Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

The Company’s stock-based compensation program is a long-term retention program that is intended to attract and reward talented employees and align stockholder and employee interests. As of June 30, 2017, the Company had one stock-based compensation plan under which it was granting equity awards. The Company is currently granting stock-based awards from its Amended and Restated 2014 Equity Incentive Plan (the "2014 Plan"), which was approved at the Company's Annual Meeting of Stockholders on June 22, 2017. In connection with certain of the Company’s acquisitions, the Company has assumed certain plans from acquired companies. The Company’s Board of Directors has provided that no new awards will be granted under the Company’s acquired stock plans. Awards previously granted under the Company's superseded stock plans that are still outstanding typically expire between five and ten years from the date of grant and will continue to be subject to all the terms and conditions of such plans, as applicable. The Company’s superseded stock plans with outstanding awards include the Amended and Restated 2005 Equity Incentive Plan ("2005 Plan").

Under the terms of the 2014 Plan, the Company is authorized to grant incentive stock options (“ISOs”), non-qualified stock options (“NSOs”), non-vested stock, non-vested stock units, stock appreciation rights (“SARs”), and performance units and to make stock-based awards to full and part-time employees of the Company and its subsidiaries or affiliates, where legally eligible to participate, as well as to consultants and non-employee directors of the Company. SARs and ISOs are not currently being granted. Currently, the 2014 Plan provides for the issuance of 46,000,000 shares of common stock. In addition, shares of common stock underlying any awards granted under the Company’s 2014 Plan or the 2005 Plan that are forfeited, canceled or otherwise terminated (other than by exercise) are added to the shares of common stock available for issuance under the 2014 Plan. Under the 2014 Plan, NSOs must be granted at exercise prices no less than fair market value on the date of grant. Non-vested stock awards may be granted for such consideration in cash, other property or services, or a combination thereof, as determined by the Company’s Compensation Committee of its Board of Directors. Stock-based awards are generally exercisable or issuable upon vesting. The Company’s policy is to recognize compensation cost for awards with only service conditions and a graded vesting schedule on a straight-line basis over the requisite service period for the entire award. As of June 30, 2017, there were 30,340,575 shares of common stock reserved for issuance pursuant to the Company’s stock-based compensation plans including authorization under its 2014 Plan to grant stock-based awards covering 25,119,327 shares of common stock. In connection with the completion of the Spin-off, these awards were modified as described below.

Under the 2015 ESPP, all full-time and certain part-time employees of the Company are eligible to purchase common stock of the Company twice per year at the end of a six-month payment period (a “Payment Period”). During each Payment Period, eligible employees who so elect may authorize payroll deductions in an amount no less than 1% nor greater than 10% of his or her base pay for each payroll period in the Payment Period. At the end of each Payment Period, the accumulated deductions are used to purchase shares of common stock from the Company up to a maximum of 12,000 shares for any one employee during a Payment Period. Shares are purchased at a price equal to 85% of the fair market value of the Company's common stock, on either the first business day of the Payment Period or the last business day of the Payment Period, whichever is lower. Employees who, after exercising their rights to purchase shares of common stock in the 2015 ESPP, would own shares representing 5% or more of the voting power of the Company’s common stock, are ineligible to continue to participate under the 2015 ESPP. The 2015 ESPP provides for the issuance of a maximum of 16,000,000 shares of common stock. As of June 30, 2017, 974,830 shares have been issued under the 2015 ESPP. The Company recorded stock-based compensation costs related to its employee stock purchase plans of $1.9 million and $2.1 million for the three months ended June 30, 2017 and 2016, respectively, and it recorded $3.5 million and $4.4 million for the six months ended June 30, 2017 and 2016, respectively.

The Company used the Black-Scholes model to estimate the fair value of its Employee Stock Purchase Plan awards with the following weighted-average assumptions:



	Six Months Ended
	June 30, 2017		June 30, 2016
Expected volatility factor	0.29		0.41
Risk free interest rate	0.60	%	0.35	%
Expected dividend yield	0	%	0	%
Expected life (in years)	0.5		0.5

The Company determined the expected volatility factor by considering the implied volatility in six-month market-traded options of the Company's common stock based on third party volatility quotes. The Company's decision to use implied volatility was based upon the availability of actively traded options on the Company's common stock and its assessment that implied volatility is more representative of future stock price trends than historical volatility. The risk-free interest rate was based on a U.S. Treasury instrument whose term is consistent with the expected term of the stock options. The Company's expected dividend yield input was zero as it has not historically paid, nor expects in the future to pay, cash dividends on its common stock. The expected term is based on the term of the purchase period for grants made under the ESPP.

Modifications of Share-Based Awards

In connection with the completion of the Spin-off, the terms of the Company's existing stock-based compensation arrangements required adjustments to the number and exercise price of outstanding stock options, non-vested stock units, non-vested stock, performance units, and other share-based awards to preserve the intrinsic value of the awards immediately before and after the Spin-off. The outstanding awards continue to vest over the original vesting periods. Certain outstanding awards at the time of the Spin-off held by employees of the GoTo Business were forfeited at the time of the separation. The stock awards held as of January 31, 2017 were adjusted as follows:


•	The number of shares of common stock subject to each outstanding stock option was increased and the corresponding exercise price was decreased to maintain the intrinsic value of each outstanding stock option immediately before and after the Spin-off. There was no incremental expense related to this adjustment.


•	The number of shares of common stock underlying each outstanding non-vested stock unit and performance unit was increased to preserve the intrinsic value of such award immediately prior to the Spin-off.


•	The opening prices of the performance units granted in 2015 and 2016 were adjusted to reflect the value of the shares of LogMeIn stock distributed to the Company's shareholders as a result of the Spin-off. These adjustments resulted in $6.5 million in incremental compensation expense to be recognized over the remaining vesting life of the underlying awards.

Non-vested Stock Units

Market Performance and Service Condition Stock Units

In March 2017, the Company granted senior level employees non-vested stock unit awards representing, in the aggregate, 275,148 non-vested stock units that vest based on certain target performance and service conditions. The number of non-vested stock units underlying the award will be determined within sixty days of the three-year performance period ending December 31, 2019. The attainment level under the award will be based on the Company's relative total return to stockholders over the performance period compared to a pre-established custom index group. If the Company’s relative total return to stockholders is between the 41st percentile and the 80th percentile when compared to the index companies, the number of non-vested stock units earned will be based on interpolation. The maximum number of non-vested stock units that may vest pursuant to the awards is capped at 200% of the target number of non-vested stock units set forth in the award agreement and is earned if the Company's relative total return to stockholders when compared to the index companies is at or greater than the 80th percentile. If the Company’s total return to stockholders is negative, the number of non-vested stock units earned will be no more than 100% regardless of the Company’s relative total return to stockholders compared to the index companies. If the awardee is not employed by the Company at the end of the performance period, the extent to which the awardee will vest in the award, if at all, is dependent upon the timing and character of the termination as provided in the award agreement. Each non-vested stock unit, upon vesting, represents the right to receive one share of the Company's common stock.

In January 2016, the Company granted its former Chief Executive Officer 220,235 non-vested stock units that vest based on certain target performance conditions; and in March 2016, the Company granted senior level employees 234,816 non-vested stock units that vest based on certain target performance conditions. These awards were modified as described above as a result of the Spin-off. The attainment level under the awards will be based on the Company's compound annualized total return to stockholders over a three-year performance period, with 100% of such stock units earned if the Company achieves total shareholder return of 10% over the performance period. Further, if the Company achieves annualized total shareholder return of less than 10% during the performance period, the awardees may earn all or a portion of the target award, but not in excess of 100% of such stock units, depending upon the Company’s relative total shareholder return compared to companies listed in the S&P Computer Software Select Index. If the Company's compound annualized total shareholder return is 5% or above, the number of non-vested stock units earned will be based on interpolation, with the maximum number of non-vested stock units earned capped at 200% of the target number of non-vested stock units for a compound annualized total return to stockholders of 30% over a three-year performance period as set forth in the award agreement. Within sixty days following an interim measurement period of 18 months, the Compensation Committee will determine the number of restricted stock units that would be deemed earned based on performance to date, and up to 33% of the target award may be earned based on such performance; however, any stock units that are deemed earned will remain subject to continued service vesting until the end of the three-year performance period, or a change in control, if earlier. Within sixty days following the conclusion of the performance period, the Company’s Compensation Committee will determine the number of restricted stock units that would vest upon the final day of the performance period based on the Company’s performance during the period and in accordance with the terms of the award. On the vesting date, the greater of the full period restricted stock units, or the interim earned restricted stock units, will vest in one installment.

The market condition requirements are reflected in the grant date fair value of the award, and the compensation expense for the award will be recognized assuming that the requisite service is rendered regardless of whether the market conditions are achieved. The grant date fair value of the non-vested performance stock unit awards was determined through the use of a Monte Carlo simulation model, which utilized multiple input variables that determined the probability of satisfying the market condition requirements applicable to each award as follows:



	March 2017 Grant		March 2016 Grant		January 2016 Grant
Expected volatility factor	0.27-0.32		0.29 - 0.39		0.29 - 0.37
Risk free interest rate	1.48	%	0.91	%	1.10	%
Expected dividend yield	0	%	0	%	0	%

For the March 2017 grant, the range of expected volatilities utilized was based on the historical volatilities of the Company's common stock and the average of its peer group. The Company chose to use historical volatility to value these awards because historical stock prices were used to develop the correlation coefficients between the Company and its peer group in order to model the stock price movements. The volatilities used were calculated over the most recent 2.75 year period, which is commensurate with the awards' performance period at the date of grant. The risk free interest rate was based on the implied yield available on U.S. Treasury zero-coupon issues with remaining terms equivalent to the performance period. The Company does not intend to pay dividends on its common stock in the foreseeable future. Accordingly, the Company used a dividend yield of zero in its model. The estimated fair value of each award as of the date of grant was $104.05.

For the March 2016 and January 2016 grants, the range of expected volatilities utilized was based on the historical volatilities of the Company's common stock and the average of its peer group. The Company chose to use historical volatility to value these awards because historical stock prices were used to develop the correlation coefficients between the Company and its peer group in order to model the stock price movements. The volatilities used were calculated over a three year period, which is commensurate with the awards’ performance period at the date of grant. The risk free interest rate was based on the implied yield available on U.S. Treasury zero-coupon issues with remaining terms equivalent to the performance period. The Company does not intend to pay dividends on its common stock in the foreseeable future. Accordingly, the Company used a dividend yield of zero in its model. The estimated fair value of each award as of the date of grant was $66.18 for the March 2016 grant and $49.68 for the January 2016 grant.

Service Based Stock Units

The Company also awards senior level employees, certain other employees and new non-employee directors, non-vested stock units granted under the 2014 Plan that vest based on service. The majority of these non-vested stock unit awards generally vest 33.33% on each anniversary subsequent to the date of the award. The Company also assumes non-vested stock units in connection with certain of its acquisitions. The assumed awards have the same three year vesting schedule. Each non-vested stock unit, upon vesting, represents the right to receive one share of the Company’s common stock. In addition, the Company awards non-vested stock units to all of its continuing non-employee directors. These awards vest monthly in 12 equal installments based on service and, upon vesting, each stock unit represents the right to receive one share of the Company's common stock.

Unrecognized Compensation Related to Stock Units

As of June 30, 2017, the number of all non-vested stock units outstanding, including market performance and service condition awards and service-based awards, including service-based awards assumed in connection with acquisitions, were 5,152,745. As of June 30, 2017, there was $296.9 million of total unrecognized compensation cost related to non-vested stock units. The unrecognized cost is expected to be recognized over a weighted-average period of 2.26 years.

Non-vested Stock

During the six months ended June 30, 2016, the Company granted non-vested stock awards of 118,588 shares to its former Chief Executive Officer, with a vesting period of approximately three years from the date of grant, subject to the holder’s continued employment with the Company and accelerated vesting under certain circumstances. Non-vested stock is issued and outstanding upon grant; however, award holders are restricted from selling the shares until they vest. If the vesting conditions are not met, the award will be forfeited. Compensation expense is measured based on the closing market price of the Company’s common stock at the date of grant and is recognized on a straight-line basis over the vesting period. For the three and six months ended June 30, 2017, the Company recognized $0.7 million and $1.3 million, respectively, of stock-based compensation expense related to non-vested stock awards. At June 30, 2017, there was $4.0 million of total unrecognized compensation expense related to these awards, which is expected to be recognized during the third quarter of 2017.
