                                                        Please expand your
disclosure to explain with more specificity why and how.

   2.                                                   Your disclosure appears
to focus on how net cash used in operating activities was derived
                                                        for each period as
presented in the statement of cash flows. Pursuant to Item 303 of
                                                        Regulation S-K, your
discussion should be an analysis of why operating cash changed

         from period to period. That is, your analysis should be on the reasons
operating cash went
         from cash provided of $31.8 million in 2021 to cash used of $8.4
million in 2022. In
         performing your analysis, note that references to results, noncash
items and working
         capital items may not provide a sufficient basis to understand how
operating cash actually
         was affected between periods. For example, an increase in accounts
receivable due to an
         increased level of sales as you cited does not appear to directly
change cash. Refer to the
         introductory paragraph of section IV.B and paragraph B.1 of Release
No. 33-8350 for
         guidance. Please revise your disclosure as appropriate.
3.       We note your accounts receivable balance at June 30, 2022 is over 20%
of your net sales
         for the twelve months ended the same date, and that it was just over
15% of annual net
         sales at December 31, 2017. Please explain to us why the accounts
receivable balance has
         become a larger percentage of your net sales. It appears your accounts
receivable has
         been a consistent negative adjustment in arriving at your net cash
flows of operating
         activities on a three months basis in each quarter from the quarter
ended September 30,
         2020 through the quarter ended June 30, 2022. In connection with the
previous sentence
         and along with the first sentence, please explain to us how your days
of sales outstanding
         at December 31, 2021 and June 30, 2022 has decreased from the
respective corresponding
         period ended amount.
       In closing, we remind you that the company and its management are
responsible for the
accuracy and adequacy of their disclosures, notwithstanding any review,
comments, action or
absence of action by the staff.
