The total value of the claims that market makers can recover after suffering losses due to Nasdaq OMX Group Inc.'s botched handling of Facebook Inc.'s initial public offering is $41.6 million, the exchange operator said.

The claims figure, which was calculated by Wall Street's industry-funded watchdog, the Financial Industry Regulatory Authority, falls short of the $62 million that Nasdaq had initially set aside to repay brokerages that lost money.

Nasdaq said the figure is lower in part because some claims did not qualify for compensation under its plan. The main reason for the lower figure, however, was because one firm opted to try to recover funds through arbitration.
