Litigation, Claims, and Assessments

Litigation, claims, and assessments represent some of the most challenging areas in an audit because they involve future outcomes that are inherently uncertain. A pending lawsuit may result in a massive liability—or it may be dismissed entirely. Auditors must design procedures that identify these matters, evaluate their financial statement impact, and determine whether management has properly accounted for and disclosed them. This topic is tested on the CPA exam under AUD blueprint area III.E.4 and draws heavily on AU-C 501 (AICPA) and AS 2505 (PCAOB).

Audit Procedures to Detect Litigation, Claims, and Assessments

Because management may not voluntarily disclose unfavorable legal matters, the auditor cannot rely solely on management inquiry. A combination of procedures is needed to identify pending or threatened litigation:

1. Inquire of Management

The auditor should ask management—including in-house legal counsel—about:

• Pending or threatened litigation, claims, and assessments
• Unasserted claims that the client's lawyers have advised are probable of assertion
• The entity's policies and procedures for identifying, evaluating, and accounting for litigation
• Whether any litigation has arisen since the balance sheet date

tip

Frame inquiries broadly. Ask about disputes with customers, employees, regulators, and competitors—not just "lawsuits." Management may not classify a regulatory investigation or tax dispute as "litigation" unless prompted.

2. Review Minutes of Board and Committee Meetings

Board of directors and audit committee minutes frequently reference:

• Reports from in-house or outside counsel on pending legal matters
• Authorizations for settlement negotiations
• Discussions of regulatory inquiries or government investigations
• Insurance coverage decisions related to litigation risk

3. Read Legal Invoices and Correspondence

Reviewing legal invoices and correspondence can reveal matters that management has not disclosed:

Document	What It May Reveal
Legal invoices	Engagement of outside counsel for specific matters (e.g., employment disputes, patent litigation)
Demand letters received	Threatened claims from third parties
Correspondence with regulators	Pending investigations, consent decrees, or enforcement actions
Insurance claim filings	Claims filed under directors & officers (D&O) or general liability policies
Settlement agreements	Resolved matters that may require disclosure or remaining payment obligations

4. Other Detection Procedures

• Review contracts for indemnification clauses, guarantees, and penalty provisions
• Examine tax correspondence for disputed assessments from the IRS or state tax authorities
• Read financial press and SEC filings for publicly known legal proceedings
• Review bank confirmations for information about contingent liabilities

No single procedure is sufficient by itself. The auditor combines all of these techniques to build a complete picture of the entity's litigation exposure.

Letters of Inquiry to the Client's Legal Counsel

The attorney letter (also called the audit inquiry letter or legal confirmation letter) is the most important procedure for evaluating litigation, claims, and assessments. It is required under AU-C 501 (AICPA) and AS 2505 (PCAOB).

How the Process Works

1. Management prepares a list of all pending or threatened litigation, claims, and assessments, including:
   • A description of each matter and its current status
   • Management's evaluation of the likelihood of an unfavorable outcome
   • An estimate of the potential loss or range of loss (or a statement that an estimate cannot be made)
2. Management sends the letter to the entity's outside legal counsel, requesting the attorney to confirm or supplement management's descriptions
3. The attorney responds directly to the auditor—not back to management

note

The letter is prepared and sent by management, not by the auditor. This is because the attorney-client relationship belongs to the client. However, the attorney's response is addressed directly to the auditor to preserve the independence and reliability of the evidence.

Content of the Inquiry Letter

The inquiry letter typically requests the attorney to provide information on:

Item	Description
Pending litigation	Description, progress, and planned action for each matter identified by management
Unasserted claims	Matters that the attorney has advised the client are probable of being asserted and, if asserted, would have a reasonable possibility of an unfavorable outcome
Attorney's evaluation	The attorney's view on the likelihood of an unfavorable outcome and an estimate (or range) of potential loss
Omissions	Whether management's list is complete or whether additional matters should be disclosed
Billing period	Typically covers the period from the balance sheet date through a date near the audit report date

Evaluating the Attorney's Response

The attorney categorizes the likelihood of an unfavorable outcome using the standard contingency terminology from ASC 450-20:

Likelihood Category	Definition	Financial Statement Treatment
Probable	The future event is likely to occur	Accrue the loss if the amount is reasonably estimable; disclose in the notes
Reasonably possible	The chance is more than remote but less than likely	Disclose in the notes (no accrual required)
Remote	The chance is slight	Generally no disclosure required (except for certain guarantees)

warning

If the attorney states that a loss is "probable" but cannot provide a reasonable estimate, the entity must still disclose the contingency in the notes—even though no accrual is recorded. The auditor should evaluate whether the disclosure is adequate.

Limitations on Attorney Responses

Attorneys may limit their responses due to attorney-client privilege and ethical obligations:

• An attorney may decline to respond regarding matters where the attorney was not directly involved
• An attorney may use qualifying language (e.g., "we are unable to express an opinion") for highly uncertain matters
• An attorney may limit the response to specified dollar thresholds (e.g., matters involving potential losses exceeding $100,000)
• An attorney is generally not required to disclose unasserted claims unless the client has specifically authorized the disclosure

caution

A refusal by the attorney to respond—or a significantly limited response—does not automatically mean the attorney is hiding something. However, the auditor must evaluate whether sufficient appropriate evidence has been obtained. A material limitation may constitute a scope limitation affecting the audit opinion.

Example: Attorney Letter at Kingfisher Industries

Kingfisher Industries is defending against two lawsuits:

1. Patent infringement claim filed by a competitor seeking $2,000,000 in damages
2. Slip-and-fall personal injury claim by a former employee seeking $150,000

Management prepares a letter listing both matters and sends it to Kingfisher's outside counsel. The attorney responds:

• Patent claim: Likelihood of unfavorable outcome assessed as "reasonably possible"; potential loss range of $500,000–$2,000,000
• Personal injury claim: Likelihood assessed as "probable"; estimated loss of $120,000

Based on the response, the auditor verifies that Kingfisher has:

• Accrued $120,000 for the personal injury claim (probable and estimable)
• Disclosed the patent infringement claim in the notes with the range of potential loss (reasonably possible)

Financial Statement Implications

Loss Contingency Recognition Under ASC 450

The accounting treatment for litigation-related contingencies follows ASC 450-20 (Contingencies—Loss Contingencies):

Condition	Accrual Required?	Disclosure Required?
Loss is probable AND reasonably estimable	✅ Yes—record a liability	✅ Yes—disclose in the notes
Loss is probable but not estimable	❌ No accrual	✅ Yes—disclose the nature and indicate that an estimate cannot be made
Loss is reasonably possible	❌ No accrual	✅ Yes—disclose the nature and estimated range of loss (or state that an estimate cannot be made)
Loss is remote	❌ No accrual	❌ Generally no (except for certain guarantees under ASC 460)

Accrual Best Practices

When a range of loss is estimated and no amount within the range is a better estimate than any other, the entity should accrue the minimum amount in the range and disclose the full range. This is a frequently tested CPA exam concept.

Example: Loss Contingency at Bear Co.

Bear Co. is the defendant in a class-action product liability lawsuit. Management and legal counsel evaluate the matter:

• Likelihood of unfavorable outcome: Probable
• Estimated range of loss: $3,000,000 to $8,000,000
• No single amount within the range is more likely than another

Bear Co. should:

1. Accrue $3,000,000 (the minimum of the range)
2. Disclose the nature of the lawsuit and the full $3,000,000–$8,000,000 range in the notes

The auditor verifies this treatment is consistent with ASC 450-20 and AU-C 501.

Management Representations

As part of the management representation letter (AU-C 580), the auditor obtains written representations from management specifically addressing:

• All known pending or threatened litigation has been disclosed to the auditor
• All unasserted claims that legal counsel has advised are probable of assertion have been disclosed
• Financial statement accruals and disclosures related to litigation are complete and adequate
• Management has disclosed any litigation arising after the balance sheet date through the date of the auditor's report

tip

The management representation letter supplements—but does not replace—the attorney letter. Both are required. The representation letter confirms management's responsibility for completeness; the attorney letter provides corroborating evidence from an independent legal professional.

Example: Representation Letter at Illini Entertainment

Illini Entertainment's CFO signs a management representation letter stating: "We have disclosed to you all pending and threatened litigation and claims. We believe the accruals and disclosures in the financial statements are adequate." However, during the subsequent events review, the auditor discovers a new $5,000,000 copyright infringement lawsuit filed two weeks after the balance sheet date. The auditor must:

1. Inquire about why this was not disclosed earlier
2. Evaluate whether the lawsuit relates to conditions existing at the balance sheet date
3. Determine whether an accrual or disclosure adjustment is needed
4. Consider the implications for management integrity and the reliability of representations

Impact on the Auditor's Report

Scope Limitations Related to Litigation

Scenario	Impact on Audit Report
Client refuses to send the attorney letter	Scope limitation—qualified opinion or disclaimer of opinion
Attorney refuses to respond on material matters	Scope limitation—qualified opinion or disclaimer of opinion
Attorney limits response to a dollar threshold, but no material matters are excluded	Not a scope limitation if the auditor is satisfied no material matters were omitted
Attorney cannot estimate the loss for a probable matter	Not a scope limitation—evaluate disclosure adequacy

Emphasis-of-Matter Paragraphs

When litigation creates significant uncertainty about the entity's ability to continue as a going concern or involves a material contingency, the auditor may add an emphasis-of-matter paragraph to the audit report to draw attention to the related disclosure—without modifying the opinion itself.

Example: Audit Report Impact at MAS Inc.

MAS Inc. faces a $50,000,000 government fraud investigation. The company's outside counsel refuses to respond to the auditor's inquiry letter regarding this matter. The auditor:

• Cannot obtain sufficient appropriate evidence about the potential liability
• Determines the matter is both material and pervasive to the financial statements
• Issues a disclaimer of opinion, citing the inability to obtain evidence about the litigation contingency

PCAOB vs. AICPA Considerations

Topic	AICPA (AU-C 501)	PCAOB (AS 2505 / AS 2503)
Applicable entities	Nonissuers (private companies)	Issuers (SEC-reporting companies)
Attorney letter requirement	Required for all audits	Required for all audits
Unasserted claims	Attorney should inform auditor of matters where assertion is probable and loss is reasonably possible	Same requirement
Management representations	Required under AU-C 580	Required under AS 2805
Going concern evaluation	AU-C 570—auditor evaluates whether litigation raises substantial doubt	AS 2415—similar requirement for issuers
Emphasis-of-matter	Permitted for significant uncertainties (AU-C 706)	Explanatory paragraph added after the opinion paragraph (AS 3101)
Internal control over financial reporting	Not required for nonissuers	Auditor must evaluate controls over litigation accrual and disclosure in an integrated audit

PCAOB Integrated Audits

For public companies, the auditor performs an integrated audit of financial statements and internal control over financial reporting (ICFR). This means the auditor must also evaluate whether the entity has effective controls over the identification, evaluation, and disclosure of litigation, claims, and assessments—not just whether the amounts in the financial statements are correct.

Example: PCAOB Integrated Audit at Gies Co.

Gies Co. is a publicly traded manufacturer subject to PCAOB standards. The auditor:

1. Tests controls over the litigation tracking process—evaluating whether management has a system to identify and monitor all legal matters
2. Sends the attorney letter and evaluates the response
3. Tests the accuracy of accruals for probable losses
4. Evaluates the completeness and adequacy of disclosures in the notes
5. Assesses whether any deficiency in the litigation-related controls rises to the level of a significant deficiency or material weakness in ICFR

Summary

AU-C 501 / AS 2505	Requires the auditor to obtain corroborating evidence from the client's legal counsel
Likelihood categories	Probable (accrue if estimable), reasonably possible (disclose), remote (generally no action)
ASC 450-20 accrual rule	Accrue minimum of the range when no single amount is the best estimate
Unasserted claims	Attorney discloses if assertion is probable and loss would be reasonably possible
Management representations	Must specifically address completeness of litigation disclosures
Scope limitation	Client or attorney refusal to cooperate → qualified opinion or disclaimer
