Jamesway Corp., 660 F.Supp. 138, 141 (E.D.N.Y.1987)). Moreover, there is no special burden on a plaintiff alleging antitrust violations. See In re Nine West Shoes Antitrust Litig., 80 F.Supp.2d 181, 185 (S.D.N.Y.2000). “Our Circuit has stated that ‘a short plain statement of a claim for relief which gives notice to the opposing party is all that is necessary in antitrust cases, as in other cases under the Federal Rules.’ ” Id. (quoting George C. Frey Ready-Mixed Concrete, Inc. v. Pine Hill Concrete Mix Corp., 554 F.2d 551, 554 (2d Cir.1977)).
II. Section 1 of the Sherman Act
Section 1 of the Sherman Act provides, in pertinent part, that “[ejvery contract, combination in the form of trust or otherwise, or conspiracy, in restraint of trade or commerce among the several States, or with foreign nations, is hereby declared to be illegal.” 15 U.S.C. § 1. However, only unreasonable restraints are actionable under the antitrust laws. See State v. Saint Francis Hosp., 94 F.Supp.2d 399, 411 (S.D.N.Y.2000) (Conner, J.) (citing Northwest Wholesale Stationers, Inc. v. Pacific Stationery & Printing, Co., 472 U.S. 284, 289, 105 S.Ct. 2613, 86 L.Ed.2d 202 (1985)). To state a claim under Section 1 of the Sherman Act, a plaintiff must allege a combination or concerted action between at least two entities that unreasonably restrains interstate or foreign commerce. See Tops Mkts., Inc. v. Quality Mkts., Inc., 142 F.3d 90, 95-96 (2d Cir.1998). In this case, because plaintiffs allege that defendants met to discuss lower commissions and that commissions were thereafter actually lowered, plaintiffs have sufficiently alleged a conspiracy. See Ambook Enters. v. Time Inc., 612 F.2d 604, 614 (2d Cir.1979) (holding that an express agreement need not be alleged in order to prove a conspiracy). Moreover, plaintiffs clearly stated that defendants were distinct companies. (Am.Complt.¶¶ 9-10.)
The issue in this case is whether plaintiffs sufficiently alleged that the lowering of commissions constitutes an unreasonable restraint. A resolution of this isT sue involves a determination whether the alleged restraint is per se unlawful or whether it is governed by Rule of Reason analysis. See Saint Francis Hosp., 94 F.Supp.2d at 411. “ ‘The majority of allegedly anticompetitive conduct continues to be examined under the [R]ule of [R]eason.’ ” CDC Techs., Inc. v. IDEXX Labs., Inc., 186 F.3d 74, 80 (2d Cir.1999) (quoting Continental T.V., Inc. v. GTE Sylvania, Inc., 433 U.S. 36, 49-50, 97 S.Ct. 2549, 53 L.Ed.2d 568 (1977)).
Restraints are per se violative of the antitrust laws when they are “obviously anticompetitive.” Bogan v. Hodgkins, 166 F.3d 509, 514 (2d Cir.1999), aff'g in relevant part, Bogan v. Northwestern Mut. Life Ins., Co., 953 F.Supp. 532 (S.D.N.Y.1997) (Conner, J.). “[Cjertain agreements or practices which because of the pernicious effect on competition and lack of any redeeming virtue are conclusively presumed to be unreasonable and therefore illegal without any elaborate inquiry as to the precise harm they have caused or the business excuse for their use.” Id. (quoting Northern Pac. Ry. Co. v. United States, 356 U.S. 1, 5, 78 S.Ct. 514, 2 L.Ed.2d 545 (1958)). Because per se liability is imposed only when the Court can “predict with confidence that the [R]ule of [Rjeason will condemn it,” Arizona v. Maricopa County Med. Soc’y, 457 U.S. 332, 344, 102 S.Ct. 2466, 73 L.Ed.2d 48 (1982), “[cjourts have been reluctant to expand the categories of per se illegality.” Bogan, 166 F.3d at 514. These categories include both horizontal and vertical price fixing, group boycotts, division of markets and tying arrangements. See Northern Pac. Ry., 356 U.S. at 5, 78 S.Ct. 514; In re Nine West Shoes, 80 F.Supp.2d at 188
