The Company’s income tax expense (benefit) of ($14,000) and $7,000 for the six months ended January 31, 2014 and 2013, respectively, consisted of estimated current state income taxes of Cortelco. No deferred taxes are provided in the accompanying financial statements due to the valuation allowance established.
 
As of January 31, 2014, the Company has federal and state net operating loss carryforwards of approximately $28,000,000 which expire at various dates through 2034. The Internal Revenue Code provides limitations on utilization of existing net operating losses against future taxable income based upon changes in share ownership. If these changes occur, the ultimate realization of the net operating loss carryforwards could be limited which would result in some portion of the carryforwards becoming permanently impaired.
