PALMER, J.

In July, 2002, the plaintiff, Pack 2000, Inc., and the defendant, Eugene C. Cushman, entered into a series of agreements pursuant to which the defendant was to transfer the management and, ultimately, at the option of the plaintiff, the ownership of two Midas automobile repair shops to the plaintiff. The agreements also provided the plaintiff with options to purchase the realty on which the shops were located, on condition that the plaintiff, at the time it exercised the options, was and previously had been in compliance with the terms of the agreements. In August, 2003, the plaintiff sought to exercise the options, but the defendant refused to convey the properties, claiming that the plaintiff had not strictly complied with the terms of the agreements. The plaintiff thereafter brought the present actions, alleging entitlement to specific performance of the options to purchase the realty.1 Following a court trial, the court concluded that the plaintiff was entitled to specific performance of the options because it had substantially complied with the terms of the agreements. The defendant appealed to the Appellate Court, claiming that the trial court improperly had applied a standard of substantial compliance, rather than a standard of strict compliance, with the terms of the parties' agreements in determining whether the plaintiff had satisfied the conditions precedent for exercising the options. See Pack 2000, Inc. v. Cushman, 126 Conn.App. 339, 340-41, 345-46, 11 A.3d 181 (2011). The defendant also claimed that the evidence established that the plaintiff had not strictly complied with the agreements. Id., at 346, 11 A.3d 181. The Appellate Court agreed with both of the defendant's claims and, accordingly, reversed the judgments of the trial court and remanded the case to that court with direction to render judgments for the defendant. Id., at 341, 351, 11 A.3d 181. We granted the plaintiff's petition for certification to appeal, limited to the following issues: "Did the Appellate Court properly determine that lease/option agreements are subject to a strict compliance standard? If so, should the [judgment of the] Appellate Court be reversed under the applicable standard?" Pack 2000, Inc. v. Cushman, 301 Conn. 907, 19 A.3d 177 (2011). We agree with the plaintiff that, contrary to the conclusion of the Appellate Court, the trial court properly applied a standard of substantial rather than strict compliance in resolving the plaintiff's claim and, further, that the trial court properly determined that the plaintiff is entitled to specific performance of the options because it had substantially complied with the terms of the parties' agreements. We therefore reverse the judgment of the Appellate Court and remand the case to that court with direction to affirm the judgments of the trial court.

The opinion of the Appellate Court sets forth the following relevant facts and procedural history, as supplemented by the record. "In July, 2002, the plaintiff, the defendant and ARCO Corporation (ARCO),2 a corporation controlled by the defendant, entered into a business transaction in which two Midas [automobile repair] shops3 (shops) were to be transferred from ARCO to the plaintiff. As part of the transaction, the parties executed a number of agreements, including [1] two lease agreements, under which the defendant leased [to the plaintiff] the [real property on which] the shops are located... [2] a management agreement, under which the plaintiff assumed responsibility for the management and operation of the shops ... [3] a letter of intent ... and [4] two promissory notes. [The defendant, an experienced attorney, drafted all of the agreements between the parties.]

"Each lease agreement contains a clause... that provide[d] the plaintiff with an option to purchase the leased [property] subject to certain terms and conditions. The language of the two clauses is essentially identical. Each clause provides in relevant part: `So long as [the plaintiff] has been in compliance with the terms and conditions of this Lease, the Letter of Intent, and Management Agreement ... and is in compliance with such instruments when the option is exercised, [the plaintiff] shall have the option to purchase the real estate subject to this lease.... The option shall be exercised by [the plaintiff] giving [the defendant] three months advanced notice, in writing. The option may be exercised by giving the aforesaid notice between the date of this Lease [July 25, 2002] and the fifth anniversary of [the] same.'

"The management agreement also refers to the plaintiff's options to purchase the defendant's realty and contains the following language ... as it relates to the options: `The [plaintiff] shall be given an option to purchase the real estate upon which the shops are located. Said option shall be by separate agreement and signed by the titleholder and the party designated by [the plaintiff] to take title. Such option shall cite separate consideration and shall contain the terms as generally outlined herein. (a) Such option may be exercised between [the] date of commencement herein and the fifth anniversary of [the] same.... (f) [The plaintiff] must be in full compliance with this agreement and any lease agreement at the time of exercise.' [The management agreement also contains a provision granting the plaintiff an option to purchase the shops `[s]o long as [the plaintiff] is in compliance with all of the terms and conditions of [the management] agreement, the letter of intent and any option agreement....']

"In addition to the two lease agreements and the management agreement, the letter of intent also contains language that refers to the options [to purchase the realty]. It provides in relevant part: `[The plaintiff] has the option to purchase from [the defendant] the buildings and the land housing the [s]hops, if this agreement and the... Management Agreement are executed. The option is for five years from the date of the Management Agreement. The price will be as appraised.'

"Under the terms of the two lease agreements, the management agreement and the promissory notes, the plaintiff was required to make a number of periodic payments both to the defendant and to certain third parties in order to exercise the options. Specifically, the plaintiff was required to pay rent to the defendant by the first day of each month during the term of the lease[s], to make payments on both promissory notes by the eighth day of each month until the notes were fully paid and to pay all accounts, including, but not limited to, utilities, telephone service, real estate taxes, and hazard and liability insurance as well as an equipment lease. At trial, the defendant testified that timely payment of the aforementioned accounts was vital and that he informed the plaintiff that untimely payments would jeopardize his franchise agreements with Midas and his mortgages on the two shops.

"Nevertheless, the record reveals that the plaintiff was often late in making the aforementioned payments. Specifically, the record reveals that the following payments were late: the rent payment due on May 1, 2004; three payments on the promissory notes due on February 8, 2003, and May 8 and June 8, 2006; one payment to Groton Utilities, which resulted in a shutoff notice that the defendant forwarded to the plaintiff on January 23, 2003; several payments to a telephone company, which resulted in several collection letters and telephone calls that the defendant received in late 2002 and early 2003 as well as a threat to terminate telephone service to the defendant's unrelated business in March, 2003; two real estate tax installments on the New London shop due January 1, 2005, and January 1, 2007; one real estate tax installment on the Groton shop due July 1, 2007; twelve hazard and liability insurance installments between November, 2002, and January, 2004, that resulted in cancellation notices issued on July 30, 2003, and November 29, 2004; twenty health insurance installments between October, 2002, and September, 2005; and several installments under the terms of an equipment lease that resulted in several collection calls to the defendant in 2002 and 2003. [With respect to these late payments, however, the trial court found that all `were, on the whole, made within a commercially reasonable time' and, further, that the tardiness of the payments was attributable to `administrative inefficiency as opposed to financial insolvency.']

"On August 22, 2003, the plaintiff's vice president, M. Paulina Anderson, faxed a letter to the defendant in which she stated that she wanted `to finalize the purchase of the shops and exercise the option[s] to purchase the real estate by the end of 2003.' On August 29, 2003, Anderson sent a second letter to the defendant in which she sought information about ... possible appraisal[s] and indicated that Banterra Bank (bank) could not commit to financing the purchase until it had ascertained the value of the defendant's realty.

"On September 2, 2003, the defendant, on behalf of ARCO, sent a letter to Anderson in which he stated that the plaintiff was not in compliance with the terms and conditions of the management agreement. Specifically, the letter stated: `The installment payment regarding the ... Management Agreement which was due September 1, 2003 has not been received. Per the provisions of said agreement, the monthly installments are due on the first day of each month. Your monthly payments have been consistently late and have required telephone calls from [ARCO] nearly every month in order to prompt the payment. Timely payment of the note was and is a material condition of the agreement. As you have known from the inception, ARCO ... is dependent [on] timely payments from you in order to remain in compliance with its obligations concerning various mortgages. Your late payment for August put ARCO ... in default with one of its mortgagees. This is an intolerable circumstance. You are hereby put on notice that this late payment, and all of the prior late payments, and any future late payments [put] you out of compliance with the terms and conditions of the Management Agreement. Subsequent acceptance of the September, 2003 payment (or any future payment tendered after the date due) will not cure the non-compliance, nor does ARCO ... waive any rights or consequences which flow from your non-compliance.' There is no record of the plaintiff having specifically responded to this letter. [It is apparent, however, that the parties treated this letter as the defendant's repudiation of the plaintiff's right to exercise the purchase options due to its late payments.]

"On May 16 and 19, 2006, the plaintiff again sought to exercise the options to purchase the defendant's realty. At that time, however, the payment on one of the promissory notes that was due on May 8, 2006, had not been paid.

"On July 17, 2006, the plaintiff commenced these actions against the defendant claiming that it was entitled to specific performance of the options to purchase the defendant's realty. In its disclosure of defense, filed on August 4, 2006, the defendant argued that the plaintiff's claim was without merit because, among other things, the plaintiff had not complied with the terms of one of the promissory notes and the conditions of the lease at the time of its attempt to exercise the options, and, therefore, the options had been forfeited or terminated by the plaintiff's fault or noncompliance. As of the date of trial, the plaintiff had paid the defendant in excess of $600,000 in rent under the terms of the lease agreements, $700,000 under the terms of the promissory notes and was not in arrears on its financial obligations under the terms of any of the aforementioned agreements." (Footnotes altered.) Pack 2000, Inc. v. Cushman, supra, 126 Conn. App. at 341-45, 11 A.3d 181.

At trial, the defendant testified that, although he believed that many of the late payments "technically were [in] noncompliance" with the parties' agreements, he did not take any action against the plaintiff with respect to those payments until after the plaintiff sought to exercise the options because it was not until then that the defendant decided he had "had enough." As the defendant stated, he did not "at any time" prior to August 22, 2003, "press" any of these late payments as grounds for terminating the options, apparently because he did not believe that there was sufficient need or reason to do so. The defendant further testified that, in view of the nature of the parties' transaction, in particular, the fact that all of the accounts remained in his name, so that he, rather than the plaintiff, received all of the monthly billing statements, the defendant "understood that [initially, there] were going to [be] some bumps...." "There were all kinds of [tele]phone calls back and forth between [the defendant's] organization and [the plaintiff's] organization, [as the parties were] trying to figure out [who was] paying which bill, which responsibility, what adjustments." Furthermore, each of the agreements contains a default provision pursuant to which the defendant was required to give written notice of a default, after which the plaintiff has either twenty days (lease agreements) or thirty days (management agreement) to cure the default. "Default" is defined in the management agreement to include, "but not be limited to, nonpayment of any obligation...." The defendant, however, never gave notice of a default prior to the plaintiff's request to exercise the options.

The defendant also testified that, although he was aware that compliance with the lease and management agreements was a condition precedent to the plaintiff's right to exercise both the options to purchase the shops and the options to purchase the real property, he had "no problem" with the plaintiff exercising the shop options. Specifically, the defendant testified, with respect to the shop options, that the plaintiff "[has not] been defaulted. [The plaintiff has] not always been in compliance; but [it has] made payments. I'm not concerned with that." The defendant also testified that, "[i]f [the plaintiff] wanted to pay cash for ... the Groton or New London shops and pay down [the promissory] note, I would not consider [the plaintiff] in noncompliance. I would agree to that. I would let [the plaintiff] do that."

"On August 11, 2008, the trial court rendered judgments in favor of the plaintiff. The court determined that the plaintiff had retained the right to exercise the options because it had substantially complied with the terms and conditions of the [parties' agreements]. [In support of this conclusion, the court found that the late payments generally had been made within a commercially reasonable time.] The court also determined that the plaintiff had effectively exercised the options on August 22, 2003, and was entitled to specific performance.4 The court, therefore, ordered the defendant to sell the realty at issue to the plaintiff under the terms of their agreements."5 (Footnote added.) Pack 2000, Inc. v. Cushman, supra, 126 Conn.App. at 345-46, 11 A.3d 181. In reaching its conclusion, the trial court observed that, although a strict compliance standard applies to the "actual exercise of an option"; (emphasis omitted); when an option is conditioned on a lessee's compliance with a lease, a substantial rather than strict compliance standard applies to "the issue of whether a lessee possesse[s] the right to exercise an option," that is, to the issue of the sufficiency of the lessee's performance under the lease. With respect to the issue of specific performance, the trial court found that the defendant had "enjoyed, and continues to enjoy, the benefits of the agreements with the plaintiff, including the receipt of [more than] $1.3 million since 2002." The trial court concluded that "[t]o allow [the defendant] to enjoy [all of] the benefits of his bargain with [the] plaintiff while avoiding the less financially attractive elements of the transaction," namely, conveyance of the real property on which the shops are located, "would be inequitable." In a subsequent articulation, the trial court stated that the plaintiff had established by a preponderance of the evidence that it was "ready, willing and able to exercise the options" at the time that it sought to do so.

The defendant appealed to the Appellate Court from the judgments of the trial court, claiming, inter alia, that the trial court was required to apply a strict rather than a substantial compliance standard in determining whether the plaintiff had satisfied the terms of the lease and management agreements and, in addition, that the trial court incorrectly concluded that the plaintiff had retained the right to exercise the options notwithstanding its late payments to the defendant. See Pack 2000, Inc. v. Cushman, supra, 126 Conn.App. at 340-41, 11 A.3d 181. The Appellate Court agreed with the defendant. Id., at 341, 11 A.3d 181. Relying primarily on Brauer v. Freccia, 159 Conn. 289, 268 A.2d 645 (1970), the Appellate Court explained that this court "has determined, albeit implicitly, that when a lease provides the lessee with the option to purchase realty subject to certain terms and conditions, the right of the lessee to exercise the option is contingent on the lessee's strict compliance with those terms and conditions." Pack 2000, Inc. v. Cushman, supra, at 347, 11 A.3d 181. The Appellate Court further determined that, because the plaintiff was obligated under the lease "to make periodic payments to the defendant and to certain third parties by specified deadlines"; id., at 350, 11 A.3d 181; but was "often late in making [those] required payments"; id., at 351, 11 A.3d 181; the plaintiff's right to enforce the options had expired prior to August 22, 2003, the date on which, according to the trial court, the plaintiff had effectively exercised the options. See id., at 346, 350-51, 11 A.3d 181. In accordance with these conclusions, the Appellate Court reversed the judgments of the trial court and remanded the case to that court with direction to render judgments for the defendant.6 Id., at 351, 11 A.3d 181.

On appeal to this court, the plaintiff challenges the Appellate Court's determination that the trial court improperly applied a substantial compliance standard in concluding that the plaintiff was entitled to specific performance of the options. For the reasons set forth hereinafter, we agree with the plaintiff that, when a purchase option is conditioned on a lessee's compliance with the terms of a lease, in the absence of express contractual language to the contrary, the option is enforceable against the lessor if the lessee has substantially complied with the lease terms and the lessee is not in default at the time it seeks to exercise the option. We also agree with the plaintiff that the trial court reasonably found that the plaintiff had substantially complied with the lease and management agreements. Finally, we reject the defendant's claim that the judgment of the Appellate Court may be affirmed on the alternative ground that the evidence does not support the trial court's finding that the plaintiff was ready, willing and able to purchase the properties at the time it sought to do so.

I

We first address the plaintiff's claim that the Appellate Court incorrectly concluded that the plaintiff forfeited the right to exercise the options because it failed to make certain periodic payments to the defendant and other third parties by deadlines specified in the parties' agreements.7 In support of its claim, the plaintiff maintains that the Appellate Court misinterpreted and, as a result, misapplied our decision in Brauer, which, according to the plaintiff, is entirely consistent with the general rule that a lessee is entitled to enforcement of the lease provisions if it has complied substantially with its obligations under the lease. The plaintiff further contends that this general rule requiring substantial rather than strict compliance with the lease terms applies to its performance under the lease and management agreements.

Several well established principles guide our analysis of the plaintiff's claim. As the Appellate Court correctly acknowledged, "[t]he general rule with respect to compliance with contract terms... is not one of strict compliance, but substantial compliance." (Internal quotation marks omitted.) Pack 2000, Inc. v. Cushman, supra, 126 Conn.App. at 348-49, 11 A.3d 181; accord ED Construction, Inc. v. CNA Ins. Co., 130 Conn.App. at 391, 410, 24 A.3d 1 (2011); 15 R. Lord, Williston on Contracts (4th Ed. 2000) § 44:52, p. 217. "The doctrine of substantial compliance is closely intertwined with the doctrine of substantial performance." Pack 2000, Inc. v. Cushman, supra, at 349, 11 A.3d 181. "The doctrine of substantial performance shields contracting parties from the harsh effects of being held to the letter of their agreements. Pursuant to the doctrine of substantial performance, a technical breach of the terms of a contract is excused, not because compliance with the terms is objectively impossible, but because actual performance is so similar to the required performance that any breach that may have been committed is immaterial." (Internal quotation marks omitted.) Id.; accord Clem Martone Construction, LLC v. DePino, 145 Conn.App. 316, 336, 77 A.3d 760, cert. denied, 310 Conn. 947, 80 A.3d 906 (2013); 15 R. Lord, supra, § 44:52, at pp. 221-22.

As this court recently has observed, an option to purchase, like the one at issue in the present case, operates as "a continuing offer to sell, irrevocable until the expiration of the time period fixed by agreement of the parties, which creates in the option holder the power to form a binding contract by accepting the offer." (Internal quotation marks omitted.) Bayer v. Showmotion, Inc., 292 Conn. 381, 409, 973 A.2d 1229 (2009); see also Parkway Trailer Sales, Inc. v. Wooldridge Bros., Inc., 148 Conn. 21, 25, 166 A.2d 710 (1960) (tenant's exercise of purchase option in lease resulted in "a binding bilateral contract ... obligat[ing] [the landlord] to convey title by good and sufficient deed and obligat[ing] [the tenant] to accept the deed and pay the purchase price"). "It is widely accepted that, upon exercise of the option, the lease is extinguished, and the relationship of landlord and tenant becomes that of vendor and vendee." Bayer v. Showmotion, Inc., supra, at 414, 973 A.2d 1229. Furthermore, in light of this change in the parties' relationship following the lessee's timely exercise of the option, "[the lessors cannot] rely on alleged breaches occurring after [the lessee's] exercise as grounds for forfeiture." Summa Corp. v. Richardson, 93 Nev. 228, 235, 564 P.2d 181 (1977).

With respect to the actual exercise of the option, "[t]o be effective, an acceptance of an offer under an option contract must be unequivocal, unconditional, and in exact accord with the terms of the option.... If an option contract provides for payment of all or a portion of the purchase price in order to exercise the option, the optionee ... must not only accept the offer but pay or tender the agreed amount within the prescribed time." (Internal quotation marks omitted.) Bayer v. Showmotion, Inc., supra, 292 Conn. at 409, 973 A.2d 1229. "[I]n order to determine whether the [plaintiff] formed a binding contract with [the defendant] by exercising its option to purchase the property, we ... review the terms of the [applicable agreements] to determine whether the [plaintiff's exercise] was unequivocal, unconditional, and in exact accord with the terms of the [applicable agreements]." (Internal quotation marks omitted.) Id. "Whether the performance of a certain act by a party to a contract is a condition precedent to the duty of the other party to act depends on the intent of the parties as expressed in the contract and read in the light of the circumstances surrounding the execution of the instrument."8 Brauer v. Freccia, supra, 159 Conn. at 293, 268 A.2d 645.

With these principles in mind, we now address the plaintiff's claim that the Appellate Court, in reversing the judgments of the trial court, improperly concluded that the plaintiff had forfeited its right to exercise the options because it did not comply strictly with the lease provisions, a conclusion that, in the Appellate Court's view, was "implicitly" mandated by our decision in Brauer. Pack 2000, Inc. v. Cushman, supra, 126 Conn.App. at 347, 11 A.3d 181. Because the Appellate Court's reliance on Brauer is misplaced, we turn first to an examination of that case.

In Brauer, the trial court denied the lessees' request for specific performance of an option predicated on its finding that the lessees were seven months in arrears on their rental payments when they sought to exercise the option; see Brauer v. Freccia, supra, 159 Conn. at 292-93, 268 A.2d 645; and because the option was expressly conditioned on the lessees having "duly and punctually fulfilled all the provisions, agreements, covenants and conditions of [the] lease." (Internal quotation marks omitted.) Id., at 293, 268 A.2d 645. Although the lessees subsequently attempted to tender payment in full after seeking to invoke the option provision of the lease; see id., at 292, 268 A.2d 645; the trial court concluded "that the payment of all rent due under the lease was a condition precedent to the [lessees'] right to exercise the option to purchase; that the conduct of the [lessor in failing to terminate the lease for nonpayment of rent] did not constitute a waiver of [his] rights and did not estop [him] from relying on the provision of the option [that] required prompt payment of the rent; that the failure to pay the rent for [seven] months ... was due to gross negligence; that the failure to pay rent when due was not the result of accident, mistake or illness; and that the [lessees] were not entitled to equitable relief." Id., at 292-93, 268 A.2d 645.

In affirming the judgment of the trial court, this court stated that the option "clearly indicate[d] that the [lessor's] duty to comply with the terms of the option was conditioned [on] the [lessees'] punctual performance of their obligations under the lease. A tenant who fails to meet the named conditions of [a] lease defeats his right to rely on it when he makes an effort to purchase the property pursuant to the option in the lease." Id., at 293-94, 268 A.2d 645. This court specifically characterized the language imposing the punctuality requirement as "lucid and unambiguous...." Id., at 293, 268 A.2d 645. This court therefore concluded that the trial court correctly had determined that, "since the [lessees] had failed to perform their obligations under the lease, the right to enforce the option to purchase was not in existence and the [lessor was] under no obligation to convey the property." Id., at 294, 268 A.2d 645.

In Brauer, it is apparent that the lessees' breaches were material: they were seven months in arrears on rent at the time they sought to exercise the option, which, under the terms of the lease, was expressly conditioned on the prompt payment of rent. Contrary to the determination of the Appellate Court in the present case, however, there is nothing in Brauer to suggest that a nonmaterial breach of the lease also would have defeated the option rights of the lessees in that case.9 Although we had no occasion to address that issue in Brauer because the lessees' breach in Brauer was material by any objectively reasonable standard, courts that have addressed the issue uniformly have concluded that a nonmaterial breach of a lease does not extinguish a lessee's rights under a purchase option provision. See, e.g., Bachorz v. Miller-Forslund, 703 F.3d 27, 35 (1st Cir. 2012) ("minor, immaterial or inconsequential breaches, which do not prejudice the lessor, will not prevent a lessee from exercising an option" [internal quotation marks omitted]); Trinity Realty I, LLC v. Chazumba, LLC, 77 Mass.App. 911, 912, 931 N.E.2d 510 (2010) (lessee's substantial compliance with lease terms rendered lessee's performance under lease adequate to maintain its right to exercise option); Panhandle Rehabilitation Center, Inc. v. Larson, 205 Neb. 605, 610-11, 288 N.W.2d 743 (1980) (lessee was entitled to specific performance of option when lessee substantially performed all obligations under lease); Cimina v. Bronich, 517 Pa. 378, 386-87, 537 A.2d 1355 (1988) (lessee's failure to pay real estate taxes, although technical breach of lease agreement, was immaterial and did not bar lessee from exercising purchase option); Rowe v. Dorman, Texas Court of Appeals, Docket No. 06-12-00024-CV, 2012 WL 5266317 (Tex.App. October 18, 2012) (lessee's overall performance of its obligations under lease was sufficient to defeat lessor's claim that lessee's failure to make, inter alia, certain rental and tax payments in timely manner foreclosed lessee from exercising purchase option under lease). In fact, the defendant has not identified a single case, and our research has not revealed one, in which a court has applied a more stringent standard of compliance for the purpose of determining whether a lessee had forfeited his right to exercise a lease purchase option. We conclude, therefore, that, when an option is conditioned on a lessee's compliance with a lease, in the absence of explicit contractual language to the contrary, a substantial rather than strict compliance standard applies so that, if the lessee is not in material breach of the lease when he seeks to exercise the option and has not previously been defaulted under the terms of the lease, the option is enforceable against the lessor.10

In reaching its determination to the contrary, the Appellate Court mistakenly relied on the general principle that an option must be exercised in strict accordance with its terms. See Pack 2000, Inc. v. Cushman, supra, 126 Conn.App. at 349, 11 A.3d 181 ("strict compliance is now the rule in many American jurisdictions"). This principle, however, applies solely to the lessee's acceptance or "exercise" of an option. "The `exercise' of an option is merely the election of the optionee to purchase the property. By the use of the word `accept' in a particular option contract, the parties mean the same as `exercising' the option." (Footnote omitted.) 92 C.J.S. 143, Vendor and Purchaser § 171 (2010). "An option does not constitute a sale or a contract to sell, and it cannot be enforced as a contract by either party thereto until it is exercised by acceptance of the offer." (Footnote omitted.) Id., at pp. 143-44. "The election to exercise an option must be made in the way and manner prescribed by law or specified in the option contract or in the form provided by its terms." (Footnotes omitted.) Id., at p. 144. Thus, the cases on which the Appellate Court relied to support its conclusion that the trial court improperly had applied a standard of substantial rather than strict compliance are inapposite because they all involved the application of the rule of strict compliance when the lessee failed to exercise the purchase option in the manner prescribed by the option.11 See, e.g., LeBaron Homes, Inc. v. Pontiac Housing Fund, Inc., 319 Mich. 310, 314-15, 29 N.W.2d 704 (1947) (no evidence that lessee tendered payment as required by option); Raanan v. Tom's Triangle, Inc., 303 App. Div.2d 668, 669, 758 N.Y.S.2d 343 (2003) ("the [lessees] did not comply with the option agreement, as extended, having neither executed the agreed-upon contract of sale, nor tendered the down payment specified therein"); Zeidman v. Davis, 161 Tex. 496, 499, 342 S.W.2d 555 (1961) (lessee failed to exercise option within time prescribed in agreement). As another court has explained, and as our own case law makes clear, "cases and authorities [that] suggest vigorous compliance with the requirements of option conditions . . . tend to deal with flaws in the exercise of an option, e.g., failure to give notice of the exercise of an option on time, Donovan Motor Car Co. v. Niles, 246 Mass. 106, 107 [140 N.E. 304] (1923); failure to offer the purchase price on exercise of an option, Hunt v. Bassett, 269 Mass. 298, 302-303 [168 N.E. 783] (1929); [or] failure to give written notice and furnish [a] cashier's check, Epton v. CBC Corp., 48 Ill.App.2d 274, [280-87, 197 N.E.2d 727] (1964)." Westinghouse Broadcasting Co. v. New England Patriots Football Club, Inc., 10 Mass.App. 70, 73-74, 406 N.E.2d 399 (1980); see also Smith v. Hevro Realty Corp., 199 Conn. 330, 338-40, 507 A.2d 980 (1986) (exercise of option was ineffective when lessee failed to tender payment at time of exercise as required by option); Howard-Arnold, Inc. v. T.N.T. Realty, Inc., 145 Conn.App. 696, 704-705, 77 A.3d 165 (lessee was not entitled to specific performance of option to purchase when it had not tendered payment in accordance with terms of lease agreement), cert. granted, 310 Conn. 940, 79 A.3d 892 (2013). Because, in the present case, the defendant does not claim that the plaintiff failed to exercise the purchase options in accordance with the terms of the parties' agreements, the Appellate Court's reliance on case law addressing that situation was misplaced.12

The defendant finally contends that, even if a substantial compliance standard applied to the plaintiff's performance under the parties' agreements, the trial court incorrectly concluded that the plaintiff had substantially complied with those agreements. Whether a party to a contract substantially performs its obligations thereunder is ordinarily a question of fact to be determined by the fact finder. See, e.g., Nor'easter Group, Inc. v. Colossale Concrete, Inc., 207 Conn. 468, 472, 542 A.2d 692 (1988). Of course, it is not the function of this court to second-guess the reasonable factual findings of the trial court; rather, we must accept those findings unless they are clearly erroneous. "A finding of fact is clearly erroneous when there is no evidence in the record to support it ... or when although there is evidence to support it, the reviewing court on the entire evidence is left with the definite and firm conviction that a mistake has been committed." (Internal quotation marks omitted.) 418 Meadow Street Associates, LLC v. Clean Air Partners, LLC, 304 Conn. 820, 829, 43 A.3d 607 (2012). "[W]hat constitutes full performance generally depends [on] the construction of the contract in light of surrounding circumstances." 17A Am.Jur.2d 569, Contracts § 611 (2004). "An important factor [is] whether the deviation ... defeated the contract's purpose...." Id., § 619, at p. 577. "Substantial performance occurs when, although the conditions of the contract have been deviated from in trifling particulars not materially detracting from the benefit the other party would derive from a literal performance, [the defendant] has received substantially the benefit he expected, and is, therefore, bound to [perform]." (Internal quotation marks omitted.) Western Distributing Co. v. Diodosio, 841 P.2d 1053, 1058 (Colo.1992).

Applying these principles to the present case, we conclude that the trial court's finding that the plaintiff substantially complied with the parties' agreements is supported by the record. As the trial court found, and the defendant does not dispute, the defendant has received and continues to receive the full economic benefit of his bargain with the plaintiff. Furthermore, the defendant did not inform the plaintiff that its late payments constituted a default under the lease agreements until after the plaintiff sought to exercise its options. It bears emphasis, moreover, that none of the parties' agreements specifies a payment date for any of the plaintiff's financial obligations except for the payment of rent, which is due on the first of the month, and payment on the promissory notes, which is due on the eighth of the month. With respect to all other obligations, however, the management agreement simply provides that "[the plaintiff] agrees to ... [pay] all accounts including, but not limited to ... utilities, payroll, insurance, franchise fees and royalties, trade accounts, real estate and personal property taxes, and maintenance of all equipment, facilities, furniture, fixtures and improvements." There is no evidence that the plaintiff was not in full compliance with all of its financial obligations to the defendant as of August 22, 2003, the date on which the plaintiff effectively exercised the options to purchase the properties. Indeed, with respect to the litany of late payments identified in some detail by the Appellate Court, most are payments that occurred after August 22, 2003. See Pack 2000, Inc. v. Cushman, supra, 126 Conn. App. at 343-44, 11 A.3d 181. Although two categories of late payments, namely, health insurance and equipment leases, occurred during periods that include August, 2003, there is no finding by the trial court that any such payment was outstanding on August 22, 2003, and the defendant makes no such claim.

In an attempt to demonstrate that the trial court reasonably could not have concluded that the plaintiff was in substantial compliance with the terms of the parties' agreements, the defendant refers to a number of tardy utility, insurance and equipment lease payments that the plaintiff tendered prior to its request to exercise the options. The defendant's contention appears to be that, cumulatively, these payments constituted a material breach of the parties' agreements, and that such a breach is inconsistent with a finding of substantial compliance. As we previously indicated, however, the trial court found that the late payments "were, on the whole, made within in a commercially reasonable time." Moreover, although the defendant undoubtedly found some of those late payments to be frustrating and annoying, there is no evidence that they resulted in any financial loss to the defendant. As the plaintiff notes, most of the payments were for very modest amounts in relation to the significant payments that the defendant received under the agreements.13

The defendant's contention that the trial court was required to find that these late payments constituted a substantial and material breach of the parties' agreements, sufficient to justify terminating the plaintiff's purchase options under those agreements, is also difficult to square with the defendant's testimony that he understood and expected that there would be problems of this nature because all of the billing statements for the plaintiff's business were sent to the defendant's office, even though those statements pertained both to the plaintiff's and the defendant's businesses. According to the defendant, after he received a bill, he would determine the plaintiff's proportionate share and then forward a copy of the bill to the plaintiff for payment. It therefore is hardly surprising, as the defendant testified, that this arrangement resulted in "all kinds of [tele]phone calls back and forth between [the defendant's] organization and [the plaintiff's] organization, [as the parties were] trying to figure out [who was] paying which bill, which responsibility, what adjustments."

It also bears emphasis that the defendant, an experienced attorney, drafted the parties' agreements. It stands to reason that if the defendant had wanted to condition the plaintiff's option rights on the plaintiff's punctual fulfillment of some or all of the terms of the agreements, he readily could have incorporated such a provision into the agreements. See Brauer v. Freccia, supra, 159 Conn. at 293-94, 268 A.2d 645 (lessor was bound under lease option clause only "if the [l]essees shall have duly and punctually fulfilled all the provisions, agreements, covenants and conditions of [the] lease" [internal quotation marks omitted]). As it stands, however, the agreements do not even specify a payment date for the plaintiff's secondary obligations, which constitute the bulk of the payments at issue. The agreements also do not contain a provision stating that time is of the essence with respect to any payment. It is well settled that, "[when] a time for performance is stated in an agreement, a party's tender of performance within a reasonable time thereafter will be considered substantial performance unless the parties intended that time for performance be of the essence. See J. Calamari & J. Perillo, [The Law of] Contracts (2d Ed. [1977]) § 11-22, pp. 409-10. [When] the agreement does not specifically state that time is of the essence, it is presumed not to be unless the parties have expressed a contrary intent." Mihalyak v. Mihalyak, 11 Conn.App. 610, 616, 529 A.2d 213 (1987). Courts have applied this rule to a lessee's performance under a lease when a lessor claimed that untimely payments terminated the lessee's right to exercise an option. See, e.g., Robinson v. Cline, 255 Ark. 571, 574, 501 S.W.2d 244 (1973) (lessee did not lose right to enforce option to purchase on basis of failure to tender timely rental payments when there was no provision in lease for forfeiture based on untimely payments and no "time is of the essence" clause in lease [internal quotation marks omitted]); Continental Oil Co. v. McNair Realty Co., 137 Mont. 410, 427, 353 P.2d 100 (1960) ("[when] a lease with [an] option to purchase [did] not state that time [was] of the essence, [the] failure of the optionee to perform the covenants strictly at the time they may or should be performed [did] not cause him to lose his right to specific performance of the option"). The fact that the parties' agreements in the present case do not specify that time is of the essence, or provide a payment date for the plaintiff's myriad secondary financial obligations, reinforces the trial court's finding that the late payments at issue did not materially impair the rights that the defendant bargained for when he and the plaintiff entered into the agreements.

II

We next address the defendant's claim that the Appellate Court's judgment should be affirmed on the alternative ground that the plaintiff failed to establish that it was financially able to purchase the realty when it sought to exercise the options, and, as a result, the plaintiff failed to establish entitlement to specific performance of the options. In support of this claim, the defendant relies on the principle that a buyer seeking specific performance of a contract for the sale of real property must demonstrate his or her financial ability to purchase the property, even if the seller has repudiated the contract without justification. See, e.g., Steiner v. Bran Park Associates, 216 Conn. 419, 423, 582 A.2d 173 (1990) ("A buyer seeking specific performance must prove that he was ready, willing and able to purchase the property.... A buyer must prove his financial ability to go forward even when a seller entirely refuses to participate in a closing." [Citations omitted; internal quotation marks omitted.]). The defendant further contends that the trial court's finding that the plaintiff was ready, willing and able to make those purchases on August 22, 2003, was clearly erroneous, first, because there is no evidence of the plaintiff's financial condition at the time it sought to exercise the options and no evidence demonstrating that the plaintiff had obtained the necessary financing, and, second, because there is nothing in the record to indicate how much the plaintiff would have had available to pay for the realty. We disagree with the defendant.

The following facts and procedural history are relevant to our analysis of this issue. On April 2, 2009, the Appellate Court directed the trial court to articulate, inter alia, whether the court found that the plaintiff had established that it was ready, willing and able to purchase the properties when it sought to do so in August, 2003.14 In its articulation, the trial court first noted that the defendant claimed that the plaintiff was required to present evidence of a mortgage commitment in order to demonstrate that it was financially able to complete the purchases. Relying on Romaniello v. Pensiero, 21 Conn.App. 57, 61, 571 A.2d 145 (1990), the trial court concluded that, although proof of a mortgage commitment may be necessary in some cases, it is unnecessary when, as in the present case, the lessor has refused to convey the property after a lessee's valid exercise of an option to purchase. In such circumstances, the court concluded, the lessee need only prove by a preponderance of the evidence that it "could have obtained a mortgage commitment" when it sought to exercise the option. (Internal quotation marks omitted.) The trial court further concluded that, although "[the] plaintiff did not present specific evidence at trial regarding its financial situation at the time it sought to exercise the options, the surrounding circumstances fully support[ed] the conclusion that [the] plaintiff could have procured a mortgage commitment at that time."

In support of this conclusion, that trial court noted that, at the time of trial, the properties at issue had produced income sufficient to enable the plaintiff to pay the defendant in excess of $1.3 million under the lease and promissory notes. The trial court also credited the testimony of the plaintiff's vice president, Anderson, that the plaintiff "always was ready" to close, that a loan was "all set up" when the plaintiff sought to exercise the options, and that the only thing the plaintiff needed to finalize the loan was the defendant's cooperation in procuring the appraisals. As further evidence of the plaintiff's sound financial condition during the relevant time frame, the trial court also relied on the fact that the plaintiff had successfully purchased a similar property from the defendant in March, 2005. Finally, the trial court observed that the defendant had presented "[no] evidence that [the] plaintiff was in a compromised financial position at the time it sought to exercise the options.... [The] defendant's evidence of [the] plaintiff's purported inability to procure credit was limited to evidence of [the] plaintiff's late payments to [the] defendant, which appear to the court to have been caused by administrative inefficiency as opposed to financial insolvency." In addition to the foregoing findings, there was uncontroverted testimony that, at the time of trial, the plaintiff was operating twenty-two Midas shops in seven different states and had successfully purchased thirty-two Midas shops since 1991. Because this evidence was sufficient to support the trial court's finding that the plaintiff was ready, willing and able to purchase the properties, we will not disturb that finding. See Steiner v. Bran Park Associates, supra, 216 Conn. at 423-24, 582 A.2d 173 ("Whether a buyer [seeking specific performance of a contract to purchase real estate] has the requisite financial ability [to go forward with the purchase of the property] is a question of fact.... A trial court's finding of [financial] inability, which involves a factual issue, will not be reversed unless it is clearly erroneous." [Citations omitted; internal quotation marks omitted.]).

In support of his claim that the trial court's finding with respect to the plaintiff's financial ability was clearly erroneous, the plaintiff relies on this court's statement in Frumento v. Mezzanotte, 192 Conn. 606, 473 A.2d 1193 (1984), that, "when a purchaser of land is left to depend [on] a purchase price loan from a third party who is in no way bound to furnish such funds, the purchaser cannot be considered to be able to perform so as to be entitled to specific performance." Id., at 617, 473 A.2d 1193. In a later case, however, we clarified that Frumento "did not hold that in every case a buyer must have a written commitment from a financial backer"; (emphasis omitted) Steiner v. Bran Park Associates, supra, 216 Conn. at 425, 582 A.2d 173; rather, "what constitutes [financial] ability is a question of fact to be determined in light of the circumstances of the particular case." (Emphasis added; internal quotation marks omitted.) Id., at 424, 582 A.2d 173.

The facts of Frumento are readily distinguishable from the present case. In Frumento, a prospective buyer brought an action for specific performance of a contract to purchase real property after the prospective seller refused to sell. Frumento v. Mezzanotte, supra, 192 Conn. at 610, 473 A.2d 1193. The trial court concluded that the buyer was not entitled to specific performance because he failed to establish that he was financially able to tender the purchase price of $35,000. See id., at 610-11, 473 A.2d 1193. In affirming the trial court's judgment, this court noted that the only evidence that the buyer presented to establish his financial wherewithal to complete the purchase were two bank statements indicating balances that were nowhere near sufficient to cover the purchase price, and "his own testimony regarding his ability to secure a loan from his parents. [The buyer] offered no evidence of any promise or commitment by his parents to make any loan." Id., at 616, 473 A.2d 1193. "He further testified that he had no commitment from a bank to lend him money, and that he was to tender cash at the closing." Id., at 615, 473 A.2d 1193. In light of these facts, this court concluded that the trial court's finding that the buyer had not sustained his burden of proving that he was ready, willing and able to purchase the subject property was not clearly erroneous. Id., at 618, 473 A.2d 1193.

In contrast to Frumento, there was ample evidence in the present case from which the trial court reasonably could find that the plaintiff was financially able to complete the purchase. That evidence included that the plaintiff already had paid the defendant in excess of $1.3 million, the plaintiff was financially able to purchase a similar property from the defendant in 2005, and the plaintiff already owned twenty-two other Midas shops. In light of this evidence and Anderson's testimony that the only impediment to finalizing a loan in August, 2003, was the defendant's refusal to cooperate in the procurement of the appraisals, it was reasonable for the trial court to find that the plaintiff would have been able to obtain whatever financing it may have needed to complete the purchase if the defendant had not repudiated the plaintiff's right to purchase the properties in the first place. Cf. Romaniello v. Pensiero, supra, 21 Conn.App. at 61, 571 A.2d 145 ("Although a plaintiff seeking specific performance of a sales contract must prove that he was ready, willing and able to effectuate the sale, he need not make a formal tender of the purchase price in the event that the [seller] breaches the contract.... The law does not require a party to proceed with preparations for performance if such preparations would be futile.... Here, the [buyer] was not required to ... seek a mortgage commitment before a sales contract had been prepared. Such acts, in light of the [sellers'] refusal to perform, would indeed have been futile, since mortgage commitments are based on particular values at particular points in time and are not valid indefinitely. [It was sufficient that] [t]he [buyer] proved to the satisfaction of the [trial] referee that he could have obtained a mortgage commitment at any time...." [Citations omitted; emphasis omitted.]). Accordingly, we reject the defendant's contention that the evidence was insufficient to support the trial court's finding that the plaintiff was ready, willing and able to effectuate the purchase of the properties when the plaintiff sought to exercise its purchase options.

The judgment of the Appellate Court is reversed and the case is remanded to that court with direction to affirm the judgments of the trial court.

In this opinion ROGERS, C.J., and NORCOTT, EVELEIGH, McDONALD and VERTEFEUILLE, Js., concurred.

ZARELLA, J., dissenting.

I agree with the majority that an optionee must express his election to accept an option in strict accordance with its terms and conditions. I do not agree, however, that there should be a different compliance standard applied to other conditions precedent to the optionor's duty to perform. Many option contracts contain conditions relating to the form of acceptance, such as requiring notice in writing within a specified period of time. Other options provide additional conditions that the optionee must satisfy prior to exercising the option, such as compliance with the terms of a lease. All of these conditions are, in effect, part of the performance that the optionee must complete in order to accept the offer. In my view, if strict compliance applies to some conditions, it should apply to all conditions, both from a commonsense perspective and in light of this court's decision in Brauer v. Freccia, 159 Conn. 289, 268 A.2d 645 (1970), which requires an optionee to fully comply with all "named conditions...." Id., at 294, 268 A.2d 645. This is especially true when, as in the present case, the option is part of a commercial transaction between sophisticated parties. I finally observe that the application of the doctrine of substantial performance to unilateral contracts is inappropriate because it protects rights that optionees do not yet possess. Accordingly, I respectfully dissent.

I begin with the applicable law regarding option contracts and conditions precedent. "A unilateral contract is one in which the offeror invites acceptance of his promise not by a reciprocal promise, but by performance .... [I]n such a contract, there is no mutuality of obligation between the parties. See generally 1 E. Farnsworth, [Farnsworth on] Contracts (1990) § 3.24 [pp. 290-91]...." (Citation omitted; emphasis added.) Torosyan v. Boehringer Ingelheim Pharmaceuticals, Inc., 234 Conn. 1, 13 n. 4, 662 A.2d 89 (1995). Option contracts are a type of unilateral contract. See, e.g., Williams v. Lilley, 67 Conn. 50, 56, 34 A. 765 (1895). An option to purchase real estate, therefore, is "a continuing offer to sell, irrevocable until the expiration of the time period fixed by agreement of the parties, which creates in the option holder the power to form a binding contract by accepting the offer." (Internal quotation marks omitted.) Bayer v. Showmotion, Inc., 292 Conn. 381, 409, 973 A.2d 1229 (2009). The optionee may accept this offer and form a binding, bilateral contract of sale through performance "according to the precise terms and conditions of the contract." (Emphasis added; internal quotation marks omitted.) Pigeon v. Hatheway, 156 Conn. 175, 183, 239 A.2d 523 (1968).

Thus, "[t]he offeror's duty of performance under any option contract so created is conditional on completion or tender of the invited performance in accordance with the terms of the offer." (Emphasis added.) 1 Restatement (Second), Contracts § 45(2), p. 118 (1981).1 Put another way, in order to convert the unilateral option contract into a binding, bilateral contract for sale, the optionee must "[accept] the offer according to its terms ... [by] perform[ing] the conditions contained in the offer." Buchannon v. Billings, 127 Vt. 69, 74, 238 A.2d 638 (1968); see also Brauer v. Freccia, supra, 159 Conn. at 293-94, 268 A.2d 645 ("[The] language [of the option] clearly indicates that the [lessor's] duty to comply with the terms of the option was conditioned [on] the [lessees'] punctual performance of their obligations under the lease. A [lessee] who fails to meet the named conditions of his lease defeats his right to rely on it when he makes an effort to purchase the property pursuant to the option in the lease." [Emphasis added.]).2

I see no logical reason to apply different compliance standards to different conditions precedent in an option contract when determining whether a party has complied with the conditions of the contract.3 Option contracts may contain numerous conditions precedent. For example, some option contracts provide that the optionee must communicate his election to accept the option in a certain way, such as providing written notice within a specified period of time.4 Other option contracts, such as the one at issue in the present case, impose additional conditions precedent, such as compliance with the terms of a lease.5 At times, a condition precedent might be outside the control of the parties.6 Often, however, the condition is entirely within the control of the optionee, such as ensuring that the terms of a lease are satisfied. Because conditions precedent within the control of the optionee must be satisfied by the optionee, the satisfaction of these conditions is the "performance" that constitutes the "acceptance" of the offer so as to trigger the optionor's obligation to perform.

Our precedent does not distinguish between various types of conditions precedent.7 In Brauer v. Freccia, supra, 159 Conn. at 291, 268 A.2d 645, the lessees and the lessor entered into a lease on August 28, 1962, providing that, "if the [l]essees shall have duly and punctually fulfilled all of the provisions, agreements, covenants and conditions of this lease ... the [l]essor, on the receipt of written notice from the [l]essees stating that the [l]essees elect to purchase the leased premises ... will convey the leased premises to the lessees on and subject to [certain] conditions [including the following].... It is agreed that this option to purchase may be exercised only by the [l]essees giving the written notice to the [l]essor above provided for at least sixty ... days prior to the expiration of this lease or any renewal thereof." (Internal quotation marks omitted.) Id., at 291 n. 1, 268 A.2d 645. "As of April 1, 1967, [the lessees] had failed to make seven monthly payments of $350 each, causing an arrearage of $2450. As of the date of the trial they had failed to make a further monthly payment of $350 thereby causing a total arrearage of $2800." Id., at 292, 268 A.2d 645. On April 18, 1967, the lessees provided written notice to the lessor, "stating that they wished to purchase the property under the terms of the option." Id. The lessor then "caused a notice to quit to be served on the [lessees], claiming nonpayment of rent." Id.

This court determined that "the language [of the option was] lucid and unambiguous in stating that the [lessor] ... was obligated under the option clause `if the [l]essees shall have duly and punctually fulfilled all the provisions, agreements, covenants and conditions of [the] lease.' This language clearly indicate[d] that the [lessor's] duty to comply with the terms of the option was conditioned [on] the [lessees'] punctual performance of their obligations under the lease. A [lessee] who fails to meet the named conditions of his lease defeats his right to rely on it when he makes an effort to purchase the property pursuant to the option in the lease. Lake Shore Country Club v. Brand, 339 Ill. 504, 522, 171 N.E. 494 [(1930)]." (Emphasis added.) Brauer v. Freccia, supra, 159 Conn. at 293-94, 268 A.2d 645. Accordingly, the court concluded that, because "the [lessees] had failed to perform their obligations under the lease, the right to enforce the option to purchase was not in existence and the [lessor was] under no obligation to convey the property." Id., at 294, 268 A.2d 645.

The majority posits that the lessees' breach in Brauer was "material" and thus assumes that "there is nothing in Brauer to suggest that a nonmaterial breach of the lease also would have defeated the option rights of the lessees in that case." Text accompanying footnote 9 of the majority opinion. I disagree. First, the language in Brauer is broad, referring to "named conditions" of the lease without distinguishing between material and immaterial terms. Brauer v. Freccia, supra, 159 Conn. at 294, 268 A.2d 645. Second, there is no reason for the court to have engaged in a materiality analysis, as the material versus immaterial distinction derives from the doctrine of substantial performance, not the law of unilateral contracts and options in this state. Third, in light of the facts of the present case, even if it is assumed that materiality is the proper test, which it is not, the breaches in the present case are clearly material, and, thus, even the standard of substantial performance has not been satisfied.

The doctrine of substantial performance, in my view, should not be extended to unilateral contracts. "[This] doctrine is generally applicable to bilateral contracts for an agreed exchange of performances." (Emphasis added.) J. Calamari & J. Perillo, The Law of Contracts (4th Ed. 1998) § 11.18(b), p. 417. That is, "[t]he doctrine of substantial performance ... is generally only applicable to contractual provisions in which a party is affirmatively obligated to perform. See generally 3A A. Corbin, [Corbin on] Contracts [1960] §§ 700-701 [pp. 308-15]; 6 [W. Jaeger, Williston on] Contracts (3d Ed. [1962]) § 842 [pp. 165-71]." (Emphasis added.) Analytical Design & Construction Group, Inc. v. Murray, 690 P.2d 269, 272 (Colo.App.1984). "Consequently, the doctrine of substantial performance is not applicable to a unilateral [agreement] ...." (Emphasis added.) Id., at 273.8

The application of the substantial performance doctrine to unilateral contracts prematurely grants optionees rights that have not yet vested. "The doctrine is intended to protect the right to [performance] of those who have performed in all material and substantive particulars, so that their right to [performance] may not be forfeited by reason of mere technical, inadvertent, or unimportant omissions or defects." (Internal quotation marks omitted.) In re Centennial Park, LLC, 461 B.R. 853, 863 (Bankr.D.Kan.2011). In a unilateral contract, however, the optionee does not have a right to exercise the option, let alone a right to performance, until the optionee has accepted the offer through performance of the named conditions. Therefore, application of the doctrine of substantial performance in this context provides the optionee with rights that he simply does not have.9 It also strips the optionor of the benefits of his bargain, as conditions precedent often are part of the consideration for the option itself. Finally, it deprives both parties of a degree of economic certainty that is particularly beneficial in a commercial context. See Loitherstein v. International Business Machines Corp., 11 Mass.App. 91, 94, 413 N.E.2d 1146 (1980) ("holding the possessor of a unilateral right of this sort to literal compliance with the requirements for its exercise enforces commercial certainty"). Accordingly, I conclude that the optionee must perform all conditions in strict accordance with their terms.

Turning to the issue in the present case, I conclude that the plaintiff, Pack 2000, Inc., did not strictly comply with the terms of the lease agreements, letter of intent, and management agreement and, thus, is not entitled to specific performance. The options at issue provided in relevant part: "So long as [the plaintiff] has been in compliance with the terms and conditions of [the] Lease, the Letter of Intent, and [the] Management Agreement... and is in compliance with such instruments when the option is exercised, [the plaintiff] shall have the option to purchase the real estate subject of this lease."10 The trial court found, pursuant to the terms of the lease agreements, letter of intent, and management agreement, that the "[p]laintiff was required to make periodic payments to [the defendant, Eugene C. Cushman] and to third parties" and that the "[p]laintiff was sometimes late in making... payments and [that the defendant] frequently contacted [the] plaintiff regarding these late payments."11 Because the language of the options required compliance not only at the time of exercise, but also at all times prior thereto, the plaintiff forfeited its right to exercise the options as soon as it made a late payment,12 even though it was not in arrears at the time of trial.13 Therefore, because the plaintiff in the present case "fail[ed] to meet the named conditions of [its] lease[s]," the plaintiff "defeat[ed] [its] right to rely on [the options] when [it made] an effort to purchase the property pursuant to the option[s] in the lease[s]." Brauer v. Freccia, supra, 159 Conn. at 294, 268 A.2d 645.

I am particularly concerned that the majority's substantial performance analysis rewrites the options. Under a logical extension of the majority's construction, the plaintiff would have to be in compliance with the lease agreements, letter of intent, and management agreement only at the time it exercises the options. That is, the plaintiff would be able to cure its prior noncompliance by settling any arrearages before exercising the options. The options, however, required that the plaintiff "has been in compliance ... and is in compliance ... when the option[s] [are] exercised...." (Emphasis added.) This language signifies that past noncompliance cannot be cured, at least not by the optionee.14

Finally, I emphasize that the agreements between the plaintiff and the defendant constituted a commercial transaction between two sophisticated parties, both of whom contributed to the drafting of these contracts and previously participated in similar transactions. Thus, there is even less reason for the majority to insert itself into the contract and change its terms. The plaintiff's vice president, M. Paulina Anderson, testified that she provided the letter of intent and management agreement, and negotiated with the defendant to modify both documents. The defendant's testimony corroborates the fact that both parties actively participated in the negotiation and ultimate drafting of these documents. Furthermore, Anderson appears to have extensive experience in the acquisition of Midas automobile repair shops, as she testified to having assisted in the acquisition of thirty-two such shops since 1991. In the present case, the language of the agreements indicates that the timely payment of financial obligations was the only consideration the defendant would have received for entering into the option contracts. The defendant testified that "it was very, very important that everything [got] paid ... on time" because the defendant "had to make payments from [the plaintiff's] payments," and, "if [he, the defendant] didn't make the payments... to Midas ... Midas could pull the franchise.... If [he, the defendant] didn't make the payment for [his] mortgage [he] was going to lose the real estate." Furthermore, any late payment or nonpayment of the plaintiff's health insurance obligations would "jeopardiz[e] all of [the defendant's] health insurance." Because the timeliness of these payments was so important, the defendant "made it perfectly clear to [the plaintiff]" that compliance with the terms of the lease agreements, letter of intent, and management agreement was necessary by including this condition in the options.

The defendant, however, did not get the benefit of his bargain, as the plaintiff consistently made late payments on many of its obligations, or, at times, did not make payments at all. Specifically, the Appellate Court observed: "[T]he record reveals that the following payments were late: the rent payment due on May 1, 2004; three payments on the promissory notes due on February 8, 2003, and May 8 and June 8, 2006; one payment to Groton Utilities, which resulted in a shutoff notice that the defendant forwarded to the plaintiff on January 23, 2003; several payments to a telephone company, which resulted in several collection letters and telephone calls that the defendant received in late 2002 and early 2003 as well as a threat to terminate telephone service to the defendant's unrelated business in March, 2003; two real estate tax installments on the New London [Midas] shop due January 1, 2005, and January 1, 2007; one real estate tax installment on the Groton [Midas] shop due July 1, 2007; twelve hazard and liability insurance installments between November, 2002, and January, 2004, that resulted in cancellation notices issued on July 30, 2003, and November 29, 2004; twenty health insurance installments between October, 2002, and September, 2005; and several installments under the terms of an equipment lease that resulted in several collection calls to the defendant in 2002 and 2003." Pack 2000, Inc. v. Cushman, 126 Conn.App. 339, 343-44, 11 A.3d 181 (2011). The majority's construction of the contract thus forces the defendant to comply with an agreement to which he did not agree.

In sum, strict compliance should apply to all conditions of an option contract, not just those relating to the election to accept the offer. In addition, in the context of an option to purchase real estate, I would conclude that "[t]here is no completed contract for sale of the property described in an option until the optionee has accepted the offer according to its terms, or to put it otherwise, has performed the conditions contained in the offer." (Emphasis added.) Buchannon v. Billings, supra, 127 Vt. at 74, 238 A.2d 638; see also Howard-Arnold, Inc. v. T.N.T. Realty, Inc., 145 Conn.App. 696, 710, 77 A.3d 165 ("[o]ptions... require optionees to exercise them in strict compliance with their terms"), cert. granted, 310 Conn. 940, 940-41, 79 A.3d 892 (2013). Because I would uphold the judgment of the Appellate Court but direct that court to remand the case to the trial court for a determination of whether the defendant waived the plaintiff's noncompliance; see footnote 13 of this opinion; I respectfully dissent.
