At 106,000 RSF, this is the largest warehouse in the extraction corpus by area. The lease contains multiple rent escalation schedules tied to CPI with a fixed floor and ceiling, and a complex early termination right exercisable in year 4 with a substantial termination fee formula.
Lextract extracted the full CPI escalation provisions including the floor (3%) and ceiling (6%), the termination right details (effective date: month 49, notice period: 12 months), and computed the termination fee formula. All 126 fields were extracted from this high-complexity large-format warehouse lease.

Extraction Time
| Field | Extracted Value | Why It Matters |
|---|---|---|
| Square Footage | 106,000 RSF | Largest warehouse in portfolio — scale increases exposure on all NNN items |
| Annual Base Rent | $1,696,000 | $16/RSF NNN — Inland Empire market rate for Class A warehouse |
| Escalation Type | CPI with 3% floor / 6% ceiling | Bounded CPI allows modeling of best/worst case scenarios |
| Early Termination Right | Month 49 with 12-month notice | Creates lease risk at year 4 — monitor for exercise notice |
| Termination Fee | Unamortized TI + 6 months rent | Substantial fee creates deterrent to early exit |
| Dock Doors | 32 dock-high, 4 grade-level | Critical for industrial tenants evaluating operations fit |
Lextract identifies the escalation type, extracts the CPI index referenced (usually CPI-U or CPI-W), and captures the floor and ceiling percentages as separate fields, enabling analysts to model minimum and maximum rent scenarios.
Lextract extracts the termination effective date, required notice period, termination fee formula, and any conditions (e.g., tenant not in default). These fields are flagged with high importance in the red flag analysis.
