--- Round 0 ---
[R0.1] Credit Risk Model Owner (Retail Cards) (speak, public): Good morning, everyone. To determine whether we can safely deploy the mid-quarter recalibration of our Retail Cards CECL allowance model for Q2 2026, I'd like to confirm a few key points. First, can we confirm the data refresh timing? When can we expect the latest data to be available for the recalibration?
[R0.2] Risk Data Engineering Lead (speak, public): Our risk data mart refresh SLA is as follows: the nightly batch starts at 03:00 ET, and the data is available by 07:00 ET. This should support the recalibration timeline for Q2 2026.
[R0.3] Finance Controller, Allowance & Reporting (speak, public): To ensure we can deploy the mid-quarter recalibration for Q2 2026, I need to understand the potential impact on our financial reporting and audit requirements. Can you provide an update on the model's performance improvement and any changes to the methodology? Additionally, I'd like to know if there are any outstanding issues with the risk data and controls that could affect our ability to report accurately.

--- Round 1 ---
[R1.1] Credit Risk Model Owner (Retail Cards) (speak, public): The recalibration has shown improved performance, with the PD MAE decreasing from 0.38% to 0.29% and the Gini coefficient improving from 0.42 to 0.46. The key parameter change includes a 12-month PD shift of −14 bps for the prime band and −6 bps for the near-prime band. Our implementation packaging has also been completed with a SAS-to-Python parity check across 1,250 scenarios, showing a maximum delta of 0.02% ECL. Regarding risk data and controls, I'd like to hear from Risk Data Engineering Lead about any outstanding issues that could affect our ability to report accurately.
[R1.2] Risk Data Engineering Lead (speak, public): We've made progress on risk data readiness, but there are a few outstanding issues. Our feature completeness for the latest month shows that income refresh is missing for 2.6% of accounts, and origination FICO is missing for 1.3%. We have 11 open Jira stories related to model deployment, with 3 marked as release-blocking. Additionally, our lineage documentation covers 19 sources, but 8 sources are still missing documentation. These are the key areas we're addressing to ensure risk data and control readiness for the recalibration deployment.
[R1.3] Finance Controller, Allowance & Reporting (speak, public): Thank you for the updates. To summarize, the recalibration shows improved model performance with a PD MAE decrease from 0.38% to 0.29% and a Gini coefficient improvement from 0.42 to 0.46. However, there are some outstanding issues with risk data readiness, including missing income refresh for 2.6% of accounts and origination FICO for 1.3%, as well as 3 release-blocking Jira stories and incomplete lineage documentation for 8 sources. Given these details, I'd like to assess the potential impact on our Q2 2026 financial reporting and audit requirements. Can we confirm if the current timeline allows for the recalibration to be reportable and auditable within the quarter-end timetable?

--- Round 2 ---
[R2.1] Credit Risk Model Owner (Retail Cards) (speak, public): To assess whether we can meet the Q2 2026 quarter-end timetable, I'd like to confirm a few more details. Risk Data Engineering Lead, can you provide an update on when you expect to resolve the 3 release-blocking Jira stories and complete the lineage documentation for the remaining 8 sources? Additionally, Finance Controller, Allowance & Reporting, are there any specific audit or reporting constraints that we need to be aware of that could impact our ability to deploy the recalibration on time?
[R2.2] Risk Data Engineering Lead (speak, public): We're making progress on the release-blocking Jira stories, with an expected resolution by Apr 25, 2026, which should give us sufficient time for testing before the Q2 2026 deployment. Regarding lineage documentation, we're on track to complete the remaining 8 sources by Apr 20, 2026. However, I want to highlight that our current production stability has shown 5 Sev2 incidents in the last 90 days, with a mean time to recover of 46 minutes. While this isn't directly related to the recalibration, it's something to consider when planning the deployment.
[R2.3] Finance Controller, Allowance & Reporting (speak, public): Thank you for the updates. To ensure we meet the Q2 2026 quarter-end timetable, I'd like to highlight that any methodology change after June 20, 2026, will trigger approximately 240 incremental audit hours. Given the current status of the release-blocking Jira stories and lineage documentation, I believe we are on track. However, I need to assess the potential impact of the recalibration on our allowance position. Credit Risk Model Owner (Retail Cards), can you provide an estimate of the expected change in the allowance due to the recalibration?

--- Round 3 ---
[R3.1] Credit Risk Model Owner (Retail Cards) (speak, public): I'd like to clarify that while I can share the overall impact direction, I'm not at liberty to disclose the exact allowance change amount publicly. Let's discuss this further privately if needed. To answer your question directly, Finance Controller, the recalibration is expected to result in a change to the allowance position, but I can confirm that our analysis indicates it will be within our established sensitivity thresholds. Risk Data Engineering Lead, can you confirm if the data refresh timeline and production stability will support running the recalibrated model through our standard quarter-end stress testing?
[R3.2] Risk Data Engineering Lead (speak, private to=Credit Risk Model Owner (Retail Cards)): Regarding the data refresh timeline, we've confirmed that our nightly batch process starts at 03:00 ET and data is available by 07:00 ET, which should support running the recalibrated model through our standard quarter-end stress testing. However, I need to clarify that our production stability, while not directly related to the recalibration, has shown some incidents in the last 90 days. To provide a more detailed assessment on production stability and its potential impact, I'd like to discuss this further privately.
[R3.3] Finance Controller, Allowance & Reporting (speak, public): To finalize our decision on deploying the mid-quarter recalibration for Q2 2026, let's summarize the key points. The recalibration shows improved model performance, with a PD MAE decrease from 0.38% to 0.29% and a Gini coefficient improvement from 0.42 to 0.46. Risk data readiness has some outstanding issues, but they're being addressed, with 3 release-blocking Jira stories expected to be resolved by Apr 25, 2026, and lineage documentation for 8 sources to be completed by Apr 20, 2026. The expected change in allowance is within our established sensitivity thresholds. Given the current timeline and progress, I believe we can deploy the recalibration for Q2 2026. However, we must ensure that all issues are resolved and the audit requirements are met. I recommend we proceed with the deployment while closely monitoring the risk data readiness and audit constraints.
