The value of our assets may be affected by prepayment speeds on mortgage loans. Prepayment speed is the measurement of how quickly borrowers pay down the UPB of their loans or how quickly loans are otherwise liquidated or charged off. Generally, in a declining interest rate environment, prepayment speeds tend to increase. Conversely, in an increasing interest rate environment, prepayment speeds tend to decrease. When we acquire Servicing Related Assets or RMBS, we anticipate that the underlying mortgage loans will prepay at a projected rate generating an expected cash flow (in the case of Servicing Related Assets) and yield. If we purchase assets at a premium to par value and borrowers prepay their mortgage loans faster than expected, the corresponding prepayments on our assets may reduce the expected yield on such assets because we will have to amortize the related premium on an accelerated basis. In addition, we will have to reinvest the greater amounts of prepayments in that lower rate environment, thereby affecting future yields on our assets. If we purchase assets at a discount to par value, and borrowers prepay their mortgage loans slower than expected, the decrease in corresponding prepayments may reduce the expected yield on assets because we will not be able to accrete the related discount as quickly as originally anticipated.
If prepayment speeds are significantly greater than expected, the fair value of the Servicing Related Assets could be less than their fair value as previously reported on our consolidated balance sheets. Such a reduction in the fair value of the Servicing Related Assets would have a negative impact on our book value. Furthermore, a significant increase in prepayment speeds could materially reduce the ultimate cash flows we receive from the Servicing Related Assets, and we could receive substantially less than what we paid for such assets. Our balance sheet, results of operations and cash flows are susceptible to significant volatility due to changes in the fair value of, or cash flows from, the Servicing Related Assets as interest rates change.
A slower than anticipated rate of prepayment due to an increase in market interest rates also will cause the life of the related RMBS to extend beyond that which was projected. As a result, we would have an asset with a lower yield than current investments for a longer period of time. In addition, if we have hedged our interest rate risk, extension may cause the security to be outstanding longer than the related hedge, thereby reducing the protection intended to be provided by the hedge.
Voluntary and involuntary prepayment rates may be affected by a number of factors including, but not limited to, the availability of mortgage credit, the relative economic vitality of, or natural disasters affecting, the area in which the related properties are located, the servicing of the mortgage loans, possible changes in tax laws, other opportunities for investment, homeowner mobility and other economic, social, geographic, demographic and legal factors, none of which can be predicted with any certainty.
We attempt to reduce the exposure of our MSRs to voluntary prepayments through the structuring of recapture agreements with Aurora’s subservicers. Under these agreements, the subservicer attempts to refinance specified mortgage loans. The subservicer sells the new mortgage loan to the applicable Agency, transfers the related MSR to Aurora and then subservices the new mortgage loan on behalf of Aurora. See “Item 8. Consolidated Financial Statements and Supplementary Data—Note 7. Transactions with Related Parties” for information regarding Aurora’s recapture agreements.
With respect to our business operations, increases in interest rates, in general, may over time cause:
• the interest expense associated with our borrowings to increase;
• the value of our assets to fluctuate;
• the coupons on any adjustable-rate and hybrid RMBS we may own to reset, although on a delayed basis, to higher interest rates;
• prepayments on our RMBS to slow, thereby slowing the amortization of our purchase premiums and the accretion of our purchase discounts; and
• an increase in the value of any interest rate swap agreements we may enter into as part of our hedging strategy.
Conversely, decreases in interest rates, in general, may over time cause:
• prepayments on our RMBS to increase, thereby accelerating the amortization of our purchase premiums and the accretion of our purchase discounts;
• the interest expense associated with our borrowings to decrease;
• the value of our assets to fluctuate;
• a decrease in the value of any interest rate swap agreements we may enter into as part of our hedging strategy; and
• coupons on any adjustable-rate and hybrid RMBS assets we may own to reset, although on a delayed basis, to lower interest rates.
Regardless, we cannot predict the impact future actions by the Federal Reserve will have on our business, and any such actions may negatively impact us.
