As of December 31, 2015 the Company recognized a benefit of $0.4 million for research and development credits pertaining to the Company’s development of software that enables third parties to interact, initiate functions or review data on the Company’s system.

As of December 31, 2015 and 2014, the Company had federal and state net operating loss carryforward remaining of approximately $15.5 million and $15.3 million, respectively.

The Company’s deferred tax asset related to net operating losses (“NOLs”) is less than the actual NOLs available for tax return filings. The U.S. Federal NOL carryforwards include $0.3 million relating to deductions taken with respect to stock option exercises in excess of amounts recognized for financial reporting purposes for which a benefit would be recorded in APIC when realized. This portion of the NOL carryforwards is not included as a component of the Company’s deferred tax asset. Therefore, the Company did not recognize the benefit of tax deductions allowed for stock option exercises in excess of compensation expense recognized for financial reporting purposes, because the Company has NOL carryforwards available and it did not reduce income tax payable.

The U.S. Federal net operating losses can be used for a 20-year period, and if unused, will begin to expire in 2028. The state net operating losses can be used for a period of 5 to 20 years and vary by state, and if unused, begin to expire in 2016, though a substantial portion expires beyond 2017. Tax benefits of operating loss and tax credit carryforwards are evaluated on an ongoing basis, including a review of historical and projected future operating results, the eligible carryforward period, and other circumstances. The Company expects to be able to utilize these net operating loss carryforwards and therefore has not recorded a valuation allowance which is described in more detail below.

The Company’s realization of its deferred tax assets is dependent upon many factors, including, but not limited to, the Company’s ability to generate sufficient taxable income. Management assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to use the existing deferred tax assets. Based on historical performance, sufficient earnings history exists to support the realization of the deferred tax assets. This evidenced ability to generate sufficient taxable income is the basis for the Company’s assessment that the deferred tax assets are more likely than not to be realized.

The Company had no uncertain tax positions for the years ended December 31, 2015 and 2014.

The Company is subject to taxation for Federal and various state jurisdictions in the United States and Canada. The Federal income tax returns of the Company for the years 2012 through 2015 are subject to examination by the Internal Revenue Service. The state income tax returns and other state tax filings of the Company are subject to examination by the state taxing authorities, for various periods generally up to four years after they are filed. Canadian income tax returns of the Company for the years 2011 through 2015 are subject to examination by the Canada Revenue Agency. There are currently no tax audits ongoing.

During the fourth quarter of 2015, the Company completed an update to its analysis of past ownership (as defined under Section 382 of the Code), and as a result, the Company believes that, consistent with previously completed analyses, it has not experienced an ownership change since December 31, 2010. The Company has undertaken a definitive analysis necessary to quantify the effect of ownership change as of December 31, 2010 on the net operating loss carryforwards generated prior to December 31, 2010. Based on the analysis, the Company is subject to an annual limitation of $1.8 million on its use of remaining pre-ownership change net operating loss carryforwards of $4.7 million (and certain other pre-change tax attributes). The Company’s federal net operating loss carryforwards of approximately $15.5 million will begin to expire in various years beginning in 2028.
