MEMORANDUM & ORDER
GORTON, District Judge.Plaintiff Karen Arcieri (“Arcieri”) alleges that defendant New York Life Insurance Company (“New York Life”) breached the terms of a life insurance policy by 1) improperly amending the designation of the beneficiaries of the policy without her consent or knowledge and 2) distributing the proceeds in accordance with that amendment.
Pending before the Court is defendant’s motion to dismiss or, in the alternative, for summary judgment. For the reasons that follow, the motion to dismiss will be allowed.
I. Background
New York Life issued two policies insuring the life of the plaintiffs late husband, Vincent A. Arcieri, III. Policy No. 44384504, dated November 11, 1991, provided whole life coverage in the amount of $500,000 and $500,000 of term coverage under an increasing premium term rider (“Policy A”). At the time it issued, plaintiff was the owner and sole beneficiary of Policy A. The New York Life agent assigned to Policy A was Thomas Chevalier (“Chevalier”), who worked for the company between 1991 and 1993.
In January, 1992, New York Life recorded a change in beneficiary such that the plaintiffs beneficial interest in Policy A was reduced to 50% and her father-in-law, Vincent Arcieri Jr. (“father-in-law”), was named the other 50% beneficiary. New York Life requires a Change of Beneficiary form signed by the policy owner in order to change a beneficiary on a policy.
*162Chevalier recalled, during his deposition in a prior lawsuit filed by plaintiff in state court against the executors of the father-in-law’s estate, that the plaintiffs late husband requested the beneficiary change. He did not remember whether it was the plaintiff or her late husband who signed the required form. Chevalier testified, however, that someone must have signed the form because he would not have processed it otherwise. Plaintiff, on the other hand, asserts that the change of beneficiary was effected without her knowledge or consent. New York Life has been unable to locate the relevant paperwork either to rebut or to confirm her assertion.
In October, 1992, plaintiff submitted an application to convert the $500,000 term rider on Policy A into a separate $500,000 whole life policy. The rider was thus converted into Policy No. 44711438 (“Policy B”). Under Policy B, the plaintiffs infant daughter was a 50% beneficiary and the plaintiff and her father-in-law were each 25% beneficiaries.
Upon the death of the plaintiffs late husband in December, 1992, plaintiff and her father-in-law apparently entered into an oral agreement with respect to both policies under which the father-in-law promised to hold $375,000 of the life insurance proceeds (his entire beneficial interest under both policies) for the benefit of plaintiff and her daughter until her daughter’s 18th birthday. Plaintiff alleges that she requested New York Life to disburse the funds in accordance with her agreement with her father-in-law.
Consistent with the recorded beneficiary designation and plaintiffs alleged request, New York Life paid out the full amount due under Policy A in February, 1993 (which included some interest). Plaintiff and her father-in-law each received $252,539. New York Life also paid out proceeds under Policy B, whereby plaintiff and her father-in-law each received- their 25% shares, or $126,590. Although it is unstated, the remainder of the proceeds of Policy B was presumably held in trust for the benefit of plaintiffs daughter. Plaintiff makes no claim with respect to Policy B in this case.
Apparently, plaintiffs daughter had not reached age 18 when the father-in-law died in 2008. He had not yet paid the money he allegedly promised to hold on his granddaughter’s behalf prior to his death. In April, 2009, plaintiff filed suit in Massachusetts Superior Court for Middlesex County against the executors of her father-in-law’s estate,' seeking recovery of $375,000 in life insurance proceeds. Plaintiff voluntarily dismissed that action in May, 2012.
II. Procedural history
Arcieri filed her complaint against New York Life in the same Middlesex Superior Court in April, 2014. Defendant timely removed that case to this Court and moved to dismiss it or, in the alternative, for summary judgment in May, 2014. Plaintiff subsequently filed a motion for leave to amend her complaint to join Chevalier as an additional defendant, which would have extinguished this Court’s diversity jurisdiction and necessitated a remand to state court. This Court denied that motion by endorsement in July, 2014.
III. Defendant’s motion to dismiss or, in the alternative, for summary judgment
Plaintiff asserts claims against New York Life for breach of contract, breach of fiduciary duty and negligence and for violations of Massachusetts General Laws, Chapters' 175, 176 and 93A. Defendant has moved to dismiss or, in the alternative, for summary judgment in response.
*163A. Legal standard
Federal Rule of Civil Procedure 12(d) provides that if
matters outside the pleadings are presented to and not excluded by the court, the motion shall be treated as one for summary judgment and disposed of as provided in Rule 56.
Here, both parties have submitted materials beyond the complaint and its exhibits, such as documents associated with the plaintiffs suit against her father-in-law’s ■estate for breach of contract filed in state court and an affidavit of the plaintiff dated July 21, 2014.
Filing additional materials outside the pleadings does not automatically convert a motion to dismiss into one for summary judgment. Garita Hotel Ltd. P’ship v. Ponce Fed. Bank, F.S.B., 958 F.2d 15, 18 (1st Cir.1992). The decision whether to exclude the materials and determine the motion under the Rule 12(b)(6) standard is within the Court’s discretion. Trans-Spec Truck Serv., Inc. v. Caterpillar Inc., 524 F.3d 315, 321 (1st Cir.2008). In this case, the Court chooses to treat defendant’s motion as a motion to dismiss.
To survive a motion to dismiss, a complaint must contain sufficient factual matter, accepted as true, to “state a claim to relief that is plausible on its face.” Bell Atl. Corp. v. Twombly, 550 U.S. 544, 570, 127 S.Ct. 1955, 167 L.Ed.2d 929 (2007). Exhibits attached to the complaint are properly considered “part of the pleading for all purposes.” Fed.R.Civ.P. 10(c). In considering the merits of a motion to dismiss, the Court must accept all factual allegations in the complaint as true and draw all reasonable inferences in the plaintiffs favor. Langadinos v. Am. Airlines, Inc., 199 F.3d 68, 69 (1st Cir.2000). Yet “[tjhreadbare recitals of the elements of a cause of action, supported by mere conclu-sory statements,” do not suffice to state a cause of action. Ashcroft v. Iqbal, 556 U.S. 662, 678, 129 S.Ct. 1937, 173 L.Ed.2d 868 (2009). Accordingly, a complaint does not state a claim for relief where the wellpled facts fail to warrant an inference of anything more than the mere possibility of misconduct. Id. at 679, 129 S.Ct. 1937.
B. Application
1. M.G.L. c. 175 § 123 and M.G.L. c. 176D (Counts IY and V)
As a preliminary matter, plaintiff has no private - cause of action under M.G.L. c. 175, § 123 or M.G.L. c. 176D because the Commissioner of Insurance has exclusive authority to enforce those statutes. M.G.L. c. 175, § 3A; M.G.L. c. 176D §§ 6, 7; see also Thorpe v. Mut. of Omaha Ins. Co., 984 F.2d 541, 544 n. 1 (1st Cir.1993). Accordingly, Counts IV and V of plaintiffs complaint will be dismissed.
2. Statute of limitations
New York Life contends that all of the claims set forth by the plaintiff should be dismissed as time-barred. A defendant can raise the statute of limitations as an affirmative defense in a Rule 12(b)(6) motion to dismiss so long as the underlying factual basis for the defense is “clear on the face of the plaintiffs pleadings.”. Santana-Castro v. Toledo-Davila, 579 F.3d 109, 113-14 (1st Cir.2009) (citation omitted). As the First Circuit Court' of Appeals recently held
[w]hen the allegations in a complaint show that the passage of time between the. events giving rise to the claim and the commencement of the action exceeds the applicable limitations period, a [ ] court should grant a 12(b)(6) motion by the defense if the complaint (and any other properly considered documents) fails to sketch a factual' predicate that *164would provide a basis for tolling the statute of limitations.
Abdallah v. Bain Capital LLC, 752 F.3d 114, 119 (1st Cir.2014) (internal quotations omitted).
Tort claims, claims brought under Chapter 93A and breach of contract claims must be commenced within three, four and six years, respectively, after the causes of action accrue. M.G.L. c. 260 §§ 2, 2A, 5A. Causes of action in contract and tort generally accrue at the time of breach or injury. See Int’l Mobiles Corp. v. Corroon & Black/Fairfield & Ellis, Inc., 29 Mass. App.Ct. 215, 221, 560 N.E.2d 122 (1990). For the plaintiff, this occurred at the latest in February, 1993, when New York Life paid out the full amount of proceeds due under Policies A and B.
The statute of limitations may be tolled, however, when 1) the facts giving rise to a cause of action are “inherently unknowable” to the injured party or 2) when a cause of action is fraudulently concealed by the wrongdoer. Gonzalez v. United States, 284 F.3d 281, 288-89 (1st Cir.2002).
a. Inherently unknowable
Tolling takes effect pursuant to the discovery rule if the factual basis for the cause of action must have been “inherently unknowable” at the time of injury. Gonzalez, 284 F.3d at 288-89. The factual basis fór a cause of action is “inherently unknowable” if it is “incapable of detection by the wronged party through the exercise of reasonable diligence.” Geo. Knight & Co., Inc. v. Watson Wyatt & Co., 170 F.3d 210, 213 (1st Cir.1999) (citation and internal quotations omitted). The “inherently unknowable” standard is “no different from, and is used interchangeably with, the “knew or should have known” standard.” Williams v. Ely, 423 Mass. 467, n. 7, 668 N.E.2d 799 (1996).
Areieri contends that she could not have learned of the change of beneficiary due to her emotional state upon the death of her husband and her reasonable reliance upon Chevalier, the defendant and her father-in-law. Although she acknowledges being aware that her father-in-law received a disbursement from Policy A, plaintiff alleges that she believed that he received it pursuant to their agreement rather than as a 50% beneficiary. She claims to have first learned of the change in beneficiaries in 2011, after discovery began in her earlier lawsuit against her father-in-law.
The factual allegations in the complaint indicate that the only reason plaintiff did not learn of the change of beneficiary at the time the policy proceeds were disbursed in 1993 was because she apparently had made an oral agreement with her father-in-law and requested that New York Life distribute the proceeds of Policy A accordingly. Had she not given such an instruction, plaintiff presumably would have noticed that one-half of the Policy A proceeds were, in her eyes, wrongfully distributed. In any event, if plaintiff had questions regarding the terms and/or beneficiaries of Policy A, in the exercise of reasonable diligence, she should have asked New York Life during or after the time of the disbursement of policy proceeds.
The facts alleged in the pleadings therefore do not support a finding that plaintiffs causes of action against New York Life were “inherently unknowable.”
b. Fraudulent concealment
A statute of limitations may also be tolled if a wrongdoer “conceal[s] the existence of a cause of action through some affirmative act done with intent to deceive.” Puritan Med. Ctr., Inc. v. Cash-*165man, 413 Mass: 167, 175, 596 N.E.2d 1004 (1992). Mere “silence in subsequent dealings between the parties does not amount to fraudulent concealment”. Szymanski v. Bos. Mut. Life Ins. Co., 56 Mass.App.Ct. 367, 381, 778 N.E.2d 16 (2002). There must be a requisite affirmative act. Id.
The plaintiff has not alleged that Chevalier or anyone else at New York Life affirmatively acted with an intention to deceive her. At worst, New York Life was silent on the issue of the change in beneficiary and silence is insufficient to rise to the level of deception. See id. . Plaintiffs claims therefore cannot be tolled due to fraudulent concealment.
Although the Court perceives a heartless, intra-family fraud perpetuated against a naive but sympathetic widow, it can provide no remedy. The Court concludes that plaintiffs claims against New York Life for breach of contract, breach of fiduciary duty, negligence and violation of M.G.L. c. 93A are barred by the statute of limitations as a matter of law. Accordingly, the remaining Counts of the complaint will be dismissed.
ORDER
For the foregoing reasons, defendant’s motion to dismiss (Docket No. 11) is ALLOWED.
So ordered.
