STOCK-BASED COMPENSATION

The Company currently has one active stock plan, which became effective in 2017 upon the completion of the Combination. This plan replaces the HomeAdvisor 2013 Incentive plan, which governed equity awards prior to the Combination. The 2017 plan covers stock options, stock appreciation rights and RSU awards denominated in shares of ANGI Homeservices common stock, as well as provides for the future grant of these and other equity awards. The 2017 plan authorizes the Company to grant awards to its employees, officers, directors and consultants. At December 31, 2017, there are 25.8 million shares available for grant under the 2017 plan.

The 2017 plan has a stated term of ten years, and provides that the exercise price of stock options and stock appreciation rights granted will not be less than the market price of the Company's common stock on the grant date. The plan does not specify grant dates or vesting schedules for awards, as those determinations have been delegated to the Compensation Committee of ANGI Homeservices Board of Directors (the “Committee”). Each grant agreement reflects the grant date and vesting schedule for that particular grant as determined by the Committee. Stock options and stock appreciation rights granted subsequent to the Combination through December 31, 2017 generally vest in equal annual installments over a four-year period from the grant date. RSU awards granted subsequent to the Combination through December 31, 2017 generally cliff-vest three years from the grant date.

Stock-based compensation expense recognized in the consolidated and combined statement of operations includes expense related to: (i) the Company's stock options, stock appreciation rights and RSUs; (ii) equity instruments denominated in shares of its subsidiaries; and (iii) IAC denominated stock options and PSUs held by ANGI Homeservices employees. The amount of stock-based compensation expense recognized is net of estimated forfeitures, as the expense recorded is based on awards that are ultimately expected to vest. The forfeiture rate is estimated at the grant date based on historical experience and revised, if necessary, in subsequent periods if actual forfeitures differ from the estimated rate. At December 31, 2017, there is $188.4 million of unrecognized compensation cost, net of estimated forfeitures, related to all equity-based awards, which is expected to be recognized over a weighted average period of approximately 2.4 years.

The total income tax benefit recognized in the accompanying consolidated and combined statement of operations for the years ended December 31, 2017, 2016 and 2015 related to stock-based compensation is $71.1 million, $3.4 million and $3.0 million, respectively. The increase in total income tax benefit recognized during 2017 is due to the adoption of ASU 2019-06 and the recognition of excess tax benefits attributable to stock-based compensation included as a component of the current year provision for income taxes rather than recognized in equity.

The Company will recognize a corporate income tax deduction based on the intrinsic value of the stock options exercised in 2017, however, there will be some delay in the timing of the realization of the cash benefit of the income tax deduction because it will be dependent upon the amount and timing of future taxable income and the timing of estimated income tax payments. The income tax benefit to be realized on stock option deductions, including those net settled, for the year ended December 31, 2017, is $47.3 million. The income tax benefit realized on stock options deductions, including those net settled, for the years ended December 31, 2016 and 2015 are $8.8 million and $0.2 million, respectively.

The fair value of stock options and stock appreciation rights is estimated on the grant date using the Black-Scholes option pricing model. The Black-Scholes option pricing model incorporates various assumptions, including expected volatility and expected term. Prior to the Combination, expected stock price volatilities were estimated based on historical stock price volatilities of a group of peer companies. Subsequent to the Combination, expected stock price volatilities were estimated based on the average of IAC's historical volatility, as a result of the Company representing a large percentage of the overall value of IAC, and the historical stock price volatilities of the aforementioned group of peer companies. The risk-free interest rates are based on U.S. Treasuries with comparable terms as the awards, in effect at the grant date. Prior to the Combination, expected term was based upon the mid-point of the first and last windows for exercise. Subsequent to the Combination, expected term is based upon the historical exercise pattern of IAC's employees for comparable awards, a ten-year contractual life with vesting in four equal annual installments, because the Company does not have sufficient data to estimate an expected term for these awards. No dividends have been assumed. The following are the weighted average assumptions used in the Black-Scholes option pricing model:



	Years Ended December 31,
	2017		2016		2015
Expected volatility	50	%	44	%	48	%
Risk-free interest rate	2.0	%	0.8	%	1.2	%
Expected term	5.5 years		3.2 years		3.7 years
Dividend yield	—	%	—	%	—	%

Approximately 0.9 million stock options and stock appreciation rights were granted by the Company subsequent to the Combination through December 31, 2017. Approximately 4.7 million, 2.1 million and 2.4 million stock appreciation rights were granted by the Company for the period prior to the Combination in 2017, and for the years ended December 31, 2016 and 2015, respectively. The per share weighted average grant date fair value of stock options and stock appreciation rights granted by the Company subsequent to the Combination through December 31, 2017 is $4.30. The per share weighted average grant date fair value of stock appreciation rights granted by the Company for the period prior to the Combination in 2017, and for the years ended December 31, 2016 and 2015, are $8.24, $3.13 and $1.34, respectively.

In connection with the Combination, the previously issued HomeAdvisor (US) stock appreciation rights were converted into ANGI Homeservices' equity awards resulting in a modification charge of $217.7 million of which $93.4 million was recognized as stock-based compensation expense in the year ended December 31, 2017 and the remaining charge will be recognized over the vesting period of the modified awards.

During the second quarter of 2017, the Company modified certain HomeAdvisor (US) stock appreciation rights and recognized a modification charge of $6.6 million.

Cash received from stock option exercises for the period subsequent to the Combination through December 31, 2017 is $1.7 million. For periods prior to the Combination, no cash was received from the exercise of stock appreciation rights because they were net settled in shares of IAC’s common stock.

In connection with the Combination, previously issued stock appreciation rights that related to common stock of HomeAdvisor (US) were converted into stock appreciation rights that are settleable in Class A shares of ANGI Homeservices. IAC may require those awards to be settled in either shares of IAC common stock or in Class A shares of the Company's common stock and, to the extent shares of IAC common stock are issued in settlement, the Company will reimburse IAC for the cost of those shares by issuing to IAC additional Class A shares of the Company's common stock. Assuming all vested and unvested stock appreciation rights outstanding on December 31, 2017, which can only be exercised on a net basis, were exercised on that date, 16.4 million Class A shares of the Company's common stock would have been issued either (i) to IAC as reimbursement if the awards were settled in IAC shares or (ii) directly to award holders if IAC did not exercise its right to settle these awards in IAC shares. In either case, the Company would have remitted $171.3 million in cash in withholding taxes (assuming a 50% withholding rate) on behalf of the employees.

Restricted stock units

RSUs are awards in the form of phantom shares or units denominated in a hypothetical equivalent number of shares of ANGI Homeservices common stock and with the value of each RSU equal to the fair value of ANGI Homeservices common stock at the date of grant. Each RSU grant is subject to service-based vesting, where a specific period of continued employment must pass before an award vests. The expense is measured at the grant date as the fair value of ANGI Homeservices common stock and expensed as stock-based compensation over the vesting term.

Prior to the Combination, there were no RSUs outstanding. Unvested RSUs outstanding at December 31, 2017 and changes during the year ended December 31, 2017 is as follows:



	RSUs
	Number of Shares		Weighted Average Grant Date Fair Value
	(Shares in thousands)
Converted Angie's List RSUs in connection with the Combination	4,957		$	12.46
Granted	489		12.58
Vested	(1,574	)	12.46
Forfeited	(977	)	12.46
Unvested at December 31, 2017	2,895		$	12.48

The per share weighted average grant date fair value of RSUs granted during the year ended December 31, 2017 based on market prices of ANGI Homeservices’ common stock on the grant date was $12.58. The total fair value of RSUs that vested during the year ended December 31, 2017 was $19.2 million.

Equity instruments denominated in the shares of certain subsidiaries

ANGI Homeservices has granted stock appreciation rights and stock options denominated in the equity of its subsidiaries to employees and management of certain subsidiaries. These equity awards vest over a period of years, which is typically four years. The value of the stock appreciation rights and stock options is tied to the value of the common stock of these subsidiaries, which is determined by the Company using a variety of valuation techniques including a combination of market based and discounted cash flow valuation methodologies. Accordingly, these interests only have value to the extent the relevant business appreciates in value above the initial value utilized to determine the exercise price. These interests can have significant value in the event of significant appreciation. The interests are ultimately settled in IAC common stock or ANGI Homeservices common stock, at IAC's election, with fair value generally determined by negotiation or arbitration, at various dates through 2027. These equity awards are settled on a net basis, with the award holder entitled to receive a payment in shares equal to the intrinsic value of the award at exercise less an amount equal to the required cash tax withholding payment. The expense associated with these equity awards is initially measured at fair value, using the Black-Scholes option pricing model, at the grant date and is expensed as stock-based compensation over the vesting term.

The plans under which these awards are granted establish specific settlement dates or liquidity events for which the valuation of the relevant subsidiary is determined for purposes of settlement of the awards.

IAC denominated stock options

There were no IAC stock options granted by IAC under its equity incentive plans to employees of ANGI Homeservices during the year ended December 31, 2017. For each of the years ended December 31, 2016 and 2015, approximately 0.1 million IAC stock options were granted by IAC under its equity incentive plans to employees of ANGI Homeservices. Approximately 0.2 million IAC options remain outstanding to employees of ANGI Homeservices as of December 31, 2017. The fair value of each stock option award is estimated on the grant date using the Black-Scholes option-pricing model. IAC stock options are granted with exercise prices at least equal to the fair value on the date of grant, vest ratably in annual installments over a four-year period and expire ten years from the date of grant.

IAC denominated performance stock units ("PSUs")

There were 0.1 million IAC PSUs granted by IAC to employees of ANGI Homeservices during the year ended December 31, 2017. There were no IAC PSUs granted by IAC to employees of ANGI Homeservices during the years ended December 31, 2016 and 2015. PSUs are awards in the form of phantom shares or units, denominated in a hypothetical equivalent number of shares of IAC common stock and with the value of each PSU equal to the fair value of IAC common stock at the date of grant. Each PSU grant is subject to service-based vesting, where a specific period of continued employment must pass before an award vests and certain performance targets, set at the time of grant, must be achieved before an award vests.
