Co-Tenancy and Kick-Out Clauses in Retail Leases: How Anchor Departures Cascade Through Inline Revenue

Key Takeaways

What Co-Tenancy Clauses Actually Do

A co-tenancy clause in a retail lease is a contractual provision that conditions one tenant's rent obligations on the occupancy or operating status of other tenants in the same retail center. The clause creates a contingent liability in the landlord's rent roll: if specified conditions are not met (an anchor tenant departs, overall occupancy drops below a threshold, or certain named tenants cease operations), the affected tenant's rent changes. The change can range from a modest percentage reduction to a full conversion to percentage-rent-only to an outright termination right.

The economic logic is straightforward. An inline tenant in a grocery-anchored shopping center chose that location because the anchor draws foot traffic. The tenant's sales volume, and therefore its ability to pay rent, depends partly on that traffic. The co-tenancy clause is the contractual expression of that dependency. If the anchor leaves and the traffic disappears, the inline tenant's rent adjusts to reflect the diminished location value.

From the landlord's perspective, co-tenancy clauses are a risk multiplier. A single anchor vacancy is already a significant revenue event (anchors typically occupy 30% to 60% of a center's gross leasable area but pay below-market rents per square foot). The co-tenancy clause turns that single event into a multi-tenant revenue problem. As CRE Vertical has noted, in a retail property with active co-tenancy provisions, a 15% occupancy loss can produce a 35% revenue loss. The clause multiplies the financial impact of vacancy across the entire rent roll.

For acquisition underwriting, co-tenancy exposure is one of the most commonly underestimated risks in retail. The clauses sit buried in individual lease abstracts. Aggregating the exposure across all leases in a center requires reading every lease, identifying every co-tenancy trigger, mapping the trigger dependencies across tenants, and modeling the cascading revenue impact under different vacancy scenarios. Most brokers' offering memoranda do not perform this analysis. The acquisition team has to do it.

Three Types of Co-Tenancy

Opening Co-Tenancy

Opening co-tenancy is a condition precedent to a tenant's obligation to open its store and begin paying rent. The clause states that the tenant is not required to open (and in many cases, not required to begin paying base rent) until certain conditions are satisfied. Typical conditions include: one or more named anchor tenants must be open and operating, overall center occupancy must reach a specified threshold (often 70% to 85% of GLA), and in some cases, specific co-tenants (not just anchors) must be open.

Opening co-tenancy is most common in new developments and major redevelopments. The tenant is committing to a lease in a center that does not yet exist or is being substantially rebuilt. The tenant's willingness to pay full rent depends on the center being substantially occupied and anchored as represented. If the developer fails to deliver the promised tenant mix, the tenant's obligation adjusts.

The landlord's risk with opening co-tenancy is a staggered opening problem. If Anchor A opens on schedule but Anchor B is delayed, and six inline tenants have opening co-tenancy clauses requiring both anchors, those six tenants may defer their openings and rent commencement. The landlord carries construction debt service on a center that is generating only partial revenue. The solution is to negotiate the opening co-tenancy thresholds carefully: specify that the threshold is a percentage of committed (not occupied) GLA, include a "deemed satisfaction" date after which the co-tenancy condition lapses regardless of actual occupancy, and limit the list of named anchors to tenants whose leases are already executed.

Operating Co-Tenancy

Operating co-tenancy is an ongoing condition that applies throughout the lease term, after the tenant has opened and begun paying rent. The clause states that if specified conditions are violated during the term (an anchor ceases operations, occupancy drops below a threshold), the tenant's rent obligation changes. This is the most common type of co-tenancy clause and the one that creates the greatest risk for landlords in stabilized acquisitions.

Operating co-tenancy clauses typically specify a two-stage remedy. The first stage is a rent reduction: the tenant pays reduced rent (often 50% of base rent, or percentage rent only, whichever is greater) for a cure period during which the landlord has the opportunity to backfill the vacancy. The second stage is a termination right: if the landlord fails to cure the co-tenancy violation within the cure period (typically 12 to 18 months), the tenant has the right to terminate its lease upon notice.

The critical underwriting question for operating co-tenancy is: what is the probability that the co-tenancy condition will be violated, and what is the revenue impact if it is? The answer depends on the anchor tenant's credit quality, the anchor's remaining lease term, the occupancy threshold specified in the clause, and the current occupancy of the center. A center that is 95% occupied with an anchor whose lease runs 12 more years has lower co-tenancy risk than a center at 82% occupancy with an anchor whose lease expires in 18 months.

Continuous Co-Tenancy

Continuous co-tenancy is a stricter version of operating co-tenancy that requires specified tenants to remain "open and operating" without interruption. Where a standard operating co-tenancy might allow a cure period during which the anchor space is vacant but the landlord is actively re-tenanting, continuous co-tenancy does not. Any interruption in the anchor's operations, even a temporary closure for renovation, can trigger the remedy.

Continuous co-tenancy clauses are less common than standard operating co-tenancy but appear in leases negotiated by national retailers with significant bargaining power. The clause is a reflection of the tenant's view that its sales are directly and immediately tied to the anchor's daily operations. A grocery-anchored center where the grocery store closes for a three-month renovation will see its inline tenants' sales drop immediately. The continuous co-tenancy clause provides immediate relief.

Landlords should resist continuous co-tenancy when possible and negotiate for a minimum interruption period (e.g., the anchor must cease operations for at least 60 or 90 consecutive days before the co-tenancy triggers). This protects the landlord from claims triggered by planned renovations, temporary closures due to natural disasters, or other short-term interruptions that do not reflect a permanent change in the tenant mix.

Trigger Mechanisms

The trigger is the specific condition that converts a co-tenancy clause from dormant language into an active right. The two primary trigger structures are vacancy-based triggers and "open and operating" triggers. The difference between them determines whether a dark store, a tenant in bankruptcy, or a store undergoing renovation will activate the co-tenancy remedy.

Vacancy-Based Triggers

A vacancy-based co-tenancy trigger fires when the occupied gross leasable area of the center falls below a specified percentage. Typical thresholds range from 60% to 80% of total GLA, depending on the tenant's negotiating leverage and the center type. The threshold is usually measured as physical occupancy (leases in place and tenants occupying the space) rather than economic occupancy (leases in place, whether or not the tenant is occupying).

The advantage of vacancy-based triggers for the landlord is their objectivity. Occupancy is measurable. There is no ambiguity about whether a tenant is "operating" or what "operating" means. The disadvantage is that vacancy-based triggers can fire even when the anchor is still present. If a center loses several small inline tenants and drops below the threshold, the co-tenancy triggers regardless of anchor status.

Landlords negotiating vacancy-based triggers should push for: measurement based on GLA occupied by tenants paying rent (not just leased), exclusion of the triggering tenant's own space from the denominator, and a minimum measurement period (e.g., the occupancy must fall below the threshold for at least 90 consecutive days before the trigger fires). These refinements prevent the trigger from firing due to short-term vacancies or measurement timing.

"Open and Operating" Triggers

An "open and operating" trigger fires when a specified anchor tenant (or tenants) ceases to be open and operating at the center. This trigger is tenant-specific rather than center-wide. It does not depend on overall occupancy. It depends on whether the named anchor is physically open for business and conducting retail operations in its space.

The definition of "open and operating" is where the negotiation lives. A tenant-favorable definition requires the anchor to be open for business during customary business hours, operating under its original trade name or a comparable national brand, and occupying at least a specified percentage of its original premises (often 75% or more). A landlord-favorable definition is broader: the anchor is deemed to be "open and operating" if it is paying rent, even if it has ceased retail operations in the space. As the National Law Review has detailed, the negotiation of these definitions is where co-tenancy disputes are typically won or lost.

Named-Anchor vs. Occupancy-Threshold Triggers

Some co-tenancy clauses combine both trigger types. The clause might state that co-tenancy is violated if (a) the named anchor ceases to be open and operating, OR (b) overall center occupancy falls below 70% of GLA. The "or" construction gives the inline tenant protection against both anchor-specific risk and center-wide deterioration.

The "and" construction is more landlord-favorable: co-tenancy is violated only if the named anchor ceases operating AND overall occupancy falls below the threshold. This requires both conditions to be true simultaneously, which is a higher bar for the tenant. The distinction between "or" and "and" in a co-tenancy clause can mean the difference between a clause that fires upon an anchor departure (regardless of overall occupancy) and a clause that fires only when the center is both unanchored and substantially vacant.

The Dark Anchor Problem

A "dark anchor" is a tenant that occupies its space and continues paying rent but has ceased retail operations. The classic example is a department store or big-box retailer that closes its store location but continues paying rent because the lease term has not expired and the cost of early termination exceeds the remaining rent obligation. The space is leased and occupied on paper. The storefront is closed to the public. No customers enter. No foot traffic is generated.

The dark anchor problem exposes a gap in many co-tenancy clauses. If the clause uses a vacancy-based trigger (occupancy below X%), a dark anchor that is still paying rent and occupying its space does not reduce the occupancy calculation. The co-tenancy clause does not fire. But the inline tenants that depend on the anchor's foot traffic are suffering the same revenue decline they would experience if the anchor had vacated entirely.

If the clause uses an "open and operating" trigger, the outcome depends entirely on the definition. A narrow definition that requires the anchor to be "open for business to the public during customary hours" will capture the dark anchor scenario. A broader definition that deems the anchor "open and operating" as long as it is paying rent will not. The difference between these two definitions can represent hundreds of thousands of dollars in annual rent relief for inline tenants.

The dark anchor problem has become more prevalent as large-format retailers have contracted their store counts. A national chain that is closing 200 locations over three years may have dozens of leases where it is more economical to continue paying rent (and sublease or assign if possible) than to negotiate an early termination. These locations become dark anchors, eroding the retail environment for the remaining tenants without technically triggering their co-tenancy protections.

Landlord Strategies for Dark Anchor Risk

Landlords facing a dark anchor have several options, none of them ideal. First, negotiate a lease surrender with the dark anchor, recovering the space in exchange for releasing the anchor from remaining rent obligations. This converts a dark anchor into a standard vacancy, which may trigger co-tenancy clauses but also frees the space for re-tenanting. Second, enforce an operating covenant if the anchor's lease contains one. Many anchor leases include a covenant to operate (as distinguished from a covenant to pay rent), requiring the anchor to maintain operations during the lease term. Enforcement of operating covenants varies by jurisdiction and specific lease language. Third, negotiate co-tenancy modifications with inline tenants, offering rent concessions or other inducements in exchange for waiving or modifying the co-tenancy trigger. This is increasingly common, as WealthManagement.com has reported, with landlords proactively approaching inline tenants before an anchor departure becomes public knowledge.

The Remedies Ladder

When a co-tenancy clause is triggered, the tenant's remedies typically follow a graduated structure. The remedies escalate over time if the landlord fails to cure the co-tenancy violation. This graduated approach gives the landlord a window to re-tenant the space before the most severe consequences take effect.

Stage 1: Rent Reduction (Immediate to 6 Months)

The first remedy is a reduction in base rent. Typical reductions range from 25% to 50% of the contractual base rent. The reduction takes effect either immediately upon the co-tenancy violation or after a short grace period (often 30 to 90 days). The reduced rent reflects the diminished value of the tenant's location in a center that has lost its anchor or fallen below the occupancy threshold.

Some leases specify a fixed percentage reduction (e.g., "Tenant's base rent shall be reduced by 50% during any Co-Tenancy Violation Period"). Others tie the reduction to a formula based on the severity of the violation (e.g., a sliding scale where rent reduction increases as occupancy decreases). The fixed percentage approach is more common because it is simpler to administer and less subject to dispute.

Stage 2: Percentage Rent Only (6 to 12 Months)

If the co-tenancy violation continues beyond the initial cure period, many leases escalate the remedy to a percentage-rent-only structure. The tenant's base rent obligation is suspended entirely, and the tenant pays only a percentage of its gross sales (typically 6% to 10%, depending on the retail category). This remedy ties the tenant's rent to its actual revenue, which has presumably declined due to the loss of anchor-driven traffic.

The percentage-rent-only remedy can result in rent payments far below the contractual base rent. A tenant paying $35 per square foot in base rent on a 2,500 SF space ($87,500 annually) might pay only $30,000 to $50,000 under a 7% percentage rent clause if its annual sales have declined to $450,000 to $700,000 following the anchor departure. The revenue gap for the landlord is significant.

Stage 3: Go-Dark Right (12 to 18 Months)

Some co-tenancy clauses grant the tenant a "go-dark" right if the co-tenancy violation persists beyond a second cure period. The go-dark right allows the tenant to cease operations in its space while continuing to pay reduced rent (or percentage rent only). The tenant remains obligated under its lease but is not required to operate its business. This remedy is less common than rent reduction or percentage rent but appears in leases negotiated by tenants with strong bargaining positions.

The go-dark right is particularly damaging for the landlord because it creates a compounding problem. The anchor has already departed. Now an inline tenant has gone dark. If other inline tenants have co-tenancy clauses tied to overall occupancy (measured by operating tenants, not leased space), the first tenant's exercise of its go-dark right can push the center below additional occupancy thresholds, triggering co-tenancy in other leases. This is the cascading effect that makes co-tenancy clauses so dangerous.

Stage 4: Termination Right (12 to 24 Months)

The most severe co-tenancy remedy is an outright termination right. If the landlord fails to cure the co-tenancy violation within a specified period (typically 12 to 24 months from the initial trigger date), the tenant has the right to terminate its lease upon written notice. The notice period is usually 30 to 90 days. Upon termination, the tenant vacates the space, and the lease is extinguished. The landlord loses both the tenant and the future rent stream.

Termination rights are the landlord's worst-case outcome. The landlord has already lost the anchor. It has been collecting reduced rent or percentage rent from the inline tenant for 12 to 24 months. Now it loses the inline tenant entirely. If multiple inline tenants exercise termination rights simultaneously, the center can spiral from an anchor vacancy problem into a large-scale vacancy event that threatens the viability of the entire property.

Kick-Out Clauses

A kick-out clause (also called an early termination clause or a sales-performance termination clause) gives a tenant the right to terminate its lease if the tenant's own sales fall below a specified threshold. Unlike co-tenancy, which is triggered by the behavior of other tenants, a kick-out clause is triggered by the tenant's own performance. The two provisions address different risks and require different underwriting approaches.

Sales-Performance Triggers

The most common kick-out trigger is a minimum sales threshold. The lease specifies a dollar amount of gross sales (e.g., $500,000 annually or $125,000 per quarter) that the tenant must achieve. If the tenant's sales fall below the threshold for a specified measurement period (typically 12 consecutive months or any two consecutive quarters), the tenant has the right to terminate.

The threshold is usually set at a level where the tenant's store is unprofitable. If the tenant is paying $100,000 in annual rent and its occupancy cost ratio target is 10% to 12%, it needs $833,000 to $1,000,000 in annual sales to meet that target. A kick-out threshold set at $500,000 implies sales that would put the occupancy cost ratio at 20%, well above the tenant's profitability threshold. The kick-out protects the tenant from being locked into a lease at a location that is fundamentally unprofitable.

Notice Periods and Landlord Recapture

Kick-out clauses typically include a notice period between the trigger event and the effective termination date. The notice period gives the landlord time to find a replacement tenant or negotiate to keep the existing tenant. Typical notice periods range from 60 to 180 days.

Many kick-out clauses also include a landlord recapture right. If the tenant delivers a kick-out notice, the landlord has the option (within a specified response period, often 30 days) to offer the tenant modified terms (typically reduced rent) to keep it in the space. If the tenant rejects the modified terms, the termination proceeds. If the tenant accepts, the lease continues at the modified terms, and the kick-out right may be suspended for a specified period.

Some kick-out clauses require the tenant to pay a termination fee (often equal to 3 to 6 months of base rent or the unamortized portion of the landlord's tenant improvement allowance and leasing commissions). The termination fee partially compensates the landlord for the cost of re-tenanting the space and provides some disincentive for the tenant to exercise the kick-out for strategic rather than economic reasons.

Kick-Out vs. Co-Tenancy: Key Differences

The fundamental difference is the trigger event. Co-tenancy is triggered by external factors (anchor departure, center occupancy decline). Kick-out is triggered by internal factors (the tenant's own sales performance). In practice, the two are related: an anchor departure that triggers co-tenancy for some tenants may simultaneously depress sales for other tenants whose leases contain kick-out clauses instead of (or in addition to) co-tenancy clauses.

For underwriting purposes, the two provisions create different risk profiles. Co-tenancy risk is concentrated around anchor lease expirations and anchor credit quality. Kick-out risk is spread across the tenant base and is tied to location-specific sales performance. A center with high co-tenancy exposure but low kick-out exposure is vulnerable to anchor events. A center with high kick-out exposure but low co-tenancy exposure is vulnerable to gradual sales erosion across the tenant base.

The Co-Tenancy Cascade

The most significant risk from co-tenancy clauses is the cascade effect: a single anchor departure triggers co-tenancy in multiple inline leases, and the remedies exercised by those tenants (particularly go-dark rights and termination rights) can trigger additional co-tenancy clauses in other leases, creating a self-reinforcing cycle of revenue loss.

The cascade effect is not hypothetical. It is the standard outcome when an anchor departs a center with co-tenancy exposure. The question for underwriting is not whether the cascade will occur. It is how severe it will be. The severity depends on: how many inline leases contain co-tenancy clauses (the exposure breadth), what remedies those clauses provide (the severity per tenant), and whether any of those remedies can themselves trigger additional co-tenancy clauses in other leases (the feedback loop).

The feedback loop is the most dangerous dynamic. Tenant C exercises its termination right and vacates. Tenant D's co-tenancy clause includes a vacancy-based trigger at 75% occupancy. With the anchor gone (55,000 SF) and Tenant C gone (3,500 SF), total vacancy reaches 58,500 SF out of 200,000 SF, or 29.25% vacancy. Occupancy is now 70.75%, below Tenant D's 75% threshold. Tenant D's co-tenancy triggers not because of the anchor departure directly, but because of Tenant C's departure in response to the anchor. The cascade compounds.

Worked Example: 200,000 SF Grocery-Anchored Center

Consider a 200,000 SF grocery-anchored neighborhood center in a suburban Mid-Atlantic market. The center was built in 2004 and has been stabilized since 2006. The anchor is a regional grocery chain occupying 55,000 SF on a lease that expires in 14 months. The remaining 145,000 SF is occupied by 22 inline tenants ranging from 1,200 SF to 12,000 SF.

Base Case: Stabilized Operations

The center generates $2,440,000 in annual base rent from the anchor, junior anchor, and inline tenants (excluding the pad site ground lease and CAM/tax recoveries). Occupancy is 100%. The center trades at a 7.25% cap rate, implying a value of approximately $33.7M on the base rent alone (before operating expenses and CAM).

Co-Tenancy Exposure Audit

A review of all 22 inline leases reveals that 8 of the 21 inline tenants (representing 38,500 SF and $1,078,000 in annual base rent) have co-tenancy clauses. Four of those clauses are tied to the named grocery anchor. Three are tied to an occupancy threshold of 75% or higher. One is tied to both (an "or" construction). The junior anchor's lease does not contain a co-tenancy clause. The pad site ground lease does not contain one.

Scenario: Anchor Departs at Lease Expiration

The grocery anchor's lease expires and the tenant does not renew. The 55,000 SF space goes vacant. Center occupancy drops from 100% to 72.5% (145,000 SF occupied out of 200,000 SF).

Immediate triggers (named-anchor co-tenancy): Tenants A, B, C, D, and G have named-anchor triggers. Their co-tenancy clauses activate immediately (or after the specified grace period, typically 30 to 60 days). Tenant D's clause fires on the named-anchor prong of its "or" trigger.

Occupancy-threshold triggers: At 72.5% occupancy, the center is below the 75% threshold in Tenants D, F, and H's clauses, and below the 80% threshold in Tenant E's clause. These triggers fire as well. Tenant D's clause would fire on this prong too, but it is already triggered by the named-anchor prong.

Total co-tenancy activation: All 8 inline tenants with co-tenancy clauses are triggered. Every co-tenancy clause in the center fires simultaneously.

Revenue Impact: Months 1 Through 24

The revenue deterioration accelerates over time as co-tenancy remedies escalate. In months 1 through 6, the primary impact is the anchor vacancy ($330,000 per half-year) plus initial rent reductions from triggered co-tenancy clauses. By months 7 through 12, the percentage-rent-only conversions in Tenants B and F take full effect, and the reduced rent is substantially below base rent. By months 13 through 18, Tenant C exercises its termination right and vacates, converting a rent reduction into a full vacancy. By months 19 through 24, the occupancy drop from Tenant C's departure pushes the center further below occupancy thresholds, and revenue continues to decline.

Over the full 24-month period, cumulative revenue loss is approximately $1,937,750, compared to a base-case revenue of $4,880,000 (24 months at $2,440,000 annual). The average revenue loss is approximately 40% of the base case. If the anchor vacancy alone were the only impact (no co-tenancy cascade), the cumulative loss would be $1,320,000 (the anchor's $660,000 annual rent times two years). The co-tenancy cascade adds $617,750 in incremental loss over two years, or approximately 47% on top of the anchor vacancy.

Valuation Impact

The base-case value at a 7.25% cap rate on $2,440,000 NOI (simplified, before operating expenses) is approximately $33.7M. If the acquirer underwrites the center with the anchor departure as a known event, the stabilized NOI must reflect both the anchor vacancy and the co-tenancy drag until the space is re-tenanted and the co-tenancy clauses are cured.

Assuming a 24-month re-tenanting timeline for the anchor space, the weighted average NOI during the unstabilized period is approximately $1,468,750 annually ($2,440,000 less $971,250 in average annual losses including the anchor vacancy and co-tenancy cascade). At a 7.25% cap rate with a 24-month lease-up discount, the acquisition value drops significantly. The co-tenancy cascade accounts for approximately 30% of the valuation haircut, even though the anchor vacancy is the headline event.

2026 Negotiation Trends

The retail leasing market in 2026 reflects lessons learned from two decades of anchor closures, accelerated by the pandemic-era wave of department store and big-box contractions. Landlords and tenants are both more sophisticated about co-tenancy structuring than they were a decade ago, and the negotiation dynamics have shifted in several ways.

Landlord-Side Modifications

Institutional landlords are increasingly pushing to remove or narrow co-tenancy clauses at lease renewal. The negotiation typically takes the form of a trade: the landlord offers a rent concession (reduced base rent, additional TI allowance, or a free-rent period) in exchange for the tenant agreeing to delete its co-tenancy clause or convert a termination right into a rent-reduction-only remedy. This approach is economically rational when the expected value of the co-tenancy exposure exceeds the cost of the concession.

Specific landlord-side trends in 2026 include:

• Narrowing "open and operating" definitions. Landlords are insisting on definitions that include replacement tenants of comparable quality and size, not just the original named anchor. If the grocery closes but a comparable grocer takes the space within the cure period, the co-tenancy is cured regardless of the name on the sign.
• Adding cure-period extensions. Landlords are negotiating for 18- to 24-month cure periods (up from the 12-month standard) and for the right to extend the cure period by an additional 6 months if the landlord can demonstrate active re-tenanting efforts (a signed letter of intent, for example).
• Replacing termination rights with rent caps. Instead of granting an outright termination right, some landlords are negotiating a "rent floor" structure: if co-tenancy is violated, the tenant pays the greater of percentage rent or 60% to 75% of base rent, with no termination right. The tenant gets rent relief but cannot walk away.
• Sunset provisions. Co-tenancy clauses that expire after a specified period (e.g., the first 5 or 7 years of the lease term) are becoming more common. The logic is that after the tenant has established its customer base, it is less dependent on anchor traffic and the co-tenancy protection is less justified.

Tenant-Side Modifications

National tenants with strong negotiating leverage are pushing back on landlord attempts to narrow co-tenancy protections. Tenant-side trends include:

• Expanding the definition of "anchor." Tenants are defining "anchor" not just as the single largest tenant but as any tenant occupying more than a specified threshold (often 10,000 or 15,000 SF). This protects against the departure of a junior anchor whose closure would materially affect foot traffic even if the primary anchor remains.
• Adding "quality" requirements. Some tenants are insisting that replacement tenants meet minimum quality standards (e.g., a nationally recognized brand, investment-grade credit, or a specified minimum number of operating locations). A landlord who backfills an anchor space with a discount liquidator or a self-storage operator does not cure the co-tenancy, even if the space is occupied.
• Cross-center co-tenancy. In multi-property portfolios, some national tenants are negotiating cross-center co-tenancy provisions that tie their rent at one location to the occupancy or anchor status at a nearby property owned by the same landlord. This is rare but reflects the growing sophistication of tenant lease negotiation.

The Co-Tenancy Modification Trade

The most significant trend is the proactive co-tenancy modification. Landlords who know an anchor departure is likely (because the anchor has provided notice, because the anchor's credit is deteriorating, or because the anchor's lease is approaching expiration with no renewal discussions) are approaching inline tenants before the departure to negotiate modifications. The Tango Analytics co-tenancy guide notes that this proactive approach is increasingly standard practice among institutional retail landlords, particularly REITs with portfolio-level co-tenancy exposure.

The typical trade: the landlord offers 6 to 12 months of rent reduction (10% to 20% below the current rate) in exchange for the tenant agreeing to a modified co-tenancy clause with a longer cure period, a reduced remedy (rent reduction instead of termination), or a sunset provision. The landlord's economic analysis compares the certain cost of the rent concession against the expected cost of the co-tenancy exposure under the existing clause. If the expected co-tenancy cost is $150,000 over three years and the rent concession costs $40,000, the trade is attractive.

Co-Tenancy Risk Underwriting Checklist

When underwriting a retail acquisition with co-tenancy exposure, the following analysis should be performed as part of the lease-by-lease review. This checklist is not exhaustive, but it covers the most material items.

1. Identify every co-tenancy clause in the rent roll. Read every inline lease. Do not rely on the broker's offering memorandum or the seller's lease abstract. Co-tenancy clauses are sometimes buried in lease amendments or riders that are not reflected in the abstract. Count the number of leases with co-tenancy, the total SF exposed, and the total annual rent exposed.

2. Map the trigger dependencies. For each co-tenancy clause, identify the trigger: named anchor, occupancy threshold, or both. Create a dependency map showing which anchor departures or occupancy declines would trigger which co-tenancy clauses. Look for feedback loops where one tenant's termination can push occupancy below another tenant's threshold.

3. Assess anchor credit and lease term. The probability of a co-tenancy trigger is directly tied to the probability of an anchor departure. Review the anchor tenant's credit quality (public filings, credit ratings, store count trends), the remaining lease term, and any renewal options. An anchor with 2 years remaining and no renewal option is a near-term risk. An anchor with 12 years remaining and investment-grade credit is a remote risk.

4. Model the downside scenario. Build a pro forma scenario where the anchor departs and all co-tenancy clauses are triggered simultaneously. Model the revenue impact month by month, reflecting the remedy escalation (rent reduction in the first period, percentage rent in the second, termination in the third). Compare the downside NOI to the base case. The gap is the co-tenancy exposure.

5. Evaluate cure feasibility. Assess whether the landlord can realistically re-tenant the anchor space within the cure periods specified in the co-tenancy clauses. If the cure period is 12 months and the market re-tenanting timeline for that size and location is 18 to 24 months, the landlord is unlikely to cure before termination rights activate.

6. Check for dark-anchor language. Review the "open and operating" definitions in each co-tenancy clause. Determine whether a dark anchor (paying rent but not operating) would trigger the co-tenancy. If the language does not cover the dark-anchor scenario, adjust the risk assessment to reflect the possibility that the anchor could go dark without triggering co-tenancy remedies for inline tenants.

7. Price the exposure into the acquisition. The co-tenancy exposure should be reflected in the acquisition price, either as a direct deduction from value (the expected cost of the downside scenario, probability-weighted) or as an adjustment to the cap rate (a higher cap rate to compensate for the contingent liability). For a center with significant co-tenancy exposure, a 25 to 75 bps cap rate adjustment is common, depending on the probability and severity of the trigger event.
