15. CUSTOMER CONCENTRATION

During the three-month periods ended March 31, 2018 and 2017, the Company sold 88.8% and 36.4% of its products to its top five customers, respectively. As of March 31, 2018 and 2017, amounts due from these customers were $8,831,030 and $30,263,356, respectively. This concentration makes the Company vulnerable to a near-term severe impact, should the relationships be terminated.
