As of December 31, 2024, we had $2.6 billion of total unpaid principal balance related to asset-backed financing agreements with mark-to-market collateral provisions and $6.5 billion of total unpaid principal balance related to asset-backed financing agreements that do not include mark-to-market collateral provisions.  Repurchase agreements and other forms of collateralized financing are uncommitted and renewable at the discretion of our lenders and, as such, our lenders could determine to reduce or terminate our access to future borrowings at virtually any time.

We review margin calls made by counterparties and assess them for reasonableness by comparing the counterparty valuation against our valuation determination.  When we believe that a margin call is unnecessary because our assessment of collateral value differs from the counterparty valuation, we typically hold discussions with the counterparty and attempt to resolve the
