Big Bath Restructuring Abuse Taking massive one-time write-offs, restructuring charges, or asset impairments during an already poor period to clear the books for future artificial profitability. Allowance for Loan and Lease Losses / Bad Debt Manipulation Artificially depressing bad debt reserves, loan loss provisions, or warranty reserves to understate expenses and inflate net income. Deferred Cost Abuse and Prepaid Inflation Deferring current period customer acquisition, marketing, or contract costs as prepaid assets rather than recognizing them as expenses.
