On December 22, 2017, H.R.1, commonly known as the Tax Cuts and Jobs Act (the “Act”), was signed into law. Among other things, the Act reduces the corporate federal tax rate from 35% to 21% effective January 1, 2018. As a result the Company is required to remeasure, through income tax expense, deferred tax assets and liabilities using the enacted rate at which these items are expected to recover or settle. The re-measurement of the Company’s net deferred tax asset resulted in additional income tax expense of approximately $9.5 million. The Company also re-measured the net deferred tax asset as a result of the Illinois income tax increase effective as of July 1, 2017, resulting in a benefit of approximately $1.6 million.

At December 31, 2017, the Company had a $34.5 million federal net operating loss carryforward of which, $10.6 million expires in 2031, $8.6 million expires in 2032, and $15.3 million expires in 2033. The Company had a $74.1 million state net operating loss carryforward of which $73.6 million expires in 2025, and the rest expires starting in 2026. In addition, the Company had a $2.6 million alternative minimum tax credit carryforwards which do not expire and are now carried as tax receivables since, under the new federal law, the Company expects to recover the entire amount by 2022 via refund.
