7. Income Taxes


The Company evaluates its deferred tax assets on a regular basis to determine if valuation allowances are required. In its evaluation, the Company considers taxable loss carryback availability, expectations of sufficient future taxable income, trends in earnings, existence of taxable income in recent years, the future reversal of temporary differences and available tax planning strategies that could be implemented, if required.  Valuation allowances are established based on the consideration of all available evidence using a more likely than not standard.  Based on the Company’s evaluation, a valuation allowance of $2.5 million was established against its net deferred tax assets for the six months ended June 30, 2013. This amount was in addition to the $16.8 million valuation allowance that was recorded as of December 31, 2012.
