(3) 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 Awards
Options granted during the three months ended March 31, 2021 are summarized as follows:
The Company did not grantto purchase or Liberty SiriusXM, Liberty Braves or Liberty Formula One common stock during the three months ended March 31, 2021.
Also during the three months ended March 31, 2021, the Company granted 31 thousand and 65 thousand performance-based RSUs of Series C common stock of Liberty Braves and Liberty Formula One, respectively, to our CEO. The RSUs had a GDFV of $31.24 and $45.88 per share, respectively, and cliff vest one year from the month of grant, subject to the satisfaction of certain performance objectives. Performance objectives, which are subjective, are considered in determining the timing and amount of compensation expense recognized. When 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.
Liberty calculates the GDFV for all of its equity classified Awards and the subsequent remeasurement of its liability classified 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, as well as the weighted average remaining life and aggregate intrinsic value of the Awards.
