Payments of interest and commitment fees were $318.6 million, $276.2 million and $236.9 million during the years ended December 31, 2024, 2023 and 2022, respectively. We capitalized interest of $47.2 million, $43.2 million and $18.1 million during the years ended December 31, 2024, 2023 and 2022, respectively.

During the years ended December 31, 2024, 2023 and 2022, we paid income taxes of $1.4 million, $0.9 million and $1.0 million, respectively.

At December 31, 2024, 2023 and 2022, we had incurred liabilities for fixed and intangible asset additions totaling $56.3 million, $172.7 million and $93.5 million, respectively, which had not been paid at the end of the year. Therefore, these amounts were not included in the caption “Payments to acquire fixed and intangible assets” under Cash Flows from Investing Activities in the Consolidated Statements of Cash Flows. The decrease in this amount for the year ended December 31, 2024 compared to the previous two years is principally due to the completion of our Granger Optimization Project
