Herbert Berezin appeals from the judgment of the district court dismissing his complaint against Regency Savings Bank (“Regency”). Claiming that an error in a promissory note’s recitation of the interest rate resulted in overpayments, Berezin seeks to recover nearly $1 million in interest payments he made to Regency. The district court granted Regency’s motion to dismiss under Federal Rule of Civil Procedure 12(b)(6), ruling that the “clear and unambiguous” terms of the promissory note precluded consideration of any contrary terms in the commitment letter relied upon by Berezin. Because we conclude that Massachusetts law permits the consideration of extrinsic evidence when one party to a contract alleges a mutual mistake in its terms, we vacate the judgment of the district court.
I. Background
We may affirm a dismissal for failure to state a claim “only if it clearly appears, according to the facts alleged, that the plaintiff cannot recover on any viable theory.” Cor
rea-Martinez v. Arrillaga-Belendez,
The original parties to this transaction, Herbert Berezin, as general partner of Riverplace Apartments Limited Partnership, and Bank of New England (“BNE”), signed a commitment letter on February 8, 1988 for a $4.5 million loan to finance the Partnership’s acquisition and renovation of properties for low and moderate income housing. They executed a note for the loan on March 11. BNE sold the note to Fleet Bank in 1991, and Fleet sold the note to the defendant in this action, Regency Savings Bank (“Regency”), in February, 1998. The commitment letter of February 8 recites that, after three years, the rate of interest on the loan would be the interest rate of three-year United States Treasury notes, plus 2.5 percent. Significantly, the commitment letter does not provide for a minimum interest rate. The promissory note, however, specifies that the interest rate will not drop below ten percent.
On August 1, 1992, the interest rate for three-year Treasury notes fell below 7.5 percent for the first time since the execution of the note, dropping to 7.47 percent. Under the terms of the commitment letter, Berezin would have been entitled to an interest rate of 9.97 percent at that time. However, according to the terms of the promissory note — setting the interest rate at a minimum of ten percent — Berezin continued to pay ten percent interest on the loan. He alleges that this provision in the note is in error, and that he has paid excess interest “of at least $972,636.00” because of this mistake.
During the time that it owned the note, Fleet Bank brought two errors to Berez-in’s attention: one involved an alleged mistake in the maturity date, while the other involved the omission of a demand provision that had been in the commitment letter but was not contained in the note. In both instances, Berezin agreed to a written modification to the note to reflect the terms of the commitment letter and the understanding of both parties. Berez-in proffers these written modifications as evidence that other mistakes existed in the executed note, comparable to the interest rate error.
In support of its motion to dismiss pursuant to Rule 12(b)(6), Regency argued that the interest rate provision of the note was unambiguous on its face and the parol evidence rule barred the consideration of extrinsic evidence, including the terms of the commitment letter, to establish the rate. Regency claimed, in the alternative, that Berezin’s claim was time-barred.
*71 Following a hearing, the district court granted Regency’s motion to dismiss. Because the court found for Regency on the application of the parol evidence rule, it did not reach the issue of whether the statute of limitations bars Berezin’s claim. We conclude that Berezin’s claim of mutual mistake survives a motion to dismiss, and that his claim is not barred by the statute of limitations.
II. Mutual Mistake
We begin with Berezin’s allegation in his complaint that the promissory note reflects a mutual mistake of the parties with respect to the interest rate. Paragraph six of his complaint states:
The note contained a significant error and discrepancy from the commitment letter in that it did not clearly make it known that the interest rate on the loan would go below ten percent per annum and in fact that the interest rate was required to be adjusted to below 10% to a rate 2.5 percent per annum above the three year Treasury Note rate with no ten percent minimum rate.
(Emphasis added). Berezin also described the two other mistakes in the note, brought to his attention by Fleet, and modified by written agreement to reflect the terms specified in the commitment letter. Paragraph 11 of his complaint quotes from a letter written to Berezin by Fleet about one of those discrepancies, in which Fleet noted that certain language “was unintentionally omitted from the promissory note.” Additionally, the complaint avers that Berezin did not become aware of the alleged error in the interest rate until July, 1999. In his memorandum in opposition to Regency’s motion to dismiss, Berez-in reiterated these allegations, claiming that, “[unintentionally and without agreement of the parties, the terms of the note differed from the terms of the commitment letter.” Berezin has continued to articulate this theory of mutual mistake on appeal, claiming in his brief that the note contained “a significant error and discrepancy.”
In granting Regency’s motion to dismiss the complaint, the district court invoked the familiar precept that the parol evidence rule bars consideration of extrinsic evidence to contradict the terms of an unambiguous, fully-integrated written instrument.
See, e.g., ITT Corp. v. LTX Corp.,
In summary, to countenance plaintiffs complaint the court would have to ignore the parol evidence rule. The controlling document in this case is the note signed by the plaintiff and the defendant’s predecessor in interest. Plaintiff simply cannot rely on an inconsistent prior written communication — -here, the commitment letter — to alter the terms of the note. Since the terms of the note are clear and unambiguous, they control and require dismissal of plaintiffs lawsuit.
In part, perhaps, because Berezin’s complaint does not identify by name his theory of “mutual mistake,” the district court’s ruling overlooks the possibility that the promissory note could be reformed if Berezin provided sufficient evidence that the parties had made a mistake in the note’s description of the interest rate. Nonetheless, we must accept all of the facts in the complaint as true, and indulge all reasonable inferences in Berezin’s favor.
See Langadinos,
Massachusetts law permits reformation of written contracts where one party has alleged a mutual mistake in the terms of the agreement.
“If
the language of a written instrument does not reflect the true intent of both parties, the mutual mistake is reformable.”
Polaroid Corp. v. Travelers Indemnity Co.,
Nonetheless, mindful of the parol evidence rule, which “bars the introduction of prior or contemporaneous written or oral agreements that contradict, vary, or broaden an integrated writing,”
Kobayashi v. Orion Ventures, Inc.,
In summary, given the allegations in the complaint, and the applicable Massachusetts law, we cannot conclude that “it clearly appears, according to the facts alleged, that the plaintiff cannot recover on any viable theory.”

*73 III. The Statute of Limitations
The district coürt declined to rule on Regency’s statute of limitations argument because it found the parol evidence rule dispositive in dismissing Berezin’s complaint. Having determined that Berezin’s complaint is not barred by the parol evidence rule, we must decide whether Berezin’s claim is barred by the statute of limitations. We conclude that Berezin’s suit is not time-barred.
The statute of limitations in an action for breach of contract in Massachusetts is six years.
See
Mass. Gen. Laws, ch. 260 § 2;
see also City of New Bedford v. Lloyd Investment Assoc., Inc.,
The promissory note provides that the interest and principal shall be payable on a monthly basis. Massachusetts courts have characterized such agreements as installment contracts.
See, e.g., Clark,
Judgment vacated. Remanded for further proceedings.
Notes
. The district court was concerned that Ber-ezin was asking for a ruling that the commitment letter itself, and not the promissory note, was the binding legal document between the parties. The court stated at the hearing on the motion to dismiss: “I don't understand how you can go back to the commitment letter and attempt to enforce the commitment letter as an independent contract.” In fact, however, the commitment letter would simply be part of the extrinsic evidence proffered by Berezin to substantiate his allegation of mutual mistake.
. Because Regency did not make the argument in its motion to dismiss or on appeal, we do not consider the effect on plaintiff's mutual mistake claim of any special status that Regency may have as the second purchaser of the note. See, e.g., Restatement (Second) of Contracts, § 155 cmt. f ("The claim of a mistaken party to reformation, being equitable in its origin, is subject to the rights of good faith purchasers for value and other third parties who have similarly relied on the finality of a consensual transaction in which they have acquired an interest in property.”).
. As an alternative to his theory that the promissory note is an installment contract, and as a basis for even avoiding the six-year statute of limitations period, Berezin argues that his claim is timely pursuant to Mass. Gen. Laws ch. 260, § 36. That provision allows a defendant to file a compulsory counterclaim for recoupment without regard to the statute of limitations. However, § 36 is plainly not applicable to the instant situation because Berezin is not filing a compulsory counterclaim in response to an action initiated by Regency. Berezin has provided no authority for the proposition that § 36 is a proper basis for disregarding or extending the statute of limitations in these circumstances, where Berezin is the plaintiff and there was no initial claim filed by Regency. Indeed, as we have noted, recoupment, which is the essence of a counterclaim pursuant to § 36, is "in the nature of a defense." United Structures of America, Inc. v. G.R.G. Eng'g, S.E., 9 F.3d 996, 999 (1st Cir.1993). Therefore, § 36 is not properly asserted by a plaintiff as authority for avoiding the statute of limitations.
