The total valuation allowance relates to deferred tax assets of both domestic and foreign subsidiaries.  For the year ended April 30, 2013, the change in valuation allowance was an increase of $445,000 which consists of the $490,000 deferred tax provision less a foreign exchange adjustment of $45,000.  The change in valuation allowance during the year ended April 30, 2012 was a decrease of $3.1 million, including foreign exchange adjustments of $58,000 and the $43,000 tax effect of unrealized gains on marketable securities.

During the fourth quarter of fiscal year 2012, the Company reduced its valuation allowance against deferred tax assets in the amounts of $3.1 million.  This recognition was the result of an evaluation of the Company’s net operating losses incurred in prior years, its recent history of three consecutive years of increasing profitability and recent contract bookings which increased the Company’s long-term backlog to a higher level.  Company management believed such contracts would enable the Company to continue to generate operating profits in fiscal year 2013 and beyond.  These adjustments were made in the fourth quarter of fiscal year 2012 as the Company waited until it had results for the full year to make final its determination, given the existence of a loss in recent years, that it met the accounting threshold for determination that the recovery of the deferred tax asset was more likely than not and to estimate the appropriate balance of the valuation allowance, based on all available information.  The amount of the non-cash valuation allowance reduction was based on management’s estimates of taxable income by reporting segment and taxing jurisdictions and the periods over which the Company believes deferred tax assets will be recoverable.

At April 30, 2013, the Company has available approximately $2.7 million in net operating losses available to offset future income of certain of its foreign subsidiaries.  These loss carryforwards have no expiration date.  As a result of the acquisition of FEI-Elcom, the Company has a federal net operating loss carryforward of $6.6 million which may be applied in annually limited amounts to offset future U.S.-sourced taxable income over the next 19 years.

The Company has evaluated its tax positions and has concluded that the tax positions meet the more-likely-than-not recognition threshold as specified under accounting standards.  It is difficult to predict what would occur to change the Company’s unrecognized tax benefits over the next twelve months.  The Company believes, however, that there should be no change during the next twelve months.  The Company's tax returns for April 30, 2006 and 2007 have been examined by the Internal Revenue Service, which resulted in no material adjustments.  The Company's tax years from April 30, 2005 through April 30, 2013 remain open to examination by state tax authorities and tax years from April 30, 2008 through April 30, 2013 remain open for examination by the Internal Revenue Service.
