How is an ACL review different from CECL implementation?

Implementation builds or configures the model; an ACL review independently tests the model and calculation management already runs. Institutions typically engage implementation support once, then periodic independent reviews on an ongoing basis.

We use a vendor CECL platform. What does your review cover?

The review covers the institution’s use of the platform: pool segmentation, assumptions, inputs, reconciliation to the GL, qualitative factors, and documentation. Examiners expect institutions to defend vendor model assumptions, not simply rely on the vendor.

How often should the ACL be independently reviewed?

Annual independent review is standard practice, aligned to the examination and external audit cycle. Methodology changes warrant contemporaneous review.

Does the review satisfy model validation expectations?

The review addresses the core elements of model risk management guidance for the ACL: conceptual soundness, computation accuracy, and outcomes analysis, scoped to institution size and complexity.

Independent CECL Methodology and ACL Review

CRF Advisors performs an independent review of the Allowance for Credit Losses (ACL) calculation and the Current Expected Credit Loss (CECL) methodology implemented by management. Our review procedures focus on the completeness of the ACL computation and its supporting documentation, and on conformity of the CECL methodology with the Interagency Policy Statement on the Allowance for Credit Losses and applicable accounting standards.

Background: ASC 326 and the Move to Expected Losses

In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-13 (Topic 326), Financial Instruments — Credit Losses. ASU 2016-13 replaces the incurred-loss impairment methodology in prior GAAP with a CECL methodology and requires consideration of a broader range of information to determine credit loss estimates. Financial assets measured at amortized cost are presented at the net amount expected to be collected through an allowance for credit losses.

In March 2022, the FASB further amended Topic 326 with ASU 2022-02, Financial Instruments — Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures, eliminating TDR accounting for CECL adopters and introducing new loan modification and vintage disclosure requirements. An independent ACL review confirms that the institution’s methodology and disclosures have kept pace with these amendments.

Why an Independent ACL Review Matters

The ACL is one of the largest and most judgment-dependent estimates in a financial institution’s financial statements, and it is a standing focus area for external auditors and federal examiners. An independent review by professionals with no stake in the original methodology gives the board, the audit committee, and examiners confidence that the calculation is complete, accurate, and supportable.

Independent review findings support:

Board and audit committee oversight of the allowance process
Model risk management expectations for independent validation
External audit fieldwork and year-end reporting
Examination readiness and response to prior findings

Summary of Review Procedures

Each ACL review engagement typically includes the following procedures:

Policy and Methodology Compliance Review. Review of the ACL calculation and CECL methodology for compliance with the Interagency Policy Statement on the Allowance for Credit Losses and FASB ASU 2016-13 (Topic 326).
ACL Computation Accuracy Testing. Independent testing of the accuracy of the ACL computation, including formulas, inputs, and roll-forward of prior-period balances.
CECL Reconciliation and GL Verification. Testing of the CECL reconciliation and verification of loan pool balances to the general ledger.
Pool Segmentation Review. Review of pool segmentation and the criteria supporting each pool, confirming segments capture meaningfully distinct risk characteristics.
Life-of-Loan Determination Review. Review of the life determination of loan pools, including prepayment and curtailment assumptions.
Loss Model Recalculation. Recalculation of a sample of PD x LGD or discounted cash flow (DCF) outputs used in the loss model.
Qualitative Assumption Review. Review of qualitative factor assumptions and supporting documentation for directional consistency and supportability.

How We Work

Independence from the methodology under review. We review calculations we did not build; institutions that engaged us for implementation receive review from separately assigned professionals.
Recalculation, not just inspection. Sampled loss model outputs are independently recalculated, not merely traced to documentation.
Findings graded by severity. With practical remediation paths management can act on before the next examination.
Documentation built for examination. Workpapers and conclusions organized for auditor and examiner reliance.

Why Institutions Choose CRF Advisors

Independence by design. Every engagement is structured to preserve the independence that gives our findings credibility with regulators, auditors, and boards. We decline engagements where independence cannot be maintained.
Senior-led, senior-staffed. Engagements are staffed at the proper experience level relative to portfolio complexity. The credit professionals reviewing your portfolio have decades of banking, audit, and regulatory experience, not entry-level analysts trained on your engagement.
Tri-State roots, national perspective. Based in Fort Washington and serving institutions across Pennsylvania, New Jersey, Delaware, Maryland, and beyond, CRF Advisors brings cross-regional perspective informed by years of work with community banks, savings institutions, credit unions, and financial services companies.
Practical over theoretical. Findings come with realistic remediation paths. Recommendations are calibrated to what institutions can actually implement, not theoretical best practices that won’t survive contact with the operations team.
Direct engagement. The senior credit professional who scopes your engagement is the same one who delivers the findings to your board.

ACL review pairs naturally with CECL implementation and modeling, ALLL methodology review, and independent loan review, whose risk rating findings feed the allowance calculation. Training available for this topic: CECL and ACL training.
