    GANTS, C.J.    Under Federal law, a manufacturer of a generic
    drug must provide its users with a warning label that is
    identical to the label of the brand-name counterpart.   See
    PLIVA, Inc. v. Mensing, 
    564 U.S. 604
    , 613 (2011) (PLIVA).     The
    issue on appeal is whether a plaintiff who alleges that he was
    injured from his use of a generic drug, because of a failure to
    warn of the drug's side effects, may bring a common-law general
    negligence claim and a statutory claim under G. L. c. 93A
    against the brand-name drug manufacturer that created the
    warning label.   Applying our general principles of tort law and
    as a matter of public policy, we conclude that the plaintiff may
    not bring a negligence claim against the brand-name manufacturer
    for a failure to warn.   We further conclude that the plaintiff,
    if he were to amend his complaint, and if the amended
    allegations would so warrant, may bring a common-law
    recklessness claim against the brand-name manufacturer if it
    intentionally failed to update the label on its drug, knowing or
    having reason to know of an unreasonable risk of death or grave
    3
    bodily injury associated with its use.    We also conclude that a
    plaintiff who is injured by a generic drug due to a failure to
    warn cannot bring a claim under G. L. c. 93A, § 9, against a
    brand-name manufacturer that did not advertise, offer to sell,
    or sell that drug because such failure did not occur in the
    conduct of "trade or commerce" as defined in § 1 (b).2
    Background.   1.   Regulatory background.   Under the Federal
    Food, Drug, and Cosmetic Act (act), 21 U.S.C. §§ 301 et seq.
    (2012), drug manufacturers may not market drugs in interstate
    commerce without the approval of the United States Food and Drug
    Administration (FDA).   21 U.S.C. § 355(a).   As such, a
    manufacturer that seeks to market a new brand-name drug must
    submit a new drug application, showing that the drug is safe and
    effective.   See 21 U.S.C. § 355(b)(1); 21 C.F.R.
    § 314.50(d)(5)(iv)-(vi) (2017).   As part of the new drug
    application, the manufacturer must also show that the proposed
    warning label for the drug is accurate and adequate.       See 21
    U.S.C. § 355(b)(1), (d); 21 C.F.R. § 314.50(c)(2)(i), (d)(5)(v),
    (d)(5)(viii) (2017).    The process of obtaining FDA approval is

    "both onerous and lengthy," requiring manufacturers to expend
    significant time and resources.    Mutual Pharm. Co., v. Bartlett,
    
    570 U.S. 472
    , 476 (2013).
    Originally, the same process was required for generic
    drugs.   See 
    PLIVA, 564 U.S. at 612
    .    This changed in 1984, when
    Congress enacted the Drug Price Competition and Patent Term
    Restoration Act, commonly known as the Hatch-Waxman amendments
    to the act.   See 
    id. The purpose
    of the amendments was twofold:
    to improve the affordability of prescription drugs while also
    encouraging innovation and investment in new drugs.     See Abbott
    Labs. v. Young, 
    920 F.2d 984
    , 985 (D.C. Cir. 1990), cert.
    denied, 
    502 U.S. 819
    (1991), citing H.R. Rep. No. 98-857, 98th
    Cong., 2nd Sess., pt. 1, at 14-15 (1984), reprinted in 1984
    U.S.C.C.A.N. 2647, 2648 (House Report).     In striking a balance
    between these competing goals, Congress made two significant
    changes to the existing regulatory scheme.
    First, the amendments established a simpler and speedier
    approval process for generic drugs.     See 21 U.S.C. § 355(j).   A
    manufacturer now seeking to market a generic version of an
    approved brand-name drug need only submit an abbreviated new-
    drug application, indicating that the generic drug is equivalent
    to its brand-name counterpart in certain key respects.     21
    U.S.C. § 355(j)(2)(A).    Specifically, the manufacturer must show
    that the proposed generic drug has the same active ingredients,
    5
    route of administration, dosage form, and strength as the
    approved brand-name drug.   21 U.S.C. § 355(j)(2)(A)(ii)-(iii).
    It also must show that the generic drug is "bioequivalent" to
    the brand-name drug, 21 U.S.C. § 355(j)(2)(A)(iv), meaning that
    it has the same rate and extent of absorption.     21 U.S.C.
    § 355(j)(8)(B).   Finally, it must show that the proposed warning
    label for the generic drug is the same as the labeling approved
    for the brand-name drug.    21 U.S.C. § 355(j)(2)(A)(v).     As a
    result, generic manufacturers can bring their drugs to market
    much less expensively and can therefore make these lower-cost
    alternatives more widely available to consumers.    See 
    PLIVA, 564 U.S. at 612
    .
    Second, in order to safeguard the interests of brand-name
    manufacturers and incentivize continued innovation, the
    amendments also authorized the FDA to extend the length of its
    patent terms to offset delays caused by the FDA's regulatory
    review.   See 35 U.S.C. § 156 (2012).   See also House Report,
    supra at 15.   For patents issued after the amendments were
    enacted, patent terms can now be extended for up to five years,
    depending on the length of the review period, thereby allowing
    brand-name manufacturers to enjoy a monopoly over their newly
    developed drugs for a longer period of time.     35 U.S.C.
    § 156(a), (c), (g)(6)(A).
    6
    A key feature of the current regulatory scheme is that it
    imposes different labeling responsibilities on brand-name
    manufacturers and generic manufacturers.      See 
    PLIVA, 564 U.S. at 613
    .       A manufacturer of a brand-name drug must ensure that its
    label is accurate and adequate.      See 21 U.S.C. § 355(b)(1), (d).
    In contrast, a manufacturer of a generic drug must ensure only
    that its label is identical to the label of the brand-name
    counterpart.      See 21 U.S.C. § 355(j)(2)(A)(v), (j)(4)(G).   See
    also 
    PLIVA, supra
    .       Furthermore, although all drug manufacturers
    are required to continue to monitor the safety of their products
    after approval, 21 C.F.R. §§ 314.80, 314.81, 314.98 (2017), only
    brand-name manufacturers have the power to change the contents
    of their labels without FDA approval.      Under FDA regulations, a
    manufacturer may, through a process known as "changes being
    effected," "add or strengthen" a warning on its label by filing
    a simultaneous application with the FDA, without waiting for the
    agency's approval.       21 C.F.R. § 314.70(c)(3), (c)(6)(iii)(A)
    (2017).3      This process is not available to generic manufacturers
    that, pursuant to their "ongoing [F]ederal duty of 'sameness,'"
    The United States Food and Drug Administration (FDA)
    3
    retains the authority to disapprove any labeling changes made
    through the "changes being effected" process, in which case it
    may order the manufacturer to cease distribution of the drug
    with the disapproved label change. See 21 C.F.R.
    § 314.70(c)(3), (7) (2017). See also Wyeth v. Levine, 
    555 U.S. 555
    , 571 (2009).
    7
    may change a label only when necessary to match an updated
    brand-name label or to follow FDA instructions.   
    PLIVA, supra
    at
    613, 614-615.   See 21 C.F.R. § 314.150(b)(10) (2017) (FDA
    approval for generic drug may be withdrawn if label is "no
    longer consistent" with brand-name label).
    This allocation of labeling responsibilities under Federal
    law has proved difficult to reconcile with the duties required
    of generic drug manufacturers under State tort law.    Many
    States, including this one, impose on manufacturers a duty to
    warn consumers of dangers arising from the use of their products
    where the manufacturers know or should have known of the
    dangers.   See 
    PLIVA, 564 U.S. at 611
    ; Mitchell v. Sky Climber,
    Inc., 
    396 Mass. 629
    , 631 (1986).   Under Federal regulations,
    however, manufacturers of generic drugs -- because they lack the
    power to change the warning labels on their products
    unilaterally -- cannot independently fulfil these State law
    duties.    For this reason, in 
    PLIVA, 564 U.S. at 608-609
    , the
    United States Supreme Court held that State tort law claims
    against generic manufacturers arising out of a failure to warn
    are preempted by Federal drug regulations.   See Mutual Pharm.
    
    Co., 570 U.S. at 476
    ("[S]tate-law design-defect claims that
    turn on the adequacy of a drug's warnings are pre-empted by
    [F]ederal law under PLIVA").   The practical consequence is that
    a consumer who suffers injury arising from an inaccurate or
    8
    inadequate drug warning label can sue the manufacturer for
    damages caused by his or her injury only if the consumer
    ingested a brand-name version of the drug -- but not if the
    consumer ingested the generic version.    See 
    PLIVA, supra
    at 625.
    2.   Plaintiff's claims.    We summarize the facts as stated
    in the plaintiff's complaint.   Merck & Co., Inc. (Merck), is the
    manufacturer of Proscar, an FDA-approved, brand-name version of
    the drug finasteride.   Finasteride is used to treat benign
    prostatic hyperplasia in persons with an enlarged prostate.
    In August, 2010, Brian Rafferty was prescribed finasteride
    by his physician to treat an enlarged prostate.   Shortly after
    he started taking finasteride, Rafferty began to experience side
    effects causing sexual dysfunction, including erectile
    dysfunction and decrease in libido.   In October, 2010, Rafferty
    weaned himself off of the drug but the side effects continued
    and even worsened.   He was eventually diagnosed with
    hypogodanism and androgen deficiency allegedly induced by the
    finasteride, and is now undergoing treatment that, according to
    his physicians, may continue indefinitely.
    It is undisputed that Rafferty ingested the generic version
    of finasteride, not Merck's brand-name version Proscar.    At the
    time that Rafferty was prescribed the finasteride, the product
    label warned of the potential for side effects related to sexual
    dysfunction, but represented that these side effects would
    9
    resolve after discontinued use of the drug.     As required under
    Federal law, this generic label conformed to Merck's label for
    Proscar.
    Rafferty alleged that by the time he was prescribed
    finasteride, several reports and studies had already emerged
    suggesting that those side effects could in fact persist even
    after discontinued use.   He also alleged that, starting in 2008,
    Merck changed the label for Proscar in certain foreign markets,
    including Sweden, the United Kingdom, and Italy, to include a
    warning about persistent erectile dysfunction.     Nevertheless, as
    of 2010, when Rafferty ingested finasteride, Merck had not
    changed its label for Proscar in the United States to include
    this warning.
    In 2013, Rafferty commenced an action against Merck in the
    Massachusetts Superior Court, asserting claims of negligence for
    failure to warn, and a violation of G. L. c. 93A, § 9.4    Crucial
    to Rafferty's negligence claim was his contention that, although
    he had never ingested Merck's brand-name version of finasteride,
    Merck nevertheless owed him a duty to warn of its dangers
    because, under Federal law, Merck controlled the label on the
    generic version that Rafferty did ingest.     The case was removed
    4 Rafferty also sued his prescribing physician for negligent
    failure to obtain informed consent. He later voluntarily
    dismissed the claim against the physician.
    10
    to Federal court but subsequently remanded to the Superior
    Court.
    Merck filed a motion to dismiss the complaint, and the
    judge allowed the motion.   With respect to Rafferty's negligence
    claim, the judge ruled that Merck owed no duty of care to
    Rafferty.   The judge relied on "two well-established . . .
    principles" of Massachusetts products liability law:    first,
    that "[a] plaintiff who sues a particular manufacturer for
    product liability generally must be able to prove that the
    [product] which it is claimed caused the injury can be traced to
    that specific manufacturer," Mathers v. Midland-Ross Corp., 
    403 Mass. 688
    , 691 (1989); and second, that a manufacturer cannot be
    held liable "for failure to warn of risks created solely in the
    use or misuse of the product of another manufacturer" (emphasis
    added).   
    Mitchell, 396 Mass. at 631
    .   Because Merck did not
    manufacture the finasteride that allegedly caused Rafferty's
    injury, the judge concluded that Merck could not be held liable
    for his injuries.   The judge, quoting the Iowa Supreme Court
    opinion in Huck v. Wyeth, Inc., 
    850 N.W.2d 353
    , 376-377 (Iowa
    2014), cert. denied, 
    135 S. Ct. 1699
    (2015), declared that
    imposing liability on Merck for an injury caused by a
    competitor's product would not only disturb the balance struck
    between brand-name and generic manufacturers in the Hatch-Waxman
    amendments -- which courts are not "institutionally qualified"
    11
    to second-guess -- but also run contrary to the fundamental
    principle of tort law that "[l]iability generally follows
    control."    
    Id. at 378.
      Similarly, with respect to Rafferty's
    c. 93A claim, the judge concluded that there could be no
    violation of the consumer protection statute where there was no
    duty of care owed to the consumer.
    After the judge dismissed both claims, a final judgment
    entered in favor of Merck.    Rafferty now appeals from that final
    judgment and from the judge's decision allowing Merck's motion
    to dismiss.    We transferred this case from the Appeals Court on
    our own motion.
    Discussion.    We review a judge's decision to dismiss a
    claim de novo, accepting as true the allegations in the
    complaint and drawing every reasonable inference in favor of the
    plaintiff.    See Curtis v. Herb Chambers I-95, Inc., 
    458 Mass. 674
    , 676 (2011).    Our task is to "consider whether the factual
    allegations in the complaint are sufficient, as a matter of law,
    to state a recognized cause of action or claim, and whether such
    allegations plausibly suggest an entitlement to relief."
    Dartmouth v. Greater New Bedford Regional Vocational Tech. High
    Sch. Dist., 
    461 Mass. 366
    , 374 (2012).    Here, Rafferty has
    asserted two claims, the first for negligence based on failure
    to warn, and the second for a violation of c. 93A.    We address
    each of these claims in turn.
    12
    1.   Negligence claim.   "To recover for negligence, a
    plaintiff must show 'the existence of an act or omission in
    violation of a . . . duty owed to the plaintiff[] by the
    defendant.'"    Cottam v. CVS Pharmacy, 
    436 Mass. 316
    , 320 (2002),
    quoting Dinsky v. Framingham, 
    386 Mass. 801
    , 804 (1982).        The
    existence of a duty is a question of law for the courts.
    Cottam, supra at 321.     Here, the question is whether Merck, as
    the brand-name manufacturer of finasteride, owed a duty to warn
    to those, like Rafferty, who ingested the generic version of the
    drug.
    Typically, where a consumer is injured by a product, our
    law holds the manufacturer or seller responsible under a theory
    of products liability.    See, e.g., H.P. Hood & Sons, Inc. v.
    Ford Motor Co., 
    370 Mass. 69
    , 75 (1976).     But Rafferty concedes,
    as he must under our prevailing law, that Merck owes him no duty
    to warn under the law of products liability.      As noted by the
    judge, a manufacturer may be found liable for a failure to warn
    only where the product that caused the injury was made by that
    manufacturer; its duty of care extends only to users of its own
    product.     See 
    Mathers, 403 Mass. at 691
    ; 
    Mitchell, 396 Mass. at 631
    .    This principle was applied in Carrier v. Riddell, Inc.,
    
    721 F.2d 867
    , 868 (1st Cir. 1983), where the plaintiff, a high
    school football player, suffered a severe spinal injury playing
    football and sued the defendant, a helmet manufacturer, claiming
    13
    that it negligently failed to warn his team that helmets offer
    little protection to a player's neck and spine.     When the
    plaintiff learned in discovery that the helmet he wore was made
    by another manufacturer, not the defendant, the plaintiff
    continued to press his claim, arguing that his teammates wore
    helmets made by the defendant manufacturer and that, if it had
    provided a general warning about a helmet's limitations, he
    would have heard that warning and taken additional precautions
    that would have prevented his injury.     
    Id. In an
    opinion
    written by now United States Supreme Court Justice Stephen
    Breyer, the United States Court of Appeals for the First
    Circuit, applying Massachusetts law, held that the defendant
    manufacturer could not be liable for failing to warn the
    plaintiff.   
    Id. at 870.
      The court reasoned, "In the absence of
    some special circumstance one would expect a purchaser or a user
    of a product to rely for warnings upon the maker of the product
    they buy or use, not upon the maker of another, similar
    product."    
    Id. at 869.
      As a general principle of products
    liability law, the court concluded that a manufacturer's "duty
    of care runs to those who buy or use the product itself, not a
    different [manufacturer's] product."     
    Id. Here, however,
    Rafferty did not bring a products liability
    claim and does not contend that Merck owed him a duty to warn as
    a manufacturer.   Instead, he has brought a general negligence
    14
    claim, relying on "a general principle of tort law" that we
    articulated in Jupin v. Kask, 
    447 Mass. 141
    , 147 (2006), quoting
    Remy v. MacDonald, 
    440 Mass. 675
    , 677 (2004).   In 
    Jupin, supra
    ,
    we declared:
    "'[E]very actor has a duty to exercise reasonable care to
    avoid physical harm to others.' . . . A precondition to
    this duty is, of course, that the risk of harm to another
    be recognizable or foreseeable to the actor. . . .
    Consequently, with some important exceptions, 'a defendant
    owes a duty of care to all persons who are foreseeably
    endangered by his conduct, with respect to all risks which
    make the conduct unreasonably dangerous.'" (Citations
    omitted.)
    Applying this "general principle," 
    id., we held
    in Jupin
    that a homeowner who stores firearms on his or her property has
    a duty of reasonable care to ensure that those firearms are
    properly secured, and that that duty was owed to, among others,
    a law enforcement officer shot by a person granted unsupervised
    access, because he was a "foreseeable victim" of the improper
    storage.   
    Id. at 143.
      Under that same principle, we also have
    held, for example, that a limousine driver who discharges an
    intoxicated passenger, knowing that that passenger is likely to
    drive while intoxicated, owes a duty of reasonable care to those
    who are foreseeably endangered by the passenger's drunk driving.
    Commerce Ins. Co. v. Ultimate Livery Serv., Inc., 
    452 Mass. 639
    ,
    649-651 (2008).   Similarly, we have held that an attorney owes a
    duty of reasonable care to nonclients, absent a conflict with a
    15
    client's interest, if he or she knows or should know that the
    nonclient will rely on the attorney's advice, see Lamare v.
    Basbanes, 
    418 Mass. 274
    , 276 (1994), and that an accountant owes
    a duty of reasonable care to third parties if the accountant
    knows that they will rely on the audit he or she prepares.
    Nycal Corp. v. KPMG Peat Marwick, LLP, 
    426 Mass. 491
    , 495-498
    (1998).
    At the same time, we recognized in Jupin that, even where
    the requirements of negligence are satisfied, there may
    nevertheless be a public policy justification for declining to
    impose a duty of care where "the imposition of a precautionary
    duty is deemed to be either inadvisable or unworkable."     
    Jupin, 447 Mass. at 150-151
    , quoting 
    Remy, 440 Mass. at 677
    .     "The
    concept of 'duty' . . . 'is not sacrosanct in itself, but is
    only an expression of the sum total of . . . considerations of
    policy which lead the law to say that the plaintiff is entitled
    to protection.'"    Luoni v. Berube, 
    431 Mass. 729
    , 735 (2000),
    quoting W.L. Prosser & W.P. Keeton, Torts § 53, at 358 (5th ed.
    1984).    Thus, the existence of duty is ultimately determined
    with "reference to existing social values and customs and
    appropriate social policy."    Cremins v. Clancy, 
    415 Mass. 289
    ,
    292 (1993).   This approach comports with the one taken by the
    Restatement (Third) of Torts, which provides:
    16
    "(a) An actor ordinarily has a duty to exercise reasonable
    care when the actor's conduct creates a risk of physical
    harm.
    "(b) In exceptional cases, when an articulated
    countervailing principle or policy warrants denying or
    limiting liability in a particular class of cases, a court
    may decide that the defendant has no duty or that the
    ordinary duty of reasonable care requires modification."
    Restatement (Third) of Torts:   Liability for Physical and
    Emotional Harm § 7 (2010).
    Merck contends that, where a plaintiff alleges injury
    caused by a product arising from a failure to warn, we should
    limit the duty to warn to the manufacturer of that particular
    product, regardless of whether the claim is framed as a products
    liability claim or, as here, as a general negligence claim.     It
    is true that, in the vast majority of such cases, the duty to
    warn would be limited to the manufacturer of the product -- even
    if the plaintiff were to bring a general negligence claim --
    because the risk of harm arising from an inadequate warning
    would be foreseeable to a manufacturer only with respect to
    users of its own product, not the users of another product.
    Where the product causing the injury carries its own warning,
    one would expect the plaintiff to rely on that warning, not on
    the warning given for another product.   Moreover, apart from any
    duty arising from the risk of foreseeable injury, only in rare
    17
    cases could a plaintiff contend that his or her injury was
    caused by the inadequate warning given for another product.
    But this case presents an exception to the usual pattern.
    Because the Hatch-Waxman amendments to the act require that the
    warning label of a generic drug be identical to the warning
    label of its brand-name counterpart, and because the United
    States Supreme Court in 
    PLIVA, 564 U.S. at 614-615
    , interpreted
    the resulting regulatory scheme to forbid a generic drug
    manufacturer from independently revising its warning labels,
    duty to warn claims involving generic drugs are potentially
    viable as general negligence claims, although not as products
    liability claims.   With generic drugs, it is not merely
    foreseeable but certain that the warning label provided by the
    brand-name manufacturer will be identical to the warning label
    provided by the generic manufacturer, and moreover that it will
    be relied on, not only by users of its own product, but also by
    users of the generic product.   Unlike in 
    Carrier, 721 F.2d at 869
    , where the defendant manufacturer exercised no control
    whatsoever over the warnings attached to another manufacturer's
    product, Federal labeling requirements for generic drugs present
    precisely the kind of "special circumstance" where a consumer
    would rely on the warnings created by someone other than the
    manufacturer of the product causing the injury, because those
    will be identical to (and inseparable from) the warnings
    18
    provided by the generic manufacturer.     Where a brand-name drug
    manufacturer provides an inadequate warning for its own product,
    it knows or should know that it puts at risk not only the users
    of its own product, but also the users of the generic product.
    Consequently, this is the rare (perhaps the only) type of case
    involving a manufactured product where the requirements of
    general negligence may be satisfied even where the requirements
    of products liability are not.
    However, as noted earlier, even where the requirements of
    general negligence are satisfied, we must still consider as a
    matter of public policy whether the imposition of a duty is
    "inadvisable or unworkable," see 
    Jupin, 447 Mass. at 151
    ,
    quoting 
    Remy, 440 Mass. at 677
    , or, in the words of the
    Restatement (Third) of 
    Torts, supra
    at § 7, whether this is an
    "exceptional case[]" where a "countervailing principle or policy
    warrants denying or limiting liability" in this class of cases.
    "Public policy favors the development and marketing of new
    and more efficacious drugs."     Payton v. Abbott Labs, 
    386 Mass. 540
    , 573 (1982).   Therefore, we must carefully consider whether
    the imposition of general negligence liability on brand-name
    manufacturers for injuries suffered by generic drug consumers
    arising from a failure to warn would materially diminish the
    development and marketing of new drugs.
    19
    Inevitably, imposing on brand-name manufacturers a duty to
    warn generic drug consumers would add to the manufacturer's
    costs.   Where there is a duty to warn, negligence may be found
    where there is a failure "to exercise reasonable care in warning
    potential users of hazards associated with use of the product."
    Laaperi v. Sears, Roebuck & Co., 
    787 F.2d 726
    , 729 (1st Cir.
    1986) (applying Massachusetts law).   "The common law duty to
    warn . . . necessitates a warning 'comprehensible to the average
    user and . . . convey[ing] a fair indication of the nature and
    extent of the danger to the mind of a reasonably prudent
    person.'"   MacDonald v. Ortho Pharm. Corp., 
    394 Mass. 131
    , 140,
    cert. denied., 
    474 U.S. 920
    (1985), quoting Ortho Pharm. Corp.
    v. Chapman, 
    180 Ind. App. 33
    , 49 (1979).   "Whether a particular
    warning measures up to this standard is almost always an issue
    to be resolved by a jury; few questions are 'more appropriately
    left to a common sense lay judgment than that of whether a
    written warning gets its message across to an average person.'"
    
    MacDonald, supra
    , quoting Ferebee v. Chevron Chem. Co., 552 F.
    Supp. 1293, 1304 (D.D.C. 1982).   The breadth and uncertain scope
    of this standard for a negligent failure to warn means that,
    where a consumer suffers injury from a generic drug, there would
    be broad latitude to bring a failure to warn claim and great
    difficulty in defeating it before trial.   As a result, brand-
    name manufacturers faced with failure to warn claims would bear
    20
    the significant cost not only of compensating injured consumers,
    but also of litigating their claims, meritorious or not.
    Where failure to warn claims are brought by consumers of a
    manufacturer's own product, "the risk of injury can be insured
    by the manufacturer and distributed among the public as a cost
    of doing business."   Escola v. Coca Cola Bottling Co. of Fresno,
    
    24 Cal. 2d 453
    , 462 (1944) (Traynor, J., concurring).     The cost
    of litigation and of damage awards or settlements is in this
    sense treated as "a cost of production."   Restatement (Second)
    of Torts § 402A comment c (1965).   But if consumers of generic
    drugs were allowed to recover damages for a brand-name
    manufacturer's negligent failure to warn, it would be far more
    difficult for the manufacturer to shoulder these costs, for
    three reasons.
    First, these costs would not be incurred until after the
    brand-name manufacturer's patent monopoly expires and generic
    competitors enter the market, at which point the brand-name
    manufacturer will have suffered a precipitous decline in sales
    of its product.   When there is such competition, generic
    manufacturers command approximately ninety per cent of the
    market, see Association for Accessible Medicines, Generic Drug
    Access & Savings in the U.S. 16 (2017), in part because many
    States, including Massachusetts, have enacted laws that
    authorize or even require pharmacists to substitute generic
    21
    drugs when filling prescriptions for brand-name drugs.   See,
    e.g., G. L. c. 112, § 12D (requiring generic substitution unless
    prescribing physician indicates "no substitution").   See also
    
    PLIVA, 564 U.S. at 628
    (Sotomayor, J., dissenting); Grabowski,
    Long, Mortimer, & Boyo, Updated Trends in US Brand-Name and
    Generic Drug Competition, 19 J. Med. Econ. 836, 840 (2016)
    (brand-name drugs facing generic competition between 2013 and
    2014 saw market share by volume fall to average of twelve per
    cent within first year).
    Second, because prices drop with generic drug competition,
    the sales of generic drugs may exceed the sales generated during
    the patent monopoly period, and may even continue indefinitely,
    long after the brand-name manufacturer has moved on to focus on
    other patented products.   See United States Department of Health
    and Human Services, Office of the Assistant Secretary for
    Planning and Evaluation, Issue Brief:   Understanding Recent
    Trends in Generic Drug Prices 1-2 (Jan. 27, 2016).
    Third, because the United States Supreme Court in 
    PLIVA, 564 U.S. at 624
    , ruled that Federal preemption bars any generic
    drug consumer from bringing a failure to warn claim against any
    generic manufacturer, all such claims would be brought only
    against the brand-name manufacturer that drafted the warning
    label, leaving the brand-name manufacturer without any ability
    22
    to share the costs of litigation, or of a damage award or
    settlement, with the generic manufacturer.
    Therefore, although brand-name manufacturers are in the
    best position, because of their Federal labeling
    responsibilities, to prevent an injury arising from the
    inaccurate or inadequate warning on a generic drug, they are not
    in the best position to bear its costs.   To recognize negligence
    liability here would impose on brand-name manufacturers an
    additional "cost of production" for products that, in reality,
    they no longer produce.   Restatement (Second) of 
    Torts, supra
    at
    § 402A comment c.
    These additional costs, and the uncertainty regarding their
    scope and duration, would inevitably affect to some degree the
    financial incentives to invest in the research and development
    of new drugs.   Having said that, it is difficult to accurately
    assess whether, and to what extent, this would have a chilling
    effect on drug innovation.   See S. Garber, RAND Institute for
    Civil Justice, Economic Effects of Product Liability and Other
    Litigation Involving the Safety and Effectiveness of
    Pharmaceuticals 55-56, 58, 62 (2013) (some evidence that
    expanded products liability has discouraged drug innovation, but
    "there is no reliable empirical basis for estimating in dollar
    terms the social costs or benefits of liability-induced . . .
    price increases, or effects on product safety, effectiveness, or
    23
    innovation").   We realize that bringing a new drug to market is
    already a long, expensive, and risky process; studies have shown
    that, on average, the process of developing and obtaining FDA
    approval for a new drug takes ten to fifteen years and costs
    $2.6 billion, and only a small fraction of compounds under
    development are ever approved.    See Pharmaceutical Research and
    Manufacturers of America, Biopharmaceuticals in Perspective 29
    (2017).   See also United States Department of Health and Human
    Services, Report to Congress, Prescription Drugs:    Innovation,
    Spending, and Patient Access 25-36 (Dec. 7, 2016).     Given that
    the costs of research and development are already so high and
    the odds of FDA approval so low, it is far from clear whether
    the development of any new drug would be prevented merely
    because of the incremental costs that would arise from the
    imposition of a duty to warn generic drug consumers.
    Meanwhile, imposing such a duty on brand-name manufacturers
    would have undeniable benefits.    We can be confident that, if
    brand-name manufacturers owed generic drug consumers a duty to
    warn, they would have a greater financial incentive to revise
    their warnings through the change being effected process where
    new information demonstrates the need to do so, in order to
    prevent failure to warn suits.    Without such a duty, the only
    threat of a failure to warn suit would be from consumers of the
    brand-name drug who, once the patent has expired and generic
    24
    drugs enter the market, might comprise as little as ten per cent
    or less of the market for such drugs.    As a result, no one --
    neither the generic manufacturer nor the brand-name manufacturer
    -- would have a complete incentive to maintain safe labels for
    the overwhelming share of prescription drugs dispensed.       State
    tort law always has been an important source of consumer
    protection with respect to prescription drugs, "provid[ing]
    incentives for drug manufacturers to disclose safety risks
    promptly."    Wyeth v. Levine, 
    555 U.S. 555
    , 579 (2009).   See
    Kessler & Vladeck, A Critical Examination of the FDA's Efforts
    to Preempt Failure-to-Warn Claims, 96 Geo. L.J. 461, 483, 491-
    495 (2008).    If generic drug consumers could not sue drug
    manufacturers for a failure to warn, they would be denied an
    important safeguard against future injuries.
    We also recognize that, if we were to shield brand-name
    manufacturers entirely from liability for the failure to warn
    generic drug consumers, we would leave those consumers with no
    chance of obtaining compensation for their injuries because
    generic manufacturers are already immune from State law claims.
    In 
    PLIVA, 564 U.S. at 625
    , the United States Supreme Court
    recognized "the unfortunate hand that [F]ederal drug regulation
    has dealt" generic drug consumers, whose claims against
    manufacturers are barred only because they ingested generic
    rather than brand-name drugs.    See 
    id. at 643
    (Sotomayor, J.,
    25
    dissenting) ("[Under PLIVA,] a drug consumer's right to
    compensation for inadequate warnings now turns on the
    happenstance of whether her pharmacist filled her prescription
    with a brand-name drug or a generic").   Were we also to bar
    their claims against brand-name manufacturers, we would only
    exacerbate the unfairness of this regulatory scheme.    Such a
    result would be especially troubling given that, as discussed,
    generic drugs represent close to ninety per cent of the
    prescription drug market, and many drug consumers do not even
    have a choice under State generic substitution laws whether they
    receive a brand-name or generic drug when they fill a
    prescription.   See 
    PLIVA, supra
    at 628 (Sotomayor, J.,
    dissenting).    The widespread use of generic drugs means that, if
    we decline to impose any liability on brand-name manufacturers,
    countless consumers would be left without a remedy.
    The need to deter failures to warn, and to compensate for
    the resulting harm, is especially urgent where the failure is
    not merely inadvertent and the risk of harm is most serious.     In
    other types of cases where we have circumscribed liability for
    public policy reasons, we have nevertheless consistently
    recognized that there is a certain core duty -- a certain
    irreducible minimum duty of care, owed to all persons -- that as
    a matter of public policy cannot be abrogated:   that is, the
    duty not to intentionally or recklessly cause harm to others.
    26
    For instance, we have long held in premises liability cases that
    a landowner owes no duty of reasonable care to a trespasser,
    Schofield v. Merrill, 
    386 Mass. 244
    , 245-246 (1982), based on
    the rationale that landowners should not be "bound to protect or
    provide safeguards for wrongdoers."    Sweeny v. Old Colony &
    Newport R.R. Co., 
    10 Allen 368
    , 372 (1865).     Yet, we have held
    that a landowner still owes a trespasser a duty to "refrain from
    wilful, wanton[,] or reckless disregard for the trespasser's
    safety."   Schofield, supra at 245-246.    And in cases involving
    contractual waivers, we have hewed to "the well-established
    principle of contract law" that "while a party may contract
    against liability for harm caused by its negligence, it may not
    do so with respect to its gross negligence" or, for that matter,
    its reckless or intentional conduct.      Maryland Cas. Co. v. NSTAR
    Elec. Co., 
    471 Mass. 416
    , 422 (2015), quoting Zavras v. Capeway
    Rovers Motorcycle Club, Inc., 
    44 Mass. App. Ct. 17
    , 19 (1997).
    See Sharon v. Newton, 
    437 Mass. 99
    , 110 n.12 (2002)
    (distinguishing waivers for ordinary negligence from waivers for
    "gross negligence, or reckless or intentional conduct");
    Restatement (Second) of Contracts § 195(1), at 65 (1981) ("A
    term exempting a party from tort liability for harm caused
    intentionally or recklessly is unenforceable on grounds of
    public policy").
    27
    We have applied this same reasoning in many other types of
    cases where we have tolerated ordinary negligence but drawn the
    line at recklessness.     In defamation cases, a plaintiff who is a
    public officer or a public figure cannot recover damages on
    proof of the defendant's negligence, but can recover if the
    defendant acted with "actual malice," meaning wilful or reckless
    disregard of the truth.    See Stone v. Essex County Newspapers,
    Inc., 
    367 Mass. 849
    , 851 (1975).    See also New York Times Co. v.
    Sullivan, 
    376 U.S. 254
    , 279-280 (1964).    In cases involving
    bailments, the traditional rule has been that where bailments
    are for the sole benefit of the bailor, the bailee is not liable
    for ordinary negligence but can be liable for gross negligence.
    See Altman v. Aronson, 
    231 Mass. 588
    , 590 (1919), quoting Foster
    v. Essex Bank, 
    17 Mass. 479
    , 498-499, 507 (1821).     Similarly, in
    cases involving sporting events, we have held that athletes and
    coaches cannot be liable for injuries caused by their
    negligence, but will be held liable if they act in "reckless
    disregard of safety."     Gauvin v. Clark, 
    404 Mass. 450
    , 454
    (1989).   See Kavanagh v. Trustees of Boston Univ., 
    440 Mass. 195
    , 204-205 (2003).
    In enacting statutes, the Legislature, too, has
    distinguished between ordinary negligence and reckless conduct,
    granting immunity or indemnification in some situations in
    claims of negligence but not in claims of recklessness.    See,
    28
    e.g., G. L. c. 21, § 17C (landowner who makes land open to
    public for recreational use free of charge not liable for
    personal injuries "in the absence of wilful, wanton, or reckless
    conduct"); G. L. c. 229, § 2 (railroads not liable for
    negligence in causing death of trespasser but liable for
    reckless conduct).   See also G. L. c. 258, § 9 (public employees
    may not be indemnified for civil rights violations if employee
    "acted in a grossly negligent, willful[,] or malicious manner);
    G. L. c. 258, § 9A (police officers may not be indemnified for
    violations of Federal or State law if officer "acted in a
    wilful, wanton, or malicious manner").
    Implicit in both our common and statutory law, then, is a
    longstanding public policy that, although we may be willing in
    certain circumstances to excuse ordinary negligence, we will not
    tolerate the reckless disregard of the safety of others.
    Having weighed these considerations, we conclude as a
    matter of public policy that allowing a generic drug consumer to
    bring a general negligence claim for failure to warn against a
    brand-name manufacturer poses too great a risk of chilling drug
    innovation, contrary to the public policy goals embodied in the
    Hatch-Waxman amendments.   But we also conclude that public
    policy is not served if generic drug consumers have no remedy
    for the failure of a brand-name manufacturer to warn in cases
    where such failure exceeds ordinary negligence, and rises to the
    29
    level of recklessness.   In cases where, for instance, a brand-
    name manufacturer learns that its drug is repeatedly causing
    death or serious injury, or causes birth defects when used by
    pregnant mothers, and still fails to warn consumers of this
    danger, public policy does not dictate that these consumers be
    left with no remedy when those risks are realized, or that the
    manufacturer have little financial incentive to reveal these
    risks.    We therefore hold that a brand-name manufacturer that
    controls the contents of the label on a generic drug owes a duty
    to consumers of that generic drug not to act in reckless
    disregard of an unreasonable risk of death or grave bodily
    injury.   This recklessness standard strikes the most appropriate
    balance between competing public policy interests, limiting
    liability for brand-name manufacturers while also providing
    remedies for the most serious injuries and deterring the most
    dangerous forms of conduct.
    Under our common law, a defendant's conduct is in reckless
    disregard of the safety of another where
    "he does an act or intentionally fails to do an act which
    it is his duty to the other to do, knowing or having reason
    to know of facts which would lead a reasonable man to
    realize, not only that his conduct creates an unreasonable
    risk of physical harm to another, but also that such risk
    is substantially greater than that which is necessary to
    make his conduct negligent."
    30
    Boyd v. National R.R. Passenger Corp., 
    446 Mass. 540
    , 546
    (2006), quoting Restatement (Second) of 
    Torts, supra
    at § 500,
    at 587.
    Recklessness is distinguishable from negligence in two key
    respects.   See Manning v. Nobile, 
    411 Mass. 382
    , 387-388 (1991).
    First, the reckless conduct must be intended.    "While negligence
    may result from 'inadvertence, incompetence, . . . or a failure
    to take [adequate] precautions,' recklessness 'requires a
    conscious choice of a course of action, either with knowledge of
    the serious danger to others involved in it or with knowledge of
    facts which would disclose this danger to any reasonable man.'"
    
    Boyd, 446 Mass. at 547
    , quoting Restatement (Second) of 
    Torts, supra
    at § 500 comment g, at 590.   Importantly, only the conduct
    need be intended; the resulting harm need not be.    Boyd, supra
    at 548.
    Second, reckless conduct must involve a substantially
    greater risk than is required for ordinary negligence.
    "Reckless failure to act involves an intentional or unreasonable
    disregard of a risk that presents a high degree of probability
    that substantial harm will result to another."    Sandler v.
    Commonwealth, 
    419 Mass. 334
    , 336 (1995).   "The risk of death or
    grave bodily injury must be known or reasonably apparent, and
    the harm must be a probable consequence of the defendant's
    election to run that risk or of his failure reasonably to
    31
    recognize it."   
    Id. The difference
    between recklessness and
    mere negligence is therefore not only "a difference in degree
    but also a difference in kind."    
    Id. at 337.
    Under this standard, a brand-name manufacturer that
    intentionally fails to update the label on its drug to warn of
    an unreasonable risk of death or grave bodily injury, where the
    manufacturer knows of this risk or knows of facts that would
    disclose this risk to any reasonable person, will be held
    responsible for the resulting harm.
    We acknowledge that, by imposing on brand-name
    manufacturers any duty to warn generic consumers, we find
    ourselves in the minority of courts that have decided this
    issue.   We also are the only court to limit the scope of
    liability arising under this duty to reckless disregard of the
    risk of death or grave bodily injury.   As Merck has repeatedly
    reminded us, most courts have held that brand-name manufacturers
    owe no duty to generic drug consumers who have been injured by
    inaccurate or inadequate labels.   See, e.g., Johnson v. Teva
    Pharms. USA, Inc., 
    758 F.3d 605
    , 616 (5th Cir. 2014); Guarino v.

    some because they were resolved under the products liability
    statutes of other States, see Johnson, supra at 615-616
    (applying Louisiana Products Liability Act); Smith, supra at
    423-424 (applying Kentucky Products Liability Act), and others
    because they were issued by Federal courts that are constrained
    in their interpretation of State law in the absence of clear
    guidance from State appellate courts.       See Guarino, supra at
    1251 ("[C]onsiderations of comity and federalism counsel that we
    proceed gingerly when venturing into uncharted waters of [S]tate
    substantive law").       Further, to the extent that several of these
    decisions predate the United States Supreme Court's decision in
    
    PLIVA, 564 U.S. at 613
    , 624, we find them less persuasive
    because they failed to consider the Federal preemption of State
    tort law claims against generic manufacturers and the unique
    remedial gap that this has created.6
    Only a few courts have held otherwise. See Wyeth, Inc. v.
    5
    Weeks, 
    159 So. 3d 649
    , 676 (Ala. 2014), superseded by statute,
    Ala. Code § 6-5-530(a); Conte v. Wyeth, Inc., 
    168 Cal. App. 4th 89
    , 114 (2008). See also Kellogg v. Wyeth, 
    762 F. Supp. 2d 694
    ,
    706 (D. Vt. 2010).
    For example, in Foster v. American Home Prods. Corp., 29
    
    6 F.3d 165
    , 169-171 (4th Cir. 1994), the United States Court of
    Appeals for the Fourth Circuit held that a brand-name
    manufacturer owed no duty to a generic drug consumer based in
    part on the premise that generic manufacturers have some control
    over the contents of their labels and can therefore be held
    33
    We also conclude that, by limiting liability to
    circumstances where there has been reckless disregard of an
    unreasonable risk of death or grave bodily injury, we adequately
    address the many policy concerns that have led other courts to
    deny liability altogether.    See, e.g., 
    Huck, 850 N.W.2d at 376
    -
    380.    First, our ruling does not undo the careful balance struck
    in the Hatch-Waxman amendments by imposing unwarranted new
    burdens on brand-name manufacturers.   We emphasize that,
    although we limit the brand-name manufacturer's duty to warn
    generic drug consumers, we do not limit its duty to warn its own
    customers; as to them, brand-name manufacturers still owe a duty
    to "exercise reasonable care in warning [them] of hazards
    associated with use of [their] product."    
    Laaperi, 787 F.2d at 729
    .    In addition to this common-law duty they already owe to
    their own customers, brand-name manufacturers also have a duty
    under the act to ensure that the labels on their products are
    accurate and adequate.   21 U.S.C. § 355(b)(1), (d).     FDA
    regulations impose on all drug manufacturers, both brand-name
    and generic, an ongoing obligation to monitor a drug's risks and
    report any adverse drug experiences that may not be indicated by
    the drug's label.    21 C.F.R. §§ 314.80, 314.81, 314.98.      Drug
    liable for negligent failure to warn. This premise is obviously
    no longer true in light of the United States Supreme Court's
    decision in PLIVA, Inc. v. Mensing, 
    564 U.S. 604
    , 613, 624
    (2011).
    34
    manufacturers also have a regulatory obligation to revise their
    labeling "to include a warning about a clinically significant
    hazard as soon as there is reasonable evidence."    21 C.F.R. §
    201.57(c)(6)(i) (2017).   See 21 C.F.R. § 201.80(e) (2017).    To
    avoid liability for recklessness toward generic drug consumers,
    a brand-name manufacturer need only fulfil those obligations it
    already has towards its own customers.   Cf. Coombes v. Florio,
    
    450 Mass. 182
    , 191 (2007) (Ireland, J., concurring) (extension
    of doctor's duty to warn to nonpatients "d[id] not impose a
    heavy burden" where it "require[d] nothing . . . not already
    required by his duty to his patient").
    Second, to the extent that our decision makes investments
    in new drugs any "riskier" -- by exposing manufacturers to
    additional liability -- we expect that this marginal risk will
    not materially chill innovation or increase drug prices.    After
    all, what drug manufacturer, when deciding whether to invest in
    a new drug or in setting prices during its patent monopoly,
    would factor in substantial liability costs that might be
    incurred after its patent expires, premised on the probability
    that it will act in reckless disregard of an unreasonable risk
    of death or grave bodily injury?
    Third, we do not believe that by recognizing liability for
    recklessness we overstep our bounds and intrude into matters for
    which "courts are not institutionally qualified."   Huck, 
    850 35 N.W.2d at 377
    .   In enacting the Hatch-Waxman amendments,
    Congress has determined that public health and safety is best
    served by a particular allocation of labeling responsibilities
    between brand-name and generic manufacturers.    We cannot (nor do
    we seek to) disturb that allocation.   Congress recognized and
    expected that its Federal regulatory scheme would be
    supplemented with traditional State law remedies.    When Congress
    enacted the act, it rejected an earlier draft that would have
    provided a Federal cause of action for injured consumers,
    "[e]vidently, [because] it determined that [State law] provided
    appropriate relief."   
    Wyeth, 555 U.S. at 574
    & n.7.
    Fourth, our decision does not subvert the fundamental
    principles of tort law.   On the contrary, it is fully consistent
    with them.   As earlier noted, the relief we provide, limited to
    reckless disregard of an unreasonable risk of death or grave
    bodily injury, is coextensive with the irreducible minimum duty
    of care that as a matter of public policy cannot be abrogated,
    even where a trespasser invades a person's property or when the
    parties contractually agree to a waiver of liability.
    In this case, the question whether Rafferty has stated a
    failure to warn claim that meets the standard of a reckless
    disregard of an unreasonable risk of death or grave bodily
    injury must be determined by a trial judge.     Because Merck owed
    Rafferty a limited duty to warn, and because Rafferty, to state
    36
    a claim that falls within this limited duty, must allege facts
    supporting a finding that Merck acted recklessly, not just
    negligently, we vacate the dismissal of this claim and remand
    the case to the Superior Court.   We direct the court to grant
    leave to Rafferty to amend his complaint if he believes that he
    can state facts sufficient to support such a claim.   Cf. Cheney
    v. Automatic Sprinkler Corp. of Am., 
    377 Mass. 141
    , 150 (1979)
    (plaintiff given opportunity to amend complaint where court "for
    the first time . . . [indicated] the relevant considerations"
    for his claim).
    2.   Chapter 93A claim.   To state a claim under the consumer
    protection statute, G. L. c. 93A, § 9, a plaintiff must allege
    facts sufficient to establish four elements:   first, that the
    defendant has committed an unfair or deceptive act or practice;
    second, that the unfair or deceptive act or practice occurred
    "in the conduct of any trade or commerce;" third, that the
    plaintiff suffered an injury; and fourth, that the defendant's
    unfair or deceptive conduct was a cause of the injury.
    See G. L. c. 93A, § 2 (a); Herman v. Admit One Ticket Agency
    LLC, 
    454 Mass. 611
    , 615-616 (2009).
    Under § 2, "unfair or deceptive acts or practices" are
    "declared unlawful" only where they occur "in the conduct of any
    trade or commerce."   "Trade" and "commerce" are defined in
    § 1 (b) to include "the advertising, the offering for sale,
    37
    . . . the sale, . . . or distribution of any services and any
    property, tangible or intangible, . . . and any other article,
    commodity, or thing of value wherever situate, and shall include
    any trade or commerce directly or indirectly affecting the
    people of this [C]ommonwealth."
    To satisfy the "trade or commerce" requirement in a failure
    to warn claim under G. L. c. 93A, § 9, a plaintiff need not have
    purchased the product directly from the defendant.   See Kattar
    v. Demoulas, 
    433 Mass. 1
    , 14-15 (2000) ("Parties need not be in
    privity for their actions to come within the reach of c. 93A").
    It suffices that the plaintiff used the product, even if it was
    sold to another, and was injured as a result of the defendant's
    failure to warn.   See Maillet v. ATF-Davidson, Co., 
    407 Mass. 185
    , 190 (1990) (injured printing press operator could sue
    manufacturer of printing press purchased by his employer, even
    though he was "neither a consumer nor in privity with the
    defendant").   See also Ciardi v. F. Hoffmann-La Roche, Ltd., 
    436 Mass. 53
    , 65 (2002) (indirect purchaser of product could assert
    c. 93A claim for unfair competition against manufacturer of that
    product, notwithstanding lack of privity, because she "alleged a
    connection between herself and the defendants, albeit an
    indirect one, as parties to consumer transactions").7
    7 It is important to distinguish between claims brought
    under G. L. c. 93A, § 9, typically by consumers against
    38
    Here, however, Rafferty does not allege that he used
    Merck's brand-name drug.   Rather, he alleges that he suffered
    injury from the use of a drug that Merck did not advertise,
    offer to sell, or sell.    Although c. 93A does not require
    privity, it is limited "only to actions taken in the course of
    'trade or commerce'" (emphasis added).    Morrison v. Toys "R" Us,
    Inc., Mass., 
    441 Mass. 451
    , 457 (2004).    In this context,
    Merck's alleged unfair and deceptive action -- that is, its
    failure to warn Rafferty of the side effects of the drug -- was
    not taken in the course of "any trade or commerce" because it
    was not taken in the course of the advertising, offer to sell,
    or sale of any Merck product.   Of course, if one of Merck's own
    consumers was injured from Merck's brand-name version of the
    drug as a result of its failure to warn, that failure would have
    been in the course of Merck's sale of its own product, and
    therefore "in the conduct of any trade or commerce."    G. L.
    c. 93A, § 2 (a).   But where the failure to warn is with respect
    to a drug that Merck has never advertised, offered to sell, or
    sold, it would stretch the limits of c. 93A to hold that such
    businesses, and claims brought under § 11, typically by
    businesses against other businesses. Unlike claims under § 9,
    claims under § 11 require not only that the defendant's conduct
    occur in "trade or commerce" but also that there be a commercial
    transaction between the parties. See Linkage Corp. v. Trustees
    of Boston Univ., 
    425 Mass. 1
    , 22-23, cert. denied, 
    522 U.S. 1015
    (1997).
    39
    failure occurred "in the conduct of any trade or commerce."   
    Id. We therefore
    conclude that Rafferty has failed to allege
    sufficient facts to state a claim under c. 93A, § 9.
    Conclusion.   For the reasons stated above, the order
    dismissing Rafferty's common-law claim is vacated and the case
    is remanded to the Superior Court, with instructions that
    Rafferty be granted leave to amend his complaint within thirty
    days of the date of the rescript.   The order dismissing
    Rafferty's c. 93A claim is affirmed.
    So ordered.
