12) Capital Stock | 12) Capital Stock The Company has one class of preferred stock of $1.00 par value, 5,000,000 shares authorized, of which none are issued. The preferred stock is non-voting. The Company has two classes of common stock with shares outstanding, Class A common shares and Class C common shares. Class C shares have 10 votes per share on all matters except for the election of one third of the directors who are elected solely by the Class A shares. Class C shares are convertible into Class A shares at any time on a one to one ratio. The decrease in treasury stock was the result of treasury stock being used to fund the company’s 401(k) Plans. Stockholders of both Class A and Class C common stock have received 5% stock dividends in the years 1990 through 2017, as authorized by the Company’s Board of Directors. The Company has Class B common stock of $1.00 par value, 5,000,000 shares authorized, of which none are issued. Class B shares are non-voting stock except to any proposed amendment to the Articles of Incorporation which would affect Class B common stock.
