Income Taxes

We file a consolidated federal income tax return, consolidated unitary tax returns in certain states and other separate state income tax returns for our subsidiary companies.

The income tax provision for interim periods is generally determined based upon the expected effective income tax rate for the full year and the tax rate applicable to certain discrete transactions in the interim period. To determine the annual effective income tax rate, we must estimate both the total income (loss) before income tax for the full year and the jurisdictions in which that income (loss) is subject to tax. The actual effective income tax rate for the full year may differ from these estimates if income (loss) before income tax is greater than or less than what was estimated or if the allocation of income (loss) to jurisdictions in which it is taxed is different from the estimated allocations. We review and adjust our estimated effective income tax rate for the full year each quarter based upon our most recent estimates of income (loss) before income tax for the full year and the jurisdictions in which we expect that income will be taxed.

On March 27, 2020, the Coronavirus Aid, Relief and Economic Security Act (the "CARES Act") was enacted and signed into law. The CARES Act includes several provisions for corporations including increasing the amount of deductible interest, allowing companies to carryback certain net operating losses (“NOLs”) and increasing the amount of NOLs that corporations can use to offset income. The CARES Act did not materially affect our second quarter or year-to-date income tax provision. We do expect to receive an additional tax refund of $14.0 million from the carryback of NOLs to prior periods. We are currently

assessing the future implications of these provisions within the CARES Act on our condensed consolidated financial statements, but do not expect the impact to be material.

The effective income tax rate for the six months ended June 30, 2020 and 2019 was 14% and 29%, respectively. Differences between our effective income tax rate and the U.S. federal statutory rate are the impact of state taxes, foreign taxes, non-deductible expenses, changes in reserves for uncertain tax positions and excess tax benefits or expense from the exercise and vesting of share-based compensation awards ($1.1 million expense in 2020 and $0.8 million benefit in 2019). Additionally, in 2020, we had a net discrete tax provision charge of $3.5 million related to state deferred rate changes and state NOL valuation allowance reductions.

Deferred tax assets totaled $13.3 million at June 30, 2020, which includes the tax effect of state NOL carryforwards. We recognize state NOL carryforwards as deferred tax assets, subject to valuation allowances. At each balance sheet date, we estimate the amount of carryforwards that are not expected to be used prior to expiration of the carryforward period. The tax effect of the carryforwards that are not expected to be used prior to their expiration is included in the valuation allowance.
