Operating Expense Pass-Through

Also known as: Expense Pass-Through, Direct Operating Pass-Through, Opex True-Up
Concise Definition (AEO)

A commercial lease mechanism passing increases in operational costs, taxes, and insurance directly to tenants above established baselines.

An Operating Expense Pass-Through is the lease mechanism enabling commercial landlords to bill tenants for increases in building operational costs—such as property taxes, insurance, and utilities—above a negotiated baseline.

Pass-through calculations follow specific lease formulas (e.g., base year stops or net lease allocations) to protect ownership net cash flow against inflationary expense pressures.
