The Tax Cuts and Jobs Act (the “Tax Act”) was enacted in December 2017. Among other provisions, the Tax Act reduced the U.S. federal corporate tax rate from 35% to 21% in 2018, required companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred and created new taxes on certain foreign-source earnings. As of December 31, 2019, the Company completed its accounting for the tax effects of enactment of the Tax Act without any material adjustments to its previous estimates.

As of December 31, 2020, the Company did not have a deferred tax liability related to its foreign earnings because it did not have any specific plans to repatriate funds from its international subsidiaries. The Company may do so in the future if a dividend can be remitted with no material tax impact.

In December 2016, the Company decided to exit the Bangalore, India branch operations of its TRS-RenTelco electronics division. The wind down of operations in India began in 2017. As a result, a valuation allowance was recorded against the deferred tax assets that resulted primarily from accumulated net operating loss carry forwards in India that management estimated the benefit of which will not be realized. As of December 31, 2020, the Company’s foreign net operating losses for tax purposes were $0.6 million. If not realized, these carry forwards will begin to expire in 2023.

For income tax purposes, deductible compensation related to share-based awards is based on the value of the award when realized, which may be different than the compensation expense recognized by the company for financial statement purposes which is based on the award value on the date of grant. The difference between the value of the award upon grant, and the value of the award when ultimately realized, creates either additional tax expense or benefit. In 2020, 2019 and 2018 exercise of share-based awards by employees resulted in an excess tax benefit of $1.9 million, $2.1 million and $2.0 million, respectively.

The Company recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. The Company evaluated all of its tax positions for which the statute of limitations remained open and determined there were no material unrecognized tax benefits as of December 31, 2020 and 2019. In addition, there have been no material changes in unrecognized benefits during 2020, 2019 and 2018.

The Company is subject to income taxes in the U.S. federal jurisdiction, and various states and foreign jurisdictions. Tax regulations within each jurisdiction are subject to interpretation of the related tax laws and regulations and require the application of significant judgment. With few exceptions, the Company is no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for the years before 2016.

Our income tax returns are subject to examination by federal, state and foreign tax authorities. There may be differing interpretations of tax laws and regulations, and as a result, disputes may arise with these tax authorities involving the timing and amount of deductions and allocation of income.

The Company recognizes interest and penalties related to unrecognized tax benefits in the provision (benefit) for income taxes in the accompanying Consolidated Statements of Income for all periods presented. Such interest and penalties were not significant for the years ended December 31, 2020, 2019 and 2018.
