6. ADDITIONAL PAID IN CAPITAL | Stock-based compensation |
|
We have options outstanding and exercisable that were issued under two plans, the Fixed Stock Option Plan (“FSOP”) and the 10% Rolling Stock Option Plan (“RSOP”). |
|
The FSOP was originally approved by shareholders on December 11, 2002 and subsequently approved by shareholders on December 7, 2009, following certain amendments to the FSOP. The FSOP expired upon the adoption of the 10% Rolling Stock Option Plan, which was approved by shareholders on December 2, 2011, and as such, we may no longer grant options under the FSOP. However, the terms of the FSOP continue to govern all prior awards granted under such plan until such awards have been cancelled, forfeited or exercised in accordance with the terms thereof. Under the FSOP, we could grant stock options for up to 5,779,347 common shares to eligible directors, officers, employees or consultants. The maximum term of an option was five years. The exercise price of an option was not less than the closing price on the last trading day preceding the grant date, less allowable discounts in accordance with the policies of the TSX and the NYSE MKT. All options granted under the FSOP vested as follows: 20% upon each of 4 months, 8 months, 12 months, 15 months and 18 months after the date of grant. As of December 31, 2014, there were 1,915,000 stock options outstanding under the FSOP with a weighted-average exercise price of $7.37, all of which were exercisable. |
|
On December 2, 2011, at the Annual General Meeting, our shareholders approved by way of an ordinary resolution the terms of a new plan, the RSOP, which established the maximum number of common shares which may be issued under the RSOP as a variable amount equal to 10% of the issued and outstanding common shares on a non-diluted basis. Under the RSOP, our Board of Directors may from time-to-time grant stock options to individual eligible directors, officers, employees or consultants. The maximum term of any stock option is ten years. The exercise price of a stock option is not less than the closing price on the last trading day preceding the grant date, less allowable discounts in accordance with the policies of the TSX and the NYSE MKT. The Board retains the discretion to impose vesting periods on any options granted. All options granted to date vest as follows: 20% upon each of 4 months, 8 months, 12 months, 15 months and 18 months after the date of grant. As of December 31, 2014, there were 2,430,500 stock options outstanding under the RSOP with a weighted-average exercise price of $3.42, of which 2,035,500 options were exercisable with a weighted-average exercise price of $3.81. |

The fair value of stock option awards granted to directors, officers or employees of the Company are estimated on the grant date using the Black-Scholes option pricing model and the closing price of our common shares as quoted on either the TSX or NYSE MKT on the grant date. The significant assumptions used to estimate the fair value of stock option awards using the Black-Scholes model are as follows: |
