Oslo Børs has reviewed the allocation of listed companies to liquidity categories based on trading in their shares over the last six months. The new allocations will come into effect from Friday 20 June 2008.
The rebalancing has caused three changes in the OBX category. Aker Yards, Norske Skog and Tomra will be replaced by Aker, Sevan Marine and Schibsted.
The number of companies in the OB Match category is reduced from 140 to 130, which is a larger change compared to the review in December 2007. The OB Standard category has increased by 10 companies to 61. The OB Primary Capital Certificates category is unchanged at 22 saving banks.
Only one company was listed at Oslo Børs in the period 1 December to 31 May. Therefor it is only one company in the OB New category (Hafslund Infratek).
The number of companies in the different Oslo Børs liquidity categories (figures for the previous period in brackets):
OBX 25 (25)
OB Match 130 (140)
OB Standard 61 (51)
OB New 1 (6)
OB Primary Capital Certificates 22 (22)
The OBX category is normally made up of the 25 most liquid shares on Oslo Børs. Shares with a minimum of 10 trades per day on average qualify for inclusion in the OB Match category. The OB Match category also includes companies that have entered into liquidity provider arrangements for their shares. As of June 20, 39 companies has such arrangements, which is unchanged from the last review. Shares with fewer than 10 trades per day on average are allocated to the OB Standard category. Savings banks with issues of listed primary capital certificates make up a separate category, while shares that have only a short history of listing (listed for less that two months) are included in the OB New category.
