Management Transition Charges [Abstract]
Management Transition Charges	Note 17. Management Transition Charges In June 2011, the Company's then Chairman of the Board, Chief Executive Officer and President retired, and the employment of the Company's then Chief Financial Officer ended. Pursuant to their respective employment and/or separation agreements, (a) they are to receive an aggregate of approximately $3.7 million in cash severance payments (including the cost of related payroll taxes and benefits, and substantially all of which has been funded), and (b) all of their unvested restricted share grants became vested and all related amounts were written off (an aggregate of approximately $2.0 million – see "Stock-Based Compensation" below). Together with approximately $0.8 million of other non-recurring costs, primarily professional fees and expenses related to the hiring of a new President/Chief Executive Officer and Chief Financial Officer, the Company recorded an aggregate of approximately $6.5 million as "management transition charges".

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.
