OPINION AND ORDER

HENRY PITMAN, United States Magistrate Judge.
I. Introduction
By notice of motion dated July 10, 2013 (Docket Item 230), defendants Citigroup Global Markets, Inc. and The Yield Book, Inc. (collectively, “Defendants”) move for an Order pursuant to Rules 16, 26, and 37 of the Federal Rules of Civil Procedure (1) striking the Fourth Declaration of Dr. Jianqing Fan *33(“Fourth Fan Decl.”), which plaintiff filed in connection with its opposition to both Defendants’ motion for summary judgment and Defendants’ motion, made pursuant to Fed. R.Evid. 702 and Daubert v. Merrell Dow Pharm., 509 U.S. 579, 113 S.Ct. 2786, 125 L.Ed.2d 469 (1993), to exclude Dr. Fan’s 2007 Report and testimony concerning the opinions set forth in that report, and (2) awarding Defendants their expenses, including attorney’s fees and costs, incurred in connection with the present motion. Plaintiff Advanced Analytics, Inc. (“AAI”) opposes the motion on multiple grounds; however, in the event that the Fourth Fan Decl. is stricken, AAI requests, in the alternative, that it be granted leave to amend its opposition papers.
For the reasons set forth below, I (1) grant in part and deny in part Defendants’ motion to strike the Fourth Fan Deck; (2) grant in part and deny in part Defendants’ application for an Order directing AAI to reimburse Defendants for the costs and fees incurred in making this motion and (3) grant AAI’s request for leave to amend its papers in opposition to Defendants’ motion for summary judgment.
II. Facts
Given the lengthy history of this action, I assume the reader’s familiarity with the facts and background of this ease and reference only those facts that are necessary to explain this opinion.1
This action has been pending for over nine years, and arises from AAI’s allegations that Defendants misappropriated sequences of numbers developed by Plaintiffs principal, Xiaolu Wang, and either incorporated them into Defendants’ software product called the Yield Book, which offers models to price mortgage-backed securities, or used them to create new sequences of numbers for use in the Yield Book. The parties have conducted extensive fact and expert discovery over the years.
During a hearing held on January 17,2012, and after conferring with counsel, I set a revised discovery schedule and instructed the parties to raise discovery issues promptly, in order to ensure compliance with the schedule (Tr. of Discovery Conference, held on January 17, 2012 (Docket Item 146), at 78). In an Order issued immediately after the conference, I set the following schedule: (1) no later than May 17, 2012, AAI was to submit all expert disclosures; (2) no later than June 18, 2012, Defendants were to submit all expert disclosures and (3) all discovery, including expert discovery, was to be completed by July 17, 2012 (Order, dated January 19, 2012 (“Scheduling Order”) (Docket Item 143)).
Notwithstanding the Scheduling Order and my admonition that the parties raise discovery disputes promptly, AAI attempted to submit a reply expert report from Dr. Jianq-ing Fan after the May 17, 2012 deadline (“Fan Reply”) and requested yet additional discovery after the close of the discovery period (Tr. of Discovery Conference, held on July 18, 2012 (Docket Item 226)). Defendants moved to strike the Fan Reply on the grounds that it was untimely and did not constitute a proper “reply,” because it contained new information and opinions that were not within the scope of either parties’ prior expert disclosures (Tr. of Discovery Conference, held on September 5, 2012 (Docket Item 175), at 4). AAI argued that the Fan Reply was proper, notwithstanding its untimeliness, because Defendants had engaged in fraudulent conduct during the course of discovery by fabricating and tampering with evidence (Tr. of Discovery Conference, held on September 5, 2012 (Docket Item 175), at 7-10). After considering the parties’ written submissions and hearing oral argument, I found that there was “very, very little evidence, if any evidence” that Defendants had committed fraud and no justification for AAI’s belated filing of the Fan Reply (Tr. of Discovery Conference, held on September 5, 2012 (Docket Item 175), at 94). Accordingly, I granted Defendants’ motion to *34strike the Fan Reply, and granted in part and denied in part AAI’s application for additional discovery. Advanced Analytics, Inc. v. Citigroup Global Mkts., Inc., 04 Civ. 3531(LTS)(HBP), 2012 WL 7037319 at *1 (S.D.N.Y. Sept. 25, 2012).
AAI filed objections to my ruling striking the Fan Reply (Docket Items 195-97). On February 8, 2013, the Honorable Laura T. Swain, United States District Judge, overruled AAI’s objections in their entirety. Specifically, with regard to my decision to strike the Fan Reply, Judge Swain held:
Dr. Fan’s Reply Report was filed two weeks after the close of discovery. “If an expert’s report ‘does not rely [on] any information that was previously unknown or unavailable to him,’ it is not an appropriate supplemental report under Rule 26.” Cedar Petrochemicals, Inc. v. Dongbu Hannong Chemical Co., Ltd., 769 F.Supp.2d 269, 278 (S.D.N.Y.2011) [ (Francis, M.J.) ]. Plaintiff has not met its burden of establishing that Judge Pitman’s ruling granting Defendants’ motion to strike Dr. Fan’s Reply Report, memorialized in Judge Pitman’s September 25, 2012, Or-dei’, was either clearly erroneous or contrary to law. For these reasons and for substantially the reasons stated on the record by Judge Pitman, at the September 5, 2012, hearing, Plaintiffs objection is overruled.
Advanced Analytics, Inc. v. Citigroup Global Mkts., Inc., 04 Civ. 3531(LTS)(HBP), 2013 WL 489061 at *2 (S.D.N.Y. Feb. 8, 2013).
Subsequently, the parties stipulated to a briefing schedule for Defendants’ motion for summary judgment and their Rule 702/Dau-bert motion to exclude Dr. Fan’s initial report and testimony based on that report (Stipulation and Order on Briefing Schedule for Summary Judgment, dated February 22, 2013 (Docket Items 215, 216); Stipulation and Order on Briefing Schedule for Motion to Exclude, dated April 16, 2013 (Docket Item 218)). Defendants served these motions on April 5, 2013. AAI served its opposition to both motions on June 6, 2013; its opposition to both motions included the Fourth Fan Deck The Fourth Fan Deck is 91 pages long and is accompanied by 117 exhibits, at least three of which appear to be newly created documents that were never previously produced (see Exhibits WW, CCC and SSS). Although it is difficult to summarize briefly, the Fourth Fan Deck alleges that Defendants committed fraud during discovery and offers new theories and opinions in support of AAI’s claim that Defendants misappropriated its trade secrets. In addition, the Fourth Fan Deck incorporates in its entirety by reference the previously stricken Fan Reply and relies upon it (Fourth Fan Deck ¶¶ 19-26, 52, 63,100).
By letter, dated June 10, 2013, Defendants requested a conference in connection with their anticipated motion to strike the Fourth Fan Deck on the grounds that it was untimely and contained entirely new bases for AAI’s claims (Letter from Defendants to the undersigned, dated June 10, 2013). AAI also submitted a letter, dated June 17, 2013, requesting a conference in connection with an anticipated motion for sanctions against defendants that would be based on the allegations of discovery misconduct set forth in the Fourth Fan Deck (Letter from AAI to the Honorable Laura Taylor Swain, United States District Judge, and the undersigned, dated June 17, 2013).
By Order, dated June 19, 2013, I directed the parties to complete their briefing on Defendants’ motion to strike the Fourth Fan Deck and adjourned sine die the dates on which the remaining submissions in connection with Defendants’ pending motions would be due and deferred consideration of AAI’s contemplated motion for sanctions until the dispute concerning the Fourth Fan Deck was resolved (Order, dated June 19, 2013 (Docket Item 221)). AAI sought reconsideration of my June 19 Order (Docket Items 223, 224, 228). I denied that motion on July 11, 2013 (Endorsement, dated July 11, 2013 (Docket Item 229)).
III. Analysis
Defendants argue that the untimely submission of the Fourth Fan Deck violates the Scheduling Order and the expert disclosure requirements of Rule 26 of the Federal Rules of Civil Procedure, warranting preclusion and an award of attorney’s fees and costs, pursu*35ant to Fed.R.Civ.P. 16 and 37. AAI argues that the Fourth Fan Decl. is not subject to Rule 26’s disclosure requirement to the extent that AAI relies on it for purposes other than the merits of its claims and that, even if Rule 26 were applicable, AAI’s failure to comply with Rule 26 was substantially justified and harmless and that preclusion is, therefore, unwarranted. In addition, AAI contends that the Fourth Fan Decl. should not be stricken because it is properly within the scope of Fan’s initial expert report. Finally, AAI argues that an award of attorney’s fees is inappropriate because it did not act in bad faith.
A. Legal Standards
“The Court has power under Rule 16 of the Federal Rules of Civil Procedure, as well as power derived from its inherent authority to manage proceedings before it ... to impose sanctions in respect of conduct violative of scheduling orders and wasteful of the time of the Court and opposing counsel.” Dallas v. Goldberg, 95 Civ. 9076(LTS)(RLE), 2003 WL 22872325 at *1 (S.D.N.Y. Dec. 5, 2003) (Swain, D.J.), citing Chambers v. NASCO, 501 U.S. 32, 43-50, 111 S.Ct. 2123, 115 L.Ed.2d 27 (1991) and Roadway Express, Inc. v. Piper, 447 U.S. 752, 766, 100 S.Ct. 2455, 65 L.Ed.2d 488 (1980). The same is true under Rule 37: “[wjhether exercising its inherent power, or acting pursuant to Rule 37, a district court has wide discretion in sanctioning a party for discovery abuses.” Reilly v. Natwest Mkts. Grp. Inc., 181 F.3d 253, 267 (2d Cir.1999); see Design Strategy, Inc. v. Davis, 469 F.3d 284, 294 (2d Cir.2006).
1. Noncompliance with Court Orders
Among other things, Rule 16 governs scheduling matters and the district court’s general powers to manage its own proceedings. Rule 16(f)(1) provides that, “[o]n motion or on its own, the court may issue any just orders, including those authorized by Rule 37(b)(2)(A)(ii)-(vii), if a party ... fails to obey a scheduling or other pretrial order.” Rule 16(f)(1)(C). Rule 37(b)(2)(A)(ii)-(vii), which Rule 16(f) references, sets forth a nonexclusive list of sanctions a court may impose against a party for failing to comply with a court order. These include the sanctions of preclusion, dismissal, rendering of a default judgment or contempt. Accordingly, pursuant to Rule 16, a party’s failure to comply with a scheduling or pretrial order may result in preclusion. See RLI Ins. Co. v. May Const. Co., Inc., 09 Civ. 7415(PKC), 2011 WL 1197937 at *2 n. 1 (S.D.N.Y. Mar. 22, 2011) (Castel, D.J.) (granting motion to strike for party’s failure to obey scheduling order under Rule 16(f)); Farricker v. Penson Dev., Inc., 07 Civ. 11191(PKC), 2010 WL 4456850 at *2 n. 2 (S.D.N.Y. Oct. 28, 2010) (Castel, D.J.) (same).
2. Rule 26(a)(2)(B)’s Disclosure Requirements
Fed.R.Civ.P. 26(a)(2) governs expert disclosures. Rule 26(a)(2)(B) requires an expert witness to provide a written report “if the [expert] witness is one retained or specially employed to provide expert testimony in the case or one whose duties as the party’s employee regularly involve giving expert testimony.” The written report must include, inter alia, “a complete statement of all opinions the witness will express and the basis and reasons for them; the facts or data considered by the witness in forming them; [and] any exhibits that will be used to summarize or support them.” Rule 26(a)(2)(B)(i)-(iii) (emphasis added). As explained in the Advisory Committee notes, Rule 26(a) “requires that persons retained or specially employed to provide expert testimony ... must prepare a detailed and complete written report, stating the testimony the witness is expected to present during direct examination, together with the reasons therefor.” Rule 26(a)(2)(B) Advisory Committee Notes on 1993 amend. ¶ (2)(B) (emphasis added). “The purpose of the rule is to prevent the practice of ‘sandbagging’ an opposing party with new evidence.” Ebewo v. Martinez, 309 F.Supp.2d 600, 607 (S.D.N.Y. 2004) (Koeltl, D.J.) (citations omitted). To that same end, Rule 26 also imposes a continuing obligation on parties to supplement or correct expert disclosures “in a timely manner.” Rule 26(e)(1)(A).
Pursuant to Rule 37(e)(1), a party who fails to provide information required un*36der Rule 26(a) or (e), “is not allowed to use that information ... to supply evidence on a motion, at a hearing, or at a trial, unless the failure was substantially justified or is harmless” (emphasis added). Like Rule 16(f), Rule 37(e)(1)(C) permits the court to impose any other sanction it deems appropriate, including those listed in Rule 37(b)(2)(A)(i)-(vi). Although there is language in the Advisory Committee Notes to the 1993 amendments to Rule 37 suggesting that preclusion is intended as an “automatic sanction” for untimely disclosures, the Court of Appeals for the Second Circuit has explained that the structure of the Rule does not warrant this interpretation and has directed District Courts to use a more flexible approach in assessing the consequences of a party’s untimely disclosure or amendment of a disclosure previously made. Design Strategy Inc. v. Davis, supra, 469 F.3d at 296-98. Specifically, the Court of Appeals has identified four factors to be considered in determining whether an order of preclusion is appropriate:
(1) the party’s explanation for the failure to comply with the [disclosure requirement]; (2) the importance of the testimony of the precluded witnesses]; (3) the prejudice suffered by the opposing party as a result of having to prepare to meet the new testimony; and (4) the possibility of a continuance.
Patterson v. Balsamico, 440 F.3d 104, 117 (2d Cir.2006) (alterations in original), citing Softel, Inc. v. Dragon Med. & Scientific Commc’ns, Inc., 118 F.3d 955, 961 (2d Cir. 1997). A finding of bad faith, however, is not required before sanctions can be imposed under Fed.R.Civ.P. 37(c)(1). Design Strategy, Inc. v. Davis, 469 F.3d at 296.
“[T]o the extent that an expert affidavit is within the scope of the initial expert report, it is properly submitted in conjunction with dispositive motions even outside the time frame for expert discovery.” Cedar Petrochemicals, Inc. v. Dongbu Hannong Chem. Co., 769 F.Supp.2d 269, 279 (S.D.N.Y. 2011) (Francis, M.J.) (citations omitted); accord Commercial Data Servers, Inc. v. Int’l Bus. Machs. Corp., 262 F.Supp.2d 50, 61 (S.D.N.Y.2003) (McMahon, D.J.) (considering untimely expert affidavit on motion for summary judgment because it was “substantially similar” to expert’s Rule 26 report). However,
“[ e]xpert testimony exceeding the bounds of the expert’s report is excludable pursuant to Rule 37(c)(1).” In re Kreta Shipping, S.A., 181 F.R.D. 273, 275 (S.D.N.Y.1998) [ (Wood, D.J.) ]; see also Rowe Entm’t, Inc. v. William Morris Agency, Inc., 98-CV-8272 (RPP), 2003 U.S. Dist. LEXIS 17623, at *5 n. 3, 2003 WL 22272587 [at *1 n. 3] (S.D.N.Y. Oct. 2, 2003) [ (Patterson, D.J.) ] (confining testimony from expert to opinions set forth in his expert report). The “duty to disclose information concerning expert testimony is intended to allow opposing parties to have a reasonable opportunity [to] prepare for effective cross examination and, perhaps, arrange for expert testimony from other witnesses.” LaMarca v. United States, 31 F.Supp.2d 110, 122 (E.D.N.Y.1999) (citation and internal quotation marks omitted). Thus, “courts will not admit supplemental expert evidence following the close of discovery when it ‘expoundfs] a wholly new and complex approach designed to fill a significant and logical gap in the first report,’ as doing so “would eviscerate the purpose of the expert disclosure rules.’ ” Cedar Petrochemicals, Inc. v. Dongbu Hannong Chem. Co., 769 F.Supp.2d 269, 279 (S.D.N.Y.2011) [ (Francis, M.J.) ] (quoting United States v. City of N.Y., 637 F.Supp.2d 77, 107 (E.D.N.Y.2009)); see also Silivanch v. Celebrity Cruises, Inc., 171 F.Supp.2d 241, 256 (S.D.N.Y.2001) [ (Francis, M.J.) ] (precluding expert testimony that was not disclosed during expert discovery).
Morritt v. Stryker Corp., 07-CV-2319 (RRM)(RER), 2011 WL 3876960 at *5 (E.D.N.Y. Sept. 1, 2011).
3. Attorney’s Fees and Costs
Pursuant to Rule 16(f)(2), Rule 37(c)(1) and the court’s inherent power to manage court proceedings, both a party and its counsel may be held liable for the expenses, including attorney’s fees and costs, resulting from the violation of either a scheduling order or Rule 26(a). Rule 16(f)(2) mandates the award of attorney’s fees for an unjustified violation of *37a scheduling or pretrial order: “[i]nstead of or in addition to any other sanction, the court must order the [violating] party, its attorney, or both to pay the reasonable expenses— including attorney’s fees — incurred because of any noncompliance with this rule, unless the noncompliance was substantially justified or other circumstances make an award of expenses unjust.” Fed.R.Civ.P. 16(f)(2) (emphasis added). Pursuant to Rule 37(c)(1)(A), a court has discretion to “order payment of the reasonable expenses, including attorney’s fees, caused by the failure” to disclose or supplement an expert report. In addition, the court has the inherent power to assess attorney’s fees against either the party or counsel for misconduct or the willful disobedience of a court order. See Chambers v. NASCO, 501 U.S. 32, 45, 111 S.Ct. 2123, 115 L.Ed.2d 27 (1991); United States v. Int’l Brotherhood of Teamsters, Chauffeurs, Warehousemen & Helpers of Am., AFL-CIO, 948 F.2d 1338, 1345 (2d Cir.1991), citing Alyeska Pipeline Serv. Co. v. Wilderness Soc’y, 421 U.S. 240, 258-59, 95 S.Ct. 1612, 44 L.Ed.2d 141 (1975).
The decision to impose sanctions “is committed to the sound discretion of the district court and may not be reversed absent an abuse of discretion.” Luft v. Crown Publishers, Inc., 906 F.2d 862, 865 (2d Cir.1990), citing, inter alia, Nat’l Hockey League v. Metro. Hockey Club, Inc., 427 U.S. 639, 642, 96 S.Ct. 2778, 49 L.Ed.2d 747 (1976) (per curiam); see Design Strategy, Inc. v. Davis, supra, 469 F.3d 284 at 294 (“A district court has wide discretion in imposing sanctions, including severe sanctions, under [Rule] 37____”); Daval Steel Prods. v. M/V Fakredine, 951 F.2d 1357, 1365 (2d Cir.1991) (same); Dove v. City of New York, 06 Civ. 1096(SAS), 2006 WL 3802267 at *2 (S.D.N.Y. Dec. 26, 2006) (Scheindlin, D.J.) (same); see generally S. New England Tel. Co. v. Global NAPs Inc., 624 F.3d 123, 144-45 (2d Cir.2010).
B. Application of the Foregoing Principles
AAI seeks to use the Fourth Fan Deck for three different purposes: (1) in opposition to Defendants’ motion for summary judgment; (2) in opposition to Defendants’ Rule 702/Daubert motion to strike Dr. Fan’s 2007 report and related testimony and (3) in support of AAI’s own contemplated motion for sanctions. The first proposed use is directed to the merits of AAI’s claims while the latter two are not. Because I conclude that the rules that apply to AAI’s attempt to use the Fourth Fan Deck on the merits are different than the rules that apply to its attempt to use it for non-merits purposes, I shall analyze the two classes of uses separately.
1. Use of the Fourth Fan Decl. to Oppose Defendants’ Summary Judgment Motion
To the extent AAI seeks to use the Fourth Fan Deck to oppose Defendants’ motion for summary judgment, I conclude that it should be precluded because, as explained below, it is untimely under my scheduling Order and was served in violation of Rule 26(a)(2).
a. Violation of Two Court Orders as Basis for Preclusion
The Fourth Fan Deck expressly relies on and incorporates by reference the Fan Reply in its entirety (Fourth Fan Deck ¶¶ 19-26, 52, 63, 100), in disregard of both my Order that the Fan Reply be stricken, supra, 2012 WL 7037319 at *1, and Judge Swain’s Order, affirming that ruling, supra, 2013 WL 489061 at *2. AAI’s attempt to resuscitate the Fan Reply is particularly odd because AAI does not even bother to address the fact that both Judge Swain and myself have ruled that the Fan Reply should be stricken. AAI’s papers are completely silent on this issue, suggesting that AAI itself l’ealizes that it has no colorable argument to support its actions.
There can also be no dispute that AAI violated the Scheduling Order when it filed the Fourth Fan Deck as part of its opposition to Defendants’ motion for summary judgment on June 6, 2013. The Scheduling Order imposed a deadline of May 17, 2012 for the completion of AAI’s expert disclosures and a deadline of July 17, 2012 for the completion of all discovery (Docket Item 143). Despite these deadlines, AAI filed the Fourth Fan Deck more than a year after the deadline for its expert disclosures.
*38AAI argues that the untimely submission of the Fourth Fan Decl. is excusable for several reasons. First, it claims that the Fourth Fan Decl. relies on information produced only at the conclusion of fact discovery and that it was, therefore, impossible for Dr. Fan to produce the declaration any earlier (Plaintiffs Memorandum of Law in Opposition to Defendants’ Motion to Strike the Fourth Declaration of Jianqing Fan (“AAI Mem.”) (Docket Item 231) at 9,12). For the most part, AAI fails to cite any evidence for this argument and relies solely on rhetoric untethered to the record. For example, AAI argues:
Submission of the Fan Fourth Declaration after the May 2012 deadline for Plaintiffs expert reports was substantially justified because, as the Fan Fourth Declaration itself shows, any delay in submitting the Fan Fourth Declaration was caused by Defendants’ longstanding, detailed, carefully-knit fraud. Defendants covered their tracks. Fan Fourth Declaration ¶¶ 6-16. They produced in discovery fabricated evidence, destroyed some key documents during this litigation, withheld others, and submitted false or misleading testimony. They massively altered or tampered with such evidence as they did produce in discovery, including sequence development and testing files. Defendants created out of whole cloth all of their alleged sequences, including the alleged 1,000 path sequence supposedly used for production purposes during 1999-2006. Fan Fourth Declaration, Sections A-D.
(AAI Mem. at 12 (footnote omitted)). Although the foregoing alleges very serious wrongdoing, AAI does not identify any evidence, first produced after May 2012, that necessitated (or even justified) the Fourth Fan Decl. The paragraphs from the Fourth Fan Decl. cited in the foregoing passage— paragraphs 6-16 — actually refer to evidence produced in 2007, five years before the deadline for the production of AAI’s expert reports (Fourth Fan Decl. ¶ 7).
In the single instance in which AAI does cite specific evidence that it claims was first produced after May 2012, the record demonstrates that the information has been in the record for years. AAI cites testimony from Richard Isenberg, first provided in 2012, admitting that Defendants used The Yield Book to value mortgage-backed securities and to adjust their hedges. AAI goes on to argue that this “new evidence” lead Dr. Fan to an epiphany: “On the basis of these disclosures, Dr. Fan then discovered that Defendants’ code did not even have the ability to hedge MBS until shortly after the last test of ACE, when Defendants stole ACE” (AAI Mem. at 8-9 & n. 1, 21). However, as Defendants note, their use of the Yield Book for hedging purposes was disclosed in deposition testimony taken in this action in 2007 (Reply Declaration of Nicholas R. Fung, Esq., dated August 7, 2013 (Docket Item 232), Ex. 1 at Tr. p.9).
Finally, AAI argues that the difficulty of the subject matter prevented it from submitting the Fourth Fan Deck in a timely manner (AAI Mem. at 13, 21). The subject matter of this ease is, without question, difficult. Nevertheless, the case has been pending for nearly 10 years, and the expert deadline was set after 8 years of discovery. Regardless of the difficulty of the subject matter, AAI had more than enough time to get its expert disclosures in on time.
AAI’s unjustifiable failure to serve its expert disclosures on time taints the Fourth Fan Deck as a whole, and justifies the imposition of a sanction, pursuant to (1) Rules 16(f) and 37(b)(2)(A) and (2) my inherent authority to manage this case. See Rule 16(f); Rule 37(b)(2)(A); see also Chambers v. NASCO, Inc., supra, 501 U.S. at 44, 111 S.Ct. 2123 (“[I]t is firmly established that ‘[t]he power to punish for contempts is inherent in all courts.’ ” (citation omitted)); Mitchell v. Lyons Prof'l Servs., Inc., 708 F.3d 463, 467 (2d Cir.2013) (“Every district court ‘has the inherent power to supervise and control its own proceedings and to sanction counsel or a litigant for ... disobeying the court’s orders.’ ” (citations omitted)).
I conclude that preclusion of the Fourth Fan Deck, is the appropriate sanction to the extent AAI relies on it to oppose Defendants’ motion for summary judgment because the Fourth Fan Deck was served in violation of *39the Scheduling Order and constitutes a backdoor attempt to offer new theories and opinions and to re-submit, without any explanation or justification, the previously excluded Fan Reply, which was itself ordered stricken on grounds of delay and impropriety. See United Magazine Co., Inc. v. Curtis Circulation Co., 279 Fed.Appx. 14, 18 (2d Cir.2008) (affirming district court’s decision to strike a previously stricken expert report, submitted with plaintiffs opposition papers); Softel, Inc. v. Dragon Med. & Scientific Commc’ns, Inc., 118 F.3d 955, 961-63 (2d Cir.1997) (affirming magistrate judge and district judge’s order to preclude expert reports submitted past discovery cutoff date); Mobileye, Inc. v. Picitup Corp., 928 F.Supp.2d 759, 766 (S.D.N.Y.2013) (Rakoff, D.J.) (striking an untimely expert declaration, submitted with plaintiffs opposition papers, that incorporated portions of a previously stricken report); Arnold v. Krause, Inc., 232 F.R.D. 58, 67 (W.D.N.Y.2004) (“Preclusion of a proposed expert’s testimony and report, disclosed in violation of a scheduling order ... [has been held to be] a proper sanction where the tardy expert report is offered in opposition to summary judgment.” (citation omitted)).
b. Violation of Rule 26(a) as Basis for Preclusion
As noted above, although AAI’s Rule 26(a)(2) disclosures were due on May 17, 2012, AAI did not serve the Fourth Fan Deck until June 6, 2013, more than a year later. Despite this delay, AAI claims that the Fourth Fan Deck can be appropriately considered in opposition to Defendants’ summary judgment motion because it “merely fleshes out and expands upon” theories already disclosed in Fan’s initial reports and, thus, is admissible despite its untimeliness (AAI Mem. at 18). See Cedar Petrochemicals, Inc. v. Dongbu Hannong Chem. Co., supra, 769 F.Supp.2d at 279 (“[T]o the extent that an expert affidavit is within the scope of the initial expert report, it is properly submitted in conjunction with dispositive motions even outside the time frame for expert discovery.” (citation omitted)). Defendants contend that the Fourth Fan Decl. is not merely a restatement of Dr. Fan’s timely served report because it sets forth new theories that were not previously disclosed and that are based on materials Plaintiff had in its possession for years.2
Plaintiffs characterization of the opinions in the Fourth Fan Decl. is plainly misleading. Fan’s initial expert report, second declaration, and supplemental report all failed to identify the putatively stolen sequences in the material produced by Defendants (see Exhibits B, E, G to the Declaration of Kimberly M. Walker, dated June 6, 2013 (“Walker Decl.”) (Docket Item 219)). In fact, it appears that prior to the Fourth Fan Deck, Dr. Fan did not even attempt to compare Defendants’ sequences or the code in Defendants’ materials to the purportedly misappropriated sequences (see Walker Deck, Ex. E ¶ 90). However, in the Fourth Fan Deck, Fan now contends that he has identified certain codes in Defendants’ materials that were created to steal and surreptitiously use AAI’s trade secret. Indeed, AAI’s opposition to the pending motion repeatedly admits that the Fan Fourth Deck contains new material:
AAI Mem. at 3: “[ W]hile the Fan Fourth Declaration contains some expanded opinions and revelations, these could not previously have been advanced by Dr. Fan as a results of Defendants’ continuing fraud.”
AAI Mem. at 14: “While Plaintiff and Dr. Fan were aware of some pieces of the puzzle and raised various issues with Defendants and the Court over the course of the discovery period, only with the Fan Fourth Declaration was Dr. Fan finally able to piece together all the underlying evidence for the entire scheme.”
AAI Mem. at 17: “Despite its claims elsewhere that the Fan Fourth Deck adds nothing new to Dr. Fan’s previous submissions, AAI claims that “precluding the Fan Fourth Declaration could be devastating to Plaintiffs case, including Plaintiffs opposition to summary judgment.”
*40AAI Mem. at 18: “The Fan Expert Declaration cites new material and offers opinions relating thereto. . . .”
The theories and opinions set forth in the Fourth Fan Deel. clearly are not within the scope of Dr. Fan’s prior reports. Rather, this “wholly new and complex approach” is unquestionably “designed to fill a significant and logical gap” in Dr. Fan’s past reports, in contravention of the expert disclosure requirements. Point Prods. A.G. v. Sony Music Entm’t, 93 Civ. 4001(NRB), 2004 WL 345551 at *9 (S.D.N.Y. Feb. 23, 2004) (Buchwald, D.J.). Because the Fourth Fan Deel. goes beyond Dr. Fan’s timely produced expert disclosures, AAI has violated 26(a)(2) by failing to timely disclose a written “report [that] contain[s] a complete statement of all opinions the witness will express.” Fed. R.Civ.P. 26(a)(2)(B)(i).
AAI’s violation of Rule 26(a)(2)(B)(i) does not end the analysis. I now turn to the four factors relevant to determining whether the sanction sought by Defendants — preclusion— is the appropriate sanction. See Patterson v. Balsamico, supra, 440 F.3d at 117.
i. Explanation for Noncompliance
AAI contends that its belated submission of the Fourth Fan Deel. is justified because Defendants committed fraud throughout discovery and the materials in this case are complex and voluminous and, therefore, time-consuming to analyze (AAI Mem. at 12-14). AAI’s explanations are not persuasive.
At least as far back as 2007, AAI has accused Defendants of destroying and withholding relevant evidence, and it has used this argument to seek additional discovery (see, e.g., Letter from AAI’s counsel to the undersigned, dated September 19, 2007, at 8 (requesting development code materials in order to determine whether “Defendants ginned up phony sequences to provide a defense in this action”)). Indeed, AAI offered this same excuse to justify its belated submission of the now-stricken Fan Reply; at that time, I found that there was “very, very little evidence, if any evidence” that Defendants had committed fraud during discovery (Tr. of Discovery Conference, held on September 5, 2012 (Docket Item 175), at 94). Despite the seriousness of its charges, AAI has not yet sought spoliation sanctions. See In re Motel 6 Secs. Litig., 161 F.Supp.2d 227, 243 (S.D.N.Y.2001) (Keenan, D.J.) (striking expert affidavit, submitted with summary judgment motion, and finding defendant’s excuse that plaintiffs had stonewalled defendant’s requests for discovery and had hidden information to be unconvincing because defendant had sufficient time to address these putative deficiencies before the end of discovery). Having carefully reviewed and considered AAI’s claims that fraud occurred, I find that the record does not support such a conclusion, and it is, thus, not a valid excuse for AAI’s untimeliness.3
AAI next argues that the delay is excusable given the complexity and volume of the materials in this case. However, “[i]f an expert’s report ‘does not rely [on] any information that was previously unknown or unavailable to him,’ it is not an appropriate supplemental report under Rule 26.” Cedar Petrochemicals, Inc. v. Dongbu Hannong Chem. Co., supra, 769 F.Supp.2d at 278 (citation omitted). Here, the Fourth Fan Deck is based entirely on materials that have been in AAI’s possession for well over a year; some materials have been in its possession for nearly seven years. AAI’s explanation is further weakened by its admission that Fan is a “very, very busy [and] very, very expensive” expert and, thus, AAI had only been in touch with him “a few times” preceding the close of discovery (Tr. of Discovery Conference, held on July 18, 2012 (Docket item 226), at 38-39). It should be obvious, however, that if a retained expert lacks the time to comply with the schedule set by the Court, the party should retain another expert. Because AAI had sufficient time to review the materials, this explanation is also not persuasive. See Softel, Inc. v. Dragon Med. & Scientific Commc’ns, Inc., supra, 118 F.3d at *41961-63 (affirming magistrate judge and district judge’s decisions to preclude expert reports submitted after the close of discovery, despite plaintiffs explanation that its expert did not have sufficient time to review the materials).
Accordingly, I find that this factor weighs in favor of preclusion.
ii. Importance of Fourth Fan Decl.
AAI argues that the opinions and evidence set forth in the Fan Fourth Decl. are “crucial” to its ease and that preclusion would be “devastating” (AAI Mem. at 13,17).4
From this Court’s perspective, [plaintiffs] argument only selves to underscore the inexcusable quality of its delayed submission. In this regard it must be noted that this is not a ease in which a new or previously unknown event has recently come to light. Rather, what we have here is an eleventh hour effort to rescue a deficient expert report that has been the basis for the course of this litigation.
Point Prods. A.G. v. Sony Music Entm’t, supra, 2004 WL 345551 at *11; accord Mor-ritt v. Stryker Corp., supra, 2011 WL 3876960 at *7. “Put simply, experts are not free to continually bolster, strengthen, or improve their reports by endlessly researching the issues they already opined upon, or to continually supplement their opinions.” Sandata Techs., Inc. v. Infocrossing, Inc., 05 Civ. 09546(LMM)(THK), 06 Civ. 01896(LMM)(THK), 2007 WL 4157163 at *6 (S.D.N.Y. Nov. 16, 2007) (Katz, M.J.). Accordingly, although an expert’s opinion is clearly important to a case as technical as this one, because Fan has already submitted three prior reports and provided testimony through depositions (see Exhibits B, E, G and SSSS to the Fourth Fan Decl.), I consider this factor to be, at best, neutral.
iii. Prejudice to Defendants
Permitting AAI to utilize the Fourth Fan Decl. in response to Defendants’ summary judgment motion would result in severe prejudice to Defendants. Absent preclusion, discovery will need to be re-opened in order to provide Defendants with an opportunity to explore Fan’s new “revelations” (AAI Mem. at 3) that were not previously advanced, “rendering [Defendants’ summary judgment] motion, addressed in good faith to the theories and evidence that had been disclosed, an expensive waste of effort.” Every v. Makita U.S.A., Inc., 02 Civ. 8545(GEL), 2005 WL 2757952 at *6 (S.D.N.Y. Oct. 24, 2005) (Lynch, D.J.); accord Point 4 Data Corp. v. Tri-State Surgical Supply & Equip., Ltd., 11-CV-726 (CBA), 2013 WL 4409434 at *15 (E.D.N.Y. Aug. 2, 2013) (Report & Recommendation) (prejudice significant where court would need to reopen discovery to allow supplemental expert discovery, thereby burdening defendant with additional costs, including having to resubmit a motion for summary judgment), adopted as modified, 2013 WL 5502852 (E.D.N.Y. Oct. 1, 2013); Morritt v. Stryker Corp., supra, 2011 WL 3876960 at *7 (“[T]he prejudice to defendants of admitting [expert’s untimely report] would be ‘severe, as discovery would have to be reopened’ to permit additional expert reports and depositions.” (citations omitted)); Fleming v. Verizon N.Y., Inc., 03 Civ. 5639(WHP), 2006 WL 2709766 at *8 (S.D.N.Y. Sept. 22, 2006) (Pauley, D.J.) (“[Defendant] would be prejudiced by the admission of the [expert] declarations, because it made its motion for summary judgment based on what it thought to be all of the evidence accumulated in discovery.”).
Hence, this factor, too, weighs in favor of preclusion.
iv. Possibility of a Continuance
Finally, a continuance is not appropriate, given the age of this case and the fact that discovery has long been closed. Morritt v. Stryker Corp., supra, 2011 WL 3876960 at *7 (“[T]he fact that discovery is closed and this case has been pending for over four years Veighs strongly against the possibility of a continuance.’ “ (citations omitted)); Point *42Prods. A.G. v. Sony Music Entm’t, supra, 2004 WL 345551 at *13 (“[Exclusion of the newly offered evidence, and not a continuance of discovery, is now the proper resolution in this decade old action.”); Emmpresa Cubana Del Tabaco v. Culbro Corp., 213 F.R.D. 151, 159 (S.D.N.Y.2003) (Sweet, D.J.) (concluding that “a continuance [was] not a reasonable possibility” where the case had been ongoing for six years). Plaintiff argues that a continuance is possible because a trial date has not yet been established (AAI Mem. at 17). This fact does not alter the analysis since the “expeditious management of discovery schedules is especially important in cases of [technical] nature because they require extensive expert involvement over lengthy periods of time.” Softel, Inc. v. Dragon Med. & Scientific Commc’ns, Inc., supra, 118 F.3d at 962 (denial of a continuance was appropriate even though no trial date had yet been set).
v. Summary
Three of the four Patterson factors weigh in favor of precluding the Fourth Fan Deel. and the remaining factor is neutral. Despite the potential importance of the Fourth Fan Deel., “the exclusion of that testimony results wholly from [Plaintiffs] own failures” Point 4 Data Corp. v. Tri-State Surgical Supply & Equip., Ltd., supra, 2013 WL 4409434 at *16 (inner quotation marks and citation omitted). Hence, on balance, I find that preclusion is, therefore, the appropriate remedy to the extent that AAI is seeking to use the Fourth Fan Deel. to oppose Defendants’ summary judgment motion or in connection with any other dispute involving the merits of the claims and defenses. See Atlantis Info. Tech. v. CA, Inc., 06-CV-3921 (JS)(ETB), 2011 WL 4543252 at *13 (E.D.N.Y. Sept. 28, 2011) (precluding expert testimony where defendant’s explanation for failing to submit an expert report was inadequate and permitting such testimony would delay the case and reopen discovery); Morritt v. Stryker Corp., supra, 2011 WL 3876960 at *7 (precluding evidence despite “the great importance of [expert’s] testimony” in the case); Spotnana, Inc. v. Am. Talent Agency, Inc., 09 Civ. 3698(LAP), 2010 WL 3341837 at *2 (S.D.N.Y. Aug. 17, 2010) (Preska, D.J.) (“These three factors outweigh the importance of [defendant’s] damages evidence, even though [defendant] may be denied any recovery as a result, because [defendant] has disregarded its discovery obligations without any explanation at all.”).
Accordingly, because AAI’s untimely submission of the Fourth Fan Deck was neither substantially justified nor harmless and because the majority of the material factors weigh in favor of preclusion, AAI is precluded from using the Fourth Fan Deck with respect to the merits of the case. For the same reasons and because they were also not timely disclosed, I further order that AAI is precluded from using Exhibits WW, CCC and SSS to the Fourth Fan Deck with respect to the merits of the case. See Rule 26(a)(2)(B)(iii) (requiring expert’s initial disclosure to include any exhibits the expert will use). AAI’s application to submit an amended response to Defendant’s motion for summary judgment is granted; AAI is directed to serve and file its amended response within thirty days of the date of this Order.
2. Use of the Fourth Fan Deel. for Purposes Other than the Merits
To the extent AAI seeks to use the Fourth Fan Deck to respond to Defendants’ Rule 702/Daubert motion and in support of its contemplated motion for sanctions, I conclude that preclusion as a result of AAI’s failure to comply with my scheduling Order or the requirements of Rule 26(a)(2) would lead to unjust results. I do not believe that Rule 26(a)(2)’s requirements should be applied when expert testimony or affidavits are offered for purposes other than the merits of a claim or defense.
In most cases, merits-related issues are capable of being known from the inception of the case. In this case, for example, the issue of Defendants’ alleged misappropriation of AAI’s sequences has always been in the case, and the parties’ need to secure expert testimony to address that issue has always been known to them. Because the issue was always identifiable, the parties knew the issues that needed to be addressed at the time the Rule 26(a)(2) disclosures were due.
*43Non-merits-related issues, such as the admissibility of expert testimony or whether an adversary has engaged in discovery misconduct, stand on a different footing. For example, although Rule 26(a)(2)(B)(iv) requires disclosure of an expert’s qualifications, the Rule does not require that the disclosures address the reliability of the principles and methods used or the reliability of the manner in which those principles and methods were applied in the case. See Fed.R.Evid. 702(c)-(d) (permitting expert testimony that “is the product of reliable principles and methods [that have been] reliably applied ... to the facts of the case”). Challenges to either side’s expert based on a failure to meet the requirements of Rule 702, in most cases, cannot be made until after the Rule 26(a)(2) disclosures have been made. To conclude that expert disclosures used in connection with a Rule 702/Daubert motion or used for other non-merits purposes must comply with Rule 26(a)(2)’s disclosure requirements would create a standard with which compliance is impossible because the non-merits issues could not be known at the time the Rule 26(a)(2) disclosures are required.
The chronology in this case demonstrates the problem. AAI’s 26(a)(2) disclosures were due on May 17, 2012. Defendants served their Rule 702/Daubert motion on or about April 5, 2013. AAI could not have foreseen the Rule 702/Daubert issue that Defendants would raise 11 months before those issues were first asserted.
Accordingly, I conclude that the requirements of Rule 26(a)(2) do not apply to expert reports or expert testimony or affidavits to the extent such material is used for non-merits purposes. Accord Zeolla v. Ford Motor Co., 09-40106-FDS, 2013 WL 308968 at *10-* 11 (D.Mass. Jan. 24, 2013); Lyman v. St. Jude Med. S.C., Inc., 580 F.Supp.2d 719, 725 n. 3 (E.D.Wis.2008); see Celebrity Cruises Inc. v. Essef Corp., 434 F.Supp.2d 169, 190 (S.D.N.Y.2006) (Francis, M.J.).
The foregoing conclusion does not, however, end the issues raised here with respect to the Fourth Fan Deel. My conclusion that neither the Rule 16 Scheduling Order nor Rule 26(a)(2)’s disclosure requirements apply to the Fourth Fan Decl. does not, of course, mean that all of it can be considered for all purposes. Zeolla v. Ford Motor Co., supra, 2013 WL 308968 at *10—*11. The only portion of the Fourth Fan Deel. that responds to Defendants’ Rule 702/Daubert motion is Section G, ¶¶ 257-73; that portion, and only that portion, of the Fourth Fan Decl. can properly be considered in connection with AAI’s response to Defendants’ Rule 702/Daubert motion.
To the extent that AAI seeks to use the Fourth Fan Decl. in support of a motion for sanctions, AAI’s proposed use is grossly untimely. All discovery in this matter closed on July 17, 2012 (Order dated January 19, 2012 (Docket Item 143) ¶ 3).
At the conference held on January 17, 2012, I instructed counsel to raise discovery issues promptly (Tr. of Discovery Conference, held on January 17, 2012 (Docket Item 146), at 78). Even if I deem AAI’s sanctions motion to have been made when AAI served the Fourth Fan Decl. on or about June 4, 2013 — the earliest date possible — the motion was still not made until 11 months after the close of discovery.
Where a party seeks to make a discovery motion after the close of discovery, that party must show good cause. As explained in Gucci America, Inc. v. Guess?, Inc., 790 F.Supp.2d 136, 139-40 (S.D.N.Y.2011) (Cott, M.J.):
Under Rule 16(b), district courts are required to enter scheduling orders “that limit the parties’ time to complete discovery.” McKay v. Triborough Bridge & Tunnel Autt., No. 05 Civ. 8936(RJS), 2007 WL 3275918, at *1 (S.D.N.Y. Nov. 5, 2007). Reopening discovery after the discovery period has closed requires a showing of good cause. Gray v. Town of Darien, 927 F.2d 69, 74 (2d Cir.1991). Though Rule 37 does not establish time limits for such a motion, a party seeking to file a motion to compel after discovery has closed must similarly establish good cause. See, e.g., Eng-Hatcher v. Sprint Nextel Corp., No. 07 Civ. 7350(BSJ) (KNF), 2008 WL 4104015, at *3 (S.D.N.Y. Aug. 28, 2008).
Accord Shah v. Jefferson Parish Sch. Bd., No. 11-2517, 2013 WL 6335874 at *1 *44(E.D.La. Dec. 5, 2013). Given the age of this matter, the fact that the Fourth Fan Decl. does not rely on information first produced after the close of discovery, my admonition in January 2012 that discovery disputes be raised promptly and the almost year-long gap between the close of discovery and the earliest date on which a sanctions motion could possibly be deemed to have been made, I conclude that AAI cannot show good cause to make a motion for sanctions at this late date. Thus, the Fourth Fan Decl. cannot be used in support of a motion for sanctions.
3. Attorney’s Fees and Costs
For the reasons set forth above, AAI’s attempt to use the Fourth Fan Decl. was substantially justified only to the extent that it sought to use the document to oppose Defendants’ Rule 102/Daubert motion. Thus, although I find that Defendants are entitled to recover some of their attorney’s fees and costs, they are not entitled to recover 100% of those items. I conclude that Defendants are entitled to recover one-half of the fees and costs incurred in making this motion, pursuant to Rules 16(f) and 37(c). “Monetary sanctions ... may be awarded to compensate for added expense caused by the recusant party’s conduct.” Quadrozzi v. City of New York, 127 F.R.D. 63, 74 (S.D.N.Y.1989) (citation omitted). I find this sanction to be especially appropriate in light of the fact that AAI attempted to re-incorporate the Fan Reply, despite my Order that it be stricken and Judge Swain’s affirmance of that Order. Plaintiffs duplicitous behavior and unjustified submission of the Fourth Fan Decl. served only to delay resolution in a ease that has been ongoing for nearly a decade, and was “wasteful of the time of the Court and opposing counsel.” Dallas v. Goldberg, supra, 2003 WL 22872325 at *1.
Accordingly, AAI and its counsel shall reimburse Defendants for one-half of any expenses, including reasonable attorney’s fees and costs, incurred as a result of AAI’s failure to comply with the Scheduling Order and Rule 26(a)(2). I direct Defendants’ counsel to submit a sworn statement, with supporting documentation, regarding the costs and fees associated with the present motion and justifying the hourly rates.
IV. Conclusion
Accordingly, for all the foregoing reasons, it is hereby ORDERED that:
1. The Fourth Fan Decl. is stricken except to the extent AAI seeks to use paragraphs 257-73 to oppose Defendants’ Rule 102/Daubert motion;
2. Exhibits WW, CCC and SSS to the Fourth Fan Decl. are stricken.
3. Within thirty (30) days of the date of this Order, AAI is directed to serve its amended opposition to Defendants’ motion for summary judgement.
4. Within twenty (20) days of the date of this Order, Defendants are to submit their fee application; AAI shall submit its response twenty (20) days thereafter.
SO ORDERED.

OPINION AND ORDER

I. Introduction
By notice of motion dated April 9, 2014 (Docket Item 236), plaintiff moves for reconsideration or clarification of my Opinion and Order dated March 26, 2014 (Docket Item 235) (“3/26/14 Order”). For the reasons set forth below, plaintiffs motion is denied.
The reader’s familiarity with the 3/26/14 Order is assumed. Stated briefly, that Order granted defendants’ motion to strike an expert declaration — Fourth Declaration of Dr. Jianqing Fan (“Fourth Fan Deck”) — except to the extent that AAI sought to use paragraphs 257-73 of the Fourth Fan Deck to oppose Defendants’ Rule 702/Daubert motion or in support of a sanctions motion contemplated by plaintiff. Plaintiff now seeks a ruling that the Fourth Fan Declaration can be used to impeach certain testimony offered by defendants with respect to the merits of he case.
II. Analysis
As a motion for reconsideration or clarification, plaintiffs motion is procedurally defective. Motions for reconsideration are appropriate only in very limited circumstances. As explained by the Honorable Mi*45chael B. Mukasey, United States District Judge, now retired, in McMahan & Co. v. Donaldson, Lufkin & Jenrette Sec. Corp., 727 F.Supp. 833, 833 (S.D.N.Y.1989):
Motions for reargument “are granted when new facts come to light or when it appears that controlling precedents were overlooked .” Weissman v. Fruchtman, 658 F.Supp. 547 (S.D.N.Y.1987). The proponent of such a motion is not supposed to treat the court’s initial decision as the opening of a dialogue in which that party may then use [Local Civil Rule 6.3] to advance new facts and theories in response to the court’s rulings. The purpose of the rule is “to ensure the finality of decisions and to prevent the practice of a losing party examining a decision and then plugging the gaps of a lost motion with additional matters.” Lewis v. New York Telephone, No. 83 Civ. 7129, slip op. at 2, 1986 WL 1441 (S.D.N.Y.1986) cited in Carolco Pictures Inc. v. Sirota, 700 F.Supp. 169 (S.D.N.Y.1988).
See also Mahmud v. Kaufmann, 496 F.Supp.2d 266, 269-70 (S.D.N.Y.2007) (Conner, D.J.). “A movant for reconsideration bears the heavy burden of demonstrating that there has been an intervening change of controlling law, that new evidence has become available, or that there is a need to correct a clear error or prevent manifest injustice.” Quinn v. Altria Grp., Inc., 07 Civ. 8783(LTS)(RLE), 2008 WL 3518462 at *1 (S.D.N.Y. Aug. 1, 2008) (Swain, D.J.), citing Virgin Airways v. Nat’l Mediation Bd., 956 F.2d 1245, 1255 (2d Cir.1992).

Aug. 4, 1989) (Cannella, D.J.); accord Caribbean Trading & Fid. Corp. v. Nigerian Nat’l Petroleum Corp., 948 F.2d 111, 115 (2d Cir.1991); see also Woodard v. Hardenfelder, 845 F.Supp. 960, 966 (E.D.N.Y.1994) . “These limitations serve to ensure finality and to prevent losing parties from using motions for reconsideration as a vehicle by which they may then plug the gaps of a lost motion with additional matters.” In re City of N.Y., as Owner & Operator of the M/V Andrew J.

Apr. 24, 2003) (Haight, D.J.); Cohn v. Metro. Life Ins., Co., 07 Civ. 0928(HB), 2007 WL 2710393 at *1 (S.D.N.Y. Sept. 7, 2007) (Baer, D.J.); In re Rezulin Prods. Liab. Litig., 224 F.R.D. 346, 349 (S.D.N.Y.2004) (Kaplan, D.J.); Horsehead Res. Dev. Co., Inc. v. B.U.S. Envtl. Servs., Inc., 928 F.Supp. 287, 289 (S.D.N.Y.1996) (Scheindlin, D.J.).
Although I am sure that plaintiff disagrees with my 3/26/14 Order, its present motion does not identify any controlling factual or legal matters that were called to my attention in connection with defendants’ motion to strike the Fourth Fan Decl. and that I overlooked. In its opposition to defendants’ motion to strike the Fourth Fan Deck, plaintiff never even suggested that the Fourth Fan Deck might be admissible for the limited purpose of impeachment. Rather, plaintiff chose to address the admissibility of the Fourth Fan Deck with respect to defendants’ summary judgment motion as an “all-or-*46nothing” proposition, and never suggested that the declaration might be admissible for limited purposes. Because plaintiff is now making a new argument and seeking new relief that it could have (and should have) sought in response to defendants’ motion to strike, its application is not properly brought as a motion for reconsideration or clarification. In re Refco Capital Mkts., Ltd. Brokerage Customer Secs. Litig., 06 Civ. 643(GEL), 07 Civ. 8686(GEL), 07 Civ. 8688(GEL), 2008 WL 4962985 at *1 (S.D.N.Y. Nov. 20, 2008) (Lynch, D.J.) (“A motion for reconsideration is not an opportunity for a losing party to advance new arguments to supplant those that failed in the prior briefing of the issue.”); accord Sahu v. Union Carbide Corp., 04 Civ. 8825(JFK), 2010 WL 909074 at *2 (S.D.N.Y. Mar. 15, 2010) (Keenan, D.J.).
Even if it were not proeedurally defective, plaintiffs motion is nothing more than legal legerdemain. My 3/26/14 Order struck the Fourth Fan Decl. for all purposes, other than its use in plaintiffs opposition to defendants’ Rule 702/Daubert motion or in support of plaintiffs contemplated motion for sanctions, because it was untimely and served in violation of Rule 26(a)(2). Accordingly, I concluded that neither the Fourth Fan Declaration nor the opinions expressed therein could be used in connection with the merits of the case.
In its newly-minted argument, plaintiff claims that it seeks to use the opinions expressed in the Fourth Fan Decl. to impeach defendants’ witnesses.1 Although a witness can be impeached by contradiction, plaintiff is seeking to impeach defendants’ witnesses by contradicting them not on collateral matters but with respect to the merits of the case by offering the very testimony that I precluded in my 3/26/14 Order. Defendants’ testimony would be impeached, however, only if the fact finder credited Dr. Fan’s opinions on merits issues — the precise use that I have already precluded. Plaintiff is merely seeking to do indirectly what I previously ruled it could not do directly.
In support of its argument, plaintiff relies in part on the Eight Circuit’s decision in Wegener v. Johnson, 527 F.3d 687 (8th Cir.2008). However, the decision in that case actually mandates denial of plaintiffs motion. In Wegener, the plaintiff in a medical malpractice case appealed from an adverse judgment, arguing that the trial court erred by excluding testimony from one of plaintiffs experts. Two and one-half weeks before tidal and long after the deadline for expert disclosure, plaintiff served a supplemental expert report. The trial court concluded that the plaintiffs expert could not testify, either as part of plaintiffs direct case or in rebuttal, to the material in the supplemental report. Like plaintiff here, Wegener argued that the opinions in the untimely supplemental report were admissible as impeachment material.
The Eighth Circuit rejected Wegener’s argument, stating:
Rule 26 does not require the disclosure of evidence used solely for impeachment purposes. See Fed.R.Civ.P. 37(c) advisory committee’s note (1993). The district court did not err by concluding that Rule 26(a)(2) required disclosure of Dr. Hal-bridge’s supplemental testimony, however, because it is not impeachment evidence of the kind exempted from disclosure. Impeachment is “an attack on the credibility of a witness.” Sterkel v. Fruehauf Corp., 975 F.2d 528, 532 (8th Cir.1992). To attack the credibility of witnesses by the presentation of evidence showing that facts asserted or relied upon in their testimony are false is to impeach by contradiction. 27 Charles Alan Wright & Victor James Gold, Federal Practice and Procedure § 6096 (1990). It does not impeach, however, to show that an expert’s opinion about the meaning of facts merely differs from that of other experts. See Kennemur v. California, 133 Cal.App.3d 907, 184 Cal.Rptr. 393, 402 (1982). It is often difficult to distinguish between foundational facts and expert opinion, and so to distin*47guish between impeachment and substantive evidence, see id. at 403, but Rule 26(a)(2)(C)(ii) resolves the dilemma in favor of disclosure by requiring parties to disclose expert testimony offered to contradict the expert testimony of the opposing party. Because Wegener offered Dr. Halbridge’s supplemental testimony to contradict the testimony of Johnson’s experts, she was required to disclose it.
527 F.3d 690-91.2
Thus, because it is procedurally defective and fails on the merits, plaintiffs motion is denied.3
III. Conclusion
Accordingly, for all the foregoing reasons, plaintiff motion for reconsideration/elarification is denied in all respects. The Clerk of the Court is directed to mark Docket Item 236 closed.
SO ORDERED.

. A comprehensive recitation of the events giving rise to this action is set forth in my 2009 Report and Recommendation addressing the parties’ motions for summary judgment. Advanced Ana-lytics, Inc. v. Citigroup Global Mkts., Inc., 04 Civ. 3531 (LTS)(HBP), 2009 WL 7133660 (S.D.N.Y. Aug. 5, 2009) (Report & Recommendation), adopted in part, rejected in part, 2010 WL 4780772 (S.D.N.Y. Nov. 22, 2010)

. Without citing any authorities, AAI claims that it is incumbent on Defendants to identify the specific portions of the Fourth Fan Decl. that go beyond Dr. Fan’s prior, timely submissions. I disagree. Where, as here, a party attempts to make an expert submission more than a year after its due date, and in clear violation of a scheduling order, the party offering the material bears the burden of demonstrating justification for the untimely submission.

. For purposes of analyzing plaintiff's proffered explanation, I have also carefully reviewed the allegations of fraud set forth in the Fourth Fan Deel. and the accompanying exhibits. I do not find Fan’s conclusion that fraud occurred to be persuasive; much of Fan’s analysis appears to be speculative while the relevant exhibits lack the foundation necessary to be reliable.

. AAI’s contention that the contents of the Fourth Fan Decl. are “crucial” to its case and that preclusion would be "devastating” is a compelling admission that the Fourth Fan Decl. contains new material. If the Fourth Fan Decl. merely repeated Dr. Fan’s previously-stated opinions and theories, its exclusion could not be devastating because the same testimony would come in on the basis of Dr. Fan’s previously issued reports.

. Plaintiff has identified 10 paragraphs of the Fourth Fan Decl. as constituting impeachment material. The Fourth Fan Decl. is 274 paragraphs and 91 pages long. It is accompanied by 117 exhibits (Ex. A though Ex. MMMMM) which are approximately 12 inches thick. Plaintiff makes no effort to explain how the remaining 264 paragraphs and the exhibits constitute impeachment material.

. It is doubtful that much of the testimony plaintiff seeks to offer from Dr. Fan would be admissible, even as impeachment material. In connection with my 3/26/14 Order, I carefully reviewed the Fourth Fan Deck, and a substantial portion of it is nothing more than Dr. Fan’s opinion concerning the meaning of the evidence revealed in discovery, untethered to his expertise as a mathematician. For example, in its present motion, plaintiff seeks to offer testimony from Dr. Fan that Robert Russell is the author of the computer code that allegedly stole plaintiff’s putative trade secret — a sequence of numbers (Plaintiff’s Memorandum of Law in Support of Plaintiff’s Motion for Clarification or in the Alternative Reconsideration of a Discrete Portion of the Court’s Opinion and Order of March 26, 2014, dated April 9, 2014 (Docket Item 238) at 3-4). There is no relationship between mathematical expertise and the ability to divine the authorship of a putative segment of computer code. Offering a mathematician to give such testimony would violate the requirement that “the field of expertise claimed by the expert [be] known to reach reliable results for the type of opinion the expert would give.” Krause v. CSX Transp., No. 1:1 l-CV-0098 (GTS/RFT), 2013 WL 6163990 at *9 (N.D.N.Y. Nov.20, 2013), citing Fed.R.Evid. 702, Advisory Committee Notes to the 2000 Amendments; see Kumho Tire Co. v. Carmichael, 526 U.S. 137, 149, 119 S.Ct. 1167, 143 L.Ed.2d 238 (1999). Plaintiff nowhere explains how Dr. Fan's expertise in mathematics qualifies him to express an opinion concerning the authorship of a particular segment of computer code or how mathematical techniques yield reliable results on the issue of the authorship of computer code. The Fourth Fan Deck contains nothing to establish the connection. Because there is no relationship between Dr. Fan’s expertise and at least some of the testimony plaintiff seeks to elicit from him, such testimony would not even be admissible as impeachment testimony.

. Defendants seek an award of attorney’s fees in their opposition to plaintiff’s motion. As a matter of discretion, the application is denied.
