How to document and defend CECL qualitative factors

Document and be able to defend qualitative factors under CECL 

Financial institutions need to be able to explain and show how they developed Q factors for their allowance for credit losses. Modifications to the CECL calculation should be reasonable, supportable, and audit-ready.

Key topics covered in this post: 

Documenting & defending Q factors: Don't play a guessing game.

If you’ve been tasked with completing a CECL calculation, you know that qualitative factors (Q factors) can be one of the most challenging parts of the process. They require a mix of judgment, data, and defensibility—without clear instructions from regulators on exactly how to apply them.

But documenting and defending Q factors doesn’t have to be a guessing game. With the right approach, you can ensure your adjustments are well supported, transparent, and easy to explain to auditors and examiners. Let’s walk through the key steps to identifying, documenting, and defending CECL Q factors.

Abrigo's Qualitative Adjustment Scorecard helps you implement a structured Q factor framework

What are CECL qualitative factors?

CECL qualitative factors are adjustments made to credit loss estimates to account for risks that historical loss data and quantitative models alone don’t fully capture. These CECL adjustments could encompass economic shifts, changes in your loan portfolio, or even adjustments in underwriting standards. Essentially, Q factors help ensure your reserve levels reflect not just past performance but also what’s happening now and what’s expected in the future.

Why is documenting Q factors so important?

The CECL standard (ASC 326) gives financial institutions significant latitude in how they apply qualitative factors. But that latitude makes it even more critical to document and justify their approach.

A well-structured framework for qualitative adjustments to the allowance for credit losses (ACL) under CECL enhances transparency, consistency, and defensibility. It ensures that modifications are reasonable, supportable, and audit ready.

Proper documentation is key for:

  • Regulatory and audit expectations – Examiners and auditors will expect clear, well-supported explanations for your CECL adjustments.
  • Transparency and consistency – Having a structured approach that is documented ensures your CECL methodology holds up over time and can be easily reviewed.
  • Defensibility – If you ever need to justify your reserve levels for credit losses, strong documentation will be your best friend.

How to identify CECL Q factors

Taking the time to understand how to identify CECL qualitative factors makes it easier to document and defend them later on.

Step 1: Start with your historical loss data

Your financial institution’s historical loss experience forms the foundation of your CECL estimate. Before making adjustments, understand what your baseline numbers look like and what trends they show.

Step 2: Consider current and expected conditions

This is where Q factors come into play. Ask yourself:

  • Are economic conditions improving or deteriorating (GDP growth, unemployment, inflation)?
  • Have there been any major industry shifts that could impact our borrowers?
  • Have we changed our lending practices (new products, risk appetite)?

Step 3: Align Q factors with risk categories

To keep things structured, organize your qualitative factors into key categories:

  • Economic environment – National, regional, and local economic trends.
  • Industry conditions – Market shifts, regulatory changes, sector-specific risks.
  • Portfolio changes – Credit mix, loan concentrations, underwriting adjustments.
  • Borrower-specific factors – Changes in creditworthiness, collateral values.
  • Regulatory/legal factors – Compliance changes, litigation risks.

Step 4: Develop a structured framework for Q factor adjustments

One of the most effective ways to ensure consistency and defensibility in your qualitative factor adjustments is to implement a structured Q factor framework, such as Abrigo’s Qualitative Adjustment Scorecard. The scorecard includes identification of high-water economic scenarios to define appropriate risk brackets and enables tailoring to each allowance pool.

This approach provides a reliable mechanism for measuring and benchmarking qualitative factors across your institution. Benefits of a structured CECL qualitative framework include:

  • Consistency – Ensures Q factor adjustments are applied systematically across reporting periods.
  • Measurability – Establishes standards and benchmarks for assessment.
  • Back-testing capability – Allows comparison of past predictions with actual performance.
  • Comparability – Aligns your methodology with peer institutions for greater credibility.

Documenting qualitative factors under CECL

Once you’ve identified your Q factors, documentation is the next step. A good approach includes:

  • Describing each factor – Be specific about what’s changing and why it matters.
  • Backing it up with data – Use economic reports, industry benchmarks, and internal analyses.
  • Explaining your adjustments – Show how each factor translates into an impact on your CECL estimate.
  • Tracking changes over time – Document shifts in methodology and why they occurred.

CECL Q factor documentation checklist


To make documenting Q factors easier, here's a simple checklist to follow:

1. Identify and define relevant Q factors.

2. Support each factor with data from reliable sources.

3. Document the assumptions behind each adjustment.

4. Clearly explain any changes from previous periods.

5. Ensure consistency and maintain internal approvals.

6. Keep records organized for audit and regulatory review.

Consider adding a similar checklist to any CECL procedures your financial institution develops.

Tips for backing up your Q factors

Qualitative factors remain a hot-button issue during audits and exams because they can lead to wide swings in the allowance for credit losses if left unchecked. Follow these recommendations to ensure your bank or credit union can defend qualitative factors and their role in the allowance calculation.
  • Be consistent – Apply your methodology the same way each period unless justified otherwise.
  • Use hard data where possible – While Q factors involve judgment, tie them to real metrics whenever you can.
  • Involve the right people – Your finance, credit, and risk teams should all have a say in setting qualitative factors.
  • Anticipate questions – Auditors and regulators will ask about your methodology. Be ready with clear, well-organized documentation.

How often should financial institutions update Q factors?

At a minimum, review and update your Q factors quarterly. However, if there are significant changes in economic conditions, regulatory requirements, or your loan portfolio, you may need to adjust them more frequently. Taking the time to document your CECL Q factors properly will make life easier during audits. More importantly, it will also ensure that your reserve levels reflect the real risks in your portfolio.
