On March 19, 2019, after the results of the 2019 Annual Meeting as set forth in Item 5.07 of this Current Report on Form 8-K became available, the Board approved a reverse stock split (the “Reverse Stock Split”) of the Company’s common stock at a ratio of 1-for-25, and a corresponding decrease in the number of authorized shares of the common stock. The Reverse Stock Split will become effective upon the date and time set forth in the stockholder-approved Certificate of Amendment to the Company’s Restated Certificate of Incorporation to be filed with the Secretary of State of the State of Delaware, which the Company expects will be on or about March 29, 2019. When the Reverse Stock Split becomes effective, 25 issued shares (including treasury shares) of Class A Common Stock, par value $0.01 per share (the “Class A Common Stock”), will be combined into one share of Class A Common Stock, and 25 issued shares (including treasury shares) of Class B Common Stock, par value $0.01 per share (the “Class B Common Stock”), will be combined into one share of Class B Common Stock. In addition, the number of authorized shares of the Class A Common Stock will be decreased from 400,000,000 to 16,000,000 and the number of authorized shares of the Class B Common Stock will be decreased from 60,000,000 to 2,400,000. The Reverse Stock Split will become effective as to both Class A Common Stock and Class B Common Stock at the same 1-for-25 ratio.

On March 19, 2019, after the results of the 2019 Annual Meeting as set forth in Item 5.07 of this Current Report on Form 8-K became available, the Board approved a reverse stock split (the “Reverse Stock Split”) of the Company’s common stock at a ratio of 1-for-25, and a corresponding decrease in the number of authorized shares of the common stock. The Reverse Stock Split will become effective upon the date and time set forth in the stockholder-approved Certificate of Amendment to the Company’s Restated Certificate of Incorporation to be filed with the Secretary of State of the State of Delaware, which the Company expects will be on or about March 29, 2019. When the Reverse Stock Split becomes effective, 25 issued shares (including treasury shares) of Class A Common Stock, par value $0.01 per share (the “Class A Common Stock”), will be combined into one share of Class A Common Stock, and 25 issued shares (including treasury shares) of Class B Common Stock, par value $0.01 per share (the “Class B Common Stock”), will be combined into one share of Class B Common Stock. In addition, the number of authorized shares of the Class A Common Stock will be decreased from 400,000,000 to 16,000,000 and the number of authorized shares of the Class B Common Stock will be decreased from 60,000,000 to 2,400,000. The Reverse Stock Split will become effective as to both Class A Common Stock and Class B Common Stock at the same 1-for-25 ratio.
