We have cash balances at four domestic banks totaling approximately $25.3 million that is in excess of federally insured limits.<br/> <br/> Financial instruments that could potentially subject us to concentrations of credit risk are trade accounts receivable; however, such risks are limited due to the large number of customers comprising our customer base and their dispersion across geographic regions. We have approximately 24 customers with accounts receivable balances of between $1 million and $10 million and <span style="-sec-ix-hidden:c435">five</span> customers with a balance greater than $10 million, with the largest being approximately $22 million.<br/> <br/> We have several large customers that account for a significant portion of our sales.

Five of the ten customers are food distributors who sell our product to many end users.<br/> <br/> About 30% of our employees are covered by collective bargaining agreements.<br/> <br/> None of our vendors supplied more than 10% of our ingredients and packaging in 2024, 2023 or 2022.</p> <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"> </p> <p style="font-family: 'Times New Roman', Times, serif; font-size: 10pt; margin: 0pt; text-align: left"> </p> <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;">Virtually all of our accounts receivable are due from trade customers. Credit is extended based on evaluation of our customers’ financial condition and collateral is not required. Accounts receivable payment terms vary and are stated in the financial statements at amounts due from customers net of an allowance for estimated credit losses. At September 28, 2024 and September 30, 2023, our accounts receivables were $189.2 million and $198.1 million, net of an allowance for estimated credit losses of $3.2 million and $3.2 million. Accounts receivable outstanding longer than the payment terms are considered past due. We determine our allowance by considering a number of factors, including the length of time trade accounts receivable are past due, our previous loss history, customers’ current ability to pay their obligations to us, and the condition of the general economy and the industry as a whole. We write off accounts receivable when they become uncollectible, and payments subsequently received on such receivables are credited to the allowance for estimated credit losses.</p> <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"> </p>
