       Exhibit 99.1, page 8

   1.                                                   We note from your
response to our prior comment 3 that you will change your
                                                        presentation in future
filings to present your non-GAAP measures "without appearing to
                                                        be a full non-GAAP
income statement." However, we note that your presentation did not
                                                        change from your Q1
2020 results furnished on April 29, 2020 to your Q2 2020 results
                                                        furnished on July 30,
2020, after the date of our letter on July 9, 2020. In this regard,
                                                        please provide us with
your proposed disclosure in future Forms 6-K.
   2.                                                   We note your response
to our prior comment 4 that you will "discontinue the presentation
                                                        of FCI divestiture
adjustments in subsequent periods when for sequential or year-after-
                                                        year comparisons, past
periods no longer include FCI operating results and the gain from
                                                        divestiture." However,
we continue to believe that as the FCI divested operations did not

         meet the criteria for being presented as discontinued operations
pursuant to ASC 205-20,
         your non-GAAP measures appear to substitute individually tailored
recognition and
         measurement methods for those of GAAP. Therefore, as originally
stated, please revise
         your non-GAAP presentations to comply with Question 100.04 of the
Non-GAAP C&DIs
         by removing the FCI divestiture adjustments. Please be advised that
the revenue example
         discussed in Question 100.04 is only one example of a tailored
measure. Note that
         alternatively, you may adjust for just the gain from the divestiture,
given that it was a one-
         time, non-cash charge.
      You may contact Heather Clark at 202-551-3624 or Melissa Raminpour at
