssuance ... of a formal certificate of reinsurance" is "technically unnecessary for a binding agreement"]; Union Carbide Corp., 16 N.Y.3d at 425, 922 N.Y.S.2d 220, 947 N.E.2d 111 [where reinsurance policy incorporates underlying policy, the underlying policy is not considered extrinsic evidence] ).
Like any contract, a facultative reinsurance contract "that is complete, clear and unambiguous on its face must be enforced according to the plain meaning of its terms" ( Marin v. Constitution Realty, LLC, 28 N.Y.3d 666, 673, 49 N.Y.S.3d 39, 71 N.E.3d 530 [2017], quoting Greenfield v. Philles Records, 98 N.Y.2d 562, 569, 750 N.Y.S.2d 565, 780 N.E.2d 166 [2002] ). Ambiguity is ascertained by reading the terms of the agreement, not in isolation, but "as a whole" ( Ellington v. EMI Music, Inc., 24 N.Y.3d 239, 244, 997 N.Y.S.2d 339, 21 N.E.3d 1000 [2014] ). If a contract "is reasonably susceptible of only one meaning, a court is not free to alter the contract to reflect its own personal notions of fairness and equity" ( Selective Ins. Co. of America v. County of Rensselaer, 26 N.Y.3d 649, 655, 47 N.E.3d 458 [2016], quoting Greenfield, 98 N.Y.2d at 569-570, 750 N.Y.S.2d 565, 780 N.E.2d 166 ). Rather than "adopting a blanket rule, based on policy concerns," the court must "look to the language of the policy" above all else ( In re Viking Pump, Inc., 27 N.Y.3d 244, 257, 33 N.Y.S.3d 118, 52 N.E.3d 1144 [2016] ). Our cases in the insurance context confirm that even modest variations on the face of a written agreement can alter the meaning of a critical term (see e.g. id. at 258-259, 33 N.Y.S.3d 118, 52 N.E.3d 1144 [distinguishing Consolidated Edison Co. of N.Y. v. Allstate Ins. Co., 98 N.Y.2d 208, 746 N.Y.S.2d 622, 774 N.E.2d 687 (2002) ]; Selective Ins. Co., 26 N.Y.3d at 656 and n. *, 27 N.Y.S.3d 92, 47 N.E.3d 458 [2016] [distinguishing Appalachian Ins. Co. v. General Elec. Co., 8 N.Y.3d 162, 173, 831 N.Y.S.2d 742, 863 N.E.2d 994 (2007) ] ).
*1194**215The foregoing principles do not permit a court to disregard the precise terminology that the parties used and simply assume, based on its own familiar notions of economic efficiency, that any clause bearing the generic marker of a "limitation on liability" or "reinsurance accepted" clause was intended to be cost-inclusive. Therefore, New York law does not impose either a rule, or a presumption, that a limitation on liability clause necessarily caps all obligations owed by a reinsurer, such as defense costs, without regard for the specific language employed therein.
***520IV.
"[I]t is important to emphasize that we are called upon to decide a narrow issue" ( Ehrenfield v. Bin Mahfouz, 9 N.Y.3d 501, 507, 851 N.Y.S.2d 381, 881 N.E.2d 830 [2007] ), namely, whether Excess imposes "either a rule of construction, or a strong presumption, that a per occurrence liability cap in a reinsurance contract limits the total reinsurance available under the contract," including defense costs ( Global Reinsurance, 843 F.3d at 128 ). For the foregoing reasons, we hold that it does not.
Accordingly, the certified question should be answered in the negative.
Following certification of a question by the United States Court of Appeals for the Second Circuit and acceptance of the question by this Court pursuant to section 500.27 of this Court's Rules of Practice, and after hearing argument by counsel for the parties and consideration of the briefs and the record submitted, certified question answered in the negative.
