Understanding the Pass-Through Clause in Mississippi Real Estate Transactions

A pass-through clause is a critical provision in a commercial real estate lease agreement, particularly in a triple net lease (NNN), where the tenant agrees to pay a share of the property's operating expenses, such as property taxes, insurance, and maintenance, in addition to base rent. In Mississippi, this clause effectively "passes through" these costs from the landlord to the tenant, making it essential for both parties to understand its mechanics and financial implications before signing a contract.

This analysis outlines the core function of a pass-through clause, its common structure within Mississippi leases, and the key considerations for tenants to avoid unexpected financial burdens. The central takeaway is that while pass-through clauses are standard, their specific terms are negotiable, and a thorough review of the Operating Expense (OpEx) definitions is the most important step for a tenant to protect their financial interests.

What Exactly is a Pass-through Clause?

In a standard commercial lease, a landlord might pay all property expenses and simply charge a higher, all-inclusive rent. A pass-through clause creates a different financial model. It separates the base rent from the property's operating costs. The landlord pays these costs initially but then "passes them through" to the tenant, usually on a proportional basis (e.g., if a tenant leases 20% of a building, they pay 20% of the annual property tax increase). This structure is fundamental to a triple net lease, a common arrangement for single-tenant retail or industrial properties in Mississippi. The clause shifts the burden of variable costs to the tenant, providing the landlord with a more predictable net income.

Common Structures for Pass-throughs in Mississippi Leases

Pass-through clauses are not one-size-fits-all. In Mississippi, they typically follow one of these models:

• Base Year Clause: This is a frequent structure. The lease establishes a "base year" (often the calendar year the lease begins). The tenant agrees to pay their proportional share of any increase in operating expenses over the amount incurred during that base year. For example, if property taxes in the base year were $10,000 and rise to $11,000 the following year, the tenant pays their share of the $1,000 increase.
• Expense Stop Clause: Here, the landlord sets a fixed dollar amount, the "expense stop," for annual operating expenses. The tenant is responsible for paying their share of any expenses that exceed this predetermined stop. This method can be preferable for tenants if the stop is set at a reasonable, market-based level.

The table below illustrates a simplified comparison of these two models for a tenant leasing 25% of a building.

Key Considerations for Mississippi Tenants

Before agreeing to a pass-through clause, a tenant must conduct rigorous due diligence. Title insurance protects against ownership claims, but lease diligence protects against financial surprises.

1. Scrutinize Defined Operating Expenses: The lease will have a section defining what constitutes a "reimbursable" operating expense. Tenants must ensure this list is fair and excludes landlord-specific costs. Negotiate to exclude capital expenditures (e.g., roof replacement), leasing commissions, and debt service. Request a copy of the previous year's actual expenses to benchmark the base year or expense stop.
2. Audit Rights: Always negotiate for the right to audit the landlord's operating expense records. This is a critical check-and-balance that ensures you are only paying for legitimate, pass-through expenses as defined in the lease. Most landlords will agree to a reasonable audit clause, often with the provision that the tenant pays for the audit unless a significant error (e.g., over 5%) is found.
3. Understand Mississippi Property Taxes: Property tax is a major component of pass-through costs. In Mississippi, property is assessed at its true value, and tax rates are set by local authorities. Understanding potential tax increases in your specific county (e.g., Hinds, Harrison, Rankin) is vital for forecasting your future financial obligations.

Potential Pitfalls and How to Avoid Them

The primary risk for a tenant is an ambiguously worded pass-through clause that allows the landlord to pass through excessive or inappropriate costs. Vague language can lead to disputes over maintenance vs. capital improvements, or administrative fees. Another pitfall is failing to account for a partially occupied building; your lease should specify that operating expenses are calculated as if the building were 95% occupied, preventing you from subsidizing costs for vacant spaces.

In conclusion, a pass-through clause is a powerful tool that allocates financial risk in a Mississippi commercial lease.

• Tenants must negotiate the specific definitions within the operating expense clause.
• Always secure the right to audit expense statements.
• Base year and expense stop models have different long-term financial impacts. A clear understanding of this provision is not just advisable—it is essential for the financial health of your business.
