comment 2, you state that the calculated economic benefit to your
                                                        customers is based on
your internal estimates and feedback from your customers. Please
                                                        disclose the underlying
assumptions and limitations of your data. Discuss the number of

         Discuss how you calculated the internal estimates, the time period for
your projections,
         and whether the projections reflect the economic benefit to all
customers or are limited to
         your lighthouse customers.
3.       Please quantify the portion of your revenue attributable to lighthouse
customers. Confirm
         that the customers listed in the chart on page 3 are current
lighthouse customers.

on page 2 by
         disclosing the net loss for each period that you present in the chart.

5.       We have reviewed your response to prior comment 7. The RPO for Baker
Hughes
         appears to be important and material information necessary for an

not intend to report
         RPO for Baker Hughes and by customer in your future filings. We refer
you to Section
         III.B of SEC Interpretive Release 33-8350.

June 2020 annual
         commitments as modified disclosed on the same page. Please advise or
revise.
