On May 18 a new listing rules have been approved by Riga Stock Exchange that becomes effective on May 21 and according to that a new list structure will be introduced on Riga Stock Exchange. The new list structure will have two notable changes: modified admission and listing criteria on Baltic Main List and a new list - Baltic Secondary List - created by merging current Baltic I-List with Free List. Baltic Main List New admission and listing criteria will be applied to the Baltic Main List. Issuers on Baltic Main List will have to meet one of the following free float criteria: at least 25% of shares (the current criterion) or shares worth at least EUR 25 million must be held in public hands (free float shares). For the first time the compliance of issuers on the Baltic Main List with the new liquidity requirements will be evaluated in November 2007. Companies that will not be able to meet the requirements will be given 6 months transition period. In case of compliance after the period, companies will remain listed on the Baltic Main List. In case companies will not comply with the requirements after the transition period, they will be transferred to the Baltic Secondary List. New list - Baltic Secondary List Changes in the list structure will affect companies on the current Baltic I-List and Free Lists as both lists will be merged and companies on those lists will be traded together in the same list - Baltic Secondary List. This move will reduce current fragmentation of the lists in the Baltic market and will offer investors clearer list structure. After list rearrangement companies on Baltic Secondary List will have no free float requirements but will have the same information disclosure requirements that are applicable to I-List companies currently. After merger of the lists, current Free List companies will be included in calculation of OMX Baltic All-Share index, OMX Baltic Sector indexes and OMX Riga All-Share index. In addition to that those securities will be classified in accordance with Global Industry Classification Standard (GICS) improving their comparability with peer groups.
