There are 2 branches of a company Batra Shoes Ltd. One is in Delhi & the other is in Mumbai. The accountant of the branch in Delhi uses LIFO method for valuation of inventory of shoes while the accountant of the branch in Mumbai uses FIFO method for valuation of inventory. When the accounts of the 2 branches are consolidated, this fact is ignored. Is it correct? If Not, which accounting convention is violated by this.
