Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Employee Stock Purchase Plans During 2015 and 2014, we offered the HSBC International Employee Share Purchase Plan (the “HSBC ShareMatch Plan”) which allows eligible employees to purchase HSBC shares with a maximum monthly purchase of $400 in 2015 and $420 in 2014. For every three shares purchased under the HSBC ShareMatch Plan (the "Investment Share") the employee is awarded an additional share at no charge (the "Matching Share"). The Investment Share is fully vested at the time of purchase while the Matching Share vests at the end of three years contingent upon continuing employment with the HSBC Group.

Prior to 2014, the HSBC Holdings Savings-Related Share Option Plan (the "HSBC Sharesave Plan") allowed eligible employees to enter into savings contracts of one, three or five year lengths, with the ability to decide at the end of the contract term to either use their accumulated savings to purchase HSBC ordinary shares at a discounted option price or have the savings plus any interest repaid in cash. The Sharesave Plan was discontinued in 2013.

Compensation expense for Employee Stock Purchase Plans was not significant in 2015, 2014 or 2013.

Restricted Share Plans Under the HSBC Group Share Plan, share-based awards have been granted to key employees, typically in the form of restricted share units. These shares have been granted subject to either time-based vesting or performance-based vesting, typically over three to five years. Annual awards to employees are generally subject to three-year time-based graded vesting. We also issue a small number of off-cycle grants each year, primarily for reasons related to recruitment of new employees. Compensation expense for restricted share awards totaled $4 million, $5 million and $4 million in 2015, 2014 and 2013, respectively. As of December 31, 2015, future compensation cost related to grants which have not yet fully vested is approximately $5 million. This amount is expected to be recognized over a weighted-average period of 1.11 years.
