Similarly, we do not time the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation. Although we have not recently granted stock options to our named executive officers, the Compensation Committee generally approves the grant of annual equity awards for the Company&#x2019;s executive officers, including each of the named executive officers, in December of each year. In special circumstances, including the hiring or promotion of an individual or where the Compensation Committee determines it is in the best interest of the Company, the Compensation Committee may approve grants of equity awards at other times. During the year ended December&#160;31, 2025, we did not grant stock options or stock appreciation rights to any named executive officer during any period beginning four&#160;business days before and ending one business&#160;day after the filing of any Quarterly Report on Form&#160;10&lt;span class="nobreak"&gt;-Q&lt;/span&gt;, Annual Report on Form&#160;10&lt;span class="nobreak"&gt;-K&lt;/span&gt;, or Current Report on Form&#160;8&lt;span class="nobreak"&gt;-K&lt;/span&gt;, in each case that disclosed any material non&lt;span class="nobreak"&gt;-public&lt;/span&gt; information.&lt;/p&gt;</ecd:AwardTmgMnpiDiscTextBlock>

The Clawback Policy applies in the case of an accounting restatement due to the material noncompliance of the Company with any financial reporting requirement under the securities laws. The Clawback Policy applies to all incentive&lt;span class="nobreak"&gt;-based&lt;/span&gt; compensation, which is any compensation that is granted, earned, or vested based wholly or in part upon the attainment of a financial reporting measure, received by our executive officers.&lt;/p&gt;</ecd:ErrCompAnalysisTextBlock>
