CAPITAL STOCK

Our common stock is 100% owned by active and retired employees, and there is no public trading market for our common stock. Since 1928, substantially all of the issued and outstanding shares of common stock have been held of record by voting trustees under successive voting trust agreements. Under applicable New York law, a voting trust may not have a term greater than ten years. Accordingly, a new Voting Trust Agreement was established effective March 3, 2017, which expires by its terms on March 1, 2027. At March 31, 2018, approximately 82% of the total shares of common stock was held in the voting trust. The participation of shareholders in the voting trust is voluntary at the time the voting trust is created, but is irrevocable during its term. Shareholders who elect not to participate in the voting trust hold their common stock as shareholders of record.
