The Company has determined that it is more likely than not that it will not realize its deferred tax asset. As such, a valuation allowance totaling $1,222 is recorded at May 31, 2017 and is included in deferred income taxes liability in the accompanying consolidated balance sheet. A primary factor in the assessment of this non-cash charge is that the Company is in a cumulative loss position over the three-year period ended May 31, 2017.
The Company follows the guidance of ASC Topic 740, Income Taxes, Accounting for Uncertainty in Income Taxes – an interpretation of FASB Statement No. 109, which requires that income tax positions must be more likely than not to be sustained based solely on their technical merits in order to be recognized. The Company has recorded no liability for uncertain tax positions. In the event the Company had uncertain tax positions, the Company would elect to record interest and penalties from unrecognized tax benefits in the tax provision.
The Company files income tax returns in the U.S. federal jurisdiction and various states. Because of closure of an Internal Revenue Service examination, the Company is generally no longer subject to U.S. federal income tax or state and local tax examinations for years before 2012.
