The calculation starts with the Income Statement components:

• Non-cash expenses (e.g., Depreciation) are typically positive adjustments.
• Losses are generally positive adjustments (added back).

Balance Sheet Adjustments (Working Capital Changes)

These adjustments relate to changes in current assets and liabilities:

• Current Assets (e.g., Accounts Receivable, Inventory):
  • Increase in asset balance = Cash Outflow (–)
  • Decrease in asset balance = Cash Inflow (+)
• Current Liabilities (e.g., Accounts Payable):

  Note: Accounts Payable reverses the asset logic.

  • Increase in liability balance = Cash Inflow (+)
  • Decrease in liability
