Equity Classified Awards - Stock Options

The estimated fair value of the stock options granted during the six months ended June 30, 2016 was calculated using a Black-Scholes option pricing model. The following summarizes the assumptions used in the Black-Scholes model:

Risk-free interest rate	1.08	%
Weighted average historical volatility	27.1	%
Dividend yield	4.05	%
Expected years until exercise	4.5
Weighted average fair value of options granted	$13.55

Stock option balances as of June 30, 2016 and related activity for the six months ended June 30, 2016 were as follows:

	Shares		Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (in Years)	Aggregate Intrinsic Value (in Millions)
Outstanding at December 31, 2015	504,462		$	69.99
Granted	255,825		90.90
Exercised	(36,088	)	24.39
Outstanding at June 30, 2016	724,199		79.65		7.6	$	8.4
Vested at June 30, 2016 and Expected to Vest	668,490		78.46		7.5	$	8.4
Exercisable at June 30, 2016	361,851		$	64.98	5.9	$	8.3

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between the closing stock price of the Company’s common stock on the last trading day of the second quarter of 2016 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on June 30, 2016. The aggregate intrinsic value will change based on the fair market value of the Company’s common stock and the number of in-the-money options.

Outstanding balances as of June 30, 2016 and activity related to restricted stock and restricted stock units for the six months ended June 30, 2016 were as follows:

Liability Classified Awards - Long-Term Incentive Awards

The Company has granted cash long-term incentive awards (“LTIP awards”) to certain employees. Annual LTIP awards vest over a three-year period and are determined using a multiplier from 0% to 200% of the target award based on the total stockholder return of DineEquity common stock compared to the total stockholder returns of a peer group of companies. Although LTIP awards are only paid in cash, since the multiplier is based on the price of the Company's common stock, the awards are considered stock-based compensation in accordance with U.S. GAAP and are classified as liabilities. For the three months ended June 30, 2016 and 2015, an expense of $0.3 million and a credit of $1.1 million, respectively, were included in total stock-based compensation expense related to LTIP awards. For the six months ended June 30, 2016 and 2015, an expense of $1.1 million and a credit of $0.8 million, respectively, were included in total stock-based compensation expense related to LTIP awards. At June 30, 2016 and December 31, 2015, liabilities of $2.8 million and $1.6 million, respectively, related to LTIP awards were included as part of accrued employee compensation and benefits in the Consolidated Balance Sheets.
