For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value and is then re-valued at each reporting date, with changes in the fair value reported in the statements of operations. For share-based derivative financial instruments, the Company used the Monte Carlo simulation model, the Black Scholes model and a binomial model to value the derivative instruments at inception and on subsequent valuation dates. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative liabilities are classified in the consolidated balance sheet as current or non-current based on whether or not net-cash settlement of the instrument could be required within 12 months after the balance sheet date.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0; text-align: justify; text-indent: 0.5in"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0"/> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0; text-align: justify; text-indent: 0.5in"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p id="xdx_84A_eus-gaap--EarningsPerSharePolicyTextBlock_zinffIuuGnil" style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"><i><span id="xdx_862_zVuXG88FiBzj">Net Income (Loss) per Share</span></i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0; text-align: justify; text-indent: 0.5in"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">Basic net income or loss per common share is computed by dividing net income or loss available to common stockholders by the weighted average number of common shares outstanding during the period.

For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value and is then re-valued at each reporting date, with changes in the fair value reported in the statements of operations. For share-based derivative financial instruments, the Company used the Monte Carlo simulation model, the Black Scholes model and a binomial model to value the derivative instruments at inception and on subsequent valuation dates. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative liabilities are classified in the consolidated balance sheet as current or non-current based on whether or not net-cash settlement of the instrument could be required within 12 months after the balance sheet date.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0; text-align: justify; text-indent: 0.5in"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0"/> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0; text-align: justify; text-indent: 0.5in"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p>

Net assets are recorded on the balance sheet for patents related to ADXS-HPV (AXAL), ADXS-HOT, ADXS-PSA, ADXS-HER2 and other products that are in development, and the <i>Lm </i>technology licensed from the University of Pennsylvania. There are various scenarios under which an impairment charge may be recorded, which include if a competitor were to gain FDA approval for a similar treatment before the Company, if future clinical trials fail to meet the targeted endpoints, or if a drug application is rejected or fails to be issued. Lastly, if the Company is unable to raise enough capital to continue funding its studies and developing its intellectual property, the Company would likely record an impairment to these assets.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify; text-indent: 0.5in"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">During the three months ended July 31, 2022, the Company identified the following indicators of impairment under ASC 360 indicating that the patents and license carrying amounts might not be recoverable:</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="font: 10pt Times New Roman, Times, Serif; vertical-align: top"> <td style="font: 10pt Times New Roman, Times, Serif; width: 0.25in"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></td> <td style="font: 10pt Times New Roman, Times, Serif; width: 0.25in"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">●</span></td> <td style="font: 10pt Times New Roman, Times, Serif; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">Adverse changes in the business climate for biotechnology companies, particularly raising capital; and</span></td></tr> <tr style="font: 10pt Times New Roman, Times, Serif; vertical-align: top"> <td style="font: 10pt Times New Roman, Times, Serif"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></td> <td style="font: 10pt Times New Roman, Times, Serif"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">●</span></td> <td style="font: 10pt Times New Roman, Times, Serif; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">A significant reduction in the Company’s market capitalization during the nine months ended July 31, 2022.</span></td></tr> </table> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; text-indent: 0.5in; margin: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">The Company performed an impairment test under ASC 350 on its patents owned and in-licensed intellectual property.
