What is co-tenancy in a shopping center lease?

Co-tenancy is a lease provision allowing inline tenants to reduce rent (typically to a percentage-of-sales structure) or terminate the lease if specified anchor stores go dark or occupancy drops below a threshold (commonly 60-70% of GLA). Anchor health is the largest risk factor in shopping center cash flow because a single anchor closure can trigger rent reductions across multiple inline leases. Ilora.ai flags every co-tenancy clause in lease abstracts and models the rent impact of anchor scenarios.

How is shopping center NOI calculated?

Shopping Center NOI = Effective Gross Income (base rent + percentage rent + CAM recoveries + tax recoveries + insurance recoveries + ancillary income such as signage and pop-up) − Operating Expenses (CAM-passable expenses, non-recoverable G&A, management fee, insurance, taxes net of recoveries). Recovery accuracy is the largest leakage source — shopping centers with sloppy CAM reconciliation routinely under-recover 50-150 basis points of NOI.

Which REITs own shopping centers?

The dominant public shopping center REITs are Kimco Realty (KIM, ~530 properties grocery-anchored), Regency Centers (REG, ~480 grocery-anchored), Brixmor Property Group (BRX, ~360 community centers), SITE Centers (SITC, ~100 power centers), and Federal Realty (FRT, ~100 mixed-use lifestyle). Net lease retail REITs (O, NNN, EPRT, ADC, STOR) own pad sites under shopping center anchors via single-tenant ground leases.

Shopping Center KPIs.

Shopping Centers are open-air, anchor-plus-inline retail properties — neighborhood centers (60-100K SF, grocery-anchored), community centers (100-350K SF), power centers (250-600K SF, big-box anchors), and lifestyle centers (200-500K SF, upscale dining + soft goods). Performance is measured in sales PSF, occupancy cost ratio (rent ÷ sales), CAM-recovery accuracy, anchor-tenant credit, and co-tenancy compliance. Anchor-store health (grocer, drug, big-box) is the single most important risk factor — co-tenancy clauses in inline leases let tenants reduce rent or terminate when anchors go dark. The dominant comparable REITs are KIM (Kimco), REG (Regency), BRX (Brixmor), SITC (SITE Centers), and FRT (Federal Realty). Ilora.ai ingests rent rolls, sales-reporting (where available), CAM reconciliation, lease abstracts (with co-tenancy + exclusivity clauses), and tenant-credit metrics, then benchmarks occupancy cost, sales PSF, and CAM-recovery accuracy against KIM, REG, BRX, SITC, FRT comparables. ICSC, BOMA, and ULI Retail Council are the canonical industry organizations.

15 definitions · Sector: COMMERCIAL · Used by Ilora.ai specialist AI agents

NOI: Total revenue minus operating expenses (excludes financing and capital costs). The primary measure of property-level profitability.
Cap Rate: Net Operating Income divided by current property value. Expresses unleveraged annual yield as a percentage.
DSCR: Net Operating Income divided by total annual debt service. Lender-required cushion measure; below 1.0 means NOI cannot cover debt.
LTV: Loan amount divided by property value. Lower LTV = lower lender risk.
OER: Operating expenses divided by gross revenue. Lower is better, but varies by property type (hotels run higher than triple-net retail).
GRM: Property value divided by gross annual rental income. Quick valuation shortcut; less precise than cap rate.
IRR: Annualized return on investment accounting for time value of money across the full hold period.
CoC: Pre-tax annual cash flow divided by total cash invested. Measures the cash yield, not total return.
DCF: Valuation method that projects future cash flows and discounts them to present value at a chosen rate.
TTM: A rolling sum of the most recent 12 months. Smooths seasonality for KPI comparisons.
WALT: Average remaining lease term weighted by rent. Higher WALT = lower rollover risk.
NNN: Triple-net lease — tenant pays base rent plus property taxes, insurance, and maintenance separately.
CAM: Tenant-recoverable expenses for shared building/center upkeep. Often disputed in audits.
TI: Cash allowance from landlord to tenant for build-out. Amortized over lease term.
RSF: Tenant's usable square footage plus a pro-rata share of common areas. The basis for rent calculation.
