Map close and consolidation risks to provider technical accounting strengths
List judgment-heavy areas that drive consolidation adjustments such as revenue, leases, or other complex reporting positions. Prioritize PwC, Ernst & Young, or KPMG because their technical accounting and disclosure support are built around IFRS and US GAAP close, consolidation, and policy interpretation.
