Transactions include incurring liabilities, or issuing or offering to issue shares, options, and other equity instruments such as employee stock ownership plans and stock appreciation rights. Share-based payments to employees, including grants of employee stock options, are recognized as compensation expense in the consolidated financial statements based on their fair values. That expense is recognized over the period during which an employee is required to provide services in exchange for the award, known as the requisite service period (usually the vesting period). The Company adopted ASU 2019-07, <i>Improvements to Nonemployee Share-Based Payment Accounting</i>, effective January 1, 2019, which aligns the accounting treatment of nonemployee awards with employee awards.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"><span style="font: 10pt Times New Roman, Times, Serif"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><span style="font: 10pt Times New Roman, Times, Serif"> </span></p> <p id="xdx_844_eus-gaap--IncomeTaxPolicyTextBlock_zCG7SsRrAvyf" style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; background-color: white"><span style="font: 10pt Times New Roman, Times, Serif"><b><i>Income Taxes</i></b></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in; background-color: white"><span style="font: 10pt Times New Roman, Times, Serif"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in; background-color: white"><span style="font: 10pt Times New Roman, Times, Serif">Income taxes are provided for the tax effects of transactions reported in the consolidated financial statements and consist of taxes currently due and deferred taxes resulting from timing differences in recording of transactions for tax purposes and financial reporting purposes.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in; background-color: white"><span style="font: 10pt Times New Roman, Times, Serif"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in; background-color: white"><span style="font: 10pt Times New Roman, Times, Serif">The deferred tax assets and liabilities represent the future tax return consequences of those differences, which will either be taxable or deductible when the assets and liabilities are received or settled.

ASU 2020-06 simplifies the accounting for convertible debt by eliminating the beneficial conversion and cash conversion accounting models. Upon adoption of ASU 2020-06, convertible debt proceeds, unless issued with a substantial premium or an embedded conversion feature that is not clearly and closely related to the host contract, will no longer be allocated between debt and equity components. This modification will reduce the issue discount and result in less non-cash interest expense in financial statements. ASU 2020-06 also updates the earnings per share calculation and requires entities to assume share settlement when the convertible debt can be settled in cash or shares. ASU 2020-06 will be effective January 1, 2024, and a cumulative-effect adjustment to the opening balance of retained earnings is required upon adoption. Early adoption is permitted, but no earlier than January 1, 2021, including interim periods within that year. The adoption of ASU 2020-06 is not expected to have any impact on the Company’s consolidated financial statement presentation or disclosures subsequent to its adoption, with any effect being largely dependent on the composition and terms of outstanding financial instruments at the time of adoption.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in; background-color: white"><span style="font: 10pt Times New Roman, Times, Serif"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in; background-color: white"><span style="font: 10pt Times New Roman, Times, Serif">Recent accounting pronouncements issued by the FASB, including its Emerging Issues Task Force, the American Institute of Certified Public Accountants, and the Securities and Exchange Commission did not or are not believed by management to have a material impact o</span><span style="font-family: Times New Roman, Times, Serif">n the Company’s present or future consolidated financial statements.</span></p> <p id="xdx_85E_z7TKuueo83l6" style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; background-color: white"><span style="font: 10pt Times New Roman, Times, Serif"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><span style="font: 10pt Times New Roman, Times, Serif"> </span></p>

ASU 2020-06 simplifies the accounting for convertible debt by eliminating the beneficial conversion and cash conversion accounting models. Upon adoption of ASU 2020-06, convertible debt proceeds, unless issued with a substantial premium or an embedded conversion feature that is not clearly and closely related to the host contract, will no longer be allocated between debt and equity components. This modification will reduce the issue discount and result in less non-cash interest expense in financial statements. ASU 2020-06 also updates the earnings per share calculation and requires entities to assume share settlement when the convertible debt can be settled in cash or shares. ASU 2020-06 will be effective January 1, 2024, and a cumulative-effect adjustment to the opening balance of retained earnings is required upon adoption. Early adoption is permitted, but no earlier than January 1, 2021, including interim periods within that year. The adoption of ASU 2020-06 is not expected to have any impact on the Company’s consolidated financial statement presentation or disclosures subsequent to its adoption, with any effect being largely dependent on the composition and terms of outstanding financial instruments at the time of adoption.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in; background-color: white"><span style="font: 10pt Times New Roman, Times, Serif"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in; background-color: white"><span style="font: 10pt Times New Roman, Times, Serif">Recent accounting pronouncements issued by the FASB, including its Emerging Issues Task Force, the American Institute of Certified Public Accountants, and the Securities and Exchange Commission did not or are not believed by management to have a material impact o</span><span style="font-family: Times New Roman, Times, Serif">n the Company’s present or future consolidated financial statements.</span></p>

Vesting of options differs based on the terms of each option. The Company has valued the options at their date of grant utilizing the Black-Scholes option pricing model. As of the issuance of these consolidated financial statements, there was no active public market for the Company’s shares. Accordingly, the fair value of the options was determined based on the historical volatility data of similar companies, considering the industry, products and market capitalization of such other entities. The risk-free interest rate used in the calculations is based on the implied yield available on U.S. Treasury issues with an equivalent term approximating the expected life of the options as calculated using the simplified method. The expected life of the options used was based on the contractual life of the option granted. Stock-based compensation is a non-cash expense because we settle these obligations by issuing shares of our common stock from our authorized shares instead of settling such obligations with cash payments.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; background-color: white"><span style="font: 10pt Times New Roman, Times, Serif"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in; background-color: white"><span style="font: 10pt Times New Roman, Times, Serif">During the years ended December 31, 2020 and 2019, the Company had stock-based compensation expense of $-<span id="xdx_900_eus-gaap--ShareBasedCompensation_c20200101__20201231_pp0p0" title="Stock-based compensation expense">0</span>- and $<span id="xdx_901_eus-gaap--ShareBasedCompensation_c20190101__20191231_pp0p0" title="Stock-based compensation expense">49,692</span>, respectively, related to the vesting of stock options granted to the Company’s employees, directors, and consultants included in our reported net loss.

The Complaint alleges claims for breach of contract against the Company and tortious interference with contract against the Individual Defendants and MTF arising from the termination of the Professional Service Agreements, dated as of January 8, 2016, between the Company and each of the Plaintiffs. The Individual Defendants have been sued for actions taken by them in connection with their service to the Company as directors and/or officers of the Company. As such, the Company has certain indemnification obligations to the Individual Defendants. The Company and the Individual Defendants intend to vigorously defend against the allegations in the Complaint. Based on the very early stage of the litigation, it is not possible to estimate the amount or range of any possible loss arising from the expenditure of defense fees, a judgment or settlement of the matter.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"><span style="font: 10pt Times New Roman, Times, Serif"> </span></p>

Share-based payments to employees, including grants of employee stock options, are recognized as compensation expense in the consolidated financial statements based on their fair values.

ASU 2020-06 simplifies the accounting for convertible debt by eliminating the beneficial conversion and cash conversion accounting models. Upon adoption of ASU 2020-06, convertible debt proceeds, unless issued with a substantial premium or an embedded conversion feature that is not clearly and closely related to the host contract, will no longer be allocated between debt and equity components. This modification will reduce the issue discount and result in less non-cash interest expense in financial statements. ASU 2020-06 also updates the earnings per share calculation and requires entities to assume share settlement when the convertible debt can be settled in cash or shares. ASU 2020-06 will be effective January 1, 2024, and a cumulative-effect adjustment to the opening balance of retained earnings is required upon adoption. Early adoption is permitted, but no earlier than January 1, 2021, including interim periods within that year. The Company adopted ASU 2020-06 effective January 1, 2021.

ASU 2020-06 simplifies the accounting for convertible debt by eliminating the beneficial conversion and cash conversion accounting models. Upon adoption of ASU 2020-06, convertible debt proceeds, unless issued with a substantial premium or an embedded conversion feature that is not clearly and closely related to the host contract, will no longer be allocated between debt and equity components. This modification will reduce the issue discount and result in less non-cash interest expense in financial statements. ASU 2020-06 also updates the earnings per share calculation and requires entities to assume share settlement when the convertible debt can be settled in cash or shares. ASU 2020-06 will be effective January 1, 2024, and a cumulative-effect adjustment to the opening balance of retained earnings is required upon adoption. Early adoption is permitted, but no earlier than January 1, 2021, including interim periods within that year. The Company adopted ASU 2020-06 effective January 1, 2021. The adoption of ASU 2020-06 did not have any impact on the Company’s consolidated financial statement presentation or disclosures.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in; background-color: white"><span style="font: 10pt Times New Roman, Times, Serif"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in; background-color: white"><span style="font: 10pt Times New Roman, Times, Serif">Other recent accounting pronouncements issued by the FASB, including its Emerging Issues Task Force, the American Institute of Certified Public Accountants, and the Securities and Exchange Commission did not or are not believed by management to have a material impact on the Company’s present or future consolidated financial statements.</span></p>
