Deferred Compensation Plan [Abstract]
Compensation Related Costs, General [Text Block]	Deferred Compensation Plan The Company has a nonqualified deferred compensation plan for certain officers. Provision has been made for the compensation which is payable upon their retirement or death. The deferred compensation is to be paid to the individual or their beneficiaries over a period of ten years commencing with the first year following retirement or death. As of December 31, 2011, there were no further payments required under the plan. The Company also has deferred bonus agreements with several key executives whereby funds are contributed to "rabbi" trusts held for the benefit of the executives. The funds held in the rabbi trusts are included in cash and cash equivalents and the corresponding deferred compensation obligation is included in accrued expenses, accounts payable and other liabilities on the Consolidated Balance Sheets . Pursuant to U.S. GAAP, the portion of the rabbi trusts invested in shares of the Company has been reflected as treasury stock on the Consolidated Balance Sheets at December 31, 2011 and 2010.

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.
