Stock-based Compensation

Stock-based Compensation

In connection with the cash dividend of approximately $145 million paid to the holders of the Company's common stock, as disclosed in Note 5, the Company made an adjustment to the exercise price of all stock options outstanding as of that date in accordance with the stock option agreements’ original terms and conditions related to anti-dilution. The dividend, $2.77 on a per share basis, reduced the exercise price of all outstanding options from $9.41 to $6.64 effective May 15, 2015.

The Company's Board of Directors adopted its 2015 Equity Incentive Plan (2015 Plan) which became effective upon the pricing of the Company's IPO. The 2015 Plan allows for the granting of stock options, stock appreciation rights, restricted stock awards, restricted stock units and other awards convertible into or otherwise based on shares of the Company's common stock. On June 25, 2015, in connection with the IPO, the Company granted 1,260,567 stock options, 136,441 stock appreciation rights, 266,313 restricted stock awards and 16,125 restricted stock units under the 2015 Plan. The stock options, valued using a closed form option pricing model, and stock appreciation rights granted vest in equal annual increments over four years. The restricted stock awards vest on the third anniversary of the date of grant and the restricted stock units vest two business days after the public disclosure in 2016 of the Company’s financial results for fiscal year 2015.

As a result of the Company's completion of its IPO, the Company recognized $4.6 million of stock-based compensation expense associated with performance-based awards previously granted under the Company's 2012 Equity Incentive Plan. This cumulative catch-up was recognized once satisfaction of the performance condition within the awards became probable. As the awards remain subject to a market condition, the performance-based awards remain unvested as of June 30, 2015. In addition, the Company also recognized $3.7 million of stock-based compensation expense during the second quarter of 2015 related to outstanding stock appreciation rights which are recorded at fair value.
