NASDAQ OMX Group is in talks with executives of major market-making firms to resolve whether the exchange should repay trading firms for losses incurred by a software glitch, The Wall Street Journal reports. Trading in over 80 securities was halted in the first half hour of trading on April 25 as one of NASDAQ’s algorithms fed incorrect quotes to market makers.

Companies whose stock was affected by the ruling include Frederick’s of Hollywood Group, MGT Capital Investments, Roberts Realty Investors and SunLink Health Systems. Stock exchanges are cancelling all trades that were 30% above or below a benchmark price in the securities, while trades that occurred within 30% of the benchmark price were allowed to stand.
