In addition, we have entered into a reverse factoring arrangement with Banco Santander Mexico, S.A. (“Santander”) pursuant to which a participating supplier receives the original invoice amount discounted at an agreed rate, and we pay Santander the original amount of the invoice within 60 days after the supplier collects the invoice from Santander. The aggregate limit of amounts invoiced under this arrangement is Ps.350,000 thousand. Pursuant to the terms of this arrangement, we have created a trust, which is meant to be a source of payment in the case of a payment default, into which cash flows coming from 419 stores in a minimum aggregate amount of Ps.300,000 thousand are deposited and released so long as no payment default occurs. See Note 3.12 to our audited consolidated financial statements as of December 31, 2022 and 2021 and for the years ended December 31, 2022, 2021 and 2020 for more information about this arrangement.
On June 2, 2023, we and HSBC Mexico, S.A. (“HSBC”) entered into a reverse factoring transaction (the “HSBC Supplier Finance Agreement”) and a credit facility (the “HSBC Credit Line,” and together with the HSBC Supplier Finance Agreement, the “HSBC Agreement”). The aggregate principal amount financeable under the HSBC Agreement is Ps.450,000 thousand. Pursuant to the terms of the HSBC Supplier Finance Agreement, participating suppliers may discount their invoices with HSBC, and they will receive the original invoice amount discounted at an agreed rate and we will then pay HSBC the original amount by the earlier of: (x) the date HSBC pays the supplier plus the number of credit days originally agreed to with the supplier, and (y) 90 days after the supplier collects the invoice from HSBC. The supplier elects which invoices are entered into the factoring transaction. Once entered, such invoices are novated and the liability of the Company to cover such invoice is extinguished. Invoices that are not discounted with HSBC are payable to the supplier at the original maturity date. There are no commissions or interests payable to HSBC when invoices are discounted, and only an opening commission of Ps.2,250 thousand was paid for entering into the agreement, however, we receive a commission from HSBC for each factoring transaction and we must pay penalties in case of late payment. In addition, under the terms of the HSBC Agreement, the Company must comply with certain covenants, including restrictions on dividends. Additionally, pursuant to the terms of the HSBC Agreement, we have created a trust, which is meant to be a source of payment in the case of a payment default, into which Ps.540,000 thousand of cash flows have to be deposited each month and are released so long as no payment default occurs. Drawdowns on the HSBC Credit Facility are payable within 90 days and accrue interest at a rate of TIIE+3.25% and matures within 36 months.
