7. Customer and Supplier Concentration

Customer Concentrations

Three large wholesale drug distributors, AmerisourceBergen Corporation, or AmerisourceBergen, Cardinal Health, Inc., or Cardinal, and McKesson Corporation, or McKesson, are all distributors of the Company’s products, as well as suppliers of a broad range of health care products. Actavis had exclusive marketing rights of the Company’s enoxaparin product to the U.S. retail pharmacy market (see Note 16). The Company considers these four customers to be its major customers, as each individually, and these customers collectively, represented a significant percentage of the Company’s net revenue for the three months ended March 31, 2017 and 2016 and accounts receivable as of March 31, 2017 and December 31, 2016. The following table provides accounts receivable and net revenue information for these major customers:


	% of Total Accounts				% of Net
	Receivable				Revenue

The Agreement with Actavis was terminated in December 2016.

Supplier Concentrations

The Company depends on suppliers for raw materials, active pharmaceutical ingredients, and other components that are subject to stringent U.S. Food and Drug Administration, or FDA, requirements. Some of these materials may only be available from one or a limited number of sources. Establishing additional or replacement suppliers for these materials may take a substantial period of time, as suppliers must be approved by the FDA. Furthermore, a significant portion of raw materials may only be available from foreign sources. If the Company is unable to secure, on a timely basis, sufficient quantities of the materials it depends on to manufacture and market its products, it could have a materially adverse effect on the Company’s business, financial condition, and results of operations.
