Note: There figures are from the counter used for "parallel trading" of shares represented by old certificates, in parallel with trading on the main counter (or stock code) after a split, consolidation or change of board lot size. It's an archaic practice because we have had electronic settlement with a central counterparty by book-entry since 1993, so in reality no certificates change hands. It was due to be abolished on 3-Nov-08, but abolition has been delayed indefinitely. S=1 if suspended.
