Concentrations of Credit and Operation Risk Concentrations of Credit Risk
Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of investments in time deposits, available-for-sale debt securities and trade receivables.
The Company places its investments with high credit quality financial institutions. At the time an investment is made, investments in commercial paper of industrial firms and financial institutions are rated A1, P1 or better. The Company invests in tax-exempt securities including municipal notes and bonds and bonds that are rated A, A2 or better and repurchase agreements, each of which have securities of the type and quality listed above as collateral.
The Company believes that concentrations of credit risk with respect to trade receivables are limited because a large number of geographically diverse customers make up the Company’s customer base, thus diluting the trade credit risk. The Company’s top three customers with the highest accounts receivable balances each accounted for approximately 18%, 17% and 6%, respectively, of the total consolidated accounts receivable balance as of December 26, 2020 and 15%, 9% and 8%, respectively, of the total consolidated accounts receivable balance as of December 28, 2019. However, the Company does not believe the receivable balance from these customers represents a significant credit risk based on past collection experience and review of their current credit quality.
