Dec. 31, 2015
Stock-Based Compensation | 13:S tock-B ased C ompensation CMS Energy and Consumers provide a PISP to officers, employees, and non‑employee directors based on their contributions to the successful management of the company. The PISP has a ten-year term, expiring in May 2024. In 2015, all awards were in the form of restricted stock or restricted stock units. The PISP also allows for unrestricted common stock, stock options, stock appreciation rights, phantom shares, performance units, and incentive options, none of which was granted in 2015, 2014, or 2013. Shares awarded or subject to stock options, phantom shares, or performance units may not exceed 6.5 million shares from June 2014 through May 2024, nor may such awards to any recipient exceed 500,000 shares in any calendar year. CMS Energy and Consumers may issue awards of up to 5,611,442 shares of common stock under the PISP as of December 31, 2015. Shares for which payment or exercise is in cash, as well as shares that expire, terminate, or are cancelled or forfeited, may be awarded or granted again under the PISP. All awards under the PISP vest fully upon death. Upon a change of control of CMS Energy or termination under an officer separation agreement, the awards will vest in accordance with specific officer agreements. If stated in the award, for restricted stock recipients who terminate employment due to retirement or disability, a pro-rata portion of the award will vest upon termination, with any market-based award also contingent upon the outcome of the market condition and any performance-based award contingent upon the outcome of the performance condition. The pro-rata portion is equal to the portion of the service period served between the award grant date and the employee’s termination date. The remaining portion of the awards will be forfeited. All awards for directors vest fully upon r etirement. Restricted shares may be forfeited if employment terminates for any other reason or if the minimum service requirements are not met, as described in the award document. Restricted Stock Awards: Restricted stock awards for employees under the PISP for 2015 and 2014 were in the form of performance-based, market-based, a nd time-lapse restricted stock. Prior to 2014, all grants were in the form of market-based and time-lapse restricted stock. Award recipients receive shares of CMS Energy common stock that have dividend and voting rights. In lieu of cash dividend payments, however, the dividends on performance-based and market-based restricted stock are paid in restricted shares equal to the value of the dividends. These additional restricted shares are subject to the same vesting conditions as the underlying restricted stock shares. Performance-based restricted stock vesting is contingent on meeting at least a 36‑month service requirement and a performance condition. The performance condition is based on CMS Energy’s EPS growth relative to a peer group over a three-year period. The awards granted in 2015 and 2014 require a 38‑month service period. Market-based restricted stock vesting is generally contingent on meeting a three-year service requirement and a market condition. The market condition is based on a comparison of CMS Energy’s total shareholder return with the median total shareholder return of a peer group over the same three-year period. Depending on the outcome of the performance condition or the market condition, a recipient may earn a total award ranging from zero to 200 percent of the initial grant. Time-lapse restricted stock generally vests after a service period of three years. Restricted Stock Units: In 2015, CMS Energy and Consumers granted restricted stock units to certain non‑employee directors who elected to defer their restricted stock awards. The restricted stock units generally vest after a service period of one year or, if earlier, at the next annual meeting. The restricted stock units will be distributed to the recipients as shares in accordance with the directors’ deferral agreements. Restricted stock units do not have voting rights, but do have dividend rights. In lieu of cash dividend payments, the dividends on restricted stock units are paid in additional units equal to the value of the dividends. These additional restricted stock units are subject to the same vesting and distribution conditions as the underlying restricted stock units. No restricted stock units vested or were forfeited during 2015. Presented in the following tables is the activity for restricted stock and restricted stock units under the 2009 and 2014 PISPs:

CMS Energy and Consumers charge the fair value of the restricted stock awards to expense over the required service period and charge the fair value of the restricted stock units to expense immediately. For performance-based awards, CMS Energy and Consumers estimate the number of shares expected to vest at the end of the performance period based on the probable achievement of the performance objective. Performance-based and market-based restricted stock awards have graded vesting features for retirement-eligible employees, and CMS Energy and Consumers recognize expense for those awards on a graded vesting schedule over the required service period. Expense for performance-based and market-based restricted stock awards for non‑retirement-eligible employees and time-lapse awards is recognized on a straight-line basis over the required service period. The fair value of performance-based and time-lapse restricted stock and restricted stock units is based on the price of CMS Energy’s common stock on the grant date. The fair value of market-based restricted stock awards is calculated on the grant date using a Monte Carlo simulation. CMS Energy and Consumers base expected volatilities on the historical volatility of the price of CMS Energy common stock. The risk-free rate for valuation of the market-based restricted stock awards was based on the three-year U.S. Treasury yield at the award grant date. Presented in the following table are the most important assumptions used to estimate the fair value of the market-based restricted stock awards:
Years Ended December 31 | 2015 |  | 2014 |  | 2013 |  |
Expected volatility |  | 14.1 | % |  | 15.6 | % |  | 17.4 | % |

Risk-free rate |  | 0.8 |  |  | 0.8 |  |  | 0.4 |  |
Presented in the following table is the weighted-average grant-date fair value of all awards under the PISP:

At December 31, 2015, $15 million of total unrecognized compensation cost was related to restricted stock for CMS Energy, including Consumers, and $15 million of total unrecognized compensation cost was related to restricted stock for Consumers. CMS Energy and Consumers expect to recognize this cost over a weighted-average period of 1.8 years. Since CMS Energy has utilized tax loss carryforwards, CMS Energy was unable to realize excess federal tax benefits upon vesting of restricted stock. Therefore, CMS Energy did not recognize the related excess federal tax benefits in equity. Since CMS Energy is not in a loss position for state tax purposes, CMS Energy recognized the related state tax benefits of $1 million in equity in 2015. As of December 31, 2015, CMS Energy ha d $33 million of unrealized excess federal tax benefits.
