Payments of interest and commitment fees were $158.2 million and $126.9 million for the nine months ended September 30, 2018 and September 30, 2017, respectively. We capitalized interest of $2.7 million and $13.8 million during the nine months ended September 30, 2018 and September 30, 2017. At September 30, 2018 and September 30, 2017, we had incurred liabilities for fixed and intangible asset additions totaling $16.6 million and $25.7 million, respectively, that had not been paid at the end of the quarter, and, therefore, 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. On August 7, 2018, we granted a third party a time-limited option to acquire certain of our non-core assets in the Powder River Basin in exchange for an option payment of $30 million. We have reflected our proceeds from this option payment in the net cash flows from investing activities section of the Unaudited Condensed Consolidated Statements of Cash Flows. Additionally, we reclassified the property, plant, and equipment related to these assets, in the amount of $255.5 million, as current assets held for sale on our Unaudited Consolidated Balance Sheet as of September 30, 2018.
