Refund received						$ 962

[1] Noncash activity for the year ended December 31, 2022 primarily included approximately $500 million for a finance lease ROU asset and related liability recognized in connection with the completion of the DGD Port Arthur Plant described in Note 4.Noncash activity for the year ended December 31, 2020 primarily included approximately $800 million for a finance lease ROU asset and related liability recognized in connection with the terminaling agreement with MVP. Upon completion of construction of the MVP Terminal in the first quarter of 2020, we recognized a finance lease ROU asset and related liability of approximately $1.4 billion in connection with the terminaling agreement with MVP to utilize the MVP Terminal for an initial term of 12 years and renewal option periods. In the fourth quarter of 2020 in connection with our review of certain of our logistics investments, including MVP, we notified MVP that we would not renew the terminaling agreement after its initial noncancelable term. Consequently, we derecognized approximately $600 million of the finance lease liability and related ROU asset, which were noncash financing and investing activities, respectively.

[2] This amount includes a refund of $962 million that we received related to our U.S. federal income tax return for 2020.
