2.       For each non-GAAP financial measure you present, including each
related non-GAAP
         financial measure as a percentage of net revenue, please present the
most directly
         comparable GAAP measures with equal or greater prominence as required
by Item
         10(e)(1)(i)(A) of Regulation S-K.
3.       We note you present a non-GAAP financial measure you identify as
Contribution Margin.
         Please explain to us how and why you believe it is appropriate to
eliminate all general and
         administrative expenses, all research and development expenses, and
fixed costs included
         in sales and distribution expenses, which appear to include salaries
and office
         expenses, from a non-GAAP performance measure. It is not clear to us

Interpretations.
Results of Operations, page 52

4.       We note you attribute increases in net revenue to increased pricing,
growth in existing
         products, new product launches, and new products obtained through
acquisitions. Given
         the significant acquisitions you completed in 2020 and your intention
to continue to grow
         your business through acquisitions, please revise your disclosures to
separately quantify
         and discuss the impact growth in existing products, new product
launches, and new
         products obtained through acquisitions had on net revenue during each
period presented.

5.       Please tell us your consideration for disclosing and discussing
impairment testing for
         goodwill and intangible assets as a critical accounting policy,
including the following:
             The number of reporting units you have and how you allocate
goodwill to reporting
              units.
             The percentages by which estimated fair values exceed carrying
values as of the most
              recent impairment test date, especially to the extent any
reporting units or intangible
              assets are at risk of failing their impairment test, as well as
the key assumptions used
              and potential events and/or changes in circumstances that could
reasonably be
              expected to negatively affect the key assumptions.
             How historical negative operating margin results are considered in
your estimates and
              a sensitivity analysis for potential changes in operating margins
on your estimates.
         Please also tell us if any events during the interim periods triggered
an interim impairment
         test, in this regard we note the decline in your stock price and the
going concern
         disclosures included in your most recent quarterly filing. If an
interim impairment test was
         preformed, please tell us the results, if an interim test has not been
performed, please
         explain why.

required by Item 308 of

page, explanatory
         note, signature page and paragraphs 1, 2, 4 and 5 of the

you recorded in
              each acquisition represents a significant percentage of the
