Share-based Compensation [Abstract]

Stock-Based Compensation

Stock-Based Compensation

The Company has granted to certain of its directors, employees and employees of its subsidiaries stock appreciation rights ("SARs"), restricted stock grants and options to purchase shares of Liberty 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 grants) 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 a liability classified Award (such as stock appreciation rights 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.

Included in the accompanying condensed consolidated statements of operations are the following amounts of stock-based compensation, a portion of which relates to TripAdvisor as discussed below:

	Three months ended June 30,			Six months ended June 30,
	2013		2012	2013		2012
	(amounts in millions)
Operating expense	$	5	—	13	—	—
Selling, general and administrative expense	39		18	73		35
	$	44	18	86		35

During the six months ended June 30, 2013, Liberty granted, primarily to QVC employees, 4.2 million options to purchase shares of Series A Liberty Interactive common stock. Such options had a weighted average grant-date fair value of $8.16 per share and vest semi-annually over the four year vesting period.

The Company has calculated the grant-date fair value for all of its equity classified Awards and any subsequent remeasurement of its liability classified Awards using the Black-Scholes Model. The Company 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's stock and the implied volatility of publicly traded Liberty options. The Company uses a zero dividend rate and the risk-free rate for Treasury Bonds with a term similar to that of the subject options.

Other

Certain of the Company's other subsidiaries have stock based compensation plans under which employees and non-employees are granted options or similar stock based awards. Awards made under these plans vest and become exercisable over various terms. The awards and compensation recorded, if any, under these plans is not significant to Liberty.
