Shareholders' equity |
7 · Shareholders’ equity
Reserved shares. As of December 31, 2017, HEI had reserved a total of 12,158,460 shares of common stock for future issuance under the HEI Dividend Reinvestment and Stock Purchase Plan (DRIP), the Hawaiian Electric Industries Retirement Savings Plan (HEIRSP), the HEI 2011 Nonemployee Director Stock Plan, the ASB 401(k) Plan and the 2010 Executive Incentive Plan. Equity forward transaction. On March 19, 2013, HEI entered into an equity forward transaction in connection with a public offering on that date for 6.1 million shares of HEI common stock at $26.75 per share. On March 20, 2015, HEI settled the remaining 4.7 million shares under the equity forward for proceeds of $104.5 million (net of the underwriting discount of $4.7 million), which funds were used for the reduction of debt and for general corporate purposes. The proceeds were recorded in equity at the time of settlement. Prior to their settlement, the shares remaining under the equity forward transactions were reflected in HEI’s diluted EPS calculations using the treasury stock method. For 2015, the equity forward transactions did not have a material dilutive effect on HEI’s EPS. Accumulated other comprehensive income/(loss). Changes in the balances of each component of accumulated other comprehensive income/(loss) (AOCI) were as follows:
