Answer:
Earnings before interest & Tax (EBIT) is a common financial term used in business analysis and comparison. There are also many, many variations that are used, dependingon industry or company whimsy. Generally, they are done to provide values that are "in control" of management or the Co, as interest/taxes and some others are either not in the purview of regular management, or just accounting entries.
Another common one is EBITDA with adding Depreciation and Amortization ot EBIT.
The amounts are most simply derived by taking net earnings and adding back the values for each of those items. It is frequently shown as an informational sub total in accounting statements.
