Stock-Based Compensation and Incentive Plans |
(8) | STOCK-BASED COMPENSATION AND INCENTIVE PLANS
The company’s employee stock option, restricted stock awards, restricted stock units (that settle in Tidewater common stock), phantom stock, and cash-based performance unit plans, are long-term retention plans that are intended to attract, retain and provide incentives for talented employees, including officers and non-employee directors, and to align stockholder and employee interests. The company believes its stock-based compensation and incentive plans are critical to its operations and productivity. The employee stock option plans allow the company to grant, on a discretionary basis, both incentive and non-qualified stock options as well as restricted stock. The restricted stock and stock unit awards include performance shares. Under the company’s stock option and restricted stock plans, the Compensation Committee of the Board of Directors has the authority to grant stock options, restricted shares and restricted stock units of the company’s stock to officers and other key employees. Under the terms of the plans, stock options are granted with an exercise price equal to the stock’s closing fair market value on the date of grant. The number of common stock shares reserved for issuance under the plans and the number of shares available for future grants at March 31, are as follows:
|  | 2016 |  |  | 2015 |
Shares of common stock reserved for issuance under the plans |  |  | 2,257,963 |  |  |  | 2,580,880 |
Shares of common stock available for future grants |  |  | 480,839 |  |  |  | 871,674 |
Stock Option Plans The company has granted stock options to its directors and employees, including officers, under several different stock incentive plans. Generally, options granted vest annually over a three-year vesting period measured from the date of grant. Options not previously exercised expire at the earlier of either three months after termination of the grantee’s employment or ten years after the date of grant. Upon retirement, unvested stock options are forfeited. The retiree has two years post retirement to exercise vested options. All of the stock options are classified as equity awards. The company uses the Black-Scholes option-pricing model to determine the fair value of options granted and to calculate the share-based compensation expense. Stock options were granted in fiscal 2016 and 2015 but not during fiscal 2014. The fair value and assumptions used for the stock options issued during the years ended March 31, are as follows:
|  | 2016 |  |  | 2015 |
Weighted average fair value of stock options granted |  | $ | 3.34 |  |  | $ | 5.54 |
Risk-free interest rate |  |  | 1.62 | % |  |  | 1.82 | %

As of March 31, 2016, total unrecognized stock-option compensation costs amounted to $2.8 million or $1.9 million net of tax. No stock option compensation costs were capitalized as part of the cost of an asset. Compensation costs for stock options that have not yet vested will be recognized as the underlying stock options vest over the appropriate future period. The level of unrecognized stock-option compensation will be affected by any future stock option grants and by the termination of any employee who has received stock options that are unvested as of the employee’s termination date. Restricted Stock Awards The company has granted restricted stock awards to key employees, including officers, under several different employee stock plans, which provides for the granting of restricted stock and/or performance awards to officers and key employees. The company awards both time-based and performance-based shares of restricted stock awards. The restrictions on the time-based restricted stock awards lapse generally over a four year period and require no goals to be achieved other than the passage of time and continued employment. The restrictions on the performance-based restricted stock award lapse if the company meets specific targets. During the restricted period, the restricted shares may not be transferred or encumbered, but the recipient has the right to vote the restricted shares and receive dividends on the time-based restricted shares. Dividends are accrued on performance-based restricted shares and ultimately paid only if the performance criteria are achieved. All of the restricted stock awards are classified as equity awards in stockholders’ equity. The value of restricted stock awards is generally amortized on a straight-line basis to earnings over the respective vesting periods and is net of forfeitures. The following table sets forth a summary of restricted stock award activity of the company for fiscal 2016, 2015 and 2014:
|  | Weighted-average Grant-Date Fair Value |  |  | Time Based Shares |  |  | Performance Based Shares |

All restricted stock awards have either fully vested or have been cancelled during fiscal 2016, as such there are no shares to lapse during fiscal 2017. Restricted stock award compensation expense and grant date fair value for the years ended March 31, is as follows:
(In thousands) |  | 2016 |  |  | 2015 |  |  | 2014 |
Grant date fair value of restricted stock vested |  | $ | 1,337 |  |  |  | 2,791 |  |  |  | 4,671 |
Restricted stock compensation expense |  |  | 472 |  |  |  | 2,855 |  |  |  | 4,633 |
As of March 31, 2016, total unrecognized restricted stock compensation costs amounted to $0 million, or $0 million net of tax. No restricted stock award compensation costs were capitalized as part of the costs of an asset. The amount of unrecognized restricted stock compensation will be affected by any future restricted stock grants and by the separation of an employee from the company who has received restricted stock grants that are unvested as of their separation date. There were no modifications to the restricted stock awards during fiscal 2016, 2015 and 2014. Restricted Stock Units The company has granted restricted stock units (RSUs) to key employees, including officers, under the company’s employee stock plan, which provides for the granting of restricted stock units to officers and key employees. The company awards time-based units, where each unit represents the right to receive, at the end of a vesting period, one unrestricted share of Tidewater common stock with no exercise price. The company also awards performance-based RSUs, where each unit represents the right to receive, at the end of a vesting period, up to two shares of Tidewater common stock with no exercise price. Vesting of the various performance-based restricted stock units is based on metrics such as a three year Total Shareholder Return (TSR) as measured against a three year TSR of a defined peer group and Return on Total Capital (ROTC) for the company over a three year performance period. The company uses assumptions underlying the Black-Scholes methodology to produce a Monte Carlo simulation model to value the TSR performance-based restricted stock units. The fair value of the ROTC performance-based RSUs and time-based RSUs is based on the market price of our common stock on the date of grant. The restrictions on the time-based RSUs lapse over a three year period from the date of the award and require no goals to be achieved other than the passage of time and continued employment. The restrictions on the performance-based restricted stock units lapse if the company meets specific targets as defined. During the restricted period, the RSUs may not be transferred or encumbered, but the recipient has the right to receive dividend equivalents on the restricted stock units, but there are no voting rights until the units vest. Dividend equivalents are accrued on performance-based restricted shares and ultimately paid only if the performance criteria are achieved. Restricted stock unit compensation costs are recognized on a straight-line basis over the vesting period, and are net of forfeitures. The following table sets forth a summary of restricted stock unit activity of the company for fiscal 2016, 2015, and 2014:

There were no modifications to the restricted stock units during fiscal 2016, 2015 and 2014. Phantom Stock Plan The company provides a Phantom Stock Plan to provide additional incentive compensation to key employees including officers of the company. The plan awards phantom stock units to participants who have the right to receive the value of a share of common stock in cash from the company. Participants have no voting or other rights as a shareholder with respect to any common stock as a result of participation in the phantom stock plan. The phantom shares generally have a three or four-year vesting period from the grant date of the award provided the employee remains employed by the company during the vesting period. Participants receive dividend equivalents at the same rate as dividends on the company’s common stock. The following table sets forth a summary of phantom stock activity of the company for fiscal 2016, 2015 and 2014:

The liability for this plan will be adjusted in the future until paid to the participant to reflect the value of the units at the respective quarter end Tidewater stock price. Cash-based Performance Plan The company provides a Cash-based Performance Plan as additional incentive compensation to officers of the company. The plan awards units equal to cash to participants where each unit represents the right to receive, at the end of a vesting period, up to two dollars. Vesting of the various cash-based performance units (CBU) is based on metrics such as a three year TSR as measured against a three year TSR of a defined peer group and ROTC for the company over a three year performance period. The company uses assumptions underlying the Black-Scholes methodology to produce a Monte Carlo simulation model to value the TSR cash-based performance units. The fair value of the ROTC CBUs is based on the market price of our common stock on the date of grant less dividends associated with the ROTC component. The CBUs do not receive dividend equivalents. The restrictions on the CBU’s lapse if the company meets specific targets as defined. Upon retirement, the Compensation Committee of the Board of Directors will take into consideration the accelerated vesting of the CBUs after certain age and service criteria are met. Cash-based performance unit compensation costs are recognized on a straight-line basis over the vesting period, and are net of forfeitures. The following table sets forth a summary of cash-based performance plan unit activity of the company for fiscal 2016 and 2015:

There were no modifications to the cash-based performance plan units during fiscal 2016 and 2015. Non-Employee Board of Directors Deferred Stock Unit Plan The company provides a Deferred Stock Unit Plan to its non-employee directors. The plan provides that each non-employee director is granted annually a number of stock units having an aggregate value of $115,000 beginning fiscal 2013 and $100,000 prior to fiscal 2013 on the date of grant. Dividend equivalents are paid on the stock units at the same rate as dividends on the company’s common stock and are re-invested as additional stock units based upon the fair market value of a share of company common stock on the date of payment of the dividend. A stock unit represents the right to receive from the company the equivalent value of one share of company’s common stock in cash. Payment of the value of the stock unit granted from inception of the plan to March 2013 shall be made upon the earlier of the date that is 15 days following the date the participant ceases to be a director for any reason or upon a change of control of the company. For these units, the participant can elect to receive five annual installments or a lump sum. Beginning with deferred stock units granted in fiscal 2014, participants have the additional option of electing a distribution made upon the earlier of the date that is 15 days following the date the participant ceases to be a director for any reason or upon a change of control of the company or distribution date commencing on an anniversary of the grant date, whichever is earlier. For the units granted in fiscal 2014 to fiscal 2016, the participant can elect to receive annual installments of two to ten years or a lump sum distribution. The following table sets forth a summary of deferred stock unit activity of the company for fiscal 2016, 2015 and 2014:
