NOTE 13 – STOCK-BASED COMPENSATION PLANS

The Company grants stock options and stock equivalent units (“SEUs”) from time to time as a long-term performance incentive. In certain cases the grants are subject to performance conditions such as the Company’s stock price. Where performance conditions apply the Monte Carlo simulation model is used to determine the fair values. Otherwise the Black-Scholes model is used to determine the fair values.

Stock option plans

The following table summarizes the transactions of the Company’s stock option plans for the six months ended June 30, 2016:


	Number of Options			Weighted Average Exercise Price		Weighted Average Grant-Date Fair Value
Outstanding at December 31, 2015		667,439		$	19.87	$	20.19
Granted - at discount		56,046		$	0.00	$	36.13
- at market value		24,794		$	44.34	$	9.17
Exercised		(50,425	)	$	5.58	$	28.00
Forfeited		(18,539	)	$	18.52	$	23.32

Outstanding at June 30, 2016		679,315		$	20.22	$	20.44

At June 30, 2016, there were 111,004 stock options that were exercisable, of which 25,912 had performance conditions attached.

The stock option compensation cost for the first six months of 2016 was $1.9 million (2015 – $1.8 million). The total intrinsic value of options exercised in the first six months of 2016 was $1.6 million (2015 – $2.0 million).

The total compensation cost related to non-vested stock options not yet recognized at June 30, 2016 was $4.7 million and this cost is expected to be recognized over the weighted-average period of 2.14 years.

Stock equivalent units

The following table summarizes the transactions of the Company’s SEUs for the six months ended June 30, 2016:


	Number of SEUs			Weighted Average Exercise Price		Weighted Average Grant-Date Fair Value
Outstanding at December 31, 2015		279,750		$	3.79	$	31.72
Granted - at discount		63,653		$	0.00	$	35.71
- at market value		7,316		$	44.18	$	9.11
Exercised		(42,123	)	$	2.05	$	25.73
Forfeited		(8,980	)	$	4.41	$	30.73

Outstanding at June 30, 2016		299,616		$	4.19	$	32.89

At June 30, 2016 there were 67,265 SEUs that are exercisable, of which 58,663 had performance conditions attached.

The charges for SEUs are spread over the life of the award subject to a revaluation to fair value each quarter. The revaluation may result in a charge or a credit to the income statement in the quarter dependent upon our share price and other performance criteria.

The SEU compensation cost for the first six months of 2016 was $0.0 million (2015 - $1.4 million). The total intrinsic value of SEUs exercised in the first six months of 2016 was $1.2 million (2015 - $2.1 million).

The weighted-average remaining vesting period of non-vested SEUs is 1.84 years.

Additional exceptional long-term incentive plan

A maximum of $3.0 million of our cash-settled long-term incentives is accounted for as share-based compensation and the fair value is calculated on a quarterly basis using a Monte Carlo model. The fair values at each of the balance sheet dates are summarized as follows:


(in millions)	2016			2015
Balance at January 1	$	1.0		$	0.1
Compensation (credit)/charge for the period		(0.7	)		0.0
Balance at June 30	$	0.3		$	0.1

The following assumptions were used in the Monte Carlo model at June 30:


	2016			2015
Dividend yield		1.39	%		1.29	%
Volatility of Innospec’s share price		24.99	%		24.38	%
Risk free interest rate		0.71	%		1.01	%
