Interest rate sensitivity is derived from models that are dependent on inputs and assumptions provided by third parties, assumes there are no changes in mortgage spreads and assumes a static portfolio. Actual results could differ materially from these estimates.
Represents the estimated dollar change in net interest income expressed as a percent of net interest income based on asset yields and cost of funds as of such date. It includes the effect of periodic interest costs on our interest rate swaps, but excludes costs associated with our forward starting swaps and other supplemental hedges, such as swaptions and U.S. Treasury securities. Amounts also exclude costs associated with our TBA position and TBA dollar roll income/loss, which are accounted for as derivative instruments in accordance with GAAP. Base case scenario assumes interest rates and forecasted CPR of 8.4% and 8.0% as of December 31, 2017 and 2016, respectively. As of December 31, 2017, rate shock scenarios assume a forecasted CPR of 13%, 10%, 7% and 7% for the -100, -50, +50 and +100 basis points scenarios, respectively. As of December 31, 2016, rate shock scenarios assume a forecasted CPR of 10%, 9%, 7% and 7% for such scenarios, respectively. Estimated dollar change in net interest income does not include the impact of retroactive "catch-up" premium amortization adjustments due to changes in our forecasted CPR. Down rate scenarios assume a floor of 0% for anticipated interest rates.
Includes the effect of derivatives and other securities used for hedging purposes.
Estimated dollar change in investment portfolio value expressed as a percent of the total fair value of our investment portfolio as of such date.
Estimated dollar change in portfolio value expressed as a percent of tangible stockholders' equity, net of the aggregate preferred stock liquidation preference, as of such date.
Prepayment Risk
Prepayment risk is the risk that our assets will be repaid at a faster rate than anticipated. Interest rates and numerous other factors affect the rate of prepayments, including housing prices, general economic conditions, loan age, size and loan-to-value ratios, and the pace of GSE buyouts of delinquent loans underlying our securities among other factors. Generally, prepayments increase during periods of falling mortgage interest rates and decrease during periods of rising mortgage interest rates. However, this may not always be the case.
If our assets prepay at a faster rate than anticipated, we may be unable to reinvest the repayments at acceptable yields. If the proceeds are reinvested at lower yields than our existing assets, our net interest income would be negatively impacted. We also amortize or accrete premiums and discounts we pay or receive at purchase relative to the stated principal of our assets into interest income over their projected lives using the effective interest method. If the actual and estimated future prepayment experience differs from our prior estimates, we are required to record an adjustment to interest income for the impact of the cumulative difference in the effective yield.
Extension Risk
Similar to prepayment risk, extension risk is the risk that our assets will be repaid at a slower rate than anticipated. Extension risk generally increases when interest rates rise. In this scenario, we may have to finance our investments at potentially higher costs without the ability to reinvest principal into higher yielding securities because borrowers prepay their mortgages at a slower pace than originally expected, adversely impacting our net interest margin, and thus our net interest income.
Spread Risk
Spread risk is the risk that the market spread between the yield on our assets and the yield on benchmark interest rates, such as U.S. Treasury rates and interest rate swap rates, may vary. The inherent spread risk associated with our investment securities and the resulting fluctuations in fair value of these securities can occur independent of interest rates and may relate to other factors impacting the mortgage and fixed income markets, such as actual or anticipated monetary policy actions by the Fed, liquidity, or
