Disclosure of Compensation Related Costs, Share-based Payments [Abstract] |
Share-based compensation | Share-based compensation Under the 2010 Equity and Incentive Plan, as amended, HEI can issue shares of common stock as incentive compensation to selected employees in the form of stock options, stock appreciation rights (SARs), restricted shares, restricted stock units, performance shares and other share-based and cash-based awards. The 2010 Equity and Incentive Plan (original EIP) was amended and restated effective March 1, 2014 (EIP) and an additional 1.5 million shares was added to the shares available for issuance under these programs. As of March 31, 2016, approximately 3.4 million shares remained available for future issuance under the terms of the EIP, assuming recycling of shares withheld to satisfy minimum statutory tax liabilities relating to EIP awards, including an estimated 0.4 million shares that could be issued upon the vesting of outstanding restricted stock units and the achievement of performance goals for awards outstanding under long-term incentive plans (assuming that such performance goals are achieved at maximum levels). Under the 2011 Nonemployee Director Stock Plan (2011 Director Plan), HEI can issue shares of common stock as compensation to nonemployee directors of HEI, Hawaiian Electric and ASB. As of March 31, 2016, there were 141,044 shares remaining available for future issuance under the 2011 Director Plan. Share-based compensation expense and the related income tax benefit were as follows:

Stock awards. In the second quarter of each year, HEI grants shares to nonemployee directors of HEI, Hawaiian Electric and ASB under the 2011 Director Plan. The number of shares issued to each nonemployee director of HEI, Hawaiian Electric and ASB is determined based on the closing price of HEI Common Stock on the grant date. Stock appreciation rights. As of March 31, 2016 and December 31, 2015, there were no remaining SARs outstanding. SARs activity and statistics were as follows:

As of March 31, 2016, there was $6.1 million of total unrecognized compensation cost related to the nonvested restricted stock units. The cost is expected to be recognized over a weighted-average period of 3.0 years. For the first three months of 2016 and 2015, total restricted stock units that vested and related dividends had a fair value of $2.5 million and $3.0 million, respectively, and the related tax benefits were $0.9 million and $1.0 million, respectively. Long-term incentive plan payable in stock. The 2014-2016 long-term incentive plan (LTIP) provides for performance awards under the original EIP of shares of HEI common stock based on the satisfaction of performance goals considered to be a market condition and service conditions. The number of shares of HEI common stock that may be awarded is fixed on the date the grants are made subject to the achievement of specified performance levels. The potential payout varies from 0% to 200% of the number of target shares depending on achievement of the goals. The LTIP performance goals for the LTIP period includes awards with a market goal based on total return to shareholders (TRS) of HEI stock as a percentile to the Edison Electric Institute Index over the three-year period. In addition, the 2014-2016 LTIP has performance goals related to levels of HEI consolidated return on average common equity (ROACE), Hawaiian Electric consolidated ROACE and ASB net income — all based on the three-year averages, and ASB return on assets relative to performance peers. The 2015-2017 and the 2016-2018 LTIP provide for performance awards payable in cash, and thus, are not included in the tables below. LTIP linked to TRS. Information about HEI’s LTIP grants linked to TRS was as follows:
|  | Three months ended March 31
|  | 2016 |  | 2015
|  | Shares |  | (1) |  | Shares |  | (1)
Outstanding, beginning of period |  | 162,500 |  |  | $ | 27.66 |  |  | 257,956 |  |  | $ | 28.45 |

(1) | Weighted-average grant-date fair value per share determined using a Monte Carlo simulation model.
The grant date fair values of the shares were determined using a Monte Carlo simulation model utilizing actual information for the common shares of HEI and its peers for the period from the beginning of the performance period to the grant date and estimated future stock volatility and dividends of HEI and its peers over the remaining three-year performance period. The expected stock volatility assumptions for HEI and its peer group were based on the three-year historic stock volatility, and the annual dividend yield assumptions were based on dividend yields calculated on the basis of daily stock prices over the same three-year historical period. For the three months ended March 31, 2016 and 2015, there were no vested LTIP awards linked to TRS. For the three months ended March 31, 2016, all of the shares vested (which were granted at target level based on the satisfaction of TRS performance) for the 2013-2015 LTIP lapsed. As of March 31, 2016, there was $0.4 million of total unrecognized compensation cost related to the nonvested performance awards payable in shares linked to TRS. The cost is expected to be recognized over a weighted-average period of 0.8 years. LTIP awards linked to other performance conditions. Information about HEI’s LTIP awards payable in shares linked to other performance conditions was as follows:
|  | Three months ended March 31
|  | 2016 |  | 2015
