Revenue from Contract with Customer [Text Block]

(

2

) REVENUES:

The Company operates in

one

business segment, which primarily focuses on the development and commercialization of innovative cyclodextrin-based products for the treatment of people with serious and life threatening rare diseases and medical conditions. The Company considers there to be revenue concentration risks for regions where net product revenues exceed

10%

of consolidated net product revenues. The concentration of the Company’s net product revenues within the regions below

may

have a material adverse effect on the Company’s revenues and results of operations if sales in the respective regions experience difficulties. The Company adopted the requirements of ASC

606

on

January 1, 2018

using the modified retrospective method. See Note

1

(h) – Revenue Recognition for additional discussion.
