The Company’s exposure to credit risk associated with non-payment will be affected principally by conditions or occurrences within Millennium Pharmaceuticals, Inc., a wholly-owned subsidiary of Takeda Pharmaceutical Company Ltd. (“Takeda”) and <span style="Background-color:#FFFFFF;color:#000000;">Vertex Pharmaceuticals Incorporated (“Vertex”)</span>. Takeda accounted for approximately 35% and 88% of total revenues for the years ended December 31, 2020 and December 31, 2019, respectively.
