Income Tax Disclosure [Abstract] |
Income Taxes | NOTE 11 — Income Taxes Deferred tax expense is related to the deferred tax liability on the portion of the Company's goodwill amortized for tax purposes.

As of December 31, 2014, the Company did not recognize deferred tax assets relating to an excess tax benefit for stock-based compensation deduction of $2,046,000. Unrecognized deferred tax benefits will be accounted for as a credit to additional-paid-in-capital when realized through a reduction in income taxes payable. Deferred income tax reflects the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amount used for income tax purposes. Significant components of net deferred tax assets are as follows:
|  | Years Ended December 31,
Deferred tax assets: |  | 2014 |  | 2013
Net operating loss carryforwards |  | $ | 9,729,000 |  |  | $ | 10,347,000 |
Credits |  |  | 716,000 |  |  |  | 682,000 |
Capitalized research and development costs |  |  | 122,000 |  |  |  | 295,000 |
Other acquired intangibles |  |  | 134,000 |  |  |  | 165,000 |
Accruals not currently deductible |  |  | 1,356,000 |  |  |  | 1,318,000 |
Total deferred tax assets |  |  | 12,057,000 |  |  |  | 12,807,000 |
Valuation allowance for deferred tax assets |  |  | (12,032,274 | ) |  |  | (12,788,334 | )
Net deferred tax assets |  |  | 24,726 |  |  |  | 18,666 |
Deferred tax liability: |  |  |  |  |  |  |  |
Acquired intangibles |  |  | (168,000 | ) |  |  | (130,000 | )
Net deferred tax liabilities |  | $ | (143,274 | ) |  | $ | (111,334 | )
The Company has not generated taxable income in any periods in any jurisdiction, foreign or domestic. The Company has maintained a full valuation allowance for all deferred tax assets. As of December 31, 2014, the Company had net operating loss carryforwards for federal income tax purposes of approximately $28,974,000 which will expire at various dates beginning in 2017 and through 2033, and federal research and development tax credits of approximately $450,000, which will expire at various dates beginning in 2018 and through 2034. As of December 31, 2014, the Company had net operating loss carryforwards for state income tax purposes of approximately $18,006,000, which will expire at various dates in 2013 and through 2033, and state research and development tax credits of approximately $280,000, which can be carried forward indefinitely. During 2014, approximately $3,936,000 of state net operating loss carryforwards expired unutilized. Utilization of the net operating loss and tax credit carryforwards is subject to annual limitations due to the ownership change limitations provided by the Internal Revenue Code Section 382 and similar state provisions. The annual limitation will result in the expiration of the net operating loss and credit carryforwards before utilization. The deferred tax assets for the year ended December 31, 2014 reflect estimates of Section 382 limitations. A reconciliation of the beginning and ending amount of unrecognized tax benefits (“UTBs”), excluding interest and penalties, is as follows:
|  | Amount
Beginning balance at January 1, 2014 |  | $ | 682,000 |
Increases in UTBs taken in prior years |  |  | 34,000 |
Increases in UTBs taken in current year |  |  | 14,000 |
Ending balance at December 31, 2014 |  | $ | 730,000 |
Future changes in the unrecognized tax benefit will have no impact on the effective tax rate due to the existence of the valuation allowance. It is the Company's policy to include interest and penalties related to tax positions as a component of income tax expense. No interest was accrued for the period ended December 31, 2014. The Company estimates that the unrecognized tax benefit will not change significantly within the next twelve months. The Company files its tax returns as prescribed by the tax laws of the jurisdictions in which it operates. The Company is not currently under audit in any of its jurisdictions where income tax returns are filed. The tax years 1996 to 2013 remain open to examination by the major domestic taxing jurisdictions to which the Company is subject, and for the years 2002 to 2009 for the international taxing jurisdictions to which the Company is subject.
