Financial Investigations and Regulatory Enforcement

Independent investigations, remediation, regulatory response, and litigation support for corporations and their counsel delivered by a multidisciplinary team with deep forensic, industry, and data-driven experience.

Investigation, Enforcement, and Litigation Support Across the Full Matter Lifecycle

Government investigations, regulatory enforcement, and complex litigation matters require more than fact-gathering and financial analysis. Boards, audit committees, corporate executives, and their legal counsel are under pressure to show that potential violations have been investigated thoroughly, that impact has been quantified, root causes have been identified, and that remediation is effective. Citrin Cooperman's Financial Investigations and Regulatory Enforcement team is built for this standard.

We frequently operate under the direction of legal counsel to support privilege and work product protections with a clear understanding of discovery expectations and evidentiary standards. Our team of experienced professionals combines former industry risk and compliance professionals, forensic accountants, data scientists, and testifying experts in a single, integrated workstream so findings are both factually defensible and operationally actionable.

We assist clients and legal counsel through every stage of the investigative and enforcement lifecycle from early risk assessments and internal investigations to government inquiries, litigation support, damage analysis, remediation, and expert testimony. Our analyses are designed to withstand regulatory scrutiny, expert challenge, and cross examination.

Whether the matter involves an internal investigation, a qui tam whistleblower lawsuit, or a regulatory inquiry, we help our clients tell a credible story supported by facts, grounded in evidence, anchored in the data, and tailored to the regulator or plaintiff on the other side of the table.

Forensic Accounting and Advisory Across Every Stage of the Matter

Each engagement is scoped to the matter. Our team's work typically spans the following areas:

Internal Investigations

Organizations facing allegations of misconduct require a structured investigative process to determine what occurred, when and how it occurred, who was involved, and the extent of impact. Our professionals conduct forensic accounting investigations on behalf of management teams, boards of directors, audit committees, and internal and outside counsel. Investigations are scoped and documented in anticipation matters may involve self reporting to regulators or create litigation exposure.

We investigate a broad range of complex matters including:

  • Financial reporting irregularities and accounting manipulation
  • Employee misconduct and misappropriation of assets
  • Whistleblower allegations and internal complaint investigations
  • Vendor and procurement fraud
  • Consumer and investor harm matters
  • Financial crimes including anti-money laundering and FCPA
  • Alleged trade fraud and tariff evasion

Where appropriate, we work with organizations and their legal counsel to develop the facts necessary to assess voluntary self-reporting obligations and to develop remediation plans designed to prevent recurrence.

Regulatory Investigations

Credibility is critical in regulatory investigations. Companies subject to government inquiries require structured, independent analysis and well-supported responses. We assist with document analysis, financial reconstruction, data analysis, and the development of defensible investigative findings. Our professionals have appeared before regulatory staff on behalf of clients to explain investigation findings and remediation measures undertaken. We work with legal counsel in responding to regulators across broker-dealer, consumer banking, investment adviser, and importer matters. We provide practical guidance on the key factors that regulators consider including self-policing, self-reporting, remediation, and cooperation and help clients build a credible, well-documented record across each dimension.

Litigation and Disputes Support

Forensic accounting and data analysis play a critical role in complex commercial litigation and government enforcement disputes. Early case assessment, class certification, damages quantification, financial analysis, and expert opinions require professionals with experience in both the accounting and legal frameworks governing these matters.

We assist law firms and corporate clients with:

  • False Claims Act matters including qui tam defense and damages analysis
  • Class action litigation defense
  • White collar criminal tax defense
  • Valuation disputes and post-acquisition claims
  • Economic damages analysis and quantification
  • Regulatory enforcement litigation

Our professionals may serve as consulting experts, testifying experts, neutral accounting arbiters, or in support of expert witness teams in litigation and arbitration matters. We have also served as court-appointed fiduciaries and receivers.

Customized Data Analytics and Investigative Technology

Complex forensic accounting investigations frequently require analyzing large volumes of structured and unstructured financial data across multiple systems, time periods, and formats. Our team applies advanced data analytics and investigative technology to identify anomalies, reconstruct financial transactions, and assess financial exposure at scale.

Our methodology covers four phases:

  1. Planning: Define objectives, identify datasets, scope availability and retention issues
  2. Preservation and Collection: Secure collection across structured and unstructured sources, chain of custody documentation
  3. Integration and Quality Control: Normalize and cleanse data, document limitations
  4. Analysis and Reporting: Time series analysis, outlier detection, financial modeling, data visualization, and custom analytics aligned to engagement objectives

Remediation and Financial Restitution

Following an investigation or enforcement matter, organizations need to address root causes, remediate harm where applicable, and strengthen compliance programs to reduce future risk.

Our professionals assist clients with:

  • Root cause analysis and control gap identification
  • Internal controls assessment and remediation roadmap development
  • Customer harm remediation including eligibility criteria and restitution calculations
  • Compliance program risk assessments covering anti-fraud, anti-bribery, trade monitoring and surveillance
  • Whistleblower programs
  • Monitoring and governance framework improvements

Trade, Tariff, and Customs Investigations

International trade compliance has become a significant area of civil and criminal enforcement risk. In an environment of shifting U.S. trade policies, expanding use of the False Claims Act, and heightened scrutiny from the DOJ and CBP, importers face meaningful exposure to tariff-related investigations and disputes.

Working closely with importers and their legal counsel, our professionals apply investigative techniques and advanced data analytics to gather evidence, quantify exposure, and develop remediation plans.

Key areas include:

  • Tariff classification and customs valuation analysis
  • Country of origin reviews and supply chain tracing
  • False Claims Act exposure analysis related to customs filings, financial reconstruction and damages quantification
  • Voluntary self-disclosure support
  • Enforcement inquiry and regulatory response support including DOJ and CBP matters

Frequently Asked Questions

What is forensic accounting?

Forensic accounting applies accounting, auditing, and investigative skills to matters that may involve litigation, regulatory inquiry, or enforcement action. Forensic accountants reconstruct financial transactions, identify irregularities, quantify damages, and produce findings that can withstand scrutiny in legal and regulatory proceedings.

What does the Financial Investigations and Regulatory Enforcement team handle?

The Financial Investigations and Regulatory Enforcement team handles internal investigations, regulatory enforcement response, litigation and disputes support, data analytics for complex financial matters, trade and tariff investigations, and post-investigation remediation. Engagements are scoped to the specific matter and frequently operate under the direction of outside counsel.

When should I engage a forensic accounting team?

Organizations should consider engaging a forensic accounting team when facing allegations of misconduct, whistleblower complaints, government inquiries, regulatory examinations, or complex litigation involving financial damages. Earlier engagement typically preserves more options and protects the integrity of the evidentiary record.

What is a qui tam lawsuit?

A qui tam lawsuit is a type of False Claims Act action in which a private party, known as a relator, files suit on behalf of the government alleging fraud against a federal program. If the government intervenes or the relator prevails, a portion of any recovery goes to the relator. Organizations named in qui tam actions require independent forensic accounting analysis to assess exposure and develop a credible defense.

How does the Financial Investigations and Regulatory Enforcement team work with outside counsel?

The Financial Investigations and Regulatory Enforcement team frequently operates under the direction of outside counsel to support attorney-client privilege and work product protections. We understand discovery expectations and evidentiary standards, and we structure our work to produce findings that are both factually defensible and legally usable.

How do I choose a forensic accounting firm?

The right forensic accounting firm for a matter should have direct experience with the regulatory agencies or litigation context involved, a multidisciplinary team combining forensic accountants, data scientists, and industry specialists, and a track record of producing findings that hold up under regulatory scrutiny and cross examination. Independence and privilege-awareness are also critical, particularly for matters that may involve self-reporting or parallel civil and criminal proceedings.

What is the False Claims Act?

The False Claims Act is a federal statute that imposes civil liability on entities that submit false claims to the federal government. It covers a wide range of conduct including healthcare billing fraud, customs and trade fraud, and defense contractor fraud. The False Claims Act also authorizes qui tam whistleblower lawsuits by private parties acting on the government's behalf.

What types of data does the Financial Investigations and Regulatory Enforcement team analyze?

The Financial Investigations and Regulatory Enforcement team analyzes accounting and financial records, electronic communications, securities trading data, customs filing data, systems access logs, and other structured and unstructured data sources. Advanced analytics capabilities include time series analysis, outlier detection, financial modeling, and data visualization tailored to the specific engagement.
