*77 OPINION

CBF Trucking appeals the District Court’s decision confirming the arbitration award entered against CBF and in favor of Michael Miekens, a CBF-employed member of the International Brotherhood of Teamsters, Local 701 union. We will affirm. 1

CBF provides shipping services to the United States Postal Service. On November 25, 2008, Miekens failed to perform an assigned pick-up and delivery. Following CBF’s investigation, it called a meeting with Miekens and his union representatives at which Miekens insisted he had completed the assigned run. Notwithstanding his insistence, CBF concluded that Miekens failed to complete the assignment and, on that basis, terminated Mick-ens. Miekens and the union grieved the termination, leading to a second meeting. Once again, Miekens insisted that he completed the assigned run. CBF was unaware at the time of the meetings that Miekens was tape recording the proceedings.

Pursuant to the collective bargaining agreement, the union filed a demand for arbitration. At the arbitration hearing, Miekens, for the first time, offered an explanation for his failure to perform the assigned trip, asserting that a security guard relayed a message from CBF that he did not need to complete the assignment. The security guard was called to testify and he did not contest Miekens’ explanation, testifying that it was “possible” he had provided such an instruction to Miekens. CBF introduced the minutes from the first meeting which reported Miekens’ initial, and ultimately false, claim that he had completed the assignment. Despite the evidence that Miekens had changed his story and initially lied to CBF, the arbitrator concluded that Miekens was wrongfully terminated and ordered that he be reinstated with full back-pay.

Shortly after issuance of the arbitration award and during discovery in a separate state lawsuit, Miekens produced to CBF the covert recordings he had made of the two meetings between CBF, Miekens, and the union. The union does not contest that the recordings depict Miekens’ original adamancy that he completed the assigned run. The tapes were not produced before this late date despite the fact that CBF had repeatedly requested that Mick-ens and the union produce all relevant documents.

When the union filed the action in the District Court to enforce the arbitration award, CBF moved to vacate the award on the ground that it was procured by fraud or undue means. The District Court denied the motion, holding that while Mick-ens had lied and surreptitiously withheld the tapes, thereby committing fraud, the fraud was not material to the outcome of the arbitration proceeding.

Given the strong presumption in favor of arbitration, federal law provides that a district court may vacate an arbitration award “only under exceedingly narrow circumstances.” Dluhos v. Strasberg, 321 F.3d 365, 370 (3d Cir. 2003). Those circumstances are delineated in the Federal Arbitration Act (“FAA”) itself. Pursuant to Section 10(a)(1) of the FAA, one such circumstance is when the award was “procured by corruption, fraud, or undue means.” Courts have applied a three-part *78 test to determine whether an award was procured by fraud. Under the test, CBF must establish (1) the existence of fraud by clear and convincing evidence, (2) that the fraud was not discoverable with the exercise of due diligence, and (3) that the fraud materially relates to an issue in the arbitration. See, e.g., A.G. Edwards & Sons, Inc. v. McCollough, 967 F.2d 1401, 1404 (9th Cir. 1992); Bonar v. Dean Witter Reynolds, Inc., 835 F.2d 1378, 1383 (11th Cir. 1988).

Applying this test, the District Court correctly concluded that “Mickens’ failure to provide CBF with the tape recordings until after the arbitration award had been finalized is fraudulent or undue conduct that could be grounds for vacating the arbitration award.” Int’l Bhd. of Teamsters, Local 701 v. CBF Trucking, Inc., No. 09-5525, 2010 WL 2400400, at *2, 2010 U.S. Dist. LEXIS 57386, at *6 (D.N.J. June 10, 2010). However, as the District Court noted, the arbitrator was already aware of the essential facts contained on the tapes — that is, that Mickens originally lied and insisted that he completed the job assignment. Accordingly, the District Court did not err in reasoning that the recordings were not material to the arbitrator’s decision and their nondisclosure did not deprive CBF of a fair proceeding. See Envtl. Barrier Co., LLC v. Slurry Sys., Inc., 540 F.3d 598, 608 (7th Cir. 2008) (there must be “a nexus between the purported fraud and the arbitrator’s final decision”). 2

For the foregoing reasons and substantially for the reasons explained in the District Court’s opinion, we will affirm the judgment of the District Court.
