Payments of interest and commitment fees, net of amounts capitalized, were $56.8 million and $46.3 million for the nine months ended September 30, 2015 and September 30, 2014, respectively. We capitalized interest of $11.9 million and $11.5 million during the nine months ended September 30, 2015 and September 30, 2014.

At September 30, 2015 and September 30, 2014, we had incurred liabilities for fixed and intangible asset additions totaling $50.2 million and $61.2 million, respectively, that had not been paid at the end of the third 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.

At September 30, 2015 we had incurred liabilities for other asset additions totaling $0.1 million, that had not been paid at the end of the third quarter and, therefore, were not included in the caption "Other, net" under Cash Flows from Investing Activities in the Unaudited Condensed Consolidated Statements of Cash Flows.

During the three months ended September 30, 2015, as a result of the Enterprise acquisition, we acquired the 50% ownership interest in each of CHOPS and SEKCO as previously held by Enterprise, resulting in 100% ownership interest by us in each of these subsidiaries. As a result, we recorded a one time $335 million non-cash gain from the step up in basis in our historical 50% ownership interest in each of CHOPS and SEKCO to fair value (resulting from the fair value assigned to the 50% ownership interest in each of CHOPS and SEKCO that we acquired from Enterprise, as derived from the preliminary purchase price allocation). This also results in the consolidation of CHOPS and SEKCO by us, resulting in the inclusion of the operating assets and liabilities on our Unaudited Condensed Consolidated Balance Sheet. As 50% of the operating assets and liabilities of CHOPS and SEKCO were based on our historical interest with no cash impact, these amounts relating to our historical interest were not included in net changes in components of operating assets and liabilities in the Unaudited Condensed Consolidated Statements of Cash Flows.
