Its mission is to increase the quality&#13;of beef and long-term profitability of cattle producers by creating a fully integrated producer-owned beef processing system that&#13;is a global supplier of high quality, value-added beef products responsive to consumer desires. USPB operates an integrated cattle&#13;processing and beef marketing enterprise where consumer and processor demands and requirements are implemented through changes&#13;in genetics, feeding, and management. USPB&amp;#8217;s unitholders benefit from its supplier alliance with National Beef Packing Company,&#13;LLC (NBP) through (i) premiums received in excess of cash market prices for higher quality cattle, (ii) allocations of profits&#13;and potential distributions, (iii) potential unit price appreciation, and (iv) information that permits unitholders to make informed&#13;production decisions.&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;On August&#13;18, 2004, the shareholders of U.S. Premium Beef, Ltd. approved the conversion of the cooperative into a Delaware LLC.&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;On December&#13;5, 2011, USPB sold the majority of its membership interests in NBP to Leucadia National Corporation. Following the sale, USPB owned&#13;15.0729% of NBP&amp;#8217;s membership interests.&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;On November&#13;29, 2019, Jefferies Financial Group, Inc.

The evaluation&#13;included both quantitative and qualitative factors. The quantitative approach computed the fair value of the investment using a&#13;market based approach and resulted in a fair value that exceeded the carrying value. As a result of the analysis, USPB concluded&#13;that the carrying value of its investment in NBP was not impaired as of December 26, 2020 and December 28, 2019.&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;On June 10,&#13;2019, the members of NBP acquired 100% of the ownership interests in Iowa Premium, LLC (Iowa Premium) from Sysco Holdings, LLC&#13;for $153.2 million in cash after customary working capital adjustments. The cash utilized by NBP&amp;#8217;s members for the acquisition&#13;was distributed from NBP and immediately upon closing of the acquisition, each of the members of NBP contributed all its Iowa Premium&#13;ownership interests to NBP. The distribution, acquisition and contribution transactions were governed by several related agreements&#13;that resulted in NBP, in substance, acquiring 100% of the Iowa Premium ownership interests.&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;On November&#13;29, 2019, Jefferies Financial Group, Inc. sold its remaining ownership interest in NBP to a combination of NBM US Holdings, Inc.,&#13;a Delaware corporation owned by Marfrig Global Foods S.A.; NBPCo Holdings, LLC; and TMK Holdings, LLC. USPB elected to not participate&#13;in the acquisition and, as a result, USPB&amp;#8217;s ownership interest in National Beef remained at 15.0729%. In conjunction with&#13;the sale, NBP&amp;#8217;s members, including USPB, received proportionate special distributions and tax distributions from NBP.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;b&gt;&lt;i&gt;Property, Plant, and Equipment &lt;/i&gt;&lt;/b&gt;&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;Property,&#13;plant, and equipment are recorded at cost.

On June 24, 2020, CoBank unilaterally extended&#13;the Term Expiration Date under USPB&amp;#8217;s Amended and Restated Revolving Term Supplement from June 30, 2020 up to and including&#13;August 31, 2020. On July 13, 2020, USPB, and CoBank, ACB (&amp;#8220;CoBank&amp;#8221;), entered into a Credit Agreement, Amended and Restated&#13;Revolving Term Promissory Note (&amp;#8220;Promissory Note&amp;#8221;), and an Affirmation of Pledge Agreement (&amp;#8220;New Loan Agreements&amp;#8221;).&#13;The New Loan Agreements replace, amend and restate the arrangements between CoBank and USPB contained in that certain Master Loan&#13;Agreement, Revolving Term Loan Supplement to the Master Loan Agreement, Pledge Agreement, and Security Agreement dated July 26,&#13;2011, as amended.&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;The New Loan&#13;Agreements provide for a $1 million Revolving Term Commitment, carries a term of five years and matures on June 30, 2025. The Promissory&#13;Note defines Interest as equal to the One-Month LIBOR Index Rate or if LIBOR quotes are no longer available, CoBank will replace&#13;the LIBOR Index Rate with a replacement benchmark rate. The other terms and conditions of the Credit Agreement and the Revolving&#13;Term Loan Supplement continue the terms and conditions of the Prior Agreements without material modifications. The Affirmation&#13;of Pledge Agreement provides CoBank with a first-priority security interest in USPB&amp;#8217;s Membership Interests in, and Distributions&#13;from, National Beef Packing Company, LLC.&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;As of December&#13;26, 2020, USPB had no long-term debt outstanding. We had a $1.0 million Revolving Term Commitment with CoBank all of which was&#13;available. USPB was in compliance with the financial covenant under its Credit Agreement as of December 26, 2020 and Master Loan&#13;Agreement as of December 28, 2019.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;b&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160; (b)&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&#13;&lt;i&gt;Operating Leases&lt;/i&gt;&lt;/b&gt;&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 February&#13;2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2016-02, &lt;i&gt;Leases&lt;/i&gt;. The new standard&#13;requires the recognition of all leases that are longer than one year on the balance sheet, which will result in the recognition&#13;of a right of use asset and a corresponding lease liability. The new standard was effective for annual and interim periods beginning&#13;after December 15, 2018; USPB implemented the new standard effective December 30, 2018.&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;Upon review&#13;of its lease arrangements, USPB determined that its two office leases were subject to the new leasing standard. The Kansas City,&#13;MO office lease has a remaining term of approximately 4.2 years (assuming the final 3-year renewal is exercised). The Dodge City,&#13;KS office renewed its office lease in 2020 and has a remaining term of approximately 3.0 years. Neither lease agreement provides&#13;for renewals beyond the remaining terms. The monthly lease payment for the Kansas City office is $3,884, subject to annual Consumer&#13;Price Index adjustments, which are capped at 3% per year. The monthly lease payment for the Dodge City office is $1,025, which&#13;is not subject to adjustment. Both offices are used for general office use only. As of December 26, 2020, the present value of&#13;the remaining operating lease payments for the offices equaled $0.2 million and USPB&amp;#8217;s balance sheet reflected Right of Use&#13;Assets and Lease Obligations equal to that amount.

The phantom unit plan provides for the award of&#13;unit appreciation rights to management employees of USPB. USPB&amp;#8217;s CEO administers the phantom unit plan and awards &amp;#8220;Phantom&#13;Units&amp;#8221; (Class A and Class B Units) to employees in amounts determined by the CEO, subject to the total Phantom Unit amount&#13;approved by the Board of Directors of USPB. A total of 5,000 Class A phantom units and 5,000 Class B phantom units were awarded&#13;to management employees, with a strike price of $118 and $157, respectively. The closing of the Leucadia Transaction resulted in&#13;management employees receiving a payment under the management phantom unit plan. As a result of that payment, the strike price&#13;for both the Class A phantom units and Class B phantom units was satisfied and was reduced to $0. As a result of the retirement&#13;of one of USPB&amp;#8217;s employees on December 31, 2014, 50 Class A phantom units and 50 Class B phantom units were forfeited as&#13;they were not vested. One third of the retiring employee&amp;#8217;s vested phantom units were exercised and the appreciation rights&#13;paid in three tranches (retirement, and first and second anniversary of retirement). At the end of fiscal year 2020, 4,750 Class&#13;A phantom units and 4,750 Class B phantom units remain outstanding. The phantom units became fully vested in August 2015. For the&#13;management phantom unit plan, compensation expense of $3.2 million, $1.0 million, and $0.6 million was recognized in fiscal years&#13;2020, 2019, and 2018, respectively.&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;On November&#13;16, 2012, USPB&amp;#8217;s Board of Directors approved the issuance of an additional 1,500 Class A phantom units, with a strike price&#13;of $66.04 and 1,500 Class B phantom units, with a strike price of $73.70, to certain members of management, to be effective on&#13;January 28, 2013. The phantom units became fully vested in January 2018.

The cash incentive and bonus plans were designed to provide&#13;the financial incentive to the employees to influence USPB unitholder benefits and are only paid after certain levels of benefits&#13;have been achieved. As of December 26, 2020 and December 28, 2019, the Company had accrued $1.4 million and $1.4 million, respectively,&#13;for the cash incentive and bonus plans.

The 401(k) Plan provides for additional matching contributions by the Company, based on specific terms contained in the 401(k)&#13;Plan. The trustee of the 401(k) Plan, at the direction of each participant, invests the assets of the 401(k) Plan in designated&#13;investment options. The 401(k) Plan is intended to qualify under Section 401 of the Internal Revenue Code. Expenses related to&#13;the 401(k) Plan totaled approximately $0.1 million, $0.1 million, and $0.1 million for fiscal years 2020, 2019, and 2018, respectively.&lt;/p&gt;</us-gaap:CompensationAndEmployeeBenefitPlansTextBlock>

Per the terms and conditions of the Amended Agreement, NBP is required&#13;to purchase from USPB Class A unitholders, and USPB is required to cause to be sold and delivered from its Class A unitholders&#13;to NBP, a base amount of 735,385 (subject to adjustment) head of cattle per year. In fiscal years 2020, 2019, and 2018, USPB elected&#13;to increase the number of cattle that its Class A unitholders could deliver during USPB&amp;#8217;s delivery year by up to 10%. During&#13;fiscal years 2020, 2019, and 2018, USPB&amp;#8217;s Class A unitholders and associates provided approximately 23%, 23%, and 25%, respectively,&#13;of NBP&amp;#8217;s total cattle requirements. The purchase price for the cattle is determined by pricing grids, which, at all times,&#13;are required to be no less favorable than any other pricing grid being utilized by NBP and the pricing grid shall be competitive&#13;with NBP&amp;#8217;s major competitors for the purchase of cattle.

The cash utilized by NBP&amp;#8217;s members for the acquisition&#13;was distributed from NBP and immediately upon closing of the acquisition, each of the members of NBP contributed all its Iowa Premium&#13;ownership interests to NBP.

The plaintiffs in the Antitrust Cases seek treble damages and other relief&#13;under the Sherman Antitrust Act, the Packers &amp;#38; Stockyards Act, the Commodities Exchange Act and attorneys&amp;#8217; fees. NBP&#13;is also a defendant in two class action lawsuits filed on January 7, 2020, alleging that it misrepresented the origin of its products&#13;in violation of the New Mexico Unfair Practices Act (the &amp;#8220;Labelling Cases&amp;#8221;). The Labelling Cases are entitled &lt;i&gt;Thornton&#13;v. Tyson Foods, Inc., et al.&lt;/i&gt;, filed in the New Mexico Second Judicial District Court, Bernalillo County, and &lt;i&gt;Lucero v.

The evaluation&#13;included both quantitative and qualitative factors. The quantitative approach computed the fair value of the investment using a&#13;market based approach and resulted in a fair value that exceeded the carrying value. As a result of the analysis, USPB concluded&#13;that the carrying value of its investment in NBP was not impaired as of December 26, 2020 and December 28, 2019.&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;On June 10,&#13;2019, the members of NBP acquired 100% of the ownership interests in Iowa Premium, LLC (Iowa Premium) from Sysco Holdings, LLC&#13;for $153.2 million in cash after customary working capital adjustments. The cash utilized by NBP&amp;#8217;s members for the acquisition&#13;was distributed from NBP and immediately upon closing of the acquisition, each of the members of NBP contributed all its Iowa Premium&#13;ownership interests to NBP. The distribution, acquisition and contribution transactions were governed by several related agreements&#13;that resulted in NBP, in substance, acquiring 100% of the Iowa Premium ownership interests.&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;On November&#13;29, 2019, Jefferies Financial Group, Inc. sold its remaining ownership interest in NBP to a combination of NBM US Holdings, Inc.,&#13;a Delaware corporation owned by Marfrig Global Foods S.A.; NBPCo Holdings, LLC; and TMK Holdings, LLC.
