Eletropaulo — In September 2017, Eletropaulo obtained shareholder approval for the transfer of Eletropaulo’s shares to Novo Mercado, which is a listing segment of the Brazilian stock exchange with the highest standards of corporate governance. Certain preferred shareholders who did not vote in favor of the share transfer to the Novo Mercado have withdrawal rights which allow the shareholder to receive a cash payment for tendering their shares to Eletropaulo over a 30-day withdrawal rights window that expired on October 30, 2017. Due to these withdrawal rights, these shares were probable of becoming redeemable as of September 30, 2017 and the corresponding non-controlling interest was reclassified to temporary equity. Colon — Our partner in Colon made capital contributions of $30 million and $106 million during the nine months ended September 30, 2017 and 2016, respectively. Any subsequent adjustments to allocate earnings and dividends to our partner, or measure the investment at fair value, will be classified as temporary equity each reporting period as it is probable that the shares will become redeemable. IPALCO — In March 2016, CDPQ exercised its final purchase option by investing $134 million in IPALCO. The company also recognized an increase to additional paid-in capital and a reduction to retained earnings of $84 million for the excess of the fair value of the shares over their book value. In June 2016, CDPQ contributed an additional $24 million to IPALCO. Any subsequent adjustments to allocate earnings and dividends to CDPQ will be classified as NCI within permanent equity as it is not probable that the shares will become redeemable.
