We buy certain products, including beta-alanine, from a limited number of raw material suppliers who meet our quality standards.

Financial instruments that subject us to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. We place our cash and cash equivalents with highly rated financial institutions. Credit risk with respect to receivables is concentrated with two of our largest customers, whose receivable balances collectively represented 59.0% of gross accounts receivable at December 31, 2020 and 65.7% at June 30, 2020. As of December 31, 2020 and June 30, 2020, we had a receivable balance of $3.3 million from a former contract manufacturing customer that we have recorded a bad debt reserve equal to 100% of this outstanding balance and thus did not reflect it in the percentages listed above. Additionally, amounts due related to our beta-alanine raw material sales were 4.5% of gross accounts receivable at December 31, 2020, and 2.5% of gross accounts receivable at June 30, 2020. Concentrations of credit risk related to the remaining accounts receivable balances are limited due to the number of customers comprising our remaining customer base.
