6. Disposal of shares within four weeks of acquisition
The FIFO rules are modified in any case where shares of the same class are bought and sold within a period of four weeks. Where shares are sold within four weeks of acquisition the shares sold are identified with the shares acquired within that period. Furthermore, where a loss accrues on the disposal of shares and shares of the same class are acquired within a four week period, the loss is not available for offset against any other gains arising and instead is only available for set off against any gain that might arise on the subsequent disposal of the shares so acquired in the four week period - this provision does not apply where there is a gain on the disposal.
