Share-Based Compensation | 11. SHARE-BASED COMPENSATION Overview of Share-Based Compensation Plans The Company’s 2016 Incentive Compensation Plan (the “2016 Plan”) authorizes awards of stock options, stock appreciation rights, restricted stock, restricted stock units, deferred stock, performance units, annual incentive awards, and substitute awards, which generally may be settled in cash or shares of our common stock. Any shares of our common stock that are subject to awards of stock options or stock appreciation rights payable in shares will be counted as 1.0 share for each share issued for purposes of the aggregate share limit and any shares of our common stock that are subject to any other form of award payable in shares will be counted as 1.35 shares for each share issued for purposes of the aggregate share limit. As of March 31, 2020, there were approximately 1.1 million shares of common stock available for future share-based awards under the 2016 Plan, which is net of (i) 0.8 million shares issuable upon exercise of outstanding options and (ii) 3.0 million shares underlying restricted stock units, which will be settled in shares of our common stock if the vesting conditions are met and thus reduce the common stock available for future share-based awards under the 2016 Plan by the amount vested. These shares have been multiplied by the applicable factor under the 2016 Plan to determine the remaining shares available as of March 31, 2020. Additionally, as of March 31, 2020 under the Company’s previous 2008 Incentive Compensation Plan, there were approximately 1.5 million shares issuable upon exercise of outstanding options and 0.1 million shares underlying outstanding deferred stock units, which will be settled in shares of our common stock if the vesting conditions are met. This plan was replaced by the 2016 Plan effective May 24, 2016. The vesting of all types of equity awards (stock options, stock appreciation rights, restricted stock awards, restricted stock units and deferred stock units) is subject to possible acceleration in certain circumstances. Generally, if a plan participant terminates employment for any reason other than by death or disability during the vesting period, the right to unvested equity awards is forfeited. As of March 31, 2020, we estimate that compensation expense of approximately $30.0 million will be recognized over the next four years for all unvested share-based awards that have been granted to participants, including stock options and restricted stock units to be settled in shares of stock but excluding any estimates of forfeitures. This amount includes expenses associated with all outstanding performance-based restricted stock unit awards as the Company currently believes it is probable that the associated performance targets for each award will be achieved. Stock Options. The exercise price of stock options granted under each of the plans is equal to the fair market value of our common stock on the date of grant. Employee stock options generally become exercisable 25% per year over a four-year service period beginning on the date of grant and expire ten years from the date of grant. Non-employee directors’ stock options expire ten years from the date of grant and generally become 100% exercisable after the first anniversary of the grant date. Grants of stock options are generally only subject to the service conditions. Stock option activity during the quarter ended March 31, 2020 under all of our plans was as follows (options in thousands):
|  | Options |  |  | Weighted Average Exercise Price |
Outstanding as of December 31, 2019 |  |  | 2,438 |  |  | $ | 9.32 |

Exercisable as of March 31, 2020 |  |  | 2,096 |  |  | $ | 8.53 |
Restricted Stock Units to be Settled in Stock. Restricted stock units to be settled in shares of stock which are not “performance-based” generally vest 25% per year over a four-year service period. Restricted stock units which are “performance-based” are subject to performance or market conditions that, even if the requisite service period is met, may reduce the number of units of restricted stock that vest at the end of the requisite service period or result in all units being forfeited. The performance-based restricted stock units generally vest three years after the grant date. The following table summarizes information with respect to all outstanding restricted stock units to be settled in shares of stock under our plans during the quarter ended March 31, 2020 (units in thousands):
|  | Restricted Stock Units to be Settled in Shares of Stock |  |

Outstanding as of March 31, 2020 |  |  | 2,214 |  |  | $ | 16.82 |  |
Deferred Stock Units to be Settled in Stock. We granted deferred stock units to our non-employee directors. The deferred stock units are to be settled in shares of stock. Settlement of the deferred stock units and delivery of the underlying shares of stock to the plan participants does not occur until he or she ceases to provide services to the Company in the capacity of a director, employee or consultant. The following table summarizes information with respect to all deferred stock units during the quarter ended March 31, 2020 (units in thousands):
|  | Deferred Stock Units to be Settled in Shares |  |  | Weighted Average Grant-Date Fair Value Per Unit |

(1) | Includes vested but unreleased awards. These awards are included in total outstanding awards until they are released under the terms of the agreement.
Restricted Stock Units to be Settled in Cash. Restricted stock units to be settled in cash generally vest 25% per year over a four-year service period beginning on the date of grant. Cash-settled restricted stock units are recorded as liabilities as the expense is recognized and the fair value for these awards is determined at each period end date with changes in fair value recorded in our unaudited condensed consolidated statements of income and comprehensive income in the current period. Cash-settled restricted stock units are settled with a cash payment for each unit vested equal to the closing price on the vesting date. Cash-settled restricted stock units are not included in common shares reserved for issuance or available for issuance under the 2016 Plan. The following table summarizes information with respect to all cash-settled restricted stock units during the quarter ended March 31, 2020 (units in thousands):
