Subsequent Events [Abstract] |
Subsequent Event | 17. Subsequent Event In October 2013, NASDAQ OMX announced the completion of initial review by The Market Regulation Department of FINRA of all claims submitted by qualifying members of The NASDAQ Stock Marke t for qualified losses arising directly from the system issues experienced with the Facebook IPO that occurred on May 18, 2012. Thereafter, NASDAQ OMX informed claimants that FINRA would be conducting additional analysis with regard to one category of claims. The announced total value of valid submitted claims wa s $41.6 million, but that amount may vary based on FINRA’s additional analysis. NASDAQ OMX will submit to the SEC a filing, for their review, that provides a report on the results of the analysis of FINRA. After the filing becomes effective, payment of valid claims will be made sixty (60) days following the effective date of the SEC filing.
