Operating Loss Carryforwards, Expiration Dates The Company has federal net operating loss (NOL) carryforwards of $2.1 billion and $69 million of federal tax credit carryforwards as of February 2, 2019 that expire in 2032 through 2034. These NOL carryforwards arose prior to December 31, 2017 and are available to offset future taxable income. The Company may recognize additional NOLs in the future which, under the Tax Act, would not expire but would only be available to offset up to 80% of the Company’s future taxable income.    
Interest Limitation Interest Limitation: The Tax Act limits the Company’s interest deduction to 30% of tax earnings before interest, tax, depreciation and amortization beginning in 2018 through 2021. Thereafter, the interest deduction is limited to 30% of tax earnings before interest and taxes. Any disallowed interest in a year becomes a separate deferred tax asset with an indefinite carryforward period that can be utilized by the Company in a future tax year by an amount equal to its interest limitation in excess of its interest expense for that year. In 2018, the Company had net interest expense of $200 million disallowed which became a $48 million deferred tax asset on which a full valuation allowance was recorded.
