In May 2016, the Company adopted the 2016 Omnibus Incentive Compensation Plan (the “Omnibus Plan”) for the issuance of up to 2,000 common shares. As of December 31, 2022, approximately 696 shares remain available for grant under the Omnibus Plan. Stock Options Certain executives are eligible to receive grants of stock options. Employees may exercise the stock options at anytime after the grant is vested but no later than seven years after the date of grant. Stock options vest over a three-year period from the date of grant. For stock option awards, under the Plan, the exercise price is equal to the price of the Company’s common stock on the date of grant. Share-based compensation expense associated with these awards is amortized ratably over the vesting period. The Company estimated the fair value of the grants using the Black-Scholes option-pricing model. The weighted average grant-date fair value of the stock option awards granted under the Plan and the weighted average assumptions under the Black-Scholes option-pricing model were as follows for the years ended December 31, 2022, 2021 and 2020.

Weighted average grant-date fair value | $ | 28.91 |  |  | $ | 18.36 |  |  | $ | 14.79 |  |  |
Weighted average assumptions under Black-Scholes option model: |  |  |  |  |  |  |

As of December 31, 2022, the weighted average remaining contractual life of stock options outstanding was approximately three years and exercisable was approximately two years. The total fair value of stock options vested during 2022, 2021, 2020 was $855, $922, and $1,377, respectively. As of December 31, 2022, the total share-based compensation expense related to unvested stock options not yet recognized was $1,444, and the weighted average period over which it is expected to be recognized is approximately two years. The following table sets forth the exercise price range, number of shares, weighted average exercise price and remaining contractual lives by groups of similar price on a continuing operations basis as of December 31, 2022:

As of December 31, 2022, the total intrinsic value of outstanding and exercisable stock options was $14,642 and $13,390, respectively. The total intrinsic value of stock options exercised during 2022, 2021 and 2020 was $142, $2,137 and $1,568, respectively. Restricted Shares The Company’s primary long-term incentive plan is a restricted share award plan that entitles employees to receive a share of the Company’s common stock subject to vesting requirements based on continued employment. Shares granted under the restricted share award plan are restricted from sale or transfer until vesting, and the restrictions lapse in three equal installments beginning one year after the date of grant. Dividends are paid in cash on a current basis throughout the vesting period. Share-based compensation expense associated with these awards is amortized ratably over the requisite service period. All forfeitures are recognized as incurred. Restricted share transactions on a continuing operations basis for the year ended December 31, 2022 were as follows:
| Number of Shares |  | Weighted Average Grant Date Fair Value
Outstanding as of January 1 | 191 |  |  | $ | 69.84 |
Granted | 82 |  |  | 105.64 |
Vested | (92) |  |  | 67.41 |
Forfeited | (30) |  |  | 84.70 |
Outstanding as of December 31 | 151 |  |  | $ | 87.82 |
The weighted average grant-date fair value of the restricted shares granted under the Plan during the years ended December 31, 2022, 2021 and 2020 were $105.64, $75.35 and $65.88, respectively. The total fair value of restricted shares that vested during 2022, 2021 and 2020 was $9,804, $8,487, and $9,180, respectively. As of December 31, 2022, the total share-based compensation expense related to restricted shares not yet recognized was $7,729, and the weighted average period over which it is expected to be recognized is approximately two years. Performance Shares Certain executives and key employees are eligible to receive grants of performance awards. The performance share agreement provides for awards based on achieving certain financial targets, such as targets for earnings before interest, taxes, depreciation and amortization, and the Company’s total shareholder return as compared to the total shareholder return of a selected peer group, as determined by the Company’s Board of Directors. Performance targets are set at the beginning of each three-year measurement period. The share awards are earned over the vesting period, and the number of shares earned is determined based on the cumulative results for the measurement period. The performance agreement provides for employees to earn —% to 200% of the target awards depending on the actual performance achieved, with no shares earned if performance is below the established minimum target. Performance shares do not receive dividends until the shares are vested. Awards earned are paid in shares of common stock of the Company at the end of the vesting period. Share-based compensation expense associated with these awards is amortized ratably over the vesting period. Depending on the financial target, share-based compensation expense is determined based on the projected assessment of the level of performance that will be achieved. All forfeitures are recognized as incurred. The grant-date fair value of performance shares granted with a financial target based on the Company’s total shareholder return was estimated using a Monte Carlo simulation model. The weighted average grant-date fair value of performance awards granted under the Plan and the weighted average assumptions under the Monte Carlo simulation model were as follows for the years ended December 31, 2022, 2021 and 2020:
| Year Ended
| December 31, 2022 |  | December 31, 2021 |  | December 31, 2020
Weighted average grant-date fair value | $ | 127.29 |  |  | $ | 87.33 |  |  | $ | 69.15 |
Weighted average assumptions under the Monte Carlo simulation model: |  |  |  |  |
Expected stock price volatility | 35.5 | % |  | 34.5 | % |  | 23.5 | %
Weighted average risk-free interest rate | 1.6 | % |  | 0.2 | % |  | 1.4 | %
Performance award transactions for the year ended December 31, 2022 on a continuing operations basis were as follows assuming target levels of performance:
| Number of Shares |  | Weighted Average Grant Date Fair Value
Outstanding as of January 1 | 79 |  |  | $ | 75.61 |
Granted | 14 |  |  | 127.29 |
Earned | (7) |  |  | 63.40 |
Forfeited or unearned | (16) |  |  | 74.79 |
Outstanding as of December 31 | 70 |  |  | $ | 87.74 |
As of December 31, 2022, the total share-based compensation expense related to unearned performance awards not yet recognized, assuming the Company’s current projected assessment of the level of performance will be achieved, was $2,826, and the weighted average period over which it is expected to be recognized is approximately two years. The excess tax benefit realized for tax deductions in the United States related to the exercise of stock options, vesting of restricted stock and vesting of performance awards under the Pl an was $1,012, $911, and $2,340 for the years ended December 31, 2022, 2021 and 2020, respectively, on a continuing operations basis. Employee Stock Purchase Plan Under the 2005 Employee Stock Purchase Plan (the “ESPP”), the Company is authorized to issue up to a remaining 314 shares of common stock to employees. These shares may be issued at a price equal to 90% of the lesser of the market value on the first day or the last day of each six-month purchase period. Common stock purchases are paid for through periodic payroll deductions and/or up to two lump sum contributions. Employee stock purchase plan activity and related information was as follows on a continuing operations basis:

The restricted shares vest on the earlier of (a) the day immediately prior to the first annual shareholder meeting that occurs after the grant date or (b) one year after the grant date. Each director may elect to defer receipt of the common shares until the director departs from the Company’s Board of Directors.
