Income Taxes	3. Income Taxes At the end of each interim reporting period, the Company prepares an estimate of the annual effective income tax rate, which is applied to year-to-date income to compute income tax expense exclusive of discrete items. Tax items discrete to a specific quarter are included in computing the income tax expense for that quarter. The estimated annual effective tax rate used in providing for income taxes on a year-to-date basis may change in subsequent interim periods. The income tax expense for the three and six months ended March 31, 2014 was $320,000 and $736,000, respectively, compared to $123,000 and $219,000, respectively, for the three and six months ended March 31, 2013. The effective tax rate for the three months ended March 31, 2014 was 29%. The effective tax rate for the three months ended March 31, 2014 differs from the statutory rate primarily because of the Domestic Production Activities Deduction (“DPAD”) and the Federal Research and Development Tax Credit (“R&D Tax Credit”). The current year estimated annual effective income tax rate reflects the benefit from the R&D Tax Credit for only the three months ended December 31, 2013 as permitted by ASC Topic 740, because the R&D Tax Credit expired as of December 31, 2013. The effective tax rate for the three months ended March 31, 2013 was 10%. The effective tax rate for the three months ended March 31, 2013 differs from the statutory rate primarily because of the retroactive extension of the R&D Tax Credit. On January 2, 2013, the American Taxpayer Relief Act of 2012 (the “Tax Relief Act”) was enacted, which reinstated retroactively and extended the R&D Tax Credit from January 1, 2012 to December 31, 2013. The 2013 fiscal year estimated annual effective income tax rate reflected a full year benefit from the R&D Tax Credit. In addition, the retroactive benefit for the previously expired period from January 1, 2012 to September 30, 2012 was reflected as a discrete item which further reduced the Company’s income tax expense for the three months ended March 31, 2013. The effective tax rate for the six months ended March 31, 2014 was 29%. The effective tax rate differs from the statutory rate for the six months ended March 31, 2014 primarily because of the Domestic Production Activities Deduction and the R&D Tax Credit. The effective tax rate for the six months ended March 31, 2013 was 13%. The effective tax rate differs from the statutory rate for the six months ended March 31, 2013 primarily because of the favorable impact of the extension of the R&D Tax Credit discussed above. At March 31, 2014, the balance of the deferred tax valuation allowance relates principally to NOL of certain state taxing jurisdictions. The Company will continue to maintain the balance of the valuation allowance until the Company generates a sufficient level of profitability in certain jurisdictions to warrant a conclusion that it is no longer more likely than not that these net state deferred tax assets will not be realized in future periods. There is currently no assurance of such future income before taxes. The Company believes that its estimate of future taxable income is inherently uncertain, and, therefore, further adjustments to the valuation allowance are possible.
