Payments of interest and commitment fees were $69.8 million and $35.4 million for the three months ended March 31, 2022 and March 31, 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 2022. The first interest payment made on our 2027 Notes was in July 2021. We capitalized interest of $2.0 million and $0.7 million during the three months ended March 31, 2022 and March 31, 2021, respectively.

At March 31, 2022 and March 31, 2021, we had incurred liabilities for fixed and intangible asset additions totaling $45.0 million and $27.1 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 increase in this amount is principally due to the increase in capital expenditures associated with our GOP (Note 10) and certain of our offshore growth capital expenditures.
