Stock Based Compensation: [Abstract]
Stock Based Compensation:	Stock Based Compensation: The Company’s Stock Option Plan (the “Plan”), permitted the grant of share options to its directors, officers and employees. Under the terms of the Plan no additional shares can be issued. Option awards were granted with an exercise price equal to the market price of the Company's common shares at the date of grant, with a vesting period of 5 years and have 10-year contractual terms. At March 31, 2012 there were 5,000 outstanding options of which 3,000 were fully vested and are exercisable. The fair value of each option award is estimated on the date of grant using a Black-Scholes model. Total compensation cost charged against income for the stock option plan for the three month period ended March 31, 2012 was not material. No related income tax benefit was recorded.

Disclosure of compensation-related costs for share-based compensation which may include disclosure of policies, compensation plan details, allocation of stock compensation, incentive distributions, share-based arrangements to obtain goods and services, deferred compensation arrangements, employee stock ownership plan details and employee stock purchase plan details.
