FinAnalysis: OCF operating Cash flow

OCF stands for operating cash flow, simply meaning cash flow provided by operating activities of a firm.

Definitions from other sites:
Wikipedia:
"Operating cash flow = Cash generated from operations less taxation and interest paid, investment income received and less dividends paid gives rise to operating cash flows per International Financial Reporting Standards"

Investopedia:
"The cash generated from the operations of a company, generally defined as revenues less all operating expenses, but calculated through a series of adjustments to net income.

It's arguably a better measure of a business's profits than earnings because a company can show positive net earnings (on the income statement) and still not be able to pay its debts. It's cash flow that pays the bills!"

Equation:
OCF = EBIT - taxes + depreciation

Why interest not deducted in here?
Interest is considered financing expenses, and most of the time it is already included when calculating WACC.
