Securities accounting and GAAP expert
Expert class library · Securities · Either side
Evaluates whether reported financial statements complied with GAAP and whether a restatement reflects an error that was knowable at the time. Often addresses scienter indicators such as red flags and weak internal controls.
What this expert is retained to answer
- Did the company's revenue recognition or asset valuation comply with GAAP when the statements were issued?
- Were management's assumptions, estimates, and forecasts reasonable under the applicable accounting standards?
- Was the misstatement material to the company's financial position?
- Did the auditor's work comply with the applicable auditing standards?
Methods
- GAAP compliance review
- Restatement analysis
- Revenue recognition testing
- Internal controls assessment
How the testimony is attacked
- Opinions on the defendants' state of mind. Accounting experts may explain whether the books complied with GAAP but not what executives knew or intended. In REMEC the court struck the parts of the plaintiffs' accountant's report that opined on the defendants' mental state.
- Substituting the expert's judgment for management's. Defendants argue the expert simply swapped in different assumptions for areas such as goodwill impairment that call for professional judgment. The REMEC court rejected that attack where the rebuttal accountant explained why each alternative input was more appropriate.
- Expertise in the wrong accounting or auditing regime. An expert trained in foreign standards may be unable to speak to US GAAP or PCAOB requirements. In Puda Coal the court excluded the plaintiffs' only auditing expert because her Hong Kong and PRC expertise was irrelevant to whether the audits met the governing standards.
- Improper factual findings dressed as accounting opinion. Opponents contend the expert resolved disputed facts, such as whether a side agreement existed, before applying GAAP. Courts generally allow the expert to assume facts but leave the factual dispute for the jury.
- Unhelpful testimony on matters jurors understand. Defendants sometimes argue that revenue recognition is common sense. In SEC v. Johnson the court held that applying GAAP concepts like delivery, collectibility, and fixed price is beyond the average juror and admitted the SEC's accounting expert.
What the public record shows
A deliberately narrow CourtListener search, GAAP AND restatement AND "expert testimony" AND (Daubert OR "Rule 702"), returned 5 opinions filed since 2015, as of October 2, 2026; broader searches return more. Three that show how courts handle this class of testimony:
| Outcome | Case | Court | Why |
|---|---|---|---|
| Limited | In re REMEC Inc. Securities Litigation702 F. Supp. 2d 1202 | S.D. Cal. 2010 | The court refused to strike the plaintiffs' rebuttal accountant's goodwill impairment analysis but granted in part the motion against the other accounting expert because he went beyond accounting to opine on the defendants' mental state. |
| Excluded | In re Puda Coal Securities Inc., Litigation30 F. Supp. 3d 230 | S.D.N.Y. 2014 | The court excluded the plaintiffs' sole auditing expert because her expertise in Hong Kong and PRC standards did not bear on the audit issues in the case, then granted the auditors summary judgment. |
| Admitted | Securities & Exchange Comm'n v. Johnson525 F. Supp. 2d 70 | D.D.C. 2007 | The court allowed the SEC's accounting expert to explain revenue recognition and opine that booking a disputed amount violated GAAP, holding that reliance on GAAP and auditing standards is a valid non-scientific methodology under Kumho. |

Under amended Rule 702
Since December 1, 2023, Rule 702 says expressly that the party offering an expert must show the court it is more likely than not that the testimony meets each requirement: that it rests on sufficient facts or data, uses reliable methods, and reflects a reliable application of those methods to the case. Questions about the basis of an opinion are no longer automatically matters of weight for the jury. For how the circuits have applied the amendment, see the Rule 702 tracker, which follows each court of appeals; for what that means for preparing or attacking this class of expert, see the guide on amended Rule 702.

Last reviewed October 2, 2026. How this page is built: rulings are found by searching court opinions on CourtListener, and each one is read in the opinion before it is summarised here; outcomes are labelled by what the court did with the expert's testimony. No individual expert is named. This page summarises public decisions for orientation and is not legal advice; read the opinion before relying on any ruling.
