Such potential decreases in value, if deemed other&#13;than temporary, will cause the Company to record an impairment charge, which may have an impact on the trading values of USPB&amp;#8217;s&#13;Class A and Class B units. However, NBP&amp;#8217;s plants are all operational at the present time; it has been designated as an essential&#13;business during the COVID-19 pandemic; and its results of operations are highly profitable, as reflected in Note 6. As a result, we believe&#13;the fair value of our investment in NBP exceeds the carrying value.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&lt;i&gt;Cash and Cash&#13;Equivalents. &lt;/i&gt;The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents.&#13;As of March 27, 2021, the Company&amp;#8217;s balance sheet reflected Cash and cash equivalents of $51.2 million.

The Antitrust&#13;Cases are entitled &lt;i&gt;In re Cattle Antitrust Litigation&lt;/i&gt;, which was filed originally on April 23, 2019; &lt;i&gt;Peterson et al. v. JBS USA&#13;Food Company Holdings, et al&lt;/i&gt;., which was filed originally on April 26, 2019; &lt;i&gt;In re DPP Beef Litigation, &lt;/i&gt;which was filed originally&#13;on April 26, 2019; and &lt;i&gt;Erbert &amp;#38; Gerbert&amp;#8217;s, Inc. v. JBS USA Food Company Holdings, et al.&lt;/i&gt;, which was filed originally&#13;on June 18, 2020. The plaintiffs in the Antitrust Cases seek treble damages and other relief under the Sherman Antitrust Act, the Packers&#13;&amp;#38; Stockyards Act, the Commodities Exchange Act and attorneys&amp;#8217; fees. NBP is also a defendant in two class action lawsuits filed&#13;on January 7, 2020, alleging that it misrepresented the origin of its products in violation of the New Mexico Unfair Practices Act (the&#13;&amp;#8220;Labelling Cases&amp;#8221;). The Labelling Cases are entitled &lt;i&gt;Thornton v. Tyson Foods, Inc., et al.&lt;/i&gt;, filed in the New Mexico&#13;Second Judicial District Court, Bernalillo County, and &lt;i&gt;Lucero v. Tyson Foods, et al&lt;/i&gt;., filed in the New Mexico Thirteenth Judicial&#13;District Court, Sandoval County. The Labelling Cases were subsequently removed to the United States District Court, New Mexico District.&#13;The plaintiffs in the Labelling Cases seek treble damages and other relief and attorneys&amp;#8217; fees. NBP believes it has meritorious&#13;defenses to the claims in the Antitrust Cases and the Labelling Cases and intends to defend these cases vigorously, although there can&#13;be no assurance as to the outcome of these cases or the impact on NBP&amp;#8217;s consolidated financial position, results of operations and&#13;cash flows.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In addition to the&#13;antitrust litigation, NBP is subject to investigations by the United States Department of Justice and approximately 30 state attorneys&#13;general regarding industry cattle procurement practices. NBP is cooperating with these investigations and is working with the Department&#13;of Justice and the relevant states to provide information requested in connection with the investigations. NBP believes it has meritorious&#13;defenses to any potential claims that might arise out of these government investigations, although there can be no assurance as to the&#13;outcome of these investigations or the impact on NBP&amp;#8217;s consolidated financial position, results of operations and cash flows.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;NBP is a party&#13;to various other lawsuits and claims arising out of the operation of its business.

Such potential decreases in value, if deemed other&#13;than temporary, will cause the Company to record an impairment charge, which may have an impact on the trading values of USPB&amp;#8217;s&#13;Class A and Class B units. However, NBP&amp;#8217;s plants are all operational at the present time; it has been designated as an essential&#13;business during the COVID-19 pandemic; and its results of operations are highly profitable, as reflected in Note 6.

For the thirteen-week periods ended March 27, 2021 and March 28, 2020, 10% of USPB&amp;#8217;s net income was allocated&#13;to the Class A&amp;#8217;s and 90% to the Class B&amp;#8217;s. The net income allocated to the Class A and Class B units were then divided by&#13;the weighted-average number of Class A and Class B units outstanding for the period to determine the basic EPU for each respective class&#13;of unit.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Diluted EPU reflects&#13;the potential dilution that could occur to the extent that any outstanding dilutive Class A or Class B units were exercised.
