(16) SEGMENT REPORTING

At December 31, 2013, the Company has determined that it has three reporting segments comprised of the following subsidiaries, ZMI and ZBC, ZND and ZEU, and ZMS. This determination was made based on the nature of the products and services offered to customers or the nature of the function in the organization. The accounting policies for each of these segments are the same as those described in Note 2, and inter-segment transactions are eliminated. Net revenue was primarily generated from sales in the United States.
