Certain of the Company’s wholly-owned subsidiaries have entered into accounts receivable factoring arrangements with a financial institution (the “Factor”) with termination dates that started in September 2021 but automatically renew for successive one-year periods (absent either party's written election to terminate, which has not occurred). Pursuant to the terms of the agreements, the Company, from time to time, sells to the Factor certain of its accounts receivable balances on a recourse basis for credit-approved accounts. The Factor remits 95% of the contracted accounts receivable balance for a given month to the Company (the “Advance Amount”) with the remaining balance, less fees, to be forwarded once the Factor collects the full accounts receivable balance from the customer.

For long-term contracts with credit worthy customers, the Factor may advance, at their discretion, unearned future contract amounts. Unearned advances are secured by all factored and non-factored long-term contract cash receipts, which are remitted directly to the Factor by the customer. Earned and unearned components included in Advances from factoring arrangement are as follows:


	December 31,
($ in thousands)	2021		2020
Purchased accounts receivable	$	7,390	$	7,924
Unearned future contract advances		6,885		16,473
Total	$	14,275	$	24,397

On March 9, 2021, the Company and the Factor entered into a Letter-of-Intent and Memo of Understanding related to the application of proceeds received from the USPS in the first quarter of 2021, arising out of the settlement agreements described in Note 1, Description of Business and Significant Accounting Policies. Pursuant to the agreement, the parties agreed that the Factor would remit $11.0 million of net proceeds to the Company and that the Factor would retain approximately $6.9 million of net proceeds and apply that amount to reduce the outstanding principal amount of the Company’s factoring advances. The parties further agreed that the Company will repay the remaining balance of approximately $6.9 million due under the factoring arrangement in 48 equal monthly installments beginning January 1, 2022 and that the Factor would apply funds held in reserve against the approximately $0.8 million remaining balance of advances made to the Company during September 2020. The parties also agreed to work together to wind down their factoring relationship, including waiver of any applicable termination fees.

The Factor may require, at their discretion at any time, the Company to repay unearned future contract advances or purchased accounts receivable that have not been paid by the customer. Financing costs are primarily comprised of an interest rate of Prime (subject to a 4% floor) plus 2.0% (resulting in a rate of 6% as of December 31, 2021 and 2020). There is also a factor fee of 0.25% of the face amount of the invoice factored and an associated penalty increase for purchased accounts that remain unpaid for 31 days. Total interest and financing fees for factored receivables for the years ended December 31, 2021 and 2020 were $1.3 million and $1.7 million, respectively. The fees are included in interest expense in the consolidated statements of operations.
