If company A invests > 50% in company B, company B is a subsidiary of company A. If Co A invest >20% but less than 50% in company B, Company B is an associate company of company A.

So what if company A invests less than 20% in Company B's shares?

Q1 . How do we account for this type of investment in company A's books?

Q2. Does company A consolidate company B when preparing its consolidation account?

Q3. Which IFRS governs the answers for Q1 and Q2?

Thanks
