Big bath
Big Bath in accounting is an earnings management technique whereby a one-time charge is taken against income in order to reduce assets, which results in lower expenses in the future. The write-off removes or reduces the asset from the financial books and results in lower net income for that year. The objective is to ‘take one big bath’ in a single year so future years will show increased net income.
