|Share-based Compensation Arrangement by Share-based Payment Award [Line Items]|
The Company’s general practice has been to make a single annual grant of share-based compensation in the first quarter to key employees and to make other employee grants only in connection with new employment or promotions. Forms of share-based compensation granted to employees by the Company include stock options, non-vested shares of common stock (“non-vested shares”), and performance shares. The Company also typically makes a single annual grant of non-vested shares to non-employee directors in conjunction with the annual election of non-employee directors to the Board of Directors. Share-based compensation is based on the grant date fair value of the instrument and is recognized ratably over the requisite service period, or vesting period. All share-based compensation expense is recognized in salaries, wages and employee benefits.
Employee Activity - Stock Options
Stock option grants to employees generally expire seven years from the grant date and typically vest ratably over a three-year period. The Company historically used the Black-Scholes option-pricing model to estimate the grant-date fair value of options granted. The Company did not make any stock option grants in the three months ended March 31, 2019.
The following tables summarize the Company’s employee stock option activity and related information:
Employee Activity - Non-vested Shares
Non-vested share grants to employees vest ratably over a three-year period. The non-vested shares’ fair values were estimated using closing market prices on the day of grant. The following tables summarize the Company’s employee non-vested share activity and related information:
Employee Activity - Performance Shares
The Company annually grants performance shares to key employees. Under the terms of the performance share agreements, following the end of a three-year performance period, the Company will issue to these employees a calculated number of common stock shares based on meeting certain performance targets. For shares granted during the three months ended March 31, 2019, 50% of the performance share issuances will be based on meeting earnings before interest, taxes, depreciation and amortization ("EBITDA") per share targets and the remaining 50% of the performance share issuances will be based on the three year performance of the Company’s total shareholder return ("TSR") as compared to the TSR of a selected peer group. All performance shares granted during the three months ended March 31, 2018 were based on achieving total shareholder return targets.
Depending upon the EBITDA per share targets met, 0% to 200% of the granted shares may ultimately be issued. For shares granted based on total shareholder return, 0% of the shares will be issued if the Company's total shareholder return outperforms 25% or less of the peer group, but 200% of the shares will be issued if the Company's total shareholder return performs better than 90% of the peer group.
The fair value of the performance shares granted based on meeting EBITDA per share targets were estimated using the closing market prices on the day of grant and the probability of meeting these targets as of the date of grant.
The fair value of the performance shares granted based on the three year performance of the Company’s total shareholder return was estimated using a Monte Carlo simulation. The weighted average assumptions used in the Monte Carlo estimate were as follows:

Non-employee Director Activity - Non-vested Shares
Grants of non-vested shares to non-employee directors vest ratably over the elected term to the Board of Directors, or approximately one year. The following tables summarize the Company’s non-employee non-vested share activity and related information:
