Subsequent Events [Abstract] |  |
Description on notification received | On June 19, 2019, Nasdaq notified the Company that, although the Company had not regained compliance with the minimum $1.00 closing bid price per share requirement, Nasdaq has determined that the Company was eligible for an additional 180-day period, or until December 16, 2019, to regain compliance with the minimum bid price requirement. The second 180-day period relates exclusively to the $1.00 closing bid price deficiency, and the Company's common stock may be delisted from Nasdaq during the 180-day period for failure to maintain compliance with any other Nasdaq listing requirements for which the Company is currently on notice or which occurs during the 180-day period. | On December 19, 2018, the Company received a notification letter from The Nasdaq Stock Market LLC (Nasdaq) indicating that for 30 consecutive business days the Company's common stock did not maintain a minimum closing bid price of $1.00 per share as required by Nasdaq Listing Rule 5550(a)(2). Consistent with the Rule, Nasdaq initially provided the Company with a compliance period of 180 days, or until June 17, 2019, to regain compliance
