interest coverage ratio by accounting investment in associates, why no change?

what I meant is something got substracted from the sum of parent’s EBIT and sub’s EBIT.

But am not sure it is “equity earning” or “non-controlling interest”, because they happen to be same amount in that question.

Basically, I want to know how to calculate EBIT under acquisition method. Thanks.

OK. Then simply add operating revenue of sub to operating revenue of parent and do same for operating expenses. If sub is not under 100 % owned by parent, minority interest is not part of EBIT thus cannot be substracted from EBIT.
