|Share-based Compensation [Abstract]
Prior to the Split-Off, Liberty Interactive granted, and Liberty has since granted, to certain of its directors, employees and employees of its subsidiaries options and stock appreciation rights ("SARs") to purchase shares of its common stock (collectively, "Awards"). The Company measures the cost of employee services received in exchange for an Award of equity instruments (such as stock options and restricted stock) based on the grant-date fair value 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 an Award of liability instruments (such as SARs that will be settled in cash) based on the current fair value of the Award, and remeasures the fair value of the Award at each reporting date.
In connection with the Spin-Off in January 2013, all outstanding Awards with respect to Liberty Capital common stock ("Liberty Capital Award") were adjusted pursuant to the anti-dilution provisions of the incentive plans under which the equity awards were granted, such that a holder of a Liberty Capital Award received (other than those held by Starz employees, as discussed below):
The exercise prices and number of shares subject to the Liberty Award and the Starz Award were determined based on 1) the exercise prices and number of shares subject to the Liberty Capital Award, 2) the pre-distribution trading price of Liberty Capital common stock and 3) the post-distribution trading prices of Liberty common stock and Starz common stock, such that (other than those held by Starz employees, as discussed below) all of the pre-distribution intrinsic value of the Liberty Capital Award was allocated between the Liberty Award and the Starz Award for the Company's corporate employees and directors. For employees of Starz, LLC, the pre-distribution intrinsic value of the vested Liberty Capital Award was allocated between a vested Liberty Award and a vested Starz Award, while the pre-distribution intrinsic value of the unvested Liberty Capital Award was maintained solely within an unvested Starz Award.
Following the Spin-Off, employees of Liberty and Starz hold Awards in both Liberty common stock and Starz common stock. The compensation expense relating to the employees of Liberty is recorded at Liberty and the compensation expense relating to employees of Starz is recorded at Starz.
Included in the accompanying condensed consolidated statements of operations are the following amounts of stock-based compensation, a portion of which relates to SIRIUS XM as discussed below:
During the nine months ended September 30, 2013, the Company did not grant any options to purchase shares of Series A common stock.
Liberty Interactive previously calculated, and Liberty calculates, the grant-date fair value 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 table presents 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 Starz.
The following table provides additional information about outstanding Awards to purchase Liberty common stock at September 30, 2013.
As of September 30, 2013, the total unrecognized compensation cost related to unvested Liberty Awards was approximately $75 million, including compensation associated with the option exchange that occurred in December 2012. Such amount will be recognized in the Company's consolidated statements of operations over a weighted average period of approximately 2.2 years.
As of September 30, 2013, Liberty reserved 3.9 million Series A common stock for issuance under exercise privileges of outstanding stock Awards.
