EBITDA- Earnings Before Interest, Taxes, Depreciation/Amortization.
OR properly figured using FAS 142 is pretty darn close to EBITDA in industry so it's not totally archaic.
Problem with EBITDA is that it's often used as a figure for cash flow and it isn't. Without someone completely understanding the differences, it can get you in a world of trouble.
Operating cash flow is a better measure of how much cash a company is generating because it adds non-cash charges (depreciation and amortization) back to net income and includes the changes in working capital that also use/provide cash (such as changes in receivables, payables and inventories). These working capital factors are the key to determining how much cash a company is generating.
