Note 10 - Income taxes At the end of each interim reporting period, the Company estimates its effective income tax rate expected to be applicable for the full year. This estimate is used to determine the income tax provision or benefit on a year-to-date basis and may change in subsequent interim periods. The Company’s effective tax rate (benefit) provision for the three months ended April 30, 2015 was (3.2%) compared to a 1.5% provision during the three months ended April 30, 2014. The Company’s effective tax rate provision was deminimus for the nine months ended April 30, 2015 and 2014. The tax provision or benefit for the periods was based on state, local and foreign taxes, net of the benefit for amortization of foreign intangibles. The Company’s effective tax rate for both periods differed from the expected net operating loss carryforward benefit at the U.S. federal statutory rate of 34% primarily due to the inability to recognize such benefit. The carryforward benefit cannot be recognized because of uncertainties relating to future taxable income in terms of both its timing and its sufficiency, which would enable the Company to realize the federal carryforward benefit. The Company files a consolidated Federal income tax return. The Company files combined returns with California, Michigan and New York State and City for certain subsidiaries. Other subsidiaries file separate state and foreign tax returns. |
