Significant Accounting Policies [Text Block]	3. The Company ’s significant accounting policies are described below . Management Estimates. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates . Cash Equivalents. Cash equivalents are considered to be highly liquid securities having an original maturity of 90 . Stock-Based Compensation .

The Company classifies the benefits of tax deductions in excess of the compensation cost recognized for the options (excess tax benefit) as financing cash flows. The fair value of each option award is estimated as of the date of grant using the Black-Scholes option-pricing model. The fair value of each restricted stock award is equal to the Company’s stock price on the date the award is granted . Income Taxes. The Company follows the liability method of accounting for income taxes under which deferred tax assets and liabilities are recognized for the future tax consequences of (i) temporary differences between the tax basis of assets and liabilities and their reported amounts in the consolidated financial statements and (ii) operating loss and tax credit carry-forwards for tax purposes.

Accounting Policies [Abstract]
Use of Estimates, Policy [Policy Text Block]	Management Estimates. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates .
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash Equivalents. Cash equivalents are considered to be highly liquid securities having an original maturity of 90 .
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock-Based Compensation . The Company applies the fair value method of accounting for stock-based compensation. Under this method, compensation cost is measured at the grant date based on the fair value of the award and is recognized over the award vesting period. The Company classifies the benefits of tax deductions in excess of the compensation cost recognized for the options (excess tax benefit) as financing cash flows. The fair value of each option award is estimated as of the date of grant using the Black-Scholes option-pricing model. The fair value of each restricted stock award is equal to the Company’s stock price on the date the award is granted .
Income Tax, Policy [Policy Text Block]	Income Taxes. The Company follows the liability method of accounting for income taxes under which deferred tax assets and liabilities are recognized for the future tax consequences of (i) temporary differences between the tax basis of assets and liabilities and their reported amounts in the consolidated financial statements and (ii) operating loss and tax credit carry-forwards for tax purposes.
