The Company manages this risk by maintaining all deposits in high quality financial institutions and periodically performing evaluations of the relative credit standing of the financial institutions. When assessing credit risk the Company considers whether the credit risk exists at both the individual and group level. Consideration is given to the activity, region and economic characteristics when assessing if there exists a group concentration risk. At <em style="font: inherit;"> December 31, 2020</em>, the Company had <span style="-sec-ix-hidden:c69956486">two</span> customers with a combined accounts receivable balance of 23% of the total accounts receivable. At December <em style="font: inherit;">31,</em> <em style="font: inherit;">2019</em>, the Company had <em style="font: inherit;">no</em> customer with an accounts receivable balance greater than 10% of the total accounts receivable. At <em style="font: inherit;"> December 31, 2020</em><em style="font-weight: inherit; font-style: normal;"> </em>and <em style="font: inherit;">2019</em>, the <em style="font: inherit;">five</em> largest customer accounts receivables balances totaled $36.8 million and $18.6 million, respectively, or approximately 40% and 23% of the respective total accounts receivable balances. The Uniform and Related Products segment has a substantial number of customers, <em style="font: inherit;">none</em> of which accounted for more than <em style="font: inherit;">10%</em> of that segment’s <em style="font: inherit;">2020</em> net sales. The Remote Staffing Solutions segment’s largest customer represented 14% of that segment’s <em style="font: inherit;">2020</em> external revenues. <em style="font: inherit;">No</em> customer accounted for more than 10% of the Promotional Products segment’s <em style="font: inherit;">2020</em> net sales.</p> <p style="margin: 0pt; font-family: "Times New Roman",Times,serif; font-size: 10pt;"> </p> <p style="margin: 0pt; font-family: "Times New Roman",Times,serif; font-size: 10pt;">The Uniform and Related Products segment’s principal fabrics used in the manufacture of its finished goods are cotton, polyester and cotton-synthetic blends. The majority of such fabrics are sourced in China. The Promotional Products segment relies on the supply of different types of raw materials as well as textiles, including plastic, glass, fabric and metal. The vast majority of these raw materials are principally sourced from China, either directly by BAMKO or its suppliers. If we are unable to continue to obtain our raw materials and finished products from China or if our suppliers are unable to source raw materials from China, it could significantly disrupt our business. Further, the Company’s suppliers generally source or manufacture finished goods in parts of the world that <em style="font: inherit;"> may </em>be affected by economic uncertainty, political unrest, labor disputes, health emergencies, or the imposition of duties, tariffs or other import regulations by the United States.</p> <p style="margin: 0pt; font-family: "Times New Roman",Times,serif; font-size: 10pt;"> </p>
