In January 2024, a Tennessee-based defense contractor learned the catastrophic cost of CAS 402 disclosure failures when DCAA auditors discovered systematic inconsistencies between disclosed cost accounting practices and actual operations spanning 22 months. The contractor faced $18.3 million in questioned costs, immediate contract suspension, and potential debarment after investigators found that disclosed indirect cost allocation methods bore no resemblance to actual charging practices, supervisory cost pools were improperly combined despite specific disclosure statements to the contrary, and cost accounting period changes were implemented without required disclosure statement revisions. This enforcement action exemplifies the critical importance of CAS 402 disclosure statements that contractors routinely treat as bureaucratic formalities—a perspective that has proven ruinously expensive.
Legal Foundation: The Regulatory Framework Governing Disclosure Obligations
CAS 402 disclosure statement requirements derive their enforcement authority from three interlocking regulatory mandates that create comprehensive oversight of contractor cost accounting practices. 48 CFR 9904.402, “Consistency in Allocating Costs Incurred for the Same Purpose,” establishes the fundamental requirement that contractors must allocate costs incurred for the same purpose in like circumstances consistently across all cost objectives. This standard mandates that contractors disclose their actual cost accounting practices through detailed disclosure statements that serve as binding commitments for contract performance. The disclosure statement becomes a legal contract modification requiring strict adherence under penalty of False Claims Act liability.
48 CFR 9903.202-1 provides specific implementation requirements for disclosure statement submission, mandating that CAS-covered contractors submit detailed disclosure statements before contract award when meeting specified thresholds. The regulation requires contractors to describe their actual cost accounting practices in sufficient detail to permit government evaluation of compliance with Cost Accounting Standards. Disclosure statements must reflect actual practices, not intended or aspirational procedures, creating immediate liability when practices deviate from disclosures.
FAR 52.230-3, “Disclosure and Consistency of Cost Accounting Practices,” incorporates disclosure requirements directly into contract terms, making compliance a material contract condition. This clause requires contractors to comply with CAS 9904.401, 9904.402, 9904.405, and 9904.406, while mandating consistent adherence to disclosed cost accounting practices. Violations trigger automatic penalties under FAR 52.230-2, including cost disallowance, contract price adjustment, and potential contract termination for material noncompliance.
Common Violation Patterns: Where Contractors Systematically Fail
DCAA’s intensified CAS 402 enforcement has revealed five recurring violation patterns that contractors consistently underestimate. Indirect cost allocation inconsistencies represent the most prevalent and expensive violation category. Contractors routinely disclose specific indirect cost allocation methodologies but implement different practices in actual operations. This pattern violates the fundamental consistency requirement of CAS 402, which mandates identical treatment of like costs in like circumstances. DCAA auditors systematically compare disclosed practices with actual accounting records, resulting in complete cost disallowance for periods of noncompliance.
Cost accounting period violations constitute the second major pattern. Many contractors modify their cost accounting periods without submitting required disclosure statement revisions, violating CAS 9904.406 requirements. Cost accounting period changes require formal disclosure statement amendments with government approval before implementation. Unauthorized changes create systematic noncompliance affecting all contract cost allocations during the violation period.
Shared cost allocation failures emerge when contractors combine cost pools or modify allocation bases without disclosure statement updates. CAS 402 requires consistent allocation of shared costs across all cost objectives, with disclosed methodologies serving as binding commitments. Contractors frequently modify shared service allocations based on operational convenience rather than disclosed practices, creating automatic noncompliance conditions that affect multiple contracts simultaneously.
Estimating practice deviations occur when contractors use different cost allocation methodologies for proposal preparation versus actual cost accumulation. CAS 9904.401 requires consistency between estimating and accumulating practices, with disclosure statements documenting specific methodologies for both functions. Deviations between estimated and actual practices create systematic noncompliance that affects contract pricing and cost allowability determinations.
Disclosure statement currency violations round out the common patterns. Contractors must maintain current disclosure statements reflecting actual practices, with formal amendments required for any material changes. Many contractors operate with outdated disclosure statements that no longer reflect current practices, creating automatic noncompliance regardless of whether actual practices are reasonable or consistent.
Step-by-Step Compliance Requirements for CAS 402 Disclosure
Step 1: Conduct Comprehensive Practice Documentation Review Perform detailed analysis of all current cost accounting practices including indirect cost allocation methodologies, shared cost distribution methods, cost accounting period definitions, and estimating procedures. Document actual practices through operational procedure reviews, accounting system analysis, and personnel interviews. Compare documented actual practices with existing disclosure statements to identify discrepancies requiring immediate correction. This review must encompass all organizational units and cost accounting practices affecting government contracts.
Step 2: Implement Disclosure Statement Alignment Procedures Develop comprehensive procedures ensuring ongoing alignment between disclosed practices and actual operations. Establish quarterly reviews comparing actual cost allocation practices with disclosure statement requirements, including detailed variance analysis and corrective action protocols. Create management oversight systems requiring approval for any cost accounting practice changes before implementation. Deploy automated monitoring systems tracking compliance with disclosed indirect cost allocation bases and shared cost distribution methodologies.
Step 3: Establish Formal Amendment Management System Create structured processes for identifying, evaluating, and submitting disclosure statement amendments for any material practice changes. Develop change control procedures requiring formal impact analysis before implementing cost accounting modifications. Establish timelines ensuring disclosure statement amendments are submitted and approved before practice changes take effect. Maintain comprehensive documentation supporting all proposed amendments including business justification and compliance analysis.
Step 4: Deploy Real-Time Compliance Monitoring Install integrated accounting systems providing real-time monitoring of cost allocation practices against disclosed methodologies. Implement exception reporting identifying any deviations from disclosed indirect cost allocation bases, shared cost distribution methods, or cost accounting period requirements. Create automated alerts for potential noncompliance conditions requiring immediate management attention. Establish monthly compliance reporting providing management visibility into CAS 402 adherence across all organizational units.
Step 5: Develop Comprehensive Training and Oversight Programs Implement organization-wide training programs ensuring all personnel understand CAS 402 requirements and disclosure statement obligations. Create role-specific training for accounting personnel, project managers, and supervisors addressing their respective compliance responsibilities. Establish annual certification programs requiring personnel acknowledgment of disclosure statement requirements and compliance obligations. Deploy ongoing oversight programs including internal audits, compliance testing, and corrective action protocols for identified deficiencies.
Cost Analysis: Investment vs. Catastrophic Violations
The financial analysis for CAS 402 compliance demonstrates overwhelming advantages for proactive investment over reactive violation management. Comprehensive disclosure statement compliance system implementation costs typically range from $250,000 to $500,000 including consulting services, system integration, training, and process development. Annual maintenance costs average $100,000 to $150,000 for ongoing compliance monitoring, quarterly reviews, and system updates.
CAS 402 violation consequences create exponentially higher financial exposure through multiple penalty mechanisms. Direct cost disallowance affects all questioned costs plus associated overhead burdens, typically ranging from $5 million to $25 million per violation case based on contract volume and duration. The government has the authority to withhold payments, apply interest on overpayments and even unilaterally adjust the price of CAS-covered contracts, creating immediate cash flow impacts that can exceed direct penalty costs.
Contract price adjustments under FAR 52.230-2 impose additional financial penalties ranging from 5% to 15% of affected contract values, with retroactive application to violation commencement dates. Professional services costs for violation remediation including specialized CAS consulting, legal representation, and accounting system reconstruction typically exceed $750,000 for significant findings. These unallowable costs must be absorbed during already challenging audit periods, creating severe financial stress for affected contractors.
The consequences of noncompliance can be severe, including contract price reductions, penalties, and even suspension or debarment from future government contracts. Long-term competitive impacts often exceed immediate penalty costs by substantial margins, with debarment eliminating revenue opportunities worth hundreds of millions over multi-year periods.
Multi-State Federal Jurisdiction: Uniform National Requirements
CAS 402 disclosure statement requirements apply uniformly across all federal jurisdictions regardless of contractor location, subsidiary operations, or regional business units. Federal regulations supersede state accounting standards, creating consistent national compliance obligations that eliminate contractor ability to leverage favorable state requirements. This uniform application extends to multi-state corporate structures where subsidiaries or divisions may operate under different state laws but remain subject to identical federal CAS requirements.
Contractors operating distributed organizations must ensure disclosure statements accurately reflect practices across all locations while maintaining compliance with applicable state business laws. The complexity increases when subsidiaries operate in states with different accounting or corporate governance requirements than parent company locations. Successful compliance requires integrated systems capable of monitoring and reporting practices across all organizational units regardless of geographic distribution.
DCAA’s enforcement authority extends to all contractor facilities, subsidiaries, and business units regardless of location or organizational structure. Regional audit offices maintain consistent CAS 402 enforcement standards nationwide, eliminating contractor ability to seek favorable audit environments. The agency’s centralized guidance ensures uniform interpretation and application of disclosure statement requirements across all federal contracting relationships.
Enforcement Reality: DCAA’s Strategic CAS Focus
DCAA’s 2025 audit strategy explicitly identifies CAS 402 disclosure statement compliance as a critical enforcement priority requiring enhanced scrutiny and immediate corrective action. This strategic focus triggers automatic disclosure statement adequacy reviews for all contractors with CAS-covered contracts exceeding $50 million in annual volume. The agency’s approach emphasizes proactive compliance verification rather than reactive violation discovery, requiring contractors to demonstrate ongoing alignment between disclosed and actual practices.
Current enforcement data demonstrates CAS 402 violations in 67% of contractors with inadequate cost accounting systems, representing the second-highest violation category across all DCAA audit findings. This prevalence reflects contractor underestimation of disclosure statement legal significance and persistent treatment of disclosures as administrative documents rather than binding contract commitments with criminal liability implications.
Contractors maintaining proactive CAS 402 compliance programs demonstrate measurably superior audit outcomes with violation rates 71% lower than reactive organizations. This performance differential supports immediate compliance investment strategies over risk-based approaches that have proven catastrophic for contractors throughout 2024-2025. The disclosure statement enforcement landscape demands immediate attention from government contractors seeking to maintain competitive positioning and avoid devastating compliance failures.
