[GOAL] Produce a final recommendation on whether to deploy a mid-quarter recalibration of the Retail Cards CECL (expected credit loss) allowance model in time for Q2 2026 financial close, balancing model performance improvement, risk-data/control readiness, audit/reporting constraints, and capital impact.

[R0.1] Credit Risk Model Owner (Retail Cards) (speak, public): Let's discuss the Q2 2026 CECL allowance model recalibration. We've completed the SAS-to-Python parity check with 1,250 scenarios and a max delta of 0.02% ECL. Our out-of-time test shows improved PD MAE from 0.38% to 0.29% and Gini coefficient from 0.42 to 0.46. What are the data refresh timing and deployment readiness looking like?
[R0.2] Risk Data Engineering Lead (speak, public): Our risk data mart refresh SLA is a nightly batch that starts at 03:00 ET and data is available by 07:00 ET. Currently, we have some gaps in feature completeness - for the latest month, income refresh is missing for 2.6% of accounts and origination FICO is missing for 1.3%. We're managing 27 upstream tables and 2 vendor files delivered via SFTP. On the controls side, lineage documentation covers 19 sources, but we still have 8 sources missing documentation. Can you share more about the model changes you're planning and the expected timeline for deployment?
[R0.3] Finance Controller, Allowance & Reporting (speak, public): The quarter-end close timeline is tight - Q2 books close on July 6, 2026, and the external reporting package is due on July 12, 2026. Any methodology change after June 20, 2026, will trigger approximately 240 incremental audit hours. Can you confirm if the data gaps you're seeing will be resolved before the model deployment, and what's the plan to address the missing lineage documentation for 8 sources?

[R1.1] Credit Risk Model Owner (Retail Cards) (speak, public): We've made key parameter changes in the recalibration, including a 12-month PD shift of -14 bps for prime and -6 bps for near-prime bands. The model governance schedule shows our annual CECL validation is due August 15, 2026, and we had one medium finding in the last validation. Regarding deployment readiness, can you confirm if the data refresh timing will be sufficient for our Q2 close? Additionally, what's the status on resolving the feature completeness gaps you've identified?
[R1.2] Risk Data Engineering Lead (speak, public): We've confirmed our nightly batch process completes by 07:00 ET, which should be sufficient for Q2 close. We're still working on resolving the feature completeness gaps - income refresh for 2.6% of accounts and origination FICO for 1.3% are our current priorities. On the controls side, we're addressing the missing lineage documentation for the remaining 8 sources. Can you help me understand the expected magnitude of reserve changes due to your model recalibration? Will this be a significant change that might trigger any executive escalation thresholds?
[R1.3] Finance Controller, Allowance & Reporting (speak, public): The current allowance position for Retail Cards is an ACL of $1,260,000,000 with a coverage ratio of 6.8% as of March 31, 2026. Regarding the expected magnitude of reserve changes, we'll need to assess that once the recalibration is complete. I can share that ACL increases reduce CET1 by 9 bps per $100,000,000. Let's focus on confirming data readiness and audit implications first. Can you provide an update on when you expect to complete the remaining lineage documentation and resolve the feature completeness gaps?

[R2.1] Credit Risk Model Owner (Retail Cards) (speak, public): We've made significant improvements in our model performance with the recalibration, and we're on track to meet the Q2 deployment timeline.
