The switch over of Indian economy from production to knowledge based economy and the growth of software & IT, financial services, business outsourcing, media, healthcare, pharmaceutical industries etc. have focussed on the increasing investments in intangible assets and with this transformation non financial information has gained a lot of importance. Intangible assets such as intellectual property, brands, customer relationship and talent hold much more value than tangible'visible'assets such as capital, land, buildings, machinery etc. in a knowledge based economy.
