Stockholders' Equity

Equity Incentive Plans

The Company uses various types of stock-based compensation under the 2006 Plan and 2015 SIP (as defined in the 2017 Annual Report), including time-based restricted stock units (RSUs), performance-based stock units (PSUs), stock appreciation rights (SARs) and non-qualified stock options (NQSOs). Annual grants of RSUs (Annual RSUs) and PSUs (Annual PSUs) are available to key personnel and certain executive officers, and long-term incentive plan (LTIP) PSUs or LTIP NQSOs are available to certain officers, including named executive officers.

Annual Awards

The Company has elected to grant Annual RSUs and Annual PSUs to key employees, including certain executive officers of the Company. These grants entitle the recipients to receive shares of common stock of the Company upon vesting. The vesting of Annual PSUs is subject to achievement of certain performance criteria measured over the fiscal year during which they are granted, while Annual RSUs are subject only to time-based vesting restrictions. Annual PSUs vest in equal one-third installments annually over three years after the performance criteria are achieved, and Annual RSUs vest in equal one-third installments annually over three years following the date of grant. During the three months ended June 30, 2017, the Company granted 54,090 Annual PSUs at a weighted-average grant date fair value of $68.44 per share and 123,837 Annual RSUs at a weighted-average grant date fair value of $67.84 per share. At June 30, 2017, the Company believes that the achievement of at least the threshold performance criteria of the fiscal year 2018 Annual PSUs is probable. The Company recorded stock compensation expense of $1,832 for the fiscal year 2018 Annual RSUs and Annual PSUs during the three months ended June 30, 2017. As of June 30, 2017, future unrecognized stock compensation expense for the fiscal year 2018 Annual RSUs and Annual PSUs granted to date, excluding estimated forfeitures, is $18,019.

Long-Term Incentive Awards

LTIP NQSOs

In November 2016, the Company approved the grant of LTIP NQSOs (2017 LTIP NQSOs) to the Company’s executive officers, which will vest on March 31, 2019 if the recipient provides continuous service through that date and the Company achieves the minimum threshold performance criteria. Each option grants the recipient the right to purchase a specified number of shares of the Company's common stock at a fixed exercise price per share. The Company measures stock compensation expense for LTIP NQSOs at the date of grant using the Black-Scholes option pricing model. This model estimates the fair value of the options based on a number of assumptions, such as expected option life, interest rates, the current fair market value and expected volatility, as well as dividend yield of the Company’s common stock. The fair value of the 2017 LTIP NQSOs granted during fiscal year 2017 less actual and estimated forfeitures as of June 30, 2017, was $4,619, and $497 was expensed during the three months ended June 30, 2017.

In June 2017, the Company approved the grant of LTIP NQSOs (2018 LTIP NQSOs) to the Company's executive officers, which will vest on March 31, 2020 if the recipient provides continuous service through that date and the Company achieves the minimum threshold performance criteria. The fair value of the 2018 LTIP NQSOs granted, less estimated forfeitures, was $4,489, and $79 was expensed during the three months ended June 30, 2017.

As of June 30, 2017, future unrecognized stock compensation expense for LTIP NQSOs granted to date, excluding estimated forfeitures, was $8,913.

The following table presents the weighted-average valuation assumptions used for the recognition of stock compensation expense for the 2018 LTIP NQSOs granted during the three months ended June 30, 2017:

Expected life (in years)	4.9
Expected volatility	38.73		%
Risk free interest rate	1.78		%
Dividend yield	—		%
Weighted-average exercise price	$	69.29
Weighted-average option value	$	25.03

Stock Repurchase Programs

In January 2015, the Company approved a new stock repurchase program to repurchase up to $200,000 of the Company's common stock in the open market or in privately-negotiated transactions, subject to market conditions, applicable legal requirements, and other factors. The program does not obligate the Company to acquire any particular amount of common stock and the program may be suspended at any time at the Company's discretion. Since inception through June 30, 2017, the Company has repurchased approximately 2,020,000 shares under the program for approximately $134,706, or an average price of $66.69 per share, leaving the remaining approved amount at approximately $65,294. During the three months ended June 30, 2017, the Company made no stock repurchases under this program.
