| Compensated absences and severance, principally due to accruals for financial reporting purposes | $ | — | $ | 3,000 | ||||

The valuation allowance increased by $595,000 and $326,000 for the fiscal years ended April 30, 2017 and 2016, respectively. Management believes sufficient uncertainty exists regarding the realization of the deferred tax asset items and that a valuation allowance is required. Management considers projected future taxable income and tax planning strategies in making this assessment. The amount of deferred tax assets considered realizable could materially change in the future if estimates of future taxable income change.
The Company has Federal and state net operating loss carry-forwards of approximately $32,400,000 and $4,400,000, respectively. These can be used to offset future taxable income and expire between 2023 and 2037 for Federal tax purposes and 2029 and 2037 for state tax purposes. However, the future use of some or all of such carried forward losses may be limited by Sec. 382 of Internal Revenue Code in the event of an ownership change.
