EBITDA usually also includes so-called Non-operating result, which is the result of other than normal operating activities. Non-operating result includes, for example, investment income or dividends, if such activity is not the core activity of the company.

EBITDA also does not contain interest and income taxes (as well as EBIT) and as such it enables good comparison between companies with different financing structure and different tax rates (i.e. companies in different countries).
In practice is almost exclusively used abbreviation EBITDA (not PBITDA).
