   1.                                                   Your disclosure 
indicates that you continue to work to minimize the impact of supply
                                                        chain challenges. In 
future filings, please describe the actions you have taken, or expect
                                                        to take, to mitigate 
supply chain challenges. Additionally, we note that supply chain
                                                        challenges have 
adversely impacted your performance and your 2023 financial results. To
                                                        the extent there have 
been material impacts to your results of operations, revise future
                                                        results of operations 
discussions to quantify such impacts.

2.       Your disclosures on pages 39 and 64 identify several factors which may 
favorably or
         unfavorably impact your profit booking rates while your discussion 
regarding cost of sales
         merely cites changes in profit booking rates as the primary reason for 
changes in cost of
         sales. In future filings revise your discussion to identify the 
contributing factors
         driving the profit booking rate adjustments and the material factors 
contributing to the
         changes in the profit booking rate in the periods presented.
       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.
