The Company's standard credit terms vary from 30 to 120 days, depending on the class of trade and customary terms within a territory, so accounts receivable are affected by the mix of purchasers within the period. As is typical in the Company's business, extended credit terms may occasionally be offered as a sales promotion or for certain sales. For sales to the Company’s distributor in Brazil, the Company has agreed to credit terms of up to 90 days subsequent to clearance of the product by the Ministry of Health in Brazil. The Company has $1.4 million of trade receivables as of December 31, 2023 due from its distributor in Brazil for sales recognized in fiscal 2021, which the Company expects to be paid within one year.

The components of accounts receivable consisted of the following at December 31, 2023 and September 30, 2023:

At December 31, 2023 and at September 30, 2023, no customers had a current accounts receivable balance that represented greater than 10% of current assets.

At December 31, 2023, two customers had an accounts receivable balance greater than 10% of net accounts receivable, representing 67% of net accounts receivable in the aggregate. At September 30, 2023, three customers had an accounts receivable balance greater than 10% of net accounts receivable, representing 71% of net accounts receivable in the aggregate. 

For the three months ended December 31, 2023, there were three customers whose individual net revenue to the Company exceeded 10% of the Company’s net revenues, representing 66% of the Company’s net revenues in the aggregate. For the three months ended December 31, 2022, there were three customers whose individual net revenue to the Company exceeded 10% of the Company’s net revenues, representing 64% of the Company’s net revenues in the aggregate.

The Company maintains an allowance for credit losses for estimated losses resulting from the inability of its customers to make required payments on accounts receivable. Management determines the allowance for credit losses by identifying troubled accounts and by using historical experience applied to an aging of accounts. Management also periodically evaluates individual customer receivables and considers a customer’s financial condition, credit history, and the current economic conditions. In the case of a bankruptcy filing or other similar event indicating the collectability of specific customer accounts is no longer probable, a specific allowance for credit losses may be recorded to reduce the related receivable to the amount expected to be recovered. Accounts receivable are charged-off when deemed uncollectible. The Company has an allowance for credit losses of $3.9 million related to the total amount of receivables due from The Pill Club due to The Pill Club’s Chapter 11 bankruptcy, filed on April 18, 2023. The Company has an open claim with The Pill Club bankruptcy estate for these receivables but it is unlikely that any amounts will be recovered.

There were no material changes in the allowance for credit losses for the three months ended December 31, 2023 and 2022. Recoveries of accounts receivable previously charged off are recorded when received. In the global public health sector, the Company’s customers are primarily large global agencies, non-government organizations, ministries of health and other governmental agencies, which purchase and distribute FC2 for use in HIV/AIDS prevention and family planning programs. In the U.S. prescription channel, the Company’s customers include primarily telehealth providers.
