OPINION

David E. Welch appeals a final order of the Administrative Review Board (ARB) finding that his discharge by Cardinal Bankshares Corporation did not violate the whistleblower protection provision of the Sarbanes-Oxley Act. For the reasons set forth within, we affirm.

I.

Cardinal Bankshares Corporation is a bank holding company with its common stock listed on the NASDAQ Bulletin Board. As of December 31, 2001, Cardinal had outstanding over 1.5 million shares of common stock, held by approximately 600 stockholders of record. Cardinal is the sole owner of a single financial institution, the Bank of Floyd. Cardinal and the Bank of Floyd share a Board of Directors and managing officers, and Ronald Leon Moore serves as the Chief Executive Officer of both entities. Hereinafter, we refer to the Bank of Floyd and Cardinal interchangeably as “Cardinal.”

Welch, the petitioner in this case, is licensed as a certified public accountant in Virginia and holds a bachelor’s and a master’s degree in business administration. Welch began working for Cardinal in 1999 as a part-time accounting officer, and, in 2000, Moore hired Welch as Cardinal’s Chief Financial Officer (CFO). Welch’s responsibilities as CFO of Cardinal included preparing and reviewing entries on Cardinal’s general ledger accounts; devising and implementing accounting procedures; and preparing various reports and financial statements, including the 10-QSB quarterly reports and 10-K annual reports that Cardinal is required to submit to the Securities and Exchange Commission (SEC), see 15 U.S.C. §§ 78Z-78m (2000).

Welch came to believe that Cardinal’s accounting practices were seriously deficient in several respects. According to Welch, Moore and others who lacked accounting expertise routinely made entries in Cardinal’s general ledger; Welch asserts that this practice itself violated generally accepted accounting principles (GAAP). He also contends that this practice resulted in ledger entries that violated GAAP.

Most notably, on one specific occasion, Cardinal recovered two loans that it had previously written off, expecting that they would not be recouped. Cardinal recorded the unexpected recovery of these written-off loans, totaling $195,000, as income; Welch maintains that GAAP does not permit such recovered loans to be reported as income and instead requires that they be listed on a company’s loan reserve account. Welch attempted to change the ledger entries so that the loans would be recorded in the loan reserve account instead of as income, but Moore refused to authorize these changes. According to Welch, these incorrect entries caused Cardinal to overstate its year-to-date income by $195,000 in its 2001 third-quarter 10-QSB report to the SEC. Larrowe & Co., PLC, Cardinal’s independent auditor, eventually corrected these entries in Cardinal’s annual report during the 2001 year-end audit, but neither Cardinal nor Larrowe & Co. ever submitted a corrected third-quarter 10-QSB report to the SEC.

Finally, Welch claims that Moore would often communicate directly with Larrowe & Co. about financial matters without including Welch. Welch alleges that by so excluding him, Moore restricted his access[*273] to Larrowe & Co., and that this “restricted access” prevented him from performing his tasks as CFO and prevented him from confirming the accuracy of Cardinal’s financial reports.

Welch forcefully communicated his concerns about these assertedly improper accounting practices in multiple formal mem-oranda to Moore and others immediately following the July 30, 2002, effective date of the Sarbanes-Oxley Act of 2002, Pub.L. No. 107-204, 116 Stat. 745. Welch also contends that he raised these concerns orally with Moore and others as they arose in 2001. ^[1]

On August 2, 2002, Welch informed Lar-rowe & Co. in writing that he could not sign a representation letter to Larrowe & Go. confirming that Cardinal provided Larrowe & Go. with accurate financial information for the first and second quarters of 2002, because Moore and others had made ledger entries without his supervision and because Moore and Larrowe & Co. had excluded him from their “communications loop” on various issues.

On August 14, 2002, Welch refused to certify Cardinal’s 2002 second-quarter 10-QSB report to the SEC, as required by the Sarbanes-Oxley Act. In a memorandum explaining his refusal to certify the quarterly report, Welch claimed that he could not certify to the accuracy of the company’s financial reports because, among other concerns, unauthorized persons had recorded ledger entries. Welch identified the entry as income of the $195,000 in recovered loans as evidence of the inaccuracies he believed this practice had caused. Moore ultimately certified Cardinal’s quar-teriy report himself, because Welch refused to do so.

On September 13, 2002, Welch submitted another formal memorandum to Moore, insisting that Cardinal needed to change its accounting practices before Welch could certify the pending 2002 third-quarter 10-QSB report to the SEC. Welch again complained about the entry of the $195,000 in recovered loans as income, this time arguing that Cardinal needed to correct its 2001 third-quarter 10-QSB report that listed the $195,000 as income; Welch also repeated his complaints that Moore had excluded him from communications with Larrowe & Co. and that unauthorized persons had made ledger entries.

Following this barrage of criticism, Welch’s relationship with Moore deteriorated rapidly. On September 17, 2002, Moore called a meeting of Cardinal’s Board of Directors to discuss Moore’s dissatisfaction with Welch. Moore related to the Board the content of Welch’s memo-randa and his belief that Welch’s concerns were unfounded. Moore also reported that in August 2002, state examiners had found numerous errors in a quarterly call report that Welch had prepared and submitted to the Federal Reserve and the Virginia State Corporation Commission. In addition, Moore related that the examiners had commented that many of the “charts, graphs, and spreadsheet reports” prepared by Welch were “unnecessary and time-consuming.” Moore advised the Board that “the situation has deteriorated to the point that Mr. Welch seems to have become disaffected and apparently is unwilling or unable to do what needs to be[*274] done to comply with the law.” The Board decided to ask the Audit Committee’s legal counsel, Douglas Densmore, and outside auditor, Michael Larrowe, to investigate and prepare a report on Welch’s assertions, including his claim that Cardinal needed to correct its third-quarter 2001 SEC report because Cardinal had improperly reported the $195,000 in recovered loans as income.

On September 20, 2002, Welch held what he characterized as a “Sarbanes-Ox-ley briefing” for senior personnel at Cardinal. During this briefing, Welch alleged that three Cardinal employees were “parties to fraudulent acts,” outlined his belief that Cardinal’s accounting practices violated the Sarbanes-Oxley Act, and proposed that he leave Cardinal quietly upon receipt of a generous severance package. Following the meeting, Densmore and Larrowe attempted to meet with Welch to discuss his charges, but Welch repeatedly refused to meet with them without his personal attorney.

At a meeting of Cardinal’s Board of Directors on September 25, 2002, the Board voted to suspend Welch without pay pending the results of Densmore and Lar-rowe’s investigation. Following his suspension, the Board ordered Welch to meet with Densmore and Larrowe without counsel to discuss his accusations, but Welch again refused to meet without his attorney.

On October 1, 2002, Densmore and Lar-rowe presented the results of their investigation to the Board. They concluded that Welch’s concerns regarding Cardinal’s accounting practices lacked merit. They also concluded that Welch had seriously breached his fiduciary duty to Cardinal by refusing to meet with them to discuss his charges, and they recommended that Cardinal discharge him. The Board unanimously voted to discharge Welch, effective immediately.

Welch then filed a complaint with the Occupational Safety and Health Administration (OSHA), alleging that Cardinal had dismissed him in violation of the whistle-blower protection provision of § 806 of the Sarbanes-Oxley Act, 18 U.S.C. § 1514A (Supp. V 2005). Welch alleged that his various communications to Cardinal constituted protected activity under the Sar-banes-Oxley Act and that Cardinal fired him because of this protected activity. Based on an investigation by OSHA, the Secretary of Labor dismissed the complaint, finding that, although Welch engaged in protected activity, Cardinal did not fire him because of that activity. Rather, the Secretary found that Cardinal fired Welch because Welch refused to meet with Densmore and Larrowe without counsel, which the Secretary concluded constituted a legitimate reason for Welch’s discharge.

Welch appealed and requested a hearing before an administrative law judge (ALJ). See 29 C.F.R. § 1980.106 (2007). Following the hearing, the ALJ issued a recommended decision and order, finding that at least three of the concerns that Welch communicated to Cardinal constituted protected activity under the Sarbanes-Oxley Act. Specifically, the ALJ found that the Sarbanes-Oxley Act protected Welch’s communications about: (1) Cardinal’s entry of the $195,000 in recovered loans as income; (2) Cardinal’s general practice of allowing persons without accounting expertise to make ledger entries; and (3) Welch’s “restricted access” to Larrowe & Co. The ALJ found that Cardinal fired Welch because of these protected activities and ordered him reinstated with back pay. The ALJ later issued a supplemental recommended decision and order, stipulating the amount of back pay to which the judge found Welch entitled.

[*275] Cardinal appealed the ALJ’s order to the ARB, which reversed, finding as a matter of law that none of Welch’s communications constituted protected activity under the Sarbanes-Oxley Act and dismissing Welch’s complaint. Welch appeals.

II.

The Sarbanes-Oxley Act creates “whis-tleblower” protection for employees of publicly-traded companies by prohibiting employers from retaliating against employees because they provided information about potentially unlawful conduct. Specifically, the Sarbanes-Oxley Act provides:

No [publicly-traded company], or any officer [or] employee ... of such company, may discharge ... an employee ... because of any lawful act done by the employee—

(1) to provide information ... regarding any conduct which the employee reasonably believes constitutes a violation of section 1341 [mail fraud], 1343 [wire fraud], 1344 [bank fraud], or 1348 [securities fraud], any rule or regulation of the [SEC], or any provision of Federal law relating to fraud against shareholders, when the information ... is provided to ...

... a person with supervisory authority over the employee ....

18 U.S.C. § 1514A(a); see also Livingston v. Wyeth, Inc., 520 F.3d 344, 351 (4th Cir.2008); Allen v. Admin. Review Bd., 514 F.3d 468, 475 (5th Cir.2008).

The whistleblower protection provision of the Sarbanes-Oxley Act adopts the burden-shifting framework applicable to whistleblower claims brought under the Wendell H. Ford Aviation Investment and Reform Act for the 21st Century, 49 U.S.C. § 42121(b) (2000). See 18 U.S.C. § 1514A(b). Accordingly, an employee bears the initial burden of making a prima facie showing of retaliatory discrimination; the burden then shifts to the employer to rebut the employee’s prima facie case by demonstrating by clear and convincing evidence that the employer would have taken the same personnel action in the absence of the protected activity. 49 U.S.C. § 42121(b)(2)(B).

The Department of Labor (DOL) regulations implementing § 1514A provide that in order to make a prima facie showing, an employee’s complaint must allege that: (1) the employee engaged in protected activity; (2) the employer knew, actually or constructively, of the protected activity; (3) the employee suffered an unfavorable personnel action; and (4) the circumstances raise an inference that the protected activity was a contributing factor in the personnel action. 29 C.F.R. § 1980.104(b)(1) (2007).

To satisfy the first element and establish that he engaged in protected activity, an employee must show that he had both “a subjective belief and an objectively reasonable belief’ that the conduct he complained of constituted a violation of relevant law. Livingston, 520 F.3d at 352. Additionally, an employee must show that his communications to his employer “definitively and specifically relate[d]” to one of the laws listed in § 1514A. Platone v. FLYi, Inc., ARB Case No. 04-154, 25 IER Cases 278, 2005 O.S.H.D. (CCH) P 32843, slip op. at 17 (ARB Sept. 29, 2006) (internal quotation marks omitted). The ARB held that Welch failed to make out a prima facie case because he did not establish that he had engaged in protected activity; the ARB did not make any determination as to the other three elements necessary for a prima facie case.

Under the Administrative Procedure Act, 5 U.S.C. § 706(2)(A) (2006)— which governs our review here, see 49 U.S.C. § 42121(b)(4)(A) — we may only dis[*276] turb the ARB’s decision if it was “arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law.” We review questions of law de novo, giving deference to the ARB’s interpretation of § 1514A. See Chevron U.S.A., Inc. v. Natural Res. Def. Council, Inc., 467 U.S. 837, 843-44, 104 S.Ct. 2778, 81 L.Ed.2d 694 (1984). ^[2] On questions of fact, we will uphold the ARB’s findings if supported by substantial evidence. See Knox v. U.S. Dep’t of Labor, 434 F.3d 721, 723-24 (4th Cir.2006).

III.

Before turning to the central dispute here — whether the ARB erred in holding that Welch had failed to establish that his communications constituted protected activity under § 1514A — we briefly address contentions made by the parties as to the standard for establishing protected activity-

Cardinal initially argues that Livingston holds that the Sarbanes-Oxley Act only protects communications relating to material violations of a listed law. As Cardinal itself concedes, however, in Livingston, we merely noted that a statement or omission must concern a material fact to violate § 10(b) of the Securities Exchange Act and SEC Rule 10b-5. 520 F.3d at 355. Although many of the laws listed in § 1514A of the Sarbanes-Oxley Act contain materiality requirements, nothing in § 1514A (nor in Livingston) indicates that § 1514A contains an independent materiality requirement. ^[3]

The parties’ remaining contentions involve the ARB’s interpretation of § 1514A to require that an employee’s communications to his employer “definitively and specifically relate” to one of the listed laws for these communications to constitute protected activity. See, e.g., Platone, ARB Case No. 04-154, slip op. at 17 (internal quotation marks omitted). This requirement ensures that an employee’s communications to his employer are factually specific. An employee need not “cite a code section he believes was violated” in his communications to his employer, but the employee’s communications must identify the specific conduct that the employee believes to be illegal. Fraser v. [*277] Fiduciary Trust Co. Int’l, 417 F.Supp.2d 310, 322 (S.D.N.Y.2006); see also Bechtel Constr. Co. v. Sec’y of Labor, 50 F.3d 926, 931 (11th Cir.1995) (considering standard for protected activity under the whistle-blower provisions of the Energy Reorganization Act, 42 U.S.C. § 5851). “[General inquiries do not constitute protected activity.” Fraser, 417 F.Supp.2d at 322 (internal quotation marks, omissions, and citations omitted).

Welch maintains that by requiring his communications to “definitively and specifically relate” to a listed law, the ARB has interpreted § 1514A to require that an employee complain of an actual violation of a listed law in order to engage in protected activity, and that such a requirement contradicts the text of the statute, which provides that an employee who complains of conduct that he “reasonably believes” violates a listed law engages in protected activity. 18 U.S.C. § 1514A(a)(l). We agree that such a requirement would contradict the text of § 1514A, but the “definitively and specifically” language does not in fact require that an employee complain of an actual violation. Indeed, the ARB has squarely held that § 1514A protects an employee’s communications based on a reasonable, but mistaken, belief that conduct constitutes a securities violation. See Halloum v. Intel Corp., ARB Case No. 04-068, 24 IER Cases 50, slip op. at 6 (ARB Jan. 31, 2006); accord Allen, 514 F.3d at 477.

Cardinal also misreads the “definitively and specifically” language, though in a different manner. Cardinal contends that the “definitively and specifically” language imposes a heightened pleading standard in Sarbanes-Oxley whistleblower cases. The ARB, however, has held that, for the requirement that an employee’s communications “definitively and specifically relate” to a listed law, the “relevant inquiry” is what an employee “actually communicated to [his] employer prior to the ... termination”; it is “not what [is] alleged in [the employee’s] OSHA complaint.” Platone, ARB Case No. 04-154, slip op. at 17 (emphasis added). Thus, contrary to Cardinal’s assertions, the “definitively and specifically” language clearly does not impose a heightened pleading standard in Sarbanes-Oxley whistleblower cases.

Accordingly, we turn to the central issue in this case — whether Welch established that his communications constituted activity protected by § 1514A.

IV.

The ARB held that Welch had failed to establish that any of his communications constituted protected activity under § 1514A of the Sarbanes-Oxley Act. The ARB offered two rationales for its holding; both relate to the requirement that Welch have an objectively reasonable belief that the challenged conduct violated relevant law. Although we must reject the first rationale, we find no error in the second.

A.

The ARB initially held, as a matter of law, that Welch could not have had an objectively reasonable belief that reporting the $195,000 in recovered loans as income violated relevant law. ^[4] The[*278] ARB reasoned that even if Cardinal erroneously reported the $195,000 as income instead of recording it in the loan reserve account, the erroneous entries still showed that “Cardinal had in fact recovered $195,000 that it previously did not have,” and that therefore Welch could not have had an objectively reasonable belief that the loan entries might mislead investors.

The ARB suggested that the misclassifi-cation of items in a financial statement can never “present[ ] potential investors with a misleading picture of [a company’s] financial condition,” so long as the misclassification does not affect the “bottom line.” We disagree. As the SEC has explained in its amicus brief, “ ‘[t]he individual items, subtotals, or other parts of a financial statement may often be more useful than the aggregate to those who make investment, credit, and similar decisions.’ ” Statement of the SEC, Amicus Curiae, in Support of Neither Side at 3 (quoting the Financial Accounting Standards Board, Statement of Financial Accounting Concepts No. 5, Recognition and Measurement of Financial Statements of Business Enterprises 15-16, ¶ 22 (Dec.1984)) (emphasis omitted). Thus, as the Department of Labor now concedes, communications about misclassi-fications in financial statements may, in some circumstances, form the basis for a Sarbanes-Oxley whistleblower action, and the ARB erred to the extent that it held to the contrary. Were this the only rationale for the ARB’s holding, we would have to remand to allow the ARB to determine whether Welch could have reasonably believed that this misclassification violated relevant law.

B.

The ARB offered a second rationale for its dismissal of Welch’s complaint, however. The ARB held that even if Welch’s charges proved correct — that Cardinal reported the $195,000 as income in violation of GAAP, that Cardinal improperly restricted Welch’s access to Larrowe & Co., and that Moore permitted individuals without expertise to make ledger entries— Welch had nonetheless failed to explain to the ARB how he could have had an objectively reasonable belief that these actions violated any of the laws listed in § 1514A.

After the ALJ ruled in favor of Welch, Cardinal filed a petition for review with the ARB, taking exception to the ALJ’s findings of fact and conclusions of law, pursuant to 29 C.F.R. § 1980.110 (2007). Cardinal specifically took issue with the ALJ’s rulings that Welch had an objectively reasonable belief that his communications identified violations of federal securities laws. See Resp’t’s Pet. for Review at ¶¶ 2, 4, 5 (Feb. 25, 2005). Cardinal argued that:

The ALJ erred in finding protected activity because Welch’s complaints ... did not allege conduct that constituted a violation of, or even a reasonably perceived violation of, federal securities laws. Conspicuously absent from the ALJ’s analysis is any explanation of how[*279] the conduct Welch complained about constituted a violation of federal securities laws.

Br. of Resp’t at 11, Welch v. Cardinal Bankshares Corp., ARB Case No. 05-064 (ARB May 31, 2007). Cardinal stressed that the ALJ had cited “no authority” to support the proposition that the identified conduct violated federal securities laws. Id. at 18; see also id. at 16 (asserting that Welch’s communications “did not allege a violation of federal securities law” and that “[t]he ALJ fails to point to a single statute, regulation, or case” in support of his holding).

In his response before the ARB, Welch defended the ALJ’s holding, but, like the ALJ, he utterly failed to explain how Cardinal’s alleged conduct could reasonably be regarded as violating any of the laws listed in § 1514A. Although Welch advanced several arguments before the ARB, he supported these arguments only with irrelevant and inapposite authority or concluso-ry, general statements. ^[5] The ARB therefore held that Welch had failed to establish that he engaged in protected activity. We find no error in this ruling. See, e.g., Hall v. U.S. Dep’t of Labor, Admin. Review Bd., 476 F.3d 847, 861 n. 8 (10th Cir.2007) (explaining that the ARB is not required to “sua sponte raise legal theories referenced only obliquely by a party but not clearly articulated in its briefs”); cf. Fed. R.App. P. 28(b), (a)(9)(A) (requiring the appellee’s brief to contain an argument, which must, in turn, include “citations to the authorities and parts of the record on which [that party] relies”).

To the extent that Welch now explains his position and cites to relevant authority in his filings before this court, he attempts to raise new arguments relying on newly identified authorities. Welch has forfeited these new arguments by failing to raise them before the ARB. See, e.g., Taylor v. U.S. Dep’t of Labor, 440 F.3d 1, 8-9 (1st Cir.2005).

Of course, we do not suggest that a whistleblower must identify specific statutory provisions or regulations when complaining of conduct to an employer, nor do we address the burden upon the parties in the proceedings before the ALJ. See 29 C.F.R. §§ 1980.103-109 (2007). We simply hold that Welch completely failed to raise any relevant arguments before the ARB and may not now raise new arguments before this court.

V.

For the reasons set forth above, the judgment of the Administrative Review Board is

AFFIRMED.
