In September 2022, we entered into a Receivables Purchase Agreement with Wells Fargo Bank N.A., under which we may sell certain US-originated accounts receivable balances up to a maximum amount of $110.0 million at any given time. In return for these sales, we receive a cash payment equal to the face value of the receivables less a financing charge.
We account for these transfers as sales. We have no retained interest in the transferred receivables other than administrative responsibilities, and Wells Fargo has no recourse for any credit risk. We estimate that the implicit servicing fees for an arrangement of this size and type would be immaterial.
For the three months ended December 31, 2022, the gross fair value of accounts receivables transferred to Wells Fargo and derecognized from our balance sheet was $209.6 million. In exchange for these sales, we received $208.5 million of cash. The balance, representing a loss on sale from these transfers, is included within our selling, general and administrative expenses. We have recorded these transactions within our operating cash flows. The effective annual interest rate under this program was 4.8%.
