Stockholders equity requirement for NASDAQ Capital Market listing, Description	On May 15, 2013, we received a letter indicating that the NASDAQ Listing Qualifications Panel (the "Panel") had determined to delist our common stock from The NASDAQ Stock Market LLC ("NASDAQ"), and suspend trading in our securities on NASDAQ effective with the open of business on Friday, May 17, 2013. The suspension is the result of our determination that we will be unable to evidence compliance with the $2.5 million stockholders' equity requirement for continued listing on The NASDAQ Capital Market, as set forth in NASDAQ Listing Rule 5550(b), by June 18, 2013, as required by the Panel's decision in this matter.
