Disclosure of Compensation Related Costs, Share-based Payments [Abstract] |
Stock Compensation | Stock Compensation In May 2006, the Company adopted the 2006 Equity Incentive Plan (2006 EIP), which was amended on May 9, 2007. In September 2015, the Company’s stockholders approved the 2015 Stock Incentive Plan (2015 SIP), which replaced the Company’s 2006 EIP. As with the 2006 EIP, the primary purpose of the 2015 SIP is to encourage ownership in the Company by key personnel, whose long-term service is considered essential to the Company’s continued success. The 2015 SIP reserves 1,275,000 shares of the Company’s common stock for issuance to employees, directors, consultants, independent contractors and advisors, plus any additional shares that are forfeited, or are otherwise terminated under the 2006 EIP. The maximum aggregate number of shares that may be issued to employees under the 2015 SIP through the exercise of incentive stock options is 750,000. The Company uses various types of stock-based compensation under the 2006 EIP, as amended, and the 2015 SIP, including time-based restricted stock units (RSUs), performance-based restricted stock units (PSUs), stock appreciation rights, and non-qualified stock options (NQSOs). Annual grants of RSUs (Annual RSUs) and PSUs (Annual PSUs) are available to key employees and certain executive officers, and long-term incentive plan (LTIP) awards are available to certain officers, including named executive officers. Annual Awards The Company elected to grant Annual RSUs and Annual PSUs under the 2015 SIP to key employees, including certain executive officers of the Company, which entitle the recipients to receive shares of the Company’s common stock upon vesting. The Annual RSUs are subject to time-based vesting criteria and vest in equal annual installments over three years following the date of grant. The vesting of Annual PSUs is subject to the achievement of pre-established Company performance criteria measured over the fiscal year during which they are granted, and to the extent the performance criteria has been met, vest in equal annual installments over three years thereafter. During the year ended March 31, 2019, the Company granted 31,320 Annual PSUs and 62,743 Annual RSUs at a weighted-average grant date fair value of $116.34 and $116.85 per share, respectively. As of March 31, 2019, the Company determined that the target performance criteria related to the year ended March 31, 2019 Annual PSUs were achieved. Subsequent to March 31, 2019 through May 17, 2019, the Company granted no additional Annual RSUs or Annual PSUs. Long-Term Incentive Plan Options During the year ended March 31, 2019, no LTIP NQSOs were granted. Previously, the Company approved the issuance of LTIP NQSOs under the 2015 SIP, including in November 2016 (2017 LTIP NQSOs) and June 2017 (2018 LTIP NQSOs), which were awarded to certain members of the Company’s management team. If the recipient provides continuous service, the LTIP NQSOs will vest after the Company achieves the target performance criteria by the date specified in the award. Each vested LTIP NQSO provides the recipient the right to purchase a specified number of shares of the Company’s common stock at a fixed exercise price per share based on the closing price of the common stock on the date of grant. The 2017 LTIP NQSOs vested on March 31, 2019 and the 2018 LTIP NQSOs will vest on March 31, 2020. Subsequent to March 31, 2019 through May 17, 2019, the Company granted no LTIP NQSOs. The Company measures stock compensation expense for LTIP NQSOs at the date of grant using the Black-Scholes option pricing model. The following table presents the weighted-average valuation assumptions used for the recognition of stock compensation expense for the LTIP NQSOs granted:
|  | 2018 LTIP NQSOs |  | 2017 LTIP NQSOs
Expected life (in years) |  | 4.90 |  |  | 5.94 |
Expected volatility |  | 38.73 | % |  | 41.80 | %
Risk free interest rate |  | 1.78 | % |  | 1.95 | %
Dividend yield |  | — | % |  | — | %
Weighted-average exercise price |  | $ | 69.29 |  |  | $ | 61.86 |
Weighted-average option value |  | $ | 25.03 |  |  | $ | 26.27 |
Long-Term Incentive Plan Awards 2019 LTIP PSUs. In September 2018, the Company approved LTIP awards under the 2015 SIP for the issuance of PSUs (2019 LTIP PSUs), which were awarded to certain members of the Company’s senior management team, including the Company’s named executive officers. The 2019 LTIP PSUs are subject to vesting based on service conditions over three years, as well as the Company meeting certain revenue and pre-tax income performance targets for the fiscal year ending March 31, 2021. To the extent financial performance is achieved above the threshold levels for each of these performance criteria, the number of PSUs that will vest will increase up to a maximum of 200% of the targeted amount for that award. No vesting of any portion of the 2019 LTIP PSUs will occur if the Company fails to achieve revenue and pre-tax income amounts equal to at least 90% of the threshold amounts for these criteria. Following the determination of the Company’s achievement with respect to the revenue and pre-tax income criteria for the measurement period, the vesting of the 2019 LTIP PSUs will be subject to adjustment based on the application of a relative total shareholder return (TSR) modifier. The amount of the adjustment will be determined based on a comparison of the Company’s TSR relative to the TSR of a pre-determined set of peer group companies for the 36-month performance period commencing on April 1, 2018 and ending on the vesting date. A Monte Carlo simulation model was used to determine the grant date fair value by simulating a range of possible future stock prices for the Company and each member of the peer group over the 36-month performance period. Under the new program, the Company granted awards at the target performance level of 41,793 2019 LTIP PSUs during the quarter ended September 30, 2018. The average grant date fair value of these 2019 LTIP PSUs was $120.24 per share. Based on the Company’s current long-range forecast, the Company has determined that the achievement of at least the target performance criteria of these awards continues to be probable. 2016 LTIP PSUs. In November 2015, the Company approved LTIP awards under the 2015 SIP for issuance of PSUs (2016 LTIP PSUs), which were awarded to certain members of the Company’s management team. The 2016 LTIP PSUs were subject to vesting based on certain performance criteria and service conditions over three years. To the extent financial performance was achieved above the minimum threshold performance criteria, the number of 2016 LTIP PSUs that would vest was subject to increase up to a maximum of 200% of the targeted amount for that award. No vesting of any portion of the 2016 LTIP PSUs would occur if the Company failed to achieve at least 90% of the minimum threshold performance criteria. If the Company achieved the performance criteria, vesting of the 2016 LTIP PSUs would be subject to adjustment based on the application of a total stockholder return (TSR) modifier. The amount of the adjustment would be determined based on a comparison of the Company’s TSR relative to the TSR of a pre-determined set of peer group companies for the 36-month performance period. Under this program, the Company granted awards that contained a maximum of approximately 308,000 2016 LTIP PSUs during the year ended March 31, 2016. The weighted-average grant date fair value of the 2016 LTIP PSUs was $50.05 per share. The Company did not believe the achievement of at least the minimum threshold performance criteria was probable, and accordingly, did not recognize stock compensation expense for these awards during the years ended March 31, 2018 and 2017. As of March 31, 2018, the Company did not meet the minimum threshold performance criteria, and the awards did not vest and were cancelled. 2015 LTIP PSUs. In September 2014, the Company approved LTIP awards under the 2006 EIP for issuance of PSUs (2015 LTIP PSUs), which were awarded to certain members of the Company’s management team. The 2015 LTIP PSUs were subject to vesting based on certain performance criteria and service conditions over three years. To the extent financial performance was achieved above the minimum threshold performance criteria, the number of 2015 LTIP PSUs that vested would increase up to the maximum number of units granted under the award. Under this program, the Company granted awards that contained a maximum of approximately 160,000 2015 LTIP PSUs during the year ended March 31, 2015. The weighted-average grant date fair value of the 2015 LTIP PSUs was $98.29 per share. As of March 31, 2017, the Company determined that achievement of the minimum threshold performance criteria was not probable, and accordingly, the Company recognized a net reversal of stock compensation expense of approximately $1,400. As of March 31, 2017, the Company did not meet the minimum threshold performance criteria, and the awards did not vest and were cancelled. 2007 LTIP SARs and 2007 LTIP PSUs. In May 2007, the Company approved LTIP awards under the 2006 EIP for issuance of SARs (2007 LTIP SARs) and PSUs (2007 LTIP PSUs), which were awarded to certain members of the Company’s management team. These awards were subject to vesting based on certain performance criteria and service conditions. Half of the 2007 LTIP SARs and 2007 LTIP PSUs granted were fully vested as of December 31, 2011; 80% of the other half of the awards vested on December 31, 2015, while the remaining 20% did not vest and were cancelled, since it was determined that the Company had not achieved the required performance criteria as of December 31, 2016. Accordingly, the Company recognized a net reversal of stock compensation expense of $2,400 during the year ended March 31, 2017. Grants to Directors Each of the Company’s nonemployee directors is entitled to receive common stock with a total value of $125 for annual service on the Board of Directors. The shares are issued in equal quarterly installments with the number of shares being determined using the rolling average of the closing price of the Company’s common stock during the last ten trading days leading up to, and including, the 15 th day of the last month of each quarterly period. Each of these shares is fully vested on the date of issuance.
