Lead Opinion
**301The issue here is whether plaintiffs' collective-bargaining agreements (CBAs) with defendant, Macomb County, granted plaintiffs a vested right to lifetime and unalterable retirement healthcare benefits. The trial court held that while plaintiffs are entitled to lifetime healthcare benefits, defendant can make reasonable modifications to those benefits. On appeal, the Court of Appeals held that plaintiffs are entitled to *607lifetime and unalterable healthcare benefits and that such benefits cannot be modified absent plaintiffs' consent. Because we conclude that the CBAs did not grant plaintiffs a vested right to lifetime and unalterable benefits, we reverse the judgment of the Court of Appeals and remand to the Macomb Circuit Court for entry of an order granting summary disposition to defendant consistent with this opinion. **302I. BACKGROUND
This is a class action brought on behalf of approximately 1600 unionized Macomb County employee retirees who worked for defendant under various CBAs dating back to 1989. Plaintiffs claim that in 2009 and 2010 defendant breached these agreements by reducing and altering their healthcare benefits; plaintiffs now seek both monetary damages and injunctive relief. It is undisputed that each CBA contained an express three-year durational provision and that none of the CBAs contained a provision expressly granting a vested right to lifetime and unalterable retirement healthcare benefits. The trial court granted defendant's motion for summary disposition, concluding that while plaintiffs are entitled to lifetime healthcare benefits under the agreements, defendant is permitted to make reasonable modifications to those benefits. The Court of Appeals affirmed in part and reversed in part, concluding that while plaintiffs are entitled to lifetime healthcare benefits, those benefits cannot be modified absent plaintiffs' consent.

**303III. ANALYSIS
It is undisputed that all of the CBAs contain the following provisions or provisions that are "materially similar":
Retirees: The Employer will provide fully paid Blue Cross/Blue Shield Hospital-Medical coverage to the employee and the employee's spouse, after eight (8) years of service with the Employer, for the employee who leaves employment because of retirement and is eligible for and receives benefits under the Macomb County Employees' Retirement Ordinance ....
* * *
Coverage shall be limited to the current spouse of the retiree, at the time of retirement, provided such employee shall retire on or after January 1, 1974. Coverage for the eligible spouse will terminate upon the death of the retiree unless the retiree elects to exercise a retirement option whereby the eligible current spouse receives applicable retirement benefits following the death of the retiree.
Coverage shall be limited to Blue Cross/Blue Shield MVF1 Master Medical with ML Rider, or its substantial equivalence.
*608* * *
Retired employees and/or their current spouse, upon reaching age 65, shall apply if eligible, and participate in the Medicare Program at their expense as required by the Federal Insurance Contribution Act, a part of the Social Security Program, at which time the Employer's obligation shall be only to provide "over 65 supplemental" hospital-medical benefit coverage. Failure to participate **304in the aforementioned Medicare Program, shall be cause for termination of Employer paid coverage of applicable hospital-medical benefits, as outlined herein for employees who retire and/or their current spouse.
Employees who retire under the provisions of the Macomb County Employees' Retirement Ordinance, and/or their current spouse, who subsequently are gainfully employed, shall not be eligible for hospital-medical benefits, during such period of gainful employment ....
* * *
The parties acknowledge that during the negotiations which resulted in this Agreement each had the unlimited right and opportunity to make demands and proposals with respect to all subjects of collective bargaining and that all agreements and understandings, expressed, implied, written or oral, are set forth in this Agreement. This Agreement expresses the complete understanding of the Parties on the subject of wages, working conditions, hours of work, benefits and conditions of employment.
* * *
This Agreement shall continue in full force and effect until December 31, 2007. [Paragraph lettering omitted.]
The issue is whether the CBAs granted plaintiffs vested rights to lifetime and unalterable retirement healthcare benefits. In Int'l Union, United Auto., Aerospace & Agricultural Implement Workers of America (UAW) v. Yard-Man, Inc. ,
characterized [ Yard-Man and its progeny] as "placing a thumb on the scale in favor of vested retiree benefits in all collective-bargaining agreements." Those decisions, the Supreme Court explained, "distort the text of [a collective-bargaining] agreement and conflict with the principle of contract law that the written agreement is presumed to encompass the whole agreement of the parties." Indeed, basic principles of contract interpretation instruct that "courts should not construe ambiguous writings to create lifetime promises" and, absent a contrary intent, that "contractual obligations will cease, in the ordinary course, upon termination of the bargaining agreement." For "when a contract is silent as to the duration of retiree benefits, a court may not infer that the parties intended those benefits to vest for life." [ Arbuckle ,499 Mich. at 540 ,885 N.W.2d 232 , quoting Tackett , 574 U.S. at ----,135 S.Ct. at 935-937 (quotation marks omitted; second alteration in Arbuckle ).][2 ]
*609Tackett specifically rejected many of the same arguments raised by plaintiffs in the instant case. For example, Tackett rejected Yard-Man 's presumption that a general durational clause, which specifies when a contract will expire, states nothing about the vesting of retiree benefits.
**306Tackett , 574 U.S. at ----,
Yard-Man ,
Post- Tackett , "the Sixth Circuit [in Reese v. CNH Indus. N.V. ,
**308Tellingly, no other Court of Appeals would find ambiguity in these circumstances. When a collective-bargaining agreement is merely silent on the question of vesting, other courts would conclude that it does not vest benefits for life. Similarly, when an agreement does not specify a duration for health care benefits in particular, other courts would simply apply the general durational clause. And other courts would not find ambiguity from the tying of retiree benefits to pensioner status....
Shorn of Yard-Man inferences, this case is straightforward. The 1998 agreement contained a general durational clause that applied to all benefits, unless the agreement specified otherwise. No provision specified that the health care benefits were subject to a different durational clause.... If the parties meant to vest health care benefits for life, they easily could have said so in the text. But they did not. And they specified that their agreement "dispose[d] of any and all bargaining issues" between them. Thus, the only reasonable interpretation of the 1998 agreement is that the health care benefits expired when the collective-bargaining agreement expired in May 2004. "When the intent of the parties is unambiguously expressed in the contract, that expression controls, and the court's inquiry should proceed no further." [Id. at ----,138 S.Ct. at 766 (citations omitted; alteration in Reese ).][6 ]
The Court of Appeals in the instant case did exactly what the Sixth Circuit did in Reese , i.e., it relied on the Yard-Man inferences to find the CBAs ambiguous and then resorted to extrinsic evidence to find in favor of **309lifetime healthcare benefits.
"A contractual term is ambiguous on its face only if it is equally susceptible to more than a single meaning." Barton-Spencer v. Farm Bureau Life Ins. Co. of Mich. ,
**312"[C]ourts cannot simply ignore portions of a contract ... in order to declare an ambiguity." Klapp ,
"A fundamental tenet of our jurisprudence is that unambiguous contracts are not open to judicial construction and must be enforced as written. " Rory v. Continental Ins. Co. ,
*613Wilkie v. Auto-Owners Ins. Co. ,
**313These contract principles apply to CBAs just as they do with regard to any other contract. As this Court has explained:
The foundational principle of our contract jurisprudence is that parties must be able to rely on their agreements. This principle applies no less strongly to collective bargaining agreements: when parties to a collective bargaining agreement bargain about a subject and memorialize the results of their negotiation in a collective bargaining agreement, they create a set of enforceable rules-a new code of conduct for themselves-on that subject. A party to the collective bargaining agreement has a right to rely on the agreement as the statement of its obligations on any topic covered by the agreement. [ Macomb Co. v. AFSCME Council 25 ,494 Mich. 65 , 80,833 N.W.2d 225 (2013) (quotation marks and citations omitted).]
In Harper Woods Retirees Ass'n v. City of Harper Woods ,
Post- Tackett , the Sixth Circuit addressed this same issue in Gallo v. Moen Inc. ,
First and foremost , nothing in this or any of the other CBAs says that Moen committed to provide unalterable healthcare benefits to retirees and their spouses for life. That is what matters, and that is where the plaintiffs fall short. Tackett directs us to apply ordinary contract principles and not to tilt the inquiry in favor of vesting-a frame of reference that prompts two questions. What *614is the contract right that the plaintiffs seek to vindicate? And does the contract contain that right? The plaintiffs claim a right to healthcare benefits for life. But the contracts never make that commitment. Yes, Moen offered retirees healthcare benefits. And yes Moen, like many employers, may have wished that business conditions and stable healthcare costs (hope springs eternal) would permit it to provide similar healthcare benefits to retirees throughout retirement. But the question is whether the two parties signed a contract to that effect. Nothing of the sort appears in the collective bargaining agreements.
Second , not only do the CBAs fail to say that Moen committed to provide unalterable healthcare benefits for life to retirees, everything they say about the topic was contained in a three-year agreement. If we do not expect to find "elephants in mouseholes" in construing statutes, we should not expect to find lifetime commitments in time-limited **315agreements. Each of the CBAs made commitments for approximately three-year terms-well short of commitments for life. Present in each CBA, the general durational clause supplied a concrete date of expiration after which either party could terminate the agreement. When a specific provision of the CBA does not include an end date, we refer to the general durational clause to determine that provision's termination. Absent a longer time limit in the context of a specific provision, the general durational clause supplies a final phrase to every term in the CBA: "until this agreement ends." Reading the healthcare provisions in conjunction with the general durational clause gives meaning to the phrases "[c]ontinued," "will be provided," "will be covered," and the like. These terms guarantee benefits until the agreement expires, nothing more. [ Id. at 269 (citations omitted).]
The Gallo analysis applies equally to the instant case. It is undisputed that none of the CBAs at issue specifies that defendant committed itself to provide lifetime and unalterable healthcare benefits. It is also undisputed that the CBAs contain three-year durational provisions. Therefore, the CBAs guarantee benefits only until the agreements expire and no longer. In other words, because the CBAs do not specify an alternative ending date for healthcare benefits, their general durational clauses control.
The trial court here found that the CBAs are not ambiguous and that "[d]efendant did not promise or otherwise obligate itself under the clear language to provide a certain duration or level of retiree healthcare coverage beyond the term of each CBA." Indeed, it held that "plaintiffs have not pointed to any specific CBA language explicitly conferring lifetime or unalterable healthcare benefits on retirees." Nevertheless, the court held that plaintiffs are entitled to lifetime healthcare benefits because "plaintiffs have proffered unrefuted evidence that defendant has acknowledged that retiree **316healthcare coverage is a lifetime benefit." Finally, the trial court held that these lifetime benefits are not unalterable because "plaintiffs have not established [that] defendant has unequivocally acknowledged that it is obligated to provide[ ] unalterable retiree healthcare coverage." The court concluded that while "retirees have lifetime healthcare benefits," defendant "may reasonably modify the scope and level of benefits from those that existed when the retirees retired."
While the trial court correctly held that the CBAs are not ambiguous and that they do not provide for unalterable lifetime healthcare benefits, it nonetheless relied on extrinsic evidence to conclude *615that plaintiffs are entitled to lifetime benefits that can be reasonably modified. However, since the CBAs are not ambiguous, the trial court should not have considered extrinsic evidence because the "parol evidence rule ... prohibits the use of extrinsic evidence to interpret unambiguous language within a document." Shay v. Aldrich ,
Although the Court of Appeals recognized that the "CBAs do not expressly state whether the benefits were promised indefinitely or only for the duration of the CBA," it concluded that "other contract language creates a latent ambiguity regarding whether the healthcare benefits are vested." Kendzierski ,
Respectfully, the Court of Appeals erred by finding a latent ambiguity. "A latent ambiguity ... is one that does not readily appear in the language of a document, but instead arises from a collateral matter when the document's terms are applied or executed." Shay ,
The Court of Appeals rested its ambiguity conclusion on three provisions of the CBAs: (a) "the CBAs contain a 'survivor' option permitting continuation of a surviving spouse's healthcare coverage following the death of the retiree," (b) "the CBAs provide that the agreement may be terminated if the retiree fails to enroll in Medicare at age 65," and (c) "the CBAs provide that healthcare coverage is suspended *616while the retiree has coverage through another employer but then states that coverage through the CBA recommences once the coverage through the other employer ends." Kendzierski ,
We do not agree that these provisions render the CBAs ambiguous. The first provision relied on by the Court of the Appeals-the surviving-spouse provision-reads:
Coverage shall be limited to the current spouse of the retiree, at the time of retirement, provided such employee shall retire on or after January 1, 1974. Coverage for the eligible spouse will terminate upon the death of the retiree unless the retiree elects to exercise a retirement option whereby the eligible current spouse receives applicable retirement benefits following the death of the retiree.
The Court of Appeals concluded that because the provision "contemplates that coverage will continue until, and even after, the death of the retiree," it "indicates that the parties intended that the healthcare coverage would last beyond the three-year term of the individual CBAs." Kendzierski ,
The United States Court of Appeals for the Seventh Circuit, in considering a similar surviving-spouse provision, stated as follows:
The retirees argue that the [collective-bargaining insurance agreement] is implicitly extended beyond its three-year term by a clause that provides benefits for surviving spouses until their death or remarriage. This provision, however, refers to the eligibility of individuals to receive benefits under the agreement, not to the duration of the agreement. Surviving spouses were eligible to receive benefits only so long as the [collective-bargaining insurance agreement] was in place. [ Cherry v. Auburn Gear, Inc. ,441 F.3d 476 , 483 (C.A. 7, 2006).][13 ]
Similarly, the surviving-spouse provision of the CBAs in this case governs the eligibility of the spouse upon **320the death of the retiree; it does not set the duration of either the retiree's or the spouse's benefits. Therefore, the provision does not evidence an intention that the benefits continue beyond the term provided in the *617durational clause of the CBAs.
The Court of Appeals' reliance on the provision requiring enrollment in Medicare at age 65 is also unavailing. That provision states:
Retired employees and/or their current spouse, upon reaching age 65, shall apply if eligible, and participate in the Medicare Program ... at which time the Employer's obligation shall be only to provide "over 65 supplemental" hospital-medical benefit coverage. Failure to participate in the aforementioned Medicare Program, shall be cause for termination of Employer paid coverage of applicable hospital-medical benefits, as outlined herein for employees who retire and/or their current spouse.
The Court of Appeals reasoned that "[t]his provision again contemplates that the coverage outlasts the three-year period of the CBA given that a retiree may retire years before turning 65." Kendzierski ,
Finally, we also do not find that the subsequent-employment provision creates an ambiguity as to whether the parties *618intended that retiree benefits would vest. It states:
**322Employees who retire under the provisions of the Macomb County Employees' Retirement Ordinance, and/or their current spouse, who subsequently are gainfully employed, shall not be eligible for hospital-medical benefits, during such period of gainful employment ....
The Court of Appeals identified in this provision an implication "that the retirees will receive healthcare benefits far beyond the three-year term of the CBAs." Kendzierski ,
Contrary to the Court of Appeals' analysis, none of these provisions gives rise to an ambiguity.
IV. CONCLUSION
Because we conclude that the CBAs did not grant plaintiffs a vested right to lifetime and unalterable retirement healthcare benefits, in lieu of granting leave to appeal, we reverse the judgment of the Court **327of Appeals and remand to the Macomb Circuit Court for entry of an order granting summary disposition to defendant consistent with this opinion.
Zahra, Viviano, and Clement, JJ., concurred with Markman, J.
At oral argument before this Court, defense counsel indicated that all of the pertinent CBAs contain "similar provisions" and that there is no "dispute as to the nature of the provisions in this case"; plaintiffs' counsel also stated that the CBAs are "materially similar."
In Arbuckle , 499 Mich. at 525,
Yard-Man ,
Tackett also rejected the argument that retiree healthcare benefits constitute a form of "deferred compensation." Tackett , 574 U.S. at ----,
See Litton Fin. Printing Div. v. Nat'l Labor Relations Bd. ,
In Int'l Union, United Auto., Aerospace & Agricultural Implement Workers of America v. Kelsey-Hayes Co. ,
The dissent distinguishes Tackett on the ground that Tackett "did not address whether there was ambiguity in the parties' CBA ...." However, Reese , 583 U.S. at ----,
The dissent also asserts that Reese is distinguishable because the "CBA [in Reese ] differed from those here in one important respect that mattered to the Court's analysis: it included language that specifically tied the promise of retiree healthcare to the agreement's general durational clause." We respectfully disagree. In Reese , a group benefit plan was incorporated into the CBA by language providing that the group benefit plan " 'will run concurrently with this Agreement and is hereby made a part of this Agreement.' " Reese v. CNH Indus. N.V. ,
Indeed, Tackett , 574 U.S. at ----,
The parties do not dispute that, unlike in Arbuckle , 499 Mich. at 532-536,
See Mayor of the City of Lansing v. Pub. Serv. Comm. ,
The dissent appears to be relying on the rule of reasonable expectations to discern an ambiguity in the CBAs when it states in several places that plaintiffs "believe[d]," "underst[ood]," and "thought" that they would have healthcare benefits for the rest of their lives. However, what plaintiffs believed, understood, and thought about their healthcare benefits is only relevant to the extent that it is supported by the actual language of the pertinent CBAs. Wilkie ,
This Court approvingly cited Gallo in Arbuckle , 499 Mich. at 540 n. 56,
Both defendant's counsel and plaintiffs' counsel acknowledged at oral argument before this Court that the Court of Appeals misused the term "latent ambiguity." The classic example of a latent ambiguity is found in Raffles v. Wichelhaus , 2 Hurl & C. 906; 159 Eng. Rep. 375 (1864), in which the parties contracted for a shipment "to arrive ex Peerless" from Bombay, but, unbeknownst to the parties, there were two ships named "Peerless" sailing from Bombay on that day, which created a latent ambiguity with regard to the ship to which the contract referred. Nothing similar occurred in the instant case. In other words, nothing outside the four corners of the CBAs calls into question the meaning of the language used within the four corners of the CBAs. Indeed, that a Macomb County Executive once stated that defendant "provides retiree health benefits to eligible County retirees (and their eligible beneficiaries) for their lifetimes" is not even inconsistent with our conclusion that the CBAs do not require defendant to provide benefits to eligible retirees (and beneficiaries) for their lifetimes. Defendant, of course, remains free to provide greater benefits to retirees (and beneficiaries) than those required under the CBAs.
Other federal circuits have interpreted surviving-spouse provisions in a similar fashion. See, e.g., Barton v. Constellium Rolled Prod.-Ravenswood, LLC ,
Plaintiffs direct our attention to Bidlack v. Wheelabrator Corp. ,
While Serafino is unpublished, the Sixth Circuit later reaffirmed its analysis in Cooper ,
For this reason, Matthews v. Chicago Transit Auth. ,
The dissent relies on the same three provisions and concludes that these "imply that the County and the unions intended that healthcare benefits specific to retirees would last for those retirees' entire retirements. " For the reasons explained earlier in this opinion, we disagree. The dissent also contends that these provisions "differentiate these contracts from those at issue in Reese ." However, the dissent fails to recognize that these provisions are similar to provisions at issue in Tackett ; that Tackett rejected the Sixth Circuit's conclusion that these provisions "indicate[ ] an intent to vest retirees with lifetime benefits," Tackett , 574 U.S. at ----,
The dissent finds it "odd" that we "interpret[ ] the agreement as giving benefits for only a short time to any employee who retires near the end of a term, whereas an employee who retires near the beginning of the same CBA would be entitled to nearly three years of those very same benefits." However, that is simply how CBAs with a three-year duration operate. In other words, CBAs, by their nature, regularly expire and are replaced with new CBAs, meaning that both employees who retire and new employees who are hired near the end of the CBA will only be covered by the terms of that CBA until that CBA expires.
That the parties have modified the retiree-benefits provisions of the CBAs over time-see Defendant's Supplemental Brief, p. 16 ("[R]etiree healthcare benefits have been modified with nearly every CBA since 1987"); Exhibit 1 to Plaintiffs' Motion for Summary Disposition (tracking modifications to retiree-benefit provisions since 1989)-further evidences that the parties did not intend the benefits to be permanent or unalterable. See Cherry ,
This Court has already held that there is no constitutional right to retiree healthcare benefits, i.e., that such benefits are not " 'accrued financial benefits' " subject to protection from diminishment or impairment by Const 1963, art 9, § 24, and the parties here do not argue to the contrary. See Studier v. Mich. Pub. Sch. Employees' Retirement Bd. ,
We recognize that Arbuckle is somewhat distinguishable because in that case the agreements specifically provided that the prohibition against benefit coordination was to continue until the termination or amendment of the agreements, whereas in the instant case the specific provisions pertaining to retiree healthcare benefits are silent regarding their duration. However, as Gallo ,
Dissenting Opinion
The majority holds that the defendant, Macomb County (the County), is entitled to summary disposition because the County's contractual promise to provide retiree healthcare benefits does not extend beyond the duration of the County's collective-bargaining agreements (CBAs) with its employee unions. It reasons that the general durational clauses in the CBAs *621unambiguously govern that promise because the agreements neither include language exempting retiree healthcare benefits from that general period nor explicitly promise healthcare benefits for the retirees' lifetimes.
The plaintiffs, retired County employees, believe the specific promise of retirement healthcare extended beyond the general contract period. Their understanding has commonsense appeal: they thought retirement healthcare was a promise that they would have healthcare for the period of their retirement. They cite specific language in the agreements governing retiree healthcare to support their view.
I agree with the majority's understanding of the principles that guide our review of this dispute. But I disagree with its application of those principles to these agreements. Because the CBAs are ambiguous about whether the County promised retiree healthcare benefits for not more than three years, or instead for the full period of plaintiffs' retirements, I would send the question to the fact-finder, who may properly consider extrinsic evidence to resolve it. I respectfully dissent.
**328I. BACKGROUND
For nearly three decades, the County has provided healthcare benefits to its retired employees. Those benefits are described in the CBAs that the County entered into with the unions that represented various groups of County employees.
Each CBA also contained a general, three-year durational provision. The final article of the 2008-2010 CBAs, for example, provided, "This Agreement shall continue in full force and effect until December 31, 2010." The parties agree that earlier CBAs contained either this same durational clause (varying only in end date) or a substantially similar one. The historical practice was that at the end of every three-year period,
Beginning in 2009, in the middle of the 2008-2010 CBAs, the County unilaterally implemented changes in the retirees' healthcare benefits. According to the plaintiffs, these changes resulted in some retirees paying more for prescription copays, changed deductibles, and reduced plan options. The plaintiffs filed this class action on behalf of themselves and a class of about 1,600 retirees, all of whom retired under these **329CBAs and received retiree healthcare benefits from the County. The plaintiffs believe that the County violated the 2008-2010 CBAs by making the changes unilaterally, without the retirees' consent. The County responded that the benefit changes were consistent with and allowed by the CBAs.
But a more fundamental dispute arose. The plaintiffs sought a permanent injunction requiring the County to continue providing prechange healthcare benefits for the plaintiffs' lifetimes and to prevent the County from changing those benefits. According to the County, however, at no time did any of the CBAs (the 2008-2010 CBAs *622and their predecessors) provide a retiring employee with healthcare benefits for the retiree's lifetime. Instead, the County contends that the plaintiffs' right to receive healthcare benefits was subject to each CBA's three-year durational clause. Thus, the County argues, none of these plaintiffs had a right to continued healthcare benefits beyond any three-year term, absent a new contractual promise in a successive CBA. Or, put differently, each CBA only guaranteed retirement healthcare for the three-year period it governed. After that, the retirees had-and have-no right to future healthcare benefits, absent a new contractual promise from the County.
The plaintiffs, on the other hand, believe that the County promised to provide union members who retired during the term of a CBA with specified healthcare benefits for their retirements; that is, for the rest of their lives. They believe the CBAs, and three provisions in them in particular, support their view. Each provision specifically governs retiree healthcare.
One clause provided that coverage would end upon the death of the retiree or, if the retiree made a spousal **330election, continue for the retiree's spouse after the retiree's death (the survivor clause):
Coverage shall be limited to the current spouse of the retiree, at the time of retirement, provided such employee shall retire on or after January 1, 1974. Coverage for the eligible spouse will terminate upon the death of the retiree unless the retiree elects to exercise a retirement option whereby the eligible current spouse receives applicable retirement benefits following the death of the retiree.
Another clause required retirees to enroll in federally funded healthcare upon reaching age 65, after which the County's obligation was to provide only supplemental coverage (the supplemental-care clause):
Retired employees and/or their current spouse, upon reaching age 65, shall apply if eligible, and participate in the Medicare Program at their expense as required by the Federal Insurance Contribution Act, a part of the Social Security Program, at which time the Employer's obligation shall be only to provide "over 65 supplemental" hospital-medical benefit coverage. Failure to participate in the aforementioned Medicare Program, shall be cause for termination of Employer paid coverage of applicable hospital-medical benefits, as outlined herein for employees who retire and/or their current spouse.
Finally, the CBAs addressed temporarily suspending the coverage of any retiree who becomes gainfully employed (the subsequent-employment clause):
Employees who retire under the provisions of the Macomb County Employees' Retirement Ordinance, and/or their current spouse, who subsequently are gainfully employed, shall not be eligible for hospital medical benefits, during such period of gainful employment, as hereinafter defined: Gainful employment is defined as applying to retiree and/or spouse of retiree who are employed subsequent to the employee retirement. If such **331employment provides hospital-medical coverage for both retiree and spouse, the County is not obligated to provide said coverage unless and until the coverage of either person is terminated. If the coverage is not provided to retiree and spouse, the County will provide hospital-medical coverage for the person not covered. [Paragraph structure omitted.]
II. AMBIGUITY
The majority agrees with the County. The majority holds that because the CBAs *623do not expressly provide a separate end date for retiree healthcare benefits, the CBAs' general, three-year durational clauses unambiguously govern these benefits. The majority does not believe that the survivor clause, the supplemental-care clause, or the subsequent-employment clause create ambiguity because those events might occur during the three-year term of the agreement. And seeing no ambiguity, the majority (correctly) disregards the extrinsic evidence, such as the County's issuing of bonds to fund its retiree healthcare obligation and the many statements by County officials and representatives that support the plaintiffs' contention that the County's promise to provide retiree healthcare benefits extends far beyond 2010.
I agree with the majority's understanding of recent federal jurisprudence governing agreements between employers and their retired employees about healthcare benefits. See M&G Polymers USA, LLC v. Tackett ,
**332But I am not convinced that any of those principles compel the result reached by the majority. The question is whether these CBAs are ambiguous. The Tackett Court did not address whether there was ambiguity in the parties' CBA; instead, the Court rejected the Sixth Circuit's unique approach to this particular contractual question and remanded the case for the Court "to apply ordinary principles of contract law in the first instance." Tackett , 574 U.S. at ----,
CBAs must be interpreted "according to ordinary principles of contract law ...." Tackett , 574 U.S. at ----,
All of that is to say that a court should not engage in presumptions that favor either the plaintiffs or the County. But the implied terms make this a hard case.
**334Unlike in the CBA at issue in Reese , these CBAs did not tie retirement healthcare benefits to the general durational clause. And specific clauses in these CBAs governing eligibility for retirement healthcare imply that the County and the unions intended that healthcare benefits specific to retirees would last for those retirees' entire retirements.
General principles of contract law lead me to conclude that these contracts are ambiguous, because they are equally susceptible to more than one meaning. Barton-Spencer v. Farm Bureau Life Ins. Co. of Mich. ,
In my view, the general durational clause is doing more work for the majority than it should. These CBAs contain no provision that connects the promise of retiree healthcare benefits to the duration of any CBA. Cf. Reese , 583 U.S. at ----,
But the CBAs in this case contain provisions that imply the opposite conclusion. The CBAs' survivor clause, the supplemental-care clause, and the subsequent-employment clause each imply that retirement healthcare is a benefit that generally runs with retirement for life. In my view, these more specific provisions, the nature of the benefit, and the lack of a provision tying the benefits to the general durational clause (unlike in Reese ) creates ambiguity.
Yes, a retiree can die, become Medicare-eligible, or become re-employed within any given three-year term of a CBA. And, therefore, I agree with the majority that these provisions do not irreconcilably conflict with the three-year durational clause. But an irreconcilable conflict is not the only way a contract can be ambiguous. As this Court stated in Hall ,
Each of these provisions supports a reading that the CBAs promise retiree healthcare benefits for retirement (that is, for life) for those employees who become eligible for them during the term of the contract. For example, the survivor clause says that healthcare benefits for an eligible spouse "will terminate upon the death of the retiree unless the retiree elects to exercise a retirement option, whereby the eligible current spouse receives applicable retirement benefits following the death of the retiree." (Emphasis added.) This promise continues spousal coverage until the death of the retiree , and even beyond that for an indefinite period, if the retiree makes a spousal election. That is, even if the retiree-spouse dies before the CBA expires, the contractual language implies that the spousal benefits continue beyond any three-year term.
The supplemental-care clause and the subsequent-employment clause similarly support plaintiffs' reading of the CBAs. While it is possible for the triggering events to happen within the three-year term of a CBA, that durational limitation isn't the most commonsense reading of the language. The context is retirement , after all-that portion of life following work and extending to death. The parties to the CBAs might have intended the natural reading of the supplemental-care clause: that it offers supplemental coverage once a retiree becomes eligible for Medicare, which, for many employees who **337retire during a CBA, will be some time beyond that three-year period. See Consol. Rail Corp. v. R. Labor Executives' Ass'n ,
Understanding the retiree healthcare benefits to apply to retirement for those employees who enter that status during the term of the CBA is at least equally reasonable given the context. In my view, the majority's conclusion that the parties must have intended the opposite result-that the general durational clause limits retirement healthcare benefits to three years (or less, depending on when an employee retires)-doesn't account for the CBAs' implied terms, which differentiate these contracts from those at issue in Reese .
If these retiree healthcare benefits are guaranteed for no more than three years, then for any single retiring employee the length of the retirement benefit will depend solely on when that employee retires within the three-year period of the CBA. That is, the majority interprets the agreement as giving benefits **338for only a short time to any employee who retires near the end of a term, whereas an employee who retires near the beginning of the same CBA would be entitled to nearly three years of those very same benefits. It is an odd reading that results in the value of the retirement benefit varying with the arbitrary date of the employee's retirement, rather than years of service or any other factor.
Finally, I respectfully disagree with the majority that my approach to these CBAs is the same approach that the Supreme Court of the United States implicitly rejected in Tackett and Reese . Neither Tackett nor Reese -nor our own jurisprudence-compels the result the majority reaches.
**339under its framework, it is difficult to imagine under what circumstances a general durational clause will not control.
Given the patent ambiguity, I would reverse that part of the Court of Appeals' judgment remanding the case to the trial court for entry of summary disposition in favor of the plaintiffs, because the meaning of an ambiguous contract is a question that generally must be decided by the trier of fact.

III. RELIEF
The plaintiffs have identified extrinsic evidence that they believe suggests that the County promised retiree healthcare for retirement. The County's actuaries issued regular reports, beginning as early as 1993, describing the benefits as an "IOU" (I owe you)
**340to the County's future retirees. The County created a trust specifically for retiree healthcare, which it funded with tens of millions of dollars to satisfy its future obligations. The County issued bonds to fund that trust when it determined that current funding levels would not be enough to meet its future obligations "for the next 50 years." During labor negotiations, the County's representatives described the retiree healthcare as a "lifetime" benefit. Many retirees tell the same story: that representatives from the County assured them that their healthcare benefits would last their lifetimes. And the County's bargaining history might support the plaintiffs' view: while its position here is that retirement healthcare is only promised for the three years of each CBA, the County has continuously provided it to retirees in every CBA since 1986.
*628**341But the County has an explanation for all this evidence: it intends to continue providing such benefits to its retirees, even if it is not contractually obligated to do so. And the County's historical practice of renegotiating retiree healthcare and applying the new terms to past retirees might be evidence that supports its position.
The contracting parties' intent is a disputed question of fact; I believe the Court of Appeals and trial court both erred by determining that, on this record, summary disposition was appropriate. See Klapp ,
IV. CONCLUSION
I disagree with the majority's conclusion that these CBAs unambiguously limit retiree healthcare to the CBAs' general three-year durational clause. It is just as likely that the parties to these CBAs intended the promised retirement benefits to apply to an employees' entire retirement. I would conclude that there is ambiguity about the parties' intent, and I would let the fact-finder resolve it with the benefit of the extrinsic evidence from both sides.
I respectfully dissent.
Bernstein, J., concurred with McCormack, C.J.
**342Cavanagh, J., did not participate in the disposition of this case because the Court considered it before she assumed office.
The County entered into a different CBA with each bargaining unit, but the parties agree that the relevant language in each CBA is "materially similar."
The first round of CBAs expired on December 31, 1989.
I agree with the majority that the ambiguity identified by the Court of Appeals is a patent ambiguity, not a latent ambiguity. See Shay v. Aldrich ,
The majority concludes that an important difference between these CBAs and the agreement in Reese -the existence of language explicitly linking the providing of retiree healthcare benefits to the CBA's durational clause-was not "dispositive" to the Reese Court's analysis. Maybe not-the opinion doesn't say either way. But it was one of several provisions that the Court cited in concluding that the CBA was not ambiguous, none of which the Court proclaimed to be dispositive alone. See Reese , 583 U.S. at ----,
The majority acknowledges that ambiguity might be found (notwithstanding a general durational clause) if the CBA "tied benefits to an event that could only occur or would almost certainly not occur until after the expiration of the CBA[.]" Again, I acknowledge that there is no irreconcilable conflict here; events triggering the CBAs' survivor clause, supplemental-care clause, or subsequent-employment clause could occur before expiration of the CBA. But unlike the majority, I don't believe it is only "conceivabl [e ]" that these triggering events would occur beyond the expiration of the CBA. These CBAs permit an employee to retire at age 50 and receive both a pension and retiree healthcare benefits. For most employees who retire during a CBA's three-year-term, the triggering events (death or reaching age 65) are almost certain to occur beyond the expiration of that term.
The County says that every time it negotiated a CBA, both it and the union understood that the unions only represented the interests of active employees, not retirees. See Defendant's Supplemental Brief, p 16 (stating that "[t]he CBAs since 1986 have been negotiated with the County of Macomb by 23 Unions on behalf 'of regular employees,' generally effective every three years."). This approach is consistent with federal labor law, under which a union does not have to bargain on behalf of retired employees because they are no longer members of the bargaining unit. See Allied Chem. & Alkali Workers v. Pittsburgh Plate Glass Co. ,
This leads to an interesting question relating to the County's bargaining history with these unions. If the unions did not have to bargain on behalf of retired employees and the County did not have to continue providing healthcare to them, what are we to make of the fact that the parties continued to negotiate about the terms of retiree healthcare in successive CBAs and that those changes were applied to employees who retired under earlier agreements? On the one hand, the consistent practice of agreeing to new terms for retiree healthcare and applying those new terms to all retired employees (not just those who retired under the current agreement) might suggest that the parties did not believe the benefits lasted beyond the term of the contract. On the other hand, the continued coverage since 1989, even if the County did not have to provide healthcare for the already-retired employees, might be evidence that the County and the unions all believed that retiree healthcare was promised for retirement.
