Now let me analyze the assumption register and identify key issues.

## FY2026 Assumption Register Review

Based on my analysis of `data/assumptions_fy2026.csv`, I've identified several issues requiring attention:

### **Critical Issues**

**1. Unowned Assumptions**
- **A-16 (Merit increase: 3.5%)** — No owner assigned. This People/compensation assumption needs clear ownership for monitoring and updates.

**2. Unsupported Assumptions** (Missing Source Documentation)
- **A-04 (Average headcount: 23.75 FTE)** — No source listed. This is a foundational People assumption that should reference payroll data, headcount plan, or budget documents.

### **Stale Assumptions** (Not Reviewed Recently)

These haven't been validated in 1+ months and should be refreshed:

| ID | Assumption | Area | Last Reviewed | Days Overdue |
|---|---|---|---|---|
| **A-09** | Inventory turns (6.50) | Working capital | 2025-03-14 | ~569 days ⚠️ |
| **A-13** | Line of credit interest rate (7.25%) | Financing | 2025-06-02 | ~489 days ⚠️ |
| **A-19** | Outbound freight % of revenue (3.3%) | Margin | 2025-10-17 | ~17 days |

**A-09 is critically overdue** — last reviewed March 2025, which is nearly 7 months ago. Inventory assumptions are frequently impacted by supply chain changes and should be validated quarterly at minimum.

**A-13 should be reviewed** — interest rates changed significantly in 2025-2026. The June 2025 snapshot may not reflect current lending rates; coordinate with Dana Whitfield to validate this persists.

### **Status Summary**

✅ **Well-maintained**: 17 of 20 assumptions have recent reviews (Nov-Dec 2025)  
⚠️ **Action required**: 3 assumptions need immediate review (A-09, A-13, A-19)  
❌ **Governance gaps**: 1 unowned + 1 unsupported assumption

### **Recommendations**

1. **Assign owner to A-16** — Designate compensation/HR lead (suggest Elena Brandt or Marcus Oyelaran) for merit increase assumption.
2. **Document source for A-04** — Update with payroll register reference or headcount plan document.
3. **Prioritize A-09 refresh** — Have Tomas Herrera or inventory lead revalidate inventory turns against current turnover data.
4. **Confirm A-13** — Dana Whitfield should confirm line of credit rate is still 7.25% under current credit agreement; if rates have been repriced, update immediately.

Would you like me to create a formal memo or action items list from this review?
