When evaluating your lease term, the term "Reasonably Certain" is important.  “Reasonably Certain” is considered a high threshold of probability under ASC 842. At the lease commencement date, an entity assesses whether the lessee is reasonably certain to exercise or not to exercise an option by considering all economic factors relevant to that assessment — contract- based, asset-based, market-based, and entity-based factors. An entity’s assessment often will require the consideration of a combination of those factors because they are interrelated. Examples of economic factors to consider include, but are not limited to, any of the following: 1. Contractual terms and conditions for the optional periods compared with current market rates, such as: 2. Significant leasehold improvements that are expected to have significant economic value for the lessee when the option to extend or terminate the lease or to purchase the underlying asset becomes exercisable. 3. Costs relating to the termination of the lease and the signing of a new lease, such as negotiation costs, relocation costs, costs of identifying another underlying asset suitable for the lessee’s operations, or costs associated with returning the underlying asset in a contractually specified condition or to a contractually specified location.  4. The importance of that underlying asset to the lessee’s operations, considering, for example, whether the underlying asset is a specialized asset and the location of the underlying asset. **Accounting Guidance Referenced:** -
