Dear Mr. Bjornholt:

       We have reviewed your October 4, 2018 response to our comment letter and
have the
following comments. In some of our comments, we may ask you to provide us with
information
so we may better understand your disclosure.

       Please respond to these comments within ten business days by providing
the requested
information or advise us as soon as possible when you will respond. If you do
not believe our
comments apply to your facts and circumstances, please tell us why in your
response.

      After reviewing your response to these comments, we may have additional
comments. Unless we note otherwise, our references to prior comments are to
comments in our
September 25, 2018 letter.

Form 8-K filed on November 7, 2018

Exhibit 99.1, page 11

1.    We note your response to prior comment 2. The use of the term "net sales"
within the title
      of your non-GAAP measure implies that it is derived from GAAP, when in
fact, it is not a
      GAAP measure. Please revise the title of your "non-GAAP net sales"
measure to more
      appropriately reflect the fact that this measure represents the sales of
your product by your
      distributors to end customers during the period.

2.       Further, non-GAAP measures that reflect the impact of changes in
distributor inventory
         levels substitute individually tailored revenue recognition and
measurement methods for
         those of GAAP and do not comply with the guidance in Question 100.04
of the
         Compliance and Disclosure Interpretations on Non-GAAP Financial
Measures. Please
         revise accordingly.
       You may contact Tara Harkins at (202) 551-3639 or Lynn Dicker, Senior
Accountant, at
(202) 551-3616 if you have any questions.
