Shareholders' Equity | Shareholders’ Equity Preferred Stock. In conjunction with the acquisition of West Coast, the Company issued 8,782 shares of mandatorily convertible cumulative participating preferred stock, Series B. The Series B Preferred Stock is not subject to the operation of a sinking fund. The Series B Preferred Stock is not redeemable by the Company and is perpetual with no maturity. The holders of Series B Preferred Stock have no general voting rights. If the Company declares and pays a dividend to its common shareholders, it must declare and pay to its holders of Series B Preferred Stock, on the same date, a dividend in an amount per share of the Series B Preferred Stock that is intended to provide such holders dividends in the amount they would have received if shares of Series B Preferred Stock had been converted into Common Stock as of that date. The outstanding shares of Series B Preferred Stock are convertible into 102,363 shares of Company Common Stock. Warrants to Purchase Common Stock.
