Capital gains computation for depreciable asset blocks: excess consideration is treated as short-term capital gains. Section 74 treats excess consideration on transfer(s) from a depreciable block - after deducting transfer expenditure, the block's opening written down value, and the actual cost of assets acquired in the tax year - as capital gains from transfer of short-term capital assets; if all assets in a block are transferred so the block ceases to exist, the cost of acquisition is the opening written down value plus actual cost of assets acquired in the tax year, and income from such transfers is deemed short-term capital gains.
