Opening Scenario: A Hypothetical Mid‑Size Bank Faces a Merger Deadline

Imagine a mid‑size regional bank, Riverbend Bank, that has just completed a $3 billion acquisition of a neighboring community bank. The deal closed on August 1, 2024, and the integration team is racing to combine core banking systems, consolidate customer data, and harmonize risk‑management frameworks. Riverbend’s Chief Data Officer (CDO) knows that the Office of the Comptroller of the Currency (OCC) has just issued an interim final rule that reshapes the OCC merger recertification landscape for banks that undergo mergers or major reorganizations.

The rule, published on July 15, 2024 (OCC 2024‑40), requires every OCC‑regulated institution to submit a comprehensive recertification plan within 90 days of a merger, demonstrating that its data‑governance program meets the updated standards for ownership, accountability, and auditability. Riverbend’s leadership must decide whether to treat the new requirement as a routine compliance checkbox or as a strategic opportunity to strengthen its data‑risk posture.

The thesis of this article is clear: the OCC’s merger recertification rule fundamentally changes how banks plan, execute, and document post‑deal data‑governance, and a disciplined, technology‑enabled approach is essential to avoid costly delays and supervisory findings. This article will walk through the practical challenges, the regulatory specifics, and how a platform like CoComply can turn a mandated deadline into a competitive advantage.

Problem: Legacy Governance Gaps Exposed by the New Recertification Rule

The OCC’s interim final rule, formally titled Interim Final Rule on Recertification After Mergers and Reorganizations (OCC 2024‑40), was issued to address a pattern of supervisory findings where banks failed to re‑evaluate data‑ownership structures after a merger. The rule mandates that banks:

  1. Identify every data asset that changes ownership or control as a result of the transaction. 2. Update data‑classification schemas to reflect new regulatory obligations, including the Consumer Financial Protection Bureau’s Data Rights Rule and the Federal Financial Institutions Examination Council’s (FFIEC) data‑risk guidance. 3. Document a revised data‑governance framework that includes updated roles, responsibilities, and reporting lines for data stewards, custodians, and owners. 4. Conduct a risk‑based audit of the merged data environment within 180 days, producing an OCC‑acceptable audit trail that demonstrates compliance with the revised framework. 5.

Submit a formal recertification package to the OCC, including a data‑flow diagram, a control‑testing summary, and a remediation plan for any identified gaps.

For many banks, the rule surfaces three interrelated challenges. First, legacy data‑governance programs are often siloed, with separate stewardship models for each legacy institution. When those silos are merged, ownership ambiguities arise, leading to duplicate or conflicting data‑classification decisions. Second, the rule’s 90‑day submission deadline collides with the typical post‑merger integration timeline, which can stretch six months or longer, especially when core‑system migrations are involved. Finally, the requirement for a detailed audit trail forces banks to adopt more granular monitoring and logging capabilities, capabilities that many legacy platforms lack.

The consequences of non‑compliance are severe. The OCC has signaled that failure to submit a satisfactory recertification package can trigger supervisory enforcement actions, including civil money penalties and, in extreme cases, restrictions on the bank’s ability to complete the merger. Moreover, gaps in data‑ownership documentation can expose banks to downstream regulatory risks under the CFPB’s Data Rights Rule, the SEC’s climate‑disclosure requirements, and state‑level data‑privacy statutes such as the California Consumer Privacy Act (CCPA).

To illustrate, consider a scenario where a bank overlooks a critical data set transferred from the acquired institution. That omission could lead to a finding that the bank failed to identify all data assets, prompting the OCC to demand a supplemental submission and potentially imposing a penalty that erodes the financial benefits of the merger. The rule therefore transforms a peripheral data‑governance exercise into a core compliance milestone that directly impacts a bank’s merger timeline and overall risk profile.

The CoComply Approach

CoComply’s platform is built to help banks meet the OCC merger recertification obligations without adding manual overhead. Our solution automates the identification, classification, and documentation of data‑ownership changes across merged entities. By ingesting data‑lineage information from source‑system catalogs, cloud‑storage inventories, and third‑party data‑warehouses, CoComply generates a unified data‑asset register that maps each asset to its new owner, steward, and regulatory classification. The platform then produces the required OCC‑style data‑flow diagrams and control‑testing reports, complete with audit‑ready logs that satisfy the 180‑day audit‑trail requirement.

Key capabilities that align with the OCC rule include:

  • Automated Ownership Mapping – CoComply’s AI‑driven engine reconciles overlapping data‑ownership definitions from the legacy banks, surfacing conflicts and recommending a consolidated stewardship hierarchy. * Regulatory Classification Engine – Leveraging the latest CFPB, FFIEC, and state‑level guidance, the platform tags each data asset with the appropriate regulatory label, ensuring that the merged data set complies with all applicable rules. * Risk‑Based Audit Trail Generation – Every change to data‑ownership or classification is logged in an immutable ledger, providing the granular evidence the OCC expects in the recertification package.
  • Pre‑Built Recertification Package Templates – CoComply delivers a fully populated OCC‑compliant submission package, including narrative explanations, data‑flow diagrams, and remediation roadmaps, ready for review by the bank’s compliance team.

Beyond the core features, CoComply offers integration hooks that embed directly into post‑merger project management tools, allowing data‑governance tasks to be tracked alongside system‑migration milestones. This ensures that the 90‑day deadline is visible to integration managers and that any delays are flagged early. Moreover, the platform’s reporting dashboard provides a real‑time view of outstanding data‑ownership gaps, enabling banks to prioritize remediation efforts that have the greatest supervisory impact.

By embedding these capabilities into the post‑merger integration workflow, banks can meet the 90‑day OCC merger recertification deadline while simultaneously strengthening their overall data‑risk posture. The result is a smoother integration, reduced supervisory risk, and a clear, auditable path to regulatory compliance.

Closing: Turning Recertification Into a Competitive Advantage

The OCC’s merger recertification rule is more than a compliance checkbox; it is a catalyst for banks to modernize their data‑governance foundations at a critical moment of change. Institutions that treat the rule as a strategic lever, automating ownership mapping, aligning classifications with the latest regulatory landscape, and building an audit‑ready trail, will not only avoid enforcement risk but also gain a clearer view of their data assets, enabling faster product innovation and more resilient risk management.

For banks like the hypothetical Riverbend Bank, partnering with CoComply turns a regulatory deadline into a roadmap for data‑driven growth, ensuring that the merged entity emerges stronger, more transparent, and fully prepared for the next wave of supervisory expectations. In the long run, the discipline imposed by the OCC’s merger recertification rule can become a source of competitive differentiation, allowing banks to leverage high‑quality data governance as a platform for new services, improved customer trust, and sustainable profitability.
