12.1 Introduction

This chapter provides income tax accounting and disclosure guidance related to noncontrolling interests, equity method investments (including specific exceptions in ASC 740 related to corporate joint ventures and changes in ownership of investees), qualifying investments accounted for by using the proportional amortization method, regulated entities, and distinguishing a change in estimate from a correction of an error. The book-versus-tax-differences chapter of this Roadmap (Chapter 3) provides helpful guidance on the respective definitions of inside and outside basis differences (see Section 3.3.1) and the recognition criteria for deferred taxes.
