Share-based Compensation [Text Block] | 13 Share-based Compensation (i) Options The Company grants share options to officers and employees and restricted shares of common stock to its non-employee directors as rewards for their services. Stock Option Plan In May 2005, the Board of Directors adopted the China BAK Battery, Inc. 2005 Stock Option Plan (the “Plan”). The Plan originally authorized the issuance of up to 800,000 shares of the Company’s common stock, pursuant to stock options granted under the Plan, or as grants of restricted stock. The exercise price of options granted pursuant to the Plan must be at least equal to the fair market value of the Company’s common stock at the date of the grant. Fair market value is determined at the discretion of the designated committee on the basis of reported sales prices for the Company’s common stock over a ten-business-day period ending on the grant date. The Plan will terminate on May 16, 2055. On July 28, 2008, the Company’s stockholders approved certain amendments to the Plan, including an amendment increasing the total number of shares available for issuance under the Plan to 1,600,000. Pursuant to the Plan, the Company granted options to purchase 400,000 shares of common stock with an exercise price of $31.25 per share and a contractual life of 6 years on May 16, 2005. In accordance with the vesting provisions of the grants, the options became vested and exercisable under the following schedule:
|  | Percentage of |  | Initial
Number of Shares |  | Options Issued |  | Vesting Date
160,000 |  | 40% |  | July 1, 2007
120,000 |  | 30% |  | January 1, 2008
120,000 |  | 30% |  | July 1, 2008
400,000 |  | 100% |  |
Subsequent to the grant date, options to purchase 40,000 shares of common stock were forfeited because the optionees terminated their employment with the Company. In addition, on September 28, 2006, options to purchase a total of 280,000 shares of common stock were cancelled pursuant to the Termination and Release Agreements signed on that day. Pursuant to the Plan, the Company also granted options to purchase 300,300 shares of the Company’s common stock with a weighted-average exercise price of $16.45 per share on June 25, 2007. In accordance with the vesting provisions of the grants, the options will become vested and exercisable during the period from March 31, 2007 to February 9, 2012 according to each employee’s respective agreement. A summary of share option plan activity for these options during the three months ended December 31, 2012 is presented below:
