The following weighted average assumptions were used in computing the fair value of stock options using the Black-Scholes option pricing model granted during the years ended December 31, 2017 and 2016:
|  | 2017 |  | 2016 |
Weighted average share price (CDN$) |  | $ | 5.06 |  | $ | 4.17 |
Expected dividend yield |  | 0.0 | % | 0.0 | %
Expected volatility |  | 49.3 | % | 56.9 | %

Expected option life (in years) |  | 4.5 |  | 4.5 |
Weighted average fair value per stock option granted (CDN$) |  | $ | 2.09 |  | $ | 1.92 |
The expected volatility used in the Black-Scholes option pricing model is based primarily on the historical volatility of the Company’s shares. (ii) Restricted Share Plan The Company has a Restricted Share Plan whereby RSUs and RPSUs may be granted to employees, officers and contractors of the Company. The current maximum number of common shares issuable under this plan is 12.3 million. (a) Restricted share units RSUs are generally exercisable into one common share entitling the holder to acquire the common share for no additional consideration. RSUs vest over a three year period. The following table summarizes information about the RSUs outstanding at December 31, 2017 and 2016:
|  | 2017 |  | 2016 |
|  | Number of units (000’s) |  | Weighted average fair value (CDN$/unit) |  | Number of units (000’s) |  | Weighted average fair value (CDN$/unit) |

The vesting requirements are based on certain performance criteria over the vesting period established by the Company. The following table summarizes information about the RPSUs outstanding at December 31, 2017 and 2016:
|  | 2017 |  | 2016 |
|  | Number of units (000’s) |  | Weighted average fair value (CDN$/unit) |  | Number of units (000’s) |  | Weighted average fair value (CDN$/unit) |

(iii) Deferred share unit plan The Company has a DSU plan for its outside directors which provides that each outside director receives, on the last date in each quarter a number of DSUs having a value equal to a minimum of 50% of the compensation of the outside director for the current quarter. Each outside director can elect to receive a greater percentage of their compensation in DSUs. The number of DSUs granted to an outside director is based on the closing price of the Company’s common shares on the Toronto Stock Exchange on the business day immediately preceding the DSU issue date. At such time as an outside director ceases to be a director, the Company will make a cash payment on the outstanding DSUs to the outside director in accordance with the redemption election made by the departing director or in the absence of an election to defer redemption, in accordance with the default redemption provisions provided in the Deferred Share Unit Plan. The number of DSUs granted by the Company and the weighted average fair value per unit issued for the years ended December 31, 2017 and 2016 are as follows:
|  | Years ended December 31, |
|  | 2017 |  | 2016 |
DSUs granted (000’s) |  | 297 |  | 308 |
Weighted average grant-date fair value (CDN$/ unit) |  | $ | 5.15 |  | $ | 4.97 |
There were 1,618,348 DSUs outstanding, for which the Company had recognized a liability of $7.0 million, as at December 31, 2017 (December 31, 2016 - $4.1 million). (iv) Employee share purchase plan (“SPP”) The Company has an employee SPP whereby certain employees of the Company have the opportunity to contribute up to a maximum of 10% of their annual base salary to purchase common shares. Since 2004, the Company has made contributions equal to 50% of the employees’ contributions. The compensation expense related to the employee SPP for the year ended December 31, 2017 was $2.0 million (year ended December 31, 2016 — $2.0 million).
