UNITED STATES DISTRICT COURT SOUTHERN DISTRICT OF NEW YORK wn KX NAULA NDUGGA, : Plaintiff, : OPINION AND ORDER ~V.- : 20 Civ. 7464 (GHW) (GWG) BLOOMBERG L.P., : Defendant. : wn KX GABRIEL W. GORENSTEIN, United States Magistrate Judge: Plaintiff Naula Ndugga has sued defendant Bloomberg L.P. (“Bloomberg” or “BLP”’) for violations of Title VII of the Civil Rights Act of 1964, 42 ULS.C. § 20006¢ et seq. (“Title VII’) on behalf of a proposed class of news personnel who worked at Bloomberg in 2021, and for violations of the New York State Human Rights Law, N.Y. Exec. Law §§ 290-301 (““NYSHRL”) on behalf of a proposed subclass of news personnel who worked at Bloomberg in 2017 through 2020. See Fifth Amended Complaint, filed July 10, 2024 (Docket #296) (“Compl.”), J 165-96. Bloomberg moves to exclude the opinions and testimony of Ndugga’s expert witness David Neumark.! For the following reasons, Bloomberg’s motion is denied.

' See Notice of Motion, filed Feb. 20, 2025 (Docket # 344); Memorandum of Law in Support of Defendant’s Motion to Exclude the Opinions and Testimony of David Neumark, filed Feb. 20, 2025 (Docket # 345) (“Mem.”); Declaration of Elise M.

The foregoing record citations are to the original unredacted, sealed filings. Redacted versions of each document are filed on the ECF system at Docket ## 421-23

I. BACKGROUND A. Procedural Background At the time suit was brought, Ndugga was a “[n]ews producer” at Bloomberg. Compl. 41. On July 10, 2024, Ndugga filed the operative complaint in which she alleges “systemic sex discrimination in compensation . . . directed from the highest levels at Bloomberg.” Id. The complaint asserts numerous class claims, in addition to claims on her own behalf. See id. 4 165-222. On December 20, 2024, Ndugga filed a motion for class certification.” In the motion, Ndugga sought to certify, for purposes of New York state-law claims, a proposed class of “[a]ll female Reporters, Producers, and Editors who: (1) were not Team Leaders or in other supervisory positions; and (2) were subjected to Defendant’s compensation systems for work performed in New York at any time from August 9, 2017 through December 31, 2020” to pursue New York state law claims. Class Cert. Mem. at 25. She also sought to certify, in order to pursue parallel Title VII claims, a proposed class of “[a]ll female Reporters, Producers, and Editors who: (1) were not Team Leaders or in other supervisory positions, and (2) were subjected

See Notice of Plaintiff’s Motion for Class Certification, filed Dec. 20, 2024 (Docket # 329); Memorandum of Law in Support of Plaintiff’s Motion for Class Certification, filed Dec. 20, 2024 (Docket # 330) (“Class Cert. Mem.”); Declaration of Dana Busgang in Support of Plaintiff’s Motion for Class Certification, filed Dec. 20, 2024 (Docket # 333) (“Busgang Decl.”); Memorandum of Law in Opposition to Plaintiff’s Motion for Class Certification, filed June 23, 2025 (Docket # 379) (“Class Cert. Opp.”); Reply Memorandum of Law in Support of Plaintiff’s Motion for Class Certification, filed July 14, 2025 (Docket # 385) (“Class Cert. Reply’); Sur- Reply Memorandum of Law in Opposition to Plaintiff’s Motion for Class Certification, filed July 18, 2025 (Docket # 395) (“Class Cert. Sur-Reply”); Letter from Mark W. Batten, dated Aug. 27, 2025 (Docket # 406); Letter from Christine E. Webber, dated Sept. 10, 2025 (Docket # 411). The foregoing record citations are to unredacted, sealed filings.

to Defendant’s compensation systems for work performed in the United States at any time from February 3, 2021 through December 31, 2021.” Id. at 26. In the memorandum of law accompanying the motion, Ndugga relied heavily on an expert report authored by Dr. David Neumark, see, e.g., id. at 19-22, particularly in order to “satisfy the commonality requirement” of Rule 23, see id. at 33-35.° On February 11, 2025, defendant requested permission to file a motion to exclude the opinions and testimony of Neumark from consideration in connection with Ndugga’s motion for class certification under the principles of Daubert v. Merrell Dow Pharms., Inc., 509 U.S. 579 (1993). See Letter, filed Feb. 11, 2025 (Docket # 340). Finding that Ndugga relied heavily on Neumark’s opinions in support of the motion for class certification, the Court initially determined that it would be best to resolve the admissibility of those opinions before the parties submitted any more briefs in connection with the class certification motion. See Order, dated Feb. 12, 2025 (Docket # 343). After the Daubert motion was fully briefed, however, the Court changed course and determined that it would be best to decide the Daubert motion in conjunction with the class certification motion. See Order, dated June 9, 2025 (Docket # 374). Both motions are now fully briefed. B. Dr. Neumark’s Opinion Neumark is a labor economist holding the position of “Distinguished Professor of Economics at the University of California-Irvine.” Neumark Decl. § 1. Neumark was retained by plaintiff “to evaluate evidence of pay discrimination against women . . . at Bloomberg.” Id. 4 2.

> See Expert Report of David Neumark, dated July 1, 2024, annexed as Ex. 66 to Busgang Decl. at *4-*60 (Docket # 333-66) (“Neumark Report”); Declaration of David Neumark, dated July 1, 2024, annexed as Ex. 66 to Busgang Decl. at *2-*3 (Docket # 333-66).

1. Neumark’s Original Report Neumark used “data produced by Bloomberg that contain employment history and compensation records for the employees in the proposed Classes” to “construct a dataset of annual employee records.” Neumark Report {ff 9, 10. Neumark analyzed that data to “compare | compensation at Bloomberg for similarly-situated female and male employees.” Id. 4 12. “In addition to pay, the data” used by Neumark “include[d] an indicator for the gender of an employee, and characteristics of the individuals and their jobs.” Id. Neumark analyzed the data using a regression model to “estimate[] the female pay penalty (if there is one) once we adjust for possible differences between female and male employees that could account for a pay gap between women and men.” Id. §/ 13. As Neumark explains, For example, suppose that we simply compare average pay of all female and male employees at Bloomberg, and find that average pay of female employees is 10% lower. It is possible that women do different jobs, and those jobs could pay less. It is also possible that women and men are in broadly similar jobs, but the women have lower performance. In either case, our intuition would be that the 10% estimate overstates the pay gap for comparable women and men in comparable jobs, and we should hence adjust for these differences between women and men before estimating the female pay penalty.
