Net operating loss carryforwards |  |  | $ 43,800,000
Net operating loss carryforwards description |  | Some of the key changes include eliminating the 80% of taxable income limitation by allowing corporate entities to fully utilize NOLs to offset taxable income in 2018, 2019 and 2020, allowing NOLs originating in 2018, 2019 and 2020 to be carried back five years, enhanced interest deductibility, and retroactively clarifying the immediate recovery of qualified improvement property costs rather than over a 39-year recovery period. |
Net operating loss carryforward available for use |  | Approximately $43.8 million of net operating losses incurred prior to 2020 will be unable to offset future taxable income and have been reserved via a valuation allowance to reduce the deferred tax asset to the expected realizable amount, leaving $2.9M available for use which expire at various dates through 2038 and the residual which never expire. |
