The Company has recorded a full valuation allowance on all deferred tax assets. Although a full valuation allowance has been recorded for all deferred tax assets, including net operating loss carryforwards (“NOLs”), these NOLs remain available to the Company to offset future taxable income and reduce cash tax payments. IEC had federal gross NOLs for income tax purposes of approximately $32.9 million at September 30, 2017, expiring mainly in years 2022 through 2025 and 2034 through 2035. The Company also has additional state NOLs available in several jurisdictions in which it files state tax returns.
 
Recent New York state corporate tax reform has resulted in the reduction of the business income base rate for qualified manufacturers in New York State to 0% beginning in fiscal 2016 for IEC. The credits cannot be utilized unless the New York State tax rate is no longer 0%.

The Company will continue to monitor and evaluate the positive and negative evidence considered in arriving at the above conclusion, in order to assess whether such conclusion remains appropriate in future periods, given our current operating results in fiscal 2017 and forecasted operating results in fiscal 2018.
