This Roadmap provides Deloitte’s insights into and interpretations of the guidance in ASC 805 on business combinations, pushdown accounting, common-control transactions, joint ventures, and asset acquisitions. The updated edition reflects guidance issued through May 30, 2025.

The accounting frameworks under ASC 805 for business combinations, pushdown accounting, common-control transactions, and asset acquisitions have been in place for many years. Nevertheless, new guidance and updates are periodically issued, reflecting evolving views and interpretations of these frameworks. As a result, entities must exercise significant judgment not only in applying longstanding principles but also in integrating the latest guidance to address current transaction scenarios.

This Roadmap will help entities navigate the complexities of the guidance in ASC 805, including determining whether an acquisition is a business combination or an asset acquisition; accounting for business combinations, asset acquisitions, and joint ventures; and applying pushdown accounting.

Also available is the latest edition of On the Radar, which includes a high-level summary of the accounting for business combinations under ASC 805 and related guidance on asset acquisitions, pushdown accounting, common-control transactions, and joint venture formations.

Be sure to check out other titles in Deloitte’s Roadmap series, our comprehensive, easy-to-understand collection of accounting guides on selected topics of broad interest to the financial reporting community.
