While the CARES Act provides sweeping tax changes in response to the COVID-19 pandemic, some of the more significant provisions which are expected to impact the Company's financial statements include removal of certain limitations on utilization of net operating losses, increasing the loss carryback period for certain losses to five years, and increasing the ability to deduct interest expense, as well as amending certain provisions of the previously enacted Tax Cuts and Jobs Act. Consistent with prior years, the Company expects to continue to generate net losses for the foreseeable future. The Company currently has significant federal and state deferred tax assets attributed to prior net operating losses and research and experimentation tax credits. These deferred tax assets are fully reserved.
