Seminar on New Lease Accounting Standards
Proship Inc., headquartered in Chiyoda, Tokyo, is hosting a series of 14 free online seminars to prepare businesses for the application of new lease accounting standards starting April 2027. The fourth session focuses on how to document ‘reasonable certainty’ and the strategies for setting shorter lease terms, a critical aspect of practical implementation.
Importance of the Seminar Theme
The upcoming new lease accounting standards will be mandatory from the fiscal year 2027, and determining lease terms is one of the more time-consuming topics companies must tackle. The length of a lease directly affects the calculation of lease liabilities, which in turn has significant implications for financial statements. Many organizations are inclined to define lease terms as equivalent to contracted durations. However, they must substantiate whether the use of extension or termination options is ‘reasonably certain’. This requires objective evidence and documentation to ensure compliance, rather than relying solely on subjective judgments.
In light of this, the fourth seminar aims to clarify how to integrate the concept of ‘reasonable certainty’ into practical corporate decision-making and provide specific strategies for organization.
Key Points of the Seminar
This session will help participants navigate the crucial issues relating to lease term settings and offer practical methods tailored to business applications.
- - Fundamental Concepts of ‘Reasonable Certainty’: A consolidated understanding of what constitutes reasonable certainty in lease accounting.
- - Understanding the Economic Incentives: Identifying the core economic incentives that guide lease term decisions.

- - Documentation Strategies for Auditors: Approaches to document lease terms that are compliant with upcoming audits, alongside reference examples.
