(4) Stock-Based Compensation
Liberty grants, to certain of its directors, employees and employees of its subsidiaries, restricted stock, restricted stock units (“RSUs”) and stock options to purchase shares of its common stock (collectively, "Awards"). The Company measures the cost of employee services received in exchange for an equity classified Award (such as stock options and restricted stock) based on the grant-date fair value (“GDFV”) of the Award, and recognizes that cost over the period during which the employee is required to provide service (usually the vesting period of the Award). The Company measures the cost of employee services received in exchange for a liability classified Award based on the current fair value of the Award, and remeasures the fair value of the Award at each reporting date.
Included in the accompanying condensed consolidated statements of operations are the following amounts of stock-based compensation, as discussed below:
Liberty—Grants of stock options
Awards granted during the nine months ended September 30, 2019 are summarized as follows:
In addition to the stock option grants to the Liberty CEO and in connection with his employment agreement, during the nine months ended September 30, 2019, Liberty granted 40 thousand and 72 thousand RSUs of Series C Liberty Braves common stock and Series C Liberty Formula One common stock, respectively, of which 38 thousand and 60 thousand, respectively, were performance-based. Such RSUs had a GDFV of $27.73 per share and $33.94 per share, respectively, at the time they were granted. The time-based RSUs cliff vested on March 11, 2019 and the performance-based RSUs cliff vest one year from the month of grant, subject to satisfaction of certain performance objectives. Performance objectives, which are subjective, are considered in determining the timing and amount of the compensation expense recognized. As the satisfaction of the performance objectives becomes probable, the Company records compensation expense. The probability of satisfying the performance objectives is assessed at the end of each reporting period.
The Company did not grant any options to purchase Series A or Series B Liberty SiriusXM, Liberty Braves or Liberty Formula One common stock during the nine months ended September 30, 2019.
Liberty calculates the GDFV for all of its equity classified awards and the subsequent remeasurement of its liability classified and certain performance-based awards using the Black-Scholes Model. Liberty estimates the expected term of the Awards based on historical exercise and forfeiture data. The volatility used in the calculation for Awards is based on
the historical volatility of Liberty common stock and the implied volatility of publicly traded Liberty options. Liberty uses a zero dividend rate and the risk-free rate for Treasury Bonds with a term similar to that of the subject Awards.
The following tables present the number and weighted average exercise price ("WAEP") of Awards to purchase Liberty common stock granted to certain officers, employees and directors of the Company and certain Awards of employees of Lions Gate Entertainment Corp. (formerly employees of Starz).
