I’m with you guys, that doesn’t really paint a picture for me either. I did some research, and apparently this is from IASB no. 1.88 and it is currently being debated on whether to change the way this is presented, particularly dealing with comprehensive income. Could see this changed in the future, anyway here is a breakdown for everyone.
a. Function refers to the primary activities in which an entity is engaged, such as selling a product or providing a service, cost of sales, research and development, marketing, and administrative activities.
b. Nature refers to the inputs (costs) required to accomplish those functional activities, such as costs related to people (labor and benefits), materials, energy, equipment (depreciation), and occupancy (rent).
Hope that explains it a little better. Back to the grind.
