New Accounting Pronouncements, Policy [Policy Text Block]	*Reverse Stock Split:* On August 15, 2019, the Company effected a reverse stock split of its outstanding shares of common stock at a ratio of one-for-twenty pursuant to a Certificate of Amendment to the Company’s Certificate of Incorporation filed with the Secretary of State of the State of New York. The reverse stock split was reflected on the Nasdaq Capital Market (“Nasdaq”) beginning with the opening of trading on August 15, 2019. The primary purpose of the reverse stock split, which was approved by the Company’s stockholders at the Company’s Annual Stockholders Meeting on June 27, 2019, was to enable the Company to regain compliance with the $1.00 minimum bid price requirement for continued listing on Nasdaq. Pursuant to the reverse stock split, every twenty shares of the Company’s issued and outstanding shares of common stock were automatically combined into one issued and outstanding share of common stock, without any change in the par value per share of the common stock. Unless otherwise indicated, all share and per share amounts of the common stock included in the accompanying interim condensed consolidated financial statements have been retrospectively adjusted to give effect to the reverse stock split for all periods presented, including reclassifying an amount equal to the reduction in par value to additional paid-in capital. Amounts of common stock resulting from the reverse stock split were rounded up to the nearest whole share. The reverse stock split affected all issued and outstanding shares of the Company’s common stock, and the respective numbers of shares of common stock underlying outstanding stock options, and the Company’s equity incentive plans were proportionately adjusted.
