As of December 31, 2019, the Company had a net deferred tax asset of approximately $5,143 offset by deferred tax liabilities of $770 derived from accelerated tax depreciation. This asset is primarily composed of net operating loss carryforwards (“NOLs”), research and development tax credits and costs, and deferred revenue. The NOLs total approximately $4,857 for federal and $7,526 for state purposes, with expirations starting in 2020 for state purposes. State NOLs of $1,209 expired in 2019.

 

During 2018, the Company generated no additional NOLs and during 2019, the Company generated $4,857 of additional federal NOLs. The deferred tax asset amounts are based upon management’s conclusions regarding, among other considerations, the Company’s current and anticipated customer base, contracts, and product introductions, certain tax planning strategies, and management’s estimates of future earnings based on information currently available, as well as recent operating results during 2019, 2018, and 2017. GAAP requires that all positive and negative evidence be analyzed to determine if, based on the weight of available evidence, the Company is more likely than not to realize the benefit of the deferred tax asset.

 

Management’s analysis of all available evidence, both positive and negative, provides support that the Company has the ability to generate sufficient taxable income in the necessary period to utilize the entire benefit for the deferred tax asset.

 

Should the factors underlying management’s analysis change, future valuation adjustments to the Company’s net deferred tax asset may be necessary. If future losses are incurred, it may be necessary to record a valuation allowance related to the Company’s net deferred tax asset recorded as of December 31, 2019. It cannot presently be estimated what, if any, changes to the valuation of the Company’s deferred tax asset may be deemed appropriate in the future. The 2019 federal and state NOLs and tax credit carryforwards could be subject to limitation if, within any three-year period prior to the expiration of the applicable carryforward period, there is a greater than 50% change in ownership of the Company.

 

For the year ended December 31, 2019, the Company is expecting a refund of a portion of the alternative minimum tax credits of approximately $72 (net). The alternative minimum tax legislation was repealed by the 2017 Tax Act.

 

The Company performed a comprehensive review of its portfolio of uncertain tax positions in accordance with recognition standards established by GAAP. In this regard, an uncertain tax position represents the Company’s expected treatment of a tax position taken in a filed tax return or planned to be taken in a future tax return that has not been reflected in measuring income tax expense for financial reporting purposes. As a result of this review, on January 1, 2020, the Company is not aware of any uncertain tax positions that would require additional liabilities or which such classification would be required. The amount of unrecognized tax positions did not change as of December 31, 2019, and the Company does not believe there will be any material changes in its unrecognized tax positions over the next twelve months.

 

Penalties and tax-related interest expense, of which there were no material amounts for the years ended December 31, 2019 and 2018, are reported as a component of income tax expense (benefit).

 

The Company files federal income tax returns, as well as multiple state and local jurisdiction tax returns. A number of years may elapse before an uncertain tax position is audited and finally resolved. While it is often difficult to predict the final outcome or the timing of resolution on any particular uncertain tax position, the Company believes that its allowances for income taxes reflect the most probable outcome. The Company adjusts these allowances, as well as the related interest, in light of changing facts and circumstances. The resolution of a matter would be recognized as an adjustment to the provision for income taxes and the effective tax rate in the period of resolution. The calendar years 2016, 2017, and 2018 are still open to IRS examination under the statute of limitations. The last IRS examination on the Company’s 2007 calendar year was closed with no change.
