Payments of interest and commitment fees were $189.2 million and $154.4 million for the nine months ended September 30, 2022 and September 30, 2021, respectively. The increase in interest payments during 2022 is primarily related to the timing of interest payments on our senior unsecured notes, specifically our 2027 Notes, as we made an interest payment in January and July during 2022. The first interest payment made on our 2027 Notes was in July 2021.

We capitalized interest of $11.2 million and $2.3 million during the nine months ended September 30, 2022 and September 30, 2021, respectively. The increase in capitalized interest is due to our growth capital expenditures associated with our GOP (Note 10) and our offshore growth capital projects.

At September 30, 2022 and September 30, 2021, we had incurred liabilities for fixed and intangible asset additions totaling $67.6 million and $44.9 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 September 30, 2022 primarily relate to the capital expenditures associated with our GOP (Note 10) and offshore growth capital projects.
