16. MAJOR SUPPLIERS

During the three-month period ended March 31, 2015 and 2014, the Company purchased 57.0% and 89.8% of its raw materials from its top five suppliers, respectively.  As of March 31, 2015 and 2014, amounts due to those suppliers included in accounts payable were $5,698,079 and $3,988,704, respectively. This concentration makes the Company vulnerable to a near-term severe impact, should the relationships be terminated.
