A business investment loss, in the case of a share referred to in the first paragraph of section 232.1, is computed by subtracting from the loss determined in accordance with this Title the amount that must be added after 1977 by virtue of the application of paragraph b of section 535 in computing the adjusted cost base of the share or of any other share, in this paragraph referred to as a “replaced share”, for which the share or a replaced share was substituted or exchanged.
