Shareholders' Equity: |
SHAREHOLDERS' EQUITY | Our Board of Directors (the “Board”) may, without further action by our shareholders, from time to time, direct the issuance of any authorized but unissued or unreserved shares of preferred stock in series and at the time of issuance, determine the rights, preferences and limitations of each series. The holders of such preferred stock may be entitled to receive a preference payment in the event of any liquidation, dissolution or winding-up by us before any payment is made to the holders of our common stock. Furthermore, the Board could issue preferred stock with voting and other rights that could adversely affect the voting power of the holders of our common stock. Reverse Stock Split On September 9, 2020, the Board approved a reverse stock split of our common stock and our Convertible Series A Preferred Stock, in each case, at a ratio of 1-for-8 and without any change to the respective par value thereof (the “Reverse Stock Split”), and, on September 10, 2020, we filed an Articles of Amendment to our Articles of Incorporation with the Department of State of the State of Florida to effect the Reverse Stock Split. The Reverse Stock Split became effective as of 5:00 p.m., Eastern time, on September 10, 2020 (the “Effective Time”). All per-share and share amounts have been retroactively restated in this Annual Report on Form 10-K for all periods presented to reflect the reverse stock split.
