At April 30, 2017, the Company had net operating loss carryforwards for state income tax purposes of approximately $61,154, which are available to offset future state taxable income. These net operating loss carryforwards expire during the tax years 2020 through 2036. In addition, the Company had state alternative minimum tax credit carryforwards of approximately $7, which are available to reduce future state regular income taxes over an indefinite period.
There was a valuation allowance of $60 and $84 for state net operating loss deferred tax assets as of April 30, 2017 and 2016. The change in the valuation allowance was $(24) and $(144) for the years ending April 30, 2017 and 2016, respectively. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected taxable income, and tax planning strategies in making this assessment.
Total reported tax expense applicable to the Company’s continuing operations varies from the tax that would have resulted from applying the statutory U.S. federal income tax rates to income before income taxes.

The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company had a total of $5,362 and $6,484 in gross unrecognized tax benefits at April 30, 2017 and 2016, respectively, which is recorded in other long-term liabilities in the consolidated balance sheet. Of this amount, $3,522 represents the amount of unrecognized tax benefits that, if recognized, would impact our effective tax rate. Unrecognized tax benefits decreased $1,122 during the twelve months ended April 30, 2017, due primarily to the expiration of certain statutes of limitations exceeding the increase associated with income tax filing positions for the current year.
A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:
|
| | | | | | | |
| 2017 | | 2016 |
Beginning balance | $ | 6,484 |
| | $ | 8,043 |

The total net amount of accrued interest and penalties for such unrecognized tax benefits was $141 and $217 at April 30, 2017 and 2016, respectively, and is included in other long-term liabilities. Net interest and penalties included in income tax expense for the twelve month period ended April 30, 2017 was a decrease in tax expense of $76 and an increase of $65 for the year ended April 30, 2016.
A number of years may elapse before an uncertain tax position is audited and ultimately settled. It is difficult to predict the ultimate outcome or the timing of resolution for uncertain tax positions. It is reasonably possible that the amount of unrecognized tax benefits could significantly increase or decrease within the next twelve months. These changes could result from the expiration of the statute of limitations, examinations or other unforeseen circumstances. The State of Nebraska is examining tax years 2012 through 2014, and the state of Kansas is examining tax years 2013 through 2015. Additionally, the IRS is currently examining tax year 2012. The Company has no other ongoing federal or state income tax examinations. The Company does not have any outstanding litigation related to tax matters.
At this time, the Company’s best estimate of the reasonably possible change in the amount of the gross unrecognized tax benefits is a decrease of $1,242 during the next twelve months mainly due to the expiration of certain statutes of limitations. The federal statute of limitations remains open for the tax years 2012 and forward. Tax years 2012 and forward are subject to audit by state tax authorities depending on open statute of limitations waivers and the tax code of each state.
