Form 10-K for Fiscal Year Ended December 31, 2020 Management's Discussion and Analysis of Financial Condition and Results of Operations Results of Operations, page 46 1. We note your response to our prior comment 1. As previously noted, pursuant to Item 10(e)(1)(i)(B) of Regulation S-K, reconciliation of non-GAAP measures should be to the most directly comparable measure calculated and presented in accordance with GAAP. For the non-GAAP gross margin measure you present, the most directly comparable GAAP-basis measure appears to be a fully burdened gross margin that includes depreciation and amortization and any other relevant cost of revenue items. Please revise your disclosure accordingly. In this connection, the illustrative example included in your response appears to provide a reconciliation of your non-GAAP gross margin measure to GAAP-basis revenue. James A.
