| Stock Issued During Period, Reverse Stock Splits, Description | On October 30, 2017, the Board approved an amendment to the Company’s Articles of Incorporation to increase the number of shares of our common stock by 70,000 shares to 141,429 shares (the “Authorized Capital Amendment”), subject to the approval of such amendment by the stockholders. On December 21, 2017, a special meeting of the stockholders was convened (the “December Special Meeting”). In the definitive proxy statement dated November 24, 2017 filed by us with the SEC in respect of the December Special Meeting (the “November Proxy Statement”), the Board solicited the vote of the stockholders in favor of the Authorized Capital Amendment. The November Proxy Statement stated that broker non-votes in respect of the Authorized Capital Amendment would be counted as votes against the amendment. However, under relevant stock exchange rules, brokers had the discretionary authority to vote any shares held in their name on behalf of a beneficial owner (“Broker Shares”), and in respect of which the broker did not receive voting instruction from the beneficial owner, in favor of the Authorized Capital Amendment. As such, brokers voted approximately 17,628 Broker Shares, in respect of which the brokers had not received voting instructions from the beneficial owners of such shares, in favor of the Authorized Capital Amendment at the December Special Meeting. Accordingly, after taking into account such Broker Shares, the Authorized Capital Amendment was approved by the stockholders at the December Special Meeting. However, as disclosed in more detail under Item 3 in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, some stockholders of the Company have claimed that the disclosure in the November Proxy Statement in connection with the effect on the Authorized Capital Amendment of beneficial owners not providing voting instructions in respect of their Broker Shares was incorrect. Accordingly, stockholders have been asked to vote again on the Authorized Capital Amendment at our 2018 Annual Meeting of Shareholders. Further information about such vote was provided in the Company’s Proxy Statement relating to its 2018 Annual Meeting of Shareholders, which was filed with the SEC on April 19, 2018. | ||||||||
