Non-cash transactions
During the years ended December 31, 2014 and 2013, we recorded reductions of $85.2 million and $180.2 million, respectively, to noncontrolling interests in consolidated subsidiaries and offsetting increases to additional paid-in capital of $53.2 million and $112.9 million, respectively, (net of tax impacts of $31.9 million and $67.3 million, respectively). These non-cash entries represent the portion of proceeds in excess of historical cost which were attributed to Rose Rock's third-party unitholders related to Rose Rock's purchases of interests in SCPL (Note 4).
During the years ended December 31, 2014 and 2013, we issued 904,231 and 425,618 shares of Class A common stock, respectively, related to the exercise of warrants. These issuances resulted in the non-cash reclassifications for the years ended December 31, 2014 and 2013 of $73.0 million and $21.4 million, respectively, from other noncurrent liabilities to common stock and additional paid-in capital. Cash proceeds of $1.5 million and $0.2 million were received in connection with the warrant exercises for the years ended December 31, 2014 and 2013, respectively.
Other supplemental disclosures
We paid cash for interest totaling $36.7 million, $23.9 million and $8.0 million for the years ended December 31, 2014, 2013 and 2012, respectively.
We paid cash for income taxes (net of refunds received) in the amount of $23.5 million, $13.9 million and $11.4 million during the years ended December 31, 2014, 2013 and 2012, respectively.
We accrued $7.0 million, $10.1 million and $1.6 million at December 31, 2014, 2013 and 2012, respectively, for purchases of property, plant and equipment.
We sold common units of NGL Energy for proceeds of $88.8 million during the year ended December 31, 2014 (Note 5). At December 31, 2014, only $79.7 million of proceeds from the sales had been received and the remaining amount is a non-cash accrual at December 31, 2014.
