what happened to DYL?, page-21

Reconstructed:The reconstruction flag 'RE' is applied from the day the security commences trading on a reconstructed basis and remains for 12 months.
A reconstruction may be a consolidation (reduction in the number of shares on issue) or a share split (increase in the number of shares on issue). So, for example, if there is a 3:1 consolidation then the number of shares are divided by three, i.e. there is now one share for every three (previous) shares. This type of change will usually result in the share price being increased threefold. Alternatively if there is a 4:1 split, there are now four shares for every one (previous) share, the share price is usually reduced accordingly i.e. divided by four in this case.
All orders are purged at the end of the trading day prior to the security being quoted on an RE basis. A RD status note is also applied to the reconstructed instrument during the period of deferred settlement trading.

Hope this helps in understanding Reconstruction
