All of our unrecognized tax benefits would have an impact on the effective tax rate if recognized. It is reasonably possible that the amount of unrecognized tax benefits could change due to one or more of the following events in the next 12 months: expiring statutes, audit activity, tax payments, or competent authority proceedings. We are not able to reasonably estimate the amount or the future periods in which changes in unrecognized tax benefits may be resolved; however, we do not anticipate any significant changes within the next 12 months. Interest and penalties incurred associated with uncertain tax positions are included in income tax expense. Our fiscal 2014 financial results included a deferred asset tax valuation allowance of $2,297. The corresponding deferred tax asset was related to potential capital losses from an investment in an affiliate ("affiliate") that is a United States entity. During the fourth quarter of fiscal 2014, we were notified that the affiliate had sold off a significant portion of its operations for a substantial loss. This loss puts us in doubt of any financial recovery of our investment in affiliate. Although the full capital loss of the affiliate has not yet been triggered under the Code, we have concluded that it would be more likely than not a capital loss if the affiliate goes out of business or we abandon the partnership. A tax court case solidified capital loss treatment versus ordinary gain treatment in abandonments. The Tax Court's decision in Pilgrim's Pride Corporation v. Commissioner and Code Sections 165 and 1234A state that loss deductions related to worthless security abandonments would be treated as a capital loss versus an ordinary loss. In fiscal 2015, the Tax Court's decision in Pilgrim's Pride Corporation v. Commissioner was overturned by the federal Fifth Circuit Court of Appeals. Hence, we abandoned our partnership interest and recorded an ordinary loss on our 2015 federal tax return, thereby moving the asset and valuation allowance into our current tax provision and recording a current deduction. Because our position has a chance of being disallowed, we believe we cannot reach the more-likely-than not conclusion that this ordinary loss will be realized. Therefore, we have maintained an uncertain tax accrual. We will continue to evaluate the facts and circumstances of this case and adjust our accrual accordingly. As of April 30, 2016, we have foreign net operating loss (“NOL”) carryforwards of approximately $6,428 primarily related to our operations in Belgium and Ireland which have indefinite lives. A portion of the total NOL amounting to $219 is related to operations in Canada and expires in 2036. A deferred tax asset has been recorded for all NOL carryforwards totaling approximately $1,404. However, due to uncertainty in future taxable income in Ireland and Belgium, a full valuation allowance totaling approximately $1,337 has been recorded. If sufficient evidence of our ability to generate future taxable income in the jurisdictions in which we currently maintain a valuation allowance causes us to determine that our deferred tax assets are more likely than not realizable, we would release our valuation allowance, which would result in an income tax benefit being recorded in our consolidated statement of operations. Additional tax information: In the normal course of business, income tax authorities in various income tax jurisdictions both within the United States and internationally conduct routine audits of our income tax returns filed in prior years. Income tax years are open for the United States jurisdiction for fiscal years 2013 through 2015. International jurisdictions have open tax years varying by location beginning in fiscal 2006. We have no deferred tax liability recognized relating to our investment in foreign subsidiaries where the earnings have been indefinitely reinvested. If circumstances change and it becomes apparent that some or all of the undistributed untaxed earnings of a subsidiary will be remitted to the United States, we will accrue a tax expense at that time. We have approximately $9,067 of untaxed earnings which have indefinitely been reinvested. Determination of the amount of any unrecognized deferred income tax liability on these earnings is not practicable. We recognized an expense of $232, $14 and $20 in net interest and penalties during the years ended April 30, 2016, May 2, 2015 and April 26, 2014, respectively. Interest and penalties recognized are recorded in income taxes in our consolidated statements of operations. We had accrued $94 and $16 in net interest or penalties as of April 30, 2016 and May 2, 2015, respectively.
