CG50520 - Share identification rules: 1965 to 1982: share pooling

From 7 April 1965 to 5 April 1982 (31 March for companies) all acquisitions of shares of the same class in the same company were pooled. This means the cost of the shares was added together. The purchase of individual blocks of shares lost their identity in the pool. Instead all the shares in the pool were treated as though they were acquired at the same average cost. The pool was regarded as a single asset. Any disposal of less than all the shares in the pool was treated as a part disposal of that single asset.
