Income Tax Disclosure [Abstract]

Income taxes

The book to tax temporary differences resulting in deferred tax assets and liabilities are primarily net operating loss carry forwards of approximately $8.2 million which expire in 2018 through 2030. A 100% valuation allowance has been established against the deferred tax assets, as utilization of the loss carry forwards and realization of other deferred tax assets cannot be reasonably assured. For the quarter ended June 30, 2015, the Company did not recognize any income tax benefit due to the valuation allowance.
