6.  Income Taxes

The Company did not recognize any income tax expense for the three months ended March 31, 2014 and 2013. The Company's effective tax rate will fluctuate from period to period due to several factors inherent in the nature of the Company's operations and business transactions. The factors that most significantly impact this rate include the variability of licensing transactions in foreign jurisdictions.

Accounting standards provide for the recognition of deferred tax assets if realization of such assets is more likely than not.  Based upon the weight of available evidence, which includes the Company's historical operating performance and carry-back potential, it has determined that total deferred tax assets should be fully offset by a valuation allowance.
