We use a third-party model to calculate the weighted average lives of our investments in securities. Weighted average life is calculated based on expectations for estimated prepayments for the underlying mortgage loans of our investments in securities. These estimated prepayments are based on assumptions such as interest rates, current and future home prices, housing policy and borrower incentives. The weighted average lives of our investments in securities at March 31, 2025 and December 31, 2024 in the table above are based upon market factors, assumptions, models and estimates from the third-party model and also incorporate management’s judgment and experience. The actual weighted average lives of these securities could be longer or shorter than estimated.
