The Company has research and development tax credit carry-forwards of approximately $1,285,000 at December 31, 2014, that can be used to reduce future U.S. income tax liabilities and expire principally between 2020 and 2034. The Company has foreign tax credit carry-forwards of approximately $359,000 at December 31, 2014, that are available to reduce future U.S. income tax liabilities subject to certain limitations.

Additionally, the Company has federal alternative minimum tax (“AMT”) credits of approximately $111,000 at December 31, 2014, that are available to offset future U.S. federal tax liabilities, and have no expiration. Based on the Company’s assessment of the uncertainty surrounding the realization of the favorable U.S. tax attributes in future tax returns in accordance with the provisions of ASC 740, Income Taxes, the Company has determined that a full valuation allowance against our otherwise recognizable U.S. net deferred tax assets is required. The Company has recorded a full valuation allowance to reduce deferred tax assets to the amount that is more likely than not to be realized. When assessing the need for valuation allowances, the Company considers future taxable income and ongoing prudent and feasible tax planning strategies. Should a change in circumstances lead to a change in judgment about the ability to realize deferred tax assets in future years, the Company will adjust related valuation allowances in the period that the change in circumstances occurs, along with a corresponding increase or charge to income.
