Payments of interest and commitment fees were $117.5 million and $114.6 million for the six months ended June 30, 2023 and June 30, 2022, respectively.

We capitalized interest of $18.3 million and $5.9 million during the six months ended June 30, 2023 and June 30, 2022, respectively.

At June 30, 2023 and June 30, 2022, we had incurred liabilities for fixed and intangible asset additions totaling $64.0 million and $35.5 million, respectively, that had not been paid at the end of the quarter. Therefore, these amounts were not included in the caption “Payments to acquire fixed and intangible assets” under Cash Flows from Investing Activities in the Unaudited Condensed Consolidated Statements of Cash Flows. The amounts as of June 30, 2023 primarily relate to the capital expenditures associated with our GOP (Note 11) and offshore growth capital projects.
