IPALCO — In March 2016, CDPQ exercised its remaining option by $134 million in IPALCO, which resulted in CDPQ’s combined direct and indirect interest in IPALCO of 30%. 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. 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.
