The 2009 Plan authorizes 6,250,000 shares for issuance under the plan. A maximum of 3,125,000 shares under the 2009 Plan may be issued pursuant to stock awards, stock units and other stock-based awards , subject to adjustment as provided in the 2009 Plan .

Awards to employees and consultants under the 2009 Plan are made by a committee of the Board of Directors of the Company, except that with respect to awards to the Chief Executive Officer, the committee recommends those awards for approval by the non-employee directors of the Board of Directors. In the case of awards to non-employee directors, the Board of Directors of makes such awards . At March 31, 2016 , 3,989,744 shares underlying stock-based compensation awards were still available for grants under the 2009 Plan. No further grants may be made under the 2004 Plan. Performance Share Units – A performance share unit (“PSU”) represents the right to receive a share of the Company’s common stock if specified performance goals are met over the three - year performance period specified in the grant, subject to exceptions through the respective vesting period, generally three years. Each grantee is granted a target award of PSUs, and may earn between 0 % and 200 % of the target amount depending on the Company’s performance against the performance goals. The following table provides compensation costs for stock-based compensation related to PSUs : Three Months Ended March 31, 2016 2015 Stock-based compensation within operations and maintenance expenses $ 525 $ 1,078 Income tax benefit 209 439 The following table summarizes nonvested PSU transactions for the three months ended March 31, 2016 : Number Weighted of Average Share Units Fair Value Nonvested share units at December 31, 2015 424,858 $ 25.78 Granted 151,156 28.89 Performance criteria adjustment 26,047 25.62 Forfeited (5,900) 25.89 Share units vested 44,625 26.88 Share units issued (189,885) 23.25 Nonvested share units at March 31, 2016 450,901 $ 27.98 A portion of the fair value of PSUs was estimated at the grant date based on the probability of satisfying the market-based conditions using the Monte Carlo valuation method , which assesses probabilities of various outcomes of market conditions . The other portion of the fair value of the PSUs is based on the fair market value of the Company’s stock at the grant date, regardless of whether the market-based condition is satisfied. The per unit weighted-average fair value at the date of grant for PSUs granted during the three months ended March 31, 2016 and 2015 was $28.89 and $ 26.54 , respectively. The fair value of each PSU grant is amortized monthly into compensation expense on a straight-line basis over their respective vesting periods, generally 36 months. The accrual of compensation costs is based on our estimate of the final expected value of the award, and is adjusted as required for the portion based on the performance-based condition. The Company assumes that forfeitures will be minimal, and recognizes forfeitures as they occur, which results in a reduction in compensation expense. As the payout of the PSUs includes dividend equivalents, no separate dividend yield assumption is required in calculating the fair value of the PSUs. The recording of compensation expense for PSUs has no impact on net cash flows. Restricted Stock Units – A restricted stock unit (“RSU”) represents the right to receive a share of the Company’s common stock. RSUs are eligible to be earned at the end of a specified restricted period, generally three years, beginning on the date of grant. The Company assumes that forfeitures will be minimal, and recognizes forfeitures as they occur, which results in a reduction in compensation expense. As the payout of the RSUs includes dividend equivalents, no separate dividend yield assumption is required in calculating the fair value of the RSUs. The following table provides compensation costs for stock-based compensation related to RSUs : Three Months Ended March 31, 2016 2015 Stock-based compensation within operations and maintenance expenses $ 168 $ 263 Income tax benefit 69 109 The following table summarizes nonvested RSU transactions for the three months ended March 31, 2016 : Number Weighted of Average Stock Units Fair Value Nonvested stock units at December 31, 2015 88,353 $ 24.94 Granted 49,636 32.04 Stock units vested and issued (24,318) 23.37 Forfeited (1,500) 25.53 Nonvested stock units at March 31, 2016 112,171 $ 28.41 The per unit weighted-average fair value at the date of grant for RSUs granted during the three months ended March 31, 2016 and 2015 was $ 32.04 and $ 26.26 , respectively.
