Consider the following companies from three different industries:

Iron & Steel industry: Tata Steel Ltd.

FMCG industry: Hindustan Unilever Ltd. (HUL)

Software industry: Infosys Ltd.

Collect the annual reports and financial statements of these three companies and analyse the cost structure of these companies for the financial year 2015-16. Also comment on the differences you get in the cost structure of these companies.

This will help to understand the differences in cost structure across industries. For this you need to look at the details of the notes to accounts of each and every cost element in the financial statements.
