Form 10-K for the Fiscal Year Ended December 31, 2022 Business Estimated Proved Reserves, page 17 1. We note the reconciliation of the changes in proved undeveloped reserves includes a line item entry of 46.4 MMBoe for Extensions and Discoveries that combines additions of 53.8 MMBoe in new reserves with an offset to remove 7.4 MMBoe for reserves that were not developed or were no longer expected to be developed within five years of their initial bookings as a result of changes in development plans. We also note you include similar adjustments to the net quantities shown in the reconciliation of the changes in total proved reserves for Extensions and Discoveries on page F-40 for the years ending December 31, 2022 and 2021, respectively. We believe that changes associated with reclassifying reserves due to changes in a previously adopted development plan should be categorized as revisions and included in the reconciliation under line item Revisions of Prior Estimates.
