Deferred Compensation Arrangement [Abstract]
Deferred Compensation Arrangement	22. Deferred compensation arrangement The Company established a non-qualified deferred compensation arrangement (the “Deferred Compensation Arrangement”) which is available to certain US employees. The Deferred Compensation Arrangement permits the deferral of up to 10% of base salary with the Company matching 100% of such contributions. Employees will receive the benefit, including a return on investment, on termination, retirement or other specified departures. The Company funds the deferred compensation obligations by investing in a non-qualified corporate owned life insurance policy (“COLI”), whereby funds are invested and the account balance fluctuates with the investment returns on those funds. The expected benefit to be paid on termination of $1,030,000 (2014: $775,000) is presented in other non-current liabilities. The cash surrender value of the COLI asset of $1,138,000 (2014: $782,000) is classified within other non-current assets, with changes in the deferred compensation liability and COLI asset charged to selling, general and administrative expenses (note 6).

The entire disclosure for compensation costs, including compensated absences accruals, compensated absences liability, deferred compensation arrangements and income statement compensation items. Deferred compensation arrangements may include a description of an arrangement with an individual employee, which is generally an employment contract between the entity and a selected officer or key employee containing a promise by the employer to pay certain amounts at designated future dates, usually including a period after retirement, upon compliance with stipulated requirements. This type of arrangement is distinguished from broader based employee benefit plans as it is usually tailored to the employee. Disclosure also typically includes the amount of related compensation expense recognized during the reporting period, the number of shares (units) issued during the period under such arrangements, and the carrying amount as of the balance sheet date of the related liability.
