| Stockholders' Equity, Reverse Stock Split | On June 8, 2018, the Company filed a Certificate of Amendment of its Certificate of Incorporation, as amended with the Secretary of State of Delaware effecting a one-for-ten (1:10) reverse stock split of the shares of the Company's common stock, either issued and outstanding or held by the Company as treasury stock, effective as of 4:10 p.m. (Eastern Time), June 8, 2018. The Company's common stock began trading on a reverse split adjusted basis on the Exchange when the market opened Monday, June 11, 2018. | On May 23, 2018, the Company's Board of Directors approved the implementation of a reverse stock split at a ratio of one-for-ten (1:10) shares of the Company's Common Stock. As a result of the reverse stock split, every ten (10) shares of the Company's Common Stock either issued and outstanding or held by the Company in its treasury immediately prior to the effective time was, automatically and without any action on the part of the respective holders thereof, combined and converted into one (1) share of the Company's common stock. No fractional shares were issued in connection with the reverse stock split. Stockholders who otherwise were entitled to receive a fractional share in connection with the reverse stock split instead were eligible to receive a cash payment, which was not material in the aggregate, instead of shares. | On April 23, 2018, the Company held a special meeting of its stockholders at which the stockholders approved a proposal to effect an amendment to the Company's certificate of incorporation, as amended, to implement a reverse stock split at a ratio to be determined by the Company's Board of Directors in a range not less than one-for-two (1:2) and not greater than one-for-ten (1:10). | |||||||||||||||||||||||||
