Arrows show whether the value sits above or below the peer median. Colour shows whether that side is favourable for the measure: green favourable, red unfavourable, grey where neither side is (for example, a lower loan-to-core-deposit ratio is favourable, so a negative gap is green). Peer medians cover the same source, form, period, institution type and asset band, and count this institution in its own cohort. The peer line on every chart reads the same cohort. Regulatory definitions differ from FORFI quarterly estimates.

How to interpret differences
Flows cover the selected income window. Balance-sheet amounts, members and staffing are as of the filing date.
Published FDIC references use the regulator's own averaging, annualization and adjustments; the convention selector changes FORFI calculations only. Source-provided averages are used when available; endpoint fallbacks are labeled estimates.
Missing inputs remain unavailable. Credit-union margins use average assets and are not comparable with bank margins over earning assets.
AFS + HTM securities exclude deposits at other institutions. Broader investment totals may overlap cash; do not add them to cash without reconciling components.
