Accounting Standards Update and Change in Accounting Principle RECENT ACCOUNTING GUIDANCE
Recently Adopted Accounting Guidance
In the first quarter of 2021, the Corporation adopted Accounting Standards Update 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes." The amendments simplify the accounting for income taxes by removing certain exceptions to the general principles of Topic 740, "Income Taxes" and improve consistent application by clarifying and amending existing guidance. The adoption of this guidance did not have a material impact on the consolidated financial statements.
