Starting September 27, 2010 the NASDAQ OMX Baltic Exchanges together with the NASDAQ OMX Nordic Exchanges will introduce Volatility Guards to reduce the likelihood of trading incidents. When the Volatility Guard is triggered, continuous trading is halted on the specific order book followed by an auction period with no auto matching. The auction period always ends with uncross. Right after uncross the order book moves into continuous trading again. The Volatility Guards come into two forms: • Dynamic Volatility Guard - utilized if an order deviates too much in percentage from the last sale price. For all Baltic shares 10% threshold applies. The length of the auction is 60 seconds. • Static Volatility Guard - utilized if an order deviates too much in percentage from the reference price, which is normally the day's opening price. For all Baltic shares 15% threshold applies. The length of the auction is 180 seconds. There will be no auction triggered if there is less than 240 seconds before the scheduled closing auction. NASDAQ OMX Baltic exchanges will continue to improve trading model and practices in order to maximize the quality of trading environment. Market Services Department +370 5 219 57 07
