US GAAP Financial Reporting: ASC Codification and IFRS-to-GAAP Reconciliation – London, 26 Apr – 7 May 2027

Programme overview

Introduction:

Subsidiaries that keep local books under International Financial Reporting Standards but report upward to a parent applying US GAAP face recurring conversion errors: leases classified under the wrong model, impairment losses reversed where the Codification forbids it, credit loss allowances measured on the wrong horizon and deferred tax left unadjusted. This US GAAP Financial Reporting and IFRS Reconciliation course from Core Concept trains accountants, controllers and auditors to locate guidance in the Accounting Standards Codification, apply its major Topics and quantify every IFRS difference. Participants build an IFRS-to-US GAAP Reconciliation Pack for a case subsidiary.

Course Objectives:

• Navigate the Accounting Standards Codification by Area, Topic, Subtopic and Section to locate authoritative US GAAP guidance and document research conclusions
• Apply ASC 606 and ASC 842 to customer contracts and lessee arrangements, including the finance versus operating lease classification absent from IFRS 16
• Measure inventory, property and intangible assets and test long-lived assets and goodwill for impairment using the ASC 360 recoverability test and the ASC 350 reporting unit approach
• Estimate current expected credit losses under ASC 326 and assess variable interest entities and acquisitions under ASC 805 for consolidation
• Compute deferred tax balances under ASC 740 and share-based payment expense under ASC 718 for parent reporting packages
• Prepare a documented IFRS-to-US GAAP reconciliation with conversion journal entries, a difference register and review evidence

Target Audience:

• Accountants who prepare subsidiary reporting packages submitted to a parent that applies US GAAP
• Controllers responsible for the periodic IFRS-to-GAAP conversion of local statutory ledgers
• Group reporting staff who review and consolidate subsidiary GAAP submissions
• Internal and external auditors who test conversion adjustments and GAAP reporting packages
• Technical accounting specialists who draft position papers on Codification guidance
• Finance teams in entities that prepare both IFRS and US GAAP financial statements

Conclusion:

Reporting reliably to a US GAAP parent from IFRS books depends on knowing exactly where the Codification departs from IFRS and recording each departure consistently. Week one builds Codification research skills and applies revenue, lease, inventory, asset, impairment and intangible guidance at entity level. Week two adds credit losses, financial instruments, consolidation, business combinations, income taxes and share-based payment, then turns conversion into a controlled and measured process. The capstone produces a reconciliation pack for the next reporting cycle.
