### Implications for Businesses
- **Financial Reporting**: Companies must align their financial reporting practices to accurately reflect adjusted financial statement income.
- **Tax Planning**: Businesses should reassess their tax strategies to account for potential CAMT liabilities.
- **Compliance**: Ensuring compliance with CAMT provisions is crucial to avoid penalties and interest.
### Actionable Steps
