Product candidates currently under development will require significant additional research and development efforts, including extensive preclinical and clinical testing and regulatory approvals, prior to commercialization.

National, state and local governments in affected regions have implemented and may continue to implement varying safety precautions, including quarantines, border closures, increased border controls, travel restrictions, shelter-in-place orders and shutdowns, business closures, cancellations of public gatherings and other measures. The extent and severity of the impact on the Company’s business and clinical trials will be determined largely by the extent to which there are disruptions in the supply chains for its research and product candidates, delays in the conduct of ongoing and future clinical trials, or reductions in the number of patients accessing AbbVie’s HCV regimens, or any combination of those events. In addition, AbbVie experienced a decline in HCV sales compared to periods prior to March 2020 as a result of a reduction in patients accessing AbbVie’s HCV regimens due to the COVID-19 pandemic.</span><span style="color:rgba(0,0,0,1);white-space:pre-wrap;font-weight:normal;font-size:10.0pt;font-family:"Times New Roman", serif;min-width:fit-content;"> </span></p><p style="text-indent:0.0%;font-size:10.0pt;margin-top:6.0pt;font-family:Times New Roman;margin-bottom:0.0pt;text-align:left;"><span style="background-color:rgba(0,0,0,0);color:rgba(0,0,0,1);white-space:pre-wrap;font-weight:normal;font-size:10.0pt;font-family:"Times New Roman", serif;min-width:fit-content;">The full extent to which the COVID-19 pandemic will directly or indirectly impact the Company’s business, results of operations and financial condition will depend on future developments that are highly uncertain and cannot be accurately predicted, including new information that may emerge concerning COVID-19 and its variants and public health actions taken to contain it, as well as the cumulative economic impact of both of those factors.</span></p>

Estimates are periodically reviewed in light of changes in circumstances, facts and experience.

CY2022	us-gaap	Risks And Uncertainties In Entitys Business RisksAndUncertaintiesInEntitysBusiness	In response to the COVID-19 pandemic, the CARES Act was signed into law in March 2020. The CARES Act lifted certain deduction limitations originally imposed by the Tax Cuts and Jobs Act of 2017 (the “Tax Act”). Under the CARES Act, the Company was permitted to carryback net operating losses for up to five years for losses generated in fiscal 2018 through fiscal 2021. Net operating loss carrybacks were previously prohibited under the Tax Act. The CARES Act also eliminated the 80% of taxable income limitations by allowing corporate entities to fully utilize net operating loss carryforwards to offset taxable income in fiscal years 2018, 2019 or 2020. In addition, the CARES Act made qualified improvement property eligible for 15-year cost-recovery and 100% bonus depreciation. The enactment of the CARES Act resulted in a $28,721 and $8,581 income tax benefit related to a federal net operating loss carryback at the previously enacted 35% rate in the Company’s consolidated financial statements during the years ended September 30, 2021 and 2020, respectively.
