The Company recorded a $6.7 million and $4.0 million adjustment during the years ended December 31, 2017 and 2016, respectively, to the value of the Invenergy Wind redeemable non-controlling interest, reflecting the excess of the future redemption value over its carrying amount based on SEC guidance in ASC 480-10-S99-3A. Historically, the Company was accreting the redemption value of the Invenergy Wind redeemable non-controlling interest over the redemption period using the straight-line method and accretion adjustments were recorded against additional paid-in capital. As part of the Settlement Agreement, the Option Agreement between Terra LLC and Sun Edison LLC with respect to Invenergy Wind's remaining 9.9% interest in certain subsidiaries of the Company was rejected upon the consummation of the Merger with affiliates of Brookfield on October 16, 2017. As a result, the Company is no longer obligated to perform on its Option Agreement, and as of October 16, 2017, the Invenergy Wind non-controlling interest amount of $131.8 million was no longer considered redeemable and was reclassified to non-controlling interests as of such date. The redemption adjustments recorded in additional paid-in capital will remain in additional paid-in capital.
