Other supplemental disclosures
In connection with our acquisition of the noncontrolling interest in Rose Rock, as discussed in Note 2, we recorded a reduction to our deferred tax liabilities and offsetting increase to additional paid-in capital of $144.0 million associated with the transaction. This non-cash adjustment represents the deferred tax impact of the difference between the book value of the noncontrolling interest acquired and the tax basis which is stepped-up to the fair market value of the consideration which included the common shares issued and the assumption of liabilities associated with the noncontrolling interest.
We paid cash interest of $50.1 million and $40.5 million for the nine months ended September 30, 2016 and 2015, respectively.
We received cash refunds for income taxes, net of payments of $0.5 million and paid cash income taxes, net of refunds of $6.3 million for the nine months ended September 30, 2016 and 2015, respectively.
We incurred liabilities for construction work in process that had not been paid of $16.8 million and $7.3 million as of September 30, 2016 and 2015, respectively. Such amounts are not included in capital expenditures on the consolidated statements of cash flows.
We financed prepayments of insurance premiums of $4.0 million and $4.6 million for the nine months ended September 30, 2016 and 2015, respectively.
