Stock-Based Compensation Plans | 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 three months ended March 31, 2015:
|  | Number of Options |  |  | Weighted Average Exercise Price |  |  | Weighted Average Grant-Date Fair Value |
Outstanding at December 31, 2014 |  |  | 728,640 |  |  | $ | 19.55 |  |  |  |  |
Granted - at discount |  |  | 54,717 |  |  | $ | 0.00 |  |  | $ | 36.18 |
- at market value |  |  | 23,550 |  |  | $ | 43.95 |  |  | $ | 9.89 |

Outstanding at March 31, 2015 |  |  | 689,056 |  |  | $ | 20.96 |  |  |  |  |
At March 31, 2015, there were 115,793 stock options that were exercisable, of which 39,000 had performance conditions attached. The stock option compensation cost for the first three months of 2015 was $0.9 million (2014 – $0.6 million). The total intrinsic value of options exercised in the first three months of 2015 was $2.0 million (2014 – $0.5 million). The total compensation cost related to non-vested stock options not yet recognized at March 31, 2015 was $5.7 million and this cost is expected to be recognized over the weighted-average period of 2.34 years. Stock equivalent units The following table summarizes the transactions of the Company’s SEUs for the three months ended March 31, 2015:
|  | Number of SEUs |  |  | Weighted Average Exercise Price |  |  | Weighted Average Grant-Date Fair Value |
Outstanding at December 31, 2014 |  |  | 286,563 |  |  | $ | 3.41 |  |  |  |  |
Granted - at discount |  |  | 69,280 |  |  | $ | 0.00 |  |  | $ | 36.65 |
- at market value |  |  | 6,336 |  |  | $ | 43.95 |  |  | $ | 9.89 |
Exercised |  |  | (81,695 | ) |  | $ | 2.31 |  |  |  |  |
Forfeited |  |  | (1,495 | ) |  | $ | 29.56 |  |  |  |  |
Outstanding at March 31, 2015 |  |  | 278,989 |  |  | $ | 3.67 |  |  |  |  |
At March 31, 2015 there were 73,890 SEUs that are exercisable, of which 63,838 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 three months of 2015 was $1.0 million (2014 - $0.6 million). The total intrinsic value of SEUs exercised in the first three months of 2015 was $1.9 million (2014 – $3.0 million). The weighted-average remaining vesting period of non-vested SEUs is 2.03 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) |  | 2015 |  |  | 2014 |
Balance at January 1 |  | $ | 0.1 |  |  | $ | 0.0 |
Compensation charge for the period |  |  | 0.1 |  |  |  | 0.1 |
Balance at March 31 |  | $ | 0.2 |  |  | $ | 0.1 |
The following assumptions were used in the Monte Carlo model at March 31:
|  | 2015 |  |  | 2014 |
Dividend yield |  |  | 1.19 | % |  |  | 1.11 | %
Volatility of Innospec’s share price |  |  | 25.91 | % |  |  | 36.04 | %
Risk free interest rate |  |  | 0.89 | % |  |  | 0.90 | %
